[0020] 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 the embodiments.

[0021] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. Example

[0022] Reference Figure 1-Figure 8A slitting machine for producing ton bags includes a processing table 1, on which a plurality of guide rollers 2 are rotatably connected, a material setting frame 21 is fixedly connected to the processing table 1, and a feeding roller 22 is rotatably connected to the material setting frame 21, and also includes: a mounting frame 3, the mounting frame 3 is fixed to the top of the processing table 1, wherein both sides of the top of the mounting frame 3 are fixedly connected to electric push rods 31, and the bottom end of the telescopic part of the electric push rod 31 is provided with a cutting part for slitting the ton bag; a softening box 4, the softening box 4 is fixed to the inner wall of the mounting frame 3, and a heating pipe 41 is fixedly connected to the softening box 4, and the heat generated by the heating pipe 41 will The ton bags passing through the bottom of the softening box 4 are appropriately preheated to soften the ton bags, reduce their brittleness, facilitate subsequent cutting and reduce the generation of edge burrs, thereby improving the slitting quality of the ton bags; at the same time, after the ton bags are softened, under the rolling action of the feed roller 32, the ton bags can be flattened before slitting, ensuring that the surface of the ton bag material is flat and wrinkle-free, avoiding unevenness or deviation during the cutting process, and further improving the slitting quality; wherein, the output end of the softening box 4 is perpendicular to the travel direction of the ton bag, and the mounting frame 3 is provided with a guide portion for promoting the movement of the hot air flow in the softening box 4.

[0023] It should be noted that, during the slitting process, a material receiving platform is installed at one end of the processing table 1 close to the mounting frame 3. The material receiving platform can be a common flat table, etc., so as to store the ton bags cut off; Reference Figure 1-Figure 3 , wherein a plurality of feed rollers 32 are rotatably connected in the mounting frame 3, the feed rollers 32 are connected to the ends of the guide rollers 2 through a pulley set 33, a servo motor 34 is fixedly connected to the side wall of the mounting frame 3, and the rotating shaft of the servo motor 34 is fixedly connected to the rotating shaft end of the feed roller 32; the cutting part comprises a lifting plate 5, the top of the lifting plate 5 is fixed to the bottom end of the telescopic part of the electric push rod 31, and limiting slide grooves 51 are provided on both sides of the mounting frame 3, the lifting plate 5 slides up and down along the limiting slide grooves 51 on both sides, and a cutting knife 52 is fixedly connected to the bottom of the lifting plate 5.

[0024] It should be noted that the distance between the bottom center of the softening box 4 and the cutting knife 52 is equal to the length of the ton bag required to be cut each time.

[0025] Through the arrangement of the above structure, the servo motor 34 is turned on, and under the transmission action of the pulley group 33, the guide roller 2 and the feed roller 32 are driven to rotate, thereby pushing the ton bag to move along the surface of the processing table 1. When the ton bag moves forward a slitting distance, the servo motor 34 stops rotating. At this time, the telescopic end of the electric push rod 31 extends downward, so that the lifting plate 5 moves with the cutting knife 52 to the surface of the processing table 1. Finally, when the cutting knife 52 reaches the surface of the processing table 1, the single slitting of the ton bag is completed, and then the above process is repeated continuously to achieve continuous slitting of the entire roll of ton bags, thereby effectively improving the slitting efficiency; at the same time, since the distance between the bottom center of the softening box 4 and the cutting knife 52 is equal to the length of the ton bag required to be cut each time, the heat in the softening box 4 will centrally heat the next cutting area of ​​the ton bag during each slitting, thereby ensuring the heating effect, reducing the difficulty of subsequent slitting, and effectively improving the slitting quality.

[0026] Reference Figure 5-Figure 8 , wherein, piston bins 53 are fixedly connected to both sides of the processing table 1, a piston plate 531 is slidably connected in the piston bin 53, a push-pull rod 532 is fixedly connected to the top of the piston plate 531, and the other end of the push-pull rod 532 is fixedly connected to the end of the lifting plate 5, and an air suction pipe 54 is fixed and connected to the side wall of the piston bin 53, the air suction pipe 54 is connected to the inner cavity of the lifting plate 5, and a one-way valve is arranged in the air suction pipe 54, and a plurality of dust suction holes 55 facing the cutting knife 52 are evenly spaced at the bottom of the lifting plate 5; a filter box 56 is fixedly connected to the air suction pipe 54, the filter box 56 is connected to the air suction pipe 54, the bottom of the filter box 56 is inclined, and a dust filter plate 561 is fixedly connected to the connecting part of the inclined bottom of the filter box 56 and the air suction pipe 54.

[0027] It should be noted that the one-way valve in the air suction pipe 54 can only allow the gas around the dust suction hole 55 to enter the piston chamber 53 .

