Description

Technical Field

[0001] This utility model relates to the field of stone-plastic composite board production technology, specifically to a stone-plastic composite board polymer sheet calendering and shaping device. Background Technology

[0002] Calendering is one of the core technologies for manufacturing polymer films and sheets. It relies on precise control of roller temperature and speed to ensure that the material reaches the ideal plasticity and elongation state during the calendering process. This technology is particularly suitable for the processing needs of thermoplastic materials such as stone-plastic composite boards. As an emerging environmentally friendly building material, stone-plastic composite boards have won wide application in many fields such as building decoration and furniture manufacturing due to their lightweight, high strength, excellent weather resistance and convenient processing characteristics. In the production process of polymer sheets, the calendering and shaping step of stone-plastic composite boards is crucial, as it directly affects the flatness, thickness consistency and final overall performance of the product.

[0003] The calendering and shaping device, with its core component, the calendering roll, plays a crucial role in the entire production process. The main function of the calendering roll is to apply a certain pressure and stretching force to the heated and softened stone-plastic composite polymer sheet through its rolling action, so as to achieve the expected thickness and flatness. The power source for this process mainly depends on the gear transmission system closely connected to it.

[0004] In the calendering and shaping device for SPC polymer sheets, the fixed-gap calendering rollers rely on gears to transmit kinetic energy. However, traditional lubrication methods, such as external oil circuits or manual periodic grease application, have obvious defects. These methods often result in uneven lubrication, making it difficult for grease to evenly cover the gear meshing surfaces. This problem is particularly prominent under high-speed and heavy-load conditions, where insufficient local lubrication not only exacerbates tooth surface wear and causes tooth surface damage but also reduces transmission efficiency and stability. Therefore, a calendering and shaping device for SPC polymer sheets is proposed to address the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a calendering and shaping device for high-polymer sheets of stone-plastic composite board, so as to solve the obvious defects of traditional lubrication methods such as external oil circuits or manual periodic grease addition. These methods often lead to uneven lubrication, and the grease is difficult to evenly cover the gear meshing surface. Especially under high-speed and heavy-load conditions, the problem of insufficient local lubrication is particularly prominent. This will not only aggravate tooth surface wear and cause tooth surface damage, but also reduce transmission efficiency and stability.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

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.

[0028] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0029] Please see Figure 1-6 This utility model provides a technical solution:

[0030] A calendering and shaping device for stone-plastic composite sheet polymer material includes a support platform 1. A bracket 2 is fixedly connected to one side of the upper surface of the support platform 1. Two calendering rollers 3 are rotatably connected to the inner side of the bracket 2. A transmission assembly 4 is fixedly connected to one end of each calendering roller 3. The two transmission assemblies 4 are meshed together. The transmission assembly 4 includes a gear 41. A lubricating grease collection groove 42 is formed on the front end face of the gear 41. An oil collection groove 43 and a distribution hole 44 are formed at the root of the gear 41. The distribution hole 44 is located in the middle of the oil collection groove 43. The bottom of the surface is provided with a micro-groove 45, and a protective mechanism 46 is installed on one side of the gear 41. The protective mechanism 46 includes a protective cover plate 461, a blade 462 is fixedly connected to the outer side of the protective cover plate 461, and a mounting plate 463 is fixedly connected to the side of the protective cover plate 461 corresponding to the gear 41. The outer side of the mounting plate 463 is engaged with the inner side of the lubricating grease collection groove 42, and a sealing ring 464 is engaged with the inner side of the mounting plate 463. The sealing ring 464 fits against the lubricating grease collection groove 42. This arrangement is used to improve the sealing performance.

[0031] As a further implementation of this scheme, the cross-sectional shape of the distribution hole 44 is triangular, and the inner side of the oil collection groove 43 is connected to the inner side of the lubricating grease collection groove 42 through the inner side of the distribution hole 44. The triangular cross-sectional shape of the distribution hole 44 can enhance the structural strength of the gear 41.

