Description

Technical Field

[0001] The utility model belongs to the technical field of food printing equipment, and in particular relates to a transmission component of a latte art machine. Background Art

[0002] Existing food printers, such as coffee latte machines and milk tea printers, almost all use the structural features of 3D printers, and basically use synchronous belts to transmit power. Therefore, the quality of the synchronous belt installation directly affects the quality of the product. For example, in the traditional installation method, some use cable ties to fix the ends of the conveyor belts. This installation method has low cost, but low degree of consistency, and the cable ties are prone to aging and breakage.

[0003] To this end, the applicant fixes the end of the synchronous belt by a compression assembly and a fastening bracket, which has high reliability, is not easy to fall off, and will not damage the end of the synchronous belt. The applicant has applied for a Chinese patent, patent number: 201821528534.1, and the name is: A synchronous belt end fastening device.

[0004] Although the applicant's prior application solved the problem that the synchronous belt head is easy to fall off and the cable tie is easy to age and break, it added a compression component, which made the structure complicated and increased the cost. In addition, it was not easy to operate due to the limited assembly space. Utility Model Content

[0005] The utility model aims to provide a transmission component for a drawing machine, which solves the technical problems in the prior art that a synchronous belt has a joint, a compression component needs to be used for tightening, the cost is high, and the operation is difficult.

[0006] In order to solve the above technical problems, the utility model adopts the following solutions:

[0007] The transmission assembly of the art drawing machine includes a motor, a synchronous belt and two synchronous pulleys. The synchronous pulleys are rotatably connected to the bracket. The synchronous belt is sleeved on the two synchronous pulleys and is in a tensioned state. The motor drives one of the synchronous pulleys to rotate. The synchronous belt is a full ring without any joints. An installation assembly for installing an ink cartridge is fixedly connected to the synchronous belt.

[0008] Chinese patent, patent number: 201821528534.1, title: A synchronous belt end fastening device, is the prior application of the applicant. In the actual production and assembly process, the product corresponding to this solution was found to be difficult to operate, and required many parts and high costs. Therefore, further research and development was carried out on this basis, resulting in the technical solution of this application.

[0009] In the present application, the synchronous belt is designed to be a full ring without joints, so it only needs to be put on two synchronous belt pulleys. It is easy to install and is particularly suitable for assembly in a small space. There is no need to separately design other components to fix the synchronous belt joints, thereby reducing costs.

[0010] The motor drives one of the synchronous pulleys to rotate, thereby driving the synchronous belt and the other synchronous pulley to rotate, so as to achieve the purpose of driving the mounting assembly and the ink cartridge on the mounting assembly to move together. Both the synchronous belt and the synchronous pulley are provided with synchronous teeth, so there will be no slipping and the transmission effect is good.

[0011] Further optimization, the motor is fixedly connected to the bracket, wherein one synchronous belt pulley is fixedly connected to the motor shaft, and the other synchronous belt pulley is directly rotationally connected to the bracket.

[0012] Further optimization, the motor and the bracket are detachably connected by bolts; a plurality of long waist-shaped holes for adjusting the installation position of the motor are opened on the bracket, and the bolts are screwed into the long waist-shaped holes to connect the motor and the bracket.

[0013] Before installing the synchronous belt, loosen the bolts, first move the motor along the length direction of the long waist-shaped hole, shorten the distance between the two synchronous pulleys, and make the distance between the two synchronous pulleys less than half the circumference of the annular synchronous belt. This makes it easy to put the synchronous belt on the two synchronous pulleys; then, move the motor in the reverse direction to increase the distance between the two synchronous pulleys, so that the synchronous belt is in a tensioned state, and then tighten the bolts. The operation is very convenient.

[0014] After the lace machine has been working for a long time, if the synchronous belt is deformed, in a loose state, and the transmission capacity decreases, loosen the bolts, move the motor along the length of the long waist-shaped hole, further increase the distance between the two synchronous belt wheels, make the synchronous belt in a tensioned state again, and then tighten the bolts. By opening the long waist-shaped hole, the adaptability of the entire device is improved, the service life of the synchronous belt is increased, and costs are saved.

[0015] Further optimization, the installation component is connected to the synchronous belt through a connecting block; the synchronous belt is clamped between the installation component and the connecting block.

[0016] Further optimization is that the side of the connection block that contacts the synchronous belt is provided with teeth, and is adapted to the synchronous teeth of the synchronous belt. By providing teeth on the connection block, friction is increased, and slippage between the synchronous belt and the mounting assembly is prevented when the synchronous belt rotates, thereby improving structural stability.

[0017] Further optimization, the installation assembly and the connecting block are fastened together by screws, which is convenient for disassembly, assembly and replacement.

[0018] Further optimization is that at least one guide rod is fixedly arranged on the bracket, and the mounting assembly is slidably sleeved on the guide rod. By setting the guide rod, the motor drives the mounting assembly and the ink cartridge to move along the guide rod together, preventing the ink cartridge from deflecting during the movement, thereby improving the structural stability and the drawing effect.

