Description
Technical Field
[0001] This utility model relates to the field of pressure roller structure, and in particular to a pressure roller structure for a plate press. Background Technology
[0002] Currently, Chinese utility model patent CN220241763U discloses a pressure roller structure for a plate pressing machine. While the upper roller in this structure can be adjusted up and down via a motor, other problems exist during use. For example, it is inconvenient to remove the roller for inspection and maintenance; the roller's surface wears down after prolonged use, making removal difficult. It requires removing the inspection plate and using tools to tap both ends of the roller to remove it from the bearings, increasing the workload. Furthermore, it cannot automatically adjust the upper roller over short distances. Although driven by a motor, the downward distance is difficult to control; excessive downward movement increases pressure on the material plate, resulting in poor flexibility. To address these problems, we propose a pressure roller structure for a plate pressing machine. Utility Model Content
[0003] The purpose of this invention is to provide a pressure roller structure for a plate press, which solves the problems of existing pressure roller structures being inconvenient to disassemble and assemble and unable to automatically adjust the upper pressure roller over short distances.
[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a pressure roller structure for a plate press includes two frames, with an upper pressure roller and a lower pressure roller respectively arranged between the two frames. Both ends of the upper and lower pressure rollers are secured with fixed seats. A fixing bolt is threaded through the top of each fixed seat, and a nut threadedly connected to the fixing bolt is embedded in the bottom of the fixed seat. Two first connecting blocks and a second connecting block are rotatably connected to the other side of the four fixed seats. A lifting mechanism is provided at the bottom of the second connecting block. A cylinder is bolted through the top of the frame, and a fixed cylinder is installed at the piston end of the cylinder. A sliding block is provided inside the fixed cylinder. A connecting rod is installed between the bottom of the sliding block and the first connecting block, and a fixing spring is installed between the top of the sliding block and the fixed cylinder.
[0005] The above technical solution enables short-distance automatic adjustment of the upper pressure roller, improving the pressing effect on the material plate, reducing the adjustment burden on personnel, providing good flexibility, facilitating the disassembly and assembly of the roller, simplifying and facilitating operation, improving the efficiency of personnel inspection and maintenance, and demonstrating high practicality.
[0006] The present invention is further configured such that: the lifting mechanism includes a threaded rod, the bottom end of the threaded rod is rotatably connected to the inside of the frame through a bearing, the surface of the threaded rod is threadedly connected to a threaded sleeve that is bolted to the second connecting block, and a connecting piece is fixedly sleeved on the surface of the threaded rod.
[0007] By adopting the above technical solution, and through the setting of threaded rods, threaded sleeves and connecting parts, the distance between the top of the lower pressure roller and the sliding roller of the pressure machine can be adjusted after the equipment is fixed to the table of the pressure machine, thereby improving the applicability of the equipment.
[0008] The present invention is further configured such that: mounting plates are welded to both the front and back of the frame, and mounting holes are provided inside the mounting plates.
[0009] By adopting the above technical solution, the mounting plate and mounting holes make it easy for personnel to fix the frame with screws, reducing the trouble of personnel drilling holes temporarily.
[0010] The present invention is further configured such that the fixing base, fixing bolt and nut are all made of stainless steel.
[0011] Using the above technical solution, the fixing seat, fixing bolt and nut have the characteristics of high strength, low density and excellent corrosion resistance.
[0012] The present invention is further configured such that a damper is installed between the top of the sliding block and the fixed cylinder.
[0013] By adopting the above technical solution, the damper can be used to suppress the jumping of the fixed spring, consume the kinetic energy stored in the fixed spring, and improve stability.
[0014] The present invention is further configured such that the fixing spring is made of carbon spring steel.
[0015] Using the above technical solution, the fixed spring has the characteristics of excellent mechanical properties, good anti-elasticity, low temperature resistance and corrosion resistance.
[0016] In summary, this utility model has the following beneficial effects: 1. This utility model first fixes the frame to the press machine with screws. After the frame is fixed, the connecting part is rotated to move the lower press roller to the appropriate position. Then, the cylinder is started to drive the fixed cylinder to move downward. When the fixed cylinder moves downward, it will drive the first connecting block to move downward together. When the first connecting block moves downward, it will drive the upper press roller to contact the top of the material plate. When the fixed cylinder continues to move downward, it will push the connecting rod and the sliding block to retract into the interior. After the sliding block retracts, it will compress the fixed spring and the damper to make it contract. This allows for short-distance automatic adjustment of the upper press roller, improves the pressing effect on the material plate, reduces the adjustment burden of personnel, and has good flexibility. 2. This utility model allows for easy disassembly and assembly of the roller when it is damaged. The fixed bolts on the fixed seats at both ends of the roller are grasped with a tool and rotated. During rotation, the fixed bolts move upward and separate from the inside of the nut below. After the fixed bolts are loosened, they can be pulled upward directly from the upper pressure roller and the fixed seat. Then, the upper pressure roller can be pulled out directly. This makes it easy to disassemble and assemble the roller, and the operation is simple and convenient. It improves the efficiency of personnel inspection and maintenance and has high practicality.

