Description

Technical Field

[0001] This invention relates to the field of dried bean curd processing technology, and in particular to a fine cutting device for dried bean curd using elastic pressure rollers. Background Technology

[0002] The flexible pressure roller coordinated bean curd cutting device is a mechanical device used in the production and processing of bean curd. It is designed to cut the formed bean curd according to preset specifications. The device generally consists of several key parts, including a conveying mechanism, a flexible pressure roller assembly, a cutting blade assembly, and a support frame. After long-term use, the blade will wear down. The worn blade can no longer perform "shearing cuts" and instead exerts a "compression-tearing" effect on the bean curd, resulting in irregular burrs or fiber fraying on the cut edges. In severe cases, the edges of the pieces will be "serrated," which does not meet the appearance standards of food processing at all. When repairing the blade, the blade is only "passively repaired" after defective products are found. In essence, it is a "lagging response" to the blade wear process. When defective products are found, at least hundreds to thousands of pieces of bean curd have already undergone "substandard cutting," which will lead to an increased scrap rate and waste of raw materials.

Detailed Implementation

[0026] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments. Example

[0029] Reference Figures 1-4This is the first embodiment of the present invention. This embodiment provides a fine bean curd cutting device with elastic pressure rollers. The fine bean curd cutting device with elastic pressure rollers includes a cutting component 100, including a support frame 101. A conveyor belt 102 is provided on the support frame 101. A pressure roller 103 is provided above the conveyor belt 102. An elastic pressure adjustment mechanism is provided above the pressure roller 103 to adjust the pressure of the pressure roller 103. A movable frame 104 is provided on the top of the support frame 101. A cutter 105 is fixed on one side of the movable frame 104. The movable frame 104 is used to drive the cutter 105 to move up and down, so that the bean curd can be cut by the cutter 105. This is the prior art, and this solution will not be described in detail. Moreover, those skilled in the art can clearly understand the working principle.

[0030] The grinding assembly 200 is located on the top of the support frame 101 and includes a grinding component 201. The grinding component 201 includes a slide rail 2011 fixed to the top of the support frame 101. A movable frame 2012 is provided inside the slide rail 2011. The movable frame 2012 is T-shaped and slidably connected to the slide rail 2011. A movable block 2013 is inserted into the movable frame 2012. A reciprocating roller 2014 is rotatably connected inside the movable block 2013. The reciprocating roller 2014 is rotatably connected to the movable block 2013 through a bearing. A movable rod 2015 is sleeved on the outside of the reciprocating roller 2014. A fixed shaft 2019 is fixed inside the movable rod 2015 and meshes with the reciprocating roller 2014. A grinding tool 2016 is fixed on one side of the movable rod 2015. The initial height of the grinding tool 2016 is lower than the height of the cutter 105 at its highest point.

[0031] When the cutter 105 has been used for a long time and shows slight wear, the movable frame 2012 will move towards the cutter 105 and move the grinder 2016 below the cutter 105. Then, the movable block 2013 will move the grinder 2016 upward and bring it into contact with the cutter 105. At this time, the reciprocating roller 2014 will rotate and drive the movable rod 2015 and the grinder 2016 to move back and forth through the fixed shaft 2019. This allows the cutter 105 to be repaired in time by the grinder 2016, avoiding a large number of defective products due to the failure to repair the wear of the cutter 105 in time.

[0032] A position sensor (not shown in the figure) is provided on the movable frame 2012. The position sensor is used to sense the position of the movable frame 2012 and can control the start and stop state of the movable frame 104. When the movable frame 2012 is in the initial position, the movable frame 104 is in the working state and drives the cutter 105 to move up and down. When the movable frame 2012 moves in the direction of the cutter 105, the position sensor can control the movable frame 104 to stop working and make the movable frame 104 drive the cutter 105 to the highest position. Then the grinder 2016 can move to below the cutter 105. The working principle of the position sensor is the prior art. This solution will not elaborate on it. Moreover, those skilled in the art can clearly understand the working principle. The position sensor is only the preferred solution in this solution. Any method that can achieve the above effect is acceptable.

