The rubber belt 2 is provided with a protrusion 22 adapted to the lower space 16, so that the lower space 16 can guide the protrusion 22 during the bonding process of the rubber belt 2 and the chain belt 1, thereby improving the accuracy of the splicing between the rubber belt 2 and the chain belt 1.

[0047] See also Figures 6 - 8 A chain belt processing and manufacturing device, the chain belt processing and manufacturing device is used to make the chain belt of the above-mentioned multi-layer waterproof zipper, which includes a first feeding mechanism 51, a second feeding mechanism 52, a third feeding mechanism 53 and a driving mechanism 54, the first feeding mechanism 51 is used to convey the chain belt 1 with the chain teeth 11 to the assembly station 61 of the assembly seat 6, the assembly station 61 is provided with a pressing plate 62 for pressing the chain belt 1, the pressing plate 62 is provided with a pressing tooth 63 for pressing the chain teeth 11, the assembly seat 6 realizes the fixing of the chain belt 1 on it through the clamping mechanism 7, the second feeding mechanism 52 is used to transfer the rubber belt 2 is transported to the bottom of the chain belt 1, the rubber belt 2 is segmented by the first cutting mechanism, the chain belt 1 and the chain teeth 11 are fixed to the rubber belt 2 by the bonding mechanism 8, the third feeding mechanism 53 is used to transport the rubber strip 3 to the positioning station 64 of the assembly seat 6, the rubber strip 3 is segmented by the second cutting mechanism, the rubber strip 3 is positioned between the rubber strip 3 and the chain teeth 11 of the chain belt 1 by the positioning mechanism 9, and the driving mechanism 54 is used to drive the rubber strip 3 to move horizontally and linearly in a direction perpendicular to the conveying direction of the chain belt 1, so that the rubber strip 3 is embedded in each chain tooth 11 of the chain belt 1.

[0048] The first feeding mechanism 51, the second feeding mechanism 52 and the third feeding mechanism 53 all include a conveying seat 55 and a conveying wheel unit 56. The conveying wheel unit 56 includes two conveying wheels 561 arranged in an upper and lower manner. The conveying wheels 561 are rotatably connected to the conveying seat 55. A first driving motor 562 for driving any one of the two conveying wheels 561 to rotate is installed on the conveying seat 55. The two conveying wheels 561 are connected to each other through a gear transmission mechanism and rotate in opposite directions. There is a gap 563 between the two conveying wheels 561 for the chain belt 1 or the rubber belt 2 or the rubber strip 3 to pass through. The driving effect of the first driving motor 562 causes the two conveying wheels 561 to rotate synchronously in opposite directions, thereby achieving the purpose of conveying the chain belt 1.

[0049] The first feeding mechanism 51 further includes a chain guide seat 57. An inverted L-shaped chain guide frame 58 is provided on the chain guide seat 57. A number of chain guide wheels 581 for guiding the chain belt 1 to change from horizontal conveyance to vertical conveyance are provided on the chain guide frame 58. The chain guide wheels 581 are arranged in a right triangle. A number of chain guide rods 583 for the chain belt 1 to wind around are provided on the longitudinal section 582 of the chain guide frame 58. The chain guide rods 583 are located below the chain guide wheels 581 and are arranged in a staggered manner in the vertical direction. A number of chain guide rollers 571 for the chain belt 1 to wind around are installed on the chain guide seat 57.

Through the settings of the chain guide wheels 581, the chain guide rods 583, and the chain guide rollers 571, the chain belt 1 can be conveyed to the assembly seat 6 in a specific form on the chain guide seat 57 and the chain guide frame 58, thereby ensuring the accuracy of the assembly of each component on the subsequent chain belt 1.

[0050] To ensure the conveying effect of the first feeding mechanism 51 on the chain belt 1, the first feeding mechanism 51 has two conveying seats 55. Conveying wheel group units 56 are provided on both of the two conveying seats 55. The assembly seat 6 is located between the two conveying seats 55. The second feeding mechanism 52 and the third feeding mechanism 53 are both located between the assembly seat 6 and the conveying seats 55.

[0051] In this embodiment, both the first cutting mechanism and the second cutting mechanism include cutting knives. A linear driving device for driving the cutting knife to move is installed on the assembly seat 6. The linear driving device adopts an electric push rod. The cutting knife is slidably arranged on the assembly seat 6. The moving direction of the cutting knife on the first cutting mechanism is perpendicular to the conveying direction of the rubber belt 2. The moving direction of the cutting knife on the second cutting mechanism is perpendicular to the conveying direction of the rubber strip 3.

