Description

Technical Field

[0001] The invention relates to the technical field of varnish production equipment, in particular to a polyester resin varnish sampling device. Background Art

[0002] Polyester resin is a general term for polymer compounds formed by polycondensation of diols or dibasic acids or polyols and polyacids. Polyester resins are divided into saturated polyester resins and unsaturated polyester resins. Unsaturated polyester adhesives are mainly composed of unsaturated polyester resins, pigments, fillers, initiators and other additives. The adhesive has low viscosity, is easy to wet, and has good processability. The cured adhesive layer has high hardness, good transparency, high brightness, can be quickly cured under pressure at room temperature, has good heat resistance, and excellent electrical properties. It is mainly used for bonding fiberglass, hard plastics, concrete, electrical cans, etc. Varnish, also known as varnish, is a coating composed of resin as the main film-forming substance and solvent. Since both the coating and the coating film are transparent, it is also called transparent coating. It is applied to the surface of an object and forms a smooth film after drying, showing the original texture of the surface. Therefore, varnish using polyester resin is widely used.

[0003] The existing polyester resin varnish is often directly discharged outward through a sampling tube connected to the tank body during sampling, and then transferred to the detection equipment for testing. However, a certain amount of varnish will remain in the tube after each sampling, which requires manual cleaning. If it is not cleaned thoroughly, it will affect the accuracy of the next test, which is relatively cumbersome. At the same time, sampling close to the outside of the tank body also has the problem of uneven mixing of the varnish leading to quality differences, and the problem of inability to achieve fully automatic sampling, testing and sample retention. Summary of the invention

[0004] The present invention aims to solve one of the technical problems existing in the prior art or related technology.

[0005] To this end, the technical solution adopted in the present invention is:

[0006] A polyester resin varnish sampling device comprises: a reaction tank body and an operating mechanism; the operating mechanism is arranged on the reaction tank body; the operating mechanism comprises a sampling assembly installed on the reaction tank body, a material mixing assembly installed on the sampling assembly, a cleaning assembly arranged on the sampling assembly and a detection assembly arranged below the sampling assembly; the sampling assembly comprises a sampling tube installed on the reaction tank body, a mounting frame fixed to the end of the sampling tube, an electric telescopic rod installed on the mounting frame, a connecting rod fixed to the driving end of the electric telescopic rod and located in the sampling tube, a sealing column and a sealing plug respectively arranged at both ends of the connecting rod and a sample discharge tube connected to the bottom of the sampling tube.

[0008] In a preferred example, the present invention can be further configured as follows: a guide frame is installed on the side of the filter plate, a receiving groove for receiving the stirring rod is opened on the guide frame, and a guide rod is provided at the end of the guide frame.

[0009] In a preferred example, the present invention can be further configured as follows: the guide rod is a strip structure that is arranged obliquely inward.

[0010] In a preferred example, the present invention can be further configured as follows: the cleaning component includes a cleaning tube connected to the sampling tube, a water pump connected to the end of the cleaning tube, a water tank connected to the water pump, a hot air blower arranged under the water tank, an air duct connected between the hot air blower and the cleaning tube, a control valve 1 arranged on the air duct, and a control valve 2 installed on the cleaning tube.

[0015] 1. The present invention uses a sampling component and a detection component, and can use an electric telescopic rod to drive the sealing plug to move in the sampling tube, so that the varnish in the reaction tank body gradually enters the sampling tube. When the sealing plug passes over the sample tube, the varnish will enter the sample tube and then fall into the sample retention groove. At this time, the sealing plug is reset to complete the sampling. Then the second motor drives the turntable to rotate, and the varnish is transferred to the bottom of the detection probe for detection.

[0027] To make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in combination with specific implementations and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0028] It is to be understood that these descriptions are exemplary only and are not intended to limit the scope of the invention.

[0029] A polyester resin varnish sampling device provided by some embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0030] Combination Figures 1 to 4 As shown, a polyester resin varnish sampling device provided by the present invention comprises: a reaction tank body 100 and an operating mechanism 200;

[0031] The operating mechanism 200 is arranged on the reaction tank body 100; the operating mechanism 200 includes a sampling component installed on the reaction tank body 100, a material mixing component installed on the sampling component, a cleaning component arranged on the sampling component and a detection component arranged below the sampling component.

[0032] Among them, the sampling assembly includes a sampling tube 210 installed on the reaction tank body 100, a mounting bracket 220 fixed to the end of the sampling tube 210, an electric telescopic rod 230 installed on the mounting bracket 220, a connecting rod 240 fixed to the driving end of the electric telescopic rod 230 and located in the sampling tube 210, a sealing column 250 and a sealing plug 260 respectively arranged at both ends of the connecting rod 240, and a sample discharge tube 270 connected to the bottom of the sampling tube 210. The sealing column 250 can ensure the sealing of the sampling tube 210 during cleaning, and can be moved out under the drive of the electric telescopic rod 230 during sampling.

[0033] Furthermore, the detection assembly includes a fixed box 510 installed on the reaction tank body 100 and located outside the sample row tube 270, a motor 2 520 installed in the fixed box 510, a turntable 530 fixed to the driving end of the motor 2 520, a sample retention groove 540 opened on the turntable 530 and corresponding to the sample row tube 270, a through hole 550 arranged between the sample retention grooves 540 and passing through the sample row tube 270, a detector 560 installed on the fixed box 510, a lifting rod 570 fixed to the bottom of the detector 560, a detection probe 580 connected to the bottom of the lifting rod 570 and a waste water tank 590 installed at the bottom of the fixed box 510.

