The above four states are reciprocating, and the double-cylinder intermittent feeding mechanism 23 directly realizes the intermittent feeding of materials under the action of gravity through the cooperation of the upper and lower cylinders. This method has a very simple structure and is convenient for debugging and maintenance. Cylinders are also very cheap.

The winding function is the basic function of the tape automatic winding machine. As shown in Figure 6, the automatic winding device 3 includes a discharge roller shaft 31 for placing the tape raw material roll, and a material receiving roller linked with the positioning shaft on the automatic winding station. Roller shaft 34, the large roll of tape raw material roll passes through the unwinding roller shaft 31, releases the raw material tape, then passes through the tension control mechanism 32, the automatic deviation correction mechanism 33 in turn, and shares the tension through the receiving roller shaft 34, and automatically winds up on the station The corresponding positioning shaft is linked with the receiving roller shaft to realize the winding of the tape by the mandrel of the tape roll.

Among them, the counting sensor is installed at the discharge roller shaft 31, the discharge roller shaft 31 is installed on the transmission shaft, the transmission shaft is driven by the discharge motor, the counting sensor includes a magnet and a Hall sensor, the magnet is installed on the transmission shaft, and the Hall sensor is installed on the transmission shaft.

During the working process, the tape roll drives the transmission shaft to rotate, and the magnet also rotates together, so that the Hall sensor senses the number of turns of the discharge roller shaft, and then calculates the length of the discharged tape to realize the tape length. control. Therefore, the winding length can be precisely controlled by the rotation speed base, the speed of the discharge motor can be adjusted to achieve stepless speed regulation, and the winding speed can be manually adjusted according to the operator's proficiency.

According to the degree of automation of the tension control method, it can be divided into manual tension control, semi-automatic tension control and fully automatic tension control from low to high. The principle of manual tension control, firstly according to the detected tension, and then the operator adjusts the output torque of the motor, which is suitable for low-speed, low-precision rewinding equipment; the principle of semi-automatic tension control, first calculates the roll diameter of the current unwinding roller, Generally, the counting roller shaft instrument is used, and then the output torque of the motor is adjusted to realize the stable control of the unwinding tension. It belongs to the open-loop control mode and is suitable for medium and low speed occasions; the principle of automatic tension control, first read the tension signal through the tension sensor, Then after digital-to-analog conversion, compared with the set reference signal, the difference is calculated and amplified, and then the exciting current is adjusted to control the unwinding tension. Tension fluctuation, suitable for occasions requiring high precision. However, the cost of this fully automatic tension control technology is high. Therefore, the tension control mechanism of the weight hammer method is selected. Since the winding speed of the automatic medical tape winding machine is low, the products produced by this method of tension control meet the requirements.

Wherein, the tension control mechanism 32 includes a weight 322 provided with a tension control roller 323 and an upper limit sensor and a lower limit sensor corresponding to the upper limit and lower limit of the weight. Under the action of gravity of the weight, the tension control roller 323 will The adhesive tape is pulled down, and the weight is slidably installed on the weight guide rod 321 . The tension control mechanism in the form of a heavy hammer is used to monitor the position of the heavy hammer through the sensor. After processing by the control system, the speed of the discharge roller is controlled, and the heavy hammer is controlled between the upper and lower limits, so that the tension is controlled within a certain range.

The upper limit sensor and the lower limit sensor are connected to the tension controller, and the weight moves between the upper and lower limits. When the tension increases, the weight moves upward. If the upper limit sensor detects that the weight exceeds the upper limit, it will be processed by the controller. , and finally by increasing the speed of the discharge roller shaft, the tension is controlled within the set range; when the tension becomes smaller, the weight moves down, and if the lower limit sensor detects that the weight exceeds the lower limit, it will be processed by the controller and finally passed Reduce the speed of the discharge roller shaft to control the tension within the set range. The tension control method has simple structure, convenient debugging and maintenance, and low manufacturing cost.

During the conveying process of the tape roll from the unwinding roller 31 to the receiving roller 34, due to factors such as the installation accuracy of the parts and the stability of the equipment operation, there will be lateral deviation during the conveying process, which will affect the subsequent winding. Therefore, it is necessary to adopt an automatic deviation correction mechanism to reduce the influence of deviation.

Specifically, an automatic deviation correction mechanism 32 is provided between the tension control mechanism 33 and the discharge roller shaft 31, and the automatic deviation correction mechanism 32 includes a horizontal slide rail 333 and a screw slide table 331 slidably installed on the horizontal slide rail. The lead screw slide table is provided with a deflection correction control roller shaft 332 for the tape to pass through and a lead screw linked with the output shaft of the stepping motor, and the step motor drives the lead screw slide table to slide along the lateral slide rail to Correct lateral deviation. The automatic deviation correction mechanism 32 adopts the principle of a photoelectric deviation correction machine, and a photoelectric detection switch is provided corresponding to the positions at both ends of the horizontal direction. The position of one side is detected by the photoelectric detection switch. By picking up the position deviation signal, the position deviation signal is subjected to logical operation, and then a control signal is generated. , through the drive to control the rotation of the stepping motor, it drives the screw slide to move, so as to achieve the purpose of correcting the lateral deviation. The deviation correcting machine has the characteristics of convenient installation, good deviation correction effect, and smaller lines.

In addition, the gas-hydraulic correction mechanism can also be used. According to the principle of air pressure and hydraulic servo, the edge of the material is checked based on the air pressure sensing convection method, and the air pressure ratio difference is generated at the detector outlet. It has the characteristics of stable performance, sensitive response, convenient operation and convenient maintenance. However, compared with the above-mentioned photoelectric correction mechanism, the deviation correction mechanism is larger in mass and volume, and is inconvenient to install. Therefore, the photoelectric correction mechanism is preferably used.

The automatic cutting and bonding device 4 adopted in the present invention is to consider that the direction of motion of the cutting and adhesive tape is consistent, and there are overlapped action points in the range of action of the force, so the two functions are combined to realize on one mechanism, which has a structure The advantage of being compact.

As shown in Fig. 9, the automatic roll surplus material device 5 includes a roll surplus material roller 51, and the coil surplus material roller 51 is arranged directly below the positioning shaft corresponding to the automatic roll change station, because during the winding process, the roll surplus material roll 51 is automatically The positioning shaft corresponding to the roll changing station is also rotating, so the automatic roll surplus device does not need to be driven. Fit and compress the tape, and rotate together with the tape roll, the remaining tape roll can be finally wound on the tape roll.

In view of the fact that the installation size of the remnant roll 51 is affected by the specific thickness of the tape, the automatic remnant device is provided with a height adjustment mechanism to adjust the height.
