Description

Technical Field

[0001] The present invention relates to the technical field of fish bone crushing equipment, and more particularly to a fish bone crushing equipment for processing fish bone calcium powder. Background Art

[0002] Fish bone calcium powder is a high-quality natural calcium source, which is mainly refined from the remaining fish bones in the fish processing process through processes such as high temperature, saponification, degreasing, degumming, and deodorization. This calcium powder not only has high purity and good safety, but also its calcium-phosphorus ratio meets the human body's needs and is easily absorbed and utilized by the human body. Compared with traditional chemically synthesized calcium agents, fish bone calcium powder has higher bioavailability and better calcium supplementation effects. It can not only be used as a raw material for health products to make products such as calcium powder capsules, chewable tablets or sugar-coated tablets to meet people's calcium supplementation needs, but also be used as a food additive to increase the calcium content of food. In addition, fish bone calcium powder also has unique biological functions and advantages, such as promoting bone growth and enhancing immunity, so it has attracted much attention and favor.

[0003] The patent document with Chinese Publication No. CN115837301A discloses a fish bone crushing equipment for processing fish bone powder, including a support base. A vertical frame one is fixedly installed on the upper surface of the support base. A end cap is fixedly sleeved at the top of the vertical frame one. A feeding port is arranged on the upper part of one side end cap. The outer surface of the end cap is movably sleeved with a rotating cylinder. A rotating tooth is fixedly sleeved on one side of the outer surface of the rotating cylinder. A motor one meshing with the rotating tooth is fixedly installed on one side of the upper surface of the support base. This fish bone crushing equipment drives the hammer head to rotate through a rotating shaft. The hammer head is movably sleeved with a guide rod. When the electromagnet is energized, it has a magnetic attraction effect on the hammer head, preventing the hammer head from immediately falling when it rotates from the top and tilts downward. When the hammer head rotates to the vertical downward position, the electromagnet is powered off, and the hammer head directly falls to impact the fish bone. After the hammer head falls, the electromagnet is immediately energized to prevent the subsequent rotating hammer head from slipping. The hammer head has a large self-weight, and the impact crushing effect on the fish bone is better.

[0004] In the fish bone crushing equipment in the above patent document, the hammer head is driven to rotate by a rotating shaft, so that the hammer head rotates and impacts the falling fish bone at the same time, and then the hammer head breaks the fish bone. However, in the process of breaking the fish bone by the hammer head in the above fish bone crushing equipment, only the rotation of the hammer head can be used to break the fish bone, resulting in low crushing efficiency. And the hammer head is directly fixed on the rotating shaft, making the moving path of the hammer head unable to move. When the fish bones accumulate to a certain amount, the resistance received by the hammer head increases. When the resistance reaches a certain value, it is extremely easy to cause the connecting part between the hammer head and the rotating shaft to bend or break, resulting in damage to the hammer head. Therefore, a fish bone crushing equipment for processing fish bone calcium powder is proposed. Summary of the Invention

[0005] To solve the above problems, a fish bone crushing device for processing fish bone calcium powder is provided. The rotation of the installation shaft drives the synchronous rotation of the fixed sleeve. At the same time, the fixed sleeve drives the installation rod and the limit rod fixed thereon to rotate synchronously. Then, the installation rod and the limit rod drive the vertical rod to rotate around the central axis of the fixed sleeve. When the vertical rod rotates, it moves away from the fixed sleeve under the action of centrifugal force, so that the vertical rod drives the grinding roller installed at the bottom to contact the side wall of the grinding disc. The grinding roller and the grinding disc cooperate to grind the fish bones into powder. This solves the problem that the grinding roller cannot move, resulting in easy damage of the grinding roller. Thus, the service life of the grinding roller is improved.

A plurality of installation rods are equidistantly fixed around the central axis of the fixed sleeve outside the fixed sleeve. A plurality of limit rods are fixed at the top outside the fixed sleeve near the installation rods. The number of limit rods corresponds to that of the installation rods;

[0008] One side of the fixed sleeve is movably provided with a vertical rod that can move along the central axis direction of the installation rod and the limit rod. A grinding roller that can rotate around the central axis of the vertical rod is installed at the bottom of the vertical rod;

[0009] A limiting mechanism for limiting is fixed at one end of the installation rod and the limit rod away from the fixed sleeve.

