Technical Field

[0001] This utility model relates to the field of plywood drying technology, specifically a plywood hot-press drying rack. Background Technology

[0002] Plywood is a three- or multi-layered sheet material made by rotary cutting logs into veneers or slicing timber into thin sheets and then gluing them together with adhesives. It usually uses an odd number of veneer layers and glues the adjacent veneer layers with the fiber directions perpendicular to each other.

[0003] According to announcement number CN222697463U, a plywood hot-press drying rack includes a base plate, a movable fixing component on one side of the base plate, a drying board fixedly connected to one side of the base plate, and a drying adjustment component fixedly connected to one side of the drying board. This utility model has the following advantages and effects: The movable fixing component allows the drying rack to be moved and fixed in a suitable position, solving the problem of manual handling when the drying rack needs to be adjusted, thus improving its flexibility. The drying adjustment component allows the drying rack to be adjusted to accommodate plywood of different sizes and thicknesses, solving the problem of the drying rack being unable to dry plywood of different sizes and thicknesses, thus improving its adaptability.

[0004] The above-mentioned device can dry plywood of different sizes and thicknesses, and has a certain degree of practicality. According to the instruction manual and the attached drawings, when drying plywood of different thicknesses, it is necessary to rotate the adjustment disc to adjust multiple sets of movable plates. Repeatedly rotating the adjustment disc to adjust makes it relatively time-consuming to use. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that the above-mentioned device can dry plywood of different sizes and thicknesses and has certain practicality. According to the description and drawings, when drying plywood of different thicknesses, it is necessary to rotate the adjustment plate to adjust multiple sets of movable plates. Repeatedly rotating the adjustment plate to adjust causes a time-consuming problem. Therefore, this utility model provides a plywood hot-press drying rack.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a plywood hot-press drying rack, comprising a drying rack body, drying boards for drying are symmetrically fixedly installed at both ends of the drying rack body, movable plates are symmetrically and evenly slidably connected to the top of the drying boards, a groove is opened at one end of the drying rack body, a sliding plate is slidably connected inside the groove, a symmetrical oblique groove is symmetrically opened through one end of the sliding plate, the oblique grooves are symmetrically arranged in the middle and opposite in direction, a connecting shaft is fixedly installed at one end of the movable plate, and the connecting shaft is adapted to the oblique groove, a through hole is opened at the top of the groove, a lifting plate is slidably connected to the top of the drying rack body, and the lifting plate is fixedly installed through the through hole and the sliding plate, and a square groove is opened at the bottom of the drying rack body for the sliding plate to slide.

[0007] As a further embodiment of this utility model: a cavity is provided inside the through hole, and a limit block is slidably connected inside the cavity; a limit groove is uniformly and symmetrically provided at one end of the lifting plate, and the limit groove is adapted to the limit block; a reset spring is fixedly installed inside the cavity, and one end of the reset spring is fixedly installed with the limit block.

[0008] As a further improvement of this utility model: a sliding groove is opened at the top of the cavity, and a connecting rod is slidably connected inside the sliding groove. One end of the connecting rod passes through the sliding groove and is fixedly installed with the limiting block.

[0009] As a further improvement of this utility model, one end of the lifting plate is provided with an adjustable scale.

[0010] As a further embodiment of this utility model: sliding blocks one that slide with the groove are symmetrically fixedly installed at both ends of the sliding plate, and sliding blocks two that slide with the drying board are symmetrically fixedly installed at the bottom end of the movable plate.

[0011] As a further improvement of this utility model: a support plate is provided directly below the drying rack body, a limiting shell is fixedly installed at the top of the support plate, and a limiting rod is provided inside the limiting shell, with the top of the limiting rod fixedly installed at the bottom of the drying rack body.

[0012] As a further improvement of this utility model, the bottom end of the support plate is symmetrically and rotatably connected with self-locking casters for movement.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention releases the locking block of the lifting plate by pulling the connecting rod, and then pushing the lifting plate causes the sliding plate to slide. The cooperation between the inclined groove and the connecting shaft allows for synchronous adjustment of the spacing between the movable plates. This eliminates the need for cumbersome multi-step operations, simplifies the process, saves adjustment time, and improves work efficiency.

[0015] Meanwhile, the sliding block and the groove, the movable plate and the drying plate slide together to ensure that the adjustment process is smooth and stable, and can accurately adapt to the drying needs of plywood of different thicknesses.

[0016] After adjustment, the connecting rod is released, and the spring force of the reset spring automatically pushes the limit block into the limit groove of the lifting plate, achieving quick locking and preventing the movable plate from shifting due to external force during the drying process. At the same time, the scale on the lifting plate intuitively displays the adjustment value, assisting the operator in accurately controlling the distance between the movable plates and ensuring that plywood of different thicknesses can be stably supported, thus improving the accuracy of adjustment.

Movable plates 3 are symmetrically and evenly slidably connected to the top of the drying boards 2. A groove 4 is opened at one end of the drying rack body 1. A sliding plate 6 is slidably connected inside the groove 4. An oblique groove 8 is symmetrically opened through one end of the sliding plate 6. The oblique grooves 8 are symmetrically arranged in the middle and opposite in direction. A connecting shaft 9 is fixedly installed at one end of the movable plate 3, and the connecting shaft 9 is adapted to the oblique groove 8. A through hole 5 is opened at the top of the groove 4. A lifting plate 7 is slidably connected to the top of the drying rack body 1, and the lifting plate 7 is fixedly installed through the through hole 5 and the sliding plate 6. A square groove 12 for the sliding plate 6 to slide is opened at the bottom of the drying rack body 1.

