Description

Technical Field

[0001] This utility model relates to the field of packaging processing machinery technology, specifically to a re-adhesive slitting and winding machine. Background Technology

[0002] A re-adhesive slitting, cross-cutting, and rewinding machine is a specialized piece of equipment used for processing roll materials such as tapes, films, and paper. It is commonly used in industries such as packaging, printing, and electronics manufacturing. This machine integrates multiple functions, completing the re-adhesive, slitting, cross-cutting, and final rewinding processes for materials such as tapes.

[0003] Based on the above, the inventors have discovered the following problems: When the current cross-cutting winding machine needs to replace the winding roller, it needs to cross-cut the material strip. After cross-cutting, the end of the material strip will fall to the guide roller, and it is not convenient to wrap the end of the material strip around the outside of the new winding roller, which is inconvenient to use.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a re-adhesive slitting and winding machine in order to achieve a more practical purpose. Utility Model Content

[0005] The purpose of this utility model is to provide a re-adhesive slitting and cross-cutting winding machine to solve the problems mentioned in the background art. A re-adhesive slitting and cross-cutting winding machine includes a machine body. A re-adhesive assembly, a slitting assembly, and a cross-cutting and winding assembly are provided inside the machine body. The slitting assembly is disposed between the re-adhesive assembly and the cross-cutting and winding assembly. The cross-cutting and winding assembly includes a cross-cutting plate. Fixed plates are provided at the top and bottom of the cross-cutting plate. A telescopic rod is fixedly installed on the side of the fixed plate facing the cross-cutting plate. A cutting plate is fixedly installed at the output end of the telescopic rod. A cross blade is fixedly installed on the cutting plate facing the cross-cutting plate. A blade groove is provided on both the top and bottom surfaces of the cross-cutting plate. A fixing strip is provided on the side of the cutting plate where the cross blade is fixedly installed. A limiting groove is provided on the inner side of one end of the machine body. A pull rod is fixedly installed on the side of the fixing strip away from the slitting assembly. Damping sliders are fixedly installed at both ends of the fixing strip. Guide sliders are fixedly installed at both ends of the cutting plate. Both the damping sliders and the guide sliders are slidably connected to the limiting groove. By adopting the above technical solution, the slitting assembly is set between the adhesive bonding assembly and the cross-cutting and winding assembly, which facilitates the adhesive bonding assembly to coat and bond the material strip. After being coated and bonded, the material strip is cut into strips by the slitting assembly. The strip then enters the cross-cutting and winding assembly for cross-cutting. A cross blade is fixedly installed on the cutting plate facing the cross-cutting plate, and the top and bottom surfaces of the cross-cutting plate are provided with knife grooves. This allows the telescopic rod to move the cutting plate up and down, so that the cross blade and the knife groove cooperate to cross-cut the strip after slitting. The damping slider and the guide slider are slidably connected to the limiting slide groove, which guides the up and down movement of the fixing strip and the cutting plate. When the cutting plate moves towards the cross-cutting plate to cross-cut the material strip, it pushes the fixing strip towards the cross-cutting plate. There is a certain friction between the damping slider and the limiting slide groove, which allows the fixing strip to firmly clamp and fix the cut end of the hopper onto the cross-cutting plate, making it convenient for the operator to wind the end of the material strip onto the new winding roller.

[0006] Furthermore, the cross-cutting plate is provided with two fifth guide rollers on the side facing the slitting assembly, and the fifth guide rollers are rotatably connected to the machine body.

The fifth guide rollers are rotatably connected to the machine body, which facilitates the guidance of the slitting strip, so that the strip passes between the cross-cutting plate and the cutting blade and is wound on the take-up roller.

[0008] Furthermore, two take-up rollers are provided on the side of the cross-cutting plate away from the slitting assembly, and the fifth guide roller is rotatably connected to the machine body. By adopting the above technical solution, the take-up rollers facilitate the winding of the strip that has undergone adhesive coating and slitting.

[0009] Furthermore, the adhesive assembly includes an adhesive hopper, a coating roller is rotatably connected to the top side of the adhesive hopper, and a scraper is provided on the bottom side of the coating roller.

[0010] By adopting the above technical solution, a glue-applying roller is rotatably connected to the top side of the glue hopper, and a scraper is provided on the bottom side of the glue-applying roller. This facilitates the storage of glue liquid in the glue hopper, makes it easy for the glue-applying roller to apply the glue liquid onto the material belt, and the scraper can scrape off excess glue from the surface of the glue-applying roller to avoid excessive glue application.

