Abstract
Description
Technical Field
[0001] This utility model relates to the field of packaging box production technology, specifically a forming device for packaging box production. Background Technology
[0002] Packaging boxes are boxes used to package products. They can be classified by material into cardboard boxes, tin boxes, wooden boxes, and leather boxes. Their functions include ensuring the safety of products during transportation, enhancing the product's grade, and protecting and displaying products. They are now widely used in industries such as electronics, food, beverages, wine, tea, cigarettes, pharmaceuticals, health products, cosmetics, small appliances, clothing, toys, and sporting goods, as well as in product packaging and related industries. It is an indispensable industry.
[0003] A search revealed a packaging box face paper forming device with application number 201921833262.0. This device attaches glued face paper to the bottom of the packaging box. The central shaft assembly and upper transmission assembly hold the packaging box and then move it downwards to allow the packaging box with the face paper to enter the interior of the forming head assembly. The forming head assembly then attaches the face paper to the box body. After the face paper is formed, the packaging box is pushed into the product chute by the pusher cylinder and flows out to the next process. However, the main mold body inside the device can only press the same product. When attaching face paper to packaging boxes of different sizes, it is necessary to replace it with a mold body of the same size as the production packaging box, which limits its application range. In addition, the main mold body is usually made of materials such as wood and rubber, and it needs to be remade every time the product is changed. Utility Model Content
[0004] Therefore, the purpose of this utility model is to provide a molding device for packaging box production to solve the technical problems in the background art mentioned above.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a forming device for packaging box production, comprising a base, a first hydraulic cylinder and a mounting frame connected to the top of the base via a gantry frame, a guide frame connected to the output end of the first hydraulic cylinder, a guide groove formed on the outside of the guide frame, two sliders, a threaded block and a fixing block connected inside the guide groove, a first motor mounted on the top of the guide frame, a screw connected to the output end of the first motor and threadedly connected to the threaded block, a second motor mounted on the bottom of the mounting frame, a bidirectional lead screw connected to the output end of the second motor and rotatably connected to the fixing block, a second guide rod connected to one side of each of the two sliders, a first guide rod installed inside the threaded block, a translation frame connected to the outside of the first guide rod, the second guide rod and the bidirectional lead screw, a connecting rod connected to the outer surface of the first guide rod, a folding plate connected to one end of the connecting rod, and a receiving plate connected to the bottom of the base.
[0006] Furthermore, the number of folding plates is four, and the four folding plates are distributed in a rectangular array.
[0007] By adopting the above technical solution, the width and length between the folds refer to the length and width of the rectangle after the overall projection of the four folds. By adjusting the length or width between two adjacent folds, the projection area between the four folds can be expanded, thereby adapting to different packaging boxes. By supporting packaging boxes of different sizes, it is convenient to stick the face paper afterward.
[0008] Furthermore, the translation frame is internally connected to a cross roller guide rail via a sliding rod.
[0009] By adopting the above technical solution, the SVW type of cross roller guide is an existing technology. It consists of a W-shaped rail with V-grooves on both sides, two SV-shaped rails, and two R-shaped roller retainers. The two R-shaped roller retainers are movably connected to the translation frame on both sides through slide rods. One side of each of the two SV-shaped rails is connected to two folding plates. Under the drive of the connecting rod, the folding plates move. The cross roller guide guides the folding plates to prevent them from flipping and shifting during movement, which would affect the adjustment accuracy of the length between the folding plates.
[0010] Furthermore, the sliding rod passes through the translation frame.
[0011] By adopting the above technical solution, when the translation frame moves downward, it can avoid the translation frame from driving the cross roller guide rail downward, thereby avoiding the conflict between the lateral and longitudinal movements that affect the length adjustment when adjusting the length between the folding plates.
[0012] Furthermore, the cross-sections of the threaded block, slider, and fixed block are all convex, and the threaded block, slider, and fixed block are all slidably connected to the guide frame through guide grooves.
[0013] By adopting the above technical solution, when adjusting the length between the folding plates, the operator starts the first motor. The output end of the first motor drives the screw to rotate. Guided by the guide groove, the threaded block drives the first guide rod to move down. Under the drive of the first guide rod, the translation frame, slider, fixing block, lead screw and second motor move down at the same time. At the same time, during the process of the slider moving down, it drives the second guide rod to press down the connecting rod. Guided by the cross roller guide rail, one end of the connecting rod pushes the folding plate to move, thereby completing the length adjustment between the folding plates.
