Description

Technical Field

[0001] This application relates to the field of sealing strip manufacturing technology, and in particular to a sealing strip edge cutting machine. Background Technology

[0002] Sealing strips are rubber strips used for sealing products. They are also strip-shaped rubber materials used on the surfaces of vehicles, buildings, etc. They have good elasticity and softness and are mainly used in gaps in the body, cab, passenger compartment and undercarriage of automobiles, such as door frames and windows. They have good mechanical properties, high elasticity, low cross-sectional shrinkage and dimensional stability.

[0003] During the production of sealing strips, processes such as melting, shaping, and trimming are required to produce the sealing strips. After the strips are formed, they need to be trimmed and edged by equipment to finish them, which is the final process before the strips leave the factory.

[0004] Most existing edge-cutting machines first fix the rubber strip, and then cut the fixed rubber strip through a cutting mechanism to perform edge-cutting processing. However, when cutting the rubber strip, because the rubber strip material has strong elasticity, burrs are easy to appear at the cut after cutting, which affects the production quality of the rubber strip. Utility Model Content

[0005] The purpose of this application is to solve the problem in the above-mentioned background technology that when cutting the edge of the rubber strip, burrs are easily generated at the cut edge due to the strong elasticity of the rubber strip material, which affects the production quality of the rubber strip. This application provides a sealing rubber strip edge cutting machine.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution:

[0007] A sealing strip trimming machine includes a worktable, an L-shaped support plate fixedly connected to one top end of the worktable, an adjusting platform fixedly connected to one side of the worktable, a rubber conveyor belt fixedly connected to one side of the top of the worktable, a waste bin placed on the other side of the top of the worktable, a cutting table fixedly connected to one side of the rubber conveyor belt, a pressure roller fixedly connected to the top of the L-shaped support plate, a cutting component fixedly connected to one side of the top of the L-shaped support plate, an adjusting component installed on the adjusting platform, a grinding component fixedly connected to one side of the waste bin, a material extraction component fixedly connected to one side of the waste bin, the extraction end of the material extraction component installed outside the output end of the grinding component, and a collection box placed on one side of the adjusting platform.

[0008] By adopting the above technical solution, after the cutting part cuts the edge of the sealing strip, the sealing strip is conveyed by a rubber conveyor belt, and the cut edge of the sealing strip is conveyed to the edge grinding part. Through the operation of the edge grinding part, the internal components of the edge grinding part grind the cut edge of the strip, thereby removing the burrs at the cut edge, thus improving the quality of the edge cutting of the sealing strip and thus improving the production quality of the sealing strip.

[0009] Furthermore, a measuring ruler is fixedly connected to one side of the adjustment platform.

[0010] By adopting the above technical solution, the sealing strip can be measured using a measuring tape and adjusting components.

[0011] Furthermore, the adjustment platform is provided with a sliding groove, and the adjustment component includes a screw rotatably connected inside the sliding groove. One end of the screw is fixedly connected to a handle, and a drive block is threadedly connected to the screw. A limit plate is fixedly connected to the top of the drive block.

[0012] By adopting the above technical solution, rotating the handle can drive the screw to rotate, thereby driving the limiting plate and adjusting the position of the limiting plate.

[0013] Furthermore, the grinding component includes a motor fixedly connected to one side of the top of the waste bin, the output end of the motor being fixedly connected to a rotating shaft, and one end of the rotating shaft being fixedly connected to a grinding disc.

[0014] By adopting the above technical solution, the sealing sleeve is ground by grinding with a grinding disc.

[0015] Furthermore, the material extraction component includes an air pump fixedly connected to one side of the waste bin, a conveying hose fixedly connected to the extraction end of the air pump, a connecting pipe fixedly connected to one end of the conveying hose, a material separator hood connected to the connecting pipe, and the rotating shaft being connected through the material separator hood.

[0016] By adopting the above technical solution, under the operation of the air pump, the material separator can be evacuated through the delivery hose and connecting pipe, so that a negative pressure is formed inside the material separator, thereby removing the fine burrs generated by the grinding.

[0017] Furthermore, a filter screen box is placed on one side of the waste bin, and the discharge end of the air pump is located inside the filter screen box.

[0018] By adopting the above technical solution, fine burrs are blocked by the filter screen box, thereby storing the fine burrs in the waste bin.

[0019] Furthermore, the pressure roller component includes an electric push rod two fixedly connected to the top of the L-shaped support plate. One end of the electric push rod two is fixedly connected to a connecting box, and the bottom of the connecting box is rotatably connected to multiple rollers, which are located directly above the rubber conveyor belt.

