Description

Technical Field

[0001] The utility model relates to the technical field of winding equipment, in particular to a guide cloth winding and pressing device. Background Art

[0002] A flow guide is a material used to guide and control the flow of liquid or gas, usually made of fiber or other porous materials. It can be used in various occasions, such as air filters, water treatment, chemical engineering and medical equipment.

[0003] During the production and winding process of the guide cloth, a clamping device can be used to ensure that the cloth is rolled tightly and avoid looseness. The traditional clamping device uses the elastic force of the spring to compress the cloth during winding, but the elastic force of the spring changes with the change of deformation, making it difficult to ensure the stability of the clamping force.

[0004] In the prior art, a utility model patent with publication number CN214191817U discloses a winding and clamping device, which uses a pressure sensor to detect pressure and adjusts the position of the pressure roller according to the pressure, thereby reducing the pressure variation range during the clamping process. However, the cost is relatively high and the clamping force cannot be guaranteed to be constant. A utility model patent with publication number CN219173798U discloses a cloth winding and clamping mechanism, which uses a screw to adjust the spring compression amount, thereby limiting the pressure variation range. However, manual adjustment is required and the clamping force cannot be guaranteed to be constant. Utility Model Content

[0005] The utility model aims to provide a guide cloth winding and pressing device in order to solve the problem that the pressing force of the pressing device in the above-mentioned prior art cannot be guaranteed to be constant.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A guide cloth winding and pressing device comprises a plurality of pressing rollers pressed on the outside of the cloth roll and an annular body supporting the ends of the pressing rollers; the pressing rollers are evenly distributed along the circumference of the annular body and move radially along the annular body; the ends of the pressing rollers are connected to a counterweight block through a traction rope toward the center of the annular body.

[0008] Furthermore, the number of the annular bodies is two, which are respectively supported at the two ends of the pressure roller; and a bracket is also included, and the upper end of the bracket supports the annular body.

[0009] Furthermore, a bolt is passed through the upper end of the bracket, and a plurality of mounting holes cooperating with the bolt are evenly distributed on the circumference of the edge of the annular body.

[0010] Furthermore, a sliding seat is provided at the end of each of the pressing rollers, and a plurality of radial strip holes are evenly distributed on the circumference of the annular body, and the sliding seat slides along the strip holes.

[0011] Furthermore, it also includes a through hole for the traction rope to pass through, and the through hole connects the inner ring side of the annular body with the strip hole.

[0012] Furthermore, a notch is provided on the annular body, and the notch enables the inner ring side and the outer ring side of the annular body to communicate with each other.

[0013] Furthermore, a plurality of limiting columns are evenly arranged on the circumference of one side surface of the annular body.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0015] The utility model uses a counterweight block to apply a force toward the center to the pressure roller through a traction rope, so that the pressure roller is pressed tightly against the outside of the cloth roll. Because the gravity of the counterweight block can be kept constant, the pressing force will not change as the radius of the cloth roll increases, and the cloth roll can be tightly rolled up at various places through multiple pressure rollers, thereby improving the rolling effect.

[0016] The utility model enables the pressing roller to move radially through the sliding structure of the slide seat and the strip hole to adapt to the increasing outer diameter of the cloth roll during winding; the traction rope is limited by the perforation, the force direction of the counterweight block is changed, and the gravity of the counterweight block is converted into a force that moves the pressing roller toward the center.

[0026] The present invention is further described in detail below in conjunction with the embodiments.

[0027] Specific embodiments of the guide cloth rolling and pressing device provided by the utility model:

[0028] See also Figure 1-5 The guide cloth winding and pressing device comprises a plurality of pressing rollers 2 pressing on the outside of the cloth roll and an annular body 1 supporting the ends of the pressing rollers 2. In this embodiment, the annular body 1 is in the shape of an annular flat plate, and there are two annular bodies 1, which are respectively supported at the two ends of the pressing roller 2. The winding shaft 13 for winding the guide cloth can pass through the annular body 1, and the guide cloth is wound on the outside of the winding shaft 13 to form a cloth roll, and a plurality of pressing rollers 2 surround and press on the outside of the cloth roll.

