DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0026] Example: Reference Figures 1-10 A food additive crushing device includes a base 101, on which a crushing cylinder 104 is movably provided, and a supporting rotating plate 103 is symmetrically fixedly installed on the outer side of the crushing cylinder 104, and the supporting rotating plates 103 are rotatably mounted on the base 101, and the axes of the two supporting rotating plates 103 are in the same straight line, and the axes of the supporting rotating plates 103 are parallel to the lower surface of the base 101, and a transposition motor 102 is fixedly mounted on the base 101, and the output shaft of the transposition motor 102 is fixedly connected to the corresponding supporting rotating plate 103. When the transposition motor 102 is started, the corresponding supporting rotating plate 103 is driven to rotate, so that the crushing cylinder 104 rotates relative to the base 101.

[0027] U-shaped groove plates 106 are symmetrically fixed on the circumferential surface of the crushing cylinder 104, fan-shaped cover plates 105 are slidably installed on the U-shaped groove plates 106, L-shaped slide plates 107 are fixedly provided on the outer sides of the fan-shaped cover plates 105, and expansion electric cylinders 108 are fixedly installed on the outer sides of the U-shaped groove plates 106, and the piston rod end of the expansion electric cylinder 108 is fixedly connected to the L-shaped slide plate 107.

[0028] In the initial position, the two fan-shaped cover plates 105 are located at the position closest to each other, that is, the two L-shaped slides 107 are located at the position closest to each other. At this time, a complete cylinder is formed between the crushing cylinder 104 and the two fan-shaped cover plates 105. The two expansion cylinders 108 are started to move the two L-shaped slides 107 away from each other, and then the two fan-shaped cover plates 105 are moved away from each other, so that the inner area of ​​the crushing cylinder 104 is opened, so that it is convenient to add the materials to be crushed into the crushing cylinder 104. The crushed raw materials are slidably matched with the two sides of the fan-shaped cover plate 105 and the U-shaped groove plate 106. Under the action of the U-shaped groove plate 106, when the fan-shaped cover plate 105 is opened, the attachments on the inner wall of the fan-shaped cover plate 105 fall onto the U-shaped groove plate 106. When the fan-shaped cover plate 105 is closed again, under the action of the fan-shaped cover plate 105, the attachments that fall on the U-shaped groove plate 106 are pushed back into the crushing cylinder 104, thereby preventing the raw materials attached to the fan-shaped cover plate 105 from falling directly out when the fan-shaped cover plate 105 is opened.

[0029] When it is necessary to add the raw materials to be crushed into the grinding cylinder 104, the transposition motor 102 is started to drive the grinding cylinder 104 to rotate, so that the fan-shaped cover 105 is located at the farthest position on the lower surface of the base 101, that is, the opening position of the grinding cylinder 104 is vertically upward at this time, and the axis of the grinding cylinder 104 is perpendicular to the lower surface of the base 101, so as to facilitate the addition of raw materials into the grinding cylinder 104.

[0030] When it is necessary to discharge the crushed raw materials in the crushing cylinder 104, start the shifting motor 102 to drive the crushing cylinder 104 to rotate, so that the fan-shaped cover 105 is located at the position closest to the lower surface of the base 101, that is, the opening position of the crushing cylinder 104 is vertically downward. At this time, the axis of the crushing cylinder 104 is perpendicular to the lower surface of the base 101, so that it is convenient to discharge the crushed raw materials in the crushing cylinder 104.

[0031] A ring-shaped rotating frame 109 is symmetrically mounted on the grinding cylinder 104, and a driving gear ring 112 is fixedly mounted on the ring-shaped rotating frame 109. The axis of the driving gear ring 112 and the grinding cylinder 104 are on the same straight line. A driving motor 114 is fixedly mounted on the ring-shaped rotating frame 109, and a driving gear 113 is fixedly mounted on the output shaft of the driving motor 114. The driving gear 113 and the corresponding driving gear ring 112 are engaged to form a gear pair. The driving motor 114 is started to drive the driving gear 113 to rotate. Under the action of the driving gear ring 112, the ring-shaped rotating frame 109 rotates relative to the grinding cylinder 104.

