Description

Technical Field

[0001] The present invention relates to the technical field of extruders, and particularly to an extruder with a waste treatment function. Background Art

[0002] As an important plastic processing equipment, extruders are widely used in the production of plastic pipes, plates, profiles, films and other products. During the extrusion molding process, waste materials will inevitably be generated, such as start-up materials, shutdown materials, unqualified products, etc. If these waste materials cannot be treated in a timely and effective manner, it will not only cause waste of resources, but also cause environmental pollution.

[0003] The existing waste treatment method of extruders mainly relies on manual collection. When manually collecting waste materials, it is also necessary to wait for the waste materials to cool and solidify before processing, which not only reduces the efficiency of waste material collection, but also increases the manual labor volume, resulting in an increase in the production cost of plastic processing.

[0004] According to the PVC edge banding extruder water cooling mechanism proposed in the publication number: CN222080020U, which includes a machine body, a water tank is fixedly connected to the right side of the front end of the machine body, a water injection pipe is fixedly connected to the top of the water tank, a water pump is fixedly installed at the rear of the machine body, the input end of the water pump is connected to the left side of the water tank through a connecting pipe, the output end of the water pump is fixedly connected to a condensation pipe, the other end of the condensation pipe is fixedly connected to a spray head, an extrusion pipe is fixedly connected to the top right side of the machine body, an installation frame is fixedly connected to the top of the machine body, and a cold air blower is fixedly installed inside the top of the installation frame. In this utility model, it is convenient to cool the PVC edge banding by water, improves the problem of low cooling efficiency caused by natural cooling, shortens the cooling time of the edge banding, improves the cooling efficiency, and thus reduces the phenomenon of delaying the work progress during the processing of the edge banding due to slow cooling, and is convenient for the recycling of condensed water.

[0005] According to the above introduction, during the production process of the extruder, it is necessary to cool the extruded plastic products. However, for the waste materials such as start-up materials and shutdown materials generated at the start or end of the production of the extruder, they still need to be manually collected and processed. However, the existing extruders do not have a waste treatment function and are generally collected manually. When manually collecting waste materials, it is also necessary to wait for the waste materials to cool and solidify before processing, which not only reduces the efficiency of waste material collection, but also increases the manual labor volume, resulting in an increase in the production cost of plastic processing. Therefore, in order to solve the above-mentioned problems, an extruder with a waste treatment function is proposed. Summary of the Invention

The designed waste treatment device can centrally treat the waste generated by the extruder main body, avoiding the waste being discarded everywhere. At the same time, in cooperation with the cooling mechanism, it can provide water cooling for the collected waste, enabling the waste to be quickly shaped and then falling onto the conveying rack. The conveying rack centrally collects the waste into the recycling box, avoiding waste of resources. The above settings not only replace the manual collection operation, thus adding a waste treatment function to the extruder main body, improving the efficiency of waste treatment and processing of the extruder main body, but also reducing the manual labor amount and lowering the plastic processing production cost, so as to solve the problems raised in the above background technology.

Detailed implementation manners

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] The present invention provides an extruder with a waste treatment function as shown in Figures 1 to 5 , which includes a support frame 1 and a main body 2 of the extruder installed on the support frame 1. A water cooling tank 3 is installed at one end of the support frame 1 far from the main body 2 of the extruder. A waste treatment device 4 for treating extrusion waste is provided between the water cooling tank 3 and the discharge port of the main body 2 of the extruder. And a cooling mechanism 5 is installed on the support frame 1 below the main body 2 of the extruder. One end of the cooling mechanism 5 is communicated with one side of the waste treatment device 4. A conveying frame 6 is provided at the discharge port position at the lower end of the waste treatment device 4. The conveying frame 6 is installed at the bottom of the support frame 1. A recycling box 7 is placed at one end of the conveying frame 6. The waste generated by the main body 2 of the extruder is discharged through the discharge port, processed by the waste treatment device 4, falls into the conveying frame 6, and is finally conveyed to the recycling box 7 for recycling, realizing automatic collection, treatment and recycling of waste, without manual intervention, improving production efficiency and reducing labor intensity.

[0030] The waste treatment device 4 includes an aggregate bin 41. The aggregate bin 41 is installed on the support frame 1 through fasteners and is located between the water cooling box 3 and the discharge port of the extruder body 2. One side of the aggregate bin 41 is communicated with one end of the cooling mechanism 5. A protective shell 42 is installed on one side of the lower end of the aggregate bin 41. An adjusting assembly 43 is arranged in the inner cavity of the protective shell 42. A connecting shaft 44 is fixedly connected in the inner cavity of the adjusting assembly 43. One end of the connecting shaft 44 is rotatably connected to the aggregate bin 41 through a bearing. A baffle 45 is fixedly connected to the connecting shaft 44 inside the aggregate bin 41. Two limiting strips 46 used in cooperation with the baffle 45 are installed on the inner wall of the aggregate bin 41. The two limiting strips 46 are arranged in a vertically symmetrical position, and a sealing strip 47 is embedded on the side of the baffle 45 that fits with the limiting strips 46. After the waste enters the aggregate bin 41, the baffle 45 rotates under the action of the adjusting assembly 43 to guide the waste to the discharge port at the lower end of the aggregate bin 41. At the same time, the sealing strip 47 ensures the sealing between the baffle 45 and the limiting strips 46 to prevent waste leakage, realizing the automatic collection and discharge of waste. The structure is simple, the operation is convenient, the sealing performance is good, effectively preventing waste leakage and keeping the working environment clean.

