Description

Technical Field

[0001] This utility model relates to the field of waste removal technology for die-cutting of buffer tape, and in particular to a waste removal device for die-cutting of buffer tape on a die-cutting machine. Background Technology

[0002] Cushioning tape is a type of tape with built-in cushioning function, mostly made of EVA foam. Its core function is to absorb impact and reduce friction when packaging, fixing, or installing items. Cushioning tape has a wide range of uses, and its shape varies depending on the application. When producing cushioning tape of a specific shape, die-cutting is often used. After die-cutting, waste material also needs to be removed.

[0003] In the existing technology, when performing waste removal work on the buffer tape, the strip-shaped waste material is wound around the paper tube outside the winding shaft. After a single waste removal is completed, the operator needs to manually unfix the paper tube from the outside of the winding shaft and remove it, and then fix a new paper tube. The operation is relatively cumbersome and time-consuming, requiring a long downtime of the die-cutting machine to complete the replacement operation.

[0004] Therefore, it is necessary to invent a buffer tape die-cutting waste removal device for die-cutting machines to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a buffer tape die-cutting waste removal device for die-cutting machines. This device can secure the next waste paper tube while the previous waste paper tube is being wound. Simultaneously, after the waste paper is wound, gravity is used to quickly remove the waste paper tube, reducing the difficulty of replacement and saving manpower. This solves the problem mentioned in the background art, where after a single waste removal is completed, the operator needs to manually unsecure and remove the paper tube from the outside of the winding shaft, and then resecure a new paper tube. This operation is relatively cumbersome and time-consuming, requiring a long downtime of the die-cutting machine to complete the replacement operation.

[0006] According to one aspect of this disclosure, the following technical solution is provided: a waste removal device for buffer tape die-cutting on a die-cutting machine, comprising:

[0007] An air-blowing and guiding mechanism is used to separate finished cushioning tape from waste material;

[0008] A clamping drive mechanism, used to clamp adjacent waste paper tubes and drive them to rotate; and

[0009] The traction and collection mechanism includes a fixed plate C fixedly installed on the right side of the top of the workbench. An adjusting shaft is rotatably nested on the right side of the fixed plate C via a bearing. A manual turntable is fixedly connected to the right end of the adjusting shaft. A connecting block is fixedly sleeved on the middle of the outer side of the adjusting shaft. Four winding shafts are nested on the outer side of the connecting block via a bearing that rotates evenly. A retaining ring is fixedly sleeved on the outer side of any one of the winding shafts near the connecting block. Waste paper tubes are fixedly sleeved on the outer side of the upper winding shaft and the front winding shaft through friction.

[0010] According to at least one embodiment of the present disclosure, a buffer tape die-cutting waste removal device for a die-cutting machine includes an air blowing and guiding mechanism comprising a worktable fixedly connected to the output end of the die-cutting machine frame, and a guide frame fixedly disposed at the bottom of the worktable.

[0011] According to at least one embodiment of the present disclosure, a buffer tape die-cutting waste removal device for a die-cutting machine has two fixed plates A fixedly disposed on the top left side of the worktable, and a guide roller is rotatably nested between the two fixed plates A via a bearing.

[0012] According to at least one embodiment of the present disclosure, a buffer tape die-cutting waste removal device for a die-cutting machine is provided, wherein an adjustment frame is fixedly provided at the top center of the worktable, and two adjustment sliders are slidably sleeved on the outside of the adjustment frame. A locking bolt is threaded through the top left side of each adjustment slider in a vertical direction, and an air blowing pipe is fixedly provided through the top right end of each of the two adjustment sliders in a vertical direction. The output end of each of the two air blowing pipes is connected to an air source.

[0013] According to at least one embodiment of the present disclosure, a buffer tape die-cutting waste removal device for a die-cutting machine includes a pressing drive mechanism comprising a fixed plate B fixedly disposed on the right side of the top of the worktable. A hydraulic cylinder is fixedly disposed on the front side of the fixed plate B. The output shaft of the hydraulic cylinder extends to the back side of the fixed plate B and is fixedly connected to a U-shaped frame. Guide shafts that slide through the fixed plate B are fixedly disposed on both sides of the front side of the U-shaped frame. The guide shafts are slidably connected to the fixed plate B through linear bearings.

