Description

Technical Field

[0001] This utility model relates to the field of sieving machines, and in particular to an anti-clogging milk powder sieving machine. Background Technology

[0002] Milk powder is a powdered food made primarily from fresh cow's or goat's milk through a series of processing steps. Specifically, the production process includes sterilization, concentration, and spray drying, ultimately removing a large amount of water from the milk to facilitate storage and transportation. Milk powder retains the main nutrients of fresh milk, such as protein, fat, carbohydrates, vitamins, and minerals, possessing similar nutritional value, but with greater stability and easier storage and preparation. It is widely used in the food industry as infant formula, baking ingredients, and beverage additives, and is also a staple nutritional food in households, especially suitable for those who need nutritional supplementation or cannot conveniently drink fresh milk directly. There are various types of milk powder, including whole milk powder, skim milk powder, and modified milk powder, to meet the needs of different consumers.

[0003] In existing technologies, sieving machines are a crucial step in milk powder processing, ensuring that the milk powder meets relevant quality standards and regulations. By using sieving machines, the particle size distribution and impurity content of milk powder can be strictly controlled, improving its overall quality. However, during sieving, milk powder particles are not perfectly spherical and exhibit irregularities. Some irregularly shaped particles can become stuck in the sieve holes at specific angles or orientations, causing clogging. Furthermore, the uneven particle size distribution means that many particles are close to the sieve hole size, which also tend to accumulate at the holes, further contributing to clogging and reducing the sieving effect and efficiency. Utility Model Content

[0004] The main purpose of this invention is to provide an anti-clogging milk powder sieving machine, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A clog-resistant milk powder sieving machine includes a base and a vibrating frame. Several first springs are fixedly connected between the base and the vibrating frame in a circular array. A vibrating motor is fixedly connected inside the vibrating frame, and an eccentric block is fixedly connected to the output end of the vibrating motor. A screen frame is also fixedly connected to the top surface of the vibrating frame, and a screen plate is fixedly connected inside the screen frame. Several screen holes are opened on the top surface of the screen plate. Discharge ports of varying heights are fixedly connected to both sides of the outer wall of the screen frame. A dust cover is fixedly connected to the top surface of the screen frame, and a feed inlet is fixedly connected to the top surface of the dust cover. An anti-clogging mechanism is provided below the screen plate, and the anti-clogging mechanism includes a rotating disk, a lifting disk, a guiding disk, and guiding needles. The rotating disk is fixedly connected to the output end of the vibrating motor, and the lifting disk is fixedly connected to the vibrating frame by a second spring. The guiding disk is fixedly connected to the top of the lifting rod on the top surface of the lifting disk, and several guiding needles are fixedly connected to the top surface of the guiding disk.

[0007] As a preferred technical solution, a through hole is provided at the center of the top surface of the sieve plate.

[0008] As a preferred technical solution, a mounting hole is provided at the center of the top surface of the vibrating frame, and a linear bearing is fixedly installed inside the mounting hole.

[0009] As a preferred technical solution, the rotating disk is fixedly installed on the top surface of the upper output end of the vibration motor, and a set of symmetrical hemispheres are fixedly installed on the top surface of the rotating disk.

[0010] As a preferred technical solution, a set of symmetrical wedge plates are fixedly installed on the bottom surface of the lifting plate, and a lifting rod is fixedly installed on the top surface of the lifting plate. The lifting rod is inserted and installed together with the linear bearing, and the lifting rod also passes through the through hole. The second spring is sleeved on the outside of the guide plate, and the second spring is also fixedly installed between the opposing walls of the lifting plate and the vibrating frame. The top surface of the guide plate has a sleeve hole, and the guide plate is fixedly sleeved on the outside of the lifting rod through the sleeve hole and located below the screen plate.

