Embodiment 1

[0038] Packing bag burr-free rounding device, basically as attached figure 1 As shown, it includes a hollow workbench 1 and a support arranged above the workbench 1 . Two limit plates 3 are arranged on the upper surface of the workbench 1, and the two limit plates 3 are arranged in parallel, and the working surfaces of the limit plates 3 are arranged oppositely; The hinge is hinged with a baffle plate 4. When the baffle plate 4 is vertically arranged, magnet layers are arranged on opposite sides, and the two magnet layers attract each other. The two baffle plates 4 and the two limit plates 3 form a square Place cavity.

[0039] combine figure 2 As shown, the upper surface of the workbench 1 is located at the four corners of the placement cavity and is provided with an arc-shaped receiving port 11 and four chutes 12 respectively connected to the receiving port 11, and the chute 12 is arranged horizontally. In the groove 12, there is a material blocking plate 2 which is hori...

Embodiment 2

[0048] Embodiment 2 differs from Embodiment 1 only in that, as Figure 5 , Figure 6 As shown, the grinding part in the present embodiment includes a grinding wheel 6, the chamfering knife 54 is hollow, and the grinding wheels 6 are arranged in multiple rows from top to bottom, and the grinding surface of the grinding wheel 6 and the inner arc of the chamfering knife 54 The surfaces are coplanar, and a rotating shaft 7 is coaxially fixed on the grinding wheel 6 , and a section of the rotating shaft 7 principle grinding wheel 6 is connected to the chamfering knife 54 in rotation. Specifically, the outer arc surface of the hollow chamfering knife 54 is provided with a rotating hole matched with the rotating shaft 7, and the rotating shaft 7 is rotatably connected in the rotating hole. The adjacent grinding wheels 6 of each row of grinding wheels 6 are in close contact; the adjacent rotating shafts 7 of each row are driven by a belt. Gear 71 is fixed on the rotating shaft 7 of ...

Abstract

The invention belongs to the technical field of deflashing or deburring equipment and discloses a packaging bag burr-free corner rounding device. The packaging bag burr-free corner rounding device comprises a working table and a rack arranged on the working table, and further comprises chamfering knives and cylinders for driving the chamfering knives to move. A moving disk is fixed to output shafts of the cylinders. A telescopic rod is fixed to the middle of the moving disk. A locating disk is fixed to the bottom of the telescopic rod. The locating disk is provided with four arc-shaped chamfering holes. The chamfering holes are located in the positions, close to the four vertex angles, of the locating disk. The four arc-shaped chamfering knives are further arranged on the moving disk and are located over the four chamfering holes correspondingly. The chamfering knives can pass through the corresponding chamfering holes. The inner arc surface of each chamfering knife is provided with agrinding part. Through the packaging bag burr-free corner rounding device, the problem that burrs exist at chamfered places after completion of chamfering in the prior art is solved.

Description

technical field [0001] The invention belongs to the technical field of equipment for removing burrs or flying burrs, and in particular relates to a burr-free rounding device for packaging bags. Background technique [0002] Packaging bag refers to the bag used to pack various items. In order to prevent moisture and water, plastic packaging bags are usually used. After the plastic packaging bags are processed, they are usually square, and the top corners are very sharp, which is easy to cause users Scratched, so the top corners need to be rounded. The existing chamfering device usually includes a workbench and a support arranged above the workbench. The workbench is provided with a rotating disk, and the support is provided with a cylinder connected with a chamfering knife. When in use, stack the packaging bag on the rotating disk, and make one of the top corners under the chamfering knife, start the motor, and the motor drives the chamfering knife to move down to realize th...
