Description

Technical Field

[0001] The utility model relates to the technical field of crushing equipment, in particular to a plastic crushing device. Background Art

[0002] Crushing equipment generally includes a crushing box and crushing rollers arranged inside it, which can be used to crush plastic materials, such as crushing plastic waste generated during the processing process, which can then be more conducive to the recycling of the waste. The crushing box of the crushing equipment is generally provided with a feed hopper for the waste to enter. A pair of crushing rollers arranged in the crushing box are located below the feed hopper. The material falls between the two crushing rollers, and the two crushing rollers bite into each other to bite into the material and tear the material into pieces, thereby achieving the purpose of crushing. In the actual operation process, for some long strips of plastic waste of varying lengths, after being put into the feed hopper, some shorter waste can be easily bitten into the crushing rollers, while longer waste may take longer to be bitten into. Therefore, in order to ensure smooth feeding, sorting is required in advance, which increases the time. It also takes longer to crush longer waste, so the overall crushing efficiency cannot be improved. Utility Model Content

[0003] In view of the deficiencies in the prior art, the present invention provides a plastic crushing device, which solves the problem of low overall efficiency in crushing plastic waste of different lengths in the prior art.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0021] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like to indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation to the present invention.

[0022] In an exemplary embodiment, Figure 1 、 2 As shown, this embodiment provides a plastic crushing device, which includes a crushing box 1, and a feed hopper 2 connected to the inner side of the crushing box 1 is fixedly connected to one side of the upper end thereof, a pair of mutually interlocking first crushing rollers 3 located below the feed hopper 2 is installed in the crushing box 1, and a pair of mutually interlocking second crushing rollers 4 is installed in the feed hopper 2, the two first crushing rollers 3 are horizontally opposed to each other, and the two second crushing rollers 4 are vertically opposed, and the two first crushing rollers 3 and the two second crushing rollers 4 are enclosed into a U-shaped structure with an opening facing the outside of the feed hopper 2, and the first crushing rollers 3 and the second crushing rollers 4 are arranged separately.

[0023] In the above embodiment, the feed hopper 2 is tilted, which is convenient for feeding. The U-shaped structure allows the material to be partially bitten by the second crushing roller 4 in the feed hopper 2, and the second crushing roller 4 is located on the higher side of the feed hopper 2. In this way, when crushing, the waste does not need to be sorted and is directly put in. The first crushing roller 3 and the second crushing roller 4 bite the material at two positions at the same time, which can make longer waste materials also be bitten smoothly, thereby improving the overall crushing efficiency, and solving the problem of low overall efficiency when crushing plastic waste of different lengths in the prior art; further In the scheme, a pair of third crushing rollers 5 that bite each other are also installed in the crushing box 1. The third crushing roller 5 is located below the two second crushing rollers 4. The waste materials bitten into the feed hopper 2 are generally longer waste materials. After being crushed by the second crushing rollers 4, they may still be longer. Therefore, after they enter the crushing box 1, they are bitten by the third crushing roller 5 below for crushing again, ensuring that the crushing effect is better. The waste materials crushed by the first crushing rollers 3 and the third crushing rollers 5 fall into the material receiving box 6 arranged below for collection. The arranged material receiving box 6 can be pulled out from the lower end of the crushing box 1, which is convenient for taking and putting to recycle the crushed waste.

[0024] like Figure 1 As shown, in a more detailed scheme, a first baffle 7 is fixedly connected to the crushing box 1. After passing through the two second crushing rollers 4, the material falls downward and is guided through the first baffle 7 to between the two third crushing rollers 5. The first baffle 7 separates the first crushing roller 3 and the third crushing roller 5 to prevent the waste material passing through the second crushing roller 4 from falling directly below. Furthermore, a second baffle 8 is fixedly connected to the crushing box 1. The second baffle 8 is connected to one side of the feed hopper 2. The second baffle 8, the two second crushing rollers 4, the first baffle 7 and the feed hopper 2 together form a material guide channel, so that the waste material passes through the two second crushing rollers 4 to between the two third crushing rollers 5. This scheme arranges the first crushing roller 3, the second crushing roller 4 and the third crushing roller 5 so that the waste material can be efficiently crushed without sorting, thereby improving the overall crushing efficiency.

[0025] like Figure 1 、 2 As shown in a further detailed scheme, a drawing port is provided on the side wall at the lower end of the crushing box 1, and the material receiving box 6 enters and exits the crushing box 1 through the drawing port. A first stop bar 10 opposite to the drawing port and a pair of second stop bars 11 located outside the two ends of the first stop bar 10 are also fixedly connected to the crushing box 1. The first stop bar 10 and the two second stop bars 11 are enclosed in a horizontal shape and are respectively connected to the inner wall of the crushing box 1. The top surface of the side wall of the material receiving box 6 is in sliding contact with the bottom surfaces of the first stop bar 10 and the second stop bar 11. The first stop bar 10 and the second stop bar 11 are provided to play a transition role between the material receiving box 6 and the inner wall of the crushing box 1, preventing waste from piling up on the top surface of the side wall of the material receiving box 6, and at the same time providing a guide for the material receiving box 6 so that its drawing process can be more convenient. The second inclined surface 13 makes it easier for the material receiving box 6 to enter under the first baffle 10, so that after the material receiving box 6 is pushed into the crushing box 1, it is restricted by the first baffle 10 and the second baffle 11 at the top and is more stable. In order to facilitate the pulling and drawing, the material receiving box 6 is also connected with a handle 9 located outside the drawing port.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
