Description

Technical Field

[0001] This invention relates to the field of tinplate cutting technology, and more particularly to a tinplate cutting and edge grinding device. Background Technology

[0002] In the tinplate processing industry, slitting is a crucial process connecting raw materials and downstream products. By cutting coils or sheets of tinplate into specific sizes that meet subsequent forming requirements, the precision of subsequent processes such as can making and stamping can be ensured, while reducing raw material waste and improving production efficiency. As the intelligent manufacturing equipment industry upgrades towards high efficiency, continuous operation, and intelligence, tinplate processing production lines place higher demands on the performance of core equipment. Although traditional tinplate cutting equipment can slitting simultaneously with multiple blades, it often uses a single-blade design. When the blades wear out and need replacement or maintenance, The machine must be stopped, causing production interruption and severely impacting the continuous operating efficiency of the production line. Furthermore, the long-term operation of a single set of cutters is prone to frictional heat generation, leading to increased cutting edge temperature. This not only accelerates cutter wear but may also affect the smoothness and finish of the tinplate cutting edges due to high temperatures. In addition, the existing equipment requires individual inspection of both sides of each cutter, often necessitating multiple inspection heads. This results in a complex structure and low inspection efficiency. If cutter malfunctions are not detected in time, it can easily lead to an increased rate of defective products. At the same time, manual inspection and replacement are not only time-consuming but also further increase the risk of downtime, making it difficult to balance production continuity, cutter life, and cutting quality.

[0003] To address the above problems, this invention proposes a tinplate cutting and edge grinding device. Summary of the Invention

[0004] The purpose of this invention is to solve the problems of traditional tinplate cutting equipment, which mostly adopts a single set of blades. When the blades are worn and need to be replaced or maintained, the machine must be stopped, resulting in production interruption. In addition, the existing equipment requires the blade inspection to be carried out on both sides of each blade separately, which requires multiple inspection heads, resulting in complex structure and low inspection efficiency. Therefore, this invention proposes a tinplate cutting and edge grinding device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

The rubber protrusion is adapted to the positioning port, and the rotating shaft is rotatably mounted on the guide seat through a bearing.

[0014] Preferably, the tool conversion assembly includes two switching shafts, both ends of which are rotatably mounted on two conveyor frames via bearings. The two switching shafts are connected by a conveyor structure, and one of the switching shafts is fixedly connected to the output shaft of a first motor, which is mounted on the conveyor frame.

[0015] Two fixed sleeves are installed on the switching shaft. The two adjacent fixed sleeves are provided with a first switching chain belt, and both fixed sleeves are connected to the connecting plate through bearings.

[0016] Preferably, the auxiliary drive assembly includes an auxiliary shaft, which is rotatably mounted on two mounting plates via two bearings. Each pair of diagonally opposite mounting plates is mounted on the same first switching chain. One end of the auxiliary shaft is fixedly connected to a driven gear, which can mesh with the drive structure by changing its position. The drive structure is mounted on the conveyor frame.

[0017] Preferably, each set of the cutting components comprises multiple components, each including a blade holder and two blade sleeves.

[0020] Compared with the prior art, the present invention provides a tinplate cutting and edge grinding device, which has the following beneficial effects:

[0021] 1. This tinplate cutting and edge-grinding equipment allows for adjustment of the blade spacing of the cutting components via a blade adjustment assembly, meeting the cutting needs of tinplate with different spacings. Furthermore, based on the blade spacing adjustment, the blade switching assembly enables the interchange of two sets of cutting components. The blade replacement process does not require machine downtime, avoiding production interruptions caused by blade changes in traditional single-blade equipment. The blades can be used in a single set or switched between two sets. The switching interval allows the blades to cool down, ensuring stable cutting. This flexible conversion design fully demonstrates the significant advantages of high efficiency and flexibility in the intelligent manufacturing equipment industry.

[0022] 2. This tinplate cutting and edge-grinding equipment uses two sets of cutting components that can be switched to operate in a cooling zone. This cooling component can quickly lower the temperature, preventing overheating of the cutting edge caused by prolonged operation of a single set of blades, thus slowing down the wear rate and extending the blade's lifespan. During the cooling process, a linear drive component drives an adjustment and detection component, which can move to both sides of the exhaust hood and automatically rotate. This allows for multi-faceted automatic detection of the blade. When problems such as excessive wear or edge damage are detected, an alarm can be automatically issued to promptly notify the staff to replace the blade, preventing the faulty blade from continuing to operate and cutting defective products.

