Description

Technical Field

[0001] The utility model relates to the technical field of honeycomb paperboard bending, in particular to a honeycomb paperboard bending mechanism. Background Art

[0002] Honeycomb cardboard consists of an inner core and facing panels pasted on both sides of the inner core. The inner core is provided with a plurality of regular polygonal holes. Therefore, it has stronger impact resistance than corrugated cardboard boxes and is widely used in outer packaging boxes of important equipment.

[0003] After the honeycomb paperboard is produced, it often needs to be bent into shape with the help of bending equipment. This not only makes it convenient for operators to directly process and shape the honeycomb paperboard and sell the finished products, but also can form indentations on the honeycomb paperboard, making it easier for users to splice and assemble it themselves later.

[0004] The existing honeycomb paperboard bending mechanism is generally separated from the feeding mechanism and the limiting mechanism, that is, the operator needs to use the feeding mechanism to push the honeycomb paperboard to make a linear motion first to ensure that the limiting mechanism corresponds to the expected indentation. After that, the operator uses the limiting mechanism to limit the honeycomb paperboard. At this time, the operator can apply pressure on one side of the honeycomb paperboard to complete the bending operation.

[0005] However, although the method of separating the feeding mechanism from the limiting mechanism has a wider processing range and can meet the bending requirements of different positions, the operation steps are cumbersome for the operator and the processing time is long, which is very uneconomical for large-scale repeated processing. Therefore, we believe that a honeycomb cardboard bending mechanism is needed that can bend at a fixed length and reduce the operation steps and processing time. Summary of the invention

[0006] In view of the deficiencies in the prior art, the utility model proposes a honeycomb paperboard bending mechanism, which has the advantages of reducing the operating steps, reducing the processing time, and reducing the cost of large-scale repeated production, and solves the shortcomings of the prior art devices of having many operating steps and long processing time.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] The camshaft is an axially movable shaft, and the camshaft is actuated to move the two ends of the camshaft together to form a rotation axis, and the camshaft is an axially movable shaft, and the camshaft is located above the left side of the camshaft.

[0009] Preferably, a slide groove is provided at the upper end of the mounting frame, and the movable shaft is inserted into the slide groove and is slidably connected to the mounting frame.

[0010] Preferably, a driving ring with an elliptical structure projected on the vertical plane is respectively sleeved on the two axial ends of the movable shaft, the driving ring is fixedly connected to the movable shaft, a rubber ring is fixedly connected in each of the slide grooves, the major axis length of the driving ring is greater than the longitudinal height of the inner cavity of the rubber ring, and the minor axis length of the driving ring is less than the longitudinal height of the inner cavity of the rubber ring.

[0011] Preferably, the front and rear ends of the driving plate are respectively fixedly connected with a follower plate, the follower plate is penetrated by a through hole, and the movable shaft is inserted into the through hole.

[0012] Preferably, an anti-skid ring is sleeved on the outer side of the movable shaft, the anti-skid ring is fixedly connected to the movable shaft, and transverse anti-skid grooves are provided on the anti-skid ring.

[0013] Preferably, a support plate and a bending plate are respectively provided at the lower end of the right side of the honeycomb paperboard from left to right, wherein the support plate is fixedly connected to the support frame, the left end of the bending plate is rotatably connected to the support frame, a pressure plate is provided at the upper end of the support plate, and positioning pins are respectively fixedly connected to the front and rear ends of the pressure plate, and the positioning pins are slidably connected to the mounting plate.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] The utility model drives the rack and the driving plate to move through the mounting frame, and utilizes the meshing transmission connection between the rack and the driving gear, and the transmission connection between the driving gear and the driven gear, so that the mounting frame synchronously drives the honeycomb paperboard to move and the limit plate to rotate during the movement process. At this time, combined with the change of friction resistance between the limit plate and the honeycomb paperboard during the rotation process, the limit plate can be used to apply strong resistance to the honeycomb paperboard during the movement of the mounting frame, that is, the honeycomb paperboard. At this time, the honeycomb paperboard can be constrained from moving, and the contact portion of the honeycomb paperboard with the limit plate can be prevented from moving upward. At this time, the user can realize the fixed-length bending of the honeycomb paperboard. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0023] Please refer to Figure 1-4 A honeycomb paperboard 4 bending mechanism includes a support frame for carrying the honeycomb paperboard 4, the support frame includes an outer frame, and a plurality of rollers arranged in parallel from left to right inside the outer frame, the plurality of rollers are rotatably connected to the outer frame, and the device constrains the honeycomb paperboard 4 to be arranged above the rollers and abut against the rollers, so that the rollers provide sufficient support for the honeycomb paperboard 4 while avoiding large friction between the honeycomb paperboard 4 and the support frame during the rightward movement, and the small friction reduces the burden on the operator, and can also avoid the friction causing the surface decorative paper of the honeycomb paperboard 4 to be damaged, affecting the state of the honeycomb paperboard 4.

