[0030] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention will be further described below with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other. For the convenience of narration, words such as "upper", "lower", "left" and "right" hereinafter only represent the same directions as the upper, lower, left and right directions of the drawings themselves, and do not limit the structure.

[0031] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the specific embodiments disclosed in the following specification.

[0032] Embodiment, as Figures 1-10As shown in the figure, a cloth discharging device of a pure cotton grey cloth loom provided by the present invention includes a loom cloth discharging conveyor belt 1. The loom cloth discharging conveyor belt 1 is arranged on a cloth discharging tail seat 2, and the cloth discharging tail seat 2 is connected to the loom. Above the conveying surface of the loom cloth discharging conveyor belt 1, a tensioning mechanism 3 is arranged. In the cloth discharging direction of the loom cloth discharging conveyor belt 1 and the tensioning mechanism 3, a cloth discharging frame 4 is arranged. A winding mechanism 5 is arranged on the cloth discharging frame 4. The loom cloth discharging conveyor belt 1 includes a horizontal section 11 and a downward inclined section 12. The tensioning mechanism 3 includes horizontal support seats 31 arranged on both sides of the horizontal section 11 and inclined support seats 32 arranged on both sides of the downward inclined section 12. A first tensioning roller 33 and a second tensioning roller 34 are respectively arranged on the horizontal support seats 31 and the inclined support seats 32. The winding mechanism 5 includes a pair of variable diameter roller groups 51 distributed in parallel with the first tensioning roller 33 and the second tensioning roller 34. The two variable diameter roller groups 51 are used to achieve centerless rolling support for the cloth roll 9 and can perform synchronous translation movements with the variable diameter roller groups 51. A pair of pedestal bearings 44 are arranged on the rotation center line of the variable diameter roller groups 51. Linkage mechanisms 6 for adjusting the distance between the two pedestal bearings 44 on the same side are arranged on both sides of the cloth discharging frame 4. A lifting oil cylinder 7 is arranged at the driving end of the linkage mechanism 6. One of the variable diameter roller groups 51 is driven by a winding drive motor. The winding drive motor transmits power to the central shaft 511 of the variable diameter roller group 51 through a driven gear, a driving gear, a tensioning gear, and a gear belt, as Figure 8 shown, the driven gear is arranged between the pedestal bearing 44 and the slider 61, and the winding drive motor, the driving gear, the tensioning gear, and the gear belt are arranged inside the cloth discharging frame 4.

[0033] Specifically, the cloth outlet part of the loom transmits the cloth from low to high to the horizontal section 11 of the cloth outlet transmission belt of the loom, and the cloth is transmitted from the horizontal section 11 along the lower inclined section 12 toward the winding mechanism 5. On the cloth transmission path, the tension of the cloth can be increased by turning. The first tensioning roller 33 of the tensioning mechanism 3 is used to avoid the cloth jumping. Moreover, the cloth is continuously fed from the second tensioning roller 34 to the rotating cloth roll 9, which is also a feature from low to high. Therefore, the cloth can also maintain a good tension at the connection part between the tensioning mechanism 3 and the winding mechanism 5, which can improve the cloth feeding effect. Furthermore, the woven cloth is fed into the winding mechanism 5 with a certain tension, and the winding mechanism 5 continuously winds the cloth into a roll by means of centerless support. There is no connection structure at both ends of the cloth roll 9, but the variable diameter roller group 51 is used to limit its left and right movement. The center of gravity of the cloth roll 9 finally rolled to a certain diameter is higher than the maximum limit level of the variable diameter roller group 51, so the difficulty of taking and placing the finished cloth roll 9 is relatively low, which is conducive to improving the efficiency of cloth output and collection. It should be noted that the cloth-making and cloth-discharging speed of a general loom is 3~5mm / min or 3~8m / min. In order to ensure the rolling and tightening of the whole set of cloth, the speed of the variable diameter roller group can be controlled to be greater than the cloth-discharging speed of the loom, and the differential effect can be used to achieve the tightening of the cloth; further, a hollow metal tube with a certain weight is used as the center of the cloth. In the initial stage of cloth discharging, the head end of the cloth is adhered to the hollow metal tube by the staff, and the two ends of the hollow metal tube are clamped by clamping plates. In addition, due to the gravity of the hollow metal tube, the cloth can be effectively maintained at the support center of the two variable diameter roller groups during the continuous rolling process, and there will be large up and down jumps. Moreover, as the thickness and weight of the cloth gradually increase, the cloth can maintain effective contact and support with the variable diameter roller group throughout the process, and effectively remain in the cloth collecting station, thereby completing the winding operation of the whole roll of cloth. Among them, the mass of the hollow metal tube in the center of the cloth is originally smaller than the solid roller used in the existing loom cloth outlet station. The mass of the solid roller with a width of 2m at the existing loom cloth outlet station is generally not less than 300kg. The hollow metal tube used in the present invention is mainly to meet the initial cloth collection requirements and the subsequent workshop transfer requirements of the cloth.

