Description

Technical Field

[0001] The utility model relates to the technical field of meat grinders, and specifically relates to a meat grinder for evenly cutting and crushing frozen meat products. Background Art

[0002] A meat grinder is a device used by meat processing enterprises to process raw meat into granular meat fillings of different specifications according to different technological requirements. Before processing frozen meat products, they need to be slightly thawed and pre-processed into smaller frozen meat pieces than before, and then the meat grinder is used to cut and crush them.

[0003] During use, when the meat grinder is working, it is necessary to manually add frozen meat in a timely manner to ensure the working efficiency of the meat grinder during meat grinding. However, manually adding frozen meat into the interior of the meat grinder poses a certain risk of causing safety accidents.

[0004] To overcome the above defects, a prior art (Chinese patent with publication number CN220386757U and publication date January 26, 2024) provides a meat grinder. By setting the cooperation of a push plate and a cutting knife, starting the electric push rod can squeeze and cut large meat pieces inside the feeding port into smaller meat pieces, and then cooperate with a conveying screw and a cross-breaking knife to complete the crushing of the meat pieces, so as to facilitate the cutting of large frozen meat, thus facilitating the biting of the conveying screw and the frozen meat pieces, and effectively improving the crushing efficiency of large meat pieces.

[0005] The above mechanism adds frozen meat into the interior of the feeding port, and then uses the electric push rod to control the position of the push plate and achieve the uniform addition of frozen meat products. However, during actual use, the working time of the electric push rod still needs to be manually controlled, and simultaneously pushing in too much frozen meat at one time will also cause blockage at the feeding port of the device. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a meat grinder for evenly cutting and crushing frozen meat products to solve the problems raised in the above background art.

[0007] To achieve the above purpose, the utility model provides the following technical solution: A meat grinder for evenly cutting and crushing frozen meat products, including a meat grinder body. The top of the meat grinder body is fixedly connected with a control box, and a feeding pipe is arranged on one side of the control box. The middle position on one side of the meat grinder body is fixedly connected with a driving motor through a coupling, and the output end of the driving motor extends into the interior of the meat grinder body and is fixedly connected with a spiral feeding rod through bolts. One side of the spiral feeding rod is fixedly connected with a connecting rod, and a cutting knife is arranged on the outer side of the connecting rod. One side of the exterior of the meat grinder body is installed with a discharge port through bolts.

[0008] One end of the control box is rotatably connected to a cam, and a quantitative feeding mechanism for controlling the feeding amount is arranged inside the control box. The quantitative mechanism includes a partition plate, and the partition plate is rotatably connected inside the meat grinder body. One end of the partition plate extends to the outside of the meat grinder body and is connected to the cam, and one ends of the partition plate and the cam are both connected to the output end of the driving motor through belt pulleys;

[0009] Fixing rods are fixedly connected to the four corners at the bottom end of the meat grinder body, and a buffer and noise reduction mechanism for protecting the meat grinder body is arranged inside the fixing rods.

[0010] Furthermore, a pressing mechanism for pressing and preventing adhesion of frozen meat is arranged at the upper end inside the control box. The pressing mechanism includes a shielding plate, and the shielding plate is slidably connected inside the control box. A pressing rod is fixedly connected to the middle position at the bottom end of the shielding plate, and the bottom end of the pressing rod is arranged on one side between the partition plates.

[0011] Furthermore, a limiting rod is installed on one side of the shielding plate through bolts, and a limiting groove matching the limiting rod is opened on one side of the control box. A sliding structure is formed between the shielding plate and the control box through the limiting rod and the limiting groove.

[0012] Furthermore, the length of the cam is greater than the distance between the cam and the limiting rod, and the front view cross-section of the limiting rod is in an "L" shape.

[0013] Furthermore, the buffer and noise reduction mechanism includes fixing rods, and the fixing rods are fixedly connected to the four corners at the bottom end of the meat grinder body. A support rod is fixedly connected inside the fixing rod through a buffer spring, and the bottom end of the support rod passes through and extends to the outside of the fixing rod.

[0014] Furthermore, an anti-slip pad is fixedly connected to the bottom end of the support rod, and the anti-slip pads are evenly distributed at the bottom end of the support rod.

