Description

Technical Field

[0001] This utility model relates to the field of tape winding equipment technology, and in particular to a reel mechanism for an automatic winding machine. Background Technology

[0002] A winding machine is an automated mechanical device that winds bulk belts into reels of a certain outer diameter.

[0003] Publication No. CN215402124U discloses a tape wrapping machine, including a frame, a feeding mechanism mounted on the frame, a clamping mechanism and a wrapping mechanism mounted on the frame, a limiting mechanism and a pressing mechanism mounted on the frame, an adhesive applicator mounted on the frame, and an adhesive cutting mechanism mounted on the adhesive applicator. The feeding mechanism is located on one side of the frame, the clamping mechanism is located between the feeding mechanism and the wrapping mechanism, and the adhesive applicator includes an adhesive applicator drive assembly mounted on the frame, an adhesive tape assembly mounted on the adhesive applicator drive assembly, and an adhesive applicator component mounted on the adhesive tape assembly. One end of the adhesive applicator component is correspondingly disposed with respect to the wrapping mechanism. This type of strapping winding machine, through its feeding mechanism, clamping mechanism, winding mechanism, limiting mechanism, pressing mechanism, adhesive applicator, and adhesive cutting mechanism, enables fully automated strapping winding, greatly improving production efficiency. The adhesive applicator, pressing mechanism, and adhesive cutting mechanism work together to use adhesive tape to fix the outermost end of the strapping roll, providing a good fixation effect and preventing the strapping from becoming loose or damaged. However, there is a drawback, mainly in the cutting mechanism. The cutting mechanism uses a scissor structure as a cutting tool for the product strapping. However, considering the thickness and overall toughness of the product strapping, the combination of the scissor structure and the cylinder drive is prone to slippage during cutting. Slippage can lead to cutting failure or fraying at the end of the product strapping, resulting in an unsightly product strapping. Utility Model Content

[0004] This invention aims to overcome the shortcomings of the prior art by providing a reel mechanism for an automatic winding machine to solve the aforementioned problems.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: The winding mechanism of this automatic winding machine includes a machine body. The machine body is provided with a fixed plate and an adjustable pressure bar at the winding station. The longitudinal position of the fixed plate is not adjustable, and a winding shaft with a rotatable and adjustable longitudinal position is provided in the center. The winding shaft has an insertion port for the product belt to pass through. After the product belt passes through, the product belt is wound on the winding shaft by rotating the winding shaft. The adjustable pressure bar is located at the front end of the fixed plate and its longitudinal position is adjustable. The machine body is provided with a clamping unit located on the side of the adjustable pressure bar to guide the product belt to the winding shaft. The machine body is provided with a cutting unit located on the side of the clamping unit to cut the product belt by punching.

[0006] To further improve the design, the back of the adjustable pressure rod is equipped with a telescopic structure that allows the adjustable pressure rod to extend and retract in the longitudinal direction.

[0017] The present invention will be further described below with reference to the accompanying drawings:

[0018] Referring to the attached diagram: The winding mechanism of this automatic winding machine includes a body 1. The body 1 has a fixed plate 2 and an adjustable pressure bar 3 at the winding station. The longitudinal position of the fixed plate 2 is not adjustable, and a winding shaft 4 with a rotatable and adjustable longitudinal position is provided in the center. The winding shaft 4 has an insertion port 41 for the product belt to pass through. After the product belt passes through, the product belt is wound on the winding shaft 4 by rotation. The adjustable pressure bar 3 is located at the front end of the fixed plate 2 and its longitudinal position is adjustable. The body 1 is provided with a clamping unit 5 located on the side of the adjustable pressure bar 3 to guide the product belt to the winding shaft. The body 1 is provided with a cutting unit 6 located on the side of the clamping unit 5 to cut the product belt by punching. The principle of this utility model is that the fixed plate 2 is set on the machine body 1, and the winding shaft 4 is set on the machine body 1 at the center position. The winding shaft 4 can rotate and extend and retract. The rotation occurs after the product belt passes through the insertion port 41 of the winding shaft 4, so that the product belt is wound on the winding shaft 5 to realize the winding operation. The extension and retraction occur after the winding operation is completed, so that the belt reel is detached from the winding shaft 4, and the belt reel falls into the take-up component. The adjustable pressure rod 3 is used to cooperate with the fixed plate 2 by extension and retraction during the winding operation, so that it can be used as a lateral constraint for the belt reel during the take-up. The purpose of this is to make the belt reel regular and the take-up quality good. At the same time, the clamping unit 5 and the cutting unit 6 realize continuous winding action. Moreover, the punching cutting method will not slip (cutting failure) or cause the end of the product belt to fray (poor cutting effect) as in the prior art when cutting the product belt.

