Description

Technical Field

[0001] This utility model relates to the field of slitting machines, specifically to a slitting machine capable of automatically removing glue. Background Technology

[0002] As a highly efficient piece of equipment, slitting machines can quickly and accurately cut various tapes and adhesive-containing materials (such as double-sided tape and pressure-sensitive adhesive materials) to meet the market's demand for products with diverse specifications. However, since these materials themselves contain adhesives, adhesive residue will inevitably remain on the cutting blades during the slitting process.

[0003] Residual adhesive on cutting tools has the following disadvantages: 1. It can cause deviations or burrs during cutting, leading to decreased cutting accuracy and affecting product quality. 2. Residual adhesive on the cutting tool may transfer to the product surface, affecting not only appearance but also product function. 3. Cleaning adhesive residue on the cutting tool requires frequent machine shutdowns for maintenance, thus reducing production efficiency and increasing production costs. Utility Model Content

[0004] Based on this, and in response to the aforementioned technical problems, this utility model provides a slitting machine capable of automatically removing glue.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A slitting machine capable of automatic adhesive removal includes a frame, a rotating shaft mounted on the frame, and blades arranged at equal intervals on the rotating shaft. It also includes an adhesive removal mechanism capable of removing residual adhesive from the blades. The adhesive removal mechanism includes a fixed rod mounted on the frame below the rotating shaft, a first mounting bracket rotatably mounted on the fixed rod, and an axially extending first felt mounted on the first mounting bracket. When the first mounting bracket is flipped upward, the first felt contacts all the blades.

[0007] Using the above technical solution, when the first mounting bracket flips upward, the cutting edge of the tool cuts into the first felt, allowing the cutting edge to rub through the felt and thus removing any adhesive adhering to it. This not only avoids cutting deviations or burrs caused by adhesive residue but also prevents adhesive from transferring to the product surface. Furthermore, cleaning can be completed without disassembling the tool, reducing equipment maintenance frequency and downtime, improving production efficiency, and making it suitable for continuous production needs.

[0008] In a specific embodiment of this utility model: the first felt is impregnated with release silicone oil. Using the above technical solution, the release silicone oil reduces the adhesive force of the adhesive, making it easier for adhesive residue on the tool to be wiped off by the felt. It also prevents the wiped-off adhesive from sticking to the felt, thereby extending the service life of the felt. Furthermore, the release silicone oil acts as a lubricant, further extending the service life of the tool.

[0009] In a specific embodiment of this utility model: a second mounting bracket may be rotatably mounted on the fixed rod, and an axially extending second felt is mounted on the second mounting bracket. The second felt is impregnated with release silicone oil. The length of the second mounting bracket is longer than the length of the first mounting bracket. The second mounting bracket is located outside the first mounting bracket, so that when the second mounting bracket is flipped upward, it can flip over the first mounting bracket, so that the second felt can contact all the cutting tools.

[0010] Using the above technical solution, when the second mounting bracket is flipped upward, the second felt impregnated with release silicone oil will come into contact with all the cutting tools, further removing adhesive residue from the surface of the cutting tools.

[0011] In a specific embodiment of this utility model: both the first mounting bracket and the second mounting bracket include a lower pressure plate and an upper pressure plate that are spaced apart and connected together by bolts. Both ends of the lower pressure plate are connected to connecting plates, and each connecting plate has a through hole. The fixing rod passes through all the through holes in sequence.

[0012] In a specific embodiment of this utility model: both the first mounting bracket and the second mounting bracket are provided with a locking structure. The locking structure includes a bolt hole and a locking bolt provided on the connecting plate and communicating with the corresponding through hole. The locking bolt is tightened in the bolt hole and its end abuts against the fixing rod.

[0013] In this specific embodiment of the invention: the two ends of the lower pressure plate are respectively mounted on two corresponding connecting plates via felt position adjustment structures. Each felt position adjustment structure includes a slider, a support block, and an adjusting bolt. The end face of the connecting plate away from the fixed rod has a groove. The protrusion of the slider is embedded in the groove and can slide along it. The two ends of the lower pressure plate are respectively connected to the corresponding slider. The support block is located on the outer surface of the connecting plate and the slider and is connected to the connecting plate. The support block and the slider have communicating threaded holes, and the adjusting bolt is installed in the threaded holes. Using this structure, by rotating the adjusting bolt, the slider can move up and down along the groove, thereby adjusting the depth to which the cutting edge of the tool cuts into the felt, thus achieving a better wiping effect.

[0014] In a specific embodiment of this utility model: the contact surface between the slider and the lower pressure plate is an inclined surface.

[0015] In a specific embodiment of this utility model: both the first felt and the second felt are made of polyester fiber. Using this structure, the polyester fiber felt has the advantages of being wear-resistant and low-cost.

[0016] In summary, when the first and second mounting brackets of this invention are flipped upwards, the first and second felts, impregnated with release silicone oil, come into contact with all the cutting tools. The friction of the two felts removes any adhesive residue from the tool surface, preventing cutting deviations or burrs caused by adhesive residue and preventing residual adhesive from transferring to the product surface. Secondly, the release silicone oil also acts as a lubricant, thus extending the tool's lifespan. Furthermore, cleaning can be completed without disassembling the tools, reducing equipment maintenance frequency and downtime, improving production efficiency, and making it suitable for continuous production needs. Attached Figure Description

[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] Figure 1 This is a schematic diagram of the structure of a slitting machine capable of automatically removing glue according to this utility model. Detailed Implementation

[0019] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1 As shown, this utility model is a slitting machine capable of automatic glue removal, including a frame and a rotating shaft 11 mounted on the frame. Circular blades 12 arranged at equal intervals are mounted on the rotating shaft 11. A motor (not shown in the figure) is also connected to one end of the rotating shaft 11 to drive its rotation. It also includes a glue removal mechanism 20 capable of removing residual adhesive from the blades 12.

