Description

Technical Field

[0001] The present application relates to the technical field of rubber production and processing devices, and particularly to a rubber strip sorting device. Background Art

[0002] In the field of rubber manufacturing, there is a rubber molding method called injection vulcanization molding. In this molding method, the refined rubber compound needs to be cut into long strips in advance, and then the long strip rubber compound is injected into the molding die by heating and extrusion to carry out vulcanization molding.

[0003] After the rubber raw material is made into sheets by rubber mixing, it mostly needs to be trimmed and cut to a fixed length by a rubber strip cutting machine. After cutting, the rubber strips fall onto the conveyor belt. Inevitably, the ends of two adjacent rubber strips are uneven. Therefore, it is necessary to sort and align the rubber strips so that the rubber strips are parallel to each other and the ends are aligned, so as to facilitate the subsequent neat insertion and placement of the rubber strips, ensure that the rubber strips placed in the vulcanizer die are neat, and improve the quality of rubber products processed by the vulcanizer.

[0004] In view of the above related technologies, in rubber manufacturing enterprises with manual production, the sorting of rubber strips mostly relies on manual labor to place them into a fixed template and then place them on the vulcanizer die, resulting in a relatively high labor intensity for workers. In some rubber manufacturing enterprises with automated production, after the rubber strips are inserted and placed into the vulcanizer die, they are uneven or skewed left and right, seriously affecting the uniformity of vulcanization. Therefore, improvement is needed. Summary of the Utility Model

[0005] In order to facilitate the sorting of rubber strips and prepare for the subsequent processing of rubber strips, the present application provides a rubber strip sorting device.

[0006] The rubber strip sorting device provided by the present application adopts the following technical solutions:

[0007] A rubber strip sorting device includes a frame, a conveyor belt, an end sorting mechanism, and two-side synchronous sorting mechanisms. The conveyor belt is rotatably connected to the frame and is used for conveying the cut rubber strips. The end sorting mechanism is arranged on the frame and is located on the conveying path of the conveyor belt. The end sorting mechanism is used for sorting the ends of the rubber strips on the conveyor belt. The two-side synchronous sorting mechanisms are used for straightening the single rubber strips horizontally after the ends are sorted neatly.

[0008] The end sorting mechanism includes a first driving member, a first positioning plate, a second driving member, and a second positioning plate. The first positioning plate and the second positioning plate are arranged horizontally opposite to each other. The first driving member is connected to the first positioning plate and is used to control the movement of the first positioning plate. The second driving member is connected to the second positioning plate and is used to control the movement of the second positioning plate.

[0009] The moving directions of the first positioning plate and the second positioning plate are on the same straight line, and both the first positioning plate and the second positioning plate are used to push the rubber strip on the conveyor belt.

[0010] By adopting the above technical solution, when the first driving member and the second driving member are in the retracted state, the horizontal distance between the first positioning plate and the second positioning plate is adjusted to be slightly wider than the length of a single rubber strip. During production, the rubber strip cut by the rubber strip cutting machine falls onto the conveyor belt, and the conveyor belt drives the rubber strip to move in the direction close to the end material arranging mechanism.

[0011] In the initial state, the piston rods of the first driving member and the second driving member are in the extended state. When the rubber strip passes through, the piston rods of the first driving member and the second driving member retract to align the ends of the rubber strip. After the positions of both ends of the rubber strip are adjusted, the two-side synchronous material arranging mechanism can be used to further straighten a single rubber strip, making the rubber strip straighter and the rubber strips parallel to each other. The entire production process facilitates the arrangement of the rubber strips and prepares for the subsequent processing of the rubber strips.

[0012] Preferably, the first driving member and the second driving member are cylinders, oil cylinders or electric push rods.

[0013] By adopting the above technical solution, cylinders, oil cylinders or electric push rods can all be used to control the horizontal linear movement of the first positioning plate and the second positioning plate.

