Description

Technical Field

[0001] This invention relates to the field of waste treatment technology, specifically to a waste recycling and crushing equipment for processing rubber sealing rings. Background Technology

[0002] A rubber seal is an annular cover composed of one or more parts, fixed to one ring or washer of a bearing and in contact with or forming a narrow labyrinth gap with another ring or washer to prevent lubricating oil leakage and foreign matter intrusion. During the processing of rubber seals, a large amount of ribbon-like, strip-like, or coiled rubber waste is generated during extrusion, turning, trimming, and punching. This type of waste is characterized by high toughness, high elasticity, and continuous ribbon-like shape.

[0003] For example, a rubber waste recycling and crushing device, as disclosed in Chinese Patent Publication No. CN221834764U, includes an installation cavity. Inside the installation cavity, two symmetrically arranged rotating shafts are provided, and a drive gear meshing with each other is provided at the same end of the two rotating shafts. The outer surface of the rotating shafts is provided with a plurality of evenly distributed crushing teeth. A cooling mechanism is provided at the end of the rotating shafts away from the drive gears. The two rotating shafts rotate relative to each other by the rotation of the drive gears. At this time, rubber waste is placed between the two rotating shafts and then crushed by the crushing teeth.

[0004] In existing technical references, the rotation of two rotating shafts can drive the crushing teeth to crush rubber. However, this design only crushes the rubber waste, resulting in the crushed rubber particles still containing large pieces of material, leading to uneven crushing. At the same time, it is inconvenient to pre-treat the rubber waste, as ribbon-like, long strip-like, and filamentous rubber waste may become entangled on the crushing components, affecting the normal crushing process. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the present invention is implemented through the following technical solution: A waste recycling and crushing processing device for rubber sealing ring manufacturing includes: The machine body, and the outer shell fixedly installed at the middle of the top of the machine body, wherein a feed hopper is installed on the top of the surface of the outer shell, and a pre-treatment mechanism is installed inside the outer shell; A crushing mechanism includes a driver and an auxiliary component. The driver is installed on the side of the machine body surface, and the auxiliary component is installed in the middle of the machine body cavity. A first roller and a second roller are rotatably installed inside the machine body near the auxiliary component. The ends of the first roller and the second roller are fixedly installed to the output end of the driver via a coupling. Primary crushing teeth are fixedly connected to the outer circular surface of the first roller, and secondary crushing teeth are fixedly connected to the outer circular surface of the second roller. A semi-circular block is fixedly connected to the outer end face of the first roller. The pretreatment mechanism includes a triangular cutting blade and a right-angled connecting plate. The triangular cutting blade is fixedly installed on the top of the inner cavity of the outer shell, and the right-angled connecting plate is slidably installed on the side of the top of the machine body. A connecting ring is fixedly installed at the bottom end of the right-angled connecting plate, and an arc-shaped force-bearing component is fixedly connected to the top of the inner side of the connecting ring. The arc-shaped force-bearing component is installed directly above the semicircular block, and a V-shaped opening cutting blade is fixedly connected to the top end of the right-angled connecting plate. When the first roller rotates, the first roller can drive the semicircular block to rotate together. The rotating semicircular block contacts the arc-shaped force-bearing component at the top of the connecting ring, so that the arc-shaped force-bearing component is subjected to the upward pushing force of the semicircular block. Under the sliding connection of the right-angled connecting plate, the V-shaped opening cutting blade is pushed upward. Using the upward-facing V-shaped opening of the V-shaped cutter blade, ribbon-like rubber waste fed from the hopper enters the outer casing and falls onto the V-shaped opening of the cutter blade. Through the pushing action of the semi-circular block on the arc-shaped force-bearing component, and with the connection of the right-angle connecting plate, the V-shaped cutter blade moves upward. Combined with the contact between the surfaces of the V-shaped cutter blade and the triangular cutter blade, the V-shaped cutter blade and the triangular cutter blade move in a scissor-like motion, cutting the ribbon-like rubber waste into small segments. This pre-treatment of the rubber waste prevents entanglement. A discharge mechanism is installed at the bottom of the internal cavity of the machine.

[0006] Preferably, the primary crushing teeth are arc-shaped and are evenly distributed on the outer surface of the first roller.

