Description

Technical Field

[0001] This utility model relates to the field of bag making machine technology, and more specifically, to a heat-sealing temperature adaptive bag making machine. Background Technology

[0002] A bag making machine is a machine that produces various plastic or other material packaging bags. The heat-sealing temperature adaptive bag making machine combines intelligent technology and heat sealing technology. It can automatically adjust the heat sealing temperature according to different materials and sealing requirements. It performs heat sealing through a vertically lifting hot cutter. Generally, a temperature sensor is set at the hot cutter to detect the temperature.

[0003] The heat-sealing blade of the existing heat-sealing temperature adaptive bag making machine tends to wrinkle the hollow areas of the packaging bag during heat sealing. In order to seal the wrinkled packaging bag tightly, the temperature of the heat-sealing blade needs to be increased. However, after heat sealing, the heat-sealing blade is prone to sticking to the packaging bag due to excessive temperature. In view of this, we propose a heat-sealing temperature adaptive bag making machine. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a heat-sealing temperature adaptive bag making machine to solve the technical problem that the heat-sealing knife of the current heat-sealing temperature adaptive bag making machine is easy to stick to the packaging bag when heat-sealing pleated packaging bags.

[0005] To solve the above technical problems, the present invention provides the following technical solution: a heat-sealing temperature adaptive bag making machine, including a frame, wherein an unwinding assembly, a transfer roller, a transverse heat-sealing assembly, a longitudinal heat-sealing assembly, a material pulling assembly and a cold cutting assembly are sequentially installed in the frame, and a flattening assembly is installed on one side of both the transverse heat-sealing assembly and the longitudinal heat-sealing assembly.

[0006] The paving assembly includes a bidirectional displacement drive unit consisting of a limiting shell, a second servo motor, a bidirectional threaded screw, and a screw sleeve. Two electric telescopic rods are symmetrically installed at the power output end of the bidirectional displacement drive unit, and paving strips are installed at the ends of the electric telescopic rods.

[0007] The paving strip is C-shaped with its openings facing each other, and the bottom edge of the paving strip is chamfered.

[0008] Preferably, a first workbench is provided below the transverse heat sealing assembly and the longitudinal heat sealing assembly, and a second workbench is provided below the cold cutting assembly.

[0009] Preferably, the unwinding assembly includes an unwinding roller, which is rotatably mounted inside the frame, and the power input end of the unwinding roller is connected to the power output end of a first servo motor.

[0010] Preferably, the material pulling assembly includes a pair of material pulling rollers rotatably mounted in the frame, and the power input end of the pair of material pulling rollers is connected to the power output end of the drive assembly.

[0011] Preferably, a bidirectional threaded screw is rotatably installed inside the limiting shell. Both the left-hand threaded end and the right-hand threaded end of the bidirectional threaded screw are threadedly connected to a screw sleeve. An electric telescopic rod is fixedly installed outside the screw sleeve. The power input end of the bidirectional threaded screw is connected to the power output end of a second servo motor.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. The bidirectional displacement drive unit of this utility model, in conjunction with the electric telescopic rod, can drive two flattening strips to move simultaneously to both ends of the packaging bag on the first worktable, smoothing out the packaging bag near the heat sealing component, reducing wrinkles at the packaging bag to be heat sealed, and after smoothing, the packaging bag is pressed by the ends of the flattening strips which are C-shaped and have opposite openings, so that the heat sealing component can be smoothly separated from the packaging bag after heat sealing, with good anti-sticking effect, solving the problem that the heat sealing knife of the current heat sealing temperature adaptive bag making machine is easy to stick to the packaging bag when heat sealing wrinkled packaging bags.

[0014] 2. This utility model also features a C-shaped flattening strip structure with opposite openings. The bottom edge of the flattening strip has a chamfer. When the two C-shaped flattening strips slide towards both ends on the packaging bag, they flatten the wrinkles on the packaging bag. The rounded part of the C-shape ensures smoother sliding. The chamfer protects the packaging bag, making it less likely to be cut by the edges of the flattening strip. This solves the problem that the heat sealing knife of the current heat-sealing temperature adaptive bag making machine easily sticks to the packaging bag when heat sealing wrinkled packaging bags.

[0023] like Figures 1 to 4 As shown, the present invention relates to a heat-sealing temperature adaptive bag making machine, which includes a frame 1. The frame 1 is sequentially equipped with an unwinding assembly 2, a transfer roller 3, a transverse heat-sealing assembly 5, a longitudinal heat-sealing assembly 6, a material pulling assembly 8, and a cold cutting assembly 9. A flattening assembly 4 is installed on one side of both the transverse heat-sealing assembly 5 and the longitudinal heat-sealing assembly 6.

