Description

Technical Field

[0001] This utility model relates to the field of plastic pellet processing technology, specifically to a plastic pellet processing equipment with equal-spacing pellet cutting function. Background Technology

[0002] In the plastics processing industry, plastic pellets are the core raw material for plastic product manufacturing. Their processing quality directly affects the stability of downstream molding processes such as injection molding and extrusion, as well as the final product quality. With the continuous expansion of plastic application scenarios, the market has put forward higher requirements for the diversity of plastic pellet specifications and processing precision. However, traditional equal-spacing plastic pellet processing equipment cannot process plastic strips of different thicknesses in long-term use. The cut plastic strips are not uniform enough, and the cutting stability is poor. Therefore, a plastic pellet processing equipment with equal-spacing function is needed.

[0003] Existing plastic pelletizing equipment with equal-spacing cutting function has a fixed spacing set at the factory, which can only adapt to plastic strips of a single thickness. When processing plastic strips of different thicknesses, the entire conveying or cutting assembly must be replaced, which not only increases the equipment purchase cost but also prolongs the changeover time, seriously affecting production efficiency. Traditional equipment often lacks precise limiting devices for plastic strips. When processing multiple plastic strips simultaneously, the plastic strips are prone to shifting to both sides due to equipment vibration and conveyor speed fluctuations, and even overlapping of adjacent plastic strips, resulting in uneven cutting. The clamping components of traditional equipment mostly adopt a fixed height design, which cannot quickly adapt to plastic strips of different thicknesses. For thicker plastic strips, insufficient clamping force can easily lead to conveyor slippage, increasing the cutting length deviation; for thinner plastic strips, excessive clamping force can easily cause the plastic strip to be squeezed and deformed, affecting the dimensional accuracy of the plastic pellets. Therefore, there is an urgent need for plastic pelletizing equipment with equal-spacing cutting function. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a plastic pellet processing equipment with equal-spacing pelletizing function, to solve the problem that existing plastic pellet processing equipment with equal-spacing function has a fixed spacing set at the factory, which can only adapt to plastic strips of a single thickness. When processing plastic strips of different thicknesses, the entire conveying or cutting assembly needs to be replaced, which not only increases the equipment purchase cost but also prolongs the changeover time, seriously affecting production efficiency. Traditional equipment often does not have a precise limiting device for plastic strips. When processing multiple plastic strips at the same time, the plastic strips are prone to shifting to both sides due to equipment vibration and conveying speed fluctuations, and even the phenomenon of adjacent plastic strips overlapping, resulting in uneven cutting. The clamping assembly of traditional equipment often adopts a fixed height design or is adjusted by a manual knob, which cannot adapt to plastic strips of different thicknesses. For thicker plastic strips, insufficient clamping force can easily lead to conveying slippage, increasing the cutting length deviation; for thinner plastic strips, excessive clamping force can easily cause the plastic strip to be squeezed and deformed, affecting the dimensional accuracy of the plastic pellets.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a plastic pellet processing equipment with equal-spacing pelletizing function, comprising a workbench, a support frame provided on the top of the workbench, a lead screw installed on the inner wall of the support frame, a handle provided at one end of the lead screw, a slider installed at one end of the lead screw, a synchronous motor provided on the side wall of the slider, a rotating rod fixedly connected to the synchronous motor via a coupling, and a conveying roller provided at one end of the rotating rod.

[0006] The support frame has a telescopic rod at its bottom, an elastic spring installed on the outer wall of the telescopic rod, a support plate fixedly connected to the bottom of the telescopic rod, a roller installed on the inner wall of the support plate, and a movable block installed on the side wall of the support plate.

[0007] The support frame has a fixing frame on its side wall, and the fixing frame has a slot on its side wall. The fixing frame has an mounting plate installed on its inner wall. The mounting plate has a limit roller movably connected to its side wall. The mounting plate has a return spring fixedly connected to its inner wall. One end of the return spring has a buckle. The fixing frame has a magnetic block on its inner wall and the bottom of the mounting plate. The support frame has a roller cutter on its inner wall.

[0008] Preferably, the lead screw is movably connected to the slider, and the lead screw is threadedly connected to the support frame.

[0009] Preferably, the conveying roller forms a rotating structure with the slider via a rotating rod, and the slider is engaged with the support frame.

[0010] Preferably, the support plate forms a telescopic structure with the support frame via a telescopic rod, and the telescopic rod is sleeved with an elastic spring.

[0011] Preferably, the roller is movably connected to the support plate, and the support plate forms a sliding structure with the support frame through a moving block.

[0012] Preferably, the buckle forms a telescopic structure with the mounting plate via a reset spring, and the buckle is inserted into the slot.

