Description

Technical Field

[0001] The present invention relates to the technical field of dried tofu cutting machines, and particularly to a dried tofu cutting machine with adjustable knife distance. Background Technique

[0002] A dried tofu cutting machine is a food machine dedicated to processing dried tofu into specific shapes and sizes. It belongs to the core cutting device in the production equipment of soy products. In order to cut dried tofu of different sizes, the cutting structure in the dried tofu cutting machine generally has a tool adjustment function.

[0003] Currently, when the existing dried tofu cutting machine is in use, the worn cutting tools need to be replaced regularly. When replacing the cutting tools, since the cutting tools face downwards and the cutting tools usually include a large horizontal blade and multiple small vertical blades, and these small blades are in close contact with the large blade, a large amount of time is required to adjust the observation angle when checking the large and small blades before replacing the tools, so as to fully observe the wear degree of the multiple small blades and the large blade. Then, tools are used to remove the blades to be replaced and install new blades. Therefore, the replacement of the cutting tools will waste a lot of time, and there is a problem of slow replacement efficiency.

[0004] Combining the above problems, we will find that when the existing dried tofu cutting machines with adjustable knife distance on the market are in use, it is very difficult to avoid the above-mentioned problems at the same time. And even if it can be solved, it needs to be solved with the cooperation of external tools, so it cannot achieve the effect we expect.

[0040] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0041] Embodiment 1: Please refer to Figure 1 , Figures 3 - 7 , the present invention provides a technical solution: A dried bean curd cutting machine with adjustable knife distance includes two support plates 1. A replacement mechanism 2 is jointly arranged above the two support plates 1, and a collection mechanism 3 is jointly arranged above the two support plates 1;

[0042] The replacement mechanism 2 includes a flipping unit 21. The flipping unit 21 is arranged above the two support plates 1, and the flipping unit 21 can flip the cutting structure to a state where the blade faces upward.

[0043] As a further limitation of the replacement mechanism 2 of the present invention, the flipping unit 21 includes a fixing plate 2101. Two first hydraulic rods 2102 are fixedly connected to the inner wall of the fixing plate 2101. The telescopic ends of the two first hydraulic rods 2102 are commonly fixedly connected to a lifting plate 2108. A first rectangular plate 2105 is fixedly connected to the outer surface of the fixing plate 2101. A second rectangular plate 2104 is fixedly connected to the outer surface of the lifting plate 2108. A first threaded shaft 2106 is threadedly connected to the inner walls of both the first rectangular plate 2105 and the second rectangular plate 2104. A toothed plate 2107 is rotatably connected to the outer surface of each first threaded shaft 2106. The outer surface of each toothed plate 2107 is in contact with the outer surfaces of both the fixing plate 2101 and the lifting plate 2108. Two rotating shafts 2110 are rotatably connected to the inner wall of the lifting plate 2108. A turntable 2103 is fixedly connected to one end of each of the two rotating shafts 2110 close to each other. A transmission gear 2109 is fixedly connected to one end of each of the two rotating shafts 2110 away from each other. The outer surface of each transmission gear 2109 is meshed with the outer surface of the toothed plate 2107. By providing the flipping unit 21, the flipping unit 21 can flip the first blade 2211 and the second blade 2213 to a state where the blade faces upward, eliminating the need for workers to bend down and lower their heads for a long time and frequently change angles to check the tool wear state. This can not only increase the safety of workers but also improve the inspection efficiency of workers for the tool wear state.

