Description

Technical Field

[0001] This application relates to the field of printing roller processing technology, and in particular to a sandblasting machine that facilitates the recycling of sand. Background Technology

[0002] Gravure printing is a commonly used printing process, widely applied to various substrates such as plastic film, paper, and composite materials. During the production of the printing rollers, sandblasting is required to create textures on the rollers.

[0003] To avoid sand waste and reduce production costs, sandblasting machines are typically equipped with a recycling mechanism. This mechanism includes a sand collection disc with discharge holes. The collected sand is then discharged from the discharge holes and transported to a storage tank for recycling. However, because the blasting roller has a certain length, the sand collection disc also has a corresponding length. This relatively long disc results in poor centralized discharge efficiency, usually requiring manual assistance, which is cumbersome. Utility Model Content

[0023] Reference Figures 1 to 3 This application provides a sandblasting machine for easy sand recovery, comprising: a base 100 with a clamp 110 for clamping a printing roller; a sandblasting mechanism including a sandblasting head 210 and a feeding assembly, the sandblasting head 210 being disposed on one side of the printing roller with its outlet facing the printing roller, and the feeding assembly being connected to the sandblasting head 210; and a recovery mechanism including a sand collecting disc 310, a spiral rod 320, and a recovery tank 330, the sand collecting disc 310 being disposed below the printing roller, the sand collecting disc 310 including a sand collecting trough 340 and guide plates 350 disposed on both sides of the sand collecting trough 340, the spiral rod 320 being rotatably disposed within the sand collecting trough 340, one end of the sand collecting trough 340 being disposed at a discharge hole 360, the recovery tank 330 being connected to the discharge hole 360, the recovery tank 330 being connected to the feeding assembly, and the recovery tank 330 being provided with a vibrator.

[0024] By installing guide plates 350 on both sides of the sand collecting trough 340, the sand can be concentrated and enter the sand collecting trough 340. Then, the spiral rod 320 inside the sand collecting trough 340 rotates to discharge the sand in the sand collecting trough 340 toward the discharge hole 360, thereby improving the discharge efficiency of the sand collecting trough 340 and eliminating the need for manual operation, thus improving work efficiency. At the same time, by installing a vibrator in the recovery tank 330, the sand can be prevented from clogging the outlet of the recovery tank 330, ensuring that the recovery tank 330 can discharge smoothly and improving the stability and reliability of the operation.

[0025] The bottom of the sand collecting trough 340 is inclined downwards towards the discharge hole 360. By setting the bottom of the sand collecting trough 340 inclined, the discharge of sand in the sand collecting trough 340 can be further improved, thereby increasing the recycling efficiency.

[0026] Reference Figure 1 In this embodiment, a discharge port 370 is provided at the bottom of the recycling tank 330. The discharge port 370 is connected to the feeding assembly. The cross-sectional area of ​​the recycling tank 330 gradually decreases towards the discharge port 360. A vibrator is installed on the side wall of the recycling tank 330 near the discharge port 370. By providing the discharge port 370, the material can be directly discharged and returned to the feeding assembly without manual operation, reducing labor intensity and improving work efficiency. By installing the vibrator on the side wall of the recycling tank 330 near the discharge port 370, the vibration generated by the vibrator can effectively act on the discharge port 370, preventing sand accumulation and blockage at the discharge port 370, and improving the discharge efficiency of the discharge port 370.

[0027] It is conceivable that a cyclone separator 380 is installed above the recovery tank 330, and the cyclone separator 380 is connected to the discharge port 360. The cyclone separator 380 separates and filters the sand, ensuring that the sand entering the recovery tank 330 is clean, thereby guaranteeing the quality of the product reused for sandblasting. Furthermore, a screen 390 is installed between the cyclone separator 380 and the recovery tank 330. Specifically, the screen 390 is located at the top of the recovery tank 330, connected to the recovery tank 330 by a spring, and equipped with a vibrator. The cyclone separator 380 can only separate small particles of debris such as dust, while larger particles will enter the recovery tank 330 with the sand. The screen 390, installed between the cyclone separator 380 and the recovery tank 330, can separate these larger particles, further improving the cleanliness of the recovered sand.

[0028] Reference Figure 1 In some embodiments of this application, a mounting base 120 is slidably disposed on one side of the printing roller, and a mounting plate 130 is flexibly disposed on the mounting base 120. The sandblasting head 210 is disposed on the mounting plate 130. By sliding the mounting base 120 and flexibly displacing the mounting plate 130, the position and height of the sandblasting head 210 can be adjusted, thereby improving the sandblasting quality and efficiency.

[0029] As is readily understood, the feeding assembly includes a storage tank 220 and a compressed air pump 230. The storage tank 220 is equipped with a feeding pipe 240, and the compressed air pump 230 is equipped with an air supply pipe 250. The feeding pipe 240 and the air supply pipe 250 are respectively connected to the sandblasting head 210. By connecting the air supply pipe 250 and the feeding pipe 240 to the sandblasting head 210, the sand and compressed air are mixed in the sandblasting head 210 and then directly sprayed out. This avoids pressure loss caused by friction and collision of the sand in the pipeline, increases the sandblasting pressure of the sandblasting head 210, makes the sandblasting more uniform, and improves the sandblasting quality. Of course, the sand can also be mixed with compressed air before being transported to the sandblasting head 210 through the pipeline; this application does not limit this.

[0030] It is conceivable that the fixture 110 includes clamping components, a first rotary table 140 is rotatably mounted on one side of the machine base 100, a slide block 150 is slidably mounted on the other side of the machine base 100, and a second rotary table 160 is mounted on the slide block 150. The clamping components are respectively mounted on the first rotary table 140 and the second rotary table 160, and the clamping components cooperate to clamp the printing roller. Specifically, the clamping components have a fixing part and a clamping part at both ends. The fixing part is connected to the first rotary table 140 or the second rotary table 160, and the clamping part is set with a conical structure. The printing roller has a shaft hole, and the clamping part is inserted into the shaft hole. By adopting the above structure, it is possible not only to adapt to printing rollers of different specifications, but also to position and center the printing roller, thereby improving sandblasting efficiency and sandblasting quality. It should be noted that the clamping components can also be set as a three-jaw chuck, etc., and those skilled in the art can make reasonable choices according to the actual situation. This application does not limit this.

[0031] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
