Description

Technical Field

[0001] This utility model relates to the field of tape machine technology, and in particular to a multi-station tape machine roll tension adjustment mechanism. Background Technology

[0002] A tape machine is an automated device used for coating, slitting, and winding tape, achieving continuous production through multi-station collaboration. Its core component requires a tension adjustment mechanism, as differences in unwinding and rewinding speeds during roll material processing can easily lead to tape slack or tightness, causing breakage, wrinkles, or uneven bonding.

[0003] According to the Chinese patent "A Tape Adjustment Mechanism for a Tape Applying Machine" authorized announcement number "CN217867352U", this utility model uses a drive motor to drive a lead screw to rotate. The lifting plate rises and falls under the action of the lead screw and the long groove, so that the pressing plate rises and falls synchronously with the lifting plate to press the tape. This makes it easy to adjust the tension of the tape according to the material of the tape. The spring has a certain protective and buffering effect on the pressing plate and the tape, preventing the pressing plate from breaking the tape.

[0004] Although the aforementioned application can use a screw to drive the lifting plate to lift and tighten the tape with a pressing plate, thereby adjusting the tension of the tape, the device requires a spring between the lifting plate and the pressing plate to provide cushioning and protection to prevent the tape from breaking. The spring force increases linearly with the compression distance, requiring operators to precisely control the lifting distance of the lifting plate, which places high demands on the operator's precision and is inconvenient for operators to operate.

[0005] Therefore, a multi-station tape machine roll tension adjustment mechanism is proposed to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a multi-station tape machine roll tension adjustment mechanism to solve the above-mentioned problems, thereby improving the inconvenience for operators.

[0007] The present invention achieves the above objectives through the following technical solution: a multi-station tape machine roll tension adjustment mechanism, comprising: two rolls disposed inside the tape machine and limit rollers rotatably connected to the inner walls on both sides of the tape machine;

[0008] An adjustment assembly includes two adjustment rollers disposed inside the conveyor belt machine. The adjustment rollers are located below one side of the corresponding roll roller. Both ends of the adjustment rollers are rotatably connected to a slider. A first cylinder is fixedly connected to the surface of each slider. A disassembly assembly is provided between the roll roller and the conveyor belt machine.

[0009] Preferably, the sliders are slidably connected to the inner walls of both sides of the conveyor belt machine. The two upper first cylinders are positioned above the corresponding sliders, and the two lower first cylinders are positioned below the corresponding sliders. This drives the adjusting rollers to move up and down, thereby changing the tension of the conveyor belt.

[0010] Preferably, a second cylinder is disposed between the two first cylinders located on the same horizontal line, and both first cylinders are in communication with the second cylinder. The first cylinders are fixedly connected to the inner side wall of the conveyor belt, and the second cylinder is fixedly connected to the inner surface of the conveyor belt. This facilitates the adjustment of the pressure within the two first cylinders.

[0011] Preferably, a first piston is slidably connected to the inner wall of the first cylinder, one end of the first piston extends through the first cylinder and is fixedly connected to a slider, and a first spring is fixedly connected between the first piston and the inner wall of the first cylinder to balance the weight of the first piston.

[0012] Preferably, a second piston is slidably connected to the inner wall of the second cylinder, a second spring is fixedly connected between the second piston and the inner bottom wall of the second cylinder, and an air pump is fixedly connected to the surface of the conveyor belt, with the exhaust port of the air pump communicating with the second cylinder.

[0013] Preferably, the disassembly assembly includes a turntable rotatably connected to the inner wall of the conveyor belt machine, and a rotating shaft fixedly connected to one end of the roller, the rotating shaft being inserted into the inner wall of the turntable. This drives the roller to rotate.

[0014] Preferably, a positioning block is slidably connected to the inner wall of the other end of the roller, a rotating shaft is fixedly connected to the inner wall of the positioning block, and a third spring is fixedly connected between the positioning block and the inner wall of the roller. This facilitates disassembly.

[0015] The beneficial effects of this utility model are:

[0016] 1. By setting an adjusting roller on one side below the two rollers, and controlling the up and down sliding of the slider by the second piston in the first cylinder, and controlling the pressure in the first cylinder by the second cylinder, when it is necessary to adjust the tension of the tape machine roll, the pressure in the first cylinder can be adjusted by directly controlling the amount of gas injected into the second cylinder by the air pump. By observing the pressure in the first or second cylinder, the tension of the tape can be accurately controlled, reducing the difficulty of the workers' work.

[0017] 2. By installing multiple tape cores on two rollers and coordinating the two rollers, multiple tape cores can be wound simultaneously. This is suitable for large-diameter materials and can reduce the frequency of material changes. In addition, with the disassembly mechanism, multiple cores can be removed directly after the tape cores are finished and placed on a ready-to-roll roller for processing, reducing the time required to change tape cores and improving production efficiency.

Detailed Implementation

[0024] 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.

[0025] In practical implementation: such as Figure 1-5 As shown, a multi-station tape machine roll tension adjustment mechanism includes: two roll rollers 100 disposed inside the tape machine and limit rollers 200 rotatably connected to the inner walls on both sides of the tape machine.

