Automatic skewering device for chicken skewers

Abstract

This application relates to the field of automatic skewering equipment technology, and discloses an automatic skewering device for chicken skewers to solve the problems of thinner parts of chicken being difficult to skewer and uneven distribution of chicken caused by the pushing of the skewers. By equidistantly arranged protrusions within a support mold, and a pressing block at the lower end of a pressing strip, with the protrusions and pressing blocks staggered, after the chicken is placed in the support mold, the output end of the pressing mechanism pushes the pressing strip and pressing block downwards, squeezing and fixing the chicken within the support mold. The chicken is squeezed into a wave shape by the protrusions and pressing blocks, ensuring that chicken on the center line of the support mold can be skewered regardless of its thickness, thus avoiding the problem of thin chicken at the center line being difficult to skewer. After the protrusions and pressing blocks fix the chicken, each protrusion and pressing block supports the chicken when the skewer contacts it, preventing the chicken within the support mold from being pushed to one end by the skewer, thus ensuring even distribution of chicken on the skewer.

Description

Technical Field

[0001] This application relates to the field of automatic skewering equipment, and more particularly to an automatic skewering equipment for chicken skewers. Background Technology

[0002] Chicken skewers typically refer to marinated chicken skewered on bamboo sticks and then grilled, pan-fried, or deep-fried. Automatic skewering equipment is a food processing device specifically designed to automatically or semi-automatically skewer meat, vegetables, fruits, and other ingredients onto bamboo or metal skewers. Its core value lies in significantly improving the efficiency of making skewers and similar products, while ensuring hygiene and uniform product specifications. The principles of automatic skewering equipment are generally similar, including steps such as placing ingredients, automatic skewer feeding, pushing the skewers, and conveying the finished products.

[0003] Automatic skewering equipment generally includes a support frame, a conveyor group, a support mold, a skewering group, a pressing mechanism, and a control system. When skewering chicken, the cut chicken is typically placed on the support mold. The conveyor group then holds the chicken directly below the pressing mechanism. After being skewered by the skewering group, the chicken is conveyed to the other end. However, because the thickness of the chicken is not uniform, if the chicken in the center of the support mold is thinner, this thinner section will be below the skewer when it is pierced, preventing it from being skewered. Furthermore, when the tip of the skewer contacts the chicken, it exerts a pushing force, pushing the chicken in the support mold to one end before it can be skewered. This results in uneven distribution of the chicken on the skewer, affecting the quality of the skewering process. Summary of the Invention

[0004] This application proposes an automatic skewering device for chicken skewers, which has the advantages of preventing thinner parts of the chicken from being difficult to skewer and preventing uneven distribution of chicken on the skewers, thereby solving the problems of thinner parts of the chicken being difficult to skewer and uneven distribution of chicken caused by the movement of the skewers.

[0005] To achieve the above objectives, this application adopts the following technical solution: an automatic skewer-making device for chicken skewers, comprising a support side frame, a conveyor group, and a control system. A conveyor chain is sleeved on the conveyor group, and several carrier molds are installed on the conveyor chain. A skewer-making group is installed on one side of the support side frame. A pressing mechanism is straddling the top of the support side frame. A pressing strip is fixedly installed on the output end of the pressing mechanism. Several protrusions are equidistantly installed inside the carrier mold. Several pressing blocks are equidistantly installed on the lower end face of the pressing strip. A skewer groove is opened at the middle position of the upper end face of the carrier mold, the upper end face of the protrusions, and the lower end face of the pressing blocks. The protrusions and pressing blocks are arranged alternately along the length direction of the carrier mold.

[0006] Furthermore, the distance between two adjacent protrusions is the same as the distance between two adjacent pressing blocks.

[0007] Furthermore, meat strip baskets are fixedly installed on both sides of the supporting side frame.

[0008] Furthermore, when the output end of the pressing mechanism pushes the pressing block into the bearing mold, the axis of the protrusion and the bamboo skewer groove on the pressing block is at the middle position in the depth direction of the bearing mold.

[0009] Furthermore, two retaining strips are fixedly installed on both sides of the bottom end of the pressing mechanism, with the bottom end of the retaining strips close to the upper surface of the bearing mold.

