[0024] DETAILED DESCRIPTION

[0025] ​​​The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Example: This invention provides a coating tension control system, such as... Figures 1-4 As shown, the device includes a swing rod 3, a support rotating seat 4, a vertical guide sliding mechanism 5, a locking plate 6, a positioning and unlocking mechanism 7, and a support rod 2 for supporting the coating 1. The support rod 2 is rotatably mounted on one end of the swing rod 3, and a counterweight mechanism 8 is provided at the other end of the swing rod 3. The tension applied to the coating 1 by the support rod 2 can be changed by adjusting the weight of the counterweight mechanism 8. The middle part of the swing rod 3 is rotatably mounted on the support rotating seat 4, and the support rotating seat 4 is vertically slidably mounted on the vertical guide sliding mechanism 5. The locking plate 6 is inserted into the vertical guide sliding mechanism 5 and forms a shape with the vertical guide sliding mechanism 5. The card plate 6 is fixedly installed on the positioning and unlocking mechanism 7. The positioning and unlocking mechanism 7 is connected to the swing rod 3 and is fixedly installed on the support rotating base 4. A distance sensor for sensing the rotation angle of the swing rod 3 is fixedly installed on the support rotating base 4. The sensing end of the distance sensor is aligned with the swing rod 3. When the swing rod 3 rotates, the distance sensor will sense the change in position and transmit the signal to the controller. The controller controls the feeding end for conveying the coating 1 to speed up the conveying speed so that the swing rod 3 rotates back to the initial position.

[0027] When the feeding end used to transport coating 1 gets stuck, the winding end used to rewind coating 1 continues to work. Due to the high-speed winding of the coating, the support roller 2 will be pulled down to the limit position instantly, and the swing rod 3 will rotate to the final position. During the rotation of the swing rod 3, the positioning and unlocking mechanism 7 will be driven to rotate. The positioning and unlocking mechanism 7 will pull the clamping plate 6 to the final position, so that the clamping plate 6 will be separated from the vertical guide mechanism 5. The support rotating seat 4 will slide down along the vertical guide mechanism 5, so that the support roller 2 will also slide down. That is, during the jamming process, more reaction time is given to the equipment to avoid the coating 1 from breaking.

[0028] like Figure 5 and Figure 6As shown in the figure, the positioning unlocking mechanism 7 includes horizontal extension mechanism 7a, sliding plate 7b and at least two guide posts 7c, the swing rod 3 includes the rotating shaft 3a, the rotating shaft 3a is in transmission connection with one end of the horizontal extension mechanism 7a, it is conceived that the number of the rotating shaft 3a and the horizontal extension mechanism 7a is two, and they are symmetrically arranged, which can more smoothly push the sliding plate 7b to slide horizontally along the guide post 7c, the other end of the horizontal extension mechanism 7a is in transmission connection with the sliding plate 7b, and the horizontal extension mechanism 7a is fixedly installed on the support rotating seat 4; the sliding plate 7b is slidably installed on the two guide posts 7c; one end of the clamping plate 6 is fixedly installed on the sliding plate 7b;

[0029] When the swing rod 3 drives the support stick 2 to swing downward, the rotating shaft 3a will push the clamping plate 6 away from the vertical guide sliding mechanism 5 through the horizontal extension mechanism 7a, when the sliding plate 7b is pushed, the sliding plate 7b will slide horizontally along the guide post 7c, when the support stick 2 swings downward to the final position, the clamping plate 6 will be separated from the clamping connection with the vertical guide sliding mechanism 5. Conversely, when the swing rod 3 drives the support stick 2 to swing upward, the horizontal extension mechanism 7a will push the clamping plate 6 close to the vertical guide sliding mechanism 5.

[0030] As shown in the figure, Figure 5 and Figure 6 The horizontal extension mechanism 7a includes a driving gear 7a1, a reversing gear 7a2 and a rack 7a3, the driving gear 7a1 is fixedly installed on the rotating shaft 3a, the reversing gear 7a2 is rotatably installed on the support rotating seat 4 through the rotating seat, and the rack 7a3 is fixedly installed on the sliding plate 7b; the reversing gear 7a2 is in meshing connection with the driving gear 7a1 and the rack 7a3. When the support stick 2 swings downward, the rotating shaft 3a will inevitably rotate counterclockwise, so that the driving gear 7a1 rotates counterclockwise and the reversing gear 7a2 rotates clockwise, and the reversing gear 7a2 will drive the rack 7a3 to move through the meshing, that is, drive the clamping plate 6 away from the vertical guide sliding mechanism 5, when the support stick 2 moves to the final position, the clamping plate 6 will be separated from the clamping connection with the vertical guide sliding mechanism 5.