[0011] Furthermore, a glue injection port is provided in the middle of the other side of the top of the glue hopper, and liquid level sensors are provided on both sides of the glue injection port.

[0012] By adopting the above technical solution, a glue injection port is provided in the middle of the other side of the top of the glue hopper, and liquid level sensors are provided on both sides of the glue injection port. This facilitates the connection between the external pipeline and the glue injection port, and makes it convenient to inject glue into the glue hopper when the liquid level sensor detects that the amount of glue inside the glue hopper is insufficient.

[0013] Furthermore, a first guide roller is provided at the bottom of the glue hopper, and a second guide roller is provided at the top of the glue hopper. Both the first guide roller and the second guide roller are rotatably connected to the machine body.

[0014] By adopting the above technical solution, the first guide roller and the second guide roller are both rotatably connected to the machine body, which facilitates the first guide roller and the second guide roller to guide the material belt, and makes it convenient for the coating roller to coat the adhesive on one side of the material belt.

[0015] Furthermore, a fourth guide roller is provided at the top of the second guide roller, and a third guide roller is provided on the side of the fourth guide roller away from the slitting assembly. Both the third guide roller and the fourth guide roller are rotatably connected to the machine body.

[0016] By adopting the above technical solution, the third and fourth guide rollers are rotatably connected to the machine body, which facilitates the guidance of another material strip and makes it easier for the material strip and the adhesive-coated material strip to enter between the two composite pressure rollers for extrusion molding.

[0017] Furthermore, the second guide roller is provided with two composite pressure rollers on the side facing the slitting assembly, and the composite pressure rollers are rotatably connected to the machine body.

[0018] By adopting the above technical solution, the composite pressure roller is rotatably connected to the machine body, which facilitates the two composite pressure rollers to composite and form the material strip and the material strip coated with adhesive, thus forming a material strip with better performance.

[0019] Furthermore, the slitting assembly includes a first slitting roller and a second slitting roller, both of which are rotatably connected to the machine body, and a cutting sleeve is fitted on the outer side of the first slitting roller and the second slitting roller.

[0020] By adopting the above technical solution, a cutting sleeve is provided on the outer side of the first slitting roller and the second slitting roller, so that the rotation of the cutting sleeve can drive the material strip after it has been coated with adhesive to move.

[0021] Furthermore, a blade ring is fixedly installed on the outside of the cutting sleeve located outside the first slitting roller, and an annular groove is formed on the outside of the cutting sleeve located outside the second slitting roller.

[0022] By adopting the above technical solution, the design of the blade ring and annular groove facilitates the cutting and slitting of the coated strip.

This allows the telescopic rod to move the cutting plate up and down, enabling the cross blade and grooves to cooperate in cross-cutting the slit strip. Damping sliders and guide sliders further enhance the cutting efficiency. All components are slidably connected to the limiting slide groove, which facilitates the vertical movement of the fixing strip and the cutting plate by the limiting slide groove. When the cutting plate moves towards the cross-cutting plate to cut the material strip, it pushes the fixing strip towards the cross-cutting plate. There is a certain friction between the damping slider and the limiting slide groove, which enables the fixing strip to firmly clamp and fix the cut end of the hopper onto the cross-cutting plate. This makes it convenient for workers to wind the end of the material strip onto the new take-up roller. This utility model can clamp and fix the cut end of the hopper onto the cross-cutting plate, making it convenient for workers to wind the end of the material strip onto the new take-up roller.

