Description

Technical Field

[0001] This invention belongs to the field of synthetic leather processing technology, and particularly relates to a base coating mechanism for synthetic leather processing with controllable material discharge. Background Technology

[0002] Synthetic leather is a plastic product that mimics the composition and structure of natural leather and can serve as a substitute. It is typically made with an impregnated non-woven fabric as the mesh layer and a microporous polyurethane layer as the grain layer. Both its front and back are very similar to leather, and it has broad application prospects. During the production of synthetic leather, a coating needs to be applied to the surface of the base fabric to adhere the coating. Current methods generally involve a continuously rotating coating roller that rolls and contacts the surface of the synthetic leather. The lower side of the coating roller contacts the coating in a coating tank, and then the roller rotates upwards to allow the coating to adhere to the synthetic leather. However, this type of coating roller... The contact area between the coating and the roller remains constant, meaning the area covered by the coating cannot change. However, different types of synthetic leather often have different widths. Since the coating roller cannot adjust its feeding area, when the feeding area of ​​the roller exceeds the width of the synthetic leather, a portion of the coating on both ends of the roller will be idle. This idle portion of the coating, due to continuous up-and-down rotation, will be contaminated by airborne dust, reducing its quality. Therefore, the existing structure needs to be upgraded to improve the adjustability of the coating surface on the roller. Summary of the Invention

[0003] To address the shortcomings of the prior art, the present invention provides a substrate coating mechanism for synthetic leather processing with a flexible and convenient adjustable coating surface on the coating roller.

[0004] To solve the above problems, the technical solution adopted by the present invention is as follows: A base coating mechanism for synthetic leather processing with controllable material discharge includes a positioning base, a roller groove, a storage box, a coating roller, an overflow plate, a bottom baffle plate, an internal baffle block, and a control mechanism. The positioning base has a roller groove at its upper center. A storage box is installed at the front and rear of the upper end of the positioning base. The coating roller is rotatably mounted on the roller groove. An overflow plate is installed below the roller groove. The overflow plate has a concave arc-shaped contact surface at its upper center and an overflow strip-shaped opening at its lower center. The overflow strip-shaped opening is located at the bottom center of the concave arc-shaped contact surface and is connected to it. The lower side of the coating roller abuts against the concave arc-shaped contact surface. The lower side of the overflow plate has a feeding cavity. A bottom baffle plate is installed on each side of the cavity. The upper side of the bottom baffle plate abuts against the lower two parts of the overflow strip opening to form a baffle structure. The upper inner side of the bottom baffle plate is connected to an internal baffle block. The internal baffle block is inserted into the overflow strip opening to form a baffle structure. The two internal baffle blocks constitute the overflow section. The control mechanism is installed on the positioning base. The control mechanism drives the two bottom baffle plates to move horizontally relative to each other. The bottom baffle plates drive the internal baffle blocks to move, so that the length of the overflow section between the two internal baffle blocks is adjusted. The paint inside the storage box is conveyed to the feeding cavity by gravity. The paint overflows upward through the overflow section to the lower side of the paint roller in the feeding cavity.

[0005] Furthermore, transmission housings are respectively provided on both sides of the roller groove; a drive cavity is provided inside the lower part of the positioning base; the outer end of the bottom baffle plate extends out from the feeding cavity and into the interior of the transmission housing; a linkage plate is provided inside the transmission housing, the upper inner side of the linkage plate is connected to the outer end of the bottom baffle plate, and a bottom transmission plate is provided on the lower inner side of the linkage plate; the bottom transmission plate extends into the drive cavity; the control mechanism is installed in the drive cavity, and the control mechanism drives the two bottom transmission plates to move synchronously relative to each other.

[0006] Furthermore, the control mechanism includes a control motor, a control block, and a rotating lead screw; drive slots are respectively provided on both sides of the lower end of the drive cavity; a rotating lead screw is rotatably installed in each drive slot, the threads of the two rotating lead screws are horizontally opposite to each other and are connected by a synchronous post; the control motor is installed on one side of the lower part of the drive cavity, and the inner side of the control motor is connected to the outer end of a rotating lead screw; a control block is installed on each end of the bottom transmission plate; a control block is slidably installed in each drive slot, and the control block is threadedly connected to the rotating lead screw.