[0044] The specific implementation manner of this embodiment is as follows: When it is necessary to replace the first blade 2211 and the second blade 2213, it is necessary to check the wear degree of the first blade 2211 and the second blade 2213. At this time, rotational power can be applied to the first threaded shaft 2106 located in the front. With the threaded connection relationship between the first threaded shaft 2106 and the toothed plate 2107, the toothed plate 2107 can be driven to move to the right, so that the toothed plate 2107 located in the front does not mesh with the transmission gear 2109 located in the front. At this time, control the first hydraulic rod 2102 to operate. When the first hydraulic rod 2102 operates, it will push the lifting plate 2108 to move downward. When the lifting plate 2108 moves downward, it will drive the two rotating shafts 2110, the transmission gear 2109 and the turntable 2103 rotatably connected to the inner wall to move downward synchronously. However, at this time, the toothed plate 2107 located in the rear still has a meshing relationship with the rear transmission gear 2109, and the toothed plate 2107 located in the rear is connected to the first threaded shaft 2106 and the first rectangular plate 2105. Therefore, the toothed plate 2107 located in the rear and the first threaded shaft 2106 will not move downward synchronously with the lifting plate 2108. By using the meshing relationship between the rear transmission gear 2109 and the toothed plate 2107, the transmission gear 2109 can rotate while moving downward following the lifting plate 2108, thereby driving the turntable 2103 located in the rear to rotate. The turntable 2103 located in the rear will transmit the power to the turntable 2103 located in the front through the second threaded shaft 2232 and the limiting shaft 2233, thereby driving a plurality of rectangular blocks 2203 and the fixing frame 2204 to rotate counterclockwise by 180 degrees. Thus, a plurality of identical second blades 2213 can be driven to rotate by 180 degrees, making the cutting edge of the second blade 2213 face upward to observe the wear condition of the second blade 2213. After observing the second blade 2213, the worker can check the wear degree of the first blade 2211. At this time, the first blade 2211 does not contact the second blade 2213, so there is no dead angle, greatly increasing the convenience when checking the wear degree of the first blade 2211. After observing the wear degrees of the first blade 2211 and the second blade 2213, control the first hydraulic rod 2102 to reset. During the reset process of the first hydraulic rod 2102, when the rear transmission gear 2109 moves upward synchronously, it will also mesh with the toothed plate 2107 located in the rear. Therefore, the rear transmission gear 2109 will rotate clockwise by 180 degrees to cause the second blade 2213 to reset;

[0045] After all the second blades 2213 are reset, rotational power is applied to the front first threaded shaft 2106 to cause the front toothed plate 2107 to engage with the front transmission gear 2109, and reverse rotational power is applied to the rear first threaded shaft 2106 to drive the rear toothed plate 2107 to stop engaging with the rear transmission gear 2109. At this time, when the first hydraulic rod 2102 pushes the lifting plate 2108 downward, since the front second rectangular plate 2104 is fixed to the lifting plate 2108, the second rectangular plate 2104 will also descend with the descent of the lifting plate 2108, and the front toothed plate 2107 will limit the front transmission gear 2109 to prevent the front transmission gear 2109 from rotating, further avoiding the rotation of the second blade 2213. It should be understood here that during normal operation and blade replacement of the equipment, the front toothed plate 2107 is always engaged with the front transmission gear 2109, and the rear toothed plate 2107 is not engaged with the rear transmission gear 2109. Only when observing the wear degree of the blade, the front toothed plate 2107 is not engaged with the front transmission gear 2109, and the rear toothed plate 2107 is engaged with the rear transmission gear 2109. If the first blade 2211 and the second blade 2213 are in good condition and do not need to be replaced, the second stepping motor 2229 is controlled to drive the third gear 2238 to rotate, thereby driving the toothed belt 2230 to rotate. Thus, the dried tofu can be placed on the toothed belt 2230 for conveying. Subsequently, the first hydraulic rod 2102 is controlled to push the first blade 2211 and the second blade 2213 downward to cut the dried tofu, effectively avoiding the problem that a large amount of time is required to observe the wear degree of the cutting tool before replacing the cutting tool of the equipment.

[0046] Embodiment 2: Please refer to Figures 1 - 5 and Figures 8 - 14 , the present invention provides a technical solution: a dried tofu cutting machine with adjustable knife distance. The present invention makes corresponding improvements to the technical problems mentioned in the background art. The replacement mechanism 2 further includes a replacement unit 22. The replacement unit 22 is arranged above the two support plates 1. The replacement unit 22 cooperates with the flipping unit 21, and the replacement unit 22 can replace the cutting tool.

[0047] As a further limitation of the replacement mechanism 2 of the present invention, the replacement unit 22 includes a first stepping motor 2205. The output end of the first stepping motor 2205 is fixedly connected to a transmission shaft 2206.

