Description

Technical Field

[0001] The utility model relates to the field of Kaiping line, in particular to a discharging device for Kaiping line. Background Art

[0002] Currently, the process of converting metal coils into metal sheets is typically done through a flattening line. Specifically, on a flattening line, the metal coils undergo uncoiling and flattening to produce metal sheets. Finally, the flattening line's shearing machine cuts the metal sheets into metal sheets.

[0003] To quickly deliver sheet metal, most cutting machines currently use a pair of rollers positioned outside the output end of the cutting machine to clamp the sheet metal and rotate rapidly to deliver the sheet metal. To ensure the rollers effectively move the sheet metal, they are typically clamped with a relatively high clamping force. While this method allows for quick and efficient sheet metal delivery, it also has significant drawbacks. Specifically, because most existing sheet metal is relatively thin and weak (especially for packaging), and dust-free production is difficult in the workshops of Kaiping production lines, the high clamping force can easily deform the sheet metal and / or cause dust to be imprinted on it. This can result in noticeable indentations on the sheet metal, which can reduce production quality. This indentation is particularly pronounced when a film coating is present on the sheet metal surface, and such indentations cannot be reversed, leading to defective products and even the scrapping of the sheet metal.

[0004] Furthermore, to ensure smooth transport of cut metal sheets, conveyor belt assemblies are often placed outside the shearing machine's output port. Furthermore, to ensure the conveyor belt assembly can stably receive the metal sheets, the conveying surface of the conveyor belt assembly is often positioned diagonally below the shearing machine's output port and below the rollers. As a result, the metal sheet bends downward under its own weight after passing through the rollers, causing it to strike the conveying surface of the conveyor belt assembly at an angle, with the edges of the sheet striking the surface first. Because the ends of the metal sheet are very sharp after being cut by the shearing machine, and the conveyor belts that form the conveying surface of the conveyor belt assembly are often made of rubber or plastic, the structural strength of the conveyor belt is very limited. Furthermore, to ensure production efficiency, the metal sheets are often conveyed at high speeds. Consequently, when the ends of the metal sheet strike the conveyor belt at an angle, the edges of the metal sheet strike the conveyor belt with great force, which can easily cause large scratches on the conveyor belt, significantly accelerating its aging and increasing maintenance costs for users.

[0005] Therefore, it is very necessary to design a kaiping line discharging device to solve the above-mentioned technical problems. Utility Model Content

[0006] The purpose of the present invention is to solve the above-mentioned problems and shortcomings, and to provide a leveling line discharging device, which can avoid the generation of indentations, which can not only help improve the production quality of metal sheets, but also greatly reduce the probability of defective products and waste products; and it can also help to stably position the metal sheets, which can not only greatly reduce the probability of vibration and displacement during the cutting process, but also reduce the probability of deformation of the metal sheets, and can help to accurately convey the metal sheets; at the same time, it can not only help to stably catch the metal sheets, but also avoid the corners of the ends of the metal sheets from quickly hitting the conveyor belt in a beveled manner, which can help to greatly reduce the probability of large scratches on the conveyor belt, thereby helping to greatly reduce the aging speed of the conveyor belt, and then help to reduce the maintenance cost of the user.

[0007] The technical solution of the present utility model is achieved as follows:

[0008] A discharge device for a folding line is characterized in that it includes a conveyor belt assembly, and a blowing and suction device capable of blowing air upward and sucking air downward is provided on or beside the conveyor belt assembly; the blowing and suction device includes a blowing and suction air generating device and a position detection device for detecting the position of a cutting knife on a cutting machine, and the blowing and suction air generating device is electrically connected to the position detection device.

[0009] Preferably, the blowing and suction device is an integrated blowing and suction device with the same opening for blowing and suction.

[0010] Preferably, the blowing and suction device is a blowing and suction device that blows air when the cutting machine feeds materials and sucks air when the cutting machine cuts and / or retracts the knife.

