[0002] The SMC workshop liquid powder automatic metering and conveying equipment is an automated equipment specially designed for the sheet molding compound (SMC) production workshop. Its main function is to accurately measure liquid and powder raw materials and automatically convey them to specific production stations or equipment to improve production efficiency, ensure batching accuracy, reduce manual labor intensity and reduce raw material waste.

[0003] During the transportation process, powder materials have a small particle size, which makes them easy to enter the tiny gaps and corners of the equipment. For example, the particle size of some ultrafine powders can reach several microns or even smaller, and can easily penetrate into the seals, joints and other parts of the equipment. Small-particle powders also have a large specific surface area and are easily adsorbed on the surface of the equipment. For example, static electricity can cause powder particles to adsorb on the inner wall of a metal pipe or container, making it difficult to fall off and easy to remain inside the equipment, which will not only affect the next metering accuracy, but may also breed bacteria or cause chemical reactions, affecting product quality. Summary of the invention

[0004] In view of the problem that the powder materials are easily adsorbed on the conveying pipeline due to their small particles, which may breed bacteria or cause chemical reactions, thus affecting product quality, the present invention is proposed.

DETAILED DESCRIPTION

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0028] Example 1

[0029] Reference Figure 1-Figure 6 , which is the first embodiment of the present invention, provides an automatic metering and conveying equipment for liquid powder in an SMC workshop, including a transport pipe body 1, in which a conveying component 2 is rotatably installed. The conveying component 2 is a prior art, and a auger conveying device or other conveying devices can be used. One end of the transport pipe body 1 is fixedly connected and installed with a discharge port 3, and the lower end of the transport pipe body 1 is fixedly installed with a dust collection component 6.

[0030] The purge device comprises an air blowing pipe 41 rotatably installed in the transport pipeline body 1, a plurality of nozzle assemblies 42 are fixedly installed in an equidistant array on the outer circumference of the air blowing pipe 41, a connecting ring 43 is connected and installed at one end of the air blowing pipe 41, a fixing ring 44 is connected and installed at one end of the connecting ring 43, an air pump 45 is fixedly installed at the outer end of the transport pipeline body 1, an output end of the air pump 45 passes through the transport pipeline body 1 and is fixedly connected with one end of the fixing ring 44, a first gear ring 51 is integrally formed and installed at the inner end of the connecting ring 43, the first gear ring 51 is meshed and connected with a first gear 52, a rotating rod 53 is fixedly installed at one end of the first gear 52, and the outer end of the transport pipeline body 1 A first motor 54 is fixedly installed, one end of the rotating rod 53 passes through the transport pipeline body 1 and is fixedly connected to the output end of the first motor 54, and the air pump 45 sprays air into the transport pipeline body 1 through the fixed ring 44, the connecting ring 43, the blowing pipe 41 and multiple nozzle assemblies 42 to blow out the dust infiltrated in the transport pipeline body 1, and then the first motor 54 drives the first gear ring 51 in the connecting ring 43 to mesh and rotate with the first gear 52 through the rotating rod 53, so that the blowing pipe 41 rotates accordingly, so that the blowing pipe 41 can rotate in the transport pipeline body 1, and the interior of the transport pipeline body 1 is cleaned in all aspects to ensure that all the infiltrated dust is blown out.

[0031] The nozzle assembly 42 includes a nozzle pipe 421, which is connected to and fixedly installed on the outer peripheral surface of the blowing pipe 41, and a fixed frame 422 is fixedly installed on one end of the nozzle pipe 421. A rotating plate 423 is rotatably installed in the fixed frame 422, and a plurality of sealing plates 424 are slidably installed on one end of the rotating plate 423. A plurality of sliding grooves 425 are opened on the rotating plate 423, and a sliding rod 426 is slidably installed in the sliding groove 425. One end of the sliding rod 426 is fixedly connected to the corresponding sealing plate 424. The outer peripheral surface of the rotating plate 423 is integrally formed with a second gear ring 427, and one end of the second gear ring 427 is meshedly connected with a second gear 428. A second motor 429 is fixedly installed on one end of the second gear 428. One end of the second motor 429 is fixedly installed on the inner wall of the fixed frame 422, and the second gear 428 is driven by the second motor 429. The second gear ring 427 engaged with the second gear 428 drives the rotating plate 423 to rotate. At this time, the sliding groove 425 on the rotating plate 423 rotates together with the rotating plate 423. At the same time, since the sliding groove 425 is opened in an arc shape, the sliding rod 426 is forced to slide in the sliding groove 425, so that the sliding rod 426 is displaced. The displaced sliding rod drives the sealing plate 424 to rotate, so that the sealing plate 424 is opened. After the sealing plate 424 is opened, the rotating plate 423 is reversed, the sliding rod 426 is reset, and the sealing plate 424 is closed again. Therefore, the forward and reverse rotation of the rotating plate 423 can realize the closing or opening of the nozzle pipe 421, which ensures that the nozzle assembly 42 works in the transport pipeline body 1 so that the powder material will not block the nozzle pipe 421, and ensures the normal working efficiency of the nozzle pipe 421 when purging the inside of the transport pipeline body 1.

