Description

Technical Field

[0001] The present invention belongs to the technical field of safety net manufacturing, and particularly relates to a hot melting device for a wire drawing machine in safety net production. Background Art

[0002] A safety net is a net set under or beside high-altitude building construction equipment or during art performances to play a protective role to prevent accidents caused by the fall of people or objects. The safety net is composed of a net body, edge ropes, tie ropes, and rib ropes. The net body is woven by net ropes and has diamond-shaped or square mesh openings. During the production process of the safety net, a wire drawing machine is required to draw plastic, and the produced wire rods need to be accurately cut into various appropriate lengths according to different actual requirements for subsequent safety net weaving work.

[0003] At present, after the wire drawing machine finishes drawing the wire rods, the existing process usually involves winding the wire rods first. This step itself is for the convenience of storing and transporting the wire rods, but from the perspective of subsequent cutting processes, it brings some troubles. When it is necessary to cut the wound wire rods, the operator has to first unwind the wire rods, which requires a lot of time and effort. On the one hand, the wound wire rods often have a certain tightness and winding force. To unwind them smoothly, it is necessary to overcome the friction between the wire rods and the tension during winding. This not only requires a high level of technical proficiency from the operator, but also if not careful during the unwinding process, the wire rods may be distorted, knotted, etc., affecting the quality of the wire rods. On the other hand, due to the wire rods being bent and rubbed multiple times during winding and unwinding, it may have a certain impact on the smoothness of their surface and internal structure, thereby affecting the quality and performance of the final safety net product.

[0004] Therefore, there is an urgent need to provide a hot melting device for a wire drawing machine in safety net production to solve the above problems. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the above-mentioned disadvantages of the prior art and provide a hot melting device for a wire drawing machine in safety net production.

[0006] The technical solution adopted to solve the above technical problem is: to provide a hot melting device for a wire drawing machine in safety net production, including a box body, an inlet pipe is fixedly installed inside the box body, an extruder is fixedly installed inside the box body, and further includes;

[0007] An adjustment mechanism is rotatably connected inside the box body, the adjustment mechanism is fixedly installed at the other end of the extruder, a spraying mechanism is fixedly installed on the surface of the box body, and a cooling water tank is fixedly installed on one side of the box body;

[0008] A driving mechanism is fixedly installed on the surface of the cooling water tank. A propulsion mechanism is rotatably connected to the surface of the cooling water tank. A cutting mechanism is fixedly installed on the surface of the cooling water tank. The driving mechanism is used to drive the propulsion mechanism to advance and the cutting mechanism to cut.

[0009] The present invention is further configured as follows: An outlet is provided on one side of the box body. An auxiliary roller is rotatably connected inside the outlet. A bolt is threadedly connected to the bottom of the box body. A cover plate is hinged to the surface of the feed pipe. One end of the extruder is fixedly connected to the inside of the feed pipe. The other end of the extruder is fixedly installed with a protective cover.

[0010] Through the above technical solution, the outlet is used for the made wire to be moved out of the box body and into the cooling water tank for secondary cooling. The auxiliary roller plays an auxiliary role to facilitate the forward transportation of the wire. The bolt cooperates with the mold, the mounting table and the screw holes inside the fixing table to realize the fixation of the mold inside the mounting groove and at the same time realize the fixation of the mounting table inside the fixing table. The plastic raw material is transported to the inside of the extruder through the feed pipe for wire drawing work. The cover plate prevents external dust or impurities from entering the inside of the extruder and affecting the quality of the wire. The protective cover protects the freshly extruded wire and guides the wire to move to the mold.

[0011] The present invention is further configured as follows: The adjustment mechanism includes a mounting table. Anti-slip bumps are fixedly installed on the surface of the mounting table. A plurality of through holes are provided on the surface of the mounting table. A plurality of mounting grooves are provided on the surface of the mounting table. The plurality of through holes and mounting grooves are distributed in a ring shape. Guide grooves are provided on both sides of the mounting groove. A mold is detachably installed inside the mounting groove. Guide blocks are fixedly installed on both sides of the mold. The guide blocks are slidably connected inside the guide grooves. Screw holes are provided on both the mold and the surface of the mounting table. The bolt is threadedly connected inside the screw holes. Symmetric fixing tables are fixedly installed inside the box body. Rotating grooves are provided on the surface of the fixing tables. The mounting table is rotatably connected inside the rotating grooves. A screw hole is provided inside one of the fixing tables. The screw hole inside the fixing table, the screw hole on the surface of the mold and each screw hole on the surface of the mounting table are in the same vertical plane.

