Description

Technical Field

[0001] The utility model relates to the technical field of packing box production equipment, in particular to a folding and forming device for a support card used in packing box production. Background Technique

[0002] The packing box support card refers to a support and buffer member arranged on the side wall of the packing box, which can support the side wall of the packing box and buffer the goods. It is usually arranged on two opposite sides of the packing box and belongs to the accessories of the packing box. Most of the existing packing box support cards are cardboard pieces, which are folded and formed from flat cardboard cut into the required shape. Figure 1 Generally, score lines are arranged on the surface of the raw cardboard of the support card to facilitate folding. At the same time, mutually adapted card slots and buckles are arranged on two opposite sides of the raw cardboard of the support card, so that the folded and formed support card can maintain the required shape through the cooperation of the card slot and the buckle.

[0003] That is to say, most of the support cards of packing boxes are folded and formed by manually folding along the score lines of the support cards. After forming, the buckles are snapped and fixed to prevent the support card from falling apart due to the resilience. However, when manually buckling the support card, because the support card is relatively thick, it is difficult to fold, and the operator is extremely prone to fatigue, resulting in low production efficiency and a waste of a large amount of human resources. Therefore, automated equipment capable of automatically producing support cards is needed. Content of the Utility Model

[0004] Aiming at the technical problem of low production efficiency of manually producing support cards, the utility model provides a folding and forming device for a support card used in packing box production, which can automatically fold and form the raw cardboard of the support card after gluing, thereby improving the production efficiency of the packing box support card and reducing the waste of human resources.

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

[0006] The present utility model provides a support card folding and forming device for the production of packing boxes, comprising: a support card forming plate for supporting the inner side wall of the support card when folding the support card; a support card bearing platform for carrying the support card raw material; a transfer linear drive module for driving the support card bearing platform to move linearly so as to move the support card bearing platform below the support card forming plate; a lifting and folding assembly including a lifting and folding linear driver and a folding and forming die, the lifting and folding linear driver being used to lift the folding and forming die outside the support card forming plate so as to fold both sides of the support card; a side pressing and folding assembly including a side pressing and folding die and a side pressing linear driver, the side pressing linear driver being used to drive the side pressing and folding die to move towards one side above the support card forming plate so as to side press the upper part of one side of the support card; and a side pressing and fitting assembly including a side pressing roller and a fitting linear driver, the fitting linear driver being used to drive the side pressing roller to move towards the other side above the support card forming plate so as to side press the upper part of the other side of the support card and press and bond the support card.

[0007] Since, after the support card is folded and formed, the resilience is extremely large, and it is easier to bounce open in a non-buckling manner. Therefore, most support cards are provided with mutually adapted card slots and buckles on two opposite sides of the raw cardboard of the support card, so that through the cooperation of the card slots and the buckles, the folded and formed support card can maintain the required shape, so as to obtain higher buckling stability and buffering performance. However, when manually buckling the support card, due to the relatively thick support card, folding is difficult, and the operator is extremely prone to fatigue, resulting in low production efficiency and a waste of a large amount of human resources.

[0008] In view of this, the present utility model provides a support card folding and forming device for the production of packing boxes, comprising a support card forming plate, a support card bearing platform, a transfer linear drive module, a lifting and folding assembly, a side pressing and folding assembly and a side pressing and fitting assembly; the support card forming plate can support the inner side wall of the support card when folding the support card; the support card bearing platform is used for carrying the support card raw material; the transfer linear drive module is used for driving the support card bearing platform to move linearly so as to move the support card bearing platform below the support card forming plate; the lifting and folding assembly includes a lifting and folding linear driver and a folding and forming die, the lifting and folding linear driver being used to lift the folding and forming die outside the support card forming plate so as to fold both sides of the support card; the side pressing and folding assembly includes a side pressing and folding die and a side pressing linear driver, the side pressing linear driver being used to drive the side pressing and folding die to move towards one side above the support card forming plate so as to side press the upper part of one side of the support card; the side pressing and fitting assembly includes a side pressing roller and a fitting linear driver, the fitting linear driver being used to drive the side pressing roller to move towards the other side above the support card forming plate so as to side press the upper part of the other side of the support card and press and bond the support card.

[0009] During use, the feeding linear drive module drives the support card bearing platform to move, so that the support card bearing platform moves to the feeding station to receive the support card raw material through the support card bearing platform. Then, the feeding linear drive module drives the support card bearing platform to move to the folding station. Next, the lifting and folding linear driver lifts the folding and forming die, lifting the folding and forming die outside the support card forming plate, causing both sides of the support card raw material to fold along both sides of the length direction of the support card forming plate to fold both sides of the support card. At this time, both sides of the support card raw material are in a vertical state. Then, the side pressure linear driver drives the side pressure folding die to move to one side above the support card forming plate, folding and pressing the upper part of the corresponding side wall of the support card raw material onto the support card forming plate. Then, the fitting linear driver drives the side pressure roller to move to the other side above the support card forming plate, folding and pressing the upper part of the other side wall of the support card raw material onto the support card forming plate and onto the side wall of the opposite support card raw material. And an adhesive is disposed on the support card raw material. When the support card raw material is side-pressed, the adhesive can be dispersed, so that both sides of the support card raw material are adhered to complete the folding and forming of the support card.

