Description

Technical Field

[0001] This utility model relates to the field of folding equipment technology, specifically to a folding device for a blister packaging box. Background Technology

[0002] In the production process of blister packaging boxes, the folding process plays a decisive role in the overall quality and appearance of the packaging. The three-sided folding machine, as a key piece of equipment for folding blister packaging boxes, utilizes the principle of thermoforming and re-forming to efficiently and quickly fold the three sides of the packaging box. This equipment is widely used in the packaging industry, helping to improve production efficiency and ensuring that blister packaging boxes achieve the desired packaging effect.

[0003] Three-sided folding machines typically consist of a frame and worktable, a folding mechanism, and a control system. During folding, the packaging box is placed directly on top of the frame. However, in existing technologies, the frame lacks a corresponding positioning mechanism, and the placement of the blister packaging box relies entirely on the worker's experience. For example, utility model patent application CN202220777400.3 discloses an automatic folding device for blister packaging box production. This device includes a base with four rectangular grooves on its top outer wall. Electric telescopic rods are fixed to the bottom inner walls of the grooves, and the tops of the four electric telescopic rods are fixed to the same mounting plate. The top outer wall of the mounting plate is fixed with two symmetrically distributed first electric slide rails, and the top outer walls of the sliding parts of the two first electric slide rails are fixed with the same mounting plate. The positioning component of this utility model can hold the packaging box in place, preventing it from shifting during the folding process and improving the success rate of folding. The first electric slide rail can move the placement plate, which can be used in conjunction with the folding component for folding and also facilitates the placement and retrieval of the packaging box. Multiple support rollers can increase the stability of the placement plate during movement, and the electric telescopic rod can raise the height of the placement plate, which helps to fold the packaging box in conjunction with the folding component.

[0004] Although the device can prevent displacement during the folding process, when workers place the blister packaging boxes, there is no positioning mechanism on the base. This makes it easy for workers to place the boxes crookedly, which will seriously affect the subsequent folding quality. Therefore, we propose a folding device for blister packaging boxes. Utility Model Content

[0005] To solve the above problems, this utility model provides a folding device for blister packaging boxes.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A folding device for a blister packaging box, comprising:

[0008] Base;

[0009] Three folding sections are used for folding the three sides of the blister packaging box and are respectively installed on the top left, right and front sides of the base; including a fixing plate fixed to the base, and two electric cylinders are installed on the outer wall of the fixing plate, with a folding pressure block fixed between the piston rods of the two electric cylinders;

[0010] The support plate is installed above the base and fixed to the base by a support block;

[0011] The blister pack is placed horizontally on top of the tray;

[0012] The positioning part, used to limit the position of the blister packaging box on the top of the tray, is installed above the base; it includes two symmetrical side plates, a guide groove is opened at the center of the outer wall of the side plate, and a sliding groove is opened above the guide groove; a slider is slidably installed at the bottom of the sliding groove, and a toothed block is fixed at the bottom of the slider; a connecting rod is fixed at the top of the slider, the connecting rod passes through the top of the side plate and is slidably connected to the side plate, and a spring is sleeved on the outside of the connecting rod;

[0013] A first positioning plate is provided between the two side plates. One side wall of the first positioning plate abuts against the left and right outer walls of the blister packaging box. A guide block that is slidably connected to the guide groove is fixed on the other side wall of the first positioning plate. Multiple toothed grooves are opened on the top of the guide block, and the toothed block meshes with the toothed grooves.

[0014] A second, adjustable positioning plate is provided on the rear side of the first positioning plate to abut against the rear end of the blister packaging box.

[0015] Furthermore, the folding block is fixedly connected to the end of the piston rod of the electric cylinder by bolts, and the horizontal height of the top of the folding block is lower than the horizontal height of the bottom of the support plate;

[0016] In this setting, the design ensures that there is no interference with the tray during the folding process, making the folding action smoother.

[0017] Furthermore, two guide plates are fixed to the two opposite ends of the two first positioning plates, and through slots are provided at both ends of the outer wall of the side plates, with the guide plates slidably connected to the corresponding through slots.

[0018] Furthermore, a limiting rod is fixed inside the groove, and a limiting groove is opened at the top of the guide plate. The limiting rod passes through the limiting groove and is slidably connected to the limiting groove.

[0019] In these two settings, the guide plate and the limiting rod effectively restrict the movement direction of the first positioning plate, enhancing its stability during the positioning process and preventing deviation.

[0020] Furthermore, a fixing block is coaxially keyed to the top of the connecting rod, and a pull ring is coaxially keyed to the top of the fixing block;

[0021] In this configuration, the slider and toothed block can be easily adjusted via a pull ring, which in turn facilitates the adjustment of the first positioning plate.

