Description

Technical Field

[0001] This utility model relates to the field of packaging box edge-sealing equipment, specifically to a packaging box edge-sealing machine. Background Technology

[0002] The packaging box edge-sealing machine, also known as the packaging box edge-wrapping machine, is generally a link in the packaging box production line. It requires manual placement of the packaging box blank on the prepared outer film. On the production line, the outer film is pasted onto the packaging box by workers, who try to squeeze out the air bubbles inside the box during the process. Then, the packaging box with the outer film pasted on is placed on the edge-sealing machine for pressing, so as to seal the edges of the packaging box and squeeze out the air bubbles inside the outer film and the packaging box.

[0003] Chinese invention patent application CN201410709910.7 discloses an automatic edge-wrapping and defoaming machine. The edge-wrapping device's folding assembly is positioned above the defoaming assembly, which includes a folding plate and a folding cylinder. The edge-wrapping assembly includes a lower die that moves vertically up and down. During edge wrapping, the folding cylinder extends and retracts, the folding plate moves horizontally to bend the vertical edge of the packaging box, and the lower die, positioned directly above the packaging box, descends to adhere the bent vertical edge to the inner wall of the packaging box, thus achieving edge wrapping. During defoaming, the defoaming cylinder extends, and the defoaming plate applies pressure to the side wall of the packaging box to remove bubbles. This solution effectively performs edge folding and defoaming simultaneously; however, it does not adequately address the issue of manually bending the outer film and attaching it to the packaging box blank, still requiring manual operation and resulting in low efficiency. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of the aforementioned technologies by proposing a packaging box edge-sealing machine, which aims to solve the problem of low efficiency in manual operation of attaching outer film boxes to packaging boxes.

[0005] This utility model provides a packaging box edge-sealing machine, including a machine base, a support frame, folding push rods sliding around the packaging box, and an edge-sealing plate that extends and retracts on the support frame. A mold platform is fixedly connected to the machine base next to the folding push rods. A liftable film-applying mechanism is fixedly connected to the top of the support frame to apply the outer film to the packaging box. The film-applying mechanism and the edge-sealing plate are linked and move up and down synchronously. A demolding mechanism that detaches the packaging box from the film-applying mechanism is fixedly connected to the support frame, and the demolding mechanism is slidably connected to the film-applying mechanism. By placing the packaging box on the mold platform and applying the outer film to the outside of the packaging box through the extending or lifting film-applying mechanism, manual operation is effectively reduced, and efficiency is improved. Because the film-applying mechanism and the edge-sealing plate move up and down in tandem, the packaging box can be transferred to the edge-sealing plate during the lifting intervals, improving the continuous operation efficiency of each process.

[0006] Preferably, the model platform includes an upper platform and a lower platform, with the packaging box fitted onto the upper platform, and the edge of the lower platform closer to the upper platform being larger than the edge of the upper platform.

[0007] Preferably, the laminating mechanism includes a telescopic rod, an extrusion plate, a hinge seat, a gripper, a torsion spring, a roller, and a fixing block. One end of the telescopic rod is fixedly connected to a bracket, and the other end is fixedly connected to the extrusion plate. Hinges are fixedly connected around the extrusion plate. One end of the gripper is hinged to the hinge seat via a torsion spring, and the other end is fixedly connected to a fixing block. A roller is rotatably connected between two fixing blocks located on the same side of the extrusion plate. The gripper is shaped like a folded rod, offset from the center outwards from the extrusion plate. By incorporating the gripper and roller, the outer film of the packaging box is pressed firmly onto the packaging box by the roller during the lifting and lowering of the extrusion plate. Compared to manually applying the outer film to different sides of the packaging box separately, this improves efficiency and reduces labor intensity.

[0008] Preferably, a connecting rod is fixedly connected between the edge banding plate and the extrusion plate, and the middle part of the connecting rod is slidably connected to the bracket. A sliding rod is fixedly connected to the middle part of the connecting rod, and a slider is fixedly connected to the other end of the sliding rod. The bracket has a sliding groove, and the slider slides within the sliding groove.

[0009] Preferably, the demolding mechanism includes a connecting frame and abutting rods. The connecting frame is fixedly connected to the support, and several abutting rods are fixedly connected to the connecting frame and arranged perpendicular to the extrusion plate. The abutting rods pass through the extrusion plate and movably abut against the packaging box. By setting the abutting rods, the packaging box is pushed out from between the claws, facilitating the next process and reducing the probability of it being stuck by the claws and difficult to remove.

[0010] Preferably, the groove is a rectangular groove and the slider is a square block.

