Description

Technical Field

[0001] This utility model belongs to the field of label waste treatment technology, specifically relating to a label waste treatment device. Background Technology

[0002] A label is an additional piece of paper or tag used to identify a product. Labels are generally made of paper. Existing label production equipment, such as slitting machines, fully automatic quality inspection machines, and die-cutting equipment, all generate a large amount of label waste in strip or mesh structures.

[0003] The current method generally involves crushing label waste using a shredder. Since the labels contain adhesive, when the shredder blades crush the labels, the adhesive is squeezed out of the label waste and sticks to the blades. If this is not cleaned, it will greatly affect the crushing efficiency of the label waste. Utility Model Content

[0004] The purpose of this invention is to provide a label waste treatment device with a simple structure and reasonable design in order to solve the above problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A label waste processing device includes a crushing box mounted on a support structure. The crushing box contains two crushing rollers, each with blades mounted on its periphery. A drive structure for rotating the crushing rollers is also mounted on one outer wall of the crushing box. Movable plates are positioned between the opposing sides of the two crushing rollers and the inner wall of the crushing box. Brushes are fixedly mounted on the sides of the two movable plates near the crushing rollers. Sliding rods are connected to both ends of the movable plates away from the brushes. The sliding rods penetrate the side wall of the crushing box and are slidably connected to it. A compressed spring is fitted onto the section of the sliding rod inside the crushing box, with both ends of the spring fixed to the inner wall of the crushing box and the movable plate, respectively. An adjusting nut is screwed onto the section of the sliding rod outside the crushing box.

[0007] As a further optimization of this utility model, the support structure includes a support platform provided below the crushing box, and a set of legs are fixedly connected to both ends of the lower surface of the support platform, with a horizontal beam installed between two legs in each set.

[0008] As a further optimization of this utility model, a hopper communicating with the inner cavity of the crushing box is fixedly connected to the top wall of the crushing box, and a discharge pipe communicating with the inner cavity of the crushing box is fixedly connected to the bottom end of the crushing box. The bottom of the discharge pipe passes through the support platform and is fixed to the support platform.

[0009] As a further optimization of this utility model, the drive structure includes two gears arranged on the outer wall of the crushing box, the two gears meshing with each other, and a linkage shaft fixedly connected to the side of each gear near the crushing box. The two linkage shafts pass through and are rotatably connected to the side wall of the crushing box and are fixed to the end of the corresponding crushing roller.

[0010] As a further optimization of this utility model, the two gear covers are provided with gearboxes that are fixedly connected to the outer wall of the crushing box. A motor is installed on the gearbox, and the output end of the motor extends into the gearbox and is fixedly connected to one of the gears.

[0011] As a further optimization of this utility model, two symmetrically arranged baffles are fixedly connected to the top wall of the inner cavity of the crushing box below the hopper, and a gap smaller than the thickness of the label is left between the bottom of the baffle and the blade.

[0012] The beneficial effects of this utility model are as follows: When in use, the label waste is fed into the crushing box for crushing. When the label waste is squeezed by the blade, the adhesive in the label waste will be squeezed out and the label waste fragments will adhere to the blade. As the crushing roller continues to drive the blade to rotate, when the blade rotates to the brush position, the brush bristles are in contact with the blade, which can clean the waste fragments adhering to the blade. This avoids the problem of the crushed label waste sticking to the blade, which would greatly affect the crushing efficiency of the label waste. Attached Figure Description

[0018] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0019] Example

[0020] like Figure 1 - Figure 4 As shown, the label waste treatment device includes a crushing box 4 installed on a support structure. The support structure includes a support platform 1 set below the crushing box 4. A set of legs 2 are fixedly connected to both ends of the lower surface of the support platform 1. A crossbeam 3 is horizontally installed between the two legs 2 in each set. The support platform 1 and the legs 2 are set to support the crushing box 4 to a suitable height. The crossbeam 3 is set to reinforce the legs 2 and improve the stability of the support of the legs 2.

[0021] The top wall of the crushing box 4 is fixedly connected to a hopper 6 that communicates with the inner cavity of the crushing box 4. The bottom end of the crushing box 4 is fixedly connected to a discharge pipe 5 that communicates with the inner cavity of the crushing box 4. The bottom of the discharge pipe 5 passes through the support platform 1 and is fixed to the support platform 1. When using the crushing box 4, the user can feed the label waste into the crushing box 4 through the hopper 6. After crushing, the waste is discharged through the discharge pipe 5.

