[0031] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.
[0032] A strapping tape recycling roller shearing mechanism includes a recycling feeding mechanism, a power mechanism, and auxiliary devices. The recycling feeding mechanism includes a clamping cylinder 1, an upper roller assembly 2, and a lower roller 3. The power mechanism includes a motor 4. The auxiliary devices include a frame 5 and a synchronous belt 6. The recycling feeding mechanism is responsible for continuously conveying the strapping tape, the power mechanism is responsible for providing power to the recycling feeding mechanism, and the auxiliary devices are responsible for connecting the motor 2 and the recycling feeding mechanism, transmitting power to the recycling feeding mechanism.
[0033] Optionally, the clamping cylinder 1 of the recycling feeding mechanism is fixedly mounted on the frame 5, the upper roller assembly 2 of the recycling feeding mechanism is mounted on the lower part of the push rod of the clamping cylinder 1, the lower roller 3 of the recycling feeding mechanism is fixedly mounted on the frame 5 and driven to rotate by the motor 4, and the vertical movement of the upper roller assembly 2 is driven by the clamping cylinder 1.
[0034] Optionally, the upper roller assembly 2 includes at least a connecting bracket 21, spring a 221, spring b 222, upper roller 23, upper roller shaft 24, bearing 25, left and right limiting blocks, limiting plate 27, roller rear support 28, and roller front support 29; the connecting bracket 21 is fixedly connected to the clamping cylinder 1, and the connecting bracket 21 is fixedly connected to the roller front support 29 and roller rear support 28 by fixing bolts; the upper roller shaft 24 is connected to the upper roller 23 by the bearing 25; the upper roller shaft 24 can move up and down in the middle hole of the roller front support 29 and roller rear support 28 under the drive of the upper roller 23; the main body of spring a 221 is located in front of the roller. Inside the bracket 29, the main body of the spring b222 is located inside the rear bracket 28 of the roller. This structure can prevent the spring from slipping and swinging. One end of each of the two springs is connected to the connecting bracket 21, and the other end is connected to the roller shaft 24. The upper roller 23 floats up and down according to the thickness of the packing strap under the action of the spring. The front bracket 29 of the roller is connected to the left and right limiting blocks 26 and the limiting plate 27 by bolts. A gap is left between the left and right limiting blocks 26 and the outer circle of the upper roller 23 so that the packing strap cannot pass through, ensuring the smooth operation of the upper roller and preventing the packing strap from being caught in the upper roller. The limiting plate 27 is in a closed state with the frame 5 during the operation of the mechanism to prevent the packing strap from swinging and falling off the roller.
[0035] The length of the spring changes with the thickness of the strapping, ensuring that the strapping and the heat-fused double-layer joint can pass smoothly through the recycling feeding mechanism and avoid jamming. The upper roller has a grooved surface to ensure friction, preventing the strapping from slipping through the recycling feeding mechanism. At the same time, this grooved surface structure, combined with the spring's squeezing force, can also provide an elastic rolling effect on the strapping, effectively rolling (flattening) some bent areas of the used strapping to ensure smooth conveying and provide a guarantee for subsequent shearing.
[0036] The gap between the left and right limiting blocks and the upper roller prevents the strapping from getting caught in the roller during the recycling process, thus avoiding recycling failure due to equipment downtime. The limiting plate is in a closed state with the frame during the operation of the mechanism to prevent the strapping from swinging and deviating. Under the restriction of the limiting blocks, the strapping will smoothly enter the recycling and cutting mechanism.
[0037] In use, the pressing cylinder 1 drives the upper roller assembly 2 to move downward, and the upper roller assembly 2 presses down on the packing strap. Under the action of the spring, the upper roller 23 will move up and down according to the thickness of the packing strap to ensure sufficient pressure on the packing strap. At this time, the lower roller 3 starts to rotate under the drive of the motor, and the packing strap is transported out of the recycling feeding mechanism by the rolling of the upper roller and the lower roller.
[0038] Optionally, the power mechanism motor 4 is fixedly mounted on the frame 5, and the motor 4 drives the lower roller 3 of the recycling feeding mechanism to rotate synchronously through the synchronous belt 6 of the auxiliary device; during recycling feeding, the lower roller 3 drives the upper roller 23 of the recycling feeding mechanism to rotate through friction.
[0039] Optionally, after the strapping enters the equipment, the upper roller assembly 2 of the recycling feeding mechanism presses the strapping downwards by the pressing cylinder 1 of the recycling feeding mechanism, and the motor 4 of the power mechanism drives the lower roller 3 to rotate through the synchronous belt 6. Under the action of the upper and lower rollers, the strapping is gradually fed out.
[0040] Optionally, a recycling shearing mechanism is also included, which includes a tape-cutting cylinder 9, a cutter assembly, and a guide seat 72; the recycling feeding mechanism is responsible for continuously feeding the packing tape to the recycling shearing mechanism, and the recycling shearing mechanism is responsible for segmenting and cutting the packing tape.
[0041] Optionally, the left and right limiting blocks 26 and the frame 5 form a packing tape conveyor 8, and the recycling shearing mechanism is provided on one side of the conveyor 8.
[0042] Optionally, a guide partition 81 is provided between the conveyor 8 and the recycling shearing mechanism, and a packing strap guide 82 is provided on the guide partition 81 corresponding to the conveyor 8; the cutter assembly is provided on one side of the packing strap guide 82; the cutter assembly includes an upper blade 7 and a lower blade 71; the upper blade 7 is driven to move up and down by a cutting cylinder 9. The limiting piece 27 extends from the left and right limiting blocks 26 to the guide seat 72 to maintain the limiting of the packing strap until the shearing is completed.
[0043] The beneficial effects of adopting the above scheme are as follows:
[0044] By using the compression of the upper roller assembly 2 and the lower roller 3, the packing strap is elastically clamped and conveyed, which improves the conveying effect and prevents the strap from jamming. At the same time, the elastic compression has a roller pressing effect on the conveyed packing strap. For a bent section of packing strap, it can be roller pressed flat. As for the double-layer packing strap phenomenon at the knot connection, if the compression force is too large, the spring will contract and will not affect the normal transmission of the packing strap.
[0045] The set-up conveyor 8 and packing tape guide 82, such as Figures 5-7As shown, this is mainly to control the stress that may occur on the packing strap during the above process, and to effectively limit the space of the packing strap, preventing it from warping or deviating due to high stress during the process, thus affecting the subsequent shearing effect.
[0046] Optionally, the guide seat 72 is also included, which is provided with a guide groove for guiding the upper blade 7.
[0047] This utility model solves the problems in the background technology, and its operating principle is as follows:
[0048] First, such as Figure 1 As shown, the strapping is fed in from the left side between the upper roller assembly 2 and the lower roller 3. After being elastically squeezed by the upper roller assembly 2 and rolled flat by the grooves on the surface of the upper roller 23, the strapping is flattened. Its front end is limited by the conveyor 8 and the strapping guide 82 and continues to be conveyed, effectively avoiding the strapping getting stuck in the rotating roller or curling. After being conveyed to the recycling shearing mechanism, the strapping is cut by the combination of the upper blade 7 and the lower blade 71 in an up-and-down motion, which significantly improves the shearing effect and prevents the strapping from curling and accumulating at the cutter due to continuous shearing and the continuous conveying of the strapping from the rear, thus preventing the equipment from jamming. The effect is good.
