Description

Technical Field

[0001] This utility model relates to the field of intelligent manufacturing packaging machine technology, and in particular to a combined drive linkage mechanism for a high-speed heavy film FFS packaging machine. Background Technology

[0002] With the continuous development of intelligent manufacturing, FFS (Form-Fill-Seal) bag-making packaging machines have emerged and are widely used in industries such as chemicals, food, and building materials. However, due to the inner and outer layers of the heavy-duty packaging bags (such as thick film materials like PE and PP), misalignment of the inner and outer layers is prone to occur during the progressive conveying, bag making, and packaging processes. Traditional FFS packaging machines, when dealing with such high-speed, heavy-load conditions, also suffer from a lack of sufficient clamping, guiding, and conveying mechanisms, leading to easy material spillage, low automation levels, and the need for significant manpower and resources. This can even affect the normal operation of other mechanisms on the production line. Therefore, designing suitable mechanical structures to adapt to the structural characteristics of heavy-duty packaging bags and achieving automated processing is a current research hotspot and challenge in the packaging field. Utility Model Content

[0003] This utility model discloses a combined drive linkage mechanism for a high-speed heavy film FFS packaging machine. It uses a servo motor to precisely drive the entire mechanism and employs a customized cam disk to achieve coordinated movement of multiple linkages. Multiple mounting holes on the cam disk allow for customization of the time allotted for various processing steps within a single cycle. This design also significantly reduces the complexity and space constraints of the overall structure. Furthermore, the mechanism integrates a bag-making module, a bag-opening module, a feeding module, and a sealing module. Used in conjunction with a conveyor belt, the periodic rotation of the cam enables integrated bag making, opening, feeding, sealing, and cooling of heavy film packaging bags. Unlike conventional FFS packaging machines, this significantly improves the automation level of the overall process and effectively saves manpower and material costs. In summary, it solves the problems in the background technology.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0005] This utility model discloses a combined drive linkage mechanism for a high-speed heavy film FFS packaging machine, comprising a support frame and a servo motor. The servo motor is mounted on the top of the support frame near one of its edges. A vertical frame is mounted on the top of the support frame, and a drive shaft is rotatably mounted inside the vertical frame. The drive shaft is connected to the servo motor. A customized mechanical cam disk is provided at one end of the drive shaft, and a drive linkage is hinged to the customized mechanical cam disk. The top of the support frame is provided with multiple sets of bearing seats, and a first driven linkage, a second driven linkage, a third driven linkage, a fourth driven linkage, a fifth driven linkage, and a sixth driven linkage are rotatably mounted on the multiple sets of bearing seats respectively.

[0006] A secondary shaft is installed inside the upright frame. The secondary shaft is located above the drive shaft. An end cap for fixing the secondary shaft is provided on one side of the upright frame. A seventh driven link is hinged to one end of the secondary shaft. An eighth driven link is hinged to the other end of the seventh driven link. The other end of the eighth driven link is hinged to the outside of the third driven link.

[0007] The support frame is equipped with a bag-making module, a bag-opening module, a material feeding module, and a sealing module below it, and the bag-making module, bag-opening module, material feeding module, and sealing module are all fixedly connected to each other with multiple driven linkages.

[0008] Furthermore, the customized mechanical cam disk has multiple mounting holes, one of which is hinged to the active connecting rod.

[0009] Furthermore, the mounting holes are arranged in an arc-shaped array, and the center of the arc-shaped array of the mounting holes is consistent with the axis of the drive shaft.

[0010] Furthermore, a sealing and cooling position is provided below the support frame, which is close to the sealing module and located below the servo motor.

[0011] The present invention has the following advantages over the prior art:

[0012] This technical solution uses a servo motor to precisely drive the entire mechanism and designs a customized cam disk to achieve the coordinated movement of multiple linkages. By designing multiple mating mounting holes on the cam disk, it is possible to customize the time of multiple processing steps within a cycle. This design also greatly reduces the complexity of the overall structure and space constraints.

[0021] Reference Figures 1-4A combined drive linkage mechanism for a high-speed heavy film FFS packaging machine includes a support frame 1 and a servo motor 2. The servo motor 2 is mounted on the top of the support frame 1 near one of its edges. A vertical frame 3 is mounted on the top of the support frame 1. An active shaft 5 is rotatably mounted inside the vertical frame 3. The active shaft 5 is connected to the servo motor 2. A customized mechanical cam disk 4 is provided at one end of the active shaft 5. An active linkage 8 is hinged at the customized mechanical cam disk 4. Multiple sets of bearing seats 17 are provided on the top of the support frame 1.

[0024] In the specific implementation process, the entire mechanism is precisely driven by a servo motor 2. A customized cam disk is designed to achieve the coordinated movement of multiple linkages. By designing multiple mating spaces on the cam disk, it is possible to customize the time of multiple processing processes within a cycle. This design also greatly reduces the complexity of the overall structure and space constraints. Based on this, the mechanism integrates a bag-making module 18, a bag-opening module 19, a feeding module 20, and a sealing module 21 into one unit. It works in conjunction with a conveyor belt. With the periodic rotation of the cam, the bag-making, bag-opening module 19, feeding, sealing, and cooling of heavy film packaging bags can be integrated. Unlike conventional FFS packaging machines, this greatly improves the automation level of the overall process and effectively saves manpower and material costs.

[0025] The customized mechanical cam disk 4 has multiple mounting holes 22 so that the drive shaft 5 can have multiple mounting options, thereby realizing the customized reciprocating motion of the overall structure in different working areas;

[0026] The multiple mounting holes 22 are arranged in an arc-shaped array, and the center of the arc-shaped array of the multiple mounting holes 22 is consistent with the axis of the drive shaft 5 so that the mounting position of the drive shaft 5 can be adjusted evenly.

[0028] Among them, the support frame 1 is mainly used to provide support and installation position for the servo motor 2 and other motion mechanisms;

[0029] Among them, the servo motor 2 is mainly used to provide power for the entire drive linkage mechanism. By driving the drive shaft 5 and the customized mechanical cam disk 4 to rotate, it drives the drive linkage 8 to reciprocate, and finally drives multiple other driven linkages to complete the coordinated motion (multiple driven linkages are connected to each other through transmission hinges to achieve the purpose and effect of coordinated motion).

[0030] Among them, the support frame 3 is mainly used for fixing and installing structural components such as servo motor 2, drive shaft 5, auxiliary shaft 6 and end cover 7;

[0034] Among them, the sealing module 21 is fixedly connected with multiple driven linkages and is responsible for the sealing process in the fourth step of the high-speed heavy film FFS packaging machine.

[0035] Among them, such as Figures 2-4 As shown, as the customized cam disk rotates counterclockwise, it drives the active connecting rod 8 to reciprocate, which in turn drives multiple driven connecting rods to cooperate in motion, thereby enabling the bag making module 18, bag opening module 19, material feeding module 20 and sealing module 21 to complete the relevant operations on the heavy film packaging bag below.

[0036] In this invention, a servo motor 2 is used to drive the combined drive linkage mechanism of the high-speed heavy film FFS packaging machine.
