Description

Technical Field

[0001] This utility model relates to the field of paving machine technology, specifically a directional homogeneous core layer paving head. Background Technology

[0002] Particleboard is the most widely used engineered wood product. It can effectively replace logs and sawn timber in construction, decoration, furniture, flooring manufacturing, and other fields. It saves precious natural forest timber, improves resource utilization, and meets the demand for wood products in economic and social development.

[0003] Particleboard laying machines are key equipment in particleboard production. They evenly spread shavings of a certain density into board blanks of a specific size and specification. The performance of the particleboard laying machine directly affects the laying quality of the particleboard blanks, which in turn affects the physical and mechanical properties of the particleboard. The development of particleboard laying machines has evolved from mechanical laying machines to air-jet laying machines and graded laying machines. The laying head is an important component of the laying machine. Currently, most laying heads in existing technologies are designed for the laying needs of a single product. For example, the laying head for producing ordinary particleboard and the laying head for producing high-strength particleboard have different structures. The laying head for producing high-strength particleboard has a combing disc structure inside. Therefore, the laying heads for the two products are not interchangeable. When changing the product being produced, the entire laying head needs to be disassembled and replaced, which is time-consuming and labor-intensive, affecting production efficiency. Purchasing multiple laying heads also increases equipment costs.

[0004] Therefore, the inventors sought to solve the problem of designing a device that could switch paving modes, be suitable for production of various specifications, reduce equipment costs, and improve production efficiency. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this invention is to provide a directional homogeneous core layer laying head that can switch laying modes, is suitable for production of various specifications, reduces equipment costs, and improves production efficiency.

[0011] Furthermore, when the two lower paving structures are in contact, the connecting rod does not contact the end of the chute.

[0012] Furthermore, the combing discs arranged on the inner sides of the two lower paving structures rotate in opposite directions.

[0013] Furthermore, the lower paving structure has threaded holes at its ends.

[0014] The beneficial effects of this utility model device are:

[0015] 1. Based on the original structure of the paving head, this utility model adds a lower paving structure that can be moved to switch usage states when not in use.
