[0002] Related technology (Publication No. CN220826212U) discloses a molding and trimming device for rubber production. The device comprises a base. A drive motor is fixedly connected to the center of the base's upper side. A second support plate is fixedly connected to the motor's output terminal. Two movable plates are slidably connected to the upper surface of the second support plate. A second threaded rod is fixedly connected to the center of the two movable plates. A second rotary disc is threadedly connected to the outer side of the second threaded rod. A trimming assembly is fixedly connected to the center of the base's inner side.

[0003] In the process of implementing the above embodiments, it was found that there are at least the following problems in the related art:

[0004] This rubber production molding and trimming device can support the rubber by moving two movable plates toward or away from each other along the upper sidewall of the second support plate, depending on the size of the rubber. However, manually rotating the second rotating disk during the rubber fixation process is laborious. Furthermore, to ensure the rubber is securely fixed, the second rotating shaft must continue to rotate after the second rotating disk contacts the rubber surface, which can easily cause wear and damage to the rubber surface.

[0017] The rubber trimming device provided by the embodiments of the present disclosure can achieve the following technical effects:

[0018] The presently disclosed embodiments provide a rubber trimming device comprising a support frame, a first linear slide, a profile plate, an electric push rod, a first clamping plate, a second clamping plate, a trimming blade, a second linear slide, a first drive member, and a second drive member. During use, the electric push rod is controlled to move the first clamping plate along the height of the support frame until it contacts a rubber member placed on the first clamping plate, thereby clamping the rubber member to be trimmed. Manual operation is unnecessary, making operation convenient. Furthermore, during the clamping process, relative movement between the rubber member and the first and second clamping plates does not occur, thereby preventing wear and damage to the rubber member's surface. When the clamped rubber member is circular, the first linear slide is controlled to move the profile plate along the length of the support frame, ultimately moving the rubber member until its edge contacts the trimming blade. At this point, the first drive member is controlled to rotate the shaft, thereby rotating the second clamping plate. Because the first clamping plate and the movable end of the electric push rod are rotatable relative to each other, friction causes the rubber member to rotate, thereby completing the trimming process on all sides. When the clamped rubber piece is square, the first linear slide is controlled to align the edge of the rubber piece with the trimming blade. Then, the second linear slide is controlled to move the second drive member along the width of the support frame. This ultimately drives the trimming blade along the width of the support frame, completing the trimming of a single edge of the rubber piece. At this point, the first drive member is controlled to align the remaining edges of the rubber piece with the trimming blade in sequence, completing the trimming of the entire edge. Furthermore, the second drive member is controlled to deflect the trimming blade, thereby adjusting the angle of the trimming blade to facilitate trimming the upper and lower edges of the rubber piece.

[0035] Combine Figures 1 to 4As shown, an embodiment of the present disclosure provides a rubber trimming device, comprising a support frame 1, a first linear slide 2, a profile plate 3, an electric push rod 4, a first clamping plate 5, a second clamping plate 6, a trimming knife 7, a second linear slide 8, a first driving member and a second driving member. The support frame 1 is used to abut against the ground or a tabletop, thereby supporting the entire device. The first linear slide 2 is installed on the top surface of the support frame 1 along the length direction of the support frame 1, and is used to realize the function of moving along the length direction of the support frame 1. The profile plate 3 is installed on the movable end of the first linear slide 2, and moves along the length direction of the support frame 1 under the drive of the first linear slide 2. The electric push rod 4 is installed on the top wall of the profile plate 3 along the height direction of the support frame 1, and the movable end of the electric push rod 4 faces the bottom wall of the profile plate 3, and is used to realize the function of moving along the height direction of the support frame 1. The first clamping plate 5 is rotatably mounted on the rotating end of the electric push rod 4 and is located on the inner side of the shaped plate 3. It can rotate relative to the electric push rod 4 and, driven by the electric push rod 4, move toward the bottom wall of the shaped plate 3 to clamp one side of the rubber part. The second clamping plate 6 is located on the inner side of the shaped plate 3, below the first clamping plate 5 along the height direction of the support frame 1. The plane where the second clamping plate 6 is located is parallel to the plane where the first clamping plate 5 is located, and is used to clamp the other side of the rubber. The trimming knife 7 is located on the side of the first clamping plate 5 and the second clamping plate 6, and is used to trim the edge of the rubber part. The second linear slide 8 is installed on the top surface of the support frame 1 along the width direction of the support frame 1, and is used to move along the width direction of the support frame 1. The first driving member is installed between the second clamping plate 6 and the shaped plate 3, and is used to drive the second clamping plate 6 to rotate, thereby driving the rubber part to rotate. The second driving member is installed between the second linear slide 8 and the trimming knife 7, and is used to drive the trimming knife 7 to deflect so as to adjust the angle of the trimming knife 7. Driven by the electric push rod 4, the first clamping plate 5 can be fitted with the second clamping plate 6 to clamp the rectangular rubber member or the circular rubber member between the first clamping plate 5 and the second clamping plate 6.

[0036] A rubber trimming device provided by an embodiment of the present disclosure controls the operation of the electric push rod 4, which can drive the first clamping plate 5 to move along the height direction of the support frame 1 until it abuts against the rubber part placed on the first clamping plate 5, jointly clamping the rubber part to be trimmed. There is no need for manual operation by the user, and the operation is convenient. Moreover, during the clamping process, there is no relative movement between the rubber part and the first clamping plate 5 and the second clamping plate 6, thus avoiding wear and damage to the surface of the rubber part. When the clamped rubber part is circular, controlling the operation of the first linear slide 2 can drive the U-shaped plate 3 along the length direction of the support frame 1, and finally drive the rubber part to move until its edge abuts against the trimming knife 7. At this time, controlling the operation of the first driving member can make the rotating shaft 11 perform a rotational movement, and then drive the second clamping plate 6 to perform a rotational movement. Since the first clamping plate 5 and the moving end of the electric push rod 4 can rotate relative to each other, under the action of friction, the rubber part can rotate, thus completing the trimming work around the perimeter. When the clamped rubber part is square, after controlling the operation of the first linear slide 2 to make the edge of the rubber part abut against the trimming knife 7, controlling the operation of the second linear slide 8 can drive the second driving member to move along the width direction of the support frame 1. Finally, it drives the trimming knife 7 to move along the width direction of the support frame 1, thus completing the trimming work of a single edge of the rubber part. At this time, controlling the operation of the first driving member can make the remaining edges of the rubber part face the trimming knife 7 in sequence, thus completing the trimming work of the entire edge. Moreover, controlling the second driving member can drive the trimming knife 7 to deflect, thereby adjusting the angle of the trimming knife 7 to facilitate trimming the upper and lower edges of the rubber part respectively.

The rotating shaft 11 is rotatably installed on the first mounting plate 10 along the height direction of the support frame 1 for supporting and installing the second clamping plate 6. The second clamping plate 6 is installed at the top of the rotating shaft 11 and performs a rotational movement under the drive of the rotating shaft 11. Among them, the rotating shaft 11 can be controlled to rotate to drive the second clamping plate 6 to perform a rotational movement.

[0038] In an embodiment of the present disclosure, the first driving member includes a support rod 9, a first mounting plate 10 and a rotating shaft 11. During use, under the drive of an external force, the rotating shaft 11 can perform a rotational movement, and then drive the second clamping plate 6 to perform a rotational movement.
