Description

Technical Field

[0001] This utility model relates to the field of tobacco detection technology, specifically to an automatic feeding device for lightweight rod-shaped objects. Background Technology

[0002] On a tobacco production line, it is usually necessary to conduct random inspections of cigarettes produced during production to test conventional parameters such as weight, length, circumference, hardness, ventilation rate, and draw resistance. This allows for the evaluation of the quality of the current batch of cigarettes and ensures stable production quality.

[0003] In previous sampling experiments, staff members would use tools to grab a certain amount of cigarettes and place them into a comprehensive testing platform for sampling. The comprehensive testing platform has a complex structure and a long flow path, requiring staff to feed and test each cigarette one by one.

[0004] To simplify the process or improve the ability of automated testing, a device capable of automatic feeding needs to be designed to accommodate situations where multiple modules are working simultaneously.

[0005] Specifically, analyzing the feeding requirements of cigarette detection reveals that during operation, cigarettes mainly need to enter the detection module vertically from top to bottom. However, cigarette gripping is usually done horizontally. Therefore, a feeding device needs to be designed that can continuously feed cigarettes from a horizontal to a vertical position.

[0006] In order to solve the above problems, people have been seeking an ideal technological solution. Utility Model Content

[0007] The purpose of this invention is to address the shortcomings of existing technologies by providing an automatic feeding device for lightweight rod-shaped objects that can continuously feed materials and switch between horizontal and vertical orientations.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is: an automatic feeding device for lightweight rod-shaped objects, including a hopper, an electric push plate disposed at the bottom of the hopper, and a reversing slide disposed below the hopper;

[0009] The bottom outlet of the hopper is a horizontal outlet and only allows a single rod-shaped object to pass through. The electric push plate is used to push the bottommost rod-shaped object horizontally to the upper inlet of the reversing slide.

[0010] The reversing slide includes an upper inlet, an upper arc-shaped flared slide, a lower vertical slide, and a bottom outlet. One side wall of the upper arc-shaped flared slide is an arc-shaped side wall, and the other side wall is an inclined side wall. The lower vertical slide smoothly transitions with the side wall of the upper arc-shaped flared slide, so that a horizontally entering rod-shaped object can be reversed to a vertical position along the upper arc-shaped flared slide and then enter the lower vertical slide.

[0011] Based on the above, the electric pusher plate is located at the rear end of the hopper, and the electric pusher plate pushes the rod-shaped object forward from the tail end of the bottom outlet of the hopper.

[0012] Based on the above, the electric pusher plate is located on one side of the hopper, and the electric pusher plate pushes out a rod-shaped object from one side of the bottom of the hopper to the other side.

[0013] Based on the above, the width of the upper inlet of the reversing slide is greater than the length of the rod-shaped object.

[0014] Based on the above, a feed detection switch is installed at the lower vertical slide or the bottom outlet.

[0015] Based on the above, it also includes a horizontal track and a drive screw assembly. The hopper, electric push plate, and reversing slide are all mounted on the horizontal slider. The horizontal slider is slidably engaged with the horizontal track, and the drive screw assembly drives the horizontal slider to reciprocate along the horizontal track.

[0016] Based on the above, it also includes a horizontal track and a drive screw assembly. The reversing slide is installed on the horizontal slider, the horizontal slider is slidably engaged with the horizontal track, and the drive screw assembly drives the horizontal slider to reciprocate along the horizontal track. The hopper and the electric push plate are in fixed positions.

[0017] Based on the above, a left fixing plate and a right fixing plate are provided at both ends of the horizontal track, and limit switches are respectively installed on the left fixing plate and the right fixing plate.

[0018] This utility model has substantial features and progress compared to the prior art. Specifically, this utility model combines a hopper structure with a reversing slide to switch a horizontally placed rod-shaped object to a vertically moving rod-shaped object, so that the rod-shaped object can enter the downstream detection module vertically from top to bottom, thus completing the automatic feeding of the rod-shaped object to the detection module.

[0019] Furthermore, the addition of horizontal tracks allows for switching between different testing stations, improving the material feeding efficiency of the testing module. Attached Figure Description

[0025] The technical solution of this utility model will be further described in detail below through specific embodiments.