[0014] Preferably, the two-side synchronous material arranging mechanism includes a sliding seat, a sliding rail and a top plate. The sliding seat is connected to the frame, the sliding rail is arranged on the sliding seat in a lifting manner, the top plate is connected to the sliding rail and is located above the conveyor belt, and the top plate is used to synchronously hold the rubber strip that retreats on the conveyor belt on both sides.

[0015] By adopting the above technical solution, after the positions of both ends of the rubber strip are adjusted, the conveyor belt first conveys the rubber strip to a position beyond the top plate; then the sliding rail moves along the sliding seat, making the top plate gradually approach the conveyor belt; then the conveyor belt starts to reverse, and the rubber strip will gradually approach the top plate. Since the position of the top plate is fixed relative to the conveyor belt, the top plate will exert a holding effect on the rubber strip, thereby realizing the arrangement of the rubber strip.

[0016] Preferably, it further includes a third driving member and a connecting shell. The connecting shell is used to connect the sliding rail and the top plate, and the third driving member is connected to the connecting shell and is used to control the lifting of the top plate.

[0017] By adopting the above technical solution, the third driving member controls the movement of the connecting shell, and further drives the top plate to move up and down.

[0018] Preferably, it further includes a rack, a gear and a rotating rod. The third driving member is a pneumatic cylinder. The rack is connected to both the piston rod of the pneumatic cylinder and the connecting shell. The gear meshes with the rack, and the rotating rod is rotatably connected to the gears on both sides, so that the racks and the gears on both sides achieve synchronous movement.

[0019] By adopting the above technical solution, when the piston rod of the pneumatic cylinder extends, the top plate can move along the direction close to the conveying surface of the conveyor belt. At the same time, the movement of the rack can drive the gear to rotate, and then drive the rotating rod to rotate. The rotation of the rotating rod can drive the racks and gears on both sides to achieve synchronous movement.

[0020] Preferably, it further includes a guide rod and an adjustment seat. The guide rod is connected to the frame, and the adjustment seat is adjustably arranged on the guide rod and there are two spaced apart. The first driving member and the second driving member are respectively connected to the two adjustment seats.

[0021] By adopting the above technical solution, the two adjustment seats can move on the guide rod, so that the staff can adjust the distance between the two adjustment seats according to actual needs, and then change the distance between the first positioning plate and the second positioning plate, which is convenient for finishing the ends of rubber strips with different lengths and improves the practicability.

[0022] Preferably, it further includes a first screw rod and a second screw rod. The first screw rod and the second screw rod are on the same straight line and are both rotatably connected to the frame; the two adjustment seats are respectively slidably connected to the first screw rod and the second screw rod, and adjustment handwheels are provided at the ends of the first screw rod and the second screw rod.

[0023] By adopting the above technical solution, the staff can control the rotation of the first screw rod and the second screw rod by controlling the adjustment handwheel, convert the rotation into the linear motion of the adjustment seat, so as to change the horizontal distance between the two adjustment seats to adapt to rubber strips of different lengths.

[0024] Preferably, the conveyor belt is made of anti-sticking material.

[0025] By adopting the above technical solution, since the rubber strip needs to move during the finishing process, the rubber strip will have sliding friction with the conveyor belt. The conveyor belt made of anti-sticking or patterned material can reduce the friction coefficient and reduce the sliding friction force when the rubber strip moves.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] (1) By setting the end trimming mechanism, the end trimming mechanism can trim the ends of the rubber strip, ensure the neatness of the positions of both ends of the rubber strip, and the whole process is automated, reducing the labor intensity of personnel.

[0028] (2) By setting up the two-side synchronous material arranging mechanism, the rubber strip can be further straightened, making the rubber strip straighter.

[0029] (3) By setting up the guide rod and the adjusting seat, the staff can adjust the distance between the two adjusting seats according to actual needs, thereby changing the distance between the first positioning plate and the second positioning plate, facilitating the arrangement of the ends of rubber strips of different lengths, and having a wider range of applications.

For example, it can be a fixed connection; it can also be a detachable connection; or integrated; it can also be a mechanical connection. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of this application can be understood according to specific circumstances.

