Description

Technical Field

[0001] The invention relates to the technical field of textiles, and in particular to a cloth-roller-detachable unwinding bracket mechanism and a cloth-inspecting machine. Background Art

[0002] In modern textile, printing and dyeing and related industries, the cloth roller unwinding bracket is a key device for supporting and conveying cloth. Its main function is to ensure that the cloth can be smoothly unwound from the cloth roller by providing stable support for subsequent processing, testing or finishing. However, the existing traditional unwinding brackets are usually simple in structure, and most of them adopt a fixed design, which has certain operational limitations. Especially when the cloth roller needs to be replaced, the disassembly process of traditional equipment is relatively cumbersome, usually requiring the disassembly of multiple parts, which is complicated and time-consuming, significantly reducing production efficiency.

[0003] The traditional unwinding bracket often requires tools or the cooperation of multiple people to dismantle and replace the cloth roll, which not only increases the difficulty of operation, but also increases the safety hazard. Especially when it is necessary to frequently replace cloths of different specifications and materials, the inconvenience of disassembly may cause equipment damage or cloth waste. In addition, due to the lack of design flexibility, the traditional unwinding bracket cannot meet the market changes in the demand for rapid disassembly, replacement and adjustment of different cloth rolls, resulting in long production line downtime and affecting the production rhythm.

[0004] In the prior art, there have been some studies on improving the efficiency of cloth roll switching, such as the cloth roll fixing device for printing and dyeing fabrics disclosed in Chinese patent announcement CN107902453B. The device realizes the assembly and disassembly of the cloth roll by synchronously pushing multiple sets of clamps to open and close through a push block. Although it improves the disassembly speed to a certain extent, its design still has limitations. The device can only limit the cloth roll of fixed size and specification, and the clamp has a long fixing time. It is necessary to use a correction device to adjust the cloth roll to a coaxial state with the clamp, so the flexibility and versatility still need to be improved.

[0005] In addition, most of the existing unwinding brackets do not perform well in adjusting the tension of the fabric. Fabric tension directly affects the accuracy of subsequent processing and testing. If it cannot be accurately adjusted according to the actual situation of the fabric, it may cause the fabric to be loose or too tight, thus affecting product quality. Many traditional unwinding brackets do not provide sufficient tension adjustment functions, or their adjustment methods are too single and cannot meet the requirements of different production environments, limiting the applicability of the equipment in different production processes. Summary of the invention

DETAILED DESCRIPTION

[0034] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0035] See also Figures 1 to 10 As shown: A cloth roll detachable unwinding bracket mechanism for supporting a cloth roll, comprising: a base frame 1; a guide module 2, wherein the guide module 2 is provided with two groups, and the two groups of the guide modules 2 are fixedly arranged on the top of the base frame 1 in a horizontal state; and the two groups of the guide modules 2 are provided with a first guide channel 21, a second guide channel 22 and a third guide channel 23 respectively connected to the first guide channel 21 and the second guide channel 22; an elastic clamping module 3, wherein the elastic clamping module 3 is provided with two groups, and the two groups of the elastic clamping modules 3 are respectively fixedly arranged on the two groups The elastic clamping module 3 is on the guide module 2 and is arranged at the third guide channel 23. The elastic clamping module 3 is provided with a fixed clamping unit 31 and a movable clamping unit 32 that can move toward each other; the axial limiting module 4, the axial limiting module 4 is provided with two groups, and the two groups of axial limiting modules 4 are respectively fixedly arranged on the outer side of the base frame 1 in parallel along the long side direction of the base frame 1; the driving module 5, the driving module 5 is fixedly arranged on the top of the guide module 2; the tensioning module 6, the tensioning module 6 is horizontally arranged between the two groups of guide modules 2 through the first mounting frame 61.

[0036] In a non-working state, at least two groups of cloth rolling rollers are provided, and the two groups of cloth rolling rollers are respectively arranged across the first guide channel 21 and the second guide channel 22 of the two groups of guide modules 2 .

