Description

Technical Field

[0001] The invention relates to the technical field of textile machinery, in particular to a cloth winding roller and a cloth winding machine. Background Art

[0002] In the textile industry, in order to be able to store the woven fabric well, people invented the cloth roller. The cloth is rolled up by the rotation of the cloth roller. After rolling up, the cloth can be removed from the loom and replaced with a new cloth roller to continue rolling up.

[0003] The Chinese utility model patent, authorization number "CN211971384U" discloses a new type of cloth rolling roller with a simple structure that can effectively reduce the weight of the cloth rolling roller, including a thin-walled drum for rolling up the cloth, a magnet block, a hollow rotating shaft and other components.

[0004] The Chinese invention patent, publication number "CN107012573A" discloses a cloth roller tensioning cloth winding device, which solves the technical problem of adjusting the cloth roller tension, and at the same time realizes the rapid removal of the wound cloth, solving the technical problem of how to quickly detach the cloth roller from the cloth and reuse it.

[0005] For another example, the Chinese invention patent, publication number "CN109132629A" discloses a cloth winding roller for knitted fabric production that is easy to retract and release, which can achieve a certain limiting effect on the cloth winding roller, preventing the cloth winding roller from moving during rotation and affecting the normal work of the cloth winding, thereby avoiding problems such as dislocation and looseness of the cloth.

[0006] The cloth rolling rollers used in the prior art and on the market have at least the following defects in practical applications:

[0007] First of all, when the cloth roller is winding the cloth, in order to ensure a constant winding force of the cloth, as the diameter of the wound cloth becomes larger and larger, the torque driving the cloth roller to rotate will also become larger and larger, and the torque will cause the cloth roller to generate additional eccentric force, which will affect the rotational stability of the cloth roller, and after working for a long time, it may cause the stability of the machine to deteriorate.

[0008] Secondly, the cloth is guided by multiple cloth guide rollers, and then the friction between the driving roller and the cloth winding roller drives the cloth winding roller to rotate to realize the winding of the cloth. In this way, the surface of the driving roller generates high temperature due to the friction for a long time. When winding, the heat of the roller body will be transferred to the surface of the cloth. Since the cloth is wound around the roller body of the cloth winding roller in a circle, the heat dissipation of the cloth is slow, which may cause the cloth to deform due to uneven shrinkage of the cloth fibers, affecting the quality of the final product. Summary of the invention

[0009] The object of the present invention is to provide a cloth rolling roller and a cloth rolling machine to solve the problems raised in the above background technology.

[0010] To achieve the above object, the present invention provides the following technical solution: a cloth rolling roller, comprising a roller, bearings are arranged on both sides of the roller, and the end of the roller is fixed to the outer ring of the bearing through an annular plate;

[0011] A movable block is arranged on the outer side of the bearing, the movable block is fixed to the inner ring of the bearing by a fixing rod, and a rotating shaft is movably connected between the two inner rings of the bearings on both sides;

[0012] An air inducing member and a driving member are arranged on the shaft body of at least one side of the rotating shaft. When the roller rotates, the rotating shaft rotates in the opposite direction to the rotating direction of the roller under the drive of the driving member.

[0013] The outer side of the roller is provided with a plurality of ventilation grooves distributed in a transverse direction, and the central circumferential array of the roller has at least one group of air outlet holes, which are connected to the inner cavity of the roller. The middle of the fixed rod and the movable block are respectively provided with connecting holes and air induction holes, which are connected to the inner cavity of the roller.

[0014] Under the action of the air induction member, the outside air enters the inner cavity of the roller through the air induction holes and the connecting holes, and then enters the ventilation groove through the air outlet holes to cool the fabric rolled up on the outside of the roller.

[0015] Furthermore, an annular support plate is integrally formed on both sides of the roller, the outer surface of the annular support plate is on the same plane as the outer surface of the roller, the cloth is rolled up on the roller body between the outer end surfaces of the two annular support plates, and the outer side of the plate body of the annular support plate is provided with a heat dissipation hole connected to the ventilation groove.

