DETAILED DESCRIPTION

[0036] The following is combined with Figure 1 -Attached Fig.15 , further details of this application are given.

[0037] Reference Figure 1 , Figure 2, a loading and unloading integrated machine for sealing ring production, comprising a coil support frame 1, a coil conveying assembly 2 is arranged on one side of the coil support frame 1, a coil cutting device 3 is arranged on the side of the coil conveying assembly 2 away from the coil support frame 1, and a rubber strip loading platform 4 is arranged on the side of the coil cutting device 3 away from the coil conveying assembly 2; a positioning conveyor belt 5 is arranged on the lower side of the rubber strip loading platform 4; a material guide assembly 6 is arranged between the rubber strip loading platform 4 and the positioning conveyor belt 5, a rubber strip handling assembly 7 is arranged above the positioning conveyor belt 5, and a sealing ring die-casting mold 8 is arranged on the side of the positioning conveyor belt 5 away from the rubber strip loading platform 4; a turnover control assembly 9 for controlling the turnover of the rubber strip loading platform 4 is installed on the coil cutting device 3 and the rubber strip loading platform 4; the rubber strip handling assembly 7 is used to transfer the rubber strip to the sealing ring die-casting mold 8; a grid measuring component 43 is used to control the action of the coil conveying assembly 2 and the coil cutting device 3;

[0038] The rubber coil is placed on the coil support frame 1, and the rubber coil is pulled by the coil conveying component 2 to be conveyed to the rubber strip loading platform 4. The length of the rubber strip is measured by the grid measuring piece 43 to control the coil cutting device 3 to cut it, and at the same time, the coil conveying component 2 is controlled to stop conveying, thereby reducing the error of the width of the cut rubber strip.

[0039] The cut rubber strips are placed on the positioning conveyor belt 5 through the material guide assembly 6, which reduces the height of the rubber strips falling, so that the rubber strips are placed on the positioning conveyor belt 5 more neatly;

[0040] When the rubber strips are placed on the equal-position conveyor belt 5 at equal distances, they are transported to the sealing ring die-casting mold 8 through the rubber strip transport component 7 and installed;

[0041] The rubber strip loading platform 4 is flipped by the roll material cutting device 3 and the flip control component 9 on the rubber strip loading platform 4, so that the rubber strip loading platform 4 flips once after each cutting, and the material guide component 6 completes one delivery, which can effectively prevent the rubber strip from getting stuck in the material guide component 6.

[0042] Reference Figure 2The coil cutting device 3 includes a cutting stage 31, a lower cutting knife 32 fixed on the cutting stage 31 near the side of the rubber strip stage 4, a cutting support platform 33 arranged above the cutting stage 31, a cutting cylinder 34 fixed on the cutting support platform 33, and a lower pressing plate 35 fixed at the lower end of the cutting cylinder 34; an upper cutting knife 36 is fixed on the lower pressing plate 35; a clamping assembly 37 is installed on the lower pressing plate 35; the lower side of the clamping assembly 37 is slightly lower than the lowermost end of the upper cutting knife 36. When cutting the rubber coil, the cutting cylinder 34 controls the lower pressing plate 35 to move downward, and the clamping assembly 37 first contacts the rubber coil to press the rubber coil on the cutting stage 31, and then the upper cutting knife 36 and the lower cutting knife 32 form a shear force to cut the coil into rubber strips; the rubber strips are placed on the rubber strip stage 4; thereby, the displacement of the rubber coil during the cutting process can be reduced, thereby effectively reducing the error of the rubber strip during the cutting process;

[0043] Reference Figure 2 , Figure 3 , Figure 4 , transmission shafts 41 are installed on both sides of the rubber strip stage 4; a loading support frame 42 is installed on both sides of the rubber strip stage 4; the transmission shaft 41 is rotatably connected with the loading support frame 42; the flip control assembly 9 includes a ratchet 91 fixed on the transmission shaft 41; a gear ring 92 is installed on the ratchet 91, and racks 93 are fixed at both ends of the lower pressure plate 35; the rack 93 is meshed with the gear ring 92;

[0044] When the lower pressing plate 35 moves downward, the rack 93 meshes with the toothed ring 92, and the toothed ring 92 rotates under the action of the ratchet 91. At this time, the rubber strip carrier 4 does not flip over. When the upper cutting knife 36 and the lower cutting knife 32 complete cutting, the lower pressing plate 35 moves upward. At this time, the rubber strip carrier 4 is flipped under the action of the rack 93, the toothed ring 92 and the ratchet 91; the displacement distance of the rack 93 is equal to the circumference of the toothed ring 92, so that the rubber strip carrier 4 completes a 360-degree flip;

[0045] The rubber strip loading platform 4 does not flip over during the process of the upper cutting knife 36 and the lower cutting knife 32 completing the cutting, so that the rubber strip is stably placed on the rubber strip loading platform 4;

[0046] Reference Figure 2 A stepping gear 44 is mounted on the transmission shaft 41; the stepping gear 44 drives the positioning conveyor belt 5 to rotate step by step through the driving chain 47;

[0047] The rubber strip loading platform 4 turns over once, and the stepping gear 44 rotates one circle, driving the positioning conveyor belt 5 to rotate through the driving chain 47, so that the positioning conveyor belt 5 rotates the same distance each time, so that the rubber strips are placed on the positioning conveyor belt 5 at equal distances.

