Description

Technical Field

[0001] This utility model belongs to the field of stripe coating production technology, specifically relating to a multi-layer composite stripe coating die head. Background Technology

[0002] A stripe coating die is a precision coating component used to achieve a stripe coating effect. It is a core component of coating equipment, and its main function is to uniformly coat liquid materials (such as paints, inks, and adhesives) onto a substrate in a stripe pattern. It is widely used in industries such as packaging printing, electronic materials, building materials, and textile printing and dyeing.

[0003] Traditional coating dies have many limitations in achieving multi-layer lamination and specific stripe patterns. Most traditional coating dies can only perform single-layer coating, making it difficult to meet the needs of products requiring multi-layer structures. Some designs use a one-piece structure, which, while enabling multi-layer coating to some extent, offers extremely poor flexibility. When different production requirements need to be met, such as changing the number of coating layers, the combination of materials in each layer, or the coating thickness, one-piece dies cannot be quickly adjusted or have components replaced, making it inconvenient to adjust production specifications.

[0004] Therefore, a multi-layer composite stripe coating die head is proposed to solve the problems of being able to perform only single-layer coating, being unable to make quick adjustments, and being inconvenient to adjust production specifications. Utility Model Content

[0005] The purpose of this invention is to address the problems mentioned in the background art by referring to an existing multi-layer composite striped coating die.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] A multi-layer composite striped coating die head includes a main die head, a guide die tightly fitted to the inclined surface of the main die head, the main die head producing a substrate, and an outlet die tightly fitted to the inclined surface of the guide die away from the main die head for reinforcing the composite stripes on both sides of the substrate. The main die head, the guide die, and the outlet die are all provided with fixing plates for fixing. Side plates are nested on the outside of the fixing plates, and the side surfaces of the side plates are provided with several auxiliary plates for positioning.

[0008] The feeding mold includes a feeding mold and a discharging mold. The feeding mold has a first coating groove and a second coating groove respectively opened on the two inclined sides near the main mold head and the discharge mold. The feeding mold has a feeding groove on the lower end face. Several striped plates are fixed on the inner surface of the feeding groove. The feeding mold has a first inlet and a second inlet on the upper end face. The first inlet is connected to the first coating groove, and the second inlet is connected to the second coating groove. The feeding mold and the discharging mold have the same structure.

[0009] The present invention further describes that the main die head includes an upper die head and a lower die head, which are connected by a hinge. The upper die head and the lower die head have a main feed port at the end away from the inclined surface. The upper die head and the lower die head each have a core groove on their opposite surfaces, and the core groove is used to extrude the substrate.

[0010] The present invention further explains that the discharge mold includes an upper discharge mold and a lower discharge mold, and discharge grooves are provided on the opposite surfaces of the upper discharge mold and the lower discharge mold. The discharge grooves are used to extrude the substrate and composite stripes, and the lower end face of the upper discharge mold and the upper end face of the lower discharge mold are in close contact.

[0011] This utility model further illustrates that the fixing plate is provided with a plurality of screws, which are used to fix the fixing plate, the main mold head, the guide mold and the discharge mold.

[0012] The present invention further describes that the auxiliary plate is provided with a plurality of screws, which are used to fix the auxiliary plate, the main mold head, the guide mold and the discharge mold. The auxiliary plates located at the upper and lower ends of the side plate are used to position the side plate, the guide mold and the discharge mold, and the auxiliary plate located at the side end of the side plate away from the discharge mold is used to position the side plate and the main mold head.

[0013] This utility model further illustrates that the lower end face of the upper mold head and the upper end face of the lower mold head are in close contact, and the lower end face of the feeding mold and the upper end face of the unloading mold are in close contact.

[0014] This utility model further explains that the No. 1 feed port, the No. 2 feed port and the main feed port are respectively connected to the external material supply pipe.

[0015] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0016] Multi-layer lamination: The main die head, as the key starting component of the entire production process, precisely produces the substrate, laying a solid foundation for subsequent lamination processes. The guide die produces composite stripes, with key indicators such as stripe shape and size precisely controlled. The discharge die plays a crucial reinforcing role, tightly bonding and reinforcing the substrate produced by the main die head and the composite stripes produced by the guide die. Through a scientifically designed structure, a strong lamination is ensured, ultimately achieving multi-layer composite stripe coating production, effectively improving product quality and performance.

