Description

Technical Field

[0001] The invention relates to the technical field of thermal insulation cotton recycling, and in particular to a thermal insulation cotton board waste recycling and processing device. Background Art

[0002] Common materials for automotive interior insulation layers or thermal insulation cotton need to meet a variety of performance requirements, including good thermal insulation, lightweight, fire retardant, low volatile organic compound (VOC) emissions and cost-effectiveness. For example, polyurethane (PU) foam has excellent thermal insulation and sound insulation, low density and easy molding, and is widely used in car doors, the back of the dashboard and under the floor; polypropylene (PP) non-woven fabrics are used to make seat copies, headrests and other fillings in interior parts; PET polyester fiber is used as a carpet backing and a supporting material behind the door trim.

[0003] In the production process of automotive insulation wool boards, a certain amount of waste may be generated in the cutting, forming and packaging stages. For example, when a large piece of insulation wool board raw material is cut into a shape and size suitable for vehicle use, scraps will be generated at the edges.

[0004] The Chinese patent application number 202310830269.1 discloses a waste recycling device for rock wool insulation board production. It includes a crushing body, a screening mechanism and a compression molding mechanism. The screening mechanism is arranged at the bottom of the crushing body, the compression molding mechanism is arranged at the bottom of the screening mechanism, and the inner cavity of the crushing mechanism is provided with a first-level crushing mechanism. The above application achieves the technical effect of fully crushing the rock wool waste by operating two-stage crushing devices at the same time, and solves the technical problem of insufficient crushing in the prior art. However, the following problems still exist:

[0005] In the process of recycling these waste materials, the use of claw-knife pulverizers can effectively prevent the waste materials from being entangled on the pulverizing shaft. However, since polyurethane (PU) insulation cotton is a thermoplastic elastomer, it will become soft or even melt at higher temperatures. The friction heat generated when the pulverizer is working causes the local temperature of the PU insulation cotton to rise, causing it to soften and adhere to the pulverizing knife. At the same time, although polypropylene (PP) spunbond non-woven fabrics and PET polyester have higher melting points, under the condition of high-speed rotation or strong friction, if the equipment lacks an effective cooling system, local overheating may still occur, causing the insulation cotton to melt and adhere to the surface of the blade. Therefore, a large amount of waste often adheres to the blade during the pulverization process, especially when the pulverizer is processing a large amount of waste. Due to the large amount of pulverization and the long operation time of the equipment, the phenomenon of "sticking to the blade" becomes more and more obvious; after pulverization, workers need to clean the blade, which is not only very troublesome, but also requires special equipment or greater force to completely remove it due to the strong adhesion during the cleaning process.

[0006] To this end, the present invention proposes a device for recycling and processing waste insulation cotton boards to solve the above problems. Summary of the invention

[0018] The beneficial effects of the present invention are:

[0019] 1. The present invention is provided with a connecting tube, an air groove and a flow channel. During the pulverizing process of the pulverizer, after the air supply device is started, the air supply device can pass the external air into the interior of the pulverizer, and the gas ejected from the first air hole can not only cool the blade, but also clean the waste adhered to the blade; at the same time, since the inner diameter of the first air hole is smaller than the diameter of the flow channel and the connecting groove, the initial velocity of the gas ejection is relatively large, and the cleaning effect on the blade is stronger; it avoids waiting until the pulverizing is completed to clean the blade, because the waste is highly sticky to the blade, and the worker needs to use greater force or special tools to clean it, thereby reducing the cleaning workload.

[0020] 2. The present invention extends the gas ejected from the first air hole by means of the connection strip, the cleaning plate, the through groove and the second air hole, so that the second air hole is closer to the blade, the amount of gas escape is reduced, and most of the gas can directly act on the cutting edge of the blade, thereby improving the cleaning effect and cooling effect of the gas on the blade.

