Technical Field
[0001] This utility model relates to the field of roller cutter technology, and in particular to a roller cutter for cotton processing. Background Technology
[0002] The front end of cotton processing machinery needs to shred the baled cotton for easier processing. The gap between the roller cutter and the feed plate allows the shredded cotton to be fed out. Currently, the feed plate needs to be made with the corresponding curvature according to the diameter of the roller cutter, and then completed through a series of machining processes such as milling machines and grinding machines.
[0003] Existing technologies often have the following drawbacks: After long-term use, when the roller cutter needs to be replaced, the traditional replacement method is to use bolts inserted into the mounting holes on the roller cutter for fixing. The installation process requires the use of external tools, and for some rusty bolts, it is difficult for workers to quickly disassemble the bolts, thus reducing the replacement efficiency of the roller cutter body.
[0004] Therefore, this utility model provides a roller cutter for cotton processing. Utility Model Content

[0029] Reference Figure 1 As shown, this utility model provides a technical solution: a roller cutter for cotton processing, including a roller cutter body 1, two mounting holes 2 on both sides of the roller cutter body 1, mounting structures 3 on both ends of the roller cutter body 1, and a protective structure 4 on the surface of the roller cutter body 1.
[0030] The specific setup and function of its installation structure 3 and protective structure 4 will be explained below.
[0031] Reference Figure 1-4As shown in this embodiment: the mounting structure 3 includes two mounting blocks 31 located on both sides of the roller cutter body 1. Two pre-drilled grooves 33 are formed on the upper surface of each mounting block 31. A U-shaped sliding frame 34 is slidably connected to the inner side of each groove 33. Two insertion rods 36 are fixedly connected to the surface of the sliding frame 34. The insertion rods 36 slide through the mounting block 31, and their dimensions are compatible with the dimensions of the mounting hole 2. By setting the mounting structure 3, the roller cutter body 1 is installed using a locking mechanism, improving the installation speed of the roller cutter body 1. The entire replacement process is simple to operate, greatly improving the efficiency of roller cutter replacement. A chamfer 32 is provided at the port of the mounting hole 2. The chamfer 32 at the port of the mounting hole 2 guides the insertion rods 36 to be inserted more smoothly into the mounting hole 2, further improving installation efficiency. A spring 35 is fixedly connected between the inner wall of the sliding frame 34 and the pre-drilled groove 33. Under the action of the spring 35, the sliding frame 34 allows the insertion rods 36 to extend normally out of the mounting block 31. A fixing block 37 is fixedly connected to the surface of the mounting block 31, and a rotating shaft 38 is fixedly connected to the surface of the fixing block 37. A support plate 39 is rotatably connected to the side wall of the rotating shaft 38. After pulling the slide frame 34 and retracting the insert rod 36 to the inside of the mounting block 31, the support plate 39 on the rotating shaft 38 can be rotated to a position facing the surface of the slide frame 34. At this time, the retracted slide frame 34 can be temporarily blocked. After retracting the four insert rods 36 to the inside of the mounting block 31 in sequence, it is convenient to install or remove the roller cutter body 1 between the two mounting blocks 31.
[0032] Reference Figure 1-2 and Figure 5 As shown, specifically, the protective structure 4 includes a protective frame 41 that fits over the outside of the roller cutter body 1. An elastic pad 42 is glued to the inner side of the protective frame 41, and the elastic pad 42 is located between the roller cutter body 1 and the protective frame 41. The protective frame 41, fitting over the outside of the roller cutter body 1, reduces wear between the roller cutter body 1 and the carriage during transportation, thereby improving the safety of transporting the roller cutter body 1. A screw 43 is threaded into the inside of the protective frame 41, sliding through the elastic pad 42. A rotating block 44 is fixedly connected to the upper end of the screw 43. Rotating the screw 43 threaded into the protective frame 41 makes the fixation between the protective frame 41 and the roller cutter body 1 more secure, further improving the safety of the roller cutter body 1 during transportation. An anti-slip washer 45 is glued to the lower end of the screw 43. The anti-slip washer 45 glued to the lower end of the screw 43 increases the friction with the elastic pad 42 or other contact surfaces when the screw 43 is tightened.
[0033] Working principle: When installing the roller cutter, first install the two mounting blocks 31 on both sides of the cotton processing equipment. At this time, under the action of the spring 35, the sliding frame 34 allows the insertion rod 36 to extend normally out of the mounting block 31. When installing the roller cutter body 1, align the mounting holes 2 on both sides of the roller cutter body 1 with the insertion rod 36. The size of the insertion rod 36 matches the mounting hole 2, allowing for easy insertion, thus quickly completing the installation of the roller cutter body 1 without the need for additional tools. The chamfer 32 at the port of the mounting hole 2 guides the insertion rod 36 to insert more smoothly into the mounting hole 2, further improving installation efficiency. When it is necessary to replace the roller cutter body 1, pull the sliding frame 34. The sliding frame 34 slides in the reserved groove 33, overcoming the spring 35. The elastic force of the spring pull retracts the insert rod 36 into the inner side of the mounting block 31. During the pulling of the sliding frame 34, to prevent accidental rebound, the support plate 39 connected to the rotating shaft 38 on the fixing block 37 on the surface of the mounting block 31 can be rotated to face the surface of the sliding frame 34, temporarily blocking and fixing the retracted sliding frame 34. After retracting all four insert rods 36 into the inner side of the mounting block 31, the old roller cutter body 1 can be easily removed and the new roller cutter body 1 installed. By setting the mounting structure 3 and using a locking mechanism to install the roller cutter body 1, the installation speed of the roller cutter body 1 is improved. The entire replacement process is simple to operate and greatly improves the efficiency of roller cutter replacement.
[0034] During the transportation of the roller cutter body 1, the protective frame 41 is fitted over the outside of the roller cutter body 1. The elastic pad 42 bonded to its inner side can fill the gap between the roller cutter body 1 and the protective frame 41. The elastic pad 42 can buffer the collision between the roller cutter body 1 and external objects such as the carriage during transportation, reducing wear. Rotating the screw 43 connected to the internal thread of the protective frame 41, the screw 43 passes through the elastic pad 42. Since the upper end of the screw 43 is fixedly connected to the rotating block 44, rotating the rotating block 44 can easily rotate the screw 43. The anti-slip washer 45 bonded to the lower end of the screw 43 can be used to tighten the screw. When the screw 43 is tightened, the friction between the screw and the elastic pad 42 or other contact surfaces is increased, making the fixation between the protective frame 41 and the roller cutter body 1 more secure. This further improves the safety of the roller cutter body 1 during transportation, avoids damage to the roller cutter due to improper protection, and ensures that the roller cutter is in good condition before being put into use. By setting the protective structure 4 and the detachable protective frame 41, the protection of the outside of the roller cutter is facilitated, and friction between the roller cutter and the carriage during transportation is avoided, thereby improving the safety of the roller cutter body 1 during transportation.
