Description

Technical Field

[0001] This utility model relates to the field of packing strap removal, specifically to an automatic recycling and cutting device for packing straps. Background Technology

[0002] Packing straps are a type of composite material widely used for bundling boxes. They are typically made of materials such as polypropylene (PP), polyester (PET), paper tape, and nylon tape, and are commonly used in logistics, warehousing, manufacturing, electronics, and carton packaging. Since the packaging straps need to be disassembled before use, cutting and recycling them are crucial. In assembly lines, the speed of disassembly affects work efficiency. Some existing packing strap disassembly equipment does not cut the straps into sections, which hinders collection and subsequent recycling.

[0003] To address the issue of strapping recycling, an existing applicant has proposed a strapping fixed-length output cutting device that uses a roller-driven cutter for strapping recycling. However, the lack of a device to constrain the strapping makes it difficult for it to enter the cutter position, resulting in recycling failure. Furthermore, when the strapping completely passes through the roller and cannot be further conveyed to the cutter position, the accumulation of a large amount of end-of-stretch strapping leads to the inability to properly recycle subsequent strapping.

[0004] To address the issue of stripping and recycling of packing straps, existing recycling technologies have certain shortcomings. The packing straps are prone to misalignment, leading to recycling failures. When the packing straps are significantly bent, they may become uncut. Most existing packing strap recycling technologies are designed for single-layer packing straps. When dealing with the double or multiple layers of packing straps already used on packaging boxes, the recycling process can easily cause equipment jamming. Furthermore, the inability to remove the end of the packing straps can lead to its accumulation, causing issues such as strap jamming. Utility Model Content

[0005] To address the aforementioned issues, an automatic recycling and cutting device for box packing straps with good performance is provided.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An automatic recycling and cutting device for box packing straps includes a recycling feeding mechanism, a recycling shearing mechanism, an end-discharge mechanism, a power mechanism, and auxiliary devices. The recycling feeding mechanism is responsible for continuously feeding the packing straps to the recycling shearing mechanism, the recycling shearing mechanism is responsible for cutting the packing straps into segments, the end-discharge mechanism is responsible for discharging the last segment of packing straps, the power mechanism is responsible for providing power to the recycling feeding mechanism and the end-discharge mechanism, and the position sensor of the auxiliary devices is used to detect whether the packing straps have entered the recycling feeding mechanism and whether the packing straps have been cut.

[0008] Optionally, the recycling feeding mechanism includes at least a clamping cylinder, an upper roller assembly, and a lower roller; the clamping cylinder is fixedly mounted on the frame, the upper roller assembly of the recycling feeding mechanism is mounted on the lower part of the push rod of the clamping cylinder, the lower roller of the recycling feeding mechanism is fixedly mounted on the frame and driven to rotate by a motor, and the vertical movement of the upper roller assembly is driven by the clamping cylinder.

[0009] Optionally, the upper roller assembly includes at least a connecting bracket, spring a, spring b, an upper roller, an upper roller shaft, a bearing, left and right limiting blocks, limiting plates, a rear roller support, and a front roller support. The connecting bracket is fixedly connected to the clamping cylinder, and the connecting bracket is connected to the front roller support and the rear roller support via fixing bolts. The upper roller shaft is connected to the upper roller via bearings. The upper roller shaft can move up and down through a small hole in the middle of the front roller support and the rear roller support under the drive of the upper roller. The main body of spring a is located inside the front roller support, and the main body of spring b is located inside the rear roller support. This structure prevents the springs from slipping and swinging. One end of each spring is connected to the connecting bracket, and the other end is connected to the roller shaft. The upper roller floats up and down according to the thickness of the packing strap under the action of the springs. The front roller support is bolted to the left and right limiting blocks and the limiting plates. A gap smaller than the thickness of the packing strap is left between the left and right limiting blocks and the outer circle of the upper roller.