[0007] Furthermore, the outer end of the bottom baffle plate is slidably connected to the side of the feed cavity.

[0008] Furthermore, the four sides of the coating roller are coated with a wear-resistant coating.

[0009] Furthermore, both the bottom baffle plate and the built-in baffle block are made of wear-resistant materials.

[0010] Furthermore, the front and rear sides of the feeding cavity are connected to the storage tank through feeding pipes.

[0011] Furthermore, feeding pipes are respectively provided on the upper outer side of the storage box.

[0012] The beneficial effects of this invention are as follows: 1. This invention changes the traditional direct feeding structure of the feeding trough. Instead, an overflow plate is installed below the roller trough, with an overflow strip opening. Paint overflows through this opening and contacts the paint roller. A bottom baffle plate abuts against the lower end of the overflow strip opening, forming a baffle structure. An internal baffle block is inserted into the overflow strip opening, also forming a baffle structure. The bottom baffle plate blocks the upward overflow of paint, while the internal baffle block prevents paint entering the overflow strip opening from flowing to the sides, thus achieving effective baffle control. A control mechanism drives the two bottom baffle plates to move horizontally relative to each other, causing the internal baffle block to move. This adjusts the length of the overflow section between the two internal baffle blocks. Paint inside the storage tank is then conveyed to the feeding cavity by gravity. Within the feeding cavity, the paint overflows upwards through the overflow section to the lower side of the paint roller, thus allowing for adjustable width of the paint contact area on the lower side of the paint roller.

[0013] 2. In order to achieve flexible and convenient drive control, the outer end of the bottom baffle plate extends from the feed cavity into the interior of the transmission box. The structure is extended into the drive cavity through the linkage plate and the bottom transmission plate. In this way, the motor drives the two control blocks to move relative to each other by rotating the lead screw, thereby enabling the two bottom transmission plates to move relative to each other, which in turn drives the linkage plate and the bottom baffle plate to move relative to each other. This achieves integrated adjustment of the two bottom baffle plates, making the drive flexible and convenient. Attached Figure Description

[0021] The invention will now be described in further detail with reference to the accompanying drawings.

[0022] like Figures 1 to 7 As shown, a base coating mechanism for synthetic leather processing with controllable material discharge includes a positioning base 1, a roller groove 2, a storage box 3, a coating roller 4, an overflow plate 5, a bottom baffle plate 6, an internal baffle block 7, and a control mechanism 8. The positioning base 1 has a roller groove 2 at its upper center. A storage box 3 is installed at the front and rear of the upper end of the positioning base 1. The coating roller 4 is rotatably mounted on the roller groove 2. An overflow plate 5 is installed below the roller groove 2. The overflow plate 5 has a concave arc-shaped contact surface 51 at its upper center and an overflow strip opening 52 at its lower center. The overflow strip opening 52 is located at the bottom center of the concave arc-shaped contact surface 51 and is connected to it. The lower side of the coating roller 4 abuts against the concave arc-shaped contact surface 51. The lower side of the overflow plate 5 has an inlet cavity 11. A bottom baffle plate 6 is installed on each side of the material cavity 11. The upper side of the bottom baffle plate 6 abuts against the lower two parts of the overflow strip opening 52 to form a baffle structure. The upper inner side of the bottom baffle plate 6 is connected to the built-in baffle block 7. The built-in baffle block 7 is inserted into the overflow strip opening 52 to form a baffle structure. The two built-in baffle blocks 7 constitute the overflow section 53. The control mechanism 8 is installed on the positioning base 1. The control mechanism 8 drives the two bottom baffle plates 6 to move horizontally relative to each other. The bottom baffle plates 6 drive the built-in baffle blocks 7 to move, so that the length of the overflow section 53 between the two built-in baffle blocks 7 is adjusted. The paint inside the storage box 3 is conveyed to the feeding cavity 11 by gravity. The paint overflows upward through the overflow section 53 in the feeding cavity 11 to the lower side of the paint roller 4.