[0048] Reference Figure 5The clamping assembly 37 includes a pressing sliding rod 371 slidably mounted on the lower pressing plate 35; a pressing plate 372 is fixed at the lower end of the pressing sliding rod 371; a pressing spring 373 is sleeved on the pressing sliding rod 371; one end of the pressing spring 373 abuts against the lower pressing plate 35, and the other end abuts against the pressing plate 372; a locking hoop 374 is detachably mounted on the pressing sliding rod 371; during the pressing process of the pressing assembly 37, after the pressing plate 372 contacts the rubber coil, the cutting cylinder 34 continues to move downward, and the rubber coil is pressed down under the action of the pressing sliding rod 371 and the pressing spring 373; the telescopic length of the pressing sliding rod 371 can be controlled by adjusting the position of the locking hoop 374, and at the same time, the pressing assembly 37 can be prevented from separating from the lower pressing plate 35 under the action of the locking hoop 374.

[0049] Reference Figure 6 , Figure 7 The positioning conveyor belt 5 includes a conveying support frame 51, and conveying shafts 52 are installed at both ends of the conveying support frame 51. Conveying rollers 53 are fixed on the conveying shafts 52. Conveying belts 54 are sleeved on the conveying rollers 53, and limiting strips 55 are fixed at equal intervals on the conveying belts 54; driven gears 56 are fixed at both ends of the conveying shafts 52; the driven gears 56 are connected to the driving chain 47; each time the rubber strip loading platform 4 is flipped, the stepping gear 44 rotates one circle, and the driving chain 47 acts on the driven gear 56 at the same angle each time, so the conveying belt 54 is displaced the same each time, so that the distance between the rubber strips put by the material guide component 6 on the conveying belt 54 is equal;

[0050] The cross section of the limiting strip 55 is a trapezoidal structure that is smaller at the top and larger at the bottom, so a trapezoidal groove is formed on the upper side of the conveyor belt 54 , and the rubber strip placed on the conveyor belt 54 is accurately positioned by the trapezoidal groove.

[0051] Reference Figure 2 , Figure 5 A positioning turntable 45 is fixed on the transmission shaft 41, and a counterweight 46 is arranged on the positioning turntable 45; the counterweight 46 is connected to the positioning turntable 45 by a traction rope; the counterweight 46 is used to make the side of the rubber strip stage 4 on which the grid measuring piece 43 is installed face upward; the gravity of the counterweight 46 is greater than the deflection force of the rubber strip stage 4;

[0052] Because the rubber strip carrier 4 can rotate unidirectionally under the action of the ratchet 91, the rack 93 and the gear ring 92, the rubber strip carrier 4 is a flat structure, and due to its own structural reasons, it will generate deflection force and cannot ensure that the plane is facing upward. By installing a turntable 45 on the transmission shaft 41, and connecting the counterweight 46 to the turntable 45 through a traction rope, the gravity generated by the counterweight 46 is perpendicular to one side of the plane of the rubber strip carrier 4. When the plane of the rubber strip carrier 4 is facing upward, the directions of the forces of the traction rope, the counterweight 46 and the transmission shaft 41 are in the same straight line. When the angle of the rubber strip carrier 4 is offset, the directions of the forces of the traction rope, the counterweight 46 and the transmission shaft 41 are not in the same straight line. Under the action of the counterweight 46, the directions of the forces of the traction rope, the counterweight 46 and the transmission shaft 41 are restored to the same straight line, thereby effectively preventing the rubber strip carrier 4 from deflecting and keeping the plane facing upward.

[0053] Reference Figure 3 , Figure 5 The material guiding assembly 6 includes a material receiving hopper 61 installed on the lower side of the rubber strip loading platform 4 and a material guiding channel 62 fixed at the lower end of the material receiving hopper 61; the lower end of the material guiding channel 62 is close to the upper side of the limiting strip 55; the distance between the lower end of the material guiding channel 62 and the upper side of the limiting strip 55 is less than the thickness of the rubber strip, and the distance between the lower end of the material guiding channel 62 and the upper side of the conveyor belt 54 is greater than the thickness of the rubber strip. During the rotation of the rubber strip loading platform 4, the cut rubber strip is placed on the conveyor belt 54, and when the groove is aligned with the material guiding channel 62, the rubber strip is accurately placed in the groove between the limiting strips 55, thereby further equidistantly arranging the rubber strips.

