Description

Technical Field

[0001] The utility model relates to the technical field of workpiece powder molding, in particular to a powder shaking device for a powder molding machine. Background Art

[0002] The plastic powder coating methods include spraying and dipping. The dipping coating is to apply liquid polymer or plastic to the surface of the metal workpiece by dipping. When the workpiece is taken out of the dipping machine, the plastic powder on the surface close to the metal surface tends to melt and set, while the plastic powder closer to the outside cannot be melted into a plastic layer because the temperature influence of the workpiece itself is weakened. At this time, the plastic powder on the outside needs to be removed as soon as possible to avoid affecting the quality of the plastic layer.

[0003] For example, the Chinese invention patent with patent number 202110357091.4 provides a clamping vibration device for a plastic-impregnated bearing retainer, wherein a vibrating member is arranged between the bearing member and the radial displacement mechanism, and the vibrating member includes a vibration motor and a vibration cylinder. When the device is in use, the vibration motor and the vibration cylinder drive the workpiece to achieve regular swinging to remove the plastic powder on the surface of the workpiece as quickly as possible.

[0004] However, the powder shaking structure in the existing plastic powder machines mostly realizes powder shaking through a vibration motor, but the shaking amplitude of this powder shaking method is small, and the powder on the outside of the workpiece cannot be shaken off quickly and sufficiently, resulting in a part of the powder still adhering to the workpiece, resulting in a decrease in the quality of the plastic layer. Utility Model Content

[0005] In view of the shortcomings of the prior art, the utility model proposes a powder shaking device for a plastic powder machine to solve the technical problem raised in the above background technology that the powder shaking structure in the existing plastic powder machines mostly realizes powder shaking through a vibration motor, but the shaking amplitude of this powder shaking method is small, and the powder on the outside of the workpiece cannot be shaken off quickly and sufficiently, resulting in a part of the powder still adhering to the workpiece, resulting in a decrease in the quality of the plastic layer.

[0006] To achieve the above purpose, the utility model provides the following technical solutions: a powder shaking device for a plastic powder machine, used to shake a hanger walking on a track, the hanger can be lifted and lowered on the track, and the track is installed on the installation plane, including:

[0007] A mounting column, fixedly arranged on the mounting plane, wherein a lifting plate is provided on the mounting column so as to be liftable;

[0008] A connecting assembly is arranged on the hanger, and when the hanger moves under the lifting plate, it is connected to the lifting plate through the connecting assembly;

[0009] A lifting block is arranged at the bottom of the lifting plate; and

[0010] The driving motor is arranged on the installation plane. The output shaft of the driving motor is provided with a lifting wheel. The lifting wheel is provided with a protrusion. The lifting wheel abuts against the lifting block.

[0011] In a preferred embodiment, the connection assembly includes:

[0012] A connecting frame, arranged on the hanger; and

[0013] A receiving frame is arranged at the bottom of the lifting plate, and when the hanger moves along the track, the connecting frame can pass through the receiving frame.

[0014] In a preferred embodiment, an inclined guide plate is provided at the end of the connecting frame, and a chamfer is provided at the end of the guide plate.

[0015] In a preferred embodiment, a limit block is provided at the end of the mounting column, and the lifting plate is slidably sleeved on the mounting column.

[0016] In a preferred embodiment, a fixing seat is slidably sleeved on the mounting column along its axis, the fixing seat is fixed to the mounting surface by bolts, and a threaded limit plate is provided at the end of the mounting column, and the limit plate is clamped in the fixing seat.

[0017] In a preferred embodiment, a buffer pad is provided between the limiting plate and the inner side of the fixing seat.

[0018] Compared with the prior art, the utility model has the following beneficial effects:

[0019] When the device is in use, the hanger can be controlled to move on the track, and the workpiece is hung on the hanger for plastic powder. When the hanger moves under the lifting plate, the hanger can be connected to the lifting plate through the connecting component. The hanger can be driven to move up and down during the lifting of the lifting plate. At this time, the lifting wheel is driven to rotate by starting the driving motor. During the rotation, the lifting wheel drives the lifting block and the lifting plate to rise through the abutment between the protrusion and the lifting block, until the protrusion is separated from the lifting block and drives the lifting plate to descend under the hanger's own gravity. When the lifting plate descends to the limit position, the hanger shakes, and the powder on the outside of the workpiece is shaken off by inertia. The vibration force applied to the workpiece is large, which can fully shake off the excess powder on the workpiece, thereby effectively improving the quality of the plastic layer.

A connecting assembly is arranged on the hanger 102, and the hanger 102 is connected to the lifting plate 201 through the connecting assembly when the hanger 102 moves under the lifting plate 201. The connecting assembly includes a connecting frame 103 arranged on the hanger 102, and a receiving frame 202 is arranged at the bottom of the lifting plate 201. When the hanger 102 moves along the track 101, the connecting frame 103 can pass through the receiving frame 202.

[0033] By controlling the hanger 102 to move along the track 101, when the hanger 102 moves to the bottom of the lifting plate 201, the connecting frame 103 is clamped on the inner side of the receiving frame 202, and the lifting and lowering of the lifting plate 201 can be controlled to drive the hanger 102 to move up and down as a whole. An inclined guide plate 104 is provided at the end of the connecting frame 103, and a chamfer is provided at the end of the guide plate 104. The connecting frame 103 can be guided into the receiving frame 202 by the cooperation of the inclined guide plate 104 and the chamfer, so that the connecting frame 103 can smoothly enter the receiving frame 202 even if the position of the connecting frame 103 deviates, thereby improving the practicality of the device.

[0034] like Figure 3 As shown, in this embodiment, a lifting block 203 is provided at the bottom of the lifting plate 201, a driving motor 301 is provided on the mounting plane, a lifting wheel 302 is provided on the output shaft of the driving motor 301, a protrusion 303 is provided on the lifting wheel 302, and the lifting wheel 302 abuts against the lifting block 203. The driving motor 301 can be controlled to start and drive the lifting wheel 302 to rotate, and the lifting wheel 302 can be lifted up by the abutment of the protrusion 303 with the lifting block 203 during the rotation process, so as to drive the entire hanger 102 and the workpiece on the hanger 102 to rise, until the protrusion 303 is separated from the lifting block 203, and the hanger 102 is controlled to move downward under the dead weight of the hanger 102 and the workpiece, until the lifting plate 201 abuts against the limit block 402, so as to generate a large vibration on the workpiece, so as to quickly shake off the excess powder on the workpiece.

[0035] like Figure 3 As shown, in this embodiment, a fixing seat 405 is slidably sleeved on the mounting column 401 along its axis, and the fixing seat 405 is fixed to the mounting surface by bolts.

The hanger 102 can be driven to rise and fall during the lifting and lowering of the lifting plate 201. At this time, the lifting wheel 302 is driven to rotate by starting the driving motor 301. During the rotation, the lifting wheel 302 drives the lifting block 203 and the lifting plate 201 to rise through the contact between the protrusion 303 and the lifting block 203, until the protrusion 303 is separated from the lifting block 203 and drives the lifting plate 201 to descend under the weight of the hanger 102 itself. When the lifting plate 201 descends to the limit position, the hanger 102 shakes, and the powder on the outside of the workpiece is shaken off by inertia, and the vibration force applied to the workpiece is large, which can fully shake off the excess powder on the workpiece, thereby effectively improving the quality of the plastic layer.
