Detailed Description

The invention is further described with reference to specific embodiments and the accompanying drawings.

Example 1

As shown in fig. 1, a parallel feeding device of a roller press is used for feeding materials between squeeze rollers for processing when the roller press works, and the device mainly comprises a frame 1, a telescopic mechanism 2, a material blocking frame 3 and a material sealing mechanism 4, and the specific structure and the working principle of the device are described in detail below.

Frame 1 is feed arrangement's main body frame, and feed inlet 11 has been seted up on its top, and the lower extreme then is equipped with discharge gate 12, and discharge gate 12 below is the position between two squeeze rolls promptly, and the material gets into from feed inlet 11, falls into to process between the squeeze roll from discharge gate 12.

As shown in fig. 2, the telescopic mechanism 2 and the material blocking frame 3 are installed on the frame 1, and are used for controlling the opening of the material falling into the squeeze rollers, so that the material can accurately enter parts between the squeeze rollers, the two parts are provided with a pair of parts which are respectively symmetrically arranged on two sides of the feeding hole 11, the material blocking frame 3 is provided with the material blocking plate 5 through the bolt fixed mounting, and the material blocking plate 5 can be conveniently and quickly replaced when the material blocking plate 5 is seriously worn. Telescopic machanism 2 fixed mounting is in frame 1, and its pars contractilis is connected with stock stop 3 is articulated, and telescopic machanism 2 can adopt cylinder, pneumatic cylinder or electric putter etc. and this embodiment adopts hydraulic cylinder as telescopic machanism 2.

The material blocking frame 3 comprises an inclined plane section 31 and a vertical section 32, the inclined plane section 31 is located below the feed port 11, and a flaring structure is formed between the two inclined plane sections 31 and can collect materials entering from the feed port 11. The vertical section 32 is located above the position between the two extrusion rollers, and the connection part of the vertical section and the upper inclined section 31 is of a bent transition structure. Because the striker plate 5 of the vertical section 32 close to the squeeze roll is of a vertically arranged structure, the friction between the striker plate and the material is greatly reduced compared with the friction between the conventional inclined striker plate and the material, and the service life of the striker plate 5 is prolonged.

Keep off work or material rest 3 and articulate through first connecting rod 33 and second connecting rod 34 and frame 1 respectively and be connected, it is concrete, be connected through first connecting rod 33 is articulated between inclined plane section 31 and the frame 1, be connected through second connecting rod 34 is articulated between vertical section 32 and the frame 1, and first connecting rod 33 and second connecting rod 34 keep parallel state, thereby make first connecting rod 33, second connecting rod 34, frame 1 and keep off and form a parallelogram structure between the work or material rest 3, when telescopic machanism 2 control keeps off work or material rest 3 flexible, vertical section 32 can keep vertical state always. It should be noted that the length between the two hinge points of the first connecting rod 33 to the frame 1 and the striker rod 3 should be equal to the length between the two hinge points of the second connecting rod 34 to the frame 1 and the striker rod 3, so as to form a parallelogram structure.

In addition, in this embodiment, striker plate 5 adopts the antifriction plate, can improve the life of striker plate, and is equipped with elastic buffer layer 6 between striker plate 5 and the stock stop 3, to the impact force of stock stop 3 when can buffering the material whereabouts, improves the life of stock stop 3, and in this embodiment, elastic buffer layer 6 is the rubber layer. Meanwhile, an observation window is further formed in the machine frame 1, the working condition inside the feeding device can be observed, and equipment can be closed in time and maintained and repaired conveniently when faults occur.

However, although the friction between the striker plate 5 on the vertical section 32 close to the squeeze roll and the material can be reduced through the above manner, because the junction of the inclined plane section 31 and the vertical section 32 is of a bent structure, when the material enters the vertical section 32 from the inclined plane section 31, a sudden change of speed and direction exists, the abrasion to the junction is very large, the junction can be worn through even after the working time is long, so that the material enters other positions of the equipment from the worn notch, the work of parts at other positions causes abrasion and influence, the shutdown maintenance is needed, and the work of the roll squeezer is greatly influenced.

