Description

Technical Field

[0001] This utility model relates to the field of die-cutting machine devices, and in particular to a waste material absorption device for a rotary die-cutting machine. Background Technology

[0002] In the production process of die-cutting machines, one or more waste removal steps are usually required to ensure that the structure of the produced products meets customer requirements. The typical waste removal method involves placing a layer of OPP material under the material to be removed. After processing by a circular cutter, the portion of the upper material to be removed is cut off as waste. The upper and lower OPP materials are then rolled separately in opposite directions. The waste material is adhered to the OPP material and peels off from the upper material, thus completing the waste removal process. During this process, some waste material may sometimes fall under the machine or into other gaps, requiring the machine operator to stop and clean it, thus affecting production efficiency.

[0003] For example, utility model CN210308111U discloses a waste cleaning device for a die-cutting machine, including an absorption box. A support column is welded to the inner bottom wall of the absorption box, and an equipment cavity is formed inside the absorption box. A clamping plate is welded to the upper outer wall of the support column. The support column is connected to the bottom outer wall of a vacuum cleaner via the clamping plate. A discharge port is provided on the front outer wall of the vacuum cleaner. This utility model, by setting up an absorption box, a vertical plate, a spring column, and a clamping plate, allows the clamping plate to be pressed down during use, causing the spring column to retract and then clamping the device onto the outer wall of the waste outlet of the die-cutting machine, thereby achieving the purpose of stably fixing the absorption box thereon. Installation is simple and easy to operate, and disassembly is also simple, facilitating the removal of the device for daily maintenance and cleaning. Simultaneously, the rubber pad on the outer wall of the clamping plate effectively protects the device body and the outer wall of the die-cutting machine, preventing direct contact between metal parts and severe scratches on the outer wall.

[0004] However, the waste absorbed by the above devices all enters the absorption box after passing through the vacuum cleaner. For large-sized waste, the vacuum cleaner is at greater risk of clogging. In order to reduce the risk of clogging, the vacuum cleaner needs to have higher power, which increases energy consumption and cost. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology, where the vacuum cleaner discharges waste into the absorption box, which poses a high risk of clogging for large-sized waste, and to provide a waste absorption device for a rotary die-cutting machine.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A waste absorption device for a rotary die-cutting machine is installed on one side of the processing shaft in the waste discharge process of the rotary die-cutting machine. It is used to connect a vacuum cleaner. The device includes a housing, a fixed cover plate, and a connecting seat. One side of the housing has an opening that matches the shape of the fixed cover plate, and the opposite side has a mounting hole that matches the connecting seat. The fixed cover plate has a suction port and is fixed to the side of the housing with the opening. The connecting seat is fixed opposite the mounting hole and is connected to the suction port of the vacuum cleaner. The vacuum cleaner communicates with the internal cavity of the housing.

[0008] Preferably, a sliding cover plate is provided on the side of the fixed cover plate away from the housing, and the sliding cover plate is slidably connected to the fixed cover plate and covers the suction port.

[0009] Preferably, the sliding cover includes a first sub-cover and a second sub-cover arranged symmetrically side by side, the first sub-cover and the second sub-cover sliding towards opposite sides of the suction port.

[0010] Preferably, the first sub-cover plate is provided with two parallel sliding limiting grooves, which are distributed parallel to the suction port. The fixed cover plate is provided with multiple limiting bolts, which are symmetrically distributed on both sides of the suction port. The limiting bolts can be slidably engaged in the sliding limiting grooves. The second sub-cover plate has the same structure as the first sub-cover plate.

[0011] Preferably, a sealing gasket is provided on the side of the sliding cover plate near the fixed cover plate.

[0012] Preferably, the connector includes a fixed section and a connecting section arranged coaxially, the diameter of the fixed section is larger than the diameter of the connecting section, the fixed section is fixed to the housing and is coaxially arranged with the mounting hole, and the connecting section is connected to the vacuum cleaner.

[0013] Preferably, a sealing gasket is provided between the fixing section and the housing.

[0014] Preferably, a connecting shaft is provided on the side of the housing away from the fixed cover plate. The connecting shaft includes a fixed arm and a rotating arm and a snap-fit ​​arm symmetrically arranged at both ends of the fixed arm. The fixed arm is fixed to the housing. One end of the rotating arm is rotatably connected to the fixed arm vertically, and the other end is connected to the snap-fit ​​arm vertically. The snap-fit ​​arm is detachably fixed to the rotary die-cutting machine.

