[0002] The three-dimensional transparent film packaging machine is also called a three-dimensional packaging machine or a cigarette packaging machine.

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment 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.

[0021] like Figure 1 and Figure 2 As shown, a feed sensing mechanism of an embodiment of the utility model is applied to a three-dimensional transparent film packaging machine, comprising:

[0022] A feed baffle 1, which is used to be arranged at the feed inlet of the three-dimensional transparent film packaging machine and is connected to the three-dimensional transparent film packaging machine;

[0023] An induction collision block 2, wherein the induction collision block 2 is rotatably connected to the feed baffle 1, and the front side of the induction collision block 2 is tilted upward;

[0024] The feed sensing switch 31 is used to be connected to the lower end surface of the feed baffle 1 and to sense the movement of the sensing block 2.

[0025] In this embodiment, by setting the feed baffle 1 and the sensing bumper 2, when the feed moves onto the feed baffle 1, the feed can act on the sensing bumper 2, and by utilizing the weight of the feed itself, the feed can drive the upwardly inclined front side of the sensing bumper 2 to move downward, and the feed sensing switch 31 is used to sense the sensing bumper 2, so the feed sensing switch 31 can sense the movement of the sensing bumper 2, thereby determining that it is the feed rather than the empty box that moves onto the feed baffle 1, which is convenient for the three-dimensional transparent film packaging machine to package the feed; conversely, when the empty box moves onto the feed baffle 1, the empty box acts on the sensing bumper 2, and the weight of the empty box is lighter than that of the feed, and it cannot drive the upwardly inclined side of the sensing bumper 2 to move downward, so the feed sensing switch 31 cannot sense the movement of the sensing bumper 2, which can prevent the three-dimensional transparent film packaging machine from packaging the empty box. Therefore, by setting the feed baffle 1, the induction bumper 2 and the feed induction switch 31, the difference in weight between the feed and the empty box can be used to distinguish the feed and the empty box, so that the three-dimensional transparent film packaging machine can accurately package the feed and avoid the empty box detection from passing.

[0026] Alternatively, if Figure 2As shown, the feed sensing mechanism also includes a collision block seat 41 and a collision block shaft 42. A mounting hole 11 is opened in the middle of the feed baffle 1. The two collision block seats 41 are respectively located on the left and right sides of the mounting hole 11, and are both connected to the lower end bolts of the feed baffle 1. The two ends of the collision block shaft 42 are respectively rotatably connected to the two collision block seats 41. The rear side of the sensing collision block 2 is connected to the collision block shaft 42. The front side of the sensing collision block 2 passes through the mounting hole 11 and is located above the feed baffle 1. The center of gravity of the sensing collision block 2 is close to the lower end of the sensing collision block 2.

[0027] In this embodiment, by providing a collision block seat 41 and a collision block shaft 42 on the lower end surface of the feed baffle 1, and the collision block shaft 42 is provided between the two collision block seats 41, a stable connection can be established between the collision block shaft 42 and the feed baffle 1. At the same time, the two collision block seats 41 are both connected to the lower end bolts of the feed baffle 1, so that the collision block seats 41 can be easily installed and removed. In addition, a mounting hole 11 is provided in the middle of the feed baffle 1, so that the rear side of the induction collision block 2 is connected to the collision block shaft 42 located below the feed baffle 1, and the front side of the induction collision block 2 passes through the mounting hole 11 and is located above the feed baffle 1, and the center of gravity of the induction collision block 2 is close to the lower end of the induction collision block 2, so that the front side of the induction collision block 2 is easily tilted upward, which is beneficial for the feeding to act on the front side of the induction collision block 2.

[0028] Alternatively, if Figure 1 and Figure 2 As shown, the induction collision block 2 includes a first connecting plate 21, a second connecting plate 22 and a third connecting plate 23. The first connecting plate 21, the second connecting plate 22 and the third connecting plate 23 are connected end to end in sequence to form an L-shaped structure. The first connecting plate 21 is bolted to the middle part of the collision block shaft 42, and the front side of the third connecting plate 23 passes through the mounting hole 11 and is located above the feed baffle 1.

[0029] In this embodiment, the sensing collision block 2 is set to a structure including a first connecting piece 21, a second connecting piece 22 and a third connecting piece 23, and the first connecting piece 21, the second connecting piece 22 and the third connecting piece 23 are connected end to end in sequence to form an L-shaped structure, and the rear side of the third connecting piece 23 is connected to the second connecting piece 22 and the third connecting piece 23 in sequence. Then, the center of gravity of the L-shaped structure is located on the rear side of the L-shaped structure, and the front side of the third connecting piece 23 can be tilted upward.

[0030] Alternatively, if Figure 2 As shown, a mounting groove 421 is formed in the middle of the collision block shaft 42 , and a side surface of the first connecting piece 21 is in contact with the bottom surface of the mounting groove 421 .

[0031] In this embodiment, a mounting groove 421 is opened in the middle of the impact block shaft 42, and one side surface of the first connecting plate 21 is fitted with the bottom surface of the mounting groove 421, so that the bolt can pass through the first connecting plate 21 and the bottom surface of the mounting groove 421 in turn, which is helpful to simplify the installation process of the first connecting plate 21 and the bolt, thereby facilitating the connection between the first connecting plate 21 and the impact block shaft 42.

[0032] Alternatively, if Figure 2 As shown, the feed sensing mechanism further includes a feed sensing switch seat 32 , the feed sensing switch seat 32 is connected to the lower end surface of the feed baffle 1 , and the feed sensing switch 31 is bolted to the feed sensing switch seat 32 .

[0033] In this embodiment, the feed sensing switch 31 is difficult to be directly connected to the feed baffle 1 due to its own structural problems. By setting the feed sensing switch seat 32, the feed sensing switch 31 can be assembled and connected with the feed sensing switch seat 32 first, and then the feed sensing switch seat 32 can be assembled and connected with the feed baffle 1, which is conducive to assembling the feed sensing switch 31 with the feed baffle 1.

[0034] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