[0028] Through the arrangement of the above structure, when the push-pull rod 532 pulls the piston plate 531 to move upward, suction will be generated in the piston chamber 53, and the one-way valve in the suction pipe 54 will be opened, so that the suction will be transmitted along the suction pipe 54 and the inner cavity of the lifting plate 5 to the dust suction hole 55, thereby generating suction on both sides of the cutting knife 52, thereby absorbing the cutting dust attached to the cutting knife 52 and the remaining on the processing table 1, and finally trapped in the filter box 56 under the filtering action of the dust filter plate 561, thereby effectively improving the cleanliness of the cutting area and the surface of the cutting knife 52, thereby ensuring the slitting accuracy and improving the slitting quality.

[0029] Reference Figure 3 , Figure 4The guide part includes a guide bin 6, which is fixed on the top of the softening box 4 and is connected to the softening box 4. An air pressure plate 61 is slidably connected in the guide bin 6. A plurality of groups of spring telescopic rods 62 are fixed at equal intervals on the top of the softening box 4. The telescopic ends of the spring telescopic rods 62 penetrate into the guide bin 6 and are fixedly connected to the bottom of the air pressure plate 61. Both sides of the top of the guide bin 6 are fixedly connected with an inflation tube 63. The other end of the inflation tube 63 is connected to the inner cavity of the piston bin 53, and a one-way valve is arranged in the inflation tube 63.

[0030] It should be noted that the one-way valve in the inflation tube 63 can only allow the gas in the piston chamber 53 to enter the guide chamber 6 .

[0031] Through the arrangement of the above-mentioned structure, in the process of the lifting plate 5 being pushed downward, the piston plate 531 will be pushed to the bottom of the piston chamber 53 through the push-pull rod 532 at the same time, thereby compressing the gas in the inner cavity of the piston chamber 53 and opening the one-way valve in the inflation pipe 63, so that the compressed gas enters the guide chamber 6 along the inflation pipe 63, thereby increasing the air pressure in the guide chamber 6, and then pushing the air pressure plate 61 to move downward, thereby pushing the heated gas in the guide chamber 6 to pass through the heating pipe 41 and quickly approach the surface of the ton bag. Since the distance between the bottom center of the softening box 4 and the cutting knife 52 is equal to the length of the ton bag required to be cut each time, the downward moving heat flow will just quickly contact the cutting area of ​​the ton bag, thereby quickly heating the cutting area, ensuring that the cutting area is effectively softened, and improving the subsequent cutting quality.

[0032] Reference Figure 3 , Figure 4 and Figure 8 , wherein an exhaust box 7 is fixedly connected to the side wall of the guide bin 6, an exhaust pipe 71 is fixed and connected between the exhaust box 7 and the top of the inner cavity of the guide bin 6, and an electromagnetic valve is arranged in the exhaust pipe 71, and a plurality of groups of blowing holes 72 are evenly spaced on the side of the exhaust box 7 away from the guide bin 6, and the blowing holes 72 are inclined toward the top of the processing table 1; a recoil pipe 73 is fixed and connected to the top of the exhaust pipe 71, and the other end of the recoil pipe 73 is connected to the inner cavity of the inclined upper end of the filter box 56, and an electromagnetic valve is arranged in the recoil pipe 73. Magnetic valve; a limit plate 8 is fixedly connected to the outer wall of the end of the lifting plate 5, a contact groove 81 is opened on the top of the processing table 1, and a contact switch 82 is slidably connected in the contact groove 81, and a fitting spring 83 is fixedly connected between the contact switch 82 and the inner wall of the contact groove 81. The fitting spring 83 is used to ensure that the limit plate 8 and the contact switch 82 are tightly fitted to improve the contact effect, and at the same time facilitate the lifting and lowering movement of the limit plate 8, and the contact switch 82 is electrically connected to the recoil pipe 73 and the electromagnetic valve in the exhaust pipe 71.

[0033] It should be noted that when the limit plate 8 is in contact with the contact switch 82, the recoil pipe 73 and the solenoid valve in the exhaust pipe 71 are in an open state; when the limit plate 8 is disengaged from the contact switch 82, the recoil pipe 73 and the solenoid valve in the exhaust pipe 71 are in a closed state.

