Technical Field

[0001] The present invention relates to the technical field of packaging equipment, in particular to an automatic heat-sealing packaging machine. Background Art

[0002] Currently, most packaging boxes are covered with a film to seal the outside of the box. This protects the box, serves as a sign of unopened packaging, and also acts as a moisture barrier. To prevent interference with the conveyor mechanism during heat sealing, the heat seal mechanism is often located between two conveyors or at the end of a conveyor mechanism, and is manually operated by an operator. This packaging method leaves much to be desired. Summary of the Invention

[0003] Therefore, the main technical problem solved by the present invention is to provide a packaging machine that can automatically heat-seal during the transportation process.

[0004] To achieve the above-mentioned purpose, the technical solution of the embodiment of the present invention is implemented as follows:

[0005] An automatic heat-sealing packaging machine comprises a workbench, a first conveying platform, a second conveying platform and a heat-sealing mechanism arranged on the workbench; the first conveying platform and the second conveying platform are connected end to end, and the first conveying platform is used to convey the product covered with packaging film to the second conveying platform; a recessed portion is formed on the second conveying platform, and the heat-sealing mechanism comprises a frame, a lower heat-sealing member, a linear telescopic assembly connected to the frame, and an upper heat-sealing member connected to the linear telescopic assembly, the frame is connected to the workbench, the lower heat-sealing member is fixedly connected to the workbench and is located in the recessed portion, and the linear telescopic assembly drives the upper heat-sealing member to move closer to or away from the lower heat-sealing member in the vertical direction to heat-seal the packaging film located on the second conveying platform.

[0006] Preferably, the second transmission platform includes a first drive motor, a belt and multiple conveying rollers, the belt passes around each of the conveying rollers in turn, and the first drive motor is connected to one of the conveying rollers; 4 conveying rollers are provided at the recessed portion to guide the belt to sink; at least 2 conveying rollers are provided at the end of the second transmission platform to stretch the belt.

[0007] Preferably, the frame is slidably engaged with the workbench, and the sliding direction of the frame is parallel to the length direction of the second transmission platform; the heat sealing mechanism also includes a second drive motor, an eccentric guide rail and a connecting rod arranged below the second transmission platform, and the second drive motor is transmission-connected to the eccentric guide rail to drive the eccentric guide rail to rotate eccentrically; one end of the connecting rod is slidably engaged with the eccentric guide rail, and the other end of the connecting rod is hinged to the frame.

[0008] Preferably, the connecting rod is an elastic damping rod; a slide rail extending along the length direction of the second transfer table is arranged on the workbench, and the machine frame is slidably matched with the slide rail.

[0009] Preferably, a guiding mechanism is further arranged on the workbench. The guiding mechanism includes a base, a mounting seat, and a pair of conveyor belt mechanisms arranged on the mounting seat; the base is arranged on the side of the first transfer table, the mounting seat is slidably matched with the base in the vertical direction, and a height adjusting screw is arranged on the base, and the height adjusting screw is in screw fit with the mounting seat to adjust the height of the mounting seat.

[0010] Preferably, the length direction of the conveyor belt mechanism is parallel to the length direction of the first transfer table, and the pair of conveyor belt mechanisms are close to each other to form a transfer channel for clamping the packaging film.

[0023] Please refer to the attached Figure 1 to the attached Figure 4, this application provides an automatic heat-sealing packaging machine, which includes a workbench 100, a first transfer table 200, a second transfer table 300, and a heat-sealing mechanism 400 arranged on the workbench 100; the first transfer table 200 and the second transfer table 300 are connected end to end, and the first transfer table 200 is used to convey the product covered with the packaging film to the second transfer table; a recess 310 is formed on the second transfer table 300, and the heat-sealing mechanism 400 is arranged corresponding to the recess 310. When the product covered with the packaging film passes through the recess 310, the edge of the packaging film is heat-sealed by the heat-sealing mechanism 400. Among them, the heat-sealing mechanism 400 includes a frame 410, a lower heat-sealing member 420, a linear telescopic assembly 430 connected to the frame 410, and an upper heat-sealing member 440 connected to the linear telescopic assembly 430. The frame 410 is connected to the workbench 100, the lower heat-sealing member 420 is fixedly connected to the workbench 100 and is located in the recess 310, and the linear telescopic assembly 430 drives the upper heat-sealing member 440 to approach or move away from the lower heat-sealing member 420 in the vertical direction to heat-seal the packaging film located on the second transfer table 300. Among them, the linear telescopic assembly 430 can be a cylinder, a hydraulic cylinder or an electric push rod. When the product covered with the packaging film is sent to the recess 310, the linear telescopic assembly 430 drives the upper heat-sealing member 440 to descend and contact the lower heat-sealing member 420 to heat-seal the packaging film. After heat-sealing, the linear telescopic assembly 430 drives the upper heat-sealing member 440 to rise, and the second transfer table 300 drives the next product to be heat-sealed to move to the recess 310.

