DETAILED DESCRIPTION

[0018] The technical solutions 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 a part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application usually described and marked in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.

[0019] The utility model discloses a roller sealing structure for a packaging machine, which is mainly used in scenarios where the roller sealing structure of a traditional packaging machine is used, and the roller locking structure is complex, and the sealing loading process and the unloading process after sealing are cumbersome to adjust and time-consuming, thus affecting the sealing efficiency of the packaging material.

[0020] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 A roller sealing structure of a packaging machine includes a base 1 and a mounting frame 3 installed on the top of the base 1, and also includes: a linkage roller pressing mechanism: the linkage roller pressing mechanism is arranged on the inner wall of one side of the mounting frame 3, and the linkage roller pressing mechanism is provided with a first pressing wheel 9 and a second pressing wheel 10; a movable locking mechanism: the movable locking mechanism includes two sliding rods 15 arranged on the inner walls of both sides of the mounting frame 3, and the outer walls of the two sliding rods 15 are sleeved with a fixed sleeve block 4 and a movable sleeve block 5, a connecting rod is installed on the outer wall of one side of the movable sleeve block 5, and a return spring 14 is sleeved on the outer wall of the connecting rod, a connecting frame is provided on the outer wall of one side of the mounting frame 3, one end of the connecting rod passes through the mounting frame 3 and is connected to the inside of the connecting frame, a pin shaft 13 is provided on the inner wall of the connecting frame, the pin shaft 13 is inserted into one end of the connecting rod, and a handle 8 is installed on the outer wall of one side of the connecting frame.

[0021] Specifically, the first pressing wheel 9 and the second pressing wheel 10 on the linked roller pressing mechanism are connected to the fixed sleeve block 4 and the movable sleeve block 5 respectively. During the sealing operation, the first pressing wheel 9 and the second pressing wheel 10 are close to each other, so that the packaging material can be clamped between the two, and then heat-sealed. After the current packaging operation is completed, if a new packaging material needs to be replaced, the handle 8 can be pulled to use the lever principle to pull the connecting rod to drive the movable sleeve block 5 to move toward the side away from the fixed sleeve block 4, so that the first pressing wheel 9 and the second pressing wheel 10 are separated from each other, so that the material can be unloaded after the packaging is completed and the new packaging material can be loaded. The whole process is simple to operate and the efficiency of loading and unloading is high.

[0022] It should be noted that the reset spring 14 can play a supporting and rebounding role. After replacing the packaging material, slowly release the handle 8, and the movable sleeve block 5 will be close to the fixed sleeve block 4 again under the rebound action of the reset spring 14, without the need for complicated locking adjustment.

[0023] Among them, a spherical stopper is provided at one end of the handle 8, which effectively prevents the handle 8 from slipping out of the hand during the process of pulling the handle 8.

[0024] Reference Figure 1 , Figure 2 and Figure 3 In a preferred embodiment, the linkage rolling mechanism includes a rotating shaft connected to the inner wall of the fixed sleeve block 4 and the movable sleeve block 5 by a bearing, and the same end of the two rotating shafts is respectively connected to a driving gear 6 and a driven gear 7, the driving gear 6 and the driven gear 7 are meshed with each other, and a second bevel gear 12 is provided on one side outer wall of the driving gear 6, and a motor 2 is provided on one side outer wall of the base 1, and one end of the output shaft of the motor 2 is connected to a rotating rod, and one end of the rotating rod is connected to a first bevel gear 11 through a mounting frame 3, and the first bevel gear 11 and the second bevel gear 12 are meshed with each other, and the ends of the two rotating shafts away from the driving gear 6 and the driven gear 7 are connected to a connecting disk, and the first pressure wheel 9 and the second pressure wheel 10 are respectively installed on one side outer wall of the two connecting disks.

[0025] Specifically, through the interlocking rolling mechanism, a single motor 2 can be used to drive the two rotating shafts to rotate simultaneously, and the meshing action of the driving gear 6 and the driven gear 7 can make the two rotating shafts rotate in opposite directions, thereby matching the pressing of the first pressing wheel 9 and the second pressing wheel 10 on the packaging material.

[0026] It should be noted that one end of the rotating shaft connected to the driving gear 6 is connected to the mounting frame 3 by a bearing, and one end of the rotating shaft connected to the driven gear 7 is only in contact with the mounting frame 3, so that when the movable sleeve block 5 moves, the connection of the driven gear 7 will not be affected. When the movable sleeve block 5 is away from the fixed sleeve block 4, the driving gear 6 and the driven gear 7 are also separated. When the movable sleeve block 5 is close to the fixed sleeve block 4, the driving gear 6 and the driven gear 7 are maintained in a meshing state again.

[0027] Reference Figure 1 and Figure 4 In a preferred embodiment, a blocking rod 16 is provided on an outer wall of one side of the fixed sleeve block 4, one end of the blocking rod 16 is bent and vertically downward, and the blocking rod 16 is located between the two connecting plates.

[0028] Specifically, the blocking rod 16 can block the packaging material clamped therein on one side, and its vertical downward structure can align the packaging material with the edge of the packaging material to ensure the neatness of the sealing process.

[0029] Reference Figure 1In a preferred embodiment, a heating component is disposed inside the first pressing wheel 9 and the second pressing wheel 10, and the heating component can provide heat to the outer wall of the first pressing wheel 9 and the second pressing wheel 10 to facilitate sealing of the packaging material.

[0030] Working principle: When in use, first pull the handle 8, use the lever principle to pull the connecting rod to drive the movable sleeve block 5 to move toward the side away from the fixed sleeve block 4, so that the first pressing wheel 9 and the second pressing wheel 10 are separated from each other, and the material to be packaged is clamped therein. The provided blocking rod 16 can block the packaging material clamped therein on one side, and its vertical downward structure can align the packaging material on one side in conjunction with the edge of the packaging material. The motor 2 drives the rotating rod to rotate, and then drives the driving gear 6 to rotate under the meshing action of the first bevel gear 11 and the second bevel gear 12. Due to the meshing of the driving gear 6 and the driven gear 7, the first pressing wheel 9 and the second pressing wheel 10 are driven to rotate toward each other while keeping the pressed packaging material, so as to perform stable heat sealing on the packaging material. After the sealing of the current material is completed, pull the handle 8, pull the connecting rod to drive the movable sleeve block 5 to move toward the side away from the fixed sleeve block 4, thereby realizing the separation of the first pressing wheel 9 and the second pressing wheel 10 from each other, reloading new packaging material, and repeating the above operation to continue to complete the sealing operation.

[0031] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited to this. The replacement can be a replacement of part of the structure, device, method step, or a complete technical solution. Equivalent replacement or change based on the technical solution of the utility model and its utility model concept should be included in the protection scope of the utility model.
