Description

Technical Field

[0001] The utility model relates to a machine, in particular to a cutting machine for cutting PVC pine strips of Christmas trees. Background Art

[0002] When cutting V-leaf with traditional cleaning rod, the upper blade is often replaced with a special blade with a width of only two to three millimeters, the leaf is pulled out by hand, and then the length is determined by the mold, and it is cut from top to bottom. In this way, only the iron wire can be cut, and the leather material cannot be cut. However, because the PVC leaves are divergent in all directions, the knife distributed 360 degrees around the garden will cut the leaves if it is too wide, and sometimes the knife cannot cut the iron wire if it is too narrow, and it will slip off. In addition, the pulled PVC loose strips are mainly divided into two types: PVC stamped leaves that are stamped into sections and connected by iron wires, and unstamped cleaning rods. Stamped leaves require accurate cutting from the stamping position, not too much or too little, otherwise the leaves will be useless, and the PVC leaves of the cleaning rod are generally cut into two types, one is the false garden leaf, and the other is the V leaf. The stamped PVC pine strips were originally punched into sections by hand with a small electric punch. The location of the cut position in the middle was completely determined by human observation and hand movement to determine the cutting position. The traditional method of cutting fake garden leaves with a cleaning rod is to pull out the leaves from the hole of a large garden hole bottom knife from multiple leaves by hand, and then cut them off by positioning the length size through the mold. However, this method has the problems of low efficiency, inaccurate size, and irregular and unround cut leaves. In this way, the purpose of cutting the wire but not the leather is achieved. However, because the PVC leaves are divergent in all directions, the knife distributed 360 degrees around the garden will cut off some of the leaves if it is too wide; if the knife is too narrow, sometimes it will not cut the wire and slip off. No matter how wide the knife is, it will cut the leaves to some extent, but the cut leaves are a bit broken and not perfect.

[0003] As a result, patented technologies with technological innovations have emerged, such as Chinese Patent No. 202010916784.8, entitled "An automatic cutting mechanism for simulated Christmas tree leaves", which discloses an automatic cutting mechanism for simulated Christmas tree leaves, including a frame on which a leaf storage rack, a leaf taking assembly, a cutting assembly, a finished product grabbing device and a leaf collecting device are respectively fixed, and a leaf pocket and a tail material box are also fixed on the frame, which has a complex structure and inconvenient maintenance. Another example is patent No. 202211370937.9, entitled "A cutting and shaping device for simulated pine needles", which discloses a cutting and shaping device for simulated pine needles, including a conveying mechanism, a cutting mechanism, a shaping mechanism and a discharging mechanism arranged in sequence, the shaping mechanism including a turntable assembly, a pine needle shaping cylinder being provided on the turntable assembly, and an electromagnetic heating assembly being provided on the pine needle shaping cylinder. The conveying mechanism sends the simulated pine needle strips into the cutting mechanism for cutting, and then enters the shaping mechanism, where they are shaped under the heating of the electromagnetic heating assembly, and then discharged from the discharging mechanism. However, the technical problem of cutting leaves without damaging the leaves is still not achieved.

[0004] Based on the defects of the above-mentioned technology, it leads to completely relying on human eyes and hands for positioning, which is inefficient, inaccurate positioning due to human fatigue, and dangerous manual operation. Therefore, it is necessary to innovate and develop a leaf cutting machine that can set the leaf cutting mode with the machine interface and switch the leaf cutting gear with a manual button to achieve safety and efficiency, produce very beautiful Christmas tree pine strips, and carry out large-scale industrial production, reduce waste for production enterprises, improve yield rate, save production costs, and solve the technical problem of low yield rate. Summary of the invention

[0005] The purpose of the utility model is to innovate and develop a cutting machine for PVC Christmas tree pine strips, which can cut pine strips without damaging the leaf fibers and improve product quality. After the machine automatically cuts, the strips are neatly stacked. The worker only needs to collect the cut materials from the receiving hopper and frame them to complete the work. The machine should also be equipped with a selection switch for the three modes of stamping leaves, V leaves and fake garden heads, which can be switched manually or automatically, with automatic optical fiber recognition and precise positioning. It is equipped with a small soft hole cutter and a material pressing and feeding device to allow the material to shrink and deform in the hole. With different working modes of pressing and feeding, and different running trajectories, all leaf shapes can be cut without changing the cutter.

[0006] A Christmas tree PVC pine strip cutting machine is implemented, including a motor control mechanism, a cutting mechanism, a clamping mechanism, a feeding hopper and a material receiving conveyor belt arranged on a main body frame, wherein the cutting mechanism includes an optical fiber identification component, a material guide component, a material pressing component, a hanger, a cutter component, a switch button and a clamping component.

