Description

Technical Field

[0001] This invention relates to a four-sided tear film device. Background Technology

[0002] In some products, adhesive stickers are attached to the four edges (e.g., ...). Figure 7 As shown in the top view, the surface of the adhesive tape 10 has a protective top film 101. One end of the top film 101 is a film head 1011, which is used to peel the top film 101 off the product. When a person pinches the film head 1011 and pulls it upward, the top film 101 is peeled off along the other end of the adhesive tape 10. The top film 101 is usually removed manually; however, if it can be removed mechanically, production efficiency can be improved. Summary of the Invention

[0003] The purpose of this invention is to provide a four-sided film-tearing device that solves the problem of how to remove the top film more efficiently.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0005] This invention provides a four-sided film-tearing device, which includes a first slide plate and a second slide plate disposed on a warp adjustment guide rail extending in a first direction. Both the first and second slide plates are provided with two weft adjustment guide rails extending in a second direction, distributed along the length direction on the first and second slide plates. A weft adjustment slider is slidably disposed on each of the four weft adjustment guide rails. A film-pulling cylinder is connected to each weft adjustment slider. Each film-pulling cylinder has a film-clamping cylinder at its drive end. The film-clamping cylinder has grippers for clamping the film head. The film-clamping cylinder is used to clamp the top film head on the four-sided adhesive tape of the product and lifts the film head upwards under the drive of the film-pulling cylinder. The four-sided film-tearing device also includes a peeling rod and a peeling motor that moves the peeling rod to peel the top film starting from the film head.

[0006] Preferably, it also includes a product placement platform, on which a negative pressure adsorption mechanism is provided.

[0007] Preferably, it also includes a top membrane suction mechanism for collecting the top membrane.

[0008] Preferably, the film-peeling rod is connected to the film-peeling slider, the film-peeling slider is disposed on the film-peeling guide rail, the film-peeling slider is provided with a threaded hole and a film-peeling screw is engaged in the threaded hole, and the film-peeling screw can rotate under the drive of the film-peeling motor.

[0009] Furthermore, photoelectric sensors are provided at both ends of the film peeling guide rail, and baffles corresponding to the photoelectric sensors are provided on the film peeling slider.

[0010] Preferably, there are two radial adjustment guides, which are arranged in parallel, and the two ends of the first and second sliding plates are respectively slidably disposed on the radial adjustment guides.

[0011] Furthermore, the first and second slide plates are respectively equipped with a radial adjustment slider, and a radial adjustment screw is engaged with the radial adjustment slider. The radial adjustment screw is driven by a radial adjustment motor to adjust the position of the first and second slide plates on the radial adjustment guide rail.

[0012] Preferably, the driving direction of the film-pulling cylinder is at a certain angle to the vertical direction.

[0013] Preferably, the distal ends of all lead screws are housed within bearings.

[0014] Preferably, each of the four latitudinal adjustment guide rails is provided with a photoelectric sensor at both ends, and also includes a baffle that cooperates with the photoelectric sensor, the baffle being disposed on the latitudinal adjustment slider.

[0015] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art:

[0016] The four-sided film-peeling device of the present invention adjusts the positions of four weft adjustment sliders to match the product size by sliding the first and second sliding plates on the warp adjustment guide rail and by sliding the weft adjustment slider on the weft adjustment guide rail. After the positions are adjusted, the film-pulling cylinder on the weft adjustment slider descends, moving the film-clamping cylinder towards the film head. Then, the film head is clamped by the grippers on the film-clamping cylinder. After clamping, the film-pulling cylinder rises to achieve the film-lifting effect. Then, the film-peeling rod moves along the extension direction of the top film to peel the top film off the product, while the adhesive strip remains on the product. This improves production efficiency. Attached Figure Description

[0057] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0058] like Figure 5 The four-sided film-tearing device shown includes a mounting platform 1, various components mounted on the mounting platform 1, and a product placement platform 2. Figure 6 Product 13 is placed on product placement table 2, and product 13 has adhesive stickers on its four edges. For example... Figure 7 As shown in the top view diagram, the adhesive 10 has a top film 101, one end of which has a film head 1011 for lifting the film, and then the top film 101 is peeled off from the product.

[0059] like Figure 1 The components mounted on the mounting platform 1 are used to remove the top film from the four sides of the product. The mounting platform 1 has a hollow center, with a warp adjustment rail 3 on each side of the hollow center. The warp adjustment rails 3 on both sides are parallel, and a first sliding plate 4 and a second sliding plate 5 are slidably mounted on the warp adjustment rails 3. The two ends of the first sliding plate 4 and the second sliding plate 5 are slidably mounted on the two warp adjustment rails 3, which provides high stability. Two weft adjustment sliders 7 are mounted on both the first sliding plate 4 and the second sliding plate 5.