[0037] When the cloth roller needs to be installed quickly, firstly, two sets of cloth rollers are hoisted into the first guide channel 21 and the second guide channel 22 respectively by external hoisting equipment; then the cloth roller located in the first guide channel 21 is driven to move, so that it slides along the guide track of the first guide channel 21 until the cloth roller slides into the third guide channel 23. During the sliding process, the cloth roller pushes away the fixed clamping unit 31 and the movable clamping unit 32 that are close to each other in the non-working state through the force of its own sliding, so that the fixed clamping unit 31 and the movable clamping unit 32 move away from each other, thereby providing space for the cloth roller to enter the clamping area. When the cloth roller enters between the fixed clamping unit 31 and the movable clamping unit 32, its end is clamped by the fixed clamping unit 31, and the fixed position is locked; at the same time, the movable clamping unit 32 will also reset under the action of its own elastic force, and approach the fixed clamping unit 31 again, forming a stable elastic clamping for the cloth roller, and completing the rapid installation of the cloth roller.

[0038] In order to ensure that the cloth roller clamped by the elastic clamping module 3 can remain in the centered state, the axial limit module 4 is driven to act, and the two ends of the cloth roller are axially adjusted through the axial limit module 4, so that the current cloth roller is always centered between the two sets of guide modules 2. Finally, when it is necessary to drive the cloth roller to rotate, it is only necessary to connect the driving end of the driving module 5 to the driving shaft of the cloth roller, and the power output by the driving module 5 can realize the efficient rotation of the cloth roller.

[0039] By providing the guide module 2, the fixed clamping unit 31, the movable clamping unit 32 and the axial limit module 4, the cloth rolling roller can be quickly installed and positioned, thus avoiding the inefficiency of the traditional method of relying on manual or external auxiliary equipment for complex adjustments; at the same time, through the coordinated action of the elastic clamping module 3 and the axial limit module 4, the cloth rolling roller is ensured to always maintain a stable centered state during the clamping and transmission process, thereby significantly improving the reliability and applicability of the equipment operation.

[0040] The driving module 5 includes a third mounting frame 51, a servo motor 52, a driving wheel 53, a second slider 54, a tensioning wheel 55, a transmission belt 56 and a second electric push rod 57; the servo motor 52 is horizontally fixedly arranged on the top of the guide module 2 through the third mounting frame 51; the driving wheel 53 is coaxially fixedly arranged on the driving end of the servo motor 52; the third slide groove 46 is horizontally penetrated and opened on the third mounting frame 51; the tensioning wheel 55 is slidably arranged in the third slide groove 46 through the second slider 54; the second electric push rod 57 is horizontally fixedly arranged on one side of the third mounting frame 51 and the output shaft is fixedly connected to the second slider 54; the transmission belt 56 is used to transmit and connect the driving wheel 53 and the rotating shaft of the cloth winding roller, and the tensioning wheel 55 is used to automatically adjust the tensioning force of the synchronous belt according to the rotating shaft of the cloth winding roller with different diameters, so as to maintain it in a normal transmission posture.

[0041] See also Figure 7 and Fig. 9As shown: the guide module 2 includes a connecting frame 24 and a guide frame 25; the guide frame 25 is horizontally fixed on one side of the top of the base frame 1 through the connecting frame 24; the guide frame 25 is a rectangular plate with a Y-shaped structure, and the first guide channel 21, the second guide channel 22 and the third guide channel 23 are opened on the rectangular plate, and the first guide channel 21, the second guide channel 22 and the third guide channel 23 are arranged in a Y shape; the first guide channel 21 and the second guide channel 22 are respectively located on both sides of the guide frame 25 and are independent of each other, and the first guide channel 21 and the second guide channel 22 are further provided with a bayonet 26 matching the rotating shaft of the cloth rolling roller at one end away from the third guide channel 23, and the bayonet 26 is used to limit the cloth rolling roller before it slides into the guide channel; the third guide channel 23 is arranged at the intersection with the first guide channel 21 and the second guide channel 22, constituting a sliding path for the cloth rolling roller from the feeding area to the fixed area.

[0042] The bayonet 26 is V-shaped and opened at the entrance end of the first guide channel 21 and the second guide channel 22, and is used to initially clamp the cloth rolling roller carried in the first guide channel 21 and the second guide channel 22. Since the first guide channel 21, the second guide channel 22 and the third guide channel 23 are Y-shaped and opened on the guide frame 25, the cloth rolling roller can slide quickly along the guide track to the third guide channel 23 no matter it is located in the first guide channel 21 or the second guide channel 22, and the cloth rolling roller can be quickly limited and clamped by the elastic clamping module 3 arranged in the third guide channel 23; when it is necessary to take the cloth rolling roller out of the third guide channel 23, it only needs to be driven again to slide along the original path to the first guide channel 21 or the second guide channel 22 and be pushed out to complete the disassembly operation.

