Description

Technical Field

[0001] The utility model discloses a downward pressing limit mechanism, belongs to the technical field of wine cap production equipment, and specifically relates to an automatic downward pressing limit mechanism based on gravity. Background Art

[0002] The production process of plastic bottle caps includes raw material processing, melt extrusion, mold forming and quality inspection.

[0003] Raw material processing: After processing the plastic raw materials, granular materials that meet production requirements are obtained, which generally includes loose material washing, material separation, granulation, etc.

[0004] Melt extrusion: The pre-processed pellets are placed in the extruder for melting, and the molten plastic is extruded into shape by pressure.

[0005] Moulding: The extruded plastic is molded through a mould to form the desired bottle cap shape. The molding methods include pressure molding, injection molding, etc.

[0006] Quality inspection: The formed bottle caps are inspected for appearance, size, tensile strength and other quality inspection indicators to ensure that the product quality meets the requirements.

[0007] In the above steps, the bottle caps need to be circulated, and usually the bottle caps are transferred by the circulating sampling clamps. However, the clamping jaws in the prior art automatically fix the two sides of the bottle caps when clamping the bottle caps, and cannot fix the top. At the same time, there are many mechanisms that use cylinders to press down, but this structure is complicated and sometimes the bottle caps will be pushed out. Utility Model Content

[0026] An automatic downward pressure limiting mechanism based on gravity, comprising: a downward pressure frame 1, a downward pressure rod 2, a first sliding sleeve 3, a second sliding sleeve 4, a spring 5 and a pressure seat 6;

[0027] One end of the lower pressure rod 2 is fixedly installed on the bottom of the lower pressure frame 1, and the first sliding sleeve 3 and the second sliding sleeve 4 are sequentially sleeved on the lower pressure rod 2 and are slidably connected; the pressure seat 6 is fixedly installed on the other end of the lower pressure rod 2, and the spring 5 is sleeved on the other end of the lower pressure rod 2.

[0028] In one embodiment, Figures 1 to 4 As shown, the lower pressing frame 1 is square-shaped, and the lower pressing rod 2, the first sliding sleeve 3, the second sliding sleeve 4, the spring 5 and the pressing seat 6 are provided in four groups, each group being installed at the turning foot of the lower pressing frame 1.

[0029] In one embodiment, Figures 1 to 4As shown, the automatic downward-pressing limiting mechanism is installed on a support plate 7 , a driving assembly 8 is provided on the support plate 7 , a clamping jaw assembly 9 is provided at the bottom, and the driving assembly 8 is connected to the clamping jaw assembly 9 .

[0030] In one embodiment, Figures 1 to 4 As shown, the driving assembly 8 includes: a cylinder 10, which is fixedly mounted on the support plate 7 and the bottom of which is connected to the clamping assembly 9; a third sliding sleeve 11, which is fixedly mounted on the support plate 7; and a sliding rod 12, one end of which is sleeved in the third sliding sleeve 11 and passes through the support plate to be connected to the clamping assembly 9.

[0031] In one embodiment, Figures 1 to 4 As shown, the third sliding sleeve 11 and the sliding rod 12 are provided in four groups;

[0032] A right cross frame 13 is provided between the two slide bars 12 , and an elastic buffer block 14 is provided on the cross frame 13 .

[0033] In one embodiment, Figures 1 to 4 As shown, the first sliding sleeve 3 is fixedly mounted on the support, and the second sliding sleeve 4 is fixedly mounted on the clamping jaw assembly 9 .

[0034] Working principle: When the utility model works, it is divided into the following processes:

[0035] When there is no work, the pressing rod 2 in the automatic pressing limit mechanism drives the pressing seat 6 to the bottom;

[0036] When working, first the driving assembly 8 uses the cylinder 10 to drive the clamping jaw assembly 9 to move downward, so that the slide rod 12 moves in the third slide sleeve 11. When it moves to the specified position, the clamping jaw assembly 9 works to clamp the bottle cap, thereby using the cylinder 10 for return. As the cylinder 10 moves upward, the bottle cap on the clamping jaw assembly 9 is driven to contact the pressure seat 6 in the automatic downward pressure limiting mechanism, thereby driving the downward pressure rod 2 to move upward with the upward thrust, thereby realizing the top limit of the bottle cap. When the clamping jaw assembly 9 puts down the bottle cap, the downward pressure rod 2 has no thrust at this time, and uses the inertia of gravity to move downward.

[0037] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
