Description

Technical Field

[0001] The present invention relates to the technical field of coating machines, and particularly to a coating machine facilitating the replacement of a material roll. Background Art

[0002] Coating machines are mainly used in the surface coating process production of films, papers, etc. This machine coats a roll of base material with a specific functional glue, coating, ink, etc., dries it and then winds it up. It uses a special multi-functional coating head to achieve various forms of surface coating. The unwinding and rewinding of the coating machine are both equipped with a full-speed automatic film splicing mechanism, and the PLC program tension closed-loop automatic control. When producing films, the unwinding mechanism of the coating machine is required. The existing unwinding mechanism needs manual replacement of the material roll after unwinding, and it is easy to make the lateral position of the material roll unstable during replacement, which affects the coating.

Applying this technical solution, when replacing the material roll, the pushing cylinder pushes the air shaft support plate to slide backward along the linear guide rail, and the air shaft is in a single-sided fixed state. After replacement, the pushing cylinder is started again to push the air shaft support plate forward, and the U-shaped card slot at the front end of the air shaft support plate catches the rotating sleeve, which is convenient for replacing the material roll, reduces the labor cost, and effectively improves the work efficiency; although this device can realize the replacement of the material roll, it still requires personnel to operate to pick up and place the material cylinder during use, which greatly wastes time, and it cannot fix the lateral position of the material roll after replacement, which is easy to affect the subsequent coating. Therefore, a device that can quickly replace the unwinding cylinder and process the empty cylinder after unwinding is needed. Summary of the Invention

During operation, the fabric to be coated passes through the roller IV 108 and the roller III 107, and then is coated by the coating assembly 4, and then passes through the gap formed by the roller II 106 and the roller I 105, and then is fixed on the winding drum 104. By starting the motor I 110, the winding drum 104 is driven to rotate to wind the coated fabric.

[0031] The clamping assembly 2 includes a fixed seat 204 fixedly mounted on a rotating shaft 504. Slide shafts 205 are slidably mounted at both ends of the fixed seat 204. Deflection support rings 206 are fixedly mounted on the two slide shafts 205 respectively. A plurality of support bars (the number is set according to requirements) are provided on the deflection support rings 206. The support bars are rotatably mounted with the deflection support rings 206 and are in contact connection with the slide shafts 205. A sliding pressing strip I 202 and a sliding pressing strip II 203 are slidably mounted on the fixed seat 204. A motor II 201 is fixedly mounted on the fixed seat 204. A gear is fixedly mounted on the output shaft of the motor II 201. The gear meshes with the rack parts of the sliding pressing strip I 202 and the sliding pressing strip II 203. During operation, the motor II 201 rotates to drive the sliding pressing strip I 202 and the sliding pressing strip II 203 to move towards both ends of the fixed seat 204, thereby pressing the slide shafts 205 at both ends of the fixed seat 204, so that the upper ends of the support bars on the deflection support ring 206 contact the fixed seat 204 and rotate, so that the lower ends of the support bars move away from the slide shafts 205, thereby supporting the empty sleeve 601 to facilitate the transfer of the empty sleeve 601.

[0032] The temporary storage component 3 includes a temporary storage box 301 fixedly installed on the support plate II 103. A cylinder I 302 is fixedly installed on the temporary storage box 301. The thin shaft end of the cylinder I 302 is hinged with a baffle I 303, and the baffle I 303 is slidably installed with the temporary storage box 301.

