Abstract

The invention relates to a vertical lifting and rolling trimming device used on an automatic machine for sanding discs, and relates to a device for trimming sand chips implanted in the sanding disc by means of vertical lifting and rolling. The object of the present invention is to provide a device capable of automatically trimming implanted sand pieces. The device has a simple structure, saves energy, and greatly improves production efficiency while effectively ensuring product quality. In order to achieve the above object, the technical solution adopted in the present invention is: a vertical lifting and rolling trimming device used on an automatic machine for sanding discs, comprising a lifting cylinder and a fixing device connected to the lower end of the lifting cylinder, and the fixing device is located at the bottom of the lifting cylinder. It can move up and down as a whole under the control, and there are rollers movably connected to the fixing device. When the roller moves down with the fixing device and presses on the product, driven by the product's own rotation, the roller can rotate by itself. The invention is applied to the shaping of the sand sheet of the sand plate.

Description

A Vertical Lifting and Rolling Trimming Device Used on the Automatic Machine of Sand Sheet Tray

technical field

The invention relates to a device for trimming sand sheets implanted in a sand sheet tray by means of vertical lifting and rolling.

technical background

In the production process of the sand disc, after the sand disc is implanted into the disc, the sand disc needs to be trimmed to ensure its position and angle. However, at present, the trimming of the sand disc is still done manually, and the product quality level is not good. Qi, and its work efficiency is extremely low, affecting the rapid operation of the entire production process.

Contents of the invention

The purpose of this invention is to provide a device that can automatically trim implanted sand pieces. The device has a simple structure, saves energy, and greatly improves production efficiency while effectively ensuring product quality.

In order to achieve the above object, the technical solution adopted in the present invention is: a vertical lifting and rolling trimming device used on the automatic machine of the sand sheet disc, comprising a lifting cylinder and a fixing device connected to the lower end of the lifting cylinder, and the fixing device is located at the bottom of the lifting cylinder. Under the control, it can move up and down as a whole. There are rollers movably connected to the fixing device. When the roller moves down with the fixing device and presses on the product, driven by the product's own rotation, the roller can rotate by itself.

The fixing device includes a pressure head installed at the lower end of the lifting cylinder for positioning the center of the product. The middle part of the pressure head is movably connected with a roller bracket, and the lower end of the side part of the roller bracket is provided with a roller rod. There are scroll wheels. the

It can be seen from the above-mentioned technical features of the present invention that its advantages are: in this device, the rollers and the rotary pressure head rise and fall at the same time, so that the product entering and exiting this station will not affect the existing arrangement of the small pieces on the product, ensuring that the product Quality; the roller is driven by the product to rotate, no power is needed, the structure is simple, and energy is saved; the roller bracket in this device is movably connected to the middle of the indenter and can rotate around the indenter, so that the roller can be placed in any position of 360 degrees , which is beneficial to choose the best position without touching the sand sheet at the high point. the

Description of drawings

The present invention will compare by accompanying drawing and illustrate in conjunction with the mode of example:

Detailed ways

The present invention will be further described below in conjunction with accompanying drawing by embodiment:

Preferred embodiment

As shown in Figure 1, in this device, the pressure head is installed on the piston rod at the lower end of the cylinder, and the roller bracket for fixing the roller rod is installed on the pressure head at the same time. The upper part can rotate freely and flexibly, so that the roller will rise and fall with the lifting of the pressure head. Its working process can be described as: when the cylinder moves downward to make the pressure head press down the product, the roller presses on the product at the same time, and the rotation of the product drives the roller to rotate passively, so that the sand pieces on the product are arranged regularly and neatly, thus completing the repair. piece of work. After the completion, the product stops rotating, the cylinder goes up, the pressure head and the roller leave the product, and the above actions are repeated after the next product arrives.

All features disclosed in this specification, except mutually exclusive features, can be combined in any way.

Any feature disclosed in this specification (including any appended claims, abstract and drawings), unless expressly stated otherwise, may be replaced by alternative features which are equivalent or serve a similar purpose. That is, unless expressly stated otherwise, each feature is one example only of a series of equivalent or similar features.
