Description

Technical Field

[0001] This utility model is a rough planing device for toys, belonging to the field of wooden toy processing. Background Technology

[0002] In the production process of wooden toys, rough planing is a crucial step in the initial treatment of the wood surface. This process, through the cutting action of the planer blades, thoroughly removes bark, burrs, uneven textures, and excess material from the wood surface, creating a relatively flat and smooth base surface. This paves the way for subsequent fine planing, sanding, carving, painting, and other fine processing steps. A rough planer is a commonly used tool for this process. Its working principle involves a motor driving a high-speed rotation of the planer blade assembly. The rotating blade assembly works in conjunction with two base plates on the machine body—during operation, the base plates move smoothly along the wood surface, and the planer blades in the assembly cut the wood accordingly.

[0003] Traditional rough planers use a flat base plate. While this design maintains stability when processing regular, straight wood, it reveals significant drawbacks when dealing with curved, convex wood. Because the flat surface of the base plate cannot fully align with the curved surface of the wood, the contact area is greatly reduced. During the movement of the rough planer, this limited contact area fails to provide sufficient support, easily leading to wobbling and shifting. This not only affects the uniformity of cutting and surface smoothness but also increases operational difficulty and overall stability, making it unsuitable for rough processing curved, convex wood. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a toy rough planing device to solve the problems mentioned in the background technology. This utility model solves the problem that the traditional flat base plate is not enough to support the arc-shaped protruding wood.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a toy rough planer, comprising:

[0006] The outer casing has a first base plate and a second base plate installed at the bottom, with a gap between the first base plate and the second base plate, and a horizontal hole is provided at the end of the outer casing near the second base plate;

[0007] The rough planer is installed inside the housing;

[0008] A crossbar is inserted into a horizontal hole, and the crossbar is kept in a fixed relative position with the outer shell by a positioning screw. Both ends of the crossbar are provided with notches, and two strip-shaped openings are provided on the outer surface of the crossbar, with the two strip-shaped openings located between the two notches.

[0009] Two swing plates are provided, and the two swing plates are respectively rotatably installed in two notches. An elongated oval opening is provided at the upper part of one side of each swing plate.

[0010] Two limiting plates are provided, and the two limiting plates are rotatably installed in two strip-shaped openings respectively. The end of the limiting plate away from the crossbar is connected to the swing plate through a fastener formed by a limiting screw and a nut. One end of the limiting screw passes through the elongated oval opening.

[0011] The rollers are mounted on the lower end of the swing plate.

[0012] Furthermore, the rough planer includes:

[0013] A planer blade assembly is rotatably mounted inside the housing, and the planer blade assembly is disposed between the first base plate and the second base plate;

[0014] The motor is installed inside the casing;

[0015] A small pulley is installed at one end of the planer blade assembly;

[0016] A large pulley is mounted on the output shaft of the motor;

[0017] A transmission belt is used, and the small pulley is connected to the large pulley via the transmission belt.

[0018] Furthermore, the transmission belt is disposed on the outside of the housing, and a protective cover is provided on the outside of the transmission belt. The protective cover is connected to the housing by screws. A heat dissipation cover is installed on the side of the housing facing away from the protective cover, and multiple heat dissipation holes are evenly opened on the outer surface of the heat dissipation cover.

[0019] Furthermore, a positioning hole is provided at the middle of the outer surface of the crossbar, and a positioning screw is threaded onto one side of the outer shell, with one end of the positioning screw inserted into the positioning hole.

[0020] Furthermore, both ends of the crossbar are provided with first screw holes communicating with the notches, and the swing plates in the notches at both ends of the crossbar are provided with first shaft holes that cooperate with the first screw holes. The first screw holes are internally threaded with first screws, and one end of the first screw is inserted into the first shaft hole.

[0021] Furthermore, two second screw holes communicating with the slots are opened on the outer surface of the crossbar. A second shaft hole is opened on the limiting plate in each of the two slots on the crossbar. A second screw is threaded into the second screw hole, and one end of the second screw is inserted into the second shaft hole.

