Description

Technical Field

[0001] This utility model relates to the field of quantitative dispensing technology, and in particular to an adjustable quantitative dispensing device. Background Technology

[0002] In many fields such as industrial production, chemical industry, and food, the quantitative filling operation of media is crucial. Its accuracy directly affects product quality, production efficiency and cost control. In the use of high viscosity fluids (such as grease and glue), volumetric metering valves are usually used for industrial filling. Metering valves are widely used because of their convenient and durable volume measurement characteristics.

[0003] When adjusting the metering valve, the filling amount is mostly controlled by manually adjusting the metering valve. The operator needs to manually rotate the adjusting part of the metering valve to change the size of the internal flow channel, thereby adjusting the flow rate of the filling medium. This adjustment method is not only inefficient, but also prone to inaccurate filling amount due to human operation differences, making it difficult to meet the high-precision production requirements. Therefore, there is an urgent need for an adjustable metering filling device to solve the above problems. Utility Model Content

[0004] To overcome the shortcomings of the prior art, this utility model provides an adjustable quantitative dispensing device, which solves the technical problems of errors and low efficiency in manually adjusting the quantitative valve, making it difficult to meet the high-precision production requirements.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0006] An adjustable metering dispensing device includes: a base plate, wherein the base plate is provided with the following sequentially arranged in the X direction:

[0007] A metering valve, the metering valve comprising: an adjusting rod, the adjusting rod being used to adjust the injection volume of the injection medium;

[0008] An adjusting assembly includes: a movable block and a mounting rod. The movable block is sleeved on the mounting rod and threadedly connected to the mounting rod. One end of the movable block near the metering valve is connected to the adjusting rod. A measuring mechanism is installed on the movable block for measuring the relative displacement of the movable block.

[0009] A drive device, the drive end of which is connected to the mounting rod via a coupling assembly, is used to drive the mounting rod to rotate so as to move the moving block axially.

[0010] Based on the above structure, the principle of the adjustable quantitative dispensing device is as follows: When the dispensing device is needed for quantitative dispensing operations, the drive device is started, and power is transmitted to the mounting rod through the coupling assembly, causing the mounting rod to rotate. The coupling assembly is used to connect the drive device and the mounting rod, ensuring power transmission and preventing the connected components from bearing excessive loads, thus providing overload protection. When the mounting rod rotates, since the moving block is threadedly connected to the mounting rod, the end of the moving block near the quantitative valve is connected to the adjusting rod. The moving block will move axially along the mounting rod, and the axial movement of the moving block can drive the adjusting rod to move, thereby realizing the adjustment of the dispensing amount of the quantitative valve. The adjusting rod is used to change the internal structure or opening of the quantitative valve, thereby setting... Different filling volumes are achieved through a measuring mechanism mounted on the moving block. During operation, this mechanism monitors the movement of the moving block in real time. By measuring the displacement of the moving block, the displacement of the adjusting rod can be indirectly determined, thus displaying the degree of adjustment of the filling volume of the metering valve. This provides feedback information to the operator for more precise adjustments. For example, if the measuring mechanism shows that the moving block has moved a certain distance, based on previous calibration or settings, it can be determined how much the filling volume has changed accordingly. The drive device provides the power source for the entire adjustment process, enabling the moving block to move as needed. This achieves automatic adjustment of the filling volume of the metering valve, improving the efficiency and accuracy of adjustment and avoiding the errors and instabilities that may occur with manual adjustment.

[0011] Furthermore, in an adjustable quantitative dispensing device of this application, a mounting ring is provided at the connection between the moving block and the mounting rod. The mounting ring is detachably mounted on the moving block, sleeved on the moving block, and threadedly connected to the moving block. As a preferred embodiment of this application, after prolonged use, wear or jamming may occur at the connection between the moving block and the mounting rod. The detachable design of the mounting ring not only facilitates cleaning and maintenance of the connection but also allows for easy removal and replacement of the mounting ring when wear occurs between it and the mounting rod, avoiding the need to replace the entire moving block and thus improving the economic efficiency of the dispensing device.