[0007] Preferably, the secondary crushing teeth are triangular and are evenly distributed on the outer surface of the second roller.

[0008] Preferably, the auxiliary component includes a receiving plate, the end of which is fixedly installed to the inner wall of the machine body by bolts. The receiving plate is installed directly below the first roller. A crushing base tooth is fixedly connected to the middle of the top of the receiving plate, near the primary crushing tooth. The crushing base tooth and the primary crushing tooth are arranged alternately. A strip-shaped hole is opened at the top of the receiving plate near the crushing base tooth, and a dovetail-shaped notch is opened at the bottom of the receiving plate. By rotating the output end of the driver, the first roller can be driven to rotate, so that the primary crushing tooth is driven to rotate circumferentially by the first roller. As the cut rubber waste moves down along the receiving plate to the position of the crushing base tooth, the rotating primary crushing tooth contacts the rubber waste. The rotation of the primary crushing tooth applies a circumferential cutting force to the rubber waste, while the crushing base tooth applies a reverse pulling force to the rubber waste, thus initially crushing the rubber waste into granules.

[0009] Preferably, the receiving plate is installed at an angle, and the primary crushing teeth and dovetail notches are evenly distributed on the top of the receiving plate.

[0010] After initial crushing, the granular rubber waste continues to slide along the receiving plate towards the second roller. The output of the driver drives the second roller to rotate, causing the secondary crushing teeth to rotate along with it. The secondary crushing teeth are driven by the second roller to rotate in a circular motion. When the secondary crushing teeth match the V-shaped open cutting blade, the large pieces of material in the granular rubber waste are crushed again, achieving graded crushing and making the crushing more uniform.

[0011] Preferably, there are two right-angled connecting plates, and the two right-angled connecting plates are symmetrically installed along the central axis of the outer shell. The central axis of the first roller passes through the center of the connecting ring, and the triangular cutting blades are evenly distributed on the top of the inner cavity of the outer shell.

[0012] Preferably, the V-shaped opening cutter blade has its opening facing upwards, and the surface of the V-shaped opening cutter blade is in contact with the surface of the triangular cutter blade. When the semicircular block separates from the arc-shaped force-bearing component, the upward force on the arc-shaped force-bearing component disappears, and under the sliding connection of the right-angle connecting plate, the V-shaped opening cutter blade slides downwards under its own gravity. This not only helps to continuously cut the ribbon-like rubber waste in the future, but also makes it easier for the short pieces of rubber waste to fall from the gap between two adjacent V-shaped opening cutter blades.

[0013] Preferably, the discharge mechanism includes a support frame, which is fixedly installed at the bottom of the inner cavity of the machine body and extends to the outside of the machine body. A servo motor is fixedly installed on the side of the surface of the support frame. An active roller and a driven roller are rotatably installed on the inner side of the support frame. A rolling roller is rolled at the bend at the top of the support frame. A conveyor belt is installed between the active roller and the driven roller and near the rolling roller. A support bar is fixedly connected to the surface of the conveyor belt, and an elastic steel wire is fixedly connected to the top of the support bar.

[0014] Preferably, the end of the drive roller is fixedly installed to the output end of the servo motor via a coupling, and there are two rollers, which are symmetrically installed along the central axis of the support frame. The outer surface of the roller is in contact with the side of the conveyor belt surface.

[0015] By using a conveyor belt parallel to the receiving plate, and the conveyor belt driving the support bar and elastic steel wire to rotate, the top of the elastic steel wire extends into the inside of the strip hole, which can move the rubber material that has been initially crushed by the primary crushing teeth on the top of the receiving plate, making it easier for the initially crushed rubber material to move downward and preventing jamming.

[0016] Preferably, the support bars are evenly distributed on the surface of the conveyor belt, the elastic steel wires are installed perpendicular to the support bars, and the elastic steel wires are evenly distributed on the top of the support bars.

[0017] As the conveyor belt drives the support bars and elastic steel wires to move continuously, the tip of the elastic steel wire is inserted into the dovetail-shaped notch. The tip of the elastic steel wire comes into contact with the rubber granules inside the dovetail-shaped notch, so that the rubber granules inside the dovetail-shaped notch are subjected to the elastic pushing force of the elastic steel wire. This facilitates the falling of the rubber granules inside the dovetail-shaped notch, achieving self-cleaning and preventing blockages.