[0032] Example 2

[0033] Reference Figure 1-Figure 6 , which is the second embodiment of the present invention, and this embodiment is different from the first embodiment in that:

[0034] One end of the dust collection component 6 is connected to a connecting pipe 7, one end of the connecting pipe 7 is fixedly connected to the discharge port 3, a control valve 8 is fixedly installed on the connecting pipe 7, the dust collection component 6 includes a dust collection box 61, the dust collection box 61 is fixedly installed at the lower end of the transport pipeline body 1, a plurality of filter screens 62 are arranged in sequence in the dust collection box 61, the mesh diameters of the filter screens 62 are reduced in sequence, the dust can be graded and filtered to improve the filtering effect, one end of the dust collection box 61 is connected to a dust collector 63, the dust collector 63 is mainly composed of a motor, a fan and a circuit component, and its working principle is relatively simple and efficient. The following is the detailed working principle of the dust collector 63:

[0035] The motor of the vacuum cleaner 63 drives the fan to rotate at a high speed, sucking air from the suction port of the vacuum cleaner 63, so that a certain vacuum is generated in the dust box 61. As the air in the dust box 61 is discharged, a higher pressure difference is formed with the outside world. Under the action of the pressure difference, the dust near the discharge port 3 is sucked into the dust box 61 along with the air, and the dust is filtered through multiple filters 62 and retained in the dust box 61. The air discharged by the motor is discharged from the vacuum cleaner 63 through the air outlet.

[0036] A collecting box 64 is installed at the lower end of the filter 62 in abutment with it, and a plurality of baffles are fixedly installed in the collecting box 64. The lower end of the filter 62 at the upper end of the baffle is in abutment with it, so that a plurality of collecting cavities are formed inside the collecting box 64 to collect the dust dropped after being filtered by the corresponding filter 62. The collecting box 64 is installed in the dust box 61 by sliding. A box door is hinged at one end of the dust box 61. The collecting box 64 can be taken out by opening the box door. At the same time, the filter 62 can be disassembled and taken out in turn through the box door for cleaning. By starting the vacuum cleaner 63, the dust blown out is sucked into the dust box 61 through the discharge port 3 and the connecting pipe 7 in turn, and the dust is filtered in turn by the plurality of filter screens 62 and drops into the collecting box 64. At the same time, the collecting box 64 at the lower end of the filter 62 can be slidably arranged to facilitate the cleaning and recycling of the collected dust.

[0037] The remaining structures are the same as those of Example 1.

[0038] The specific operation working principle of the present invention is as follows:

[0039] When the transport work of the transport pipeline body 1 is completed, the air pump 45 is started. The air pump 45 conveys the gas to the connecting ring 43 connected to the fixing ring 44 through the connected fixing ring 44, and then conveys the gas from the connecting ring 43 to the blowing pipe 41 connected to the connecting ring 43, and then conveys the gas from the blowing pipe 41 to the connected multiple nozzle assemblies 42. Then, the second motor 429 is started to make the second motor 429 drive the fixedly connected second gear 428 to rotate. The second gear 428 drives the rotating plate 423 to rotate through the meshing second gear ring 427. The rotation of the rotating plate 423 drives the sliding rod 426 in the sliding groove 425 opened on the rotating plate 423 to slide in the sliding groove 425. At the same time, the sliding rod 426 drives the fixedly connected sealing plate 424 to slide in the fixed frame 422, so that the conflicting ends of the sealing plate 424 are separated, so that the nozzle pipe 421 is in an open state, and then the gas is blown to the inside of the transport pipeline body 1 through the nozzle pipe 421.

[0040] Next, start the first motor 54, so that the first motor 54 drives the first gear 52 fixedly connected to the other end of the rotating rod 53 to rotate through the fixedly connected rotating rod 53, the first gear 52 drives the connecting ring 43 to rotate through the meshing first gear ring 51, and the connecting ring 43 drives the blowing pipe 41 to rotate, so that the nozzle assembly 42 comprehensively blows the inside of the transport pipeline body 1 to blow out all the infiltrated dust.

[0041] Next, start the control valve 8 to connect the dust box 61 with the discharge port 3 through the connecting pipe 7, then start the vacuum cleaner 63 to discharge the purged dust into the dust box 61 through the discharge port 3, and then filter the dust step by step through multiple filter screens 62 with gradually decreasing pore sizes in the dust box 61. The filtered dust falls into the collection box 64 and accumulates. Finally, the accumulated dust is cleaned and recovered.

[0042] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