[0040] The following will describe in detail some embodiments of this application with reference to the drawings. Without conflict, those skilled in the art can combine and combine the different embodiments or examples and the features of different embodiments or examples represented in this application.

[0041] The embodiments of this application disclose a rubber strip feeding device. Referring to Figure 1 and Figure 2 , the feeding device includes a frame 1, a conveyor belt 2, an end feeding mechanism 3 and two-side synchronous feeding mechanisms 6. The frame 1 serves as a support carrier and is fixedly installed on the ground. The conveyor belt 2 is rotatably connected to the frame 1, and the conveyor belt 2 is used to convey the cut rubber strips. The end feeding mechanism 3 is installed on the frame 1 and is located on the conveying path of the conveyor belt 2. The end feeding mechanism 3 is used to tidy up the ends of the rubber strips on the conveyor belt 2. The two-side synchronous feeding mechanisms 6 are installed on the frame 1 and are used to straighten the tidied-up rubber strips laterally one by one, making the rubber strips straighter and parallel to each other.

[0042] Specifically, the end material sorting mechanism 3 includes a first driving member 31, a first positioning plate 32, a second driving member 33 and a second positioning plate 34, and the first positioning plate 32 and the second positioning plate 34 are arranged horizontally opposite to each other. The first driving member 31 is connected to the first positioning plate 32, and is used to control the horizontal linear movement of the first positioning plate 32, and the moving direction of the first positioning plate 32 is perpendicular to the conveying direction of the conveyor belt 2. The second driving member 33 is connected to the second positioning plate 34, and is used to control the horizontal movement of the second positioning plate 34, and the moving directions of the first positioning plate 32 and the second positioning plate 34 are on the same straight line, and the first positioning plate 32 and the second positioning plate 34 are both used to push the rubber strip on the conveyor belt 2. The first driving member 31 and the second driving member 33 can be but are not limited to a cylinder, an oil cylinder or an electric push rod. In this embodiment, the first driving member 31 and the second driving member 33 are both cylinders.

[0043] By adjusting the horizontal spacing between the first positioning plate 32 and the second positioning plate 34 to be slightly wider than the length of a single rubber strip in advance when the first driving member 31 and the second driving member 33 are retracted, during production, the rubber strips cut by the rubber strip cutting machine fall onto the conveyor belt 2, and the conveyor belt 2 moves with the rubber strips in the direction close to the end material sorting mechanism 3.

[0044] In the initial state, the piston rods of the first driving member 31 and the second driving member 33 are extended. When the rubber strip passes, the piston rods of the first driving member 31 and the second driving member 33 are retracted to align the ends of the rubber strip. After the positions of the two ends of the rubber strip are adjusted, the synchronous material sorting mechanism 6 on both sides can be used to further straighten the single rubber strip, so that the rubber strip is straighter and each rubber strip is parallel to each other. The entire production process makes it easy to sort the rubber strip and prepare for subsequent processing of the rubber strip.

[0045] In this embodiment, the conveyor belt 2 is made of anti-sticking material, including but not limited to Teflon, PU polyurethane and PVC. Since the rubber strip needs to move during the sorting process, the rubber strip will slide against the conveyor belt 2. The conveyor belt 2 made of anti-sticking material can reduce the friction coefficient and reduce the sliding friction when the rubber strip moves.

[0046] Combination Figure 3, wherein, in some embodiments, a guide rod 4 is also fixedly installed on the frame 1. The guide rod 4 is located above the conveyor belt 2 and is arranged along the moving direction of the first positioning plate 32. Two adjusting seats 5 are also installed on the guide rod 4. The two adjusting seats 5 are spaced apart and are both movably arranged on the guide rod 4. The first driving member 31 and the second driving member 33 are respectively installed on the two adjusting seats 5. Specifically, a first screw rod 12 and a second screw rod 13 are rotatably connected to the frame 1. The first screw rod 12 and the second screw rod 13 are on the same straight line, and the first screw rod 12 is parallel to the guide rod 4. The two adjusting seats 5 are respectively slidably connected to the first screw rod 12 and the second screw rod 13. The ends of the first screw rod 12 and the second screw rod 13 are both fixedly connected with adjusting handwheels 14, and the adjusting handwheels 14 are used to control the rotation of the first screw rod 12 and the second screw rod 13.