[0060] like Figure 8 and Figure 9 Two weft adjustment guide rails 6 are provided on both the first slide plate 4 and the second slide plate 5, and the two weft adjustment guide rails 6 are distributed along the length of the first slide plate 4 or the second slide plate 5. A weft adjustment slider 7 is slidably provided on each weft adjustment guide rail 6, and a weft adjustment screw 24 is engaged in the weft adjustment slider 7. The weft adjustment screw 24 is driven to rotate by the weft adjustment motor 23, thereby adjusting the position of the weft adjustment slider 7 on the weft adjustment guide rail 6.

[0061] like Figure 4 Both the first slide plate 4 and the second slide plate 5 are equipped with a radial adjustment slider 19, and a radial adjustment motor 21 is set on the platform of the mounting base 1. A radial adjustment lead screw 20 is installed on the drive end of the radial adjustment motor 21, and the radial adjustment lead screw 20 engages with the radial adjustment slider 19. The second slide plate 5 is driven to slide on the radial adjustment guide rail 3 by the radial adjustment motor 21. Similarly, on the other side, the first slide plate 4 is driven to slide on the radial adjustment guide rail 3 by another radial adjustment motor 21.

[0062] like Figure 2 A film-pulling cylinder 8 is connected to the weft-adjusting slider 7, and a film-clamping cylinder 9 is connected to the drive end of the film-pulling cylinder 8. The drive end of the film-clamping cylinder 9 has a clamping jaw 91, which is used to clamp the film head 1011 (see...). Figure 7 The driving direction of the membrane-pulling cylinder 8 is at a certain angle to the vertical direction, thereby allowing the gripper 91 to tilt and lift the membrane head 1011. In this example, refer to... Figure 1 The clamping cylinders 9 are arranged in a circumferential direction, and the grippers 91 of adjacent clamping cylinders 9 are placed at 90° to facilitate simultaneous tearing. Figure 7 The four-sided top membrane 101 is shown.

[0063] like Figure 9 Each weft adjustment guide rail 6 is equipped with a photoelectric sensor 17 at both ends, and a baffle 18 is provided on the weft adjustment slider 7. The baffle 18 corresponds to the photoelectric sensor 17, so that the position of the weft adjustment slider 7 can be determined and the stroke of the weft adjustment slider 7 can be controlled.

[0064] like Figure 10 The diagram shown is a bottom view, and as shown in the image. Figure 11 As shown Figure 10 The enlarged view at point E shows four peeling guide rails 15 installed below the mounting table 1, corresponding to the four sides of the product. Peeling sliders 14 are slidably mounted on the peeling guide rails 15. Each peeling slider 14 has a threaded hole into which a peeling screw 16 engages. The peeling screw 16 is driven to rotate by a peeling motor 12, which in turn drives the peeling slider 14, thereby moving the peeling rod 11 connected to the peeling slider 14. (See diagram below.) Figure 12 The peeling rod 11 is inserted between the film head 1011 and the product 13, and the top film 101 is peeled off starting from the film head 1011, thereby completely removing the top film 101, while the adhesive remains on the surface of the product 13.

[0065] Product 13 was placed Figure 6 On the product placement platform 2 shown, a negative pressure adsorption mechanism (not shown) is also provided below the product 13. The negative pressure adsorption mechanism adsorbs the product 13 downwards, so that the product 13 will not shift during operation.

[0066] In this example, a top film suction mechanism (not shown) is also provided at the edge of product 13 to suction the top film 101 that has been torn off.

[0067] like Figure 3 Photoelectric sensors 17 are also provided at both ends of the film peeling guide rail 15, and baffles 18 corresponding to the photoelectric sensors 17 are provided on the film peeling slider 14. This can monitor whether the film peeling slider 14 has reached the two ends, so as to stop the film peeling motor 12 in time.

[0068] In this example, one end of all the lead screws (film stripping lead screw 16, warp adjustment lead screw 20, weft adjustment lead screw 24) is connected to the corresponding motor drive end, and the other end is disposed in the bearing 22 to improve the smoothness of the lead screw rotation.

[0069] In summary, the workflow in this example is as follows: Figure 5 and Figure 6 Place product 13 on product placement table 2; Figure 1 Adjust the positions of the four lateral adjusting sliders 7 on the mounting platform 1 according to the product shape; start the film pulling cylinder 8, driving the film clamping cylinder 9 to move the film head 1011 on the product surface to the predetermined position; the grippers 91 on the film clamping cylinder 9 clamp the film head 1011; the film pulling cylinder 8 lifts the film clamping cylinder 9 diagonally upward, thereby lifting the film head 1011; as... Figure 12The film peeling motor 12 drives the film peeling rod 11 to insert between the film head 1011 and the product 13. The top film 101 is completely peeled off by the movement of the film peeling rod 11. The top film 101 is then sucked up and collected by the top film suction mechanism (not shown). The whole process is smooth and efficient, thereby improving production efficiency.

[0070] The above embodiments are only for illustrating the technical concept and features of the present invention. Their purpose is to enable those skilled in the art to understand the content of the present invention and implement it accordingly. They should not be used to limit the scope of protection of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
