[0049] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that the directional terms such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the present invention are only based on the accompanying drawings of the present invention, and are not specific limitations of the present invention.

[0050] Embodiment 1

[0051] like Figure 1 As shown, a food threading device of the present invention comprises a frame 1, a conveying mechanism 2 arranged on the frame 1, a fixing mechanism 3 arranged on the conveying mechanism 2, a drilling mechanism 4 for drilling holes in food, and a needle threading mechanism 5 for threading a needle through food, wherein the food is located inside the fixing mechanism 3;

[0052] The drilling mechanism 4 and the needle threading mechanism 5 are arranged in sequence along the conveying mechanism 2; or,

[0053] The drilling mechanism 4 and the needle threading mechanism 5 are respectively located at two ends of the fixing mechanism 2;

[0054] The fixing mechanism 3 with food fixed inside moves on the conveying mechanism 2, the drilling mechanism 4 drills holes in the food moved to a preset position, and then the needle-piercing mechanism 5 pierces the food.

[0055] The frame 1 is used for fixing the conveying mechanism 2, the fixing mechanism 3, the drilling mechanism 4 and the needle threading mechanism 5, so as to facilitate the drilling and needle threading of the food inside the fixing mechanism 3 in sequence, thereby realizing automatic stringing and improving production efficiency.

[0056] like Figure 2-3 As shown, the conveying mechanism 2 is used to convey food, so that the food can perform different actions at different workstations, thereby realizing the process of automatic stringing. It includes a mounting table 21 for mounting the fixing mechanism, a driving wheel 22 for driving the fixing mechanism 3 to move, and a conveying motor 23 for driving the driving wheel 22 to rotate. The mounting table 21 is fixed on the frame 1, and a conveying track 24 is provided thereon. The fixing mechanism 3 is embedded in the conveying track 24. The conveying track 24 is in a ring shape, a strip shape, or other regular or irregular shapes on the mounting table 21, and is specifically set according to actual needs. In this embodiment, the conveying track 21 is in a ring shape, which is convenient for setting different workstations around the mounting table 21, thereby realizing the assembly line operation of food processing and saving production space.

[0057] like Figure 4 As shown, the driving wheel 22 is used to drive the fixing mechanism to move, which is arranged at both ends of the installation table, including a driving body 221 and a plurality of driving holes 222 arranged on the edge of the driving body 221. The number of the driving holes 222 is several, which are evenly distributed on the circumference of the driving body 221 and have an arc-shaped structure. The curvature of the front end of the driving hole 222 is smaller than the curvature of the rear end thereof, so that the fixing mechanism 3 can enter the driving hole 222 through the front end of the driving hole 222, and drive the fixing mechanism 3 to move through the rear end of the driving hole 222, thereby ensuring that the driving wheel 22 can smoothly drive the fixing mechanism 3 to move.

[0058] It should be noted here that since there are several fixing mechanisms 3, assuming that fixing mechanism n is located in the current driving hole, the front end of the driving hole is located between fixing mechanism n-1 and fixing mechanism n, and the rear end of the driving hole is located between fixing mechanism n and fixing mechanism n+1.

[0059] The transmission motor 2 is connected to the driving wheel 22, which drives the driving wheel 22 to rotate. Therefore, during the rotation of the driving wheel, the side wall of the driving hole 222 first enters between the adjacent fixing mechanisms 3, and its rear end abuts against the fixing mechanism 3. Since the driving wheel 22 is rotating, the fixing mechanism 3 located inside the driving hole 222 is squeezed by the rear end of the driving hole 222 and moves along the direction of rotation of the driving wheel 22. In this way, the movement of the fixing mechanism 3 can be realized, and the automatic transmission of food is realized. The conversion between different workstations during the food processing process can be achieved by water flow, thereby improving production efficiency. In this embodiment, the transmission motor is connected to the driving wheel.

[0060] like Figure 5 As shown, the fixing mechanism 3 is embedded in the conveying track of the conveying mechanism 2, and is used to fix the food, so that the drilling mechanism 4 and the needle-threading mechanism 5 can process the food accordingly. Specifically, the fixing mechanism 3 includes a base 31, a first clamp 32 connected to the base 31, a second clamp 33 cooperating with the first clamp 32, and a conveying slide 34 arranged on the base 31. A accommodating space is formed between the first clamp 32 and the second clamp 33 for accommodating food. In order to facilitate the placement of food, the first clamp 32 and the second clamp 33 are rotatably connected to the base 31, and are used to change the size of the accommodating space according to actual needs, so as to realize the loosening or clamping of the food, facilitate the placement, removal or clamping of the food, and ensure the smooth progress of the needle-threading process.

