Description

Technical Field

[0001] This utility model relates to the field of dressing processing technology, and in particular to a dressing cutting device. Background Technology

[0002] In existing technologies, the adhesive tape is applied to a release liner before the adhesive patch is cut. Currently, the pressure between the cutting blade and the conveyor platform in the cutting device is fixed. After prolonged use, this pressure becomes unstable, affecting cutting performance and causing burrs on the cut edges of the patch, thus impacting product quality. Utility Model Content

[0003] To address the aforementioned technical deficiencies, this invention provides a dressing and cutting device that can effectively adjust the cutting pressure to ensure reliable cutting and high-quality dressing products.

[0004] This utility model discloses a dressing cutting device, including a conveying platform, vertically upward columns on both sides of the conveying platform, upwardly extending studs at the upper end of the columns, a crossbeam at the top of the two studs, an adjusting nut seat on the stud, a guide seat rotatably mounted on the adjusting nut seat, a guide hole on the guide seat, a guide post inside the guide hole, a shaft seat at the bottom of the guide post, a compression spring on the guide post between the shaft seat and the guide seat, a cutting shaft rotatably mounted between the two shaft seats, a drive motor fixedly mounted on one end of the shaft seat, the drive motor being connected to the cutting shaft, and a plurality of circular cutting blades spaced apart on the cutting shaft.

[0005] The outer wall of the adjusting nut seat is circular, and an annular limiting groove is provided on the outer wall of the adjusting nut. A through hole consistent with the outer wall of the adjusting nut seat is provided on the guide seat, and an annular limiting protrusion is provided on the inner wall of the through hole. The adjusting nut seat is sleeved inside the through hole, and the annular limiting protrusion is fitted into the annular limiting groove.

[0006] Several outwardly inclined support rods are arranged in a circumferentially spaced array on the upper side of the adjusting nut seat. The tops of all the support rods on the same adjusting nut seat are fixedly connected by a connecting ring to form an adjusting handle.

[0007] The cutting shaft has five circular cutting blades, one of which is fixed in the middle of the cutting shaft and is called the fixed cutting blade. Two circular cutting blades are slidably sleeved on the cutting shaft on both sides of the fixed cutting blade and are called movable cutting blades. Two screws are fixed on both sides of the fixed cutting blade. Two screws are also provided on the movable cutting blade near the fixed cutting blade. Two through holes are provided on each movable cutting blade. The through holes on the movable cutting blade are inserted into the corresponding screws. Locking nuts are provided on the screws on both sides of the movable cutting blade.

[0008] The screws on the fixed and movable cutting blades are evenly spaced along the circumference, with the screws on the movable cutting blades spaced 180° apart and the screws on the fixed cutting blades spaced 180° apart.

[0009] The present invention provides a dressing cutting device that adjusts the height of the guide seat by adjusting the nut seat, thereby changing the pressure of the compression spring on the shaft seat. This allows for adjustment of the cutting pressure of the circular cutting blade on the dressing, greatly improving the cutting quality. At the same time, the cutting spacing can be stably adjusted to adapt to the cutting of dressings of different sizes, making it highly versatile. Attached Figure Description

[0015] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0016] Example 1:

[0017] like Figures 1-5As shown, this utility model discloses a dressing cutting device, including a conveying platform 1, vertically upward columns 2 on both sides of the conveying platform 1, an upwardly extending stud 3 at the upper end of the column 2, a crossbeam 4 at the top of the two studs 3, an adjusting nut seat 5 on the stud 3, a guide seat 6 rotatably mounted on the adjusting nut seat 5, a guide hole on the guide seat 6, a guide post 9 in the guide hole, a shaft seat 10 at the bottom of the guide post 9, a compression spring 11 on the guide post 9 between the shaft seat 10 and the guide seat 6, a cutting shaft 14 rotatably mounted between the two shaft seats 10, a drive motor 12 fixedly mounted on one end of the shaft seat 10, the drive motor 12 being connected to the cutting shaft 14, and a plurality of circular cutting blades 13 spaced apart on the cutting shaft 14.

[0018] The conveyor platform 1 is an existing application and cutting platform, which can be a flat plate structure. A winding roller provides power to move the application on the conveyor platform 1, while a circular cutting blade 13 performs the cutting. Alternatively, the conveyor platform 1 can be a conveyor belt, on which the application is laid, and the conveyor belt drives the application to move synchronously and achieve cutting. Therefore, the conveyor platform 1 is a known existing structure and will not be described in detail or limited here. Columns 2 are set on both sides of the conveyor platform 1, and vertically upward studs 3 are set on the columns 2. The columns 2 are the mounting carriers for the studs 3, and the shape, size, and height of the two studs 3 are known. A crossbeam 4 is set on the top of the studs 3 to ensure stable fixing and stronger load-bearing capacity. An adjusting nut seat 5 is set on the stud 3, and the position of the adjusting nut seat 5 can be changed during rotation. A guide seat 6 is rotatably set outside the adjusting nut seat 5; that is, the guide seat 6 and the adjusting nut seat 5 are rotatably connected, and only rotatably connected, with no axial displacement between them. The guide seat 6 has a vertical guide hole, with a guide post 9 slidably connected inside. A shaft seat 10 is located at the bottom of the guide post 9. A compression spring 11 applies downward pressure to the shaft seat 10, thereby changing the cutting pressure of the circular cutting blade 13 on the cutting shaft 14 on the shaft seat 10 on the adhesive applied to the conveyor platform 1. The drive motor 12 on the shaft seat 10 drives the cutting shaft 14 to rotate, which in turn drives the circular cutting blade 13 to rotate. The speed and direction of rotation can be controlled by adjusting the speed and direction of the drive motor 12 according to actual needs. In practical use, the height of the guide seat 6 can be changed by rotating the adjusting nut seat 5 on the two studs 3, thereby controlling the compression degree of the compression spring 11 and changing the pressure applied by the compression spring 11 on the shaft seat 10. Ultimately, this changes the cutting pressure of the circular cutting blade 13 on the adhesive, ensuring smooth and stable cutting, smooth cutting edges, and high product quality.