[0010] Furthermore, a movable groove is provided on the bearing mold at the bottom of the protrusion, and an elastic element is provided in the movable groove; the protrusion includes a fixed block and a movable block, and a bamboo skewer groove is provided in the middle of the upper end face of the fixed block and the movable block. The bottom end of the movable block passes through the fixed block and rests on the upper end face of the elastic element; a square stop groove is provided in the middle of the fixed block, and a limiting ring is fixedly sleeved on the outer side of the movable block. The limiting ring is slidably installed in the stop groove; a stepped extrusion groove is provided on the opposite side wall of the fixed block. An elastic block is fixedly installed on the step of the extrusion groove near the center of the fixed block. An extrusion block is slidably installed in the extrusion groove. The extrusion block is U-shaped. The inner wall of one side support arm of the extrusion block is fixedly connected to the elastic block, and the outer wall of the other side of the extrusion block is flush with the outer wall of the fixed block.

[0011] Furthermore, the elastic element is a support element that always has a supporting elastic force.

[0012] Furthermore, the limiting ring is a frustum shape, and the sidewall of the limiting ring is in contact with the sidewall of the extrusion block.

[0013] Furthermore, two auxiliary strips are inserted into the movable block, and the two auxiliary strips are respectively located on both sides of the bamboo skewer groove. The bottom end of the auxiliary strip passes through the movable block and the limiting ring. The two sides of the bottom end of the auxiliary strip are in close contact with the extrusion block, and the top end of the auxiliary strip protrudes from the upper surface of the movable block.

[0014] This application has the following beneficial effects:

[0015] 1. The automatic skewering device for chicken skewers provided in this application has protrusions evenly spaced inside the support mold and a pressing block at the lower end of the pressing strip. The protrusions and pressing blocks are arranged alternately. After the chicken is placed inside the support mold, the output end of the pressing mechanism pushes the pressing strip and pressing block down to squeeze and fix the chicken inside the support mold. At this time, the chicken is squeezed into a wave shape by the protrusions and pressing blocks. Regardless of the thickness of the chicken, the chicken on the center line of the support mold can be pierced by bamboo skewers, thereby avoiding the chicken on the center line being too thin and difficult to be pierced by bamboo skewers.

[0016] 2. The automatic skewering device for chicken skewers provided in this application, after the protrusions and pressing blocks fix the chicken, when the bamboo skewer contacts the chicken, each protrusion and pressing block supports the chicken, thereby preventing the chicken in the support mold from being pushed to one end by the bamboo skewer, so that the chicken on the bamboo skewer can be evenly distributed.

[0017] 3. The automatic skewering device for chicken skewers provided in this application, when the pressing bar and pressing block are pushed down by the output end of the pressing mechanism, the pressing bar first squeezes the moving block, and the moving block squeezes the elastic element at the bottom, causing the moving block to move down. The moving block drives the limiting ring to move synchronously, so that the limiting ring squeezes and pushes the pressing block, thereby causing the pressing block to extend to both sides, so that the chicken around the bamboo skewer groove is pushed on the pressing block. When the bamboo skewer passes through the chicken here, it prevents the chicken from moving between the protrusion and the pressing block, which would make it difficult to pass through.

[0018] 4. The automatic skewering device for chicken skewers provided in this application, after the skewered chicken skewers are removed from the bottom of the pressing mechanism, the elastic element pushes the moving block upward under its own elastic force, so that the moving block separates the chicken skewers that are attached to the bottom of the support mold from the support mold. Furthermore, under the elastic force of the elastic block, the extrusion block is pushed back to its original position, so that the extrusion block pushes the auxiliary strip upward. The upward-moving auxiliary strip pushes the chicken skewers that are attached to the moving block off, thereby preventing the chicken skewers from sticking to the support mold and making it difficult to automatically fall off and collect from the end of the conveyor chain.