[0024] Specifically, the device is provided with a driving plate 1 with a vertical surface of an inverted L-shaped structure at the upper left end of the honeycomb paperboard 4, which constrains the right end face of the vertical section of the driving plate 1 to abut against the left end face of the honeycomb paperboard 4. In this way, when the driving plate 1 moves to the right, the position constraint of the honeycomb paperboard 4 by the roller can drive the honeycomb paperboard 4 to move to the right through the driving plate 1.

[0025] Specifically, a slide rail 6 is respectively provided on the front and rear sides of the support frame. It should be noted that in practice, the device is installed above a workbench. The existence of the workbench is to ensure that the processing height is ergonomic and to accommodate and support the remaining components. In order to highlight the main components in this device, the workbench-related structure is omitted. However, it should be known that in practice, the support frame and the slide rail 6 are fixedly connected to the fixed workbench.

[0026] Specifically, the slide rail 6 is a U-shaped structure, and the U-shaped openings of the two slide rails 6 are opposite to each other.

[0027] Therefore, the mounting frame 3 arranged on the side close to the two slide rails 6 can be inserted into the U-shaped opening of the corresponding slide rail 6 through the corresponding plate-like structure on the side far from the two mounting frames 3, thereby achieving the purpose of sliding connection between the mounting frame 3 and the slide rail 6, and the mounting frame 3 is constrained by the slide rail 6 to only perform left and right linear motion.

[0028] Therefore, the device is provided with a movable shaft 2 between the two mounting frames 3, and the movable shaft 2 is constrained to be movably connected with the mounting frame 3 and the driving plate 1 respectively. The movable shaft 2 can be used to simultaneously drive the mounting frame 3 and the driving plate 1 to move to the right. At this time, the position constraint of the slide rail 6 on the mounting frame 3, that is, the position constraint of the slide rail 6 on the driving plate 1, can ensure that the driving plate 1 is always in abutment with the honeycomb paperboard 4.

[0029] Specifically, in the device, a rotating shaft 19 is rotatably connected to the upper right end of the honeycomb paperboard 4 through a mounting plate, the mounting plate is fixedly connected to the support frame, and the mounting plate is rotatably connected to the rotating shaft 19 .

[0030] A limiting plate 7 is disposed on the outer sleeve of the rotating shaft 19 . The limiting plate 7 is fixedly connected to the rotating shaft 19 , and the limiting plate 7 is rotatably connected to the supporting seat 5 .

[0031] At this time, by rotating the limit plate 7 and changing the distance between the lower end of the limit plate 7 and the honeycomb cardboard 4, the limit plate 7 can be used to constrain the position of the honeycomb cardboard 4 to ensure that the honeycomb cardboard 4 cannot withstand greater resistance and cannot move to the right. At the same time, the honeycomb cardboard 4 on the left and right sides of the limit plate 7 can be separated, so that when the user provides an upward thrust to the right side of the honeycomb cardboard 4, the part of the honeycomb cardboard 4 located on the right side of the limit plate 7 can be bent relative to the part of the honeycomb cardboard 4 located on the left side of the limit plate 7.

[0032] Furthermore, the device is provided with a pressing plate 17 at the lower side of the limiting plate 7, and the lower end surface of the pressing plate 17 abuts against the honeycomb paperboard 4, which makes the limiting plate 7 press the pressing plate 17 to move downward to constrain the position of the honeycomb paperboard 4 during rotation. This uses the pressing plate 17 instead of the limiting plate 7 to constrain the position of the honeycomb paperboard 4, which can avoid the structural damage to the honeycomb paper core inside the honeycomb paperboard 4 caused by the width problem of the limiting plate 7 itself.

[0033] Furthermore, the device is provided with a support plate 18 at the lower end of the pressing plate 17 to constrain the support seat 5 to be fixedly connected to the support plate 18, thereby providing an upward support force for the honeycomb paperboard 4 to prevent the pressing plate 17 from pressing down and damaging the honeycomb paperboard 4.

[0034] Furthermore, the device is provided with a bending plate 20 on the right side of the support plate 18, which constrains the bending plate 20 to be fixedly connected to the support seat 5. The bending plate 20 can increase the range of external force applied to the honeycomb paperboard 4, avoid deformation of the honeycomb paperboard 4 at a single point, ensure the overall force on the right side of the honeycomb paperboard 4, and minimize damage to the inner core of the honeycomb paperboard 4.

[0035] Specifically, a through slot is provided on the mounting plate, and positioning pins are fixedly connected to the front and rear ends of the pressing plate 17, and the positioning pins are inserted into the through slot so that the pressing plate 17 can only move up and down relative to the supporting seat 5, thereby ensuring that the fold position of the honeycomb paperboard 4 is fixed by the pressing plate 17.

[0036] Specifically, in order to control the rotation range of the limit plate 7, the device has driven gears 16 coaxially fixedly connected to the two axial ends of the movable shaft 2, and the rotation of the driven gears 16 drives the rotating shaft 19 to rotate.

[0037] Furthermore, the device is fixedly connected to a rack 11 on the right side of each mounting frame 3, and a front-to-rear axial driving gear 8 is meshed and transmission-connected to the upper end of each rack 11. The driving gear 8 is rotationally connected to the slide rail 6 through a fixed plate 9, and constrains the driving gear 8 to be rotationally connected to the slide rail 6. The driving gear 8 is transmission-connected to the driven gear 16. Therefore, when the user pushes the mounting frame 3 to the right to drive the rack 11 to rotate, the rotation amplitude of the driven gear 16, that is, the limit plate 7, can be synchronously controlled.

