Description

Technical Field

[0001] The utility model relates to the field of plastic recycling and processing equipment, in particular to a granulator for recycling waste plastics. Background Art

[0002] A plastic granulator is a device used to cut plastic raw materials into small particles. This machine is usually used to reprocess waste plastic products or plastic particles to make them easier to recycle or produce new plastic products. The plastic granulator can process plastic raw materials into particles of different shapes and sizes through processes such as cutting, crushing, and extrusion to meet different production requirements.

[0003] However, in the prior art, during the use of the granulator, due to the lack of a separation structure, multiple plastic strips are likely to adhere to each other during the conveying process, so sticking is likely to occur, which in turn affects the quality of the product.

[0004] Moreover, due to the certain hardness of the plastic strips, the plastic strips are likely to spread and extend to both sides of the guide roller and are difficult to be cut during cutting, which easily leads to uneven cutting and makes it difficult to ensure the uniform cutting of the plastic strips.

[0005] In view of the above technical defects, a solution is now proposed. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a granulator for recycling waste plastics. By setting a guiding component, while avoiding sticking between plastic strips, it also ensures the uniform cutting of plastic strips to solve the technical defects proposed in the background art.

[0007] The purpose of the utility model can be achieved by the following technical solutions: A granulator for recycling waste plastics includes a fixed frame. Inside the fixed frame, a fixed plate is fixedly installed. On the fixed plate, a plurality of guiding plates are fixedly installed. Inside the fixed frame, a guiding component, a guide roller, and a rotating cutter are movably installed. The rotating cutter is located above the guide roller. The fixed plate is located between the guiding component and the guide roller. At one end of the fixed frame close to the guiding component, a liquid drainage plate is fixedly installed. At one end of the fixed frame close to the guide roller, a blanking plate is fixedly installed.

[0008] Preferably, the guiding component includes a rotating roller and guiding grooves. There are a plurality of guiding grooves, and the guiding grooves are evenly spaced on the rotating roller.

[0009] Preferably, a plurality of supporting strips are fixedly installed in the guiding grooves, and a drainage groove is formed by enclosing between the supporting strips.

[0010] Preferably, a moving groove is formed by enclosing between the guiding plates, and the distance between the plurality of guiding plates gradually decreases from the end close to the rotating roller to the end close to the guide roller.

[0011] Preferably, the liquid drainage plate is located below the rotating roller, and the blanking plate is located below the guiding roller.

[0012] Preferably, a plastic strip is placed in the guiding groove. The plastic strip passes through the moving groove and is connected to the rotating roller. A blower is fixedly installed at the top of the fixing frame, and the blower is located above the guiding groove.

[0013] The beneficial effects of the present utility model are as follows:

[0014] (1) By the combined use of the rotating roller and the guiding groove in the present utility model, the plastic strip passes through the guiding groove and the moving groove.

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] Embodiment 1:

[0025] This embodiment is used to solve the problem in the prior art that during the use of a granulator, due to the lack of a separation structure, multiple plastic strips are likely to adhere to each other during transportation, resulting in adhesion, and further affecting the quality of subsequent products.

[0026] Please refer to Figure 1 - Figure 4 As shown, this embodiment is a granulator for recycling waste plastics, including a fixed frame 1. A guiding component 2, a guiding roller 103, and a rotating cutting knife 104 are movably installed in the fixed frame 1. The guiding component 2 includes a rotating roller 201 and a guiding groove 202. A plurality of guiding grooves 202 are provided, and the guiding grooves 202 are evenly spaced on the rotating roller 201. In actual use, the plastic strip 108 passes through the guiding groove 202 and the moving groove 107. During the transportation of the plastic strip 108, the moving groove 107 is used to separate the plastic strips 108 from each other, making it not easy to adhere and ensuring the quality of subsequent products.

[0027] Among them, the rotating cutting knife 104 is located above the guiding roller 103, the fixing plate 101 is located between the guiding component 2 and the guiding roller 103. A liquid discharge plate 105 is fixedly installed at one end of the fixed frame 1 close to the guiding component 2, and a blanking plate 106 is fixedly installed at one end of the fixed frame 1 close to the guiding roller 103. The liquid discharge plate 105 is located below the rotating roller 201, the blanking plate 106 is located below the guiding roller 103. The plastic strip 108 is placed in the guiding groove 202. After passing through the moving groove 107, the plastic strip 108 is connected to the rotating roller 201. A blower 109 is fixedly installed at the top of the fixed frame 1, and the blower 109 is located above the guiding groove 202. A plurality of supporting strips 203 are fixedly installed in the guiding groove 202, and a drainage groove 204 is formed by enclosing between the supporting strips 203.

[0028] At the same time, since the plastic strip 108 needs to be cooled by cooling water after extrusion, there is often residual liquid on the cooled plastic strip 108, which affects subsequent cutting. In this embodiment, when the plastic strip 108 passes through the guide groove 202, the supporting strip 203 is used to lift the plastic strip 108, creating a gap at the bottom of the plastic strip 108, so that the residual liquid on the plastic strip 108 drips into the drainage groove 204. Then, the blower 109 is started to blow air at the plastic strip 108 in the guide groove 202, and the wind is used to promote the residual liquid on the plastic strip 108 to drip from the drainage groove 204 onto the liquid drainage plate 105 and be discharged, thereby cleaning the plastic strip 108.

[0029] Embodiment Two:

[0030] This embodiment is used to solve the problem that since the plastic strip 108 has a certain hardness, the plastic strip is prone to spread and extend to both sides of the guide roller, and it is difficult to be cut during cutting, which easily leads to uneven cutting and it is difficult to ensure the uniform cutting of the plastic strip.

[0031] Please refer to Figure 5 As shown, the present invention further includes a guide plate 102. A fixing plate 101 is fixedly installed inside the fixing frame 1, and a plurality of guide plates 102 are fixedly installed on the fixing plate 101. A moving groove 107 is formed by enclosing between the guide plates 102. The distance between the plurality of guide plates 102 gradually decreases from the end close to the rotating roller 201 to the end close to the guide roller 103.

[0032] The guide plate 102 and the moving groove 107 are used to guide the plastic strip 108, so that multiple plastic strips 108 gradually gather together. The gathered plastic strips 108 are cut into small particles under the action of the guide roller 103 and the rotating cutter 104. Since the plastic strips 108 are gathered, the problem of uneven cutting of the plastic strips 108 during cutting is effectively avoided.

[0033] Combining Embodiment One and Embodiment Two, during the process of conveying the plastic strip 108, the moving groove 107 is used to separate between the plastic strips 108, making it not easy to stick together, ensuring the quality of subsequent products. At the same time, the guide plate 102 and the moving groove 107 are used to guide the plastic strip 108, so that multiple plastic strips 108 gradually gather together. The gathered plastic strips 108 are cut into small particles under the action of the guide roller 103 and the rotating cutter 104. Since the plastic strips 108 are gathered, the problem of uneven cutting of the plastic strips 108 during cutting is effectively avoided.

[0034] The working process and principle of the present invention are as follows:

[0035] Let the plastic strip 108 pass through the moving groove 107. During the process of conveying the plastic strip 108, the moving groove 107 is used to separate between the plastic strips 108, making it not easy to stick together, ensuring the quality of subsequent products;

[0036] Using the guide plate 102 and the moving groove 107, the plastic strips 108 are guided so that multiple plastic strips 108 gradually gather together. Under the action of the guide roller 103 and the rotating cutter 104, the gathered plastic strips 108 are cut into small particles. Since the plastic strips 108 are gathered, the problem of uneven cutting of the plastic strips 108 during cutting is effectively avoided.