[0061] Specifically, a rotating shaft may be provided on the base 31 , and guide holes may be provided on the first clamp 32 and the second clamp 33 , and a rotatable connection may be achieved by extending the rotating shaft into the guide holes.

[0062] As another embodiment of the present invention, the first clamp 32 is slidably connected to the base 31 to change the size of the accommodating space. The specific slidable connection method is a conventional technical means in the field and will not be repeated here.

[0063] The conveying slider 34 is located at the bottom of the base 31 and is embedded in the conveying track 24 so as to move along the conveying track 24 under the action of the driving wheel 22 to realize the conveying of the fixing mechanism 3 and the food.

[0064] In order to prevent the conveying slider 34 from escaping from the conveying track 24 and affecting the conveying of food, limiting grooves 35 are provided on both sides of the conveying slider 34. Correspondingly, limiting protrusions 25 are provided on both sides of the conveying track 24. The limiting protrusions 25 match the shape, size and position of the limiting grooves 35, and the limiting protrusions 25 are embedded in the limiting grooves 35, thereby realizing the limitation of the conveying slider 34, preventing the slider from escaping, and ensuring the normal movement of the fixing mechanism 3.

[0065] In order to expose the food inside the fixing mechanism 3 and facilitate the drilling mechanism 4 and the needle threading mechanism 5 to respectively operate on the food, through holes are provided on the top and / or bottom of the fixing mechanism 3, and the drilling mechanism 4 and the needle threading mechanism 5 operate on the food through the through holes.

[0066] like Figure 1-2 As shown, in order to smoothly open and close the first clamp 32 and the second clamp 33 to facilitate the placement of food, a guide rod 6 is also included. The guide rod 6 is integrally formed and includes an opening section 61, a guide section 62, a closing section 63 and a straightening section 64 arranged in sequence. The opening section 61 extends from the top of the mounting table 21 to the fixing mechanism 3, so that the first clamp 32 can be opened from the base 31. The guide section 62 is arranged parallel to the mounting table 21 to ensure that the fixing mechanism 3 is always in an open state or a closed state. The closing section 63 extends from the mounting table 21 to the fixing mechanism 3. One side of the fixing mechanism 3 extends to the mounting table 21, and is used to close the first clamp 32 from the base 31. After the food is placed, the fixing mechanism 3 is closed by the closing section 63, thereby fixing the food. The straightening section 64 extends and bends from the mounting table 21 in a direction close to the conveying track 24, and is used to guide the first clamp 32 and the second clamp 33 to rotate, so that the first clamp 32 and the second clamp 33 are rotated from a horizontal state to a vertical state, which is convenient for drilling and threading. It is located at the front end of the drilling mechanism 4.

[0067] In order to prevent the opening direction of the first clamp 32 in the fixing mechanism 3 from being a non-preset direction, thereby affecting the opening and closing of the fixing mechanism and the normal operation of the fixing mechanism, a guide plate 7 is also included, and the guide plate 7 is perpendicular to the opening direction of the first clamp 32.

[0068] like Figure 6-7As shown, the drilling mechanism 4 is used to drill holes in food, and includes a mounting frame 41 arranged on the frame 1, a sliding frame 42 arranged on the mounting frame 41, a sliding plate 43 slidably connected to the sliding frame 42, and a drilling structure 44 fixed on the sliding plate 43. The mounting frame 41 is arranged on the frame 1, and is used to install the sliding frame 42 and the drilling structure 44, and is used to lift the sliding frame 42 and the drilling structure 44 to facilitate drilling of food in the fixing mechanism 3, thereby ensuring the smooth progress of the drilling process.

[0069] The sliding frame 42 is arranged on the mounting frame 41 , so that the sliding plate 43 can move on the sliding frame 42 , thereby realizing the movement of the drilling structure 44 , and realizing the drilling and withdrawal of the drilling structure 44 .

[0070] like Figure 7 As shown, the drilling structure 44 is fixed on the sliding plate 43, and includes a drill bit 441 and a drill bit mounting plate 442 for mounting the drill bit 441, and the drill bit mounting plate 442 is fixed on the sliding plate 43. When working, the drill bit 441 rotates by itself, and the sliding plate 43 moves along the sliding frame 42 toward the fixing mechanism 3, and the drill bit slowly extends into the food and leaves a hole on the food, until the drilling is completed and the drill bit 441 withdraws to complete the drilling of the food.