[0014] Furthermore, the translation frame is slidably connected to the first guide rod and the second guide rod respectively, and the translation frame is threadedly connected to the bidirectional lead screw.
[0015] By adopting the above technical solution, when adjusting the width between the folding plates, the staff starts the second motor. The output end of the second motor drives the bidirectional lead screw to rotate, thereby causing the two sets of translation frames to move in opposite directions. Guided by the second guide rod, the translation frames push the connecting rod, causing the folding plates connected to the connecting rod to move, thereby completing the adjustment of the width between the folding plates.
[0016] Furthermore, the mounting bracket is movably connected to the guide bracket.
[0017] By adopting the above technical solution, the top of the mounting plate passes through the guide frame, and the mounting plate provides support for the second motor, enabling the second motor to move together with the bidirectional lead screw, thus preventing the bidirectional lead screw from bending under the influence of the motor's gravity and affecting the normal operation of the bidirectional lead screw.
[0018] Furthermore, there are four connecting rods, with two connecting rods forming a group. The connecting rods in each group are arranged in a crisscross pattern and are movably connected to the second guide rod.
[0019] By adopting the above technical solution, the two sets of connecting rods drive the folding plate to move under the pressure of the second guide rod. Through the cross-shaped arrangement and cooperation with the cross roller guide rail, the folding plate can move in a predetermined direction, avoiding deviation during the movement of the folding plate.
[0020] Furthermore, the cross-section of the translation frame is U-shaped.
[0021] By adopting the above technical solution, driven by the bidirectional lead screw and guided by the second guide rod, the translation frame can push the connecting rod to move, thereby adjusting the width between the folding plates. Through the "U"-shaped setting, the translation frame can drive the connecting rod to move back and forth.
[0022] Furthermore, the base is connected to four second hydraulic cylinders at its bottom, with two cylinders forming a group, and the output ends of the four hydraulic cylinders are respectively connected to limit plates.
[0023] By adopting the above technical solution, grooves are provided in the front and rear limiting plates, and the left and right limiting plates are slidably connected to the front and rear limiting plates through the grooves. The staff starts the second hydraulic cylinder respectively. Driven by the output end of the second hydraulic cylinder, the length of the packaging box is adjusted by adjusting the distance between the front and rear limiting plates, and the width of the packaging box is adjusted by adjusting the distance between the left and right limiting plates, so that the cavity corresponds exactly to the size of the packaging box after the face paper is glued. Through the cooperation of the cavity and the folding plate, the face paper can be more tightly attached to the packaging box to be glued.
[0024] In summary, the present invention has the following main advantages:
[0025] 1. This utility model, by setting a guide frame, screw, threaded block, connecting rod and second guide rod, adjusts the length between the folding plates. When the operator starts the first motor, the output end of the first motor drives the screw to rotate. Guided by the guide groove, the threaded block drives the first guide rod to move down. Under the drive of the first guide rod, the translation frame, slider, fixing block, lead screw and second motor move down at the same time. At the same time, during the movement of the slider down, it drives the second guide rod to press down the connecting rod. Guided by the cross roller guide rail, one end of the connecting rod pushes the folding plates to move, thereby completing the length adjustment between the folding plates.
[0026] 2. This utility model is equipped with a second motor, a bidirectional lead screw, and a translation frame. When adjusting the width between the folding plates, the operator starts the second motor, and the output end of the second motor drives the bidirectional lead screw to rotate, thereby causing the two sets of translation frames to move in opposite directions. Guided by the second guide rod, the translation frames push the connecting rod, causing the folding plates connected to the connecting rod to move, thereby completing the width adjustment between the folding plates.
[0027] By adjusting the length or width between two adjacent folding plates in the above manner, the folding plates can adapt to packaging boxes of different sizes. When changing products, there is no need to remake and disassemble them. They can support packaging boxes of different sizes and facilitate subsequent application of face paper.

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0035] The embodiments of this utility model will be described below based on its overall structure.