Three groups of second one-way bearings 2214 are rotatably connected to the inner wall of each fixing frame 2204. The inner ring of each second one-way bearing 2214 is fixedly connected to a second rubber roller 2215. Two groups of second spiral cylinders 2216 are rotatably connected to the inner wall of each fixing frame 2204. The outer surface of each second spiral cylinder 2216 is fixedly connected to a second limiting plate 2217. A second blade 2213 is arranged inside each fixing frame 2204. The front surface of one of the support plates 1 is fixedly connected to a bottom plate 2207 and a replacement frame 2218 respectively. A replacement groove 2241 is formed on the upper surface of the replacement frame 2218. Two first lifting shafts 2221 are slidably connected to the inside of the replacement frame 2218. The top end of each first lifting shaft 2221 is fixedly connected to a first spiral block 2225. The bottom end of each first lifting shaft 2221 is fixedly connected to a fixing block 2223. A number of identical tool holders 2227 are arranged inside the replacement frame 2218. Two groups of second lifting shafts 2222 are slidably connected to the inside of each tool holder 2227.

Two second hydraulic rods 2219 are fixedly connected to the inner wall of the bottom plate 2207. The telescopic ends of the two second hydraulic rods 2219 are jointly fixedly connected to a lifting box 2220. By setting the replacement unit 22, the replacement unit 22 can be used to replace the severely worn tools, thus effectively avoiding the problems that when the equipment is in use, when workers replace the severely worn tools, each tool replacement is accompanied by a certain degree of danger and the replacement efficiency is slow.

[0048] Please refer to Figures 6 - 8, at one end where the two turntables 2103 are close to each other, a second threaded shaft 2232 and a limiting shaft 2233 are fixedly connected together. A number of identical circular cylinders 2235 are threadedly connected to the outer surface of the second threaded shaft 2232. At both ends of each circular cylinder 2235, a first gear 2234 is fixedly connected. The outer surface of each circular cylinder 2235 is rotatably connected to the inner wall of a rectangular block 2203. The inner part of each fixing frame 2204 is slidably connected to the outer surface of the limiting shaft 2233. The outer surface of a first stepping motor 2205 is fixedly connected to the front surface of one of the support plates 1.

The outer surface of each first rubber roller 2209 is rotatably connected to the inner wall of a lifting plate 2108. The number of each group of first one-way bearings 2210 is two. The outer surfaces of the two groups of first rubber rollers 2209 are respectively in contact with the front surface and the back surface of a first blade 2211. By providing the second threaded shaft 2232 and the limiting shaft 2233, using the threaded connection relationship between the second threaded shaft 2232 and the circular cylinder 2235, the position of the circular cylinder 2235 can be adjusted. Further, the positions of the rectangular block 2203, the fixing frame 2204 and the second blade 2213 can be adjusted. And the circular cylinder 2235 rotates inside the inner wall of the rectangular block 2203, which can ensure that the power during the rotation of the circular cylinder 2235 will not act on the circular cylinder 2235. And the limiting shaft 2233 can limit the fixing frame 2204, further preventing the fixing frame 2204 and the rectangular block 2203 from rotating. And the existence of the first gear 2234 is to facilitate applying external power to the circular cylinder 2235.

[0049] Please refer to Figure 11 and Figure 13, the inner wall of the replacement rack 2218 is fixedly connected with a third threaded shaft 2208.

The left side surface of each second blade 2213 is in contact with the right side surface of the first blade 2211. By providing the third threaded shaft 2208 and the moving cylinder 2201, using the threaded connection relationship between the moving cylinder 2201 and the third threaded shaft 2208, the position of the moving cylinder 2201 can be adjusted, and further the position of the tool holder 2227 can be adjusted. Moreover, since the moving cylinder 2201 is rotatably connected to the inner wall of the tool holder 2227, the tool holder 2227 can be prevented from rotating following the moving cylinder 2201.