[0026] Example 1

[0027] like Figure 1 and Figure 2 As shown, an automatic feeding device for lightweight rod-shaped objects includes a hopper 1, an electric push plate 2 disposed at the bottom of the hopper 1, and a reversing slide 3 disposed below the hopper 1.

[0028] The bottom outlet of the hopper 1 is a horizontal outlet and only allows a single rod-shaped object 4 to pass through. The electric push plate 2 is used to push the bottommost rod-shaped object 4 horizontally to the upper inlet of the reversing slide 3.

[0029] The reversing slide 4 includes an upper inlet, an upper arc-shaped flared slide 31, a lower vertical slide 32, and a bottom outlet. One side wall of the upper arc-shaped flared slide 31 is an arc-shaped side wall, and the other side wall is an inclined side wall. The lower vertical slide 32 smoothly transitions to the side wall of the upper arc-shaped flared slide 31, so that the horizontally entering rod-shaped object 4 changes direction to vertical along the upper arc-shaped flared slide and enters the lower vertical slide 32.

[0030] In one embodiment, such as Figure 1 and Figure 2 As shown, the electric push plate 2 is located on one side of the hopper 1, and the electric push plate 2 pushes out the rod-shaped object 4 from one side of the bottom end of the hopper 1 to the other side.

[0031] In another embodiment, such as Figure 3 As shown, the electric push plate 2 is located at the rear end of the hopper 1, and the electric push plate 2 pushes the rod-shaped object 4 forward from the tail end of the bottom outlet of the hopper 1.

[0032] To stably support the rod-shaped object 4, the upper inlet width of the reversing slide 3 is greater than the length of the rod-shaped object 4.

[0033] To prevent the rod-shaped object 4 from blocking the flow and to facilitate counting, a feed detection switch 5 is installed at the lower vertical slide 32 or the bottom outlet.

[0034] Working principle explanation:

[0035] Taking cigarette sticks as an example, cigarette sticks are transported downstream on the cigarette stick conveyor belt of the production line. When sampling inspection is required, a staff member or a special robotic arm will grab a handful of cigarette sticks from the cigarette stick stream and send them into hopper 1. The cigarette sticks are stacked in hopper 1, and the cigarette sticks at the bottom enter the lower outlet of the hopper. Since the lower outlet of the hopper is a horizontal outlet, it cannot be discharged directly and needs to be pushed out with the help of an electric pusher.

[0036] When the detection begins, the electric push plate 2 moves, pushing the lowest cigarette out of the lower outlet. The cigarette falls freely and enters the upper inlet of the reversing slide 3. Due to the presence of the upper arc-shaped flared slide 31, the cigarette cannot maintain its own stability. The arc-shaped sidewall of the cigarette tilts and moves downward. Guided by the arc-shaped sidewall, the cigarette eventually becomes vertical and enters the lower vertical slide 32. The feed detection switch 5 is a photoelectric switch. When the cigarette passes the detection position, the light is blocked, which indicates that a cigarette has passed. This information can be used simply as statistical information or as a trigger signal to trigger the lower detection module to start accepting cigarettes.

[0037] The cigarette then enters the detection module below for testing.

[0038] Example 2

[0039] like Figure 4 As shown, the difference between this embodiment and Embodiment 1 is that it also includes a horizontal track 6 and a drive screw assembly 7. The reversing slide rail 3 is installed on the horizontal slider 8, and the horizontal slider 8 is slidably engaged with the horizontal track 6. The drive screw assembly 7 drives the horizontal slider 8 to reciprocate along the horizontal track 6. The hopper 1 and the electric push plate 2 are fixed in position. A left fixed plate 9 and a right fixed plate 10 are provided at both ends of the horizontal track 6. Limit switches are respectively installed on the left fixed plate 9 and the right fixed plate 10 as trigger reversing switches for the reciprocating movement of the horizontal slider 8.

[0040] In this embodiment, multiple detection modules are arranged in a row below, which can detect multiple cigarettes at the same time. Through the action of the horizontal track 6 and the horizontal slider 8, each cigarette is sent to a different detection module for detection.

[0041] In another embodiment, the hopper, electric push plate, and reversing slide are all mounted on a horizontal slider, the horizontal slider is slidably engaged with a horizontal track, and the drive screw assembly drives the horizontal slider to reciprocate along the horizontal track.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
