Description

Technical Field

[0001] This utility model relates to the technical field of food packaging production and processing equipment, and in particular to an adjustable screw extrusion device. Background Technology

[0002] Food packaging is an integral part of food products and one of the major processes in the food industry. It protects food from biological, chemical, and physical damage during its journey from the factory to the consumer. It also helps maintain the stable quality of the food itself. Furthermore, it facilitates consumption and is the primary element in representing the food's appearance, attracting consumers. Especially with the increasing use of lunch boxes and fast food containers, office workers and students are the main users of disposable lunch boxes. Moreover, with the improvement of living standards and the gradual formation of environmental awareness, lunch boxes have shifted from foam containers to environmentally friendly ones. Plastics used in these containers have characteristics such as low toxicity, high melting point, strong plasticity, simple production, and relatively low cost, thus becoming one of the mainstream materials for manufacturing lunch boxes.

[0003] Screw extruders are a common type of equipment for producing plastic lunch boxes. For example, a high-speed screw extrusion device for lunch boxes in the prior art consists of a mounting frame, an extrusion box mounted on the mounting frame, and a feed hopper located on the upper side of the extrusion box. One side of the extrusion box has a connected double-tube cavity, and one side of the double-tube cavity has a discharge port. Inside the double-tube cavity, there are two relatively inclined shafts. One end of each shaft is rotatably connected to the extrusion box, and both shafts are connected to helical blades. One side of the helical blades is located inside the extrusion box and below the feed hopper. A drive motor is mounted on the outside of the extrusion box, and a drive gear is sleeved on the shaft of the drive motor. Both shaft ends are connected to driven gears, and the drive gear and driven gear mesh for transmission.

[0004] To accommodate lunch boxes of different sizes and thicknesses, the extrusion head of the screw extruder needs to be adjusted during extrusion. However, adjusting the extrusion head requires the user to first disassemble the extrusion head with tools and then reassemble it with tools, which is cumbersome and reduces processing efficiency.

[0005] Therefore, it is necessary to provide an adjustable screw extrusion device to solve the above-mentioned technical problems. Utility Model Content

[0028] First Embodiment

[0029] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 ,in, Figure 1 A schematic diagram of the structure of a first embodiment of an adjustable screw extrusion device provided by this utility model; Figure 2 for Figure 1 The diagram shows another perspective of the structure; Figure 3 for Figure 1 The diagram shows a cross-sectional view of the extrusion assembly. Figure 4 for Figure 1 The enlarged schematic diagram of part A is shown. An adjustable screw extrusion device includes: a base plate 1, with support plates 11 fixedly installed at both ends of the top of the base plate 1, and a top plate 12 fixedly installed on the top of the support plates 11;

[0030] A twin-screw extrusion assembly 2 is disposed on the top of the top plate 12;

[0031] A fixed plate 3 is fixedly installed at the bottom of the top plate 12. A drive motor 31 is fixedly installed on one side of the fixed plate 3. A lead screw 32 is fixedly installed at the output end of the drive motor 31. A movable plate 33 is threadedly connected to the outer side of the lead screw 32.

[0032] A rotating shaft 4 is slidably connected to the inside of a support plate 11. A replacement plate 42 is fixedly installed at one end of the rotating shaft 4. The replacement plate 42 has multiple threaded holes 43 inside. Two baffles 41 are fixedly installed on the outer side of the other end of the rotating shaft 4.

[0033] Multiple extrusion components 5 are respectively disposed on the inner side of multiple threaded holes 43. Each of the multiple extrusion components 5 includes a mounting ring 51, a retaining ring 52 and an extrusion head 53. The mounting ring 51 is threaded to the inner side of the threaded hole 43. The extrusion head 53 is fixedly installed at one end of the mounting ring 51. The retaining ring 52 is fixedly installed on the outer side of the connection between the extrusion head 53 and the mounting ring 51.

[0034] The twin-screw extrusion assembly 2 is a twin-screw extruder in the prior art;

[0035] By installing the fixing plate 3, it can serve to install and support the drive motor 31 during use, and make the lead screw 32 threadedly connected inside the moving plate 33, thereby driving the moving plate 33 to move back and forth.

[0036] The input end of the twin-screw extrusion assembly 2 is fixedly equipped with a feed frame 22, and the output end of the twin-screw extrusion assembly 2 is fixedly equipped with an output head 21, the output end of which is located on the inner side of the mounting ring 51.

[0037] When in use, the feed box 22 is used to add raw materials, and the output head 21 is used to output the raw materials.

[0038] One end of the lead screw 32 is rotatably connected to the side of one of the support plates 11.

[0039] By rotatably connecting one end of the lead screw 32 to the side of the support plate 11, the stability of the lead screw 32 during rotation can be increased.

[0040] The two baffles 41 are respectively disposed on both sides of the movable plate 33, and the top of the movable plate 33 abuts against the bottom of the top plate 12.

[0041] By setting the two baffles 41, the movable plate 33 can be limited during use, so that when the movable plate 33 moves, it can drive the rotating shaft 4 to move.

[0042] The working principle of the adjustable screw extrusion device provided by this utility model is as follows:

[0043] When using the device, if the extrusion assembly 5 needs to be replaced, the user can start the drive motor 31, which will drive the lead screw 32 to make a threaded connection inside the moving plate 33, thereby moving the moving plate 33 to one side of the replacement plate 42. When the replacement plate 42 moves, it will move the extrusion assembly 5 away from the extrusion head 53. Then, the user can rotate the replacement plate 42, which will drive the extrusion assembly 5 and the rotating shaft 4 to rotate until the extrusion assembly 5 to be used is moved to one end of the output head 21. Then, the user can start the drive motor 31 again, which will make the lead screw 32 make a threaded connection inside the moving plate 33, thereby moving the moving plate 33 away from the replacement plate 42. Then, the mounting ring 51 will wrap around the outer side of the output head 21.

[0044] Compared with related technologies, the adjustable screw extrusion equipment provided by this utility model has the following beneficial effects:

[0045] The screw extrusion assembly 2, drive motor 31, lead screw 32, moving plate 33, rotating shaft 4, baffle 41, replacement plate 42, threaded hole 43, and extrusion assembly 5 work together to adjust the extruded size. When the extruded size needs to be adjusted, the user only needs to start the drive motor 31, move the replacement plate 42 away from the output head 21, and then rotate the replacement plate 42 until the extrusion assembly 5 of the appropriate size is on the side of the output head 21. Then, start the drive motor 31 again to fit the mounting ring 51 onto the outer side of the output head 21. The extruded size can then be adjusted. The operation is convenient and quick, increasing processing efficiency.

The sealing post 62 is fixedly installed on one side of the mounting plate 61, and the sealing ring 63 is sleeved on the outer side of the sealing post 62.

[0049] The outer side of the sealing ring 63 abuts against the inner side of the extruder head 53.

[0050] The pull ring 64 is fixedly installed on the other side of the mounting plate 61.

[0051] The working principle of the adjustable screw extrusion device provided by this utility model is as follows:

[0052] When in use, when the other replacement blocking components 6 are not in use, the user can insert the blocking component 6 into the inner side of the extruder head 53, so that the sealing post 62 and the sealing ring 63 are in the inner side of the extruder head 53, thereby playing a blocking role.

[0053] Compared with related technologies, the adjustable screw extrusion equipment provided by this utility model has the following beneficial effects:
