Description

Technical Field

[0001] The utility model relates to the technical field of screen processing, in particular to a feeding device used for screen polishing. Background Art

[0002] Metal mesh is the collective name of metal and wire mesh. Wire mainly refers to wire made of metal or non-metal; mesh is made of wire and woven into meshes of different shapes, densities and specifications according to demand. Metal mesh is made of steel wire and copper wire. The wires are thick and thin, and the mesh holes are large and small. There are many types. It is customary to call the thick wire with large holes "net", the medium wire with medium holes "yarn", and the thin wire with small holes "cloth". After the wire mesh is welded and formed, it is usually polished and brightened before use because its welding points are black. When polishing the wire mesh, it is necessary to use manpower or equipment to load the wire mesh. By transporting the wire mesh to the designated position, it is convenient for the grabbing device to grab the wire mesh and send it to the polishing station for processing.

[0003] In the loading work of screen polishing, workers usually place the screen on the polishing equipment for polishing. The degree of automation is low and it is easy to cause scratches on the workers. The equipment used to complete the loading of the screen is usually difficult to meet the loading work of multiple screens of different sizes or styles at the same time, which makes its application scope narrow. Therefore, in view of the above problems, a loading equipment for screen polishing is proposed. Utility Model Content

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0032] The technical solutions in the embodiments of the present application are to solve the problems in the above-mentioned background technology, and the general idea is as follows:

[0033] As Figure 1As shown in the figure, a feeding device for screen polishing provided in this embodiment includes a substrate 1, on which a rotating table 2 is installed, and two screen placement plates 3, both of which are installed on the rotating table 2 and can switch their positions with each other following the rotation of the rotating table 2. There are two groups of positioning rods 4, which are respectively installed on the two screen placement plates 3, and a jacking rod 6, which is used to jack up the stacked screens. A lead screw drive mechanism 5 is used to drive the jacking rod 6 to move up and down. Through the above structural form, the two screen placement plates 3 arranged on the rotating table 2 can cooperate with the positioning rods 4 to stack the screens of different sizes or styles neatly together. In the way that the lead screw drive mechanism 5 drives the jacking rod 6 to move upward, the stacked screens are jacked up to a specified height, which is convenient for the grasping device to grasp and convey at a fixed point. It has a high level of automation. And when it is necessary to change the size or form of the screen for polishing, the feeding object can be switched by rotating the rotating table 2, so that the jacking rod 6 can jack up the screens of different sizes or forms, making the feeding more flexible.

[0034] Specifically, there are four positioning rods 4 arranged on one of the screen placement plates 3 in a circumferential array, and six positioning rods 4 arranged on the other screen placement plate 3 symmetrically. Through the above structural form, the positioning rods 4 with different arrangement forms can be used to achieve the positioning and stacking effect of screens of different sizes or forms, so that the screens can be stacked neatly together. And when the jacking rod 6 jacks it up, it will also move upward along the positioning rods 4 and keep neat under the restraint of the positioning rods 4.

[0035] As Figure 3 shown in the figure, the lead screw drive mechanism 5 includes a mounting base 51, on which a slide table 52 is slidably arranged. At the same time, a driving motor 53 with an output shaft fixedly connected to a transmission lead screw 54 is installed at the top of the mounting base 51, and the transmission lead screw 54 is threadedly connected to the slide table 52. Through the above structural form, the driving motor 53 can drive the transmission lead screw 54 to rotate, so as to drive the slide table 52 threadedly connected to it to drive the jacking rod 6 to move up and down.

[0036] In addition, the bottom end of the jacking rod 6 is threadedly connected to the slide table 52, and a support plate 61 is installed at its top end. Through the above structural form, it is convenient for disassembling and repairing the jacking rod 6. At the same time, the support plate 61 can increase the contact area between the top end of the jacking rod 6 and the screen, avoiding the screen being deformed under pressure due to too small contact area and affecting normal use.

[0037] As Figure 2As shown in the figure, a jacking groove 31 is centrally formed on the wire mesh placement plate 3, and the cross-sectional dimension of the jacking groove 31 is the same as that of the support plate 61. With the above structural form, the support plate 61 can pass through the provided jacking groove 31 to jack up the stacked wire meshes. At the same time, the jacking groove 31 with such a dimension is the form of the smallest opening, which can have the largest contact area with the wire mesh, thus effectively supporting the wire mesh and avoiding deformation due to insufficient support of the wire mesh caused by an overly large notch.

[0038] As Figure 4 shown in the figure, the rotating table 2 includes a rotating shaft seat 22 installed on the base plate 1. A table plate 21 is installed on the rotating shaft seat 22. At the same time, an installation frame 23 is fixedly arranged on the lower end surface of the base plate 1, and a 180-degree rotating cylinder 24 is arranged in the installation frame 23. With the above structural form, the table plate 21 has a structural basis for free rotation, and at the same time, the 180-degree rotating cylinder 24 provides a necessary power basis for the rotation of the table plate 21.

[0039] Among them, the rotating shaft seat 22 is composed of a cylindrical outer shell and a rotating shaft rotatably arranged in the cylinder through a bearing. The top end of the rotating shaft is fixedly connected to the table plate 21, and the bottom end of the rotating shaft is in transmission connection with the output shaft of the 180-degree rotating cylinder 24 through a transmission gear set 25. With the above structural form, the 180-degree rotating cylinder 24 can drive the rotating shaft to reciprocally rotate by 180 degrees, so that the table plate 21 can reciprocally rotate by 180 degrees, and then rotate different wire mesh placement plates 3 above the jacking rod 6 to realize the switching work of wire meshes of different sizes or forms.

[0040] As Figure 2 shown in the figure, two symmetrically arranged passing grooves 201 are formed on the table plate 21. At the same time, a number of connecting screws 202 for fixedly installing the wire mesh placement plate 3 are fixedly arranged on the table plate 21. With the above structural form, the passing grooves 201 provide a necessary structural basis for the passing of the support plate 61, while the connecting screws 202 provide a necessary structural basis for the fixed installation of the wire mesh placement plate 3.

[0041] As Figure 2 shown in the figure, a rod distance adjustment groove 32 is formed on the wire mesh placement plate 3. The bottom of the positioning rod 4 is slidably arranged in the rod distance adjustment groove 32, and a fastening nut is threadedly connected to the bottom end of the positioning rod 4. With the above structural form, the positioning rods 4 can adjust the distance between each other by sliding in the rod distance adjustment groove 32 to adapt to the placement of wire meshes of different sizes. After the distance adjustment is completed, the position of the positioning rod 4 can be fixed with the fastening nut.

[0042] The usage principle and usage process of the present utility model:

[0043] The two wire mesh placement plates 3 arranged on the rotating table 2 can cooperate with the positioning rods 4 to neatly stack wire meshes of different sizes or styles together to achieve the function of storage. When feeding is required, the driving motor 53 drives the transmission lead screw 54 to rotate, and the sliding table 52 threadedly connected thereto drives the lifting rod 6 to move up and down, lifting the stacked wire meshes to a specified height, facilitating the fixed-point grasping and conveying by the grasping device, with a high level of automation. Among them, a support plate 61 is installed at the top of the lifting rod 6, and the support plate 61 can increase the contact area between the top of the lifting rod 6 and the wire mesh, avoiding deformation of the wire mesh under pressure due to too small contact area and affecting normal use.

[0044] When it is necessary to change the size or form of the wire mesh to be polished, the 180-degree rotating cylinder 24 can be used to drive the rotating shaft to reciprocate by 180 degrees, so that the table plate 21 can reciprocate by 180 degrees, and then different wire mesh placement plates 3 can be rotated above the lifting rod 6, enabling the lifting rod 6 to lift wire meshes of different sizes or forms, making the feeding more flexible.

[0045] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
