The application of raw material screening devices in candle production not only improves the efficiency and accuracy of raw material screening, but also plays a key role in ensuring the quality of candle products.

[0003] Since the methods of traditional raw material screening devices for candle production mostly rely on manual operation, the efficiency is low and errors are prone to occur. Therefore, those skilled in the art have provided a raw material screening device for candle production to solve the problems raised in the above background art. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the disadvantages existing in the prior art, and a raw material screening device for candle production is proposed. By arranging sieve meshes with three different mesh sizes in the screening frames arranged vertically, and driving the screening frames to vibrate through a vibrator to achieve hierarchical screening, while miniaturizing the device, the screening efficiency is improved, and it is convenient to disassemble and install the screening frames and sieve meshes, and it is convenient to replace sieve meshes with different specifications to meet different screening requirements. By generating suction with a suction pump, the material is sucked into the interior of the box body in sequence through a feed hopper, a suction pipe and a connecting pipe, and through the cooperation of an electric telescopic rod and a blocking structure, automatic discharging of the screened raw materials is realized. This design reduces the need for manual operation, improves production efficiency and safety. By arranging adsorption cotton, activated carbon and a filter screen, when the fan is started to inhale the dust-containing air for multi-layer filtration, the advantages of each filtration layer are fully utilized, and the dust removal and purification effect and the overall performance are improved.

[0005] To achieve the above object, the utility model provides the following technical solution: A raw material screening device for candle production, including a box body, four support legs are arranged in a rectangular array on the lower end surface of the box body, a control panel is arranged at the lower center of the front end surface of the box body, a screening structure is arranged at the upper center of the interior of the box body, four dust removal and purification structures are arranged in a rectangular array on the upper end surface of the box body, a blocking structure is arranged at the center of one side wall of the box body, a guide plate is arranged at the lower center of the interior of the box body, a feeding structure is arranged at the center of the upper end surface of the box body, and a discharge port is arranged at the lower center of one side wall of the box body;

[0006] Through the above technical solution, by adopting sieve meshes with three different mesh sizes arranged in the screening frames arranged vertically, and driving the screening frames to vibrate through a vibrator to achieve grading screening, the device is miniaturized while improving the screening efficiency, and it is convenient to disassemble and install the screening frames and sieve meshes, facilitating the replacement of sieve meshes of different specifications to meet different screening requirements. By generating suction with a suction pump, the material is sucked into the interior of the box body from the material placement box through the suction pipe and the connecting pipe in sequence, and through the cooperation of the electric telescopic rod and the blocking structure, automatic discharging of the raw materials after screening is realized. This design reduces the need for manual operation, improving production efficiency and safety. By setting adsorption cotton, activated carbon, and a filter screen, when the fan is started to inhale the dust-containing air for multi-layer filtration, giving full play to the advantages of each filtration layer, the dust removal and purification effect and the overall performance are improved.

[0007] Further, the screening structure includes three screening frames, three sieve meshes, and multiple vibrators. The three screening frames are respectively arranged vertically at the upper center inside the box body. The three sieve meshes are respectively arranged at the lower center inside the three screening frames. Multiple vibrators are horizontally arranged in a group, and three groups of vibrators are respectively arranged vertically at the upper center of the rear end face of the box body. The output ends of the three groups of vibrators sequentially penetrate the rear end face of the box body and lead to the inside of the three screening frames through the rear end faces of the three screening frames;

[0008] Through the above technical solution, when starting the device for raw material screening, the three groups of vibrators work simultaneously. The output ends of the vibrators drive the screening frames to vibrate. Since the sieve meshes are arranged at the lower center inside the screening frames, the raw materials fall on the sieve meshes. Under the action of vibration, the smaller particle raw materials can fall downward through the sieve meshes, while the larger particle raw materials remain on the sieve meshes. The sieve meshes on the three screening frames have different mesh sizes, so as to achieve grading screening of the raw materials, making the overall device more miniaturized and efficient.