[0023] 3. This tinplate cutting and edge-grinding equipment can automatically switch between two sets of cutting components through a tool switching component and a tool adjustment component. After switching, the cutting component automatically continues the cutting line to cut tinplate. The non-stop switching function provides an operation window for blade heat dissipation and inspection. When switching to the standby cutting component, the idle blade has time to dissipate heat and can also easily and quickly dissipate heat through the cooling component. The linear drive component, together with the adjustment and detection component, can achieve comprehensive blade inspection without occupying extra production time, ensuring that inspection and heat dissipation do not affect the continuity of production. The switching heat dissipation and inspection functions provide a prerequisite for non-stop switching. By regularly inspecting the idle blades, potential blade failures can be detected in advance and replaced in time, avoiding the standby blades being unable to be used due to failure. This ensures that both sets of blades are always in a usable state and guarantees the reliable implementation of the non-stop switching function. Attached Figure Description

Detailed Implementation

[0037] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0039] Example 1: Refer to Figures 1-4 and Figures 9-12 A tinplate cutting and edge grinding device includes a cutting mechanism 100, and a tool maintenance mechanism 200 is provided on the cutting mechanism 100.

[0040] The cutting mechanism 100 includes a base plate 101. A grinding structure 105 and two conveying rollers 104 are mounted above the base plate 101. The two conveying rollers 104 transport the tinplate and support it, ensuring smooth transport. The grinding structure 105 grinds the edges of the cut tinplate. Two conveyor frames 102 are mounted on the base plate 101. Two toothed rods 110 are mounted on one of the conveyor frames 102. Two tool conversion assemblies 103 are arranged between the two conveyor frames 102. The system includes two switching shafts 1032, each with its ends rotatably mounted on two conveyor frames 102 via bearings. The two switching shafts 1032 are connected by a conveyor structure 1034, which can use chain or belt drive to achieve synchronous rotation of the two switching shafts 1032. One switching shaft 1032 is fixedly connected to the output shaft of a first motor 1031, which is mounted on the conveyor frame 102. Two fixing sleeves 1036 are mounted on the switching shaft 1032. Adjacent fixing sleeves 1036... A first switching chain 1033 is provided, which drives two auxiliary drive components 108 to exchange, facilitating the replacement of two sets of cutting components 107. Both fixed sleeves 1036 are connected to connecting plates 1035 via bearings. Auxiliary drive components 108 are provided on the diagonally opposite upper and lower sides of the tool conversion component 103. Each auxiliary drive component 108 includes an auxiliary shaft 1081, which is rotatably mounted on two mounting plates 1083 via two bearings. Each pair of diagonally opposite mounting plates 1083... Mounting plate 1083 can be mounted on the first switching chain 1033 as needed by bolt assembly. One end of auxiliary shaft 1081 is fixedly connected to driven gear 1082. Driven gear 1082 can mesh with drive structure 109 by changing position. Drive structure 109 is a drive source consisting of motor and drive gear. Running the motor can drive drive gear 1082 to drive cutting assembly 107 to cut tinplate. Drive structure 109 is mounted on conveyor frame 102.

