Description

Technical Field

[0001] The utility model relates to the technical field of plate blanking, in particular to a plate uniform blanking device. Background Art

[0002] The existing plate transport rack is directly placed at one end of the plate feeder. After the plate feeder conveys the plate from one end of the feeder, the plate will continue to move forward due to inertia, and at the same time, due to the effect of gravity, the plate will tend to fall. The combined effect of these two forces will cause the plate to fall quickly onto the transport rack. Since the plate falls quickly under the effect of gravity, each time a new plate falls, it will cause an impact on the plates already stacked on the transport rack, which will cause surface damage due to collision between the plates. In addition, in the process of falling, the plates are affected by inertia and gravity, making it difficult to fall evenly on the transport rack, which will cause the plates to be stacked unevenly and cause the plate to tilt. In the process of transportation, the plates are easily caused to slide, affecting the safety of transportation.

[0024] As an embodiment of the utility model, the transmission unit also includes a transmission rod 123; the output shaft of the drive motor 12 is provided with a groove 124; the transmission rod 123 is slidably and sealedly connected in the groove 124; the transmission rod 123 is fixedly connected to the bottom of the groove 124 by a support spring 125; the bottom of the groove 124 is inlaid with an electromagnetic plate 126; the end of the transmission roller 11 close to the groove 124 is provided with a card groove 112 that matches the transmission rod 123; the output shaft surface of the drive motor 12 is provided with a fixed groove 15 connected to the groove 124; a fixed rod 151 is slidably and sealedly connected in the fixed groove 15; the fixed rod 151 is fixedly connected to the groove wall of the fixed groove 15 by a tower spring 152; the surface of the transmission belt 135 is provided with a round hole 153 that matches the fixed rod 151.

[0025] As an embodiment of the present invention, a feed port 16 is provided on a side of the plate storage box 13 away from the machine body 1 ; a baffle 161 is provided on one side of the feed port 16 ; and the baffle 161 is rotatably connected to the plate storage box 13 .

[0026] As an implementation mode of the present utility model, a sleeve 17 is fixedly connected to the surface of the driving roller 11; the sleeve 17 is made of silicone material.

[0027] As an embodiment of the present invention, a thread groove 171 is formed on the surface of the sleeve 17; the number of the thread grooves 171 is two; the two thread grooves 171 are located at both ends of the sleeve 17; the thread directions of the two thread grooves 171 are opposite;

[0028] After the existing plate unloading machine conveys the plate from one end of the unloading machine, the plate will continue to move forward due to inertia, and at the same time, due to the effect of gravity, the plate will tend to fall; the combined effect of these two forces will cause the plate to fall quickly onto the transport rack. Since the plate falls quickly under the effect of gravity, each time a new plate falls, it will cause an impact on the plates already stacked on the transport rack, which will cause surface damage due to collision between the plates. In addition, during the falling process, the plates are affected by inertia and gravity, making it difficult to fall evenly on the transport rack, which will cause the plates to be stacked unevenly and cause the plate to tilt. In the process of transportation, the plates are easily caused to slide, affecting the safety of transportation;

