Description

Technical Field

[0001] This utility model relates to the field of coating and cutting technology, specifically a coating and bonding cutting machine. Background Technology

[0002] Coating refers to the method of applying a paste polymer, molten polymer, or polymer melt onto paper, cloth, or plastic film to obtain composite materials. With the rapid development of modern industry, the coating process requires the use of cutting devices to cut the coating into segments, which can divide the finished coating into multiple coatings of the same size.

[0003] Chinese patent CN218778487U discloses an automatic cutting device for coating and winding. Its structure includes two base plates, each with two columns fixedly connected to its upper surface. Two fixing plates are also fixedly connected to the side walls of each column. A first motor is bolted to the outer wall of one of the fixing plates. Two shafts are rotatably connected to opposite sides of the two fixing plates via bearings. One end of one of the shafts is keyway connected to the output shaft of the first motor. When the first motor is activated, it rotates the output shaft, causing the shaft to rotate. This causes the shaft to drive a connecting rod to adjust its tilt, which in turn causes the connecting rod to adjust the tilt angle of the fixing rod and the rotating drum. This allows the rotating drum to adjust the tension of the coating, thereby pushing the coating higher and facilitating cutting by the cutter head during winding.

[0004] Based on the above, the inventors have discovered the following problems: the automatic cutting device for coating and winding described above uses a fixed-distance cutting method for the cutter disc assembly, which cannot adjust the cutting distance of the coating according to the user's needs, thus having certain limitations.

[0005] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a coating, bonding and cutting machine in order to achieve a more practical value. Utility Model Content

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0007] A coating and laminating cutting machine includes a cutting table, a laminating roller assembly, a pulling roller assembly, and an equidistant cutting mechanism. A gantry frame is mounted on the upper part of the cutting table. The equidistant cutting mechanism is fixed inside the gantry frame. A support protective cover is fixed to the upper end of the gantry frame. The equidistant cutting mechanism includes a support plate. Vertical limiting slide rails are provided on the left and right sides of the support plate, and horizontal limiting slide rails are provided on the upper and lower sides of the support plate.

The adjusting plate has multiple oblique sliding holes. The adjusting rod has an adjusting shaft on the other side, and the adjusting rod slides in the oblique sliding holes through the adjusting shaft. A cutting blade is slidably connected to the bottom end of the adjusting rod. A threaded seat is provided on the outer side of the adjusting plate, and a lead screw is rotatably connected to the threaded seat. A driven bevel gear is provided at the top end of the lead screw. A servo motor is provided at the top end of the gantry frame, and a driving bevel gear is driven to the output end of the servo motor. The driving bevel gear meshes with the driven bevel gear.

[0008] Furthermore, the bottom end of the adjusting rod is provided with a replacement buckle, and the top end of the cutting blade is provided with a replacement groove. The cutting blade is engaged with the replacement buckle at the bottom end of the adjusting rod through the replacement groove.

[0009] The beneficial effect of adopting the above-mentioned further solution is that the coating is pressed and bonded by the rolling of the bonding roller assembly. After the pressing is completed, the rolling of the pull roller assembly clamps the coating and rolls it straight out. At the same time, the cutting distance is adjusted by the equidistant cutting mechanism according to the user's needs. Under the pulling force of the pull roller assembly pulling the coating, the cutting blade of the equidistant cutting mechanism cuts the coating at equal intervals.

[0010] Furthermore, the upper and lower ends of the lead screw are rotatably connected to a support protective cover, which covers the servo motor, the driving bevel gear, the driven bevel gear, and the lead screw.

[0011] The beneficial effect of adopting the above-mentioned further solution is that by rotatably connecting the lead screw to the support protective cover, a support point is provided for the lead screw, while the support protective cover protects the servo motor, the driving bevel gear, the driven bevel gear and the lead screw from contact with the external space.

[0012] Furthermore, the bonding roller assembly includes a pair of first fixed seats, with an active bonding roller and a driven bonding roller rotatably connected between the pair of first fixed seats.

