A modified plastics production equipment

Abstract

This utility model discloses a modified plastic production equipment, including a discharge box with a discharge port on one side and a pelletizing rack around the discharge port, on which a pelletizing mechanism is installed. A cold water tank is located below the discharge port, and a cooling mechanism is located on one side of the cold water tank. A baffle is installed on the pelletizing rack, and a scraper is mounted on the baffle. In this equipment, the pelletizing mechanism uses a cylinder to drive the pelletizing disc, which in turn drives the cutting wheel to pelletize the plastic strip at the discharge port. Simultaneously, the scraper on the baffle, with its side near the discharge port against the cutting wheel and angled, effectively cleans residual plastic from the cutting wheel, preventing it from affecting subsequent cutting. Furthermore, the cooling mechanism directly and evenly cools the plastic just exiting the discharge port, preventing deformation due to excessive temperature and ensuring that the plastic does not stick to the cutting wheel during cutting.

Description

Technical Field

[0001] This utility model relates to a modified plastics production equipment. Background Technology

[0002] Modified plastics refer to plastic products that have been modified from general-purpose plastics and engineering plastics through methods such as filling, blending, and reinforcement, thereby improving their properties such as flame retardancy, strength, impact resistance, and toughness. When these plastics need to be processed, modified plastic pelletizing equipment is required to pelletize them, thus facilitating subsequent processing.

[0003] Existing pelletizing equipment typically uses a cutter to cut plastic strips. When the cutter comes into contact with the plastic strip, friction generates instantaneous high temperatures, which may cause the modified plastic particles to have rough edges and melt easily, resulting in poor pelletizing effect. Furthermore, the plastic strip is at a high temperature before pelletizing and is prone to sticking to the outer surface of the cutter. Utility Model Content

[0004] The main objective of this invention is to provide a modified plastics production equipment to solve the aforementioned technical problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a modified plastic production equipment, including a discharge box, a discharge port on one side of the discharge box, a pelletizing rack on the outer periphery of the discharge port, and a pelletizing mechanism on the pelletizing rack; a cold water tank below the discharge port, and a cooling mechanism on one side of the cold water tank; a baffle on the pelletizing rack, and a scraper on the baffle.

[0006] Based on the above scheme and as a preferred embodiment: the pelletizing mechanism includes a pelletizing disc, a drive handle fixedly mounted on one side of the pelletizing disc, a connecting disc in the middle of the pelletizing disc, a connecting arm on the connecting disc, one end of the connecting arm being fixedly connected to the pelletizing disc, and a turntable on the other end, a first connecting shaft rotatably mounted on the turntable; a rotating shaft on the connecting disc, a cutting wheel at one end of the rotating shaft, a first connecting rod rotatably connected to the other end of the rotating shaft, a second connecting rod hinged to one end of the first connecting rod, a second connecting shaft rotatably mounted to the other end of the second connecting rod, and one end of both the first connecting shaft and the second connecting shaft being fixedly connected to the pelletizing frame.

[0007] Based on the above scheme and as a preferred embodiment of the above scheme: an arc-shaped groove is provided on the pelletizing disc, and a slider is provided at one end of the second connecting rod, the slider being slidably connected to the arc-shaped groove.

[0010] Based on the above scheme and as a preferred embodiment of the above scheme: the side of the scraper near the discharge port abuts against the cutting wheel, and the scraper is set at an angle.

[0011] The beneficial effects of this utility model are as follows: In this equipment, the pelletizing mechanism is set up so that the cylinder drives the pelletizing disc to move, which in turn drives the cutting wheel to pelletize the plastic strip at the outlet; at the same time, the scraper on the baffle plate is in contact with the cutting wheel near the outlet and is set at an angle, which can better clean the residual plastic on the cutting wheel and prevent the residual plastic from affecting subsequent cutting; and through the setting of the cooling mechanism, the plastic that just comes out of the outlet can be cooled in a timely and uniform manner, avoiding deformation of the plastic due to excessive temperature, and also ensuring that the plastic does not stick to the cutting wheel during cutting.