[0013] Preferably, the mounting plate is snapped into the fixing frame via a buckle, and the fixing frame is magnetically connected to the mounting plate via a magnetic block.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model, through the design of a lead screw, handle, slider, synchronous motor, rotating rod, conveying roller, and roller cutter, addresses the limitations of traditional equipment where the cutting spacing is fixed and cannot be adjusted, making it difficult to adapt to the production needs of plastic granules of different specifications. In contrast, this utility model allows adjustment of the distance between the conveying roller and the roller cutter by simply rotating the handle to drive the lead screw, thus accommodating plastic strips of different thicknesses. Furthermore, adjusting the rotation speed of the roller cutter allows for adjustment of the cutting length of the plastic granules. This achieves both the adaptation of conveying plastic strips of different thicknesses and the precise cutting of plastic granules of different lengths at equal intervals, significantly improving the versatility and processing accuracy of the equipment. 2. This utility model, through the setting of a telescopic rod, elastic spring, support plate, roller, and moving block, pushes the roller upward, causing the support plate to slide upward using the moving block. At the same time, it causes the support plate to retract and the elastic spring to compress, then places the plastic strip on the conveying roller. Then, the roller is released, and the elastic spring returns to its original position, causing the roller to move downward. Using the roller, plastic strips of different thicknesses can be pressed together, preventing the plastic strip from shifting due to the impact force generated during the roller cutting. This ensures the stability of the plastic strip during the cutting process and avoids the cutting length deviation caused by the plastic strip shifting. Stable cutting of plastic strips of different specifications can be achieved without additional adjustment of the pressing structure, improving the overall adjustment efficiency and processing versatility of the equipment. 3. This utility model uses a fixed frame, slot, mounting plate, limiting roller, return spring, buckle, and magnetic block. The limiting roller can be installed using the buckle and magnetic block. The groove above the limiting roller can prevent the plastic strip from shifting to both sides, ensuring that the plastic strip stays on the preset conveying path during the conveying process. This prevents deviation during conveying, which would affect the uniformity of cutting and ensure that the cutting position of each plastic strip is consistent. Ultimately, it achieves equidistant cutting of multiple plastic granules, further improving the cutting uniformity and processing stability of the equipment for multi-specification plastic strips.

Detailed Implementation

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0018] The embodiments of this utility model will be described below based on its overall structure.

[0019] Please see Figures 1-5 A plastic pellet processing device with equal-spacing pelletizing function includes a workbench 1, a support frame 2 on the top of the workbench 1, a lead screw 3 installed on the inner wall of the support frame 2, a handle 4 at one end of the lead screw 3, a slider 5 at the other end of the lead screw 3, a synchronous motor 6 on the side wall of the slider 5, a rotating rod 7 fixedly connected to the synchronous motor 6 via a coupling, a conveying roller 8 at one end of the rotating rod 7, the lead screw 3 and the slider 5 being movably connected, and the lead screw 3 being threadedly connected to the support frame 2, the conveying roller 8 forming a rotating structure with the slider 5 via the rotating rod 7, and the slider 5 being engaged with the support frame 2. When using the device, rotating the handle 4 drives the lead screw 3 to rotate. Since the lead screw 3 and the slider 5 are precisely threaded, and the slider 5 is guided and constrained by the guide bosses on both sides and the slide groove of the support frame 2, the rotational motion of the lead screw 3 is converted into the linear movement of the slider 5 along the slide groove. During the movement of the slider 5, it will synchronously drive the conveyor roller 8 connected to it to adjust its position. The distance between the conveyor roller 8 and the roller cutter 21 can be adjusted. By adjusting the speed of the variable frequency speed control motor of the roller cutter 21, the speed of the roller cutter can reach the calculated value, thereby adjusting the cutting length of the plastic granules to meet the requirement of cutting plastic granules of different thicknesses and finished product lengths at equal intervals.

