[0022] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0023] In order to solve the problem of inconvenience in removing metal impurities from an extruder in the prior art, the present invention also provides an extruder removing device and an extruder.

[0024] The extruder further includes an extruder rejecting device, which is arranged on the conveying component 10 to detect metal on the rubber material of the conveying component 10 and remove the rubber material with metal.

[0025] Please refer to Figures 1 to 3 An extruder rejection device includes a second detection component 11, a transfer component 50, and a cutting component 40. The second detection component 11 is arranged on the conveying component 10 of the extruder to detect impurities in the rubber material on the conveying component 10; the cutting component 40 is arranged on the conveying component 10 to cut the rubber material on the conveying component 10 when the second detection component 11 detects impurities in the rubber material on the conveying component 10; the transfer component 50 is arranged on the conveying component 10 to remove the rubber material with impurities after being cut by the cutting component 40.

[0026] The extruder rejection device of the present invention is generally arranged on the extruder feeding component to detect the quality of the rubber material when the rubber material is loaded and to cut and remove the unqualified rubber material in time. The present invention mainly introduces a method for removing rubber material containing metal impurities. Specifically, a second detection component 11 for detecting metal is first arranged on the transmission component 10. In addition, a cutting component 40 for cutting the rubber material and a transfer component 50 for moving the cut rubber material out of the transmission component 10 are also arranged. For ease of control, the extruder rejection device is also provided with a controller. After receiving the signal from the second detection component 11, the controller controls the cutting component 40 to cut the rubber material, and then controls the transfer component 50 to transfer the cut rubber material to a preset position to prevent it from entering the feeding hopper 21 of the extruder, thereby replacing the problem of manual cutting of the rubber material and improving work efficiency and the quality of the rubber material.

[0027] The transfer assembly 50 includes: a swinging roller 51, which is movably arranged on the conveying assembly 10, wherein the swinging roller 51 has a transfer position and a working position. When the swinging roller 51 moves to the working position, the rubber material is transferred to the screw assembly 20 of the extruder, or when the swinging roller 51 moves to the transfer position, the rubber material is transferred to a preset position.

[0028] like Figures 1 to 3 The position of the swing roller 51 in different working states is shown. Figure 1 and Figure 3 The positions in the middle are the same, both are working positions. At this position, the swing roller 51 transfers the rubber material to the feeding hopper 21. Figure 2 The figure shows the swinging roller 51 in its transfer position. At this point, the swinging roller 51 transfers the rubber material to a pre-set receiving tray to recover the rubber material with metallic impurities. In this embodiment, the swinging roller 51 is positioned at the end of the conveyor assembly 10 near the feed hopper 21 and is rotatably connected to the conveyor assembly 10 for rotation between a working position and a transfer position. The swinging guide roller is provided with a plurality of guide rollers spaced apart along the guide direction. The end of the swinging roller 51, away from the conveyor assembly 10, is curved to ensure a smooth transition of the rubber material into the feed hopper 21, preventing stress concentration caused by the sudden transition at this location.

[0029] The extruder rejection device also includes: a second drive assembly 52, which is drivably connected to the swing roller 51 to drive the swing roller 51 to move. The second drive assembly 52 includes a second drive cylinder, which is disposed at the bottom of the conveying assembly 10. The swing roller 51 is rotatably disposed at one end of the conveying assembly 10 near the screw assembly 20, wherein the second drive cylinder is drivably connected to the swing roller 51 to drive the swing roller 51 to rotate between the transfer position and the working position.

[0030] like Figures 1 to 3 As shown, in this embodiment, in order to facilitate the control of the rotation of the swing roller 51, a mounting bracket is provided under the end of the conveying assembly 10 for installing the second driving cylinder. The second driving cylinder is hinged to the end of the swing roller 51 away from the conveying assembly 10 to drive the swing roller 51 to rotate relative to the conveying assembly 10, thereby moving back and forth between the working position and the transfer position. The second driving cylinder is provided under the conveying assembly 10 without taking up space and avoiding interference with the movement of the rubber material.

[0031] The cutting assembly 40 includes a rotary motor 41 and a rotary knife 42 . The rotary motor 41 is disposed on the conveying assembly 10 . The rotary knife 42 is drive-connected to the rotary motor 41 so as to rotate under the drive of the rotary motor 41 to cut the rubber material.

[0032] like Figures 1 to 3 As shown, the cutting component 40 in this embodiment adopts a rotary knife 42, so that friction can be minimized when cutting the rubber material, avoiding the rubber material being entangled in the rotary knife 42 or the rotary motor 41 to cause jamming, or the rubber material cannot be cut.

