[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In the present invention, the operator places the plastic tube to be cut in the arc-shaped slideway on the workbench, and then drives the electric cylinder to drive the push plate to press down on the support seat, and the push plate presses down to drive the lower pressing frame on the lower pressing member to move downward, and when the lower pressing frame moves downward, it will drive the support rod to move downward, and when the support rod moves downward in the slide groove on the support seat, it will drive the two straightening frames to move downward, so that the two straightening frames are clamped with the plastic tube on the arc-shaped slideway, and then the lower pressing frame continues to move downward, and the two ends of the support rod will contact with the bottom of the slide groove of the support seat and no longer move downward, and at this time the lower pressing frame will drive the two articulated frames to move, so that the two sliding frames are on the support The two sliding frames move in opposite directions on the support rod, and the opposite movements of the two sliding frames drive the straightening frame to pull the clamped plastic tube outward, thereby straightening the plastic tube in the arc-shaped slideway, so that the plastic tube is in a straightened state during cutting, and the cut plastic tube is horizontal at the cut end, thereby improving the cutting quality. The setting of the pressure spring ensures that when the support rod moves downward and does not contact the bottom of the slide groove of the support seat, the two sliding frames will not move on the support rod, so that the straightening frame at the bottom of the two sliding frames completes the clamping operation of the plastic tube before the straightening operation can be performed, thereby avoiding the straightening of the plastic tube during the clamping process of the straightening frame, which affects the processing of the plastic tube.

[0014] In the present invention, after the plastic tube is cut, the driving electric cylinder will drive the lower pressing frame to move upward, and the upward movement of the lower pressing frame will drive the two articulated frames to pull up. At this time, the support rod will not interfere with the bottom of the slide groove of the support seat, and the setting of the pressure spring will drive the sliding frame to retract to the original position. At this time, the straightening frame at the bottom of one of the sliding frames will directly detach from the plastic tube, and the other sliding frame will be restricted by the L-shaped slide groove on the limit plate, so that the other sliding frame can only move in the L-shaped slide groove. At this time, the other sliding frame will drive the straightening frame to clamp the clamped plastic tube and move forward, and then move to the intersection of the L-shaped slide grooves. When the plastic tube is cut, the sliding frame will move up and the straightening frame will be separated from the plastic tube. Through this arrangement, the next section of the plastic tube can be pushed forward during the process of resetting upward after cutting, so that the next section of the plastic tube can be cut, thereby achieving a continuous cutting effect. When the next section of the plastic tube moves forward, the plastic tube cut in the previous section can be pushed into the unloading chute for unloading. At the same time, the loading and unloading of the plastic tube are realized, thereby improving the overall efficiency of plastic tube processing and cutting. There is no need to use multiple sets of processing devices to complete cutting, loading, unloading and other operations, and the efficiency is greatly improved.

[0015] In the present invention, after the two straightening frames straighten the plastic tube, the lower pressing frame is driven by the driving electric cylinder to continuously press down. At this time, the downward movement of the lower pressing frame will drive the cutting frame to move down. The downward movement of the cutting frame enables the cutting knife to pass through the cross slot on the fixed frame to cut the plastic tube on the arc slideway, thereby completing the cutting operation of the plastic tube. By setting the direction-adjusting turntable, when the operator needs to cut the plastic tube horizontally or vertically, he only needs to lift the direction-adjusting turntable from the cutting frame and then rotate it. The rotation of the direction-adjusting turntable drives the fixed rod to rotate, thereby cutting The knife rotates to adjust the cutting direction of the cutting knife. After adjusting the direction, you only need to press down the clamping rod on the adjustment turntable and the groove on the cutting frame to lock it. The cutting direction of the cutting knife can be adjusted through this setting, so that the cutting knife can realize two cutting methods, horizontal cutting and vertical cutting, when cutting the plastic tube, and the direction is adjusted conveniently and quickly. The direction adjustment is achieved by clamping a number of clamping rods and grooves to avoid the phenomenon of the cutting knife being offset after long-term use, so that the cutting knife can fall stably without shaking when cutting.

[0016] In the present invention, before the lower pressing frame moves downward to drive the cutting knife to cut the plastic tube, the downward movement of the cutting frame will drive the two limiting rods to move the fixing frame downward, and the fixing frame will fix and press the part of the plastic tube to be cut, so that the plastic tube at the part to be cut is fixed by the pressing of the fixing frame, which further improves the stability of the cutting knife when cutting the plastic tube, and the magnetic block on the workbench and the magnet at the bottom of the limiting rod can enable the fixing frame to firmly fix the plastic tube, thereby avoiding the shaking of the plastic tube during the cutting process, which affects the cutting effect of the plastic tube.

