Description

Technical Field

[0001] This utility model relates to the field of heat sealing technology for sugar cubes, and more specifically, to a heat sealing structure for a packaging machine. Background Technology

[0002] Currently available chocolate packaging uses paper packaging film, whose main material is paper. After packaging, no sealing is done. Although it looks good, the product has poor barrier properties, shortens the shelf life and affects the taste. The existing heat sealing technology is a flat through-sealing.

[0003] Because the candy was not fully poured into the mold, a groove was formed on the surface of the candy. As a result, when the packaged candy passed through the heat sealing channel, the paper edge at the groove could not be sealed or the sealing effect was poor.

[0004] Therefore, there is an urgent need for a heat-sealing structure for packaging machines to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a heat-sealing structure for a packaging machine to solve the problems mentioned in the background art.

[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0007] A heat-sealing structure for a packaging machine includes a lifting and pressing module, a horizontal pushing module, and a heat-sealing module. The heat-sealing module includes an adjusting plate, which is connected to the horizontal pushing module via a mounting plate. The mounting plate has an elongated hole for adjusting the horizontal height of the adjusting plate. A base plate is fixedly connected to the outer wall of the adjusting plate by screws. The machine also includes:

[0008] A guide assembly includes guide blocks symmetrically and fixedly connected to the top wall of the base plate. A heat insulation plate is slidably connected to the outer wall of the guide block, and a heat sealing plate is fixedly connected to the inner wall of the heat insulation plate. A heat sealing channel is provided between the heat sealing plate, the guide block and the base plate.

[0009] Heating components are located on the outer wall of the heat-sealing plate.

[0010] As a preferred technical solution of this application, the heating component includes protrusions that are uniformly and fixedly connected to the outer wall of the heat-sealing plate. The outer wall of the protrusions is provided with an arc surface. The protrusions contact the concave surface of the candy, thereby achieving the sealing effect.

[0011] As a preferred technical solution of this application, the lifting and pressing module includes a lower top block fixedly connected to the outer wall of the lifting slider and an upper pressing block fixedly connected to the outer wall of the pressing slider. The outer wall of the upper pressing block is slidably connected with symmetrically distributed shafts. The outer wall of the shaft is fixedly connected with a pressure plate. The outer wall of the shaft is sleeved with a compression spring, and the compression spring is fixedly connected to the pressure plate. The end of the compression spring away from the pressure plate is fixedly connected to the upper pressing block.

[0012] As a preferred technical solution of this application, the horizontal push module includes a sugar pusher block fixed to the horizontal push slider by fasteners.

[0013] As a preferred technical solution of this application, the outer wall of the heat insulation board is fixedly connected with a handle.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] In the scheme of this application:

[0016] By using a raised block with a rounded surface, the candy packaging is sealed. This raised block perfectly fits the concave surface of the candy packaging, creating a tight and thorough contact. Under this close contact, the heat generated by the heating element is efficiently and evenly transferred to the sealing area of ​​the candy packaging. This ensures uniform heating at the sealing point, achieving an ideal sealing effect, guaranteeing the candy packaging's airtightness, effectively extending the candy's shelf life, and maintaining its quality from external factors. This solves the problem in existing technologies where the paper edges at the groove cannot be sealed or the sealing effect is poor when the packaged candy passes through the heat-sealing channel.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0025] like Figure 1-5 As shown, the heat-sealing structure of a packaging machine proposed in this embodiment includes a lifting and pressing module, a horizontal pushing module, and a heat-sealing module. The heat-sealing module includes an adjusting plate 12, which is connected to the horizontal pushing module via a mounting plate 13. The mounting plate 13 has an elongated hole for adjusting the horizontal height of the adjusting plate 12. A base plate 11 is fixedly connected to the outer wall of the adjusting plate 12 by screws. After the candy wrapper is completed, it is transported to the same plane as the heat-sealing module by the lifting and pressing module. During the lifting process, the pressing module also presses down on the chocolate wrapper to prevent the wrapper from being wrapped. The paper deforms and rises along with the candy wrapper blocks. After being transported to the same level as the heat-sealing module, the horizontal pushing module pushes the candy wrapper blocks into the heat-sealing module. The heat-sealing module continuously heats the heating plate. When the candy wrapper blocks pass the heating plate, the heat-sealing effect is achieved. The candy wrapper blocks are continuously pushed into the heat-sealing device and arranged in an orderly manner. After a certain number are reached, the foremost chocolate wrapper block reaches the discharge port and slides into the discharge hopper. The lifting and pressing module and the horizontal pushing module are controlled by three cam linkage mechanisms to control their movement trajectory and complete the process on the corresponding sliders. The system also includes:

