Description

Import relaxation device of tranform axis at tube transformen

The present invention relates to a molding machine for molding a cylindrical tube (product) with a tube fabric (film), and more specifically, one end is fixed by the fixing device of the molding machine, the other end is the front and rear end shaft of the molding shaft is inserted into the cutting portion Ultrasonic wave and high frequency to join the joint by high frequency and sonicator, the guide step of guiding the tube fabric to the guide in the shear shaft part and the joint alignment step of aligning the joint of the guide tube fabric by roller The pinch roller which rotates the cylindrical tube bonded in one direction through the high frequency and ultrasonic heat bonding step as well as preventing the micro shock from occurring at the shear shaft part at all when the thermal bonding step is performed. Reciprocating operation is driven by roller holding step that guides through and driving of stationary motor from below When a cylindrical tube (product) is provided through a narrowing movement step and a cutting step to narrow the tube to the cutting part through a narrowing zone, the minute impact occurring at the rear short shaft portion does not interfere with the shear shaft at all. The front and rear end shafts allow the fabric of the tube guided by the guide to be moved to the cutting section along the forming axis by the joint aligning roller and the pincer that reciprocates through the pinching roller in the ultrasonic and high frequency thermal jointer. Absorption from the loosening part of the molding shaft connected with the magnet by the small impact caused by the magnets having a very strong magnetic force between the parts, without affecting the tube that is molded and transported around the molding shaft in a cylindrical shape. Of the circular seam by high frequency and ultrasonic heat In the tube forming machine of the constitution which completely eliminates defects of the seam (fine gaps caused by the bent portion) and the defective state of the cutting state by precisely cutting the tube moved to the cutting part by interlocking with the bonding area and the narrowing area. It relates to an impact relaxation device.

As is well known, a molding machine for forming a cylindrical tube into a tube fabric guides the tube fabric to a guide port, presses the seam, presses the roller, undergoes a joining process by high frequency and ultrasonic heat, and is sandwiched by a pincer that reciprocates in the pincer roller. After moving to the furnace cutting unit and cutting to provide a tube product, the molding shaft is installed in the molding machine such that one end is fixed to the guide portion and the other end is guided to the cutting portion is composed of the whole molding shaft integrally.

Therefore, it is difficult to identify by the naked eye when the joining work by high frequency or ultrasonic heat is working toward the joining surface of the molding shaft. However, very small impacts appear on the whole molding shaft. In addition, the tube of the forming shaft through the pinch roller is pinched to the pinch is carried a defect that does not accurately cut the cutting state.

Furthermore, the narrowing zone is formed between the narrowing roller and the cutting portion by reciprocating operation of the stationary motor installed downward, so that the impact of the tube is formed until the fabric of the tube is moved to the cutting portion through the guide of the forming shaft. The problem of whether the shaft is rolled exactly in the cylindrical direction has also been greatly influenced, and therefore, additional work has been required to re-examine the joining and cutting conditions of the molded tube.

Technical challenge

The present invention is a tube molding machine for forming a cylindrical tube with a tube fabric (film), the end of the tube is formed so that the joint operation of the joint at the joint surface by high frequency and ultrasonic heat through the guide port and the joint alignment roller of the molding machine The front end shaft of the shaping shaft fixed by the fastener is configured up to the rear end of the joint surface where the joint is formed. The front end portion of the rear end shaft portion for moving-cutting the cylindrically shaped cylindrical tube to the cutting portion is connected to the magnet interposed with the rear end portion of the front shaft portion, and is formed in a state in which the forming shaft is dualized. On the contrary, it does not affect (interfere) the wealth When the impact does not affect (interference) the shear shaft part, it relaxes each shock so that the tube fabric moves along the molding axis without any influence. As the tube is formed on the forming shaft by the earth, it contracts while moving to the cutting part, and when it is released from the pincer, it is expanded again and the pinching rod and the tube are continuously pinched and moved to the cutting part. In order to be able to accurately perform the cutting operation in, the purpose of the tube forming operation is to be made with the defective rate of the cut tube product is removed.

Technical solution

The present invention in order to solve the conventional problems as described above and to implement a remarkable effect to achieve the object in the molding machine for forming a cylindrical tube with a tube fabric, the one end is fixed by a fastener and the other end is inserted into the cutting part by dualizing It consists of a front shaft portion and a rear end shaft portion, between the rear end portion of the front shaft portion and the rear end shaft portion of the joint between the guide step and the joint of the tube fabric guided to the shear shaft portion through a magnet having a very strong magnetic force through the roller In order to prevent the minute impact from the ultrasonic and high frequency thermal bonding step that joins the joint with the high frequency and the ultrasonic wave, it is blocked at the loosened part through the magnet so as not to affect the rear short axis. The roller clamping step that guides the clamping roller and guides it to the clamping zone. The pinching rod, which is spring-sensitized on the rear end shaft by the screw shaft rotating forward and backward on the motor, is pinched into the pinching strip like a tube and moved to the cutting section. When the pinch is released, the pinching rod returns to its original position due to the spring force. The pincer strip also moves to the seat where the pinching rod recovered by the reverse rotation of the screw shaft can be pinched again, and pinches the pinching pin again so that the minute impact generated during the cutting step is connected to the rear end of the front shaft by a magnet at the tip of the rear shaft. By forming the shaping shaft through the forming shaft through a magnet having strong magnetic force between the shaping shaft connected to the shear shaft portion and the rear short shaft portion by being blocked by the relaxation part so as not to affect (interference) the shear shaft part at all. The front and rear ends of the cylindrical tube to be formed without affecting at all Fine shock occurring in features a molded shaft impact relaxation apparatus in the tube forming machine is to be established the bonding properties of the tube seam, and provides the accuracy of the cut state by a cutting portion in accordance with the blocked slack.

Favorable effect

The present invention is to dualize the forming axis of the molding machine to guide the tube fabric and the joint alignment step and the microscopic impact of the shear shaft caused by the bonding step by the high frequency and ultrasonic heat through the magnet at the rear end of the shear shaft portion of the rear end shaft portion The tube is cut to the cutting part by a roller clamping step for clamping the roller at the rear shaft and a clamping zone for reciprocating operation. The fine impact that occurs during the cutting step to transfer feed is also blocked at the loosening part so as not to affect (interference) of the shear shaft, thereby moving the tube by the narrow joint as well as the circular seam of the tube being formed by the forming shaft. The effect is to provide a tube with precise operation and very precise cutting conditions.
