Description

Technical Field

[0001] This utility model relates to the field of aerosol can processing technology, and in particular to an aerosol can cap pressing device. Background Technology

[0002] Aerosol can cap pressing equipment is a specialized device used to press caps onto aerosol cans. It applies pressure to the cap on the aerosol can, causing it to snap into place, thus completing the pressing process. In existing technologies, aerosol cans are prone to displacement during cap pressing due to shaking, resulting in inaccurate alignment between the cap and the aerosol can. This prevents the cap from tightly fastening onto the aerosol can, thereby reducing the quality of the pressing process. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes an aerosol can cap pressing device that can prevent the aerosol can from shaking during the cap pressing process, thereby improving the cap pressing quality.

[0004] The aerosol can cap pressing equipment according to an embodiment of the present invention includes a frame, a conveying device, a cap feeding device, a pressing device, and a pressing device.

[0005] The machine frame is equipped with a feeding station and a pressing station; a conveying device is mounted on the machine frame to convey multiple aerosol cans so that the multiple aerosol cans can be moved sequentially to the feeding station and the pressing station; a bottle cap feeding device is mounted on the machine frame to make the bottle caps fall onto the aerosol cans at the feeding station; a pressing device is mounted on the machine frame to press the aerosol cans at the pressing station onto the conveying device; a pressing device is mounted on the machine frame to press the bottle caps on the aerosol cans at the pressing station so that the bottle caps are fastened onto the aerosol cans.

[0006] It has at least the following beneficial effects:

[0007] A conveyor system transports multiple aerosol cans, sequentially moving them to the unloading station and the pressing station. When aerosol cans reach the unloading station, a cap-unloading device places the caps onto the cans. The conveyor system then continues to move the cans and their caps to the pressing station. Once at the pressing station, a clamping device presses the cans firmly against the conveyor to prevent movement. After clamping, a pressing device presses the caps onto the cans at the pressing station, securing them to the cans. After pressing, the clamping device releases the cans, and the conveyor system continues transporting cans awaiting pressing and those already pressed. The clamping device in this aerosol can cap pressing equipment can press the aerosol can tightly during the cap pressing process, preventing the aerosol can from shifting position due to shaking, ensuring accurate alignment between the cap and the aerosol can, and thus improving the cap pressing quality.

[0008] According to an embodiment of the aerosol can cap pressing equipment of the present utility model, the pressing device includes a support, a first elastic element and two pressure rollers. The support is slidably connected to the frame so that the support can move closer to or away from the conveying device. The upper and lower ends of the two pressure rollers are rotatably connected to the support. The outer walls of the opposite sides of the two pressure rollers are used to abut against the aerosol can. The two ends of the first elastic element are respectively connected to the support and the frame. The first elastic element is used to push the support closer to the conveying device so that the two pressure rollers can press the aerosol can at the pressing station onto the conveying device.

[0009] According to the aerosol can cap pressing device of this utility model embodiment, a rubber sleeve is provided on the outer wall of each of the two pressure rollers, and the two pressure rollers abut against the aerosol can through the rubber sleeve.

[0010] According to the aerosol can cap pressing equipment of this utility model embodiment, the distance between the two pressing rollers can be adjusted.

[0011] According to the aerosol can cap pressing equipment of this utility model embodiment, the conveying device includes a first conveying mechanism, an intermittently arranged conveying mechanism and a second conveying mechanism arranged sequentially from back to front. The first conveying mechanism and the second conveying mechanism are both used to convey multiple aerosol cans from back to front. The intermittently arranged conveying mechanism is used to arrange and convey multiple aerosol cans at intervals, so that multiple aerosol cans move sequentially to the unloading station and the pressing station.

