Description

Technical Field

[0001] This utility model relates to the field of sesame processing technology, and in particular to a sesame quantitative addition device. Background Technology

[0002] In the production of sesame products, whole or partially processed sesame seeds are typically added to the raw materials in precise quantities to enhance the flavor, texture, and nutritional value of the product. The precision and stability of this addition process directly affect the uniformity of the final product quality.

[0003] Currently, common quantitative addition methods in production mainly include manual weighing and simple mechanical feeding devices. Manual addition is inefficient, labor-intensive, and relies entirely on the operator's experience, making it prone to fluctuations in the addition amount due to human factors, and difficult to guarantee the consistency of batch products. Existing mechanical feeding devices, such as screw feeders or simple gate-type feeders, while reducing the labor burden to some extent, still have significant drawbacks: screw feeders easily crush sesame seeds, affecting product appearance; gate-type feeders struggle to achieve high-precision intermittent quantitative control, are prone to blockages or leaks, resulting in inaccurate and unstable feeding amounts.

[0004] To address this, we designed a sesame quantitative addition device. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this utility model discloses a sesame quantitative addition device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A sesame quantitative addition device, comprising:

[0008] Mounting rack;

[0009] A horizontal sleeve is fixedly connected to the inner side of the mounting frame, and its top and bottom are respectively provided with a feed inlet and a discharge outlet;

[0010] A metering shaft is rotatably mounted in the inner cavity of the horizontal sleeve, and at least three metering cavities are evenly arranged around its circumference.

[0011] A drive motor is located at one end of the mounting bracket and is used to intermittently drive the quantitative shaft to rotate;

[0012] Wherein, the central angle A between the same side of the feed inlet and the discharge outlet is not less than the central angle B at the opening of the metering cavity, and the central angle C of the feed inlet and the central angle D of the discharge outlet are both not greater than the central angle B at the opening of the metering cavity.

[0013] Furthermore, a storage hopper is provided above the feed inlet, and its discharge port is connected to the feed inlet.

[0014] Furthermore, the mounting frame is provided with an upper support at the top, and the upper end of the upper support is connected to the side of the storage hopper to assist in supporting the storage hopper.

[0015] Furthermore, a material collection hopper is installed at the bottom of the mounting frame via a lower support for collecting the material discharged from the outlet.

[0016] Furthermore, there is an observation gap between the hopper and the horizontal sleeve.

[0017] Furthermore, a detection component is provided at the end of the mounting bracket away from the drive motor for detecting the rotation angle of the quantitative shaft.

[0018] Furthermore, the detection component includes:

[0019] A photoelectric switch is disposed above one end of the mounting bracket;

[0020] A rotating shaft is rotatably connected to one end of the mounting bracket and is coaxially fixed to the quantitative shaft.

[0021] The test piece is coaxially mounted on the outer end of the rotating shaft, and its circumference is provided with test protrusions at uniform intervals. The number of test protrusions is the same as the number of quantitative cavities.

[0022] Furthermore, the measured protrusion is provided in a one-to-one correspondence with the partition between the middle of the quantitative cavity opening or between adjacent quantitative cavities.

[0023] Compared with the prior art, the beneficial effects of this utility model are:

[0024] 1. By using the angular relationship between the feed inlet, discharge outlet and the opening of the metering chamber, it is ensured that at any given time during the rotation process, only one metering chamber is connected to the feed inlet or discharge outlet, which effectively prevents leakage and cross-contamination of materials during the transfer process, thereby ensuring that the volume of each added material is constant and the metering accuracy is high.

[0025] 2. Due to the design of the horizontal sleeve, metering shaft, and drive motor, the mechanical structure is simple, with few parts, making it easy to assemble and maintain. The rotational motion of the metering shaft is smooth and reliable, with a low failure rate, making it very suitable for long-term stable operation in continuous production environments such as food processing.

[0026] 3. By setting up a detection assembly consisting of a photoelectric switch, a rotating shaft, and a test piece with a test protrusion, the rotation angle position of the quantitative shaft can be fed back in real time and accurately. In conjunction with the control system, the precise start and stop of the drive motor can be achieved, so that the quantitative cavity can be accurately aligned with the feeding and work station, realizing automated quantitative addition and reducing the reliance on manual operation.

[0027] 4. The device is equipped with a storage hopper for continuous feeding, and a collection hopper for easy collection and guiding of material out. The observation gap between the collection hopper and the horizontal sleeve allows operators to visually monitor the material feeding status and promptly identify and resolve problems. The overall layout of the device is reasonable and easily integrated into existing sesame processing production lines. Attached Figure Description

[0033] The present invention will be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention.

[0034] Example 1, in conjunction with Appendix Figure 1-4 A sesame quantitative addition device comprises three main parts: a mounting frame 1, a quantitative conveying mechanism, and a driving and detection mechanism.

[0035] The mounting frame 1 is the main support for the entire device, and is preferably made of welded or bolted profiles, with sufficient structural strength and stability.

[0036] The quantitative conveying mechanism includes a horizontal sleeve 2 and a quantitative shaft 3. The horizontal sleeve 2 is fixedly connected to the inner side of the mounting frame 1 by welding or bolting. The top of the horizontal sleeve 2 has a feed inlet 21 and the bottom has a discharge outlet 22.

[0037] The metering shaft 3 is rotatably disposed within the inner cavity of the horizontal sleeve 2. At least three metering cavities 31 are evenly distributed along the circumference of the metering shaft 3. Preferably, the number of metering cavities 31 is three or four.

