Description

Technical Field

[0001] The utility model relates to the technical field of film material transmission, in particular to a film material transmission device. Background Art

[0002] In the printing, packaging, coating and patterning industries, in order to improve production efficiency and product quality, a roll-to-roll transmission mechanism for film materials is needed. This mechanism is a device used to transmit roll-shaped films, foils or paper materials on the production line. The transmission mechanism is usually composed of components such as conveyor rollers, tensioning devices, positioning guides and drive devices. The roll-to-roll transmission mechanism for film materials can transport roll-shaped materials such as films, foils or paper from one end to the other, ensuring the continuity and stability of the materials during the production process.

[0003] However, in some specific application scenarios, the film material needs to reciprocate, and the starting point position needs to be precisely controlled for each reciprocation. If a roll-to-roll motor drive is used, it is difficult to control the tension of the film material. At this time, the positioning of the film material needs to be achieved by adding a visual sensor, which complicates the structure of the overall mechanism and increases the equipment cost.

[0004] Therefore, there is an urgent need for a film material transmission device which not only has a simple structure but also can realize reciprocating motion while maintaining a constant tension of the film material. Utility Model Content

[0005] The utility model aims to provide a film material transmission device to solve the problem that the tension of the film material cannot be guaranteed to be constant when the film material reciprocates.

[0006] To achieve this purpose, the utility model adopts the following technical solutions:

[0011] Preferably, the first tensioning mechanism further comprises a first guide member, the first guide member is arranged in a vertical direction, the first floating roller is slidably connected to the first guide member, and / or the second tensioning mechanism further comprises a second guide member, the second guide member is arranged in a vertical direction, the second floating roller is slidably connected to the second guide member.

[0012] Preferably, the first floating roller can drive the film material at the first floating roller to slide downward along the first guide member under the action of gravity, and / or the second floating roller can drive the film material at the second floating roller to slide downward along the second guide member under the action of gravity.

[0013] Preferably, both ends of the first guide member and / or the second guide member are provided with limit members.

[0014] Preferably, the first floating roller is arranged on a first connecting frame, which is slidably connected to the first guide member, and / or the second floating roller is arranged on a second connecting frame, which is slidably connected to the second guide member.

[0019] Beneficial effects of the utility model:

[0020] The utility model discloses a film material transmission device, which is provided with a clamping mechanism, a first tensioning mechanism and a second tensioning mechanism. A first guide roller is provided between the clamping mechanism and the first tensioning mechanism and the second tensioning mechanism. The first floating roller and the second floating roller are in contact with one side of the film material, and the first guide roller is in contact with the other opposite side of the film material. Therefore, when the clamping mechanism clamps the film material and moves it at a constant speed from the first tensioning mechanism toward the second tensioning mechanism, the film material also moves at a constant speed. Therefore, the film material drives the first floating roller to rise at a constant speed, and the second floating roller drives the film material to fall at a constant speed. Conversely, when the clamping mechanism clamps the film material and moves it at a constant speed from the second tensioning mechanism toward the first tensioning mechanism, the film material drives the second floating roller to rise at a constant speed, and the first floating roller drives the film material to fall at a constant speed. During this process, the clamping mechanism drives the film material to move at a constant speed between the first tensioning mechanism and the second tensioning mechanism, and the first and second floating rollers will also move at a constant speed, thereby achieving a constant tension of the film material during the reciprocating motion; at the same time, due to the constant tension effect of the first and second floating rollers, it can effectively ensure that the clamping mechanism clamps the film material from the first position to the second position, and during the entire reciprocating motion process from the second position back to the first position, the position of the film material abutted by the second guide roller remains unchanged, thereby achieving high repeatability positioning accuracy of local film material in the process section without affecting the entire film material transmission position.

[0021] In addition, the film material transmission device of the present invention is also provided with a floating roller limiting mechanism, which can easily and accurately complete the initial position positioning of the first and second floating rollers, thereby improving the transmission efficiency.