[0050] Please refer to Figure 2 , two third gears 2238 are rotatably connected to the inner walls of two supporting plates 1 together. A toothed belt 2230 is meshed with the outer surfaces of the two third gears 2238 together. The front surface of one of the supporting plates 1 is fixedly connected with a support base 2228. The upper surface of the support base 2228 is fixedly connected with a second stepping motor 2229. The output end of the second stepping motor 2229 is fixedly connected to one end of one of the third gears 2238 close to the second stepping motor 2229. By providing the second stepping motor 2229, the second stepping motor 2229 can be used to drive the third gear 2238 to rotate when it operates, thereby driving the toothed belt 2230 to rotate and achieving the purpose of conveying dried tofu.

[0051] Please refer to Figure 1 and Figure 2 , the upper surface of the other supporting plate 1 is fixedly connected with a support shaft 2231. The top end of the support shaft 2231 is in contact with the bottom surface of the fixing plate 2101. A support frame 2237 is arranged on the right side of one of the supporting plates 1. The number of each group of second lifting shafts 2222 is two. The outer surfaces of each second lifting shaft 2222 and the outer surface of the first lifting shaft 2221 are both slidably connected to the inside of the replacement rack 2218. By providing the support shaft 2231, the support shaft 2231 can be used to provide a supporting force for the fixing plate 2101 during the cutting work. When replacing the tool, the bottom surface of the supporting plate 1 will be in contact with the upper surface of the support frame 2237. Therefore, the support frame 2237 can also provide support for the supporting plate 1 during tool replacement.

[0052] Please refer toFigure 2 and Figure 16 One of the front sides of the support plates 1 is fixedly connected with a hook 2240. An N-shaped plate 2239 is arranged outside the hook 2240. The outer surface of the N-shaped plate 2239 is in contact with the outer surface of the hook 2240. Teeth are arranged on the outer surface of the N-shaped plate 2239. The inner bottom wall of the lifting box 2220 is in contact with the outer surfaces of a plurality of first bull's-eye bearings 2224. The inner bottom wall of the lifting box 2220 is fixedly connected to the bottom surfaces of two fixing blocks 2223. The outer surfaces of each second lifting shaft 2222 are all slidably connected inside the lifting box 2220. By providing the hook 2240, the hook 2240 can provide a supporting force for the N-shaped plate 2239, and the presence of the N-shaped plate 2239 can facilitate the action of force on the first gear 2234 and the second gear 2202.

[0053] The specific implementation manner of this embodiment is as follows: When it is necessary to adjust the distance between the second blades 2213, the N-shaped plate 2239 is removed. The teeth on the surface of the N-shaped plate 2239 can be meshed with the teeth on the surfaces of the first gear 2234 and the second gear 2202. After the teeth on the surface of the N-shaped plate 2239 are meshed with the teeth on the surface of the first gear 2234 from the right side, pulling the N-shaped plate 2239 upward can drive the two adjacent first gears 2234 to rotate. When the first gear 2234 rotates, it will drive the circular cylinder 2235 to rotate synchronously. By using the threaded connection relationship between the circular cylinder 2235 and the second threaded shaft 2232, the position of the circular cylinder 2235 can be adjusted. It should be understood here that the circular cylinder 2235 is rotatably connected to the inner wall of the rectangular block 2203, and the fixing frame 2204 fixed to the bottom surface of the rectangular block 2203 slides on the surface of the limiting shaft 2233. Therefore, the limiting shaft 2233 can limit the fixing frame 2204 and the rectangular block 2203 to prevent the rectangular block 2203 from rotating, so that the rectangular block 2203 only undergoes horizontal displacement. Thus, the distance between the second blades 2213 can be adjusted. Similarly, repeating the above steps can adjust the distance of the tool holder 2227. It should be understood here that when the tool holder 2227 is adjusted in distance, it will synchronously drive the two groups of second lifting shafts 2222 sliding inside the tool holder 2227 to move. Therefore, it can be understood that the second lifting shaft 2222 can not only slide up and down inside the replacement frame 2218, but also slide left and right inside the lifting shaft, while the first lifting shaft 2221 can only slide up and down inside the replacement frame 2218;