[0023] like Figures 1 to 7As shown, to facilitate the transmission control of the two bottom baffles 6, transmission housings 9 are provided on both sides of the roller groove 2; a drive cavity 12 is provided inside the lower part of the positioning base 1; the outer end of the bottom baffle 6 extends out from the feed cavity 11 and into the interior of the transmission housing 9; a linkage plate 91 is provided inside the transmission housing 9, the inner side of the upper end of the linkage plate 91 is connected to the outer end of the bottom baffle 6, and a bottom transmission plate 92 is provided on the inner side of the lower end of the linkage plate 91; the bottom transmission plate 92 extends into the drive cavity 12; the control mechanism 8 is installed in the drive cavity 12, and the control mechanism 8 drives the two bottom transmission plates 92 to move synchronously relative to each other.

[0024] like Figures 1 to 7 As shown, to facilitate relative driving control of the two bottom baffles 6, the control mechanism 8 further includes a control motor 81, a control block 82, and a rotating lead screw 83; the lower end of the drive cavity 12 is provided with drive slots 121 on both sides; a rotating lead screw 83 is rotatably installed in each drive slot 121, the threads of the two rotating lead screws 83 are horizontally distributed relative to each other and connected by a synchronous column 831; the control motor 81 is installed below one side of the drive cavity 12, and the inner side of the control motor 81 is connected to the outer end of a rotating lead screw 83; a control block 82 is installed at each end of the bottom transmission plate 92; a control block 82 is slidably installed in each drive slot 121, and the control block 82 is threadedly connected to the rotating lead screw 83.

[0025] like Figures 1 to 7 As shown, to ensure sealing, the outer end of the bottom baffle plate 6 is further sealed and slidably connected to the side of the feed cavity 11. To improve wear resistance, the four sides of the paint roller 4 are coated with a wear-resistant coating. Furthermore, both the bottom baffle plate 6 and the built-in baffle block 7 are made of wear-resistant material. To facilitate feeding, the front and rear sides of the feed cavity 11 are connected to the storage tank 3 via feed pipes 111. Furthermore, feeding pipes 31 are respectively provided on the upper outer side of the storage tank 3.

[0026] This invention changes the traditional direct feeding structure of the feeding trough. Instead, an overflow plate 5 is installed below the roller trough 2. The overflow plate 5 has an overflow strip opening 52, allowing the paint to overflow through this opening and contact the paint roller 4. A bottom baffle plate 6 abuts against the lower ends of the overflow strip opening 52, forming a baffle structure. An internal baffle block 7 is inserted into the overflow strip opening 52, also forming a baffle structure. Thus, the bottom baffle plate 6 blocks the upward overflow of paint, while the internal baffle block 7 prevents further overflow. The paint in the overflow strip opening 52 flows to both sides, thus achieving effective material blocking. The control mechanism 8 drives the two bottom baffles 6 to move horizontally relative to each other. The bottom baffles 6 drive the built-in baffle blocks 7 to move, so that the length of the overflow section 53 between the two built-in baffle blocks 7 is adjusted. In this way, the paint inside the storage box 3 is conveyed to the feeding cavity 11 by gravity. The paint overflows upward through the overflow section 53 in the feeding cavity 11 to the lower side of the paint roller 4, thereby making the width of the paint contact area on the lower side of the paint roller 4 adjustable.

[0027] To achieve flexible and convenient drive control, the outer end of the bottom baffle plate 6 extends from the feed cavity 11 into the interior of the transmission box 9. The structure is extended into the drive cavity 12 via the linkage plate 91 and the bottom transmission plate 92. In this way, the control motor 81 drives the two control blocks 82 to move relative to each other by rotating the lead screw 83. This causes the two bottom transmission plates 92 to move relative to each other, which in turn drives the linkage plate 91 and the bottom baffle plate 6 to move relative to each other. This achieves integrated adjustment of the two bottom baffle plates 6, making the drive flexible and convenient.
