Abstract
Description
Technical Field
[0001] This utility model relates to the field of polymer material manufacturing technology, and in particular to an adjustable polymer material pelletizer. Background Technology
[0002] Polymer materials, also known as high molecular weight polymers, are materials composed of high molecular weight compounds as the matrix and other additives. Their properties can be classified into rubber, fiber, plastic, high molecular weight adhesive, high molecular weight coating and high molecular weight composite materials, etc. In the preparation of high molecular weight polymers, the extruded strips from the extruder need to be pelletized using a pelletizer. During the pelletizing process, the strips are prone to shaking or jumping during cutting, resulting in poor pelletizing effect and inconsistent particle size.
[0003] To improve upon the aforementioned drawbacks, an adjustable polymer pelletizer is disclosed in the prior art, comprising a housing, a feeding chamber inside the housing, and a feeding roller rotatably connected between the side walls of the feeding chamber. This roller can limit the movement of the material strips and effectively prevent the position of the material strips from changing during the pelletizing process, thus preventing uneven particle size in the final pellets.
[0004] However, this device still has certain drawbacks in actual use. For example, the outer diameter of the material strips to be cut varies due to differences in material weight or the model of the equipment used to produce the strips. The existing device can only be used with strips of a fixed outer diameter and cannot be used with strips of different outer diameters in the same batch, thus limiting its applicability and practical performance. Therefore, it is necessary to provide an adjustable polymer material pelletizer to solve the above-mentioned technical problems. Utility Model Content
[0005] In view of the above situation and to overcome the defects of the existing technology, this utility model provides an adjustable polymer material pelletizer that can adapt and use material strips of different outer diameters in the same batch. This feature expands its application range and improves its practical performance.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0007] An adjustable polymer pelletizer includes: a housing with through slots on both the front and rear sides, multiple material strips arranged inside the through slots; an electric push rod fixedly connected to the rear top of the housing; a bracket fixedly sleeved on the outer wall of the electric push rod, the top of the bracket being fixedly connected to the housing; a cutter fixedly connected to the bottom end of the electric push rod; and a guide assembly on the outer side of the material strips, the guide assembly including: a circular roller located below the material strips; multiple conical annular grooves evenly formed on the outer wall of the circular roller; the inner wall of the conical annular grooves abutting against the material strips; and a [missing information - likely a design feature] above the conical annular grooves. The abutment roller has its bottom end pressed against the material strip. A U-shaped plate is provided above the abutment roller, and the U-shaped plate is rotatably connected to the abutment roller via a rotating shaft. A vertical rod is fixedly connected to the top of the U-shaped plate, and a horizontal plate is fixedly sleeved on the outer wall of the vertical rod. A compression spring is fixedly connected to the top of the horizontal plate, and a sleeve plate is fixedly connected to the top of the compression spring. A rotating rod is fixedly connected to the inner wall of the roller, and the rotating rod is rotatably connected to the housing via a ball bearing. A motor is fixedly connected to one end of the rotating rod, and the motor is fixedly connected to the housing. A square rod is inserted into the top of the horizontal plate, and the top of the square rod is fixedly connected to the housing. The through-face of the square rod and the horizontal plate is clearance-fitted.
[0008] Preferably, the outer wall of the conical annular groove is fixedly fitted with an anti-slip sleeve.
[0009] Preferably, the top end of the sleeve plate is connected to an adjustment assembly, the adjustment assembly including: a threaded rod, a portion of which penetrates the sleeve plate, the outer wall of which is clearance-fitted with the penetration surface of the sleeve plate, the top end of which is fixedly connected to the housing, and a knob threadedly connected to the outer wall of which abuts against the sleeve plate.
[0010] Preferably, the outer wall of the upright is provided with graduations.
[0011] Preferably, a U-shaped rod is fixedly connected to the front surface of the U-shaped plate, and a silicone sleeve is fixedly fitted to the outer wall of the U-shaped rod.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] (1) This utility model utilizes the cooperation between the box body, through groove, material strip, electric push rod, bracket, cutter and guiding assembly. The user first passes one side of multiple material strips with the same or different outer diameters through the through groove into the box body, and places each material strip in a separate conical annular groove. Then, the bottom end of the abutment wheel is pressed against the material strip inside the conical annular groove. At this time, the motor and electric push rod are started. The motor operation can make the rotating rod and the circular roller rotate at a uniform speed, thereby transmitting the material strip at a uniform speed. The operation of the electric push rod can make the cutter perform intermittent up and down reciprocating motion, thereby performing quantitative cutting of the material strip in the path. During this process, since the conical annular groove and the abutment wheel can properly press and transmit material strips with different outer diameters, material strips with different outer diameters can be used in the same batch. This feature expands its application range and improves its practical performance.
[0014] (2) Through the cooperation between the box, through groove, material strip, electric push rod, bracket, cutter, material guide assembly and adjustment assembly, the user can apply force to rotate the knob to adjust the height position of the knob on the threaded rod, and then adjust the force applied by the sleeve plate to the compression spring, thereby controlling the clamping force of the abutment wheel on the material strip below. This allows multiple material strips with different outer diameters to be under the same clamping force, which is conducive to the uniform and equidistant stable transmission of multiple material strips, and facilitates high-quality cutting operations.

Detailed Implementation
[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments of the present invention include, but are not limited to, the following embodiments.
