Abstract

The invention provides a protective film stripping device for clothing hot stamping, which is technically characterized in that when a stripping mechanism is pressed down corresponding to the near edge position of a protective film, the edge of one side, near a scraper knife assembly, of a film pressing plane firstly abuts against the protective film, and a cloth pressing plane synchronously presses down to the surface of clothing; then, the film pressing block continues to be pressed downwards to rotate until the film pressing plane is flatly attached to the surface of the protective film, so that the edge of the protective film is extruded by the edge of the film pressing plane to one side of the scraper knife to be tilted, and then the scraper knife part is driven by the film clamping air cylinder to move in the X-axis direction; and after the blade point extends below the protective film with the turnup edge, the blade point and the film pressing block jointly clamp the edge of the protective film and move to strip the protective film. When the edge of the protective film is extruded and upwarped, the protective film can be reliably clamped and then stripped, so that automatic stripping of the protective film after hot stamping of clothes is realized, and the production efficiency is obviously improved; in the moving and clamping process of the scraper knife assembly, the smooth surface of the cloth pressing plane cannot damage the clothes.

Description

Technical Field

[0001] The present invention relates to the technical field of clothing hot stamping equipment, and particularly to a protective film peeling device for clothing hot stamping. Background Art

[0002] When producing clothing such as T-shirts, patterns usually need to be hot stamped on the surface; one side of these patterns is adhesively backed, and the other side is adhered with a protective film. This protective film is usually a medium-hard film, which is not only used to protect the pattern from being damaged, but also enables the pattern not to bend, fold or deform during the hot stamping process. Since the pattern hot stamped on the clothes is very thin itself, after the hot stamping is completed, the protective film almost adheres to the clothes fabric. In addition, the clothes are flexible. When peeling the protective film by mechanical means, firstly, it is difficult to clamp the edge of the protective film, and secondly, the clothes fabric is easily damaged during clamping. In actual production, manual peeling of the protective film is often adopted, which significantly limits the production efficiency. Summary of the Invention

[0003] The purpose of the present invention is to provide a protective film peeling device that can efficiently peel the protective film and will not damage the clothes.

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

[0005] A protective film peeling device for clothing hot stamping, which is used to peel the protective film after the clothing pattern is hot stamped, and the protective film is a medium-hard film. It includes a carrier plate for laying the clothes flat, a robotic arm, and a peeling mechanism arranged at the end of the robotic arm. The peeling mechanism includes:

[0006] A mounting seat, which is fixed to the end of the robotic arm and has two side plates arranged at intervals along the Y-axis;

[0007] A blade assembly, which includes a blade part, a cloth pressing block fixed to the bottom surface of the blade part, and a film clamping cylinder installed on the mounting seat for driving the blade part to move along the X-axis; the blade part has a blade edge extending along the X-axis and presenting an acute angle, the bottom surface of the cloth pressing block is a smooth cloth pressing plane, and the blade edge is higher than the cloth pressing plane and extends forward along the X-axis beyond the cloth pressing block;

[0008] A film pressing assembly is arranged relative to the scraper assembly along the X-axis direction, comprising a film pressing block with a certain width along the Y-axis direction, a rotating shaft arranged along the Y-axis direction so as to rotatably install the film pressing block between the two side plates, and a limiting assembly for limiting the rotation range of the film pressing block; the film pressing block comprises a vertical connecting portion, a first transverse portion extending from the bottom end of the connecting portion to one side of the scraper assembly, a film pressing portion extending downward from the free end of the first transverse portion, a film pressing plane arranged on the bottom surface of the film pressing portion, and a second transverse portion extending from the top end of the connecting portion to a side away from the scraper assembly, and the rotating shaft is penetrated and installed on a side of the second transverse portion close to the scraper assembly;

[0009] When the peeling mechanism moves upward away from the clothes, the film pressing block rotates and swings around the rotating shaft toward the side of the scraper assembly, so that the film pressing plane is inclined; when the peeling mechanism presses down at a position corresponding to the edge of the protective film, the edge of the film pressing plane close to the side of the scraper assembly first presses against the protective film, and the cloth pressing plane is simultaneously pressed down to the surface of the clothes, and then continues to press down to make the film pressing block rotate until the film pressing plane is flat against the surface of the protective film, so that the edge of the protective film is squeezed and tilted toward the side of the scraper by the edge of the film pressing plane, and then the scraper part moves along the X-axis direction under the drive of the film clamping cylinder, so that the blade extends under the protective film with the tilted edge and then clamps the edge of the protective film together with the film pressing block and moves to peel off the protective film.

[0010] In a preferred embodiment, the limit assembly includes a limit pin fixed between the two side plates along the Y-axis direction, and a Y-axis guide hole provided on the second transverse portion for the limit pin to pass through, wherein the guide hole is an elongated hole having a contour larger than that of the limit pin; the guide hole is located at one end of the second transverse portion away from the scraper assembly.

[0011] In a preferred embodiment, an adjusting screw is threadedly engaged with the second transverse portion at a position corresponding to the guide hole, and the adjusting screw radially penetrates into the guide hole to fine-tune the highest position or the lowest position of the film pressing block.