[0071] like Figure 7-8 As shown, generally, food is skewered at the center position, so the drilling needs to be drilled at the center position of the food. In order to facilitate positioning and realize accurate drilling of food, a limiting mechanism 8 is also included. The limiting mechanism 8 includes a limiting frame 81, a limiting motor 82 that drives the limiting frame 81 to move up and down, a guide hole 83 provided on the limiting frame 81, and a guide groove 84 provided on the limiting frame 81. The guide hole 83 is located at the center position of the guide groove 84. The limiting motor 82 drives the limiting frame 81 to move close to or away from the fixing mechanism 3. The guide hole 83 is a through hole that passes through the limiting frame 81. The drill bit 441 passes through the guide hole 83 to process the food below it. The guide groove 84 is arranged facing the fixing mechanism 3, and its shape and size match the shape and size of the top of the fixing mechanism 3. That is, during the working process, the limiting motor 82 drives the limiting frame 81 to move in the direction close to the fixing mechanism 3, so that the top of the fixing mechanism 3 extends into the guide groove 84, and the drill bit starts drilling.

[0072] It should be noted here that, by setting the guide hole 83 and the guide groove 84, the drill bit 441 is always aligned with the center position of the fixing mechanism 3 to process the food inside the fixing mechanism 3, thereby ensuring the accuracy of the position of the food drilling hole.

[0073] like Figure 9-11 As shown, the needle threading mechanism 5 is used to thread the food, and includes a needle holder 51, a needle storage structure 52, a pushing structure 53 located on one side of the needle storage structure 52, a rotating structure 54 for driving the needle holder 51 to rotate, and a lifting structure 55 located below the fixing mechanism 3. The needle storage structure 52 is used to temporarily store the needles and output the needles according to actual needs. In this embodiment, one needle is output each time. Specifically, the needle storage structure 52 includes a needle storage box 521 and a roller 522 located on one side of the needle storage box 521, wherein the needle is located inside the needle storage box 521, the bottom of the needle storage box 521 is a V-shaped structure, and an opening 523 is provided on one side thereof, so that the roller 522 contacts the needle inside it through the opening 523 to achieve the output of the needle, and accordingly, the surface of the roller 522 is provided with grooves 524 arranged at intervals, and the grooves 524 are distributed in the entire radial direction of the roller 522, and the grooves 524 are parallel to the needle, and a gap is provided between the roller 522 and the needle storage box 521, and the width of the gap is smaller than the diameter of the needle, so only one needle is allowed to pass at a time, so when working, when the roller 522 rolls, the needle inside the needle storage box 521 is embedded in the groove 524 and rotates with the groove 524, so that the needle is brought out of the needle storage box 521.

[0074] like Fig.12 As shown, the pushing structure 53 is located at one side of the needle storage structure 52, and is used to push the needle into the lifting structure 55, so that the lifting structure 55 can insert the needle into the food. It includes a pushing cylinder 531 and a pushing needle holder 532 located at one end of the pushing cylinder 531. The pushing cylinder 531 is fixed on the frame and is used to drive the pushing needle holder 532 to move back and forth to push the needle. The pushing needle holder 532 is located at the end of the pushing cylinder 531, and its position matches the position of the needle outside the needle storage box 521, so as to align the needle inside the groove 524 to push the needle.

[0075] like Fig.10 As shown, the lifting structure 55 is used to realize the lifting and lowering of the needle holder 51, which is convenient for needle loading and threading. It includes a lifting cylinder 551 and a lifting plate 552 arranged on the top of the lifting cylinder 551. The lifting cylinder 551 drives the lifting plate 552 to rise and fall, and the lifting plate 552 is used to install the needle holder 51 and the rotating structure 54.

[0076] The needle holder 51 is used to place the needle, and a mounting hole is provided inside the needle holder for accommodating the needle. The position of the needle holder 51 matches the position of the needle push holder 532, that is, the needle holder is located at one end of the needle, and the needle push holder 532 is located at the other end of the needle, ensuring that the needle push holder 532 can smoothly send the needle into the mounting hole to fix the needle.

[0077] The rotating structure 54 is used to drive the needle holder to rotate. Here, since the fixing mechanism 3 is located at the top of the needle holder 51 and the needle is located at one side of the needle holder 51, after the needle is installed on the needle holder 51, the rotating structure 54 is used to drive the needle holder to rotate 90°, and then the lifting cylinder 551 drives the lifting plate 552, the needle holder 51 and the needle to rise together, so that the needle is inserted into the food in the fixing mechanism 3, thereby realizing the needle threading function. In this embodiment, the rotating structure is a rotating motor.

