Abstract
Description
Technical Field
[0001] The utility model relates to the field of material turning, in particular to a material turning device of a baking machine. Background Art
[0002] The roasting machine is a kind of mechanical equipment that can evaporate the water in the material. It is currently widely used in various industries. Among them, it is widely used in the beverage industry, such as drying and frying tea raw materials.
[0003] After picking, tea leaves need to be dried and fried in a roasting machine so that the tea leaves can emit fragrance and be preserved for a long time after being dried and fried. Therefore, roasting machines play an important role in the frying of tea leaves. However, when common roasting machines on the market are used to roast tea leaves, the turning device used inside is mostly a single-axis structure. Its structure is to install multiple horizontal stirring teeth on the circumferential surface of the rotating shaft. When rotating, most of them rotate in one direction (such as the roasting machines of models 6cct-60 and 6cht-110). However, when the single axis rotates in a single direction for a long time, under the action of the inertia of the rotating shaft, the tea leaves will be adsorbed on one side of the vertical diameter inside the barrel (such as the roasting machine of model ph600pro). This situation can easily cause the tea leaves to only be able to move to the top of the tea leaves on the bottom layer of the barrel under the action of the stirring teeth when drying, and then repeat the operation of covering one layer with another layer, and the turning structure is relatively simple. Moreover, when the tea leaves are piled together, a large amount of heat will gather inside and cannot be dissipated, which can easily cause the inner layer of tea leaves to be over-dried. Utility Model Content
[0004] The main purpose of the utility model is to provide a material turning device for a baking machine, which can effectively solve the problems in the background technology.
[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0006] A material turning device of a baking machine comprises a first rod and a material barrel, wherein a coaxially arranged second rod is mounted on the first rod, and when working, the second rod rotates around the central axis of the first rod, and a first driven bevel gear and a second driven bevel gear are fixedly mounted on one end of the first rod and the second rod, respectively, and material scrapers are mounted on the circumferential surfaces of the first rod and the second rod;
[0007] An L-shaped bracket is fixedly installed at one end of the barrel, and a motor is fixedly installed at one end of the L-shaped bracket. An active bevel gear is fixedly installed on the output shaft of the motor. The active bevel gear is meshed with the first driven bevel gear and the second driven bevel gear. The active bevel gear drives the first driven bevel gear and the second driven bevel gear to rotate in different directions, and the material scrapers on the first rod and the second rod rotate in opposite directions, so as to achieve the purpose of stirring the material.
[0008] Furthermore, it also includes a base bracket, and the barrel is rotatably arranged on the base bracket.
[0009] Furthermore, the material scraper is located inside the barrel and is rotatable.
[0010] Furthermore, two L-shaped brackets are fixedly mounted on the circumferential surface shell of the motor, and the two L-shaped brackets can be combined into a U-shaped structure.
[0011] Furthermore, the first driven bevel gear and the second driven bevel gear are rotatably mounted between the two L-shaped brackets.
[0012] Furthermore, one end of the second rod is rotatably mounted on the L-shaped bracket.
[0013] Compared with the prior art, the utility model has the following beneficial effects:
[0014] Compared with the traditional single-axis material turning in a single direction for a long time, the utility model can drive the active bevel gear to drive the first driven bevel gear and the second driven bevel gear to rotate in different directions under the drive of the motor output shaft, so that the first rod and the second rod can drive the material scraper to rotate in the positive and negative directions inside the barrel, and under the action of the material scraper, the tea leaves can move back and forth in position, abandoning the situation that the traditional material turning device can only cover the tea leaves layer by layer.
[0015] Moreover, under the action of the material scraper, the tea leaves can be changed in position, so that the tea leaves will not be piled up for a long time, and a large amount of heat will not gather inside the tea leaves, which will cause the tea leaves to be over-dried.

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0022] Please refer to the figure, this embodiment provides a material turning device for a roasting machine, including a base bracket 1, vertical poles are fixedly installed on both sides of the base bracket 1, a rotating rod is rotatably installed on the inner side of the upper end of the pole, and the other end of the rotating rod is fixedly installed on the outer shell of the barrel 2 (the rotating rod is close to the opening of the barrel 2), and the other end of the barrel 2 is placed on the base bracket 1 to keep the barrel 2 in a horizontal state (specific reference is made to common roasting machines on the market, such as model Roast200-600). The inside of the barrel 2 is provided with a groove extending from one end to the inside near the other end, and the inside of the barrel 2 is used to place tea leaves that need to be dried. A baffle is fixedly installed on the upper end of the opening of the barrel 2, and an L-shaped feed port is installed on the baffle. A material plate is rotatably installed on the diameter edge of the baffle using a hinge. A support leg is rotatably mounted on the open end of the barrel 2, and a U-shaped frame is fixedly mounted on the other end. After the tea leaves are roasted, the barrel 2 is rotated upward on the top of the support leg to allow the tea leaves inside the barrel 2 to slide out of the barrel 2 (for details, please refer to the roasting machine model BD-01ET / WT).