[0012] In a preferred embodiment, a spring is connected between the free end of the second transverse portion and the mounting seat to drive the free end of the second transverse portion to lift upward and reset.

[0013] In a preferred embodiment, the film pressing portion has a clamping inclined surface on a side opposite to the scraping blade portion, which is matched with the upper inclined surface of the blade and is used to jointly clamp the protective film.

[0014] In a preferred embodiment, the cloth pressing plane is an inclined surface slightly raised toward one side of the film pressing assembly.

[0015] A preferred solution is that the robotic arm is a three-axis robotic arm, including a first linear mechanism in the X-axis direction, a second linear mechanism in the Y-axis direction provided at the end of the first linear mechanism, and a third linear mechanism in the Z-axis direction provided at the end of the second linear mechanism. The mounting base is fixed to the end of the third linear mechanism.

[0016] A preferred solution is that the peeling device further includes a pressing mechanism provided outside the blade assembly along the X-axis direction. The pressing mechanism includes a vertically installed pressing cylinder, and a pressing strip for fixing the clothes provided at the end of the pressing cylinder and arranged along the Y-axis direction.

[0017] The beneficial effects of the above solution are as follows: when the peeling mechanism presses down at a position near the edge of the protective film, the edge of the pressing film plane near the blade assembly first abuts against the protective film, and the pressing cloth plane synchronously presses down to the surface of the clothes. Then, continue to press down to make the pressing film block rotate until the pressing film plane is flat against the surface of the protective film, so that the edge of the protective film is squeezed and lifted towards the blade side by the edge of the pressing film plane. When the edge of the protective film is squeezed and lifted, it can be reliably clamped and then peeled off, realizing the automatic peeling of the protective film after the clothes are hot stamping, and significantly improving the production efficiency; during the moving and clamping process of the blade assembly, the smooth surface of the pressing cloth plane will not damage the clothes.

[0023] The present invention will be further described below with reference to the drawings:

[0024] Refer to Figures 1 to 4 , a protective film peeling device for clothing hot stamping in this embodiment is used to peel the protective film after the clothes are hot stamped with patterns, and the protective film is a medium-hardness film, including a carrier plate for laying the clothes flat, a robotic arm 1, and a peeling mechanism 2 provided at the end of the robotic arm 1. The peeling mechanism 2 includes:

[0025] A mounting base 21, fixed to the end of the robot arm 1, and having two side plates 211 spaced apart along the Y-axis direction;

[0026] The scraper assembly 22 comprises a scraper portion 221, a cloth pressing block 222 fixed to the bottom surface of the scraper portion 221, and a film clamping cylinder 223 installed on the mounting seat 21 for driving the scraper portion 221 to move along the X-axis direction; the scraper portion 221 has a blade 2211 extending along the X-axis direction and forming an acute angle, the bottom surface of the cloth pressing block 222 is a cloth pressing plane 2221 with a smooth surface, the blade 2211 is higher than the cloth pressing plane 2221 and extends forwardly beyond the cloth pressing block 222 along the X-axis direction;

[0027] The film pressing assembly 23 is arranged relative to the scraper assembly 22 along the X-axis direction, including a film pressing block 231 with a certain width along the Y-axis direction, a rotating shaft 232 arranged along the Y-axis direction so as to rotatably install the film pressing block 231 between the two side plates 211, and a limiting assembly 233 for limiting the rotation range of the film pressing block 231; the film pressing block 231 includes a vertical connecting portion 231a, a first transverse portion 231b extending from the bottom end of the connecting portion 231a to one side of the scraper assembly 22, a film pressing portion 231c extending downward from the free end of the first transverse portion 231b, a film pressing plane 2311 arranged on the bottom surface of the film pressing portion 231c, and a second transverse portion 231d extending from the top end of the connecting portion 231a to a side away from the scraper assembly 22, and the rotating shaft 232 is penetrated and installed on the second transverse portion 231d on a side close to the scraper assembly 22;

[0028] When the peeling mechanism 2 moves upward away from the clothes, that is, in the reset state, the film pressing block 231 rotates and swings around the rotating shaft 232 toward the side of the scraper assembly 22, so that the film pressing plane 2311 is inclined; when the peeling mechanism 2 is pressed down at the position near the edge of the protective film, the edge of the film pressing plane 2311 near the side of the scraper assembly 22 first presses against the protective film, and the cloth pressing plane 2221 is simultaneously pressed down to the surface of the clothes, and then continues to press down to make the film pressing block 231 rotate until the film pressing plane 2311 is flat against the surface of the protective film, so that the edge of the protective film is squeezed and tilted toward the side of the scraper by the edge of the film pressing plane 2311, and then the scraper part 221 moves along the X-axis direction under the drive of the film clamping cylinder 223, so that the blade 2211 extends under the protective film with the tilted edge and then clamps the edge of the protective film together with the film pressing block 231 and moves to peel off the protective film.

