[0002] With increasing market demand for wood products, wood processing plants urgently need to improve production efficiency. Traditional air-drying or inefficient drying methods often require a long time and cannot meet the needs of large-scale production. Furthermore, the degree of glue curing directly affects the bond strength of the wood. Traditional drying methods can easily lead to incomplete or uneven curing of the glue, affecting the quality of the finished product. To ensure higher-quality wood products, the development of efficient and uniform drying equipment is crucial.

[0003] After searching, the patent number CN 222225091 U is a single board conveying clamp, which discloses a support table, the bottom of the support table is fixedly connected to a support leg, the top of the support table is fixedly connected to a support frame, the top of the support frame is fixedly connected to a stabilizing frame, a No. 1 guide mechanism is provided inside one side of the stabilizing frame, a No. 2 guide mechanism is provided on the top of one side of the stabilizing frame, a transmission mechanism is provided on the top of the other side of the stabilizing frame, a chain is engaged with the outside of the transmission mechanism, and a support rod is fixedly connected to the outside of the chain.

[0015] In a second aspect, a control method for a continuous single-board baking chain device is provided, comprising the following steps:

[0016] S1: During drying, first place the veneer bodies to be dried one by one from the loading end of the conveyor rack between the two clamping rods of the V-shaped clamp, and place the end of the veneer body against the bottom of the groove of the grooved support plate and in the center;

[0017] S2: Then slowly press the single board body toward the connecting belt. At this time, the double-sided rack on the back of the grooved support plate drives the two half gears to rotate in opposite directions at the same time. Continue to push the single board body until the two right-angled tooth blocks at the end of the double-sided rack are locked by the stop block at the end of the sliding rod. At this time, the two clamping rods in the V-shaped clamp complete the engagement with the single board body.

[0018] S3: The engaged veneer body will move forward along with the connecting belt and enter the drying hood. After the veneer body passes through a series of dehumidification in the drying hood, it will reach the discharge end. At this time, the unlocking magnet will attract the passing bar magnet, and then the stop block at the end of the sliding rod will lose its restriction on the right-angle tooth block. Then, under the action of the two tightening springs, the V-shaped clamps will open together to release the dried veneer body.

[0019] The beneficial effects of the present invention are:

[0020] 1. By using a grooved support plate arranged between the two clamping rods in the V-shaped clamp and a double-sided rack inserted between the two half gears, when the veneer body to be dried needs to be clamped, it is only necessary to place the end of the veneer body against the bottom of the groove of the grooved support plate, and then continue to push it toward the connecting belt to close the two open clamping rods of the V-shaped clamp, completing the clamping of the veneer body. Since the upper surface of the grooved support plate is a flat structure, it can prevent the edge of the veneer body from being clamped and notched.

[0021] 2. The guide sockets and guide slide bars ensure that when the trough-type pallet is squeezed by the single board body, the double-sided rack can be inserted directly between the two half gears in a state perpendicular to the surface of the flat tube bar, and then the two clamping rods in the V-shaped clamp rotate in the same range, so that the clamped single board body remains perpendicular to the upper surface of the flat tube bar.

[0022] 3. Through the setting of the tightening spring and the sliding lever, the grooved support plate has the function of automatic recovery after being pressed, and when the clamping mechanism runs to the discharge end, the sliding lever will release the locking restriction of the right-angle tooth block on the side of the double-sided rack under the action of the unlocking magnet, and then the V-shaped clamps will be opened.

[0023] 4. The set straightening mechanism can prevent the clamping plate mechanism from tilting and tilting as a whole, and ensure that the distance between two adjacent single plate bodies in the working section is the same everywhere. BRIEF DESCRIPTION OF THE DRAWINGS
