Description

Technical Field

[0001] This utility model relates to the technical field of plastic product cutting devices, and in particular to a cutting device for processing plastic products. Background Technology

[0002] Traditional plastic pipe cutting devices typically employ a single-segment cutting mode, meaning that only one segment of the pipe can be cut at a time. These devices usually consist of a fixed clamping mechanism, a single cutting mechanism, and a linear feeding system. During operation, the position of the pipe needs to be adjusted segment by segment manually or mechanically to achieve multiple cuts.

[0003] In mass production scenarios, this mode has significant efficiency bottlenecks: for example, the need to repeatedly execute the "positioning-cutting-returning-repositioning" cycle process results in a significant increase in processing time for a single tube. More importantly, traditional equipment cannot achieve simultaneous cutting of multiple tubes of different lengths. When multiple specifications of tubes need to be produced, multiple independent cutting processes must be completed, which not only increases the number of equipment start-ups and shutdowns and energy consumption, but also causes fluctuations in cutting accuracy due to repeated positioning, which is especially prone to dimensional deviations in the processing of high-precision plastic products.

[0004] Therefore, to address the issue of inconvenience in cutting multiple sections of tubular material of different lengths at once in high-precision plastic product processing scenarios, a cutting device for plastic product processing can be designed. When using this cutting device, when cutting plastic tubular products, it is necessary to ensure that the total length of the tube exceeds the length of the external arc-shaped clamps on both sides. During operation, the tube is inserted into the feed port on one side of the translation slide, so that its bottom contacts the upper surface of the connecting slide. Then, the lifting mechanism is activated to extend, and the lifting frame drives multiple sets of arc-shaped clamps to move downwards, with their inner walls fitting against the top of the tube. After the cutting operation starts, the translation mechanism is activated to drive the flat... The sliding block moves horizontally, driving the clamped tube forward along the cutting direction. When the tube passes the high-speed rotating cutting blade, because the cutting blade and multiple sets of connecting brackets are set one-to-one and distributed in a horizontal array, the connecting brackets only cut the tube when passing the cutting blade, without damaging the connecting block. The tube is cut sequentially by multiple sets of cutting blades during the movement. The tubes above the two middle sets of connecting blocks are finished products of the same size, while the tubes above the two side connecting blocks are finished products of shorter size. The entire device achieves the function of cutting multiple sections of tubes of different lengths at one time through the precise correspondence between the multiple sets of connecting brackets of the sliding block and the cutting blade, which is suitable for mass production scenarios. Utility Model Content

[0005] Traditional plastic pipe cutting devices typically use a single-segment cutting mode. When multiple specifications of pipe fittings need to be produced, they must be completed through multiple independent cutting processes. This not only increases the number of times the equipment is started and stopped and energy consumption, but also causes fluctuations in cutting accuracy due to repeated positioning. Therefore, when used in plastic product processing scenarios with high precision requirements, it is inconvenient to cut multiple segments of pipe materials of different lengths at one time.

During the movement, the tube is cut sequentially by multiple sets of cutting blades.

Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] Please see Figure 2 and Figure 4 This utility model provides an embodiment of a cutting device for processing plastic products, including a cutting platform 1, a driving mechanism inside the cutting platform 1, and multiple sets of cutting blades 2. Multiple sets of cutting blades 2 are rotatably arranged through the upper surface of the cutting platform 1. A translation slide 3 is arranged above the cutting platform 1. Translation mechanisms are symmetrically arranged on both sides of the bottom of the translation slide 3. Multiple sets of connecting slides 4 are arranged between the two sides of the translation slide 3. Multiple sets of connecting brackets 5 are arranged inside the translation slide 3. The two sets of connecting slides 4 on both sides are fixedly connected to the two sides of the inner wall of the translation slide 3. The two ends of the two sets of connecting slides 4 in the middle are fixedly connected to the adjacent connecting slides 4 through the connecting brackets 5. Multiple sets of arc-shaped clamps 6 are arranged above each connecting slide 4. A lifting mechanism is arranged between the arc-shaped clamps 6 and the top of the translation slide 3. A feed port 7 is opened through both ends of the translation slide 3. The multiple sets of cutting blades 2 and the multiple sets of connecting brackets 5 are arranged one-to-one and distributed in a horizontal array.

