Description

Technical Field

[0001] This utility model relates to the field of sesame paste production technology, specifically a grinding device. Background Technology

[0002] In the production of sesame paste, grinding is the core process, mainly applied to roasted sesame seeds; However, when grinding sesame seeds, the grinding machine grinds the whole sesame seeds slowly. Grinding from large particles to powder requires a continuous and slow process. The sesame seeds are not easy to be finely crushed before entering the grinding disc, which prolongs the processing and grinding speed. In addition, the sesame seeds need to be guided into the grinding roller during grinding, and different particle sizes can easily hinder them from entering the grinding disc. Utility Model Content

[0003] The purpose of this invention is to provide a grinding device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A grinding device includes a grinding barrel, a feeding hopper at the top of the grinding barrel, a sealing cover at the top of the feeding hopper, an opening at the middle of the top of the grinding barrel, a grinding hopper at the bottom of the opening, a grinding component at the middle of the grinding hopper, an installation groove at the bottom of the outer wall of the grinding barrel, a driving component in the installation groove, a guide groove communicating with the inside of the grinding hopper at the middle of the grinding barrel, and a discharge pipe communicating with the guide groove at the middle of the outer wall of the grinding barrel. The grinding assembly includes a rotating shaft and a grinding cone disk located between the rotating shaft's outer wall and the grinding cone disk. The grinding cone disk is cone-shaped. The bottom of the outer wall of the grinding cone disk is close to the bottom of the inner wall of the abrasive hopper. The distance between the top of the outer wall of the grinding cone disk and the top of the inner wall of the abrasive hopper is greater than the distance between the bottom and the top. A boss is provided at the bottom of the rotating shaft's outer wall extending to the guide groove. A driven gear is provided at one end of the bottom of the rotating shaft extending to the mounting groove. The drive assembly includes a motor and a drive gear connected to the motor's output shaft, the drive gear meshing with a driven gear.

[0005] Furthermore, the bottom of the feed hopper is welded and fixed to the top of the grinding barrel, the internal space of the feed hopper is connected to the internal space of the grinding hopper, and is also connected to the internal space of the guide channel.

[0006] In this invention, the feed hopper guides the sesame particles to be ground into the grinding hopper, and the ground sesame powder enters the guide trough and is discharged and collected downwards under the action of gravity.

[0007] Specifically, the outer diameter of the sealing cover is adapted to the outer diameter of the feed hopper, a rubber pad is provided on the lower surface of the sealing cover, the top of the rubber pad is bonded and fixed to the bottom of the sealing cover, the outer diameter of the rubber pad is adapted to the inner diameter of the feed hopper, and a pull handle is provided at the center of the upper surface of the sealing cover.

[0008] In this invention, the sealing cap, in conjunction with the rubber gasket, is inserted into the top of the feed hopper. When sesame grinding is not required, the sealing cap blocks the top of the feed hopper, and the pull handle provides a point of leverage, making it convenient to open or install the sealing cap.

[0009] It should be noted that a fixing plate is provided at the top of the opening on the inner wall of the grinding barrel. The fixing plate is rotatably connected to the top of the rotating shaft, and the bottom of the rotating shaft is rotatably connected to the grinding barrel. The driven gear and the rotating shaft are integrally formed. The motor is fixedly connected to the grinding barrel by screws. The output shaft of the motor is fixedly connected to the bottom of the driving gear by a coupling. The top of the driving gear is rotatably connected to the grinding barrel by a connecting shaft.

[0010] In this invention, the fixed plate enhances the stability of the top rotation of the shaft. The motor is electrically connected to the outside via wires. The control switch on the outer wall of the grinding barrel controls the start of the motor. The rotation of the output shaft drives the coupling and the drive gear to rotate, and then, with the cooperation of the driven gear, the shaft and the grinding cone rotate.

[0011] Furthermore, the grinding cone and the rotating shaft are integrally formed, and the outer wall of the grinding cone is provided with a number of protrusions. The protrusions are distributed in an annular pattern at equal intervals. The boss and the rotating shaft are integrally formed, and an annular groove is provided at the bottom of the boss. An insert ring is provided at the middle position of the guide groove corresponding to the annular groove.

[0012] In this invention, multiple protrusions work together to fit closely to the inner wall of the grinding hopper. The distance between the top of the grinding hopper and the top of the grinding cone is large, which facilitates the concentrated entry of sesame particles. Under the action of gravity, the sesame particles enter the bottom position between the grinding hopper and the grinding cone, reducing the distance between them. This allows for the grinding and extrusion of sesame particles of different sizes. The insertion ring and the annular groove are inserted to increase the stability of the rotation of the protrusion and the guide groove.

[0013] It is worth adding that the upper surface of the grinding cone is provided with a conical top plate, and the conical top plate and the grinding cone are integrally formed. Scrapers are symmetrically provided on the outer wall of the rotating shaft near the conical top plate, and several ring-shaped blades are provided on the outer wall of the rotating shaft above the scrapers.

[0014] In this invention, a conical top plate is installed on a grinding cone disc, guiding the sesame seeds added in the feed hopper toward the edge. With the cooperation of a scraper, the sesame particles on the surface of the conical top plate are scraped, so that the sesame particles fall into the grinding hopper at the edge under the action of gravity. With the cooperation of multiple blades, the rotating shaft drives the blades to rotate, crushing and refining the sesame particles initially added inside, facilitating the grinding hopper and the grinding cone disc to squeeze and grind the sesame particles.

[0015] In addition, the discharge pipe is welded and fixed to the grinding barrel, and the inner port of the discharge pipe is higher than the outer port.

[0016] In this invention, the discharge pipe guides the sesame powder collected in the guide trough to be discharged, which helps to collect and process it centrally.

[0017] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model features a conical grinding hopper and a grinding cone. The top gap between the grinding hopper and the grinding cone is larger than the bottom gap, which facilitates the downward grinding of sesame particles under gravity. Multiple protrusions increase the friction with the inner wall of the grinding hopper, continuously and rapidly grinding the sesame particles. A motor provides power, and the drive gear drives the driven gear to rotate. The rotating shaft, with the cooperation of the boss and the guide groove, increases the stability of the grinding cone rotation. Two scrapers are in close contact with the conical top plate, and the cooperation of multiple blades further crushes and refines the sesame seeds initially added to the feed hopper, accelerating the grinding speed.

[0018] 2. This utility model, by setting a sealing cover with a rubber gasket, allows the sealing cover to be installed or removed from the feed hopper with the help of a pull handle, sealing the top of the feed hopper and preventing external dust particles from falling into the interior when not in use. The insertion ring and the annular groove are connected to each other, increasing the flexibility of the rotation of the boss and the guide groove. The installation of the fixing plate increases the stability of the rotation of the top of the rotating shaft. Attached Figure Description
