Description

Technical Field

[0001] The utility model relates to the technical field of battery waste treatment, in particular to a battery core disassembly device. Background Art

[0002] The positive electrode, negative electrode, separator and other components contained in the battery core can be recycled by disassembling. These materials are of high value in battery production and can be used to manufacture new batteries or other products after recycling, realizing the recycling of resources.

[0003] However, a large amount of dust is generated during the disassembly of the battery core, which mainly comes from the different disassembly steps and links. The dust contains battery materials, such as metal particles and other chemicals, which can pollute the soil, water bodies and atmospheric environment. At the same time, the fine particles in the dust can enter the human body through breathing and cause damage to the respiratory system. Long-term exposure to such an environment may cause workers to develop respiratory diseases and may also cause damage to organs such as the nervous system and kidneys. In addition, the dust attached to the materials after disassembly may also cause the quality of the recycled products to decline or become unqualified, which invisibly increases the cost of the recycled products.

DETAILED DESCRIPTION

[0039] To make the technical problems solved, the technical solutions adopted, and the technical effects achieved by the present invention more clearly understood, the technical solutions of the embodiments of the present invention are described in further detail below. Obviously, the embodiments described are only a portion of the embodiments of the present invention, not all of them. All other embodiments derived by those skilled in the art based on the embodiments of the present invention without creative effort are also within the scope of protection of the present invention.

[0040] In the description of this utility model, unless otherwise expressly specified or limited, the terms "connected," "connected," and "fixed" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0041] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0042] The battery core, as the core component of the lithium-ion battery, is also called the battery cell. It is the internal structure of the battery formed by alternately stacking the positive and negative electrode materials together and winding them. It mainly consists of a positive electrode, a negative electrode, a separator and an electrolyte.

[0043] With the continuous development of the new energy industry, the production capacity of battery cores is also constantly improving. However, due to the influence of the battery core yield rate, waste core materials will still appear in the production process of battery cores. These materials can be recycled through disassembly, sorting and crushing. These materials have high value in battery production. After recycling, they can be used to manufacture new batteries or other products to realize the recycling of resources.

[0044] However, as can be seen from the background art, a large amount of dust is generated during the disassembly of the battery core, which mainly comes from the different disassembly steps and links. Among them, the dust contains battery materials, such as metal particles and other chemicals. If discharged directly without proper treatment, these dusts may pollute the soil, water bodies and atmospheric environment, especially heavy metal elements such as lead and cadmium, which can accumulate in the soil and water bodies, and have a long-term negative impact on the ecological environment. Secondly, the fine particles in the dust can enter the human body through the human respiratory tract and cause damage to the respiratory system. Long-term exposure to such an environment may cause workers to suffer from respiratory diseases and are more likely to cause further damage to the human nervous system, kidneys and other organs. Furthermore, the accumulation of dust may cause explosion risks, especially in closed or semi-closed working spaces. When the dust concentration reaches a certain level, it may cause an explosion due to static electricity or other ignition sources. At the same time, dust in the working space will also cause wear and blockage of production equipment, affecting the normal operation and service life of the equipment. In addition, the dust attached to the disassembled materials may also cause the quality of the recycled products to decline or become unqualified, which invisibly increases the cost of the recycled products.

[0045] In view of this, the present embodiment provides a battery core disassembly device, which mainly solves a series of technical problems mentioned in the above background technology by sucking and cleaning the dust attached to the cutting surface of the material by arranging a dust removal device on one side of the cutting surface where the electrode (including the positive electrode and the negative electrode) and the diaphragm are located.

[0046] Please refer to the attached Figure 2 The battery core disassembly equipment includes:

[0047] The material unwinding roller 10 is configured to support the material to be disassembled (battery core) during the disassembly of the battery core, and can release the material to be disassembled while supporting the material to be disassembled. The battery core to be disassembled can be released from the original winding state under the action of the material unwinding roller 10 or other mechanisms (such as the material winding roller 20 described later) for subsequent disassembly work.

[0048] It can be understood that the material unwinding roller 10 is usually made of stainless steel or other suitable materials, and has certain mechanical strength and corrosion resistance, so that the material unwinding roller 10 can ensure that the material to be disassembled remains flat and stable during the unwinding process, avoids twisting or breakage, and improves the recycling rate of the material.

