Description

Technical Field

[0001] This utility model relates to the technical field of fabric inspection machines, and in particular to a fabric spreading mechanism for a fabric inspection machine. Background Technology

[0002] Fabric inspection machines are key equipment in the textile industry used for quality inspection and evaluation of fabrics. They integrate mechanical transmission, optical detection, electrical control and data processing technology. They conduct comprehensive inspections of key indicators such as fabric surface defects, size specifications and color difference uniformity in an automated or semi-automated manner, thereby ensuring that the fabric quality meets production standards. A fabric spreading mechanism is required when the fabric is conveyed by the fabric inspection machine.

[0003] Chinese patent website discloses a fabric spreading mechanism for a fabric inspection machine, publication number CN221955410U. The mechanism includes a fabric inspection machine body with a spreading mechanism located at the inspection station. The spreading mechanism comprises a motor, a transmission belt, and fabric rolling rollers. At least two fabric rolling rollers are symmetrically arranged and rotatably mounted on the fabric inspection machine body, with the axis of the rollers forming an angle with the direction of fabric movement. The rotation direction of the rollers is consistent with the direction of fabric movement. The motor is installed within the fabric inspection machine body, and its power output is connected to one end of the fabric rolling rollers via the transmission belt. This spreading mechanism can laterally flatten the fabric being conveyed during operation without affecting its forward movement, aiming to prevent wrinkles or partial overlap of the fabric when passing through the inspection station, thus improving the inspection effect and accuracy.

[0004] The solution also has the following problems: the mechanism uses two rolling rollers to flatten the fabric, but the effect of unfolding the fabric by only using two rolling rollers is not good. The fabric may not be able to be unfolded due to sticking and wrinkles, resulting in poor flattening quality and low practicality. Therefore, it has certain drawbacks.

[0005] Therefore, in order to solve the above problems, this utility model provides a fabric spreading mechanism for a fabric inspection machine. Utility Model Content

[0006] The purpose of this invention is to provide a fabric spreading mechanism for a fabric inspection machine to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a fabric spreading mechanism for a fabric inspection machine, comprising a support frame, two sets of guide rollers installed at both ends of the top of the support frame, a support frame installed at one end of the top of the support frame, two fixed ears symmetrically installed at the bottom of the support frame, a rotating shaft installed on each fixed ear, a spreading roller installed at one end of the rotating shaft, a support frame installed at the top of the support frame away from the support frame, two rotating rods installed between the inner sidewalls of the support frame, a plurality of striking blocks installed on the outer ring surface of the rotating rods, limit plates installed at both ends of the bottom of the support frame and below the striking blocks, and a collection tray installed at the bottom of the support frame and between the two limit plates.

[0009] Preferably, one end of the other rotating shaft is equipped with a driven bevel gear, the driving bevel gear and the driven bevel gear mesh with each other, and the two spreading rollers are vertically distributed and their included angle is consistent with the fabric conveying direction.

[0010] Preferably, one end of the rotating rod extends through the outside of the support frame and is fitted with a pulley. The two pulleys are connected by a transmission belt. A fixing frame is installed on the outside of the support frame. A second drive motor is installed on the inner side wall of the fixing frame. The output shaft of the second drive motor is connected to one of the pulleys.

[0011] Preferably, the bottom outer side of the limiting plate is provided with a groove, and the two outer ends of the collecting plate and inside the groove are provided with limiting blocks, and the outside of the limiting blocks is provided with limiting tubes.

[0012] Preferably, a telescopic rod is installed on both sides of the groove outside the limiting plate, a return spring is installed on the outer ring surface of the telescopic rod, a handle is installed at one end of the telescopic rod, and a limiting rod is installed on the outside of the handle between the two telescopic rods.