[0047] The staff can control the rotation of the first screw rod 12 and the second screw rod 13 by controlling the adjusting handwheels 14, convert the rotation into the linear motion of the adjusting seats 5, so as to change the horizontal distance between the two adjusting seats 5, which is convenient for the staff to adjust the distance between the two adjusting seats 5 according to actual needs, and further change the distance between the first positioning plate 32 and the second positioning plate 34, which is convenient for finishing the ends of rubber strips with different lengths, and the applicable range is wider.

[0048] Combined with Figure 4 and Figure 5 , the two-side synchronous material arranging mechanism 6 includes a sliding seat 61, a sliding rail 62 and a top plate 63. The sliding seat 61 is installed on the frame 1, and the sliding rail 62 is arranged to be lifted and lowered on the sliding seat 61. The top plate 63 is connected to the sliding rail 62 and is located above the conveyor belt 2. The top plate 63 is used to synchronously hold the rubber strip that retreats on the conveyor belt 2 on both sides.

[0049] After the positions of both ends of the rubber strip are adjusted, the conveyor belt 2 first conveys the rubber strip to a position beyond the top plate 63; then the sliding rail 62 moves along the sliding seat 61, so that the top plate 63 gradually approaches the conveyor belt 2; then the conveyor belt 2 starts to convey in the reverse direction. At this time, the rubber strip will gradually approach the top plate 63. Since the position of the top plate 63 is fixed relative to the conveyor belt 2, the top plate 63 will exert a holding force on the rubber strip, causing the rubber strip to move on the conveyor belt 2, so as to realize the arrangement of the rubber strip.

[0050] In this embodiment, the slide rail 62 and the top plate 63 are connected together through a connecting shell 7. A third driving member 8 is also installed on the frame 1. The third driving member 8 is a pneumatic cylinder and is connected to the connecting shell 7. The third driving member 8 is used to control the lifting of the top plate 63. Among them, a rack 9 is further connected to the piston rod of the pneumatic cylinder, and the rack 9 connects the pneumatic cylinder and the connecting shell 7. A gear 10 and a rotating rod 11 are also installed on the frame 1. The gear 10 is meshed with the rack 9; the rotating rod 11 is rotatably connected to the gears 10 on both sides. The rotation axis of the rotating rod 11 is parallel to the length direction of the guide rod 4, so that the racks 9 and the gears 10 on both sides can achieve synchronous movement.

[0051] When the piston rod of the pneumatic cylinder extends, the top plate 63 can move in the direction close to the conveying surface of the conveyor belt 2. At the same time, the movement of the rack 9 can drive the gear 10 to rotate, and then drive the rotating rod 11 to rotate. The rotation of the rotating rod 11 can drive the racks 9 and the gears 10 on both sides to achieve synchronous movement.

[0052] The implementation principle of a rubber strip feeding device according to an embodiment of the present application is as follows: By adjusting the horizontal distance between the first positioning plate 32 and the second positioning plate 34 to be slightly wider than the length of a single rubber strip in a state where the first driving member 31 and the second driving member 33 are in a retracted state in advance. During production, the rubber strips cut by the rubber strip cutting machine fall onto the conveyor belt 2, and the conveyor belt 2 drives the rubber strips to move in the direction close to the end feeding mechanism 3.

[0053] When the rubber strip passes through the first positioning plate 32 and the second positioning plate 34, the end feeding mechanism 3 sorts out the ends of the rubber strip to ensure the neatness of the positions of both ends of the rubber strip. The rubber strip after end sorting continues to be conveyed, and then the synchronous feeding mechanisms 6 on both sides further straighten the rubber strip to make the rubber strip straighter. The entire feeding process is automated, reducing the labor intensity of personnel.

[0054] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
