Description

Technical Field

[0001] This invention relates to the field of production line tank liquid level control technology, specifically to a PVC glove production line tank liquid level monitoring device. Background Technology

[0002] The cable float level gauge is a device integrally molded from plastic through injection molding, consisting of a cable, a limit switch, and a float switch. Patent document (authorization announcement number CN 217117612 U) discloses a PVC glove production line tank material level controller. In use, the controller first achieves level control through a sliding frame at the bottom of the controller body and a sliding block installed inside it. A stainless steel float is connected to one side of the sliding block. When the delivery pump injects material into the tank, the stainless steel float moves the sliding block according to the change in liquid level. When the stainless steel float floats to the surface, the electrical control system stops the delivery pump from conveying material into the tank. Conversely, when the liquid level is low and the stainless steel float sinks to the bottom of the tank, the delivery pump is activated to convey material into the tank.

[0003] The aforementioned level controller uses a cable float level gauge. During installation, the cable float level gauge has requirements regarding the height of the tank. The float needs to float, and the bending coefficient of the connecting cable must be considered. Otherwise, when used in a low-height tank, the connecting cable is prone to tangling, leading to level switch malfunction. Simultaneously, the sliding block in the level controller can move vertically on the sliding frame. As the sliding block moves upward, the connecting cable on the sliding block may become entangled and float in the water. This cable may also become entangled and float above the float, potentially obstructing the float's as it rises. This can prevent the float from rising accurately according to the liquid level, or the obstruction may cause the sliding block to jam, resulting in level switch malfunction, even if the liquid level in the tank exceeds the actual float switch height. Summary of the Invention

[0004] The purpose of this invention is to provide a PVC glove production line tank liquid level monitoring device.

[0005] The technical problem solved by this invention is:

[0006] (1) When using the cable float level gauge, there are requirements for the height of the tank when it is installed. The float needs to float. The bending coefficient of the connecting cable needs to be considered. Otherwise, when used in a low-height tank, the connecting cable may get tangled, causing the level switch to malfunction.

[0007] (2) When the sliding block moves upward, the connecting cable on the sliding block will be wrapped and float in the water. The connecting cable may be wrapped and float above the float. When the float drives the sliding block to rise, the float is easily blocked by the connecting cable above it, and cannot rise accurately according to the liquid level. Or the float is blocked and the sliding block is stuck, causing the liquid level switch to malfunction. Even if the liquid level in the tank exceeds the actual float height, the float cannot float.

[0008] The objective of this invention can be achieved through the following technical solutions:

A soft pad is fixedly installed on this end, and the soft pad is pressed against the cable.

[0014] As a further aspect of the present invention: the clamping member includes an upper clamping block and a lower clamping block, the upper clamping block and the lower clamping block are arranged vertically, and an arc-shaped groove is provided on the side of the upper clamping block and the lower clamping block that is close to each other, and the size of the arc-shaped groove is adapted to the size of the cable. The cable is located between the upper clamping block and the lower clamping block, and the upper clamping block and the lower clamping block are fixed together by a plurality of second fastening bolts; the bottom of the moving rod is fixedly connected to the top of the upper clamping block.

[0015] As a further aspect of the present invention: a second sliding groove is provided on the inner side wall of the trough box. The second sliding groove is horizontally arranged and is connected to the first sliding groove. The cable is located in the first sliding groove and the second sliding groove. The upper clamping block and the lower clamping block are both horizontally slidably installed on the second sliding groove.

[0016] As a further embodiment of the present invention: the inner wall of the trough box is provided with a rectangular through hole, the rectangular through hole is connected to the second slide groove, the moving rod is inserted into the rectangular through hole, and the cable is located in the rectangular through hole, the second slide groove and the first slide groove.

[0017] As a further embodiment of the present invention: the cable storage assembly further includes a fixing ring, a connecting rod and a threaded screw, a mounting block is fixedly provided on the top of the trough box, the threaded screw is arranged along the length direction of the second sliding groove and is rotatably mounted on the mounting block, the moving rod extends upward through a rectangular through hole, the fixing ring is fixedly sleeved on the top of the moving rod, one end of the connecting rod is fixedly mounted on the fixing ring, and the other end is threadedly sleeved on the threaded screw.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] 1. With the help of the external electrical control system, the liquid level control component can automatically feed materials into the tank. Specifically, when the float reaches the liquid surface, the external electrical control system controls the pump to stop conveying materials into the tank. When the liquid level in the tank is low, the float will sink to the bottom of the tank, at which point the electrical control system will start the pump to convey materials into the tank.

