Description

Technical Field

[0001] This utility model relates to the field of foam board crushing technology, specifically to a crushing device for foam board recycling. Background Technology

[0002] Foam boards, especially polystyrene foam boards (also known as EPS boards), are widely used in building walls, roof insulation, composite board insulation, cold storage, air conditioning, vehicle and ship insulation, floor heating, and decorative carving due to their micro-closed-cell structure. With the large-scale use of foam boards, the amount of waste foam board strips and scraps has also increased. If these wastes are not properly disposed of, they will not only occupy space but may also pollute the environment. Therefore, crushing devices use specific crushing mechanisms (such as blades and rollers) to cut foam boards into smaller fragments to facilitate subsequent collection, transportation, and processing.

[0003] Existing foam boards, due to their lightweight nature, may deviate during the crushing process with minimal resistance, resulting in incomplete crushing. For example, a foam board crushing device disclosed in patent CN208484076U has an open feed inlet. This open feed inlet not only fails to effectively guide and position the foam board, leading to incomplete crushing, but also makes it easier for dust and exhaust gases generated during the crushing process to escape, causing environmental pollution.

[0004] Therefore, it is necessary to invent a crushing device for recycling foam boards to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a crushing device for recycling foam boards, in order to solve the problems in the technology where the open-structure feed inlet not only fails to effectively guide and position the foam boards, resulting in incomplete crushing, but also allows dust and exhaust gas generated during the crushing process to escape more easily, causing environmental pollution.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a crushing device for recycling foam board, comprising a support platform, a crushing box, and a feeding pipe. The crushing box is arranged on one side above the support platform, and a feeding box is arranged above the crushing box. A first crushing roller and a second crushing roller are arranged inside the crushing box. An electric push rod is arranged on the outer top surface of the feeding box. A pressure block is arranged at the inner top of the feeding box. The top surface of the pressure block is connected to the output end of the electric push rod. A feeding pipe is arranged at the bottom end of the crushing box. An anti-stick coating is arranged on the inner wall of the feeding pipe, and a vibration motor is arranged on the bottom surface of the outer wall of the feeding pipe.

[0007] Preferably, the discharge end of the feeding box is connected to the feed end of the crushing box, and a door is hinged to the front of the feeding box to ensure that the material can smoothly enter the crushing box.

[0008] Preferably, the surface of the box door is provided with a transparent glass observation window, which allows the operator to observe the condition of the internal foam board from the outside of the feeding box.

[0009] Preferably, one end of the first and second crushing rollers is rotatably connected to the inner wall of the crushing chamber, and the other end of the first and second crushing rollers extends through to the outside of the crushing chamber, ensuring that the first and second crushing rollers can rotate freely inside the crushing chamber, thereby realizing the crushing function of the foam board.

[0010] Preferably, a sidewall toothed plate is provided on one side of both the first and second crushing rollers. The sidewall toothed plate is located on the inner wall of the crushing box. The sidewall toothed plate is coordinated with the tooth grooves of the first and second crushing rollers in position. The tooth grooves of the first and second crushing rollers will interact with the sidewall toothed plate, thereby crushing the foam board more finely.

[0011] Preferably, one end of the first crushing roller is provided with a first gear, and one end of the second crushing roller is provided with a second gear. The first gear and the second gear mesh with each other. Through the meshing of the first gear and the second gear, it can be ensured that the two crushing rollers rotate at the same speed and direction, thereby maintaining the consistency and stability of the crushing process.

[0012] Preferably, a drive motor is provided on one side of the crushing box and located on a support platform. A divider is provided on one side of the drive motor. The output end of the drive motor is connected to the input end of the divider. The output end of the divider is connected to a connecting rod, which is connected to a second gear. The drive motor is connected to the second gear through the divider and the connecting rod. This design can precisely control the speed and torque of the crushing roller, thereby meeting different crushing needs.

[0013] Preferably, the pressing block is located inside the feed box and is positioned directly above the first and second crushing rollers. The pressing block pre-compresses and guides the foam board entering the crushing box.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] 1. This utility model achieves the function of pre-compressing foam boards entering the crushing box through the electric push rod driven pressure block design. When the foam board is fed into the feeding box, the pressure block will press down in time, so that the foam board can make more compact contact and enter the crushing area. This design not only helps to prevent the foam board from shifting or getting stuck due to looseness during the crushing process, but also improves the crushing efficiency and quality. At the same time, the guiding effect of the pressure block ensures that the foam board can accurately enter the gap between the crushing rollers, further ensuring the consistency and stability of crushing.

[0016] 2. This utility model effectively solves the problem of foam board easily adhering to the inner wall of the feeding pipe after being crushed by setting an anti-stick coating on the inner wall of the feeding pipe, thereby avoiding the occurrence of poor discharge or blockage. In addition, the vibration motor set on the bottom surface of the outer wall of the feeding pipe further promotes the smooth discharge of the crushed foam board through vibration. This design not only improves the discharge efficiency, but also reduces the maintenance workload of operators and enhances the practicality and reliability of the device.

