Description

Technical Field

[0001] This utility model relates to the field of injection molding, and in particular to a welding device for a feeder filter structure. Background Technology

[0002] Injection molding machines use a material extractor to transfer molten material into the mold cavity for injection molding to obtain the product. To ensure product quality, a replaceable filter structure is inserted at the outlet of the material extractor. This filter structure consists of several layers of filter screens with different mesh sizes stacked sequentially. To maintain the integrity of the filter structure, currently, one corner of the overlapping filter screens is usually bent. However, in actual use, this filter structure can create gaps at the edge of the material extractor's outlet, causing defects in the quality of the injection molded product. In addition, when workers handle and overlap filter screens of different specifications, they can easily confuse the stacking order, resulting in poor filtration efficiency.

[0003] Therefore, designing a simple and efficient processing device for this filter structure while avoiding filtration defects is a problem that needs to be solved by those skilled in the art. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a welding device for the filter screen structure of a material feeder. This device has a simple structure, is easy to operate, and can efficiently produce qualified filter screen structures for material feeders.

[0005] The technical solution of this utility model is: a welding device for a filter screen structure of a material extractor, including a workbench, a spot welding machine, and a storage cabinet. The spot welding machine is located behind the workbench, and the projection of the positive conductive column of the spot welding machine is located on the table surface of the workbench and moves along the height direction. The position of the negative conductive column of the spot welding machine is fixed, and the top of the negative conductive column is flush with the table surface of the workbench. The storage cabinet is fixed at one corner of the table surface of the workbench, and multiple shelves are arranged at intervals along the height direction in the storage cabinet for placing filter screens of corresponding mesh sizes.

[0006] The workbench has a notch, through which the negative conductive post of the spot welding machine passes, corresponding to the positive conductive post of the spot welding machine.

[0007] Two wear-resistant blocks are fixedly installed on the surface of the workbench, located on the front and rear sides of the notch, respectively.

[0008] The wear-resistant blocks are all made of wood and are fixed to the workbench surface with screws.

[0009] The top and front of the storage cabinet are both open.

[0010] The frame of the workbench is constructed by welding stainless steel rectangular tubes, and the workbench surface is made of wood.

[0011] The above technical solution has the following beneficial effects: 1. The welding device for the filter screen structure of the material extraction machine includes a workbench, a spot welding machine, and a storage cabinet. The spot welding machine is located behind the workbench. The projection of the positive conductive column of the spot welding machine is located on the table surface of the workbench and moves along the height direction. The position of the negative conductive column of the spot welding machine is fixed, and the top of the negative conductive column is flush with the table surface of the workbench. That is, the welding parts of the spot welding machine correspond to the table surface position. The storage cabinet is fixed to one corner of the workbench. Multiple shelves are spaced along the height of the storage cabinet to hold filter screens of corresponding mesh sizes. The filter screens (different mesh sizes) required for the material extraction machine's filter structure are stacked on their respective shelves. When processing the filter structure, the screens are taken out sequentially and overlapped to obtain a filter structure blank. The blank is transferred along the workbench until one corner is below the positive conductive post of the spot welding machine. The positive conductive post of the spot welding machine is moved downwards, allowing conductivity between the filter screen and the negative conductive post, forming a weld point at that corner of the blank. Multiple filter screens are spot welded together to form a whole. Repeating this process at least two weld points at the edge of the blank allows for efficient processing of a filter structure that effectively meets the requirements of the material extraction machine.

[0012] 2. A notch is provided on the workbench surface. The negative conductive post of the spot welding machine passes through the notch and corresponds to the positive conductive post of the spot welding machine. Two wear-resistant blocks are fixedly installed on the workbench surface, located on the front and rear sides of the notch respectively. They form a circumferential shield for the negative conductive post of the spot welding machine, preventing interference between the filter screen blank and the negative conductive post of the spot welding machine during the transfer process, which would cause deformation of the filter screen edge and ensure the processing quality of the filter screen structure. The wear-resistant blocks also serve as consumable parts, reducing wear on the workbench surface.

[0013] 3. The top and front of the storage cabinet are open, making it convenient for staff to observe the amount of filter screens of each mesh size, and also convenient for staff to take out and store filter screens.

[0014] The following description, in conjunction with the accompanying drawings and specific embodiments, provides further details. Attached Figure Description

[0017] See Figure 1 and Figure 2This is a specific embodiment of a welding device for a material extraction machine filter screen structure. The welding device for the material extraction machine filter screen structure includes a workbench 1, a spot welding machine 2, and a storage cabinet 3. The spot welding machine is a conventional welding equipment available on the market. In this embodiment, the positive electrode conductive post of the spot welding machine is located above the negative electrode conductive post, and the positive electrode conductive post can move in the vertical direction while the position of the negative electrode conductive post is fixed. The frame of the workbench is constructed by welding stainless steel rectangular tubes, and the workbench surface is made of wood. The workbench is fixed to the top of the frame, thus forming the workbench. The spot welding machine 2 is located behind the workbench 1. The projection of the positive conductive post 21 of the spot welding machine 2 is located on the workbench surface and moves along the height direction. The position of the negative conductive post 22 of the spot welding machine is fixed, and the top of the negative conductive post 22 is flush with the workbench surface. In this embodiment, a notch 4 is provided on the workbench surface. The negative conductive post 22 of the spot welding machine passes through the notch 4 and corresponds to the positive conductive post 21 of the spot welding machine. Two wooden blocks are fixed on the workbench surface by screws as wear-resistant blocks 5, located in front of and behind the notch 4 respectively. Obviously, the top surface of the wear-resistant block is higher than the top of the negative conductive post. The storage cabinet 3 is fixed to the left corner of the workbench. Multiple shelves 31 are arranged at intervals along the height of the storage cabinet 3 to hold filter screens of corresponding mesh sizes. Specifically, the storage cabinet and shelves are made of wood, and the top and front of the storage cabinet 3 are open. The number of shelves is three, that is, there are a total of three layers of filter screens for preparing the filter screen structure of the feeder.

[0018] The working principle of this utility model is as follows: Taking the preparation of a square filter structure as an example... Workers take a metal filter screen (with different mesh counts) from the third, second, and first shelf in sequence and stack them on the workbench, aligning the four corners to obtain a filter screen structure blank. The filter screen structure blank is then transferred to the wear-resistant block, with one corner of the blank positioned between the positive and negative conductive posts. The positive conductive post of the spot welding machine is moved downward, and a spot weld is made at that corner of the blank, connecting the three filter screens into a whole. This process is repeated to create spot welds at other triangular points on the blank to obtain a qualified filter screen structure.
