Description

Technical Field

[0001] This utility model relates to the technical field of aluminum can size measuring devices, specifically an aluminum can size measuring device. Background Technology

[0002] In the industrial production process of aluminum cans, after all processing steps are completed, their key dimensions need to be precisely inspected to determine whether the product meets production standards. These key dimensions include the can's height, countersunk depth, opening crimp height, and opening crimp thickness. The countersunk depth specifically refers to the height difference between the lowest point of the can's top surface and the opening crimp. To achieve efficient inspection of these key dimensions, existing technologies commonly employ automated inspection using aluminum can size measuring devices. These devices typically include a can height measuring probe for detecting the can's height, a crimp thickness measuring structure for measuring the opening crimp thickness, and a laser profile scanner for measuring the countersunk depth. However, existing can size measuring devices can only measure the height of the can body, the depth of the recess, and the thickness of the opening rolled edge. They lack the ability to measure the critical dimension of the opening rolled edge height. This results in incomplete coverage of the key dimensions of the can and makes it impossible to fully assess the dimensional compliance of the can. This may lead to substandard cans with excessive opening rolled edge height entering the market. Utility Model Content

A first connecting post 30 is provided at the bottom of the push rod mounting base 3, and a second connecting post 80 is provided at the bottom of the first guide block 8. The support seat 2 is installed on the top surface of the workbench 1, and is used to support the aluminum can 17 with its opening facing downwards; the push rod mounting seat 3 and the first slide rail 6 are both fixed to the bottom surface of the workbench 1, the first slide rail 6 is arranged in the front-back direction, the push rod 4 is movably inserted through the push rod mounting seat 3, the first slider 7 is slidably installed on the first slide rail 6, the first slider 7 is connected to the top of the guide frame 5, the first guide block 8 is installed on the guide frame 5, and one end of the push rod 4 is fixedly connected to the first guide block 8; one end of the first elastic element 9 is connected to the first connecting post 30, and the other end of the first elastic element 9 is connected to the... The second connecting column 80 is described; the first connecting frame 10 is fixedly connected to the left side of the first guide block 8, the first guide roller 11 is rotatably mounted on the left side of the first connecting frame 10, and the pressing bolt 12 passes through the top of the first connecting frame 10; the tank height measuring component 13, the edge height measuring component 14, the edge thickness measuring component 15, and the countersunk depth measuring component 16 are all disposed on the workbench 1, the second guide roller 131 and the third guide roller 141 are respectively disposed on the first guide block 8, the driving block 151 is respectively disposed on the pressing bolt 12, and the second guide block 160 is respectively disposed on the first guide roller 11; The can height measuring component 13 is used to measure the height of the can 17 when the second guide roller 131 and the first guide block 8 are in a non-contact state; the edge curling height measuring component 14 is used to measure the height of the edge curling of the can 17 opening when the third guide roller 141 and the first guide block 8 are in a non-contact state; the edge curling thickness measuring component 15 is used to measure the thickness of the edge curling of the can 17 opening when the drive block 151 and the pressing bolt 12 are in a non-contact state; and the countersunk depth measuring component 16 is used to measure the countersunk depth of the can 17 when the second guide block 160 and the first guide roller 11 are in a non-contact state.

