Description

Technical Field

[0001] The invention relates to the technical field of renewable resource crushing, in particular to a renewable resource crushing and recovery device. Background Art

[0002] The resources available to humans can be divided into two categories: non-renewable resources and renewable resources. Renewable resources are a type of renewable resources, which are non-renewable material resources that are developed and utilized once and scrapped in human production, life, science and education, transportation and other activities, and can be repeatedly recycled and processed for reuse. They include steel, non-ferrous metals, rare metals, alloys, inorganic non-metals, plastics, rubber, fibers, paper, etc. that are produced and scrapped with minerals as raw materials.

[0003] Plastics are polymer compounds made from monomers through addition polymerization or condensation polymerization, commonly known as plastics or resins. They can freely change their composition and shape. They are composed of synthetic resins and additives such as fillers, plasticizers, stabilizers, lubricants and colorants. However, when recycling plastics, they often need to be crushed.

[0004] According to a plastic recycling and crushing device for processing renewable resources disclosed in Chinese patent announcement No. CN217834344U, the patent drives the driving gear to rotate through the rotation of the motor, and the driving gear is connected to the first driven gear and the second driven gear through a belt, which facilitates the rotation of the crushing shaft and the rotating shaft. By providing multiple crushing knives and evenly arranging multiple crushing knives on the crushing shaft, it is convenient to crush the plastic and improve the efficiency of plastic crushing. By providing two crushing rollers and the two crushing rollers meshing with each other, the plastic is crushed more thoroughly. By providing a discharge plate, the crushed plastic is convenient to discharge and the work efficiency of the workers is improved. By providing four universal wheels evenly distributed at the bottom four corners of the base, the movement of the device is convenient. By providing a push handle, the movement of the device is more convenient.

Brackets 3 are fixedly installed at the bottom of the four corners of the crushing box 1, and the bottom ends of the four brackets 3 are fixedly installed with feet. The brackets 3 installed at the bottom of the crushing box 1 and the feet provided at the bottom ends of the brackets 3 can start the function of stable support for the entire device.

[0049] The bottom surface of the feed box 2 is connected to the middle part of the top surface of the crushing box 1;

[0050] A crushing assembly 4 is disposed through the crushing box 1;

[0051] The automatic tension adjustment component 5 is arranged in the crushing box 1, and the automatic tension adjustment component 5 is connected to the crushing component 4;

[0052] The screening assembly 6 is located in the crushing box 1 and is connected to the inner wall of the crushing box 1 .

[0053] The crushing assembly 4 comprises:

[0054] The motor 41 is arranged at the rear of the crushing box 1. The output end of the motor 41 is fixedly installed with a first shaft 42. The front end of the first shaft 42 movably penetrates the back of the crushing box 1 and extends into the crushing box 1. The lower surface of the motor 41 is fixedly installed with a motor seat 7. The front of the motor seat 7 is fixedly installed with the back of the crushing box 1. The motor 41 can be stably installed through the installed motor seat 7, which is convenient for the normal operation of the motor 41. The outer wall of the first shaft 42 is fixedly installed with a first gear 43. The first gear 43 is meshed with a second gear 45. The inner wall of the second gear 45 is fixedly installed with a second shaft 44. The second shaft 44 is rotatably arranged with the crushing box 1 through a bearing (the bearing is not drawn in the figure), and another mounting roller 46 is fixedly installed at the front end of the second shaft 44.

[0055] The mounting roller 46 is disposed in the crushing box 1, with both ends of the mounting roller 46 contacting the inner wall of the crushing box 1, and the rear end surface of the mounting roller 46 being fixedly mounted to the front end of the first shaft 42;

[0056] The crushing roller 47 is connected to the mounting roller 46 via the automatic tension adjustment component 5 , and a crushing knife is fixedly mounted on the outer wall of the crushing roller 47 .

[0057] In the specific implementation process, the motor 41 is started to rotate the first shaft 42. Through the first gear 43 and the second gear 45, the second shaft 44 can be made to rotate in the opposite direction to the first shaft 42. Finally, the two installation rollers 46 and the two crushing rollers 47 can be made to rotate in the opposite direction to achieve the purpose of crushing the plastic.

