Description

Technical Field

[0001] This utility model relates to the technical field of engineered wood production equipment, specifically a retractable weighing device for measuring the amount of glue applied to veneer or plywood core. Background Technology

[0002] In the production of engineered wood products, the amount of glue applied to the veneer or plywood core has a significant impact on the performance of the finished product. Excessive or insufficient glue application can lead to problems such as incomplete cold pressing, bubbling during hot pressing, or substandard bonding strength. Therefore, it is necessary to weigh the glue application during production and adjust it to the appropriate range based on the results. Currently, the weighing of glue application in production typically relies on manual operation, where workers lift the veneer for weighing. If weighing is not done manually, the veneer or plywood core is placed directly on the scale, which often results in it touching the ground due to its excessive length or width, affecting measurement accuracy and leading to incorrect judgments. Furthermore, manual weighing may introduce measurement errors, affecting production efficiency and quality stability. Utility Model Content

[0003] To address the shortcomings of the aforementioned technologies, this invention provides a retractable glue application weighing device to better adapt to production needs, reduce manual operation, improve weighing accuracy, and thus optimize glue application control in the production process of engineered wood panels. Through retractable control, the glue application amount of veneers or plywood cores of different lengths and widths can be weighed. Furthermore, all components of the device are made of metal materials through welding. The surfaces of the metal materials are coated with polytetrafluoroethylene (PTFE) to reduce glue adhesion during use and extend the device's service life.

[0008] The telescopic outer rod is a hollow tubular structure that is vertically fixed to the support frame;

[0009] The telescopic inner rod is nested inside the telescopic outer rod and can extend and retract axially;

[0010] A telescopic button is arranged on the side wall of the telescopic outer rod, and is used for locking or releasing the telescopic position of the telescopic inner rod.

[0011] In some embodiments, the telescopic rod is provided with two.

[0012] In some embodiments, the whole surface of the device is provided with a polytetrafluoroethylene (PTFE) coating.

[0017] In some embodiments, the supporting seat is a metal frame structure. BRIEF DESCRIPTION OF DRAWINGS

[0018] Figure 1 A structure diagram of the telescopic glue coating weighing device is provided. DETAILED DESCRIPTION

[0019] Please refer to Figure 1The embodiment provides a scalable glue coating amount weighing device, which comprises a support seat 1 and a scalable rod, the support seat 1 adopts a metal frame structure welded by stainless steel square tubes. The structure not only guarantees the strength and stability of the support seat, but also effectively reduces the overall weight of the device, facilitating movement and operation. A non-slip pad is installed at the bottom of the support seat 1. The non-slip pad is made of rubber material and has a certain roughness on the surface, which can increase the friction between the support seat and the platform scale surface, prevent the support seat from sliding during weighing, and ensure the accuracy of the measurement results. Two scalable rods 2 are fixed vertically on the support seat 1 and arranged in parallel. The outer rod 22 is a hollow tubular structure made of stainless steel with a thickness of 2 mm. This material has good corrosion resistance and strength and can withstand the weight of the plate body without being easily deformed. The inner rod 21 is nested in the outer rod 22 and is also made of stainless steel with a thickness of 2 mm. The surface of the inner rod 21 is finely processed to smoothly expand and contract in the axial direction of the outer rod 22. The expansion button 23 is arranged on the side wall of the outer rod 22 and is a spring type mechanical locking mechanism. When the position of the inner rod 21 needs to be adjusted, the spring is compressed by pressing the expansion button 23, and the inner rod 21 can freely expand and contract. When the expansion button 23 is released, the spring returns to its original position, locking the inner rod 21 in the current position and ensuring that the rod body does not move during weighing.

[0020] The surface of the entire device, including the support seat 1, the scalable rod 2 and all other components, is coated with a polytetrafluoroethylene (PTFE) coating. The PTFE coating has a very low surface friction coefficient and good chemical stability, which can effectively reduce the adhesion of glue solution on the surface of the device. Even after long-term use, the glue solution is difficult to adhere to the surface of the coating, and can be easily cleaned by wiping, greatly prolonging the service life of the device.

[0021] By setting the scalable rod and the positioning groove, the single board or the fine woodworking board core with different lengths and widths can be kept in a suspended state during weighing, avoiding the problem of affecting the measurement accuracy caused by the contact between the plate body and the ground, thereby improving the weighing accuracy of the glue coating amount. Compared with the traditional manual holding weighing or directly placing on the platform scale, the measurement error is effectively reduced, which provides a guarantee for the accurate control of the glue coating amount in the production process.

[0022] The design of the device enables workers to place the plate body on the device and adjust the height of the scalable rod to complete the weighing operation without holding the single board, greatly reducing the labor intensity of workers and improving the production efficiency. At the same time, reducing manual operation also reduces the measurement error caused by human factors, which is conducive to improving the stability of production quality.

[0023] The telescopic function of the telescopic rod enables the device to adapt to the weighing requirements of single boards or plywood cores of different lengths and widths. Whether it is a single board of smaller size or a plywood core of larger size, accurate weighing can be achieved by adjusting the height of the telescopic rod, improving the versatility and applicability of the device and better meeting the diversified needs in the production process of artificial boards.

[0024] The PTFE coating on the surface of the device can effectively prevent the adhesion of glue liquid, reduce the corrosion and damage of the device by the glue liquid, and prolong the service life of the device. Compared with the device without coating, the work of frequent cleaning and maintenance due to the adhesion of glue liquid is reduced, the equipment maintenance cost is reduced, and the continuity and stability of production are improved.

[0025] Usage steps: Place the support seat on the platform scale surface, then embed the uncoated board body into the positioning groove with the bottom end, lean the top end on the telescopic rod, press the telescopic button to adjust the rod height, ensure that the board body is suspended, record the initial total mass M1; embed the measured board body into the positioning groove again after coating, read the total mass M2, and finally calculate the coating amount M=M2-M1.

[0026] Maintenance: Clean the surface of the PTFE coating regularly to remove residual glue liquid; check the spring locking function of the telescopic button to ensure smooth adjustment.
