Description

Technical Field

[0001] This utility model belongs to the field of canning equipment, and in particular relates to a capping device for medicinal paste cans. Background Technology

[0002] Existing canning devices for traditional Chinese medicine pastes, such as the vacuum capping machine for sealing canned goods (application number 202321082740.5), include a base with a turntable on the base. The turntable has two lower molds, which alternately pass under the upper mold to place the can into the cavity of the lower mold and place the cap onto the screw thread of the can. The lower mold can be rotated slightly to ensure the accurate positioning of the cap on the can. When the lower mold is below the upper mold, a cylinder is used to press the can tightly to prevent the can from slipping during the capping process. The upper mold descends, a vacuum is drawn, and the cap is tightened under vacuum to complete the capping. Then the upper mold rises, and the capped can can be removed.

[0003] In actual production, it was found that the existing capping device still has some shortcomings, mainly as follows:

[0004] First, the depth of the mold cavity is not matched with the height of the can, resulting in a large depth. When workers place the can into the mold cavity, they hold the upper part of the can, making it difficult to place the can smoothly into the mold cavity. In many cases, the can is released after most of the can has entered the mold cavity, and the can eventually fall into the mold cavity, causing significant vibration. Some cans are filled with very thin paste, which may overflow, requiring the can to be cleaned, increasing production costs. In addition, the paste in the mold cavity also needs to be cleaned in time after reaching a certain amount, reducing production efficiency.

[0005] Secondly, because the depth of the lower mold cavity matches the height of the can, it is difficult for workers to find a good stress point when putting in or taking out the can. In addition, there is a lifting motion when picking up and putting out the can, which makes the can picking and putting out slow, further reducing production efficiency. In fact, because the can is difficult to hold, it may slip out of the hand and break. Utility Model Content

[0006] The purpose of this invention is to provide a capping device for medicinal paste cans. This invention has the advantages of high production efficiency and low production cost.

[0007] The technical solution of this utility model is as follows: a can capping device for medicinal paste, including a workbench, an electrically driven turntable above the workbench, a guide channel above the turntable, an inlet of the guide channel opening, an electrically driven feeding wheel on one side of the outlet of the guide channel, a plurality of evenly distributed feeding grooves on the outer circumference of the feeding wheel, and a capping mechanism on the rear side of the guide channel.

[0008] The capping mechanism includes an upper mold, a mold cavity that mates with the can on the bottom surface of the upper mold, a vacuum device that connects to the mold cavity on the side wall of the upper mold, a lifting mechanism that connects to the worktable on the top of the upper mold, a pressure plate on the bottom of the mold cavity, and the lifting mechanism that connects to the pressure plate through a rotating mechanism.

[0009] In the aforementioned canning device for medicinal pastes, an arc-shaped inner guide rail and an arc-shaped outer guide rail are provided above the turntable. A guide channel is formed between the inner and outer guide rails. The feeding end of the inner guide rail is bent radially inward, and the feeding end of the outer guide rail is bent radially outward. Both the inner and outer guide rails are fixed to the worktable by connecting rods.

[0010] In the aforementioned canned herbal paste capping device, the workbench is equipped with a first motor whose output end is fixed to the turntable and a second motor whose output end is fixed to the feeding wheel. A plane bearing is provided between the turntable and the workbench, and an annular groove is provided on the outer circumferential surface of the feeding wheel. The outer guide rail passes through the annular groove.

[0011] In the aforementioned canning device for medicinal pastes, a sealing ring is provided on the bottom surface of the upper mold.

[0012] In the aforementioned canning device for medicinal pastes, the lifting mechanism includes a support fixed to the workbench. A first cylinder is provided at the top of the support. A box is provided at the telescopic end of the first cylinder. Multiple bolts are provided inside the box. The bolts pass through the bottom plate of the box and connect to the upper mold. A spiral first compression spring is sleeved on the bolt. The first compression spring is located between the box and the upper mold.

