Description

Technical Field

[0001] This invention relates to the field of environmental recycling technology, specifically to a carpet backing adhesive separation device. Background Technology

[0002] Carpet recycling is an environmentally friendly practice that helps reduce environmental pollution from landfills and incineration.

[0003] In existing processing methods, using recycled carpets for processing is relatively inexpensive and the performance difference compared to virgin materials is small. Therefore, producing carpet adhesive by dismantling old carpets to replace some raw materials is a more economical method. However, carpet adhesive removal is a relatively complex process that requires the correct methods and tools to ensure efficiency and safety. With existing equipment, some carpet adhesive tends to adhere to the carpet surface, and during the removal process, carpet fibers can easily get mixed into the removed adhesive, requiring secondary cleaning. Therefore, we propose a carpet adhesive removal and separation device to solve these problems. Summary of the Invention

[0004] The purpose of this invention is to provide a backing adhesive separation device for carpet recycling, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a carpet recycling adhesive removal and separation device, comprising a transmission base, a cleaning tank located inside the transmission base, and a rectangular frame installed on the top of the transmission base. The top of the transmission base is provided with multiple support pads, the rectangular frame is installed on the top of the support pads, a limiting frame is installed on the top of the rectangular frame, the limiting frame is located in the middle section of the rectangular frame, a pair of auxiliary transmission mechanisms are provided on the top of the limiting frame, and a pair of peeling mechanisms are provided at the bottom of the limiting frame.

[0006] The cleaning tank has multiple snap-fit ​​slots installed on its side wall, and a separation box is installed inside each snap-fit ​​slot. One end of each separation box has a drain hole, which is connected to external equipment. Multiple guide shafts are installed inside the cleaning tank. The guide shafts are staggered with the snap-fit ​​slots and are symmetrically arranged inside the cleaning tank. A sponge plate can be snapped onto the top of a pair of guide shafts. When it is necessary to peel off the plastic layer of the carpet, an agent that softens the carpet adhesive can be mixed into the cleaning tank. As the external equipment pulls the carpet inside the cleaning tank, the carpet adhesive softens after soaking. During the transmission process, with the cooperation of the auxiliary transmission mechanism and the peeling mechanism, the excess carpet adhesive on the surface can be quickly peeled off and separated, facilitating subsequent separation and recycling.

[0007] Preferably, the limiting frame has a pair of sliding grooves, and a sliding rod is movably engaged inside the sliding grooves. Metal plates are evenly installed at the bottom of the sliding rods, and pneumatic shafts are engaged on the outside of the metal plates. Multiple reset balls are arranged between the pneumatic shafts, and elastic levers are installed at both ends of the reset balls. Multiple through holes are opened on the metal plates, and the pneumatic shafts are connected to the elastic levers passing through the through holes. A pair of limiting plates are installed at the bottom of the limiting frame, and the peeling mechanism is arranged between the limiting plates. The peeling mechanism can move between the limiting plates and can quickly peel off the carpet adhesive, reducing the possibility of carpet adhesive residue.

[0008] Preferably, the auxiliary transmission mechanism includes multiple limiting shafts, which are arranged in a uniform array at the top of the limiting frame. The limiting shafts are hollow inside, and a tension rod is movably engaged inside the multiple limiting shafts.

[0009] One end of the tension rod is fixedly connected to an elastic pull rope, which is also clamped on the outer wall of one end of the sliding rod. The auxiliary transmission mechanisms at both ends are respectively connected to the sliding rods on both sides. During the carpet transmission process, the tension rod is compressed and stretched. While tensioning the carpet, it can also drive the change of air pressure inside the air pressure shaft with the help of the elastic pull rope.

[0010] Preferably, a connecting frame is installed on the outer wall of the tension rod, and a transmission roller is rotatably provided at one end of the connecting frame. The transmission roller has multiple protrusions on its surface, and the protrusions are triangular in shape. The transmission roller, in conjunction with the tension rod, can stretch and tension the carpet. During the transmission process, the protrusions on the surface of the transmission roller can be used to comb the carpet surface and separate excess debris and impurities.

