Description

Technical Field

[0001] The present application relates to the technical field of sealing devices, and in particular to a heating sealing device for a vapor phase rust-proof bag. Background Art

[0002] When the metal to be rust-proofed is sealed and stored in the gas phase rust-proof bag, the rust-proof particles in the rust-proof bag are vaporized into gas, forming a protective film on the surface of the protected metal, cutting off the possibility of metal ions contacting with water and oxygen, thereby achieving the rust-proof effect;

[0003] For example, the patent with publication number CN219339923U specifically discloses a heating sealing device for environmentally friendly vapor phase rust-proof bags. The device conveys the rust-proof bags to be sealed to a conveying device through a grabbing device, and then the conveying device conveys the rust-proof bags to the bottom of the paper sealing part, and then the telescopic cylinder pushes the hot pressing sealing plate downward, and then the motor drives the pressing wheel to press the sealing position.

[0004] However, in the implementation process of the above patent, since an object has been placed inside the anti-rust bag, the anti-rust bag will be stretched open. Therefore, it is necessary to pre-press the opening before sealing it to prevent the opening of the anti-rust bag from being in an open state during sealing, which will cause unevenness after sealing, and directly affect the appearance quality of the anti-rust vapor phase bag.

[0005] Therefore, it is necessary to provide a gas phase rust-proof bag heating and sealing device to solve the above problems.

[0006] It should be noted that the above information disclosed in this background technology section is only for understanding the background technology of the present application concept, and therefore, it may contain information that does not constitute the prior art. Summary of the invention

[0007] Based on the above problems existing in the prior art, the problem to be solved by the present application is: to provide a vapor phase rust-proof bag heating and sealing device to achieve the effect of pre-flattening the rust-proof bag.

[0008] The technical solution adopted by the present application to solve its technical problems is: a vapor phase anti-rust bag heating and sealing device, including a mounting box; a conveying assembly, which is mounted on the mounting box and is suitable for transporting anti-rust bags; a heat sealing assembly, which is mounted on the mounting box and is suitable for sealing anti-rust bags; a pre-pressing assembly, which is mounted on the mounting box and is suitable for pre-pressing anti-rust bags, the pre-pressing assembly comprising: a mounting frame, which is mounted on the mounting box, a slot is provided on one side of the mounting frame, and at least two groups of conveying rollers are rotatably installed inside the mounting frame; and two groups of movable plates, which are movably arranged inside the mounting frame, and at least two groups of pressing rollers are rotatably installed between the two groups of movable plates.

[0009] Furthermore, the conveying assembly includes a conveying frame installed on the installation box, and a conveying part is arranged inside the conveying frame.

[0010] Furthermore, the heat sealing assembly includes a heat sealing portion installed on the installation box, and a baffle is installed on one side of the installation box, and the baffle is located above the heat sealing portion.

[0011] Furthermore, a scraping component is installed on the pre-pressing component.

[0012] Furthermore, the scraping assembly includes a scraper installed on a mounting frame, the scraper is slightly inclined, and a conveying plate is installed on the mounting frame.

[0013] The beneficial effect of the present application is that the present application provides a vapor phase anti-rust bag heating and sealing device, which flattens the anti-rust bag at the sealing portion to be sealed through a pre-pressing component, thereby preventing the sealing portion from being unable to fit tightly after heat sealing due to unevenness, gaps or wrinkles between the materials, thereby achieving the effect of pre-pressing the anti-rust bag.

