Description

Technical Field

[0001] This utility model relates to the field of grain and oil processing technology, specifically to a grain and oil rolling mill roll that is easy to replace and maintain. Background Technology

[0002] The term "grain and oil" is closely related to our lives. Grain and oil can generally be divided into two main categories: grain products and oil products. Grain products include rice, corn, wheat, soybeans, and their processed products, while oil products include palm oil, soybean oil, rapeseed oil, cottonseed oil, corn oil, and other oils. In the processing of grain and oil, a rolling mill is required. The core component of the rolling mill is the rolling roller. Each rolling mill uses two rolling rollers. The rotation of the two rolling rollers crushes the oilseeds between the two rollers, thus pressing out the embryo. The rolling mill is widely used in the oil processing industry to crush crushed soybeans, sunflower seeds, rapeseed, and corn germ, etc.

[0003] Traditional grain and oil milling rolls require maintenance and cleaning during long-term, high-intensity operation. Sometimes, they need to be removed and replaced. However, the connection between the existing milling rolls and the milling machine is quite complicated, which makes the loading and unloading process of the milling rolls more troublesome and increases the cost of replacement and maintenance. Utility Model Content

[0004] The purpose of this invention is to provide a grain and oil milling roll that is easy to replace and maintain, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a grain and oil rolling mill roll that is easy to replace and maintain, comprising a box body, a support leg fixedly connected to the bottom of the box body, a feed inlet opened at the top of the box body, a discharge cylinder fixedly connected to the front of the box body near the bottom, an installation and disassembly mechanism provided on the left side of the box body near the top, and a drive mechanism provided on the right side of the box body near the top. The installation and disassembly mechanism includes a fixed frame, which is fixedly connected to the left side of the housing near the top. A bidirectional screw is rotatably connected to the front and rear sides of the fixed frame near the left side. A first motor is fixedly connected to the front of the fixed frame near the left side. A first hinge frame is symmetrically threaded onto the surface of the bidirectional screw. Limiting rods are fixedly connected to the front and rear sides of the fixed frame. A hinge rod is hinged within the first hinge frame. A second hinge frame is hinged to the other end of the hinge rod. A fixed block is fixedly connected to the right side of the second hinge frame. A slider is fixedly connected to the right side of the fixed block. A first rotating shaft is symmetrically arranged on the right side of the slider. A first slot is opened at the right end of the first rotating shaft, into which a rolling mill roller is inserted. A second rotating shaft is symmetrically arranged on the right side of the inner wall of the housing near the top. A second slot is opened at the left end of the second rotating shaft.

[0006] Preferably, the front end of the bidirectional screw is fixedly connected to the output end of the first motor, and the front of the first hinge frame is provided with a hole that matches the limiting rod. The first hinge frame is slidably connected to the surface of the limiting rod through the hole. The limiting rod limits the two first hinge frames so that the two first hinge frames can only move towards each other as the bidirectional screw rotates.

[0007] Preferably, the left side of the housing near the top has a groove that matches the slider, and the surface of the slider passes through and is slidably connected to the groove. The left side of the slider has a hole that matches the first rotating shaft, and the surface of the first rotating shaft passes through and is rotatably connected to the hole.

[0008] Preferably, the right side of the housing near the top has a hole that matches the second rotating shaft, and the surface of the second rotating shaft passes through and is rotatably connected to the hole, with the right end of the rolling roller inserted into the second slot.

[0009] Preferably, the drive mechanism includes a protective box, which is fixedly connected to the top right side of the box body. A third rotating shaft is symmetrically fixedly connected to the top right side of the box body. A second motor is fixedly connected to the bottom front side of the protective box. Worms are symmetrically rotatably connected to the bottom front and rear sides of the inner wall of the box body. A worm gear is fixedly connected to the right end of the surface of the third rotating shaft. A first gear is fixedly connected to the surface of the third rotating shaft near the right side of the box body. A second gear is fixedly connected to the surface of the second rotating shaft near the right side of the box body.

[0010] Preferably, the right side of the housing has holes on both the front and rear sides near the top, which match the third rotating shaft. The surface of the third rotating shaft passes through and is rotatably connected to the holes. The left end of the third rotating shaft is fixedly connected to the left side of the inner wall of the housing near the top.

[0011] Preferably, the output end of the second motor is fixedly connected to the front end of the worm gear on the front side of the inner wall of the housing. The worm gear meshes with the worm wheel, and the two worm gears are fixedly connected by a connecting shaft. The first gear meshes with the second gear, and the diameter of the first gear is larger than the diameter of the second gear. Therefore, the first gear drives the second gear to rotate slowly.

