Description

Technical Field

[0001] This utility model relates to the field of injection equipment technology, specifically to an embedded pressure sensor quadruple injection pump. Background Technology

[0002] In the traditional field of syringe pumps, single-station syringe pumps are widely used in various liquid delivery applications. Although existing technologies have multi-station syringe pumps, the inlet and multiple outlet flow channels of multi-station syringe pumps are independent and separate. To ensure stable performance, it is necessary to test the pressure resistance of each inlet separately.

[0003] Currently, multi-station syringe pumps rely on third-party testing methods to ensure their performance. This not only increases costs but also introduces a degree of uncontrollability. Especially when there are many flow channels, the testing process is cumbersome and prone to missed or repeated tests, thus failing to effectively guarantee product quality.

[0004] To address this, we propose an embedded pressure sensor quadruple injection pump. Utility Model Content

[0024] 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.

[0025] Example 1:

[0026] Please see Figures 1 to 5The technical solution provided by this utility model is as follows: an embedded pressure sensor quadruple injection pump, including an upper fixed base 9 and a lower fixed plate 13, the upper fixed base 9 and the lower fixed plate 13 are vertically aligned, a side sealing plate 8 is provided on one side of the upper fixed base 9 and the lower fixed plate 13, and a circuit board 16 is mounted on the upper fixed base 9 and the lower fixed plate 13; a front panel 2 is provided on one side of the upper fixed base 9 and the lower fixed plate 13, and a lower valve head 4 and an upper valve head 20 connected to each other are mounted on the front panel 2, and a protective cover 1 is provided on the front panel 2. The injection tube is connected to the lower valve head 4. A solenoid valve 21 is installed on the injection tube. The solenoid valve 21 is used to control and select the flow channel. It also includes a pressure sensor body 19. Multiple pressure sensor bodies 19 are respectively installed on the upper valve head 20 for detecting the liquid flow in the lower valve head 4 and the upper valve head 20. A pressure plate 18 is installed on the top of the pressure sensor body 19. The pressure plate 18 is connected to the upper valve head 20. A valve head cover 3 is installed on the front panel 2. The valve head cover 3 covers the upper valve head 20. Multiple preset elongated holes 7 are opened on the front panel 2.

[0027] In this embodiment, as Figure 2 and Figure 5 As shown, it also includes a moving mechanism 11, which includes a lead screw body 12 disposed between the lower fixed plate 13 and the upper fixed seat 9. A bearing body 28 is sleeved at the bottom end of the lead screw body 12. The bearing body 28 is fixedly connected to the lower fixed plate 13. The moving mechanism 11 is provided with a slider 15 and a screw sleeve 25. An installation groove 27 for placing the screw sleeve 25 is opened on the slider 15. The screw sleeve 25 is threadedly connected to the lead screw body 12 and fixedly connected to the slider 15. Multiple piston push rods 6 are provided on the slider 15, and a sensing plate 26 is provided on the slider 15.

[0028] Multiple glass tubes 5 are connected to the lower valve head 4, and multiple piston rods 6 pass through the preset elongated holes 7 respectively. The multiple piston rods 6 are connected to the glass tubes 5 respectively, and the piston rods 6 can move within the preset elongated holes 7.

[0029] The moving mechanism 11 also includes a transmission component 14 mounted on the lower fixed plate 13. The transmission component 14 includes a lead screw pulley 143 mounted on the lead screw body 12 and a drive motor 141 mounted on the lower fixed plate 13. A motor pulley 142 is mounted on the output end of the drive motor 141. A belt body 144 connects the lead screw pulley 143 and the motor pulley 142. When the drive motor 141 is activated in forward rotation mode, the drive motor 141 drives the lead screw body 12 to rotate in the forward direction, thereby forcing the slider 15 to move closer to the lower fixed plate 13. Fluid is drawn from the inlet through the valve head of the combination of the lower valve head 4 and the upper valve head 20, driving the piston push rod 6 to move downward, thereby realizing the liquid pumping action. Conversely, when the drive motor 141 is activated in reverse rotation mode, fluid is discharged from the outlet through the valve head of the combination of the lower valve head 4 and the upper valve head 20, thereby realizing the liquid pushing action, and is discharged from the middle port together. Each flow channel passes through the pressure sensor body 19 to transmit pressure signals and realize the detection function.

[0030] In this embodiment, as Figure 2 and Figure 5 As shown, a pair of guide rods 24 are also provided between the upper fixed seat 9 and the lower fixed plate 13. Both guide rods 24 are slidably connected to the slider 15. The two guide rods 24 are located on one side of the lead screw body 12. The guide rods 24 support the slider 15, so that the slider 15 has stability and avoids shaking during movement.

[0031] In this embodiment, as Figure 2 and Figure 5 As shown, a sensor 10 is provided on the upper fixed base 9, and an encoder body 22 connected to the lead screw body 12 is installed on the upper fixed base 9. The encoder body 22 is then rotated by the lead screw body 12. A bearing body 28 is also sleeved on the top of the lead screw body 12. A bearing cover 23 for limiting the bearing body 28 is provided on the upper fixed base 9. An encoder cover 17 is provided on the top of the upper fixed base 9, covering the outside of the encoder body 22. The rotation range of the lead screw body 12 can be intuitively displayed on the encoder body 22, which facilitates positioning by the staff and makes it easy to use.

[0032] The implementation principle of the embedded pressure sensor quadruple injection pump in this embodiment is as follows: When the drive motor 141 is activated in forward rotation mode, the drive motor 141 drives the lead screw body 12 to rotate in the forward direction, thereby forcing the slider 15 to move closer to the lower fixed plate 13. The fluid is drawn from the inlet through the valve head composed of the lower valve head 4 and the upper valve head 20, which drives the piston push rod 6 to move down, thereby realizing the pumping action. Conversely, when the drive motor 141 is activated in reverse rotation mode, the fluid is discharged from the outlet through the valve head composed of the lower valve head 4 and the upper valve head 20, thereby realizing the pushing action, and is discharged from the middle port together. Each flow channel passes through the pressure sensor body 19 to transmit pressure signals and realize the detection function.

[0033] Example 2:

[0034] Please see Figure 6 The technical solution provided by this utility model is as follows:

[0035] Unlike Embodiment 1, this solution provides another implementation of the transmission component 14: the transmission component 14 includes a drive motor 141 mounted on the lower fixed plate 13, a worm gear 145 mounted at the bottom end of the lead screw body 12, and a worm 146 meshing with the worm gear 145 mounted on the output end of the drive motor 141. When the drive motor 141 stops, the rotor will continue to rotate due to inertia, causing the lead screw body 12 to continue rotating, thus making precise adjustment impossible. However, the worm gear 145 and the worm 146 have a self-locking structural property. When the drive motor 141 stops, the self-locking property of the worm gear 145 and the worm 146 forces the rotor to rotate, thereby achieving more precise adjustment and improving practicality.