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0031] Example 1

[0032] Please see Figures 1-8 An automatic skewering device for chicken skewers includes a support side frame 1, a conveyor group 2, a conveyor chain 21, a bearing mold 3, a skewering group 4, a pressing mechanism 5, a pressing strip 51, and a control system 6. The conveyor group 2 is located between two support side frames 1. Two parallel conveyor chains 21 are mounted on the conveyor group 2. When the conveyor group 2 is running, the conveyor chains 21 are driven by the conveyor group 2. Several bearing molds 3 are equidistantly installed on the two conveyor chains 21. The length direction of the bearing molds 3 is perpendicular to the support side frame 1. The skewering group 4 is fixedly installed on one side of the support side frame 1. The pressing mechanism 5 spans the top of the support side frame 1. A pressing strip 51 is fixedly installed on the output end of the pressing mechanism 5. The pressing strip 51 and the axis of the skewering group 4 are on the same vertical plane. Meat strip baskets 11 are fixedly installed on both sides of the support side frame 1. The meat strip baskets 11 are used to place cut chicken. The control system 6 is fixedly installed on one side of the support side frame 1. The control system 6 is used to control the operation of the automatic skewering device.

[0033] Several protrusions 31 are installed at equal intervals inside the bearing mold 3, and several pressing blocks 52 are installed at equal intervals on the lower end face of the pressing strip 51. Bamboo skewer grooves 32 are opened in the middle position of the upper end face of the bearing mold 3, the upper end face of the protrusions 31 and the lower end face of the pressing blocks 52. The protrusions 31 and pressing blocks 52 are arranged alternately in the length direction of the bearing mold 3, and the distance between two adjacent protrusions 31 is the same as the distance between two adjacent pressing blocks 52.

[0034] When using the automatic skewering device to skewer chicken, the chicken is first evenly placed in the support mold 3. The conveyor group 2 drives the conveyor chain 21 and the support mold 3 to move, transferring the support mold 3 containing the chicken to directly below the pressing mechanism 5. At this time, the control system 6 starts the pressing mechanism 5. The output end of the pressing mechanism 5 drives the pressing strip 51 and the pressing block 52 to move down until the pressing block 52 is pushed into the support mold 3. The protrusion 31 in the support mold 3 and the pressing block 52 at the lower end of the pressing strip 51 are staggered, squeezing and fixing the chicken, and the chicken is wavy in shape. Then, the control system 6 starts the skewering group 4. The skewer assembly 4 passes the bamboo skewer through the bamboo skewer groove 32 between the support mold 3, the protrusion 31, and the pressing block 52. Regardless of the thickness of the chicken, since the chicken is generally wavy, the chicken on the center line of the support mold 3 can be pierced by the bamboo skewer, thus avoiding the chicken on the center line being too thin and difficult to pierce by the bamboo skewer. Furthermore, after the protrusion 31 and the pressing block 52 squeeze and fix the chicken, when skewering, the bamboo skewer squeezes the chicken, and each protrusion 31 and pressing block 52 supports the chicken, thus preventing the chicken in the support mold 3 from being pushed to one end by the bamboo skewer, so that the chicken on the bamboo skewer can be evenly distributed.

[0035] It should be further explained that when the pressing block 52 is pushed into the bearing mold 3 at the output end of the pressing mechanism 5, the axis of the bamboo skewer groove 32 on the protrusion 31 and the pressing block 52 is in the middle position in the depth direction of the bearing mold 3. When the bamboo skewer passes through the bamboo skewer groove 32, it ensures that the bamboo skewer can pass through the middle position between each peak and trough of the chicken, and prevents the bamboo skewer from shifting.

[0036] In addition, two sides of the bottom end of the pressing mechanism 5 are fixedly installed with skewer-blocking strips 53, and the bottom end of the skewer-blocking strips 53 is close to the upper end face of the support mold 3. When the bamboo skewers are pushed into the bamboo skewer groove 32 of the support mold 3 by the skewer-skewering group 4, the skewer-blocking strips 53 press against both ends of the bamboo skewers. When the pressing strips 51 and pressing blocks 52 are reset with the output end of the pressing mechanism 5, the skewered chicken skewers are prevented from moving with the pressing strips 51 and pressing blocks 52.

[0037] Example 2

[0038] Example 2 is a further improvement based on Example 1.

