[0023] The following describes a device for removing film on products according to an embodiment of the first aspect of the utility model with reference to the accompanying drawings.

[0024] like Figure 1 As shown, the product upper film removal device includes: a cutting mechanism 10, a positioning and conveying mechanism 20, an upper film removal mechanism 30 and a driving mechanism 40.

[0025] The cutting mechanism 10 is used to cut the packaging bag of the product into two parts, the upper film and the lower film. In specific operation, the cutting mechanism 10 can cut the packaging bag of the product with a complete packaging bag that has not been cut, and can also cut the packaging bag of one side, two sides or three sides of the product that have not been cut. In other words, the cutting mechanism 10 can cut the upper film alone as needed, or cooperate with other cutting mechanisms to cut and remove the packaging bag of the product.

[0026] In one specific embodiment, the cutting mechanism 10 is provided with two groups, which are used to cut the packaging bags that are not cut on both sides, so as to divide the packaging bags into upper film and lower film. According to the needs, the two groups of cutting mechanisms 10 can be arranged in parallel or perpendicular to each other. As shown in the figure, the two groups of cutting mechanisms 10 arranged in parallel are arranged on both sides of the product, and are driven by the driving mechanism 40 to move to the cutting position for cutting after the product is in place. Preferably, the two groups of cutting mechanisms 10 can be arranged and moved in a direction perpendicular to the product transmission direction, so that the two sides of the product perpendicular to the transmission direction can be cut. After the cutting is completed, the driving mechanism 40 drives the product to return to the initial position to avoid interference with the transmission of the product. Specifically, the cutting mechanism 10 includes a cutter 11 and a cutter drive 12 that drives the cutter to cut the packaging bag. The cutter drive 12 can adopt a linear module, a servo motor or a linear cylinder.

[0027] Before cutting the packaging bag of the product, it is necessary to position the product with the packaging bag to the cutting position, and at the same time, it is necessary to limit the product during the cutting process to prevent the cutter 11 from pulling the product during the cutting process, causing the product to shift, causing product damage or inadequate cutting. By setting the positioning and conveying mechanism 20, the packaging bag product to be cut can be limited to a preset area before the cutting mechanism 10 is activated. Specifically, the positioning and conveying mechanism 20 includes a first positioning module 21 arranged at the front end of the packaging bag product to be cut, a second positioning module 22 arranged on one side of the product, a limiting plate 23 arranged on the other side of the product, and a pushing module 24 arranged at the rear end of the product for cooperating with the first positioning module 21, the second positioning module 22 and the limiting plate 23 to position the product, and the pushing module 24 is also configured to push the product to the next station. Among them, the front end of the packaging bag product to be cut refers to the end where the product is located in the forward direction, close to the next station, and the rear end of the packaging bag product to be cut refers to the end opposite to the forward direction of the product, close to the top station. The first positioning module 21 is located at the front end and can push and position the product backwards, and the pushing module 24 is located at the rear end and can push and position the product forwards. One side of the product refers to the end perpendicular to the product transmission direction, and the limit plate 24 located on one side is set in a fixed position as a reference position. The second positioning module 22 located on the other side can move in a direction perpendicular to the transmission direction, so as to push the product to the limit plate 23. Therefore, the product is pushed by the first positioning module 21, the second positioning module 22 and the pushing module 24, and then cooperates with the limit plate 23 to achieve the positioning of the product. When cutting, the product can also be clamped to avoid the position of the product from shifting.

[0028] Preferably, both the first positioning module 21 and the second positioning module 22 include: a driving cylinder 211 and a limit push rod 212 arranged at the movable end of the driving cylinder. After the upper film is removed, the product needs to continue to move forward to the next workstation, so the first positioning module 21 located at the front end is preferably arranged above the product, controlled by a liftable mechanism, and needs to be limited to descend and perform related operations, and then rise to avoid when the product moves forward. Before the product is loaded, it needs to be transferred from the previous workstation, so the pushing module 24 located at the rear end also needs to be driven to rise or fall by a mechanism that can control the lifting. Further, the pushing module 24 includes: a pushing platform 241, a lifting drive 242 that drives the pushing platform 241 to rise or fall, and a pushing drive 243 that drives the pushing platform 241 forward or backward.

[0029] The upper film removal mechanism 30 is used to pick up the upper film of the product and transfer it to the recovery area. The upper film removal mechanism 30 adopts an adsorption component.

[0030] The driving mechanism 40 can be provided in two groups, driving the cutting mechanism 10 and the upper film removing mechanism 30 to move respectively, or a single group can be provided, and the cutting mechanism 10 and the upper film removing mechanism 30 are integrated at the movable end of the driving mechanism 10. When the driving mechanism 40 is provided in one group, the cutting mechanism 10 and the upper film removing mechanism 30 are simultaneously driven to the top of the product, the cutting mechanism 10 first performs the cutting action, after the cutting is completed, the cutting mechanism 10 is reset, and the driving mechanism 40 drives the cutting mechanism 10 and the upper film removing mechanism 30 to further descend, so that the upper film removing mechanism 30 can smoothly pick up the upper film, after the upper film is picked up, the driving mechanism 40 drives the cutting mechanism 10 and the upper film removing mechanism 30 to move to the recovery area, and the upper film removing mechanism 30 puts down the upper film, completing the upper film removal operation of the product.

[0031] The driving mechanism 40 includes a lifting assembly 41, a translation assembly 42 disposed at a movable end of the lifting assembly 41, and a mounting plate 43 disposed at a movable end of the translation assembly 42. The cutting mechanism 10 and / or the upper film removing mechanism 30 are disposed on the mounting plate 43.

[0032] The present application also provides a product packaging bag cutting production line, comprising the product upper film removing device as described above.
