[0002] A woven bag, also known as a snake skin bag, is a kind of plastic bag used for packaging. Its raw materials are generally various chemical plastic raw materials such as polyethylene and polypropylene.
[0003] After retrieving the patent document with the publication number of CN220409817U, this patent document discloses "a novel bag making machine for plastic woven bag production. After forming a split structure between the convex seat protruding inside the fixed frame and the rotating shaft, the rotating shaft can be directly taken out to install the material bundle. Then, when assembling, directly rotate the spiral ring sleeve to drive the convex block to engage inside the convex seat, and the operation is simple. When installing and replacing the material bundle, the rotating shaft can be directly taken out for operation."
[0004] However, after using up a bundle of materials in the above device, the operator needs to perform a series of operations to remove the used materials, and then install a new material bundle on the device so that the device can continue the subsequent production operation. This will cause the device to pause, resulting in a certain period of stagnation in production and easily affecting the production efficiency of the bag making machine. Content of the Utility Model
[0005] The purpose of the utility model is to provide a bag making machine for plastic woven bag production to solve the above problems.
[0006] The utility model realizes the above purpose through the following technical solutions:
[0007] A bag making machine for plastic woven bag production includes a stepped platform frame. A bag making machine body for producing woven bags from materials is installed at the upper end of the stepped platform frame. It also includes a feeding mechanism for replacing the used materials.
[0008] The feeding mechanism includes an upper extension plate fixed at the upper end of the lower plane of the stepped platform frame. A motor is installed at the rear end of the upper extension plate. A rotating shaft is fixed at the output end of the motor. A triangular frame is fixed around the rotating shaft. Loading rods are fixed at the three corners of the triangular frame. A material roll is installed on the loading rod close to the bag making machine body. An external extension electric push rod is installed at the lower end on one side of the upper extension plate. A first button is installed at one end of the external extension electric push rod, and the position of the first button corresponds to the lower loading rod. An external push plate is fixed at the telescopic end of the external extension electric push rod. A retraction electric push rod is installed at the upper end on one side of the upper extension plate. A second button is installed at one end of the retraction electric push rod, and the position of the second button corresponds to the upper loading rod. An inner push plate is fixed at the telescopic end of the retraction electric push rod. A cushioning frame is arranged in front of the rotating shaft, and the cushioning frame is fixed to the stepped platform frame. A placing frame is fixed at the upper end of the cushioning frame.
[0009] Preferably, the rear end of the loading rod protrudes from the rear end face of the tripod, and there is a spacing of 1 cm between the rear end of the loading rod and the upper extension plate.
[0010] Preferably, the front ends of the first button and the second button protrude from the front end face of the upper extension plate, and there is a spacing of 2 cm between the front end faces of the first button and the second button and the front end face of the upper extension plate.
[0011] Preferably, the rear end face of the loading rod and the front end faces of the first button and the second button are all rounded.
[0012] Preferably, the retractable lengths of the extending electric push rod and the retracting electric push rod correspond to the length of the loading rod.
[0013] Preferably, there is a spacing of 0.5 cm between the uppermost plane of the outer pushing plate and the lower end of the lower loading rod, and the lowermost plane of the inner pushing plate is 0.5 cm higher than the uppermost end of the storage rack.
[0014] The beneficial effects compared with the prior art are as follows:
[0015] Before the device operates, a new material roll needs to be placed on the storage rack. Subsequently, during operation, when the material on the loading rod close to the bag-making machine body runs out, the motor drives the tripod on the rotating shaft to rotate 120°, so that the rear end of the loading rod that has just run out of material presses against the first button, thereby starting the extending electric push rod. The extending electric push rod drives the outer pushing plate to discharge the material cylinder with the used-up material from this loading rod. At the same time, the loading rod originally at the first button will rotate to the second button and press the second button to start the retracting electric push rod, thereby pushing the new material roll on the storage rack into this loading rod for replacement when the currently used material roll runs out again. In this way, the time required for replacing the material can be reduced, thereby reducing the impact on production efficiency. Description of the Drawings

[0030] The loading mechanism includes an upper extension plate 3. The upper extension plate 3 is fixed to the upper end of the lower plane of the stepped frame 1. A motor 31 is installed at the rear end of the upper extension plate 3. A rotating shaft 32 is fixed to the output end of the motor 31. A triangular frame 33 is fixed around the rotating shaft 32. Loading rods 34 are fixed at the three corners of the triangular frame 33. The rear end of the loading rod 34 protrudes from the rear end face of the triangular frame 33, and there is a 1 cm gap between the rear end of the loading rod 34 and the upper extension plate 3. A material roll 35 is installed on the loading rod 34 close to the bag making machine body 2. An extended electric push rod 36 is installed at the lower end on one side of the upper extension plate 3. A first button 37 is installed at one end of the extended electric push rod 36, and the position of the first button 37 corresponds to the lower loading rod 34. The telescopic end of the extended electric push rod 36 is fixed with an outer push plate 38. There is a 0.5 cm gap between the uppermost plane of the outer push plate 38 and the lower end of the lower loading rod 34.