[0024] In the above technical solution of this application, the automatic heat-sealing packaging machine includes a workbench 100, a first transfer table 200, a second transfer table 300, and a heat-sealing mechanism 400 arranged on the workbench 100; a recess 310 is formed on the second transfer table 300, so that the heat-sealing mechanism 400 can be arranged corresponding to the recess 310, and when the product covered with the packaging film passes through the recess 310, the packaging film is heat-sealed. Since the lower heat-sealing member 420 of the heat-sealing mechanism 400 is located in the recess 310, the transfer surface of the second transfer table 300 remains relatively flat, which does not affect the smooth transportation of the product. After the heat-sealing mechanism 400 and the second transfer table 300 are combined through this structure, not only will there be no interference, but also the overall volume of the automatic heat-sealing packaging machine can be reduced, the floor area can be reduced, and at the same time, automatic heat-sealing during the transfer process can be realized, improving the processing efficiency.

[0025] As a preferred embodiment of the present invention, the second transfer table 300 includes a first driving motor 320, a belt 330, and a plurality of conveyor rollers 340. The belt 330 bypasses each conveyor roller 340 in sequence. The first driving motor 320 is drivingly connected to one of the conveyor rollers 340, thereby driving the belt 330 to move for transporting products. In the embodiment shown in the drawings, there are 4 conveyor rollers 340 provided at the recessed portion 310 for guiding the belt 330 to sink. Under the limitation of the 4 conveyor rollers 340, the recessed portion 310 presents a trapezoidal recess for the lower heat-sealing member 420 to be inserted. At least 2 conveyor rollers 340 are provided at the end of the second transfer table 300 to stretch the belt 330. In this embodiment, through the guidance of each conveyor roller 340, the special-shaped structure of the belt 330 is realized only by the drive of one motor. Combined with the heat-sealing mechanism 400, automatic heat-sealing is realized during the transfer process, improving the processing efficiency.

[0026] As a preferred embodiment of the present invention, the frame 410 is slidably engaged with the workbench 100, and the sliding direction of the frame 410 is parallel to the length direction of the second transfer table 300; the heat-sealing mechanism 400 further includes a second driving motor 450, an eccentric guide rail 460, and a connecting rod 470 provided below the second transfer table 300. The second driving motor 450 is drivingly connected to the eccentric guide rail 460 to drive the eccentric guide rail 460 to perform eccentric rotation; one end of the connecting rod 470 is slidably engaged with the eccentric guide rail 460, and the other end of the connecting rod 470 is hinged to the frame 410, so that the second driving motor 450, the eccentric guide rail 460, the connecting rod 470, and the frame 410 together form a crank-rocker mechanism. Driven by the second driving motor 450, the heat-sealing mechanism 400 can perform a small linear motion in a direction parallel to the second transfer table 300. Performing a small linear motion during the heat-sealing process can prevent the heat-sealing member from adhering to the packaging film and reduce the bubbles at the heat-sealing location.

[0027] Furthermore, the connecting rod 470 can be an elastic damping rod to reduce the impact force on the heat-sealing mechanism 400; a slide rail 110 extending in the length direction of the second transfer table 300 is provided on the workbench 100, and the frame 410 is slidably engaged with the slide rail 110 to improve the smoothness and accuracy of the movement of the frame 410.

[0028] As an alternative embodiment of the present invention, the automatic heat-sealing packaging machine further includes a guiding mechanism 500 disposed on the workbench 100. The guiding mechanism 500 includes a base 510, a mounting seat 520, and a pair of conveyor belt mechanisms 530 disposed on the mounting seat 520. The base 510 is disposed on the side of the first transfer table 200. The mounting seat 520 is slidably engaged with the base 510 in the vertical direction. A height-adjusting screw 540 is disposed on the base 510. The height-adjusting screw 540 is in screw engagement with the mounting seat 520 to adjust the height of the mounting seat 520. By means of the height-adjusting screw 540, the mounting seat 520 and the conveyor belt mechanisms 530 can be adjusted to a suitable height. A pair of conveyor belt mechanisms 530 can clamp the sides of the packaging film and guide the product to be conveyed towards the recess 310 in an accurate posture. Preferably, the length direction of the conveyor belt mechanisms 530 is parallel to the length direction of the first transfer table 200. A pair of conveyor belt mechanisms 530 are close to each other to form a transfer channel 531 for clamping the packaging film. A pair of conveyor belt mechanisms 530 are respectively located on the upper and lower sides of the packaging film to clamp the sides of the packaging film.

[0029] Please refer to the attached Figure 5 As an alternative embodiment of the present invention, the automatic heat-sealing packaging machine may further include a film-feeding mechanism 600, a third transfer table 700, and a film-folding member 800. The third transfer table 700, the first transfer table 200, and the second transfer table 300 are connected end to end in sequence. The film-feeding mechanism 600 is located on the side of the first transfer table 200 and is used to release the packaging film. The film-folding member 800 is located above the first transfer table 200 and is used to fold the packaging film. The film-feeding mechanism 600 and the film-folding member 800 are prior arts and will not be described in detail herein. After the packaging film released by the film-feeding mechanism 600 is folded by the film-folding member 800, it can smoothly cover the packaging box delivered by the third transfer table 700. Preferably, the film-folding member 800 may be triangular and is connected to the workbench 100 through a lifting bracket 120. The lifting bracket 120 may be driven by a ball screw.
