Description

Technical Field

[0001] The utility model relates to the technical field of copper foil production, and more particularly to an electric lifting device for maintaining a stable suction height of an additive pump body. Background Art

[0002] In copper foil production, additives are pumped into the raw foil system via a peristaltic pump. Currently, the additives are stored in containers, with the peristaltic pump mounted above the container. As the additives are pumped into the raw foil system, the liquid level in the additive storage container drops. This change in the peristaltic pump's suction height (the difference between the peristaltic pump's installation position and the liquid level in the additive storage container) causes variations in the amount of additives drawn in by the peristaltic pump. This unstable additive level can affect copper foil production. Utility Model Content

[0003] In view of the problems existing in the prior art, the purpose of the utility model is to provide an electric lifting device that can maintain the stable suction height of an additive peristaltic pump.

[0006] Preferably, the lifting assembly includes a base and a carrying plate for carrying the container and located above the base, a vertically guided telescopic connection structure is installed between the base and the carrying plate, and also includes a lifting drive for driving the telescopic connection structure to lift and lower the carrying plate.

[0007] Preferably, the pump body is mounted on a cantilever and thus suspended in the air, and is located inside or directly above the container.

[0008] Preferably, a limiting block for positioning the bottom of the container is installed on the top of the carrying plate.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] refer to Figure 1-3An electric lifting device for maintaining a stable suction height of an additive pump body comprises: a container 1 for storing additives and a pump body 2 for extracting the additive from the container 1. The pump body 2 is equipped with an inlet pipe 21 extending into the container 1 and an outlet pipe 22 connected to the outside. The device also includes a lifting assembly 3 for lifting the container 1 or pump body 2, and a sensor 4 installed in the container 1 for real-time liquid level detection. The sensor 4 is connected to a controller, which is connected to the lifting assembly 3 and thereby drives the container 1 or pump body 2 to lift and lower, thereby controlling the distance between the pump body 2 and the liquid level in the container 1. It is understood that the container 1 is the component for storing additives, such as, but not limited to, a tank or barrel. The pump body 2 is the driving component for extracting additives, such as, but not limited to, a centrifugal pump or a peristaltic pump. The lifting assembly 3 is the component for lifting the container 1 or pump body 2, such as, but not limited to, a threaded screw lifting structure, an electric push rod, a cylinder, or other lifting structure with a guide rail. The sensor 4 is a component used for detecting the liquid level of the additive, and may be, for example, an ultrasonic sensor 4, a pressure sensor 4, a capacitive liquid level sensor 4, etc., but is not limited thereto. The controller can read the liquid level information of the sensor 4, perform data analysis and processing to determine the current liquid level, and decide whether it is necessary to adjust the suction height of the pump body 2, and formulate a corresponding control algorithm based on the change in the liquid level, and finally control the operation of the lifting component 3, which may be, for example, a microcontroller or a PLC. In this way, during the process of the pump body 2 extracting the additive from the container 1, the additive liquid level will continue to drop, and the liquid level will be detected in real time by the sensor 4. The sensor 4 transmits the signal to the controller, which reads the liquid level information in real time and performs data processing. Finally, the lifting component 3 is controlled to operate to control the height of the container 1 or the pump body 2, thereby achieving consistency in the suction height of the pump body 2 to ensure the stability of the additive suction amount.

[0021] In some embodiments, reference Figure 1 and Figure 3The lifting assembly 3 includes a base 31 and a supporting plate 32 for supporting the container 1 and located above the base 31. A vertically guided telescopic connection structure 33 is installed between the base 31 and the supporting plate 32. It also includes a lifting driver 34 that drives the telescopic connection structure 33 and thereby lifts and lowers the supporting plate 32. It is understandable that the telescopic connection structure 33 is a component that connects the base 31 and the supporting plate 32 and guides them vertically. For example, it can be a scissor-type structure or a telescopic rod structure, but is not limited to this. The lifting driver 34 can be a cylinder, a hydraulic cylinder, a motor and a gear for chain lifting, a screw 36 for lifting, etc., but is not limited to this. Furthermore, the pump body 2 is mounted on the cantilever 5 and is thus suspended in the air, and is located inside or directly above the container 1. It is understandable that the cantilever 5 is a component that suspends and fixes the pump body 2 in the air. For example, it can be a structure such as a bending arm fixed to the ground or a rope, a connecting rod fixed to the ceiling, but is not limited to this. Here, the pump body 2 is suspended and fixed, so the height position of the pump body 2 can be locked, and the lifting drive 34 drives the telescopic connection structure 33 to drive the supporting plate 32 and then drives the container 1 to move up and down, so as to achieve a constant distance between the liquid level and the pump body 2.

[0022] In some embodiments, a stopper 6 is mounted on top of the support plate 32 to position the bottom of the container 1. The stopper 6 can be an annular structure that matches the shape of the bottom of the container 1, or it can be spaced apart. Thus, the stopper 6 can position the container 1 and prevent it from shifting.

[0023] In some embodiments, reference Figure 2 and Figure 3 The lifting assembly 3 includes a fixed frame 35 installed above the container 1, and a screw 36 and a guide rod 37 are installed on the fixed frame 35, which are vertically arranged and extend into the container 1. A transmission block 38 is threadedly sleeved on the screw 36, and the transmission block 38 is guided on the guide rod 37. A control motor 39 for driving the screw 36 to rotate is also installed on the fixed frame 35, and the pump body 2 is installed on the transmission block 38. Here, the fixed frame 35 can be fixedly installed on the container 1 or fixedly installed on the ground. Specifically, the fixed frame 35 includes a bending plate 351 installed on the top of the container 1 and a bottom plate 352 corresponding to the bending plate 351 and installed at the bottom of the container 1. The screw 36 and the guide rod 37 are installed between the bottom plate 352 and the bending plate 351. The control motor 39 needs to adopt a stepper motor or a servo motor. In this way, by controlling the motor 39 to drive the screw 36 to rotate forward and reverse, the transmission block 38 is driven to move up and down, and the pump body 2 is driven to move up and down, so as to achieve the consistency of the distance between the pump body 2 and the liquid surface.

[0024] In some embodiments, the sensor 4 is a pressure sensor 4 mounted on the bottom of the container 1. The pressure sensor 4 can detect the pressure of the additive and convert it into liquid level data through the controller. The pressure sensor 4 is more sensitive, which helps improve the control accuracy of the suction height of the pump body 2.

[0025] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed in the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
