Description

Technical Field

[0001] The invention relates to the technical field of cloth processing, and in particular to a cloth finishing roller. Background Art

[0002] Winding equipment is widely used in fabric processing. It primarily utilizes a winding roller to wind fabric into rolls for subsequent processing, transportation, and storage. During the winding process, the winding roller typically passes the end of the fabric over various guide rollers and secures it to the roller body, continuously winding the fabric as it rotates. However, due to various factors interfering with the actual winding process, wrinkles can form during the fabric winding process. These wrinkles not only affect the fabric's appearance but also adversely affect subsequent processing. Therefore, eliminating these wrinkles has become a significant challenge in this field. Currently, a common approach involves adjusting the fabric tension using tension-adjusting rollers to reduce wrinkling. For existing wrinkles, manual work is performed to smooth them out. However, this approach requires bedside assistance, resulting in a low level of automation and requiring significant monitoring.

[0003] In theory, to eliminate wrinkles in fabric, it is actually necessary to apply a lateral flattening force to the wrinkled area while ensuring that the overall tension of the fabric is appropriate, so as to stretch the wrinkled area. Therefore, to achieve the ideal effect of anti-wrinkle winding, there are two core elements. One is to facilitate efficient and accurate control of the tension at the input and output ends of the fabric, and the other is to quickly flatten the fabric horizontally to eliminate wrinkled areas. From the first point of view of tension control, when existing equipment adjusts the tension, it mainly adjusts the contact tightness of the pressure regulating roller with the fabric through the overall swinging rotation, thereby achieving pressure regulation. This swinging pressure regulation method has extremely high requirements for the control of the swing angle of the pressure regulating roller, and is prone to inaccurate pressure regulation. From the second point of view of lateral flattening, the relevant technology has not yet been reported. Summary of the Invention

[0004] The object of the present invention is to provide a cloth finishing roller having both feeding and transferring performances.

[0005] To achieve the above-mentioned object, the technical solution adopted by the present invention is as follows: a cloth finishing roller, comprising a roller shaft and a roller drum, wherein the roller shaft comprises a coupling section, a bending section, and a supporting section in sequence; the coupling section of the roller shaft is passed through a bearing on a mounting plate and forms a rotational fit with the mounting plate; the roller drum is mounted on the supporting section of the roller shaft and forms a rotational fit with the supporting section;

[0006] The roller shaft can rotate during the conveying of the cloth, and the roller on the roller shaft rotates eccentrically around the connecting shaft section to form intermittent downward pushing of the cloth; the roller can rotate when the cloth is pushed down, and provide a lateral component of force along the width direction of the cloth to the cloth through the rotational contact between the roller surface and the cloth, so as to form flattening of wrinkles on the cloth.

[0007] Preferably, the roller rotates passively, and the roller rotates passively through friction with the cloth.

[0008] Preferably, the roller is actively rotated, and the roller is driven by a roller driving assembly to form active rotation.

[0009] Preferably, the roller drive assembly includes a friction cylinder fixedly mounted on the outer side of the mounting plate, the friction cylinder being coaxially arranged with the coupling section of the roller shaft, and the inner ends of the bending section and the supporting section of the roller shaft being located within the friction cylinder; a friction disk for forming friction with the inner side wall of the friction cylinder is provided on the end surface of the roller near one end of the bending section of the roller shaft;

[0010] During the rotation of the coupling section of the roller shaft, the roller is driven to rotate by the friction force between the friction disk and the inner wall of the friction cylinder.

[0011] Preferably, an antistatic coating is sprayed on the outer side wall of the roller.

[0012] Preferably, a rubber layer for increasing friction is provided on the inner wall of the friction cylinder and the outer wall of the friction disc.

