Description

Technical Field

[0001] This application relates to the field of packaging machinery technology, and in particular to a capping machine. Background Technology

[0002] Aluminum drums are widely used in the chemical industry for liquid packaging due to their lightweight and corrosion resistance. The sealing performance of aluminum drums depends on the quality of the interference fit between the lid and the body, which usually requires a press to apply vertical pressure to the lid for assembly.

[0003] In related technologies, a manual press is typically used to assemble the bucket lid. The manual press includes a base, a machine head, a rocker arm, a gear, a rack, a sliding block, and a pressure plate at the bottom of the sliding block. A worktable is set on the base, and the machine head is vertically mounted on the base. Both the gear and the rack are installed inside the machine head. The gear is sleeved on the rocker arm, and the rack is fixed to the side wall of the sliding block. In use, the aluminum bucket is first placed on the worktable, and then the bucket lid is placed at the mouth of the aluminum bucket. Then, the rocker arm is rotated to convert the rotational motion of the gear into the linear motion of the sliding block, which causes the sliding block to drive the pressure plate to press down on the bucket lid, thereby embedding the bucket lid into the bucket body.

[0004] In practical use, it was found that operators need to visually position the aluminum drums on the workbench to ensure they are aligned with the axis of the pressure plate. When sealing several aluminum drums sequentially, frequent manual operation can lead to fatigue. Repeated placement of the drums can cause positioning errors, and adjustments to the drums' positions can easily result in misalignment, ultimately leading to a poor seal between the lid and the drum. Summary of the Invention

[0005] To improve the positioning accuracy of aluminum drums, this application provides a capping machine that has the effect of improving the positioning accuracy of aluminum drums.

[0006] The capping machine provided in this application adopts the following technical solution:

[0007] A capping machine includes a base, on which a worktable for placing an aluminum drum is slidably disposed, and on the worktable a clamping mechanism for clamping the aluminum drum. A machine head is disposed on the base, and a pressure plate is disposed at one end of the machine head near the base. A driving mechanism for driving the pressure plate to press down is disposed on the machine head, and a laser emitter is disposed on the machine head. The light projected by the laser emitter is aligned with the edge of the aluminum drum.

[0008] By adopting the above technical solution, the aluminum drum is first placed on the workbench. The light projected by the laser emitter aligns the edge of the aluminum drum with the light. Then, the clamping mechanism is activated to firmly clamp the aluminum drum, reducing the displacement of the filter cartridge. Finally, the drive mechanism is activated to move the pressure plate downward, completing the sealing operation of the aluminum drum. This application achieves high-precision alignment between the aluminum drum and the pressure plate by means of the laser emitter and the clamping mechanism, effectively reducing the sealing failure caused by positioning deviation and improving the positioning accuracy of the aluminum drum.

[0009] Optionally, the clamping mechanism includes a clamping block, a trapezoidal groove is provided on the worktable, the clamping block is slidably connected to the trapezoidal groove, a bidirectional lead screw is rotatably connected to the inner wall of the trapezoidal groove, the clamping block is threadedly connected to the bidirectional lead screw, and one end of the bidirectional lead screw passes through the worktable and is provided with a knob.

[0010] By adopting the above technical solution, when the knob is turned, the bidirectional lead screw drives the two clamping blocks to move closer and further apart synchronously until they abut against the outer wall of the aluminum bucket, thus completing the clamping of the aluminum bucket. The sliding fit between the trapezoidal groove and the clamping blocks effectively reduces the shaking of the clamping blocks during movement, further improving the stability of the clamping.

[0011] Optionally, the drive mechanism includes a lifting rod mounted on the machine head, a rack fixed on the lifting rod, a gear meshing with the rack, and a rocker arm. One end of the lifting rod extends out of the machine head and is connected to the pressure plate. The rack extends vertically along the lifting rod. The gear is coaxially fixed to one end of the rocker arm. The other end of the rocker arm extends out of the machine head and is connected to a rotating handle.

[0012] By adopting the above technical solution, when the operator rotates the handle, the rocker arm drives the gear to rotate synchronously, which in turn drives the rack to move linearly, converting the circular motion of the rotating handle into the linear motion of the lifting rod, making the operation simple and convenient.

[0013] Optionally, a fixing rod is provided at one end of the lifting rod near the pressure plate, and a bracket is slidably provided on the fixing rod, and the laser emitter is fixedly mounted on the bracket.

[0014] By adopting the above technical solution, when it is necessary to adjust the position of the laser emitter, the laser beam projection position can be changed by pushing the card holder to slide along the fixed rod, so that the aluminum barrel is aligned with the pressure plate before sealing, which effectively improves the positioning accuracy of the aluminum barrel and is conducive to adapting to sealing scenarios of aluminum barrels with different diameters.

[0015] Optionally, the clamping block is provided with an arc-shaped plate that fits against the outer peripheral wall of the aluminum barrel.

[0016] By adopting the above technical solution, when the clamping block approaches the aluminum barrel, the arc-shaped plate matches the arc shape of the outer peripheral wall of the aluminum barrel, which can increase the contact area with the aluminum barrel, effectively disperse the clamping force, reduce the deformation and other damage to the aluminum barrel during the clamping process, and protect the appearance quality of the aluminum barrel.

