Description

A new type of demoulding device for the box forming machine of heaven and earth cover

technical field

The utility model relates to the technical field of carton forming machinery, in particular to a new demoulding device for a heaven and earth cover carton forming machine.

Background technique

Tiandi cover carton is a common packaging box style, which is mostly used in gift boxes, shoe boxes, and mobile phone packaging boxes, including the lower cover used to hold the product, and the upper cover directly on the lower cover. The general upper cover can be covered part of the lower cover, or the upper cover completely covers the lower cover.

At present, the industry adopts automatic carton forming machines. The working table is equipped with a box mold device, an upper hemming device, a lower hemming device and a demoulding device, and the carton blank is sent to the working table from top to bottom through the clamping device. , and then through the upper hemming device and the lower hemming device in turn to cover the outer skin on the front and rear sides and the left and right sides of the carton embryo body, and finally the carton is ejected from the mold by the demoulding device. In the existing carton forming machine, the demoulding device is provided with a demoulding cylinder under the workbench, and the demoulding cylinder pushes the bottom mold fixing plate upwards, thereby utilizing the bottom mold fixing plate to push the carton up for demoulding.

However, there must be offset vibrations in the up and down strokes of the demoulding cylinder, so the direction of the bottom mold fixing plate is easy to get out of control, which may cause deformation of the carton to be demoulded, or damage the carton.

Utility model content

In order to make up for the shortcomings of the above-mentioned prior art, the utility model provides a new type of demoulding device for the box forming machine of the world cover, which effectively reduces the vibration generated during the up and down strokes of the demoulding cylinder and makes the demoulding process more stable .

In order to achieve the above object, the utility model adopts the following technical solutions.

A new demoulding device for a heaven and earth cover carton forming machine, comprising a workbench and a demoulding device arranged at the lower part of the workbench, the demoulding device comprising:

a knockout cylinder having a cylinder housing and a piston rod protruding from the bottom of the cylinder housing;

The bottom mold fixing plate is arranged on the upper end of the cylinder shell;

The buffer fixing plate is arranged at the lower end of the cylinder shell, and a linear bearing is respectively arranged on the front and rear sides;

The three-axis fixed plate is arranged at the bottom end of the piston rod;

Cylinder guide rods, including two vertical ones, one end of which is connected to the workbench, and the other end passes through the linear bearing downwards to connect with the three-axis fixed plate;

The demoulding fixing rods include two vertical ones arranged on the left and right sides of the buffer fixing plate, one end of which is connected to the workbench, and the other end is connected to the three-axis fixing plate.

Compared with the prior art, the utility model has the beneficial effects of:

By buffering the cylinder guide rods on the front and rear sides of the fixing plate and the demoulding fixing rods on the left and right sides of the three-axis fixing plate, the demoulding cylinder realizes the ideal limit in the up and down strokes, whether it is lateral offset or longitudinal offset, effectively The vibration generated during the up and down process of the demoulding cylinder is greatly reduced, so that the demoulding process is more stable, the probability of deformation or damage of the carton after demoulding is lower, and the yield rate is improved.

The utility model will be further described below in conjunction with the accompanying drawings and specific embodiments of the description.

Detailed ways

As shown in Figures 1 and 2, a new type of demoulding device for a heaven and earth cover carton forming machine includes a workbench 1 and a demoulding device 2 located at the bottom of the workbench 1, and the demoulding device 2 includes:

The demoulding cylinder 3 has a cylinder shell 31 and a piston rod 32 stretched out from the bottom of the cylinder shell 31;

Bottom mold fixing plate 4 is located on the upper end of the cylinder shell 31;

The buffer fixing plate 5 is arranged at the lower end of the cylinder shell 31, and a linear bearing 51 is arranged on the front and rear sides respectively;

The three-axis fixed plate 6 is located at the bottom end of the piston rod 32;

The cylinder guide rod 7 includes two vertically arranged ones, one end of which is connected to the workbench 1, and the other end passes through the linear bearing 51 and is connected with the three-axis fixed plate 6 downward;

The demoulding fixed rod 8 includes two vertically arranged ones, which are arranged on the left and right sides of the buffer fixed plate 5, one end of which is connected with the workbench 1, and the other end is connected with the three-axis fixed plate 6.

A new demoulding device of a heaven and earth cover carton forming machine in the above technical solution, its working principle is as follows:

The cylinder guide rod 7 cooperates with the linear bearing 51 to realize the limitation of the front and rear longitudinal orientation during the up and down stroke of the demoulding cylinder 3; while the demoulding fixing rod 8 cooperates with the cylinder guide rod 7 through the three-axis fixing plate In the up and down strokes of the cylinder 3, the positioning of the left and right lateral orientations is realized. Therefore, during the up and down strokes of the demoulding cylinder, both the lateral offset and the longitudinal offset have achieved an ideal limit, which effectively reduces the vibration generated during the up and down process of the demoulding cylinder, thereby making the demoulding process more stable and paper-free. The probability of deformation or damage after the box is demoulded is lower, which improves the yield rate.

As an improvement of the above technical solution, the two cylinder guide rods 7 are symmetrically arranged around the center axis of the demoulding cylinder 3 . The symmetrically arranged cylinder guide rods 7 make the position-limiting effect of the front and rear longitudinal orientations more stable during the up and down strokes of the demoulding cylinder 3 .

As an improvement of the above technical solution, the two demoulding fixing rods 8 are symmetrically arranged around the central axis of the demoulding cylinder 3 . The symmetrically arranged demoulding fixing rods 8 make the limiting effect of the left and right lateral directions more stable in the up and down strokes of the demoulding cylinder 3 .

For those skilled in the art, various other corresponding changes and deformations can be obtained according to the structures and principles disclosed in the present utility model, and all these changes and deformations belong to the protection category of the present utility model.
