Description

Technical Field

[0001] The utility model relates to the technical field of barrel beer clamps, in particular to a PET barrel clamp. Background Art

[0002] In the field of barreled beer (barrel), a clamp is needed inside the PET barrel filling machine to grasp the barrel neck of the PET barrel to ensure the stable operation of the barrel. With the continuous development of science and technology, the development trend of the clamp used to grasp the PET barrel is increasingly tending towards diversification.

[0003] The existing PET barrel clamps mainly have the following technical defects: the existing PET barrel clamps are mainly single-point hinged through the piston rod in the cylinder and the two connecting rods through a bushing arranged outside the bolt, and then the two connecting rods are respectively connected to the clamps through bushings arranged outside the bolts. In the single-point connection method, the power of the cylinder piston rod is unstable when transmitted to the two connecting rods. At the same time, the movable gap between the connecting rod and the fixed seat is large, which is prone to loosening, thereby causing the problem of low stability of the PET barrel clamp. Utility Model Content

[0006] The external control system controls the external air pump to start, so that the airflow inside the cylinder pushes the piston rod to retract, and then the piston rod drives the cylinder connecting push block fixedly connected to it to move synchronously. While the cylinder connecting push block moves, it drives the connecting rods hinged to it on both sides to rotate. The connecting rod rotates stably under the restriction of the plastic bearing, and then drives the clamping fingers to open. When the external conveyor belt transports the PET barrel to be filled to the corresponding position of the clamping fingers;

[0007] Furthermore, the piston rod and the cylinder connecting push block are connected via threads.

[0008] Furthermore, plastic bearings are sleeved on the outer sides of the connecting pins at the connection between the fixing seat and the clamping fingers and at the connection between the clamping fingers and the connecting rod.

[0009] Furthermore, the fixing seat is composed of two parts, an irregular trapezoidal block and a rectangular block, and the fixing seat is integrally formed. The bottom surface of the fixing seat is in contact with the main mounting plate and is fixedly connected to the main mounting plate by screws.

[0010] Furthermore, the plastic bearing at the fixing seat is tightly sleeved with the inner wall of the clamp finger, and the plastic bearing at the clamp finger is tightly sleeved with the inner wall of the connecting rod, and the connecting rod is tightly clamped between the fixing seats through the plastic bearing.

[0011] The external control system controls the external air pump to start again, so that the airflow inside the cylinder pushes the piston rod outward, and then the cylinder connection push block drives the clamping finger to reset and close through the connecting rod. Since the arc-shaped notch on the clamping finger fits the neck of the PET barrel, the purpose of clamping and fixing the PET barrel is achieved;

[0012] Furthermore, a convex ring for connecting the wine spear is provided on the outer side of the PET wine barrel, and the thickness of the clamping finger is smaller than the distance between the convex ring and the barrel body of the PET wine barrel.

[0013] Compared with the prior art, the utility model provides a PET wine barrel clamp, which has the following beneficial effects:

[0014] The PET barrel clamp, through the cooperation between the cylinder connection push block, the connecting rod, the fixed seat, the connecting pin, the clamping finger and the plastic bearing, makes the cylinder connection push block and the connecting rod hinged at two points through the connecting pin, which changes the existing PET barrel clamp that adopts the single-point hinge method, realizes the stability of power transmission, and at the same time, the plastic bearing at the fixed seat is tightly sleeved with the inner side wall of the clamping finger, the plastic bearing at the clamping finger is tightly sleeved with the inner side wall of the connecting rod, and the connecting rod is tightly clamped between the fixed seats through the plastic bearing, which ensures that the clamping finger will not shake when moving, and solves the problem of low stability of the existing clamps.