[0013] The beneficial effects of the present invention are mainly reflected in the following aspects: since the finishing roller has both the intermittent downward pushing and horizontal rotation and flattening transmission performance, it has the function of elastic pulling in the process of flattening the fabric, and has a better wrinkle removal effect. Specifically, during use, the finishing roller of the present invention drives the roller shaft to rotate as a whole through the connecting shaft section of the roller shaft. Due to the existence of the roller shaft bending section, the roller shaft support section forms an eccentric rotation, and then the roller installed thereon can form an intermittent downward pushing on the fabric, thereby achieving the elasticity of the fabric; at the same time, since the roller can rotate relative to the support roller section, the roller can apply a horizontal component force along the width direction of the fabric to the fabric during the rotation process, thereby achieving the flattening of wrinkles during the rotation process, and combined with the elasticity of the finishing roller on the fabric as a whole, the wrinkle elimination effect is excellent, especially for long wrinkles.

[0021] like Figure 1-7 As shown, a cloth winding device is used to wind the banner cloth that has been processed in the previous sequence into a cloth roll. The winding is mainly carried out on the winding roller 3. In order to cooperate with the winding roller 3, the present invention includes a feed roller 1 and a discharge roller 2 arranged side by side. The feed roller 1 is used to introduce the cloth that has been processed in the previous sequence into the device in preparation for leveling, and the discharge roller 2 is used to lead out the leveled cloth in preparation for winding. The winding roller 3 is located on one side of the discharge roller 2.

[0022] The first bottom roller 4 and the second bottom roller 5 are respectively provided on one side below the feed guide roller and the discharge guide roller. Figure 1 As shown in the figure, the first bottom roller 4 and the second bottom roller 5 are arranged in an eight-shaped shape relative to the feed roller 1 and the discharge roller 2. The first bottom roller 4 and the second bottom roller 5 play a role in guiding the cloth, and a working area for leveling the cloth is formed between the two. The cloth passes through the feed roller 1, the first bottom roller 4, the second bottom roller 5, and the discharge roller 2 in sequence, and the rear end is wound on the winding roller 3.

[0023] The present invention smoothes wrinkles on the fabric between the first bottom roller 4 and the second bottom roller 5, thereby eliminating wrinkles on the fabric. It also coordinates with adjusting the fabric tension between the first bottom roller 4 and the feed roller 1 to reduce the rate of wrinkles on the fabric entering the winding device. It also coordinates with adjusting the fabric tension between the second bottom roller 5 and the discharge roller 2 to prevent wrinkles from reappearing after smoothing.

[0024] From the perspective of flattening the cloth between the first bottom roller 4 and the second bottom roller 5, a finishing mechanism 6 for flattening the wrinkles on the cloth is provided above the cloth between the first bottom roller 4 and the second bottom roller 5. Figure 1 and 2 As shown in FIG, the arranging mechanism 6 of the present invention includes a base plate 7, as shown in FIG. Figure 2As shown in the figure, two groups of sorting rollers 8 are provided on the bottom surface of the substrate 7. The two groups of sorting rollers 8 are arranged in an eight-shaped shape, and the opening direction of the eight-shaped shape is the same as the conveying direction of the fabric. The sorting roller 8 is generally a linear rotating roller that can rotate around the axis.

[0025] like Figure 2 As shown in FIG, the conveying direction of the cloth is from right to left, from the first bottom roller 4 to the second bottom roller 5, and the opening direction of the larger side of the eight-shaped two sets of finishing rollers is also facing left. Each of the finishing rollers 8 is tilted backward from the inner end to the outer end toward the side close to the first bottom roller 4, as shown in FIG. Figure 2 Take the top finishing roller 8 as an example: it is tilted from the bottom to the top. Generally, the tilt angle is between 10-30 degrees. If the tilt angle is too large, the coverage of the single finishing roller 8 in the width direction of the fabric will be too small. If the tilt angle is too small, the lateral force it can provide will be too small. The ideal value is around 20 degrees.

[0026] During finishing operations, the finishing rollers 8 rotate in the same direction as the fabric is being fed. This ensures both the fabric is conveyed and a lateral force component. It's important to note that the number of finishing rollers 8 in each group should be sufficient to achieve a smoothing range that covers the entire width of the fabric. As shown in the figure, each group of finishing rollers 8 includes three finishing rollers. In practice, four, five, or other finishing rollers may be used, depending on the length of each individual finishing roller. However, each group should contain at least two finishing rollers.

