Detailed ways

As shown in Figure 1-7, the multi-layer paper bag processing machine includes:

The frame 1 has a first layer of longitudinal guide rails 2 , a second layer of longitudinal guide rails 3 , a third layer of longitudinal guide rails 5 and a fourth layer of longitudinal guide rails 6 arranged at intervals from top to bottom.

The carton 8 for storing paper can be slid left and right along the second layer of longitudinal guide rails to achieve interchangeability between the first working position and the second working position. The first working position is on the left side of the second working position. Hang two longitudinal slats 13 side by side, the longitudinal slats and the bottom surface of the carton box have a longitudinal intersection line, the longitudinal slats can rotate around the longitudinal intersection line, and the lateral spacing of the two longitudinal slats is equal to the paper bag width.

The cardboard 4 that can swing up and down is located between the second layer of longitudinal guide rails and the third layer of longitudinal guide rails. The right end of the cardboard plate is hinged to the frame, and the gap between the right end of the cardboard plate and the bottom of the carton in the second working position is in the vertical direction. The height is equal to the wall thickness of the paper bag, the lateral width of the cardboard is slightly smaller than the width of the paper bag, and the cardboard is located directly below the area clamped by the two longitudinal slats of the carton in the second working position.

The suction paper tray 7 capable of providing negative pressure can slide left and right along the first layer of longitudinal guide rails to achieve interchange between the first working position and the second working position. One way to provide negative pressure is through the fan 11 arranged on the paper suction tray.

When the paper box and the suction tray are in the first working position, the suction tray works to suck up the paper, and the suction tray carrying the paper reaches the second working position and stops working. The first sheet of paper falls on the cardboard, and then the suction The paper tray moves to the left to the first working position, the suction paper tray works to pick up the second sheet of paper 18, and the glue roller 19 switches from the lower station to the upper station, and the second paper suction tray moves to the right in the process of absorbing the second sheet of paper. The two sheets of paper pass through the gluing roller at the upper station to complete the gluing on the lower surface of the second sheet of paper. If the paper bag wall consists of two sheets of paper, the side paper conveying process ends, if the paper bag wall consists of n sheets of paper, the side cycle performs the same work process as conveying the second paper until the nth sheet is conveyed, and the paper conveying process ends . Afterwards, the carton is moved to the second working position, and a stack of paper is pressed against the lower surface of the carton box at the second working position by the pendulum of the receiving board, and the two longitudinal slats rotate inwardly so that the paper forms a hem.

Then, the carton moves to the left, and the gluing device applies glue to the lower surface of the two folded edges during the leftward movement of the carton and the leftward movement of the folded paper driven by friction. The gluing device is two rubber rollers, which are respectively located at the two folding edges of the paper and are located outside the left end of the longitudinal slats.

Catch the convex mold 14 of the glued hemmed paper that falls when the carton carrying the glued hemmed paper arrives at the first working position, the convex mold has two horizontal top edges, the length of the horizontal top edge is at least equal to the width of the paper bag, and the convex mold It can slide left and right along the longitudinal guide rail of the fourth layer to realize interchange between the first working position and the second working position.

The die includes a V-shaped piece 16 in the middle and a left side hinged with the two transverse top edges of the V-shaped piece respectively. Plate 15 and right side plate 17, the profile line of the longitudinal section of the inner cavity of the die is in the middle of a small convex M shape, and the opening of the die is downward. When both the punch and the die are in the first working position, the The transverse top edges are respectively located directly below the two transverse top edges of the inner cavity of the die.

During the paper splicing process of the punch, the die is located at the second working position. After the paper splicing is completed, the die moves to the first working position, and the punch and die move relatively close to each other to fold the paper with glued hem into an M shape. , Then the punch and die are separated and the punch moves to the second working position, the left side plate and the right side plate of the die are squeezed in the middle, so that the corresponding folded edges of the paper are pressed and bonded together to form a paper bag.

The position change on the glue roller can be realized by common lifting device.

Considering the manufacturing process, the splicing board is a thin plate, and at least the two longitudinal sides of the splicing board are relatively thin. In order to make a stack of papers bond better, the two longitudinal sides of the cardboard are provided with multiple rows of upwardly protruding longitudinal ribs.

The up and down swing of the cardboard is realized by the cam 10 arranged under the left end of the cardboard. Of course, this mechanism for realizing the swing of the cardboard can also adopt other mechanisms such as hydraulic and pneumatic.

The inward rotation of the two longitudinal slats is achieved by corresponding to the two tapered rollers directly below the two longitudinal slats. The two rollers are respectively located on both sides of the left end of the cardboard and fixed on the cardboard. The two rollers have a horizontal shaft and the rollers The small end of the large end is closer to the cardboard, and the upper apex of the roller is slightly lower than the upper surface of the cardboard, so that when the paper is folded, the cardboard first pushes the paper into the area between the two longitudinal slats, and then the top of the roller Rotate the longitudinal slats inwards against the longitudinal slats. Of course, hydraulic, pneumatic and other mechanisms can also be used to realize.

In one way, the relative movement of the punch and the die to close contact is realized by the movement of the punch, and the punch is driven by the punch lifting mechanism. More specifically, the punch lifting mechanism is a winch respectively arranged on both sides of the punch.

The pressing of the left side plate and the right side plate of the die to the middle is realized by the side plate driving mechanism. The side plate driving mechanism includes two longitudinal moving blocks respectively arranged on the longitudinal sides of the die. The longitudinal guide rail on the mold moves, and the two longitudinal moving blocks are relatively close to push the left side plate and the right side plate to squeeze toward the middle. Of course, hydraulic, pneumatic and other mechanisms can also be used to realize.

In order to reduce friction, rollers directly in contact with the left side board or the right side board are arranged on the longitudinal moving block.

A locking and separating mechanism is set between the carton and the suction plate to lock the carton and the suction plate into one and separate, and the suction plate is provided with a moving drive for the paper box and the suction plate to provide power for the longitudinal movement of the paper suction plate mechanism. Therefore, only one driving mechanism is needed for the paper box and the paper suction plate, and the paper suction plate drives the paper box to move. Specifically, the carton moving drive mechanism is a rack and pinion mechanism.
