Description

Technical Field

[0001] The invention relates to the technical field of iron plate labeling, and in particular to a device for attaching specification labels to tinplate sheets. Background Art

[0002] Tinplate is a cold-rolled tin-plated steel sheet. It is a cold-rolled low-carbon steel sheet or steel strip plated with pure tin on both sides of the tinplate. It can prevent corrosion and rust. Tinplate has high strength and good ductility. Thanks to its good corrosion resistance, tinplate is the preferred container for canned packaging. Secondly, due to its beautiful metal appearance, it is also often used to make collectibles. The size of the tinplate sheet needs to be measured when it leaves the factory and the specification label should be affixed according to the size to facilitate subsequent use and sales. Usually, the label is affixed manually. At the same time, the length, width and height measurement of the tinplate sheet and the labeling are usually carried out separately. The size is measured manually first, and then the data is entered, and then the label is affixed. The operation efficiency is low. The labeling machine in the prior art can realize the conventional labeling function. However, the labels usually posted must be of uniform specifications. It is impossible to achieve multiple postings for parts with differences. At the same time, it is impossible to perform continuous labeling operations, and the degree of automation is not high. Summary of the invention

[0003] In view of the above technical problems, the technical solution adopted by the present invention is: a device for pasting specification labels on tinplate sheets, including a conveying device, the conveying device includes a conveying frame, a feeding ramp is fixedly installed on the conveying frame, the conveying device is used to drive the tinplate sheets to circulate, the conveying device is provided with a plate feeding device and a printing device, the plate feeding device includes a plate placing box, the plate placing box is fixedly installed on the feeding ramp, the plate feeding device is used to feed the tinplate sheets, the printing device includes a fixedly installed inkjet printer, the inkjet printer is fixedly installed on the conveying frame, and the printing device is used to label the tinplate sheets.

[0004] Furthermore, the conveying device includes a driving wheel and a driven wheel rotatably mounted on a conveying frame, a docking gear is fixedly mounted on the driving wheel, a transmission belt is wrapped around the driving wheel and the driven wheel, and an upper detection mechanism, a width detection mechanism and a downward pressure mechanism are provided on the conveying frame.

[0005] Furthermore, the upper detection mechanism includes a measuring electric cylinder fixedly mounted on a conveying frame, a measuring frame fixedly mounted on the top of the measuring electric cylinder, a guide slide fixedly mounted on the conveying frame, a thickness sensor fixedly mounted on the guide slide, a sliding column slidably mounted on the measuring frame, the sliding column and the guide slide slidably mounted, a contact head fixedly mounted on the sliding column, an extrusion spring is arranged between the contact head and the measuring frame, a length sensor fixedly mounted on the measuring frame, a length trapezoidal block slidably mounted on the measuring frame, and a long spring is arranged between the length trapezoidal block and the measuring frame.

[0006] Furthermore, the width detection mechanism includes a sliding frame slidably mounted on the conveying frame, a trapezoidal block is fixedly mounted on the sliding frame, a width sensor is fixedly mounted on the feed ramp, and a side spring is arranged between the sliding frame and the feed ramp.

[0007] Furthermore, the pressing mechanism includes a pressure plate electric cylinder fixedly mounted on the conveying frame, a pressure plate is fixedly mounted on the top of the pressure plate electric cylinder, an outer frame is fixedly mounted on the pressure plate, a plurality of rotating teeth are rotatably mounted on the outer frame, and a bent tooth spring is arranged between the rotating teeth and the outer frame.

[0008] After the tinplate sheet enters the feed ramp, it falls onto the trapezoidal block and the transmission belt. At this time, the pressure plate electric cylinder extends and descends, driving the pressure plate and the outer frame to descend. The pressure plate descends to press the tinplate sheet downward, the trapezoidal block is pushed outward, and the side spring is compressed. When the pressure plate presses the tinplate sheet between the trapezoidal block and the conveyor frame, the trapezoidal block is tensioned by the side spring, and the position of the sliding frame is measured by the width sensor to obtain the width of the tinplate sheet, and the measurement data is fed back to the inkjet printer.

[0009] When the pressure plate descends, it will drive the outer frame down, thereby driving the rotating gear down. When the outer frame descends, the rotating gear will not drive the docking gear to rotate. The rotating gear rotates relative to the outer frame, and the bent tooth spring is compressed; when the pressure plate electric cylinder rises, it drives the pressure plate and the outer frame to rise. At this time, the rising rotating gear drives the docking gear to rotate, thereby driving the driving wheel to rotate, and drives the tinplate sheet forward one station through the transmission belt, that is, to the bottom of the contact head. The tinplate sheet originally located under the contact head arrives between the conveyor frame and the length trapezoidal block.

