[0007] The main body of the present invention also includes a sealing block; the sealing block is connected to the circumferential surface of the preparation cylinder through a connecting component.

[0008] The movable groove described in this invention consists of four spiral inclined structures arranged symmetrically.

[0009] The sealing block of the present invention has a minor arc structure, the inner circumferential surface dimension of the sealing block is smaller than the outer circumferential surface dimension of the sealing block, and the center of the sealing block is located on the axis of the preparation cylinder.

[0010] The guiding component of the present invention includes a guide groove and a guide block; the circumferential surface of the transmission rod is provided with a plurality of guide grooves in a ring array; the guide block is slidably inserted into the guide groove and fixedly connected to the inner circumferential surface of the movable ring column.

[0012] The connecting block of the present invention has an arc-shaped right-angled triangular structure. The shape of the connecting block is adapted to the shape of the connecting groove, and the connecting groove and the sealing groove form a V-shaped structure.

[0013] The positioning component of this invention includes a sliding groove, a sliding block, a transmission groove, a transmission ball, a positioning groove, a sliding rod, a spring, a limiting groove, a limiting block, and a connecting plate. Two sliding grooves are symmetrically formed within the sealing block. The sliding block is slidably disposed within the sliding groove. A transmission groove is formed on the inner wall of the sliding groove.

[0019] The technical solution of the present invention will now be described with reference to the accompanying drawings.

[0020] like Figures 1-11 As shown, the taro paste preparation device of the present invention includes a body 1 for taro paste, a stirring and crushing component 2, and a guiding component 3; the body 1 includes a preparation cylinder 101 and a sealing block 102, the sealing block 102 having a minor arc structure; the preparation cylinder 101 is provided with a feeding port, and the preparation cylinder 101 is provided with the stirring and crushing component 2; the sealing block 102 is connected to the circumferential surface of the preparation cylinder 101 through a connecting component 4; the sealing block 102 has a minor arc structure, the inner circumferential surface dimension of the sealing block 102 is smaller than the outer circumferential surface dimension of the sealing block 102, and the center of the sealing block 102 is located on the axis of the preparation cylinder 101, so as to cooperate with the connecting groove 402 to form a V-shaped structure.

[0021] The mixing and crushing assembly 2 includes a fixed cylinder 201, a servo motor 202, a transmission rod 203, a mixing rod 204 for mixing taro paste, a movable ring column 205, a crushing rod 206 for crushing taro paste, a moving groove 207, and a moving pin 208. The fixed cylinder 201 is fixedly connected to the top surface of the preparation cylinder 101. The servo motor 202 is fixedly connected to the outer circumferential surface of the fixed cylinder 201 via a motor base. One end of the transmission rod 203 is fixedly connected to the output end of the servo motor 202, and the other end extends through the fixed cylinder 201 into the preparation cylinder 101. Three mixing rods 204 are fixedly connected in a ring array on the circumferential surface of the transmission rod 203 and are positioned within the preparation cylinder 101. Inside 01; the movable ring column 205 is movably sleeved on the transmission rod 203 through the guide assembly 3 and is located inside the fixed cylinder 201, and the end of the movable ring column 205 extends through the fixed cylinder 201 into the preparation cylinder 101; three crushing rods 206 are fixedly connected in a ring array on the circumferential surface of the movable ring column 205 and are located inside the preparation cylinder 101; a moving groove 207 is opened on the circumferential surface of the movable ring column 205; two moving pins 208 are symmetrically slidably inserted into the moving groove 207, and the moving pins 208 are fixedly connected to the inner circumferential surface of the fixed cylinder 201; the moving groove 207 is formed by four spiral inclined structures symmetrically arranged to achieve the effect of up and down reciprocating movement.

[0022] The guide assembly 3 includes a guide groove 301 and a guide block 302; the transmission rod 203 has three guide grooves 301 arranged in a ring on its circumferential surface; the guide block 302 slides through the guide groove 301 and is fixedly connected to the inner circumferential surface of the movable ring column 205.

