[0003] Place the injection-molded decorative strip with the waste material horizontally on top of the device, and clamp and fix the waste material on both sides. Then, depending on the sprue angle, select whether to adjust the angle of the shearing blade to cut the waste material and the sprue of the decorative strip.
[0004] Existing movable shearing gate devices for injection molding decorative strips are mostly used to shear horizontal gates at the junction of waste material and decorative strips. When it is necessary to shear non-horizontal gates, the existing shearing devices are inconvenient and affect the shearing efficiency of decorative strip gates. Therefore, a movable shearing gate device for injection molding decorative strips is proposed. Utility Model Content

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0023] Example 1
[0024] Reference Figures 1-4 This is the first embodiment of the present invention, which provides a device for moving and shearing the sprue of an injection-molded decorative strip, comprising: Base 1, with a movable part on top of base 1; Adjustment mechanism 2 is located on the top of the moving part. Adjustment mechanism 2 includes symmetrically arranged side plates 202. Hollow rotating shafts 204 are movably installed inside the two side plates 202 through bearing seats. Shearing blades 203 are installed on the outer surface of the hollow rotating shafts 204. Adjustment rods 206 are movably arranged inside the hollow rotating shafts 204. A side gear ring 208 is installed on one side of the side plate 202. A side gear plate 209 adapted to the side gear ring 208 is installed at one end of the adjustment rod 206. Arc-shaped limiting blocks 205 adapted to the adjustment rod 206 are circumferentially distributed on the inner surface of the hollow rotating shafts 204.
[0025] like Figure 4 As shown, in this embodiment, the side gear ring 208 is located on the outer surface of the side plate 202, which extends from one end of the hollow rotating shaft 204. The outer surface of the adjusting rod 206 is circumferentially provided with semi-arc grooves that are adapted to the arc-shaped limiting block 205. The arc-shaped limiting block 205 is movably connected inside the semi-arc groove. The side gear plate 209 is movably engaged inside the side gear ring 208. Under the action of multiple arc-shaped limiting blocks 205, when the adjusting rod 206 moves outward, it is ensured that the adjusting rod 206 always moves in the horizontal direction. Moreover, through the action of the arc-shaped limiting block 205, the adjusting rod 206 can drive the arc-shaped limiting block 205 to rotate when it rotates, thereby adjusting the rotation angle of the shearing blade 203.
[0026] like Figure 2 and Figure 3 As shown, in this embodiment, the hollow rotating shaft 204 is provided with a first spring 207 that is adapted to the adjusting rod 206. A pull handle 210 is movably installed inside the side toothed plate 209. A double-axis telescopic cylinder 201 is installed on the top of the moving part. Under the action of the double-axis telescopic cylinder 201, the top shearing blade 203 can be pushed upward so that it contacts the sprue of the decorative strip, so that the shearing blade 203 cuts the sprue of the decorative strip.
[0027] like Figure 4As shown, in this embodiment, the first spring 207 is connected to the adjusting rod 206 and the hollow rotating shaft 204 at both ends, and the first spring 207 is located outside the adjusting rod 206. The two side plates 202 are symmetrically installed on the top of the output end of the dual-axis telescopic cylinder 201. A T-shaped groove adapted to the pull handle 210 is opened on one side of the side toothed plate 209. The pull handle 210 is rotatably connected inside the T-shaped groove. One end of the adjusting rod 206 is connected to one side of the arc-shaped limiting block 205. The side toothed plate 209 is pulled outward by the pull handle 210, so that the adjusting rod 206 moves outward from the depth of the hollow rotating shaft 204 cavity, providing a certain pulling force for the adjusting rod 206 to move outward. When the side toothed plate 209 rotates, the pull handle 210 is not fixed inside the side toothed plate 209, ensuring that the side toothed plate 209 rotates normally.
[0028] Furthermore, both the moving part and the shearing blade 203 are conventional position adjustment methods well known to those skilled in the art, and their specific parameters can be selected according to actual needs. Manually pulling the handle 210 outwards causes the side toothed plate 209 to move, pulling it out of the side toothed ring 208 and freeing it from its constraint. The side toothed plate 209 then moves the adjusting rod 206 within the hollow rotating shaft 204. Under the action of the arc-shaped limiting block 205, the adjusting rod 206 moves stably outwards. With the cooperation of the adjusting rod 206 and the hollow rotating shaft 204, the first spring 207 is compressed and deformed, then a rotational force is applied to the side toothed plate 209. As the side toothed plate 209 rotates, the handle 21... The lever 206 rotates within the side toothed plate 209, causing the adjusting rod 206 to rotate. The adjusting rod 206, through the action of the arc-shaped limiting block 205, causes the hollow rotating shaft 204 to rotate. The hollow rotating shaft 204 then causes the shearing blade 203 to rotate on opposite sides of the two side plates 202, adjusting the angle of the shearing blade 203. After this adjustment, the force applied to the handle 210 and the side toothed plate 209 is released. Under the action of the first spring 207, the adjusting rod 206 is pushed in the opposite direction, moving to the deepest part of the hollow rotating shaft 204. The adjusting rod 206 then causes the side toothed plate 209 to move in the opposite direction, locking it in the side toothed ring 208 and restricting its rotation. This completes the angle adjustment of the shearing blade 203.
