Description

Technical Field

[0001] This invention relates to the field of packaging technology, and in particular to an automatic buckle-fastening machine and method for steel strap boxes. Background Technology

[0002] Steel-strapped boxes, also known as nail-free boxes, are foldable outer packaging products. They are boxes that can be assembled and sealed. Steel-strapped boxes are made of high-strength galvanized steel straps, which will not loosen from installation to transportation. This can protect customers' goods from damage and is widely used in transportation.

[0003] Traditional steel-strapped boxes are made of sheet metal. First, the steel strips are pressed onto the bottom plate of the wooden box pallet using a press. Then, the square posts and foot strips are assembled onto the bottom plate with nails to form the pallet. Next, the steel strips and buckles are pressed onto the surrounding panels and cover plates using a press. Generally, they are assembled on-site to form a wooden box. A buckle-attaching machine is needed when installing the buckles on the sheet metal.

[0004] Existing snap fastener machines can only install snap fasteners on one side of the wooden board. When installing on other sides, the position of the wooden board needs to be adjusted manually, which reduces work efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic buckle-fastening machine and method for steel strap boxes, which can automatically buckle multiple edges of wooden boards, making buckling easier and improving work efficiency.

[0034] First Embodiment

[0035] Please see Figures 1-3This invention provides an automatic buckle-fastening machine 118 for steel strap boxes, including a support assembly 101, a conveying assembly 102, a buckle-fastening assembly 103, and a discharge assembly 104. The support assembly 101 includes a base 105 and a support frame 106. The support frame 106 is fixedly connected to the base 105 and located on one side of the base 105. The conveying assembly 102 includes a conveyor line 107, a rotating table 108, a support table 109, a pressure plate 110, a rotating motor 111, and a first cylinder 112. The conveyor line 107 is located on one side of the base 105, the support table 109 is located on one side of the conveyor line 107, the rotating table 108 is rotatably connected to the support table 109 and located on one side of the support table 109, and the first cylinder 112 is located above the rotating table 108. The machine 111 is fixed on the output end of the first cylinder 112. The pressure plate 110 is fixedly connected to the output end of the rotating motor 111. The buckling assembly 103 includes a drive cylinder 113, a support block 114, a limit block 115, a screw motor 116, a mounting block 117, and a buckling machine 118. The drive cylinder 113 is fixed on the support frame 106. The support block 114 is fixedly connected to the output end of the drive cylinder 113. The limit block 115 is fixed on the support block 114. The mounting block 117 is slidably connected to the support block 114 and is located on one side of the support block 114. The screw of the screw motor 116 is threadedly connected to the mounting block. The buckling machine 118 is fixed on the mounting block 117. The discharge assembly 104 is disposed on one side of the rotating table 108.

[0036] In this embodiment, the base 105 provides stable support for the support frame 106. A conveyor line 107 is provided on one side of the base 105, allowing the wooden board to be processed to be placed on the conveyor line 107 for transport. The board is then transported to the rotating table 108. The first cylinder 112 is activated to move the pressure plate 110 downwards to clamp the board. Then, the drive cylinder 113 is activated to move the support block 114 closer to the board, and the limiting block 115 holds it against the board, thus adjusting the board's position and fixing the relative position of the buttoning machine 118 and the board. The screw motor 116 is then activated to drive the mounting block 117 to slide on the support block 114, thereby driving the buttoning machine 118 to perform buttoning. This allows for easier buttoning on one side of the board. After resetting the support block 114, the rotating motor 111 is activated to rotate the board 90 degrees, and then buttoning is performed again in the same manner. This makes buttoning the board more convenient and improves work efficiency.

[0037] Second Embodiment

[0038] Please see Figures 4-8 Based on the first embodiment, the present invention also provides an automatic buckle fastening machine 118 for steel strap boxes. The support assembly 101 further includes an anti-slip pad 201, which is fixedly connected to the base 105 and located at the bottom of the base 105. The base 105 of the equipment incorporates anti-slip pads 201, which are firmly fixed to the bottom of the base 105, effectively preventing displacement or sliding during operation. Especially under high-frequency operation or uneven ground conditions, it can significantly improve the safety and stability of the equipment.