[0017] This solution provides a device for measuring the size of an aluminum can, such as... Figure 1-2 , Figure 4-5 and Figure 9As shown, in this embodiment, the first elastic element 9 is a spring. When it is necessary to measure the height, submerged depth, opening edge height, and opening edge thickness of the can, the operator first manually pushes the push rod 4 backward. Through the transmission of the push rod 4, the first guide block 8 moves backward, thereby driving the first connecting frame 10 to move backward, which in turn drives the first guide roller 11 and the pressing bolt 12 to move backward. This causes the second guide roller 131 of the can height measuring component 13 to contact the first guide block 8, the third guide roller 141 of the edge height measuring component 14 to contact the first guide block 8, the drive block 151 of the edge thickness measuring component 15 to contact the pressing bolt 12, and the second guide block 160 of the submerged depth measuring component 16 to contact the first guide roller 11. At this time, the can height measuring component 13, the edge height measuring component 14, the edge thickness measuring component 15, and the submerged depth measuring component 16 are all in a stopped measuring state, and the first elastic element 9 is in a compressed state. Subsequently, the staff placed the can 17 to be tested precisely onto the support 2 with the opening facing down. Finally, the staff releases the push rod 4, which moves forward under the reset action of the first elastic element 9, thereby driving the first guide block 8 to move forward, which in turn drives the first connecting frame 10 to move forward, which in turn drives the first guide roller 11 and the pressing bolt 12 to move forward. This causes the second guide roller 131 of the can height measuring component 13 to move away from the first guide block 8, the third guide roller 141 of the edge height measuring component 14 to move away from the first guide block 8, the drive block 151 of the edge thickness measuring component 15 to move away from the pressing bolt 12, and the second guide block 160 of the countersunk depth measuring component 16 to move away from the first guide roller 11. At this time, the can height measuring component 13, the edge height measuring component 14, the edge thickness measuring component 15, and the countersunk depth measuring component 16 simultaneously start the measurement function, completing the comprehensive measurement of the height, countersunk depth, opening edge height, and opening edge thickness of the can 17 in one go.

[0018] To further explain, the cooperation between the guide frame 5, the first slide rail 6 and the first slider 7 enables the first guide block 8, the first guide roller 11 and the pressing bolt 12 to move more stably.

[0019] This solution, by setting up a can height measurement component 13, a rolled edge height measurement component 14, a rolled edge thickness measurement component 15, and a recessed depth measurement component 16, can achieve full coverage measurement of four key dimensions of the beverage can 17: height, recessed depth, opening rolled edge height, and opening rolled edge thickness. It can comprehensively evaluate the dimensional compliance of the beverage can 17 from multiple dimensions. In particular, it effectively controls the lack of "opening rolled edge height" index detection in existing equipment, thereby effectively preventing unqualified beverage cans with excessive opening rolled edge height from entering the market and providing reliable technical support for quality control at the production end.

[0020] Preferably, the tank height measuring assembly 13 further includes a first guide seat 132, a lifting plate 133, a roller mounting bracket 134, a second slide rail 135, two second sliders 136, a tank height display 137, and a tank height measuring sensing pin 138. The tank height display 137 includes a first elastic end 1370. The first guide seat 132 is installed on the top surface of the workbench 1. The second slide rail 135 is installed on the first guide seat 132. The second slide rail 135 is arranged in the vertical direction. The two second sliders 136 can be slidably installed on the second slide rail 135. The lifting plate 133 is connected to the two second sliders 136. The roller mounting bracket 134 is fixedly connected to the bottom of the lifting plate 133. The roller mounting bracket 134 is movably inserted through the table surface of the workbench 1. The second guide roller 131 is rotatably installed on the roller mounting bracket 134. The tank height display 137 is installed on the top of the first guide seat 132. The first elastic end 1370 of the tank height display 137 is connected to the top of the lifting plate 133. The tank height measuring sensing pin 138 is detachably installed on the lifting plate 133. The first guide block 8 is inclined on the side near the second guide roller 131 and the third guide roller 141.

