Description

Technical Field

[0001] This utility model belongs to the field of wooden pallet processing technology, specifically relating to a sanding fixture for wooden pallet processing. Background Technology

[0002] Wooden pallets are essential tools in logistics and transportation, and the smoothness of their surface directly affects the safety and lifespan of goods. Currently, the sanding process for wooden pallets mainly relies on manual operation, where workers use hand sandpaper or sanders to sand the wood surface. However, this traditional sanding method has many drawbacks, severely restricting the efficiency and quality of wooden pallet processing.

[0003] Manual sanding is slow and cannot meet the demands of modern large-scale production, becoming a key factor restricting production efficiency. Furthermore, manual operation makes it difficult to precisely control the sanding force and uniformity, easily leading to uneven sanding, rough surfaces, and burrs, affecting the appearance and lifespan of wooden pallets. Secondly, prolonged repetitive manual work can easily cause worker fatigue, increasing the risk of operational errors and posing certain safety hazards. Utility Model Content

[0004] The purpose of this invention is to provide a sanding fixture for processing wooden pallets, which can solve the above-mentioned technical problems.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] This utility model provides a sanding fixture for processing wooden pallets, including a base and a side sanding assembly disposed on the base. Two side plates are respectively disposed on both sides of the base, and a support plate is disposed between the two side plates and located above the side sanding assembly. Four centrally symmetrical inner clamping plates are disposed on the support plate for clamping the wooden pallet. A top surface sanding assembly is disposed above the support plate.

[0007] The side grinding assembly includes a side sliding plate located below the support plate, two sets of side frame plates, two sets of buffer springs, and two side grinding rollers. Two side slide rails are slidably installed on both sides of the sliding plate, and the side slide rails are arranged between the two side plates. A push screw located below the support plate is threadedly matched on the side sliding plate. The push screw is rotatably mounted on the two side plates. A push motor is installed on the side of one of the side plates to drive the push screw to rotate.

[0008] Mounting plates are provided on both sides of the side sliding plate. Two sliding rods are provided between the two sets of side frame plates. The two sets of side frames are detachably mounted on the two mounting plates. Elastic sliding plates are provided inside the two sets of side frames. Two sets of buffer springs are sleeved on the sliding rods. The buffer springs are located between the elastic sliding plates and the inner side of the frames. The elastic sliding plates are slidably mounted on the two sliding rods. A rotating shaft is rotatably mounted on the elastic sliding plates. A side grinding roller is detachably mounted on the upper side of the rotating shaft. A side drive motor is mounted on the bottom surface of the elastic sliding plates to drive the rotating shaft to rotate.

[0009] Using the aforementioned sanding fixture for wooden pallet processing, the wooden pallet is placed on the inner sleeve plate of the support plate. Then, the controller starts the push motor, which drives the push screw to rotate and move the side sanding assembly. Simultaneously, the side drive motor on the side sanding assembly is started, driving the side sanding roller to rotate. In this way, the rotating side sanding roller can move and sand the sides of the wooden pallet. When the side sanding assembly moves to the side plate position, the wooden pallet can be lifted and rotated to sand the other two sides.

[0010] Next, the electric lifting push rod is retracted, and the sanding drive motor on the top sanding assembly is activated, causing the sanding drive motor to rotate the top sanding roller. Simultaneously, the top sanding assembly descends to the upper surface of the wooden pallet. Then, the top drive motor is activated, driving the drive screw to rotate, which in turn moves the top surface translation plate and the top sanding roller. In this way, the rotating top sanding roller can move and sand the upper surface of the wooden pallet, achieving a comprehensive sanding effect.

[0011] Preferably, the top surface grinding assembly includes two inner sleeve plates, a translation support member, and a movable grinding member. The two inner sleeve plates are slidably fitted into two sleeve seat members, and both sleeve seat members are installed on the side of another side plate. A connecting plate is provided on the upper side of the two inner sleeve plates, the translation support member is provided on the connecting plate, and the movable grinding member is provided on the translation support member.

[0012] Preferably, the translation support includes a top frame plate, two top slide rails are provided between the two top frame plates, a drive screw is rotatably mounted on the top frame plate, and a top drive motor is mounted on the side of the top frame to drive the drive screw to rotate.

[0013] Preferably, the movable grinding component includes a top surface translation plate slidably mounted on a top surface slide rail rod. The top surface translation plate is threadedly engaged with a drive screw. A top surface grinding roller is provided below the top surface translation plate. Stabilizing plates are respectively installed on both sides of the top surface translation plate. The top surface grinding roller is rotatably mounted on the two stabilizing plates. A grinding drive motor is installed on the side of one of the stabilizing plates to drive the top surface grinding roller to rotate.

[0014] Preferably, the bottom surface of the connecting plate is provided with a lifting electric push rod, which is installed on the side of another side plate.

[0015] The beneficial effects are:

[0016] This invention utilizes a sliding screw, a sliding motor, a side sanding assembly, and a top sanding assembly in combination. The side sanding assembly, driven by the sliding screw, can perform movable sanding on the sides of the wooden pallet, while the top sanding assembly can perform movable sanding on the top surface of the wooden pallet. This improves the sanding efficiency of the wooden pallet, ensures a uniform sanding effect, and prevents the risk of human error. Attached Figure Description

[0025] Mounting plates 22 are respectively provided on both sides of the side sliding plate 21. Two sliding rods 23 are provided between the two sets of side frame plates 24. The two sets of side frames are detachably mounted on the two mounting plates 22. Elastic sliding plates 25 are respectively provided in the two sets of side frames. Two sets of buffer springs 26 are sleeved on the sliding rods 23. The buffer springs 26 are located between the elastic sliding plate 25 and the inner side of the frame. The elastic sliding plate 25 is slidably mounted on the two sliding rods 23. A rotating shaft 27 is rotatably mounted on the elastic sliding plate 25. A side grinding roller 28 is detachably mounted on the upper side of the rotating shaft 27. A side drive motor 29 is mounted on the bottom surface of the elastic sliding plate 25 to drive the rotating shaft 27 to rotate.

[0026] As an optional implementation, the top surface grinding assembly 4 includes two inner sleeve plates 41, a translational support member, and a movable grinding member. The two inner sleeve plates 41 are slidably fitted into two sleeve seat 3s, and the two sleeve seat 3s are installed on the side of another side plate 6. A connecting plate 42 is provided on the upper side of the two inner sleeve plates 41, the translational support member is provided on the connecting plate 42, and the movable grinding member is provided on the translational support member. This arrangement allows the inner sleeve plates 41 to rely on the sliding connection with the sleeve seat 3, which can improve the stability of the top surface grinding assembly 4 during lifting and lowering operations.

[0027] See attached document Figure 2 and attached Figure 3The translation support includes a top frame plate 44, two top slide rail rods 43 are arranged between the two top frame plates 44, a drive screw 45 is rotatably mounted on the top frame plate 44, and a top drive motor 46 is mounted on the side of the top frame to drive the drive screw 45 to rotate.
