[0022] The utility model is further described below in combination with the drawings.

[0023] The directions involved in the specification are accurate when the device for detecting rubber material with cooked rubber and cutting of the utility model works normally, are not limited to the directions when it is stored and transported, and only represent relative positional relationship, not absolute positional relationship.

[0024] As Figure 1 , Figure 2 and Figure 3 are shown in the drawings, a device for detecting rubber material with cooked rubber and cutting, including front and rear setting's front conveying line 1 and rear conveying line 2 and with front conveying line 1 and rear conveying line 2 signal connection's control system, control system controls the operation of front conveying line 1 and rear conveying line 2. After the rubber sheet 5 of banburying and open mixing is conveyed through front conveying line 1 and rear conveying line 2 in turn, then carries out the material collection.

[0025] A gap is defined between the end of the front conveyor line 1 and the front end of the rear conveyor line 2. A waste box is located at the bottom of the gap to collect any rubber pieces containing impurities that are subsequently cut. Above the front conveyor line 1, a vision module 3 is installed to detect impurities on the film above it, and a cutting device 4 is installed to cut any rubber pieces containing impurities from the film 5. Both vision module 3 and cutting device 4 are connected to a control system. Vision module 3 includes a scanning device fixed above the front conveyor line 1. The scanning device scans the film 5 passing beneath it, and the scanned film image is transmitted to the control system. The control system is also connected to an alarm system.

[0026] like Figure 2 、 Figure 3 and Figure 4 As shown, the cutting device 4 includes a fixed frame 41 fixed to the left and right sides of the front conveyor line 1, a cutter assembly 42 movably mounted on the fixed frame 41, and a cutting drive 43 that drives the cutter assembly 42 to move. The cutter assembly 42 can be a hole opener or a punch, etc., and the cutting drive 43 controls the cutter assembly 42 to move accordingly to complete the cutting. If the cutter assembly 42 is a hole opener, the cutting drive 43 needs to drive the cutter assembly 42 to rotate and descend during cutting, thereby achieving rotary cutting of the film 5. To ensure a more regular and beautiful cut and avoid debris, the cutter assembly 42 in this embodiment includes a punch 421 and an anvil 422 arranged in an upper and lower position. The punch 421 includes a punch body with an open bottom formed by blades. The central enclosed area formed by the blades forms a punch cavity; the bottom of the punch cavity forms a blade edge; the blade edge contacts the film 5. The punch blade 421 can be square, circular, or elliptical in shape; in this embodiment, a circular or elliptical shape is preferred to minimize its angle and facilitate the removal of impurities from the punch cavity. The cutting drive 43 includes a sliding drive that controls the left and right sliding of the punch blade 421 and a lifting drive that controls the elevation of the punch blade 421. The cutting area of ​​the punch blade 421 is covered by an anvil 422; the film 5 passes between the punch blade 421 and the anvil 422.

[0027] The fixed frame 41 includes a left bracket and a right bracket. The left bracket is fixed to the left side of the front conveyor line 1, and the right bracket is fixed to the right side of the front conveyor line 1. A sliding rod 411 is fixedly installed between the left and right brackets. A sliding bracket 423 is slidably mounted on the sliding rod 411. The sliding bracket 423 has a sliding hole for the sliding rod 411 to pass through, and the sliding bracket 423 is slidably mounted on the sliding rod 411. To facilitate smoother sliding, a sliding sleeve is fixedly installed in the sliding hole, and the sliding sleeve is slidably mounted on the sliding rod 411. Two sliding rods 411 are provided, and the two sliding rods 411 are located on the upper and lower sides of the sliding bracket 423 respectively.

[0028] The slide drive device includes a lead screw 431 rotatably mounted between the left and right brackets, and a motor 432 that drives lead screw 431. A lead screw nut is threaded onto lead screw 431, which is then fixed to slide 423. The operation of motor 432 rotates lead screw 431, which in turn drives the lead screw nut to move left and right, thereby achieving left and right movement of slide 423.

[0029] A punching knife mounting frame 424 and a lifting drive device for driving the punching knife mounting frame 424 to move up and down are installed on the slide 423 ; the punching knife 421 is fixedly installed at the bottom of the punching knife mounting frame 424 .

