Description

Technical Field

[0001] This invention relates to the field of packaging buckle production technology, specifically to a batch packaging buckle production system and its production method. Background Technology

[0002] Packing buckles are products made to secure the joints of packing straps and tighten them when using them.

[0003] Currently, the production method for packing buckles is single-chip microcomputer. This involves slitting an existing 1250 mm steel plate into 48 26 mm steel strips, then rewinding them into 48 coils, which are then sent to the manufacturer's single-chip microcomputer for single-piece forming. Since only one packing buckle is produced per stroke, this not only results in low production efficiency but also increases slitting and transportation costs. Summary of the Invention

[0004] In view of the above problems, the purpose of this invention is to provide a batch packaging buckle production system and its production method, which is used to directly perform the processes of slitting, flattening, feeding, forming and unloading of 1250 mm steel plates on one machine. Since each stroke produces 48 packaging buckles, the production efficiency is increased by dozens of times.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A batch packaging buckle production system includes: a pitting device, a slitting device, an automatic flattening device, a feeding device, a block fixing device, a bending and forming device, and a material lifting and discharging mechanism; The dimpling device is used to roll and dimpl the steel plate surface in a specified position and sequence. The slitting device is used to longitudinally cut the raw steel plate fed by the piercing device into multiple steel strips. The automatic slitting device is used to lay out multiple steel strips cut by the slitting device neatly and adjust the position of the multiple steel strips. The feeding device is used to transport the steel strip to the bending and forming device at a fixed length and position. The segmented fixing device is used to fix the steel strip to be pressed onto the bending and forming device; The bending and forming device is used to simultaneously cut and bend multiple steel strips into segments. The material lifting and discharging mechanism is used to lift and discharge the formed packaging buckle from the bending and forming device.

[0006] As a preference of the present invention, a dimpling device is installed before the slitting machine. The dimpling device is used to dimple the surface of the raw material steel plate coil. By means of the dimples, the friction between the packing buckle and the packing belt is increased. The dimpling device comprises: two sets of rolling mechanisms. Each set of rolling mechanisms consists of a smooth shaft roller and a dimple wheel arranged vertically. The raw material steel plate passes between the smooth shaft roller and the dimple wheel and is rolled to form dimples. The dimple wheels and the smooth shaft rollers between adjacent two sets of rolling mechanisms are arranged crosswise, that is, the dimple wheels in the front row are arranged above the smooth shaft roller, and the dimple wheels in the rear row are arranged below another smooth shaft roller, so as to roll-print dimples arranged alternately left and right on the upper and lower surfaces of the steel plate.

[0007] As a preference of the present invention, the slitting device comprises: upper and lower slitting machine shafts, and annular knives sleeved on the upper and lower slitting machine shafts. The annular knives uniformly arranged on the upper slitting machine shaft and the annular knives uniformly arranged on the lower slitting machine shaft are arranged crosswise. The two sides of the annular knife serve as cutting edges. The cutting edges of the annular knives on the upper slitting machine shaft and the cutting edges of the adjacent annular knives on the lower slitting machine shaft cut the raw material steel plate coil into steel strips.

[0008] As a preference of the present invention, a turning station is added between the slitting device and the automatic flattening device. The turning station is used to turn over the odd-numbered steel strips so that their burr surfaces face the same direction as those of the even-numbered steel strips, or turn over the even-numbered steel strips so that their burr surfaces face the same direction as those of the odd-numbered steel strips. A turning device needs to be placed at the turning station. The turning device turns over and adjusts the odd-numbered or even-numbered steel strips cut by the slitting device so that the orientations of the steel strips entering the automatic flattening device are unified.

[0009] As a preference of the present invention, the automatic flattening device comprises: a front flattening mechanism and a rear flattening mechanism. The front flattening mechanism is used to pre-flatten and shape multiple steel strips divided by the slitting device. The rear flattening mechanism is used to precisely flatten and shape the steel strips pre-flattened and shaped by the front flattening mechanism; The front flattening mechanism comprises a shaping plate. The shaping plate is provided with two upper and lower rows of uniformly arranged shaping holes, and the two rows of shaping holes are arranged crosswise. The two rows of shaping holes are used to flatten multiple steel strips passing through them; The rear flattening mechanism comprises: upper and lower clamping plates, and positioning plug plates. The upper and lower clamping plates are used to pass through the steel strips pre-flattened and shaped by the front flattening mechanism. The clamping plates are uniformly provided with a plurality of avoiding holes. The positioning plug plates are vertically inserted into the avoiding holes to space the middle interlayer between the upper and lower clamping plates, so as to accurately determine the distance between two steel strips. The two positioning plug plates are positioned by the steel strips.

