Abstract
Description
Technical Field
[0001] This application relates to the field of rubber ring manufacturing, and in particular to a ring-pinching device. Background Technology
[0002] With the development of rubber vulcanization technology, the requirements for the functionality, process efficiency, and quality control of vulcanized products are becoming increasingly stringent. In particular, higher demands are being placed on aspects such as the seams during mold closing, the uniformity of the product shape after vulcanization, waste reduction, and more uniform product density and cross-linking. Large-sized circular sealing rings and gaskets require seamlessness, high roundness, uniform vulcanization to prevent leakage, and reduced flow defects. Therefore, some vulcanization molds with circular cavities require the installation of rubber material of approximately the same shape inside the mold when making the circular rings. Thus, a ring-pinching device is needed in rubber loading and unloading integrated machines to pinch the cut rubber strips into approximately circular rings, and then insert each ring into the corresponding circular cavity of the vulcanizing machine mold for vulcanization. Utility Model Content
[0003] In order to squeeze a rubber strip, this application provides a squeezing device.
[0004] This application provides a pinching device, which adopts the following technical solution:
[0005] A pinching device includes a second frame, a first mounting bracket, a second mounting bracket, and a first rotating disk. The first mounting bracket is disposed on the second frame, and the second mounting bracket is disposed on one side of the first mounting bracket. The first rotating disk is rotatably connected to the second frame. The second frame is provided with a fourth driving member for driving the first rotating disk to rotate. The first rotating disk is provided with a first pressure rod and a second pressure rod. The first pressure rod is disposed on the first rotating disk, and the first rotating disk is provided with a first driving member for driving the pressure end of the first pressure rod to move closer to the peripheral wall of the first rotating disk. The second pressure rod is disposed on the second mounting bracket, and the second mounting bracket is provided with a second driving member forcing the second pressure rod to move closer to the first rotating disk.
[0006] By adopting the above technical solution, the rubber strip is placed on one side of the first rotating disk, and then one end of the rubber strip is pressed by the first driving component. Then the first rotating disk rotates, which drives the rubber strip to bend. After rotating once, the second pressure rod presses the other end of the rubber strip, so that the two ends of the rubber strip are connected to each other to form a circle, so that the rubber ring can be placed in the corresponding circular cavity of the vulcanizing machine mold for vulcanization.
[0007] Optionally, the second mounting bracket is provided with a first connecting plate that slides in a direction toward the first rotating disk, and the second mounting bracket is provided with a third driving member that drives the first connecting plate to move toward the first rotating disk; the second mounting bracket is provided with a limiting plate that is rotatably connected to the first connecting plate.
[0008] By adopting the above technical solution, the middle part of the rubber strip is limited by the limiting plate, so that the rubber strip can be circular around the first rotating plate. The limiting plate is rotatably connected to the first connecting plate. During the limiting process, the limiting plate can rotate, thereby reducing the friction between the limiting plate and the rubber strip during the limiting process.
[0009] Optionally, the second frame is provided with a mounting plate, which is slidably connected to the second frame along the length direction of the second frame. The second frame is provided with a first driving assembly for driving the mounting plate to slide, and the first mounting bracket is disposed on the mounting plate.
[0010] By adopting the above technical solution, the first driving component can drive the mounting plate to move, thereby driving the entire first rotating disk to move.
[0011] Optionally, the upper end of the first mounting bracket is provided with a rotating rod, which rotatably passes through the mounting plate, and the mounting plate is provided with a second driving assembly for driving the rotating rod to rotate.
[0012] By adopting the above technical solution, the first mounting bracket is connected to the mounting plate through a rotating rod, which facilitates driving the first rotating disk to rotate.
[0013] Optionally, the second drive assembly includes a linear drive, a gear, and a rack. The linear drive is mounted on a mounting plate, the gear is coaxially disposed on a rotating rod, and the rack is disposed on a moving block of the linear drive, with the rack meshing with the gear.
[0014] By adopting the above technical solution, the linear drive component drives the rack to move, thereby driving the gear to rotate, and in turn driving the first mounting bracket to rotate.
[0015] Optionally, a first frame is provided below the second frame, a conveyor belt is provided on the first frame, the first rotating disk is located above the conveyor belt, and there is a gap between the upper surface of the first rotating disk and the upper surface of the conveyor belt.
[0016] By adopting the above technical solution, the mounting plate is moved by the first drive component, which makes it easier to make rubber rings at different positions of the transmission belt.
[0017] Optionally, the first rotating disk is slidably connected to a second rotating disk in the vertical direction, and the second rotating disk and the first rotating disk are coaxially arranged.
[0018] By adopting the above technical solution, when it is necessary to make a rubber ring, the second rotating disk moves downward and abuts against the conveyor belt. Then, the first pressure rod presses the end of the rubber strip against the outer peripheral wall of the second rotating disk. When the second rotating disk rotates, it can drive the rubber strip to form a circle. When it is necessary to move the first rotating disk and the second rotating disk, the second rotating disk is driven to move upward, so that the second rotating disk disengages from the abutment with the transmission belt.
[0019] Optionally, the second mounting bracket is slidably connected to a third mounting bracket in the vertical direction, and the second pressure rod and the limiting plate are both disposed on the third mounting bracket.
[0020] By adopting the above technical solution, the second pressure rod and the limiting plate can move up and down, thus facilitating their movement along with the mounting plate.
[0021] A rubber feeding and unloading integrated machine includes a frame, a feeding mechanism, a cutting mechanism, a transfer mechanism, a loading mechanism, and a kneading device. The feeding mechanism, cutting mechanism, loading mechanism, and transfer mechanism are all fixedly installed on the frame. The feeding mechanism is used to transport rubber sheets to the cutting mechanism for cutting. The kneading device is fixedly installed on the frame. The transfer mechanism transports the rubber strips to the conveyor belt of the kneading device for kneading. The loading mechanism transports the kneaded rubber rings into the vulcanizing mold.
[0022] In summary, this application includes at least one of the following beneficial technical effects:
[0023] 1. Place the rubber strip on one side of the first rotating disk, and then press one end of the rubber strip with the first driving component. Then the first rotating disk rotates, which drives the rubber strip to bend. After rotating once, the second pressure rod presses the other end of the rubber strip, so that the two ends of the rubber strip are connected to each other to form a circle, so that the rubber ring can be placed in the corresponding circular cavity of the vulcanizing machine mold for vulcanization.
[0024] 2. When it is necessary to make a rubber ring, the second rotating disk moves downward and abuts against the conveyor belt. Then the first pressure rod presses the end of the rubber strip against the outer peripheral wall of the second rotating disk. When the second rotating disk rotates, it can drive the rubber strip to form a circle. When it is necessary to move the first rotating disk and the second rotating disk, the second rotating disk is driven to move upward, so that the second rotating disk disengages from the abutment of the conveyor belt.
