Description

Technical Field

[0001] The utility model belongs to the technical field of transmission rollers, and particularly relates to a transmission roller for the production of film-coated anti-sticking paper. Background Art

[0002] In the field of composite material and prepreg manufacturing, as a key auxiliary material, the performance of film-coated anti-sticking paper is directly related to the smoothness of the prepreg processing process and the quality of the final product. In the traditional production process of film-coated anti-sticking paper, as a core component, the transmission roller is responsible for continuously and stably conveying the anti-sticking paper, but faces a major challenge: due to the special chemical and physical properties of the film formed by the film-coating liquid on the outer surface of the anti-sticking paper, it is not easy to quickly cool and solidify. Coupled with the frictional heat generated by the long-time and high-speed operation of the transmission roller, the surface temperature of the roller body rises sharply. This phenomenon not only accelerates the softening of the film-coating liquid, but also increases the adhesion force between the transmission roller and the anti-sticking paper, which is extremely easy to cause the anti-sticking paper to adhere to the surface of the roller body, seriously affecting the production efficiency and product quality, increasing the maintenance cost, and even causing the production line to interrupt.

[0003] At present, although some cooling devices have been applied to the transmission roller system in the market, they generally have problems such as low cooling efficiency, high energy consumption, complex structure and inconvenient maintenance, and are difficult to fully meet the high-efficiency, stable and environmental protection requirements in the production process of film-coated anti-sticking paper. Therefore, there is a certain market demand for developing a transmission roller for the production of film-coated anti-sticking paper that can cool the roller body and effectively avoid the sticking phenomenon. Summary of the Invention

[0004] In view of the above deficiencies of the prior art, the utility model provides a transmission roller for the production of film-coated anti-sticking paper to solve the above problems.

[0005] A transmission roller for the production of film-coated anti-sticking paper of the utility model includes a roller body. A plurality of support partitions are arranged on the roller body in an axial rotation array. A plurality of sections of heat dissipation sleeves are sleeved outside the support partitions of the roller body. Plugging grooves corresponding to the support partitions one by one are arranged on the inner circumferential wall of the heat dissipation sleeve. A duct is formed by every two support partitions and the inner circumferential wall of the heat dissipation sleeve. A stainless steel sleeve is sleeved on the heat dissipation sleeve. Threaded ends are arranged at both ends of the roller body. An impeller is coaxially screwed on each of the two threaded ends, and the blades of the two impellers face in opposite directions. The inner ends of the impellers abut against the end faces of the heat dissipation sleeve and the stainless steel sleeve, and annular ventilation grooves are arranged at the inner ends of the impellers. An installation rod is arranged at the outer end of each threaded end.

[0006] Further, a plurality of limiting chutes are arranged on the outer circumferential wall of the heat dissipation sleeve in an axial rotation array. Limiting sliders corresponding to the limiting chutes one by one are arranged on the inner circumferential wall of the stainless steel sleeve.

[0007] Further, a number of groups of heat dissipation fins are arranged in an axial rotation array on the inner circumferential wall of the heat dissipation sleeve, and each group of heat dissipation fins corresponds to a ventilation duct one by one.

[0008] Further, the heat dissipation sleeve is an aluminum alloy sleeve.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] In order to better understand the present utility model, the following will be combined with Figures 1 to 6 to explain the embodiments of the present utility model in detail.

