Description

Technical Field

[0001] This invention relates to the field of fabric inspection machine technology, specifically to a fabric inspection machine and method for inspecting embroidered fabric. Background Technology

[0002] In the embroidered fabric production and processing stage of the textile industry, automatic fabric inspection machines are core equipment for ensuring the quality of embroidered fabrics. Their typical structure usually includes four core modules: a head unwinding mechanism, an inspection body, a tail winding mechanism, and a control system. The unwinding mechanism typically consists of a fixed support and a rotatable drum. The embroidered fabric to be inspected is wound around the outside of the drum, and the drum is rotated by a motor to release the fabric. The inspection body, as a core functional module, usually integrates an image acquisition unit, a light source assembly, and a data processing unit. The image acquisition unit takes real-time pictures of the embroidered fabric during transport, and the data processing unit analyzes the fabric surface using image algorithms to check for defects such as broken threads, missed embroidery, stains, and pinholes, and controls a marking component to mark the defect locations. The winding mechanism is similar in structure to the unwinding mechanism, using a motor to drive the winding drum to rewind and store the inspected embroidered fabric. The control system uses a PLC or industrial computer to achieve coordinated control of all mechanisms. Operators can set inspection parameters, view inspection data, and defect statistics reports via a touchscreen.

[0003] Existing fabric inspection machines used for testing embroidered fabrics have limited roll capacity during continuous production. After a roll of embroidered fabric is inspected, a new spare roll needs to be replaced and the old and new fabrics need to be spliced ​​together. The splicing operation has a low degree of automation. Most machines require manual shutdown to manually align the end of the old fabric with the beginning of the new fabric, and then splice them together by means of adhesive tape bonding, needle and thread sewing or hot pressing welding. However, manual operation is very time-consuming, with long downtime and low testing efficiency.

[0004] Therefore, there is an urgent need to design a fabric inspection machine for testing embroidered fabrics to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a fabric inspection machine and method for inspecting embroidered fabric, in order to solve the problems mentioned in the background art. In the continuous production process, existing fabric inspection machines for inspecting embroidered fabric have limited roll capacity of the unwinding mechanism. After one roll of embroidered fabric is inspected, a new spare roll needs to be replaced and the old and new fabrics need to be spliced ​​together. The splicing operation has a low degree of automation. Most machines require manual shutdown to manually align the end of the old fabric with the beginning of the new fabric, and then splice them together by means of adhesive tape bonding, needle and thread sewing or hot pressing welding.

The two ends of the V-shaped spring are respectively inserted into the two snap-fit ​​grooves.

[0021] Preferably, double-sided adhesive is attached to the side of the spare embroidery fabric away from the positioning roller.

[0022] Preferably, the rolling mechanism includes two bearing inclined bars and two limiting inclined bars, which are respectively fixedly connected to the right side of the two wall panels. The bearing inclined bars are located below the limiting inclined bars. The free ends of the bearing inclined bars and the limiting inclined bars are inclined to the upper right.

A counterweight clamp is fixedly sleeved on the outside of the insertion protrusion. The counterweight clamp is located to the upper right of the upper guide roller.