[0029] During operation, the robotic arm 1 drives the peeling mechanism 2 to move above only the edge of the protective film, while the blade assembly 22 corresponds to above the clothing outside the edge of the protective film; the reset of the film pressing block 231 can be achieved by the center of gravity of its own side biased towards the blade assembly 22, or can also be achieved by an external force, such as a spring 25; then the robotic arm 1 drives it to press down. When the peeling mechanism 2 presses down at a position near the edge of the protective film, the edge of the film pressing plane 2311 near the blade assembly 22 abuts against the protective film, and the cloth pressing plane 2221 presses down synchronously onto the clothing surface. Subsequently, it continues to press down to make the film pressing block 231 rotate until the film pressing plane 2311 lies flat on the surface of the protective film, so that the edge of the protective film is squeezed and lifted upwards by the edge of the film pressing plane 2311 towards the blade side. After the edge of the protective film is squeezed and lifted, the clamping cylinder 223 of the film drives the blade part 221 to move closer to the film pressing assembly 23 side, and jointly clamps the edge of the protective film through the blade part 221 and the film pressing block 231. Finally, it continues to move along the X-axis direction under the drive of the robotic arm 1 to peel off the protective film. The protective film that has been squeezed and lifted can be reliably clamped and then peeled off, realizing the automatic peeling of the protective film after hot stamping, significantly improving the production efficiency; during the clamping process, the smooth surface of the cloth pressing plane 2221 will not damage the clothing.

[0030] In a preferred solution, the limiting component 233 of this embodiment includes a limiting pin 233a fixed between the two side plates 211 along the Y-axis direction, and a Y-axis direction guiding hole 233b provided on the second transverse part 231d for the limiting pin 233a to pass through. The guiding hole 233b is an oblong hole with a contour larger than the limiting pin 233a; the guiding hole 233b is located at one end of the second transverse part 231d away from the blade assembly 22. During the rotation and deflection process of the film pressing block 231, the rotation amplitude is limited by the limiting pin 233a to ensure that the film pressing plane 2311 just squeezes and lifts the protective film. In other embodiments, the limiting component 233 can also be in other forms, such as including pin shafts extending out of both sides of the second transverse part 231d along the Y-axis direction, and oblong guiding holes 233b provided on the two side plates 211 for guiding and limiting the pin shafts; or directly two sets of protrusions protruding from the side surface for limiting the up and down swing position of the second transverse part 231d, and so on.

[0031] A preferred solution is that a regulating screw 24 is in threaded fit with the second transverse part 231d of this embodiment at a position corresponding to the guiding hole 233b. The regulating screw 24 penetrates into the guiding hole 233b in the radial direction and is used to finely adjust the highest position or the lowest position of the rotation of the film pressing block 231. When the regulating screw 24 penetrates into the guiding hole 233b from top to bottom, the lowest swinging position of the bottom of the film pressing block 231 can be adjusted, and when the regulating screw 24 penetrates into the guiding hole 233b from bottom to top, the highest swinging position of the bottom of the film pressing block 231 can be adjusted.

[0032] A preferred solution is that a spring 25 is further connected between the free end of the second transverse part 231d of this embodiment and the mounting seat 21 and is used to drive the free end of the second transverse part 231d to lift and reset upward. The spring 25 can ensure the reliable reset of the film pressing block 231.

[0033] A preferred solution is that one side of the film pressing part 231c of this embodiment opposite to the shovel blade part 221 has a clamping inclined surface 2312 adapted to the upper inclined surface of the blade edge 2211 for jointly clamping the protective film. The clamping inclined surface 2312 of the film pressing part 231c and the upper inclined surface of the blade edge 2211 can jointly clamp the edge of the protective film to ensure firm and reliable clamping.

[0034] A preferred solution is that the cloth pressing plane 2221 of this embodiment is an inclined plane slightly lifted toward the film pressing assembly 23. When the cloth pressing plane 2221 is a slightly lifted inclined plane, the contact area between the film pressing plane 2311 and the clothes surface can be reduced, thereby reducing the friction on the clothes when clamping the protective film.

[0035] A preferred solution is that the robotic arm 1 of this embodiment is a three-axis robotic arm 1, including a first linear mechanism 11 in the X axis direction, a second linear mechanism 12 in the Y axis direction provided at the end of the first linear mechanism 11, and a third linear mechanism 13 in the Z axis direction provided at the end of the second linear mechanism 12. The mounting seat 21 is fixed to the end of the third linear mechanism 13.

[0036] A preferred solution is that the peeling device of this embodiment further includes a pressing mechanism 3 provided outside the shovel blade assembly 22 along the X axis direction. The pressing mechanism 3 includes a vertically installed pressing cylinder 31 and a pressing strip 32 provided at the end of the pressing cylinder 31 and arranged along the Y axis direction for fixing the clothes. The pressing strip 32 can integrally fix one end of the clothes, which is convenient for positioning the clothes and is also used to fix the clothes during the film tearing process.

[0037] The above does not impose any limitation on the technical scope of the present invention. Any modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solutions of the present invention.
