Description

Technical Field

[0001] The utility model relates to the technical field of packaging, in particular to a packaging feeding head. Background Art

[0002] When packaging relatively fine powder materials such as calcium oxide, in order to avoid powder spillage during the feeding process and environmental pollution, a dust-proof cloth sleeve is usually sleeved at the lower end of the discharge pipe of the storage tank. During feeding, the powder will enter the packaging bag through the dust-proof cloth sleeve. However, this method has a poor sealing effect on the packaging bag, so a part of the dust will still spill out, and the ability to collect dust is poor. Content of the Utility Model

[0003] The utility model provides a packaging feeding head to solve the above-mentioned deficiencies of the prior art, solve the problem of more dust spillage during powder feeding, and has strong practicability.

A dust-proof cloth is provided on the lower wall of the closing ring. A plurality of air outlet holes are opened on the closing ring. During packaging feeding, the packaging bag needs to be sleeved on the conical ring. The conical surface structure of the conical ring is used to improve the sealing effect on the bag mouth of the packaging bag. The exhaust holes provided on the bottom ring facilitate the discharge of the air in the packaging bag. The provided dust-proof cloth can avoid further escape of dust and is collected into the cavity formed by the enclosure of the conical ring and the like. First, it can avoid waste of raw materials, and second, it can increase the dust capacity.

A lower plate is installed at the lower end of the vertical rods. A clamping cylinder is installed on the outer end plate. The inner side end of the clamping cylinder is arranged on the clamping ring. Through the provided clamping ring, when it moves driven by the clamping cylinder, it can act on the bag mouth of the packaging bag, so as to stably clamp the packaging bag at the conical ring. In addition, it can also improve the sealing effect of the bag mouth of the packaging bag to prevent dust from escaping during feeding.

[0007] Further, in order to improve the closing effect on the bag mouth of the packaging bag and the fixing effect after clamping the packaging bag, a plurality of anti-slip rings are provided on the outer periphery of the conical ring, and a plurality of anti-slip grooves are formed on the inner wall of the conical ring groove, and the anti-slip rings are located in the anti-slip grooves.

[0008] Further, in order to improve the dust-proof effect and prevent the dust-proof cloth from being blocked due to a large amount of passing dust, a ring plate is provided at the lower end of the inner periphery of the upper ring. A plurality of notches are formed in the inner periphery of the ring plate. A connecting ring is provided at the upper end of the ring plate. An L-shaped clamping member is provided on the lower wall of the connecting ring. The lower end of the L-shaped clamping member is inserted through the notch, and the inner wall of the lower end of the L-shaped clamping member acts on the lower wall of the ring plate. An upward extension ring is provided on the connecting ring. A top ring is provided at the upper end of the upward extension ring. A rubber sleeve is provided in the top ring. The rubber sleeve is sleeved on the discharge pipe. Communication holes are formed in the top ring and the upward extension ring. A dust-proof cloth is provided outside the top ring and the upward extension ring.

[0009] Further, in order to facilitate the connection operation of the connecting ring, a plurality of arc-shaped grooves are formed in the connecting ring, and a limiting rod is inserted through the arc-shaped grooves. The lower end of the limiting rod is provided on the ring plate.

[0010] The advantages of the above technical solutions are as follows:

[0011] The utility model facilitates the feeding and packaging operation of bagged powder materials, and can avoid the escape of dust during feeding and packaging, thereby avoiding environmental pollution. BRIEF DESCRIPTION OF THE DRAWINGS