[0012] Furthermore, in an adjustable quantitative dispensing device of this application, the coupling assembly includes: a mounting frame, the mounting frame being mounted on a base plate, a bearing being provided on the mounting frame, and the bearing being sleeved on a mounting rod. As a preferred embodiment of this application, in an adjustable quantitative dispensing device, the bearing is mounted on the mounting frame and sleeved on the mounting rod, ensuring accurate positioning of the mounting rod during rotation. This guarantees that the mounting rod rotates along a predetermined axis, avoiding radial offset and ensuring the stability of the moving block during axial movement of the mounting rod. Ultimately, this ensures the accuracy of the dispensing volume adjustment by the quantitative valve. Furthermore, the bearing significantly reduces friction during the rotation of the mounting rod, reducing wear between the mounting rod and the mounting frame, and extending the service life of the device.

[0013] Furthermore, in an adjustable quantitative dispensing device of this application, a guide post is provided on one side of the bearing near the moving block, the moving block is sleeved on the guide post, and a collar is provided between the moving block and the guide post. The collar is installed on the moving block and sleeved on the guide post. As a preferred embodiment of this application, in an adjustable quantitative dispensing device, when the driving device drives the mounting rod to rotate, causing the moving block to move axially along the mounting rod, the guide post provides guidance for the axial movement of the moving block, preventing the moving block from deviating or shaking during movement, ensuring the stability of the moving block's movement, and ensuring the adjustment accuracy of the dispensing amount by the adjusting rod; the collar is used to reduce the friction between the moving block and the guide post, reduce wear, extend the service life of the guide post and the moving block, and limit the moving block radially on the guide post.

[0014] Furthermore, in an adjustable quantitative dispensing device of this application, the mounting frame has a mounting port, and a mounting seat is provided inside the mounting port. The bearing is mounted on the mounting seat, and the mounting seat has an extension on the side away from the adjusting component. The extension extends radially along the mounting rod. When the mounting seat is installed in the mounting port, the extension and the mounting frame are axially engaged with each other in the mounting rod. As a preferred embodiment of this application, the mounting seat provides a stable mounting position for the bearing. When the bearing needs to be replaced, the operator can pull the entire mounting seat and bearing out of the mounting port, avoiding disassembly of the mounting frame and facilitating its maintenance. Furthermore, when different specifications of bearings are required, only the mounting seat compatible with the bearing needs to be replaced, instead of replacing the entire mounting frame, thus improving the device's scalability. The extension and the end face of the mounting frame are engaged axially with the mounting rod, preventing the mounting seat from loosening or shifting in the axial direction of the mounting rod, improving structural stability. At the same time, when the mounting seat is assembled onto the mounting frame, the extension and the end face of the mounting frame cooperate to prevent misalignment or tilting of the mounting seat.

[0015] Furthermore, in one adjustable metering dispensing device of this application, the measuring mechanism includes a sensing and detection unit mounted on a moving block, the measuring head of which is used to detect the relative displacement of the moving block. As a preferred embodiment of this application, in this adjustable metering dispensing device, when the driving device drives the mounting rod to rotate, causing the moving block to move axially along the mounting rod, the sensing and detection unit can measure the distance the moving block moves relative to the metering valve body. The operator can then determine whether the current adjustment degree of the adjusting rod has reached a preset value based on the measured displacement data. If not, the driving device can be further controlled to continue moving the moving block to adjust the adjusting rod; if the set value has been reached or exceeded, the driving device can be stopped or reversed to adjust the position of the moving block, ensuring that the adjusting rod is in the preset position.

[0016] Furthermore, the adjustable quantitative dispensing device of this application also includes a limit sensor, which is installed on the mounting frame near the adjusting component. The detection direction of the limit sensor is set towards the movement path of the moving block. The limit sensor is used to stop the drive device from driving the mounting rod to rotate when the moving block enters its preset detection range. As a preferred embodiment of this application, the adjustable quantitative dispensing device of this application uses the limit sensor as a safety limit mechanism to prevent the moving block from getting too close to the mounting frame, which could lead to mechanical interference or damage. When the moving block moves axially along the mounting rod under the drive of the drive device and enters the detection range of the limit sensor, the limit sensor triggers an electrical signal, causing the drive device to stop immediately, thereby preventing the moving block from hitting the mounting frame and improving the safety of the dispensing device.

[0017] As can be seen from the above technical solution, this utility model has the following beneficial effects:

[0018] The purpose of this invention is to provide an adjustable quantitative dispensing device. The axial displacement of the moving block is adjusted by driving the mounting rod to rotate through the driving device. The measuring mechanism can monitor the displacement of the moving block in real time. The device adopts a detachable mounting ring, guide post and collar guiding structure, as well as a stable transmission design of the coupling assembly. This solves the problems of low efficiency and low accuracy of manual adjustment, realizes the automated and precise adjustment of the dispensing amount of the quantitative valve, and improves the stability and ease of maintenance of the device.