[0010] Among them, for applying glue to the support card raw material, it can be carried out after the support card raw material is placed on the support card bearing platform, or it can be carried out during the process of the feeding linear drive module driving the support card bearing platform to move to the folding station.

[0011] Therefore, the utility model can automatically fold and form the support card cardboard after dispensing glue, thereby improving the production efficiency of the packaging box support card and reducing the waste of human resources.

[0012] In an optional embodiment of the present application, the support card bearing platform is adapted with a suction cup to fix the support card raw material on the support card bearing platform through the suction cup, avoiding the support card raw material moving relative to the support card bearing platform or falling when the feeding linear drive module drives the support card bearing platform to move, which affects the production of the support card.

[0013] In an optional embodiment of the present application, the support card bearing platform includes: a bearing platform body for carrying the support card raw material; an installation base fixed on the moving part of the feeding linear drive module; and a pressure maintaining linear driver installed on the installation base. The pressure maintaining linear driver is used to push the bearing platform body downward on the lower side of the support card forming plate, which can increase the pressure maintaining force of the side pressure roller and the support card forming plate on the support card, fully disperse the adhesive, ensure the reliability of the adhesion of both sides of the support card, and avoid the support card from coming unstuck.

[0014] In an alternative embodiment of the present application, two pressure-holding linear drivers are provided, and the two pressure-holding linear drivers are respectively connected to the corresponding ends in the length direction of the bearing platform body, so as to ensure that the bearing platform body can be fully pressed against the support card forming plate, and avoid deflection of the bearing platform body during movement and pressing.

[0015] In an alternative embodiment of the present application, a pressing linear driver is further included. The moving end of the pressing linear driver can move above the support card forming plate to press the formed support card against the support card forming plate, so as to avoid the movement of the support card relative to the support card forming plate before pressure holding.

[0016] In an alternative embodiment of the present application, the lifting and folding assembly is installed on the installation base, so as to facilitate the installation of the lifting and folding assembly and avoid interference with the operation of the transfer linear drive module.

[0017] In an alternative embodiment of the present application, the folding and forming die is of a U-shaped structure to ensure that the folding and forming die can fold both sides of the support card raw material at the same time.

[0018] In an alternative embodiment of the present application, the side pressing and folding assembly further includes a side pressing and lifting device, which is used to drive the side pressing linear driver to move vertically, so as to drive the side pressing linear driver to move vertically through the side pressing and lifting device, and move the side pressing and folding die below the support card forming plate, facilitating the movement of the next support card forming plate to the folding station.

[0019] In an alternative embodiment of the present application, the side pressing and folding die is of a shovel blade type structure to reduce the friction between the side pressing and folding die and the support card raw material while ensuring that the side pressing and folding die can side press the support card raw material.

[0020] In an alternative embodiment of the present application, the side pressing and fitting assembly further includes a side pressing and fitting lifting device, which is used to drive the fitting linear driver to move vertically, so as to drive the fitting linear driver to move vertically through the side pressing and fitting lifting device, and move the side pressing roller below the support card forming plate, facilitating the removal of the support card forming plate sleeved with the formed support card from the folding station.

Detailed implementation manners

[0035] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. Usually, the components of the embodiments of the present application described and illustrated in the accompanying drawings here can be arranged and designed in various different configurations.

[0036] It should be noted that: Similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. Without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0037] In the description of the embodiments of the present application, the indicated orientation or positional relationship is based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the product of this application is usually placed during use, or the orientation or positional relationship commonly understood by those skilled in the art. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application.

[0038] In the description of the present utility model, unless otherwise clearly specified and limited, the terms "arranged", "installed", "connected", and "coupled" shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0039] Please refer to Figure 1 , after the support card is folded and formed, the rebound force is extremely large, and it is relatively easy to bounce open in a non-snap manner. Most of the existing packaging box support cards are cardboard pieces, which are folded and formed from flat cardboard cut into the required shape. And knife lines are provided on the surface of the raw cardboard of the support card to facilitate folding. At the same time, mutually adapted slots and snaps are provided on two opposite sides of the raw cardboard of the support card, so that the support card after folding and forming can maintain the required shape through the cooperation of the slots and snaps, so as to obtain higher snap-in stability and buffering performance. However, when manually snapping the support card, due to the relatively thick support card, it is difficult to fold, and the operator is extremely prone to fatigue, resulting in low production efficiency and waste of a large amount of human resources.

