DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] In one embodiment, see Figure 1-Figure 11A polytetrafluoroethylene recycling crusher includes two side plates 1 arranged parallel to each other, the side plates 1 are arranged in a left-right direction, a horizontally arranged support plate 4 is arranged below the left side of the side plate 1, the front and rear ends of the support plate 4 are fixedly connected to the opposite sides of the two side plates 1, and a crushing roller 11 is rotatably connected to the right side of the side plate 1, the center of the crushing roller 11 is flush with the upper surface of the support plate 4, and the left side of the crushing roller 11 is close to the right end of the support plate 4, and a crushing tooth 12 is arranged on the outside of the crushing roller 11, and the crushing roller 11 drives the crushing tooth 12 to rotate counterclockwise, so when the material moves to the right along the support plate 4, the crushing tooth 12 will crush the material The feeding scraper 7 is provided above the support plate 4 for biting and crushing, and the feeding scraper 7 is provided for reciprocating movement to the left and right, and the middle part of the feeding scraper 7 is raised to the right, and the upper and lower sides of the feeding scraper 7 are flat plates facing forward and backward, and the flat plate below the feeding scraper 7 can slide along the upper surface of the support plate 4, and a vertical plate 5 is provided in the middle part above the side plate 1, and a storage box 6 is fixedly connected to the upper end of the vertical plate 5, and the cross section of the storage box 6 is a right-angled trapezoid, and the left side of the bottom of the storage box 6 is a plane, and the right side of the bottom of the storage box 6 is an inclined surface, so the material inside the storage box 6 can be gathered toward the left side of the bottom, and a feeding port 2 is provided on the left side of the bottom of the storage box 6 5. The right side of the feed port 25 is rotatably connected to the feed baffle 26, and the feed baffle 26 can be rotated to a state facing the lower left, so that the material inside the storage box 6 can slide down to the lower left along the feed baffle 26, and an angle limiting device is set at the position where the feed baffle 26 and the feed port 25 are connected, which limits the feed baffle 26 to only rotate to a state facing the lower left. Therefore, the middle raised part of the feed scraper 7 includes an upper right inclined surface, and a guide cylindrical head 27 is set at the left end of the feed baffle 26. Therefore, when the feed scraper 7 moves to the right, the upper right inclined surface of the feed scraper 7 will contact the guide cylindrical head 27. , the feed baffle 26 will rotate counterclockwise to a horizontal state, and the feed baffle 26 will contact the flat plate above the feed scraper 7. At this time, the feed baffle 26 will block the feed port 25. Only when the feed scraper 7 moves to the left, the feed baffle 26 will rotate counterclockwise again, and the feed port 25 will again process the pouring of materials. An arc-shaped concave surface is set at the lower right corner of the middle bulge of the feed scraper 7, and the radius of the arc-shaped concave surface is slightly larger than the radius of the crushing roller 11. Therefore, the arc-shaped concave surface of the feed scraper 7 will cover the upper left corner of the crushing roller 11 after moving to the right, and the arc-shaped concave surface of the feed scraper 7 will push the material to contact the crushing roller 11.

[0027] In one case of the present embodiment, a horizontally arranged slide groove 2 is arranged on the upper left side of the side plate 1, and a sliding beam 3 arranged in a front-to-rear direction is slidably connected to the middle part of the slide groove 2. The sliding beam 3 is fixedly connected to the lower left side of the feed scraper 7. Therefore, the feed scraper 7 can achieve the effect of left and right movement through the mutual sliding of the sliding beam 3 and the slide groove 2. A reciprocating transverse movement drive assembly 13 is arranged at the left end of the side plate 1. The reciprocating transverse movement drive assembly 13 can drive the feed scraper 7 to move left and right to realize material feeding processing.

