[0042] like Figures 1 to 3 As shown, the utility model provides a box pressing device of a case packing machine, which includes: an upper circulating chain group A, having a first chain group 10, on which a pressing plate 12 is provided; a lower conveying chain group B, which is arranged below the upper circulating chain group A, and the lower conveying chain group B has a second chain group 20 for fixing and conveying a box 40, and a conveying channel C is formed between the first chain group 10 and the second chain group 20; wherein, the box 40 has a box body 41 and a swing cover 42 connected to the box body 41, and along the length direction of the swing cover 42, the pressing plate 12 can extend to the two side edges of the swing cover 42, and when the box 40 is running in the conveying channel C, the pressing plate 12 can be pressed on the free end of the swing cover 42 to make it bonded to the box body 41.

[0043] The box pressing device of the cartoning machine described in the present invention is provided with a pressing plate 12 on the first chain group 10 located on the upper side of the box 40. The pressing plate 12 can generate a certain pressing force on all bonding positions on the swing cover 42 during the bonding and packaging process of the box 40, so that the swing cover 42 is firmly bonded to the box body 41 through hot melt adhesive, avoiding quality risks caused by debonding.

[0044] The box pressing device of the packing machine described in the utility model can eliminate the problem of the box 40 being debonded after packaging by optimizing the design of the corresponding pressing device during the covering process, and the overall strength and stability of the box 40 will be significantly improved; the firm glue point adhesion formed by the improved pressing device can also effectively prevent the product from being damaged or scattered during transportation and handling, further improving the safety and integrity of the product, making the product packaging more solid and safe. The box 40 produced by the above equipment has better quality, bringing consumers a more high-quality and stable packaging experience.

[0045] The following will describe in detail the various structures of the box pressing device of the box packing machine of the present invention and the positional relationship and connection relationship between the various structures.

[0046] First, if Figure 3 As shown, the box pressing device is used to produce a box 40 having a box body 41 and a swing cover 42. The box 40 is usually a cubic shell made of paper. The box body 41 is a paper trough with an opening at the top, in which the product is placed. A swing cover 42 capable of closing the opening is connected to one side wall of the box body. The swing cover 42 can be bonded to the adhesive strip 43 on the box body 41 by bonding, thereby closing the box body 41 and completing the packaging operation on the top of the box 40. The box pressing device described in the utility model is mainly used for the bonding and packaging process of the adhesive strip 43 on the box body 41 and the swing cover 42.

[0047] Secondly, if Figure 1 As shown, the box pressing device mainly includes an upper circulation chain group A and a lower conveying chain group B which are relatively arranged in an upper and lower direction, and a conveying channel C is formed between the upper circulation chain group A and the lower conveying chain group B. The box 40 is continuously conveyed forward in the conveying channel C, and during the conveying process, the upper circulation chain group A and the lower conveying chain group B cooperate to achieve stable bonding between the swing cover 42 and the box body 41.

[0048] Further, such as Figure 1 and Figure 2 As shown, the lower conveying chain group B has a second chain group 20, and the second chain group 20 has a plurality of second chains 21 arranged in parallel. The size and running speed of the plurality of second chains 21 are the same. The box 40 is fixed on the plurality of second chains 21 and can be conveyed forward in the conveying channel C under the drive of the plurality of second chains 21; the arrangement of the plurality of second chains 21 can improve the stability of the box 40 during the conveying process. In this embodiment, as Figure 1 As shown, three second chains 21 are arranged below the box body 40; the number of the second chains 21 can be set according to actual needs and is not specifically limited here.

[0049] like Figure 1 and Figure 2 As shown, the upper circulating chain group A has a first chain group 10, and the first chain group 10 has a plurality of first chains 11 arranged in parallel, and the plurality of first chains 11 have the same size and running speed, and a pressing plate 12 is provided on the plurality of first chains 11, and the pressing plate 12 can run with the first chains 11; the plurality of first chains 11 can improve the stability of the first chain group 10 during operation, and can also improve the stability of the pressure applied to the swing cover 42 by the pressing plate 12 during operation. In this embodiment, as Figure 1 As shown, two first chains 11 are arranged above the box body 40; the number of the first chains 11 can be set according to actual needs and is not specifically limited here.

[0050] Furthermore, Figure 1 and Figure 2 As shown, the pressing plate 12 is a long steel plate extending along the length direction of the swing cover 42, and the two ends of the long steel plate extend to the two side edges of the swing cover 42 respectively; the pressing plate 12 is made of 304 stainless steel. On the basis of being able to realize the pressing function, the pressing plate has a relatively simple structure, low cost, and will not affect the operation of the case packing machine. Bolt connection holes are opened at the positions of the two first chains 11 corresponding to the pressing plate 12, and the pressing plate 12 is detachably connected to the two first chains 11 by bolts.

[0051] When the box body 40 is pressed, first, Figure 3 As shown, at this time, the swing cover 42 of the box body 40 is not bonded to the box body 41. As the box body 40 moves forward, in the conveying channel C, the swing cover 42 is gradually pressed toward the box body 41 under the action of the upper first chain group 10 to close the top opening; when the swing cover 42 rotates to completely cover the box body 41 during the forward movement, as shown in FIG. Figure 2 As shown, at this time, the pressing plate 12 can just be pressed on the other end (free end) of the swing cover 42 away from the end connected to the box body 41, and the free end of the swing cover 42 can be fitted with a section of adhesive strip 43 on the side wall of the box body 40. The adhesive strip 43 is pre-sprayed or coated with hot melt adhesive on the side facing the swing cover 42. Under the action of the pressing plate 12, the swing cover 42 can achieve the closure of the box body 41 by bonding with the adhesive strip 43. And the pressing plate 12 is extended along the length direction of the swing cover 42 (the length direction of the adhesive strip 43) and can extend to the two side edges of the swing cover 42, that is, the pressing plate 12 can generate a pressing force on the entire bonding range of the swing cover 42, so that it can be stably connected with the adhesive strip 43, avoiding the situation that the bonding is not firm at some positions due to insufficient downward pressing range.