[0015] Preferably, a sealing gasket is provided between the fixed cover plate and the housing.

[0016] Preferably, the fixing cover is fixed to the housing by screws.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] (1) This solution involves installing a detachable housing on the side of the processing shaft near the output end of the waste removal process of the rotary die-cutting machine, and connecting the housing to a vacuum cleaner. This allows for the absorption and storage of waste generated by the die-cutting machine, preventing waste from remaining in the gaps between the machines. This eliminates the need for mid-production shutdowns for cleaning, ensuring a suitable production environment, continuous production, increased efficiency, and reduced manual cleaning workload. The structure is simple, easy to assemble and disassemble, provides high-quality cleaning, and effectively improves the processing efficiency of the die-cutting machine. Furthermore, by placing the housing at the front end of the vacuum cleaner, excessive waste is prevented from entering the vacuum cleaner. Even larger waste items can be absorbed and stored inside the housing, eliminating the need for collection after passing through the vacuum cleaner. This effectively reduces the risk of vacuum cleaner clogging, improves the applicability and reliability of the device, and offers a simple structure and low cost.

[0019] (2) This solution uses a sliding cover plate on the fixed cover plate to seal the casing when it is disassembled, preventing the waste material collected inside the casing from scattering and ensuring the reliability of material suction and transfer. In addition, the use of sub-cover plates that slide to both sides makes it easy to adjust the size of the suction port according to usage requirements, thus improving the applicability of the device.

[0030] Example 1

[0031] like Figure 1 and Figure 2 As shown, this embodiment provides a waste absorption device for a rotary die-cutting machine, which is installed on one side of the processing shaft in the waste discharge process of the rotary die-cutting machine and is used to connect a vacuum cleaner. The device includes a housing 4, a fixed cover plate 1, and a connecting seat 5. One side of the housing 4 is provided with an opening that matches the shape of the fixed cover plate 1, and the opposite side is provided with a mounting hole that matches the connecting seat 5. The fixed cover plate 1 is provided with a suction port and is fixed to the side of the housing 4 with the opening. The connecting seat 5 is fixed opposite to the mounting hole and is connected to the suction port of the vacuum cleaner. The vacuum cleaner is connected to the internal cavity of the housing 4.

[0032] Working principle: The waste absorption device is installed on the side of the processing shaft near the output end of the waste discharge process of the rotary die-cutting machine. The suction port of the vacuum cleaner is installed on the connecting seat 5. When the machine is working, the vacuum cleaner is turned on. The waste material falling during the waste discharge process of the rotary die-cutting machine is drawn into the inner cavity of the housing 4 through the suction port on the fixed cover plate 3 under the action of suction, or is directly sucked into the vacuum cleaner. After the die-cutting machine finishes working, the vacuum cleaner is turned off, and the waste material in the housing 4 is collected and cleaned.

[0033] By installing a detachable housing 4 on the side of the processing shaft near the output end of the waste removal process of the rotary die-cutting machine, and connecting the housing 4 to a vacuum cleaner, the waste generated by the die-cutting machine can be absorbed and stored, preventing the waste from remaining in the gaps of the rotary die-cutting machine. This ensures that the production environment meets the requirements without having to stop the machine for cleaning during production, ensuring continuous production, improving production efficiency, and reducing the workload of subsequent manual cleaning. The structure is simple, easy to assemble and disassemble, and provides high cleaning quality while effectively improving the processing efficiency of the die-cutting machine.

[0034] In a preferred embodiment, a sliding cover plate 2 is provided on the side of the fixed cover plate 1 away from the housing 4. The sliding cover plate 2 is slidably connected to the fixed cover plate 1 and covers the suction port.

[0035] Furthermore, the sliding cover 2 includes a first sub-cover 21 and a second sub-cover 22 arranged symmetrically side by side, and the first sub-cover 21 and the second sub-cover 22 slide toward opposite sides of the suction port, respectively.

[0036] In this embodiment, the first sub-cover plate 21 is provided with two parallel sliding limiting grooves 23, which are distributed parallel to the suction port. The fixed cover plate 1 is provided with multiple limiting bolts 11, which are symmetrically distributed on both sides of the suction port. The limiting bolts 11 can be slidably engaged in the sliding limiting grooves 23. The second sub-cover plate 22 has the same structure as the first sub-cover plate 21.