[0023] An L-shaped bracket 21 is installed at one closed end of the barrel 2. The outer side of the L-shaped bracket 21 is fixedly installed on the end surface of the barrel 2. A rectangular structure is fixedly installed at one end of the L-shaped bracket 21. The center position of the intersection of the rectangular structures is on the same horizontal line as the axis of the barrel 2. A motor 3 is arranged at the other end of the L-shaped bracket 21. The outer shell of the motor 3 is fixedly installed on the L-shaped bracket 21. Another L-shaped bracket 21 is installed on the motor 3. The two L-shaped brackets 21 are symmetrically arranged with the axis of the motor 3 as the symmetry axis. Figure 1 shown.
[0024] The output shaft of the motor 3 is fixedly mounted with a driving bevel gear 31, and the output shaft of the motor 3 can rotate synchronously with the driving bevel gear 31 (wherein the motor 3 is a forward and reverse motor, the specific model is 200wd-M60010-72v, and can rotate clockwise and counterclockwise). The driving bevel gear 31 is meshed with two driven bevel gears, refer to Figure 3 In order to distinguish them, they are named as the first driven bevel gear 4 and the second driven bevel gear 6, and the first driven bevel gear 4 and the second driven bevel gear 6 are located between the two L-shaped brackets 21. Figure 2 When the active bevel gear 31 rotates, it can drive the first driven bevel gear 4 and the second driven bevel gear 6 to rotate in different directions.
[0025] A first rod 5 is fixedly mounted on the first driven bevel gear 4 close to the material barrel 2. The first rod 5 passes through the rectangular structure on the L-shaped bracket 21 and extends to the interior of the material barrel 2, but its length is only half of the interior of the material barrel 2. A bearing is mounted on the circumferential surface of the first rod 5. The bearing is rotatably mounted on the rectangular structure of the L-shaped bracket 21 to allow the first rod 5 to rotate, thereby preventing the first rod 5 from being unable to rotate or getting stuck due to high friction when rotating.
[0026] The second driven bevel gear 6 is fixedly mounted with a second rod 7, one end of which is rotatably mounted on the rectangular structure of the L-shaped bracket 21. The second rod 7 passes through the first rod 5 and extends to the opening of the barrel 2. The first rod 5 and the second rod 7 are coaxially arranged, and the second rod 7 can rotate on the first rod 5.
[0027] Furthermore, when the first driven bevel gear 4 and the second driven bevel gear 6 rotate, they can synchronously rotate with the corresponding first rod 5 or second rod 7 , but the rotation directions of the first rod 5 and the second rod 7 are opposite.
[0028] Connecting rods evenly distributed are fixedly installed on the circumferential surfaces of the first rod 5 and the second rod 7, and a material scraper 8 is fixedly installed on the other end of the connecting rod. The material scrapers 8 on the first rod 5 and the second rod 7 are staggered and rotate in opposite directions. The material scraper 8 connected to the first rod 5 is slightly higher at one end close to the motor 3 and slightly lower at the other end, while the material scraper 8 on the second rod 7 is opposite to this. Therefore, when the first rod 5 and the second rod 7 rotate, the material scraper 8 on the first rod 5 can deliver the tea leaves to the position of the second rod 7, and the material scraper 8 on the second rod 7 can deliver the tea leaves to the position of the first rod 5, so that the tea leaves can move back and forth, avoiding the tea leaves from being in one position for a long time, and avoiding the tea leaves from accumulating for a long time, which causes the internal heat to be unable to be discharged.
[0029] Its working principle is as follows: when in use, tea leaves are introduced into the interior of the barrel 2, and the motor 3 is started. Under the action of the output shaft of the motor 3, the active bevel gear 31 is driven to rotate, and the active bevel gear 31 drives the first driven bevel gear 4 and the second driven bevel gear 6 to rotate in different directions.
[0030] When the first driven bevel gear 4 and the second driven bevel gear 6 rotate, they can drive the corresponding first rod 5 and second rod 7 to move synchronously. Therefore, the connected material scraper 8 can rotate under the drive of the first rod 5 and the second rod 7. Under the action of the material scraper 8, the tea leaves can move back and forth horizontally without interruption, changing the situation that the traditional tea leaves can only be covered layer by layer during drying. In addition, because the material scrapers 8 on the first rod 5 and the second rod 7 are staggered, the tea leaves can be exchanged under the action of the material scraper 8, so that the tea leaves will not be piled up for a long time, and a large amount of heat is avoided inside the tea leaves, which causes the tea leaves to be over-dried.
[0031] The above shows and describes the basic principles and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which shall fall within the scope of the utility model to be protected. The scope of protection of the utility model shall be determined by the attached claims and their equivalents.
