Embodiment Construction

[0015] The silicone grease filling head of the present invention will be described in further detail below in conjunction with the accompanying drawings and specific examples:

[0016] Such as figure 1 As shown, the silicone grease filling head of the present invention includes a filling needle 1 and a main cylinder 4 for driving the filling needle 1 to enter and exit the hole 8 of the part to be filled. The end of the piston rod of the main cylinder 4 is provided with a connecting block 7, and the afterbody of the filling needle 1 is hinged in the through hole vertically provided on the connecting block 7. The connecting fast 7 is also horizontally provided with a filling needle swing mechanism, which is used to drive the filling needle 1 to swing around its hinge shaft 3 . The filling needle swing mechanism in this embodiment includes a small air cylinder 2 and a push rod 6 arranged horizontally on both sides of the through hole of the connecting block 7 .

Abstract

The invention relates to a point gum machine, in particular to a silicone grease filling head which is suitable for silicone grease and glue solution with large viscosity and difficult glue break andcan be used for overcoming the problem of incapability of controlling the filling amount caused by the silicone grease remaining outside a hole when the glue break of the existing silicone grease filling head occurs. The silicone grease filling head comprises a filing needle and a master cylinder for driving the filing needle to enter and exit a filled part hole. The tail part of the filing needleis hinged on a piston rod of the master cylinder. A filing needle swinging mechanism is arranged beside the filing needle and used for driving the filing needle to swing around a hinge shaft. An inclined surface capable of clinging to the inner wall of the filled part hole is arranged at the head part of the filing needle. Through the setting of the filing needle swinging mechanism and the filingneedle with an inclined surface filling head in the silicone grease filling head, a glue break working procedure can be completely finished on the inner wall of the filled part hole, ensuring that the set silicone grease all enters the filled part hole without remaining outside the hole, ensuring uniform and consistent filling, and further markedly improving the qualification ratio and the quality of temperature regulator finished products.

Description

technical field [0001] The invention relates to a glue dispensing machine, in particular to a silicone grease filling head suitable for silicone grease and glue liquid with high viscosity and difficult to break. Background technique [0002] Filling silicone grease is an important process in the production of thermostats. Each hose of the thermostat needs to be filled with 20-35 mg of silicone grease. If the filling amount of silicon grease is too small, the lubrication of the push rod will be insufficient, which will shorten the life of the thermostat; if the filling amount of silicon grease is too much, resulting in leakage of silicon grease, the lift will drop too much, cause the thermostat to fail. [0003] At present, most of the dispensing machines in the world and abroad adopt the glue-cutting method of vacuum back suction. This method is suitable for most viscosities of glue and grease, but it still cannot break the glue for silicone grease that cannot flow. An exi...