[0010] Preferably, the block fixing device includes a pressing plate, a thimble, and a compression spring. A plurality of thimble through-holes are provided on the upper die of the bending and forming device. The number of thimble through-holes corresponds to the positions of the steel blocks, and the number is more than twice that of the steel blocks, so that each steel block is pressed by at least two thimbles. The thimble passes through the thimble through-hole and contacts the steel block. There is a compression spring above each thimble. The compression spring squeezes the thimble to position the steel block on the middle die of the bending and forming device, so that the steel block on the middle die does not displace during the shearing and pressing processes. The compression spring is used to assist the thimble to hold the steel block on the middle die.

[0011] Preferably, the bending and forming device includes a lower die, an upper die, a middle die, and a cross die. An upper shearing blade is provided on the upper die, and a lower shearing blade corresponding to the upper shearing blade is provided on the lower die. The upper shearing blade and the lower shearing blade are used to cut the steel strip into steel blocks. The middle die is used to place the steel blocks. A bending groove is provided at the position of the upper die corresponding to the middle die. After the upper die and the lower die are closed, the steel strip is cut into steel blocks. At the same time, the bending groove and the middle die press the steel block into a downward U shape, and the cross die and the middle die squeeze one side of the steel block inward to form the packing buckle.

[0012] Preferably, the material lifting and discharging mechanism includes a material lifting plate, a discharging plate, and an avoidance groove opened on the middle die of the bending and forming device. The position and number of the avoidance grooves correspond to the packing buckles. A plurality of material lifting protrusions are evenly arranged on the material lifting plate. The number and position of the material lifting protrusions correspond to the avoidance grooves. The material lifting protrusions of the material lifting plate are placed in the avoidance grooves and are located below the packing buckles. The material lifting plate lifts the packing buckles on the middle die through the material lifting protrusions, and the discharging plate pushes the lifted packing buckles out of the middle die.

[0013] Another object of the present invention is to provide a production method for a batch packing buckle production system, which specifically includes the following steps: Step S1: Directly insert the raw material steel plate into the pitting device, and use the pitting device to make pits on the surface of the steel plate to increase the friction between the packing buckle and the packing belt through the pits; Step S2: Transport the steel plate after pitting to the slitting device, and use the slitting device to longitudinally cut the steel plate into a plurality of steel strips; Step S3: Use the flipping device to turn over and adjust the single or double steel strips cut by the slitting device so that the burrs of the steel strips entering the automatic flattening device face downward uniformly; Step S4: The steel strips in the same direction enter the front flattening mechanism of the automatic flattening device. Multiple steel strips are flattened and pre-shaped through the shaping holes of the front flattening mechanism. The steel strips pre-flattened by the front flattening mechanism are inserted into the interlayer of the rear flattening mechanism. The upper and lower clamping plates and the positioning insertion plate are used to further adjust the flatness to achieve the effect of precise flattening. Step S5: The feeding device is used to control the sizing and positioning of the steel strips after flattening and shaping, so that the bending and forming device operates according to the sizing and positioning of the feeding device. Step S6: The block fixing device is used to clamp and position the steel strips to be profiled entering the bending and forming device, so as to prevent the steel strips from shifting during the shearing and profiling process. Step S7: The bending and forming device is used to simultaneously cut and segment multiple steel strips and bend and form them. Step S8: The lifting and discharging mechanism is used to push the formed packing buckles out of the bending and forming device.

[0014] The advantages and positive effects of the present invention are as follows: 1. Compared with the traditional production mode, the traditional production mode is a single-piece production mode, that is, a 1250-mm steel plate is cut into 48 steel strips of 26 mm, the steel strips are re-wound onto the steel strip coil, and then transported to the single-chip machine for forming respectively. Since in the prior art, only one packing buckle is produced in each stroke in the single-piece production mode. However, the present invention directly processes the 1250-mm steel plate as a whole, that is, 48 packing buckles are produced in one stroke, thus increasing the production efficiency by dozens of times.

[0015] 2. By installing a pitting device between the raw material steel plate coil rack and the slitting device, the present invention enables the raw material steel plate coil to be pitted before being cut into strips, and thus continuous pitting can be achieved. Compared with the prior art of stamping and pitting single steel strips after slitting, the efficiency is higher.