[0012] Through the above technical solution, the mounting table is used for the installation of molds of different sizes, so as to facilitate the extrusion of wires of different sizes. The anti-slip bumps are provided to facilitate the rotation of the mounting table. The size of the through holes is the same as the size of the corresponding mold. The mold is placed inside the mounting groove and is fixed by the cooperation of the bolt and the screw hole. The guide grooves and the guide blocks cooperate to enable the mold to be stably inserted into the mounting groove. The two fixing tables limit the mounting table to prevent the mounting table from moving. The rotating grooves facilitate the rotation of the mounting table, thereby realizing the switching of different molds.

[0013] The present invention is further configured as follows: The spraying mechanism includes a cold water tank, which is fixedly installed on the surface of the box body. A water pipe is fixedly connected inside the cold water tank, and a spray head is fixedly installed at the end of the water pipe. The spray head is fixedly installed inside the box body.

[0014] Through the above technical solution, after the wire is made, it is moved out from inside the through hole and is in a high-temperature state. At this time, the cooling water inside the cold water tank sprays the wire through the spray head, realizing the cooling treatment of the wire and facilitating subsequent work.

[0015] The present invention is further configured as follows: A plurality of guide rollers are fixedly installed inside the cooling water tank. A support frame is fixedly installed on the surface of the cooling water tank. A jack is provided on one side of the support frame. A condenser is fixedly installed on the lower surface of the cooling water tank.

[0016] Through the above technical solution, the cooling water tank performs secondary cooling on the wire and cleans the surface of the wire. One guide roller is located inside the cooling water tank, enabling the wire to move inside the cooling water tank. Another guide roller is higher than the cooling water tank and transports the wire to the propulsion mechanism.

[0017] The present invention is further configured as follows: The driving mechanism includes a motor, which is fixedly installed on the surface of the support frame. The output end of the motor is drivingly connected to a transmission rod. A driving sprocket is fixedly installed on the surface of the transmission rod. A large bevel gear is fixedly installed at the end of the transmission rod.

[0018] Through the above technical solution, when the motor is started, the transmission rod drives the large bevel gear to rotate. Due to the meshing relationship between the large bevel gear and the small bevel gear, the small bevel gear rotates, realizing the propulsion work of the propulsion mechanism. At the same time, through the meshing action of the driving sprocket, the driven sprocket and the chain, the cutting mechanism can cut the wire. When the large bevel gear rotates one circle, the small bevel gear rotates several circles, so that the cutting knife can cut the wire when the wire is transported over a long distance.

[0019] The present invention is further configured as follows: The propulsion mechanism includes a rotating rod, which is rotatably connected inside the support frame. A small bevel gear is fixedly installed on the surface of the rotating rod. The small bevel gear meshes with the large bevel gear. A first turntable is fixedly installed on the surface of the rotating rod. A first fixing strip and a second fixing strip are fixedly installed on the surface of the first turntable. Two fixing blocks are fixedly installed inside the support frame. A first support column is fixedly installed on the surface of one fixing block. The end of the first support column is rotatably connected to a second turntable. A second support column is fixedly installed on the surface of the other fixing block. A third turntable is rotatably connected to the surface of the second support column. The second turntable and the third turntable are in the same vertical plane.

[0020] Through the above technical solution, when the rotating rod rotates, it drives the first turntable to rotate. When the first turntable rotates, the second turntable can rotate by the engagement of the first fixing strip on the surface of the first fixing strip and the first ring block or the engagement of the second fixing strip on the surface of the second fixing strip and the second ring block. The wire is located in the middle of the second turntable and the third turntable. When the second turntable rotates, it cooperates with the third turntable to push the wire, which is convenient for subsequent cutting. The first support column and the second support column support the second turntable and the third turntable respectively.