[0018] This invention provides a waste recycling and crushing processing device for rubber sealing ring manufacturing. It has the following beneficial effects: I. The waste recycling and crushing equipment for processing rubber sealing rings utilizes the rotation of the output end of the driver to drive the first circular roller to rotate, causing the primary crushing teeth to rotate circumferentially. As the cut rubber waste continues to move downwards along the receiving plate to the position of the crushing base teeth, the rotating primary crushing teeth come into contact with the rubber waste. The rotation of the primary crushing teeth applies a circumferential cutting force to the rubber waste, while the crushing base teeth apply a reverse pulling force to the rubber waste, thus initially crushing the rubber waste into granules.

[0019] II. The waste recycling and crushing equipment for this rubber sealing ring processing, after initial crushing, the rubber waste in granular form continues to slide along the receiving plate towards the second roller. The output end of the driver drives the second roller to rotate, causing the secondary crushing teeth to rotate together with the second roller. The secondary crushing teeth can be driven by the second roller to rotate in a circle. When the secondary crushing teeth match the V-shaped open cutting blade, the large pieces of material in the granular rubber waste are crushed again, achieving graded crushing and making the crushing more uniform.

[0020] 3. The waste recycling and crushing equipment for this rubber sealing ring processing utilizes the upward-facing V-shaped opening of the V-shaped cutting blade. The ribbon-like rubber waste fed from the hopper enters the outer shell and falls onto the V-shaped opening of the cutting blade. Through the pushing action of the semi-circular block on the arc-shaped force-bearing component, and with the connection of the right-angle connecting plate, the V-shaped cutting blade moves upward, causing the V-shaped cutting blade and the triangular cutting blade to move in a scissor-like motion, cutting the ribbon-like rubber waste into small segments. This pre-treatment of the rubber waste prevents entanglement.

[0021] IV. The waste recycling and crushing equipment for processing rubber sealing rings, when the semi-circular block separates from the arc-shaped force-bearing component, the top force on the arc-shaped force-bearing component disappears, and under the sliding connection of the right-angle connecting plate, the V-shaped opening cutter blade slides down under its own gravity, which not only helps to continuously cut the ribbon-like rubber waste in the future, but also makes it easy for the short rubber waste to fall from the gap between two adjacent V-shaped opening cutter blades.

[0022] 5. The waste recycling and crushing equipment for processing rubber sealing rings utilizes a conveyor belt parallel to the receiving plate. The conveyor belt drives the support bar and elastic steel wire to rotate. The top of the elastic steel wire extends into the interior of the strip hole, which can move the rubber material that has been initially crushed by the primary crushing teeth on the top of the receiving plate. This facilitates the downward movement of the initially crushed rubber material and prevents jamming.

[0023] VI. The waste recycling and crushing equipment for processing rubber sealing rings utilizes the insertion of the tip of an elastic steel wire into the interior of a dovetail-shaped notch. This allows the tip of the elastic steel wire to contact the rubber particles inside the dovetail-shaped notch, enabling the rubber particles inside the dovetail-shaped notch to be subjected to the elastic pushing force of the elastic steel wire. This facilitates the falling of the rubber particles inside the dovetail-shaped notch, achieving self-cleaning and reducing the likelihood of blockage. Attached Figure Description

[0026] 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.

[0027] For the first embodiment, please refer to... Figures 1-5 The present invention provides a technical solution: A waste recycling and crushing processing device for rubber sealing ring manufacturing includes: The machine body 1, and the outer shell 2 fixedly installed at the middle of the top of the machine body 1, the top of the outer shell 2 is equipped with a feed hopper 3, and the interior of the outer shell 2 is equipped with a pretreatment mechanism 4; The crushing mechanism 5 includes a driver 51 and an auxiliary component 52. The driver 51 is installed on the side of the surface of the machine body 1, and the auxiliary component 52 is installed in the middle of the inner cavity of the machine body 1. A first roller 53 and a second roller 54 are rotatably installed inside the machine body 1 and near the auxiliary component 52. The ends of the first roller 53 and the second roller 54 are fixedly installed to the output end of the driver 51 through a coupling. The outer circular surface of the first roller 53 is fixedly connected to a primary crushing tooth 55, and the outer circular surface of the second roller 54 is fixedly connected to a secondary crushing tooth 56. A semi-circular block 57 is fixedly connected to the outer end face of the first roller 53. The primary crushing tooth 55 is arc-shaped and is evenly distributed on the outer surface of the first roller 53.

