Description

Technical Field

[0001] This utility model relates to the field of packaging box processing technology, and in particular to an embossing machine for packaging boxes. Background Technology

[0002] A creasing machine is a specialized piece of equipment used to crimp and cut various types of cardboard, corrugated cardboard, plastic sheets, and leather products. Existing creasing machines crease cardboard boxes by moving a creasing plate up and down. However, after the creasing plate presses the box, it can easily get stuck on it. When the creasing plate moves upwards, the box also moves upwards, requiring the operator to pull it down, which is cumbersome and may even damage the box. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies where packaging boxes easily get stuck on the embossing plate, affecting the feeding speed, and to propose an embossing machine for packaging boxes.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] Design a creasing machine for packaging boxes, including a base, a mounting frame fixedly mounted on the upper surface of the base, an electric telescopic rod fixedly mounted on the top of the mounting frame, a lifting frame fixedly mounted on the lower end of the electric telescopic rod, a fixed rod fixedly mounted inside the lifting frame, a creasing plate fixedly mounted on the lower end of the fixed rod by bolts, movable rods movably extending through both sides of the lifting frame, a spring sleeved on the outer side of the movable rod located inside the lifting frame, one end of the spring fixedly connected to the inner wall of the lifting frame, and the other end fixedly connected to a fixed plate, the fixed plate fixedly connected to the movable rod, and a positioning plate fixedly mounted on the lower end of the movable rod.

[0006] Preferably, a support rod is also fixedly installed on the upper surface of the lifting frame, and the upper end of the support rod extends through to the top of the mounting frame.

[0007] Preferably, the electric telescopic rod and the support rod are parallel in length direction and are both vertically arranged.

[0008] Preferably, the length direction of the movable rod and the spring is parallel to the length direction of the electric telescopic rod.

[0009] Preferably, the length of the lower end of the positioning plate is not less than the length of the indentation plate.

[0010] Preferably, a rubber pad is fixedly wrapped around the lower surface of the positioning plate.

[0011] Preferably, the base has an internal movable cavity, a lead screw is rotatably installed inside the movable cavity, a pair of sliders are threaded on the outside of the lead screw, and the upper end of the sliders extends through to the top of the base and is fixedly installed with a limit block.

[0012] Preferably, the lead screw is a bidirectional lead screw and is horizontally arranged in the length direction, and the two sliders are respectively threaded to both ends of the lead screw.

[0013] The present invention discloses a creasing machine for packaging boxes, which has the following advantages: During operation, the creasing machine can move the creasing plate and the positioning plate up and down via an electric telescopic rod. Based on the height difference between the positioning plate and the creasing plate, the positioning plate first contacts the packaging box to press and position it, and then the positioning plate separates from the packaging box after the creasing plate. This allows the packaging box to separate quickly from the creasing plate, avoids the packaging box from getting stuck on the creasing plate, and improves the efficiency of packaging box unloading.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Example 1: Refer to Figure 1-4A creasing machine for packaging boxes includes a base 1, a mounting frame 2 fixedly mounted on the upper surface of the base 1, an electric telescopic rod 3 fixedly mounted on the top of the mounting frame 2, and a lifting frame 4 fixedly mounted on the lower end of the electric telescopic rod 3. The electric telescopic rod 3 can drive the lifting frame 4 to move up and down. A support rod 5 is also fixedly mounted on the upper surface of the lifting frame 4, with the upper end of the support rod 5 extending through to the top of the mounting frame 2. The electric telescopic rod 3 and the support rod 5 are parallel in length and both are vertically arranged. The support rod 5 can provide support and guidance, ensuring that the lifting frame 4 can maintain stability during up and down movement.

[0021] The lifting frame 4 has a fixed rod 10 inside, and an indentation plate 11 is fixedly installed at the lower end of the fixed rod 10 by bolts. When the lifting frame 4 moves up and down, the indentation plate 11 can move up and down through the fixed rod 10, and the indentation plate 11 can be used to indent the packaging box. Furthermore, the fixed rod 10 and the indentation plate 11 are easy to disassemble, and an indentation plate 11 of a specified size can be replaced as needed to flexibly meet the indentation requirements of packaging boxes of different sizes.