[0011] Preferably, the peeling mechanism includes a drive shaft, which is movably engaged between the limiting plates. The drive shaft is symmetrically arranged at the bottom of the limiting frame. A positioning tube is sleeved on the surface of the drive shaft. Multiple push shafts are installed at the bottom of the positioning tube, and one end of the push shaft is arc-shaped and abuts against the outer wall of the pneumatic shaft. The push shaft can follow the deformation of the pneumatic shaft itself to drive the drive shaft to move, thereby enabling the peeling mechanism to operate and treat the carpet adhesive.

[0012] Preferably, metal shafts are installed at both ends of the bottom of the positioning tube, and support plates are installed at the bottom of the metal shafts. The support plates are continuously bent and made of shape memory metal. Multiple fixing frames are installed at the bottom of the support plates, and multiple transmission rollers are rotatably arranged on the bottom of the fixing frames. The transmission rollers are arranged in a uniform array on the fixing frames, and multiple peeling shafts are installed between the transmission rollers. Multiple inclined metal plates are installed on the surface of the peeling shafts for peeling and recycling carpet adhesive. The carpet adhesive can be torn and separated from multiple angles to prevent excess carpet adhesive from adhering to the base fabric layer.

[0013] Preferably, a compression tube is installed at the bottom of the separation box, and a reset rope is provided inside the compression tube. The reset rope is installed between the separation boxes. The reset rope is elastic and has a suspension block installed at the top. Multiple guide rings are clamped on the surface of the reset rope. Multiple vertical grooves are opened on the guide rings. A separation disc is installed on the outer wall of the guide ring. The separation disc is inclined and made of mesh material, which can limit and collect the carpet adhesive that has been crushed into particles during sewage discharge, and prevent it from accumulating on one side of the drain hole.

[0014] Preferably, the top of the rectangular frame is provided with a pair of straight grooves, and each straight groove is provided with a movable roller. The movable roller is used for carpet conveying, reducing the friction pressure on the carpet during the conveying process and reducing the dust flying during the feeding process.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. During the carpet transfer process, this invention enables one side of the carpet adhesive to abut against the bottom of the support plate. Simultaneously, as the sliding rod moves with the tension rod, the metal plate can move. The pneumatic shaft can deform under the pulling action of the elastic lever. The push shaft can move the transmission shafts on both sides. Force can be applied from the vertical direction of carpet transfer to peel off excess carpet adhesive from the surface.

[0017] 2. During the transmission process, the present invention enables one side of the carpet pile to adhere to the transmission roller. As the carpet is transmitted, it can pull the tension rod to move inside the limiting shaft, which can tension the carpet during the transmission process, ensuring that the agent is soaked evenly and also facilitating the subsequent degumming and peeling.

[0018] 3. The present invention allows the carpet pile to come into contact with the conveyor roller. During the conveying process, the protrusions can be used to comb the pile and pre-treat dirt and other contaminants adhering to the inside, making it easier to adjust and clean later.

[0019] 4. During the movement of the support plate, the present invention can swing under its own action, and with the help of the water flow inside the cleaning tank, it can follow the flow of the support plate to disperse the carpet adhesive accumulated around the transmission roller and make it deposit at the bottom of the cleaning tank.

[0020] 5. After the carpet adhesive is peeled off, the present invention can drain the water inside the cleaning tank, and the carpet adhesive can be transferred to the separation discs under the action of water flow. After the liquid level drops, the reset rope can be reset, and multiple separation discs can be stacked. Excess water inside can be discharged into the compression pipe along the guide ring for unified collection, preventing small carpet adhesive fragments from getting stuck in the drain hole along the water flow and reducing the occurrence of blockage.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figures 1-7 The present invention provides a technical solution: a carpet recycling adhesive removal and separation device, including a transmission base 1, a cleaning box 11 located inside the transmission base 1, and a rectangular frame 12 installed on the top of the transmission base 1. Multiple support pads are installed on the top of the transmission base 1, the rectangular frame 12 is installed on the top of the support pads, a limit frame 2 is installed on the top of the rectangular frame 12, the limit frame 2 is located in the middle section of the rectangular frame 12, a pair of auxiliary transmission mechanisms 3 are provided on the top of the limit frame 2, and a pair of peeling mechanisms 5 are provided on the bottom of the limit frame 2.

