[0025] The “width” mentioned in this application refers to Figure 2 The left and right directions are shown.

[0026] This application provides a calendering device for ultra-wide nail surface products, such as... Figure 1 As shown, the calendering equipment 100 is located on the outlet side of the extrusion die 200 and is used to calender the material extruded from the extrusion die 200 into nail-faced products.

[0027] like Figure 1 , 2As shown, the calendering equipment 100 comprises a rack 10, a compression roller set 20 mounted on the rack 10, and a driving mechanism 30, the compression roller set 20 comprises an upper roller 1, a middle roller 2 and a replaceable lower roller 3 arranged in sequence from top to bottom, the upper roller 1, the middle roller 2 and the replaceable lower roller 3 are rotatably mounted on the rack 10, the discharge port of the extrusion die 200 is aligned with the gap between the middle roller 2 and the replaceable lower roller 3, and the material is output from the calendering equipment 100 after winding around the middle roller 2 and the upper roller 1 in sequence from bottom to top in an "S" shape. The driving mechanism 30 comprises a driving motor 4 and a transmission assembly 5, the transmission assembly 5 is connected between the three rollers and the driving motor 4, the driving motor 4 drives the upper roller 1, the middle roller 2 and the replaceable lower roller 3 to rotate at the same speed on the rack 10 through the transmission assembly 5, thereby avoiding uneven tension of the nail surface product, and the transmission assembly 5 can be belt transmission or gear transmission. The width W of the upper roller 1 in the left-right direction is 6500mm-8500mm, the width of the middle roller 2 and the width of the replaceable lower roller 3 are consistent with the width of the upper roller 1, so that the calendering equipment 100 can produce ultra-wide-width nail surface products with a width of 6000mm-8000mm.

[0028] The calendering equipment 100 further comprises a first elevator 40 and a second elevator 50 mounted on the rack 10, the first elevator 40 is in driving connection with the upper roller 1, and the first elevator 40 is used to drive the two end portions of the upper roller 1 to move synchronously in the up-down direction, thereby adjusting the size of the gap between the upper roller 1 and the middle roller 2. The second elevator 50 is in driving connection with the replaceable lower roller 3, and the second elevator 50 is used to drive the two end portions of the replaceable lower roller 3 to move synchronously in the up-down direction, thereby adjusting the size of the gap between the middle roller 2 and the replaceable lower roller 3. The adjustment of the upper roller 1 and the replaceable lower roller 3 by the first elevator 40 and the second elevator 50 makes the calendering equipment 100 applicable to the calendering of products with different thicknesses and ensures the uniform thickness of the products.

[0029] The upper roller 1 and the replaceable lower roller 3 are connected to the rack 10 through a pair of sliding bearing seats 6 respectively, and a sliding assembly 7 is connected between each sliding bearing seat 6 and the rack 10, the sliding assembly 7 comprises a sliding rail 71 extending in the up-down direction and a sliding block 72 in sliding cooperation with the sliding rail 71, the sliding rail 71 is mounted on the rack 10, and the sliding block 72 is connected to the bottom of the sliding bearing seat 6, each sliding bearing seat 6 drives the corresponding roller to move up and down under the interaction between the sliding rail 71 and the sliding block 72, thereby improving the convenience of moving the upper roller 1 and the replaceable lower roller 3 on the rack 10.

[0030] The temperature of the upper roller 1 is set to 10℃-90℃, the temperature of the middle roller 2 is set to 10℃-60℃, and the temperature of the replaceable lower roller 3 is set to 10℃-60℃. The upper roller 1, the middle roller 2, and the replaceable lower roller 3 are connected to a roller temperature control system (not shown in the figure). The roller temperature control system precisely controls the roller surface temperature of each roller, so that the calendering equipment 100 can better calender the product and make the product better detach from the roller surface after calendering.

[0031] In the first embodiment, the upper roller 1 and the replaceable lower roller 3 are mirror rollers, the middle roller 2 is a roller with nail pits on the surface, the material extruded by the extrusion die is calendered between the middle roller 2 and the replaceable lower roller 3, the side facing the middle roller 2 forms a nail surface with multiple protruding nails, and the side facing the replaceable lower roller 3 is a smooth plane, thereby forming a product with a nail surface on one side. The product then passes around the upper roller 1 and is cooled and shaped by the upper roller 1.

[0032] In the second embodiment, the upper roller 1 is a mirror roller, the middle roller 2 and the replaceable lower roller 3 are both rollers with nail pits on the surface. The material extruded by the extrusion die is calendered between the middle roller 2 and the replaceable lower roller 3. The upper and lower surfaces of the product become nail surfaces with multiple protruding nails under the pressure of the nail pits of the rollers, thereby forming a product with nail surfaces on both sides. The product then passes around the upper roller 1 and is shaped under the cooling effect of the upper roller 1.

[0033] In this application, by replacing the lower roller 3, it is possible to produce single-sided and double-sided nailed products, thereby reducing production costs and expanding the applicability of the calendering equipment.

[0034] like Figures 3-5 As shown, multiple nail pits 210 on the intermediate roller 2 are arranged in an array. The depth H of the nail pits 210 is 1.1mm-2.5mm, so that the surface of the product forms a nail portion with a height of 1.1mm-2.5mm in the nail pits 210, enhancing the grip of the nailed surface of the product. In the width direction of the intermediate roller 2, multiple nail pits 210 arranged along a straight line extending in the left-right direction constitute a nail pit group 21. Multiple nail pit groups 21 are provided on the intermediate roller 2, and the multiple nail pit groups 21 are distributed at intervals along the circumference of the intermediate roller 2. In the embodiment of this application, the nail pits 210 of two adjacent nail pit groups 21 are alternately arranged in the width direction. In the width direction, the center distance d1 between two adjacent nail pits 210 in each nail pit group 21 is 3.5mm-6.5mm, and in the circumferential direction, the center distance d2 between two adjacent nail pit groups 21 is 3.5mm-6.5mm. The bottom of each nail pit 210 is conical, which facilitates the detachment of the top formed on the product from the roller. The surface structure of the replaceable lower roller 3 with nail pits is the same as that of the middle roller 2, and will not be described in detail here.

[0035] The calendering equipment of the application can produce the nail surface product with nail parts on one side or the nail surface product with nail parts on both sides by replacing the lower roller, the process is simple, the production cost is low, and the calendering equipment is suitable for producing the ultra-wide nail surface product, and the nail distribution of the nail surface is uniform, the grip is strong, and the thickness of the nail surface product is uniform.
