Referring to fig. 1 to 8, a high efficiency processing apparatus for degradable plastic bags includes a printing cylinder 1, wherein two fan-shaped printing parts 2 symmetrical about an axis are provided on the printing cylinder 1, and further includes:
the printing cylinder 1 is arranged at the top of the bracket body;
the main traction mechanism is arranged at the front end of the bracket body and is used for forward traction and conveying of the double-layer plastic bag raw material 27;
the damping traction mechanism is arranged at the rear end of the bracket body and is used for drawing and straightening the double-layer plastic bag raw material 27 backwards; by applying a backward reverse resistance during the forward traction of the plastic bag by the main traction mechanism, the plastic bag raw material 27 is flattened so that the printing cylinder 1 can smoothly perform reliable printing on the upper plastic bag.
The middle section bottom of support body is equipped with the supporting platform 3 that carries out vertical support when fan-shaped printing portion 2 carries out the printing to upper plastic bag. The support platform 3 is used for providing upward supporting force for the lower plastic bag so that the printing cylinder 1 can smoothly print the pattern made of quick-drying material on the surface of the upper plastic bag.
The support body is by two side support plates 4 and a plurality of connecting rod 5 that are used for fixed connection two side support plates 4, and the both ends of supporting platform 3 are respectively with the bottom fixed connection of two side support plates 4, and printing cylinder 1 is located between two side support plates 4. The plastic bag raw material 27 cut to form two layers firstly passes through the damping traction mechanism, passes between the printing cylinder 1 and the supporting platform 3, and finally passes through the main traction mechanism, so that a traction conveying route is formed.
The main traction mechanism comprises two horizontal roll shafts 6 which are arranged at intervals up and down, and two first stepping motors 7 which are respectively used for driving the two horizontal roll shafts 6 to rotate in opposite directions, the front ends of double-layer plastic bag raw materials 27 penetrate through the space between the two horizontal roll shafts 6 which are parallel and clung to each other, and the end parts of the two horizontal roll shafts 6 are respectively provided with a first tensioning mechanism used for pulling the two horizontal roll shafts towards each other. The two horizontal roll shafts 6 are driven to rotate in opposite directions by the two first stepping motors 7, so that the two horizontal roll shafts 6 can respectively pull and convey the upper layer of plastic bag raw materials 27 and the lower layer of plastic bag raw materials forwards. The first tensioning mechanism is used for ensuring that the two horizontal roll shafts 6 can be mutually abutted, so that enough friction force is generated between the horizontal roll shafts 6 and the surface of the plastic bag raw material 27.
The damping traction mechanism comprises two hysteresis roll shafts 8 which are arranged at an upper and lower interval and two second stepping motors 9 which are respectively used for driving the two hysteresis roll shafts 8 to rotate in opposite directions, the front ends of double-layer plastic bag raw materials 27 sequentially penetrate through the two parallel hysteresis roll shafts 8 which are tightly adhered to each other and then penetrate out from between the two horizontal roll shafts 6, and the end parts of the two hysteresis roll shafts 8 are respectively provided with a second tensioning mechanism used for pulling the two hysteresis roll shafts in opposite directions. The two second hysteresis roll shafts 8 are driven to rotate in opposite directions by the two second stepping motors 9, so that backward reverse hysteresis resistance is respectively generated on the upper layer of plastic bag raw materials 27 and the lower layer of plastic bag raw materials 27, and the effect of flattening the two layers of plastic bag raw materials 27 is achieved by matching with traction force. The second tensioning mechanism is used for ensuring that the two hysteresis roll shafts 8 can be tightly attached to the surfaces of the two layers of plastic bags.
Each hysteresis roll shaft 8 consists of an inner shaft 10 connected with the second stepping motor 9, a first magnetic tube sleeve 11 fixedly sleeved on the outer side of the inner shaft 10 and a second magnetic tube sleeve 12 movably sleeved on the outer side of the first magnetic tube sleeve 11. As shown in fig. 5, the upper inner shaft 10 drives the first magnetic tube sleeve 11 to rotate clockwise, at this time, the second magnetic tube sleeve 12 should rotate clockwise along with the first magnetic tube sleeve 11 due to the hysteresis force, but the second magnetic tube sleeve 12 contacts with the upper plastic bag raw material 27 and generates a reverse friction force, so that the second magnetic tube is forced to rotate counterclockwise against the hysteresis force along with the forward movement of the upper plastic bag raw material 27, and the hysteresis force is always present between the first magnetic tube sleeve 11 and the second magnetic tube sleeve 12, so that the second magnetic tube sleeve 12 always has a clockwise rotation trend along with the clockwise rotation of the first magnetic tube sleeve 11, and the clockwise rotation trend is precisely that the second magnetic tube sleeve 12 can apply a backward reverse friction force to the upper plastic bag raw material 27 contacted with the second magnetic tube sleeve, so that the upper plastic bag raw material 27 is flattened backward, and the flattening process of the lower plastic bag is the same.
