Description

Technical Field

[0001] The utility model relates to the technical field of glass bottle manufacturing equipment, and more specifically to the technical field of a primary blank mold for Xiao Lang Jiu Background Art

[0002] During the production process of glass bottles, when the primary mold contacts the plug, insufficient shaping of the glass bottle may lead to various shaping quality problems. These problems may affect the appearance, structural integrity, function, and ultimate use of the glass bottle. A seam line will form at the bottom of the produced glass bottle. If such a seam line is too thick, it will result in defective glass bottles.

[0003] The seam line between the primary mold and the plug is commonly known as the plug line. The following are some shaping quality problems that may be affected by the plug line:

[0004] 1. The plug line is too thick: If the plug line at the bottom of the bottle is too thick, it will cut the hand and affect the use by customers.

[0005] 2. The plug line is skewed: If the plug line is not aligned with the center of the bottom of the forming mold, it will cause the anti-slip teeth at the bottom not to appear;

[0006] 3. The anti-slip teeth do not appear: The non-appearance of the anti-slip teeth at the bottom causes the bottle body to tilt;

[0007] 4. The production efficiency is reduced: Excessive production defects affect the production efficiency;

[0008] Therefore, the gap size at the joint between the primary mold and the plug is directly related to the thickness of the plug line and also affects problems such as the non-appearance of the anti-slip teeth at the bottom. After eliminating the plug line, the unqualified problems such as cracking, brightening, and roughness caused by the plug line can be solved; How to change the contact point between the plug and the primary mold to eliminate the plug line is the direction of effort for those skilled in the art.

[0054] Embodiment 5

[0055] This embodiment discloses a production process for the preliminary blank of Xiaolang liquor, which is specifically as follows:

[0056] (a), Blanking: In addition to strictly controlling the material temperature, material weight, and material type, attention should be paid to adjusting the scissors of the feeder so that after the material drop is cut off, it falls vertically;

[0057] (b), Feeding: Carefully adjust the straight material chute and the turning chute so that the material drops can quickly and smoothly pass through the receiving chute, the straight material chute and the turning chute, and accurately fall into the center of the blank mold without contacting the funnel. The material should be more than 20 mm above the bottom of the straight material chute, so that the material falls with as little contact with the straight material chute as possible and stably;

[0058] (c), Puffing: After the material drop falls into the blank mold, puffing should be carried out as soon as possible. The puffing time should be as short as possible, and the puffing pressure should be appropriate. The puffing time for long-neck bottles can be slightly longer;

[0059] (d), Reverse blowing: As soon as the puffing ends, the core should quickly descend to reheat the bottle mouth. The start time of reverse blowing should be appropriate, and the pressure should be suitable for different products. The pressure for products with less material should be smaller, and vice versa;

[0060] Note: The air flow of reverse blowing is sent through the core, and the core is cooled during the reverse blowing process. If the core still cannot be cooled by reverse blowing, reverse blowing can be carried out again after the mouth mold is flipped to further cool the core, but the air must be cut off before feeding;

[0061] (e), Flipping and exchanging: When the blank mold is opened, the mouth clamp drives the blank bottle to flip to the forming mold. The flipping speed and smoothness have a significant impact on the quality of the product and should be carefully adjusted to meet the requirements of the blank bottle;

[0062] (f), Positive blowing: After the forming mold is closed, the blowing head drops to carry out positive blowing. The pressure of positive blowing is related to the weight and shape of the bottle. The blowing pressure for larger products should be smaller;

[0063] (g), Cooling and blowing the bottle: The turntable rotates to the cooling and blowing position for cooling;

[0064] (h), Clamping out: After the forming mold is opened, the bottle clamping mechanism clamps and moves above the stop plate. The bottle is suspended in the bottle clamp and blown with cooling air above the stop plate for a period of time to initially cool the bottle, and then placed on the stop plate. This blowing time is very important for keeping the product unchanged in shape.

[0065] (i), Secondary expansion and contraction of bottle clamping: The bottle is placed by the secondary expansion and contraction of bottle clamping, and then sent to the bottle conveyor belt. By adjusting the bottle placing time, the residence time of the bottle on the stop plate can be controlled.

[0066] (j), Cooling air for the blank mold and the forming mold: At the beginning of production, air supply can be not provided first. Until the mold is hot enough to be about to stick to the material, air supply is started to cool the mold. Generally, it is more beneficial to use a hotter mold for bottle and jar production. Therefore, as long as the demolding is smooth, the cooling air can be minimized.