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-5This utility model provides a technical solution: a re-adhesive slitting and cross-cutting winding machine, including a machine body 101. The machine body 101 has a re-adhesive assembly 102, a slitting assembly 103, and a cross-cutting and winding assembly 104 disposed inside the machine body 101. The slitting assembly 103 is positioned between the re-adhesive assembly 102 and the cross-cutting and winding assembly 104, facilitating the re-adhesive assembly 102 to apply adhesive to the strip. After re-adhesion, the strip is cut into slits by the slitting assembly 103, and then enters the cross-cutting and winding assembly 104 for winding and cross-cutting. 4 includes a cross-cutting plate 10401, with fixing plates 10405 at its top and bottom. A telescopic rod 10406 ​​is fixedly installed on the side of the fixing plate 10405 facing the cross-cutting plate 10401. A cutting plate 10407 is fixedly installed at the output end of the telescopic rod 10406. A cross blade 10408 is fixedly installed on the cutting plate 10407 facing the cross-cutting plate 10401. Both the top and bottom surfaces of the cross-cutting plate 10401 have cutting grooves 10402. The cross blade 10408 is fixedly installed on the cutting plate 10407 facing the cross-cutting plate 10401, and the cutting grooves 10402 on both the top and bottom surfaces of the cross-cutting plate 10401 facilitate… The telescopic rod 10406 ​​drives the cutter plate 10407 to move up and down, causing the cross blade 10408 and the blade groove 10402 to cooperate in cutting the slit strip. The cutter plate 10407 is fixedly installed with the cross blade 10408 and has a fixing strip 10410 on one side. The inner side of one end of the machine body 101 is provided with a limit slide groove. A pull rod 10412 is fixedly installed on the side of the fixing strip 10410 away from the slitting assembly 103. Damping sliders 10411 are fixedly installed at both ends of the fixing strip 10410. Guide sliders 10409 are fixedly installed at both ends of the cutter plate 10407. Both the damping slider 10411 and the guide slider 10409 are fixedly installed with the limit. The limiting slide is slidably connected to the limiting slide through the damping slider 10411 and the guide slider 10409. This allows the limiting slide to guide the up and down movement of the fixing bar 10410 and the cutter plate 10407. When the cutter plate 10407 moves toward the cross-cutting plate 10401 to cut the material strip, it pushes the fixing bar 10410 toward the cross-cutting plate 10401. There is a certain friction between the damping slider 10411 and the limiting slide, which allows the fixing bar 10410 to firmly clamp and fix the cut end of the hopper onto the cross-cutting plate 10401, making it convenient for workers to wrap the end of the material strip onto the new take-up roller 10404.

[0031] The cross-cutting plate 10401 is provided with two fifth guide rollers 10403 on the side facing the slitting assembly 103. The fifth guide rollers 10403 are rotatably connected to the machine body 101. The presence of two fifth guide rollers 10403 on the side facing the slitting assembly 103 and the rotatable connection between the fifth guide rollers 10403 and the machine body 101 facilitates the guidance of the slitting strip, allowing the strip to pass between the cross-cutting plate 10401 and the cutter plate 10407 and be wound around the take-up roller 10404.

[0032] The cross-cutting plate 10401 has two take-up rollers 10404 on the side away from the slitting assembly 103. The fifth guide roller 10403 is rotatably connected to the machine body 101. The take-up rollers 10404 facilitate the winding of the strip after coating and slitting. The coating assembly 102 includes a glue hopper 10201. A coating roller 10202 is rotatably connected to the top side of the glue hopper 10201. A scraper 10203 is provided on the bottom side of the coating roller 10202. The glue hopper 10201 stores the glue, and the coating roller 10202 applies the glue to the strip. The scraper 10203 scrapes off excess glue from the surface of the coating roller 10202, preventing over-coating. The glue hopper 10201 has a glue injection port 10204 located in the middle of the other side of the top. Liquid level sensors 10205 are located on both sides of the glue injection port 10204. The glue injection port 10204 is located in the middle of the other side of the top of the glue hopper 10201, and liquid level sensors 10205 are located on both sides of the glue injection port 10204. This facilitates the connection between the external pipeline and the glue injection port 10204, so that when the liquid level sensor 10205 detects that the amount of glue inside the glue hopper 10201 is insufficient, glue can be injected into the glue hopper 10201.

[0033] The glue hopper 10201 has a first guide roller 10206 at the bottom and a second guide roller 10207 at the top. Both the first guide roller 10206 and the second guide roller 10207 are rotatably connected to the machine body 101. The rotatable connection of the first guide roller 10206 and the second guide roller 10207 to the machine body 101 facilitates the guidance of the material belt by the first guide roller 10206 and the second guide roller 10207, making it convenient for the glue coating roller 10202 to coat the glue liquid on one side of the material belt.

[0034] The second guide roller 10207 has a fourth guide roller 10209 at its top, and a third guide roller 10208 is provided on the side of the fourth guide roller 10209 away from the slitting assembly 103. Both the third guide roller 10208 and the fourth guide roller 10209 are rotatably connected to the machine body 101. The rotatable connection of the third guide roller 10208 and the fourth guide roller 10209 to the machine body 101 facilitates the guidance of another strip, making it easier for the strip and the strip coated with adhesive to enter between the two composite pressure rollers 10210 for extrusion molding.

