Problems solved by technology

[0002] At present, in the production process of multi-layer plywood, vertical veneer is a necessary raw material for the mechanical structure of plywood. Due to the influence of fast-growing forest timber diameter and material utilization rate, it is impossible to produce a complete vertical veneer that meets the size requirements of plywood. , traditional veneer longitudinal butt joint equipment generally has problems such as low production efficiency, automatic splicing cannot be realized, poor splicing effect (such as uneven splicing gaps, overlapping seams), and splicing methods that do not conform to the mechanical structure of plywood, which seriously affect the composite The automation process of plywood production restricts the development of plywood enterprises and the improvement of product quality
[0003] After retrieval, the application publication number is CN 110480767 A, a veneer vertical gluing machine, including main frame, tooth cutting device, tooth cutting transmission device, tooth connection transmission device, board output transmission device, splint moving device, glue making device 1. The gear connection device is provided with four down-pressing cooling pipes and four supporting cooling pipes, but the following disadvantages generally exist: 1) The splint moving device drives the plates behind the comb teeth to carry out rigid docking, and the stability of the tooth connection is not enough. The interface is easy to break; 2) Cooling through the cooling rod, the contact surface is line contact, and the cooling and pressing effect is not good

Description

Technical field [0001] The invention belongs to the technical field of wood processing, and particularly relates to a veneer continuous tooth splicing machine. Background technique [0002] At present, in the production process of multi-layer plywood, vertical veneer is a necessary raw material for the mechanical structure of plywood. Affected by the size of fast-growing forest wood and material utilization rate, it is impossible to produce integrated vertical veneer that meets the size requirements of plywood. , Traditional veneer vertical butting equipment generally has low production efficiency, cannot realize automatic splicing, poor splicing effects (such as uneven splicing gaps, staggered overlap), and splicing methods that do not conform to the mechanical structure of plywood, which seriously affect the composite The process of automatic board production has restricted the development of plywood enterprises and the improvement of product quality. [0003] After searching, t...