[0078] The food threading device provided in this embodiment, when working, the food is fixed by the fixing mechanism 3 and moves along the conveying track 24 under the action of the conveying mechanism 2. When it moves to the bottom of the drilling mechanism 4, the drill bit 441 follows the sliding plate 43 and moves downward along the sliding frame 42, and rotates itself until it penetrates into the preset position in the food. The drill bit 441 stops rotating, the drill bit 441 and the sliding plate 43 are reset, and the needle threading mechanism 5 starts to thread the needle. At this time, the needle inside the needle storage box 521 is output outside the needle storage box 521 under the action of the roller 522, and the pushing structure 53 pushes the needle into the needle holder 51. The rotating structure 54 drives the needle holder 51 to rotate so that the needle is facing the food, and the lifting structure 55 drives the needle and the needle holder to rise until they are inserted into the food.

[0079] Embodiment 2

[0080] In the first embodiment, the drilling mechanism 4 and the needle threading mechanism 5 are respectively located at the two ends of the fixing mechanism 3. After the drilling is completed, the needle threading is performed, that is, the device cannot perform the drilling and needle threading work at the same time, and the work efficiency is relatively low. Based on this, the present invention also provides a better solution, such as Figure 13-15 As shown, the drilling mechanism 4 and the needle threading mechanism 5 are arranged in sequence along the conveying mechanism 2.

[0081] The needle threading mechanism of this embodiment has basically the same structure as the above-mentioned needle threading mechanism, except that corresponding adjustments need to be made according to the position change. Therefore, the difference between the needle threading mechanism in this embodiment and the above-mentioned structure is that the needle threading mechanism in this embodiment does not have a lifting structure, but replaces the lifting structure with a downward pressing structure.

[0082] Specifically, Figure 13-14 As shown, the needle threading mechanism 5 includes a needle holder 51, a needle storage structure 52, a pushing structure 53 located on one side of the needle storage structure 52, a rotating structure 54 for driving the needle holder to rotate, and a pressing structure 56 located above the fixing mechanism 3;

[0083] The pressing structure 56 is used to press the needle in the needle holder 51 into the food, and includes a pressing sliding frame 561, a pressing sliding plate 562 connected to the pressing sliding frame 561, and a pressing plate 563 connected to the pressing sliding plate 562. The pressing sliding frame 561 is fixed to the frame 1, and the pressing sliding plate 562 moves up and down along the pressing sliding frame 561. The pressing plate 563 is located above the needle and abuts against the end of the needle. During its descent, the pressing plate 563 presses the needle so that the needle is inserted into the food, thereby achieving the needle threading work.

[0084] There are many ways for the pressing sliding plate 562 to move along the pressing sliding frame 561. For example, a driving structure such as a cylinder, a screw rod, a motor, etc. can be used to drive the pressing sliding plate to move. Other methods can also be used, which will not be described in detail here.

[0085] In order to prevent the needle in the needle holder 51 from sliding down and affecting the smooth needle threading process, an elastic glue is further provided in the needle holder 51. The elastic glue is made of rubber or silicone and is used to increase the friction between the needle holder and the needle to prevent the needle from sliding down under the action of gravity.

[0086] The food threading device provided by the present invention is configured such that when the food is in operation, the food is fixed by the fixing mechanism 3 and moves along the conveying track 24 under the action of the conveying mechanism 2. When the food moves to the bottom of the drilling mechanism 4, the drill bit 441 follows the sliding plate 43 and moves downward along the sliding frame 42, and rotates itself until it penetrates into the preset position in the food. Then the drill bit 441 stops rotating, the drill bit 441 and the sliding plate 43 are reset, the fixing mechanism 3 and the food continue to move to the bottom of the needle threading mechanism 5, and the needle threading mechanism 5 starts to thread the needle. At this time, the needle inside the needle storage box 521 is output outside the needle storage box 521 under the action of the roller 522, the pushing structure 53 pushes the needle into the needle holder 51, the rotating structure 54 drives the needle holder 51 to rotate so that the needle faces the food, and the pressing structure 56 drives the needle and the needle holder 51 to descend until they are inserted into the food.

[0087] The food stringing device provided by the present invention realizes mechanized online stringing of food through the arrangement of the conveying mechanism 2, the fixing mechanism 3, the drilling mechanism 4 and the threading mechanism 5, has high production efficiency, does not require a large amount of labor, and saves labor costs.

[0088] The above is a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
