Description

Technical Field

[0001] This invention relates to the field of servo motor technology, specifically a servo motor and dough kneading machine that employs a hollow shaft with integrated cooling channels. Background Technology

[0002] Hollow shaft integrated cooling channels refer to the specific flow channel shape set inside the hollow shaft, allowing the cooling medium to flow in the channel and carry away the heat generated during motor operation, thereby reducing the motor temperature and improving the motor's performance and reliability. Servo motors using this type of hollow shaft integrated cooling channel in dough kneading machines can better cope with the heat generated by the motor during long-term operation during dough kneading, ensuring stable motor operation, extending the motor's service life, and thus improving the overall performance and working efficiency of the dough kneading machine.

[0003] When traditional dough kneading machines are working, the flour on the equipment will generate a lot of fine dust. The dust floating in the air can easily adhere to the surface of the servo motor. If flour particles accumulate in the gaps of the heat dissipation fins of the servo motor or the ventilation holes of the outer shell, they will form a "heat insulation layer", which will hinder the transfer of heat from the inside of the motor to the outside, accelerate the aging of the motor insulation layer, and have poor practicality. At the same time, the flour particles accumulated in the gaps of the heat dissipation fins are not easy to clean, resulting in poor flexibility.

[0004] During operation, servo motors generate extra heat due to their high-precision control characteristics. They are usually cooled by conducting heat through an aluminum alloy shell and using dense heat dissipation fins. Therefore, if a servo motor runs for a long time or in a high-temperature environment, poor heat dissipation can easily cause motor damage, leading to winding insulation aging, short circuits, and other faults.

[0005] When installing a servo motor, it is usually fixed directly with bolts or with the help of a motor bracket. However, when the mounting holes of the servo motor do not correspond to the pre-drilled holes on the dough kneading machine, repeated drilling is required, which is inefficient. At the same time, when using a bracket, the bracket is directly fixed to the dough kneading machine with bolts, and the bracket and the motor are connected by bolts. Therefore, when the motor is damaged and needs to be repaired, the bolts need to be removed to remove the motor from the bracket, which requires repeated turning of the bolts, resulting in low efficiency.

Detailed Implementation

[0036] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0037] like Figures 1-3 , Figure 5 , Figure 6 and Figure 9As shown, the present invention discloses a servo motor and dough kneading machine with a hollow shaft integrated cooling channel, comprising a servo motor body 1, an assembly structure 2 mounted on the servo motor body 1, an adjustment structure 3 mounted on the assembly structure 2, and a mounting structure 4 mounted on the adjustment structure 3. The assembly structure 2 includes a front cover 204, which is fixedly connected to the servo motor body 1. A rear cover 201 is fixedly connected to the servo motor body 1, and a compiler 202 is fixedly connected to the rear cover 201. Wires 203 are fixedly connected to both the rear cover 201 and the compiler 202. The compiler 202 is mounted on the end of the servo motor body 1 through the rear cover 201. The compiler 202 enables precise control of the operating state of the servo motor body 1.

[0038] Specifically, such as Figures 1-3 , Figure 5 and Figure 6 As shown, when installing the servo motor body 1, if it is necessary to directly fix the servo motor body 1 to the dough kneading machine, in order to solve the problem of the deviation between the reserved hole on the servo motor body 1 and the hole on the dough kneading machine, the adjustment structure 3 includes a mounting hole 301 and an adjustment groove 302 communicating with the mounting hole 301. The front cover 204 is provided with the mounting hole 301 and the adjustment groove 302. The front cover 204 is provided with a cover plate 303. The cover plate 303 is provided with a sliding groove 304. A bolt 305 passes through the mounting hole 301. The bolt 305 is slidably connected to the adjustment groove 302 and the sliding groove 304. The end of the bolt 305 abuts against the cover plate 303. The front cover 204 and the cover plate 303 are fixedly connected by screws 306. The front cover 204, the cover plate 303 and the rotating seat are all connected together. The four bolts 305 are fixedly connected by bolts 305. Simply fix the cover plate 303 to the front cover 204 on the servo motor body 1 with screws 306. Then, pass the four bolts 305 through the four mounting holes 301 respectively. Next, move the ends of the bolts 305 into the adjusting groove 302. At this time, the ends of the bolts 305 are engaged between the front cover 204 and the cover plate 303, preventing the bolts 305 from falling off. Then, the bolts 305 can be slid freely along the sliding groove 304. Repeat the same operation and move the other three bolts 305 until the four bolts 305 are moved to correspond to the holes on the dough kneading machine. Then, the servo motor body 1 can be installed. It is highly flexible and avoids the problem of having to re-drill holes when the holes do not match.

