Description

Technical Field

[0001] The utility model relates to the field of bottle preform conveying equipment, in particular to a bottle preform jamming prevention structure of a bottle preform conveying device. Background Art

[0002] A preform conveying device is a mechanical device specifically used to transport preforms from one location to another via guide rails, using protrusions or grooves on a star wheel to contact the bottom or side of the preform. However, this method of moving the preform by only contacting one side of the preform causes the preform to be biased to one side due to centrifugal force at a bend in the guide rail, causing excessive pressure on the contact point between the star wheel and the preform, while other parts are suspended or unstable. The uneven force makes it easy for the preform to get stuck.

[0003] For example, the utility model patent (application number: 201220715846.X) discloses a "preform conveying device." Its specification discloses: "This preform conveying device comprises a base, a turntable mounted on the base and rotatable by an external force, and a guide rail located around the turntable's circumference. Several retaining slots are provided along the turntable's circumference. The guide rails are characterized by inner and outer rails, forming a preform conveying track between the inner and outer rails. The ends of the guide rails form a preform inlet and outlet, respectively. The retaining slots of the turntable are located within the preform conveying track." This utility model has the advantages of a simple structure, stable transmission, and a reduced size for preform production equipment. The aforementioned patent serves to address the shortcomings of the prior art.

[0004] Therefore, we have made improvements to this problem and proposed an anti-stuck preform structure for the preform conveying device. Summary of the Invention

[0032] Further, such as Figure 2 and Figure 3 As shown, the guide assembly 2 includes a first guide plate 201 located on one side above the mounting base 1. The first guide plate 201 and the second guide plate 202 are arc-shaped. The first guide plate 201 and the second guide plate 202 serve as guide rails in the conveying device, and the arc serves as the turning point of the guide rails. A second guide plate 202 is provided on one side of the first guide plate 201. The protruding edge above the preform is used between the first guide plate 201 and the second guide plate 202 to lift the preform onto the first guide plate 201 and the second guide plate 202, so that the bottle body is located between the first guide plate 201 and the second guide plate 202.

[0033] Further, such as Figure 2 and Figure 3 As shown, the blocking assembly 3 includes a No. 1 blocking plate 301 located above the No. 1 guide plate 201, and a No. 2 blocking plate 302 is provided above the No. 2 guide plate 202. The No. 1 blocking plate 301 and the No. 2 blocking plate 302 are used to cooperate with the contact member to prevent the bottle blank from warping.

The motor 501 is used to drive the rotating member to rotate through the transmission rod 502, and the output end of the motor 501 is fixed with a transmission rod 502.

[0035] Further, such as Figure 1 and Figure 4As shown, the rotating member includes a rotating disk 601 fixed to the top of the transmission rod 502. The rotating disk 601 is used to drive the bottle body to slide on the guide assembly 2 through the contact member. The contact member contacts the top of the bottle body and drives it to rotate. The top of the bottle body is pressed and driven to move, which can effectively prevent the bottle body from tilting and getting stuck, and at the same time make the force point more stable.

[0036] Further, such as Figure 4 As shown, the contact member includes a contact ring 602 fixed to the bottom end of the rotating disk 601. The contact ring 602 contacts the top of the preform. When the rotating disk 601 rotates, the preform moves. At the same time, when the preform tilts, it will be blocked by the contact ring 602, thereby preventing it from tilting or tilting. One side of the contact ring 602 is located between the first blocking plate 301 and the second blocking plate 302. The first blocking plate 301 and the second blocking plate 302 further assist the preform in sliding as an additional safety measure. At the same time, the contact ring 602 will not be easily misaligned when sliding between the first blocking plate 301 and the second blocking plate 302, making its rotation more stable.

[0039] Further, such as Figure 1 and Figure 5 As shown, the top of the mounting base 1 is located above the outer side of the motor 501 and is provided with a slip ring 702. The slip ring 702 is located on the side of the No. 1 guide plate 201 close to the motor 501. A plurality of support plates 701 are fixed to the bottom end of the slip ring 702. The bottom end of the support plate 701 is fixedly connected to the mounting base 1. The slip ring 702 is slidably connected to the rotating disk 601 located at the top, so that the rotating disk 601 rotates more stably through the sliding connection and support with the slip ring 702.

[0040] Example 3

The original contact between the contact ring 602 and the bottle preform is changed to contact with the bottle preform through the anti-skid pad 603. The anti-skid pad 603 is specifically a rubber pad, which can play an anti-skid role and is more gentle when in contact with the bottle preform, thereby better driving the movement and preventing slipping.

[0042] The use process of the anti-preform jamming structure of the preform conveying device provided by the utility model is as follows:

[0043] When it is necessary to move the preform located between the first guide plate 201 and the second guide plate 202, the motor 501 is started to rotate the rotating disk 601 via the transmission rod 502. The rotating disk 601 contacts the preform via the anti-skid pad 603 below the contact ring 602, thereby causing the preform to move accordingly. The anti-skid pad 603 contacts the top of the preform to prevent the preform from tilting or tilting.
