Description

Technical Field

[0001] This utility model belongs to the field of irregular-shaped packaging box technology, and in particular relates to an irregular-shaped packaging box forming equipment. Background Technology

[0002] In the packaging sector for high-value-added products such as cosmetics, electronics, gifts, food, and medical devices, the demand for irregularly shaped packaging boxes (i.e., non-standard rectangles, boxes with complex three-dimensional curved surfaces, multiple steps, and high depth-to-depth ratios) is increasing. This type of packaging not only better protects the contents, but its unique appearance is also key to enhancing brand image and consumer experience.

[0003] Vacuum forming is one of the processes for forming irregularly shaped packaging boxes. Its basic principle is to heat thermoplastic sheets to a softened state, then press them into shape using a mold, and finally cool and solidify them to form the desired product. However, in the current technology, there is waste material at the edges after the packaging box is formed, which requires additional cutting equipment. Material transfer relies on manual operation, which is time-consuming and affects the overall processing efficiency.

[0004] Therefore, we have proposed a special-shaped packaging box forming equipment. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a non-standard packaging box forming device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An irregularly shaped packaging box forming device, comprising: The base has two parallel lower supports fixedly mounted on its surface. A C-shaped guide plate is fixedly mounted on the top of the lower supports. Two rows of conveyor shafts rotatably pass through the inner wall of one side of the guide plate. The upper support is mounted on the top of the two lower supports. The first lifting seat is installed on the inner side of the upper support. The bottom of the first lifting seat is fixed with an upper mold, a cutter and multiple infrared sensors. The upper mold has a cooling channel inside, and both ends of the cooling channel are fixedly connected to connecting pipes. The second lifting seat is installed on the surface of the base. The surface of the second lifting seat is fixed with a lower mold and a heating plate. The bottom of the lower mold has a clearance groove, and the heating plate is located in the clearance groove. The surface of the second lifting seat has a cutting port. The drive mechanism, located on one side of the lower support, is used to provide drive for the conveyor shaft; The first adjustment mechanism is located at the top of the upper support and is used to adjust the height of the first lifting seat. The second adjustment mechanism is located on the surface of the base and is used to adjust the height of the second lifting seat.

[0007] In one possible design, the drive mechanism includes a cover fixed to one side of the lower support and two motors. The output shafts of the two motors are respectively fixed to one of the two rows of conveyor shafts. Two adjacent conveyor shafts in the same row are connected by a sprocket and chain drive. The motors, sprockets and chains are all located inside the cover.

[0008] In one possible design, the first adjustment mechanism includes two first hydraulic cylinders fixed to the top of the upper support and a plurality of first guide rods fixed to the top of the first lifting seat. One end of the piston rod of the first hydraulic cylinder passes through the upper support and is fixed to the top of the first lifting seat, and the first guide rod slides through the upper support.

[0009] In one possible design, the second adjustment mechanism includes two second hydraulic cylinders and four second guide rods fixed to the surface of the base. One end of the piston rod of the second hydraulic cylinder is fixed to the bottom of the second lifting seat, and the second lifting seat is slidably sleeved on the outer wall of the second guide rods.

[0010] In one possible design, two symmetrically arranged guide blocks are fixed to one inner wall of the guide plate, and a guide surface is provided on one side of the guide blocks.

[0011] In one possible design, the surface of the base is fixed with an inclined unloading plate, which is located below the cutting opening.

[0012] In this application, during use, the connecting pipe and cooling equipment are connected, the motor is started to drive the conveyor shaft to rotate, and then thermoplastic plastic is put into the guide block. The conveyor shaft clamps and conveys the plastic. When the infrared sensor detects the plastic, it sends a signal to the control terminal, which then shuts off the motor to stop the conveyor shaft. Then, the second hydraulic cylinder is started to drive the second lifting seat to rise a specified distance, so that the upper mold is in contact with the bottom of the plastic. At the same time, the heating plate is started to heat for a specified time to soften the plastic. Then, the first hydraulic cylinder is started to drive the first lifting seat to fall, and the lower mold and the upper mold are combined to shape the softened plastic. Then, coolant is injected through the cooling channel to cool and shape the plastic. Then, the first lifting seat and the upper mold are reset, and the second lifting seat and the lower mold are lowered. Then, the conveyor shaft is driven to move the shaped plastic to below the cutter. After the infrared sensor detects the shaped plastic, the motor is shut off again, and then the second lifting seat is driven to rise, so that the cutting port is in contact with the bottom of the plastic. The first lifting seat and the cutter are driven to fall and cut the shaped plastic, so that the shaped plastic falls from the cutting port and is discharged from the unloading plate. The remaining waste continues to be conveyed by the conveyor shaft and falls into the pre-prepared collection device.

