DETAILED DESCRIPTION

[0016] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0017] like Figure 1As shown, a bottom glue machine comprises a frame 1, on which a fixed glue coating roller 2 is arranged horizontally, and the frame 1 is also movably connected with a plurality of adjustment brackets 3 located on both sides of the glue coating roller 2, and the adjustment bracket 3 is provided with a freely rotating material guide roller 4, and the material guide roller 4 is arranged parallel to the glue coating roller 2, and the frame 1 is provided with a plurality of adjustment mechanisms 5 with the same number as the adjustment bracket 3, each of the adjustment mechanisms 5 is transmission-connected with the corresponding adjustment bracket 3 and can drive it to approach or move away from the adjacent material guide roller 4 or the glue coating roller 2, and each of the adjustment brackets 3 is also provided with a positioning trigger mechanism 6 fixed on the frame 1 on the side away from the adjustment mechanism 5, and the positioning trigger mechanism 6 is set according to the spacing between two adjacent material guide rollers 4 and between the material guide roller 4 and the glue coating roller 2, and in the process of adjusting the material guide roller 4, after the adjustment bracket 3 moves a distance, the positioning trigger mechanism 6 is acted upon by the adjustment bracket 3 so that the adjustment mechanism 5 stops moving, thereby avoiding the excessive adjustment of the material guide roller 4;

[0018] Each adjustment bracket 3 is driven to move by its corresponding adjustment mechanism 5, so that each material guide roller 4 has an independent adjustment mode, and can accurately adjust different material guide rollers 4 to a suitable position according to needs, and at the same time, each material guide roller 4 is limited in its adjustment range by an independent positioning trigger mechanism 6;

[0019] Specifically, the adjustment bracket 3 includes a U-shaped mounting seat 301, a rotating rod 302 with one end fixedly connected to the mounting seat 301, the guide roller 4 is rotatably connected inside the mounting seat 301, the middle part of the rotating rod 302 is rotatably connected to the frame 1 and its rotation axis is parallel to the guide roller 4, and the other end of the rotating rod 302 is transmission-connected to the adjustment mechanism 5;

[0020] The adjusting mechanism 5 drives the rotating rod 302 to rotate, and the rotating rod 302 drives the mounting seat 301 to rotate. When the mounting seat 301 rotates forwards and reversely, it drives the material guide roller 4 to approach or move away from the adjacent material guide roller 4 and the glue coating roller 2;

[0021] In order to stably adjust the guide roller 4, in a further embodiment, the adjustment mechanism 5 includes a telescopic member 501. In this embodiment, the telescopic member 501 is a servo telescopic cylinder. One end of the telescopic member 501 is rotatably connected to the end of the rotating rod 302 away from the mounting seat 301. The cylinder body of the servo telescopic cylinder is rotatably connected to the rotating rod 302. The other end of the telescopic member 501 is rotatably connected to the frame 1. The end of the telescopic rod of the servo telescopic cylinder is rotatably connected to the frame 1. The rotation axes of both ends of the telescopic member 501 are parallel to the guide roller 4.

[0022] The telescopic rod of the servo telescopic cylinder can keep a fixed position after the adjustment is completed, so that the position of the guide roller 4 is fixed;

[0023] Specifically, Figure 2 , Figure 3 As shown, the positioning trigger mechanism 6 includes a base 601 fixedly connected to the frame 1, and the base 601 is provided with a movable hole 602 facing the adjustment bracket 3, and the movable hole 602 is provided with a trigger rod 604 connected to the bottom of the hole through an elastic member 603. In this embodiment, the base 601 is also fixedly connected to a guide seat, and the guide seat is provided with a guide hole coaxial with the movable hole 602 and with a larger diameter. The trigger rod 604 includes a trigger portion located in the movable hole 602 and extending into the guide hole, and a guide portion located in the guide hole. The trigger part is sleeved with a rigid spring, one end of the rigid spring is connected to the guide part, and the other end is connected to the bottom of the guide hole. A trigger switch 605 is provided at the bottom of the movable hole 602. The adjusting bracket 3 can drive the trigger rod 604 to push the trigger switch 605 during the movement. During the movement of the adjusting bracket 3, the trigger rod 604 can be contacted and push the trigger rod 604 to move into the movable hole 602. After a certain displacement is generated, the trigger rod 604 acts on the trigger switch 605, so that the action of the adjusting mechanism 5 stops;

[0024] In order to ensure that the adjustment bracket 3 can accurately cooperate with the trigger rod 604, in a further embodiment, a transmission plate 303 in contact with the trigger rod 604 is fixedly connected to the adjustment bracket 3, and a limit transmission groove 304 is provided on the transmission plate 303. The trigger rod 604 can be loosely matched with the limit transmission groove 304, and the matching clearance is zero;

[0025] In order to reduce the resistance during relative movement between the transmission plate 303 and the trigger rod 604, in a further embodiment, one end of the trigger rod 604 close to the transmission plate 303 is rotatably connected to a pulley 305 that can enter into the transmission groove 304, and the rotation axis of the pulley 305 is parallel to the guide roller 4.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it.
