Automatic backing plate for workbench of film covering machine

Abstract

The invention discloses an automatic backing plate for the workbench of a film covering machine, and relates to the field of woodworking machines. The automatic backing plate comprises a backing plate block (1), a locking rod (2), a support (4) and an ejector rod (6). The backing plate block (1) is of a hollow structure and comprises two split parts, namely, an upper part (11) and a lower part (12). A spring (3) is sleeved on the locking rod (2) which passes through the hollow part of the backing plate block (1) and is capable of moving. Steel balls (5) are arranged below the locking rod (2). The backing plate block (1) is connected with the ejector rod (6). The support (4) is sleeved out of the backing plate block (1) and the ejector rod (6). The automatic backing plate provided in the invention has a simple construction and totally employs a mechanical structure, which enables low cost; the plate can be mounted on different film covering machine workbenches and produces a same film covering effect as an imported microcomputer-controlled automatic backing plate does, thereby reducing production cost for an enterprise and enabling the enterprise to use the saved capital for expanded production so as to accelerate the development of the enterprise.

Description

technical field [0001] The invention relates to the field of woodworking machinery, in particular to an automatic backing plate for a laminating machine workbench. Background technique [0002] At present, the automatic backing plate of the workbench of the domestic laminating machine mainly adopts the automatic backing system controlled by the imported microcomputer. The bottom of the backing plate is equipped with an electromagnetically controlled integrated circuit. The operation must first go through a scan, and the integrated circuit at the bottom of the backing plate where the workpiece is placed receives When the signal rises automatically, it is a certain distance above the workbench, and then the laminating process is carried out. The entire operation process is automatically controlled, and it is precisely because of the use of integrated circuits and microcomputer control that the cost is high. The cost of each machine using this microcomputer-controlled backing s...

Problems solved by technology

The entire operation process is automatically controlled, and it is precisely because of the use of integrated circuits and microcomputer control that the cost is high. The cost of each machine using this microcomputer-controlled backing system is about one million yuan, and many companies are not capable of introducing such a system. High-cost equipment has brought obstacles to the development of enterprises
