Description

Technical Field

[0001] This utility model relates to the field of rubber strip conveying and cutting technology, specifically to a steel-headed rubber strip conveying and cutting device. Background Technology

[0002] During the processing of steel caps, adhesive strips are applied to the edges of the cap to improve its surface cushioning effect. The first step in applying the adhesive strips is conveying and cutting. The current conveying and cutting process is as follows: the adhesive strip passes sequentially through a meter counter, a limit wheel, a first conveyor wheel, a cutting device, and a second conveyor wheel. The first and second conveyor wheels are then driven by a motor to rotate synchronously, achieving continuous conveying of the adhesive strip through frictional traction. During this process, the meter counter rolls in contact with the adhesive strip surface via its built-in measuring wheel, calculating the conveying length in real time. When the preset length is reached, the cutting device is activated and cuts the adhesive strip, resulting in equal-length strip segments.

[0003] However, existing technologies have the following technical drawbacks in practical applications. Specifically, both the conveying and length measurement of the rubber strip rely on the friction between the conveying wheel and the measuring wheel of the meter counter and the surface of the rubber strip. Because the rubber strip material (such as rubber, silicone, etc.) often has smooth surfaces or high flexibility, it is prone to relative sliding with the wheel contact surface during conveying, leading to the following problems:

[0004] 1. Because the measuring wheel of the meter counter slips, the theoretical conveying length recorded by it will not match the actual length, resulting in poor consistency of the length of the cut rubber strip segments, which makes it difficult to meet the requirements of high-precision processing.

[0005] 2. Slippage between the conveyor wheel and the rubber strip may cause fluctuations in the conveying speed of the rubber strip, or even positional deviation, which will further exacerbate the decline in slitting quality and lead to a decrease in the product qualification rate.

[0039] By cooperating with the pressing screw 43 and the guide rod 44 in the second conveying assembly 4, the height of the conveying component 42 can be adjusted, thereby adjusting the distance between the first conveying assembly 3 and the conveying component 42, so as to convey rubber strips of different thicknesses in the later stage. Example 3

[0040] like Figures 1-8 As shown, based on the above embodiments, this embodiment further provides the following:

[0041] The feeding assembly 7 includes a feeding frame 71. The feeding frame 71 is installed on the top surface of the base plate 1. A second conveyor motor 72 is fixedly connected to one side of the feeding frame 71. The output shaft end of the second conveyor motor 72 is connected to a bolt shaft 73 through a worm gear and worm wheel. A stop plate 74 is fixedly connected to the surface of the bolt shaft 73. A protrusion 75 is fixedly connected to the surface of the bolt shaft 73 and to one side of the stop plate 74. A screwing disc 76 is threadedly connected to the surface of the bolt shaft 73.

[0042] The feeding assembly 7 enables the installation and removal of the rolled rubber strips, and also allows for the uniform release of the rubber strips when they are cut.

[0043] Working principle and usage process of this utility model:

[0044] In use:

[0045] First, install the rolled rubber strip. During installation, the worker first aligns the middle of the rubber strip roller with the bolt shaft 73 and inserts it. When inserting, it is also necessary to align the convex hole in the middle with the protrusion 75. After alignment, the rubber strip roller can be limited. After the rubber strip roller is inserted, it will contact the surface of the stop plate 74. At the same time, the screwing plate 76 is turned. By turning the screwing plate 76, the other side of the rubber strip roller can be limited.

[0046] After installation, the staff pulls one end of the rubber strip so that the rubber strip passes between the first conveying component 3 and the conveying component 42. After passing through, the other end of the rubber strip passes through the middle of the U-shaped limiting block 53. When passing through, it is also necessary to ensure that the rubber strip is below the arc-shaped lower pressure plate 55. At this time, the up, down, left and right limits of the rubber strip can be achieved by the arc-shaped lower pressure plate 55 and the U-shaped limiting block 53.

[0047] After passing through, the rubber strip will be located on the swing plate 63. At this time, the worker will rotate the limiting threaded rod 65 according to the required cutting length. As the limiting threaded rod 65 rotates, it will drive the blocking rod 66 to move. When the blocking rod moves to the designated position, it will stop moving.

[0048] At this time, rotate and press down the screw 43. When the screw 43 is working, it will drive the conveying component 42 to move downward under the action of the guide rod 44. As the conveying component 42 moves downward, the conveying component 42 and the first conveying assembly 3 can clamp the rubber strips of different thicknesses.

[0049] Start the second conveyor motor 72. The second conveyor motor 72 drives the bolt shaft 73, the stop plate 74 and the turning plate 76 to rotate, thereby driving the rubber strip roller to rotate and release the rubber strip.

[0050] When the rubber strip is released, the conveyor motor 35 in the conveyor component 42 and the first conveyor assembly 3 starts to work. When the conveyor motor 35 works, it will drive the two sets of conveyor belts 36 to rotate in opposite directions, thereby driving the rubber strip to move forward. At this time, the rubber strip in the U-shaped limit block 53 moves forward, so that the rubber strip moves on the swing plate 63. When one end of the rubber strip is about to contact the blocking rod 66, the pressing pneumatic rod 56 drives the pressing plate 57, the cutting knife 58 and the pressing rod 59 to move downward. When the cutting knife 58 moves downward, it will start to cut the rubber strip under the action of the knife groove 54. At this time, one end of the rubber strip will contact the blocking rod 66. When the rubber strip is cut, the pressing pneumatic rod 56 will drive the pressing plate 57 and the pressing rod 59 to continue to move downward, and start to squeeze the reset rack 69. The reset rack 69 drives the swing gear 67, the swing shaft 62 and the swing plate 63 to rotate, so that the cut rubber strip on the swing plate 63 falls down.

[0051] When the reset rack 69 is not in contact with the lower pressure rod 59, it will be reset under the action of the reset damping rod 68. After reset, it will drive the swing plate 63 to reset, which facilitates the cutting of the lower section of the rubber strip and also realizes the equal length cutting of the rubber strip.