[0054] When it is necessary to replace the worn blades, place the first blade 2211 and the second blade 2213 to be replaced in the replacement slots 2241 and the tool holder 2227 respectively. Then, control the first stepping motor 2205 to operate, so that the first stepping motor 2205 drives the transmission shaft 2206 and the fixing plate 2101 fixed at the top of the transmission shaft 2206 to rotate clockwise by 90 degrees. At this time, the fixing plate 2101 will rotate to directly above the replacement frame 2218. Then, control the second hydraulic rod 2219 to extend upward, pushing the lifting box 2220 fixed at the telescopic end of the second hydraulic rod 2219 to move upward. Further, it can push the first lifting shaft 2221 and the second lifting shaft 2222 to move upward, so that the first spiral block 2225 fixed at the top of the first lifting shaft 2221 and the second spiral block 2226 fixed at the top of the second lifting shaft 2222 respectively enter the inside of the first spiral cylinder 2236 and the second spiral cylinder 2216. When the first spiral block 2225 and the second spiral block 2226 enter the inside of the first spiral cylinder 2236 and the second spiral cylinder 2216, the spiral stripes on the surfaces of the first spiral block 2225 and the second spiral block 2226 will correspond to the spiral grooves opened on the inner walls of the first spiral cylinder 2236 and the second spiral cylinder 2216. Therefore, as the first spiral block 2225 and the second spiral block 2226 continue to rise, the first spiral cylinder 2236 and the second spiral cylinder 2216 will rotate. Eventually, the first spiral cylinder 2236 and the second spiral cylinder 2216 will rotate by 90 degrees, so that the first limiting plate 2212 fixed on the outer surface of the first spiral cylinder 2236 and the second limiting plate 2217 fixed on the outer surface of the second spiral cylinder 2216 do not contact the first blade 2211 and the second blade 2213. At this time, there is no limit above the first blade 2211 and the second blade 2213. Then, control the first hydraulic rod 2102 to extend downward, and the second hydraulic rod 2219 contracts. Therefore, it can drive the severely worn first blade 2211 and the second blade 2213 below the first hydraulic rod 2102 to move downward synchronously. When the severely worn first blade 2211 and the second blade 2213 move downward to contact the first blade 2211 and the second blade 2213 to be replaced inside the replacement frame 2218, the severely worn first blade 2211 and the second blade 2213 will move upward, and the first blade 2211 and the second blade 2213 to be replaced will take the place of the original severely worn first blade 2211 and the second blade 2213. Thus, the purpose of replacing the first blade 2211 and the second blade 2213 can be achieved;

[0055] It should be understood here that, with the cooperation of the first one-way bearing 2210, the second one-way bearing 2214, the first rubber roller 2209 and the second rubber roller 2215, the first one-way bearing 2210 and the second one-way bearing 2214 can make the first rubber roller 2209 and the second rubber roller 2215 with fixed inner rings rotate only in one direction. By utilizing the characteristic of the large friction coefficient of the first rubber roller 2209 and the second rubber roller 2215, the first blade 2211 and the second blade 2213 can only move upward, thereby providing a limiting force for the first blade 2211 and the second blade 2213 to prevent the first blade 2211 and the second blade 2213 from moving downward. And the first limiting plate 2212 and the second limiting plate 2217 can respectively provide a limiting force in the upper position for the first blade 2211 and the second blade 2213, making it impossible for the first blade 2211 and the second blade 2213 to move upward. Thus, the fixation of the first blade 2211 and the second blade 2213 can be completed, and the purpose of cutting blocks can be effectively achieved.

[0056] Embodiment 3: Please refer to Figure 1 and Figure 15 , the present invention provides a technical solution: a dried bean curd cutting machine with adjustable knife distance. The present invention makes corresponding improvements to the technical problems mentioned in the background art. The collection mechanism 3 cooperates with the replacement mechanism 2, and the collection mechanism 3 can centrally process the replaced tools.