[0032] The annular rotating frame 109 is provided with an internal crushing assembly, which includes two adjusting circular plates 110 symmetrically mounted on the annular rotating frame 109. Under the action of the crushing cylinder 104, the fan-shaped cover plate 105, the annular rotating frame 109 and the adjusting circular plates 110, a cylindrical sealed crushing chamber is formed between the crushing cylinder 104, the two fan-shaped cover plates 105, the two annular rotating frames 109 and the four adjusting circular plates 110.

[0033] A crushing square rod 121 is fixedly installed on the adjusting circular plate 110, and the crushing square rod 121 is located on the inner side of the crushing cylinder 104. The crushing square rod 121 is used to crush the raw materials. The length of the crushing square rod 121 is equal to the distance between the two end faces of the crushing cylinder 104. Limiting short plates 116 are symmetrically fixed on both sides of the annular rotary frame 109. A limiting short column 125 is fixed on the adjusting circular plate 110. The limiting short column 125 is located between the two limiting short plates 116 on the corresponding adjusting circular plate 110. The limiting short plate 116 is used to limit the rotation angle of the adjusting circular plate 110. A torsion spring is provided between the adjusting circular plate 110 and the corresponding annular rotary frame 109. One end of the torsion spring is fixedly connected to the adjusting circular plate 110, and the other end of the torsion spring is fixedly connected to the annular rotary frame 109.

[0034] In the initial position, the torsion springs between the annular rotating frame 109 and the adjusting circular plate 110 are not compressed, and the crushing square rod 121 is located at the position closest to the inner surface of the crushing cylinder 104, but the crushing square rod 121 does not contact the inner surface of the crushing cylinder 104. At this time, the upper limit short column 125 on the annular rotating frame 109 contacts one of the corresponding two limit short plates 116.

[0035] Before driving the crushing square rod 121 to rotate relative to the crushing cylinder 104 to crush the raw materials in the crushing cylinder 104, first start the drive motor 114 to adjust the position of the annular rotary frame 109, so that the axes of the four adjustment circular plates 110 are arranged in a circular array relative to the axis of the crushing cylinder 104, that is, at this time, the four crushing square rods 121 are arranged in a circular array relative to the axis of the crushing cylinder 104, and then start the two drive motors 114 synchronously to drive the annular rotary frame 109 to rotate, and the adjustment circular plates 110 on the annular rotary frame 109 rotate synchronously, thereby causing the four crushing square rods 121 to rotate synchronously, so that the crushing square rods 121 crush the raw materials in the crushing cylinder 104.

[0036] It is worth noting that when the crushing square rod 121 crushes the raw materials of the crushing cylinder 104, it is necessary to ensure that the two annular rotating racks 109 rotate synchronously to prevent the crushing square rods 121 corresponding to the two annular rotating racks 109 from colliding.

[0037] A linkage unit is provided between the two adjustment circular plates 110 on the same annular rotating frame 109, and the linkage unit includes an adjustment outer gear ring 115. Fan-shaped support strips 111 are symmetrically fixedly installed on the annular rotating frame 109. The adjustment outer gear ring 115 is rotatably connected to the corresponding two fan-shaped support strips 111. An adjustment motor 117 is fixedly installed on the annular rotating frame 109, and an adjustment gear 118 is fixedly installed on the output shaft of the adjustment motor 117. The adjustment gear 118 and the adjustment outer gear ring 115 are meshed to form a gear pair. The axis of the adjustment outer gear ring 115 and the crushing cylinder 104 are on the same straight line. A linkage gear 128 is fixedly installed on the adjustment circular plate 110. Eight fan-shaped racks 127 are fixedly provided in a circular array on the adjustment outer gear ring 115. When the fan-shaped racks 127 and the linkage gear 128 are engaged, a gear rack pair is formed. There is a distance between two adjacent fan-shaped racks 127.