[0010] Optionally, the length of the spring varies with the thickness of the strapping to ensure that the strapping and the heat-fused double-layer joint can pass smoothly through the recycling feeding mechanism, avoiding strap jamming. The upper roller has a grooved surface to ensure friction, preventing the strapping from slipping through the recycling feeding mechanism. A gap is left between the left and right limit blocks and the upper roller to prevent the strapping from getting caught in the roller during recycling feeding, thus preventing the roller from jamming and recycling failure due to equipment downtime. The limit plate is closed with the frame during mechanism operation to prevent the strapping from swinging and deviating. Under the restriction of the limit plates and limit blocks, the strapping will smoothly enter the recycling cutting mechanism.

[0011] Optionally, the recycling shearing mechanism includes at least a cutting cylinder, a cutting blade assembly, and a guide seat. The cutting blade assembly includes at least a buckle, a blade holder, an upper blade, and a lower blade. The upper blade is fixed to the blade holder by bolts, and the blade holder is fixedly connected to the cutting cylinder by the buckle. The guide seat is fixedly installed on the frame, and the blade holder moves up and down in the guide seat groove by the cutting cylinder. The upper guide groove of the guide seat and the blade holder are in clearance fit. The lower blade is fixedly installed on one side inside the guide seat, and the upper blade and the blade holder have the same outline dimensions.

[0012] The guide seat ensures that the running path of the upper blade does not deviate. The upper blade passes through the guide groove of the guide seat and interacts with the lower blade to cut the packing strap. The packing strap enters the recycling shearing mechanism from the recycling feeding mechanism and is cut into fixed strips by the action of the upper and lower blades, which facilitates subsequent recycling.

[0013] The end discharge mechanism includes a pressure pulley cylinder, an upper pressure pulley, and a lower pressure pulley; the pressure pulley cylinder is connected to the upper pressure pulley of the end discharge mechanism via a bracket, and the lower pressure pulley is fixedly installed on the frame.

[0014] Optionally, the upper pressing pulley is disengaged from the lower roller when the position sensor detects the packing strap; when the sensor detects that the packing strap is empty, the cutting cylinder will no longer control the cutting blade movement and will be in a retracted state, and the upper pressing pulley will be pressed down under the action of the pressing pulley cylinder, and the last section of packing strap will be delivered by the upper pressing pulley and the lower pressing pulley.

[0015] Optionally, the auxiliary device includes at least a position sensor and a timing belt; the position sensor is installed on the side of the frame near the recycling feeding mechanism, and the position sensor has a notch in the middle for detecting the position information of the packing strap; the timing belt is used to connect the lower roller of the power mechanism and the recycling feeding mechanism and the lower pressure pulley of the end discharge mechanism.

[0016] Optionally, the power mechanism includes at least a motor, which is fixedly mounted on the frame. The motor drives the lower roller of the recycling feeding mechanism and the lower pressing pulley of the end discharge mechanism to rotate through auxiliary devices. During recycling feeding, the lower roller drives the upper roller of the recycling feeding mechanism to rotate through friction. The lower pressing pulley drives the upper pressing pulley of the end discharge mechanism to rotate through friction, thereby delivering the last section of strapping.

[0017] Optionally, the position sensor detects the position information of the strapping, the pressing cylinder of the recycling feeding mechanism drives the upper roller assembly of the recycling feeding mechanism to press the strapping downward, the cutting cylinder of the recycling shearing mechanism drives the cutting blade assembly to reciprocate, and the motor of the power mechanism starts to rotate; when the position sensor detects that the strapping is empty, the cutting cylinder will no longer control the cutting blade movement and will be in a retracted state, the pressing pulley cylinder of the end discharge mechanism drives the upper pressing pulley of the end discharge mechanism to move downward, and the last section of strapping will be fed out by the upper pressing pulley and the lower pressing pulley.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. This utility model uses the connection between a spring and an upper roller. The length of the spring changes with the thickness of the packing strap, enabling adaptive recycling and cutting of packing straps with uneven thickness. It can also perform recycling and cutting tasks on double-layer packing straps at the joints.