[0012] According to an embodiment of the aerosol can cap pressing equipment of the present utility model, the spaced conveying mechanism includes a motor, a turntable, a support plate, and an arc-shaped barrier. The support plate and the arc-shaped barrier are both mounted on the frame. The turntable is rotatably connected to the support plate. The turntable, the arc-shaped barrier, and the support plate together form an arc-shaped track for the aerosol can to move. The edge of the turntable is provided with multiple positioning grooves, which are used to accommodate the aerosol can and the cap. The motor is mounted on the frame and is used to drive the turntable to rotate, so that the turntable moves the aerosol can along the arc-shaped track and moves the aerosol can sequentially to the unloading station and the pressing station.

[0013] According to the aerosol can cap pressing equipment of this utility model embodiment, the spaced conveying mechanism further includes an arc baffle, the arc baffle is connected to the upper end of the arc enclosure, and the arc baffle is used to keep against the cap to prevent the cap from coming out of the positioning groove.

[0014] According to the aerosol can cap pressing equipment of this utility model embodiment, the arc baffle is an arc spring sheet, and the gap between the arc spring sheet and the outer wall of the turntable gradually decreases along the rotation direction of the turntable, so that the arc spring sheet can press the cap tightly onto the inner wall of the positioning groove.

[0015] According to the aerosol can cap pressing equipment of this utility model embodiment, the pressing device includes a cylinder and a pressing block. The cylinder body is disposed on the frame, and the pressing block is disposed at the pressing station and connected to the piston rod of the cylinder. The cylinder can drive the pressing block to descend so that the pressing block presses the cap on the aerosol can at the pressing station.

[0016] According to the aerosol can cap pressing device of this utility model embodiment, the pressing device further includes a second elastic element and a pressure plate. The upper end of the second elastic element is connected to the pressing block, and the lower end of the second elastic element is connected to the pressure plate. The pressing block presses the cap through the pressure plate.

[0035] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model 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 utility model.

[0036] In the description of this utility model, the use of "first" and "second" is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features or the order of the technical features.

[0037] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0038] refer to Figures 3 to 5 This utility model discloses an aerosol can cap pressing equipment, including a frame 500, a conveying device 100, a cap feeding device 200, a pressing device 300, and a pressing device 400.

[0039] The frame 500 is equipped with a feeding station and a pressing station; a conveying device 100 is mounted on the frame 500 and is used to convey multiple aerosol cans so that they can be moved sequentially to the feeding station and the pressing station; a cap feeding device 200 is mounted on the frame 500 and is used to place caps onto the aerosol cans at the feeding station; a pressing device 300 is mounted on the frame 500 and is used to press the aerosol cans at the pressing station onto the conveying device 100; a pressing device 400 is mounted on the frame 500 and is used to press the caps on the aerosol cans at the pressing station so that the caps are fastened onto the aerosol cans. (Reference) Figure 1 and Figure 2 It should be explained that, in this embodiment of the utility model, the bottle cap is provided with an annular flange, and the outer wall of the aerosol can is provided with an annular ridge. When the bottle cap is pressed down, the annular flange on the bottle cap and the annular ridge on the aerosol can are engaged, and the bottle cap can be fastened onto the aerosol can to complete the pressing of the bottle cap.

[0040] Understandably, the conveyor 100 transports multiple aerosol cans, allowing them to move sequentially to the unloading station and the pressing station. When the aerosol cans reach the unloading station, the cap unloading device 200 allows the caps to land on the aerosol cans at the unloading station. The conveyor 100 then continues to move the aerosol cans and their caps to the pressing station. Once at the pressing station, the pressing device 300 presses the aerosol cans firmly against the conveyor 100 to prevent them from shaking. After pressing, the pressing device 400 presses the caps onto the aerosol cans at the pressing station, securing them to the aerosol cans and completing the pressing process. After pressing, the pressing device 300 releases the aerosol cans, and the conveyor 100 continues to transport aerosol cans awaiting pressing and those that have completed pressing. The clamping device 300 in the aerosol can cap pressing equipment can press the aerosol can tightly during the cap pressing process, preventing the aerosol can from shifting position due to shaking, ensuring accurate alignment between the cap and the aerosol can, and thus improving the cap pressing quality.