[0028] In one case of the present embodiment, the reciprocating transverse movement drive assembly 13 includes a fixed plate 15 fixedly connected to the left end of the side plate 1, the fixed plate 15 is arranged in a front-to-back direction, and the middle part of the fixed plate 15 is rotatably connected to a vertically arranged drive shaft 21, the upper end of the drive shaft 21 is fixedly connected to one end of a first connecting rod 20, the other end of the first connecting rod 20 is rotatably connected to the left end of a second connecting rod 19, the right end of the second connecting rod 19 is rotatably connected to the middle part of a vertically arranged drive rod 16, the lower end of the drive rod 16 is fixedly connected to the middle part of the upper surface of the sliding beam 3, and a fixed beam 17 arranged in a front-to-back direction is arranged directly above the sliding beam 3, the right side of the fixed beam 17 is fixedly connected to the feed scraper 7, and the middle part of the fixed beam 17 is fixedly connected to the drive rod 16 At the upper end of the fixed beam 17, the front and rear ends are provided with reinforcing ribs 18 fixedly connected to the sliding beam 3. Therefore, a U-shaped structure is formed by the fixed beam 17, the sliding beam 3 and the reinforcing ribs 18. The U-shaped structure can stably drive the feed scraper 7 to move left and right. A first drive motor 22 is provided on the lower surface of the fixed plate 15. The output shaft of the first drive motor 22 is fixedly connected to the first bevel gear 23. The first bevel gear 23 is meshed with the second bevel gear 24. The second bevel gear 24 is fixedly connected to the lower end of the drive shaft 21. Therefore, the first drive motor 22 rotates the drive shaft 21 through gear transmission. The drive shaft 21 drives the feed scraper 7 to move left and right through the first connecting rod 20 and the second connecting rod 19.

[0029] In one case of the present embodiment, the outer sleeve of the crushing roller 11 is provided with a C-shaped protective cover 8. The C-shaped protective cover 8 is a three-quarter circle, and the notch of the C-shaped protective cover 8 is located in the upper left corner. The front and rear ends of the C-shaped protective cover 8 are provided with plugs fixedly connected to the side plate 1. Therefore, the C-shaped protective cover 8 and the plug constitute a container open in the upper left corner, and the crushing roller 11 can perform material crushing processing inside the C-shaped protective cover 8. A screening plate 14 is provided below the C-shaped protective cover 8. The screening plate 14 is one-half circle. The centers of the screening plate 14, the C-shaped protective cover 8 and the crushing roller 11 are all coincident. Therefore, the screening plate 14 is located between the crushing roller 11 and the C-shaped protective cover 8. A discharge port 9 is provided at the lower right corner of the C-shaped protective cover 8. The discharge port 9 is connected to the inside of the C-shaped protective cover 8. Auxiliary shear strips 33 arranged in the front-to-back direction are provided on the inner side of the screening plate 14. When the crushing teeth 12 of the crushing roller 11 are in contact with the auxiliary shear strips 33, the discharge port 9 is connected to the inner side of the C-shaped protective cover 8. When the shear strips 33 are staggered with each other, the material can be crushed. The auxiliary shear strips 33 are evenly distributed along the center of the screen plate 14. The thickness of the auxiliary shear strips 33 gradually increases along the direction of rotation of the crushing roller 11, that is, the thickness of the auxiliary shear strips 33 gradually increases from left to right, and screen holes 32 are set between two adjacent auxiliary shear strips 33. Therefore, when the material is cut into small particles and is smaller than the screen holes 32, the small particles of material will pass through the screen holes 32 to achieve discharge processing.

