Description

Technical Field

[0001] This utility model relates to the field of material feeding technology, specifically a composite scale material feeding device. Background Technology

[0002] As a finished product silo, the main function of the composite weighing feeding equipment is to store the processed finished materials, ensure the orderly flow and temporary storage of materials during the production process, and accurately feed the materials into the composite weighing according to production needs. For reference, there is a finished product silo described in announcement number CN221395152U, which includes a silo body, a discharge port on the silo body, a dehumidification pipe on the silo body, a feeding hopper on the silo body, a drying component inside the silo body, and four support legs welded on the silo body. Two support legs on the same side are connected to two connecting plates, and the two closely spaced connecting plates are connected to a discharge component.

[0003] The aforementioned device assists in material feeding by pounding the discharge port. However, when a large amount of material is stored, the material at the bottom is subjected to the squeezing force of the material at the top, which increases the probability of the material at the bottom caking and affects the smoothness of material feeding. Pounding or stirring cannot solve the problem of the material at the bottom caking due to stress at the root. Utility Model Content

[0004] The purpose of this invention is to provide a composite weighing feeding device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A composite scale feeding device includes a feeding hopper suspended above the main body of the composite scale, and an electromagnetic valve is detachably connected to the lower surface of the feeding hopper;

[0007] The feeding hopper is fixedly connected to a partition mechanism, which includes a partition plate and an L-shaped plate. The partition plate is detachably connected to the inside of the feeding hopper. A fixing plate is fixedly connected to the upper surface of the partition plate, and several grooves are formed on the lower surface of the partition plate. The L-shaped plate is fixedly connected to the lower surface of the partition plate.

[0008] The outer surface of the feeding hopper is fixedly connected to a communication mechanism, which includes a sliding plate and an outer cylinder. The sliding plate is slidably connected to the lower surface of the partition, and the outer cylinder is fixedly connected to the lower surface of the sliding plate. A variable diameter inner rod is movably connected and embedded inside the outer cylinder.

[0009] The outer surface of the feeding hopper is provided with a feeding auxiliary mechanism, which includes a bearing and a mounting box. The bearing is fixedly connected to the inside of the feeding hopper, and an auger shaft is rotatably connected to the upper surface of the bearing. The mounting box is detachably connected to the lower surface of the partition, and one end of the bearing passes through the mounting box.

[0010] Furthermore, the feeding auxiliary mechanism further includes a first mounting base, a first bevel gear, and a second bevel gear. The first mounting base is fixedly connected to the outer surface of the feeding hopper. A motor is fixedly connected inside the first mounting base. A transmission shaft is fixedly connected to the output end of the motor. The first bevel gear is fixedly connected to one end of the transmission shaft. The second bevel gear is fixedly connected to the upper end of the auger shaft. The first bevel gear and the second bevel gear are meshed together.

[0011] Furthermore, the connecting mechanism further includes a second mounting base, a connecting rod, and an end cap. The second mounting base is fixedly connected to the outer surface of the feeding hopper. An electric push rod is fixedly connected inside the second mounting base. The connecting rod is fixedly connected to the lower end of the sliding plate. The output end of the electric push rod is fixedly connected to the connecting rod. The end cap is threadedly connected to the upper end of the outer cylinder.

[0012] Furthermore, the sliding plate and the L-shaped plate are matched, one end of the variable diameter inner rod is embedded with a steel ball for rotational connection, and the variable diameter inner rod passes through the end cap.

[0013] Furthermore, a spring is nested on the outer surface of the variable-diameter inner rod, with one end of the spring in contact with the variable-diameter inner rod and the other end of the spring in contact with the bottom surface of the outer cylinder.

