Description

Technical Field

[0001] The invention relates to the technical field of rock wool board processing, and in particular to a rock wool board processing cotton wool collecting device and a cotton collecting method thereof. Background Art

[0002] Rock wool is an inorganic fiber made from natural rocks such as basalt, gabbro, dolomite, iron ore, bauxite, etc. as the main raw materials, which are melted at high temperature and fiberized. During the production of rock wool, basalt and other raw materials are melted and centrifuged into fibers, which are then felted by a cotton collector and folded and shaped. The cotton collector is one of the important equipment in the entire rock wool production line.

[0003] When the existing cotton collecting device is working, some rock wool will enter the negative pressure pipe and the negative pressure chamber through the pores of the cotton suction net, and finally enter the negative pressure equipment, affecting the negative pressure equipment; at the same time, when collecting cotton, the rock wool contains some fine rock impurities. When the rock wool is adsorbed on the cotton suction net, the rock impurities hit the cotton suction net and block the pores of the cotton suction net, thereby causing damage to the cotton suction net. The cotton suction net needs to be replaced and repaired. The existing cotton suction net is connected to the cotton collecting device by bolts and locks. During maintenance, the cotton suction net needs to be manually disassembled and carried. Due to the large size and weight of the cotton suction net, the maintenance efficiency is low and the maintenance operation is complicated during the actual loading and unloading process.

When the rock wool is adsorbed on the cotton suction net, the rock impurities impact the cotton suction net and block the air holes of the cotton suction net, thereby causing damage to the cotton suction net, and the cotton suction net needs to be replaced and repaired. The existing cotton suction net is connected to the cotton collecting device by bolts and locks. When repairing, the cotton suction net needs to be manually disassembled and carried.

[0018] Step 1: The negative pressure equipment works, and negative pressure is generated in the annular filter, negative pressure pipe and negative pressure chamber. At this time, the rock wool in the cotton collecting chamber is adsorbed on the cotton suction net. The first motor drives the active gear to cooperate with the meshing external gear to realize the rotation of the drum seat and the cotton suction net. The rock wool is blown away by the cotton lifting air gun, and the cotton suction net is cleaned and removed by the high-pressure cleaning gun. The inner and outer sides of the cotton suction net are air-dried respectively by the inner and outer air-drying seats.

[0019] Step 2: The second motor drives the ring seat to rotate, thereby realizing the rotation of the annular filter. As the annular filter rotates, the scraper scrapes off the rock wool attached to the annular filter;

[0020] The third step is to drive the threaded rod to rotate through the third motor, thereby driving the threadedly connected slide to translate, and when the slide and the support seat are translated to the bottom of the cotton suction net, the first pneumatic cylinder drives the support seat to move up to contact with the cotton suction net, and the second pneumatic cylinder drives the push plate to move and contact with the contact plate, drives the first rack to move in the rack groove to drive the rotating gear to rotate, and the rotating gear rotation drives the second rack to move, and the first arc block and the first plug column are collected into the storage groove through the connecting rod.

[0021] Step 4: When the support seat is raised or lowered to match the height of the second arc block, the second arc block and the second plug column are driven to move by the third pneumatic cylinder. When the second arc block and the second plug column are separated from the arc groove and the plug hole of the connecting seat, it is convenient to place the cotton-absorbing net on the support seat. When the second arc block is inserted into the arc groove of the connecting seat and the second plug column is inserted into the plug hole of the connecting seat, it is convenient to store the cotton-absorbing net on the support seat.

[0022] The beneficial effects of the present invention are as follows: the rock wool entering the negative pressure pipe and the negative pressure chamber is isolated by the annular filter, the annular seat and the annular filter are rotated by the second motor, and the rock wool attached to the surface of the annular filter is scraped off in cooperation with the fixed scraper, thereby preventing the rock wool from entering the negative pressure equipment and affecting the normal operation of the negative pressure equipment;

When the slide (40) and the support seat (42) are translated to the bottom of the cotton suction net (6), the first pneumatic cylinder (41) drives the support seat (42) to move upward to contact the cotton suction net (6), and the push plate (44) is driven by the second pneumatic cylinder (43) to move and contact the contact plate (32), driving the first rack (31) to move in the rack groove (28) to drive the rotating gear (30) to rotate, and the rotation of the rotating gear (30) drives the second rack (33) to move, and the first arc block (26) and the first plug column (27) are stored in the storage groove (34) through the connecting rod (35). At this time, the first arc block (26) and The arc groove (24) of the connecting seat (23) is separated, the first plug post (27) is separated from the socket (25) of the connecting seat (23), the cotton suction net (6) moves down with the support seat (42), and then moves out from under the negative pressure tube (1), at this time, the cotton suction net (6) on the support seat (42) is removed, and a new cotton suction net (6) is placed on the support seat (42), the support seat (42) moves to move the support seat (42) to the installation position, the second pneumatic cylinder (43) contracts and separates from the contact plate (32), the spring (36) returns to its original state, the first arc block (26) is inserted into the arc groove (24) of the connecting seat (23) to separate, the first plug post (27) is inserted into the socket (25) of the connecting seat (23), and the automatic loading and unloading of the cotton suction net (6) is completed; Step 4: When the support seat (42) is lifted or lowered to match the height of the second arc block (47), the second arc block (47) and the second plug post (48) are driven to move by the third pneumatic cylinder (46). When the second arc block (47) and the second plug post (48) are separated from the arc groove (24) and the insertion hole (25) of the connecting seat (23), it is convenient to place the cotton suction net (6) on the support seat (42). When the second arc block (47) is inserted into the arc groove (24) of the connecting seat (23) and the second plug post (48) is inserted into the insertion hole (25) of the connecting seat (23), it is convenient to store the cotton suction net (6) on the support seat (42).
