Technical Field

[0001] The invention relates to the field of rubber, in particular to a batch impurity removal process for natural rubber sheets. Background Art

[0002] Since natural rubber is collected from rubber trees, it is often mixed with impurities such as bark, dead leaves, ants, and insects, which affect the quality and grade of the rubber. Rubber sheets need to be cleaned before leaving the factory. The current method of cleaning impurities is to place the solidified rubber sheets one by one on the film viewing lamp, and then manually find and cut off the impurities; but the manual efficiency is low, and it is not easy to cut a hole in the middle of a flat rubber sheet with scissors. Summary of the invention

[0008] S4, the rubber sheet follows the conveying device to enter under the impurity removal device, and the control system calculates the current position of the rubber sheet through the position and time of the rubber sheet in the camera image in S3, combined with the current time and the speed of the conveying device, and then controls the impurity removal device to remove impurities on the rubber sheet.

[0009] S5. Collect the impurities removed in S4 into a waste storage device.

[0010] The rubber sheets after the impurities are removed in S6 and S4 fall into the storage tank along with the conveying device for storage.

The impurity removal device includes a movable block, an outer shell, an inner shell, a movable sheet, a triangular block, a movable rod, a spring sheet and a cutter; the movable block is movably connected to the top of the support frame through the electric screw mechanism to achieve movement in all directions of front, back, left and right; the outer shell is cylindrical, and its upper part is fixed on the movable block. The interior of the outer shell is a cavity structure, and a No. 1 through hole and a No. 2 through hole are respectively arranged on the top and bottom surfaces of the outer shell, and a No. 1 side hole is arranged on the rear side surface of the outer shell. The inner shell is cylindrical and has a cavity inside. The inner shell is located in the outer shell and is slidably connected thereto. The bottom end of the inner shell extends out from the No. 2 through hole. The top and bottom surfaces of the inner shell are respectively provided with No. 3 through holes and No. 4 through holes. A No. 2 side hole is provided on the rear side surface of the inner shell. The No. 2 side hole and the No. 1 side hole always intersect and are always connected. A No. 1 hinge block is provided on the inner wall of the No. 3 through hole. A No. 2 hinge block is provided on the front inner wall of the No. 4 through hole, and a limit block is provided on the rear inner wall of the No. 4 through hole. The movable sheet is provided on the No. 4 through hole. In the through hole, a gap is provided between the outer edge of the movable piece and the inner wall of the No. 4 through hole, the front end of the movable piece is hinged on the No. 2 hinge block, and the rear end of the movable piece is placed on the limit block, and the top surface of the movable piece is provided with an arc surface; the triangular block is fixed on the inner wall of the upper part of the outer shell, the movable rod is located in the inner shell, the middle part of the movable rod is hinged on the No. 1 hinge block, the top end of the movable rod passes through the No. 3 through hole and rests on the triangular block, and the bottom end of the movable rod rests on the arc surface. Since the distance from any point on the arc to the center of the circle is equal, the bottom end of the movable rod still slides on the arc surface It has been resisting the movable sheet so that it cannot move; one end of the spring sheet is fixed on the inner wall of the inner shell, and the other end of the spring sheet is connected to the movable rod, and the spring sheet is used to reset the movable rod; the cutter is arranged on the bottom surface of the inner shell; an electric motor is arranged on the movable block, and the output end of the motor is connected to a crank-connecting rod mechanism through a gear pair, and the end of the connecting rod in the crank-connecting rod mechanism away from the crank passes through the No. 1 through hole and is hinged to the top of the inner shell, and the resulting motor can drive the inner shell to move up and down when it is running, thereby driving the cutter to move up and down.

[0014] The waste material collecting and storing device is arranged on the supporting frame, and the waste material collecting and storing device is connected with the No. 1 side hole through a pipeline.

[0015] The material storage trough is arranged on the ground at the rear end of the conveying device; the control system is electrically connected with the camera device and the electric screw mechanism respectively.

