Auxiliary device for processing hollow welded mesh by mesh welding machine

Abstract

The present invention discloses an auxiliary device for processing hollow welding mesh by a welding mesh machine, which comprises a lifting device, a slide, a moving plate, a positioning plate and a push plate. Two lifting devices are installed at both ends of the feeding frame and support the slide, so that the slide can move up and down; the positioning plate is connected to the moving plate and placed on the upper part of the slide, so that the moving plate can move horizontally on the slide; the push plate is installed on the moving plate, and the pull rope is fixed to the push plate. The push plate can move forward and backward on the moving plate by the traction of the pull rope. When working, the short warp is placed in the groove on the moving plate, and the moving plate is pushed by the push rod to align the short warp with the threading hole. At this time, the pull rope can be pulled to drive the push plate to move forward and push the short warp into place, thereby completing the warp threading work. The device can enable the operator to avoid the operation of climbing up the frame to insert the short warp for each piece of mesh produced, thereby reducing labor intensity and improving production efficiency.

Description

Technical Field

[0001] The invention belongs to the field of steel bar welded mesh processing equipment, and in particular relates to an auxiliary device in the processing of steel bar welded mesh equipment. Background Art

[0002] Steel welded mesh is mainly used in reinforced concrete structures. However, during the paving process, bosses and caissons are often encountered, especially in the prefabricated residential concrete panels, such as doors and windows, which form hollows in the middle of the welded mesh, forming a hollow welded mesh. At present, the most efficient way to form a hollow welded mesh is to use a dedicated hollow welded mesh forming equipment for direct production. Due to the high production efficiency of continuous operation, the purchase cost of special equipment is high. If the market capacity of this type of mesh is not large, the manufacturing cost will be too high. There are also conventional mesh machines to produce a whole welded mesh, which is manually cut after completion, but the cut materials cannot be used and are only treated as waste, resulting in a large amount of waste. Not only is the economy poor, but the production efficiency is low. Previously, a method for producing hollow welded mesh on conventional welded mesh processing equipment was invented. Adjustments were made in the production process, changing the warp threading once to multiple distributed threading, and the weft thread cutting and reuse reduced the production cost while meeting the production requirements. However, the threading methods of the warp and weft in this method are all manual distribution threading. Due to the structural limitations of the mesh machine, workers have to climb onto the equipment body to operate the threading of some warps, which is not only labor-intensive and inefficient, but also has safety hazards. Summary of the invention

[0003] The present invention provides an auxiliary device for threading the warp when conventional welding mesh processing equipment produces hollow welding mesh, so as to solve the inconvenience caused by workers climbing up the equipment to operate, and at the same time, improve the corresponding production efficiency.

[0004] When using conventional mesh welding equipment to process the mesh, firstly, the short warp is manually inserted into the threading hole, and then the warp feeding mechanism feeds the standard warp into the threading hole, and the mesh welding machine starts working. After the first hole is processed, the feeding mechanism feeds the long warp into the threading hole and starts welding until the second hole is processed. Then, the second batch of short warp is manually inserted into the threading hole until the whole mesh is welded. Since the short warp needs to be manually inserted into the threading hole, it is inconvenient and inefficient.

[0005] The auxiliary device for processing hollow welding mesh by welding mesh machine of the present invention adopts the auxiliary device which can be completed beside the machine without climbing up the frame. It comprises a lifting device, a slide, a moving plate, a positioning block and a push plate. Two lifting devices are installed at both ends of the feeding frame and support the slide, so that the slide can move up and down. The lifting device adopts a cylinder; the positioning block connects the moving plate and is placed on the upper part of the slide, so that the moving plate can move horizontally on the slide; the push plate is installed on the upper part of the moving plate and can move forward and backward on the upper part of the moving plate. The upper part of the moving plate is provided with a groove according to the relative position of the short warp, and the lower part of the push plate is inserted into the guide groove opened on the moving plate, so that the push plate does not deflect when moving. The lower part of the push plate has a hole, and the pull rope passes through the hole and is fixed by a fixing bolt. The push plate can move forward and backward on the moving plate by the traction of the pull rope. In order to reduce the running resistance, guide pulleys are installed at the front and rear of the moving plate, and a push rod is also installed on the moving plate. The operator moves the moving plate on the slide through the push rod.

[0006] When the auxiliary device of the hollow welding mesh is in use, the operator is located on one side of the feeding frame and puts the short warp into the groove on the moving plate. At this time, the push plate is at the rear of the moving plate. The moving plate is pushed to the corresponding position on the slide by the push rod, so that the short warp is aligned with the threading hole. The pull rope at the front end of the moving plate is pulled to drive the push plate forward and push the short warp into place, thereby completing the warp threading work. Subsequently, the push rod is pulled to return the moving plate to its original position. At this time, the slide can be raised by the lifting device to avoid interference between the feeding mechanism and the slide when sending the long warp into the threading hole. In the next step, the operator pulls the pull rope at the rear end of the moving plate to drive the push plate to move backward and into place, and then puts the short warp into the moving plate. The same principle is repeated to pass the second short warp.

[0007] By using the hollow mesh welding auxiliary device, operators avoid having to climb up the frame to insert the short warp threads for each mesh produced, thereby reducing labor intensity and improving production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
