Description
Technical Field
[0001] This utility model relates to the field of roasting machines, specifically to a seed roasting machine. Background Technology
[0002] A sesame seed roasting machine is a device used to roast sesame seeds during the production of sesame oil.
[0003] In existing technology, a seed roasting machine includes a rotary drive mechanism, a cylinder driven by the rotary drive mechanism, and blades installed inside the cylinder. The blades are spirally distributed along the inner wall of the cylinder, and the cylinder is a cylindrical structure with one end open and the other closed. A central hole is provided at the center of the closed end of the cylinder, and a central shaft passing through the central hole is provided inside the cylinder. Multiple agitator rods are fixedly connected along the central shaft, and the agitator rods are fixedly connected to the inner wall of the cylinder. A heating device is provided on the outside of the cylinder for heating the cylinder.
[0004] The rotation drive mechanism is located outside the cylinder and typically uses a synchronous belt drive. The rotation drive mechanism includes a motor, a driving synchronous pulley mounted on the motor's rotating terminals, a driven synchronous pulley mounted on the central shaft, and a synchronous belt meshing with the synchronous pulleys. The rotation drive mechanism drives the central shaft to rotate, thus rotating the entire cylinder.
[0005] The cylinder has a front cover at its open end, which consists of a front baffle connected to the cylinder's open end, a material inlet fixedly connected to the front baffle, and a slot between the front baffle and the material inlet. A rear baffle for supporting the cylinder is located on the outer side of its closed end, and both the front and rear baffles have annular grooves on their outer walls. A lower shell is located below the cylinder, and a support mechanism is located inside the lower shell. This mechanism includes a support frame fixed to the lower shell and multiple bearings that engage with the annular grooves of the front and rear baffles. The bearings, through the front and rear baffles, support the entire cylinder and limit its radial movement.
[0006] The cylinder has an upper shell at the top, and one end of the upper shell has a front plate that engages with a slot on the front baffle. The lower shell has a rear cover that engages with both the upper and lower shells at the end furthest from the cylinder. The bottom of the lower shell has multiple casters, and both sides of the lower shell have multiple ventilation holes.
[0007] In existing seed roasting machines, the blades are fixedly welded to the inner wall of the cylinder, which presents the following problems in actual use:
[0008] 1. Because the leaves are fixedly connected to the cylinder, and the sesame seeds are small, they tend to stick to the angle formed by the inner wall of the cylinder and the leaves during heating. This can cause some of the sesame seeds to burn, affecting the quality of the sesame oil.
[0009] 2. Because the blades are welded to the cylinder, installation and disassembly are inconvenient, which makes it difficult to replace the blades later. In addition, welding can easily produce harmful substances.
[0010] 3. After the sesame seeds are roasted, the drum needs to be cleaned. Because the blades and the inside of the roasting drum can easily form cleaning blind spots, it is not easy to clean and will affect the quality of the roasted sesame seeds in the later stages. Utility Model Content
[0011] The purpose of this invention is to provide a seed roasting machine that addresses the above-mentioned problems, solving the issues in the prior art where sesame seeds easily stick to the inner wall of the cylinder, causing some sesame seeds to be easily burnt, making them difficult to clean, and making it inconvenient to install the leaves.
[0012] To achieve the above objectives, this utility model discloses a seed roasting machine, which includes a cylinder, a central shaft connected to the closed end of the cylinder, a rotation drive mechanism for driving the cylinder to rotate, and blades installed inside the cylinder. The blades are rotatably mounted on the inner wall of the cylinder via pins. The seed roasting machine also includes a push mechanism for driving the blades to swing.
[0013] With the above structure, during the roasting process, when the cylinder stops rotating, the oscillating blades solve the problem that the cylinder is at a high temperature under the action of the heating device, and the small sesame seeds are easy to stick to the inner wall of the cylinder and the angle formed by the blades, which can easily cause some sesame seeds to be burnt, thus affecting the quality of sesame oil. Moreover, after roasting is completed, the oscillating blades can clean the blind spots formed by the blades and the inner wall of the roasting cylinder, avoiding the impact of improper cleaning on the quality of sesame seeds roasted later.
[0014] As a further improvement of this utility model, the pushing mechanism includes a linkage device, a push rod hinged to the linkage device, a push frame fixedly connected to one end of the push rod, and a push shaft cylinder fixedly connected to the end of the push frame away from the push rod; the push shaft cylinder is slidably sleeved on the central shaft, and the other end of the linkage device is connected to the extended end of the pin.
[0015] With the above structure, during the roasting process, by controlling the movement of the push shaft cylinder, the push frame and connecting rod device can be pushed. The connecting rod device controls the rotation of the blades, causing the sesame seeds stuck to the inner wall of the cylinder to fall off, thus preventing the sesame seeds from being roasted.