[0019] Please see Figure 4 and Figure 6 Each set of connecting slides 4 has an arc-shaped groove on its upper surface. Each set of arc-shaped clamps 6 and each set of arc-shaped grooves are equipped with rubber friction pads 8. The rubber friction pads 8 provide sufficient friction to prevent the tube from sliding and also act as a buffer to avoid excessive clamping force from damaging the tube. Each set of arc-shaped clamps 6 has symmetrical and sliding guide posts 9 on both sides. The lower end of each set of guide posts 9 is fixedly connected to one side of the upper surface of the connecting slide 4. The arc-shaped clamps 6 can achieve smooth lifting and lowering movement through the guide posts 9 on both sides.

[0020] Please see Figure 5 and Figure 6The lifting mechanism includes an electrically controlled lifting rod 10 and a lifting frame 11. Two sets of electrically controlled lifting rods 10 are fixedly installed through the top of the sliding slide 3. The lifting frame 11 is installed inside the sliding slide 3. The telescopic ends of the two sets of electrically controlled lifting rods 10 are fixedly connected to the two sides of the top surface of the lifting frame 11. The tops of multiple sets of arc-shaped clamps 6 are fixedly connected to the inner top wall of the lifting frame 11. When the two sets of electrically controlled lifting rods 10 at the top of the sliding slide 3 are activated to extend, the lifting frame 11 is driven to descend smoothly. The lifting mechanism also includes a slider 12 and a slide groove 13. The sliders 12 are symmetrically and fixedly installed on both sides of the bottom of the lifting frame 11. The inner walls of the sliding slide 3 are symmetrically provided with slide grooves 13 that are compatible with the sliders 12. The sliders 12 are embedded and slidably installed inside the slide grooves 13. When the electrically controlled lifting rods 10 extend, the lifting frame 11 descends smoothly along the inner wall slide groove 13. The multiple sets of arc-shaped clamps 6 on the inner top wall of the lifting frame 11 move downward accordingly.

[0021] Please see Figure 1 and Figure 3 The translation mechanism includes a translation slide 14 and a movable slide 15. Two sets of translation slides 14 are fixedly installed on both sides of the top of the cutting platform 1. Each set of translation slides 14 has a movable slide 15 connected to its output end. The movable slides 15 on both sides are fixedly connected to the bottom sides of the translation slide 3. The translation slide 3 is installed above the cutting platform 1, and its bottom sides are connected to the translation slides 14 on both sides of the cutting platform 1 through the translation mechanism to achieve horizontal movement. The drive mechanism includes a drive motor 16, a drive wheel 17, a transmission belt 18, a driven shaft 19, and a driven wheel 20. An active motor 16 is fixedly installed on one side inside the platform 1. An active wheel 17 is installed at the output end of the active motor 16. A driven shaft 19 is rotatably installed inside the cutting platform 1. A driven wheel 20 is fixedly installed on one side end of the driven shaft 19. A transmission belt 18 is sleeved on the outside of the active wheel 17 and the driven wheel 20. Multiple sets of cutting blades 2 are fixedly installed on the side wall of the driven shaft 19. When the active motor 16 is started, the active wheel 17 is driven to rotate. The driven wheel 20 on the driven shaft 19 is driven to rotate via the transmission belt 18, thereby driving multiple sets of cutting blades 2 fixed on the side wall of the driven shaft 19 to rotate synchronously at high speed.

[0022] When using this cutting device for processing plastic products, the working principle of the cutting device is as follows: the cutting blade 2 is rotated at high speed through the drive mechanism inside the cutting platform 1: the active motor 16 drives the active wheel 17 to rotate, and drives the driven wheel 20 on the driven shaft 19 to rotate through the transmission belt 18, thereby driving multiple sets of cutting blades 2 fixed to the side wall of the driven shaft 19 to rotate synchronously at high speed. A translation slide 3 is set above the cutting platform 1, and its bottom two sides are connected to the translation slides 14 on both sides of the cutting platform 1 through the translation mechanism to achieve horizontal movement. Multiple sets of connecting slides 4 are distributed inside the translation slide 3. The two side connecting slides 4 are fixed to the inner wall of the translation slide 3, and the middle connecting slide 4 is connected to the adjacent slide through the connecting bracket 5 to form a stable support structure.

