[0026] In one embodiment, such as Figure 1-9As shown, a blood collection needle tip dispenser includes a feeding tray 1 with a plurality of feeding holes 2 arranged in a circular array. A needle tip dispenser 3 is located in the middle of the upper surface of the feeding tray 1, with the lower surface of the needle tip dispenser 3 aligned with the middle of the feeding tray 1. The needle tip dispenser 3 has a plurality of placement cavities 4 arranged in a circular array, with each placement cavity 4 positioned vertically opposite to one of the feeding holes 2. A connecting shaft 5 is fixedly sleeved at the center of the feeding tray 1. A baffle 6 is fixedly connected to the lower end face of the connecting shaft 5. The upper end face of the baffle 6 is in contact with the lower end face of the feeding tray 1. Several feeding holes 7 are provided on the baffle 6. The feeding holes 7 are arranged in a ring array. The number of feeding holes 2, the placement cavity 4 and the feeding holes 7 are equal. The top of the needle material box 3 is provided with a mounting plate 8. A motor 9 is fixedly connected to the bottom surface of the mounting plate 8. The shaft of the motor 9 is fixedly connected to the upper end face of the connecting shaft 5. Vibrators 10 are fixedly connected to the front and rear sides of the side surface of the feeding tray 1.
[0027] In order to allow the needle in the placement cavity 4 to fall straight down, the placement cavity 4 is composed of a first connecting cavity 41 and a second connecting cavity 42. The first connecting cavity 41 is located on top of the second connecting cavity 42, and the shape of the first connecting cavity 41 is conical.
[0028] In order to block the top of the placement cavity 4 and thus prevent the needle from popping out of the placement cavity 4 during operation, a plug 11 is inserted into the top of each first connecting cavity 41, a pull rod 12 is fixedly connected to the top surface of the plug 11, and a rubber ring 13 is fixedly connected to the side surface of the placement cavity 4.
[0029] In order to allow the lower end of the connecting shaft 5 to pass through the feeding tray 1, a movable hole 14 is provided at the center of the feeding tray 1. The lower end of the surface of the connecting shaft 5 is movably sleeved in the movable hole 14 and extends through to the outside of the bottom of the feeding tray 1.
[0030] To facilitate the installation of the device on the injection molding machine, support legs 15 are fixedly connected to both the left and right sides of the feeding tray 1. The top surfaces of the two support legs 15 are fixedly connected to the left and right sides of the bottom surface of the mounting plate 8, respectively. Mounting seats 16 are fixedly connected to the bottom surfaces of the two support legs 15, and mounting holes 17 are provided on the mounting seats 16.
[0031] In order to prepare needles in advance and to quickly add needles to the placement cavity 4 after the needles in the cavity are used up, connecting rods 18 are fixedly connected to the left and right sides of the bottom surface of the mounting plate 8. The opposing ends of the two connecting rods 18 are fixedly connected to the connecting box 19. The rear side of the bottom surface of the connecting box 19 is in contact with the front side of the upper surface of the feeding tray 1. Several distributing cylinders 20 are placed inside the connecting box 19. The number of distributing cylinders 20 is the same as that of the placement cavity 4. A feeding opening 21 is opened on the rear side of the bottom of the connecting box 19. The feeding opening 21 is vertically opposite to the frontmost placement cavity 4. A connecting opening 22 is opened on the rear side of the left side of the connecting box 19 near the bottom. The connecting opening 22 is connected to the feeding opening 21. A baffle 23 is inserted into the feeding opening 21. The left side of the baffle 23 is movably sleeved in the connecting opening 22 and extends to the outside of the left side of the connecting box 19.
[0032] In order to automatically push the dispensing cylinder 20 to the rear, an electric push rod 24 is movably connected to the middle of the front side of the connecting box 19, and a push plate 25 is fixedly connected to the rear side of the electric push rod 24. The front side of the foremost dispensing cylinder 20 is in contact with the rear side of the push plate 25.
[0033] Working principle: When using this invention, the needle is first placed in the placement cavity 4 on the needle material box 3. The needle in the placement cavity 4 falls into the discharge hole 2 through the second connecting cavity 42. Because the baffle 6 blocks the bottom of the discharge hole 2, the needle cannot be discharged from the bottom of the discharge hole 2. At this time, the motor 9 starts and drives the connecting shaft 5 to rotate. The connecting shaft 5 drives the baffle 6 to rotate. The rotation of the baffle 6 makes the discharge hole 7 and the discharge hole 2 vertically aligned. The needle in the discharge hole 2 falls into the discharge hole 7 and is discharged through the bottom of the discharge hole 7. As the needles fall onto the injection molding machine, the connecting shaft 5 rotates, simultaneously driving the needle holder 3 to rotate as well. This rotation of the needle holder 3 causes the placement cavity 4 to become misaligned with the discharge hole 2, preventing the needles in the placement cavity 4 from falling into the discharge hole 2. Then, when more needles need to be added to the injection molding machine, the motor 9 continues to drive the connecting shaft 5 to rotate. In this way, needles can be automatically added to the injection molding machine without manual placement, improving the device's needle processing efficiency. Workers can pre-place needles into the dispensing cylinder 20. After the needles in the placement chamber 4 are used up, first, pull the lever 12 to remove all the blockages 11 in the placement chamber 4. Then, pull the baffle 23 to the left to remove it from the connecting box 19. At this time, the needles in the last dispensing cylinder 20 pass through the feeding opening 21 and fall into the first placement chamber 4. Then, the first dispensing cylinder 20 is removed from the connecting box 19. Next, the motor 9 drives the needle material box 3 to rotate, causing the adjacent placement chamber 4 to rotate to the feeding opening 21. Directly below, the electric push rod 24 pushes the push plate 25 to move backward, and the push plate 25 pushes the dispensing cylinder 20 to move backward, so that the original second dispensing cylinder 20 on the front and rear sides moves to directly above the feeding opening 21. At this time, the needles in the dispensing cylinder 20 fall into the lower placement cavity 4. Then, in this way, needles can be added to all placement cavities 4, so that after the needles in the placement cavity 4 are used up, needles can be quickly and accurately added to the placement cavity 4, which greatly reduces the time required to add needles and improves the working efficiency of the device.
[0034] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0035] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
