[0044] Combine the following Figure 1-Figure 4 The utility model is a packaging material film removing device, which comprises: a packaging material moving mechanism, a packaging material rotating mechanism, a cutting mechanism and a film tearing mechanism.

[0045] The packaging material moving mechanism includes: a first slide rail 101 and a support seat 102. The support seat 102 is slidably arranged on the first slide rail 101. The support seat 102 can be lifted and moved. The support seat 102 is used to support the packaging material. The packaging material rotating mechanism is located on both sides of the packaging material moving mechanism, and is used to drive the packaging material to rotate synchronously. The cutting mechanism is located above the support seat 102, and is used to cut the protective film of the packaging material located on the support seat 102. The film tearing mechanism is located on both sides of the packaging material moving mechanism, and is used to adsorb the protective film and separate the protective film from the packaging material.

[0046] Specifically, the first slide rail 101 serves as a guide component for the flow direction of the packaging material, ensuring that the packaging material is transported along the direction of the first slide rail 101. The support seat 102 is used to support the packaging material, which moves along the direction of the first slide rail 101 and has a lifting function to lift the packaging material to the film tearing position. The support seat 102 can be designed as follows according to the shape of the packaging material: Figure 3 The arc-shaped groove shown, the packaging material can be placed in the arc-shaped groove accordingly.

[0047] The packaging material rotation mechanism is used to drive the packaging material to rotate synchronously. During the rotation process, the cutting mechanism cuts the protective film on the outside of the packaging material along the circumferential direction. After the packaging material rotates for several weeks, the cut protective film is adsorbed by the film tearing mechanism and separated from the packaging material.

[0048] It is understandable that the cutting mechanism does not move during the process of cutting the protective film, but only drives the packaging material to rotate through the packaging material rotating mechanism, so that the packaging material rotates relative to the cutting mechanism, thereby cutting the protective film. After the packaging material rotates for several weeks, the protective film is cut from the middle along the circumference into two parts, and the protective film will still stick to the packaging material. The film tearing mechanism needs to be used to absorb the protective film and separate the protective film from the packaging material, thereby completing the packaging material film removal operation.

[0049] The utility model provides a packaging material film removal device, comprising: a packaging material moving mechanism, a packaging material rotating mechanism, a cutting mechanism and a film tearing mechanism; the packaging material moving mechanism comprises: a first slide rail 101 and a support seat 102, the support seat 102 is slidably arranged on the first slide rail 101, the support seat 102 can be lifted and moved, and the support seat 102 is used to support the packaging material; the packaging material rotating mechanism is located on both sides of the packaging material moving mechanism, and is used to drive the packaging material to rotate synchronously; the cutting mechanism is located above the support seat 102, and is used to cut the protective film of the packaging material located on the support seat 102; the film tearing mechanism is located on both sides of the packaging material moving mechanism, and is used to adsorb the protective film and separate the protective film from the packaging material. The utility model provides a packaging material film removing device, which can adjust the position of the packaging material through a packaging material moving mechanism and realize automatic transportation of the packaging material, and drive the packaging material to rotate synchronously through a packaging material rotating mechanism. During the rotation of the packaging material, a cutting mechanism is used to cut the protective film along the circumferential direction, and a film tearing mechanism is used to absorb the cut protective film and separate the protective film from the packaging material, thereby realizing automatic packaging material film removing operation, replacing manual film removing operation, improving work efficiency, improving safety, and reducing manpower consumption.

[0050] In one embodiment of the utility model, the packaging material film removal device further includes: a first support frame 201 and a second support frame 202 arranged on both sides of the first slide rail 101, and a third support frame 203 supported above the first support frame 201 and the second support frame 202.

In this embodiment, the horizontal movement of the support seat 102 and the packaging material is realized by the sliding cooperation between the sliding plate 103 and the first slide rail 101. The first driving unit 104 is installed on the sliding plate 103. The first driving unit 104 can use a driving component such as a motor or an electric cylinder to drive the support seat 102 to move up and down. Preferably, two first driving units 104 are arranged in front and behind to drive the support seat 102 synchronously.

The two first column heads 3011 are arranged opposite to each other, and the two first column heads 3011 are located on a side closer to each other than the second column head 3012, and the first column head 3011 has a first cutter for cutting the protective film on the center hole of the packaging material; the diameter of the first column head 3011 is less than or equal to the diameter of the center hole of the packaging material, and is used to insert into the center hole of the packaging material, and the diameter of the second column head 3012 is greater than the diameter of the center hole of the packaging material, and is used to clamp the two sides of the packaging material. Specifically, if Figure 4 As shown, the column head structure 301 is composed of a first column head 3011 with a smaller diameter at the front end and a second column head 3012 with a larger diameter at the rear end. After the column head structure 301 moves to the center hole position of the packaging material, the protective film at the center hole position is cut open by the first cutter at the front end of the first column head 3011 (not marked in the figure, the first cutter is a serrated blade arranged along the circumference of the first column head, used to cut the protective film), the first column head 3011 is inserted into the center hole, and the second column head 3012 is tightly attached to the side wall of the packaging material, thereby clamping the packaging material, and the two column head structures 301 rotate synchronously, thereby driving the synchronous rotation.

