Abstract
Description
Technical Field
[0001] This utility model relates to a material tray filling device, and more particularly to an automatic powder spreading device with a leveling function. Background Technology
[0002] In existing tray filling equipment, when powder is fed, the external screw feeder directly delivers the powder to the tray through the inlet. This easily leads to inconsistent powder heights in different areas of the tray, especially in the central area (i.e., the position perpendicular to the inlet), where powder tends to accumulate. This can affect the processing effect of the powder in subsequent processes (such as baking and calcination), thus impacting product quality and causing problems for manufacturers. To solve this problem, some manufacturers manually scrape the powder off the tray, but this increases labor costs and reduces the company's economic efficiency. Utility Model Content
[0003] Therefore, it is necessary to provide an automatic powder spreading device with a leveling function to address the shortcomings of existing technologies.
[0004] An automatic powder spreading device with a leveling function is used to convey a fixed amount of powder into a material tray and level the powder in the tray. It includes a filling hopper, a feeding line, a leveling mechanism, a weighing module, and a lifting mechanism. The feeding line, inlet nozzle, leveling mechanism, weighing module, and lifting mechanism are all located within the filling hopper. The inlet nozzle and leveling mechanism are positioned above the feeding line. The weighing module is mounted on the lifting mechanism. The lifting mechanism vertically adjusts the position of the weighing module, causing its top surface to extend above or below the upper surface of the feeding line. The feeding line horizontally adjusts the material tray flowing into the filling hopper, causing it to flow past the inlet nozzle and into the position above the weighing module. The outlet of the inlet nozzle is flat and duckbill-shaped, and the flat surface of the outlet is perpendicular to the feeding direction of the feeding line. The leveling mechanism includes a bracket, a drive assembly, and a scraper. The drive assembly adjusts the scraper in the forward and backward direction.
[0005] In one embodiment, the filling chamber includes several chambers mounted on the frame body, a first pneumatic door mounted on the frontmost chamber, and a second pneumatic door mounted on the rearmost chamber. The chambers are connected end to end and enclose an inner space that extends from front to back.
[0006] In one embodiment, the top and bottom of the silo are conical. The automatic powder spreading equipment with a leveling function also includes a dust removal pipe assembly. The dust removal pipe assembly includes several branch pipes, which are respectively connected to the top of different silos. The dust removal pipe assembly is connected to an external negative pressure device.
[0007] In one embodiment, the bottom of the silo is provided with a discharge port, and the filling silo is also provided with a valve installed at the bottom of the silo and cooperating with the discharge port.
[0008] In one embodiment, the filling chamber is further provided with an inner positioning frame, and the feeding line, the leveling mechanism and the lifting mechanism are all installed on the inner positioning frame.
[0009] In one embodiment, the feeding line consists of two separate sub-feeding lines, one of which is located below the feed nozzle and the other is located below the leveling mechanism.
[0010] In one embodiment, the system further includes a feeding module, a screw feeder, and a control switch. The screw feeder extends into the filling chamber, and the control switch connects the screw feeder to the feed nozzle.
[0011] In one embodiment, the feeding module includes a support frame, a metering chamber, a plurality of support seats mounted on the metering chamber, and a plurality of weighing sensors mounted on the support frame. The support seats correspond one-to-one with the weighing sensors, and the support seats press down on the weighing sensors. The feed inlet at the top of the metering chamber is connected to an external powder storage tank, and the screw feeder is mounted on the metering chamber.
[0012] In one embodiment, the control switch is a pneumatic disc valve.
[0013] In one embodiment, the drive assembly includes a first positioning seat group and a second positioning seat group mounted on a bracket, a first linkage rod movably mounted on the first positioning seat group, a second linkage rod movably mounted on the second positioning seat group, a first drive sprocket mounted on the first linkage rod, a second drive sprocket mounted on the second linkage rod, a chain sleeved on the first drive sprocket and the second drive sprocket, and a scraper motor connected to the first linkage rod. The scraper is mounted on the chain. During forward or reverse rotation, the scraper motor drives the chain to rotate forward or reverse through the first linkage rod, the second linkage rod, the first drive sprocket, and the second drive sprocket.
