Description

Technical Field

[0001] This utility model relates to a mold structure for forming paper boxes. Background Technology

[0002] Cardboard box forming relies on forming molds (referred to as molds). For example, in a stapling machine, the mold is a vertical lifting mold. After the mold descends, it presses onto the cardboard below, which then surrounds the mold. The stapling device then joins the cardboard together to form the box, after which it is demolded and raised back up. Because cardboard box dimensions vary, molds of corresponding sizes are required. For small (length and width) cardboard boxes, the entire mold can be replaced. However, for larger cardboard boxes, replacing the entire mold is not only inconvenient but also costly, and the replacement and disassembly process is cumbersome. Utility Model Content

[0032] 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 implementation of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0033] Referring to the accompanying drawings, in this embodiment, a vertical lifting mold for forming a paper box includes a mold assembly 1 mounted on a frame 9. The mold assembly 1 includes a left front mold 11, a right front mold 12, a left rear mold 13, and a right rear mold 14 located at four corners. The left front mold 11, right front mold 12, left rear mold 13, and right rear mold 14 are located at four corners and cooperate to form the mold assembly 1 for forming paper boxes. Typically, the paper box has a square body.

[0034] The frame 9 is also equipped with longitudinal adjustment plates 2 arranged in a front-to-back manner. The longitudinal adjustment plates 2 at the front and the longitudinal adjustment plates 2 at the rear are arranged in a front-to-back manner, and the longitudinal adjustment plates 2 can be moved longitudinally on the frame 9 to adjust their front and rear positions.

[0035] Each longitudinal adjustment plate 2 is provided with a transverse adjustment frame 3 arranged opposite to each other. That is, each longitudinal adjustment plate 2 has a transverse adjustment frame 3 on the left and a transverse adjustment frame 3 on the right. The transverse adjustment frame 3 on the left and the transverse adjustment frame 3 on the right are arranged opposite to each other. The transverse adjustment frame 3 can move laterally on the longitudinal adjustment plate 2 to adjust its left and right position.

[0036] Each transverse adjustment frame 3 is equipped with a corresponding lifting mold base 4, that is, each transverse adjustment frame 3 has a lifting mold base 4, and the lifting mold base 4 can move up and down on the transverse adjustment frame 3.

[0037] The left front mold 11, right front mold 12, left rear mold 13 and right rear mold 14 are respectively installed on the corresponding lifting mold base 4 and located at the lower part of it (lifting mold base 4).

[0038] Its working principle is as follows: The longitudinal adjustment plate 2 (set in opposite directions) moves longitudinally to adjust its front and rear positions. The longitudinal longitudinal positions of the transverse adjustment frame 3 and the lifting mold base 4 (and the corresponding mold below) on the longitudinal adjustment plate 2 are also adjusted. The transverse adjustment frame 3 (set in opposite directions) moves laterally on the longitudinal adjustment plate 2 to adjust its left and right positions. The transverse adjustment frame 4 (and the corresponding mold below) on the transverse adjustment frame 3 is also adjusted. Finally, the front, rear, left and right positions of the left front mold 11, right front mold 12, left rear mold 13 and right rear mold 14, which are distributed at the four corners, are adjusted accordingly. They are adjusted to the required positions to meet the forming requirements of different (length and width) size paper boxes. The left front mold 11, right front mold 12, left rear mold 13 and right rear mold 14 can also be lifted and lowered accordingly, for example, for the forming requirements of a nailing machine.

[0039] This vertical lifting mold for paper box forming includes a mold assembly 1 comprising a left front mold 11, a right front mold 12, a left rear mold 13, and a right rear mold 14 distributed at the four corners. By adjusting the relative positions of the left front mold 11, right front mold 12, left rear mold 13, and right rear mold 14, and by meeting the lifting operation requirements, it can meet the forming needs of paper boxes of different (length and width) sizes, realizing the adjustable mold specification function. This adjustable method can meet the forming needs of paper boxes with relatively large length and width sizes without replacing the mold assembly 1, making it relatively convenient to use. Within a certain specification range, only the position needs to be adjusted to meet the requirements. It is particularly suitable for small-batch paper box forming production, avoiding the problem of frequent disassembly and replacement of molds due to changes in paper box specifications, and reducing production costs.

