Description

Technical Field

[0001] The present invention relates to the technical field of asphalt production, and particularly relates to an automatic feeding device for processing asphalt raw materials. Background Art

[0002] SBS modified asphalt is an excellent road material and is widely used in scenarios such as high-grade highways, bridges, airport runways, etc. With the continuous improvement of the requirements for material performance in road construction, the application of SBS modified asphalt has become more and more popular. SBS particles are usually packaged in bags, and the packaging bags are usually made of multi-layer composite materials, including a plastic inner bag and a woven outer bag, which can prevent moisture and dust, and have high strength, suitable for long-distance transportation and storage.

[0003] Existing SBS modified asphalt usually needs to be unloaded from the packaging bag and put into the feeding equipment. Since the bagged materials are usually heavy, the traditional manual handling and bag-opening methods not only consume physical strength but may also cause worker fatigue, thus affecting production efficiency. Moreover, problems such as dust and material scattering may occur during the manual bag-opening and feeding processes, posing safety hazards and risks to personal health. Summary of the Invention

An inverted T-shaped mounting frame 51 is jointly installed between the inner wall of the right end of the C-shaped support frame 1 and the vertical plate 49. A second circular blade 52 is rotatably installed through the upper end of the vertical section of the inverted T-shaped mounting frame 51. The first circular blade 47 and the second circular blade 52 are arranged to be in movable contact with each other front and back. A rectangular mounting groove 53 is formed at the position corresponding to the second circular blade 52 in the inverted T-shaped mounting frame 51. A second connecting shaft 54 is fixedly installed in the middle of the second circular blade 52. One end of the second connecting shaft 54 away from the second circular blade 52 is rotatably connected to the front inner wall of the rectangular mounting groove 53.

The rear end of the third connecting shaft 56 rotates through the inverted T-shaped mounting frame 51 and is rotatably connected to the rear inner wall of the rectangular mounting groove 53. The second connecting shaft 54 and the third connecting shaft 56 are connected by a transmission belt.

[0041] During the process of the conveyor belt 22 transporting the bagged SBS to the front and rear U-shaped support plates 344, the circular blade 1 47 will drive the front and rear annular mounting seats 44 to slide upward along the corresponding kidney-shaped through holes 43 respectively through the connecting shaft 1 46 for adaptive compensation. During this process, the second motor 48 is used to control the connecting shaft 1 46 to drive the circular blade 1 47 to rotate. At the same time, the third motor 55 is used to control the connecting shaft 3 56 to rotate. The connecting shaft 3 56 drives the connecting shaft 2 54 to rotate through belt drive. The connecting shaft 2 54 drives the circular blade 2 52 to rotate. The circular blade 1 47 and the circular blade 2 52 jointly cut the middle part of the bagged SBS. During the movement of the bagged SBS from left to right, due to the different thicknesses of the bagged SBS, under the action of the spring telescopic rod 45, the circular blade 1 47 will drive the front and rear annular mounting seats 44 to slide gradually downward along the corresponding kidney-shaped through holes 43 through the connecting shaft 1 46 until the bagged SBS is cut into two parts.

[0045] Refer to Figure 2 and Figure 4, the transmission part 67 includes bearing seats two 678 rotatably sleeved on both the left and right sides of the front and rear transmission shafts one 64. A plurality of bearing seats two 678 are fixedly connected to the C-shaped support frame 1. Passive gears two 671 are installed at the right ends of the front and rear transmission shafts one 64. Passive gears two 671 are also provided above the front and rear passive gears two 671. The two passive gears two 671 distributed vertically are meshed with each other. A transmission shaft three 672 is installed at the left end of the upper passive gear two 671. The transmission shaft three 672 is rotatably installed on the C-shaped support frame 1 through a bearing seat three 679. The transmission shaft one 64 and the left transmission shaft two 65 are connected by a transmission belt. The transmission shaft three 672 and the right transmission shaft two 65 are connected by a transmission belt. A driving gear 673 is rotatably installed in the middle of the right end of the C-shaped support frame 1.