[0054] Reference Figure 8 , Fig. 9 The rubber strip transport assembly 7 includes a transport bracket 71, a moving platform 72 is installed on the upper end of the transport bracket 71, a lifting cylinder 73 is installed on the moving platform 72, a needle plate 74 is fixed on the lower end of the lifting cylinder 73, a push plate 75 is installed on the lower side of the needle plate 74, and the push plate 75 is connected to the needle plate 74 through a push cylinder 76;

[0055] When the rubber strip is transferred, the lifting cylinder 73 controls the needle plate 74 to move downward, and the pushing cylinder 76 controls the push plate 75 to move upward, so that the needles on the lower side of the needle plate 74 are exposed, so that the needles pierce the rubber strip and fix the rubber strip on the needle plate 74, so that the position of the rubber strip does not change significantly, so that the rubber strip can be placed on the mold at an equal distance;

[0056] Moving gears 721 are installed on both sides of the moving platform 72; a tooth groove 722 meshing with the moving gear 721 is installed on the upper end of the transport bracket 71; a moving motor 723 is installed on the transport bracket 71; a moving screw 724 is fixed to the output end of the moving motor 723; a moving sleeve 725 threadedly connected to the moving screw 724 is installed on the moving platform 72; the displacement error can be reduced by the cooperation between the moving screw 724 and the moving sleeve 725;

[0057] The moving motor 723 drives the moving screw 724 to rotate and control the displacement of the moving platform 72. When the moving platform 72 moves to the top of the sealing ring die-casting mold 8, the lifting cylinder 73 controls the needle plate 74 to move downward so that the rubber strip stuck on the needle plate 74 fits with the sealing ring die-casting mold 8. At this time, the moving cylinder 76 controls the push plate 75 to move downward so that the rubber strip is placed on the sealing ring die-casting mold 8. During the transfer of the rubber strips, the distance between the rubber strips does not change significantly, so that the rubber strips can be placed equidistantly on the sealing ring die-casting mold 8, thereby reducing the use of manual labor and improving production efficiency.

[0058] Moving gears 721 are installed on both sides of the moving platform 72; a tooth groove 722 meshing with the moving gear 721 is installed on the upper end of the transport bracket 71. With the cooperation of the moving gear 721 and the tooth groove 722, the error caused by the displacement of the moving platform 72 due to inertia during the movement process can be reduced, thereby making the error smaller when the rubber strip is placed on the sealing ring die-casting mold 8.

[0061] During the loading process of the rubber coil, the coil support rod 15 is placed on the U-shaped bearing portion 14, and the coil conveying assembly 2 pulls the coil to complete the conveying of the rubber coil;

[0062] During the process of loading the rubber coil, a new rubber coil can be installed on the U-shaped bearing portion 14 on the side of the trapezoidal loading platform 13 away from the coil conveying assembly 2. After the rubber coil on the side close to the coil conveying assembly 2 is delivered, the pin 18 is pulled out, and after the rotating platform 12 is rotated 180 degrees, the new coil is connected to the coil conveying assembly 2 by locking the pin again. During the process of loading the coil support frame 1, the coil can be installed on the trapezoidal loading platform 13, thereby improving the efficiency of the rubber coil replacement.

[0063] A bearing 16 is installed on the coil support rod 15 , and the bearing 16 is clamped on the U-shaped bearing portion 14 , so as to reduce the resistance of the coil support rod 15 and make the rubber coil conveying smoother.

[0065] When placing the rubber strip on the sealing ring die-casting mold 8, the mold pulling component 86 controls the lower mold 82 to move to the empty position of the sealing ring die-casting frame 81. After the rubber strip conveying component 7 places the rubber strip on the lower mold 82 at equal intervals, the mold pulling component 86 controls the lower mold 82 to move to just below the upper mold 85. After the upper mold 85 is aligned with the lower mold 82, the lifting component 84 controls the upper mold 85 to move downward, so that the upper mold 85 and the lower mold 82 are accurately matched. After heating and pressurizing, the rubber is melted to form a semi-finished sealing ring. After the semi-finished sealing ring is taken off and processed, it forms a sealing ring.

When the limit member 88 retracts into the groove, the mold flipping motor 87 can control the flipping of the lower mold 82. The unloading is completed; when the mold flipping motor 87 controls the lower mold 82 to be in a horizontal state, the limit cylinder 89 controls the limit member 88 to extend out of the groove. At this time, the mold traction assembly 86 controls the sliding platform 80 to move to the bottom of the upper mold 85. After the upper mold 85 is aligned with the lower mold 82, the lifting member 84 controls the lifting platform 83 to move downward, so that the upper mold 85 and the lower mold 82 are accurately matched. After heating and pressurizing, the rubber is melted to form a semi-finished sealing ring. After the semi-finished sealing ring is taken down and processed, it forms a sealing ring;
