Description

Technical Field

[0001] This utility model relates to the field of packaging box printing positioning technology, and specifically discloses a positioning mechanism for packaging box printing. Background Technology

[0002] Packaging boxes, as the name suggests, are boxes used to package products. They can be classified by material, such as: cardboard boxes, tin boxes, wooden boxes, cloth boxes, leather boxes, acrylic boxes, corrugated packaging boxes, etc. The functions of packaging boxes include: ensuring the safety of products during transportation and enhancing the product's grade.

[0003] A positioning mechanism for packaging box printing, disclosed in Chinese Patent No. CN221161857U, includes a printing device body. A working groove is formed on one side of the upper end face of the printing device body, and a cavity is formed on one side of the inner wall of the working groove. A first drive motor is disposed inside the cavity. This utility model provides a positioning mechanism for packaging box printing that facilitates both printing and adjustment. It solves the problem that most existing packaging box printing positioning mechanisms require manual adjustment of each packaging box to the appropriate position during printing, resulting in low work efficiency and high labor costs. It also solves the problem that most existing packaging box printing positioning mechanisms require adjustment of the entire device when changing packaging boxes, which is very troublesome and time-consuming.

[0004] However, this device still has certain limitations in practical applications. Its positioning method mainly relies on a conveyor belt to transport the packaging boxes, with positioning achieved through side limiting plates during transport. Because the packaging boxes are in direct contact with the limiting plates during transport, friction occurs between them, which can easily affect the smoothness of the transport. In severe cases, it may cause the packaging boxes to stop or even cause blockages, thus adversely affecting printing quality and production efficiency. Utility Model Content

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0018] Please see Figure 1-5 A positioning mechanism for printing packaging boxes includes a base 1, and further includes: A conveying and positioning mechanism is installed inside the base 1. The conveying and positioning mechanism is used to convey and position the packaging box. The conveying and positioning mechanism includes a first conveyor 2 installed inside the base 1. The base 1 has two mounting plates 3 located above the first conveyor 2 and distributed front to back. A second conveyor 4 is installed on the lower end of each of the two mounting plates 3. The two second conveyors 4 rotate relative to each other. The left ends of the opposite side walls of the two second conveyors 4 are set as symmetrically distributed inclined structures. A rotating shaft 5 located on the right side of the mounting plate 3 is rotatably connected inside the base 1. A positioning plate 6 is fixedly connected to the outer wall of the rotating shaft 5. A touch sensor 7 is installed on the left side wall of the positioning plate 6. The printing mechanism is located on the upper surface of the base 1. The printing mechanism prints on the packaging box. The printing mechanism includes a first gantry 8 fixedly connected to the upper surface of the base 1. A first electric telescopic rod 9 is installed on the upper surface of the first gantry 8. The output end of the first electric telescopic rod 9 extends into the interior of the first gantry 8 and is fixedly connected to a printing block 10.

[0019] In this embodiment: First, the distance between the two second conveyors 4 is adjusted according to the width of the packaging box to be processed, ensuring that the spacing between the two second conveyors 4 matches the width of the packaging box. The adjustable second conveyors 4 can accommodate packaging boxes of different widths. After adjustment, the packaging box is placed on the first conveyor 2, and the first conveyor 2 transports the packaging box to the right. When the front end of the packaging box enters the area between the two second conveyors 4, the second conveyors 4 rotate relative to each other, and the inclined structure on their left end smoothly guides the packaging box into the clamping and conveying state. Since the first conveyor 2 and the two second conveyors 4 operate at the same speed, the packaging box is driven uniformly in multiple directions during transport, effectively avoiding stagnation, deviation, or blockage caused by single-direction transport or frictional resistance. The packaging box continues to move to the right under the clamping and conveying of the second conveyors 4 until its right side contacts the positioning plate 6. At this time, the left side of the positioning plate 6... The side-mounted touch sensor 7 detects the packaging box's arrival signal and transmits it to an external control computer. The control computer then instructs the first conveyor 2 and the two second conveyors 4 to stop, and controls the first electric telescopic rod 9 to move the printing block 10 downward (the printing block 10 has an ink cartridge inside, and its lower end surface has a printed pattern that communicates with the ink cartridge; this is a well-known and mature existing technology, and will not be described in detail here). This allows the printed pattern of the printing block 10 to come into contact with the printed surface of the packaging box, thereby printing the packaging box through the printing block 10. After the printing is completed, the first electric telescopic rod 9 moves the printing block 10 upward to reset it. At the same time, the positioning plate 6 rotates upward to clear the conveying channel. Then, the first conveyor 2 and the two second conveyors 4 start running again, conveying the printed packaging box to the next processing position. Then, the second electric telescopic rod 18 moves the positioning plate 6 to reset, and then the above steps are repeated to print other packaging boxes.

[0020] As a technical optimization of this utility model, a second gantry frame 11 is fixedly connected to the upper end of the base 1. A cavity 12 is opened inside the second gantry frame 11. A notch is opened through the upper end of the second gantry frame 11. A movable plate 13 extending into the cavity 12 through the notch is fixedly connected to the upper end of the two mounting plates 3. A bidirectional screw 14 threadedly connected to the two movable plates 13 is rotatably connected inside the cavity 12. One end of the bidirectional screw 14 extends to the front of the second gantry frame 11 and is fixedly connected to a torsion block.