[0011] Compared with existing technologies, it has the following beneficial effects:

[0012] This utility model provides a packaging box edge-sealing machine. A model platform is set up on which a packaging box with an outer film pre-applied to its bottom surface is placed. A film-applying mechanism, which moves synchronously with the edge-sealing plate, applies the edge of the outer film to the side of the packaging box. Specifically, during the up-and-down movement of the telescopic rod, the claws and the rollers connected to the claws move up and down, applying the outer film to the side wall of the packaging box. During the lifting of the telescopic rod, the claws may lift the packaging box; therefore, a stop rod is provided to push the packaging box down when the claws rise. When the edge-sealing plate rises or falls, the telescopic rod rises or falls synchronously, and the slider connected to the connecting rod slides within a groove. The sliders in the groove and the groove are all square, reducing the probability of wobbling during sliding. Using the above technical solution, manual operation is effectively reduced, efficiency is improved, the continuous operation efficiency of each process is increased, the probability of deviation during film application is effectively reduced, and the time spent on rework is reduced.

Detailed Implementation

[0019] To better understand the structure, functional features, and advantages of this utility model, the preferred embodiments of this utility model are described in detail below with reference to the accompanying drawings:

[0020] Example:

[0021] like Figures 1 to 4As shown, this utility model provides a packaging box edge-sealing machine, including a machine base 1, a support 11, an edge-folding push rod 12 sliding around the packaging box, and an edge-sealing plate 13 extending and retracting on the support 11. The edge-folding push rod 12 is connected to a push plate, and the push plate is driven by the edge-folding push rod 12 to press the packaging box placed on the middle mold tightly around its perimeter. The edge-sealing plate 13 presses down from the top to press the top of the packaging box tightly, thereby not only sealing the edges of the packaging box, but also squeezing out air bubbles between the packaging box and the outer film. In the entire production process, the outer film is first placed on a conveyor belt. During the conveying process, the packaging box is placed on the outer film manually, with the bottom center corresponding to the center of the outer film. The conveyor belt continues to move forward, and the workers attach the outer film to the side walls of the packaging box. Then, the workers correct the deviation between the outer film and the packaging box to prevent large deviations. If deviations occur, the outer film needs to be torn off and reattached. Then, the packaging box is placed on the mold in the middle of the edge-folding push rod 12 for edge sealing and bubble suppression. A mold platform 2 is fixedly connected to the machine base 1 next to the folding push rod 12. A lifting and lowering film-applying mechanism 3 is fixedly connected to the top of the support 11 to apply the outer film to the packaging box. The film-applying mechanism 3 can vertically squeeze the outer film, reducing the probability of excessive deviation during film application. The film-applying mechanism 3 is linked to and synchronously raised and lowered with the edge-sealing plate 13. A demolding mechanism 5 is fixedly connected to the support 11 to disengage the packaging box from the film-applying mechanism 3. The demolding mechanism 5 is slidably connected to the film-applying mechanism 3. When the edge-sealing plate 13 descends, the film-applying mechanism 3 descends accordingly. After the film-applying mechanism 3 applies the outer film to the packaging box, the edge-sealing plate 13 rises, and the film-applying mechanism 3 rises accordingly, placing the packaged box with the applied outer film under the edge-sealing plate 13. At the same time, a new packaged box that needs to be filmed is placed under the film-applying mechanism 3. This operation is continuous and does not require an additional power mechanism.

[0022] As another embodiment, such as Figure 2 and Figure 3As shown, the laminating mechanism 3 of this application includes a telescopic rod 31, an extrusion plate 32, a hinge seat 33, a claw 34, a torsion spring 35, a roller 36, and a fixing block 37. One end of the telescopic rod 31 is fixedly connected to the bracket 11, and the other end of the telescopic rod 31 is fixedly connected to the extrusion plate 32. The extrusion plate 32 is fixedly connected to the four sides by the hinge seat 33. One end of the claw 34 is hinged to the hinge seat 33 through the torsion spring 35, and the other end of the claw 34 is fixedly connected to the fixing block 37. The roller 36 is rotatably connected between two fixing blocks 37 located on the same side of the extrusion plate 32. The claw 34 is a folded rod shape that is offset from the middle to the outside of the extrusion plate 32. The model platform 2 includes an upper platform body 21 and a lower platform body 22. The packaging box is fitted onto the upper platform body 21, and the edge of the lower platform body 22 near the upper platform body 21 is larger than the edge of the upper platform body 21. The upper platform 21 and lower platform 22 are integrally formed. The upper platform 21 is slightly smaller than the size of the packaging box. The connection between the upper platform 21 and the lower platform 22 is arc-shaped. This arc shape allows the claw 34 to expand outwards when it rises, thus holding less of the packaging box during the rising process, making it easier for the demolding mechanism 5 to push the packaging box out. The torsion spring 35 is located between the hinge seat 33 and the claw 34. When the claw 34 holds the packaging box, it rotates around the hinge seat 33, causing the torsion spring 35 to twist and deform. When it is released from the packaging box, the torsion spring 35 returns the claw 34 to its original position and simultaneously applies a certain force to the claw 34 to press the outer film onto the packaging box.