[0011] Preferably, the blowing and suction generating device includes a reversing valve, a control circuit module, two fans, and at least one blowing and suction pipe that can blow air upward and suck air downward. The reversing valve is provided with a first connecting pipe port, a second connecting pipe port, and a third connecting pipe port. The reversing valve can make the second connecting pipe port and the third connecting pipe port alternately connected to the first connecting pipe port. The first connecting pipe port is connected to the blowing and suction pipes. The suction port of one fan is connected to the second connecting pipe port, and the blowing port of the other fan is connected to the third connecting pipe port. The reversing valve and the position detection device are electrically connected to the control circuit module.

[0012] Preferably, the position detection device is a detection module for detecting the rotation angle position of the hob shaft on the cutting machine.

[0013] Preferably, a wide blowing and suction port and a narrow blowing and suction port are respectively provided at both ends of the top of the blowing and suction air pipe, and the wide blowing and suction port is close to the air source end of the blowing and suction air pipe, and the narrow blowing and suction port is away from the air source end of the blowing and suction air pipe, and the wide blowing and suction port and the narrow blowing and suction port are arranged side by side along the conveying direction of the conveyor belt assembly.

[0014] Preferably, the conveyor belt assembly includes a positioning frame and at least one conveyor belt, the conveyor belt is wound around the positioning frame, and the conveyor belt is provided with at least one group of air holes, the air hole group includes a plurality of blowing and suction air holes that penetrate from the outer wall of the conveyor belt to the inner wall of the conveyor belt, and the blowing and suction air holes are arranged side by side along the circumference of the conveyor belt, the blowing and suction air pipe is arranged on the inner side of the conveyor belt, and the wide blowing and suction port and the narrow blowing and suction port on the blowing and suction air pipe are facing upward, and the wide blowing and suction port and the narrow blowing and suction port are facing the blowing and suction air holes at corresponding positions.

[0017] The present invention has the following beneficial effects: By disposing a blowing and suction device on or beside the conveyor belt assembly that can blow air upward and suck air downward, the blown air from the blowing and suction device can not only blow the material entering the conveyor belt assembly upward, but also suck the material conveyed by the conveyor belt assembly downward. Thus, when the blowing and suction device blows air, the metal sheet entering the conveyor belt assembly is blown upward, preventing the corners of the metal sheet from rapidly impacting the conveyor belt in a beveled manner. This helps significantly reduce the chance of large scratches on the conveyor belt, thereby significantly reducing the aging rate of the conveyor belt and, in turn, lowering maintenance costs for the user. Furthermore, the provision of the blowing and suction device can also meet the need to reduce friction, which ensures that the metal sheet moves very stably and smoothly on the conveyor belt assembly, thereby ensuring excellent performance. Furthermore, the conveyor belt assembly can still meet normal installation and material connection requirements, thereby facilitating stable reception of the metal sheet, and the kaiping line discharging device is highly adaptable. When the blowing and suction device draws air, it draws the metal sheet conveyed by the conveyor belt assembly downward, eliminating the need for counter-rollers to remove the metal sheet and thus avoiding indentations. This not only improves the production quality of the metal sheet, but also significantly reduces the chances of defective and scrapped products. Furthermore, the suction of the blowing and suction device helps to stably position the metal sheet, significantly reducing the chances of vibration and displacement during the shearing process, as well as the chances of deformation of the metal sheet, and facilitates accurate conveyance of the metal sheet.

[0021] Figure 4 It is a partial structural schematic diagram of the conveyor belt assembly in the utility model. DETAILED DESCRIPTION

[0022] like Figure 1 As shown, the utility model describes a kaiping line discharging device, comprising a conveyor belt assembly 1, on or beside which is provided a blowing and sucking device 2 capable of blowing air upward and sucking air downward; and the blowing and sucking device 2 can blow air above the conveying surface of the conveyor belt assembly 1 when blowing air, and can also suck air below the conveying surface of the conveyor belt assembly 1 when sucking air.

[0023] On the discharge device of the kaiping line, a blowing and sucking device 2 that can blow air upward and suck air downward is arranged on or beside the conveyor belt assembly 1. This can not only use the blowing of the blowing and sucking device 2 to blow the material on the conveyor belt assembly 1 upward, but also use the suction of the blowing and sucking device 2 to suck the material conveyed by the conveyor belt assembly 1 downward.

