Description

A mixing device for processing plastic foam Technical Field

[0001] This utility model belongs to the field of plastic foam processing technology, and specifically relates to a stirring device for plastic foam processing. Background Technology

[0002] Plastic foam, also known as foamed plastic, is a polymer material formed by dispersing a large number of gas micropores in solid plastic. It has the advantages of being lightweight, heat-insulating, sound-absorbing, shock-absorbing, and corrosion-resistant, and is therefore widely used in many fields. In the raw material mixing stage, plastic raw materials, foaming agents, additives, etc. need to be stirred to ensure that the various components are fully mixed and uniform. A stirring device is required during stirring.

[0003] In existing technologies, after the mixed raw materials are discharged, they are discharged through a discharge pipe. However, since plastic raw materials are granular, they tend to accumulate at the discharge point after being mixed with additives (some additives increase the viscosity of plastic raw materials and reduce their fluidity, such as plasticizers), resulting in slow discharge and affecting the discharge operation. Therefore, a technical measure is proposed to solve the problem that existing technologies lack a mechanism for quickly discharging the mixed raw materials, and that the granular nature of plastic raw materials makes them prone to accumulating at the discharge point after being mixed with additives, causing slow discharge and affecting the discharge operation. Summary of the Invention

[0004] (1) Technical problems to be solved

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a stirring device for plastic foam processing, which aims to solve the problem that the existing technology lacks a mechanism for quickly discharging the mixed raw materials. Since the plastic raw materials are granular, they tend to accumulate at the discharge point after mixing with additives, resulting in slow discharge and affecting the discharge operation.

[0006] (2) Technical solution

[0007] To address the aforementioned technical problems, this utility model provides a mixing device for processing plastic foam, comprising a base plate and a tank. A first support frame and a second support frame are mounted on the upper surface of the base plate, and the first and second support frames are symmetrically installed. Two sets of symmetrically distributed rotating rods are mounted on the side of the tank, and the rotating rods are rotatably connected to the first support frame. The lower part of the tank contacts the second support frame, and the lower part of the tank is horizontally positioned. A lifting component is installed in the middle of the upper surface of the base plate. Thanks to the lifting component, the tank can be easily lifted and tilted at a certain angle, thereby enabling the rapid discharge of the mixed raw materials, increasing the discharge speed, ensuring smooth discharge operations, and improving work efficiency. Simultaneously, the two support frames facilitate support of the tank, improving its stability, and limiting the upward lifting height of the tank to prevent excessive tipping.

[0008] Furthermore, a guide plate is installed on the side of the first support frame, the guide plate is inclined, and a collection box is provided at the lower part of the guide plate.

[0009] Furthermore, a feed pipe is installed through the middle of the upper surface of the tank, and a pipe cover is movably installed on the feed pipe.

[0010] Furthermore, a tank door is provided on the side of the tank facing the first support frame, and a motor is installed in the middle of the side of the tank away from the first support frame.

[0011] Furthermore, the motor is connected to a round rod, which is rotatably connected to the tank body, and multiple sets of evenly distributed stirring plates are installed on the outside of the round rod.

[0012] Furthermore, the lifting assembly includes a hydraulic cylinder, which is fixedly installed at the middle position of the upper surface of the base plate. A collar is fixedly sleeved on the upper end of the hydraulic cylinder, and two sets of side plates are symmetrically installed on the side of the collar. A vertical rod is installed on the upper surface of the side plate, and a circular ring is installed at the upper end of the vertical rod.

[0013] Furthermore, the annulus is fitted with connecting rods, and there are two sets of connecting rods. A top rod is installed at one end of each set of connecting rods that is close to each other, and the upper part of the top rod contacts the lower part of the tank.

[0014] (3) Beneficial effects

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention, through the arrangement of a motor, a round rod, and a stirring plate, facilitates the uniform mixing of plastic raw materials, foaming agents, and additives. The motor starts and drives the round rod and stirring plate to rotate, thereby mixing the plastic raw materials, foaming agents, and additives evenly.

[0017] The second support frame facilitates support of the tank, improves its stability, and limits the upward lifting height of the tank to prevent it from tipping over.

[0018] The guide plate and collection box facilitate the guidance and collection of the falling mixed raw materials. The mixed raw materials fall into the guide plate and then into the collection box under the guidance of the guide plate, thus completing the collection.

[0019] The lifting assembly allows the tank to be lifted and tilted at a certain angle, enabling the tank to quickly discharge the mixed raw materials, increasing the discharge speed, ensuring smooth discharge operations, and improving work efficiency.

[0027] 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.