[0013] Beneficial effects: The irregular packaging box forming equipment described in this utility model, through the setting of upper mold, lower mold and cutter and other structures, can quickly cut the edge waste after the packaging box is formed, saving material transfer time, saving the labor of workers and improving efficiency; In this utility model, the irregularly shaped packaging box forming equipment can separate the cut packaging boxes and waste materials through the setting of structures such as unloading plate and conveyor shaft, which facilitates the sorting and processing by the staff.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0018] In the description of this utility model, it should be understood that the terms "opening", "upper", "middle", "length", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0019] To keep the following description of the embodiments of this utility model clear and concise, detailed descriptions of known functions and known components are omitted.

[0020] In one embodiment: Refer to Figures 1-4 A forming device includes: a base 1, on which two lower supports 2 are bolted to its surface. The two lower supports 2 are parallel to each other and spaced apart along the length of the base 1. A C-shaped guide plate 4 is welded to the top of each lower support 2. The two guide plates 4 are symmetrically arranged to form a material conveying and guiding space. Two rows of conveying shafts 5 are rotatably passed through the inner wall of the guide plate 4 facing the conveying path. The two rows of conveying shafts 5 are vertically aligned, and the outer wall of the shafts is in contact with the material to be processed. The material is conveyed by rotation.

[0021] The upper support 3 spans the tops of the two lower supports 2, with its two ends welded and fixed to the tops of the two lower supports 2 respectively, forming a gate-shaped structure. The bottom of the first lifting seat 8 is fixed with an upper mold 9, a cutter 11, and multiple infrared sensors 12 via screws. The cavity of the upper mold 9 matches the shape of the irregularly shaped packaging box to be formed, and its inner side is pre-processed with cooling channels arranged in a serpentine pattern to expand the cooling area. Connecting pipes 10 are welded to both ends of the channels, and the other end of the connecting pipes 10 can be connected to an external chiller or cooling water pump for introducing coolant. The blade of the cutter 11 faces downwards, corresponding to the cutting port 18 below. The infrared sensors 12 are used to detect whether the conveyed material has reached the predetermined forming position.

[0022] The second lifting seat 15 is mounted on the surface of the base 1. A lower mold 16 and a heating plate 17 are bolted to the surface of the second lifting seat 15. The cavity of the lower mold 16 mates with the cavity of the upper mold 9. A clearance groove is provided at the bottom of the lower mold 16, into which the heating plate 17 is embedded. The top surface of the heating plate 17 is flush with the bottom surface of the cavity of the lower mold 16. The heating plate 17 can be electrically heated and connected to an external power source via wires. During operation, it generates heat to soften the material. A cutting opening 18 is also provided on the surface of the second lifting seat 15. The cutting opening 18 corresponds to the cutter 11, and its size is slightly larger than the cutter 11, facilitating the cutter 11 to extend and complete the cutting.

[0023] The drive mechanism is installed on one side of the lower support 2 and is used to drive the conveyor shaft 5 to rotate. Specifically, the drive mechanism includes a cover 6 and two motors. The cover 6 is fixed to the side of the lower support 2 with screws, protecting the internal transmission components. The two motors are fixed inside the cover 6. The output shaft of one motor is welded to one end of the upper conveyor shaft 5, and the output shaft of the other motor is welded to one end of the lower conveyor shaft 5. The conveyor shafts 5 in the same row are connected by sprockets and chains. When the motor starts, the output shaft drives the corresponding conveyor shaft 5 to rotate. Through the transmission of sprockets and chains, all conveyor shafts 5 in the same row rotate synchronously, thereby driving the material forward.

