Description

Technical Field

[0001] The invention relates to the technical field of adhesive tape production equipment, and in particular to a deviation correction mechanism of an adhesive tape production machine. Background Art

[0002] In the tape production industry, the gluing process is a key link to ensure the quality of tape products. In the process of gluing tape, stable transmission of the tape is crucial. However, in actual production, due to factors such as mechanical vibration of production equipment, roller installation errors, uneven tension of tape materials or fluctuations in the thickness of the coating layer, the tape is prone to lateral deviation during high-speed transmission. If the deviation is not corrected in time, it will lead to problems such as uneven gluing, edge overflow or rewinding misalignment, which will seriously affect the product yield and subsequent processing performance.

[0003] From the perspective of product quality, tape deviation will lead to uneven glue coating. If the tape deviates to the left or right, the glue coating device cannot accurately and evenly apply glue on the tape, resulting in too much glue on one side of the tape and too little glue on the other side, which seriously affects the adhesive performance of the tape and reduces the qualified rate of the product. For example, in the production of packaging tape, uneven glue coating may cause the tape to have insufficient local adhesion when used, and it may not be able to firmly adhere to the items.

[0004] In terms of production efficiency, tape deviation frequently causes production interruptions. To ensure product quality, operators have to frequently stop the machine to adjust the tape position, which not only wastes a lot of time, but also increases labor costs. Moreover, restarting the production equipment takes a certain amount of time to reach a stable operating state, further reducing production efficiency. Summary of the invention

The setting of the driving device 38 provides a power source for the correcting member 3, so that the correcting action can be performed in a timely and effective manner. The driving device 38 can be an electric telescopic rod when in use.

[0028] Furthermore, the fixed plate 34 is provided with a linkage member 39, which includes a rotating plate 391, a rotating rod 392 and a fixed leg 395, the rotating rod 392 is rotatably connected to the rotating plate 391, the rotating rod 392 is arranged on the fixed plate 34, one end of the rotating plate 391 is rotatably connected to the connecting rod 351, the other end of the rotating plate 391 is provided with an arc-shaped toothed plate 393, the fixed leg 395 is provided with a reducer 394, the input shaft of the reducer 394 is provided with a gear meshing with the arc-shaped toothed plate 393, and the output shaft of the reducer 394 is provided with a gear meshing with the arc-shaped toothed plate 393.

The output shaft of the reducer 394 synchronously drives the ball nut 42 to rotate through the transmission assembly 396. The setting of the linkage member 39 realizes the linkage between the deviation correction member 3 and the adjusting member 4, so that the belt tension can be synchronously adjusted while correcting the deviation.

[0029] The rotating plate 391 is composed of a plate body 3911 and an insertion rod 3912. One end of the plate body 3911 is connected to the arc-shaped toothed plate 393. The other end of the plate body 3911 is provided with a slot. One end of the insertion rod 3912 is movably inserted into the slot. The other end of the insertion rod 3912 is provided with a connecting head 3913. The connecting head 3913 is rotatably connected to the connecting rod 351. The movable connection mode of the insertion rod 3912 in the slot enables the rotating plate 391 to be fine-tuned within a certain range when connected to the connecting rod 351. The movement of the insertion rod 3912 in the slot can buffer and absorb certain stress changes, thereby avoiding damage to components or poor movement due to rigid connection.

[0030] It should be noted that the adjusting member 4 includes a positioning plate 48, a rotating plate 47 and a sleeve 41. The positioning plate 48 is fixed on the gluing device 1. The rotating plate 47 is rotatably arranged on the positioning plate 48. A lifting member is arranged in the sleeve 41. The lifting member is rotatably connected to one end of the rotating plate 47. The end of the rotating plate 47 away from the lifting member is rotatably connected to a tension roller 410. The adjusting member 4 can be used to adaptively adjust the tension on both sides of the tape according to the situation.

