Description

Technical Field

[0001] This utility model relates to the field of die-cutting machine technology, specifically to an environmentally friendly collection device for die-cutting waste. Background Technology

[0002] When processing beverage packaging boxes (such as milk carton), the packaging paper needs to undergo processes such as printing, die-cutting, folding, and gluing. The die-cutting process uses a rotary die-cutting machine. A rotary die-cutting machine consists of upper and lower die-cutting rollers, which are the direct executors of the rotary die-cutting process. The embossed patterns on the upper die-cutting rollers work closely with the lower die-cutting rollers, cutting the packaging paper through pressure.

[0003] Waste is generated after the packaging paper is die-cut. The waste is collected by a collection device to prevent it from scattering in the working environment and to protect the working environment.

[0004] See Figure 1 The current collection device includes a collection hopper 1 and a guide plate 2. The collection hopper 1 is fixedly installed on the ground, and its bottom is connected to a discharge pipe 11, which is connected to the inlet of the dust collector. The top of the guide plate 2 is fixedly installed on the body of the rotary die-cutting machine 3 by bolts, and the body of the rotary die-cutting machine 3 is fixedly installed on the frame 4 by bolts. The bottom of the guide plate 2 overlaps the top of the collection hopper 1.

[0005] See Figure 2 The packaging paper after being die-cut by the rotary die-cutting machine 3 is conveyed to the next process via the conveyor frame 5. At the same time, the waste generated by die-cutting is guided by the guide plate 2 and slides into the collection hopper 1. A fan is installed in the dust collector. The waste entering the collection hopper 1 is drawn into the dust collector through the discharge pipe 11 by the suction action of the fan.

[0006] The above-mentioned collection device also has the following shortcomings: Since the top of the guide plate is fixed to the body of the rotary die-cutting machine by bolts, there is a height difference between the top of the guide plate and the lower die-cutting roller. The top space of the guide plate forms a waste discharge dead angle, which makes it easy for waste to accumulate on the top of the guide plate, reducing the waste collection effect and thus reducing the environmental protection effect. Utility Model Content

[0007] This invention addresses the aforementioned shortcomings of existing technologies by proposing an environmentally friendly collection device for die-cutting waste. This invention can prevent waste from accumulating on the top of the guide plate, thereby improving the collection effect of waste and enhancing environmental protection.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0009] An environmentally friendly collection device for die-cutting waste includes a collection hopper and a guide plate. An extension plate is slidably connected to the upper part of the guide plate. An elastic element is provided on the upper part of the guide plate for pushing the extension plate upward. The top of the extension plate abuts against the roller surface of the lower die-cutting roller in a rotary die-cutting machine. The lower part of the guide plate is rotatably connected to the top of the collection hopper. An adjustment mechanism is provided on the collection hopper for adjusting the tilt angle of the guide plate.

[0010] Furthermore, the guide plate has a guide side on its side, and the guide side has a sliding cavity. The extension plate has an extension side on its side, and the extension side has a slider. The slider is located in the sliding cavity. The elastic element is located in the sliding cavity. The top of the elastic element abuts against the slider, and the bottom of the elastic element abuts against the bottom of the sliding cavity.

[0011] Furthermore, a guide rod is provided inside the sliding cavity, the slider is slidably connected to the guide rod, and the elastic element is a spring, which is sleeved on the guide rod.

[0012] Furthermore, the adjustment mechanism includes an adjustment rod, a clamping plate, a screw, and a limiting member. The top of the adjustment rod is connected to the bottom of the guide plate, and the bottom of the adjustment rod is bent toward the side of the collecting hopper to form a bent rod. The side of the collecting hopper is provided with an arc-shaped hole, and the bent rod is provided with a clamping plate at one end near the arc-shaped hole. A screw is provided on the clamping plate, and the screw passes through the arc-shaped hole. A limiting member is threaded onto the screw, and the side of the collecting hopper is clamped between the limiting member and the clamping plate.

[0013] Furthermore, the limiting component is a nut.

[0014] Furthermore, the screw has a handle at the end away from the clamping disc.

[0015] The beneficial effects of this utility model are:

[0016] 1. Because the guide plate is rotatably mounted on top of the collection hopper, and its tilt can be adjusted by the adjustment mechanism, the extension plate at the top of the guide plate can be oriented towards the lower die-cutting roller. Furthermore, because the extension plate can slide upwards under the push of the elastic element, the top of the extension plate can abut against the roller surface of the lower die-cutting roller in the rotary die-cutting machine. In this state, the extension plate compensates for the height difference between the top of the guide plate and the lower die-cutting roller, eliminating any dead corners for waste disposal at the top of the guide plate. This prevents waste from accumulating on the top of the guide plate, allowing it to slide smoothly along the extension plate and guide plate into the collection hopper, improving waste collection efficiency and contributing to environmental protection.

