Description

Technical Field

[0001] This utility model relates to the technical field of roll material processing equipment, and in particular to a device for removing air bubbles using a winding pressure roller. Background Technology

[0002] In the production process of adhesive tapes such as PI, PET, and OPP, slitting machines cut wide master rolls into narrow strips of the required width. During the slitting and rewinding process, air is easily forced into the tape, forming air bubbles. These air bubbles not only affect the appearance of the tape roll but also the adhesion, flatness, and performance of the tape in subsequent use.

[0003] Existing winding devices typically use a large pressure roller to compact the entire wound roll. This method results in uneven pressure distribution and makes it difficult to precisely adjust the pressure for each individual roll. As the roll diameter gradually increases, fixed pressing angles or pressures may no longer be applicable, leading to over-compaction and material damage in some parts of the roll, while insufficient pressure prevents the effective removal of air bubbles in others. This results in poor adaptability and unsatisfactory performance. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0040] In one embodiment of this utility model, such as Figures 1-5 As shown, a rewinding pressure roller bubble removal device is provided, including a pressure roller slide assembly 10, a cylinder 203 mounting assembly 20, a pressure roller transmission assembly 30, an encoding detection assembly 40, and a rewinding assembly 50.

[0041] The pressure roller slide assembly 10 is mounted on the slide table devices on both sides of the wall panel. The pressure roller slide assembly 10 can be moved back and forth by driving the slide table screw to adjust the distance between the pressure roller slide assembly 10 and the winding assembly 50.

[0042] The cylinder 203 mounting assembly 20 and the pressure roller transmission assembly 30 are both mounted on the pressure roller slide assembly 10. The pressure roller transmission assembly 30 is mounted on the pressure roller slide assembly 10. The cylinder 203 mounting assembly 20 pushes the pressure roller transmission assembly 30 to swing, so that the pressure roller transmission assembly 30 presses the roll material.

[0043] The coding detection component 40 is disposed on the pressure roller slide assembly 10 and is connected to the pressure roller transmission assembly 30. The coding detection component 40 is used to detect the swing angle of the pressure roller transmission assembly 30. When the finished roll diameter increases and the angle exceeds the set value, the pressure roller transmission assembly 30 automatically retracts to adapt to the change in roll diameter.

[0044] The winding assembly 50 is used to wind up the roll material and is installed on the left side of the wall panel.

[0045] The air bubble removal device for the winding pressure roller provided by this utility model, through the cooperation of the pressure roller slide assembly 10, the cylinder 203 mounting assembly 20, the pressure roller transmission assembly 30, the coding detection assembly 40, and the winding assembly 50, can achieve independent pressure adjustment of a single roller to effectively remove air bubbles from the roll material according to the different air bubble distribution in different areas of the material, thereby improving the tightness and flatness of the roll material winding; and can also adjust the clamping force of each area in a targeted manner to effectively apply precise pressure to the roll material and effectively remove air bubbles from the roll material, thereby improving the tightness and flatness of the roll material winding, thus improving the quality of the product; and can also provide real-time feedback on changes in roll diameter to achieve automatic adjustment of the pressure roller position, ensuring the stability of pressure throughout the entire winding process.

[0046] In an embodiment of this invention, the pressure roller drive assembly 30 is connected to an independent pressure regulating valve (not shown in the figure). This valve independently drives the air pressure of the pressure roller drive assembly 30, allowing for independent adjustment of the pressure force applied to the roll material. During use, the operator can adjust the air pressure of one or more pressure roller drive assemblies 30 individually based on the material characteristics and the observed bubble distribution during winding. This achieves precise pressurization of localized areas, expelling bubbles from both sides of the roll material and improving the flatness of the winding process.

[0047] In an embodiment of this utility model, the pressure roller slide assembly 10 includes two parallel and oppositely arranged pressure roller slides 101. The pressure roller slides 101 are driven by a motor to rotate a slide screw, thereby realizing the forward and backward movement adjustment of the pressure roller slides 101. The basic support of this device is the two pressure roller slides 101. The pressure roller slides 101 are mounted on a wall panel through a slide device (not shown in the figure). The forward and backward movement adjustment of the pressure roller slides 101 is realized by driving the slide screw to rotate, so as to adapt to different work positions or initial alignment.

