Slitting mechanism for plastic packaging products

Technical Field

The utility model belongs to the technical field of plastic packaging goods apparatus, especially, relate to a cutting mechanism of plastic packaging goods.

Background

The current plastic packaging products, such as plastic ice cream boxes, are generally manufactured by first manufacturing a mold and then manufacturing the mold into a row of packaging products. Such packaging products are all large continuous plastic sheets formed by regularly arranging the oil from one packaging product to another in consideration of manufacturing efficiency and convenience. Then the whole plastic plate is cut into a plastic plate with a smaller specification, and finally the plastic plate with the smaller specification is punched into an individual packaging product. At present, large continuous plastic plates are cut into small-sized plastic plates by hand. The cutting defects are low in efficiency, and manual cutting by a blade is hesitant to be adopted during cutting, so that the specifications of each small-sized plastic plate are inconsistent, and the subsequent transportation and punching are adversely affected.

The limiting rod is used for limiting the position of the plastic plate entering the frame plate. The feeding device has the advantages that the feeding position of the plastic plate is well controlled, so that the plastic plate is positioned in the cutting range of the cutter in the feeding process, and the condition that the plastic plate is not completely cut is avoided.

Preferably, the top end surface of the frame plate is an inclined surface, and the bottom end surface of the sliding plate is an inclined surface which is matched with the top end surface of the frame plate in an attaching mode.

The effect that the top end face of frame plate and the bottom end face of slide be the inclined plane is the downward slope of formation, and its effect is that the small-specification plastic slab that forms after being convenient for cut can slide along the slope automatically in the collection device.

The utility model has the advantages that: the automatic mechanical slitting is adopted, the slitting efficiency is obviously improved, the specifications of small-specification plastic plates formed by slitting are basically kept consistent, and uniform collection, transportation and subsequent processing are facilitated.

Detailed Description

The following embodiments are specifically described with reference to fig. 1 to 3:

as shown in fig. 2, the sliding plate 1 is generally made of a metal plate, the sliding plate is a strip-shaped plate as a whole, the left side and the right side of the sliding plate are connected with the rollers, the side surface of the bottom of the sliding plate is an inclined surface, the inclined surface is provided with a strip-shaped groove 2 along the length direction of the sliding plate, and the depth of the strip-shaped groove is generally 1-2 cm.

As shown in fig. 3, the shelf plate 3 is generally made of a metal plate, and the entirety of the shelf plate is also an elongated plate. The upper end face of the frame plate is an inclined plane, and a cutting hole 4 penetrating through the whole frame plate is formed in the length direction of the eye frame plate on the inclined plane. The length of the cutting hole is consistent with that of the elongated groove.

As shown in fig. 1, the frame 5 is a quadrangular frame. The rollers at the two ends of the sliding plate are arranged in the sliding grooves 6 at the left side and the right side of the frame. The upper part of the frame is fixedly provided with a sliding plate cylinder 7, and the output end of the sliding plate cylinder is connected with the middle part of the sliding plate in the length direction. The sliding plate can do lifting motion on the frame along the sliding groove along with the sliding plate cylinder.

The middle lower part of the frame is fixedly welded with a frame plate. The both ends welding of frame plate is in the frame, and the frame plate is located the slide under the department. When the slide plate descends, the bottom end face of the slide plate is tightly attached to the upper end face of the frame plate. At the moment, the cutting hole is communicated with the elongated groove. The tip department of frame plate is provided with 2 gag lever posts 15, and the spacing scope of gag lever post does not surpass cuts the scope.

The lower part department fixed welding of frame has 2 guide bars 8, and the guide bar is cylindrical. The 2 guide rods are distributed up and down, and the 2 guide rods are positioned right below the cutting hole. The 2 guide rods are sleeved with a guide seat 9 in a sliding mode, and the guide seat is a circular metal block. The upper end surface of the guide seat is fixedly clamped with a cutter 10. One end of the cutter penetrates through the cutting hole from bottom to top and then extends into the strip-shaped groove.

The lower side of the frame is provided with a stroke mechanism, wherein a guide arm 11 is connected at the side of the guide seat. One end of the stroke rod 12 is hinged with the guide arm, and the other end of the stroke rod is hinged with the lower side of the frame. The guide cylinder 13 is fixed at the lower side of the frame, the output of which is connected to the guide arm. The stroke rod, the guide arm and the guide cylinder are positioned on the same plane. The guide rod, the guide arm and the stroke rod are distributed in a zigzag shape. The output distance of the guide cylinder is fixed, so that the stroke distance of the guide seat on the guide rod can be controlled by controlling the connecting position of the output end of the guide cylinder on the guide arm, namely the slitting stroke distance of the cutter can be controlled.

The frame is provided with a timer at the end of the frame plate, the timer is connected with the controller, and the guide cylinder and the sliding plate cylinder are also connected with the controller. Because the feeding of the plastic plate is uniform, and the cutting time is also fixed, when the plastic plate is generally cut into small-specification plastic plates, the time can be set as a timing parameter only after the time from feeding to cutting one small-specification plastic plate is calculated in advance. The cutting can be carried out in an orderly and cyclic manner through the coordination of the controller, and the consistency of the cutting specification is ensured.

When the plastic board is cut, the plastic board enters the frame board at a constant speed, and after the timer counts the time, the sliding board descends to the frame board under the push of the sliding board cylinder, so that the plastic board is clamped by the sliding board and the frame board. (the plastic plate is now out of feed) at this point, the pilot cylinder is activated. The guide arm and the stroke rod are driven to swing, so that the guide seat is driven to slide on the guide rod. The cutter begins to cut the plastic sheet. After the cutting is finished, the sliding plate rises, and the cut small-size plastic plate can slide downwards to the collecting box along the inclined surface.
