[0001] This utility model belongs to the field of document bag production technology, and more specifically, it relates to a sealing device for document bag production. Background Technology

[0002] In the field of document bag production, edge sealing equipment is often used to seal the edges of document bags. In actual production, in order to improve production efficiency and reduce costs, it is often desirable for one machine to be suitable for document bags of various sizes. However, traditional edge sealing equipment for document bag production does not have the function of adjusting the width of the edge sealing device. As a result, when faced with document bags of different widths, it is impossible to adjust flexibly, and the equipment or molds must be changed frequently. This not only affects production efficiency and extends the production cycle, but also increases equipment wear and maintenance costs due to frequent equipment or mold changes, thus limiting the versatility and practicality of the equipment. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides an edge-sealing device for document bag production, which solves the technical problem that traditional edge-sealing devices for document bag production do not have an adjustable edge-sealing device width.

[0004] The purpose and effectiveness of this utility model's edge-sealing equipment for producing document bags are achieved through the following specific technical means:

[0005] An edge-sealing device for producing document bags includes a main frame, on which a belt roller assembly is mounted. A feeding frame is located at one end of the belt roller assembly, and a feeding component is installed within the feeding frame. Support plates are located on both sides of the belt roller assembly, and multiple optical shafts pass through the support plates. Two sets of bearing seats, an adjusting motor, and a control module are installed below the main frame. A bidirectional lead screw passes through the bearing seats, and the adjusting motor is gear-driven to the bidirectional lead screw. Adjusting plates are located on both sides of the main frame, and these adjusting plates are fitted onto the multiple optical shafts and the bidirectional lead screw. An edge-sealing component is installed above the adjusting plates. A proximity switch is installed at one end of each support plate, and a limit component is installed at the other end.

[0006] According to a preferred embodiment, the edge sealing assembly includes an upper pressure block and a lower pressure block. The lower pressure block is mounted on the adjustment plate, and the upper pressure block is positioned above the lower pressure block. Both of them have pressure grooves on their contact surfaces. The pressure grooves are serrated, and a heating wire is threaded through the bottom of the pressure grooves. Multiple sets of limiting rods are threaded through one side of both the upper and lower pressure blocks.

[0007] According to a preferred embodiment, the edge sealing assembly further includes a mounting block and an edge sealing cylinder. The mounting block is mounted on one side of the lower pressure block, and the edge sealing cylinder is mounted on the mounting block. The shaft end of the edge sealing cylinder is connected to the upper pressure block.

[0008] According to a preferred embodiment, the feeding assembly includes two sets of feeding plates, the feeding plates are disposed in the feeding frame, one end of the adjusting plate is provided with a guide plate, and one end of the feeding plate extends out of the feeding frame and is connected to the guide plate.

[0009] According to a preferred embodiment, the feeding assembly further includes a feeding roller and a feeding motor. The feeding roller is disposed below the feeding frame, and a feeding groove is provided at the bottom of the feeding frame. The feeding roller is engaged in the feeding groove. The feeding motor is mounted on the main frame, and a rubber wheel is sleeved on the shaft end of the feeding motor.

[0010] According to a preferred embodiment, the outer wall of the feeding roller is provided with a rubber layer, and the rubber wheel is in rolling friction connection with the feeding roller.

[0011] According to a preferred embodiment, the limiting component includes a limiting frame and a limiting cylinder. The limiting frame is mounted on the main frame, and the limiting cylinder is mounted upside down on the limiting frame. The shaft end of the limiting cylinder passes through the limiting frame and is connected to the limiting plate.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This utility model, through the design of the edge-sealing assembly, increases the contact area with the edge of the document bag by using serrated grooves on the contact surfaces of the upper and lower pressure blocks. An electric heating wire inserted below the grooves heats the edge of the document bag, allowing the user to seal the edge of the bag and improving the sealing capability of the device. After the document bag is conveyed to the designated position, the user can move the upper pressure block up and down using the edge-sealing cylinder to clamp and release the edge of the document bag between the upper and lower pressure blocks, enabling the user to complete the edge-sealing operation and improving the effectiveness of the device.