[0031] As shown in the figure, Figure 6 The vertical guide sliding mechanism 5 includes a guide plate 5b, a limiting support plate 5c and at least two guide posts 5a, each guide post 5a is vertically slidably installed on the guide plate 5b, realizing the vertical sliding of the support rotating seat 4, the bottom of each guide post 5a is fixedly connected with the support rotating seat 4, and the top of each guide post 5a is fixedly connected with the limiting support plate 5c, when the support rotating seat 4 falls, the limiting support plate 5c and the guide plate 5b are in contact, realizing the support and limitation of the support rotating seat 4, avoiding the phenomenon of disengagement, when the support stick 2 is in the initial position, the clamping plate 6 is inserted into the top of the guide plate 5b, realizing the clamping connection between the clamping plate 6 and the vertical guide sliding mechanism 5. The guide plate 5b is fixed on the equipment through the square tube.

[0032] As shown in the figure, Figure 4As shown, the top of the guide plate 5b is fixed with a limiting post 10, and the outer edge of the limiting post 10 is sleeved with a buffer spring 9. When the limiting support plate 1 5c extrudes the buffer spring 9, the buffer spring 9 is used to exert an elastic force vertically upward on the limiting support plate 1 5c. The number of limiting posts 10 and buffer springs 9 can be multiple groups. After the clamping between the clamping plate 6 and the vertical guide sliding mechanism 5 is separated, the limiting support plate 1 5c will fall. The buffer spring 9 buffers the limiting support plate 1 5c to avoid rigid collision.

[0033] As shown in the drawings, Figure 7 The support rotating seat 4 is fixedly provided with a limiting stop post 11, which is used to support the initial position of the swing rod 3. Through the support of the limiting stop post 11, the support stick 2 can have an initial position.

[0034] As shown in the drawings, Figure 8 The counterweight mechanism 8 includes a rotating sleeve 8a and a counterweight block 8b. The rotating sleeve 8a is rotatably installed on the swing rod 3, and the counterweight block 8b is fixedly installed on the rotating sleeve 8a. The swing rod 3 is fixedly provided with a support shaft connected with the rotating sleeve 8a, and the rotating sleeve 8a is sleeved in the support shaft, so that the rotating sleeve 8a can rotate. When the angle of the swing rod 3 changes, the counterweight block 8b can always maintain a vertical state, and can maintain a constant upward pulling force on the support stick 2.

[0035] As shown in the drawings, Figure 8 The counterweight block 8b is fixedly provided with a plurality of detachable disassembly blocks 8c. The disassembly blocks 8c are fixedly connected with the counterweight block 8b through screws. When disassembly is needed, the screws are unscrewed to complete the disassembly of the disassembly blocks 8c. By disassembling the disassembly blocks 8c, the upward pulling force on the support stick 2 is changed, that is, the tension on the coating 1 is changed, which meets the demand of tension adjustment.

[0036] The end of the guide post 1 7c away from the vertical guide sliding mechanism 5 is provided with a limiting plate 7d. By providing the limiting plate 7d, when the support rotating seat 4 falls, the sliding plate 7b will not slide out of the guide post 1 7c.

[0037] Working principle: when the winding speed of the coating 1 is greater than the unwinding speed, the tension of the coating 1 will increase, so that the support stick 2 is pulled downward, and the support stick 2 drives the swing rod 3 to rotate along the hinge of the support rotating seat 4 to balance the tension. When the swing rod 3 rotates, the distance sensor will sense the change of position and transmit the signal to the controller. The controller controls the feeding end for conveying the coating 1 to speed up the conveying speed, so that the swing rod 3 rotates to the initial position.

[0038] When the feeding end for conveying coating 1 is stuck, but the winding end for winding coating 1 is still working, and due to the high speed of coating winding, the support rod 2 will be pulled down to the limit position instantaneously, as shown in Figure 5 When the support rod 2 swings downward, the rotating shaft 3a will rotate counterclockwise, so that the driving gear 7a1 rotates counterclockwise and the reversing gear 7a2 rotates clockwise. The reversing gear 7a2 will drive the rack 7a3 to move by meshing, that is, drive the clamping plate 6 away from the vertical guide sliding mechanism 5, as shown in Figure 6 When the support rod 2 moves to the final position, the clamping plate 6 will be separated from the clamping of the vertical guide sliding mechanism 5, so that the support rotating seat 4 slides vertically through the guide column 5a and the guide plate 5b, giving the device more reaction time to avoid the breakage of the coating 1. When sliding to the bottom final position, the limiting support plate 1 5c collides with the buffer spring 9, reducing the impact force generated when colliding.

[0039] The coating tension control system can automatically adjust when the coating tension changes slightly by the counterweight mechanism and the distance measuring sensor. When the support rod moves to the final position in the stuck condition, the clamping plate is separated from the clamping of the vertical guide sliding mechanism, and the support rotating seat can quickly fall, releasing the support of the coating, giving the device reaction time to stop.

[0040] Obviously, those skilled in the art can make various modifications and variations to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalent technologies, the present application also intends to include these modifications and variations.