Detailed Implementation

[0024] like Figure 1 , 2 As shown, an adjustable quantitative dispensing device includes: a base plate 1, on which the following are arranged sequentially in the X direction:

[0025] A metering valve 2, comprising: an adjusting rod 21, the adjusting rod 21 being used to adjust the amount of the injection medium;

[0026] Adjustment component 3 includes: a moving block 31 and a mounting rod 32. The moving block 31 is sleeved on the mounting rod 32 and is threadedly connected to the mounting rod 32. One end of the moving block 31 near the metering valve 2 is connected to the adjustment rod 21. A measuring mechanism 4 is installed on the moving block 31 for measuring the relative displacement of the moving block 31.

[0027] The driving device 5 is connected to the mounting rod 32 via a coupling assembly 6. The driving device 5 is used to drive the mounting rod 32 to rotate so as to drive the moving block 31 to move axially.

[0028] Based on the above structure, the principle of the adjustable quantitative dispensing device is as follows: When the dispensing device is needed for quantitative dispensing, the drive device 5 is started, and power is transmitted to the mounting rod 32 through the coupling assembly 6, causing the mounting rod 32 to rotate. The coupling assembly 6 is used to connect the drive device 5 and the mounting rod 32, ensuring power transmission and preventing the connected components from bearing excessive load, thus providing overload protection. When the mounting rod 32 rotates, since the moving block 31 is threadedly connected to the mounting rod 32, and the end of the moving block 31 near the quantitative valve 2 is connected to the adjusting rod 21, the moving block 31 will move axially along the mounting rod 32. The axial movement of the moving block 31 can drive the adjusting rod 21 to move, thereby realizing the adjustment of the dispensing amount of the quantitative valve 2. The adjusting rod 21 is used to change the internal structure of the quantitative valve 2. The valve opening can be adjusted to set different filling amounts. A measuring mechanism 4 mounted on the moving block 31 monitors the movement of the moving block 31 in real time during use. By measuring the displacement of the moving block 31, the displacement of the adjusting rod 21 can be indirectly determined, thus displaying the degree of adjustment of the filling amount of the metering valve 2. This provides feedback information to the operator for more precise adjustment. For example, if the measuring mechanism 4 shows that the moving block 31 has moved a certain distance, based on previous calibration or settings, the corresponding change in filling amount can be determined. The drive device 5 provides the power source for the entire adjustment process, enabling the moving block 31 to move as needed, thereby achieving automatic adjustment of the filling amount of the metering valve 2. This improves the efficiency and accuracy of adjustment and avoids the errors and instability that may occur with manual adjustment. The drive device 5 uses a servo motor, and the mounting rod 32 uses a trapezoidal lead screw. Correspondingly, the moving block 31 has a thread adapted to the trapezoidal lead screw.

[0029] In this embodiment, a mounting ring 30 is provided at the connection between the moving block 31 and the mounting rod 32. The mounting ring 30 is detachably mounted on the moving block 31, sleeved on the moving block 31, and threadedly connected to the moving block 31. After prolonged use, wear or jamming may occur at the connection between the moving block 31 and the mounting rod 32. The detachable design of the mounting ring 30 not only facilitates cleaning and maintenance of the connection, but also allows for easy removal and replacement of the mounting ring 30 when wear occurs between it and the mounting rod 32, avoiding the need to replace the entire moving block 31, thus improving the economy of the filling device. The mounting ring 30 is mounted on the moving block 31 by screws (not shown).

[0030] In this embodiment, as Figure 3As shown, the coupling assembly 6 includes: a mounting bracket 61, which is mounted on a base plate 1. A bearing 62 is mounted on the mounting bracket 61 and sleeved on a mounting rod 32. The bearing 62, mounted on the mounting bracket 61 and sleeved on the mounting rod 32, ensures accurate positioning of the mounting rod 32 during rotation, guaranteeing its rotation along a predetermined axis and preventing radial offset. This ensures the stability of the moving block 31 during axial movement of the mounting rod 32, ultimately guaranteeing the accuracy of the metering valve 2's filling volume adjustment. Furthermore, the bearing 62 significantly reduces friction during the rotation of the mounting rod 32, reducing wear between the mounting rod 32 and the mounting bracket 61, and extending the device's service life. The bearing 62 is a ball bearing.

