Description

Technical Field

[0001] This utility model relates to the field of plastic pellet production technology, specifically to a raw material crusher for plastic pellet production. Background Technology

[0002] Plastic pellets are the basic raw material of the plastics industry. They are usually made from monomers refined from crude oil or natural gas through polymerization reactions, and then cut or granulated into small particles with a diameter of about 1-5 millimeters. They are widely used in the manufacture of various plastic products and are the core link in the plastics processing industry chain.

[0003] For example, patent application number 202322690263.7 published on the China Patent Network, entitled "A Raw Material Crusher for Plastic Particle Production," includes a casing, a feed inlet, and symmetrically arranged first crushing rollers. A collection box is fixedly connected to the middle of the casing. A clamping structure is provided inside the casing, including a handle rotatably connected to the casing. A double-ended lead screw is fixedly connected to one side of the handle, and threaded sleeves are symmetrically sleeved on both sides of the double-ended lead screw. A push plate is fixedly connected to the top of the threaded sleeves. Outer shells are fixedly connected to both sides of the casing, and a double-ended lead screw is rotatably connected inside the outer shell. A first sliding groove is opened on the top of the outer shell of the double-ended lead screw, and a second sliding groove is opened in front of the collection box. This invention solves the problem that plastic shavings are generated during plastic crushing, which accumulate on the guide plate over time, weakening the guiding effect of the guide plate and affecting the crushing effect of the nearest crushing roller. This necessitates manual cleaning of the interior, which is very troublesome.

[0004] However, the feeding method of existing crushers is relatively simple, mainly relying on the hopper for continuous feeding. The hopper has a fixed tilt angle, and the flat inner wall cannot effectively push the raw material to fall during the feeding process.

[0005] Therefore, it is necessary to redesign and modify the raw material crusher for plastic pellet production. Utility Model Content

[0006] To address the problems mentioned in the background art, the purpose of this utility model is to provide a raw material crusher for plastic pellet production, which has the advantage of improving feeding stability. It solves the problem that the feeding method of existing crushers is relatively simple, mainly relying on the hopper for continuous feeding, and the hopper has a fixed tilt angle, so the gentle inner wall cannot effectively push the raw material to fall during the feeding process.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a raw material crusher for producing plastic granules, comprising a machine body;

[0008] The top of the machine body is equipped with a hopper, and the front and back of the machine body are fixedly connected to brackets. A connecting block is fixedly connected to the left side of the brackets. The front and back of the hopper are fixedly connected to shafts. Both ends of the shafts pass through the connecting blocks and are movably connected to the connecting blocks. The hopper can rotate and swing using the shafts and change its tilt angle. The top of the machine body is equipped with a transmission structure that can control the rotation of the shafts.

[0009] In a preferred embodiment of this invention, the transmission structure includes an electric telescopic rod fixedly connected to the top of the machine body. A transmission block is fixedly connected to the output end of the electric telescopic rod. A sleeve plate is fixedly connected to the outer end of the shaft. The side of the sleeve plate away from the shaft extends to the outside of the transmission block. A push rod located inside the sleeve plate is fixedly connected to the outside of the transmission block. The push rod and the sleeve plate are slidably connected.

[0010] As a preferred embodiment of this utility model, a spring plate is fixedly connected to the right side of the hopper, and the side of the spring plate away from the hopper contacts the top of the machine body, and the spring plate is elastic.

[0011] As a preferred embodiment of this invention, a baffle is provided on the left side of the hopper, which can block the discharge end of the hopper.

[0012] As a preferred embodiment of this utility model, an extension plate is fixedly connected to the surface of the baffle, a force-bearing rod is fixedly connected to the side of the extension plate away from the baffle, a fork is fixedly connected to the inner side of the bracket, and the side of the fork away from the bracket is sleeved on the surface of the force-bearing rod.

[0013] As a preferred embodiment of this invention, the surface of the hopper is fixedly connected with guide rails located on both sides of the baffle, and the guide rails are slidably connected to the baffle.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model features an adjustable hopper angle to adapt to different material flow rates, avoiding material retention or blockage caused by a flat inner wall. By changing the tilt angle, the falling speed of the material is controlled, improving the uniformity of the crusher's feed and reducing the risk of equipment idling or overloading.

[0016] 2. The linear motion of this utility model is converted into rotary motion through push rod and sleeve plate, which has high transmission efficiency and compact structure. Moreover, the electric telescopic rod can be programmed to control the extension and retraction amount, realize fine adjustment of the hopper tilt angle, and adapt to the needs of precision production.

[0017] 3. This utility model uses the elastic deformation of the spring plate to always fit the machine body, preventing raw materials from leaking from the gap between the hopper and the machine body. At the same time, the elastic material absorbs the impact force when the hopper swings, reducing mechanical vibration and noise, and protecting the connection structure.

[0018] 4. This utility model limits the opening of the discharge port by using a baffle to prevent excessive discharge of raw materials from causing blockage of the crusher. The shielding design reduces the scattering of raw materials when they fall, thereby reducing dust pollution and material waste.

[0019] 5. This utility model achieves synchronous adjustment of the discharge port opening and tilt angle by driving the baffle to slide when the hopper swings, with the relative displacement of the fork and the force rod. This eliminates the need for a separate baffle drive, reducing energy consumption and control system complexity.