[0021] The present invention is further configured as follows: a screw sleeve groove is provided inside the first support column, and a plurality of support grooves are provided on the surfaces of the first support column and the second turntable. A bidirectional lead screw is rotatably connected inside the first support column. One end of the bidirectional lead screw is fixedly installed with a turntable. A plug pin is movably inserted on the surface of the turntable. A jack is provided on one side of the support frame, and the plug pin is movably inserted inside the jack.

[0022] Through the above technical solution, the settings of the screw sleeve groove and the support groove facilitate the movement of the screw sleeve and the support. When the bidirectional lead screw rotates, the two screw sleeves approach or move away from each other. The settings of the plug pin and the jack fix the bidirectional lead screw after rotation is completed, avoiding the reverse rotation of the bidirectional lead screw.

[0023] The present invention is further configured as follows: a chute is provided on the surface of the second turntable. A first ring block and a second ring block are slidably connected to the surface of the chute. A plurality of supports are fixedly connected inside the first ring block and the second ring block. The ends of the plurality of supports are all fixedly installed with screw sleeves. The two screw sleeves are both threadedly connected to the surface of the bidirectional lead screw. A plurality of first fixing strips are fixedly installed on the surface of the first ring block. A plurality of second fixing strips are fixedly installed on the surface of the second ring block. The first fixing strip on the surface of the first ring block is movably engaged with the first fixing strip on the surface of the first turntable. The second fixing strip on the surface of the second ring block is movably engaged with the second fixing strip on the surface of the first turntable. The two screw sleeves are both slidably connected inside the screw sleeve groove, and the plurality of supports are all slidably connected inside the support groove.

[0024] Through the above technical solution, the setting of the chute facilitates the movement of the first ring block and the second ring block. In the initial state, the first fixing strip on the surface of the first turntable is engaged with the first fixing strip on the surface of the first ring block. At this time, the pushing distance of the wire is short, and the cutting knife can cut out a wire of a short length. When it is necessary to cut wires of different lengths, the bidirectional lead screw is rotated through the turntable, and the two screw sleeves approach, so that the first ring block and the second ring block are attached. At this time, the first fixing strip on the surface of the first ring block is far away from the first fixing strip on the surface of the first turntable, and the second fixing strip on the surface of the second ring block is engaged with the second fixing strip on the surface of the second turntable, and the pushing distance of the wire is long, and the cutting knife can cut out a wire of a long length.

[0025] The present invention is further configured as follows: The cutting mechanism includes a reciprocating lead screw. A connecting plate is fixedly connected inside the support frame. The reciprocating lead screw is rotatably connected to the surface of the connecting plate. A driven sprocket is fixedly installed at the end of the reciprocating lead screw. A chain meshes with the surfaces of the driving sprocket and the driven sprocket. A moving frame is threadedly connected to the surface of the reciprocating lead screw. A cutting knife is fixedly installed inside the moving frame.

[0026] Through the above technical solution, when the transmission rod rotates, the driving sprocket rotates. Through the meshing of the driving sprocket, the driven sprocket and the chain, the reciprocating lead screw can rotate. The moving frame drives the cutting knife to move downwards to cut the wire, realizing equidistant cutting of wires of different lengths. The connecting plate supports the wire, facilitating cutting.

[0027] The beneficial effects of the present invention are as follows:

[0028] 1. The present invention is provided with a propulsion mechanism. The propulsion mechanism can push the wire forward and cooperate with the cutting mechanism to cut the wire. The propulsion mechanism can be adjusted. According to the different required wire lengths, the positions of the first ring block and the second ring block are moved. It can make the first fixing strip on the surface of the second turntable mesh with the first fixing strip on the surface of the first ring block or the second fixing strip on the surface of the second turntable mesh with the second fixing strip on the surface of the second ring block. The two methods can be switched to realize the propulsion of the wire at different distances and complete the cutting.

[0029] 2. The present invention is provided with an adjustment mechanism. The installation table is arranged inside the box body and can be manually rotated by the staff, so as to select different die sizes for wire manufacturing. At the same time, the die on the surface of the installation table can be disassembled, and the worn die can be replaced in time. Through the cooperation of bolts with the die, the installation table and the screw holes inside the fixed table, the fixation of the die inside the installation groove is realized, and at the same time, the fixation of the installation table inside the fixed table is realized.

