Description

Technical Field

[0001] This utility model belongs to the field of dishwashing powder collection device, specifically an automatic collection device for ultra-fine dishwashing powder screening. Background Technology

[0002] Ultrafine dishwasher powder is a cleaning agent specially designed for dishwashers or hand washing. Its main ingredients include phosphates or silicates, oxygen-based or chlorine-based bleach, polycarbonate, nonionic surfactants, and enzymes (such as protease and amylase). These ingredients work together to remove grease, food residue, and stains, achieving a highly effective cleaning result.

[0003] Staff will mix all the prepared dishwashing powder ingredients together in a certain proportion, remove the moisture, and then use a sieve to screen out particles that do not meet the specifications. Finally, they will package the powder in batches using packaging materials with good moisture-proof properties. Through long-term use and observation, it was found that manual collection during the screening of ultrafine dishwashing powder makes it difficult to ensure a uniform amount of material collected each time, resulting in inconsistent quality of the screened dishwashing powder.

[0004] Therefore, this utility model provides an automatic collection device for screening ultrafine dishwashing powder. Summary of the Invention

[0005] To overcome the shortcomings of existing technologies and solve at least one of the problems mentioned in the background art, an automatic collection device for ultrafine dishwasher powder screening is proposed.

The process involves sieving out the qualified dishwashing powder by pressing down; the collecting component includes a motor; the motor is fixed to the side wall of the conveyor seat; a conveyor belt is fixedly connected to the output end of the motor; the conveyor belt rotates inside the conveyor seat; an electric push rod is fixed to the top of the conveyor belt; a fixing plate is fixed to the output end of the electric push rod; a collection bag is installed on the top of the fixing plate; an inlet is fixed to the top of the collection bag; the inlet and outlet pipes are correspondingly arranged; the collection bag and the inlet are both made of elastic material and are connected; this step, by setting up a motor, conveyor belt, electric push rod, fixing plate, collection bag and inlet, can quickly and accurately collect the sieved ultrafine dishwashing powder, reducing manual operation and thus improving overall production efficiency. At the same time, this setting can ensure that the sieved ultrafine dishwashing powder is collected in a timely and complete manner, reducing cross-contamination caused by dust, reducing waste of raw materials, lowering production costs, and ensuring product quality.

[0007] Preferably, the diversion component includes a fixed shaft; the fixed shaft is fixed to the inner wall of the second screening box; a guide plate is rotatably connected to the middle of the side wall of the fixed shaft; multiple dispersing plates are fixed to the middle of the side wall of the guide plate; the ends of the dispersing plates are arranged in an arc shape. This step, by setting the fixed shaft, guide plate, and dispersing plates, can break up the ultrafine dishwashing powder into batches for screening, making its distribution on the screen more uniform, reducing the problem of uneven screening caused by the accumulation or agglomeration of dishwashing powder, and the impact force of the dishwashing powder poured in batches is dispersed when it hits the screen, reducing the direct impact on the screen, thereby extending the service life of the screen.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Specific implementation examples are given below.

[0023] like Figures 1 to 4 As shown, an automatic collection device for ultrafine dishwashing powder according to an embodiment of the present invention includes a conveyor base 1; a pair of support rods 11 are fixed to the top of the conveyor base 1; a first screening box 12 is installed at the other end of the support rods 11; a discharge pipe 13 is fixedly connected to the bottom of the first screening box 12; a collection component is provided in the middle of the side wall of the conveyor base 1, which can automatically collect the screened ultrafine dishwashing powder; the collection component and the discharge pipe 13 are correspondingly arranged; a second screening box 14 is slidably connected to the middle of the inner side wall of the first screening box 12; a disassembly component is provided between the first screening box 12 and the second screening box 14, which can separate the first screening box 12 and the second screening box 14 and clean their interiors; an inlet 15 is opened at the top of the second screening box 14; a diversion component is provided in the middle of the inner side wall of the second screening box 14, which can disperse the ultrafine dishwashing powder poured in from the inlet 15; A screening component is located in the middle of the side wall of the flow assembly. This screening component will separate the dishwasher powder that meets the requirements under multiple taps. During operation, the operator starts the receiving component, which moves to the bottom of the discharge pipe 13, then moves upward and embeds itself inside the discharge pipe 13. The ultrafine dishwasher powder to be screened is then poured into the inlet 15. The ultrafine dishwasher powder will fall into the second screening box 14, where it is dispersed and diverted by the diversion component. The powder then falls onto the screening component. When the diversion component rotates, it will continuously vibrate the screening component. The ultrafine dishwasher powder will jump with the vibration of the screening component, so that the ultrafine dishwasher powder that meets the size requirements falls into the receiving component through the discharge pipe 13 and is collected by the receiving component. After the screening task is completed, the operator uses the disassembly component to separate and clean the first screening box 12 and the second screening box 14.

