Description

Avoid pressing from both sides liquid filling machine of material to block rifle

Technical Field

The utility model relates to the field of filling equipment, in particular to a blocking gun of a filling machine, which avoids material clamping.

Background

Sauce material need utilize the liquid filling machine to carry out quantitative filling after processing is accomplished, and block that the rifle is one of the essential element of liquid filling machine, blocks the rifle among the prior art and mainly includes unloading rifle head, sliding sleeve, sealing washer and blocks the pole, blocks pole sliding connection in the unloading rifle head, and the lateral part of unloading rifle head has the sauce material filling tube through the sprue intercommunication, realizes the injection of sauce material through annotating the material cylinder. When sauce is injected, the blocking rod is in a lifting state, and the sauce injection pipe orifice is not blocked; after the sauce material is injected, the blocking rod moves downwards along the blanking gun head to block the injection port.

However, the blocking gun in the prior art has the following problems when in use: 1. the raw materials often exist in the sauce, and when the blocking rod moves down along the blanking gun head, the filamentous raw materials in the sauce are clamped between the inner wall of the gun head and the gap of the blocking rod, the sauce is wrapped by the filamentous materials and moves down along with the blocking rod, and finally the filamentous materials are clamped at the outlet at the bottom end of the blanking gun head. And the sauce clamped at the outlet often falls on the mouth of the packaging bag, so that the sealing is poor and oil leakage occurs in the sealing process of the packaging bag. 2. Because the bottom of blocking the pole is the sauce material of needs direct contact, so block the pole universal adoption at present and be 304 stainless steel, but the stainless steel is the viscous oil, particle in the sauce material and will be attached to on blocking the pole along with oil together, so when blocking pole up-and-down reciprocating motion, will with the repeated frictional contact of sealing washer, particle attached to on blocking the pole will form "rice crust" on the sealing washer surface, once formed, will increase the resistance that blocks pole up-and-down motion, make the sprue can not be timely open completely, the injection pressure of sauce material will multiply, make it be high-pressure high-speed blowout, cause the sauce material to splash four times, not only be unfavorable for the sealed package of wrapping bag, but also can cause very big waste.