[0038] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0039] Embodiment 1

[0040] like Figure 1 and Figure 2 As shown, this embodiment provides a film material transmission device, when the device transmits the film material 40, the local film material 40 needs to reciprocate. The device mainly includes a clamping mechanism 10, a first tensioning mechanism 20 and a second tensioning mechanism 30. Among them, the clamping mechanism 10 can clamp the film material 40 and drive the local film material 40 to reciprocate; the clamping mechanism 10 is arranged between the first tensioning mechanism 20 and the second tensioning mechanism 30, and a first guide roller 50 is arranged between the first tensioning mechanism 20, the second tensioning mechanism 30 and the clamping mechanism 10; the first tensioning mechanism 20 includes a first floating roller 22, and the second tensioning mechanism 30 includes a second floating roller 32, and the first floating roller 22 and the second floating roller 32 are used to abut against one side of the film material 40.

[0041] It is worth noting that in this embodiment, the film material 40 is a thin film, and the film material 40 needs to reciprocate between the two first guide rollers 50. Therefore, in this embodiment, the clamping mechanism 10 is used to clamp the film material 40 to reciprocate between the first tensioning mechanism 20 and the second tensioning mechanism 30. In addition, in order to ensure that the tension on the film material 40 remains unchanged during the movement, the movement of the clamping mechanism 10 in the direction of clamping the film material 40 from the first tensioning mechanism 20 to the second tensioning mechanism 30 is a uniform movement, so the film material 40 will drive the first floating roller 22 to rise at a uniform speed, and the second floating roller 32 will drive the film material 40 to fall at a uniform speed; conversely, when the clamping mechanism 10 clamps the film material 40 and moves at a uniform speed from the second tensioning mechanism 30 to the first tensioning mechanism 20, the film material 40 drives the second floating roller 32 to rise at a uniform speed, and the first floating roller 22 drives the film material 40 to fall at a uniform speed. In this process, since the clamping mechanism 10, the film material 40, the first floating roller 22 and the second floating roller 32 are all moving at a uniform speed, according to Newton's first law, the resultant external force on an object is zero when it is stationary or in a uniform motion state. In this embodiment, preferably, the first floating roller 22 and the second floating roller 32 are both arranged above the film material 40, and the first floating roller 22 and the second floating roller 32 rise or fall at a uniform speed under the combined force of their own weight and the tension of the film material 40, that is, the gravity on the first floating roller 22 and the second floating roller 32 is balanced with the tension on the film material 40, and the tension on the film material 40 on the left and right sides of the first floating roller 22 and the second floating roller 32 is respectively one-half of the weight of the first floating roller 22 and the second floating roller 32, and remains unchanged during the reciprocating motion, thereby realizing the control of the tension of the local film material 40 during the reciprocating motion. It is further explained that the clamping mechanism 10 can be any pneumatic clamp as long as it can ensure that the film material 40 will not be damaged during the process of clamping the film material 40, and there is no limitation on this.

[0042] In this embodiment, if Figure 1 and Figure 2 As shown, along the vertical direction, the two first guide rollers 50 are at the same level. By making the two first guide rollers 50 at the same level, it can be ensured that the direction of the clamping mechanism 10 clamping the film material 40 at a constant speed is also horizontal, so it is convenient to set the equipment used in conjunction with the reciprocating motion of the film material 40, thereby simplifying the overall structure, reducing the manufacturing cost, and ensuring a good reciprocating motion effect.

[0043] To ensure that the first floating roller 22 and the second floating roller 32 can both rise and fall in the vertical direction, Figure 1 and Figure 2 As shown, the first tensioning mechanism 20 also includes a first guide member 21, which is arranged in the vertical direction, and the first floating roller 22 is slidably connected to the first guide member 21, and / or the second tensioning mechanism 30 also includes a second guide member 31, which is arranged in the vertical direction, and the second floating roller 32 is slidably connected to the second guide member 31.

