Description

Technical Field

[0001] This utility model relates to the field of packaging machinery, and in particular to a dustproof cover hanging packaging machine. Background Technology

[0002] The dustproof rubber cap of the milk powder can prevent external air and moisture from entering the can, thus providing moisture protection and ensuring that the milk powder remains fresh within its shelf life and will not deteriorate due to moisture. The dustproof rubber cap has a good seal with the can body, making it less prone to powder leakage, air leakage, and oxidation. It also reduces the accumulation of dust and dirt at the can opening during transportation and storage, ensuring better hygiene. Current technology primarily uses dust cap capping machines to complete the capping and packaging of dust caps and cans. These machines typically use a dust cap conveyor belt to transport the dust caps to the capping mechanism. The continuous conveying of the dust cap conveyor belt enables continuous capping operations. This belt conveyor method requires the dust caps to be continuously fed onto the conveyor belt. Currently, dust caps are typically fed onto the conveyor belt by automatically sliding off from a material support. This method suffers from the problem of dust caps easily stacking and clogging, frequently requiring machine downtime for maintenance and affecting the high-efficiency continuous production line. Furthermore, various sizes of milk powder cans have different dimensions, resulting in different dust cap sizes. Currently, the main method is to completely disassemble and replace various capping components to match different sized dust caps. This process is cumbersome and delays production, and needs improvement. Utility Model Content

[0031] Example 1, see appendix Figure 1-2 A dust cover hanging packaging machine includes a belt conveyor 002 fixedly installed in the middle of the frame 001, a synchronous clamping device disposed above the belt conveyor, and a sliding cover device disposed obliquely above the synchronous clamping device. The synchronous clamping device includes a symmetrically arranged synchronous belt assembly 003, and the sliding cover device includes an adsorption feeding mechanism 07 and a cover hanging slide 01. The adsorption feeding mechanism is installed at the upper end of the cover hanging slide. A capping roller assembly is provided at the outlet of the cover hanging slide 01. The capping roller assembly includes at least three capping rollers 004 with progressively decreasing heights. The three capping rollers can press the dust cover step by step, gradually pressing it against the port of the milk powder can.

[0032] The sliding cover device, two synchronous belt assemblies 003, and the cover pressing wheel assembly are all mounted on four symmetrically arranged circular columns 101. The sliding cover device is connected to the two circular columns 101 at one end via lifting seat A 104. The height of the sliding cover device can be adjusted on the circular columns via lifting seat A. The cover pressing wheel assembly is connected to the slide rails of the two circular columns 101 at the other end via lifting seat B 105. The height of the cover pressing wheel assembly can be adjusted on the circular columns via lifting seat B. One synchronous belt assembly 003 is connected to the slide rails of the two outer circular columns 101 via lifting seat C 106. The other synchronous belt assembly 003 is connected to the slide rails of the two inner circular columns 101 via lifting seat D 107. The heights of the two synchronous belt assemblies can be adjusted via lifting seat C and lifting seat D, respectively.

[0033] Two plates A 102 and two plates B 103 are symmetrically arranged at the upper ends of the circular column 101. A lead screw A 108 is rotatably connected to the middle of the lifting seat A 104. The middle of the lead screw A is threadedly connected to the corresponding plate A 102. A manual wheel is connected to the upper end of the lead screw A 108. Rotating this manual wheel drives the lead screw A to rotate. The lead screw A drives the lifting seat A 104 to rise or fall along the circular column 101 via the thread. A lead screw B 109 is rotatably connected to the middle of the lifting seat B 105. The middle of the lead screw B 109 is threadedly connected to the corresponding plate A 102. A manual wheel is connected to the upper end of the lead screw B. Rotating this manual wheel drives the lifting seat A 104 to rise or fall along the circular column 101. The wheel drives the lead screw B109 to rotate, and the lead screw B109 drives the lifting seat B105 to rise or fall along the circular column 101 via a thread. The middle of the lifting seat C106 is connected to the lead screw C110, which is threadedly connected to the corresponding plate B103. The middle of the lifting seat D107 is rotatably connected to the lead screw D, which is also threadedly connected to the corresponding plate B103. Both the lead screw C110 and lead screw D have manual wheels connected to their upper ends. Rotating these manual wheels drives the two lead screws to rotate, and the two lead screws drive the lifting seats C106 and D107 to rise or fall along the circular column 101 via threads. Therefore, the height of each part of this capping packaging machine can be adjusted by rotating the manual wheel, allowing for fine-tuning of the capping accuracy and enabling the use of various sizes of dust caps for capping packaging.

[0034] When the dust cap hanging packaging machine of this embodiment is working, the dust cap is continuously drawn down and fed into the hanging slide 01 by the adsorption feeding mechanism 07. At the same time, the conveyor device 002 continuously conveys the milk powder can forward. When the milk powder can enters between the two synchronous belt assemblies 003, it is clamped and conveyed forward. When the milk powder can passes the lower end of the hanging slide 01, it will catch the dust cap that slides out of the slide. The dust cap slides out and is initially attached to the upper port of the milk powder can. Then it enters the multiple capping rollers 004 arranged in parallel. Under the downward pressure of the capping rollers, it is pressed tightly to the upper port of the milk powder can, realizing continuous and efficient dust cap packaging operation.

