Description

Technical Field

[0001] The present invention relates to the technical field of dust removal equipment, and specifically relates to a waste rubber strip collection device that can prevent pollution. Background Art

[0002] During the production and processing of lithium battery electrodes, in order to facilitate processing, rubber strips need to be adhered to the electrodes. In subsequent processing, the rubber strips need to be peeled off to avoid affecting the performance of the electrodes. The peeled rubber strips need to be collected and then centrally processed. In the traditional process of collecting rubber strips, generally, after the rubber strips are peeled off by the previous peeling device, they are directly transported into the rubber strip collection box. This will cause the following problems:

[0003] 1. During the process of peeling the rubber strips, certain dust-laden gases will be generated. If these dusts enter the dust-free workshop, they may not only pollute the environment but also affect the performance of the electrodes.

[0004] 2. The traditional method of collecting rubber strips is to directly transport the rubber strips into the rubber strip collection box. This method has the problem that the suction device above the rubber strip collection box cannot work effectively, resulting in the inability to use a plastic bag to collect the rubber strips. Furthermore, the rubber strips may directly fall into the collection box due to blockage of the plastic bag at the material outlet.

[0005] 3. After collecting a certain amount of rubber strips, it is necessary to manually pour the rubber strips from the collection box into the plastic bag. This process may also generate a large amount of dust, further polluting the dust-free workshop.

[0006] Therefore, an improved technical solution is needed to effectively collect the rubber strips and avoid the occurrence of the above problems. Summary of the Invention

[0040] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0041] like Figures 1 to 3 As shown, a pollution-proof waste rubber strip collection device comprises a chassis 1, a gas-solid separation bin 2 is provided in the upper part of the chassis 1, a detachable material collection box 3 is provided in the lower part of the chassis 1, the lower end of the gas-solid separation bin 2 is connected to the upper end of the material collection box 3 via a sealing transition structure 4, a negative pressure structure 5 is provided on the side of the material collection box 3, the negative pressure structure 5 is connected to the gas-solid separation bin 2 and the material collection box 3, and is used to extract the gas in the gas-solid separation bin 2 and the gas at the bottom of the material collection box 3, so that the material bag can be attached to the inner wall of the material collection box 3.

[0042] It should be noted that: in this embodiment, the gas-solid separation bin 2 is fixedly arranged at the upper part of the chassis 1, and the material receiving box 3 is arranged at the lower part of the chassis 1. The bottom of the material receiving box 3 is provided with universal wheels and can freely enter and exit from the lower part of the chassis 1. During the use process, the discharge port of the waste rubber strip device capable of preventing pollution of the present invention is docked with the rubber strip peeling device of the previous process through the discharge pipeline 9. The peeled rubber strip and the dust-containing gas will directly enter the gas-solid separation bin 2 through the discharge pipeline 9. The upper part of the negative pressure structure 5 is connected and arranged with the gas-solid separation bin 2, and the lower part is connected and arranged with the air guide channel 302 of the material receiving box 3. In this way, it is possible to use one suction device to complete the suction parts required at the upper and lower positions. On the one hand, the cost of purchasing multiple suction devices can be saved. On the other hand, the gas extraction structure of the upper gas-solid separation bin 2 and the gas extraction structure of the lower material receiving box 3 are arranged in an up-and-down docking manner and are both arranged inside the chassis 1, saving the structural occupied space and making the overall volume of the equipment smaller. In addition, the material receiving box 3 is provided with an air guide channel 302 to dock with the extraction device, which is mainly used to extract the gas between the outer side of the material bag and the inner wall of the material receiving box 3 in the material receiving box 3, so that the material bag can be tightly attached to the inner wall of the material receiving box 3. In traditional operations, due to the suction effect of the upper gas-solid separation bin 2 and the lack of suction effect in the lower material receiving box 3, if the material bag is sleeved in the material receiving box 3, there is air between the outer wall of the material bag and the inner wall of the material receiving box 3, and the material bag will not be attached to the inner wall of the material receiving box 3. When the gas is extracted from the upper part, the material bag will enter the lower part of the gas-solid separation bin 2, thereby blocking the material dropping port 103 at the lower end of the gas-solid separation bin 2, and further causing the colloid to be blocked, affecting the operation of the equipment. Therefore, to solve this problem, the equipment in traditional operations generally does not place a material bag in the material receiving box 3, but directly lets the rubber strip fall into the material receiving box 3. When the material receiving box 3 reaches a certain amount, the material receiving box 3 is removed, the rubber strip is poured out and transferred into the material bag. However, during the process of pouring out the rubber strip, a certain amount of dust will also be generated due to the flipping, moving and friction of the rubber strip. Moreover, when the rubber strip is poured out and transferred into the material bag, it is usually completed in a dust-free workshop. In this way, the dust generated during the transfer of the rubber strip will overflow into the dust-free workshop and cause pollution to the workshop. By using the waste rubber strip device capable of preventing pollution of the present invention, the rubber strip can be directly dropped into the material bag. After collecting a certain amount, the material receiving box 3 is removed, and the bag mouth of the material bag can be directly sealed, without the need to pour out and transfer it into the bag, avoiding the generation of dust during the transfer of the rubber strip and causing pollution to the workshop.