[0038] In one possible implementation, the number of metering cavities 31 is three, and the metering shaft 3 includes a Y-shaped structure formed by welding three rectangular plates. Circular plates are welded to both ends of the Y-shaped structure, and a shaft end coaxial with it is integrally formed on the outer surface of the circular plate. The shaft end is rotatably connected to the horizontal sleeve 2 through a bearing.

[0039] In another possible implementation, the number of metering chambers 31 is four, and the metering shaft 3 includes a cross-shaped structure formed by welding three rectangular plates. Circular plates are welded to both ends of the cross-shaped structure. A shaft end coaxial with the outer surface of the circular plate is integrally formed thereon. The shaft end is rotatably connected to the horizontal sleeve 2 through a bearing.

[0040] The driving and detection mechanism includes a drive motor 4 and a detection component 9. The drive motor 4 is fixedly mounted on one end of the mounting bracket 1 via a motor mount, and its output shaft is directly connected to one end of the quantitative shaft 3 via a coupling, which is used to provide power to drive the quantitative shaft 3 to perform intermittent rotational motion.

[0041] Specifically, when there are three quantitative chambers 31, the drive motor 4 drives the quantitative shaft 3 to rotate by an angle of 120 degrees each time; when there are four quantitative chambers 31, the drive motor 4 drives the quantitative shaft 3 to rotate by an angle of 90 degrees each time.

[0042] The detection component 9 is located at the other end of the mounting frame 1 away from the drive motor 4. It is used to detect the rotation angle of the quantitative shaft 3 in real time, so as to cooperate with the control unit (not shown in the figure) to accurately control the start and stop position of the quantitative shaft 3 and ensure the accuracy of the alignment between the quantitative cavity 31 and the feed port 21 or the discharge port 22.

[0043] Specifically, the central angle A between the sides of the inlet 21 and the outlet 22 on the same side is not less than the central angle B at the opening of a single metering cavity 31. Simultaneously, the central angle C of the inlet 21 and the central angle D of the outlet 22 are both not greater than the central angle B at the opening of the metering cavity 31. This angle setting ensures that during the rotation of the metering shaft 3, at any given time, at most one metering cavity 31 is simultaneously connected to both the inlet 21 and the outlet 22, effectively preventing material "cross-contamination" during transport and guaranteeing the accuracy of metered addition.

[0044] Furthermore, in order to achieve continuous feeding, a storage hopper 5 is installed above the feed inlet 21 of the horizontal sleeve 2. The discharge port of the storage hopper 5 is connected to the feed inlet 21 of the horizontal sleeve 2 via a flange or flexible connection, thereby continuously supplying the sesame material to be added to the metering chamber 31.

[0045] Furthermore, in order to enhance the stability of the storage hopper 5, two upper supports 6 are provided on the top of the mounting frame 1. The upper ends of the two upper supports 6 are connected to the opposite sides of the storage hopper 5, which plays an auxiliary supporting role for the storage hopper 5.

[0046] Furthermore, in order to centrally add materials, a material collection hopper 8 is installed at the bottom of the mounting frame 1 via a lower bracket 7. The upper opening of the material collection hopper 8 is directly opposite the discharge port 22 of the horizontal sleeve 2, and is used to receive and guide the sesame seeds falling from the metering chamber 31.

[0047] Preferably, a certain observation gap is left between the bottom of the material hopper 8 and the horizontal sleeve 2, so that the operator can intuitively observe whether the material feeding is smooth.

[0048] Specifically, the size of the upper port of the hopper 8 is larger than the size of the discharge port 22 of the horizontal sleeve 2, to ensure that the sesame material discharged from the discharge port 22 will not leak to the outside of the hopper 8.

[0049] A preferred embodiment of the detection component 9 includes a photoelectric switch 91, a rotating shaft 92, and a test piece 93. The rotating shaft 92 is rotatably connected to the end of the mounting frame 1 via a bearing and is coaxially fixedly connected to the quantitative shaft 3. The test piece 93 is coaxially mounted on the outer end of the rotating shaft 92. At least three test protrusions 931 are evenly spaced on the circumferential side of the test piece 93. The specific number of these protrusions is the same as the number of quantitative cavities 31. The photoelectric switch 91 is fixedly mounted on the mounting frame 1, with its sensing head facing the circumferential surface of the test piece 93.

[0050] When the quantitative shaft 3 rotates, it drives the measured object 93 to rotate synchronously. The measured protrusion 931 passes through the sensing area of ​​the photoelectric switch 91 in sequence, generating pulse signals. The control unit can accurately determine the real-time angular position of the quantitative shaft 3 by counting these pulse signals.

[0051] Preferably, the measured protrusion 931 is provided in a one-to-one correspondence with the partition between the middle of the opening of the metering cavity 31 or between adjacent metering cavities 31. For example, when the photoelectric switch 91 detects a measured protrusion 931, it means that a metering cavity 31 has just rotated to the optimal position that is completely aligned with the feed inlet 21 or the discharge outlet 22, thereby sending a signal to control the drive motor 4 to stop rotating, achieving precise positioning.

[0052] The working principle is as follows:

[0053] Initially, a metering chamber 31 rotates to align with the inlet 21, and sesame material is fed into this chamber from the storage hopper 5 through the inlet 21. Then, the drive motor 4 starts, rotating the metering shaft 3 at a certain angle. During rotation, the metering chamber 31, now full, disengages from the inlet 21 and deflects towards the outlet 22; simultaneously, the next empty metering chamber 31 rotates to below the inlet 21 to receive material, while the previously filled metering chamber 31 rotates to connect with the outlet 22. The material in this chamber 31 is discharged through the outlet 22 under gravity, falling into the collection hopper 8, completing one metering addition operation. This cycle repeats continuously, achieving intermittent metering addition.

It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that this utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
