Description

Technical Field

[0001] This utility model relates to the field of packaging box processing technology, specifically a clamping mechanism for packaging corrugated cardboard boxes. Background Technology

[0002] Corrugated cardboard boxes, as a widely used packaging material, need to be stacked and secured before logistics transportation to prevent deformation or damage caused by shaking during transport. Traditional cardboard box packing clamping mechanisms mostly use mechanical pressure plates or manual adjustment devices to press and secure stacked cardboard boxes. However, traditional pressure plates are usually driven from one side or controlled by an independent power source, making it difficult for the pressure plates on both sides to rise and fall synchronously. This can easily cause uneven force on the cardboard boxes, leading to stack shifting or even tipping over. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a clamping mechanism for packing corrugated cardboard boxes, which can realize the synchronous lifting and lowering of the double-sided pressure plates and improve the transmission efficiency, thereby improving the packing efficiency and stability.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a clamping mechanism for packing corrugated cardboard boxes, including a base plate, with a vertical rail provided at each of the four corners of the top surface of the base plate, and a lifting strip plate provided inside the vertical rail. A strip pressure plate is provided between the bottom ends of the two lifting strip plates on the two vertical rails on the same side of the base plate. The two strip pressure plates move up and down with the lifting strip plates and press and fix the corrugated cardboard boxes stacked on the base plate.

[0005] In a preferred embodiment, the vertical rail is a strip-shaped groove structure, the lifting bar is vertically arranged in the vertical rail, and extensions are provided on both sides of the middle of the opening side of the vertical rail. Full gears and incomplete gears are provided on the extensions, and the full gears and incomplete gears mesh with each other.

[0006] The lifting bar is provided with a rack on the side facing the vertical rail opening, and the rack also meshes with the full gear and the incomplete gear.

[0007] In a preferred embodiment, the incomplete gears in the four vertical rails are divided into two groups, and the two incomplete gears in the same group are connected by a transmission rod, and the two transmission rods on the two groups of incomplete gears are engaged in transmission.

[0008] In a preferred embodiment, each of the two transmission rods is provided with a pulley, and the two pulleys are connected by a first transmission belt.

[0009] In a preferred embodiment, one end of the transmission rod on one of the vertical rails extends to the outside of one side of the vertical rail, and a drive shaft extends through the side wall of the same side as the base plate. The drive shaft and the extended part of the transmission rod above are connected by a second transmission belt.

[0010] In a preferred embodiment, the base plate is equipped with a drive device, which is used to drive the drive shaft.

[0011] In a preferred embodiment, a groove is provided on the top surface of the base plate, and the groove direction is perpendicular to the transmission rod.

[0012] In a preferred embodiment, the incomplete gear includes two symmetrical tooth segments.

[0013] The clamping mechanism for packing corrugated cardboard boxes provided by this utility model has the following advantages by adopting the above structure:

[0014] (1) The lifting strips in the four vertical rails are driven by the meshing of full gears, incomplete gears and racks. Combined with the linkage design of transmission rod and pulley, it can ensure that the strip pressure plates on both sides of the bottom plate are lifted and lowered synchronously, completely avoiding the problem of pressure force deviation caused by traditional single-sided drive, so that the stacked paper boxes are subjected to uniform force and prevent tipping or deformation.

[0015] (2) The meshing transmission of full gear and incomplete gear combined with the rigid guidance of rack avoids the clearance error of traditional screw transmission and improves transmission accuracy. The intermittent meshing characteristics of incomplete gear can reduce gear wear. Combined with the stress relief of the transmission rod by slotting, it extends the service life of key components.

[0020] like Figure 1-2 In a clamping mechanism for packing corrugated cardboard boxes, there is a base plate 1. A vertical rail 2 is provided on each of the four corners of the top surface of the base plate 1. A lifting strip 3 is provided inside the vertical rail 2. A strip pressure plate 12 is provided between the bottom ends of the two lifting strips 3 on the two vertical rails 2 on the same side of the base plate 1. The two strip pressure plates 12 move up and down with the lifting strips 3 and press and fix the corrugated cardboard boxes stacked on the base plate 1.

[0021] In a preferred embodiment, the vertical rail 2 is a strip-shaped groove structure, the lifting bar 3 is vertically arranged in the vertical rail 2, and extensions are provided on both sides of the middle of the opening side of the vertical rail 2. The extensions are provided with a full gear 5 and an incomplete gear 6, which mesh with each other.

[0022] The lifting bar 3 is provided with a rack 4 on the side facing the opening of the vertical rail 2. The rack 4 also meshes with the full gear 5 and the incomplete gear 6.

[0023] In a preferred embodiment, the incomplete gears 6 in the four vertical rails 2 are divided into two groups, and the two incomplete gears 6 in the same group are connected by a transmission rod 7, and the two transmission rods 7 on the two groups of incomplete gears 6 are engaged in transmission.

[0024] In a preferred embodiment, each of the two transmission rods 7 is provided with a pulley 8, and the two pulleys 8 are connected by a first transmission belt 9.

[0025] In a preferred embodiment, one end of the transmission rod 7 on one of the vertical rails 2 extends to the outside of one side of the vertical rail 2, and a drive shaft 10 extends through the side wall of the base plate 1 on the same side. The drive shaft 10 and the extended part of the transmission rod 7 above are connected by a second transmission belt 11.

[0026] In a preferred embodiment, the base plate 1 is equipped with a drive device, which is used to drive the drive shaft 10.

[0027] In a preferred embodiment, a slot 13 is provided on the top surface of the base plate 1, and the direction of the slot 13 is perpendicular to the transmission rod 7.

[0029] The clamping mechanism for packing corrugated cardboard boxes disclosed in this invention, during the clamping process before packing the corrugated cardboard boxes:

[0030] Beforehand, packing rope is placed in the slot 13. Then, the corrugated cardboard box to be packed is placed on the base plate 1. The drive device in the base plate 1 drives the two drive shafts 10 to rotate. During the process, the incomplete gear 6 first engages with the rack 4 to press down the lifting strip 3, thereby pressing the two strip pressure plates 12 to the edges of the corrugated cardboard box to be packed. After pressing, the drive device stops, and then the corrugated cardboard box is tied with the packing rope.

[0031] After the operation is completed, the drive equipment runs again, causing the incomplete gear 6 to drive the full gear 5 to rotate in the opposite direction, thereby realizing the lifting action of the lifting plate 3 and releasing the pressure on the corrugated cardboard box.
