DETAILED DESCRIPTION

[0021] The following is a further detailed description of the implementation of the present utility model in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0022] In the description of the present invention, unless otherwise specified, "multiple" means two or more; the terms "upper", "lower", "left", "right", "inner", "outer", "front end", "rear end", "head", "tail" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, which is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", "third" and the like are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0023] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] like Figure 1-5 As shown, the utility model provides a technical solution: a device for uniformly cutting blister materials, comprising a tank body 1, a bracket 2 is fixedly installed on the top of the tank body 1, a motor 3 is fixedly installed on the top of the bracket 2, a rotating shaft 4 is fixedly installed on the output end of the motor 3, the rotating shaft 4 passes through the bracket 2, and the outer wall of the rotating shaft 4 is rotatably connected to the bracket 2 through a bearing, a cutting knife 6 is fixedly installed on the outer wall of the rotating shaft 4, and a screening mechanism 5 is arranged at the bottom of the rotating shaft 4;

[0025] The screening mechanism 5 includes a screening plate 601, a connecting shaft 603 is fixedly installed on the top of the screening plate 601, a shaft groove 602 is opened at the bottom of the rotating shaft 4, the connecting shaft 603 is inserted into the shaft groove 602, a spring 604 is fixedly connected between the top of the connecting shaft 603 and the top of the inner wall of the shaft groove 602, the screening plate 601 is slidably connected to the inner wall of the tank body 1, a protrusion 2 607 is fixedly installed on the bottom of the screening plate 601, a fixing ring 605 is arranged below the screening plate 601, and a protrusion 1 606 is fixedly installed on the top of the fixing ring 605.

[0026] Specifically, the above technical solution is as follows: plastic and metal grinding particles are added from the top of the tank body 1, and then the motor 3 is started. The motor 3 drives the rotating shaft 4 to rotate, and the rotating shaft 4 drives the cutting knife 6 to rotate, so that the cutting knife 6 breaks the plastic. When the rotating shaft 4 rotates, it drives the connecting shaft 603 to rotate through the shaft groove 602, and the connecting shaft 603 drives the screening plate 601 to rotate. The screening plate 601 drives the second protrusion 607 to make a circular motion, so that the second protrusion 607 and the first protrusion 606 are in reciprocating contact. When the first protrusion 606 contacts the second protrusion 607, the screening plate 601 will move upward, so that the connecting shaft 603 squeezes the spring 604. When the second protrusion 607 is not in contact with the first protrusion 606, the connecting shaft 603 will be in the spring. The resetting force of 604 drives the screening plate 601 to move downward, so that the screening plate 601 can vibrate up and down, avoiding the accumulation of plastic particles on the screening plate 601, and ensuring the screening efficiency of the screening plate 601. The crushed plastic particles can be screened through this mechanism to ensure the uniformity of the size of the crushed plastic particles. The screening plate 601 will vibrate up and down during use to avoid the accumulation of plastic particles on the screening plate 601, and ensuring the screening efficiency of the screening plate 601. This solves the problem that the crushing tank in the prior art solution does not have a structure for screening the crushed plastic particles, resulting in the possibility of larger-sized plastics therein, which need to be screened manually, with high labor intensity and inconvenience in use.

[0027] Furthermore, the number of the first bump 606 and the second bump 607 are both multiple, and the first bump 606 and the second bump 607 are arranged alternately;

[0028] Among them, by setting the protrusion 1 606 and the protrusion 2 607, the screening plate 601 can be vibrated up and down.

[0029] Furthermore, the cross-sections of the connecting shaft 603 and the shaft groove 602 are both rectangular, and the connecting shaft 603 and the shaft groove 602 are adapted to each other;

[0030] By setting the cross-sections of the connecting shaft 603 and the shaft groove 602 to be rectangular, the rotating shaft 4 can drive the connecting shaft 603 to rotate through the shaft groove 602, thereby driving the screening plate 601 to rotate.

[0031] Furthermore, a compartment box 7 is fixedly mounted on the top of the bracket 2, and the motor 3 is arranged inside the compartment box 7;

[0032] The partition box 7 can provide a certain degree of protection for the motor 3 and ensure the normal service life of the motor 3.

[0033] Furthermore, the bottom end of the tank body 1 is connected to a discharge pipe 8, and a protective cover 12 is fixedly installed on the top of the screening plate 601, and the protective cover 12 is movably sleeved on the outer wall of the rotating shaft 4;

[0034] Among them, by setting up a protective cover, a certain protective effect can be played between the connecting shaft 603 and the rotating shaft 4, preventing the plastic particles from affecting the normal vibration of the screening plate 601.
