The application fields of color-printed packaging boxes are very wide, including electronics, food, beverages, alcohol, tea, cigarettes, medicine, health products, cosmetics, small household appliances, clothing, toys, sporting goods and other industries and product packaging supporting, etc. As people's requirements for the appearance and quality of goods continue to increase, the application of color-printed packaging boxes in the field of commodity packaging is becoming more and more extensive.

[0003] In the prior art, such as Chinese patent number: CN113953889A, a cooling device and a CNC machine tool are provided, including a CNC machine tool and a shell arranged at the chip removal port of the CNC machine tool, and also including: a grinding component arranged in the shell, which is used to grind the debris; a suction component movably arranged in the shell, which is used to support the debris generated by the processing, and the suction component keeps reciprocating motion with the rotation of the grinding component; a driving component arranged in the shell, which is used to drive the grinding component to rotate, and the suction component sucks the debris into the grinding component through reciprocating motion. In the cooling device and CNC machine tool provided by the present invention, the suction component keeps reciprocating motion inside the shell, sucks the debris outside the shell into the shell, and drives the grinding component to rotate through the driving component inside the shell, grinds and cuts the long strip debris into short strips or granules, so as to reduce the blockage of the coolant recovery pipeline, and the rubber layer arranged on the top of the suction component can increase the suction force of the coolant.

An inner cooling groove 42 is opened inside the grinding head 41, and a heat conduction plate 43 is fixedly connected to the inner wall of the inner cooling groove 42. An annular embedding groove 44 is opened on the top of the grinding head 41, and the outer wall of the annular driving plate 38 is driven to rotate inside the annular embedding groove 44. A group of air holes A45 are opened at the bottom of the inner wall of the grinding head 41, and a linkage rod 46 is fixedly installed at the bottom of the inner wall of the grinding head 41. Four inner channels 47 are opened inside the linkage rod 46, and the output ends of the four inner channels 47 are connected to the inside of the air hole A45.

The protection mechanism 1 includes a protection box 11, and the inner wall of the protection box 11 is fixedly inserted with a support platform 12, and the bottoms of the two horizontal drive components 21 are fixedly connected to the top of the support platform 12.

[0044] In the present embodiment, firstly, under the mutual transmission inside the pushing mechanism 2, the linkage assembly 24 can be moved between the horizontal, longitudinal and vertical positions, so that the cooling mechanism 3 can be adjusted in position to meet the position requirements of workpiece cutting and grinding, and in this process, the rotating motor 63 can drive the gear body 64 at its front end to rotate when powered on, and the gear body 64 and the tooth groove 83 produce meshing transmission. When the rotating plate 82 is driven to rotate and cooperates with the rotating groove 72, the workpiece clamped on the top can be effectively rotated, thereby meeting the position adjustment of the work.

[0045] The working principle of the whole mechanism is as follows: first, the components to be processed are placed on the top of the rotating disk body 81, and then, driven by the four cylinders B85, the clamping plates 86 are pushed forward respectively (the inner slide bar 87 is embedded and moved in the inner moving groove 84), so that the components to be processed can be clamped by the four clamping plates 86, and the workpiece can be kept in a stable state. Under the mutual transmission inside the pushing mechanism 2, the linkage component 24 can be moved horizontally, longitudinally and vertically, so that the cooling mechanism 3 can be adjusted to meet the position requirements for cutting and grinding the workpiece. In this process, the rotating motor 63 can drive the gear body 64 at its front end to rotate when it is powered on. In addition, the gear body 64 and the tooth groove 83 produce meshing transmission. When the rotating plate 82 is driven to rotate and cooperate with the rotating groove 72, the workpiece clamped on its top can be effectively rotated, thereby satisfying the working position rotation. Then, with the cylinder A61 as the power, it can push the front end linkage plate 62 and the components fixed thereto to move forward and backward while maintaining its own elasticity (under the cooperation of the two slide plates 76 respectively slidingly embedded in the slide groove 52), so as to adjust the position relationship between the fixed disk mechanism 7 and the rotating disk mechanism 8. At this time, the rotating motor 63 is powered on, and electromagnetics are generated inside itself, while the rotor keeps rotating, so that the gear body 64 at the front end maintains rotation and enables it to mesh with the inside of the tooth groove 83. The transmission is combined, and the rotating plate 82 is rotated and embedded in the rotating groove 72 to cooperate, which can keep the rotating disk mechanism 8 as a whole to rotate, so as to meet the position adjustment of the device in the cutting and grinding state. When moving, the driving motor 31 is powered on, and its output end keeps rotating. The grinding head 41 at the bottom contacts the outer wall of the workpiece during the movement, so as to complete the grinding and cutting of the outer wall of the workpiece. During the grinding and cutting process, the external refrigeration equipment can cool the gas, and then use the pipeline A35 as a conveying path to transfer the gas to the inside of the one-way gas introduction valve 34, and then transfer it to the inside of the half space isolated inside the fixed ring 32, and maintain it through the one-way gas introduction valve 34. Continue to pressurize such space to maintain a certain pressure value, and when the linkage rod 46 rotates, during the rotation process, when each group of air holes B48 is connected with such space, the low temperature in such space can enter the interior of the inner channel 47 through the air holes B48, and then the low-temperature gas is transferred to the interior of the inner cooling groove 42 through the air holes A45 at the bottom. The heat conduction plate 43 can transfer the heat generated by the grinding head 41 itself to the inside, and contact and mix with the cold gas inside it. Then, on the other side, when the linkage rod 46 rotates to the other side, the fixing ring 32 is aligned with another space isolated by the two inner isolation plates 33. Under the absorption of the one-way exhaust valve 36 itself, this space can be kept in a negative pressure state.Thus, the mixed gas inside the inner cooling groove 42 is extracted and transferred to the space in the adsorption state, and finally the gas can be transported outward through the one-way exhaust valve 36, and the gas is discharged through the pipeline B37, so that the gas can flow inside it, thereby completing the heat dissipation treatment. When grinding the workpiece, the four groups of air nozzles 75 on the top can be aligned with the processing position, so that the chips from cutting and grinding can be blown away to avoid the problem of accumulation of chips and affecting subsequent processing.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
