Description

Technical Field

[0001] This utility model relates to the technical field of status sensing devices for discharge valves, specifically a status sensing device for a discharge valve of a mixer. Background Technology

[0002] A mixer discharge valve is a key component installed at the bottom or side of a mixer to control the discharge of the mixture. Its function is to precisely and quickly discharge materials from the mixer through the valve, facilitating subsequent production processes or packaging. This valve is typically made of high-strength, wear-resistant, and corrosion-resistant materials, capable of withstanding the chemical properties and mechanical stresses of different materials.

[0003] However, the existing discharge valve of the mixer is prone to errors when operated manually. There are also cases where the valve is forgotten to be closed after maintenance, resulting in the discharge valve not being closed in time. Personnel cannot keep track of the opening and closing status of the discharge valve, which can lead to unexpected material leakage in the mixer and waste of material. Therefore, the current discharge valve of the mixer needs to be improved. Utility Model Content

[0004] The purpose of this invention is to provide a status sensing device for the discharge valve of a mixer to solve the problems currently found in the market as described in the background.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a status sensing device for a discharge valve of a mixer, comprising a discharge pipe welded to one side of the discharge valve body, a fixing plate welded to the lower part of the discharge valve body, and a base frame connected to the lower part of the fixing plate by bolts;

[0006] The base frame is fixed above one end of the discharge valve body with a mounting bracket that supports the photoelectric sensor. The photoelectric sensor that can sense the position of the discharge valve body handle extends through the inner side of the mounting bracket. The sensing end of the photoelectric sensor is close to the handle of the discharge valve body. The photoelectric sensor is a non-contact limit switch.

[0007] The mounting bracket has a connecting plate welded to one side above the photoelectric sensor, and a limiting mechanism that restricts the rotation of the discharge valve handle is installed on the inner side of the connecting plate.

[0008] Preferably, a mixing machine body for mixing materials is welded to the top of the feeding pipe.

[0009] Preferably, the mounting bracket is equipped with a winding rod for winding the wire harness on one side below the photoelectric sensor, and the outer side of the winding rod is provided with equally spaced annular grooves.

[0010] Preferably, the limiting mechanism includes a slider located inside the connecting plate, and the connecting plate has a groove inside which the slider can slide laterally, and both the slider and the groove have a T-shaped cross-section.

[0011] Preferably, a slide rod is fixed inside the slide groove to form a sliding sleeve structure with the slider, and a support spring that can reset the slider is sleeved on the outside of the slide rod.

[0012] Preferably, side plates are fixed on both sides of the slider, and a rotating shaft is fixed at the center of the side plates.

[0013] Preferably, a rotating block that drives the limiting ring to rotate is movably sleeved outside the rotating shaft, and one end of the rotating block is connected to the limiting ring. The slider is located on the outer surface below the side plate and has a pull rod that is easy to push and pull manually.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The status sensing device of the discharge valve of the mixer has a mounting bracket to support the photoelectric sensor. The photoelectric sensor is a non-contact limit switch that can sense the position of the handle of the discharge valve body and feed the signal back to the central control to realize intelligent monitoring. By installing the photoelectric sensor on one side of the discharge valve body, real-time monitoring and abnormal warning of the manual valve can be realized, preventing the discharge valve body from being opened accidentally or forgotten to be closed, reducing material waste, improving efficiency, facilitating management, and reducing the risk of human error.

[0016] 2. The status sensing device of the discharge valve of the mixer has a limiting mechanism to limit the handle of the discharge valve body, reducing the possibility of accidental opening. The combination of the limiting mechanism and the photoelectric sensor improves the working quality of the status sensing device. If the wire of the photoelectric sensor is too long, the wire can be wound in the annular groove on the outside of the winding rod to increase the friction and prevent the long wire from becoming tangled.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-4 This utility model provides a technical solution: a status sensing device for a discharge valve of a mixer, including a feed pipe 2 welded to one side of the discharge valve body 1, a mixer body 3 for mixing welded to the top of the feed pipe 2, a fixing plate 10 welded to the bottom of the discharge valve body 1, a base frame 9 connected to the bottom of the fixing plate 10 by bolts, a mounting bracket 4 for supporting a photoelectric sensor 5 fixed above one end of the base frame 9, and a photoelectric sensor 5 that can sense the position of the handle of the discharge valve body 1 extending through the inner side of the mounting bracket 4, the sensing end of the photoelectric sensor 5 being close to the handle of the discharge valve body 1, and the photoelectric sensor 5 being a non-contact limit switch.