[0049] During the material disassembly process, the material unwinding roller 10 can release the material to be disassembled by rotating, and may be equipped with a tension control system to ensure the stability and consistency of the unwinding process.

[0050] Of course, in some embodiments, in addition to the above-mentioned active roller form, the material unwinding roller 10 can also be in the form of a passive roller, for example, passively unwinding under the action of the subsequent material winding roller 20 to ensure that the core material is in a good tension state in the device, ensuring that the battery core can be disassembled smoothly.

[0051] The material winding roller 20, in actual application, is configured to collect the disassembled material for subsequent recycling or processing. Therefore, in order to reserve corresponding installation space for the subsequent separation scraper 30 and the conveying path for the material to be disassembled and the disassembled material, the material winding roller 20 and the material unwinding roller 10 are arranged at intervals from each other in the battery core disassembly equipment.

[0052] Similar to the material unwinding roller 10 , the material winding roller 20 is also made of a suitable material and needs to have sufficient strength and durability to ensure stability during the material winding process.

[0053] Likewise, during the material disassembly process, the material reel 20 can also collect the disassembled material by rotating.

[0054] It should be noted that in the battery core disassembly equipment, the rotation of the material unwinding roller 10 and the material rewinding roller 20 is determined by the specific design of the equipment and the requirements of the disassembly process. In one embodiment, the material rewinding roller 20 can be configured to rotate actively, while the material unwinding roller 10 can be configured to rotate actively or passively. In other embodiments, the unwinding and rewinding of the unwinding and rewinding of the material to be disassembled on the material unwinding roller 10 and the material rewinding roller 20, respectively, can be achieved by an external power source.

[0055] For example, in this embodiment, an unwinding drive wheel and a winding drive wheel whose central axes are parallel to the corresponding roller bodies are provided on the material unwinding roller 10 and the material winding roller 20, and the drive wheels are respectively pressed against the material to be disassembled and the disassembled material and rotated so that the drive wheels can drive the material to be unwound and wound on the corresponding roller bodies when rotating;

[0056] For example, a material clamp can be provided between the material unwinding roller 10 and the material winding roller 20 to clamp the material to be disassembled and pull the disassembled material from the first position to the second position to realize passive unwinding and winding of the material on the corresponding roller body.

[0057] Generally speaking, the central axes of the material winding roller 20 and the material unwinding roller 10 are set to be parallel to each other, so as to ensure that the unwinding and winding processes of the material to be disassembled and the disassembled material remain stable to a certain extent.

[0058] From the above content, we can know that the battery core includes a positive electrode, a negative electrode and a separator. Figure 1 It can be seen that the main structure of the material to be disassembled is the upper diaphragm 100, the positive electrode sheet 200, the lower diaphragm 300 and the negative electrode sheet 400 stacked in sequence. In order to ensure that the upper diaphragm 100, the positive electrode sheet 200, the lower diaphragm 300 and the negative electrode sheet 400 can all be collected by the material winding roller 20, in this embodiment, the material winding roller 20 includes a first diaphragm winding roller, a second diaphragm winding roller, a positive electrode winding roller and a negative electrode winding roller. The winding rollers are spaced apart from each other to avoid interference between the diaphragm and the electrode sheet during the winding process. Among them, the first diaphragm winding roller is used to collect the upper diaphragm 100. It is set close to the positive electrode winding roller so that the adjacent stacked upper diaphragm 100 and the positive electrode sheet 200 can be collected smoothly. Correspondingly, the second diaphragm winding roller is set close to the negative electrode winding roller so that the adjacent stacked lower diaphragm 300 and the negative electrode sheet 400 can be collected smoothly.

[0059] The separation scraper 30 is used to separate the electrode and the diaphragm through the blade head. The separation scraper 30 is specifically arranged between the material unwinding roller 10 and the material winding roller 20, and the blade head of the separation scraper 30 is arranged toward one end close to the material unwinding roller 10 to ensure that the blade head of the separation scraper 30 can be directed toward the material to be disassembled released by the material unwinding roller 10.

