Description

Technical Field

[0001] This utility model relates to the technical field of preheating wheel support equipment, specifically a paper preheating wheel support frame. Background Technology

[0002] In the corrugated board production process, the face paper preheating roller support frame is a key piece of equipment. Its main function is to stably support the preheating roller, ensuring that the face paper is fully and evenly preheated before entering the lamination process, thereby improving the forming quality of corrugated board and the efficiency of the production line.

[0003] Currently, these support frames are mostly constructed using welded steel structures or bolted fasteners, exhibiting strong overall integrity but poor local adaptability. Since the specifications of the preheating rollers may be adjusted according to production needs, or the support frames are prone to aging or deformation due to long-term vibration, humid and hot environments, traditional integral structures often struggle with local replacement or adjustment. This leads to prolonged downtime for maintenance, or even complete disassembly, severely impacting production continuity. In particular, replacing the preheating rollers is a frequent occurrence in production. Traditional structures require disassembling and reassembling the bolts at both ends of the preheating roller for replacement, resulting in lengthy replacement times and significant disruption to production continuity.

[0004] In view of this, we propose a support frame for the paper preheating wheel. Utility Model Content

[0005] The purpose of this utility model is to provide a paper preheating wheel support frame, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A paper preheating wheel support frame includes a base, on which a column is detachably connected. A crossbeam is detachably connected to the column via a connecting mechanism. Two mounting brackets are detachably connected to the top of the crossbeam. An mounting mechanism is provided between the crossbeam and the column.

[0007] Preferably, the mounting mechanism includes a rotating seat, which is fixedly installed at the four corners of the crossbeam. A rotating rod is rotatably installed inside the rotating seat, and a hook is fixedly installed at the top of the rotating rod.

[0008] Preferably, multiple locking blocks are fixedly installed at the bottom end of the rotating rod, and multiple locking slots are opened on both sides of the surface of the column, the locking slots being compatible with the locking blocks. Preferably, the connecting mechanism includes a connecting rod and a limiting seat, the limiting seat is fixedly installed inside the column, and the connecting rod and the limiting seat are adapted to each other.

[0009] Preferably, a filling plate is fixedly installed inside the base, column, beam and mounting frame, and the filling plate has a honeycomb structure.

[0010] Preferably, the base, column, beam, and mounting bracket are all hollow open structures, and the filling plate is installed inside the hollow structure of the column, beam, and mounting bracket.

[0011] Preferably, a preheating roller is installed between the two mounting brackets, and a spring is detachably connected between the mounting bracket and the rotating rod.

[0012] By employing the above technical solution, this utility model provides a paper preheating wheel support frame that has at least the following beneficial effects: (1) This utility model divides the support frame into a base, column, crossbeam and mounting frame. At the same time, a quick-release structure and installation mechanism are set between the crossbeam and the column. The quick-release structure can quickly disconnect the connection between the crossbeam and the column. The crossbeam and mounting frame can be quickly replaced by a crane and the installation mechanism. This greatly reduces the replacement time of the preheating roller. The parts are lightweight, so they can be replaced as needed. The parts are of low quality, which can effectively improve maintenance efficiency.

[0013] (2) By setting a filling plate, the high toughness of the honeycomb structure of the filling plate can effectively buffer vibration, and the honeycomb structure is lightweight, which can improve the convenience of subsequent replacement of accessories. Attached Figure Description

[0016] 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.

[0017] Please see Figures 1-6 A paper preheating wheel support frame includes a base 1, a column 2, a crossbeam 3 and a mounting frame 4, and the adjacent structures can be detachably connected, so that the support frame can be disassembled into multiple accessory modules, thereby facilitating the quick replacement and maintenance of each accessory module.

