Technical field
The utility model relates to snowflake sand machine equipment technical field, in particular to a kind of snowflake sand machine live-roller fast lifting
Structure.
Background technique
The processing of plate surface, such as surface frosted, polishing, deburring, the plate small for area can by hand or hand
The small-sized polishing machine of formula to be held to complete, locality is big, it is not suitable for the polishing of the biggish object such as plate, and then for large area plate
Larger sanding machine is needed, needs pinch roller to carry out transport sheet material to complete each step.In practice, it has been found that once in process
Middle appearance is unexpected, such as has a power failure or sundries enters and needs emergency stop, at this time since pinch roller is the quilt in the case where clamping plate
Compel to stop, directly will lead to the failure of plate surface processing work, can only re-work or scrap, seriously affects production effect
Rate.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of snowflake sand machine live-roller fast lifting structures, to solve
It is unexpected in process appearance in the prior art, make pinch roller be forced to stop and cause the problem to processing plate breakage.
In order to solve the above-mentioned technical problem, the technical solution of the utility model are as follows:

Guide groove is stated to be connected;Spring is arranged in the accommodating chamber, and stretches in a free state into the guide groove;It is driven
Roller, the driven roller center are equipped with connecting shaft, and the connecting shaft both ends are equipped with folk prescription spindle nose, and the driven voller passes through the connection
The folk prescription spindle nose at axis both ends is mounted in the guide groove, and folk prescription spindle nose bottom end is mutually supported with the spring top;Gas
Cylinder is arranged at the top of mounting base, and the cylinder output extends in the guide groove, and is directed at the upper end of the folk prescription spindle nose
Face.
Preferably, the lower section that the driven voller is corresponded in the rack is equipped with drive roll, the stretching at the drive roll both ends
Axis passes through the bearing block being arranged on the inside of the rack and is mounted on the rack.
Preferably, the projecting shaft of described drive roll one end extends to the Shelf External, and is equipped with connecting flange, the company
Acting flange one end is equipped with transmission shaft, and described transmission shaft one end is equipped with servo motor.
Preferably, the drive roll is roll.
Preferably, the inside both ends in the connecting shaft positioned at the driven voller are successively arranged oil sealing and activity from outside to inside
Bearing.
Preferably, the driven voller is at least provided with two groups.
By adopting the above technical scheme, driven voller is mounted on to the guide groove of mounting base by the folk prescription spindle nose at connecting shaft both ends
It is interior, and offset with the spring stretched into guide groove, downward pressure is exported to folk prescription spindle nose by the cylinder at the top of mounting base
It supports spring to compress downwards, driven voller is made to clamp plate, once emergency stop situation occur causes to shut down, cylinder stops pneumatic output,
Driven voller is reset to initial position by the recoil of spring state that affranchises, so that pinch roller will not wear generation processing plate, is avoided
The waste of time and materials is discarded and caused to the plate processed before, and structure is simple, easy to install, easy to maintain.

Specific embodiment
Specific embodiment of the present utility model is described further with reference to the accompanying drawing.It should be noted that
The explanation of these embodiments is used to help to understand the utility model, but does not constitute the restriction to the utility model.This
Outside, technical characteristic involved in the various embodiments of the present invention described below is as long as they do not conflict with each other
It can be combined with each other.
Combine a kind of shown, snowflake sand machine live-roller fast lifting structure picture 1-4, including rack 1, mounting base 2, driven
Roller 3 and cylinder 5.Wherein, mounting base 2 is mounted on 1 two sides of rack, and mounting base 2 is equipped with guide groove 201, the lower section of guide groove 201
It is equipped with holding tank 202 positioned at 2 bottom of mounting base, holding tank 202 is connected with guide groove 201, is provided with spring in holding tank 202
203 or other return springs, and stretched in a free state into guide groove 201;3 center of driven voller is equipped with connecting shaft 4, even
4 both ends of spindle are equipped with folk prescription spindle nose 401, and driven voller 3 is mounted on guide groove 201 by the folk prescription spindle nose 401 at 4 both ends of connecting shaft
It is interior, and 401 bottom end of folk prescription spindle nose is mutually supported with 203 top of spring;Cylinder 5 is arranged in 2 bottom of mounting base, and the output of cylinder 5
End extends to inside guide groove 201, and is directed at the upper surface of folk prescription spindle nose 401, and downward pressure is exported to folk prescription spindle nose 401,
It drives driven voller 3 to move downward, compresses spring 203 downwards, once emergency stop situation occur causes to shut down, cylinder 5 stops pneumatically
Output, spring 203 springs back the state that affranchises and driven voller 3 is reset to initial position, so that pinch roller will not wear generation processing
Plate.
The lower section that driven voller 3 is corresponded in rack 1 is equipped with drive roll 6, and drive roll 6 is roll, the projecting shaft at 6 both ends of drive roll
Bearing block 601 by the way that 1 inside of rack is arranged in is mounted in rack 1, during installation, can pass through the installation site of drive roll 6
For benchmark face, facilitate the origin reference location of mounting base 2, is easily installed and safeguards.
The projecting shaft of 6 one end of drive roll extends to outside rack 1, and is equipped with connecting flange 602,602 one end of connecting flange
Equipped with transmission shaft 7,7 one end of transmission shaft is equipped with servo motor 8.
Inside both ends in connecting shaft 4 positioned at driven voller 3 are successively arranged oil sealing 402 and live bearing 403 from outside to inside, make
Driven voller 3 rotates more flexible, steady, improves service life.
For driven voller 3 at least provided with two groups, optimal case can be used four groups.
By adopting the above technical scheme, driven voller 3 is mounted on mounting base 2 by the folk prescription spindle nose 401 at connecting shaft both ends