[0024] The first adjustment mechanism is located at the top of the upper support 3 and is used to adjust the height of the first lifting seat 8. This mechanism includes two first hydraulic cylinders 14 and multiple first guide rods 13. The two first hydraulic cylinders 14 are fixed to the top of the upper support 3 via flanges, and their piston rods extend vertically downwards through the top plate of the upper support 3 and are fixed to the top of the first lifting seat 8. The bottom end of the first guide rod 13 is welded to the top of the first lifting seat 8, and its top end slides through the top plate of the upper support 3. When the piston rods of the first hydraulic cylinders 14 extend or retract, they drive the first lifting seat 8 to move up and down along the sliding groove on the inner side of the upper support 3. The first guide rods 13 move synchronously with the first lifting seat 8, ensuring that there is no deviation or shaking during the movement and improving stability.

[0025] The second adjustment mechanism is installed on the surface of the base 1 and is used to adjust the height of the second lifting seat 15. This mechanism includes two second hydraulic cylinders 20 and four second guide rods 19. The two second hydraulic cylinders 20 are bolted to the surface of the base 1 and located below the second lifting seat 15, with their piston rods vertically upward and fixed to the bottom of the second lifting seat 15. The four second guide rods 19 are rectangularly distributed, with their bottom ends welded to the surface of the base 1 and their top ends extending upward. Through holes are machined at the four corners of the second lifting seat 15, which slides onto the outer wall of the second guide rods 19. When the piston rods of the second hydraulic cylinders 20 extend or retract, they drive the second lifting seat 15 to move up and down along the second guide rods 19, thereby adjusting the height of the lower mold 16 and the heating plate 17, and cooperating with the upper mold 9 to complete the mold closing action.

[0026] This application can be used in the field of irregularly shaped packaging boxes, or in other fields applicable to this application.

[0027] In another embodiment: a non-shaped packaging box forming device, which is applied to the field of non-shaped packaging boxes; In one aspect of this embodiment, two guide blocks 7 are fixed to the inner wall of one side of the guide plate 4 by screws. The two guide blocks 7 are symmetrically distributed on both sides of the conveying path, and the distance between them is slightly larger than the width of the material to be processed. During the material conveying process, the material passes between the two guide blocks 7, which can prevent the material from shifting left and right during the conveying process and ensure that the material accurately enters the forming area between the upper mold 9 and the lower mold 16.

[0028] A discharge plate 21 is also welded to the surface of the base 1. The discharge plate 21 is set at an angle, with its high end located directly below the cutting port 18 and its low end facing the outside of the equipment. When the cutter 11 cuts the formed packaging box off the material, the packaging box will fall from the cutting port 18 onto the discharge plate 21 and then slide out of the equipment along the inclined plate surface for easy collection by the operator.

[0029] Workflow: The material to be processed is first placed between the conveyor shafts 5. The motor of the drive mechanism is started, and the conveyor shafts 5 rotate, driving the material forward. After being guided by the guide block 7, it gradually approaches the upper mold 9 and the lower mold 16. When the front end of the material moves to the detection area of ​​the infrared sensor 12, the infrared sensor 12 detects that the material is in place and sends a signal to the control unit (such as a PLC controller). The control unit pauses the drive mechanism, and the material is stopped from being conveyed. Subsequently, the piston rod of the first hydraulic cylinder 14 of the first adjusting mechanism extends, driving the first lifting seat 8 to move downward. At the same time, the piston rod of the second hydraulic cylinder 20 of the second adjusting mechanism extends, driving the second lifting seat 15 to move upward, so that the upper mold 9 and the lower mold 16 approach each other and close, clamping the material in the middle. At this time, the heating plate 17 is energized and heats up the part of the material in contact with the lower mold 16, softening the material for easy shaping. Under the extrusion of the upper and lower molds, the preliminary shape of the irregularly shaped packaging box is formed.

[0030] After the molding process lasts for approximately 5-10 seconds, coolant (such as cooling water) is introduced into the cooling channel of the upper mold 9 through the connecting pipe 10. The coolant flows within the channel, absorbing the heat of the material and rapidly cooling and solidifying the softened material, which takes approximately 3-5 seconds. After solidification, the piston rods of the first hydraulic cylinder 14 and the second hydraulic cylinder 20 retract, causing the first lifting seat 8 and the second lifting seat 15 to reset, separating the upper mold 9 and the lower mold 16. Next, the first lifting seat 8 moves downward again under the drive of the first hydraulic cylinder 14, causing the cutter 11 to contact and cut the material. The resulting packaging box falls from the cutting port 18 and slides out along the unloading plate 21. After cutting, the first lifting seat 8 resets, the drive mechanism restarts, and the conveyor shaft 5 continues to convey the remaining material, entering the next molding cycle.