The two lower front and rear passive gears two 671 are respectively meshed with the corresponding incomplete gears two 675. Rotating shafts two 676 are installed at the right ends of the front and rear incomplete gears two 675, the driving gear 673, and the transmission gear two 674. The rotating shafts two 676 corresponding to the front incomplete gear two 675 and the transmission gear two 674 are connected by a transmission belt. The rotating shafts two 676 corresponding to the rear incomplete gear two 675 and the driving gear 673 are connected by a transmission belt. A forward and reverse motor two 677 is installed in the middle of the right end of the C-shaped support frame 1 through a motor seat. The output shaft of the forward and reverse motor two 677 is fixedly connected to the rotating shaft two 676 of the driving gear 673.

[0046] After the circular blade one 47 and the circular blade two 52 jointly complete the cutting of the middle part of the bagged SBS, it should be noted that the notch of the C-shaped support plate 344 plays an avoidance role for the multiple claw hooks 632. The two claw hooks 632 on the front and rear sides are initially in an open state where they are far away from each other. First, the positive and reverse motor two 677 is used to control the connected rotating shaft two 676 to drive the driving gear 673 to rotate. The driving gear 673 meshes with the transmission gear two 674 for transmission, and then drives the front incomplete gear two 675 and the rear incomplete gear two 675 to rotate synchronously through a belt drive. At this time, the front and rear two incomplete gears two 675 rotate in the same direction but in opposite directions. The front and rear two incomplete gears two 675 are respectively in transmission with the corresponding driven gears two 671, driving the front and rear two transmission shafts one 64 to rotate synchronously by 60 degrees. The lower front and rear two driven gears two 671 are respectively in transmission with the upper front and rear two driven gears two 671, driving the front and rear two transmission shafts three 672 to rotate synchronously by 60 degrees. The front and rear two transmission shafts one 64 respectively drive the corresponding transmission shafts two 65 on the left side to rotate synchronously by 60 degrees through a belt drive. The front and rear two transmission shafts three 672 respectively drive the corresponding transmission shafts two 65 on the right side to rotate synchronously by 60 degrees through a belt drive. That is, the left and right two transmission shafts two 65 on the same side rotate in opposite directions by the same angle. The left and right two transmission shafts two 65 respectively mesh with the left and right two incomplete tooth rings 631 through the corresponding transmission tooth rings 665, driving the corresponding left and right two claw hooks 632 to rotate by 60 degrees around the support shaft 62 until the two claw hooks 632 on the same side approach each other and become in a cross-clamping state. At this time, the left and right two claw hooks 632 on the front and rear sides both pierce the bagged SBS and jointly perform the clamping work on the bagged SBS.

[0047] It should be noted that during this period, the rotation directions of the front and rear two transmission shafts one 64, the two transmission shafts two 65 and the transmission shaft three 672 are all opposite, so that the upper and lower two claw hooks 632 on the front and rear sides perform the clamping or opening work synchronously. The conveying mechanism 2, the material blocking and supporting mechanism 3 and the clamping and limiting mechanism 6 cooperate to use multiple claw hooks 632 to jointly perform the piercing and clamping work on the bagged SBS conveyed to the front and rear two C-shaped support plates 344. The clamping is stable and the problem of the bagged SBS falling off is avoided.

[0048] When all four claw hooks 632 penetrate the bagged SBS, the forward and reverse motors three 350 control the rotation of the connected lead screws 349 respectively. The front and rear lead screws 349 drive the other lead screw 349 to rotate synchronously through belt transmission respectively. The left and right lead screws 349 on the front and rear sides drive the corresponding L-shaped connecting plates 342 and rectangular connecting plates 343 to move downward respectively. The two front and rear L-shaped connecting plates 342 jointly drive the baffle plate 32 to move downward in the two front and rear rectangular sliding holes one 31. The baffle plate 32 is movably attached to the position of the conveyor belt 22. The two front and rear rectangular connecting plates 343 drive the corresponding support sliding plates 341 to slide downward along the corresponding rectangular sliding holes two 33 to the bottom side position in the rectangular sliding holes two 33 respectively. The multiple support sliding plates 341 drive the corresponding sliding seats 346 to move downward through the corresponding support connecting rods 347 respectively. During this period, the multiple sliding seats 346 will all make adaptive sliding compensation along the corresponding installation sliding grooves 345. At this time, the two front and rear C-shaped support plates 344 will rotate around the hinge points and become in a downward inclined state respectively. After the bagged SBS is cut into two parts, the SBS particles in the bagged SBS will also fall downward and be received by the externally provided material receiving device. The baffle support mechanism 3, the clamping and limiting mechanism 6 and the opposite cutting mechanism 4 cooperate to control the baffle plate 32 to descend for shielding while controlling the two front and rear C-shaped support plates 344 to change from the horizontal support state to the downward inclined state, so as to achieve the effect of automatically discharging the SBS particles in the bagged SBS, effectively avoiding the direct contact between workers and materials, and reducing potential safety hazards and health risks.

