The feeding device of roller press currently used in the market is to control the opening of the gate by manually adjusting the lead screw, and there is only one ram on both sides of the receiving hopper; when the roller press deviates from the roller, it is impossible to adjust the feeding device by adjusting the ram along the roll width direction, that is, it is unable to automatically control the roll deviation. Therefore, it is necessary to provide a feeding device which can automatically adjust the ram to solve the problem of roller deviation.
summary of the invention
The purpose of the utility model is to provide a belt Displacement sensor Two side double ram automatic adjustment feeding device of roller press. It has the following technical effect: when the roller of the roller press deviates, the reducer and lead screw in the device will pass through Displacement sensor The movement of the gate plate is controlled by the limit device, so as to achieve the development purpose of automatically adjusting the roll deviation of the roller press.

Specific implementation mode
As shown in Fig. 1-2, the feeding device of the roller press with double gate automatic adjustment comprises a feeding hopper (1), a RAM (2) arranged on both sides of each feeding hopper (1), and a RAM (2) arranged on both sides of the feeding hopper (1) ）There are two gate plates (2) on both sides of each feeding hopper (1), and a travel limit switch (7) and a limit block are also arranged on the gate (3)（ 8) The lower part of the feeding hopper (1) is provided with two pairs of rollers (9), and the middle of the two pairs of rollers (9) is connected with a roll gap displacement sensor (10). The number of RAM (2), transmission reducer (3), screw rod (5), screw rod sleeve (6), travel limit switch (7) and limit block (8) are all 4, and the number of rope pulling displacement sensor (4) and roll gap displacement sensor (10) is 2.
The working process of the utility model in the equipment is as follows: when the opposite roller (9) of the roller press deviates, the roll gap displacement sensor (10) between the two roller pairs (9) will display the offset of the roll gap of the pair roll (9) and submit it to the data processing system. The data processing system calculates the opening operation of each of the four shutters (2) according to the offset of the roll gap. At this time, the transmission reducer (3) drives the screw rod (5) and the device The opening of the gate (2) is displayed by the rope displacement sensor (4), and the movement limit of the gate (2) is controlled by the travel limit switch (7), so as to complete the automatic adjustment of the offset roller.