[0020] 2.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0035] An automatic recycling and cutting device for box packing straps includes a recycling and feeding mechanism. The recycling and feeding mechanism includes at least a pressing cylinder 1, an upper roller assembly 2, and a lower roller 3. The pressing cylinder 1 of the recycling and feeding mechanism is fixedly mounted on a frame 11. The upper roller assembly 2 of the recycling and feeding mechanism is mounted on the lower part of the push rod of the pressing cylinder 1. The lower roller 3 of the recycling and feeding mechanism is fixedly mounted on the frame 11 and driven to rotate by a motor 8. The vertical movement of the upper roller assembly 2 is driven by the pressing cylinder 1. A position sensor 7 is installed at the feed inlet of the recycling and feeding mechanism.

[0036] When in use, when the position sensor 7 detects the strapping, the pressing cylinder 1 drives the upper roller assembly 2 to move downwards. The upper roller assembly 2 presses the strapping downwards. Under the action of the spring, the upper roller 23 will move up and down according to the thickness of the strapping to ensure sufficient pressure on the strapping. At this time, the lower roller 3 starts to rotate under the drive of the motor. The strapping is transported out of the recycling feeding mechanism by the rolling of the upper and lower rollers.

[0037] The upper roller assembly 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 26, limiting plates 27, rear roller support 28, and front roller support 29; the connecting bracket is fixedly connected to the clamping cylinder, the connecting bracket is fixedly connected to the front roller support and the rear roller support, and the upper roller shaft is connected to the upper roller via bearings; Figure 3 As shown, the upper roller shaft can move up and down in the middle hole of the front roller bracket and the rear roller bracket under the drive of the upper roller; the main body of spring a is located inside the front roller bracket, and the main body of spring b is located inside the rear roller bracket. This structure can prevent the springs from slipping and swinging. One end of each of the two springs is connected to the connecting bracket, and the other end of each is connected to the roller shaft; the upper roller floats up and down according to the thickness of the packing strap under the action of the spring; the front roller bracket is connected to the left and right limiting blocks and limiting plates by bolts.

[0038] 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, avoiding strap jamming. The upper roller has a grooved surface to ensure friction, preventing the strapping from slipping through the recycling feeding mechanism. The gap between the left and right limit blocks and the upper roller prevents the strapping from getting caught in the roller during recycling feeding, thus preventing the roller from jamming and recycling failure due to equipment downtime. The limit plate is closed with the frame during mechanism operation to prevent the strapping from swinging and deviating. Under the restriction of the limit plates and limit blocks, the strapping will smoothly enter the recycling cutting mechanism.

[0039] The recycling shearing mechanism includes at least a cutting cylinder 4, a cutting blade assembly 5, and a guide seat 9. The cutting blade assembly 5 includes at least a buckle 51, a blade holder 52, an upper blade 53, and a lower blade 54. The upper blade 53 is fixed to the blade holder 52 by bolts. The blade holder 52 is fixedly connected to the cutting cylinder 4 by the buckle 51. The guide seat 9 is fixedly installed on the frame 11. The blade holder 52 moves up and down in the guide groove of the guide seat 9 by the cutting cylinder 4. The guide groove on the upper part of the guide seat 9 and the blade holder 52 are in clearance fit. The lower blade 54 is fixedly installed on one side inside the guide seat 9. The upper blade 53 and the blade holder 52 have the same outline dimensions.

[0040] In operation, when the position sensor 7 detects the packing strap, the cutting cylinder 4 drives the upper blade 53 to reciprocate up and down. The upper blade 53 passes through the guide groove of the guide seat 9 and interacts with the lower blade 54 to cut the packing strap into fixed sections, facilitating subsequent recycling. The guide seat 9 ensures that the running path of the upper blade 53 does not deviate, guaranteeing the accuracy of the cutting. The upper blade passes through the guide groove of the guide seat and interacts with the lower blade to cut the packing strap; the packing strap enters the recycling feeding mechanism and is cut into fixed strips by the action of the upper and lower blades, facilitating subsequent recycling.

