Description

Technical Field

[0001] This utility model relates to the field of welding technology, specifically a welding machine for printing roller processing. Background Technology

[0002] Welding is a process that uses heat or pressure to join two separate metal objects together through the bonding forces between atoms. Welding is usually done using a welding machine, which can join two metal objects by melting parts of the two metal parts together at high temperatures.

[0003] The welding machine still has some shortcomings, such as increasing production time when replacing the printing plate roller:

[0004] To overcome the problem of low efficiency in changing printing rollers, a prior art Chinese patent (publication number: CN116984825A) discloses a welding device and welding method for the bending point of a printing roller. The welding frame that slides relative to each other on the base plate can fix the two ends of the printing roller to accommodate printing rollers of different lengths. The welding positioning plate can position the diameter of the printing roller. Then, by adjusting the distance between the welding gun clamp and the welding positioning plate, the position of the bending point of the printing roller is positioned, thereby achieving the purpose of welding printing rollers of different diameters. This saves the time of changing different types of welding frames and welding gun clamps, thus greatly improving the efficiency of printing roller welding production.

[0005] However, the welding machines currently in use still have certain shortcomings. In the aforementioned document, the welding machine uses the weight of the roller itself for clamping and positioning. When the device is running, it may be affected by other surrounding objects, and the welding machine may vibrate. Vibration will affect the stability of clamping, thereby affecting the quality of welding. Therefore, there are certain shortcomings in its use, and the existing structure needs to be improved.

Detailed Implementation

[0030] 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.

[0031] Example 1, such as Figures 1-4 The technical solution shown in this utility model provides the following technical solution: To solve the problem of unstable fixing of the printing roller by the welding machine, a locking mechanism is disclosed: including a base 1, with a support frame 2 and a welding assembly 3 respectively connected to the upper surface of the base 1. The support frame 2 is symmetrically distributed about the center of the base 1, and a rotating assembly 4 is connected inside the support frame 2: a rotating block 201 is symmetrically rotatably connected to the top of the support frame 2, a rubber wheel 202 is connected to the top of the rotating block 201, and a ratchet 203 is connected to one side of the rotating block 201. The ratchet 203 rotates inside a rotating groove 204, which is symmetrically opened on the support frame 2. Inside the support frame 2, a locking mechanism is provided to facilitate the fixing of the rollers; an extension block 207 slides through the rotating block 201, and an adjustment mechanism is provided on the top of the rotating block 201 to improve the adaptability to different specifications of printing rollers. The locking mechanism includes a rotating block 214, which rotates through the support frame 2 near the ratchet 203. A torsion spring connects the rotating block 214 and the support frame 2. A rotating frame 205 is fixed to the end of the rotating block 214. The end of the rotating frame 205 away from the rotating block 214 moves through the support frame 2, and the rotating frame 205 is in close contact with the side of the ratchet 203 teeth.

[0032] When the welding machine processes the printing roller, the distance between the two support frames 2 is adjusted according to the length of the printing roller. Then, the printing roller is placed on the top inner side of the support frame 2 by the equipment or other means. The welding component 3 is then moved to the position of the printing roller to be welded for welding. During the welding process, the printing roller can be rotated by the rotating component 4. Stable welding can be completed by rotation. Before welding, the printing roller needs to be fixed. When fixed, the rotating block 201 can be rotated by the support frame 2. When the rotating block 201 rotates, it can drive the rubber wheel 202 to rotate. When the rotating block 201 rotates, it can drive the ratchet 203 to rotate. When the ratchet 203 rotates, it can rotate through the rotating groove 204. When the ratchet 203 rotates, the meshing inclined surface on the side can squeeze the rotating frame 205. When the rotating frame 205 is squeezed, it can drive the rotating block 214 to rotate. When the rotating block 214 rotates, it can rotate through the support frame 2. When rotating, the torsion spring can be tightened through the support frame 2. When rotating block 214 rotates, it can drive rotating frame 205 to rotate slightly inside the support frame 2. When rotating frame 205 rotates to the side of the ratchet 203, ratchet 203 can rotate through rotating groove 204. When rotating block 201 drives rubber wheel 202 to rotate to the side of the printing roller at the top of support frame 2, it can be squeezed. When rubber wheel 202 squeezes, rotating block 214 can be reset through the torsion spring. When rotating block 214 is reset, it can drive rotating frame 205 to be reset. When rotating frame 205 is reset, it can rotate to the plane of ratchet 203 for positioning. When ratchet 203 is positioned, it can drive rubber wheel 202 to be positioned. At this time, rubber wheel 202 can squeeze and position the printing roller. In the same way, the other sets of rubber wheels 202 squeeze and position the printing roller. After the printing roller is positioned, it can rotate more stably through rubber wheel 202, reducing vibration and improving the welding quality of the welding machine.

