Technical Field

[0001] The present application relates to the field of mechanical equipment, and more specifically to an automatic cover lowering mechanism for a nozzle. Background Art

[0002] Nozzle cover, such as Figure 1 As shown, a soft straw 2 is provided at the lower end. Since the spray head cover 1 is provided with the soft straw 2, the soft straw 2 is easily deformed and difficult to align with the bottle mouth, resulting in that conventional covering methods such as hanging cover, robot cover, and poke cover cannot realize the spray head cover 1 being covered on the bottle, and workers are required to operate manually, which greatly affects the processing efficiency and increases the cost.

[0003] In view of this, the inventor has designed a lower cover mechanism which can cover the spray head onto the bottle through mechanical automation. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the utility model is to provide an automatic cover-lowering mechanism for a spray head, which has the advantage that a spray head cover with a soft straw can be accurately and efficiently installed on a bottle through automated mechanical operation, thereby effectively improving work efficiency and reducing costs.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an automatic cap-lowering mechanism for nozzles, comprising a cap-feeding guide rail for transporting nozzle caps and a conveyor belt for transporting bottles, the nozzle caps having a soft straw at the lower end, a frame being arranged at the discharge end of the cap-feeding guide rail, the frame being provided with a clamping device for clamping the nozzle caps and mounting the nozzle caps on the bottles below at one end away from the cap-feeding guide rail, a pipe-straightening device for straightening the soft straws and moving in cooperation with the clamping device being arranged on the frame and below the clamping device, a positioning device for positioning the bottles on the conveyor belt being arranged on the frame and below the pipe-straightening device, the conveyor belt being located below the frame, and infrared sensors for identifying nozzle caps and bottles being arranged on both the cap-feeding guide rail and the conveyor belt.

[0006] By adopting the above technical solution, when the nozzle cover with the soft straw needs to be installed on the bottle, the nozzle cover is transported by the cover feeding guide rail. When the nozzle cover moves to the infrared sensor recognition position on the cover feeding guide rail, the cover feeding guide rail stops moving, and when the bottle on the conveyor belt moves to the recognition position of the corresponding infrared sensor, the conveyor belt stops moving; then the positioning device positions and tightens the recognized bottle on the conveyor belt, and then the clamping device clamps the recognized nozzle cover on the cover feeding guide rail and clamps the nozzle cover to the bottle. The nozzle cap is directly above the bottle opening, at which point the soft straw is located above the bottle; then the straw-straightening device fits the soft straw at the nozzle cover and moves vertically, so that the straw-straightening device straightens the soft straw vertically downward, at which point the lower end of the soft straw is facing the bottle opening; then the clamping device drives the nozzle cover and the soft straw to move downward, and the soft straw first enters the bottle; the straw-straightening device loosens the soft straw; the clamping device drives the nozzle cover to cover the bottle opening; finally, the clamping device loosens the nozzle cover and the straw-straightening device moves up to reset, and the positioning device releases the bottle.

[0007] In summary, the above-mentioned clamping device, the tube straightening device and the positioning device can effectively position the bottle, then clamp the spray head cover, and then straighten the soft straw, and finally accurately install the spray head cover and the soft straw on the bottle opening, thereby achieving automated mechanical operation, and the spray head cover with the soft straw can be accurately and efficiently installed on the bottle, effectively increasing work efficiency and reducing costs.

[0008] The utility model is further configured as follows: the clamping device includes a lower cover cylinder arranged on the frame and with a piston rod pointing vertically downward, a cover removing cylinder arranged on the piston rod of the lower cover cylinder and with the piston rod horizontally facing the cover feeding guide rail, a first pneumatic clamp arranged on the piston rod of the cover removing cylinder and with a clamping arm facing the cover feeding guide rail, and a clamping head arranged on the clamping arm corresponding to the first pneumatic clamping head and used for clamping the nozzle cover.

[0009] By adopting the above technical solution, when it is necessary to clamp the nozzle cover, the cover removing cylinder drives the first pneumatic clamp to move toward the nozzle cover identified on the cover feeding guide rail through the piston rod. After moving to the specified position, the first pneumatic clamp drives the clamp through the clamp arm to tighten the nozzle cover, and then the piston rod of the first pneumatic clamp is reset. At this time, the nozzle cover is located directly above the bottle opening; when the tube straightening device straightens the soft straw, the lower cover cylinder drives the cover removing cylinder and the first pneumatic clamp to move downward through the piston rod until the soft straw and the nozzle cover enter the bottle opening one after another, and finally the clamp releases the nozzle cover, and the piston rod of the lower cover cylinder is reset.

[0010] The utility model is further configured as follows: a plurality of supporting slide bars are vertically arranged on the frame, and a first balancing frame which is slidably matched with the supporting slide bars is arranged on the cap removing cylinder.