[0031] In this embodiment, as Figure 4 As shown, a guide post 621 is provided on one side of the bearing 62 near the moving block 31. The moving block 31 is sleeved on the guide post 621. A collar 7 is provided between the moving block 31 and the guide post 621. The collar 7 is mounted on the moving block 31 and sleeved on the guide post 621. When the driving device 5 drives the mounting rod 32 to rotate, causing the moving block 31 to move axially along the mounting rod 32, the guide post 621 provides guidance for the axial movement of the moving block 31, preventing the moving block 31 from deviating or shaking during movement, ensuring the stability of the moving block 31's movement, and ensuring the adjustment accuracy of the adjusting rod 21 for the filling amount. The collar 7 is used to reduce the friction between the moving block 31 and the guide post 621, reduce wear, extend the service life of the guide post 621 and the moving block 31, and limit the moving block 31 radially on the guide post 621. The guide post 621 is mounted on the mounting bracket 61 by screws (not shown).

[0032] In this embodiment, the mounting bracket 61 is provided with a mounting opening 610, and a mounting seat 63 is provided inside the mounting opening 610. The bearing 62 is mounted on the mounting seat 63. The mounting seat 63 has an extension 631 on the side away from the adjusting component 3. The extension 631 extends radially along the mounting rod 32. When the mounting seat 63 is installed in the mounting opening 610, the extension 631 and the mounting bracket 61 are axially engaged with each other in the mounting rod 32. The mounting seat 63 provides a stable mounting position for the bearing 62. When the bearing 62 needs to be replaced, the operator can remove the mounting seat 63 and the bearing 62 as a whole from the mounting bracket. The mounting bracket 61 is retractable from the opening 610, avoiding disassembly of the mounting frame 61 and facilitating its maintenance. Furthermore, when different specifications of bearings 62 are required, only the mounting seat 63 compatible with the bearing 62 needs to be replaced, instead of replacing the entire mounting frame 61, thus improving the device's scalability. The extension 631 and the end face of the mounting frame 61 are axially engaged with the mounting rod 32, preventing the mounting seat 63 from loosening or shifting in the axial direction of the mounting rod 32, improving structural stability. Simultaneously, when assembling the mounting seat 63 onto the mounting frame 61, the extension 631 mates with the end face of the mounting frame 61, preventing misalignment or tilting of the mounting seat 63. The mounting seat 63 is mounted on the mounting frame 61 using screws (not shown).

[0033] In this embodiment, the measuring mechanism 4 includes a sensing and detection unit 41, which is mounted on the moving block 31. The measuring head of the sensing and detection unit 41 is used to detect the relative displacement of the moving block 31. When the driving device 5 drives the mounting rod 32 to rotate, causing the moving block 31 to move axially along the mounting rod 32, the sensing and detection unit 41 can measure the distance the moving block 31 moves relative to the valve body of the metering valve 2. The operator can determine whether the adjustment degree of the adjusting rod 21 has reached the preset value based on the measured displacement data. If it has not reached the preset value, the driving device 5 can be further controlled to make the moving block 31 continue to move to adjust the adjusting rod 21. If the preset value has been reached or exceeded, the driving device 5 can be stopped or reversed to adjust the position of the moving block 31 to ensure that the adjusting rod 21 is in the preset position. The sensing and detection unit 41 uses a distance sensor, and the measuring head of the sensing and detection unit 41 is set facing the valve body of the quantitative valve 2; in other embodiments, the measuring mechanism 4 uses a magnetic scale, which includes a reading head and a magnetic scale. The magnetic scale is set on the base plate 1, and the setting direction of the magnetic scale is the same as the movement direction of the moving block 31. The reading head is set above the magnetic scale and is connected to the moving block 31.

[0034] This embodiment also includes a limit sensor 8, which is installed on the mounting bracket 61 near the adjustment assembly 3. The detection direction of the limit sensor 8 is set towards the movement path of the moving block 31. The limit sensor 8 is used to stop the drive device 5 from driving the mounting rod 32 to rotate when the moving block 31 enters its preset detection range. The limit sensor 8 acts as a safety limiting mechanism to prevent the moving block 31 from getting too close to the mounting bracket 61, thus preventing mechanical interference or damage. When the moving block 31 moves axially along the mounting rod 32 under the drive of the drive device 5 and enters the detection range of the limit sensor 8, the limit sensor 8 triggers an electrical signal, causing the drive device 5 to stop immediately, thereby preventing the moving block 31 from colliding with the mounting bracket 61 and improving the safety of the filling device. The limit sensor 8 uses a photoelectric proximity switch.
