Description

Technical Field

[0001] This utility model relates to the field of resin processing technology, specifically to a pelletizer for processing anti-clogging polyurethane resin. Background Technology

[0002] Resins are divided into natural resins and synthetic resins. Natural resins refer to amorphous organic substances obtained from the secretions of plants and animals in nature, such as rosin, amber, and shellac. Synthetic resins refer to resin products obtained by chemical synthesis of simple organic substances or by chemical reaction of certain natural products, such as phenolic resin and polyvinyl chloride resin. Among them, synthetic resins are the main components of plastics.

[0003] According to a publicly disclosed pelletizer for resin granulation (Announcement No.: CN219855458U), the above application adds blades, membrane holes and pressure plates to enable resin raw materials to be extruded through the bottom of the barrel for pelletizing, which increases the convenience of pelletizing, avoids the increase of labor intensity for workers by traditional pelletizing methods, and effectively improves the efficiency of material cutting.

[0004] However, there are some drawbacks in its use. Because the membrane pores have a certain depth, the pressure plate cannot apply pressure to the resin inside the membrane pores, resulting in residual resin inside the membrane pores after processing. After solidification, this causes blockage of the membrane pores. Utility Model Content

[0005] The purpose of this invention is to provide a pelletizer for processing polyurethane resin that prevents clogging, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pelletizer for processing anti-clogging polyurethane resin, comprising a barrel body, wherein multiple sets of arrayed support legs are fixedly connected to the side wall of the barrel body, multiple sets of arrayed membrane holes are opened on the bottom surface of the barrel body, a pressing component is provided on the surface of the support legs, the pressing component includes a support plate, the support plate is fixedly connected to the surface of the support legs, a cylinder is fixedly connected to the top of the support plate, the output end of the cylinder passes through and is slidably connected to the bottom surface of the support plate, a pressure plate is fixedly connected to the output end of the cylinder, and multiple sets of arrayed unblocking cones are fixedly connected to the bottom surface of the pressure plate.

[0007] Preferably, a cutting assembly is fixedly connected to the bottom surface of the barrel. The cutting assembly includes a discharge hopper, which is rotatably connected to the bottom surface of the barrel. A support frame is fixedly connected to the inner wall of the discharge hopper. A boss is fixedly connected to the surface of the support frame. A through groove is opened on the side wall of the boss. A sliding plate is slidably connected inside the through groove. A collar is fixedly connected to the end of the sliding plate. The collar is sleeved on the outer wall of the boss. Multiple sets of neatly arranged blades are fixedly connected to the outer surface of the collar.

[0008] Preferably, a toothed ring is fixedly connected to the outer wall of the discharge hopper, a motor is fixedly connected to the side wall of the barrel, and a gear is fixedly connected to the output shaft of the motor, with the toothed ring meshing with the gear.

[0009] Preferably, the slide plate is elastically connected to the inner wall of the through groove by a support spring.

[0010] Preferably, the upper inner wall of the membrane pore is inclined.

[0011] Preferably, the position and diameter of the unblocking cone are adapted to the membrane pores.

[0012] Compared with the prior art, this utility model provides a pelletizer for processing polyurethane resin that prevents clogging, and has the following beneficial effects:

[0013] 1. This anti-clogging polyurethane resin pelletizer, by setting membrane holes with inclined inner walls, enables the resin to flow more smoothly under gravity. At the same time, during the pressing process of the pressure plate, the unblocking cone can be inserted into the membrane hole to effectively unblock the residual resin, further ensuring the smooth flow of the membrane hole, guaranteeing the continuity and stability of the pelletizing process, and improving production efficiency.

[0014] 2. This anti-clogging polyurethane resin pelletizer uses a support spring to provide upward force to the blade, ensuring that the blade always remains in contact with the bottom surface of the barrel. This prevents uneven cutting caused by wear and tear between the blade and the bottom surface of the barrel, thus guaranteeing the stability of the cutting effect and quality.

[0017] like Figures 1-4As shown, this utility model provides a technical solution: a pelletizer for processing anti-clogging polyurethane resin, including a barrel 1. Multiple sets of arrayed support legs 11 are fixedly connected to the side wall of the barrel 1. The barrel 1 is used to hold the polyurethane resin raw material to be processed. The multiple sets of support legs 11 support the barrel 1, raising it a certain distance off the ground to facilitate the falling of the pelletized resin particles, and also provide an installation position for the pressing component 3. Multiple sets of arrayed membrane holes 2 are opened on the bottom surface of the barrel 1. The upper inner wall of the membrane holes 2 is inclined. The multiple sets of membrane holes 2 allow the resin to be extruded evenly, and the inclined inner wall allows the resin to flow downwards more easily along the inner wall of the membrane holes 2 under gravity, reducing the adhesion and retention of resin on the membrane hole 2 wall, thereby reducing the possibility of resin residue.