[0013] Figure 2 This is an axonometric view of the present invention. Detailed Implementation

[0014] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. However, the specific implementation methods and embodiments described below are for illustrative purposes only and are not intended to limit the present invention.

[0015] See attached diagram. Figures 1 to 2 The modified plastic production equipment in this embodiment includes a discharge box 1, a discharge port 10 on one side of the discharge box 1, a pelletizing rack 2 on the outer periphery of the discharge port 10, and a pelletizing mechanism on the pelletizing rack 2; a cold water tank 4 is provided below the discharge port 10, and a cooling mechanism is provided on one side of the cold water tank 4; a baffle 7 is provided on the pelletizing rack 2, and a scraper 70 is provided on the baffle 7.

[0016] Furthermore, the pelletizing mechanism includes a pelletizing disc 3, a drive handle 37 fixedly mounted on one side of the pelletizing disc 3, a connecting disc 30 in the middle of the pelletizing disc 3, a connecting arm 31 on the connecting disc 30, one end of the connecting arm 31 being fixedly connected to the pelletizing disc 3, and a turntable 32 on the other end, with a first connecting shaft 320 rotatably mounted on the turntable 32; a rotating shaft 33 on the connecting disc 30, a cutting wheel 330 at one end of the rotating shaft 33, and a first connecting rod 34 rotatably connected to the other end of the rotating shaft 33, a second connecting rod 35 hinged to one end of the first connecting rod 34, and a second connecting shaft 36 rotatably mounted to the other end of the second connecting rod 35, with one end of the first connecting shaft 320 and the second connecting shaft 36 both being fixedly connected to the pelletizing frame 2.

[0017] Furthermore, an arc-shaped groove 300 is provided on the pelletizing disc 3, and a slider 301 is provided at one end of the second connecting rod 35, which is slidably connected to the arc-shaped groove 300.

[0018] Furthermore, a mounting bracket 6 is provided on one side of the pelletizing frame 2, and a cylinder 60 is hinged on the mounting bracket 6. The output end of the cylinder 60 is provided with a drive handle 37 hinged.

[0019] Furthermore, the cooling mechanism includes a water pump 5 connected to the cold water tank 4. The output end of the water pump 5 is provided with a water supply pipe 50, and the end of the water supply pipe 50 is provided with a spray head 51. The output end of the spray head 51 faces the discharge port 10. In one possible implementation, the water supply pipe 5 is fixed to the pelletizing frame 2 by a fixing buckle.

[0020] Furthermore, the side of the scraper 70 closest to the discharge port 10 abuts against the cutting wheel 330, and the scraper 70 is set at an angle.

[0021] Working principle: The plastic strip is discharged through the discharge port 10 of the discharge box 1; after discharge, the water pump 5 is started, and the water pump 5 delivers the water in the cold water tank 4 to the spray head 51 through the water pipe 50. The output end of the spray head 51 faces the discharge port 10, which can directly and evenly cool the plastic that just came out of the discharge port 10, and prevent the plastic from deforming due to excessive temperature.

[0022] After cooling the plastic strip, cylinder 60 is activated. Cylinder 60 drives the drive handle 37 to move, causing the pelletizing disc 3 to rotate under the coordinated action of turntable 32 and first connecting shaft 320. While the pelletizing disc 3 rotates, it drives the slider 301 to slide in the arc-shaped groove 300, thereby driving the second connecting rod to rotate around the second connecting shaft 36, which in turn drives the first connecting rod 34, the rotating shaft 33 and the cutting wheel 330 at one end of the rotating shaft 33 to rotate, thereby causing the pelletizing disc 3 and the cutting wheel 330 to move downward toward the discharge port as a whole, so as to pelletize the plastic strip.

[0023] After a pelletizing operation is completed, the cylinder 60 drives the pelletizing disc 3 to return to its original position. At the same time, the cutting wheel 330 also returns to its original position along with the pelletizing disc 3. As it returns to its original position, the scraper 70 on the baffle 7, which is close to the discharge port 10, abuts against the cutting wheel 330 and is set at an angle. This can better clean the residual plastic on the cutting wheel 330 and prevent the residual plastic from affecting subsequent cutting.

[0024] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