[0023] Preferably, a method for using a fabric inspection machine to test embroidered fabric includes the following steps: Step 1: First, input the length, diameter, and embroidery fabric thickness of the first roll into the control panel. Then, the control panel controls the clamping motor to run. Next, the clamping motor drives the bidirectional screw to rotate. Then, the bidirectional screw drives the two displacement sliders to move closer to each other. Then, the two displacement sliders drive the two clamping plates to move closer to each other through the corresponding thin neck strips. Then, the distance between the end of the first roll and the clamping plate gradually decreases, restricting the first roll to the middle position. At this time, the first roll can rotate freely, and the distance between the clamping plate and the end face of the first roll is less than five millimeters. Step 2: Use the control panel to start the detection machine, the tail winding mechanism and the release motor in sequence. Then the release motor drives the release roller to rotate counterclockwise. Next, the release roller drives the first roll and the embroidery fabric to be tested on it to rotate clockwise. Then the embroidery fabric to be tested is released from the outside of the first roll. At the same time, the detection machine and the tail winding mechanism provide traction force to the embroidery fabric to be tested, so that the embroidery fabric to be tested is taut. Then the detection machine detects and marks the embroidery fabric to be tested. Then the tail winding mechanism winds up the detected embroidery fabric. Step 3: Apply a pushing force to the electric roller to bring it closer to the base vertical bar. Then, take the spare material roll with the spare embroidery fabric wound on it. Next, place the end of the spare material roll on the transition plate. Then, slide the spare material roll along the surface of the transition plate into the slide between the two guide strips and fall into the arc groove. Then, release the electric roller. Then, under the action of the V-shaped spring force, the rotating arm rotates the electric roller towards the direction of the spare material roll through the mounting shaft. Then, the electric roller presses on the surface of the spare embroidery fabric wound on the outside of the spare material roll. Then, pull the end of the spare embroidery fabric downward and let it pass around the left side of the positioning roller, ensuring that a section of the end of the spare embroidery fabric hangs vertically below the positioning roller. Then, stick double-sided tape on the bottom end of the spare embroidery fabric away from the side of the positioning roller. Step 4: The vertical probe monitors the vertical distance between the preparation roll and the first roll in real time, while the tilt probe monitors the tilt distance between the preparation roll and the fabric to be tested on the surface of the first roll. Both probes send their data to the control panel. The control panel estimates the number of layers of embroidered fabric to be tested outside the first roll based on the data and the tilt angle of the tilt probe. When the number of layers decreases to ten, the control panel controls the electric roller to operate. The electric roller then drives the spare embroidered fabric to be released from outside the preparation roll. The bottom of the spare embroidered fabric then approaches the surface of the release roller, and finally contacts the surface of the release roller. The counter-clockwise rotating release roller, under the friction between itself and the spare embroidered fabric, then... A leftward thrust is applied, causing the bottom end of the spare embroidery fabric to tilt to the left. The bottom end of the spare embroidery fabric then contacts the embroidery fabric to be tested on the surface of the clockwise rotating first roll. The edge of the double-sided adhesive initially bonds the surface of the embroidery fabric to be tested to the end of the spare embroidery fabric. Then, the release roller surface and the surface of the first roll simultaneously pull the end of the spare embroidery fabric into the gap between them. The end of the spare embroidery fabric is then clamped between the release roller surface and the surface of the first roll. The first roll and its surface completely roll over the area covered by the double-sided adhesive, bonding the embroidery fabric to be tested and the spare embroidery fabric together. Finally, the embroidery fabric on the outside of the first roll completely rolls over the area covered by the double-sided adhesive. Full release: The embroidery fabric to be tested is released from the outside of the preparation roll using double-sided adhesive. The embroidery fabric joint passes through the gap between the counterweight clamp and the upper guide roller. Under the action of gravity, the counterweight clamp, carrying the insertion protrusion, slides downward and to the left along the track slit until the counterweight clamp presses the embroidery fabric to be tested onto the surface of the upper guide roller, performing a secondary crushing effect for a stronger bond. Then, the upstream probe detects the distance change and transmits the data to the control panel. The control panel determines the presence of the joint based on the distance change, and then controls the electric telescopic rod to shorten. Next, the transfer slider moves the auxiliary roller away from the release roller, increasing the gap between the release roller and the auxiliary roller. Then, the first roll falls downward through the gap under the action of gravity and lands on the top surface of the transfer ramp. The first roll rolls down the inclined plane of the transfer plate, automatically detaching it. Then, the control panel extends the electric telescopic rod to reset the auxiliary roller. Next, the control panel controls the material preparation motor, which drives the material preparation screw. The release slider, through its threaded engagement with the material preparation screw and the insertion action between the release track and the release groove, moves the material preparation tray and strip downwards. The material preparation strip then supports the material roll downwards through the arc groove. The spare embroidered fabric on the surface of the material roll applies a pushing force to the positioning roller. The positioning roller, carrying the positioning block, moves towards the cylindrical channel, rolling on the surface of the spare embroidered fabric. Finally, the material roll and the spare embroidered fabric on it pass over the positioning roller.Under the force of the traction spring, the positioning block moves the positioning roller to the left to reset. Then, the material roll and the spare embroidery fabric on it fall onto the surface of the release roller and auxiliary roller. Next, the arc groove separates from the material roll. Then, when the material tray moves downward to its extreme position, the control panel stops the material motor and extends the electric push rod. The electric push rod then applies a pushing force to the material tray, causing the material tray, along with the material support strip, to move towards the direction of the rectangular through hole. The control panel then reverses the direction of the material motor, and the material tray moves upward to its extreme position. The control panel then stops the material motor and shortens the electric push rod. Under the elastic force of the traction spring, the material tray, along with the material support strip, moves towards the direction of insertion into the rectangular through hole. Then, the material support strip and the arc groove reset. The third step is then repeated to install the spare embroidery fabric.

[0024] Compared with the prior art, the beneficial effects of the present invention are: This invention, through its clamping mechanism, can adapt to first rolls and preparation rolls of different lengths, thus improving applicability. It avoids fabric offset caused by axial movement of the first roll and preparation roll. The roll transferor can automatically disassemble the empty first roll without manual operation, saving time and effort. The disengagement mechanism can automatically trigger the splicing process without constant human monitoring, reducing misjudgment of splicing timing, ensuring the continuity of the testing machine's testing of the embroidered fabric, reducing the probability of testing interruptions caused by human intervention, saving workers more time and effort, and helping to increase production efficiency.

