Description

TECHNICAL FIELD

[0001] The application relates to the field of cutting devices, in particular to a length-cutting device for adhesive tape with tension self-adjusting function. BACKGROUND

[0002] In the production process of adhesive tape, the adhesive tape is usually wound into a roll for transportation. Before use, some adhesive tapes need to be cut into a specified length, so a cutting device is needed to cut the adhesive tape.

[0003] The current cutting device mainly comprises a rack, a conveying station and a cutting station. The conveying station is used to place the wound adhesive tape and convey the adhesive tape to the cutting station. The cutting station works at the same frequency according to the set cutting requirement to cut the adhesive tape into the same length.

[0004] In actual use, when the cutting frequency at the cutting station deviates from the conveying frequency of the conveying station, the adhesive tape in the conveying process is prone to bottoming out, that is, the adhesive tape is stacked on the rack, causing the adhesive tape at the cutting station to bend, thereby affecting the final cutting accuracy, and thus needs to be improved. CONTENT OF THE INVENTION

[0005] In order to improve the above problems, the application provides a length-cutting device for adhesive tape with tension self-adjusting function.

[0006] The application provides a length-cutting device for adhesive tape with tension self-adjusting function, which adopts the following technical scheme:

[0007] A length-cutting device for adhesive tape with tension self-adjusting function is used to cut adhesive tape, comprising a feeding frame and a rack, wherein the feeding frame and the rack are connected, the feeding frame is provided with a feeding assembly and an adjusting assembly for adjusting tension, the rack is provided with a conveying assembly and a cutting assembly, the adjusting assembly comprises an adjusting frame and a plurality of tension rollers, the adjusting frame is rotatably connected with the feeding frame, and each tension roller is rotatably connected with the adjusting frame.

[0008] By adopting the above technical scheme, the adhesive tape moves to the cutting assembly after passing through the feeding assembly, the adjusting assembly and the conveying assembly in sequence, and the cutting assembly cuts the adhesive tape. In the process of conveying the adhesive tape, the adhesive tape drives the tension rollers at the corresponding position to rotate under the transmission of the feeding assembly and the conveying assembly, and the tension rollers drive the adjusting frame to rotate to adjust the tension in the process of conveying the adhesive tape, thereby realizing the function of automatically adjusting the tension, reducing the possibility of bottoming out in the process of conveying the adhesive tape, so that the cutting assembly can work more stably, thereby improving the cutting effect of the cutting device.

[0009] Preferably, the feeding assembly includes a storage roller and two feeding rollers arranged opposite to each other. The storage roller is rotatably connected to the feeding frame, and the two feeding rollers arranged opposite to each other are both rotatably connected to the feeding frame, with the two feeding rollers rotating in opposite directions.

[0010] By adopting the above technical solution, since the two feeding rollers rotate in opposite directions, when the conveyor belt passes through the two feeding rollers, the two feeding rollers can control the conveyor belt to move toward the conveying assembly, thereby facilitating the conveying of the conveyor belt.

[0011] Preferably, the feeding rack is provided with a first guide roller and a second guide roller, which are arranged opposite to each other on the feeding rack, and both the first guide roller and the second guide roller are rotatably connected to the feeding rack.

[0012] By adopting the above technical solution, the first guide roller and the second guide roller simultaneously provide guidance for the conveyor belt, which improves the stability of the conveyor belt during conveying and makes it less likely for the conveyor belt to come into contact with the feeding rack and the frame, so that the subsequent cutting components can cut the conveyor belt more stably.

[0013] Preferably, the frame is provided with a bracket, and a support frame for supporting the tape is slidably connected to the bracket.

[0014] By adopting the above technical solution, the support frame provides support for the tape, which further reduces the possibility of the tape bottoming out during the adjustment of tape tension by the adjustment component.

[0015] Preferably, the support frame is rotatably connected to several pressure plates.

[0016] By adopting the above technical solution, the pressure plate provides support for the conveyor belt passing through the support frame, making it less likely for the conveyor belt to curl up on the support frame, thereby further improving the stability of the conveyor belt during conveying.

[0017] Preferably, an adjusting rod is rotatably connected to the support frame, a first gear is coaxially connected to the adjusting rod, and a rack is provided on the bracket, with the first gear meshing with the rack.

[0018] By adopting the above technical solution, when the position of the support frame needs to be adjusted, the worker rotates the adjusting rod, which in turn drives the adjusting gear to rotate. The adjusting gear, in conjunction with the rack, controls the movement of the support frame along the support structure, allowing the support frame to adapt to conveyor belts with different conveying requirements.

[0019] Preferably, the support frame is provided with a movable plate, and a pulley is rotatably connected to the movable plate, the pulley abutting against the support.

[0020] By adopting the technical scheme, the pulley changes the sliding friction between the support frame and the support into rolling friction, reduces the friction between the support frame and the support, and thus improves the stability of the support frame during movement.