[0060] Specifically, the main function of the separation scraper 30 is to effectively separate the positive and negative electrodes from the diaphragm without damaging the battery core. In actual application scenarios, the material disassembly path between the material unwinding roller 10 and the material winding roller 20 needs to be planned in advance so that the separation scraper 30 can be set on the disassembly path of the corresponding material. This structural design can ensure that the separation scraper 30 is in close contact with the surface of the corresponding material to ensure the separation effect.

[0061] It should be noted that the number and distribution of scrapers may vary depending on the design requirements of the battery core disassembly equipment and the size of the battery core. For example, in the embodiment described above where the battery core is mainly composed of an upper separator 100, a lower separator 300, a positive electrode sheet 200, and a negative electrode sheet 400, at least two separation scrapers 30 should be provided, and the two separation scrapers 30 are used to separate the upper separator 100 from the positive electrode sheet 200, and the lower separator 300 from the negative electrode sheet 400, respectively. Of course, in other embodiments, three separation scrapers 30 can also be provided, based on the above, to separate the positive electrode sheet 200 from the lower separator 300, so that the upper separator 100 from the positive electrode sheet 200, and the lower separator 300 from the negative electrode sheet 400 can be separated smoothly by the other two separation scrapers 30.

[0062] The dust removal device 40 is arranged at the end of the separation scraper 30 away from its blade head. A hollow vacuum chamber 41 is formed inside the dust removal device 40. The vacuum chamber 41 is connected to an external negative pressure source. Dust extraction ports 42, both connected to the vacuum chamber 41, are respectively provided on opposite sides of the end of the vacuum chamber 41 close to the separation scraper 30. The two dust extraction ports 42 are used to face the cutting surface of the electrode and the cutting surface of the diaphragm, respectively.

[0063] The dust removal device 40 adopts the above-mentioned configuration, and its main technical effects are reflected in the following aspects:

[0064] 1. The dust extraction device can effectively collect the dust generated during the cutting process and prevent it from being directly discharged into the air, thereby reducing pollution to the environment.

[0065] 2. Reduce the dust concentration in the working environment during the separation process, and even avoid the presence of battery core material dust in the working environment, thereby reducing or even avoiding the risk of possible explosion and eliminating operational safety hazards.

[0066] 3. Reduce the chance of workers being exposed to dust, which is beneficial to their health.

[0067] 4. Make the disassembled materials meet the requirements of reuse, thereby improving the quality of products produced by material reuse.

[0068] 5. Avoid dust accumulation in battery core disassembly equipment, solve the problem of equipment wear and blockage caused by dust accumulation, and extend the service life of the equipment.

[0069] 6. Reduce the cost of cleaning the working environment.

[0070] It should be noted that in actual applications, the dust removal device 40 is mainly used to collect and process dust and fine particles generated during the disassembly process. Therefore, the dust removal device 40 is set at the end (rear end) of the separation scraper 30 away from its blade head, so that the dust removal device 40 can be as close as possible to the material just separated, ensuring that the dust generated can be collected immediately after the separation scraper 30 completes the separation of the positive and negative electrodes from the diaphragm.

[0071] In this embodiment, the cutting surfaces of the electrode sheet and the diaphragm are defined as a side of the electrode sheet for stacking with the diaphragm, and a side of the diaphragm for stacking with the electrode sheet. For example, the cutting surface of the positive electrode sheet 200 is a side of the positive electrode sheet 200 for stacking with the upper diaphragm 100, and correspondingly, the cutting surface of the upper diaphragm 100 is a side thereof for stacking with the positive electrode sheet 200. The cutting surface of the negative electrode sheet 400 is a side of the negative electrode sheet 400 for stacking with the lower diaphragm 300, and correspondingly, the cutting surface of the lower diaphragm 300 is a side thereof for stacking with the negative electrode sheet 400.

[0072] In this embodiment, the positive electrode sheet 200 and the lower diaphragm 300 can be pre-separated by manual or mechanical operation, and then the upper diaphragm 100 and the positive electrode sheet 200 are separated by one of the isolation scrapers, and the lower diaphragm 300 and the negative electrode sheet 400 are separated by another isolation scraper. In addition to being set between the upper diaphragm 100 and the positive electrode sheet 200, and between the lower diaphragm 300 and the negative electrode sheet 400, in the embodiment of the above three separation scrapers 30, the dust removal device 40 can also be set at the separation scraper 30 located between the positive electrode sheet 200 and the lower diaphragm 300.

