Description

Technical Field

[0001] This utility model relates to the field of recycling device technology, specifically a material recycling device for extruders used in the production of two-color rubber and plastic sheets. Background Technology

[0002] Two-color rubber and plastic sheets are usually made of two different rubber and plastic materials or different colors of the same material through a special process. They have excellent physical properties, chemical stability and processing performance. They are widely used in construction, automobiles, electronics, home appliances and other fields as materials for heat insulation, sound insulation, shock absorption and moisture protection. The production process of two-color rubber and plastic sheets cannot be separated from a specific extruder.

[0003] For example, the patent with announcement number CN2765764Y (a two-color plastic extruder) includes an electric device and two feeding devices. Each feeding device has a discharge port at its end. A mixing connector is provided between the two discharge ports. The inlet of the mixing connector is connected to the discharge port. The two discharge ports are adjacent to each other. The mixing connector has a mixing chamber. The outer surface of the mixing chamber is provided with an electric heating coil. The mixing chamber has two material channels. The inlets of the two material channels are respectively connected to the discharge ports of the two feeding devices. The tails of the two material channels are connected to form a mixing outlet. The tail of the mixing outlet is provided with a deformation outlet mold.

[0004] While the aforementioned existing technologies facilitate two-color extrusion, during the extrusion molding process, due to factors such as mismatched mold design, extrusion parameters, or differences in material properties, the material may be subjected to uneven shearing or frictional forces, resulting in a continuous waste strip along the side or surface of the product. Traditionally, the handling of this continuous waste strip relies mainly on manual collection, which is inefficient, increases the labor intensity of workers, and has poor practicality. Therefore, the market urgently needs to develop a waste recycling device for extruders used in the production of two-color rubber and plastic sheets to help solve the existing problems.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figure 1-4 This utility model provides an embodiment of a material recycling device for an extruder used in the production of two-color rubber and plastic sheets. The device includes a traction mechanism 2, with a material trough 1 on one side. The traction mechanism 2 includes a vertical plate 201, a guide roller 202, a drive roller 203, a first side plate 204, a lower pressing assembly 205, a second side plate 206, and an upper pressing assembly 207. Two vertical plates 201, two side plates 204, and two side plates 206 are provided. The vertical plate 201 is fixedly connected to the material trough 1. The guide roller 202 and the drive roller 203 are symmetrically rotated and installed above and below the two vertical plates 201, respectively. A drive motor for the drive roller 203 is provided at the front end of the vertical plate 201. The two first side plates 204 and two second side plates 206 are fixedly installed below and above one side of the two vertical plates 201, respectively. The lower pressing assembly 205 is located between the two first side plates 204, and the upper pressing assembly 207 is located between the two second side plates 206.

[0024] In use, the material trough 1 of the recycling device is set below the discharge port of the extruder used for the production of two-color rubber and plastic sheets, so that the recycled material belt during the extrusion process of the two-color rubber and plastic sheets falls into the material trough 1. Then, the recycled material belt is pulled into the traction mechanism 2, so that the recycled material belt is pulled upward between the guide roller 202 and the lower pressing assembly 205, and then pulled out between the drive roller 203 and the upper pressing assembly 207, so that the recycled material belt is led out to the feed port of an extruder, thereby realizing the recycling of the recycled material belt.

[0025] Furthermore, the traction mechanism and the material trough work together to facilitate the collection and traction of the recycled material belt without manual intervention, thereby improving recycling efficiency and reducing labor intensity. The design of the guide roller, drive roller, and upper and lower clamping components in the traction mechanism ensures stable transmission of the recycled material belt during the recycling process, preventing the recycled material belt from accumulating or falling off, further enhancing the continuity and stability of recycling. In addition, by directly introducing the recycled material belt into the feed inlet of an extruder, the recycling of materials is realized, reducing material waste, lowering production costs, and increasing practicality.

[0026] Please see Figure 3 A top plate 10 is fixedly installed above each of the two upright plates 201, and an output roller 11 is rotatably installed between the two top plates 10. Limiting rings are symmetrically arranged at both ends of the outer side of the output roller 11.