[0041] The end discharge mechanism includes at least a pressure pulley cylinder 61, an upper pressure pulley 63, and a lower pressure pulley 10. The pressure pulley cylinder 61 of the end discharge mechanism is connected to the upper pressure pulley 63 of the end discharge mechanism through a bracket 62, and the lower pressure pulley 10 is fixedly installed on the frame 11.

[0042] In use, when the position sensor 7 detects that the strapping tape is empty, the cutting cylinder 4 will no longer control the upper cutter 53 to move and will be in a retracted state. The pressure roller cylinder 61 of the end discharge mechanism drives the upper pressure roller 62 of the end discharge mechanism to move downward, and the last section of strapping tape will be fed out by the upper pressure roller 62 and the lower pressure roller 63. Since the upper and lower rollers of the recycling feeding mechanism cannot feed out the last section of strapping tape, the strapping tape will accumulate over time. The end discharge mechanism can feed out the last section of strapping tape, avoiding this phenomenon.

[0043] The advantages of this utility model in combining the recycling feeding mechanism and the end discharge mechanism are as follows: When in use, one side of the packing strap is clamped by the upper roller assembly 2 and the lower roller 3, and the other side is clamped by the upper pressure pulley 63 and the lower pressure pulley 10, which can ensure (1) the cutting effect, especially avoiding the problem that existing equipment cannot cut when the packing strap to be recycled is bent too much; (2) combined with the action of spring a221 and spring b222, ensure that the packing strap receives sufficient tension in the early stage, significantly reducing the problem that the equipment is easily jammed during the recycling process due to the packing strap being double or multiple layers at the joint, and the problem that the packing strap is easily rolled into the pressure pulley inside the equipment after cutting because the packing strap to be recycled is partially bent and not straightened in the early stage.

[0044] This utility model also includes a power mechanism and auxiliary devices; the recycling feeding mechanism is responsible for continuously feeding the packing strap to the recycling shearing mechanism, the recycling shearing mechanism is responsible for segmenting and shearing the packing strap, the end discharge mechanism is responsible for sending out the last section of packing strap, the power mechanism is responsible for providing power to the recycling feeding mechanism and the end discharge mechanism, and the position sensor of the auxiliary device is used to detect whether the packing strap has entered the recycling feeding mechanism and whether the packing strap has been sheared.

[0045] The auxiliary device includes at least a position sensor 7 and a timing belt 12; the position sensor is installed on the side of the frame near the recycling feeding mechanism, and the position sensor has a notch in the middle for detecting the position information of the packing strap; the timing belt is used to connect the lower roller of the power mechanism and the recycling feeding mechanism and the lower pressure pulley of the end discharge mechanism.

[0046] The power mechanism includes at least a motor 8, which is fixedly mounted on the frame. The motor drives the lower roller of the recycling feeding mechanism and the lower pressing pulley of the end discharge mechanism to rotate synchronously through the synchronous belt of the auxiliary device. During recycling feeding, the lower roller drives the upper roller of the recycling feeding mechanism to rotate through friction. The lower pressing pulley drives the upper pressing pulley of the end discharge mechanism to rotate through friction, thereby delivering the last section of packing strap.

[0047] The position sensor detects the position information of the packing strap. The pressing cylinder of the recycling feeding mechanism drives the upper roller assembly of the recycling feeding mechanism to press the packing strap downward. The cutting cylinder of the recycling shearing mechanism drives the cutting blade assembly to reciprocate. The motor of the power mechanism starts to rotate. When the position sensor detects that the packing strap is empty, the cutting cylinder will no longer control the cutting blade movement and will be in a retracted state. The pressing pulley cylinder of the end discharge mechanism drives the upper pressing pulley of the end discharge mechanism to move downward. The last section of packing strap will be fed out by the upper pressing pulley and the lower pressing pulley.