[0020] 6. This utility model restricts the sliding direction of the baffle by using a guide rail to prevent deviation or jamming, improves the stability of the operation, and the guide rail provides a smooth contact surface, reducing the sliding resistance of the baffle and extending the service life of the component.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figures 1 to 4 As shown, the present invention provides a raw material crusher for producing plastic pellets, comprising a machine body 1;

[0028] The top of the machine body 1 is equipped with a hopper 2. The front and back of the machine body 1 are fixedly connected with brackets 3. The left side of the brackets 3 is fixedly connected with a connecting block 4. The front and back of the hopper 2 are fixedly connected with shafts 5. Both ends of the shafts 5 pass through the connecting blocks 4 and are movably connected to the connecting blocks 4. The hopper 2 can rotate and swing and change its tilt angle by using the shafts 5. The top of the machine body 1 is equipped with a transmission structure 6, which can control the rotation of the shafts 5.

[0029] refer to Figure 2 The transmission structure 6 includes an electric telescopic rod 7 fixedly connected to the top of the body 1. The output end of the electric telescopic rod 7 is fixedly connected to a transmission block 8. The outer end of the shaft 5 is fixedly connected to a sleeve plate 9. The side of the sleeve plate 9 away from the shaft 5 extends to the outside of the transmission block 8. The outside of the transmission block 8 is fixedly connected to a push rod 10 located inside the sleeve plate 9. The push rod 10 and the sleeve plate 9 are slidably connected.

[0030] As a technical optimization of this utility model, linear motion is converted into rotational motion through push rod 10 and sleeve plate 9, which has high transmission efficiency and compact structure. Moreover, the electric telescopic rod 7 can be programmed to control the extension and retraction amount, realizing fine adjustment of the tilt angle of hopper 2, which is suitable for the needs of precision production.

[0031] refer to Figure 2 A spring plate 11 is fixedly connected to the right side of the hopper 2. The side of the spring plate 11 away from the hopper 2 contacts the top of the machine body 1. The spring plate 11 is elastic.

[0032] As a technical optimization of this utility model, the elastic plate 11 is always in contact with the machine body 1 through elastic deformation, which prevents the raw material from leaking from the gap between the hopper 2 and the machine body 1. At the same time, the elastic material absorbs the impact force when the hopper 2 swings, reduces mechanical vibration noise, and protects the connection structure.

[0033] refer to Figure 1 A baffle 12 is provided on the left side of the hopper 2, which can block the discharge end of the hopper 2.

[0034] As a technical optimization of this utility model, the baffle 12 limits the opening of the discharge port to prevent excessive discharge of raw materials from causing blockage of the crusher. The shielding design reduces the scattering of raw materials when they fall, thereby reducing dust pollution and material waste.

[0035] refer to Figure 1 An extension plate 13 is fixedly connected to the surface of the baffle 12. A force-bearing rod 14 is fixedly connected to the side of the extension plate 13 away from the baffle 12. A fork 15 is fixedly connected to the inner side of the bracket 3. The side of the fork 15 away from the bracket 3 is sleeved on the surface of the force-bearing rod 14.

[0036] As a technical optimization of this utility model, when the hopper 2 swings, the relative displacement of the fork 15 and the force rod 14 drives the baffle 12 to slide, thereby realizing the synchronous adjustment of the discharge port opening and tilt angle. There is no need to drive the baffle 12 separately, which reduces energy consumption and control system complexity.

[0037] refer to Figure 1 The surface of the hopper 2 is fixedly connected with guide rails 16 located on both sides of the baffle 12, and the guide rails 16 are slidably connected to the baffle 12.

[0038] As a technical optimization of this utility model, the guide rail 16 restricts the sliding direction of the baffle 12 to prevent deviation or jamming, improves the stability of the operation, and provides a smooth contact surface to reduce the sliding resistance of the baffle 12 and extend the service life of the component.

[0039] The working principle and usage process of this utility model are as follows: During operation, the electric telescopic rod 7 at the top of the machine body 1 is activated according to the preset program or sensor signal, and the output end pushes the transmission block 8. The push rod 10 on the outside of the transmission block 8 slides in the sleeve plate 9, converting linear motion into rotational torque. The shaft 5 drives the hopper 2 to rotate around the fulcrum of the connecting block 4, dynamically adjusting the tilt angle of the hopper 2. When the hopper 2 swings, the fixed fork 15 on the inner side of the bracket 3 and the force rod 14 of the extension plate 13 of the baffle 12 generate relative displacement, forcing the baffle 12 to slide along the guide rail 16. The baffle 12 moves synchronously with the angle of the hopper 2. For example, when the hopper 2 tilts downward, the baffle 12 moves backward to open the large discharge port, and moves forward to narrow the opening when swinging back, thereby achieving the effect of accurately controlling the flow rate of raw materials. The inner wall of the hopper 2 forms an asymmetrical force due to the periodic swing. The raw materials are accelerated to slide towards the discharge port by the combined action of gravity and inertia, avoiding the stagnation caused by the flat inner wall.

[0040] In summary, this raw material crusher for producing plastic granules features an adjustable hopper angle to adapt to different material flow characteristics, avoiding material retention or blockage caused by a flat inner wall. By changing the tilt angle, the crusher controls the material falling speed, improves the uniformity of feeding, and reduces the risk of equipment idling or overloading.
