Description

Technical Field

[0001] The utility model relates to the technical field of packaging equipment, in particular to a sealing fork adjusting device for a medium-sized packaging machine of sanitary products. Background Art

[0002] In the existing technology, such as the sealing and forming device of the medium-sized packaging machine for sanitary products disclosed in CN208070162U, the mechanism for limiting the bag opening shown in Figure 4 of the attached drawings can be well adjusted to the required size through a fork, so that the product can be formed into a bag. However, for the existing structure, if it is necessary to adjust the fork according to the size of different packaging bags, it is necessary to stop the machine and adjust the position of the rotary clamping cylinder on the upper and lower support plates, and the adjustment time is relatively long, which affects the production efficiency. Summary of the Invention

[0003] The utility model aims to overcome the deficiencies of the existing technology and provides a sealing fork adjusting device for a medium-sized packaging machine of sanitary products.

[0004] To achieve the above object, a sealing fork adjusting device for a medium-sized packaging machine of sanitary products is designed, which includes a lead screw. The lead screw is a double-threaded lead screw with opposite pitches, and the lead screw is connected to a rotary driving device. The two sides of the lead screw are respectively screwed with an upper connecting block. Above the lower connecting block, a lower rotary clamping cylinder and a series of optical rods are fixedly installed. The lower rotary clamping cylinder is connected with a fork. Above the series of optical rods, an upper connecting block is installed. Below the upper connecting block, an upper rotary clamping cylinder is fixed, and the upper rotary clamping cylinder is also connected with a fork.

[0005] A synchronous pulley is fixed on the lead screw, and the synchronous pulley is connected to a servo motor through a synchronous belt.

[0006] The upper connecting block is connected with a guide rail through a slider.

[0007] The guide rail is fixed on a mounting plate. Above the lifting plate, a fixed cylinder mounting plate is provided. A linear cylinder is fixed on the cylinder mounting plate, and the piston rod of the linear cylinder is connected to the lifting plate. The upper connecting block is connected to the series of optical rods through a linear bearing.

[0008] Compared with the existing technology, the utility model drives the double-threaded lead screw with opposite pitches to rotate through a rotary driving device, so that the forks can move inwards or outwards simultaneously, and the position of the sealing fork of the medium-sized packaging machine can be automatically adjusted, avoiding manual adjustment, with a fast and accurate tool change speed.

Detailed implementation mode

[0011] The following further describes the present invention with reference to the accompanying drawings.

[0012] As Figure 1 shown, the lead screw 1 is a double-threaded lead screw. The lead screw 1 is connected to a rotary drive device. The two sides of the lead screw 1 are respectively screwed with the lower connecting block 5. Above the lower connecting block 5, a lower rotary clamping cylinder 6 and a series of optical rods 8 are fixedly installed. The lower rotary clamping cylinder 6 is connected with a fork 7. Above the series of optical rods 8, an upper connecting block 9 is installed. Below the upper connecting block 9, an upper rotary clamping cylinder 10 is fixed. The upper rotary clamping cylinder 10 is also connected with a fork 7.

[0013] The lead screw 1 is fixed with a synchronous pulley 2. The synchronous pulley 2 is connected to the servo motor 4 through a synchronous belt 3.

[0014] The upper connecting block 9 is connected to the guide rail 12 through a slider 11. Through the cooperation of the guide rail 12 and the slider 11, the upper connecting block 9 can be accurately moved in a straight line to the position, and the frictional resistance is reduced during the movement.

[0015] The guide rail 12 is fixed on the lifting plate 13. Above the lifting plate 13, a fixed cylinder mounting plate 14 is provided. The cylinder mounting plate 14 is fixed with a linear cylinder 15. The piston rod of the linear cylinder 15 is connected to the lifting plate 13. The upper connecting block 9 is connected to the series of optical rods 8 through a linear bearing one 17.

[0016] Below the two sides of the cylinder mounting plate 14, guide rods 16 are fixed. The two sides of the lifting plate 13 are cooperated with the guide rods 16 through linear bearings two 18.

[0017] When the present invention is used, the upper connecting block 9 is connected in series with the lower connecting block 5 through the series of optical rods 8. When the rotary drive device drives the lead screw 1 to rotate, through the cooperation of the two lower connecting blocks 5 with the two sides of the double-threaded lead screw respectively, the upper rotary clamping cylinder 10 and the lower rotary clamping cylinder 6 can move inwards or outwards synchronously, which is convenient for adjusting the position of the fork for sealing the tundish of the caster.

[0018] The servo motor 4, as a rotary driving device, can accurately drive the lead screw 1 to rotate through the synchronous belt 3 and the synchronous pulley 2, so that the lower connecting block 5 reaches the set position. During the first production, the correct position of the fork 7 can be found by jogging, and then the position parameters are saved in the PLC. The data can be directly called the next time it is used, without manual adjustment of the position of the fork 7.

[0019] The cylinder mounting plate 14 can be fixedly connected to the frame of the equipment. The telescopic movement of the linear cylinder 15 can adjust the height of the lifting plate 13. The upper connecting block 9 can move up and down along the series of optical rods 8 through the linear bearing 1, so as to adjust the height of the upper rotary clamping cylinder 10 to adapt to products of different heights. The cooperation between the guide rod 16 and the lifting plate 13 can keep the lifting plate 13 balanced.