[0040] Combined with Figure 2 , in a feasible solution, an adhesive or adhesive strip is arranged on the upper end surface of one side of the raw material of the support card. For example, a double-sided tape is used for manual line pasting, or white latex is brushed, and then the upper end surfaces of both sides of the raw material of the support card are bonded together to form a complete support card. Although the snap is cancelled, manual folding and forming still have the problem of relatively low production efficiency.

[0041] In order to solve the above-mentioned problems, the inventor innovatively designs the following technical solutions. The specific implementation solutions of the present application will be described in detail below with reference to the drawings.

[0042] Embodiment

[0043] Combined with Figures 3 - 7, this embodiment provides a support card folding and forming device for packaging box production, including: a support card forming plate 210 for supporting the inner wall of the support card when folding the support card; a support card bearing platform 310 for carrying the support card raw material; a transfer linear drive module 320 for driving the support card bearing platform 310 to move linearly to move the support card bearing platform 310 below the support card forming plate 210; a lifting and folding assembly 330 including a lifting and folding linear driver 331 and a folding and forming die 332, where the lifting and folding linear driver 331 is used to lift the folding and forming die 332 outside the support card forming plate 210 to fold both sides of the support card; a side pressing and folding assembly 340 including a side pressing and folding die 341 and a side pressing linear driver 342, where the side pressing linear driver 342 is used to drive the side pressing and folding die 341 to move to one side above the support card forming plate 210 to side press the upper part of one side of the support card; a side pressing and fitting assembly 350 including a side pressing roller 351 and a fitting linear driver 352, where the fitting linear driver 352 is used to drive the side pressing roller 351 to move to the other side above the support card forming plate 210 to side press the upper part of the other side of the support card and press and bond the support card.

[0044] It can be understood that the cross-sectional shape of the support card forming plate 210 is adapted to the cross-section of the inner cavity of the support card. When the support card is pressed and folded along the edge in the length direction of the support card forming plate 210, the support card raw material can be formed into the required support card. And after the support card is formed, it is sleeved on the support card forming plate 210. Therefore, after the support card is formed, it needs to be removed from the support card forming plate 210.

[0045] Combined with Figure 4 , the support card bearing platform 310 is equipped with a suction cup 311 to fix the support card raw material on the support card bearing platform 310 through the suction cup 311, avoiding the movement or dropping of the support card raw material relative to the support card bearing platform 310 when the transfer linear drive module 320 drives the support card bearing platform 310 to move, which affects the production of the support card.

[0046] Specifically, the support card bearing platform 310 includes: a bearing platform body 312 for bearing the support card raw material; a mounting base 313 fixed on the moving part of the material transfer linear drive module 320; a pressure-holding linear driver 314 mounted on the mounting base 313, and the pressure-holding linear driver 314 is used to push the bearing platform body 312 downward from the lower side of the support card forming plate 210, which can increase the pressure-holding force of the side pressure roller 351 and the support card forming plate 210 on the support card, fully disperse the adhesive, ensure the reliability of the adhesion on both sides of the support card, and avoid the support card from coming unstuck.

[0047] It should be understood that two pressure-holding linear drivers 314 are provided, and the two pressure-holding linear drivers 314 are respectively connected to the corresponding ends in the length direction of the bearing platform body 312 to ensure that the bearing platform body 312 can be fully pressed against the support card forming plate 210 and avoid skewing of the bearing platform body 312 during movement and pressing.

[0048] Combined with Figure 5 , the jacking and folding assembly 330 is mounted on the mounting base 313 to facilitate the installation of the jacking and folding assembly 330 and avoid interference of the jacking and folding assembly 330 with the operation of the material transfer linear drive module 320.

[0049] Among them, the folding and forming die 332 is of a U-shaped structure to ensure that the folding and forming die 332 can fold both sides of the support card raw material at the same time.

[0050] In this embodiment, the side pressure and folding assembly 340 further includes a side pressure jacking device 343, and the side pressure jacking device 343 is used to drive the side pressure linear driver 342 to move vertically, so as to drive the side pressure linear driver 342 to move vertically through the side pressure jacking device 343 and move the side pressure folding die 341 below the support card forming plate 210 to facilitate moving the next support card forming plate 210 to the folding station.

[0051] Combined with Figure 6 and Figure 7 , the side pressure folding die 341 is of a shovel-shaped structure to reduce the friction between the side pressure folding die 341 and the support card raw material while ensuring that the side pressure folding die 341 can side-press the support card raw material.