[0029] Example 2
[0030] Reference Figure 5 and Figure 6 This is the second embodiment of the present invention, which is based on the previous embodiment. The clamping mechanism 3 is located on the top of the adjusting mechanism 2. The clamping mechanism 3 includes a support frame 301 installed on the top of the moving part. A horizontal plate 302 is provided at the center of the inner surface of the support frame 301. T-shaped blocks 303 are symmetrically arranged inside the horizontal plate 302. A receiving plate 306 is installed on the top of the T-shaped blocks 303. Clamping rods 307 are symmetrically arranged on the top of the receiving plate 306.
[0031] like Figure 1 and Figure 6 As shown, in this embodiment, the top of the horizontal plate 302 is symmetrically provided with sliding grooves that are adapted to the T-shaped block 303. The T-shaped block 303 is slidably connected inside the sliding groove, and the receiving plate 306 is slidably connected to the top of the horizontal plate 302. Under the action of the sliding groove, the stability of the T-shaped block 303 during movement is ensured.
[0032] like Figure 5 and Figure 6 As shown, in this embodiment, a second spring 305 is provided on one side of the T-shaped block 303, a tapered hole is opened at the top center of the horizontal plate 302, a control panel is movably installed on one side of the support frame 301 through a hinge seat, and a baffle 304 is movably installed inside the T-shaped block 303. Under the action of the tapered hole, the tip of the waste material in the injection-molded decorative strip group is inserted into the tapered hole. Under the action of the second spring 305, the clamping rod 307 is pushed to both sides of the waste material of the decorative strip group through the T-shaped block 303, and the sprue of the decorative strip is placed horizontally.
[0033] Furthermore, both sets of clamping rods 307 are pulled outwards, and the tip of the decorative strip waste to be cut is inserted into the conical hole at the center of the horizontal plate 302. The device strip is placed on both sides of the top of the horizontal plate 302. The tension applied to the clamping rods 307 is released. Under the action of the second spring 305, the second spring 305 applies a pushing force to the T-shaped block 303 towards the conical hole, causing the T-shaped block 303 to drive the receiving plate 306 to move. The receiving plate 306 drives the two clamping rods 307 to move, so that the two clamping rods 307 abut against one side of the waste. Under the action of the two sets of symmetrical clamping rods 307, the waste connecting the decorative item is clamped.
[0034] Working principle: The device is connected to an external power supply controller using a wiring harness. Both sets of clamping rods 307 are pulled outwards. The tip of the decorative strip scrap to be cut is inserted into the conical hole at the center of the horizontal plate 302. The decorative strip is placed on both sides of the top of the horizontal plate 302. The tension applied to the clamping rods 307 is released. Under the action of the second spring 305, the second spring 305 applies a pushing force to the T-shaped block 303 towards the conical hole, causing the T-shaped block 303 to move the receiving plate 306. The receiving plate 306 then moves the two clamping rods 307, causing the two clamping rods 307 to press against one side of the scrap. The two sets of clamping rods are then positioned symmetrically. Under the action of the holding rod 307, the waste material connecting the ornament is clamped. The cutting angle of the shearing blade 203 is adjusted according to the cutting angle of the sprue of the ornament after clamping. The pull handle 210 is manually pulled outward, which drives the side toothed plate 209 to move, pulling the side toothed plate 209 out of the side toothed ring 208, so that the side toothed plate 209 is freed from the restriction of the side toothed ring 208. The side toothed plate 209 drives the adjusting rod 206 to move in the hollow rotating shaft 204. Under the action of the arc-shaped limiting block 205, the adjusting rod 206 moves stably outward. With the cooperation of the adjusting rod 206 and the hollow rotating shaft 204, the first Spring 207 is compressed and deformed, then a rotational force is applied to the side toothed plate 209. As the side toothed plate 209 rotates, the pull handle 210 rotates within it. The side toothed plate 209 drives the adjusting rod 206 to rotate. The adjusting rod 206, through the action of the arc-shaped limiting block 205, drives the hollow rotating shaft 204 to rotate. The hollow rotating shaft 204 drives the shearing blade 203 to rotate on opposite sides of the two side plates 202, adjusting the angle of the shearing blade 203. After this adjustment, the force applied to the pull handle 210 and the side toothed plate 209 is released. Under the action of the first spring 207, the adjusting rod 206 is pushed in the opposite direction. Move the adjusting rod 206 to the deepest part of the hollow rotating shaft 204. The adjusting rod 206 drives the side toothed plate 209 to move in the opposite direction, so that the side toothed plate 209 is locked in the side toothed ring 208, restricting the rotation of the side toothed plate 209, and completing the angle adjustment of the shearing blade 203. Flip the control panel on one side of the support frame 301 upward around the hinge seat to a suitable angle. Control the movement of the moving parts through the controller. Through the horizontal and vertical movement, and then control the cooperation of the double-axis telescopic cylinder 201, move the shearing blade 203 to the sprue that needs to be cut. Control the operation of the shearing blade 203 to cut the sprue of the decorative strip.