[0030] In one case of this embodiment, the crushing roller 11 is provided with crushing teeth 12 on the outside, and the crushing teeth 12 along the circumference of the crushing roller 11 are arranged in an array along the axis of the crushing roller 11, and two adjacent crushing teeth 12 along the axial direction of the crushing roller 11 are arranged alternately. That is to say, the crushing teeth 12 on the rear side are slightly deflected in the clockwise direction relative to the crushing teeth 12 on the front side, and the crushing effect of the material can be improved by the staggered crushing teeth 12. A plurality of U-shaped support legs 10 are arranged below the side plate 1, and the entire crusher is supported by the support legs 10, and a main shaft 30 arranged in a front-to-rear direction is rotatably connected to the upper end of the rightmost support leg 10, and the front and rear sides of the main shaft 30 are rotatably connected to the side plate 1, and the middle part of the main shaft 30 is fixedly connected to the crushing roller 11, and the axis line of the crushing roller 11 is arranged colinearly with the axis line of the main shaft 30, and a second drive motor 28 is arranged on the front side of the support leg 10, and the output shaft of the second drive motor 28 is fixedly connected to the third bevel gear 29, and the third bevel gear 29 is meshed with the fourth bevel gear 31, and the fourth bevel gear 31 is fixedly connected to the front end of the main shaft 30, so that the second drive motor 28 can rotate the main shaft 30 through gear transmission, thereby causing the crushing roller 11 to rotate counterclockwise.

[0031] During the implementation of this embodiment, the first drive motor 22 is first started, and the first drive motor 22 drives the feed scraper 7 to move to the right. The feed scraper 7 pushes the feed baffle 26 to rotate clockwise, and the feed baffle 26 blocks the feed port 25. At this time, the first drive motor 22 is stopped, and the polytetrafluoroethylene material to be recycled is placed in the storage box 6. At this time, the entire equipment can be prepared for crushing processing.

[0032] The second drive motor 28 is started, and the second drive motor 28 drives the crushing roller 11 to rotate counterclockwise through the gear transmission, and the first drive motor 22 is started again, and the first drive motor 22 drives the feed scraper 7 to move left and right. When the feed scraper 7 moves to the left, the feed scraper 7 is disengaged from the feed baffle 26, and the feed baffle 26 rotates counterclockwise, and the feed port 25 is opened. At this time, the material inside the storage box 6 rolls along the feed baffle 26 to the support plate 4. When the feed scraper 7 moves to the right, the arc-shaped concave part of the feed scraper 7 contacts the material, and the material The material is pushed to the right and contacts the crushing roller 11. At this time, the material is crushed and processed. If the material is not crushed in time, it will be piled up upwards. When the feed scraper 7 moves to the far right, the material that has not completed the crushing process will accumulate in the depression between the inclined surface on the upper right of the feed scraper 7 and the arc surface on the upper left of the crushing roller 11. When the feed scraper 7 moves to the left, these materials that have not completed the crushing will fall on the support plate 4 again and wait for the second crushing process. At the same time, after the feed scraper 7 moves to the left, the feed port 25 will process the feed again.

[0033] After the crushing teeth 12 and the support plate 4 have initially crushed the material, small particles of material will enter between the crushing roller 11 and the screen plate 14. The thickness of the auxiliary shear strips 33 is designed to gradually increase from left to right. Therefore, when the crushing teeth 12 drive the material to rotate counterclockwise along the screen plate 14, the crushing teeth 12 will continue to cooperate with the auxiliary shear strips 33 of different thicknesses to complete the crushing process of the material. As the thickness of the auxiliary shear strips 33 gradually increases, the material is gradually crushed into smaller particles, thereby realizing multi-stage crushing processing. The rotation of the crushing teeth 12 will drive the material and gas inside the C-shaped protective cover 8 to rotate counterclockwise, and the material will be subjected to centrifugal force. When the particle size of the material meets the size of the screen hole 32, the material will pass through the screen hole 32 and move between the screen plate 14 and the C-shaped protective cover 8 and continue to move counterclockwise. When the material moves to the discharge port 9, the material will be thrown out, thereby realizing the unloading process.

[0034] The present invention is applicable to a polytetrafluoroethylene recovery crusher, which continuously pushes the material toward the crushing roller 11 by setting a feeding scraper 7 with a raised middle portion, thereby achieving an automatic feeding effect, so that the operator only needs to pour the material into the storage box 6, thereby improving the safety of the crusher.

[0035] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