[0014] According to at least one embodiment of the present disclosure, a buffer tape die-cutting waste removal device for a die-cutting machine is provided, wherein a motor is fixedly disposed inside the U-shaped frame, and the output shaft of the motor extends to the back of the U-shaped frame and is fixedly connected to a pressure plate.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] This invention features a traction collection mechanism. After waste collection, the hydraulic pump station controls the hydraulic cylinder to retract its output shaft. At this time, the U-shaped frame, driven by a motor, releases the pressure plate from the adjacent waste paper tubes. Under gravity, the waste paper tubes wound with waste material rotate synchronously with the connecting block and adjusting shaft via the inner winding shaft. Subsequently, the waste paper tubes wound with waste material detach from the outside of the winding shaft and fall under gravity. The paper tubes on the outside of the upper winding shaft are then synchronously rotated to the waste collection station adjacent to the pressure plate. The hydraulic pump station then controls the hydraulic cylinder to extend its output shaft until the waste paper tubes are pressed again. In subsequent waste collection processes, another waste paper tube is sleeved and fixed on the outside of the upper winding shaft. Compared with the prior art, this invention allows the next waste paper tube to be sleeved and fixed while the previous waste paper tube is winding with waste material. At the same time, after the waste material is wound, gravity is used to quickly remove the waste paper tubes, reducing the difficulty of replacement and saving manpower. Attached Figure Description

[0029] Figure 3 This is a schematic diagram of the pressing drive mechanism 2 of a buffer tape die-cutting waste removal device for a die-cutting machine according to one embodiment of the present disclosure.

[0030] Figure 4 This is a schematic diagram of the traction collection mechanism 3 of a buffer tape die-cutting waste discharge device for a die-cutting machine according to one embodiment of the present disclosure.

[0031] like Figures 1-4 As shown, the waste removal device for buffer tape die-cutting on a die-cutting machine disclosed herein may include components such as an air blowing and guiding mechanism 1, a pressing and driving mechanism 2, and a traction and collection mechanism 3.

[0032] like Figure 2As shown in this disclosure, the air blowing and guiding mechanism 1 includes a worktable 11 fixedly connected to the output end of the die-cutting machine frame. As the basic load-bearing component of the device, it is made of 304 stainless steel with a brushed surface and anti-scratch tape. Its dimensions must match the output end of the die-cutting machine, and during installation, it must be horizontally aligned with the output end. A guide frame 12 is fixedly installed at the bottom of the worktable 11. This guide frame is made of thin steel plate bent into a U-shaped groove structure with an inclination angle of 15-20° to ensure that finished products slide down naturally without accumulating. Two fixed plates A13 are fixedly installed on the top left side. A guide roller 14 is nested between the two fixed plates A13 via a bearing. An adjustment frame 15 is fixedly installed at the top center of the worktable 11. Two adjustment sliders 16 are slidably sleeved on the outside of the adjustment frame 15. A locking bolt 17 is threaded through the top left side of each adjustment slider 16 in the vertical direction. An air blowing pipe 18 is fixedly installed through the top right end of each of the two adjustment sliders 16 in the vertical direction. The output ends of the two air blowing pipes 18 are connected to an air source.

[0033] Therefore, after the die-cut buffer tape is output from the die-cutting machine, its end is guided to pass under the guide roller 14 and the adjusting slider 16, and then the release paper at the end of the buffer tape waste is removed. Finally, the end of the buffer tape waste is attached to the outside of the waste paper tube at the waste collection station. The waste paper tube then pulls and winds the buffer tape waste. During this process, the gas from the air source is continuously sprayed onto the die-cut position on the buffer tape through the air blowing pipe 18, so that the finished buffer tape is detached from the waste and falls into the guide frame 12 and is guided out. Since the finished buffer tape has a release paper layer, it will not stick to the inside of the guide frame 12.

