Description

Technical Field

[0001] This utility model relates to the field of particulate matter sampling head assembly and disassembly technology, and in particular to a disassembly device for a particulate matter sampling head. Background Technology

[0002] The main function of a particulate matter sampling head is to collect particulate matter samples from the air for subsequent analysis and monitoring. A particulate matter sampling head generally consists of a sampling head body, a filter membrane, a support mesh, and an aluminum foil retainer, which are stacked together in sequence and then secured to the sampling head body, filter membrane, and support mesh by a clamping device.

[0003] Currently, after sampling, particulate matter sampling heads need to detect and calculate the particulate matter collected on the filter membrane to analyze air quality and ensure that the particulate matter concentration does not exceed the standard. However, currently, the entire particulate matter sampling head is weighed first, and then weighed again after sampling is completed. The weight of the sampled particulate matter is then compared to obtain the weight of the sampled particulate matter. However, particulate matter may also adhere to the inner tube of the particulate matter sampling head body during sampling, resulting in inaccurate actual particulate matter weight when the filter membrane is removed. When removing the filter membrane for weighing, the aluminum foil pressure ring is manually cut, and then the cut end of the aluminum foil pressure ring is clamped with a tool and pulled to detach the aluminum foil pressure ring. During this process, the particulate matter sampling head cannot maintain a stable state. When the aluminum foil pressure ring detaches, it may cause the filter membrane and support screen to fall off. Furthermore, it is not possible to keep the particulate matter sampling head horizontal to ensure that the filter membrane is level. This may cause particulate matter on the filter membrane to scatter, thus leading to inaccurate particulate matter sampling. The aluminum foil pressure ring needs to be peeled off very carefully, which affects efficiency. Utility Model Content

[0006] As a preferred embodiment, the edge of the particulate sampling head is suspended in the mounting groove near the disassembly slot. The telescopic power device includes a linear cylinder, which is fixedly mounted on the mounting platform. The telescopic gripper includes a gripper cylinder and a disassembly chuck, with the disassembly chuck fixedly mounted on the gripper cylinder's claw portion. The gripper cylinder is fixed to the piston rod of the linear cylinder via a gripper seat.

[0007] As a preferred embodiment, the pressure-down drive device includes a pressure-down base located next to the mounting platform. A column is vertically fixedly mounted on the pressure-down base. A guide rod is provided on the column. A sliding guide sleeve is fitted on the guide rod. A connecting rod is fixedly mounted on the guide sleeve. A drive mounting plate is fixedly mounted on the free end of the connecting rod. A pressure-down bracket is rotatably mounted on the bottom of the drive mounting plate. A contact drive block is provided at the lower part of the pressure-down bracket to contact and press down with the particulate matter sampling head. A drive power device for driving the pressure-down bracket to rotate is provided at the upper part of the drive mounting plate.

[0008] As a preferred embodiment, the pressure bracket includes three vertical pressure rods, the contact drive block is fixedly installed at the bottom of the pressure rods, the contact drive block is made of a material with high friction, and the pressure rods are rotatably connected to the drive mounting plate through a connecting seat.

[0009] As a preferred embodiment, the card box has sliding guides on both sides and outer edges that cooperate with the mounting box. The positioning structure is a positioning baffle, which is fixedly installed on the side of the mounting box to block the card box.

[0010] As a preferred embodiment, the cutting structure includes a cutting blade, and the side wall of the mounting housing is provided with a cutting relief groove for accommodating the cutting blade and the cutting relief groove is located directly above the edge of the mounting groove. The upper end of the cutting blade is hinged and installed in the cutting relief groove. The cutting relief groove is provided with a compression spring that is connected to the cutting blade and elastically swings. When the cutting blade is located in the cutting relief groove, a portion of the cutting blade remains outside the cutting relief groove.

[0011] As a preferred embodiment, the card holder is also provided with a handle for easy pulling.

