Description

Technical Field

[0001] This invention relates to the field of packaging equipment, and more particularly to a box forming device. Background Technology

[0002] Cardboard boxes are the most widely used packaging product, consistently ranking first in usage among all packaging materials. Corrugated cardboard boxes, with their superior performance and ease of processing, have gradually replaced wooden crates and other transport packaging containers, becoming the mainstay of transport packaging. To reduce space usage, cardboard boxes are typically folded and pressed together on both sides, stacked as flat sheets. When using these boxes, workers must grasp the flat sheets and unfold them into square boxes before use. Manually unfolding the boxes is inefficient.

[0003] This invention was developed to address the shortcomings of existing technologies. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a box forming device.

[0005] This invention can be achieved through the following technical solutions:

[0006] This invention discloses a box-retrieving and forming device, comprising a box-retrieving slide table mounted on a frame and slidably connected to the frame, a box-retrieving synchronous belt mounted on the frame, the box-retrieving synchronous belt being driven to rotate by a box-retrieving motor, the box-retrieving synchronous belt being fixed to the box-retrieving slide table, a box-retrieving rotary motor being fixed to the box-retrieving slide table, a box-retrieving rotary shaft being fixed to the output end of the box-retrieving rotary motor, a box-retrieving connecting plate being fixed to the box-retrieving rotary shaft, a box-retrieving fixing plate being fixed to the box-retrieving connecting plate, a box-retrieving positioning plate being rotatably connected to the box-retrieving fixing plate at the end of the box-retrieving fixing plate, a box-retrieving forming cylinder being fixed to the box-retrieving connecting plate, the piston rod end of the box-retrieving forming cylinder being connected to the box-retrieving positioning plate via a box-retrieving push rod, multiple box-retrieving cylinders being fixed to both the box-retrieving positioning plate and the box-retrieving fixing plate, and multiple suction cups being fixed to each box-retrieving cylinder.

[0007] Preferably, a box-retrieving support rod is also fixed on the box-retrieving slide. The box-retrieving support rod supports the box-retrieving fixing plate.

[0008] Preferably, the frame is further provided with a carton conveying device, which includes carton limiting plates on both sides of the frame. Carton conveying shafts are symmetrically arranged on both sides of the frame, and carton pulleys are symmetrically fixed on both sides of each carton conveying shaft. Corresponding carton pulleys on the two carton conveying shafts are connected by a carton conveyor belt. Carton conveying cylinders are also symmetrically arranged on both sides of the frame. Both ends of one of the carton conveying shafts are connected to a carton conveying push plate via one-way bearings. The piston rod end of the carton conveying cylinder is connected to the corresponding carton conveying cylinder. The conveyor belt is connected to a push plate. A carton conveying support plate is also fixedly inclined on the frame at the end of the carton conveying support plate. Multiple carton sliders are also provided on the frame above the carton conveying support plate. A carton positioning block is fixed on the carton slider. A carton sliding rod is also fixed on the carton slider. The carton sliding rod passes through the frame at the corresponding position and is slidably connected to the frame. A carton spring is fixed between the carton slider and the frame. Carton positioning shafts are also symmetrically fixed on both sides of the frame. Each carton positioning shaft is provided with a carton positioning wheel that is rotatably connected to the carton positioning shaft. The boxes are evenly placed on the carton conveyor, with the bottom sides of each box resting on the conveyor belt. The top sides of the leftmost box are supported by positioning wheels. When a box needs to be moved for the suction cups to pick it up, the carton conveyor cylinder is activated. The piston rod on the cylinder extends and then retracts. Because both ends of the carton conveyor shaft are connected to the conveyor push plate via one-way bearings, the conveyor shaft does not rotate when the piston rod extends. When the piston rod retracts, the conveyor shaft rotates at a certain angle. When the carton conveyor shaft rotates, the carton conveyor belt rotates as well. The carton conveyor belt is evenly equipped with slots. As the carton conveyor belt rotates, it pushes the bottom of the packaging box to move. After the bottoms of multiple packaging boxes move, they separate from the carton conveyor belt. Due to the weight of the packaging box itself, the bottom of the packaging box slides onto the carton conveyor support plate for support, and the top of the packaging box separates from the carton positioning wheel. The sides of the packaging box are supported by multiple carton positioning blocks. When the carton forming device grabs the carton, the suction cup contacts the outermost packaging box on the carton conveyor support plate and grabs the packaging box.

