Description

Technical Field

[0001] The utility model relates to the technical field of packaging machinery, in particular to a heat-sealing device for plastic and paper-plastic-based packaging materials. Background Technique

[0002] When plastic and paper-plastic-based packaging materials are used for packaging, splicing between plastic and paper-plastic-based packaging materials is often required. When splicing existing plastic and paper-plastic-based packaging materials, the two joints are first cut and aligned, then the two joints are overlapped and placed, and then a heating plate is used to heat and press the two overlapped joints to complete the splicing.

[0003] When performing heat-sealing treatment on plastic and paper-plastic-based packaging materials, generally, the joints are first pressed by a pressure roller, and then the heat-sealing treatment at the joints is realized by a heating plate. The two operations are carried out separately, with poor coherence, long time, and the need to use pressing and heat-sealing components respectively, occupying a large space and having a high cost. Moreover, when the device is used, double-sided heat-sealing of plastic and paper-plastic-based packaging materials cannot be achieved, and the heat-sealing treatment effect is not ideal, so improvement is needed. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a heat-sealing device for plastic and paper-plastic-based packaging materials. By setting a pressure roller, a sliding block, a rack, a rotary driving component, a heat-sealing mechanism and a track plate, when the pressure roller presses the joints, the rotary driving component drives the upper and lower two heat-sealing mechanisms to rotate simultaneously, realizing double-sided heat-sealing of plastic and paper-plastic-based packaging materials, and solving the problems of poor heat-sealing effect and poor heat-sealing coherence of the current device.

The rotary driving component includes two groups of support seats fixedly connected to the upper and lower sides of the workbench, and two large gears rotatably connected to the two groups of support seats. The two large gears are meshed with each other, and a small gear is coaxially fixed on one of the large gears;

[0008] Heat-sealing mechanisms, there are two heat-sealing mechanisms, and both heat-sealing mechanisms are composed of a turning frame, a cross plate and an electric heating plate.

[0009] The track plate is fixedly connected to the workbench along the length direction of the workbench, and a sliding block is slidably connected to the track plate. A rack is fixedly connected to the upper surface of the sliding block. The rack is meshed and connected with a corresponding small gear. When the sliding block and the rack slide on the track plate, the rotation of the large gear can be driven through the meshing relationship between the rack and the small gear. The two large gears rotate simultaneously, and then drive the two heat-sealing mechanisms to rotate, realizing the double-sided heat-sealing of plastic and paper-plastic-based packaging materials.

[0010] Further, a pressure roller is rotatably connected between the two sliding blocks.

[0011] Further, a mounting frame is fixedly connected to one side of the workbench, and a cylinder is installed on the mounting frame. A traction frame is fixedly connected to the sliding block, and the output shaft of the cylinder is fixedly connected to the traction frame.

[0013] Further, support legs are fixedly connected to the four corners of the workbench.

[0014] Compared with the prior art, the present utility model provides a heat-sealing device for plastic and paper-plastic-based packaging materials, which has the following beneficial effects:

[0015] In the present utility model, a pressure roller is rotatably connected between the two sliding blocks, and a heat-sealing mechanism is fixedly connected to one side of the large gear.

Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model. Embodiment

[0021] As Figure 1 , Figure 2 and Figure 3 shown, a thermal connection device for plastic and plastic-paper-based packaging materials proposed in an embodiment of the present utility model includes a workbench 1, and further includes: two rotary drive components 7 symmetrically installed on the workbench 1. The rotary drive component 7 includes two groups of support bases 701 fixedly connected to the upper and lower sides of the workbench 1, and two large gears 703 rotatably connected to the two groups of support bases 701. The two large gears 703 are meshed with each other, and a pinion 702 is coaxially fixed on one of the large gears 703; two thermal connection mechanisms 8, each of the two thermal connection mechanisms 8 is composed of a flip frame 801, a cross plate 802, and an electric heating plate 803. Among them, the flip frame 801 is fixedly connected to the corresponding large gear 703, the cross plate 802 is fixedly connected to the end of the flip frame 801, and the electric heating plate 803 is installed on the cross plate 802; a track plate 10 fixedly connected to the workbench 1 along the length direction of the workbench 1, and a sliding block 5 is slidably connected to the track plate 10. A rack 6 is fixedly connected to the upper surface of the sliding block 5, and the rack 6 is meshed with the corresponding pinion 702. When the sliding block 5 and the rack 6 slide on the track plate 10, the rotation of the large gear 703 can be driven through the meshing relationship between the rack 6 and the pinion 702. The two large gears 703 rotate simultaneously, and then drive the two thermal connection mechanisms 8 to rotate, realizing the double-sided thermal connection of plastic and plastic-paper-based packaging materials.