[0032] As a further implementation of this solution, four micro-grooves 45 are opened at the bottom of each tooth surface of the gear 41. The four micro-grooves 45 are arranged radially and equidistantly around the distribution hole 44. The micro-grooves 45 are located above the oil collection groove 43, and the inner side of the micro-grooves 45 is connected to the inner side of the oil collection groove 43. The radial micro-grooves 45 can evenly distribute the lubricating grease on each tooth surface of the gear 41, forming a thin lubricating film. This lubricating film can significantly reduce the friction coefficient between the gears 41, reduce wear and heat generation.

[0033] As a further implementation of this solution, the front end face of the protective cover plate 461 is provided with three first heat dissipation grooves 465, which are equidistantly arranged in a circular pattern. The gear 41 is provided with a second heat dissipation groove 47 in the middle. There are three second heat dissipation grooves 47, and the positions of the second heat dissipation grooves 47 correspond to the positions of the first heat dissipation grooves 465. The inner side of the first heat dissipation groove 465 is connected to the inner side of the second heat dissipation groove 47.

[0034] As a further implementation of this solution, the protective cover plate 461 has an installation groove 466 in the middle that is compatible with the calendering roll 3. A fixing seat 467 is fixedly connected to one side of the installation groove 466. The fixing seat 467 is connected to the calendering roll 3 by fixing bolts 468. This setting is convenient for installation and also convenient for adding lubricating grease to the lubricating grease collection groove 42 later.

[0035] As a further implementation of this solution, a motor 5 is fixedly connected to the side of the bracket 2 away from the transmission component 4. The transmission shaft of the motor 5 is fixedly connected to the other end of the calendering roller 3 located below, and the motor 5 provides power for the rotation of the calendering roller 3.

[0036] Workflow: This SPC polymer sheet calendering and shaping device is powered by an external power source. The drive shaft of the motor 5 drives the calendering rollers 3 connected to it to rotate synchronously. The two transmission components 4 use gears 41 to mesh, causing the two calendering rollers 3 to rotate relative to each other. To improve the local lubrication effect of the calendering rollers 3, before use, an appropriate amount of synthetic grease is added to the lubricating grease collection tank 42 and evenly spread. This synthetic grease has a high viscosity. Then, the protective cover plate 461 is installed through the mounting groove 46. 6. Mounted on the calendering roller 3, the mounting plate 463 on one side of the protective cover plate 461 is inserted into the inner side of the lubricating grease collection groove 42. The sealing ring 464 is used to improve the sealing effect at the joint. A fixing hole for fitting the fixing bolt 468 is opened at the front end of the calendering roller 3. By tightening the fixing bolt 468 on the surface of the fixing seat 467, the protective cover plate 461 is fixed. When the calendering roller 3 on the bracket 2 starts to calender the stone-plastic composite polymer sheet, it is driven by the motor 5, and the two gears 41 rotate accordingly. Due to the lubricating grease... The grease collection groove 42 is pre-stored with lubricating grease, and the inner side of the grease collection groove 42 is connected to the inner side of the oil collection groove 43 through the inner side of the distribution hole 44. The inner side of the oil collection groove 43 is connected to the micro-grooves 45 opened on the tooth surface. Therefore, when the gear 41 rotates, centrifugal force is generated, and the radial micro-grooves 45 can evenly distribute the lubricating grease on each tooth surface of the gear 41, forming a thin lubricating film. This lubricating film can significantly reduce the coefficient of friction between the gears 41, reduce wear and heat generation, thereby improving the performance of the gears 41. In terms of transmission efficiency and stability, during the rotation of gear 41, the positions of the first heat dissipation groove 465 and the second heat dissipation groove 47 correspond, and the inner sides of the first heat dissipation groove 465 and the second heat dissipation groove 47 are connected. This design promotes air circulation and can cool down gear 41. In addition, multiple blades 462 are provided on the outer side of the protective cover plate 461. These blades 462 generate airflow when rotating with the calendering roller 3. The airflow can be used to cool down the tooth surface of gear 41, which helps to improve the service life of gear 41.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