[0012] Compared with the prior art, this utility model provides a grain and oil milling roll that is easy to replace and maintain, and has the following beneficial effects: 1. This easy-to-replace and maintain grain and oil calendering roller, through the installation and disassembly mechanism, uses an external lifting device to fix the calendering roller during replacement, so that it will not fall down when disassembling. Then, the bolts connecting the first rotating shaft, the second rotating shaft and the calendering roller are removed. Then, the first motor is started to rotate the bidirectional screw. The rotation of the bidirectional screw will drive the two first hinge frames to move towards each other, thereby driving the left end of the hinge rod to move towards each other, and further causing the right end of the hinge rod to move to the left, thereby driving the fixing block and the slider to move to the left, so that the left end of the calendering roller is driven out of the first slot. Then, the calendering roller is removed from the box. This disassembly method makes it easier to remove the calendering roller from the box.

[0013] 2. This easy-to-replace and maintain grain and oil calendering roller, through a drive mechanism, starts a second motor to rotate two worm gears. Since the two worm gears are symmetrical front and back, their thread directions are opposite. Therefore, the operation of the second motor will cause the two worm wheels to rotate in opposite directions, thereby causing the two first gears of the two third rotating shafts to rotate in opposite directions. Through the cooperation of the second gears, the two second rotating shafts will rotate slowly, thereby causing the two calendering rollers to rotate slowly. The slow rotation of the calendering rollers can better crush the raw material fragments into thin sheets, increase the surface area of ​​the raw material, and thus improve the uniformity of mixing.

A second rotating shaft 514 is symmetrically arranged on the right side of the inner wall of the housing 1 near the top. A second slot 515 is opened at the left end of the second rotating shaft 514.

[0019] The front end of the bidirectional screw 52 is fixedly connected to the output end of the first motor 53. The front of the first hinge frame 54 has a hole that matches the limiting rod 55. The first hinge frame 54 is slidably connected to the surface of the limiting rod 55 through the hole.

[0022] Example 2 Please see Figure 6 Furthermore, based on Embodiment 1, a driving mechanism 6 is obtained.

[0023] The drive mechanism 6 includes a protective box 61, which is fixedly connected to the top right side of the box body 1. A third rotating shaft 62 is symmetrically fixedly connected to the top right side of the box body 1. A second motor 63 is fixedly connected to the front of the protective box 61 near the bottom. Worms 64 are symmetrically rotatably connected to the front and rear sides of the inner wall of the box body 1 near the bottom. A worm gear 65 is fixedly connected to the surface of the third rotating shaft 62 near the right end. A first gear 66 is fixedly connected to the surface of the third rotating shaft 62 near the right side of the box body 1. A second gear 67 is fixedly connected to the surface of the second rotating shaft 514 near the right side of the box body 1.

[0024] Holes matching the third rotating shaft 62 are provided on the front and rear sides of the right side of the housing 1 near the top. The surface of the third rotating shaft 62 is penetrated and rotatably connected to the hole. The left end of the third rotating shaft 62 is fixedly connected to the left side of the inner wall of the housing 1 near the top.

[0025] The output end of the second motor 63 is fixedly connected to the front end of the worm 64 on the front of the inner wall of the housing 1. The worm 64 meshes with the worm wheel 65. The two worms 64 are fixedly connected by a connecting shaft. The first gear 66 meshes with the second gear 67, and the diameter of the first gear 66 is larger than the diameter of the second gear 67. Therefore, the first gear 66 drives the second gear 67 to rotate slowly.

[0026] In actual operation, when this device is used and the blank rolling roll 513 is replaced, the blank rolling roll 513 is fixed by an external lifting device so that it will not fall down when it is disassembled. Then, the bolts connecting the first rotating shaft 511, the second rotating shaft 514 and the blank rolling roll 513 are removed. Then, the first motor 53 is started to rotate the bidirectional screw 52. The rotation of the bidirectional screw 52 will drive the two first hinge frames 54 to move towards each other, thereby driving the left end of the hinge rod 56 to move towards each other, and further driving the right end of the hinge rod 56 to move to the left, thereby driving the fixing block 58 and the slider 59 to move to the left, so that the left end of the blank rolling roll 513 leaves the first slot 512. Then, the blank rolling roll 513 is removed from the box 1. This disassembly method can more conveniently remove the blank rolling roll 513 from the box 1. The second motor 63 is started to rotate the two worm gears 64. Since the two worm gears 64 are symmetrical, their thread directions are opposite. Therefore, the operation of the second motor 63 will cause the two worm wheels 65 to rotate in opposite directions, which in turn causes the two first gears 66 of the two third shafts 62 to rotate in opposite directions. Through the engagement of the second gears 67, the two second shafts 514 will rotate slowly, which in turn causes the two rolling mill rolls 513 to rotate slowly. The slow rotation of the rolling mill rolls 513 can better crush the raw material fragments into thin sheets, increase the surface area of ​​the raw material, and thus improve the uniformity of mixing.