[0033] The extruder rejection device further includes a rotary base, which is movably disposed on the conveying assembly 10 , wherein the cutting assembly 40 is disposed on the rotary base, and the rotary base drives the cutting assembly 40 to move along the width direction of the rubber material to cut the rubber material.

[0034] The swivel base is arranged on the top of the conveying assembly 10, spanning the conveyor belt on the conveying assembly 10, and the cutting assembly 40 is arranged on the swivel base. In addition, the rejection device is also provided with a track spanning the conveyor belt on the conveying assembly 10, and the swivel base is movably arranged to move on the track. When the cutting assembly 40 is cutting, the rotary knife 42 rotates for cutting, and the motor drives the swivel base to move along the track to cut the rubber material horizontally.

[0035] In order to solve the problem in the prior art that the film cutting device is prone to damaging the conveying assembly 10 when cutting the film on the conveyor belt, the present invention further provides a film cutting device and an extruder.

[0036] Please refer to Figures 4 to 6 A film cutting device includes: a grabbing component 60, which is used to grab the film on the conveying component 10 to separate the film from the conveying component 10; and a cutting component 40, which is used to cut the film grabbed by the grabbing component 60.

[0037] The film cutting device provided by the present invention is used to cut the film during the film transportation process. The film cutting device is arranged on the conveying component 10. The film moves along a predetermined direction driven by the conveyor belt of the conveying component 10. When unqualified film is detected, the controller controls the film cutting device to cut the film. During cutting, the grabbing component 60 first grabs the film on the conveyor belt, lifts the film off the conveyor belt, and then the cutting component 40 cuts the film off the conveyor belt. This avoids the problem of damaging the conveyor belt. At the same time, after the film is lifted, the film stops moving. The cutting component 40 can neatly cut the film without moving with the film during cutting.

[0038] The film cutting device also includes: a third driving cylinder 43, which is connected to both the cutting component 40 and the grabbing component 60 to simultaneously drive the cutting component 40 and the grabbing component 60 to approach or move away from the conveying component 10, wherein the grabbing component 60 has a grabbing position and an avoidance position. When the grabbing component 60 moves to the grabbing position, it grabs the film on the conveying component 10. When the grabbing component 60 moves to the avoidance position, the cutting component 40 cuts the film.

[0039] like Figure 4 As shown, in this embodiment, a fixed seat is provided on the conveying component 10, and the grabbing component 60 and the cutting component 40 are both fixed on the fixed seat. The fixed seat spans the conveyor belt along the width direction of the conveyor belt and is arranged above the conveyor belt. The third driving cylinder 43 is arranged on the fixed seat. The third driving cylinder 43 drives the cutting component 40 and the grabbing component 60 to move close to the conveyor belt so that the grabbing component 60 grabs the film on the conveyor belt and drives the film away from the conveyor belt.

[0040] The gripper assembly 60 includes a fixed base mounted on the conveyor assembly 10 and a suction cup mechanism 61 movably mounted on the fixed base for sucking up the film. The gripper assembly 60 also includes a fourth drive cylinder 62 operatively connected to the suction cup mechanism 61 to drive the suction cup mechanism 61 toward and suck up the film. The suction cup mechanism 61 includes multiple suction cups spaced apart along the film's direction of travel to simultaneously grab the film.

[0041] like Figure 4As shown, the specific structure of the grabbing assembly 60 is introduced in this embodiment. The grabbing assembly 60 grabs the film on the conveyor belt through the suction cup mechanism 61. Specifically, when the third driving cylinder 43 drives the grabbing assembly 60 to move to the grabbing position, the fourth driving cylinder 62 drives the suction cup mechanism 61 to move down to contact the film, and then the vacuum mechanism works to suck the film through the suction cup mechanism 61. In order to prevent the suction cup mechanism 61 of the cutting assembly 40 from failing to hold the film firmly during the cutting process, the suction cup mechanism 61 is provided with multiple suction cups, and the multiple suction cups are arranged at intervals along the moving direction of the film. The multiple suction cups simultaneously suck different positions of the film to grab the film.

[0042] The gripper assembly 60 further includes an adjustment mechanism 63 connected to the suction cup mechanism 61 to adjust the position of the suction cup mechanism 61 according to the position of the film on the transport assembly 10. The adjustment mechanism 63 includes an adjustment motor and an adjustment screw 631. The adjustment screw 631 is drivingly connected to the adjustment motor, and the suction cup mechanism 61 is connected to the adjustment screw 631. The adjustment motor drives the adjustment screw 631 to rotate, thereby driving the suction cup mechanism 61 to move along the width direction of the film.

