Description

Technical Field

[0001] This utility model relates to the field of feeding machine technology, specifically to a uniform speed feeding machine for flour processing. Background Technology

[0002] Flour is a powder made from wheat and is the most basic raw material for making pasta products. Flour processing is the process of converting wheat into edible flour. The processing steps include: raw material preparation and processing, grinding and sieving, and flour processing and packaging. In the raw material preparation and processing, the wheat raw material first needs to be sieved and conditioned. During the sieving process, the wheat raw material needs to be fed into the sieving device at a uniform speed by a feeder. The sieving device removes foreign objects such as soil, stones, weeds, and metal fragments from the wheat. The feeder is usually a belt feeder, which consists of a feeding support, conveyor belt, and rollers. The wheat enters the conveyor belt through the feed hopper, and the control plate makes the wheat evenly distributed on the conveyor belt. Then, the conveyor belt transports the material at a uniform speed to the flour processing equipment.

[0003] CN208631543U discloses an intelligent uniform speed feeder for flour processing, including a feeding support. The feeding support has a first U-shaped groove with a discharge hopper at one end. Symmetrically distributed through holes are located within the first U-shaped groove. Symmetrically distributed protective plates are also located on the first U-shaped groove. A roller is installed within each through hole, and a conveyor belt is wrapped around the roller. A feed hopper is located on the protective plate, including a feed hole with a feed plate inside. This intelligent uniform speed feeder for flour processing uses a control plate to evenly distribute wheat on the conveyor belt, providing uniform feeding to the flour processing equipment. This makes feeding controllable and ensures uniformity. It also quickly and effectively clears blockages in the feed hopper, replacing traditional manual clearing methods, thus greatly reducing the labor intensity of workers and improving work efficiency.

[0004] While existing feeders offer numerous advantages during use, they still suffer from several problems. Their anti-clogging mechanisms are not robust enough, requiring manual assistance from staff to clear blockages when materials become trapped inside the hopper, resulting in high workload for workers. Utility Model Content

[0005] To address the problems in the existing technology, this utility model provides a uniform speed feeder specifically for flour processing.

[0006] The technical solution adopted by this utility model to solve its technical problem is a uniform speed feeder for flour processing, including a frame, a hopper, fixed blocks, and a fixed seat. The frame has equidistant parallel support rollers inside, and a conveyor belt is sleeved on the outside of the support rollers. Equidistant parallel partition plates are glued to the outer wall of the conveyor belt. Drive plates are screwed to the outer walls of both sides of the partition plates. A hopper is located at the upper end of the frame, and a rotating shaft is rotatably installed inside the hopper. A circular array of feeding plates is screwed to the outer wall of the rotating shaft. A rectangular array of fixed blocks is welded to the outer wall of the upper end of the frame. A rectangular array of fixed seats is located on the outer wall of the hopper. Springs are welded to the outer wall of the fixed seats, and an extension plate is glued to the outer wall of the springs. Equidistant parallel protrusions are integrally formed on the outer wall of the extension plate.

[0007] By adopting the above technical solution, the outer space of the conveyor belt can form multiple independent material storage and conveying spaces through the partition plates, which can effectively avoid material accumulation or displacement and ensure that the amount of material conveyed per unit time is uniform and stable. When the partition plates and drive plates move with the conveyor belt, the drive plate will contact the feeding plate, thereby driving the feeding plate and the rotating shaft to rotate circumferentially inside the hopper. Based on the distance between the multi-point partition plates and drive plates, the rotation angle of the feeding plate and the rotating shaft can be controlled. When the feeding plate rotates, the material entering between the feeding plates inside the hopper can be driven to rotate to the lower end of the rotating shaft and fall between the partition plates due to its own weight, thereby realizing the quantitative drop of the material and ensuring that the amount of material stored between the partition plates is the same, which provides a guarantee for subsequent uniform feeding. When the drive plate moves out of the hopper through the through hole, the drive plate enters between the extension plates and contacts the protrusion. Thus, the contact between the drive plate and the protrusion during the operation of the conveyor belt can make the hopper vibrate, preventing the material from stagnating or blocking in the hopper and ensuring the smoothness of feeding.

