Description

Technical Field

[0001] This utility model relates to the field of kneading machine technology, and in particular to a kneading machine with a real-time liquid level monitoring mechanism. Background Technology

[0002] Kneaders are a type of mixing equipment widely used in industries such as chemicals, rubber, plastics, and food. In the actual operation of a kneader, adding powder first and then liquid can easily lead to localized clumping, dust, and difficulty in achieving uniform mixing. It is often necessary to add liquid additives or solvents into the cylinder first, and then add the powder to avoid phenomena such as bridging, clumping, and dust.

[0003] In the production application of kneaders, it is usually necessary to add liquid materials and solid or powder materials. Generally, liquid materials are added first. The advantages of this are: 1. Powder falling into the liquid is immediately wetted, avoiding dust. 2. It is easy to disperse, preventing powder from clumping ("fish eyes" or "dry powder balls"). Some kneaders may use direct float level gauges or external ultrasonic level gauges. Although these level gauges can effectively display the liquid level, they cannot provide timely warnings when the liquid level exceeds the threshold, and it is inconvenient to pre-set the threshold or disable the warning function according to different raw materials. Therefore, we have improved this by providing a kneader with a real-time liquid level monitoring mechanism. Utility Model Content

[0004] Therefore, it is necessary to provide a kneader with a real-time liquid level monitoring mechanism to address the above-mentioned technical problems, so as to realize adjustable automatic liquid level warning and drainage.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A kneader with a real-time liquid level monitoring mechanism includes a kneader body, the kneader body including a cylinder, a stirring blade disposed within the cylinder, a drive mechanism for driving the stirring blade, and a cylinder cover covering the top of the cylinder. An electromagnetic valve communicating with the cylinder is also installed on the outer wall of the cylinder, and an alarm is also installed on the outer wall of the cylinder. The kneader body further includes:

[0007] The liquid level monitoring mechanism includes a liquid level monitoring bracket fixedly mounted on the cylinder body and a display rod slidably mounted on the liquid level monitoring bracket, wherein a material level display float is fixedly connected to the bottom of the display rod;

[0008] A locking sleeve is fixedly installed on the top of the liquid level monitoring bracket to secure the display rod;

[0009] The signal conversion module includes a motion sensing unit fixedly installed on the top of the display pole and a fixed sensing unit corresponding to and cooperating with the motion sensing unit. The fixed sensing unit adjusts the distance between itself and the cylinder body through a sliding rod.

[0010] The motion sensing unit and the part that comes into contact with the motion sensing unit are used to output alarm and / or drainage control commands.

[0011] Furthermore, the outer wall of the display rod has scale lines, and the side wall of the locking sleeve is threaded with fixing bolts for fixing the display rod.

[0012] Furthermore, the motion sensing unit includes a motion sensing module, and an alarm motion contact and a drain motion contact are respectively installed at both ends of the motion sensing module.

[0013] Furthermore, the fixed sensing unit includes a fixed sensing module, and the side wall of the fixed sensing module is fixedly connected to the alarm fixed contact and the drain fixed contact of the corresponding moving sensing module. The alarm moving contact and the drain moving contact, as well as the alarm fixed contact and the drain fixed contact, are all conductive metal springs.

[0014] Furthermore, a cutting mechanism is slidably mounted on the fixed sensing module, which can slide within the fixed sensing module to switch between the connected position and the cut-off position.

[0015] Furthermore, the cutting mechanism includes an insulating plate, which is elastically engaged with the fixed sensing module via a hook spring.

[0016] Furthermore, the insulating card plate is provided with a double track slide groove, which has a straight section slide groove and an inclined section slide groove, and the straight section slide groove and the inclined section slide groove are connected to each other. The inner side wall of the fixed sensing module has a limiting protrusion that slides with the double track slide groove.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] This utility model provides a kneading machine with a real-time liquid level monitoring mechanism.

[0019] When liquid additives or solvents are added to the kneader, operators can choose to enable or disable the automatic alarm / drainage function according to production needs. The cutting mechanism set on the fixed sensor module can quickly switch between the "connected position" (energized when the moving / fixed contact is in contact) and the "cut-off position" (isolated contact by the insulating plate) through the cooperation of the insulating plate and the double track slide. It adopts a mechanical float + contact sensing structure, which does not require complex electronic components or external power supply signal processing system, thus reducing manufacturing costs and reducing failure points. The solenoid valve and alarm directly control the circuit through the contact, which is fast and easy to maintain. It achieves dynamic monitoring of the amount of liquid added before kneading. After the liquid level is reached, the excess liquid can be directly discharged for later use, realizing quantitative liquid addition before kneading and preventing the product molding from being affected by excessive liquid addition.

[0033] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 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 should fall within the protection scope of the present invention.

[0034] Example 1

[0035] Please refer to Figure 1-7 A kneading machine with a real-time liquid level monitoring mechanism, comprising:

[0036] The kneader body 1 includes a cylinder 11, a stirring blade 12 disposed within the cylinder 11, a drive mechanism 13 for driving the stirring blade 12, and a cylinder cover 14 covering the top of the cylinder 11. A solenoid valve 15 communicating with the cylinder 11 is also installed on the outer wall of the cylinder 11. An alarm 16 is also installed on the outer wall of the cylinder 11. The stirring blade 12 is rotatably mounted inside the cylinder 11 via bearings. The drive mechanism 13 includes a drive motor, which drives a gearbox via a pulley. The gearbox is connected to the shaft of the stirring blade 12 via a coupling. The cylinder cover 14 is snap-fitted to the cylinder 11 for easy disassembly and maintenance. The alarm 16 is a buzzer or warning light. The kneader body 14 also includes:

[0037] The liquid level monitoring mechanism 2 includes a liquid level monitoring bracket 21 fixedly installed on the cylinder 11 and a display rod 23 slidably installed on the liquid level monitoring bracket 21. The bottom of the display rod 23 is fixedly connected to a material level display float 22. The display rod 23 passes through the cylinder 11 from the inside and extends to the outside of the cylinder 11. The side wall of the display rod 23 has a sliding groove. The liquid level monitoring bracket 21 has a slider to limit the rotation of the display rod 23.