[0011] As a preferred technical solution, the top surface of the guide plate is provided with several arc-shaped material discharge ports, and the top surface of the guide plate is also fixedly equipped with several guide needles corresponding to the screen holes.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In this invention, an anti-clogging mechanism is provided. The rotating disk is fixed to the output end of the vibrating motor. When the motor runs, the rotating disk rotates accordingly, and the hemispherical ball on it presses against the wedge plate on the bottom of the lifting disk. Since the lifting disk and the vibrating frame are connected by a second spring, and the lifting rod is inserted into the linear bearing, the hemispherical ball pressing against the wedge plate will cause the lifting disk to move upward, thereby driving the guide disk and guide needle to rise. The guide needle corresponds to the sieve hole and can be inserted into the sieve hole to effectively unclog the sieve hole and prevent the sieve hole from being blocked by milk powder particles. When the hemispherical ball leaves the wedge plate, under the action of the second spring, the lifting disk, guide disk and guide needle fall back. This cycle continues to keep the sieve hole unobstructed, thereby avoiding the problem of clogging when screening milk powder through the sieve machine. This gives the sieve machine an anti-clogging function, thereby improving the screening effect and screening efficiency of milk powder. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figure 1 - Figure 5 As shown, an anti-clogging milk powder sieving machine includes a base 1 and a vibrating frame 2. Several first springs 3 are fixedly connected between the base 1 and the vibrating frame 2 in a circular array. A vibrating motor 4 is fixedly connected inside the vibrating frame 2. An eccentric block 5 is fixedly connected to the output end of the vibrating motor 4. A sieve frame 6 is also fixedly connected to the top surface of the vibrating frame 2. A sieve plate 7 is fixedly connected inside the sieve frame 6. Several sieve holes 8 are opened on the top surface of the sieve plate 7. Discharge ports 9 of different heights are fixedly connected to both sides of the outer wall of the sieve frame 6. A dust cover 10 is fixedly connected to the top surface of the sieve frame 6. A feed inlet 11 is fixedly connected to the top surface of the dust cover 10.

[0022] The specific sieving principle of this sieving machine for milk powder is as follows:

[0023] When the vibration motor 4 is turned on, its output drives the eccentric block 5, which is fixedly connected to it, to rotate. The eccentric block 5 generates centrifugal force during rotation; this centrifugal force is the excitation force. Since several first springs 3 are fixedly connected to the base 1 and the vibrating frame 2 in a circular array, the first springs 3 not only buffer the vibration of the screen frame 6 but also ensure that the vibration is transmitted more stably and evenly. The excitation force causes the vibrating frame 2 to vibrate. Because the top surface of the vibrating frame 2 is fixedly connected to the screen frame 6, the screen frame 6 will also vibrate accordingly. When milk powder enters the screen frame 6 through the feed inlet 11 on the top surface of the dust cover 10 and falls onto the screen plate 7, the milk powder continuously jumps and rolls on the screen plate 7 due to the vibration of the screen frame 6, because the screen plate 7 has several screen holes 8. Milk powder particles that meet the size requirements of the screen holes 8 will pass through the screen holes 8 and be discharged through the discharge port 9 at a lower position on one side of the outer wall of the screen frame 6. Unqualified milk powder that is filtered down from the top surface of the screen plate 7 will be discharged through the discharge port 9 at a higher position on the other side of the outer wall of the screen frame 6. In this way, the milk powder is screened.

[0024] A clogging prevention mechanism 12 is provided below the sieve plate 7. The clogging prevention mechanism 12 includes a rotating disk 16, a lifting disk 18, a guide disk 22, and guide needles 25. The rotating disk 16 is fixedly connected to the output end of the vibration motor 4. The lifting disk 18 is fixedly connected to the vibrating frame 2 by a second spring 21. The guide disk 22 is fixedly connected to the top of the lifting rod 20 on the top surface of the lifting disk 18. Several guide needles 25 are also fixedly connected to the top surface of the guide disk 22.

[0025] like Figure 3 As shown, a through hole 13 is provided in the center of the top surface of the sieve plate 7. The through hole 8 is provided on the sieve plate 7 to provide a passage for the lifting rod 20 to pass through, so that the lifting rod 20 can move up and down under the sieve plate 7. This ensures that the lifting rod 20 can pass through the sieve plate 7 smoothly, so that the movement of the lifting plate 18, the guiding plate 22 and the guiding needle 25 is not obstructed by the sieve plate 7.

[0026] like Figure 4As shown, a mounting hole 14 is provided at the center of the top surface of the vibrating frame 2, and a linear bearing 15 is fixedly installed in the mounting hole 14. The mounting hole 14 is used to install the linear bearing 15. The linear bearing 15 can provide guidance and support for the up and down movement of the lifting rod 20. The characteristics of the linear bearing 15 enable the lifting rod 20 to maintain linear movement during the movement, reduce radial sway and friction, and ensure the stability and accuracy of the movement of the lifting rod 20.

