Description

Technical Field

[0001] This application relates to the technical field of gravure printing roller processing, and in particular to a gravure printing roller welding platform. Background Technology

[0002] The gravure printing roller includes a printing roller cylinder and end caps. The end caps are first inserted into both ends of the printing roller cylinder by interference fit. In order to prevent the end caps from detaching, the end caps need to be welded and fixed to the printing roller cylinder.

[0003] The existing gravure printing roller welding platform includes a working platform and two circular support rollers mounted on the working platform. When the gravure printing roller is placed between the two circular support rollers, it remains stationary, and the welding equipment welds the gravure printing roller.

[0004] Regarding the aforementioned technologies, after welding, the two ends of the gravure printing roller are quite hot, making it inconvenient for manual handling and removal. Since the two circular support rollers have a positioning effect, it is difficult to directly push the gravure printing roller away; the entire gravure printing roller needs to be lifted up, which is quite laborious. Utility Model Content

[0005] To address the aforementioned issues, this application provides a gravure printing roller welding platform.

[0006] This application provides a gravure printing roller welding platform, which adopts the following technical solution:

[0007] A gravure printing roller welding platform, comprising:

[0008] The work platform is equipped with mounting grooves;

[0009] Multiple support portions are sequentially arranged and installed within the mounting grooves;

[0010] A spring is used to support the support portion, and the upper end of the spring is fixedly connected to the support portion.

[0011] By adopting the above technical solution, the spring-supported support part can adapt to different parts of the gravure printing roller and provide stable support. After welding, by pressing down or moving all the support parts up, the contact between the support parts and the gravure printing roller is reduced, and the gravure printing roller can be easily removed from the welding platform, which improves the problem that it is relatively difficult to move the gravure printing roller after welding in the prior art.

[0012] Optionally, the support portion is a cylindrical structure.

[0013] By adopting the above technical solution, the cylindrical support structure can better contact the gravure printing roller, provide uniform support force, reduce the shaking of the gravure printing roller during the welding process, and improve the welding quality.

[0014] Optionally, the support is fixedly connected to a guide rod, and the working platform is equipped with a guide plate on the inner wall of the mounting groove. The guide plate has a guide groove for the guide rod to slide up and down.

[0015] By adopting the above technical solution, the stability of the support part during the up-and-down movement can be ensured through the cooperation of the guide rod and the guide plate, preventing the support part from shifting during the movement, and further improving the stability of the welding platform and the welding quality.

[0016] Optionally, the lower end of the spring is fixedly mounted on the guide plate, and the spring and the guide rod are coaxially sleeved.

[0017] By adopting the above technical solution, the coaxial sleeve design of the spring and guide rod can ensure the stability of the spring during compression and extension, reduce the spring's offset and torsion during the stress process, and improve the service life of the spring and the stability of the welding platform.

[0018] Optionally, it also includes a top plate and a drive source for moving the top plate up and down. The drive source is located outside the work platform, and the top plate is located within the mounting groove and below the guide plate. When the top plate moves upward, it drives the guide rod to move upward, thereby driving the downward-moving support portion to move upward.

[0019] By adopting the above technical solution, the design of the top plate and drive source can facilitate the reset of the support part, reduce the contact between the support part and the gravure printing roller, and further facilitate the removal of the gravure printing roller; this design also improves the automation level of the welding platform and reduces manual operation.

[0020] Optionally, the top plate is provided with a socket, and when the guide rod moves downward, the guide rod is inserted into the socket.

[0021] By adopting the above technical solution, the design of the insertion hole can improve the positioning effect of the guide rod during the descent process, prevent the guide rod from deviating during the descent process, and further improve the stability of the welding platform and the welding quality.

[0022] Optionally, a pad is provided at the center of the top plate, and the bottom of the insertion hole of the pad is higher than the bottom of the insertion hole on the top plate.

[0023] By adopting the above technical solution, when the top plate moves upward and drives the support part to move upward, the support part located in the middle position is higher than the support parts on both sides. The stepped distribution of the support parts can guide the gravure printing roller to move downward, making the gravure printing roller more stable when leaving the welding platform, reducing the shaking and collision of the gravure printing roller during the leaving process, and improving the service life of the gravure printing roller and the welding quality.

[0024] Optional, also includes:

[0025] The feed plate is inclined, and its inclined lower end is fixedly installed on the working platform, near the mounting groove.

[0026] The discharge plate is inclined and its upper end is fixedly installed on the working platform, close to the other side of the mounting groove.

[0027] By adopting the above technical solution, the inclined feed plate and discharge plate can utilize gravity to make the gravure printing roller smoother when placed and removed, reducing the difficulty and labor intensity of manual handling.

[0028] In summary, this application includes at least one of the following beneficial effects:

[0029] 1. After welding is completed, the gravure printing roller can be easily removed from the welding platform by pressing down the support part or using the top plate to drive the support part to reset, which solves the problem in the prior art that the gravure printing roller is hot to the touch and difficult to move after welding.

[0030] 2. The stepped distribution of the support section, as well as the cooperation of the guide plate and guide rod, further optimizes the positioning and support of the gravure printing roller on the welding platform, reduces the shaking, collision and damage of the gravure printing roller during welding and removal, and protects the integrity and surface quality of the gravure printing roller.

