Description

Technical Field

[0001] This utility model relates to the technical field of cable material pelletizers, and in particular to a cable material pelletizer equipped with a multi-stage crushing mechanism. Background Technology

[0002] Cables are typically made of several or groups of conductors (at least two conductors per group) twisted together, with each group of conductors insulated from each other and often twisted around a central conductor. The entire cable is covered with a highly insulating outer layer. During the production process, cable materials are usually transported by an extruder screw, which feeds heated plastic raw material into a paste. The plastic raw material is then extruded into long strips through a die. The cable material is then cut into granules for easier processing and use in later stages.

[0003] A cable material pelletizing machine, disclosed in announcement number CN220499625U, includes a machine base and a collection bin. A frame is mounted on the top of the machine base, and a transmission component is mounted on the side wall of the frame for transmitting cables placed on the machine base surface. Limiting components are mounted on both sides of the inner wall of the machine base to limit the cutting end of the cable. A pelletizing component is mounted on the top of the frame for pelletizing the cable material ends. Multiple cutting grooves are located on the surface of the machine base below the pelletizing component. This invention uses the limiting components to limit the cable material ends, and the pelletizing component prevents the cable material from shifting position during cutting, thus improving cutting efficiency. Furthermore, the pelletizing component performs multi-segment cutting of the cable material, further improving cutting efficiency.

[0004] In the aforementioned prior art, although the cable material pelletizer has multiple parts such as a machine platform, a collection bucket, a frame, a transmission component, a limiting component, and a pelletizing component, these components are too complex and the blades are not adjustable or replaceable. Furthermore, the size of the cable material pellets is uniform and cannot be adjusted. In daily use and maintenance, more time and effort are required for cleaning, inspection, and repair, which increases the difficulty and cost of maintenance. Utility Model Content

[0005] The purpose of this utility model is to provide a cable material pelletizer equipped with a multi-stage crushing mechanism to solve the problem mentioned in the background art that the blade spacing of the existing cable material pelletizer is not adjustable and cannot be replaced.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a cable material pelletizer equipped with a multi-stage crushing mechanism, comprising a housing, support legs, a U-shaped bracket, and a first electric telescopic rod. Support legs are fixed on both sides of the bottom end of the housing, and a U-shaped bracket is fixed on the top end of the housing, with the first electric telescopic rod fixed on the top end of the U-shaped bracket.

[0007] A second electric telescopic rod is fixed to one side of the top of the box, and an upper clamping plate is fixed to the top of the second electric telescopic rod. A stabilizing rod is connected to one side of the upper clamping plate through a sleeve block, and the stabilizing rod is fixed to the top of the box. A lower clamping plate is fixed to the top of the box below the upper clamping plate. A fixing plate is fixed to the bottom of the first electric telescopic rod, and connecting rods are fixed to both sides of the top of the fixing plate. The connecting rods all pass through the U-shaped bracket. A tool holder is fixed to one side of the fixing plate. The tool holder has evenly arranged adjustment grooves and T-shaped grooves inside. A trapezoidal bracket is fixed to the outside of the box, and an adjustment structure is arranged inside the trapezoidal bracket. The bottom of the adjustment structure is connected to a motor frame. A rotating motor is connected inside the motor frame, and a rotating shaft is fixed to the output shaft end of the rotating motor. A friction shaft is fixed to one end of the rotating shaft.

[0008] When using the cable material pelletizer equipped with a multi-stage crushing mechanism using this technical solution, the position of the blades can be adjusted and the blades can be disassembled and replaced by using nuts and bolts.

[0009] Furthermore, the T-shaped groove and the adjusting groove are each slidably connected to a tool holder and a threaded column. The top of the threaded column is threaded with a nut, and the bottom of the threaded column is fixedly connected to the tool holder. The bottom of the tool holder is provided with a groove, and a tool is provided inside the groove. Bolts are threadedly connected inside the tool holder and the tool.

[0010] Furthermore, the adjusting groove and the T-shaped section are interconnected, and the cross-section of the tool holder is T-shaped.

[0011] Furthermore, both the upper and lower clamping plates are provided with trapezoidal notches, and the positions of the notches on the upper and lower clamping plates correspond one-to-one longitudinally.

[0012] Furthermore, the interior of the box is slidably connected to a drawer, and the interior of the drawer is connected to a cable cutting bracket. The interior of the drawer is evenly connected to four partitions.

[0013] Furthermore, the adjustment structure includes a screw, which is rotatably connected to the inside of the trapezoidal bracket. A fixed head is fixed to the top of the screw, and a movable plate is threaded onto the screw. Fixed rods are fixed to both sides of the bottom end of the movable plate, and the bottom ends of the fixed rods are fixedly connected to the top of the motor outer frame.