[0044] It is worth mentioning that, in the present embodiment, the first guide member 21 and the second guide member 31 are provided at the same time. By providing the first guide member 21 and the second guide member 31, it is possible to ensure that the first floating roller 22 and the second floating roller 32 always maintain a vertical direction during the rising or falling process, and will not swing left and right during the rising or falling process; at the same time, since the first floating roller 22 and the second floating roller 32 are respectively slidably connected to the first guide member 21 and the second guide member 31, the resistance generated by the first guide member 21 and the second guide member 31 to the first floating roller 22 and the second floating roller 32 can be minimized, thereby ensuring that when the film material 40 drives the first floating roller 22 or the second floating roller 32 to rise, the friction resistance is negligible, and the film material 40 no longer needs to overcome the friction resistance, thereby further ensuring that the tension of the film material 40 remains unchanged during the reciprocating motion.

[0045] In addition, it is further explained that, since the first floating roller 22 is slidably connected to the first guide 21, and / or the second floating roller 32 is slidably connected to the second guide 31, and the friction resistance during the sliding process is negligible. Therefore, the first floating roller 22 can drive the film material 40 at the first floating roller 22 to slide downward along the first guide 21 under the action of gravity, and / or the second floating roller 32 can drive the film material 40 at the second floating roller 32 to slide downward along the second guide 31 under the action of gravity. In this embodiment, the first floating roller 22 and the second floating roller 32 are slidably connected to the first guide 21 and the second guide 31 respectively. This arrangement can use the self-weight of the first floating roller 22 and the second floating roller 32 when the first floating roller 22 and the second floating roller 32 move up and down in the vertical direction without the help of other devices, thereby simplifying the overall structure of the device, reducing the manufacturing and use costs, and being simple and convenient.

[0046] To ensure that the first floating roller 22 and the second floating roller 32 will not separate from the first guide member 21 and the second guide member 31 during the rising or falling process, Figure 1 and Figure 2 As shown, both ends of the first guide member 21 and / or the second guide member 31 are provided with a limit member 80. In this embodiment, both ends of the first guide member 21 and the second guide member 31 are provided with a limit member 80. By providing the limit member 80, it can be ensured that when the first floating roller 22 is about to be separated from the top end or the bottom end of the first guide member 21, the limit member 80 can abut against the first floating roller 22, thereby limiting the first floating roller 22 from continuing to rise or fall, thereby ensuring a good use effect. In addition, the limit member 80 also has a limiting effect on the second floating roller 32, which will not be described in detail here.

[0047] Considering that it is inconvenient to install the first floating roller 22 and the second floating roller 32 on the first guide member 21 and the second guide member 31, as shown in FIG. Figure 1-Figure 3 As shown, the first floating roller 22 is arranged on the first connecting frame 23, and the first connecting frame 23 is slidably connected to the first guide member 21, and / or the second floating roller 32 is arranged on the second connecting frame 33, and the second connecting frame 33 is slidably connected to the second guide member 31. In this embodiment, the first floating roller 22 and the second floating roller 32 are slidably connected to the first guide member 21 and the second guide member 31 through the first connecting frame 23 and the second connecting frame 33, respectively. By providing the first connecting frame 23 and the second connecting frame 33, it is not only convenient to install the first floating roller 22 and the second floating roller 32, but also when maintenance is needed later, it is only necessary to directly remove the first floating roller 22 or the second floating roller 32 from the first connecting frame 23 or the second connecting frame 33, which is simple and convenient to operate.

[0048] like Figure 1 and Figure 2As shown, the first tensioning mechanism 20 and the second tensioning mechanism 30 are both provided with a second guide roller 60 on the side away from the first guide roller 50, the first floating roller 22 and the second floating roller 32 are used to abut against one side of the film material 40, and the second guide roller 60 is used to abut against the other side of the film material 40, so that the film material 40 is tensioned. In addition, to ensure a good use effect, the first guide roller 50 and the second guide roller 60 are both at the same level. By providing the second guide roller 60, the film material 40 can be guided before the film material 40 abuts against the first floating roller 22, and the film material 40 can be guided out after the film material 40 abuts against the second floating roller 32, so that it is convenient to transfer the film material 40 to the next station after the film material 40 reciprocates.

