Abstract
Description
Technical Field
[0001] This utility model relates to the field of packaging equipment, and in particular to a packaging bag sealing mechanism. Background Technology
[0002] The packaging of steel balls includes outer packaging and inner packaging. The outer packaging is usually a cardboard box or wooden box, and the inner packaging is a plastic bag. After the steel balls are put into the plastic bag, the lid is closed, and the packaging is completed.
[0003] The existing packaging method involves repeatedly rolling the opening of the bag after the steel balls are placed inside. This requires a large amount of manpower and increases production costs. Utility Model Content
[0004] To address the shortcomings of existing technologies, the main objective of this invention is to overcome these deficiencies by disclosing a packaging bag sealing mechanism. The mechanism includes a frame, two sets of first actuators, two sets of second actuators, and a sealing assembly. The two sets of first actuators are positioned on either side of the frame along the X-axis, folding the packaging bag opening towards the center along the Y-axis. The second actuators are mounted on the frame via lifting components and are located on either side of the Y-axis, folding the packaging bag opening towards the center along the X-axis. The sealing assembly welds and fixes the overlapping portion of the packaging bag.
[0005] Furthermore, the first execution component includes a first bracket, a first cylinder, and a first push plate. The first cylinder is mounted on the frame via the first bracket, and the first push plate is mounted on the first cylinder. The first cylinder drives the first push plate to move horizontally.
[0006] Furthermore, the end of the second push plate is provided with a rounded chamfer.
[0007] Furthermore, the second actuation component includes a second bracket, a second cylinder, and a second push plate. The second cylinder is mounted on the lifting component via the second bracket, and the second push plate is mounted on the second cylinder. The second cylinder drives the second push plate to move horizontally.
[0008] Furthermore, the second push plate has an anti-cavity groove. When the two second push plates overlap, the anti-cavity groove forms a through hole that allows the sealing component to act on the packaging bag.
[0009] Furthermore, the end of the second push plate is provided with a rounded chamfer.
[0010] Furthermore, the lifting assembly includes a lifting plate, a first guide rod, a first guide sleeve, and a third cylinder. The first guide sleeve and the third cylinder are mounted on the frame. The first guide rod is slidably connected to the first guide sleeve. The lifting plate is mounted on the first guide rod and the third cylinder, and the third cylinder drives the lifting plate to move up and down.
[0011] Furthermore, at least two sets of the first guide rod and the first guide sleeve are provided.
[0012] Furthermore, the sealing assembly includes a second guide rod, a second guide sleeve, a fourth cylinder, a mounting plate, and a hot melt block. The second guide sleeve and the fourth cylinder are respectively disposed on the lifting assembly. The second guide rod is slidably connected to the second guide sleeve. The mounting plate is disposed on the second guide rod and the fourth cylinder. The fourth cylinder drives the mounting plate to move up and down. The hot melt block is disposed on the mounting plate. The hot melt block is used to heat-melt and bond the packaging bag parts together.
[0013] The beneficial effects achieved by this utility model are:
[0014] This invention utilizes two sets of actuators, along with a sealing assembly, to fold and secure the opening of a packaging bag. Working in conjunction with a conveyor belt, it enables automatic packaging of the inner bag and facilitates sealing of the outer bag, significantly reducing manpower and improving packaging efficiency. The sealing assembly employs a heat-sealing method to melt the opening of the packaging bag, achieving rapid and secure sealing. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.
[0022] A packaging bag sealing mechanism, such as Figures 1-4 As shown, the device includes a frame 1, two sets of first execution components 2, two sets of second execution components 3, and a sealing component 4. The two sets of first execution components 2 are arranged on both sides of the frame 1 in the X-axis direction. The first execution components 2 are used to fold the opening of the packaging bag towards the center along the Y-axis direction. The second execution components 3 are arranged on the frame 1 through the lifting component 5 and are located on both sides in the Y-axis direction. The second execution components 3 are used to fold the opening of the packaging bag towards the center along the X-axis direction. The sealing component 4 is used to weld and fix the overlapping part of the packaging bag.