One end of the extruder 3 is fixedly connected to the inside of the feed pipe 2, and a protective cover 31 is fixedly installed at the other end of the extruder 3.

[0045] In this embodiment, further, the outlet 11 is used for the made wire to be moved out of the box body 1 and into the cooling water tank 6 for secondary cooling. The auxiliary roller 12 plays an auxiliary role to facilitate the forward conveyance of the wire. The bolt 13 cooperates with the mold 43, the mounting table 41 and the screw holes 432 inside the fixed table 44 to fix the mold 43 inside the mounting groove 42, and at the same time fix the mounting table 41 inside the fixed table 44. The plastic raw material is conveyed through the feed pipe 2 to the inside of the extruder 3 for wire drawing work. The cover plate 21 prevents external dust or impurities from entering the inside of the extruder 3 and affecting the quality of the wire. The protective cover 31 protects the freshly extruded wire and guides the wire to the mold 43.

The screw hole 432 inside the fixed table 44, the screw hole 432 on the surface of the mold 43 and each screw hole 432 on the surface of the mounting table 41 are in the same vertical plane.

[0048] Furthermore, in this embodiment, the mounting table 41 is used for mounting molds 43 of different sizes, so as to facilitate the extrusion of wire rods of different sizes. The anti-slip bumps 411 are provided to facilitate the rotation of the mounting table 41. The size of the through hole 412 is consistent with the size of the corresponding mold 43. The mold 43 is placed inside the mounting groove 42 and is fixed by the cooperation of the bolt 13 and the screw hole 432. The guide groove 421 cooperates with the guide block 431 to enable the mold 43 to be stably inserted into the mounting groove 42. The two fixing platforms 44 limit the mounting table 41 to prevent the mounting table 41 from moving. The rotation groove 441 facilitates the rotation of the mounting table 41, thereby realizing the switching of different molds 43.

[0049] As Figure 2 shown, the spraying mechanism 5 includes a cold water tank 51. The cold water tank 51 is fixedly installed on the surface of the box body 1. A water pipe 52 is fixedly connected inside the cold water tank 51. A spray head 53 is fixedly installed at the end of the water pipe 52. The spray head 53 is fixedly installed inside the box body 1.

[0050] Furthermore, in this embodiment, after the wire rod is made, it moves out from inside the through hole 412 and is in a high-temperature state. At this time, the cooling water inside the cold water tank 51 sprays the wire rod through the spray head 53 to realize the cooling treatment of the wire rod, which is convenient for subsequent work.

[0051] As Figure 2 shown, a plurality of guide rollers 61 are fixedly installed inside the cooling water tank 6. A support frame 62 is fixedly installed on the surface of the cooling water tank 6. A jack 621 is opened on one side of the support frame 62. A condenser 63 is fixedly installed on the lower surface of the cooling water tank 6.

[0052] Furthermore, in this embodiment, the cooling water tank 6 performs secondary cooling on the wire rod and cleans the surface of the wire rod. One guide roller 61 is located inside the cooling water tank 6 to enable the wire rod to move inside the cooling water tank 6. The other guide roller 61 is higher than the cooling water tank 6 to convey the wire rod to the propulsion mechanism 8.

[0053] A driving mechanism 7 is fixedly installed on the surface of the cooling water tank 6. A propulsion mechanism 8 is rotatably connected to the surface of the cooling water tank 6. A cutting mechanism 9 is fixedly installed on the surface of the cooling water tank 6. The driving mechanism 7 is used to drive the propulsion mechanism 8 to propel and the cutting mechanism 9 to cut.

[0054] As Figure 2 、 Figure 5 and Figure 6 shown, the driving mechanism 7 includes a motor 71. The motor 71 is fixedly installed on the surface of the support frame 62. The output end of the motor 71 is drivingly connected with a transmission rod 72. A driving sprocket 721 is fixedly installed on the surface of the transmission rod 72. A large bevel gear 73 is fixedly installed at the end of the transmission rod 72.