[0023] This invention, by setting up a mixing and crushing component 2 and a guiding component 3, allows an appropriate amount of taro paste to be added into the preparation cylinder 101 through the feeding port. Then, a servo motor 202 is activated, causing the output shaft of the servo motor 202 to drive the transmission rod 203 to rotate, causing the mixing rod 204 to rotate within the preparation cylinder 101. This allows the mixing rod 204 to mix the taro paste. Furthermore, as the transmission rod 203 rotates, the side of the guide block 302 presses against the inner wall of the guide groove 301, causing the movable ring column 205 to rotate within the fixed cylinder 201. This causes the movable pin 208 to slide from the lower end to the upper end of the movable groove 207, allowing the movable ring column 205 to slide downwards within the fixed cylinder 201. This, in turn, causes the guide block 302 to slide within the guide groove 301, thus crushing the taro paste. The rod 206 rotates and moves downward within the preparation cylinder 101, allowing it to crush the taro paste raw material. This continues until the moving pin 208 slides to the high end of the moving groove 207. At this point, the moving pin 208 slides from the high end to the low end of the moving groove 207, causing the crushing rod 206 to rotate and move upward within the preparation cylinder 101 until it slides to the low end of the moving groove 207. This process is repeated, allowing the stirring rod 204 and the crushing rod 206 to continuously stir and crush the taro paste raw material. Compared to existing technologies, this invention has a reasonable structural design, enabling simultaneous stirring and crushing of the taro paste raw material. This not only reduces preparation time and improves efficiency but also results in a smoother, more delicate texture and more complete blending.

[0024] The connecting component 4 includes a sealing groove 401, a connecting groove 402, and a connecting block 403. The sealing groove 401 is provided on the preparation cylinder 101. The sealing block 102 is inserted into the sealing groove 401 through the positioning component 5, and the shape of the sealing block 102 is adapted to the shape of the sealing groove 401. Two connecting grooves 402 are symmetrically provided on both sides of the sealing groove 401. Two connecting blocks 403 are symmetrically fixedly connected to both sides of the sealing block 102, and the connecting blocks 403 are in contact with the inner wall of the connecting groove 402. The connecting block 403 is an arc-shaped right-angled triangular structure, and the shape of the connecting block 403 is adapted to the shape of the connecting groove 402. The connecting groove 402 and the sealing groove 401 form a V-shaped structure.

[0025] This invention, by setting up a connecting component 4, after the taro paste raw material is stirred and crushed, controls the servo motor 202 to stop rotating its output shaft. Then, the positioning component 5 causes the sealing block 102 to slide upward within the sealing groove 401, and the connecting block 403 to slide upward within the connecting groove 402, until the sealing block 102 is removed from the sealing groove 401. At this point, not only can the stirred and crushed taro paste raw material in the preparation cylinder 101 be removed through the sealing groove 401, but it also facilitates the cleaning and maintenance of the preparation cylinder. The inner wall of 101, the stirring rod 204 and the crushing rod 206 are cleaned. Since the connecting block 403 is an arc-shaped right-angled triangular structure, it can not only cooperate with the sealing groove 401 to restrict the position of the sealing block 102, but also extend the contact area between the connecting block 403 and the connecting groove 402, thereby improving the sealing effect of the sealing block 102. Since the connecting groove 402 and the sealing groove 401 form a V-shaped structure, it can prevent the taro paste from being stuck in the sealing groove 401 and affecting the insertion effect of the sealing block 102 and the sealing groove 401.

