Detailed Implementation

[0056] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that the description of these embodiments is intended to aid in understanding the invention, but does not constitute a limitation thereof. The specific structural and functional details disclosed herein are merely for describing exemplary embodiments of the invention. However, the invention can be embodied in many alternative forms and should not be construed as being limited to the embodiments described herein.

[0057] like Figure 1 As shown, according to an embodiment of this disclosure, a hydraulic control device 100 for a fabric distributor is provided, characterized in that it includes: a belt conveyor 110; a hydraulic drive unit connected to the belt conveyor 110 for driving the belt conveyor 110 to reciprocate; a valve body assembly for controlling the flow rate of hydraulic oil supplied from an oil tank 180 to the hydraulic drive unit; a position sensor assembly for detecting the switching signal of the valve body assembly; and a controller 170 for receiving the switching signal sent by the position sensor assembly, controlling the hydraulic drive unit to start when the switching signal is determined to be correct, and controlling the hydraulic drive unit to stop when the switching signal is determined to be incorrect.

[0058] It is understood that the hydraulic control device 100 for the fabric distributor provided in this embodiment includes a belt conveyor 110, a hydraulic drive unit, a valve body assembly, a position sensor assembly, and a controller 170. The hydraulic drive unit is connected to the belt conveyor 110 and drives the belt conveyor 110 to reciprocate. The valve body assembly controls the flow rate of hydraulic oil supplied from the oil tank 180 to the hydraulic drive unit. The position sensor assembly detects the switching signal of the valve body assembly. The controller 170 is electrically connected to the position sensor assembly and the hydraulic drive unit. The controller 170 can receive the switching signal sent by the position sensor assembly and, if the switching signal is correct, controls the hydraulic drive unit to start; if the switching signal is incorrect, it controls the hydraulic drive unit to stop. This configuration, by determining whether the valve body assembly is switched to a preset position, determines the switching state of the valve body assembly, avoiding incorrect valve assembly position or human error during operation that could cause abnormal operation of the hydraulic drive unit and damage, thus ensuring safety and stability in use.

[0059] In some examples, such as Figure 1 As shown, the hydraulic drive unit includes: a hydraulic cylinder assembly, which includes a first hydraulic cylinder 121 and a second hydraulic cylinder 122, both connected to the belt conveyor 110.

[0060] It is understood that the hydraulic drive unit may be equipped with a hydraulic cylinder assembly, a first oil supply assembly, and a second oil supply assembly. The hydraulic cylinder assembly includes a first hydraulic cylinder 121 and a second hydraulic cylinder 122. Specifically, both the first hydraulic cylinder 121 and the second hydraulic cylinder 122 are connected to the belt conveyor 110. The first hydraulic cylinder 121 drives the belt conveyor 110 to move in a first direction, and the second hydraulic cylinder 122 drives the belt conveyor 110 to move in a second direction, with the first and second directions being opposite, thereby driving the belt conveyor 110 to reciprocate. The first oil supply assembly is connected to the oil tank 180 and serves as the primary oil supply assembly, supplying oil to either the first hydraulic cylinder 121 or the second hydraulic cylinder 122. The second oil supply assembly serves as a backup oil supply assembly, supplying oil to either the first hydraulic cylinder 121 or the second hydraulic cylinder 122 when the first oil supply assembly is not in use. The controller 170 is electrically connected to the first oil supply component and the second oil supply component respectively. When the first oil supply component is used, the controller 170 can control the start and stop status of the first oil supply component; when the second oil supply component is used, the controller 170 can control the start and stop status of the second oil supply component.

[0061] It should be noted that the valve body assembly and the position sensor assembly are distributed on the first oil supply assembly and the second oil supply assembly. The valve body assembly controls the hydraulic oil flow of the first oil supply assembly and the second oil supply assembly, and the position sensor detects whether the opening and closing position of the valve body assembly is correct.

[0063] Understandably, the hydraulic control device 100 for the material distributor is also equipped with a flow-combining valve assembly 160. Specifically, the flow-combining valve assembly 160 is located between the hydraulic drive unit and the hydraulic cylinder assembly. By setting up the flow-combining valve assembly 160, the hydraulic oil can be ensured to flow in the correct direction, thereby improving stability.

