TECHNICAL FIELD

[0001] The present application relates to the field of waste cleaning device, especially to a die cutting machine discharge port waste cleaning device. BACKGROUND

[0002] The film roll often needs to be punched in actual application, but the die cutting equipment has a short board in waste treatment: the corner material generated by punching cannot be collected in order, which causes the waste to be easily wrinkled and deformed, directly affecting the reuse value of subsequent small-size products. The current operation mode of relying on manual waste regularity not only has low efficiency, but also causes unstable waste flatness due to human operation differences, further restricting the high-value utilization of waste.

[0003] Therefore, it is necessary to provide a new die cutting machine discharge port waste cleaning device to solve the above technical problems. SUMMARY

[0004] To solve the above technical problems, the present application provides a die cutting machine discharge port waste cleaning device.

[0006] The driving device comprises a guide rail, a second spring and a Z-shaped plate, the guide rail is fixed on the mounting plate, and the driving block is slidably connected to the guide rail, the second spring is sleeved outside the guide rail, and the two ends of the second spring are connected with the end of the guide rail and the driving block respectively, the Z-shaped plate is fixed on the fixed plate, the first inclined surface and the first vertical surface are arranged on the Z-shaped plate, the second inclined surface matched with the first inclined surface and the second vertical surface matched with the first vertical surface are arranged on the driving block.

[0007] The first valve and the air inlet pipe are arranged on the Z-shaped pipe, and the second valve is arranged on the air inlet pipe.

[0008] The first valve and the second valve each comprise a valve piece and a rotating shaft, and the rotating shafts of the first valve and the second valve are respectively connected with the Z-shaped pipe and the air inlet pipe.

[0009] The end of the rotating shaft of the first valve is fixed with a first gear, the top of the connecting plate is fixed with a first rack, and the first rack is matched with the first gear.

[0010] The end of the rotating shaft of the second valve is fixed with a second gear. The top of the connecting plate is fixed with a second rack, and the second rack is matched with the second gear.

[0011] The body is respectively provided with a film releasing device and a film winding device on both sides, the film winding device is provided with a waste film collecting device between the body, and the waste film collecting device is arranged opposite to the film suction cylinder.

[0012] The air outlet is provided with a one-way valve.

[0013] The waste film collecting device comprises a base, the top of the base is symmetrically provided with arc-shaped plates, a waste film accommodating cavity is arranged between the two arc-shaped plates, a supporting spring is arranged between the top of the base and the two arc-shaped plates, the top of the supporting spring is provided with a supporting plate, and the stiffness coefficient of the spring is in linear relationship with the thickness of the waste film.

[0014] The coiled material in the roll is released by the film releasing device, the coiled material passes through the cutting plane, and the upper cutting die on the body cuts the coiled material, and the waste material after cutting is still in the coiled material,

[0015] The coiled material is wound by the film winding device, and the coiled material is in a straight state between the film winding device and the film releasing device.

The connecting plate continues to move downward a certain distance, separating the waste film from the web. The second gear meshes with the second rack, opening the second valve. Gas enters the film suction cylinder through the intake pipe and Z-shaped tube. The suction force generated by the suction hole decreases, and the waste film falls under its own gravity onto the waste film collection device. As the ram cylinder drives the fixed plate and connecting plate upward, the first and second valves close again. The second spring forces the piston back into its original position, and the gas in the piston cylinder is discharged through the outlet.

DETAILED DESCRIPTION

[0027] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application is further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application and do not limit the present application.

[0028] The specific implementation of the present application is described in detail below in combination with specific examples.

[0029] Please refer to Figures 1 to 6 The film cutting machine discharge port waste cleaning device provided by the embodiment of the present application comprises a body 1. A mounting plate 3 is fixedly installed on the top of the body 1 through a support rod 2. A punch cylinder 4 is fixedly arranged at the top center position of the mounting plate 3. The output end of the punch cylinder 4 penetrates through the mounting plate 3 and is connected with a fixed plate 6 below. An upper punching die is fixedly installed at the bottom of the fixed plate 6. Correspondingly, a punching plane 8 for cooperating with the upper punching die to perform punching operation is arranged at the top of the body 1.

[0030] A connecting plate 9 is fixedly connected to one side of the fixed plate 6. A film suction cylinder 10 for sucking waste film is embedded and fixed at the bottom of the connecting plate 9. A plurality of air suction holes are arranged at the bottom of the film suction cylinder 10 to facilitate the adsorption of waste film material generated after punching. A piston cylinder 12 is also fixedly installed at the top of the mounting plate 3. An air inlet 13 and an air outlet 14 are arranged at one side of the piston cylinder, and the piston cylinder is in communication with the film suction cylinder 10 through a Z-shaped pipe 16 to realize the transmission of airflow.

