[0032] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0033] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly attached to the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation methods.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which this invention pertains. The terms used in this specification are for the purpose of describing specific embodiments only and are not intended to limit this invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0035] like Figures 1 to 9 The drum type nail feeding machine shown in FIG. 11 includes a feeding mechanism 1, a linear conveying mechanism 2, a screening mechanism 3 and a distribution mechanism 4. Figure 1 As shown in:

[0036] The feeding mechanism 1 includes a rotatable roller 11 and a rolling drive member 12 for driving the roller 11 to rotate; the roller 11 drive member here has various structural forms, which can be as follows Figure 1 As shown in the figure, rollers are used to support the rolling of the drum 11, and the rolling of the drum 11 is driven by rotating the driving roller. Those skilled in the art can also drive it by directly using a motor or using a sprocket chain.

[0037] The linear conveying mechanism 2 has at least two parallel linear channels 21, one end of which extends into the drum 11; it should be pointed out here that in the embodiment of the present invention, the linear channel 21 is arranged at an angle and tilted downward toward the outlet. In this way, the screws can fall by their own gravity; by adopting the linear channel 21, the reliability of transportation can be guaranteed.

[0038] The screening mechanism 3 is arranged above the straight material channel 21, and is used to brush the screws that have not entered the material channel into the drum 11; it should be pointed out here that in the embodiment of the present utility model, the screening mechanism 3 has various forms. For example, it can be vertically blowing toward the top of the straight material channel 21, and the screws that fall on the straight material channel 21 are blown into the drum 11 by high-pressure gas. It can also be achieved by using the brush structure form described below.

[0039] The distribution mechanism 4 includes a distribution assembly 41 that interfaces with the other end of the linear channel 21 and a channel assembly 42 connected to the distribution assembly 41. The channel assembly 42 includes discharge ports 42a, twice the number of the linear channel 21. The provision of multiple discharge ports 42a and the distribution assembly 41 provides more options for screw feeding.

[0040] In the above embodiment, the screws are scattered onto the linear conveying mechanism 2 through the loading mechanism 1. By setting the linear conveying mechanism 2 to have at least two, the two linear material channels 21 are used to convey the screws, and the discharge port 42a in the distribution mechanism 4 is set to twice the number of linear material channels 21, so that the number of output lines of the screws can be selected as needed, which improves the output efficiency of the nail supply compared with the existing technology.

[0041] Alternatively, as Figure 2 As shown in FIG, the drum 11 is tilted, and the open end of the drum 11 is tilted upward. In addition, in the embodiment of the present invention, the bottom inner wall of the drum 11 is provided with a prying piece 11a perpendicular to the bottom, and a plurality of prying pieces 11a are evenly arranged along the circumferential direction. By tilting the drum 11, the screws in the drum 11 can be moved toward the bottom of the drum 11 under the action of gravity, as shown in FIG. Figure 2 As shown in , when the material-pickup piece 11a rotates with the roller 11, the screw in the roller 11 can be lifted until the angle of the material-pickup piece 11a causes the screw to slide off again. In an embodiment of the present invention, the straight material channel 21 is arranged at the position where the screw slides off the material-pickup piece 11a.

[0042] In the embodiment of the present utility model, as Figure 3 and Figure 4 As shown in FIG, the linear material channel 21 includes two parallel vertical plates 21a spaced apart. The spacing between the vertical plates 21a is greater than the diameter of the screw stud and less than the diameter of the screw nut, allowing the screw to be vertically arranged and moved between the vertical plates 21a. To improve the reliability of screw movement, in the embodiment of the present utility model, the spacing between the vertical plates 21a is slightly greater than the diameter of the screw to reduce the risk of the screw getting stuck during movement.

[0043] Please continue to refer to Figure 4To reduce the risk of the screw skewing due to vertical movement during movement, in this embodiment of the present invention, the discharge end of the linear channel 21 further includes a pressure plate 21b. This pressure plate 21b is positioned atop the two vertical plates 21a, with the distance between the pressure plate 21b and the tops of the vertical plates 21a being no less than the thickness of the screw nut. Similarly, in this embodiment of the present invention, the distance between the pressure plate 21b and the tops of the vertical plates 21a is slightly greater than the thickness of the nut, thereby reducing the risk of the screw snagging during movement.