[0017] The modular structure facilitates adjustment of production specifications: the guide die can be replaced according to different coating requirements. When changing the width, spacing, or amount of coating stripes, simply replace the upper and lower dies with the corresponding specifications for precise coating, meeting the needs of multiple product specifications and improving coating effectiveness. When producing products of different thicknesses or shapes, replacing the upper and lower extrusion dies with the appropriate specifications allows for accurate extrusion through the discharge channels, ensuring that the product shape and dimensions meet standards and improving the pass rate. Production specifications can be changed without opening the entire die head. Attached Figure Description

[0024] The following detailed, non-limiting description of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0025] like Figures 1 to 4 As shown, the multi-layer composite stripe coating die head of this embodiment includes a main die head 1, a guide die 2 tightly attached to the inclined surface of the main die head 1, the main die head 1 produces the substrate, and an discharge die 3 tightly attached to the inclined surface of the guide die 2 away from the main die head 1, which is used to reinforce the composite stripes on both sides of the substrate. The side end faces of the main die head 1, the guide die 2 and the discharge die 3 are all provided with fixing plates 4 for fixing. Side plates 5 are nested on the outside of the fixing plates 4, and the side surface of the side plates 5 is provided with several auxiliary plates 6 for positioning.

[0026] The system comprises a split structure consisting of a main die head 1, a guide die 2, and an ejector die 3. This structure allows for flexible replacement and adjustment to meet different production needs, accommodating the production of various product specifications. The main die head 1, guide die 2, and ejector die 3 are secured by a fixing plate 4 and side plates 5. Screws are installed on the fixing plate 4, threaded through it and connecting to the main die head 1, guide die 2, and ejector die 3 respectively, ensuring a tight connection between all components. Auxiliary plates 6 are also connected to the components via screws. Auxiliary plates 6 located at the upper and lower ends of the side plates 5 are used to position the side plates 5, guide die 2, and ejector die 3. Auxiliary plates 6 located on the side of the side plates 5 furthest from the ejector die 3 are used to position the side plates 5 and the main die head 1, ensuring accurate relative positioning of each component during operation and improving coating precision and stability.

[0027] The feeding mold 2 includes a feeding mold 201 and a discharging mold 202. The feeding mold 201 has a first coating groove 203 and a second coating groove 204 respectively on the two inclined sides near the main mold head 1 and the discharge mold 3. The feeding mold 201 has a feeding groove 205 on its lower end face. Several striped plates 206 are fixed on the inner surface of the feeding groove 205. The feeding mold 201 has a first feed port 207 and a second feed port 208 on its upper end face. The first feed port 207 is connected to the first coating groove 203, and the second feed port 208 is connected to the second coating groove 204. The feeding mold 201 and the discharging mold 202 have the same structure.

[0028] Raw materials of different compositions enter through feed inlet 207 and feed inlet 208 respectively, and flow through coating tank 203 and coating tank 204 to guide trough 205. In guide trough 205, the raw materials are blocked and guided by stripe plate 206 to form composite stripes with specific shape and size. These composite stripes will be combined with the substrate produced by main die head 1.

[0029] The main die head 1 includes an upper die head 101 and a lower die head 102, which are connected by a hinge 103. The upper die head 101 and the lower die head 102 have a main feed port 104 at the end away from the inclined surface. The upper die head 101 and the lower die head 102 have a core groove 105 on their opposite surfaces, which is used to extrude the substrate.

[0030] The main die head 1 includes an upper die head 101 and a lower die head 102, connected by a hinge 103 for easy opening and closing, and convenient maintenance and replacement of internal components. A main feed inlet 104 is provided at the end of the upper die head 101 and the lower die head 102 away from the inclined surface, connecting to an external material supply pipe to receive raw materials for producing the substrate. Core grooves 105 are provided on the opposite surfaces of the upper die head 101 and the lower die head 102. After the raw material enters through the main feed inlet 104, it is compressed within the core groove 105, thereby producing a substrate that meets the requirements, providing the basic material for subsequent lamination processes.

[0031] The discharge mold 3 includes an upper discharge mold 301 and a lower discharge mold 302. The upper discharge mold 301 and the lower discharge mold 302 are provided with discharge grooves 303 on their opposite surfaces. The discharge grooves 303 are used to extrude the substrate and composite stripes. The lower end face of the upper discharge mold 301 and the upper end face of the lower discharge mold 302 are in close contact.