[0010] As a technical solution of the present invention, a spring for pushing the vertical rod is installed outside the installation rod; a limit hole that can be slidably matched with the limit rod is opened at the top of the vertical rod; an installation hole is opened at the bottom of the vertical rod near the limit hole, and the installation hole is slidably matched with the installation rod.

[0011] As a technical solution of the present invention, a feeding mechanism is fixed outside the installation shaft. A plurality of inclined feeding blades are equidistantly arranged around the central axis of the feeding mechanism. The bottom of the feeding blade can contact the bottom of the grinding disc.

[0012] As a technical solution of the present invention, the limiting mechanism includes a limiting block fixed at the top and bottom of the limit rod and the installation rod away from the fixed sleeve respectively. An anti-collision block for anti-collision is fixed at one end of the limiting block.

[0013] As a technical solution of the present invention, a cylinder is fixed on the top of the support base, and a fairing for guiding the air flow inside it is fixed on the top of the cylinder. A rotatable rotating shaft is installed at the center of the fairing, and a rotatable fan blade is installed at the bottom end of the rotating shaft. The fan blade is used to drive the air inside the cylinder to flow upward.

[0014] As a technical solution of the present invention, a discharge port for outputting the ground fish bones into powder is provided on one side of the fairing.

[0015] As a technical solution of the present invention, a limiting frame for limiting the rotating shaft is installed inside the fairing. The rotating shaft can pass through the center of the limiting frame, and the rotating shaft is rotatably arranged with the limiting frame.

[0016] As a technical solution of the present invention, a feeding port is opened on one side wall of the cylinder, and a feeding device for adding fish bones into it is arranged on one side of the cylinder. The bottom of the feeding device can be fixedly connected to the feeding port, and the feeding device can be communicated with the cylinder.

[0017] As a technical solution of the present invention, the feeding device includes a crushing feeding box that can be connected to the feeding port. An actively rotating crushing roller is installed inside the input end of the crushing feeding box; a driven transmission crushing roller that can mesh with it is rotatably arranged on one side of the inside of the input end of the crushing feeding box close to the actively rotating crushing roller; the central axis of the actively rotating crushing roller is parallel and at the same height as the central axis of the driven transmission crushing roller.

[0018] As a technical solution of the present invention, a driving gear is arranged on one side of the crushing feeding box. The driving gear is fixed to the extending end of the actively rotating crushing roller. A driven gear is arranged on one side of the crushing feeding box close to the driving gear. The driven gear is fixed to the output end of the driven transmission crushing roller, and the driving gear can mesh with the driven gear.

[0019] The beneficial effects of the present invention compared with the prior art are:

[0020] 1. In this application, the rotation of the installation shaft drives the synchronous rotation of the fixed sleeve. At the same time, the fixed sleeve drives the installation rod and the limiting rod fixed on it to rotate synchronously. Then, the installation rod and the limiting rod drive the vertical rod to rotate around the central axis of the fixed sleeve. When the vertical rod rotates, it moves away from the fixed sleeve under the action of centrifugal force, so that the vertical rod drives the grinding roller installed at the bottom to contact the side wall of the grinding disc. The cooperation between the grinding roller and the grinding disc realizes the grinding of the fish bones into powder. It solves the problem that the grinding roller cannot move, resulting in easy damage of the grinding roller. Thus, the service life of the grinding roller is improved.

[0021] 2. This application utilizes a spring to push the vertical rod, enabling it to move along the central axes of the mounting rod and the limiting rod through the mounting holes and the limiting holes, thereby solving the problem that when the vertical rod grinds fish bones through the grinding roller, insufficient thrust of the grinding roller leads to the inability to grind the fish bones into powder. Thus, the grinding efficiency of the crushing equipment is improved.

