DETAILED DESCRIPTION

[0027] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0028] like Figure 1-7 The unwinder roll stand cloth placing device shown includes a roll stand body 1 and a chain conveyor 2. A slideway 21 for conveying the cloth roll from the chain conveyor 2 to the roll stand body 1 is connected between the chain conveyor 2 and the roll stand body 1. A cloth spreading mechanism is arranged on the slideway 21. When the cloth roll is conveyed on the slideway 21, the cloth spreading mechanism unfolds the cloth head of the cloth roll.

[0029] The cloth roll is then manually lifted to a height above the main body 1 of the roll stand and then lowered into the recessed area of ​​the main body 1 of the roll stand. The cloth roll is then turned over to find the cloth head and pulled out so that it can be placed on the winder later. This single cloth transporting method is time-consuming and labor-intensive, and is not conducive to the development of work. The device is equipped with a chain plate conveyor 2, so that cloth rolls can be placed in batches at its upper end and connected to the central control console. Then, a slide 21 is set between the chain plate conveyor 2 and the roll stand main body 1, and then a cloth roll is transported into the roll stand main body 1 each time through the central control console. The cloth roll slides into the roll stand main body 1 through the slide 21. During its sliding process, the spreading mechanism will automatically unfold the cloth head on the cloth roll, so that after the cloth roll falls into the main body 1 of the roll stand, the cloth head will be spread on the slide 21, which is convenient for workers to pull it out and connect it to the winder, thereby improving the overall work efficiency.

[0030] In one embodiment, the cloth spreading mechanism includes a passive component that follows the movement of the cloth roll, a cloth turning component for turning over the cloth head on the cloth roll, and a transmission component arranged between the passive component and the cloth turning component. The passive component is used to drive the cloth roll to roll when it is transmitted on the slide 21, and then transmit the information to the cloth turning component through the transmission component, thereby achieving the effect of automatically turning over the cloth head on the cloth roll during the transmission process of the cloth roll.

[0031] In one embodiment, side plates 22 are provided on both sides of the slide 21, and a first limiting slide groove 23 parallel to the slide 21 is provided on the side plates 22. The driven component includes a first limiting slider 3 that slides in the first limiting slide groove 23, a bearing frame 31 provided on the first limiting slider 3, and driven rollers 33 that are rotatably provided on the bearing frame 31 through movable shafts 32 at both ends; the surface of the driven roller 33 is covered with rubber, and when the cloth roll is transmitted on the slide 21, it rolls, and the cloth roll contacts the driven roller 33 and pushes it to slide downward. When sliding downward, it rubs against the surface of the driven roller 33 through rolling, thereby driving the driven roller 33 to rotate at the same time.

[0032] In one embodiment, the cloth turning assembly includes a connecting arm 4 arranged on the first limiting slider 3, a connecting frame 41 arranged at the end of the connecting arm 4 away from the first limiting slider 3, and cloth turning rollers 42 rotatably arranged on the connecting frame 41 at both ends, and the transmission assembly includes a first pulley 5 arranged on the movable shaft 32 of the driven roller 33, a second pulley 51 rotatably arranged on the bearing frame 31, a transmission belt 52 sleeved on the first pulley 5 and the second pulley 51, a driving gear 53 arranged at the end of the second pulley 51 away from the bearing frame 31, and a driven gear 54 arranged at both ends of the cloth turning roller 42 and meshing with the driving gear 53, and the cloth roll is transmitted on the slide 21. When the cloth roll is in motion, the cloth turning roller 42 and the driven roller 33 will contact the upper and lower surfaces of the cloth roll respectively, and then the cloth roll drives the driven roller 33 to rotate, and the driven roller 33 rotates synchronously with the first pulley 5, and then transmits the power to the second pulley 51 through the transmission belt 52, so that the driving gear 53 rotates, and then the driving gear 53 transmits the power to the cloth turning roller 42 through the driven gear 54, thereby driving the cloth turning roller 42 and the driven roller 33 to rotate in opposite directions. When the cloth roll is rolling, its cloth head position will pass through the cloth turning roller 42, and the cloth turning roller 42 will turn up the cloth head and separate it from the main body of the cloth roll by rotation, and then the cloth roll rolls and partially unfolds the front end, thereby achieving the effect of automatic spreading.

[0033] In one embodiment, a sinking slide groove 6 connected to the first limiting slide groove 23 is provided at the bottom end thereof, a first spring 61 is provided in the sinking slide groove 6, and a receiving plate 62 is provided on the first spring 61. When the cloth roll drives the driven roller 33 to slide to the bottom end of the slideway 21, in order to prevent the driven roller 33 from blocking the cloth roll from sliding into the roll rack body 1, a first spring 61 is provided. Therefore, when the first limiting slider 3 slides to the bottom end of the first limiting slide groove 23, the cloth roll exerts pressure on the driven roller 33 to drive the first limiting slider 3 downward into the sinking slide groove 6, thereby causing the driven roller 33 to move downward, so that it does not hinder the cloth roll.

[0034] In one embodiment, the connecting frame 41 includes a fixed arm 7 which is arranged at one end of the connecting arm 4 away from the first limiting slider 3 and is connected to the bearing of the movable shaft 32 on the driven roller 33, and a movable arm 71 which is limited and slides on the fixed arm 7 and is connected to the bearing of the cloth turning roller 42. The fixed arm 7 is provided with a movable groove 8, and the movable arm 71 slides in the movable groove 8. The two sides of the movable groove 8 are provided with second limiting sliders 81. The two sides of the bottom end of the movable arm 71 are provided with second limiting sliders 82 which are slidably engaged with the second limiting sliders 81. A second spring 83 is provided between the movable arm 7 and the movable arm 71. When the cloth roll slides to the bottom end of the slideway 21, the driven roller 33 moves downward to release the obstruction to the cloth roll, and then it also abuts against the cloth turning roller 42, so that it has an upward force along the axis of the movable arm 71, so that the movable arm 71 slides upward in the movable groove 8, thereby increasing the distance between the cloth turning roller 42 and the driven roller 33, and then the cloth roll passes between the two and enters the roll rack body 1. After the cloth roll passes, the movable arm 71 is reset under the action of the second spring 83.

[0035] In one embodiment, a terminal block 9 is provided at one end of the first limit slider 3 away from the bearing frame 31, a spring spring 91 is provided on the outer surface of the slideway 21, a winding roller 92 is installed on the spring spring 91, a connecting rope 93 is wound around the winding roller 92, and one end of the connecting rope 93 away from the winding roller 92 is fixed to the terminal block 9. When the cloth roll drives the driven roller 33 to slide downward, it pulls the connecting rope 93 through the terminal blocks 9 provided at both ends, so that the winding roller 92 is unwound, and energy is stored in the spring spring 91. While storing energy, 91 will also cause the driven roller 33 to generate resistance to the cloth roll, thereby slowing down the falling speed of the cloth roll and making it smoothly transmitted on the slide 21. When the cloth roll falls into the roll rack body 1, the clockwork spring 91 will drive the winding roller 92 to wind it, and then pull the first limit slider 3 to slide upward in the first limit slide groove 23 through the connecting rope 93 to complete its reset. During the reset process, the driven roller 33 will also generate a slight upward traction force on the cloth head unfolded at its upper end, so that the cloth head is spread out evenly on the slide 21.

[0036] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
