Problems solved by technology

[0005] The technical problem to be solved by the present invention is to solve the problem that the existing hot press still requires the operator to manually carry the veneer, the position and time of the heat source are difficult to accurately control when performing hot pressing, and manual operation is required in the production of overlapping joints of veneer slopes. Complicated, low degree of automation, resulting in manpower and time-consuming, low production efficiency, poor product quality, waste of resources

Embodiment 2

[0048] like Image 6 As shown in the figure, the veneer lengthening system provided in the second embodiment of the present invention includes a first conveyor belt 4, a second conveyor belt 5, and the roller pressing heat press as described in the above-mentioned first embodiment. The first conveyor belt 4 is arranged on the The input end of the veneer of the roll pressing machine, the second conveyor belt 5 is arranged at the output end of the veneer of the roll pressing machine, and the first conveyor belt 4 includes the synchronous parallel upper and lower inclined grinding surface conveyor belts. There is an upper narrow belt sander above the side of the upper oblique grinding surface conveyor belt close to the lower oblique grinding surface conveyor belt to obliquely grind the first veneer to form an upward slope; the lower oblique grinding surface conveyor belt A lower narrow belt sander is arranged below the side of the conveyor belt close to the upper oblique grinding...

Embodiment 3

[0053] The third embodiment of the present invention provides a single-board extension method based on the single-board extension system in the second embodiment, including the following steps:

[0054] S1. Place the first veneer and the second veneer on the upper and lower oblique grinding surface conveyor belts along the grain, respectively;

[0055] S2. The upper narrow-band sander obliquely grinds the end of the first veneer close to the second veneer to form an upward slope, and the lower narrow-band sander obliquely grinds the end of the second veneer close to the first veneer to form a downward slope. bevel;

[0056] S3. The pressure glue injector applies glue to the slope of the first veneer;

[0057] S4. The adsorption conveyor belt picks up the second veneer and runs synchronously to the input end of the veneer with the upper inclined grinding surface conveyor belt; the servo cylinder pushes the adsorption conveyor belt to move laterally to the corresponding top of ...

Abstract

The invention relates to the technical field of veneer manufacturing, in particular to a rolling hot press. The rolling hot press comprises a hot pressing roller and a transmission device; the transmission device comprises a driving roller and a driven roller, the driven roller is located at the input end of a veneer, the driving roller is located at the output end of the single veneer, and the driving roller and the driven roller are connected through a rolling belt closed in a loop back mode; the hot pressing roller is located between the driving roller and the driven roller, the outer side of the rolling belt makes contact with and is tangent to the peripheral face of the hot pressing roller to form a hot pressing section to drive the hot pressing roller to rotate in the circumferential direction, and the veneer is heated and combined in a pressurized mode on the hot pressing section. Veneers are continuously and automatically input into and output of the hot press, the hot press can work continuously, labor is saved, work time is shortened, working efficiency and automatic performance are improved, joint completeness and accuracy can be ensured, and veneer joint quality is improved.

Description

technical field [0001] The invention relates to the technical field of plywood manufacturing, in particular to a rolling hot press, a veneer lengthening system and method. Background technique [0002] At present, in the production of plywood, it is generally produced by the process of rotary cutting veneer gluing, artificial assembling, pre-pressing and hot-pressing. The number of positions of the combined veneer, the low efficiency of gluing and assembling, and the defects such as separation and lamination are easy to occur in the process of assembling, handling and pre-pressing, resulting in the deterioration of the quality of the plywood. Therefore, veneer integration plays an important role in improving production efficiency, improving wood utilization, and ensuring the quality of plywood. [0003] Longitudinal lengthening methods of veneers include flat, toothed and lap joints. Practice has proved that slanted lap joint is the best longitudinal veneer lengthening meth...
