Description

Technical Field

[0001] The utility model relates to the technical field of plastic foam processing, and specifically relates to a plastic foam wire cutting machine. Background Technique

[0002] Plastic foam, which is a chemical material, full name polystyrene plastic, is a thermoplastic material. Each cubic meter contains 3 million to 6 million independent closed air bubbles, and the volume of air contained is more than 98%. Since the thermal conductivity of air is very small and is enclosed in the foam plastic and cannot convect, EPS is a material with very excellent heat insulation and heat preservation performance.

[0003] When processing existing plastic foam, it is necessary to cut it into the required shape for subsequent use. Most of the existing cutting methods use wire cutting, which can evenly cut thicker plastic foam.

[0004] For the above technical conditions, there are still defects: when cutting the plastic foam with a wire, it cannot tightly hold the plastic foam well, thus reducing the cutting effect.

[0005] Based on this, the utility model designs a plastic foam wire cutting machine to solve the above problems. Content of the Utility Model

[0006] The purpose of the utility model is to provide a plastic foam wire cutting machine to solve the above technical problems.

[0007] To achieve the above purpose, the utility model provides the following technical solution: a plastic foam wire cutting machine, including a cutting table. A support is fixedly connected to the middle position of the top of the cutting table. An upper guide wheel is rotatably connected to one side of the support. A cutting wire is arranged on the upper guide wheel. A driving device for driving the cutting wire is arranged on the cutting table. A positioning frame is arranged at the bottom of the cutting table. A lower guide wheel is rotatably connected to the positioning frame. One side of the cutting wire contacts the lower guide wheel and thus changes the direction. A hydraulic telescopic rod is fixedly connected to the inner top of the support. The bottom end of the hydraulic telescopic rod is fixedly connected to a driving frame. The bottom end of the driving frame is fixedly connected to a pressing rod. The pressing rod presses against the plastic foam to be cut during use.

[0008] By adopting the above technical solution, the plastic foam to be cut can be tightly clamped, thereby improving the subsequent cutting effect.

[0009] Preferably, a support column is fixedly connected to the inside of the support. One end of the support column is fixedly connected to a positioning sleeve. The cutting wire passes through the positioning sleeve.

[0010] By adopting the above technical solution, the cutting wire can maintain its position during cutting, making its wire routing more stable.

[0011] Preferably, the driving device includes an outer frame and a driving motor fixedly connected inside the outer frame. A rotating wheel is fixedly connected to the output shaft of the driving motor. One end of the cutting wire is wound forward around the left wheel, and the other end of the cutting wire is wound backward around the right wheel.

[0012] By adopting the above technical solution, a single driving motor can simultaneously control the coiling and loosening of the cutting wire, and continuous cutting can be achieved by simply adjusting the rotation direction of the driving motor.

[0013] Preferably, a tensioning mechanism for tensioning the cutting wire is further provided inside the outer frame.

[0014] By adopting the above technical solution, the cutting wire can be tensioned to achieve a better cutting effect.

[0015] Preferably, four groups of columns for support are fixedly connected to the bottom of the cutting table.

[0016] By adopting the above technical solution, the height of the cutting table is increased to enhance the usage effect.

[0017] In summary, the present application has the following beneficial technical effects: By providing the hydraulic telescopic rod and the abutting rod, the plastic foam to be cut can be well abutted, facilitating subsequent cutting. Then, by providing the rotating wheel and the driving motor, continuous wire cutting can be performed by simply changing the rotation direction of the output shaft of the driving motor, enhancing the usage effect of the cutting device.

[0026] The following is a further detailed description of this application in conjunction with the attached Figures 1-4 drawings.

[0027] Refer to Figure 1 and Figure 2 , a plastic foam wire cutting machine, including a cutting table 1, four groups of columns 2 for support are fixedly connected to the bottom of the cutting table 1, a bracket 3 is fixedly connected to the middle position of the top of the cutting table 1, an upper guide wheel 4 is rotatably connected to one side of the bracket 3, a cutting wire 5 is arranged on the upper guide wheel 4, and at the same time, a driving device 8 for driving the cutting wire 5 is arranged on the cutting table 1 to change the traveling direction of the cutting wire 5. A positioning frame 6 is arranged at the bottom of the cutting table 1, a lower guide wheel 7 is rotatably connected to the positioning frame 6, and one side of the cutting wire 5 contacts the lower guide wheel 7 and changes the direction therefrom. A hydraulic telescopic rod 9 is fixedly connected to the inner top of the bracket 3, a driving frame 10 is fixedly connected to the bottom end of the hydraulic telescopic rod 9, which can control the up and down movement of the driving frame 10, and a tightening rod 11 is fixedly connected to the bottom end of the driving frame 10. The tightening rod 11 abuts against the plastic foam to be cut during use.

[0028] Further, refer to Figure 1 , a support column 12 is fixedly connected to the inside of the bracket 3, a positioning sleeve 13 is fixedly connected to one end of the support column 12, and the cutting wire 5 passes through the positioning sleeve 13.

[0029] Further, refer to Figure 3 and Figure 4, the driving device 8 includes an outer frame and a driving motor (not shown in the figure) fixedly connected inside the outer frame. A rotating wheel 14 is fixedly connected to the output shaft of the driving motor. One end of the cutting wire 5 is wound forward around the left wheel 14A, and the other end of the cutting wire 5 is wound backward around the right wheel 14B. When the rotating wheel 14 is controlled to rotate by the driving motor, one end of the cutting wire is coiled and the other end is loosened, realizing rapid movement, and then the foam is cut. After moving completely once, the driving motor is controlled to reverse, so as to perform the next wire feeding and cutting.

[0030] Furthermore, referring to Figure 3 , a tensioning mechanism 15 for tensioning the cutting wire 5 is further provided inside the outer frame.

[0031] The implementation principle of this embodiment is as follows: When in use, place the plastic foam to be cut on the cutting table 1, then start the driving motor, control the rotating wheel 14 to rotate through the driving motor, so that the cutting wire 5 moves at a high speed, and then cut the plastic foam. After one rotation process, control the driving motor to reverse, so that the cutting wire 5 moves in the reverse direction and perform another cut. By continuously changing the traveling direction of the cutting wire 5, continuous cutting is achieved. At the same time, during the cutting process, start the hydraulic telescopic rod 9, so that the telescopic end of the hydraulic telescopic rod 9 extends, and the foam plastic is tightened through the pressing rod 11, so as to facilitate subsequent cutting.