[0021] 3. The present invention limits the direction of gas cleaning by means of the arrangement of a fixing frame, a connecting tube and an air groove. When the blade passes through the screen area, the ejected gas can clean the flocs on the screen due to static adsorption, and the gas is only ejected in the area passing through the screen, so that the cleaned waste falls onto the screen. This also avoids the problem of large dust in the feed port due to the large amount of gas ejected when the blade passes through the direction of the feed port.

[0022] 4. The present invention is provided with a cover plate, an electromagnetic control component, a pressure relief groove and a sealing plate. For large quantities of waste materials that are easy to stick to the blade, the worker operates the control box to reduce the rotation speed of the shaft and operate multiple electromagnetic control components. The hinged rod drives the cover plate to flip and puts the through groove in a sealed state, so that the cleaning plate cleans the blade surface under the action of air pressure, cleans the waste materials that are difficult to remove accumulated on the blade, further improves the cleaning effect of the blade, extends the continuous working time of the pulverizer, and improves the waste recovery efficiency.

[0023] 5. The present invention uses the arrangement of guide plates and pressure relief grooves. During the process of the cleaning plate cleaning the blade, when the cleaning plate moves to a certain distance, the pressure relief groove is connected with the cavity and releases a large amount of gas. Under the guidance of the guide plate, the gas acts on the blade surface of the cleaning plate again to clean the blade surface of the cleaning plate. In the process of the crushing machine, a pulse cleaning method will be formed to continuously clean the cleaning plate, thereby reducing the workload of workers in subsequent cleaning of the crusher and further increasing the continuous working time of the crusher.

[0047] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0048] Embodiment 1

[0049] In the process of recycling thermal insulation cotton waste, it was found that due to the phenomenon of "sticking to the knife" during the crushing process of polyurethane thermal insulation cotton, polyethylene spunbond non-woven fabric and PET polyester, sometimes when crushing adhesive-backed thermal insulation cotton, although chemical degumming is used for the thermal insulation cotton, there is still some colloid on the surface of the thermal insulation cotton, which will also "stick to the knife" during crushing. When workers crush the thermal insulation cotton, they need to stop the machine to cool down and clean the knife shaft. The process of cleaning the knife shaft requires very strong force or special tools, which is not only time-consuming and labor-intensive, but also affects the recycling efficiency of the thermal insulation cotton. This embodiment is specially invented to solve the above problems.

[0050] See also Figures 1 to 13 As shown, a thermal insulation cotton board waste recycling and processing device of the present invention includes a pulverizer body 1, the pulverizer body 1 includes a support frame 11 and a pulverizer 12 arranged above the support frame 11, the pulverizer 12 includes a shell 121 fixedly connected to the support frame 11, a rotating shaft 122 is rotatably connected to the shell 121, a plurality of equally spaced movable blades 2 are arranged on the rotating shaft 122, and fixed blades 3 matching the movable blades 2 are respectively arranged on the front and rear sides of the shell 121.

[0051] See also Figure 3 , Figure 4 , Figure 6 and Figure 7As shown, the movable knife member 2 includes a knife holder 21 and a plurality of blades 22. The same knife head 23 is arranged at the outer edge of the plurality of knife holders 21. There are a plurality of knife heads 23, which are arranged and distributed circumferentially at the outer edge of the knife holder 21. The plurality of blades 22 are respectively fixedly connected to the corresponding knife heads 23. The rotating shaft 122 is a hollow structure and a connecting cylinder 4 is coaxially arranged inside. The connecting cylinder 4 is a cylindrical structure with one end open, and the open end of the connecting cylinder 4 extends to the outside of the rotating shaft 122 and is externally connected to an air supply device. An air groove 41 is arranged on the connecting cylinder 4. A plurality of flow channels 211 extending to the knife head 23 are provided in the knife holder 21. A plurality of through holes 1221 matching the flow channels 211 are provided on the rotating shaft 122. A connecting groove 212 communicating with the flow channel 211 is provided in the knife head 23. A plurality of first air holes 213 communicating with the connecting groove 212 are provided at the end of the knife head 23.