[0023] In one embodiment, such as Figures 1-4 As shown, the first execution component 2 includes a first bracket 21, a first cylinder 22 and a first push plate 23. The first cylinder 22 is mounted on the frame 1 via the first bracket 21, and the first push plate 23 is mounted on the first cylinder 22. The first cylinder 22 drives the first push plate 23 to move horizontally.
[0024] In the above embodiments, such as Figures 1-4 As shown, the end of the second push plate 23 is provided with a rounded chamfer. The rounded chamfer protects the packaging bag and prevents sharp edges from pushing the opening of the packaging bag and folding it, thus damaging the surface of the packaging bag.
[0025] In one embodiment, such as Figures 1-4 As shown, the second actuator 3 includes a second bracket 31, a second cylinder 32, and a second pusher plate 33. The second cylinder 32 is mounted on the lifting assembly 4 via the second bracket 31, and the second pusher plate 33 is mounted on the second cylinder 32. The second cylinder 32 drives the second pusher plate 33 to move horizontally. The lifting assembly 4 controls the up-and-down movement of the second actuator 3. The bag sealing mechanism works in conjunction with the conveying mechanism. A conveying mechanism is provided between the two first actuators 2 to transport the filled bags. The lifting mechanism ensures that the second actuator 3 does not affect the operation of the conveying mechanism.
[0026] In one embodiment, such as Figures 1-4 As shown, the second push plate 33 has a clearance groove 331. After the two second push plates 33 overlap, the clearance groove 331 forms a through hole that allows the sealing component 4 to act on the packaging bag.
[0027] In one embodiment, such as Figures 1-4 As shown, the end of the second push plate 33 is provided with a rounded chamfer.
[0028] In one embodiment, such as Figures 1-4 As shown, the lifting assembly 5 includes a lifting plate 51, a first guide rod 52, a first guide sleeve 53, and a third cylinder 54. The first guide sleeve 53 and the third cylinder 54 are mounted on the frame 1. The first guide rod 52 is slidably connected to the first guide sleeve 53. The lifting plate 51 is mounted on the first guide rod 52 and the third cylinder 54. The third cylinder 54 drives the lifting plate 51 to move up and down.
[0029] In the above embodiments, such as Figures 1-4 As shown, at least two sets of the first guide rod 52 and the first guide sleeve 53 are provided. In this embodiment, two sets of the first guide rod 52 and the second guide sleeve 53 are provided, arranged diagonally.
[0030] In one embodiment, such as Figures 1-4 As shown, the sealing assembly 4 includes a second guide rod 41, a second guide sleeve 42, a fourth cylinder 43, a mounting plate 44, and a heat-melting block 45. The second guide sleeve 42 and the fourth cylinder 43 are respectively mounted on the lifting assembly 5. The second guide rod 41 is slidably connected to the second guide sleeve 42. The mounting plate 44 is mounted on the second guide rod 41 and the fourth cylinder 43. The fourth cylinder 43 drives the mounting plate 44 to move up and down. The heat-melting block 45 is mounted on the mounting plate 44 and heat-melts and bonds the packaging bag together. The heat-melting tube 45 is an electric heating block that melts and bonds the packaging bag together at high temperature, thus fixing it and preventing the packaging bag from lifting and affecting the outer packaging box.
[0031] When using this utility model, such as Figures 1-4 As shown, the packaging bag sealing mechanism is used to fold and secure the opening of the inner packaging bag, facilitating the sealing of the outer packaging. The packaging bag sealing mechanism is mounted on a conveyor belt. The conveyor belt moves the filled packaging bag to the sealing mechanism, where the first actuator 2 guides and bends the two sides of the packaging bag towards the center. After completion, one of the first actuator 2s resets, while the other remains in place. The second actuator 3 then actuates, bending the other two sides of the packaging bag towards the center. Through holes are formed at the second push plates 33 of the two second actuators 3, allowing the sealing component to secure the packaging bag. The first push plate 23 of the other first actuator 2 supports the hot melt block 45, ensuring the packaging bag opening is securely fixed. After completion, all components reset, awaiting the next cycle.
[0032] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of implementation of the present utility model. Any modifications or equivalent substitutions to the present utility model without departing from the spirit and scope thereof shall be covered within the protection scope of the claims of the present utility model.
