Description

Technical field:

[0001] The present invention relates to the technical field of bottom-turning rod devices, and in particular to a bottom-turning rod adjusting device. Background technology:

[0002] The bottom turning device is usually composed of several bottom turning components installed on the bottom turning rod. When the paper bag is rolled into a tube, the bottom turning device performs the bottom turning operation, separates the bottom of the paper bag from top to bottom and flattens it to facilitate the subsequent weaving process.

[0003] The existing bottom lever adjustment device is to install a support rod in the operating area, and use the support rod to support the bottom lever for debugging and maintenance, which is inconvenient to use; and if the support is not in place, it is easy to slip and fall, which is unsafe. Summary of the invention:

[0004] In view of the above problems, the present invention proposes a bottom lever adjustment device which is easy to use, highly safe and reliable, and has a simple structure.

[0005] The present invention is achieved through the following technical solutions: a bottom-turning rod adjustment device, comprising a fixed support, a positioning support, a pull pin shaft, an actuator bracket, an actuator fixed shaft and a number of bottom-turning actuator assemblies detachably connected to the actuator fixed shaft, the positioning support being arranged on the fixed support, the positioning support having a positioning connection portion for connecting the actuator fixed shaft and adjusting the angle of the actuator fixed shaft, the positioning connection portion having an arc edge, one end of the actuator fixed shaft being hinged to the positioning connection portion through a pin shaft and being able to rotate around the pin shaft, and the other end being able to be mounted on the actuator bracket in a horizontal position.

[0006] In order to conveniently realize the adjustment and support and fixing functions of the angle of the actuator fixed shaft, the actuator fixed shaft is a hollow tubular structure, the pull pin shaft is arranged in the actuator fixed shaft through a spring, and a number of positioning holes are opened at equal angles on the arc edge of the positioning connection part. A handle is provided at the end of the pull pin shaft away from the positioning support. By stretching or releasing the handle and cooperating with the spring, the pull pin shaft can be disengaged or inserted into the positioning hole at the end close to the positioning support, thereby realizing the support and fixation of the actuator fixed shaft at the required angle, with high reliability and safety.

[0007] Preferably, the number of the positioning holes is 3, which can achieve three-level adjustment. Depending on actual conditions, more or fewer positioning holes can also be designed.

[0008] In order to improve flexibility, convenience and versatility, the positioning support can move up and down in the fixed support.

[0009] In order to improve the stability of the actuator fixed shaft when placed in a horizontal position and prevent it from slipping, a fixed shaft groove matching the actuator fixed shaft is opened on the actuator bracket.

[0010] In order to improve the convenience of debugging and maintenance, the bottom-turning actuator assembly is telescopically connected to the actuator fixed shaft. The bottom-turning actuator assembly includes an actuator connecting shaft, a bottom-turning actuator and a direction adjustment device. The bottom-turning actuator is connected to the lower end of the actuator connecting shaft through the direction adjustment device. The bottom-turning actuator can be adjusted in any direction through the direction adjustment device to control the distance between it and the large hub. When the paper bag is rolled over, the upper and lower layers of paper at the bottom of the paper bag can be effectively separated, which provides convenience for subsequent weaving.

[0011] Furthermore, in order to achieve the best bottom-turning effect, the bottom-turning actuator includes a plurality of bent rod-shaped actuators and plate-shaped actuators.

[0012] The beneficial effects of the present invention are as follows: the bottom-turning rod adjustment device, by designing a positioning support with a positioning hole and being used in conjunction with a pull pin shaft assembly, increases the gear adjustment of the bottom-turning rod and improves the convenience of debugging and maintenance; by designing a retractable and detachable actuator connecting shaft and a direction adjustment device, the height and direction of the bottom-turning actuator can be adjusted, which has a wide range of adaptability and can effectively separate the upper and lower layers of paper at the bottom of the paper bag, greatly improving the convenience of subsequent weaving; and the bottom-turning rod adjustment device has stable support and limiting and strong safety.
