The utility model includes a placement box, with a fixed frame fixedly connected to the outer wall of the placement box. A rotating shaft is rotatably connected to the top outer wall of the fixed frame, and a second fixed frame is fixedly connected to the top outer wall of the rotating shaft. A hydraulic rod is fixedly connected to the bottom outer wall of the second fixed frame. This utility model incorporates a pressure plate.

Description

Technical Field

[0001] This utility model belongs to the technical field of plastic bottle processing equipment, and in particular relates to a compaction device for recycling waste plastic bottles. Background Technology

[0002] Plastic bottles are mainly made of materials such as polyethylene or polypropylene with the addition of various organic solvents. Plastic bottles widely use polyester (PET), polyethylene (PE), and polypropylene (PP) as raw materials, adding appropriate organic solvents, and then, after high-temperature heating, are formed into plastic containers through blow molding, extrusion blow molding, or injection molding using plastic molds.

[0003] When using existing equipment, users may have different needs for compacting plastic bottles, and it is difficult to disassemble and replace the pressure plate, which leads to reduced work efficiency. Therefore, we propose a compaction device for recycling waste plastic bottles. Utility Model Content

[0004] The purpose of this utility model is to provide a compaction device for recycling waste plastic bottles. By using a pressure plate, it solves the problem that existing equipment is difficult to disassemble and replace due to the different compaction requirements of users, which leads to reduced work efficiency.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a compaction device for recycling waste plastic bottles, including a placement box, a fixed frame fixedly connected to the outer wall of the placement box, a rotating shaft rotatably connected to the top outer wall of the fixed frame, a second fixed frame fixedly connected to the top outer wall of the rotating shaft, a hydraulic rod fixedly connected to the bottom outer wall of the second fixed frame, a collection box slidably connected to the inner wall of the placement box, and an adjustment mechanism provided on the outer wall of the placement box.

[0007] The adjusting mechanism includes a worm gear, the outer wall of which is rotatably connected to the outer wall of the fixed frame. A worm wheel is fixedly connected to the outer wall of the rotating shaft, and the outer wall of the worm wheel meshes with the outer wall of the worm gear. A pressure plate is slidably connected to the bottom outer wall of the hydraulic rod. Several limiting grooves are formed on the inner wall of the pressure plate. Insert rods are slidably connected to the inner walls of the limiting grooves. Several springs are sleeved on the outer walls of the insert rods. A fixing plate is fixedly connected to the outer walls of the springs. The inner wall of the fixing plate is fixedly connected to the outer wall of the insert rods. A fixing block is slidably connected to the outer wall of the insert rods. The inner wall of the fixing block is fixedly connected to the outer wall of the springs. The outer wall of the fixing block is fixedly connected to the outer wall of the pressure plate. A demolding mechanism is provided on the inner wall of the placement box.

[0008] Furthermore, the demolding mechanism includes a first motor, the outer wall of the first motor is fixedly connected to the outer wall of the placement box, the outer wall of the placement box is fixedly connected to a plurality of slide rails, and the inner wall of the slide rails is slidably connected to a rack.

[0009] Furthermore, the bottom output end of the first motor is fixedly connected to a transmission shaft via a coupling. A gear is fixedly connected to the outer wall of the transmission shaft. The outer wall of the gear meshes with the outer walls of several racks. A nail plate is fixedly connected to the outer wall of the racks. The outer wall of the nail plate is slidably connected to the inner wall of the slide rail.

[0010] Furthermore, a limiting plate is fixedly connected to the inner wall of the placement box near the nail plate, and the inner wall of the limiting plate is slidably connected to the outer wall of the nail plate. A second motor is fixedly connected to the outer wall of the placement box near the fixing frame.

[0011] Furthermore, the inner wall of the placement box is rotatably connected with several bidirectional threaded rods, and the outer wall of the bidirectional threaded rods on the left side is fixedly connected to the bottom output end of the second motor.

[0012] Furthermore, a pulley is fixedly connected to the outer wall of the bidirectional threaded rod, and a belt is drivenly connected to the outer wall of the pulley.

[0013] Furthermore, the outer wall of the bidirectional threaded rod is rotatably connected to several sliders, the outer wall of the sliders is slidably connected to the inner wall of the placement box, and the inner wall of the placement box is slidably connected to a filter plate.