[0034] Specifically, through the sampling component and the detection component, the electric telescopic rod 230 can be used to drive the sealing plug 260 to move in the sampling tube 210, so that the varnish in the reaction tank body 100 gradually enters the sampling tube 210. When the sealing plug 260 passes over the sample discharge tube 270, the varnish will enter the sample discharge tube 270 and then fall into the sample retention groove 540. At this time, the sealing plug 260 is reset to complete the sampling. Then the motor 2 520 drives the turntable 530 to rotate, and the varnish is transferred to the bottom of the detection probe 580 for detection. At this time, the through hole 550 rotates to the position of the sample discharge tube 270, and the excess varnish can be directly discharged to the waste water tank 590, thereby realizing automatic sampling and detection.

[0035] Furthermore, the material mixing assembly includes a motor 310 fixed between the electric telescopic rod 230 and the connecting rod 240, a limit frame 320 installed on the motor 310 and clamped in the mounting frame 220, a fixing rod 330 fixed to the middle of the sealing plug 260, a filter plate 340 connected to the end of the fixing rod 330, a torsion spring shaft 350 installed on the side of the filter plate 340 and a stirring rod 360 fixed on the torsion spring shaft 350. The material mixing assembly can use the sealing column 250 to drive the filter plate 340 and the stirring rod 360 to rotate, so as to further stir the varnish around the sampling port of the sampling tube 210, prevent uneven mixing caused by wall adhesion, and improve the sampling accuracy. When the electric telescopic rod 230 is extended or retracted, the limit frame 320 can be clamped in the mounting frame 220 to keep the motor 310 moving horizontally, which is more reasonable.

[0036] It should be noted that a guide frame 370 is installed on the side of the filter plate 340, and a storage groove 380 for accommodating the stirring rod 360 is opened on the guide frame 370, and a guide rod 390 is provided at the end of the guide frame 370. The guide rod 390 can play a guiding role to facilitate the entry of the storage groove 380. After entering the sampling tube 210, the stirring rod 360 is squeezed into the storage groove 380, and the filter plate 340 can filter the sampled varnish to improve the sampling accuracy.

[0037] Furthermore, the guide rod 390 is a strip-shaped structure that is tilted inwardly, so as to facilitate the filter plate 340 to enter the sampling tube 210 .

[0038] On the other hand, the cleaning component includes a cleaning tube 410 connected to the sampling tube 210, a water pump 420 connected to the end of the cleaning tube 410, a water tank 430 connected to the water pump 420, a hot air blower 440 arranged below the water tank 430, an air duct 450 connected between the hot air blower 440 and the cleaning tube 410, a control valve 1 460 arranged on the air duct 450, and a control valve 2 470 installed on the cleaning tube 410. After the sealing plug 260 is reset, the water pump 420 draws clean water in the water tank 430 and injects it into the sampling tube 210 along the cleaning tube 410 to flush the varnish remaining in the sampling tube 210. After flushing, the waste water is discharged into the waste water tank 590 along the sample discharge tube 270, and then the hot air generated by the hot air blower 440 enters the sampling tube 210 and the sample discharge tube 270 to dry the inside of the tube to ensure the accuracy of the next sampling and detection, which is more practical.

[0039] Specifically, a sealing gasket 531 is fixed to the top surface of the turntable 530, which can improve the sealing between the turntable 530 and the fixed box 510, prevent the varnish from flowing through the cells, and provide a higher controllability of the varnish.

[0040] Furthermore, a sealing ring 261 is provided in the middle of the sealing plug 260 to improve the sealing performance of the sealing plug 260 in the sampling tube 210 and prevent leakage of varnish.

[0041] The working principle and use process of the present invention are as follows: when sampling is required, first, the motor 310 drives the fixed rod 330 connected to the end of the connecting rod 240 to rotate, thereby driving the filter plate 340 and the stirring rod 360 to rotate, stirring and mixing the varnish at the entrance of the sampling tube 210 to improve uniformity, and then the electric telescopic rod 230 drives the sealing plug 260 to move outward in the sampling tube 210. At this time, the varnish in the reaction tank body 100 slowly enters the sampling tube 210. When the sealing plug 260 exceeds the sample discharge tube 270, the varnish flows into the sample discharge tube 270. When the varnish flows into the sample retention groove 540, the electric telescopic rod 230 drives the sealing plug 260 to move. After the position of the sampling tube 410 is reset, the motor 2 520 drives the turntable 530 to rotate, and the varnish is transferred to the bottom of the detection probe 580 for detection. At this time, the through hole 550 rotates to the position of the sample discharge tube 270, and the excess varnish can be directly discharged into the waste water tank 590 through the through hole 550. After the sampling is completed, the water pump 420 draws the clean water in the water tank 430 and injects it into the sampling tube 210 along the cleaning tube 410 to rinse the residual varnish in the sampling tube 210. After rinsing, the waste water is discharged into the waste water tank 590 along the sample discharge tube 270, and then the hot air generated by the hot air blower 440 enters the sampling tube 210 and the sample discharge tube 270 to dry the inside of the tube.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the claims and their equivalents.
