[0026] In view of the problems mentioned in the above background technology, the embodiment of the utility model provides a trimming device for an extruder to solve the above technical problems, and its technical solution is as follows:
[0027] A trimming device for an extruder, comprising:
[0028] The bracket 110, the table 111, the lower adjustment plate 120, the upper adjustment plate 130, the top plate 140, the motor 151, the cylinder 152, the bidirectional lead screw 170, the guide column 160 and the cutter 180;
[0029] The table 111 is fixed on the bracket 110;
[0030] The guide pillars 160 include two, and the two guide pillars 160 are fixed on the table 111 at intervals;
[0031] The top plate 140 is fixed on the top of the two guide pillars 160;
[0032] The two bidirectional screws 170 include two bidirectional screws 170, which are arranged vertically at intervals, and the two ends of the bidirectional screws 170 are rotatably connected to the table 111 and the top plate 140 respectively; the two bidirectional screws 170 are located between the two guide pillars 160;
[0033] The upper adjustment plate 130 and the lower adjustment plate 120 are located between the table 111 and the top plate 140, and the upper adjustment plate 130 is located above the lower adjustment plate 120; the two sides of the upper adjustment plate 130 and the lower adjustment plate 120 are respectively slidably connected to the two guide pillars 160 and are respectively threadedly connected to the two bidirectional lead screws 170; the same side ends of the upper adjustment plate 130 and the lower adjustment plate 120 are respectively located on two sections of reverse threads of a bidirectional lead screw 170;
[0034] The motor 151 includes two motors 151, which are respectively fixed on the top plate 140, and each motor 151 drives and connects a bidirectional lead screw 170;
[0035] The cylinder 152 is fixed on the top plate 140 and is located between the two motors 151, and the driving rod of the cylinder 152 passes through the top plate 140 downward;
[0036] The cutter 180 is located below the top plate 140 and fixed to the end of the driving rod of the cylinder 152; the upper adjustment plate 130 is provided with a channel 131 through which the cutter 180 passes.
[0037] In this embodiment, the two sides of the middle of the channel 131 protrude outward to form arc grooves 131a; when the driving rod of the cylinder 152 is extended to drive the cutter 180 to move downward, the design of the arc groove 131a can facilitate the passage of the driving rod of the cylinder 152 to avoid interference with the movement of the driving rod of the cylinder 152.
[0038] In this embodiment, the bracket 110 includes vertical poles and horizontal poles; there are four vertical poles, and the horizontal poles are fixedly connected between adjacent vertical poles.
[0039] The working principle of the trimming device of an extruder provided by the embodiment of the utility model is as follows:
[0040] 1. As Figure 1-3 As shown, the trimming device is installed at the extrusion port of the extruder 200, and ensures that the sheet extruded by the extruder can pass through the position between the two bidirectional lead screws 170;
[0041] 2. When the extruder 200 performs sheet extrusion operation, when the length of the extruded sheet reaches the specified length, the two motors 151 work to drive the upper adjustment plate 130 and the lower adjustment plate 120 to move toward each other along the height direction of the guide pillar 160 and instantly clamp the extruded sheet;
[0042] 3. When the sheet is clamped by the upper adjustment plate 130 and the lower adjustment plate 120, the cylinder 152 drives the rod to extend and drives the cutter 180 to move downward and pass through the channel 131 on the upper adjustment plate 130 to cut the sheet, so as to achieve smooth slicing of the cut surface of the sheet;
[0043] 4. Then the cylinder 152 drives the rod to contract and drives the cutter 180 to move upward and reset; at the same time, the two motors 151 work to drive the upper adjustment plate 130 and the lower adjustment plate 120 to move in the opposite direction along the height direction of the guide column 160 and reset;
[0044] 5. When the extruder continues to extrude the sheet and reaches the specified length, repeat steps 2 to 4 to complete the sheet cutting operation.
[0045] The embodiment of the utility model provides a trimming device for an extruder, which has the following beneficial effects: The utility model designs a trimming device for an extruder, which can slice the cut surface of a sheet material smoothly, improve product quality, and facilitate operation.
