[0029] 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.

[0030] Please refer to the following: Figures 1-6 As shown, this utility model provides a plastic bottle crushing and washing integrated machine that can automatically clean impurities, including a crushing box 100, a pair of crushing rollers 101 installed in the crushing box 100, the crushing rollers 101 having blades (not shown in the figure), the pair of crushing rollers 101 can rotate in opposite directions by an external motor, and a feed inlet 102 for feeding plastic bottles is provided on the upper side of one side of the crushing box 100 and a discharge outlet 103 for discharging crushed plastic is provided on the lower side of one side;

[0031] It also includes a guide platform 200, a lower pressure plate 201, and a water spray pipe 203. The guide platform 200 is configured as a pair, located on a pair of crushing rollers 101 respectively. The two guide platforms 200 face each other to form an inverted "V" shaped storage space. The quantitative plastic bottles introduced by the feed inlet 102 can gather between the pair of crushing rollers 101 after passing through the guide platform 200. As the crushing rollers 101 rotate, the plastic bottles are torn and crushed to form recyclable plastic fragments.

[0032] The lower pressure plate 201 is placed inside the crushing box 100. It can be driven by an external control component to move back and forth along the height direction of the crushing box 100 to squeeze the plastic bottle tightly between a pair of crushing rollers 101, thereby preventing the plastic bottle from rebounding and improving the crushing effect.

[0033] The water spray pipe 203 is installed on the lower pressure plate 201. During the crushing operation, it can form a spray of liquid at the output section. This liquid can be cleaning water. The cleaning water liquid can be poured between a pair of crushing rollers 101 to achieve the purpose of dust reduction during crushing, as well as washing and cooling the crushing rollers 101 and plastic fragments, reducing material adhesion and improving the uniformity of plastic crushing. At the same time, as the liquid flows downward, it can also drive the crushed fragments to move together, forming a promoting effect on the discharge of crushed fragments.

[0034] Furthermore, the lower pressure plate 201 is in the shape of an equilateral triangle, with its tip pointing downwards and directly facing the crushing space between the pair of crushing rollers 101. This ensures that the lower pressure plate 201 can retain its ability to squeeze the plastic bottle between the pair of crushing rollers 101 during the lifting and lowering process, while also not touching the blades of the pair of crushing rollers 101, thus improving the safety of the operation.

[0035] Furthermore, both sides of the lower pressure plate 201 face their respective adjacent guide platforms 200, and the sides of the lower pressure plate 201 and the surface of the guide platform 200 form a feeding space, the width of which gradually decreases from high to low. That is to say, as the plastic bottle is introduced from the feed inlet 102 to the crushing roller 101, the width of the feeding space decreases. This space facilitates the guidance of the plastic bottle, and allows plastic bottles that are not in a crushing state when the lower pressure plate 201 is pressed down to partially slide upward or be directly flattened during the compression process of the lower pressure plate 201 and the guide platform 200. After the lower pressure plate 201 moves down to its maximum stroke, there is a certain space between it and the guide platform 200 reserved for uncrushed plastic bottles. In other words, the above-mentioned feeding space can prevent too many plastic bottles from interfering with the movement of the lower pressure plate 201, ensuring the pressing stability of the lower pressure plate 201 and improving the crushing efficiency of the crushing roller 101.

[0036] Furthermore, the control component for moving the lower pressure plate 201 is an electric push rod 202. Specifically, an electric push rod 202 is installed at the top of the crushing box 100. The output shaft of the electric push rod 202 passes through and is slidably connected to the top of the crushing box 100, and is fixedly connected to the top plane of the lower pressure plate 201. Through the action of the electric push rod 202, the reciprocating extension and retraction of its output shaft can be realized, which means that the vertical reciprocating movement of the lower pressure plate 201 can be realized. The vertical reciprocating movement of the lower pressure plate 201 allows the plastic bottle to enter the junction of the pair of crushing rollers 101 when it moves upward, and when the lower pressure plate 201 moves downward, it pushes some of the plastic bottles that will rebound downward into the space between the pair of crushing rollers 101 to improve its crushing stability.

[0037] Furthermore, two water spray pipes 203 are configured and installed on both sides of the lower pressure plate 201 respectively. The output of the water spray pipes 203 faces the inclined surface of the guide table 200. During the crushing operation, the spraying action of the two water spray pipes 203 can spray liquid onto the guide table 200, forming a flush on the guide table 200, reducing the adhesion of plastic fragments. The flushed liquid moves downward with gravity. During this process, the crushing roller 101 can also be rinsed and cooled, and plastic impurities on the crushing roller 101 can be flushed away. At the same time, dust during the crushing process is reduced, improving operational safety. Finally, the mixed liquid composed of washing water, plastic fragments and dust can be discharged together from the discharge port 103.

[0038] Furthermore, a set of piston tubes 204 located on one side of the electric push rod 202 are fixedly installed on the top of the lower pressure plate 201. Each set of piston tubes 204 has multiple piston tubes. A piston rod 205 is installed inside the piston tube 204. The rod part of the piston rod 205 is fixedly connected to the top inner wall of the crushing box 100. The tail of the piston tube 204 is connected to an external water source through a set of one-way water inlet valve pipes. The tail is also connected to the water spray pipe 203 through a set of one-way water outlet valve pipes. The above is the piston structure in the prior art. For details, please refer to the piston cylinder structure in the automotive field. It will not be described in detail here.

[0039] The difference is that, based on the reciprocating vertical movement of the lower pressure plate 201, it can also drive the piston tube 204 to move synchronously, thereby forcing the piston rod 205 to repeatedly do work in the piston tube 204, thereby drawing external liquid into the piston tube 204 through the one-way water inlet valve, and then inputting it into the water spray pipe 203 through the one-way water outlet valve, realizing the spraying action of the water spray pipe 203. By using the same driving action, the cost of accessories is reduced, which is more cost-effective than using a pump body.

[0040] Furthermore, the top of the lower pressure plate 201 is also provided with a set of piston tubes 204 located on the other side of the electric push rod 202, and each set of piston tubes 204 has multiple piston tubes; the piston tubes 204 are fixedly connected to the top inner wall of the crushing box 100, and the piston tubes 204 are equipped with the same piston rods 205, the rod part of the piston rods 205 being fixedly connected to the top of the lower pressure plate 201; wherein, the head of the piston tube 204 is connected to an external water source through a set of one-way water inlet valves, and the head is also connected to the spray pipe 203 through a set of one-way water outlet valves, the head position referring to the position adjacent to the pipe opening of the piston tube 204; the structure here is completely consistent with the structure of the piston tubes 204, etc.

[0041] The difference is that the two sets of piston tubes 204 in this application have different tube openings (upward and downward), which means that the upward and downward movement of the lower pressure plate 201 can make the two water spray pipes 203 spray liquid alternately. On the one hand, it can reduce liquid waste; on the other hand, there is always liquid falling between the pair of crushing rollers 101, which ensures the dust reduction effect during continuous crushing and the cleaning and cooling of the crushing rollers 101.

[0042] Furthermore, the bottom inner wall of the crushing box 100 is inclined, with the lower end facing the discharge port 103; a washing pool 300 with a top opening is also installed on one side of the crushing box 100. The washing pool 300 is located directly below the discharge port 103 and is used to receive and wash the crushed plastic fragments; the mixed liquid containing dust and plastic fragments will fall into the bottom of the crushing box 100 and enter the washing pool 300 from the discharge port 103 to further clean the plastic fragments.

[0043] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