[0035] Example 2, see appendix Figure 3-8 This embodiment is basically the same as Embodiment 1, and the similarities will not be repeated. The difference is that: the cover slide 01 includes a slide support and two L-shaped slide rails 2 symmetrically installed in the slide support. The slide support includes two symmetrically arranged side guard plates 11 and a top plate 12 connected between the upper ends of the two side guard plates 11. A cover slide rail 3 is provided directly above the two L-shaped slide rails 2. The upper end of the L-shaped slide rail 2 has a triangular support plate 21, and the two triangular support plates form a V-shaped inlet. The dust cover is introduced into the slide rail through the V-shaped inlet. A seat plate is provided on the outer side of the lower end of the L-shaped slide rail 2. An L-shaped retaining rod 4 is provided on the seat plate. The upper end of the L-shaped retaining rod is hinged to the seat plate, so that the L-shaped retaining rod 4 has a certain swing space on the outer side of the L-shaped slide rail 2. A cover is provided in the middle of the L-shaped retaining rod 4. The upper ends of the two hanging rods 41 are connected by a tension spring 42, which provides elastic tension to the two L-shaped clamping rods. The lower end of the cover slide rail 3 is provided with an elastic pressure plate 5, and a support slide rod 51 is vertically provided on the surface of the cover slide rail 3. The elastic pressure plate 5 is slidably connected to the support slide rod 51 through a sliding hole 52 at its end. The size of the sliding hole is larger than the cross-sectional size of the support slide rod. The upper end of the support slide rod 51 is provided with a limiting block 53. A spring 54 is sleeved in the middle of the support slide rod 51. The elastic pressure plate 5 can slide up and down along the support slide rod 51 and has a certain swing space. The spring 54 provides elastic downward pressure to the elastic pressure plate 5. The upper end of the cover slide rail 3 is provided with a guide plate 31, which is located directly above the V-shaped inlet.

[0036] An auxiliary elongated hole 55 is provided in the middle of the elastic pressure plate 5, and an auxiliary slide rod 56 is provided in the auxiliary elongated hole. A limiting block 53 is provided at the upper end of the auxiliary slide rod, and an auxiliary spring 57 is provided in the middle of the auxiliary slide rod 56. The auxiliary spring 57 is used to assist in pressing down the elastic pressure plate 5 and increase its elastic downward force.

[0037] A photoelectric sensor is mounted on the bottom of the V-shaped inlet via a bracket. This photoelectric sensor monitors in real time whether a dust cover has entered the slide. If the slide is blocked, it can provide timely feedback.

[0038] The end of the cover slide rail 3 is provided with a U-shaped seat 32. The U-shaped seat 32 is provided with a support rod that is fixedly connected to the top plate 12. The cover slide rail 3 is fixedly supported by the support rods at both ends. The support rod is a screw 33. The screw extends into the through hole in the middle of the U-shaped seat. Nuts 34 are provided on the screw 33 at the lower and upper parts of the U-shaped seat 32 to lock it. The height of the cover slide rail 3 is adjusted by turning the lower nut 34 to push the U-shaped seat 32. After adjustment, the U-shaped seat 32 is locked by the upper nut 34.

[0039] At least two transverse guide posts 61 are provided between the lower parts of the two side guard plates 11. A folding plate 22 is provided in the middle of the L-shaped slide rail 2. The sliding sleeve 62 provided on the folding plate is slidably connected to the transverse guide post 61, so that the two L-shaped slide rails 2 can slide along the guide post to adjust the spacing. An adjustment mechanism is provided between the two transverse guide posts 61. The adjustment mechanism includes a bidirectional screw 63 rotatably connected between the two side guard plates 11. A nut sleeve 64 connected to the bidirectional screw 63 is provided in the middle of the two folding plates 22. The nut sleeve on one side is connected to the forward thread on the bidirectional screw, and the nut sleeve 64 on the other side is connected to the reverse thread on the bidirectional screw 63. A handwheel 65 is provided at one end of the bidirectional screw 63.

[0040] In this embodiment, when the dust cover slide 01 is in use, the dust cover enters the slide through the V-shaped inlet and slides downwards. When the dust cover reaches the lower end of the slide, the inner ends of the L-shaped locking rods 4 on both sides lock onto the sides of the dust cover, stopping the slide. At the same time, the elastic pressure plate 5 above presses against the middle of the upper surface of the dust cover. Both sides and the upper part of the dust cover are subjected to elastic pressure and are elastically pressed. When the packaging can passes the dust cover from the conveying device, its front edge can hook onto the inner side of the dust cover. When the tension on the dust cover is greater than the elastic pressure it receives, it is hooked, pulled out, and fastened to the upper port of the packaging can, awaiting the subsequent pressing mechanism. Press it tight; when it is necessary to adjust the slide rail size to match the new specification dust cover, rotate the handwheel 65 to drive the double-acting screw 63 to rotate. The double-acting screw 63 drives the two L-shaped slide rails 2 synchronously through the nut sleeves 64 on both sides. The two L-shaped slide rails 2 slide synchronously towards or away from each other to adjust the distance between them. Tighten the nut 34 at the bottom of the U-shaped seat 32 to push or release the U-shaped seat 32 to adjust the height of the cover slide rail 3. After the height is adjusted to the correct position, tighten the nut 34 at the top to lock the U-shaped seat 32, thereby adjusting the distance between the cover slide rail 3 and the L-shaped slide rail 2, so that the slide rail can be quickly matched with dust covers of different sizes.