[0064] In some examples, such as Figure 1 As shown, the first oil supply assembly includes: a first hydraulic pump 123 connected to the oil tank 180, used to pump hydraulic oil from the oil tank 180 to the first hydraulic cylinder 121 or the second hydraulic cylinder 122; and a first drive motor 124 connected to the first hydraulic pump 123. The first hydraulic pump 123 is provided with a first delivery port 1231 and a second delivery port 1232. The first delivery port 1231 is connected to the first hydraulic cylinder 121 through the first channel 161 of the manifold valve assembly 160; and the second delivery port 1232 is connected to the second hydraulic cylinder 122 through the second channel 162 of the manifold valve assembly 160.

[0065] It is understood that the first oil supply assembly is equipped with a first hydraulic pump 123 and a first drive motor 124. The first hydraulic pump 123 is connected to the oil tank 180 to pump hydraulic oil from the oil tank 180 to the first hydraulic cylinder 121 or the second hydraulic cylinder 122, and the first drive motor 124 provides power to the first hydraulic pump 123. Furthermore, the first hydraulic pump 123 is provided with a first delivery port 1231 and a second delivery port 1232. When using the first oil supply assembly, the first hydraulic pump 123 pumps the hydraulic oil in the oil tank 180 to the first hydraulic cylinder 121 through the first channel 161 of the manifold valve group 160, while the second hydraulic cylinder 122 discharges oil, and the hydraulic oil in the second hydraulic cylinder 122 is sent back to the first hydraulic pump 123 through the second channel 162 of the manifold valve group 160, so that the belt conveyor moves in the first direction. Subsequently, the first hydraulic cylinder 121 unloads oil, and the hydraulic oil in the first hydraulic cylinder 121 is sent back to the first hydraulic pump 123 through the first channel 161 of the manifold valve group 160. The first hydraulic pump 123 pumps the hydraulic oil to the second hydraulic cylinder 122 through the second channel 162 of the manifold valve group 160, so that the belt conveyor 110 moves in the second direction, thereby causing the belt conveyor 110 to reciprocate.

[0066] In some examples, such as Figure 1 As shown, the second oil supply assembly includes: a second hydraulic pump 125 connected to the oil tank 180, used to pump hydraulic oil from the oil tank 180 to the first hydraulic cylinder 121 or the second hydraulic cylinder 122; and a second drive motor 126 connected to the second hydraulic pump 125. The second hydraulic pump 125 is provided with a third delivery port 1251 and a fourth delivery port 1252. The third delivery port 1251 is connected to the first hydraulic cylinder 121 through the first channel 161; and the fourth delivery port 1252 is connected to the second hydraulic cylinder 122 through the second channel 162.

[0067] It is understood that the second oil supply assembly is equipped with a second hydraulic pump 125 and a second drive motor 126. The second hydraulic pump 125 is connected to the oil tank 180 to pump hydraulic oil from the oil tank 180 to the first hydraulic cylinder 121 or the second hydraulic cylinder 122, and the second drive motor 126 provides power to the second hydraulic pump 125. Furthermore, the second hydraulic pump 125 is provided with a third delivery port 1251 and a fourth delivery port 1252. When using the second oil supply assembly, the second hydraulic pump 125 pumps the hydraulic oil in the oil tank 180 to the first hydraulic cylinder 121 through the first channel 161 of the manifold valve group 160. At the same time, the second hydraulic cylinder 122 discharges oil, and the hydraulic oil in the second hydraulic cylinder 122 is sent back to the second hydraulic pump 125 through the second channel 162 of the manifold valve group 160, so that the belt conveyor moves in the first direction. Subsequently, the first hydraulic cylinder 121 discharges oil, and the hydraulic oil in the first hydraulic cylinder 121 is sent back to the second hydraulic pump 125 through the first channel 161 of the manifold valve group 160. The second hydraulic pump 125 pumps the hydraulic oil to the second hydraulic cylinder 122 through the second channel 162 of the manifold valve group 160, so that the belt conveyor 110 moves in the second direction, thereby causing the belt conveyor 110 to reciprocate.