[0033] There are two slide rails 2011, two movable frames 2012, and two movable blocks 2013, located on the top sides of the support frame 101 respectively. The top of each movable block 2013 is fixed with a positioning block, and a positioning column is fixed between the two positioning blocks. The top of the movable rod 2015 is fixed with a stabilizing block, and the positioning column is movably connected to the stabilizing block. The two work together to position the movable rod 2015 and prevent the movable rod 2015 from tilting when it moves. Example

[0034] Reference Figures 3-5 and Figure 9 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0035] Specifically, the grinding assembly 200 also includes a pusher 202. There are two sets of pushers 202, located on the top two sides of the support frame 101 respectively, and corresponding to the grinding assembly 201. The pusher 202 includes a fixing frame 2021 fixed to the top of the support frame 101. An airbag 2022 is provided inside the fixing frame 2021. The fixing frame 2021 is used to install and position the airbag 2022. When gas is injected into the airbag 2022, it can expand and collect the gas.

[0036] An air outlet pipe 2023 is fixed to the top of the airbag 2022, and the air outlet pipe 2023 is connected to the airbag 2022. A corrugated pipe 2024 is fixed to one side of the movable frame 2012. The corrugated pipe 2024 is telescopic and elongated, and one end is fixed to the inner wall of the slide rail 2011. A connecting pipe 2025 is fixed to the end of the corrugated pipe 2024. The two ends of the corrugated pipe 2024 are connected to the movable frame 2012 and the connecting pipe 2025 respectively. The connecting pipe 2025 is connected to the air outlet pipe 2023 through a flexible hose. The movable frame 2012 and the movable block 2013 fit tightly together, and there will be no gas leakage.

[0037] When the gas inside the airbag 2022 enters the air outlet pipe 2023, it is delivered to the connecting pipe 2025 and the corrugated pipe 2024 through the hose. At this time, the corrugated pipe 2024 delivers the gas to the movable frame 2012. The gas inside the movable frame 2012 cannot be discharged, which pushes the movable frame 2012 to move. This causes the movable block 2013 and the grinder 2016 to move through the movable frame 2012. When the grinder 2016 moves below the cutter 105, the gas pushes the movable block 2013 upward. This causes the grinder 2016 to move upward and contact the blade of the cutter 105 through the movable block 2013. The gas continuously applies a pushing force to the movable block 2013, ensuring that the grinder 2016 is always in contact with the cutter 105.

[0038] A stabilizing rod is fixed to one side of the air outlet pipe 2023, and a stabilizing groove is provided on the fixing frame 2021. The stabilizing rod slides in the stabilizing groove. The two work together to position the air outlet pipe 2023 and prevent it from shifting when moving.

[0039] Specifically, a sealing cover 2026 is fixed on one side of the movable block 2013, and a diversion pipe 2027 is fixed at the bottom of the sealing cover 2026. The two ends of the diversion pipe 2027 are made of rigid material, and the middle part is made of soft material, so that the diversion pipe 2027 can adapt to the up and down movement of the movable block 2013. The two ends are connected to the sealing cover 2026 and the connecting pipe 2025 respectively. A force-bearing block 2028 is fixed on the outside of the reciprocating roller 2014. There are multiple force-bearing blocks 2028, which are evenly distributed in a ring on the outside of the reciprocating roller 2014. An air outlet is opened at the top of the sealing cover 2026.

[0040] When the grinder 2016 contacts the cutter 105, the gas inside the connecting pipe 2025 enters the sealing cover 2026 through the diversion pipe 2027, and pushes the force block 2028 and the reciprocating roller 2014 to rotate, which in turn drives the grinder 2016 to move back and forth through the reciprocating roller 2014.

[0041] Specifically, the grinding assembly 200 also includes a limiting component 203, which includes a limiting block 2031. A slot 2013-1 is provided on the movable block 2013, and the limiting block 2031 is located in the slot 2013-1. A limiting groove 2032 is fixed on one side of the movable frame 2012. The limiting block 2031 engages with the limiting groove 2032. Through the cooperation of the two, the movable block 2013 is limited, so that the movable block 2013 will not move upward before the grinder 2016 moves below the cutter 105. The bottom of one side of the limiting block 2031 is inclined.

[0042] A first spring 2033 is fixed on one side of the limiting block 2031. The first spring 2033 is used to apply a pushing force to the limiting block 2031, so that the limiting block 2031 and the limiting groove 2032 are engaged more securely.