[0043] Such as Figure 1 and Figure 9As shown, the chassis 1 is hollow inside, and a middle partition 101 is provided in the middle thereof. A separation bin mounting frame 102 is provided in the middle of the middle partition 101. A blanking port 103 is formed corresponding to the penetration of the middle partition 101 in the middle of the separation bin mounting frame 102. Baffle mounting positions 104 are provided on both sides of the blanking port 103, and a baffle extension port 105 is provided on the side of the baffle mounting position 104 close to the blanking port 103. The upper top of the chassis 1 is open, and the lower part is open on one side. A control mounting groove 106 is also provided on the outer side of the chassis 1.

[0044] It should be noted that: in this embodiment, the main body of the chassis 1 is made of sheet metal material, and its upper end is open. The middle partition 101 divides the chassis 1 into a separation bin mounting position in the upper part and a material box mounting position in the lower part. The gas-solid separation bin 2 is installed in the separation bin mounting position, and the material receiving box 3 is arranged in the material box mounting position in the lower part. The upper end of the gas-solid separation bin 2 is fixedly connected to the chassis 1, and its lower end is fixed on the separation bin mounting frame 102 of the middle partition 101. The inside of the gas-solid separation bin 2 is hollow, and its lower end is open. The gas-solid separation bin 2 is arranged directly above the blanking port 103, so that the blanking port 103 is communicated with the inside of the gas-solid separation bin 2. The baffle structure 6 is arranged on the baffle mounting positions 104 on both sides of the blanking port 103. The sealing transfer structure 4 is installed on the bottom surface of the middle partition 101 and is fixedly connected to the bottom surface of the middle partition 101. The lower end of the sealing transfer structure 4 is butted against the material receiving box 3, so that the rubber material can directly fall into the material receiving box 3 from the blanking port 103. A plurality of maintenance windows are provided on the outer side of the chassis 1 corresponding to the structures to be maintained. The side door at the lower part of the chassis 1 is convenient for the entry and exit of the material receiving box 3. The control structure 8 is installed in the control mounting groove 106.

[0045] As Figure 4 、 Figure 5 and Figure 8 shown, a partition plate 201 is provided in the upper inner part of the gas-solid separation bin 2. The partition plate 201 divides the gas-solid separation bin 2 into an upper gas separation bin 202 and a lower solid separation bin 203. The partition plate 201 is a perforated plate. An isolation plate 204 is provided on the inner side wall of the gas separation bin 202. A number of air holes are evenly provided on the isolation plate 204. An air separation channel 205 is formed between the isolation plate 204 and the inner side wall of the gas separation bin 202. The negative pressure structure 5 is communicated with the air separation channel 205 on one side of the gas separation bin 202. A number of air outlet grids are also provided on the isolation plate 204 far from the negative pressure structure 5. A blanking port is provided on the side of the solid separation bin 203, and the blanking port is connected and docked with a blanking pipeline 9. The upper end of the blanking pipeline 9 is docked with the discharge port of the previous process.