[0021] The adhesive removal mechanism 20 includes a fixed rod 21 mounted on the frame below the rotating shaft, a first mounting bracket 22 rotatably mounted on the fixed rod 21, and an axially extending first felt 23 mounted on the first mounting bracket 22. During production, the first mounting bracket 22 is flipped upwards, allowing the cutting edge of the disc cutter 12 to cut into the first felt 23, wiping away the adhesive adhering to it. Furthermore, cleaning can be completed without disassembling the cutter, reducing equipment maintenance frequency and downtime, improving production efficiency, and meeting the needs of continuous production.

[0022] In this embodiment, the first felt 23 is impregnated with release silicone oil. The release silicone oil reduces the adhesive's adhesion, making it easier to remove adhesive residue from the tool by wiping it off with the first felt. It also prevents the removed adhesive from sticking to the first felt, thus extending its service life. Furthermore, the release silicone oil acts as a lubricant, further extending the tool's lifespan.

[0023] In this embodiment, a second mounting bracket 24 can also be rotatably mounted on the fixing rod 21. An axially extending second felt 25 is mounted on the second mounting bracket 24. Release silicone oil is impregnated in the second felt 25. The length of the second mounting bracket 24 is longer than the length of the first mounting bracket 22, and the second mounting bracket 24 is located outside the first mounting bracket 22. This structure avoids interference, allowing the second mounting bracket to flip upwards and pass over the first mounting bracket. The cutting edge of the disc cutter cuts into the second felt, and the resulting cutting edge also rubs through the second felt, further wiping away any adhesive adhering to it. Furthermore, the adhesive is less likely to stick to the second felt, thus extending the service life of the second felt. Simultaneously, it lubricates the cutting edge of the cutter, extending its service life.

[0024] In this embodiment, both the first felt 23 and the second felt 25 are made of polyester fiber. This structure provides the polyester fiber felt with advantages such as wear resistance and low cost.

[0025] In this embodiment, both the first mounting bracket 22 and the second mounting bracket 24 include a lower pressure plate 221 and an upper pressure plate 222 that are spaced apart and connected together by bolts. Connecting plates 223 are connected to both ends of the lower pressure plate 221. Each connecting plate 223 has a through hole 224, through which the fixing rod 21 passes sequentially. During assembly, each felt is placed between the corresponding lower pressure plate 221 and upper pressure plate 222, and the felt is clamped and fixed by tightening the bolts.

[0026] In this embodiment, both the first mounting bracket 22 and the second mounting bracket 24 are provided with a locking structure 30. This locking structure 30 is used to fix and position the mounting bracket. The locking structure 30 includes a bolt hole on the connecting plate communicating with the through hole 224 and a locking bolt 32. The locking bolt 32 is tightened into the bolt hole, with its end abutting against the fixing rod 21, thus fixing the mounting bracket in place. During operation, the locking bolt is loosened, the mounting bracket is flipped upwards until the felt contacts the tool, and finally, the locking bolt is tightened to fix the mounting bracket in place.

[0027] In this embodiment, two corresponding connecting plates 223 are mounted on both ends of the lower pressure plate 221 via felt position adjustment structures 40. Each felt position adjustment structure 40 includes a slider 41, a support block 42, and an adjusting bolt 43. A groove 44 is provided on the end face of the connecting plate 223 away from the fixing rod 21. The protrusion 411 of the slider 41 is embedded in the groove 44 and can slide up and down along the groove 44. Both ends of the lower pressure plate 221 are fixedly connected to the corresponding slider 41 by bolts. The support block 42 is located on the outer surface of the connecting plate 223 and the slider 41. The support block 42 is fixed to the connecting plate 223 by bolts. The support block 42 and the slider 41 have communicating threaded holes 45, and the end of the adjusting bolt 43 passes through the threaded holes 45 of the support block and the slider in sequence. By rotating the adjusting bolt, the slider can move up and down along the groove, thereby adjusting the depth to which the blade of the cutter cuts into the felt, thus achieving a better wiping effect.

[0028] In this embodiment, the contact surface between the slider 41 and the lower pressure plate 221 is an inclined surface. This structure allows the cutting edge of the disc cutter to cut into the felt radially towards the upper side of the felt after the first and second mounting brackets are flipped and fixed upwards, ensuring sufficient contact between the cutting edge and the felt.

[0029] The above describes an automatic adhesive removal slitting machine according to this utility model. During operation, first loosen the locking bolts 32, then flip the first mounting bracket 22 and the second mounting bracket 24 upwards, so that the first felt 23 and the second felt 25, impregnated with release silicone oil, contact the cutting edges of all the blades. Then, tighten all the locking bolts 32 to fix the first mounting bracket 22 and the second mounting bracket 24 in place. The double felt friction scrapes or absorbs residual adhesive from the blade surface, preventing cutting deviations or burrs caused by residual adhesive on the blades, and also preventing adhesive transfer to the product surface. By rotating the adjusting bolts, the slider can move up and down along the groove, thereby adjusting the depth to which the blade cutting edge enters the felt, achieving a better wiping effect.

[0030] In summary, applying release silicone oil to the felt and then rubbing it against the cutting tool not only removes or absorbs adhesive residue from the tool surface, preventing cutting deviations or burrs caused by adhesive residue, but the release silicone oil also acts as a lubricant, thus extending the tool's lifespan. Furthermore, cleaning can be completed without disassembling the tool, reducing equipment maintenance frequency and downtime, improving production efficiency, and making it suitable for continuous production needs.

[0031] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