[0025] This invention uses a material preparation mechanism to move the spare embroidery fabric downwards, reducing the distance between the spare embroidery fabric and the unwinding mechanism. This reduces the impact force generated when the material preparation roll carrying the spare embroidery fabric enters the test position, mitigating the impact on the movement of the embroidery fabric and making its movement more stable. Consequently, the force on the embroidery fabric joint is kept within a safe range, ensuring that the joint will not be pulled apart. The material preparation roll can be released through a release mechanism, while the material preparation mechanism can be reset upwards without affecting the material preparation roll, preparing for the installation of the spare embroidery fabric. A positioning mechanism restricts the end of the spare embroidery fabric, ensuring that the free end of the spare embroidery fabric points downwards between the vertical plane passing through the central axis of the first roll and the vertical plane passing through the central axis of the release roller. This ensures that the end of the spare embroidery fabric can enter the gap between the first roll and the release roller, providing the necessary conditions for automatic splicing.

[0026] This invention utilizes a splicing mechanism to drive the spare embroidery fabric to be released from the outside of the preparation roll, allowing the end of the spare embroidery fabric to enter the gap between the first roll and the release roller. Simultaneously, the splicing mechanism can bond the spare embroidery fabric to the embroidery fabric to be tested, achieving an initial connection. The first roll and the release roller squeeze the joint between the two embroidery fabrics, improving the bonding effect. The rolling mechanism can perform a secondary squeeze at the joint between the two embroidery fabrics, further enhancing the bonding effect. This achieves automatic splicing without stopping the machine, saving time and labor, and increasing testing efficiency. Attached Figure Description

[0029] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0031] like Figures 1-20As shown, this application provides a fabric inspection machine for inspecting embroidered fabric, comprising: a base plate 1, a machine head unwinding 2 fixedly installed on the left end of the top surface of the base plate 1, an inspection body 3 fixedly installed in the middle of the top surface of the base plate 1, and a machine tail winding mechanism 4 fixedly installed on the right end of the top surface of the base plate 1. A control panel 5 is fixedly installed on the front of the inspection body 3. A first roll 206 is placed on the machine head unwinding 2, and the position of the first roll 206 is the position to be inspected. One end of the embroidered fabric to be inspected is wound around the outside of the first roll 206, and the other end of the embroidered fabric to be inspected passes through the inspection body 3 and is wound onto the machine tail winding mechanism 4. The inspection body 3 is used to inspect the fabric. The embroidery fabric is automatically detected and marked. A clamping mechanism 6 is located at the bottom of the unwinding head 2, which restricts the first roll 206 to the middle position of the unwinding head 2. A roll transferor 7 is located at the left end of the unwinding head 2, which automatically discharges the first roll 206. A material preparation mechanism 8 is located on the clamping mechanism 6, on which a material preparation roll 809 is placed. The material preparation roll 809 is in a spare position, and spare embroidery fabric is wound around its exterior. The material preparation mechanism 8 can move downwards with the spare embroidery fabric via the material preparation roll 809 to reduce the distance between the spare embroidery fabric and the machine. The distance between the unwinding head 2 reduces the impact force generated when the preparation roll 809 carries the spare embroidery fabric into the test position, mitigating the impact on the movement of the embroidery fabric and making its movement more stable. This ensures that the force on the embroidery fabric joint is within a safe range, preventing the joint from being pulled apart. The preparation mechanism 8 is equipped with a release mechanism 9, which can drive the preparation mechanism 8 to release the preparation roll 809, ensuring that the preparation roll 809 carries the spare embroidery fabric into the test position. The top of the unwinding head 2 is equipped with a positioning mechanism 10, which can position the free end of the spare embroidery fabric. The positioning mechanism 10 is positioned so that the free end of the spare embroidery fabric points to a position near the right side of the first roll 206. The top of the positioning mechanism 10 is provided with a splicing mechanism 11, which drives the spare embroidery fabric to be released from the outside of the preparation roll 809, so that the free end of the spare embroidery fabric gradually decreases. This is used to make the free end of the spare embroidery fabric adhere to the area of ​​the tail end of the embroidery fabric to be tested outside the first roll 206 and achieve connection. The right side of the unwinding mechanism 2 is provided with a crushing mechanism 12. The unwinding mechanism 2 and the crushing mechanism 12 can squeeze the connection area between the spare embroidery fabric and the embroidery fabric to be tested, so that the connection between the spare embroidery fabric and the embroidery fabric to be tested is more reliable.

