[0015] The present invention has the following beneficial effects:

[0016] (1) An unsaturated polyester resin material sampling device of the present invention. When the intelligent sensing motor is started, the intelligent sensing motor drives the rotation of the rotating shaft, the rotating shaft drives the rotation of several centrifugal fan blades, the centrifugal fan blades generate suction force, and the suction force is sucked into the circular sampling box through the ventilation groove, and then sucked into the sampling tube through the ventilation holes and the holes on the heating belt perforated plate. The suction force sucks the unsaturated polyester resin from the storage tank into the circular sampling box. During this process, the rotation of the rotating shaft drives the rotation of the connecting plate, the connecting plate drives the rotation of the circular sampling box, and the circular sampling box drives the rotation of several sampling tubes. During the rotation of the sampling tubes, the unsaturated polyester resin in the storage tank is stirred, and the stirring improves the fluidity of the unsaturated polyester resin, which can effectively avoid the blockage of the polyester resin and improve the fluidity of the polyester resin;

[0017] (2) An unsaturated polyester resin material sampling device of the present invention. When in use, several sampling tubes are inserted into several cylinders, the sampling tubes drive the circular sampling box to descend, the circular sampling box drives the centrifugal air box to descend, the centrifugal air box drives the C-shaped plate to descend, the C-shaped plate drives the L-shaped plate to descend, and the L-shaped plate drives the two card slots to descend. When the card slots contact the annular cover, they move away from each other. At this time, the two fixing springs undergo compressive deformation. When the card slots move to the position of the trapezoidal block, the card slots are snapped into the trapezoidal block under the elastic force of the fixing springs. Since the intelligent sensing motor and the C-shaped plate are fixed, the intelligent sensing motor is also fixed at this time, and the sampling device is fixed on the annular cover at this time;

[0018] (3) An unsaturated polyester resin material sampling device of the present invention. After the polyester resin enters the circular sampling box, the polyester resin drives the heating belt perforated plate to rise, the heating belt perforated plate drives the circular sliding rod to rise, the circular sliding rod drives the movable ring to rise, the movable ring drives the rectangular plate to rise, the rectangular plate drives the movable rod to rise, the movable rod drives the strip plate to move away from the circular sampling box, the strip plate drives the closing block to move. When the top of the movable ring contacts the L-shaped plate, the corresponding closing block blocks the hole connecting the circular sampling box and the sampling tube. At this time, since the circular sampling box is in a sealed state, the load of the intelligent sensing motor increases, which may cause the current to exceed the normal range. At this time, the intelligent sensing motor will automatically shut down, avoiding damage caused by the large load of the intelligent sensing motor, and at the same time preventing the polyester resin in the circular sampling box from flowing back into the storage tank;

[0019] (4) The present invention provides an unsaturated polyester resin material sampling device. After extracting the polyester resin, the two T-shaped round rods are pulled apart to remove the circular sampling box. The unsaturated polyester resin in the circular sampling box will be continuously heated by the heated perforated filter plate, which effectively prevents the unsaturated polyester resin from cooling and solidifying. After the sampling tube leaves the rotating plate, the sealing trapezoidal block will be pushed by the elastic force of the sealing spring to move toward the center of the rotating plate until the sealing trapezoidal block contacts the inner wall of the sealing groove near the center of gravity of the rotating plate. At this time, the sealing trapezoidal block closes the hole for inserting the sampling tube, so that the storage box is in a sealed state, which effectively prevents air from entering the storage box and causing the unsaturated polyester resin in the storage box to solidify, thereby affecting the next sampling work.

[0020] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] As Figure 3As shown, a centrifugal air box 507 is rotatably installed at the top of the circular sampling box 505. An intelligent sensing motor 508 is fixedly installed at the top of the centrifugal air box 507. A rotating shaft 509 is fixedly installed on the output shaft of the intelligent sensing motor 508.

A plurality of centrifugal fan blades 510 are fixedly installed on the rotating shaft 509.

[0036] The intelligent sensing motor 508 drives the rotating shaft 509 to rotate, the rotating shaft 509 drives a plurality of centrifugal fan blades 510 to rotate, the centrifugal fan blades 510 generate a suction force, and the suction force sucks into the circular sampling box 505 through the ventilation slots 511.

