Electric head die clearance adjusting device for blowing machine

Abstract

The invention discloses an electric head die clearance adjusting device for a blowing machine. The device comprises a box body, a cam and an axle cover sleeve, wherein an upper slide block, a cam sliding seat and a lower slide box are arranged in the box body, an upper box cover is arranged at the top of the box body, and a lower box cover is arranged at the bottom of the box body; slide block fixing plates are arranged at positions corresponding to the front side and rear side of the cam sliding seat; a box body left bearing chamber is formed in the left side of the box body; a left bearing cap is arranged at a position on the left side of the box body left bearing chamber; a box body right bearing chamber is formed in the right side of the box body; a right bearing cap is arranged at a position on the right side of the box body right bearing chamber; the cam is matched with the cam sliding seat and supported in the box body left bearing chamber and the box body right bearing chamber; the axle cover sleeve is fixed with a cam left axle; an axle cover is arranged at a position corresponding to the left end face of the axle cover sleeve; a flange is arranged on the axle cover; a motor is matched with a gearbox, and the gearbox and the motor are fixed with the right bearing cap; and the output shaft of the gearbox is connected with the right axle of the cam. The structure is simplified, convenience is brought to manufacture, assembly and routine use and maintenance, and the response speed is increased; and the energy is saved, and the adjusting precision of the head die clearance is ensured.

Description

technical field [0001] The invention belongs to the technical field of blow molding machinery, and in particular relates to an electric adjustment device for the gap between die openings of a head of a blow molding machine. Background technique [0002] The aforementioned blow molding machine is equipment for blowing hollow plastic products, such as various plastic bottles, gallon barrels, water tanks, palletizing barrels and even pallets for stacking goods, etc. [0003] The aforementioned die mouth is also customarily called a die or a die head die, and there is no shortage of technical information about the die structure of a blow molding machine in the published Chinese patent documents, such as CN2837051Y (blow molding machine ring die device), CN102114702B (die structure of plastic blow molding machine), CN102152472B (die structure of plastic blow molding machine with improved structure), CN102145540B (die mechanism of plastic blow molding machine), CN202825606U (a blo...

AI Technical Summary

Problems solved by technology

[0007] However, by reading the full text of the above-mentioned CN101966750B, it can be seen that: due to the need to use forward and reverse drive motors (two motors), clutch reversing device, speed reducer and the transmission connection between the forward and reverse drive motors and the clutch reversing device Two synchronous belts, etc. (see paragraph 0026 of the specification of this patent), so the structure is relatively complicated, and there are corresponding troubles in manufacture, assembly, use and daily management and maintenance