[0008] Specifically, baffles are glued and fixed to both sides of the upper end of the inner wall of the frame, and the outer walls of the baffles are in contact with the outer walls of the conveyor belt and the partition plate, respectively.

[0009] By adopting the above technical solution, the baffle plate and the partition plate can effectively prevent materials from falling from both sides of the conveyor belt, avoid material pollution and waste, and ensure that materials are transported in an orderly manner within the partition area, maintaining the uniformity of the feeding amount.

[0010] Specifically, a collar is screwed to one side of the outer wall of the hopper, and a friction ring is bonded to the inner wall of the collar. The inner ring of the friction ring is in contact with the outer wall of the rotating shaft.

[0011] By adopting the above technical solution, the sleeve ensures that the friction ring is in a stable position outside the rotating shaft, and the friction ring can generate a certain damping effect through friction with the rotating shaft, which prevents the feeding amount from suddenly increasing due to the rotating shaft rotating too fast, thus helping to control the feeding speed and ensure the uniformity of feeding.

[0012] Specifically, through holes are symmetrically provided on both sides of the outer wall of the hopper. The size of the through holes is larger than the size of the drive plate, and the through holes are located between the fixed seats.

[0013] By adopting the above technical solution, the through-hole provides a channel for the drive plate to pass through the hopper, allowing the drive plate to contact the extension plate outside the hopper, thereby realizing the vibration drive of the hopper during the operation of the conveyor belt. The through-hole size is larger than the drive plate and is located between the fixed seats, which ensures that the normal movement of the drive plate is not obstructed, and avoids interference with the fixed seats and other components, thus ensuring the effective operation of the vibration drive mechanism.

[0014] Specifically, the fixing block is provided with a positioning bolt inside, and the positioning bolt passes through the end of the fixing block and is threaded to the outer wall of the hopper. Supporting springs are sleeved on both sides of the outer wall of the positioning bolt, and the two supporting springs are distributed on both sides of the fixing block.

[0015] By adopting the above technical solution, the positioning bolts connect the fixing block to the hopper, thus fixing the hopper to the frame. Meanwhile, support springs distributed on both sides of the fixing block provide elastic support for the hopper. When the hopper is subjected to vibration, the support springs act as a buffer, reducing the impact of vibration on the frame and other components, and making the vibration of the hopper more stable.

[0016] Specifically, the protrusions are designed with an arc shape, the spacing between the protrusions is greater than the thickness of the drive plate, the drive plate is located between the extension plates, and the drive plate is in contact with the outer wall of the extension plate.

[0017] By adopting the above technical solution, the arc-shaped protrusion design can reduce the friction and impact when the drive plate and the extension plate come into contact, making the interaction between the two more gentle and reducing the wear rate of the components. The protrusion spacing is greater than the thickness of the drive plate and the drive plate is located between the extension plates, ensuring that the drive plate can smoothly contact the protrusions and push the extension plates. The spring is used for the extension plate to swing, which facilitates the drive plate to move between the protrusions and thus drive the hopper to vibrate.

[0018] The beneficial effects of this utility model are:

[0019] The present invention describes a uniform speed feeder for flour processing. The drive plate enters between the extension plates and contacts the protrusion. By utilizing the contact between the drive plate and the protrusion during the operation of the conveyor belt, the hopper vibrates, preventing material from stagnating or clogging in the hopper and ensuring smooth feeding.

[0020] The present invention describes a uniform feeder for flour processing. When the feeding plate rotates, the material entering between the feeding plates inside the hopper can be driven to rotate to the lower end of the rotating shaft and fall between the partition plates due to its own weight. This achieves quantitative falling of the material and ensures that the amount of material between the partition plates is the same, thus providing a guarantee for subsequent uniform feeding.