[0016] Furthermore, a trumpet-shaped arc-shaped air guide plate is fixed to the outer side of the annular plate, and the hot air flowing out of the ventilation groove is blocked by the arc-shaped air guide plate and then diffused along the radial direction of the roller.

[0017] Furthermore, the movable block is a rectangular block, and grooves are provided on opposite sides thereof, fixed shafts are fixed on both sides of the grooves, and movable wheels are movably connected to the shaft body of the fixed shaft.

[0018] Furthermore, the induced draft member is an induced draft fan. When the roller reels the fabric, the rotating shaft drives the induced draft fan to rotate. At this time, the inner cavity of the roller on the side of the induced draft fan close to the end of the roller is under negative pressure.

[0019] Furthermore, a counterweight rod is fixed to the middle of the shaft body of the rotating shaft, and the induced draft fan is connected to one side of the counterweight rod.

[0020] Furthermore, the driving member includes an internal gear fixed on the inner wall of the roller and a roller shaft rotatably connected to the inner ring of the bearing, a first gear is fixed to the end of the roller shaft, and the first gear is meshed with the internal gear;

[0021] A second gear is fixed on the shaft body of the roller, a third gear is fixed on the shaft body of the rotating shaft, and the second gear is meshed with the third gear.

[0022] Furthermore, the gear ratios of the first gear and the second gear are equal, and the gear ratio of the third gear and the internal gear is 1:1-6.

[0023] Furthermore, a filter is fixed to the end of the movable block for filtering the introduced air.

[0024] A cloth rolling machine also includes two side plates. Guide plates are fixed on the sides of the side plates. A guide groove is formed in the middle of the guide plate. Tracks are arranged on the guide plate bodies on both sides of the guide groove. The movable block moves along the track.

When driven by the driving member, the rotating shaft rotates in the opposite direction to the roller, and the central axes of the roller and the rotating shaft coincide, so that the rotating shaft torque can offset a part of the roller torque, thereby reducing the additional eccentric force generated by the cloth winding roller during the winding process, and improving the rotation stability of the cloth winding roller and the structural stability of the machine.

[0027] At the same time, ventilation grooves, air outlet holes, heat dissipation holes and induced draft fans are provided. The heat on the surface of the driving roller body will be transferred to the surface of the cloth, and the temperature of the innermost side of the cloth wrapped around the cloth winding roller body will be transferred to the ventilation groove. When winding, the rotating shaft drives the induced draft fan to rotate, and the outside air enters the ventilation groove through the air outlet holes and exchanges heat with the innermost cloth. The hot air after heat exchange is discharged along both sides of the ventilation groove. The cloth wound on the outside of the roller is cooled down through heat conduction, which improves the heat dissipation speed of the cloth, makes the cloth fibers shrink evenly, and improves the quality of the final product.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] like Figure 1-Figure 5 As shown, the present invention provides a technical solution: a cloth rolling roller, including a roller 101, in order to reduce the overall weight of the cloth rolling roller, the roller 101 is made of a lightweight stainless steel tube or aluminum alloy tube material, and bearings 105 are arranged on both sides of the roller 101, wherein the bearing 105 includes an outer ring and an inner ring, and the outer ring and the inner ring are rotatably connected by steel balls. In this solution, the inner ring is a circular block structure, and the end of the roller 101 is fixed to the outer ring of the bearing 105 by an annular plate 112, and the annular plate 112 is made of an aluminum alloy material with high rigidity, and a movable block 112 is arranged on the outer side of the bearing 105. 07, the movable block 107 is fixed to the inner ring of the bearing 105 by a fixed rod 106, and the inner rings of the two bearings 105 on both sides are movably connected with a rotating shaft 109, and the central axis of the rotating shaft 109 coincides with the central axis of the roller 101. In order to increase the overall strength of the cloth winding roller, the fixed rod 106 is a solid stainless steel rod body, and its two ends are respectively welded and fixed to the movable block 107 and the inner ring of the bearing 105. In actual application, because the movable block 107 does not rotate, the roller 101 can rotate around the inner ring of the bearing 105 under the drive of external force, thereby realizing the winding of the cloth.

