Description

Technical Field

[0001] This utility model relates to the field of coating machine technology, and more specifically, to a double-point coating machine for lining production. Background Technology

[0002] A double-dot coating machine is a high-end piece of equipment specifically designed for the textile industry. It is primarily used to produce high-grade bonded interlinings (such as garment linings and non-woven interlinings). It achieves bonding by forming a precise "double-dot" coating structure (sizing dots + powder dots) on the base fabric. For example, patent application CN202222412331.9 describes a double-dot coating equipment for interlinings, comprising a base plate, two conveyor tables, a suction device, and a residual powder recovery device. The two conveyor tables are fixed to the upper part of the base plate by multiple support rods. A first guide roller and a second guide roller are rotatably connected between the two conveyor tables. A conveyor belt is drivenly connected to the first and second guide rollers. The surface of the conveyor belt has mesh holes. The suction device is located on the conveyor belt. The residual powder recovery device includes a powder suction box and a first recovery box. The powder suction box has multiple through holes on both sides. The two ends of the conveyor belt are movably connected to the multiple through holes respectively. The powder suction box and the first recovery box are connected through a conveying assembly. This utility model can not only prevent glue powder from flying during the powder coating process, but also recover excess powder on the lining cloth, thereby reducing costs and environmental pollution. When coating lining cloths of different widths, the material sprayed from the conveyor cylinder has the same length. When coating lining cloths that are not wide enough, the sprayed material will not coat the surface of the lining cloth, resulting in a large waste of material. Utility Model Content

[0003] The main purpose of this utility model is to provide a double-dot coating machine for lining production, which can effectively solve the problem in the background art where, when coating linings of different widths, the material sprayed from the feed cylinder has the same length, but when coating linings that are not wide enough, the sprayed material will not coat the surface of the lining, resulting in a lot of waste of material.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a double-dot coating machine for lining production, comprising a processing table, two mounting side plates slidably mounted through the upper surface of the processing table, a feeding cylinder rotatably mounted between the two mounting side plates, a nickel mesh cylinder sleeved in the middle of the feeding cylinder, an adjustment component for blocking the feeding cylinder provided on the upper surface of the processing table, a first gear fixedly mounted in the middle of the feeding cylinder, a second servo motor fixedly mounted on the surface of one of the mounting side plates, a second gear mounted on the output end of the second servo motor, and the second gear meshing with the first gear.

[0005] Preferably, a number of guide rollers are installed at equal intervals between the two mounting side plates.

[0006] Preferably, a base is installed on the lower surface of the processing table, a connecting plate is fixedly installed between the lower ends of the two mounting side plates, a hydraulic cylinder is fixedly installed on the upper surface of the base, and the output end of the hydraulic cylinder is located on the lower surface of the connecting plate.

[0007] Preferably, a first servo motor is fixedly mounted on the side of one of the mounting side plates, a rotating shaft is mounted on the output end of the first servo motor, and a scraper is mounted on the circumference of the rotating shaft.

[0008] Preferably, the adjustment component includes a guide groove and a retaining ring. The guide groove is formed on the upper surface of the processing table, and the retaining ring is sleeved between the feed cylinder and the nickel mesh cylinder.

[0009] Preferably, a guide block is slidably installed inside the guide groove, and a screw is installed on the inner wall of the guide groove by a screw sleeve, with the top end of the screw rotatably disposed on the surface of the guide block.

[0010] Preferably, a groove is provided on the circumferential surface of one end of the retaining ring, a slider is slidably installed inside the groove, a support rod is fixedly installed on the upper surface of the guide block, and the top end of the support rod is disposed on the circumferential surface of the slider.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] (1) By rotating the screw, the screw moves forward in conjunction with the screw sleeve, which drives the guide block to slide inside the guide groove. At the same time, it drives the retaining ring to move forward. Since the retaining ring is sleeved between the feed cylinder and the nickel mesh cylinder, the retaining ring will block the feed cylinder, preventing the raw material from being sprayed out from the feed cylinder blocked by the retaining ring. The length of the raw material sprayed from the feed cylinder is adjusted to be suitable for the width of the lining to coat the lining, thus avoiding waste of the coating.

[0013] (2) The hydraulic cylinder output end is extended and retracted, which drives the mounting side plate to move, thereby adjusting the height of the mounting side plate on the processing table, adjusting the distance between the nickel mesh cylinder and the table to a suitable distance from the lining cloth, and coating the lining cloth of different specifications.

[0019] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0020] like Figure 1 , 4 As shown, a double-dot coating machine for lining production includes a processing table 1. Two mounting side plates 5 are slidably mounted through the upper surface of the processing table 1. A feed cylinder 9 is rotatably mounted between the two mounting side plates 5. A nickel mesh cylinder 10 is sleeved in the middle of the feed cylinder 9. An adjustment component 4 is provided on the upper surface of the processing table 1 to block the feed cylinder 9. A first gear 13 is fixedly mounted in the middle of the feed cylinder 9. A second servo motor 14 is fixedly mounted on the surface of one of the mounting side plates 5. A second gear 15 is mounted on the output end of the second servo motor 14. The second gear 15 is meshed with the first gear 13.

