At present, the filling machinery technology is widely used in the development, design and manufacturing process of food and beverage packaging. The development trend is to continuously improve the automation degree of the single machine, improve the automation control level and production capacity of the whole packaging production line, and greatly improve the food. The quality of beverage packaging production equipment products enhances its domestic and international competitiveness. Strong supply capacity
Bone screws, also known as fracture fixation screws, are commonly used in clinical practice to fix orthopedic implants.
Bone screws are usually used to fix internal fractures or dislocations by directly screing into two different bone blocks or fixing an internal implant such as a bone plate to achieve fracture fixation, position the bone and promote its healing. Bone screws are used in a wide range of areas, including the shoulder, elbow, hip, knee, spine, etc. For example, pedicle screw systems are used for spinal fusion, and compression bone screws are commonly used for foot and ankle surgery or fixation of other fractures under pressure. Similar to traditional mechanical screws, the main structures of bone screws also include nail cap, nail body, and nail tip. Screws can be used to fix bone plates or bone fragments. When used for the former, they are called plate screws, and when used for the latter (to prevent the collapse of bone fragments), they are called positional screws. The latter can be inserted into the plate holes, and can be placed on the bone alone (also known as compression screws). Compression screws can be used to increase interfragment pressure.
(1) The screw cap
The screw cap has three main functions: the first is to optimize the force. The protruding cap makes the contact area between the screw and bone larger, increases the load area, optimizes the local force at the screw insertion site, and reduces the risk of bone rupture caused by excessive stress. The second is the positioning effect. The prominent cap makes the bone nail can only be screwed into a certain depth to prevent the whole bone nail from being screwed into the bone completely. The third function is to provide the position of force application by rotating the force groove at the cap to move the bone nail forward and drive it into the bone. Now, the force groove is mostly inner hexagonal, which does not require axial force to maintain the actuator in the center position and is suitable for a wider range of fractures.
(2) Screw the body
The size of the nail body determines the strength and fatigue resistance of the bone nail. The larger the diameter of the nail body, the stronger the strength will be, and the corresponding fatigue resistance will be better. In addition to the diameter of the nail body, the pitch and tooth depth of the screw body thread are also the key parameters of the nail body design. Different thread design has an important effect on the pressure and occlusal performance of the screw.
(3) Screw tip
Tapping is the process of phalangeal nail cutting thread in the bone. According to the shape of the nail tip, the bone nail can be divided into self-tapping nail and non-self-tapping nail. The nail tip of the self-tapping nail is sharper and can be directly screwed into the bone without pre-drilling. Usually, self-tapping screws are used for Cancellous bone, and the bone is compressed when the screw is inserted, so as to increase the bone density of the occlusal part locally and enhance the occlusal effect. However, when inserting screws in Cortical bone, the screw channel is generally pre-punched, and then the bone screw is screwed. Usually, the self-tapping screw is not directly used to prevent the bone screw from being stuck or damaged because the cortical bone is too hard.

Multifunction
The same equipment can be used for hot packaging of various beverages such as tea drinks, coffee drinks, soy milk drinks and juice drinks; both glass bottles and polyester bottles can be packaged. The packaging speed of the speed and high-yield carbonated beverage packaging machine is up to 2000 cans/min. The German KHS company, SEN company and KRONES company have packaging valves of 165, 144 and 178, respectively. The non-carbonated beverage packaging machine has 50-100 packaging valves and a packaging speed of up to 1500 cans/min. The packaging valves of Zhengzhou Xinghuo Packaging Machinery Co., Ltd., Jiangsu Qunjie Packaging Machine Co., Ltd. and Guangzhou Aote Filling Machine have 12 heads, 14 heads and 24 heads respectively, and the packaging speed is up to 1200 cans/min. The range is 5-60 ml, 10-125 ml, 25-250 ml, 50-500 ml, 100-1000 ml, 250-2500 ml, 500-5000 ml.
High technology, high performance
The level of self-control and the efficiency of the entire line are high. The on-line detection device and the metering device are fully equipped, and can automatically detect various parameters and measure accurately. High-tech packaging technology products integrating machine, electricity, gas, light and magnetism are constantly emerging.
Such as a beverage packaging line, the combination of micro-computer parts, control software, packaging and closure, the combination of real productivity and theoretical technology. The supplier can provide engineering design, installation and commissioning for the user, and finally accept the user acceptance. For example, the design of Spark packaging machinery is to use the simulation design technology to store various machine units in the form of database into the computer, digitize the drawings and input them into the computer, and then input the actual production indicators and data, possible failures, etc. into the computer. The engineer operates according to the actual working conditions, demonstrating the production capacity, the scrap rate, the production link matching, the bottleneck of the production line, etc., and the model can be modified according to the user's opinion until the user is satisfied.
Current trends in the development of filling machinery
Today's filling machinery, especially beverage, beer filling machinery and food packaging machinery, has the characteristics of high speed, complete set, high degree of automation and good reliability, and is also the trend of the development of the filling machinery industry.