[0011] By adopting the above technical solution, the provision of the first balancing frame helps to stabilize the cap removing cylinder during its movement.

[0012] The utility model is further configured as follows: the tube-pulling device includes a first tube-pulling cylinder arranged on the frame and with a piston rod vertically downward, a second tube-pulling cylinder arranged on the piston rod of the first tube-pulling cylinder and with a piston rod vertically downward, a second pneumatic clamp arranged on the piston rod of the second tube-pulling cylinder and with a clamping arm facing the cover feeding guide rail, and a clamping finger arranged on the clamping arm corresponding to the second pneumatic clamp and used to fit the soft straw.

[0013] By adopting the above technical scheme, when the clamping device clamps the nozzle cover and is located directly above the bottle, the clamping fingers are located at the upper end of the soft straw, and the second pneumatic clamp drives the clamping fingers through the clamping arm to fit the soft straw. Then the first pipe-pushing cylinder drives the second pipe-pushing cylinder and the second pneumatic clamp to move downward through the piston rod, and the soft straw fitted with the two clamping fingers is gradually straightened under the downward action of the two clamping fingers; then the clamping device drives the nozzle cover to move downward, and at this time the second pipe-pushing cylinder drives the second pneumatic clamp to move downward through the piston rod. During the downward movement of the soft straw, it always remains in a vertical state under the action of the clamping fingers, so that it can accurately enter the bottle opening. When the second pipe-pushing cylinder moves to the lowest end, the clamping fingers release the soft straw. During the resetting process of the clamping device, the first pipe-pushing cylinder and the second pipe-pushing cylinder drive the second pneumatic clamp to reset.

[0014] The utility model is further configured as follows: one end of the two clamping fingers facing the cover feeding guide rail is provided with vertical downward arc grooves, and when the two clamping fingers are combined, the two arc grooves are combined into a hole for straightening the soft straw.

[0015] By adopting the above technical solution, the setting of the arc groove helps the soft straw to always be located in the hole when the two clamping fingers are closed, thereby ensuring that the soft straw is always facing the bottle opening under the action of the two clamping fingers.

[0016] The utility model is further configured as follows: a plurality of supporting slide bars are vertically arranged on the frame, and a second balancing frame which is slidably matched with the supporting slide bars is arranged on the second pipe-pulling cylinder and the second pneumatic clamp.

[0019] By adopting the above technical solution, when the bottle on the conveyor belt is identified, the conveyor belt stops operating. At this time, the bottle is located between the two positioning cylinders. Then the two positioning cylinders drive the two positioning parts to move toward each other through the piston rod, and the bottle is positioned under the action of the arc grooves of the two positioning parts.

[0020] In summary, the utility model has the following advantages:.

[0021] 1.

[0022] 2. When it is necessary to clamp the nozzle cover, the cover-removing cylinder drives the first pneumatic clamp to move toward the nozzle cover identified on the cover-feeding guide rail through the piston rod.

[0029] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0031] like Figure 2 , 3 As shown, the clamping device includes a lower cover cylinder 6 installed on the frame 4 with a piston rod vertically downward, a cover removal cylinder 7 installed on the piston rod of the lower cover cylinder 6 with the piston rod horizontally facing the cover delivery guide rail 3, a first pneumatic clamp 8 installed on the piston rod of the cover removal cylinder 7 with a clamping arm facing the cover delivery guide rail 3, and a clamp 9 installed on the clamping arm corresponding to the first pneumatic clamp 8 and used to clamp the nozzle cover 1.

[0032] When it is necessary to clamp the nozzle cover 1, the cap removing cylinder 7 drives the first pneumatic clamp 8 to move toward the nozzle cover 1 identified on the cap feeding guide rail 3 through the piston rod. After moving to the specified position, the first pneumatic clamp 8 drives the clamp 9 to tighten the nozzle cover 1 through the clamp arm, and then the piston rod of the first pneumatic clamp 8 is reset. At this time, the nozzle cover 1 is located directly above the bottle opening; when the tube straightening device straightens the soft straw 2, the lower cover cylinder 6 drives the cap removing cylinder 7 and the first pneumatic clamp 8 to move downward through the piston rod until the soft straw 2 and the nozzle cover 1 enter the bottle opening one after another, and finally the clamp 9 releases the nozzle cover 1, and the piston rod of the lower cover cylinder 6 is reset.

[0033] Furthermore, a plurality of support slide bars 10 are vertically mounted on the frame 4, and a first balancing frame 11 is mounted on the cap removing cylinder 7 to slide with the support slide bars 10, which helps to stabilize the cap removing cylinder 7 during movement.

