Description

Technical Field

[0001] The utility model relates to the technical field of tentering machines, in particular to a tentering machine used for sofa fabric production. Background Art

[0002] In the production process of sofa fabrics, in order to maintain the flatness and beauty of the sofa fabrics and ensure their use effect and overall beauty on the sofa, a tentering machine will be used to stretch and shape the sofa fabrics so that the width of the weft width is consistent and the fabric surface is flat and beautiful, thus meeting this requirement. The tentering machine makes the sofa fabric soft by applying wet or dry heat treatment, and then uses the centering mechanism in the tentering machine to stretch both sides of the sofa fabric so that the sofa fabric remains flat and wrinkle-free. After the sofa fabric is cooled and dried, the sofa fabric hardens and then shapes to ensure that the fibers are fixed in a new form to prevent shrinkage. The fabric that has completed the shaping process is output and rolled up from the other end of the machine.

[0003] The patent with the current announcement number CN202576911U discloses a tentering machine, including a cloth feeding and cloth sealing adjustment system, a herringbone opening system, a centering system, a working platform system, a roller centering system, a cloth feeding system, an overfeeding and edge spreading system, a cloth feeding needle chain system, a tentering needle chain system, a rear tentering system, a tension control system and a cloth output and folding system, which are connected in sequence; the tension control system includes a tension sensor, a speed sensor, a controller and a frequency converter; the controller is electrically connected to the tension sensor and the speed sensor, and the frequency converter is electrically connected to the cloth output and folding system and the controller. The operating speed of the rear tentering machine and the cloth output and folding system is controlled by the tension control system to ensure the stability of the tension of the fabric between the rear tentering machine and the cloth output and folding system, thereby improving the quality of the fabric.

[0004] Although the above device solves the problem of unstable operation and unstable product quality of traditional stenter equipment, the following problems still exist:

[0005] When the existing tentering machine is in use, after the sofa fabric is centered by the centering mechanism, since both sides of the sofa fabric will be pulled during the centering process, the position of the sofa fabric may shift when it leaves the centering mechanism. The position shift may cause the sofa fabric to be unevenly stressed in subsequent handling and processing, resulting in excessive or insufficient local stretching of the fabric, causing fabric deformation. When the shifted sofa fabric passes through heating, cooling or other processing units, the different contact conditions may lead to uneven processing effects, such as different color depths, large differences in feel, etc., affecting the dimensional stability and appearance quality of the final product. Utility Model Content

[0006] In view of the deficiencies of the prior art, the utility model provides a tentering machine for sofa fabric production, so that the tentering machine can correct the deviation of the sofa fabric.

[0010] Furthermore, one end of the fixed plate away from the centering mechanism is rotatably connected to a tension roller, and the height of the deviation correction rod is lower than the height of the tension roller.

[0011] Furthermore, a fixing frame is fixedly connected to the middle of the connecting plate, and the motor is fixedly connected to the fixing frame.

[0012] Furthermore, the outer wall of the deviation correcting rod is rotatably connected to two rotating sleeves.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] like Figures 1 to 5 As shown, a tentering machine for sofa fabric production comprises a centering mechanism 1 and a cloth discharging roller 2 connected to the back side of the centering mechanism 1, two symmetrically arranged fixing plates 3 are fixedly connected to the top of the back side of the centering mechanism 1, a connecting plate 4 is fixedly connected between the two fixing plates 3, a motor 5 is fixedly connected to the middle of the surface of the connecting plate 4, the output shaft of the motor 5 passes through the connecting plate 4 and is fixedly connected to a deviation correcting rod 6, movable grooves 7 corresponding to the position of the deviation correcting rod 6 are opened on the surfaces of the two fixing plates 3, a detection component is connected to one side of the surface of the connecting plate 4, and the height of the deviation correcting rod 6 is lower than that of the cloth discharging roller 2.

