Description

Technical Field

[0001] The utility model relates to the technical field of box-making machines, in particular to a double-station box-holding device. Background Art

[0002] In the existing patents, the Chinese patent document with the application number 201921833261.6 discloses a double-station box surface paper forming machine, which includes a box-holding device. The box-holding angle aluminum of the box-holding device needs to be driven by a slide cylinder to move along the 45° direction, and the two groups of box-holding moving frames on each guide rail seat move synchronously back and forth under the drive of a synchronous belt, so that the two groups of box-holding moving frames cannot work independently.

[0003] In addition, the Chinese patent document with the application number 201920884898.1 discloses a box-holding transfer mechanism. The first box-holding component and the second box-holding component move synchronously under the drive of a first moving drive device, and they also cannot work independently. Moreover, both the first box-holding block and the second box-holding block need to be controlled by a drive cylinder to move along the 45° direction. Content of the Utility Model

[0004] In order to solve the above technical problems, the purpose of the utility model is to provide a double-station box-holding device.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A double-station box-holding device includes a mounting frame and two box-holding mechanisms symmetrically arranged on the mounting frame. The box-holding mechanism includes a longitudinal box-holding drive mechanism mounted on the mounting frame and two relatively arranged box-holding modules. The longitudinal box-holding drive mechanism is used to drive the two box-holding modules to approach or move away from each other. The box-holding module includes a longitudinal moving plate longitudinally slidably connected to the mounting frame and connected to an output end of the longitudinal box-holding drive mechanism, a transverse moving plate transversely slidably connected to the longitudinal moving plate, a transverse moving drive mechanism mounted on the longitudinal moving plate and used to drive the transverse moving plate to reciprocate, a lifting seat vertically arranged on the transverse moving plate, a lifting drive mechanism mounted on the transverse moving plate and used to drive the lifting seat to lift, two box-holding angle members transversely slidably connected to the lifting seat and relatively arranged, a transverse box-holding drive mechanism mounted on the lifting seat and used to drive the two box-holding angle members to approach or move away from each other, and a box-clamping component mounted on the outer side of the transverse moving plate.

[0007] Further, the longitudinal box-holding drive mechanism includes a first bidirectional lead screw horizontally rotatably connected to the mounting frame, two first moving nuts respectively threadedly connected to the positive thread section and the reverse thread section of the first bidirectional lead screw, and a first rotation driver mounted on the mounting frame and used to drive the first bidirectional lead screw to rotate. The longitudinal moving plates of the two box-holding modules are respectively fixedly connected to the two first moving nuts.

[0008] Further, the transverse movement driving mechanism includes a rack installed on one side of the transverse movement plate close to the longitudinal movement plate, a gear rotatably connected to the longitudinal movement plate and in transmission engagement with the rack, and a second rotation driver installed on the longitudinal movement plate and used to drive the gear to rotate.

[0009] Further, the lifting driving mechanism includes a lifting lead screw vertically rotatably connected to the transverse movement plate, a lifting nut threadedly connected to the lifting lead screw, and a third rotation driver installed on the transverse movement plate and used to drive the lifting lead screw to rotate. The lifting seat is fixedly connected to the lifting nut, and the lifting seat is slidably connected to the transverse movement plate in a lifting manner.

[0010] Further, the horizontal box clamping driving mechanism includes a second bidirectional lead screw horizontally rotatably connected to the lifting seat, two second moving nuts respectively threadedly connected to the positive thread section and the reverse thread section of the second bidirectional lead screw, and a fourth rotation driver installed on the lifting seat and used to drive the second bidirectional lead screw to rotate. The two box clamping angle members are respectively fixedly connected to the two second moving nuts.

[0011] Further, the box clamping assembly includes a connecting arm installed on the outer side of the transverse movement plate, a guiding seat installed at the free end of the connecting arm, a box clamping plate slidably connected to the guiding seat, and an elastic member elastically connected between the guiding seat and the box clamping plate.

[0012] Further, the guiding seat is provided with a guiding hole, a guiding rod is installed on the back surface of the box clamping plate, the guiding rod slidably penetrates through the guiding hole, and the elastic member is sleeved outside the guiding rod.