[0048] In this example, a first cover plate 102 is connected to one side of each of the two pressure roller slides 101, and a first small guide wheel 103 is connected between the two first cover plates 102. A second cover plate 105 is connected to the other side of each of the pressure roller slides 101, and a second small guide wheel 104 is connected between the two second cover plates 105. Specifically, the first small guide wheel 103 and the second small guide wheel 104 are parallel, and the first small guide wheel 103 and the second small guide wheel 104 are rotatably connected to the first cover plate 102 and the second cover plate 105, respectively. The first small guide wheel 103 and the second small guide wheel 104 are used to guide the roll material, and the roll material passes through the first small guide wheel 103 and the second small guide wheel 104 in sequence.

[0049] In an embodiment of this utility model, the cylinder 203 mounting assembly 20 includes a cylinder seat mounting rod 201 mounted on the pressure roller slide plate 101. A plurality of cylinder seats 202 are arranged on the cylinder seat mounting rod 201, and a cylinder 203 is mounted on each cylinder seat 202. The output shaft of each cylinder 203 is drively connected to a small pressure roller support shaft 204. The cylinder 203 drives the small pressure roller support shaft 204 to rotate, thereby causing the pressure roller transmission assembly 30 to swing. Specifically, the cylinder seats 202 are evenly spaced along the installation length direction of the cylinder seat mounting rod 201. Each cylinder seat 202 is detachably connected to the cylinder seat mounting rod 201. Each cylinder 203 is correspondingly embedded in the cylinder seat 202, and the output shaft of each cylinder 203 is coaxially connected to the small pressure roller support shaft 204, realizing the reciprocating linear drive of the small pressure roller support shaft 204.

[0050] In this embodiment of the invention, there are eighteen cylinders 203. The number of cylinder seats 202 and small pressure roller support shafts 204 corresponds one-to-one with the number of cylinders 203. Each cylinder 203 independently drives one pressure roller transmission assembly 30, allowing each pressure roller transmission assembly 30 to independently adjust its air pressure according to the distribution of air bubbles on the surface of the wound material. This achieves precise pressurization of a localized area, expelling air bubbles from both sides of the roll material. Of course, in other embodiments of the invention, the number of cylinders 203 is set according to the device specifications. This invention does not limit the number of cylinders 203 and allows for adjustment based on actual conditions.

[0051] In an embodiment of this utility model, small pressure roller support bushings 205 are provided on the left and right sides of the connector between the small pressure roller support shaft 204 and the cylinder 203. Specifically, there are thirty-six small pressure roller support bushings 205, and the small pressure roller support bushings 205 are made of wear-resistant material. Each group of two small pressure roller support bushings 205 are respectively sleeved on the outer sides of both ends of the small pressure roller support shaft 204 and respectively connected to the inner side of the connector of the cylinder 203, thereby effectively limiting the axial movement of the small pressure roller support shaft 204 and buffering the impact force when the cylinder 203 is driven.

[0052] In an embodiment of this utility model, the pressure roller transmission assembly 30 includes two third cover plates 301 disposed on the pressure roller slide plate 101. A near-winding guide roller shaft 302 is connected between the two third cover plates 301. A plurality of bearing top sleeves 303, a small pressure roller tail shaft 304, and a pressure roller swing arm 305 are connected to the near-winding guide roller shaft 302. The two sides of the pressure roller swing arm 305 are connected to the small pressure roller tail shaft 304, and a first bearing 3041 is installed inside the small pressure roller tail shaft 304. Specifically, there are eighteen bearing top sleeves 303, thirty-six small pressure roller tail shafts 304, and thirty-six pressure roller swing arms 305. The pressure swing arm is a double-arm structure, and its left and right ends are rotatably mounted on the wall panel through the small pressure roller tail shaft 304 and the first bearing 3041.

[0053] In an embodiment of this utility model, the pressure roller swing arm 305 is connected to a small pressure roller 306. A second bearing 308 and a small pressure roller shaft 307 are sequentially assembled inside the small pressure roller 306. Specifically, there are eighteen small pressure rollers 306, thirty-six second bearings 308, and eighteen small pressure roller shafts 307. The inner diameter of the second bearing 308 is adapted to the shaft of the small pressure roller 306, and its outer diameter is adapted to the end face of the small pressure roller 306. The small pressure roller 306 is connected to the pressure roller swing arm 305 via the internal second bearings 308 and the small pressure roller shaft 307. The small pressure roller support shaft 204 is drive-connected to the pressure roller swing arm 305. The cylinder 203 drives the small pressure roller support shaft 204 to swing the pressure roller swing arm 305, thereby controlling the small pressure roller 306 to press and release the roll material.