[0046] It should be noted that: in this embodiment, the gas-solid separation bin 2 is in the shape of a square funnel, and the partition plate 201 is a mesh plate, which can allow the dust-carrying gas to pass through the partition plate 201 on the one hand, and prevent the rubber strip from moving upward under the action of the suction force on the other hand; the gas separation bin 202 is square in shape, and a negative pressure mounting port is provided on the side on which the negative pressure structure 5 is installed, and the negative pressure mounting port is connected to the gas separation channel 205; a plurality of air outlet grids are provided on the isolation plate 204 of the gas separation bin 202 away from the negative pressure structure 5, in order to ensure that the suction force on the four sides of the gas separation bin 202 is uniform; the discharge pipe The outer port of the channel 9 is connected to the discharge port of the previous process. After the rubber strip is peeled off from the electrode in the previous process, it enters the discharge pipe 9. Since the solid separation chamber 203 and the gas separation chamber 202 are separated by a mesh plate, when the negative pressure structure 5 sucks the gas from the gas separation chamber 202, it will also suck the gas in the discharge pipe 9 at the same time. On the one hand, the gas with dust in the discharge pipe 9 can be extracted and discharged to avoid contaminating the electrode peeled off in the previous process. On the other hand, the suction force of the negative pressure structure 5 can increase the moving speed of the rubber strip in the discharge pipe 9 and increase the direction of the rubber strip to the gas-solid separation chamber 2. The moving potential energy of the rubber strip is that the outer surface of the rubber strip has a certain viscosity. In the traditional operation, the rubber strip often adheres to the inner wall of the material discharge pipe 9, which leads to the blockage of the material discharge pipe 9. If the material discharge pipe 9 is blocked, it can only be stopped and disassembled for maintenance. The anti-pollution waste rubber strip collection equipment of the present invention is used to collect the rubber strip. The setting of the negative pressure structure 5 can quickly suck out the peeled rubber strip while extracting the dust-carrying gas from the material discharge pipe 9. The extraction force generated by the negative pressure structure 5 is greater than the friction between the rubber strip surface and the material discharge pipe 9, so that the rubber can be smoothly The rubber strip is pulled out of the feeding pipe 9, and the speed at which the extraction force generated by the negative pressure structure 5 moves the rubber strip is greater than the peeling speed of the rubber strip. That is to say, after the rubber strip in the feeding pipe 9 is extracted and falls into the receiving box 3, the next rubber strip will be peeled out and transferred to the feeding channel. This can completely avoid the problem of mixing and adhering to each other in the feeding pipe 9 and causing blockage of the feeding pipe 9. When the rubber strip falls from the feeding port into the solid separation bin 203, the upward extraction force generated by the negative pressure structure 5 is smaller than the gravity of the colloid itself, so that the rubber strip will not be adsorbed and moved upward when it comes out of the feeding port, but will effectively ensure that it falls downward.

[0047] like Figure 4 , Figure 5 and Figure 8 As shown, an air storage bag 206 is provided on the top of the air separation chamber 202 , and the air storage bag 206 is connected to a blowing pipe 207 through a control valve, and the blowing pipe 207 passes through the partition plate 201 and is connected to the solid separation chamber 203 .

[0048] It should be noted that: in this embodiment, a top cover is provided at the top of the air separation chamber 202. A gas storage installation groove is recessed in the middle of the top cover. The gas storage bag 206 is fixed in the gas storage installation groove of the top cover, and its air outlet is connected to the blowing pipe 207 through a control valve. The lower end of the blowing pipe 207 passes through the partition plate 201 of the gas-solid separation chamber 2 and extends into the solid separation chamber 203. The gas storage bag 206 is provided for, on the one hand, blowing off the rubber strips accidentally adhered to the inner wall of the solid separation chamber 203 and dropping them into the material collection box 3, and on the other hand, cleaning the dust inside the gas-solid separation chamber 2 to avoid dust accumulation in the gas-solid separation chamber 2. An inductor is provided inside the gas-solid separation chamber 2, which can sense the rubber strips adhered to the inner wall of the gas-solid separation chamber 2. Both the inductor and the control valve are electrically connected to the control main board, and the operation is controlled by the control main board.

[0049] As Figure 1 , Figure 6 and Figure 7 shown, the sealing adapter structure 4 includes a movable gland 401 and a bellows seal 402. The movable gland 401 covers the upper port of the material collection box 3. The bottom of the bellows seal 402 is fixed to the top surface of the movable gland 401, and the top of the bellows seal 402 is fixedly connected to the chassis 1. A material collection cylinder 403 is further provided above the movable gland 401. The material collection cylinder 403 is fixedly connected to the chassis 1, and its output end is fixedly connected to the upper end surface of the movable gland 401.

