Description

Technical Field

[0001] This utility model relates to the field of masking tape production technology, and in particular to a tape cutting machine for processing industrial high-temperature masking tape. Background Technology

[0002] Industrial high-temperature masking tape is a type of adhesive tape specifically designed for use in high-temperature environments in industrial settings. It maintains stable physical and chemical properties at high temperatures. Different models of high-temperature masking tape have different temperature resistance ranges, generally operating continuously between 120℃ and 600℃. It can also quickly and firmly adhere to the surface of various materials at both room temperature and high temperatures, ensuring that the tape will not fall off or shift during high-temperature processes, and effectively preventing the penetration of coatings, paints, etc.

[0003] A search revealed that the utility model patent with authorization announcement number CN221968175U discloses a tape cutting machine for processing industrial high-temperature masking tape. Through the cooperation of the internal components of the internal clamping mechanism, tape rolls of various inner diameters can be fixed, thereby avoiding damage to the cutter caused by unstable fixing of the tape roll and reducing the scrap rate of the cutter.

[0004] Although the aforementioned tape cutting machine can cut tape rolls of different inner diameters, in actual tape cutting, after cutting the previous roll of industrial high-temperature masking tape, it is necessary to unfix and remove it before fixing and cutting the next roll of industrial high-temperature masking tape. The interval between two adjacent tape cutting operations is relatively long, and the overall tape cutting efficiency still needs to be improved.

[0005] Therefore, it is necessary to invent a tape cutter for processing industrial high-temperature masking tape to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a tape cutting machine for processing industrial high-temperature masking tape. This machine can simultaneously perform tape cutting and loading / unloading operations, thereby effectively shortening the time interval between adjacent cutting operations and improving overall cutting efficiency. This addresses the problem mentioned in the background art where, in the actual tape cutting process, after cutting the previous roll of industrial high-temperature masking tape, it is necessary to unscrew and remove it before fixing and cutting the next roll, resulting in a long interval between adjacent cutting operations and insufficient overall cutting efficiency.

[0007] According to one aspect of this disclosure, the following technical solution is provided: a tape cutting machine for processing industrial high-temperature masking tape, comprising:

[0008] A tape cutting assembly for cutting fixed industrial high-temperature masking tape;

[0009] A shifting assembly includes a back plate fixedly mounted on the rear side of the top of the base. Locking holes are provided on both sides of the front of the back plate. A switching shaft is rotatably driven through the center of the front of the back plate via a bearing. A shifting disc is fixedly sleeved at the front end of the switching shaft. A handwheel is fixedly sleeved at the rear end of the shifting disc. A locking pin is slidably driven through the right side of the back of the handwheel. The front end of the locking pin is slidably inserted into the inner side of an adjacent locking hole. A limit ring is fixedly sleeved on the outer side of the locking pin.

[0010] Two sets of tape roll fixing mechanisms are used to fix the industrial high-temperature masking tape to be cut.

[0011] According to at least one embodiment of the present disclosure, a tape cutting machine for processing industrial high-temperature masking tape includes a base, a side plate fixedly disposed on the top left side of the base, and an electric push rod A fixedly disposed through the top left side of the side plate.

[0012] According to at least one embodiment of the present disclosure, a tape cutter for processing industrial high-temperature masking tape has an output shaft of the electric push rod A that passes through a side plate and is fixedly connected to a fixed frame A. Guide rods A that slide through the side plate are fixedly provided at both ends of the left side of the fixed frame A.

[0013] According to at least one embodiment of the present disclosure, a tape cutting machine for processing industrial high-temperature masking tape has a rotating shaft rotatably nested inside the fixed frame A via bearings, and a plurality of cutting blades are uniformly fixed outside the rotating shaft. A motor A, which is drively connected to the rotating shaft, is fixedly installed at the end of the fixed frame A.

[0014] According to at least one embodiment of the present disclosure, a tape cutting machine for processing industrial high-temperature masking tape includes a fixed frame B fixedly disposed on the front side of the transposition plate, and a motor B fixedly disposed on the inner side of the fixed frame B.

[0015] According to at least one embodiment of the present disclosure, a tape cutter for processing industrial high-temperature masking tape has a support shaft that is rotatably nested on the front of the fixed frame B and is connected to the motor B via a bearing. Support components are provided on both sides of the support shaft.

[0016] According to at least one embodiment of the present disclosure, a tape cutting machine for processing industrial high-temperature masking tape includes any set of support components including a fixed frame C fixedly disposed on the side of a support shaft, an electric push rod B fixedly disposed inside the fixed frame C, the output shaft of the electric push rod B slidingly passing through the fixed frame C and fixedly connected to an arc-shaped support plate, and guide rods B that slide through the fixed frame C fixedly disposed at both ends of the left side of the arc-shaped support plate.