[0031] A piston 17 is installed inside the piston cylinder 12, one end of the piston is connected with a first spring 18, the other end of the first spring is connected to a connecting rod 19, the end of the connecting rod 19 away from the spring is connected to a driving block 20. In order to control the movement of the piston, a set of driving devices 21 is arranged on the mounting plate 3, which is composed of a guide rail 22, a second spring 23 and a Z-shaped plate 24. Among them, the guide rail 22 is fixed on the mounting plate 3, the driving block 20 can slide along the guide rail; the second spring 23 is sleeved outside the guide rail, and the two ends are connected with the end of the guide rail and the driving block 20 respectively; and the Z-shaped plate 24 is fixed on the fixed plate 6 and has a first inclined surface 25 and a first vertical surface 26, which are matched with a second inclined surface 27 and a second vertical surface 28 on the driving block 20, for guiding the movement of the driving block.

[0032] The Z-shaped pipe 16 is provided with a first valve 29 and an air inlet pipe 30, and the air inlet pipe is provided with a second valve 31. The two valves each include a valve plate and a rotating shaft 33, and are rotatably connected with the Z-shaped pipe or the air inlet pipe through the respective rotating shafts. The end of the rotating shaft of the first valve 29 is fixed with a first gear 34, which is engaged with a first rack 35 on the top of the connecting plate 9; similarly, the end of the rotating shaft of the second valve 31 is fixed with a second gear 36, which is engaged with a second rack 37 on the top of the connecting plate 9.

[0033] In addition, the machine body 1 is provided with a film placing device 38 and a film winding device 39 on both sides respectively, and a waste film collecting device 40 is arranged between the film winding device 39 and the machine body, which is opposite to the film suction cylinder 10. A one-way valve 41 is installed in the air outlet 14 to ensure that the gas can only be discharged outward from the piston cylinder.

[0034] The waste film collecting device 40 is composed of the base 5, the top of which is symmetrically provided with two circular arc plates 11, and a waste film containing cavity 32 is formed between the two circular arc plates. A supporting spring 7 is arranged on the top of the base between the two circular arc plates, the top end of which is connected with a supporting plate 15, and the stiffness coefficient of the spring is designed to be linear according to the thickness of the waste film, so as to adapt to the collection requirements of waste films with different thicknesses.

[0035] During operation, the coiled material is placed out through the film placing device 38, passes through the punching plane 8, and is punched by the upper punching die. At this time, the waste material is still attached to the coiled material. Then, the coiled material is wound by the film winding device 39, so that the coiled material is kept in a taut state between the film placing device and the winding device.

[0036] When the stamping cylinder 4 drives the fixed plate 6 and the connecting plate 9 to move downward, in the initial stage, the first valve 29 and the second valve 31 are both in the closed state. As the Z-shaped plate 24 moves downward together, the first inclined surface 25 thereon comes into contact with the second inclined surface 27 on the driving block 20, pushing the driving block to slide along the guide rail 22, while compressing the second spring 23. At this time, the air inlet cannot be inhaled, and the piston 17 can only move slightly, causing the first spring 18 to be stretched.

[0037] As the connecting plate 9 continues to move down, the first gear 34 first engages with the first rack 35, opening the first valve 29, while the second valve 31 is still in the closed state. At this time, the film suction cylinder 10 just contacts the waste film, the first vertical surface 26 of the Z-shaped plate contacts the second vertical surface 28 of the driving block, so that the driving block stops sliding. At this time, the suction hole, the Z-shaped pipeline 16 and the piston cylinder 12 form a communication path, and under the action of the first spring 18, the waste film is adsorbed by the suction force of the film suction cylinder.

[0038] After the first gear and the first rack are engaged for a period of time, the connecting plate continues to move down, and the second gear 36 engages with the second rack 37, opening the second valve 31. Air enters the film suction cylinder 10 through the air inlet pipe 30 and the Z-shaped pipeline 16, and the suction force at the suction hole is weakened. The waste film falls into the waste film collecting device 40 below due to its own gravity.

[0039] When the punch cylinder 4 drives the fixed plate 6 and the connecting plate 9 to move upward, the first valve 29 and the second valve 31 are closed again. Under the elastic force of the second spring 23, the driving block is reset, and then drives the piston 17 to return to the original position, and the gas in the piston cylinder 12 is discharged through the air outlet 14.

[0040] The whole waste cleaning process is highly automated, compact in structure, can effectively improve the working efficiency of the die cutting machine, reduce manual intervention, and improve the production safety.

[0041] Working principle:

[0042] I. Cylinder down phase (waste cleaning execution)

[0043] Step 1: Initial valve closing and energy storage

[0044] The punch cylinder 4 drives the output end to move down → the fixed plate 6 and the connecting plate 9 move down synchronously.