[0010] When the pressure plate electric cylinder extends, the measuring electric cylinder extends, driving the measuring frame to descend. The descent of the measuring frame drives the sliding column and the contact head to descend. When the contact head contacts the tinplate sheet below, the position of the sliding column is detected by the thickness sensor to obtain the thickness of the tinplate sheet, and the measurement data is fed back to the inkjet printer. When the contact head contacts the tinplate sheet, the measuring frame continues to descend, the extrusion spring will be compressed, but the distance between the sliding column and the thickness sensor remains unchanged.

[0011] When the measuring frame descends, the length trapezoidal block will be driven down. After the length trapezoidal block contacts the tinplate sheet between the conveying frame and the length trapezoidal block, the tinplate sheet will push the length trapezoidal block to slide outward, and the long spring will be compressed. When the measuring frame descends to the lowest position, the position of the length trapezoidal block is detected by the length sensor to obtain the length of the tinplate sheet. The length of the tinplate sheet is usually within a certain range. If the length is too long or too short, it cannot be measured, that is, the length trapezoidal block does not move horizontally during the descent, or when it moves to the extreme position, the length sensor feeds back unqualified data, and the measurement data is fed back to the inkjet printer.

[0012] Furthermore, the plate feeding device includes a pressure slide slidably mounted on the plate box, a baffle rod slidably mounted on the pressure slide, an external spring is arranged between the pressure slide and the baffle rod, the baffle rod is slidably mounted on the plate box, a lower pressure column is fixedly mounted on the pressure slide, a pressure plate is fixedly mounted on the lower pressure column, a lower pressure spring is arranged between the pressure plate and the plate box, a number of tinplate sheets are placed between the pressure plate and the plate box, and are pressed by the pressure plate and the lower pressure spring, a bidirectional motor is fixedly mounted on the pressure plate, and a friction wheel is fixedly mounted on the motor shaft of the bidirectional motor.

[0013] Furthermore, the barrier rod is provided with an inner slope surface.

[0014] Put several tinplate sheets between the pressing plate and the plate box, and press them down with the pressing spring. When feeding is needed, the bidirectional motor rotates to drive the friction wheel to rotate. The friction wheel pushes the tinplate sheets outward through friction. The tinplate sheets contact the baffle rod, and the baffle rod is pressed downward through the inner slope surface. The outer spring is stretched, and the tinplate sheets fall into the feeding slope bucket. The tinplate sheets are intermittently pushed into the feeding slope bucket.

[0015] As the number of tinplate sheets decreases, the press slide and the press plate will continue to descend, the baffle rod and the tinplate sheets will descend synchronously, and the baffle rod and the tinplate sheets to be discharged will always maintain the same height.

[0016] Furthermore, the printing device includes a side plate fixedly installed on the conveying frame, a labeling electric cylinder fixedly installed on the conveying frame, a labeling head fixedly installed on the top of the labeling electric cylinder, a sleeve and a driving shaft rotatably installed on the conveying frame, a lower wheel fixedly installed on the driven wheel, an inclined transmission wheel wrapped around the lower wheel and the driving shaft, a label belt installed outside the sleeve, the other end of the label belt is fixed on the driving shaft, an ejection electric cylinder fixedly installed on the conveying frame, a push plate fixedly installed on the top of the push-out electric cylinder, and the push plate is slidably installed with the conveying frame.

[0017] When the length, width and height of the tinplate sheet are measured, the information is recorded in the inkjet printer, the push-out electric cylinder extends to drive the push plate to slide in the conveyor frame, and the tinplate sheet is pushed to the side plate through the push plate. When the transmission belt rotates, it will drive the lower wheel to rotate, thereby driving the active shaft to rotate through the inclined transmission wheel, thereby driving the label belt to move. There are several strip patches on the label belt. The size information of the tinplate sheet is printed on the strip patches of the label belt through the inkjet printer. The label belt moves synchronously with the transmission belt. When the tinplate sheet is pushed to the side plate, its corresponding label is just above it, and the labeling electric cylinder extends to press the strip patches on the label belt onto the tinplate sheet and stick them on the tinplate sheet.