[0026] The above scheme is adopted: the sliding plate 6 is made of PA66+30%GF material, the connecting shaft 9 is stainless steel and is interference-fitted with the movable plate 3, the edges of the through hole 5 are rounded, the lifting plate 7 is made of PP+20% talc powder (thickness 3mm) and is clearance-fitted with the through hole 5, the square groove 12 serves as the sliding space for the sliding plate 6, and an EPDM buffer block is set inside. When the lifting plate 7 moves vertically, the inclined groove 8 converts the linear motion into the sliding of the movable plate through the connecting shaft 9. The inclination angle of the inclined groove 8 at one end of the sliding plate 6 is set so that the distance between two adjacent movable plates 3 is the same during the movement of the sliding plate 6, and the distance between the movable plates 3 is adjusted.

[0027] Reference Figures 1 to 5The through hole 5 has a cavity 13 inside, and a limit block 14 is slidably connected inside the cavity 13. The lifting plate 7 has a limit groove 18 evenly and symmetrically opened at one end, and the limit groove 18 is adapted to the limit block 14. A reset spring 15 is fixedly installed inside the cavity 13, and one end of the reset spring 15 is fixedly installed to the limit block 14. A sliding groove hole 16 is opened at the top of the cavity 13, and a connecting rod 17 is slidably connected inside the sliding groove hole 16. One end of the connecting rod 17 passes through the sliding groove hole 16 and is fixedly installed to the limit block 14.

[0028] Using the above scheme: the cavity 13 inside the through hole 5 is made of aluminum alloy profile, the limiting block 14 is made of 45# steel and is clearance-fitted with the cavity 13, the return spring 15 is made of steel to provide thrust, the connecting rod 17 inside the sliding slot 16 is made of stainless steel and is clearance-fitted with the sliding slot 16, the limiting groove 18 of the lifting plate 7 and the limiting block 14 form a wedge lock, pulling the connecting rod 17 causes the limiting block 14 to compress the return spring 15 and disengage from the limiting groove 18, and the lifting plate 7 can move freely; after being released, the return spring 15 pushes the limiting block 14 to be inserted into the limiting groove 18.

[0029] Reference Figures 1 to 5 One end of the lifting plate 7 is equipped with an adjustable scale 19;

[0030] The above solution allows users to intuitively obtain the adjustment distance when adjusting the spacing of the movable plate 3 using the scale 19, thus achieving positioning.

[0031] Reference Figures 1 to 5 The sliding plate 6 has sliding blocks 10 fixedly installed at both ends to slide with the groove 4, and the movable plate 3 has sliding blocks 11 fixedly installed at the bottom end to slide with the drying plate 2.

[0032] The above scheme is adopted: the sliding blocks 10 at both ends of the sliding plate 6 are made of POM material and are fixed to the sliding plate 6 by stainless steel screws, forming a clearance fit with the groove 4. The sliding block 1 has a built-in graphite lubricating strip. The sliding block 2 11 at the bottom of the movable plate 3 is made of PA66+15%PTFE material and forms a fit with the guide rail of the drying plate 2 (PP+30%GF). The sliding block 2 11 adopts a dovetail groove structure to prevent derailment, and an EPDM buffer pad is provided at the end of the stroke.

[0033] Reference Figures 1 to 5 A support plate 20 is provided directly below the main body 1 of the drying rack. A limiting shell 21 is fixedly installed at the top of the support plate 20, and a limiting rod 22 is provided inside the limiting shell 21. The top of the limiting rod 22 is fixedly installed at the bottom of the main body 1 of the drying rack. A self-locking universal wheel 23 is symmetrically rotatably connected to the bottom of the support plate 20 for movement.

[0034] The above-mentioned scheme is adopted: the limiting shell 21 and the limiting rod 22 are prior art referenced in the prior art documents and are not described in detail in this application. The limiting shell 21 is equipped with a motor. The self-locking universal wheel 23 at the bottom of the support plate 20 is model WJ-50B, with PA66+20% glass fiber wheel frame and wheel body made of high elastic TPR material. The self-locking mechanism adopts a foot pedal double brake design, and the brake block is made of wear-resistant rubber.

[0035] The working principle of this utility model is as follows: During adjustment, pulling the connecting rod 17 causes the limiting block 14 to slide within the cavity 13 and compress the reset spring 15. The limiting block 14 disengages from the limiting groove 18 of the lifting plate 7, releasing the lock. At this time, pushing the lifting plate 7 causes the sliding plate 6 within the groove 4 to slide through the through hole 5. The sliding blocks 10 at both ends of the sliding plate 6 slide smoothly within the groove 4. Since the sliding plate 6 has a through-hole with oblique grooves 8 that are symmetrical in the middle and opposite in direction, the connecting shaft 9 at one end of the movable plate 3 is adapted to the oblique groove 8. When sliding... When the plate 6 slides, the inclined groove 8 forces the connecting shaft 9 to drive the movable plate 3 to slide on the drying plate 2, so as to realize the synchronous expansion or contraction of the distance between the movable plates 3, adapting to the drying needs of plywood of different thicknesses, reducing the time-consuming use of the adjustment by the staff by rotating the adjustment plate. After adjusting to the appropriate distance, the connecting rod 17 is released. Under the elastic force of the return spring 15, the limit block 14 is inserted into the limit groove 18 at the corresponding position of the lifting plate 7 to complete the limit fixation. At the same time, the scale 19 at one end of the lifting plate 7 assists in positioning to ensure the accurate distance between the movable plates 3.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