[0021] like Figure 1 As shown, several guide rollers 11 are installed at equal intervals between the two mounting side plates 5, which can make the lining cloth more taut during the coating process and ensure the coating quality.

[0022] like Figure 1As shown, a base 2 is installed on the lower surface of the processing table 1, and a connecting plate 12 is fixedly installed between the lower ends of the two mounting side plates 5. A hydraulic cylinder 3 is fixedly installed on the upper surface of the base 2. The output end of the hydraulic cylinder 3 is located on the lower surface of the connecting plate 12. By extending and retracting the output end of the hydraulic cylinder 3, the mounting side plates 5 can be moved to adjust the height of the mounting side plates 5 on the processing table 1, and adjust the distance between the nickel mesh cylinder 10 and the table to a suitable distance from the lining cloth, so as to coat the lining cloth of different thicknesses.

[0023] like Figure 2 , 3 As shown, a first servo motor 6 is fixedly installed on the side of one of the mounting side plates 5. A rotating shaft 7 is installed at the output end of the first servo motor 6. A scraper 8 is installed on the circumference of the rotating shaft 7. By driving the rotating shaft 7 to rotate through the first servo motor 6, the tilt angle of the scraper 8 can be adjusted to adjust the pressure of the scraper against the nickel mesh cylinder 10, and to coat the linings of different specifications.

[0024] like Figure 2 , 3 As shown, the adjustment assembly 4 includes a guide groove 401 and a retaining ring 405. The guide groove 401 is formed on the upper surface of the processing table 1. The retaining ring 405 is sleeved between the feed cylinder 9 and the nickel mesh cylinder 10. A guide block 402 is slidably installed inside the guide groove 401. A screw 404 is installed on the inner wall of the guide groove 401 through a screw sleeve 403. The top end of the screw 404 is rotatably set on the surface of the guide block 402. A sliding groove 406 is formed on the circumferential surface of one end of the retaining ring 405. A slider 407 is slidably installed inside the sliding groove 406. A support rod 408 is fixedly installed on the upper surface of the guide block 402. The top of the 8 is located on the circumference of the slider 407. When the operator rotates the screw 404, the screw 404 moves forward in conjunction with the screw sleeve 403. At the same time, the guide block 402 slides inside the guide groove 401, which in turn drives the retaining ring 405 to move forward. Since the retaining ring 405 is sleeved between the feed cylinder 9 and the nickel mesh cylinder 10, the retaining ring 405 will block the feed cylinder 9, preventing the raw material from being sprayed out from the position of the feed cylinder 9 blocked by the retaining ring 405. The length of the raw material sprayed from the feed cylinder 9 is adjusted to be suitable for the width of the lining cloth to coat the lining cloth, avoiding waste of coating.

[0025] The working principle of a double-dot coating machine for lining production:

[0026] In use, when this device is needed to coat the lining, firstly, the output end of the hydraulic cylinder 3 is extended or retracted, which drives the mounting side plate 5 to move and adjust its height on the processing table 1. This adjusts the distance between the nickel mesh cylinder 10 and the table to a suitable distance from the lining. Then, the coating material is fed into the conveying cylinder 9. The conveying cylinder 9 has several spray holes on its circumference, and the material is sprayed into the space between the conveying cylinder 9 and the nickel mesh cylinder 10. The lining is then placed between the nickel mesh cylinder 10 and the upper surface of the processing table 1. At this point, the output end of the second servo motor 14 drives the second gear 15 to rotate, which in turn drives the first gear 13 to rotate, thus driving the conveying cylinder 9 to rotate, causing the nickel mesh cylinder 10 to rotate. This, combined with the lining, pulls the material. As the nickel mesh cylinder 10 rotates... When the scraper 8 squeezes the slurry in the nickel mesh cylinder 10 to form regular slurry dots, it is evenly coated on the surface of the lining, making it easier for the workers to carry out the next processing work. When it is necessary to coat the lining with different widths, the workers can rotate the screw 404, which moves forward in conjunction with the screw sleeve 403. At the same time, it can drive the guide block 402 to slide inside the guide groove 401, and drive the retaining ring 405 to move forward. Since the retaining ring 405 is sleeved between the feed cylinder 9 and the nickel mesh cylinder 10, the retaining ring 405 will block the feed cylinder 9, preventing the raw material from being sprayed out from the position of the feed cylinder 9 blocked by the retaining ring 405. The length of the raw material sprayed from the feed cylinder 9 is adjusted to be suitable for the width of the lining to coat the lining and avoid waste of coating.

[0027] The above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