[0017] Optionally, a pressure sensor is provided on the pressure plate to detect the pressure of the pressure plate.

[0018] By adopting the above technical solution, when the lifting rod moves the pressure plate closer to and contacts the aluminum barrel, pressure is generated between the pressure plate and the aluminum barrel. By observing the pressure value data fed back by the pressure sensor, the operator can easily control the pressure.

[0019] Optionally, the base is provided with a column, one end of which is fixedly mounted to the machine head, and one end of the worktable is provided with a sleeve, which is slidably connected to the column. The sleeve is provided with a locking element for locking the sleeve onto the column.

[0020] By adopting the above technical solution, the sleeve can be moved up and down along the vertical direction of the column by pushing the worktable, thereby adjusting the height of the worktable. This can adapt to the sealing scenarios of aluminum barrels of different heights and improve the adaptability of the structure.

[0021] Optionally, the base is also provided with a counterweight.

[0022] By adopting the above technical solution, when the components above the base are covered, the components above will generate a large downward pressure. The counterweight can effectively increase the weight of the base, reduce the occurrence of tilting or shaking of the overall equipment, and improve the overall stability of the equipment.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. First, place the aluminum drum on the workbench. The edge of the aluminum drum is aligned with the light projected by the laser emitter. Then, the clamping mechanism is activated to firmly clamp the aluminum drum, reducing the displacement of the filter cartridge. Finally, the drive mechanism is activated to move the pressure plate downward, completing the sealing operation of the aluminum drum. This application uses the laser emitter and clamping mechanism to achieve high-precision alignment between the aluminum drum and the pressure plate, effectively reducing the sealing failure caused by positioning deviation and improving the positioning accuracy of the aluminum drum.

[0025] 2. When the knob is turned, the bidirectional lead screw drives the two clamping blocks to move closer and further apart synchronously until they come into contact with the outer wall of the aluminum bucket, thus completing the clamping of the aluminum bucket. The sliding fit between the trapezoidal groove and the clamping blocks effectively reduces the shaking of the clamping blocks during movement, further improving the stability of the clamping.

[0026] 3. When the position of the laser emitter needs to be adjusted, the laser beam projection position can be changed by pushing the card holder along the fixed rod, so that the laser emitter is aligned with the pressure plate before the aluminum barrel is sealed. This effectively improves the positioning accuracy of the aluminum barrel and is beneficial for adapting to sealing scenarios of aluminum barrels with different diameters.

[0031] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0032] This application discloses a capping machine, referring to... Figure 1 The system includes a base 1, on which a worktable 2 for placing an aluminum bucket is slidably mounted. A clamping mechanism 3 for holding and fixing the aluminum bucket is mounted on the worktable 2. A machine head 4 is mounted on the top of the base 1, and a pressure plate 5 is mounted on the side of the machine head 4 near the base 1. A drive mechanism 6 is installed inside the machine head 4 to drive the pressure plate 5 to move up and down. The worktable 2 is located between the base 1 and the pressure plate 5. The machine head 4 also has a laser emitter 7. When the aluminum bucket is placed on the worktable 2, the light emitted by the laser emitter 7 is aligned with the edge of the aluminum bucket. First, the position of the aluminum bucket is adjusted so that the edge of the aluminum bucket is aligned with the light projected by the laser emitter 7. Then, the aluminum bucket is clamped by the clamping mechanism 3. Finally, the drive mechanism 6 drives the pressure plate 5 to press down, causing the edge of the bucket lid to be pressed into the groove of the aluminum bucket, thus sealing the aluminum bucket. This application improves the consistency between the axis of the aluminum bucket and the pressure plate 5 by mechanically positioning the aluminum bucket, effectively improving the positioning accuracy of the aluminum bucket.

[0033] Reference Figure 1A vertical column 14 is mounted on the base 1. One end of the column 14 is fixedly connected to the top of the base 1 via a flange, and the other end is fixedly connected to one side of the machine head 4. A sleeve 15 is integrally formed on one side of the worktable 2, and the sleeve 15 is fitted onto the column 14. Two ear plates are arranged opposite each other on the sleeve 15, and both ear plates have bolt holes. A locking element 16 passes through the sleeve 15. In this embodiment, the locking element 16 is a bolt, which passes through the two bolt holes and is threadedly connected to the sleeve 15, so that the sleeve 15 drives the worktable 2 to be fixed to the column 14. When it is necessary to adjust the height of the worktable 2, the locking element 16 is loosened, so that the sleeve 15 rises and falls on the column 14 until it rises and falls to the appropriate position. Then the locking element 16 is tightened to fix the sleeve 15 on the column 14, which is beneficial for sealing aluminum barrels of different heights.

