Description

Technical Field

[0001] The invention relates to the technical field of glue coating die heads, in particular to a high-viscosity glue coating die head. Background Art

[0002] The gap-type glue coating die is a key coating equipment, which is widely used to evenly coat liquid materials such as glue and coating on the surface of various substrates. Its structure mainly consists of a shell, a glue inlet, a gap, a glue outlet and an adjustment device. The gap is the core part of the die, which is a narrow gap formed by two parallel plates. The width and shape of the gap can be adjusted according to the coating requirements to achieve different coating effects. The working principle is based on fluid mechanics and pressure difference. When the liquid enters the gap through the glue inlet, due to the small width of the gap, the liquid generates shear force when flowing here, making the flow more uniform. At the same time, the liquid pressure in the die also makes the coating material flow out of the glue outlet at a certain speed to ensure the uniformity of coating. As disclosed in the authorization announcement number CN217595038U, a high-viscosity glue coating die head comprises a lower die head and an upper die head fixedly connected, a slit glue outlet is provided at the front end of the joint surface of the lower die head and the upper die head, the lower die head is provided with a front transverse groove connected to the glue outlet and a plurality of glue inlets, a glue flow channel with a tree-type topological structure is provided between each glue inlet and the front transverse groove, and a plurality of independent glue flow channels with a tree-type topological structure are provided, and the glue flow channels are injected into the front transverse groove at the end thereof with a diffusion groove opening toward the front transverse groove, thereby reducing the pressure of the glue when it moves. However, during the use of the above technical solution, the glue inside the die head needs to be collected at the front transverse groove and uniformly sprayed out through the slit glue outlet. At this time, the glue If the surface is a whole surface, then in order to make the glue surface adapt to the width of the coating material, it is necessary to install a gasket between the lower die head and the upper die head, and use the gasket to divide the glue surface so that the glue surface width is adapted to the width of the coating material. Due to the increase of gaskets, the slit glue outlet also becomes wider. When the gap becomes wider, the outflow of glue will increase, resulting in an increase in coating thickness. In addition, the pressure balance originally designed inside the die head is broken by the gasket, forming a new pressure gradient field. Especially when the coating width is large, the glue may be too thick in some areas and insufficient in other areas. This unevenness will directly affect the quality of the coating material and cause problems in subsequent processes (such as drying and curing). Summary of the invention

[0003] The purpose of the present invention is to provide a high-viscosity glue coating die head. The liquid inlet base uses a multi-point diversion type glue inlet structure to feed the high-viscosity glue liquid into the lower die head and the upper die head, and allows the glue liquid to enter the slope gap type glue outlet channel between the lower die head and the upper die head. At this time, the gasket between the lower die head and the upper die head divides the glue liquid surface into several channels. Finally, the lower screw-type glue thickness adjuster and the upper screw-type glue thickness adjuster are operated to control the width of the glue outlet seam, so that the thickness of the glue liquid can be controlled after entering the glue outlet seam from the slope gap type glue outlet channel, so as to solve the problems raised in the above-mentioned background technology.

DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] Embodiment 1, by Figures 1 to 4The present invention comprises a liquid inlet platform 1, a lower die head 2 fixed at the top of the liquid inlet platform 1, an upper die head 3 bolted and installed at the top of the lower die head 2, and a gasket 10 installed between the joint surfaces of the lower die head 2 and the upper die head 3. A multi-point diversion type glue inlet structure 5 for supplying glue to the lower die head 2 is installed on one side of the top of the liquid inlet platform 1, a glue inlet joint 4 is installed on the outer wall of one side of the liquid inlet platform 1, a slope gap type glue outlet channel 203 is arranged at the opening position of the side of the lower die head 2 and the upper die head 3 away from the multi-point diversion type glue inlet structure 5, an upper screw-type glue thickness adjuster 8 and a lower screw-type glue thickness adjuster 9 are respectively arranged on the outer walls of the side of the lower die head 2 and the upper die head 3 away from the multi-point diversion type glue inlet structure 5, and a glue outlet seam 11 for interconnecting with the slope gap type glue outlet channel 203 is arranged between the upper screw-type glue thickness adjuster 8 and the lower screw-type glue thickness adjuster 9.