[0043] A pressing rod 2034 is fixed on one side of the slide rail 2011. The pressing rod 2034 is L-shaped and is on the same horizontal line as the limiting groove 2032. When the grinder 2016 moves to below the cutter 105, the pressing rod 2034 will insert into the limiting groove 2032 and push the limiting block 2031 to separate from the limiting groove 2032, thereby releasing the restriction on the movable block 2013 and enabling the movable block 2013 to drive the grinder 2016 to move upward.

[0044] Specifically, the grinding assembly 200 also includes an inflation component 204, which includes an air inlet pipe 2041 fixed to one side of the airbag 2022. The air inlet pipe 2041 is connected to the airbag 2022 and fixed to the fixing frame 2021. A piston 2042 is provided inside the air inlet pipe 2041. An air inlet hole 2042-1 is provided on the piston 2042. A stop block 2043 is provided at the bottom of the air inlet hole 2042-1.

[0045] The stop block 2043 is hinged to the bottom of the piston 2042 via a hinge seat, and a torsion spring is provided on the hinge seat. The torsion spring can apply an upward torsional force to the stop block 2043. Although this connection method is not shown in the figure, it is existing technology. Any connection method that can hinge the stop block 2043 to the bottom of the piston 2042, give the stop block 2043 an upward torsional force, and fit against the bottom of the piston 2042 is acceptable.

[0046] When piston 2042 moves downward, stop block 2043 blocks air inlet 2042-1. At this time, the gas generated by piston 2042 moving downward will enter the airbag 2022, thereby injecting gas into the airbag 2022 and causing the airbag 2022 to inflate. When piston 2042 moves upward, stop block 2043 will open downward under the force of airflow. At this time, airflow will enter below piston 2042. As piston 2042 moves downward again, gas can be delivered to the airbag 2022 again.

[0047] A fixing post 2044 is fixed to the top of the piston 2042. The top end of the fixing post 2044 extends to the outside of the intake pipe 2041. A fixing plate 2045 is fixed to the top of the fixing post 2044. A second spring 2046 is fixed to the bottom of the fixing plate 2045. The second spring 2046 is used to apply a pushing force to the fixing plate 2045 so that it can return to its original position after moving down. A threaded post 2047 is connected to the fixing post 2044 internally. A pressure block 2048 is fixed to one side of the movable frame 104.

[0048] When the movable frame 104 moves the cutter 105 downward, it will cause the pressure block 2048 to contact the threaded post 2047, and push the threaded post 2047 and the fixed post 2044 downward. This will cause the fixed post 2044 to drive the piston 2042 downward. After the movable frame 104 moves upward and causes the pressure block 2048 to separate from the threaded post 2047, the second spring 2046 can push the fixed plate 2045 and the fixed post 2044 upward, and the fixed post 2044 can drive the piston 2042 upward.

[0049] By repeating this process, gas can be continuously injected into the airbag 2022. As the cutter 105 is used continuously, the airbag 2022 will continue to expand. When the airbag 2022 expands to a certain extent, it means that the cutter 105 has been used for a long time and has experienced slight wear. At this time, the gas injected into the airbag 2022 will be released outward, and the gas will cause the grinder 2016 to grind the cutter 105. This allows the cutter 105 to be ground in time when slight wear occurs, preventing the wear of the cutter 105 from becoming more severe and increasing the number of defective dried bean curd products.

[0050] Furthermore, using the number of times the cutter 105 is used as a criterion for judging the frequency of regrinding the cutter 105 can more accurately grasp the frequency of regrinding the cutter 105 and avoid over-regrinding or untimely regrinding.

[0051] The threaded column 2047 can be rotated to move it up or down. When the threaded column 2047 moves down, the pressure block 2048 will push the threaded column 2047 down later, and the stroke of the piston 2042 will be shortened. This will inject a small amount of gas into the air bag 2022 and make the air bag 2022 expand more slowly. This will reduce the frequency of regrinding the cutter 105, which is suitable for use when the cutter 105 is new.

[0052] When the threaded column 2047 moves upward, the pressure block 2048 will push the threaded column 2047 downward earlier, and make the downward stroke of the piston 2042 longer, thereby injecting more gas into the air bag 2022 and increasing the expansion speed of the air bag 2022. This allows the cutting blade 105 to be refurbished more frequently, which is beneficial for the cutting blade 105 after long-term use and multiple refurbishments.

[0053] A baffle 2049 is provided at one end of the air intake pipe 2041 located inside the airbag 2022. The connection method between the baffle 2049 and the end of the air intake pipe 2041 is the same as the connection method between the baffle 2043 and the piston 2042.