[0044] In some embodiments of the present invention, to further improve feeding efficiency, the end of the linear channel 21 that extends into the drum 11 is further provided with a connecting piece 21c. The connecting piece 21c has a V-shaped cross-section and a V-shaped opening 21c1 at the end away from the drum 11. The V-shaped opening 21c1 corresponds to the gap between the two vertical plates 21a. The provision of the connecting piece 21c increases the receiving area of ​​the linear channel 21. The provision of the V-shaped opening 21c1 at the end facilitates the stud portion of the screw to enter the linear channel 21 first, thereby further improving the reliability of the screw entering the linear channel 21.

[0045] In some embodiments of the present invention, Figure 5 As shown in FIG, the screening mechanism 3 includes an eccentric rotary driver 31 and a brush 32 connected to the driving end of the eccentric rotary driver 31. The eccentric rotary driver 31 drives the brush 32 to reciprocate in a direction perpendicular to the linear material channel 21, and the vertical projection of the brush 32 is inside the drum 11. By the brush 32 brushing left and right on the top of the linear material channel 21, screws on the linear material channel 21 that are not correctly inserted into the material channel can be brushed off, thereby improving the smoothness of feeding.

[0046] like Figure 3 As shown in the figure, in the embodiment of the present invention, the screening mechanism 3 further includes a full material detection sensor 33 arranged toward the linear material channel 21. It should be noted here that there are various types of sensors for detecting whether the linear material channel 21 is full of screws. For example, it can be a laser sensor that emits laser light to detect whether it is blocked by the screws. If blocked, it means that the material is full. If not blocked, the laser signal can be received at the receiving end. Of course, those skilled in the art can also choose other forms according to needs.

[0047] Alternatively, as Figure 7 and Figure 8As shown in , the material distribution assembly 41 includes a laterally movable material distribution block 41a and a material distribution drive 41b connected to the material distribution block 41a. The material distribution block 41a has a blanking hole 41a1 corresponding to the linear material channel 21. The material channel assembly 42 includes a laterally movable switching seat 42b and a material channel switching drive 42c connected to the switching seat 42b. The discharge port 42a is set on the switching seat 42b. The material distribution drive 41b and the material channel switching drive 42c here can be equipped with a cylinder. The blanking holes 41a1 correspond to the linear material channel 21 here, which means that the spacing between the multiple blanking holes 41a1 is the same as that of the linear material channel 21, so that screws of multiple linear material channels 21 can be connected simultaneously.

[0048] In order to realize that the screw follows the movement of the dividing block 41a during the movement of the dividing block 41a, the screw falls when the dividing block 41a moves to the corresponding drop hole 41a1. Figure 8 and Figure 9 As shown in FIG, the dividing block 41a also has a screw release plate 41c movably arranged toward the blanking hole 41a1 and a release drive 41d connected to the screw release plate 41c. The screw release plate 41c has a socket 41c1 for overlapping screws. The release drive 41d is used to drive the screw release plate 41c to move toward or away from the blanking hole 41a1. Please refer to FIG. Figure 9 , the socket 41c1 is U-shaped and faces the direction of the straight material channel 21, and the width of the socket 41c1 is close to the straight material channel 21, so that the screw can be hung on the socket 41c1; in an embodiment of the present invention, the release drive 41d can be a cylinder. When the cylinder moves toward the drop hole 41a1, it can prevent the screw from falling further. At this time, the dividing block 41a can be moved to select the required discharge port 42a; when it moves to the corresponding position, the release drive 41d drives the screw release plate 41c in reverse, so that the screw moves out of the socket 41c1 and falls into the drop hole 41a1 and then enters the discharge port 42a; in an embodiment of the present invention, the outlet material is connected to the pipeline to realize the delivery of the screw to the required position.

[0049] Those skilled in the art should understand that the present invention is not limited to the above-described embodiments. The above-described embodiments and the specification are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention.
