[0002] A high-speed slitting machine is a device used to cut wide roll materials (such as film, paper, and metal coils) into multiple narrower strips. It typically consists of unwinding, slitting, and rewinding sections, and features high precision and sensitivity, making it suitable for slitting various materials. During the slitting process, debris is easily generated, which can affect the slitting process and reduce product quality.

[0003] Existing high-speed slitting machines typically use waste bins to collect waste materials. However, the waste bins on the equipment have limited volume, requiring frequent cleaning by operators during the slitting process, which is inconvenient. If cleaning is not timely, overflowing waste bins can interfere with the normal operation of the equipment. Therefore, those skilled in the art have provided a waste collection device for high-speed slitting machines to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to provide a waste collection device for a high-speed slitting machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A waste collection device for a high-speed slitting machine includes a support frame, a collection box, and an unloading trolley. The support frame has a U-shaped structure. The collection box is rotatably connected between the two vertical sides of the support frame. Ear plates are welded to the middle of the bottom two sides of the collection box. Rotating shaft bolts are threaded onto the two vertical sides of the support frame. The ear plates are rotatably connected to the rotating shaft bolts. An arc-shaped rack is fixedly connected to the middle of one side of the collection box by screws. A support platform is horizontally welded to the top of one side of the support frame. A triangular reinforcing rib is welded between the support platform and the support frame. A stepper motor is fixedly connected to the top of the support platform by bolts. A drive gear is provided at the output end of the stepper motor. The drive gear meshes with the arc-shaped rack. Two guide rails are fixedly connected to the bottom two sides of the support frame by bolts. The unloading trolley is slidably connected to the guide rails.

[0007] As a further embodiment of this utility model: a discharge plate is slidably connected inside the collection box, a guide rod is welded to the bottom center of the discharge plate, a guide sleeve is provided through the bottom center of the collection box, the guide sleeve is slidably connected to the guide rod, a spring is provided around the guide sleeve between the bottom of the discharge plate and the bottom plate of the collection box, a pressure sensor is provided on the side of the guide sleeve, and the height of the guide sleeve at the top of the collection box is the same as the height of the pressure sensor.

[0008] As a further improvement of this utility model, the tail end of the guide rod is connected to a counterweight ring by a thread, and the starting weight of the pressure sensor can be adjusted by replacing the counterweight ring with a different weight.

[0009] As a further improvement of this utility model: the tail end of the arc-shaped rack is fixedly connected to a limiting block by bolts, and a positioning plate is welded to the back of the vertical plate of the support platform on the support frame. When the collection box is in a vertical state, the limiting block is in contact with the positioning plate.

[0010] As a further improvement of this utility model: an electrostatic eliminator fan is provided at the upper back of the collection box, the electrostatic eliminator fan is bolted to the back of the collection box, and the air outlet of the electrostatic eliminator fan is on the same plane as the inner wall of the collection box.

[0011] As a further embodiment of this utility model: magnets are glued to the bottom front of the two vertical sides of the support frame, the tail of the unloading vehicle is magnetically connected to the magnets, a handle is welded to the center of the head of the unloading vehicle, and a wide-mouthed feed chute in the shape of an isosceles trapezoid is provided on the top of the unloading vehicle.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. In this utility model, the support frame is set at the bottom between the cutting wheel and the winding wheel of the high-speed slitting machine. Waste material falls into the collection box. By setting an arc-shaped rack on the side of the collection box and a stepper motor on the side of the support frame, the stepper motor starts every certain period of time or when enough waste material is collected in the collection box. Through the meshing of the drive gear and the arc-shaped rack, the collection box is rotated, and the waste material is poured into the unloading cart and then reset. The capacity of the unloading cart increases the contents of the collection box, reduces the frequency of collection by workers, prevents equipment blockage caused by untimely waste material removal, and improves processing quality.

[0014] 2. In this utility model, a pressure sensor is installed at the bottom of the collection box. When the waste material in the collection box accumulates to a certain mass, the spring is compressed, pressing down the discharge plate so that the bottom of the discharge plate touches the pressure sensor. The pressure sensor transmits a start signal to the stepper motor, causing the collection box to automatically unload and reset. During the unloading process, as the opening of the collection box tilts downwards, the spring resets and pushes the discharge plate to empty the waste material in the collection box as the waste material is poured out. The guide rod is slidably connected to the guide sleeve, and the counterweight pushes the guide rod and the discharge plate to slide with the collection box under the action of gravity, thereby improving the unloading efficiency.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-7 In this embodiment of the present invention, a waste collection device for a high-speed slitting machine includes a support frame 1, a collection box 3, and an unloading trolley 2. The support frame 1 has a U-shaped structure. The collection box 3 is rotatably connected between the two vertical sides of the support frame 1. Ear plates 21 are welded to the middle of the bottom two sides of the collection box 3. Rotating shaft bolts 17 are threadedly connected to the two vertical sides of the support frame 1. The ear plates 21 are rotatably connected to the rotating shaft bolts 17 to facilitate the installation of the collection box 3. An arc-shaped rack 9 is fixedly connected to the middle of one side of the collection box 3 by screws. A support platform is horizontally welded to the top of one side of the support frame 1. 5. A triangular reinforcing rib 6 is welded between the support platform 5 and the support frame 1. A stepper motor 7 is fixedly connected to the top of the support platform 5 by bolts. The output end of the stepper motor 7 is equipped with a drive gear 8, which meshes with an arc-shaped rack 9. Two guide rails 13 are fixedly connected to the bottom sides of the support frame 1 by bolts. A discharge trolley 2 is slidably connected to the guide rails 13. When enough waste is collected in the collection box 3, the stepper motor 7 drives the collection box 3 to discharge into the discharge trolley 2, which indirectly increases the capacity of the collection box 3, prevents the equipment processing from being affected by the inability to clean up the waste in time, and improves product quality.