[0026] The guide assembly includes guide blocks 14 symmetrically fixedly connected to the top wall of the base plate 11. A heat insulation plate 8 is slidably connected to the outer wall of the guide block 14. The heat insulation plate 8 can move up and down slightly as the candy passes through, which facilitates the passage of the candy and prevents the candy from getting stuck. A heat sealing plate 7 is fixedly connected to the inner wall of the heat insulation plate 8. A heat sealing channel 15 is provided between the heat sealing plate 7, the guide block 14 and the base plate 11. The guide block 14 is designed according to the shape of the candy. The heat sealing plate 7 is made of steel plated with polytetrafluoroethylene, which has the characteristics of high temperature resistance, corrosion resistance and good electrical insulation. The feeding information sensed by the front-end sensor of the equipment is fed back to the heat sealing module through the PLC. The heat sealing plate 7 starts to heat continuously to reach the preset temperature. The heat insulation plate 8 is made of synthetic stone to isolate the high temperature on the heat sealing plate 7 and prevent it from affecting other parts of the device.

[0027] Heating components are disposed on the outer wall of the heat-sealing plate 7.

[0028] like Figure 5 As shown, in a preferred embodiment, based on the above method, the heating component further includes a protrusion 16 uniformly fixedly connected to the outer wall of the heat-sealing plate 7. The outer wall of the protrusion 16 is provided with an arc surface 9. The protrusion 16 contacts the concave surface of the candy, thereby achieving the sealing effect. After the candy enters the heat-sealing channel 15, the concave surface of the candy can contact the protrusion 16 of the heat-sealing plate 7, thereby achieving the sealing effect.

[0029] like Figure 1 As shown, in a preferred embodiment, based on the above method, the lifting and pressing module further includes a lower top block 1 fixedly connected to the outer wall of the lifting slider 17 and an upper pressing block 2 fixedly connected to the outer wall of the pressing slider 10. The outer wall of the upper pressing block 2 is slidably connected with symmetrically distributed shafts 3. The outer wall of the shafts 3 is fixedly connected with a pressure plate 4. A compression spring 5 is sleeved on the outer wall of the shafts 3, and the compression spring 5 is fixedly connected to the pressure plate 4. The end of the compression spring 5 away from the pressure plate 4 is fixedly connected to the upper pressing block 2. The compression spring 5 is used to apply a continuous force to the chocolate wrapper block when it is lifted, so as to prevent the chocolate wrapper from deforming and to press it tightly.

[0030] like Figure 2 As shown, in a preferred embodiment, based on the above method, the horizontal push module further includes a candy pusher 6 fixed to the horizontal pusher slider by fasteners, and the candy pusher 6 pushes the candy to move.

[0031] like Figure 4 As shown, in a preferred embodiment, based on the above method, a handle 18 is further fixedly connected to the outer wall of the heat insulation plate 8.

[0032] Specifically, when the heat sealing structure of this packaging machine is in use: when the candy is pushed into the heat sealing channel 15 through the candy pusher 6, the groove of the candy comes into contact with the protrusion 16 on the heat sealing plate 7, and the heat generated by the heat sealing plate 7 is transferred to the protrusion 16 and heat-sealed at the groove of the candy, thereby achieving the effect of sealing the groove of the candy.

[0033] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the invention, are covered within the scope of the claims of the present utility model.