[0068] In some examples, such as Figure 1 As shown, the valve body assembly includes: a first valve body 131 disposed between the oil tank 180 and the first hydraulic pump 123; a second valve body 132 disposed between the first delivery port 1231 and the first channel 161; and a third valve body 133 disposed between the second delivery port 1232 and the second channel 162.

[0069] Understandably, the valve body assembly includes a first valve body 131, a second valve body 132, and a third valve body 133. The first valve body 131 is located between the oil tank 180 and the first hydraulic pump 123; when the first valve body 131 is in the open position, the oil tank 180 is connected to the first hydraulic pump 123. The second valve body 132 is located between the first delivery port 1231 and the first channel 161; when the second valve body 132 is in the open position, the first delivery port 1231 is connected to the first channel 161. The third valve body 133 is located between the second delivery port 1232 and the second channel 162; when the third valve body 133 is in the open position, the second delivery port 1232 is connected to the second channel 162. With this configuration, when the first oil supply component is used, the first valve body 131, the second valve body 132, and the third valve body 133 are all in the open state. Then the first hydraulic pump 123 works normally, supplying hydraulic oil to the first hydraulic cylinder 121 or the second hydraulic cylinder 122 to drive the belt conveyor 110 to reciprocate.

[0070] In some examples, such as Figure 1As shown, the valve body assembly further includes: a fourth valve body 134, disposed between the oil tank 180 and the second hydraulic pump 125; a fifth valve body 135, disposed between the third delivery port 1251 and the first channel 161; and a sixth valve body 136, disposed between the fourth delivery port and the second channel 162.

[0071] Understandably, the valve body assembly also includes a fourth valve body 134, a fifth valve body 135, and a sixth valve body 136. The fourth valve body 134 is located between the oil tank 180 and the second hydraulic pump 125. When the fourth valve body 134 is in the open position, the oil tank 180 is connected to the second hydraulic pump 125. The fifth valve body 135 is located between the third delivery port 1251 and the first channel 161. When the fifth valve body 135 is in the open position, the third delivery port 1251 is connected to the first channel 161. The sixth valve body 136 is located between the fourth delivery port and the second channel 162. When the sixth valve body 136 is in the open position, the fourth delivery port is connected to the second channel 162. With this configuration, when the second oil supply assembly is used, the fourth valve body 134, the fifth valve body 135, and the sixth valve body 136 are all in the open state. Therefore, the second hydraulic pump 125 operates normally, supplying hydraulic oil to either the first hydraulic cylinder 121 or the second hydraulic cylinder 122 to drive the belt conveyor 110 in reciprocating motion.

[0072] It should be noted that the first valve body 131, the second valve body 132 and the third valve body 133 can be normally open valve bodies, and the fourth valve body 134, the fifth valve body 135 and the sixth valve body 136 can be normally closed valve bodies.

[0073] In some examples, such as Figure 1 As shown, the position sensor assembly includes: a first sensor 141, disposed in the open position of the first valve body 131, for detecting whether the first valve body 131 is fully open; a second sensor 142, disposed in the closed position of the first valve body 131, for detecting whether the second valve body 132 is fully closed; a third sensor 143, disposed in the open position of the second valve body 132, for detecting whether the second valve body 132 is fully open; a fourth sensor 144, disposed in the closed position of the second valve body 132, for detecting whether the second valve body 132 is fully closed; a fifth sensor 145, disposed in the open position of the third valve body 133, for detecting whether the third valve body 133 is fully open; and a sixth sensor 146, disposed in the closed position of the third valve body 133, for detecting whether the third valve body 133 is fully closed.