[0034] Reference Figure 1 and Figure 2 The clamping mechanism 3 includes two clamping blocks 32. A trapezoidal groove 31 is formed along the length of the worktable 2, and both clamping blocks 32 are slidably connected within the trapezoidal groove 31. A bidirectional lead screw 8 is rotatably connected to the inner wall of the trapezoidal groove 31. Both clamping blocks 32 are sleeved on the bidirectional lead screw 8 and threadedly connected to it. One end of the bidirectional lead screw 8 passes through the side wall of the worktable 2 and is fixedly connected to a knob 9. By turning the knob 9, the two clamping blocks 32 are moved closer or further apart, thereby causing them to abut against the outer wall of the aluminum bucket, reducing bucket displacement. Simultaneously, by adjusting the distance between the two clamping blocks 32, different sizes of aluminum buckets can be accommodated, improving structural adaptability.

[0035] Reference Figure 2 An arc-shaped plate 12 is fixedly connected to one side of each of the two clamping blocks 32 that are close to each other. The arc-shaped plate 12 fits against the edge of the aluminum barrel, and a rubber pad is fixed on the arc-shaped plate 12. When the clamping block 32 moves the arc-shaped plate 12 to clamp the aluminum barrel, the rubber pad fits against the outer wall of the aluminum barrel, reducing wear on the outer wall of the aluminum barrel caused by hard collision. At the same time, the curvature of the arc-shaped plate 12 matches the edge of the aluminum barrel, which is conducive to achieving precise positioning of the aluminum barrel and improving the positioning accuracy of the aluminum barrel.

[0036] Reference Figure 1 and Figure 3 The drive mechanism 6 includes a lifting rod 61, which vertically passes through the machine head 4 and is connected to the pressure plate 5. An elastic element 18 is fixedly connected to the end of the lifting rod 61 away from the pressure plate 5. In this embodiment, the elastic element 18 is a return spring. A support rod 19 is fixedly connected to the machine head 4, with one end of the support rod 19 fixedly connected to the end of the return spring away from the lifting rod 61. When the lifting rod 61 rises and falls within the machine head 4, the spring compresses or stretches along with the lifting rod 61, which helps improve the stability of the lifting rod 61's rise and fall.

[0037] Reference Figure 1, Figure 2 and Figure 3 A connecting hole is provided through one side wall of the machine head 4, and a bearing is fixedly connected to the inner wall of the connecting hole. One end of the rocker arm 64 passes through the machine head 4 and is connected to the bearing, realizing the rotational connection between the rocker arm 64 and the machine head 4. The drive mechanism 6 also includes a lifting rod 61, a rack 62, a rocker arm 64, and a gear 63. The rack 62 is fixedly connected to the side wall of the lifting rod 61, and the gear 63 is fixedly sleeved on the rocker arm 64 located inside the machine head 4 along the circumference of the rocker arm 64. The gear 63 and the rack 62 mesh with each other. A rotating handle 20 is also fixedly connected to the end of the rocker arm 64 away from the gear 63. During operation, rotating the rotating handle 20 causes it to rotate circumferentially. At this time, rotating the handle 20 drives the gear 63 to rotate through the rocker arm 64. The gear 63 drives the rack 62 to move in the vertical direction, thereby causing the pressure plate 5 to press down and press the bucket lid tightly onto the aluminum bucket.

[0038] Reference Figure 1 A fixed rod 10 is fixedly connected to one end of the lifting rod 61 near the pressure plate 5. The fixed rod 10 is perpendicular to the trapezoidal groove 31. Both ends of the fixed rod 10 are slidably connected to the card seats 11. A laser emitter 7 is fixedly connected to the side of the two card seats 11 that are close to each other. The distance between the two laser emitters 7 is the diameter of the aluminum barrel. A display is also fixed on the machine head 4 to display the distance between the two laser emitters 7.

[0039] Reference Figure 1 A pressure sensor 13 is also fixedly connected to the pressure plate 5. The pressure sensor 13 is located between the pressure plate 5 and the lifting rod 61, which facilitates the detection of the pressure value of the lifting rod 61 and reduces the possibility of damage to the aluminum bucket and lid due to excessive pressure.

[0040] Reference Figure 1 The base 1 is also fixedly connected to a counterweight 17, which can lower the center of gravity of the overall equipment and reduce the tilting and shaking of the upper parts during operation.

[0041] The implementation principle of the capping machine disclosed in this application is as follows: First, the aluminum barrel is placed on the workbench 2 so that the two sides of the aluminum barrel are aligned with the light projected by the laser emitter 7. Then, the knob 9 is rotated, and the bidirectional lead screw 8 drives the arc plate 12 to clamp the other two sides of the aluminum barrel, realizing the alignment operation between the aluminum barrel and the pressure plate 5. Then, the handle 20 is rotated, which drives the gear 63 to mesh with the rack 62, converting the rotational motion into the linear motion of the rack 62, so that the lifting rod 61 drives the pressure plate 5 to press down. The pressure sensor 13 on the pressure plate 5 monitors the pressure value in real time. When the pressure reaches the appropriate value, the aluminum barrel is capped. Then, the handle 20 is rotated in the opposite direction to reset the pressure plate 5. This application effectively improves the positioning accuracy of the aluminum barrel on the workbench 2, thereby improving the sealing performance of the aluminum barrel.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