[0038] At the initial position, the sector racks 127 are not in contact with the linkage gear 128, that is, at this time, the torsion spring between the adjustment circular plate 110 and the annular rotating frame 109 is not compressed. When the crushing square rod 121 crushes the raw materials inside the crushing cylinder 104, the adjustment motor 117 is started to drive the adjustment gear 118 to rotate, that is, the adjustment outer gear ring 115 is rotated, and the sector racks 127 on the adjustment outer gear ring 115 are rotated synchronously. When the sector racks 127 contact the linkage gear 128, the linkage gear 128 rotates, the corresponding adjustment circular plate 110 rotates, the torsion spring between the adjustment circular plate 110 and the annular rotating frame 109 is compressed, and the crushing square rod 121 on the adjustment circular plate 110 is rotated. 21 rotates synchronously, that is, the position of the crushing square rod 121 inside the crushing cylinder 104 is changed, so that the crushing effect of the crushing square rod 121 on the raw material is improved by the position of the crushing square rod 121 inside the crushing cylinder 104. When the sector rack 127 makes the limiting short column 125 on the adjusting circular plate 110 contact another limiting short plate 116, the sector rack 127 disengages and engages with the linkage gear 128 on the adjusting circular plate 110. Since there is a distance between the two adjacent sector racks 127, that is, the linkage gear 128 is not engaged with any sector rack 127 at this time, under the action of the annular rotating frame 109 and the adjusting circular plate 110, the adjusting circular plate 110 returns to its initial position.

[0039] It is worth noting that the rotation speed of the adjustment outer gear ring 115 is much lower than the rotation speed of the annular rotating frame 109, that is, the position of the crushing square rod 121 inside the crushing cylinder 104 is changed in a smaller progress, thereby preventing the position of the crushing square rod 121 from being changed quickly, which would cause the crushing square rod 121 to be damaged due to excessive force, and the crushing square rod 121 is automatically reset by the torsion spring between the adjustment circular plate 110 and the annular rotating frame 109, avoiding the adjustment motor 117 from continuously controlling the forward and reverse rotation of the adjustment outer gear ring 115, which would reduce the service life of the adjustment motor 117.

[0040] The annular rotating frame 109 is provided with an external crushing assembly, which includes a second crushing square rod 122 symmetrically fixedly mounted on the annular rotating frame 109. The second crushing square rod 122 is used to achieve auxiliary crushing of the raw materials and clean the attachments on the inner wall of the crushing cylinder 104. The second crushing square rod 122 and the first crushing square rod 121 are equal in length. The surface of the second crushing square rod 122 farthest from the axis of the crushing cylinder 104 and the circumferential surface inside the crushing cylinder 104 are on the same circumferential surface.

[0041] When the annular rotating frame 109 is driven to rotate relative to the grinding cylinder 104, the four grinding square rods 122 also rotate synchronously. The grinding square rods 122 assist in grinding the raw materials in the grinding cylinder 104 inside the grinding cylinder 104, and because the grinding square rods 122 are in contact with the inner surface of the grinding cylinder 104, the attachments on the inner wall of the grinding cylinder 104 are scraped off.

[0042] Since the length of the crushing square rod 121 is equal to the distance between the two end faces of the crushing cylinder 104, in the process of the crushing square rod 121 crushing the raw materials in the crushing cylinder 104, the end of the crushing square rod 121 cleans the attachments on the end face of the crushing cylinder 104, that is, under the action of the crushing square rod 121 and the crushing square rod 2 122, the attachments on the inner wall of the sealed crushing chamber formed between the crushing cylinder 104, the two fan-shaped cover plates 105, the two annular rotating racks 109, and the four adjusting circular plates 110 are scraped off, and the scraped attachments continue to be crushed in the crushing cylinder 104, thereby improving the crushing effect of the raw materials in the crushing cylinder 104 and avoiding the raw materials adhering to the inner wall of the crushing cylinder 104 without being crushed.

[0043] The annular rotating frame 109 is provided with an inner scraping assembly, and the inner scraping assembly includes a cross slide 129, which is slidably mounted on the annular rotating frame 109. The cross slide 129 is provided with two auxiliary square rods 119 and two auxiliary square rods 123. The annular rotating frame 109 is symmetrically fixed with fan-shaped linkage strips 131. The fan-shaped linkage strips 131 and the auxiliary square rods 123 are spaced apart. The two fan-shaped linkage strips 131 and the two auxiliary square rods 123 on the same cross slide 129 are relative to the powder. The axes of the crushing cylinder 104 are arranged in a circular array, and the ends of the auxiliary square rods 119 closest to the corresponding cross slides 129 are fixedly installed with fan-shaped auxiliary strips 136. The fan-shaped auxiliary strips 136 are rotatably connected to the corresponding fan-shaped linkage strips 131. The auxiliary square rods 119 are slidably matched with the corresponding adjustment circular plates 110. The two auxiliary square rods 2 123 corresponding to the same cross slide 129 are symmetrically fixed on the cross slide 129, and the auxiliary square rods 2 123 are slidably matched with the corresponding annular rotating frame 109.