[0026] Positioning component 5 includes a sliding groove 501, a sliding block 502, a transmission groove 503, a transmission ball 504, a positioning groove 505, a sliding rod 506, a spring 507, a limiting groove 508, a limiting block 509, and a connecting plate 510; two sliding grooves 501 are symmetrically formed inside the sealing block 102; the sliding block 502 is slidably disposed within the sliding groove 501; a transmission groove 503 is formed on the inner sidewall of the sliding groove 501; the transmission ball 504 is slidably disposed through the transmission groove 503. Inside, the spherical surface of the transmission ball 504 contacts the inner wall of the transmission groove 503 and the side of the sliding block 502; two positioning grooves 505 are symmetrically opened on both sides of the inner wall of the sealing groove 401, and the transmission ball 504 is inserted into the positioning groove 505. The positioning groove 505 has a slightly curved spherical structure so that the transmission ball 504 can move out of the positioning groove 505; the sliding rod 506 slides through the sliding groove 501, and one end of the sliding rod 506 is fixedly connected to the sliding block 502; the spring 5 Spring 507 is fitted onto sliding rod 506, and both ends of spring 507 are fixedly connected to the inner top wall of sliding groove 501 and sliding block 502 respectively; a limiting groove 508 is provided on the inner side wall of sliding groove 501; limiting block 509 slides through limiting groove 508 and is fixedly connected to sliding block 502; connecting plate 510 is fixedly connected to the other end of the two sliding rods 506, and the shape of connecting plate 510 is adapted to the shape of sealing block 102; sliding block 502 is a right-angled trapezoidal structure. The sliding block 502 is inclined downwards, and the size of the side of the sliding block 502 near the transmission ball 504 is smaller than the size of the side of the sliding block 502 away from the transmission ball 504, so that the transmission ball 504 has a accommodating space; when the top wall of the limiting block 509 contacts the inner top wall of the limiting groove 508, the spring 507 is not compressed beyond the elastic range; when the spherical surface of the transmission ball 504 contacts the inclined surface of the sliding block 502, the spherical surface of the transmission ball 504 contacts the inner side wall of the transmission groove 503.

[0027] This invention utilizes a positioning component 5. By pulling the handle on the connecting plate 510, the connecting plate 510 moves upward, causing the sliding rod 506 to move upward. This causes the sliding block 502 to slide upward within the sliding groove 501, and the limiting block 509 to slide upward within the limiting groove 508. This causes the spring 507 to contract under pressure until the top wall of the limiting block 509 contacts the top wall of the limiting groove 508. At this point, the spring 507 stops contracting. Continuing to pull the handle on the connecting plate 510 will cause the sealing block 102 to move within the sealing groove. Slide the ball upwards within 401, causing the spherical surface of the transmission ball 504 to press against the inner wall of the positioning groove 505, allowing the transmission ball 504 to slide within the transmission groove 503 until the spherical surface of the transmission ball 504 no longer contacts the inner wall of the positioning groove 505. At this point, the spherical surface of the transmission ball 504 contacts the inclined surface of the sliding block 502 until the sealing block 102 is moved out of the sealing groove 401. After the operation is completed, reinstall the sealing block 102 so that the transmission ball 504 can be inserted into the positioning groove 505, thereby improving the insertion stability of the sealing block 102 and the sealing groove 401.

[0028] Furthermore, the present invention also provides a method for using a taro paste preparation device, which includes the following steps: Step 1: Add the taro paste raw material into the preparation cylinder 101 through the feeding port on the preparation cylinder 101.

[0029] Step 2: Start the servo motor 202, which causes the transmission rod 203 to drive the stirring rod 204 to rotate, so that the stirring rod 204 can stir the taro paste raw material. When the transmission rod 203 rotates, it will cause the crushing rod 206 to move up and down, so that the crushing rod 206 can crush the taro paste raw material.

[0030] Step 3: After the taro paste is mashed and crushed, pull the handle on the connecting plate 510 so that the spherical surface of the transmission ball 504 is no longer in contact with the side of the sliding block 502. Then, by pulling the handle on the connecting plate 510, the sealing block 102 can slide upward in the sealing groove 401, so that the transmission ball 504 can be moved out of the positioning groove 505.

[0031] Step 4: The connecting block 403 contacts the inner wall of the connecting groove 402, which not only helps to restrict the position of the sealing block 102 in conjunction with the sealing groove 401, but also extends the contact area between the connecting block 403 and the connecting groove 402, thereby improving the sealing effect of the sealing block 102.

