Description

Technical Field

[0001] This utility model relates to the field of open mixing mill technology, specifically an automatic triangular-bundle rubber open mixing mill. Background Technology

[0002] A rubber mixing mill is used to mix and plasticize uniformly blended raw materials, providing a homogeneous molten material for subsequent processing. The main working components are two counter-rotating hollow or perforated rollers. During operation, the rollers rotate at different speeds relative to each other, causing the raw rubber or rubber compound to undergo strong shearing action to achieve plasticizing or mixing. Triangular bale packaging is an important operation in the rubber mixing process, effectively mixing the rubber and additives. The initial triangular bale operation involves feeding the rubber compound between the rollers, and then packaging the compound... After loading the rubber onto the front roller, you can directly collect the rubber head below the front roller by hand, or use a rubber cutter to cut the rubber material wrapped on the front roller horizontally before collecting it. Fold the rubber material, and then use both hands to press the collected rubber material back onto the roller, folding it at an angle of about 45 degrees to the roller axis to form a triangle. Alternatively, you can first beat the rubber material into a ball before folding it into a triangle. In the current rubber open mill, triangular packaging is generally done manually during packaging, which is time-consuming and labor-intensive. Automatic packaging equipment can only rewind and cannot package triangular bags.

[0003] Chinese patent CN218985356U discloses an open mill with automatic material turning function, including a support frame. The support frame is rotatably connected to a front roller and a rear roller. Lifting rods are slidably connected to both ends of the front roller in the vertical direction. The support frame is provided with two sets of lifting components that adjust the position of the two lifting rods in the vertical direction. A guide rod is fixedly connected between the two lifting rods. A movable block is slidably connected to the guide rod along the axial direction of the front roller. A translation component for driving the movable block to slide is provided between the two lifting rods. A mounting plate is fixedly connected to the movable block. Two baffles are spaced apart along the axial direction of the front roller on the mounting plate. Rubber scrapers are detachably connected to the baffles and abut against the circumference of the front roller.

[0029] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0030] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-7 An automatic triangular-bundle rubber open mixing mill includes a frame 1, and further includes: a rubber mixing device 2, a material cutting device 3, a multi-directional drive device 4, and a clamping device 5. The rubber mixing device 2 is mounted on the frame 1, the material cutting device 3 is mounted on the front side of the middle part of the rubber mixing device 2, the multi-directional drive device 4 is mounted on the front side of the upper part of the rubber mixing device 2, and the clamping device 5 is mounted on the multi-directional drive device 4. The clamping device 5 includes: an extension plate 51, a linear guide rail 52, a first slider 53, a limiting plate 54, and a T-shaped bracket 55. The extension plate 51 is fixedly mounted on the multi-directional drive device 4, the linear guide rail 52 is fixedly mounted on the upper side of the extension plate 51, the first slider 53 is slidably connected to the linear guide rail 52, the two limiting plates 54 are fixedly mounted at the front and rear ends of the linear guide rail 52, and the T-shaped bracket 55 is fixedly mounted on the upper side of the first slider 53. The clamping device 5 also includes: a sliding contact mechanism, which is mounted on the T-shaped bracket 55.

[0031] The rubber mixing device 2 mixes the raw materials, the cutting device 3 cuts the raw materials being mixed, the clamping device 5 clamps the cut end of the rubber strip, and the multi-directional drive device 4 drives the clamping device 5 in multiple directions to achieve the packaging of the rubber strip in triangular packages.

[0032] The linear guide rail 52 has tension springs 56 fixedly installed on both sides of the limiting plate 54 on the rear side. The other end of the tension spring 56 is fixedly connected to the end of the T-shaped bracket 55 near the first slider 53.

[0033] like Figure 2 and Figure 3 As shown, the clamping device 5 moves towards the cutting edge of the adhesive strip, and the sliding contact mechanism of the clamping device 5 is in close contact with the cutting edge of the adhesive strip. The clamping device 5 continues to move towards the cutting edge of the adhesive strip, causing the T-shaped bracket 55 to move away from the cutting edge of the adhesive strip. The movement of the T-shaped bracket 55 away from the cutting edge of the adhesive strip drives the first slider 53 to move away from the cutting edge of the adhesive strip, causing the tension spring 56 to undergo elastic deformation. This facilitates the sliding contact mechanism to squeeze and contact the adhesive strip in the front-back direction, thereby improving the clamping success rate.

[0034] The multi-directional driving device 4 includes an arc-shaped driving mechanism. Two arc-shaped driving mechanisms are installed on the left and right sides of the frame 1. Each arc-shaped driving mechanism includes an arc-shaped plate 41, an arc-shaped guide rail 42, a second slider 43, a rack 44, a moving bracket 45, a self-locking motor 46, and a first gear 47.

The first gear 47 is fixedly connected to the output shaft of the self-locking motor 46. The first gear 47 and the rack 44 mesh with each other.

[0035] like Figure 4 and Figure 5 As shown, the output shaft of the self-locking motor 46 of the arc-shaped drive mechanism of the multi-directional drive device 4 rotates, driving the first gear 47 to rotate. The first gear 47 moves along the direction of the rack 44 under the restriction of the rack 44, so that the self-locking motor 46, the first gear 47, the moving bracket 45 and the second slider 43 move along the direction of the rack 44, which is beneficial for the moving bracket 45 to move in an arc-shaped trajectory.