[0054] In an embodiment of this utility model, the encoding detection component 40 includes an encoder fixing plate 402 fixedly connected to the pressure roller slide plate 101. An encoder 401 is provided on the encoder fixing plate 402. The output shaft of the encoder 401 is connected to a first spur gear 404. The first spur gear 404 meshes with a second spur gear 403. The second spur gear 403 is connected to the near-winding guide roller shaft 302.

[0055] Specifically, the rotation of the near-winding guide wheel shaft 302 drives the second spur gear 403 to rotate. Since the second spur gear 403 meshes with the first spur gear 404, it drives the first spur gear 404 to rotate. The encoder 401 is connected to the second spur gear 403 through the first spur gear 404. The encoder 401 is used to detect the swing angle of the pressure roller swing arm 305. When the diameter of the finished product increases beyond the set value, the cylinder 203 is automatically controlled to drive the small pressure roller 306 to retract, ensuring stable pressure and avoiding material damage.

[0056] In an embodiment of this invention, the small pressure roller 306 is controlled by an independent cylinder 203, and an independent pressure regulating valve (not shown in the figure) is connected to the air passage of the cylinder 203. The pressure regulating valve is used to independently regulate the air pressure driving the pressure roller swing arm 305, so that the clamping force of the small pressure roller 306 on the roll material can be independently adjusted. During use, the operator can adjust the air pressure of one or more small pressure rollers 306 individually through the pressure regulating valve according to the material characteristics and the bubble distribution observed during winding, thereby achieving precise pressurization of local areas and expelling bubbles from both sides of the roll material.

[0057] In an embodiment of this utility model, the winding assembly 50 includes a winding differential shaft 501, a winding connecting shaft 502, and a winding shaft bearing seat 503. The winding differential shaft 501, the winding connecting shaft 502, and the winding shaft bearing seat 503 are connected sequentially, and the winding shaft bearing seat 503 is a side-arm type and installed on the left side of the wall panel, thereby ensuring the stable operation of the winding component. The material first passes through the first small guide wheel 103 and the second small guide wheel 104 for guidance, then passes between the small pressure rollers 306, and finally winds around the outer wall of the paper tube of the winding differential shaft 501, ensuring that the material is wrinkled and does not shift during the material passing through.

[0058] Working principle: The air bubble removal device of the winding pressure roller provided by this utility model guides the material through the first small guide roller 103 and the second small guide roller 104 during the slitting process, then through the small pressure roller 306, and finally wound around the outer wall of the paper tube of the winding slip shaft 501.

[0059] After the cylinder 203 is started, the output shaft of the cylinder 203 pushes the small pressure roller support shaft 204 to drive the pressure roller swing arm 305 to swing, so that the small pressure roller 306 presses the material on the outer wall of the paper tube. The air bubbles between the material layers or between the material and the paper tube are expelled by the pressure. At the same time, each cylinder 203 is connected to an independent pressure regulating valve on the air passage. The operator can adjust the air pressure of one or more pressure roller transmission components 30 individually according to the material characteristics and the air bubble distribution observed during winding, so as to achieve precise pressurization of local areas, expel air bubbles from both sides of the roll, and improve the flatness of winding.

[0060] During the winding process, the diameter of the finished product gradually increases, which will push the pressure swing arm to swing. The encoder 401 detects the change in the angle of the swing arm through the first spur gear 404 and the second spur gear 403. When the angle exceeds the set value, the cylinder 203 drives the small pressure roller 306 to automatically retract to adapt to the change in the roll diameter, always ensuring stable pressure and avoiding material damage.

[0061] The air bubble removal device for the winding pressure roller provided by this utility model, through the cooperation of the pressure roller slide assembly 10, the cylinder 203 mounting assembly 20, the pressure roller transmission assembly 30, the coding detection assembly 40, and the winding assembly 50, can achieve independent pressure adjustment of a single roller to effectively remove air bubbles from the roll material according to the different air bubble distribution in different areas of the material, thereby improving the tightness and flatness of the roll material winding; and can also adjust the clamping force of each area in a targeted manner to effectively apply precise pressure to the roll material and effectively remove air bubbles from the roll material, thereby improving the tightness and flatness of the roll material winding, thus improving the quality of the product; and can also provide real-time feedback on changes in roll diameter to achieve automatic adjustment of the pressure roller position, ensuring the stability of pressure throughout the entire winding process.

[0062] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