[0014] Furthermore, a number of fixed seats are fixedly connected to the bottom outer wall of the filter plate, and the fixed seats and the outer wall of the slider are rotatably connected by connecting rods.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model incorporates a pressure plate. When the equipment is needed, the plastic bottle is placed in the placement box, and then the hydraulic rod is activated. The downward movement of the hydraulic rod causes the pressure plate to move downward, squeezing the plastic bottle and compacting it. When it is necessary to change to a pressure plate of a different size, multiple insert rods are pulled outward simultaneously. During the outward pulling process, the insert rods compress springs and retract. When the insert rods are completely disengaged from the limiting groove, the pressure plate can be removed normally. This allows users to freely disassemble and replace the pressure plate according to actual processing needs, making it more suitable for processing requirements. At the same time, the installation and disassembly of the device are simple and convenient, and the position of the pressure plate can be adjusted to assist in the subsequent demolding operation.

[0017] 2. This utility model incorporates a filter plate. When the equipment is in use, starting the second motor causes the left-side bidirectional threaded rod to rotate, which in turn rotates the pulley on the left-side bidirectional threaded rod. The rotation of the pulley in turn rotates the belt, causing the right-side bidirectional threaded rod to rotate. The simultaneous rotation of multiple bidirectional threaded rods causes multiple sliders to slide towards the center position, thereby moving the connecting rod. Because the fixed seat and the limiting shaft limit the movement trajectory of the connecting rod, the residual water in the plastic bottle can be discharged during the compaction process, and the residual water can be filtered. After the plastic bottle is compacted, it can be ejected, achieving demolding.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-6 As shown, this utility model is a compaction device for recycling waste plastic bottles, including a placement box 1. A fixing frame 101 is fixedly connected to the outer wall of the placement box 1. A rotating shaft 102 is rotatably connected to the top outer wall of the fixing frame 101. A fixing frame 2 103 is fixedly connected to the top outer wall of the rotating shaft 102. The rotating shaft 102 can support and limit the fixing frame 2 103 as a whole, so that the fixing frame 2 103 can only move in a circle around the rotating shaft 102. A hydraulic rod 104 is fixedly connected to the bottom outer wall of the fixing frame 2 103. A collection box 105 is slidably connected to the inner wall of the placement box 1. An adjustment mechanism 2 is provided on the outer wall of the placement box 1. The collection box 105 can collect the residual water overflowing from the plastic bottles, which is convenient for users to process in a centralized manner later.

[0030] The adjusting mechanism 2 includes a worm gear 201, the outer wall of which is rotatably connected to the outer wall of the fixed frame 101. A worm wheel 202 is fixedly connected to the outer wall of the rotating shaft 102, and the outer wall of the worm wheel 202 meshes with the outer wall of the worm gear 201. A pressure plate 203 is slidably connected to the bottom outer wall of the hydraulic rod 104. When the worm gear 201 is rotated, the rotation of the worm gear 201 can drive the worm wheel 202 to rotate, which in turn drives the rotating shaft 102 to rotate, thereby adjusting the position of the fixed frame 103 so that the pressure plate 203 is no longer aligned with the opening of the placement box 1. The inner wall of the pressure plate 203 has several limiting grooves 204, and the inner walls of the several limiting grooves 204 are slidably connected to insert rods 205. Several springs 206 are sleeved on the outer wall of the insert rods 205. A fixing plate 207 is fixedly connected to the outer wall of the container. When the insertion rod 205 is pulled outward, the fixing plate 207 will compress the spring 206 and cause it to retract. The fixing plate 207 can limit the position of the spring 206 and prevent the spring 206 from falling off. The inner wall of the fixing plate 207 is fixedly connected to the outer wall of the insertion rod 205. A fixing block 208 is slidably connected to the outer wall of the insertion rod 205. The fixing block 208 can limit the position of the insertion rod 205, so that the insertion rod 205 can only slide within the fixing block 208, and at the same time, it can prevent the insertion rod 205 from falling off. The inner wall of the fixing block 208 is fixedly connected to the outer wall of the spring 206. The outer wall of the fixing block 208 is fixedly connected to the outer wall of the pressure plate 203. A demolding mechanism 3 is provided on the inner wall of the container 1.