[0036] The multi-directional driving device 4 further includes a lateral driving mechanism, which is mounted on a movable bracket 45. The lateral driving mechanism includes a first linear module 48 and a second linear module 49. The first linear module 48 is fixedly mounted on the movable bracket 45, and the second linear module 49 is fixedly mounted on the output end of the first linear module 48.

[0037] The movable bracket 45 moves along the rack 44, causing the first linear module 48 and the second linear module 49 to move along the rack 44. The output end of the first linear module 48 of the transverse drive mechanism moves left and right, causing the second linear module 49 to move left and right. The output end of the second linear module 49 moves back and forth, which is beneficial to realize the multi-directional drive clamping device 5.

[0038] The lateral drive mechanism further includes: a fixed bracket 410, a rotary cylinder 411, and a pneumatic gripper 412.

The pneumatic gripper 412 is fixedly installed on the output end of the rotary cylinder 411 through the bracket. The extension plate 51 is fixedly installed on the gripping finger on the upper side of the pneumatic gripper 412.

[0039] The rotation of the output end of the rotary cylinder 411 drives the pneumatic gripper 412 to rotate, which can quickly adjust the clamping angle of the pneumatic gripper 412, which is beneficial for clamping different rubber strips at different angles.

[0040] Example 2: In some embodiments, such as Figures 1-7 In a preferred embodiment of this utility model, the sliding contact mechanism includes: a sliding sleeve 59, a sliding rod 510, a sliding long plate 511, a spring 512, and a limiting plate 513.

[0041] like Figure 5 and Figure 6As shown, the clamping device 5 moves towards the cutting edge of the adhesive strip, and the sliding contact mechanism of the clamping device 5 is in close contact with the cutting edge of the adhesive strip. The clamping device 5 continues to move towards the cutting edge of the adhesive strip, causing the T-shaped bracket 55 to move away from the cutting edge of the adhesive strip. The movement of the T-shaped bracket 55 away from the cutting edge of the adhesive strip drives the first slider 53 to move away from the cutting edge of the adhesive strip, causing the tension spring 56 to undergo elastic deformation. The sliding contact mechanism squeezes and contacts the adhesive strip in the front-back direction, improving the clamping success rate. The sliding plate 511 of the sliding contact mechanism moves up and down towards the adhesive strip, and the spring 512 undergoes elastic deformation, which is beneficial for the sliding contact mechanism to squeeze and contact the adhesive strip in the front-back direction and the up and down direction, improving the clamping success rate.

[0042] The clamping device 5 further includes a clamping plate mechanism, which is installed on the gripping fingers on the lower side of the pneumatic gripper 412. The clamping plate mechanism includes a vertical rod 57 and a fixed long plate 58. The vertical rod 57 is fixedly installed on the gripping fingers on the lower side of the pneumatic gripper 412, and the fixed long plate 58 is fixedly installed at the end of the vertical rod 57 away from the pneumatic gripper 412.

[0043] The fixed long plate 58 is placed close to the bottom of the adhesive strip, and the lower side of the adhesive strip cut is cut. The vertical rod 57 is used to extend the fixed long plate 58.

[0044] The rubber mixing device 2 includes: a rubber mixing roller 21, a second gear 22, and a drive motor 23.

The drive motor 23 is fixedly installed on the right side of the frame 1 via a motor bracket, and the rotating shaft of one of the rubber mixing rollers 21 is fixedly connected to the rotating shaft of the drive motor 23.

[0045] like Figure 2 and Figure 3 As shown, the output of the drive motor 23 of the rubber mixing device 2 rotates, causing one of the rubber mixing rollers 21 to rotate. The rotation of the rubber mixing roller 21 drives the second gear 22 to rotate. The rotation of the second gear 22 drives the shaft of the other rubber mixing roller 21 to rotate. The rotation of the shaft of the other rubber mixing roller 21 causes the two rubber mixing rollers 21 to rotate in opposite directions, so as to fully mix the colloid and raw materials.

[0046] The material cutting device 3 includes: a cylinder 31, a fixed rod 32, a sliding bracket 33, and a cutter head 34. The cylinder 31 is fixedly installed on the right side of the frame 1, the fixed rod 32 is fixedly installed on the middle side of the frame 1, the sliding bracket 33 is slidably connected to the fixed rod 32, the right side of the sliding bracket 33 is fixedly connected to the output end of the cylinder 31, and the cutter head 34 is fixedly installed on the upper side of the sliding bracket 33.

[0047] like Figure 1 , Figure 2 , Figure 3 and Figure 7 As shown, the output end of the cylinder 31 of the cutting device 3 extends, causing the sliding bracket 33 to move to the left. The sliding bracket 33 moves to the left, causing the cutter head 34 to move to the left, cutting the rubber strip being mixed horizontally so that it can be clamped in the next step.

[0048] like Figure 6 As shown, the fixed long plate 58 and sliding long plate 511 of the clamping device 5 abut against the arc surface of the rubber mixing roller 21. After clamping the right side of the cut rubber strip, the output end of the first linear module 48 moves to the left, driving the second linear module 49 and the clamping device 5 to move to the left. At the same time, the arc-shaped drive mechanism drives the first linear module 48, the second linear module 49 and the clamping device 5 to move downward. At this time, the trajectory of the right side of the rubber strip is to move to the lower left of the rubber strip. Then, the rubber strip is released, the upper left corner of the rubber strip is clamped, and the upper left corner of the rubber strip is moved to the lower right to continuously pack out triangular bags.