[0073] Please continue to refer to the attached Figure 2 A first guide surface 43 and a second guide surface 44 are formed on opposite sides of one end of the dust removal device 40 near the separation scraper 30. Two dust extraction ports 42 are respectively provided on the first guide surface 43 and the second guide surface 44. In actual application, the first guide surface 43 and the second guide surface 44 can provide corresponding auxiliary guidance for the movement path of the electrode piece and the diaphragm, so that the electrode piece and the diaphragm can be supported within a certain range after cutting and separation, thereby reducing the vibration of the electrode piece and the diaphragm.

[0074] Specifically, the first guide surface 43 and the second guide surface 44 extend from close to the separation scraper 30 to away from the separation scraper 30 and the distance between the two gradually increases, so that in the process of the separation scraper 30 separating the material to be disassembled, on the basis of providing a certain guiding function for the electrode and the diaphragm, the first guide surface 43 and the second guide surface 44 can be respectively located close to the cutting surface of the electrode and the cutting surface of the diaphragm.

[0075] It can be understood that the closer the first guide surface 43 and the second guide surface 44 are to the cutting surface of the electrode piece and the diaphragm, the closer the dust extraction port 42 is to the cutting surface of the electrode piece and the diaphragm. The main purpose of such arrangement is:

[0076] The closer the dust extraction port 42 is to the dust source (cutting surface), the better the negative pressure effect of the vacuum chamber 41 and the better the dust collection effect. The reason is that the smaller the gap between the guide surface (the first guide surface 43 or the second guide surface 44) and the cutting surface, the greater the air flow resistance in the gap, making it easier for dust-laden air to be sucked into the vacuum chamber 41.

[0077] The smaller the gap between the guide surface and the cutting surface, the less likely dust is to spread in the air flow. The dust on the cutting surface can be quickly captured and will not spread outside the dust removal device 40 from the gap between the guide surface and the cutting surface.

[0078] It is understandable that in order to avoid the dust extraction device from scratching the electrode or diaphragm and affecting the recovery of the battery core, the first guide surface 43 and the second guide surface 44 maintain a certain safety gap between themselves and the electrode surface and the diaphragm surface respectively during the disassembly of the battery core.

[0079] In one embodiment, if Figure 2 As shown, a dust sweeper 421 is provided on one side of the dust extraction port 42 close to the separation scraper 30. The dust sweeper 421 is mainly used to assist the dust removal device 40 in collecting dust and fine particles more effectively during the disassembly of the battery core. When the pole piece and the diaphragm are running along the disassembly path, the dust sweeper 421 will clean the corresponding cutting surface so that the dust attached to the cutting surface can fall off more easily and be collected more effectively by the dust removal device 40.

[0080] The dust sweeper 421 is usually located near the dust extraction port 42 or along the front and / or rear side of the material disassembly path to ensure that after the scraper completes the separation of the positive and negative electrodes from the diaphragm, the dust swept down or blocked by the dust sweeper 421 can be quickly collected.

[0081] In this example, the dust sweeper 421 is arranged at the edge of the dust extraction port 42 in a direction perpendicular to the disassembly path of the electrode or diaphragm to ensure that the cutting surface can be covered by the dust sweeper 421 in the width direction, thereby improving the dust cleaning effect.

[0082] Please continue to refer to the attached Figure 2-Figure 3 In order to facilitate more effective and convenient storage of disassembled materials, the battery core disassembly equipment also includes a storage box 50. A hollow storage cavity 51 is formed inside the storage box 50 to provide storage space for the disassembled materials, so that the disassembled materials can be uniformly transported through the storage box 50 to facilitate subsequent processes.

[0083] In actual application, the storage box 50 is set at a position of the equipment close to the supporting surface (such as the ground in the working scene) to facilitate the rapid transportation of the disassembled materials after unified collection. For this reason, the height of the material unwinding roller 10 will be greater than the storage box 50, so a feed gap 52 connecting to the storage cavity 51 is opened on the top of the storage box 50. The width of the feed gap 52 needs to be adaptively adjusted according to the size of the disassembled material so that the disassembled material can be smoothly collected into the storage cavity 51 through the feed gap 52.