[0027] The output roller 11 is designed to facilitate the traction and output of the return belt. At the same time, the symmetrically arranged limiting rings at both ends of the outer side of the output roller 11 facilitate the stable output of the return belt and increase its practicality.

[0028] Please see Figure 3 and Figure 4 The upper clamping assembly 207 and the lower clamping assembly 205 have the same internal structure. The lower clamping assembly 205 includes a mounting plate 2051, a roller frame 2052, a pressure roller 2053, an electric cylinder 2054, and a guide rod 2055. The two ends of the mounting plate 2051 are fixedly connected to the two side plates 204 respectively. The roller frame 2052 is set on one side of the mounting plate 2051. The pressure roller 2053 is rotatably installed inside the roller frame 2052. The electric cylinder 2054 is fixedly installed on the other side of the mounting plate 2051. The push rod end of the electric cylinder 2054 slides through the mounting plate 2051 and is fixedly connected to the roller frame 2052.

[0029] The upper clamping assembly 207 and the lower clamping assembly 205 have the same internal structure. The push rod end of the electric cylinder 2054 is fixedly connected to the roller frame 2052, which can adjust the pressure of the pressure roller 2053 to ensure that the return belt is always in a clamped state during the traction process, and avoid slippage or falling off.

[0030] Please see Figure 4 There are two guide rods 2055, which are respectively located at the front end and rear end of the electric cylinder 2054, and one end of the guide rod 2055 slides through the mounting plate 2051 and is fixedly connected to the roller frame 2052.

[0031] The guide rod 2055 further enhances the stability of the translation adjustment of the pressure roller 2053 and prevents the pressure roller 2053 from shifting during the pressure adjustment process.

[0032] Please see Figure 2 Multiple lower material rollers 4 are rotatably installed inside the material trough 1. Multiple upper material rollers 5 are rotatably installed inside the material trough 1 along the upper part of the lower material rollers 4. A bottom cylinder 3 is fixedly installed below the material trough 1. A blower 9 is fixedly installed inside the bottom cylinder 3. A gas distributor 6 is fixedly installed inside the material trough 1 along the lower part of the lower material rollers 4. The lower end of the gas distributor 6 extends into the interior of the bottom cylinder 3. Long strip plates 8 are symmetrically fixedly installed on both sides of the upper part of the material trough 1. Air jet slots 801 are provided inside the long strip plates 8. An air conveying pipe 7 is fixedly installed below the long strip plates 8 and is connected to the air jet slots 801. The lower end of the air conveying pipe 7 extends into the interior of the bottom cylinder 3. When the return belt passes through the material trough 1, it passes between the lower material rollers 4 and the upper material rollers 5.

[0033] The feed trough 1 is equipped with a lower feed roller 4 and an upper feed roller 5, which can effectively guide the transmission path of the return material belt and prevent the return material belt from accumulating or getting stuck in the trough. The blower 9 installed in the bottom cylinder 3 distributes airflow into the feed trough 1 through the gas distributor 6 and the air supply pipe 7, which can air cool the surface of the freshly extruded return material belt, prevent the return material belt from sticking or accumulating, and ensure its smooth transmission. This not only improves the recycling efficiency of the return material belt, but also reduces production interruptions caused by the blockage of the return material belt and improves the operational stability of the equipment.

[0034] Working principle: During the extrusion production of two-color rubber and plastic sheets, the recycled material belt falls from the extruder outlet into the material trough 1. The lower material roller 4 and upper material roller 5 in the material trough 1 guide the recycled material belt to be transported smoothly. At the same time, the fan 9 in the bottom cylinder 3 distributes the airflow evenly into the material trough 1 through the gas distributor 6 and the air supply pipe 7 to cool the surface of the freshly extruded recycled material belt, prevent adhesion or accumulation, and ensure its smooth transport. The recycled material belt is then pulled into the traction mechanism 2, and pulled upward by the clamping action between the guide roller 202 and the lower clamping component 205. After stable transport by the drive roller 203 and the upper clamping component 207, it is finally led out from the output roller 11 to the feed port of an extruder, realizing the recycling of the recycled material belt. This achieves the collection, traction, and recycling of the recycled material belt without manual intervention, improving recycling efficiency and increasing practicality.