[0039] Specifically, such as Figures 1-5As shown, when the servo motor body 1 needs to be mounted with the aid of a bracket, the mounting structure 4 includes a mounting base 401 and a slide rod 402 fixedly connected to the mounting base 401. The mounting base 401 is provided on the side of the cover plate 303. A slider 403 is slidably connected to the slide rod 402. The slider 403 is slidably connected to the mounting base 401. A tension spring 404 is fixedly connected between the slider 403 and the mounting base 401. A rotating seat 405 is rotatably connected between the two sliders 403. The rotating seat 405 is locked to the front end cover 204 of the servo motor body 1 with bolts 305. A knob 407 is rotatably connected to the mounting base 401. A limit block 406 is slidably connected to the mounting base 401. The limit block 406 is threadedly connected to the knob 407. The inclined surface at the bottom of the limit block 406 is slidably engaged with the slider 403. Simply fix the mounting base 401 onto the dough kneading machine; the operation is simple. When the servo motor body 1 is damaged and needs repair, to avoid the need to disassemble the servo motor body 1 for repair, which would affect the repair efficiency, simply rotate the servo motor body 1 90 degrees. This facilitates the disassembly and repair of the servo motor body 1. At this time, simply turn the knob 407 with a hex wrench. The knob 407 drives the limit block 406 to move upward until the limit block 406 no longer blocks the slider 403. Then pull the servo motor body 1 outward. At this time, the rotating base 405 drives the two sliders 403 to slide along the slide rod 402 and stretches the tension spring 404 until the end face of the mounting base 401 no longer blocks the rotation of the rotating base 405. At this time, the servo motor body 1 can be rotated 90 degrees for repair. The operation is simple and improves the repair efficiency.

[0040] Specifically, such as Figures 1-3 and Figures 5-11As shown, before installing the servo motor body 1 onto the dough kneading machine, a dust cover 501 needs to be installed on the servo motor body 1. A dustproof structure 5 is connected to the servo motor body 1. The dustproof structure 5 includes a dust cover 501 and a retaining strip 502 fixedly connected to the dust cover 501. The dust cover 501 abuts against the front end cover 204. A retaining sleeve 503 is fixedly connected to the front end cover 204. The retaining strip 502 and the retaining sleeve 503 engage with each other. Two rubber rings 504 are fixedly connected to the dust cover 501. The rubber rings 504 provide a good sealing effect. The dust cover 501 has a wire 203 running through it. Simply pass the two wires 203 through the two rubber rings 504 on the dust cover 501, and then connect the terminal block to the wire 203. Next, align the two clips 502 on the dust cover 501 with the two retainers 503 on the servo motor body 1, and press the dust cover 501 down so that the two clips 502 are engaged in the two retainers 503 respectively. At this time, the installation of the dust cover 501 is completed. The dust cover 501 effectively prevents flour dust from directly adhering to the heat dissipation fins of the servo motor body 1, improves the heat dissipation effect of the servo motor body 1, and is easy to clean and highly flexible.

[0041] Specifically, such as Figure 1 and Figures 6-11 As shown, to improve the heat dissipation of the servo motor body 1 during operation, a heat dissipation structure 6 is connected to the dust cover 501. The heat dissipation structure 6 includes a mounting frame 601 and a DC motor 602 fixedly connected to the mounting frame 601. The output shaft of the DC motor 602 is rotatably connected to the mounting frame 601, and a fan blade 603 is fixedly connected to the output shaft of the DC motor 602. At this time, the DC motor 602 mounted on the mounting frame 601 starts to run, and the output shaft of the DC motor 602 drives the fan blade 603 to rotate. The fan blade 603 is fixedly connected to the dust cover 501. Multiple guide strips 605 are fixedly connected to the inner side of the dust cover 501, and multiple air holes 606 are opened on the dust cover 501. When the fan blades 603 rotate, they blow air into the servo motor body 1, which achieves a good heat dissipation effect. At the same time, since multiple guide strips 605 are provided on the inner side of the dust cover 501, the blown air flows along the gap between two guide strips 605 and is blown out from the air hole 606 at the other end of the dust cover 501, effectively guiding the air flow and enhancing the heat dissipation effect. Meanwhile, the fan mesh 604 at the outer end of the dust cover 501 provides a protective effect.

[0042] Specifically, such as Figure 1 , Figure 2 and Figures 5-11As shown, during the rotation of the fan blade 603 driven by the DC motor 602, a filter structure 7 is provided on the dust cover 501. The filter structure 7 includes a slide 701 and a slide plate 702 slidably connected to the slide 701. The slide 701 is fixedly connected to the dust cover 501, and the slide plate 702 is slidably connected to the dust cover 501. A filter screen 703 is engaged on the slide plate 702, and the filter screen 703 effectively filters the flour dust mixed in the air. A rubber strip 704 is fixedly connected to the slide 701, and the rubber strip 704 is slidably connected to both the slide plate 702 and the filter screen 703. A bottom cover 705 is slidably connected to the bottom of the dust cover 501, and two guide rods 706 are fixedly connected to the ends of the dust cover 501. The bottom cover 705 is connected to the guide rods. The guide rods 706 are slidably connected, and a nut 707 is threaded onto the guide rods 706. The nut 707 abuts against the bottom cover 705, preventing flour dust from being blown towards the servo motor body 1 by the fan blades 603. When it is necessary to clean the filter screen 703, simply pull the slide plate 702 outward. The slide plate 702 drives the filter screen 703 to slide outward. Since the rubber strip 704 installed on the slide block 701 has a "U" shaped structure, the rubber strip 704 effectively scrapes off the flour particles attached to both sides of the filter screen 703 during the sliding process. The scraped flour particles fall into the bottom cover 705 under the action of gravity. When it is necessary to remove the bottom cover 705, simply remove the nut 707 and then pull the bottom cover 705 outward along the two guide rods 706. The operation is simple.

