Description

Technical Field

[0001] This utility model mainly relates to the field of refrigerator partition technology, specifically a cutting device for processing refrigerator partitions. Background Technology

[0002] Simply put, a refrigerator shelf is a flat panel installed inside a refrigerator. It is a structural component used to divide the internal space of the refrigerator, dividing the refrigerator compartment or freezer compartment into different areas in the vertical direction, so as to more effectively organize and store various foods, drinks and other items.

[0003] Refrigerator shelves need to be cut before use. Existing cutting devices often produce burrs and chipped edges at the cut. Burrs and chipped edges make the shelves look rough and irregular, ruining the overall smoothness and neatness. At the same time, burrs may scratch the user's hand, posing a certain safety hazard. Chipped edges can weaken the structural strength of the shelves, making them more prone to damage when bearing heavy objects. Utility Model Content

[0004] The purpose of this invention is to solve the problem that burrs and chipping are easily produced after the cutting device cuts the refrigerator partition, which affects the use of the partition. Therefore, a cutting device for processing refrigerator partitions is proposed.

[0024] To facilitate understanding of this utility model, a more comprehensive description of the utility model will be given below with reference to the accompanying drawings, which show several embodiments of the utility model. However, the utility model can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the disclosure of the utility model more thorough and comprehensive.

[0025] Please refer to the appendix carefully. Figures 1-4As shown, this utility model provides a technical solution: a cutting device for processing refrigerator partitions, including a housing 10, a conveying mechanism inside the housing 10, two symmetrically arranged support plates 20 on the upper end of the conveying mechanism on the housing 10, a cutting blade 23 on the side of the two support plates 20 that are close to each other, a fixing plate 24 on the side of the two cutting blades 23 that are close to each other, and a grinding mechanism on the side of the two fixing plates 24 that are close to each other. The grinding mechanism includes four grinding blocks 30 that are slidably installed on the fixing plates 24, and the four grinding blocks 30 are symmetrically arranged with the center of the fixing plate 24 as the center.

[0026] By setting four grinding blocks 30, when the refrigerator shelf is cut, the refrigerator shelf moves to the cutting blade 23 for cutting. Then, the grinding blocks 30 close to the surface of the refrigerator shelf come into contact with the refrigerator shelf. As the cutting blade 23 cuts, the four grinding blocks 30 simultaneously grind the burrs and chipped edges at the cut, which can eliminate the burrs or chipped edges at the cut.

[0027] In one embodiment of this utility model, such as Figure 2 and 4 As shown, the polishing mechanism also includes four fixed blocks 301 fixedly installed at one end of the four polishing blocks 30 close to each other. The fixed plate 24 has four elongated holes 241. The fixed blocks 301 are slidably installed in the elongated holes 241. A slide rod 31 is fixedly installed in the elongated hole 241. The slide rod 31 passes through the fixed block 301 and is slidably connected to the fixed block 301. A spring 32 is fixedly installed between the fixed block 301 and the inner wall of the elongated hole 241. The spring 32 is slidably sleeved on the outer surface of the slide rod 31. When encountering a thicker refrigerator shelf, the polishing block 30 contacts the surface of the refrigerator shelf, causing the fixed block 301 to slide and compress the spring 32 in the elongated hole 241, so that the four polishing blocks 30 can adapt to polishing refrigerator shelves of different thicknesses.

[0028] In one embodiment of this utility model, such as Figure 2 and 4 As shown, a circular gear 33 is rotatably mounted on the fixed plate 24. Each of the four grinding blocks 30 has a long toothed rod 34 fixedly connected to one side of the circular gear 33. The four long toothed rods 34 mesh with the circular gear 33 respectively. The two adjacent long toothed rods 34 on the four grinding blocks 30 are arranged to overlap vertically to avoid the four long toothed rods 34 from colliding when moving.

[0029] Specifically, when polishing a thicker refrigerator shelf, one of the polishing blocks 30 contacts the surface of the refrigerator shelf, causing the fixing block 301 to slide and compress the spring 32 within the elongated hole 241. At the same time, the long toothed rod 34 on the polishing block 30 pushes the sprocket 33 on the fixing plate 24 to rotate. Furthermore, the other three long toothed rods 34, along with the rotation of the sprocket 33, pull the other three polishing blocks 30 to be in the same position as the polishing block 30 during rotation. Since the polishing blocks 30 rotate with the cutting disc 23 at a relatively fast speed, it is possible to have all four polishing blocks 30 polishing the thicker refrigerator shelf.

