Description

Technical Field

[0001] The present application relates to the technical field of packaging bag capping, and in particular to a vacuum compression packaging bag capping machine. Background Art

[0002] Vacuum compression storage bags are often used to package and store household items such as clothes and bedding. By vacuuming the packaged storage bags, on the one hand, the space occupied by storage can be reduced, and on the other hand, it can effectively slow down the problems of clothes in the storage bags getting damp, oxidized and discolored due to long-term storage.

[0003] Vacuum compression storage bags typically have a lid. The capping machine heat-seals the lid at the lid opening, and uses a vacuum pump to create a vacuum inside the bag during storage. The vacuum packaging bag capping machine includes a cap conveyor, a bag conveyor, and a capping device. Existing cap conveyors include a disc-shaped cap sorting device, in which a large number of caps rotate. As the disc-shaped cap sorting device delivers the caps to the cap guide slide, multiple caps move together toward the cap guide slide at the exit of the disc-shaped cap sorting device. This often results in multiple caps blocking the exit, causing the device to malfunction.

[0004] In response to the above-mentioned related problems, the inventor proposed a vacuum compression packaging bag capping machine. Utility Model Content

[0005] In order to ensure that the caps of vacuum compression packaging bags can be smoothly transported to the capping device for heat sealing and reduce the occurrence of blockage during the transmission process, the present application provides a vacuum compression packaging bag capping machine, which adopts the following technical solutions:

[0006] A vacuum compression packaging bag capping machine includes a packaging film transmission device, a capping cylinder arranged on the upper side of the packaging film transmission device, a capping box arranged on the ground on one side of the packaging film transmission device, a vertical conveyor belt, a blower fixed to the outer wall of one side of the conveyor belt, and a cover guide slide arranged on one side of the packaging film transmission device; one end of the conveyor belt extends into the capping box, and a plurality of bar-shaped slots are fixed on the conveyor belt. One end of the cover guide slide is arranged on one side of the conveyor belt, and the other end of the cover guide slide extends below the packaging film transmission device to directly below the capping cylinder.

[0007] By adopting the above technical solution, one end of the vertical conveyor belt extends into the capping box, and the caps in the capping box can be picked up during the rotation of the conveyor belt. A bar slot is provided on the vertical conveyor belt. Since one side of the capping of the vacuum compression bag is raised, only the back side of the raised side of the capping can be clamped in the bar slot. If the raised side is close to the bar slot, the cap will fall back into the capping box due to the imbalance of the center of gravity during the transportation of the conveyor belt. The caps in the capping box are sorted by the setting of the bar slot. The blower blows the caps that have been sorted to the cap guide slide and then transmits the caps one by one in an orderly manner toward the packaging film transmission device, so that the cap sorting and transmission of the caps are smoother, and the occurrence of cap blockage during the transmission process is effectively reduced.

[0008] Optionally, a baffle is provided on the outer cover of the upper end of the conveyor belt, the outlet end of the blower is located at one end of the baffle, and the other end of the baffle is connected to one end of the guide cover slide.

[0009] By adopting the above technical solution, when the conveyor belt transports the completed cover to the blower, the blower blows the cover from the gap between the baffle and the conveyor belt to the cover guide slide. The setting of the baffle can prevent the cover from falling off during the blowing process of the blower.

[0010] Optionally, the upper side of the guide cover slide is S-shaped.

[0011] By adopting the above technical solution, the S-shaped slideway ensures that the convex side of the caps after capping is transported to the bottom of the packaging film transmission device, which is convenient for heat sealing between the caps and the packaging film.

[0012] Optionally, the interior of the capping box is bucket-shaped, and one end of the conveyor belt is close to the bottom wall of the capping box.

[0013] By adopting the above technical solution, the caps in the bucket-shaped capping box are gathered toward the bottom end of the capping box, making it convenient for the conveyor belt to pick up the caps in the capping box.

[0014] Optionally, a hair roller is rotatably connected to an outer wall of one side of the cover guide slide close to the packaging film transmission device.

[0015] By adopting the above technical solution, the hair roller is arranged on the outer wall of the guide cover slide close to the packaging film transmission device, which can control the number of press covers entering under the packaging film transmission device and prevent the press covers from being blocked on the guide cover slide under the packaging film transmission device.

[0016] Optionally, a stepping motor is provided on one side of the bristle roller, and an output end of the stepping motor is fixedly connected to the rotating shaft of the bristle roller.

[0017] By adopting the above technical solution, the stepper motor controls the rotation of the hair roller to push the pressure cap to move under the pressure cap cylinder. Every time a pressure cap is installed, the hair roller pushes the pressure cap forward to fill the gap, effectively preventing the pressure cap from getting blocked and crowded on the guide cover slide below the pressure cap cylinder.

[0018] Optionally, it also includes a threaded screw, a sliding block is fixed to the top of the capping cylinder, the sliding block is threadedly connected to the threaded screw, and the capping cylinder is slidably connected to the upper side of the packaging film transmission device along the threaded screw.