[0045] Driving device 21 action:

[0046] Z-shaped plate 24 moves down → first inclined surface 25 presses second inclined surface 27 of driving block 20.

[0047] Driving block 20 slides along guide rail 22 → compresses second spring 23.

[0048] Connecting rod 19 pulls piston 17 → first spring 18 is stretched to store energy.

[0049] Valve state:

[0050] First valve 29 is closed (valve piece closes Z-shaped pipeline 16).

[0051] Second valve 31 is closed (valve piece closes air inlet pipe 30).

[0052] Key effect: piston cylinder (12) is sealed, piston is only slightly moved.

[0053] Step 2: First valve opening and suction

[0054] Connecting plate 9 moves down a certain distance:

[0055] First rack 35 engages first gear 34 → first valve 29 rotating shaft 33 rotates → opening Z-shaped pipe 16 passage.

[0056] Synchronous action:

[0057] Suction film cylinder 10 contacts waste film.

[0058] Z-shaped plate first vertical surface 26 and driving block second vertical surface 28 fit → driving block 20 stops sliding.

[0059] Negative pressure suction:

[0060] First spring 18 retracts → piston 17 pulls back.

[0061] Negative pressure in piston cylinder 12 → air flow through air inlet 13 → Z-shaped pipe 16 → suction film cylinder 10 suction hole → suction waste film.

[0062] Step 3: Waste film separation

[0063] Connecting plate 9 continues to move down:

[0064] First rack 35 disengages first gear 34 → first valve 29 closes.

[0065] Suction film cylinder 10 pulls down the waste film → waste film and roll forced separation.

[0066] Step 4: Second valve opening and release

[0067] Connecting plate 9 moves down the end stroke:

[0068] Second rack 37 engages second gear 36 → second valve 31 rotating shaft 33 rotates → opening air inlet pipe 30 passage.

[0069] Positive pressure release:

[0070] External air → air inlet pipe 30 → Z-shaped pipe 16 → surge into suction film cylinder 10.

[0071] Negative pressure destruction → waste film gravity falls → falls into waste film containing cavity 32 of waste film collecting device 40.

[0072] II. Cylinder up phase (system reset)

[0073] Step 1: Valve closing

[0074] Punch cylinder 4 pulls output end up:

[0075] First rack 35 disengages first pinion 34 → First valve 29 closes (valve flap gravity falls back).

[0076] Second rack 37 disengages second pinion 36 → Second valve 31 closes (valve flap gravity falls back).

[0077] Step 2: Piston reset exhaust

[0078] Drive device 21 resets:

[0079] Second spring 23 releases stored energy → Pushes drive block 20 back along guide rail 22.

[0080] Connecting rod 19 pushes piston 17 back.

[0081] Exhaust action:

[0082] Gas in piston cylinder 12 is under pressure → Unidirectionally discharged through outlet 14 one-way valve 41 (prevents backflow).

[0083] Step 3: Overall reset

[0084] Z-shaped plate 24 moves up with fixed plate 6 → Disengages drive block 20.

[0085] All components return to initial position.

[0086] III. Detailed explanation of independent system functions

[0087] 1. First valve 29 system

[0088] Component functions

[0089] First pinion 34 converts vertical displacement of first rack 35 into rotational motion.

[0090] Shaft 33 drives valve flap to open and close Z-shaped pipe 16.

[0091] The timing of the action is only opened in the middle of the descent, connecting the film suction cylinder 10 and the piston cylinder 12 to generate negative pressure.

[0092] Opening and closing control is triggered by the connecting plate 9 downward stroke: open when contacting the waste film, and close before separating the waste film.

[0093] 2. Second valve 31 system

[0094] Component functions

[0095] Second pinion 36 converts vertical displacement of second rack 37 into rotational motion.

[0096] Shaft 33 drives valve flap to open and close intake pipe 30.

[0097] The action timing is only when the lower end is opened, and air is injected into the film suction cylinder 10 to release the negative pressure.

[0098] The opening and closing control is triggered by the lower end of the connecting plate 9: opened after the waste film is separated, and closed when the air cylinder moves up.

[0099] 3. Waste film collecting device 40

[0100] Adaptive structure:

[0101] The stiffness coefficient of the supporting spring 7 is pre-set according to the thickness of the waste film → the supporting plate 15 linearly moves down with the waste film accumulation.

[0102] The arc-shaped plate 11 guides the waste film to accurately fall into the containing cavity 32.

[0103] The circuit and control involved in the present application are all prior art, and will not be described in detail here.

[0104] The above is only an embodiment of the present application, and does not limit the patent scope of the present application, and any equivalent structure or equivalent process transformation using the content of the present application specification and drawings, or direct or indirect application in other related technical fields, are also included in the patent protection scope of the present application.