[0016] As a further improvement of this utility model, the outside of the push shaft cylinder is provided with a propulsion device for driving the push shaft cylinder to slide axially.
[0017] By adopting the above structure, the propulsion device controls the pushing mechanism, thereby controlling the rotation of the blades, which solves the problem of sesame seeds easily sticking to the inner wall of the cylinder.
[0018] As a further improvement of this utility model, the propulsion device includes a support and a connecting shaft rotatably mounted on the support. A rotating disk is installed at the outer end of the connecting shaft and a toothed wheel is installed at the inner end. Multiple annular grooves that cooperate with the toothed wheel are arranged at intervals along the axial direction on the outer periphery of the pushing shaft cylinder.
[0019] With the above structure, the rotating disk can be manually rotated, and the toothed dial can be used to push the mechanism forward. The swing angle of the blade can be arbitrarily controlled by the linkage device.
[0020] As a further improvement of this utility model, the pin body includes a connecting pin for fixed connection with the blade, a positioning pin for fixed connection with the connecting pin, and a threaded pin for fixed connection with the positioning pin. The positioning pin has a polygonal or toothed structure.
[0021] Using the above structure, the blades can be rotated along the inner wall of the cylinder by rotating the positioning pin through the connecting rod device, thereby precisely limiting the rotation angle of the blades.
[0022] As a further improvement of this utility model, the linkage device includes a first linkage that is connected to a positioning pin and a second linkage that is hinged to a push rod. The first linkage and the second linkage are hinged together, and the first linkage is provided with a non-circular connecting hole that is connected to the positioning pin.
[0023] The above structure results in a simple linkage device that is easy to implement and install.
[0024] As a further improvement of this utility model, the cylinder wall is provided with a through hole that cooperates with the connecting pin. The pin passes through the through hole and is connected to the outside of the cylinder by the connecting rod device. A limiting nut for limiting the radial movement of the blade is installed on the threaded pin.
[0025] By adopting the above structure, the driving mechanism is located on the outside of the cylinder, saving the space inside the cylinder used for roasting sesame seeds, and making installation more convenient; the limiting nut can limit the radial movement of the blades, making the structure more stable.
[0026] As a further improvement of this utility model, the rear baffle of the cylinder is a hollow outer ring body, which is sleeved on the outside of the cylinder body. The outer ring body is provided with multiple insertion holes for sliding insertion of the push rod.
[0027] With the above structure, the rear baffle not only serves as a load-bearing element, but also guides and fixes the push rod, making the structure of the pushing mechanism more stable.
[0028] In summary, the beneficial effects of this utility model are as follows: The rotatable blades not only solve the problem that sesame seeds easily stick to the angle between the inner wall of the cylinder and the blades under the heating device, leading to some seeds being burnt and affecting the quality of the sesame oil, but also facilitate cleaning the blind spots formed by the blades and the inner wall of the roasting cylinder after roasting. Furthermore, because the blades are rotatably mounted on the inner wall of the cylinder via pins, the problems of harmful substances being generated during welding of the blades to the cylinder and the inconvenience of blade installation or disassembly are solved.

[0040] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.
[0041] Reference Figures 1 to 7 In some embodiments of this utility model, the seed roasting machine includes a cylinder 2, a central shaft 21 connected to the closed end of the cylinder 2, a rotation drive mechanism 1 for driving the cylinder 2 to rotate, and blades 3 installed inside the cylinder 2. The blades 3 are rotatably mounted on the inner wall of the cylinder 2 via pins 31. The seed roasting machine also includes a pushing mechanism 6 for driving the blades 3 to swing. A heating device 4 is provided on the outside of the cylinder 2, and a support mechanism 5 is provided below the cylinder 2. The heating principle can be electromagnetic heating, resistance heating, gas heating, etc., preferably electromagnetic heating. The heating device 4 generally adopts a heating tube, heating plate, heating coil, etc., preferably a heating tube. Through the above improvements, when the cylinder 2 stops rotating, the oscillating blades 3 solve the problem that during the roasting process, because the sesame seeds are small and easily stick to the angle formed between the inner wall of the cylinder 2 and the blades 3 under the action of the heating device 4, some sesame seeds are easily roasted and thus affect the quality of sesame oil. Moreover, after the roasting is completed, the oscillating blades 3 can clean the blind spot formed between the blades 3 and the inner wall of the roasting cylinder, avoiding the impact of improper cleaning on the quality of the roasted sesame seeds in the later stages.