[0041] refer to Figure 4 The bottle cap feeding device 200 includes a circular vibratory feeder (not shown in the figure), a linear vibratory feeder 210, and a blocking device (not shown in the figure). Both the circular and linear vibratory feeders 210 are mounted on the frame 500. The blocking device is located at the discharge end of the linear vibratory feeder 210 and is used to open or block the discharge end of the linear vibratory feeder 210. The discharge end of the circular vibratory feeder is connected to the feed end of the linear vibratory feeder 210, and the discharge end of the linear vibratory feeder 210 is positioned above the feeding station. It is understood that the circular vibratory feeder contains a large number of bottle caps. After the circular vibratory feeder is started, it can adjust the posture of the bottle caps, causing the bottle caps to face downwards and move sequentially into the linear vibratory feeder 210. After the linear vibratory feeder 210 is started, it conveys the bottle caps, allowing them to move towards the feeding station. When the aerosol can moves to the unloading station, the shield opens the discharge end of the vibratory feeder 210, causing a bottle cap to fall out and land on the aerosol can. Then, the shield blocks the discharge end of the vibratory feeder 210 to prevent it from falling out. The bottle cap unloading device 200 is a common device for feeding bottle caps. The circular vibratory feeder, the vibratory feeder 210, and the shield are also common components, and will not be described further here.

[0042] refer to Figure 6 and Figure 7The pressing device 300 includes a support 310, a first elastic element 320, and two pressure rollers 330. The support 310 is slidably connected to the frame 500 so that it can move closer to or further away from the conveying device 100. The upper and lower ends of the two pressure rollers 330 are rotatably connected to the support 310, and the outer walls of opposite sides of the two pressure rollers 330 are used to abut against the aerosol cans. The two ends of the first elastic element 320 are respectively connected to the support 310 and the frame 500. The first elastic element 320 is used to push the support 310 closer to the conveying device 100 so that the two pressure rollers 330 can press the aerosol cans at the pressing station onto the conveying device 100. It can be understood that after the cap feeding device 200 places the caps onto the aerosol cans at the feeding station, the conveying device 100 continues to drive the aerosol cans and the caps on them toward the pressing station. During the movement of the aerosol can, it first abuts against one of the pressure rollers 330 located upstream. As the aerosol can continues to move, it pushes the pressure roller 330, causing the support 310 and the two pressure rollers 330 to move away from the conveying device 100, and the first elastic element 320 begins to compress. As the aerosol can continues to move, it reaches the pressing station, and the conveying device 100 stops conveying the aerosol can, leaving the aerosol can and its cap at the pressing station. At this time, the outer walls of the two pressure rollers 330 on opposite sides abut against the aerosol can, and under the action of the first elastic element 320, the support 310 and the two pressure rollers 330 tend to move towards the conveying device 100, thus pressing the aerosol can firmly onto the conveying device 100.

[0043] After the bottle cap is pressed into place, the conveying device 100 drives the aerosol can to move. During this movement, the aerosol can compresses one of the downstream pressure rollers 330, causing the support 310 and both pressure rollers 330 to move away from the conveying device 100. As the aerosol can continues to move, it disengages from between the two pressure rollers 330 and leaves the pressing station. In this embodiment, the first elastic element 320 can be a compression spring. As one embodiment of this utility model, the aerosol can cap pressing equipment further includes two slide rods 350, two first elastic elements 320, and two sliding holes on the frame 500. One end of each slide rod 350 is connected to a support 310, and the other end of each slide rod 350 passes through the two sliding holes. The two first elastic elements 320 are respectively sleeved on the two slide rods 350, with one end of each first elastic element 320 abutting against the support 310 and the other end abutting against the frame 500. It is understood that the support 310 can move closer to or further away from the turntable 140 in the conveying device 100 under the guidance of the two slide rods 350; this will not be further elaborated here. In this embodiment of the utility model, rubber sleeves are fitted on the outer walls of both pressure rollers 330, and both pressure rollers 330 abut against the aerosol can through these rubber sleeves. It is understood that both pressure rollers 330 are abutted against the aerosol can by rubber sleeves to avoid direct contact between the pressure rollers 330 and the aerosol can, thus preventing damage to the aerosol can. As one embodiment of this utility model, the rubber sleeves can be common silicone sleeves or rubber sleeves.