[0024] like Figure 1 and Figure 2As shown, the receiving assembly includes a motor 2; the motor 2 is fixed to the side wall of the conveyor seat 1; a conveyor belt 21 is fixedly connected to the output end of the motor 2; the conveyor belt 21 rotates inside the conveyor seat 1; an electric push rod 22 is fixed to the top of the conveyor belt 21; a fixing plate 23 is fixedly connected to the output end of the electric push rod 22; a collection bag 24 is installed on the top of the fixing plate 23; an inlet 25 is fixed to the top of the collection bag 24; the inlet 25 and the discharge pipe 13 are correspondingly arranged; the collection bag 24 and the inlet 25 are both made of elastic material and are connected; during operation, the operator starts the motor 2, which drives the conveyor belt 21 to rotate inside the conveyor seat 1. When the conveyor belt 21 rotates, it drives the electric push rod 22, the fixing plate 23, the collection bag 24, and the inlet 25 to move. When the inlet 25 moves to directly below the discharge pipe 13, the electric push rod 22 is activated, and the electric push rod 22 pushes the fixing plate 23. 3. Moving upwards: At this time, the fixing plate 23 will drive the collection bag 24 and the inlet 25 to move upwards simultaneously. Since the collection bag 24 and the inlet 25 are both made of elastic material, the inlet 25 will be embedded inside the discharge pipe 13. When the sieved ultrafine dishwashing powder flows out of the discharge pipe 13, it will pass through the inlet 25 and enter the collection bag 24, where it will be collected. This step, through the setting of motor 2, conveyor belt 21, electric push rod 22, fixing plate 23, collection bag 24 and inlet 25, can quickly and accurately collect the sieved ultrafine dishwashing powder, reducing manual operation and thus improving overall production efficiency. At the same time, this setting can ensure that the sieved ultrafine dishwashing powder is collected in a timely and complete manner, reducing cross-contamination caused by dust, reducing waste of raw materials, lowering production costs, and ensuring product quality.

[0025] like Figure 4 As shown, the diversion assembly includes a fixed shaft 3; the fixed shaft 3 is fixed to the inner wall of the second screening box 14; a guide plate 31 is rotatably connected to the middle of the side wall of the fixed shaft 3; multiple dispersing plates 32 are fixed to the middle of the side wall of the guide plate 31; the ends of the dispersing plates 32 are arranged in an arc shape; when the ultrafine dishwashing powder enters the interior of the second screening box 14 through the feed inlet 15, it will first come into contact with the guide plate 31 and the dispersing plates 32. Because the guide plate 31 is rotatably connected to the fixed shaft 3, under the push of the ultrafine dishwashing powder, the guide plate 31 will carry the multiple dispersing plates 32. 2. The shaft rotates on the side wall of the fixed shaft 3. During this rotation, the guide plate 31 and the dispersing plate 32 will disperse and divert the ultrafine dishwashing powder. This step, by setting the fixed shaft 3, the guide plate 31 and the dispersing plate 32, can disperse the ultrafine dishwashing powder in batches for screening, making its distribution on the screen more uniform, reducing the problem of uneven screening caused by the accumulation or agglomeration of dishwashing powder. Moreover, when the dishwashing powder is poured in batches, the impact force is dispersed when it hits the screen, reducing the direct impact on the screen and thus extending the service life of the screen.

[0026] like Figure 3 and Figure 4As shown, the screening assembly includes multiple elastic ropes 4; the elastic ropes 4 are fixed to the side wall of the dispersing plate 32; a connecting block 41 is fixed to the end of each elastic rope 4; a slot 42 is opened in the inner wall of the first screening box 12; multiple springs 43 are fixed in the middle of the inner side wall of the slot 42; a screen plate 44 is installed at the other end of each spring 43; the screen plate 44 and the connecting block 41 are correspondingly arranged; when the dispersing plate 32 rotates, the multiple elastic ropes 4 on its side wall will drive the connecting block 41 to rotate simultaneously. Because the connecting block 41 and the screen plate 44 are correspondingly arranged, the multiple connecting blocks 41 will continuously strike the screen during rotation. The plate 44, driven by multiple springs 43, slides back and forth along the inside of the groove 42. At this time, the sieve plate 44 will sieve the dishwashing powder in the vibration. This step, by setting up the elastic rope 4, connecting block 41, groove 42, spring 43 and sieve plate 44, can continuously vibrate the sieve plate 44, which helps the dishwashing powder to form a continuous and uniform throwing motion on the sieve plate 44. This motion mode increases the contact opportunity between the dishwashing powder and the sieve plate 44, thereby improving the sieving efficiency. At the same time, the vibration can also promote the dishwashing powder particles to pass through the sieve holes faster, making the sieving process more efficient.

