Description

Technical Field

[0001] The utility model relates to the technical field of roller-knife type plastic slitting, in particular to a roller-knife type plastic slitting and forming device. Background Art

[0002] Roller-type plastic slitting and forming devices are usually suitable for high-speed, precise cutting and forming of plastic films, sheets, etc., and are widely used in plastic packaging, printing, electronic products and other industries. The cutter is a tool used to separate the masterbatch from the individual. The cutters on the market can be roughly divided into two categories: one is a sheet cutter, which applies a force parallel to the back of the blade to the blade through rotation or other means, so that the blade completes the cutting and separation operation; the other type of roller cutter, which applies a force parallel to the blade stick by driving the blade to make a circular motion through the roller-like rotation, so that the blade is close to the cutting plate-like object to complete the slitting process, so that the masterbatch and the individual are separated.

[0003] The traditional slitting method is direct slitting. Most of the time, it is only used for cutting without other processing, which leads to a single processing method and cannot achieve multiple applications and combinations of cutters, raw materials, and products. The traditional slitting device only has a single cutting function and cannot perform additional processing, so the product has no more competitiveness.

[0004] To this end, we designed a roller-knife type plastic slitting and forming device, which can complete the cutting action while solidifying the relative position of the object and the main body in the product by semi-cutting, and achieve the concave printing pattern on the upper surface of the product, thereby improving the competitiveness of the product. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a roller knife type plastic slitting and forming device, which aims to improve the problem that the traditional slitting device has only a single cutting function and cannot perform additional processing actions.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a roller-knife type plastic slitting and forming device, comprising a base plate, one end surface of the base plate is fixedly connected to two fixed plates, one end surface of one of the fixed plates is fixedly connected to a servo motor, the output end of the servo motor is fixedly connected to a knife roller, the knife roller is a cylinder, one side outer wall of the knife roller is connected to a cutting knife through a plurality of first buckles, the edge of the cutting knife is provided with a plurality of blade grooves, and the outer wall of the knife roller is connected to a printing knife in the area surrounded by the cutting knife through a plurality of second buckles.

[0007] Preferably, the knife roller and the cutting knife are coaxial structures.

[0008] Preferably, one end surface of the bottom plate is fixedly connected to a cutting plate, the cutting plate is arranged below the guide roller, the cutting plate is provided with a cutting plate groove, and a plastic body is arranged on one end surface of the cutting plate.

[0009] Preferably, the plastic body is divided into a main body, a guest body and a connecting body after cutting.

[0010] Preferably, the cutting knife is divided into a blade groove and a blade portion without a groove, the blade portion without a groove is a flat area on the cutting knife, the edge of the blade portion without a groove is a blade edge, and the blade groove is a concave notch on the cutting blade surface.

[0011] Preferably, the printing knife is in close contact with one end surface of the plastic body, and the height of the printing knife is lower than the height of the cutting knife.

[0012] Preferably, the shape of the cutting plate groove is the shape of the contact area between the cutting knife driven by the rotation of the knife roller and the cutting plate.

[0013] Preferably, the cutting blade is divided into an axial blade and a circumferential blade.

[0014] The utility model has the following beneficial effects:

[0015] 1. In the utility model, by setting a printing knife, the appearance of the product can be optimized and the competitiveness of the product can be improved. Without affecting the production, the printing knife is a blade other than the main blade. The printing knife with a non-hollow pattern does not cut the product, so that the concave pattern on the surface of the product is a printed pattern. The printing knife with a hollow pattern makes dense dot cutting on the product. After the front and back of the product are transparent, the dense and transparent dot pattern of the product is used as a hollow pattern, thereby improving the competitiveness of the product, improving the optimization ability of the product appearance, and increasing the diversity of the product appearance.

[0016] 2. In the utility model, by setting a cutting plate groove, the shape of the cutting plate groove is determined by the point where the blade is tangent to the cutting plate when rotating, and the two are the same, so that the blade is extremely close to the cutting plate groove during rotation, and the blade does not contact the cutting plate groove. When the blade and the cutting plate groove are in a tangent state, the tip of the blade is in the space of the cutting plate groove but the two do not contact each other, and the cutting plate groove does not affect the rotation of the blade.

[0017] 3. In the present invention, the cutting knife and the printing knife can be replaced by setting the first buckle and the second buckle, thereby realizing the free installation and replacement of the cutting knife and the printing knife, and improving the competitiveness of the product.

[0024] The following will be combined with the drawings of the specification of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Reference Figure 1 , Figure 2 and Figure 4 The utility model provides an embodiment: a roller-knife type plastic slitting and forming device, including a bottom plate 8, one end surface of the bottom plate 8 is fixedly connected to two fixed plates 7, one end surface of a fixed plate 7 is fixedly connected to a servo motor 6, the output end of the servo motor 6 is fixedly connected to a knife roller 3, the knife roller 3 is a cylinder, the outer wall of the knife roller 3 is connected to a cutting knife 1 through a plurality of first buckles 11, a plurality of blade grooves 2 are distributed on the edge of the cutting knife 1, and a printing knife 9 is connected to the outer wall of the knife roller 3 through a plurality of second buckles 12 in the area surrounded by the cutting knife 1.