[0007] The optical fiber identification component is provided with an optical fiber amplifier, an optical fiber transmitter and an optical fiber receiver; the optical fiber amplifier is arranged on the frame plate and is electrically connected to the motor control mechanism, and the optical fiber transmitter and the optical fiber receiver are electrically connected by the optical fiber amplifier.

[0008] The cutter assembly of the cutting mechanism includes a surface knife holder connected to a bottom knife seat, a bottom knife, a notch gasket, a knife holder pressure plate, a surface knife, a small square knife, a gasket, a surface knife back plate, and screws are tightened in time to form a cutter; the bottom knife seat is fixed to the table with screws, and two notch gaskets and two knife holder pressure plates are respectively pressed on both sides of the bottom knife and the bottom knife seat by locking screws, so that two sliding grooves of fixed size are formed between the bottom knife and the knife holder pressure plate, and are connected to the bottom knife seat to form a bottom knife assembly.

[0009] After the face knife is fixedly positioned and buckled with the small square knife, it is locked with the gasket and the corresponding screw holes of the face knife back plate to form a fastened face knife and is inserted into the bottom knife sliding groove to form a cutting knife.

[0010] The face knife of the cutting knife assembly is provided with step grooves on both sides, and the step grooves are L-shaped grooves; the face knife is also provided with a fixing position for clamping a small square knife, and screw holes are provided on each side of the fixing position, and screw holes for reinforcing buckles are also provided at the lower end of the small square knife fixing position. The small square knife hole is connected to the conical nut corresponding to the gasket and the back plate of the face knife and locked with screws to form a sturdy and sharp cutter.

[0011] The small square knife is provided with a V-shaped groove on the edge and a conical nut hole in the middle.

[0012] The pine branch cutting enters the material pressing trumpet mouth from the material guiding trumpet mouth entrance, and passes through the gap center hole formed by the optical fiber transmitter and the optical fiber receiver arranged on the optical fiber seat, after passing through the material penetration hole of the bottom knife seat and the stacked bottom knife, the pine strips are clamped by the chuck through the blade groove after the surface knife and the small square knife are stacked, completing the continuous action of the assembly line operation.

[0013] The optical fiber identification is provided with a small circular hole on the optical fiber seat, and an optical fiber transmitter and an optical fiber receiver are provided at the corresponding position of the small circular hole. When the loose strip is inserted into the small circular hole, the red light emitted by the optical fiber transmitter will change the pulse mutation signal of the loose strip from nothing to something, the traveling crane will move forward to its position, and then the chuck will clamp the loose strip and extend it from the small circular hole and pull it backward. In the process of the loose strip moving backward with the traveling crane, light leakage occurs at the position where there is a stamping notch and is detected by the optical fiber sensing switch. The optical fiber amplifier will output an interrupt signal to the control system, and the control system will perform an interrupt positioning according to the prompt of the interrupt signal, and then control the cutter to cut the loose strip at the accurate position and stop automatically, and the operation will be repeated until the production operation is completed.

[0014] The operation panel of the cutting mechanism is provided with a plurality of switchable menu items for adjusting the operation requirements required for the parameters of cutting the loose strips.

[0015] When setting the parameters for cutting the loose strips, the cutting mechanism can be set on the operation panel or by manual buttons, thereby achieving the function of an intelligent cutting machine that can be used by both humans and machines.

[0016] The cutting mechanism is provided with more than two sets of cutting knives and clamping heads which work independently on the table plate of the frame.

[0017] Beneficial Effects

[0018] The beneficial technical effect of the utility model is that the spacing between the bottom knife and the pressure plate is pressed by the pad to form a fixed guide slideway, which is easy to install and does not require adjustment. The traditional face knife is transformed into a face knife holder, which forms a sliding fit in the double guide grooves formed after the bottom knife and the pressure plate are assembled, and the small square knife is inserted into the face knife holder together with the face knife back plate. The contact and fit relationship between the blade surface of the small square knife and the bottom knife is stabilized by adjusting the tightening screw and the top tightening screw to form a stable shearing structure.

[0019] Secondly, the optical fiber can automatically identify and accurately position with an accuracy of 0.1mm, and can cut out all leaf shapes without changing the tool, achieving a one-machine-universal technical effect.

[0020] Thirdly, the machine of the utility model has three leaf cutting switch gear switching modes, namely, stamping leaf, false round head and V leaf, which can be set in the operation panel or switched by button, which is very convenient for automatic or manual operation. The number of leaves cut and the size positioning can be set as needed to ensure that only iron wire can be cut and leaf silk will not be cut.

[0021] Finally, it reduces waste for manufacturing companies, improves the yield rate, saves production costs for companies, and solves the technical difficulties that previously resulted from low yield rates. BRIEF DESCRIPTION OF THE DRAWINGS
