Description

Technical Field

[0001] The utility model relates to a segment cutting device, in particular to an automatic segment cutting device for extruded blanks. Background Art

[0002] At present, there is no suitable cutting method for silicon carbide filter material blanks except abrasion in the current production process because of the self-sharpening and high hardness of the material itself (silicon carbide hardness is comparable to diamond).

[0003] Moreover, due to the thin-walled porous structure of the silicon carbide filter material itself, and the material itself contains a certain amount of moisture during extrusion, the presence of this moisture is not beneficial to the filter material itself. If it is not cut into segments in time during the continuous extrusion process, the material will deform under the influence of multiple factors such as moisture and gravity.

[0004] At present, the main method of cutting silicon carbide filter material blanks into segments is to use filaments, such as high-strength fishing lines or other materials. After the material is extruded to a certain length, a constant tension is applied to both ends of the wire, and the wire is moved to quickly cut through the blank along the radial direction of the blank, so as to achieve the purpose of dividing the blank into segments. However, this cutting method has the following disadvantages: the length of the cut segments is different. The existing technology uses filaments for cutting, and the cutting judgment standard is visual, that is, the blank reaches a certain length visually, and the employee holds the filament to cut and segment. Therefore, under the influence of human factors, the length of the split cut will be inconsistent, resulting in the inevitable waste of some raw materials. The slow cutting speed causes the blank to deform. Due to the particularity of the structure of the silicon carbide filter material itself, the material itself does not have good shape self-sustaining properties in the initial stage of extrusion. When using wire cutting, the blank is deformed in the direction of the force under the influence of external force, and even the material itself is damaged. Many people are required during the cutting process, and there are also certain safety risks, which increases invisible costs. Utility Model Content

The first direction, the second direction, and the third direction are defined as mutually perpendicular directions, wherein the first direction is X, the second direction is Y, and the third direction is Z.

[0024] The frame 103 is arranged at the top of the first bracket, and the second sliding device 2 is arranged at the bottom of the frame 103. The second sliding device 2 includes a second slide rail 201, a second slider 202, a second push block 203, and a second telescopic member 204. The second slide rail 201 is arranged at the top of the first bracket 101, and the second slider 202 is slidably connected in the second slide rail 201. The movable end of the second telescopic member 204 is connected to the second push block 203, and the second push block 203 is connected to the bottom of the frame 103. The second telescopic member 204 drives the frame 103 to reciprocate in the first direction. The second sliding device 2 is used to drive the frame 103 to reciprocate in the first direction. When the second telescopic member 204 retracts, the second telescopic member 204 drives the frame 103 to approach the conveying assembly 7, thereby driving the cutting assembly 4 to move.

[0025] The cutting assembly 4 includes a first sliding device 3, a sensor 407, a wire tensioner 405, a cutting wire 402, a wire column 403, and a material judgment switch 406.

When the blank 8 enters, it first passes through the material approaching judgment switch 406. Then, when the blank 8 reaches the adjusted length judgment switch, the cutting component 4 turns on the action switch to release the limit and reciprocates along the second direction for cutting. When the first telescopic member 303 pushes the first push block 304 to the tail end, the cutting component 4 stops and starts the conveying component 7 to quickly convey the blank 8 to the first direction.

[0027] The clamping assembly 5 includes a clamping plate 501, a third telescopic member 502, and an air-drying detector installed on both sides of the guide plate 105.

The air-drying detector is arranged in the clamping plate 501. After the blank 8 is cut, it is driven into the clamping assembly 5 through the conveying assembly 7. After the air-drying sensor 407 detects that the blank 8 has entered, the clamping assembly 5 moves inward to clamp the blank 8.

[0028] The air supply assembly 6 includes a blowing head 601, a movable plate 602, a fourth telescopic member 603, a third slide rail 605, and a second frame 604. The third slide rail 605 is arranged on one side of the guide plate 105, and the second frame 604 is slidably connected to the third slide rail 605, and the second frame 604 can reciprocate in the first direction through the third slide rail 605.

When the blank 8 enters the conveyor belt 701, it is processed by the air supply assembly 6 and transported to the tail end for removal by the staff.

[0030] The specific usage method of this embodiment is:

[0031] The material judgment switch 406 and the length sensing judgment are the prerequisites for opening the cutting assembly 4. When both the material judgment switch 406 and the sensor 407 have signals, they are used as the opening standard of the cutting assembly 4. The second telescopic member 204 provides a horizontal first direction movement with the same speed and direction as the material discharge. At the same time, the cutting assembly 4 moves along the second direction to complete the cutting action. When the cutting action is completed, the cutting in place signal is triggered. This signal is triggered, the cutting assembly 4 stops, and the conveying assembly 7 is opened at the same time. The first telescopic member 303 pushes the push block to the top and then reaches the stop point, and the action is completed.

[0032] After the cutting assembly 4 cuts into segments, the material is continuously extruded, and the cutting assembly 4 cannot return to the original position of the cutting initial point. The blank 8 to be segmented is driven away quickly by the conveying assembly 7, and the frame 103 carries the cutting assembly 4 to quickly cross the cutting surface in the same direction along the first direction. The linear speed of the conveying assembly 7 is greater than the linear speed of the cutting assembly 4 moving in the first direction, so as to achieve the purpose of quickly crossing the cutting plane.

[0033] When the frame 103 moves along the first direction to reach the designated position, a signal is sent after the second telescopic member 204 pushes the second push block 203 to the position, and the signal is used as a start signal for the frame 103 to quickly return to the initial position in the second direction. When the frame 103 returns to the initial horizontal position in the second direction, the trigger position arrival signal is triggered, and the cutting assembly 4 returns to the initial position.

[0034] The segmented blank 8 reaches the predetermined position for air drying under the drive of the conveying assembly 7, and the motion sensing switch generates a signal to start the clamping assembly 5. After the clamping assembly 5 moves to the right position, it maintains the shape of the blank 8 and starts the air supply assembly 6. The air supply assembly 6 uses a time relay, and stops the air supply after the set time is reached. When the air supply stops, the clamping hand releases the blank 8. The conveying assembly 7 conveys to the tail end, and the employee takes away the blank 8, which marks the end of a cycle.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. 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.