[0028] This specific embodiment is a mixing device for processing plastic foam. Its structural schematic diagram is shown in Figures 1, 2, 3, and 4. It includes a base plate 9 and a tank body 1. A first support frame 4 and a second support frame 6 are mounted on the upper surface of the base plate 9, and the first support frame 4 and the second support frame 6 are symmetrically installed. Two sets of symmetrically distributed rotating rods 3 are mounted on the side of the tank body 1, and the rotating rods 3 are rotatably connected to the first support frame 4. The lower part of the tank body 1 contacts the second support frame 6, and the lower part of the tank body 1 is horizontally positioned. A lifting assembly 2 is installed in the middle of the upper surface of the base plate 9. A guide plate 10 is installed on the side of the first support frame 4, and the guide plate 10 is inclined. A collection box 11 is provided at the lower part of the guide plate 10. A feed pipe 7 is installed through the middle of the upper surface of the tank body 1, and a pipe cover 8 is movably installed on the feed pipe 7. A tank door 5 is provided on the side of the tank body 1 facing the first support frame 4, and a door 5 is provided on the middle of the side of the tank body 1 away from the first support frame 4. The device is equipped with a motor 12, which is connected to a round rod 13. The round rod 13 is rotatably connected to the tank body 1. Multiple sets of evenly distributed stirring plates 14 are installed on the outside of the round rod 13. When mixing raw materials, the pipe cover 8 is opened, and then plastic raw materials, foaming agents, and additives are injected in proportion through the feed pipe 7. Then, the motor 12 is started to drive the round rod 13 to rotate. The rotation of the round rod 13 drives the stirring plates 14 to rotate. The stirring plates 14 rotate to mix the plastic raw materials, foaming agents, and additives. After mixing is completed, the tank door 5 is opened, and then the lifting assembly 2 is started to lift the tank body 1. The tank body 1 rotates upward along the rotating rod 3. Then, the mixed raw materials fall into the guide plate 10 and fall into the collection box 11 under the action of the guide plate 10 to complete the collection. The setting of the motor 12, round rod 13, and stirring plates 14 facilitates the uniform mixing of plastic raw materials, foaming agents, and additives.

[0029] Referring to Figures 1, 2, 3, and 5, the lifting assembly 2 includes a hydraulic cylinder 201, which is fixedly installed at the middle position of the upper surface of the base plate 9. A collar 202 is fixedly sleeved on the upper end of the hydraulic cylinder 201. Two sets of side plates 203 are symmetrically installed on the side of the collar 202. A vertical rod 204 is installed on the upper surface of the side plate 203. A ring 205 is installed on the upper end of the vertical rod 204. A connecting rod 207 is sleeved on the ring 205. There are two sets of connecting rods 207. A push rod 206 is installed at the end of the two sets of connecting rods 207 that are close to each other. The upper part contacts the lower part of the tank body 1. The hydraulic cylinder 201 is activated. The activation of the hydraulic cylinder 201 drives the collar 202 to move upward. The upward movement of the collar 202 drives the side plate 203 to move upward. The upward movement of the side plate 203 drives the vertical rod 204 to move upward. The upward movement of the vertical rod 204 drives the ring 205 to move upward. The upward movement of the ring 205 drives the connecting rod 207 to move upward. The upward movement of the connecting rod 207 drives the top rod 206 to move upward. The upward movement of the top rod 206 lifts the tank body 1, thereby causing the tank body 1 to tilt at a certain angle.

[0030] Working principle: When mixing raw materials, the pipe cover 8 is opened, and then plastic raw materials, foaming agent, and additives are injected in proportion through the feed pipe 7. Then, the motor 12 is started to drive the round rod 13 to rotate. The rotation of the round rod 13 drives the stirring plate 14 to rotate. The rotation of the stirring plate 14 mixes the plastic raw materials, foaming agent, and additives. After mixing, the tank door 5 is opened, and then the lifting assembly 2 is started to lift the tank 1. The tank 1 rotates upward along the rotating rod 3. Then, the mixed raw materials fall into the guide plate 10 and fall into the collection box 11 under the action of the guide plate 10, and are collected. The setting of the motor 12, round rod 13, and stirring plate 14 facilitates the uniform mixing of plastic raw materials, foaming agent, and additives. The setting of the second support frame 6 facilitates the support of the tank 1, improves the stability of the tank 1, and limits the upward lifting height of the tank 1 to prevent it from tipping over. The setting of the guide plate 10 and the collection box 11 facilitates the guidance and collection of the falling mixed raw materials.

[0031] The lifting assembly 2 works as follows: The hydraulic cylinder 201 is activated, causing the collar 202 to move upward. This upward movement of the collar 202 then moves the side plate 203 upward, which in turn moves the vertical rod 204 upward. The upward movement of the vertical rod 204 then moves the ring 205 upward, which in turn moves the connecting rod 207 upward. The upward movement of the connecting rod 207 then moves the top rod 206 upward, lifting the tank 1 and causing it to tilt at a certain angle. The lifting assembly 2 facilitates lifting and tilting the tank 1 at a specific angle, thus enabling the rapid discharge of the mixed raw materials from the tank 1. This increases the discharge speed, ensures smooth discharge operations, and improves work efficiency.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