[0038] At the same time, in order to adjust the relationship between the moving distance of the mounting frame 3 and the rotation angle of the limit plate 7, the device also provides a reduction gear set 10 between the driving gear 8 and the driven gear 16, and the transmission ratio between the driving gear 8 and the driven gear 16 is adjusted by the reduction gear set 10.

[0039] It should be noted that due to the interaction force between the pressure plate 17 and the honeycomb paperboard 4, the maximum rotation angle of the limit plate 7 is limited. Therefore, the driving gear 8 connected to the driven gear 16 can only rotate a limited number of times, that is, the maximum length of a single rightward movement of the mounting frame 3 is limited. This maximum length can be regarded as the length of the fixed-length bend under normal conditions.

[0040] It should be noted that, in practice, when the user moves the mounting frame 3 to the right so that the pressure plate 17 abuts against the limit plate 7 and the mounting frame 3 cannot continue to move to the right, the user uses the bending plate 20 to achieve the bending of the honeycomb paperboard 4. Later, when it is necessary to continue bending another honeycomb paperboard 4, the user needs to replace the honeycomb paperboard 4. At the same time, the user needs to move the mounting frame 3 to the left to achieve the reset of the mounting frame 3. This reset distance can be constrained by setting a corresponding blocking mechanism in the slide rail 6. For example, the right side of the constrained slide rail 6 is a closed structure, and a corresponding blocking protrusion is set on the right side of the slide rail 6. By constraining the reset distance and cooperating with the limit plate 7, the device can achieve the purpose of fixed-length bending by moving the mounting frame 3.

[0041] Furthermore, in order to adapt to honeycomb cardboards 4 of different lengths and ensure that the device can achieve fixed-length bending for honeycomb cardboards 4 of multiple lengths, the device is provided with a slide groove 15 at the upper end of the mounting frame 3, and the movable shaft 2 is constrained to be inserted into the slide groove 15, so that the movable shaft 2 can move left and right relative to the mounting frame 3. At this time, when facing honeycomb cardboards 4 of different lengths, the user can change the movable shaft 2, that is, the position of the driving plate 1, so that the position of the driving plate 1 matches the left end face of the honeycomb board.

[0042] Furthermore, the device is provided with a driving ring 13 with a vertical plane projection as an elliptical structure on the two axial ends of the movable shaft 2, the driving ring 13 is fixedly connected to the movable shaft 2, and a rubber ring 14 is fixedly connected in each slide groove 15, the major axis length of the driving ring 13 is greater than the longitudinal height of the inner cavity of the rubber ring 14, and the minor axis length of the driving ring 13 is less than the longitudinal height of the inner cavity of the rubber ring 14, so that when the driving ring 13 and the rubber ring 14 are interference fit, the user can push the movable shaft 2 to drive the mounting frame 3 to move left and right, and when the driving ring 13 and the rubber ring 14 are clearance fit, the user can change the position of the movable shaft 2 alone.

[0043] Therefore, the device is fixedly connected to a follower plate at the front and rear ends of the driving plate 1 respectively, and a through hole is penetrated through the follower plate to constrain the movable shaft 2 to be inserted into the through hole to realize the rotational connection between the movable shaft 2 and the driving plate 1, so that the movable shaft 2 can drive the driving plate 1 to move left and right, and the driving plate 1 cannot hinder the rotation of the movable shaft 2 to change the matching relationship between the driving ring 13 and the rubber ring 14.

[0044] Therefore, in order to facilitate the rotation of the movable shaft 2, the device is provided with an anti-skid ring 12 on the outer side of the movable shaft 2, the anti-skid ring 12 is constrained and fixedly connected to the movable shaft 2, and the anti-skid ring 12 is provided with transverse anti-skid grooves.

[0045] In actual use, the utility model:

[0046] First, the user rotates the movable shaft 2 so that the drive ring 13 and the rubber ring 14 are loosely matched. At this time, the movable shaft 2 is moved so that the right end surface of the vertical section of the drive plate 1 abuts against the left end surface of the honeycomb paperboard 4.

[0047] Then, the movable shaft 2 is pushed rightward to drive the driving plate 1 to move rightward. At this time, the honeycomb paperboard 4 moves rightward for the first time.

[0048] Afterwards, the movable shaft 2 is rotated to make the driving ring 13 and the rubber ring 14 have an interference fit. At this time, the movable shaft 2 is pushed to drive the driving plate 1 and the mounting frame 3 to move rightward. At this time, the honeycomb paperboard 4 moves rightward for the second time.

[0049] Finally, the movable shaft 2 is continuously pushed to the right until the limit plate 7 abuts against the pressure plate 17, and the pressure plate 17 cooperates with the resistance between the support plate 18 and the honeycomb paperboard 4 to force the honeycomb paperboard 4 to be unable to move to the right. At this time, the rotating bending plate 20 completes the bending process.

[0050] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
