Description

Technical Field

[0001] The invention belongs to the technical field of packaging, and in particular relates to a device for punching exhaust holes in an aluminum foil bag and a punching method thereof. Background Art

[0002] For the aluminum foil bag packaging of game cards, the arrangement of the exhaust holes can prevent the bag from expanding and bursting when it is heat-sealed. The existing exhaust hole punching device usually adopts a needle wheel, including a punching disk, on which a punching needle is inserted. The number of the punching needles on the punching disk is reasonably set according to the size of the packaging bag and the subsequent packaging effect. However, the punching needles on the punching disk are not vertical when they contact the aluminum foil bag. When the exhaust needles pierce the aluminum foil bag, they will also apply a tangential force to the aluminum foil bag and the punching disk, causing the aluminum foil bag to be pulled, and the shape and size of the generated exhaust holes are easy to change. The circumference of the punching needles is arranged on the punching disk and extends along the radial direction of the punching disk. The distance between adjacent punching needles gradually decreases from one side of the needle head to the other side of the punching disk. When the aluminum foil bag moves relatively from the tip of the punching needle to the punching disk, the aluminum foil bag between adjacent punching needles will be relatively wrinkled, affecting the final packaging quality. Summary of the invention

[0013] The invention also includes a punching method of the above-mentioned aluminum foil bag exhaust hole punching device, comprising the following steps:

[0014] S1: placing the aluminum foil roll to be processed on the unwinding roller, pulling out the aluminum foil and laying it through the guide rollers on the supporting plate in sequence;

[0015] S2: The direction and position of the aluminum foil film on the adjusting roller are judged by the photoelectric sensor in the positioning device. If one side of the aluminum foil film is not aligned with the alignment line, the cylinder in the positioning device drives the adjusting roller to move until one side of the aluminum foil film is aligned with the alignment line during the conveying process;

[0016] S3: The punching device punches holes, and the driving component reciprocates to push the puncher to cooperate with the receiving seat to punch holes. When punching holes, the ejection component in the puncher can push the blanks generated by the punching into the blanking collection component in the receiving seat, and the fixed plate no longer closes the vent during the punching. The gas is ejected through the vent through the punching channel, which can blow away the debris attached to the punching end of the punch generated during the punching, and can also blow away the debris in the punching groove;

[0017] S4: Check whether the punching quality meets the requirements through the detection device;

[0018] S5: Enter the automatic packaging device for packaging.

[0019] The positioning device detects and adjusts the position of the aluminum foil film on the adjusting roller in real time, and the detection device detects the exhaust holes on the aluminum foil film in real time.

[0020] In this technical solution,

[0021] The beneficial effects of the present invention are:

[0022] 1. The device uses a puncher connected to the driving component, and the puncher includes a shell connected to the driving component. A punch is slidably arranged on the side of the shell away from the driving component. This structure ensures that the punching needle can remain vertical when piercing the aluminum foil bag, avoiding the phenomenon of pulling the aluminum foil film due to the tilt of the punching needle during traditional needle wheel punching, thereby improving the stability of the shape and size of the exhaust hole; and avoids the situation that when punching with a traditional needle wheel, the circumference of the punching needle is arranged on the punching disc and extends in the radial direction of the punching disc. The spacing between adjacent punching needles from one side of the needle head to the other side of the punching disc gradually decreases. When the aluminum foil bag moves relatively from the tip of the punching needle to the punching disc, relative wrinkles are likely to occur, affecting the final packaging quality;

[0023] 2. The aluminum foil film is pressed against the upper end of the receiving block. When punching, the punching end of the punch cooperates with the punching groove to punch. When punching, one side of the punch slides upward in the sliding channel, and the push rod extends out of the punch to push the blanks produced by the punching into the negative pressure channel through the blanking port on the baffle. The radial length of the blanking port is smaller than the radial length of the blanks. When the blanks are pushed into the negative pressure channel through the blanking port, they will be deformed and squeezed, which can prevent the blanks from getting stuck or stacked at the blanking port, thereby ensuring the continuity and stability of the punching process.

[0024] 3. When punching, the punch slides upward in the sliding channel, driving the guide slide column to move upward in the first chamber, pushing the closed block to move upward. At this time, the fixed plate no longer closes the vent, and the gas is ejected through the vent through the punch push-out channel, which can blow away the debris attached to the punching end of the punch generated during the punching, and at the same time, the debris in the punching groove can be blown away, ensuring the quality of the exhaust holes generated in the continuous punching;

[0025] 4. The positioning device can monitor and correct the deviation of the aluminum foil in real time during the transmission process, avoiding production interruptions or product quality problems caused by deviation. BRIEF DESCRIPTION OF THE DRAWINGS

[0050] Second embodiment:

[0051] This embodiment provides a punching device 6 for exhaust holes of an aluminum foil bag. In addition to the technical solutions of the above embodiment, it also has the following technical features.

[0052] As Figure 3-5 shown, the first chamber 14 is connected to an intake pipe 30, the other side of the intake pipe 30 is connected to an external air source, a sealing collar is slidably arranged in the first chamber 14, the side wall of the sealing collar 31 abuts against the inner wall of the first chamber 14, a ventilation port 32 is arranged in the middle of the sealing collar, and the fixing plate 22 can close the ventilation port 32 when it abuts against the ventilation port 32. A return spring 33 is arranged between the sealing collar and the top wall of the first chamber 14. A push block 34 abuts against the bottom of the sealing collar 31, and the push block 34 is fixedly connected to a guide slide bar 19 extending into the first chamber 14.

