[0026] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0027] In order to solve the problems of low efficiency and poor processing quality of existing tobacco strip beautification devices, the present invention provides a tobacco strip pack four-sided film horizontal feeding device, which has good film processing quality and high efficiency. In order to further illustrate the structure of the present invention, the detailed description is as follows in conjunction with the drawings:

[0028] See also Figure 1-Figure 3 A tobacco strip package four-sided film hot stamping horizontal feeding device includes a frame 1. The frame is a frame box composed of a rigid profile frame and a rigid plate body with supporting and protecting functions. The shape is not limited, and it can be designed and assembled according to the outer contour of the device and the working position of the components to complete the function.

[0029] It also includes two side cigarette racks 2, a pack feeding drive unit, a side hot stamping drive unit, a side soldering iron plate 3, an upper soldering iron plate 4, a lower soldering iron plate 5, an upper hot stamping drive unit, and a lower hot stamping drive unit.

[0030] The side cigarette holder is a rigid frame extending horizontally and longitudinally. The two side cigarette holders are arranged horizontally and symmetrically. There is a strip package translation hot stamping film channel between the two side cigarette holders. The extension direction of the strip package translation hot stamping film channel is parallel to the longitudinal extension direction of the side cigarette holder, and the width of the strip package translation hot stamping film channel is greater than the length of the strip package.

[0031] The strip pack feeding drive unit is installed on the frame, and the strip pack feeding drive unit drives the side cigarette pushing bracket to move horizontally, and the direction of the horizontal feeding movement is parallel to the extension direction of the strip pack translation hot foil channel. Existing known equipment has a variety of optional component units that meet the functional requirements of the strip pack feeding drive unit, such as linear modules and cylinders. The installation method of the linear module and the cylinder and the working principle of the horizontal feeding and moving feeding of the driving components are conventional technologies in the mechanical field. The strip pack feeding drive unit drives the side cigarette pushing bracket to move horizontally and reciprocatingly in a direction parallel to the extension direction of the translation hot foil channel, thereby realizing the feeding action and the action of clamping and releasing cigarettes.

[0032] The side film-stamping drive unit is installed on the frame, and the side film-stamping drive unit drives the side cigarette holder to move horizontally and horizontally, and the direction of the horizontal side film-stamping movement is perpendicular to the extension direction of the strip package translation film-stamping channel. There are many optional component units in the existing known equipment that meet the functional requirements of the side film-stamping drive unit, such as linear modules and cylinders. The installation method of the linear module and the cylinder and the working principle of the horizontal feeding and moving of the driving components are conventional technologies in the mechanical field. The side film-stamping drive unit drives the side cigarette holder to move horizontally and reciprocatingly in a direction perpendicular to the extension direction of the translation film-stamping channel, thereby driving the side film-stamping.

[0033] The combined motion track of the strip feeding drive unit and the side foil stamping drive unit is a zigzag curve on the horizontal plane. This motion track is the working basis for clamping and feeding the strips and foil stamping the side end surfaces of the strips.

[0034] The soldering iron plate is a known component in a traditional strip packing container. It is a flat plate and its size can be designed according to work needs.

[0035] The side ironing plates are installed on the inner side of the side cigarette holder and are evenly distributed along the extension direction of the film-hot stamping channel for the strip package. The two symmetrical side ironing plates are used to press the end faces of the strip package. That is, the left-right symmetrical side ironing plates installed on the side cigarette holder constitute a set of side ironing components for pressing the transparent film at the ends of the strip package. In the extension direction of the film-hot stamping channel for the strip package, multiple such side ironing components are distributed at the same interval. In addition to pressing the ends of the strip package, each set of side ironing components also plays the role of clamping the strip package. When the strip package is clamped, the strip package is driven by the movable side cigarette holder to move forward intermittently to achieve feeding.

[0036] The upper soldering iron plate is arranged between the two side cigarette holders and above the strip package translation hot stamping film channel, and is used to press the upper end surface of the strip package; the lower soldering iron plate is arranged between the two side cigarette holders and below the strip package translation hot stamping film channel, and is used to press the lower end surface of the strip package. The upper and lower soldering iron plates clamp up and down to press the upper and lower end surfaces of the strip package, and support the strip package during the interval when the side soldering iron plates release the strip package.

[0037] The upper film-stamping driving unit is installed on the frame, and drives the upper soldering iron plate to move vertically; the lower film-stamping driving unit is installed on the frame, and drives the lower soldering iron plate to move vertically.

[0038] The working requirement of the upper and lower hot film driving units is to be able to drive the upper and lower soldering iron plates to move vertically and linearly. There are many optional component units with this driving function in the existing known equipment, and the most common ones are also linear modules and cylinders. The installation method of the linear module and the cylinder and the working principle of the horizontal feeding and moving of the driving components are conventional technologies in the mechanical field. The pack feeding driving unit drives the side cigarette moving bracket to move horizontally and reciprocatingly in a direction parallel to the extension direction of the translational hot film channel, thereby realizing the feeding action and the action of clamping and releasing cigarettes.

[0039] In the present embodiment, although the strip pack feeding drive unit, the side hot stamping film drive unit, the upper hot stamping film drive unit and the lower hot stamping film drive unit can all use standard components such as linear modules or cylinders, in order to improve the motion coordination performance and working stability of the device, in the present embodiment, the structure of the feeding drive unit, the side hot stamping film drive unit, the upper hot stamping film drive unit and the lower hot stamping film drive unit is newly designed.

The side pressure drive rod is in the shape of a shaft rod, and can be extended and retracted to both sides of the frame under the guidance of the shaft sleeve. The spatial curve design of the circumferential groove of the side pressure cylindrical cam determines the extension and retraction frequency and stroke of the side pressure drive rod. The combination of the cylindrical cam and the roller is a conventional matching technology in the mechanical field. The side pressure live frame is installed at the outer end of the side pressure driving rod. Specifically, the side pressure live frame is a frame body carrying the side cigarette holder, and its lower part is provided with a C-shaped holding hole and a locking bolt for holding the outer end of the side pressure driving rod.
