DETAILED DESCRIPTION

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0026] like Figure 1-Figure 6 As shown, a cable protection tube production device of the utility model comprises a mounting support frame 1; the mounting support frame 1 is equipped with a driving assembly for processing cable protection tube raw materials, the upper surface of the mounting support frame 1 is fixedly connected with a feed shell 11 for feeding cable protection tube raw materials, and the top of the feed shell 11 is rotatably connected with a rotating baffle 12;

[0027] A screening cylinder 36 is fixedly connected to one side of the feed shell 11 , and a plurality of cutting blades 362 are fixedly connected to the inner wall of the screening cylinder 36 .

[0028] The driving assembly can provide power for the cable protection tube raw material, realize the transportation and crushing of the cable protection tube raw material, and the setting of the rotating baffle 12 can prevent the cable protection tube raw material from being thrown out of the feed shell 11 during the crushing process, causing harm to the surrounding staff. Particles with qualified sizes can directly pass through the screening cylinder 36 and enter the discharge box 16 for collection. Larger particles will still be placed in the screening cylinder 36 and slowly pushed to the cutting blade 362. The cutting blade 362 can cut the larger particles of the cable protection tube raw material again. After cutting, the particles can leak out along the screening cylinder 36 and be crushed again by the cutting blade 362, further ensuring that the particles of the cable protection tube raw material can meet the preset standards.

[0029] Specifically, the feed shell 11 is rotatably connected to a spiral push cylinder 34 near the middle of the bottom position, and the spiral push cylinder 34 extends into the screening cylinder 36. The end of the spiral push cylinder 34 away from the feed shell 11 is fixedly connected to a grinding column 35. The inner wall of the screening cylinder 36 is fixedly connected to an inner grinding cylinder 361, and the inner grinding cylinder 361 is placed on the side of the cutting disc 362 away from the feed shell 11.

[0030] The spiral push cylinder 34 can continuously push the cable protection tube raw materials to the preset position. Those that meet the standard size will pass through the screening cylinder 36 during the pushing process, and those that do not meet the standard will be pushed to the cutting blade 362 for secondary crushing, further ensuring that the cable protection tube raw material particles can meet the preset standards.

[0031] The grinding column 35 can cooperate with the inner grinding cylinder 361 to grind the cable protection tube raw material. If the particles of the cable protection tube raw material are too large to enter between the grinding column 35 and the inner grinding cylinder 361, they will be cut back and forth by the cutting blade 362 until they can enter between the grinding column 35 and the inner grinding cylinder 361 or pass through the screening cylinder 36.

[0032] Specifically, the second spiral pushing shaft 37 is fixedly connected to the side of the grinding column 35 away from the spiral pushing cylinder 34 .

[0033] After being ground by the grinding column 35 , the ground cable protection tube raw material is pushed by the grinding column 35 to avoid accumulation of the cable protection tube raw material, so that the ground cable protection tube raw material can pass through the screening cylinder 36 more quickly.

[0034] Specifically, the first drive motor 2 is fixedly installed on one side of the mounting support frame 1, and a crushing wheel 23 is rotatably connected to the middle of the feed shell 11. A through shaft is fixedly connected to the middle of the crushing wheel 23. The through shaft rotates and penetrates the side wall of the feed shell 11. One end of the through shaft is placed outside the feed shell 11 and is fixedly connected to a connecting pulley 22. The connecting pulley 22 is connected to the output end of the first drive motor 2 through a driving belt 21.

[0035] The first drive motor 2 is turned on, and the output end of the first drive motor 2 drives the connecting pulley 22 to rotate through the driving belt 21. The connecting pulley 22 drives the crushing wheel 23 disposed in the feed shell 11 to rotate through the through shaft. The crushing wheel 23 can crush the larger cable protection tube raw materials during the rotation process.

[0036] Specifically, the driving assembly includes a second driving motor 3, the output end of the second driving motor 3 is connected to a transmission member 31, the transmission member 31 is connected to a reducer 32, the reducer 32 is fixedly connected to the upper surface of the mounting support frame 1, and is placed on one side of the feed shell 11, the output end of the reducer 32 is fixedly connected to a driving shaft 33, one end of the driving shaft 33 away from the reducer 32 extends into the feed shell 11, and one end of the driving shaft 33 placed in the feed shell 11 is fixedly connected to the inner wall of the spiral driving cylinder 34.

[0037] The second drive motor 3 is turned on, and the output end of the second drive motor 3 transmits power to the reducer 32 through the transmission member 31 (the transmission member 31 and the reducer 32 are both prior art and are not described in detail here). The output end of the reducer 32 drives the driving shaft 33 to rotate stably, and the driving shaft 33 drives the spiral push cylinder 34 to rotate during the rotation process. The spiral push cylinder 34 can push the crushed cable protection tube raw material to the upper surface of the screening cylinder 36 when rotating.

[0038] Specifically, a discharge box 16 is fixedly connected to the bottom of the mounting support frame 1 , and the discharge box 16 is placed below the screening cylinder 36 . An outer cover 13 is provided above the screening cylinder 36 , and the outer cover 13 is fixedly connected to the mounting support frame 1 .

[0039] Particles of qualified size can directly pass through the screening cylinder 36 and enter the discharge box 16 for collection. The setting of the outer cover 13 can protect the surrounding staff and avoid the phenomenon of particles being thrown out when screening the cable protection tube raw materials.

[0040] Working principle: When processing raw materials, first place the larger raw materials into the feed shell 11, turn on the first drive motor 2, and the output end of the first drive motor 2 drives the connecting pulley 22 to rotate through the driving belt 21, and the connecting pulley 22 drives the crushing wheel 23 placed in the feed shell 11 to rotate through the through shaft. The crushing wheel 23 can crush the larger cable protection tube raw materials during rotation. The setting of the rotating baffle 12 can prevent the cable protection tube raw materials from being thrown out of the feed shell 11 during the crushing process, causing harm to the surrounding staff.

[0041] The second drive motor 3 is turned on, and the output end of the second drive motor 3 transmits power to the reducer 32 through the transmission member 31 (the transmission member 31 and the reducer 32 are both existing technologies and are not described in detail here). The output end of the reducer 32 drives the driving shaft 33 to rotate stably. The driving shaft 33 drives the spiral push cylinder 34 to rotate during the rotation process. The spiral push cylinder 34 can push the crushed cable protection tube raw material to the upper surface of the screening cylinder 36 when rotating. Particles with qualified sizes can directly pass through the screening cylinder 36 and enter the discharge box 16 for collection, and larger particles will still be placed in the screening cylinder 3. 6 is slowly pushed to the cutting blade 362, and the cutting blade 362 can cut the cable protection tube raw material with larger particles again. The particles after cutting can leak out along the screening cylinder 36. If there are still unqualified ones, they will enter between the inner grinding cylinder 361 and the grinding column 35 under the continuous pushing of the spiral pushing cylinder 34. The grinding column 35 rotates synchronously with the spiral pushing cylinder 34 to grind the plastic particles placed between the inner grinding cylinder 361 and the grinding column 35 into smaller particles. By crushing the cable protection tube raw material for many times, it is beneficial to improve the quality of the cable protection tube produced in the next process.