[0037] like Figure 2 As shown, an air inducing member and a driving member are provided on the shaft of at least one side of the rotating shaft 109 . However, in a specific embodiment of the present scheme, in order to improve the overall stability of the cloth rolling roller, two groups of air inducing members and driving members are provided, which are symmetrically distributed on both sides of the rotating shaft 109 .

[0038] When the roller 101 rotates, driven by the driving member, the rotation direction of the rotating shaft 109 is opposite to the rotation direction of the roller 101 .

[0039] Specifically, Figure 3 , Figure 4 and Figure 5 As shown, the driving member includes an internal gear 116 fixed on the inner wall of the roller 101 and a roller 117 rotatably connected to the inner ring of the bearing 105, a first gear 118 is fixed to the end of the roller 117, and the first gear 118 is meshed with the internal gear 116, a second gear 119 is fixed on the shaft of the roller 117, a third gear 120 is fixed on the shaft of the rotating shaft 109, and the second gear 119 is meshed with the third gear 120.

[0040] It can be understood that when the roller 101 rotates under the drive of an external force (assuming it rotates counterclockwise), the internal gear 116 drives the first gear 118 to rotate counterclockwise. Since the second gear 119 and the first gear 118 are coaxially arranged, the second gear 119 rotates counterclockwise. Since the second gear 119 and the third gear 120 are meshed, the third gear 120 rotates clockwise, thereby driving the rotating shaft 109 to rotate clockwise. In this solution, in order to increase the rotational inertia of the rotating shaft 109 and thus increase the torque generated when the rotating shaft 109 rotates, a counterweight rod 111 is fixed to the middle part of the shaft body of the rotating shaft 109. In this way, since the rotation directions of the roller 101 and the rotating shaft 109 are different, and the central axes of the roller 101 and the rotating shaft 109 coincide, the torque of the rotating shaft 109 can offset part of the torque of the roller 101, thereby reducing the additional eccentric force generated by the cloth winding roller during the winding process, and improving the rotation stability of the cloth winding roller and the structural stability of the machine.

[0041] Of course, the driving member can also be a gear pair structure composed of various other methods.

[0042] like Figure 3 , Figure 4 and Figure 5As shown, a plurality of ventilation grooves 102 distributed laterally are provided on the outer side of the roller 101, and the plurality of ventilation grooves 102 are equidistantly distributed on the outer side of the roller 101. In order to increase the friction between the roller 101 and the driving roller 3 driving the roller 101 to rotate, thereby driving the roller 101 to rotate, the width of the ventilation groove 102 is set to 3-10 mm, and at least one group of air outlet holes 103 is provided in a circular array in the middle of the roller 101, and the air outlet holes 103 are connected to the inner cavity of the roller 101, and a connecting hole 114 and an air induction hole 115 that are connected are respectively provided in the middle of the fixed rod 106 and the movable block 107, and the connecting hole 114 is connected to the inner cavity of the roller 101. Since the rotating shaft is arranged in the middle position of the fixed rod 106, in order to increase the air output, a plurality of connecting holes 114 are arranged around the outer side of the fixed rod 106.

[0043] In a specific embodiment of the present scheme, the induced draft member is an induced draft fan 110, specifically a positive pressure fan. Specifically, two induced draft fans 110 are connected on both sides of a counterweight rod 111. When the roller 101 reels the fabric, the rotating shaft 109 drives the induced draft fans 110 to rotate. At this time, the inner cavity of the roller 101 on the side of the induced draft fan 110 close to the end of the roller 101 is at a negative pressure. Correspondingly, the inner cavity of the roller 101 between the two induced draft fans 110 is at a positive pressure, so that under the action of the induced draft fans 110, outside air enters the inner cavity of the roller 101 through the induced draft holes 115 and the connecting holes 114, and then enters the ventilation groove 102 through the air outlet 103.