[0043] See also Figure 5 and Figure 7 As shown: the elastic clamping module 3 also includes a first fixed frame 33, a slide rail 34 and a first guide rod 35 that can synchronously limit and guide the rear ends of the fixed clamping unit 31 and the movable clamping unit 32; two first guide rods 35 are provided, and the two first guide rods 35 are symmetrically arranged in a vertical state on the side of the guide module 2 close to the cloth winding roller through the first fixed frame 33; the fixed clamping unit 31 and the movable clamping unit 32 are relatively arranged in the middle of the first guide rod 35, and the rear ends are respectively passed through the first guide rod 35 and slidably cooperate with the first guide rod 35; the slide rail 34 is fixedly arranged in a vertical state on the side of the guide module 2 close to the cloth winding roller, and the slide rail 34 is used to guide the front ends of the fixed clamping unit 31 and the movable clamping unit 32 respectively.

[0044] The first guide rod 35 and the slide rail 34 are used to guide the fixed clamping unit 31 and the movable clamping unit 32, which are driven by the cloth winding roller to move away from each other, to slide only along the guiding direction of the two first guide rods 35 and the slide rail 34, so that the fixed clamping unit 31 and the movable clamping unit 32 only have axial freedom and cannot rotate at will, thereby realizing the axial free sliding restriction of the fixed clamping unit 31 and the movable clamping unit 32, thereby effectively avoiding the deviation and rotation phenomena generated during their movement, and ensuring the positioning accuracy and clamping stability of the cloth winding roller during installation and operation.

[0045] See also Figure 5 , Figure 7 and Figure 8 As shown in the figure: the fixed clamping unit 31 includes a first clamping plate 311, a first slide groove 312, a second guide rod 313, a fixed seat 314, an adjusting knob 315 and a first rolling limit element 316; the first clamping plate 311 is horizontally arranged between the first guide rod 35 and the slide rail 34, and the rear end of the first clamping plate 311 passes through the two first guide rods 35 and is slidably matched with the two first guide rods 35; the first slide groove 312 is opened at the front end of the first clamping plate 311 and is arranged on a side close to the guide module 2, and the first clamping plate 311 is arranged between the first guide rod 35 and the slide rail 34. The front end of 11 is slidably matched with the slide rail 34 through the first slide groove 312; the second guide rod 313 is vertically arranged on the lower surface of the first clamping plate 311, and the rod part of the second guide rod 313 passes through the fixed seat 314 vertically fixed on the inner side of the guide module 2 and slidably matches with the fixed seat 314; there are two adjusting knobs 315, and the two adjusting knobs 315 are respectively screwed on the first guide rod 35 and the second guide rod 313; the first rolling limiting element 316 is embedded in the upper surface of the first clamping plate 311.

[0046] The fixing seat 314 is vertically fixedly disposed on a side of the guide frame 25 close to the cloth rolling roller.

[0047] When the support height of the first clamping plate 311 needs to be adjusted according to the roller diameter of the current cloth rolling roller, the staff only needs to rotate and adjust the position of the adjustment knob 315 to move it to a predetermined position along the second guide rod 313. The adjustment knob 315 can effectively limit the lowest descending position of the first clamping plate 311 through the linkage setting with the first clamping plate 311, thereby changing its support height. By accurately setting the position of the adjustment knob 315, the support height of the first clamping plate 311 can be flexibly adjusted to meet the clamping requirements of cloth rolling rollers with different diameters.

[0048] See also Fig. 9As shown: the first clamping plate 311 is composed of a horizontal plate 3111, a V-shaped plate 3112 and a guide plate 3113 which are connected in sequence; a through hole is also penetrated through the upper surface of the horizontal plate 3111, and the horizontal plate 3111 is slidably matched with the first guide rod 35 through the through hole; the V-shaped plate 3112 is horizontally fixedly arranged at one end of the horizontal plate 3111 and the opening of the V-shaped plate 3112 is arranged upward, and the first rolling limiting element 316 is embedded in the V-shaped plate 3112; the guide plate 3113 is fixedly arranged in an inclined state at one end of the V-shaped plate 3112 away from the horizontal plate 3111, and the guide plate 3113 is inclined toward the tip side of the V-shaped plate 3112, and the angle between the guide plate 3113 and the V-shaped plate 3112 is an obtuse angle.

