Description

Technical Field

[0001] This utility model provides a calender, belonging to the field of rubber product technology, and particularly relates to a calender for producing rubber products. Background Technology

[0002] A calender is an important piece of industrial equipment, widely used in metal processing, building materials, shipbuilding, machinery manufacturing, and many other industries. It primarily uses the pressure of rollers to change the shape and size of metal materials to meet the manufacturing needs of different products. The main difference between a calender used for rubber product manufacturing and a general calender lies in the design of its structure and auxiliary devices, adapted to the characteristics of rubber materials and processing requirements. The design of a rubber calender must consider the calendering effect, that is, the radial and tangential forces exerted on the rollers by the rubber material as it passes through the roller gap, which affects the thickness and quality of the calendered product.

[0003] In the production of rubber products, to avoid the impact of calendering on product quality, the common process involves hot-refining the rubber material before calendering, and then transferring it to the calender for further processing. Hot-refining, also known as preheating or refining, is a pretreatment step in rubber product manufacturing. Its main purpose is to improve the mixing uniformity of the rubber compound and increase its plasticity. While this method can reduce the impact of calendering, it is overly cumbersome and wastes manpower and resources. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this application provides a calender for producing rubber products, which solves the problem that the calendering effect of existing rubber product calenders affects the quality of the products.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a calender for producing rubber products, including a mounting base, wherein the mounting base is provided with a calendering structure, the calendering structure including a drive roller shaft movably mounted in the mounting base, one side of the drive roller shaft is provided with a heating structure corresponding to itself, and the other end of the drive roller shaft is connected to a driven roller shaft corresponding to itself through a gear set of different sizes.

[0006] Preferably, the gear set includes a drive gear connected to the drive roller shaft, and a driven gear that meshes with the drive gear is fixedly connected to the driven roller shaft near the drive gear. The direct drop of the driven gear is greater than that of the drive gear.

[0007] Preferably, the heating structure includes a drive motor located on one side of the drive roller shaft and connected thereto, and an annular heating copper tube is connected to the side of the drive motor near the drive roller shaft via an electrical connector.

[0008] Preferably, the other side of the heating copper tube is provided with a connecting plate that fits into itself, the connecting plate has heat dissipation holes that penetrate itself and correspond to the heating copper tube, and a heating plate is provided below the heat dissipation holes and placed inside the connecting plate.

[0009] Preferably, one side of the heating plate and the driving roller shaft is connected to a connecting ring that is sleeved on its own exterior and fixedly connected to the driving roller shaft via a fixedly connected T-shaped limiting ring.

[0010] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0011] This invention utilizes a calendering structure mounted on a mounting base to perform calendering operations on rubber products using a drive roller and a driven roller. A heating structure on one side of the drive roller directly heats the drive roller, preheating the raw material. This eliminates the need for additional equipment and transfer steps, making it convenient to use. Furthermore, the gear sets of different sizes allow the drive roller and driven roller to rotate at different speeds, further increasing friction and the heat generated during the calendering process. This also extends the time the raw material spends in the calendering process, giving the molecular chains more time to relax and rearrange.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] It should be noted that the terms "vertical," "horizontal," "up," "down," "left," "right," and similar expressions used in this article are for illustrative purposes only and do not represent the only possible implementation.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the description of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0025] like Figure 1 and Figure 2 As shown, a calender for producing rubber products includes a mounting base 1. The mounting base 1 has a calendering structure 2 inside. The calendering structure 2 includes a drive roller 21 movably mounted within the mounting base 1. One side of the drive roller 21 has a heating structure 11 connected to it. The other end of the drive roller 21 is connected to a driven roller 23 corresponding to it via a gear set 22 of varying sizes. The gear set 22 includes a drive gear 24 connected to the drive roller 21. A driven gear 25, meshing with the drive gear 24, is fixedly connected to the end of the driven roller 23 near the drive gear 24. The direct drop of the driven gear 25 is greater than that of the drive gear 22.

[0026] In this embodiment, the present utility model patent relates to a rubber product calendering apparatus, which includes a calendering mechanism 2 mounted on a base 1. The calendering mechanism is equipped with a pair of rollers, a drive roller 21 and a driven roller 23, for performing the calendering process of rubber materials. The drive roller 21 is equipped with a direct heating device 11, which can locally heat the drive roller 21, thereby preheating the rubber raw material, avoiding the need for additional equipment and transfer steps, and improving operational convenience. Furthermore, the calendering mechanism also includes a set of gears 22 of different sizes, the configuration of which allows the drive roller 21 and the driven roller 23 to rotate at different speeds. This speed difference increases the friction between the rollers, thereby generating more heat during the calendering process. Simultaneously, this design also extends the residence time of the rubber raw material during the calendering process, providing more time for the rubber molecular chains to relax and rearrange, thereby improving the quality and performance of the calendered material.

[0027] like Figure 3 and Figure 4 As shown, the rubber product calender of this invention further includes a heating structure 11 designed to heat the drive roller 21. The heating structure 11 consists of a drive motor 12, which is mounted on one side of the drive roller 21 and connected to an annular heating copper tube 14 via an electrical connector 13. The heating copper tube 14 surrounds the drive roller 21 to provide uniform heat. The other side of the heating copper tube 14 is fitted with a connecting plate 15, which is designed with heat dissipation holes 16 that penetrate the connecting plate 15 and correspond to the heating copper tube 14 to ensure effective heat transfer and dissipation. Below the connecting plate 15, a heating plate 17 is provided, which is connected to one side of the drive roller 21 via a fixed T-shaped limiting ring 27 and fixedly connected to the drive roller 21 via a connecting ring 26, thereby heating the drive roller 21. The design of the heating structure allows the drive roller 21 to preheat the rubber raw material during the calendering process, thereby improving production efficiency and product quality. By directly heating the drive roller 21, it can be ensured that the raw material has reached the ideal temperature before entering the calendering area, thereby reducing the dependence on external heating equipment and simplifying the production process.

[0028] In use, this rubber product calender is an integrated heating and calendering device. Its base houses the calendering structure, which includes a drive roller and a driven roller. The drive roller is equipped with a direct heating device to preheat the rubber raw material, improving production efficiency. The drive and driven rollers are connected by gear sets of varying sizes, allowing for different rotational speeds to increase friction and the heat generated during calendering. This extends the residence time of the raw material during calendering, promoting the relaxation and rearrangement of rubber molecular chains, thereby improving the quality and performance of the calendered material. The heating structure includes a drive motor. The equipment includes electrical connectors, annular heating copper pipes, connecting plates, heat dissipation holes, heating plates, and limiting and connecting rings. These components ensure that the drive rollers effectively preheat the rubber raw materials during calendering, reducing reliance on external heating equipment and simplifying the production process. In use, first install and inspect the equipment, then start the drive motor for preheating, adjust the gear set to ensure proper meshing, start the calendering process, input the rubber raw materials, utilize the frictional heat between the rollers and the extended residence time to promote molecular chain rearrangement, and finally output the calendered rubber products. Cleaning and maintenance are then performed to ensure the long-term stable operation of the equipment.

[0029] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the claims.