[0009] Preferably, multiple carton positioning cylinders are also fixed on the frame above the carton conveying support plate, and a carton positioning plate is fixed to the end of the piston rod of each carton positioning cylinder. When the bottom of the packaging box slides to the position of the carton conveying support plate, the carton positioning cylinder is activated, the piston rod of the carton positioning cylinder extends, the carton positioning plate descends, and the carton positioning plate neatly stacks the packaging boxes on the carton conveying support plate to ensure accurate gripping by the suction cup.

[0010] Compared with existing technologies, the present invention has the following advantages:

[0011] This device can automatically pick up sheet-shaped packaging boxes and then unfold them into a square shape without manual operation, greatly improving production efficiency. Attached Figure Description

[0021] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings:

[0022] Example 1:

[0023] like Figures 1 to 7As shown, this embodiment discloses a box-retrieving and forming device, including a box-retrieving slide 703 mounted on and slidably connected to a frame 1. A box-retrieving synchronous belt 701 is also mounted on the frame 1. The box-retrieving synchronous belt 701 is driven to rotate by a box-retrieving motor 702. The box-retrieving synchronous belt 701 is fixed to the box-retrieving slide 703. A box-retrieving rotary motor 704 is fixed on the box-retrieving slide 703. A box-retrieving rotary shaft 705 is fixed to the output end of the box-retrieving rotary motor 704. A box-retrieving connecting plate 706 is fixed on the box-retrieving rotary shaft 705. A box-retrieving connecting plate 706 is also fixed with a box-retrieving fixing plate 707. At the end of the box-retrieving fixing plate 707, a box-retrieving positioning plate 712 is provided, which is rotatably connected to the box-retrieving fixing plate 707. A box-retrieving forming cylinder 710 is also fixed on the box-retrieving connecting plate 706. The piston rod end of the box-retrieving forming cylinder 710 is connected to the box-retrieving positioning plate 712 through a box-retrieving push rod 711. Multiple box-retrieving cylinders 709 are fixed on both the box-retrieving positioning plate 712 and the box-retrieving fixing plate 707. Multiple suction cups 708 are fixed on each of the box-retrieving cylinders 709. The bottom of the packaging box 15 is supported by the carton conveyor support plate 607. The box-picking motor 702 drives the box-picking timing belt 701 to rotate. When the box-picking timing belt 701 rotates, the box-picking slide 703 moves. After the box-picking slide 703 moves to the designated position, the box-picking fixing plate 707 and the box-picking positioning plate 712 move close to the packaging box 15 in a plane. After the box-picking fixing plate 707 moves to the designated position, the box-picking cylinder 709 on the box-picking fixing plate 707 and the box-picking positioning plate 712 is activated. The piston rod on the box-picking cylinder 709 extends, and the suction cup 708 moves. After the suction cup 708 is pressed tightly against the surface of the packaging box 15, the suction cup 708 is connected to a vacuum pump through an air pipe. The vacuum pump draws a vacuum at the position of the suction cup 708, creating a negative pressure at the position of the suction cup 708, and the packaging box 15 is attracted to the suction cup 708. On surface 8, the box-picking motor 702 drives the box-picking synchronous belt 701 to rotate again, and the box-picking slide 703 moves away from the carton conveying device 6. After the packaging box 15 is picked up by the suction cup 708, it is pulled out from the carton conveying device 6. After the packaging box 15 moves to the designated position, the box-picking forming cylinder 710 is started. The piston rod on the box-picking forming cylinder 710 extends, and the box-picking push rod 711 drives the box-picking positioning plate 712 to rotate. The box-picking positioning plate 712 forms a 90-degree angle with the box-picking fixing plate 707. The packaging box 15 deforms with the rotation of the box-picking positioning plate 712. The packaging box 15 unfolds into a diamond shape to form a packaging box 15 with open ends. The box-picking rotary motor 704 drives the box-picking rotary shaft 705 to rotate at a certain angle. After adjusting the packaging box 15 to a suitable angle, it is supplied to the product for boxing and packaging.