[0013] The beneficial effect of adopting the above-mentioned further solution is that the coating is pressed and bonded by the rotational cooperation of the active bonding roller and the driven bonding roller.

[0014] Furthermore, a first motor is provided on one side of one of the first fixed seats. The output end of the first motor passes through the first fixed seat and is connected to the active bonding roller. The other end of the active bonding roller passes through another first fixed seat and is fixedly connected to a first driving gear. One end of the driven bonding roller passes through the first fixed seat and is fixedly connected to a first driven gear. The first driving gear and the first driven gear mesh with each other.

[0015] The beneficial effect of adopting the above-mentioned further solution is that the first motor drives the active bonding roller to rotate, and at the same time drives the first drive gear of the active bonding roller, which in turn drives the first driven gear, thereby driving the driven bonding roller to rotate, thus realizing continuous pressure bonding of the coating.

[0016] Furthermore, the pull roller assembly includes a pair of second fixed seats, with an active pull roller and a driven pull roller rotatably connected between the pair of second fixed seats.

[0017] The beneficial effect of adopting the above-mentioned further solution is that the coated material is continuously stretched and taut by the rotational cooperation of the active pull roller and the driven pull roller.

[0018] Furthermore, a second motor is provided on one side of one of the second fixed seats. The output end of the second motor passes through the second fixed seat and is connected to the active pull roller. The other end of the active pull roller passes through another second fixed seat and is fixedly connected to a second active gear. One end of the driven pull roller passes through the second fixed seat and is fixedly connected to a second driven gear. The second active gear and the second driven gear mesh with each other.