[0017] 2. In a rotary die-cutting machine, the distance between the upper and lower die-cutting rollers needs to be adjusted according to the thickness of the packaging paper, causing the height of the lower die-cutting roller to change. In this invention, because the extension plate can move relative to the guide plate under the push of the elastic element, even if the height of the lower die-cutting roller changes, the extension plate can still abut against the roller surface of the lower die-cutting roller to maintain contact. This allows the extension plate to still compensate for the height difference between the top of the guide plate and the lower die-cutting roller, preventing waste from accumulating on the top of the guide plate and ensuring effective waste collection and environmental protection.

[0018] 3. By adjusting the tilt angle of the guide plate using an adjustment mechanism, the efficiency of die-cutting waste falling from the guide plate into the collection hopper can be adjusted. For example, the steeper the tilt of the guide plate, the faster the waste slides over the guide plate, resulting in a faster entry of the waste into the collection hopper and improving the collection efficiency. This enhances the flexibility of the collection device of this invention.

[0019] 4. Because the bottom of the guide plate is rotatably connected to the top of the collection hopper, and the adjustment mechanism can adjust the tilt angle of the guide plate, the guide plate does not need to be fixed to the body of the rotary die-cutting machine with bolts. Therefore, when replacing the rotary die-cutting machine, the guide plate can be reused, and there is no need to configure a separate guide plate for each rotary die-cutting machine, which improves the adaptability of the collection device of this utility model.

[0020] 5. In this utility model, because the screw in the adjusting mechanism is located in the arc-shaped hole on the side of the collecting hopper, the worker can operate from the side of the collecting hopper when swinging the screw in the arc-shaped hole. The side space of the collecting hopper is ample, making operation convenient. Furthermore, the handle provides a gripping position for the worker, making it even more convenient to use.

Therefore, they should not be construed as limitations on this utility model.

[0039] Example:

[0040] See Figures 3 to 8 An environmentally friendly collection device for die-cutting waste includes a collection hopper 1, a guide plate 2, an extension plate 6, an elastic element, and an adjustment mechanism.

[0041] The side of the guide plate 2 is provided with a guide side 21. The guide side 21 and the guide plate 2 are an integral structure. The guide side 21 is provided with a sliding cavity 211. The sliding cavity 211 is provided with a guide rod 2111. The upper and lower ends of the guide rod 2111 are welded and fixed to the top and bottom of the sliding cavity 211, respectively.

[0042] The side of the extension plate 6 is provided with an extension side 61. The extension plate 6 and the extension side 61 are an integral structure. A slider 611 is welded on the extension side 61. The slider 611 is located in the sliding cavity 211. The slider 611 is provided with a through hole. The through hole is penetrated by the guide rod 2111. The slider 611 and the guide rod 2111 slide in cooperation.

[0043] The elastic element can be a spring 7, which is located in the sliding cavity 211 and sleeved on the guide rod 2111. The top of the spring 7 abuts against the slider 611, and the bottom of the spring 7 abuts against the bottom of the sliding cavity 211. The spring 7 is used to push the extension plate 6 upward so that the top of the extension plate 6 abuts against the roller surface of the lower die-cutting roller 31 in the rotary die-cutting machine 3.

[0044] A first rotating seat is welded to the lower part of the guide plate 2, and a second rotating seat 12 is welded and fixed to the top of the collection hopper 1. The first rotating seat is rotatably connected to the second rotating seat 12 through a pin 22.

[0045] The adjustment mechanism is used to adjust the tilt angle of the guide plate 2. The adjustment mechanism includes an adjustment rod 81, a clamping plate 82, a screw 83, and a limiting component. The top of the adjustment rod 81 is welded and fixed to the bottom of the guide plate 2. The bottom of the adjustment rod 81 is bent towards the side of the collecting hopper 1 to form a bent rod 811. A clamping plate 82 is welded to the end of the bent rod 811 near the arc-shaped hole 13. The side of the collecting hopper 1 has an arc-shaped hole 13 centered on the pin 22. A screw 83 is welded to the clamping plate 82, and the screw 83 passes through the arc-shaped hole 13. The limiting component is a nut 84, which is threadedly connected to the screw 83. The side of the collecting hopper 1 is clamped between the nut 84 and the clamping plate 82. A handle 85 is also welded to the end of the screw 83 away from the clamping plate 82.