[0021] Example 1: As Figures 1-4 As shown, this utility model provides an adjustable polymer material pelletizer, comprising: a housing 1, with detachable movable doors at both the front and rear ends of the housing 1, allowing easy access to the internal structural components of the housing 1 by removing the movable doors; a discharge port at the bottom of the housing 1 for easy discharge of the cut material; through grooves 2 on both the front and rear sides of the housing 1, with multiple material strips 3 inside the through grooves 2; and an electric push rod 4 fixedly connected to the rear top of the interior of the housing 1, with the output shaft of the electric push rod 4 fixedly connected to a cutter 6; and the outer wall of the electric push rod 4 fixedly sleeved with... A bracket 5 is provided, with its top end fixedly connected to the housing 1. A cutter 6 is fixedly connected to the bottom end of the electric push rod 4. The models of the electric push rod 4 and the motor 21 are not limited, as long as they meet the usage requirements. The power cords of the electric push rod 4 and the motor 21 are connected to an external power supply device to provide the necessary power for their operation. A material guide assembly is provided on the outer side of the material strip 3. The material guide assembly includes a circular roller 7, which is located below the material strip 3. The outer wall of the circular roller 7 is evenly provided with multiple conical annular grooves 8. The inner wall of the conical annular grooves 8 abuts against the material strip 3. A stop roller 9 is provided at the top, and the bottom end of the stop roller 9 abuts against the material strip 3. A U-shaped plate 10 is provided above the stop roller 9. The U-shaped plate 10 is rotatably connected to the stop roller 9 through a rotating shaft 11. The outer wall of the rotating shaft 11 is fixedly connected to the stop roller 9. The rotating shaft 11 is rotatably connected to the U-shaped plate 10 through a ball bearing. A vertical rod 12 is fixedly connected to the top of the U-shaped plate 10. A horizontal plate 15 is fixedly sleeved on the outer wall of the vertical rod 12. A compression spring 14 is fixedly connected to the top of the horizontal plate 15. The elastic coefficient of the compression spring 14 is 2-15 N / cm. A sleeve plate 13 is fixedly connected to the top of the compression spring 14. The roller 7 is fitted with a clearance fit to the upright 12. A clearance fit refers to a fit with a gap (including a minimum gap of zero). A rotating rod 20 is fixedly connected to the inner wall of the roller 7. The rotating rod 20 is rotatably connected to the housing 1 through a ball bearing. A motor 21 is fixedly connected to one end of the rotating rod 20. The output shaft of the motor 21 is fixedly connected to the rotating rod 20. The motor 21 is fixedly connected to the housing 1. The housing of the motor 21 is fixedly connected to the housing 1. A square rod 22 is inserted into the top of the horizontal plate 15. The top of the square rod 22 is fixedly connected to the housing 1. The square rod 22 and the through surface of the horizontal plate 15 are fitted with a clearance fit.
[0022] Example 2: The outer wall of the conical annular groove 8 is fixedly fitted with an anti-slip sleeve 16. The anti-slip sleeve 16 is made of rubber and has a certain degree of flexibility, which can increase the frictional resistance of the outer wall of the conical annular groove 8 and facilitate the stable transmission of the material strip 3.
[0023] Example 3: An adjustment assembly is connected to the top of the sleeve plate 13. The adjustment assembly includes a threaded rod 17, a part of which passes through the sleeve plate 13. The outer wall of the threaded rod 17 is clearance-fitted with the through surface of the sleeve plate 13. The top of the threaded rod 17 is fixedly connected to the housing 1. A knob 18 is threadedly connected to the outer wall of the threaded rod 17. The knob 18 is pressed against the sleeve plate 13. The user can apply force to rotate the knob 18 to adjust the height position of the knob 18 on the threaded rod 17, thereby adjusting the force applied by the sleeve plate 13 to the compression spring 14, thereby controlling the pressing force of the abutment wheel 9 on the lower material strip 3.
[0024] Example 4: The outer wall of the upright 12 is provided with a scale 19. The scale 19 makes it easy for the user to judge the strength of the rebound force applied by the compression spring 14 to the horizontal plate 15, and to control the strength of the pressing force applied by the abutment wheel 9 to the material strip 3.
[0025] Example 5: A U-shaped rod is fixed to the front surface of the U-shaped plate 10, and a silicone sleeve is fixedly fitted to the outer wall of the U-shaped rod. The U-shaped rod is designed to facilitate the application of force when the abutment wheel 9 is moved away from the round roller 7. The silicone sleeve is made of silicone material, which makes it easy for the user to apply force to the U-shaped rod stably.
[0026] In use, the user first applies upward force to the abutment roller 9, causing it to move away from the circular roller 7. Then, multiple strips 3 with the same or different outer diameters are passed through the through groove 2 through the housing 1, with each strip 3 placed inside a separate conical annular groove 8. The upward force on the abutment roller 9 is then released, and the compression spring 14 rebounds, causing the bottom of the abutment roller 9 to press against the strip 3 inside the conical annular groove 8. During this process, the knob 18 can be rotated to adjust its height on the threaded rod 17, thereby adjusting the force applied by the sleeve 13 to the compression spring 14, thus controlling the pressing force of the abutment roller 9 against the strip 3 below. This method allows multiple strips 3 of different outer diameters to be subjected to the same clamping force. When the motor 21 and electric push rod 4 are started, the motor 21 causes the rotating rod 20 and the circular roller 7 to rotate at a uniform speed, thus transmitting the strips 3 at a uniform speed. The electric push rod 4 causes the cutter 6 to perform intermittent up-and-down reciprocating motion, thereby quantitatively cutting the strips 3 along its path. During this process, because the conical annular groove 8 and the abutment wheel 9 can properly clamp and transmit strips 3 of different outer diameters, strips 3 of different outer diameters can be used in the same batch. This feature expands its applicability and improves its practical performance. The above embodiment is only one of the preferred embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any modifications or refinements made to the main design concept and spirit of this utility model that are not substantial in nature, but which still solve the same technical problem as this utility model, should be included within the scope of protection of this utility model.