[0034] like Figure 2 , 4 As shown, the tube-pulling device includes a first tube-pulling cylinder 12 installed on the frame 4 with a piston rod pointing vertically downward, a second tube-pulling cylinder 13 installed on the piston rod of the first tube-pulling cylinder 12 with a piston rod pointing vertically downward, a second pneumatic clamp 14 installed on the piston rod of the second tube-pulling cylinder 13 with a clamping arm facing the cover feeding guide rail 3, and a clamping finger 15 installed on the clamping arm corresponding to the second pneumatic clamp 14 and used for fitting the soft straw 2.

[0035] When the clamping device clamps the spray head cover 1 and is located just above the bottle, the clamping finger 15 is located at the upper end of the soft straw 2, and the second pneumatic clamping gripper 14 drives the clamping finger 15 through the clamping arm to fit the soft straw 2, and then the first pipe-pushing cylinder 12 drives the second pipe-pushing cylinder 13 and the second pneumatic clamping gripper 14 to move downward through the piston rod, and the soft straw 2 fitted with the two clamping fingers 15 is gradually straightened under the downward movement of the two clamping fingers 15; then the clamping device drives the spray head cover 1 to move downward, and at this time the second pipe-pushing cylinder 13 drives the second pneumatic clamping gripper 14 to move downward through the piston rod. During the downward movement of the soft straw 2, it always remains in a vertical state under the action of the clamping finger 15, so that it can accurately enter the bottle opening, and when the second pipe-pushing cylinder 13 moves to the lowest end, the clamping finger 15 releases the soft straw 2, and during the resetting process of the clamping device, the first pipe-pushing cylinder 12 and the second pipe-pushing cylinder 13 drive the second pneumatic clamping gripper 14 to reset.

[0036] Furthermore, the two clamping fingers 15 are provided with vertical downward arc grooves 16 facing each other at one end of the cover feeding guide rail 3. When the two clamping fingers 15 are merged, the two arc grooves 16 are combined into a hole for straightening the soft straw 2, which helps the soft straw 2 to always be located in the hole when the two clamping fingers 15 are closed, thereby ensuring that the soft straw 2 is always facing the bottle opening under the action of the two clamping fingers 15.

[0037] It is worth mentioning that a number of support slide bars 10 are vertically installed on the frame 4, and the second pipe-pulling cylinder 13 and the second pneumatic clamp 14 are both installed with a second balance frame 17 that slides with the support slide bars 10, which helps to stabilize the second pipe-pulling cylinder 13 and the second pneumatic clamp 14 during movement.

[0038] like Figure 2 , 4As shown, the positioning device includes two positioning cylinders 18 respectively installed at both ends of the conveyor belt and with two piston rods facing each other, and a positioning member 19 installed on the piston rod of the positioning cylinder 18 and used to position the bottle. The two positioning members 19 have arc grooves 16 vertically opened on the facing sides for clamping the bottle. When the two arc grooves 16 are combined, the bottle clamped by the positioning member 19 is just below the nozzle cover 1. When the bottle on the conveyor belt is identified, the conveyor belt stops running. At this time, the bottle is located between the two positioning cylinders 18. Then the two positioning cylinders 18 drive the two positioning members 19 to move toward each other through the piston rod, and the bottle is positioned under the arc grooves 16 of the two positioning members 19.

[0039] The working process and beneficial effects of the utility model are as follows: when the nozzle cover 1 with the soft straw 2 needs to be installed on the bottle, the nozzle cover 1 is transported by the cover feeding guide rail 3, and when the nozzle cover 1 moves to the position recognized by the infrared sensor 5 on the cover feeding guide rail 3, the cover feeding guide rail 3 stops moving, and when the bottle on the conveyor belt moves to the corresponding recognition position of the infrared sensor 5, the conveyor belt stops moving; then the positioning device positions and tightens the recognized bottle on the conveyor belt, and then the clamping device clamps the recognized nozzle cover 1 on the cover feeding guide rail 3 and clamps the nozzle cover 1 The clamp is positioned just above the bottle opening. At this time, the soft straw 2 is located above the bottle. Then, the tube-straightening device fits the soft straw 2 at the nozzle cover 1 and moves vertically, so that the tube-straightening device straightens the soft straw 2 vertically downward. At this time, the lower end of the soft straw 2 is facing the bottle opening. Then, the clamping device drives the nozzle cover 1 and the soft straw 2 to move downward. The soft straw 2 first enters the bottle. The tube-straightening device releases the soft straw 2. The clamping device drives the nozzle cover 1 to cover the bottle opening. Finally, the clamping device releases the nozzle cover 1 and the tube-straightening device moves up and resets. The positioning device releases the bottle.

[0040] In summary, the above-mentioned clamping device, the tube straightening device and the positioning device can effectively position the bottle, then clamp the spray head cover 1, and then straighten the soft straw 2, and finally accurately install the spray head cover 1 and the soft straw 2 on the bottle opening, thereby achieving automated mechanical operation, and the spray head cover 1 with the soft straw 2 can be accurately and efficiently installed on the bottle, effectively increasing work efficiency and reducing costs.
