Description

Technical Field

[0001] The utility model relates to a novel automatic deviation-correcting mechanism for a mesh belt. Background Art

[0002] The cold foil / laser transfer printing position is an endless belt wrapped roller group device, and the paper passes over the endless belt. The film and paper are pressed together by the embossing roller. When it reaches the peeling position, the film is recovered by the air expansion shaft roller, and the paper runs to the next station through the endless belt. Because the paper is sandwiched between the endless belt and the film, when the endless belt has a large error due to processing accuracy or installation accuracy, it will deviate left and right during operation, resulting in cold foil / transfer cracks, wrinkles and other process defects. Utility Model Content

[0003] In view of the technical problems existing in the background technology, the utility model aims to provide a novel automatic deviation correction mechanism for mesh belt, in which a motor is designed to drive the first eccentric sleeve to rotate, thereby driving the belt guide roller to rotate eccentrically, thereby realizing online deviation correction.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions: the new mesh belt automatic deviation correction mechanism comprises a mesh belt assembly, a detection assembly and a film belt, the mesh belt assembly comprises an endless belt and a belt guide roller, the endless belt is wound around the belt guide roller, a first eccentric sleeve is provided at one end of the belt guide roller, a second eccentric sleeve is provided at the other end of the belt guide roller, the first eccentric sleeve is transmission-connected to a motor, the motor drives the first eccentric sleeve to rotate, the detection assembly comprises an induction switch, the induction switch is used to detect the degree of left and right deviation of the endless belt, the induction switch is communicatively connected to a controller, and the controller is communicatively connected to the motor.

[0005] In this solution, the induction switch detects the degree of left-right deviation of the annular belt and sends a deviation signal to the controller. The controller controls the action of the motor according to the deviation signal. The motor drives the first eccentric sleeve to rotate, and adjusts the eccentric distance of the first eccentric sleeve to fine-tune the belt guide roller to balance the tension on both sides of the annular belt, thereby achieving non-stop adjustment. The first eccentric sleeve and the second eccentric sleeve can be stopped and adjusted synchronously to deal with the situation where the deviation of the annular belt exceeds the adjustment range.

[0006] Preferably, the endless belt is equipped with a tensioning roller, and the tensioning roller is movable and adjustable.

[0007] In this solution, synchronously adjusting the first eccentric sleeve and the second eccentric sleeve can change the overall tightness of the annular belt, and moving and adjusting the tensioning roller can stabilize the overall tightness of the annular belt.

[0008] Preferably, the motor is connected to an adjusting gear, the adjusting gear is meshed with a fan-shaped gear, the fan-shaped gear is connected to the first eccentric sleeve, and the fan-shaped gear is equipped with a position alarm switch.

[0009] In this solution, the sector gear is arranged such that the first eccentric sleeve will not continuously rotate beyond the adjustment range under the drive of the motor, avoiding excessive adjustment that exacerbates the left-right deviation of the endless belt. The position alarm switch can notify the operator to stop the machine for adjustment in a timely manner.

[0010] Preferably, induction brackets are arranged on both sides of the endless belt, and the induction switch is arranged on the induction bracket.

[0011] In this solution, induction switches are arranged on both sides of the endless belt to respectively sense the deviation degrees of the left and right sides of the endless belt.

[0012] Preferably, it further includes a film belt. A paper feeding channel is formed between the film belt and the endless belt. The paper feeding channel has a paper feeding inlet and a paper feeding outlet. The guide belt roller is arranged at the paper feeding inlet, and the induction switch is arranged at the paper feeding outlet.

[0013] In this solution, deviation correction is performed at the paper feeding inlet, and detection is performed at the paper feeding outlet to ensure the deviation correction effect.

[0014] Preferably, sliders are provided at both ends of the tension roller. The sliders are slidably arranged in the slide seats. The sliders are connected to the slide seats through disc springs, and the tension of the disc springs is adjustable.

[0015] In this solution, the tension of the disc springs is adjusted to drive the sliders and the tension roller to approach or move away from the endless belt, so as to control the tightness of the endless belt.

[0016] Preferably, the first eccentric sleeve is installed on the first wall panel through a composite sleeve, the second eccentric sleeve is installed on the second wall panel, and the first wall panel and the second wall panel are arranged opposite to each other.