[0025] In practice, the mixing machine body 3 discharges the mixed material from the discharge pipe 2. The discharge valve 1 controls the material discharge. During the discharge process, the handle needs to be manually rotated to open and close the discharge valve 1. To facilitate monitoring of the position of the discharge valve 1, the base frame 9 can be installed under the fixed plate 10 with bolts, and the mounting bracket 4 supports the photoelectric sensor 5. The photoelectric sensor 5 is a non-contact limit switch that can sense the position of the handle of the discharge valve 1 and feed the signal back to the central control to achieve intelligent monitoring. By installing the photoelectric sensor 5 on one side of the discharge valve 1, real-time monitoring and abnormal warning of the manual valve can be achieved, preventing the discharge valve 1 from being opened accidentally or forgotten to be closed, reducing material waste, improving efficiency, facilitating management, and reducing the risk of human error.

[0026] Please see Figures 1-4The mounting bracket 4 has a connecting plate 7 welded to one side above the photoelectric sensor 5. A limiting mechanism 6 that restricts the rotation of the handle of the discharge valve body 1 is installed on the inner side of the connecting plate 7. A winding rod 8 for winding the wire harness is installed on the side of the mounting bracket 4 below the photoelectric sensor 5, and an equally spaced annular grooves are provided on the outer side of the winding rod 8.

[0027] In practice, based on the sensing of the photoelectric sensor 5, the limit mechanism 6 is used to limit the handle of the discharge valve body 1 to reduce the possibility of accidental opening and improve the working quality of the status sensing device. If the wire of the photoelectric sensor 5 is too long, the wire can be wound in the annular groove on the outside of the winding rod 8 to increase the friction and prevent the long wire from becoming tangled.

[0028] Please see Figures 2-5 The limiting mechanism 6 includes a slider 606 located inside the connecting plate 7. The connecting plate 7 has a groove 13 inside which the slider 606 can slide laterally. Both the slider 606 and the groove 13 have a T-shaped cross-section. A sliding rod 12 is fixed inside the groove 13 and forms a sliding sleeve structure with the slider 606. A support spring 11 is sleeved on the outside of the sliding rod 12 to reset the slider 606.

[0029] Both sides of the slider 606 are fixed with side plates 602. A rotating shaft 604 is fixed at the axis of the side plate 602. A rotating block 605 that drives the limiting ring 603 to rotate is movably sleeved on the outside of the rotating shaft 604. One end of the rotating block 605 is connected to the limiting ring 603. A pull rod 601 that is easy to push and pull manually is fixed on the outer surface of the slider 606 below the side plate 602.

[0030] In practice, before closing the discharge valve body 1, the lever 601 can be pulled, causing the lever 601 to drive the slider 606 to slide laterally within the slide groove 13. Simultaneously, the slider 606 slides on both sides outside the slide rod 12 and compresses the support spring 11, causing the support spring 11 to contract. Then, the limiting ring 603 is rotated, causing the limiting ring 603 to drive the rotating block 605 to rotate 180 degrees clockwise around the rotating shaft 604. After closing the discharge valve body 1, the handle of the discharge valve body 1 is in a vertical position. At this time, the opening direction of the limiting ring 603 is aligned with the handle of the discharge valve body 1. Then, the lever is released. 601 causes the support spring 11 to rebound, driving the slider 606 to reset. At the same time, the slider 606 drives the limiting ring 603 to be sleeved on the outside of the handle of the discharge valve body 1, restricting the rotation of the handle of the discharge valve body 1. The slider 606 and the slide groove 13, which have a T-shaped cross-section, allow the slider 606 to move laterally stably without detachment. The limitation of the limiting ring 603 can prevent the handle of the discharge valve body 1 from rotating unexpectedly due to vibration of the mixer body 3 or external collision, reducing material leakage. Combined with the photoelectric sensor 5, it can improve the stability of the status sensing device.

[0031] Working principle: When using the status sensing device of the discharge valve of the mixer, the base frame 9 is first installed on the fixed plate 10 with bolts, so that the photoelectric sensor 5 is close to the discharge valve body 1 to monitor the position status of the discharge valve body 1. The limit mechanism 6 limits the handle of the discharge valve body 1 to prevent accidental opening. The winding rod 8 can wind the long wire of the photoelectric sensor 5, which improves the stability and working quality of the status sensing device. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0032] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