[0033] Example 2, as follows Figure 5 The present invention provides the following technical solution to address the inconvenience and operational issues associated with the rotating block 201 of the welding machine during use: Based on Embodiment 1, a reset mechanism is disclosed.

[0034] Both sides of the rotating block 201 are fixed with first fixing blocks 206, which rotate through the rotating groove 204. A ratchet 203 is fixed to the end of the first fixing block 206 on one side of the rotating block 201. A torsion spring connects the first fixing block 206 and the rotating groove 204. A reset mechanism to improve the operating efficiency of the rotating block 201 is provided on the surface of the first fixing block 206. When the welding machine fixes the printing roller, it needs to rotate the rotating block 201. When the rotating block 201 rotates, it can drive the first fixing block 206 to rotate. When the first fixing block 206 rotates, it can rotate the first fixing block 206 to rotate. When the groove 204 rotates, the first fixed block 206 can tighten the torsion spring through the rotating groove 204. As the rubber wheel 202 squeezes the printing roller, the torque on the first fixed block 206 will increase. After the printing roller is welded, the rotating frame 205 is rotated by hand to rotate the rotating frame 205 out of the meshing plane of the ratchet 203. After the rotating frame 205 is no longer positioned, the torsion spring can drive the first fixed block 206 to reset. When the first fixed block 206 resets, it can drive the rotating block 201 to reset. There is no need to reset the printing roller separately, which improves the efficiency of the welding machine operation.

[0035] Example 3, as follows Figure 2 , Figure 3 , Figure 6 and Figure 7 The present invention provides the following technical solution to address the problem that welding machines are inconvenient for welding rollers of different specifications: Based on Embodiment 1, an adjustment mechanism is disclosed:

[0036] The adjustment mechanism includes a second fixing block 208, which is fixed to the top of the extension block 207. A rubber wheel 202 is rotatably connected to the inner side of the second fixing block 208. Limiting grooves 209 are symmetrically opened on both sides of the extension block 207. Limiting blocks 210 slide through the limiting grooves 209. The limiting blocks 210 are symmetrically fixed inside the rotating block 201. Four sets of through grooves 211 are opened on the side of the rotating block 201 away from the limiting blocks 210. The extension block 207 is close to the through grooves 211. A telescopic groove 212 is provided on the side of 1. A locking block 213 slides through the telescopic groove 212. A spring connects the locking block 213 and the telescopic groove 212. The locking block 213 and the through groove 211 are locked together. When the welding machine positions the larger size printing roller for welding, pulling up the second fixing block 208 can drive the extension block 207 to move. When the extension block 207 moves, it can drive the limiting groove 209 to move. When the limiting groove 209 moves upward, it can slide through the limiting block 210. The extension block 207 can cause the inclined surface of the locking block 213 to press against the inner wall of the through groove 211. When the locking block 213 is pressed, it can slide through the telescopic groove 212. When the locking block 213 slides, it can press the spring. After the locking block 213 is pressed out of the through groove 211, the extension block 207 can slide through the inside of the rotating block 201. When the second fixing block 208 slides to the required height, it can drive the locking block 213 to move to the side of another through groove 211. At this time, the locking block 213 can be reset by the elastic force of the spring. When the locking block 213 is reset, it can be inserted into the through groove 211 for positioning. When the locking block 213 is positioned, it can drive the second fixing block 208 to be positioned. When the second fixing block 208 is positioned, it can drive the top rubber wheel 202 to be positioned, changing the height of the rubber wheel 202, thereby facilitating the fixing of larger-sized printing rollers, improving the adaptability of the welding machine to different-sized printing rollers, and improving the ease of use of the welding machine.

[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