[0049] Embodiment 2

[0050] After the film material 40 completes the reciprocating motion, the film material 40 needs to be transferred to the next station. Figure 1 and Figure 3 As shown, the film material transmission device further includes a floating roller limiting mechanism 70 , and the floating roller limiting mechanism 70 is configured to limit the movement of the first floating roller 22 and / or the second floating roller 32 when the film material 40 is transmitted.

[0051] It is worth noting that, in the present embodiment, the floating roller limiting mechanism 70 is a telescopic cylinder. In the closed state, the output end of the telescopic cylinder retracts, and the first floating roller 22 or the second floating roller 32 can slide on the first guide 21 or the second guide 31; in the open state, the output end of the telescopic cylinder extends, and at this time, the first floating roller 22 or the second floating roller 32 cannot rise or fall along the first guide 21 or the second guide 31. In other embodiments, the floating roller limiting mechanism 70 can also use a telescopic motor. In the closed state, the output end of the telescopic motor retracts, and in the open state, the output end of the telescopic motor extends; in addition, a braking device can also be used, and the braking device can directly lock the first floating roller 22 and the second floating roller 32 on the first guide 21 and the second guide 31, as long as it can be ensured that the first floating roller 22 and the second floating roller 32 will not move up and down when the film material 40 is transmitted.

[0052] It is further explained that, in this embodiment, the initial state of the film material transmission device 40 is as follows: Figure 1As shown in the figure (the first floating roller 22 is located at the bottom of the first guide member 21, and the second floating roller 32 is located at the top of the second guide member 31), so at the moment of starting transmission, the tension of the film material 40 will cause the first floating roller 22 to move upward along the first guide member 21 (the second floating roller 32 also moves upward along the second guide member 31). Therefore, the floating roller limiting mechanism 70 is only provided above the initial position of the first floating roller 22, and when the film material 40 needs to be transmitted, the floating roller limiting mechanism 70 is opened, and its output end extends out, thereby limiting the upward movement of the first floating roller 22. During the transmission process, the film material 40 is always in a tensioned state, and the speed of transmitting the film material 40 at the left and right ends of the film material transmission device is the same, so the second floating roller 32 can also remain stationary at the initial position and will not move up and down. Therefore, only one floating roller limiting mechanism 70 is required to solve the problem of the first floating roller 22 and the second floating roller 32 shaking up and down during the transmission process, and after the transmission of the film material 40 is completed, the first floating roller 22 and the second floating roller 32 can still maintain the initial position, so there is no need to reposition the first floating roller 22 and the second floating roller 32, thereby simplifying the structure and reducing the manufacturing cost.

[0053] Finally combined Figure 1 and Figure 2 Describe the use process of the film material transmission device:

[0054] First, if Figure 1 and Figure 2 When the partial film material 40 reciprocates, the first floating roller 22 and the second floating roller 32 can float driven by the film material 40, and the clamping mechanism 10 clamps the film material 40 and drives the partial film material 40 to reciprocate at a uniform speed between the first tensioning mechanism 20 and the second tensioning mechanism 30;

[0055] Secondly, when the film material 40 is transmitted, the clamping mechanism 10 releases the film material 40 and opens the floating roller limiting mechanism 70 in the film material transmission device. The floating roller limiting mechanism 70 can extend the output end to limit the movement of the first floating roller 22 and the second floating roller 32 in the vertical direction, and drive the film material 40 to pass through the first tensioning mechanism 20, the first guide roller 50 and the second tensioning mechanism 30 in sequence, so that the film material 40 is transmitted to the corresponding station. It should be noted that the film material transmission drive mechanism can be used to drive the film material 40 to be transmitted to the corresponding station as a whole, such as the winding mechanism set on the rear side, which is not specifically limited here, as long as the overall movement of the film material 40 can be achieved.

[0056] In summary, the use of the above-mentioned film material transmission device can not only solve the problem that the tension of the film material 40 cannot be guaranteed to remain unchanged when the film material 40 reciprocates; it can also ensure that during the transmission of the film material 40, the first floating roller 22 and the second floating roller 32 will not move up and down, and there is no need to reposition them after the transmission is completed; and the operation process is simple and convenient, and the transmission efficiency is high.

[0057] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