[0019] By adopting the above technical solution, the capping cylinder is slidably connected to the upper side of the packaging film transmission device through the threaded connection between the sliding block and the threaded screw. The position of the capping can be adjusted to change the capping position, which can adapt to different capping process requirements and improve the adaptability of the capping machine.

[0020] Optionally, one end of the threaded screw is fixedly connected to a handwheel.

[0021] By adopting the above technical solution, the setting of the handwheel makes it convenient for the operator to rotate the threaded screw, thereby adjusting the position of the gland cylinder on the threaded screw.

[0022] Optionally, a photoelectric door is fixedly connected to the top outer wall of the gland cylinder.

[0023] By adopting the above technical solution, a detection component is provided inside the photoelectric door, which can accurately detect the position of the cover opening and then reflect the signal to the capping cylinder to control the capping cylinder to perform heat-sealing installation on the cap.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. The caps in the capping box are sorted and transported by setting a vertical conveyor belt. A bar slot is set on the vertical conveyor belt. Only the back side of the raised side of the cap can be snapped into the bar slot. Otherwise, the cap will fall back into the capping box due to the imbalance of the center of gravity during the conveyor belt transportation process. The caps in the capping box are sorted by the bar slot. The blower blows the sorted caps to the cap guide slide and then transmits the caps one by one in an orderly manner, making the sorting and transmission of caps smoother and effectively reducing the occurrence of cap blockage during the transmission process.

[0026] 2. The stepper motor controls the rotation of the hair roller to push the gland to move under the gland cylinder. After each gland is installed, the hair roller pushes the gland forward to fill the gap, effectively preventing the gland from getting stuck and crowded on the guide slideway under the gland cylinder.

[0027] 3. The capping cylinder is connected to the upper side of the packaging film transmission device through sliding with the threaded screw, and the position of the capping can be adjusted to change the capping position, which can adapt to different capping process requirements and improve the adaptability of the capping machine.

[0033] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0034] This embodiment discloses a vacuum compression packaging bag capping machine, which is used to cap the surface of the vacuum compression packaging bag during the manufacturing process of the vacuum compression packaging bag. Figure 1 As shown, it includes a frame 1, a capping device 4 fixed to one side of the frame 1, a packaging film transmission device 5 rotatably connected to the frame 1, a lifting device 2 for sorting caps, and a transmission component 3 for transmitting the caps from the lifting device 2 to the lower side of the capping device 4.

[0035] The capping device 4 is arranged on the upper side of the packaging film transmission device 5, and the lifting device 2 is arranged on the ground on one side of the frame 1. The packaging film transmitted by the packaging film transmission device 5 is provided with cover openings 51 (such as Figure 3 As shown in FIG, one side of the pressing cover of the vacuum compression packaging bag is convex, and when the pressing cover device 4 heat-seals the pressing cover and the packaging film at the cover opening 51, the convex side of the pressing cover faces upward.

[0036] like Figure 1 and Figure 2As shown, the lifting device 2 includes a capping box 21 for holding the caps to be capped and a vertical conveyor belt 22. The length direction of the conveyor belt 22 is arranged perpendicular to the horizontal plane. A plurality of strip slots 221 are fixed to the conveyor belt 22. The plurality of strip slots 221 are arranged at intervals on the surface of the conveyor belt 22. The length direction of each strip slot 221 is perpendicular to the length direction of the conveyor belt 22. One end of the conveyor belt 22 extends into the capping box 21.

[0037] During the rotation of the conveyor belt 22, the side of the pressure cap with a larger outer diameter can be stuck in the strip groove and move with the conveyor belt 22, and the raised side of the pressure cap will not be stuck in the strip groove, so that the conveyor belt 22 can pick up the pressure caps in the pressure cap box 21 and sort the multiple pressure caps so that the pressure caps being transported are those with the raised side away from the surface of the conveyor belt 22.

[0038] In order to make the conveyor belt 22 more efficient in picking up the caps, the interior of the capping box 21 is bucket-shaped. Under the influence of the capping's own gravity, the capping can gather at the bottom of the capping box 21 near one end of the conveyor belt 22 and be picked up by the conveyor belt 22.

[0039] The transmission assembly 3 is disposed on one side of the upper end of the conveyor belt 22. A blower 23 is fixedly connected to the outer wall of the other side of the upper end of the conveyor belt 22. The blowing direction of the blower 23 is the same as the length direction of the strip groove. The outer wall of the upper end of the conveyor belt 22 is covered with a baffle 24, one end of which is connected to the transmission assembly 3. The conveyor belt 22 transports the glands upward to the blower 23. The blower 23 blows the glands in the strip grooves within the baffle 24 out into the transmission assembly 3. The transmission assembly 3 continues to transport the glands. The baffle 24 can prevent the glands from falling when blown by the blower 23 and prevent the glands from flipping in the baffle 24.