[0031] Multiple snap-fit ​​slots are installed on the side wall of the cleaning tank 11, and a separation box 4 is snapped into the slot. One end of the separation box 4 has a drain hole, which is connected to external equipment. Multiple guide shafts 14 are installed inside the cleaning tank 11. The guide shafts 14 are staggered with the snap-fit ​​slots and symmetrically arranged inside the cleaning tank 11. A sponge plate can be snapped into the top of a pair of guide shafts 14. The sponge plate can absorb dirt and debris suspended on the water surface, preventing dust and other debris accumulated on the carpet surface from floating on the water surface and making it difficult to observe the carpet adhesive peeling. When it is necessary to peel off the plastic layer of the carpet, an agent that softens the carpet adhesive can be mixed into the cleaning tank 11. As the external equipment pulls the carpet inside the cleaning tank 11, the carpet adhesive softens after soaking. During the transmission process, with the cooperation of the auxiliary transmission mechanism 3 and the peeling mechanism 5, the excess carpet adhesive on the surface can be quickly peeled off and separated, which is convenient for subsequent separation and recycling.

[0032] like Figure 6 As shown, to prevent the carpet from becoming too tight or loose during transmission, the limiting frame 2 is provided with a pair of sliding grooves, and a sliding rod 21 is movably engaged inside the sliding grooves. Metal plates are evenly installed at the bottom of the sliding rod 21, and a pneumatic shaft 23 is engaged on the outside of the metal plate. Multiple reset balls 24 are provided between the pneumatic shafts 23, and elastic levers are installed at both ends of the reset balls 24. Multiple through holes are provided on the metal plate, and the pneumatic shafts 23 are connected to the elastic levers passing through the through holes. A pair of limiting plates 22 are installed at the bottom of the limiting frame 2, and the peeling mechanism 5 is set between the limiting plates 22. The sliding rod 21 can stretch the transmission roller 33 with the help of the elastic pull rope, thereby stretching and stretching the carpet during transmission. This allows the softening agent to penetrate quickly and also reduces the risk of the carpet shifting or other unexpected situations during transmission.

[0033] like Figure 2 As shown, the carpet is prone to shifting during the transmission process. The auxiliary transmission mechanism 3 includes multiple limiting shafts 31. The limiting shafts 31 are arranged in a uniform array at the top of the limiting frame 2. The inside of the limiting shafts 31 is hollow. Tension rods 32 are movably locked inside the multiple limiting shafts 31.

[0034] One end of the tension rod 32 is fixedly connected to an elastic pull rope, which is clamped on the outer wall of one end of the sliding rod 21. The auxiliary transmission mechanisms 3 at both ends are connected to the sliding rods 21 on both sides respectively. The auxiliary transmission mechanisms 3 can adjust the tension of the carpet by means of the elastic pull rope, which can reduce the accidental cleaning of carpet transmission jamming and further ensure the processing efficiency of the equipment.

[0035] like Figure 3As shown, various impurities and debris are easily mixed in the carpet pile, and they tend to float on the water surface during the transmission process. A connecting frame is installed on the outer wall of the tension rod 32, and a transmission roller 33 is rotatably installed at one end of the connecting frame. The transmission roller 33 has multiple protrusions on its surface, and the protrusions are triangular in shape. The transmission roller 33, together with the tension rod 32, can stretch and tension the carpet. During the transmission process, the protrusions on the surface of the transmission roller 33 and the carpet pile are staggered, which can play a combing role during the transmission process, and quickly peel off the debris mixed on the carpet surface.

[0036] like Figure 6 As shown, in order to reduce carpet adhesive residue during transmission, the peeling mechanism 5 includes a drive shaft 51. The drive shaft 51 is movably locked between the limiting plates 22. The drive shaft 51 is symmetrically arranged at the bottom of the limiting frame 2. A positioning tube 52 is sleeved on the surface of the drive shaft 51. Multiple push shafts are installed at the bottom of the positioning tube 52. One end of the push shaft is arc-shaped and abuts against the outer wall of the pneumatic shaft 23. The pneumatic shaft 23 can deform under the pulling action of the elastic lever. It can move the drive shafts 51 on both sides with the help of the push shafts, and can apply force from the vertical direction of carpet transmission to peel off the excess carpet adhesive on the surface.

