Description

Technical Field

[0001] This utility model belongs to the technical field of rubber strip cutting equipment, and relates to a feeding drive device for a rubber strip cutting machine. Background Technology

[0002] The feeding process in the existing rubber injection molding machine production process requires manual assistance, which involves a large investment of human resources and labor intensity, slow feeding efficiency, and safety hazards.

[0003] Patent application number CN202421676543 discloses a multi-layer synchronous feeding machine for rubber vulcanization, including a control system, a frame, and a conveyor belt. The frame is equipped with a feeding device, which includes a movable truss, two feeding mechanisms, and a synchronization mechanism. The two feeding mechanisms are movably mounted on the movable truss in an up-down structure and are driven to move synchronously by the synchronization mechanism. There is a gap between the feeding mechanisms. Each feeding mechanism includes a feeding plate, a guide rail seat, a drive unit, and a valve assembly. The synchronization mechanism includes two synchronization seats, a movable plate, and a drive assembly. Under the control of the control system, the movable truss, feeding mechanism, and synchronization mechanism can automatically feed the rubber sheet raw material from the conveyor belt into the vulcanizing machine.

[0004] The above-mentioned feeding machine still has some shortcomings: the drive unit controls the feeding action through a belt, but the specific transmission structure is not disclosed, while the traditional method of controlling the transmission wheel to drive the belt to move the feeding plate has a shorter stroke. Summary of the Invention

[0005] This utility model addresses the aforementioned problems in existing technologies by providing a feeding drive device for a rubber strip cutting machine. The technical problem to be solved by this utility model is to increase the conveying stroke of the feeding plate while ensuring the accuracy of movement.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A feeding drive device for a rubber strip cutting machine includes a feeding frame, a transmission frame, and a feeding plate. The transmission frame is horizontally slidably connected to the feeding frame and is rectangular. The feeding plate is located below the transmission frame and is horizontally slidably connected to it. Vertically arranged transmission wheels are rotatably connected to both ends of the transmission frame along the sliding direction. The two transmission wheels are connected by the same annular transmission belt. The device is characterized in that both transmission wheels are connected to the lower side of the transmission frame. One side of the transmission belt is fixed to the feeding plate, and the other side of the transmission belt is fixed to the feeding frame via a connecting plate passing upward through the transmission frame. A rack arranged along the sliding direction of the transmission frame is fixed to the upper side of the transmission frame. A vertically arranged drive gear meshing with the rack is rotatably connected to the feeding frame, and the drive gear is located directly above the transmission belt.

[0008] By setting two transmission wheels on the lower side of the transmission frame, and a rack on the upper side of the transmission frame meshing with the drive gear on the loading frame, while fixing one side of the transmission belt to the loading plate and the other side to the loading frame via a connecting plate, and positioning the drive gear directly above the transmission belt, the rotation of the drive gear drives the rack to move along its length, thereby driving the transmission frame to slide relative to the loading frame. Simultaneously, the transmission frame drives the two transmission wheels to move as a whole, causing the transmission belt to move around the transmission wheels, which in turn drives the loading plate to move. Since the two sides of the transmission belt move in opposite directions, the loading plate can move twice the unit distance relative to the loading frame when the rack moves a unit distance, increasing the stroke and response speed of the loading plate. In addition, the drive gear and transmission belt are respectively arranged on the upper and lower sides of the transmission frame, avoiding interference and allowing both to be arranged closer to the geometric center of the transmission frame, thereby reducing the off-center load on the transmission frame itself, making the movement direction of the transmission frame more stable, reducing the positional deviation of the transmission frame, and ensuring the accuracy of the operation.

[0009] In the feeding drive device of the aforementioned rubber strip cutting machine, the transmission frame is rectangular, and the two transmission wheels are rotatably connected to the opposite two side frames. This facilitates a lightweight design of the transmission frame, avoids excessive weight of the feeding device affecting transmission efficiency, and also allows the connecting plate to pass through the transmission frame upwards for easy connection with the feeding frame.