[0049] The first sliding groove 312 is formed on a side of the guide plate 3113 close to the guide module 2 and is slidably matched with the slide rail 34 .

[0050] Since the guide plate 3113 is fixedly arranged in an inclined state at one end of the V-shaped plate 3112 away from the horizontal plate 3111, and the guide plate 3113 is inclined toward the tip of the V-shaped plate 3112 and forms an obtuse angle with the V-shaped plate 3112, when the cloth rolling roller is conducted into the third guide channel 23, the roller of the cloth rolling roller will contact the inclined surface of the guide plate 3113, and will crawl along the inclined surface of the guide plate 3113 during the continuous forward movement until the roller is embedded in the V-shaped plate 3112, and finally it is limited by the first rolling limiting element 316 embedded in the V-shaped plate 3112, thereby achieving the purpose of embedding the cloth rolling roller.

[0051] See also Fig. 9 As shown: the first rolling limiting element 316 includes a second fixed frame 3161 and a limiting roller 3162; two second fixed frames 3161 are provided, and the two second fixed frames 3161 are symmetrically arranged in the V-shaped plate 3112 along the long side direction of the first clamping plate 311 and are respectively arranged close to the two sides of the V-shaped plate 3112; the limiting roller 3162 is provided in multiple groups, and the multiple groups of limiting rollers 3162 are rotatably arranged across the two second fixed frames 3161.

[0052] When the cloth rolling roller slides into the V-shaped plate 3112 under the driving action and is fixed by the first rolling limit element 316 embedded in the V-shaped plate 3112, the rotating shaft of the cloth roller will first contact the surface of the plurality of limit rollers 3162. At the same time, since the two second fixing frames 3161 are arranged in a V-shaped structure, when the rotating shaft of the cloth roller is locked by the second fixing frames 3161 and the limit rollers 3162, it can be automatically adjusted to abut against the surface of the limit rollers 3162 adapted thereto according to the diameter of the rotating shaft, thereby providing support to the cloth roller through the limit rollers 3162, while retaining the axial degree of freedom in the locked state.

[0053] Through the structural cooperation between the V-shaped plate 3112 and the first rolling limit element 316, combined with the V-shaped setting of the second fixed frame 3161 and the elastic adaptation of multiple sets of limit rollers 3162, not only the installation process of the cloth roller is simplified, but also the precise clamping and adaptive adjustment of the rotating shaft are achieved, ensuring that the cloth rolling roller retains axial freedom in a fixed state, thereby improving the operating stability of the cloth roller and the overall operational flexibility of the equipment.

[0054] See also Figure 7 and Figure 8 As shown in the figure: the movable clamping unit 32 includes a second clamping plate 321, a second slide groove 322, a supporting spring 323 and a second rolling limit element 324; the second clamping plate 321 and the first clamping plate 311 have the same structure, the second clamping plate 321 is arranged between the first guide rod 35 and the slide rail 34 in a horizontal state relative to the first clamping plate 311, and the rear end of the second clamping plate 321 is slidably matched with the first guide rod 35; the second slide groove 322 is opened at the front end of the second clamping plate 321 and is arranged on a side close to the guide module 2; the second The front ends of the two clamping plates 321 are slidably matched with the slide rail 34 through the second slide groove 322; two support springs 323 are provided, and the two support springs 323 are coaxially sleeved and installed outside the two first guide rods 35; and one end of the support spring 323 abuts against the first fixed frame 33, and the other end of the support spring 323 abuts against the upper surface of the second clamping plate 321; the second rolling limit element 324 is embedded in the lower surface of the second clamping plate 321, and the second rolling limit element 324 has the same structure as the first rolling limit element 316.

[0055] When the cloth roller is conducted into the third guide channel 23, its roller will contact the inclined surface of the guide plate 3113 in the first clamping plate 311 and the second clamping plate 321 respectively, and climb along the inclined surface of the guide plate 3113 during the continuous sliding process, thereby pushing away the second clamping plate 321 that can move along the axis of the first guide rod 35, making it temporarily away from the first clamping plate 311 and forming a gap for the shaft to enter. When the shaft of the cloth roller is clamped in the first clamping plate 311, due to the loss of the lifting force from the cloth roller, the second clamping plate 321 will move closer to the first clamping plate 311 again under the elastic force of the supporting spring 323, and clamp the cloth roller shaft together with it, and at the same time, through the cooperation with the second rolling limiting element 324, the upper and lower surfaces of the cloth roller shaft are limitedly clamped, thereby ensuring the stable installation and precise positioning of the cloth roller.