[0044] In another specific embodiment of the present scheme, the induced draft fan 110 is a negative pressure fan. Specifically, two induced draft fans 110 are connected to both sides of the counterweight rod 111. When the roller 101 reels the fabric, the rotating shaft 109 drives the induced draft fan 110 to rotate. At this time, the inner cavity of the roller 101 on the side of the induced draft fan 110 close to the end of the roller 101 is at a positive pressure. Correspondingly, the inner cavity of the roller 101 between the two induced draft fans 110 is at a negative pressure, so that under the action of the induced draft fan 110, the outside air enters the air outlet 103 through the ventilation groove 102, and then enters the inner cavity of the roller 101. After that, it is discharged through the connecting hole 114 and the air induced ventilation hole 115. However, this embodiment has certain defects. For example, since the outside air contains a certain amount of dust, when the air enters the ventilation groove 102, it will gather to the outside of the rolled cloth. In this way, the outside dust may adhere to the two ends of the rolled cloth, thereby affecting the quality of the cloth. Therefore, in this scheme, as a preferred embodiment, the induced ventilation fan 110 uses a positive pressure fan, that is, as the roller 101 rolls up the cloth, when the induced ventilation fan 110 rotates, the inner cavity of the roller 101 on the side of the induced ventilation fan 110 close to the end of the roller 101 is at negative pressure.

[0045] Specifically, during winding, the heat on the surface of the driving roller 3 will be transferred to the surface of the cloth, and the temperature of the innermost side of the cloth wound around the cloth winding roller will be transferred to the ventilation groove 102. The outside air enters the ventilation groove 102 through the air outlet 103 and exchanges heat with the innermost cloth. The hot air after heat exchange is discharged along the two sides of the ventilation groove 102. Through the conduction of heat, the cloth wound on the outside of the roller 101 is cooled.

[0046] It can also be understood that in the present embodiment, the air outlet 103 is arranged in the middle of the roller 101, so that the external cold air can enter the ventilation groove 102 through the inner cavity of the roller 101, and then be discharged along the two sides of the ventilation groove 102. Compared with the external cold air entering from one side of the ventilation groove 102 and exiting from the other side, the middle arrangement of the air outlet 103 can significantly improve the heat exchange efficiency and effect.

[0047] Of course, in other embodiments, the air inducing member may also be a spiral blade fixed on the shaft 109 , or other components that can rotate with the shaft 109 to increase the air pressure in the middle inner cavity of the roller 101 .

[0048] In the early stage of cloth rolling of roller 101, due to the small weight of roller 101 and the multiple ventilation grooves 102 provided on the surface of roller 101, the friction between roller 101 and driving roller 3 will be reduced, so that roller 101 may slip on driving roller 3 and fail to roll up the cloth. In the present scheme, annular support plates are integrally formed on both sides of roller 101, and the outer surface of the annular support plate is located on the same plane as the outer surface of roller 101. In order to further increase the friction between driving roller 3 and roller 101 and realize that driving roller 3 drives roller 101 to rotate, magnetic powder can be sprayed on the surface of the annular support plate to attract driving roller 3. When rolling up, the cloth is rolled up on the cylinder body of roller 101 between the outer end surfaces of the two annular support plates. Correspondingly, heat dissipation holes 104 connected with ventilation grooves 102 are provided on the outer side of the plate body of the annular support plate.

[0049] In order to prevent the hot air ejected through the heat dissipation holes 104 from entering the air inlet holes 115, in the present embodiment, a trumpet-shaped arc-shaped air guide plate 113 is fixed to the outer side of the annular plate 112, so that the hot air flowing out of the ventilation grooves 102 and the heat dissipation holes 104 is blocked by the arc-shaped air guide plate 113 and then diffused along the radial direction of the roller 101. When the roller 101 rotates, the air on both sides thereof forms an airflow, thereby blowing the hot air into the factory, effectively improving the heat dissipation efficiency of the cloth.

[0050] In order to prevent the movable block 107 from axially rotating during the lifting of the roller 101 and reduce the friction between the cloth rolling roller and the cloth rolling machine, in the present embodiment, the movable block 107 is configured as a rectangular block, and grooves are provided on the opposite sides thereof, fixed shafts are fixed on both sides of the grooves, and a movable wheel 108 is movably connected to the shaft body of the fixed shaft. In this way, it is possible to prevent the cloth rolling roller from experiencing a sudden torque change due to excessive friction between the cloth rolling roller and the cloth rolling machine, thereby avoiding inconsistent winding tension of the cloth, and thereby improving the winding quality of the cloth.