[0035] Among them, the second guide roller 10207 is provided with two composite pressure rollers 10210 on the side facing the slitting assembly 103. The composite pressure rollers 10210 are rotatably connected to the machine body 101. The rotatable connection between the composite pressure rollers 10210 and the machine body 101 facilitates the two composite pressure rollers 10210 to composite and form the material strip and the material strip coated with adhesive, thereby forming a material strip with better performance.

[0036] The slitting assembly 103 includes a first slitting roller 10301 and a second slitting roller 10302. Both the first slitting roller 10301 and the second slitting roller 10302 are rotatably connected to the machine body 101. A cutting sleeve 10303 is sleeved on the outer side of the first slitting roller 10301 and the second slitting roller 10302. The cutting sleeve 10303 is sleeved on the outer side of the first slitting roller 10301 and the second slitting roller 10302 so that the rotation of the cutting sleeve 10303 can drive the material strip after being coated with glue to move.

[0037] A blade ring 10304 is fixedly installed on the outside of the cutting sleeve 10303 located outside the first slitting roller 10301, and an annular groove 10305 is opened on the outside of the cutting sleeve 10303 located outside the second slitting roller 10302. The blade ring 10304 and the annular groove 10305 facilitate the cutting and slitting of the coated strip.

[0038] Specifically, the working principle of this type of adhesive-coated slitting and winding machine is as follows: During use, the first guide roller 10206 and the second guide roller 10207 are rotatably connected to the machine body 101, facilitating the guidance of the material strip by the first guide roller 10206 and the second guide roller 10207. This allows the coating roller 10202 to apply adhesive to one side of the material strip. The coating roller 10202 is rotatably connected to the top side of the glue hopper 10201. A scraper 10203 is located on the bottom side of the coating roller 10202, facilitating the storage of adhesive in the glue hopper 10201 and the application of adhesive by the coating roller 10202 onto the material strip. The scraper 10203 scrapes away excess adhesive from the surface of the coating roller 10202, preventing over-coating. The adhesive is then transferred through the glue hopper 10201... A glue injection port 10204 is located in the middle of the other side of the top. Liquid level sensors 10205 are located on both sides of the glue injection port 10204, facilitating connection between external pipes and the glue injection port 10204. This allows for the injection of glue into the glue hopper 10201 when the liquid level sensors 10205 detect insufficient glue. The third guide roller 10208 and the fourth guide roller 10209 are rotatably connected to the machine body 101, facilitating the guidance of another material strip. This allows the material strip and the glue-coated material strip to enter between two composite pressure rollers 10210 for extrusion molding. The composite pressure rollers 10210 are rotatably connected to the machine body 101, facilitating the composite molding of the material strip and the glue-coated material strip by the two composite pressure rollers 10210. The process involves shaping a higher-performance strip. A cutting sleeve 10303 is fitted around the outer sides of the first and second slitting rollers 10301 and 10302, allowing the rotation of the cutting sleeve 10303 to move the coated strip. A blade ring 10304 and an annular groove 10305 facilitate the cutting and slitting of the coated strip. Two fifth guide rollers 10403 are located on the side of the cross-cutting plate 10401 facing the slitting assembly 103. These fifth guide rollers 10403 are rotatably connected to the machine body 101, guiding the slitting strip through the cross-cutting plate 10401 and the cutter plate 10407, winding it around the take-up roller 10404. The cutter plate 10407 then guides the strip towards the cross-cutting plate... A cross blade 10408 is fixedly installed on plate 10401, and grooves 10402 are provided on both the top and bottom surfaces of the cross-cutting plate 10401. This facilitates the movement of the telescopic rod 10406, which drives the cutting plate 10407 to move up and down. The cross blade 10408 and the grooves 10402 cooperate to cross-cut the slit strip. The damping slider 10411 and the guide slider 10409 are slidably connected to the limiting groove, which guides the up and down movement of the fixing bar 10410 and the cutting plate 10407. When the cutting plate 10407 moves towards the cross-cutting plate 10401 to cross-cut the strip, it pushes the fixing bar 10410 towards the cross-cutting plate 10401. There is a certain amount of friction between the damping slider 10411 and the limiting groove.The fixing strip 10410 securely clamps and fixes the cut hopper end to the cutting plate 10401, facilitating the worker to wind the strip end onto the new take-up roller 10404. The take-up roller 10404 facilitates the winding of the strip after re-adhesion and slitting.
