[0002] Tableting die rollers are components used in the tableting process to compress materials into the required shape and size by applying pressure; traditional die rollers typically employ a single roller structure, which has the following drawbacks:

[0003] First, the roller body is not strong enough and is prone to deformation during long-term high-pressure operation;

[0004] Secondly, the uniformity of the pile pressing area is difficult to control, and the simple grooving structure leads to unstable pile forming effect.

[0005] Third, it has poor heat dissipation performance, and the temperature of the roller increases when running at high speed, which affects the material properties. Utility Model Content

[0006] The purpose of this invention is to provide a stacked mold roller to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a stacked mold roller, comprising an outer roller body, the surface of which is covered with a plurality of velvet sheets stacked and bonded together, a second shaft head fixed to the middle of one end of the outer roller body, and a first shaft head fixedly connected to the middle of the other end of the outer roller body, and a plurality of supporting reinforcing ribs fixedly connected to the end of the first and second shaft heads located inside the outer roller body.

[0008] The supporting reinforcing ribs are evenly distributed along the inner wall of the outer roller body to enhance its structural strength and stability, preventing deformation under long-term high-pressure operation. The fleece sheets are laminated onto the surface of the outer roller body, improving the uniformity of the pressing area and resulting in more stable forming effects and improved sheet quality. Simultaneously, the inclusion of circulating water holes allows cooling water to pass through, further enhancing heat dissipation and ensuring the stability and durability of the die roller during extended operation.

[0009] Preferably, the surface of the outer roller body is provided with multiple retaining strips, and the inner wall of the fleece sheet is provided with multiple sheet slots, with the retaining strips corresponding to the sheet slots.

[0011] Preferably, a circulating water hole is provided in the middle of the second shaft head, and the circulating water hole penetrates the second shaft head and communicates with the interior of the outer roller body. This is used to realize the replacement and circulation of cooling water inside the outer roller body.

[0012] Preferably, a limiting groove is formed on the surface of the shaft head to facilitate the installation and limiting of the shaft head.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The reinforced support ribs significantly enhance the structural strength and stability of the outer roller, effectively preventing deformation under long-term high-pressure operation. Simultaneously, the velvet sheets, laminated onto the outer roller surface, not only improve the uniformity of the pressing area but also ensure more stable forming results, significantly improving the quality of the pressed sheets. Furthermore, the circulating water holes allow cooling water to pass through, effectively enhancing heat dissipation and ensuring the stability and durability of the mold roller during extended operation.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Please see Figure 1-6This utility model provides a stacked mold roller, including an outer roller body 1. The surface of the outer roller body 1 is covered with multiple pile sheets 5. A shaft head 2 4 is fixed to the middle of one end of the outer roller body 1. A shaft head 3 is fixedly connected to the middle of the other end of the outer roller body 1. Multiple supporting reinforcing ribs 6 are fixedly connected to the shaft head 3 and the shaft head 2 4 at the end inside the outer roller body 1.

[0024] Specifically, the supporting reinforcing ribs 6 are evenly distributed along the inner wall of the outer roller body 1 to enhance the structural strength and stability of the outer roller body 1 and prevent deformation under long-term high-pressure operation. The fleece sheet 5 is laminated onto the surface of the outer roller body 1, which not only improves the uniformity of the pressing area but also makes the forming effect more stable and improves the pressing quality. At the same time, the setting of the circulating water holes allows cooling water to pass through, further enhancing the heat dissipation effect and ensuring the stability and durability of the mold roller during long-term operation.

[0025] The outer roller body 1 has multiple clips 101 on its surface, and the inner wall of the fleece sheet 5 has multiple sheet slots 501, with the clips 101 and the sheet slots 501 corresponding to each other.

[0026] Specifically, the design of the locking strip 101 and the sheet slot 501 ensures that the fluffy sheet 5 adheres firmly to the surface of the outer roller body 1, preventing it from falling off or shifting. This design not only enhances the overall structural strength of the mold roller but also guarantees the stability and durability of the fluffy sheet 5 during the pressing process. Furthermore, the precise alignment of the locking strip 101 and the sheet slot 501 ensures that the fluffy sheet 5 is evenly distributed on the surface of the outer roller body 1, thereby further improving the uniformity of the pressing area and the stability of the forming effect.

[0027] The outer roller body 1 has a connecting flange 2 installed on one side of the shaft head 3, and the surface of the connecting flange 2 has multiple fixing holes 201.

[0028] Specifically, the design of the connecting flange 2 allows the mold roller to be easily connected and secured to other equipment or mechanisms. By using bolts or other fasteners through the fixing holes 201, the mold roller can be securely installed on the production line or machinery, ensuring its stability and reliability during operation.

[0029] A circulating water hole 401 is provided in the middle of the shaft head 4, and the circulating water hole 401 passes through the shaft head 4 and communicates with the interior of the outer roller body 1.

[0030] Specifically, the design of the circulating water hole 401 allows cooling water to pass through and circulate inside the mold roller, effectively carrying away the heat generated by high-speed operation and thus greatly reducing the temperature of the roller body. This design not only improves the heat dissipation performance of the mold roller but also ensures that the material properties do not change due to high temperatures during the pressing process, further enhancing the quality and stability of the product.

[0031] A limiting groove 301 is provided on the surface of the shaft head 3.

[0032] Specifically, the limiting groove 301 is designed to cooperate with the corresponding limiting structure to ensure the stability and accuracy of the shaft head 3 during installation or use. This design prevents the shaft head 3 from shifting or rotating when subjected to external forces, thereby ensuring the overall stability and pressing accuracy of the mold roller.

[0033] In practical use, the mold roller is connected and fixed to other equipment or mechanisms via the connecting flange 2. The equipment is then started, and the mold roller begins to operate. During the pressing process, the fluffy flakes 5 are evenly distributed on the surface of the outer roller body 1, ensuring the uniformity of the pressing area and the stability of the forming effect. Simultaneously, the supporting reinforcing ribs 6 enhance the structural strength and stability of the outer roller body 1, preventing deformation under long-term high-pressure operation. Cooling water circulates inside the mold roller through the circulating water holes 401, effectively carrying away the heat generated by high-speed operation, reducing the roller body temperature, and ensuring that the material's properties do not change due to high temperatures during pressing. Furthermore, the limiting groove 301 ensures the stability and accuracy of the shaft head 3 during installation or use, preventing offset or rotation. The entire mold roller structure is compact and rationally designed, improving the tableting quality and production efficiency, meeting the needs of industrial production.

[0034] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
