[0023] Specifically, the opening and closing assembly 7 includes a fixing bar 71, a spring 72, a pressing plate 73, a connecting plate 74, a fixing plate 75, a connecting block 76 and a supporting block 77, wherein a fixing bar 71 is provided on one side of the interior of the workbench 1, a spring 72 is provided inside the fixing bar 71, a pressing plate 73 is provided at the upper end of the spring 72, connecting plates 74 are symmetrically provided on both sides of the pressing plate 73, a fixing plate 75 is provided at one end of the connecting plate 74, a connecting block 76 is provided at the lower end of the fixing plate 75, and a supporting block 77 is provided at the lower end of the connecting block 76.

[0024] By adopting the above technical solution, when the cutting saw blade 6 needs to be taken out, the pressing plate 73 is pushed downward to drive the connecting plate 74 and the fixing plate 75 to move downward, and the fixing plate 75 drives the connecting block 76 to rotate around the supporting block 77, so that one end of the fixing plate 75 does not block the cutting saw blade 6, and the cutting saw blade 6 can be taken out.

[0025] Specifically, a through hole is disposed at the inner upper end of the fixing bar 71 , and limiting rods are symmetrically disposed inside the pressing plate 73 .

[0026] By adopting the above technical solution, when the pressing plate 73 moves, the staff can pass their fingers through the through hole to push the pressing plate 73, and the limit rod can ensure that the pressing plate 73 does not tilt.

[0027] When this embodiment is in use: the pressing plate 73 is pushed downward to drive the connecting plate 74 and the fixing plate 75 to move downward, and the fixing plate 75 drives the connecting block 76 to rotate around the supporting block 77, so that one end of the fixing plate 75 does not block the cutting saw blade 6, and the cutting saw blade 6 can be taken out. When the pressing plate 73 moves, the staff can push the pressing plate 73 through the through hole with their fingers, and the limit rod can ensure that the pressing plate 73 does not tilt.

[0028] Example 2

[0029] The present embodiment is different from the embodiment 1 in that: specifically, the burr collection assembly 8 includes a collection box 81, a dust hood 82, a delivery pipe 83, a bottom cover 84, a fan 85, a fixed sleeve 86 and a filter 87, wherein a collection box 81 is provided at the lower end of the workbench 1, delivery pipes 83 are symmetrically provided on both sides of the collection box 81, a dust hood 82 is provided at the upper end of the delivery pipe 83, a bottom cover 84 is provided at the lower end of the collection box 81, a fan 85 is provided inside the bottom cover 84, a fixed sleeve 86 is provided at the upper end of the fan 85, and a filter 87 is provided inside the fixed sleeve 86.

[0030] By adopting the above technical solution, when collecting burrs, start the fan 85 to blow the air inside the collection box 81 out from the filter 87, and the outside air drives the burrs into the dust hood 82, and the burrs are brought into the collection box 81 through the conveying pipe 83. The burrs will fall on the upper surface of the bottom cover 84 due to gravity, thereby realizing the collection of burrs.

[0031] Specifically, partitions are symmetrically arranged inside the collection box 81 , and the partitions are inclined relative to the inner upper end of the collection box 81 .

[0032] By adopting the above technical solution, when using the burr collection assembly 8, the partition can prevent the burrs from falling on the surface of the filter screen 87 and causing blockage, and the inclined partition can guide the burrs to fall on the upper end surface of the bottom cover 84.

[0033] Specifically, a baffle plate is provided on one side of the upper end of the bottom cover 84, and bolts are provided inside the baffle plate.

[0034] By adopting the above technical solution, when processing the burrs, the staff can turn the bolts to disengage them from the inside of the enclosure plate, and then pull the bottom cover 84 downward to drive the enclosure plate out, making it easier to process the burrs.

[0035] When this embodiment is in use: start the fan 85 to blow the air inside the collection box 81 out from the filter 87, and the outside air drives the burrs into the dust hood 82, and the burrs are brought into the collection box 81 through the conveying pipe 83. The burrs will fall on the upper surface of the bottom cover 84 due to gravity, thereby collecting the burrs. When using the burr collection assembly 8, the partition can prevent the burrs from falling on the surface of the filter 87 and causing blockage, and the inclined partition can guide the burrs to fall on the upper surface of the bottom cover 84. When processing the burrs, the staff can turn the bolts to disengage them from the inside of the baffle plate, and then pull the bottom cover 84 downward to drive the baffle plate out, which is convenient for processing the burrs.

[0036] The fan 85 in the present invention is an existing disclosed technology, and the selected model is FDG1B5010H12.

[0037] The structure and use principle of the workbench 1, top plate 2, cylinder 3, cutting knife 4, lower pressure plate 5 and cutting saw blade 6 in the present invention have been disclosed in a loom weaving edge trimming device disclosed in Chinese patent application No. 202322252173.X.

[0038] The working principle and use process of the present invention are as follows: when the weaving cloth trimming device of the loom is in use, the pressing plate 73 is pushed downward to make it drive the connecting plate 74 and the fixing plate 75 to move downward, and the fixing plate 75 drives the connecting block 76 to rotate around the supporting block 77, thereby making one end of the fixing plate 75 not block the cutting saw blade 6, and the cutting saw blade 6 can be taken out. When the pressing plate 73 moves, the staff can push the pressing plate 73 through the through hole with their fingers, and the limit rod can ensure that the pressing plate 73 does not tilt. When collecting the burrs, the fan 85 is started to blow the air inside the collection box 81 to be discharged from the filter screen 87, and the outside air drives the burrs to enter the dust collection cover 82, and the burrs can be brought into the collection box 81 through the conveying pipe 83. The burrs will fall on the upper end surface of the bottom cover 84 due to the action of gravity, thereby realizing the collection of the burrs. When processing the burrs, the staff can turn the bolts to make it detach from the inside of the baffle plate, and then pull the bottom cover 84 downward to drive the baffle plate to be taken out, which is convenient for processing the burrs.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
