Description

Technical Field

[0001] The utility model relates to the technical field of calenders, in particular to a 7-shaped roller structure of a silicone rubber calender. Background Art

[0002] A calender consists of two or more rollers arranged according to the heating method. They can be categorized as cold pressing or hot pressing. Cold pressing is suitable for materials that don't require heating, such as graphite film, graphite sheets, absorbing materials, shielding materials, magnetic materials, and non-ferrous metals. Hot pressing can be further categorized as water-heated, electric-heated, oil-heated, or electromagnetic-heated. All of these machines press and stretch materials such as rubber, silicone, silicone rubber, phase-change materials, PTFE, or plastics into sheets of a specific thickness and surface shape at a specific temperature. They can also coat fiber cords, canvas, or steel cords with glue.

[0003] When traditional calenders on the market are in use, most of their roller structures adopt a horizontally flat upper and lower structure design, which is not convenient for feeding and calendering silicone rubber materials. An additional silicone material feeding and conveying structure is required, which increases the production cost of the machine. At the same time, it is not convenient for thin films to be inserted and bonded, and there are certain limitations in use. For this reason, the utility model proposes a 7-shaped roller structure for a silicone rubber calender. Utility Model Content

[0004] The purpose of the utility model is to provide a 7-shaped roller structure of a silicone rubber calender to solve the problems raised in the above background technology.

[0006] Preferably, a silica gel feed port is fixedly installed with bolts between the top ends of the No. 4 calendering roller and the No. 5 calendering roller and at the top end of the upper frame.

[0007] Preferably, a film-releasing air shaft is installed on the back side of the No. 1 calendering roller and on the upper surface of the tail end of the machine base through fixing bolts.

[0008] Preferably, a conveying wheel is installed between the film-releasing air shaft and the No. 1 calendering roller.

[0009] Compared with the prior art, the beneficial effects of the present invention are:

[0010] The utility model adopts a 7-shaped arrangement of vertical rollers, which has a multiple calendering effect when calendering silicone rubber materials. The silicone rubber material can enter from the top and can be fed and dropped by the friction generated by the rotation of the rollers. In actual use, there is no need to add a feeding drive structure for the silicone rubber material. It is only necessary to set a material guide structure such as a material guide plate between the rollers. It has the effect of automatically unloading the material by the friction generated by the rotation of the rollers, thereby greatly reducing the production cost and design difficulty of the machine.

[0011] At the same time, the vertical unloading method can be more intuitive and convenient to observe and understand the internal rubber material accumulation between the rollers, and it is convenient to timely understand the size of the rubber material accumulation, so as to squeeze and break the bubbles contained in the rubber material, so as to make targeted adjustments and improve the overall calendering quality of the machine. In actual use, the film's film-releasing air shaft and the two rollers at the bottom are arranged horizontally up and down, which makes it convenient for the film to pass through the No. 1 calendering roller and the No. 2 calendering roller when the film-releasing air shaft releases the film, thereby improving the overall use effect.

[0020] Please refer to the instruction manual for details. Figure 2 As shown, the No. 1 calendering roller 4, the No. 2 calendering roller 5, the No. 3 calendering roller 6, the No. 4 calendering roller 7 and the No. 5 calendering roller 8 together constitute a 7-shaped structure of the roller assembly;

[0021] The utility model adopts a 7-shaped vertical roller arrangement. When the silicone rubber material is calendered, the silicone rubber material can enter from the top and fall down by the friction force generated by the rotation of the rollers. In actual use, there is no need to add a feeding drive structure for the silicone rubber material. It is only necessary to set a material guide structure such as a material guide plate between the rollers. It has the effect of automatically unloading the material by the friction force generated by the rotation of the rollers, thereby greatly reducing the production cost and design difficulty of the machine.

[0022] In this embodiment, in order to facilitate the calendering and feeding of silicone rubber material, a silicone feed port 11 is fixedly installed between the top of the No. 4 calendering roller 7 and the No. 5 calendering roller 8 and at the top of the upper frame 2 by bolts. The silicone feed port 11 can be used to feed the silicone rubber material.

[0023] In this embodiment, in order to facilitate the film unwinding process during silicone calendering, a film unwinding air shaft 9 is installed on the back of the No. 1 calendering roller 4 and on the upper surface of the tail end of the machine base 1 through a fixing bolt. The film unwinding air shaft 9 can be rotated to transport the film according to different products in actual use;

[0024] Among them, in order to facilitate the conveying and guiding of the film after film release and improve the conveying tension, a conveying wheel 10 is installed between the film release air shaft 9 and the first calendering roller 4. Figure 3 It can be seen that the film released by the film-releasing air shaft 9 enters between the No. 1 calendering roller 4 and the No. 2 calendering roller 5 through the conveying wheel 10 to be calendered and laminated with the material.

[0025] Working principle: When using this utility model in practice, please refer to the attached manual for details. Figure 1-3 As shown, Figure 3 As shown, the black shadow part at the upper end is the silicone rubber material for calendering, and the outer straight line on the film-releasing air shaft 9 at the bottom is the film. The film is tensioned and conveyed by the conveying wheel 10, and then enters between the No. 1 calendering roller 4 and the No. 2 calendering roller 5 for the final calendering and bonding with the material;

[0026] The silicone rubber material enters from the silicone feed port 11 at the top, and undergoes the initial calendering work when passing between the No. 5 calendering roller 8 and the No. 4 calendering roller 7. Then, it falls through the friction of the roller rotation and enters between the No. 3 calendering roller 6 and the No. 4 calendering roller 7 for the second calendering work. Then, it enters between the No. 3 calendering roller 6 and the No. 2 calendering roller 5 for the third calendering process. Finally, it passes between the No. 1 calendering roller 4 and the No. 2 calendering roller 5 for the final calendering bonding with the film. In actual use, the material can undergo multiple calendering works when entering from the top, which effectively improves the overall calendering effect of the calendering machine.

[0027] The utility model adopts a 7-shaped arrangement of vertical rollers, which has a multiple calendering effect when calendering silicone rubber materials. The silicone rubber material can enter from the top and can be fed and dropped by the friction generated by the rotation of the rollers. In actual use, there is no need to add a feeding drive structure for the silicone rubber material. It is only necessary to set a material guide structure such as a material guide plate between the rollers. It has the effect of automatically unloading the material by the friction generated by the rotation of the rollers, thereby greatly reducing the production cost and design difficulty of the machine.

[0028] At the same time, the vertical unloading method can be more intuitive and convenient to observe and understand the internal material accumulation between the rollers, so as to timely understand the size of the material accumulation, so as to make targeted adjustments and improve the overall calendering quality of the machine. In actual use, the film's film-releasing air shaft and the two rollers at the bottom are arranged horizontally up and down, which makes it convenient for the film to pass through the No. 1 calendering roller and the No. 2 calendering roller when the film-releasing air shaft releases the film, thereby improving the overall use effect.

[0029] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
