Abstract
Description
Technical Field
[0001] This utility model relates to the field of packaging production technology, specifically to a double-layer cardboard cutting and splicing device. Background Technology
[0002] Double-layer cardboard is formed by gluing two pieces of cardboard together. In the actual production process, the two pieces of cardboard are first glued together. Then, a large piece of double-layer cardboard is longitudinally cut into several strips by a longitudinal cutting unit. Then, the strips are transversely cut into blocks by a transverse cutting unit, thus forming several pieces of double-layer cardboard for packaging.
[0003] Since this double-layer cardboard is mainly used in the preparation of mobile phone packaging boxes, its surface must be smooth and free of defects. In the existing technology, after several double-layer cardboards are cut into several pieces by the transverse cutting unit, they are usually received directly at the end of the conveying device. However, if the drop height of the double-layer cardboard is not controlled during the drop process, the falling double-layer cardboard may collide with the bottom double-layer cardboard, thus forming defects and affecting the yield. Utility Model Content
[0004] To address the shortcomings of existing technologies, this invention aims to provide a double-layer cardboard cutting and receiving device. By adopting this solution, the height of the inclined plate in the receiving chamber can be controlled, thereby greatly reducing the gravitational potential energy of the falling double-layer cardboard and allowing the double-layer cardboard to fall smoothly onto the inclined plate.
[0005] This utility model is achieved through the following technical solution:
[0006] A double-layer cardboard cutting and splicing device includes:
[0007] Inclined conveyor belt;
[0008] A receiving box is located at the lower end of the inclined conveyor belt outlet. The receiving box has an opening at the top and a first baffle inside, with the upper end of the first baffle extending out of the opening. A receiving cavity is formed between the first baffle and the inside of the receiving box.
[0009] The receiving chamber has a liftable base plate, and the base plate has an inclined plate. The inclined plate and the inclined conveyor belt are inclined in the same direction. The lower end of the inclined plate faces the first baffle, and the space between the inclined plate and the first baffle is used to place double-layer cardboard.
[0010] In contrast to existing technologies, where several double-layered cardboard pieces are cut into several pieces by a transverse cutting unit and then received directly at the end of the conveying device, if the drop height of the double-layered cardboard is not controlled during its fall, the falling cardboard may collide with the bottom double-layered cardboard, resulting in defects and affecting the yield. This invention provides a double-layered cardboard cutting and receiving device. By using this solution, the height of the inclined plate in the receiving chamber can be controlled, thereby greatly reducing the gravitational potential energy of the falling double-layered cardboard and allowing it to fall smoothly onto the inclined plate. The specific solution includes an inclined conveyor belt that receives several double-layered cardboard pieces cut by a transverse cutting unit. A receiving box is located at its outlet, with an opening at the top to facilitate the receipt of the double-layered cardboard. Inside the receiving box is a receiving cavity containing a liftable base plate. An inclined plate is mounted on the base plate. When the receiving box is used for receiving, the upper end of the inclined plate is flush with the upper surface of the inclined conveyor belt, with only a small gap between the upper end of the inclined plate and the lower end of the inclined conveyor belt. This allows the double-layered cardboard pieces on the inclined conveyor belt to slide directly onto the inclined plate. Driven by the following double-layered cardboard pieces, the preceding double-layered cardboard pieces eventually land on the inclined plate. Once one double-layered cardboard piece is on the inclined plate, the base plate can be lowered by one height to allow for the stacking of a second double-layered cardboard piece. In this way, several double-layered cardboard pieces can be stacked sequentially from bottom to top, thus completing the collection of the cardboard pieces. The first baffle has a smooth, flat surface and provides lateral support for the double-layered cardboard pieces. Therefore, by using the above method, the height of the inclined plate in the receiving chamber can be controlled, thereby greatly reducing the gravitational potential energy of the falling double-layer cardboard and allowing the double-layer cardboard to fall smoothly onto the inclined plate, thus completing the collection of several double-layer cardboards.
