[0021] In the above technical scheme, the first driving assembly 3 is provided to drive the U-shaped frame 12 to slide left and right on the workbench 1, thereby driving the punching assembly 2 to slide left and right; by providing the punching assembly 2, the punching knife 204 is driven up and down by the cylinder 201 to punch and remove the edge waste part of the freezing box; by providing the limit assembly 4, it can be used to limit the position of the freezing box on the workbench 1, so as to facilitate the removal of the edge waste part; by providing the second driving assembly 5, the limit assembly 4 can be driven to rotate on the workbench 1, thereby achieving the purpose of driving the freezing box to rotate on the workbench 1, and facilitating the all-round edge waste removal operation of the freezing box. Compared with the method of removing the edge waste of the freezing box by a cutter in the prior art, the utility model adopts the punching removal method, which will not generate particulate dust during the removal process, will not affect the working environment, and is beneficial to the health of the staff.

[0022] In the utility model, the punching assembly 2 includes a cylinder 201, which is installed on the top of the U-shaped frame 12. Slide grooves 202 are provided on the adjacent two side surfaces inside the U-shaped frame 12. Mounting columns 203 are slidably connected between the slide grooves 202. The bottom of the mounting column 203 is detachably connected to a punching knife 204. The output end of the cylinder 201 is threadedly connected to the top of the mounting column 203.

[0023] In the above technical solution, by slidingly connecting the mounting column 203 in the slide groove 202, it can be limited during the punching and sliding up and down process, and by detachably connecting the punching knife 204 to the bottom of the mounting column 203 with bolts, it is convenient to replace and maintain the punching knife 204. When in use, the air intake of the cylinder 201 can drive the mounting column 203 to move downward in the slide groove 202. The downward movement of the mounting column 203 drives the punching knife 204 to move downward, thereby punching and removing the waste on the edge of the freezer body.

[0024] In the utility model, the first driving component 3 includes a first motor 301, which is fixedly mounted on the front end surface of the L-shaped mounting plate 8. A first gear 302 is provided on the output shaft of the first motor 301. A mounting platform 303 is provided on the front end surface of the workbench 1. A rack 304 is provided on the top of the mounting platform 303. The first gear 302 is meshed with the rack 304.

[0025] In the above technical solution, by setting the first motor 301, the rotation of the first motor 301 can drive the first gear 302 to rotate. Since the first gear 302 meshes with the rack 304, the first gear 302 can move on the rack 304 during rotation, thereby achieving the purpose of driving the U-shaped frame 12 and the punching assembly 2 to move left and right on the top of the workbench 1.

[0026] In the utility model, the limit assembly 4 includes a rotating shaft 401, a bearing chamber 402 is opened in the top of the workbench 1, a bearing 403 is arranged in the bearing chamber 402, the rotating shaft 401 is passed through the inner ring of the bearing 403, the rotating shaft 401 is rotatably connected to the workbench 1 through the bearing 403, a cross-shaped connecting rod 404 is arranged on the top of the rotating shaft 401, and the outer ring of the connecting rod 404 is fixedly connected to the limit frame 405.

[0027] In the above technical solution, the rotating shaft 401 is rotatably connected to the workbench 1 by the bearing 403, so that the rotating shaft 401 and the workbench 1 are rotatably connected, and then the limit frame 405 can be rotatably connected to the workbench 1. When placing the freezer box, the freezer box is turned upside down on the position of the limit frame 405, which can limit the freezer box to prevent it from moving, making it convenient to punch and remove the edge waste.

[0028] In the utility model, the second driving assembly 5 includes a connecting member 501, which is detachably connected to one side of the bottom of the workbench 1. A second motor 502 is installed at the bottom of the connecting member 501. A second gear 503 is connected to the output shaft of the second motor 502. The rotating shaft 401 passes through the workbench 1 and extends to the bottom of the workbench 1. The rotating shaft 401 extends to the bottom of the workbench 1 and is connected to a driven gear 504, which meshes with the second gear 503.

[0029] In the above technical solution, the second motor 502 is connected to the bottom of the workbench 1 by using a connecting piece 501, and the second gear 503 is connected to the output shaft of the second motor 502. When the edge waste on the two parallel sides of the freezing chamber is cut and removed by the punching knife 204, the second motor 502 rotates to drive the second gear 503 to rotate, and then drives the driven gear 504 meshing with it, so as to drive the rotating shaft 401 to rotate. The rotation of the rotating shaft 401 can drive the limit frame 405 and the freezing chamber to rotate to punch and remove the remaining edge waste on the two parallel sides of the freezing chamber.

[0030] The working principle of the refrigeration box punching device of the utility model is:

[0031] When in use, the freezer body is turned upside down in the position of the limit frame 405, and the first motor 301 rotates to drive the first gear 302 to rotate. During the rotation of the first gear 302, it moves on the rack 304, thereby driving the U-shaped frame 12 and the punching assembly 2 to move toward the edge to be removed from the freezer body. When it moves to the cutting position, the cylinder 201 intakes air to drive the mounting column 203 to move downward in the slide slot 202. The mounting column 203 moves downward to drive the punching knife 204 to move downward to punch and remove the edge waste of the freezer body. After that, the cylinder 201 exhausts air to drive the punching knife 204 to return to its original position, and the first motor 301 is started again, driving the punching assembly 2 and the U-shaped frame 12 to cut the edge of the freezer body for the first time. The first motor 301 stops rotating, and the punching knife 204 can punch and remove the waste material on this edge of the freezing box driven by the cylinder 201. After the removal is completed, the cylinder 201 exhausts air to drive the punching knife 204 to retract. Finally, the second motor 502 rotates to drive the second gear 503 to rotate. The rotation of the driven gear 504 can drive the rotating shaft 401 and the freezing box inverted outside the limit frame 405 to rotate. When the remaining unpunched sides of the freezing box rotate to the position corresponding to the punching knife 204, the second motor 502 stops rotating, and the edge waste on the remaining unpunched sides of the freezing box can be punched and removed.

[0032] It is worth noting that: in the present invention, the first motor 301 and the second motor 502 are electrically connected to the external power supply through the controller, which belongs to the prior art, so the present invention does not make too many elaborations; the inlet and outlet air of the cylinder 201 is controlled by the control valve on the external air circuit, and the control valve is also electrically connected to the external power supply through the controller, which also belongs to the prior art and is not made too many elaborations in the present invention.

[0033] This article uses specific examples to illustrate the principles and implementation methods of the utility model. The above examples are only used to help understand the method and core ideas of the utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