[0034] Furthermore, the lifting oil cylinder 7 can control the planar movement of the link mechanism 6. The movable end of the link mechanism 6 is connected to two pedestal bearings 44. Therefore, on the basis of the pedestal bearings 44 maintaining the support for the center of the variable-diameter roller set 51, the actual support span of the two variable-diameter roller sets 51 can be adjusted, and a reasonable change can occur in the triangular relationship among the driven gear, the driving gear, and the tensioning gear to ensure the continuous power of the winding drive motor to the variable-diameter roller set 51. Moreover, the real-time diameter of the variable-diameter roller set 51 itself can be adjusted. As the structure directly supporting the fabric roll 9, the change in its diameter also directly causes the change in the support span of the two variable-diameter roller sets 51, which can be applied to support the fabric roll 9 that becomes larger from smaller. In particular, it can avoid obvious head shaking and tail swinging when the volume of the fabric roll 9 increases due to the too small support span. Therefore, the winding mechanism 5 provided by the present invention can ensure the stability of the real-time winding action on the fabric outlet side of the equipment.

[0035] Such as Figures 7-10As shown, the variable diameter roller group 51 includes a central shaft 511, the shaft side of the central shaft 511 cooperates with the seat bearing 44, a pair of clamping plates 512 are arranged on the central shaft 511, and at least 8 first U-shaped openings 513 distributed in a circular array are arranged on the clamping plates 512, and a circular end plate 514 is arranged on one side of the clamping plates 512, and a plurality of second U-shaped openings 515 corresponding to the first U-shaped openings 513 are arranged on the end plate 514, and the first U-shaped openings 513 and the second U-shaped openings 515 are relatively distributed to form waist-shaped adjustment holes, and a plurality of A roller shaft 516 is matched with the waist-shaped adjustment hole one by one, and an umbrella frame assembly 52 is arranged on the central shaft 511 and is hingedly matched with the axial end of the roller shaft 516. The umbrella frame assembly 52 is movably nested with the central shaft 511 and a transmission flange 53 is arranged at its end. A transmission key 54 is arranged on the inner side of the transmission flange 53. A long strip hole movably matched with the transmission key 54 is arranged on the axial surface of the central shaft 511. A variable diameter transmission core shaft 55 which is transmission-connected to the transmission key 54 is arranged inside the central shaft 511, and a flexible stretching assembly 56 is arranged at the power input end of the variable diameter transmission core shaft 55. The rollers 516 all have shoulders, and the shoulders are against the end surface of the clamping plate 512. The clamping plate 512 provides a mounting node and a radial diameter-changing path for the rollers 516 on the one hand, and is used to limit the roll width of the cloth roll 9 on the other hand. The end plate 514 is installed on the clamping plate 512, so that the first U-shaped opening 513 and the second U-shaped opening 515 form a closed waist-shaped adjustment hole, so the end plate 514 can be used to control the maximum diameter-changing length of the diameter-changing roller group 51. The umbrella frame assembly 52 can slide along the central axis 511, and the umbrella frame assembly 52 A transmission relationship is established with the flexible stretching component 56 through the transmission flange 53, the transmission key 54 and the variable diameter transmission core shaft 55. If the flexible stretching component 56 drives the variable diameter transmission core shaft 55 to move along the middle position of the central axis 511, the transmission key 54 drives the umbrella frame component 52 to move toward the clamping disk 512, and the umbrella frame component 52 supports the roller shaft 516 to open along the waist-shaped adjustment hole. The center distance between the roller shaft 516 and the central axis 511 on the same variable diameter roller group 51 is pulled apart, so the diameter of the variable diameter roller group 51 can be adjusted.