[0026] The adjustment assembly 300 includes two adjustment rollers 310 disposed inside the conveyor belt machine. The adjustment rollers 310 are disposed below one side of the corresponding winding roller 100. Both ends of the adjustment rollers 310 are rotatably connected to sliders 311. The surfaces of the sliders 311 are fixedly connected to the first cylinder 320. A disassembly assembly 350 is provided between the winding roller 100 and the conveyor belt machine.

[0027] This device is installed inside the tape machine near the end. When the device is running, the tape substrate needs to be wound onto the starting roller at the starting position, then passed through two guide rollers on one side of the starting roller, then above the load-bearing roller, and then below the spraying roller. The tape substrate is coated here. The coated material will pass through the upper surface of the adjusting roller. Multiple sets of blades are set between the spraying roller and the adjusting roller to divide the substrate into multiple narrow tapes. These tapes are then passed alternately through two adjusting rollers 310 and then pasted onto multiple tape cores of the winding roller 100. The rotation of the rollers drives the tape substrate to move. The rollers are driven to rotate by a drive motor, which is set in the inner wall on both sides of the tape machine and fixedly connected to the turntable 353.

[0028] like Figure 1 , Figure 3 and Figure 4 As shown, sliders 311 are slidably connected to the inner walls of both sides of the tape machine. Two upper first cylinders 320 are positioned above the corresponding sliders 311, and two lower first cylinders 320 are positioned below the corresponding sliders 311. A second cylinder 330 is positioned between the two first cylinders 320 on the same horizontal line. Both first cylinders 320 are connected to the second cylinder 330. The first cylinders 320 are fixedly connected to the inner wall of the tape machine, and the second cylinders 330 are fixedly connected to the inner surface of the tape machine. A first piston 321 is slidably connected to the inner wall of the first cylinder 320. One end of the first piston 321 extends through the first cylinder 320 and is fixedly connected to the slider 311. A first spring 322 is fixedly connected between the first piston 321 and the inner wall of the first cylinder 320. A second piston 331 is slidably connected to the inner wall of the second cylinder 330. A second spring 332 is fixedly connected between the second piston 331 and the inner bottom wall of the second cylinder 330. An air pump 340 is fixedly connected to the surface of the conveyor belt machine. The exhaust port of the air pump 340 is connected to the second cylinder 330.

[0029] In this embodiment, pressure gauges are externally connected to the first cylinder 320 and the second cylinder 330. When adjusting the up and down movement of the adjusting roller 310, the lifting distance of the adjusting roller 310 can be accurately determined by observing the pressure gauges. The pistons of the two upper first cylinders 320 are set downwards, and the connection between the first cylinder 320 and the second cylinder 330 is located between the first piston 321 and the inner top wall. The pistons of the two lower first cylinders 320 are set upwards, and the connection between the first cylinder 320 and the second cylinder 330 is also located between the first piston 321 and the inner top wall. By setting a first spring 322 in the first cylinder 320, the first piston 321 can descend slowly when it descends, which makes it easier to observe the tension of the conveyor belt. At the same time, it can reduce the influence of the gravity of the first piston 321 during the adjustment process. Limiting rings are set in both the first cylinder 320 and the second cylinder 330 between the first piston 321 and the connecting cylinder to prevent the cylinder from losing its effect after the piston crosses the connecting point.

[0030] like Figure 1 , Figure 2 and Figure 4 As shown, the disassembly assembly 350 includes a turntable 353 rotatably connected to the inner wall of the conveyor belt machine, a rotating shaft 352 fixedly connected to one end of the roller 100, the rotating shaft 352 being inserted into the inner wall of the turntable 353, a positioning block 351 slidably connected to the inner wall of the other end of the roller 100, the rotating shaft 352 being fixedly connected to the inner wall of the positioning block 351, and a third spring 354 being fixedly connected between the positioning block 351 and the inner wall of the roller 100.

[0031] In this embodiment, when the tape core roll needs to be replaced, the positioning block 351 is pulled back to drive the rotating shaft 352 out of the turntable 353. Then, the other end is pulled out of the turntable 353, and the roll 100 with the tape core pre-installed is inserted into the turntable 353 in the same way.

[0032] When using this invention, to increase the tension of the tape, the air pump 340 is directly started, injecting gas into the upper part of the second cylinder 330, increasing the pressure inside the second cylinder 330. The second spring 332, in conjunction with the second piston 331, forces some of the gas injected into the second cylinder 330 into the first cylinder 320. The increased pressure inside the first cylinder 320 pushes the first piston 321 downward. By observing the pressure change inside the first cylinder 320, the distance the first piston 321 descends is determined, thereby determining the distance the adjusting roller 310 moves. The tension of the tape is changed by the pressure exerted by the adjusting roller 310 on the tape.

[0033] When it is necessary to reduce the tension of the tape, the air pump 340 draws the gas out of the second cylinder 330, thereby reducing the pressure in the second cylinder 330. The pressure difference draws the gas in the first cylinder 320 into the second cylinder 330, thereby reducing the pressure in the upper part of the first cylinder 320. The pressure difference in the first cylinder 320 pushes the first piston 321 to move upward, thereby driving the adjusting roller 310 to move up and down to reduce the tension of the tape.

[0034] It should be noted that the air pump 340, the first spring 322, the second spring 332 and the third spring 354 mentioned above are all devices with relatively mature existing technology. The specific model can be selected according to actual needs. At the same time, the air pump 340 can be powered by the built-in power supply or by the mains power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0035] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