[0020] By adopting the above technical solution, the sealing strip is pressed and squeezed by rollers, thereby squeezing and fixing the sealing strip.

[0021] Furthermore, the cutting component includes an electric push rod fixedly connected to one side of the top of the L-shaped support plate, one end of the electric push rod being fixedly connected to a connecting plate, and the bottom of the connecting plate being fixedly connected to a cutting blade.

[0023] In summary, this application includes at least one of the following beneficial effects;

[0024] 1.

Through the operation of the edge grinding part, the internal components of the edge grinding part grind the edge of the sealing strip, thereby removing the burrs at the edge and improving the quality of the edge cutting of the sealing strip, thus improving the production quality of the sealing strip.

[0036] The following is in conjunction with the appendix Figure 1 —8 provides further details regarding this application.

[0037] This application discloses a sealing strip trimming machine.

[0038] Reference Figure 1 , Figure 2 and Figure 3 A sealing strip trimming machine includes a workbench 1, an L-shaped support plate 2 fixedly connected to one top end of the workbench 1, an adjusting table 7 fixedly connected to one side of the workbench 1, a rubber conveyor belt 3 fixedly connected to one side of the top of the workbench 1, a waste bin 4 placed on the other side of the top of the workbench 1, a cutting table 31 fixedly connected to one side of the rubber conveyor belt 3, a pressure roller 6 fixedly connected to the top of the L-shaped support plate 2, a cutting piece 5 fixedly connected to one side of the top of the L-shaped support plate 2, an adjusting piece 8 installed on the adjusting table 7, a grinding piece 9 fixedly connected to one side of the waste bin 4, a material extraction piece 10 fixedly connected to one side of the waste bin 4, the extraction end of the material extraction piece 10 being installed outside the output end of the grinding piece 9, a collection box 11 placed on one side of the adjusting table 7, and a measuring ruler 72 fixedly connected to one side of the adjusting table 7.

[0039] When producing the sealing strip by trimming, the adjusting component 8 can be manually operated first to make its internal components move, allowing people to adjust the size of the sealing strip to be retained. Here, the measuring ruler 72 can be used in conjunction with the adjusting component 8 to measure the sealing strip, thereby improving the accuracy of the retained size. Then, the edge of the sealing strip is placed against the adjusting component 8, and the other side is placed on the rubber conveyor belt 3. Through the operation of the pressure roller 6, the pressure roller 6 squeezes and fixes the sealing strip at the rubber conveyor belt 3. After fixing, the internal components of the cutting component 5, in conjunction with the cutting table 31, are used to trim the sealing strip. The cut waste material can fall naturally into the waste bin 4 for storage, so that the waste material can be centrally processed.

[0040] After the sealing strip is trimmed, the pressure roller 6 continues to squeeze the sealing strip. At this time, the operation of the rubber conveyor belt 3 can cooperate with the pressure roller 6 to clamp and move the strip, thereby driving the trimmed edge of the strip towards the grinding edge 9. Through the operation of the grinding edge 9, the trimmed edge of the strip can be ground, thereby removing the burrs generated during cutting and improving the trimming quality of the strip. After grinding, the continuous operation of the rubber conveyor belt 3 causes the strip to break free from the pressure of the pressure roller 6, allowing the ground strip to fall naturally into the collection box 11. The collection box 11 collects the trimmed strip. During the grinding process, large burrs can fall naturally into the waste bin 4, while small debris can be drawn into the waste bin 4 by the operation of the material extractor 10, thereby reducing the possibility of debris splashing during grinding and reducing the possibility of debris splashing out.

[0041] Reference Figure 3 The adjusting table 7 has a slide groove 71. The adjusting component 8 includes a screw 82 rotatably connected inside the slide groove 71. One end of the screw 82 is fixedly connected to a handle 81. A drive block 83 is threadedly connected to the screw 82. A limit plate 84 is fixedly connected to the top of the drive block 83.

[0042] Rotating the handle 81 under the action of force can drive the screw 82 to rotate. The rotating screw 82 can drive the drive block 83, causing the drive block 83 to move inside the slide groove 71, thereby driving the limit plate 84 to move. This allows for position adjustment of the limit plate 84 and adjustment of the retention size of the sealing strip according to the measuring scale 72, thereby improving the cutting accuracy.

[0043] Reference Figure 4 The grinding component 9 includes a motor 91 fixedly connected to one side of the top of the waste bin 4. The output end of the motor 91 is fixedly connected to a rotating shaft 92, and one end of the rotating shaft 92 is fixedly connected to a grinding disc 93.