Two first connecting blocks 7 and second connecting blocks 8 are rotatably connected to the other side of the four fixed seats 4. A lifting mechanism 9 is provided at the bottom of the second connecting block 8. When the roller is damaged, the fixing bolts 5 on the fixed seats 4 at both ends of the roller are grasped with a tool and rotated. During rotation, the fixing bolts 5 move upwards and separate from the interior of the lower nut 6. Once the fixing bolts 5 are loosened, they can be pulled upwards directly from the upper pressure roller 2 and the fixed seat 4, and then the upper pressure roller 2 can be pulled out directly. This facilitates the disassembly and assembly of the roller, is simple and convenient to operate, improves the efficiency of personnel inspection and maintenance, and has high practicality.

The surface of the threaded rod 91 is threadedly connected to a threaded sleeve 92 that is bolted to the second connecting block 8. A connecting piece 93 is fixedly sleeved on the surface of the threaded rod 91. With the arrangement of the threaded rod 91, the threaded sleeve 92 and the connecting piece 93, the distance between the top of the lower pressure roller 3 and the sliding roller of the pressure machine can be adjusted after the equipment is fixed to the table of the pressure machine, thus improving the applicability of the equipment.
[0022] refer to Figure 1 Mounting plates 15 are welded to both the front and back of the frame 1. Mounting plates 15 have mounting holes inside. The mounting plates 15 and mounting holes make it easy for personnel to fix the frame 1 with screws, reducing the trouble of personnel drilling holes temporarily.
[0023] refer to Figure 1 and Figure 3 The fixing seat 4, fixing bolt 5 and nut 6 are all made of stainless steel. The fixing seat 4, fixing bolt 5 and nut 6 have the characteristics of high strength, low density and excellent corrosion resistance.
[0024] Brief description of the usage process: When the roller is damaged, use a tool to grasp the fixing bolts 5 on the fixing seats 4 at both ends of the roller and rotate them. When rotating, the fixing bolts 5 will move upward and separate from the inside of the nut 6 below. When the fixing bolts 5 are loose, pull them directly upward from the upper pressure roller 2 and the fixing seat 4. Then pull the upper pressure roller 2 directly outward.
[0025] Example 2: refer to Figure 1 and Figure 2 A pressure roller structure for a plate press includes a cylinder 10 bolted through the top of a frame 1.

After the frame 1 is fixed, the connecting piece 93 is rotated to move the lower pressure roller 3 to a suitable position. Then, the cylinder is started. The cylinder 10 drives the fixed cylinder 11 to move downward. When the fixed cylinder 11 moves downward, it will drive the first connecting block 7 to move downward together. When the first connecting block 7 moves downward, it will drive the upper pressure roller 2 to contact the top of the material plate. When the fixed cylinder 11 continues to move downward, it will push the connecting rod 13 and the sliding block 12 to retract into the interior. After the sliding block 12 retracts, it will press the fixed spring 14 and the damper 16 to make it contract. This allows for short-distance automatic adjustment of the upper pressure roller 2, which improves the pressing effect on the material plate, reduces the adjustment burden on personnel, and provides good flexibility.

[0028] Brief description of the operation process: Fix the frame 1 to the press machine with screws. After the frame 1 is fixed, rotate the connecting piece 93 to move the lower pressure roller 3 to the appropriate position. Then start the cylinder 10 to drive the fixed cylinder 11 to move downward. When the fixed cylinder 11 moves downward, it will drive the first connecting block 7 to move downward together. When the first connecting block 7 moves downward, it will drive the upper pressure roller 2 to contact the top of the material plate. When the fixed cylinder 11 continues to move downward, it will push the connecting rod 13 and the sliding block 12 to retract into the interior. After the sliding block 12 retracts, it will press the fixed spring 14 and the damper 16 to make it contract.