[0028] The pressing member 3 comprises a pressing frame 31, a support rod 32, a pressure spring 33, two sliding frames 34 and two hinged frames 36.

The push plate 23 presses down and drives the lower pressing frame 31 on the lower pressing member 3 to move downward. When the lower pressing frame 31 moves downward, it will drive the support rod 32 to move downward. When the support rod 32 moves downward in the slide groove 211 on the support seat 21, it will drive the two straightening frames 37 to move downward, so that the two straightening frames 37 are clamped with the plastic tube on the arc-shaped slide 11, and then the lower pressing frame 31 continues to move downward, and the two ends of the support rod 32 will contact with the bottom of the slide groove 211 of the support seat 21 and no longer move downward. At this time, the lower pressing frame 31 will drive the two articulated frames 36 to move, so that the two The sliding frames 34 move in opposite directions on the support rod 32.

The setting of the pressure spring 33 ensures that when the support rod 32 moves downward and does not contact the bottom of the slide groove 211 of the support seat 21, the two sliding frames 34 will not move on the support rod 32, so that the straightening frames 37 at the bottom of the two sliding frames 34 can only perform the straightening operation after completing the clamping operation of the plastic tube, thereby avoiding the straightening of the plastic tube by the straightening frame 37 during the clamping process, which affects the processing of the plastic tube.

[0031] In this embodiment, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the side wall of the support seat 21 is also fixedly connected to a limiting plate 391, and the limiting plate 391 is provided with an L-shaped groove 392, and one of the sliding frames 34 is provided with a pulley 35, and the pulley 35 slides in cooperation with the L-shaped groove 392; after the plastic tube is cut, the driving electric cylinder 22 will drive the lower pressing frame 31 to move upward, and the upward movement of the lower pressing frame 31 will drive the two articulated frames 36 to pull up, at this time, the support rod 32 will not conflict with the bottom of the groove 211 of the support seat 21, and the setting of the pressure spring 33 will drive the sliding frame 34 to retract to its original position, and at this time, the straightening frame 37 at the bottom of one of the sliding frames 34 will be directly detached from the plastic tube, and the other sliding frame 34 will be limited by the L-shaped groove 392 on the limiting plate 391, so that the other sliding frame 34 can only be moved in the L The plastic tube 38 is moved in the L-shaped slot 392, at which time the other sliding frame 34 will drive the straightening frame 37 to move the clamped plastic tube forward, and then when it moves to the intersection of the L-shaped slot 392, the sliding frame 34 will move up to separate the straightening frame 37 from the plastic tube. Through this arrangement, the next section of the plastic tube can be pushed forward during the process of resetting upward after cutting, so that the next section of the plastic tube can be cut, thereby achieving a continuous cutting effect, and when the next section of the plastic tube moves forward, the plastic tube cut in the previous section can be pushed into the unloading slot 13 for unloading, thereby realizing the loading and unloading of the plastic tube, thereby improving the overall efficiency of plastic tube processing and cutting, and can complete cutting, loading, unloading and other operations without using multiple sets of processing devices, and the efficiency is greatly improved.

Through the setting of the direction-adjusting turntable 43, when the operator needs to cut the plastic tube horizontally or vertically, he only needs to lift the direction-adjusting turntable 43 from the cutting frame 41 and then rotate it. The rotation of the direction-adjusting turntable 43 drives the fixing rod 42 to rotate, thereby rotating the cutting knife 45 to adjust the cutting direction of the cutting knife 45. After adjusting the direction, it is only necessary to press the clamping rod 44 on the direction-adjusting turntable 43 and the groove 411 on the cutting frame 41 downward to adjust the cutting direction of the cutting knife 45.

[0034] The use method and advantages of the present invention: The use method of the plastic production workbench with cutting function based on multi-angle adjustment, the working process is as follows:

[0035] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7As shown: the operator places the plastic tube to be cut in the arc-shaped slideway 11 on the workbench 1, and then drives the electric cylinder 22 to drive the push plate 23 to press up and down on the support seat 21, and the push plate 23 presses down to drive the lower pressing frame 31 on the lower pressing member 3 to move downward, and when the lower pressing frame 31 moves downward, it will drive the support rod 32 to move downward, and when the support rod 32 moves downward in the slide groove 211 on the support seat 21, it will drive the two straightening frames 37 to move downward, so that the two straightening frames 37 are clamped with the plastic tube on the arc-shaped slideway 11, and then the lower pressing frame 31 continues to move downward, and the two ends of the support rod 32 will contact with the bottom of the slide groove 211 of the support seat 21 and no longer move downward, and at this time the lower pressing frame 31 will drive the two articulated frames 36 to move, so that The two sliding frames 34 move in opposite directions on the support rod 32. The opposite movement of the two sliding frames 34 drives the straightening frame 37 to pull the clamped plastic tube outward, thereby straightening the plastic tube in the arc slide 11, so that the plastic tube is in a straightened state during cutting, and the cut portion of the cut plastic tube is horizontal, thereby improving the cutting quality. The setting of the pressure spring 33 ensures that when the support rod 32 moves downward and does not contact the bottom of the slide groove 211 of the support seat 21, the two sliding frames 34 will not move on the support rod 32, so that the straightening frame 37 at the bottom of the two sliding frames 34 completes the clamping operation of the plastic tube before the straightening operation can be performed, thereby avoiding the straightening of the plastic tube by the straightening frame 37 during the clamping process, which affects the processing of the plastic tube.