[0010] In the feeding drive device of the aforementioned rubber strip cutting machine, a support plate arranged parallel to the rack is fixed to the inner edge wall of the transmission frame. The cross-section of the support plate is L-shaped, and the rack is supported and fixed to the support plate. This facilitates the rack's arrangement close to the geometric center of the transmission frame, while the support plate provides support along the entire length of the rack, ensuring a stable rack position and preventing deformation that could affect transmission accuracy.

[0011] In the feeding drive device of the aforementioned rubber strip cutting machine, the side of the transmission belt that is fixed to the feeding plate is located horizontally between the rack and the connecting plate. Thus, the force-bearing position of the feeding plate is located between the rack and the connecting plate, while the meshing position of the rack and the drive gear, as well as the position of the upper part of the connecting plate, are all on the upper feeding frame. These three positions are arranged in a triangular configuration, making the working structure more stable.

[0012] In the feeding drive device of the aforementioned rubber strip cutting machine, a triangular reinforcing rib is fixed at the inner corner of the transmission frame. This helps to strengthen the overall strength of the transmission frame, ensuring that it is not easily deformed, thereby guaranteeing the transmission accuracy of the transmission belt and rack.

[0013] Compared with the prior art, the advantages of this utility model are as follows:

[0014] The feeding drive device of this rubber strip cutting machine is equipped with a rack on the transmission frame. When the rack moves a unit distance, the feeding plate can move twice the unit distance relative to the feeding frame, which improves the stroke and response speed of the feeding plate. In addition, the force load on the transmission frame itself is reduced as much as possible, making the movement direction of the transmission frame more stable, and taking into account both the motion accuracy and the large movement stroke of the feeding plate.

[0020] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0021] like Figure 1 As shown, the feeding drive device of this rubber strip cutting machine includes a feeding frame 1, a transmission frame 2, and a feeding plate 3. The transmission frame 2 is horizontally slidably connected to the feeding frame 1 via an existing slide rail. The transmission frame 2 is rectangular. The feeding plate 3 is located below the transmission frame 2 and is horizontally slidably connected to the transmission frame 2 via an existing slide rail. A rack 7 is fixedly provided on the upper side of the transmission frame 2 along the sliding direction of the transmission frame 2. A vertically arranged drive gear 8 that meshes with the rack 7 is rotatably connected to the feeding frame 1. The drive gear 8 is driven to rotate by an existing motor reduction assembly. A transmission belt 5 is provided on the transmission frame 2, and the drive gear 8 is located directly above the transmission belt 5.

[0022] like Figure 2 , Figure 3 As shown, vertically arranged transmission wheels 4 are rotatably connected to both ends of the transmission frame 2 along the sliding direction. The two transmission wheels 4 are connected by the same annular transmission belt 5. Both transmission wheels 4 are connected to the lower side of the transmission frame 2. One side of the transmission belt 5 is fixed to the loading plate 3, and the other side of the transmission belt 5 is fixed to the loading frame 1 through a connecting plate 6 that passes upward through the transmission frame 2.

[0023] like Figure 4 As shown, the transmission frame 2 is rectangular, with two transmission wheels 4 rotatably connected to opposite side frames. A support plate 9, parallel to the rack 7, is fixed to the inner wall of the transmission frame 2. The support plate 9 has an L-shaped cross-section, and the rack 7 is supported and fixed to this support plate 9. The side of the transmission belt 5 that is fixed to the feeding plate 3 is located horizontally between the rack 7 and the connecting plate 6. Triangular reinforcing ribs 10 are fixed at each of the three inner corners of the transmission frame 2.

[0024] When the drive gear 8 is driven to rotate, it can drive the rack 7 to move along the length direction, thereby causing the transmission frame 2, which is fixed to the rack 7, to translate relative to the loading frame 1. At the same time, the transmission frame 2 drives the two transmission wheels 4 to move as a whole, so that one side is fixed to the loading frame 1 through the connecting plate 6 and the transmission belt 5 moves around the transmission wheel 4, and then drives the loading plate 3 to move through the transmission belt 5. The two sides of the transmission belt 5 move in opposite directions, so that when the rack 7 moves a unit distance, the loading plate 3 can move twice the unit distance relative to the loading frame 1, thereby increasing the stroke of the loading plate 3.

[0025] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