[0037] As Figure 3 shown, a plurality of ventilation slots 511 are opened on the bottom inner wall of the centrifugal air box 507. The bottom ends of the plurality of ventilation slots 511 all penetrate the circular sampling box 505. A connecting plate 512 is fixedly installed in the circular sampling box 505.

[0039] As Figure 4 and Figure 5 shown, a fixing mechanism 6 is arranged on the centrifugal air box 507. The fixing mechanism 6 includes a U-shaped plate 601 fixedly installed at the top of the centrifugal air box 507. The U-shaped plate 601 is fixedly connected to the intelligent sensing motor 508. L-shaped plates 602 are respectively fixedly installed on the left outer wall and the right outer wall of the U-shaped plate 601. Rectangular grooves 603 are respectively opened on one side of the two L-shaped plates 602 close to each other. T-shaped round rods 604 are respectively slidably installed on the inner walls of the two rectangular grooves 603 away from each other. Clamping grooves 605 are respectively fixedly installed at one ends of the two T-shaped round rods 604 close to each other. Two trapezoidal clamping blocks 606 are opened on the outer wall of the annular cover 2. One ends of the two clamping grooves 605 close to each other respectively extend into the two trapezoidal clamping blocks 606 and are respectively slidably connected to the two clamping grooves 605. Fixing springs 607 are respectively sleeved on the two T-shaped round rods 604. One ends of the two fixing springs 607 close to each other are respectively fixedly connected to the two clamping grooves 605. One ends of the two fixing springs 607 away from each other are respectively fixedly connected to the two rectangular grooves 603.

[0040] The centrifugal air box 507 drives the U-shaped plate 601 to descend. The U-shaped plate 601 drives the L-shaped plate 602 to descend. The L-shaped plate 602 drives the two clamping grooves 605 to descend. When the clamping grooves 605 contact the annular cover 2, they move away from each other. At this time, the two fixing springs 607 undergo compressive deformation. When the clamping grooves 605 move to the position of the trapezoidal clamping block 606, the clamping grooves 605 are snapped into the trapezoidal clamping block 606 under the elastic force of the fixing springs 607. Since the intelligent sensing motor 508 is fixed to the U-shaped plate 601, the intelligent sensing motor 508 is also fixed at this time.

[0041] As Figure 3 shown, an activity mechanism 7 is arranged in the circular sampling box 505. The activity mechanism 7 includes a heating perforated filter plate 701 slidably installed in the circular sampling box 505. Two circular sliding rods 702 are fixedly installed at the top of the heating perforated filter plate 701. The tops of the two circular sliding rods 702 both extend outside the circular sampling box 505 and are both slidably connected to the circular sampling box 505. An activity ring 703 is fixedly sleeved on the two circular sliding rods 702.

[0042] The polyester resin drives the heating perforated filter plate 701 to rise. The heating perforated filter plate 701 drives the circular sliding rods 702 to rise. The circular sliding rods 702 drive the activity ring 703 to rise.

[0043] As Figure 7 shown, a rectangular plate 704 is fixedly installed at the bottom of the activity ring 703. The bottom ends of several rectangular plates 704 are respectively hinged with activity rods 705. Several rectangular sliding grooves 706 are formed in the circular sampling box 505.

[0044] The activity ring 703 drives the rectangular plate 704 to rise. The rectangular plate 704 drives the activity rod 705 to rise. The activity rod 705 drives the strip-shaped plate 708 to move away from the circular sampling box 505.

[0045] As Figure 6 shown, several closing blocks 707 are respectively slidably installed in several rectangular sliding grooves 706. Strip-shaped plates 708 are fixedly installed at the mutually remote ends of several closing blocks 707. The mutually remote ends of several strip-shaped plates 708 respectively extend outside several rectangular sliding grooves 706. Several strip-shaped plates 708 are respectively hinged with several activity rods 705.

[0046] The strip plate 708 will drive the closing block 707 to move. When the top of the movable ring 703 contacts the L-shaped plate 602, the corresponding closing block 707 blocks the hole connecting the circular sampling box 505 and the sampling tube 506. At this time, since the circular sampling box 505 is in a sealed state, the load of the intelligent sensor motor 508 will increase, which may cause the current to exceed the normal range. At this time, the intelligent sensor motor 508 will automatically shut down to avoid damage to the intelligent sensor motor 508 due to a large load, and at the same time prevent the polyester resin in the circular sampling box 505 from flowing back into the storage box 1.