[0017] The technical effects and advantages of this utility model are as follows:

[0018] This invention incorporates a switching component. When the tape cutting assembly cuts the previous roll of industrial high-temperature masking tape fitted to the outside of the left tape roll fixing mechanism, it simultaneously attaches and fixes the next roll of industrial high-temperature masking tape to the outside of the right tape roll fixing mechanism. After the tape roll fixing mechanism completes the cutting and reset of the previous roll, the locking pin is pulled out from the adjacent locking hole to release the handwheel. The handwheel is then rotated, which drives the switching disc via the switching shaft, thus switching the two tape roll fixing mechanisms. The locking pin is then pushed and inserted into the adjacent locking hole to lock the mechanism. At this point, the tape roll fixing mechanism cuts the next roll of industrial high-temperature masking tape, and simultaneously removes the previous roll after cutting. Compared to existing technologies, this invention allows for simultaneous cutting and loading / unloading of the industrial high-temperature masking tape, effectively shortening the time interval between adjacent cutting operations and improving overall cutting efficiency.

[0027] For descriptive purposes, this disclosure may use spatial relative terms such as “below,” “under,” “below,” “down,” “above,” “above,” “higher,” and “side (e.g., in a “sidewall”)” to describe the relationship between one component and another component as shown in the accompanying drawings. In addition to the orientations depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacture. For example, if the device in the drawings is flipped, a component described as “below” or “under” other components or features would subsequently be positioned “above” said other components or features. Thus, the exemplary term “below” can encompass both “above” and “below” orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), thus interpreting the spatial relative descriptive terms used herein accordingly.

[0028] Figure 1 This is a schematic diagram of the overall structure of a tape cutter for processing industrial high-temperature masking tape according to one embodiment of the present disclosure.

[0029] Figure 2 This is a partial structural diagram of the tape cutting assembly 1 and the transposition assembly 2 of a tape cutting machine for processing industrial high-temperature masking tape according to one embodiment of the present disclosure.

[0030] Figure 3 This is a partial structural diagram of the transposition assembly 2 and the tape roll fixing mechanism 3 of a tape cutter for processing industrial high-temperature masking tape according to one embodiment of the present disclosure.

[0031] like Figures 1-3 As shown, the tape cutting machine for processing industrial high-temperature masking tape disclosed herein mainly consists of a tape cutting assembly 1, a switching assembly 2, and two sets of tape roll fixing mechanisms 3. The tape cutting assembly 1 is responsible for accurately cutting the fixed tape, the switching assembly 2 enables rapid switching between the two sets of tape roll fixing mechanisms to simultaneously perform tape cutting and loading / unloading operations, and the tape roll fixing mechanism 3 is used to firmly clamp the tape roll to be cut, ensuring no deviation during the cutting process. The three work together to significantly shorten the interval between two adjacent tape cutting operations and improve the overall processing efficiency.

[0032] like Figure 2As shown in this disclosure, the slicing assembly 1 includes a base 11. A side plate 12 is fixedly disposed on the top left side of the base 11. An electric push rod A13 is fixedly disposed through the top left side of the side plate 12. The output shaft of the electric push rod A13 passes through the side plate 12 and is fixedly connected to a fixing frame A14. Guide rods A15 that slide through the side plate 12 are fixedly disposed at both ends of the left side of the fixing frame A14. A rotating shaft 16 is rotatably nested inside the fixing frame A14 through a bearing. Multiple cutters 17 are evenly fixedly disposed on the outside of the rotating shaft 16. A motor A18 that is drivenly connected to the rotating shaft 16 is fixedly disposed at the end of the fixing frame A14.

[0033] Therefore, the tape roll fixing mechanism 3 moves the industrial high-temperature masking tape to the tape cutting station. At the same time, after the switching component 2 is locked, the electric push rod A13 drives the fixing frame A14, which is guided by the guide rod A15, to move continuously to the right. Simultaneously, the motor A18 drives multiple cutters 17 to rotate through the rotating shaft 16 (the speed can be adjusted according to the tape thickness, usually 300-600 r / min). When the fixing frame A14 moves to the right, it drives multiple rotating cutters 17 to move synchronously to the right through the rotating shaft 16. As the multiple cutters 17 continue to rotate and move to the right, they contact the industrial high-temperature masking tape and cut it. After the subsequent cutting is completed, the electric push rod A13 drives the fixing frame A14 to move to the left to reset, thereby resetting the multiple cutters 17.

[0034] like Figure 2 and Figure 3 As shown, in a preferred embodiment, the shifting component 2 includes a back plate 21 fixedly disposed on the rear side of the top of the base 11. Locking holes 22 are provided on both sides of the front of the back plate 21. A switching shaft 23 is rotatably disposed through the center of the front of the back plate 21 via a bearing. A shifting disk 24 is fixedly sleeved at the front end of the switching shaft 23. A handwheel 25 is fixedly sleeved at the rear end of the shifting disk 24. A locking pin 26 is slidably disposed through the right side of the back of the handwheel 25. The front end of the locking pin 26 is slidably inserted into the inner side of the adjacent locking hole 22. A limit ring 27 is fixedly sleeved on the outer side of the locking pin 26.