[0032] The fixing plate 4 is provided with several screws, which are used to fix the fixing plate 4, the main mold head 1, the guide mold 2 and the discharge mold 3. The screws on the fixing plate 4 pass through the fixing plate 4 and are threadedly connected to the main mold head 1, the guide mold 2 and the discharge mold 3 respectively.

[0033] When the substrate produced by the main die head 1 and the composite stripes produced by the guide die 2 enter the discharge die 3 area, the upper discharge die 301 and the lower discharge die 302 move relative to each other, and the discharge groove 303 extrudes the substrate and the composite stripes. Through this extrusion action, the substrate and the composite stripes are tightly bonded together, achieving multi-layer composite, ensuring that the two are firmly bonded together, and improving the quality and performance of the product.

[0034] The auxiliary plate 6 is provided with several screws, which are used to fix the auxiliary plate 6, the main mold head 1, the guide mold 2 and the discharge mold 3. The auxiliary plates 6 located at the upper and lower ends of the side plate 5 are used to position the side plate 5, the guide mold 2 and the discharge mold 3. The auxiliary plates 6 located at the side end of the side plate 5 away from the discharge mold 3 are used to position the side plate 5 and the main mold head 1. The screws on the auxiliary plate 6 pass through the auxiliary plate 6 and are threadedly connected to the main mold head 1, the guide mold 2 and the discharge mold 3 respectively.

[0035] The lower end face of the upper mold head 101 and the upper end face of the lower mold head 102 are in close contact, and the lower end face of the feeding mold 201 and the upper end face of the unloading mold 202 are in close contact.

[0036] The No. 1 feed inlet 207, the No. 2 feed inlet 208 and the main feed inlet 104 are respectively connected to the external feed pipeline.

[0037] Operating Principle: The main die head 1 is connected to the upper die head 101 and the lower die head 102 via a hinge 103. Before use, gently pull open the upper die head 101 and check whether the inside of the die core groove 105 is clean and free of foreign objects. After confirming that everything is in order, close the upper die head 101 so that the lower end face of the upper die head 101 and the upper end face of the lower die head 102 are tightly fitted together. Reliably connect the external material supply pipe to the main feed port 104, ensuring a good seal at the connection to prevent material leakage. Then, tightly fit the two ends of the guide die 2 with the discharge die 3 and the main die head 1, and then tighten the screws on the auxiliary plate 6. This allows the auxiliary plates 6 located at the upper and lower ends of the side plate 5 to position the side plate 5, the guide die 2, and the discharge die 3, while the auxiliary plate 6 located on the side of the side plate 5 away from the discharge die 3 positions the side plate 5 and the main die head 1. Through the positioning function of these auxiliary plates 6, the relative positions of each component during operation are ensured to be accurate, improving the coating precision and stability. After positioning, use several screws on the fixing plate 4 to thread them through the fixing plate 4 and connect them to the main mold head 1, the guide mold 2 and the discharge mold 3 respectively, to ensure that all components are tightly connected.

[0038] When the feeding switch is turned on, the raw material for producing the substrate enters the core groove 105 on the opposite side of the upper die head 101 and the lower die head 102 through the main feed port 104. Within the core groove 105, the raw material is compressed, gradually forming a substrate that meets the requirements, providing the base material for subsequent lamination processes. Striped raw material enters through the first feed port 207 and flows through the first coating tank 203 to the guide trough 205. Within the guide trough 205, the raw material is blocked and guided by several stripe plates 206 fixed to the inner surface, gradually forming concave and convex stripes with specific shapes and sizes. At this time, different striped raw materials enter through the second feed port 208, flow through the second coating tank 204 to the guide trough 205, and fill the concave and convex stripes with specific shapes and sizes formed by the raw material in the first coating tank 203, thus producing composite stripes. Simultaneously, because the guide molds 2 are upper and lower layers, composite stripes of different materials can be produced on both sides of the substrate.

[0039] When the substrate produced by the main die head 1 and the composite stripes produced by the guide die 2 enter the discharge die 3 area, the discharge grooves 303 on the opposite sides of the upper discharge die 301 and the lower discharge die 302 extrude the substrate and the composite stripes. Through this extrusion action, the substrate and the composite stripes are tightly bonded together, achieving multi-layer composite.