[0041] The tool conversion assembly 103 drives the auxiliary drive assembly 108 to move, enabling the driven gear 1082 of the auxiliary drive assembly 108 to mesh with the rack 110. The driven gear 1082 translates and transmits power to the rack 110, thus allowing the cutting assembly 107 to smoothly perform cutting operations. The tool conversion assembly 103 is equipped with a tool adjustment assembly 106, which includes a telescopic frame 1063 and multiple adjustment sleeves 1065. The telescopic frame 1063 is hinged to multiple chain plates 1066 and multiple first sliders 1062. A first slide groove 1064 is formed on the chain plate 1066, and a first slider 1062 is slidably connected within the first slide groove 1064. The first slider 1062 moves through the first slide groove 1064. The sliding mechanism 1064 allows the telescopic frame 1063 to extend and retract smoothly. One of the first sliders 1062 is fixedly connected to one end of an electric cylinder 1061, which is installed in the first slide groove 1064. Two adjusting sleeves 1065 are rotatably mounted at both ends of the chain plate 1066 via bearings. The adjusting sleeves 1065 can rotate smoothly via the bearings, thus enabling the second switching chain belt 1067 to run smoothly. The second switching chain belt 1067 is mounted on both adjusting sleeves 1065. A tool holder 1071 is mounted on the second switching chain belt 1067. The tool holder 1071 can be bolted to the second switching chain belt 1067, allowing the second switching chain belt 1067 to operate. The tool adjustment assembly 106 can drive two sets of cutting components 107 for replacement. An adjusting sleeve 1065 is slidably connected to a switching shaft 1032. Both the switching shaft 1032 and the adjusting sleeve 1065 are polygonal structures. The adjusting sleeve 1065 can slide on the switching shaft 1032, thus allowing smooth adjustment of the cutting components 107. The polygonal structure of both the adjusting sleeve 1065 and the switching shaft 1032 ensures that the switching shaft 1032 can smoothly drive the adjusting sleeve 1065 to rotate. Two sets of cutting components 107 are provided on the tool adjustment assembly 106. These two sets of cutting components 107 are respectively mounted on two auxiliary drive assemblies 108. Each set of cutting components 107 includes multiple cutting tool holders 1071 and two cutting tool sleeves 1072. Both blade holders 1072 are rotatably mounted on two blade holders 1071 via bearings. The blade holders 1072 can rotate stably via the bearings, keeping the blades 1073 rotating stably. The blades 1073 are mounted on the blade holders 1072. The blade holders 1072 are slidably connected to the auxiliary shaft 1081. The auxiliary shaft 1081 has a polygonal structure, and the shape of the blade holders 1072 is adapted to the shape of the auxiliary shaft 1081. The blade holders 1072 can slide and move on the auxiliary shaft 1081, so that the spacing between the blades 1073 can be easily adjusted. Since the blade holders 1072 and the auxiliary shaft 1081 have polygonal structures, the rotation of the auxiliary shaft 1081 drives the blade holders 1072 to rotate, thereby allowing the blades 1073 to smoothly cut tinplate.

[0042] In this embodiment: the first slider 1062 can be moved by the electric cylinder 1061, which causes the telescopic frame 1063 to extend and retract to adjust the distance of the chain plate 1066, thereby adjusting the blade spacing of the cutting component 107 to meet the cutting requirements of different spacings of tinplate. Based on the distance adjustment, the first motor 1031 drives the switching shaft 1032 to rotate. The switching shaft 1032 drives the first switching chain belt 1033 and the second switching chain belt 1067 to move, thereby realizing the replacement of two sets of cutting components 107. The process of changing the blade 1073 does not require stopping the machine, avoiding the production interruption caused by blade changing in traditional single-blade equipment. The blade 1073 can be used in a single set or switched between two sets. The switching gap allows the blade 1073 to have a cooling time, ensuring stable cutting. This flexible conversion design fully demonstrates the significant advantages of high efficiency and flexibility in the intelligent manufacturing equipment industry.

[0043] Example 2: Refer to Figures 5-8 A tinplate cutting and edge-grinding device includes a blade maintenance mechanism 200. The blade maintenance mechanism 200 includes an outer frame 201, which is mounted on a base plate 101. Cooling components 202 are provided on both the upper and lower sides of the outer frame 201. The cooling components 202 include a fan 2021, the air outlet of which is connected to an exhaust hood 2022. The fan 2021 can accelerate the airflow output through the exhaust hood 2022, thereby rapidly cooling the blade 1073. The exhaust hood 2022 is fixedly connected to two electric push rods 204, which are mounted on the outer frame 201. The position of the exhaust hood 2022 can be adjusted by the electric push rods 204, so that the height of the exhaust hood 2022 can be raised to facilitate the replacement of the blade 1073. An alarm 205 is installed on the outer frame 201, which can provide an alarm reminder when the blade 1073 is damaged.