[0052] The structure of the preferred embodiment of the box pressing device of the case packing machine of the utility model and the technical effects that can be brought about will be further described below.

[0053] According to one embodiment of the present utility model, Figure 2 and Figure 3 As shown, the end surface of the pressing plate 12 that can contact the swing cover 42 is the pressing surface, and the edges of the pressing surface are formed with a rounded structure. The edges of the pressing surface where the pressing plate 12 contacts the swing cover 42 are provided with corresponding rounded structures to avoid scratching the surface of the swing cover 42 when the pressing plate 12 acts on the swing cover 42.

[0054] According to one embodiment of the present utility model, Figures 1 to 3 As shown, a box supporting plate 13 is also provided on the first chain group 10. The box supporting plate 13 is arranged adjacent to the pressing plate 12. The box supporting plate 13 has two perpendicular supporting surfaces. When the box body 40 is running in the conveying channel C, the two supporting surfaces are respectively abutted against the side walls of the rocker cover 42 and the free end of the box body 41 close to the rocker cover 42.

[0055] The supporting plate 13 can correct the side wall position of the box body 40 during the packaging process of the box body 40, so that the side wall and the swing cover 42 are perpendicular to each other, avoiding misalignment between the box body 41 and the swing cover 42, which in turn causes a loose bond between the swing cover 42 and the box body 41.

[0056] Specifically, the box support plate 13 is a steel plate with an L-shaped cross section, which is detachably fixed to the two first chains 11 by bolts, and is disposed adjacent to the pressing plate 12. The box support plate 13 includes two vertically stabilizing walls, and the inner side surfaces of the two vertically stabilizing walls respectively form the above-mentioned two stabilizing surfaces. Figure 2 As shown, the box supporting plate 13 can straighten the right angle formed at the bonding position of the box body 41 and the swing cover 42 when the swing cover 42 is rotated to completely cover the box body 41, so as to avoid misalignment between the box body 41 and the swing cover 42. The box supporting plate 13 is a conventional structure provided on the case packing machine for straightening the box body 40 at the right angle position, and the structure and function of the box supporting plate 13 will not be described in more detail here.

[0057] According to one embodiment of the present utility model, Figure 1 As shown, the upper circulating chain group A also has a third chain group 30, which is parallel to the first chain group 10. The third chain group 30 includes two third chains 31 respectively arranged on both sides of the first chain group 10, and the third chains 31 are provided with pressure blocks 32. When the box body 40 is running in the conveying channel C, the two pressure blocks 32 on the two third chains 31 can be pressed on both sides of the swing cover 42.

[0058] The pressing block 32 arranged on the third chain group 30 can generate a certain pressing force on the two sides of the swing cover 42 during the bonding and packaging process of the box body 40, so that it maintains close contact with the box body 41, thereby avoiding misalignment between the swing cover 42 and the box body 41.

[0059] Specifically, Figure 1 and Figure 3 As shown, one long side of the swing cover 42 is connected to the box body 41, and the other long side (free end) and two short sides thereof need to be connected to the box body 41 by bonding or other means, and during the packaging process of the box body 40, it is necessary to ensure that the long side and two side sides can be aligned with the corresponding side walls on the box body 40, and no misalignment can occur. Among them, the long side of the swing cover 42 can be straightened and limited by the action of the pressing plate 12 and the box supporting plate 13; therefore, in order to limit the two side sides of the swing cover 42, a third chain group 30 is arranged outside the first chain group 10, and the two third chains 31 in the third chain group 30 are respectively located outside the two first chains 11, and the two third chains 31 are respectively arranged near the two sides of the swing cover 42; a pressing block 32 is arranged on the third chain 31, and the pressing block 32 is extended along the width direction of the box supporting plate 13. When the swing cover 42 is rotated to completely cover the box body 41 , the pressing blocks 32 can be pressed on both sides of the swing cover 42 , so that the swing cover 42 and the box body 41 fit tightly.

[0060] According to an embodiment of the utility model, the running direction of the first chain set 10 is the same as the running direction of the third chain set 30, and the running speed of the first chain set 10 is the same as the running speed of the third chain set 30; along the running direction perpendicular to the box body 40, a pressing plate 12 is provided at the corresponding position of the first chain set 10 between every two pressing blocks 32. During the pressing operation of the box body 40, the two pressing blocks 32 and one pressing plate 12 cooperate with each other and are pressed on the three sides of the swing cover 42 respectively, ensuring that the relative position thereof will not be deflected during the pressing and bonding process, and at the same time ensuring the firmness of the bonding between the swing cover 42 and the box body 41.

[0061] According to an embodiment of the present invention, along the length direction of the first chain group 10, a plurality of pressing plates 12 are arranged at intervals on the first chain group 10, and along the length direction of the third chain group 30, a plurality of pressing blocks 32 are arranged at intervals on the third chain 31. The plurality of pressing plates 12 and the plurality of pressing blocks 32 that cooperate with each other can realize the continuous bonding and packaging operation of the box body 40.

[0062] The specific embodiments described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only a specific embodiment of the utility model and is not intended to limit the scope of protection of the utility model.
