Description

Technical Field

[0001] The utility model relates to the technical field of carton punching, in particular to a punching device for carton production. Background Art

[0002] Cartons are the most widely used packaging products. When fruits and vegetables are transported in cartons, they are prone to rot and deterioration due to their characteristics. In order to avoid this, holes are usually punched on the cartons to discharge the gas, moisture and heat generated by the fruits and vegetables to ensure the quality of the fruits and vegetables. Cartons are also usually opened on both sides for easy transportation. However, existing punching machines cannot fix cartons well. Cartons are easy to move during punching, resulting in inaccurate punching positions. The residual materials generated by punching are scattered on the punching platform, which affects subsequent punching operations.

[0026] Example

[0027] like Figure 1-4 As shown, a punching device for carton production includes a support assembly and a guide mechanism 1, a conveying mechanism 2, a punching mechanism 3 and a pushing mechanism 4 arranged on the support assembly. The support assembly includes a support frame 5 and a support rod 6. The support frame 5 is a square frame structure. The conveying mechanism 2 includes two conveying assemblies symmetrically arranged on both sides of the support frame 5. The guide mechanism 1 is arranged on the right side of the conveying mechanism 2. The punching mechanism 3 and the pushing mechanism 4 are arranged on the conveying mechanism 2 from right to left in sequence. The punching mechanism 3 includes a mounting plate 2 31, a rotating roller 1 32, a supporting roller 33 and a motor 34. The mounting plate 2 31 is fixedly arranged on both sides of the conveying mechanism 2. The rotating roller 1 32 and the supporting roller 33 are rotatably arranged on the mounting plate 2 31. The rotating roller 1 32 is located above the conveying mechanism 2, and the supporting roller 33 is located below the conveying mechanism 2. The motor 34 is arranged on the outer side of the mounting plate 1 31 to drive the rotating roller 1 32 to rotate. The outer surface of the rotating roller 1 32 is detachably provided with a cutting mold.

[0028] It is worth noting that the cardboard is guided by the guide mechanism 1 so that the cardboard enters the conveying mechanism 2 vertically, avoiding the cardboard from entering at an angle and causing inaccurate hole positions. The cardboard is driven forward by the conveying mechanism 2, and the punching mechanism 3 is used to punch the cardboard. The punched residual material is separated from the hole by the pushing mechanism 4. Specifically, the frame structure of the support frame 5 avoids the residual material produced by punching to remain on the table and affect the subsequent punching operation. The conveying mechanism 2 conveys the cardboard forward by clamping the two sides of the cardboard, and also avoids the residual material produced by punching to remain on the table and affect the subsequent punching operation. The rotating roller 32 is rotated to make the cutting mold installed thereon punch holes in the cardboard. The support roller 33 is arranged under the rotating roller 32 to support the cardboard and avoid the inability to punch holes.

[0029] In a feasible embodiment, each conveying assembly includes a housing 21, a plurality of upper rollers 23, a mounting seat 24, a plurality of lower rollers 25, an elastic member 26 and a driving assembly. The opposite side walls of the two housings 21 are provided with openings 22 for the carton to pass through. The plurality of upper rollers 23 are rotatably arranged in the upper part of the housing 21. The driving assembly drives the plurality of upper rollers 23 to rotate. The lower roller 25 is rotatably arranged on the mounting seat 24. The mounting seat 24 is arranged at the bottom of the housing 21 and can move up and down through the elastic member 26. The lower roller 25 presses the cardboard upward under the action of the elastic member 26, and the cardboard moves to the left under the drive of the upper roller 23. At the same time, the existence of the elastic member 26 enables the conveying assembly to be applicable to cardboards of different thicknesses.

[0030] In a feasible embodiment, the driving assembly includes a plurality of sprockets 27, a chain 28 and a second motor 29, wherein the sprockets 27 are fixedly arranged on the roller shaft of the upper roller 23, the chain 28 is sleeved on the outside of the plurality of sprockets 27, the second motor 29 is arranged on the outside of the housing 21 of the conveying mechanism 2, and the output end of the second motor 29 is fixedly connected to the roller shaft of the rightmost upper roller 23. The second motor 29 drives the rightmost upper roller 23 to rotate, and the sprocket 27 on its wheel shaft also rotates, driving the chain 28 to move, and the chain 28 drives the remaining sprockets 27 to rotate, thereby driving the remaining upper rollers 23 to rotate together, driving the cardboard to move.

