Description

Technical Field

[0001] The utility model belongs to the technical field of glass fiber cutting, in particular to a glass fiber chopped strand cutting device. Background Art

[0002] Glass fiber chopped strand cutting equipment, commonly known as a glass fiber chopper or fiber cutting machine, is a device specifically used to cut glass fiber chopped strands. When using a chopper to cut glass fiber, the cutter needs to come into rapid and repeated contact with the glass fiber, which can easily lead to increased tool fatigue, thereby shortening its service life and requiring frequent replacement. However, the cutters on most choppers are set inside a protective cover, and the process of replacing the cutters is time-consuming and labor-intensive, which not only reduces the convenience of tool replacement but also affects processing efficiency.

[0003] After searching, the Chinese patent with announcement number CN221518099U discloses a glass fiber chopping machine, including a main body for chopping glass fibers, a conveyor belt is provided on the inner side of the main body, a protective cover is installed on the top of the main body, and fixed frames are installed on both sides of the protective cover. The two fixed frames are jointly provided with two sliding rods, and the outer walls of the two sliding rods are jointly provided with two connecting frames. The top of the connecting frame is provided with a first fixing assembly, and the inner top of the connecting frame is installed with a hydraulic rod. The telescopic end of the hydraulic rod is installed with a mounting plate, and the mounting plate is connected to a cutting knife through a second fixing assembly.

[0004] Although the glass fiber cutting equipment in the above-mentioned prior art can realize the replacement of the cutting knife through the cooperation of the first fixing component and the second fixing component, there are still some shortcomings in actual use. For example, after the two connecting frames on the slide rod slide, the screw rod is tightened against the slide rod by rotating the knob on the upper end of the connecting frame. In practice, this traditional operation method requires staff to assist in fixing both the lower and upper knives, which is relatively cumbersome and inconvenient. Secondly, when the cutting knife is cutting, both hands need to press the first elastic block on the positioning rod at the same time, and then the cutting knife needs to be pulled out from the positioning rod, which is difficult to operate. Utility Model Content

[0005] In view of the problems mentioned in the background technology, the purpose of the present invention is to provide a glass fiber chopped strand cutting device to solve the problems mentioned in the background technology.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions:

[0007] A glass fiber chopped strand cutting device comprises: a hood, wherein mounting slots are symmetrically formed on left and right sides of the hood, a knife shifting mechanism is fixedly mounted inside the mounting slots, a cutting knife is clamped to the lower end of the knife shifting mechanism via a fixing mechanism, and a control module is fixedly mounted on the front of the hood;

[0008] The cam is fixedly mounted on the side of the drive shaft of the driving mechanism, and the cam is connected to the drive shaft by a screw thread on the side of the drive shaft by the screw thread on the outside of the driving mechanism. The cam is fixedly mounted on the side of the drive shaft by the screw thread on the outside of the driving mechanism. The cam is fixedly mounted on the side of the drive shaft

[0009] The fixing mechanism includes an installation cavity, which is symmetrically opened on the inner side of the assembly plate. The inner side of the installation cavity is slidably connected to the installation plate. A clamping block is fixedly installed on the lower end of the installation plate. The clamping end of the clamping block movably passes through the cavity wall of the installation cavity. The clamping end of the clamping block is arranged on the side of the cutting knife away from the limit plate. A pull rod is fixedly installed on the upper end of the installation plate. A spring is sleeved on the end of the pull rod close to the installation plate. The end of the pull rod away from the spring slides through the cavity wall of the installation cavity and is fixed with the same pull handle.

[0010] As a preferred technical solution, a sliding rod is symmetrically fixedly installed at the concave part of the lower end of the mounting frame, and the movable frame is slidably connected to the outside of the sliding rod.

[0011] As a preferred technical solution, a screw sleeve is fixedly installed on the inner side of the movable frame, and the movable frame is threadedly connected to the outer side of the screw rod through the screw sleeve.