[0043] The present invention also provides a dough kneading machine, including a servo motor with a hollow shaft integrated cooling channel, wherein the servo motor body 1 not only has a good heat dissipation effect, but also avoids dust accumulation on its surface.

[0044] When using this invention, before installing the servo motor body 1 on the dough kneading machine, the dust cover 501 needs to be installed on the servo motor body 1. Simply pass the two wires 203 through the two rubber rings 504 on the dust cover 501. The rubber rings 504 provide a good sealing effect. Then connect the terminal block to the wires 203. Next, align the two clips 502 on the dust cover 501 with the two retainers 503 on the servo motor body 1, and press the dust cover 501 down so that the two clips 502 are respectively engaged in the two retainers 503. At this time, the installation of the dust cover 501 is completed. The dust cover 501 effectively prevents flour dust from directly adhering to the heat dissipation fins of the servo motor body 1, improves the heat dissipation effect of the servo motor body 1, and is easy to clean and highly flexible.

[0045] In order to improve the heat dissipation of the servo motor body 1 during operation, the DC motor 602 installed on the mounting frame 601 starts to run. The output shaft of the DC motor 602 drives the fan blade 603 to rotate. When the fan blade 603 rotates, it blows the air into the direction of the servo motor body 1, which achieves a good heat dissipation effect. At the same time, since the inner side of the dust cover 501 is provided with multiple guide strips 605, the air blown in flows along the gap between two guide strips 605 and is blown out from the air hole 606 at the other end of the dust cover 501, which effectively guides the flow of air and enhances the heat dissipation effect. Meanwhile, the fan mesh 604 at the outer end of the dust cover 501 provides a protective effect.

[0046] During the process of the DC motor 602 driving the fan blade 603 to rotate, the filter screen 703 engaged on the slide plate 702 effectively filters the flour dust mixed in the air, preventing the flour dust from being blown by the fan blade 603 towards the servo motor body 1. When it is necessary to clean the filter screen 703, simply pull the slide plate 702 outward. The slide plate 702 drives the filter screen 703 to slide outward. Since the rubber strip 704 installed on the slide block 701 has a "U" shaped structure, the rubber strip 704 effectively scrapes off the flour particles attached to both sides of the filter screen 703 during the sliding process. The scraped flour particles fall into the bottom cover 705 under the action of gravity. When it is necessary to remove the bottom cover 705, simply remove the nut 707 and then pull the bottom cover 705 outward along the two guide rods 706. The operation is simple.

[0047] When installing the servo motor body 1, if it is necessary to directly fix the servo motor body 1 to the dough kneading machine, in order to solve the problem of the deviation between the reserved hole on the servo motor body 1 and the hole on the dough kneading machine, simply fix the cover plate 303 to the front cover 204 on the servo motor body 1 with screws 306. Then, pass the four bolts 305 through the four mounting holes 301 respectively. Then, move the end of the bolt 305 into the adjustment groove 302. At this time, the end of the bolt 305 is engaged between the front cover 204 and the cover plate 303, preventing the bolt 305 from falling off. Then, the bolt 305 can be slid freely along the slide groove 304. Repeat the same operation and move the other three bolts 305 until the four bolts 305 are moved to correspond with the holes on the dough kneading machine. Then the servo motor body 1 can be installed. It is highly flexible and avoids the problem of having to re-drill holes when the holes do not correspond.

[0048] When the servo motor body 1 needs to be installed with the help of a bracket, simply tighten the rotating base 405 and the front end cover 204 of the servo motor body 1 with bolts 305, and then fix the mounting base 401 on the dough kneading machine. The operation is simple. When the servo motor body 1 is damaged and needs to be repaired, in order to avoid the problem of needing to remove the servo motor body 1 for repair and affecting the repair efficiency, simply rotate the servo motor body 1 by 90 degrees, which facilitates the disassembly and repair of the servo motor body 1. At this time, simply turn the knob 407 with a hex wrench. The knob 407 drives the limit block 406 to move upward until the limit block 406 no longer blocks the slider 403. Then pull the servo motor body 1 outward. At this time, the rotating base 405 drives the two sliders 403 to slide along the slide rod 402 and stretch the tension spring 404 until the end face of the mounting base 401 no longer blocks the rotation of the rotating base 405. At this time, the servo motor body 1 can be rotated by 90 degrees for repair. The operation is simple and the repair efficiency is improved.

[0049] The compiler 202 is installed at the end of the servo motor body 1 through the rear cover 201. The compiler 202 is configured to achieve precise control over the operating state of the servo motor body 1.