[0021] In this embodiment, as Figure 2-3As shown, the first elastic end 1370 is a spring. The can size measuring device also includes a controller 18, which is electrically connected to the can height display 137 and the can height measuring sensing pin 138. Since the first guide block 8 is inclined near the side of the second guide roller 131 and the third guide roller 141, when measuring the can height of the can 17, the operator first pushes the push rod 4 backward. The push rod 4 drives the first guide block 8 to move backward, so that the inclined surface of the first guide block 8 abuts against the second guide roller 131, thereby generating an upward force on the roller mounting bracket 134, which in turn drives the lifting plate 133 to rise, thereby driving the can height measuring sensing pin 138 to rise. At this time, the first elastic end 1370 is in a compressed state. Then, the can 17 to be tested is accurately placed on the support base 2 with the opening facing downward. After the can 17 to be tested is placed, the operator releases the push rod 4. The push rod 4 moves forward under the reset action of the first elastic element 9, thereby driving the first guide block 8 to move forward. At this time, the first guide block 8 separates from the second guide roller 131. The lifting plate 133 moves downward under the reset action of the first elastic end 1370 of the can height display 137, causing the can height measuring sensor pin 138 to descend and touch the bottom of the can 17 to be tested. The can height measuring sensor pin 138 transmits the detected can height analog signal of the can 17 to the controller 18. After data processing, the can height data is obtained and transmitted to the can height display 137 for display.

[0022] Preferably, the lifting plate 133 has a plurality of mounting holes 1330 along its length, and the plurality of mounting holes 1330 are evenly distributed at equal intervals. The tank height measuring sensing pin 138 can be selectively assembled with each of the mounting holes 1330. In this embodiment, as shown... Figure 3 As shown, since the can height measuring sensor pin 138 can be selectively assembled with each of the mounting holes 1330, the operator can select the corresponding mounting hole 1330 according to the height specification of the can 17 and assemble the can height measuring sensor pin 138 into the mounting hole 1330, thereby ensuring that the can height measuring sensor pin 138 can accurately touch the bottom of the can 17 during subsequent testing.

[0023] Preferably, the hem height measuring assembly 14 further includes a second guide seat 142, a third slide rail 143, a third slider 144, a second connecting frame 145, a second elastic element 146, a lifting frame 147, a hem height display table 148, and a hem height measuring probe 149, wherein the hem height display table 148 includes a second elastic end 1480. The second guide seat 142 is mounted on the bottom surface of the workbench 1. The third slide rail 143 is mounted on the second guide seat 142 and is arranged vertically. The third slider 144 is slidably mounted on the third slide rail 143. The second connecting frame 145 is fixedly connected to the third slider 144. One end of the second elastic member 146 is connected to the top of the second guide seat 142, and the other end of the second elastic member 146 is connected to the left side of the second connecting frame 145. The lifting frame... The third guide roller 141 is rotatably mounted on the lifting frame 147, the top of the lifting frame 147 passes through the table surface of the workbench 1 and extends in the vertical direction; the edge curling height measuring probe 149 is mounted on the top of the lifting frame 147 and is located on one side of the support seat 2; the edge curling height display 148 is mounted on the top surface of the workbench 1, and the second elastic end 1480 of the edge curling height display 148 is connected to the right side of the second connecting frame 145.

[0024] In this embodiment, as Figure 4 As shown. The second elastic element 146 and the second elastic end 1480 are both springs. The controller 18 is also electrically connected to the edge height display 148 and the edge height measuring probe 149, respectively. Since the first guide block 8 is inclined near the side of the second guide roller 131 and the third guide roller 141, when detecting the edge height of the can 17, the operator first pushes the push rod 4 backward. Through the transmission of the push rod 4, the first guide block 8 moves backward, so that the inclined surface of the first guide block 8 abuts against the third guide roller 141, thereby generating an upward force on the lifting frame 147, thereby driving the lifting frame 147 to rise, and thus driving the edge height measuring probe 149 to rise. At this time, the second elastic element 146 and the second elastic end 1480 are both in a compressed state. Then, the can 17 to be tested is accurately placed on the support 2 with the opening facing down. After the can 17 to be tested is placed, the operator releases the push rod 4. The push rod 4 moves forward under the reset action of the first elastic element 9, thereby driving the first guide block 8 to move forward. At this time, the first guide block 8 separates from the third guide roller 141. The lifting frame 147 moves downward under the reset action of the second elastic element 146 and the second elastic end 1480, causing the edge curling height measuring probe 149 to descend and contact the top of the edge curling of the can 17 to be tested. The edge curling height measuring probe 149 transmits the detected edge curling height analog signal of the can 17 to the controller 18. After data processing, the edge curling height data is obtained and transmitted to the edge curling height display table 148 for display.