[0017] In this solution, the setting of the composite sleeve enables the first eccentric sleeve not to affect its connection with the first wall panel when rotating, realizing on-line adjustment.

[0018] The beneficial effects of the present utility model are as follows: The induction switch detects the left-right deviation degree of the endless belt and sends the deviation signal to the controller. The controller controls the motor to act according to the deviation signal. The motor drives the first eccentric sleeve to rotate, adjusts the eccentricity of the first eccentric sleeve to balance the tensions on both sides of the endless belt, and realizes adjustment without stopping the machine. The first eccentric sleeve and the second eccentric sleeve can be adjusted synchronously when the machine is stopped to cope with the situation where the deviation degree of the endless belt exceeds the adjustment range. Therefore, the present utility model has substantial features and progress compared with the prior art. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] See attached Figures 1-3, in the embodiment of this implementation manner, a new type of automatic belt deviation rectifying mechanism includes a belt assembly 1, a detection assembly 7 and a film belt. The belt assembly 1 includes an endless belt 2 and a belt guiding roller 3. The endless belt 2 is wound around the belt guiding roller 3. One end of the belt guiding roller 3 is provided with a first eccentric sleeve 4. The first eccentric sleeve 4 is installed on a first wallboard 17 through a composite sleeve 16. The other end of the belt guiding roller 3 is provided with a second eccentric sleeve 5. The second eccentric sleeve 5 is installed on a second wallboard 18. The first wallboard 17 and the second wallboard 18 are arranged opposite to each other. The first eccentric sleeve 4 is drivingly connected to a motor 6. The motor 6 drives the first eccentric sleeve 4 to rotate. The detection assembly 7 includes an inductive switch 8. The inductive switch 8 is used to detect the left-right deviation degree of the endless belt 2. Inductive brackets are arranged on both sides of the endless belt 2. The inductive switch 8 is arranged on the inductive bracket. The inductive switch 8 is communicatively connected to a controller. The controller is communicatively connected to the motor 6. A paper feeding channel is formed between the film belt and the endless belt 2. The paper feeding channel has a paper feeding inlet and a paper feeding outlet. The belt guiding roller 3 is arranged at the paper feeding inlet. The inductive switch 8 is arranged at the paper feeding outlet.

[0028] In this implementation manner, the paper passes above the endless belt 2. The inductive switch 8 detects the left-right deviation degree of the endless belt 2 at the paper feeding outlet and sends the deviation signal to the controller. The controller controls the operation of the motor 6 according to the deviation signal. The motor 6 drives the first eccentric sleeve 4 to rotate, adjusts the eccentricity of the first eccentric sleeve 4 to finely adjust the unilateral position of the belt guiding roller 3, and balance the tensions on both sides of the endless belt 2. Among them, the first eccentric sleeve 4 and the second eccentric sleeve 5 can be adjusted synchronously during shutdown. The setting of the first eccentric sleeve 4 enables the belt guiding roller 3 to not only rotate with the endless belt 2 but also eccentrically rotate to rectify the deviation of the endless belt 2.

[0029] In other alternative implementation manners, the second eccentric sleeve 5 can also be adjusted online.

[0030] See Appendix Figures 2-3 , the endless belt 2 is equipped with a tensioning roller 10. Both ends of the tensioning roller 10 are provided with sliders 13. The sliders 13 are slidably arranged in slide seats 14. The sliders 13 are connected to the slide seats 14 through disc springs 15. The tension of the disc springs 15 can be adjusted. The motor 6 is connected to an adjusting gear 11. The adjusting gear 11 meshes with a sector gear 12. The sector gear 12 is connected to the first eccentric sleeve 4. The sector gear 12 is equipped with a position alarm switch.

[0031] In this embodiment, when the sector gear 12 reaches the position limit, the position alarm switch will alarm in time. The operator stops the machine and synchronously adjusts the first eccentric sleeve 4 and the second eccentric sleeve 5, and resets the sector gear 12. During the synchronous adjustment, by adjusting the tension of the disc spring 15, the slider 13 drives the tension roller 10 to move relative to the slide base 14, away from or close to the endless belt 2, so as to adjust the tightness of the endless belt 2. Among them, the disc spring 15 can be connected to the slide base 14 through a screw rod, and the tension of the disc spring 15 is adjusted by adjusting the screw rod.