[0009] Further, the dust removal and purification structure includes an exhaust frame, a filter screen, activated carbon, adsorption cotton, and a fan. The exhaust frame is arranged on the upper end face of the box body. The filter screen is arranged at the upper center inside the exhaust frame. The filter screen is arranged inside the exhaust frame at the lower end of the exhaust frame. The activated carbon is arranged inside the exhaust frame at the lower end of the filter screen. The adsorption cotton is arranged inside the exhaust frame at the lower end of the activated carbon. The fan is arranged inside the exhaust frame at the lower end of the adsorption cotton;

[0010] Through the above technical solution, during the process of screening raw materials, the fan starts to generate suction, and the air with dust in the box body is sucked into the exhaust rack. First, it passes through the adsorption cotton, which adsorbs tiny particles and some harmful substances in the air. Then the air passes through the activated carbon, which adsorbs harmful gases and odors in the air. Finally, it passes through the filter screen, which blocks larger particles and impurities. After this series of treatments, the relatively clean air is discharged from the exhaust rack, which can give full play to the advantages of each filter layer and improve the overall performance and efficiency of the dust removal and purification structure.

[0011] Furthermore, the blocking structure includes a connecting plate, two electric telescopic rods, two connecting blocks, a blocking block, a stabilizing frame and a collection box. The connecting plate is arranged at the upper center of one side wall of the box body. The two electric telescopic rods are respectively arranged at the front and rear of the center of the lower end face of the connecting plate. The two connecting blocks are respectively arranged on the output ends of the two electric telescopic rods. The blocking block is arranged on the lower end faces of the two connecting blocks. The stabilizing frame is arranged on one side wall of the blocking block on the lower end faces of the two connecting blocks. The collection box is arranged at the lower center of one side of the box body.

[0012] Through the above technical solution, when discharging the screened raw materials, the electric telescopic rods receive instructions and start to extend. The extension of the electric telescopic rods pushes the connecting blocks to rise, thereby driving the blocking block to move upward. After the blocking block moves upward, the discharge port originally blocked by the blocking block is opened, and the screened raw materials can pass through the discharge port. Since the collection box is placed at a suitable position below the discharge port, the discharged raw materials can smoothly fall into the collection box, realizing orderly collection.

[0013] Furthermore, the feeding structure includes a connecting pipe, a material suction pipe, two flanges, four bolts, a material suction pump and a material placement box. The connecting pipe is arranged at the center of the upper end face of the box body. The material suction pipe is arranged on the upper end face of the connecting pipe. The two flanges are respectively arranged at one end of the connecting pipe and the material suction pipe. The four bolts are arranged in a circular array on the upper end face of the upper flange. The material placement box is arranged at the lower center of one side of the box body. The material suction pump is arranged at the center of the lower inner wall of the material placement box. One end of the material suction pipe is fixedly connected to the output end of the material suction pump.

[0014] Through the above technical solution, when performing the feeding operation, the material suction pump is started. The material suction pump generates suction, so that the materials in the material placement box are sucked in. The materials pass through the output end of the material suction pump, the material suction pipe and the connecting pipe in sequence, and finally enter the interior of the box body. The connecting pipe and the material suction pipe are connected by two flanges and fixed with four bolts to ensure a tight connection and prevent material leakage.

[0015] Furthermore, one end of the four bolts sequentially penetrates the upper end face and the lower end face of the upper flange and extends into the lower flange, and the ends are all threadedly connected inside the lower flange.

[0016] Through the above technical solution, the threaded connection method provides a strong and stable connection force, which can withstand the pressure and vibration during the feeding process, preventing the interface from loosening and material leakage.

[0017] Furthermore, the three screening frames are respectively slidably connected to the center inside the box body, and the three sieve meshes are respectively slidably connected inside the three screening frames;

[0018] Through the above technical solution, it is convenient to disassemble and install the screening frames and sieve meshes, and it is convenient to replace sieve meshes of different specifications to meet different screening requirements.

[0019] Furthermore, the blocking block and the discharge port are mutually adapted;

[0020] Through the above technical solution, the mutually adapted design ensures the tightness of the block, effectively preventing material leakage when discharging is not required.