[0018] A pressing assembly 3 is provided on the surface of the support leg 11. The pressing assembly 3 includes a support plate 31, which is fixedly connected to the surface of the support leg 11. A cylinder 32 is fixedly connected to the top of the support plate 31. The output end of the cylinder 32 passes through and is slidably connected to the bottom surface of the support plate 31. A pressure plate 33 is fixedly connected to the output end of the cylinder 32. Multiple arrays of unblocking cones 34 are fixedly connected to the bottom surface of the pressure plate 33. The unblocking cones 34 are adapted to the position and diameter of the membrane holes 2. The cylinder 32 drives the pressure plate 33 to move downward through the extension and retraction of the output end, enters the interior of the barrel 1, and applies pressure to the resin raw material in the barrel 1, causing it to be squeezed out from the membrane holes 2. At the same time, the unblocking cones 34 on the bottom surface can be inserted into the interior of the membrane holes 2 during the pressing process of the pressure plate 33 to unblock the resin remaining in the membrane holes 2 and prevent the membrane holes 2 from being blocked. At the same time, a gap is left between the unblocking cones 34 and the inner wall of the membrane holes 2 to facilitate the passage of the remaining resin.

[0019] A cutting assembly 4 is fixedly connected to the bottom surface of the barrel 1. The cutting assembly 4 includes a discharge hopper 41, which is rotatably connected to the bottom surface of the barrel 1. A support frame 42 is fixedly connected to the inner wall of the discharge hopper 41. A boss 43 is fixedly connected to the surface of the support frame 42. A through groove 44 is opened on the side wall of the boss 43. A sliding plate 45 is slidably connected inside the through groove 44. The sliding plate 45 is elastically connected to the inner wall of the through groove 44 by a support spring 46. A collar 47 is fixedly connected to the end of the sliding plate 45. The discharge hopper 41 rotates, causing the support frame 42 and the boss 43 to rotate synchronously. The sliding plate 45 inside the groove 44 positions the collar 47, allowing it to move vertically but not circumferentially. This ensures the collar 47 rotates synchronously with the discharge hopper 41. The collar 47 is fitted onto the outer wall of the boss 43. Multiple sets of neatly arranged blades 48 are fixedly connected to the outer surface of the collar 47. A support spring 46 provides upward force to the blades 48, ensuring they remain in contact with the bottom surface of the barrel 1. This guarantees stable cutting of the resin extruded from the membrane orifice 2 during rotation, ensuring cutting effect and quality. A toothed ring 49 is fixedly connected to the outer wall of the discharge hopper 41, and a motor 410 is fixedly connected to the side wall of the barrel 1. A gear 411 is fixedly connected to the output shaft of the motor 410, and the toothed ring 49 meshes with the gear 411. The motor 410 drives the gear 411 through its output shaft, causing the meshing toothed ring 49 to rotate the discharge hopper 41, which in turn causes the blades 48 to rotate synchronously, cutting the extruded resin into granules.

[0020] In this invention, when in use, the polyurethane resin raw material to be processed is first placed into the barrel 1, where it awaits extrusion and pelletizing.

[0021] Then, the cylinder 32 of the pressing component 3 is activated. The output end of the cylinder 32 extends, driving the pressure plate 33 to move downward and enter the barrel 1. Pressure is applied to the polyurethane resin raw material inside the barrel 1, causing the resin raw material to be extruded from the membrane hole 2 under pressure. Since the upper inner wall of the membrane hole 2 is inclined, the resin raw material can be extruded relatively smoothly.

[0022] As the polyurethane resin raw material gradually decreases, and as the pressure plate 33 descends, the unblocking cone 34 on the bottom surface of the pressure plate 33 will be inserted into the membrane hole 2 to unblock the membrane hole 2 and ensure that the membrane hole 2 is unobstructed.

[0023] Simultaneously with the extrusion of the resin raw material, the motor 410 is started. The output shaft of the motor 410 drives the gear 411 to rotate, and the gear 411 meshes with the gear ring 49 on the outer wall of the discharge hopper 41, thereby driving the discharge hopper 41 to rotate. When the discharge hopper 41 rotates, its internal support frame 42 and boss 43 rotate synchronously. Since the collar 47 at the end of the slide plate 45 is sleeved on the outer wall of the boss 43 and the slide plate 45 is restricted by the through groove 44 and cannot move circumferentially, the collar 47 will rotate with the discharge hopper 41. At the same time, the blade 48 fixed on the collar 47 also rotates. Under the action of the support spring 46, the blade 48 always remains in contact with the bottom surface of the barrel 1, so that the blade 48 can stably cut the resin extruded from the membrane hole 2 during rotation, cutting the resin into granules. The granulated resin particles fall from below the discharge hopper 41.

[0024] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