[0018] Compared with the prior art, the present invention has the following beneficial effects: (1) the width detection mechanism provided in the present invention measures and records the width of the tinplate sheet, and measures and records the thickness and length of the tinplate sheet through the upper detection mechanism, and then synchronizes the recorded data to the inkjet printer, and the specification model is sprayed onto the label tape through the inkjet printer, and the specification label is affixed to the tinplate sheet through the labeling electric cylinder, with a high degree of automation; (2) the conveying device provided in the present invention drives the tinplate sheet to advance one station at a time, and the tinplate sheet is first measured for width, and then for thickness and length, and each station is measured once, and finally the comprehensive measurement of the three data is completed; (3) the plate feeding device provided in the present invention can accommodate multiple tinplate sheets at a time, and feed the tinplate sheets into the feeding ramp bucket intermittently in sequence, so as to realize automatic intermittent feeding, with a high degree of automation.

[0030] like Figure 2-Figure 4As shown, the upper detection mechanism includes a measuring electric cylinder 112 fixedly mounted on the conveying frame 101, a measuring frame 114 is fixedly mounted on the top of the measuring electric cylinder 112, a guide slide 118 is fixedly mounted on the conveying frame 101, a thickness sensor 119 is fixedly mounted on the guide slide 118, a sliding column 120 is slidably mounted on the measuring frame 114, the sliding column 120 is slidably mounted with the guide slide 118, a contact head 122 is fixedly mounted on the sliding column 120, an extrusion spring 121 is arranged between the contact head 122 and the measuring frame 114, a length sensor 117 is fixedly mounted on the measuring frame 114, a length trapezoidal block 115 is slidably mounted on the measuring frame 114, and a long spring 116 is arranged between the length trapezoidal block 115 and the measuring frame 114.

[0031] like Figure 2-Figure 4 As shown, the width detection mechanism includes a sliding frame 110 slidably mounted on the conveying frame 101, a trapezoidal block 111 is fixedly mounted on the sliding frame 110, a width sensor 107 is fixedly mounted on the feed ramp 108, and a side spring 109 is arranged between the sliding frame 110 and the feed ramp 108.

[0032] like Figure 2-Figure 4 As shown, the pressing mechanism includes a pressing plate electric cylinder 113 fixedly mounted on the conveying frame 101, a pressing plate 123 is fixedly mounted on the top of the pressing plate electric cylinder 113, an outer frame 124 is fixedly mounted on the pressing plate 123, a plurality of rotating teeth 125 are rotatably mounted on the outer frame 124, and a bent tooth spring 105 is arranged between the rotating teeth 125 and the outer frame 124.

[0033] After the tinplate sheet 210 enters the feed ramp 108, it falls onto the trapezoidal block 111 and the transmission belt 106. At this time, the pressure plate electric cylinder 113 extends and descends, driving the pressure plate 123 and the outer frame 124 to descend. The pressure plate 123 descends to press the tinplate sheet 210 downward, the trapezoidal block 111 is pushed outward, and the side spring 109 is compressed. When the pressure plate 123 presses the tinplate sheet 210 between the trapezoidal block 111 and the conveyor frame 101, the trapezoidal block 111 is tensioned by the side spring 109, and the position of the sliding frame 110 is measured by the width sensor 107, thereby obtaining the width of the tinplate sheet 210, and the measurement data is fed back to the inkjet printer 301.

[0034] When the pressing plate 123 descends, it will drive the outer frame 124 to descend, thereby driving the rotating gear 125 to descend. When the outer frame 124 descends, the rotating gear 125 will not drive the docking gear 103 to rotate. The rotating gear 125 rotates relative to the outer frame 124, and the bent tooth spring 105 is compressed; when the pressing plate electric cylinder 113 rises, it drives the pressing plate 123 and the outer frame 124 to rise. At this time, the rotating gear 125 rises and drives the docking gear 103 to rotate, thereby driving the driving wheel 102 to rotate, and drives the tinplate sheet 210 to advance one station through the transmission belt 106, that is, to the bottom of the contact head 122. The tinplate sheet 210 originally located below the contact head 122 arrives between the conveying frame 101 and the length trapezoidal block 115.

[0035] When the pressing plate electric cylinder 113 extends, the measuring electric cylinder 112 extends, driving the measuring frame 114 to descend. The descending of the measuring frame 114 drives the sliding column 120 and the contact head 122 to descend. When the contact head 122 contacts the tinplate sheet 210 below, the position of the sliding column 120 is detected by the thickness sensor 119 to obtain the thickness of the tinplate sheet 210, and the measurement data is fed back to the inkjet printer 301. When the contact head 122 contacts the tinplate sheet 210, the measuring frame 114 continues to descend, the extrusion spring 121 will be compressed, but the distance between the sliding column 120 and the thickness sensor 119 remains unchanged.

