Description

[Technical field]

[0001] The invention relates to the field of cutting devices, in particular to a rubber ring cutting device. [Background technology]

[0002] At present, rubber products are widely used in social life, including a rubber ring, which is often cut from a ring-shaped rubber sleeve.

[0003] The existing rubber rings are mostly made of translucent rubber materials. In the production process of rubber rings, the cutting of rubber sleeves is often completed on a workbench. The operator first sets the rubber sleeve on a fixed block fixed on the workbench. The fixed block is a cylindrical block and has grooves on its arc-shaped outer wall around the rotating block. The grooves are evenly spaced along the axial direction of the rotating block. The spacing between the two grooves is the thickness of the rubber ring of the vehicle to be produced. The inner wall of the rubber sleeve is fitted with the outer wall of the rotating block, and the rubber sleeve is cut around the fixed block by aligning the blade with the groove. For example, patent application number: CN202020017091.0 discloses a CNC cutting device for rubber ring production. When producing rubber rings, the operator first sets the rubber sleeve on the rotating block, and the inner wall of the rubber sleeve is pressed against the rotating block. Then the operator starts the cutting device, and the rotating drive member drives the rotating block to rotate. The operator drives the base to slide through the first driving component to align the cutter with the rotating rubber sleeve, and then drives the top seat to slide back and forth through the second driving component to achieve a cut on the rubber sleeve. Subsequently, the base slides again under the drive of the first driving component, and the top seat slides back and forth under the drive of the second driving component to achieve a second cut on the rubber sleeve. After repeating this process many times, the rubber sleeve can be divided into multiple rubber rings to complete the production of the rubber ring. However, in order to avoid the movement of the rubber sleeve during cutting, this type of cutting device is designed with a rotating block having a diameter larger than the inner diameter of the rubber sleeve to ensure that the rubber sleeve will not shift when it is cut on the rotating block to ensure the quality of the rubber ring after cutting. However, the diameter of this type of rotating block is larger than the inner diameter of the rubber sleeve, which makes it inconvenient for the rubber sleeve to be put on the rotating block, and it is very inconvenient to remove the cut rubber ring.

[0004] The present invention is proposed in view of the deficiencies in the prior art. [Summary of the invention]

[0005] The purpose of the present invention is to overcome the above-mentioned disadvantages of the prior art and provide a rubber ring cutting device.

[0006] The present invention can be implemented by the following technical solutions:

[0007] The present invention discloses a rubber ring cutting device, comprising a frame, a screw rod and a sliding rod are horizontally arranged on the frame, the screw rod is driven to rotate by a horizontal motor, a slide table is also arranged on the frame, the screw rod passes through the slide table and is threadedly connected to the slide table, the sliding rod passes through the slide table and is slidably connected to the slide table, a vertical plate is fixed on the slide table, a longitudinal motor is fixed on the vertical plate, a screw rod is fixed on the output end of the longitudinal motor, a slide plate is also arranged on one side of the vertical plate, a threaded pipe is fixed on the slide plate, the screw rod is threadedly connected to the threaded pipe, a cutter is also arranged on the slide plate, the A rotating tube is also provided on the frame, and the rotating tube is driven to rotate by a rotating motor.

Put the rubber sleeve to be cut on the outside of the rotating tube. After the rubber sleeve is placed, the cylinder is started, the piston rod on the cylinder is extended, the push rod moves, and the turntable moves with the push rod. Since the upper limit shaft of the turntable is connected to the positioning shaft through the push plate, and one end of the push plate is rotatably connected to the positioning shaft, and the other end of the push plate is rotatably connected to the limit shaft, when the turntable moves, the support plate moves away from the rotating tube, and each support plate moves away from the rotating tube. Each support plate props up the rubber sleeve in the rubber sleeve and tightens it. After the rubber sleeve is fixed, the lead screw is driven to rotate by the transverse motor. Since the lead screw is threadedly connected to the slide table, when the lead screw rotates, the slide table moves transversely, and the cutter moves transversely with the slide table. After the cutter reaches the cutting position facing the rubber sleeve, the transverse motor stops, and the longitudinal motor starts, and the longitudinal motor drives the screw to rotate. Since the screw is rotatably connected to the threaded tube on the slide plate, when the screw rotates, the slide plate moves toward the rubber sleeve. After the cutter contacts the rubber sleeve, the rotating tube is driven to rotate by the rotating motor, the support plate rotates with the rotating tube, and the rubber sleeve rotates with the rotating tube. After the cutter cuts the rubber sleeve, the longitudinal motor drives the screw to rotate in the opposite direction, and the cutter moves away from the rubber sleeve. The transverse motor drives the screw to rotate again, the slide moves again, and the cutter moves with the slide to the next cutting position on the rubber sleeve again. The rubber sleeve is cut by the cutter again. The cycle operation is carried out. After the rubber sleeve is cut into multiple rubber rings by the cutter, the cutter returns to the initial position, the cylinder is started again, the piston rod on the cylinder is shortened, the push rod moves, and the support plate moves close to the rotating tube to remove the cut rubber ring. When the rubber sleeve is fixed, the rubber sleeve is fixed by the support plate away from the rotating tube. When the rubber ring is removed, the support plate moves close to the rotating tube. The rubber ring is not tightly fixed on the support plate, and it is very convenient to remove the rubber ring.

[0008] Preferably, a plurality of support rods are fixed on the vertical plate, and the support rods pass through the slide plate and are slidably connected to the slide plate.

[0009] Preferably, a positioning block is fixed on the slide plate, the cutter is fixed on the slider, a positioning rod is also fixed on the slider, the positioning rod passes through the positioning block and is slidably connected to the positioning block, a limiting block is also fixed at the end of the positioning rod, and a spring is also fixed between the positioning block and the slider. The cutter on the slider is pushed by the spring to cut the rubber sleeve, and the cutter blade can reach the gap between adjacent support plates, so that the cutter can completely cut off the rubber sleeve.

[0010] Preferably, a driven wheel is fixed on the rotating tube, a driving wheel is fixed on the output end of the rotating motor, and the driving wheel is connected to the driven wheel via a synchronous belt.

[0011] Compared with the prior art, the present invention has the following advantages:

When the rubber ring is removed, the support plate is moved close to the rotating tube. The rubber ring is not tightened and fixed on the support plate, and it is very convenient to remove the rubber ring.