[0044] The cross slide 129 is driven to slide relative to the annular rotating frame 109, and the auxiliary square rod 2 123 and the fan-shaped linkage strip 131 on the cross slide 129 slide synchronously. The auxiliary square rod 2 123 slides relative to the annular rotating frame 109. Since the fan-shaped auxiliary strip 136 and the fan-shaped linkage strip 131 are rotationally connected, the auxiliary square rod 119 also moves synchronously, and the auxiliary square rod 119 slides relative to the corresponding adjustment circular plate 110.

[0045] The fan-shaped linkage strip 131 and the corresponding adjustment circular plate 110 have the same circumferential direction, and the fan-shaped auxiliary strip 136 and the corresponding fan-shaped linkage strip 131 have the same circumferential direction. When the adjustment circular plate 110 rotates relative to the annular rotating frame 109, under the action of the auxiliary square rod 119, the fan-shaped auxiliary strip 136 rotates relative to the corresponding fan-shaped linkage strip 131.

[0046] A scraping strip 120 is fixedly provided at the end of the auxiliary square rod 119. The scraping strip 120 is used to scrape off the attachments on the surface of the crushing square rod 121. The scraping strip 120 is fixedly installed on the corresponding auxiliary square rod 119 at the end farthest from the corresponding cross slide 129. The scraping strip 120 and the corresponding crushing square rod 121 are slidably matched, and there is a distance between the auxiliary square rod 119 and the corresponding crushing square rod 121.

[0047] When the crushing cylinder 104 is in the initial position, the end face of the scraping strip 120 farthest from the corresponding cross slide 129 and the end face of the crushing square rod 121 farthest from the corresponding cross slide 129 are on the same plane. At this time, the annular rotary frame 109 is driven to rotate relative to the crushing cylinder 104, and the auxiliary square rod 119 rotates synchronously to crush the raw materials inside the crushing cylinder 104. In the process of the crushing square rod 121 crushing the raw materials in the crushing cylinder 104, the cross slide 129 is driven to move away from the crushing cylinder 104, the auxiliary square rod 119 and the scraping strip 120 move synchronously, and the scraping strip 120 moves toward the annular rotary frame 109. Due to the sliding cooperation between the crushing square rod 121 and the scraping strip 120, the scraping strip 120 scrapes off the attachments on the surface of the crushing square rod 121, and the crushing square rod 121 lifts the raw materials in the crushing cylinder 104 upward, thereby improving the crushing effect of the raw materials.

[0048] A scraping slider 124 is fixedly provided at the end of the auxiliary square rod 123. The scraping slider 124 is used to scrape off the attachments on the surface of the auxiliary square rod 123. The scraping slider 124 is fixedly installed on the corresponding auxiliary square rod 123 at the end farthest from the corresponding cross slide 129. The scraping slider 124 and the corresponding crushing square rod 122 are slidably matched. There is no distance between the crushing square rod 122 and the auxiliary square rod 123. The crushing square rod 122 and the auxiliary square rod 123 are slidably matched.

[0049] In the initial position, the end face of the scraping slider 124 farthest from the corresponding cross slide 129 and the end face of the crushing square rod 2 122 farthest from the corresponding cross slide 129 are on the same plane. At this time, the annular rotary frame 109 is driven to rotate relative to the crushing cylinder 104, and the auxiliary square rod 2 123 rotates synchronously to crush the raw materials inside the crushing cylinder 104. In the process of the crushing square rod 2 122 crushing the raw materials in the crushing cylinder 104, the cross slide 129 is driven to move away from the crushing cylinder 104, and the auxiliary square rod 2 123 and the scraping slider 124 move synchronously, and the scraping slider 124 moves toward the direction close to the annular rotary frame 109. Due to the sliding cooperation between the scraping slider 124 and the crushing square rod 2 122, the attachments on the surface of the crushing square rod 2 122 are scraped off under the action of the scraping slider 124, and the scraping slider 124 lifts the raw materials in the crushing cylinder 104 upward, thereby improving the crushing effect of the raw materials.