[0029] In this embodiment, two brackets 5 are provided, and the upper ends of the two brackets 5 support two annular bodies 1 respectively. Two bolts 6 are penetrated at the upper end of each bracket 5, and a plurality of mounting holes 7 cooperating with the bolts 6 are evenly distributed on the circumference of the edge of the annular body 1. The structure of multiple mounting holes 7 enables the annular body 1 to be installed at multiple angles. The mounting holes 7 can be threaded holes, which can directly cooperate with the bolts 6; the mounting holes 7 can also be plain holes, in which case nuts threadedly connected to the bolts 6 need to be provided.

[0030] In this embodiment, there are four pressing rollers 2, which are evenly distributed along the circumference of the annular body 1 and move radially along the annular body 1; specifically, a slide seat 8 is provided at the end of each pressing roller 2, and a plurality of radial strip holes 9 are evenly distributed on the circumference of the annular body 1, and the slide seat 8 slides along the strip holes 9. In this embodiment, four strip holes 9 are provided on each annular body 1, and the four strip holes 9 correspond to the four pressing rollers 2 one by one.

[0031] The slide 8 includes a shaft seat and a slider, the shaft seat and the slider are connected, the shaft seat rotatably supports the pressure roller 2, the slider has an I-shaped cross-section, can be stuck in the strip hole 9, and move along the strip hole 9. The slider enables the slide 8 to move in the radial direction and linearly of the annular body 1. Both ends of the pressure roller 2 are supported by the slide 8, so that the pressure roller 2 can both rotate and move in the radial direction of the cloth roll.

[0032] The end of the pressing roller 2 is connected to a counterweight 4 through a traction rope 3 on one side facing the center of the annular body 1; specifically, the traction rope 3 is connected to the slider. The annular body 1 is provided with a through hole 10 for the traction rope 3 to pass through, and the through hole 10 connects the inner ring side of the annular body 1 with the strip hole 9; each strip hole 9 is provided with a through hole 10 at the inner end, and the traction rope 3 passes through the through hole 10 and then hangs down and connects to the counterweight 4, so that the counterweight 4 exerts force downward by itself, and the traction rope 3 changes direction through the through hole 10, so that the gravity of the counterweight 4 changes to a force that moves the slide 8 toward the center of the annular body 1, and then the slide 8 and the pressing roller 2 can move toward the center, and the pressing roller 2 presses the cloth roll toward the center, and as the position of the slide 8 and the pressing roller 2 changes, the pressing force remains constant.

[0033] In this embodiment, the material of the counterweight 4 can be lead. Figure 2 As described above, the weight of the counterweight block 4 connected to the two lower slides 8 can be greater than the weight of the counterweight block 4 connected to the upper slide 8, because the gravity of the two upper pressure rollers 2 can cooperate with the counterweight blocks 4 connected to them to apply pressure to the cloth roll, while the weight of the lower pressure roller 2 offsets part of the gravity of the counterweight block 4 connected to it.

[0034] In this embodiment, a notch 11 is provided on the annular body 1, and the notch 11 connects the inner ring side and the outer ring side of the annular body 1. The notches 11 on the two annular bodies 1 correspond to each other. The function of the notch 11 is: after the guide cloth is rolled up, the winding shaft 13 with the cloth roll can be taken out from the notch 11, and the width of the notch 11 is greater than the outer diameter of the winding shaft 13.

[0035] A plurality of limit columns 12 are evenly arranged on the circumference of one side of the annular body 1. The function of the limit columns 12 is to support the traction rope, so that the traction rope 3 is passed around the limit columns 12 (not shown in the drawings), the sagging position of the counterweight 4 is changed, and mutual interference is avoided when the counterweight 4 rises.

[0036] The external winding device rotates the winding shaft 13, and the winding shaft 13 rotates to wind the guide cloth 14 to be rolled up on its outside to form a cloth roll; the gravity of the counterweight block 4 applies a constant force toward the center to the slide 8 and the pressure roller 2 through the traction rope 3; as the guide cloth 14 to be rolled up continues to be rolled up, the radius of the cloth roll gradually increases; the slide 8 and the pressure roller 2 gradually move away from the center along the strip hole 9 and continue to press on the outside of the cloth roll, and the counterweight block 4 gradually rises.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments without creative work, or replace some of the technical features therein with equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
