Description

Technical Field

[0001] The present invention relates to the technical field of belt conveying, and more particularly to a gravity-stabilized lifting, positioning and conveying device for a care liquid pump head. Background Art

[0002] The center-of-gravity stabilized lifting and positioning device for the care solution pump head has multiple uses in the delivery of care solutions or other liquids, primarily in lifting and conveying liquids. The pump head design allows the device to stably extract care solutions from storage containers and deliver them to a designated location. This lifting and conveying function is particularly useful when liquids need to be moved from one height to another, such as when delivering care solutions to filling or packaging equipment on a production line.

[0003] Patent publication number CN105253545A discloses a ratchet-type, non-retractable lifting, positioning, and conveying device. This invention reduces worker labor intensity and workpiece damage, offering excellent applicability. It utilizes pneumatic and hydraulic drive, ensuring uniform and stable force on the copper anode plate and safe and reliable operation. The entire mechanism is easy to disassemble and repair, with common components, eliminating the need for specialized maintenance and resulting in low costs. This reduces labor costs and improves the company's economic benefits. However, this patent suffers from the following drawbacks.

[0004] During the lifting and conveying process of the care liquid pump head, it is difficult to accurately position the two sides of the care liquid pump head during the conveying process, which will cause the care liquid pump head to deviate to the sides during the conveying process. At the same time, the top of the care liquid pump head is difficult to accurately position and convey, and the care liquid pump head is prone to tilt and vertical deviation. The conveying center of gravity of the care liquid pump head is easily offset, and the delivery stability of the care liquid pump head is poor. Therefore, a care liquid pump head center of gravity stable lifting, positioning and conveying device is needed. Summary of the Invention

The inner wall of the conveyor belt is provided with two belt rollers with transmission connection, and the belt rollers are rotationally connected to the inclined bracket. A transmission motor is fixedly installed on one end of one of the belt rollers; the transmission motor is fixedly connected to the inclined bracket.

[0008] When using this technology, the controller activates the reduction motor, which drives the bidirectional screw to rotate. The bidirectional screw drives the two threaded sleeves toward each other under the action of the thread transmission force. The connecting bar causes the positioning side bar to move rightward. The positioning side bar moves rightward along the upper inclined surface of the positioning sleeve, while the other positioning side bar moves leftward.

[0009] Preferably, the top positioning precision conveying assembly includes a sliding sleeve frame fixedly arranged on one side of the inclined bracket; the inner wall of the sliding sleeve frame is rotatably connected to a connecting screw, and one end of the sliding sleeve frame is fixedly installed with a driving motor, and the driving motor is used to drive the connecting screw to rotate, and the outer wall of the connecting screw is threadedly connected to a sleeve recess, and the sleeve recess is slidably connected to the sliding sleeve frame.

[0010] A push rod is fixedly mounted on one side of the inner wall of the sleeve recess, and a sleeve rod is rotatably connected to the outer wall of the push rod. A linkage shaft is rotatably connected to the inner wall of the sleeve rod and away from the push rod, and a hinge block is fixedly mounted on one end of the linkage shaft, and the hinge block is fixedly connected to the top positioning bar.

At the same time, the linkage shaft drives the hinge block to move downward, and the top positioning bar drives the guide rod to move downward. The vertical distance sensor realizes distance sensing of the top positioning bar. When the distance value sensed by the vertical distance sensor is the same as the distance value set by the controller, the driving motor is turned off by the controller.

When the distance value sensed by the lateral distance sensor matches the distance set by the controller, the controller shuts off the reduction motor.

[0014] Technical effects and advantages of the present invention:

[0015] 1. The present invention positions and conveys components through transverse intervals. The controller starts the reduction motor, and the reduction motor drives the bidirectional screw to rotate. The bidirectional screw drives the two threaded sleeves to approach each other under the action of the thread transmission force. The threaded sleeve drives the connecting bar to move right. The connecting bar causes the positioning side bar to move right. The positioning side bar moves right along the upper inclined surface of the positioning sleeve, while the other positioning side bar moves left. The two positioning side bars can accurately position and convey the two sides of the care liquid pump head according to the specified distance, thereby avoiding the deviation of the delivery center of gravity of the care liquid pump head and greatly improving the delivery stability of the care liquid pump head.

[0016] 2. The present invention adopts a top positioning and precise conveying component. The driving motor drives the connecting screw to rotate, and the connecting screw drives the sleeve concave block to move right under the action of the thread transmission force. The push rod drives the top of the sleeve rod to move right, and the linkage shaft drives the hinge block to move downward. The hinge block drives the top positioning bar to move downward and squeeze. When the distance value sensed by the vertical distance sensor is the same as the distance value set by the controller, the driving motor is turned off by the controller, and the top of the care liquid pump head can be accurately positioned and conveyed according to the specified distance, avoiding the deviation of the delivery center of gravity of the care liquid pump head and greatly improving the stability of the care liquid pump head delivery.

