Traditional adhesive strip film cutting equipment mainly completes the cutting by relative extrusion between the die and the worktable. The core structure includes a die assembly, a support platform, a drive mechanism, and a positioning system. During operation, the drive mechanism drives the die to press down, punching the adhesive strip substrate according to the preset shape, and finally obtaining the adhesive strip product of the target size.

[0003] In actual production, due to the adhesive properties of the rubber strip, the rubber strip at the blade edge tends to stick to the blade wall when the cutter cuts it. Operators need to frequently stop the machine to clean the residual adhesive on the blade, which is quite inconvenient. Utility Model Content

[0004] Therefore, it is necessary to provide a film cutting device for rubber strips that allows for easy cleaning of residual adhesive, which is a problem that operators need to stop the machine to clean up the adhesive residue when cutting rubber strips.

[0005] A film cutting device for easy cleaning of residual adhesive includes: a film cutting machine body, which consists of a film cutting machine main unit, a feeding conveyor belt, a hydraulic mechanism and blades. The feeding conveyor belt is located on one side of the film cutting machine main unit, and the hydraulic mechanism is located above the film cutting machine main unit for driving the blades to lift and lower to cut the adhesive strips. The scraping mechanism is located on the side wall of the guide rail located on the inner wall of the main body of the film cutting machine, away from the feeding conveyor belt. The scraping mechanism includes a fixed frame, which is bolted to the guide rail. The fixed frame has fixed rods at both ends of the side wall facing the blade. The fixed rods have an adaptation component inside to facilitate the scraper to adapt to the curved surface of the blade. Below the scraper, on the side wall of the fixing frame, is a collection component for collecting the residual adhesive scraped off by the scraper.

[0006] In one embodiment, the adaptation component includes a spring and a connecting rod. The spring is disposed inside the fixed rod, and the connecting rod is slidably disposed on the fixed rod toward the side wall of the scraper. The end of the connecting rod passing through the side wall of the fixed rod is connected to the end of the spring disposed inside the fixed rod, and the other end of the connecting rod is fixedly connected to the side wall of the scraper.

[0007] In one embodiment, the collection assembly includes a movable frame, the side wall of the movable frame facing away from the blade being connected to the working end of an electric telescopic rod, the bottom end of the electric telescopic rod being fixedly connected to a fixed frame, and a pull-out collection box being provided on the side wall of the movable frame facing the blade.

[0008] In one embodiment, the two ends of the side wall of the mobile frame are provided with rotating blocks by torsion springs, and the two ends of the side wall of the collection box are respectively provided with card seats, and the rotating blocks are engaged with the inside of the card seats.

[0009] In one embodiment, the inner wall of the fixed frame located on both sides of the electric telescopic rod is provided with guide grooves, and the end of the guide rod provided on the side wall of the movable frame is slidably disposed inside the guide groove.

[0010] In one embodiment, the end of the guide groove is not connected to the outer sidewall of the fixing frame.

[0011] In one embodiment, a fixed base is provided on the top surface of the movable frame near the electric telescopic rod, and an auxiliary scraper is elastically connected inside the fixed base. The end of the auxiliary scraper is slidably connected to the bottom surface of the scraper.

[0012] In one embodiment, the auxiliary scraper is provided with a downwardly inclined adhesive guide strip on the side wall facing the inside of the movable frame.

[0013] Beneficial effects 1. The above-mentioned film cutting device has a scraper on the blade side inside the film cutting machine body for scraping and cleaning the residual adhesive on the blade sidewall. The scraper inside the scraping mechanism can adapt to the blade surface. After the blade has finished cutting the adhesive strip, it is lifted under the drive of the hydraulic mechanism. During the lifting process, the scraper slides along the sidewall of the blade to scrape off the residual adhesive on the sidewall of the blade. The residual adhesive is then collected by the collection component. There is no need for the worker to stop the machine to clean the residual adhesive on the sidewall of the blade, making the operation more convenient. 2. The above-mentioned film cutting device has a fixed base on the top surface of the moving frame near the electric telescopic rod. An auxiliary scraper is elastically connected inside the fixed base by a spring. When the blade is pressed down to cut the rubber strip, the scraper is squeezed and slides along the side wall of the blade. The connecting rod on the side wall of the blade is squeezed and retracts into the fixed rod. During the retraction of the blade, the auxiliary scraper cleans the bottom end of the blade by scraping off the residual glue that has not fallen off, ensuring the cleanliness of the scraper surface and avoiding secondary contamination of the blade by the residual glue on the scraper surface.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0018] The following is combined with Figures 1-7 This invention describes a glue strip cutting device that allows for easy cleaning of residual glue.