[0049] It should be noted that before the SBS particles fall, the four claw hooks 632 pierce and fix the cut-in-half packaging bag to prevent the packaging bag from falling together with the SBS particles.

[0050] Refer to Figure 2 、 Figure 4 and Figure 5 As shown in, the flipping mechanism 7 includes a driven gear one 71 rotatably installed at the position corresponding to the rear support shaft 62 at the right end of the C-shaped support frame 1. The driven gear one 71 is fixedly sleeved on the corresponding support shaft 62. A forward and reverse motor one 72 is installed at the rear side of the right end of the C-shaped support frame 1 through a motor base. The output shaft of the forward and reverse motor one 72 is fixedly connected with the forward and reverse motor one 72. A transmission gear one 74 is rotatably installed at the position in front of the driven gear one 71 at the right end of the C-shaped support frame 1. A rotating shaft one 75 is installed at the right end of the transmission gear one 74. The transmission gear one 74 and the incomplete gear one 73 are respectively meshed with the driven gear one 71, and the front support shaft 62 and the rotating shaft one 75 are connected by a transmission belt.

[0051] The forward and reverse rotation of motor 1 - 72 drives the rotation of the incomplete gear 1 - 73, thereby engaging the rotation of the passive gear 1 - 71. The front and rear support shafts 62 rotate in opposite directions simultaneously under the meshing drive of the drive gear 1 - 74 and the passive gear 1 - 71 and the drive of the transmission belt. The incomplete gear 1 - 73 enables the two support shafts 62 to rotate intermittently, and the forward and reverse rotation of motor 1 - 72 ensures that the two support shafts 62 can rotate back, that is, the clamping part 63 can rotate intermittently in the forward and reverse directions along with the corresponding support shaft 62.

[0052] Refer to Figure 2 and Figures 9 - 11 As shown in FIGS. and, the discharging mechanism 8 includes discharging parts 81 provided at the front and rear ends of the U - shaped support frame 1 and on the left and right claw 632 on the same side. The discharging part 81 includes a receiving seat 811 jointly installed on the extension plate 348 and the U - shaped support frame 1. The end of the receiving seat 811 away from the U - shaped support frame 1 is a wedge - shaped structure. L - shaped baffles 812 are jointly installed on the left and right ends of the receiving seat 811 and the U - shaped support frame 1. Avoidance openings are left at the positions corresponding to the left and right lead screws 349 at the lower ends of the left and right L - shaped baffles 812 and the receiving seat 811. Arc - shaped through - holes 813 are formed in the middle of the left and right claws 632. Arc - shaped sliding rods 814 are arranged in the arc - shaped through - holes 813. One end of the arc - shaped sliding rod 814 is fixedly connected to the inner wall of the corresponding arc - shaped through - hole 813 near the tip of the claw 632, and the other end of the arc - shaped sliding rod 814 is fixedly connected to the inner wall of the corresponding arc - shaped through - hole 813 near the support shaft 62. A rectangular push plate 815 is slidably sleeved on the arc - shaped sliding rod 814. A compression spring is also sleeved on the arc - shaped sliding rod 814. One end of the compression spring is fixedly connected to the corresponding rectangular push plate 815, and the other end of the compression spring is fixedly connected to the inner wall of the corresponding arc - shaped through - hole 813 near the support shaft 62.