[0036] Furthermore, the number of roller shafts 516 of the same variable-diameter roller group 51 corresponds to the number of waist-shaped adjustment holes, and the number is not less than 8. In this way, the roller shaft 516 can have sufficient support density within the adjustable range of the variable-diameter roller group 51, which is beneficial to increase the support pairs of the variable-diameter roller group 51 and the cloth roll 9. In particular, after the volume of the cloth roll 9 increases, a sufficient number of support pairs can ensure the stability of the continuous rolling of the cloth roll 9, so as to ensure the efficiency of cloth delivery and collection.

[0037] like Figure 1 , Figure 2 and Figure 10As shown, the umbrella frame assembly 52 includes a plurality of fork rods 521 and a sleeve 522. One end of the fork rod 521 is provided with a U-shaped opening 523 hinged to the shaft end of the roller shaft 516. The width of the fork rod 521 gradually narrows from the U-shaped opening to the other end of the fork rod 521. A fixed shaft 524 is provided at the other end of the fork rod 521. One end of the sleeve 522 is provided with a plurality of flap openings 525 for installing the fixed shaft 524, and the other end of the sleeve 522 is provided with a flange plate 526 for connecting with the transmission flange 53. Among them, the mating surface of the sleeve 522 and the central shaft 511 is a smooth surface to reduce relative translational friction; the flange plate 526 and the transmission flange 53 are connected by flange bolts to complete multi-node connection to ensure the connection reliability of the variable-diameter transmission path; the shape of the fork rod 521 adopts a design with a wider front and a narrower rear, which is not only the need for space planning but also the applicability requirement considering that the maximum diameter of the sleeve 522 is smaller than the maximum adjustable diameter of the roller shaft 516.

[0038] As Figure 7 , Figure 8 and Figure 9 shown, the variable-diameter transmission mandrel 55 is provided with a rotary joint 551 at one end far from the umbrella frame assembly 52. A sliding head 552 is provided at the end of the rotary joint 551. The sliding head 552 cooperates with a sliding plate 41 provided on the side of the fabric outlet frame 4. A chute for the sliding head 552 to perform translational movement is provided inside the sliding plate 41. Two pairs of guide rods 42 that are slidably matched with the sliding plate 41 are provided at both ends of the sliding plate 41, and the guide rods 42 are provided on the fabric outlet frame 4. If the flexible tension assembly 56 drives the sliding plate 41 to perform translational movement along the guide rods 42, the sliding plate 41 can drive the sliding head 552 to push the rotary joint 551 and the variable-diameter transmission mandrel 55 to move along the axial direction of the central shaft 511, so as to achieve the purpose of controlling the real-time diameter of the variable-diameter roller set 51. At the same time, the chute on the sliding plate 41 provides a path perpendicular to the moving direction of the variable-diameter transmission mandrel 55 for the sliding plate 41. In this way, when the link mechanism 6 adjusts the two variable-diameter roller sets 51, it does not affect the rotation condition of the variable-diameter roller set 51, and ensures that the flexible cable 563 assembly and the variable-diameter roller set 51 always maintain a ready-to-adjust state.