[0029] During operation, when the plate unloading machine needs to convey the plate, the driving motor 12 drives the transmission roller 11 connected thereto to rotate; so that the transmission roller 11 can drive the transmission gear 111 fixed thereto to rotate, so that the transmission gear 111 can push the entire conveyor belt 121 to rotate around through the tooth grooves 122 of the inner ring of the conveyor belt 121, so that during the rotation of the conveyor belt 121, it can drive the multiple transmission rollers 11 at the upper end of the machine body 1 to rotate, and then the transmission roller 11 can push the plate placed on the upper end to move towards the plate storage box 13 during the rotation; in order to prevent the plate from reducing the friction between it and the transmission roller 11 due to its smooth surface, the utility model sets a sleeve 17, so that the sleeve 17 made of silicone material is not only soft in texture but also friction-resistant. The large friction coefficient enables the plate on the surface of the transmission roller 11 to generate pressure on the sleeve 17, so that the sleeve 17 is squeezed and deformed, so that the contact area between the sleeve 17 and the plate is increased, and then the friction between the sleeve 17 and the plate is increased, and the pushing effect of the transmission roller 11 on the plate is improved; since the transmission belt 135 is made of PTFE material, the transmission belt 135 is not driven by the output shaft of the driving motor 12 at this time; when the plate moves to the top of the plate storage box 13, the plate will contact the roller 14, and is located above the plate storage box 13 under the support of the roller 14, so that the plate is in contact with the side of the plate storage box 13 away from the body 1 under the action of inertia; at this time, the electromagnetic plate 126 is first controlled to be energized, so that the electromagnetic plate 126 absorbs the transmission rod 123 to squeeze The support spring 125 is pressed into the groove 124; at this time, the transmission rod 123 can extend out of the slot 112 and separate from the transmission roller 11, and in the process of the transmission rod 123 entering the slot 124; the transmission rod 123 will squeeze the air in the slot 124, so that the air in the slot 124 is compressed and enters the fixed slot 15; at this time, the air entering the fixed slot 15 pushes the fixed rod 151 to stretch the tower spring 152 out of the fixed slot 15; at this time, if the fixed rod 151 is blocked by the transmission belt 135, until the drive motor 12 rotates, the drive motor 12 can drive the fixed rod 151 to rotate through the output shaft, so that the fixed rod 151 rotates to match the circular hole 153 on the surface of the transmission belt 135, and at this time, the fixed rod 151 is pushed out of the fixed slot 151 by the air pressure. The fixed groove 15 enters the circular hole 153, so that the driving motor 12 pushes the hole wall of the circular hole 153 through the fixing rod 151 to drive the entire transmission belt 135 to circle, so that the transmission belt 135 drives the bevel gear shaft 133 connected thereto to rotate, so that the bevel gear shaft 133 can drive the bevel gear ring 134 meshing therewith to rotate, so that the bevel gear ring 134 drives the screw rod 132 fixed thereto to rotate, so that the screw rod 132 drives the lifting plate 131 connected thereto with a spiral transmission to rise, so that when the lifting plate 131 rises to a position close to the roller 14, the control electromagnetic sheet 142 is energized, so that the electromagnetic sheet 142 generates a magnetic adsorption force on the side wall of the storage plate box 13, thereby driving the entire roller 14 to squeeze and push the spring 143 to move in a direction close to the storage plate box 13;The rollers 14 on both sides of the plate are in sliding contact with the plate until the rollers 14 on both sides of the plate pass over the plate. At this time, the plate falls onto the lifting plate 131 under the action of gravity. Since the distance between the lifting plate 131 and the plate is small, the lifting plate 131 has a small impact force on the plate stacked below, thereby reducing the problem of impact damage to the plate below. After the plates are stacked, the top plate is located between the two rollers 14. By controlling the electromagnetic sheet 142 to cut off power, the push spring 143 pushes the rollers 14 to move away from each other, so that the rollers 14 can push the two sides of the plate, thereby pushing the stacked plates to be stacked neatly. To ensure that the plate can be located at the center of the plate storage box 13 when it is transported to the rollers 14, that is, the plate and the two sides are close to each other. The spacing between the edges and the rollers 14 on both sides is the same. The present invention provides thread grooves 171 on the surface of the sleeve 17, so that the thread grooves 171 at both ends of the sleeve 17 can push the plate on the surface of the upper sleeve 17 toward the center, that is, if the plate is not placed at the center of the machine body 1, but deviates to one side, the contact area between the plate and the thread on the deviated side increases, so that the pushing force of the thread on the deviated side on the plate toward the center increases, and then the plate moves toward the center, thereby avoiding the plate from being deviated to one side, so that the roller 14 that is far away first passes over the plate, thereby ensuring that the plate can fall horizontally, so as to increase the contact area between the plates, avoid stress concentration and damage to the lower plate; thereby ensuring the stacking quality of the plates;

[0030] By providing the feed port 16 and the baffle 161, during the process of unloading the plates, the user can lift the baffle 161 to push the plate transport rack into the plate storage box 13 through the feed port 16. After the plates are stacked, the baffle 161 is opened to pull the transport rack with the plates stacked in the plate storage box 13 out of the feed port 16, and replace the transport rack with a new one to stack the plates in the plate storage box 13. Therefore, there is no need to replace the plate storage box 13, which reduces the production quantity of the plate storage box 13 and the production cost, thereby further improving the practicality of the present invention.

[0031] The utility model arranges the screw rod 132 so that the screw rod 132 can drive the lifting plate 131 to descend, so that the lifting plate 131 can reduce the falling distance of the plate by rising, reduce the impact of the newly fallen plate on the plates already stacked on the transport rack, thereby preventing surface damage caused by collision between the plates, and the roller 14 can push the newly fallen plate to align with the plates stacked below, thereby avoiding the problem of plate tilting, making it difficult for the plate to slip during transportation, thereby improving transportation safety.