[0024] The frame 1 is also equipped with a carton conveying device 6, which includes carton limiting plates 601 on both sides of the frame 1. Carton conveying shafts 602 are symmetrically arranged on both sides of the frame 1, and carton pulleys 603 are symmetrically fixed on both sides of each shaft. Corresponding carton pulleys 603 on the two conveying shafts 602 are connected by a carton conveyor belt 604. Carton conveying cylinders 605 are also symmetrically arranged on both sides of the frame 1. Both ends of one of the conveying shafts 602 are connected to a carton conveying push plate 606 via one-way bearings. The piston rod end of the carton conveying cylinder 605 is connected to the corresponding carton conveying push plate 606. Next, a carton conveying support plate 607 is also fixed obliquely on the frame 1 at the end of the carton conveyor belt 604. Multiple carton sliders 608 are also provided on the frame 1 above the carton conveying support plate 607. A carton positioning block 611 is fixed on the carton slider 608. A carton sliding rod 609 is also fixed on the carton slider 608. The carton sliding rod 609 passes through the frame 1 at the corresponding position and is slidably connected to the frame 1. A carton spring 610 is fixed between the carton slider 608 and the frame 1. Carton positioning shafts 614 are also symmetrically fixed on both sides of the frame 1. Carton positioning wheels 615 are provided on the carton positioning shafts 614 and are rotatably connected to the carton positioning shafts 614. The packaging boxes 15 are evenly placed on the carton conveyor device 6, with the bottom sides of each box 15 resting on the carton conveyor belt 604. The top sides of the leftmost box 15 are supported by carton positioning wheels 615. When the packaging box 15 needs to be moved for the suction cup 708 to grasp, the carton conveying cylinder 605 is activated. The piston rod on the carton conveying cylinder 605 extends and then retracts. Since both ends of the carton conveying shaft 602 are connected to the carton conveying push plate 606 via one-way bearings, the carton conveying shaft 602 does not rotate when the piston rod on the carton conveying cylinder 605 extends. When the piston rod of the carton conveying cylinder 605 retracts, the carton conveying shaft 602 rotates at a certain angle. When 602 rotates, the carton conveyor belt 604 rotates. The carton conveyor belt 604 is evenly provided with slots. When the carton conveyor belt 604 rotates, it pushes the bottom of the packaging box 15 to move. After the bottoms of multiple packaging boxes 15 move, they separate from the carton conveyor belt 604. Due to the weight of the packaging box 15 itself, the bottom of the packaging box 15 slides onto the carton conveyor support plate 607 for support, and the top of the packaging box 15 separates from the carton positioning wheel 615. The sides of the packaging box 15 are supported by multiple carton positioning blocks 611. When the box forming device 7 grabs the carton, the suction cup 708 contacts the outermost packaging box 15 on the carton conveyor support plate 607 and grabs the packaging box 15.

[0025] Multiple carton positioning cylinders 612 are fixed on the frame 1 above the carton conveying support plate 607, and carton positioning plates 613 are fixed to the piston rods of the carton positioning cylinders 612. When the bottom of the packaging box 15 slides to the position of the carton conveying support plate 607, the carton positioning cylinder 612 is activated, the piston rod of the carton positioning cylinder 612 extends, the carton positioning plate 613 descends, and the carton positioning plate 613 neatly stacks the packaging boxes 15 on the carton conveying support plate 607 to ensure that the suction cup 708 accurately grips them.

[0027] This embodiment discloses a box-retrieving and forming device. Based on the structure and principle of Embodiment 1, this embodiment further includes a box-retrieving support rod 713 fixed on the box-retrieving slide 703. The box-retrieving support rod 713 supports the box-retrieving fixing plate 707.

[0028] The above are merely preferred embodiments of the present invention. It should be noted that, for those skilled in the art, various changes, modifications, substitutions and variations can be made to these embodiments without departing from the technical principles of the present invention. These changes, modifications, substitutions and variations should also be considered within the scope of protection of the present invention.
