Description

Technical Field

[0001] The utility model mainly relates to the technical field of bubble bag processing, in particular to a cutting device for bubble bags. Background Art

[0002] Bubble bags are mainly made of high-pressure polyethylene bubble film, which is cut into the required bag-making specifications and sizes. They are mainly used for cushioning packaging of electronic products, logistics and transportation protection of plastic products, metal products, ceramic products, glass products and other products that require cushioning protection.

[0003] As disclosed in patent authorization number CN202123178503.2, a bubble bag cutting device includes a bubble bag cutting machine, a telescopic support leg is installed at the bottom of the bubble bag cutting machine, a workbench is installed on the top of the telescopic support leg, a groove is opened on one side of the bubble bag cutting machine, a slide rail is installed on one side of the bubble bag cutting machine, a movable plate is installed on one side of the bubble bag cutting machine, a support plate is installed on the top of the bubble bag cutting machine, a cutting knife is installed at the bottom of the support plate, a baffle is installed at the bottom of the support plate, and the bubble bag cutting device is used to connect bolts through an arranged connecting plate, and then through an arranged pressing plate for The two ends of the bubble bag to be cut are clamped by bolts to prevent the bubble bag from loosening. When the shearing part performs subsequent bubble bag shearing, it can cut the bubble bag under the support of the pressing plate, thereby achieving a high efficiency effect. Although the cutting knife on the bottom of the support plate slides on the workbench through the movable plate, the two sets of pressing plates are fixed on the two ends of the workbench through the corresponding fixed plates. When the support plate moves to the place to be cut, the two sets of pressing plates cannot be adjusted, resulting in the two sets of pressing plates being unable to effectively press the bubble bag at the place to be cut, affecting the subsequent cutting effect. On this basis, a cutting device for bubble bags is proposed. Utility Model Content

Since the technical content in this field is vast and too complicated, the above-mentioned content of this application does not necessarily constitute the prior art. In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as there is no conflict between each other. Example 1

[0028] Referring to 1-3, this embodiment provides a cutting device for bubble bags, including a workbench 1, brackets 2 are slidably provided on the outside of both sides of the workbench 1, a cutting assembly 3 is provided on the brackets 2, brackets 5 are respectively provided on the top surfaces of both ends of the brackets 2 and are driven by a driving assembly 4 to move, a pressing assembly 6 is provided on the brackets 5, and the driving assembly 4 includes a motor 41 arranged on the outer wall of one side of the workbench 1, a screw 42 extending to the inner wall of the workbench 1 is provided at the output end of the motor 41, a screw block 43 is threadedly connected to the screw 42, and the screw block 43 is limitedly slidably arranged in the workbench 1;

[0029] A sliding rod 44 is provided on the inner wall of the other side of the workbench 1 , and a sliding block 45 is slidably provided on the sliding rod 44 . The sliding block 45 and the top surface of the corresponding screw block 43 jointly support the bracket 2 5 .

[0030] Bracket 1 2 drives the cutting assembly 3 to slide on the outside of the workbench 1 and move to the area to be cut. At this time, the driving motor 41 rotates forward or reversely to drive the screw 42 to rotate accordingly, so that the screw block 43 moves along the direction of the screw 42, and cooperates with the slider 45 to move on the slide rod 44 to achieve the position adjustment of bracket 2 5. Since the two groups of brackets 2 5 are respectively driven by two groups of driving assemblies 4, when the two groups of brackets 2 5 are moved to a suitable (close) position with bracket 1 2, the bubble bag is clamped by the clamping assembly 6, and finally the cutting assembly 3 cuts the clamped bubble bag, and the cutting effect is good. The cutting assembly 3 can be implemented using the existing technology, which will not be repeated here.

[0031] In a preferred embodiment, mounting grooves 7 are provided on the outside of both sides of the workbench 1, and built-in sliders 21 are provided on the bottom surfaces of both ends of the bracket 2. Two groups of sliders 21 are correspondingly slidably arranged in the corresponding mounting grooves 7, and the bracket 2 is slidably arranged on the outside of the workbench 1 through the sliders 21.

[0032] In a preferred embodiment, both ends of the installation groove 7 are provided with limit blocks 8 for limiting the bracket 2 , and the limit blocks 8 effectively prevent the bracket 2 from sliding out of the installation groove 7 .

[0033] In a preferred embodiment, the clamping assembly 6 includes a cylinder 61 arranged on the surface of the bracket 2 5, and the output end of the cylinder 61 is provided with a piston rod 62 passing through the bracket 2 5, and the bottom surface of the piston rod 62 is provided with a trapezoidal pressure block 63. The cylinder 61 pushes the piston rod 62 to descend, driving the trapezoidal pressure block 63 to clamp the bubble bag placed on the surface of the workbench 1 to facilitate cutting.

[0034] In a preferred embodiment, two groups of telescopic slide rods 64 are provided between the bracket 2 5 and the trapezoidal pressure block 63. The two groups of telescopic slide rods 64 are arranged at both ends of the piston rod 62. The telescopic slide rods 64 perform corresponding lifting and lowering movements with the lifting and lowering of the piston rod 62 to assist in supporting the trapezoidal pressure block 63. Example 2

[0035] Reference Figure 4-5 Compared with Example 1, this embodiment also includes: an auxiliary clamping assembly 9 is provided on the inner wall of the middle part of the workbench 1, and the auxiliary clamping assembly 9 includes an air pump 91 arranged in the workbench 1, and the air pump 91 is connected to a pressure dividing box 93 through a conduit 92, and the pressure dividing box 93 is connected to an air hole 94 arranged on the surface of the workbench 1.

[0036] When the conveyor belt conveys the bubble bag to the workbench 1, the bracket 1 drives the cutting assembly 3 to slide outside the workbench 1 and move to the area to be cut. At this time, the driving motor 41 rotates forward or reversely to drive the screw 42 to rotate accordingly, so that the screw block 43 moves along the direction of the screw 42, and cooperates with the slider 45 to move on the slide bar 44 to achieve the position adjustment of the bracket 2 5. Since the two groups of brackets 2 5 are driven by the two groups of driving assemblies 4 respectively, it is convenient to move the two groups of brackets 2 5 to a suitable (close) position with the bracket 1 2;

[0037] At this time, the cylinder 61 pushes the piston rod 62 to drive the trapezoidal pressing block 63 to compress the bubble bag transported to the surface of the workbench 1, and the vacuum pump 91 is started by the motor. After the vacuum pump 91 is turned on, it evacuates air. At this time, the air pressure inside the conduit 92 and the pressure dividing box 93 will be reduced. Under the action of the external atmospheric pressure, the external air passes through the air hole 94 to press the bubble bag attached to the workbench 1 tightly against the upper surface of the workbench. Under the pressing action of the pressing component 6 and the auxiliary pressing component 9, the cutting component 3 cuts the compressed bubble bag, and the cut bubble bag is transported through the conveyor belt;

[0038] The auxiliary pressing assembly 9 can prevent the bubble bag from wrinkling due to external impact, and can also keep the wrinkled bubble bag flat during cutting, thereby making the cutting more neat and accurate.

[0039] The above-described embodiments only express a certain implementation method of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the patent of the utility model shall be based on the attached claims.