[0014] Furthermore, the cutting tools are provided in four groups at the bottom of the tool holder, with three tools in each group.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the cable material pelletizer of this multi-stage crushing mechanism not only realizes the adjustable and replaceable blades, but also has the function of high-efficiency cutting;

[0016] By installing four rows and three columns of cutting tools on the tool holder, the cutting tools on the tool holder can be moved horizontally to the required size by tightening the nuts on the threaded column until they are loose. After that, the nuts can be tightened again until the threaded column is fixed to the tool holder. When replacing or maintaining the cutting tools, the bolts on the tool holder can be removed to replace or maintain the cutting tools. This design enables flexible adjustment and quick replacement of cutting tools, improves the versatility and flexibility of the equipment, reduces equipment downtime, and improves production efficiency.

[0017] By employing a multi-row blade design with adjustable and replaceable blades, combined with a first electric telescopic rod that uses its extension to drive the blades to cut the cable material, and a second electric telescopic rod that drives the upper clamping plate to clamp and release the cable material at the recessed positions on the upper and lower clamping plates, efficient and stable cutting of the cable material is achieved. Furthermore, the spacing between each row of blades is adjustable, allowing for different spacing settings for each row as needed, thus cutting particles of different sizes in a single pass and achieving a multi-stage crushing effect. This design improves the quality and uniformity of the granulation, while the clamping mechanism of the second electric telescopic rod ensures the stability of the cable material's position during cutting, further enhancing cutting efficiency and product quality.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] Please see Figures 1-5 An embodiment of this utility model is provided: a cable material pelletizer equipped with a multi-stage crushing mechanism, including a box body 1, support legs 101, a U-shaped bracket 2, and a first electric telescopic rod 4. Support legs 101 are fixed on both sides of the bottom end of the box body 1, and a U-shaped bracket 2 is fixed on the top end of the box body 1, and a first electric telescopic rod 4 is fixed on the top end of the U-shaped bracket 2.

[0027] The tool holder 5 is evenly provided with adjustment grooves 19 and T-shaped slides 20, and the adjustment grooves 19 and T-shaped slides 20 are interconnected. The tool holder 18 has a T-shaped cross section. The tool holder 18 and threaded column 17 are slidably connected inside the T-shaped slides 20 and adjustment grooves 19, respectively. The top of the threaded column 17 is threaded with a nut 1701, and the bottom of the threaded column 17 is fixedly connected to the tool holder 18. The bottom of the tool holder 18 is provided with a groove, and the tool 11 is provided inside the groove. The tool holder 18 and the tool 11 are threaded with bolts 1702. There are four sets of tools 11 at the bottom of the tool holder 5, and three tools are provided in each set.

[0028] Specifically, such as Figure 1 , Figure 2 , Figure 3As shown, during use, the threaded post 17 and the tool holder 18 can be loosened and fixed by turning the nut 1701. When loosened, the threaded post 17 and the tool holder 18 can be slid to adjust the tool 11. Since the tool 11 is provided with four sets at the bottom of the tool holder 5, with three in each set, the adjustment can set different spacing for each set. Subsequently, the tool 11 can be removed from the tool holder 18 by removing the bolt 1702 for replacement and maintenance.

[0029] A second electric telescopic rod 7 is fixed to one side of the top of the box body 1, and an upper clamping plate 6 is fixed to the top of the second electric telescopic rod 7. A stabilizing rod 9 is connected to one side of the upper clamping plate 6 through a sleeve block, and the stabilizing rod 9 is fixed to the top of the box body 1. A lower clamping plate 8 is fixed to the top of the box body 1 below the upper clamping plate 6. Both the upper clamping plate 6 and the lower clamping plate 8 are provided with a trapezoidal notch, and the positions of the notches on the upper clamping plate 6 and the lower clamping plate 8 are longitudinally corresponding one-to-one.

[0030] Specifically, such as Figure 1 As shown, during use, since the upper clamping plate 6 and the lower clamping plate 8 are provided with trapezoidal notches in corresponding positions, the upper clamping plate 6 can be moved to extend and retract directly above the lower clamping plate 8 by activating the second electric telescopic rod 7, which can clamp and release the cable material in the upper clamping plate 6 and the lower clamping plate 8.

[0031] The bottom end of the first electric telescopic rod 4 is fixed with a fixing plate 12, and the top two sides of the fixing plate 12 are fixed with connecting rods 3. The connecting rods 3 pass through the U-shaped bracket 2. A knife holder 5 is fixed on one side of the fixing plate 12. A drawer 15 is slidably connected inside the box 1, and a cable cutting bracket 16 is connected inside the drawer 15. Four partitions are evenly connected inside the drawer 15.

[0032] Specifically, such as Figure 1 , Figure 2 As shown, when in use, the first electric telescopic rod 4 is activated to extend and retract. Since the fixed plate 12 is connected to the bottom of the first electric telescopic rod 4, the fixed plate 12 drives the knife holder 5 to move up and down, which can cut the cable material on the cable pelletizing bracket 16. After the cable pellets are cut, they flow into the drawer 15. When the drawer 15 is full of cable pellets, the drawer 15 can be pulled out of the box 1, and then the cable pellets can be taken out.