[0029] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0030] To save manpower and improve efficiency, as one embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, the present invention discloses a uniform feeder for flour processing, comprising a frame 1, a hopper 2, a fixing block 3, and a fixing seat 4. The frame 1 has equidistant parallel support rollers 11 inside, and a conveyor belt 12 is sleeved on the outside of the support rollers 11. Equidistant parallel partition plates 13 are bonded to the outer wall of the conveyor belt 12. Drive plates 14 are screwed to the outer walls of both sides of the partition plates 13. The hopper 2 is located at the upper end of the frame 1. A rotating shaft 21 is rotatably installed inside the hopper 2. Feeding plates 22 arranged in a circular array are screwed to the outer wall of the rotating shaft 21. Fixing blocks 3 arranged in a rectangular array are welded to the upper outer wall of the frame 1. Fixing seats 4 arranged in a rectangular array are located on the outer wall of the hopper 2. Springs 41 are welded to the outer wall of the fixing seat 4. An extension plate 42 is bonded to the outer wall of the springs 41. Equidistant parallel protrusions 43 are integrally formed on the outer wall of the extension plate 42.

[0031] In use, the space outside the conveyor belt 12 can form multiple independent material storage and conveying spaces through the partition plate 13, which can effectively prevent material accumulation or displacement and ensure that the amount of material conveyed per unit time is uniform and stable. When the partition plate 13 and the drive plate 14 move with the conveyor belt 12, the drive plate 14 will contact the feeding plate 22, thereby driving the feeding plate 22 and the rotating shaft 21 to rotate circumferentially inside the hopper 2. According to the distance between the multi-point partition plate 13 and the drive plate 14, the rotation angle of the feeding plate 22 and the rotating shaft 21 can be controlled. When the feeding plate 22 rotates, the material... Material entering the hopper 2 between the feeding plates 22 can be driven to rotate to the lower end of the rotating shaft 21 and fall between the partition plates 13 due to its own weight, thereby achieving quantitative falling of material and ensuring that the amount of material in the partition plates 13 is the same, which provides a guarantee for subsequent uniform feeding. When the drive plate 14 moves out of the hopper 2 through the through hole 25, the drive plate 14 enters between the extension plates 42 and contacts the protrusion 43. Thus, the contact between the drive plate 14 and the protrusion 43 during the operation of the conveyor belt 12 can cause the hopper 2 to vibrate, preventing material from being stuck or blocked in the hopper 2 and ensuring smooth feeding.

[0032] For the purpose of blocking material, for example, such as Figure 2 As shown, baffle plates 15 are glued and fixed on both sides of the upper end of the inner wall of the frame 1, and the outer walls of the baffle plates 15 are in contact with the outer walls of the conveyor belt 12 and the partition plate 13, respectively.

[0033] When in use, the baffle plate 15, together with the partition plate 13, can effectively prevent materials from falling from both sides of the conveyor belt 12, avoid material pollution of the working environment and waste, and ensure that materials are transported in an orderly manner within the partition area, maintaining the uniformity of the feeding amount.

[0034] For controlled rotation, for example, such as Figure 3As shown, a collar 23 is screwed to one side of the outer wall of the hopper 2, and a friction ring 24 is glued and fixed to the inner wall of the collar 23. The inner ring of the friction ring 24 is in contact with the outer wall of the rotating shaft 21.

[0035] During use, the sleeve ensures that the friction ring 24 is stably positioned outside the rotating shaft 21, and the friction ring 24 can generate a certain damping effect through friction with the rotating shaft 21, which prevents the feeding amount from suddenly increasing due to excessive rotation speed of the rotating shaft 21, thus helping to control the feeding speed and ensure the uniformity of feeding.

[0036] To provide a movement path, for example, such as Figure 3 As shown, through holes 25 are symmetrically opened on both outer walls of the hopper 2. The size of the through holes 25 is larger than the size of the drive plate 14, and the through holes 25 are located between the fixed seats 4.