[0019] The beneficial effect of adopting the above-mentioned further solution is that the second motor drives the active pulling roller to rotate, which in turn drives the second active gear of the active pulling roller. The second active gear drives the second driven gear, thereby driving the driven pulling roller to rotate, thus realizing the continuous straightening transmission of the coated material after lamination.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: This coating, bonding, and cutting machine uses a bonding roller assembly to press and bond the coating. After pressing, a pulling roller assembly clamps the coating and rolls it straight outward. While pulling, the equidistant cutting mechanism can be adjusted according to the user's needs. After adjusting the cutting distance, the coating is cut at equal intervals by multiple cutting blades of the equidistant cutting mechanism under the pulling force of the pulling roller assembly. This utility model can cut coatings with different spacing according to the user's needs and has high practical value. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-6This utility model provides a technical solution: a coating, bonding, and cutting machine, including a cutting table 100, a bonding roller assembly 101, a pulling roller assembly 102, and an equidistant cutting mechanism 104. A gantry frame 103 is provided at the upper end of the cutting table 100. The equidistant cutting mechanism 104 is fixed inside the gantry frame 103. A support protective cover 10301 is fixed at the upper end of the gantry frame 103. The equidistant cutting mechanism 104 includes a bearing plate 10415. Vertical limiting slide rails 10409 are provided on the left and right sides of the bearing plate 10415, and horizontal limiting slide rails 10407 are provided on the upper and lower sides of the bearing plate 10415. An adjusting plate 10405 is connected to the vertical limiting slide rails 10409. Vertical grooves 10410 are opened on the left and right sides of the adjusting plate 10405. 5. A vertical slide rail 10409 is slidably connected to a vertical limiting slide rail 10409 via a vertical slide groove 10410. An adjusting rod 10411 is connected to a horizontal limiting slide rail 10407. A pair of buckles 10412 are provided on one side of the adjusting rod 10411. The adjusting rod 10411 is slidably connected to the horizontal limiting slide rail 10407 via the buckles 10412. A plurality of oblique sliding holes 10406 ​​are provided on the adjusting plate 10405. An adjusting shaft 10413 is provided on the other side of the adjusting rod 10411. The adjusting rod 10411 slides within the oblique sliding holes 10406 ​​via the adjusting shaft 10413. A cutting blade 10414 is slidably connected to the bottom end of the adjusting rod 10411. A threaded seat 10408 is provided on the outer side of the adjusting plate 10405. A lead screw 1 is rotatably connected to the threaded seat 10408. 0403, the top of the lead screw 10403 is equipped with a driven bevel gear 10404, and the top of the gantry 103 is equipped with a servo motor 10401. The output end of the servo motor 10401 is connected to a driving bevel gear 10402. The driving bevel gear 10402 meshes with the driven bevel gear 10404. The coating is pressed and bonded by the rolling of the bonding roller assembly 101. After pressing, the coating is clamped by the rolling of the pull roller assembly 102 and conveyed straight outward. At the same time, the cutting distance is adjusted by the equidistant cutting mechanism 104 according to the user's needs. Under the pulling force of the pull roller assembly 102 pulling the coating, the cutting blade 10414 of the equidistant cutting mechanism 104 cuts the coating at equal intervals. The equidistant cutting mechanism 104 makes the coating equidistantly cut by the cutting blade 10414. In operation, the servo motor 10401 drives the active bevel gear 10402 to rotate, which in turn drives the lead screw 10403, which is fixed with the driven bevel gear 10404, to rotate. The lead screw 10403 rotates within the threaded seat 10408, causing the adjusting plate 10405 to move vertically upwards or downwards. Simultaneously, the adjusting plate 10405 moves, causing the adjusting shaft 10413, which is slidably connected within multiple oblique sliding holes 10406, to move. Because the oblique sliding holes 10406 ​​are designed with varying vertical spacing, they can be expanded or retracted, achieving an equidistant adjustment function. As the adjusting shaft 10413 expands or retracts, it also drives the adjusting rod 10411 and the cutting blade 10414 to move accordingly, thus achieving the function of adjusting the distance.After adjustment, the bonded coating is pulled by the pull roller assembly 102. Simultaneously, due to the pulling force, the coating is cut by multiple cutting blades 10414, allowing it to be cut to different cutting sizes.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figures 1-6 The bottom end of the adjusting rod 10411 is provided with a replacement buckle 105, and the top end of the cutting blade 10414 is provided with a replacement groove 10501. The cutting blade 10414 is engaged with the replacement buckle 105 at the bottom end of the adjusting rod 10411 through the replacement groove 10501. The upper and lower ends of the lead screw 10403 are rotatably connected to the support protective cover 10301. The support protective cover 10301 covers the servo motor 10401, the driving bevel gear 10402, the driven bevel gear 10404, and the lead screw 10403. The cutting blade 10414 is inserted through the replacement groove 10501 at the top end. The replacement buckle 105 at the bottom of the adjustment rod 10411 facilitates the disassembly and replacement of the cutting blade 10414 when it wears out after long-term use or when different cutting blades 10414 need to be replaced for different coating materials. The lead screw 10403 is rotatably connected to the support protective cover 10301 to provide a support point for the lead screw 10403. At the same time, the support protective cover 10301 protects the servo motor 10401, the active bevel gear 10402, the driven bevel gear 10404 and the lead screw 10403 from contacting the external space.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figures 1-6The bonding roller assembly 101 includes a pair of first fixed seats 10106, with an active bonding roller 10101 and a driven bonding roller 10102 rotatably connected between the pair of first fixed seats 10106. A first motor 10103 is provided on one side of one of the first fixed seats 10106. The output end of the first motor 10103 passes through the first fixed seat 10106 and is connected to the active bonding roller 10101. The other end of the active bonding roller 10101 passes through the other first fixed seat 10106 and is fixedly connected to a first drive gear 10105. One end of the driven bonding roller 10102 passes through the first fixed seat 10106. A first driven gear 10104 is fixedly connected to 106. A first driving gear 10105 meshes with the first driven gear 10104. The pull roller assembly 102 includes a pair of second fixed seats 10206. A driving pull roller 10201 and a driven pull roller 10202 are rotatably connected between the pair of second fixed seats 10206. A second motor 10203 is provided on one side of one of the second fixed seats 10206. The output end of the second motor 10203 passes through the second fixed seat 10206 and is drivenly connected to the driving pull roller 10201. The other end of the driving pull roller 10201 passes through the other second fixed seat 10206. A second driving gear 10205 is fixedly connected to a fixed base 10206. One end of a driven pull roller 10202 passes through the second fixed base 10206 and is fixedly connected to a second driven gear 10204. The second driving gear 10205 and the second driven gear 10204 mesh with each other. Through the rotational engagement of the driving bonding roller 10101 and the driven bonding roller 10102, the coating is pressed and bonded. The first motor 10103 drives the driving bonding roller 10101 to rotate, which in turn drives the first driving gear 10105 of the driving bonding roller 10101. The first driving gear 10105 then drives the first... Driven gear 10104 drives driven laminating roller 10102 to rotate, thereby achieving continuous pressing and laminating of the coating. Through the rotational cooperation of active pull roller 10201 and driven pull roller 10202, the laminated coating is continuously pulled and straightened. The second motor 10203 drives active pull roller 10201 to rotate, and at the same time drives the second active gear 10205 of active pull roller 10201. The second active gear 10205 drives the second driven gear 10204, thereby driving driven pull roller 10202 to rotate, thereby achieving continuous straightening transmission of the laminated coating.