[0050] The inner scraping rod 130 and the transmission gear 133 are rotatably mounted on the annular rotating frame 109. A torsion spring is provided between the inner scraping rod 130 and the annular rotating frame 109. One end of the torsion spring is fixedly connected to the annular rotating frame 109, and the other end of the torsion spring is fixedly connected to the inner scraping rod 130. The inner scraping rod 130 and the corresponding cross slide 129 form a spiral pair. A transmission group is provided between the inner scraping rod 130 and the corresponding transmission gear 133. The transmission group includes a transmission pulley 132, a linkage belt Wheel 134, fan-shaped auxiliary strip 136, the transmission pulley 132 is fixedly mounted on the inner scraper rod 130, the linkage pulley 134 is fixedly mounted on the transmission gear 133, the transmission belt 135 is arranged between the transmission pulley 132 and the linkage pulley 134, and the transmission ring plate 126 is fixedly mounted on the adjustment outer gear ring 115. Teeth are evenly arranged on four-fifths of the circumference of the transmission ring plate 126. The teeth on the transmission ring plate 126 and the transmission gear 133 form a gear pair when engaged.

[0051] In the initial position, the torsion spring between the inner scraping screw rod 130 and the annular rotating frame 109 is not compressed. At this time, the cross slide 129 is located at the position closest to the transmission pulley 132, that is, the scraping strip 120 and the scraping slider 124 are located at the position farthest from the corresponding annular rotating frame 109. The positioning motor 117 is started to drive the positioning outer gear ring 115 to rotate, and the transmission ring plate 126 rotates synchronously. When the teeth on the transmission ring plate 126 contact the transmission gear 133, under the action of the transmission pulley 132, the linkage pulley 134, and the transmission belt 135, the inner The scraper rod 130 rotates, causing the cross slide 129 to move away from the drive pulley 132, thereby causing the scraping strip 120 and the scraping slider 124 to move. When the transmission ring plate 126 causes the cross slide 129 to move to the position farthest from the drive pulley 132, the teeth on the transmission ring plate 126 disengage and engage with the transmission gear 133. Under the action of the torsion spring between the inner scraper rod 130 and the annular rotating frame 109, the cross slide 129 returns to its initial position, and the above steps are repeated to realize the reciprocating movement of the cross slide 129.

[0052] Working principle: Start the transposition motor 102 so that the fan-shaped cover plate 105 is located at the farthest position from the lower surface of the base 101, start the expansion electric cylinder 108 to move the two fan-shaped cover plates 105 to the farthest position, and then add the raw materials to be crushed into the crushing cylinder 104. After the addition is completed, start the expansion electric cylinder 108 to move the two fan-shaped cover plates 105 to the closest position.

[0053] Then, the two driving motors 114 are started synchronously, so that the two annular rotating frames 109 rotate synchronously. Under the action of the inner crushing assembly and the outer crushing assembly, the auxiliary square rod 119, the crushing square rod 121, the crushing square rod 2 122, and the auxiliary square rod 2 123 realize the crushing of the raw materials in the crushing cylinder 104, and under the action of the crushing square rod 121 and the crushing square rod 2 122, the attachments inside the crushing chamber are scraped off, and the two positioning motors 117 are started. Under the action of the inner scraping assembly, the scraping strips 120 and the auxiliary square rod 2 123 respectively scrape off the attachments on the crushing square rods 1 121 and 12, so that the raw materials can be fully crushed, that is, the crushing effect of the raw materials is improved.

[0054] After the raw materials are crushed, the transposition motor 102 is started to rotate the fan-shaped cover 105 to the position closest to the lower surface of the base 101. A collection box can be set on the base 101, and then the two fan-shaped cover plates 105 are opened. The crushed raw materials in the crushing cylinder 104 fall into the collection box below, and the two annular rotating racks 109 are driven to rotate. Under the action of the crushing square rod 122, all the crushed raw materials in the crushing cylinder 104 can fall down.

[0055] The present invention is not limited to the above-mentioned specific embodiments. Various modifications made by technicians in the relevant technical field based on the above-mentioned conception without creative work are all within the scope of protection of the present invention.