[0037] like Figure 7 As shown, to prevent a small amount of carpet adhesive residue from remaining during the peeling process, metal shafts are installed at both ends of the bottom of the positioning tube 52, and support plates 53 are installed at the bottom of the metal shafts. The support plates 53 are continuously bent and made of shape memory metal. Multiple fixing frames 54 are installed at the bottom of the support plates 53, and multiple transmission rollers 55 are rotatably mounted on the bottom of the fixing frames 54. The transmission rollers 55 are evenly arrayed on the fixing frames 54, and multiple peeling shafts 551 are installed between the transmission rollers 55. Multiple inclined metal plates are installed on the surface of the peeling shafts 551 for peeling and recycling the carpet adhesive. During the movement of the support plate 53, it can swing under its own action and can follow the flow of water inside the cleaning tank 11 to disperse the carpet adhesive accumulated around the transmission rollers 55 and deposit it at the bottom of the cleaning tank 11, which can ensure the carpet adhesive peeling efficiency during the transmission process.

[0038] like Figure 5As shown, to prevent the carpet adhesive from accumulating and clogging after peeling, a compression pipe 41 is installed at the bottom of the separation box 4. A reset rope 42 is installed inside the compression pipe 41 and is installed between the separation boxes 4. The reset rope 42 is elastic and has a suspension block installed at its top. Multiple guide rings 44 are clamped onto the surface of the reset rope 42, and multiple vertical grooves are opened on the guide rings 44. A separation disc 43 is installed on the outer wall of the guide rings 44. The separation disc 43 is inclined and made of mesh material. After the carpet adhesive is peeled off, the water inside the cleaning tank 11 can be drained out, and the carpet adhesive can be transferred to the separation discs 43 by the water flow. After the liquid level drops, the reset rope 42 can be reset, allowing the multiple separation discs 43 to be stacked. Excess water and other debris are discharged along the guide rings 44 into the compression pipe 41 for unified collection, preventing small particles and debris from getting stuck in the drain hole, reducing clogging, ensuring smooth sewage drainage, and extending the equipment maintenance cycle.

[0039] To ensure the stability of the equipment transmission, a pair of straight grooves are provided at the top of the rectangular frame 12, and movable rollers 13 are rotatably installed inside the straight grooves. The movable rollers 13 are used for carpet transmission.

[0040] Working principle: First, when it is necessary to peel off the plastic layer of the carpet, the cleaning tank 11 can be mixed with a carpet adhesive softening agent. As the external equipment pulls the carpet inside the cleaning tank 11, the carpet adhesive softens after soaking. During the transmission process, with the cooperation of the auxiliary transmission mechanism 3 and the peeling mechanism 5, the excess carpet adhesive on the surface can be quickly peeled off and separated, which is convenient for subsequent separation and recycling. During the transmission process, one side of the carpet pile can be attached to the transmission roller 33. During the transmission process, the carpet can pull the tension rod 32 to move inside the limit shaft 31, which can tension the carpet during the transmission process, ensuring that the agent is soaked evenly and also facilitating the subsequent degumming. During the transmission process, the carpet pile can abut against the transmission roller 33. During the transmission process, the protrusions can be used to comb the pile surface and pre-treat the dirt and other dirt adhering inside, which is convenient for subsequent adjustment and cleaning.

[0041] Then, during the carpet transfer process, one side of the carpet adhesive can be made to abut against the bottom of the support plate 53. At the same time, when the sliding rod 21 moves with the tension rod 32, the metal plate can move. The pneumatic shaft 23 can deform under the pulling action of the elastic lever. It can move the two drive shafts 51 by means of the push shaft. It can apply force from the vertical direction of carpet transfer to peel off the excess carpet adhesive on the surface. As the support plate 53 moves, it can swing under its own action. It can use the water flow inside the cleaning tank 11 to follow the support plate 53 to disperse the carpet adhesive accumulated around the drive roller 55 and make it deposit at the bottom of the cleaning tank 11.

[0042] Finally, after the carpet adhesive is removed, the water inside the cleaning tank 11 can be drained, and the carpet adhesive can be transferred to the separation discs 43 by the water flow. After the liquid level drops, the reset rope 42 can be reset, and the multiple separation discs 43 can be stacked. Excess water inside can be discharged into the compression pipe 41 along the guide ring 44 for unified collection, preventing small particles and debris from getting stuck in the drain hole along the water flow and reducing the occurrence of blockages.

[0043] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