[0022] Movable rods 6 are movably connected through both sides of the lifting frame 4. The length direction of the movable rods 6 and the spring is parallel to the length direction of the electric telescopic rod 3. The part of the movable rod 6 located inside the lifting frame 4 is fitted with a spring 8. As shown in the attached figure, one end of the spring 8 is fixedly connected to the inner wall of the lifting frame 4, and the other end is fixedly connected to a fixing plate 7. The fixing plate 7 is fixedly connected to the movable rod 6. Under its own weight and the elastic force of the spring 8, the fixing plate 7 can always be located at the bottom inside the lifting frame 4. A positioning plate 9 is fixedly installed at the lower end of the movable rod 6. The length of the lower end of the positioning plate 9 is not less than the length of the indentation plate 11. When the positioning plate 9 moves downward, it can press the packaging box.

[0023] When the lifting frame 4 moves downwards, it drives the positioning plate 9 downwards via the movable rod 6. Simultaneously, the lifting frame 4 also drives the indentation plate 11 downwards. Since the positioning plate 9 is lower than the indentation plate 11, the positioning frame 9 contacts the packaging box before the indentation plate 11. A rubber pad is fixedly wrapped around the lower surface of the positioning plate 9, allowing the positioning frame 9 to gently press against the packaging box. Only then will the indentation plate 11 contact the packaging box. As the lifting frame 4 continues to move downwards, it can drive the indentation plate 11 to indent the packaging box. However, the positioning frame 9 cannot move downwards, so there will be relative movement between the fixed plate 7 and the lifting frame 4. The spring 8 is compressed. After the indentation plate 11 indents the packaging box, the lifting frame 4 moves upwards, driving the indentation plate 11 and the movable rod 6 upwards. When the indentation plate 11 separates from the packaging box first, the positioning frame 9 still exerts a squeezing effect on the packaging box, allowing the indentation plate 11 to quickly separate from the packaging box. Finally, the positioning frame 9 separates from the packaging box as the lifting frame 4 moves upwards.

[0024] Working principle: During the operation of the creasing machine, the packaging box is placed on the upper surface of the base 1. Scales can be engraved on the upper surface of the base 1 to define the placement position of the packaging box. Then, the electric telescopic rod 3 is activated, driving the lifting frame 4 downwards. The downward movement of the lifting frame 4 causes the creasing plate 11 and the positioning plate 9 to move downwards as well. The positioning plate 9 will first contact the surface of the packaging box, pressing it down to ensure that the box's position does not shift. Then, the creasing plate 11 will contact the surface of the packaging box, creasing it. Afterwards, the electric telescopic rod 3 drives the lifting frame 4 upwards. The upward movement of the lifting frame 4 will cause the creasing plate 11 to move away from the packaging box. At this time, the packaging box, under the elastic pressure of the positioning plate 9, will quickly detach from the creasing plate 11, preventing the packaging box from getting stuck on the creasing plate 11 and moving upwards with it.

[0025] Example 2: In Example 1, since the packaging box was positioned manually by observing scales or reference objects, there may be deviations, which could affect the accuracy of the indentation position. Therefore, this example is proposed. (Refer to...) Figure 1-2 In another preferred embodiment of this utility model, based on embodiment 1, a movable cavity 12 is provided inside the base 1. A lead screw 13 is rotatably installed inside the movable cavity 12. A motor is connected to the end of the lead screw 13, and the motor is fixedly installed inside the base 1. The motor can drive the lead screw 13 to rotate. A pair of sliders 14 are threaded on the outside of the lead screw 13. The lead screw 13 is a bidirectional lead screw and is horizontally arranged in the length direction. The two sliders 14 are respectively threaded to both ends of the lead screw 13. During the rotation of the lead screw 13, it can drive the two sliders 14 to move closer or further away from each other at the same time. The upper end of the slider 14 extends through to the top of the base 1 and is fixedly installed with a limit block 15. The movement of the slider 14 will drive the limit block 15 to move. When the motor is started, the motor will drive the lead screw 13 to rotate. The rotation of the lead screw 13 can drive the sliders 14 on both sides to move closer or further away from each other at the same time, thereby driving the limit blocks 15 to move closer or further away from each other. The limit blocks 15 can center and clamp the packaging box, which can ensure that the position of the packaging box is more accurate and the indentation of the packaging box is more precise.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