[0030] In one embodiment of this utility model, such as Figure 2 and Figure 3 As shown, a rotating block 21 is rotatably mounted on the support plate 20. A third motor 22 is fixedly mounted on one side of the support plate 20. The output end of the third motor 22 is fixedly connected to the rotating block 21. Four first locking holes 211 are evenly opened along the circumference of the rotating block 21 at the end away from the third motor 22. Four first locking blocks 231 are fixedly connected to the lower end of the cutting blade 23. The four first locking blocks 231 are respectively engaged with the four first locking holes 211. Two second locking holes 232 are opened at the upper end of the cutting blade 23. Two second locking blocks 242 are fixedly connected to both sides of the lower end of the fixing plate 24. The two second locking blocks 242 are respectively engaged with the two second locking holes 232. Through the engagement of the first locking holes 211 with the first locking blocks 231 and the engagement of the second locking holes 232 with the second locking blocks 242, the fixing plate 24 and the cutting blade 23 will rotate synchronously with the rotating block 21.

[0031] In one embodiment of this utility model, such as Figure 2 and Figure 3 As shown, the rotating block 21 has a threaded hole 212 in the middle of the four first locking holes 211. A threaded rod 25 is installed in the threaded hole 212. The end of the threaded rod 25 away from the rotating block 21 passes through the cutting blade 23, the fixing plate 24 and the spur gear 33 respectively and is fixedly connected to the knob 26. The threaded engagement between the threaded rod 25 and the threaded hole 212 facilitates the assembly and disassembly of the cutting blade 23 and the fixing plate 24.

[0032] In one embodiment of this utility model, such as Figure 1 As shown, the conveying mechanism includes two rotating shafts 12 rotatably installed inside the housing 10. Rollers 13 are fixedly sleeved on both rotating shafts 12. A conveyor belt 14 is sleeved on the two rollers 13. Several baffles 15 are evenly fixedly arranged on the conveyor belt 14. A first motor 16 is fixedly installed on one side of the housing 10. The output end of the first motor 16 passes through the housing 10 and is rotatably connected to one of the rotating shafts 12. Two cutting blades 23 are located at both ends of the conveyor belt 14.

[0033] Specifically, the refrigerator shelf to be cut is placed on the conveyor belt 14 between adjacent baffles 15. The first motor 16 is started to drive one of the rotating shafts 12 to rotate. Under the transmission of the two rollers 13 and the conveyor belt 14, the baffles 15 push the refrigerator shelf to the position of the cutting blade 23 for cutting.

[0034] In one embodiment of this utility model, such as Figure 1 As shown, pads 101 are fixedly connected to the inner walls of both sides of the housing 10. The two pads 101 are respectively attached to the two ends of the conveyor belt 14 on the side that is close to each other. A collection box 11 is slidably installed at the bottom of the housing 10. The serrations of the two cutting blades 23 are respectively attached to the upper surfaces of the two pads 101. By setting the two pads 101, the cutting blades 23 support the refrigerator shelf when cutting the refrigerator shelf. The cut edges and debris fall into the collection box 11 below the housing 10 through the gap between the conveyor belt 14 and the housing 10 for centralized collection.

[0035] In one embodiment of this utility model, such as Figure 1 As shown, support frames 17 are fixedly installed on the upper ends of both sides of the housing 10. A bidirectional lead screw 18 is rotatably installed between the two support frames 17. The threads at both ends of the bidirectional lead screw 18 are set in opposite directions. The two ends of the bidirectional lead screw 18 pass through the two support plates 20 respectively and are threadedly connected to the two support plates 20. A second motor 19 is fixedly installed on one of the support frames 17. The output end of the second motor 19 passes through one of the support frames 17 and is fixedly connected to the bidirectional lead screw 18. By starting the second motor 19, the bidirectional lead screw 18 is driven to rotate, so that the two support plates 20 move relative to each other on the bidirectional lead screw 18, which facilitates the adjustment of the cutting width of the refrigerator shelf.

[0036] In one embodiment of this utility model, such as Figure 1 As shown, a limiting rod 171 is fixedly installed between the two support frames 17 at the lower end of the bidirectional lead screw 18. The limiting rod 171 passes through the two support plates 20 and is slidably connected to the two support plates 20. By setting the limiting rod 171, the support plates 20 are prevented from deflecting as the bidirectional lead screw 18 rotates.

[0037] The present invention has been described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