[0055] In this embodiment, further, when the motor 71 starts, the transmission rod 72 drives the large bevel gear 73 to rotate. Due to the meshing relationship between the large bevel gear 73 and the small bevel gear 811, the small bevel gear 811 rotates, realizing the propulsion work of the propulsion mechanism 8. At the same time, through the meshing action of the driving sprocket 721, the driven sprocket 911 and the chain 722, the cutting mechanism 9 can cut the wire. When the large bevel gear 73 rotates one circle, the small bevel gear 811 rotates several circles, so that the cutting knife 93 can cut the wire when the wire is conveyed over a long distance.

[0056] As Figure 2 shown in Figure 5 FIG. [FIGURE NUMBER], the propulsion mechanism 8 includes a rotating rod 81. The rotating rod 81 is rotatably connected inside the support frame 62. A small bevel gear 811 is fixedly installed on the surface of the rotating rod 81. The small bevel gear 811 meshes with the large bevel gear 73. A first turntable 82 is fixedly installed on the surface of the rotating rod 81. A first fixing strip 821 and a second fixing strip 822 are fixedly installed on the surface of the first turntable 82. Two fixing blocks 83 are fixedly installed inside the support frame 62. A first support column 831 is fixedly installed on the surface of one fixing block 83.

A third turntable 871 is rotatably connected to the surface of the second support column 87. The second turntable 832 and the third turntable 871 are in the same vertical plane.

[0057] In this embodiment, further, when the rotating rod 81 rotates, it drives the first turntable 82 to rotate. When the first turntable 82 rotates, the second turntable 832 can rotate through the meshing of the first fixing strip 821 on the surface of the first fixing strip 821 and the first fixing strip 821 on the surface of the first ring block 85 or the meshing of the second fixing strip 822 and the second fixing strip 822 on the surface of the second ring block 86. The wire is located between the second turntable 832 and the third turntable 871. When the second turntable 832 rotates, it cooperates with the third turntable 871 to realize the propulsion of the wire, facilitating subsequent cutting. The first support column 831 and the second support column 87 respectively support the second turntable 832 and the third turntable 871.

[0058] As Figure 5 shown in Figure 6 FIG. [FIGURE NUMBER], Figure 7 FIG. [FIGURE NUMBER], Figure 8 shown in Figure 11 FIG. [FIGURE NUMBER], a screw sleeve groove 8311 is opened inside the first support column 831. A plurality of support grooves 8312 are opened on the surfaces of the first support column 831 and the second turntable 832. A bidirectional lead screw 84 is rotatably connected inside the first support column 831. A turntable 841 is fixedly installed at one end of the bidirectional lead screw 84. A pin 842 is movably inserted into the surface of the turntable 841. A jack 621 is opened on one side of the support frame 62. The pin 842 is movably inserted into the jack 621.

[0059] Please note that the [FIGURE NUMBER] in the translation should be replaced with the actual figure number in the original patent text. Also, the -

[0059] tags are preserved as they are.​Further in this embodiment, the settings of the bushing groove 8311 and the support groove 8312 facilitate the movement of the bushing 852 and the support 851. When the bidirectional lead screw 84 rotates, the two bushings 852 approach or move away from each other. The pin 842 and the jack 621 are provided to fix the bidirectional lead screw 84 after rotation is completed, preventing the bidirectional lead screw 84 from rotating back.

[0060] As Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 11 shown, a chute 833 is formed on the surface of the second turntable 832. A first ring block 85 and a second ring block 86 are slidably connected to the surface of the chute 833. A plurality of supports 851 are fixedly connected to the interiors of the first ring block 85 and the second ring block 86. Bushing 852 is fixedly installed at the end of each of the plurality of supports 851. The two bushings 852 are both threadedly connected to the surface of the bidirectional lead screw 84. A plurality of first fixing strips 821 are fixedly installed on the surface of the first ring block 85, and a plurality of second fixing strips 822 are fixedly installed on the surface of the second ring block 86. The first fixing strips 821 on the surface of the first ring block 85 are movably engaged with the first fixing strips 821 on the surface of the first turntable 82, and the second fixing strips 822 on the surface of the second ring block 86 are movably engaged with the second fixing strips 822 on the surface of the first turntable 82. The two bushings 852 are both slidably connected to the interior of the bushing groove 8311, and the plurality of supports 851 are all slidably connected to the interior of the support groove 8312.