[0040] Based on the above embodiments, the following optimizations or further explanations can be made.

[0041] For example, the longitudinal adjustment plate 2 is connected to the longitudinal adjustment drive mechanism 5, which drives the longitudinal adjustment plate 2 to move longitudinally on the frame 9 to adjust its front and rear positions.

[0042] For example, the transverse adjustment frame 3 is connected to the transverse adjustment drive mechanism 6, which in turn drives the transverse adjustment frame 3 to move laterally on the longitudinal adjustment plate 2 to adjust its left and right positions.

[0043] For example, the lifting mold base 4 is connected to a lifting and running drive mechanism 7, which drives the lifting mold base 4 to move up and down on the transverse adjustment frame 3 to cooperate with the paper box forming process.

[0044] For example, the longitudinal shifting and positioning drive mechanism 5 includes a longitudinal shifting and positioning drive motor 50; the frame 9 is provided with a longitudinal guide rail 91, the longitudinal shifting and positioning plate 2 is connected to the longitudinal guide rail 91 on the frame 9, and the longitudinal shifting and positioning plate 2 can move stably back and forth longitudinally along the longitudinal guide rail 91. Alternatively, a linkage transmission method that adjusts both the front and rear simultaneously can be adopted. For example, the longitudinal shifting and positioning drive mechanism 5 also includes a first forward and reverse bidirectional lead screw 51, a first positive thread lead screw 52, ​​and a first negative thread lead screw 53. The first forward and reverse bidirectional lead screw 51 (i.e., a forward and reverse thread bidirectional lead screw, which can be an integral structure or a separate and reconnected structure) is arranged longitudinally, that is, one end of the first forward and reverse bidirectional lead screw 51 faces forward and the other end faces backward. The longitudinal shifting and positioning drive motor 50 is mounted on the frame 9. The first forward and reverse bidirectional lead screw 51 is connected and configured on the frame 9. A first support base 54 can be set on the frame 9. The first forward and reverse bidirectional lead screw 51 is configured on the first support base 54, and the first support base 54 cooperates to support the rotation of the first forward and reverse bidirectional lead screw 51. The longitudinal shifting and positioning drive motor 50 is connected to the first forward and reverse bidirectional lead screw 51 through transmission. The longitudinal shifting and positioning drive motor 50 (such as a servo motor, etc.) drives the first forward and reverse bidirectional lead screw 51 to rotate (forward and reverse). The first positive thread nut 52 and the first negative thread nut 53 are respectively set on the longitudinal adjustment plate 2 arranged in opposite directions. For example, the first positive thread nut 52 is set on the front longitudinal adjustment plate 2 and the first negative thread nut 53 is set on the rear longitudinal adjustment plate 2. The two ends of the first positive and negative bidirectional screw 51 are respectively connected to the first positive thread nut 52 and the first negative thread nut 53. When the first positive and negative bidirectional screw 51 rotates, it will drive the longitudinal adjustment plate 2 arranged in opposite directions to move closer or separate on the frame 9 through the cooperation of the first positive thread nut 52 and the first negative thread nut 53, so as to realize the adjustment of the longitudinal front and rear position. The transverse adjustment frame 3 (and the lifting mold base 4, etc.) arranged in opposite directions on the longitudinal adjustment plate 2 are also adjusted in the longitudinal front and rear position. The longitudinal front and rear positions (i.e. front and rear distances) between the left front mold 11 and the left rear mold 13, and the right front mold 12 and the right rear mold 14 can be adjusted together, which is more convenient. In addition, two first positive and negative bidirectional lead screws 51 can be arranged on the left and right sides of the frame 9 and can be connected by chain or shaft for transmission, making the longitudinal adjustment plate more stable and balanced in longitudinal adjustment.