[0032] Please refer to the figure. Figure 3 and Figure 4The unwinding head 2 includes two wall panels 201, which are symmetrically distributed along the direction perpendicular to the paper surface. Both wall panels 201 are fixedly connected to the top surface of the base plate 1. A lower guide roller 202 is rotatably mounted between the two wall panels 201 at its bottom. An upper guide roller 203 is rotatably mounted between the two wall panels 201 above the lower guide roller 202. A release roller 204 is rotatably mounted between the two wall panels 201 at its upper left and to the left of the upper guide roller 203. An auxiliary roller 205 is rotatably mounted between the two wall panels 201 at its left. A first roll 206 is placed above the gap between the release roller 204 and the auxiliary roller 205, and the gap does not allow the first roll 206 to pass through. The first roll 206 is in contact with the release roller 204 and the auxiliary roller 205 through the embroidery fabric to be tested on its surface. The embroidery fabric to be tested is wound clockwise outside the first roll 206. The free end of the embroidery fabric to be tested passes through the gap in sequence, goes around the left side of the release roller 204, goes around the right side of the upper guide roller 203, and goes around the left side of the lower guide roller 202 before extending into the detection body 3. The release motor 207 is bolted on the front of the wall panel 201 closest to the front of the support leg 101. The output shaft of the release motor 207 is fixedly connected to the end of the release roller 204. The release motor 207 is controlled by the control panel 5. The release motor 207 drives the release roller 204 to rotate counterclockwise to drive the embroidery fabric to be tested to be released from outside the first roll 206.

[0033] Please see Figure 3 , Figure 4 and Figure 5 The clamping mechanism 6 includes a support slide rod 601, which is fixedly connected between two wall panels 201 and located at their lower left corner. Two displacement sliders 602 are symmetrically slidably sleeved on the outside of the support slide rod 601. The two displacement sliders 602 are connected in series by a bidirectional screw 603. The bidirectional screw 603 and the two displacement sliders 602 are threadedly engaged. The two ends of the bidirectional screw 603 are rotatably connected to the surfaces of the two wall panels 201. A clamping motor 604 is fixedly connected to the front of the bidirectional screw 603. The clamping motor 604 is bolted to the front of the corresponding wall panel 201. A thin neck strip 605 is fixedly connected to the top surface of the displacement slider 602. The top end of the thin neck strip 605 passes through the gap and is fixedly connected to a clamping plate 606. The two clamping plates 606 restrict the first drum 206 to the middle position.

[0034] The spacing of the clamping plate 606 is adaptively adjusted by the threaded engagement of the bidirectional screw 603 and the displacement slider 602, ensuring stable positioning of the first drum 206 of different lengths and preventing axial movement.

[0035] Please see Figure 3 , Figure 6 and Figure 7The roll transferor 7 includes two openings 701, which are respectively located at the top of the left side of the two wall panels 201. Guide grooves 702 are provided on both the upper and lower surfaces of the inner cavity of each opening 701. A transfer slider 703 is slidably inserted into the opening 701. Guide strips 704 are fixedly connected to both the upper and lower surfaces of the transfer slider 703, and the guide strips 704 are slidably inserted into the guide grooves 702. A bearing hole 705 extending perpendicular to the paper surface is provided on the transfer slider 703. The two ends of the auxiliary roller 205 are rotatably inserted into the bearing holes 705 on the two transfer sliders 703. The left side of the two wall panels 201 has a countersunk hole 706 that communicates with the opening hole 701. A cover plate 707 is inserted into the countersunk hole 706. The cover plate 707 is bolted to the inner wall of the countersunk hole 706. An electric telescopic rod 708 is bolted to the middle of the left side of the cover plate 707. The electric telescopic rod 708 is controlled by the control panel 5. The extension rod of the electric telescopic rod 708 passes through the cover plate 707 and is fixedly connected to the left side of the transfer slider 703. The electric telescopic rod 708 can move the auxiliary roller 205 to the left through the transfer slider 703 to increase the gap so that the first drum 206 can pass through the gap.

[0036] The auxiliary roller 205 is moved laterally by the electric telescopic rod 708 to increase the unwinding gap, providing the necessary space for the automatic discharge of the subsequent empty first roll 206.

[0037] Please refer to the figure. Figure 5 On the two surfaces of the two thin neck strips 605 that are close to each other, there are fixed transfer inclined plates 709. The transfer inclined plates 709 guide the first roll 206 so that the first roll 206 is discharged to the left.

[0038] The inclined structure guides the empty first roll 206 out, avoiding jamming or deviation during the discharge process and improving the reliability of automated roll stacking.