[0053] After the SBS particles in the bagged SBS are completely discharged, control the left and right electric telescopic rods 667 on the same side to drive the corresponding b-shaped slides 666 away from each other respectively. Multiple b-shaped slides 666 drive the corresponding transmission gear rings 665 away from each other respectively through the sleeves 663 until the left and right transmission gear rings 665 on the same side are disengaged from the corresponding incomplete gear rings 631 respectively. During this period, multiple mating sliders two 664 slide along the corresponding mating chutes two 662 respectively, and the left and right double telescopic rods 668 on the same side drive the corresponding sliding sleeves 635 closer to each other under the action of the lever principle. The left and right sliding sleeves 635 on the same side will drive the corresponding two alignment rods 637 to insert into the corresponding two alignment holes 633 respectively, so that the two claw hooks 632 on the front and back sides are both in the clamping state. Then, control the rotation of the incomplete gear one 73 by the forward and reverse motor one 72. The incomplete gear one 73 is transmitted with the passive gear one 71 to drive the rear support shaft 62 to rotate 180 degrees. At the same time, the transmission gear one 74 is transmitted with the passive gear one 71 and drives the front support shaft 62 to rotate 180 degrees synchronously under the transmission action of the transmission belt. At this time, the rotation directions of the front and rear support shafts 62 are opposite. The front and rear support shafts 62 drive the corresponding claw hooks 632 to rotate 180 degrees respectively through the corresponding incomplete gear rings 631. At this time, the two claw hooks 632 on the front and back sides respectively clamp half of the packaging bag and flip it from the rectangular through hole 61 to the outside of the C-shaped support frame 1.

[0054] Then, control the left and right electric telescopic rods 667 on the same side to drive the corresponding b-shaped slides 666 closer to each other respectively. Multiple b-shaped slides 666 drive the corresponding transmission gear rings 665 closer to each other respectively through the sleeves 663 until the left and right transmission gear rings 665 on the same side are restored to mesh with the corresponding incomplete gear rings 631 respectively. During this period, multiple mating sliders two 664 slide along the corresponding mating chutes two 662 respectively, and the left and right double telescopic rods 668 will drive the corresponding sliding sleeves 635 away from each other respectively. The left and right sliding sleeves 635 on the same side will drive the corresponding two alignment rods 637 to withdraw from the corresponding two alignment holes 633 respectively.

[0055] Then, the forward and reverse motor two 677 is used to control the connected rotating shaft two 676 to drive the driving gear 673 to rotate in the reverse direction. At this time, the two left and right claw hooks 632 on the corresponding side are driven to rotate in the reverse direction by 60 degrees around the support shaft 62 until the two claw hooks 632 on the same side are far away from each other and become in an open state. It should be noted that if the packaging of bagged SBS is not easily punctured by the claw hooks 632, the tips of multiple claw hooks 632 can adopt a needle-like structure. When the two left and right claw hooks 632 on the front and rear sides both puncture the bagged SBS and jointly clamp it, multiple rectangular push plates 815 will respectively slide adaptively along the corresponding arc-shaped slide bars 814 towards the end close to the support shaft 62, and multiple rectangular push plates 815 will always be located outside the packaging bag of bagged SBS. Under the action of the compression spring, the packaging bag of bagged SBS is pushed towards the tip of the claw hook 632. After the two claw hooks 632 on the same side are far away from each other and become in an open state, the two rectangular push plates 815 on the same side will jointly push the packaging bag of bagged SBS towards the tip of the claw hook 632 until half of the packaging bags on the front and rear sides are respectively separated from the claw hooks 632 and fall onto the material receiving seat 811 for unified recycling treatment.

[0056] Repeat the above operations to repeat the automatic feeding work of bagged SBS. The conveying mechanism 2, the material blocking and supporting mechanism 3, the clamping and limiting mechanism 6, the flipping mechanism 7, the facing cutting mechanism 4, and the discharging mechanism 8 cooperate to convey the bagged SBS from left to right to the two front and rear U-shaped support plates 344. The automatic bag opening work of cutting the middle part of the bagged SBS by using the upper elastic circular blade one 47 and the lower fixed circular blade two 52, and the puncturing and clamping work of multiple claw hooks 632 are carried out. Moreover, while controlling the material blocking plate 32 to descend, the two front and rear U-shaped support plates 344 can be controlled to change from the horizontal support state to the downward inclined state, so as to achieve the effect of automatically discharging the SBS particles in the bagged SBS, effectively avoiding the direct contact between workers and materials, reducing safety hazards and health risks. It can also drive the two claw hooks 632 on the front and rear sides to drive half of the packaging bag of bagged SBS to flip to the outside of the U-shaped support frame 1 respectively, and automatically separate the waste packaging bag from the claw hooks 632, facilitating the recycling work of the waste packaging bag.