[0034] Through the above-mentioned structural setting, when the lifting plate 5 moves down to the bottom, the limit plate 8 will contact the contact switch 82, thereby opening the electromagnetic valves in the exhaust pipe 71 and the recoil pipe 73. At this time, the gas in the guide chamber 6 will be discharged along the exhaust pipe 71 and the recoil pipe 73, and the airflow in the exhaust pipe 71 will blow along the exhaust box 7 and the blowing hole 72 to the surface of the unheated ton bag, so as to blow and clean the surface of the ton bag, ensure the cleanliness of the surface of the ton bag, and improve its cutting quality; and the airflow in the recoil pipe 73 will move from top to bottom along the surface of the dust filter plate 561, so as to blow the powder attached and accumulated on the dust filter plate 561 to the bottom of the filter box 56, thereby improving the filtering effect of the dust filter plate 561. Then, when the lifting plate 5 is reset upward, the limit plate 8 will be separated from the contact switch 82, and the electromagnetic valves in the exhaust pipe 71 and the recoil pipe 73 will be closed. Example

[0035] Reference Figure 1-Figure 8 , which is basically the same as the first embodiment. On the basis of the first embodiment, a slitting method for producing ton bags is proposed, and the steps are as follows: Step 1: The ton bag wrapped on the feeding roller 22 passes through the guide roller 2 and the fixed material rack 21 in sequence; Step 2: Pull the ton bag forward intermittently and heat it; Step 3: Cut the ton bag in the gap between its movements; Step 4: Clean the cutting part after each cutting is completed.

[0036] Reference Figure 1-Figure 8In the present invention, when in use, the ton bag wrapped on the feeding roller 22 is passed through the guide roller 2 and the feeding roller 32 in sequence, and then the servo motor 34 is turned on. Under the transmission action of the pulley group 33, the guide roller 2 and the feeding roller 32 are driven to rotate, thereby pushing the ton bag to move along the surface of the processing table 1. When the ton bag moves forward a slitting distance, the servo motor 34 stops rotating. At this time, the telescopic end of the electric push rod 31 extends downward, so that the lifting plate 5 moves toward the surface of the processing table 1 with the cutting knife 52. Finally, when the cutting knife 52 reaches the surface of the processing table 1, the single slitting of the ton bag is completed, and then the above process is repeated continuously to realize the whole roll. The continuous slitting of the ton bags effectively improves the slitting efficiency; and in the process of the ton bags moving forward, they will fit against the bottom of the softening box 4, and the heat generated by the heating tube 41 in the softening box 4 will appropriately preheat the ton bags passing through the bottom of the softening box 4, so that the ton bags are softened, reducing their brittleness, facilitating subsequent cutting and reducing the generation of edge burrs, thereby improving the slitting quality of the ton bags; at the same time, after the ton bags are softened, under the rolling action of the feed roller 32, the ton bags can be flattened before slitting, ensuring that the surface of the ton bag material is flat and wrinkle-free, avoiding unevenness or deviation during the cutting process, and further improving the slitting quality.

[0037] When the lifting plate 5 is pushed downward, the piston plate 531 is pushed toward the bottom of the piston chamber 53 through the push-pull rod 532, thereby compressing the gas in the inner cavity of the piston chamber 53 and opening the one-way valve in the inflation pipe 63, so that the compressed gas enters the guide chamber 6 along the inflation pipe 63, thereby increasing the air pressure in the guide chamber 6, and then pushing the air pressure plate 61 downward, thereby pushing the heated gas in the guide chamber 6 to pass through the heating pipe 41 and quickly approach the surface of the ton bag. Since the distance between the bottom center of the softening box 4 and the cutting knife 52 is equal to the length of the ton bag required to be cut each time, the downward moving heat flow will just quickly contact the cutting area of ​​the ton bag, thereby quickly heating the cutting area, ensuring that the cutting area is effectively softened, and improving the subsequent cutting quality. When the lifting plate 5 moves to the bottom, the limit plate 8 will contact the contact switch 82, thereby opening the solenoid valves in the exhaust pipe 71 and the recoil pipe 73. At this time, the gas in the guide chamber 6 will be discharged along the exhaust pipe 71 and the recoil pipe 73, and the airflow in the exhaust pipe 71 will blow along the exhaust box 7 and the blowing hole 72 to the unheated surface of the ton bag, so as to blow and clean the surface of the ton bag, ensure the cleanliness of the surface of the ton bag, and improve its cutting quality; and the airflow in the recoil pipe 73 will move from top to bottom along the surface of the dust filter plate 561, so as to blow the powder attached and accumulated on the dust filter plate 561 to the bottom of the filter box 56, thereby improving the filtering effect of the dust filter plate 561. Subsequently, when the lifting plate 5 is in the process of upward reset, the limit plate 8 will disengage from the contact switch 82. At this time, the solenoid valves in the exhaust pipe 71 and the recoil pipe 73 will be closed, and then the push-pull rod 532 will pull the piston plate 531 upward, thereby generating suction in the piston chamber 53 and opening the one-way valve in the suction pipe 54, so that the suction is transmitted along the suction pipe 54 and the inner cavity of the lifting plate 5 to the dust suction hole 55, thereby generating suction on both sides of the cutting knife 52, thereby absorbing the cutting powder attached to the cutting knife 52 and the residual on the processing table 1, and finally being trapped in the filter box 56 under the filtering action of the dust filter plate 561, thereby effectively improving the cleanliness of the cutting area and the surface of the cutting knife 52, thereby ensuring the slitting accuracy and improving the slitting quality.