[0039] Please see Figure 8 , Figure 9 , Figure 10 and Figure 11The material preparation mechanism 8 includes two material preparation plates 801, which are fixedly connected to two mutually spaced surfaces of two clamping plates 606. A rectangular hole 802 is provided on each material preparation plate 801, and a rectangular through hole 803 is provided on each clamping plate 606, communicating with the rectangular hole 802. A material preparation motor 804 is bolted to the top surface of each material preparation plate 801. The material preparation motor 804 is controlled by the control panel 5. The bottom end of the output shaft of the material preparation motor 804 extends downward into the rectangular hole 802 and is fixedly connected to a material preparation screw 805. The bottom end of the material preparation screw 805 is rotatably inserted into the bottom surface of the inner cavity of the rectangular hole 802. A material preparation support plate 806 is threaded onto the outside of the material preparation screw 805 and slidably inserted into the rectangular hole 802. The material preparation support plate 806 is close to the rectangular hole 802. A material support strip 807 located in the middle is fixedly connected to the side of the rectangular through hole 803. The release mechanism 9 is provided on the material support plate 806 and the material support strip 807. The free end of the material support strip 807 passes through the rectangular through hole 803 and extends into the space between the two clamping plates 606. An arc groove 808 is provided on the top surface of the material support strip 807 at its end. The arc groove 808 is fastened to the surface of the end of the material roll 809 from below. The spare embroidery cloth is wound clockwise around the outside of the material roll 809. The material motor 804 is threaded with the material support plate 806 through the material screw 805. The material support strip 807 and the arc groove 808 support the material roll 809 to move downward, so as to reduce the drop and reduce the impact. The specifications of the material roll 809 are the same as those of the first roll 206.

[0040] The material preparation drum 809 is driven vertically downward by the material preparation motor 804, which reduces the initial drop between the spare fabric and the unwinding 2 of the machine head, effectively reducing the impact force when the material preparation drum 809 is in place and protecting the fabric joint.

[0041] Please see Figure 4 , Figure 9 , Figure 10 , Figure 11 and Figure 12The release mechanism 9 includes a release hole 901, which is formed on the material preparation plate 806 and the material preparation strip 807. Release grooves 902 are formed on both sides of the inner cavity of the release hole 901. A release slider 903 is slidably inserted into the release hole 901. A threaded hole is formed on the release slider 903, and a material preparation screw 805 is movably inserted into the threaded hole with a threaded fit. Release tracks 904 are fixedly connected to both sides of the release slider 903, and the release tracks 904 are slidably inserted into the release grooves 902. An assembly countersunk hole 905 communicating with the release hole 901 is formed on the side of the material preparation plate 806 away from the clamping plate 606. A sealing plate 906 is bolted into the assembly countersunk hole 905. The release slider 903 and the sealing plate 906... At contact point 06, two mounting square grooves 907 are symmetrically opened on the end face of the material preparation tray 806 near the clamping plate 606, and two wire holes 908 are symmetrically opened on the end face of the material preparation tray 806 away from the clamping plate 606. The two wire holes 908 are respectively connected to the two mounting square grooves 907. An electric push rod 909 is fixedly installed inside the mounting square groove 907. The electric push rod 909 is controlled by the control panel 5. A ball bearing 910 is movably embedded on the end face of the protruding rod inside the electric push rod 909. The ball bearing 910 rolls on the surface of the clamping plate 606. When the electric push rod 909 extends, it can apply a counter-pushing force to the material preparation tray 806, so that the material preparation tray 806 can carry the material preparation strip 807 into the rectangular hole 802 for releasing the material preparation drum 809.

[0042] The material preparation strip 807 is retracted into the rectangular hole 802 by the electric push rod 909, thereby separating the material preparation drum 809 from the material preparation mechanism 8 and ensuring that the material preparation drum 809 enters the inspection position stably. A middle vertical plate 911 is fixedly connected to the middle of the top surface of the release slider 903. Edge vertical plates 913 are fixedly connected to the two corners of the top surface of the material preparation plate 806 away from the clamping plate 606. Hanging holes are provided on the middle vertical plate 911 and the two edge vertical plates 913. A traction spring 912 is connected between the middle vertical plate 911 and the two edge vertical plates 913 through the hanging holes. The traction spring 912 applies a restoring force to the material preparation plate 806, so that the material preparation plate 806, along with the material preparation strip 807, extends between the two clamping plates 606 for placing the subsequent material preparation roll 809.

[0043] The traction spring 912 provides continuous power for the reset of the material preparation mechanism 8, ensuring that after the material preparation drum 809 is released, the material preparation support bar 807 can quickly return to the initial position, which facilitates the subsequent installation of the material preparation drum 809.

[0044] A vertical probe 914 and an inclined probe 915 are fixedly installed in the middle of the bottom surface of the mounting groove 907. The vertical probe 914 points vertically to the surface of the first roll 206, and the inclined probe 915 points obliquely to the embroidery fabric to be tested on the surface of the first roll 206. The control panel 5 can infer the number of layers of the embroidery fabric to be tested on the first roll 206 based on the data detected by the vertical probe 914 and the inclined probe 915.

[0045] By combining vertical and tilt detection data, the number of fabric layers on the first roll 206 can be accurately calculated, providing a precise basis for timing judgment for automatic splicing and triggering.