[0021] Preferably, the conveying assembly comprises two groups of conveying members arranged oppositely, the conveying members comprising first conveying rollers and second conveying rollers, the first conveying rollers and the second conveying rollers being rotationally connected to the rack, the first conveying rollers and the second conveying rollers rotating in the same direction, and the first conveying rollers and the second conveying rollers being provided with conveying rings thereon, adjacent two first conveying rollers rotating in opposite directions, and adjacent two second conveying rollers rotating in opposite directions.

[0022] By adopting the technical scheme, since the first conveying rollers and the second conveying rollers in the two groups of conveying members rotate in opposite directions, the two groups of conveying members can convey the adhesive tape to the cutting assembly. During the conveying of the adhesive tape, the conveying rings provide guidance for the adhesive tape, further reducing the phenomenon of edge lifting of the adhesive tape, improving the stability of the adhesive tape moving to the cutting assembly, and providing convenience for the subsequent cutting assembly to cut the adhesive tape more stably.

[0023] In summary, the present application has at least one of the following beneficial technical effects:

[0024] 1. By providing the adjusting assembly, the adjusting assembly adjusts the tension in the conveying process of the adhesive tape in real time, so that the adhesive tape is less likely to have the phenomenon of bottoming or edge lifting, so that the cutting assembly can cut the adhesive tape more stably, thereby improving the cutting effect and cutting efficiency of the cutting device;

[0025] 2. By providing the support frame and the pressing plate, the support frame provides support for the adhesive tape during the conveying process, and the pressing plate provides limiting for the adhesive tape during the conveying process, further improving the stability during the conveying process of the adhesive tape, thereby further improving the cutting efficiency of the cutting device;

[0026] 3. By providing the conveying ring, the conveying ring provides guidance for the adhesive tape, so that the adhesive tape conveyed to the cutting assembly is less likely to have the phenomenon of edge lifting, so that the cutting assembly can cut the adhesive tape more stably.

DETAILED DESCRIPTION

[0030] The following will be described in detail with reference to the accompanying drawings. Figures 1-2 The application is further described in detail.

[0031] The application discloses a length-cutting device for adhesive tape with tension self-adjusting function. Figure 1 The length-cuting device for adhesive tape with tension self-adjusting function is used for cutting adhesive tape, and comprises a feeding frame 1 and a rack 2. The feeding frame 1 and the rack 2 are fixed. The feeding frame 1 is provided with a feeding assembly 3 and an adjusting assembly 4 for adjusting the tension of the adhesive tape. The feeding frame 1 is also provided with a conveying assembly 5 and a cutting assembly 6. The feeding assembly 3 sequentially conveys the adhesive tape to the adjusting assembly 4 and the conveying assembly 5. The conveying assembly 5 conveys the adhesive tape to the cutting assembly 6. The cutting assembly 6 cuts the adhesive tape. In the process of conveying the adhesive tape, the adjusting assembly 4 adjusts the tension of the adhesive tape in real time, reduces the phenomenon that the adhesive tape is accumulated or warped at the cutting assembly 6, so that the cutting assembly 6 can cut the adhesive tape more stably, thereby improving the cutting efficiency and cutting effect of the cutting device.

[0032] Referring to Figure 1 The feeding assembly 3 comprises a storage roller 31 and two oppositely arranged feeding rollers 32. The storage roller 31 is used for placing the roll-shaped adhesive tape, and the storage roller 31 and the two feeding rollers 32 are both rotationally connected to the feeding frame 1. The two feeding rollers 32 rotate in opposite directions. The two feeding rollers 32 are both coaxially fixed with first gears 321, and the two first gears 321 are engaged. The feeding frame 1 is fixed with a first motor 11. The output end of the first motor 11 is coaxially connected with one of the first gears 321.

[0033] Referring to Figure 1 The adjusting assembly 4 comprises an adjusting frame 41 and a plurality of tension rollers 42. The adjusting frame 41 is rotationally connected to the feeding frame 1, and each tension roller 42 is rotationally connected to the adjusting frame 41.

[0034] The worker places the tape roll on the storage roller 31, and then guides the tape between the two feeding rollers 32. The first motor 11 drives the first gear 321 to rotate, and under the driving action of the other first gear 321, the two feeding rollers 32 rotate in opposite directions, thereby automatically guiding the tape. The worker then guides the tape to pass through the various tension rollers 42 in sequence, and then guides the tape to the conveying assembly 5. The conveying assembly 5 can convey the tape to the cutting assembly 6, thereby achieving the function of automatically conveying the tape. At the same time, during the conveying of the tape, the tape controls the rotation of the various tension rollers 42 and drives the adjustment frame 41 to rotate, thereby adjusting the tension of the tape in real time during conveying, reducing the phenomenon of bottoming or accumulation during tape conveying, so that the cutting assembly 6 can cut the tape more stably.

[0035] With reference to Figure 1 , in order to improve the stability of the tape conveying, the first guide roller 12 and the second guide roller 13 are rotatably connected to the feeding frame 1 and are oppositely arranged. The tape moves between the two feeding rollers 32 after passing through the first guide roller 12. The tape passes through the second guide roller 13 after passing through the various tension rollers 42, so that the tape is less likely to contact the feeding frame 1 and the rack 2, further improving the stability of the tape conveying.