[0025] Preferably, the edge thickness measuring component 15 further includes a limiting block 152, a fourth slide rail 153, a fourth slider 154, a third elastic element 155, a connecting seat 156, a shift fork 157, an edge thickness display table 158, and an edge thickness measuring probe 159, wherein the edge thickness display table 158 includes a third elastic end 1580. The fourth slide rail 153 is mounted on the bottom surface of the worktable 1. The fourth slide rail 153 is arranged in the front-to-back direction. The limiting block 152 is mounted on the rear end of the fourth slide rail 153. The fourth slider 154 is slidably mounted on the fourth slide rail 153. The driving block 151 is fixedly connected to the fourth slider 154. One end of the third elastic member 155 is connected to the limiting block 152, and the other end of the third elastic member 155 is connected to the driving block 151. The connecting seat... 156 is fixed to the right side of the drive block 151. The top of the connecting seat 156 passes through the table surface of the workbench 1. The shift fork 157 is installed in the center of the top of the connecting seat 156. The edge thickness display 158 is installed on the top surface of the workbench 1. The edge thickness measuring probe 159 is connected to the third elastic end 1580 of the edge thickness display 158. The edge thickness measuring probe 159 is located at the opening of the shift fork 157 and is located on one side of the bearing seat 2. When the fork 157 moves in the front-back direction, the fork 157 will come into contact with or separate from the end of the edge thickness measuring probe 159.

[0026] In this embodiment, as Figure 5-8As shown, both the third elastic element 155 and the third elastic end 1580 are springs. The controller 18 is also electrically connected to the edge thickness display 158 and the edge thickness measuring probe 159, respectively. When detecting the edge thickness of the can 17, the operator first pushes the push rod 4 backward. The push rod 4 drives the first guide block 8 to move backward, thereby driving the first connecting frame 10 to move backward, which in turn drives the pressing bolt 12 to move backward, thereby pushing the drive block 151 to move backward, which in turn drives the connecting seat 156 to move backward, which in turn drives the fork 157 to move backward. During the backward movement of the fork 157, it will abut against the end of the edge thickness measuring probe 159 and drive the edge thickness measuring probe 159 to move backward. At this time, both the third elastic element 155 and the third elastic end 1580 are in a compressed state. Then, the can 17 to be tested is accurately placed on the support seat 2 with the opening facing downward. After the aluminum can 17 to be tested is placed, the staff releases the push rod 4. The push rod 4 moves forward under the reset action of the first elastic element 9, thereby driving the first guide block 8 to move forward, thereby driving the first connecting frame 10 to move forward, thereby driving the pressing bolt 12 to move forward, so that the pressing bolt 12 separates from the driving block 151. At this time, the driving block 151 moves forward under the reset action of the third elastic element 155, thereby driving the connecting seat 156 to move forward, thereby driving the shift fork 157 to move forward, so that the shift fork 157 separates from the end of the edge thickness measuring probe 159. Subsequently, the edge thickness measuring probe 159 moves forward under the reset action of the third elastic end 1580 of the edge thickness display table 158 and touches the edge of the opening of the can 17 to be tested. The edge thickness measuring probe 159 transmits the detected edge thickness analog signal of the opening of the can 17 to the controller 18. After data processing, the edge thickness data is obtained and transmitted to the edge thickness display table 158 for display.

[0027] To further explain, the limiting block 152 is configured to limit the drive block 151, preventing the drive block 151 from moving excessively beyond the length range of the fourth slide rail 153.