[0014] 2. When using this device, the user can guide the movement of the unsealed document bag via the feeding plate in the feeding assembly, allowing the user to convey the document bag to the belt roller assembly, improving the smoothness of the feeding process. Then, the feeding motor drives the rubber wheel to rotate, and the rolling friction between the rubber wheel and the feeding roller drives the feeding roller to rotate, enabling the device to deliver the document bag from the feeding frame to the sealing assembly. This provides the user with an automatic feeding method, improving the automation level of the device. Attached Figure Description

[0023] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solution of this utility model, but should not be used to limit the scope of protection of this utility model.

[0024] Example:

[0025] like Figures 1 to 6 As shown, this utility model provides a sealing device for document bag production, including a main frame 11. A belt roller assembly is mounted on the main frame 11, which is responsible for conveying document bags and enabling sealing operations on the device. A feeding frame 12 is placed at one end of the belt roller assembly. The feeding frame 12 contains a feeding component for storing and outputting unsealed document bags. Each side of the belt roller assembly has a set of support plates 13, which provide support and positioning. Multiple optical shafts pass through the support plates 13, guiding the movement of the adjusting plate 17. Two sets of bearing seats, an adjusting motor 14, and a control module 15 are installed below the main frame 11. The control module 15 can be a Raspberry Pi 4B control module.

[0026] A bidirectional lead screw 16 is installed inside the bearing housing, and an adjusting motor 14 is connected to the bidirectional lead screw 16 via gear transmission. When the adjusting motor 14 operates, it drives the bidirectional lead screw 16 to rotate. A set of adjusting plates 17 are installed on each side of the main frame 11. The adjusting plates 17 are fitted onto multiple optical shafts and the bidirectional lead screw 16. With the guidance of the optical shafts and the transmission of the bidirectional lead screw 16, the adjusting plates 17 can be adjusted in position on both sides of the main frame 11. An edge-sealing assembly is installed above the adjusting plates 17, which is responsible for sealing the document bag. A proximity switch 18 is installed at one end of the support plate 13. The proximity switch 18 can be an Omron E2E-X10ME1 type inductive proximity switch, used to detect whether the document bag has reached the designated position. A limit assembly is installed at the other end to limit the movement range of the document bag.

[0027] like Figures 2 to 4 As shown, the edge-sealing assembly consists of an upper pressure block 19 and a lower pressure block 21. The lower pressure block 21 is mounted on the adjusting plate 17, and the upper pressure block 19 is located above the lower pressure block 21. Both the upper pressure block 19 and the lower pressure block 21 have pressure grooves 22 on their opposing contact surfaces. These grooves 22 are serrated. This serrated design increases the contact area with the edge of the document bag, resulting in a better sealing effect. A heating wire 23 is threaded below the pressure groove 22. When energized, the heating wire 23 heats the edge of the document bag, allowing it to be better sealed under the pressure of the upper and lower pressure blocks. Multiple sets of limiting rods are threaded on one side of both the upper pressure block 19 and the lower pressure block 21. These limiting rods provide positioning and stability, ensuring the accurate relative position of the upper pressure block 19 and the lower pressure block 21 during operation and guaranteeing the quality of the edge sealing.

[0028] The edge sealing assembly also includes a mounting block 24 and an edge sealing cylinder 25. The mounting block 24 is installed on one side of the lower pressure block 21, providing a mounting position for the edge sealing cylinder 25. The edge sealing cylinder 25 is mounted on the mounting block 24, and its shaft end is connected to the upper pressure block 19. When the edge sealing cylinder 25 is working, the extension and retraction of its shaft end drives the upper pressure block 19 to move up and down, realizing the clamping and releasing action of the upper pressure block 19 and the lower pressure block 21 on the edge of the document bag, thereby completing the edge sealing operation.