[0032] Step 5: After the sealing block 102 is removed from the sealing groove 401, the taro paste raw material that has been stirred and crushed in the preparation cylinder 101 can be taken out through the sealing groove 401 and then the sealing block 102 can be reinstalled.

[0033] Servo motor 202 is a standard instrument, model R88M-K. A brake is installed on the output shaft of servo motor 202. When powered on, it opens to allow the output shaft of servo motor 202 to rotate. When powered off, it automatically locks the output shaft of servo motor 202, thereby achieving mechanical self-locking. It can also be adjusted in real time through a closed-loop feedback mechanism to achieve high-precision control of position, speed and torque.

[0034] In use, first, add an appropriate amount of taro paste raw material into the preparation cylinder 101 through the feeding port on the preparation cylinder 101. Then, start the servo motor 202, causing the output shaft of the servo motor 202 to drive the transmission rod 203 to rotate, causing the stirring rod 204 to rotate inside the preparation cylinder 101. This allows the stirring rod 204 to stir the taro paste raw material. When the transmission rod 203 rotates, it causes the side of the guide block 302 to press against the inner wall of the guide groove 301, causing the movable ring column 205 to rotate inside the fixed cylinder 201. This causes the moving pin 208 to slide from the lower end of the moving groove 207 to the upper end of the moving groove 207, allowing the movable ring column 205 to rotate within the fixed cylinder. The guide block 302 slides downward within the guide groove 301, causing the crushing rod 206 to rotate and move downward within the preparation cylinder 101. This allows the crushing rod 206 to crush the taro paste raw material until the moving pin 208 slides to the high end of the moving groove 207. At this point, the moving pin 208 will slide from the high end to the low end of the moving groove 207, causing the crushing rod 206 to rotate and move upward within the preparation cylinder 101 until the moving pin 208 slides to the low end of the moving groove 207. This process is repeated, allowing the stirring rod 204 and the crushing rod 206 to continuously stir and crush the taro paste raw material.

[0035] After the taro paste ingredients are mashed and crushed, the servo motor 202 is controlled to stop rotating. Then, by pulling the handle on the connecting plate 510, the connecting plate 510 is moved upward, causing the sliding rod 506 to move upward, and the sliding block 502 to slide upward in the sliding groove 501. The limiting block 509 slides upward in the limiting groove 508, causing the spring 507 to contract under force until the top wall of the limiting block 509 contacts the top wall of the limiting groove 508. At this point, the spring 507 stops contracting. Continuing to pull the handle on the connecting plate 510 will cause the sealing block 102 to slide upward in the sealing groove 401, and the connecting block 403 to slide upward in the connecting groove 402. This causes the spherical surface of the transmission ball 504 to press against the inner wall of the positioning groove 505, causing the transmission ball 504 to slide in the transmission groove 503 until the spherical surface of the transmission ball 504 no longer contacts the inner wall of the positioning groove 505. Upon re-contact, the spherical surface of the transmission ball 504 contacts the inclined surface of the sliding block 502 until the sealing block 102 is removed from the sealing groove 401. At this point, not only can the taro paste raw material that has been stirred and crushed in the preparation cylinder 101 be taken out through the sealing groove 401, but it is also convenient to clean the inner wall of the preparation cylinder 101, the stirring rod 204, and the crushing rod 206. Since the connecting block 403 is an arc-shaped right-angled triangular structure, it can not only restrict the position of the sealing block 102 in conjunction with the sealing groove 401, but also extend the contact area between the connecting block 403 and the connecting groove 402, thereby improving the sealing effect of the sealing block 102. Since the connecting groove 402 and the sealing groove 401 form a V-shaped structure, the taro paste can be prevented from being stuck in the positioning groove 505. After the operation is completed, the sealing block 102 is reinstalled, so that the inclined surface of the sliding block 502 presses against the spherical surface of the transmission ball 504, and the transmission ball 504 is inserted into the positioning groove 505.

[0036] The structure of the present invention is described in accordance with the accompanying drawings, but the scope of protection of the present invention is not limited thereto. Equivalent substitutions or changes made to the technical solution of the present invention shall be within the scope of protection of the present invention.