[0036] When the measuring frame 114 descends, the length trapezoidal block 115 will be driven to descend. After the length trapezoidal block 115 contacts the tinplate sheet 210 located between the conveying frame 101 and the length trapezoidal block 115, the tinplate sheet 210 will push the length trapezoidal block 115 to slide outward, and the long spring 116 will be compressed. When the measuring frame 114 descends to the lowest position, the position of the length trapezoidal block 115 is detected by the length sensor 117, so as to obtain the length of the tinplate sheet 210. The length of the tinplate sheet 210 is usually within a certain range. If the length is too long or too short, it cannot be measured, that is, the length trapezoidal block 115 does not move horizontally during the descent, or when it moves to the extreme position, the length sensor 117 feeds back unqualified data, and the measurement data is fed back to the inkjet printer 301.

[0037] like Figure 5 , Figure 6As shown, the plate feeding device includes a pressure slide 202 slidably mounted on a plate box 201, a baffle 209 is slidably mounted on the pressure slide 202, an outer spring 203 is arranged between the pressure slide 202 and the baffle 209, the baffle 209 is slidably mounted on the plate box 201, a lower pressure column 205 is fixedly mounted on the pressure slide 202, a pressure plate 206 is fixedly mounted on the lower pressure column 205, a pressure plate 206 is fixedly mounted on the lower pressure column 205, a pressure spring 204 is arranged between the pressure plate 206 and the plate box 201, a number of tinplate sheets 210 are placed between the pressure plate 206 and the plate box 201, and are pressed by the pressure plate 206 and the pressure spring 204, a bidirectional motor 207 is fixedly mounted on the pressure plate 206, and a friction wheel 208 is fixedly mounted on the motor shaft of the bidirectional motor 207.

[0038] like Figure 5 , Figure 6 As shown, the blocking rod 209 is provided with an inner slope surface 2091 .

[0039] A number of tinplate sheets 210 are placed between the pressing plate 206 and the plate placing box 201, and are pressed down by the downward pressing spring 204. When feeding is required, the bidirectional motor 207 rotates to drive the friction wheel 208 to rotate. The friction wheel 208 pushes the tinplate sheets 210 outward through friction. The tinplate sheets 210 contact with the baffle rod 209, and the baffle rod 209 is pressed downward through the inner slope surface 2091. The outer spring 203 is stretched, and the tinplate sheets 210 fall into the feeding slope bucket 108. The tinplate sheets 210 are intermittently pushed into the feeding slope bucket 108.

[0040] As the number of tinplate sheets 210 decreases, the press slide 202 and the press plate 206 will continue to descend, and the baffle 209 and the tinplate sheets 210 will descend synchronously, and the baffle 209 and the tinplate sheets 210 to be discharged will always maintain the same height.

[0041] like Figure 7 As shown, the printing device includes a side plate 302 fixedly mounted on the conveying frame 101, a labeling electric cylinder 303 fixedly mounted on the conveying frame 101, a labeling head 304 fixedly mounted on the top of the labeling electric cylinder 303, a sleeve 307 and a driving shaft 306 rotatably mounted on the conveying frame 101, a lower wheel 311 fixedly mounted on the driven wheel 104, an oblique transmission wheel 308 is wound around the lower wheel 311 and the driving shaft 306, a label belt 305 is mounted outside the sleeve 307, and the other end of the label belt 305 is fixed on the driving shaft 306, a push-out electric cylinder 309 fixedly mounted on the conveying frame 101, a push plate 310 fixedly mounted on the top of the push-out electric cylinder 309, and the push plate 310 is slidably mounted with the conveying frame 101.

[0042] When the length, width and height of the tinplate sheet 210 are measured, the information is recorded in the inkjet printer 301, and the push cylinder 309 is extended to drive the push plate 310 to slide in the conveyor frame 101, and the tinplate sheet 210 is pushed onto the side plate 302 by the push plate 310. When the transmission belt 106 rotates, the lower wheel 311 is driven to rotate, thereby driving the active shaft 306 to rotate through the inclined transmission wheel 308, thereby driving the label belt 305 to move, and the label There are several strip patches on the belt 305. The size information of the tinplate sheet 210 is printed on the strip patches of the label belt 305 through the inkjet printer 301. The label belt 305 moves synchronously with the transmission belt 106. When the tinplate sheet 210 is pushed onto the side plate 302, its corresponding label is just above it. The labeling electric cylinder 303 extends to press the strip patches on the label belt 305 onto the tinplate sheet 210 and stick them on the tinplate sheet 210.