[0052] See Figure 8 、 Figure 11 As shown in, the pressing mechanism 7 includes a rotating shaft 71 and two pressing strips 72 fixed to the rotating shaft 71. The rotating shaft 71 is rotatably arranged on the assembly seat 6. A second driving motor 73 for driving the rotating shaft 71 to rotate is installed on the assembly seat 6. The chain belt 1 is located on the rotation trajectory of the pressing strips 72. By driving the rotating shaft 71 to rotate through the second driving motor 73, the two pressing strips 72 can rotate synchronously in the same direction, so as to achieve the purpose of pressing the area to be assembled on the chain belt 1 between the pressing strips 72 and the assembly seat 6 or releasing the fixation of the chain belt 1 by the pressing strips 72 and the assembly seat 6, ensuring the stability of the form of the area to be assembled on the chain belt 1 during the assembly process, and further improving the assembly accuracy.

[0053] To improve the pressing effect on the chain belt 1, a rubber sheet 74 is provided on the side surface of the pressing strip 72 in contact with the chain belt 1.

[0054] See Figures 8 - 10, the positioning mechanism 9 includes a positioning plate 91, a lifting seat 92 and a sliding seat 93. The positioning plate 91 is slidably arranged on the assembly seat 6, and the driving mechanism 54 drives the positioning plate 91 to move horizontally in a straight line in a direction perpendicular to the conveying direction of the chain belt 1. A number of equally spaced positioning teeth 911 are provided on the positioning plate 91, so as to form a receiving groove 912 on the positioning plate 91 that is adapted to the rubber strip 3. The lifting seat 92 is slidably arranged on the assembly seat 6, and a first driving device 94 for driving the lifting seat 92 to lift vertically is installed on the assembly seat 6. A number of hook members 95 corresponding to the receiving grooves 912 one by one are slidably connected to the lifting seat 92. The rubber strip 3 is located between the hook end 951 of the hook member 95 and the positioning plate 91. A spring for applying a force to the hook member 95 to slide horizontally in a straight line in the direction of the chain belt 1 is provided between the sliding end 952 of the hook member 95 and the lifting seat 92. The two ends of the spring respectively abut against the sliding end 952 of the hook member 95 and the lifting seat 92. The sliding seat 93 is slidably arranged on the lifting seat 92, and a second driving device 96 for driving the sliding seat 93 to move horizontally in a straight line is installed on the lifting seat 92. The moving direction of the sliding seat 93 is the same as the conveying direction of the chain belt 1. The sliding end 952 of the hook member 95 is located on the moving track of the sliding seat 93. A guiding surface 931 for guiding the movement of the sliding end 952 of the hook member 95 is provided at the front end of the sliding seat 93 in its moving direction. A wire winding and unwinding device 97 is provided on the lifting seat 92. The pulling end 972 of the metal wire 971 on the wire winding and unwinding device 97 is fixed to the sliding seat 93, so that after the sliding seat 93 drives the hook member 95 to move, the metal wire 971 restricts the hook member 95 from resetting.

[0055] During use, the second driving device 96 drives the sliding seat 93 to move horizontally in a straight line. During the movement of the sliding seat 93, due to the guiding effect of the guiding surface 931 thereon, the hook end 951 of the hook member 95 moves towards the positioning plate 91 in sequence, so that the rubber strip 3 is gradually and completely hooked into the receiving groove 912. At the same time, since the sliding seat 93 will pull the metal wire 971 when it moves, the metal wire 971 is across the reset track of the sliding end 952 of the moved pulling member, thus achieving the effect of restricting the rubber strip 3 in the receiving groove 912 by the hook end 951 of the pulling member.

[0056] In this embodiment, the driving mechanism 54 includes a pushing seat 541. A linear driving device for driving the pushing seat 541 to move is installed on the assembly seat 6. The linear driving device adopts a double-rod cylinder. The pushing seat 541 is slidably arranged on the assembly seat 6. The positioning plate 91 is integrally connected to the pushing seat 541. The moving direction of the pushing seat 541 is perpendicular to the conveying direction of the chain belt 1.

[0057] In this embodiment, the first driving device 94 adopts a double-rod cylinder, and the second driving device 96 adopts a screw motor.

[0058] In this embodiment, a servo motor 98 for winding and unwinding is installed on the wire winding and unwinding device 97. When the sliding seat 93 slides and pulls the pulling end 972 of the metal wire 971 to move together, and when the sliding seat 93 resets, the servo motor 98 is driven to unwind and wind the wire respectively.

[0059] See Figure 11 、 Figure 12 , the bonding mechanism 8 includes a spraying seat 81 and a first push block 82 for lifting the rubber belt 2. The spraying seat 81 is located directly below the pressing plate 62. A number of spraying heads 83 for spraying glue are provided on the spraying seat 81. The spraying heads 83 correspond to the chain teeth 11 one by one. The spraying seat 81 is slidably arranged on the assembly seat 6. A third driving device 84 for driving the spraying seat 81 to move horizontally in a straight line is installed on the assembly seat 6. The moving direction of the spraying seat 81 is perpendicular to the conveying direction of the chain belt 1. A first conveying groove 85 for guiding the conveying of the rubber belt 2 is formed on the assembly seat 6. The cutting outlet of the first cutting mechanism is located on the side wall surface of the first conveying groove 85. The first push block 82 is slidably arranged on the bottom wall surface of the first conveying groove 85. A fourth driving device 86 for driving the first push block 82 to lift vertically is installed on the assembly seat 6.

