Description

Technical Field

[0001] The utility model relates to the technical field of packaging box production and manufacturing, in particular to a packaging box positioning and clamping device. Background Art

[0002] A packaging box is a box used to package products. Its main function is to ensure the safety of products during transportation and to improve the grade of products.

[0003] Paper packaging boxes have a wide range of applications, such as wine boxes, shoe boxes, etc. In the production of paper packaging boxes, the packaging boxes are usually folded paper pieces after production, and then unfolded to form a three-dimensional packaging box. When performing other processing on the unfolded packaging boxes, the paper packaging boxes are easy to tilt, which makes the processing of the packaging boxes difficult. Therefore, a packaging box positioning and clamping device is used.

[0004] The existing patent document with authorization announcement number CN218749590U clamps and fixes the packaging box in the horizontal and vertical directions through a horizontal clamping and positioning component and a vertical pressing and positioning component. The packaging box is shaped under the clamping and fixing of the horizontal clamping and positioning component and the vertical pressing and positioning component to avoid tilting and twisting during processing. However, due to the limitation of the material of the packaging box, direct pressure is applied to the surface of the packaging box for squeezing and clamping. When the clamping force is too large, the packaging box will be deformed, affecting the accuracy of subsequent packaging box processing. For this reason, we provide a packaging box positioning and clamping device to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0022] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0023] As described in the background technology, due to the limitation of the material of the packaging box, directly applying pressure to the surface of the packaging box for squeezing and clamping may cause the packaging box to deform when the clamping force is too large, affecting the accuracy of subsequent packaging box processing. For this reason, this embodiment provides a packaging box positioning and clamping device.

[0024] See also Figures 1 to 4 This embodiment proposes a packaging box positioning and clamping device, including a processing table 1, a first cylinder 3 is installed on the upper surface of the processing table 1, and a push plate 4 is fixedly connected to the output end of the first cylinder 3, see Figure 1 It can be seen that a slide is provided on the upper surface of the processing table 1, which is connected to the processing station of the packaging box. When the first cylinder 3 is started, its output end is extended and retracted, which can drive the push plate 4 to move left and right, thereby pushing the packaging box along the slide to the processing station.

[0025] The upper surface of the processing table 1 is fixedly connected with a limit plate 12 , which is arranged at the processing station of the packaging box and can limit the packaging box to prevent the packaging box from slipping off the processing station.

[0026] A clamping mechanism 2 is disposed outside the processing table 1 . The clamping mechanism 2 includes a servo motor 201 and two clamping plates 207 . The servo motor 201 is fixedly connected to the processing table 1 . A screw rod 202 is fixedly connected to the output shaft end of the servo motor 201 .

[0027] The processing table 1 provides fixed support for the servo motor 201. After the servo motor 201 is started, it can drive the screw 202 to rotate forward and reversely. A control system is provided inside the servo motor 201. A power-off locking device is installed in the control system. When the power is disconnected, the power-off locking device will lock the rotor of the servo motor 201 in the current position to prevent the servo motor 201 from running. When the power is restored, the power-off locking device will be unlocked to allow the servo motor 201 to continue to run, thereby locking the position of the screw 202 after rotation.

[0028] The outer surface of the screw rod 202 is threadedly connected to a support frame 203 that is slidably connected to the processing table 1 . The inner wall of the support frame 203 is fixedly connected to two servo electric cylinders 204 . The output ends of the two servo electric cylinders 204 are fixedly connected to a fixing plate 205 .

[0029] After the screw 202 rotates, it can drive the support frame 203 to slide left and right along the outer surface of the processing table 1, and the support frame 203 drives the servo electric cylinder 204 to move left and right. After the servo electric cylinder 204 is started, its output end is extended and retracted, which can drive the fixed plate 205 to move forward and backward.

[0030] A first fixed block 7 is fixedly connected to the bottom surface of the processing table 1, and the first fixed block 7 is rotatably connected to the screw 202. The processing table 1 fixedly supports the first fixed block 7, thereby providing auxiliary support for the screw 202, making the screw 202 more stable during rotation, and avoiding jamming or swinging of the screw 202 during rotation.