[0012] As a preferred technical solution, positioning holes are symmetrically opened on the inner side of the cutting knife, and the cutting knife is plugged into the positioning rod through the positioning hole.

[0013] As a preferred technical solution, one end of the positioning rod away from the limiting plate is fixedly connected to a guide block, and the shape of the guide block is spherical.

[0014] As a preferred technical solution, a first sliding groove is symmetrically provided at the concave portion of the lower end of the movable frame, and a first slider is symmetrically fixedly connected to the end of the assembly plate, and the first slider and the first sliding groove are slidably connected.

[0015] As a preferred technical solution, a second sliding groove is symmetrically opened on the inner side of the installation cavity, a second slider is fixedly installed on the outer side of the installation plate, and the second slider and the second sliding groove are slidably connected.

[0016] In summary, the present invention has the following beneficial effects:

[0017] First, the control module controls the driving motor so that the output end of the driving motor drives the screw to rotate on the mounting frame, and the rotation of the screw causes the two movable frames connected by the outer thread to slide to the left synchronously. At this time, the cutting knife on the right half of the screw will move to the processing position to continue processing. At the same time, the cutting knife on the left half of the screw can be removed from the mounting slot on the left side of the machine cover for replacement. Conversely, when the cutting knife on the right half of the lower end of the screw needs to be replaced, the two movable frames move right against the mounting frame, and the cutting knife can be replaced from the right side of the machine cover, so that the cutting knife can be quickly and conveniently mounted and lowered.

[0018] Secondly, insert the cutting knife into the positioning rod of the limit plate at the lower end of the assembly plate. During the process of pushing it in horizontally, the insertion side of the cutting knife presses the inclined surface of the clamping block, causing the mounting plate connected to the clamping block to slide in the mounting cavity and compress the spring. When the cutting knife passes over the clamping block, the clamping block is elastically reset by the spring and is fixed on the other side of the cutting knife. When removing, only one hand is needed to pull the handle on the assembly plate. The handle drives the pull rods at two places to move up at the same time, and the pull rod drives the clamping block connected to the mounting plate to retract into the mounting cavity. At this time, the cutting knife can be directly removed with the other hand, so that the cutting knife can be quickly disassembled and used. BRIEF DESCRIPTION OF THE DRAWINGS

The hood 1 of this technical solution can be mounted on the main body of a glass fiber chopping machine disclosed in Chinese Patent Publication No. CN221518099U;

[0025] The knife moving mechanism 4 includes a mounting frame 401, which is fixedly mounted on the inner side of the mounting slot 3 of the hood 1, and a screw 403 is rotatably connected to the inner side of the mounting frame 401. A driving motor 402 is fixedly mounted on the left end of the mounting frame 401, and one end of the screw 403 passes through the frame wall of the mounting frame 401 and is fixedly mounted on the output end of the driving motor 402. The outer side of the screw 403 is threadedly connected to a moving frame 404, and the moving frame 404 is slidably connected to the inner side of the mounting frame 401. An electric push rod 405 is fixedly mounted on the concave part of the lower end of the moving frame 404, and an assembly plate 406 is fixedly mounted on the output end of the electric push rod 405. The assembly plate 406 is slidably connected to the concave part of the lower end of the mounting frame 401, and a limiting plate 408 is fixedly mounted on the lower end of the assembly plate 406. A positioning rod 407 is symmetrically fixedly mounted on the front side of the limiting plate 408, and one end of the positioning rod 407 slides through the cutting The knife 5 and the fixing mechanism 9 are arranged on the inner side of the assembly plate 406. During use, when the left half of the cutting knife 5 of the screw rod 403 needs to be replaced, it is only necessary to control the driving motor 402 through the control module 2 so that the output end of the driving motor 402 drives the screw rod 403 to rotate on the mounting frame 401, and the rotation of the screw rod 403 causes the two movable frames 404 connected by the outer thread to slide left synchronously. At this time, the cutting knife 5 of the right half of the screw rod 403 will move to the processing position to continue processing. At the same time, the cutting knife 5 of the left half of the screw rod 403 is removed from the mounting groove 3 on the left side of the machine cover 1 for replacement operation. Conversely, when the right half of the cutting knife 5 at the lower end of the screw rod 403 needs to be replaced, the two movable frames 404 move right against the mounting frame 401. At this time, the cutting knife 5 can be replaced from the right side of the machine cover 1, so that the cutting knife 5 can be conveniently and quickly performed on and off the cutting knife.