[0011] To adjust the inclination of the inclined plate to match the inclined conveyor belt, the lower end of the inclined plate is hinged to the base plate. The upper and lower sides of the inclined plate are hinged to the base plate via telescopic cylinders. Both ends of the telescopic cylinder are hinged to the inclined plate and the base plate respectively, and the rotation directions of the hinges are the same. In this design, the lower end of the inclined section is hinged via two connecting lugs and a rotating shaft. Similarly, the upper end is hinged to a telescopic cylinder, with both ends of the telescopic cylinder hinged. Thus, driven by the telescopic cylinder, the inclined section can adjust its own inclination to achieve parallelism with the inclined conveyor belt. In addition, when it is necessary to remove several double-layer cardboard sheets, the telescopic cylinder can be retracted to achieve a near-parallel state, thus facilitating the removal of the double-layer cardboard sheets.
[0012] To achieve the lifting and lowering of the base plate, the base plate is connected to the bottom of the receiving chamber via a lifting cylinder.
[0013] To control the height of the base plate based on the number of stacked first baffles and achieve automated lifting, the first baffle is equipped with a sensor for detecting the number of double-layer cardboard sheets on the inclined plate. The sensor can be a counting sensor or similar. The sensor transmits the detected signal to the control terminal, which then controls the lifting cylinder's raising and lowering.
[0014] Because friction may still occur when the cardboard contacts the first baffle during descent, causing the cardboard end to curl up, to prevent this, the first baffle is configured as a vertically arranged vertical conveyor belt with its conveying surface facing the inclined plate. The speed of the vertical conveyor belt is matched to the descent speed of the inclined plate. Specifically, by moving the conveying surface of the vertical conveyor belt downwards synchronously, it descends synchronously with the cardboard, thus eliminating friction.
[0015] To prevent several double-layered cardboard pieces from falling off the sides of the inclined conveyor belt, a guide assembly is also included. The guide assembly includes second baffles located on both sides of the inclined conveyor belt. The two second baffles are positioned between the two sides of the inclined conveyor belt and have a gap between them and the upper surface of the inclined conveyor belt. The height of the gap is less than the thickness of the double-layered cardboard. The second baffles on both sides effectively block several double-layered cardboard pieces, preventing them from falling off from the sides.
[0016] To guide and collect multiple double-layered cardboard sheets, several guide plates are sequentially and spaced apart between the two second baffles. These guide plates are parallel to the second baffles; the bottom of each guide plate is at the same height as the bottom of the second baffles; and a flow gap is formed between adjacent guide plates to allow individual double-layered cardboard sheets to pass through. In this design, when the double-layered cardboard sheets pass over the upper part of the guide plates, they are blocked and diverted, causing them to enter the flow gap. They then move downwards at an angle through the flow gap and finally fall onto the inclined plate.
[0017] To improve the flow guiding effect, the upper end of the flow guide plate is equipped with a flow guide head, the large diameter end of the flow guide head is connected to the flow guide plate, and the small diameter end of the flow guide head is round.
[0018] To further improve the flow guiding effect, the second baffle is equipped with a vibration motor. Driven by the vibration motor, the flow guiding head vibrates, thereby causing the double-layer cardboard stuck at the flow guiding head to enter the flow gap.
[0019] To collect the double-layer cardboard in each flow gap separately, so as to facilitate the individual stacking and collection of several double-layer cardboards, the receiving box has several receiving cavities along the width direction of the inclined conveyor belt, and each receiving cavity corresponds to a flow gap.
[0020] Compared with the prior art, this utility model has the following advantages and beneficial effects:
[0021] 1. This utility model provides a double-layer cardboard cutting and receiving device. By adopting this solution, the height of the inclined plate in the receiving chamber can be controlled, thereby greatly reducing the gravitational potential energy of the falling double-layer cardboard and enabling the double-layer cardboard to fall smoothly onto the inclined plate.
[0022] 2. This utility model provides a double-layer cardboard cutting and receiving device. Using this design, when several double-layer cardboards pass the upper end of the guide plate, they are blocked and diverted, causing the cardboards to enter the flow gap. They then move downwards at an angle through the flow gap and finally fall onto the inclined plate. The receiving box has several receiving cavities along the width of the inclined conveyor belt, each corresponding to a flow gap. This allows for the separate collection of double-layer cardboard in each flow gap, facilitating the individual stacking and collection of several double-layer cardboards. Attached Figure Description

[0034] Example:
[0035] This embodiment provides a double-layer cardboard cutting and splicing device, such as... Figures 1-5 As shown, it includes:
[0036] Inclined conveyor belt 1;
[0037] The receiving box 2 is located at the lower end of the inclined conveyor belt 1. The receiving box 2 has an opening at the top and a first baffle 4 inside. The upper end of the first baffle 4 extends out of the opening. A receiving cavity is formed between the first baffle 4 and the inside of the receiving box 2.