[0054] When piston 2042 moves downward, it pushes baffle 2049 open through airflow, allowing gas to enter the airbag 2022. When piston 2042 moves upward, baffle 2049 closes, thus preventing gas leakage from the airbag 2022. Example

[0055] Reference Figure 3 , Figure 6 and Figure 8 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0056] Specifically, the grinding assembly 200 also includes a first sealing component 205, which includes a fixing ring 2051 fixed inside the air outlet pipe 2023. A baffle plate 2052 is provided on the top of the fixing ring 2051. The connection method between the baffle plate 2052 and the fixing ring 2051 is the same as that of the stop block 2043. The baffle plate 2052 has a downward torsional force. The baffle plate 2052 blocks the gas inside the airbag 2022 to prevent gas leakage before the airbag 2022 has inflated to the specified degree.

[0057] A baffle 2053 is inserted into the exhaust pipe 2023. The bottom of the baffle 2053 contacts the interceptor plate 2052 and is used to block the interceptor plate 2052, so that the interceptor plate 2052 cannot be opened upward by the thrust of the gas.

[0058] A push rod 2054 is fixed to the top wall of the fixed frame 2021. A force groove 2053-1 is provided on the baffle 2053. The inner wall of the force groove 2053-1 is inclined. When the airbag 2022 is inflated, it will drive the air outlet pipe 2023 to move upward. When the airbag 2022 inflates to a sufficient height, the push rod 2054 is inserted into the force groove 2053-1 and squeezes the inclined surface inside the force groove 2053-1. Through the cooperation of the two, the baffle 2053 is moved, so that the baffle 2053 is separated from the interceptor plate 2052. Then the interceptor plate 2052 can be opened by the thrust of the gas and the gas can flow outward.

[0059] The connection between the stop lever 2053 and the air outlet pipe 2023 is sealed.

[0060] Specifically, a stabilizing frame 2055 is fixed to one side of the air outlet pipe 2023, and a third spring 2056 is fixed to one side of the baffle 2053.

[0061] The stop lever 2053 is movably connected to the stabilizer frame 2055. One end of the third spring 2056 is fixed to the inner wall of the stabilizer frame 2055. When the air outlet pipe 2023 moves downward and the force groove 2053-1 separates from the push rod 2054, the stop lever 2053 can be pushed back to its original position by the third spring 2056.

[0062] The top of the stop lever 2053 is inclined. If the stop lever 2053 enters the air outlet pipe 2023 first, and the interceptor plate 2052 closes downwards, the interceptor plate 2052 will squeeze the inclined surface of the top of the stop lever 2053 when it closes downwards, and push the stop lever 2053 to make way, so that the interceptor plate 2052 can close smoothly. Therefore, the elastic force of the torsion spring on the interceptor plate 2052 is greater than the elastic force of the third spring 2056.

[0063] Specifically, the grinding assembly 200 also includes a second sealing component 206, which includes a positioning ring 2061 fixed inside the diversion pipe 2027. A sealing plate 2062 is provided on the top of the positioning ring 2061. The sealing plate 2062 is used to seal the inside of the diversion pipe 2027 so that gas will not enter the sealing cover 2026 through the diversion pipe 2027 before the grinder 2016 moves below the cutter 105.

[0064] A stabilizing column is fixed to the top of the sealing plate 2062, and a stabilizing frame is fixed to the inner wall of the diversion pipe 2027. The stabilizing column is movably connected to the stabilizing frame, and a sixth spring is fixed to the bottom of the stabilizing frame to apply a downward pushing force to the sealing plate 2062.

[0065] A limiting rod 2063 is inserted into the diverter pipe 2027. The limiting rod 2063 is used to limit the sealing plate 2062 so that it will not be opened by the thrust of the airflow.

[0066] The top of the movable frame 2012 is fixed with a fixing rod 2064, which is U-shaped. The limiting rod 2063 has a groove 2063-1, and the inner wall of the groove 2063-1 is inclined.

[0067] When the movable block 2013 drives the grinder 2016 to move upward and comes into contact with the cutter 105, the fixed rod 2064 will insert into the groove 2063-1 and press against the inner wall of the groove 2063-1. Through the cooperation of the two, the limiting rod 2063 will move, causing the limiting rod 2063 to separate from the sealing plate 2062, thus releasing the restriction on the sealing plate 2062 and allowing the sealing plate 2062 to be pushed upward by the airflow.