[0036] When the two straightening frames 37 move downward under the drive of the lower pressing frame 31, the two clamping plates 38 at the bottom of the straightening frames 37 are initially inclined inward due to the setting of the torsion springs, and then during the continuous downward pressing process of the straightening frames 37, the two clamping plates 38 clamp the outer wall of the plastic tube, and then move on the support rod 32 through the sliding frame 34, so that the clamped plastic tube is straightened, thereby avoiding the uneven cutting of the plastic tube;

[0037] After the two straightening frames 37 straighten the plastic tube, the lower pressing frame 31 is continuously pressed down by the driving electric cylinder 22. At this time, the downward movement of the lower pressing frame 31 will drive the cutting frame 41 to move downward. The downward movement of the cutting frame 41 enables the cutting knife 45 to pass through the cross slot 511 on the fixing frame 51 to cut the plastic tube on the arc slide 11, thereby completing the cutting operation of the plastic tube. By setting the turning disk 43, when the operator needs to cut the plastic tube horizontally or vertically, he only needs to lift the turning disk 43 from the cutting frame 41 and then rotate it. The rotation of the turning disk 43 drives the fixing rod 42 to rotate, thereby causing the cutting knife 45 to cut the plastic tube on the arc slide 11. 45 is rotated to adjust the cutting direction of the cutting knife 45. After the direction is adjusted, the clamping rod 44 on the adjustment turntable 43 and the groove 411 on the cutting frame 41 are pressed down to lock the cutting direction of the cutting knife 45. Through this setting, the cutting direction of the cutting knife 45 can be adjusted, so that the cutting knife 45 can achieve two cutting modes of horizontal cutting and vertical cutting when cutting the plastic tube, and the direction adjustment is convenient and fast. The direction adjustment is carried out by the clamping cooperation of the clamping rods 44 and the grooves 411, which also avoids the phenomenon that the cutting knife 45 will be offset after long-term use, so that the cutting knife 45 can fall stably without shaking when cutting;

[0038] When the lower pressing frame 31 moves downward to drive the cutting knife 45 to cut the plastic tube, the downward movement of the cutting frame 41 will drive the two limiting rods 52 to move the fixing frame 51 downward, and the fixing frame 51 will fix and press the part of the plastic tube to be cut, so that the plastic tube at the part to be cut is fixed by the pressing of the fixing frame 51, further improving the stability of the cutting knife 45 when cutting the plastic tube, and the magnetic block 12 on the workbench 1 and the magnet at the bottom of the limiting rod 52 can make the fixing frame 51 firmly fix the plastic tube, avoiding the shaking of the plastic tube during the cutting process, which affects the cutting effect of the plastic tube;

[0039] After the plastic tube is cut, the driving electric cylinder 22 will drive the lower pressing frame 31 to move upward, and the upward movement of the lower pressing frame 31 will drive the two articulated frames 36 to pull up. At this time, the support rod 32 will not conflict with the bottom of the slide groove 211 of the support seat 21, and the setting of the pressure spring 33 will drive the sliding frame 34 to retract to the original position. At this time, the straightening frame 37 at the bottom of one of the sliding frames 34 will be directly separated from the plastic tube, and the other sliding frame 34 will be restricted by the L-shaped slide groove 392 on the limit plate 391, so that the other sliding frame 34 can only move in the L-shaped slide groove 392. At this time, the other sliding frame 34 will drive the straightening frame 37 to clamp the clamped plastic tube and move forward. , and then when it moves to the intersection of the L-shaped slide groove 392, the sliding frame 34 will move up, so that the straightening frame 37 is separated from the plastic tube. Through this arrangement, the plastic tube can be pushed forward in the process of resetting upward after cutting, so that the next section of the plastic tube can be cut, thereby achieving a continuous cutting effect, and when the next section of the plastic tube moves forward, the plastic tube cut by the previous section can be pushed into the unloading chute 13 to unload, and at the same time, the loading and unloading of the plastic tube is realized, thereby improving the overall efficiency of plastic tube processing and cutting, and can complete cutting, loading, unloading and other operations without using multiple sets of processing devices, and the efficiency is greatly improved.
