Description

Technical Field

[0001] The utility model relates to the technical field of double-door processing equipment, in particular to a belt feeding mechanism. Background Art

[0002] In the processing of double-doors, the delivery and gluing of edge banding are two key steps, which are used to add edge banding materials to the edges of door panels and ensure their firm bonding.

[0003] (1) Delivery of edge banding:

[0004] When processing double-doors, edge banding (PVC, ABS, wood grain, aluminum alloy and other materials) is usually used to cover the edge of the door panel to increase the aesthetics, durability and waterproofness. The edge banding is usually stored in a roll in a roll device, and is gradually transported to the processing area during the processing process through the action of rollers or cylinders. During the transportation process, the edge banding needs to be accurately positioned and clamped to ensure that it is in a stable position during the processing and will not deviate or shift.

[0005] (2) Glue coating:

[0006] After being delivered to the processing area, the edge banding needs to be coated with glue to ensure that it is firmly and reliably bonded to the edge of the door panel. The edge of the edge banding is coated with a glue coating system. The glue coating system usually includes a glue coating roller, nozzle or brush to ensure that the glue is evenly coated on the edge of the edge banding. The type of glue used for gluing usually varies depending on the material and processing requirements of the edge banding. Common types of glue include hot melt glue, cold glue or double-sided tape.

[0007] However, the prior art has great deficiencies in the above-mentioned two key processing steps. On the one hand, during the conveying process of the straight-edge edge banding, the edge banding will move in the vertical direction along the outer wall of the driving wheel, thereby making it impossible for the edge banding to stably fit the outer wall of the driving wheel for force-driven movement, affecting the conveying stability of the edge banding and the edge banding processing effect; on the other hand, during the gluing process, the mother-and-child wooden door machine needs to apply glue on the edge banding. When the edge banding is stained with high-temperature glue, its own weight increases. Due to the high temperature, the edge banding will be heated and bent, so that there is a certain distance in the process of passing through the gluing shaft to reach the straight-edge pressing mechanism. When the edge banding is conveyed from the gluing shaft to the pressing shaft, it will warp or bend, which also seriously affects the edge banding processing effect. Utility Model Content

[0008] In view of this, the technical problem to be solved by the utility model is: how to provide a belt feeding mechanism to improve the conveying stability of the edge banding belt along the height direction of the pressing wheel during the conveying process and at the same time improve the supporting performance of the edge banding belt when it is conveyed from the gluing shaft to the pressing wheel.

[0011] The paddle unit comprises a seat, a pressing sleeve, a first paddle, a second paddle, a paddle shaft and a glue coating shaft, wherein the first paddle and the second paddle are arranged on the paddle shaft, wherein two second paddles are respectively arranged above and below one of the first paddles, the outer edge of the first paddle is a straight line, and the outer edge of the second paddle is a wave shape;