[0039] The rotating table 108 includes multiple rotating rollers 202, a rotating table body 203, a mounting plate 204, and a first spring 205. The rotating table body 203 is rotatably connected to the support platform 109, and the mounting plate 204 is slidably connected to the rotating table body 203. The first spring 205 is disposed between the mounting plate 204 and the rotating table body 203. The multiple rotating rollers 202 are rotatably mounted on the rotating table body 203. The rotating table 108 is a key component for steel belt conveying, consisting of rotating rollers 202, rotating table body 203, mounting plate 204, and first spring 205. The flexible connection between the rotating table body 203 and the support platform 109 ensures smooth transmission of the steel belt. The sliding connection between the mounting plate 204 and the rotating table body 203, combined with the buffering effect of the first spring 205, allows the pressure plate 110 to press the rotating rollers 202 into the rotating table body 203 when it presses down, thereby keeping the wooden board stable during processing.

[0040] The pressure plate 110 includes a support plate 206, a pressure plate body 207, and a second spring 208. The support plate 206 is fixed to the output end of the rotary motor 111. The pressure plate body 207 is slidably connected to the support plate 206 and located at the bottom of the support plate 206. The second spring 208 is disposed between the support plate 206 and the pressure plate body 207. The pressure plate 110 assembly is connected to the output end of the rotary motor 111 via the support plate 206, and the pressure plate body 207 is slidably engaged with the support plate 206. This design, combined with the elastic effect of the second spring 208, enables uniform and adjustable pressure control on the wooden board, ensuring the tightness and quality of the buckle during application.

[0041] The buckling assembly 103 also includes a return spring 209, which is disposed between the drive cylinder 113 and the support block 114. After the operation is completed, the return spring 209 can drive the support block 114 to reset.

[0042] The buckle assembly 103 also includes a rotating wheel 210, which is rotatably connected to the limiting block 115 and located on one side of the limiting block 115. The rotating wheel 210 can reduce the friction of the limiting block 115 during movement, making the movement more stable.

[0043] The snap-fit ​​assembly 103 further includes a first ranging unit 211, a second ranging unit 212, and a processor 213. The first ranging unit 211 is fixed to the mounting block 117, and the second ranging unit 212 is fixed to the support frame 106. The processor 213 is connected to the first ranging unit 211, the second ranging unit 212, and the screw motor 116. The first ranging unit 211 measures the distance between the mounting block 117 and the support frame 106, and the second ranging unit 212 measures the distance from the support frame 106 to the bottom of the wooden board. This provides a relative distance, which is then adjusted by the processor 213 to ensure a more accurate snap-fit ​​position.

[0044] The processor 213 includes a distance calculation unit 214, a calibration unit 215, and a control unit 216. The distance calculation unit 214 calculates the relative distance based on the distance values ​​from the first ranging unit 211 and the second ranging unit 212. The calibration unit 215 converts the relative distance into a calibration signal for the screw motor 116. The control unit 216 adjusts the screw motor 116 based on the calibration signal. The distance calculation unit 214 primarily processes real-time data from the first ranging unit 211 and the second ranging unit 212. These two ranging units are installed at different locations on the equipment and continuously monitor the actual position of the steel strip during processing using advanced optical, ultrasonic, or other non-contact sensing technologies. After receiving these raw distance measurements, the distance calculation unit 214 quickly calculates the relative distance between the two ranging points using an advanced algorithm. The calibration unit 215, based on this, plays a role in data conversion and optimization. Based on the relative distance calculated by the distance calculation unit 214, it converts the distance into a specific calibration signal for the screw motor 116 using a preset mathematical model or algorithm. This step is crucial because it ensures that the theoretical calculation value can be accurately translated into control commands in the physical world. That is, according to the actual position requirements of the latching action, the rotation angle, speed, or force of the screw motor 116 is precisely adjusted to achieve the purpose of fine-tuning the latching tongue positioning or feeding. As the final execution link of the command, the control unit 216 immediately performs dynamic adjustments to the screw motor 116 after receiving the calibration signal from the calibration unit 215. This adjustment process involves complex logical judgment and feedback mechanisms, aiming to achieve closed-loop control. That is, by monitoring the working status and effect of the screw motor 116 in real time, the control strategy is continuously fine-tuned until the optimal latching position and force are achieved.