[0084] Furthermore, a roller opening 53 communicating with the storage chamber 51 is provided on one side of the storage box 50. The wall of the storage chamber 51 is also provided with an abutment portion 54 surrounding the roller opening 53. The material take-up roller 20 is movable relative to the storage chamber 51. The material take-up roller 20 can move into the storage chamber 51 through the roller opening 53, and can also move out of the storage chamber 51 through the roller opening 53 and out of the storage chamber 51. It can be understood from the above that the roller opening 53 is used to provide space for the take-up roller to enter and exit the storage box 50. The fact that the take-up roller can enter and exit the storage chamber 51 can further improve the collection efficiency of the disassembled material. During the collection process of the disassembled material, the material take-up roller 20 is inside the storage chamber 51, so that the disassembled material that enters the storage chamber 51 through the feed slit 52 can be uniformly taken up and collected by the corresponding material take-up roller 20. When the disassembled material is completely disassembled, or the disassembled material on the material winding roller 20 is in a full state (when the size or weight of the disassembled material on the material winding roller 20 is greater than the full threshold of the winding roller), the material winding roller 20 can slowly move from the storage chamber 51 to the outside of the storage chamber 51 through the roller mouth 53. During this process, one end of the material wound on the material winding roller 20 can abut against the above-mentioned abutment 54 to prevent the disassembled material from escaping from the storage box 50, and as the material winding roller 20 continues to move, the disassembled material can detach from the material winding roller 20 and fall into the storage box. During this period, no operator intervention is required, which is safe and efficient, and is conducive to improving the material recycling efficiency.

[0085] On the basis of the above-mentioned embodiment which also includes a storage box 50, the storage box 50 is provided with two rotatable dust removal rollers 55 in the storage cavity 51, and the two dust removal rollers 55 are respectively arranged near the opposite sides of the feed gap 52. After the disassembly, the material enters the storage cavity 51 through the feed gap 52 and is wound onto the material winding roller 20. The opposite side surfaces of the disassembled material will be respectively brushed by the two dust removal rollers 55, which has the effect of further sweeping off the dust on the surface of the material. By setting the dust removal rollers 55 in the storage box, the dust can be prevented from spreading outside the storage box 50 as much as possible, thereby improving the dust collection efficiency.

[0086] It should be understood that the two dust removal rollers 55 should use bristles made of relatively soft material to avoid damaging the surface of the material. At the same time, the bristles on the two dust removal rollers can be set to at least interfere with each other. On the basis of ensuring that the disassembled material can pass normally between the two dust removal rollers 55, the interference between the dust removal rollers 55 and the disassembled material is increased to improve the dust removal effect.

[0087] In addition, the storage chamber 51 is also connected to an external negative pressure source so that the dust swept down by the dust removal roller 55 can be located in the storage chamber 51 and collected by the external negative pressure source, thereby avoiding the accumulation of dust in the storage chamber 51 and causing secondary contamination of the disassembled materials.

[0088] Continuing on the basis of the above technical solution, Figure 2 As shown, a first transmission wheel 551 is provided at one end of each of the two dust removal rollers 55, and a second transmission wheel 552 is provided between the two transmission wheels. Both first transmission wheels 551 are in driving engagement with the second transmission wheel 552. A driving device 553 (such as a motor, or a device consisting of a motor and a reduction mechanism) is also provided on the storage box 50. The driving device 553 is fixedly mounted to the storage box 50 via its fixed end, and is drivingly connected to the second transmission wheel 552 via its driving end.

[0089] The first transmission wheel 551 and the second transmission wheel 552 can be coordinated through transmission components such as gears, belts, and chains. The main purpose is to ensure that the two second transmission wheels 552 can respectively drive the two dust removal rollers 55 to rotate synchronously and in opposite directions. The rotation direction of the two dust removal rollers 55 is set to the opposite direction of the disassembly path of the disassembled material to improve the dust removal efficiency of the dust removal rollers 55.

