DETAILED DESCRIPTION

[0023] The following is a detailed description of the implementation of the utility model in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the utility model, but cannot be used to limit the scope of the utility model. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Combination Figure 1 , Figure 2 and Figure 3 As shown, a film feeding mechanism of a fast clutch packaging machine includes a frame 1, which ensures the stability and durability of the equipment. A reeling mechanism 2 is arranged on the top of the frame 1, which is responsible for storing and orderly releasing the packaging film. The reeling mechanism 2 is used to maintain a constant tension of the packaging film during the conveying process to prevent the film material from being loose or overly tight, which affects the subsequent packaging effect.

[0025] A conveying mechanism 3 is provided below the unwinding mechanism 2. The conveying mechanism 3 includes a first feed roller 31 and a second feed roller 32 horizontally arranged on the frame 1. The packaging film conveyed by the unwinding mechanism 2 enters the gap between the first feed roller 31 and the second feed roller 32 in an unfolded state. The conveying mechanism 3 includes a first feed roller 31 and a second feed roller 32 horizontally arranged on the frame 1. The gap between the two is calculated to ensure that the packaging film can pass smoothly and stably, and will not be damaged or misaligned due to being too tight or too loose. The first feed roller 31 and the second feed roller 32 are usually driven by a motor, and the packaging film is smoothly conveyed through synchronous or asynchronous rotation.

[0026] A quick clutch mechanism 4 for quickly starting and stopping film feeding is arranged on the outer side of the first feeding roller 31. The quick clutch mechanism 4 greatly improves the response speed and flexibility of the packaging machine, so that when it is necessary to quickly replace the packaging film, adjust the film feeding speed or deal with emergencies, the film material feeding can be quickly cut off or restored, thereby effectively improving the production efficiency and the convenience of operation.

[0027] This quick-clutch packaging machine film feeding mechanism not only ensures the stable delivery of the packaging film, but also greatly improves the automation and flexibility of the packaging operation. It is an indispensable and efficient tool in the modern packaging industry.

[0028] Combination Figure 2 , Figure 3 and Figure 4 As shown, the quick clutch mechanism 4 includes a rotating rod 41 arranged outside the first feed roller 31. The rotating rod 41 not only supports the stop block 43, but also controls the start and stop of the first feed roller 31 through the rotation of the rotating rod 41.

[0029] In order to ensure the convenience of operation and the accuracy of control, a control handle 42 is provided at one end of the rotating rod 41. The control handle 42 allows the operator to easily control the clutch state by manual rotation while maintaining the stability and comfort of operation.

[0030] Two stop blocks 43 are arranged on the rotating rod 41, and the two stop blocks 43 are respectively arranged at both ends of the first feeding roller 31. The stop blocks 43 not only enhance the stability of the clutch mechanism, but also ensure that the packaging film is evenly stressed during the conveying process, thereby avoiding film damage or conveying failure caused by uneven stress.

[0031] Combination Figure 2 , Figure 3 and Figure 4 As shown, the stop block 43 is provided with a groove 431 matching the rotation axis of the first feed roller 31. The groove 431 enables the stop block 43 to accurately engage in the rotation axis of the first feed roller 31 when the rotating rod 41 rotates to a certain position, thereby achieving a clutch action. The shape and size of the groove 431 are calculated to match the rotation axis of the first feed roller 31, thereby providing a stable and reliable clutch effect. The groove 431 ensures that when the clutch action occurs, the rotation axis can be quickly and smoothly engaged or released to avoid any impact or delay on the packaging film delivery.

[0032] Combination Figure 1 , Figure 2 and Figure 3 As shown, a film storage lifting roller 33 is provided below the first feed roller 31 and the second feed roller 32. The film storage lifting roller 33 not only enhances the flexibility of the film feeding mechanism, but also ensures the stability and continuity of the packaging film during the feeding process. When the film feeding speed needs to be adjusted or the packaging machine is suspended, the length of the film material can be controlled by the lifting distance of the film storage lifting roller 33 on the frame 1, thereby avoiding the accumulation and waste of the film material.

[0033] The first guide roller 34 and the second guide roller 35 are vertically arranged on the outer side of the film storage lifting roller 33. The main functions of the first guide roller 34 and the second guide roller 35 are to guide and support the packaging film to ensure that it maintains the correct path and tension during the transportation process. The first guide roller 34 is usually located in front of the film storage lifting roller 33, responsible for smoothly guiding the film material from the film storage area to the subsequent processing or packaging link. The second guide roller 35 may be located downstream of the first guide roller 34 to further fine-tune the film material to ensure that it enters the next process in the best state.

