Description

Technical Field

[0001] This utility model relates to the technical field of foam plastic processing equipment, and more specifically, to a foam plastic compaction device. Background Technology

[0002] The production and recycling of polystyrene foam often generates a large amount of bulky, lightweight polystyrene foam waste or unprocessed products. Because these polystyrene foams contain a large amount of air, they occupy a significant amount of space, causing great inconvenience for storage and transportation, increasing warehousing costs and logistics expenses. Furthermore, in subsequent processing or reprocessing stages, they need to be compressed to reduce their volume in order to improve processing efficiency and resource utilization.

[0003] Based on the above, the inventors have discovered that traditional compaction devices often employ simple hydraulic or mechanical extrusion methods, resulting in low compaction efficiency, low automation, and uneven compaction effects. This is particularly problematic for loose, large-volume foam plastics, which often require manual assistance for feeding and unloading, increasing the workload of operators and hindering continuous production. Furthermore, some devices have inadequate structural designs, leading to blockages and accumulation of foam plastics during compaction, affecting overall processing efficiency and equipment stability. Therefore, in view of these issues, the inventors have researched and improved existing structures to provide a foam plastic compaction device with greater practical value. Utility Model Content

[0014] 3. Beneficial effects

[0015] Compared with existing technologies, the advantages of this utility model are:

[0016] (1) In this scheme, by setting up a spiral feeding structure, the drive motor drives the spiral rod to rotate in the sleeve, and continuously and evenly pushes the foam plastic entering from the feed hopper into the compression box, avoiding manual feeding and realizing automated feeding. This effectively solves the problem of high labor intensity caused by the need for manual feeding in traditional devices. At the same time, the spiral pushing method can perform preliminary compression of the foam plastic, reduce its bulkiness, lay the foundation for the subsequent compaction process, and improve the overall compaction efficiency.

[0017] (2) In this solution, by using the adjustment component, the stepper motor drives the lead screw to rotate, which drives the moving seat and the top base plate to move smoothly along the linear guide rail, so that the foam plastic can be automatically sent out from the compression box after being compressed, making unloading more convenient and faster, greatly improving its ease of use, realizing a continuous production process, further improving processing efficiency, and reducing the labor intensity of operators.

[0038] Example:

[0039] Please see Figures 1-4 A foam plastic compaction device includes a mounting frame 1, a compression chamber 2 fixedly connected to the inner wall of the mounting frame 1, a movable door 3 rotatably connected to the bottom of one side of the compression chamber 2 via a pin, a side plate 4 fixedly connected to the top of one side of the compression chamber 2, a sleeve 5 fixedly connected to one side of the side plate 4, a spiral rod 6 rotatably connected inside the sleeve 5, a drive motor 7 mounted at one end of the sleeve 5, one end of the spiral rod 6 extending to the outside of the sleeve 5 and being driven by the output shaft of the drive motor 7 via a coupling, and a feed hopper 8 provided at the top of the sleeve 5. Two linear guide rails 9 are installed on the bottom inner wall of the compression box 2. A slide block 10 is slidably connected to the top outer periphery of the linear guide rails 9. A base plate 11 is fixedly connected between the tops of the two slide blocks 10. An adjustment component 12 is provided between the bottom of the base plate 11 and the bottom inner wall of the compression box 2. A lower pressure plate 13 is provided inside the compression box 2. A hydraulic cylinder module 14 is rotatably connected between the top of the lower pressure plate 13 and the top inner wall of the mounting frame 1 through a pin. In use, the hydraulic cylinder module 14 includes a hydraulic cylinder, a hydraulic drive module and other structures. All structures work together to complete the compaction of the foam plastic.

[0040] See Figure 3 The side plate 4 has a feed inlet on one side, and the other end of the sleeve 5 is open. The inside of the sleeve 5 is connected to the inside of the compression box 2 through the feed inlet.

[0041] See Figure 3 A feeding port is provided at the top of one end of the sleeve 5, and the feeding hopper 8 is connected to the inside of the sleeve 5 through the feeding port.

[0042] See Figure 4 The adjustment assembly 12 includes two bearing seats 1201 fixed to the inner wall of the bottom of the compression box 2 and a stepper motor 1202 fixedly installed on the other side of the compression box 2. A lead screw 1203 is rotatably connected between the two bearing seats 1201 through the bearing. A movable seat 1204 is threaded on the outer circumference of the lead screw 1203. The top of the movable seat 1204 is fixedly connected to the bottom of the base plate 11.

[0043] See Figure 4 One end of the lead screw 1203 extends to the outside of the compression box 2 and is connected to the output shaft of the stepper motor 1202 via a coupling.

[0044] See Figure 4 The movable seat 1204 has a threaded hole, and the movable seat 1204 is connected to the outer circumferential thread of the lead screw 1203 through the threaded hole.

[0045] In use: First, the foam plastic to be compacted is fed into the sleeve 5 through the feed hopper 8. The drive motor 7 is started, and its output shaft drives the screw rod 6 to rotate inside the sleeve 5. The screw rod 6 uses its spiral blades to push the foam plastic forward. During the pushing process, the inner wall of the sleeve 5 compresses the foam plastic, achieving initial compression. Then, the initially compressed foam plastic enters the compression chamber 2 through the feed port on the side plate 4 and falls onto the bottom plate 11. When the foam plastic accumulates to a certain amount on the bottom plate 11, the hydraulic cylinder module 14 is activated, and its piston rod extends downward, pushing the lower pressure plate 13 towards the bottom plate 11 to perform secondary compaction of the foam plastic on the bottom plate 11. The pressure of the lower pressure plate 13 can be adjusted according to the type of foam plastic and the compaction requirements through the control system of the hydraulic cylinder module 14 to ensure uniform compaction. After compaction, the hydraulic cylinder module 14 drives the lower pressure plate 13 to reset. Then, the stepper motor 1202 starts, and its output shaft drives the lead screw 1203 to rotate. Since the moving seat 1204 is threadedly connected to the lead screw 1203, and the base plate 11 is slidably connected to the linear guide rail 9 through the slide seat 10, when the lead screw 1203 rotates, the moving seat 1204 drives the base plate 11 to move along the linear guide rail 9 towards the movable door 3. When the base plate 11 moves to the position of the movable door 3, the movable door 3 rotates around the pin under the push of the base plate 11 and opens. Then the base plate 11 continues to move, pushing the compacted foam plastic out of the compression box 2, completing the unloading. After unloading, the stepper motor 1202 reverses, drives the base plate 11 to reset, and the movable door 3 closes under its own gravity. The device can then enter the next round of compaction. The whole process realizes the automated continuous operation of feeding, compaction, and unloading.