[0058] Example 2

[0059] On the basis of the above embodiment, the tension automatic adjustment component 5 comprises:

[0060] The rubber plate 51 is arranged between the two crushing rollers 47, and the two crushing rollers 47 are fixedly connected by the rubber plate 51. A small spring 53 is arranged between the crushing roller 47 and the mounting roller 46. One end of the small spring 53 is fixedly arranged with the inner surface of the crushing roller 47, and the other end of the small spring 53 is fixedly arranged with the outer surface of the mounting roller 46. The small spring 53 installed between the crushing roller 47 and the mounting roller 46 can promote the recovery trend of the rubber plate 51 and the rubber ring 52, and can also make the crushing roller 47 vibrate slightly, so that the plastic on the crushing roller 47 can be shaken off to avoid being stuck at the crushing knife of the crushing roller 47 and affecting the crushing efficiency;

[0062] In the specific implementation process, during the crushing process, due to the extrusion of multiple plastics, the rubber plate 51 will be deformed, causing the distance between the two crushing rollers 47 to change, so that the plastic can smoothly enter between the two crushing rollers 47, which is convenient for its crushing process. Since the rubber ring 52 is set, it can generate extrusion force during the crushing process, so that the crushing roller 47 forms a forward and backward torsion force, which can strengthen the pulling force on the plastic and enhance the crushing efficiency.

[0063] Example 3

[0064] On the basis of the above embodiment, the screening assembly 6 comprises:

[0065] The screen frame 63 is arranged below the two crushing rollers 47. An obstruction rod 62 is fixedly installed on the top surface of the edge of the screen frame 62, and a rotating rod 61 is arranged above the screen frame 62. One end of the rotating rod 61 is fixedly arranged on the outer wall of the end of the installation roller 46. The length of the rotating rod 61 is greater than the distance between the top of the obstruction rod 62 and the lowest surface of the installation roller 46. In this way, the rotating rod 61 can be smoothly squeezed to the obstruction rod 62 during the rotation process, which is convenient for the reciprocating vibration movement trend of the screen frame 63 in the later stage.

[0066] The auxiliary rod 66 is fixedly mounted on the inner wall of the crushing box 1, and the top surface of the auxiliary rod 66 is slidably arranged with the bottom surface of the screen frame 63. The top surface of the auxiliary rod 66 is provided with a plurality of grooves, and the grooves are slidably provided with a semicircular block 64, and the semicircular block 64 is fixedly mounted on the bottom surface of the screen frame 63;

[0067] One end of the large spring 66 is fixedly mounted on the inner wall of the crushing box 1, and the other end is fixedly mounted on the side of the screen frame 63. There are two large springs 66, which are symmetrically distributed at the front and rear positions with the midline of the front side of the screen frame 63 as the symmetry axis.

[0068] During the specific implementation process, the rotating rod 61 can be rotated by the rotation of the installation roller 46, and then the obstruction rod 62 can be squeezed to move the screen frame 63. The semicircular block 64 and the large spring 66 can realize the vibration of the screen frame 63 during the reciprocating screening process, which can make the plastic remaining on the screen frame 63 move upward, and can be well crushed by the crushing knife on the crushing roller 47, thereby enhancing the crushing force of the plastic.

[0069] Working principle: pour the plastics to be crushed and recycled from the feed box 2 into the crushing box 1, and the first shaft 42 can be rotated when the motor 41 is started, and the first gear 43 can be rotated by the rotation of the first shaft 42, and then the second gear 45 meshing with the first gear 43 can be rotated, and then the second shaft 444 and the first shaft 42 can form a reverse rotation trend, and finally the two crushing rollers 47 can be rotated in the opposite direction to realize the crushing of the plastics. The crushed plastics will fall on the screen frame 63. During the crushing process, due to the extrusion of multiple plastics, the rubber plate 51 will be deformed, and the distance between the two crushing rollers 47 will change, so that the plastics can smoothly enter between the two crushing rollers 47, which is convenient for crushing. Since the rubber ring 52 can generate extrusion force during the crushing process, the crushing rollers 47 form a forward and backward torsion force. In this way, the pulling force on the plastic can be strengthened and the crushing efficiency can be enhanced. The small spring 53 installed between the crushing roller 47 and the mounting roller 46 can promote the recovery trend of the rubber plate 51 and the rubber ring 52, and can also make the crushing roller 47 vibrate slightly, so that the plastic on the crushing roller 47 can be shaken off to avoid being stuck on the crushing knife of the crushing roller 47 and affecting the crushing efficiency. At the same time, the rotating rod 61 will rotate together with the mounting roller 46, and in this process it will squeeze the obstruction rod 62 to move the screen frame 63. Due to the provision of the semicircular block 64 and the large spring 66, the screen frame 63 can be made to move back and forth horizontally and vibrate up and down, which can not only realize the purpose of screening and recovery, but also make the plastic remaining on the screen frame 63 move upward and continue to be crushed by the crushing knife on the crushing roller 47, thereby enhancing the final crushing efficiency.