[0056] See also Figure 7 and Figure 8 As shown: the axial limit module 4 includes a second mounting frame 41, a limit plate 42, a third guide rod 43, a drive screw 44 and a drive knob 45; the second mounting frame 41 is fixedly arranged on the top of the base frame 1 and is arranged on a side close to the guide module 2; the limit plate 42 is vertically arranged on a side of the second mounting frame 41 close to the cloth winding roller; the third guide rod 43 is vertically arranged on a side of the limit plate 42 close to the second mounting frame 41, and the rod portion of the third guide rod 43 is arranged through the second mounting frame 41 and is slidably matched with the second mounting frame 41; the drive screw 44 is vertically arranged through the second mounting frame 41 and is rotatably connected to the limit plate 42, and the drive screw 44 is screwed to the second mounting frame 41; the drive knob 45 is coaxially fixedly arranged on the end of the drive screw 44 away from the limit plate 42.

[0057] When the axial limit position of the cloth roller needs to be adjusted, the staff only needs to turn the driving knob 45 according to actual needs, and the driving knob 45 drives the driving screw 44 fixedly connected thereto to rotate synchronously. During the rotation of the driving screw 44, combined with the guiding effect of the third guide rod 43, the limit plate 42 is driven to be arranged close to the cloth roller in the horizontal direction, so that the limit plate 42 is used to apply an axial thrust to the cloth roller. Through the continuous pushing of the limit plate 42, the cloth roller is gradually adjusted to the predetermined axial position. When the axial position of the cloth roller is adjusted to the correct position, the staff stops turning the driving knob 45 to complete the axial correction operation of the cloth roller.

[0058] See also Fig.10As shown: the tensioning module 6 includes a sliding frame 62, a linear drive 63, a fixed roller 64, a movable roller 65, a first slider 66 and a locking bolt 67; there are two sliding frames 62, and the two sliding frames 62 are symmetrically slidably arranged on the first mounting frame 61 in a vertical state; the fixed roller 64 is rotatably arranged across the two sliding frames 62 and is arranged near the top of the sliding frame 62; the movable roller 65 is rotatably arranged across the two sliding frames 62 through the first slider 66, and the movable roller 65 can slide back and forth along the long side direction of the sliding frame 62 through the first slider 66; there are two linear drives 63, and the two linear drives 63 are fixedly arranged at the bottom of both sides of the first mounting frame 61 in a vertical state, and the output shafts of the two linear drives 63 are fixedly connected to the sliding frame 62; the locking bolt 67 is connected to one side of the sliding frame 62, and the locking bolt 67 passes through the sliding frame 62 and abuts against the first slider 66.

[0059] In order to ensure that the cloth wound by the cloth winding roller is always kept in a taut state, first, the staff loosens the locking bolt 67 to unlock the movable roller 65. Then, according to the current thickness of the cloth, the distance between the fixed roller 64 and the movable roller 65 is adjusted so that the gap between the two slightly clamps the cloth. This adjustment ensures that the cloth can stably slide between the fixed roller 64 and the movable roller 65 when being pulled by external force, thereby effectively preventing the cloth from losing tension due to looseness in the non-transmission state, and always keeping it in a taut state for winding.

[0060] On this basis, if the cloth winding force needs to be further adjusted, an external power source can be connected to drive the electric push rod of the linear driver 63 to extend its output shaft, and synchronously drive the sliding frame 62 to slide along the long side direction of the sliding frame 62 to achieve the effect of rising or falling. This process can change the conduction stroke of the cloth, thereby further adjusting the tension of the cloth. The specific driving stroke is adjusted according to the required tension to ensure that the cloth winding state is always in the optimal tension state.

[0061] The cloth inspection machine comprises a cloth rolling roller detachable unwinding bracket mechanism.

[0062] The present invention can not only realize efficient disassembly, assembly and positioning of cloth rolling rollers of different models, but also can self-regulate the tension of the cloth.

It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