[0022] 2. With the cable storage component in place, as the pump body delivers material into the tank, the float rises with the increase in the liquid level. At this time, the cable will be floating. To prevent the cable from getting tangled and floating above the float, thus obstructing its normal up-and-down movement, the electrical control system will start the drive motor. The drive motor will drive the screw to rotate. As the float rises, the rotation of the screw will cause the moving rod to move from right to left. During this process, the moving rod can pull the cable to store it, preventing the cable from getting tangled and floating above the float, thus ensuring the normal operation of the float.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] like Figures 1-8As shown, a PVC glove production line material level monitoring device includes a material tank 1, which has an inlet and an outlet. A pump body 20 is installed on the material tank 1, and an extraction pipe (not shown in the figure) and an inlet pipe 21 are installed on the pump body 20. The inlet pipe 21 is fixedly inserted into the inlet of the material tank 1. The pump body 20 supplies external materials into the material tank 1 through the extraction pipe and the inlet pipe 21. An outlet pipe 22 is fixedly installed at the outlet of the material tank 1, and a valve is installed on the outlet pipe 22. The outlet pipe 22 is used to discharge the material in the material tank 1.

[0035] like Figures 1-3 As shown, a liquid level control assembly and a cable storage assembly are also provided on the material tank 1. The liquid level control assembly includes a liquid level controller 2, a cable 3, and a float 4. The liquid level controller 2 is installed on the material tank 1, and the float 4 is placed inside the material tank 1. The two ends of the cable 3 are fixedly connected to the liquid level controller 2 and the float 4, respectively. When the float 4 floats to the liquid surface, the external electrical control system (not shown in the figure) controls the pump body 20 to stop conveying material into the material tank 1. When the liquid level in the material tank 1 is low, the float 4 will sink to the bottom of the material tank 1. At this time, the electrical control system will start the pump body 20 to convey material into the material tank 1. During the process of pump body 20 conveying materials into tank 1, float 4 will rise with the rise of material liquid level. At this time, cable 3 will be in a floating state. In order to prevent cable 3 from getting tangled and floating above float 4 and blocking float 4 from working normally up and down, the electrical control system will activate cable storage component. Cable storage component will store cable 3 during the rise of float 4, so that cable 3 will not get tangled and float above float 4, thus ensuring the normal operation of float 4.

[0036] Regarding the cable storage assembly described above, the cable storage assembly includes a moving rod 5 and a clamping member 6. The moving rod 5 is horizontally slidably installed on the inner side wall of the tank 1, and the clamping member 6 is fixedly installed on the bottom of the moving rod 5. The clamping member 6 is used to clamp and fix the cable 3. During the process of the float 4 rising, the electronic control system will control the moving rod 5 to move horizontally. The movement of the moving rod 5 will drive the clamping member 6 to move, and the clamping member 6 will drive the cable 3 to move, so that the cable 3 will not be tangled and float above the float 4, ensuring the normal operation of the float 4. To facilitate the movement of the cable 3, a first sliding groove 7 is provided on the inner wall of the tank 1. The first sliding groove 7 is arranged vertically, and a slider 8 is vertically slidably installed on the first sliding groove 7. The cable 3 is installed on the slider 8 and placed inside the first sliding groove 7. Specifically, circular through holes 9 are provided on the top and side of the slider 8, and the two circular through holes 9 are connected. The two ends of the cable 3 are installed on the slider 8 through the two circular through holes 9. That is, the up and down movement of the float 4 can drive the slider 8 to move up and down through the cable 3. The moving rod 5 can store the cable 3 above the slider 8, so that the cable 3 above the slider 8 will not be tangled and floating above the float 4 as the slider 8 rises with the float 4.

[0037] like Figures 4-6 As shown, in order to ensure the stability of the cable 3 installed on the slider 8, a first fastening bolt 10 is threaded on the slider 8, and one end of the first fastening bolt 10 is located in one of the circular through holes 9. A soft pad 11 is fixedly installed on this end, and the soft pad 11 is pressed against the cable 3.

