Description

Technical Field

[0001] The utility model relates to the technical field of packaging box production equipment, in particular to a packaging box surrounding strip pressure-keeping die. Background Art

[0002] For gift boxes, a strip is usually provided for gift packaging, such as a floor-covered gift box. Figure 1 In order to facilitate the production of packaging boxes, the gift box body 40 and the surrounding strip body 50 are usually produced separately, and then the gift box body 40 and the surrounding strip body 50 are assembled into a whole. In this regard, the production process of this type of gift box is to first apply adhesive (usually white latex) on the inner side walls of the four sides of the gift box body 40, then put the surrounding strip body 50, and then use a pressure-maintaining mold to maintain the surrounding strip body 50, so that the surrounding strip body 50 evenly presses (disperses) the adhesive, so that the surrounding strip body 50 is adhered to the inner side walls of the four sides of the gift box body 40 by the adhesive.

[0003] The inventors have found that since the existing packaging box strip pressure-keeping mold is an integral whole, when the pressure-keeping mold is used for pressure-keeping, it is easy for the strip body to be not tightly pressed, resulting in the strip body coming apart and causing the entire gift box to be scrapped. Utility Model Content

[0004] In view of the technical problem that the existing gift box pressure-keeping mold is prone to loose pressure-keeping of the strips during the strip pressure-keeping operation, the utility model provides a packaging box strip pressure-keeping mold, which can ensure that the pressure acting on the strip body is uniform, so that the strip body can fully disperse the adhesive and ensure the pressure-keeping effect, thereby reducing the scrapping of gift boxes, strips and inner trays due to debonding of the strip body and avoiding the outflow of defective gift boxes.

[0005] The utility model is realized by the following technical solutions:

[0007] The utility model provides a packaging box surrounding strip pressure-keeping mold, comprising a pressure-keeping mold main body, bubble-removing side strips and a telescopic pressurizing mechanism. The lower end of the pressure-keeping mold main body is provided with an insertion structure that can be inserted into the inner side of the surrounding strip. The bubble-removing side strips are longitudinally arranged on both sides of the insertion structure, and the bubble-removing side strips can move laterally relative to the insertion structure. The telescopic pressurizing mechanism is transmission-connected with the bubble-removing side strips, and when the telescopic pressurizing mechanism extends, the telescopic pressurizing mechanism can apply a lateral force to the bubble-removing side strips.

[0008] When in use, the pressure-holding mold body is installed on the production line of the packaging box, or installed on a dedicated rack, so that the packaging box can be located below the pressure-holding mold body, and then the package after dispensing and preliminary bonding of the surrounding strips is sent to the bottom of the pressure-holding mold body (usually transported by a conveyor belt), and then the pressure-holding mold body is driven downward by the lifting drive, so that the insertion structure is inserted into the inner side of the surrounding strip, and then through the extension action of the telescopic pressurizing mechanism, the bubble-removing side strips on both sides of the insertion structure are simultaneously applied with force, thereby driving the bubble-removing side strips to squeeze the surrounding strip body outward, and then applying outward pressure to the surrounding strip body, so that the surrounding strips press the adhesive and fully contact the side wall of the packaging box, ensuring that the surrounding strip is firmly attached to the inside of the gift box. The telescopic pressurizing mechanism applies a lateral force to the bubble-removing side strips, which can make the strength of the mold pressure-holding surrounding strips more uniform.

[0009] In summary, the packaging box strip pressure-keeping mold provided by the utility model can ensure that the pressure acting on the strip body is uniform, so that the strip body can fully disperse the adhesive and ensure the pressure-keeping effect, thereby reducing the scrapping of gift boxes, strips, and inner trays due to debonding of the strip body and avoiding the outflow of defective gift boxes.

[0014] In an optional embodiment of the utility model, the telescopic support strips and the debubble side strips are both integrated structures to simplify the structure of the pressure-maintaining mold, while also ensuring that the debubble side strips simultaneously apply pressure to the corresponding side walls of the surrounding strip body to remove bubbles.

[0015] In an optional embodiment of the utility model, the elastic connection assembly includes: a guide column, one end of which is fixedly connected to the telescopic support strip, and the other end of which extends laterally and can extend into the side wall of the insertion structure; a compression spring, one end of which is connected to the debubble side strip, and the other end of which is connected to the guide column, so that the telescopic support strip can provide lateral guidance to the telescopic support strip while applying pressure to the debubble side strip.