[0024] In this way, when the blowing and suction device 2 blows air, the metal sheet entering the conveyor belt assembly 1 can be blown upward to prevent the corners of the metal sheet from quickly hitting the conveyor belt in a beveled manner. The flattening line discharge device can greatly reduce the probability of large scratches on the conveyor belt, thereby greatly reducing the aging rate of the conveyor belt, and further reducing the user's maintenance costs. The setting of the blowing and suction device 2 can also meet the need to reduce friction, which can make the movement of the metal sheet on the conveyor belt assembly 1 very stable and smooth, so that the flattening line discharge device has very good performance. In addition, the conveyor belt assembly 1 can still meet the normal installation and material connection requirements, thereby facilitating the stable reception of the metal sheet. The applicability of the flattening line discharge device is very strong.

[0025] When the blowing and suction device 2 draws air, it draws the metal sheet conveyed by the conveyor belt assembly 1 downward, eliminating the need for counter-rolling rollers to remove the metal sheet, thereby avoiding indentations. This not only improves the production quality of the metal sheet, but also significantly reduces the probability of defective and waste products. Furthermore, the suction of the blowing and suction device 2 helps to stably position the metal sheet, significantly reducing the probability of vibration and displacement during the shearing process, as well as the probability of deformation of the metal sheet, and facilitates the accurate conveyance of the metal sheet.

[0026] The blowing and suction device 2 can blow air both directly upward and diagonally upward, and can also draw air both directly downward and diagonally downward, effectively meeting the needs of practical use. When blowing, the air expelled by the blowing and suction device 2 acts on the metal sheet entering the conveyor belt assembly 1, thereby preventing the edges of the sheet from directly impacting and reducing friction. When drawing air, the suction force generated by the blowing and suction device 2 pulls the metal sheet conveyed on the conveyor belt assembly 1 downward, thereby increasing the friction of the sheet on the conveyor belt assembly 1.

[0027] like Figure 2 As shown, the blowing and suction device 2 is an integrated blowing and suction device with the same blowing and suction port, and the blowing and suction processes of the blowing and suction device 2 can be performed alternately. The use of the same blowing and suction port allows the blowing and suction to share some components, which not only meets the blowing and suction requirements but also helps to reduce the manufacturing difficulty and cost of the blowing and suction device 2, thereby helping to further improve the applicability of the discharge device of the kaiping line.

[0028] In the actual manufacturing process, the use of a blow-and-suction integrated device with the same blowing and suction ports is not limited. A blow assembly and a suction assembly can also be used to form a blow-and-suction device 2. During operation, the blow assembly and the suction assembly are alternately activated to achieve the needs of blowing and suction, thereby meeting the needs of actual use. The present invention is not limited to the above two types of blow-and-suction devices 2. On the basis of not departing from the inventive concept of the present invention, a blow-and-suction device 2 with other structures to achieve the blowing and suction functions to form a Kaiping line discharge device also falls within the scope of protection of the present invention.

[0029] The blowing and suction device 2 is a blowing and suction device that blows air when the material is being fed to the cutting machine and sucks air when the cutting machine is cutting and / or retracting. Blowing air when the material is being fed to the cutting machine can blow air on the sheet material that passes through the cutting machine and enters the conveyor belt assembly 1, thereby preventing direct impact of the edges and corners of the sheet material and reducing friction. Sucking air when the cutting machine is shearing can help to stably limit the sheet material, thereby making the shearing process smoother and more accurate, which helps to improve the quality of shearing; and after the shearing is completed, the sheet material can be directly transferred quickly by suction, thereby meeting the demand for fast and stable output of the sheet material. Sucking air when the cutting machine is retracting can increase the friction of the cut sheet material on the conveyor belt assembly 1, thereby facilitating fast and stable transfer of the sheet material. This can help to improve the accuracy of the blowing and suction action of the blowing and suction device 2, thereby better meeting the needs of actual use.