During operation, the empty sleeve 601 wound with the fabric is sequentially ejected by the spring assembly at the bottom of the temporary storage box 301. The baffle I 303 is pushed by the cylinder I 302 to deflect, so that the empty sleeve 601 wound with the fabric falls onto the bearing plate II 305 and the bearing plate I 304. At this time, the empty sleeve 601 wound with the fabric is heavier, so that the limiting strip I 307 on the bearing plate I 304 is clamped into the limiting plate I 309, so that the bearing plate II 305 and the bearing plate I 304 are on the same horizontal plane, and then wait for the clamping component 2 to transfer the empty sleeve 601 wound with the fabric. After the transfer is completed, the empty sleeve 601 is placed on the bearing plate II 305 and the bearing plate I 304. At this time, the limiting plate I 309 is moved by the cylinder, so that the limiting plate I 309 releases the limiting strip I 307, so that the bearing plate I 304 is ejected, so that a stepped surface is formed between the bearing plate I 304 and the bearing plate II 305, so that the empty sleeve 601 slides from the opening on the support plate II 103 to the outlet groove 111, thus completing the removal of the empty sleeve 601 and the loading of the empty sleeve 601 wound with the fabric.

A rack and a limiting strip are fixedly installed on the central sliding shaft 502. The rack on the central sliding shaft 502 meshes with the gear on the output shaft of the motor III 501. The limiting strip on the central sliding shaft 502 is used to prevent the central sliding shaft 502 from rotating. The roll-changing assembly 5 further includes a fixed sleeve 505 fixedly installed on the support plate II 103. A top block I 506 and a top block II 507 are fixedly installed on the fixed sleeve 505. A rotating shaft 504 is rotatably installed on the central sliding shaft 502. A spring III 509, a spring IV 511, and a spring V 515 are fixedly installed on the rotating shaft 504. A pushing ring I 508, a pushing ring II 510, and a limiting column 514 are slidably installed on the rotating shaft 504. One end of the spring III 509 is fixedly installed with the pushing ring I 508, and the other end is fixedly installed with the rotating shaft 504. One end of the spring IV 511 is fixedly installed with the pushing ring II 510, and the other end is fixedly installed with the rotating shaft 504. One end of the spring V 515 is fixedly installed with the limiting column 514, and the other end is fixedly installed with the rotating shaft 504. A limiting card strip II 512 and a pressing card strip I 513 are fixedly installed on the pushing ring I 508. The limiting card strip II 512 and the pressing card strip I 513 are installed in the built-in cavity of the rotating shaft 504 through a connecting slider. The pressing card strip I 513 is in contact connection with the limiting column 514. Two pressing card strips II 516 are fixedly installed on the pushing ring II 510. Two deflecting plates 517 are rotatably installed on the built-in cavity of the rotating shaft 504. The two deflecting plates 517 are respectively hinged to the two pressing card strips II 516. The limiting card strip II 512 forms a snap connection with the deflecting plate 517. A slide rail groove is provided on the fixed sleeve 505. The slide rail groove includes a first curved section, a first straight section, a second curved section, and a second straight section;During operation, by starting the motor III 501, the central sliding shaft 502 is driven to move, and then the rotating shaft 504 slides in the fixed sleeve 505. During the sliding, it is restricted by the limiting column 514, so that the rotating shaft 504 rotates along with the chute. When in the first curve section of the chute, the rotating shaft 504 rotates along with the chute, and then drives the fixed seat 204 to rotate, so that the two sliding shafts 205 on the fixed seat 204 respectively align with the empty sleeve 601 (located on the fixed shaft cylinder 604) and the empty sleeve 601 wrapped with cloth (located on the carrier plate I 304 and the carrier plate II 305). After alignment, the two empty sleeves 601 are supported and clamped by the clamping assembly 2. Then it enters the first straight section of the chute. At this time, the rotating shaft 504 stops rotating and moves along with the central sliding shaft 502, and then drives the clamping assembly 2 to move linearly, so that the two empty sleeves 601 completely protrude. After complete protrusion, it enters the second curve stage of the chute. At this time, under the restriction of the limiting column 514, the rotating shaft 504 rotates 180° along with the chute, so that the clamping assembly 2 drives the two empty sleeves 601 to exchange positions, making the empty sleeve 601 align with the temporary storage assembly 3 and the empty sleeve 601 wrapped with cloth align with the fixed shaft cylinder 604. Then it enters the second straight stage of the chute. As the central sliding shaft 502 moves, it drives the rotating shaft 504 to move, so that the top block II 507 on the fixed sleeve 505 touches and pushes the pushing ring I 508 to move, and then the pressing strip I 513 presses the limiting column 514 to move downward. At the same time, the limiting strip II 512 moves and is stuck into the buckle formed by the two deflecting pieces 517. After the limiting column 514 moves downward, the chute of the fixed sleeve 505 does not restrict the rotation of the rotating shaft 504 at this time. Then the motor III 501 reverses, driving the central sliding shaft 502 to move back, and then driving the rotating shaft 504 to move back, so that the empty sleeve 601 enters the temporary storage assembly 3, and the empty sleeve 601 wrapped with cloth enters the fixed shaft cylinder 604. When returning to the vicinity of the beginning of the first straight section, the top block I 506 on the fixed sleeve 505 touches and pushes the pushing ring II 510 to move, and then drives the pressing strip II 516 to push the deflecting piece 517, so that the deflecting piece 517 releases the restriction on the limiting strip II 512, and the pushing ring I 508 resets under the action of the spring III 509, so that the pressing strip I 513 releases the restriction on the limiting column 514, and then the limiting column 514 protrudes under the action of the spring V 515, so that the limiting column 514 is stuck into the chute of the fixed sleeve 505 again. Then the clamping assembly 2 releases the restriction on the two empty sleeves 601, and restricts the empty sleeve 601 wrapped with cloth through the stabilizing assembly 6. Then it enters the first curve stage of the chute. The limiting column 514 drives the rotating shaft 504 to deflect under the action of the chute, so that the two sliding shafts 205 on the fixed seat 204 make way, thus facilitating the processing of the empty sleeve 601 (such as cloth traction and reel addition).;