[0022] 3. This application utilizes the rotation of the mounting shaft to drive the feeding mechanism to rotate synchronously. While the feeding mechanism rotates, it drives the feeding blades to rotate synchronously. When the feeding blades rotate, the fish bone raw materials at the bottom of the grinding disc will be pushed upward, separating the fish bone raw materials from the grinding disc. At the same time, the feeding blades push the fish bone raw materials towards the side wall of the grinding disc, enabling the fish bone raw materials to gather at a position close to the side wall inside the grinding disc. Thus, the grinding efficiency of the grinding roller and the grinding disc in cooperation for fish bones is improved. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0035] In order to further understand the features, technical means, specific purposes and functions achieved by the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0036] See Figures 1 - 11 As shown, a fish bone crushing device for processing fish bone calcium powder includes a support base 1, a grinding disc 11 arranged on the top of the support base 1, a grinding mechanism 13 arranged inside the grinding disc 11 for grinding fish bones into powder, and a mounting shaft 16 arranged inside the grinding disc 11 for driving the grinding mechanism 13 to rotate. The mounting shaft 16 is vertically installed at the center inside the grinding disc 11;

[0037] The grinding mechanism 13 includes a fixed sleeve 131 fixed at a position close to the top outside the mounting shaft 16. A plurality of mounting rods 1311 are equidistantly fixed around the center axis of the outside of the fixed sleeve 131. A plurality of limiting rods 1312 are fixed at the top outside the fixed sleeve 131 close to the mounting rods 1311. The number of the limiting rods 1312 corresponds to that of the mounting rods 1311;

[0038] A vertical rod 132 that can move along the central axis directions of the mounting rods 1311 and the limiting rods 1312 is movably arranged on one side of the fixed sleeve 131. A grinding roller 1323 that can rotate around the central axis of the vertical rod 132 is installed at the bottom of the vertical rod 132;

[0039] Limiting mechanisms 14 for limiting are fixed at the ends of the mounting rods 1311 and the limiting rods 1312 far from the fixed sleeve 131.

[0040] A first servo motor 18 for driving the mounting shaft 16 to rotate is further provided at the bottom of the support base 1. The output end of the first servo motor 18 is fixedly connected to the bottom end of the mounting shaft 16. When the first servo motor 18 drives the mounting shaft 16 to rotate, the mounting shaft 16 can drive the fixed sleeve 131 fixed to its top to rotate synchronously. Then, the fixed sleeve 131 drives the vertical rod 132 to rotate synchronously around the central axis of the fixed sleeve 131 through the mounting rod 1311 and the limiting rod 1312. While the vertical rod 132 rotates around the central axis of the fixed sleeve 131, the vertical rod 132 moves along the central axes of the mounting rod 1311 and the limiting rod 1312 under the action of centrifugal force and approaches the side wall of the grinding disc 11, so that the vertical rod 132 drives the grinding roller 1323 at the bottom to cooperate with the side wall of the grinding disc 11 to grind the fish bone raw material. This avoids the easy damage of the grinding roller 1323 caused by its inability to move, thereby improving the service life of the grinding roller 1323.

[0041] See Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown in, a spring 15 for pushing the vertical rod 132 is installed outside the mounting rod 1311; a limiting hole 1322 capable of slidingly cooperating with the limiting rod 1312 is provided at the top of the vertical rod 132; a mounting hole 1321 is provided at the bottom of the vertical rod 132 near the limiting hole 1322, and the mounting hole 1321 can slidingly cooperate with the mounting rod 1311.

[0042] To ensure effective grinding between the grinding roller 1323 and the grinding disc 11. The pushing vertical rod 132 can move along the central axes of the mounting rod 1311 and the limiting rod 1312 through the mounting hole 1321 and the limiting hole 1322. So that the grinding roller 1323 can provide sufficient grinding force, thereby enabling the grinding roller 1323 to effectively grind the fish bones. This avoids the insufficient thrust of the grinding roller 1323 resulting in the inability to grind the fish bones into powder. Thus, the grinding efficiency of the crushing equipment is improved.

[0043] See Figure 5 and Figure 6 As shown in and, a feeding mechanism 17 is fixed outside the mounting shaft 16. A plurality of inclined feeding blades 171 are equidistantly arranged around the central axis of the feeding mechanism 17, and the bottom of the feeding blade 171 can contact the bottom of the grinding disc 11.

