Description

Technical Field

[0001] This invention belongs to the field of synthetic leather coating technology, and particularly relates to a coating structure for synthetic leather processing with separation and closure adjustment. Background Technology

[0002] In the synthetic leather industry, the first step is to coat a surface layer and a foam layer onto release paper to form a film. Then, an adhesive layer is applied to the surface of the film, and a base fabric is bonded to the adhesive-coated film. Subsequent processes yield the finished synthetic leather. Currently, the adhesive coating structure for synthetic leather generally involves applying adhesive using a rolling adhesive roller. The bottom surface of the conveyor belt contacts the upper side of the roller, thus achieving adhesive application. This structure typically requires a matching adhesive tank. A large amount of adhesive is poured into the tank, and the adhesive roller is then rotated and mounted within the tank. The lower side of the glue roller contacts the glue in the glue tank. As the glue roller rotates continuously, it continuously rolls and applies glue. However, with this structure, a large amount of glue is stored in the glue tank, making it susceptible to contamination. Furthermore, the process of recycling the glue after the operation is completed is cumbersome, increasing the risk of glue contamination. In addition, different operation requirements necessitate matching glue rollers of different diameters, and the existing structure cannot be flexibly adjusted. Therefore, it is necessary to upgrade and modify the existing structure to avoid the accumulation of a large amount of glue and improve the adaptability of the structure to glue rollers of different diameters. Summary of the Invention

[0003] To address the shortcomings of the prior art, the present invention provides a coating structure for synthetic leather processing that eliminates the need for large amounts of adhesive to be exposed and accumulated, and allows for the adjustment of separation and closure for coating rollers of different diameters.

[0004] To solve the above problems, the technical solution adopted by the present invention is as follows: A synthetic leather coating structure for separation and closure adjustment includes a base, a positioning box, a glue storage cylinder, a glue application roller, a movable glue application plate, a floating docking cover, and a control mechanism. The positioning box is mounted on the upper side of the base. A glue storage cylinder is mounted on each of the upper sides of the positioning box. A glue application roller is mounted on the upper interior of the positioning box. A movable glue application plate is mounted on each of the lower sides of the glue application roller, with the two movable glue application plates facing each other. The upper side of each movable glue application plate has a glue-storing arc surface, which communicates with the glue storage cylinder. The positioning box contains a floating docking cover that floats vertically in the lower center. A control mechanism is mounted on the positioning box and drives two movable glue-applying plates to move relative to each other. When the two movable glue-applying plates move closer together and abut, the two glue-storing arc surfaces form a small feeding trough. When the two movable glue-applying plates move apart relative to each other, the floating docking cover moves upwards between the two movable glue-applying plates, and the two movable glue-applying plates clamp the floating docking cover, forming a large feeding trough between the two glue-storing arc surfaces and the upper side of the floating docking cover.

[0005] Furthermore, a power cylinder is provided in the lower center of the interior of the positioning box; the upper end of the power cylinder is connected to the lower center of the floating docking cover via a telescopic shaft.

[0006] Furthermore, it also includes a connecting component; the connecting component includes a glue discharge tube, a telescopic conduit, a bottom positioning tube, and an external through-tube; a glue discharge tube is respectively connected to the movable glue-applying plate, and the upper end of the glue discharge tube extends to the glue storage arc surface; an external through-tube is respectively installed below the glue storage cylinder, and the external through-tube is inserted into the interior of the positioning box; a bottom positioning tube is installed on the upper side of the end of the external through-tube; the upper end of the bottom positioning tube and the lower end of the glue discharge tube are connected through a telescopic conduit.

[0007] Furthermore, the upper side of the bottom positioning tube is connected to the side of the positioning box body via a fixed bracket.

[0008] Furthermore, the external connecting pipe is equipped with a flow control valve to prevent the adhesive from overflowing from the small and large feeding troughs.

[0009] Furthermore, the control mechanism includes an opening and closing motor, a rotating shaft, a power rod, and a drive block; drive rails are respectively opened on the front and rear sides of the positioning box; drive blocks are respectively installed on the front and rear sides of the movable upper plate; the drive blocks are slidably engaged with the drive rails; an opening and closing motor is installed on the front and rear sides of one side of the positioning box; the inner side of the opening and closing motor is connected to the power rod through the rotating shaft; the power rod rotatably passes through the drive rail, and the power rod is threadedly connected to the two drive blocks, and the rotation of the power rod controls the relative sliding of the two drive blocks.

[0010] Furthermore, the front and rear sides of the movable adhesive plate are respectively connected to the drive block via support rods.

[0011] Furthermore, the two sides of the power rod are respectively provided with threaded annular surfaces with oppositely distributed threads, and a drive block is sleeved on each threaded annular surface.

[0012] Furthermore, the bottom of the glue storage cylinder is located above the glue storage arc surface.

[0013] The beneficial effects of this invention are as follows: 1. This invention, through structural upgrades and modifications, changes the traditional glue coating structure. By distributing a movable glue-applying plate on each of the two sides below the glue-applying roller, during normal operation, the two movable glue-applying plates are joined together, forming a small feeding trough. A glue storage cylinder then supplies glue to this small feeding trough, ensuring continuous contact between the lower side of the glue-applying roller and the glue in the small feeding trough, achieving a balance between glue supply and application, thus eliminating glue accumulation. When applying glue to a large-diameter glue-applying roller, the control mechanism drives the two movable glue-applying plates to move relative to each other. A floating docking cover then moves upwards between the two movable glue-applying plates, and the control mechanism again drives the two movable glue-applying plates to clamp the floating docking cover. This forms a large feeding trough with the two glue-storing arc surfaces and the upper side of the floating docking cover, enabling rolling glue application to large-diameter glue-applying rollers, making it flexible and convenient to use.