[0021] The utility model has the following beneficial effects:

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0032] Refer to Figures 1-4 , an embodiment provided by the present utility model: A raw material screening device for candle production, including a box body 1, four support legs 2 are arranged in a rectangular array on the lower end surface of the box body 1, a control panel 3 is arranged at the lower center of the front end surface of the box body 1, a screening structure 4 is arranged at the upper center inside the box body 1, four dust removal and purification structures 5 are arranged in a rectangular array on the upper end surface of the box body 1, a blocking structure 6 is arranged at the center of one side wall of the box body 1, a guide plate 8 is arranged at the lower center inside the box body 1, a feeding structure 7 is arranged at the center of the upper end surface of the box body 1, and a discharge port 9 is arranged at the lower center of one side wall of the box body 1. During the candle production process, the raw materials enter the inside of the box body 1 through the feeding structure 7. After entering the box body 1, the raw materials fall on the screening structure 4. The screening structure 4 screens the raw materials, separates the qualified raw materials from the unqualified impurities. During the screening process, the generated dust is discharged and purified through the dust removal and purification structure 5 to keep the working environment clean.

When it is necessary to discharge the screened raw materials, the blocking structure 6 opens the discharge port 9, and the raw materials are discharged from the discharge port 9. The whole process is controlled and adjusted through the control panel 3.

[0033] The screening structure 4 includes three screening frames 401, three sieve meshes 402 and multiple vibrators 403.

The output ends of the three groups of vibrators 403 sequentially penetrate the rear end face of the box body 1 and reach the inside of the three screening frames 401 through the rear end faces of the three screening frames 401. When starting the device for raw material screening, the three groups of vibrators 403 work simultaneously. The output ends of the vibrators 403 drive the screening frames 401 to vibrate. Since the sieve mesh 402 is arranged at the lower center inside the screening frame 401, the raw materials fall on the sieve mesh 402. Under the action of vibration, the smaller particle raw materials can pass through the sieve mesh 402 and fall downward, while the larger particle raw materials remain on the sieve mesh 402. The mesh sizes of the sieve meshes 402 on the three screening frames 401 are different, so as to realize the grading screening of the raw materials, making the whole device more miniaturized and efficient. The three screening frames 401 are respectively slidably connected to the center inside the box body 1, and the three sieve meshes 402 are respectively slidably connected to the inside of the three screening frames 401, which is convenient for disassembling and installing the screening frames 401 and the sieve meshes 402, and convenient for replacing sieve meshes 402 of different specifications to meet different screening requirements.

The adsorption cotton 504 is arranged inside the exhaust frame 501 at the lower end of the activated carbon 503. The fan 505 is arranged inside the exhaust frame 501 at the lower end of the adsorption cotton 504. During the process of screening raw materials, the fan 505 starts to generate suction, and the air with dust in the box body 1 is sucked into the exhaust frame 501. First, it passes through the adsorption cotton 504, and the adsorption cotton 504 adsorbs the tiny particles and some harmful substances in the air. Then the air passes through the activated carbon 503, and the activated carbon 503 adsorbs the harmful gases and odors in the air. Finally, it passes through the filter net 502, and the filter net 502 blocks the larger particles and impurities. After this series of treatments, the relatively clean air is discharged from the exhaust frame 501, which can give full play to the advantages of each filter layer and improve the overall performance and efficiency of the dust removal and purification structure 5.

[0035] The blocking structure 6 includes a connecting plate 601, two electric telescopic rods 602, two connecting blocks 603, a blocking block 604, a stabilizing frame 605 and a collection box 606. The connecting plate 601 is arranged at the upper center of one side wall of the box body 1. The two electric telescopic rods 602 are respectively arranged at the front and rear of the center of the lower end surface of the connecting plate 601.

The stabilizing frame 605 is arranged on one side wall of the lower end surfaces of the two connecting blocks 603 and the blocking block 604. The collection box 606 is arranged at the lower center of one side of the box body 1. After the screened raw materials are discharged, the electric telescopic rods 602 receive instructions and start to extend. The extension of the electric telescopic rods 602 pushes the connecting blocks 603 to rise, thereby driving the blocking block 604 to move upward. After the blocking block 604 moves upward, the discharge port 9 originally blocked by the blocking block 604 is opened, and the screened raw materials can pass through the discharge port 9 and be discharged. Since the collection box 606 is placed at a suitable position below the discharge port 9, the discharged raw materials can smoothly fall into the collection box 606, realizing orderly collection. The blocking block 604 and the discharge port 9 are mutually adapted. The mutually adapted design ensures the tightness of the block, effectively preventing material leakage when discharging is not required.

