Background

The open mill is an open rubber mixing machine for short. The rubber factory is used for preparing plasticated rubber, mixed rubber or a rubber mixing machine with an exposed roller for hot mixing and discharging. The main working components are two hollow rollers or drilling rollers which rotate in different directions inwards, one side of the device, called a front roller, of an operator can horizontally move back and forth through manual or electric operation so as to adjust the roller distance and adapt to the operation requirement; the rear roller is fixed and cannot move back and forth. The two rollers are generally the same in size and rotate relatively at different speeds, and raw rubber or rubber compound is rolled into the gap between the two rollers along with the rotation of the rollers and is subjected to strong shearing action to achieve the purpose of plastication or mixing.

At present, when current mill was using, thoughtlessly had metal particle in the plastic powder material, caused the condition of mill damage very easily to, because the rubber roll upper temperature of smelting of mill is higher, when the manual plastic powder material of pouring on smelting the rubber roll, scald the condition of hand appears easily in the workman.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a safety device of mill to thoughtlessly there is the metal granule in solving the plastic powder, causes the condition of mill damage very easily, and, because the rubber roll upper temperature of smelting of mill is higher, when the manual plastic powder that falls on to smelting the rubber roll of workman, the problem of the condition of scalding the hand appears easily.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a safety device of mill, includes the mill body, install the support on the mill body, install circular lauter tub on the support, install the filter screen in the circular lauter tub, the pot head of circular lauter tub is equipped with the bung, install dwang and motor on the bung, the dwang is installed in the pivot of motor, the brush is installed to the lower extreme of dwang, and the surface of brush is hugged closely on the filter screen, the motor drives the dwang and rotates, and the dwang drives the powder that the brush brushed the filter screen surface, can not only lead to the filter screen and strain the metal particle in the plastic powder, can add the filtration efficiency on the filter screen fast moreover.

Preferably, the barrel cover is provided with a feed inlet, the feed inlet is provided with a feed hopper, and the feed hopper is convenient for feeding into the circular filter barrel.

Preferably, the barrel cover is provided with a groove, a pin rod is sleeved in the groove, a pin groove is formed in the circular filter barrel, one end of the pin rod is inserted into the pin groove, the barrel cover can be fixed through the pin rod, and the situation that the barrel cover is separated from the circular filter barrel due to vibration generated during the operation of a motor is avoided.

Preferably, a pull ring is installed at one end of the pin rod, and a worker can conveniently and manually control the pulling of the pin rod through the pull ring.

Preferably, install the annular plate on the pin rod, install the spring between recess and the annular plate, the one end of spring is passed through the turn-buckle and is installed on the inner wall of recess, and the other end passes through the turn-buckle and installs on the annular plate, supports the annular plate through the spring, can avoid appearing the automatic condition that breaks away from the cotter way of pin rod.

Compared with the prior art, the beneficial effects of the utility model are that: the brush is driven by the motor to brush the powder on the surface of the filter screen, so that not only can metal particles in the plastic powder be filtered by the filter screen, but also the filtering efficiency of the powder on the filter screen can be increased; the plastic powder falls onto the rubber refining roller of the rubber refining machine body through the lower end of the circular filter barrel, so that the condition that workers scald hands during material pouring can be avoided; through drawing the pin rod into the groove, the barrel cover is convenient to detach, so that the surface of the filter screen can be cleaned, and the condition that metal particles are accumulated on the filter screen to influence the filtering effect is avoided.