[0050] It should be noted that: in this embodiment, the movable gland 401 covers the upper port of the material receiving box 3. The upper end of the bellows seal cover 402 is fixed to the bottom surface of the middle partition plate 101 inside the chassis 1, and the lower end is fixed to the upper end surface of the movable gland 401. Four material receiving cylinders 403 are provided and are all fixed to the middle partition plate 101 of the chassis 1. The output ends of the four material receiving cylinders 403 are respectively connected to the four corners of the movable gland 401. The four material receiving cylinders 403 are all in telecommunication connection with the main control board and cooperate under the control of the main control board to realize the up and down movement of the movable gland 401. The setting of the four material receiving cylinders 403 can, on the one hand, make the movable gland 401 tightly cover the upper end surface of the material receiving box 3, increasing the sealing performance between the movable gland 401 and the material receiving box 3 and preventing the dust-containing gas generated in the material receiving box 3 from overflowing and polluting the dust-free workshop; on the other hand, it can use the pressure of the movable gland 401 on the material receiving box 3 to press the opening of the plastic bag in the material receiving box 3 between the material receiving box 3 and the movable gland 401, preventing the port of the plastic bag from falling into the material receiving box 3, which may lead to the rubber strip not accurately falling into the plastic bag. If the rubber strip falls outside the plastic bag, it is necessary to manually transfer the rubber strip into the plastic bag. On the one hand, this will increase the workload of the workers and reduce the work efficiency. On the other hand, when the workers pick up and throw the rubber strip into the plastic bag, dust will also be generated. At this time, the equipment is in a stopped state and the movable gland 401 is also in an open state, so the dust generated by manual transfer of the rubber strip will directly float in the air of the dust-free workshop, thus causing pollution to the dust-free workshop; while if the movable gland 401 is used to press the plastic bag, the rubber strip can accurately fall into the plastic bag, and there is no need for manual transfer of the rubber strip into the plastic bag again. After taking it out, the bag mouth can be directly sealed, which can greatly reduce the probability of dust floating into the dust-free workshop.

[0051] As Figure 2 , Figure 6 and Figure 7 shown, a baffle structure 6 is further provided between the seal transfer structure 4 and the gas-solid separation bin 2. The baffle structure 6 includes a movable baffle 601 and a baffle pushing cylinder 602. The baffle pushing cylinder 602 is fixed inside the chassis 1, and its output end is fixedly connected to the movable baffle 601 and can drive the movable baffle 601 to move to the bottom of the gas-solid separation bin 2.

[0052] It should be noted that: in this embodiment, there are two groups of the baffle structures 6, which are symmetrically installed on the baffle installation positions 104 on both sides of the blanking port 103. The movable baffle 601 is arranged on the baffle pushing cylinder 602 and is fixedly connected to the output end of the baffle pushing cylinder 602, and can move back and forth by the baffle pushing cylinder 602. The baffle pushing cylinder 602 is fixed on the middle partition 101, and its output end faces the direction of the blanking port 103. On the side of the baffle installation position 104 facing the blanking port 103, there is also a baffle extension port 105, and below the baffle extension port 105, there is also a cylinder output end extension port communicated with it. In this way, when the baffle pushing cylinder 602 drives the movable baffle 601 to move forward, the output end of the cylinder and the movable plate can just extend out from the baffle extension port 105 and the cylinder output end extension port. When extending out on both sides at the same time, the blanking port 103 can be just closed, so that the rubber strip cannot fall from the blanking port 103, realizing the function of closing the blanking port 103 to block the rubber strip. This baffle structure 6 is generally used when the rubber strips in the material receiving box 3 are centrally collected to a certain amount and need to be removed and transferred. The blanking port 103 needs to be closed to prevent the rubber strips from falling to the ground. The baffle pushing cylinder 602 is in telecommunication connection with the main control board, and the operation is controlled by the main control board.

[0053] As Figures 2 to 7 shown, the top of the material receiving box 3 is open, and a gas guide hole plate 301 is arranged on the inner bottom plate thereof. A gas guide channel 302 is formed between the gas guide hole plate 301 and the bottom plate. Air holes are arranged at the lower part of the inner side wall of the material receiving box 3. An air duct sealing plate 303 is arranged on the outer side wall of the material receiving box 3 corresponding to the air holes. A gas guide channel 302 is formed between the air duct sealing plate 303 and the outer wall of the material receiving box 3. The gas guide channel 302 on the outer side of the side wall plate of the material receiving box 3 is communicated with the gas guide channel 302 at the bottom of the material receiving box 3. The upper part of the gas guide channel 302 is connected and communicated with the negative pressure structure 5.