[0016] Preferably, the camera device includes a scanning frame and a recognition camera. The scanning frame is fixed on the ground. The scanning frame is a frame structure with an illumination lamp inside. A scanning camera is arranged on the inner wall of the top surface of the scanning frame. The light of the illumination lamp passes through the No. 1 conveyor belt and the rubber sheet, and then the image is collected by the scanning camera. The recognition camera is arranged on the front side of the support frame. The recognition camera is used to finally identify the rubber sheet to be processed and compare it with the data obtained by the scanning camera, so as to confirm the number of the rubber sheet, as well as the position and posture of the rubber sheet, to avoid the movement and tilt of the rubber sheet during the transmission process, resulting in errors in the subsequent impurity removal position. Since the image collected by the scanning camera is penetrating light, and the image collected by the recognition camera is reflected light, if the recognition camera is to accurately identify the rubber sheet number, a camera that collects reflected light at the same time can also be added to the scanning frame. The scanning camera is only used to determine the distribution of impurities.

[0017] The conveying device includes conveyor belt No. 1 and conveyor belt No. 2. The conveyor belt No. 1 is made of transparent material to facilitate the passage of lighting. The rear end of the conveyor belt No. 1 passes through the scanning frame; the front end of the conveyor belt No. 2 is close to the rear end of the conveyor belt No. 1, and a support platform is arranged between the upper and lower belt surfaces of the conveyor belt No. 2, and the support platform is fixed on the ground.

[0018] Preferably, the waste storage device comprises a box body, a No. 3 side hole, a transmission hose, a No. 4 side hole, a barrier, an air pump, a three-way valve and a baffle; the box body is fixed on the support frame, and a ventilation hole is arranged on the top surface of the box body; the No. 3 side hole is arranged on the top of the front side of the box body; the two ends of the transmission hose are respectively connected with the No. 1 side hole and the No. 3 side hole; the No. 4 side hole is arranged at the bottom of the rear side of the box body; the barrier is obliquely arranged on the inner wall of the box body, and the barrier is located between the ventilation hole and the inner cavity of the box body, and is used to push the rubber sheet impurities down and drop them to the bottom of the box body; the air pump is installed on the top surface of the box body; the three-way valve is arranged on the top surface of the box body, and the three-way valve is connected with the air pump, the ventilation hole and the ambient air respectively, and the air pump draws out the air in the box body through the three-way valve and discharges it to the outside air; the baffle is hinged on the rear outer wall of the box body and covers the No. 4 side hole, and the stored rubber sheet impurities can be taken out by opening the baffle.

[0019] Preferably, the motor is a stepper motor, and the three-way valve is an electromagnetic three-way valve. The motor and the three-way valve are both electrically connected to the control system. The position of the inner shell at this time can be calculated by calculating the number of motor steps, thereby determining the position of the cutter at this time. The control system regulates the opening and closing of the valve in the three-way valve, so that the suction on the rubber sheet under the cutter is suspended when the cutter cuts down, and the suction on the rubber sheet is restored when the cutter rises, thereby avoiding unnecessary suction that causes the rubber sheet to move and thus mispositioning impurities thereafter.

[0020] Preferably, the top surface of the limit block is an inclined surface; and a building block with an inclined bottom surface is fixedly provided at the rear end of the movable sheet, and the building block is placed on the limit block and fits therewith.

[0021] Preferably, a mask is further provided in the inner cavity of the outer shell, the bottom of the mask is an opening, and the mask covers the outside of the triangular block. The mask can isolate the triangular block to keep it clean.

[0022] Preferably, the cross-sections of the outer shell and the inner shell are both square, the cutter is in a square frame shape, and the rubber hole cut by the square cutter is also square. When cutting impurities of a larger area, the square cut makes it easier to calculate the punching path and the overlapping area of ​​the cut is small. In addition, even a metal conveyor belt will be deformed and uneven after long-term use. Therefore, in order to avoid the cutter from contacting with the conveyor belt and damaging the conveyor belt, and to avoid the conveyor belt from being uneven after long-term use, and to improve the fault tolerance of production and processing, a gap will be left between the cutter and the conveyor belt when it moves to the lowest point, and the impurities of the rubber sheet that are not completely cut off rely on the suction of the air pump and the lifting of the inner shell to completely separate them from the rubber sheet.