[0037] By installing a sliding cover plate 2 on the fixed cover plate 1, a seal can be achieved when the housing is disassembled, preventing the waste material collected inside the housing from scattering and ensuring the reliability of material suction and transfer. Additionally, the use of sub-cover plates that slide to both sides facilitates adjustment of the suction port size according to usage requirements, expanding the applicability of the device.

[0038] Optionally, a sealing gasket is provided on the side of the sliding cover 2 near the fixed cover 1. The sealing gasket seals around the suction port, preventing waste leakage during disassembly of the housing after the sliding cover 2 is closed, thus avoiding the risk of additional cleaning and further improving the reliability of the structure.

[0039] In this embodiment, the connecting seat 5 includes a fixed section 51 and a connecting section 52 arranged coaxially. The diameter of the fixed section 51 is larger than the diameter of the connecting section 52. The fixed section 51 is fixed on the housing 4 and is coaxially arranged with the mounting hole. The connecting section 52 is connected to the vacuum cleaner.

[0040] A sealing gasket 6 is provided between the fixed section 51 and the housing 4.

[0041] In this embodiment, as Figure 3 As shown, a connecting shaft 7 is provided on the side of the housing 4 away from the fixed cover plate 1. The connecting shaft 7 includes a fixed arm 71 and a rotating arm 72 and a snap-fit ​​arm 73 symmetrically arranged at both ends of the fixed arm 71. The fixed arm 71 is fixed on the housing 4. One end of the rotating arm 72 is rotatably connected to the fixed arm 71, and the other end is connected to the snap-fit ​​arm 73. The snap-fit ​​arm 73 can be detachably fixed on the circular die-cutting machine.

[0042] In this embodiment, a sealing gasket 3 is provided between the fixed cover plate 1 and the housing 4. The fixed cover plate 1 is fixed to the housing 4 by screws.

[0043] In conjunction with the above preferred embodiments, such as Figures 1 to 3 As shown, this embodiment provides a waste absorption device for a rotary die-cutting machine, including a fixed cover plate 1, a sliding cover plate 2, a housing 4, and a connecting seat 5. The sliding cover plate has a groove and is attached to the top of the fixed cover plate. Screws on the fixed cover plate are fixed between the grooves of the sliding cover plate to limit its movement. The fixed cover plate is fixed to the top of the housing by screws. The housing has a through hole at its bottom center. The connecting seat is installed on the bottom of the housing by screws and is coaxial with the hole. The bottom of the housing is fixedly connected to the connecting shaft in the scraper device of the rotary die-cutting machine. Sealing gaskets are provided between the sliding cover plate and the fixed cover plate, between the fixed cover plate and the housing, and between the housing and the connecting seat.

[0044] Before use, install it on the connecting shaft 7, and then install the connecting shaft 7 on the circular die-cutting machine; the sliding cover plate 2 is installed above the fixed cover plate 1, the fixed cover plate 1 is fixed on the housing 4, and the lower surface of the housing 4 has a through hole; it is connected to the vacuum cleaner's air intake through the connecting seat 5. After the vacuum cleaner is started, the waste is sucked into the housing 4 or directly into the vacuum cleaner.

[0045] Specifically, remove the scraper from the scraper device of the rotary die-cutting machine, and install the waste absorption device on the connecting shaft of the scraper device. Fix the waste absorption device and the connecting shaft together at a suitable position behind the processing shaft of the rotary die-cutting machine during the waste removal process. Ensure the sliding cover above the waste absorption device is open, and insert the vacuum cleaner's suction port into the connecting seat at the bottom of the waste absorption device housing. Start the vacuum cleaner; waste falling during the waste removal process will either enter the waste absorption device housing under suction or be directly sucked into the vacuum cleaner. After the rotary die-cutting machine finishes processing, turn off the vacuum cleaner, collect and clean the waste from the housing, and then remove the waste absorption device from both the vacuum cleaner and the rotary die-cutting machine.

[0046] When a rotary die-cutting machine processes products, the waste material that falls during the waste removal process is absorbed by the waste absorption device installed on the rotary die-cutting machine. This prevents the waste material from remaining in the gaps between the machines, eliminating the need to stop the machine for cleaning during production. This ensures that the production environment meets the requirements, guarantees continuous production, improves production efficiency, and reduces the amount of manual cleaning work afterwards.

[0047] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