[0019] Embodiment 2, based on embodiment 1, Figure 5 , Figure 6 , Figure 7 and Figure 8 It is shown that the multi-point split-flow glue feeding structure 5 includes a plurality of right-angle joints 501 installed at equal intervals in a linear array at the top of the multi-point split-flow glue feeding structure 5 and a plurality of L-shaped flow channels 502 arranged inside the lower die head 2, one end of the right-angle joint 501 away from the liquid inlet base 1 is connected to one end of the L-shaped flow channel 502, and the upper surface of the lower die head 2 is provided with a plurality of tree-type topological flow channels 201 having the same number as the L-shaped flow channels 502 and a linear connecting channel 202 arranged on the upper surface of the lower die head 2 on one side of the tree-type topological flow channels 201 away from the right-angle joint 501; The glue inlet joint 4 delivers the glue supplied by the external glue delivery device into the liquid inlet base 1, and then the glue in the liquid inlet base 1 is sequentially diverted to the right-angle joint 501, and enters the glue flow channel of the lower die head 2 through the L-shaped flow channel 502. The multi-point diverting glue inlet structure 5 evenly distributes the glue to the lower die head 2, ensuring that each flow channel area can obtain the same glue supply to avoid local uneven coating; The right-angle joint 501 delivers the glue in the liquid inlet base 1 to the tree-shaped topological flow channel 201 through the L-shaped flow channel 502. The straight connecting channel 202 is used to connect a number of tree-shaped topological flow channels 201 in the same straight line direction and deliver the glue to the slope gap type glue outlet channel 203. The slope gap type glue outlet channel 203 gradually tilts upward from one side close to the straight connecting channel 202 to the other side. The slope gap type glue outlet channel 203 has an inclination angle of 3°-8° with the upper surface of the die head 2 as the reference plane. When the glue enters the tree-type topological flow channel 201 of the lower die head 2 through the L-shaped flow channel 502, the tree-type topological flow channel 201 optimizes the flow path of the glue and reduces the flow resistance through a reasonable branch design. At this time, the glue in each tree-type topological flow channel 201 will eventually flow into the straight connecting channel 202, and then enter the slope gap type glue outlet channel 203 and spray out from the glue outlet gap 11. The straight connecting channel 202 is used to improve the efficiency of glue delivery and ensure that the glue quickly reaches the coating area; The gasket 10 is made of a nickel-chromium-molybdenum alloy. A plurality of ribs 1002 are integrally formed on one side of the gasket 10 close to the tree-shaped topological flow channel 201. A convex notch 1001 is formed between two adjacent ribs 1002. The convex notch 1001 and the edge position of the tree-shaped topological flow channel 201 coincide with each other. The top and bottom ends of the ribs 1002 are integrally formed with a slope block 1003. The ribs 1002 form a blocking portion in the slope gap-type rubber outlet 203 through the slope block 1003. Each convex notch 1001 corresponds to a tree-shaped topological flow channel 201, and the slope blocks 1003 at the top and bottom ends of the rib 1002 are used to form a barrier in the slope gap glue outlet channel 203, so that the glue is separated at the slope block 1003, thereby dividing the glue in the slope gap glue outlet channel 203 into glue strips of equal width for subsequent coating.

