Description

Technical Field

[0001] The utility model relates to the field of plastic bubble film reeling and unreeling devices, in particular to a turning spindle limiting and stabilizing device for plastic bubble films. Background Art

[0002] During the winding process of the plastic bubble film, the stability of the flip spindle is crucial to ensure the neatness and quality of the rolled film. In the prior art, the winding structure often uses a worm gear structure to achieve flipping, but this structure has a gap problem between the turbine and the worm, which causes the box to swing left and right, affecting the accuracy of the rolled film and the stability of the equipment operation. In order to solve the left and right swing of the box, if the transmission mode is difficult to change, it is necessary to add an additional limit device to the flip spindle, but the traditional limiters are installed on the bearing seat limiter on the frame, and the flip spindle will still have a seesaw effect, causing the box to swing. Therefore, an adjustable limit device is needed to limit its swing without affecting the rotation of the flip spindle. Summary of the invention

[0003] The utility model aims at the shortcomings of the prior art and provides a turning main axis limiting and stabilizing device for a plastic bubble film.

By setting the fine-tuning limit block and the limit ring, the deviation of the flip spindle is effectively limited, the stability of the spindle is improved, and the film roll quality problem and the frame swing problem caused by the spindle swing are reduced.

[0006] Preferably, the rotational power source includes a motor, a worm wheel and a worm. The motor is connected to the worm and drives the worm to rotate. The worm cooperates with the outer ring thread of the worm wheel. The rotation plane of the worm wheel is perpendicular to the flip spindle.

[0010] Preferably, the left and right limit blocks are provided with slots contacting the left and right sides of the flip spindle, which are used to limit the flip spindle to the left and right.

[0011] Preferably, the lower limit block can be adjusted up and down relative to the left and right limit blocks, and the top of the lower limit block slides along the groove wall of the slot, so that the upper and lower clamps of the flip spindle are set between the upper arc groove of the lower limit block and the upper groove wall of the slot.

[0012] Preferably, the rolling bearing is connected to a lifting power source so that the fine-tuning limit block can be adjusted up and down on the frame.

The fine-tuning limit block 31 is adjustably mounted on the frame 1, and the limit ring 32 is mounted on the fine-tuning limit block 31; the rolling bearing 7 is located below the fine-tuning limit block 31 and contacts with the fine-tuning limit block 7, and the circumferential surface of the rolling bearing 7 matches the bottom shape of the fine-tuning limit block 31.

[0024] The rotation power source includes a motor 41, a worm wheel 42 and a worm 43. The motor 41 is connected to the worm 43 and drives the worm 43 to rotate. The worm 43 cooperates with the outer ring thread of the worm wheel 42. The rotation plane of the worm wheel 42 is perpendicular to the flip main shaft 2. The rotation of the worm wheel 42 drives the flip main shaft 2 to rotate.

[0025] A bearing seat 5 with a bearing is installed on the frame 1, and the bearing is sleeved on the outer circumference of the turning spindle 2.

[0026] The fine adjustment limit block 31 includes a lower limit block 33 and left and right limit blocks 34 . The lower limit block 33 is fixedly connected to the left and right limit blocks 34 , and the lower limit block 33 is clamped with the rolling bearing 7 .

[0027] The bottom of the lower limit block 33 is provided with a lower arc groove 331 matching the circumferential surface of the rolling bearing 7 , and the upper part of the lower limit block 33 is provided with an upper arc groove 332 for contacting the flip spindle 2 for limiting the lower part of the flip spindle 2 .

[0028] The left and right limit blocks 34 are provided with slots 341 contacting the left and right sides of the flip main shaft 2 for limiting the left and right positions of the flip main shaft 2 .

[0029] like Figure 2-3 As shown, two matching modes of the lower limit block 33 and the left and right limit blocks 34 are provided. The lower limit block 33 is fan-shaped or rectangular. Figure 3 As shown in the fan-shaped, the upper and lower positions of the lower limit block 33 relative to the left and right limit blocks 34 cannot be adjusted. Figure 2 As shown in the straight line, the lower limit block 33 can be adjusted up and down relative to the left and right limit blocks 34, and the top of the lower limit block 33 is guided and slid along the groove wall of the slot 341, so that the upper and lower clamps of the flip spindle 2 are set between the upper arc groove 332 of the lower limit block 33 and the upper groove wall of the slot 341.

[0030] The rolling bearing 7 is connected to a lifting power source 6 so that the fine-tuning limit block 31 can be adjusted up and down on the frame 1.

[0031] The lifting power source 6 is a cylinder, and a fixing seat 62 for axially limiting the output rod 61 of the cylinder is provided on the frame 1.

[0032] Working principle:

[0033] The flip spindle 2 is to be installed on the frame 1. Since the flip spindle 2 rotates under the electric power of the worm gear structure to realize the winding of the roll film, due to the gap between the worm gear, the flip spindle 2 will swing a little bit, so a limit is made. Then this limit is mainly the left and right limit blocks 34 can limit the left and right swing of the flip spindle 2, but when it is necessary to flip, the distance between the left and right groove walls of the left and right limit blocks 34 does not affect the flipping of the flip spindle 2. The upper and lower positions of the lower limit block 33 are determined by using the shape matching of the rolling bearing 7 and the lower part of the lower limit block 33, combined with the connection of the rolling bearing 7 and the lifting power source 6, and the upper arc groove 332 of the lower limit block 33 is used to clamp the flip spindle 2, which completely limits the axial movement and front and back swing of the flip spindle 2. At the same time, the upper arc groove 332 of the lower limit block 33 cooperates with the upper groove wall of the clamping groove 341, which will not affect the rotation of the flip spindle 2.

[0034] The winding system using the worm gear structure successfully realizes the flipping function, and the problem of the left and right swing of the box caused by the structural gap is effectively solved by the cleverly designed limit device. The device ensures that the system can still maintain the required arc accuracy when performing the flipping operation, showing a high degree of attention to details and the ability to overcome technical difficulties. In addition, the rotation and movement restriction of the object is realized through the innovative application of bearing support, which involves the precise customization of a plate and a bearing and a tightly fitting connection method, further improving the stability and support efficiency of the system.