[0015] In summary, this utility model has the following beneficial technical effects:

[0016] This fabric inspection machine uses a fabric spreading mechanism. After the second drive motor starts, its output shaft rotates, driving a connected pulley to rotate. This pulley, via a transmission belt, drives another pulley to rotate, which in turn drives two rotating rods to rotate. This causes the striking blocks to rotate and strike the fabric, further assisting in spreading the fabric. When the driving bevel gear rotates, it meshes with the driven bevel gear, driving the driven bevel gear to rotate. The driven bevel gear, in turn, drives another rotating shaft to rotate, causing both spreading rollers to rotate. The two spreading rollers are perpendicularly distributed and their included angle is perpendicular to the fabric. The conveying direction allows for better unfolding of the fabric. When the collection tray needs to be installed, pull the handle. The handle extends the telescopic rod, and the return spring is stretched. After the limiting block of the collection tray is placed into the groove, release the handle. Under the elastic force of the return spring, the telescopic rod shortens, causing the limiting rod to move. When the limiting rod moves, it can be inserted into the inside of the limiting tube, thereby fixing the collection tray between the limiting plates and preventing the collection tray from shaking or falling off. The collection tray is used to collect dust and impurities that fall off during the unfolding of the fabric. It is easy to install and remove and has better practicality. Attached Figure Description

[0023] The following is in conjunction with the appendix Figure 1 - Figure 5 The present invention will be described in further detail below.

[0024] A fabric spreading mechanism for a fabric inspection machine, referring to Figure 1 - Figure 5 The system includes a support frame 1, with two sets of guide rollers 2 installed at both ends of the top of the support frame 1. A support frame 3 is installed at one end of the top of the support frame 1. Two fixing ears 4 are symmetrically installed at the bottom of the support frame 3. A rotating shaft 5 is installed on each fixing ear 4. A spreading roller 6 is installed at one end of the rotating shaft 5. A support frame 7 is installed at the top of the support frame 1 away from the support frame 3. Two rotating rods 8 are installed between the inner side walls of the support frame 7. Several striking blocks 9 are installed on the outer ring surface of the rotating rods 8. Limiting plates 10 are installed at both ends of the bottom of the support frame 1 and below the striking blocks 9. A collection tray 11 is installed at the bottom of the support frame 1 and between the two limiting plates 10.

[0025] Reference Figure 1 - Figure 2 A connecting frame 12 is installed on one end of the support frame 3. A first drive motor 13 is installed on the outside of the connecting frame 12. The output shaft of the first drive motor 13 is connected to a rotating shaft 5 on one of the fixed ears 4. An active bevel gear 14 is installed on the rotating shaft 5 connected to the output shaft of the first drive motor 13. After the first drive motor 13 starts, its output shaft rotates, which drives the rotating shaft 5 connected to it to rotate. The active bevel gear 14 on the rotating shaft 5 also rotates. A driven bevel gear 15 is installed on one end of another rotating shaft 5. The active bevel gear 14 and the driven bevel gear 15 mesh with each other. The two spreading rollers 6 are vertically distributed and their included angle is consistent with the fabric conveying direction. When the active bevel gear 14 rotates, it will drive the driven bevel gear 15 to rotate because it meshes with the driven bevel gear 15. The rotation of the driven bevel gear 15 will then drive the other rotating shaft 5 to rotate, so that both spreading rollers 6 rotate. The fact that the two spreading rollers 6 are vertically distributed and their included angle is consistent with the fabric conveying direction can better spread the fabric.

[0026] Reference Figure 1 - Figure 3 One end of the rotating rod 8 extends through the outside of the support frame 7 and is fitted with a pulley 16. The two pulleys 16 are connected by a transmission belt 17. A fixed frame 18 is installed on the outside of the support frame 7. A second drive motor 19 is installed on the inner side wall of the fixed frame 18. The output shaft of the second drive motor 19 is connected to one of the pulleys 16. After the second drive motor 19 is started, its output shaft rotates, which drives the pulley 16 connected to it to rotate. This pulley 16 drives the other pulley 16 to rotate through the transmission belt 17, which in turn drives the two rotating rods 8 to rotate, causing the striking block 9 to rotate and strike the fabric, further assisting in the unfolding of the fabric.