[0045] For example, the transverse adjustment drive mechanism 6 includes a transverse adjustment drive motor 60; each longitudinal adjustment plate 2 is provided with a transverse guide rail 61, and each transverse adjustment frame 3 is connected to the corresponding transverse guide rail 61 so that the transverse adjustment frame 3 can move and adjust stably left and right along the transverse guide rail 61 on the longitudinal adjustment plate 2. Alternatively, a linkage transmission method that adjusts both left and right simultaneously can be adopted. The transverse adjustment drive mechanism 6 also includes a second bidirectional lead screw 62, a second positive thread nut 63, and a second negative thread nut 64. The second bidirectional lead screw 62 (i.e., a bidirectional lead screw with both positive and negative threads, which can be an integral structure or a separate and reconnected structure) is set on the longitudinal adjustment plate 2. The second bidirectional lead screw 62 is arranged laterally, that is, one end of the second bidirectional lead screw 62 faces left and the other end faces right. The second bidirectional lead screw 62 is connected to the transverse adjustment drive motor 60 (such as a servo motor), and the transverse adjustment drive motor 60 drives the second bidirectional lead screw 62 to rotate (in both directions). The second positive thread nut 63 and the second negative thread nut 64 are respectively set on the left and right opposite sides of the transverse adjustment plate 2. The two ends of the second positive and negative bidirectional lead screw 62 are connected to the shifting frame 3. For example, a second positive thread nut 63 is set on the left transverse shifting frame 3, and a second negative thread nut 64 is set on the right transverse shifting frame 3. When the second positive and negative bidirectional lead screw 62 rotates, it will respectively drive the second positive thread nut 63 and the second negative thread nut 64 to move the transverse shifting frames 3 (on the same longitudinal shifting plate 2) that are set up opposite each other to move closer together or separate, so as to realize the adjustment of the transverse left and right position. The lifting mold base 4 (and the corresponding mold below it) on the transverse shifting frame 3 set up opposite each other can also adjust the transverse left and right position. The transverse left and right position (i.e., the left and right distance) between the left front mold 11 and the right front mold 12, and the left rear mold 13 and the right rear mold 14 can be adjusted, which is relatively more convenient.

[0046] In this design, a transverse adjustment drive motor 60 is mounted on a longitudinal adjustment plate 2. A second support base 65 is mounted on the longitudinal adjustment plate 2, and a second bidirectional lead screw 62 is mounted on the second support base 65, which supports the rotation of the second bidirectional lead screw 62. Furthermore, the second bidirectional lead screws 62 on the longitudinal adjustment plates 2, which are arranged opposite each other, can be interconnected for transmission. This allows the transverse adjustment frame 3 on the longitudinal adjustment plates 2 to be adjusted simultaneously (generally synchronously) when adjusting its lateral left and right position (i.e., left and right distance), making the adjustment more convenient. Two second bidirectional lead screws 62 can be distributed front and back on each longitudinal adjustment plate 2, and can be connected by chains or shafts for transmission, resulting in smoother and more balanced transverse adjustment of the transverse adjustment frame.

[0047] For example, a front bevel gear 66 is provided on the second forward and reverse bidirectional lead screw 62, and the front bevel gear 66 meshes with a front auxiliary bevel gear 661 (mutual transmission). A rear bevel gear 67 is provided on the second forward and reverse bidirectional lead screw 62, and the rear bevel gear 67 meshes with a rear auxiliary bevel gear 671 (mutual transmission). The front auxiliary bevel gear 661 and the rear auxiliary bevel gear 671 are connected by a linkage shaft 68 (achieving linkage). The linkage shaft 68 is arranged longitudinally (one end facing forward and the other end facing backward). The front auxiliary bevel gear 661 and the rear auxiliary bevel gear 671 are connected by a linkage shaft 68. The transmission sleeve 71 is connected to the linkage shaft 68 to drive rotation, and at least one of the (front auxiliary bevel gear 661 and rear auxiliary bevel gear 671) is longitudinally slidable relative to the linkage shaft 68. That is, at least one of the front auxiliary bevel gear 661 and the rear auxiliary bevel gear 671 can slide longitudinally on the linkage shaft 68. For example, the axis of at least one of the front auxiliary bevel gear 661 and the rear auxiliary bevel gear 671 is provided with a spline hole / hexagonal hole, and the linkage shaft 68 is provided with a spline shaft / hexagonal bar. The spline hole / hexagonal hole is sleeved on the spline shaft / hexagonal bar to form a longitudinal sliding structure. The linkage shaft 68 can not only connect the front auxiliary bevel gear 661 and the rear auxiliary bevel gear 671 to drive them to rotate together, but also, through the longitudinal sliding structure, the distance between the front auxiliary bevel gear 661 and the rear auxiliary bevel gear 671 can be adjusted along with the front and rear distance of the longitudinal adjustment plate 2. In this structure, the longitudinal adjustment plates 2 can be adapted to each other during the longitudinal movement of the longitudinal adjustment plates 2 to adjust the front and rear positions (i.e., the front and rear distance). The longitudinal adjustment drive mechanism 5 and the transverse adjustment drive mechanism 6 will not interfere with each other and can operate smoothly.