[0044] A linear drive assembly 203 is provided on the cooling assembly 202. The linear drive assembly 203 includes a second motor 2031, which is mounted on the exhaust hood 2022. The output shaft of the second motor 2031 is fixedly connected to a screw 2032. The screw 2032 is rotatably mounted on the exhaust hood 2022 via a bearing. One end of the screw 2032 is fixedly connected to a first gear 2033. The first gear 2033 drives the driven gear 1082 to keep the blade 1073 rotating for cooling. A nut is threaded onto the screw 2032. 2035, a guide seat 2034 is installed on the nut 2035. The two ends of the guide seat 2034 are slidably connected to two guide holes opened on the exhaust hood 2022. The guide holes guide the guide seat 2034 and keep it sliding stably. The guide seat 2034 has four positioning holes 2036. An adjustable detection component 206 is provided on the linear drive assembly 203. The adjustable detection component 206 includes a toothed plate 2063. The toothed plate 2063 has a dovetail groove 2062. The dovetail groove 2062 and the dovetail slider 2022 are connected. 061 Sliding connection, dovetail slider 2061 is fitted into dovetail groove 2062, thereby supporting toothed plate 2063, and toothed plate 2063 can slide smoothly on dovetail slider 2061 through dovetail groove 2062. Dovetail slider 2061 is fixedly connected to guide seat 2034. Toothed plate 2063 meshes with arc-shaped tooth segment 2064, and moves to the two side walls of exhaust hood 2022 through toothed plate 2063, so that toothed plate 2063 can move alternately, and toothed plate 2063 and arc-shaped tooth segment 2064 can switch and adjust the monitor 2065 in multiple directions, from To facilitate comprehensive inspection of the blade 1073 by the monitor 2065, an arc-shaped tooth segment 2064 is provided on the monitor 2065. A rotating shaft 2066 and a rubber protrusion 2067 are fixedly connected to both sides of the monitor 2065. When the monitor 2065 is adjusted, the rubber protrusion 2067 can be inserted into the positioning port 2036, thereby maintaining the angle of the monitor 2065 and preventing the angle of the monitor 2065 from changing. The rubber protrusion 2067 is adapted to the positioning port 2036, and the rotating shaft 2066 is rotatably mounted on the guide seat 2034 through a bearing.

[0045] In this embodiment: By switching between the two sets of cutting components 107, the switched cutting component 107 is placed in the cooling zone, where it can be rapidly cooled by the cooling component 202. This prevents overheating of the cutting edge caused by prolonged operation of a single set of blades 1073, slows down the wear rate of the blades 1073, and extends their service life. During the cooling process, the second motor 2031 drives the screw 2032 to rotate. The screw 2032, through the nut 2035, drives the guide seat 2034 to move, causing the guide seat 2034 to adjust and detect. The component moves to detect the blade 1073. When the toothed plate 2063 moves to the side wall of the exhaust hood 2022, the toothed plate 2063 is displaced by force and drives the arc-shaped toothed segment 2064. The arc-shaped toothed segment 2064 drives the monitor 2065 to rotate, thereby enabling multi-face automatic detection of the blade 1073. When the blade 1073 is found to have excessive wear or missing cutting edge, an alarm will be automatically issued to remind the staff to replace it in time, so as to prevent the faulty blade 1073 from continuing to work and cutting defective products.

[0046] Example 3: Reference Figures 1-2 , Figures 4-6 and Figure 11 A tinplate cutting and edge-grinding device includes a cutting mechanism 100, a tool maintenance mechanism 200 on the cutting mechanism 100, a base plate 101, two conveyor frames 102 on the base plate 101, two racks 110 on one of the conveyor frames 102, two tool conversion assemblies 103 between the two conveyor frames 102, auxiliary drive assemblies 108 on the diagonally opposite upper and lower sides of the tool conversion assembly 103, the tool conversion assembly 103 drives the auxiliary drive assembly 108 to move, so that the driven gear 1082 of the auxiliary drive assembly 108 can mesh with the rack 110, and a tool adjustment assembly 106 is provided on the tool conversion assembly 103, and two sets of cutting assemblies 107 are provided on the tool adjustment assembly 106, which are respectively set on the two auxiliary drive assemblies 108.

[0047] The tool maintenance mechanism 200 includes an outer frame 201, which is mounted on a base plate 101. Cooling components 202 are provided on both the upper and lower sides of the outer frame 201. A linear drive component 203 is provided on the cooling component 202, and an adjustable detection component 206 is provided on the linear drive component 203.