[0031] The demolding mechanism 3 includes a first motor 301. The outer wall of the first motor 301 is fixedly connected to the outer wall of the placement box 1. Several slide rails 302 are fixedly connected to the outer wall of the placement box 1. A rack 303 is slidably connected to the inner wall of the slide rails 302. The slide rails 302 can limit the movement trajectory of the rack 303 to prevent it from falling off, and can also limit the movement trajectory of the nail plate 304, so that it can only slide within the slide rails 302. The bottom output end of the first motor 301 is fixedly connected to a drive shaft 315 via a coupling. A gear 314 is fixedly connected to the outer wall of the drive shaft 315. The outer wall of the gear 314 meshes with the outer walls of several racks 303. The nail plate 304 is fixedly connected to the outer wall of the racks 303. The first motor 301 is activated. When the first motor 301 is activated, its rotation drives the transmission shaft 315 to rotate. The rotation of the transmission shaft 315 drives the gear 314 to rotate, causing the slide rail 302 to slide. The outer wall of the nail plate 304 is slidably connected to the inner wall of the slide rail 302. A limit plate 305 is fixedly connected to the inner wall of the placement box 1 near the nail plate 304. The inner wall of the limit plate 305 is slidably connected to the outer wall of the nail plate 304. A second motor 306 is fixedly connected to the outer wall of the placement box 1 near the fixing frame 101. When the second motor 306 is activated, its rotation drives the bidirectional threaded rod 307 to rotate, causing the pulley 308 to rotate. The rotation of the pulley 308 drives the belt 309 to rotate, thereby causing multiple bidirectional threaded rods 307 to rotate simultaneously.

[0032] The inner wall of the placement box 1 is rotatably connected to several bidirectional threaded rods 307. The outer wall of the bidirectional threaded rod 307 on the left side is fixedly connected to the bottom output end of the second motor 306. A pulley 308 is fixedly connected to the outer wall of the bidirectional threaded rod 307. The pulley 308 can limit the position of the belt 309 to prevent the belt 309 from being misaligned, and at the same time can drive the belt 309. The belt 309 is drivenly connected to the outer wall of the pulley 308. Several sliders 310 are rotatably connected to the outer wall of the bidirectional threaded rod 307. The outer wall of the sliders 310 is slidably connected to the inner wall of the placement box 1. A filter plate 311 is slidably connected to the inner wall of the 1. The filter plate 311 can filter the residual water flowing out of the plastic bottle. At the same time, the filter plate 311 can limit the plastic bottle. When used with the placement box 1 and the pressure plate 203, the plastic bottle can be compacted. Several fixed seats 313 are fixedly connected to the bottom outer wall of the filter plate 311. The fixed seats 313 and the outer wall of the slider 310 are rotatably connected to the connecting rods 312. By adjusting the position of the connecting rods 312, the position of the filter plate 311 can be adjusted, so that the filter plate 311 can be raised, and then the compacted plastic bottle can be demolded.

[0033] One specific application of this embodiment is:

[0034] When the equipment is needed, the plastic bottle is placed in the placement box 1, and then the hydraulic rod 104 is activated. The downward movement of the hydraulic rod 104 causes the pressure plate 203 to move downward, squeezing the plastic bottle and compacting it. When a different size pressure plate 203 needs to be replaced, multiple insert rods 205 are pulled outward simultaneously. During the outward pulling process, the insert rods 205 compress the spring 206, causing it to retract. When the insert rods 205 are completely disengaged from the limiting groove 204, the pressure plate 203 can be removed normally, and the spring 206 can... Through its own elasticity, the insert rod 205 is always pressed against the fixing block 208, thus preventing the insert rod 205 from falling off during the support operation. During the process of compacting the plastic bottle, the moisture in the bottle material will overflow from the bottle mouth and fall into the collection box 105 after being filtered by the filter plate 311. When the worm gear 201 is rotated, the rotation of the worm gear 201 will drive the worm wheel 202 to rotate, causing the rotating shaft 102 to rotate on the fixing frame 101, which in turn will drive the fixing frame 103 to rotate as a whole, so that the pressure plate 203 is no longer in the placement box 1. Directly above, the compacted plastic bottle can now be demolded normally. The second motor 306 is started. The rotation of the second motor 306 drives the left-side bidirectional threaded rod 307 to rotate, causing the pulley 308 on the left-side bidirectional threaded rod 307 to rotate. The rotation of the pulley 308 drives the belt 309 to rotate, causing the right-side bidirectional threaded rod 307 to rotate. The simultaneous rotation of multiple bidirectional threaded rods 307 drives multiple sliders 310 to slide simultaneously towards the center position, thus moving the connecting rod 312. Due to the fixed seat 313 and the limiting shaft 3... 14 limits the movement trajectory of the connecting rod 312. Therefore, when the slider 310 slides towards the center, it will push the filter plate 311 out of the placement box 1 and demold the compacted plastic bottle. When the first motor 301 is started, the rotation of the first motor 301 will drive the transmission shaft 315 to rotate, causing the gear 314 to rotate. The rotation of the gear 314 will simultaneously drive the rack 303 to move towards the center, causing the nail plate 304 to converge towards the center. The nail plate 304 can puncture the plastic bottle and accelerate the outflow of residual water in the bottle.