[0021] In this embodiment: the operator rotates the bidirectional screw 14 by twisting the block. The bidirectional screw 14 drives the two moving plates 13 to move towards or away from each other. The moving plates 13 synchronously drive the two second conveyors 4 through the mounting plate 3 to adjust their relative positions, thereby adjusting the distance between the two second conveyors 4 to ensure that the distance between the two second conveyors 4 matches the width of the packaging box.

[0022] As a technical optimization of this utility model, a sliding hole 15 is provided through the upper end face of the second gantry 11, and a measuring block 16 extending through the sliding hole 15 to the upper end face of each of the two moving plates 13 is fixedly connected to the measuring block 16, which extends to the upper part of the second gantry 11. The two measuring blocks 16, the two moving plates 13, the two mounting plates 3 and the two second conveyors 4 are all located on the same vertical plane.

[0023] In this embodiment: During the adjustment process, the measuring block 16 fixed to the upper end of the moving plate 13 moves along the sliding hole 15. Since the two measuring blocks 16, the two moving plates 13, the two mounting plates 3 and the two second conveyors 4 are all located on the same vertical plane, the distance between the two second conveyors 4 can be observed intuitively through the two measuring blocks 16.

[0024] As a technical optimization of this utility model, a fixing block 17 is fixedly connected to the right end of the rear end face of the base 1, a second electric telescopic rod 18 is installed on the left side wall of the fixing block 17, a rack 19 is fixedly connected to the output end of the second electric telescopic rod 18, and one end of the rotating shaft 5 extends to the rear of the base 1 and is fixedly connected to a gear 20 that meshes with the rack 19.

[0025] In this embodiment: the second electric telescopic rod 18 is activated, pushing the rack 19 to move to the left. The rack 19 drives the gear 20 meshing with it to rotate, causing the rotating shaft 5 and the positioning plate 6 fixed thereon to rotate upward, making room for the conveying channel.

[0026] As a technical optimization of this utility model, the upper end face of the second gantry 11 is provided with scale lines that match the two measuring blocks 16.

[0027] In this embodiment, the distance between the two measuring blocks 16 can be precisely adjusted using the scale lines.

[0028] As a technical optimization of this utility model, the first conveyor 2 and the two second conveyors 4 operate at the same speed.

[0029] In this embodiment, the first conveyor 2 and the two second conveyors 4 operate at the same speed, which enables the packaging boxes to be transported smoothly and steadily.

[0030] As a technical optimization of this utility model, the first conveyor 2, the second conveyor 4, the touch sensor 7, the first electric telescopic rod 9, and the second electric telescopic rod 18 are all electrically connected to an external control computer.

[0031] In this embodiment, an external control computer can receive signals from the touch sensor 7 and control the first conveyor 2, the second conveyor 4, the first electric telescopic rod 9, and the second electric telescopic rod 18.

[0032] The working principle and usage process of this utility model are as follows: In use, firstly, adjust the distance between the two second conveyors 4 according to the width of the packaging box to be processed. Specifically, the operator rotates the bidirectional screw 14 by twisting the lever. The bidirectional screw 14 drives the two moving plates 13 to move towards or away from each other. The moving plates 13 synchronously drive the two second conveyors 4 through the mounting plate 3 to adjust their relative positions, thereby adjusting the distance between the two second conveyors 4. During the adjustment process, the measuring block 16 fixed to the upper end of the moving plate 13 moves along the sliding hole 15. Furthermore, due to the movement of the two measuring blocks 16, the two moving plates 13, and the two... The mounting plate 3 and the two second conveyors 4 are located on opposite side walls in the same vertical plane. Therefore, the distance between the two second conveyors 4 can be directly observed through the two measuring blocks 16. After adjustment, the packaging box is placed on the first conveyor 2, and the packaging box is conveyed to the right by the first conveyor 2. When the front end of the packaging box enters the area between the two second conveyors 4, the second conveyors 4 rotate relative to each other, and the inclined structure set at its left end can smoothly guide the packaging box into the clamping and conveying state. Since the first conveyor 2 and the two second conveyors 4 operate at the same speed, the packaging box is conveyed through... During the process, the packaging box is driven uniformly in multiple directions, effectively avoiding stagnation, deviation, or blockage caused by unidirectional conveying or frictional resistance. Under the clamping and conveying of the second conveyor 4, the packaging box continues to move to the right until its right side contacts the positioning plate 6. At this time, the touch sensor 7 installed on the left side of the positioning plate 6 detects the packaging box's positioning signal and transmits the signal to the external control computer. The control computer then commands the first conveyor 2 and the two second conveyors 4 to stop, and controls the first electric telescopic rod 9 to drive the printing block 10 downward, so that the printing pattern of the printing block 10 abuts against the printing surface of the packaging box, thereby printing... The printing block 10 prints on the packaging box. After the printing is completed, the first electric telescopic rod 9 moves the printing block 10 upward to reset. At the same time, the second electric telescopic rod 18 moves, pushing the rack 19 to the left. The rack 19 drives the gear 20 meshing with it to rotate, which drives the rotating shaft 5 and the positioning plate 6 fixed on it to rotate upward, making room for the conveyor channel. Then the first conveyor 2 and the two second conveyors 4 start running again, conveying the printed packaging box to the next processing position. Then the second electric telescopic rod 18 moves the positioning plate 6 to reset. Then the above steps are repeated to print on other packaging boxes.