[0090] In one embodiment, if Figure 2 As shown, the storage box 50 is located in the storage cavity 51 and is also provided with a cutting component 60. The cutting component 60 is arranged on the cavity wall of the storage cavity 51 away from the roller mouth 53. The cutting component 60 is mainly used to cut the disassembled material to avoid the material wound on the material winding roller 20 being too large and causing the material winding roller 20 to be unable to continue winding.

[0091] Specifically, the cutting assembly 60 includes a cutter 61 and a driving mechanism 62. The fixed end of the driving mechanism 62 is installed on the cavity wall of the storage cavity 51, and the cutter 61 is installed on the driving end of the driving mechanism 62. The driving end of the driving mechanism 62 can drive the cutter 61 to reciprocate in a direction parallel to the extension direction of the feed gap 52.

[0092] When the winding amount of the material winding roller 20 reaches its maximum value and the material to be disassembled on the material unwinding roller 10 has not been completely unwound, the driving mechanism 62 can drive the cutter 61 to move along the width direction of the disassembled material to cut off the disassembled material, so that the material winding roller 20 can separate the disassembled material wound thereon into the storage chamber 51, thereby facilitating the continued winding of the disassembled material.

[0093] Furthermore, the storage box 50 is located in the storage cavity 51 and is further provided with a guide roller group 70. The guide roller group 70 is arranged between the cutting component 60 and the material winding roller 20. The guide roller group 70 includes a first guide roller 71 and a second guide roller 72, wherein the second guide roller 72 and the first guide roller 71 are respectively arranged on opposite sides of the feed gap 52 and are located outside the storage box 50. The first guide roller 71 and the second guide roller 72 can clamp the disassembled material and rotate in opposite directions under the drive of an external power source to introduce the disassembled material into the feed gap 52, thereby preventing the material between the material winding roller 20 and the material unwinding roller 10 from breaking, causing the material to retract into the material unwinding roller 10, and requiring manual guidance of the material to the material winding roller 20 again.

[0094] On the basis of the above, if Figure 2 As shown, a splicing mechanism 80 is disposed between the material reel 20 and the cutting assembly. This splicing mechanism 80 is configured to connect the ends of the two pole pieces or two diaphragms. The splicing mechanism 80 primarily comprises a third guide roller 81 and a fourth guide roller 82. The fourth guide roller 82 and the third guide roller 81 are positioned on opposite sides of the disassembled material collection path and within the storage chamber 51. The third and fourth guide rollers 81, 82 clamp the disassembled material and, driven by an external power source, rotate in opposite directions, pulling the disassembled material wound on the material reel 20 a predetermined distance.

[0095] A splicing device 83 for splicing materials is also provided between the third guide roller 81, the fourth guide roller 82 and the guide roller group 70. When the material is broken, the guide roller group 70 can rely on the first guide roller 71 and the second guide roller 72 to clamp one end of the broken material, and the splicing mechanism can rely on the third guide roller 81 and the fourth guide roller 82 to clamp the other end of the broken material. Subsequently, the first guide roller 71, the second guide roller 72, the third guide roller 81 and the fourth guide roller 82 rotate to guide the opposite ends of the broken material towards each other to the splicing device 83, so that the splicing device 83 can re-splice the two ends of the broken material to facilitate the continued recovery of the material after disassembly.

[0096] In one embodiment, the cutting assembly 60 and the splicing device 83 are both located between the guide roller group 70 and the third guide roller 81 and the fourth guide roller 82, and the cutting assembly 60 and the splicing device 83 are arranged relative to each other, and the disassembly path of the disassembled material is located between the cutting assembly 60 and the splicing device 83 to avoid mutual interference between the two.

[0097] According to any of the above embodiments, a tensioning shaft 90 is further provided between the separation scraper 30 and the material winding roller 20, and the tensioning shaft 90 can reciprocate between a position close to the line between the separation scraper 30 and the material winding roller 20 and a position away from the line between the separation scraper 30 and the material winding roller 20.

[0098] During the disassembly of the battery core, it is crucial to maintain good tension control. The main purpose of setting a movable and adjustable tensioning shaft 90 between the material unwinding roller 10 is to adjust the tension degree of the material to be disassembled and the disassembled material to ensure the smooth progress of the disassembly process.