[0047] like Figure 8 As shown, a plurality of sealing mechanisms 8 are provided on the rotating plate 3 , and a sealing groove 801 is opened on the sealing mechanism 8 , a sealing spring 802 is fixedly installed in the sealing groove 801 , and a sealing trapezoidal block 803 is fixedly installed at the right end of the sealing spring 802 .

[0048] After the sampling tube 506 leaves the rotating plate 3, the sealing trapezoidal block 803 will be pushed by the elastic force of the sealing spring 802 to move toward the center of the rotating plate 3 until the sealing trapezoidal block 803 contacts the inner wall of the sealing groove 801 near the center of gravity of the rotating plate 3. At this time, the sealing trapezoidal block 803 closes the hole into which the sampling tube 506 is inserted, so that the storage box 1 is in a sealed state, effectively preventing air from entering the storage box 1 and causing the unsaturated polyester resin in the storage box 1 to become solid, thereby affecting the next sampling work.

[0049] In use, several sampling tubes 506 are inserted into several cylinders 504. The sampling tubes 506 will drive the circular sampling box 505 to descend. The circular sampling box 505 will drive the centrifugal air box 507 to descend. The centrifugal air box 507 will drive the C-shaped plate 601 to descend. The C-shaped plate 601 drives the L-shaped plate 602 to descend. The L-shaped plate 602 will drive two card slots 605 to descend. When the card slots 605 come into contact with the annular cover 2, they will move away from each other. At this time, two fixing springs 607 undergo compressive deformation. When the card slots 605 move to the position of the trapezoidal clamping block 606, the card slots 605 will be snapped into the trapezoidal clamping block 606 under the elastic force of the fixing springs 607. Since the intelligent sensing motor 508 and the C-shaped plate 601 are fixed, the intelligent sensing motor 508 will also be fixed at this time. Start the intelligent sensing motor 508. The intelligent sensing motor 508 will drive the rotating shaft 509 to rotate. The rotating shaft 509 drives several centrifugal fan blades 510 to rotate. The centrifugal fan blades 510 will generate a suction force. The suction force will be sucked into the circular sampling box 505 through the ventilation groove 511, and then sucked into the sampling tube 506 through the ventilation hole 513 and the holes on the heating belt hole filter plate 701. The suction force will suck the unsaturated polyester resin from the storage tank 1 into the circular sampling box 505. During this process, the rotation of the rotating shaft 509 will drive the connecting plate 512 to rotate. The connecting plate 512 will drive the circular sampling box 505 to rotate. The circular sampling box 505 drives several sampling tubes 506 to rotate. The sampling tubes 506 will stir the unsaturated polyester resin in the storage tank 1 during rotation, and the stirring will improve the fluidity of the unsaturated polyester resin;

[0050] After the polyester resin enters the circular sampling box 505, the polyester resin will drive the heated perforated filter plate 701 to rise, the heated perforated filter plate 701 will drive the circular slide bar 702 to rise, the circular slide bar 702 will drive the movable ring 703 to rise, the movable ring 703 will drive the rectangular plate 704 to rise, the rectangular plate 704 will drive the movable rod 705 to rise, the movable rod 705 will drive the strip plate 708 to move away from the circular sampling box 505, the strip plate 708 will drive the closing block 707 to move, and when the top of the movable ring 703 contacts the L-shaped plate 602, the corresponding closing block 707 blocks the hole connecting the circular sampling box 505 and the sampling tube 506. At this time, since the circular sampling box 505 is in a sealed state, the load of the intelligent sensor motor 508 will Increase, which may cause the current to exceed the normal range. At this time, the intelligent sensor motor 508 will automatically shut down; after extracting the polyester resin, pull open the two T-shaped round rods 604 to remove the circular sampling box 505, and the unsaturated polyester resin will be continuously heated by the heated perforated filter plate 701 in the circular sampling box 505, which effectively prevents the unsaturated polyester resin from cooling and solidifying. After the sampling tube 506 leaves the rotating plate 3, the sealing trapezoidal block 803 will push the sealing trapezoidal block 803 to move toward the center of the rotating plate 3 under the elastic force of the sealing spring 802, until the sealing trapezoidal block 803 contacts the inner wall of the sealing groove 801 near the center of gravity of the rotating plate 3. At this time, the sealing trapezoidal block 803 closes the hole into which the sampling tube 506 is inserted, so that the storage box 1 is in a sealed state.
