[0020] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in combination with the following embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0021] like Figure 1As shown, a large-bin cotton mixing box includes a body 1 and a conveyor belt 3 arranged on the body 1. A mixing bin 2 is fixedly connected to the upper side of the body 1 and the rear end located on the upper side of the conveyor belt 3. The mixing bin 2 consists of a casing and a fiber mixing mechanism arranged inside the casing. A feed port 4 is provided at the front end of the conveyor belt 3. When the fiber is placed at the front end of the upper side of the conveyor belt 3, the fiber can be input into the interior of the mixing bin 2 through the feed port 4 by starting the conveyor belt 3, and then the mixing process can be carried out inside the mixing bin 2.

[0022] The core of the present technical solution is that a lifting door body is installed inside the mixer bin 2 near the feed port 4, and the lower height of the lifting door body is adjustable. The space between the lower part of the lifting door body and the conveyor belt 3 is an effective entrance and exit. At this time, by starting the lifting door body to adjust the lower height of the lifting door body, the height of the effective entrance and exit can be adjusted to adapt to fiber piles of different heights.

[0023] Furthermore, in order to reduce the contact between the fiber pile and the lifting door body when it moves, and to reduce the fiber shedding phenomenon caused by the contact between the lifting door body and the moving fiber pile, an infrared ranging unit is installed on the front side of the lower part of the lifting door body. The lower limit height of the effective detection area of ​​the infrared ranging unit is lower than the lower end height of the lifting door body. A control host is installed on the mixing chamber 2. The infrared ranging unit and the lifting door body are electrically connected to the control host. The infrared ranging unit is set to detect whether there is an obstacle (fiber) within a set distance (10CM) in front of it. If there is an obstacle, the control host controls the lower end of the lifting door body to rise and increase the height of the effective entrance and exit. If there is no obstacle, the control host controls the lower end of the lifting door body to descend and lower the height of the effective entrance and exit, so that the lifting door body can automatically adjust the height of the effective entrance and exit according to the height of the fiber pile, thereby reducing the contact between the fiber pile and the lifting door body when it moves.

[0024] Among them, Figure 1-3 As shown, the lifting door body includes a transmission motor 5 fixedly connected to the outside of the mixing chamber 2, the output end of the transmission motor 5 is fixedly connected to a winding roller 6 rotatably connected to the upper front end of the mixing chamber 2, and a soft cloth piece 7 is wound on the outer side of the winding roller 6, and the end of the soft cloth piece 7 away from the winding roller 6 is the lower end of the lifting door body. At this time, the winding roller 6 can be driven to rotate by starting the transmission motor 5. When the winding roller 6 rotates, the soft cloth piece 7 will be wound or unwound. When the winding roller 6 rolls up the soft cloth piece 7, the lower end of the lifting door body is driven to rise, and when the winding roller 6 unwound the soft cloth piece 7, the lower end of the lifting door body is driven to drop, thereby relatively simply adjusting the height of the lower end of the lifting door body, and the height adjustment range is relatively large.

[0025] At the same time, if Figure 2-4As shown, in order to reduce the force deviation phenomenon of the soft cloth piece 7, the end of the soft cloth piece 7 away from the winding roller 6 is fixedly connected with a guide plate 8, and the front ends of the inner walls on both sides of the mixing chamber 2 are provided with vertical guide grooves 13, and the two ends of the guide plate 8 are respectively vertically slidably connected inside the two vertical guide grooves 13. Through the setting of the guide plate 8, the end of the soft cloth piece 7 can be vertically guided to reduce the deviation of the end of the soft cloth piece 7.

[0026] like Figure 2-3 As shown, the infrared distance measuring unit includes a plurality of infrared distance measuring sensors 12 mounted on the front side of the guide plate 8 in a horizontally equidistant array. At this time, the detection range of the infrared distance measuring unit can be effectively improved by using the plurality of infrared distance measuring sensors 12, so that the fiber pile can be effectively detected.

[0027] Moreover, in order to improve the detection accuracy of the infrared ranging sensor 12, a horizontal moving member is installed on the front side of the guide plate 8, and a plurality of slide seats 11 slidably connected to the front side of the guide plate 8 are installed on the horizontal moving member. The plurality of infrared ranging sensors 12 are respectively fixedly connected to the front sides of the plurality of slide seats 11. When the horizontal moving member drives the slide seat 11 to move horizontally, the infrared ranging sensor 12 can be driven to move together by the slide seat 11. By moving the infrared ranging sensor 12, the detection area of ​​the infrared ranging sensor 12 can be adjusted, thereby reducing the detection blind spot of the infrared ranging sensor 12 and improving the detection accuracy of the infrared ranging sensor 12.

[0028] Specifically, the horizontal moving part includes a transmission motor 9 fixedly connected to one end of the front side of the guide plate 8, and the output end of the transmission motor 9 is fixedly connected to a horizontally arranged screw rod 10, and the screw rod 10 and the slide seat 11 are threadedly connected. When the transmission motor 9 drives the screw rod 10 to rotate, the slide seat 11 can be driven by the screw rod 10 to move horizontally on the front side of the guide plate 8.

[0029] The working principle of the utility model is as follows: the fiber is placed at the front end of the upper side of the conveyor belt 3, and the conveyor belt 3 can be started to input the fiber into the interior of the mixing machine bin 2 through the feed port 4. When the conveyor belt 3 drives the fiber to move, it will detect whether there is fiber within the set distance in front of it through the infrared ranging unit. If there is fiber, the control host controls the transmission motor 5 to drive the winding roller 6 to rotate, so that the winding roller 6 can rewind the soft cloth piece 7, so that the lower end of the lifting door body rises and the height of the effective entrance and exit is increased. If there is no fiber, the control host controls the transmission motor 5 to drive the winding roller 6 to rotate again, so that the winding roller 6 can unwind the soft cloth piece 7, so that the lower end of the lifting door body drops and the height of the effective entrance and exit is lowered.

[0030] In summary, the technical solution can automatically adjust the height of the lower end of the lifting door body according to the height of the fiber pile by providing a lifting door body and an infrared ranging unit located on the lower side of the front end of the lifting door body, thereby reducing the contact between the fiber pile and the lifting door body during movement, reducing the fiber shedding phenomenon caused by the contact between the lifting door body and the fiber pile, and reducing the gap between the lifting door body and the fiber pile.

[0031] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