[0038] Example

[0039] Combination Figure 2 and Figure 3The present embodiment provides a packaging box surrounding strip pressure-keeping mold, comprising: a pressure-keeping mold body 10, wherein the lower end of the pressure-keeping mold body 10 is provided with an insertion structure 11 that can be inserted into the inner side of the surrounding strip; a bubble-removing side strip 20, wherein the bubble-removing side strip 20 is longitudinally arranged on both sides of the insertion structure 11, and the bubble-removing side strip 20 can move laterally relative to the insertion structure 11; a telescopic pressurizing mechanism 30, wherein the telescopic pressurizing mechanism 30 is transmission-connected to the bubble-removing side strip 20, and when the telescopic pressurizing mechanism 30 is extended, the telescopic pressurizing mechanism 30 can apply a lateral force to the bubble-removing side strip 20, thereby pressing the bubble-removing side strip 20 against the surrounding strip body 50.

[0040] It is understandable that the insertion structure 11 is inserted into the inner side of the surrounding strip during the working process, so its cross-sectional size is adapted to the cross-sectional size of the processed packaging box. That is, the size of the insertion structure 11 is determined according to the processed packaging box. At the same time, a groove for accommodating the de-bubble side strip 20 is provided on the side wall of the insertion structure 11 in the longitudinal direction (since the packaging box is usually rectangular, in this embodiment, the longitudinal direction refers to the length direction of the packaging box, and the transverse direction refers to the width direction of the packaging box), so that in the initial state, the shape surrounded by the insertion structure 11 and the de-bubble side strip 20 is adapted to the shape of the surrounding strip of the processed packaging box, ensuring that the insertion structure 11 and the de-bubble side strip 20 can be inserted into the inner side of the surrounding strip according to the set depth (the lower end of the insertion structure 11 usually contacts the bottom of the inner cavity of the box body / box cover of the packaging box).

[0041] In this embodiment, a heightened connecting block 12 is provided at the upper end of the pressure-maintaining mold body 10, and a cavity for accommodating the telescopic pressurizing mechanism 30 is provided in the heightened connecting block 12, the pressure-maintaining mold body 10 and the insert structure 11, so as to facilitate connecting the pressure-maintaining mold body 10 with the corresponding lifting drive, while avoiding interference of the telescopic pressurizing mechanism 30 with the lifting drive.

[0042] Therefore, it can be understood that the telescopic pressurizing mechanism 30 is disposed inside the pressure-maintaining mold body 10 to prevent the telescopic pressurizing mechanism 30 from interfering with the surrounding strip body 50 and crushing the surrounding strip body 50 during the surrounding strip pressure-maintaining operation. The heightening connecting block 12 is usually in a "convex" shape to reduce the volume of the heightening connecting block 12.

[0043] Correspondingly, through grooves communicating with the inner cavity of the heightened connecting block 12 are provided on both longitudinal sides of the heightened connecting block 12 to facilitate the installation and maintenance of the telescopic pressurizing mechanism 30 and the routing of the telescopic pressurizing mechanism 30 (air pressure pipeline or power control line, etc.).

[0044] Combination Figure 4 and Figure 5The telescopic pressurizing mechanism 30 includes: a telescopic support bar 31, which is arranged one-to-one with the defoaming side bar 20; an elastic connecting component 32, which is arranged between the telescopic support bar 31 and the corresponding defoaming side bar 20, and the elastic connecting component 32 is arranged at intervals along the length direction of the corresponding telescopic support bar 31; a telescopic support bar 33, which can move up and down, and in the process of the telescopic support bar 33 moving downward, it can be inserted between the two telescopic support bars 31 arranged in a laterally corresponding manner to apply a lateral force to the corresponding defoaming side bar 20; a telescopic driver 34, which is transmission-connected with the telescopic support bar 33 to ensure that the telescopic pressurizing mechanism 30 can apply sufficient pressure to the defoaming side bar 20 while reducing the lateral size of the telescopic pressurizing mechanism 30, so that the telescopic pressurizing mechanism 30 can be installed in the pressure-maintaining mold body 10.