[0035] Therefore, when the tape cutting assembly 1 cuts the previous roll of industrial high-temperature masking tape fitted to the outside of the left tape roll fixing mechanism 3, it can fit the next roll of industrial high-temperature masking tape onto the outside of the right tape roll fixing mechanism 3 and fix it in place. After the tape roll fixing mechanism 3 has finished cutting the previous roll of industrial high-temperature masking tape and reset, the locking pin 26 is pulled out from the adjacent locking hole 22 to release the lock of the handwheel 25. Then, the handwheel 25 is rotated (rotation angle is 180 degrees). When the handwheel 25 rotates, it drives the switching shaft 23. The rotating disc 24 rotates, thereby causing the two sets of tape roll fixing mechanisms 3 to switch positions. Then, the locking pin 26 is pushed and inserted into the inner side of the adjacent locking hole 22 to lock. At this time, the tape roll fixing mechanism 3 cuts the next roll of industrial high temperature masking tape. At the same time, the previous roll of industrial high temperature masking tape is removed during this process. Compared with the existing technology, the cutting and loading / unloading operations of industrial high temperature masking tape can be performed simultaneously, thereby effectively shortening the time interval between two adjacent cutting operations and effectively improving the overall cutting efficiency.

[0036] In addition, to avoid the handwheel 25 continuously rotating in one direction and affecting the wiring between the motor B32 and the electric push rod B35, when the two sets of tape roll fixing mechanisms 3 are switched by driving the handwheel 25, the handwheel 25 is rotated clockwise and counterclockwise repeatedly.

[0037] like Figure 3 As shown in this disclosure, any set of tape roll fixing mechanisms 3 includes a fixing frame B31 fixedly disposed on the front of the transposition plate 24. A motor B32 is fixedly disposed on the inner side of the fixing frame B31. A support shaft 33, which is connected to the motor B32, is rotatably nested on the front of the fixing frame B31 through a bearing. Support components are provided on both sides of the support shaft 33. Any set of support components includes a fixing frame C34 fixedly disposed on the side of the support shaft 33. An electric push rod B35 is fixedly disposed on the inner side of the fixing frame C34. The output shaft of the electric push rod B35 slides through the fixing frame C34 and is fixedly connected to an arc-shaped support plate 36. The arc-shaped support plate 36 is made of wear-resistant rubber material, which avoids damage to the inner ring of the tape roll. Guide rods B37, which slide through the fixing frame C34, are fixedly disposed at both ends of the left side of the arc-shaped support plate 36. The guide rods B37 can prevent the arc-shaped support plate 36 from shifting and ensure the stability of the movement.

[0038] Therefore, when fixing the industrial high-temperature masking tape, the industrial high-temperature masking tape is sleeved on the outside of the two arc-shaped support plates 36 and the position of the industrial high-temperature masking tape is adjusted to ensure the subsequent tape cutting accuracy. Then, the electric push rod B35 drives its output shaft to extend, and the output shaft of the electric push rod B35 drives the arc-shaped support plate 36 guided by the guide rod B37 to move outward continuously. As the two arc-shaped support plates 36 move outward continuously, the industrial high-temperature masking tape is supported and fixed by the two arc-shaped support plates 36. When the tape roll fixing mechanism 3 moves the industrial high-temperature masking tape to the tape cutting station under the drive of the switching component 2, the motor B32 drives the two arc-shaped support plates 36 to rotate at a constant speed through the support shaft 33 until the industrial high-temperature masking tape is cut after one rotation.

[0039] It should be noted that, in order to avoid excessive rotation of the support shaft 33 affecting the wiring of the electric push rod B35, after the support shaft 33 completes one rotation to cut the industrial high-temperature masking tape, the motor B32 drives the support shaft 33 to rotate in the opposite direction to achieve reset.

[0040] In summary, through the coordinated work of the above components, this tape cutting machine can shorten the interval between two adjacent tape cutting operations to less than 1 / 3 of that of traditional equipment (traditional equipment needs to wait for the previous roll to be unloaded and the next roll to be loaded before it can start cutting, while this equipment can complete the process simultaneously), significantly improving the batch processing efficiency of industrial high-temperature masking tape.

[0041] It should also be noted that any content not described in detail in this specification is prior art known to those skilled in the art.

[0042] Those skilled in the art should understand that the above embodiments are merely for illustrating the present disclosure and are not intended to limit the scope of the disclosure. Those skilled in the art can make other changes or modifications based on the above disclosure, and these changes or modifications still fall within the scope of the present disclosure.