[0023] The beneficial effects of the present invention are:

[0024] (1) A natural rubber sheet batch impurity removal process of the present invention uses a camera to capture a video of the rubber sheet, and then a control system analyzes the video to determine the location of impurities on the rubber sheet, which are then removed at a fixed point by an impurity removal device. The entire process does not require manual labor, and production efficiency is improved.

[0025] (2) In the present invention, the bottom end of the movable rod is against the arc surface. On the one hand, since the distance from any point on the arc to the center of the circle is equal, the bottom end of the movable rod still abuts against the movable sheet to prevent it from moving when sliding on the arc surface. Only after the movable rod slides to the left side of the arc surface does the movable sheet begin to flip. On the other hand, a gap is provided between the outer edge of the movable sheet and the inner wall of the fourth through hole, that is, the air intake port of the air pump is the gap when the movable sheet is not flipped. Since the area of ​​the gap is small, the suction force is greatly increased, and the shape of the gap is annular, which can ensure the coverage area of ​​the suction force, thereby achieving the following effect: when the cutter cuts off the impurity rubber and is lifted up, The air pump has been adsorbing the impure rubber through the smaller annular gap, thereby greatly improving the suction force and ensuring that the impurity rubber does not fall off during the adsorption and lifting process. If the remaining rubber sheet is still connected to the impurity rubber, it will be blocked by the outer shell and completely separated until the movable rod slides to the left side of the arc surface. The movable sheet will then begin to flip over and the impurity rubber will be sucked into the box. This solution ensures that even if the long-term use of the equipment reduces the cutting accuracy and causes incomplete cutting, it will not affect production and processing. In order to protect the conveyor belt, the distance between the cutter and the conveyor belt when it reaches the lowest point can be reserved, and the equipment has a high fault tolerance rate.

[0042] like Figure 1The waste storage device 9 is arranged on the support frame 5, and the waste storage device 9 is connected to the first side hole 721 through a pipeline.

[0043] like Figure 1 The material storage trough is arranged on the ground at the rear end of the conveying device; the control system is electrically connected to the camera device and the electric screw mechanism 8 respectively.

[0044] like Figure 1 The camera device includes a scanning frame 1 and an identification camera 6. The scanning frame 1 is fixed on the ground. The scanning frame 1 is a frame structure with an illumination lamp arranged inside. A scanning camera is arranged on the inner wall of the top surface of the scanning frame 1. The light of the illumination lamp passes through the No. 1 conveyor belt 2 and the rubber sheet, and then the image is collected by the scanning camera; the identification camera 6 is arranged on the front side of the support frame 5. The identification camera 6 is used to finally identify the rubber sheet to be processed and compare it with the data obtained by the scanning camera, so as to confirm the number of the rubber sheet, as well as the position and posture of the rubber sheet, so as to avoid the movement and tilt of the rubber sheet during the transmission process, which may cause errors in the subsequent impurity removal position.

[0045] like Figure 1 The conveying device includes a No. 1 conveyor belt 2 and a No. 2 conveyor belt 3. The No. 1 conveyor belt 2 is made of transparent material to facilitate the passage of lighting. The rear end of the No. 1 conveyor belt 2 passes through the scanning frame 1; the front end of the No. 2 conveyor belt 3 is close to the rear end of the No. 1 conveyor belt 2, and a support platform 31 is arranged between the upper and lower belt surfaces of the No. 2 conveyor belt 3, and the support platform 31 is fixed on the ground.

[0046] like Figure 1 , Figure 5 The waste storage device 9 includes a box body 91, a No. 3 side hole 92, a transmission hose 93, a No. 4 side hole 94, a fence 95, an air pump 96, a three-way valve 97 and a baffle 98; the box body 91 is fixed on the support frame 5, and a ventilation hole is arranged on the top surface of the box body 91; the No. 3 side hole 92 is arranged on the top of the front side of the box body 91; the two ends of the transmission hose 93 are respectively connected to the No. 1 side hole 721 and the No. 3 side hole 92; the No. 4 side hole 94 is arranged at the bottom of the rear side of the box body 91; the fence 95 is arranged obliquely on the inner wall of the box body 91 The isolation fence 95 is located between the ventilation hole and the inner cavity of the box body 91, and is used to push the rubber sheet impurities down and drop them to the bottom of the box body 91; the air pump 96 is installed on the top surface of the box body 91; the three-way valve 97 is arranged on the top surface of the box body 91, and the three-way valve 97 is connected with the air pump 96, the ventilation hole and the ambient air respectively. The air pump 96 draws out the air in the box body 91 through the three-way valve 97 and discharges it to the outside air; the baffle 98 is hinged on the rear outer wall of the box body 91 and covers the outside of the fourth side hole 94. The stored rubber sheet impurities can be taken out by opening the baffle 98.

