Description

Technical Field

[0001] The utility model relates to the technical field of punching, in particular to a packaging bag pressing and punching device. Background Art

[0002] Different types of packaging bags have different requirements during the production process. Some packaging bags do not need to be punched after production, and these packaging bags are generally used for vacuum packaging; while other packaging bags need to be punched so that the air inside the bag can be discharged when the packaging bag is used. This difference mainly depends on the material, structure and final use scenario of the packaging bag.

[0003] However, in order to meet the exhaust requirements, packaging bags of different sizes or types need to be punched with exhaust holes of different apertures. The problem is that a packaging bag punching device can generally only punch exhaust holes of one aperture, which undoubtedly limits the scope of application of the punching device. Utility Model Content

[0004] In order to solve the deficiencies of the prior art, the utility model provides a packaging bag pressing and punching device, which can punch exhaust holes with different apertures according to the punching requirements.

[0005] In order to achieve the purpose of this utility model, the following scheme is proposed:

[0006] A packaging bag pressing and punching device comprises a supporting frame, a lifting component, a first rotating disk, and a plurality of punching components.

[0007] The support frame includes a top plate, a movable plate, and a pressing plate from top to bottom. A column is arranged at the bottom of each end of the top plate. The ends of the movable plate and the pressing plate are slidably matched with the columns. Two guide rods are arranged on the top of the pressing plate. The guide rods penetrate the movable plate upward. A first spring is arranged on the outer periphery of the guide rods. The two ends of the first spring are respectively connected to the movable plate and the pressing plate. The table below the pressing plate is used for laying packaging bags.

[0008] The lifting assembly is arranged on the top plate, and its bottom is connected to the moving plate;

[0009] A through hole is provided on the pressure plate, and a first turntable is rotatably arranged on the top of the pressure plate. Multiple punching assemblies are evenly arranged on the first turntable. When the first turntable is rotated according to the gear position, one of the punching assemblies is moved to directly above the through hole. When the punching assembly moves downward and passes through the through hole, it is used to punch holes in the packaging bag.

[0010] Furthermore, it also includes a second turntable, which is rotatably arranged on the top of the pressure plate. The second turntable is provided with a plurality of limit holes with different inner diameters. When the second turntable is rotated according to the gear position, one of the limit holes is aligned with the through hole.

[0011] Furthermore, the inner diameter of the through hole is larger than the inner diameters of all the limiting holes.

[0012] Furthermore, the inner diameter of the limiting hole corresponds one to one with the size of the corresponding punching component.

[0013] Furthermore, a plurality of vertical rods are provided on the top of the first turntable, two vertical rods form a group, and the two vertical rods in a group penetrate the regulating plate upward, and a second spring is provided on the outer periphery of the vertical rod, and the two ends of the second spring are respectively connected to the regulating plate and the first turntable, and the punching assembly is arranged at the bottom of the corresponding regulating plate. When one of the punching assemblies moves to directly above the through hole, the punching assembly is located under the movable plate, and the movable plate is used to move the punching assembly downward and pass through the through hole.

[0014] Furthermore, the support frame is mounted on the conveying platform.

[0015] Furthermore, an inverted L-shaped plate is arranged at each end of the pressure plate, the longitudinal section of the inverted L-shaped plate is connected to the pressure plate, the transverse section of the inverted L-shaped plate is slidably matched with the corresponding column, and the guide rod is arranged at the top of the transverse section of the inverted L-shaped plate.

[0016] The beneficial effect of the utility model is that: a punching assembly is selected in advance, the punching assembly is rotated to the top of the through hole, and then the lifting assembly is used to move the movable plate and the pressing plate downward. When the pressing plate presses the packaging bag, the punching assembly continues to move downward and passes through the through hole, thereby punching holes in the packaging bag. The utility model is provided with a plurality of punching assemblies of different sizes. According to the punching requirements, one of the punching assemblies can be selected, and the operation is also very simple, and only the first rotating disk needs to be rotated.

[0021] like Figure 1 As shown, this embodiment provides a packaging bag pressing and punching device, including a support frame 1, a lifting component 2, a first rotating disk 51, and four punching components 4.

[0022] Specifically, Figure 1 , Figure 2As shown, the support frame 1 includes a top plate 11, a movable plate 12 and a pressure plate 13 from top to bottom, and a column 14 is respectively arranged at the bottom of both ends of the top plate 11, and the ends of the movable plate 12 and the pressure plate 13 are slidably matched with the corresponding columns 14, and two guide rods 131 are arranged on the top of the pressure plate 13, and the guide rods 131 penetrate the movable plate 12 upward, and a first spring 132 is arranged on the outer periphery of the guide rods 131, and the two ends of the first spring 132 are respectively connected to the movable plate 12 and the pressure plate 13. In order to prevent the guide rods 131 from detaching from the movable plate 12, a convex plate with a diameter larger than the guide rod 131 is arranged on the top of the guide rod 131, and the table surface under the pressure plate 13 is used for laying packaging bags, and the lifting component 2 is arranged on the top plate 11, and the bottom of the lifting component 2 is connected to the movable plate 12 for controlling the height of the movable plate 12. There are many ways to implement the lifting component 2, such as using a lifting rod driven by a cylinder, an oil cylinder or a hydraulic pressure, which will not be elaborated here.