[0016] 3. The slitting device of the present invention installs cutting knives arranged in a staggered manner on two machine shafts arranged up and down, so that the cutting edges of adjacent cutting knives form a scissors form to shear the steel strips. Compared with the prior art of respectively installing the same number of blades as the number of steel strips to be cut on two machine shafts, not only the number of cutting knives is reduced by half, but also the present invention uses a ring knife (in the form of a sleeve, and both sides of the sleeve are cutting edges) without the need to adjust the gap between the blades.

[0017] 4. In view of the problem that there are burrs on both sides of the steel plate strips after being sheared by the annular knives, and the burr surfaces of the odd-numbered steel plate strips and the adjacent even-numbered steel plate strips are opposite due to the staggered arrangement of the annular knives, the present invention adds a flipping process, thereby making the burr orientations of the steel plate strips entering the automatic flattening device unified, and finally preparing for simultaneously cutting and segmenting and bending and forming multiple steel plate strips by the bending and forming device.

[0018] 5. The automatic flattening device of the present invention consists of two flattening mechanisms, the front and the rear. The front flattening mechanism adopts the method of steel plate build-up welding or can also use the laser hollowing method to meet the initial flattening and pre-flattening, and is characterized by having relatively high mechanical strength. The rear flattening mechanism adopts a splint blade structure, which is characterized by high flattening accuracy and stable operation. This meets the requirements for the subsequent product forming. In addition, the overall flattening structure of this application has the characteristics of simple structure, high precision, and stable effect.

[0019] 6. The feeding device of the present invention can be installed between the two flattening mechanisms, the front and the rear, and is responsible for the task of feeding at a fixed length, fixed time, and fixed position.

[0020] 7. In the present invention, since 48 steel plate strips enter the bending and forming device and are sheared into 48 steel plate blocks, displacement will occur during the pressing process, which affects the finished product rate. Therefore, it is necessary to fix and limit them. The present invention adds a block fixing device, the structure of which is on the upper die of the bending and forming device, mainly composed of a row of ejector pins and compression springs. The number of them must be sufficient to ensure that at least two ejector pins are pressed on each block, so as to achieve the purpose of stably fixing the steel plate blocks.

[0021] 8. In the present invention, since all the steel plate strips have been flattened and their positions adjusted by the automatic flattening device, and the length of the bending and forming device corresponds to the length of all the steel plate strips after flattening, the bending and forming device can form all the steel plate strips at one time.

[0022] 9. The present invention adds a lifting and discharging mechanism to unload the formed packing buckles on the bending and forming device. When the packing buckle is formed, three of its sides are surrounded on the central die of the bending and forming device. The lifting and discharging mechanism of this application adopts a lifting groove (avoidance groove) opened on the central die. After the packing buckle is formed, it is lifted upward by the lifting plate (one side of the finished product is completely lifted above the central die by the lifting plate), and at the same time, the discharging plate is pushed forward to discharge the material. Thus, a cycle is completed. And so on. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0031] In the following description, for the purpose of illustration, in order to provide a comprehensive understanding of one or more embodiments, many specific details are set forth. However, it is obvious that these embodiments can also be implemented without these specific details. In other instances, well-known structures and devices are shown in block diagram form for the purpose of facilitating the description of one or more embodiments.

[0032] Refer to Figure 1-7, this embodiment provides a batch production system for packing buckles, including: a raw material uncoiler 1, a dimpling device 2, a slitting device 3, a flipping station 4, an automatic flattening device 5, a feeding device 6, a block fixing device 7, a bending and forming device 8, and a lifting and discharging mechanism 9; the raw material uncoiler 1 is used for leveling a steel plate coil of 1250 mm (this is a common size and can also be 1000 mm or a smaller size), and then sending it to subsequent equipment for processing and forming. Among them, the slitting device 3 needs to complete 48 slittings; before the slitting device 3, the steel plate to be divided needs to be dimpled. The 48 dimpling wheels of the dimpling device 2 are used to dimple the成片钢板 (should be "sheet steel plate" here) to increase the friction between the packing buckle and the packing belt. A flipping station 4 needs to be added between the slitting device 3 and the automatic flattening device 5. After flipping, all the steel plate strips enter the automatic flattening device 5 with the burr directions unified. The automatic flattening device 5 flattens the multiple steel plate strips cut by the slitting device neatly; the flattened steel plate strips are fixed and positioned by the block fixing device 7 for the steel plate strips to be profiled after entering the bending and forming device 8 to prevent them from shifting during the profiling process; the bending and forming device simultaneously cuts and segments and bends and forms 48 steel plate strips. The lifting and discharging mechanism 9 pushes the formed packing buckles out of the bending and forming device 8, and the feeding device 6 is installed between the front flattening mechanism and the rear flattening mechanism of the automatic flattening device 5 for feeding according to fixed length and positioning.