[0029] like Figure 2 , Figure 5 As shown, the feeding assembly includes two sets of feeding plates 26, which are set inside the feeding frame 12 to guide the sealed document bag to move downwards. A guide plate 27 is provided at one end of the adjusting plate 17, and the guide plate 27 can slide within the feeding frame 12. One end of the feeding plate 26 extends out of the feeding frame 12 and is connected to the guide plate 27. When the adjusting plate 17 moves, the guide plate 27 drives the feeding plate 26 to move, causing the spacing between the two sets of feeding frames 12 to change synchronously. This accommodates document bags of different sizes and makes the feeding process of the document bag smoother.

[0030] The feeding assembly also includes a feeding roller 28 and a feeding motor 29. The feeding roller 28 is located below the feeding frame 12, and a feeding groove is provided at the bottom of the feeding frame 12. The feeding roller 28 is engaged in the feeding groove, and the top of the feeding roller 28 is located within the feeding frame 12. The feeding motor 29 is mounted on the main frame 11, and a rubber wheel 31 is sleeved on its shaft end. After the feeding motor 29 is started, it drives the rubber wheel 31 to rotate. The rubber wheel 31 and the feeding roller 28 are connected through rolling friction, thereby driving the feeding roller 28 to rotate. This connection method can effectively transmit power and ensure the smooth progress of the feeding process.

[0031] The outer wall of the feeding roller 28 is provided with a rubber layer, which increases the friction between the feeding roller 28 and the document bag. The top of the feeding roller 28 contacts the document bag in the feeding frame 12. When the feeding roller 28 rotates, it sends the document bag out of the feeding frame and is transported to the edge sealing assembly by the belt roller group.

[0032] like Figure 2 , Figure 6 As shown, the limiting assembly consists of a limiting frame 32 and a limiting cylinder 33. The limiting frame 32 is mounted on the main frame 11, providing mounting support for the limiting cylinder 33. The limiting cylinder 33 is mounted upside down on the limiting frame 32, with its shaft end passing through the limiting frame 32 and connecting to the limiting plate 34. When the limiting cylinder 33 is working, the extension and retraction of its shaft end drives the limiting plate 34 to move. The limiting plate 34 is C-shaped, with its opening facing downwards, and it is fastened to the belt roller assembly. When the limiting cylinder 33 extends, the limiting plate 34 moves downwards, restricting the movement of the document bag and creating working conditions for the edge sealing assembly.

[0033] The specific usage and function of this embodiment are as follows:

[0034] When using the edge-sealing equipment for producing document bags, first turn on the equipment. The control module 15 starts the belt roller assembly to convey the unsealed document bag located in the feeding frame 12. When the feeding roller 28 rotates under the drive of the feeding motor 29, the friction between the rubber layer and the document bag is used to feed the document bag from the feeding frame 12 onto the belt roller assembly.

[0035] The belt roller assembly continues to operate, conveying the document bag forward. When the proximity switch 18 detects that the document bag has reached the designated sealing position, the limit cylinder 33 is activated, and the shaft end extends to drive the limit plate 34 to move downward, locking onto the belt roller assembly, restricting the movement of the document bag, and stopping the document bag in front of the sealing assembly.

[0036] The control module 15 controls the operation of the sealing cylinder 25. The end of the sealing cylinder 25 extends and retracts, causing the upper pressure block 19 to move downwards and cooperate with the lower pressure block 21 to clamp the edge of the document bag. At the same time, the heating wire 23 is energized and heats up the edge of the document bag, so that it is sealed under the pressure of the upper and lower pressure blocks.

[0037] After sealing, the sealing cylinder 25 drives the upper pressure block 19 to rise, and the belt roller assembly continues to transport the sealed document bag to the next process. During this process, if adjustments are needed to accommodate different sized document bags, the adjusting motor 14 operates, driving the adjusting plate 17 to move via the bidirectional lead screw 16. The adjusting plate 17 then drives the guide plate 27, which in turn moves the feeding plate 26, changing the distance between the two sets of feeding plates 26. All components of the entire equipment work together to realize the process of document bags from storage, transportation, sealing, to re-feeding and storage, meeting the sealing requirements of document bag production.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments.