[0043] like Figure 4 As shown, in order to prevent the suction cup mechanism 61 from grabbing the film, the grabbing assembly 60 in this embodiment is also provided with a detection sensor to detect the position of the film on the conveyor belt. The detection sensor transmits the detected position of the film to the controller, and the controller controls the adjustment motor to rotate to drive the adjustment screw 631 to rotate, thereby driving the suction cup mechanism 61 to move along the width direction of the conveyor belt until it is located directly above the film, and then reaches down to grab the film.

[0044] Preferably, there are two adjusting screws 631 , which are respectively arranged on both sides of the suction cup mechanism 61 .

[0045] Preferably, the adjustment mechanism 63 further includes a guide rod 632 , and the suction cup mechanism moves along the width direction of the conveyor belt along the guiding direction of the guide rod 632 .

[0046] The cutting assembly 40 includes: a fixed base, which is disposed on the conveying assembly 10; a rotary motor 41, which is disposed on the fixed base; and a rotary knife 42, which is connected to the rotary motor 41 and rotates under the drive of the rotary motor 41 to cut the film. The cutting assembly 40 also includes: a fifth driving cylinder 44, which is connected to the rotary motor 41 to drive the rotary knife 42 to approach the film via the rotary motor 41. The cutting assembly 40 also includes: a guide rail 45, which is disposed on the fixed base and extends along the width direction of the film, wherein the rotary knife 42 is movably disposed on the guide rail 45 to cut the film along the guide direction of the guide rail 45.

[0047] like Figure 5As shown, in this embodiment, an implementation structure of a cutting component 40 is provided. Specifically, the cutting component 40 cuts the rubber strip by a rotating cutting method. After the grabbing component 60 grabs the rubber strip, the fifth driving cylinder 44 drives the rotary knife 42 to approach the film, and then the rotary motor 41 drives the rotary knife 42 to rotate to cut the rubber strip. During the cutting process, the driving motor also moves the rotary knife 42 along the guide direction of the guide rail 45, so that the rotary knife 42 cuts the rubber strip along the width direction of the rubber strip.

[0048] An extruder includes a conveying component 10, a film cutting device and a screw component 20. The conveying component 10 is provided with a conveyor belt to transport the film into the screw component 20. The film cutting device is arranged on the conveying component 10 to cut the film on the conveyor belt, wherein the film cutting device is the above-mentioned film cutting device.

[0049] The second detection component 11 includes a metal detector, which is disposed at the top of the conveying component 10 to detect metal impurities in the rubber material.

[0050] In this embodiment, the main purpose is to detect whether the rubber is mixed with metal to prevent equipment damage during the subsequent extrusion or calendering process and affect the quality of the subsequent film. Therefore, the second detection component 11 uses a technical detector to detect whether there is metal in the rubber.

[0051] An extruder includes a feeding device and a screw assembly 20. The feeding device includes a conveyor assembly 10 for conveying rubber material into the screw assembly 20 for extrusion. The extruder also includes an extruder rejection device, which is the extruder rejection device described above. The extruder also includes a feeding hopper 21, which is located at the inlet of the screw assembly 20. The material guide assembly of the extruder feeding device transfers the rubber material from the conveyor assembly 10 of the extruder feeding device into the feeding hopper 21 to feed the screw assembly 20.

[0052] The present invention also provides an overall extruder structure with the above-mentioned extruder rejection device, which includes a conveying component 10 and an existing extruder device. The feeding device transfers the rubber material into the extruder device through the conveyor belt in the conveying component 10. The extruder rejection device is used to detect whether the rubber material is qualified and whether it contains metal or other impurities, so as to reject unqualified rubber material, thereby ensuring the safety of subsequent equipment and the quality of the rubber material.

[0053] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0054] The extruder rejection device of the present invention is generally arranged on the extruder feeding component to detect the quality of the rubber material when the rubber material is fed and to cut and remove the unqualified rubber material in time.

Specifically, a second detection component 11 for detecting metal is first set on the transmission component 10. In addition, a cutting component 40 for cutting the rubber material and a transfer component 50 for moving the cut rubber material out of the transmission component 10 are also set. For ease of control, the extruder rejection device is also provided with a controller. After receiving the signal from the second detection component 11, the controller controls the cutting component 40 to cut the rubber material, and then controls the transfer component 50 to transfer the cut rubber material to a preset position to prevent it from entering the feeding hopper 21 of the extruder, thereby replacing the problem of manual cutting of the rubber material and improving work efficiency and the quality of the rubber material. Among them, the film is one type of rubber material.