[0038] The receiving chamber has a liftable base plate 3, and the base plate 3 has an inclined plate 5. The inclined plate 5 and the inclined conveyor belt 1 are inclined in the same direction. The lower end of the inclined plate 5 faces the first baffle 4, and the space between the inclined plate 5 and the first baffle 4 is used to place double-layer cardboard.
[0039] Compared to existing technologies, where several double-layer cardboard pieces are cut into several pieces by a transverse cutting unit and then received directly at the end of the conveying device, if the drop height of the double-layer cardboard is not controlled during its fall, the falling double-layer cardboard may collide with the bottom double-layer cardboard, resulting in defects and affecting the yield. This invention provides a double-layer cardboard cutting and receiving device. By using this solution, the height of the inclined plate 5 in the receiving chamber can be controlled, thereby greatly reducing the gravitational potential energy of the falling double-layer cardboard and allowing it to fall smoothly onto the inclined plate 5. The specific solution includes an inclined conveyor belt 1, which receives several double-layer cardboard pieces cut by the transverse cutting unit. A receiving box 2 is located at its outlet, with an opening at the top to facilitate the receipt of the double-layer cardboard. The receiving box 2 has a receiving cavity inside, and a liftable base plate 3 within the cavity. An inclined plate 5 is mounted on the base plate 3. When the receiving box 2 is used for receiving, the upper end of the inclined plate 5 is flush with the upper surface of the inclined conveyor belt 1, and only a small gap needs to be left between the upper end of the inclined plate 5 and the lower end of the inclined conveyor belt 1. The gap is just right, so that the double-layer cardboard on the inclined conveyor belt 1 will slide directly onto the inclined plate 5. Under the pushing action of several subsequent double-layer cardboards, the preceding double-layer cardboard will eventually be placed on the inclined plate 5. Once one double-layer cardboard is on the inclined plate 5, the bottom plate 3 below can be lowered by one height, so that the second double-layer cardboard can be stacked. In this way, several double-layer cardboards can be stacked sequentially from bottom to top, thus completing the collection of several double-layer cardboards. The surface of the first baffle 4 is a smooth plane, which provides lateral support for several double-layer cardboards. Therefore, through the above scheme, the height of the inclined plate 5 in the receiving cavity can be controlled, thereby greatly reducing the gravitational potential energy of the falling double-layer cardboard, allowing the double-layer cardboard to fall smoothly onto the inclined plate 5, thus completing the collection of several double-layer cardboards.
[0040] To adjust the inclination of the inclined plate 5 to match the inclined conveyor belt 1, the lower end of the inclined plate 5 is hinged to the base plate 3, and the lower side of the upper end of the inclined plate 5 is hinged to the base plate 3 via a telescopic cylinder 6. Both ends of the telescopic cylinder 6 are respectively hinged to the inclined plate 5 and the base plate 3, and the rotation directions of the hinges are the same. In this design, the lower end of the inclined section is hinged via two connecting lugs and a rotating shaft. Similarly, the upper end is hinged to a telescopic cylinder 6, with both ends of the telescopic cylinder 6 hinged. Thus, driven by the telescopic cylinder 6, the inclined section can adjust its own inclination to achieve parallelism with the inclined conveyor belt 1. In addition, when it is necessary to remove several double-layer cardboard sheets, the telescopic cylinder 6 can be retracted to achieve a near-parallel state, thus facilitating the removal of the double-layer cardboard sheets.
[0041] To achieve the lifting and lowering of the base plate 3, the base plate 3 is connected to the bottom of the receiving chamber via a lifting cylinder 7.
[0042] To control the height of the base plate 3 based on the number of stacked first baffles 4 and achieve automated lifting, the first baffle 4 is equipped with a sensor for detecting the number of double-layer cardboard sheets on the inclined plate 5. The sensor can be a counting sensor or similar. The sensor transmits the detected signal to the control terminal, which then controls the lifting cylinder 7 to raise or lower.
