Problems solved by technology
The disadvantage is that the uniformity of the adhesive on the wheel tray is poor, resulting in unstable product performance, easy breakage, flying pieces, low grinding efficiency and large floating, etc.
[0003] Existing gluing machines on the market have some defects, such as a wide range of output pressure fluctuations, cannot be lifted when the viscosity is too high, and there is no special heating device. When the temperature drops, the output effect of the adhesive will be affected.

Embodiment Construction
[0028] The present invention will be further described below in conjunction with accompanying drawing by embodiment:
[0029] preferred embodiment
[0030] like figure 1 As shown, a constant temperature and constant pressure quantitative positioning sizing system includes a driving device 1 and a glue pump 2 driven by it. The lower end of the glue pump 2 is connected to the glue bucket 3, and a heating mechanism is arranged on the glue pump 4 Warm the adhesive entering the glue pump 2, the glue pump 2 is connected to the glue sizing device 6 through the glue delivery pipeline 5, and the glue sizing device 6 is used to evenly apply the conveyed adhesive to the grinding wheel disc .
[0031] like figure 2 As shown, the glue pump 2 includes a housing 21 and a piston rod 22 connected to the driving device 1. Two sets of one-way valves 23 are arranged inside the housing 21. The one-way valves 23 are together with the housing 21 and the piston rod 22. The inside of the hous...

The invention relates to a quantitative positioning glue smearing system at constant temperature and constant pressure, in particular to a glue smearing system for automatic production equipment. The invention aims to provide a glue smearing system which is specially used for a sand wheel vane disc and can ensure that liquid matters have the relatively stable pressure fluctuation range in the glue smearing course, the external temperature change has little influence on the liquid matters, and the pressure of an adhesive is stable in the glue smearing course, thereby greatly lowering the use cost of the adhesive. In order to achieve the purpose, the invention adopts the technical scheme that the quantitative positioning glue smearing system at constant temperature and constant pressure comprises a driving device and a glue pump driven by the driving device, wherein the lower end of the glue pump is connected with a glue containing barrel; a heating mechanism is arranged on the glue pump and is used for heating the adhesive flowing into the glue pump; the glue pump is connected with a glue smearing device through a glue delivery pipeline; and the glue smearing device is used for uniformly smearing the delivered adhesive into the sand wheel vane disc. The system provided by the invention can be applied to the delivery of various liquid matters with large viscosity and poor liquidity.
Description
technical field [0001] The invention relates to a sizing system used in automatic production equipment, in particular to a special sizing system for transporting liquid substances with high viscosity and poor fluidity in the production of grinding wheel discs. technical background [0002] The production of the existing abrasive cloth disc (that is, the abrasive disc, which can be called the emery cloth disc, the flat wheel or the emery cloth wheel in popular terms), first prepares the bonding adhesive, puts it in a plastic bag, and puts it in the plastic bag. Cut a small hole at the corner, squeeze out the adhesive by hand and apply it evenly on the wheel tray, then use a special mold to place the emery cloth pieces by hand according to a certain rule, and cover the wheel with resin Pallet, the abrasive cloth sheet and the pallet are bonded together by adhesive, the inner and outer circles are trimmed, and the finished product is finished after the rod is solidified. The d...