[0052] It can be understood that the side pressure laminating assembly 350 further includes a side pressure laminating lifter 353, which is used to drive the laminating linear driver 352 to move vertically, so as to drive the laminating linear driver 352 to move vertically through the side pressure laminating lifter 353, and move the side pressure roller 351 below the support card forming plate 210, facilitating the removal of the support card forming plate 210 sleeved with the formed one from the folding station.

[0053] On this basis, this embodiment further includes a pressing linear driver 360, and the moving end of the pressing linear driver 360 can move above the support card forming plate 210 to press the formed support card on the support card forming plate 210, preventing the support card from moving relative to the support card forming plate 210 before pressure holding.

[0054] It should be noted that for each linear driver and lifter, it only needs to be able to drive the corresponding component to move linearly. It can be an electric push rod, a hydraulic rod, or other linear drive mechanisms, such as a synchronous pulley drive mechanism driven by a motor, a rack and pinion mechanism, a lead screw slider mechanism, etc. In the embodiment, each linear driver and lifter is a slide cylinder. At the same time, the transfer linear drive module 320 is a commonly used electric linear drive module in the non-standard automation field.

[0055] In summary, the support card folding and forming device for packaging box production provided in this embodiment includes a support card forming plate 210, a support card bearing platform 310, a transfer linear drive module 320, a lifting and folding assembly 330, a side pressure folding assembly 340, a side pressure laminating assembly 350, and a pressing linear driver 360.

[0056] During use, the transfer linear drive module 320 drives the support card bearing platform 310 to move, so that the support card bearing platform 310 moves to the loading station to receive the support card raw material after dispensing, and then the transfer linear drive module 320 drives the support card bearing platform 310 to move to the folding station, making the support card raw material stuck between the bearing platform body 312 and the support card forming plate 210. Among them, for the glue application of the support card raw material, it can be carried out after the support card raw material is placed on the support card bearing platform 310, or during the process of the transfer linear drive module 320 driving the support card bearing platform 310 to move to the folding station, so as to coat the adhesive on the inner surface of the side of the support raw material facing the side pressure roller 351.

[0057] During production, a pressing plate pressing linear driver 370 is also provided. Before folding, the pressing plate pressing linear driver 370 presses against the support card forming plate 210 to prevent the support card forming plate 210 from shifting when the folding forming die 332 jacks up the support card raw material. Then, the jacking folding linear driver 331 jacks up the folding forming die 332, lifting the folding forming die 332 outside the support card forming plate 210, so that both sides of the support card raw material are folded along both sides of the length direction of the support card forming plate 210 to fold both sides of the support card. At this time, both sides of the support card raw material are in a vertical state (the adhesive is located above the support card forming plate 210). Then, the side pressing jacking device 343 drives the side pressing linear driver 342 to move upward above the corresponding side of the support card forming plate 210 in sequence, and the side pressing linear driver 342 drives the side pressing folding die 341 to move toward the upper side of the support card forming plate 210, so as to fold and press the upper part of the corresponding side wall of the support card raw material on the support card forming plate 210.

[0058] Then, the side pressing and fitting jacking device 353 drives the fitting linear driver 352 to move upward above the other side of the support card forming plate 210 in sequence, and the fitting linear driver 352 drives the side pressing roller 351 to move toward the other upper side of the support card forming plate 210, so that the upper part of the other side wall of the support card raw material is folded and pressed on the support card forming plate 210 and on the side wall of the opposite support card raw material. Since the adhesive is arranged on the support card raw material, the adhesive can be pressed and dispersed when the support card raw material is side-pressed, so that both sides of the support card raw material are adhered together, and the support card is folded and formed. During the process of the side pressing roller 351 pressing and moving toward the side pressing folding die 341, the side pressing folding die 341 retracts.

[0059] After the support card raw material is folded into the shape of the support card, the pressing and pasting linear driver 360 acts to press and paste the formed support card on the support card forming plate 210 to prevent the support card from moving relative to the support card forming plate 210 before pressure holding. Then, the pressure holding linear driver 314 drives the bearing platform body 312 to move upward, so that the bearing platform body 312 tightly presses the support card on the support card forming plate 210, increasing the pressure holding force of the side pressing roller 351 and the support card forming plate 210 on the support card, fully pressing and dispersing the adhesive, ensuring the reliability of the adhesion of both sides of the support card, and preventing the support card from coming unglued. Subsequently, all components retract to complete the support folding and forming.

[0060] In summary, the support card folding and forming device for packaging box production provided in this embodiment can automatically fold and form the original cardboard of the support card after dispensing glue, thereby improving the production efficiency of the support card of the packaging box and reducing the waste of human resources.

[0061] The specific embodiments described above further elaborate on the purpose, technical solutions, and beneficial effects of the present utility model. It should be understood that the above description is only the specific embodiments of the present utility model and is not intended to limit the protection scope of the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