[0025] The collection box 3 has a slidably connected discharge plate 19 inside. A guide rod 11 is welded to the bottom center of the discharge plate 19. A guide sleeve 10 is installed through the bottom center of the collection box 3. The guide sleeve 10 is slidably connected to the guide rod 11. A spring 22 is installed around the guide sleeve 10 between the bottom of the discharge plate 19 and the bottom plate of the collection box 3. A pressure sensor 23 is installed on the side of the guide sleeve 10. The height of the guide sleeve 10 at the top of the collection box 3 is the same as the height of the pressure sensor 23, protecting the pressure sensor 23 from damage. The pressure sensor 23 is used to start the stepper motor 7 for automated unloading and reduce the frequency of manual operation.

[0026] The tail end of the guide rod 11 is connected to a counterweight ring 12 by a thread. By changing the counterweight ring 12 of different weights, the starting weight of the pressure sensor 23 can be adjusted. By changing the counterweight, the unloading weight of the collection box 3 can be adjusted. The counterweight ring 12 increases the pushing force of the discharge plate 19 during the unloading process, thereby improving the unloading efficiency.

[0027] Among them, the tail end of the arc-shaped rack 9 is fixedly connected to the limit block 20 by bolts. The support frame 1 is provided with a support platform 5 and the back of the vertical plate is welded with a positioning plate 16. When the collection box 3 is in a vertical state, the limit block 20 is in contact with the positioning plate 16. The positioning plate 16 positions the rotation position of the collection box 3, improving the stability of the collection box 3 when it is vertical. The limit block 20 limits the rotation of the collection box 3 to prevent the arc-shaped rack 9 from slipping off the drive gear 8.

[0028] Among them, an electrostatic eliminator fan 4 is installed on the upper back of the collection box 3. The electrostatic eliminator fan 4 is embedded in the back of the collection box 3 by bolts. The air outlet of the electrostatic eliminator fan 4 is on the same plane as the inner wall of the collection box 3. It eliminates the electrostatic charge on waste materials that are easily attracted by static electricity, and prevents the waste materials from adhering to the inner wall of the collection box 3.

[0029] Among them, magnets 18 are glued to the bottom of the front of the two vertical sides of the support frame 1, and the tail of the unloading vehicle 2 is magnetically connected to the magnets 18 to position the unloading vehicle 2. A handle 14 is welded to the center of the head of the unloading vehicle 2, and a wide-mouthed feed chute 15 in the shape of an isosceles trapezoid is provided on the top of the unloading vehicle 2 to prevent waste from spilling out of the unloading vehicle 2 when the collection box 3 is unloading.

[0030] The working principle of this utility model is as follows: The support frame 1 is set at the bottom between the cutting wheel and the winding wheel of the high-speed slitting machine. The unloading carriage 2 is pushed so that the unloading carriage 2 and the magnet 18 on the support frame 1 are magnetically attracted and positioned. The waste generated during processing falls into the vertically positioned collection box 3. As the mass of the waste falling into the collection box 3 increases, the spring 22 is compressed, and the discharge plate 19 is slidably connected to the collection box 3. When the mass of the waste in the collection box 3 reaches the starting critical point, the bottom of the discharge plate 19 contacts the pressure sensor 23. After receiving the starting signal, the stepper motor 7 drives the drive gear 8 to rotate. Due to the meshing of the gear and the arc rack 9, the collection box 3 is driven to rotate until the drive gear 8 contacts the limit block 20. During this process, the waste falls into the unloading carriage 2 along with the tilted collection box 3. As the mass of the waste decreases, the spring 22 returns to its original position, pushing the discharge plate 19 to move towards the opening of the collection box 3 and discharging the waste. When the opening of the collection box 3 faces downwards, the guide rod 11 slides and connects with the guide sleeve 10 under the gravity of the counterweight, increasing the sliding speed of the discharge plate 19 and improving the unloading speed. When the waste passes through the outlet of the collection box 3, the waste is swept away by the electrostatic elimination fan 4 to remove the static electricity on the waste and prevent the waste from being incompletely discharged due to static adsorption in the collection box 3. After a period of time, when all the waste in the collection box 3 has been discharged, the drive motor drives the collection box 3 to reset, so that the collection box 3 is in a vertical state. At this time, the limiting block 20 at the top of the arc rack 9 is in contact with the positioning plate 16 for easy positioning. After the unloading cart 2 is full, the operator pulls the handle 14 to move the unloading cart 2 along the guide rail 13 out of the underside of the high-speed slitting machine for easy collection of waste. It is convenient to use. The unloading cart 2 indirectly increases the volume of the collection box 3, reduces the frequency of worker cleaning, prevents quality degradation caused by untimely waste cleaning, and has high work efficiency.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
