Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of filling machines, in particular to an extrusion type clamping device for a filling machine. Background Art
[0002] Filling machines are mainly a small category of packaging machines. From the perspective of material packaging, they can be divided into liquid filling machines, paste filling machines, powder filling machines, and granule filling machines; in terms of the degree of production automation, they can be divided into semi-automatic filling machines and fully automatic filling production lines.
[0003] At present, in the filling production line of wine and beverages, the filling part of some PET bottle filling machines adopts non-contact filling valves, that is, the filling valve mouth has no contact with the bottle mouth to be filled. For this filling method, the bottle mouth clamping method of the filling part usually adopts the clamping method of spring-type opening and closing clamps, such as Figure 4-5 As shown in the figure, this method mainly includes a spring, a pair of bottle mouth clamps, a fixing plate, a mounting plate, a pin and other structures; this method clamps the bottle mouth by the spring expansion and contraction, and the bottle mouth clamp is used to hold the bottle mouth to prevent it from falling; therefore, when clamping the bottle mouth in this method, the spring frequently opens and closes to a large extent, and the spring is prone to breakage in actual production. At the same time, the existing filling method also adopts the squeeze-in bottle mouth clamping method, such as Figure 6 As shown, this bottle mouth clamping method is to process a plate with a notch according to the size of the bottle mouth, which can also be called a bottle mouth clamping plate, and add a protrusion at the notch insertion end; when the bottle mouth is inserted, the bottle mouth is slightly deformed, and after being inserted into the notch, the protrusion limits the position of the bottle mouth, so that it will not fall off during the operation of the filling machine. This method has high requirements for the protrusion size and strict restrictions on the bottle mouth size; if the bottle mouth size between different bottle types is slightly different, it is easy to cause the bottle mouth to be thrown out or the bottle mouth to be too tight when the equipment is running. Therefore, the utility model designs an extrusion clamping device for a filling machine. Utility Model Content