[0060] During use, the third driving device 84 drives the spraying seat 81 to move horizontally in a straight line, so that the spraying heads 83 can move to directly below the corresponding chain teeth 11. Thus, the spraying heads 83 can spray glue on the chain teeth 11 and the bottom surface of the part of the chain belt 1 close to the chain teeth 11. Combining with the lifting driving effect of the fourth driving device 86 on the first push block 82, the rubber belt 2 separated by the first cutting mechanism is driven by the first push block 82 to lift. Then, under the mutual clamping of the pressing plate 62 and the first push block 82, the rubber belt 2 is adhesively fixed to the contacted chain teeth 11 and chain belt 1 under the action of the glue.

[0061] When the fourth driving device 86 drives the first push block 82 to lift, the third driving device 84 drives the spraying seat 81 to reset, thus avoiding the obstruction of the spraying seat 81 to the movement of the first push block 82 and ensuring the smoothness between the operation processes of the equipment.

[0062] In this embodiment, both the third driving device 84 and the fourth driving device 86 adopt double-rod cylinders.

[0063] See Figure 13 、 Figure 14, a second conveying groove 87 for guiding the conveying of the rubber strip 3 is formed on the assembly seat 6. The cutting edge of the second cutting mechanism is located on the side wall surface of the second conveying groove 87. A second push block 88 for lifting the rubber strip 3 is slidably arranged on the bottom wall surface of the second conveying groove 87. A fifth driving device 89 for driving the second push block 88 to vertically lift and lower is installed on the assembly seat 6. In this embodiment, the fifth driving device 89 adopts a double-rod cylinder.

[0064] Through the arrangement of the second conveying groove 87 and the second push block 88 therein, combined with the driving effect of the fifth driving device 89 on the second push block 88, the rubber strip 3 separated by the second cutting mechanism in the second conveying groove 87 can be lifted to the same height as the positioning plate 91 under the drive of the second push block 88, avoiding the movement obstruction between adjacent mechanisms, thereby ensuring the smooth movement of each assembly component.

[0065] The usage method of the chain belt processing and manufacturing equipment is as follows:

[0066] Step 1: Convey the chain belt with chain teeth to the assembly station of the assembly seat through the first feeding mechanism. At this time, the chain belt is pressed between the pressing plate and the assembly seat, and the pressing teeth on the pressing plate correspond to the chain teeth on the chain belt one by one. Subsequently, fix the chain belt located on the assembly seat to the assembly seat through the pressing mechanism (as Figure 9 , Figure 15 shown in sequence);

[0067] Step 2: Convey the rubber belt to directly below the chain belt through the second feeding mechanism. Then, cut the rubber belt through the first cutting mechanism. At this time, the cut rubber belt is located on the first push block. Then, drive the spraying seat of the bonding mechanism to move into the first conveying groove through the third driving device (as Figure 12 shown), and spray glue on the chain belt between adjacent chain teeth through the spray head. After the glue spraying is completed, the third driving device drives the spraying seat of the bonding mechanism to reset. Subsequently, drive the first push block through the fourth driving device to drive the rubber belt on the first push block to move vertically upward until the rubber belt fits on the chain belt. At this time, the convex blocks on the rubber belt are located in the lower space between adjacent chain teeth, and under the mutual clamping of the pressing plate and the first push block, the rubber belt is bonded and fixed to the contacted chain teeth and chain belt under the action of the glue, thus completing the assembly of the rubber belt on the chain belt;

[0068] Step 3: Convey the rubber strip to the positioning station of the assembly seat through the third feeding mechanism. Then, cut the rubber strip through the second cutting mechanism. At this time, the cut rubber strip is located on the second push block. Subsequently, drive the second push block through the fifth driving device to drive the rubber strip on the second push block to move vertically upward, so that the rubber strip is located between the hook end of the hook member and the positioning plate;

[0069] Step 4: Position the rubber strip relative to the teeth on the chain belt through the positioning mechanism. During the sliding of the sliding seat, the sliding ends of the respective hook members are sequentially pushed, causing the hook ends of the respective hook members to gradually pull the rubber strip into the receiving groove of the positioning plate. At the same time, the metal wire pulled out by the sliding seat restricts the hook members that are pushed by the sliding seat to move from resetting under the action of the spring (as shown in Figure 15 , Figure 16 and Figure 17 in sequence);

[0070] Step 5: Drive the lifting seat to move vertically upward through the first driving device, so that the hook end of the hook member moves away from between the rubber strip and the chain belt.
