Description

Technical Field

[0001] This utility model relates to the field of textile technology, specifically to a feed roller guide and positioning frame for fabric feeding. Background Technology

[0002] In the field of textile technology, fabrics generally need to be processed by printing, dyeing, cutting and other processes. In order to facilitate the storage of fabrics, the greige fabric is rolled up onto the feed roller. Therefore, during processing, the greige fabric on the take-up roller needs to be pulled to the take-up roller, and the fabric on the feed roller is pulled outward by the rotation of the take-up roller.

[0003] For example, Chinese patent document CN221759045U discloses a rapid fabric feeding device for a fabric feeding machine, including a rotating bracket, fixed brackets installed on both sides of the rotating bracket, and the fixed brackets installed on the top of a base. A feeding roller shaft is installed inside the rotating bracket, a drive gear is installed on one side of the rotating bracket, a gear frame is installed on the side of the fixed bracket, and a transmission gear is installed inside the gear frame. The drive gear is installed inside the gear frame and is connected to the transmission gear. A first drive motor is installed on one side of the gear frame, and an adjusting roller shaft is installed on the top of the base.

[0004] In the above technical solution, the first drive motor can drive the drive gear to rotate through the transmission gear, thereby driving the rotating bracket to select on the fixed bracket, so that the feeding roller shaft stuck in the rotating bracket can be released, allowing the operator to quickly replace the feeding roller shaft and improve the efficiency of fabric feeding.

[0005] However, in actual use, it was found that when the take-up roller pulls the fabric on the feed roller outward, if the feed roller rotates too fast, it is easy for the feed roller to move around, resulting in the fabric being fed out discontinuously, affecting the stability of the fabric feeding process, and generating more noise. Summary of the Invention

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a guide and positioning frame for fabric feeding rollers, which can improve the stability of fabric feeding.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a fabric feeding roller guide and positioning frame, including a support frame, a connecting frame on the support frame, one end of the connecting frame being rotatably connected to the support frame, and the other end extending outward as a connecting end, the connecting end being provided with a rotatable pressure roller, the pressure roller being used to abut against the fabric wound on the feeding roller to radially position the fabric, the connecting frame being provided with a guide roller, the guide roller having movable positioning sleeves on both sides, the positioning sleeves moving to abut against the fabric pulled out on the feeding roller to axially position the fabric.

[0008] The present invention is further configured such that: a cylinder is provided between the support frame and the connecting frame, a connecting beam is provided below the support frame, the base of the cylinder is rotatably connected to the connecting beam, the output end of the cylinder is rotatably connected to the connecting frame, and the cylinder is used to drive the connecting frame to rotate around the connection point with the support frame as the rotation center.

[0009] The present invention is further configured such that: the guide roller includes a shaft and a sleeve, the two ends of the shaft are fixed to both sides of the connecting frame, and the sleeve is fitted around the outer periphery of the shaft.

[0010] The present invention is further configured such that: the positioning sleeve includes a positioning part and a moving part; the positioning part is fitted outside the sleeve and can slide along the sleeve; the moving part has a connecting flange on its surface; the connecting flange has a rotatable guide wheel; the shaft has an axially extending guide groove; the guide wheel is coupled to the guide groove and can form a rolling fit between the two.

[0011] The present invention is further configured such that: a bidirectional lead screw is provided on the inner side of the connecting frame, the two ends of the bidirectional lead screw are respectively rotatably connected to the two sides of the connecting frame, one end of the bidirectional lead screw extends outward as an extension end, the extension end is connected to a handwheel, the outer periphery of the positioning part is provided with an outwardly extending connecting part, the connecting part is fitted onto the end of the bidirectional lead screw and forms a threaded engagement with the end of the bidirectional lead screw.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] Because a rotatable pressure roller is provided at the connecting end, when the take-up roller pulls the fabric on the feed roller outward by winding, the pressure roller is pressed against the fabric wound on the feed roller to radially position the fabric, which can prevent the feed roller from shifting, improve the stability of the fabric feeding and reduce the noise generated.