[0014] The beneficial effects of this automatic powder spreading device with a leveling function are as follows: by setting up a leveling mechanism, a weighing module and a lifting mechanism, the weighing module is installed on the lifting mechanism. The lifting mechanism drives the weighing module to adjust its position in the vertical direction. When the material tray flows into the area above the weighing module, the lifting mechanism drives the weighing module to rise and press against the bottom of the material tray. The material tray is then separated from the feeding line. The leveling mechanism levels the powder in the material tray, making the powder spreading thickness in the material tray uniform, effectively ensuring the quality of the powder on the material tray during subsequent processing, and making it highly practical.

[0026] Please see Figures 1 to 6This utility model provides an automatic powder spreading device with a leveling function, used to convey a fixed amount of powder into a material tray 200 and level the powder in the material tray 200. The automatic powder spreading device with leveling function includes a frame body 10, a feeding module 20, a filling bin 30, a dust removal pipe assembly 40, a screw feeder 50, a feed nozzle 60, a control switch 70, a feeding line 80, a leveling mechanism 90, a weighing module 100, and a lifting mechanism 110. The filling bin 30 is installed on the frame body 10. The feeding line 80, feed nozzle 60, leveling mechanism 90, weighing module 100, and lifting mechanism 110 are all located within the filling bin 30. The leveling mechanism 90 is located above the feeding line 80. The weighing module 100 is mounted on the lifting mechanism 110. The lifting mechanism 110 drives the weighing module 100 to adjust its position in the vertical direction, so that the top surface of the weighing module 100 extends into the upper part of the feeding line or moves down to the lower part of the upper surface of the feeding line. The screw feeder 50 extends into the filling hopper 30. The control switch 70 connects the screw feeder 50 and the feed nozzle 60. The feeding line adjusts the material tray 200 flowing into the filling hopper 30 in the horizontal direction, so that the material tray 200 flows through the lower part of the feed nozzle 60 and enters the position above the weighing module 100. The dust removal pipe assembly 40 is connected to the external negative pressure device.
[0027] The feeding module 20 includes a support frame 21, a metering chamber 22, several support seats 23 mounted on the metering chamber 22, and several weighing sensors 24 mounted on the support frame 21. Each support seat 23 corresponds to a weighing sensor 24, and the support seat 23 presses down on the weighing sensor 24. The feed inlet at the top of the metering chamber 22 connects to an external powder storage tank. The screw feeder 50 is mounted on the metering chamber 22, and the discharge port at the bottom of the metering chamber 22 is connected to the feed inlet of the screw feeder 50. The control switch 70 connects the feed inlet of the feed nozzle 60 and the discharge port of the screw feeder 50. The control switch 70 controls the opening and closing of the flow channel. In this embodiment, the control switch 70 is a pneumatic disc valve. In addition, the discharge port of the feed nozzle 60 is arranged in a flat duckbill shape, and the flat surface of the discharge port is perpendicular to the feeding direction of the feeding line 80.
[0028] The filling silo 30 includes several silo bodies 31 mounted on the frame body 10, a first pneumatic door 32 mounted on the frontmost silo body 31, and a second pneumatic door 33 mounted on the rearmost silo body 31. The silo bodies 31 are connected end to end, forming a front-to-back extending inner space 35. The top and bottom of each silo body 31 are conical. The dust removal pipe assembly 40 includes several branch pipes 41, which are respectively connected to the top positions of different silo bodies 31. The bottom of each silo body 31 is provided with a discharge port (not shown). The filling silo 30 is also provided with a valve (not shown) installed at the bottom of the silo body 31 and cooperating with the discharge port. Powder falling into the bottom of the silo body 31 can be discharged from the discharge port and the valve. In addition, the filling silo 30 is also provided with an inner positioning frame 34, on which the feeding line 80, the leveling mechanism 90, and the lifting mechanism 110 are all mounted.