[0020] Embodiment 3, based on embodiment 2, Fig. 9 , Fig.10 , Fig.11 and Fig.12 The upper screw-type glue thickness adjuster 8 and the lower screw-type glue thickness adjuster 9 have the same structural composition. The upper screw-type glue thickness adjuster 8 includes a support 801 installed on the outer wall of the left and right ends of the upper die head 3, an internally threaded cylinder 802 installed on the top of the support 801, a slide column 804 slidably installed inside the internally threaded cylinder 802, and an externally threaded handle 803 threadedly installed on the top of the internally threaded cylinder 802. The bottom end of the externally threaded handle 803 is rotatably connected to the top of the slide column 804. Next, a seam adjusting plate 805 is fixed on the outer wall of the sliding column 804 away from the upper die head 3, and a folding edge 806 is integrally formed on the outer wall of the side of the seam adjusting plate 805 close to the slope surface gap type glue outlet 203. The glue outlet 11 is arranged below the folding edge 806, and the folding edge 806 is connected with one of the side edges of the slope surface gap type glue outlet 203, so that the glue in the slope surface gap type glue outlet 203 enters the glue outlet 11 between the two folding edges 806, and the glue is sprayed out; An opening for the seam adjusting plate 805 to rise and fall and slide is provided on one side of the outer wall of the inner threaded cylinder 802. A semicircular sleeve for fixing the outer threaded handle 803 is bolted and installed on one side of the surface of the inner threaded cylinder 802. When adjusting the width of the glue outlet seam 11, the staff rotates the two outer threaded handles 803 at the same time, and the outer threaded handles 803 drive the slide column 804 to move in the vertical direction of the inner threaded cylinder 802, and then the slide column 804 drives the seam adjusting plate 805 to move up or down. At this time, the seam adjusting plate 805 in the upper screw-type glue thickness adjuster 8 and the lower screw-type glue thickness adjuster 9 can be adjusted. The width of the glue outlet seam 11 can be adjusted by controlling the distance between the two seam adjusting plates 805, thereby allowing the operator to make fine adjustments, and the coating thickness of the glue liquid can be accurately controlled to meet the needs of different products. The top of the upper die head 3 is provided with a plurality of bolts 6 which enter into the lower die head 2. Hinges 7 are provided on both sides of the back of the lower die head 2 and the upper die head 3. When the gasket 10 is assembled, the gasket 10 is located at the joint surface of the lower die head 2 and the upper die head 3, and the lower die head 2, the upper die head 3 and the gasket 10 are bolted and fixed by the bolts 6. When the staff is inspecting and maintaining the lower die head 2 and the upper die head 3, the staff will unscrew the bolts 6 from the lower die head 2 and the upper die head 3 one by one until the connection restriction of the lower die head 2 and the upper die head 3 is released. Then the staff will flip up the upper die head 3, so that the upper die head 3 is deflected with the hinge 7, and then the lower die head 2 and the upper die head 3 can be opened. At this time, the staff will remove the gasket 10 and clean and maintain the flow channels in the lower die head 2 and the upper die head 3.

[0021] Before starting the coating operation in the embodiment of the present application, it is first necessary to conduct a comprehensive inspection of all relevant components to ensure that the glue inlet joint 4, the liquid inlet base 1, the lower die head 2 and the upper die head 3 are intact, and special attention should be paid to the sealing to prevent leakage of the glue. In addition, the flexibility and accuracy of the upper screw-type glue thickness adjuster 8 and the lower screw-type glue thickness adjuster 9 are checked to ensure that the two are working normally. Then, according to the coating requirements, the required high-viscosity glue is prepared. The viscosity and formula of the glue should meet the production requirements to ensure that it can flow smoothly during the coating process. In order to avoid precipitation or stratification of the glue during the transportation process, the glue needs to be fully stirred before use; after confirming that all connections are correct, the external glue delivery device is started, and the glue enters the liquid inlet base 1 from the glue inlet joint 4 through the external glue delivery device, and is evenly distributed to the lower die head 2 and the upper die head 3 through the multi-point diversion glue inlet structure 5. At this time, the glue enters the slope gap glue outlet 203 of the lower die head 2 and the upper die head 3, and then the glue begins to flow from the tree topology After the glue outlet 11 flows out from the slope gap glue outlet 201, the operator should carefully observe the coating effect during the process, check whether the uniformity and thickness of the glue meet the requirements, and whether there are bubbles or other defects; according to the coating requirements of the product, use the upper screw-type glue thickness adjuster 8 and the lower screw-type glue thickness adjuster 9 to accurately adjust the width of the glue outlet 11 to ensure that the glue can flow out from the slope gap glue outlet 203 and the glue outlet 11 with the required thickness; during the process of the glue flowing out, the gasket 10 divides the glue surface into a number of glue strips of equal width according to the width of the coated substrate; after the coating is completed, the glue will solidify on the substrate. According to the characteristics of the glue, the operator needs to control the curing time and environmental conditions according to the requirements of the product to ensure that the glue can achieve the best bonding effect. After the coating operation is completed, the die head should be cleaned in time, especially the glue inlet joint 4, the liquid inlet base 1, the lower die head 2 and the upper die head 3 parts, which need to be thoroughly cleaned to prevent the glue residue from causing damage to the equipment or problems during the next use.