[0052] See also Figure 1 and, Figure 2 and Figure 4 As shown, a feed port 13 is provided above the crushing member 12, and a driving member located at the rear side of the crushing member 12 is provided on the top of the support frame 11. The driving member includes a motor and a pulley, and the pulley is respectively connected to the rotating shaft 122 and the output end of the motor. A screen 5 located below the moving knife member 2 is fixedly connected to the shell 121, and a crushing chamber 51 is formed between the moving knife member 2 and the screen 5. A discharge port 14 located below the screen 5 is provided on the front side of the support frame 11.

[0053] A control box is arranged on the support frame 11 , a control unit is arranged in the control box, and a collecting box 9 is arranged in the discharge port 14 .

[0054] When in use, a worker starts the driving member through the control box to drive the rotating shaft 122 to rotate, and puts the insulation cotton waste into the feed port 13. As the rotating shaft 122 drives the movable blade 2 to rotate, the waste is crushed under the shearing and squeezing of the movable blade 2 and the fixed blade 3.

[0055] During the crushing process, the air supply device is started through the control box, and the external gas enters the connecting tube 4 through the air supply device and enters the flow channel 211 through the air groove 41 and the through hole 1221, and finally is ejected through the connecting groove 212 to the first air hole 213. During the ejection process, the gas cools down the blade 22 and cleans the waste adhered to the blade 22.

[0056] Through the settings of the connecting tube 4, the air groove 41 and the flow channel 211, during the crushing process of the crusher, after the air supply device is started, the air supply device can pass the external gas into the interior of the crusher, and the gas ejected from the first air hole 213 can not only cool the blade 22, but also clean the waste adhered to the blade 22; at the same time, since the inner diameter of the first air hole 213 is smaller than the diameter of the flow channel 211 and the connecting groove 212, the initial velocity of the gas ejection is relatively large, and the cleaning effect on the blade 22 is stronger.

[0057] Embodiment 2

[0058] In actual use, it was found that the blade 22 was cleaned and cooled only by the gas ejected from the first air hole 213. Since the first air hole 213 is far away from the cutting edge of the blade 22, gas escape is likely to occur during the gas ejection process, causing part of the gas to fail to achieve the corresponding effect. Further improvements are made on the basis of the above embodiment.

[0059] See also Figure 5 , Fig. 9 and Fig.10 As shown, a cleaning assembly 6 is provided on each of the plurality of cutter heads 23, and the cleaning assembly 6 includes a connecting strip 61 fixedly connected to the cutter head 23, the connecting strip 61 and the cutter head 23 form a cavity 62, the first air hole 213 is located in the cavity 62, a cleaning plate 63 is obliquely arranged in the cavity 62, a through groove 631 is provided at one end of the cleaning plate 63 located in the cavity 62, and the other end of the cleaning plate 63 matches the blade of the blade 22 and is provided with a plurality of second air holes 632 connected to the through groove 631.

[0060] On the basis of the above embodiment, during use, when the gas supply device is started, the gas enters the connecting groove 212 along the connecting tube 4, the through hole 1221 and the flow channel 211, and is ejected from the first air hole 213 and then enters the cavity 62. At this time, the gas in the cavity 62 enters the through groove 631 and is ejected from the second air hole 632.

[0061] By means of the connection strip 61, the cleaning plate 63, the through groove 631 and the second air hole 632, the gas ejected from the first air hole 213 is extended so that the second air hole 632 is closer to the blade 22, thereby reducing the amount of gas escape and allowing most of the gas to directly act on the cutting edge of the blade 22, thereby improving the cleaning effect and cooling effect of the gas on the blade 22.

[0062] Embodiment 3

[0063] During the crushing process, the friction between the fibers of the PP spunbond nonwoven fabric and the PET polyester material and the internal components of the crusher will generate static electricity. The generation of static electricity will cause the crushed material to be adsorbed on the inner wall of the crusher or the screen 5, resulting in poor flow of the material; it will not only affect the continuity of the crushing, but also reduce the effective working volume of the equipment. Further improvements are made on the basis of the above embodiment.