[0044] When the motor 91 is running, it can drive the rotating shaft 92 to rotate. The rotating shaft 92 can drive the grinding disc 93 to rotate, and the rotating grinding disc 93 can perform edge grinding on the sealing sleeve.

[0045] Reference Figure 5 and Figure 6 The material extraction component 10 includes an air pump 101 fixedly connected to one side of the waste bin 4. The extraction end of the air pump 101 is fixedly connected to a conveying hose 102. One end of the conveying hose 102 is fixedly connected to a connecting pipe 103. A material separator 104 is connected to the connecting pipe 103. The rotating shaft 92 is connected through the material separator 104. A filter screen box 41 is placed on one side of the waste bin 4. The discharge end of the air pump 101 is located inside the filter screen box 41.

[0046] When the grinding disc 93 grinds the edge, the burrs removed by the material separator 104 can be blocked, reducing the possibility of burrs flying. The material separator 104 can block the burrs and allow them to fall naturally into the waste bin 4. Under the operation of the vacuum pump 101, the material separator 104 can be evacuated through the conveying hose 102 and the connecting pipe 103, so that the material separator 104 is negatively pressured. This allows the fine burrs generated by the grinding to be extracted and drawn into the waste bin 4 through the connecting pipe 103 and the conveying hose 102. The filter screen box 41 blocks the fine burrs, thus storing them in the waste bin 4.

[0047] Reference Figure 7 The pressure roller component 6 includes an electric push rod 61 fixedly connected to the top of the L-shaped support plate 2. One end of the electric push rod 61 is fixedly connected to a connecting box 62. Multiple rollers 63 are rotatably connected to the bottom of the connecting box 62. The rollers 63 are located directly above the rubber conveyor belt 3.

[0048] When the electric actuator 61 operates, it can drive the connecting box 62 to move towards the rubber conveyor belt 3, and drive multiple rollers 63 to press and squeeze the sealing strip, thereby squeezing and fixing the sealing strip and pressing the edge of the strip. When the rubber conveyor belt 3 is running, the rollers 63 can cooperate with the rubber conveyor belt 3 to move the sealing strip, thereby clamping and conveying the strip.

[0049] Reference Figure 8 The cutting component 5 includes an electric push rod 51 fixedly connected to one side of the top of the L-shaped support plate 2. One end of the electric push rod 51 is fixedly connected to a connecting plate 52, and the bottom of the connecting plate 52 is fixedly connected to a cutting blade 53.

[0050] When the electric actuator 51 is in operation, the connecting plate 52 can be pressed down, which in turn drives the cutting blade 53 to move. The cutting blade 53, which moves down, can work with the cutting table 31 to cut the edge of the rubber strip.

[0051] Working principle: When the sealing strip is being trimmed, the handle 81 can be rotated under force, which drives the screw 82 to rotate. The rotating screw 82 drives the drive block 83, causing the drive block 83 to move inside the slide groove 71, thereby moving the limiting plate 84 and adjusting its position. Here, the measuring ruler 72 can be used in conjunction with the adjusting component 8 to measure the sealing strip, thereby improving the accuracy of the retained dimensions. Afterwards, the edge of the sealing strip is placed against the adjusting component 8, and the other side is placed on the rubber... On the conveyor belt 3, the operation of the electric push rod 61 can drive the connecting box 62 to move towards the rubber conveyor belt 3, and drive multiple rollers 63 to press and squeeze the sealing strip. After fixing, the operation of the electric push rod 51 can drive the connecting plate 52 to press down, which in turn drives the cutting blade 53 to move. The downward cutting blade 53, in conjunction with the cutting table 31, can trim the edge of the rubber strip. The cut waste can fall naturally into the waste bin 4 for storage, so that people can centrally process the waste.

[0052] After the sealing strip is trimmed, the pressure roller 6 continues to compress it. Meanwhile, the rubber conveyor belt 3, in conjunction with the pressure roller 6, clamps and moves the strip, causing the trimmed edge to move towards the grinding edge 9. The motor 91 drives the rotating shaft 92 to rotate, which in turn drives the grinding disc 93. The rotating disc 93 then grinds the edge of the sealing sleeve, removing the burrs generated during trimming. The process improves the edge quality of the rubber strip. After grinding, the rubber strip is released from the pressure roller 6 by the continuous operation of the rubber conveyor belt 3, and the ground rubber strip falls naturally into the collection box 11. The collection box 11 collects and processes the ground rubber strip. During the grinding process, large burrs can fall naturally into the waste box 4, while small debris can be drawn into the waste box 4 by the operation of the material extraction component 10. This reduces the possibility of debris splashing during the grinding process.