[0027] The finishing rollers 8 described in the present invention are capable of rotating during fabric conveyance and, through rotational contact with the fabric, provide a lateral force component along the fabric's width, thereby flattening wrinkles in the fabric. During use of the finishing mechanism of the present invention, the fabric passes sequentially through the feed roller 1, the first bottom roller 4, the second bottom roller 5, and the discharge roller 2 before being wound up on the winding roller 3. As the fabric passes through the area between the first bottom roller 4 and the second bottom roller 5, it comes into contact with the finishing rollers 8 of the finishing mechanism. Under the segmented finishing action of the two sets of finishing rollers 8, wrinkles across the entire width of the fabric are flattened to both sides, ensuring their elimination. Because the present invention flattens the fabric from the inside out across its width during wrinkle finishing, it effectively reduces the recurrence of wrinkles, ensuring the stability and comprehensiveness of the finishing quality.

[0028] The finishing roller 8 of the present invention can be a driven roller, passively rotating due to friction with the fabric. That is, the fabric moves under the winding force of the winding roller 3, while the rotation of the finishing roller 8 is caused by friction with the fabric. Of course, to enhance the finishing effect, a further preferred embodiment of the present invention is that the finishing roller 8 is an active roller, actively rotating due to a finishing drive assembly. This active rotation provides an active lateral force component for lateral flattening of the fabric.

[0029] The finishing rollers 8 can be actively driven in a variety of ways, meaning that the specific structure of the finishing drive assembly varies. For example, they can be independent micromotors fitted to the drive ends of the finishing rollers 8. By controlling the start and stop and speed of each micromotor, the finishing rollers 8 rotate in coordination. However, since the present invention utilizes two sets of multiple finishing rollers 8 for finishing, to reduce equipment costs and ease control, a more practical approach is to utilize a finishing drive assembly with a single power source.

[0030] When a finishing drive assembly with a single power source is used for driving, a vertical mounting plate 9 is generally provided at a position opposite to the inner end of the finishing roller 8 on the bottom surface of the base plate 7. The finishing roller 8 is provided on the mounting plate 9 and rotates in conjunction with the mounting plate 9. The finishing drive assembly includes a plurality of intermediate shafts 10 provided between two opposite finishing rollers 8 in the two groups of finishing rollers 8. The two ends of each intermediate shaft 10 are respectively connected to the roller shaft 15 of the corresponding finishing roller 8 through a coupling 11. A driving worm gear 12 is provided in the middle of each intermediate shaft 10, and a plurality of the driving worm gears 12 are distributed in a straight line along the length direction of the base plate 7. By driving each driving worm gear 12 to rotate, a plurality of intermediate shafts 10 can be driven to rotate synchronously, thereby driving the finishing roller 8 to rotate synchronously. In order to synchronously drive the driving worm gears 12 on the plurality of intermediate shafts 10, such as Figure 2 As shown in , the finishing drive assembly further includes a drive worm 13 disposed in the middle of the base plate 7 and extending along the length direction of the base plate 7, and the drive worm 13 is engaged with the drive worm wheel 12. One end of the drive worm 13 is in transmission connection with a leveling motor 14 fixedly disposed on the base plate 7.

[0031] Generally, the finishing roller 8 applicable to the present invention can be a simple, linear rotating roller, which performs the smoothing operation simply through the rotation of the roller body. This type of finishing roller 8 is suitable for most fabrics. However, because wrinkles on fabrics can sometimes be long and extend into corners, corresponding to the first and second bottom rollers 4 and 5, where the fabric tension is high, the simple rotation of the finishing roller 8 is insufficient to completely smooth out wrinkles on some highly elastic fabrics. Therefore, it is often necessary to pluck the fabric up and down while the finishing roller 8 rotates to eliminate excessively long wrinkles.

