With the continuous improvement of production efficiency requirements and the increase in labor costs, the demand for automatic feeding mechanisms is becoming more and more urgent.

[0003] There are many types of feeding mechanisms for packaging machines. For example, Chinese patent CN115402574B discloses a quantitative feeding mechanism for a heat shrink packaging machine, which includes a roller conveyor and other structures. The feeding mechanism of the packaging machine can turn over and convey the material, thereby improving production efficiency and being very convenient. However, the existing feeding mechanisms of packaging machines are often complex in structure, inconvenient to adjust, and lack flexibility when clamping items of different sizes or shapes. In addition, these devices are not adaptable and are difficult to quickly adapt to changes in product specifications on the production line. Therefore, an automatic feeding mechanism for a heat shrink packaging machine is proposed to solve the above problems. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0023] See also Figure 1-3 The utility model provides the following technical solutions: an automatic feeding mechanism of a heat shrink packaging machine, comprising two brackets 1 perpendicular to the bottom surface, a conveyor 2 is fixedly connected to the top of the two brackets 1, a slider 4 is slidably connected to the opposite sides of the inner wall of the conveyor 2, and a loading rack 3 is fixedly connected between the opposite sides of the slider 4.

[0024] It should be noted that in the above embodiment, the conveyor is a roller conveyor, which is a prior art and can be purchased directly, and the loading rack has a large volume and can accommodate larger materials, and the materials are not easy to fall therein, and can be effectively limited by the left and right sides of the loading rack.

[0025] In order to achieve flexible clamping, an adjustable clamping component which can automatically adjust the clamping distance is provided on one side of the loading rack 3.

[0026] Among them, the adjustable clamping assembly includes an outer shell 5, which is arranged on the inner side of the loading rack 3, and the rear side wall bearing of the inner cavity of the outer shell 5 is connected to the first threaded rod 6, and the end of the first threaded rod 6 away from the inner cavity of the outer shell 5 is fixedly connected to the second threaded rod 7, and the end of the second threaded rod 7 away from the first threaded rod 6 is fixedly connected to a hand-turned structure 8 extending to the outside of the outer shell 5, and the outer sides of the first threaded rod 6 and the second threaded rod 7 are both threadedly connected with a threaded sleeve 9, and the top of the threaded sleeve 9 is fixedly connected to an electric push rod 10 with one end extending to the outside of the outer shell 5, and the output end of the electric push rod 10 is fixedly connected to a fixing frame 11, and the left side of the fixing frame 11 is fixedly connected to a clamping plate 12.

[0027] In this embodiment, the hand-turning structure 8 is composed of a rotating rod and a hand-turning wheel, and the front side of the rotating rod is fixedly connected to the hand-turning wheel.

[0028] It can be understood that the adjustable clamping assembly in this embodiment can effectively and automatically control the clamping range, and can also firmly clamp materials of different lengths.

[0029] In addition, the first threaded rod 6 and the second threaded rod 7 have opposite rotation directions. Due to the opposite rotation direction, the threaded sleeve 9 can be displaced to the opposite or opposite side during the engagement process, and the two threaded sleeves 9 will not be displaced in the same direction.

[0030] Among them, a thread groove is opened on the inner side of the threaded sleeve 9, the thread groove on the inner side of the front threaded sleeve 9 is adapted to the thread strip on the outer side of the first threaded rod 6, and the thread groove on the inner side of the rear threaded sleeve 9 is adapted to the thread strip on the outer side of the second threaded rod 7. By opening the thread groove, the threaded rod can be effectively engaged with the threaded sleeve 9.

[0031] In addition, a sliding groove is provided on the inner bottom wall of the outer shell 5, and a limiting slider is fixedly connected to the bottom of the threaded sleeve 9. The sliding groove is adapted to the limiting slider. In this embodiment, the limiting slider and the sliding groove are provided to effectively limit the threaded sleeve 9, thereby avoiding the problem of the threaded sleeve 9 rotating in place.

[0032] In addition, it should be noted that in this embodiment, the clamping plate 12 is a rubber clamping plate, and a strip channel hole is opened on the top of the shell 5, and the strip channel hole is compatible with the electric push rod 10. Since the clamping plate 12 is made of rubber, it can avoid direct rigid contact with the material during the clamping process, preventing material damage.

[0033] The working principle of this embodiment is as follows:

[0034] The material is placed inside the loading rack 3, and then the second threaded rod 7 and the first threaded rod 6 are driven to rotate by turning the hand-turned component 8. At this time, the threaded strip on the outside of the first threaded rod 6 is engaged with the threaded groove inside the front threaded sleeve 9, and the second threaded rod 7 is engaged with the threaded groove inside the rear threaded sleeve 9. The position of the threaded sleeve 9 is limited by setting a limit slider, and the two threaded rods rotate in opposite directions, so that the threaded sleeve 9 can be driven to move to the opposite or opposite side until it is adjusted to a suitable clamping according to the material specifications. Then the electric push rod 10 can be started to drive the fixed frame 11 and the clamping plate 12 to move downward to firmly clamp the material.

[0035] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.