[0068] Specifically, a positioning frame 2065 is fixed on one side of the diversion pipe 2027, and a limiting rod 2063 is movably connected to the positioning frame 2065. A fourth spring 2066 is fixed on one side of the limiting rod 2063. When the movable block 2013 moves downward and the groove 2063-1 is separated from the fixed rod 2064, the limiting rod 2063 can be pushed into the diversion pipe 2027 by the fourth spring 2066 and reset.

[0069] The top side of the limiting rod 2063 is inclined. If the limiting rod 2063 resets first and the sealing plate 2062 moves down afterward, the sealing plate 2062 can push the top inclined surface of the limiting rod 2063 to make way. Therefore, the elastic force of the sixth spring is greater than that of the fourth spring 2066.

[0070] Specifically, a fifth spring 2017 is fixed on one side of the movable frame 2012, and the other end of the fifth spring 2017 is fixed to the inner wall of the slide rail 2011. When the gas inside the airbag 2022 is released and the thrust of the gas is lost, the movable block 2013 will move downward by its own weight, and at the same time the fifth spring 2017 will push the movable frame 2012 to reset.

[0071] A slider 2018 is fixed to the inner wall of the movable frame 2012, and a groove 2013-2 is provided on the movable block 2013. The slider 2018 slides in the groove 2013-2, and the two work together to position the stroke of the movable block 2013 moving up and down.

[0072] When in use, the movable frame 104 drives the cutter 105 to move up and down, which can cut the dried bean curd. When the movable frame 104 drives the cutter 105 to move down, it will cause the pressure block 2048 to contact the threaded post 2047, and push the threaded post 2047 and the fixed post 2044 to move down. This will cause the fixed post 2044 to drive the piston 2042 to move down. The gas generated by the piston 2042 moving down will enter the air bag 2022, which will inject gas into the air bag 2022 and cause the air bag 2022 to expand.

[0073] When the airbag 2022 inflates, it will drive the air outlet pipe 2023 to move upward. When the airbag 2022 inflates to a sufficient height, the push rod 2054 is inserted into the force groove 2053-1 and squeezes the inclined surface inside the force groove 2053-1. Through the cooperation of the two, the baffle 2053 is moved, so that the baffle 2053 is separated from the interceptor plate 2052. Then the interceptor plate 2052 can be opened by the thrust of the gas and the gas can flow outward.

[0074] When the gas inside the airbag 2022 enters the air outlet pipe 2023, it is delivered to the connecting pipe 2025 and the bellows 2024 through the hose. At this time, the bellows 2024 delivers the gas to the movable frame 2012. The gas inside the movable frame 2012 cannot be discharged, which pushes the movable frame 2012 to move. This, in turn, drives the movable block 2013 and the grinder 2016 to move. When the grinder 2016 moves to the cutter 1... After 05, the extrusion rod 2034 will be inserted into the limiting groove 2032 and push the limiting block 2031 to separate from the limiting groove 2032, thereby releasing the restriction on the movable block 2013. At this time, the gas will push the movable block 2013 to move upward, and the shaving tool 2016 will be driven upward to contact the cutting edge of the cutter 105 through the movable block 2013. The gas will continuously apply a pushing force to the movable block 2013, so that the shaving tool 2016 can always contact the cutting edge 105.

[0075] At the same time, the fixing rod 2064 will be inserted into the groove 2063-1 and squeeze the inner wall of the groove 2063-1. Through the cooperation of the two, the limiting rod 2063 will move, so that the limiting rod 2063 will separate from the sealing plate 2062, and the restriction on the sealing plate 2062 will be released. This allows the sealing plate 2062 to be pushed upward by the airflow and open. The gas inside the connecting pipe 2025 will enter the sealing cover 2026 through the diversion pipe 2027 and push the force block 2028 and the reciprocating roller 2014 to rotate.

[0076] The reciprocating roller 2014, in cooperation with the fixed shaft 2019, drives the movable rod 2015 and the grinder 2016 to move back and forth. The grinder 2016 can then repair the cutter 105 in a timely manner, keeping the blade sharp and preventing it from entering a "squeezing-tearing" wear state. This ensures that the cut edges of the dried bean curd are always flat, and there are almost no burrs, serrations, or other defects, greatly reducing the scrap rate.

Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