[0014] Furthermore, the lower surface of the feeding hopper is fixedly connected to a connecting flange, and the feeding hopper can be detachably connected to the connecting flange in conjunction with a threaded assembly and a solenoid valve.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. The output end of the electric push rod, in conjunction with the connecting rod, pushes the sliding plate to slide. The sliding plate is slidably connected to the partition plate via the L-shaped plate, so that the opening of the partition plate is no longer obstructed by the sliding plate, thus enabling the connection between the two cavities. When the variable diameter inner rod passes through the groove, the steel ball strikes the partition plate under the influence of the elastic force, so that the force is transmitted to the material on the upper surface of the partition plate, which is conducive to the material on the partition plate sliding to the opening position. After the material in the lower cavity is discharged, the material in the upper cavity enters the lower cavity, realizing batch storage and avoiding the problem of too much raw material stored in the feeding hopper, which would cause the raw material at the bottom to be squeezed and caking by gravity, affecting the subsequent discharge.

[0018] 2. It can rotate the auger shaft, applying a downward force to the material, which is beneficial for the material to pass through the solenoid valve for feeding, and further allows the material to enter the composite weighing below. The shaft seat and the feeding hopper are fixedly connected, supporting the lower end of the auger shaft and making the auger shaft more stable when rotating. Attached Figure Description

Detailed Implementation

[0024] 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.

[0025] Please see Figure 1-4 In this embodiment of the utility model, a composite scale feeding device includes a feeding hopper 1 suspended above the main body of the composite scale, and an electromagnetic valve 2 is detachably connected to the lower surface of the feeding hopper 1.

[0026] The feeding hopper 1 is fixedly connected to a partition mechanism 4. The partition mechanism 4 includes a partition plate 401 and an L-shaped plate 404. The partition plate 401 is detachably connected to the inside of the feeding hopper 1. A fixing plate 402 is fixedly connected to the upper surface of the partition plate 401. Several grooves 403 are opened on the lower surface of the partition plate 401. The L-shaped plate 404 is fixedly connected to the lower surface of the partition plate 401.

[0027] The outer surface of the feeding hopper 1 is fixedly connected to a communication mechanism 5, which includes a sliding plate 503 and an outer cylinder 505. The sliding plate 503 is slidably connected to the lower surface of the partition plate 401, and the outer cylinder 505 is fixedly connected to the lower surface of the sliding plate 503. A variable diameter inner rod 506 is movably connected and embedded inside the outer cylinder 505.

[0028] The outer surface of the feeding hopper 1 is provided with a feeding auxiliary mechanism 3. The feeding auxiliary mechanism 3 includes a bearing 308 and a mounting box 305. The bearing 308 is fixedly connected to the inside of the feeding hopper 1. The upper surface of the bearing 308 is rotatably connected to an auger shaft 307. The mounting box 305 is detachably connected to the lower surface of the partition 401. One end of the bearing 308 passes through the mounting box 305.

[0029] Specifically, during use, the feeding hopper 1 is suspended on the frame above the composite scale. The raw material enters the interior of the feeding hopper 1 through external conveying equipment, such as a screw conveyor. At this time, the raw material is blocked by the separating mechanism 4 inside the feeding hopper 1, so that the raw material in the feeding hopper 1 is divided into two parts. This avoids the raw material stored in the feeding hopper 1 being too large, which would cause the raw material at the bottom to be squeezed and caking by gravity, affecting the subsequent feeding. The auger shaft 307 can rotate and apply a downward force to the material, which is conducive to the material passing through the solenoid valve 2. The connecting mechanism 5 controls the opening position of the separating mechanism 4, so that the separated cavities in the feeding hopper 1 are connected or separated.

[0030] Example 1

[0031] like Figure 1-4 As shown, the feeding auxiliary mechanism 3 also includes a first mounting base 301, a first bevel gear 304, and a second bevel gear 306. The first mounting base 301 is fixedly connected to the outer surface of the feeding hopper 1. A motor 302 is fixedly connected inside the first mounting base 301. A transmission shaft 303 is fixedly connected to the output end of the motor 302. The first bevel gear 304 is fixedly connected to one end of the transmission shaft 303. The second bevel gear 306 is fixedly connected to the upper end of the auger shaft 307. The first bevel gear 304 and the second bevel gear 306 are meshed together.