[0013] In the aforementioned canning device for medicinal pastes, the rotating mechanism includes a through hole at the top of the upper mold, a rotor inside the through hole, the upper end of the rotor extending into the housing and connected to a gear, a rack slidably connected to the housing on one side of the gear, a second cylinder with its telescopic end connected to the rack inside the housing, a plug screw connected to the rotor on the pressure plate, and a guide post inserted into the rotor on the pressure plate.

[0014] In the aforementioned medicated paste can capping device, there are at least three guide pillars, and a spiral second compression spring is sleeved on the guide pillars. The second compression spring is located between the rotor and the pressure plate.

[0015] In the aforementioned canning device for medicinal pastes, an annular friction plate is provided on the bottom surface of the pressing plate.

[0016] In the aforementioned canning device for medicinal pastes, a guide bar is provided on the rear side of the canning mechanism. The rear end of the guide bar extends to the outside of the workbench. A storage platform is provided below the rear end of the guide bar. The surface of the storage platform is close to the turntable and is at the same height as the turntable.

[0017] In the aforementioned canning device for medicinal pastes, a wiping block that contacts the turntable is provided on the rear side of the guide strip. The wiping block is made of water-absorbing material and is fixed to the worktable.

[0018] Compared with existing technologies, this invention eliminates the lower mold, using only the upper mold to complete the vacuuming and tightening of the lid on the can. The can can be placed directly on the turntable. When workers pick up and place the cans, there are no obstacles around, allowing them to hold the can in the middle with good leverage. This makes can handling quick and stable, improving production efficiency, preventing the contents of the can from overflowing, keeping the turntable and the can's exterior clean, reducing subsequent cleaning processes, and lowering production costs. Therefore, this invention has the advantages of high production efficiency and low production cost. Attached Figure Description

An annular groove 16 is provided on the outer circumference of the feeding wheel 4, and the outer guide rail 12 passes through the annular groove 16.

[0030] A capping mechanism is provided on the rear side of the guide channel 3. The capping mechanism includes an upper mold 6, a sealing ring 17 on the bottom surface of the upper mold 6, and a mold cavity 9 on the bottom surface of the upper mold 6 that mates with the can 7. A guide bevel is preferably provided on the opening of the mold cavity 9. The mold cavity 9 is located inside the sealing ring 17. A vacuum pump is provided on the side wall of the upper mold 6, connecting to the mold cavity 9. The vacuum pump is used. A lifting mechanism connected to the worktable 1 is provided on the top of the upper mold 6. A pressure plate 10 is provided at the bottom of the mold cavity 9. The lifting mechanism is connected to the pressure plate 10 via a rotating mechanism. An annular friction plate 29 is provided on the bottom surface of the pressure plate 10. The friction plate 29 can be made of rubber. A guide hole 34 is provided on the outer side wall of the upper mold 6. A piston 35 is provided inside the guide hole 34. An elastic wear-resistant layer, such as a rubber block, is preferably provided on the front end face of the piston 35. A third cylinder 36 with a telescopic end fixed to the piston 35 is provided on the outer side of the upper mold 6.

[0031] The lifting mechanism includes a bracket 18 fixed to the worktable 1. A first cylinder 19 is provided on the top of the bracket 18. The first cylinder 19 is a dual-axis cylinder. A housing 20 is provided at the telescopic end of the first cylinder 19. Multiple bolts 21 are provided inside the housing 20. The bolts 21 have threads only at the front end and are smooth shafts at the rear. The bolts 21 are slidably connected to the housing 20. The bolts 21 pass through the bottom plate of the housing 20 and connect to the upper mold 6. A spiral first compression spring 22 is sleeved on the bolts 21. The first compression spring 22 is located between the housing 20 and the upper mold 6.

[0032] The rotating mechanism includes a through hole at the top of the upper mold 6, within which a rotor 23 is housed. The upper end of the rotor 23 extends into the housing 20 and is connected to a gear 24. The rotor 23 is bearing-connected to the housing 20. A sealing ring can be installed on the outer wall of the rotor 23 to improve the sealing between the rotor 23 and the upper mold 6. A rack 25 is provided on one side of the gear 24 and is slidably connected to the housing 20. A second cylinder 26 with its telescopic end connected to the rack 25 is provided inside the housing 20. A locking screw 27 is provided on the pressure plate 10 to connect to the rotor 23. The locking screw 27 is slidably connected to the pressure plate 10. The pressure plate 10 has at least three guide posts 37, each inserted into the rotor 23. The guide posts 37 are slidably connected to the rotor 23 and maintain a clearance fit to ensure proper venting. A helical second compression spring 28 is fitted on the guide posts 37 and is located between the rotor 23 and the pressure plate 10.

