Description

Technical Field

[0001] The utility model relates to the technical field of winding machines, in particular to a lifting column structure of a winding machine. Background Art

[0002] A winding machine is a packaging device. The film rack is installed on the column. During use, the mold rack needs to be lifted and lowered to meet the winding requirements of items at different heights. The film rack of the existing winding machine is lifted and lowered along the column. Therefore, the overall height of the column is relatively large, occupying a large space. Content of the Utility Model

[0003] In order to solve the above problems existing in the prior art, the utility model provides a lifting column structure of a winding machine that greatly reduces the height of the column without changing the lifting stroke of the film rack.

[0004] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0005] A lifting column structure of a winding machine includes a column frame, a first column vertically slidably arranged in the column frame, and a film rack vertically slidably connected to the first column; driving wheels are arranged at both the upper and lower ends of the column frame, a driving chain is arranged between the two driving transmission wheels, and a power assembly for driving the driving wheel to rotate is arranged on one of the driving wheels, and the first column is fixedly connected to the driving chain; a first transmission wheel is rotatably arranged at the upper end of the first column, a first transmission chain is arranged on the first transmission wheel, one end of the first transmission chain is fixedly connected to the bottom of the column frame, and the other end of the first transmission chain bypasses the first transmission wheel and is connected to the film rack.

[0006] When the first column rises, the film rack is synchronously driven to rise through the first transmission chain, thereby increasing the lifting stroke of the film rack. When the first column descends, the first film rack also descends along the film rack. When the first column is completely retracted into the column frame, the overall height is smaller and the occupied space is also smaller.

[0007] Preferably, first sliding rails are arranged on both sides of the inner wall of the column frame, and a first sliding seat slidably connected to the first sliding rail is fixedly arranged at the lower end of the first column; second sliding rails are arranged on both sides of the first column, and second sliding seats slidably matched with the second sliding rails are fixedly arranged on both sides of the film rack.

[0008] Preferably, a first chain seat is fixedly arranged on the side surface of the lower end of the first column, and adjusting parts for adjusting the tightness are arranged at both ends of the driving chain and connected to the first chain seat. The tightness of the driving chain can be adjusted through the adjusting parts.

[0009] Preferably, the adjusting member is configured as a screw rod. Adjusting holes are provided at both ends of the first chain seat. Two screw rods respectively pass through the two adjusting holes, and adjusting nuts are provided on the screw rods. The tightness is adjusted by the screw rod and the adjusting nut.

[0010] Preferably, a second chain seat is fixedly provided on the film rack, and an adjusting member for connecting with the second chain seat is provided at the end of the first transmission chain.

[0011] Preferably, the power assembly is arranged at the upper end of the column frame and is connected with the driving wheel.

[0012] Preferably, the power assembly is configured as a right-angle reduction motor, and the driving wheel and the first transmission wheel are both configured as sprockets. Using a right-angle reduction motor can reduce the lateral dimension, making the overall layout occupy less space.

[0013] Preferably, a partition is provided at the position between the film rack and the first transmission chain inside the first column.

[0014] Therefore, the utility model has the beneficial effects of small overall occupied space and large lifting stroke of the film rack. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] As Figures 1 - 5 shown, a lifting column structure of a winding machine includes a column frame 10, a first column 20 vertically slidably arranged in the column frame 10, and a film frame 40 vertically slidably connected to the first column 20. A partition 50 is provided at a position in the first column 20 between the film frame 40 and the first drive chain 22; drive wheels 11 are provided at both the upper and lower ends of the column frame 10, a drive chain 12 is provided between the two drive transmission wheels, and a power assembly 13 for driving the drive wheel 11 to rotate is provided on one of the drive wheels 11. The first column 20 is fixedly connected to the drive chain 12; a first transmission wheel 21 is rotatably provided at the upper end of the first column 20, a first drive chain 22 is provided on the first transmission wheel 21, one end of the first drive chain 22 is fixedly connected to the bottom of the column frame 10, and the other end of the first drive chain 22 bypasses the first transmission wheel 21 and is connected to the film frame 40.

[0023] In this embodiment, the power assembly 13 is arranged at the upper end of the column frame 10 and connected to the drive wheel 11. The power assembly 13 is configured as a right-angle reduction motor, and both the drive wheel 11 and the first transmission wheel 21 are configured as sprockets.

[0024] On both sides of the inner wall of the column frame 10, first slide rails 14 are provided. A first sliding seat 23 slidably connected to the first slide rail is fixedly provided at the lower end of the first column 20; second slide rails 25 are provided on both sides of the first column 20, and second sliding seats 41 slidably engaged with the second slide rails are fixedly provided on both sides of the film frame 40. In some embodiments, the first slide rail and the second slide rail can adopt slide bars, linear guide rails, dovetail guide rails, etc., and the first sliding seat and the second sliding seat can adopt corresponding sliding sleeves, linear sliders, dovetail sliders, etc.

[0025] A first chain seat 24 is fixedly provided on the side surface of the lower end of the first column 20. Adjusting members 110 for adjusting the tension are provided at both ends of the drive chain 12 and connected to the first chain seat 24; the adjusting member 110 is configured as a screw rod. Adjusting holes 240 are provided at both ends of the first chain seat 24, and two screw rods respectively pass through the two adjusting holes, and adjusting nuts (not shown in the figure) are provided on the screw rods.

[0026] A second chain seat 42 is fixedly provided on the film frame 40, and an adjusting member 110 connected to the second chain seat 42 is provided at the end of the first drive chain 22.

[0027] Combined with the attached drawings, the principle of the present utility model is as follows: As Figure 1As shown, the first upright column is inside the upright column frame, and at this time the overall height is relatively small; when the film frame needs to rise, the power assembly drives the driving wheel and the driving chain to rotate. Since the first upright column is connected to the driving chain through the first chain seat, the first upright column rises under the action of the driving chain. Since the lower end of the first transmission chain is fixed to the bottom of the upright column frame, when the first upright column rises, the upper end of the first transmission chain drives the film frame to rise along the first upright column. The state of the film frame after rising is as shown in Figure 3 shown. This structure increases the stroke of the film frame, that is, when meeting the stroke requirement of the film frame, the height of the upright column frame and the height of the first upright column can be designed to be smaller, so that the overall occupied space is smaller.

[0028] In the description of the present invention, it should be understood that the directions or positional relationships indicated by up and down, left and right, inner end, outer end, one end, the other end, etc. are based on the orientation or positional relationship shown in the drawings, and are only for more clearly facilitating the description of the technical solution of the present invention, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific orientation, and should not be construed as a limitation to the present invention.

Various substitutions, changes and modifications can be conceived without departing from the spirit and scope of the present invention.