[0036] With reference to Figure 2 , the rack 21 is fixed on the rack 2, the supporting frame 22 for supporting the tape is slidably connected to the rack 21, and the plurality of pressing plates 221 are rotatably connected to the supporting frame 22.

[0037] The tape that passes through the second guide roller 13 moves to the supporting frame 22, and the pressing plates 221 provide limiting for the tape under the action of their own gravity, on the one hand, so that the tape is less likely to bottom on the rack 2, and on the other hand, so that the tape is less likely to have a curled edge when passing through the supporting frame 22, so that the tape can be conveyed more stably to the conveying assembly 5.

[0038] With reference to Figure 1 and Figure 2 , in order to adapt the supporting frame 22 to different tapes with different conveying requirements, the adjusting rod 222 is rotatably connected to the supporting frame 22, the adjusting gear 223 is coaxially fixed on the adjusting rod 222, the rack 211 is fixed on the rack 21, and the adjusting gear 223 is engaged with the rack 21. The moving plate 224 is fixed on the supporting frame 22, the pulley 225 is rotatably connected to the moving plate 224, and the pulley 225 abuts against the rack 21.

[0039] The worker controls the rotation of the adjusting lever 222, the adjusting lever 222 drives the rotation of the adjusting gear 223, and under the cooperation of the rack 211, the movement of the supporting frame 22 can be controlled. During the movement of the supporting frame 22, the pulley 225 changes the sliding friction between the supporting frame 22 and the support 21 into rolling friction, reduces the friction between the supporting frame 22 and the support 21, and makes the worker more stable to adjust the position of the supporting frame 22, so that the supporting frame 22 adapts to the different conveying requirements of the rubber belt.

[0040] Referring to Figure 2 , the support 21 is fixed with a support seat 212, and the support seat 212 is provided with a sponge pad 213 near one side of the support 21. The rubber belt after the second guide roller 13 moves to the supporting frame 22 after passing through the gap between the sponge pad 213 and the support 21. At this time, the sponge pad 213 cleans the rubber belt, so that the impurities adhered to the rubber belt do not easily affect the subsequent cutting action.

[0041] Referring to Figure 1 , the conveying assembly 5 includes two groups of conveying members arranged oppositely, the conveying members include first conveying rollers 51 and second conveying rollers 52, the first conveying rollers 51 and the second conveying rollers 52 are both rotationally connected to the rack 2, and the first conveying rollers 51 and the second conveying rollers 52 are both provided with conveying rings 53. The rotation directions of the first conveying rollers 51 and the second conveying rollers 52 are the same, the rotation directions of adjacent two first conveying rollers 51 are opposite, and the rotation directions of adjacent two second conveying rollers 52 are opposite.

[0042] The second gears 511 are coaxially fixed on the two first conveying rollers 51, and the two second gears 511 are meshed. The second motor 23 is fixed on the rack 2, and the output end of the second motor 23 is coaxially connected with one of the second gears 511.

[0043] The second motor 23 controls the rotation of the second gears 511, and under the transmission of the other second gear 511, the adjacent two first conveying rollers 51 or the adjacent two second conveying rollers 52 rotate in opposite directions. The rubber belt guided by the supporting frame 22 passes between the two groups of conveying members, and the rubber belt is conveyed to the cutting assembly 6. At the same time, under the guidance of the conveying ring 53, the flatness of the rubber belt conveyed to the cutting assembly 6 is improved, thereby improving the stability of the cutting assembly 6 when cutting the rubber belt.

[0044] Referring to Figure 1 , the first transition roller 24 and the second transition roller 25 are rotationally connected to the rack 2, and the rubber belt passing through the supporting frame 22 moves between the two groups of conveying members after passing through the first transition roller 24 and the second transition roller 25 in sequence. The first transition roller 24 and the second transition roller 25 further adjust the tension of the rubber belt during conveying, so that the rubber belt moves more stably to the conveying assembly 5.

[0045] Referring toFigure 2 The cutting assembly 6 comprises a cutting frame 61 fixed on the frame 2 and a cutting knife 62. The cutting frame 61 is fixed with a cylinder 63, and the output end of the cylinder 63 is connected with the cutting knife 62 and controls the cutting knife 62 to reciprocate vertically. The adhesive tape conveyed by the conveying assembly 5 moves to the cutting knife 62. The cylinder 63 works according to the set program and controls the cutting knife 62 to move up and down at a certain frequency, so as to cut the adhesive tape into the set length.

[0046] The implementation principle of the adhesive tape fixed-length cutting device with the tension self-adjusting function is that, in the process of cutting the roll-shaped adhesive tape into the set length, the feeding assembly 3 and the conveying assembly 5 are used to automatically convey the adhesive tape, and the adjusting assembly 4 is used to adjust the tension of the adhesive tape in real time, so that the adhesive tape is not prone to the bottom supporting or edge lifting phenomenon, and the cutting assembly 6 can stably cut the adhesive tape, thereby improving the cutting efficiency and cutting effect of the cutting device.

[0047] The above are the preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, any equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