[0023] like Figure 1 As shown, a tentering machine for sofa fabric production in the utility model is similar to the existing tentering machine structure, such as a tentering machine disclosed in the patent with announcement number CN202576911U. The main improvement of the utility model is that the tentering machine can correct the deviation of the sofa fabric, such as Figures 1 to 5As shown, when a tentering machine for sofa fabric production in the utility model is in use, when the sofa fabric deviates, according to the deviating direction of the sofa fabric, the motor 5 will intelligently control the correcting rod 6 to correct the deviation; when the sofa fabric deviates in the direction away from the detection component, the detection component will send a signal to the motor 5, so that the output end of the motor 5 controls the correcting rod 6 to rotate counterclockwise, at this time, the linear movement direction of the correcting rod 6 and the movement direction of the sofa fabric form an angle, and the friction force generated between the correcting rod 6 and the sofa fabric drives the sofa fabric to move and re-center; when the detection component detects that the sofa fabric has returned to the correct position, the correcting rod 6 will return to its original position, thereby realizing the correction work; the height of the correcting rod 6 is lower than the height of the cloth outlet roller 2, so that the sofa fabric can form an inclined surface between the correcting rod 6 and the cloth outlet roller 2, thereby ensuring that the correcting rod 6 is in full contact with the sofa fabric for correction.

[0024] By arranging the motor 5 and the correcting rod 6 behind the centering mechanism 1, and utilizing the mutual cooperation of the motor 5 and the correcting rod 6, the correction work of the sofa fabric is realized, thereby ensuring that the sofa fabric will not be partially stretched excessively or insufficiently in the subsequent treatment and processing, causing the fabric to be deformed, and also avoiding the problems of different color depths and large differences in feel caused by uneven treatment effects, thereby ensuring the dimensional stability and appearance quality of the final product.

[0025] like Figures 1 to 4 As shown, the detection component includes a visual sensor 8, a connecting rod 13 and a threaded sleeve 14. The visual sensor 8 is slidably connected to the surface of the connecting plate 4. A sliding groove 12 is provided on one side of the surface of the connecting plate 4. The connecting rod 13 is slidably connected in the sliding groove 12. The top end of the connecting rod 13 is fixedly connected to the bottom surface of the visual sensor 8. The bottom end of the connecting rod 13 is threadedly connected to the threaded sleeve 14. The top surface of the threaded sleeve 14 fits with the bottom surface of the connecting plate 4.

[0026] Specifically, by continuously photographing, detecting and comparing the edge of the sofa fabric through the visual sensor 8, the deviation of the sofa fabric can be detected and measured, thereby facilitating the motor 5 to accurately control the correction rod 6 to correct the deviation; by using the connecting rod 13 and the sliding groove 12, the staff can adjust the position of the visual sensor 8 according to the sofa fabrics of different widths to achieve more accurate deviation detection; the threaded sleeve 14 can provide fixation for the visual sensor 8 to prevent the visual sensor 8 from moving, resulting in errors in the measurement results and affecting the correction work.

[0027] like Figure 4 As shown, the outer wall of the threaded sleeve 14 is fixedly connected to two symmetrically arranged rotating plates 15.

[0028] Specifically, the rotating plate 15 can bring convenience to the staff in rotating the threaded sleeve 14, and the threaded sleeve 14 can be moved without complicated operations or tools, which makes it convenient for the staff to tighten the threaded sleeve 14 and achieve more stable fixation of the visual sensor 8.

[0029] like Figure 1 , Figure 2 and Figure 3 As shown, one end of the fixed plate 3 away from the centering mechanism 1 is rotatably connected to a tension roller 9 , and the height of the deviation correction rod 6 is lower than that of the tension roller 9 .

[0030] Specifically, the cloth outlet roller 2, the correcting rod 6 and the tension roller 9 will make the sofa cloth form a V-shaped structure, thereby ensuring that both ends of the correcting rod 6 are in full contact with the sofa cloth, thereby performing the correcting operation more effectively. The full contact not only improves the accuracy of the correcting, but also enhances the stability and reliability of the correcting, thereby improving the correcting efficiency of the correcting rod 6.

[0031] like Figure 1 , Figure 2 and Figure 3 As shown, a fixing frame 10 is fixedly connected to the middle of the connecting plate 4 , and the motor 5 is fixedly connected to the fixing frame 10 .

[0032] Specifically, the fixing bracket 10 can fix the motor 5 to prevent the motor 5 from shaking or deflecting, thereby ensuring the movement accuracy and reliability of the correction rod 6, thereby improving the accuracy and efficiency of the correction work.

[0033] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the outer wall of the deviation correcting rod 6 is rotatably connected to two rotating sleeves 11.

[0034] Specifically, the provision of the rotating sleeve 11 can reduce the wear of the correcting rod 6 on the sofa fabric, and protect the sofa fabric from unnecessary damage.

[0035] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention.