[0030] like Figure 2 As shown, the blowing and suction device 2 includes a blowing and suction air generating device 21 and a position detecting device 22 for detecting the position of the cutting blade on the cutting machine. The blowing and suction air generating device 21 is electrically connected to the position detecting device 22. In this way, the position of the cutting blade on the cutting machine can be detected by the position detecting device 22 to accurately determine the state of the cutting machine, so that the blowing and suction air generating device 21 can blow or suck air accordingly. This can facilitate accurate and stable control of the blowing and suction generation, thereby helping to further improve the reliability and applicability of the material discharging device of the flattening line.

[0031] like Figure 2As shown, the blowing and suction generating device 21 includes a reversing valve 211, a control circuit module 212, two fans 213, and at least one blowing and suction pipe 214 capable of blowing air upward and sucking air downward. The reversing valve 211 is provided with a first connecting pipe port 2111, a second connecting pipe port 2112, and a third connecting pipe port 2113. The reversing valve 211 can make the second connecting pipe port 2112 and the third connecting pipe port 2113 alternately connected to the first connecting pipe port 2111. The first connecting pipe port 2111 is connected and communicated with the blowing and suction pipe 214. The suction port of one fan 213 is connected and communicated with the second connecting pipe port 2112, and the blowing port of the other fan 213 is connected and communicated with the third connecting pipe port 2113. The reversing valve 211 and the position detection device 22 are both electrically connected to the control circuit module 212. Such a blowing and suction gas generating device 21 is very simple and reliable, which is not only convenient for manufacturing, but also conducive to the rapid and stable realization of the demand for switching the blowing and suction process, thereby helping to further improve the applicability and reliability of the kaiping line discharging device.

[0032] like Figure 2 As shown, during the actual installation process, the blowing and suction ports of the blowing and suction air pipe 214 are directed upward, which can blow up or absorb metal sheets and metal sheets, thus meeting the needs of actual use.

[0033] like Figure 2 As shown, both fans 213 are vortex fans, which can help generate more stable and reliable blowing and suction forces, thereby helping to further improve reliability.

[0034] like Figure 2 As shown, the reversing valve 211 is a two-position three-way reversing valve. The cylinder 2114 is used on the reversing valve 211 to push its internal piston to achieve the need of switching the internal airway. In this way, the reversing valve 211 can make the second docking pipe port 2112 and the third docking pipe port 2113 alternately connected to the first docking pipe port 2111. In the actual manufacturing process, other reversing valves such as a two-position three-way electromagnetic reversing valve can also be used to meet the reversing requirements. In this way, the needs of actual use can be met. Only several requirements for achieving reversing are disclosed here. Without departing from the creative concept of the present invention, the use of other reversing valves to constitute the blowing and suction generating device 21 also falls within the scope of protection of the present invention.

[0035] In the actual manufacturing process, in addition to using the reversing valve 211 and two fans 213, the blowing and suction generating device 21 can also adopt the following structure to achieve blowing and suction: use a forward and reverse rotating fan (not shown in the figure) to replace the reversing valve 211 and the two fans 213, so that the forward and reverse rotating fan is electrically connected to the control circuit module 212, and the blowing and suction pipe 214 is docked on the forward and reverse rotating fan. By making the forward and reverse rotating fan forward and reverse, the blowing and suction pipe 214 can be used to blow or inhale, so that air blowing force or suction force can be generated on the metal sheet or metal sheet, thereby meeting the actual use needs.

[0036] The position detection device 22 is a detection module for detecting the rotational angle position of the hob shaft on the cutting machine. When the cutting machine uses the hob shaft for cutting, the position detection device 22 can be used to detect the rotational angle of the hob shaft, thereby detecting the angle of the hob blade, and can convert the detected result into a digital signal and transmit it to the control circuit module 212. The control circuit module 212 can then determine the state of the hob shaft based on the relevant digital signal and, based on the determined state, switch the reversing valve 211 to the corresponding state to cause the blowing and suction generating device 21 to blow or suction accordingly. This structure facilitates the purpose of accurately controlling the operating state of the blowing and suction generating device 21, thereby ensuring the stable and reliable operating performance of the slitting line discharge device.

[0037] The cutting machine with a hob shaft is a conventional cutting machine, and its specific structure will not be described here. It can be realized by referring to the existing cutting machine with a hob shaft.

