Description

Technical Field

[0001] The utility model relates to the technical field of slitting of casting machines, and specifically relates to a slitting device for trimming the edges of a casting machine. Background Art

[0002] A casting machine is a special device for manufacturing casting films. During the production process, it is necessary to perform high-temperature melting processing on raw materials under high-temperature conditions to make the raw materials have a certain plasticity, and then form a film through die head extrusion and roller calendering. The original factory is equipped with air-pressure hobs. When producing relatively thick films, during the process of trimming the edges by the hobs, film chips will be generated during the cutting between the upper and lower hobs. After the film is formed, static electricity is generated due to the friction of the guide rollers. The film chips cut and dropped by the hobs are adsorbed onto the film by static electricity, which is difficult to clean, and has a great impact on the quality and production efficiency of the casting film.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Embodiment 1

[0020] As Figures 1 to 4As shown in the figure, a slitting device for trimming the edges of a casting machine is installed on the rear frame of the traction machine of the casting equipment. It includes a reduction gearbox 1, a support base 2, and a cutter shaft 3. The axial direction of the cutter shaft 3 is perpendicular to the conveying direction of the film. One end of the cutter shaft 3 is connected to the output shaft of the reduction gearbox 1, and the other end is connected to the support base 2. Both the support base 2 and the reduction gearbox 1 are installed on the rear frame of the traction machine of the casting equipment. A number of cutter discs 4 are sleeved on the cutter shaft 3, and a blade 41 is connected to the bottom of the cutter disc 4. The housing of the reduction gearbox 1 and the support base 2 are both installed on the rear frame of the traction machine of the casting equipment by bolts. The corresponding number of cutter discs 4 is installed according to the slitting requirements. The input shaft of the reduction gearbox 1 is connected with a rotating handle 11. By rotating the rotating handle 11, the cutter shaft 3 is driven to rotate. The cutter shaft 3 drives the cutter disc 4 to rotate, and the cutter disc 4 drives the blade 41 to rotate, so that the blade 41 can rotate to the lower part to achieve the effect of trimming the edges. With its efficient, fast, and stable processing ability, it can greatly improve the processing speed and production efficiency. The traditional hob-type edge trimming machine cannot compare with the blade-type edge trimming machine of this application in terms of efficiency. Moreover, in the case of thick films, the hob method is prone to knife edge marks, resulting in waste of raw materials. Since the blade 41 can slice quickly and stably, the cutting debris is less, the adsorption amount of the debris is reduced, and thus the influence on the edge trimming of the film is reduced. Preferably, the blade can use a traditional utility knife blade, which reduces the cost.

[0021] Embodiment 2

[0022] On the basis of Embodiment 1, as Figure 1 and Figure 3 shown, one end of the cutter shaft 3 is rotatably connected to a mounting shaft 53. A circular hole for the mounting shaft 53 to pass through is opened on the support base 2. A support base rotating handle 21 is threadedly connected to the support base 2. The tail of the support base rotating handle 21 penetrates into the circular hole and abuts against the mounting shaft 53, sleeving the support base 2 on the mounting shaft 53, and then tightening the support base rotating handle 21 to make the support base rotating handle 21 tightly abut against the mounting shaft 53, thereby stably installing the support base 2 on the cutter shaft 3. Due to the rotational connection between the cutter shaft 3 and the mounting shaft 53, the cutter shaft 3 can smoothly drive the cutter disc 4 to rotate.

[0023] Embodiment 3

[0024] On the basis of Embodiment 2, as Figure 1 、 Figure 3 and Figure 4As shown in the figure, the tool shaft 3 adopts a hexagonal shaft. The tool disc 4 is provided with a hexagonal hole 45. The tool shaft 3 is fitted through the hexagonal hole 45. A tool disc rotation handle 44 is threadedly connected to the top of the tool disc 4. The tool disc rotation handle 44 is used to lock the tool disc 4 on the tool shaft 3. Threaded holes 46 and rectangular grooves 47 are sequentially communicated from top to bottom on the top of the tool disc 4. The rectangular groove 47 is communicated with the hexagonal hole 45. A tool disc pressing block 48 is slidably fitted in the rectangular groove 47. The threaded shaft of the tool disc rotation handle 44 is threadedly connected to the threaded hole 46, and the threaded shaft is rotatably connected to the tool disc pressing block 48 through a bearing. The tool disc pressing block 48 abuts against the tool shaft 3. The contact area with the tool shaft 3 is increased by the setting of the tool disc pressing block 48, so that the connection strength between the tool disc 4 and the tool shaft 3 is relatively high. Secondly, the bottom surface of the tool disc pressing block 48 abuts tightly against the tool shaft 3, and the top is located in the rectangular groove 47, thereby limiting the tool disc pressing block 48, and further well limiting the rotational offset of the tool disc 4; the operation is simple, and only by rotating the tool disc rotation handle 44, the tool disc pressing block 48 can be driven to move up and down to complete the tooling and disassembly of the tool disc 4.

[0025] Embodiment 4

[0026] On the basis of Embodiment 3, as Figure 3 and Figure 4 shown, a tool groove 49 is provided at the bottom of the tool disc 4. A blade pressing block 50 is arranged in the tool groove 49. A part of the blade 41 is arranged in the tool groove 49. The blade pressing block 50 moves closer to or away from the blade 41. The blade pressing block 50 is used to press the blade 41 on the tool disc 4. A blade pressing screw 43 is threadedly connected to one side of the tool disc 4. The tail of the blade pressing screw 43 penetrates into the tool groove 49 and is rotatably connected to the blade pressing block 50. By rotating the blade pressing screw 43, the blade pressing block 50 is driven to move closer to or away from the blade 41, so as to press the blade 41 on the tool disc 4. The detachable installation of the blade 41 facilitates the replacement of the blade 41. When the blade 41 is worn, the blade pressing bolt 43 can be loosened to replace the blade 41, ensuring that the trimming operation is not affected.

[0027] Furthermore, as Figure 4 shown, a strip-shaped protrusion 51 is arranged on one side of the blade 41, and a strip-shaped groove 52 is provided on one side of the blade pressing block 50. The strip-shaped protrusion 51 is fitted in the strip-shaped groove 52. The tooling strength of the blade 41 is enhanced through the cooperation of the strip-shaped protrusion 51 and the strip-shaped groove 52, ensuring that the blade 41 will not be offset under the rotation of the tool shaft 3.