[0046] The working principle of this embodiment is as follows:

[0047] Because the guide plate 2 is rotatably mounted on top of the collection hopper 1, and the tilt of the guide plate 2 can be adjusted by the adjustment mechanism, the extension plate 6 on the upper part of the guide plate 2 can be oriented towards the lower die-cutting roller 31. Furthermore, because the extension plate 6 on the upper part of the guide plate 2 can slide upwards under the push of the elastic element, the top of the extension plate 6 can abut against the roller surface of the lower die-cutting roller 31 in the rotary die-cutting machine 3. In this state, the extension plate 6 compensates for the height difference between the top of the guide plate 2 and the lower die-cutting roller 31, eliminating the waste discharge dead angle at the top of the guide plate 2 and preventing waste debris from accumulating on the top of the guide plate 2. This allows the waste debris to slide smoothly along the extension plate 6 and the guide plate 2 into the collection hopper 1, improving the waste debris collection effect and contributing to environmental protection.

[0048] The process of adjusting the tilt angle of the guide vane 2 by the adjustment mechanism is as follows:

[0049] S1. Tighten the nut 84 outward to increase the distance between the nut 84 and the clamping plate 82. At this time, the screw 83 can move within the arc-shaped hole 13.

[0050] S2. If the screw 83 is moved upward along the arc-shaped hole 13, the screw 83 drives the adjusting rod 81 to move upward. The adjusting rod 81 drives the guide plate 2 to rotate counterclockwise around the pin 22, making the inclination of the guide plate 2 gentler. If the screw 83 is moved downward along the arc-shaped hole 13, the screw 83 drives the adjusting rod 81 to move downward. The adjusting rod 81 drives the guide plate 2 to rotate clockwise around the pin 22, making the inclination of the guide plate 2 steeper. When the top of the upper extension plate 6 of the guide plate 2 abuts against the roller surface of the lower die-cutting roller 31 in the rotary die-cutting machine 3, the screw 83 stops moving.

[0051] S3. Tighten nut 84 in the reverse direction to reduce the distance between nut 84 and clamping plate 82 until nut 84 and clamping plate 82 clamp the side of collecting hopper 1. Use the friction between nut 84 and side of collecting hopper 1 and the friction between clamping plate 82 and side of collecting hopper 1 to fix screw 83 in the current position in arc hole 13, so that guide plate 2 is stable at the current tilt angle.

[0052] Furthermore, in the rotary die-cutting machine 3, the distance between the upper and lower die-cutting rollers 31 needs to be adjusted according to the thickness of the packaging paper, causing the height of the lower die-cutting roller 31 to change. In this embodiment, because the extension plate 6 can move upward relative to the guide plate 2 under the push of the elastic element, even if the height of the lower die-cutting roller 31 changes, the extension plate 6 can still abut against the roller surface of the lower die-cutting roller 31 to maintain contact. This allows the extension plate 6 to still compensate for the height difference between the top of the guide plate 2 and the lower die-cutting roller 31, preventing waste from accumulating on the top of the guide plate 2 and ensuring the collection effect and environmental protection effect of waste.

[0053] By adjusting the tilt angle of the guide plate 2 using the adjustment mechanism, the efficiency of die-cutting waste falling from the guide plate 2 into the collection hopper 1 can be adjusted. For example, the steeper the tilt of the guide plate 2, the faster the waste slides over the guide plate 2, resulting in a faster speed at which the waste enters the collection hopper 1, thus improving the waste collection efficiency. This enhances the flexibility of the collection device in this embodiment.

[0054] In addition, since the bottom of the guide plate 2 is rotatably connected to the top of the collection hopper 1, and the adjustment mechanism can adjust the tilt angle of the guide plate 2, the guide plate 2 does not need to be fixed to the body of the rotary die-cutting machine 3 by bolts. Thus, when the rotary die-cutting machine 3 is replaced, the guide plate 2 can be reused, and there is no need to configure a separate guide plate 2 for each rotary die-cutting machine 3, which improves the adaptability of the collection device in this embodiment.

[0055] Furthermore, in this embodiment, the adjustment mechanism has a simple and reliable structure. Because the screw 83 in the adjustment mechanism is located within the arc-shaped hole 13 on the side of the collecting hopper 1, the worker can operate from the side of the collecting hopper 1 when swinging the screw 83 within the arc-shaped hole 13. The side space of the collecting hopper 1 is ample, making operation convenient. The handle 85 provides a gripping position for the worker, further enhancing ease of use.

[0056] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