[0047] like Figure 5 The motor is a stepper motor, and the three-way valve 97 is an electromagnetic three-way valve. The motor and the three-way valve 97 are both electrically connected to the control system. The position of the inner shell 73 at this time can be calculated by calculating the number of motor steps, thereby determining the position of the cutter at this time. The control system regulates the opening and closing of the valve in the three-way valve 97, so that the suction force on the rubber sheet under the cutter is suspended when the cutter cuts downward, and the suction force on the rubber sheet is restored when the cutter rises, thereby avoiding unnecessary suction causing the rubber sheet to move and thus mispositioning the impurities thereafter.

[0048] like Figure 4 The cross-sections of the outer shell 72 and the inner shell 73 are both square, and the cutter 79 is in a square frame shape. The rubber hole cut by the square cutter 79 is also square. When cutting impurities of a larger area, the square cut is easier to calculate the punching path and the overlapping area of ​​the cut is small. In addition, even a metal conveyor belt will be deformed and uneven after long-term use. Therefore, in order to avoid the cutter from contacting with the conveyor belt and damaging the conveyor belt, and to avoid the conveyor belt from being uneven after long-term use, and to improve the fault tolerance of production and processing, a gap will be left between the cutter and the conveyor belt when it moves to the lowest point, and the impurities of the rubber sheet that are not completely cut off rely on the suction of the air pump and the lifting of the inner shell to completely separate them from the rubber sheet.

[0049] When the natural rubber sheet batch impurity removal processing equipment in this embodiment is in operation, the rubber sheet 4 passes through the scanning frame 1, and the light of the lighting lamp passes through the No. 1 conveyor belt 2 and the rubber sheet, and then the image is collected by the scanning camera, and the image signal is transmitted to the control system, the control system numbers the rubber sheet, and analyzes the position and size of the impurities on the rubber sheet to generate a corresponding impurity removal scheme; the rubber sheet is transported from the No. 1 conveyor belt 2 to the No. 2 conveyor belt 3, and when it is transmitted to the vicinity of the impurity removal device, the recognition camera 6 collects the image of the rubber sheet on the No. 2 conveyor belt 3, and the image signal is transmitted to the control system, the control system compares and identifies the number of the rubber sheet to prepare to load the previously generated impurity removal scheme, and adjusts the angle and position of the impurity removal scheme as a whole according to the actual position and posture of the rubber sheet at this time, and then the rubber sheet enters under the impurity removal device 7, and the control system controls the electric screw mechanism 8 according to the previously generated impurity removal scheme to make the impurity removal device 7 stop at the impurity position in turn to remove the impurities, and the impurity-free rubber sheet follows the No. 2 conveyor belt 3 and falls into the storage tank. During the operation of the impurity removal device 7, the motor drives the inner shell 73 downward through the crank rocker mechanism, so that the cutter 79 cuts off the impurity part. During this process, the reed 78 pushes the movable rod 77 to move its bottom to the right, pushing the movable sheet 74 to flip downward; then the motor drives the inner shell 73 upward again, and at the same time, due to the work of the air pump 96, air is sucked from the gap at the outer edge of the movable sheet 74, and the impurity rubber is tightly adsorbed and lifted up. During the lifting process, due to the obstruction of the outer shell 72, the bond between the impurity and the original rubber sheet is broken. When the impurity rubber is lifted to nearly the highest point, the movable rod 77 moves to the far left, the movable sheet 74 flips over, and the impurity rubber is sucked into the box body 91 through the No. 2 side hole 731, the No. 1 side hole 721 and the transmission hose 93 for storage.

[0050] It should be understood that the above are only preferred embodiments of the present invention, and the patent scope of the present invention cannot be limited thereto. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