[0023] In this embodiment, the support frame 1 is set on the conveying platform 6, and an inverted L-shaped plate 134 is set at each end of the pressure plate 13. The longitudinal section of the inverted L-shaped plate 134 is connected to the pressure plate 13, and the transverse section of the inverted L-shaped plate 134 is slidably matched with the corresponding column 14. The guide rod 131 is set at the top of the transverse section of the inverted L-shaped plate 134, and the two ends of the first spring 132 are respectively connected to the movable plate 12 and the transverse section of the inverted L-shaped plate 134.

[0024] When in use, the conveyor platform 6 is used to convey the packaging bags in sequence and convey the packaging bags to the bottom of the pressing plate 13; the lifting component 2 is used to move the movable plate 12 downward, and the pressing plate 13 also moves downward with the movable plate 12. When the pressing plate 13 contacts the packaging bag, the lifting component 2 continues to move the movable plate 12 downward, and the pressing plate 13 will no longer move with it. The first spring 132 has a buffering effect. The function of the pressing plate 13 is to press the packaging bag to facilitate punching of the packaging bag.

[0025] Specifically, Figure 1 , Figure 4 As shown, a through hole 133 is provided on the pressing plate 13, and a first turntable 51 is rotatably provided on the top of the pressing plate 13. Four punching components 4 are evenly provided on the first turntable 51. The punching components 4 are conventional components, and their structures are not described in detail here. The four punching components 4 are of different sizes and are used to punch exhaust holes of different apertures for the packaging bag. Four gears are provided on the first turntable 51. The gears are prior art, and their structures and principles are not described in detail here. The first turntable 51 rotates 90° each time to move one of the punching components 4 to the top of the through hole 133. When the punching component 4 moves downward and passes through the through hole 133, it is used to punch holes in the packaging bag.

[0026] The method for realizing the downward movement of the punching assembly 4 is as follows: Figure 1 , Figure 2 , Figure 4As shown, eight vertical rods 511 are provided on the top of the first turntable 51, and two vertical rods 511 form a group. The two vertical rods 511 in a group penetrate the same regulating plate 512 upward, and a second spring 513 is provided on the outer periphery of the vertical rod 511. The two ends of the second spring 513 are respectively connected to the regulating plate 512 and the first turntable 51. The punching assembly 4 is arranged at the bottom of the corresponding regulating plate 512. When one of the punching assemblies 4 moves to just above the through hole 133, the punching assembly 4 is just located below the movable plate 12. Then, when the movable plate 12 moves downward, the punching assembly 4 can be moved downward and pass through the through hole 133.

[0027] The punching method is as follows: when the pressing plate 13 moves downward and contacts the packaging bag, the lifting component 2 continues to move the movable plate 12 downward, and the pressing plate 13 will no longer move therewith. During the downward movement of the movable plate 12, it first contacts the regulating plate 512, and then presses down the regulating plate 512, thereby prompting the punching component 4 to move downward and pass through the through hole 133. The punching component 4 completes the punching of the packaging bag under the pressing plate 13; the lifting component 2 moves the movable plate 12 upward, and after the regulating plate 512 loses the restriction of the movable plate 12, it resets upward under the action of the second spring 513, thereby disengaging from the through hole 133.

[0028] In order to further improve the accuracy of punching, the device of this embodiment further includes a second rotating disk 52. Figure 1 , Figure 3 , Figure 4 As shown, the second turntable 52 is rotatably arranged on the top of the pressure plate 13, and four limiting holes 521 with different inner diameters are arranged on the second turntable 52. The second turntable 52 is also provided with four gears. When the second turntable 52 is rotated according to the gear, it is used to align one of the limiting holes 521 with the through hole 133. The inner diameter of each limiting hole 521 corresponds to the size of the corresponding punching component 4 one by one. The inner diameter of the through hole 133 is larger than the inner diameter of all the limiting holes 521. When punching, the punching component 4 first passes through the corresponding limiting hole 521 and then passes through the through hole 133.

[0029] The above embodiments are only used to illustrate the technical ideas and features of the utility model, and are not intended to be the only or limit the utility model. Those skilled in the art should understand that various changes or equivalent replacements made to the utility model without departing from the scope of the utility model are within the scope of protection of the utility model.
