DETAILED DESCRIPTION

[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] Reference Figure 1-5The raw material conveying equipment of the hot-cut bag-making machine comprises a base 1, a support frame 3 is installed on the base 1, a lifting screw 4 is arranged between the base 1 and the support frame 3 through a lifting motor 5, a lifting nut 13 is threadedly sleeved on the outer wall of the lifting screw 4 through a first limiting mechanism, and two connecting rods 11 are arranged on the lifting nut 13 through a fixing mechanism, a lifting frame 6 is arranged above the base 1, a connecting groove 12 corresponding to the connecting rod 11 is arranged on the lifting frame 6, an extrusion groove 14 is arranged on the connecting rod 11, a positioning rod 15 is arranged in the extrusion groove 14 through an extrusion mechanism, a positioning hole is arranged on the lifting frame 6, a double-headed screw 7 is arranged on the lifting frame 6 through an adjusting motor 8, and an adjusting plate 9 is threadedly sleeved on the outer walls of both ends of the double-headed screw 7 through a second limiting mechanism, and a limiting sleeve 10 is arranged on the adjusting plate 9 through an opening.

[0023] The first limiting mechanism includes a vertical limiting rod arranged between the support frame 3 and the base 1. The vertical limiting rod slides through the lifting nut 13. The vertical limiting rod is parallel to the lifting screw 4, which limits the lifting nut 13 to prevent it from rotating with the lifting screw 4.

[0024] The fixing mechanism includes a fixing block arranged on the connecting rod 11, and the two contacting fixing blocks are connected by fixing bolts. The contact surface between the connecting rod 11 and the lifting nut 13 is arc-shaped and provided with anti-slip grooves.

[0025] The extrusion mechanism includes a spring arranged in the extrusion groove 14, and both ends of the spring are elastically connected to the outer wall of the positioning rod 15 and the inner wall of the extrusion groove 14 respectively. The spring can realize the extrusion of the positioning rod 15 and can squeeze it into the positioning hole.

[0026] The second limiting mechanism includes a transverse limiting rod arranged on the lifting frame 6 , and the transverse limiting rod slides through the two adjustment plates 9 . The transverse limiting rod limits the adjustment plate 9 to prevent it from rotating together with the double-headed screw 7 .

[0027] A push rod 2 is installed on the base 1. The push rod 2 is tilted, which makes it convenient for operators to push and pull to transport raw materials. A plurality of moving wheels are installed at the bottom of the base 1.

[0028] When the utility model is used, the lifting motor 5 can drive the lifting screw 4 to rotate, and then the lifting nut 13 on its outer wall drives the lifting frame 6 to descend with the help of the connecting rod 11, and the two adjusting plates 9 are on both sides of the material roller body. Then the adjusting motor 8 is started to drive the double-headed screw 7 to rotate, and then the adjusting plate 9 is close to the material roller body, and the material roller body passes through the opening on the adjusting plate 9 and finally enters the limiting sleeve 10. Then the lifting motor 5 reverses to lift the material roller body to a certain height, and then the push rod 2 is used to push the device as a whole to perform moving and transportation operations. After arriving at the destination, the material roller body is lowered to the hot cutting machine support assembly, and then the two adjusting plates 9 are separated from the material roller body.