[0045] It should be understood that the telescopic support strip 31 and the defoaming side strip 20 are both integrated structures to simplify the structure of the pressure-maintaining mold, and can also ensure that the defoaming side strip 20 simultaneously applies pressure to the side wall corresponding to the surrounding strip body 50 to remove bubbles. Of course, multiple defoaming side strips 20 can also be provided.

[0046] Combine again Figure 5 The elastic connection component 32 includes: a guide column 32a, one end of which is fixedly connected to the telescopic support strip 31, and the other end of which extends laterally and can extend into the side wall of the insertion structure 11; a compression spring 32b, one end of which is connected to the defoaming side strip 20, and the other end of which is connected to the guide column 32a (usually fixedly sleeved outside the end of the guide column 32a), so that the telescopic support strip 31 can provide lateral guidance to the telescopic support strip 31 while applying pressure to the defoaming side strip 20.

[0047] It should be noted that the telescopic support bar 33 is a wedge-shaped block structure with a larger upper portion and a smaller lower portion, so that the telescopic support bar 33 can simultaneously apply lateral pressure to the telescopic support bars 31 on both sides during the downward movement. The inner upper edges of the two telescopic support bars 31 are rounded or chamfered to facilitate the assembly of the telescopic support bar 33 between the two telescopic support bars 31.

[0048] In this embodiment, the telescopic driver 34 is a pneumatic cylinder to provide power to the telescopic driver 34. Of course, an electric push rod, a linear drive mechanism driven by a motor, etc. can also be used as the telescopic driver 34.

[0049] In addition, the outer edges of the lower ends of the bubble-removing side strips 20 and the insert structure 11 are rounded to prevent the pressure-maintaining mold from damaging the surrounding strip body 50 during operation.

[0050] In summary, the packaging box surrounding strip pressure-keeping mold provided in the present embodiment includes a pressure-keeping mold body 10, a bubble-removing side strip 20 and a telescopic pressurizing mechanism 30. The lower end of the pressure-keeping mold body 10 is provided with an insertion structure 11 which can be inserted into the inner side of the surrounding strip. The bubble-removing side strips 20 are longitudinally arranged on both sides of the insertion structure 11, and the bubble-removing side strip 20 can move laterally relative to the insertion structure 11. The telescopic pressurizing mechanism 30 is transmission-connected with the bubble-removing side strip 20, and when the telescopic pressurizing mechanism 30 is extended, the telescopic pressurizing mechanism 30 can apply a lateral force to the bubble-removing side strip 20.

[0051] When in use, the pressure-holding mold body 10 is installed on the production line of the packaging box, or on a dedicated rack, so that the packaging box can be located below the pressure-holding mold body 10, and then the package after dispensing and preliminary bonding of the surrounding strips is sent to the bottom of the pressure-holding mold body 10 (usually transported by a conveyor belt), and then the pressure-holding mold body 10 is driven downward by the lifting drive, so that the insertion structure 11 is inserted into the inner side of the surrounding strip, and the bubble-removing side strip 20 is opposite to the inner side wall of the corresponding long side of the surrounding strip, and then the application drive drives the telescopic support bar 33 to move downward, thereby simultaneously driving the telescopic support bar 31 to move laterally outward through the telescopic support bar 33, so as to compress the compression spring 32b and synchronously apply a force to the bubble-removing side strips 20 on both sides of the insertion structure 11, thereby driving the bubble-removing side strips 20 to squeeze the surrounding strip body 50 outward, and then applying outward pressure to the surrounding strip body 50, so that the surrounding strip presses the adhesive and fully contacts the side wall of the packaging box, ensuring that the surrounding strip is firmly adhered to the inside of the gift box. The telescopic pressurizing mechanism 30 applies a lateral force to the defoaming side strips 20, so that the strength of the mold pressure-maintaining strips can be more uniform.

[0052] In summary, the packaging box strip pressure-maintaining mold provided in this embodiment can ensure that the pressure acting on the strip body 50 is uniform, so that the strip body 50 can fully disperse the adhesive and ensure the pressure-maintaining effect, thereby reducing the scrapping of gift boxes, strips, and inner trays due to the debonding of the strip body 50 and avoiding the outflow of defective gift boxes.

[0053] The specific implementation methods 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 the specific implementation method of the utility model and is not used to limit the protection scope of the utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
