Abstract
Description
Technical Field
[0001] This utility model relates to the field of sealing machine technology, and in particular to a bagging module for a sealing machine. Background Technology
[0002] Lamination technology, a widely used process for preserving and enhancing documents and photos, relies on heating and pressurizing to tightly adhere a special lamination film to the surface of an item, forming a transparent and sealed protective layer. The lamination machine, as a key piece of equipment for this process, directly impacts work efficiency and product quality through its performance and ease of operation. Among the many components of a lamination machine, the bagging module—the device that guides the double-layer composite film to accurately wrap the item to be laminated and feeds it into the heat-pressing mechanism—is of paramount importance in its design.
[0003] Currently, the traditional bagging operation of laminating machines is often quite cumbersome when processing double-layer laminating films that need to be pre-made into bags. Operators need to manually and carefully pass the front end of the double-layer film through a series of guiding components. The most critical part is that the film needs to be passed under a specific triangular plate and then pulled out from above it to form the correct wrapping path. This process is not only time-consuming and labor-intensive, requiring a high level of operator skill, but it is also very easy for the film to wrinkle, shift, or even get stuck due to misalignment or improper operation, which directly affects the subsequent laminating effect. Therefore, it is necessary to design a bagging module for laminating machines. Utility Model Content
[0004] The purpose of this invention is to provide a bagging module for a sealing machine to solve the problems existing in the prior art.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:
[0006] A bagging module for a sealing machine includes a worktable with upward protrusions extending from the top of its left and right sides. Each protrusion has a through-hole extending from left to right. Two protrusions are connected to the same belt conveyor. A first triangular plate is spaced apart on the upper side of the belt conveyor, and a second triangular plate is spaced apart on the lower side. The first and second triangular plates are arranged parallel to each other. A first traction unit and a third traction unit are spaced apart on the top of the second triangular plate, and a second traction unit is spaced apart on the bottom of the second triangular plate. The first and second traction units cooperate to pull the bag from back to front, and the third traction unit pulls the bag from right to left.
[0007] By adopting the above technical solution, the sealing machine uses a double-layer film. The material on the belt conveyor needs to pass through two parallel triangular plates (first and second) to enter between the double-layer film and complete the sealing process. This device uses a first traction unit and a second traction unit to guide the double-layer film through the second triangular plate. After the first and second traction units pull the double-layer film to the front edge of the second triangular plate, a third traction unit pulls the inner bottom of the double-layer film. Then, the first and second traction units return to their original positions, and the third traction unit pulls the double-layer film from the bottom of the belt conveyor from right to left, pulling it out from the top of the second triangular plate. Thus, the operator only needs to align the double-layer film before feeding it into the pressing roller of the next process, avoiding the tedious process of putting the double-layer film on the second triangular plate. This saves manpower and time costs and helps improve the efficiency of the device.
[0008] In a further embodiment, the first traction unit, the second traction unit, and the third traction unit all have the same structure. The first traction unit and the second traction unit are arranged symmetrically vertically, and the third traction unit is arranged between the first traction unit and the second traction unit. The third traction unit is perpendicular to the first traction unit and the second traction unit.
[0009] In a further embodiment, the first traction unit includes a first telescopic rod, a second telescopic rod, a connecting pipe, a first main suction nozzle, a second main suction nozzle, and auxiliary suction nozzles. Multiple auxiliary suction nozzles are provided. The first and second telescopic rods are spaced apart. The first and second main suction nozzles are respectively fixedly installed at the movable ends of the first and second telescopic rods. The ends of the first and second main suction nozzles that are close to each other are connected to the same connecting pipe. Multiple auxiliary suction nozzles are fixedly installed at the bottom end of the connecting pipe, and the multiple auxiliary suction nozzles are evenly connected to the connecting pipe.
[0010] In a further embodiment, one end of both the first and second main suction nozzles is connected to an air tube, and the other end of the air tube is connected to an air pump.
[0011] By adopting the above technical solution, the vacuum pump has the functions of suction and air pumping. When the membrane needs to be suctioned, the vacuum pump draws air, which creates negative pressure in the main suction nozzle and the auxiliary suction nozzle, thereby sucking up the double membrane. When the membrane is no longer needed, the vacuum pump releases air, which restores the main suction nozzle and the auxiliary suction nozzle to normal pressure, thereby no longer sucking up the double membrane.
[0012] In a further embodiment, the fixing parts of both the first telescopic rod and the second telescopic rod are fixedly installed on the top of the workbench by a support frame.
