Description

Technical Field

[0001] This invention relates to the field of waterproof membrane production technology, specifically to a processing device for asphalt waterproof membrane. Background Technology

[0002] There are generally three types of sand-coated bitumen waterproof membranes: the first type has both sides fully covered with sand; the second type has only one side fully covered with sand; and the third type has a single side with alternating strips of sand on one side. Figure 1 The diagram shows a schematic of a single-sided, spaced-out strip sand-coated structure for asphalt waterproof membrane in the prior art. In the production process of this single-sided sand-coated strip structure, multiple first discharge ports are spaced out at the bottom of the first hopper. Sand and gravel fall onto the asphalt waterproof membrane during its spreading phase through these ports, thus achieving the single-sided, spaced-out strip sand-coated structure 2 of the asphalt waterproof membrane 1. However, in the existing process of arranging the single-sided sand-coated strip structure 2 of the asphalt waterproof membrane 1, the sand and gravel are unevenly dispersed, affecting the yield rate. Furthermore, in the existing sand-coating equipment, uneven structures 3 easily appear on the two sides of the sand-coated strip structure 2 during the sand-coating process. Summary of the Invention

[0003] The main objective of this invention is to provide a processing device for asphalt waterproof membrane to solve the problem of uneven dispersion of strip-shaped sand and gravel in the existing sand coating process.

[0004] To achieve the above objectives, the present invention provides a processing apparatus for asphalt waterproof membrane, comprising a support, an laying roller, and a sand and gravel channel;

[0005] The top of the support is equipped with a hopper for holding sand and gravel, and the bottom of the hopper has a discharge port with an opening and closing door.

[0006] The erecting roller is located below the material discharge port, with its axis perpendicular to the direction of the asphalt waterproof membrane fabrication and erected on the support frame.

[0007] There are multiple sand and gravel channels, which are arranged at intervals along the axial direction of the erecting roller and located below the erecting roller. The top of each sand and gravel channel is an open structure, and the bottom of each sand and gravel channel has a material leakage port.

[0008] A recycling conveyor belt is set along the axial direction of the laying roller and is located directly below multiple material discharge ports. Asphalt waterproof membrane is installed below the recycling conveyor belt.

[0009] A preferred embodiment further includes a first cylinder, the piston rod of which is hinged to the opening and closing door, and the cylinder seat of which is hinged to the hopper.

[0010] A preferred embodiment is that the sand and gravel channel comprises a left rectangular shell and a right rectangular shell;

[0011] The top of the left rectangular shell is provided with a second opening structure, and the side wall of the left rectangular shell is provided with a second notch;

[0012] The top of the right rectangular shell is provided with a third opening structure, and the side wall of the right rectangular shell is provided with a third notch;

[0013] Both the left and right rectangular shells have a fourth opening structure on one side;

[0014] The fourth opening structure of the right rectangular shell passes through the fourth opening structure of the left rectangular shell, and the left rectangular shell is built inside the right rectangular shell;

[0015] The second and third open structures form the first open structure;

[0016] The second and third notches form a material leakage port.

[0017] A preferred embodiment further includes a control unit, which comprises an upper adjusting rod and a lower adjusting rod, both of which are axially arranged on the roller.

[0018] The upper adjusting rod is connected to a first driving component for moving along the axial direction of the laying roller;

[0019] The lower adjusting rod is connected to a second drive component for moving along the axial direction of the laying roller;

[0020] Multiple first mounting blocks are arranged at intervals along the axial direction on the upper adjusting rod. Each of the multiple first mounting blocks corresponds to a multiple left rectangular shell and is fixedly connected.

[0021] The lower adjusting rod has multiple second mounting blocks arranged at intervals along the axial direction. Each of the multiple second mounting blocks corresponds to a multiple right rectangular housing and is fixedly connected.

[0022] A preferred embodiment is that the first driving component is a second cylinder, the cylinder seat of the second cylinder is fixedly connected to the bracket, and the piston rod of the second cylinder is coaxially connected to the upper adjusting rod.

[0023] A preferred embodiment is that the second driving component is a third cylinder, the cylinder seat of the third cylinder is fixedly connected to the bracket, and the piston rod of the third cylinder is coaxially connected to the lower adjusting rod.

