Description

Technical Field

[0001] This utility model relates to the field of polystyrene recycling technology, specifically a polystyrene recycling and compression block device with cleaning function. Background Technology

[0002] For polystyrene foam sheets, some are directly fed into specially designed recycling machines. These recycling machines usually have a large feed inlet to allow larger sheets to be fed in directly. They are equipped with rotating cutters that can cut, compress, and heat the softer polystyrene foam sheets to melt them and then extrude strips with a certain density.

[0003] Existing polystyrene needs to be crushed before it can be recycled and processed. Then it is pressed into blocks by compression molding equipment for easy transportation. However, the friction of the material during the compression process generates heat, which causes some waste to remain on the inner wall of the equipment. Utility Model Content

[0004] The purpose of this invention is to provide a polystyrene recycling and compression block device with a cleaning function. It uses the inevitable return motion of the pressure plate as a power source, eliminating the need for an additional independent cleaning drive device or process. After each compression, the pressure plate rises and automatically triggers the scraper to perform full-stroke and no-dead-angle scraping and cleaning of the inner wall of the molding frame, which can solve the problems in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a polystyrene recycling and compression block device with cleaning function, comprising a pressing box, an unloading box door on the outer surface of the pressing box, an loading box door above the unloading box door, a molding cavity inside the pressing box, a molding frame inside the molding cavity, a support plate below the molding frame, a slide rail below the support plate, and the support plate connected to the pressing box via the slide rail.

[0006] With the above solution, the pallet is located directly below the forming frame, initially at the bottom of the forming cavity, bearing the weight of the waste and the forming frame. The pallet is connected to the pressing box via a slide rail at its bottom, providing a smooth sliding path for its subsequent exit action.

[0007] Preferably, a limit buckle is provided on the inner side of the unloading box door, and the limit buckle is rotatably connected to the unloading box door.

[0008] With the above solution, the limit buckle is set inside the unloading box door. Its rotating connection design allows the limit buckle to lock onto the corresponding structure on the molding frame or pallet when the box door is closed, ensuring that the position of the entire molding unit is stable during compression and will not shift due to high pressure. When unloading is required, the limit buckle can be unlocked by rotating it.

[0009] Preferably, a pressure plate is provided above the molding frame, and a lifting rail is provided on the back of the pressing box, with the lifting rail extending into the interior of the molding cavity.

[0010] Preferably, one side of the forming frame is provided with an integrally formed hanging shaft, and the forming frame is connected to the slide rail through the hanging shaft.

[0011] Preferably, a hydraulic assembly is provided above the pressure plate, and guide rods are provided on both sides of the hydraulic assembly, wherein the guide rods and the hydraulic assembly are installed on the top of the pressing box.

[0012] Preferably, trusses are provided on both sides of the pressure plate, and rubber plate buckles are provided at both ends of the trusses. A scraper is provided between the rubber plate buckles, and the scraper is in contact with the inner side of the forming frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model utilizes the inevitable return motion of the pressure plate as a power source, eliminating the need for additional independent cleaning drive devices or processes. Moreover, after each compression, the pressure plate rises and automatically triggers the scraper to perform full-stroke and no-dead-angle scraping and cleaning of the inner wall of the molding frame, fundamentally solving the industry problem of polystyrene softening and sticking to the wall under high-pressure friction, ensuring that the inner wall of the molding cavity is clean before each compression.

[0015] 2. In this utility model, the scraper is rigidly connected to the pressure plate through a truss and a rubber plate buckle, while also having a certain degree of flexibility. This ensures that the scraper can closely fit the inner wall and move synchronously with the pressure plate. The structure is simple and reliable. The design of the rubber plate buckle not only provides convenient installation, but its elasticity can also play a buffering role during the scraping process, absorbing possible minor impacts or unevenness, protecting the scraper and the inner wall of the forming frame, extending their service life, and ensuring the scraping effect.

[0020] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] To address the issue that existing methods of recycling polystyrene require crushing before compression molding for easy transport, but this process generates heat through friction, resulting in some waste material remaining on the inner walls of the equipment; please refer to... Figure 1-3 The present invention provides the following solution:

[0022] A polystyrene recycling and compression block device with cleaning function includes a pressing box 1. The outer surface of the pressing box 1 is provided with a discharge box door 101. A feeding box door 102 is provided above the discharge box door 101. The inside of the pressing box 1 is provided with a molding cavity 103. The inside of the molding cavity 103 is provided with a molding frame 3. A support plate 104 is provided below the molding frame 3. A slide rail 1041 is provided below the support plate 104. The support plate 104 is connected to the pressing box 1 through the slide rail 1041. A limit buckle 1011 is provided on the inner side of the discharge box door 101. The limit buckle 1011 is rotatably connected to the discharge box door 101. A pressure plate 2 is provided above the molding frame 3. A lifting rail 105 is provided on the back of the pressing box 1. The lifting rail 105 extends into the inside of the molding cavity 103.

[0023] In this embodiment, the feeding box door 102 is opened, and the pre-crushed polystyrene foam waste is fed into the molding cavity 103. The waste naturally falls into and accumulates inside the molding frame 3. The feeding box door 102 is closed, and the hydraulic component 201 is activated, driving the pressure plate 2 to move vertically downward along the lifting track 105. The lifting track 105 passes through the top of the pressing box 1 and extends into the molding cavity 103, ensuring that the movement of the pressure plate 2 is precise, stable, and perpendicular to the support plate 104. The guide rods 202 on both sides are connected to the pressure plate 2, further constraining the movement trajectory of the pressure plate 2, preventing it from deviating under high pressure, and ensuring the uniform application of compression force. The pressure plate 2 forcefully presses down on the loose polystyrene waste in the molding frame 3. Under the action of huge pressure, the waste particles are tightly compressed, deformed, and interlocked, and the volume shrinks sharply. Finally, under the constraint of the molding frame 3, a dense and regular cuboid is formed.

[0024] One side of the forming frame 3 is provided with an integrally formed hanging shaft 301. The forming frame 3 is connected to the slide rail 1041 through the hanging shaft 301. A hydraulic component 201 is provided above the pressure plate 2. Guide rods 202 are provided on both sides of the hydraulic component 201. The guide rods 202 and the hydraulic component 201 are installed on the top of the pressing box 1. Trusses 203 are provided on both sides of the pressure plate 2. Rubber plate buckles 204 are provided at both ends of the trusses 203. A scraper 205 is provided between the rubber plate buckles 204. The scraper 205 is attached to the inner side of the forming frame 3.

[0025] In this embodiment, as the pressure plate 2 is lifted upwards, the scraper 205 fixed to the trusses 203 on both sides of the pressure plate 2 rises synchronously. The scraper 205 is flexibly and firmly installed on the trusses 203 by the rubber clips 204 at both ends. The design of the scraper 205 ensures that its edges are in close contact with the inner wall of the molding frame 3. As the pressure plate 2 and the trusses 203 rise, the scraper 205 acts like an inner wall cleaner, scraping at a uniform speed from bottom to top along the inner wall of the molding frame 3. This process thoroughly scrapes off the polystyrene residue that has softened, melted, and adhered to the inner wall of the molding frame 3 due to frictional heat during compression.