[0017] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0019] like Figures 1 to 3 As shown, this utility model discloses a fabric feeding roller guide and positioning frame, including a support frame 1, a connecting frame 2 on the support frame 1, one end of the connecting frame 2 being rotatably connected to the support frame 1, and the other end extending outward as a connecting end, the connecting end being provided with a rotatable pressure roller 3, the two ends of the pressure roller 3 being rotatably connected to the connecting end through bearings, the pressure roller 3 being used to abut against the fabric being wound on the feeding roller to radially position the fabric. In this way, when the winding roller pulls the fabric on the feeding roller outward by winding, it can prevent the feeding roller from shifting, improve the stability of the fabric feeding and reduce the noise generated.

[0020] In this embodiment, a guide roller 4 is provided on the connecting frame 2. When the fabric on the feed roller is connected to the take-up roller, the guide roller 4 can support the fabric to prevent it from drooping and contacting the ground. The guide roller 4 includes a shaft 41 and a sleeve 42. The two ends of the shaft 41 are fixed to both sides of the connecting frame 2. The sleeve 42 is fitted around the shaft 41 and a clamp is fitted at the junction to axially position the sleeve 42. Thus, during the traction process, the friction generated by the fabric contacting the sleeve 42 can drive the sleeve 42 to rotate, thereby reducing the friction on the fabric and facilitating the traction of the fabric. Furthermore, movable positioning sleeves 5 are provided on both sides of the guide roller 4. The positioning sleeves 5 move to abut against the fabric pulled out from the feed roller to axially position the fabric, thereby further improving the stability of the fabric during feeding. In addition, the position of the positioning sleeves 5 on both sides can be adjusted to accommodate fabrics of different widths, thereby improving the overall applicability.

[0021] In this embodiment, the positioning sleeve 5 includes a positioning part 51 and a moving part 52. The positioning part 51 is fitted onto the sleeve 42 and can slide along the sleeve 42. The moving part 52 has a connecting flange 8 on its surface. The connecting flange 8 has a rotatable guide wheel 9. The shaft 41 has an axially extending guide groove 411. The guide wheel 9 is coupled to the guide groove 411 and can form a rolling fit between the two. When the positioning sleeve 5 is connected to the guide roller 4, the positioning can be quickly achieved by aligning the guide wheel 9 on the moving part 52 with the corresponding guide groove 411 on the shaft 41, thereby facilitating the connection between the positioning sleeve 5 and the guide roller 4.

[0022] In addition, a bidirectional lead screw 10 is provided inside the connecting frame 2. The two ends of the bidirectional lead screw 10 are rotatably connected to the two sides of the connecting frame 2 through bearings. One end of the bidirectional lead screw 10 extends outward as an extension end, and a handwheel 11 is connected to the extension end. The positioning part 51 has an outwardly extending connecting part 511 on its outer periphery. The connecting part 511 is fitted onto the end of the bidirectional lead screw 10 and forms a threaded engagement with the end of the bidirectional lead screw 10. When it is necessary to adjust the position of the positioning sleeve 5, the bidirectional lead screw 10 is driven to rotate by the handwheel 11, so that the positioning sleeve 5, which is fitted onto the end of the bidirectional lead screw 10 through the connecting part 511, can move along the direction of the bidirectional lead screw 10 under the guidance of the guide wheel 9 and the guide groove 411, thereby realizing the adjustment of the position of the positioning sleeve 5. Furthermore, during the movement of the positioning sleeve 5, the friction generated between the guide wheel 9 and the guide groove 411 is rolling friction, which can reduce the friction force on the positioning sleeve 5 during the movement, thereby facilitating the adjustment of the position of the positioning sleeve 5.

[0023] In this embodiment, a cylinder 6 is provided between the support frame 1 and the connecting frame 2. A connecting beam 7 is provided below the support frame 1. The base of the cylinder 6 is rotatably connected to the connecting beam 7, and the output end of the cylinder 6 is rotatably connected to the connecting frame 2. The cylinder 6 is used to drive the connecting frame 2 to rotate around the connection point with the support frame 1. When it is necessary to adjust the distance between the pressure roller 3 and the feed roller by rotating the connecting frame 2, the cylinder 6 can drive the connecting frame 2 to rotate around the connection point with the support frame 1 by extending and retracting the output end of the cylinder 6. This makes it easier to rotate the connecting frame 2.

[0024] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