[0041] Example 3, see appendix Figure 9-13This embodiment is basically the same as Embodiment 1, and the similarities will not be repeated. The difference is that the adsorption-type feeding mechanism 07 includes a circular support 7 and several limiting components evenly distributed in the inner ring of the circular support 7. The limiting components include a stop bar 71 arranged along the generatrix of the circular support 7 and a finger-shaped baffle 72 connected to the lower end of the stop bar. The lower end of the finger-shaped baffle 72 is an inwardly inclined plate end 73, which extends into the space between each stop bar 71 and can block the dust cover placed between each stop bar 71. Two vertical support plates 8 are evenly distributed on the outer side of the circular support 7, and a sliding groove is connected between the middle of the two vertical support plates. The slide plate 81 is inclined and can automatically slide down when the dust cover falls onto the slide plate 81. The middle of the slide plate 81 is provided with an adsorption hole 82. A horizontal support plate 83 is provided between the lower ends of the two vertical support plates 8. A cylinder 84 is installed in the middle of the horizontal support plate 83. The upper end of the piston rod of the cylinder is connected to a U-shaped bracket 85. A suction cup assembly 86 corresponding to the adsorption hole 82 is installed on the upper part of the U-shaped bracket. The size of the adsorption hole is larger than the size of the suction cup assembly. A docking support 96 is provided on one side of the annular support 7. The length of the stop bar 71 on the side near the docking support 96 is greater than the length of the stop bar on the other side.

[0042] A mounting surface is provided on the outer side of the lower end of the stop rod 71. A bolt rod 74 is vertically connected to the upper part of the mounting surface. A sleeve hole 75 provided at the upper end of the finger-shaped baffle 72 fits into the bolt rod 74. The size of the sleeve hole is larger than the size of the bolt rod. A downward pressure spring A 76 is fitted on the bolt rod 74 to press down on the finger-shaped baffle 72. The downward pressure spring A 76 presses down on the finger-shaped baffle 72, allowing the inner end of the finger-shaped baffle 72 to extend under the inner ring of the circular bracket 7 to block the sealing cover. A long guide rod 77 is vertically connected to the lower part of the mounting surface. A long hole 78 is provided in the middle of the finger-shaped baffle 72, which fits into the long guide rod 77. A limit nut 79 is threaded to the upper end of the long guide rod. A downward pressure spring B 80 is provided in the middle of the long guide rod 77. The downward pressure spring B assists the downward pressure spring A 76 to provide strong elastic support for the finger-shaped baffle 72, thereby enabling it to hold more dust covers and increase the capacity of the feeding mechanism.

[0043] The stop bar 71 is connected to the annular bracket 7 via a radial plate 91. An adjustment elongated hole 92 is provided in the middle of the radial plate 91 along its length direction. A screw a 93 is provided in the adjustment elongated hole and is threadedly connected to the annular bracket 7. After loosening the screw a 93, the radial plate 91 can be adjusted in position along the radial direction of the annular bracket 7 to accommodate and store dust covers of different diameters.

[0044] The lower part of the vertical support plate 8 is provided with a vertically elongated hole 94 along its length. A screw 95 is provided in the vertically elongated hole and is threaded to the end face of the horizontal support plate 83. After the screw 95 is loosened, the horizontal support plate 83 can be vertically adjusted between the vertical support plates 8, thereby adjusting the height of the cylinder 84 and the suction cup assembly 86, ensuring that the suction cup assembly 86 can be firmly attached to the bottom surface of the dust cover.

[0045] When the adsorption-type feeding mechanism 07 of this embodiment is working, dust covers are stacked between each baffle 71. The inclined plate end 73 at the lower end of the finger-shaped baffle 72 provided at the lower end of each baffle 71 can hold the edge of the bottom dust cover, thereby limiting the position of the dust cover. Then, the cylinder 84 is activated, and the cylinder moves the suction cup assembly 86 upward. After the suction cup assembly 86 passes through the adsorption hole 82, it is firmly attached to the inner surface of the dust cover. Then, the cylinder 84 drives the suction cup assembly 86 to move the dust cover downward. When the downward pulling force is greater than the elastic resistance of the dust cover, the finger-shaped baffle 72 compresses the spring 54 and swings outward. The dust cover is pulled out from between each finger-shaped baffle 72 by the suction cup assembly 86. Then, the suction cup assembly 86 releases it and drops it onto the slide plate 81. This method of adsorption and feeding can achieve the desired result.