[0033] Refer to Figure 1 and Figure 2 , in this embodiment, a dimpling device 2 is installed between the raw material steel plate coil uncoiler 1 and the slitting device 3. The dimpling device 2 is used to dimple (concave and convex points) the surface of the raw material steel plate coil to increase the friction between the packing buckle and the packing belt. Since the dimpling device is installed between the raw material steel plate coil uncoiler and the slitting device in this invention, the raw material steel plate coil can be dimpled before being cut into strips, and thus rolling dimpling can be achieved, which is more efficient compared with the previous single steel plate strip stamping dimpling. The dimpling device 2 includes: two groups of rolling mechanisms. Each group of rolling mechanisms consists of a smooth shaft roller 201 and a dimpling roller 202 arranged up and down. The smooth shaft roller 201 and the dimpling roller 202 are used to pass the raw material steel plate and roll and dimple the raw material steel plate. The two dimpling rollers 202 and the two smooth shaft rollers 201 between adjacent two groups of rolling mechanisms are arranged crosswise, that is, the dimpling rollers 202 in the front row are arranged above the smooth shaft rollers 201, and the dimpling rollers 202 in the rear row are arranged below the smooth shaft rollers 201. Among them, the dimpling wheels 204 on adjacent two dimpling rollers 202 are arranged staggeredly, that is, the dimpling wheels 204 on the previous dimpling roller 202 correspond to the interval gaps 203 on the next dimpling roller 202. In addition, adjusting jackscrews are provided on the dimpling wheels 204 to adjust the radial clearance between the dimpling wheels 204 and the roller shafts to improve the dimpling effect.

[0034] Refer to Figure 1 and Figure 3 Figure 3 , the strip dividing device 3 in this embodiment includes: an upper strip dividing machine shaft 301, a lower strip dividing machine shaft 302, and an annular cutter 303 sleeved on the upper strip dividing machine shaft 301 and the lower strip dividing machine shaft 302. The annular cutters 303 uniformly arranged on the upper strip dividing machine shaft 301 and the annular cutters 303 uniformly arranged on the lower strip dividing machine shaft 302 are arranged staggeredly, that is, the annular cutter 303 on the upper strip dividing machine shaft 301 corresponds to the gap between the annular cutters 303 on the lower strip dividing machine shaft 302. Both sides of the annular cutter 303 are used as cutting edges. The cutting edges of the annular cutters 303 on the upper strip dividing machine shaft 301 and the cutting edges of the adjacent annular cutters 303 on the lower strip dividing machine shaft 302 cut the raw material steel plate into multiple steel strips.

[0035] Refer to Figure 1 <00001^, a turning station 4 is added between the strip dividing device 3 and the automatic laying device 5 in this embodiment. The turning station 4 is used to turn over the odd-numbered steel strips so that their burr surfaces face the same direction as those of the even-numbered steel strips. The reason is that there are burrs on both sides of the steel strips after being cut by the annular cutter, and the staggeredly arranged annular cutters make the burr surfaces of the odd-numbered steel strips opposite to those of the adjacent even-numbered steel strips. By turning over the odd-numbered or even-numbered steel strips cut by the strip dividing device 3 through the turning station 4, the orientation of the steel strips entering the automatic laying device is unified. When 48 steel strips come out of the strip dividing device 3, half of the steel strips with pitted surfaces and burr surfaces facing up can be turned over through turning, ensuring that the pitted surfaces and burr directions of all the steel strips are kept consistent and facing down.