[0053] In one embodiment of the present utility model, each packaging material rotation mechanism further includes: two second drive units 302 arranged oppositely and two third drive units 303 arranged oppositely. Among them, the fixed ends of the two second drive units 302 are respectively arranged on the first support frame 201 and the second support frame 202, and the two second drive units 302 can move in the direction of approaching each other or moving away from each other; the fixed ends of the two third drive units 303 are arranged on the movable ends of the second drive units 302 in a one-to-one correspondence, and the movable ends of the two third drive units 303 are connected to the column head structure 301 in a one-to-one correspondence, and are used to drive the column head structure 301 to rotate. Specifically, two second drive units 302 are provided, which are respectively used to drive their respective column head structures 301 to approach each other or move away from each other. When the two column head structures 301 approach each other and clamp the packaging material, the column head structure 301 is driven to rotate through the third drive unit 303, thereby driving the packaging material to rotate synchronously. Preferably, the second drive unit 302 can adopt a driving component such as an electric cylinder or a cylinder, and the third drive unit 303 can adopt a driving component such as a power supply machine.

In this embodiment, the fourth drive unit 401 is arranged to drive the second cutter 402 to perform lifting movement, so that the second cutter 402 moves to the top of the packaging material to cut the protective film. Preferably, the second cutter 402 adopts a high-frequency ultrasonic knife, and the fourth drive unit 401 can adopt a driving component such as an electric cylinder.

[0055] In one embodiment of the present utility model, the cutting mechanism further includes: a pressure sensor, which is disposed on the second cutter 402. In this embodiment, the pressure value monitored by the pressure sensor is set to reflect whether the height position of the second cutter 402 is appropriate, and the second cutter 402 can be adjusted to a suitable height through the fourth driving unit 401, thereby avoiding the problem that the second cutter 402 does not contact the protective film, resulting in a cutting failure, and also avoiding the problem that the second cutter 402 is damaged due to excessive pressure.

[0056] In one embodiment of the utility model, the film tearing mechanism includes: two fifth drive units 501 arranged opposite to each other and two suction cups 502 arranged opposite to each other. Among them, the fixed ends of the two fifth drive units 501 are arranged on the third support frame 203, and the two fifth drive units 501 can move in a direction close to each other or move away from each other; the two suction cups 502 are arranged at the movable ends of the fifth drive unit 501 in a one-to-one correspondence. In this embodiment, the suction cup 502 is used to adsorb the protective film, and the suction cup 502 is driven by the fifth drive unit 501 to approach or move away from the packaging material. When the cutting mechanism has finished cutting the protective film, the fifth drive unit 501 drives the suction cup 502 to approach the position of the protective film and adsorb it. Then, the fifth drive unit 501 drives the suction cup 502 away from the protective film to separate the protective film from the packaging material. Preferably, the fifth drive unit 501 can use a driving component such as an electric cylinder.

[0057] In one embodiment of the utility model, the film tearing mechanism further includes: two pairs of roller units 503 arranged opposite to each other and two sixth drive units 504 arranged opposite to each other. Each pair of roller units 503 is composed of two rollers arranged in sequence along the height direction, and the rollers can perform rolling motion; the fixed ends of the two sixth drive units 504 are arranged on the third support frame 203, and the movable ends of the two sixth drive units 504 are connected to the roller units 503 one by one, and are used to drive the two rollers in the corresponding roller units 503 to move in a direction close to each other or in a direction away from each other. When the suction cup 502 absorbs the protective film and moves in a direction away from each other, the two rollers in each pair of roller units 503 are in a state of moving away from each other, and the suction cup 502 passes between the two rollers; when the suction cup 502 moves into position in a direction away from each other, the two rollers in each pair of roller units 503 are in a state of moving close to each other and pressing the protective film, and the rollers roll and drive the protective film to move in the direction of the suction cup 502. In this embodiment, four rollers are provided, two rollers are provided on both sides of the packaging material, and the sixth driving unit 504 drives the rollers on the same side to move closer to or farther from each other in the height direction. When the suction cup 502 absorbs the protective film and moves to both sides, the two rollers are in a state of moving away from each other, and the suction cup 502 passes between the two rollers. At this time, the suction cup 502 is on the outside of the roller, and the protective film is also between the two rollers. After that, the two rollers approach each other and clamp the protective film between them. At the same time, the rollers rotate, thereby driving the protective film to move, completely peeling the protective film from the packaging material, and then sucking and recovering it by the suction cup 502. It can be understood that since the protective film is still attached to the packaging material after being cut, the adsorption force close to the suction cup 502 may not be sufficient to completely peel the protective film from the packaging material. Therefore, the rollers provided in this embodiment can clamp the protective film and drive the protective film to be completely peeled off from the packaging material through the rotation of the rollers. It should be understood that the upper roller moves downward and the lower roller moves upward to approach each other, and vice versa, they move away from each other. A driving component such as an electric cylinder or a linear module can be used to drive the upper and lower rollers to move. When the roller clamps the protective film, the suction cup 502 can be closed, and the protective film can be peeled off only by the roller. The function of the suction cup 502 is only to adsorb and guide the protective film to the position of the roller.

[0058] In one embodiment of the utility model, the packaging material film removal device further includes: a material unloading mechanism, which is arranged downstream of the film tearing mechanism and is used to collect the torn protective film. In this embodiment, the material unloading mechanism includes a waste trough 601 and a waste basket 602, the waste trough 601 is located below the suction cup 502, and the waste basket 602 is located below the waste trough 601. The peeled protective film is unloaded and recovered in sequence through the waste trough 601 and the waste basket 602 and transported away by a trolley.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
