Background art:

in shaving board production, the quality of product does not leave the precision control of wood shavings measurement, in the actual production process flow, wood shavings measurement has the branch before the glueing again and before mating formation, in shaving board production, dry wood shavings are after the accurate measurement, control system carries out the accurate glueing to dry wood shavings according to the weight signal that measures feed bin weighing sensor and detect, after the glue mixer glue mixing, glue has been applyed uniformly to the wood shavings, the wood shavings are after the hot pressing of mating formation, panel quality texture is even, each point bonding strength is unanimous, the shaving board of producing just can reach the standard of leaving the factory. Therefore, the wood shaving metering work before gluing is well done, the gluing uniformity can be improved, the glue consumption is reduced, the product quality is stabilized, the waste board is reduced, and the wood utilization rate is improved.

Because the metering bin in front of the core layer glue mixer is unreasonable in design, the prior art has the following defects: 1. the core layer metering bin has small volume, the conveying scraper blade is frequently started and stopped, and gravity impact influences, so that errors and instability are generated when the wood shavings are weighed by a belt scale sensor in the metering bin, the glue amount sprayed into the glue mixer is always fluctuated, and the glue amount of the wood shavings after glue mixing is not uniform; 2. the position deviation is large when the feed opening is over the front; 3. the feed opening is easy to block materials, and signal errors of a metering device of the metering bin are caused, so that the control of the metering belt is disordered, the continuous fluctuation of the glue application amount is caused, and the glue application amount is unstable.

The invention content is as follows:

the to-be-solved technical problem of the utility model is overcome prior art not enough, a shaving board sandwich layer measurement feed bin is provided, its increase measures the volume of feed bin, change feed opening position, rationally make it no longer take place long-pending material putty through the effect of the equal flat roller of returning charge, reduce scraping trigger open and stop the number of times, the metering device signal is accurate, ensure the continuous uniform velocity operation of metering belt, the unloading is even, the glue yield error that the glue mixer squirted reduces, the wood shavings glue mixing is even, ensure that each item physical and chemical parameter of shaving board is stable, the terminal surface is sparse close evenly.

In order to achieve the above purpose, the utility model is realized by adopting the following technical scheme:

a shaving board core layer metering bin comprises a base, wherein a first support is arranged on the base, a conveying device and a bin are arranged on the first support, the conveying device is installed at the bottom of the bin, a blanking channel is arranged above the bin, and a permanent magnet and a metal magnetic attraction retention plate are arranged on the side wall of the blanking channel; the material returning and leveling device is characterized in that more than one material returning and leveling roller is arranged on the stock bin, the material returning and leveling roller is in transmission connection with a second motor, the second motor is fixedly installed on the stock bin, and a discharging opening is further formed in the left side of the stock bin.

Preferably, the conveying device comprises a first motor, a conveying belt and a conveying belt shaft, the first motor is in transmission connection with the conveying belt shaft, and the conveying belt is mounted on the conveying belt shaft.

Preferably, a platform is arranged on one side of the base.

Preferably, the return leveler roller is preferably seven.

Compared with the prior art, the beneficial effects of the utility model are that:

1. the volume of a storage bin and a blanking channel is increased, the position of a blanking opening is changed, the material accumulation and material blockage are avoided reasonably under the action of a material returning leveling roller, the starting and stopping times of a scraper conveyor are reduced, signals of a metering device are accurate, the metering belt is ensured to continuously run at a constant speed, the blanking is uniform, the error of the amount of glue sprayed by a glue mixer is reduced, the wood shavings are uniformly mixed with the glue, various physical and chemical parameters of a shaving board are stable, and the end surfaces are uniformly dense;

2. the material returning leveling rollers are seven, the closer to the feed opening, the lower the material returning leveling rollers are arranged, and the material returning leveling rollers at other positions are at the same height, so that material overstocking at the feed opening can be avoided through the design;

3. the blanking port of the blanking channel firstly falls on a material returning leveling roller and then falls on the conveying belt, so that the impact of falling impact of shavings on the measuring belt scale on the conveying belt is reduced, and the weight deviation of shavings entering the measuring belt scale is improved.