[0017] 3. The present invention uses a positioning and guiding mechanism. When the positioning side bar moves to the right, it will drive the sliding sleeve to move to the right, and the other positioning side bar will drive the other sliding sleeve to move to the left. The sliding sleeve will be guided to move to the right along the inner wall of the guide frame. In this way, both sliding sleeves can realize guided sliding operation along the inner wall of the guide frame. When the distance value sensed by the lateral distance sensor is the same as the distance set by the controller, the reduction motor is turned off by the controller, thereby increasing the stability of the guide sleeve, avoiding the deviation of the delivery center of gravity of the care liquid pump head, and greatly improving the delivery stability of the care liquid pump head.

[0018] The above-mentioned multiple functions interact with each other. First, the two positioning side strips can accurately position and transport the two sides of the care liquid pump head according to the specified distance. Secondly, the hinged block drives the top positioning strip to move downward and squeeze, and the top positioning strip accurately positions and transports the top of the care liquid pump head. Then, when the distance value sensed by the lateral distance sensor is the same as the distance set by the controller, the reduction motor is turned off by the controller to increase the stability of the guide sleeve. In summary, the two sides of the care liquid pump head can be accurately positioned and transported according to the specified distance, and the top of the care liquid pump head can be accurately positioned and transported according to the specified distance, avoiding the deviation of the delivery center of gravity of the care liquid pump head and greatly improving the stability of the care liquid pump head delivery.

[0038] The working principle of the gravity-stabilized lifting, positioning and conveying device for the care liquid pump head of the present invention is as follows:

[0039] Step 1: During horizontal spacing and positioning transport, the two support bases 12 are supported by the support concave plate 13. The support bases 12 support the tilting bracket 1, and the tilting bracket 1 supports the sleeve frame 2, increasing the stability of the sleeve frame 2 during use. Simultaneously, the controller 14 activates the reduction motor 4, which drives the bidirectional screw 3 to rotate. The bidirectional screw 3 drives the two threaded sleeves 5 toward each other under the action of the thread transmission force. The threaded sleeve 5 moves right along the inner wall of the sleeve frame 2, and the threaded sleeve 5 drives the connecting bar 6 to move right. The connecting bar 6 causes the positioning side bar 7 to move right. The positioning side bar 7 moves right along the upper inclined surface of the positioning sleeve 10, while the other positioning side bar 7 moves left.

[0040] During step 2, top positioning and precise delivery, controller 14 simultaneously activates drive motor 19, which drives connecting screw 18 to rotate. Connecting screw 18 drives socket block 20 to move rightward under the action of thread transmission force. Socket block 20 drives push rod 21 to move rightward, push rod 21 drives the top end of socket rod 22 to move rightward, and socket rod 22 drives linkage shaft 23 downward. Simultaneously, linkage shaft 23 drives hinge block 24 downward, which drives top positioning bar 25 downward and squeezes it. Top positioning bar 25 drives guide rod 26 downward, which guides it downward along the inner wall of socket slide 27. Simultaneously, vertical distance sensor 28 senses the distance to top positioning bar 25. When the distance value sensed by vertical distance sensor 28 matches the distance value set by controller 14, controller 14 turns off drive motor 19.

[0041] Step 3: During positioning and guiding, when the positioning side bar 7 moves rightward, it drives the sliding sleeve 30 to move rightward, while the other positioning side bar 7 drives the other sliding sleeve 30 to move leftward. The sliding sleeve 30 then drives the lateral distance sensor 31 to move rightward. The sliding sleeve 30 then slides along the outer wall of the slide bar 32. Simultaneously, the sliding sleeve 30 moves rightward along the inner wall of the guide frame 29. In this way, both sliding sleeves 30 can achieve guided sliding along the inner wall of the guide frame 29. The lateral distance sensor 31 senses the distance of the sensing block 33. When the distance value sensed by the lateral distance sensor 31 matches the distance set by the controller 14, the controller 14 turns off the reduction motor 4. Simultaneously, the top positioning bar 25 drives the sliding shaft 35 to slide tiltedly. The sliding shaft 35 then slides down the inner wall of the guide sleeve 34. The guide frame 29 provides stable support for the guide sleeve 34, increasing its operational stability.

[0042] Step 4. During lifting and conveying, insert the care liquid pump head into the pump head positioning hole 11 inside the positioning sleeve 10, and realize the positioning operation of the care liquid pump head through the pump head positioning hole 11. At the same time, the care liquid pump head can realize positioning and conveying on both sides through the two positioning side strips 7, and the tilting bracket 1 supports the transmission motor 16, and the controller 14 starts the transmission motor 16. The transmission motor 16 drives the belt roller 15 to transmit, and the belt roller 15 drives the conveying belt 8 to realize the transmission and conveying operation. In this way, the conveying belt 8 drives the two limiting strips 9 to transmit, and the limiting strips 9 drive the positioning sleeve 10 to tilt upward, and the positioning sleeve 10 drives the care liquid pump head to tilt upward. In this way, the care liquid pump head can be accurately positioned and conveyed along the two positioning side strips 7, while the top of the care liquid pump head can be guided and tilted upward along the lower clear surface of the top positioning strip 25, and the lifting and conveying of the care liquid pump head is more stable.