[0035] The stabilizing component 6 includes an empty sleeve 601 and a material 603, and further includes a connecting seat 602 fixedly installed on the support plate II 103. A fixed shaft cylinder 604 is fixedly installed on the connecting seat 602. The fixed shaft cylinder 604 is shorter than the empty sleeve 601. Two moving clamping bars 605 are slidably installed on the connecting seat 602. Spring VI 606 is fixedly installed on each of the two moving clamping bars 605. One end of the spring VI 606 is fixedly installed on the moving clamping bar 605, and the other end of the spring VI 606 is fixedly installed on the connecting seat 602. A runner 607 is rotatably installed on the connecting seat 602. Two raised blocks are provided on the runner 607, and the two raised blocks are respectively slidably installed with the two moving clamping bars 605. A motor IV 608 is also fixedly installed on the support plate II 103. The output shaft of the motor IV 608 is fixedly installed with the runner 607. A limiting groove for restricting the displacement of the material roll is provided on the empty sleeve 601, and the limiting groove cooperates with the moving clamping bar 605. During operation, the empty sleeve 601 wrapped with the fabric is placed on the fixed shaft cylinder 604 through the roll changing component 5 and the clamping component 2. The moving clamping bar 605 is clamped into the limiting groove of the empty sleeve 601, thereby preventing the empty sleeve 601 from undergoing lateral displacement during coating. When it is necessary to remove the empty sleeve 601, the motor IV 608 is started to rotate, thereby driving the runner 607 to deflect, so that the two moving clamping bars 605 move towards the middle along with the convex blocks on the runner 607, so that the moving clamping bar 605 releases the restriction on the empty sleeve 601, so that the empty sleeve 601 can be taken out to complete the replacement work.

[0036] The working principle of a coating machine for facilitating roll replacement disclosed by the present invention is as follows: During operation, the empty sleeve 601 that needs to be replaced and the empty sleeve 601 wrapped with the fabric are replaced through the roll changing component 5 and the clamping component 2. After the rapid replacement is completed, the empty sleeve 601 is removed through the temporary storage component 3 to complete the roll replacement. At the same time, the coating of the fabric is completed through the guide wheel component 1 and the coating component 4. During coating, the stabilizing component 6 prevents the empty sleeve 601 from undergoing lateral displacement and affecting the coating.