[0038] like Figures 7-8 As shown, the clamping member 6 includes an upper clamping block 61 and a lower clamping block 62, which are arranged vertically. An arc-shaped groove 63 is provided on the side of the upper clamping block 61 and the lower clamping block 62 that is close to each other. The size of the arc-shaped groove 63 is adapted to the size of the cable 3. The two arc-shaped grooves 63 clamp and fix the cable 3. The upper clamping block 61 and the lower clamping block 62 are fixed together by multiple second fastening bolts 12. The bottom of the moving rod 5 is fixedly connected to the top of the upper clamping block 61. When the moving rod 5 moves horizontally, it can drive the upper clamping block 61 and the lower clamping block 62 to move the cable 3 horizontally, thus storing the cable 3. A second sliding groove 13 is provided on the inner wall of the material tank 1. The second sliding groove 13 is horizontally arranged and is connected to the first sliding groove 7. The cable 3 will be located in the first sliding groove 7 and the second sliding groove 13. The upper clamping block 61 and the lower clamping block 62 both slide horizontally on the second sliding groove 13. Figure 3As shown, during the ascent of the float 4, the upper clamping block 61 and the lower clamping block 62 will drive the cable 3 to move to the left. That is, the cable 3 will move upward in the first slide 7 and from right to left in the second slide 13. The second slide 13 will store the cable 3 on the left side of the clamping member 6. At the same time, in order to better store the cable 3 in the second slide 13, a receiving groove 19 is provided on the inner side wall of the tank 1. The receiving groove 19 is located below the second slide 13 and is connected to the second slide 13. When the cable 3 moves from right to left in the second slide 13, the cable 3 will move and be stored in the receiving groove 19. That is, the receiving groove 19 can better store the cable 3 in the second slide 13, ensuring that the cable 3 does not float above the float 4.

[0039] like Figure 3 As shown, in order to enable the moving rod 5 to move stably within the tank 1, a rectangular through hole 14 is provided on the inner wall of the tank 1. The rectangular through hole 14 is connected to the second slide 13. The moving rod 5 is inserted into the rectangular through hole 14. The liquid level controller 2 is located above the rectangular through hole 14. The cable 3 connected to it passes through the rectangular through hole 14, the second slide 13 and the first slide 7 from top to bottom until the other end of the cable 3 passes through the circular through hole 9 on the slider 8 and is connected to the float 4.

[0040] The cable storage assembly also includes a fixing ring 15, a connecting rod 16, and a threaded screw 17. A mounting block 18 is fixedly installed on the top of the trough box 1. The threaded screw 17 is arranged along the length of the second slide groove 13 and is rotatably mounted on the mounting block 18. The moving rod 5 extends upward through a rectangular through hole 14. The fixing ring 15 is fixedly sleeved on the top of the moving rod 5. One end of the connecting rod 16 is fixedly installed on the fixing ring 15, and the other end is threaded onto the threaded screw 17. When the float 4 rises, the electronic control system drives the threaded screw 17 to rotate. The rotation of the threaded screw 17 can drive the connecting rod 16 and the fixing ring 15 to move horizontally from right to left. Consequently, the moving rod 5 will be moved from right to left. The movement of the moving rod 5 from right to left will cause the cable 3 to be stored in the second slide groove 13 and the receiving groove 19. For the setting of the electric control system to drive the moving rod 5 to move horizontally, a drive motor (not shown in the figure) can be set on the trough box 1. The drive motor is used to drive the threaded screw 17 to rotate, and the rotation of the threaded screw 17 can drive the moving rod 5 to move horizontally.

[0041] The electrical control system can be any applicable computing device, such as a personal computer, server, programmable controller, microcontroller, etc., or it can be an integration of computer devices. The electrical control system has functions such as receiving information and sending control commands. The electrical control system can control the pump body 20 and the drive motor to perform corresponding actions through wired or wireless communication to realize the horizontal movement of the moving rod 5.

[0042] The working principle of this invention is as follows: When the float 4 floats to the liquid surface of the tank 1, the external electrical control system (not shown in the figure) controls the pump 20 to stop conveying the material into the tank 1, and the discharge pipe 22 can be opened to release the material; when the liquid level in the tank 1 is low, the float 4 will sink to the bottom of the tank 1, at which time the electrical control system will start the pump 20 to convey the material into the tank 1. During the process of pump body 20 conveying materials into tank 1, float 4 will rise with the rise of material liquid level. At this time, cable 3 will be in a floating state. In order to prevent cable 3 from getting tangled and floating above float 4 and blocking float 4 from working normally up and down, the electrical control system will start drive motor (not shown in the figure). Drive motor will drive threaded screw 17 to rotate. Then, during the process of float 4 rising, the rotation of threaded screw 17 will drive moving rod 5 to move from right to left. During this process, moving rod 5 can pull cable 3 to store cable 3, so that cable 3 will not get tangled and float above float 4, ensuring the normal operation of float 4.

[0043] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