[0022] It should be noted that the workbench 1 is used for the heat-sealing of plastic and plastic-paper-based packaging materials. By installing a rotary drive component 7 on the workbench 1, the rotary drive component 7 can drive the heat-sealing mechanism 8 to rotate, realizing the heat-sealing processing of plastic and plastic-paper-based packaging materials. The rotary drive component 7 is composed of a support base 701, a small gear 702, and a large gear 703. Among them, there are two large gears 703 that mesh with each other. When one of the large gears 703 rotates, the other large gear 703 will also rotate synchronously, realizing the synchronous rotation of the two large gears 703. By coaxially fixing the small gear 702 on one of the large gears 703, the rotation drive of this large gear 703 is realized. The heat-sealing mechanism 8 is composed of a turning frame 801, a cross plate 802, and an electric heating plate 803. Among them, the turning frame 801 is fixedly connected to the corresponding large gear 703. When the sliding block 5 and the rack 6 slide on the track plate 10, the large gear 703 can be driven to rotate through the meshing relationship between the rack 6 and the small gear 702. The two large gears 703 rotate simultaneously, and then drive the turning frame 801 and the cross plate 802 to turn. The two heat-sealing mechanisms 8 rotate simultaneously, and the heat-sealing treatment on both sides of the plastic and plastic-paper-based packaging materials is realized through the electric heating plate 803.

[0023] As Figure 1 shown, in some embodiments, a pressure roller 4 is rotatably connected between the two sliding blocks 5.

[0024] It should be noted that when the sliding block 5 and the rack 6 slide on the track plate 10, the pressure roller 4 can be driven to move. The pressure roller 4 is used to press the joint of the plastic and plastic-paper-based packaging materials. During the pressing process, the heat-sealing mechanism 8 rotates synchronously. When the pressure roller 4 leaves the joint of the plastic and plastic-paper-based packaging materials, the electric heating plate 803 contacts the joint, realizing the heat-sealing treatment of the joint. The pressing and heat-sealing of the joint of the plastic and plastic-paper-based packaging materials are carried out continuously, with compact processing and short time.

[0025] As Figure 1 shown, in some embodiments, an installation frame 12 is fixedly connected to one side of the workbench 1, and a cylinder 13 is installed on the installation frame 12. A traction frame 3 is fixedly connected to the sliding block 5, and the output shaft of the cylinder 13 is fixedly connected to the traction frame 3.

[0026] It should be noted that the setting of the cylinder 13 can realize the driving effect of the traction frame 3, and then realize the driving effect of the movement of the sliding block 5 and the rack 6. It should also be noted that the present invention can also realize the driving of the traction frame 3 by means of an electric push rod. The electric push rod is installed on the installation frame 12, and its end is connected to the traction frame 3 to realize the driving effect of the movement of the sliding block 5 and the rack 6. The usage method and principle of the electric push rod are known prior arts and will not be elaborated.

[0027] As Figure 1As shown, in some embodiments, a groove 2 is provided on the upper surface of the workbench 1 along the length direction of the workbench 1, plastic and paper-plastic based packaging materials are arranged in the groove 2, and a cavity 9 is provided on one side of the workbench 1 running through from top to bottom.

[0028] It should be noted that the groove 2 is used for placing plastic and paper-based packaging materials. When in use, the plastic and paper-based packaging materials are spread flat on the groove 2, and the joint is set on the cavity 9. The cavity 9 plays a role of giving way and is used for the movement of the electric heating plate 803, and contacts with the plastic and paper-based packaging materials to avoid obstruction.

[0029] like Figure 1 As shown, in some embodiments, support legs 11 are fixedly connected to the four corners of the workbench 1 to achieve support for the device.