[0038] In the actual manufacturing process, the following methods can be used to implement rotation angle detection: first, an encoder is used to form a position detection device 22, so as to detect the rotation angle of the blade on the hob shaft through the encoder, and the encoder is used to convert the relevant angle information into a digital signal and transmit it to the control circuit module 212; second, an angle sensor is used to form a position detection device 22, so as to detect the rotation angle of the blade on the hob shaft through the angle sensor, and the angle sensor is used to convert the relevant angle information into a digital signal and transmit it to the control circuit module 212; third, a combination of gears and photoelectric sensors is used, the gears are installed on the hob shaft, and the photoelectric sensor is used to record the number of rotations of the gear teeth to detect the rotation angle of the blade on the hob shaft, and the photoelectric sensor is used to convert the relevant angle information into a digital signal and transmit it to the control circuit module 212. In this way, the position detection device 22 can detect the rotation angle of the hob shaft blade and transmit the relevant angle information to the control circuit module 212 in the form of a digital signal. The control circuit module 212 then analyzes the state of the hob shaft based on the digital signal. Then, the control circuit module 212 can use the control circuit module 212 to put the reversing valve 211 into the corresponding state, thereby putting the blowing and suction generating device 21 into the corresponding blowing state or suction state, thereby achieving the purpose of accurate coordinated control. The above are only a few ways to achieve rotation angle detection and coordinated control of suction and blowing. The present invention is not limited to the above methods. Other inventive concepts that do not depart from the present invention are within the scope of protection of the present invention.

[0039] The encoder and its mounting structure, the angle sensor and its mounting structure, and the mounting structure of the gear and the photoelectric sensor all adopt conventional technical solutions, which will not be described here. For details, please refer to relevant technical literature; the control circuit module 212 can use a programmable logic controller (PLC) to implement relevant control; this can meet the needs of production and use.

[0040] The control circuit module 212 controls the cylinder 2114 of the reversing valve 211 to switch between blowing and suction, thus meeting practical requirements. After the hob blade completes a cut, it rises and then descends to prepare for the next cut. During the period between the hob blade's rise and its descent to prepare for the next cut, the metal sheet slides through the shearing machine.

[0041] During specific control, when the position detection device 22 detects that the blade of the hob shaft rises to a certain angle and then descends to the state before the next cutting, the reversing valve 211 is controlled by the control circuit module 212 to keep the blowing and suction generating device 21 in the blowing state; the blowing state is entered after the blade of the hob shaft rises to a certain angle, which can ensure that the flattening line discharge device has used suction to stably transport the previous piece of metal sheet; the blowing state is entered during the rising process of the blade of the hob shaft, which can ensure that there is a blowing effect on the conveyor belt assembly 1 before the end of the metal sheet contacts the conveyor belt assembly 1; this can avoid the end of the metal sheet directly hitting the conveyor belt assembly 1 and reduce the friction of the metal sheet on the conveyor belt assembly 1, thereby reducing the aging speed of the conveyor belt assembly 1, which can help reduce maintenance costs.

[0042] When the position detection device 22 detects that the blade of the hob shaft is at an angle close to the cutting state, the control circuit module 212 controls the reversing valve 211 to switch the blowing and suction generating device 21 to the suction state; this not only helps to stably position the metal sheet, but also increases the friction of the cut metal sheet on the conveyor belt assembly 1, thereby meeting the needs of quickly and stably conveying the metal sheet.

[0043] In actual use, there are various ways to coordinate the switching of air blowing and suction with the cutting machine's movements, which can be adjusted according to actual needs. For example, a detection probe can be used to detect the height of the cutting blade to achieve coordinated control. The above is only an introduction to one coordinated control method of the present invention and does not limit the coordinated control method. Without departing from the inventive concept of the present invention, structures that use other position detection methods to achieve coordinated control also fall within the scope of protection of the present invention.

[0044] The discharge device of the kaiping line can be used not only for discharging metal sheets, but also for discharging sheets of other materials, and has a wide range of applications.