[0044] refer to Figure 7 The distance between the two pressure rollers 330 is adjustable. It can be understood that by adjusting the distance between the two pressure rollers 330, they can compress aerosol cans of different diameters. When compressing aerosol cans with larger diameters, the worker can increase the distance between the two pressure rollers 330; when compressing aerosol cans with smaller diameters, the worker can decrease the distance between the two pressure rollers 330. Further details are omitted here. Specifically, the compression device 300 also includes two supports 340, with the two pressure rollers 330 rotatably connected to the two supports 340 respectively. The support 310 has an oblong hole 360, and both supports 340 are slidably connected to the oblong hole 360 ​​on the support 310 via a bolt and nut (not shown in the figure) structure. The bolt, nut, and oblong hole 360 ​​sliding structure is a common adjustable structure and will not be further described here.

[0045] refer to Figure 3 and Figure 6The conveying device 100 includes a first conveying mechanism 110, an intermittently arranged conveying mechanism 130, and a second conveying mechanism 120 arranged sequentially from back to front. Both the first and second conveying mechanisms 110 and 120 are used to convey multiple aerosol cans from back to front. The intermittently arranged conveying mechanism 130 is used to arrange and convey the multiple aerosol cans at intervals, so that the multiple aerosol cans move sequentially to the unloading station and the pressing station. It is understood that the intermittently arranged conveying mechanism 130 is located between the first and second conveying mechanisms 110 and 120. The output end of the first conveying mechanism 110 corresponds to the input end of the intermittently arranged conveying mechanism 130, and the input end of the intermittently arranged conveying mechanism 130 corresponds to the input end of the second conveying mechanism 120. The first conveying mechanism 110 conveys the multiple aerosol cans from back to front, allowing the multiple aerosol cans to move into the intermittently arranged conveying mechanism 130. The spaced-out conveyor mechanism 130 separates multiple aerosol cans, allowing them to move sequentially to the unloading and pressing stations. Under the conveying action of the spaced-out conveyor mechanism 130, the pressed aerosol cans are then sequentially moved to the second conveyor mechanism 120. Finally, the second conveyor mechanism 120 moves the pressed aerosol cans to subsequent processing equipment. The coordinated arrangement of the first conveyor mechanism 110, the spaced-out conveyor mechanism 130, and the second conveyor mechanism 120 is a common setup in the production of bottle-shaped products. Both the first conveyor mechanism 110 and the second conveyor mechanism 120 are common tracked conveyor mechanisms, which will not be further elaborated here. It should be noted that the first conveyor mechanism 110 and the second conveyor mechanism 120 can be a single, integrated linear conveyor mechanism.

[0046] refer to Figures 3 to 8The spaced-out conveying mechanism 130 includes a motor (not shown in the figure), a turntable 140, a support plate 180, and an arc-shaped barrier 150. Both the support plate 180 and the arc-shaped barrier 150 are mounted on the frame 500. The turntable 140 is rotatably connected to the support plate 180. The turntable 140, the arc-shaped barrier 150, and the support plate 180 together form an arc-shaped track for moving the aerosol cans. The edge of the turntable 140 has multiple positioning grooves 141, each used to accommodate an aerosol can and a bottle cap. The motor is mounted on the frame 500 and drives the turntable 140 to rotate, causing the turntable 140 to move the aerosol cans along the arc-shaped track and sequentially move them to the unloading station and the pressing station. In this invention, the multiple positioning grooves 141 are circumferentially distributed around the central axis of the turntable 140. Understandably, the edge of the turntable 140, the arc-shaped enclosure 150, and the support plate 180 enclose an arc-shaped track for the movement of aerosol cans. The rear end of the arc-shaped track is connected to the front end of the first conveying mechanism 110, so that multiple aerosol cans conveyed by the first conveying mechanism 110 can be moved sequentially into the arc-shaped track. The front end of the arc-shaped track is connected to the rear end of the second conveying mechanism 120, so that multiple aerosol cans with caps pressed into the arc-shaped track can be moved sequentially onto the second conveying mechanism 120.