[0024] The beneficial effects of the above scheme are as follows: First, sand and gravel are put into the hopper, and the asphalt waterproof membrane is driven to spread. The opening and closing gate is opened and closed appropriately, and the sand and gravel leak from the discharge port onto the laying roller. Furthermore, through multiple sand and gravel channels arranged at intervals along the axial direction of the laying roller, some of the sand and gravel fall into multiple sand and gravel channels. The sand and gravel that fall into multiple sand and gravel channels fall into the recycling conveyor belt through the discharge port, and drive the recycling conveyor belt to recycle the sand and gravel. Another part of the sand and gravel passes through the gap between two sand and gravel channels and falls onto the asphalt waterproof membrane. Thus, the sand covering process of the single-sided noodle structure of the asphalt waterproof membrane is realized.

[0025] The sand and gravel leak from the discharge port onto the laying roller, which helps to further spread the sand and gravel, making the sand covering more uniform. Some of the sand and gravel passes through the gap between the two sand and gravel channels and falls onto the asphalt waterproof membrane, which avoids the uneven structure of the sand covering strip structure on both sides of the sand covering strip structure.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0037] First embodiment:

[0038] like Figures 2 to 7 As shown, a processing device for asphalt waterproof membrane according to this embodiment includes a support 10, an laying roller 20, and sand and gravel channels 30. A hopper 12 for placing sand and gravel is provided at the top of the support 10, and a discharge port 13 is opened at the bottom of the hopper 12, with an opening and closing door 14. The laying roller 20 is located below the discharge port 13, perpendicular to the fabric direction of the asphalt waterproof membrane 1, and is laid on the support 10. Multiple sand and gravel channels 30 are arranged at intervals along the axial direction of the laying roller 20 and located below the laying roller 20. The top of each sand and gravel channel 30 has a first open structure 31, and the bottom of each sand and gravel channel 30 has a discharge port 32. The processing device for asphalt waterproof membrane in this embodiment also includes a recycling conveyor belt 40. The conveying direction of the recycling conveyor belt 40 is arranged along the axial direction of the laying roller 20 (that is, the conveying direction of the recycling conveyor belt 40 is parallel to the axial direction of the laying roller 20), and it is located directly below a plurality of material discharge ports 32. The asphalt waterproof membrane 1 is arranged below the recycling conveyor belt 40.

[0039] like Figure 7 As shown, where Figure 7The middle arrow indicates the direction of the asphalt waterproof membrane 1. First, sand and gravel are put into the hopper 12, and the asphalt waterproof membrane 1 is driven to move. The opening and closing gate 14 is opened and closed appropriately, and the sand and gravel leak from the discharge port 13 onto the laying roller 20. Further, through multiple sand and gravel channels 30 arranged at intervals along the axial direction of the laying roller 20, some sand and gravel fall into multiple sand and gravel channels 30. The sand and gravel falling into multiple sand and gravel channels 30 fall into the recycling conveyor belt 40 through the discharge port 32, and drive the recycling conveyor belt 40 to recycle the sand and gravel. Another part of the sand and gravel passes through the gap between two sand and gravel channels 30 and falls onto the asphalt waterproof membrane 1. Thus, the sand covering process of the single-sided noodle structure 2 of the asphalt waterproof membrane 1 is realized.

[0040] Additionally, the recycling conveyor belt 40 is located below the sand and gravel channel, and the side of the recycling conveyor belt 40 closest to the laying roller 20 is directly below the material outlet 32. The other side of the recycling conveyor belt 40 is positioned away from the fabric feeding direction. Figure 7 As shown. In this process, the sand and gravel leak from the discharge port 13 onto the laying roller 20, which helps to further spread the sand and gravel, making the sand covering more uniform. Some of the sand and gravel passes through the gap between the two sand and gravel channels 30 and falls onto the asphalt waterproof membrane 1, which avoids the uneven structure 3 of the sand covering strip structure 2 from easily appearing on both sides of the sand covering strip structure 2.

[0041] The processing device for asphalt waterproof membrane also includes a first cylinder 15, the piston rod of which is hinged to the opening and closing door 14, and the cylinder seat of which is hinged to the hopper 12. The first cylinder 15 helps to control the flow rate of sand and gravel.

