Description of the embodiments
The following describes the embodiments of the present utility model in detail with reference to the drawings.
In this embodiment, a lifting and limiting mechanism for a brush roller support seat is specifically disclosed, as shown in fig. 1-9, the specific structure of the lifting and limiting mechanism includes a limiting component 13 connected to a side wall of a lower support seat 203a, and a lower roller seat 201a capable of relatively lifting and lowering the lower support seat 203a is arranged above the lower support seat 203 a; the limiting assembly 13 comprises a support 1301, wherein a vertically arranged limiting rod 1302 is fixedly connected to the support 1301, and the limiting rod 1302 extends upwards and penetrates into the lower roller seat 201a; the stop lever 1302 is further provided with a first stop portion 1303 disposed in the lower roller seat 201a and a second stop portion 1304 disposed outside the lower roller seat 201a, and a distance between the first stop portion 1303 and the second stop portion 1304 in the vertical direction is a maximum lifting travel of the lower roller seat 201a; in the upward adjustment state of the lower roller seat 201a, the lower roller seat 201a can be prevented from continuously moving upwards when the bottom plate of the lower roller seat 201a is in abutting limit with the first limiting part 1303, and the lower roller seat 201a can be prevented from continuously moving downwards when the bottom plate of the lower roller seat 201a is in abutting limit with the second limiting part 1304.
In production, the brush rolls supported on the lower roll seat 201a brush the fed steel plate, in order to improve the brushing efficiency, the lower roll seat 201a and the lower support seat 203a may be rotated 180 degrees and inverted above the steel plate to form the upper roll seat 201b and the upper support seat 203b, the upper roll seat 201b and the upper support seat 203b are respectively erected on the top end and the bottom end of the frame 7, and simultaneously brush the upper surface and the lower surface of the steel plate, and the abrasive on the surface of the brush rolls is gradually worn, so that the lower roll seat 201a and the upper roll seat 201b need to be adjusted in a lifting manner so that the brush rolls are attached to the surface of the steel plate, although the amplitude and the range of the lifting adjustment are not large, if the adjustment is excessive, the lower roll seat 201a is possibly disconnected from the lower support seat 203a, or the upper roll seat 201b is possibly disconnected from the upper support seat 203 b. When the surface abrasive of the brush roll is completely worn, a new brush roll needs to be replaced, and at this time, the lower roll stand 201a and the upper roll stand 201b need to be lifted and adjusted again, and at this time, if the adjustment is excessive, the lower roll stand 201a and the lower support stand 203a are easy to collide and squeeze, or the upper roll stand 201b and the upper support stand 203b are easy to collide and squeeze.
The first limiting part 1303 and the second limiting part 1304 in the limiting assembly 13 can limit the lifting range of the lower roller seat 201a or the upper roller seat 201b, respectively, and the distance between the two limiting parts is the maximum stroke of lifting adjustment. Taking the lower roller seat 201a as an example, during upward adjustment, the brush roller can be always attached to the surface of the steel plate, and when the first limiting part 1303 contacts the bottom plate of the lower roller seat 201a, the lower roller seat 201a is limited to move upward continuously; during the downward adjustment, when the second limiting portion 1304 contacts the bottom plate of the lower roller seat 201a, the lower roller seat 201a is limited to move downward to collide with the lower supporting seat 203a.
In addition, in order to improve the accuracy and stability of the lifting limit, two proximity switches 1305 are arranged up and down on the inner side wall of the lower roller seat 201a, and the proximity switches 1305 are located on the same straight line in the vertical direction; the first limiting part 1303 extends toward the proximity switch 1305, so that the first limiting part 1303 can trigger the proximity switch 1305 when the lower roller seat moves up and down, and the proximity switch 1305 is electrically connected with a controller and a driving device for driving the lower roller seat 201a to move up and down.
The proximity switch 1305 can form double limiting with the first limiting part 1303 and the second limiting part 1304, so that a safety is added, and the control is more accurate through an electric signal; the distance between the two proximity switches 1305 is smaller than the distance between the first spacing part 1303 and the second spacing part 1304; in the ascent adjustment limit state, the first limit part 1303 is flush with the proximity switch 1305 located above, and the second limit part 1303 is located near the bottom plate of the lower roller seat 201a; in the descent control limit state, the first limit portion 1303 is flush with the proximity switch 1305 located below, and the second limit portion 1303 is located at a position away from the bottom plate of the lower roller seat 201 a.
When the lower roller seat 201a is limited, as the two proximity switches 1305 are positioned in the maximum travel range of the first limiting part 1303 and the second limiting part 1304, when the first limiting part 1303 approaches to the two proximity switches 1305, the proximity switches 1305 capture signals and then the controller sends out signals to enable the driving device to stop lifting adjustment of the lower roller seat 201a; if the proximity switch 1305 is damaged and does not act, the first limiting portion 1303 and the second limiting portion 1304 continue to act as a limit, preventing the lower roller seat 201a from being disconnected from the lower supporting seat 203a.
The first limiting part 1303 is connected to the top end of the limiting rod 1302, and the second limiting part 1304 is sleeved on the limiting rod 1302. If the first limiting portion 1303 is connected to the middle portion of the limiting lever 1302, the portion of the limiting lever 1302 above the first limiting portion 1303 does not have any effect, and occupies space, so that the increase in the height of the lower roller seat 201a increases the production cost and the weight of the lower roller seat 201 a.
Because the production environment is complex, not only is more sewage, dust and debris, but also the movement during roll replacement is easy to collide, although the proximity switch 1305 is connected to the side wall inside the lower roll seat 201a, if the proximity switch 1305 is collided, the dislocation of the proximity switch 1305 can also be caused, so that the lifting limit is influenced, and the side wall of the lower roll seat 201a is also arranged on the protective cover 1306 at the corresponding position of the proximity switch 1305; the protective cover 1306 can perform a good protection function.
The specific way to relatively lift the lower roller seat 201a is: a lifting base 1001 is arranged in the lower roller seat 201a, a worm gear mechanism is arranged at the top of the lifting base 1001, a worm is connected with a transmission shaft 1003 extending out of the lower roller seat 201a, a lifting driving motor 1004 is further connected to the side wall of the lower roller seat 201a, and the output end of the lifting driving motor 1004 is fixedly connected with the transmission shaft 1003; a screw rod 1005 is connected to the axis position of the worm wheel, a lifting sliding sleeve 1006 is fixedly connected to the lower supporting seat 203a, a nut 1007 is fixedly connected to the top end of the lifting sliding sleeve 1006, and the nut 1007 is connected with the screw rod 1005; in the working state, the lifting driving motor 1004 drives the worm and gear mechanism to act through the transmission shaft 1003, so that the screw rod 1005 rotates along with the worm gear, and the screw rod 1005 drives the nut 1007 and the lifting sliding sleeve 1006 fixedly connected with the nut 1007 to move relatively, so that the lower roller seat 201a can lift relatively.
The foregoing description of the utility model is merely exemplary of the utility model. Those skilled in the art may make various modifications or additions to the described embodiments or substitutions, without departing from the scope of the utility model as defined in the accompanying claims.