[0045] The discharge assembly 104 includes a push plate 217, a push cylinder 218, and a discharge roller 219. The push cylinder 218 is fixed to one side of the support frame 106. The push plate 217 is connected to the output end of the push cylinder 218 and is close to the support platform 109. The discharge roller 219 is located on the side of the support platform 109 away from the push plate 217. The discharge assembly 104 consists of the push plate 217, the push cylinder 218, and the discharge roller 219. Through the action of the push cylinder 218, the push plate 217 pushes the buckled steel strip to the discharge roller 219, realizing continuous operation.

[0046] The discharge assembly 104 also includes a second spring 208, which is disposed between the push plate 217 and the push cylinder 218. During this process, the second spring 208 further optimizes the smoothness of the push plate 217's movement, reduces impact and wear, and can also drive the push plate 217 back to its initial position after the work is completed.

[0047] In summary, this type of automatic buckle-tying machine 118 for steel strap boxes comprehensively utilizes precision mechanical design, automatic control technology, and materials science to ensure automation, high efficiency, and precision throughout the entire process from raw material input to finished product output.

[0048] Third Embodiment

[0049] Please see Figure 9 Based on the second embodiment, the present invention also provides an automatic buckle-fastening method for steel strap boxes, comprising:

[0050] S101 places the wooden board onto the conveyor line 107 and transports it to the rotating table 108;

[0051] Conveyor line 107 then starts, smoothly and precisely delivering the wooden planks to the designated turntable 108. This step ensures seamless integration with subsequent processing steps while reducing the labor intensity of manual handling.

[0052] S102 starts the first cylinder 112, which drives the pressure plate 110 to move down and clamp the template;

[0053] Once the wooden board reaches the rotating table 108, the system immediately activates the first cylinder 112. Through a precisely designed mechanical transmission, the pressure plate 110 slowly descends, clamping the wooden board evenly and firmly. This action effectively prevents the wooden board from slipping or shifting during processing, ensuring the accuracy of the clamping.

[0054] S103 starts the drive cylinder 113 to drive the support block 114 to approach the edge of the wooden board, and the limit block 115 holds and limits the edge of the wooden board.

[0055] The movement of the support block 114 is accurate to the millimeter level, and the edge of the wooden board is precisely supported and limited by the pre-set limit block 115, ensuring the absolute accuracy of the buckle position and avoiding buckle misalignment caused by inaccurate positioning.

[0056] S104 starts the screw, which drives the mounting block 117 to slide on the support block 114, thereby driving the fastening machine 118 to fasten the wooden board;

[0057] The system activates the electric screw mechanism, driving the mounting block 117, on which the fastening machine 118 is installed, to slide smoothly along the guide groove of the support block 114 until it contacts the surface of the wooden board. At this point, the fastening machine 118 quickly and accurately completes the fastening operation at the predetermined position.

[0058] After S105 fastens, the rotating motor 111 is started to drive the template to rotate 90°, and then the fastening machine 118 fastens again;

[0059] After fastening one side is completed, the system automatically starts the rotating motor 111, which drives the wooden board and clamping device to rotate precisely 90 degrees, moving to the next fastening position. Subsequently, the fastening machine 118 starts again to perform the same precise fastening operation on the other side of the wooden board. This continuous action ensures that the four sides of the wooden box are evenly stressed, enhancing its structural stability.

[0060] After the S106 wooden board is snapped shut, it is sent out through the discharge assembly 104.

[0061] After all the pre-defined positions on the wooden board have been secured with buckles, the system automatically switches to the discharge mode. The discharge component 104 smoothly removes the secured wooden board from the turntable 108 and sends it to the next process or directly to the packaging area. The entire process is smooth and efficient, significantly improving the overall throughput of the production line.