[0046] Two guide strips 916 are fixedly connected to the two sides of the two clamping plates 606 that are close to each other. The two guide strips 916 are symmetrically distributed on both sides of the rectangular through hole 803. The material preparation drum 809 is slidably inserted into the slide rail formed between the two guide strips 916 and can slide vertically downward. A transition bending plate 917 is fixedly connected to the top of the guide strip 916. The top of the transition bending plate 917 bends outward to increase the opening and facilitate the placement of the material preparation drum 809.

[0047] By combining the guide rail 916 slide and the transition bend 917 to enlarge the opening, the difficulty of placing the spare drum and material preparation drum 809 is reduced. Even with manual assistance, it can be quickly positioned, improving the ease of operation.

[0048] Please see Figure 3 , Figure 13 , Figure 14 and Figure 15 The positioning mechanism 10 includes two support legs 101, which are fixedly connected to the top surfaces of the two wall panels 201 respectively. A positioning strip 102 is fixedly connected to the top of the support leg 101. A positioning roller 103 is rotatably installed between the two positioning strips 102. The free end of the spare embroidery cloth passes around the left side of the positioning roller 103. The positioning roller 103 restricts the end of the spare embroidery cloth so that the free end of the spare embroidery cloth points downward between the vertical plane passing through the central axis of the first roll 206 and the vertical plane passing through the central axis of the release roller 204.

[0049] The positioning roller 103 restricts the end of the spare embroidery fabric to a specific area, ensuring that the docking position of the spare fabric and the old fabric is accurate, laying the positional foundation for subsequent automatic splicing.

[0050] A square channel 104 is formed on the end face of the positioning strip 102 away from the support leg 101. Both the upper and lower surfaces of the square channel 104 have arc-shaped slide rails 105. Positioning sliding holes 106 communicating with the square channel 104 are formed on the two sides of the two positioning strips 102 that are close to each other. A positioning block 107 is slidably inserted into the square channel 104. A ball 108 is movably embedded on both the upper and lower surfaces of the positioning block 107. The ball 108 rolls within the arc-shaped slide rails 105. Positioning through holes 109 are provided on the 07. The two ends of the positioning roller 103 are rotatably inserted into the positioning through holes 109 on the two positioning blocks 107. A traction spring 110 is fixedly connected to the end face of the positioning block 107 near the support leg 101. A cylindrical channel 111 is provided inside the support leg 101. The traction spring 110 is movably inserted into the cylindrical channel 111 and fixedly connected to a rotating cap 112. The rotating cap 112 is threadedly installed inside the cylindrical channel 111.

[0051] Please see Figure 8 and Figure 9 Both clamping plates 606 have small openings 113 on their sides near the detection body 3, and the positioning roller 103 is movably inserted into the small openings 113.

[0052] Please see Figure 3 , Figure 4 , Figure 16 , Figure 17 and Figure 18 , Figure 20The splicing mechanism 11 includes two basic vertical bars 1101, which are fixedly connected to the ends of the top surfaces of two positioning bars 102. A fixing block 1102 is fixedly connected to the side of each basic vertical bar 1101 near the support leg 101, located at its bottom. A flipping shaft 1103 is fixedly connected to the end face of the fixing block 1102. A flipping arm 1104 is rotatably sleeved on the outside of the flipping shaft 1103. An installation through hole 1105 is opened inside the flipping arm 1104 at its other end. An installation shaft 1106 is fixedly inserted into the installation through hole 1105. An electric roller 1107 is rotatably mounted on the outside of the installation shaft 1106. The exterior is provided with anti-slip texture. The electric roller 1107 is controlled by the control panel 5. The electric roller 1107 presses on the surface of the spare embroidery fabric outside the preparation roll 809. The two sides of the base vertical bar 1101 and the flip arm 1104 that are close to each other are provided with locking grooves 1108. A V-shaped spring 1109 is installed between the two locking grooves 1108. The two ends of the V-shaped spring 1109 are respectively inserted into the two locking grooves 1108 to apply pressure to the electric roller 1107, increase the pressure between the electric roller 1107 and the spare embroidery fabric, and ensure that the electric roller 1107 can drive the spare embroidery fabric to be released from the outside of the preparation roll 809, so that the end of the spare embroidery fabric falls on the surface of the release roller 204.

[0053] The pressure provided by the V-shaped spring 1109 ensures stable friction between the electric roller 1107 and the spare fabric, enabling the spare fabric to be released at a uniform speed and avoiding wrinkles caused by excessively rapid release.

[0054] Double-sided adhesive 1110 is attached to the side of the spare embroidery fabric away from the positioning roller 103. As the release roller 204 and the first roll 206 rotate, the end of the spare embroidery fabric is clamped in the gap between the release roller 204 and the first roll 206. The double-sided adhesive 1110 is attached to the surface of the embroidery fabric to be tested. The release roller 204 and the first roll 206 squeeze the area where the double-sided adhesive 1110 is located to achieve preliminary bonding and achieve the purpose of splicing.

