[0024] like Figures 1 to 4As shown in the embodiment of this utility model, a square bottom bag making machine for easy feeding includes a workbench body 1; two symmetrically arranged fixed plates 11 are fixed to the top of the workbench body 1; a first motor 12 is fixed to the middle of the fixed plate 11; a rotating rod 13 is fixed to the output end of the first motor 12; a first hydraulic rod 14 is fixed to the middle of the rotating rod 13; a limit plate 15 is fixed to the output end of the first hydraulic rod 14; a second motor 16 is fixed to the side wall away from the fixed plate 11; a lead screw 18 is fixed to the output end of the second motor 16; a slider 17 is slidably connected to the middle of the lead screw 18; a second hydraulic rod 19 is fixed to the top of the slider 17; a connecting rod is fixed to the output end of the second hydraulic rod 19; a third hydraulic rod 110 is fixed to the bottom of the connecting rod; and the output end of the third hydraulic rod 110... A gripper 111 is fixedly connected. During operation, the gripper 111 is used to clamp the material roll, the first hydraulic rod 14 is activated, the distance between the two limiting plates 15 is adjusted, and then the second motor 16 is started. The output end of the second motor 16 drives the lead screw 18 to rotate, and the slider 17 drives the gripper 111 and the roll to slide towards the center of the limiting plate 15. After reaching the appropriate position, the third hydraulic rod 110 is activated, so that the roll is flush with and in contact with the center of the limiting plate 15. After the limiting plate 15 limits it, the first motor 12 is started, and the output end of the first motor 12 drives it to rotate, so that the unwinding operation can be carried out. Through the above structure, the combined use of the gripper 111 and the limiting plate 15 can complete the feeding operation quickly and stably, avoiding the problems of affecting work efficiency and safety caused by the need for manual feeding and unloading in traditional bag making machines.

[0025] like Figures 1 to 2 As shown, a telescopic rod 2 is fixedly connected to the middle of the workbench body 1 away from the limiting plate 15; an adjusting rod 21 is fixedly connected to the output end of the telescopic rod 2; two symmetrically arranged fixing blocks 22 are fixedly connected to the middle of the adjusting rod 21; a first spring 23 is fixedly connected to the bottom of the fixing block 22; a pressure plate 24 is fixedly connected to the end of the first spring 23; during operation, the adjusting rod 21 will change with the distance of the limiting plate 15 during the feeding process. After feeding is completed, the telescopic rod 2 can be activated to make the middle of the pressure plate 24 contact the surface of the roll material. At the same time, the elastic force of the first spring 23 can reduce the impact force generated when the pressure plate 24 contacts it. Through the above structure, the pressure plate 24 can not only effectively prevent the roll material from loosening during unwinding, but also avoid excessive pressure from scratching or damaging the surface of the roll material, thus affecting bag making operations.

[0026] like Figure 4As shown, a placement box 3 is fixedly connected to the middle of the workbench body 1 near the gripper 111; two sets of symmetrically arranged second springs 31 are fixedly connected to the middle of the placement box 3; a top plate 32 is fixedly connected to the top of the second springs 31; two sets of symmetrically arranged sliding rods 33 are fixedly connected to the middle of the placement box 3 near the second springs 31 and pass through the top plate 32; during operation, excess roll material is placed in the middle of the placement box 3 and in contact with the top plate 32. The elastic force of the second springs 31 can adjust the height of the top plate 32 according to the weight of the roll material, making it easy to pick up. Through the above structure, the combined use of the placement box 3 and the top plate 32 can not only provide protection for the roll material and prevent damage caused by careless dropping, but also increase the convenience of gripping by the gripper 111.

[0027] like Figure 2 As shown, two symmetrically arranged fourth hydraulic rods 4 are fixedly connected to the middle of the workbench body 1 near the fixed plate 11; the output end of the fourth hydraulic rod 4 is fixedly connected to a support plate 41; during operation, after the feeding operation is completed, the height of the support plate 41 can be adjusted by the fourth hydraulic rod 4 until the middle of the support plate 41 contacts the bottom of the coil. Through the above structure, the support plate 41 can provide support force for the coil, which helps to improve the accuracy and stability of the coil transmission or processing process and increase the service life of the device.

[0028] like Figure 1 As shown, two symmetrically arranged limiting rods 5 are slidably connected to the middle of the fixing block 22; the bottom of the limiting rods 5 is fixed to the pressure plate 24; during operation, the limiting rods 5 can limit the pressure plate 24 when it comes into contact with the coil, ensuring that the two maintain a suitable contact pressure and positional relationship. Through the above structure, it can effectively ensure that the pressure of the pressure plate 24 is evenly applied to the coil, and avoid the pressure plate 24 from tilting or shaking, which would damage the coil.

[0029] like Figure 2 As shown, multiple anti-slip pads 6 are fixedly connected to the middle of the limiting plate 15 in an equidistant manner; the anti-slip pads 6 are made of rubber; during operation, the rubber anti-slip pads 6 can increase the friction between the limiting plate 15 and the coiled material, preventing the coiled material from slipping and affecting the unwinding operation. Through the above structure, the coiled material can be effectively prevented from slipping in the middle of the limiting plate 15, ensuring that the limiting plate 15 can drive the coiled material to rotate and carry out a stable unwinding operation.

[0030] like Figure 3 As shown, two symmetrically arranged protective pads 7 are fixedly connected to the middle of the gripper 111. During operation, the protective pads 7 can provide protection for the gripper 111 when it comes into contact with the coiled material. Through the above structure, scratches and other problems caused by hard contact between the gripper 111 and the surface of the coiled material can be effectively avoided.

[0031] During operation, the material roll is gripped by the gripper 111, the first hydraulic rod 14 is activated, and the distance between the two limiting plates 15 is adjusted. Then, the second motor 16 is started, and the output end of the second motor 16 drives the lead screw 18 to rotate, causing the slider 17 to slide the gripper 111 and the material roll towards the center of the limiting plate 15. After reaching the appropriate position, the third hydraulic rod 110 is activated, making the material roll flush with and in contact with the center of the limiting plate 15. After the limiting plate 15 limits the material roll, the first motor 12 is started, and its output end rotates, allowing for unwinding. During unwinding, the adjusting rod 21 changes with the distance between the limiting plates 15. After unwinding is complete, the telescopic rod 2 can be activated, making the center of the pressure plate 24 contact the surface of the material roll. Meanwhile, the elastic force of the first spring 23 can reduce the impact force generated when the pressure plate 24 contacts it, placing the excess roll material in the middle of the placement box 3 and in contact with the top plate 32. The elastic force of the second spring 31 can adjust the height of the top plate 32 according to the weight of the roll material, making it easy to pick up. After the feeding operation is completed, the height of the support plate 41 can be adjusted by the fourth hydraulic rod 4 until the middle of the support plate 41 contacts the bottom of the roll material. The limiting rod 5 can limit the pressure plate 24 when it contacts the roll material, ensuring that the two maintain a suitable contact pressure and positional relationship. The rubber anti-slip pad 6 can increase the friction between the limiting plate 15 and the roll material, preventing the roll material from slipping and affecting the unwinding operation. The protective pad 7 can provide protection for the gripper 111 when it contacts the roll material.