[0032] In this embodiment, the motor 302 is started, and the output end of the motor 302 drives the transmission shaft 303 to rotate. The transmission shaft 303, in conjunction with the first bevel gear 304, drives the second bevel gear 306 to rotate, which in turn causes the auger shaft 307 to rotate, applying a downward force to the material. This facilitates the material passing through the solenoid valve 2 for feeding and further allows the material to enter the composite weighing chamber below. The shaft seat 308 is fixedly connected to the feeding hopper 1, providing support for the lower end of the auger shaft 307 and making the rotation of the auger shaft 307 more stable.

[0033] like Figure 1-3 As shown, a connecting flange 101 is fixedly connected to the lower surface of the feeding hopper 1, a connecting lug 102 is fixedly connected to the outer surface of the feeding hopper 1, and bolts are threadedly connected to the outer surface of the fixing plate 402. The fixing plate 402 is detachably connected to the feeding hopper 1 by bolts.

[0034] In this embodiment, the feeding hopper 1 is detachably connected to the threaded assembly and the solenoid valve 2 via the connecting flange 101. The connecting lug 102 is used to install the hoisting assembly, which facilitates the user to install the feeding hopper 1. The dividing mechanism 4 is fixedly connected to the feeding hopper 1 via the fixing plate 402 and the bolt assembly, dividing the internal space of the feeding hopper 1 into two cavities.

[0035] Example 2

[0036] Based on Embodiment 1, in order to overcome the problem that it is inconvenient to block the separating mechanism 4 in Embodiment 1.

[0037] like Figure 1-4 As shown, the connecting mechanism 5 also includes a second mounting base 501, a connecting rod 504, and an end cap 508. The second mounting base 501 is fixedly connected to the outer surface of the feeding hopper 1. An electric push rod 502 is fixedly connected inside the second mounting base 501. The connecting rod 504 is fixedly connected to the lower end of the sliding plate 503. The output end of the electric push rod 502 is fixedly connected to the connecting rod 504. The end cap 508 is threadedly connected to the upper end of the outer cylinder 505.

[0038] In this embodiment, the electric push rod 502 is activated. The output end of the electric push rod 502, in conjunction with the connecting rod 504, pushes the sliding plate 503 to slide. The sliding plate 503 is slidably connected to the partition plate 401 through the L-shaped plate 404, so that the opening of the partition plate 401 is no longer blocked by the sliding plate 503, thus realizing the connection between the two cavities. After the material in the lower cavity is discharged, the material in the upper cavity enters the lower cavity, realizing batch storage and avoiding the problem that too much raw material is stored in the feeding hopper 1, which would cause the raw material at the bottom to be squeezed and caking by gravity, affecting the subsequent material discharge.

[0039] like Figure 1-4As shown, the sliding plate 503 and the L-shaped plate 404 are matched. One end of the variable diameter inner rod 506 is embedded and rotatably connected with a steel ball 507. The variable diameter inner rod 506 passes through the end cap 508. A spring is nested on the outer surface of the variable diameter inner rod 506. One end of the spring contacts the variable diameter inner rod 506, and the other end of the spring contacts the bottom surface of the outer cylinder 505.

[0040] In this embodiment, the partition 401 is inclined to facilitate the material to slide along the partition 401 to the opening position. When the sliding plate 503 moves, the outer cylinder 505 moves synchronously. The spring applies a force to the variable diameter inner rod 506, so that the steel ball 507 at the end of the variable diameter inner rod 506 contacts the lower surface of the partition 401. When the variable diameter inner rod 506 passes through the groove 403, the steel ball 507 strikes the partition 401 under the influence of the elastic force, so that the force is transmitted to the material on the upper surface of the partition 401, which is conducive to the material on the partition 401 sliding to the opening position.

[0041] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0042] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