[0074] Understandably, the position sensor assembly includes a first sensor 141, a second sensor 142, a third sensor 143, a fourth sensor 144, a fifth sensor 145, and a sixth sensor 146. Specifically, the first sensor 141 is positioned in the open position of the first valve body 131 to detect whether the first valve body 131 is fully open; the second sensor 142 is positioned in the closed position of the first valve body 131 to detect whether the first valve body 131 is fully closed; the third sensor 143 is positioned in the open position of the second valve body 132 to detect whether the second valve body 132 is fully open; the fourth sensor 144 is positioned in the closed position of the second valve body 132 to detect whether the second valve body 132 is fully closed; the fifth sensor 145 is positioned in the open position of the third valve body 133 to detect whether the third valve body 133 is fully open; and the sixth sensor 146 is positioned in the closed position of the third valve body 133 to detect whether the third valve body 133 is fully closed. The first sensor 141, the second sensor 142, the third sensor 143, the fourth sensor 144, the fifth sensor 145, and the sixth sensor 146 are all electrically connected to the controller 170. With this configuration, when the first oil supply assembly is in use and all valves of the second oil supply assembly are closed, if the first sensor 141 detects that the first valve 131 is open, the third sensor 143 detects that the second valve 132 is open, and the fifth sensor 145 detects that the third valve 133 is open, it indicates that all valves of the first oil supply assembly are in the correct position, and the controller 170 controls the first drive motor 124 and the first hydraulic pump 123 to operate normally. If at least one of the first sensor 141, the third sensor 143, and the fifth sensor 145 fails to detect that the corresponding valve body is in the open state; and / or the second sensor 142 detects that the first valve body 131 is in the closed position and / or the fourth sensor 144 detects that the second valve body 132 is in the closed position; and / or the sixth sensor 146 detects that the third valve body 133 is in the closed position, it indicates that there is a valve body in the first oil supply assembly in an incorrect position. The controller 170 controls the first drive motor 124 and the first hydraulic pump 123 to shut down to prevent the hydraulic oil from being unable to be delivered to the first hydraulic pump 123 when the first valve body 131 is closed, which would cause the first hydraulic pump 123 to run without oil and be damaged; or the second valve body 132 is closed, which would cause the hydraulic oil to be unable to be delivered to the first hydraulic cylinder 121; or the third valve body 133 is closed, which would cause the hydraulic oil to be unable to be delivered to the second hydraulic cylinder 122, which would cause the belt conveyor 110 to be unable to perform normal reciprocating motion.

[0075] In some examples, such as Figure 1As shown, the valve body assembly further includes: the position sensor assembly further includes: a seventh sensor 151, disposed in the open position of the fourth valve body 134, for detecting whether the fourth valve body 134 is fully open; an eighth sensor 152, disposed in the closed position of the fourth valve body 134, for detecting whether the fourth valve body 134 is fully closed; a ninth sensor 153, disposed in the open position of the fifth valve body 135, for detecting whether the fifth valve body 135 is fully open; a tenth sensor 154, disposed in the closed position of the fifth valve body 135, for detecting whether the fifth valve body 135 is fully closed; an eleventh sensor 155, disposed in the open position of the sixth valve body 136, for detecting whether the sixth valve body 136 is fully open; and a twelfth sensor 156, disposed in the closed position of the sixth valve body 136, for detecting whether the sixth valve body 136 is fully closed.