[0013] Advantages of the present utility model: In practical applications, the two box clamping mechanisms work independently without affecting each other. One box clamping mechanism performs a box clamping and conveying action to the left, and the other box clamping mechanism performs a box clamping and conveying action to the right to form a double-station box clamping and conveying. When the box clamping mechanism clamps the box, the longitudinal box clamping driving mechanism drives the two box clamping modules to approach each other. At the same time, the transverse box clamping driving mechanism drives the two box clamping corner members to approach each other. Under the coordinated cooperation of the longitudinal box clamping driving mechanism and the transverse box clamping driving mechanism, the box clamping corner members will move along a 45° direction, causing the four box clamping corner members of the box clamping mechanism to gradually approach the center until the four box clamping corner members tightly hold the four corners of the box body at the feeding station, and the box clamping components of the two box clamping modules clamp the box body after edge wrapping at the edge wrapping station. After the four box clamping corner members tightly hold the box body, the lifting driving mechanism drives the lifting seat to drive the box clamping corner members and the box body to lift, enabling the actions of picking up and placing the box body. Moreover, the transverse movement driving mechanism drives the transverse movement plate to move horizontally relative to the longitudinal movement plate, and the horizontally moving transverse movement plate drives the box clamping corner members to drive the tightly held box body and the box clamping components to drive the box body after edge wrapping to move horizontally, so as to realize the box clamping and feeding of the box body and the discharging of the box body after edge wrapping. The present utility model realizes double-station box clamping and conveying, improves the efficiency of box clamping and conveying, and since the four box clamping corner members are driven to tightly hold the four corners of the box body through the coordinated cooperation of the longitudinal box clamping driving mechanism and the transverse box clamping driving mechanism, it eliminates the need for the box clamping corner members in the prior art to be additionally provided with a cylinder control to move along a 45° direction, simplifies the structure, reduces the cost, and reduces the pipeline (the layout of air pipes).

[0021] For the convenience of understanding by those skilled in the art, the following further describes the present utility model in conjunction with embodiments and drawings. The content mentioned in the implementation manner does not limit the present utility model.

[0022] As Figures 1 to 5 shown, a double-station box clamping device provided by the present utility model includes a mounting frame 1 and two box clamping mechanisms 2 symmetrically arranged on the mounting frame 1. The box clamping mechanism 2 includes a longitudinal box clamping driving mechanism 3 installed on the mounting frame 1 and two relatively arranged box clamping modules 4. The longitudinal box clamping driving mechanism 3 is used to drive the two box clamping modules 4 to approach or move away from each other; the box clamping module 4 includes a longitudinal moving plate 5 slidably connected to the mounting frame 1 and connected to an output end of the longitudinal box clamping driving mechanism 3, a transverse moving plate 6 slidably connected to the longitudinal moving plate 5, a transverse moving driving mechanism 7 installed on the longitudinal moving plate 5 and used to drive the transverse moving plate 6 to reciprocate, a lifting seat 8 arranged vertically on the transverse moving plate 6, a lifting driving mechanism 9 installed on the transverse moving plate 6 and used to drive the lifting seat 8 to lift, two box clamping corner pieces 10 slidably connected transversely to the lifting seat 8 and relatively arranged, a transverse box clamping driving mechanism 11 installed on the lifting seat 8 and used to drive the two box clamping corner pieces 10 to approach or move away from each other, and a box clamping assembly 12 installed on the outer side of the transverse moving plate 6.

[0023] In practical applications, the two box holding mechanisms 2 work independently without affecting each other. One box holding mechanism 2 performs a box holding and conveying action to the left, and the other box holding mechanism 2 performs a box holding and conveying action to the right to form a double-station box holding and conveying. When the box holding mechanism 2 holds the box, the longitudinal box holding drive mechanism 3 drives the two box holding modules 4 to approach each other. At the same time, the transverse box holding drive mechanism 11 drives the two box holding corner members 10 to approach each other. Under the coordinated cooperation of the longitudinal box holding drive mechanism 3 and the transverse box holding drive mechanism 11, the box holding corner members 10 will move along a 45° direction, causing the four box holding corner members 10 of the box holding mechanism 2 to gradually approach the center until the four box holding corner members 10 tightly hold the four corners of the box body at the loading station, and the box clamping components 12 of the two box holding modules 4 clamp the box body after edge wrapping at the edge wrapping station. After the four box holding corner members 10 tightly hold the box body, the lifting drive mechanism 9 drives the lifting seat 8 together with the box holding corner members 10 and the box body to lift, enabling the action of picking up and placing the box body. Moreover, the transverse movement drive mechanism 7 drives the transverse movement plate 6 to move horizontally relative to the longitudinal movement plate 5, and the horizontally moving transverse movement plate 6 drives the box holding corner members 10 together with the tightly held box body and the box clamping components 12 together with the box body after edge wrapping to move horizontally, so as to realize the box holding and loading of the box body and the unloading of the box body after edge wrapping. The utility model realizes double-station box holding and conveying, improves the efficiency of box holding and conveying, and because the longitudinal box holding drive mechanism 3 and the transverse box holding drive mechanism 11 cooperate with each other to drive the four box holding corner members 10 to tightly hold the four corners of the box body, the need for the box holding corner members 10 in the prior art to be additionally provided with a cylinder control to move along a 45° direction is eliminated, the structure is simplified, the cost is reduced, and the pipeline (the layout of air pipes) is reduced.