[0042] Reference Figures 4 to 6 In some embodiments of this utility model, the pushing mechanism 6 includes a connecting rod device 61, a push rod 62 hinged to the connecting rod device 61, a pushing frame 63 fixedly connected to one end of the push rod 62, and a pushing shaft cylinder 64 fixedly connected to the end of the pushing frame 63 away from the push rod 62; the pushing shaft cylinder 64 is slidably sleeved on the central shaft 21, and the other end of the connecting rod device 61 is connected to the extended end of the pin body 31. Through the above improvements, during the roasting process, when the cylinder 2 stops rotating, by controlling the pushing shaft cylinder 64 to slide axially, the pushing frame 63 and the connecting rod device 61 can be pushed. The connecting rod device 61 controls the blades 3 to swing, causing the sesame seeds stuck to the inner wall of the cylinder 2 to fall off, making it less likely for the sesame seeds to be burnt. Moreover, when cleaning the cylinder 2, it is easy to clean the blades 3 and the blind spots inside the roasting machine.
[0043] Reference Figure 6 In some embodiments of this utility model, a propulsion device 7 for driving the axial sliding of the push shaft cylinder 64 is provided on the outside of the push shaft cylinder 64. Through the above improvements, the propulsion device 7 controls the sliding of the push mechanism 6, thereby controlling the rotation of the blade 3, solving the problem that sesame seeds easily stick to the inner wall of the cylinder 2.
[0044] Reference Figures 2 to 4 and Figure 6 In some embodiments of this utility model, the propulsion device 7 includes a support 8 and a connecting shaft 72 rotatably mounted on the support 8. A rotating disk 73 is mounted on the outer end of the connecting shaft 72, and a toothed dial 71 is mounted on the inner end. Multiple annular grooves that mate with the toothed dial 71 are spaced axially along the outer periphery of the push shaft cylinder 64. The toothed dial 71 is a disc-shaped structure with multiple teeth evenly distributed on its outer periphery, which mate with the annular grooves on the push shaft cylinder 64. The support 8 is a telescopic device. When the cylinder 2 rotates, the toothed dial 71 is separated from the push shaft cylinder 64 by retracting the support 8. When the blade 3 needs to be rotated, the toothed dial 71 is brought into contact with the push shaft cylinder 64 by extending the support 8. Through the above improvements, manually rotating the rotating disk 73 causes the push mechanism 6 to slide forward under the action of the toothed dial 71, and the rotation angle of the blade 3 can be arbitrarily controlled under the action of the connecting rod device 61. In addition to being driven by a toothed dial, the propulsion device 7 can also be driven by a cylinder or a solenoid valve, preferably by a toothed dial.
[0045] Reference Figure 8 In some embodiments of this utility model, the pin body 31 includes a connecting pin 311 fixedly connected to the blade 3, a positioning pin 312 fixedly connected to the connecting pin 311, and a threaded pin 313 fixedly connected to the positioning pin 312. The positioning pin 312 has a polygonal or toothed structure. Through the above improvements, the connecting rod device 61 controls the rotation of the positioning pin 312, realizing the swing of the blade 3 along the inner wall of the cylinder 2, thereby arbitrarily limiting the swing angle of the blade 3.
[0046] Reference Figure 9 In some embodiments of this utility model, the linkage device 61 includes a first linkage 611 that is connected to the positioning pin 312 and a second linkage 612 that is hinged to the push rod 62. The first linkage 611 and the second linkage 612 are hinged together, and the first linkage 611 is provided with a non-circular connecting hole for connecting to the positioning pin 312. Through the above improvements, the linkage device 61 has a simple structure, is easy to implement, and is easy to install.
[0047] Referring to 10, in some embodiments of this utility model, the cylinder wall of the cylinder 2 is provided with a through hole 9 that cooperates with the connecting pin 311. The pin 31 passes through the through hole 9 and is connected to the connecting rod device 61 on the outside of the cylinder 2. A limiting nut 10 for limiting the radial movement of the blade 3 is installed on the threaded pin 313. Through the above improvements, the pushing mechanism 6 is set on the outside of the cylinder 2, saving the internal space of the cylinder 2 and making installation more convenient; the limiting nut 10 can limit the radial movement of the blade 3, making the structure more stable.
[0048] Reference Figures 4 to 6In some embodiments of this utility model, the rear baffle of the cylinder 2 is a hollow outer ring 11, which is sleeved on the outside of the cylinder 2. The outer ring 11 is provided with a plurality of through holes for sliding insertion of the push rod 62. Through the above improvements, in addition to bearing the load, the rear baffle can also guide and fix the push rod 62, making the structure of the pushing mechanism 6 more stable.
[0049] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of this utility model, and these improvements and substitutions should also be considered within the protection scope of this utility model.