[0033] A trapezoidal bracket 13 is fixed to the outside of the housing 1, and an adjustment structure 22 is provided inside the trapezoidal bracket 13. The bottom end of the adjustment structure 22 is connected to a motor frame 14, and a rotating motor 21 is connected inside the motor frame 14. A rotating shaft 10 is fixed to the output shaft end of the rotating motor 21, and a friction shaft 1001 is fixed to one end of the rotating shaft 10.

[0034] The adjustment structure 22 includes a screw 2201, which is rotatably connected to the inside of the trapezoidal bracket 13. A fixed head 2202 is fixed to the top of the screw 2201. A movable plate 2203 is threaded onto the screw 2201. Fixed rods 2204 are fixed on both sides of the bottom end of the movable plate 2203. The bottom end of the fixed rods 2204 is fixedly connected to the top of the motor outer frame 14.

[0035] Specifically, such as Figure 1 , Figure 4 As shown, during use, the fixed head 2202 can be screwed by rotating the shaft 10 up and down on the U-shaped bracket 2, causing the movable plate 2203 to move up and down on the screw 2201. Since the movable plate 2203 is connected to the fixed rod 2204, and the bottom end of the fixed rod 2204 is connected to the motor outer frame 14, and the motor is fixed inside the motor outer frame 14, and the motor drives the friction shaft 1001 through the rotating shaft 10, the friction shaft 1001 can be moved up and down during movement, so that the friction shaft 1001 can adapt to different sizes of cable materials.

[0036] Working Principle: In use, the cable material is first placed into the lower clamping plate 8 at the top of the housing 1. Then, the rotating motor 21 is started, driving the rotating shaft 10 and the friction shaft 1001 fixed at one end of the rotating shaft 10 to rotate synchronously. The rotation of the friction shaft 1001 and the friction on its surface feed the cable material into the corresponding cable pelletizing bracket 16 below the multi-stage crushing and cutting zone cutter holder 5. When the second electric telescopic rod 7 is started, its telescopic movement drives the upper clamping plate 6, thereby clamping the cable material at the notch on the lower clamping plate 8. Then, the first electric telescopic rod 4 is started, and its telescopic movement... The fixed plate 12 connected to the bottom end of the first electric telescopic rod 4 drives the knife holder 5 to move up and down. Since the knife holder 5 is connected to the knife seat 18 through the T-shaped slide groove 20 inside the knife holder 5, it drives the knife 11 connected to the bottom end of the knife seat 18 through the bolt 1702 to move up and down, thus completing the cutting of the cable material. After the cutting is completed, the cable material in the upper clamping plate 6 and the lower clamping plate 8 is released by the telescopic property of the second electric telescopic rod 7. When the friction shaft 1001 drives the cable material to the multi-stage crushing and cutting zone by friction, and before the first electric telescopic rod 4 makes the telescopic movement, the second electric telescopic rod 7 will use its telescopic property to clamp and fix the cable material in the upper clamping plate 6 and the lower clamping plate 8.

[0037] Secondly, if it is necessary to adjust the size of the cable material particles, the machine can be turned off first, and then the nut 1701 can be turned on to adjust the threaded column 17. When it is loose, the cutter holder 18 can be moved horizontally with the cutter 11 on the cutter holder 18 until the required size is adjusted. Then the nut 1701 can be turned on again until the threaded column 17 clamps the cutter holder 18 for further fixation. Then the machine can be restarted to cut the cable material into different sizes of particles. Since the multi-stage crushing and cutting zone has four rows of three cutters 11, and the spacing of each cutter can be adjusted, different spacing can be set for each row of cutters 11, and different sizes of particles can be cut at one time, thereby achieving the effect of multi-stage crushing. If it is necessary to repair or replace the cutter 11, the cutter 11 can be repaired or replaced by removing the bolt 1702 on the cutter holder 18.

[0038] Finally, since the rotating shaft 10 can move up and down on the U-shaped bracket 2, the movable plate 2203 can move up and down on the screw 2201 by screwing the fixed head 2202. Since the movable plate 2203 is connected to the fixed rod 2204, and the bottom end of the fixed rod 2204 is connected to the motor frame 14, the motor is fixed inside the motor frame 14, and the motor drives the friction shaft 1001 through the rotating shaft 10. When moving, the friction shaft 1001 can be moved up and down so that the friction shaft 1001 can adapt to different sizes of cable materials through friction. If the tool 11 becomes dull, the tool 11 can be replaced by disassembling the bolt 1702. At the same time, multiple drawers 15 are connected inside the box 1 so that cable particles of the same size can be inserted during cutting.
