Description

Technical Field

[0001] The present application relates to the technical field of cutting devices, and in particular to a foam plastic cutting device. Background Art

[0002] Foam plastics are a type of polymer material formed by a large number of gas micropores dispersed in solid plastics. They have the characteristics of light weight, heat insulation, sound absorption, shock absorption, and better dielectric properties than base resins, and have a wide range of uses.

[0003] In the production of foam plastic boards, one of the processes is to cut the foam plastic boards. The traditional cutting device mainly consists of a cutting table with an installed motor and a blade to complete the foam plastic cutting. However, when manually positioning and cutting the same batch of foam plastic boards, in most cases the staff judges the position of each cutting based on processing experience. This method produces a large error. Another common method is to pre-draw cutting lines on the foam plastic. Although this method has a smaller error, the process is more cumbersome. As a result, the existing traditional cutting devices of this type are relatively limited in actual use.

[0004] Therefore, those skilled in the art provide a foam plastic cutting device to solve the problems raised in the above background technology. Utility Model Content

[0008] Connecting rods are fixedly connected on both sides of the lower surface of the cutting table, and a scale cross bar is fixedly connected between the outsides of the two connecting rods. A U-shaped frame is sleeved on the outside of the scale cross bar, and a limiting nut is threadedly connected to the bottom of the U-shaped frame, and one end of the outer side of the limiting nut passes through the inside of the scale cross bar.

[0010] Preferably, an observation plate is fixedly connected to the middle position below the U-shaped frame, and the outer portion of the observation plate is attached to one side of the scale value of the scale cross bar.

[0011] Preferably, a plurality of through holes of a size matching the end of the limit nut are equidistantly provided inside the scale cross bar.

[0012] Preferably, two corners on one side of the cutting table are rotatably connected with bidirectional screw rods, and two ends of the outer side of the bidirectional screw rod are respectively spirally driven with the corresponding corners of the positioning baffles on both sides, and the positioning baffles are attached to the outside of the cutting table.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments 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 in 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.

[0022] like Figure 1-Figure 4 As shown, the present application discloses a foam plastic cutting device, in which a cutting table 4 and supporting legs 3 installed at four corners of the lower surface of the cutting table 4 provide support for the entire device, and positioning baffles 2 are installed on both sides of the upper surface of the cutting table 4. A rectangular notch is opened inside the cutting table 4, and a columnar gear rod 5 is rotatably connected in the notch of the cutting table 4. A blade 8 is sleeved on the outside of the columnar gear rod 5. The columnar gear rod 5 is composed of a cylindrical member and a plurality of rectangular protrusions integrally formed at equal angles on the outside of the cylindrical member, so that the blade 8 can move laterally outside the columnar gear rod 5, and at the same time, the blade 8 can rotate synchronously with the columnar gear rod 5.

[0023] A driving motor 1 is installed on one side of the cutting table 4, and the output end of the driving motor 1 extends to the notch and is fixed to one end of the columnar gear rod 5. The driving motor 1 can be started so that the output end of the driving motor 1 drives the columnar gear rod 5 to rotate, and then the columnar gear rod 5 drives the blade 8 to rotate at high speed in the notch of the cutting table 4 during rotation, so as to achieve cutting of the material. At the same time, connecting rods 11 are fixedly connected on both sides of the lower surface of the cutting table 4, and a scale cross bar 6 is fixedly connected between the outer parts of the two connecting rods 11. A U-shaped frame 7 is sleeved on the outer part of the scale cross bar 6, and a limiting mechanism for limiting the blade 8 is arranged inside the U-shaped frame 7. The limiting mechanism enables the U-shaped frame 7 to drive the blade 8 to move horizontally. At the same time, a limiting nut 16 is threadedly connected under the U-shaped frame 7, and one end of the outer part of the limiting nut 16 passes through the interior of the scale cross bar 6, so as to limit the U-shaped frame 7 and ensure that the blade 8 is stable after adjustment.