[0057] As a further limitation of the collection mechanism 3 of the present invention, the collection mechanism 3 includes two fourth threaded shafts 303. The outer surfaces of the two fourth threaded shafts 303 are respectively rotatably connected to the inner walls of the two support plates 1. A third stepping motor 304 is arranged on the right side of each fourth threaded shaft 303, and the output end of each third stepping motor 304 is fixedly connected to the right end of the fourth threaded shaft 303. A moving frame 301 is commonly threadedly connected to the outer surfaces of the two fourth threaded shafts 303. A force-bearing spring 307 is fixedly connected to the inner wall of the moving frame 301. A long shaft 308 is arranged in the inner cavity of the force-bearing spring 307. One end of the long shaft 308 close to the second stepping motor 2229 is fixedly connected to a push block 309. The outer surface of the long shaft 308 is slidably connected to the inside of the moving frame 301. The other end of the long shaft 308 away from the push block 309 is fixedly connected to a second bull's eye bearing 306. The back of the other support plate 1 is fixedly connected to a guiding plate 310. The front of one of the support plates 1 is fixedly connected to a collection box 302. The right side of the collection box 302 is fixedly connected to the left side of the support frame 2237. By setting the collection mechanism 3, the collection mechanism 3 can centrally collect the worn tools replaced. By setting the flipping unit 21, the replacement unit 22 and the collection mechanism 3, the problem that the tool replacement efficiency is relatively slow when the equipment is in use can be effectively avoided.

[0058] Please refer to Figure 15, a fixing seat 305 is fixedly connected to the right side surface of each support plate 1, and the upper surface of each fixing seat 305 is fixedly connected to the outer surface of the third stepping motor 304. By providing the fixing seat 305, the fixing seat 305 can provide a supporting force for the third stepping motor 304, making its operation more stable.

[0059] The specific implementation of this embodiment is as follows: When the severely worn first blade 2211 and second blade 2213 are pushed out by the first blade 2211 and second blade 2213 to be replaced, the third stepping motor 304 can be controlled to operate, thereby driving the fourth threaded shaft 303 to rotate. Utilizing the threaded connection relationship between the fourth threaded shaft 303 and the moving frame 301, the moving frame 301 can be driven to move to the right. During the process of the moving frame 301 moving to the right, it will push the already pushed-out first blade 2211 to move to the right until the first blade 2211 falls into the interior of the collection box 302 under the action of gravity. It should be understood here that when half of the size of the first blade 2211 moves above the collection box 302, the first blade 2211 will fall into the interior of the collection box 302 under the action of gravity. When the moving frame 301 moves in front of the guiding plate 310, the long shaft 308 and the second bull's-eye bearing 306 sliding inside the moving frame 301 will be pushed by the guiding plate 310, prompting the long shaft 308 to move forward. When the long shaft 308 moves forward, it will push the push block 309 to move forward synchronously until the right front corner of the push block 309 is flush with the front surface of the moving frame 301. At this time, the ejected second blade 2213 will be pushed forward from the position where it was ejected by the push block 309, and the second blade 2213 can also be pushed into the interior of the collection box 302. After all the second blades 2213 and first blades 2211 are centrally processed, the third stepping motor 304 can be controlled to reset. After the reset is completed, the first hydraulic rod 2102 is controlled to reset, driving the fixed frame 2204 and the lifting plate 2108 to move upward. When the two move upward, the positions of the first spiral block 2225 and the second spiral block 2226 remain unchanged. Therefore, the first spiral block 2225 and the second spiral block 2226 will gradually disengage from the contact relationship with the first spiral cylinder 2236 and the second spiral cylinder 2216, thereby driving the first spiral cylinder 2236 and the second spiral cylinder 2216 to reset. Thus, the first limiting plate 2212 and the second limiting plate 2217 can be rotated above the just-replaced first blade 2211 and second blade 2213 to limit the first blade 2211 and the second blade 2213. It should be understood here that since the first lifting shaft 2221 is fixed to the inner bottom wall of the lifting box 2220 through the fixing block 2223, when the first spiral cylinder 2236 moves upward, it will not drive the first lifting shaft 2221 and the first spiral block 2225 to move upward. And the second lifting shaft 2222 can also avoid the second lifting shaft 2222 and the second spiral block 2226 from rising along with the rising of the second spiral cylinder 2216 through the circular protrusion on the surface.
