Description

Technical Field

[0001] This utility model relates to the field of plastic bag production technology, specifically to a bottom sealing and punching device for plastic bag production. Background Technology

[0002] Plastic bags are bags made of plastic and are widely used in shopping, packaging, and other fields. They are widely used because they are lightweight, durable, and waterproof. However, the use of plastic bags has also brought some environmental problems.

[0003] According to a public disclosure of a punching device for a plastic bag production line (publication number: CN216001631U): it includes a base, an unwinding roller, and a drive roller. A support plate is provided on one side of the upper part of the base. The unwinding roller is installed on one side wall of the support plate. An electric telescopic rod is fixed to one side of the support plate. A tightening roller is installed on one side wall of the electric telescopic rod. A second support plate is fixed to one side of the electric telescopic rod. The drive roller is installed on one side wall of the second support plate.

[0004] In the aforementioned application, the cooperation between the unwinding roller and the drive roller assembly makes it difficult to press and fix the plastic strip before the bottom sealing punching of the plastic bag. This may cause the plastic strip to shift during punching, resulting in poor punching effect and affecting the processing requirements of the plastic strip. Therefore, we propose a bottom sealing punching device for plastic bag production. Utility Model Content

[0026] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0027] like Figures 1-5 As shown, it illustrates a bottom sealing and punching device for plastic bag production in one embodiment of the present invention, including a workbench 1, a support frame 2 fixedly connected to the top of the workbench 1, a transport wheel 3 rotatably connected inside the workbench 1, and a bottom sealing and punching device 4 disposed inside the support frame 2. The bottom sealing punching device 4 includes a motor 41, the side of which is fixedly connected to the inner wall of the support frame 2. The output shaft of the motor 41 is fixedly connected to a rotating shaft 42, and a gear 43 is fixedly connected to the circumferential surface of the rotating shaft 42. A rack 44 is slidably connected to the inner wall of the support frame 2. A fixing plate 45 is fixedly connected to the bottom of the rack 44. A telescopic rod 46 is fixedly connected to the bottom of the fixing plate 45. A bottom sealing plate 47 is fixedly connected to the telescopic end of the telescopic rod 46. A punching blade 48 is fixedly connected to the side of the fixing plate 45. A pressing table 49 is fixedly connected to the bottom of the worktable 1. This design is beneficial for fixing plastic products and preventing them from slipping.

[0028] In some examples, a connecting rod 410 is fixedly connected to the side of the fixed plate 45. There are two fixed plates 45, bottom plates 47 and pressing tables 49, which are symmetrical to each other along the vertical central axis of the worktable 1. The end of the connecting rod 410 away from the fixed plate 45 is fixedly connected to the side of the other fixed plate 45. The purpose is to make the fixation on both sides more stable.

[0029] The bottom plate 47 is equipped with a heater 411, and the support frame 2 is equipped with an electric conveyor wheel 412, the purpose of which is to enable the plastic bag to be transported automatically.

[0030] A spring 413 is fixedly connected to the circumferential surface of the telescopic rod 46. The end of the spring 413 away from the telescopic rod 46 is fixedly connected to the top of the bottom plate 47. The purpose of this is to allow the spring 413 to drive the telescopic rod 46 to extend and retract.

[0031] The bottom of the bottom plate 47 is located directly above the pressing table 49. The gear 43 and the rack 44 mesh with each other to ensure that the bottom plate 47 can be pressed against the pressing table 49.

[0032] For example, such as Figures 1-5As shown, when workers need to perform bottom sealing and punching on plastic bags, the plastic bags are transported to the other side via electric conveyor wheels 412. At this time, motor 41 is started, and the output shaft of motor 41 drives rotating shaft 42 to rotate. During the rotation of rotating shaft 42, gear 43 is driven to rotate. During the rotation of gear 43, it meshes with rack 44, thereby driving rack 44 to move. During the movement of rack 44, fixed plate 45 is driven to move. During the movement of fixed plate 45, telescopic rod 46 and punching blade 48 are driven to move. Through connecting rod 410, fixed plate 45, telescopic rod 46 and bottom sealing plate 47 on the other side are driven to press downward, thereby achieving the effect of bottom sealing and punching on plastic bags, improving work efficiency and reducing manual labor.

[0033] like Figures 1-5 As shown, this invention illustrates a bottom-sealing and punching device for producing plastic bags according to another embodiment of the present invention. The device includes: a heat dissipation device 5 on the top of a workbench 1, comprising a bevel gear 51 fixedly connected to the circumferential surface of a rotating shaft 42; a rotating shaft 52 rotatably connected to the inner top of a support frame 2, a bevel gear 53 fixedly connected to the circumferential surface of the rotating shaft 52, a belt shaft 54 ​​fixedly connected to the circumferential surface of the rotating shaft 52, a belt 55 disposed on the circumferential surface of the belt shaft 54; a rotating shaft 56 rotatably connected to the inner top of the support frame 2, a belt shaft 57 fixedly connected to the circumferential surface of the rotating shaft 56; the belt shaft 54 ​​is rotatably connected to the belt shaft 57 via the belt 55; a fan blade 58 fixedly connected to the circumferential surface of the rotating shaft 52; and a fan blade 59 fixedly connected to the circumferential surface of the rotating shaft 56. This design facilitates heat dissipation of the processed plastic bags and prevents them from sticking together. In some examples, a slide plate 510 is fixedly connected to the side of the workbench 1, and a collection bin 511 is provided at the bottom of the slide plate 510, the purpose of which is to better collect the processed plastic bags and reduce manual labor.

[0034] The top of the workbench 1 is fixedly connected to a limiting plate 512, and the top of the slide plate 510 is fixedly connected to a guard plate 513. This design helps to prevent the plastic bag from slipping sideways.

[0035] There are several fan blades 58 and 59, which are arranged in a circular array along the circumference of the rotating shaft 2 52 and the rotating shaft 3 56 respectively. Fan blades 58 and 59 are located directly above the worktable 1. This design helps to improve heat dissipation and prevent the processed plastic bags from sticking together.

[0036] The first bevel gear 51 and the second bevel gear 53 mesh with each other. There are two slide plates 510 and two collection bins 511, which are symmetrical about each other along the vertical central axis of the worktable 1. This design is conducive to the rotation of the first bevel gear 51 to drive the second bevel gear 53 to rotate.

[0037] For example, such as Figures 1-5 As shown, during the rotation of shaft 42, bevel gear 51 rotates. During the rotation of bevel gear 51, it meshes with bevel gear 53, causing bevel gear 53 to rotate. During the rotation of bevel gear 53, shaft 52 rotates. During the rotation of shaft 52, belt shaft 54 ​​rotates. During the rotation of belt shaft 54, belt shaft 57 rotates via belt. During the rotation of belt shaft 57, shaft 56 rotates. During the rotation of shafts 52 and 56, fan blades 58 and 59 rotate, thereby achieving the effect of heat dissipation for the plastic bag after the bottom sealing and punching process, which can effectively prevent the plastic bag from sticking together.