Detailed Implementation

[0036] The following is in conjunction with the appendix Figure 1 -Appendix Figure 4 This application will be described in further detail.

[0037] This application discloses a gravure printing roller welding platform.

[0038] Reference Figure 1 A gravure printing roller welding platform includes a working platform 10 with a mounting groove 11. The length of the mounting groove 11 is shorter than the length of the gravure printing roller. Multiple support parts 20 are sequentially installed within the mounting groove 11. These support parts 20 are used to directly contact the gravure printing roller and provide support. When the gravure printing roller enters the mounting groove 11, both ends of the roller are located outside the working platform 10, facilitating welding at both ends of the roller.

[0039] Reference Figure 1 and Figure 2 The support part 20 is designed as a cylindrical structure. The length direction of the cylindrical structure is the same as that of the gravure printing roller. The length of the cylindrical support part 20 is shorter than that of the gravure printing roller. The cylindrical structure can better fit the surface of the gravure printing roller, providing uniform and stable support force, thereby reducing the shaking of the gravure printing roller during the welding process and improving the welding quality.

[0040] Reference Figure 2 To achieve elastic support for the support section 20, each support section 20 is connected to a row of springs 30. The springs 30 are compression springs, and their upper ends are fixedly connected to the support section 20. When the gravure printing roller slides into the mounting groove 11 and simultaneously contacts multiple support sections 20, the multiple support sections 20 will compress the springs 30 according to different parts of the gravure printing roller, forming adaptive support. Simultaneously, to ensure the stability of the support section 20 during vertical movement, each support section 20 is also fixedly connected to a guide rod 40. To ensure the guide rod 40 can move smoothly up and down, a guide plate 50 is fixedly installed in the mounting groove 11, and the guide plate 50 has guide grooves for the guide rod 40 to slide up and down. The cooperation between the guide rod 40 and the guide grooves allows the support section 20 to maintain linear movement during movement, preventing deviation.

[0041] Spring 30 is sleeved on guide rod 40, and the lower end of spring 30 is fixedly installed on guide plate 50. The coaxial sleeve design of spring 30 and guide rod 40 can ensure the stability of spring 30 during compression and extension, reduce the offset and torsion of spring 30 during the stress process, and improve the service life of spring 30 and the stability of welding platform.

[0042] Reference Figure 2Below the support 20, a top plate 60 and a drive source 70 for moving the top plate 60 up and down are also provided. The top plate 60 is located within the mounting groove 11 and below the guide plate 50. The drive source 70 is located outside the working platform 10 and drives the top plate 60 to move up and down within the mounting groove 11 mechanically or electrically. In this embodiment, the drive source 70 is an electric telescopic rod. The top plate 60 is provided with a socket 61. When the guide rod 40 moves downward too far, it will be inserted into the socket 61, thereby improving the positioning effect of the guide rod 40.

[0043] Reference Figure 2 and Figure 3 In addition, a pad 62 is provided in the middle of the top plate 60, and the bottom of the insertion hole 61 on the pad 62 is higher than the bottom wall of the insertion hole 61 on the top plate 60. When the top plate 60 moves upward and the pad 62 abuts against the lower surface of the guide plate 50, the top plate drives the support part 20 to move upward, and all the guide rods 40 are inserted into the insertion hole 61. Due to the action of the pad 62, the support part 20 located in the middle position will be higher than the support parts 20 on both sides, reducing the contact between the support part 20 and the gravure printing roller. At the same time, the support part 20 also forms a stepped distribution. This distribution method can guide the gravure printing roller to move downward smoothly after welding, reducing shaking and collision.

[0044] Reference Figure 4 The welding platform also includes an inclined feed plate 80 and an inclined discharge plate 90. The lower inclined end of the feed plate 80 is fixedly installed on the working platform 10 near the mounting groove 11. An inclined conveyor belt is installed near the feed plate 80 to transport the gravure printing roller. The upper inclined end of the discharge plate 90 is fixedly installed on the working platform 10 near the mounting groove 11. The other end of the discharge plate 90 is connected to a receiving platform 91. This design utilizes gravity, allowing the gravure printing roller to slide in automatically when placed. When removed, the stepped support 20, in conjunction with the downwardly inclined discharge plate 90, allows it to slide smoothly away from the mounting groove 11, reducing the difficulty and labor intensity of manual handling.

[0045] The implementation principle of a gravure printing roller welding platform according to an embodiment of this application is as follows:

[0046] In actual operation, as the gravure printing roller slides into the mounting groove 11 through the feed plate 80, the sliding direction and speed of the gravure printing roller can be manually controlled to ensure that the gravure printing roller accurately falls into the mounting groove 11. Outside the mounting groove 11, multiple support parts 20 press down on the springs 30 to varying degrees according to the shape and weight of the gravure printing roller, forming a stable support. After welding, the top plate 60 is moved upwards by pressing down on the support parts 20 or by using the drive source 70. The stepped distribution of the support parts 20 guides the gravure printing roller away, and the gravure printing roller then slides out of the welding platform through the discharge plate 90. Throughout the process, stable support and convenient removal of the gravure printing roller are ensured, while reducing shaking and damage during welding and removal, protecting the integrity and surface quality of the gravure printing roller.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