[0026] Specifically, the blade groove 2 and the cutting plate groove 5 are both concave inwardly sunken. The blade groove 2 can form intermittent virtual tangents between the object 16 and the main body 15 of the cut plastic body 10, so that the object 16 and the main body 15 are still connected, but can be easily removed or ejected later. By adding a printing knife 9, the printing knife 9 is the outline of various patterns and is located in the area surrounded by the cutting knife 1 on the guide roller 3. Patterns or hollows are cut out on the object 16, or a rubber body is used and ink is applied to print patterns on the main body 15. When the printing knife 9 is an incomplete slitting blade, the product can be added with cutting patterns of different shapes and types. When the printing knife 9 is a complete slitting blade, a hollow pattern is cut out on the main body 15 product, which reduces the loss of production materials during the production process, saves production costs, and increases the competitiveness of product appearance. The first buckle 11 and the second buckle 12 can allow the cutting knife 1 and the printing knife 9 to be replaced according to demand, so as to cut out main bodies 15 and patterns of different shapes.

[0027] The knife roller 3 and the cutting knife 1 are coaxial structures.

[0028] Specifically, the blade edge 13 of the cutting knife 1 is an arc-shaped area that is concentric with the knife roller 3 .

[0029] Reference Figure 1 One end surface of the bottom plate 8 is fixedly connected to the cutting plate 4, which is arranged below the knife roller 3. The cutting plate 4 is provided with a cutting plate groove 5. A plastic body 10 to be cut is arranged between the cutting plate 4 and the knife roller 3. The plastic body 10 is cut into a main body 15 and an object 16 by the cutting knife 1.

[0030] Specifically, when the cutting is realized, the plastic body 10 moves forward with the rotation of the knife roller 3, and the cutting knife 1 and the cutting plate 4 cooperate to complete the cutting of the main body 15 and the object 16 of the plastic body 10. While the cutting knife 1 applies force to the plastic body 10, the cutting plate 4 can provide a reverse supporting force, so that the cutting knife 1 completes the cutting of the product; when the cutting knife 1 completes the cutting of the plastic body 10, the cutting plate groove 5 prevents the cutting plate 4, which plays a supporting role, from colliding with the cutting knife 1.

[0031] Reference Figure 3 After cutting, the plastic body 10 is divided into a main body 15, a secondary body 16 and a connecting body 17.

[0032] Specifically, the blade groove 2 in the cutting knife 1 can leave a small amount of connectors 17 in the main body 15 and the outer body 16 of the product during cutting, so as to fix the main body 15 and the outer body 16 of the product.

[0033] Reference Figure 2The blade of the cutting knife 1 is divided into a blade groove 2 and a blade portion 14 without a groove. The blade portion 14 without a groove is a flat area on the cutting knife 1. The edge of the blade portion 14 without a groove is a blade edge 13. The blade groove 2 is a concave notch on the blade surface of the cutting knife 1.

[0034] Specifically, the blade portion 14 without groove is used for cutting by the blade edge 13. Preferably, the bottom of the blade groove 2 can also be provided with a blade edge 13 to cut the plastic body 10 to a certain thickness, reduce the thickness of the connector 17, and facilitate the subsequent separation of the main body 15 and the object 16.

[0035] Reference Figure 1 The printing knife 9 is close to one end surface of the plastic body 10, and the height of the printing knife 9 is lower than the height of the cutting knife 1.

[0036] Reference Figure 1 The shape of the cutting plate groove 5 is the shape of the contact area between the cutting knife 1 and the cutting plate 4 driven by the knife roller 3 when it rotates.

[0037] Specifically, the cutting plate groove 5 on the cutting plate 4 is a notch area on one side of the cutting plate 4 close to the knife roller 3 and matching with the contact point of the knife edge.

[0038] Reference Figure 1 and Figure 2 The cutting blade 1 is divided into an axial blade 19 and a circumferential blade 18 .

[0039] Specifically, the cutting blade 1 is divided into two types, one is a circumferential blade 18 along the circumference of the blade roller, and the other is an axial blade 19 in the axial direction. The axial blade 19 is divided into two types, one is the area surrounded by the circumferential blade 18 to cut out the main body 15, and the other is along the axial direction of the blade roller 3 from beginning to end, so as to segment the plastic body 10 and form a virtual tangent connection between two adjacent segments.

[0040] Working principle: the cutting knife 1 divides the plastic body 10 into segments, and divides the main body 15 and the object 16, and keeps them connected. The printing knife 9 can add printed cutting patterns to the plastic body 10 to improve the competitiveness of the product; the first buckle 11 and the second buckle 12 can realize the replacement of the printing knife 9 and the cutting knife 1 according to needs; when the cutting plate groove 5 completes the cutting of the product by the cutting knife 1, the supporting cutting plate 4 does not collide with the cutting knife 1, which can protect the blade edge 13.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