[0053] As Figure 3-5 shown, the sealing collar 31 includes an annular sealing block 35, the sealing block 35 abuts against the inner wall of the first chamber 14, a support boss 36 is arranged in the middle of the sealing block 35, a ventilation port 32 is arranged in the middle of the support boss 36, and slide holes 37 are arranged around the ventilation port 32 corresponding to the fixed column 23.

[0054] During punching, the punch 11 slides upward in the sliding channel 15, driving the guide slide bar 19 to move upward in the first chamber 14, pushing the sealing block 35 to move upward. At this time, the fixing plate 22 no longer closes the ventilation port 32, and the gas sprays out through the ventilation port 32 and the ejection channel 16 of the punch 11, which can blow away the debris adhering to the punching end of the punch 11 during punching, and at the same time can blow away the debris in the punching groove 25, ensuring the quality of the exhaust holes generated during continuous punching.

[0055] Third Embodiment:

[0056] This embodiment provides a punching device 6 for exhaust holes of an aluminum foil bag. In addition to the technical solutions of the above embodiment, it also has the following technical features.

[0057] As Figure 1 , Figure 6 , Figure 7 shown, the positioning device 5 includes a mounting plate 38 fixedly connected to the support plate member 2. The mounting plate 38 has a "C" shape with an opening downward. An adjusting roller 45 is arranged between the two side plates at the bottom side of the mounting plate 38. One side of the adjusting roller 45 is movably connected to the side plate, and the other side is connected to an adjusting member. It also includes a photoelectric sensor 48 for detecting the position of the aluminum foil film 4 passing through the adjusting roller 45.

[0058] As Figure 6 and Figure 7As shown, the adjusting member is a first cylinder 39, and an adjusting shaft rod 40 fixedly arranged at the output end of the first cylinder 39 and one end of an adjusting roller 45 is hinged, and one end of the adjusting shaft rod 40 is slidingly arranged in an adjusting groove 47 opened on a side plate of one side of the mounting plate 38. The first cylinder 39 is hinged to a fixed seat 41 on the mounting plate 38, and an adjusting roller 45 is provided with a connecting ball 42 at one end away from the adjusting shaft rod 40. The connecting ball 42 is rollingly arranged in a movable groove 44 in a mounting block 43, and the mounting block 43 is connected to a side plate of one side of the mounting plate 38.

[0059] like Figure 8 As shown, Figure 8 It is a top view. When the aluminum foil film 4 deviates to the right during the transmission process, the photoelectric sensor 48 transmits the received information to the external control unit, and the external control unit controls the first cylinder 39 to work. The output end of the first cylinder 39 extends outward, driving the connecting shaft of the adjusting roller 45 to move downward in the vertically arranged adjusting groove 47, and the aluminum foil film 4 will deviate to the left. When the aluminum foil film 4 and the neat line 46 on the adjusting roller 45 are aligned, the first cylinder 39 stops working. When the aluminum foil film 4 deviates to the left during the transmission process, the first cylinder 39 performs the opposite operation mentioned above. When the aluminum foil film 4 deviates during the transmission process, the positioning device 5 can monitor and correct the deviation problem of the aluminum foil film 4 in real time during the transmission process, thereby avoiding production interruption or product quality problems caused by the deviation.

[0060] The positioning device 5 and the detection device 7 in the present application can be replaced by positioning components and detection components in the prior art, as long as they can complete the corresponding positioning and detection functions.

[0061] The invention also includes a punching method of the above-mentioned aluminum foil bag exhaust hole punching device 6, comprising the following steps:

[0062] S1: placing a roll of aluminum foil film 4 to be processed on the unwinding roller 3, pulling out the aluminum foil film 4 and sequentially passing it through the guide rollers on the supporting plate 2 for laying;

[0063] S2: The direction and position of the aluminum foil film 4 on the adjusting roller 45 are judged by the photoelectric sensor 48 in the positioning device 5. If one side of the aluminum foil film 4 is not aligned with the alignment line 46, the cylinder in the positioning device 5 drives the adjusting roller 45 to move until one side of the aluminum foil film 4 is aligned with the alignment line 46 during the conveying process;

[0064] S3: The punching device 6 punches holes, and the driving component reciprocates to push the punch 9 to cooperate with the receiving seat 12 to punch holes. When punching holes, the ejection component 13 in the punch 9 can push the blanks generated by punching into the blank collection component in the receiving seat 12, and the fixed plate 22 no longer closes the vent 32 during punching. The gas is ejected through the vent 32 through the push-out channel 16 of the punch 11, which can blow away the debris attached to the punching end of the punch 11 generated during punching, and can also blow away the debris in the punching groove 25;

[0065] S4: Detect whether the punching quality meets the requirements through the detection device 7;

[0066] S5: Enter the automatic packaging device 8 for packaging.

[0067] The positioning device 5 detects and adjusts the position of the aluminum foil film 4 on the adjusting roller 45 in real time, and the detection device 7 detects the exhaust holes on the aluminum foil film 4 in real time.

[0068] The embodiments of the present application are described above in conjunction with the accompanying drawings.