[0015] Furthermore, three groups of cutting knives are provided, and the cutting knives are distributed in a staggered manner:

[0016] 1. The output end of the driving motor rotates and drives the spiral feeding rod inside the meat grinder body to rotate, so that the driving motor drives the cam to rotate through the pulley. When the cam rotates, it pushes the upper limit rod to move the limit rod upward, and the limit groove drives the pressing rod and the shielding plate to move upward, and the frozen meat accumulated at the feeding pipe enters the interior of the control box through the fixed groove. Then, due to the change of the cam angle, the pressing rod and the shielding plate move downward and block the fixed groove to prevent too much frozen meat from entering the interior of the control box. The output end of the driving motor drives the partition plate to rotate through the pulley. The continuous rotation of the partition plate limits the amount of frozen meat that can fall into the partition plate each time, thereby realizing overall quantitative feeding, slowing down the feeding speed, and allowing the frozen meat to be continuously squeezed and crushed inside the meat grinder body, so that the frozen meat product can be cut and crushed more evenly;

[0017] Furthermore, the cam can be continuously rotated by the pulley at the output end of the driving motor. When the cam rotates to other angles, the limit rod loses the force of the cam and falls downward. The weight of the limit rod, the pressing rod and the shielding plate push the frozen meat, so that the frozen meat moves downward for a distance, so that the frozen meat will not be stuck in the fixed groove at the feed pipe and affect the closing and shielding of the shielding plate.

[0018] Furthermore, when the limit rod is pushed up and down, the cooperation between the limit groove and the limit rod can make the up and down movement of the pressing rod and the shielding plate more stable, effectively avoiding the situation where the pressing rod and the shielding plate are stuck when moving up and down;

[0019] 2. The buffer spring arranged at the bottom of the meat grinder body can dampen the vibration generated by the meat grinder body when it is working, so that the overall operation of the meat grinder body can be more stable. At the same time, the damper inside the buffer spring can reduce the shaking of the buffer spring, thereby increasing the stability of the device during shock absorption and buffering. The anti-slip pad at the bottom of the support rod can effectively avoid the problem of position displacement of the device during vibration;

[0020] Furthermore, by providing three groups of staggered cutting knives, the frozen meat can be continuously cut and crushed by cutting knives at different angles when entering one side of the meat grinder body, so that the frozen meat can be cut and crushed more evenly, effectively avoiding the situation of incomplete cutting.

Specific embodiments

[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0029] Embodiment 1:

[0030] As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 shown in the technical solution, in order to solve the problem that the meat grinder is blocked at the feeding place due to excessive addition of frozen meat products at one time: the meat grinder for evenly cutting and crushing the frozen meat products discloses a quantitative feeding mechanism, including a meat grinder body 1, a control box 2 is fixedly connected to the top of the meat grinder body 1, and a feed pipe 3 is arranged on one side of the control box 2. A drive motor 4 is fixedly connected to the middle position on one side of the meat grinder body 1 through a coupling, and the output end of the drive motor 4 extends into the meat grinder body 1 and is fixedly connected to a spiral feed rod 5 through bolts. A connecting rod 6 is fixedly connected to one side of the spiral feed rod 5, and a cutting knife 7 is arranged on the outer side of the connecting rod 6. A discharge port 8 is installed on one side of the outside of the meat grinder body 1 through bolts;

[0031] One end of the control box 2 is rotatably connected to a cam 12, and a quantitative feeding mechanism for controlling the feeding amount is arranged inside the control box 2. The quantitative feeding mechanism includes a partition plate 13, and the partition plate 13 is rotatably connected inside the meat grinder body 1. One end of the partition plate 13 extends to the outside of the meat grinder body 1 and is connected to the cam 12, and one ends of the partition plate 13 and the cam 12 are both connected to the output end of the driving motor 4 through pulleys. There are three groups of cutting knives 7, and the cutting knives 7 are distributed in a staggered manner.