[0027] like Figure 3 and Figure 4 As shown, the disassembly assembly includes multiple positioning blocks 5; the positioning blocks 5 are fixed on the side wall of the second screening box 14; multiple first positioning grooves 51 are opened in the middle of the inner side wall of the first screening box 12; the first positioning grooves 51 and the positioning blocks 5 are correspondingly arranged; the positioning blocks 5 slide inside the first positioning grooves 51; a second positioning groove 52 is opened in the middle of the inner side wall of the first screening box 12; the second positioning groove 52 and the positioning blocks 5 are correspondingly arranged; the positioning blocks 5 slide inside the second positioning grooves 52; after the ultrafine dishwasher detergent screening task is completed, a large amount of dishwasher detergent particles will remain on the inner walls of the first screening box 12 and the second screening box 14. The operator rotates the second screening box 14 and the first screening box 12, causing the multiple positioning blocks 5 on the side wall of the second screening box 14 to slide within the second positioning grooves 52 fixed on the inner wall of the first screening box 12. When the positioning block 5 enters the first positioning groove 51, the second screening box 14 is pulled upwards to separate it from the first screening box 12. It is then cleaned. This step, through the setting of the positioning block 5, the first positioning groove 51, and the second positioning groove 52, allows the first screening box 12 and the second screening box 14 to be opened and cleaned promptly after screening, removing residual detergent and impurities and preventing their accumulation inside the equipment. This helps extend the equipment's lifespan and reduces the risk of malfunctions caused by dirt and residue. Cleaning the first screening box 12 and the second screening box 14 also removes blockages and accumulated fine powder from the sieve plate 44, improving its flow and increasing the efficiency of the next screening, as detergent will pass through the sieve holes more easily, reducing screening time.

[0028] like Figure 1 , Figure 3 and Figure 4 As shown, a collection plate 6 is provided on the top of the feed inlet 15; the collection plate 6 is fixed on the top of the second screening box 14; this step, by providing a collection plate 6 on the top of the feed inlet 15, can effectively prevent the dishwashing powder from splashing when poured in, reducing the loss and waste of dishwashing powder, and also helps to keep the working environment clean.

[0029] like Figure 1 , Figure 3 and Figure 4 As shown, an observation window 7 is provided in the middle of the side wall of the second screening box 14; the observation window 7 is made of transparent material; by setting the observation window 7, the staff can observe the situation inside the second screening box 14 in real time, which helps to discover and solve problems in time and ensure the smooth progress of the screening process.

[0030] Working principle: The operator activates the receiving assembly, which moves to directly below the discharge pipe 13, then moves upwards and embeds itself inside. The ultrafine dishwasher powder to be screened is then poured into the inlet 15. The powder falls into the second screening box 14, where it is dispersed and diverted by the diversion component. The powder then falls onto the screening assembly. As the diversion component rotates, it continuously vibrates the screening assembly, causing the ultrafine dishwasher powder to jump and bounce. Powder meeting the size requirements falls through the discharge pipe 13 into the receiving assembly, where it is collected. After the screening task is completed, the operator uses the disassembly assembly to remove the powder from the second screening box. The first screening box 12 and the second screening box 14 are separated and cleaned. The operator starts the motor 2, which drives the conveyor belt 21 to rotate inside the conveyor seat 1. When the conveyor belt 21 rotates, it drives the electric push rod 22, the fixing plate 23, the collection bag 24, and the inlet 25 on its top to move. When the inlet 25 moves to the bottom of the discharge pipe 13, the electric push rod 22 is activated. The electric push rod 22 pushes the fixing plate 23 upward. At this time, the fixing plate 23 drives the collection bag 24 and the inlet 25 to move upward synchronously. Because the collection bag 24 and the inlet 25 are made of elastic material, the inlet 25 will be embedded inside the discharge pipe 13. When the screened ultrafine dishwashing powder flows out of the discharge pipe 13, it will pass through... The feed inlet 25 enters the collection bag 24 and is collected by the collection bag 24. When the ultrafine dishwashing powder enters the second screening box 14 through the feed inlet 15, it will first come into contact with the guide plate 31 and the dispersing plate 32. Because the guide plate 31 is rotatably connected to the fixed shaft 3, under the push of the ultrafine dishwashing powder, the guide plate 31 will carry multiple dispersing plates 32 to rotate on the side wall of the fixed shaft 3. At this time, the guide plate 31 and the dispersing plate 32 will disperse and divert the ultrafine dishwashing powder during the rotation. When the dispersing plate 32 rotates, multiple elastic ropes 4 on its side wall will drive the connecting block 41 to rotate at the same time. Because the connecting block 41 and the sieve plate 44 are correspondingly set, the multiple connecting blocks 41 will continuously knock during the rotation. The sieve plate 44 is struck, causing it to slide back and forth along the inside of the groove 42 under the action of multiple springs 43. At this time, the sieve plate 44 will sieve the dishwashing powder in the vibration. After the ultrafine dishwashing powder sieving task is completed, a large number of dishwashing powder particles will remain on the inner walls of the first sieve box 12 and the second sieve box 14. The staff rotates the second sieve box 14 and the first sieve box 12, causing multiple positioning blocks 5 on the side wall of the second sieve box 14 to slide in the second positioning groove 52 fixed on the inner wall of the first sieve box 12. When the positioning block 5 enters the first positioning groove 51, the second sieve box 14 is lifted upward, which can separate the second sieve box 14 and the first sieve box 12, and then clean them.