[0023] In use, the packaging box with the outer film attached to the bottom is placed on the mold table 2. When the telescopic rod 31 descends, the extrusion plate 32 descends. When the claw 34 on the extrusion plate 32 contacts the packaging box, it expands outward and, under the pressure provided by the torsion spring 35, adheres the outer film to the side wall of the packaging box. The claw 34 is located outside the lower platform 22. When the telescopic rod 31 rises, the claw 34 rises. When the arc of the connection between the upper platform 21 and the lower platform 22 is formed, it expands outward again. At this time, the claw 34 clamps the middle of the side wall of the packaging box, rather than the end, which facilitates the demolding mechanism 5 to demold.

[0024] As another embodiment, such as Figure 1 and Figure 4 As shown, a connecting rod 41 is fixedly connected between the edge banding plate 13 and the extrusion plate 32. The connecting rod 41 is a metal rod connecting the ends of the edge banding plate 13 and the extrusion plate 32, and its middle part is slidably connected to the bracket 11. A sliding rod 42 is fixedly connected to the middle part of the connecting rod 41, and a slider 43 is fixedly connected to the other end of the sliding rod 42. The bracket 11 has a groove 44, and the slider 43 slides within the groove 44. The groove 44 is a rectangular groove, and the slider 43 is a square block. When the edge banding plate 13 rises or falls, the connecting rod 41 rises and falls synchronously, driving the extrusion plate 32 to rise and fall. The slider 43 is driven to slide within the groove 44. Since the groove 44 is a rectangular groove and the slider 43 is a rectangular block, the lateral displacement is reduced during the sliding process, which can further improve the stability of the rise and fall of the edge banding plate 13 and the extrusion plate 32.

[0025] As another embodiment, such as Figure 1 and Figure 2 As shown, the demolding mechanism 5 of this application includes a connecting frame 51 and abutting rods 52. The connecting frame 51 is fixedly connected to the bracket 11, and several abutting rods 52 are fixedly connected to the connecting frame 51, which are perpendicular to the extrusion plate 32. The abutting rods 52 pass through the extrusion plate 32 and abut against the packaging box. Multiple abutting rods 52 can be provided; this solution uses four, which can improve stability during demolding. In use, the abutting rods 52 are fixed. During the descent of the extrusion plate 32, the claws 34 adhere the outer film to the surface of the packaging box. When the extrusion plate 32 rises, the pressure plate passes through the abutting rods 52, and the abutting rods 52 push the packaging box held by the rising claws 34 out between the claws 34, thus achieving demolding. This facilitates placing the packaging box between the folding push rods 12 for bubble pressing and folding.

[0026] The working principle of the packaging box edge-sealing machine disclosed in this application is as follows: During use, when the edge-sealing plate 13 descends, the film-coating mechanism 3 also descends. After the film-coating mechanism 3 applies the outer film to the packaging box, the edge-sealing plate 13 rises, and the film-coating mechanism 3 rises accordingly. The packaging box with the outer film applied is placed under the edge-sealing plate 13, and at the same time, a new packaging box that needs to be filmed is placed under the film-coating mechanism 3. This process continues continuously without the need for an additional power mechanism. Specifically, the packaging box with the outer film applied to the bottom is placed on the mold table 2. When the telescopic rod 31 descends, the extrusion plate 32 descends. The claws 34 on the extrusion plate 32 expand outward when they contact the packaging box, and under the pressure provided by the torsion spring 35, the outer film is applied to the side wall of the packaging box. The claws 34 are located outside the lower platform 22. When the telescopic rod 31 rises, the claws 34 rise, and the arc of the connection between the upper platform 21 and the lower platform 22 expands outward again. At this time, the claws 34 clamp the middle of the side wall of the packaging box, rather than the end, which facilitates demolding by the demolding mechanism 5. The abutment rod 52 is fixed. During the descent of the extrusion plate 32, the claw clamp 34 adheres the outer film to the surface of the packaging box. When the extrusion plate 32 rises, the pressure plate passes through the abutment rod 52. The abutment rod 52 pushes the packaging box held by the rising claw clamp 34 out between the claw clamps 34, realizing demolding. This makes it convenient to place the packaging box between the folding push rod 12 for bubble pressing and folding.

[0027] The above description is merely a preferred embodiment of this utility model and does not constitute any limitation on this utility model. Any person skilled in the art can make many possible variations and modifications to the technical solution of this utility model, or modify it into equivalent embodiments, without departing from the scope of the technical solution of this utility model. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technology of this utility model without departing from the scope of the technical solution of this utility model shall fall within the protection scope of this technical solution.