[0042] In addition, the laying roller 20 is perpendicular to the direction of the asphalt waterproof membrane 1 and is laid on the support 10, which helps the laying roller 20 to move. The laying roller 20 is misaligned with multiple sand and gravel channels 30, so that sand and gravel do not pass through the sand and gravel channels 30, thus achieving full sand coverage on one side of the asphalt waterproof membrane 1.

[0043] It is important to emphasize the misalignment of the laying roller 20 and the multiple sand and gravel channels 30. First, the laying roller 20 moves in the fabric-feeding direction until it reaches a specific position, driving the asphalt waterproof membrane 1 to spread. The opening and closing gate 14 opens and closes slightly, allowing sand and gravel to leak from the discharge port 13 onto the laying roller 20. The sand and gravel falling from the laying roller 20 no longer pass through the multiple sand and gravel channels 30 or the gaps between them, thus achieving complete sand coverage on one side of the asphalt waterproof membrane 1. This structural setup allows for rapid switching between two modes: complete sand coverage on one side of the asphalt waterproof membrane and alternating strip sand coverage on one side.

[0044] Second embodiment:

[0045] like Figure 5 , Figure 6As shown, the sand and gravel channel 30 includes a left rectangular shell 33 and a right rectangular shell 34. The top of the left rectangular shell 33 has a second opening structure 330, and the side wall of the left rectangular shell 33 has a second notch 331. The top of the right rectangular shell 34 has a third opening structure 340, and the side wall of the right rectangular shell 34 has a third notch 341. Both the left and right rectangular shells 33 and 34 have a fourth opening structure 35 on one side. The fourth opening structure 35 of the right rectangular shell 34 passes through the fourth opening structure 35 of the left rectangular shell 33, and the left rectangular shell 33 is built inside the right rectangular shell 34. The second opening structure 330 and the third opening structure 340 form a first opening structure 31. The second notch 331 and the third notch 341 form a material discharge port 32.

[0046] The processing device for asphalt waterproof membrane also includes a control unit 50, which includes an upper adjusting rod 51 and a lower adjusting rod 52. Both the upper adjusting rod 51 and the lower adjusting rod 52 are arranged along the axial direction of the laying roller 20 (i.e., the axial directions of the upper adjusting rod 51 and the lower adjusting rod 52 are parallel to the axial direction of the laying roller 20). The upper adjusting rod 51 is connected to a first driving member 510 for moving along the axial direction of the laying roller 20. The lower adjusting rod 52 is connected to a second driving member 520 for moving along the axial direction of the laying roller 20. Multiple first mounting blocks 53 are arranged at intervals along the axial direction of the upper adjusting rod 51, each corresponding to and fixedly connected to multiple left rectangular shells 33. Multiple second mounting blocks 54 are arranged at intervals along the axial direction of the lower adjusting rod 52, each corresponding to and fixedly connected to multiple right rectangular shells 34. The first driving member 510 is a second cylinder, the cylinder seat of which is fixedly connected to the bracket 10, and the piston rod of which is coaxially connected to the upper adjusting rod 51. The second driving component 520 is the third cylinder. The cylinder seat of the third cylinder is fixedly connected to the bracket 10, and the piston rod of the third cylinder is coaxially connected to the lower adjusting rod 52.

[0047] The specific operation of the above embodiments is as follows:

[0048] The piston rods of the second and third cylinders are driven to extend and retract, which in turn drive the upper adjusting rod 51 and the lower adjusting rod 52 to move axially along the laying roller 20. The upper adjusting rod 51 drives multiple left rectangular shells 33 to move laterally through multiple first mounting blocks 53. The lower adjusting rod 52 drives multiple right rectangular shells 34 to move laterally through multiple second mounting blocks 54. The lateral movement of the multiple right rectangular shells 34 and the lateral movement of the left rectangular shells 33 cause the width of the multiple sand and gravel channels 30 to either increase or decrease in length.

[0049] When the width of multiple sand and gravel channels 30 increases, the gap between two sand and gravel channels 30 becomes smaller, and the width of the strip sand covering that the sand and gravel fall through the gap onto the asphalt waterproof membrane 1 becomes smaller. This structure enables the adjustment of the width of multiple sand covering strip structures 2.

[0050] Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