[0036] Refer to Figure 1 and Figure 4 Figure 4 , the automatic laying device 5 in this embodiment includes: a front laying mechanism 501 and a rear laying mechanism �02. The front laying mechanism 501 is used for pre-laying and shaping the multiple steel strips divided by the strip dividing device 3, and the rear laying mechanism 502 is used for precisely laying and shaping the steel strips pre-laid and shaped by the front laying mechanism 501; The front laying mechanism 501 includes a shaping plate 503. The shaping plate 503 is provided with two rows of uniformly arranged shaping holes 504 up and down, and the two rows of shaping holes 504 are arranged staggeredly, that is, the gap between two shaping holes 504 in the upper row corresponds to the shaping holes 504 in the lower row. The two rows of shaping holes 504 are used for laying the multiple steel strips passing through. Among them, the shaping plate 503 adopts the method of stacking and welding thin steel plates, or the laser hollowing method, because the mechanical strength of the front laying mechanism 501 is relatively high. In this way, the requirements for relatively high mechanical strength of the initial laying structure can be met; The post-flattening mechanism 502 includes: two upper and lower clamping plates 505, and a positioning insertion plate (in this invention, a wallpaper blade is used) 506. Between the two upper and lower clamping plates 505, the steel strips pre-flattened and shaped by the pre-flattening mechanism 501 are to pass through. A plurality of avoidance holes are evenly distributed on both the upper and lower clamping plates 505. The positioning insertion plate 506 is vertically inserted into the avoidance holes to space the middle sandwich layer of the two upper and lower clamping plates 505. The distance between the two positioning insertion plates 506 is for the steel strips to pass through, so as to achieve an accurate flattening effect.

[0037] Refer to Figure 1 and Figure 6 Refer to

[0038] and Figure 5 In this embodiment, the block fixing device 7 includes: a pressing plate 703, a thimble 701, and a compression spring 702. A plurality of thimble through holes are opened on the upper die 802 of the bending and forming device 8. The number of thimble through holes corresponds to the position of the steel blocks, and the number is more than twice that of the steel blocks. The thimble 701 passes through the thimble through hole and contacts the steel block. The pressing plate presses the thimble 701 to position the steel block on the middle die 803 of the bending and forming device 8, so as to prevent the steel block on the middle die 803 from shifting during the shearing process of the upper shearing blade 805 and the lower shearing blade 806. The compression spring 702 is sleeved on the thimble 701, and the compression spring 702 is used to assist the thimble 701 to hold the steel block on the middle die 803.

[0039] Refer to Figure 7 In this embodiment, the material lifting and discharging mechanism 9 includes: a material lifting plate 902, a discharging plate 901, and an avoidance groove 903 opened on the middle die 803 of the bending and forming device 8. The position and number of the avoidance groove 903 correspond to the packing buckles. A plurality of material lifting protrusions 904 are evenly arranged on the material lifting plate 902. The number and position of the material lifting protrusions correspond to the avoidance groove 903. The material lifting protrusions of the material lifting plate 902 are placed in the avoidance groove 903 and below the packing buckles. The material lifting plate 902 lifts the packing buckles on the middle die 803 through the material lifting protrusions, and the discharging plate 901 pushes the lifted packing buckles out of the middle die 803. Among them, refer to Figure 7 , the material lifting plate 902 is located on one side above the intermediate die 803. When the material lifting plate 902 is behind the intermediate die 803, the material lifting plate 902 pushes one side of the straight edge of the packing buckle, thus completing the discharging.

[0040] Embodiment 2 This embodiment provides a production method for a batch packing buckle production system, which specifically includes the following steps: Step S1: The steel plate on the raw material steel plate coiling and leveling machine 1 directly enters the dimpling device 2, and the dimpling device 2 is used to dimple the surface of the steel plate, and the friction between the packing buckle and the packing belt is increased through the dimples; Step S2: The steel plate after dimpling is conveyed to the slitting device 3, and the slitting device 3 is used to longitudinally cut the steel plate into 48 steel strips; Step S3: Use the flipping device to turn over half (24) of the 48 steel strips with burrs facing up after being cut by the slitting device 3 so that the burr directions of the steel strips entering the automatic flattening device 5 are uniformly facing down; Step S4: The 48 steel strips with the same direction enter the 48 sizing holes 504 of the front flattening mechanism 501 of the automatic flattening device 5, and the 48 steel strips are flattened and pre-shaped through the 48 sizing holes 504 of the front flattening mechanism 501. Since the front flattening mechanism 501 adopts the method of thin steel plate stack welding or laser hollowing, its flattening mechanical strength is relatively high, so as to meet the initial flattening effect and the requirements of relatively large mechanical strength. Then insert the steel strips pre-flattened by the front flattening mechanism 501 into the sandwich layer of the rear flattening mechanism 502, adjust with the upper and lower clamping plates 505, and then adjust with the positioning plug board 506 to achieve a precise flattening effect, which is characterized by high flattening accuracy and stable operation. Thus, it meets the requirements for the subsequent product forming.