[0026] The fixing mechanism 9 includes a mounting cavity 901, which is symmetrically arranged on the inner side of the assembly plate 406. The inner side of the mounting cavity 901 is slidably connected to the mounting plate 902. A clamping block 903 is fixedly installed on the lower end of the mounting plate 902. The clamping end of the clamping block 903 movably penetrates the cavity wall of the mounting cavity 901. The clamping end of the clamping block 903 is arranged on the side of the cutting knife 5 away from the limit plate 408. A pull rod 905 is fixedly installed on the upper end of the mounting plate 902. A spring 904 is sleeved on the end of the pull rod 905 close to the mounting plate 902.

When fixing the cutting knife 5, the cutting knife 5 is inserted into the fixed end of the limit plate 408 at the lower end of the assembly plate 406. When the cutting blade 5 passes over the block 903, the block 903 is elastically reset by the spring 904 and is fixed on the other side of the cutting blade 5. When the cutting blade 5 is disassembled, only one hand is required to pull the handle 906 on the assembly plate 406. The handle 906 simultaneously drives the pull rods 905 at the two locations to move upward, and the pull rod 905 drives the block 903 connected to the mounting plate 902 to retract into the mounting cavity 901. At this time, the other hand can directly remove the cutting blade 5, thereby facilitating the quick disassembly and assembly of the cutting blade 5.

[0027] refer to Figure 2 The lower end concave part of the mounting frame 401 is symmetrically fixed with a slide bar 6, and the mobile frame 404 is slidably connected to the outside of the slide bar 6. By sliding the mobile frame 404 on the slide bar 6 of the mounting frame 401, the stability of the mobile frame 404 can be improved.

[0032] Principle and advantages of use: During use, when the left half of the cutting blade 5 of the screw rod 403 needs to be replaced, it is only necessary to control the driving motor 402 through the control module 2 so that the output end of the driving motor 402 drives the screw rod 403 to rotate on the mounting frame 401, and the rotation of the screw rod 403 causes the two movable frames 404 connected by the outer thread to slide left synchronously, at this time, the cutting blade 5 of the right half of the screw rod 403 will move to the processing position to continue processing, and at the same time, the cutting blade 5 of the left half of the screw rod 403 can be moved out of the mounting slot 3 on the left side of the machine cover 1 for replacement operation. Conversely, when the right half of the cutting blade 5 at the lower end of the screw rod 403 needs to be replaced, the two movable frames 404 move right against the mounting frame 401, and the cutting blade 5 can be replaced from the right side of the machine cover 1.

[0033] When the cutting knife 5 is fixed, the cutting knife 5 is inserted into the positioning rod 407 of the limit plate 408 at the lower end of the assembly plate 406. During the process of pushing the cutting knife 5 in horizontally, the insertion side of the cutting knife 5 presses the inclined surface of the clamping block 903, so that the mounting plate 902 connected to the clamping block 903 slides in the mounting cavity 901 and compresses the spring 904. When the cutting knife 5 passes over the clamping block 903, the clamping block 903 is elastically reset by the spring 904 and is fixed to the other side of the cutting knife 5. When removing the cutting knife 5, only one hand is needed to pull the handle 906 on the assembly plate 406. The handle 906 drives the pull rods 905 at the two locations to move up at the same time, and the pull rod 905 drives the clamping block 903 connected to the mounting plate 902 to retract into the mounting cavity 901. At this time, the cutting knife 5 can be directly removed by the other hand.