[0023] When cutting plastic tubular products, ensure that the total length of the tube exceeds the length of the external arc-shaped clamps 6 on both sides. During operation, insert the tube into the feed port 7 on one side of the sliding slide 3, so that its bottom contacts the rubber friction pad 8 in the arc-shaped groove on the upper surface of the connecting slide 4. Then, start the lifting mechanism: the two sets of electrically controlled lifting rods 10 at the top of the sliding slide 3 extend, driving the lifting frame 11 to descend smoothly along the inner wall groove 13. The multiple sets of arc-shaped clamps 6 on the inner top wall of the lifting frame 11 move downwards accordingly, and the rubber friction pads 8 on their inner walls fit against the top of the tube. Under the guidance of the limiting guide post 9, a stable clamping is completed. At this time, the rubber friction pads 8 provide sufficient friction to prevent the tube from sliding and also play a buffering role to avoid excessive clamping force from damaging the tube.

[0024] When the cutting operation is started, the translation slide 14 drives the translation slide 3 to move horizontally through the moving slide 15, which in turn moves the clamped tube along the cutting direction. When the tube passes the high-speed rotating cutting blade 2, since the cutting blade 2 and multiple sets of connecting brackets 5 are set one-to-one and distributed in a horizontal array, the connecting brackets 5 only cut the tube when passing the cutting blade 2, without damaging the connecting slide 4. During the movement, the tube is cut by multiple sets of cutting blades 2 in sequence. The tubes above the two middle sets of connecting slides 4 are finished products of the same size, while the tubes above the two side connecting slides 4 are finished products of shorter size.

[0025] After the cutting is completed, the sliding slide 3 moves to one side of the cutting platform 1, the electric lifting rod 10 retracts and pulls the lifting frame 11 up, and the arc-shaped clamp 6 disengages from the pipe body. At this time, the cut pipe material can be easily taken out. The entire device realizes the function of cutting pipe materials of different lengths in one go by accurately corresponding the multiple sets of connecting brackets 5 of the sliding slide 3 with the cutting blade 2.

[0026] This device achieves multi-segment synchronous cutting of plastic tubular products through the corresponding arrangement of multiple cutting blades 2 and connecting brackets 5, improving processing efficiency. The coordinated design of the arc-shaped clamp 6 and the rubber friction pad 8 ensures clamping stability and avoids damage to the tube body. The synergistic effect of the translation slide 3 and the translation mechanism ensures the smoothness of the cutting process. The efficient transmission design of the drive mechanism ensures the continuous high-speed operation of the cutting blades 2. The integrated control system of the device realizes the full-process automated control of clamping, movement and cutting, reducing the difficulty of manual operation and improving processing accuracy and safety. These designs work together to make the device exhibit efficient, accurate and stable cutting performance in plastic product processing, and is suitable for mass production scenarios.

[0027] Through the above steps, when using this cutting device for processing plastic products, when cutting plastic tubular products, it is necessary to ensure that the total length of the tube exceeds the length of the outer arc-shaped clamps 6 on both sides. During operation, the tube is inserted into the feed port 7 on one side of the translation slide 3, so that its bottom contacts the upper surface of the connecting slide 4. Then, the lifting mechanism is activated to extend, and the lifting frame 11 drives multiple sets of arc-shaped clamps 6 to move downward, with their inner walls fitting against the top of the tube. When the cutting operation is started, the translation mechanism is activated to drive the translation slide 3 to move horizontally, driving the clamped tube to advance along the cutting direction. When the tube passes the high-speed rotating cutting blade 2, since the cutting blade 2 and multiple sets of connecting brackets 5 are respectively set one-to-one and horizontally... The array is distributed so that when the connecting bracket 5 passes the cutting blade 2, it only cuts the tube material without damaging the connecting slide 4. During the movement, the tube is cut sequentially by multiple sets of cutting blades 2. The tube material above the two sets of connecting slides 4 in the middle is a finished product of the same size, while the tube material above the connecting slides 4 on both sides is a finished product of a shorter size. After the cutting is completed, the sliding slide 3 moves to one side of the cutting platform 1, and the lifting mechanism is activated to retract and pull the lifting frame 11 to rise. Multiple sets of arc-shaped clamps 6 then detach from the tube material, and the cut tube material can be easily removed. The entire device achieves the function of cutting tube materials of different lengths in one go through the precise correspondence between the multiple sets of connecting brackets 5 of the sliding slide 3 and the cutting blade 2, which is suitable for mass production scenarios.

[0028] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