[0031] The inner wall of the support frame 203 is slidably connected to two guide rods 8, and the outer surfaces of the two guide rods 8 are fixedly connected to second fixed blocks 9. Each second fixed block 9 is fixedly connected to the processing table 1. The processing table 1 fixedly supports the guide rods 8, and the guide rods 8 fixedly support the second fixed blocks 9. The second fixed blocks 9 can guide the movement of the support frame 203, making it more stable during the left and right movement.

[0032] A second cylinder 5 is installed on the inner top wall of the support frame 203, and a pressure plate 6 is fixedly connected to the output end of the second cylinder 5. When the second cylinder 5 is started, its output end is extended and retracted, which can drive the pressure plate 6 to move up and down, thereby pressing and positioning the top of the packaging box, further improving the stability of the positioning and clamping of the packaging box.

[0033] A control panel 13 is installed on the upper surface of the processing table 1. The control panel 13 is electrically connected to the servo motor 201. Both support frames 203 are electrically connected to the control panel 13. The control panel 13 can uniformly control the electrical components in the packaging box positioning and clamping device, thereby improving the convenience of using the packaging box positioning and clamping device.

[0034] The inner walls of the two fixed plates 205 are slidably connected with two sliding rods 206 , which are fixedly connected to the clamping plate 207 . The outer surface of each sliding rod 206 is sleeved with a return spring 208 , and the fixed plates 205 and the clamping plates 207 are fixedly connected to the return springs 208 .

[0035] After the fixed plate 205 moves, the clamping plate 207 is driven to move by the slide bar 206 and the return spring 208. When the packaging box is positioned and clamped, the clamping plate 207 first contacts the outer wall of the packaging box, and then the clamping plate 207 continues to approach the packaging box, which will compress the return spring 208 to cause it to produce elastic deformation, and at the same time make the slide bar 206 slide in the reserved hole of the fixed plate 205. Under the resetting action of the return spring 208, the clamping force is buffered to avoid deformation of the packaging box due to excessive clamping force, thereby avoiding affecting the accuracy of subsequent packaging box processing.

[0036] The two clamping plates 207 are fixedly connected to a protective pad 10 on one side close to each other. The protective pad 10 can be made of rubber or foam material to prevent the outer wall of the packaging box from being scratched during the clamping and fixing process. The outer surface of each sliding rod 206 is fixedly connected to a limiting block 11. The limiting block 11 can provide limiting support for the sliding rod 206 to prevent the sliding rod 206 from sliding out of the reserved hole on the fixing plate 205 when in use.

[0037] Working principle: When using the packaging box positioning and clamping device, move the packaging box to the processing station, adjust the position of the positioning and clamping device according to the size of the packaging box, control the servo motor 201 to start, which can drive the screw 202 to rotate. After the screw 202 rotates, it can drive the support frame 203 to slide along the outer surface of the processing table 1. The support frame 203 drives the servo electric cylinder 204 to move. After the servo electric cylinder 204 is started, its output end is extended and retracted, which can drive the fixed plate 205 to move. After the fixed plate 205 moves, the clamping plate 207 is driven to move through the slide bar 206 and the return spring 208, so that the two clamping plates 207 move to the center of the packaging box, and then the packaging box is positioned and clamped. The clamping plate 207 first contacts the packaging box. The outer wall contacts, and then the clamping plate 207 continues to approach the packaging box, which will compress the reset spring 208, causing it to produce elastic deformation, and at the same time make the slide bar 206 slide in the reserved hole of the fixed plate 205. Under the reset action of the reset spring 208, the clamping force is buffered to avoid the packaging box being deformed due to excessive clamping force. The utility model can adjust the position of the positioning clamp according to the size of the packaging box when positioning and clamping the packaging box, so that the position of the positioning clamp is located at the center of the packaging box, thereby improving the stability of the packaging box when positioning and clamping, and at the same time can buffer the positioning clamping force of the packaging box, avoid the packaging box being deformed due to excessive clamping force, thereby avoiding affecting the accuracy of subsequent packaging box processing.