[0022] Furthermore, a threaded rod is rotatably mounted on the rear end of the first positioning plate, and the threaded rod passes through the second positioning plate and is threadedly connected to the second positioning plate.

[0023] Furthermore, a support plate is fixed at one end of the second positioning plate, and a guide sleeve is fixedly connected to the rear end of the outer wall of the first positioning plate by bolts. The support plate passes through the guide sleeve and is slidably connected to the guide sleeve.

[0024] Furthermore, an adjusting head is coaxially keyed to the rear end of the threaded rod, and the cross-sectional shape of the adjusting head is a regular hexagon.

[0025] Of these three settings, the position of the second positioning plate can be easily adjusted by rotating the threaded rod, so that the second positioning plate can be tightly pressed against the rear end of the blister packaging box, adapting to packaging boxes of different sizes and improving positioning flexibility and versatility.

[0026] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0027] 1. The two side plates, slider, toothed block, first positioning plate, and guide block of the positioning part cooperate with each other. The slider drives the toothed block to slide in the groove. Through the meshing of the toothed block and the groove, the position of the first positioning plate can be quickly adjusted to accurately position the blister packaging box in the left and right directions. An adjustable second positioning plate is set at the rear end of the first positioning plate. It is threadedly connected to the second positioning plate through a threaded rod. Rotating the threaded rod can adjust the position of the second positioning plate to achieve tight positioning of the rear end of the blister packaging box. This design can effectively avoid the misalignment of the blister packaging box when folding the edge, thereby improving the subsequent folding quality.

[0028] 2. The folding section is designed with a fixed plate, electric cylinder and folding pressure block. The electric cylinder drives the folding pressure block to perform the folding action, and the power is stable. The top of the folding pressure block is lower than the bottom of the support plate, which ensures that it will not interfere with the support plate during the folding process and ensures that the folding action is carried out smoothly.

[0041] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0042] This embodiment provides a technical solution:

[0043] Please see Figures 1-2 As shown, a folding device for a blister packaging box includes a base 1; three folding sections 2 for folding the three sides of the blister packaging box and respectively installed on the top left, right and front sides of the base 1; a fixing plate 20 fixed to the base 1, with two electric cylinders 21 installed on the outer wall of the fixing plate 20, and a folding pressure block 22 fixed between the piston rod ends of the two electric cylinders 21; a support plate 3 installed above the base 1 and fixed to the base 1 by a support block, the support block being fixedly connected to the base 1 and the support plate 3 by bolts; and a blister packaging box 4 placed horizontally on top of the support plate 3.

[0044] The above configuration allows for easy folding of three sides of the blister packaging box by moving the folding block 22.

[0045] In this embodiment, the folding pressure block 22 is fixedly connected to the end of the piston rod of the electric cylinder 21 by bolts, and the top of the folding pressure block 22 is lower than the bottom of the support plate 3. The folding pressure block 22 is fixedly connected to the end of the piston rod of the electric cylinder 21 by bolts, which facilitates disassembly and replacement to meet different folding requirements; the top of the folding pressure block 22 is lower than the bottom of the support plate 3 to ensure that it will not interfere with the support plate 3 during the folding process, making the folding action smoother and ensuring the stability of the folding operation and the safety of equipment operation.

[0046] Please see Figures 1-6 As shown, the positioning part 5, used to limit the position of the blister packaging box 4 on the top of the tray 3, is installed above the base 1; it includes two symmetrical side plates 50, a guide groove 502 is formed at the center of the outer wall of the side plate 50, and a sliding groove 503 is formed above the guide groove 502; a slider 51 is slidably installed at the bottom of the sliding groove 503, and a toothed block 510 is fixed at the bottom of the slider 51; a connecting rod 52 is fixed at the top of the slider 51, the slider 51 and the toothed block 510 are integrally formed, and the slider 51 and the connecting rod 52 are fixedly connected by bolts, the connecting rod 52 passes through the top of the side plate 50 and is slidably connected to the side plate 50, and the connecting rod 52 is externally sleeved. A spring 53 is provided; a first positioning plate 56 is provided between the two side plates 50. One side wall of the first positioning plate 56 abuts against the left and right outer walls of the blister packaging box 4, and a guide block 560 is fixed to the other side wall of the first positioning plate 56 and slidably connected to the guide groove 502. The top of the guide block 560 has multiple toothed grooves 5600, and the toothed block 510 meshes with the toothed grooves 5600. A second positioning plate 57 is provided on the rear side of the first positioning plate 56 for abutting against the rear end of the blister packaging box 4 and is adjustable. A threaded rod 58 is rotatably installed on the rear end of the first positioning plate 56. The threaded rod 58 passes through the second positioning plate 57 and is threadedly connected to the second positioning plate 57. By rotating the threaded rod 58, the position of the second positioning plate 57 can be easily adjusted using the thread transmission principle, so that it abuts tightly against the rear end of the blister packaging box, adapting to packaging boxes of different sizes and improving positioning flexibility and versatility.

