Description

Technical Field

[0001] This utility model relates to the field of food processing technology, and in particular to a cutting head mechanism for a strip cutting machine. Background Technology

[0002] When cutting potatoes into strips, people usually do it manually by holding a knife in their right hand and partially holding the potato in their left. Because it is done manually, it is impossible to control the uniformity of the size of each potato strip, resulting in a poor taste. In addition, cutting potatoes into strips manually is also slow.

[0003] A utility model patent with authorization announcement number CN213829179U discloses a potato slicing device, specifically an agricultural potato extrusion and slicing device. This device provides a fast and uniform potato slicing method for agricultural use. The device includes a base, a storage basket, a cutting mechanism, a conveying mechanism, a second support frame, and a servo motor. The storage basket is located on the upper front side of the base, the cutting mechanism is located on the upper left side of the base, the conveying mechanism is located on the upper right side of the base, and the second support frame is located on the upper right rear side of the base, with the servo motor mounted on the second support frame. This utility model achieves the effect of fast and uniform potato slicing for agricultural use. A pusher moves the potato within the cutting groove, cooperating with the cutting mesh, thereby uniformly extruding the potato into strips at a fast speed.

[0004] The applicant discovered that the existing cutter mesh is located at the front end of the equipment and is fixed by bolts. When the equipment is in normal operation, the cutter mesh is constantly subjected to lateral pushing force. Under the influence of this continuous lateral pushing force, the bolts used to fix the cutter mesh will bear a large pressure, causing the bolts to be easily damaged, broken or stripped, making the replacement and maintenance of the cutter mesh extremely troublesome.

[0006] To solve the above problems, the cutting head mechanism of the strip cutting machine involved in this utility model adopts the following technical solution:

[0007] This utility model provides a cutting head mechanism for a strip cutting machine, including a V-shaped guide seat and a mounting seat disposed at the end of the V-shaped guide seat. The mounting seat has a material channel that smoothly transitions with the material guide groove of the V-shaped guide seat. A cutting mesh for cutting the passing material into strips is installed on the material channel. It also includes an annular frame sleeved around the material channel. The edge of the annular frame extends towards the mounting seat and has a retaining edge welded to the mounting seat. The annular frame and the mounting seat form a working space for accommodating the cutting mesh. The cutting mesh is located in the working space, and the edge of the cutting mesh is aligned with the retaining edge. An opening for the cutting mesh to enter and exit is provided on the upper side of the working space.

[0008] Preferably, it further includes a positioning mechanism disposed between the mounting base and the annular frame. The positioning mechanism includes an annular top frame sleeved around the material channel, guide rods, and positioning posts. Multiple guide rods are equally spaced along one side of the annular top frame. The mounting base has positioning holes corresponding to the positions of any guide posts.

[0016] To make the technical objectives, technical solutions, and beneficial effects of this utility model clearer, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0017] The present invention provides a blade head mechanism for a strip cutting machine, as shown in the figure, comprising a V-shaped guide seat 1, a mounting base 2, a positioning mechanism, a cutting blade mesh 4, and an annular frame 5 arranged sequentially. Specifically:

[0018] The V-shaped guide seat 1 serves as the initial guiding component for material entering the cutter head mechanism. A V-shaped material guiding groove is provided on the V-shaped structure, offering a smooth track for material movement. This groove can position and guide materials of irregular shapes or different sizes, ensuring that the material is transported orderly along a predetermined path before entering the subsequent cutting stage. The mounting seat 2 is the supporting component of the cutter head mechanism. Material channels are provided on the mounting seat 2, connecting its opposite sides. The material channels smoothly transition to the material guiding groove of the V-shaped guide seat 1, allowing for a smooth transition from the guiding stage to the cutting stage without jamming due to abrupt changes in the channel, maintaining a stable material flow rate. The cutting mesh 4 is the executing component for cutting the material into strips, used to cut the material passing through the material channels into strips. The cutting mesh 4 includes an outer ring shell and blades arranged in a grid structure within the outer ring shell. All of the above structures are existing technologies.

[0019] The annular frame 5 is fitted around the material channel and is located on the side of the mounting base 2 away from the V-shaped structure. The edge of the annular frame 5 extends towards the mounting base 2 with a retaining edge 11. The retaining edge 11 of the annular frame 5 is welded to the mounting base 2. The annular frame 5 and the mounting base 2 form a working space to accommodate the cutter mesh 4. The retaining edge 11 is used to laterally limit the cutter mesh 4. Furthermore, the two ends of the retaining edge 11 extend along the edge of the annular frame 5 to the two ends of the middle part of the annular frame 5, that is, an opening for the cutter mesh 4 to enter and exit is opened on the upper side of the working space.

[0020] The positioning mechanism includes an annular top frame 6, guide rods 7, and positioning posts 8, which are sleeved around the material channel. Specifically, the annular top frame 6 is movably set in the working space, and the cutter mesh 4 is located between the annular frame 5 and the annular top frame 6. The axial projection of the annular top frame 6 is located on the outer shell of the cutter mesh 4. Multiple guide rods 7 are evenly spaced along one side of the annular top frame 6 (near the mounting base 2). The mounting base 2 has positioning holes that correspond to the position of any guide rod 7 and slide with it. That is, any guide rod 7 corresponds to a positioning hole on the mounting base 2, and the guide rod 7 can extend into it and slide back and forth along the axial direction of the positioning hole (the positioning hole is used to limit the radial movement of the guide rod 7 and limit it to only slide axially). When the annular top frame 6 slides back and forth away from or towards the annular frame 5, the guide rod 7 slides in the positioning hole, providing linear guidance for the movement of the annular top frame 6.

[0021] Furthermore, each guide rod 7 is fitted with a compression spring 9. The two ends of the compression spring 9 abut against the annular top frame 6 and the mounting base 2, respectively. As the guide rod 7 moves toward the positioning hole, the compression spring 9 is compressed and contracts. This structure utilizes the elastic force of the compression spring 9 to provide a continuous preload to the annular top frame 6, ensuring that it always fits tightly against the cutter mesh 4 and guarantees the stability of the cutter mesh 4 during the cutting process. The cutter mesh 4 is located between the annular top frame 6 and the annular frame 5. On the other side of the annular top frame 6 (facing the cutter mesh 4), multiple positioning posts 8 are circumferentially spaced at equal intervals. The outer ring shell of the cutter mesh 4 has positioning grooves that correspond one-to-one with the positions of the multiple positioning posts 8. When the cutter mesh 4 is inserted between the annular top frame 6 and the annular frame 5, the multiple positioning posts 8 are inserted into their corresponding positioning grooves to limit the movement of the cutter mesh 4 and effectively prevent the cutter mesh 4 from rotating during material cutting.

[0022] Furthermore, a handle 10 is provided at each of the left and right ends of the annular top frame 6, and a slide corresponding to the position of the handle 10 is provided on the edge. The two handles 10 pass through the edge through their corresponding slides, and the two handles 10 can move away from and towards the annular top frame 6 along the slides.

[0023] Finally, it should be noted that the above embodiments are only for illustration and not for limiting the technical solutions of this utility model. Any equivalent substitutions and modifications or partial substitutions that do not depart from the spirit and scope of this utility model should be covered within the scope of protection of the claims of this utility model.
