Description

Technical Field

[0001] The utility model relates to the technical field of waste crushing, in particular to a waste crushing device for precision machining. Background Art

[0002] With the rapid development of industrialization, the production and use of precision parts has increased dramatically, generating a large amount of waste. This waste often contains high-value metals and alloys. If directly discarded, it not only wastes resources but also may pollute the environment. Therefore, the crushing and recycling of precision parts waste has important economic and environmental significance.

[0003] When crushing long metal strips of precision parts, the two sets of crushing rollers can easily turn the long metal strips into thin metal strips, which cannot be completely crushed and cannot pass through the crushing of the crushing rollers.

[0004] The utility model with application number CN202120910780.9 provides a waste processing device for precision machining of mechanical parts, which belongs to the technical field of mechanical machining equipment.

The utility model facilitates the recycling of waste and has good functionality and is easy to use.

[0005] This application uses a dust collection mechanism to vacuum the parts after they are crushed to prevent the internal parts from being affected by dust. However, during the crushing process, long parts are likely to pass through the two sets of crushing rollers due to their thin width, and cannot be completely crushed. As a result, the discharge port is easily stuck during discharging, causing problems in the operation of the device.

[0028] like Figures 1 to 6 As shown, a waste crushing device for precision machining includes: a crushing component 2 for crushing waste, a pressing component 3 for pressing the crushed waste, and a discharging component 4 for discharging the crushed waste.

[0029] The crushing assembly 2 includes a first motor 21, a crushing roller 22, and a gear 23; the output end of the first motor 21 is fixedly connected to the crushing roller 22, and two groups of crushing rollers 22 and gears 23 are respectively provided, and the two groups of gears 23 are respectively fixedly connected to the two groups of crushing rollers 22, and the two groups of gears 23 are meshed with each other; the first motor 21 rotates to drive the single crushing roller 22 to rotate, and at the same time, the second group of crushing rollers 22 rotates accordingly, and the precision parts waste falling into the interior of the casing 1 is crushed.

[0030] After the crushing is completed, it is pressed by the pressing assembly 3 to prevent the long metal strip precision parts scrap from being incompletely crushed and its long side not being completely crushed, resulting in inconvenience in discharging. The pressing assembly 3 includes a pressing plate 31, a sliding block 32, a fixed block 33, a transmission rod, and a screening plate 35; the pressing plate 31 is rotatably connected to the sliding block 32, the fixed block 33 is rotatably connected to the pressing plate 31, one end of the transmission rod is rotatably connected to the fixed block 33, and the other end is rotatably connected to the pressing plate 31;

[0031] The sliding block 32, the fixed block 33 and the transmission rod are all provided with multiple groups, and the pressing plate 31 is provided with two groups. The sliding block 32 is slidably connected to the casing 1, and the fixed block 33 is fixedly connected to the casing 1; by placing a cylinder in the casing 1, the two groups of sliding blocks 32 are connected, and the sliding block 32 is driven to rise and fall by the cylinder. When the sliding block 32 is raised and lowered, the fixed block 33 fixes one end of the pressing plate 31, so that the pressing plate 31 rotates along the connection with the fixed block 33, so that the two groups of pressing plates 31 are simultaneously converted from the position attached to the side wall of the casing 1 to the position of pressing the bottom screen plate 35, and the screen plate 35 is pressed.

[0032] As a supplement: the screening plate 35 is in contact with the pressing plate 31, and a plurality of sets of blades are provided on the surface of the screening plate 35, and a plurality of sets of knife grooves are provided at the bottom of the pressing plate 31, which can be adapted to the blades on the surface of the screening plate 35; when the pressing plate 31 is pressed against the screening plate 35, the blades on the screening plate 35 will cut the metal strips that are not completely crushed, and at the same time, the pressing plate 31 presses the metal strips so that the metal strip waste is completely pressed into the inside of the screening plate 35, so that the blades cut the precision parts waste, reducing the probability of discharge jamming.

[0033] The discharging assembly 4 is composed of a second motor 41 and a discharging roller 42; the output end of the second motor 41 is fixedly connected to the discharging roller 42; the discharging roller 42 is driven to rotate by the second motor 41, so that the crushed waste falls into the discharging roller 42, and the rotation of the discharging roller 42 drives the precision parts waste to be discharged for secondary recycling.

[0034] At the same time, the surface of the discharge roller 42 is provided with threaded circles, and the distance between each threaded circle is greater than the diameter of the sieve hole on the surface of the screening plate 35, so that the waste materials after cutting and pressing can adapt to the threaded circles on the discharge roller 42, reducing the probability of the waste materials getting stuck in the discharge roller 42, and at the same time cutting longer waste materials, reducing the stacking pressure of precision parts waste materials, and making effective use of space resources.

[0035] Working principle:

[0036] The single crushing roller 22 is driven to rotate by the rotation of the first motor 21, and the second group of crushing rollers 22 rotates accordingly, and the long metal bars that fall into the interior of the casing 1 are crushed. After the crushing is completed, they are pressed by the pressing component 3 to prevent them from being crushed inadequately. The sliding block 32 is driven to rise and fall by the cylinder. When the sliding block 32 is raised and lowered, the fixed block 33 fixes one end of the pressing plate 31, so that the two groups of pressing plates 31 are simultaneously transferred from the position of being attached to the side wall of the casing 1 to the position of pressing the bottom screening plate 35, and the screening plate 35 is pressed. The discharge roller 42 is driven to rotate by the second motor 41, so that the crushed waste falls into the discharge roller 42, and the waste is discharged by the rotation of the discharge roller 42 for secondary recycling.