[0048] For example, the front auxiliary bevel gear 661 is relatively fixedly connected to the linkage shaft 68 (it can be locked or held in place by fasteners), and the rear auxiliary bevel gear 671 is longitudinally slidably arranged relative to the linkage shaft 68 (e.g., the rear auxiliary bevel gear 671 has a splined hole / hexagonal hole, and the linkage shaft 68 has a splined shaft / hexagonal bar part, with the splined hole / hexagonal hole sleeved on the splined shaft / hexagonal bar to form a longitudinal sliding structure). For example, a front gear support seat 662 is provided on the front longitudinal adjustment plate 2, and the front auxiliary bevel gear 661 is set on the front gear support seat 662; a rear gear support seat 672 is provided on the rear longitudinal adjustment plate 2, and the rear auxiliary bevel gear 671 is set on the rear gear support seat 672. The corresponding support seats (usually containing bearings) are used to cooperate in supporting the rotation of the corresponding components (such as the front auxiliary bevel gear 661 and the rear auxiliary bevel gear 671).

[0049] For example, the lifting drive mechanism 7 includes a lifting drive motor 70; the lifting drive mechanism 7 includes a synchronous rotating shaft 71; the lifting drive motor 70 (such as a servo motor) is mounted on the frame 9, and the synchronous rotating shaft 71 is connected to the frame 9. The lifting drive motor 70 and the synchronous rotating shaft 71 are connected in a transmission connection, and the lifting drive motor 70 can drive the synchronous rotating shaft 71 to rotate on the frame 9. The synchronous rotating shaft 71 is arranged longitudinally (one end of the synchronous rotating shaft 71 faces forward and the other end faces backward). The synchronous rotating shaft 71 is equipped with output bevel gears 72 arranged in opposite directions. The synchronous rotating shaft 71 drives the output bevel gears 72 to rotate together, and the output bevel gears 72... The synchronous rotating shaft 71 is longitudinally (i.e., front-to-back) slidably arranged relative to it (e.g., the output bevel gear has a splined hole / hexagonal hole, and the synchronous rotating shaft 71 has a splined shaft / hexagonal bar portion, with the splined hole / hexagonal hole fitting onto the splined shaft / hexagonal bar to form a longitudinal sliding structure). Each of the longitudinally shifting adjustment plates 2, arranged front-to-back, has a support seat 73. The output bevel gears 72, arranged front-to-back, are mounted on their respective support seats 73. The corresponding support seats 73 (usually containing bearings) are used to support the rotation of their respective components (e.g., the output bevel gears 72). The front output bevel gear 72 moves back and forth together with the front longitudinally shifting adjustment plate 2, and the rear output bevel gear 72 moves back and forth together with the rear longitudinally shifting adjustment plate 2. The front and rear output bevel gears 72 can respectively drive the synchronous drive shaft 74 on the front and rear longitudinally shifting adjustment plates 2 (which can move and adjust longitudinally) to rotate. The transverse adjustment frame 3, which is arranged opposite to each other, is equipped with drive wheels 75. The shaft holes of the left and right drive wheels 75 are fitted with synchronous drive shafts 74 for transmission connection. The synchronous drive shafts 74 will drive the left and right drive wheels 75 (on the longitudinal adjustment plate 2) to rotate together. The synchronous drive shafts 74 are arranged laterally (one end facing left and one end facing right), and the drive wheels 75 and the synchronous drive shafts 74 are arranged laterally (i.e., left and right). The drive wheels 75 can slide laterally on the corresponding synchronous drive shafts 74. For example, the shaft hole of the drive wheel 75 is a spline hole / hexagonal hole, and the synchronous drive shaft 74 is provided with a spline shaft / hexagonal bar. The spline hole / hexagonal hole is fitted on the spline shaft / hexagonal bar to form a transverse sliding structure, so as to meet the lifting transmission requirements of the lifting mold base 4 after the transverse adjustment frame 3 is arranged opposite to each other to adjust its position laterally. The synchronous drive shaft 74 is equipped with an input bevel gear 76, and an output bevel gear 72 is meshed with the input bevel gear 76 for transmission. The synchronous drive shaft 71 drives the output bevel gear 72 to rotate, the output bevel gear 72 drives the input bevel gear 76 to rotate, the input bevel gear 76 drives the synchronous drive shaft 74 to rotate, and the synchronous drive shaft 74 drives the drive wheel 75 to rotate. The drive wheel 75 on the transverse adjustment frame 3 is connected to the corresponding lifting mold base 4, and the drive wheel 75 drives the lifting mold base 4 to move up and down on the transverse adjustment frame 3. The support base 73 can also be additionally equipped with support components (such as bearings) to support the rotation of the synchronous drive shaft 74 and / or the input bevel gear 76 for greater stability.