[0039] Unlike Example 1, please refer to Figures 1-8 A movable groove 33 is provided on the bearing mold 3 at the bottom end of the protrusion 31. An elastic element 331 is provided in the movable groove 33. The elastic element 331 is a support element that always has a supporting elastic force. The elastic element 331 can be a compression elastic force, a compression elastic rubber block, etc. The protrusion 31 includes a fixed block 311 and a movable block 312. A bamboo skewer groove 32 is provided in the middle of the upper end face of the fixed block 311 and the movable block 312. The upper end face of the movable block 312 protrudes from the upper end face of the bearing mold 3. The bottom end of the movable block 312 passes through the fixed block 311 and abuts against the upper end face of the elastic element 331. The middle of the fixed block 311 is opened A square retaining groove 313 is provided. A limiting ring 314 is fixedly sleeved on the outer side of the lower position of the moving block 312. The limiting ring 314 is slidably installed in the retaining groove 313. A stepped extrusion groove 315 is opened on the opposite side wall of the fixed block 311. An elastic block 316 is fixedly installed on the step of the extrusion groove 315 near the center of the fixed block 311. An extrusion block 317 is slidably installed in the extrusion groove 315. The extrusion block 317 is U-shaped. The inner wall of one side support arm of the extrusion block 317 is fixedly connected to the elastic block 316. The outer wall of the other side of the extrusion block 317 is flush with the outer wall of the fixed block 311.

[0040] It should be noted that the limiting ring 314 is a frustum shape, and the side wall of the limiting ring 314 fits against the side wall of the extrusion block 317; when the limiting ring 314 moves down with the moving block 312, the edge of the limiting ring 314 can push the extrusion block 317 to move.

[0041] When a bamboo skewer pierces chicken, the skewer and chicken must press against each other to pass through. If the skewer contacts the edge of the chicken, even slight movement of the chicken can prevent the skewer from passing through. Therefore, the protrusion 31 is divided into a fixed block 311 and a movable block 312. During use, the output end of the pressing mechanism 5 pushes the pressing bar 51 and the pressing block 52 downwards. The downward-moving pressing bar 51 first presses against the movable block 312, which in turn presses against the elastic element 331 at the bottom, causing the movable block 312 to move downwards. The moving block 312 moves downward, causing the limiting ring 314 to move synchronously, so that the side wall of the limiting ring 314 squeezes and pushes the squeezing block 317, thereby squeezing the elastic block 316. The squeezing block 317 extends outward, and the extended squeezing block 317 squeezes the chicken around the bamboo skewer groove 32, so that the chicken is pressed against the pressing block 52, thereby fixing the chicken around the bamboo skewer groove 32. When the bamboo skewer passes through the chicken here, it prevents the chicken from moving between the protrusion 31 and the pressing block 52, making it difficult to pass through.

[0042] In addition, two auxiliary strips 34 are inserted on the movable block 312, and the two auxiliary strips 34 are respectively located on both sides of the bamboo skewer groove 32. The bottom end of the auxiliary strip 34 passes through the movable block 312 and the limiting ring 314. The two sides of the bottom end of the auxiliary strip 34 are in close contact with the pressing block 317, and the top end of the auxiliary strip 34 protrudes from the upper surface of the movable block 312.

[0043] When the pressing strip 51 and pressing block 52 are pushed down at the output end of the pressing mechanism 5, the pressing strip 51 first contacts the auxiliary strip 34 on the moving block 312. Since the moving block 312 is supported by the elastic element 331 (the elastic coefficient of the elastic element 331 is greater than the elastic coefficient of the elastic block 316), the pressing strip 51 squeezes the auxiliary strip 34, causing the auxiliary strip 34 to move downward. The bottom end of the downward-moving auxiliary strip 34 pushes the pressing block 317, causing the pressing block 317 to squeeze a small part of the elastic block 316, thereby causing the pressing block 317 to extend a small part. The extended part of the pressing block 317 pre-fixes the chicken around the bamboo skewer groove 32, preventing the pressing strip 51 and pressing block 52 from moving the chicken too much when they move down, which would affect the subsequent skewering.

[0044] Furthermore, after skewering, when the conveyor group 2 drives the conveyor chain 21 and the support mold 3 away from the lower end of the pressing mechanism 5, the moving block 312 moves upward and resets under the push of the elastic force of the elastic element 331. The upward moving block 312 pushes the skewered chicken to move synchronously, so that the chicken skewers adhering to the bottom end of the support mold 3 are separated. In addition, during the reset process of the moving block 312, the supporting elastic force of the elastic block 316 pushes the pressing block 317 to move and reset. During the reset process of the pressing block 317, it pushes the bottom ends on both sides of the auxiliary strip 34, so that the auxiliary strip 34 moves upward. The upward moving auxiliary strip 34 will separate from the chicken skewers adhering to the upper surface of the moving block 312, thereby preventing the chicken skewers from adhering to the support mold 3, which would make it difficult for the chicken skewers to fall off automatically when they reach the end of the conveyor chain 21.