[0036] Example 1: A forming apparatus for packaging box production, such as Figures 1-5 As shown, the system includes a base 1. A first hydraulic cylinder 2 and a mounting bracket 14 are connected to the top of the base 1 via a gantry frame. A guide frame 3 is connected to the output end of the first hydraulic cylinder 2. A guide groove 4 is formed on the outside of the guide frame 3. Two sliders 5, a threaded block 7, and a fixing block 6 are connected inside the guide groove 4. A first motor 13 is mounted on the top of the guide frame 3. A screw 8 is connected to the output end of the first motor 13, and the screw 8 is threadedly connected to the threaded block 7. A second motor 15 is mounted on the bottom of the mounting bracket 14. A bidirectional lead screw 11 is connected to the output end of the second motor 15, and the bidirectional lead screw 11 is rotatably connected to the fixing block 6. A second guide rod 10 is connected to one side of each of the two sliders 5. A second guide rod 10 is installed inside the threaded block 7. A guide rod 9, a first guide rod 9, a second guide rod 10, and a bidirectional lead screw 11 are externally connected to a translation frame 12. A connecting rod 16 is connected to the outer surface of the first guide rod 9. One end of the connecting rod 16 is connected to a folding plate 19. A receiving plate 22 is connected to the bottom of the base 1. There are four folding plates 19, and the four folding plates 19 are arranged in a rectangular array. The width and length between the folding plates 19 refer to the length and width of the rectangle after the overall projection of the four folding plates 19. By adjusting the length or width between two adjacent folding plates 19, the projection area between the four folding plates 19 can be expanded, thereby adapting to different packaging boxes. By supporting packaging boxes of different sizes, it is convenient to stick the face paper later.
[0037] See Figures 1-4 In the above embodiment, the translation frame 12 is connected to the cross roller guide 17 through the slide rod 18. The cross roller guide 17 is of the SVW type, which is the prior art. It consists of a W-shaped rail with V grooves on both sides, two SV-shaped rails, and two R-shaped roller retainers. The two R-shaped roller retainers are movably connected to the translation frame 12 through the slide rod 18 on both sides. One side of each of the two SV-shaped rails is connected to two folding plates 19. Under the drive of the connecting rod 16, the folding plates 19 move. The cross roller guide 17 guides the folding plates 19 to avoid flipping and offset during the movement of the folding plates 19, which would affect the adjustment accuracy of the length between the folding plates 19.
[0038] See Figures 1-4In the above embodiment, the slide rod 18 passes through the translation frame 12. When the translation frame 12 moves down, it can prevent the translation frame 12 from driving the cross roller guide rail 17 to move down, thereby avoiding the conflict between the lateral and longitudinal movements when adjusting the length between the folding plates 19, which affects the length adjustment.
[0039] See Figure 3 and Figure 4 In the above embodiment, the cross-sections of the threaded block 7, the slider 5, and the fixed block 6 are all convex, and the threaded block 7, the slider 5, and the fixed block 6 are all slidably connected to the guide frame 3 through the guide groove 4. When adjusting the length between the folding plates 19, the operator starts the first motor 13. The output end of the first motor 13 drives the screw 8 to rotate. Guided by the guide groove 4, the threaded block 7 drives the first guide rod 9 to move down. Under the drive of the first guide rod 9, the translation frame 12, the slider 5, the fixed block 6, the lead screw, and the second motor 15 move down at the same time. At the same time, during the downward movement of the slider 5, the second guide rod 10 drives the connecting rod 16 to press down. Guided by the cross roller guide rail 17, one end of the connecting rod 16 pushes the folding plates 19 to move, thereby completing the length adjustment between the folding plates 19.
[0040] See Figure 3 and Figure 4 In the above embodiment, the translation frame 12 is slidably connected to the first guide rod 9 and the second guide rod 10 respectively, and the translation frame 12 is threadedly connected to the bidirectional lead screw 11. When adjusting the width between the folding plates 19, the operator starts the second motor 15. The output end of the second motor 15 drives the bidirectional lead screw 11 to rotate, thereby causing the two sets of translation frames 12 to move in opposite directions. Guided by the second guide rod 10, the translation frame 12 pushes the connecting rod 16, causing the folding plates 19 connected to the connecting rod 16 to move, thereby completing the width adjustment between the folding plates 19.