[0050] The lifting mold base 4 is connected to the transverse adjustment frame 3 by a vertical guide rail 77. The lifting mold base 4 moves stably up and down along the vertical guide rail 77 on the transverse adjustment frame 3. There are many ways for the drive wheel 75 to drive the lifting mold base 4 to move up and down. For example, the drive wheel 75 can be a lifting drive gear. The lifting mold base 4 is equipped with a vertical rack 78. The lifting drive gear and the vertical rack 78 are meshed and connected. When the drive wheel 75 (lifting drive gear) rotates forward / reverse, it drives the vertical rack 78 and the lifting mold base 4 to move up and down.

[0051] In addition, the mold assembly 1 can also be equipped with some auxiliary components to assist in the molding of paper boxes. For example, auxiliary support components (such as auxiliary support templates) can be added between the left front mold 11 and the left rear mold 13, and between the right front mold 12 and the right rear mold 14. The operation of adding these components based on the left front mold 11, the right front mold 12, the left rear mold 13, and the right rear mold 14 is relatively convenient. For example, between the left front mold 11 and the right front mold 12, and between the left rear mold 13 and the right rear mold 14, there are sliding plate assemblies 8 that slide relatively left and right. The sliding plate assembly 8 includes a left sliding plate 81 and a right sliding plate 82. A slider and a slide rail are respectively provided between the left sliding plate 81 and the right sliding plate 82 (to stabilize left and right sliding). A left and right sliding split-and-join adjustment drive device 80 is also provided between the left sliding plate 81 and the right sliding plate 82. For example, the left and right sliding split-and-join adjustment drive device 80 includes a split-and-join adjustment drive motor 83, and the sliding split-and-join adjustment drive device also includes an adjusting screw 84 and an adjusting nut 85. The adjusting screw 84 is arranged horizontally and is drivenly connected to the split-and-join adjustment drive motor 83 and the adjusting screw 84 is drivenly connected to the adjusting nut 85. The adjusting screw 84 and the split-and-join adjustment drive motor 83 are connected to one of the left sliding plate 81 and the right sliding plate 82, and the other is connected to The adjusting nut 85 is set; the sliding opening and closing adjustment drive device drives the left slide plate 81 and the rear slide plate to slide left and right (close and separate from each other); the horizontal adjustment frame 3 set on the left and right opposite each other moves left and right synchronously with the left slide plate 81 and the right slide plate 82. The horizontal adjustment frame 3 separates left and right synchronously with the left slide plate 81 and the right slide plate 82, and also moves closer to each other synchronously. The thread locking function of the adjusting screw 84 and the adjusting nut 85 without rotation can increase the stability and support effect between the left front mold 11 and the right front mold 12, and between the left rear mold 13 and the right rear mold 14. Especially in the process of paper box binding and forming such as stapling machine, the binding pressure is large. When binding from the left and right sides, if there is no support, the left front mold 11 and the right front mold 12, and the left rear mold 13 and the right rear mold 14 are easily moved by the external forces from the left and right sides, which affects the stability of forming and the paper box forming effect.