[0037] In use, the through hole 25 provides a channel for the drive plate 14 to pass through the hopper 2, allowing the drive plate 14 to contact the extension plate 42 outside the hopper 2, thereby realizing the vibration drive of the hopper 2 when the conveyor belt 12 is running. The through hole 25 is larger than the drive plate 14 and is located between the fixed seats 4, which ensures that the normal movement of the drive plate 14 is not obstructed, and avoids interference with the fixed seats 4 and other components, ensuring the effective operation of the vibration drive mechanism.

[0038] To maintain the vibration position, for example, such as Figure 5 As shown, a positioning bolt 31 is provided inside the fixing block 3, and the positioning bolt 31 passes through the end of the fixing block 3 and is threaded to the outer wall of the hopper 2. Supporting springs 32 are sleeved on both sides of the outer wall of the positioning bolt 31, and the two supporting springs 32 are distributed on both sides of the fixing block 3.

[0039] In use, the positioning bolts 31 connect the fixing block 3 to the hopper 2, thus fixing the hopper 2 to the frame 1. At the same time, the support springs 32 are distributed on both sides of the fixing block 3, providing elastic support for the hopper 2. When the hopper 2 is subjected to vibration, the support springs 32 can act as a buffer, reducing the impact of vibration on the frame 1 and other components, and making the vibration of the hopper 2 more stable.

[0040] To drive vibration, for example, such as Figure 6 As shown, the protrusion 43 adopts an arc shape design, the spacing between the protrusions 43 is greater than the thickness of the drive plate 14, the drive plate 14 is located between the extension plates 42, and the drive plate 14 is in contact with the outer wall of the extension plate 42.

[0041] In use, the arc-shaped protrusions 43 design can reduce the friction and impact when the drive plate 14 and the extension plate 42 come into contact, making the interaction between the two more gentle and reducing the wear rate of the components. The spacing between the protrusions 43 is greater than the thickness of the drive plate 14 and the drive plate 14 is located between the extension plates 42, ensuring that the drive plate 14 can smoothly contact the protrusions 43 and push the extension plate 42. The spring 41 is used for the extension plate 42 to swing, which facilitates the movement of the drive plate 14 between the protrusions 43, thereby driving the hopper 2 to vibrate.

[0042] In use, the wheat raw material to be processed is put into the hopper 2. The matching drive motor drives the support roller 11 to rotate, thereby driving the conveyor belt 12 to rotate at a constant speed. The drive plates 14 on both sides of the partition plate 13 move with the conveyor belt 12. When the drive plate 14 contacts the feeding plate 22 in the hopper 2, it pushes the feeding plate 22 and the rotating shaft 21 to rotate in a circle. The rotation angle is controlled by the distance between the adjacent drive plates 14. During the rotation of the feeding plate 22, the material between them is brought to the lower end of the rotating shaft 21. The material falls between the partition plates 13 of the conveyor belt 12 due to its own weight, realizing quantitative falling.

[0043] After the drive plate 14 moves with the conveyor belt 12 and passes through the through hole 25 of the hopper 2, it enters between the extension plates 42 and contacts the protrusions 43. Since the protrusions 43 are arc-shaped and the spacing is adapted to the thickness of the drive plate 14, when the drive plate 14 pushes the extension plate 42 through the protrusions 43, the spring 41 undergoes elastic deformation, causing the extension plate 42 to swing, which in turn causes the hopper 2 to vibrate. This vibration is transmitted to the inside of the hopper 2, which can prevent material from accumulating.

[0044] When the shaft 21 rotates, the friction ring 24 inside the collar 23 contacts the outer wall of the shaft 21 to generate damping, which prevents the feeding amount from suddenly increasing due to the excessive rotation speed of the shaft 21 caused by inertia.

[0045] The conveyor belt 12, carrying a fixed amount of material, operates continuously, conveying the material between the separators 13 at a uniform speed to the next process of the flour processing equipment.

[0046] It should be noted that this utility model is a uniform speed feeder for flour processing.