[0064] See also Figure 4 As shown, one end of the connecting tube 4 extending to the outside of the rotating shaft 122 is fixedly connected to a fixing frame, and the air groove 41 is opened on a side of the connecting tube 4 close to the screen 5, and the opening angle of the air groove 41 matches the screen 5.

[0065] During use, the fixing frame prevents the connecting cylinder 4 from rotating synchronously with the rotating shaft 122 and keeps the air groove 41 facing the screen 5 at all times. When the air supply device and the grinder body 1 are started, gas will only be ejected from the second air hole 632 when the through hole 1221 is connected to the air groove 41.

[0066] The direction of gas cleaning is restricted by the settings of the fixing frame, the connecting tube 4 and the air groove 41. When the blade 22 passes through the area of ​​the screen 5, the ejected gas can clean the flocs on the screen 5 due to electrostatic adsorption, and the gas is only ejected in the area passing through the screen 5, so that the cleaned waste falls on the screen 5. It also avoids the problem of large dust in the feed port 13 due to the large amount of gas ejected when the blade 22 passes through the direction of the feed port 13.

[0067] Embodiment 4

[0068] For waste materials in large quantities or those that are prone to sticking to the blade, the cleaning of the blade 22 by gas alone is very limited, and sometimes it is not possible to completely clean the attached materials on the blade 22. Further improvements are made on the basis of the above embodiments.

[0069] See also Figures 10 to 12 As shown, the cleaning plate 63 is sealingly and slidably connected to the connecting strip 61, one side of the cleaning plate 63 located in the cavity 62 is an inclined surface, and one side of the inclined surface is rotatably connected to a cover plate 64, a hinge rod 65 is provided on the cleaning plate 63, and the cover plate 64 is fixedly connected to the hinge rod 65, and the connecting strip 61 is respectively provided with sliding grooves 611 at both ends along the width direction of the cutter head 23, and both ends of the hinge rod 65 extend from the sliding grooves 611 and are fixedly connected to sealing plates 651, a sealing strip is provided on the sealing plate 651 and contacts with the surface of the connecting strip 61, and a pressure relief groove 612 is provided on the connecting strip 61.

[0070] See also Fig.12 As shown, an electromagnetic control assembly 7 is provided at one end of the connecting strip 61 along the width direction of the cutter head 23. When the electromagnetic control assembly 7 is turned on, the hinge rod 65 drives the cover plate 64 to rotate a certain angle and close the through slot 631.

[0071] See also Fig.11 As shown, one end of the cleaning plate 63 close to the blade 22 is a bevel, and the air outlet end of the second air hole 632 is located on the bevel.

[0072] See also Fig.12 and Fig.13As shown, the electromagnetic control assembly 7 includes an electromagnet 71 fixed to the side of the tool holder 21, a side of the connecting strip 61 close to the electromagnet 71 is fixedly connected to a limiting cylinder 72, a limiting block 73 matching the limiting cylinder 72 is slidably connected inside the limiting cylinder 72, the cross-section of the inner wall of the limiting cylinder 72 is a regular polygon, the limiting block 73 matches the limiting cylinder 72 and is slidably connected to the limiting cylinder 72, and an end of the limiting block 73 away from the limiting cylinder 72 is fixedly connected to an adsorption plate 74, and the adsorption plate 74 matches the electromagnet 71. An elastic member 75 is provided between the adsorption plate 74 and the tool holder 21, a telescopic member 76 is fixedly connected to one side of the adsorption plate 74, a connecting column 77 is fixedly connected to the end of the hinged rod 65 close to the electromagnet 71, an arc track 771 is provided on the circumferential side of the connecting column 77, a moving cylinder 78 is coaxially slid on the connecting column 77, a connecting block matching the arc track 771 is fixedly connected to the inner wall of the moving cylinder 78, and the telescopic member 76 is fixedly connected to the moving cylinder 78 on the side away from the adsorption plate 74.

