Description

Technical Field

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

[0002] At present, the production of PVC pine strips mainly uses the blade of the slats. When cutting V leaves, the upper blade is often replaced with a special blade with a width of only two to three millimeters, the leaves are pulled out by hand, and then the length size is positioned by the mold. Cut from top to bottom. 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 the wire cannot be cut and slips off. No matter how wide the knife is, it will cut the leaves to some extent, but the cut leaves are a little incomplete and not perfect.

[0003] When the existing bottom knife and surface knife for cutting PVC leaves cut the leaves, the leaves coming out from the material guide inlet to the cutting and feeding hole are misaligned with the cutter, so the leaves will be cut off together with the iron wire and the leaf wire when cutting, so the leaves are imperfect and the product quality is worrying. For example, Chinese Patent No. 202211370937.9, entitled "A Cutting and Shaping Device for Simulated Pine Needles", 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 includes a turntable assembly, a pine needle shaping cylinder is provided on the turntable assembly, and an electromagnetic heating assembly is provided on the pine needle shaping cylinder. The conveying mechanism sends the simulated pine needle pine strips into the cutting mechanism for cutting, and then enters the shaping mechanism, and is shaped under the heating of the electromagnetic heating assembly, and then discharged from the discharging mechanism, but still fails to achieve the technical problem of cutting leaves without damaging the leaves.

[0004] Based on the defects of the above-mentioned technology, it is necessary to innovate and develop a precise leaf cutting machine, which can set the leaf cutting mode by the machine interface and switch the leaf cutting gear by manual button, so as to achieve safety and efficiency, produce very beautiful Christmas tree pine strips, and solve the technical problem of low yield rate. Summary of the invention

[0005] The utility model aims to develop a cutter structure for PVC pine strips of Christmas trees, which can cut pine strips without damaging leaf fibers and improve product quality. The machine is also provided with a selection switch for three modes: punching leaves, V leaves and fake round heads, which can be switched manually or automatically.

[0006] A cutter structure for Christmas tree PVC pine strips is implemented, including a motor control mechanism, a cutter and a chuck arranged on a frame, characterized in that the cutter 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 and a surface knife back plate, and the screws are tightened in time to form the cutter.

[0007] The bottom knife seat is fixed on the table with screws, and two notch gaskets and two knife holder pressure plates are 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 with the bottom knife seat to form a bottom knife assembly.

[0008] 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.

[0009] The surface knife of the cutter is provided with step grooves on both sides, and the step grooves are L-shaped grooves; the surface 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 corresponding gasket and the surface knife back plate and locked with screws to form a sturdy and sharp cutter.

[0010] The small square knife is provided with a V-shaped groove on the edge and a conical nut hole in the middle.

[0011] Beneficial effects:

[0012] After the cutter of the utility model is installed and debugged once, there is no need to adjust the blade for a second time. The leaves can be cut accurately without damaging the leaves, and only the iron wire can be cut without cutting the leaf filaments. The maintenance is convenient, and the product quality and production efficiency are improved. BRIEF DESCRIPTION OF THE DRAWINGS

The material guide cylinder 322 is connected to the material guide bell mouth 325, and the V-leaf 503 is inserted into the inlet 3251 of the bell mouth 325 and enters the inlet 3351 of the pressure bell mouth 335, and continues to pass through the pressure bell mouth and insert it into the inlet 3151 of the material guide cylinder 315 of the hanger 34, and then passes through the blade groove 3555 formed by the small square knife 356 of the cutter 35 and the surface knife 355 and is clamped by the chuck 48 to form a leaf cutting channel of the assembly line.

[0058] The utility model can cut leaves accurately without damaging the leaves, has a simple structure, reduces manual operations, saves costs for production enterprises, and can provide intelligent production equipment replacement and upgrading for enterprises producing artificial Christmas trees, so that it can be promoted and used on a large scale in industrialization.

[0059] The above is only the technical solution of the present invention. Although the present invention has been described in detail through the above embodiments, those skilled in the art should understand that various modifications can be made in form and detail without departing from the scope defined by the claims of the present invention and also within the scope of protection.