[0027] like Figure 5 As shown, the rotating disk 16 is fixedly installed on the top surface of the output end of the vibrating motor 4, and a set of symmetrical hemispheres 17 are fixedly installed on the top surface of the rotating disk 16. The rotating disk 16 is fixedly connected to the output end of the vibrating motor 4. When the vibrating motor 4 is running, it drives the rotating disk 16 to rotate, and the hemispheres 17 on the rotating disk 16 also rotate. During the rotation, the hemispheres 17 will contact the wedge plate 19 on the bottom surface of the lifting disk 18 and generate a squeezing effect, which converts the circular motion of the rotating disk 16 into the vertical linear motion of the lifting disk 18, providing a power source for the anti-blocking mechanism 12, so that the guide disk 22 and the guide needle 25 can rise and fall periodically to clean the screen hole 8.

[0028] like Figure 5 As shown, a set of symmetrical wedge plates 19 are fixedly installed on the bottom surface of the lifting plate 18, and a lifting rod 20 is fixedly installed on the top surface of the lifting plate 18. The lifting rod 20 is inserted and installed together with the linear bearing 15, and the lifting rod 20 also passes through the through hole 13. The second spring 21 is sleeved on the outside of the guide plate 22, and the second spring 21 is also fixedly installed between the opposing walls of the lifting plate 18 and the vibrating frame 2. The top surface of the guide plate 22 has a sleeve hole 23, and the guide plate 22 is fixedly sleeved on the outside of the lifting rod 20 through the sleeve hole 23 and located below the screen plate 7. When the hemispherical ball 17 on the rotating plate 16 presses the lifting plate 18, When the wedge plate 19 on the bottom surface of the 8 is in place, the lifting plate 18 is subjected to an upward force. It moves upward under the guidance of the linear bearing 15 through the lifting rod 20 and compresses the second spring 21. When the hemisphere 17 leaves the area below the wedge plate 19, the elastic force of the second spring 21 causes the lifting plate 18 to move downward and reset. The guide plate 22 is fixed to the lifting rod 20 through the sleeve hole 23 and moves up and down with the lifting plate 18. This realizes the up and down reciprocating motion of the lifting plate 18 and the guide plate 22, so that the guide needle 25 on the guide plate 22 can periodically insert and leave the sieve hole 8 to effectively unclog the sieve hole 8 and prevent the sieve hole 8 from becoming blocked.

[0029] like Figure 5As shown, the top surface of the guide plate 22 is provided with several arc-shaped discharge ports 24, and several guide pins 25 corresponding to the sieve holes 8 are also fixedly installed on the top surface of the guide plate 22. When the guide plate 22 rises, the guide pins 25 are inserted into the sieve holes 8 to push out or clear the milk powder particles blocked in the sieve holes 8, so that the sieve holes are unobstructed. The arc-shaped discharge ports 24 facilitate the smooth fall of milk powder particles that pass through the sieve holes 8, and prevent milk powder from accumulating on the guide plate 22.

[0030] The specific operating principle of the anti-clogging mechanism 12 when used in conjunction with the sieving machine to sieve milk powder is as follows:

[0031] During screening, when the rotating disk 16 rotates along with the output of the vibrating motor 4, it drives the symmetrical hemispheres 17 mounted on the top surface to rotate synchronously. When the hemispheres 17 contact the wedge plate 19 mounted on the bottom surface of the lifting disk 18 during rotation, they will contact the inclined surface of the wedge plate 19 and exert a squeezing force on the lifting disk 18 through the wedge plate 19. The lifting disk 18 will move upward, forcing the second spring 21 to tighten. The lifting rod 20 mounted on the top surface of the lifting disk 18 will be pushed upward by the lifting disk 18 along the linear bearing 15 mounted in the mounting hole 14, and push the guide disk 22, which is fixed to the outer wall through the sleeve hole 23, to move upward synchronously. During the process, the guide needles 25 installed on the top surface are inserted into the sieve holes 8 on the top surface of the sieve plate 7, and the milk powder blocking the sieve holes 8 is lifted and cleared. When the rotating disk 16 rotates and the hemisphere 17 leaves the bottom surface of the wedge plate 19, the second spring 21 will perform an elastic recovery and extension operation, and push the lifting disk 18 to move downward. The lifting rod 20 moves down along the linear bearing 15 and simultaneously drives the guide disk 22 to move down, allowing the guide needles 25 to move out of the sieve holes 8. This cycle continues to keep the sieve holes 8 unobstructed, thereby avoiding the problem of clogging when screening milk powder through the sieve machine. This gives the sieve machine an anti-clogging function, thereby improving the screening effect and efficiency of milk powder.