[0031] The adjusting assembly 43 includes an electric push rod 431. The electric push rod 431 is installed at one end of the protective shell 42. The piston rod of the electric push rod 431 is connected with a rack plate 432. A gear 433 is meshed on the surface of the rack plate 432. The center of the gear 433 is fixedly connected with one end of the connecting shaft 44. The electric push rod 431 pushes the rack plate 432 to move. The rack plate 432 drives the gear 433 to rotate. The gear 433 drives the connecting shaft 44 to rotate, thereby controlling the opening and closing angle of the baffle 45 and adjusting the discharge speed of the waste. The precise control of the opening and closing angle of the baffle 45 is realized. The discharge speed of the waste can be adjusted according to actual needs. The operation is convenient and the degree of automation is high.

[0032] A slider 8 is fixedly connected to the lower end of the rack plate 432. A chute 9 is opened at the position corresponding to the slider 8 on the protective shell 42. Through the cooperation of the provided slider 8 and chute 9, a limiting effect can be provided for the moving rack plate 432.

[0033] The cooling mechanism 5 includes a water tank 51 and a filtering component 52. Both the water tank 51 and the filtering component 52 are installed at the bottom of the support frame 1. A water pump 53 is installed on the water tank 51. One of the connecting ports of the water pump 53 is communicated with the water tank 51 through a conduit 54, and the other connecting port of the water pump 53 is communicated with the filtering component 52 through a connecting pipe 55. One side of the filtering component 52 is communicated with a delivery pipe 56. One end of the delivery pipe 56 is communicated with one side of the aggregate tank 41. A flow connection valve 57 is installed on the delivery pipe 56. The water pump 53 pumps out the cooling water in the water tank 51. After being filtered by the filtering component 52, it is delivered to the aggregate tank 41 through the delivery pipe 56 to cool down the waste materials. The flow connection valve 57 can adjust the flow rate of the cooling water. Similarly, when the cooling water finishes cooling the waste materials, the water pump 53 pumps out the cooling water in the aggregate tank 41 again, and then after being filtered by the filtering component 52, it is recycled back into the water tank 51, which can realize the recycling of the cooling water, achieve the rapid cooling of the waste materials, and prevent the waste materials from sticking due to excessive temperature.

[0034] The filtering component 52 includes a filtering box 521. A cover plate 522 is snap-connected to the top of the filtering box 521. A plurality of filter meshes 523 are installed on the lower surface of the cover plate 522 at equal intervals. The mesh sizes of the filter meshes 523 decrease successively from left to right. The cooling water is filtered through multiple filter meshes 523, and the mesh sizes of the filter meshes 523 decrease successively from left to right, which can effectively filter out impurities of different sizes.

[0035] On the opposite sides of the aggregate tank 41 and the water cooling tank 3, grooves 10 are respectively opened. Rollers 11 are rotatably connected in the grooves 10. The rollers 11 facilitate the guiding of the plastics produced by the extrusion machine main body 2, and facilitate the movement into the water cooling tank 3 for cooling and shaping the extruded plastics.

[0036] The aggregate tank 41 is arranged in a funnel shape. The discharge port of the aggregate tank 41 is located directly above the conveying frame 6. The funnel-shaped design is conducive to the concentration and discharge of the waste materials. The discharge port is located directly above the conveying frame 6, which is convenient for the waste materials to fall into the conveying frame 6.

[0037] A controller 12 is installed at one end of the support frame 1 close to the water tank 51. The controller 12 is electrically connected to the extrusion machine main body 2, the waste material treatment device 4, the cooling mechanism 5 and the conveying frame 6 respectively. The controller 12 can control the operation of the extrusion machine main body 2, the waste material treatment device 4, the cooling mechanism 5 and the conveying frame 6, realize the automatic control of the whole system, improve the automation degree of the equipment, reduce the manual operation cost, and improve the production efficiency.

[0038] During specific use, the waste generated by the main body 2 of the extruder is collected in the aggregate bin 41. Through the cooperation of the cooling mechanism 5, the inside of the aggregate bin 41 is filled with cooling water, so as to centrally clean and cool the waste. Subsequently, the cooling water is recycled into the water tank 51 through the cooling mechanism 5 again. During the recycling process, it is filtered by the filtering component 52. The cooling water passes through multiple layers of filter meshes 523. The mesh sizes of the filter meshes 523 decrease successively from left to right, which can effectively filter out impurities of different sizes and enable the recycling of the cooling water. Subsequently, the electric push rod 431 is used to push the rack plate 432 to move. The rack plate 432 drives the gear 433 to rotate, and the gear 433 drives the connecting shaft 44 to rotate, thereby controlling the opening and closing angle of the baffle 45 and adjusting the discharge speed of the waste. The precise control of the opening and closing angle of the baffle 45 is achieved, and the discharge speed of the waste can be adjusted according to actual needs. The operation is convenient and the degree of automation is high. The automatic collection, cooling, filtering, discharging and recycling of the waste are realized, effectively solving the problems that the traditional extruder does not have the function of waste treatment, the low efficiency of manual waste treatment and environmental pollution, etc.