[0032] To this end, the present invention also discloses a special finishing roller 8, which has both the performance of transfer and dialing. Figure 3 and 4 As shown in FIG, the finishing roller 8 includes a roller shaft 15 and a roller drum 16. The roller shaft 15 sequentially comprises a coupling section 17, a bent section 18, and a support section 19. The coupling section 17 is used for connection to a power source, and the support section 19 is used to mount the roller 16. The bent section 18 connects the coupling section 17 and the support section 19, forming a corner between them. In other words, the coupling section 17 and the support section 19 are not aligned with each other. The coupling section 17 of the roller shaft 15 is mounted on the mounting plate 9 via a bearing 0 and forms a rotational engagement with the mounting plate 9. The roller 16 is mounted on the support section 19 of the roller shaft 15 and forms a rotational engagement with the support section 19.

[0033] When this dual-function finishing roller 8 is used, the roller shaft 15 can rotate during fabric conveyance, and the roller 16 on the roller shaft 15 rotates eccentrically about the coupling section 17 to provide intermittent support for the fabric. The roller 16 can rotate during the fabric support, and the rotational contact between the roller 16 surface and the fabric provides a lateral force component along the fabric width, thereby smoothing out wrinkles in the fabric.

[0034] During use, the finishing roller 8 drives the roller shaft 15 to rotate as a whole through the connecting shaft section 17 of the roller shaft. Due to the existence of the bent section 18 of the roller shaft 15, the supporting section 19 of the roller shaft 15 rotates eccentrically, so that the roller 16 installed thereon can form an intermittent downward push on the cloth, thereby realizing the elasticity of the cloth; at the same time, since the roller 16 can rotate relative to the supporting roller section 19, the roller 16 can apply a lateral component of force along the width direction of the cloth to the cloth during the rotation process, thereby realizing the flattening of wrinkles during the rotation process, and combined with the overall elasticity of the cloth by the finishing roller 8, the wrinkle elimination effect is excellent, especially the elimination rate of long wrinkles is excellent.

[0035] The roller 16 of the present invention can be driven in two ways during its rotation. In one case, the roller 16 rotates passively, driven by friction with the fabric. In this case, the roller 15 is actively driven by power input from the coupling 17, while the roller 16 is driven by friction generated by the fabric during contact with the fabric. In another case, the roller 16 is also actively driven. That is, the roller 15 is actively driven by power input from the coupling 17, while the roller 16 is driven by power input from a drive assembly or other prime mover. In this second case, the present invention can utilize the following preferred method to drive the roller 16 through power input from the coupling 17 (i.e., the power input from the coupling 17 simultaneously drives the roller 15 and the roller 16 to actively rotate).

[0036] Combine Figure 3 and 4 As shown in , the roller drive assembly includes a friction cylinder 20 fixedly mounted on the outer side of the mounting plate 9. The friction cylinder 20 is coaxially arranged with the coupling section 17 of the roller shaft 15. The inner ends of the bent section 18 and the supporting section 19 of the roller shaft 15 are both located within the friction cylinder 20. A friction disk 21 is provided on the end surface of the roller 16 near the bent section 18 of the roller shaft 15, which is used to rub against the inner sidewall of the friction cylinder 20. When the coupling section 17 of the roller shaft 15 rotates, the roller 16 is driven to rotate by the friction force between the friction disk 21 and the inner sidewall of the friction cylinder 20.

[0037] In this configuration, when the driving force is input from the coupling section 17, it drives the coupling section 17, the bending section 16, and the support section 19 (that is, the entire roller shaft 15) to rotate, achieving intermittent lowering. At the same time, due to the continuous friction between the friction disc 21 and the friction cylinder 20, it can drive the friction disc 21 to rotate, and then through the friction disc 21, it drives the roller 16 connected to it to rotate. This achieves the intermittent lowering and transfer functions synchronously. In order to increase the friction force and ensure the stability of the transfer function, as shown in the following figure, Figure 4 As shown in FIG, a rubber layer 22 for increasing friction is provided on the inner wall of the friction cylinder 20 and the outer wall of the friction disc 21 .

[0038] Of course, considering that the roller 16 needs to have friction when in contact with the cloth, and friction will generate a certain amount of static electricity, in order to eliminate the adverse effects of static electricity, the present invention should also have a static elimination function, for example: the outer wall of the roller 16 is sprayed with an anti-static coating.