[0033] The capping mechanism has a guide strip 30 located above the turntable 2 on its rear side. The guide strip 30 is fixed to the worktable 1, and its rear end extends to the outside of the worktable 1. A storage platform 31 is located below the rear end of the guide strip 30, with its surface close to and at the same height as the turntable 2. A wiping block 32, made of absorbent material such as a sponge, is located on the rear side of the guide strip 30 and contacts the turntable 2. The wiping block 32 is fixed to the worktable 1 via an adapter. The wiping block 32 is constantly wet and requires replenishment and periodic replacement. A slot can be provided on the adapter to hold the wiping block 32, preventing it from moving with the turntable 2. The wiping block 32 is used to keep the turntable 2 clean, ensuring a good vacuuming effect.

[0034] Preferably, both the first motor 14 and the second motor 15 are stepper motors with drivers, and guide bars can also be provided on the outer side of the guide bar 30 so that the can passes between the guide bar 30 and the guide bar.

[0035] Instructions for use: Place the cans 7 with their caps pre-screwed onto the front side of the guide channel 3. The first motor 14 drives the turntable 2 to rotate, and the turntable 2 carries the cans 7 into the guide channel 3 and onto the feeding roller 4. Under the action of the inner and outer guide rails, multiple cans 7 are arranged in a row in the guide channel 3. The feeding roller 4 blocks the cans 7 in front from moving forward, while the turntable 2 continues to drive the subsequent cans 7 forward, so that multiple cans 7 in the guide channel 3 are placed close together in sequence.

[0036] Repeat steps 1 through 10 as one loop:

[0037] Step 1: The second motor 15 starts, and the feeding wheel 4 rotates at a certain angle. The rotation angle depends on the number of feeding troughs 5. For example, if there are 12 troughs, the rotation angle is 30°.

[0038] Step 2: The rotation of the feeding wheel 4 allows one can to pass through, and the next can to enter the corresponding feeding trough 5. The first motor 14 drives the turntable 2 to rotate at a certain angle, so that the passing can reaches the bottom of the upper mold 6.

[0039] Step 3: The first cylinder 19 extends, causing the upper mold 6 to descend. First, the friction plate 29 contacts the lid on the can, and the first compression spring 22 is compressed. Then, the sealing ring 17 contacts the turntable 2, and the second compression spring 28 is compressed.

[0040] Step 4: Activate the vacuum device 8 to expel the air from the mold cavity 9.

[0041] Step 5: The third cylinder 36 extends, causing the piston 35 to press the can tightly against the cylinder.

[0042] Step 6: The second cylinder 26 extends, causing the rack 25 to drive the gear 24 to rotate. The gear 24 drives the cover to rotate through the rotor 23, guide post 37, pressure plate 10, and friction plate, and the cover is tightened.

[0043] Step 7: The third cylinder 36 retracts, and the piston 35 separates from the can.

[0044] Step 8: Vacuum device 8 is turned off, and the pressure inside the mold cavity 9 returns to normal.

[0045] Step 9: The first cylinder 19 retracts, and the upper mold 6 rises to restore its original height.

[0046] Step 10: The second cylinder 26 retracts.

[0047] The canned goods with the lids pressed are guided by the guide bar 30 and placed into the storage platform 31 for temporary storage. The workers then transfer the canned goods on the storage platform 31 to another process.

[0048] Alternatively, a PLC controller, such as the FX1N, can be added. The vacuum pump, the first motor, and the second motor are all connected to the PLC controller, and the first cylinder, the second cylinder, and the third cylinder are all connected to the PLC controller via solenoid valves. This allows steps 1 to 10 above to be performed automatically in a loop.

[0049] In the description of the embodiments, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the embodiments 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, and therefore should not be construed as a limitation.