[0024] In this embodiment, the longitudinal box-clamping driving mechanism 3 includes a first bidirectional lead screw 13 horizontally rotatably connected to the mounting frame 1, two first moving nuts 14 respectively threadedly connected to the positive-thread section and the reverse-thread section of the first bidirectional lead screw 13, and a first rotation driver 15 installed on the mounting frame 1 and used to drive the first bidirectional lead screw 13 to rotate. The longitudinal moving plates 5 of the two box-clamping modules 4 are respectively fixedly connected to the two first moving nuts 14; the transverse box-clamping driving mechanism 11 includes a second bidirectional lead screw 21 horizontally rotatably connected to the lifting seat 8, two second moving nuts 22 respectively threadedly connected to the positive-thread section and the reverse-thread section of the second bidirectional lead screw 21, and a fourth rotation driver 23 installed on the lifting seat 8 and used to drive the second bidirectional lead screw 21 to rotate. The two box-clamping corner members 10 are respectively fixedly connected to the two second moving nuts 22. In practical applications, the first rotation driver 15 drives the first bidirectional lead screw 13 to rotate, and the rotating first bidirectional lead screw 13 drives the two first moving nuts 14 to move closer to or away from each other, so that the longitudinal moving plates 5 of the two box-clamping modules 4 move closer to or away from each other, thereby making the box-clamping corner members 10 of the two box-clamping modules 4 move closer to or away from each other. At the same time, the fourth rotation driver 23 drives the second bidirectional lead screw 21 to rotate, and the rotating second bidirectional lead screw 21 drives the two second moving nuts 22 to move closer to or away from each other, so that the two box-clamping corner members 10 on the box-clamping module 4 move closer to or away from each other, so that the four box-clamping corner members 10 approach or move away from each other along the 45° direction, thereby realizing clamping or loosening of the box body. The longitudinal box-clamping driving mechanism 3 and the transverse box-clamping driving mechanism 11 with this structural design make the box-clamping action smoother and not easily damage the box body.

[0025] In this embodiment, the transverse movement driving mechanism 7 includes a rack 16 installed on one side of the transverse movement plate 6 close to the longitudinal movement plate 5, a gear rotatably connected to the longitudinal movement plate 5 and in transmission engagement with the rack 16, and a second rotation driver 17 installed on the longitudinal movement plate 5 and used to drive the gear to rotate. In practical applications, the second rotation driver 17 drives the gear to rotate, and the rotating gear is in transmission engagement with the rack 16 to drive the rack 16 to reciprocate horizontally, and the reciprocating horizontally moving rack 16 drives the transverse movement plate 6 to reciprocate horizontally relative to the longitudinal movement plate 5, so as to complete the transfer action. The transverse movement driving mechanism 7 has a compact structure and occupies a small space.

[0026] In this embodiment, the lifting driving mechanism 9 includes a lifting lead screw 18 vertically rotatably connected to the transverse movement plate 6, a lifting nut 19 threadedly connected to the lifting lead screw 18, and a third rotation driver 20 installed on the transverse movement plate 6 and used to drive the lifting lead screw 18 to rotate. The lifting seat 8 is fixedly connected to the lifting nut 19, and the lifting seat 8 is slidably connected to the transverse movement plate 6 in a lifting manner. In practical applications, the third rotation driver 20 drives the lifting lead screw 18 to rotate, and the rotating lifting lead screw 18 drives the lifting nut 19 to move up and down, and the lifting nut 19 moving up and down drives the lifting seat 8 to move up and down.

[0027] In this embodiment, the clamping box assembly 12 includes a connecting arm 24 installed on the outer side of the transverse moving plate 6, a guiding seat 25 installed at the free end of the connecting arm 24, a clamping box plate 26 slidably connected to the guiding seat 25, and an elastic member 27 elastically connected between the guiding seat 25 and the clamping box plate 26. Specifically, the elastic member 27 is a spring. In practical applications, the clamping box assemblies 12 of the two box holding modules 4 cooperate to clamp the box body. When clamping the box body, the elastic member 27 not only plays a role in buffering and protecting, but also can provide a certain elastic force to the clamping box plate 26, so that the clamping box plate 26 can firmly clamp the box body.

[0028] In this embodiment, the guiding seat 25 is provided with a guiding hole, a guiding rod is installed on the back surface of the clamping box plate 26, the guiding rod slidably penetrates through the guiding hole, and the elastic member 27 is sleeved outside the guiding rod. By the sliding fit between the guiding rod and the guiding hole, the working stability of the clamping box plate 26 is improved.

[0029] Specifically, the first rotation driver 15, the second rotation driver 17, the third rotation driver 20, and the fourth rotation driver 23 can all adopt servo motors.

[0030] All the technical features in this embodiment can be freely combined according to actual needs.

[0031] The above embodiments are the preferred implementation solutions of the present utility model. In addition, the present utility model can also be implemented in other ways. Any obvious replacement without departing from the concept of the technical solution is within the protection scope of the present utility model.