[0036] The feeding structure 7 includes a connecting pipe 701, a suction pipe 702, two flanges 703, four bolts 704, a suction pump 705 and a material placement box 706. The connecting pipe 701 is arranged at the center of the upper end surface of the box body 1. The suction pipe 702 is arranged on the upper end surface of the connecting pipe 701. The two flanges 703 are respectively arranged at one end of the connecting pipe 701 and the suction pipe 702. The four bolts 704 are arranged in a circular array on the upper end surface of the upper flange 703. The material placement box 706 is arranged at the lower center of one side of the box body 1. The suction pump 705 is arranged at the center of the lower inner wall of the material placement box 706. One end of the suction pipe 702 is fixedly connected to the output end of the suction pump 705.

[0037] When feeding, the suction pump 705 is started. The suction pump 705 generates suction, so that the materials in the material placement box 706 are sucked in. The materials pass through the output end of the suction pump 705, the suction pipe 702, and the connecting pipe 701 in sequence, and finally enter the interior of the box body 1. The connecting pipe 701 and the suction pipe 702 are connected by two flanges 703 and fixed by four bolts 704 to ensure a tight connection and prevent material leakage. One end of the four bolts 704 sequentially penetrates the upper end surface of the upper flange 703 and the upper end surface of the lower flange 703 and leads to the interior of the lower flange 703, and the ends are all threadedly connected inside the lower flange 703. The threaded connection method provides a strong and stable connection force, which can withstand the pressure and vibration during the feeding process, preventing the interface from loosening and material leakage.

[0038] Working principle: When performing the feeding operation, the suction pump 705 is started. The suction pump 705 generates suction, causing the materials in the material placement box 706 to be sucked in. The materials pass through the output end of the suction pump 705, the suction pipe 702, and the connecting pipe 701 in sequence, and finally enter the inside of the box body 1. The connecting pipe 701 and the suction pipe 702 are connected by two flanges 703 and fixed with four bolts 704 to ensure a tight connection and prevent material leakage. The raw materials fall on the screening structure 4, and the three vibrators 403 work simultaneously. The output end of the vibrator 403 drives the screening frame 401 to vibrate. Since the sieve mesh 402 is arranged at the lower center inside the screening frame 401, the raw materials fall on the sieve mesh 402. Under the action of vibration, the smaller particle raw materials can pass through the sieve mesh 402 and fall downward, while the larger particle raw materials remain on the sieve mesh 402. The mesh sizes of the sieve meshes 402 on the three screening frames 401 are different, so as to realize the classification screening of the raw materials, making the whole device more miniaturized and efficient.

[0039] During the screening process, the dust generated is sucked by starting the suction of the fan 505. The air with dust in the box body 1 is sucked into the exhaust rack 501. First, it passes through the adsorption cotton 504. The adsorption cotton 504 adsorbs the tiny particles and some harmful substances in the air. Then the air passes through the activated carbon 503. The activated carbon 503 adsorbs the harmful gases and odors in the air. Finally, it passes through the filter screen 502. The filter screen 502 blocks the larger particles and impurities. After this series of treatments, the relatively clean air is discharged from the exhaust rack 501, which can give full play to the advantages of each filter layer and improve the overall performance and efficiency of the dust exhaust purification structure 5. The screened raw materials slide down along the guide plate 8. When it is necessary to discharge the screened raw materials, the electric telescopic rod 602 starts to extend after receiving the instruction. The extension of the electric telescopic rod 602 pushes the connecting block 603 to rise, thereby driving the blocking block 604 to move upward. After the blocking block 604 moves upward, the discharge port 9 originally blocked by the blocking block 604 is opened, and the screened raw materials can pass through the discharge port 9 and be discharged. Since the collection box 606 is placed at a suitable position below the discharge port 9, the discharged raw materials can smoothly fall into the collection box 606 to achieve orderly collection. The whole process is controlled and adjusted through the control panel 3.

[0040] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