[0076] Understandably, the position sensor assembly includes a seventh sensor 151, an eighth sensor 152, a ninth sensor 153, a tenth sensor 154, an eleventh sensor 155, and a twelfth sensor 156. Specifically, the seventh sensor 151 is positioned in the open position of the fourth valve body 134 to detect whether the fourth valve body 134 is fully open; the eighth sensor 152 is positioned in the closed position of the fourth valve body 134 to detect whether the fourth valve body 134 is fully closed; the ninth sensor 153 is positioned in the open position of the fifth valve body 135 to detect whether the fifth valve body 135 is fully open; the tenth sensor 154 is positioned in the closed position of the fifth valve body 135 to detect whether the fifth valve body 135 is fully closed; the eleventh sensor 155 is positioned in the open position of the sixth valve body 136 to detect whether the sixth valve body 136 is fully open; and the twelfth sensor 156 is positioned in the closed position of the sixth valve body 136 to detect whether the sixth valve body 136 is fully closed. The seventh sensor 151, the eighth sensor 152, the ninth sensor 153, the tenth sensor 154, the eleventh sensor 155, and the twelfth sensor 156 are all electrically connected to the controller 170. With this configuration, when using the second oil supply assembly, if the seventh sensor 151 detects that the fourth valve body 134 is open, the ninth sensor 153 detects that the fifth valve body 135 is open, and the eleventh sensor 155 detects that the sixth valve body 136 is open, while the second sensor 142 detects that the first valve body 131 is closed, the fourth sensor 144 detects that the second valve body 132 is closed, and the sixth sensor 146 detects that the third valve body 133 is closed, it indicates that all valves of the second oil supply assembly are in the correct positions, and the controller 170 controls the second drive motor 126 and the second hydraulic pump 125 to operate normally. If at least one of the seventh sensor 151, the ninth sensor 153, and the eleventh sensor 155 fails to detect that the corresponding valve body is in the open state; and / or the eighth sensor 152 detects that the fourth valve body 134 is in the closed position and / or the tenth sensor 154 detects that the fifth valve body 135 is in the closed position; and / or the twelfth sensor 156 detects that the sixth valve body 136 is in the closed position, it indicates that there is a valve body in the second oil supply assembly in an incorrect position. The controller 170 controls the second drive motor 126 and the second hydraulic pump 125 to shut down to prevent hydraulic oil from being unable to be delivered to the second hydraulic pump 125 when the fourth valve body 134 is closed, which would cause the second hydraulic pump 125 to run without oil and be damaged; or the second valve body 132 is closed, which would cause hydraulic oil to be unable to be delivered to the first hydraulic cylinder 121; or the third valve body 133 is closed, which would cause hydraulic oil to be unable to be delivered to the second hydraulic cylinder 122, which would cause the belt conveyor 110 to be unable to perform normal reciprocating motion.If at least one of the first to third valve bodies 133 is in the open state, it will cause a conflict in the oil supply of the first hydraulic pump 123 and the second hydraulic pump 125, causing the first hydraulic pump 123 or the second hydraulic pump 125 to be damaged by oil pressure when it is stopped. This will achieve automatic shutdown for protection and ensure that the hydraulic control device 100 of the material distributor can operate safely and reliably, thus avoiding equipment damage.

[0077] It should be noted that when using the first oil supply component, the first to third valves are in the open state, the fifth and sixth valves are in the closed state, and the fourth valve can be either open or closed.

[0078] In some examples, such as Figure 1 As shown, the above-mentioned hydraulic control device 100 for the fabric distributor also includes: a plurality of indicator lights, which are respectively installed at the first to twelfth sensors 156. When the first to twelfth sensors 156 detect the corresponding opening signal correctly, the indicator lights are lit.

[0079] Understandably, the hydraulic control device 100 for the material distributor is also equipped with multiple indicator lights, located at the first to twelfth sensors 156 respectively. When the first to twelfth sensors 156 detect the corresponding switch signal correctly, the indicator lights illuminate. Specifically, when using the first oil supply assembly, if the indicator lights at the first sensor 141, the third sensor 143, and the fifth sensor 145 are illuminated, and the indicator light at the seventh sensor 151 is either on or off (meaning the fourth valve 134 can be open or closed), and simultaneously the indicator light at the tenth sensor 154 is illuminated (meaning the fifth valve 135 is closed), and the indicator light at the twelfth sensor 156 is illuminated (meaning the sixth valve 136 is closed), it indicates that all valves are in the correct open / closed position, and the controller 170 controls the first drive motor 124 and the first hydraulic pump 123 to start. When the second oil supply assembly is in use, the indicator lights at the seventh sensor 151, the ninth sensor 153, and the eleventh sensor 155 are lit, and the indicator light at the second sensor 142 is either lit or off, indicating that the first valve body 131 can be opened or closed. At the same time, the indicator light at the fourth sensor 144 is lit, indicating that the second valve body 132 is closed. When the indicator light at the sixth sensor 146 is lit, indicating that the third valve body 133 is closed, it indicates that the opening and closing positions of all valves are correct, and the controller 170 controls the second drive motor 126 and the second hydraulic pump 125 to start.