[0029] In this embodiment, the feeding line 80 consists of two separate sub-feeding lines 80. One sub-feeding line 81 is located below the feed nozzle 60, and the other sub-feeding line 81 is located below the scraping mechanism 90. Each sub-feeding line 81 includes a roller assembly 82, a feeding belt 83, and a feeding motor 84. The feeding motor 84 drives the feeding belt 83 to rotate forward or backward through the roller assembly 82, thereby causing the feeding belt 83 to drive the material tray 200 to feed forward or backward. Furthermore, the feeding motor 84 is located on the outside of the hopper 31, which helps prevent dust from entering the motor and improves its service life.
[0030] The scraping mechanism 90 includes a bracket 91, a drive assembly (not shown in the figure), and a scraper 910. The drive assembly adjusts the scraper 910 in the front-to-back direction. The drive assembly includes a first positioning seat group 92 and a second positioning seat group 93 mounted on the bracket 91; a first linkage rod 94 movably mounted on the first positioning seat group 92; a second linkage rod 95 movably mounted on the second positioning seat group 93; a first drive sprocket 96 mounted on the first linkage rod 94; a second drive sprocket 97 mounted on the second linkage rod 95; a chain 98 sleeved on the first drive sprocket 96 and the second drive sprocket 97; and a scraping motor 99 connected to the first linkage rod 94. The scraper 910 is mounted on the chain 98. During forward or reverse rotation, the scraping motor 99 drives the chain 98 to rotate forward or reverse via the first linkage rod 94, the second linkage rod 95, the first drive sprocket 96, and the second drive sprocket 97. The scraping motor 99 is also located on the outside of the hopper 31, which helps prevent dust from entering the motor and improves its service life.
[0031] When it is necessary to fill the material tray 200, open the first pneumatic door 32, push the empty material tray 200 into the inner space 35 of the silo 31, and close the first pneumatic door 32. The feed line adjusts the material tray 200 flowing into the filling silo 30 horizontally so that the material tray 200 flows under the feed nozzle 60. When the material tray 200 flows under the feed nozzle 60, the screw feeder 50 transfers the powder to the material tray 200 through the feed nozzle 60 and spreads the powder on the material tray 200 during the movement. The metering silo 22, support base 23, screw feeder 50, control switch 70 and feed nozzle 60, which are connected as a whole, press down on the weighing sensor 24. The feeding module 20 calculates the weight of the powder flowing into the material tray 200 through the weighing sensor 24. When the weight reaches the set value, the control switch 70 is turned off.
[0032] After the powder is spread, the material tray 200 enters another sub-feeding line 81. The other sub-feeding line carries the material tray 200 to a position above the weighing module 100. The lifting mechanism 110 lifts the weighing module 100 and presses it against the bottom of the material tray 200. The material tray 200 detaches from the sub-feeding line, and the scraper 910 extends into the material tray 200. The drive component of the leveling mechanism 90 drives the scraper 910 to move back and forth, leveling the powder in the material tray 200. The weighing module 100 weighs the powder in the material tray 200. If the weight is not up to standard, the feeding line 80 carries the material tray 200 back to below the feed nozzle 60 to continue replenishing the material. After replenishment, the material tray 200 is weighed again and leveled. If the weight is up to standard, the sub-feeding line 81 moves the material tray 200 to a position close to the second pneumatic door 33, opens the second pneumatic door 33, and then removes the material tray 200. During the powder spreading and leveling process, the external negative pressure device extracts dust from the inner space 35 of the filling chamber 30 through the dust removal pipe group 40.
[0033] The beneficial effects of this utility model of an automatic powder spreading device with a leveling function are as follows: by setting up a leveling mechanism 90, a weighing module 100 and a lifting mechanism 110, the weighing module 100 is installed on the lifting mechanism 110. The lifting mechanism 110 drives the weighing module 100 to adjust its position in the vertical direction. When the material tray 200 flows into the area above the weighing module 100, the lifting mechanism 110 drives the weighing module 100 to rise and press against the bottom of the material tray 200. The material tray 200 is then separated from the feeding line. The leveling mechanism 90 levels the powder in the material tray 200, making the powder spreading thickness in the material tray 200 uniform, effectively ensuring the quality of the powder on the material tray 200 during subsequent processing, and making it highly practical.
[0034] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0035] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