[0022] The crushing chamber 4 contains two crushing rollers 7, each with blades 8 mounted on its periphery. A drive structure for rotating the crushing rollers 7 is also installed on one outer wall of the crushing chamber 4. This drive structure includes two gears 10 mounted on the outer wall of the crushing chamber 4, which mesh with each other. A linkage shaft 11 is fixedly connected to the side of each gear 10 near the crushing chamber 4. Both linkage shafts 11 pass through and rotatably connect to the side wall of the crushing chamber 4, and are then fixed to the ends of the corresponding crushing rollers 7. The gears 10 are covered with a casing that is fixedly connected to the outer wall of the crushing chamber 4. The gearbox 9 has a motor 12 installed on it. The output end of the motor 12 extends into the gearbox 9 and is fixedly connected to one of the gears 10. After the label waste is fed into the crushing box 4 through the hopper 6, the waste slides down above the two crushing rollers 7 under the action of gravity. At this time, the motor 12 is turned on, and the motor 12 drives the two gears 10 in the gearbox 9 to rotate in opposite directions. This drives the two crushing rollers 7 to rotate synchronously through the linkage shaft 11. The blades 8 installed on the two crushing rollers 7 squeeze the label waste in opposite directions, thus realizing the crushing of the label waste.

[0023] Two symmetrically arranged baffles 13 are fixedly connected to the top wall of the inner cavity of the crushing box 4 below the hopper 6. A gap smaller than the label thickness is left between the bottom of the baffle 13 and the blade 8. The baffle 13 can block the label waste that is introduced into the crushing box 4 through the hopper 6, and try to avoid the label waste from sliding off the two crushing rollers 7 on the side that is far apart, which would cause the label waste to be unable to be crushed.

[0024] Movable plates 14 are provided between the opposite sides of the two crushing rollers 7 and the inner wall of the crushing chamber 4. Brushes 15 are fixedly installed on the side of the two movable plates 14 closest to the crushing rollers 7. Slide rods 16 are connected to both ends of the movable plates 14 away from the brushes 15. The slide rods 16 penetrate the side wall of the crushing chamber 4 and are slidably connected to it. A compressed spring 17 is fitted onto the section of the slide rod 16 inside the crushing chamber 4. The two ends of the spring 17 are fixed to the inner wall of the crushing chamber 4 and the movable plate 14, respectively. An adjusting nut 18 is screwed onto the section of the slide rod 16 outside the crushing chamber 4.

[0025] It should be noted that, when using this label waste processing device, after the label waste is fed into the crushing box 4 through the hopper 6, the waste slides down above the two crushing rollers 7 under the action of gravity. At this time, the label waste is blocked by the baffles 13 on both sides and is between the two crushing rollers 7. Then the motor 12 can be turned on, and the motor 12 drives the two gears 10 in the gearbox 9 to rotate in opposite directions, thereby driving the two crushing rollers 7 to rotate synchronously through the linkage shaft 11. The label waste is crushed by the blades 8 installed on the two crushing rollers 7 squeezing it in opposite directions. The crushed label waste is discharged through the discharge pipe 5 installed at the bottom of the crushing box 4.

[0026] When the label waste is squeezed by the blade 8, the adhesive inside the label waste will be squeezed out and the label waste fragments will adhere to the blade 8. As the crushing roller 7 continues to drive the blade 8 to rotate, when the blade 8 rotates to the position of the brush 15, the brush bristles of the brush 15 are in contact with the blade 8, which can clean the waste fragments stuck to the blade 8, and try to avoid the label waste after crushing sticking to the blade 8, which will greatly affect the crushing efficiency of the label waste.

[0027] When the bristles of brush 15 wear down due to prolonged friction with the blade 8 and are unable to clean label waste debris, the user can screw the adjusting nut 18 at the end of slide rod 16 located outside the crushing box 4. This causes spring 17 to push movable plate 14 towards crushing roller 7 under its own elastic force, so that the bristles of brush 15 continue to adhere to the blade 8 to clean the blade 8. This eliminates the need for frequent replacement of brush 15 and makes it convenient for users.

[0028] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