[0044] The rotation of the installation shaft 16 drives the feeding mechanism 17 to rotate synchronously. While the feeding mechanism 17 rotates, it drives the feeding blades 171 to rotate synchronously. When the feeding blades 171 rotate, the bottom of the feeding blades 171 will push the fish bone raw materials at the bottom of the grinding disc 11 upward, separating the fish bone raw materials from the grinding disc 11. At the same time, the feeding blades 171 push the fish bone raw materials towards the side wall of the grinding disc 11, enabling the fish bone raw materials to gather at a position near the side wall inside the grinding disc 11. Thus, the grinding efficiency of the grinding roller 1323 and the grinding disc 11 in cooperation with each other for grinding fish bones is improved. Meanwhile, while the feeding blades 171 push the fish bone raw materials upward, the fish bone raw materials that have been ground into powder can be suspended inside the cylinder body 2, facilitating the discharge of the fish bone raw materials ground into powder.

[0045] See Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown in

[0046] One end of the limiting block 141 is fixed with an anti-collision block 142 for anti-collision, and the top and bottom of the limiting mechanism 14 are respectively fixed to one end of the limiting rod 1312 and the mounting rod 1311 away from the fixed sleeve 131.

[0047] See Figure 1 , Figure 2 , Figure 3 , Figure 8 , Figure 9 and Figure 10 As shown in

[0048] At the center of the top end of the fairing 3, a second servo motor 4 capable of driving the rotation of the rotating shaft 41 is provided, and the output end of the second servo motor 4 can be fixedly connected to the top end of the rotating shaft 41. When the second servo motor 4 drives the rotation of the rotating shaft 41, the rotating shaft 41 can drive the fan blades 5 to rotate synchronously. When the fan blades 5 rotate, the fan blades 5 can drive the fish bone raw materials ground into powder and floating inside the cylinder body 2 to move upward and enter the inside of the fairing 3.

[0049] See Figure 1 , Figure 2 , Figure 3 and Figure 9 As shown, a discharge port 31 capable of discharging the ground fish bones into powder is provided on one side of the fairing 3.

[0050] When the powdered fish bone raw materials are fed into the inside of the fairing 3, the powdered fish bone raw materials can be smoothly discharged through the discharge port 31 provided on one side of the fairing 3. Effectively prevent the powdered fish bone raw materials from accumulating excessively inside the cylinder body 2, thereby ensuring that the grinding process is not affected and maintaining the later grinding efficiency.

[0051] See Figure 3 , Figure 8 and Figure 9 As shown, a limit frame 32 for limiting the rotating shaft 41 is installed inside the fairing 3, and the rotating shaft 41 can pass through the center of the limit frame 32, and the rotating shaft 41 is rotatably arranged with the limit frame 32.

[0052] To ensure the stability of the rotating shaft 41. By fixing the limit frame 32 inside the fairing 3, and then rotatably installing the rotating shaft 41 at the center of the limit frame 32 and the central axis of the rotating shaft 41 is longitudinally coincident with the central axis of the limit frame 32. Effectively avoid the deviation of the rotating shaft 41 during rotation, thereby ensuring the stability of the rotating shaft 41.

[0053] See Figure 1 , Figure 3 and Figure 8 As shown, a feed inlet 21 is opened on one side wall of the cylinder body 2, and a feeding device 6 for adding fish bones to its inside is provided on one side of the cylinder body 2. The bottom of the feeding device 6 can be fixedly connected to the feed inlet 21, and the feeding device 6 can communicate with the cylinder body 2.

[0054] By providing the feeding device 6 on one side of the cylinder body 2 and fixedly connecting the output end of the feeding device 6 to the feed inlet 21, the feeding device 6 can communicate with the inside of the cylinder body 2, so that the fish bones can be added to the inside of the cylinder body 2 through the feeding device 6.

[0055] See Figure 1 , Figure 2 , Figure 3 , Figure 8And Figure 11 As shown, the feeding device 6 includes a crushing and feeding box 61 capable of connecting to the feeding port 21. Inside the input end of the crushing and feeding box 61, a rotatable active crushing roller 62 is installed; inside the input end of the crushing and feeding box 61, a driven transmission crushing roller 63 capable of meshing with it is rotatably arranged on one side close to the active crushing roller 62; the central axis of the active crushing roller 62 is parallel to and at the same height as the central axis of the driven transmission crushing roller 63.

[0056] To improve the grinding efficiency of fish bones, the active crushing roller 62 and the driven transmission crushing roller 63 capable of rotating synchronously clockwise and counterclockwise are installed inside the input end of the crushing and feeding box 61. When the active crushing roller 62 and the driven transmission crushing roller 63 rotate, they can break the fish bones into small particles, making the fish bones more convenient for grinding.