[0045] The working principle of this invention is as follows:

[0046] Please see Figures 1-8When using an automatic skewering device to skewer chicken, the chicken is first evenly placed in the support mold 3. The conveyor group 2 drives the conveyor chain 21 and the support mold 3 to move, and the support mold 3 containing the chicken is transferred to the underside of the pressing mechanism 5. At this time, the control system 6 starts the pressing mechanism 5. The output end of the pressing mechanism 5 drives the pressing strip 51 and the pressing block 52 to move down until the pressing block 52 is pushed into the support mold 3. The protrusion 31 in the support mold 3 and the pressing block 52 at the lower end of the pressing strip 51 are staggered to squeeze and fix the chicken, and the chicken is wavy in shape. Then, the control system 6 starts the skewering group 4. The skewering group 4 passes the bamboo skewer through the bamboo skewer groove 32 between the support mold 3, the protrusion 31 and the pressing block 52. Regardless of the thickness of the chicken, since the chicken is wavy in shape, the chicken on the center line of the support mold 3 can be skewered, thus avoiding the chicken on the center line being too thin and difficult to be skewered.

[0047] Furthermore, after the protrusions 31 and pressing blocks 52 compress and fix the chicken, when the chicken is skewered, the bamboo skewers compress the chicken, and each protrusion 31 and pressing block 52 supports the chicken, thereby preventing the chicken in the bearing mold 3 from being pushed to one end by the bamboo skewers, so that the chicken on the bamboo skewers can be evenly distributed.

[0048] When the pressing strip 51 and pressing block 52 are pushed down at the output end of the pressing mechanism 5, the pressing strip 51 first contacts the auxiliary strip 34 on the moving block 312. Since the moving block 312 is supported by the elastic element 331, the pressing strip 51 squeezes the auxiliary strip 34, causing the auxiliary strip 34 to move downward. The bottom end of the downward-moving auxiliary strip 34 pushes the pressing block 317, causing the pressing block 317 to squeeze a small part of the elastic block 316, thereby causing the pressing block 317 to extend a small part. The extended part of the pressing block 317 pre-fixes the chicken around the bamboo skewer groove 32, preventing the pressing strip 51 and pressing block 52 from moving the chicken too much when they move down, which would affect the subsequent skewering.

[0049] Then, the pressing strip 51 and the pressing block 52 continue to move downward. The pressing strip 51 first squeezes the moving block 312, and the moving block 312 squeezes the elastic element 331 at the bottom, thereby causing the moving block 312 to move downward. The moving block 312 drives the limiting ring 314 to move synchronously, so that the side wall of the limiting ring 314 squeezes and pushes the pressing block 317, thereby causing the pressing block 317 to continue to squeeze the elastic block 316. The pressing block 317 continues to extend, and the extended pressing block 317 further squeezes the chicken around the bamboo skewer groove 32, so that the chicken is pushed against the pressing block 52, thereby fixing the chicken around the bamboo skewer groove 32. When the bamboo skewer passes through the chicken here, it prevents the chicken from moving between the protrusion 31 and the pressing block 52, making it difficult to pass through.

[0050] Furthermore, after skewering, when the conveyor group 2 drives the conveyor chain 21 and the support mold 3 away from the lower end of the pressing mechanism 5, the moving block 312 moves upward and resets under the push of the elastic force of the elastic element 331. The upward moving block 312 pushes the skewered chicken to move synchronously, so that the chicken skewers adhering to the bottom end of the support mold 3 are separated. In addition, during the reset process of the moving block 312, the supporting elastic force of the elastic block 316 pushes the pressing block 317 to move and reset. During the reset process of the pressing block 317, it pushes the bottom ends on both sides of the auxiliary strip 34, so that the auxiliary strip 34 moves upward. The upward moving auxiliary strip 34 will separate from the chicken skewers adhering to the upper surface of the moving block 312, thereby preventing the chicken skewers from adhering to the support mold 3, which would make it difficult for the chicken skewers to fall off automatically when they reach the end of the conveyor chain 21.

[0051] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of the invention.