[0055] Please see Figure 3 and Figure 19The rolling mechanism 12 includes two bearing inclined bars 121 and two limiting inclined bars 122. The two bearing inclined bars 121 and the two limiting inclined bars 122 are respectively fixedly connected to the right side of the two wall panels 201. The bearing inclined bars 121 are located below the limiting inclined bars 122. The free ends of the bearing inclined bars 121 and the limiting inclined bars 122 are inclined to the upper right. A track slit 123 is formed between the bearing inclined bars 121 and the limiting inclined bars 122. An insertion protrusion 124 is slidably inserted into the track slit 123. A counterweight clamp 125 is fixedly sleeved on the outside of the insertion protrusion 124. The counterweight clamp 125 is located to the upper right of the upper guide roller 203. The counterweight clamp 125 presses the embroidery cloth to be tested onto the surface of the upper guide roller 203. The counterweight clamp 125 performs secondary rolling on the area where the double-sided adhesive 1110 is located, resulting in better and stronger adhesion.

[0056] Under the influence of gravity, the counterweight clamping roller 125 slides along the track slit 123 to the lower left, carrying the insertion protrusion 124, until the counterweight clamping roller 125 presses the embroidery cloth to be tested onto the surface of the upper guide roller 203, thus playing a secondary crushing role.

[0057] Please see Figure 1 and Figure 2 An upstream probe 301 and a downstream probe 302 are fixedly installed on the left and right sides of the detection body 3, respectively. The upstream probe 301 and the downstream probe 302 are used to detect the joint between the spare embroidery cloth and the embroidery cloth to be tested. The upstream probe 301 and the downstream probe 302 are connected to the control panel 5 for information transmission.