[0028] Preferably, the edge thickness measuring assembly 15 further includes two guide wheels 150, which are rotatably mounted on the left and right sides of the top of the connecting seat 156, respectively. In this embodiment, as... Figure 7As shown, when the connecting seat 156 moves forward under the reset action of the third elastic member 155, the two guide wheels 150 can form a stable abutment against the opening rolled edge of the can 17 to be tested, thereby ensuring that the rolled edge thickness measuring probe 159 makes precise contact with the opening rolled edge of the can 17 to be tested.

[0029] Preferably, the countersunk depth measuring assembly 16 further includes a probe mounting bracket 161, a third guide seat 162, a fifth slide rail 163, a fifth slider 164, a first connecting block 165, a second connecting block 166, a fourth elastic element 167, a countersunk depth display table 168, and a countersunk depth measuring probe 169, wherein the countersunk depth display table 168 includes a fourth elastic end 1680. The third guide seat 162 is mounted on the bottom surface of the workbench 1. The fifth slide rail 163 is mounted on the third guide seat 162 and is arranged vertically. The fifth slider 164 is slidably mounted on the fifth slide rail 163. The first connecting block 165 is fixedly connected to the fifth slide rail 163, and the second connecting block 166 is fixedly connected to the first connecting block 165. One end of the fourth elastic member 167 is connected to the bottom of the second connecting block 166, and the other end of the fourth elastic member 167 is connected to the third guide seat 162. The bottom of 2; the probe mounting bracket 161 is fixedly connected to the bottom right side of the second connecting block 166, the countersunk depth measuring probe 169 is mounted on the probe mounting bracket 161, and the second guide pressure block 160 is mounted on the top right side of the second connecting block 166; the top of the countersunk depth measuring probe 169 passes through the table surface of the workbench 1 and is located on one side of the support seat 2; the countersunk depth display 168 is mounted on the top of the workbench 1, and the fourth elastic end 1680 of the countersunk depth display 168 is connected to the top left side of the second connecting block 166; The second guide block 160 is inclined on the side near the first guide roller 11.

[0030] In this embodiment, as Figure 9As shown, both the fourth elastic element 167 and the fourth elastic end 1680 are springs. The controller 18 is also electrically connected to the countersinking depth display 168 and the countersinking depth measuring probe 169. Since the second guide block 160 is inclined near the side of the first guide roller 11, when detecting the countersinking depth of the can 17, the operator first pushes the push rod 4 backward. The push rod 4 drives the first guide block 8 backward, which in turn drives the first connecting frame 10 backward, which in turn drives the first guide roller 11 backward. This causes the inclined surface of the second guide block 160 to contact the first guide roller 11, generating a downward force on the probe mounting frame 161. This causes the countersinking depth measuring probe 169 to descend, which in turn causes the second connecting block 166 to descend. At this time, the fourth elastic element 167 and the fourth elastic end 1680 are in a stretched state. Subsequently, the can 17 to be tested is accurately placed on the support 2 with its opening facing downward. After the aluminum can 17 to be tested is placed, the operator releases the push rod 4. The push rod 4 moves forward under the reset action of the first elastic element 9, thereby driving the first guide block 8 to move forward, thereby driving the first connecting frame 10 to move forward, thereby driving the first guide roller 11 to move forward, so that the first guide roller 11 separates from the second guide block 160. At this time, the second connecting block 166 moves upward under the reset action of the fourth elastic element 167 and the fourth elastic end 1680, thereby driving the probe mounting frame 161 to move upward, thereby driving the countersunk depth measuring probe 169 to move upward and touch the lowest point of the top surface of the opening of the aluminum can 17 to be tested and the opening rolled edge. The countersunk depth measuring probe 169 transmits the detected countersunk depth analog signal of the aluminum can 17 to the controller 18. After data processing, the countersunk depth data is obtained and transmitted to the countersunk depth display table 168 for display.
