In order to optimize one process parameter, other process parameters will be deteriorated, so that the adjustment space of the production process parameters is greatly limited.

In this specification, "in one embodiment" does not mean the same embodiment, nor is it an independent or alternative embodiment that excludes other embodiments.

[0025] Embodiments

[0026] Reference Figures 1 to 4 For the embodiments of the present application, the embodiments provide a die position accurate adjustment mechanism, comprising,

[0027] The adjustment assembly 100 comprises a base 101, a motor 102 fixedly installed on the top of the base 101, an output shaft 103 fixedly installed on the output end of the motor 102, and a commutator 104 fixedly installed on the end of the output shaft 103.

[0028] The positioning assembly 200 comprises a support seat 201 arranged on the outer side of the adjustment assembly 100, and a positioning pin 202 inserted into the through hole of the support seat 201.

[0029] The power of the motor 102 is transmitted to the commutator 104 through the output shaft 103, and the positioning ring sleeve 105, the transmission shaft rod 106, the fixed sleeve 107, the coupling 108 and other components outside the commutator 104 work together to uniformly distribute and transmit power to the two synchronous shafts 109, thereby driving the four ball screw elevators 110 to operate synchronously. This transmission mode not only ensures efficient transmission of power, but also ensures the synchronization and stability of the movement of each ball screw elevator 110, meets the requirements of the equipment carrying capacity in the production process, and further guarantees the stability and reliability of the production process.

[0030] Specifically, the adjusting assembly 100 further comprises a positioning ring sleeve 105 fixedly installed outside the commutator 104, a transmission shaft rod 106 rotatably installed on one side of the positioning ring sleeve 105, a fixed sleeve 107 fixedly installed on the other side of the positioning ring sleeve 105, a coupling 108 fixedly installed outside the fixed sleeve 107, a synchronous shaft 109 fixedly installed outside the coupling 108, and a ball screw elevator 110 rotatably installed at the end of the synchronous shaft 109. The number of synchronous shafts 109 is two, and they are evenly distributed outside the commutator 104. The number of commutators 104 is two, and they are evenly distributed at both ends of the transmission shaft rod 106.

[0031] The ball screw elevator 110 realizes high-precision reciprocating lifting function, and its high-precision characteristics ensure that the distance between the die head and the shaping roller can be accurately adjusted, avoiding the trouble of frequently adjusting and correcting the lifting height of the screw rod at different working positions. The motor 102 transmits power to the commutator 104 through the output shaft 103, and then drives the ball screw elevator 110 to work through a series of transmission components. The application of the brake motor 102 makes the mechanism realize online accurate adjustment at any position. The operator does not need to perform complex manual operation or frequent equipment calibration. It can easily realize accurate adjustment of the die head position through the control system, greatly reducing the labor intensity of workers and improving production efficiency and product quality.

[0032] Further, the positioning assembly 200 further comprises a vertical rod 203 sleeved in the inner cavity of the support seat 201, and a sleeve 204 fixedly installed on the top of the support seat 201. The bottom of the vertical rod 203 is adaptively connected with the top of the ball screw elevator 110, and the sleeve 204 can cooperate with the vertical rod 203 to adjust the height.

[0033] During the adjustment process, the vertical rod 203 adjusts the height in the inner cavity of the support seat 201 in cooperation with the sleeve 204, and the bottom of the vertical rod 203 is adaptively connected with the top of the ball screw elevator 110, which ensures the stability and accuracy of the entire lifting process.

[0034] Preferably, the number of couplings 108 is nine, and the transmission shaft rod 106 is connected with the synchronous shaft 109 through the couplings 108, and the couplings 108 can realize four-point synchronous lifting with the transmission shaft rod 106 and the synchronous shaft 109.

[0035] The four ball screw elevators 110 can realize lifting of the cooling roller and the shaping roller installed in cooperation, and the unique design can not change the wrap angle between the film and the roller when adjusting the distance parameter between the die head and the shaping roller, thereby effectively avoiding the problem that optimization of one process parameter leads to deterioration of other key process parameters, the wrap angle of the film on the roller remains stable, the cooling and forming effect of the film at the key position is not affected, and the production efficiency and economic benefits are improved.

[0036] It should be noted that the specific model of the motor 102 is YEJ3-132S-4 type with a brake variable frequency motor, and the specific parameters are: rated power: 5.5 kW; rated voltage: 380 V; rated current: 11.6 A; rated speed: 1440 r / min; protection level: IP55.

[0037] In use, the motor 102 is started, power is transmitted to the commutator 104 through the output shaft 103, the power is distributed and transmitted to the two synchronous shafts 109 through the positioning ring sleeve 105, the transmission shaft rod 106, the fixed sleeve 107 and the couplings 108, and then the ball screw elevator 110 is driven to operate, the ball screw elevator 110 drives the vertical rod 203 connected therewith to lift in the inner cavity of the support seat 201, the sleeve 204 adjusts the height in cooperation with the vertical rod 203, and the positioning pin 202 positions the support seat 201, and the precise adjustment of the die head position is realized through the cooperative operation of the components.

[0038] In summary, the cooperative matching of the adjustment assembly 100 and the positioning assembly 200 brings many significant advantages. The motor 102 transmits power to the ball screw elevator 110 through the output shaft 103, the commutator 104 and other components, and the reciprocating lifting precision is high due to the use of the ball screw elevator 110; the brake variable frequency motor 102 can realize online precise adjustment at any position, and the labor intensity of workers is reduced. At the same time, the two synchronous shafts 109 realize four-point synchronous lifting in cooperation with the nine couplings 108, and the four ball screw elevators 110 work cooperatively to make the mechanical efficiency high, can lift larger load, can lift the cooling roller and the shaping roller together, can not only improve the distance parameter between the die head and the shaping roller, but also does not affect the wrap angle of the film on the roller and the cooling and forming effect of the film at the key position, so that high-speed production is possible, and economic benefits are improved.
