Description

Technical Field

[0001] This utility model relates to the field of paper box forming technology, and in particular to an adjustable-size packaging paper box forming device. Background Technology

[0002] The method of making paper boxes using a paper box forming machine has the advantages of high production efficiency and good forming quality. Therefore, it has increasingly replaced the traditional manual paper box making method and become the mainstream paper box manufacturing technology.

[0003] In existing technologies, paper box forming machines typically form paper boxes by pressing the cardboard to be folded onto the forming mold using a paper box forming mechanism. The forming mold usually consists of four sets of plates, each with a guide surface integrally formed on its end face to guide the cardboard to fold and position smoothly during the forming process. However, the fixed-angle guide surface has certain drawbacks. For example, for thicker cardboard, the fixed-angle guide surface may cause the cardboard to jam or fold insufficiently, while for thinner cardboard, the fixed-angle guide surface may cause the cardboard to over-fold or deviate from the preset trajectory. Therefore, it is necessary to propose an adjustable-size packaging paper box forming device to address the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an adjustable-size packaging paper box forming device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An adjustable-size packaging box forming device includes a base plate, a side plate fixedly connected to the upper end of the base plate, and four sets of forming plates mounted on the upper end of the base plate by screws. The four sets of forming plates are symmetrically arranged in pairs, and the forming plates on the left and right sides are sized as the other two sets of forming plates. A sliding groove is formed on the outer wall of the forming plate, and a guide plate is rotatably connected in the sliding groove. The end of the guide plate is inclined and smoothly transitioned. A fixing plate is fixedly connected to the side wall of the forming plate, and a connecting rod is slidably connected in the fixing plate. A pulley is fixedly connected to the end of the connecting rod, and the pulley contacts the back of the guide plate. A driving mechanism for driving the connecting rod to slide is installed on the outer wall of the fixing plate.

[0007] Preferably, the driving mechanism includes a threaded rod rotatably connected to the lower end face of the fixed plate, a slider is threadedly connected to the threaded section of the threaded rod, and one end of the connecting rod passes through the fixed plate body and is fixedly connected to the end face of the slider.

[0008] Preferably, a rotating block is fixedly connected to the end of the threaded rod, and multiple sets of grooves are respectively on the outer circumference of the outer wall, and a side plate is fixedly connected to the outer wall of the bottom plate.

[0009] Preferably, an electric telescopic rod is fixedly connected to the end face of the side plate, and a push plate is fixedly connected to the telescopic end of the electric telescopic rod.

[0010] Preferably, the outer walls on both sides of the molding plate are slidably connected with insert rods, which penetrate into the groove and extend slidably into the guide plate.

[0011] Preferably, a sliding plate is fixedly connected to the other end of the insertion rod, a spring is fixedly connected to the outer wall of the sliding plate, and the other end of the spring is fixedly connected to the side wall of the molding plate.

[0012] This utility model has the following beneficial effects:

[0013] 1. This utility model uses an adjustable forming plate and guide plate to flexibly adjust for packaging boxes of different sizes. By rotating the rotating block to drive the threaded rod to move the slider, the angle of the guide plate can be dynamically adjusted, ensuring that the cardboard is subjected to uniform force and moves smoothly during the forming process, avoiding jamming or excessive folding, and improving the versatility and forming accuracy of the equipment.

[0014] 2. This utility model achieves quick disassembly and installation through the elastic connection between the insertion rod 15 and the spring 5. The operator only needs to manually pull the slide plate 16 to compress the spring 5 to detach the insertion rod 15 from the guide plate 9 and quickly complete the replacement. The elastic pressure of the spring 5 ensures that the insertion rod 15 is always tightly attached to the guide plate 9. Attached Figure Description

[0020] 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.