[0031] It should be added that the lifting member includes a ball screw 43, on which a ball nut 42 is provided, and the ball nut 42 is rotatably arranged on the sleeve 41, and a transmission assembly 396 is connected to the ball nut 42, and the ball screw 43 is in the sleeve 41. A control block 45 is provided at the upper end of the ball screw 43, and the control block 45 is rotatably connected to the end of the rotating plate 2 47 away from the tension roller 410. When the transmission assembly 396 transmits power to the ball nut 42, the ball nut 42 rotates on the sleeve 41. Due to the cooperation between the ball nut 42 and the ball screw 43, the ball screw 43 performs precise lifting and lowering movements in the sleeve 41, and a pin 1 46 is provided at one end of the rotating plate 2 47 connected to the control block 45, and a movable hole is provided on the control block 45, and the pin 1 46 is in the movable hole. The rotating plate 2 47 and the positioning plate 48 are rotatably connected via the pin 2 49.

[0032] Among them, a limit plate 44 is provided at the lower end of the ball screw 43, a limit groove 411 is provided in the sleeve 41, and a limit end is provided on the limit plate 44, and the limit end moves in the limit groove 411. Through the cooperation between the limit plate 44 and the limit groove 411, the ball screw 43 can be limited to ensure that the ball screw 43 can move linearly up and down.

[0033] When the adhesive tape is being coated with glue, the deflection correction probe 23 detects the position of the edges of both sides of the conveyed adhesive tape when the adhesive tape is being transmitted on the coating device. When the adhesive tape deviates, the deflection correction probe 23 detects the deflection of the adhesive tape, and the driving device 38 is started. Taking the deflection of the adhesive tape to the left as an example, the output shaft of the driving device 38 extends out, and drives the connecting plate 35 to move to the right along the guide rod 37 through the control board 381. The connecting plate 35 pushes one end of the deflection correction wheel 31 to move to the right through the connecting block 32. Since both ends of the deflection correction wheel 31 are rotatably connected to the connecting plate 35 through the connecting block 32, and the connecting plate 35 at the other end has a certain degree of freedom of movement on the guide rod 37, the deflection correction wheel 31 moves to the right as a whole, and a rightward pulling force is generated on the adhesive tape, thereby pushing the adhesive tape to the right to achieve deflection correction. Conversely, when the adhesive tape deviates to the right, the output shaft of the driving device 38 retracts, drives the connecting plate 35 to move to the left, causes the deflection correction wheel 31 to move to the left, and pulls the adhesive tape to the left for deflection correction. When the deviation correcting member 3 corrects the deviation of the adhesive tape, the movement of the connecting plate 35 drives the rotating plate 1 391 to rotate through the connecting rod 351, and the arc-shaped toothed plate 393 at the other end of the rotating plate 1 391 rotates with the rotating plate 1 391, and the arc-shaped toothed plate 393 meshes with the gear on the input shaft of the reducer 394, driving the gear to rotate, thereby rotating the input shaft of the reducer 394, and after the reducer 394 changes the transmission ratio, its output shaft drives the ball nut 42 to rotate through the transmission assembly 396, and when the ball nut 42 rotates, the ball screw 43 moves up and down in the sleeve, and when the ball screw 43 rises, the control block 45 pulls or pushes the pin rod 1 46, thereby pulling or pushing the rotating plate 2 47 to rotate around the pin rod 2 49, so that the rotating plate 2 47 away from the end of the tension roller 410 rises or falls, and when the tension roller 410 falls, the tension of the corresponding side of the adhesive tape increases, and vice versa, when the tension roller 410 rises, the tension of the corresponding side of the adhesive tape decreases; When the tape deviates to the right, it means that the tension on the left side of the transmitted tape is small, and the tension roller 410 on the left side drops and is fine-tuned to increase the tension on the left side of the tape. At the same time, the tension roller 410 on the right side is in an upward state to reduce the tension on the right side of the tape. Conversely, when the tape deviates to the left, the tension roller 410 on the left side rises and is fine-tuned, and the tension roller 410 on the right side drops and is fine-tuned. The tension on both sides of the tape can be adaptively adjusted immediately while the tape is being corrected. This immediacy ensures that the tension can be adjusted accordingly at the moment the tape deviates, which helps the tape to quickly return to normal operating conditions, further improving production efficiency and product quality.

The purpose of the present invention has been fully and effectively achieved.