[0031] In a feasible embodiment, the guide mechanism 1 includes a bottom plate 11, a side baffle 12, a mounting plate 13, a conveying roller 14 and a motor 15. The bottom plate 11 is a trapezoidal structure. The short side of the bottom plate 11 trapezoidal structure is fixedly connected to the right end of the conveying mechanism. The side baffles 12 are arranged on the two oblique sides of the bottom plate 22. The mounting plate 13 is fixedly arranged at the bottom of the bottom plate 11. The conveying roller 14 is rotatably arranged on the mounting plate 13. A long hole is opened on the bottom plate 11. The top of the conveying roller 14 passes through the long hole and is flush with the upper surface of the bottom plate 11, which is used to convey the cardboard and send the cardboard into the conveying mechanism 2. The motor 15 is arranged outside the mounting plate 13, and the output end of the motor 15 is fixedly connected to the roller shaft of the conveying roller 14. The two side baffles 12 on the bottom plate 11 play a guiding role, so that the cardboard can enter the conveying mechanism 2 in a state parallel to the conveying mechanism 2.

[0032] In a feasible embodiment, the push mechanism 4 includes a mounting plate 3 41, a rotating roller 2 42 and a motor 43. The mounting plate 3 41 is fixedly arranged on both sides of the conveying mechanism 2. The rotating roller 2 42 can be rotatably arranged on the mounting plate 3 41. The rotating roller 2 42 is located above the conveying mechanism 2. The motor 43 is arranged outside the mounting plate 3 41. The output end of the motor 43 is fixedly connected to the roller shaft of the rotating roller 2 42. The outer surface of the rotating roller 2 42 is provided with a push block with the same shape and position as the cutting mold, but the size of the push block is smaller than the size of the cutting mold, which ensures that the push block is not blocked by the hole on the cardboard during operation and damages the cardboard. The cardboard is transported to the bottom of the push mechanism 4, and the push block on the rotating roller 2 42 can separate the residual material remaining on the hole from the cardboard.

[0033] In particular, it is known that the conveying direction of the conveying mechanism 2 is from right to left. In order to ensure that the punching mechanism 3 and the pushing mechanism 4 do not give the cardboard a rightward force while working normally, the rotation direction of the rotating roller 1 32 and the rotating roller 2 42 should match the conveying direction of the conveying mechanism 2, that is, the transfer roller 1 32 and the transfer roller 2 42 both rotate clockwise.

[0034] It is worth noting that the punching mechanism 3 and the pushing mechanism 4 should work in matching manner, that is, when the cardboard is punched by the punching mechanism 3 and transported to the pushing mechanism 4 by the conveying mechanism 2, the pushing block of the pushing mechanism 4 can be just aligned with the hole punched by the punching mechanism 3.

[0035] In a feasible embodiment, a residual material box 7 is provided below the punching mechanism 3 and the pushing mechanism 4 to collect the residual materials generated by the punching.

[0036] When in use, the cardboard is transported to this device by the conveyor belt of the previous device, and first enters the guide mechanism 1 to align the position of the cardboard. Then, the cardboard enters the conveying mechanism 2 under the action of the conveying roller 14. The conveying mechanism 2 clamps the two sides of the cardboard and conveys it forward. It passes through the punching mechanism 3 and the pushing mechanism 4 in turn, and the cardboard is punched and the residual material produced by the punching falls into the residual material box 7 for collection. The punched cardboard is then transported by the conveying mechanism 2 to the next processing device.

[0037] In addition, it should be understood that although this specification is described in accordance with the implementation methods, not every implementation method contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art. So far, each embodiment of the present disclosure has been described in detail. In order to avoid obscuring the concept of the present disclosure, some details known in the art are not described. Based on the above description, those skilled in the art can fully understand how to implement the technical solution disclosed here.