[0047] Through the above-mentioned setup, the positioning unit 5 uses the side plate 50, slider 51, first positioning plate 56 and other structures to accurately position the packaging box, achieve efficient three-sided folding, solve the problems of inaccurate positioning and poor folding quality of existing equipment, and improve production efficiency and product quality.

[0048] Please see Figure 3 and Figure 6As shown, in this embodiment, two guide plates 561 are fixed to each of the two opposite end faces of the two first positioning plates 56. Slots 500 are provided at both ends of the outer wall of the side plate 50, and the guide plates 561 are slidably connected to the corresponding slots 500. This structural design effectively restricts the movement direction of the first positioning plates 56, enhances their stability during positioning, avoids deviation, and thus ensures the positioning accuracy of the blister packaging box. A limiting rod 501 is fixed inside the slot 500, and a limiting groove 5610 is provided at the top of the guide plate 561. The limiting rod 501 passes through the limiting groove 5610 and is slidably connected to it. This structural design in this embodiment restricts the movement direction of the first positioning plates 56, ensuring the movement stability of the first positioning plates 56.

[0049] Please see Figure 4 As shown, in this embodiment, a fixing block 54 is coaxially keyed to the top of the connecting rod 52, and a pull ring 55 is coaxially keyed to the top of the fixing block 54. The operator can easily pull the connecting rod 52 through the pull ring 55, which will drive the slider 51 and the toothed block 510 to move, thereby realizing the rapid adjustment of the position of the first positioning plate 56. The operation is convenient and labor-saving, and the positioning efficiency is improved.

[0050] Please see Figure 6 As shown, a support plate 570 is fixed to one end of the second positioning plate 57, and a guide sleeve 562 is bolted to the rear end of the outer wall of the first positioning plate 56. The support plate 570 passes through the guide sleeve 562 and is slidably connected to it. This structure provides guidance and support when adjusting the position of the second positioning plate 57, ensuring smooth movement of the second positioning plate 57, improving positioning reliability, and ensuring folding accuracy. An adjusting head is coaxially keyed to the rear end of the threaded rod 58, and the adjusting head has a regular hexagonal cross-section. This design facilitates rapid rotation of the threaded rod 58, making the adjustment process easier and more convenient.

[0051] It should be added that the folding mechanism of the three-sided folding machine mainly consists of three-sided heating plates and folding components. When processing blister packaging boxes, a high-precision electric push rod or pneumatic cylinder drives the three-sided heating plates to move down synchronously. The ceramic coating on the surface of the heating plate is high-temperature resistant, corrosion resistant, and has uniform heat conduction. The internal high-efficiency heating wire, combined with the temperature control system, can rapidly heat up to 150℃-250℃, precisely softening the edges of the packaging box, ensuring the plasticity of the material while avoiding excessive melting and deformation. After the material softens, the folding components are immediately applied (this is in the prior art and will not be described in detail here); while the multiple folding pressure blocks 22 set in this embodiment are used to apply pressure to the edges of the packaging box, thereby precisely bending the softened material into shape to complete the folding operation.

[0052] It is worth noting that the electric cylinder 21 involved in this embodiment is a conventional technology and will not be described in detail here.

[0053] In practical use, the user first places the blister packaging box 4 on top of the tray 3. The operator pulls the pull ring 55, which moves the connecting rod 52 upward, causing the slider 51 to slide in the groove 503. The toothed block 510 at the bottom of the slider 51 disengages from the toothed groove 5600. Then, the user adjusts the position of the first positioning plate 56 so that its side wall fits against the left and right outer walls of the blister packaging box 4. At this time, the pull ring 55 is released, and under the action of the spring 53, the toothed block 510 re-engages with the toothed groove 5600 and fixes the first positioning plate 56. Then, the user rotates the threaded rod 58, and through the threaded transmission, moves the second positioning plate 57 along the sliding direction of the support plate 570 and the guide sleeve 562 until it presses against the rear end of the blister packaging box 4, and the packaging box is positioned.

[0054] After the blister packaging box 4 is positioned, the user turns on the power of the electric cylinder 21. The electric cylinder 21 drives the piston rod to extend, which in turn moves the folding edge pressing block 22 to the three sides of the blister packaging box 4. Since the top horizontal height of the folding edge pressing block 22 is lower than the bottom horizontal height of the tray 3, it can avoid interference with the tray 3. Under the action of the piston rod of the electric cylinder 21, the folding edge pressing block 22 bends the three sides of the packaging box to the set angle, thus completing the folding operation.

[0055] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