[0047] A motor drives the turntable 140 to rotate, causing multiple positioning slots 141 on the edge of the turntable 140 to move sequentially to the front end of the first conveying mechanism 110. Under the forward conveying action of the first conveying mechanism 110, multiple aerosol cans on the first conveying mechanism 110 can move sequentially into the multiple positioning slots 141 on the edge of the turntable 140. Under the rotation of the turntable 140, the aerosol cans in the multiple positioning slots 141 can move sequentially to the unloading station and the pressing station. When an aerosol can moves to the unloading station, the turntable 140 stops rotating, and at this time, there are aerosol cans at both the unloading station and the pressing station. Then, the cap unloading device 200 and the pressing device 400 are activated simultaneously, so that the caps in the cap unloading device 200 can fall onto the aerosol cans at the unloading station, and the pressing device 400 presses the caps on the aerosol cans at the pressing station. Once the aerosol can is moved to the pressing station by the turntable 140, the two pressure rollers 330 press the aerosol can firmly against the inner wall of the positioning groove 141 to prevent the aerosol can from shaking during the pressing process. It should be explained that after the cap feeding device 200 places the cap onto the aerosol can at the feeding station, the cap is positioned within the positioning groove 141. During the rotation of the turntable 140, the inner wall of the positioning groove 141 moves the cap, and the aerosol can also move the cap, allowing the cap to move synchronously with the aerosol can. The inner wall of the positioning groove 141 positions the cap, ensuring precise positioning between the cap and the aerosol can, thus allowing the cap to be tightly fastened onto the aerosol can.

[0048] It should be explained that the support plate 180 supports the aerosol can, allowing it to move on the support plate 180. Both the first conveying mechanism 110 and the second conveying mechanism 120 are common tracked conveying mechanisms, and the upper surfaces of the tracks in both mechanisms are flush with the upper surface of the support plate 180. This allows the aerosol cans on the track of the first conveying mechanism 110 to move onto the support plate 180, and also allows the aerosol cans on the support plate 180 to move onto the track of the second conveying mechanism 120 under the drive of the turntable 140. Further details will not be elaborated here. (Reference) Figure 9 The spaced-alternate conveying mechanism 130 also includes an arc-shaped guide plate 170. The aerosol cans on the first conveying mechanism 110 abut against the rear end of the arc-shaped guide plate 170, allowing them to move into the positioning groove 141 on the turntable 140. The aerosol cans in the positioning groove 141 of the turntable 140 abut against the front end of the arc-shaped guide plate 170, allowing them to move onto the second conveying mechanism 120. The arc-shaped guide plate 170 is a common structure in spaced-alternate conveying mechanisms 130 and will not be described further here.

[0049] refer to Figures 7 to 9 The spaced-out conveying mechanism 130 also includes an arc-shaped baffle 160, which is connected to the upper end of the arc-shaped barrier 150. The arc-shaped baffle 160 is used to keep the bottle cap abutting against it, thus preventing the bottle cap from detaching from the positioning groove 141. It is understood that after the bottle cap falls onto the aerosol can and is positioned in the positioning groove 141, the bottle cap can remain abutting against the arc-shaped baffle 160 as the turntable 140 rotates. The arc-shaped baffle 160 limits the movement of the bottle cap, preventing it from detaching from the positioning groove 141 or the aerosol can, ensuring the smooth operation of the pressing process.

