Description

Technical Field

[0001] This utility model relates to the field of filter element edge bonding technology, and in particular to a differential feeding system for an edge bonding machine. Background Technology

[0002] In the filter element production process, edge bonding involves applying adhesive to the edge strips and then pasting them onto the pleated paper surface at the beginning and end of the filter element. Since hot melt adhesive bonding requires a certain amount of pressure, and the gaps between the pleats at the beginning and end of the pleated paper prevent the generation of bonding pressure during edge bonding, current processes either use dedicated edge bonding fixtures or manual operation with a scraper. The former requires the design of a fixture circulation system, which greatly increases the complexity of the machine, while the latter is a manual operation, requiring an additional two functions to be added to a single machine.

[0003] Therefore, in view of the shortcomings of the existing technology, it is necessary to design a differential speed feeding system for the edge-sealing machine to solve the above problems. Utility Model Content

[0004] To overcome the shortcomings of the prior art, this utility model provides a differential feeding system for an edge-sealing machine. Through differential feeding design, it achieves precise bonding between the edge strip and the glued side of the product, thereby improving the edge-sealing quality and production efficiency.

[0005] To achieve the above and other related objectives, the technical solution provided by this utility model is: a differential speed feeding system for an edge-sealing machine, used to convey edge strips to the adhesive-coated side of the product for edge sealing, comprising:

[0006] A side strip feeding mechanism is used to feed the side strip along a first direction;

[0007] An edge-pulling mechanism is used to pull the edge strip along a second direction;

[0008] The first direction and the second direction are set at an angle, and the feeding speed of the edge feeding mechanism is greater than the edge pulling speed of the edge pulling mechanism.

[0009] A preferred technical solution is as follows: the edge strip feeding mechanism includes an edge strip roller, an infeed guide wheel, an edge-fitting guide wheel, and a feeding drive device; an edge strip in a coiled configuration is rotated on the edge strip roller, and the end of the edge strip is guided by the infeed guide wheel and fed to the edge-fitting guide wheel in the first direction, and then guided by the edge-fitting guide wheel in the second direction to the edge-pulling mechanism; the feeding drive device is located between the infeed guide wheel and the edge-fitting guide wheel, and is used to drive the edge strip to be fed out at a feeding speed.

[0010] The preferred technical solution is that the adhesive side of the product is fed along the second direction and is attached to the edge strip.

[0011] Due to the application of the above technical solution, the beneficial effects of this utility model are as follows:

[0012] This utility model provides a differential speed feeding system for an edge-sealing machine. By setting the differential speed between the edge strip feeding mechanism and the edge-pulling mechanism, the edge strip forms a specific arc-shaped motion trajectory during the conveying process. When the feeding speed is greater than the edge-pulling speed, the excess edge strip will be recessed inward along the last fold of the product, thereby tightly fitting the folded paper structure of the product and preventing the edge strip from becoming loose or wrinkled. At the same time, the feeding length is equal to the edge-pulling movement distance, which can ultimately straighten the edge strips on both sides, ensuring that the edge-sealing position is flat and firm. This design significantly improves the edge-sealing accuracy and product qualification rate, reduces the adjustment cost in the production process, is suitable for automated edge-sealing production lines, and effectively improves production efficiency.

[0017] Example:

[0018] like Figure 1 As shown, according to a general technical concept of this utility model, a differential speed feeding system for an edge-sealing machine is provided, used to convey the edge strip to the adhesive-coated edge-sealing side of the product 300 to achieve edge sealing, including:

[0019] Edge strip feeding mechanism 1, used to feed edge strips along a first direction 100;

[0020] Edge pulling mechanism 2 is used to pull the edge strip along the second direction 200;

[0021] The first direction 100 and the second direction 200 are set at an angle, and the feeding speed of the edge strip feeding mechanism 1 is greater than the edge pulling speed of the edge pulling mechanism 2.

[0022] like Figure 1 As shown, in an exemplary embodiment of this utility model, the edge strip feeding mechanism 1 includes an edge strip roller 11, an infeed guide wheel 12, an edge-fitting guide wheel 13, and a feeding drive device 14. An edge strip in a rolled configuration is rotated on the edge strip roller 11. The end of the edge strip is guided by the infeed guide wheel 12 and fed to the edge-fitting guide wheel 13 along a first direction 100. Then, guided by the edge-fitting guide wheel 13, it is fed to the edge-pulling mechanism 2 along a second direction 200. The feeding drive device 14 is located between the infeed guide wheel 12 and the edge-fitting guide wheel 13 and is used to drive the edge strip to be fed out at a feeding speed. When the feeding speed is greater than the edge-pulling speed, the excess edge strip will be recessed inward along the last fold of the product 300, thereby tightly fitting the folded paper structure of the product 300 and preventing the edge strip from becoming loose or wrinkled.

[0023] like Figure 1 As shown, in an exemplary embodiment of this utility model, the adhesive-coated edge side of product 300 is fed along the second direction 200 and is attached to the edge strip.

[0024] It should be noted that the edge feeding mechanism 1 and the edge pulling mechanism 2 are both existing technologies. Any structure that can achieve feeding and edge pulling, and that uses differential feeding to achieve edge application in this application, should be within the scope of protection of this application.

[0025] Therefore, this utility model has the following advantages:

[0026] This utility model provides a differential speed feeding system for an edge-sealing machine. By setting the differential speed between the edge strip feeding mechanism and the edge-pulling mechanism, the edge strip forms a specific arc-shaped motion trajectory during the conveying process. When the feeding speed is greater than the edge-pulling speed, the excess edge strip will be recessed inward along the last fold of the product, thereby tightly fitting the folded paper structure of the product and preventing the edge strip from becoming loose or wrinkled. At the same time, the feeding length is equal to the edge-pulling movement distance, which can ultimately straighten the edge strips on both sides, ensuring that the edge-sealing position is flat and firm. This design significantly improves the edge-sealing accuracy and product qualification rate, reduces the adjustment cost in the production process, is suitable for automated edge-sealing production lines, and effectively improves production efficiency.