[0019] The outer wall of the adjusting nut seat 5 is circular, and an annular limiting groove 17 is provided on the outer wall of the adjusting nut. The guide seat 6 has a through hole consistent with the outer wall of the adjusting nut seat 5, and an annular limiting protrusion 18 is provided on the inner wall of the through hole. The adjusting nut seat 5 is sleeved inside the through hole, and the annular limiting protrusion 18 fits within the annular limiting groove 17. The circular outer wall of the adjusting nut seat 5 and the through hole on the guide seat 6 allow them to be inserted together. Therefore, during the rotation of the adjusting nut seat 5, the guide seat 6 will not rotate with it, and there will be no interference. To prevent relative displacement between the guide seat 6 and the adjusting nut seat 5, an annular limiting groove 17 is provided on the outer wall of the adjusting nut seat 5, and a corresponding annular limiting protrusion 18 is provided in the through hole of the guide seat 6. The two work together to achieve a state where the guide seat 6 and the adjusting nut seat 5 can rotate relative to each other, but cannot experience axial displacement, ensuring a stable and reliable mating structure.

[0020] Several outwardly inclined support rods 7 are arranged circumferentially on the upper side of the adjusting nut seat 5. The tops of all the support rods 7 on the same adjusting nut seat 5 are fixedly connected by a connecting ring 8 to form an adjusting handle. To make the adjusting nut seat 5 easier to rotate and adjust, the inclined support rods 7 extend outward and are equipped with a connecting ring 8 at the top to form an adjusting handle. This type of adjusting handle forms a ring, which can be gripped from any position during adjustment, making operation more convenient. At the same time, the outwardly inclined support rods 7 increase the overall size of the adjusting handle, making the rotation of the adjusting nut seat 5 easier and less strenuous.

[0021] The cutting shaft 14 has five circular cutting blades 13. One of them is fixed in the middle of the cutting shaft 14 and is called the fixed cutting blade 131. Two circular cutting blades 13 are slidably sleeved on the cutting shaft 14 on both sides of the fixed cutting blade 131 and are called movable cutting blades 132. Two screws 15 are fixed on both sides of the fixed cutting blade 131. Two screws 15 are also provided on the movable cutting blades 132 near the fixed cutting blade 131. Two through holes are provided on each movable cutting blade 132. The through holes on the movable cutting blades 132 are inserted into the corresponding screws 15. Locking nuts 16 are provided on the screws 15 on both sides of the movable cutting blades 132.

[0022] Because the required dimensions of the cut and applied material vary during actual processing, the spacing between the circular cutting blades 13 needs to be adjusted. A central circular cutting blade 13 is fixed to the cutting shaft 14, forming a fixed cutting blade 131. Two circular cutting blades 13 are slidably connected to either side of the fixed blade, forming movable cutting blades 132. To ensure that the movable cutting blades 132 also remain relatively fixed to the cutting shaft 14 and that the spacing is adjustable, outwardly extending screws 15 are provided on both sides of the fixed cutting blade 131. Through holes are provided on the movable cutting blades 132 on the sides of the fixed cutting blade 131, through which the screws 15 pass and are positioned by locking nuts 16, thus adjusting the spacing between the movable cutting blades 132 and the fixed cutting blades 131. To secure the outermost movable cutting blade 132, an outwardly extending screw 15 is also provided on the outer sidewall of the middle movable cutting blade 132. A corresponding through hole is provided on the outermost movable cutting blade 132, through which the screw 15 passes and is fixed in place by a locking nut 16, thus determining the distance between the two movable cutting blades 132. Therefore, in actual use, the position of the movable cutting blade 132 on the corresponding screw 15 can be adjusted according to the actual situation, thereby adjusting the distance between the two adjacent circular cutting blades 13 and changing the cutting size of the patch. This method is highly applicable and easy to adjust. The adjusted movable cutting blade 132 is connected to the fixed cutting blade 131 as a whole and is fixed on the cutting shaft 14, forming an integrated structure. Moreover, because the patch thickness is small, the screw 15 does not affect the cutting of the patch by the circular cutting blade 13.

[0023] The screws 15 on the fixed cutting blade 131 and the movable cutting blade 132 are evenly distributed along the circumferential direction, with the screws 15 on the movable cutting blade 132 spaced 180° apart and the screws 15 on the fixed cutting blade 131 spaced 180° apart.

[0024] Two screws 15 are provided on each side of the fixed cutting blade 131, and the screws 15 are spaced 180° apart. Two screws 15 are also provided on the movable cutting blade 132, and the screws 15 are spaced 180° apart. Moreover, the screws 15 on the movable cutting blade 132 and the screws 15 on the fixed cutting blade 131 on the same side alternate, with uniform intervals and all at 90°. This combination results in good stability and uniform force distribution between the fixed cutting blade 131 and the movable cutting blade 132.