[0034] like Figure 3 As shown, in a preferred embodiment, the clamping drive mechanism 2 includes a fixed plate B21 fixedly disposed on the top right side of the workbench 11. A hydraulic cylinder 22 is fixedly disposed on the front of the fixed plate B21. A mini single-rod hydraulic cylinder, such as model MOB32×50, is selected. A hydraulic pump station for controlling the extension and retraction of its output shaft is connected to the hydraulic cylinder 22. The output shaft of the hydraulic cylinder 22 extends to the back of the fixed plate B21 and is fixedly connected to a U-shaped frame 23. Guide shafts 24 that slide through the fixed plate B21 are fixedly disposed on both sides of the front of the U-shaped frame 23. The guide shafts 24 are slidably connected to the fixed plate B21 through linear bearings. A motor 25 is fixedly disposed inside the U-shaped frame 23. A small servo motor is selected, and the speed is adjusted by a frequency converter. The output shaft of the motor 25 extends to the back of the U-shaped frame 23 and is fixedly connected to a clamping plate 26.

[0035] Thus, during the waste collection process, the hydraulic cylinder 22 drives the clamping plate 26 to press against the front end of the adjacent waste paper tube through the U-shaped frame 23. At this time, the corresponding retaining ring 36 cooperates with the clamping plate 26 to clamp and fix the waste paper tube. Then, the motor 25 drives the clamping plate 26 to rotate continuously. The clamping plate 26, together with the adjacent winding shaft 35 and the retaining ring 36, drives the waste paper tube with the waste end attached to it to rotate continuously, thereby making the waste paper tube continuously pull and wind the waste, so as to facilitate the continuous movement of the waste and realize the collection of the waste.

[0036] like Figure 4 As shown in this disclosure, the traction collection mechanism 3 includes a fixed plate C31, made of 304 stainless steel, which is fixedly installed on the right side of the top of the workbench 11. An adjusting shaft 32, made of 45 steel and chrome-plated for rust prevention, is nested on the right side of the fixed plate C31 via a bearing. A manual turntable 33, a circular plastic disc with anti-slip texture on the edge, is fixedly connected to the right end of the adjusting shaft 32. A connecting block 34, a cubic aluminum alloy block, is fixedly sleeved on the outer center of the adjusting shaft 32. The outer side of the connecting block 34 is evenly connected to the bearing. The rotating nested arrangement has four winding shafts 35 made of aluminum alloy, which are connected to the connecting block through rolling bearings and can rotate freely. Each winding shaft 35 has a retaining ring 36 fixedly sleeved on its outer side. The retaining ring is a circular steel ring welded to the end of the winding shaft 35 near the connecting block 34 to limit the axial displacement of the paper tube. The outer sides of the upper winding shaft 35 and the front winding shaft 35 are both sleeved with waste paper tubes. The waste paper tubes are fixed to the winding shaft 35 by friction generated by interference fit. Multiple spares can be prefabricated to avoid waiting when changing.

[0037] Therefore, after the waste material is collected, the hydraulic cylinder 22 is controlled by the hydraulic pump station to retract its output shaft. At this time, the U-shaped frame 23 drives the clamping plate 26 to release the clamping of the adjacent waste paper tubes through the motor 25. At this time, under the action of gravity, the waste paper tube with waste material wound on it drives the connecting block 34 and the adjusting shaft 32 to rotate synchronously through the winding shaft 35 on its inner side. Then, the waste paper tube with waste material wound on it directly detaches from the outside of the winding shaft 35 and falls down under the action of gravity. At this time, the paper tube outside the upper winding shaft 35 is synchronously rotated to The waste collection station adjacent to the clamping plate 26 then uses a hydraulic pump station to control the hydraulic cylinder 22 to extend its output shaft until the waste paper tube is clamped again. In the subsequent waste collection process, another waste paper tube is sleeved and fixed on the outside of the upper winding shaft 35. Compared with the existing technology, the next waste paper tube can be sleeved and fixed while the previous waste paper tube is winding the waste. At the same time, after the waste is wound, the waste paper tube can be quickly removed by gravity, reducing the difficulty of replacement and saving manpower.

[0038] It should also be noted that any content not described in detail in this specification is prior art known to those skilled in the art.

[0039] Those skilled in the art should understand that the above embodiments are merely for illustrating the present disclosure and are not intended to limit the scope of the disclosure. Those skilled in the art can make other changes or modifications based on the above disclosure, and these changes or modifications still fall within the scope of the present disclosure.
