Description

Technical Field

[0001] This utility model relates to the field of case packing machine technology, and in particular to a gripping mechanism for a case packing machine. Background Technology

[0002] A case packer is a device that semi-automatically or automatically loads unpackaged or small-packaged products into transport packaging. Its working principle involves arranging and quantitatively loading products into boxes (corrugated cardboard boxes, plastic boxes, pallets) and then closing or sealing the openings. According to requirements, a case packer should have functions for box forming (or opening), weighing, and packing; some also include sealing or strapping functions.

[0003] In the prior art, Chinese patent application number 202323601597.9 discloses a gripping mechanism for a case packing machine, including a support frame. The bottom surface of the support frame is provided with a gripping mechanism and a clamping mechanism. A first hydraulic rod drives a first slider to move, which in turn drives the first support frame to move, thereby adjusting the position of the first support frame according to different materials. A third hydraulic rod drives a second slider and a fixed plate to move, thereby adjusting the height of the second support frame according to the height of different materials. A first motor drives a double-ended threaded rod to rotate, which drives two third sliders to move, which in turn drive a first baffle and a fixed column to move. A second hydraulic rod drives a fourth slider to deflect, thereby adjusting the angle of the inclined plate according to the size of different materials. A clamping plate is provided to clamp the materials, facilitating better material gripping operations of the case packing machine.

[0004] However, the above technical solution only has two clamping plates. If a large cylindrical bottle needs to be clamped for packing, it will lead to unstable clamping and possible detachment. The clamping applicability is poor. Therefore, this application proposes a gripping mechanism for a packing machine to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where only two clamping plates are provided. When clamping large cylindrical bottles for packing, the clamping becomes unstable and may detach, resulting in poor clamping applicability. Therefore, this invention proposes a gripping mechanism for a packing machine.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A gripping mechanism for a case packer includes a support, and the gripping mechanism further includes:

[0008] Mounting plate, the top of which is fixedly mounted to the bottom end of the bracket;

[0009] The first cylinder is configured as four cylinders, which are respectively fixedly installed on the front, rear, left and right sides of the bracket, and the output shafts of the four cylinders all pass through the bracket and are slidably connected to the bracket.

[0010] The clamps are configured as four, with the top ends of the four clamps penetrating through the mounting plate and slidably connected to the mounting plate. One side of the clamps is fixedly mounted on the output shaft of the corresponding first cylinder.

[0011] A transmission assembly is disposed on the top of the support frame and is used to drive the support frame to move.

[0012] As a preferred embodiment of this utility model, the mounting plate is provided with four sliding holes, and the top of the clamp plate passes through the corresponding sliding holes and is slidably connected to the inner wall of the sliding holes.

[0013] As a preferred embodiment of this utility model, an anti-slip pad is fixedly installed on one side of the clamping plate.

[0014] As a preferred embodiment of this utility model, a spring is fixedly installed on one side of the clamping plate, and one end of the spring is fixedly installed on the bottom of the mounting plate.

[0015] As a preferred embodiment of this utility model, the transmission assembly includes a circular plate, a transmission box, a motor, a lead screw, a nut, two electric slide rails, and a top plate. The bottom of the circular plate is in contact with the top of the bracket. The motor is fixedly installed on the right side of the transmission box. The output shaft of the motor passes through the right side of the transmission box and is fixedly installed on the right end of the lead screw. The left end of the lead screw is rotatably connected to the left inner wall of the transmission box. The nut is threaded onto the lead screw. The bottom of the nut is fixedly installed on the top of the circular plate. The top of the transmission box is slidably installed on the bottom of the two electric slide rails. The bottom of the top plate is fixedly installed on the top of the two electric slide rails respectively.

[0016] As a preferred embodiment of this utility model, two second cylinders are fixedly installed on the top of the circular plate, and the output shafts of the two second cylinders pass through the circular plate and are fixedly installed on the top of the bracket.