[0061] Further in this embodiment, the setting of the chute 833 facilitates the movement of the first ring block 85 and the second ring block 86. In the initial state, the first fixing strips 821 on the surface of the first turntable 82 are engaged with the first fixing strips 821 on the surface of the first ring block 85. At this time, the pushing distance of the wire is shorter, and the cutting knife 93 can cut a shorter length of wire. When it is necessary to cut wires of different lengths, the bidirectional lead screw 84 is rotated by the turntable 841, and the two bushings 852 approach each other, causing the first ring block 85 and the second ring block 86 to fit together. At this time, the first fixing strips 821 on the surface of the first ring block 85 are separated from the first fixing strips 821 on the surface of the first turntable 82, and the second fixing strips 822 on the surface of the second ring block 86 are engaged with the second fixing strips 822 on the surface of the second turntable 832, and the pushing distance of the wire is longer, and the cutting knife 93 can cut a longer length of wire.

[0062] As Figure 2 and Figure 6 shown, the cutting mechanism 9 includes a reciprocating lead screw 91. A connecting plate 94 is fixedly connected to the interior of the support frame 62. The reciprocating lead screw 91 is rotatably connected to the surface of the connecting plate 94. A driven sprocket 911 is fixedly installed at the end of the reciprocating lead screw 91. A chain 722 is engaged with the surfaces of the driving sprocket 721 and the driven sprocket 911. A moving frame 92 is threadedly connected to the surface of the reciprocating lead screw 91, and a cutting knife 93 is fixedly installed inside the moving frame 92.

[0063] Further in this embodiment, when the transmission rod 72 rotates, the driving sprocket 721 rotates. Through the meshing of the driving sprocket 721, the driven sprocket 911 and the chain 722, the reciprocating lead screw 91 can rotate, and the moving frame 92 drives the cutting knife 93 to move downward to cut the wire, realizing equidistant cutting of wires with different lengths. The connecting plate 94 supports the wire, facilitating cutting.

[0064] The working principle of this embodiment is as follows. Before the wire drawing work starts, the appropriate die 43 is selected by rotating the mounting table 41. Through the cooperation of the bolt 13 with the screw hole 432 inside the die 43, the mounting table 41 and the fixed table 44, the die 43 is fixed inside the mounting groove 42, and at the same time, the mounting table 41 is fixed inside the fixed table 44. After the die 43 and the protective cover 31 are on the same horizontal plane, the plastic raw material is conveyed into the extruder 3 through the feed pipe 2 for wire drawing work. After the wire is made, it moves out from the through hole 412 and is in a high-temperature state. At this time, the cooling water in the cold water tank 51 sprays the wire through the nozzle 53 to realize the cooling treatment of the wire. The cooling water tank 6 performs secondary cooling on the wire and cleans the surface of the wire. A guide roller 61 is located inside the cooling water tank 6 to enable the wire to move inside the cooling water tank 6. Another guide roller 61 is higher than the cooling water tank 6 to convey the wire to the propulsion mechanism 8. The motor 71 is started, and the transmission rod 72 drives the large bevel gear 73 to rotate. Through the meshing relationship between the large bevel gear 73 and the small bevel gear 811, the small bevel gear 811 rotates. The small bevel gear 811 drives the rotating rod 81 to rotate. When the rotating rod 81 rotates, it drives the first turntable 82 to rotate. When the first turntable 82 rotates, through the meshing of the first fixing strip 821 on the surface of the first turntable 82 with the first fixing strip 821 on the surface of the first ring block 85 or the meshing of the second fixing strip 822 with the second fixing strip 822 on the surface of the second ring block 86, the second turntable 832 can rotate. The wire is located between the second turntable 832 and the third turntable 871. When the second turntable 832 rotates, it cooperates with the third turntable 871 to realize the propulsion of the wire. At the same time, through the meshing of the driving sprocket 721, the driven sprocket 911 and the chain 722, the reciprocating lead screw 91 can rotate, and the moving frame 92 drives the cutting knife 93 to move downward to cut the wire, realizing equidistant cutting of wires with different lengths.

[0065] The above is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
