Description

Technical Field

[0001] This utility model relates to a ash pan press, and in particular to a cleaning device for the ash pan press. Background Technology

[0002] Magnesia ash pans are typically produced by pressing magnesia raw materials into shape using a press. This press has an upper mold and a lower mold. The lower mold is usually a concave mold, fixedly connected to the equipment frame; the upper mold is usually a convex mold, moved up and down by a hydraulic cylinder to achieve closure / separation with the lower mold. The upper mold usually has multiple raised mold blocks arranged in a row, pressing multiple pans at a time. After pressing, some raw material dust particles will adhere to the outer wall and bottom surface of the mold blocks in the upper mold. These need to be cleaned with a brush; otherwise, long-term accumulation will affect the quality of the pressed pans. Currently, this step is generally done manually, which is inconvenient and affects processing efficiency. Utility Model Content

[0033] Please see Figure 1 A cleaning device for a ash pan press includes a mounting frame 1, a first drive unit 2, a mounting block 3, and a brush unit 4.

[0034] Mounting bracket 1 has an upper mounting portion 1a and a lower mounting portion 1b, which are spaced apart in a first horizontal direction. More specifically, both the upper mounting portion 1a and the lower mounting portion 1b can be a vertical plate, and a horizontal plate connecting the two is provided between the bottom of the upper mounting portion 1a and the top of the lower mounting portion 1b. The size of the horizontal plate determines the size of the gap between the upper mounting portion 1a and the lower mounting portion 1b.

[0035] The upper mounting part 1a is used to install the cleaning device on the ash pan press, specifically at one of the vertical sides of the upper mold. Additionally, a triangular rib can be provided between the upper mounting part 1a and the horizontal plate to enhance stability.

[0036] The first drive unit 2 is a linear drive and is mounted on the lower mounting part 1b. The output end of the first drive unit 2 extends and retracts in a first direction, passing through the upper mounting part 1a. That is, the first drive unit 2 is mounted on the side of the lower mounting part 1b away from the gap, and the output end extends out from the lower mounting part 1b, with the entire stroke of the output end covering the upper mold.

[0037] Mounting block 3 is fixedly connected to the output end of the first drive unit 2.

[0038] The brush part 4 is mounted on the mounting block 3. More specifically, the brush part 4 includes a brush plate 4a for mounting to the mounting block 3 and brush bristles 4b disposed on the brush plate 4a. The mounting between the brush plate 4a and the mounting block 3 can be a fixed connection. When the first drive part 2 is in the retracted state, the mounting block 3 and the brush part 4 are positioned between the upper mounting part 1a and the lower mounting part 1b. That is, at this time, the cleaning device will not interfere with the fit between the upper mold and the lower mold, and the ash press can work normally. With the brush bristles 4b facing upwards, after the upper mold is lifted, the first drive part 2 extends, driving the brush bristles 4b past the upper mold to brush off dust particles on the upper mold, thus cleaning the upper mold.

[0039] In some embodiments, the first drive unit 2 may be a cylinder.

[0040] In some embodiments, the first drive unit 2 can be a planetary roller screw type electric cylinder.

[0041] Compared to pneumatic cylinders, planetary roller screw-type electric cylinders allow for smoother movement of the 4b bristles and better control over their speed.

[0042] Please see Figure 2 In some embodiments, the cleaning device further includes a second drive unit 5. The brush part 4 and the mounting block 3 are mounted such that the brush part 4 is slidably connected to the mounting block 3 along a second direction perpendicular to the first direction and horizontal. More specifically, a linear guide rail is fixedly connected to the mounting block 3, and multiple mounting sliders are matched to the linear guide rail; the brush plate 4a is fixedly connected to these mounting sliders. The second drive unit 5 is mounted on the mounting block 3 and is used to drive the brush part 4 to swing back and forth.

[0043] As the first drive unit 2 extends and drives the brush bristles 4b through the upper mold, the second drive unit 5 simultaneously drives the brush unit 4 to swing back and forth, improving the cleaning effect on the upper mold.

[0044] In some embodiments, the second drive unit 5 may include a compression spring and a vibration motor 5b. The compression spring is disposed between the brush plate 4a and the mounting block 3, causing the brush plate 4a to abut against a protrusion on the mounting block 3, with the brush portion 4 correspondingly positioned on one side of the protrusion. The vibration motor 5b is mounted on the brush plate 4a, and its operation, in conjunction with the compression spring, drives the brush portion 4 to oscillate back and forth.

[0045] Please see Figure 3 and Figure 4 In some embodiments, the second drive unit 5 may include a crank 5a, a motor 5b, and a connecting strip 5c. The motor 5b is fixedly connected to the mounting block 3. More specifically, the mounting block 3 is provided with a slot for mounting the motor 5b, and a planetary gear reducer may be connected to the motor 5b to reduce the output speed of the motor 5b to a suitable range, so that the oscillation frequency of the brush is appropriate. The crank 5a is driven to rotate by the motor 5b, that is, the crank 5a is fixedly connected to the output shaft. The connecting strip 5c is connected to the crank 5a and the brush part 4 to form a crank 5a slider. More specifically, a connecting block 5d may be fixedly connected to the brush plate 4a, one end of the connecting strip 5c is hinged to the crank 5a, and the other end is hinged to the connecting block 5d.

[0046] Compared to the compression spring and vibration motor 5b method, the crank 5a, motor 5b and connecting bar 5c method is more convenient to control, and the back-and-forth swaying frequency of the brush part 4 is also more uniform.

[0047] Please see Figure 5 and Figure 6 In some embodiments, the cleaning device further includes several suction ports 6, a vacuum cleaner 7, a hose 8, and a cable chain 9. Several suction ports 6 are disposed on a brush plate 4a. More specifically, the brush plate 4a is hollow, and the bottom plate 4a1 of the brush plate 4a is fixedly connected to a pipe 6a by welding or an Ω-shaped clip. The pipe 6a has multiple upward-facing inlets, which are the suction ports 6. The bristles 4b are in multiple groups, with gaps between adjacent groups of bristles 4b. The top plate of the brush plate 4a has holes corresponding to these gaps for the suction ports 6 to enter. The vacuum cleaner 7 is placed on one side of the dust collector. The hose 8 connects the vacuum cleaner 7 and the suction ports 6. More specifically, the pipe 6a has a downward-facing outlet, and the hose 8 connects this outlet to the vacuum cleaner 7. The cable chain 9 is used for the hose 8 to pass through, keeping the hose 8 neat during the movement of the brush section 4. More specifically, one end of the cable chain 9 is mounted to the mounting bracket 1, and the other end is mounted to the mounting block 3 or the brush plate 4a.

[0048] During the cleaning of the upper mold, the brush section 4 can activate the vacuum cleaner 7. The fan inside the vacuum cleaner 7 causes the dust particles and air to enter through the suction port 6, pass through the hose 8, and then into the vacuum cleaner 7. The dust particles are then intercepted by the filter inside the vacuum cleaner 7, improving the cleaning effect.

[0049] Please see Figure 5 In some embodiments, the first end of the drag chain 9 is mounted on the mounting bracket 1, and the second end is mounted on the mounting block 3.

[0050] The length of the hose 8 between the outlet of the pipe 6a and the second end of the drag chain 9 is reasonably set so that it has a certain margin, which can be more conveniently combined with the embodiment in which "the cleaning device also includes a second drive unit 5".