[0012] After adopting the above technical solution, the effect of this utility model is as follows: The particulate sampling head disassembly device includes an installation platform, on which an installation box is fixedly installed. The installation box has an opening at the top and a sliding mounting box on its side. A positioning structure for blocking and positioning the mounting box is provided on the opposite side of the installation box. The mounting box has a vertical mounting groove for mounting the particulate sampling head. The opening size and the mounting groove size are the same. A movable support platform supporting the particulate sampling head and allowing it to rotate is movably installed on the mounting box within the mounting groove. A cutting structure for elastically extending and cutting the aluminum foil pressure ring is provided on the side wall of the installation box above the mounting groove. A pressing drive device for pressing down on the particulate sampling head and driving its rotation is provided above the mounting box. A device penetrating the installation box and extending through the same side is provided on the side wall of the installation box. The disassembly channel connects the card holder to the card holder groove. A telescopic gripper, which extends into the disassembly channel to hold the aluminum foil pressure ring, is telescopically installed in the corresponding direction. The telescopic gripper is driven by a telescopic power device. First, the sampled particulate matter sampling head is vertically inserted into the card holder groove from the opening. Then, the aluminum foil pressure ring is cut by the cutting structure. At this time, the telescopic power device drives the telescopic gripper to extend into the disassembly channel to hold the aluminum foil pressure ring. Then, the telescopic gripper retracts, and simultaneously, the downward-pressing drive device presses down on the particulate matter sampling head and rotates it. Combined with the retraction of the telescopic gripper, the aluminum foil pressure ring is effectively peeled off. The filter membrane and the support screen then fall stably onto the movable support platform. Only the particulate matter sampling head body needs to be removed for easy removal of the filter membrane. This device automatically peels off the aluminum foil pressure ring after the particulate matter sampling head is clamped, ensuring stable disassembly of the filter membrane and accurate sampling.

[0013] Furthermore, since the edge of the particulate sampling head is suspended near the disassembly slot within the mounting groove, the telescopic power device includes a linear cylinder, which is fixedly mounted on the mounting platform. The telescopic gripper includes a gripper cylinder and a disassembly chuck, with the disassembly chuck fixedly mounted on the gripper cylinder's claw. The gripper cylinder is fixed to the piston rod of the linear cylinder via a gripper seat. The linear cylinder drives the gripper seat, which in turn moves the gripper cylinder linearly to approach or move away from the aluminum foil pressure ring. This allows for effective clamping via the disassembly chuck, making the operation simple and reliable. Even with the edge suspended, clamping is still convenient and ensures accurate clamping.

[0014] Furthermore, the downward pressure drive device includes a downward pressure base located next to the mounting platform. A column is vertically fixedly installed on the downward pressure base. A guide rod is provided on the column. A lifting and sliding guide sleeve is fitted on the guide rod. A connecting rod is fixedly installed on the guide sleeve. A drive mounting plate is fixedly installed at the free end of the connecting rod. A downward pressure bracket is rotatably installed at the bottom of the drive mounting plate. A contact drive block is provided at the lower part of the downward pressure bracket to contact and press down with the particulate matter sampling head. A drive power device is provided at the upper part of the drive mounting plate to drive the downward pressure bracket to rotate. By manually lifting the guide sleeve and automatically lowering the guide sleeve, the guide sleeve and guide rod can be coordinated to lift and rotate, so that the connected downward pressure bracket can be lifted and deflected. Then, the drive power device drives the downward pressure bracket to rotate, which drives the particulate matter sampling head to rotate through the contact drive block. The movable support platform ensures stable rotation, effectively ensuring that the particulate matter sampling head can rotate stably, and the aluminum foil pressure ring at the edge can be effectively pulled off.

[0015] Furthermore, since the pressure support includes three vertical pressure rods, and the contact drive block is fixedly installed at the bottom of the pressure rod, the contact drive block is made of a material with high friction. The pressure rod is rotatably connected to the drive mounting plate through a connecting seat. The three pressure rods can ensure stable pressure on the particulate matter sampling head while allowing for clearance to rotate and avoid the sampling channel of the particulate matter sampling head, ensuring stable and reliable pressure drive, while facilitating accurate pressure and improving the usage effect.

[0016] Furthermore, since the card box has sliding guides on both sides and outer edges that cooperate with the mounting box, the positioning structure is a positioning baffle. The positioning baffle is fixedly installed on the side of the mounting box to block the card box. The outer edges can provide accurate guidance and limit the upper and lower positions to ensure the stability of the card box. The positioning baffle can ensure that the card box can be accurately locked in place when it slides in.

[0017] Furthermore, since the cutting structure includes a cutting blade, the side wall of the mounting housing is provided with a cutting retraction groove to accommodate the cutting blade, and the cutting retraction groove is located directly above the edge of the mounting groove. The upper end of the cutting blade is hinged and installed in the cutting retraction groove. The cutting retraction groove is provided with a compression spring that is connected to the cutting blade and swings elastically. When the cutting blade is located in the cutting retraction groove, part of the cutting blade remains outside the cutting retraction groove. When the particulate sampling head is vertically inserted into the mounting groove, the edge of the particulate sampling head will squeeze the cutting blade, thereby forcing the cutting blade to retract into the cutting retraction groove. However, the aluminum foil pressure ring will be cut, and the cutting blade being located in the cutting retraction groove ensures that part of the cutting blade will be exposed, ensuring accurate cutting. At the same time, the particulate sampling head can fall into the mounting groove, making the cutting of the aluminum foil pressure ring as convenient as possible and improving the use effect.