[0014] 2. The bottom of the glue storage cylinder in this invention is located above the glue storage arc surface. Thus, through gravity operation and the principle of communicating vessels, the glue liquid inside the glue storage cylinder will be automatically transported into the glue storage arc surface. By setting a flow control valve on the external pipe, the glue liquid in the small and large feeding troughs will not overflow by adjusting the flow control valve, so as to achieve a balance between the glue liquid delivery volume and the glue application volume of the glue roller.

The control mechanism 7 drives two movable glue-applying plates 5 to move relative to each other. When the two movable glue-applying plates 5 move closer to each other and abut, the two glue-storing arc surfaces form a small feeding groove 52; When the two movable glue-applying plates 5 move apart relative to each other, the floating docking cover 6 moves upward between the two movable glue-applying plates 5. The two movable glue-applying plates 5 clamp the floating docking cover 6, so that the two glue-storing arc surfaces and the upper side of the floating docking cover 6 form a large feeding groove 53.

[0022] like Figures 1 to 5 As shown, in order to facilitate the up-and-down driving of the floating docking cover 6, a power cylinder 8 is further provided in the lower middle of the interior of the positioning box 2; the upper end of the power cylinder 8 is connected to the lower middle of the floating docking cover 6 through a telescopic shaft 81.

[0023] like Figures 1 to 5 As shown, to facilitate the delivery of adhesive from the glue storage cylinder 3 to the movable glue application plate 5, a connecting component 9 is further included. This connecting component includes a glue discharge pipe 91, a telescopic conduit 92, a bottom positioning pipe 93, and an external through-pipe 94. A glue discharge pipe 91 is connected to each of the movable glue application plates 5, with the upper end of the discharge pipe 91 extending to the glue storage arc surface 51. An external through-pipe 94 is installed below each of the glue storage cylinders 3, and the external through-pipe 94 passes through the interior of the positioning box 2. A bottom positioning pipe 93 is installed on the upper side of the end of the external through-pipe 94. The upper end of the bottom positioning pipe 93 and the lower end of the glue discharge pipe 91 are connected via the telescopic conduit 92. Furthermore, the upper side of the bottom positioning pipe 93 is connected to the side of the positioning box 2 via a fixed bracket 931. To facilitate control of the glue dispensing volume, a flow control valve 941 is provided on the external through-pipe 94, preventing adhesive overflow from the small and large feeding troughs 52 and 53.

[0024] like Figures 1 to 5 As shown, to facilitate the horizontal relative opening and closing movement of the two movable adhesive plates 5 by the control mechanism 7, the control mechanism 7 further includes an opening and closing motor 71, a rotating shaft 72, a power rod 73, and a drive block 74; drive rails 21 are respectively opened on the front and rear sides of the positioning box 2; drive blocks 74 are respectively installed on the front and rear sides of the movable adhesive plates 5; the drive blocks 74 are slidably engaged with the drive rails 21; an opening and closing motor 71 is installed on the front and rear sides of one side of the positioning box 2; the inner side of the opening and closing motor 71 is connected to the power rod 73 through the rotating shaft 72; the power rod 73 rotatably passes through the drive rails 21, and the power rod 73 is threadedly connected to the two drive blocks 74, and the power rod 73 rotates and controls the relative sliding of the two drive blocks 74. Further, the front and rear sides of the movable adhesive plates 5 are respectively connected to the drive blocks 74 through support rods 54. Further, the two sides of the power rod 73 are respectively provided with threaded annular surfaces with oppositely distributed threads, and a drive block 74 is respectively sleeved on the threaded annular surface.

[0025] like Figures 1 to 5 As shown, in order to automatically dispense glue by gravity, the bottom of the glue storage cylinder 3 is located above the glue storage arc surface 51.

[0026] This invention, through structural upgrades, changes the traditional glue application structure. A movable glue application plate 5 is distributed on each of the two sides below the glue application roller 4. During normal operation, the two movable glue application plates 5 are joined together, forming a small feeding trough 52 with their glue-storing arc surfaces 51. The glue storage cylinder 3 then supplies glue to the small feeding trough 52, ensuring continuous contact between the lower side of the glue application roller 4 and the glue in the small feeding trough 52, achieving a balance between glue supply and application, thus eliminating glue accumulation. When applying glue to a large-diameter glue application roller 4, the control mechanism 7 drives the two movable glue application plates 5 to move relative to each other. Then, a floating docking cover 6 moves upward between the two movable glue application plates 5, and the control mechanism 7 drives the two movable glue application plates 5 to clamp the floating docking cover 6. This forms a large feeding trough 53 with the two glue-storing arc surfaces 51 and the upper side of the floating docking cover 6, enabling rolling glue application to the large-diameter glue application roller 4, making it flexible and convenient to use.

[0027] The bottom of the glue storage cylinder 3 in this invention is located above the glue storage arc surface 51. Thus, through gravity operation and the principle of communicating vessels, the glue liquid inside the glue storage cylinder 3 is automatically transported into the glue storage arc surface 51. By setting a flow control valve 941 on the external through pipe 94, the glue liquid in the small feeding trough 52 and the large feeding trough 53 will not overflow by adjusting the flow control valve 941, so as to achieve a balance between the glue liquid delivery amount and the glue application amount of the glue application roller 4.
