Description

Technical Field

[0001] This utility model relates to the field of film tensioning device technology, and in particular to a film tensioning device for an intelligent packaging machine. Background Technology

[0002] Stretch film packaging machines, also known as stretch film vacuum packaging machines or laminating machines, are a type of packaging equipment with a high degree of automation. Their main function is to stretch the lower film into shape as required, then put the packaged goods into the formed lower film cavity, then vacuum or vacuum-fill the packaged goods in the sealing box, and finally heat-seal the upper and lower films in the sealing box, and then divide the packaged goods by cross-cutting and longitudinal cutting.

[0003] The film tensioning device of a food packaging machine is a key component of a stretch film packaging machine, used to ensure that the film maintains appropriate tension and stability during the packaging process;

[0004] Existing film tensioning devices typically achieve film tensioning through the gravity of the tensioning roller. However, the tension force on the film is difficult to adjust, and using the same tension for different types of food affects the stability of the packaging. Therefore, this invention proposes a film tensioning device for an intelligent packaging machine to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the inconvenience in adjusting the tension force on the tension film, the use of the same tension for different types of food, and the impact on packaging stability. Therefore, this invention proposes a film tensioning device for an intelligent packaging machine.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A film tensioning device for an intelligent packaging machine includes a support frame and multiple guide rollers, wherein the guide rollers are rotatably connected to the inner side of the support frame. The film tensioning device also includes...

[0008] An adjustment mechanism and an unlocking mechanism, wherein the adjustment mechanism cooperates with the unlocking mechanism and the bracket, respectively;

[0009] The tensioning mechanism includes: a sliding frame and two tensioning rollers;

[0010] The sliding frame is slidably connected to the inside of the support, and the tension roller is rotatably connected to the sliding frame.

[0011] As a preferred embodiment of this utility model, the adjustment mechanism includes: a mating frame, a driving frame, a fixing frame, and a handle;

[0012] The mating frame is fixedly installed on the top of the sliding frame, the driving frame is slidably connected to the inside of the fixed frame, the fixed frame is fixedly installed on the inside of the bracket, and the handle is fixedly installed on the top of the driving frame.

[0013] Furthermore, the adjustment mechanism includes a cooperating frame that fixes the top of the sliding frame, a drive frame that slides and connects to the inner side of the fixed frame, a fixed frame that fixes the inner side of the support, a handle that fixes the top of the drive frame, and an operating handle that moves the drive frame. By squeezing the sliding frame with the cooperating frame to raise and lower, the position of the tension roller can be precisely adjusted, thereby controlling the film tension and adapting to different packaging needs.

[0014] As a preferred embodiment of this utility model, the unlocking mechanism includes: a mating rod, a rotating frame, and a control rod;

[0015] The mating rod is fixedly installed on the top of the fixed frame, the rotating frame is rotatably connected to the inside of the handle, the mating block is fixedly installed on the rotating frame, and the control rod is fixedly installed on the top of the rotating frame.

[0016] Furthermore, the unlocking mechanism includes a mating rod fixing the top of the fixed frame, a rotating frame rotatingly connecting the inside of the handle, a mating block fixing the rotating frame, and a control rod fixing the top of the rotating frame. Operating the control rod drives the rotating frame to rotate, causing the mating block to disengage from the mating rod blocking groove, releasing the lock on the drive frame, thus adjusting the tension. After loosening, the torsion spring automatically resets the mating block and locks it into the blocking groove locking position, ensuring stable tension.

[0017] As a preferred embodiment of this utility model, the inner side of the bracket is provided with symmetrically arranged vertical sliding grooves, and the left and right sides of the sliding frame are slidably connected to the inner walls of the two vertical sliding grooves respectively.

[0018] Furthermore, a vertical groove is provided on the inner side of the support to allow the sliding frame to slide left and right, providing precise guidance for the lifting and lowering of the sliding frame and ensuring smooth adjustment of the tension roller position.

[0019] As a preferred embodiment of this utility model, torsion springs are fixedly installed on both the left and right sides of the rotating frame, and the torsion springs are fixedly connected to the handle.

[0020] Furthermore, the rotating frame is equipped with a torsion spring connecting handle. The torsion spring provides restoring force, which automatically drives the rotating frame to rotate after the unlocking operation, causing the mating block to engage in the blocking groove and lock, thus maintaining stable tension.

[0021] As a preferred embodiment of this utility model, a round rod is fixedly installed at the bottom of the drive frame, and the outer side of the round rod slides in contact with the inner wall of the mating frame.

[0022] Furthermore, the fixed round rod at the bottom of the drive frame slides into contact with the inner wall of the mating frame, and the round rod effectively transmits the movement of the drive frame to the mating frame, ensuring that the tension adjustment action is accurate and reliable.

[0023] As a preferred embodiment of this utility model, the top of the mating rod is provided with equally spaced blocking grooves, and a mating block is fixedly installed on the front side of the rotating frame, with the outer side of the mating block sliding in contact with the inner wall of the blocking groove.

[0024] Furthermore, the top of the mating rod has equidistant blocking grooves that slide in contact with the mating block on the rotating frame. The mating block can reliably engage with the selected blocking groove, providing multiple stable locking positions for the tension roller to adapt to different tension requirements.

[0026] 2. The unlocking mechanism includes a mating rod fixing the top of the fixed frame, a rotating frame rotating and connecting the inside of the handle, a mating block fixing the rotating frame, and a control rod fixing the top of the rotating frame. Operating the control rod drives the rotating frame to rotate, causing the mating block to disengage from the mating rod blocking groove, releasing the lock on the drive frame, and thus adjusting the tension. After releasing, the torsion spring automatically resets the mating block and locks it into the blocking groove locking position, ensuring stable tension.

[0027] In this invention, a tensioning mechanism is provided, which includes a sliding frame that is slidably connected to the inner side of the support.

This solves the problem of non-adjustable tension in traditional gravity tensioning methods.

Simply push the control rod 13 on the handle 9, and the control rod 13 will cause the rotating frame 10 to disengage from the cooperating rod 8. First, unlock the driving frame 6, and then push the driving frame 6 to move horizontally, so that the driving frame 6 can be raised and lowered by squeezing the sliding frame 3 through the round rod, thereby achieving precise adjustment of the position of the tensioning rollers 4, thereby controlling the film tension and adapting to different packaging needs. This solves the problem of non-adjustable tension in the traditional gravity tensioning method. The adjustment mechanism and unlocking mechanism, together with the bracket 1, facilitate precise control of tension according to the needs of different packaging materials, improving packaging stability. After adjustment, release the rotating frame 10. After release, the torsion spring 11 will automatically reset the cooperating block 12 and lock it into the blocking groove to ensure stable tension.