[0058] A method for using a fabric inspection machine to test embroidered fabric includes the following steps: Step 1: First, input the length, diameter, and embroidery fabric thickness data of the first roll 206 into the control panel 5. Then, the control panel 5 controls the clamping motor 604 to run. Next, the clamping motor 604 drives the bidirectional screw 603 to rotate. Then, the bidirectional screw 603 drives the two displacement sliders 602 to move closer to each other. Then, the two displacement sliders 602 respectively drive the two clamping plates 606 to move closer to each other through the corresponding thin neck strips 605. Then, the distance between the end of the first roll 206 and the clamping plate 606 gradually decreases, restricting the first roll 206 to the middle position. At this time, the first roll 206 can rotate freely, and the distance between the clamping plate 606 and the end face of the first roll 206 is less than five millimeters. Step 2: Using the control panel 5, start the detection body 3, the tail winding mechanism 4 and the release motor 207 in sequence. Then, the release motor 207 drives the release roller 204 to rotate counterclockwise. Next, the release roller 204 drives the first roll 206 and the embroidery fabric to be tested on it to rotate clockwise. Then, the embroidery fabric to be tested is released from the outside of the first roll 206. At the same time, the detection body 3 and the tail winding mechanism 4 provide traction force to the embroidery fabric to be tested, so that the embroidery fabric to be tested is taut. Then, the detection body 3 detects and marks the embroidery fabric to be tested. Then, the tail winding mechanism 4 winds up the detected embroidery fabric. Step 3: Apply a pushing force to the electric roller 1107, causing it to move closer to the base vertical bar 1101. Then, take the material roll 809 wrapped with spare embroidery fabric, place the end of the material roll 809 on the transition bending plate 917, and then slide the material roll 809 along the surface of the transition bending plate 917 into the slide between the two guide bars 916 and fall into the arc groove 808. Then, release the electric roller 1107, and then flip the large arm 1104 to the V-shaped spring 110. 9. Under the action of elasticity, the electric roller 1107 is rotated in the direction of the material preparation roll 809 by the mounting shaft 1106. Then, the electric roller 1107 presses on the surface of the spare embroidery cloth wrapped around the outside of the material preparation roll 809. Then, the end of the spare embroidery cloth is pulled down and wrapped around the left side of the positioning roller 103, ensuring that a section of the end of the spare embroidery cloth hangs vertically below the positioning roller 103. Then, double-sided tape 1110 is pasted on the bottom end of the spare embroidery cloth away from the side of the positioning roller 103. Step 4: Vertical probe 914 monitors the vertical distance between the preparation roll 809 and the first roll 206 in real time, while tilt probe 915 monitors the tilt distance between it and the fabric to be tested on the surface of the first roll 206 in real time. Vertical probe 914 and tilt probe 915 send the detected data to control panel 5. Control panel 5 estimates the number of layers of the embroidery fabric to be tested outside the first roll 206 based on the detected data and the tilt angle of tilt probe 915. When the number of layers of the embroidery fabric to be tested outside the first roll 206 decreases to ten layers, control panel 5 controls electric roller 1107 to run. Then, electric roller 1107 drives the spare embroidery fabric to be released from outside the preparation roll 809. Next, the bottom end of the spare embroidery fabric approaches the surface of release roller 204. Afterwards, the spare embroidery fabric... The bottom end of the embroidered fabric contacts the surface of the release roller 204. Then, the counterclockwise rotating release roller 204, under the action of friction between itself and the spare embroidered fabric, applies a leftward pushing force to the bottom end of the spare embroidered fabric. Next, the bottom end of the spare embroidered fabric tilts to the left, and then the bottom end of the spare embroidered fabric contacts the embroidered fabric to be tested on the surface of the clockwise rotating first roll 206. Then, the edge of the double-sided adhesive 1110 initially bonds the surface of the embroidered fabric to be tested to the end of the spare embroidered fabric. Then, the surface of the release roller 204 and the surface of the first roll 206 simultaneously pull the end of the spare embroidered fabric into the gap between the surface of the release roller 204 and the surface of the first roll 206. After that, the end of the spare embroidered fabric is clamped between the surface of the release roller 204 and the surface of the first roll 206. Between the embroidery fabrics to be tested, the first roll 206 and its surface completely roll over the area covered by double-sided adhesive 1110 on the embroidery fabric. The double-sided adhesive 1110 bonds the embroidery fabric to be tested and the spare embroidery fabric together. Then, the embroidery fabric to be tested outside the first roll 206 is completely released. The embroidery fabric to be tested is pulled by the double-sided adhesive 1110 and released from the outside of the preparation roll 809. The embroidery fabric joint passes through the gap between the counterweight clamp 125 and the upper guide roller 203. Under the action of gravity, the counterweight clamp 125, carrying the insertion protrusion 124, slides to the lower left along the track slit 123 until the counterweight clamp 125 presses the embroidery fabric to be tested onto the surface of the upper guide roller 203, which plays a secondary rolling role and makes the adhesion more firm. Afterwards, the upstream probe 301 detects the distance change and transmits the data to the control panel 5. The control panel 5 determines the presence of the joint based on the distance change, and then controls the electric telescopic rod 708 to shorten. Next, the transfer slider 703 moves the auxiliary roller 205 away from the release roller 204, and the gap between the release roller 204 and the auxiliary roller 205 increases. Then, the first drum 206 falls under the action of gravity and passes through the gap to land on the top surface of the transfer inclined plate 709. Then, the first drum 206 rolls down the inclined surface of the transfer inclined plate 709, realizing the purpose of automatically disassembling the first drum 206. Afterwards, the control panel 5 controls the electric telescopic rod 708 to extend, so that the auxiliary roller 205 returns to its original position. Then, the control panel 5 controls the material preparation motor 804 to run.Then, the material preparation motor 804 drives the material preparation screw 805 to rotate. Next, the disengagement slider 903, under the action of its threaded engagement with the material preparation screw 805, moves downwards through the insertion action between the disengagement track 904 and the disengagement groove 902, carrying the material preparation support plate 806 and the material preparation support strip 807. Then, the material preparation support strip 807 supports the material preparation drum 809 downwards through the arc groove 808. Then, the spare embroidery fabric on the surface of the material preparation drum 809 applies a pushing force to the positioning roller 103. Next, the positioning roller 103, carrying the positioning block 107, moves towards the direction of the cylindrical channel 111. The positioning roller 103 rolls on the surface of the spare embroidery fabric. Then, the material preparation drum 809 and the spare embroidery fabric on it pass over the positioning roller 103. Under the action of the traction spring 110, the positioning block 107 moves the positioning roller 103 to the left to reset. Then, the material preparation drum 809 and the spare embroidery fabric on it fall onto the release roller 204 and... On the surface of the auxiliary roller 205, the arc groove 808 separates from the material preparation drum 809. Then, when the material preparation plate 806 moves downwards to its extreme position, the control panel 5 stops the material preparation motor 804 and extends the electric push rod 909. The electric push rod 909 then applies a pushing force to the material preparation plate 806, causing the material preparation plate 806, along with the material preparation strip 807, to move towards the direction of pulling out the rectangular through hole 803. The control panel 5 then controls the material preparation motor 804 to run in the reverse direction, and the material preparation plate 806 moves upwards to its extreme position. The control panel 5 then stops the material preparation motor 804 and shortens the electric push rod 909. Under the elastic tension of the traction spring 912, the material preparation plate 806, along with the material preparation strip 807, moves towards the direction of inserting into the rectangular through hole 803. The material preparation strip 807 and the arc groove 808 then reset. The third step is then repeated to install the spare embroidery fabric.