[0043] Because friction may still occur when the cardboard contacts the first baffle 4 during descent, causing the cardboard end to curl up, to prevent this, the first baffle 4 is configured as a vertically arranged vertical conveyor belt, with its conveying surface facing the inclined plate 5. The speed of the vertical conveyor belt is matched to the descent speed of the inclined plate 5. Specifically, by moving the conveying surface of the vertical conveyor belt downwards synchronously, it descends synchronously with the cardboard, thus preventing friction.
[0044] To prevent several double-layered cardboard pieces from falling off the sides of the inclined conveyor belt 1, a guide assembly is also included. The guide assembly includes two second baffles 8 located on both sides of the inclined conveyor belt 1. The two second baffles 8 are positioned between the two sides of the inclined conveyor belt 1 and have a gap between them and the upper surface of the inclined conveyor belt 1. The height of the gap is less than the thickness of the double-layered cardboard. The second baffles 8 on both sides effectively block several double-layered cardboard pieces, preventing them from falling off from the sides.
[0045] To guide and collect several double-layered cardboard sheets, several guide plates 9 are sequentially and spaced apart between the two second baffles 8. The guide plates 9 are parallel to the second baffles 8; the bottom of the guide plates 9 is at the same height as the bottom of the second baffles 8; and a flow gap is formed between adjacent guide plates 9 to allow a single double-layered cardboard sheet to pass through. In this design, when several double-layered cardboard sheets pass over the upper end of the guide plates 9, they are blocked and diverted, causing the double-layered cardboard sheets to enter the flow gap, move downwards at an angle through the flow gap, and finally fall onto the inclined plate 5.
[0046] To improve the flow guiding effect, the upper end of the flow guide plate 9 is equipped with a flow guide head 901. The large diameter end of the flow guide head 901 is connected to the flow guide plate 9, and the small diameter end of the flow guide head 901 is round.
[0047] To further improve the flow guiding effect, the second baffle 8 is equipped with a vibration motor 10. Driven by the vibration motor 10, the flow guiding head 901 will vibrate, thereby causing the double-layer cardboard stuck at the flow guiding head 901 to enter the flow gap.
[0048] In order to collect the double-layer cardboard in each flow gap separately, so as to facilitate the individual stacking and collection of several double-layer cardboards, the receiving box 2 has several receiving cavities along the width direction of the inclined conveyor belt 1, and each receiving cavity corresponds to a flow gap.
[0049] Working Principle: In operation, the inclined conveyor belt 1 receives several double-layer cardboard pieces cut by the transverse cutting unit. As these double-layer cardboard pieces pass the upper end of the guide plate 9, they are blocked and diverted by the guide head 901, causing them to enter the flow gap and move downwards at an angle. Driven by the vibration motor 10, the guide head 901 vibrates, causing the double-layer cardboard pieces stuck at the guide head 901 to enter the flow gap. The receiving box 2 has several receiving cavities along the width of the inclined conveyor belt 1, each corresponding to a flow gap, collecting the double-layer cardboard pieces from each flow gap separately.
[0050] The double-layer cardboard on the inclined conveyor belt 1 will gradually slide onto the inclined plate 5. Under the pushing action of several double-layer cardboards behind, the double-layer cardboard in front will eventually be located on the inclined plate 5. When a double-layer cardboard is located on the inclined plate 5, the counting sensor detects the change in quantity and controls the bottom plate 3 below to descend by a height, so that the second double-layer cardboard can be stacked. In this way, several double-layer cardboards can be stacked from bottom to top, thereby completing the collection of several double-layer cardboards.
[0051] The double-layer cardboard cutting and receiving device provided by the above solution can control the height of the inclined plate 5 in the receiving chamber, thereby greatly reducing the gravitational potential energy of the falling double-layer cardboard and allowing it to fall smoothly onto the inclined plate 5. Furthermore, when several double-layer cardboards pass the upper end of the guide plate 9, they are blocked and diverted, causing them to enter the flow gap and move downwards at an angle through the flow gap, eventually falling onto the inclined plate 5. The receiving box 2 has several receiving chambers along the width of the inclined conveyor belt 1, each corresponding to a flow gap, enabling separate collection of double-layer cardboard in each flow gap, facilitating the individual stacking and collection of several double-layer cardboards.
[0052] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