[0027] Reference Figure 4 - Figure 5 The bottom outer side of the limiting plate 10 is provided with a groove 1001. Limiting blocks 20 are provided at both ends of the collection tray 11 inside the groove 1001. Limiting tubes 21 are installed on the outside of each limiting block 20. The limiting blocks 20 at both ends of the collection tray 11 can be placed into the groove 1001 at the bottom outer side of the limiting plate 10. Telescopic rods 22 are installed on both sides of the limiting plate 10 inside the groove 1001. Return springs 23 are installed on the outer ring surface of the telescopic rods 22. A handle 24 is installed at one end of each telescopic rod 22. A limiting rod 25 is installed on the outside of the handle 24 between the two telescopic rods 22. When the collection tray 11 needs to be installed, the handle 24 is pulled, and the handle 24 drives the telescopic rods 22. As the retractor extends, the return spring 23 is stretched, and the limiting block 20 of the collecting tray 11 is placed into the groove 1001. After releasing the handle 24, the telescopic rod 22 shortens under the elastic force of the return spring 23, which drives the limiting rod 25 to move. The outer ring size of the limiting rod 25 is matched with the inner wall size of the limiting tube 21, and the limiting rod 25 can be inserted into the inside of the limiting tube 21 when it moves, thereby fixing the collecting tray 11 between the limiting plates 10 to prevent the collecting tray 11 from shaking or falling off. When it is necessary to remove the collecting tray 11, pull the handle 24 again to move the limiting rod 25 out of the limiting tube 21, and the collecting tray 11 can be taken out. The collecting tray 11 is used to collect dust and impurities that fall off during the process of the fabric being beaten and unfolded.

[0028] Reference Figure 1 Both ends of the outer sides of the support frame 1 are equipped with C-shaped frames 26. The top of the C-shaped frame 26 is equipped with a fastening bolt 27. One end of the fastening bolt 27 extends to the inner side of the C-shaped frame 26 and is equipped with a limiting clamp 28. The outer ring surface of the fastening bolt 27 is threadedly connected to the inside of the C-shaped frame 26. After the C-shaped frame 26 is clamped on the outer frame of the fabric inspection machine, the fastening bolt 27 is rotated. Since the fastening bolt 27 is threadedly connected to the inside of the C-shaped frame 26, the fastening bolt 27 will move downward, driving the limiting clamp 28 to move downward, thereby clamping the device on the outer frame of the fabric inspection machine, realizing the installation and fixation of the device.

[0029] The implementation principle of the fabric spreading mechanism for a fabric inspection machine according to this utility model embodiment is as follows: When using this mechanism, after the U-shaped frame 26 is clamped onto the external frame of the fabric inspection machine, the fastening bolt 27 is rotated. Since the fastening bolt 27 is connected to the internal thread of the U-shaped frame 26, the fastening bolt 27 will move downward, driving the limiting clamp 28 to move downward, thereby clamping the device onto the external frame of the fabric inspection machine, realizing the installation and fixation of the device. The two sets of guide rollers 2 are used to guide the fabric to be conveyed along a specific path. After the second drive motor 19 is started, its output shaft rotates. The drive motor 13 rotates the connected pulley 16, which in turn drives another pulley 16 via the transmission belt 17. This, in turn, drives the two rotating rods 8 to rotate, causing the striking block 9 to rotate and strike the fabric, further assisting in the unfolding of the fabric. After the first drive motor 13 starts, its output shaft rotates, driving the connected rotating shaft 5 to rotate. The driving bevel gear 14 on the rotating shaft 5 also rotates accordingly. When the driving bevel gear 14 rotates, it meshes with the driven bevel gear 15, causing the driven bevel gear 15 to rotate as well. The driven bevel gear 15 rotates, which in turn drives another rotating shaft 5 to rotate, causing both spreading rollers 6 to rotate. The two spreading rollers 6 are perpendicularly distributed and their included angle is the same as the fabric conveying direction, which can better spread the fabric. The limiting blocks 20 at both ends of the collecting tray 11 can be placed into the grooves 1001 at the bottom outer side of the limiting plate 10. When it is necessary to install the collecting tray 11, pull the handle 24. The handle 24 drives the telescopic rod 22 to extend, and at the same time the return spring 23 is stretched. After the limiting blocks 20 of the collecting tray 11 are placed into the grooves 1001, Release the handle 24, and under the elastic force of the return spring 23, the telescopic rod 22 shortens, driving the limiting rod 25 to move. When the limiting rod 25 moves, it can be inserted into the inside of the limiting tube 21, thereby fixing the collecting tray 11 between the limiting plates 10 to prevent the collecting tray 11 from shaking or falling off. When it is necessary to remove the collecting tray 11, pull the handle 24 again to move the limiting rod 25 out of the limiting tube 21, and the collecting tray 11 can be taken out. The collecting tray 11 is used to collect dust and impurities that fall off during the process of beating and unfolding the fabric, and its practicality is better.