[0057] See Figure 11 As shown, on one side of the crushing and feeding box 61, an active transmission gear 621 is provided, and the active transmission gear 621 is fixed to the extended end of the active crushing roller 62. On one side of the crushing and feeding box 61 close to the active transmission gear 621, a driven gear 631 is provided, and the driven gear 631 is fixed to the output end of the driven transmission crushing roller 63. The active transmission gear 621 can mesh with the driven gear 631.

[0058] On the other side of the crushing and feeding box 61, a third servo motor 64 for driving the active crushing roller 62 to rotate is provided. The output end of the third servo motor 64 can be fixedly connected to one end of the active crushing roller 62 away from the active transmission gear 621. When the third servo motor 64 drives the active crushing roller 62 to rotate clockwise, the active transmission gear 621 provided at the extended end of the active crushing roller 62 can drive the driven transmission crushing roller 63 to rotate counterclockwise through the driven gear 631, so that the active crushing roller 62 can cooperate with the driven transmission crushing roller 63 to crush the fish bones.

[0059] When this application is in operation, fish bones are placed inside the crushing and feeding box 61, and then the third servo motor 64 drives the active crushing roller 62 to rotate. When the third servo motor 64 drives the active crushing roller 62 to rotate clockwise, the active transmission gear 621 provided at the extended end of the active crushing roller 62 can drive the driven transmission crushing roller 63 to rotate counterclockwise through the driven gear 631, so that the active crushing roller 62 can cooperate with the driven transmission crushing roller 63 to crush the fish bones. The crushed fish bones descend along the inside of the crushing and feeding box 61 and enter the cylinder 2 through the feeding port 21. The fish bones that enter the cylinder 2 immediately fall to the bottom of the grinding disc 11. Then, when the first servo motor 18 drives the installation shaft 16 to rotate, the rotation of the installation shaft 16 drives the feeding mechanism 17 to rotate synchronously. While the feeding mechanism 17 rotates, it drives the feeding blades 171 to rotate synchronously. When the feeding blades 171 rotate, the bottom of the feeding blades 171 will stir the fish bone raw materials at the bottom of the grinding disc 11 upward, separating the fish bone raw materials from the grinding disc 11. At the same time, the feeding blades 171 stir the fish bone raw materials towards the side wall of the grinding disc 11, so that the fish bone raw materials can gather at a position close to the side wall inside the grinding disc 11. At the same time, the installation shaft 16 can also drive the fixed sleeve 131 fixed to its top to rotate synchronously. Then, the fixed sleeve 131 drives the vertical rod 132 to rotate around the central axis of the fixed sleeve 131 through the installation rod 1311 and the limiting rod 1312. While the vertical rod 132 rotates around the central axis of the fixed sleeve 131, the vertical rod 132 moves along the central axes of the installation rod 1311 and the limiting rod 1312 under the action of centrifugal force and approaches the side wall of the grinding disc 11, so that the vertical rod 132 drives the grinding roller 1323 at the bottom to cooperate with the side wall of the grinding disc 11 to grind the fish bone raw materials. When discharging, while the feeding blades 171 stir the fish bone raw materials upward, they can drive the fish bone raw materials that have been ground into powder to be suspended inside the cylinder 2. At the same time, the second servo motor 4 provided at the center of the top of the fairing 3 drives the rotating shaft 41 to rotate, and then the rotating shaft 41 drives the fan blades 5 to rotate synchronously. When the fan blades 5 rotate, the fan blades 5 can drive the fish bone raw materials ground into powder floating inside the cylinder 2 to move upward with the air and enter the inside of the fairing 3. When the powdered fish bone raw materials are sent into the inside of the fairing 3, the powdered fish bone raw materials can be smoothly discharged through the discharge port 31 provided on one side of the fairing 3. To ensure the stability of the rotating shaft 41. By fixing the limiting frame 32 inside the fairing 3, and then rotatably installing the rotating shaft 41 at the center of the limiting frame 32 and the central axis of the rotating shaft 41 longitudinally coincides with the central axis of the limiting frame 32. Effectively avoid the rotation axis 41 from shifting during rotation, thus ensuring the stability of the rotation axis 41.

[0060] The above embodiments merely represent one or several implementation manners of the present invention. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the appended claims.