[0041] See Figures 1-4 In the above embodiment, the mounting bracket 14 is movably connected to the guide bracket 3, and the top of the mounting plate passes through the guide bracket 3. The mounting plate provides support for the second motor 15 and enables the second motor 15 to move together with the bidirectional lead screw 11, so as to avoid the bidirectional lead screw 11 bending under the influence of the motor's gravity and affecting the normal operation of the bidirectional lead screw 11.
[0042] See Figure 3 and Figure 4 In the above embodiment, there are four connecting rods 16, with two connecting rods 16 forming a group, for a total of two groups. Each group of connecting rods 16 is distributed in a cross pattern, and the connecting rods 16 are movably connected to the second guide rod 10. Under the downward pressure of the second guide rod 10, the two groups of connecting rods 16 respectively drive the folding plate 19 to move. Through the cross pattern arrangement and cooperation with the cross roller guide rail, the folding plate 19 can move in a predetermined direction, avoiding deviation during the movement of the folding plate 19.
[0043] See Figure 3 and Figure 4 In the above embodiment, the translation frame 12 has a U-shaped cross section. Driven by the bidirectional lead screw 11 and guided by the second guide rod 10, the translation frame 12 can push the connecting rod 16 to move, thereby adjusting the width between the folding plates 19. Through the U-shaped setting, the translation frame 12 can drive the connecting rod 16 to move back and forth.
[0044] Example 2: To prevent the face paper from shifting during adhesion, resulting in a loose bond between the face paper and the packaging box, Example 2 is an improvement upon Example 1. (See attached document for details.) Figure 1 , Figure 2 and Figure 5 The base 1 has four second hydraulic cylinders 20 connected to its bottom, with two cylinders forming a group. The output ends of the four hydraulic cylinders are connected to limit plates 21. The front and rear limit plates 21 have grooves. The left and right limit plates 21 are slidably connected to the front and rear limit plates 21 through the grooves. The operator starts the second hydraulic cylinders 20 respectively. Driven by the output ends of the second hydraulic cylinders 20, the length of the packaging box is adjusted by adjusting the distance between the front and rear limit plates 21. The width of the packaging box is adjusted by adjusting the distance between the left and right limit plates 21, so that the cavity corresponds exactly to the size of the packaging box after the face paper is glued. Through the cooperation of the cavity and the folding plate 19, the face paper can be more tightly attached to the packaging box to be glued.
[0045] The implementation principle of this utility model is as follows: The operator starts the second hydraulic cylinder 20. Driven by the output end of the second hydraulic cylinder 20, the length and width of the cavity formed between the four limiting plates 21 are adjusted by adjusting the distance between the front and rear limiting plates 21, so that the cavity corresponds exactly to the size of the packaging box after the face paper is glued. After adjustment, the packaged box with adhesive is placed above the cavity and aligned. Then, the first hydraulic cylinder 2 is started. The first hydraulic cylinder 2 drives the guide frame 3 and the folding plate 19 to move down and press down on the packaged box, cooperating with the cavity to adhere the face paper to the outside of the packaged box and complete the pressing. When pressing packaging boxes of different sizes, the operator first starts the first motor 13. The output end of the first motor 13 drives the screw 8 to rotate, cooperating with the guide groove 4, so that the threaded block 7... The first guide rod 9 moves downward, and simultaneously, under the combined action of the translation frame 12, the lead screw, and the second guide rod 10, the fixed block 6, the two sliders 5, and the mounting frame 14 move downward together. During the downward movement of the fixed block 6, the second guide rod 10 moves downward, and is limited and guided by the cross roller guide rail 17, causing the connecting rod 16 to push the folding plate 19, completing the length adjustment between the folding plates 19. Then, the operator starts the second motor 15, and the output end of the second motor 15 drives the bidirectional lead screw 11 to rotate, causing the two translation frames 12 to move in opposite directions. Under the push of the translation frames 12 and guided by the second guide rod 10, the width adjustment between the folding plates 19 is completed. By adjusting the length and width between the folding plates 19 in the above manner, the folding plates 19 can be adapted to packaging boxes of different sizes.