[0028] The secondary crushing teeth 56 are triangular and are evenly distributed on the outer surface of the second roller 54.

[0029] The auxiliary component 52 includes a receiving plate 521. The end of the receiving plate 521 is fixedly installed to the inner wall of the machine body 1 by bolts. The receiving plate 521 is installed directly below the first circular roller 53. A crushing base tooth 522 is fixedly connected to the middle of the top of the receiving plate 521, near the primary crushing tooth 55. The crushing base tooth 522 and the primary crushing tooth 55 are arranged alternately. A strip-shaped hole 523 is opened at the top of the receiving plate 521 near the crushing base tooth 522. A dovetail notch 524 is opened at the bottom end of the receiving plate 521. By installing the receiving plate 521 at an angle, the rubber waste cut after falling onto the top of the receiving plate 521 is directed downwards. Move the drive 51 to start working. The rotation of the output end of the drive 51 can drive the first roller 53 to rotate, so that the primary crushing tooth 55 will be driven by the first roller 53 to rotate in a circle. As the cut rubber waste moves down along the receiving plate 521 to the position of the crushing base tooth 522, the rotating primary crushing tooth 55 contacts the rubber waste. The rotation of the primary crushing tooth 55 applies a circumferential cutting force to the rubber waste, while the crushing base tooth 522 applies a reverse pulling force to the rubber waste, so that the rubber waste can be initially crushed and crushed into granules.

[0030] The receiving plate 521 is installed at an angle. The primary crushing teeth 55 and the dovetail notch 524 are evenly distributed on the top of the receiving plate 521. The rubber waste after initial crushing is in the form of granular material and will continue to slide along the receiving plate 521 toward the position close to the second roller 54. The output end of the driver 51 drives the second roller 54 to rotate, so that the secondary crushing teeth 56 rotate together with the second roller 54. The secondary crushing teeth 56 can be driven by the second roller 54 to rotate in a circle. When the secondary crushing teeth 56 match the V-shaped opening cutter blade 45, the large pieces of material in the granular rubber waste are crushed again, realizing graded crushing and making the crushing more uniform.

[0031] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figures 1 to 7 As shown: The pretreatment mechanism 4 includes a triangular cutting blade 41 and a right-angled connecting plate 42. The triangular cutting blade 41 is fixedly installed on the top of the inner cavity of the outer shell 2. The right-angled connecting plate 42 is slidably installed on the side of the top of the machine body 1. A connecting ring 43 is fixedly installed at the bottom end of the right-angled connecting plate 42. An arc-shaped force-bearing component 44 is fixedly connected to the top of the inner side of the connecting ring 43. The arc-shaped force-bearing component 44 is installed directly above the semicircular block 57. A V-shaped opening cutting blade 45 is fixedly connected to the top of the right-angled connecting plate 42. When the first roller 53 rotates, the first roller 53 can drive the semicircular block 57 to rotate together. The rotating semicircular block 57 contacts the arc-shaped force-bearing component 44 at the top of the connecting ring 43, so that the arc-shaped force-bearing component 44 is subjected to the force of the semicircular block. The upward pushing force of 57, and the sliding connection of the right-angle connecting plate 42, pushes the V-shaped opening cutter 45 upward. With the V-shaped opening of the V-shaped opening cutter 45 facing upward, the ribbon-like rubber waste fed from the feed hopper 3 enters the outer shell 2 and falls onto the V-shaped opening of the V-shaped opening cutter 45. Through the pushing action of the semi-circular block 57 on the arc-shaped force-bearing member 44, and with the connection of the right-angle connecting plate 42, the V-shaped opening cutter 45 moves upward. Combined with the contact between the surface of the V-shaped opening cutter 45 and the surface of the triangular cutter 41, the V-shaped opening cutter 45 and the triangular cutter 41 form a scissor-like movement to cut the ribbon-like rubber waste and pre-treat the rubber waste. There are two right-angled connecting plates 42, and the two right-angled connecting plates 42 are symmetrically installed along the central axis of the outer shell 2. The central axis of the first circular roller 53 passes through the center of the connecting ring 43. The triangular cutting blades 41 are evenly distributed on the top of the inner cavity of the outer shell 2. As the semi-circular block 57 continues to rotate, when the semi-circular block 57 separates from the arc-shaped force-bearing member 44, the top force on the arc-shaped force-bearing member 44 disappears. Under the sliding connection of the right-angled connecting plates 42, the V-shaped opening cutting blades 45 slide down under their own gravity. This not only helps to continuously cut the ribbon-like rubber waste, but also makes it easier for the short pieces of rubber waste to fall from the gap between the two adjacent V-shaped opening cutting blades 45.