[0018] Please see Figure 2 The base 1 has a square platform structure that is smaller at the top and larger at the bottom, which enhances the stability of the base 1 during operation. A square groove is provided on the top of the base 1 for the insertion and connection of the column 2, improving the connection stability between the base 1 and the column 2. A hollow groove is provided through the top of the column 2, and the bottom of the column 2 has a sealed structure, making the connection between the column 2 and the base 1 more stable and reducing the risk of deformation of the column 2. This also lowers the center of gravity of the column 2, enhancing the stability of the column 2 and the base 1 during operation. Multiple holes are also provided on the surface of the column 2, located in non-load-bearing areas. This effectively reduces the overall weight of the column 2, facilitating subsequent maintenance and replacement. Furthermore, a honeycomb structure with a filling plate 6 is fixedly installed in the hollow part of the column 2 to reduce weight and buffer vibrations generated during operation using the high toughness of the honeycomb structure.

[0019] Preferably, the base 1 and the column 2 are connected by bolts and nuts. When the screw is fixed, a rubber pad or elastic washer is provided between the screw and the surface of the base 1 to buffer and reduce shock. The advantages of using screws and nuts for fixing are high standardization, high connection strength and convenient construction.

[0020] Please see Figure 4 The top of each column 2 is connected to a crossbeam 3. There are two columns 2, arranged symmetrically. The crossbeam 3 connects the two columns 2, making them a unified whole. Reinforcing ribs are provided at the connection between the columns 2 and the crossbeam 3 to enhance the strength and stability of the connection. Furthermore, the crossbeam 3 has a hollow interior filled with a filler plate 6 to reduce weight and buffer vibrations.

[0021] Please see Figure 4 and Figure 5, a connection mechanism 7 is arranged between the upright post 2 and the cross beam 3, the connection mechanism 7 is composed of a connection rod 71 and a limit seat 72, and the connection rod 71 and the limit seat 72 are mutually adapted. The connection mechanism 7 is used for quick disassembly and assembly connection.

[0022] Preferably, the connection rod 71 is a round rod with a magnet, the limit seat 72 is a circular ring with a magnet, and the advantage of magnetic connection is that it can be quickly disassembled and assembled, and can be used for vulnerable parts or parts that need to be replaced frequently. The connection rod 71 is composed of a round rod and a square magnet fixedly mounted at one end of the round rod, one end of the magnet is higher than the surface of the round rod, the upright post 2 and the cross beam 3 are provided with holes and slots adapted to the connection rod 71, the connection rod 71 is slidably connected with the holes and slots, a circular groove is arranged in the upright post 2, the limit seat 72 is fixedly mounted in the circular groove, and the connection rod 71 is not in contact with the limit seat 72. The two ends of the connection rod 71 have different magnetic poles, and the upper and lower ends in the circular ring are provided with different magnetic poles. After the connection rod 71 is inserted into the limit seat 72, the connection rod 71 is rotated by one hundred and eighty degrees under the action of magnetic force, so as to realize automatic limiting of the connection rod 71 and thus achieve the fixing effect. During disassembly, the connection rod 71 can be pulled out by rotating the connection rod 71, which improves the convenience of disassembly and assembly.

[0023] See Figure 2 and Figure 4 , two mounting frames 4 are inserted at the top end of the cross beam 3, the top of the cross beam 3 is provided with a "C"-shaped structure at positions close to both ends, the mounting frame 4 is composed of an I-shaped structure at the top end and a cross rod at the bottom end, and the mounting frame 4 is mutually clamped with the "C"-shaped structure at the top end of the cross beam 3, which can effectively enhance the connection stability between the mounting frame 4 and the cross beam 3, effectively avoid the offset of the mounting frame 4, and the two mounting frames 4 are directly symmetrical after installation, making the subsequent disassembly and assembly of the preheating roll 5 more convenient.

[0024] Preferably, the cross beam 3 and the mounting frame 4 are connected through pins, pin holes and adhesive. The pin connection can bear large shear force and transverse load, which improves the connection stability between the cross beam 3 and the mounting frame 4, avoids the vibration during the operation of the preheating roll 5 from affecting the connection strength, has stable performance under dynamic load, and is suitable for vibration environments.

[0025] See Figure 2 , a preheating roll 5 is detachably connected between the two mounting frames 4, which is used for preheating the face paper to facilitate lamination in the subsequent corrugated board production process.