[0019] In one embodiment, a film cutting device for easy cleaning of residual adhesive includes: a film cutting machine body 100, which consists of a film cutting machine host 101, a feeding conveyor belt 102, a hydraulic mechanism 103 and a blade 104. The feeding conveyor belt 102 is disposed on one side of the film cutting machine host 101, and the hydraulic mechanism 103 is disposed above the film cutting machine host 101 for driving the blade 104 to lift and lower to cut the adhesive strip. In this application, the model of the membrane cutting machine body 100 can be CUT-450; The adhesive scraping mechanism 200 in this application is bolted to the bracket inside the body 100 of the above-mentioned film cutting machine and is located on the side of the blade 104. It is used to scrape and clean the residual adhesive on the surface of the blade 104 after cutting, without affecting the normal use of the blade 104. like Figure 2 and Figure 3 As shown, the scraping mechanism 200 is installed on the side wall of the guide rail 105 located on the inner wall of the main body 101 of the film cutting machine, away from the feeding conveyor belt 102. The scraping mechanism 200 includes a fixing frame 201, which is bolted to the guide rail 105. The fixing frame 201 has fixing rods 202 at both ends of the side wall facing the blade 104. The fixing rods 202 have an adaptation component inside to facilitate the scraper 203 to adapt to the curved surface of the blade 104. The scraper 203 is located below the fixing frame 201 on the side wall for collecting the residual glue scraped off by the scraper 203. In this embodiment, the fixing frame 201 is bolted to the side wall of the guide rail 105 inside the film cutting machine body 100, which guides the lifting and lowering of the blade 104. The bolts facilitate installation, adjustment, disassembly, maintenance and replacement. The adaptation component inside the fixing rod 202 ensures that the scraper 203 remains in contact with the side wall of the blade 104 during the lifting and lowering process driven by the hydraulic mechanism 103, so as to scrape off and clean the residual adhesive on the side wall of the blade 104. Then, the collection component 204 below collects the residual adhesive scraped off by the scraper 203, so as to prevent the residual adhesive from falling onto the adhesive strip conveyor table below and causing pollution. like Figure 1 , Figure 3 and Figure 4 As shown, the adaptation component includes a spring 205 and a connecting rod 206. The spring 205 is respectively disposed inside the fixed rod 202. The connecting rod 206 is slidably disposed on the side wall of the fixed rod 202 toward the scraper 203. The end of the connecting rod 206 that passes through the side wall of the fixed rod 202 is connected to the end of the spring 205 disposed inside the fixed rod 202. The other end of the connecting rod 206 is fixedly connected to the side wall of the scraper 203. In this embodiment, the scraper 203 is connected to the spring 205 inside the fixed rod 202 via the connecting rod 206, so that the cutting edge of the scraper 203 is always in contact with the side wall of the blade 104. When there is unevenness or curvature change on the surface of the blade 104, the scraper 203 can slide in the fixed rod 202 via the connecting rod 206, so that the cutting edge of the scraper 203 is always in contact with the side wall of the blade 104, and the residual glue on the outer wall of the blade 104 is scraped and cleaned, avoiding the wear of the scraper 203 or the blade 104 caused by rigid contact between the scraper 203 and the blade 104. like Figure 3 , Figure 4 and Figure 5 As shown, the collection assembly 204 includes a movable frame 210. The side wall of the movable frame 210 facing away from the blade 104 is connected to the working end of the electric telescopic rod 207. The bottom end of the electric telescopic rod 207 is fixedly connected to the fixed frame 201. A pull-out collection box 211 is provided on the side wall of the movable frame 210 facing the blade 104. Rotating blocks 212 are provided at both ends of the side wall of the movable frame 210 through torsion springs. Card seats 213 are provided at both ends of the side wall of the collection box 211. The rotating blocks 212 are engaged inside the card seats 213. In this embodiment, when the blade 104 is lifted by the hydraulic mechanism 103 after cutting, the working end of the electric telescopic rod 207 is extended by the main body 101 of the film cutting machine 100, which controls the moving frame 210 to extend below the blade 104. During the lifting of the blade 104, the scraper 203 remains in contact with the side wall of the blade 104 under the restoring force of the spring 205. During the lifting of the blade 104, the scraper 203 scrapes off the residual adhesive stuck to the side wall of the blade 104. The residual adhesive falls into the collection box 211 inside the moving frame 210 below. The worker can clean the residual adhesive inside the fixed frame 201 periodically. When it is necessary to clean the collection box 211, the electric telescopic rod 207 is retracted by the controller set inside the film cutting machine host 101 inside the film cutting machine body 100. The rotating block 212 is manually rotated to overcome the torsion spring force so that it is disengaged from the card seat 213, and the collection box 211 can be pulled out from the moving frame 210 to clean the residual glue inside. like Figure 4 As shown, the inner wall of the fixed frame 201 on both sides of the electric telescopic rod 207 is provided with guide grooves 209. The end of the guide rod 208 provided on the side wall of the movable frame 210 is slidably disposed inside the guide groove 209. The end of the guide groove 209 is not connected to the outer side wall of the fixed frame 201. In this embodiment, the end of the guide rod 208 provided on the side wall of the movable frame 210 slides along the guide groove 209 opened on both sides of the inner wall of the fixed rod 202 to ensure the direction when the fixed frame 201 extends and retracts, and to ensure the stability of the fixed frame 201 when it moves. At the same time, the end of the guide groove 209 is not connected to the side wall of the fixed frame 201, ensuring that the guide rod 208 will not extend out of the guide groove 209 and cause damage to the equipment. like Figure 6 and Figure 7 As shown, a fixed seat 214 is provided on the top surface of the movable frame 210 near the electric telescopic rod 207. An auxiliary scraper 215 is elastically connected inside the fixed seat 214. The end of the auxiliary scraper 215 is slidably connected to the bottom surface of the scraper 203. In this embodiment, during the cutting process of the blade 104 pressing down, the scraper 203 is pushed away by the side wall of the blade 104. At this time, the auxiliary scraper 215 can scrape off the small amount of residual adhesive that may be adhered to the bottom surface of the scraper 203, keeping the scraper 203 clean and preventing the residual adhesive accumulated on the scraper 203 from causing secondary contamination to the blade 104. like Figure 7 As shown, the auxiliary scraper 215 is provided with a downwardly inclined adhesive guide strip 216 on the side wall facing the inside of the movable frame 210; In this embodiment, the guide strip 216 is typically made of flexible materials such as rubber or silicone, which can effectively guide residual adhesive scraped off from the auxiliary scraper 215 or naturally falling into the collection box 211 below, preventing residual adhesive from falling to other places and contaminating the adhesive strip cutting environment.

