Description

Long strip rubber cutting machine

technical field

The utility model relates to a rubber production equipment, in particular to a strip-shaped rubber cutting machine used for cutting rubber materials in batches in the rubber production process. the

Background technique

As we all know, in the field of rubber manufacturing, there is a rubber molding method called injection vulcanization molding. In this molding method, the refined rubber material needs to be cut into long strips in advance, and then the long strip rubber material is injected into the molding mold by heating and extrusion for vulcanization and molding. This injection-type vulcanization molding method can reduce defects and air bubbles on rubber products and improve the yield rate. the

At present, in the rubber production line, the cutting operation of the rubber material is done manually, and the cutting process requires the use of some specific knives. These knives can be general scissors or guillotines, etc., or they can be specially designed for specific products. of knives. However, these knives need to be manipulated by manpower. Therefore, the width of the cut strips of rubber is often different in size, which will affect the injection link in the subsequent injection vulcanization molding, and this cutting method requires a lot of time. A large amount of labor not only increases the manufacturing cost, but also affects the production efficiency. the

Utility model content

The problem to be solved by the utility model is to provide a strip-shaped rubber cutting machine, which can ensure the same width of the strip-shaped rubber material after cutting, and almost does not need to consume labor, which can reduce the manufacturing cost. Increase productivity. the

In order to solve the above problems, the following solutions are adopted:

The strip-shaped rubber cutting machine of the utility model is characterized in that it includes a frame, and the upper part of the frame has blade shafts and rollers arranged in parallel from top to bottom in turn. Rotate shape is fixed on the frame. A plurality of circular blades with outer cutting edges are evenly distributed on the blade shaft, the circular blades are coaxial with the blade shaft, and the circular blades and the roller are in virtual contact state. Both ends of the rollers are protruded outside the frame, and a gear is fixed on one protruding end, and a driven wheel is fixed on the other protruding end. The corresponding end of the blade shaft and the roller gear end also protrudes outside the frame, and a gear is fixed on this end of the blade shaft, and the gear of the blade shaft and the gear of the roller mesh together. There is a motor below the rollers on the frame, and the output end of the motor extends out of the frame and corresponds to the end of the roller driven wheel. The output end of the motor is fixed with a driving wheel, and the motor driving wheel and the roller driven wheel There is a linkage between them.

The further improvement scheme of the present utility model is that there are square holes on the frame corresponding to both ends of the blade shaft, and there are screw holes on the corresponding frame above the square hole, and screw handles are arranged in the screw holes. The lower end stretches in the square hole. Both ends of the blade shaft are provided with guide blocks, and the guide blocks cooperate with the square holes of the frame in an up-and-down sliding manner, and the upper ends of the guide blocks are connected with the lower ends of the screw handles. In this way, the height of the blade shaft can be adjusted by the screw handle, reducing damage to the circular blade, blade shaft, roller or rubber due to excessive extrusion. the

Wherein, the upper part of the guide block has a transverse hole, and the corresponding guide block above the transverse hole has a through hole, and the diameter of the through hole is equal to the outer diameter of the stud on the screw handle. The lower end of the screw handle is in an inverted T shape, which is assembled on the guide block through the through hole and the transverse hole of the guide block. Both sides of the guide block have longitudinal grooves, and both sides of the frame square hole have longitudinal bosses, and the grooves of the guide block are matched with the bosses of the frame square hole. the

Adopting the above scheme has the following advantages:

Because the upper part of the frame of the long strip rubber cutting machine of the utility model has a blade shaft and a roller shaft sequentially from top to bottom, a motor is arranged below the roller shaft, and a plurality of circular blades with outer blades are evenly distributed on the blade shaft. , and the circular blade is in virtual contact with the roller, one end of the blade shaft is connected with one end of the roller through a gear, and the driven wheel at the other end of the roller is linked with the driving wheel of the motor. Therefore, just turn on the power of the motor, the driving wheel can drive the roller to rotate, and further drive the blade shaft to rotate, and the rotation direction of the roller and the blade shaft is opposite. The opposite rotating side of the blade shaft is sent between the two shafts. While the two shafts are rotating, not only the circular blade on the blade shaft can be used to carry out the cutting operation, but also the opposite rotation of the two shafts can drive the rubber material to move laterally. The continuous cutting operation can be realized, and the whole cutting operation hardly needs to consume labor force, which reduces the manufacturing cost and improves the production efficiency. In addition, the width of the long strips of rubber cut out by this cutting machine is completely determined by the distance between the circular blades. By pre-measurement and fixing the circular blades, it can be ensured that the long strips of rubber after cutting are all of the same width. .