[0020] Please see Figures 1-5 A plastic pelletizing device with equal-spacing pelletizing function includes a support frame 2 with a telescopic rod 9 at the bottom. An elastic spring 10 is installed on the outer wall of the telescopic rod 9. A support plate 11 is fixedly connected to the bottom of the telescopic rod 9. A roller 12 is installed on the inner wall of the support plate 11. A movable block 13 is provided on the side wall of the support plate 11. The support plate 11 and the support frame 2 form a telescopic structure via the telescopic rod 9, and the telescopic rod 9 is sleeved with the elastic spring 10. The roller 12 is movably connected to the support plate 11, and the support plate 11 and the support frame 2 form a sliding structure via the movable block 13. When using the device, pushing the roller 12 upwards causes it to receive an upward force, which is then transmitted to the support plate 11 through rolling bearings at both ends. Since the support plate 11 forms a vertical guiding constraint with the sliding groove of the support frame 2 via the movable block 13, under the upward force, the support plate 11 drives the movable block 13 to slide along the frame. The groove slides smoothly upwards. As the support plate 11 slides upwards, it also retracts, simultaneously compressing the elastic spring 10. The plastic strip is then placed on the conveying roller 8, and the roller 12 is released. The elastic spring 10 then uses its elasticity to push the telescopic rod 9, causing the support plate 11 to move downwards. As the support plate 11 moves downwards, the roller 12 below it moves downwards synchronously until the silicone elastic layer of the roller 12 is in close contact with the upper surface of the plastic strip. When there are slight fluctuations in the thickness of the plastic strip, the elastic spring 10 will automatically adjust the clamping force through its own compression change to ensure that the roller 12 always maintains close contact with the surface of the plastic strip, achieving adaptive clamping. This avoids the problem of insufficient local clamping force or excessive compression caused by uneven plastic strip thickness, ensuring the stable position of the plastic strip during the cutting process and avoiding cutting length deviation caused by plastic strip offset.

[0021] Please see Figures 1-5A plastic pellet processing device with equal-spacing pelletizing function includes a support frame 2 with a fixed frame 14 on its side wall. The fixed frame 14 has a slot 15 on its side wall. An mounting plate 16 is installed on the inner wall of the fixed frame 14. A limit roller 17 is movably connected to the side wall of the mounting plate 16. A return spring 18 is fixedly connected to the inner wall of the mounting plate 16. One end of the return spring 18 has a buckle 19. Magnetic blocks 20 are provided on the inner wall of the fixed frame 14 and the bottom of the mounting plate 16. A roller cutter 21 is provided on the inner wall of the support frame 2. The buckle 19 forms a telescopic structure with the mounting plate 16 via the return spring 18, and the buckle 19 is inserted into the slot 15. The mounting plate 16 is engaged with the fixed frame 14 via the buckle 19, and the fixed frame 14 is connected to the mounting plate 16 via the magnetic block 20. 6. Magnetic connection: When using the device, press the buckle 19. The buckle 19 is compressed, which in turn compresses the return spring 18. Then, insert the mounting plate 16 into the fixing frame 14. When the magnetic block 20 at the bottom of the mounting plate 16 approaches the magnetic block 20 at the bottom of the groove of the fixing frame 14, the mounting plate 16 will quickly adhere to the bottom of the groove under the action of strong magnetic attraction, achieving initial positioning. At this time, the buckle 19 on the mounting plate 16 automatically aligns with the slot 15 of the fixing frame 14. Then, release the buckle 19, and use the elastic rebound of the return spring 18 to push the buckle 19 into the slot 15 for fixing. This completes the installation of the limiting roller 17. Then, the groove above the limiting roller 17 can be used to limit the plastic strip to prevent it from shifting during conveying and affecting the uniformity of cutting.

[0022] Working principle: In use, first move the device to a suitable position, then press the buckle 19. The buckle 19 is pressed and drives the return spring 18 to compress. Then, insert the mounting plate 16 into the fixing frame 14, so that the magnetic block 20 at the bottom of the mounting plate 16 attracts and fixes with the magnetic block 20 at the bottom of the fixing frame 14. At the same time, align the buckle 19 with the slot 15. Then, release the buckle 19. Using the elastic rebound of the return spring 18, push the buckle 19 into the slot 15 for fixation. This completes the installation of the limiting roller 17. Then, place the plastic strip in the groove above the limiting roller 17 to limit the plastic strip. Then, push the roller 12 upward. The roller 12 is forceful and drives the support plate 11 to slide upward using the moving block 13. While the support plate 11 slides upward, it also causes the support plate 11 to retract, and simultaneously drives the elastic spring 10 to compress. Then, the plastic strip is released from the groove. The plastic strip is placed on the conveyor roller 8, and then the roller 12 is released. The elastic spring 10 then pushes the telescopic rod 9 to move the support plate 11 and the roller 12 downwards. The roller 12 presses the plastic strip to ensure that the plastic strip is stable during the cutting process. Then, the handle 4 is turned to drive the lead screw 3 to rotate. Since the lead screw 3 and the slider 5 are movably connected, the slider 5 moves along the groove inside the support frame 2, which synchronously drives the conveyor roller 8 to move. The distance between the conveyor roller 8 and the rotary cutter 21 is adjusted to a suitable position. Then, the rotary cutter 21 is started to perform equidistant granulation. At the same time, the cutting length of the plastic granules can be adjusted by adjusting the rotation speed of the rotary cutter 21. This completes the use of the device.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