[0051] As the rolled thickness of the fabric on the roller 101 increases, the rotation speed of the roller 101 will decrease accordingly. To ensure that the rotation of the induced draft fan 110 can drive the circulation of air in the inner cavity of the roller 101 and ensure the heat exchange effect, in this solution, the gear ratio of the first gear 118 and the second gear 119 is equal, and the gear ratio of the third gear 120 and the internal gear 116 is 1:1-6, and the preferred gear ratio is 1:6.

[0052] The present invention also discloses a cloth rolling machine, which uses the above cloth rolling roller, and also includes two side plates, three laterally distributed cloth guide rollers 2, a tension roller 4, a driving roller 3 and a supporting roller 5. A guide plate 6 is fixed on the side of the side plate, and a guide groove is formed in the middle of the guide plate 6, such as Figure 2 As shown, the guide groove passes through the top plate body of the guide plate 6, so that the top of the guide plate 6 is in an open state and the bottom of the guide plate 6 is in a closed state, so that the cloth winding roller can be placed and taken out. It can be known that the center line of the guide groove is perpendicular to the connecting line between the central axis of the driving roller 3 and the supporting roller 5. In this way, when the driving roller 3 rotates continuously, the supporting roller 5 supports the driving roller 3, and as the cloth is continuously wound, the driving roller 3 moves along the guide groove.

[0053] In the winder, the cloth guide roller 2 in the middle and the cloth guide rollers 2 on both sides can be connected by gear meshing, the driving roller 3 is driven by the magnetic powder motor, and the driving roller 3 and the supporting roller 5 and the driving roller 3 and the cloth guide roller 2 can be connected by a chain (belt), such as Figure 1 As shown, the cloth guide roller 2 guides the cloth, the support roller 5 supports the cloth winding roller and the drive roller 3 drives the cloth winding roller, so that the cloth winding roller finally winds up the cloth. In addition, a tension sensor is provided on the tension roller 4, and the tension of the cloth is detected by the tension sensor. The detected data is transmitted to the central control system of the cloth winding machine. The central control system adjusts the driving force of the magnetic powder motor according to the tension change, so that the tension of the cloth is kept consistent when winding. The above is the prior art, and specific reference is made to the existing patents, such as a hydraulic cloth unloading automatic winding high-foot cloth winding machine disclosed in the authorization number "CN217516365U", and a new type of cloth winding roller disclosed in the authorization number "CN211971384U".

[0054] A gap is formed between the end of the movable block 107 and the bottom wall of the guide groove. Under the action of the induced air fan 110, the outside air enters the inner cavity of the roller 101 through the gap, the induced air hole 115 and the connecting hole 114, and then enters the ventilation groove 102 through the air outlet 103. There may be large particles of dust in the outside air. If these dusts enter the cavity of the roller 101, they may block the air outlet 103. Therefore, in another specific embodiment of the present scheme, as shown in FIG. Figure 6 As shown, a filter is detachably fixed at the end of the movable block 107. The detachable fixing method can be a magnetic fixing method or a screw connection method. When the outside air enters the inner cavity of the roller 101, the introduced air is filtered through the filter. In this way, it is only necessary to regularly adjust the filter, which makes it convenient to use the cloth rolling roller and improves the practicality of the cloth rolling roller.

[0055] In order to prevent the cloth rolling roller from moving laterally when the cloth is rolled up, in the present solution, tracks 601 are provided on the guide plates 6 located on both sides of the guide groove, so that the movable block 107 can only move along the track 601. In a specific embodiment of the present solution, since a movable wheel 108 is provided, the movable wheel 108 can also be movably set in the track 601.

[0056] In addition, in order to make it easier for external air to enter the inner cavity of the roller 101 through the air inlet holes 115, Figure 1 As shown, a side groove 7 connected to the guide groove is provided on the side plate of the cloth winding machine.

[0057] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is limited by the attached embodiments and their equivalents.