[0038] The locking sleeve 3 is fixedly installed on the top of the liquid level monitoring bracket 21 to fix the display rod 23. The locking sleeve 3 also includes a fixing bolt with a threaded connection on the outer wall. The fixing bolt passes through the locking sleeve 3 and is threadedly fixed to the display rod 23.

[0039] The signal conversion module 4 includes a motion sensing unit 41 fixedly installed on the top of the display rod 23 and a fixed sensing unit 42 corresponding to the motion sensing unit 41. The fixed sensing unit 42 adjusts the distance between itself and the cylinder 11 through a sliding rod 43.

[0040] The motion sensing unit 41 and the solenoid valve 15 are used to output alarm and / or drainage control commands when in contact with the motion sensing unit 41. The solenoid valve 15 and the alarm 16 are connected in parallel to the power supply and the motion sensing unit 41 through wires.

[0041] Example 2

[0042] The kneader with a real-time liquid level monitoring mechanism provided in Embodiment 1 is further optimized. Specifically, the outer wall of the material level display float 22 has scale lines, and a sliding sleeve 44 adapted to the sliding rod 43 is installed on the fixed sensing unit 42. The sliding sleeve 44 is fixed to the outer wall of the sliding rod 43 by a locking bolt 45 that passes through the side wall.

[0043] Tightening the locking bolt 45 on the side wall will lock the fixed sensing unit 42 at any height of the slide bar 43. By loosening the locking bolt 45 and sliding the fixed sensing unit 42 up and down, the specific liquid level height for triggering drainage and triggering alarm can be precisely set.

[0044] Example 3

[0045] Example 3 further optimizes the kneader with a real-time liquid level monitoring mechanism provided in Example 2. The motion sensing unit 41 includes a motion sensing module 411, and alarm motion contact 412 and liquid discharge motion contact 413 are respectively installed at both ends of the motion sensing module 411.

[0046] The fixed sensing unit 42 includes a fixed sensing module 421. The side wall of the fixed sensing module 421 is fixedly connected to the alarm fixed contact 422 and the drain fixed contact 423 corresponding to the dynamic sensing module 411. The alarm dynamic contact 412 and the drain dynamic contact 413, as well as the alarm fixed contact 422 and the drain fixed contact 423, are all conductive metal springs.

[0047] Specifically, during the initial liquid addition process in the kneader, the material level display float 22 will float on the liquid. The liquid will push the material level display float 22 to float up. The operator can intuitively grasp the current liquid level by observing the scale line on the outer wall of the display rod 23. At this time, the dynamic sensing unit 41 moves up accordingly, but does not touch the fixed sensing unit 42. The solenoid valve 15 and the alarm 16 are both in the de-energized state.

[0048] When the liquid level reaches the set drainage height, the display rod 23 drives the motion sensor module 411 to continue moving upward, and the alarm moving contact 412 at its lower end contacts and closes with the alarm fixed contact 422. At this time, the alarm control circuit is turned on, the alarm is powered on, and the staff is alerted.

[0049] When the liquid level reaches the set drainage height, the display rod 23 drives the motion sensor module 411 to continue moving upward. The drainage moving contact 413 at its lower end contacts and closes with the drainage fixed contact 423. At this time, the drainage control circuit is turned on, the solenoid valve 15 is energized and opens, and the cylinder 11 starts to drain automatically. As the liquid level drops, the float falls, the contacts separate, and the solenoid valve 15 closes, thus achieving automatic maintenance of the liquid level.

[0050] In order to achieve the purpose of alarming before liquid discharge, the alarm moving contact 412 is higher than the liquid discharge moving contact 413. After the liquid is added, the fixing bolts on the outer wall of the locking sleeve 3 can be tightened to fix the entire material level display float 22 to the inner top wall of the cylinder 11, so as not to affect the kneading action.

[0051] Example 4

[0052] The kneading machine with a real-time liquid level monitoring mechanism provided in Embodiment 3 is further optimized. A cutting mechanism 5 is slidably installed on the fixed sensing module 421. The cutting mechanism 5 can slide within the fixed sensing module 421 to achieve switching between the connected position and the cut-off position.

[0053] The cutting mechanism 5 includes an insulating plate 51, which is elastically engaged with the fixed sensing module 421 via a hook spring 52. The insulating plate 51 has a double track groove 53, which has a straight section and an oblique section, and the straight section and the oblique section are connected. The inner sidewall of the fixed sensing module 421 has a limiting protrusion 54 that slides with the double track groove 53.

[0054] Specifically, the hook spring 52 provides the insulating plate 51 with inward contraction elastic potential energy. The switching insulating plate 51 has two movable positions. First, it is located between the moving contact and the fixed contact. Due to the insulation characteristics of the insulating plate 51, the two moving contacts and the fixed contact are isolated. Second, it is located to the side of the moving contact and the fixed contact. At this time, the circuit can be connected when the moving contact touches the fixed contact. Therefore, the operator can rotate it to determine whether drainage is required or selective drainage is possible, as well as whether to activate the liquid level alarm.

[0055] The position switching of the insulating plate 51 is achieved through the double-track slide 53. It is in an insulating state in the straight section of the slide and in a power-enabled state in the inclined section of the slide.