[0020] Working principle: The adhesive strip is fed into the working area inside the film cutting machine host 101 by the feeding conveyor belt 102. The hydraulic mechanism 103 drives the blade 104 to press down, completing the precise cutting of the adhesive strip. After the slitting is completed, the hydraulic mechanism 103 drives the blade 104 to rise. During the rising process of the blade 104, its side wall passes through the scraping mechanism 200, and the working end of the electric telescopic rod 207 extends out, so that the moving frame 210 moves to the bottom of the blade 104. Under the pre-tightening force of the spring 205, the scraper 203 closely fits the arc surface of the blade 104 and scrapes off the residual glue attached to the side wall of the blade 104. The scraped residual glue falls into the collection box 211 inside the moving frame 210 under the action of gravity. The residual glue is collected through the collection box 211, which makes it convenient for workers to clean the residual glue regularly. When the collection box 211 needs to be cleaned, the worker manually rotates the rotating block 212 to overcome the torsion spring force and disengage it from the card seat 213, so that the collection box 211 can be pulled out from the inside of the moving frame 210 and the residual glue collected inside the collection box 211 can be cleaned.

[0021] It should be noted that the electric telescopic pole 207 mentioned above is a device with relatively mature existing technology. The specific model can be selected according to actual needs. At the same time, the electric telescopic pole 207 can be powered by a built-in power supply or by AC power. The specific power supply method should be selected according to the situation, which will not be elaborated here.

[0022] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
