In the prior art, the nails are hung in the gap, and one side of the blocking rod is provided with a telescopic rod with a driving mechanism and a photoelectric sensor. The photoelectric sensor is used to detect the number of nails sliding on the first nail transmission track. When multiple nails slide past the detection laser of the photoelectric sensor in sequence, the photoelectric sensor can count. The photoelectric sensor cooperates with the driving mechanism. When a preset number of nails slide past the photoelectric sensor, the telescopic rod can block the nails.

[0063] The working principle of the automatic heat-sealing and bag-dropping device for material packing provided in this embodiment is as follows:

[0064] Refer to Att Figure 1 to Att Figure 3 , which is the initial state diagram of the device. At this time, the two heat-sealing clamps 3 are opened in a V shape, and the two receiving plates 5 tend to be arranged in a plane, that is, the two receiving plates 5 are in a closed state. As Figure 2 shown, at this time, the claw 22 is lapped on the dial rod 12, and the two support plates 41 are clamped on both sides of the limit plate 11, so that the two vertical rods 42 are in the closest position and can support the two receiving plates 5 to tend to be arranged in a plane.

[0065] In this state, place the material belt on the two receiving plates 5, and the material can be injected into the material belt. In this embodiment, iron nails are injected. The top opening of the material belt is located between the two heat-sealing clamps 3.

[0066] After the material is loaded, the air cylinder 6 drives the rack 61 to extend, driving the gear 21 to move, and at the same time causing the vertical shaft 2 to rotate. See the appendix Figure 4 and the appendix Figure 5 , at this time, the two heat-sealing clamps 3 are combined for heat sealing. It should be noted that in this embodiment, the heat-sealing clamps 3 are energized for heat-sealing control, which is a conventional existing technology here and will not be elaborated further. When the vertical shaft 2 rotates to control the combination of the heat-sealing clamps 3, since the heat-sealing clamps 3 are fixed to the vertical shaft 2, they can be driven. Since the vertical shaft 2 is rotatably connected to the bushing 4 and is restricted by the support plate 41 and the limit plate 11, the bushing 4 will not be driven, so that the claw 22 rotates with the vertical shaft 2, disengages from the lever 12, and finally falls inside the two limit blocks 44, so that when heat-sealing, the two receiving plates 5 still tend to be arranged in a plane and can support the material belt.

[0067] After the heat-sealing is completed, the air cylinder 6 drives the rack 61 to retract, as shown in Figure 6 and Figure 7 , at this time, the state is that the two heat-sealing clamps 3 are in the process of opening. Since the claw 22 falls inside the two limit blocks 44, when the vertical shaft 2 rotates outward, it will drive the limit block 44 to move through the claw 22, and then the support plate 41 will follow and rotate outward. During this rotation process, the lever 12 gradually raises the claw 22, and the tension spring 43 is stretched. Figure 6 and Figure 7 show the moment when the lever 12 raises the claw 22 until it completely disengages from the limit block 44. At this time, since the two vertical rods 42 separate outward, the two receiving plates 5 rotate and droop, that is, the two receiving plates 5 open, causing the heat-sealed material belt to fall. At the same time, since the limit block 44 is disengaged from the driving force of the claw 22, under the pulling of the tension spring 43, the two bushings 4 will be driven to rotate, that is, they will return to the state of Figures 1 to 3 . When the two heat-sealing clamps 3 open in a V shape again, the two vertical rods 42 have been reset, that is, the two receiving plates 5 tend to be arranged in a plane again.

[0068] So far, through one reciprocating action of the air cylinder 6, the actions of heat-sealing and dropping the material belt are completed. In the above operation process, when the two heat-sealing clamps 3 are combined, the two receiving plates 5 do not follow the action. When the two heat-sealing clamps 3 are opening, the two receiving plates 5 complete the two actions of opening and closing.

[0069] The device provided by this embodiment can be placed at the end of the discharge port of the nail-counting device, can also directly heat-seal the loaded material belt, or can also be used for other materials that need to be heat-sealed, and its promotion is relatively common.

[0070] In this specification, the various embodiments are described in a progressive manner. Each embodiment focuses on the differences from other embodiments. For the same and similar parts among the various embodiments, reference can be made to each other. For the device disclosed in the embodiment, since it corresponds to the method disclosed in the embodiment, the description is relatively simple, and for the relevant parts, reference can be made to the description in the method part.

Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to these embodiments shown herein, but will be accorded the widest scope consistent with the principles and novel features disclosed herein.