[0013] In a further embodiment, the right-angled sides of the first and second triangles are located on the left rear side.
[0014] In summary, this utility model has the following beneficial effects:
[0015] 1. The double-layer film passes through the second triangular plate through the first and second traction units. After the first and second traction units pull the double-layer film to the front edge of the second triangular plate, the third traction unit pulls the inner bottom of the double-layer film. Then the first and second traction units return to their original positions, and the third traction unit pulls the double-layer film out from the bottom of the belt conveyor from right to left. The double-layer film is pulled out from the top of the second triangular plate. Thus, the operator only needs to tidy up and align the double-layer film before sending it into the pressing roller of the next process. This avoids the tedious process of putting the double-layer film on the second triangular plate, which can save manpower and time costs and help improve the efficiency of the device.

[0022] Example 1:
[0023] like Figures 1-3 As shown, a bagging module of a sealing machine includes a worktable 1. The top of the left and right sides of the worktable 1 has upward protrusions, and the protrusions are provided with through holes that pass through the left and right sides. The two protrusions are connected to the same belt conveyor 2. The upper side of the belt conveyor 2 is provided with a first triangular plate 3 at intervals, and the lower side of the belt conveyor 2 is provided with a second triangular plate 4 at intervals. The first triangular plate 3 and the second triangular plate 4 are arranged in parallel. The top of the second triangular plate 4 is provided with a first traction unit 5 and a third traction unit 6 at intervals, and the bottom of the second triangular plate 4 is provided with a second traction unit 7 at intervals. The first traction unit 5 and the second traction unit 7 cooperate with each other to pull the bag from back to front, and the third traction unit 6 is used to pull the bag from right to left.
[0024] The first traction unit 5, the second traction unit 7, and the third traction unit 6 have identical structures. The first traction unit 5 and the second traction unit 7 are arranged symmetrically vertically, and the third traction unit 6 is located between the first traction unit 5 and the second traction unit 7. The third traction unit 6 is perpendicular to the first traction unit 5 and the second traction unit 7. The first traction unit 5 includes a first telescopic rod 51, a second telescopic rod 52, a connecting pipe 53, a first main suction nozzle 54, a second main suction nozzle 55, and auxiliary suction nozzles 56. Multiple auxiliary suction nozzles 56 are provided. The first telescopic rod 51 and the second telescopic rod 52 are arranged alternately, and the first main suction nozzle 54 and the second main suction nozzle 55 are arranged alternately. 55 are respectively fixedly installed at the movable ends of the first telescopic rod 51 and the second telescopic rod 52. The ends of the first main suction nozzle 54 and the second main suction nozzle 55 that are close to each other are connected to the same connecting pipe 53. Multiple auxiliary suction nozzles 56 are fixedly installed at the bottom end of the connecting pipe 53. Multiple auxiliary suction nozzles 56 are evenly connected to the connecting pipe 53. One end of the first main suction nozzle 54 and the second main suction nozzle 55 are connected to an air pipe, and the other end of the air pipe is connected to an air pump. The fixed parts of the first telescopic rod 51 and the second telescopic rod 52 are fixedly installed on the top of the workbench 1 by a support frame. The right-angled sides of the first triangle 3 and the second triangle 4 are set on the left rear side.
[0025] Specific implementation process: Before bagging begins, the first, second, and third traction units are in their initial positions. When bagging begins, the vacuum pump starts to draw air, creating negative pressure in the first and second traction units' main suction nozzles and auxiliary suction nozzles. The first traction unit sucks up the top of the double-layer film, and the second traction unit sucks up the bottom, thus unfolding the double-layer film. Then, the movable ends of the first and second telescopic rods drive the main suction nozzles to move, pulling the double-layer film to the front edge of the second triangular plate. Next, the first and second telescopic rods of the third traction unit move synchronously, driving the first and second main suction nozzles and multiple auxiliary suction nozzles to pull the interior of the double-layer film. At the bottom, the first main suction nozzle, the second main suction nozzle, and multiple auxiliary suction nozzles of the first and second traction units release the double-layer film. Then, the first and second telescopic rods return to their original positions. Afterward, the third traction unit pulls the double-layer film from the bottom of the belt conveyor from right to left and from the top of the second triangular plate. Thus, the operator can easily obtain the bottom film of the double-layer film. After a simple adjustment and alignment of the pulled-out double-layer film, it can be sent into the pressing roller of the next process. Then, the first and second telescopic rods of the third traction unit reset. The whole process avoids the tedious process of putting the double-layer film on the second triangular plate, saving manpower and time costs and improving the efficiency of the device.