[0019] The adjustable pressure rod 3 has a telescopic structure on its back, allowing it to extend and retract longitudinally. This telescopic structure uses its own expansion and contraction to engage or disengage the adjustable pressure rod 3 from the fixed disc 2. Specifically, during winding, a gap matching the product strip width is formed between the adjustable pressure rod 3 and the fixed disc 2, allowing it to act laterally on the strip after it has been formed. During unwinding, a gap larger than the product strip width is formed between the adjustable pressure rod 3 and the fixed disc 2, releasing the lateral constraint on the strip and preventing it from obstructing the strip from entering the winding assembly. In this embodiment, the telescopic structure consists of a telescopic rod and a cylinder serving as a power source.

[0020] The clamping unit 5 includes a connecting rod 51, a support frame 52, a mounting plate 53, and two clamping arms 54 driven by cylinders. The connecting rod 51 moves along the extension direction of the product belt and is partially exposed outside the machine body 1. The support frame 52 is located at the end of the connecting rod 51 exposed outside the machine body 1. The mounting plate 53 is mounted on the support frame 52. The two clamping arms 54 are mounted on the mounting plate 53 by cylinders and are symmetrically distributed vertically so that they move synchronously and in the same direction when clamping or releasing the product belt. The connecting rod 51 moves through a slide rail slider structure. Part of it extends outside the body 1 to connect with the support frame 52. The support frame 52 provides a connection for the mounting plate 53, that is, it has an insertion cavity for the mounting plate 53 to be inserted into, and increases the working height of the clamping mechanism to adapt to the working height of the product belt. The mounting plate 53 also increases the working height of the clamping mechanism to adapt to the working height of the product belt, and is used to set the cylinder for driving the clamping arm 54. The output ends of the two cylinders are arranged opposite to each other, so that the two clamping arms 54 can move synchronously in the same direction when clamping or releasing the product belt.

[0021] The side of the mounting plate 53 is provided with an extension plate 53-a to increase the lateral width of the mounting plate 53. That is, the extension plate 53-a is also used to connect with the cylinder of the drive clamping arm 54. This allows the mounting plate 53 to be adapted to the lateral width of the cylinder, and the full connection can also increase the stability of the cylinder during use.

[0022] The cutting unit 6 includes an upper cutting connector 61 and a lower cutting connector 62. The upper cutting connector 61 is equipped with a cutting blade 61-a driven by a cylinder and located above the product belt. The lower cutting connector 62 is equipped with a support seat 62-a driven by a cylinder and located below the product belt. This allows the product belt to be clamped between the cutting blade 61-a and the support seat 62-a during cutting. The cutting blade 61-a cuts the product belt, while the support seat 62-a provides lower support for the product belt. The contact surface between the support seat 62-a and the product belt is flat, thus ensuring the product belt... The belt can be laid flat on it to ensure the cutting effect. In this way, the belt is cut in time after the belt reel is wound to the required outer diameter, so that the belt reel that has completed the winding operation is removed from the winding shaft 4 and automatically enters the winding operation of the next belt reel. This meets the needs of automated belt winding. At the same time, the support base 61 is also equipped with an ultrasonic generator, which is used to generate mechanical vibration energy. When the cutting blade 61-a cooperates with the support base 62-a for cutting, the cutting blade 61-a can generate high-frequency vibration force, thereby realizing the cutting of the product belt. This method makes the cutting efficiency high and the cutting effect good.

[0023] The cutting blade 61-a includes a connecting section 61-a1 and a cutting section 61-a2. The connecting section 61-a1 is mounted on the piston rod of the cylinder and has an assembly base surface 61-a11. An insert block 61-a111 is provided on the assembly base surface 61-a11. The cutting section 61-a2 has an assembly mating surface 61-a21 that contacts the assembly base surface 61-a11. An insert groove 61-a211 that engages with the insert block 61-a111 is provided on the assembly mating surface 61-a21. This configuration allows the cutting blade 61-a to be replaced, ensuring the sharpness of the cutting edge of the cutting blade 61-a and facilitating replacement, thanks to the engagement of the insert block 61-a111 and the insert groove 61-a211.

[0024] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
