Description

Technical Field

[0001] The utility model belongs to the technical field of nailing machines, and in particular relates to a nailing machine with stable wire feeding. Background Art

[0002] In woodworking, decoration, leather and other operations, nails are often needed to join objects. In order to improve the working efficiency and nailing effect, the industry has developed a nailing machine that can continuously nail. It mainly forms a nail groove group for accommodating nails and automatically feeding at the bottom of the casing, and a nailing plate is provided on the front edge of the casing that can be strongly fired downward by the action of an elastic member. When the nailing plate is selectively lifted up by the pressure handle, the nails in the nail groove group below will enter the firing position of the nailing plate one by one. Therefore, when the nailing plate is released by the pressure handle and fired downward, the nails located below can be strongly knocked out, allowing the nails to be nailed into the workpiece.

[0003] Reference authorization announcement number: CN111873095B Chinese authorized patent: A cylinder type nailing machine. This patent adopts the structure of inner and outer cylinders. The ring piston cylinder in the outer cylinder body drives the cutting and forming slider to cut and form. After the control valve is opened, the gas is instantly introduced into the inner cylinder, pushing the nailing rod in the inner cylinder to complete the nailing. The instantaneous impact force of nailing is large. For soft sponge cushions, nailing can be completed without flattening the sponge. It also has the advantage of compact structure.

[0004] The above patented machine head uses a cylinder-type wire clamping and wire feeding, which is unstable. The original machine head has instability in wire clamping force and wire feeding speed due to inconsistency in the wire feeding rod and difficulty in controlling the air pressure. There are problems such as the flat wire not being delivered into place or the wire feeding rod retracting and pulling back the flat wire after being delivered into place, resulting in inconsistent wire feeding length. Utility Model Content

[0005] The purpose of the utility model is to provide a nailing machine with stable wire feeding to solve the instability of the machine head using a cylinder-type wire clamping wire feeding proposed in the above-mentioned background technology.
