DETAILED DESCRIPTION

[0023] The technical solution of this utility model will now be clearly and completely described in conjunction with the accompanying drawings. In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0024] The present invention will be further described below with reference to the accompanying drawings.

[0025] like Figures 1-8 As shown, a screw conveyor bottle neck clamping mechanism includes a bottle hanging guardrail 1, a conveying screw 2, a bottle blocking guardrail 3, a guardrail mounting assembly, a screw mounting assembly, and a bottle blocking guardrail mounting assembly;

[0026] Specifically, the bottle hanging guardrail 1 is installed on the guardrail mounting assembly, the conveying screw 2 is installed on the screw mounting assembly, and the bottle blocking guardrail 3 is installed on the bottle blocking guardrail mounting assembly. The conveying screw 2 is located on the lower left side of the bottle hanging guardrail 1, and the bottle blocking guardrail 3 is located on the lower right side of the bottle hanging guardrail 1. The medicine bottle 4 slides on the bottle hanging guardrail 1, with its lower end located in the groove of the conveying screw 2 and its side wall in contact with the bottle blocking guardrail 3. The lower end of the bottle hanging guardrail 1 has a T-shaped groove 13 for engaging the neck of the medicine bottle 4.

[0027] This screw conveyor bottle neck clamping mechanism has a simple structure and can prevent scratches. During bottle transfer, the bottom guide rail is eliminated, and a bottle hanging guard works in conjunction with the screw for discharging, thus solving the problem of scratches on the bottle surface caused by friction between the bottom of the medicine bottle and the bottom guide rail.

[0028] Specifically, the guardrail installation assembly includes a bottle hanging mold mounting frame 5, two bottle hanging support rods 6, and a bottle hanging mold mounting plate 7; the side wall of the bottle hanging guardrail 1 is connected to the bottle hanging mold mounting frame 5, and the bottle hanging mold mounting frame 5 is connected to the bottle hanging mold mounting plate 7 through the two bottle hanging support rods 6. The bottle hanging mold mounting plate 7 is connected to the upper end of the screw lifting hollow shaft 12.

[0029] Specifically, the screw mounting assembly has two fixed seats 8 and a rotating shaft 9. The rotating shaft 9 is rotatably connected between the two fixed seats 8. The conveying screw 2 is connected to the rotating shaft 9. One end of the rotating shaft 9 passes through the fixed seat 8 and is connected to a drive motor. The two fixed seats 8 are connected to the two ends of the fixed shaft 11, and the fixed shaft 11 is connected to the bottle hanging mold mounting plate 7.

[0030] Specifically, the bottle barrier installation assembly includes a mounting bracket 10, which is connected to two bottle hanging support rods 6 and the bottle barrier 3.

[0031] Specifically, after the medicine bottle 4 is capped, it is transferred from the capping station to the discharge channel through the cooperation of the discharge star wheel and the mesh belt. After entering the discharge channel, the medicine bottle is hung on the bottle hanging guard 1. At this time, the T-shaped slide 13 of the bottle hanging guard 1 locks the neck of the medicine bottle 4. The drive motor drives the rotating shaft 9 to rotate, and the rotating shaft 9 drives the conveying screw 2 to rotate. The medicine bottle 4 is located in the groove of the conveying screw 2. The rotation of the conveying screw 2 pushes the medicine bottle 4 to move and discharge. The bottle blocking guard 3 restricts the medicine bottle 4 to remain in the groove of the conveying screw 2 during the movement, until it is transferred to the discharge mesh belt or the next process to complete the discharge.

[0032] Specifically, the bottle hanging guardrail 1 has multiple ventilation slots 14 to reduce the impact on laminar airflow.

[0033] Specifically, the conveying screw 2 and the bottle-blocking guardrail 3 are aligned and placed opposite each other. The side of the bottle-blocking guardrail 3 and a single groove of the conveying screw 2 form a space the size of the diameter of the medicine bottle 4, so that the bottle can stand upright in the spiral groove.

[0034] Specifically, a bottle hanging guardrail 1 is provided above the conveying screw 2 and the bottle guardrail 3. The bottle hanging guardrail 1 is milled with a T-shaped groove 13. The T-shaped groove 13 is horizontal and its through direction is consistent with the feeding direction of the screw.

[0035] Specifically, after the medicine bottle 4 enters the spiral groove, the rotating conveyor screw 2 forces the medicine bottle 4 forward. Afterward, each bottle is individually separated by the grooves, preventing them from leaning against each other. By changing the pitch of the conveyor screw 2, the distance between adjacent bottles can be altered. Simultaneously with the medicine bottle 4 entering the spiral groove, the bottle neck enters the T-shaped groove 13 milled into the bottle hanging guard 1. The narrow opening of the T-shaped groove 13 holds the bottle neck in place, preventing it from falling.

[0036] like Figure 7 As shown, the force analysis of the medicine bottle 4 when driven in the spiral groove is illustrated. The contact points between the spiral groove and the medicine bottle 4 are points a and b. At point a, F1 is the squeezing force exerted by the conveying screw 2 on the forward movement of the medicine bottle 4; at point b, F2 is the supporting force exerted by the conveying screw 2 on the medicine bottle 4; F3 is the frictional force generated by the bottle guardrail 3 on the medicine bottle 4; and f is the frictional force exerted by the bottle hanging guardrail 1 on the neck of the bottle. mg is the overall weight of the bottle 4. Due to the spiral groove processing method, the bottle body is almost vertical when it contacts points a and b. With the intervention of the frictional force f, a state of zero net torque can be formed, ensuring that the bottle remains vertical and does not tilt forward during operation.

[0037] The screw conveying bottle neck clamping mechanism replaces the bottle bottom track with the bottle hanging guardrail 1, clamps the bottle neck of the medicine bottle on the bottle hanging guardrail, and conveys the medicine bottle to the discharge mesh belt through the conveying screw, so that the friction between the bottle bottom track and the bottom of the medicine bottle is avoided, and scratches on the bottle are avoided.

[0038] The above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that the technical solutions recorded in the foregoing embodiments can still be modified, or some or all of the technical features can be replaced equivalently; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