[0021] It should be noted that the "front, rear, left, right, up, and down" directions described in the text are all based on the Figure 1 "front, rear, left, right, up, and down" directions in

[0022] See Figures 1 to 6 A driving roller for the production of laminated anti - sticking paper according to the present utility model includes a roller body 1. A plurality of support partitions 2 extending outward are rotationally arranged along the axial direction on the outer peripheral wall of the roller body 1. A plurality of heat dissipation sleeves 3 are sleeved around the support partitions 2 of the roller body 1. Insertion slots 4 corresponding to the support partitions 2 one by one are designed on the inner peripheral wall of the heat dissipation sleeve 3. Through the cooperation of the insertion slots 4 and the support partitions 2, a closed air duct 5 is formed by every two support partitions 2 and the inner peripheral wall of the heat dissipation sleeve 3. In order to improve the heat dissipation efficiency of the air duct 5, a plurality of groups of heat dissipation fins 13 are also rotationally arranged on the inner peripheral wall of the heat dissipation sleeve 3. Each group of heat dissipation fins 13 corresponds to the air duct 5 one by one. The design of the heat dissipation fins 13 can increase the contact area between the air and the roller body 1 and the heat dissipation sleeve 3, and improve the heat exchange efficiency.

[0023] Threaded ends 7 are provided at both ends of the roller body 1. Impellers 8 are coaxially screwed onto the threaded ends 7, and the blades of the two impellers 8 face in opposite directions. This design makes it so that when the driving roller rotates, the two impellers 8 rotate in opposite directions, one impeller 8 sucks air, and one impeller 8 discharges air, thereby generating a self - rotating air - guiding effect, sucking in external cold air and passing it through the heat dissipation fins 13 in the air duct 5 to cool the roller body 1 and the heat dissipation sleeve 3. The inner ends of the impellers 8 abut against the end faces of the heat dissipation sleeve 3 and the stainless - steel sleeve 6, and annular ventilation grooves 9 are provided, which are used to connect the air duct 5 and the impellers 8 to form an air flow path.

[0024] Considering the firmness between the heat dissipation sleeve 3 and the stainless - steel sleeve 6, a plurality of limiting sliding grooves 11 are rotationally arranged on the outer peripheral wall of the heat dissipation sleeve 3 along the axis, and corresponding limiting sliding blocks 12 are arranged on the inner peripheral wall of the stainless - steel sleeve 6. Their cooperation enables the stainless - steel sleeve 6 to be stably sleeved on the heat dissipation sleeve 3, while ensuring a small gap between the two for air circulation.

[0025] In order to further enhance the heat conduction performance, a layer of thermal conductive adhesive is provided between the inner peripheral wall of the stainless - steel sleeve 6 and the outer peripheral wall of the heat dissipation sleeve 3. The thermal conductive adhesive can quickly transfer the heat on the roller body 1 and the heat dissipation sleeve 3 to the stainless - steel sleeve 6 and dissipate it into the environment through air cooling.

[0026] In order to ensure the heat dissipation ability of the heat dissipation sleeve 3, the heat dissipation sleeve 3 is preferably an aluminum alloy sleeve.

[0027] For ease of assembly, as Figure 6 shown, chamfers are designed at both ends of the support partition 2 to reduce the frictional resistance during the insertion process.

[0028] In order to reduce material usage and facilitate the discharge of internal hot air, the roller body 1 is designed as a hollow rod.

[0029] The usage method and principle of the present utility model:

[0030] When using the drive roller for the production of the coated anti-sticking paper of the present invention, first install it at an appropriate position on the production line to ensure that the drive roller can rotate stably. With the start of the production line, the drive roller starts to rotate, driving the two impellers 8 to rotate synchronously. One of the impellers 8 is used to draw air into the air duct 5, and the other impeller 8, due to the opposite orientation of the blades, does not produce an air-drawing effect and is used to discharge the cold air after entering the air duct 5. The external cold air is inhaled and passes through the heat dissipation fins 13 in the air duct 5 to efficiently cool the roller body 1 and the heat dissipation sleeve 3. At the same time, the thermal conductive adhesive between the stainless steel sleeve 6 and the heat dissipation sleeve 3 quickly transfers the heat to the surface of the stainless steel sleeve 6, further accelerating the heat dissipation process. In this way, the sticking problem caused by heat generation due to friction of the drive roller is effectively avoided, ensuring the smooth progress of the production of the coated anti-sticking paper.