[0021] Reference Figure 1-4 An adjustable-size packaging paper box forming device includes a base plate 1, a side plate 2 fixedly connected to the upper end of the base plate 1, and four sets of forming plates 6 installed on the upper end of the base plate 1 by screws. The four sets of forming plates 6 are symmetrically arranged in pairs, and the forming plates 6 on the left and right sides are sized to be the same as the other two sets of forming plates 6. A sliding groove 8 is opened on the outer wall of the forming plate 6, and a guide plate 9 is rotatably connected in the sliding groove 8. The end of the guide plate 9 is inclined and smoothly transitioned. A fixing plate 7 is fixedly connected to the side wall of the forming plate 6, and a connecting rod 13 is slidably connected in the fixing plate 7. A pulley 14 is fixedly connected to the end of the connecting rod 13, and the pulley 14 contacts the back of the guide plate 9. A driving mechanism for driving the connecting rod 13 to slide is installed on the outer wall of the fixing plate 7.

[0022] Furthermore, the design of the slide 8 and guide plate 9 enables dynamic adjustment of the guide surface angle, adapting to cardboard of different thicknesses or materials and avoiding the jamming or over-folding problems caused by traditional fixed angles. The contact design between the pulley 14 and the connecting rod 13 ensures that the guide plate 9 maintains smooth movement during adjustment, improving forming accuracy.

[0023] The driving mechanism includes a threaded rod 10 rotatably connected to the lower end face of the fixed plate 7, a slider 12 threadedly connected to the threaded section of the threaded rod 10, and a connecting rod 13 with one end passing through the body of the fixed plate 7 and fixedly connected to the end face of the slider 12.

[0024] Furthermore, the angle of the guide plate 9 can be controlled by rotating the threaded rod 10, and the sliding connection between the connecting rod 13 and the fixed plate 7 ensures that the pulley 14 can move vertically up and down without limiting the slider 12.

[0025] The threaded rod 10 is fixedly connected to a rotating block 11 at its end, and has multiple sets of grooves on its outer circumference. The bottom plate 1 is fixedly connected to a side plate 2 on its outer wall. An electric telescopic rod 3 is fixedly connected to the end face of the side plate 2. A push plate 4 is fixedly connected to the telescopic end of the electric telescopic rod 3.

[0026] Furthermore, by extending the telescopic end of the electric telescopic rod 3, the push plate 4 can be driven to press down, thereby directly acting on the cardboard and pushing the cardboard to slide smoothly along the guide surface of the forming plate 6 and complete the folding and forming process.

[0027] Both sides of the outer wall of the molding plate 6 are slidably connected with insert rods 15. The insert rods 15 pass through the groove 8 and slide to the guide plate 9. The other end of the insert rod 15 is fixedly connected to the slide plate 16. The outer wall of the slide plate 16 is fixedly connected to the spring 5. The other end of the spring 5 is fixedly connected to the side wall of the molding plate 6.

[0028] Furthermore, the guide plate 9 can be quickly replaced by using the sliding rod 15, and the spring 5 provides continuous pressure to the rod 15 through the elastic connection between the slide plate 16 and the rod 15, ensuring the stability of the rod 15 when connected to the guide plate 9.

[0029] In this invention, the device is used as follows: When different cardboard types need to be adapted, the operator can adjust the position of the four forming plates 6 by removing screws, thus enabling the forming of packaging boxes of different sizes. Then, rotating the rotating block 11 drives the threaded rod 10 to rotate, causing the slider 12 to slide vertically, forcing the pulley 14 to drive the guide plate 9 to rotate around the slide groove 8, achieving dynamic angle adjustment. Subsequently, the electric telescopic rod 3 is activated to drive the push plate 4 to press down, pushing the cardboard along the guide surface of the forming plate 6. The smooth transition surface of the guide plate 9 ensures that the cardboard is subjected to uniform force, avoiding jamming or excessive folding, ultimately achieving precise forming.

[0030] During long-term use, if the guide plate 9 needs to be replaced, the operator can manually pull the slide plate 16 to compress the spring 5, causing the insertion rod 15 to disengage from the guide plate 9. This allows for quick removal of the old guide plate from the slide groove 8 and installation of the new module. The elastic pressure of the spring 5 ensures that the insertion rod 15 remains tightly fitted inside the guide plate 9, ensuring the stability of the insertion.

[0031] 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.