[0022] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0023] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0024] like Figure 1-Figure 2 As shown, the present application provides a vapor phase anti-rust bag heating sealing device, including an installation box 1, and a pre-pressing component 4 is fixedly installed on the installation box 1, and the pre-pressing component 4 is used for the pre-pressing and flattening operation of the anti-rust bag. At the same time, a conveying component 3 is fixedly installed on the installation box 1, and the conveying component 3 is used to convey the anti-rust bag, and a heat sealing component 2 is fixedly installed on the installation box 1, and the heat sealing component 2 is used for the heat sealing operation of the anti-rust bag. Specifically:

[0025] like Figure 2-Figure 3 As shown, the pre-pressing assembly 4 includes a mounting frame 41 fixedly mounted on the mounting box 1, and a slot for the anti-rust bag to pass through is opened on one side of the mounting frame 41, and multiple groups of conveying rollers 44 are rotatably mounted inside the mounting frame 41, and each group of conveying rollers 44 are connected by chains and sprockets. At the same time, a motor (not shown in the figure) is fixedly mounted on the mounting frame 41, and the output end of the motor is fixedly connected to one group of conveying rollers 44, and one group of conveying rollers 44 is driven to rotate by the motor, thereby driving the remaining conveying rollers 44 to rotate through the chains and sprockets, so as to transport the anti-rust bags;

[0026] At the same time, two groups of movable plates 42 (not shown in the figure) are movably arranged inside the mounting frame 41, and multiple groups of pressing rollers 43 are rotatably installed between the two groups of movable plates 42. It should be noted that the multiple groups of pressing rollers 43 correspond to the multiple groups of conveying rollers 44 one by one, so as to smooth the opening of the anti-rust bag;

[0027] like Figure 1 As shown, the conveying assembly 3 includes a conveying frame 31 fixedly mounted on the installation box 1, and a conveying portion 32 is arranged inside the conveying frame 31. The conveying portion 32 is an existing belt conveyor, and the specific structure and principle are not described in detail here.

[0028] like Figure 1As shown, the heat sealing assembly 2 includes a heat sealing portion 22 installed on the installation box 1. The heat sealing portion 22 is an existing heat sealing machine. The specific structure and principle are not described in detail here. At the same time, a baffle 21 is fixedly installed on one side of the installation box 1, and the baffle 21 is located above the heat sealing portion 22 to block dust to ensure the operation of the hot air portion;

[0029] In summary, when sealing the gas phase rust-proof bag, the part of the rust-proof bag to be sealed is placed in the notch of the mounting frame 41. At this time, the rust-proof bag is on the conveying mechanism, and then the conveying mechanism is started to drive the rust-proof bag to move, and the rust-proof bag is pre-pressed and flattened by the pre-pressing component 4. At this time, the rust-proof bag is in a closed state, and then the rust-proof bag is heat-pressed and sealed by the heat-sealing component 2, and finally transported out by the conveying component 3. It should be noted that the notch of the pre-pressing component 4 and the inlet of the heat-sealing part are on the same axis to ensure that the rust-proof bag is heat-sealed;

[0030] In the above process, the pre-pressing component 4 can only flatten the anti-rust bag. However, due to errors in transportation, some areas of the anti-rust bags are in a folded state. At this time, pre-pressing makes the folded part fold at the sealed part, which makes it impossible to form a tight seal. The added air and moisture will penetrate into the bag, affecting the anti-rust effect. In order to solve this problem, a scraping component 5 is fixedly installed on the pre-pressing component 4. The scraping component 5 is used to scrape the anti-rust bag flat. Specifically:

[0031] like Figure 3 As shown, the scraping assembly 5 includes a scraper 52 fixedly mounted on the mounting frame 41, the upper end of the scraper 52 is inclined to facilitate scooping up the folded part, and a conveying plate 51 is fixedly mounted on the mounting frame 41, the conveying plate 51 is used to resist the anti-rust bag, it should be noted that the gap between the scraper 52 and the conveying plate 51 is equivalent to the thickness of the anti-rust bag;

[0032] Before each pre-pressing, the anti-rust bag to be sealed passes between the scraper 52 and the conveying plate 51. At this time, the scraper 52 scoops up the folded part of the anti-rust bag and makes the folded part of the anti-rust bag in a horizontal state through the space between the scraper 52 and the conveying plate 51. Then, the anti-rust bag can be pre-pressed and heat-sealed.

[0033] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
