Description

Technical Field

[0001] This utility model relates to a plate press, and more particularly to a roller plate press. Background Technology

[0002] A roller press is a device that uses two or more counter-rotating rollers to extrude, shape, or process materials. It is widely used in industries such as wood processing, plywood production, and building materials.

[0003] The main structure of a roller press includes the following parts: a fixed roller providing stable support; a movable roller controlled by a hydraulic system that can move horizontally and adjust the gap between the two rollers; a frame that bears the extrusion pressure and forms the foundation of the entire equipment; and a hydraulic system that provides high pressure to the rollers, ensuring sufficient pressure on the material between them. The hydraulic system transmits pressure to the movable roller through hydraulic cylinders, creating a high-pressure zone between the two rollers. The core components of the hydraulic system are commonly hydraulic presses or high-power electric motors. These systems have high maintenance costs, demanding production environment requirements, low energy efficiency, and generate significant noise. The production environment during plywood pressing involves a lot of sawdust, which places high demands on the sealing performance of the cold press. The equipment is often large and heavy, resulting in high production costs.

[0004] In order to achieve uniform pressing and conveying of the sheet metal, the existing technology adds a drive motor to one side of the frame and drives the upper and lower rollers to roll through pulleys. Although this method can achieve pressing, the setting of multiple motors increases production energy consumption. In addition, the exposed motors and the connection through pulleys allow impurities to be mixed into the equipment, affecting the service life of the machinery and requiring regular maintenance by staff, which increases labor costs and reduces production efficiency.

[0005] Therefore, based on cost and production needs, the press machine was redesigned using a heavy-duty electric conveyor roller to make it more energy-efficient and effective. Summary of the Invention

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings.

[0022] The specific structure of the roller press described in this utility model is as follows: Figure 1 As shown, the frame 1 includes two horizontally and parallel frames 2 and several support legs 3 fixedly connected to the frames 2 by bolts; the two ends of the roller 4 are fixedly connected to the frames 2 respectively, and the two ends of the electric roller 5 are installed on the frames 2 by locking structures 6. Each electric roller 5 is located above the roller 4 and the central axis of the electric roller 5 and the central axis of the roller 4 are located in the same vertical plane. The plate is located between the rotation of the electric roller 5 and the roller 4, and the several electric rollers 5 and the several rollers 4 form an upper and lower extrusion surface to press the plate together. When the plate enters the extrusion surface formed by the electric roller 5 and the roller 4, the electric roller 5 rotates, driving the plate forward. Since the roller 4 is a non-powered roller, it will also roll in the direction of the plate's forward movement, reducing the resistance of the plate. While promoting the pressing of the plate, the plate is automatically conveyed. It is widely applicable to various production lines.

[0023] like Figure 1 and Figure 5 As shown, the support leg 3 includes a support plate 7 and a support foot 8. The support plate 7 is placed vertically, with its top end connected to the frame 2 via a connecting plate 9. A threaded hole is provided at its bottom end. A threaded rod is welded to the support foot 8, and the support foot 8 is installed at the bottom end of the support plate 7 through the engagement of the threaded rod and the threaded hole. The height of the support foot 8 can be adjusted via the threaded rod, thereby adjusting the height of the frame 2, suitable for the requirements of different production lines. Nuts can be installed above and below the threaded hole to further secure the connection stability between the threaded rod and the support plate 7. The connecting plate 9 can be a triangular connecting plate, a T-shaped connecting plate, etc., depending on the requirements. The connecting plate 9 is mainly used to improve the connection strength between the support plate 7 and the frame 2, thereby providing stable support during the pressing process. A horizontal plate 10 is bolted between adjacent support plates 7. In this embodiment, the horizontal plate 10 is arranged parallel to the roller 4, which can improve the stability of the support plate 7. Furthermore, a crossbeam 11 is also bolted between the two frames 2 to improve the stability of the frames 2.

The connecting shaft 20 is located at both ends of the roller shell 17, and a bearing is provided on each end of the connecting shaft 20 to achieve a rotatable connection with the roller shell 4. The connecting shaft 20 is fixedly connected to the slider 13 by bolts, and the cable enters the roller shell 17 through the connecting shaft 20 and connects to the motor 18. In this embodiment, the connecting shaft 20 is located near the motor 18. Shaft 20 can connect to the housing of motor 18, extending to the outside of drum housing 17, and its diameter decreases in stages to form a stepped shape. At this time, one end of drum housing 17 is the connecting shaft 20, and the other end is the cable connection end. The installation method of the connecting seat and the bearing is as follows: the mounting sleeve is pressed into the drum housing 17, and the mounting sleeve is provided with a mounting groove to load the bearing. The bearing is sleeved on the connecting shaft 20, and then a snap ring is used to install it at the entrance of the mounting groove to limit the bearing. The installation method of the cable connection end and the bearing is as follows: the bearing is sleeved on the cable connection end, and then the mounting sleeve is pressed into the drum housing 17. The mounting sleeve is provided with a mounting groove to load the bearing. At this time, the bearing is limited by the stepped cable connection end.

[0026] like Figure 4 As shown, roller 4 is a non-powered roller, including an outer shell 21, a mounting seat 22 and a mounting shaft 23 located inside the outer shell 21. The mounting seat 22 is located at both ends of the outer shell 21, and the mounting seat 22 is provided with a bearing mounting groove. The bearing is sleeved on the mounting shaft 23 and is aligned and limited by a snap ring. The mounting shaft 23 is located on both sides of the outer shell 21 and is provided with a threaded groove inside.