[0032] In this example, frozen meat is added to the inside of the feeding pipe 3, and then the output end of the driving motor 4 rotates to drive the spiral feeding rod 5 inside the meat grinder body 1 to rotate, so that the driving motor 4 drives the cam 12 to rotate through a pulley. When the cam 12 rotates, it will push the upper limiting rod 14, causing the limiting rod 14 to move upward. At the same time, the limiting groove 15 drives the pressing rod 16 and the baffle plate 17 to move upward. The frozen meat accumulated at the feeding pipe 3 enters the inside of the control box 2 through the fixing groove. Then, due to the change in the angle of the cam 12, the pressing rod 16 and the baffle plate 17 move downward to block the fixing groove, preventing too much frozen meat from entering the inside of the control box 2. The output end of the driving motor 4 drives the partition plate 13 to rotate through a pulley. By continuously rotating the partition plate 13, the amount of frozen meat that can fall into the inside of the partition plate 13 each time is limited. When the partition plate 13 rotates to different angles, the frozen meat placed between the blades falls by gravity between the spiral feeding rods 5. The spiral feeding rod 5 continuously rotates to transport the frozen meat to the connecting rod 6 for crushing by the cutting knives 7. After the frozen meat is crushed, it is squeezed out of the inside of the meat grinder body 1 through the discharge port 8.

[0033] Embodiment Two:

[0034] Such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5The technical solution shown, based on Embodiment 1, aims to solve the problem that when adding frozen meat products, it is easy for the frozen meat to stick together and cannot be completely separated: For the meat grinder that evenly cuts and crushes the frozen meat products, a pressing mechanism is disclosed. At the upper end inside the control box 2, there is a pressing mechanism for pressing the frozen meat to prevent adhesion. The pressing mechanism includes a shielding plate 17, and the shielding plate 17 is slidably connected inside the control box 2. At the middle position of the bottom end of the shielding plate 17, a pressing rod 16 is fixedly connected, and the bottom end of the pressing rod 16 is arranged on one side between the partition plates 13. On one side of the shielding plate 17, a limiting rod 14 is installed through bolts, and a limiting groove 15 matching the limiting rod 14 is opened on one side of the control box 2. The shielding plate 17 and the control box 2 form a sliding structure through the limiting rod 14 and the limiting groove 15. The length of the cam 12 is greater than the distance between the cam 12 and the limiting rod 14, and the front cross-section of the limiting rod 14 is in an "L" shape.

[0035] In this example, the cam 12 can continuously rotate driven by the belt pulley at the output end of the driving motor 4. When the cam 12 rotates to other angles, the limiting rod 14 loses the pushing force of the cam 12 and drops downward. The weights of the limiting rod 14, the pressing rod 16, and the shielding plate 17 will push the frozen meat, causing the frozen meat to move downward by a certain distance, so that the frozen meat will not get stuck in the fixed groove at the feeding pipe 3 and affect the closing and shielding of the shielding plate 17.

[0036] Embodiment 3:

[0037] Such as Figure 1 、 Figure 2 、 Figure 3 and Figure 6 The technical solution shown aims to solve the problems that when the meat grinder is in use, it is easy for the device to shift its own position and generate relatively large noise due to the drive of the driving motor 4: For the meat grinder that evenly cuts and crushes the frozen meat products, a buffer and noise reduction mechanism is disclosed. At the four corners at the bottom end of the meat grinder body 1, fixed rods 9 are fixedly connected, and a buffer and noise reduction mechanism for protecting the meat grinder body 1 is arranged inside the fixed rods 9. The buffer and noise reduction mechanism includes the fixed rods 9, and the fixed rods 9 are fixedly connected to the four corners at the bottom end of the meat grinder body 1. Inside the fixed rods 9, a support rod 11 is fixedly connected through a buffer spring 10, and the bottom end of the support rod 11 passes through and extends outside the fixed rod 9. A non-slip pad 18 is fixedly connected to the bottom end of the support rod 11, and the non-slip pads 18 are equally spaced at the bottom end of the support rod 11.

[0038] In this example, the buffer spring 10 arranged at the bottom end of the meat grinder body 1 can dampen the vibration generated when the meat grinder body 1 is working, so that the overall operation of the meat grinder body 1 can be more stable. At the same time, the damper inside the buffer spring 10 can reduce the shaking of the buffer spring 10, thereby increasing the stability of the device during shock absorption and buffering, and the anti-slip pad 18 at the bottom end of the support rod 11 can effectively avoid the problem of position displacement of the device during vibration.

[0039] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