[0034] Combination Figure 1 , Figure 2 and Figure 3 As shown, a photoelectric baffle 5 is provided on one side of the first guide roller 34 and the second guide roller 35. The photoelectric baffle 5 is usually composed of one or more opaque baffles. The photoelectric baffle 5 is used in conjunction with a photoelectric sensor. When the packaging film passes through, it blocks or reflects light, thereby triggering the sensor's signal output. The photoelectric baffle 5 enables the control system to monitor the position and movement status of the packaging film in real time. Once abnormal conditions such as film material offset or accumulation are detected, measures can be taken immediately to make adjustments, thereby avoiding waste of film materials and damage to equipment.

[0035] The other side of the first guide roller 34 and the second guide roller 35 is provided with a blocking adjustment mechanism 6. The main function of the blocking adjustment mechanism 6 is to block the packaging film according to the feedback signal of the photoelectric baffle 5 to prevent the packaging film from extending out of the device during transportation. When the photoelectric baffle 5 detects that the film material is offset, the blocking adjustment mechanism 6 can respond quickly and pull the film material back to the correct path; when the film material is detected to be accumulated, it can appropriately slow down or stop the conveying of the film material to avoid malfunctions caused by excessive accumulation.

[0036] Combination Figure 1 , Figure 2 and Figure 3 As shown, the blocking and adjusting mechanism 6 includes a movable rod 61 arranged on the frame 1, and the movable rod 61 ensures its reliability and stability for long-term use. The movable rod 61 ensures that it can cover the film material conveying area between the first guide roller 34 and the second guide roller 35, thereby achieving effective blocking and adjustment of the film material.

[0037] The middle sleeve of the movable rod 61 is provided with a blocking sleeve 62. The main function of the blocking sleeve 62 is to increase the friction between the movable rod 61 and the film material, thereby achieving accurate blocking and adjustment of the film material.

[0038] Combination Figure 1 , Figure 2 and Figure 3As shown, a fixing frame 63 is provided on the blocking sleeve 62, and the fixing frame 63 ensures that it can bear the weight of the control panel 7 and the torque during operation. Its structure is compact and stable, and can be fitted on the blocking sleeve 62 to avoid shaking or displacement during operation. A control panel 7 is installed on the fixing frame 63. The control panel 7 integrates various control buttons, indicator lights, display screens and other components. It allows the operator to easily monitor the working status of the film feeding mechanism, such as the conveying speed, position and tension of the film material. At the same time, the control panel 7 also provides a wealth of control functions, such as start, stop, accelerate, decelerate, fine-tune, etc., so that the operator can accurately control the film feeding mechanism according to actual needs.

[0039] Combination Figure 1 , Figure 2 and Figure 3 As shown, a cantilever 8 is provided on the frame 1, and a coding fine-tuning roller 9 is movably installed on the cantilever 8. In the overall layout of the film feeding mechanism, the frame 1 serves as the basis for supporting and fixing various components, not only focusing on stability and durability, but also fully considering the convenience of operation and the diversity of functions. The setting of the cantilever 8 not only expands the functional area of ​​the frame 1, but also provides a flexible space for the installation of the coding fine-tuning roller 9.

[0040] The cantilever 8 usually extends from one side of the frame 1 to form a cantilever structure. This allows the coding fine-tuning roller 9 to be installed at a position away from the main conveying path, thereby avoiding interference with other components on the main conveying path. The length and angle of the cantilever 8 can be adjusted according to actual needs to adapt to packaging films of different specifications and types.

[0041] The coding fine-tuning roller 9 is movably mounted on the cantilever 8 and can be adjusted up and down, left and right or rotated within a certain range. This flexibility enables the coding fine-tuning roller 9 to be accurately positioned at a designated position on the packaging film, ensuring the accuracy and clarity of the coding information. At the same time, the coding fine-tuning roller 9 can also be adjusted through the corresponding buttons or knobs on the control panel 7, so that the operator can make fine adjustments without interrupting the conveying process, greatly improving work efficiency.

[0042] The present invention is a preferred specific implementation manner, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical scheme and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