[0026] See Figure 6, a mounting mechanism 8 is provided between the upright post 2 and the cross beam 3, and the mounting mechanism 8 is used for stable connection between the cross beam 3 and the upright post 2 and quick replacement of the cross beam 3. The mounting mechanism 8 includes a rotating seat 81, the rotating seat 81 is fixedly mounted at the four corners of the cross beam 3, a rotating rod 82 is rotatably mounted in the rotating seat 81, the opening of the rotating seat 81 is in a "C"-shaped structure, and the rotating rod 82 is located inside the "C"-shaped structure, so that the rotating rod 82 can only perform planar rotation along the rotating seat 81 without deviation.

[0027] In this embodiment, a hook 83 is fixedly mounted at the top end of the rotating rod 82. The hook 83 is used for hoisting the cross beam 3. By arranging the hooks 83 at the four corners of the cross beam 3, the hoisting and disassembly of the cross beam 3 are more stable and convenient. During hoisting, the four corners of the cross beam 3 are evenly stressed, the center of gravity is stable, no deviation occurs, and the safety and stability are high.

[0028] In this embodiment, a spring is detachably connected between the mounting frame 4 and the rotating rod 82, so that the spring will not affect the disassembly and assembly between the mounting frame 4 and the cross beam 3, and under the action of the spring force, the rotating rod 82 has a downward rotating force. A plurality of clamping blocks 84 are fixedly mounted at the bottom end of the rotating rod 82, a plurality of clamping grooves 85 are formed on both sides of the surface of the upright post 2, and the clamping grooves 85 are adapted to the clamping blocks 84, so that under the elastic force of the spring, the rotating rod 82 rotates to make the clamping blocks 84 clamped in the clamping grooves 85, so that a triangular structure is formed among the rotating rod 82, the cross beam 3 and the upright post 2, which enhances the connection stability.

[0029] In addition, the clamping block 84 has a triangular structure, and the clamping groove 85 has a square structure, so that when the clamping block 84 is inserted, it contacts the inner top end of the clamping groove 85 to enhance the connection stability, and when being inserted and removed, it will not be blocked by the clamping groove 85, resulting in no motion interference.

[0030] A face paper preheating wheel support frame has the following working principle: The support frame is split into four accessory modules: a base 1, an upright post 2, a cross beam 3 and a mounting frame 4, and adjacent accessory modules are detachably connected, so that the support frame can quickly replace damaged accessories, which can effectively reduce the later maintenance cost. At the same time, each accessory module of the base 1, the upright post 2, the cross beam 3 and the mounting frame 4 has been subjected to weight reduction treatment, by forming grooves or being hollowed out, the weight of the accessories is greatly reduced, which facilitates the improvement of later maintenance efficiency.

[0031] At the same time, filling plates 6 are fixedly installed in the non-stressed hollow structures of each accessory module of the base 1, the upright post 2, the cross beam 3 and the mounting frame 4. The honeycomb structure of the filling plate 6 can effectively buffer the vibration generated during operation, avoiding the phenomenon that the vibration between each accessory module intensifies after modularization, which leads to increased wear.

[0032] When the preheating roller 5 needs to be replaced, first rotate the connecting rod 71 to remove it, thereby releasing the limit between the column 2 and the crossbeam 3. Then, lift the crossbeam 3 by using the hooks 83 at the four corners. When the hooks 83 move upward, under the action of tension, the rotating rod 82 rotates along the rotating seat 81, causing the locking block 84 to disengage from the locking groove 85. This allows the crossbeam 3, along with the mounting frame 4 and the preheating roller 5, to quickly detach. The bottom of the crossbeam 3 is fixedly equipped with rubber wheels to buffer the impact of the crossbeam 3 during transportation and lifting.

[0033] The new crossbeam 3 is then installed into the column 2 by hoisting. When the crane releases the hook 83, the rotating rod 82 rotates along the rotating seat 81 under the action of the spring force, so that the locking block 84 is engaged in the slot 85, thereby connecting the crossbeam 3 and the column 2. The crossbeam 3 is then stably connected by inserting the connecting rod 71, thus completing the replacement operation of the preheating roller 5. Compared with the original method of directly disassembling and assembling the preheating roller 5, the replacement time is greatly reduced, thereby reducing downtime.