[0039] As Figure 1As shown in the figure, the flexible stretching assembly 56 includes a first pulley 561 disposed at the end of the skateboard 41, a second pulley 562 disposed at the end of the cloth outlet frame 4, and a wire pay-off wheel 564 disposed below the second pulley 562. A pulling rope 563 is disposed on the driving surfaces of the first pulley 561 and the second pulley 562. The end of the pulling rope 563 is disposed on the wire pay-off wheel 564. A wheel shaft is disposed at the center of the wire pay-off wheel 564, and a speed-reducing pay-off motor 565 is disposed at the driving end of the wheel shaft. The speed-reducing pay-off motor 565 is installed inside the cloth outlet frame 4. Considering from the aspect of space overall planning, the flexible stretching assembly 56 takes the cloth outlet frame 4 as the assembly basis and arranges the transmission path of the pulling rope 563 at reasonable nodes. Specifically, both ends of the pulling rope 563 are fixed on the wire pay-off wheel 564. It winds around the first pulley 561 for almost half a turn in a C shape. After winding, the two strands of the pulling rope 563 are both pressed into the wheel groove of the second pulley 562 from the same side. In this way, when the speed-reducing pay-off motor 565 drives the wire pay-off wheel 564 to rotate, the actual working length of the pulling rope 563 changes. In particular, it can cause the first pulley 561 to generate a translational movement, thereby driving the skateboard 41, the sliding head 552, and the variable-diameter transmission core shaft 55 to move along the parallel direction of the guide rod 42, and further achieving the purpose of controlling the real-time diameter of the variable-diameter roller set 51.

[0040] As Figure 1 , Figure 3 , Figure 5 and Figure 6 As shown in the figure, the link mechanism 6 includes a slider 61 nested and cooperated with two central shafts 511. The slider 61 is slidably disposed in a sliding opening formed on the cloth outlet frame 4. The link mechanism 6 further includes a first link 62 and a second link 63 disposed at the ends of the two central shafts 511. The first link 62 and the second link 63 are hinged and a hinge shaft 64 is disposed at the hinge center. The hinge shaft 64 is hinged with the telescopic end of the lifting oil cylinder 7. Among them, the slider 61 is rotationally cooperated with the central shaft 511. While the slider 61 makes a translational movement along the sliding opening, it can also drive the central shaft 511 to move, and ensure that in addition to the support of the pedestal bearing 44 on the axial side of the central shaft 511, there is also a second support, which can improve the working reliability of the variable-diameter roller set 51. The bottom of the lifting oil cylinder 7 is a fixed end, and its top is a telescopic end. If the lifting oil cylinder 7 drives the hinge shaft 64 to lift and lower, it can drive the horizontal lengths of the first link 62 and the second link 63 to change, and the first link 62 and the second link 63 also make planar movements around the central shafts 511 of the corresponding variable-diameter roller sets 51, thereby realizing the adjustment of the horizontal support span of the two variable-diameter roller sets 51.

[0041] As Figure 1 and Figure 5As shown in the figure, sliding holes corresponding to and communicating with the sliding ports are provided on both sides of the cloth outlet frame 4. A T-shaped pressing plate 65 is arranged in the sliding holes. The top surface of the T-shaped pressing plate 65 is located above the cloth outlet frame 4. The T-shaped pressing plate 65 and the slider 61 can move synchronously, thereby ensuring the stability of the passive adjustment and translational movement of the slider 61 and preventing large-range axial movement thereof.

[0042] As Figure 2 shown in the figure, a guiding port is provided at the bottom of the pedestal bearing 44, and a guiding track 43 connected to the cloth outlet frame 4 is arranged in the guiding port. By designing the guiding track 43, anti-jump protection can be provided for the pedestal bearing 44, so that while it moves along with the variable-diameter roller set 51, it has a stable supporting surface, and further enables the variable-diameter roller set 51 to always maintain a smooth rotation effect in the rotating state. The pedestal bearing can be installed at the bottom of the self-rotation driving source of the variable-diameter roller set. The self-rotation driving source such as a motor can transmit power to the central shaft of the variable-diameter roller set through a reduction gear set from top to bottom, realizing the self-rotation of the variable-diameter roller set and ensuring effective bearing support for the variable-diameter roller set.

[0043] As Figure 1 and Figure 5 shown in the figure, in order to protect the link mechanism 6 and other part structures, a pair of top covers 8 used to cover both sides of the cloth outlet frame 4 and the link mechanism 6 are provided above the cloth outlet frame 4 of the present invention. The top covers 8 prevent sundries from falling into the interior of the components of the device and causing equipment failures.

[0044] The above are only the preferred embodiments of the present invention, and are not limitations on the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