[0045] like Figure 1 and Figure 2As shown, a wide suction port 2141 and a narrow suction port 2142 are respectively provided at both ends of the top of the suction and blowing pipe 214. The wide suction and blowing port 2141 is positioned close to the air source end of the suction and blowing pipe 214, while the narrow suction and blowing port 2142 is positioned away from the air source end of the suction and blowing pipe 214. Furthermore, the wide suction and blowing ports 2141 and the narrow suction and blowing ports 2142 are arranged side by side along the conveying direction of the conveyor belt assembly 1. This allows for the formation of a large suction and blowing zone and a small suction and blowing zone in sequence from the input end to the output end of the conveyor belt assembly 1, thereby generating successively decreasing blowing and suction forces. When the successively decreasing blowing force is generated, the end of the metal sheet is facilitated to slowly lower itself into contact with the conveyor belt assembly 1, thereby ensuring more accurate and stable contact of the metal sheet. When the suction force decreases, high and low suction zones are formed side by side. The high suction zone helps to stably position the metal sheet, significantly reducing the chances of vibration and displacement during the shearing process, as well as the chance of deformation of the metal sheet, and facilitates accurate conveying of the metal sheet. The low suction zone not only ensures stable conveying but also reduces related energy consumption, thereby reducing production costs for sheet metal processing companies.

[0046] In the actual manufacturing process, the air blowing and suction pipe 214 is not limited to having a wide air blowing and suction port 2141 and a narrow air blowing and suction port 2142. At least one air blowing and suction port can also be provided, which can also meet the needs of actual use.

[0047] like Figure 2 As shown, the wide blowing and suction opening 2141 is a circular opening, and the narrow blowing and suction opening 2142 is a flat strip opening, and the length direction of the flat strip opening is aligned with the conveying direction of the conveyor belt assembly 1. The width of the wide blowing and suction opening 2141 is also greater than that of the narrow blowing and suction opening 2142. This not only facilitates manufacturing but also helps generate reliable suction.

[0048] like Figure 3As shown, the conveyor belt assembly 1 includes a positioning frame 11 and at least one conveyor belt 12, which is wound around the positioning frame 11. The conveyor belt 12 is provided with at least one set of air holes 13. The air hole set 13 includes a plurality of blowing and suction holes 131 extending from the outer wall of the conveyor belt 12 to the inner wall of the conveyor belt 12, with each blowing and suction hole 131 arranged side by side along the circumference of the conveyor belt 12. The blowing and suction pipe 214 is arranged on the inner side of the conveyor belt 12, with the wide blowing and suction openings 2141 and narrow blowing and suction openings 2142 on the blowing and suction pipe 214 facing upward and oriented toward the corresponding blowing and suction holes 131. This conveyor belt assembly 1 is very simple and reliable, not only facilitating manufacture but also ensuring highly stable conveying. By arranging the blowing and suction pipe 214 on the inner side of the conveyor belt 12, the kaiping line discharge device has a compact structure, thereby increasing its scope of application. By opening an air hole group 13 on the conveyor belt 12 and making the wide blowing and suction port 2141 and the narrow blowing and suction port 2142 face the blowing and suction air holes 131 at the corresponding positions, it is beneficial to achieve a very stable and reliable blowing and suction effect, thereby helping to further improve the performance of the discharge device of the kaiping line.

[0049] Figure 1 and Figure 3 Only some of the blowing and suction holes 131 on the upper half of the conveyor belt 12 are drawn. In fact, a number of blowing and suction holes 131 are arranged side by side at equal intervals in the circumferential direction of the conveyor belt 12, which can meet normal usage needs.

[0050] like Figure 1 and Figure 3 As shown, the positioning frame 11 is provided with a support plate 14 positioned between the upper half of the conveyor belt 12 and the blowing and suction pipes 214. The support plate 14 is provided with at least one vent hole 141 corresponding to the wide blowing and suction openings 2141 and the narrow blowing and suction openings 2142. The support plate 14 facilitates supporting the upper half of the conveyor belt 12, which not only makes the conveyor belt 12 more stable and reliable in supporting the metal sheets, but also helps generate more stable friction, thereby further improving the accuracy and stability of the metal sheet transfer.