[0048] In this embodiment: the tool switching component 103, in conjunction with the tool adjustment component 106, can automatically switch between two sets of cutting components 107. After switching, the cutting component 107 automatically continues the cutting line to cut tinplate. The non-stop switching function provides an operating window for heat dissipation and inspection of the blade 1073. When switching to the standby cutting component 107, the idle blade 1073 has time to dissipate heat, and can also achieve rapid heat dissipation through the cooling component 202. Furthermore, the linear drive component 203, in conjunction with the adjustment and detection component, enables comprehensive inspection of the blade 1073 without occupying additional production time, ensuring that inspection and heat dissipation do not affect production continuity. The switching of heat dissipation and inspection functions provides… The non-stop replacement provides a prerequisite guarantee. By regularly inspecting the idle blades 1073, potential faults in the blades 1073 can be detected in advance and replaced in time, avoiding the inability of the spare blades 1073 to be used due to faults. This ensures that both sets of blades 1073 are always in a usable state, guaranteeing the reliable implementation of the non-stop replacement function. At the same time, the efficient detection design of a single detection head reduces the complexity of the equipment structure and lowers the difficulty of linking the switching and detection of the two sets of blades 1073. This makes cutting, switching, heat dissipation, detection and blade replacement form a closed loop process, which not only ensures continuous production, but also extends the life of the blades 1073, reduces the defect rate, and achieves simultaneous improvement in production efficiency, cutting quality and equipment stability.

[0049] Working principle: When performing tinplate cutting, the blade distance is pre-adjusted. The first slider 1062 is moved by the electric cylinder 1061. The first slider 1062 drives the telescopic frame 1063 to extend and retract, so that the telescopic frame 1063 can drive the chain plate 1066 to move. The chain plate 1066 drives the cutting component 107 to adjust the spacing through the adjusting sleeve 1065 and the second switching chain belt 1067. After adjustment, the driven gear 1082 is driven by the drive structure 109. The driven gear 1082 drives the auxiliary shaft 1081 to rotate. The auxiliary shaft 1081 drives the fixed sleeve 1036 to rotate. The fixed sleeve 1036 drives the blade 1073 to rotate. The rotation of the blades 1073 on the upper and lower sides can perform multi-segment cutting on the conveyed tinplate.

[0050] When it is necessary to replace or switch between two sets of blades 1073, the first motor 1031 drives the switching shaft 1032 to rotate. The switching shaft 1032 drives the fixed sleeve 1036 and the first switching chain 1033 to run. At the same time, the adjusting sleeve 1065 drives the second switching chain 1067 to run, causing the cutting component 107 to move horizontally. The driven gear 1082 and the rack 110 drive the auxiliary drive component 108 to keep rotating, so that the blade 1073 moves horizontally to perform the cutting operation. The cut tinplate is then edged by the edge grinding structure 105.

[0051] After the two sets of blades 1073 are switched, the switched blades 1073 continue to cut along the cutting line. The other set of blades 1073 corresponds to the exhaust hood 2022, and the driven gear 1082 is engaged with the first gear 2033. At this time, the cooling component 202 cools the blades 1073 and controls the second motor 2031 to drive the screw 2032 to rotate. The screw 2032 drives the auxiliary drive component 108 to rotate through the first gear 2033, so that the blades 1073 keep rotating for cooling.

[0052] Furthermore, the operation of the screw 2032 also drives the nut 2035 to move, the nut 2035 drives the guide seat 2034 to move, and the guide seat 2034 drives the adjustable detection component 206 to move, so that the monitor 2065 performs the blade 1073 detection operation. When one end of the toothed plate 2063 contacts the side wall of the exhaust hood 2022, the toothed plate 2063 is pushed and moves and is driven by the arc-shaped tooth segment 2064, so that the monitor 2065 automatically turns, and the rubber protrusion 2067 is inserted into another positioning port 2036. Then the second motor 2031 rotates in the opposite direction, so that the monitor 2065 detects the other side of the blade 1073, thus detecting the blade 1073. If the blade 1073 has a problem, the tool holder 1071 can be disassembled and installed for replacement.