[0040] like Figure 1 and Figure 3 As shown, the transmission component 3 includes a guide cover slide 31, and the guide cover slide 31 includes a vertical slide 311 and a horizontal slide 312. The vertical slide 311 completely surrounds the pressure cover inside and the pressure cover will not flip over in the vertical slide 311. One end of the vertical slide 311 is fixed to one side of the baffle 24, and the other end of the vertical slide 311 is fixed to one end of the horizontal slide 312 and is connected to the horizontal slide 312. The end of the horizontal slide 312 away from the vertical slide 311 is located below the packaging film conveying device, and the width of the guide cover slide 31 only allows the transportation of a single pressure cover.

[0041] In order to slow down the sliding speed of the gland in the vertical slide 311 , the vertical slide 311 is S-shaped, and the blower 23 blows the gland in the strip groove of the conveyor belt 22 into the vertical slide 311 , and the gland slides from the vertical slide 311 to the horizontal slide 312 .

[0042] To orderly convey the multiple glands to the bottom of the packaging film conveyor 5, the outer wall of the horizontal slide 312 where it connects to the vertical slide 311 is curved, and the bottom wall is slightly inclined. This allows the glands to slide from the vertical slide 311 into the horizontal slide 312 and move along the horizontal slide 312 toward the packaging film conveyor 5. A hair roller 33 is rotatably connected to the outer wall of the horizontal slide 312 on the side near the packaging film conveyor 5, which is used to control the orderly movement of the glands toward the bottom of the packaging film conveyor 5. A stepper motor 32 is fixed to one side of the hair roller 33. The output end of the stepper motor 32 is fixed to the rotating shaft of the hair roller 33 to drive the hair roller 33 to rotate.

[0043] like Figure 4 As shown, the capping device 4 includes a threaded screw 41 and a capping cylinder 44. The threaded screw 41 is passed through the frame 1. The length direction of the threaded screw 41 is perpendicular to the length direction of the packaging film transmission device 5. A sliding block 43 is fixedly connected to the upper end of the capping cylinder 44. The sliding block 43 is passed through the threaded screw 41 and is threadedly connected to the threaded screw 41. One end of the threaded screw 41 is fixedly connected to a handwheel 42. When the handwheel 42 is turned, the sliding block 43 slides along the length direction of the threaded screw 41. A photoelectric gate 45 is fixedly connected to the upper outer wall of the capping cylinder 44, and a detection component capable of detecting the cover opening 51 is provided in the photoelectric gate 45. A vacuum suction cup (not shown in the figure) is provided at the output end of the capping cylinder 44, and a heat sealing block 441 is provided on the outer shell of the vacuum suction cup. When the photoelectric gate 45 detects the cover opening 51, the packaging film transmission device 5 stops, and the capping cylinder 44 can suck the cap on the horizontal slide 312 below the packaging film transmission device 5 to the cover opening 51, and heat-seal the cap and the packaging film through the heat sealing block 441.

[0044] When a vacuum compression packaging bag capping machine in the present application is in use, one side of the capping box 21 is clamped in the strip groove on the conveyor belt 22, and the conveyor belt 22 picks up the capping in the capping box 21, and the blower 23 blows the capping into the guide cap slide 31, and the capping moves along the guide cap slide 31 to the packaging film transmission device 5 just below the packaging film cover 51; when the photoelectric gate 45 detects the existence of the cover 51, the packaging film transmission device 5 stops, and the vacuum suction cup in the capping cylinder 44 sucks up the capping on the guide cap slide 31 and heat-seals the cap and the packaging film at the cover 51 through the heat sealing block 441. After the heat sealing is completed, the packaging film transmission device 5 continues to move, and the stepping motor 32 controls the hair roller 33 to rotate to transmit the capping to the bottom of the packaging film transmission device 5, and the capping device 4 repeats the previous process to cap the packaging film.

[0045] It can be understood that when the internal detection component of the photoelectric gate 45 detects the presence of the cover 51, the packaging film transmission device 5 stops, and the vacuum suction cup and the heat sealing block 441 are provided at the output end of the capping cylinder 44 to suck up the cover and heat-seal it with the packaging film. This is the existing technology and will not be elaborated in this application.

[0046] The implementation principle of this embodiment is:

[0047] A plurality of strip-shaped slots 221 are evenly arranged on the vertical conveyor belt 22 of the pressure cap lifting device 2. The side of the pressure cap with a larger outer diameter can be snapped into the strip-shaped slot 221, and the raised side of the pressure cap cannot be snapped into the strip-shaped slot 221. The conveyor belt 22 continuously picks up the pressure caps from the pressure cap box 21. The pressure caps picked up by the conveyor belt 22 all have their raised sides facing away from the surface of the conveyor belt 22. The pressure caps are sorted by the strip-shaped grooves of the conveyor belt 22, and the blower 23 blows the pressure caps into the transmission component 3. The transmission component 3 conveys the pressure caps to the bottom of the packaging film transmission device 5 with their raised sides facing upward.

[0048] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
