Abstract
Description
Technical Field
[0001] This utility model belongs to the field of food processing technology, and in particular relates to a positioning and skewering structure for skewering pork tenderloin. Background Technology
[0002] The pork tenderloin skewer machine is a piece of equipment for meat processing, suitable for barbecue restaurants and pre-made vegetable factories. It can automatically skewer pork tenderloin, adapt to bamboo skewers, and achieve fast skewering through a precise structure, ensuring that the meat skewers are uniform and beautiful. It solves the problems of low efficiency, easy to prick hands, and poor hygiene of manual skewering, helping enterprises reduce costs, improve efficiency, and stabilize production.
[0003] When using a tenderloin skewer machine, if the fixed pressing plate cannot be adapted to different tenderloins (such as thickness, differences in stickiness after marinating) or other meat products (such as lamb and chicken), unstable pressing can easily occur, affecting the skewering quality. Therefore, we need to design a tenderloin skewer machine with a positioning skewer structure that can quickly replace pressing plates of different materials and structures to adapt to tenderloins of different thicknesses, marinated and fresh meat products, and expand to include lamb and other categories. Worn or residual plates can be directly disassembled and replaced without downtime for major repairs. A suitable pressing plate can fix the tenderloin meat, etc., with relatively stable pressure, and the positioning skewer will not shift. Utility Model Content
[0004] The purpose of this invention is to provide a skewer machine for tenderloin with a positioning skewer structure. It has the advantages of a replaceable pressing plate design, which enables compatibility with multiple types of meat, quick replacement of wear plates, ensuring skewer quality, relatively stable pressure, and positioning skewer without deviation, thereby solving the aforementioned technical problems.
[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A positioning skewer structure for skewering tenderloin includes a meat slot placed on the top of the skewering machine. A skewering power housing is fixedly connected to both sides of the top of the skewering machine. A skewering execution component is installed in the inner cavity of the skewering power housing.

A rectangular block is fixedly connected to the central axis at the bottom of the connecting plate. A mounting plate is fixedly connected to the top of the pressing plate by bolts. A locking component is fixedly connected to the top of the mounting plate. Four sliding grooves are fixedly connected to the left and right sides of the locking component. Positioning screws are provided through the surfaces of the rectangular block, side blocks, and locking component. A reinforcing member is fixedly connected to the front side of the locking component by a connecting post. The two ends of the reinforcing member are fixedly connected to the rectangular plate by bolts.
[0006] Preferably, two symmetrical rectangular plates are provided on the front and rear sides of the rectangular block, the tops of the two rectangular plates are fixedly connected to the connecting plate, and the rectangular plates are slidably connected to the front and rear sides of the engaging component.
[0007] Preferably, two symmetrical side blocks are provided on the left and right sides of the rectangular block, the two side blocks are fixedly connected to the connecting plate, and the side blocks are slidably connected to the left and right sides of the engaging member.
[0008] Preferably, sliders are fixedly connected to both the front and rear sides of the two side blocks, and the four sliding grooves are slidably connected to the sliders.
[0009] Preferably, a connecting block is fixedly connected to the rear surface of the positioning screw, and the connecting block is slidably connected to the rectangular block, the side stop block and the locking member.

[0021] In the following description, embodiments of the positioning and threading structure rib threading machine of this utility model will be described with reference to the accompanying drawings.
[0022] Figure 1-5 This invention illustrates a positioning skewer structure for skewering pork tenderloin according to an embodiment of the present invention. It includes a meat slot 2 placed on top of the skewering machine 1. A skewering power housing 3 is fixedly connected to both sides of the top of the skewering machine 1. A skewering execution component 4 is installed inside the cavity of the power housing 3. A pressing plate 5 is provided at the bottom of the skewering execution component 4. A connecting plate 6 is fixedly connected to the bottom of the skewering execution component 4. A rectangular block 7 is fixedly connected to the central axis at the bottom of the connecting plate 6. Two symmetrical side blocks 9 are provided on the left and right sides of the rectangular block 7. The two side blocks 9 are fixedly connected to the connecting plate 6 and slidably connected to the left and right sides of the locking component 12. A mounting plate 11 is fixedly connected to the top of the pressing plate 5 by bolts. A locking component 12 is fixedly connected to the top of the mounting plate 11. Two symmetrical rectangular plates 8 are provided on the front and rear sides of the rectangular block 7. The tops of the two rectangular plates 8 are fixedly connected to the connecting plate 6 and slidably connected to the front and rear sides of the locking component 12. Four sliding grooves 13 are fixedly connected to the left and right sides of the rectangular block 7, and sliders 10 are fixedly connected to the front and rear sides of the two side blocks 9. The four sliding grooves 13 are slidably connected to the sliders 10. Through the cooperation of the sliders 10 and the sliding grooves 13, the sliding grooves 13 guide the sliders 10 when the side blocks 9 slide on the surface of the locking part 12, ensuring that the side blocks 9 will not deviate when sliding, and improving the stability of the locking part 12 when the side blocks 9 are locked. The rectangular block 7, the side blocks 9 and the locking part 12 are provided with positioning screws 14 through the surface. The front side of the locking part 12 is fixedly connected to the reinforcing member 16 through the connecting post. The two ends of the reinforcing member 16 are fixedly connected to the rectangular plate 8 through bolts. The rear side of the positioning screw 14 is fixedly connected to the connecting block 15. The connecting block 15 is slidably connected to the rectangular block 7, the side blocks 9 and the locking part 12. A rectangular groove for the connecting block 15 to slide is opened on one side of the rectangular block 7, the side blocks 9 and the locking part 12.
[0023] Working Principle: In use, the tenderloin skewer machine 1 carries and transports the tenderloin raw material to the processing position. The meat slot 2 precisely positions the tenderloin and skewer track, ensuring uniform piercing positions. Then, the output driving force of the skewer execution component 4 within the skewer power housing 3 drives the pressing plate 5 to complete the skewer piercing action. Each step starts with conveying, ensures accuracy through positioning, and is driven by power transmission, seamlessly connecting to complete the tenderloin skewering operation. When the pressing plate 5 needs to be disassembled and replaced, the positioning screw 14 is rotated. Due to the downward placement of the connecting block 15, it aligns with the rectangular block... 7. The rectangular grooves on one side of the side stop block 9 and the locking piece 12 are not aligned. Then, rotate the positioning screw 14 so that the placement of the connecting block 15 is aligned with the direction of the rectangular groove. Pull the positioning screw 14, and the positioning screw 14 will cause the connecting block 15 to disengage from the rectangular block 7, the side stop block 9 and the locking piece 12. At this time, the connection position is relatively loose. Remove the bolts on both sides of the reinforcing member 16, and then the pressing plate 5 will cause the locking piece 12 to disengage from the rectangular block 7 through the mounting plate 11. Then, the user can replace the pressing plate 5 with a suitable one and install it at the bottom of the tack-piercing assembly 4.
[0024] In summary, this positioning and skewering structure for tenderloin skewering machine, through the coordinated use of the pressing plate 5, rectangular block 7, and locking component 12, allows the pressing plate 5 to be disengaged from the connecting plate 6 at the bottom of the skewering execution component 4. This enables the replacement of the pressing plate 5 connected to the bottom of the skewering execution component 4. Thus, the replaceable pressing plate design achieves compatibility with multiple types of meat, rapid replacement of worn plates, ensures skewering quality, provides relatively stable pressure, and prevents misalignment during positioning and skewering.