[0041] Step S5: Use the feeding device 6 to perform sizing and positioning on the 48 steel strips after flattening and shaping, and send them into the bending and forming device 8 to complete the bending and forming; Step S6: Use the block fixing device 7 to clamp and fix the steel strips to be profiled entering the bending and forming device 8, so as to prevent the steel strips from shifting during the profiling process; Step S7: Use the bending and forming device 8 to simultaneously cut and segment and bend and form the 48 steel strips; Step S8: Use the material lifting and discharging mechanism 9 to lift and discharge the formed packing buckle from the bending and forming device 8.

[0042] Above is only the specific implementation manner of the present invention. However, the protection scope of the present invention is not limited thereto. Any person skilled in the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, and all of them should be covered within the protection scope of the present invention.

6. A batch packaging buckle production system according to claim 1, characterized in that, The segmented fixing device includes a pressure plate, ejector pins, and compression springs. The upper die of the bending forming device is provided with multiple ejector pin through holes. The number of ejector pin through holes corresponds to the position of the steel plate and is more than twice that of the steel plate, so that each steel plate is pressed by at least two ejector pins. The ejector pins pass through the ejector pin through holes and contact the steel plate. Each ejector pin has a compression spring above it. The compression springs squeeze the ejector pins to position the steel plate on the intermediate die of the bending forming device, so that the steel plate on the intermediate die does not shift during shearing and forming. The compression springs are used to assist the ejector pins in holding the steel plate on the intermediate die.

7. A batch packaging buckle production system according to claim 1, characterized in that, The bending and forming device includes a lower die, an upper die, an intermediate die, and a horizontal die. The upper die is provided with an upper shearing blade, and the lower die is provided with a lower shearing blade corresponding to the upper shearing blade. The upper and lower shearing blades are used to cut steel strips into steel plates. The intermediate die is used to hold the steel plates. The upper die is provided with a bending groove corresponding to the position of the intermediate die. After the upper and lower dies are closed, the steel strips are cut into steel plates. At the same time, the bending groove and the intermediate die press the steel plates into a downward U-shape. The horizontal die and the intermediate die squeeze one side of the steel plate inward to form the buckle.

8. A batch packaging buckle production system according to claim 1, characterized in that, The material lifting and discharging mechanism includes: a lifting plate, a discharging plate, and a clearance groove formed on the intermediate mold of the bending and forming device. The position and number of the clearance groove correspond to the packing buckle. The lifting plate is evenly provided with multiple lifting protrusions. The number and position of the lifting protrusions correspond to the clearance groove. The lifting protrusions of the lifting plate are placed in the clearance groove and located below the packing buckle. The lifting plate lifts the packing buckle on the intermediate mold through the lifting protrusions, and the discharging plate pushes the lifted packing buckle out of the intermediate mold.

9. The production method of a batch packaging buckle production system according to claim 5, characterized in that, Includes the following steps: Step S1: Insert the raw material steel plate directly into the prickling device and use the prickling device to prick the surface of the steel plate to increase the friction between the packing buckle and the packing strap. Step S2: The steel plate after being pitted is conveyed to the slitting device, which cuts the steel plate longitudinally into multiple steel strips. Step S3: Use the flipping device to flip over the odd or even number of steel strips cut by the slitting device so that the burrs of the steel strips entering the automatic laying device are all facing down. Step S4: Steel strips of the same direction enter the front paving mechanism of the automatic paving device. Multiple steel strips are laid flat and pre-shaped through the shaping holes of the front paving mechanism. The steel strips pre-paved by the front paving mechanism are inserted into the interlayer of the rear paving mechanism. The flatness is further adjusted by the upper and lower clamping plates and the positioning plate to achieve the effect of precise paving. Step S5: Use the feeding device to control the length and position of the flattened and shaped steel strips, so that the bending and forming device can operate according to the length and position of the feeding device. Step S6: Use the segmented fixing device to clamp and position the steel strip to be pressed in the bending and forming device to prevent the steel strip from shifting during the shearing and pressing process; Step S7: Use a bending and forming device to simultaneously cut and bend multiple steel strips into sections; Step S8: Use the material lifting and unloading mechanism to push the formed packaging buckle out of the bending and forming device.