[0032] The opening of the V-shaped opening cutter 45 faces upward, and the surface of the V-shaped opening cutter 45 is in contact with the surface of the triangular cutter 41.

[0033] The third embodiment is based on the first and second embodiments; please refer to [link / reference]. Figures 1 to 8 As shown: The bottom of the inner cavity of the machine body 1 is equipped with a discharge mechanism 6.

[0034] The discharge mechanism 6 includes a support frame 61, which is fixedly installed at the bottom of the inner cavity of the machine body 1 and extends to the outside of the machine body 1. A servo motor 62 is fixedly installed on the side of the surface of the support frame 61. A drive roller 63 and a driven roller 64 are rotatably installed on the inner side of the support frame 61. A rolling roller 65 is rolled at the bend at the top of the support frame 61. A conveyor belt 66 is installed between the drive roller 63 and the driven roller 64 and near the rolling roller 65. A support bar 67 is fixedly connected to the surface of the conveyor belt 66. The top of 67 is fixedly connected with an elastic steel wire 68. As the triangular cutting blade 41 crushes the rubber waste, the granules fall onto the conveyor belt 66. At this time, the operator starts the servo motor 62. The rotation of the output end of the servo motor 62 can drive the active roller 63 to roll. With the support of the rolling of the driven roller 64, the conveyor belt 66 runs, which can transport the crushed rubber granules and move them out of the machine body 1 for easy recycling.

[0035] The end of the drive roller 63 is fixedly mounted to the output end of the servo motor 62 via a coupling. Two rollers 65 are symmetrically mounted along the central axis of the support frame 61. The outer surface of the rollers 65 is in contact with the edge of the conveyor belt 66. The operation of the conveyor belt 66 moves the support bar 67, causing the elastic steel wire 68 to move as well. By utilizing the contact between the outer surface of the rollers 65 and the edge of the conveyor belt 66, the rollers 65 apply pressure to the conveyor belt 66. The rolling and the rolling support of the driven roller 64 at the top of the support frame 61 on the conveyor belt 66 make the conveyor belt 66 below the receiving plate 521 tilted. The conveyor belt 66 is parallel to the receiving plate 521, and the conveyor belt 66 drives the support bar 67 and the elastic steel wire 68 to rotate. The top of the elastic steel wire 68 extends into the inside of the strip hole 523, which can move the rubber material that has been initially crushed by the primary crushing tooth 55 on the top of the receiving plate 521, so that the initially crushed rubber material can move downward.

[0036] Support bars 67 are evenly distributed on the surface of conveyor belt 66. Elastic steel wires 68 are installed perpendicular to the support bars 67 and are evenly distributed on the top of the support bars 67. As the conveyor belt 66 drives the support bars 67 and elastic steel wires 68 to move continuously, the top of the elastic steel wires 68 is inserted into the dovetail-shaped notch 524. The top of the elastic steel wires 68 can then contact the rubber granules in the dovetail-shaped notch 524, so that the rubber granules in the dovetail-shaped notch 524 are subjected to the elastic pushing force of the elastic steel wires 68, which facilitates the falling of the rubber granules in the dovetail-shaped notch 524.

