Description

Technical Field

[0001] The utility model particularly relates to an automatic induction feeding mechanism for a sticker die-cutting machine. Background Art

[0002] During the toy production process, both the toy itself and the shell usually need to be provided with sticker patterns to meet the needs of use or improve the aesthetics. Therefore, the demand for stickers is relatively large. However, during mass production, the stickers are produced in long strips and need to be cut as needed to make them into the designed size to meet the needs of use. Although the existing sticker die-cutting machines can feed the sticker tape in sequence at the feed end and complete the cutting, the tension of the sticker tape during the conveying process cannot be controlled, which can easily cause the sticker tape to be too long or too short, affecting the conveying. If the sticker tape is too long, it is easy to fold, and if it is too short, it is easy to stretch the sticker tape, resulting in damage to the sticker, which will affect the quality of the die-cutting process. Summary of the Invention

[0003] In view of the deficiencies in the prior art, the purpose of the present invention is to provide an automatic induction feeding mechanism for a sticker die-cutting machine.

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0019] Example

[0020] An automatic induction feeding mechanism for a sticker die-cutting machine includes a feeding bellows 1, a flat tube 3 installed at the bottom of the feeding bellows 1 and connected to the center of the bottom of the feeding bellows 1, a suction device 4 fixedly installed on one side of the outside of the feeding bellows 1 and connected to the flat tube 3, and also includes two baffles 2 movably installed inside the feeding bellows 1 and adjustable according to the width of the sticker strip. The space between the two baffles 2 forms a negative pressure cavity connected to the flat tube 3.

[0021] The feeding bellows 1 includes a base 11, C-shaped channel steels 12 welded on both sides of the bottom of the base 11 for embedding flat tubes 3, long box plates 13 symmetrically fixed on the top of the base 11, short box plates 14 symmetrically fixed on the top of the base 11 and fixed to the two long box plates 13 on the sides by screws, lower guide columns 15 passing through the bottoms of the two baffles 2 and fixed to the short box plates 14 at both ends, two upper guide columns 16 passing through the upper ends of the two baffles 2 and fixed to the short box plates 14 at both ends, two pressure columns 17 passing through the upper ends of the two baffles 2 and fixed to the short box plates 14 at both ends, and an infrared sensor 18 fixedly installed in the middle of the lower guide column 15 and located between the two baffles 2. Specifically, the pressure column 17 is located above the two upper guide columns 16, so that the two baffles 2 can be fixed by clamping the pressure columns 17.

[0022] In this embodiment, an air outlet 111 is formed in the center of the base 11 .

[0023] In this embodiment, the infrared sensor 18 is an industrial infrared sensor that can sense the sticker tape entering the interior of the feeding bellows 1 , thereby cooperating with the start-up of the suction device 4 to form a negative pressure cavity in the space between the two baffles 2 .

[0024] The baffle 2 includes a baffle body 21 and locking components 22 fixedly mounted on both sides of the upper end of the baffle body 21 .

[0025] A lower guide column sleeve 211 is installed in the middle of the lower end of the baffle body 21, and an upper guide column sleeve 212 is installed on both sides of the upper end of the baffle body 21. Through holes 213 located above the upper guide column sleeve 212 are also opened on both sides of the upper end of the baffle body 21, which can specifically be used to assemble the lower guide column 15 and the upper guide column 16.

[0026] The locking assembly 22 includes a fixing block 221 with a screw hole fixed to the baffle body 21 by bolts, a threaded push rod 222 screwed into the fixing block 221, and a handle 223 fixedly installed above the threaded push rod 222. Specifically, the fixing block 221 is located above the through hole 213, and the pressure column 17 passes through the through hole 213. After the baffle body 21 is movably adjusted to a fixed position, the threaded push rod 222 is pressed against the pressure column 17 by rotating the handle 223, thereby achieving fixed installation of the baffle body 21.

[0027] The flat tube 3 includes a flat tube body 31, a circular pipe connection port 32 located above one end of the flat tube body 31, a rectangular suction port 33 located above the other end of the flat tube body 31, and a debris blocking mesh plate 34 screwed to the rectangular suction port 33. Specifically, the flat tube body 31 can be embedded within the C-shaped channel steels 12 on both sides below the base 11 for fixation, while the circular pipe connection port 32 connects to the suction device 4. The rectangular suction port 33, with the debris blocking mesh plate 34 fixed thereto, is aligned with the air outlet 111, thereby drawing air between the two baffles 2 and creating a negative pressure that allows the adhesive tape to be drawn in. This facilitates adaptive tensioning during the adhesive tape application process, preventing the adhesive tape from being too long and affecting transportation. It also helps prevent the adhesive tape from being too long and folding, which could affect the die-cutting process.

[0028] The suction device 4 includes a bracket 41 fixedly mounted to the feeding bellows 1 by screws, a suction fan 42 fixedly mounted on the bracket 41, a corrugated hose 43 installed at the suction end of the suction fan 42 and connected to the flat tube 3, and a guide wind hood 44 fixedly mounted at the output end of the suction fan 42. Specifically, the corrugated hose 43 is connected to the circular pipe port 32.

[0029] The above embodiments of the present invention are not intended to limit the scope of protection of the present invention, and the implementation methods of the present invention are not limited thereto. All other modifications, replacements or changes made to the above structure of the present invention based on the above contents of the present invention, in accordance with common technical knowledge and customary means in this field, without departing from the above basic technical ideas of the present invention, should fall within the scope of protection of the present invention.