[0054] It should be noted that: in this embodiment, universal wheels are provided at the bottom of the material receiving box 3 to facilitate the movement of the material receiving box 3. An activity door is provided on the front side of the material receiving box 3. One side of the activity door is movably connected to the main body of the material box through a hinge. On the outer side plate of the opposite side, a locking buckle groove is provided. At the outer position corresponding to the locking buckle groove on the main body of the material receiving box 3, a movable locking buckle is provided. The movable locking buckle is correspondingly arranged with the locking buckle groove, so that the movable locking buckle can be buckled in the locking buckle groove to achieve the purpose of locking the activity door; a handle is also provided on the activity door. A communicating air guide channel 302 is provided at the bottom and outside of the material receiving box 3. An air guide joint 304 is provided on the air guide channel 302. A corrugated hose is provided on the air guide joint 304, so that one end of the corrugated hose is butt-jointed with the air guide joint 304, and the other end is hermetically communicated with the port of the material bag negative pressure pipe 503 of the negative pressure structure 5, and a certain length is reserved for the corrugated hose to facilitate the movement of the material receiving box 3 and avoid the disconnection of the air guide channel 302 and the material bag negative pressure pipe 503 of the negative pressure structure 5 due to the movement of the material receiving box 3. In this way, the negative pressure structure 5 can suck the gas between the material receiving box 3 and the material bag, so that the material bag can tightly adhere to the inside of the material receiving box 3 and avoid the material bag floating up and blocking the material falling port 103.

[0055] As Figure 3 shown, the negative pressure structure 5 includes an air separation negative pressure pipe 501, a separation chamber connecting pipe 502, a material bag negative pressure pipe 503, a wind valve actuator 504 and a throttle valve 505. One end of the air separation negative pressure pipe 501 is connected to an external negative pressure device, and the other end is fixedly connected to the top of the gas-solid separation chamber 2 and hermetically communicated with the upper port of the separation chamber connecting pipe 502. The upper end of the separation chamber connecting pipe 502 is communicated with the air separation channel 205. The lower end of the separation chamber connecting pipe 502 is hermetically communicated with one end of the throttle valve 505. The other end of the throttle valve 505 is hermetically communicated with the upper end of the material bag negative pressure pipe 503. The lower end of the material bag negative pressure pipe 503 is hermetically communicated with the air guide channel 302. The wind valve actuator 504 is arranged on the air separation negative pressure pipe 501 and is used to control the magnitude of the air extraction volume. The throttle valve 505 is used to control the on-off state of the material bag negative pressure pipe 503.

[0056] It should be noted that: in this embodiment, the air separation negative pressure pipe 501, the separation chamber connecting pipe 502 and the material bag negative pressure pipe 503 are all arranged on the same side of the gas-solid separation chamber 2 and are connected in a butt joint manner from top to bottom to form an external air extraction channel. The material bag negative pressure pipe 503 is hermetically butt-jointed with the air guide joint 304 of the air guide channel 302. Both the wind valve actuator 504 and the throttle valve 505 are electrically connected to the main control board and are controlled by the main control board. The wind valve actuator 504 is used to adjust the magnitude of the air extraction volume, and the throttle valve 505 is used to control the air extraction switch on the air guide channel 302 of the material receiving box 3.

[0057] like Figure 2 As shown, a dust extraction structure 7 is also provided on the side of the gas-solid separation chamber 2, and the dust extraction structure 7 includes a dust extraction pipe 701, a waste bag suction pipe joint 702 and a shut-off valve structure 703. One end of the dust extraction pipe 701 is sealed and connected to the solid separation chamber 203, and the other end is sealed and connected to one end of the shut-off valve structure 703. The other end of the shut-off valve structure 703 is docked with the waste bag suction pipe joint 702, and the outer end of the waste bag suction pipe joint 702 passes through the chassis 1 and extends to the outside of the chassis 1.

[0058] It should be noted that: in this embodiment, the waste bag suction pipe joint 702 extends to the outside of the chassis 1 and is connected to the external vacuum device. The external vacuum device extracts the dust-laden gas in the gas-solid separation bin 2 through the dust extraction pipe 701, so that the dust-laden gas is extracted into the dust removal device through the vacuum device and then discharged, thereby preventing the gas in the gas-solid separation bin 2 from floating out to the dust-free workshop and causing pollution to the dust-free workshop. During the operation, when the material bag in the material receiving box 3 collects a certain amount of rubber strips and needs to be taken out for processing, the negative pressure structure 5 will be closed first, so that the material bag will not be tightly attached to the inside of the material receiving box 3. At the same time, air will enter the gas-solid separation chamber 2 and the material receiving box 3 from the non-sealed interface. At this time, a certain amount of dusty gas will still remain in the material bag. If the material bag is directly taken out and packaged, the gas in the bag will be squeezed out before packaging. In this way, the dusty gas remaining in the material bag will be discharged into the dust-free workshop environment, thereby causing pollution to the dust-free workshop. The present invention will start the exhaust device after closing the negative pressure structure 5, and the dusty gas remaining in the material bag will be sucked out by the exhaust device for processing, so that what remains in the material bag is clean gas, ensuring that the gas squeezed out during packaging is clean gas, which can effectively avoid the pollution of the dust-free workshop by the residual dusty gas.