[0018] Furthermore, the card box is equipped with a handle for easy pulling, which facilitates the sliding and pulling of the card box and improves the ease of use. Attached Figure Description

A column 13 is vertically fixedly mounted on the downward pressure base 12. A guide rod 14 is provided on the column 13. A lifting and sliding guide sleeve 15 is fitted on the guide rod 14. A connecting rod 16 is fixedly mounted on the guide sleeve 15. A driving mounting plate 17 is fixedly mounted on the free end of the connecting rod 16. A downward pressure bracket is rotatably mounted on the bottom of the driving mounting plate 17. A contact driving block 18 that contacts and presses down with the particulate matter sampling head 7 is provided at the lower part of the downward pressure bracket. A driving power device for driving the downward pressure bracket to rotate is provided at the upper part of the driving mounting plate 17. The driving power device includes... The device includes a drive motor 19, a gear transmission structure 20 on the drive mounting plate 17, and a gear mounting bracket 21 on the drive mounting plate 17. The output shaft of the drive motor 19 passes through the gear mounting bracket 21 and is connected to the gear transmission structure 20. The gear transmission structure 20 drives the lower support bracket to rotate, and the particulate matter sampling head 7 can be driven to rotate by contacting the drive block 18. The movable support platform 6 ensures stable rotation. By manually lifting the guide sleeve 15 and automatically lowering the guide sleeve 15, the guide sleeve 15 and the guide rod 14 can be coordinated to lift and rotate, so that the connected lower support bracket can be lifted and deflected, and the aluminum foil pressure ring at the edge can be effectively pulled off.

[0029] Furthermore, the pressing bracket includes three vertical pressing rods 22, and the contact driving block 18 is fixedly installed at the bottom of the pressing rods 22. The contact driving block 18 is made of a material with high friction. The pressing rods 22 are rotatably connected to the drive mounting plate 17 through the connecting seat 23.

The contact driving block 18 is made of rubber, and the contact surface that contacts the particulate matter sampling head 7 can also be provided with certain textures to increase friction and improve the friction effect.

[0030] like Figure 1 and Figure 2 As shown, the card box 4 has sliding guides on both sides and outer eaves 24 that cooperate with the mounting box 2. The positioning structure is a positioning baffle 25, which is fixedly installed on the side of the mounting box 2 to block the card box 4. The outer eaves 24 can provide accurate guidance and upper and lower limit to ensure the stability of the card box 4. The positioning baffle 25 can ensure that the card box 4 can be accurately locked in place when sliding.

[0031] like Figure 3 and Figure 4As shown, the cutting structure includes a cutting blade 26. A cutting relief groove 27 for accommodating the cutting blade 26 is provided on the side wall of the mounting housing 2, and the cutting relief groove 27 is located directly above the edge of the mounting groove 5. The upper end of the cutting blade 26 is hinged within the cutting relief groove 27. A compression spring 28, connected to the cutting blade 26, elastically swings within the cutting relief groove 27. When the cutting blade 26 is located within the cutting relief groove 27, a portion of the cutting blade 26 remains outside the cutting relief groove 27. The mounting position of the cutting blade 26 is... Positioned directly above the edge of the mounting groove 5, the particulate sampling head 7 is accurately cut by the edge of the mounting groove 5 when it is aligned with and inserted into the groove. The edge of the particulate sampling head 7 will squeeze the cutting blade 26, thereby forcing the cutting blade 26 to retract into the cutting relief groove 27. However, the aluminum foil pressure ring will still be cut, and the cutting blade 26 will be partially exposed within the cutting relief groove 27 to ensure accurate cutting. At the same time, the particulate sampling head 7 can fall into the mounting groove 5, making it as convenient as possible to cut the aluminum foil pressure ring and improving the usage effect.

The swing connecting rod 16 moves the lower pressing rod 22 above the particulate matter sampling head 7, and the contact drive block 18 presses down on the particulate matter sampling head 7. Then, the drive motor 19 drives the gear transmission structure 20 to drive the connecting seat 23 to rotate, thereby causing the lower pressing rod 22 to drive the particulate matter sampling head 7 to rotate. At the same time, the linear cylinder 9 drives the gripper cylinder 10 to extend into the disassembly through groove 8 and clamp the aluminum foil pressure ring through the disassembly chuck 11. Then, the gripper cylinder 10 is driven to retract, which, together with the rotation of the particulate matter sampling head 7, peels off the aluminum foil pressure ring.