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] This utility model provides, for example Figure 1-5The shown is a foam board recycling crushing device, including a support platform 1, a crushing box 2, and a feeding pipe 15. The crushing box 2 is arranged on one side above the support platform 1, and a feeding box 3 is arranged above the crushing box 2. The crushing box 2 is equipped with a first crushing roller 5 and a second crushing roller 6. An electric push rod 13 is arranged on the top surface of the outside of the feeding box 3. A pressure block 14 is arranged at the top inside the feeding box 3. The top surface of the pressure block 14 is connected to the output end of the electric push rod 13. The pressure block 14 is located inside the feeding box 3 and is positioned directly above the first crushing roller 5 and the second crushing roller 6. The feeding pipe 15 is arranged at the bottom of the crushing box 2. The inner wall of the feeding pipe 15 is equipped with an anti-stick coating 16, and a vibration motor 17 is arranged on the bottom surface of the outer wall of the feeding pipe 15.

[0026] The electric push rod 13 drives the pressure block 14 to pre-compress the foam board entering the crushing box 2, making it more compact as it enters the crushing area. This helps prevent the foam board from shifting or getting stuck during the crushing process, thereby improving crushing efficiency and quality. In addition, the anti-stick coating 16 on the inner wall of the feed pipe 15 effectively solves the problem of foam board sticking after crushing, avoiding poor discharge or blockage. Furthermore, the vibration motor 17 further promotes the smooth discharge of the crushed foam board, improving discharge efficiency.

[0027] The discharge end of the feed box 3 is connected to the feed end of the crushing box 2. A door 4 is hinged to the front of the feed box 3, and a transparent glass observation window is provided on the surface of the door 4. One end of the first crushing roller 5 and the second crushing roller 6 is rotatably connected to the inner wall of the crushing box 2, and the other end extends through to the outside of the crushing box 2. A sidewall toothed plate 7 is provided on one side of each of the first and second crushing rollers 5 and 6. The sidewall toothed plate 7 is located on the inner wall of the crushing box 2, and the sidewall toothed plate 7 is connected to the first crushing roller 5 and the second crushing roller 6. The tooth grooves of the first crushing roller 6 are coordinated in position. One end of the first crushing roller 5 is provided with a first gear 8, and one end of the second crushing roller 6 is provided with a second gear 9. The first gear 8 and the second gear 9 mesh with each other. A drive motor 10 is provided on one side of the crushing box 2 and is located on the support platform 1. A divider 11 is provided on one side of the drive motor 10. The output end of the drive motor 10 is connected to the input end of the divider 11. The output end of the divider 11 is connected to a connecting rod 12, which is connected to the second gear 9.

[0028] The toothed plate 7 on the side wall is positioned in coordination with the tooth grooves of the first crushing roller 5 and the second crushing roller 6. The two interact with each other to crush the foam board more finely. Furthermore, the meshing of the first gear 8 and the second gear 9 ensures that the first crushing roller 5 and the second crushing roller 6 can rotate at the same speed and direction, thereby maintaining the consistency and stability of the crushing process, achieving fine crushing of the foam board and improving the crushing effect.

[0029] Working principle of this utility model:

[0030] Refer to the instruction manual appendix Figure 1-4 When using this invention, first open the front door 4 of the feed box 3 to prepare to put in the foam board. Place the foam board to be crushed into the feed box 3, ensuring the feed box 3 is sealed. Then start the electric push rod 13. The output end of the electric push rod 13 pushes the pressure block 14 downward to pre-compress the foam board. Pre-compression makes the foam board enter the crushing area more compactly, preventing it from shifting or getting stuck due to looseness during the crushing process. With the electric push rod 13 continuously pushing (or after the pre-compression is completed and the electric push rod 13 stops, but the pressure block 14 maintains pressure on the foam board), then... Then, the drive motor 10 is started. The drive motor 10 drives the second gear 9 to rotate through the divider 11 and the connecting rod 12. Since the first gear 8 meshes with the second gear 9, the first crushing roller 5 and the second crushing roller 6 will also start to rotate at the same speed and direction. The foam board enters the gap between the first crushing roller 5 and the second crushing roller 6 under the guidance of the pressure block 14. It is crushed by the squeezing and shearing action of the two. At the same time, the side wall toothed plate 7 interacts with the tooth grooves of the first crushing roller and the second crushing roller 6 to crush the foam board more finely.

[0031] Refer to the instruction manual appendix Figure 5 When using this utility model, the crushed foam board is discharged through the feed pipe 15 at the bottom of the crushing box 2. The anti-stick coating 16 on the inner wall of the feed pipe 15 effectively prevents the crushed foam board from adhering to the inner wall, avoiding the occurrence of poor discharge or blockage. At the same time, the vibration of the vibration motor 17 further promotes the smooth discharge of the crushed foam board and improves the discharge efficiency.