[0030] In this embodiment, the lifting drive device is an electric cylinder 433, but in actual applications, it can also be a pneumatic cylinder or an oil cylinder. The lifting drive device is fixed to the slide 423, and its output shaft is fixed downwardly above the punching blade mounting frame 424. The extension and retraction of the lifting drive device drives the punching blade mounting frame 424 to move upward and downward, thereby enabling the punching blade 421 to punch downward on the film 5. To ensure stable lifting and lowering of the punching blade mounting frame 424, guide rods are provided on both sides of the lifting drive device, and the guide rods are mounted on the slide 423 for vertical sliding.

[0031] As an improvement to the above embodiment, to ensure that the cut rubber block can be smoothly removed from the punch cavity and prevent sticking and accumulation of material within the cavity, an ejection device 425 is installed within the punch cavity. The ejection device 425 comprises an ejection plate 4251 that slides up and down within the punch cavity and a return spring 4252 clamped between the ejection plate 4251 and the top of the punch cavity. Under the action of the return spring, the ejection plate 4251 ejects the rubber block that has entered the punch cavity. To ensure the position of the ejection plate 4251, a telescopic rod is installed between the ejection plate 4251 and the top of the punch cavity. The telescopic rod provides guidance and a limit for the ejection plate 4251's movement, and the return spring 4252 is mounted on the outside of the telescopic rod. The provision of the ejection plate 4251 ensures that the punched rubber block can be quickly removed and retained in its hole, preventing it from sticking to the punch blade 421 and being lifted upward, supported above the film 5 and unable to escape through the gap.

[0032] A pressure block 45 is provided on the anvil 422 to keep the film 5 pressed against the upper surface of the anvil 422. The pressure block 45 spans the upper surface of the anvil 422. Two pressure blocks 45 are provided, one on each side of the punch 421. The film 5 slides in the gap between the pressure block 45 and the anvil 422. The pressure block 45 can be a square tube or a round shaft structure, and a round shaft structure is preferred in this embodiment.

[0033] The pressing block 45 ensures that the film 5 always rests on the anvil 422 to prevent it from lifting up with the lifting of the punch 421, causing the surface to bulge and affecting the material collection. At the same time, if an error occurs and the punched rubber block escapes from the punch hole, it cannot pass through the pressing block 45 and can be cleaned up in time manually.

[0034] like Figure 1-Figure 4 As shown together, the working process of the device for detecting whether the rubber material has cooked rubber and cutting it is as follows:

[0035] The first step is to implant the picture of cooked glue beans or the characteristics of cooked glue beans into the control system in advance; the visual module 3 transmits the scanned film image to the control system in real time, and the control system realizes automatic comparison and screening.

[0036] In the second step, when the visual module 3 detects that the film 5 contains impurities (cooked glue beans), the control system automatically obtains its coordinate position and controls the front conveyor line 1 to continue running. When the position of the cooked glue beans passes the cutting device 4, the control system controls the front conveyor line 1 and the rear conveyor line 2 to stop running; the film 5 stops moving forward.

[0037] In the third step, the control system continues to control the cutting device 4 to cut the impurities. Specifically, the control system controls the sliding drive device to move left and right according to the left and right movement in the second step, controlling the punching knife 421 to be positioned above the rubber block containing impurities; the lifting drive device controls the lifting and lowering of the punching knife 421 to perform punching. During punching, as the punching knife 421 is gradually pressed down, the blade of the punching knife 421 acts on the film 5, and the rubber block containing impurities is gradually flushed down and enters the punching cavity, exerting an upward thrust on the ejection plate 4251. The ejection plate 4251 compresses the return spring 4252, and the ejection plate 4251 gradually rises; when the bottom of the punching knife 421 contacts the anvil 422, the cutting is completed; the punching knife 421 rises, and at this time, the rubber block in the punching cavity is ejected by the ejection plate 4251 and does not rise as the punching knife 421 rises; it continues to stay in the punching hole.

[0038] Step 4. During the third step, the control system synchronously transmits the signal to the alarm system. The alarm system sounds an alarm. The staff monitors the cutting situation of the system in a timely manner according to the alarm situation to prevent miscutting. After the punching is completed, the front conveyor line 1 and the rear conveyor line 2 continue to run, and the rubber block containing impurities continues to move forward with the film 5. When passing through the leakage gap, it leaks out of the leakage gap.

[0039] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