[0073] The adsorption plate 74 is made of ferromagnetic material. When the electromagnet 71 is energized, the adsorption plate 74 approaches the electromagnet 71 under the action of magnetic force and is adsorbed by the electromagnet 71 .

[0074] During use, for large quantities of waste materials and waste materials that are easy to stick to the knife, after cleaning the blade 22 by gas blowing, the worker operates the control box to reduce the rotation speed of the rotating shaft 122 and energize multiple electromagnets 71. The adsorption plate 74 is strongly attracted by the electromagnet 71 and moves closer to the electromagnet 71. The movement of the adsorption plate 74 causes the moving cylinder 78 to move accordingly. At this time, under the action of the connecting block and the arc track 771, the hinged rod 65 drives the cover plate 64 to rotate a certain angle and makes the through groove 631 in a sealed state.

[0075] Since the gas in the cavity 62 cannot be released, the pressure in the cavity 62 increases rapidly, and the cleaning plate 63 moves toward the blade 22 under the action of the gas pressure. During the movement, the cleaning plate 63 cleans the blade 22, but it should be noted that the maximum moving distance of the cleaning plate 63 will not exceed the cutting edge of the blade 22.

[0076] When the cleaning plate 63 moves to a certain distance, the pressure relief groove 612 is connected with the cavity 62. At this time, the pressure in the cavity 62 decreases rapidly and a large amount of gas is released. The telescopic member 76 drives the cleaning plate 63 to reset. At this time, the pressure relief groove 612 is blocked, and the gas gathers again in the cavity 62 and continues to increase the pressure. Then, the above-mentioned action will be repeated to achieve multiple cleanings of the cleaning plate 63. After a period of time, the worker can operate the control box to restore the rotating shaft 122 to normal speed and cut off the power to the electromagnet 71. The adsorption plate 74 is reset under the action of the elastic member 75 and finally the cover plate 64 is flipped. At this time, the through groove 631 is in a connected state with the cavity 62 again, and the gas blows the blade surface of the blade 22 again.

[0077] Through the settings of the cover plate 64, the electromagnetic control component 7, the pressure relief groove 612 and the sealing plate 651, for large quantities of waste materials that are easy to stick to the blade, the worker operates the control box to reduce the speed of the rotating shaft 122 and make multiple electromagnetic control components 7 work. The hinged rod 65 drives the cover plate 64 to flip and make the through groove 631 in a sealed state, so that the cleaning plate 63 cleans the blade surface of the blade 22 under the action of air pressure, and cleans the waste materials that are difficult to remove accumulated on the blade 22, thereby further improving the cleaning effect of the blade 22, extending the continuous working time of the shredder, and improving the waste recovery efficiency.

[0078] Embodiment 5

[0079] Considering that after the cleaning plate 63 moves to a certain position, the pressure relief groove 612 will be connected with the cavity 62, and the pressure in the cavity 62 will be rapidly reduced and a large amount of gas will be released. In order to reuse this part of gas, further improvements are made on the basis of the above embodiment.

[0080] See also Fig.11 As shown, a guide plate 8 is fixedly connected to the connecting strip 61 . The guide plate 8 is located on one side of the pressure relief groove 612 and allows the gas to be ejected toward the blade 22 .

[0081] During use, when the cover plate 64 closes the through groove 631, the gas in the cavity 62 cannot be released and the pressure in the cavity 62 increases rapidly. At this time, the cleaning plate 63 moves toward the blade 22 under the action of air pressure. When the cleaning plate 63 moves to a certain distance, the pressure relief groove 612 is connected with the cavity 62, the pressure in the cavity 62 decreases rapidly and a large amount of gas is released. When the gas is ejected from the pressure relief groove 612, it is guided by the guide plate 8 and acts on the cleaning plate 63 again to clean the blade surface of the cleaning plate 63.