[0050] refer to Figure 9 The arc-shaped baffle 160 is an arc-shaped spring sheet. The gap between the arc-shaped spring sheet and the outer wall of the turntable 140 gradually decreases along the rotation direction of the turntable 140, so that the arc-shaped spring sheet can press the bottle cap tightly against the inner wall of the positioning groove 141. It can be understood that as the bottle cap moves with the turntable 140, because the gap between the arc-shaped spring sheet and the outer wall of the turntable 140 gradually decreases, the bottle cap begins to squeeze the arc-shaped spring sheet, causing the arc-shaped spring sheet to undergo elastic deformation. At this time, the arc-shaped spring sheet will apply a force to the bottle cap close to the turntable 140. Therefore, when the turntable 140 stops moving and the bottle cap remains at the pressing position, the arc-shaped spring sheet can press the bottle cap tightly against the inner wall of the positioning groove 141, preventing the bottle cap from shaking and ensuring precise positioning of the bottle cap and aerosol can, thereby improving the pressing quality of the bottle cap. After the bottle cap is pressed into place, the turntable 140 continues to rotate, allowing the bottle cap to come out from the gap between the turntable 140 and the arc-shaped spring piece.

[0051] refer to Figure 7 The pressing device 400 includes a cylinder 410 and a pressing block 420. The cylinder body of the cylinder 410 is mounted on the frame 500. The pressing block 420 is located at the pressing station and connected to the piston rod of the cylinder 410. The cylinder 410 can drive the pressing block 420 to descend, so that the pressing block 420 presses down on the bottle cap of the aerosol can at the pressing station. It can be understood that after the bottle cap and aerosol can move to the pressing station, the cylinder 410 drives the pressing block 420 to descend, allowing the pressing block 420 to press down on the bottle cap of the aerosol can, thereby allowing the bottle cap to be fastened onto the aerosol can, thus completing the pressing of the bottle cap. After the pressing of the bottle cap is completed, the cylinder 410 drives the pressing block 420 to rise, and the turntable 140 continues to move the bottle cap and aerosol can.

[0052] refer to Figure 10 In another embodiment of this utility model, the pressing device 400 further includes a second elastic element 430 and a pressure plate 440. The upper end of the second elastic element 430 is connected to the pressure block 420, and the lower end of the second elastic element 430 is connected to the pressure plate 440. The pressure block 420 presses the bottle cap through the pressure plate 440. The piston rod of the cylinder 410 drives the pressure block 420 to move downward, and the pressure block 420 drives the connected second elastic element 430 and the pressure plate 440 to descend synchronously. It can be understood that the cylinder 410 drives the pressure block 420 to descend, so that the pressure block 420 drives the second elastic element 430 and the pressure plate 440 to descend. When the pressure plate 440 contacts the bottle cap, the second elastic element 430 begins to compress and deform to buffer the impact force of the downward movement of the cylinder 410, so that the pressure of the pressure plate 440 on the bottle cap gradually increases. During this process, the second elastic element 430 converts the rigid driving force of the cylinder 410 into flexible pressing, avoiding instantaneous impact that could cause bottle cap deformation or can damage. Simultaneously, the second elastic buffer ensures that the pressure plate 440 smoothly adheres to the bottle cap surface, achieving uniform pressing and improving the pressing quality of the bottle cap. In this embodiment of the invention, the second elastic element 430 can be a compression spring.

[0053] refer to Figure 10The pressure block 420 has guide holes parallel to the vertical direction, and the pressure plate 440 has a guide rod 450, which passes through the guide holes. The second elastic element 430 is sleeved on the guide rod 450. It can be understood that the guide rod 450 can slide vertically within the guide holes, thus guiding the vertical movement of the pressure plate 440 and ensuring its smooth vertical movement. The second elastic element 430, sleeved on the guide rod 450, also guides the compression and extension of the second elastic element 430, allowing it to undergo smooth elastic deformation. In this embodiment of the utility model, the pressing device 400 further includes a plurality of second elastic elements 430, the pressing block 420 is provided with a plurality of circumferentially distributed guide holes, the pressing plate 440 is provided with a plurality of circumferentially distributed guide rods 450, the plurality of guide rods 450 are respectively inserted into the plurality of guide holes, and the plurality of second elastic elements 430 are respectively sleeved on the plurality of guide rods 450, which will not be further described here.

[0054] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0055] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