[0037] When in use, first turn on the driver 51 to start working. The output end of the driver 51 rotates, which can drive the first roller 53 to rotate. When the first roller 53 rotates, the first roller 53 can drive the semi-circular block 57 to rotate together. The rotating semi-circular block 57 contacts the arc-shaped force-bearing member 44 at the top of the connecting ring 43, so that the arc-shaped force-bearing member 44 is subjected to the upward pushing force of the semi-circular block 57. Under the sliding connection of the right-angle connecting plate 42, the V-shaped opening cutter 45 is pushed upward and the rubber waste that needs to be crushed is put into the feed hopper 3. Using the upward-facing V-shaped opening of the V-shaped cutter blade 45, the ribbon-like rubber waste fed from the feed hopper 3 enters the outer casing 2 and falls onto the V-shaped opening of the V-shaped cutter blade 45. Through the pushing action of the semi-circular block 57 on the arc-shaped force-bearing member 44, and under the connection of the right-angle connecting plate 42, the V-shaped cutter blade 45 moves upward. Combined with the contact between the surface of the V-shaped cutter blade 45 and the surface of the triangular cutter blade 41, the V-shaped cutter blade 45 and the triangular cutter blade 41 move in a scissor-like manner to cut the ribbon-like rubber waste and pre-treat the rubber waste. As the semicircular block 57 continues to rotate, when the semicircular block 57 separates from the arc-shaped force-bearing component 44, the top force on the arc-shaped force-bearing component 44 disappears, and under the sliding connection of the right-angle connecting plate 42, the V-shaped opening cutter 45 slides down under its own gravity, which not only helps to continuously cut the ribbon-like rubber waste, but also makes it easier for the short rubber waste to fall from the gap between the two adjacent V-shaped opening cutter 45. Simultaneously, by using the inclined installation of the receiving plate 521, the rubber waste cut after falling onto the top of the receiving plate 521 moves downward. The driver 51 is then activated to start working. The rotation of the output end of the driver 51 drives the first roller 53 to rotate, causing the primary crushing tooth 55 to rotate circumferentially. As the cut rubber waste continues to move downward along the receiving plate 521 to the position of the crushing base tooth 522, the rotating primary crushing tooth 55 contacts the rubber waste. The rotation of the primary crushing tooth 55 applies a circumferential cutting force to the rubber waste, while the crushing base tooth 522 applies a reverse pulling force to the rubber waste. This allows for the initial crushing of the rubber waste, breaking it into granules. Furthermore, the granular rubber waste after initial crushing will continue to slide along the receiving plate 521 towards the position close to the second roller 54, and the output end of the driver 51 will drive the second roller 54 to rotate, so that the secondary crushing teeth 56 rotate together with the second roller 54. The secondary crushing teeth 56 can be driven by the second roller 54 to rotate in a circle, and when the secondary crushing teeth 56 match the V-shaped opening cutter blade 45, the large pieces of material in the granular rubber waste will be crushed again, realizing graded crushing and making the crushing more uniform. Furthermore, as the triangular cutting blade 41 crushes the rubber waste into granules that fall onto the conveyor belt 66, the operator starts the servo motor 62. The rotation of the servo motor 62's output drives the drive roller 63 to roll, and with the support of the driven roller 64, the conveyor belt 66 rotates. The rotation of the conveyor belt 66 moves the support bar 67, causing the elastic steel wire 68 to move as well. The outer surface of the rolling roller 65 contacts the edge of the conveyor belt 66, and the rolling action... The pressure roller 65 rolls the conveyor belt 66, and the driven roller 64 at the top of the support frame 61 provides rolling support for the conveyor belt 66, so that the conveyor belt 66 below the receiving plate 521 is in an inclined state. The conveyor belt 66 is parallel to the receiving plate 521, and the conveyor belt 66 drives the support bar 67 and the elastic steel wire 68 to rotate. The top of the elastic steel wire 68 extends into the inside of the strip hole 523, which can move the rubber material that has been initially crushed by the primary crushing tooth 55 on the top of the receiving plate 521, so that the initially crushed rubber material can move downward. By inserting the tip of the elastic steel wire 68 into the dovetail-shaped notch 524, the tip of the elastic steel wire 68 can come into contact with the rubber granules inside the dovetail-shaped notch 524, so that the rubber granules inside the dovetail-shaped notch 524 are subjected to the elastic pushing force of the elastic steel wire 68, which facilitates the falling of the rubber granules inside the dovetail-shaped notch 524. When the rubber granules fall onto the conveyor belt 66 and continue to operate, the crushed rubber granules are transported out of the machine body 1, making it easier to recycle them.