[0059] like Figure 1 As shown, a control structure 8 is also included, and the control structure 8 includes a main control board and a function button 801. The main control board is installed in the control installation slot 106. The function button 801 is electrically connected to the main control board and is arranged on the outside of the chassis 1. The main control board is electrically connected to the electrical components of each structure to control the coordinated operation of each structure.

[0060] It should be noted that: in this embodiment, the main control board is electrically connected to various cylinders, valves and other related controllers, and the start and stop status of each structure can be controlled by a set program. The function buttons 801 include a start button, an emergency stop button, an air volume adjustment button, a dust extraction start button, etc., and also include indicator lights, etc.

[0061] Working process of the present invention: The operator pulls out the material receiving box 3, then sets the material bag on the inside of the material receiving box 3, making the bag mouth of the material bag buckle reversely on the upper port of the material receiving box 3 and opening the material bag as much as possible. Then, the material receiving box 3 is pushed into the material box installation position at the lower part of the machine case 1. When the equipment is started, the control structure 8 controls the material receiving cylinder 403 to move downward, thereby driving the movable pressing cover 401 to cover the upper port of the material receiving box 3 and pressing the movable pressing cover 401 tightly through the material receiving cylinder 403. Then, the negative pressure structure 5 is started, and the air between the material bag and the inside of the material receiving box 3 in the material receiving box 3 is sucked through the negative pressure structure 5, so that the material bag can be closely attached to the inner wall of the material receiving box 3. At the same time, the rubber strip peeled off in the previous process comes out from the blanking pipeline 9 and enters the gas-solid separation bin 2. The dusty gas coming out together will move upward under the action of the suction force and enter the gas separation bin 202, and then be discharged from the gas separation negative pressure pipe 501 through the gas separation channel 205 to the gas treatment device for treatment and then discharged after being qualified; while the rubber strip directly falls from the solid separation bin 203 through the blanking port 103 into the material bag in the material receiving box 3. When the rubber strip in the material bag reaches a certain amount, the previous process stops transmitting the rubber strip to the blanking pipeline 9, and the operator closes the external negative pressure device of the negative pressure structure 5, so that the adsorption force of the inner side wall of the material receiving box 3 on the material bag can be released. Then, the control structure 8 controls the start of the dust extraction structure 7 to suck the gas in the gas-solid separation bin 2 and the material receiving box 3, so that there is no residual gas with dust particles in the material receiving box 3. Then, the control structure 8 controls the start of the baffle pushing cylinder 602 and drives the movable baffle 601 to move forward, so that the movable baffle 601 closes the blanking port 103. Then, the control structure 8 controls the start of the material receiving cylinder 403 to drive the movable pressing cover 401 to move upward, so that the movable pressing cover 401 leaves the upper port of the material receiving box 3. At this time, the operator can pull out the material receiving box 3, open the movable door, package the material bag and take it away for treatment, and then re-sleeve a new material bag to enter the next round of repetitive operation process. The waste rubber strip collecting equipment with pollution prevention of the present invention uses the same external negative pressure device, which can realize the suction of the gas in the material receiving box 3, so that the material bag can be closely attached to the inner wall of the material receiving box 3, avoiding being pulled by the internal suction force and floating to the blanking port 103, thereby causing the blockage of the blanking port 103; it can also realize the suction operation of the dusty gas in the gas separation bin 202, so that the user does not need to purchase multiple negative pressure devices, reducing costs; furthermore, the suction force of this negative pressure structure 5 also plays a role in preventing the rubber strip from adhering to the blanking pipeline and avoiding the blockage of the blanking pipeline; the present invention can directly set the material bag in the material receiving box 3 to pack the rubber strip, without transferring the rubber strip anymore, reducing the work process, reducing the workload of the operator, improving the work efficiency, and can also suck and treat the dusty gas generated by peeling the rubber strip and moving the rubber strip, avoiding the dusty gas from entering the dust-free workshop and causing pollution to the dust-free workshop.
