[0028] It should be noted that: similar labels and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. EMBODIMENT

[0029] The following will be further illustrated in combination with specific embodiments, with reference to Figures 1-7As shown, the embodiment is a pressure-adjustable bandage guiding device, which comprises at least one guide wheel unit 1, the guide wheel unit 1 comprising a wheel body 15, a supporting piece 151, a push shaft 141, a mounting plate 11 and a first motor 12, the mounting plate 11 being provided with a hollow shaft sleeve 14, the lower end of the first motor 12 being connected with a gland cylinder 13 which is threadedly connected with the hollow shaft sleeve 14, the push shaft 141 being arranged in the hollow shaft sleeve 14, and a compression spring 16 being arranged between the gland cylinder 13 and the push shaft 141; a guide shaft 111 is mounted on the mounting plate 11, the first motor 12 being connected with the guide shaft 111 in sliding fit, and the first motor 12 drives the gland cylinder 13 to rotate synchronously and compress the compression spring 16; the wheel body 15 is connected with the supporting piece 151, and the upper end of the supporting piece 151 is connected with the lower end of the push shaft 141; specifically, the device is provided with multiple guide wheel units 1 which cooperate with a cloth supporting surface, so that the cloth is pressed between the supporting surface and the wheel body 15, and there are at least two guide wheel units 1 in the length direction of the cloth, the first motor 12 is energized to rotate and move downward along the guide shaft 111, so that the gland cylinder 13 presses the compression spring 16 downward, the compression amount is increased to generate elastic feedback to the push shaft 141 and the wheel body 15, the pressure of the wheel body 15 acting on the cloth is increased, and thus the cloth is straightened better and is not easy to produce deviation and wrinkles, the device has the effect of automatic adjustment, and is suitable for different equipment and has good universal performance.

[0030] It should be noted that the guide wheel unit 1 mainly has the effect of vertical pressure adjustment, bearings, stop rings and gaskets and other parts are also mounted between the wheel body 15 and the supporting piece 151, and a jam screw is used to avoid the left and right deviation of the wheel body 15, so that the wheel body 15 only has one degree of freedom of rotation; and the manual knob directly connected with the first motor 12 is used to reserve the manual adjustment function.

[0031] As shown in the figure, Figure 1 and Figure 3As shown, in order for the device to have the ability to adjust pressure in the horizontal direction, that is, to improve the straightening effect of the fabric in the width direction, the guide wheel unit 1 in this embodiment is also connected to a horizontal power component 2. The horizontal power component 2 includes a horizontal fixed bracket 22, a mounting frame 21, and a second motor 27. The horizontal fixed bracket 22 is connected to the mounting frame 21. The second motor 27 is mounted on the mounting frame 21 and is connected in sequence to a lead screw 26 and a first sleeve 24. The horizontal fixed bracket 22 is provided with a second sleeve 23. A first spring 241 is installed in the first sleeve 24 and a second spring 231 is installed in the second sleeve 23. Both ends of the mounting plate 11 are provided with force-bearing protrusions 112, which are respectively inserted into the first sleeve 24 and the second sleeve 23. Specifically, if the wheel bodies 15 of the two guide wheel units 1 are set to act on the two sides of the fabric, when the horizontal power component 2 of one guide wheel unit 1 is not working, the second motor 27 of the horizontal power component 2 of the other guide wheel unit 1 is started, and the fabric is in a state where horizontal force is required. At this point, the first sleeve 24 is moved to the left by the second motor 27 and the lead screw 26. This is the equilibrium position; the force F1 of the first spring 241 is less than the force F2 of the second spring 231. The fabric provides a rightward frictional force f, achieving equilibrium. Since the right-side wheel 15 of the fabric is fixed horizontally, the fabric will be taut due to the outward frictional force from both wheels 15 in the width direction. Similarly, when it is necessary to reduce the tension or apply a force in the opposite direction, simply move the first sleeve 24 in the opposite direction.

[0032] Reference Figure 6 As shown, in order to enable the lead screw 26 to drive the first sleeve 24 to achieve smooth horizontal movement, in this embodiment, the first sleeve 24 is provided with horizontal guide rods 25 on both sides, and the first sleeve 24 is slidably connected to the horizontal guide rods 25.

[0033] like Figure 6 As shown, in this embodiment, the mounting frame 21 is provided with a first adjustment through-hole 211, and the horizontal fixing bracket 22 is provided with a second adjustment through-hole 221 corresponding to the first adjustment through-hole 211. The first adjustment through-hole 211 and the second adjustment through-hole 221 are connected in series with screws for fixation. Specifically, the mounting frame 21 has a bayonet on one side, and the horizontal fixing bracket 22 is a U-shaped frame that can be inserted into the bayonet. In order to adapt to different sizes of mounting plates 11, the horizontal fixing bracket 22 and the mounting frame 21 can be moved in opposite directions or in opposite directions to adjust their positions, and are locked by screws and nuts passing through the first adjustment through-hole 211 and the second adjustment through-hole 221.

[0034] Reference Figure 1 and Figure 2As shown, the embodiment further comprises a workbench 3, the guide wheel unit 1 further comprises a side plate support 4 detachably connected with the workbench 3, one end of the side plate support 4 is connected with the mounting plate 11, and the guide wheel units 1 are arranged in pairs and distributed on both sides of the workbench 3; specifically, the cloth is placed on the workbench 3, and two guide wheel units 1 form a group to change the straightness of the width direction of the cloth, and multiple groups of guide wheel units 1 are evenly arranged along the workbench 3 to adjust the straightness of the length direction of the cloth.

[0035] As shown in the drawings, Figure 6 As shown, the mounting plate 11 in the embodiment is provided with a first waist-shaped hole 113 for mounting one end of a guide shaft 111, and the mounting plate 11 is further provided with a second waist-shaped hole 114 for passing a push shaft 141; specifically, the first waist-shaped hole 113 and the second waist-shaped hole 114 are used for position adjustment of the wheel body 15, changing the contact position of the wheel body 15 with the cloth, so as to change the interval distance of the two wheel bodies 15 in the same group of guide wheel units 1.

[0036] More preferably, the length direction of the first waist-shaped hole 113 and the second waist-shaped hole 114 is consistent with the axis of the wheel body 15.

[0037] The support 151 in the embodiment adopts a U-shaped bent plate, the wheel body 15 is arranged between the supports 151, and the U-shaped bent plate makes the wheel body 15 uniformly stressed on both sides, and the stability is better.

[0038] The above is only the preferred embodiment of the utility model, and is not used for limiting the utility model, and for the person skilled in the art, the utility model can have various changes and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