[0017] As a preferred embodiment of this utility model, a mounting bracket is fixedly installed on the top of the top plate, and multiple mounting holes are provided on the inner wall of the top of the mounting bracket.

[0018] Beneficial effects:

[0019] 1. To solve the problem of unstable clamping and packing of cylindrical bottles, when the cylindrical bottle is located between the four clamping plates, the activation of the four first cylinders can drive the four clamping plates to move closer to each other. Here, the four clamping plates can clamp and fix the cylindrical bottle in front, behind, left, and right positions, thereby ensuring stable gripping of the cylindrical bottle. The four clamping plates can also adapt to gripping materials with gaseous shapes, making them highly versatile.

[0020] 2. In order to enable the movement of the bracket, mounting plate, four first cylinders and four clamping plates, the starting motor drives the lead screw to rotate. Through the threaded connection between the lead screw and the nut, the circular plate, bracket, mounting plate, four first cylinders and four clamping plates can be moved laterally. Then, by starting the two electric slide rails, the bracket, mounting plate, four first cylinders, four clamping plates, circular plate and transmission box can be moved back and forth, thereby realizing the adjustment of the front, back and left and right positions of the four clamping plates, which facilitates the gripping mechanism to pick up and put down objects.

[0021] This invention achieves efficient and stable gripping of cylindrical bottles through a simple structure, improving the gripping stability of cylindrical bottles, and can also adapt to gripping objects of other shapes. It is easy to operate and has strong applicability. Attached Figure Description

The four clamping plates 4 can also adapt to gripping materials with gaseous shapes, making them highly adaptable.

[0035] In order to provide stable support for the movement of the clamping plate 4, four sliding holes 5 are provided on the mounting plate 2. The top of the clamping plate 4 passes through the corresponding sliding hole 5 and is slidably connected to the inner wall of the sliding hole 5.

[0038] To enable movement of the bracket 1, mounting plate 2, four first cylinders 3, and four clamping plates 4, the starting motor 11 drives the lead screw 12 to rotate. Through the threaded connection between the lead screw 12 and the nut 13, the circular plate 8, bracket 1, mounting plate 2, four first cylinders 3, and four clamping plates 4 can move laterally. Then, by activating the two electric slide rails 14, the bracket 1, mounting plate 2, four first cylinders 3, four clamping plates 4, circular plate 8, and transmission box 10 can move back and forth, thus allowing adjustment of the front, back, left, and right positions of the four clamping plates 4. This facilitates the gripping mechanism's object handling operations. The transmission assembly includes... The system includes a circular plate 8, a transmission box 10, a motor 11, a lead screw 12, a nut 13, two electric slide rails 14, and a top plate 15.

Furthermore, the first cylinder 3, the second cylinder 9, the motor 11, and the electric slide rail 14 mentioned above are all existing technologies and will not be elaborated upon in this solution.

[0042] The working principle of this utility model is as follows: In use, firstly, the first cylinder 3, the second cylinder 9, the motor 11, and the electric slide rail 14 are connected to an external power source. Then, when the cylindrical bottle is positioned between the four clamping plates 4, activating the four first cylinders 3 causes the four clamping plates 4 to move closer together. Here, the four clamping plates 4 can clamp and fix the cylindrical bottle in front, back, left, and right positions, thus ensuring stable gripping of the cylindrical bottle. Furthermore, the four clamping plates 4 can also grip materials with gaseous shapes, making them highly adaptable. Additionally, activating the motor 11 drives the lead screw 12 to rotate, thereby... The threaded connection between 12 and nut 13 enables the circular plate 8, bracket 1, mounting plate 2, four first cylinders 3, and four clamping plates 4 to move laterally. Then, by activating the two electric slide rails 14, the bracket 1, mounting plate 2, four first cylinders 3, four clamping plates 4, circular plate 8, and transmission box 10 can move back and forth, thereby enabling the adjustment of the front, back, left, and right positions of the four clamping plates 4.