[0019] Compared with the prior art, the utility model has the following beneficial effects:

[0020] 1. The utility model designs the synchronous belt into a full ring shape without joints, so it only needs to be sleeved on two synchronous belt pulleys, which is easy to install and does not require other components for fixing the synchronous belt joints, thereby reducing costs.

[0021] 2. By opening a long waist-shaped hole, it is easy to install the synchronous belt and improve the adaptability of the entire device; it increases the service life of the synchronous belt and saves costs.

[0022] 3. By setting teeth on the connecting block, the friction force is increased to prevent the synchronous belt from slipping with the installation components when rotating, thereby improving the structural stability.

[0023] 4. By setting the guide rod, the motor drives the mounting assembly and the ink cartridge to move along the guide rod, preventing the ink cartridge from deflecting during the movement, thereby improving the structural stability and the drawing effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] like Figure 1-4As shown, the transmission assembly of the drawing machine includes a motor 1, a synchronous belt 4, a first synchronous pulley 2 and a second synchronous pulley 3. The synchronous belt 4 is sleeved on the two synchronous pulleys and is in a tensioned state. The synchronous belt 4 is a full ring without a joint; the synchronous belt is fixedly connected to a mounting assembly 6 for mounting an ink cartridge.

[0030] In this embodiment, the motor 1 is fixedly connected to the bracket 5, wherein the first synchronous pulley 2 is fixedly connected to the rotating shaft of the motor 1, and the second synchronous pulley 3 is directly rotatably connected to the bracket 5. In other embodiments, the motor and the first synchronous pulley can be driven by other components, such as gears.

[0031] By designing the synchronous belt into a full ring shape without joints, the synchronous belt only needs to be put on two synchronous belt pulleys, which is easy to install and does not require the design of other components to fix the synchronous belt joints, thereby reducing costs.

[0032] The motor drives the first synchronous pulley to rotate, thereby driving the synchronous belt and the second synchronous pulley to rotate, so as to achieve the purpose of driving the mounting assembly and the ink cartridge on the mounting assembly to move together. Both the synchronous belt and the synchronous pulley are provided with synchronous teeth, so there is no slippage and the transmission effect is good.

[0033] In this embodiment, the bracket 5 is provided with four first long waist-shaped holes 8 for adjusting the motor installation position. The motor body and the motor shaft are located on both sides of the bracket, that is, the bracket is provided with a second long waist-shaped hole 9 for the motor shaft to extend out. Bolts are screwed into the corresponding first long waist-shaped holes 8 to connect the motor 1 to the bracket 5, and the motor shaft is arranged through the second long waist-shaped holes 9, such as Figure 4 shown.

[0034] Before installing the synchronous belt, loosen the bolts and move the motor along the length direction of the first long waist-shaped hole first to shorten the distance between the two synchronous belt pulleys. This makes it easy to put the synchronous belt on the two synchronous belt pulleys. Then, move the motor in the reverse direction to increase the distance between the two synchronous belt pulleys, so that the synchronous belt is in a tensioned state, and then tighten the bolts. The operation is very convenient.

[0035] After the lace machine has been working for a long time, if the synchronous belt is deformed, in a loose state, and the transmission capacity decreases, loosen the bolts, move the motor along the length direction of the first long waist-shaped hole, further increase the distance between the two synchronous belt wheels, make the synchronous belt in a tensioned state again, and then tighten the bolts. By opening the long waist-shaped hole, the adaptability of the entire device is improved, the service life of the synchronous belt is increased, and costs are saved.

[0036] In other embodiments, the motor body and the motor shaft may be located on the same side of the bracket. The position between the motor and the bracket may be adjusted in other ways, such as setting a spring between the motor body and the bracket, and using the restoring force of the spring to automatically adjust the motor position to keep the synchronous belt in a tensioned state.

[0037] In this embodiment, if Figure 3 As shown, the mounting assembly 6 is connected to the synchronous belt 4 through the connecting block 7, and the mounting assembly 6 and the connecting block 7 are fastened and connected by screws. The synchronous belt 4 is clamped between the mounting assembly 6 through the connecting block 7, and the side of the connecting block 7 that contacts the synchronous belt 4 is provided with teeth, which can be adapted to the synchronous teeth of the synchronous belt. By providing teeth on the connecting block, the friction force is increased, the slippage between the synchronous belt and the mounting assembly is prevented when the synchronous belt rotates, and the structural stability is improved.

[0038] In other embodiments, the synchronous belt 4 and the mounting assembly 6 can be fixedly connected by other means, such as directly fixing the synchronous belt 4 and the mounting assembly 6 by screws, etc. Similarly, the mounting assembly 6 and the connecting block 7 can be connected by other means, such as riveting, plugging, etc.

[0039] In this embodiment, two parallel guide rods 10 are fixedly provided on the bracket, and the mounting assembly 6 is sleeved on the guide rods 10 via a sliding bearing. By providing the guide rods, the motor drives the mounting assembly and the ink cartridge to move along the guide rods together, preventing the ink cartridge from deflecting during the movement, thereby improving the structural stability and the drawing effect.

[0040] In other embodiments, the number of the guide rod may be one.
