Technical Field

[0001] The utility model belongs to the technical field of product opening precision correction equipment, in particular to a product opening precision self-correction structure. Background Art

[0002] "Product opening accuracy" generally refers to the manufacturing precision of a product's opening, and is particularly important when it comes to packaging or containers. This involves aspects such as the product's opening size, shape, and edge smoothness. Product opening accuracy is crucial for ensuring product functionality, user experience, and packaging sealability. To ensure consistent opening accuracy after production, opening accuracy correction equipment is typically used to adjust the product's opening.

[0003] The opening precision correction device in the prior art has a precision adjustment mechanism of a horizontal structure. Since the opening of each product will have slight differences, if a horizontal structure adjustment mechanism is used, the position of the adjustment mechanism needs to be adjusted frequently, and the opening precision correction efficiency is low. In order to solve the above problem, a product opening precision self-correction structure is proposed. Utility Model Content

[0009] Through the above technical solution, the installation position of the limit block is changed, thereby changing the depth of the equipment entering the product opening during the repair process.

[0010] In a preferred embodiment, the upper opening precision control block and the lower opening precision control block located on the left sides of the upper fixing plate and the lower fixing plate are both inclined structures.

[0011] Through the above technical solution, for products with different opening degrees, the precision control blocks with inclined structures can make the equipment flexible, without the need to frequently change the distance between the precision control blocks, thereby improving the correction efficiency.

[0017] In a preferred embodiment, a connecting rod is fixedly mounted on one side of the movable plate by means of bolts, a transmission rod is hingedly connected to one side of the connecting rod, and a handle is hingedly connected to one side of the transmission rod.

[0018] Through the above technical solution, the device is manually reset by pulling the handle to drive the movable plate to move along the slide rail.

[0019] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are as follows: the present invention proposes a product opening precision self-correcting structure.

[0020] When adjusting the opening accuracy of the product, the adjustment bolt is rotated and the spacing between the upper fixed plate and the lower fixed plate is changed through the adjustment bolt, so that the height between the upper opening accuracy control block and the lower opening accuracy control block is adjusted to the required position.

For products with different opening degrees, the accuracy control block with a slope structure can make the equipment flexible, and there is no need to frequently change the distance between the accuracy control blocks, thereby improving the correction efficiency.
