[0026] The present invention provides a strip-shaped parts feeding device. To make the purpose, technical solution and effect of the present invention clearer and more specific, the present invention is further described in detail below. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0027] See also Figures 1 to 6 The present utility model provides a strip-shaped parts feeding device. The accompanying drawings are only used to explain the structural principles and are not proportional to the actual product. The accompanying drawings only depict structures related to the invention of this application, and some conventional structures are not specifically depicted. The terms "first", "second", etc. described herein are merely different names for similar structures for the purpose of explanation, and are not intended to limit this application. The "several" described herein refers to an indefinite number, because the number of structures referred to is not an invention point, and therefore is not specifically limited.

[0028] In order to observe the internal structure, Figure 1 and Figure 2 The protective housing of the strip parts feeding device is not shown; Figure 6 The cover above the chute is not shown.

[0029] The strip parts feeding device includes a frame 8, on which a loading unit 1, a feeding unit and a discharging unit 3 are arranged; the loading unit includes a hopper 10 and a rotary loading mechanism, and the feeding unit includes an inclined trough 21 and a vibrator (not shown in the figure); the trough inlet end ( Figure 4 The right end of the trough is higher than the outlet end of the trough ( Figure 4 The left end of the blanking unit is provided with a sensor 39 for counting the strip parts (such as Figure 6 shown).

[0030] Because the trough is tilted and the vibrator is used to vibrate the trough, the strip-shaped parts in the hopper can be sequentially moved from the inlet end to the outlet end of the trough. The type of vibrator is not specifically limited here, as long as it can vibrate the trough and cause the strip-shaped parts to move forward in the trough.

[0031] like Figure 1 and Figure 3 As shown, the rotary feeding mechanism includes a tray 12 and a first driving device 11 for driving the tray to rotate. The tray is provided with a plurality of blades 121 facing inward; the tray is located at the inlet end of the trough (i.e., some blades of the tray are located above the inlet end of the trough). The tray is rotatably connected to the frame. The first driving device is preferably a motor that drives the tray to rotate through gear transmission or other means. The tray is connected to the hopper. After the strip parts are poured into the hopper, they will enter the bottom of the tray (such as Figure 4As the tray rotates, the strip parts are brought to a higher position until they fall (e.g. Figure 4 As shown in the figure, assuming counterclockwise rotation, the strip parts will fall down when they are brought to area B. Some of the strip parts will fall into the inlet of the trough, and the strip parts that do not fall into the trough will fall into the hopper and then enter the tray. This reciprocating process continuously causes strip parts to fall into the inlet of the trough, realizing automatic loading.

[0032] In actual application, it is possible that too many strip parts are accumulated at the inlet end of the trough. In order to solve this technical problem, the following settings can be further made: Figure 2 and Figure 5 As shown, the strip parts feeding device is further provided with a sweeping mechanism; the sweeping mechanism includes a sweeping plate 48 rotatably connected to the frame, and a second driving device 41 for driving the sweeping plate to rotate.

[0033] The second driving device 41 is preferably a motor, which drives a push rod 43 to reciprocate in the vertical direction through a cam 42; the top end of the push rod is connected to one end of a lever 44 (the lever is rotatably connected to the frame), and the other end of the lever is provided with a driving gear 45 ( Figure 5 The driving gear is a sector gear, but is not limited thereto. A sweeping plate 48 is connected to the frame via a rotating shaft 47. A driven gear 45 is disposed at one end of the rotating shaft and meshes with the driving gear. During operation, the motor drives the lever to swing via a push rod, which in turn drives the sweeping plate to rotate via a gear transmission, thereby sweeping away excess strip-shaped parts at the inlet of the trough.

[0034] Further, a brush 49 is provided at the bottom of the sweeping plate 48. By arranging the brush, it is possible to sweep the material more conveniently without causing a rigid collision with the trough.

[0035] like Figure 4 As shown, preferably, two receiving plates 22 are provided at the inlet end of the trough 21. The two receiving plates are arranged obliquely so that the strip-shaped parts falling from the tray can smoothly reach the inlet end of the trough.

[0036] like Figure 2 and Figure 6 As shown, the discharge unit includes a chute 33, a slider 32 and a slider driving cylinder 31; the outlet end of the chute corresponding to the feed trough is provided with a feed port ( Figure 6 The position corresponding to the middle strip part 91), the slide is provided with an air nozzle 34 and a discharge pipe 35; the slide is provided with a receiving trough ( Figure 6The position corresponding to the strip-shaped part 92 in the middle). In actual use, the air nozzle is connected to the compressed air source in the workshop. After the strip-shaped part enters the receiving trough of the slider from the feeding port, the slider drives the cylinder to move the slider so that the receiving trough is located between the air nozzle and the discharge port. The compressed air blows the strip-shaped part out of the discharge port, and then the slider drives the cylinder to reset the slider (at this time, the receiving trough is aligned with the feeding port and returns to the original position). Figure 6 status).

[0037] For ease of understanding, Figure 6 The figure schematically shows two strips 91 and 92. 92 represents the strip that has entered the chute on the slider, while 91 represents the strip that has just left the chute outlet and entered the feed port on the chute. Strip 91 is in a waiting state. When the slider moves forward to deliver strip 92 to the air nozzle, strip 91 abuts against the side wall of the slider, so the strip is still in a waiting state. When the slider is reset (i.e., back to the original position), Figure 6 ), the strip part 91 is pressed by the strip parts behind it into the receiving trough of the slider (that is, the vibrator vibrates the trough, causing the strip parts in the trough to move forward one by one), and becomes a new strip part 92. This reciprocating cycle continues, and the strip parts are fed into the receiving trough of the slider one by one, and then blown away by the compressed air at the air nozzle and discharged from the discharge pipe.

[0038] like Figure 6 As shown, the sensors used to count the strip-shaped parts are two photoelectric sensors 39, positioned opposite each other on the discharge pipe. As the strip-shaped parts are blown out of the discharge port and into the discharge pipe at a relatively high speed, the two opposing photoelectric sensors accurately detect the strip-shaped parts, ensuring accurate counting. In practice, the discharge pipe is connected to a hose (not shown), the outlet end of which is connected to a packaging bag (not shown), allowing the strip-shaped parts to be blown into the bag.

[0039] For ease of understanding, the working principle is briefly described below: (1) Strip parts are poured into the hopper, and the rotary loading mechanism feeds the strip parts into the trough; (2) Under the action of the vibrator, the strip parts move from the inlet end of the trough to the outlet end of the trough; (3) The strip parts at the outlet end of the trough enter the receiving trough of the slider through the feed port on the side wall of the slide; (4) The slider drives the cylinder to push the slider forward, and the strip parts in the receiving trough are located between the air nozzle and the discharge port; (5) The compressed air from the air nozzle blows the strip parts in the receiving trough out of the discharge port, and the slider drives the cylinder to reset the slider; (6) The strip parts are blown out from the discharge pipe and finally blown into the packaging bag. During this process, two photoelectric sensors detect the strip parts and count them.

[0040] From the above analysis, it can be seen that the strip parts feeding device provided by the utility model can realize automatic feeding and counting of strip parts (or similar parts), thereby improving production efficiency and avoiding the counting problem that is prone to errors caused by manual counting.

[0041] It is understandable that those skilled in the art can make equivalent substitutions or changes based on the technical solution and the utility model concept of the present invention, and all these changes or substitutions should fall within the scope of protection of the present invention.