[0039] The finishing roller 8 disclosed in the present invention can be used in combination with the finishing mechanism of the present invention, or can be adapted separately and used in other cloth finishing work units for eliminating the cloth winding cycle.

[0040] In addition, with regard to adjusting the fabric tension between the first bottom roller 4 and the feed roller 1, and adjusting the tension between the second bottom roller 5 and the discharge roller 2, the present invention also provides a group of tension adjustment mechanisms 23 for adjusting the fabric tension between the feed roller 1 and the first bottom roller 4, and between the discharge roller 2 and the second bottom roller 5.

[0041] Combine Figure 1 、 5 -7. The tension adjustment mechanism 23 includes a square frame-shaped tension adjustment frame 24, with vertical guide side holes 25 provided on both side walls of the tension adjustment frame 24. Two horizontally extending lifting cross bars 26 are provided in the middle of the tension adjustment frame 24. The ends of the lifting cross bars 26 pass through the guide side holes 25 and form a vertical sliding fit with the two side walls of the tension adjustment frame 24.

[0042] In order to ensure the stability of the movement of the lifting crossbar 26 in the guide side hole 25, and at the same time limit the position of the guide crossbar 26 in the length direction, as shown in FIG. Figure 7 As shown in FIG, the cross-section of the guide hole 25 is shaped like a trumpet, with the inner portion larger and the outer portion smaller. A guide head 31 is provided at the end of the lifting crossbar 26 to mate with the guide hole 25. The guide head 31 is inserted into the guide hole 25 to provide an upward and downward guide. This trumpet-shaped structure effectively prevents lateral movement of the lifting crossbar 26, ensuring its lifting stability.

[0043] The lifting crossbar 26 is driven by a lifting drive assembly, which may be a cylinder, a linear telescopic motor, etc. Figure 5 As shown in FIG, the lifting drive assembly includes a tension adjustment motor 29 fixedly mounted on the top of the tension adjustment frame 24. A vertical adjustment screw 30 is provided in the tension adjustment frame 24. The adjustment screw 30 is rotationally engaged with the tension adjustment frame 24 and is in transmission connection with the tension adjustment motor 29. The lifting crossbar 26 is provided with a screw hole that cooperates with the tension adjustment screw 30. The tension adjustment screw 30 is inserted into the screw hole and forms a threaded engagement with the lifting crossbar 26.

[0044] The tension adjustment roller 28 of the present invention is installed on the lifting crossbar 26, and its upper and lower positions are adjusted by the lifting and lowering of the lifting crossbar 26. Figure 1As shown in the figure, the lifting cross bar 26 is connected by two V-shaped connecting arms 27 near the two ends, and a tension adjustment roller 28 for contacting the cloth is provided between the V-shaped tips of the two connecting arms 27. The tension adjustment mechanism 23 drives the tension adjustment roller 28 to move up and down through the lifting cross bar 26 to adjust the tension of the cloth.

[0045] During use, the present invention drives the connecting arm 27 by the lifting crossbar 26, which in turn drives the tension-adjusting roller 28 to move up and down. As the tension-adjusting roller 28 moves up and down, the varying tensile strengths exerted on the fabric by the tension-adjusting roller 28 enable rapid tension adjustment. This invention abandons the traditional method of adjusting tension by swinging the tension-adjusting roller 28, transforming the angle control used in swinging adjustment into distance control used in lifting adjustment. This results in higher control precision and greater control convenience. Furthermore, because the tension-adjusting roller 28 is supported by the V-shaped connecting arm 27, it offers greater stability compared to single- or double-cross-arm arrangements.

[0046] There are usually two groups of tension adjustment mechanisms, one for adjusting the tension of the fabric between the feed roller 1 and the first bottom roller 4, and the other for adjusting the tension of the fabric between the discharge roller 2 and the second bottom roller 5. Each of them can use a tension adjustment frame 24, or they can share a tension adjustment frame 24.