In response to this problem, the present embodiment takes the following measures. As shown in fig. 2 and 3, a storage bin 35 is arranged inside the stock stop 3 at the joint of the inclined plane section 31 and the vertical section 32, and the bottom of the storage bin 35 is lower than the joint of the inclined plane section 31 and the vertical section 32. After the junction at inclined plane section 31 and vertical section 32 is worn through, the material can get into storage silo 35 from the position of wearing through and form in storage silo 35 and pile up, can not scatter to all the other positions of equipment, after storage silo 35 is piled up, accumulational material can pile up to the breach department of being worn through, when follow-up material is once more through this department, can form the phenomenon of material abrasive material with the accumulational material of breach department, prevent that the material from continuing to lead to the fact wearing and tearing to stock stop 3 and striker plate 5 of this department, thereby improve equipment's life greatly.

Besides, one side of the storage bin 35 is in contact with the joint of the inclined plane section 31 and the vertical section 32, the other side of the storage bin is provided with a discharge opening 36, and the discharge opening 36 is opened and closed through a discharge plate 37. One end of the discharging plate 37 is hinged to one side of the discharging opening 36, and the other end of the discharging plate is detachably and fixedly connected to the other side of the discharging opening 36, such as a clamping connection, a bolt connection and the like, wherein the clamping connection is adopted in the embodiment. After the equipment stops working, the staff can discharge the materials piled up in the storage bin 35 by opening the discharging plate 37, and then close the storage bin 35.

In addition, due to the adjustment of the telescopic mechanism 2 on the material blocking frame 3, a certain space is inevitably formed between the inclined plane section 31 and the feeding hole 11 for the movement of the inclined plane section 31. Therefore, when the material enters the inclined plane section 31 from the feed inlet 11, the material easily enters other positions of the equipment from the gap between the upper part of the inclined plane section 31 and the feed inlet 11, and causes abrasion and influence on other parts of the equipment, if the conventional closed structure is fixedly installed above the inclined plane section 31, the closed structure needs to be detached before the material blocking frame 3 is adjusted every time, and the closed structure needs to be reinstalled after the material blocking frame 3 is adjusted, which is extremely troublesome. In view of this, the sealing mechanism 4 of the present embodiment perfectly solves this problem.

As shown in fig. 4, the sealing mechanism 4 has two parts, which are symmetrically installed on the frame 1 at both sides of the feeding hole 11, and include a support plate 41, a sealing plate 42 and a guide rod 43. The support plate 41 is mounted on the upper portion of the frame 1, is located on the side of the feed port 11, and is arranged along the height direction. The upper portion of fulcrum plate 41 is equipped with connecting block 45 that has the through-hole, and guide bar 43 passes through the through-hole of connecting block 45 and is connected with connecting block 45 fixed connection and extend along vertical direction, and in this embodiment, the upper portion outside of guide bar 43 is equipped with the screw thread, and it passes through the through-hole of connecting block 45 and passes through guide bar 43 upper end screw nut fixed, can adjust the position of guide bar 43 through this kind of mode for guide bar 43 lower part position can be adjusted. The material sealing plate 42 is provided with a collar 44, and the collar 44 is sleeved on the guide rod 43, so that the material sealing plate 42 can move up and down along the guide rod 43.

When telescopic machanism 2 adjusted the position of keeping off work or material rest 3, the flitch 42 can paste on striker plate 5 under the action of gravity of self, prevents that the material that gets into from feed inlet 11 from getting into all the other positions of equipment in the gap between feed inlet 11 and striker plate 5, causes the influence to all the other parts of equipment. When the striker plate 5 rises, the material sealing plate 42 can be pushed upwards, and when the striker plate 5 falls, the material sealing plate 42 falls down, so that the automatic sealing of the gap between the striker plate 5 and the feed port 11 is realized.

In addition, the guide rod 43 between the lantern ring 44 and the connecting block 45 is externally sleeved with a spring, the spring is in a compression state, when the position of the striker plate 5 is adjusted by the telescopic mechanism 2, the material sealing plate 42 is tightly pressed on the striker plate 5, the looseness of the material sealing plate 42 in the working process of equipment is prevented, and the sealing effect on materials is enhanced. Meanwhile, a sliding rail is arranged on the side surface, close to the material sealing plate 42, of the outer side of the support plate 41, and a sliding block matched with the sliding rail is arranged on the material sealing plate 42, so that the direction precision of the material sealing plate 42 in the moving process can be improved, the material sealing plate 42 is prevented from shaking, and the material sealing effect is further enhanced.