[0024] The paving assembly 4 includes a bidirectional displacement drive unit consisting of a limiting shell 403, a second servo motor 404, a bidirectional threaded screw 405, and a screw sleeve 406. Two electric telescopic rods 402 are symmetrically installed at the power output end of the bidirectional displacement drive unit, and paving strips 401 are installed at the ends of the electric telescopic rods 402.

[0025] The flattening strip 401 is C-shaped with its openings facing each other. The bottom edge of the flattening strip 401 is chamfered. The bidirectional displacement drive unit of this utility model, together with the electric telescopic rod 402, can drive the two flattening strips 401 to move simultaneously to both ends on the packaging bag on the first workbench 7, smoothing the packaging bag near the heat sealing component, reducing wrinkles on the packaging bag to be heat sealed, and after smoothing, the packaging bag is pressed by the ends of the C-shaped flattening strips 401 with their openings facing each other, so that the heat sealing component can be smoothly removed from the packaging bag after heat sealing, with good anti-sticking effect.

[0026] Furthermore, a first workbench 7 is provided below the transverse heat sealing assembly 5 and the longitudinal heat sealing assembly 6, and a second workbench 10 is provided below the cold cutting assembly 9, to facilitate heat sealing and cold cutting operations.

[0027] Furthermore, the unwinding assembly 2 includes an unwinding roller 201, which is rotatably mounted inside the frame 1. The power input end of the unwinding roller 201 is connected to the power output end of the first servo motor 202, which facilitates the unwinding of unsealable packaging bag rolls.

[0028] Furthermore, the material pulling assembly 8 includes a material pulling roller 801 rotatably mounted in the frame 1. The power input end of the material pulling roller 801 is connected to the power output end of the drive assembly 802 to facilitate material pulling.

[0029] Furthermore, a bidirectional threaded screw 405 is rotatably installed inside the limiting shell 403. Both the left-hand threaded end and the right-hand threaded end of the bidirectional threaded screw 405 are threadedly connected to a screw sleeve 406. An electric telescopic rod 402 is fixedly installed outside the screw sleeve 406. The power input end of the bidirectional threaded screw 405 is connected to the power output end of the second servo motor 404, which facilitates the translation of the paving strip 401.

[0030] Working Principle: This embodiment provides a heat-sealing temperature adaptive bag making machine. In use, the bidirectional displacement drive unit of this invention, in conjunction with the electric telescopic rod 402, can simultaneously move two flattening strips 401 across the packaging bag on the first worktable 7, smoothing the packaging bag near the heat-sealing assembly, reducing wrinkles at the packaging bag to be heat-sealed. After smoothing, the ends of the flattening strips 401, which are C-shaped with opposite openings, press the packaging bag, allowing the heat-sealing assembly to smoothly detach from the packaging bag after heat sealing, resulting in good anti-sticking effect. Before heat cutting, external power supply is connected. The second servo motor 404 and the electric telescopic rod 402 are turned on via an external switch. After the electric telescopic rod 402 extends, the second servo motor 404 rotates clockwise. After the electric telescopic rod 402 extends, the "C"-shaped flattening strip 401 with its openings facing each other adheres to the packaging bag on the top of the first workbench 7. The second servo motor 404 drives the bidirectional threaded screw 405 to rotate clockwise. The screw sleeves 406 at the left-hand and right-hand threaded ends of the bidirectional threaded screw 405 rotate synchronously to both ends. The screw is limited by the limiting shell 403, and the screw sleeves 406 drive the rotation. Simultaneously, the two sets of electric telescopic rods 402 and the flattening strip 401 slide towards the edges of the packaging bag, flattening it. The bottom edge of the flattening strip 401 has a chamfer, and the "C"-shaped arc ensures smoother sliding. The chamfer protects the packaging bag, making it less likely to be cut by the edges of the flattening strip 401. After sliding to the edge, the end of the "C"-shaped flattening strip 401 presses down on the packaging bag, and is then heat-sealed by the transverse heat-sealing component 5 and the longitudinal heat-sealing component 6 respectively. Because the end of the "C"-shaped flattening strip 401 presses down on the packaging bag, the transverse heat-sealing component 5 and the longitudinal heat-sealing component 6 can seal the bag. After being heat-sealed by heat sealing assembly 5 and longitudinal heat sealing assembly 6, it quickly detaches from the packaging bag with good anti-sticking effect. Both transverse heat sealing assembly 5 and longitudinal heat sealing assembly 6 include lifting components such as hydraulic rods and heat sealing blades at the ends of hydraulic rods. Cold cutting assembly 9 includes lifting components such as hydraulic rods and cold cutting blades at the ends of hydraulic rods. (Transverse heat sealing assembly 5, longitudinal heat sealing assembly 6, cold cutting assembly 9, first servo motor 202, electric telescopic rod 402, second servo motor 404, and drive assembly 802 are all existing products on the market and are all connected to external power supply and external switch).