[0024] like Figure 4As shown, the limiting mechanism in the device includes two connecting shafts 14 and two abutting circular plates 13. The two connecting shafts 14 are fixed at the two ends of the U-shaped frame 7. The two abutting circular plates 13 are rotatably connected to the corresponding ends of the connecting shafts 14, and the abutting circular plates 13 are attached to the outside of the blade 8, so that the blade 8 can move synchronously with the U-shaped frame 7, which is convenient for adjusting the installation position of the blade 8. At the same time, the abutting circular plates 13 on both sides can rotate synchronously with the blade 8 to avoid affecting the cutting of the material by the blade 8.

[0025] like Figure 3 and Figure 4 As shown, in the device, an observation plate 15 is fixedly connected to the middle position below the U-shaped frame 7, and the outside of the observation plate 15 is attached to the scale value side of the scale cross bar 6. At the same time, the observation plate 15 is consistent in thickness with the blade 8, so that the observation plate 15 can move along with the U-shaped frame 7 on the scale value side of the scale cross bar 6, which is convenient for the staff to determine the cutting position to be set by the blade 8 through the observation plate 15.

[0026] like Figure 4 As shown, in the device, a plurality of through holes 12 of a size matching the end of a limit nut 16 are equidistantly provided inside the scale cross bar 6. Within a certain adjustment range, after the blade 8 is adjusted to its installation position, the limit nut 16 can be screwed through the corresponding through hole 12 to limit the blade 8 in time.

[0027] like Figure 1 and Figure 2 As shown, in the device, two corners on one side of the cutting table 4 are rotatably connected with a bidirectional screw rod 9, and the outer ends of the bidirectional screw rod 9 are respectively spirally driven with the corresponding corners of the positioning baffles 2 on both sides, and the positioning baffles 2 are attached to the outside of the cutting table 4. By rotating the handle end of the bidirectional screw rod 9, the positioning baffles 2 on both sides are driven to move toward or away from each other on the upper surface of the cutting table 4, which is convenient for the preliminary positioning of materials of more different specifications.

[0028] like Figure 1 and Figure 2 As shown, in this device, fixing rods 10 are fixedly connected at the two corners of the cutting table 4 away from the bidirectional screw rod 9, and the outside of the fixing rods 10 passes through the corresponding corners of the two positioning baffles 2, so as to limit the other side of the positioning baffle 2 and ensure the stability of the positioning baffle 2 when it moves in contact with the upper surface of the cutting table 4.

[0029] The standard parts used in the utility model can all be purchased from the market, and special-shaped parts can be customized according to the instructions and the drawings. The specific connection methods of each part adopt the conventional means such as mature bolts, rivets, welding, etc. in the existing technology. The machinery, parts and equipment all adopt the conventional models in the existing technology, and the circuit connection adopts the conventional connection method in the existing technology, which will not be described in detail here.

[0030] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0031] The implementation principle of the foam plastic cutting device of the embodiment of the present application is as follows: when in use, the bidirectional screw rod 9 is rotated in advance according to the size of the material. Since the threads on both sides of the bidirectional screw rod 9 are in opposite directions, the bidirectional screw rod 9 can then synchronously drive the positioning baffles 2 on both sides to move toward each other, so that the positioning baffles 2 on both sides can fit on both sides of the material, ensuring that the same batch of materials are placed at the same initial position on the upper surface of the cutting table 4, which is convenient for determining the subsequent cutting position;

[0032] Then, the U-shaped frame 7 can be driven by external force to move outside the scale cross bar 6, and then the U-shaped frame 7 can drive the connecting shaft 14 and the abutting circular plate 13 to move, and then the abutting circular plates 13 on both sides can drive the blade 8 to move outside the columnar gear rod 5. At the same time, the staff can observe the movement of the observation plate 15 on the scale value side of the scale cross bar 6 to determine the cutting position of the blade 8 on the material, and then screw the limit nut 16 through the corresponding through-hole 12 to limit the U-shaped frame 7 and ensure the stability of the blade 8 after adjusting the position. Finally, the staff can place the material between the preset columnar gear rods 5 on both sides in turn, and then push the material to move on the upper surface of the cutting table 4 to complete a more accurately positioned cutting of the same batch of materials.

[0033] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