[0051] like Figure 3 As shown, in the actual manufacturing process, a number of vent holes 141 can be opened, and the vent holes 141 can be arranged side by side along the conveying direction of the conveyor belt 12. The first few vent holes 141 can be connected to the wide blowing and suction port 2141, and the other vent holes 141 can be connected to the narrow blowing and suction port 2142. This can well meet the needs of actual use.

[0052] like Figure 3As shown, the conveyor belt 12 and the supporting plate 14 are both arranged horizontally, and the supporting plate 14 is tilted downwards towards the output and input ends of the conveyor belt 12. This can prevent the supporting plate 14 from scratching the conveyor belt 12, thereby enabling the conveyor belt 12 to perform its conveying function very stably.

[0053] like Figure 3 As shown, the blowing and suction holes 131 are strip-shaped holes, and the length direction of the radial cross-section of the blowing and suction holes 131 is arranged at an angle relative to the conveying direction of the conveyor belt 12. The vent holes 141 are strip-shaped holes, and the length direction of the radial cross-section of the vent holes 141 is arranged at an angle relative to the conveying direction of the conveyor belt 12. The inclination direction of the vent holes 141 is also opposite to that of the blowing and suction holes 131. This helps the blowing and suction holes 131 generate a continuous and stable suction force, thereby further improving the reliability and applicability of the kaiping line discharge device.

[0054] like Figure 3 As shown, in the actual manufacturing process, the vent holes 141 and the blowing and suction holes 131 can be made into waist-shaped holes, which not only makes it easier to open them, but also reduces the impact of the hole opening on the structural strength of related components.

[0055] like Figure 3 As shown, there are two conveyor belts 12, arranged side by side perpendicular to their conveying direction. There are two blowing and suction pipes 214, each located inside the two conveyor belts 12. This eliminates the need for a wide conveyor belt 12 to support wide metal sheets, thereby reducing material usage during manufacturing and ensuring smooth operation of the conveyor belts 12. Furthermore, both conveyor belts 12 generate a very stable and reliable friction force, ensuring the high reliability and applicability of the kaiping line discharge device.

[0056] like Figure 3 As shown, in the actual manufacturing process, the two conveyor belts 12 can be wound around the same driving shaft 111, which can meet the demand for synchronous movement and thus ensure very stable performance.

[0057] like Figures 1 to 4 As shown, in the actual manufacturing process, the air suction and blowing pipe 214 can adopt either an integrated pipe structure or an assembled pipe structure. The integrated pipe structure is composed of a single pipe; the assembled pipe structure is composed of two or more pipes. In this case, the wide air suction and blowing port 2141 and the narrow air suction and blowing port 2142 can be provided on the same pipe or on different pipes. Both of the above air suction and blowing pipes 214 can meet the needs of actual use.

[0058] like Figure 2 and Figure 4 As shown, the two blowing and suction pipes 214 are connected to the same butt joint 215, and the butt joint 215 is connected to the first butt joint port 2111. In this way, the two blowing and suction pipes 214 can stably generate blowing or suction at the same time, thereby helping to further improve the reliability of the discharge device of the slitting line.

[0059] During actual use, the blowing and suction functions of the blowing and suction device 2 are coordinated with the cutting action of the shearing machine. When the metal sheet is transported to the flattening line discharge device through the shearing machine, the blowing and suction device 2 blows air, which can prevent the sharp edges of the metal sheet from scratching the conveyor belt 12; after the metal sheet is transported, the end of the metal sheet can be directly cut by the shearing machine, and the blowing and suction device 2 can be used to suction air to enhance the positioning of the end of the metal sheet; after the shearing machine completes cutting, the suction of the blowing and suction device 2 is used to make the friction of the metal sheet on the conveyor belt 12 in a relatively large state, which can help the conveyor belt 12 to quickly carry away the metal sheet. Such a process does not require the use of rollers to clamp and remove the metal sheet, which can avoid the generation of indentations, which not only helps to improve the production quality of the metal sheet, but also greatly reduces the probability of defective products and waste.

[0060] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, and these all fall within the scope of protection of the present invention.