[0043] The working principle of the tinplate sheet specification label sticking device disclosed in the present invention is: a plurality of tinplate sheets 210 are placed between a pressing plate 206 and a plate placing box 201, and pressed by a downward pressing spring 204. When feeding is required, a bidirectional motor 207 rotates to drive a friction wheel 208 to rotate, and the friction wheel 208 pushes the tinplate sheet 210 outward through friction. The tinplate sheet 210 contacts a baffle 209, and the baffle 209 is pressed downward through an inner slope surface 2091. The outer spring 203 is stretched, and the tinplate sheet 210 falls into the feeding slope bucket 108, and the tinplate sheet 210 is intermittently pushed into the feeding slope bucket 108. After the tinplate sheet 210 enters the feed ramp 108, it falls onto the trapezoidal block 111 and the transmission belt 106. At this time, the pressure plate electric cylinder 113 extends and descends, driving the pressure plate 123 and the outer frame 124 to descend. The pressure plate 123 descends to press the tinplate sheet 210 downward, the trapezoidal block 111 is pushed outward, and the side spring 109 is compressed. When the pressure plate 123 presses the tinplate sheet 210 between the trapezoidal block 111 and the conveyor frame 101, the trapezoidal block 111 is tensioned by the side spring 109, and the position of the sliding frame 110 is measured by the width sensor 107, thereby obtaining the width of the tinplate sheet 210, and the measurement data is fed back to the inkjet printer 301. When the pressing plate 123 descends, it will drive the outer frame 124 to descend, thereby driving the rotating gear 125 to descend. When the outer frame 124 descends, the rotating gear 125 will not drive the docking gear 103 to rotate. The rotating gear 125 rotates relative to the outer frame 124, and the bent tooth spring 105 is compressed; when the pressing plate electric cylinder 113 rises, it drives the pressing plate 123 and the outer frame 124 to rise. At this time, the rotating gear 125 rises and drives the docking gear 103 to rotate, thereby driving the driving wheel 102 to rotate, and drives the tinplate sheet 210 to advance one station through the transmission belt 106, that is, to the bottom of the contact head 122. The tinplate sheet 210 originally located below the contact head 122 arrives between the conveying frame 101 and the length trapezoidal block 115. When the pressing plate electric cylinder 113 extends, the measuring electric cylinder 112 extends, driving the measuring frame 114 to descend. The descending of the measuring frame 114 drives the sliding column 120 and the contact head 122 to descend. When the contact head 122 contacts the tinplate sheet 210 below, the position of the sliding column 120 is detected by the thickness sensor 119 to obtain the thickness of the tinplate sheet 210, and the measurement data is fed back to the inkjet printer 301. When the contact head 122 contacts the tinplate sheet 210, the measuring frame 114 continues to descend, the extrusion spring 121 will be compressed, but the distance between the sliding column 120 and the thickness sensor 119 remains unchanged.When the measuring frame 114 descends, the length trapezoidal block 115 will be driven to descend. After the length trapezoidal block 115 contacts the tinplate sheet 210 located between the conveying frame 101 and the length trapezoidal block 115, the tinplate sheet 210 will push the length trapezoidal block 115 to slide outward, and the long spring 116 will be compressed. When the measuring frame 114 descends to the lowest position, the position of the length trapezoidal block 115 is detected by the length sensor 117, so as to obtain the length of the tinplate sheet 210. The length of the tinplate sheet 210 is usually within a certain range. If the length is too long or too short, it cannot be measured, that is, the length trapezoidal block 115 does not move horizontally during the descent, or when it moves to the extreme position, the length sensor 117 feeds back unqualified data, and the measurement data is fed back to the inkjet printer 301. When the length, width and height of the tinplate sheet 210 are measured, the information is recorded in the inkjet printer 301, and the push cylinder 309 is extended to drive the push plate 310 to slide in the conveyor frame 101, and the tinplate sheet 210 is pushed onto the side plate 302 by the push plate 310. When the transmission belt 106 rotates, the lower wheel 311 is driven to rotate, thereby driving the active shaft 306 to rotate through the inclined transmission wheel 308, thereby driving the label belt 305 to move, and the label belt 305 is moved. 5, the size information of the tinplate sheet 210 is printed on the strip patch of the label belt 305 by the inkjet printer 301, the label belt 305 moves synchronously with the transmission belt 106, when the tinplate sheet 210 is pushed onto the side plate 302, its corresponding label is just above it, the labeling electric cylinder 303 extends to press the strip patch on the label belt 305 onto the tinplate sheet 210, so as to attach the specification label to the tinplate sheet 210.

[0044] Each tinplate sheet 210 is measured three times in width, thickness and length, and finally pushed onto the side plate 302 , and a specification label is attached to the tinplate sheet 210 .

[0045] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope of the present invention, which should be covered by the protection scope of the present invention.
