[0061] The material belt guide plate 201 is fixedly connected to the bracket 208, the bottom of the bracket 208 and the bottom of the first vertical fixed plate 202 are fixedly connected to the frame 1, and a material belt guide groove for guiding is provided on the material belt guide plate 201. A vertical support rod 209 is fixedly connected to one side of the top of the material belt guide plate 201, and a sensing rod 210 for detecting whether the material is fed is fixedly installed on the top of the vertical support rod 209. The sensing rod 210 is a prior art, and its structure and working principle are not repeated here.

[0062] The guiding mechanism 206 includes a second fixing plate 2061 fixedly connected to the top of the first transverse fixing plate 203, guide grooves 2062 are provided on both sides of the upper surface of the second fixing plate 2061, and fixing rods 2063 are fixedly connected on both sides of the upper surface of the second fixing plate 2061 and above the guide grooves 2062, a through groove is provided on the fixing rod 2063, and a pressure block 2064 is fixedly connected inside the through groove, and the bottom of the pressure block 2064 passes through the through groove and contacts with the top of the second fixing plate 2061. Through the provision of the guide groove 2062, the material belt can be easily introduced into the feeding mechanism 204, and a gap is left between the material belt and the inner top walls of the two fixing rods 2063 so as not to contact each other. By passing the bottom of the pressure block 2064 through the through groove, it can contact with the material belt to prevent the material belt from being offset during transmission.

[0063] The feeding mechanism 204 includes a first cylinder 2041 fixedly connected to the first vertical fixed plate 202, the output end of the first cylinder 2041 is fixedly connected to a push plate 2042, the top of the push plate 2042 is fixedly connected to an L-shaped connecting plate 2043, the end of the L-shaped connecting plate 2043 away from the push plate 2042 is provided with a mounting groove, the interior of the mounting groove is provided with a connecting block 2044, the L-shaped connecting plate 2043 is provided with two spring grooves connected to the mounting groove, the two spring grooves are respectively provided on the front and rear inner walls of the L-shaped connecting plate 2043, the front and rear side surfaces of the connecting block 2044 are fixedly connected to extension rods, and the extension rods extend to the inside of the spring grooves, a first spring is fixedly connected between the extension rod and the inner top wall of the spring groove, the extension rod is adapted to the spring groove, so that there will be no deviation when the extension rod moves up and down, and the bottom of the connecting block 2044 is fixedly connected with two push blocks 2045;

[0064] The material belt is introduced into the guide groove 2062 formed in the second fixed plate 2061 through the material belt guide groove of the material belt guide plate 201. When the material belt moves inside the guide groove 2062, the physical part of the material belt pushes the pushing block 2045 to move upward. When the pushing block 2045 moves upward, it drives the connecting block 2044 and the extension rod to move upward inside the spring groove to squeeze the first spring. After the physical part of the material belt passes through the pushing block 2045, the material belt no longer pushes the pushing block 2045 to move upward. At this time, the first spring is no longer squeezed and begins to reset. When resetting, the first spring drives the extension rod, the connecting block 2044 and the pushing block 2045 to reset so that the bottom end of the pushing block 2045 enters the through groove of the material belt. Since a number of through grooves with equal spacing are provided on the material belt, when the material belt is introduced into the pushing block 2045 through the guide groove 2062 and is away from the side of the material belt guide plate 201 by a suitable distance, the bottom end of the pushing block 2045 can be located in the through groove of the material belt.

[0065] Then start the first cylinder 2041 to drive the pushing plate 2042 to move away from the material belt guide plate 201. The pushing plate 2042 can drive the L-shaped connecting plate 2043 to move during the movement. The L-shaped connecting plate 2043 can drive the connecting block 2044 and the pushing block 2045 to move during the movement. Since the bottom end of the pushing block 2045 is located in the through groove of the material belt, the pushing block 2045 can drive the material belt to move toward the cutting mechanism 205 inside the guide groove 2062 during the movement.

[0066] The cutting mechanism 205 includes two second vertical fixing plates 2051 fixedly connected to the top of the first horizontal fixing plate 203, and a gap is left between the two second vertical fixing plates 2051 and the L-shaped connecting plate 2043, so that the L-shaped connecting plate 2043 can move. The tops of the two second vertical fixing plates 2051 are fixedly connected to the same second horizontal fixing plate 2052, and the top of the second horizontal fixing plate 2052 is fixedly connected to a lifting cylinder 2053. The output end of the lifting cylinder 2053 passes through the through hole provided in the second horizontal fixing plate 2052 and extends to the bottom of the second horizontal fixing plate 2052. The output end of the lifting cylinder 2053 is fixedly connected to the first lifting plate 2054, and the bottom of the first lifting plate 2054 is fixedly connected to a U-shaped plate 2055. The U-shaped plate 2055 is provided with a groove on the side away from the second vertical fixing plate 2051. A knife seat 2056 is fixedly connected inside the groove, an upper cutter 2057 is fixedly connected to the bottom of the knife seat 2056, a lower cutter is fixedly connected to the top of the first horizontal fixed plate 203, and the lower cutter is located directly below the upper cutter 2057, a knife slot is provided on the second fixed plate 2061, and the lower cutter can be installed on the top of the first horizontal fixed plate 203 through the provision of the knife slot, a spring cavity is provided inside the knife seat 2056, a second spring 2058 is fixedly connected to the inner top wall of the spring cavity, a pre-pressing block 2059 is fixedly connected to the bottom end of the second spring 2058, the pre-pressing block 2059 passes through the pressing block groove provided at the bottom end of the knife seat 2056 and extends to the bottom of the knife seat 2056, a material belt locating pin 20510 is connected to the middle part of the U-shaped plate 2055, and a material belt locating hole matching the material belt locating pin 20510 is provided on the upper surface of the second fixed plate 2061;

[0067] The first cylinder 2041 drives the push block 2045 to move the material strip in the guide groove 2062 toward the cutting mechanism 205 during the movement. The specific process is as follows:

[0068] When the pushing block 2045 passes through the two second vertical fixed plates 2051 and pushes the material strip to a suitable distance, the bottom of the material strip contacts the lower cutter, and the lifting cylinder 2053 is started to drive the first lifting plate 2054 to move downward. During the downward movement, the first lifting plate 2054 can drive the U-shaped plate 2055 to move downward. During the downward movement, the U-shaped plate 2055 can drive the material strip positioning pin 20510 to pass through the through hole on the material strip and be located in the material strip positioning hole opened on the top of the second fixed plate 2061, and the positioning effect is achieved under the cooperation of the material strip positioning pin 20510 and the material strip positioning hole;

[0069] Moreover, the U-shaped plate 2055 drives the knife seat 2056 to move downward during the downward movement, and the knife seat 2056 can drive the pre-pressing block 2059 to contact the material belt during the downward movement, and the material belt is pressed and limited under the action of the pre-pressing block 2059.

At the same time, the two mounting plates 2065 are in contact with both ends of the slide rail 2068, which can prevent the sliding block 2069 from detaching from the slide rail 2068.

[0073] Both sides of the second fixed plate 2061 are provided with sliding grooves for sliding the U-shaped plate 2055. The setting of the sliding grooves guides the movement of the U-shaped plate 2055 and prevents the U-shaped plate 2055 from deviating during the movement.