[0034] Specifically, the working principle of this coating and bonding cutting machine is as follows: During use, the equidistant cutting mechanism 104 drives the active bevel gear 10402 to rotate via the servo motor 10401. The active bevel gear 10402 then drives the lead screw 10403, which is fixed with the driven bevel gear 10404, to rotate. The lead screw 10403 rotates within the threaded seat 10408, causing the adjusting plate 10405 to move vertically upward or downward. When the adjusting plate 10405 moves, it simultaneously drives the adjusting shaft 10413, which is slidably connected within multiple oblique sliding holes 10406, to move. Since the oblique sliding holes 10406 ​​are designed with different vertical spacing, the machine can expand or contract, which is the equidistant adjustment function. As the adjusting shaft 10413 expands or retracts, it drives the adjusting rod 10411 and the cutting blade 10414 to move accordingly, thereby achieving the function of adjusting the distance. After adjustment, the applied coating is pulled by the pull roller assembly 102. At the same time, due to the pulling force, the coating is cut by multiple cutting blades 10414 to cut the coating according to different cutting size requirements. The replacement slot 10501 at the top of the cutting blade 10414 is inserted into the replacement buckle 105 at the bottom of the adjusting rod 10411. This facilitates the replacement of the cutting blade 10414 when it wears down after long-term use, or when different cutting blades 10414 are needed for different coating materials. For disassembly and replacement, the lead screw 10403 is rotatably connected to the support protective cover 10301, providing a support point for the lead screw 10403. Simultaneously, the support protective cover 10301 protects the servo motor 10401, the driving bevel gear 10402, the driven bevel gear 10404, and the lead screw 10403 from contact with the external space. The active bonding roller 10101 and the driven bonding roller 10102 rotate to press and bond the coating. The first motor 10103 drives the active bonding roller 10101 to rotate, simultaneously driving the first driving gear 10105 of the active bonding roller 10101. The first driving gear 10105 then drives the first driven gear 10100. 4. This drives the driven bonding roller 10102 to rotate, thereby achieving continuous pressing and bonding of the coating. Through the rotational cooperation of the active pull roller 10201 and the driven pull roller 10202, the bonded coating is continuously pulled and straightened. The second motor 10203 drives the active pull roller 10201 to rotate, and at the same time drives the second drive gear 10205 of the active pull roller 10201. The second drive gear 10205 drives the second driven gear 10204, thereby driving the driven pull roller 10202 to rotate, thus achieving continuous straightening transmission of the bonded coating. This utility model can cut coatings with different spacing according to user needs and has high practical value.