[0022] Furthermore, the limiting plate has a through hole at one end near the swing plate, and the limiting screw is threaded with a nut after passing through the channel formed by the through hole and the elongated opening.

[0023] Furthermore, a gripping handle is installed on the upper part of the outer surface of the housing, and the gripping handle and the housing are integrally formed.

[0024] The beneficial effects of this utility model are:

[0025] 1. By setting rotatable swing plates at both ends of the crossbar, and cooperating with the rollers at the lower end of the swing plates, the relative position of the limiting plate and the swing plate is adjusted when the equipment is processing curved and protruding wood. At this time, the relative position of the swing plates changes, allowing the rollers to adapt to the curved surface of the wood and adjust the angle accordingly. The structure formed by the two rollers, the first base plate and the second base plate increases the contact area with the wood, reduces shaking, improves operational stability, and solves the problem of insufficient support for curved and protruding wood by traditional flat base plates.

[0026] 2. The rotatable connection between the swing plate and the crossbar, and the adjustable connection between the limit plate and the swing plate, with the help of the elongated opening and the limit screw, allow the swing angle to be flexibly adjusted according to the curvature of the wood. This can adapt to both curved and convex wood with different curvatures and flat wood, thus broadening the applicability of the equipment.

[0027] 3. Use the first screw to connect the swing plate to the crossbar, and use the second screw to connect the limit plate to the crossbar. When the roller is not needed, remove the first and second screws to separate the swing plate, limit plate and crossbar, and then remove the positioning screws to facilitate the separation of the crossbar from the housing. No major changes need to be made to the appearance of the original equipment. Attached Figure Description

[0044] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0045] Please see Figures 1-4 This utility model provides a technical solution: a toy rough planer, including a shell 1, a gripper 11 installed on the upper part of the outer surface of the shell 1, the gripper 11 and the shell 1 are integrally formed, a first base plate 12 and a second base plate 13 are installed at the bottom of the shell 1, there is a gap between the first base plate 12 and the second base plate 13, a planer blade assembly 7 is rotatably installed in the shell 1, the planer blade assembly 7 is set between the first base plate 12 and the second base plate 13, a motor 72 is installed in the shell 1, a small pulley 74 is installed at one end of the planer blade assembly 7, a large pulley 73 is installed on the output shaft of the motor 72, the small pulley 74 is connected to the large pulley 73 through a transmission belt 71, the transmission belt 71 is set on the outside of the shell 1, a protective cover 15 is provided on the outside of the transmission belt 71, the protective cover 15 is connected to the shell 1 by screws, a heat sink 14 is installed on the side of the shell 1 away from the protective cover 15, the outer surface of the heat sink 14 is evenly provided with multiple heat dissipation holes, the protective cover 15 achieves the concealment and protection of the transmission belt 71.

[0046] See Figures 1-6A horizontal hole is provided at one end of the outer shell 1 near the second base plate 13. The horizontal bar 3 is inserted into the horizontal hole and the horizontal bar 3 is kept in a fixed relative position with the outer shell 1 by the positioning screw 2. A positioning hole 31 is provided at the middle of the outer surface of the horizontal bar 3. The positioning screw 2 is threadedly connected to one side of the outer shell 1 so that one end of the positioning screw 2 is inserted into the positioning hole 31, thereby limiting the relative position of the horizontal bar 3 and the outer shell 1.

[0047] Both ends of the crossbar 3 have notches 33, and the outer surface of the crossbar 3 has two strip-shaped openings 32, which are located between the two notches 33. Two swing plates 5 are rotatably installed in the two notches 33 respectively. One side of the swing plate 5 has an elongated oval opening 51 at its upper part, and two limiting plates 6 are rotatably installed in the two strip-shaped openings 32 respectively. The end of the limiting plate 6 away from the crossbar 3 is connected to the swing plate 5 by a fastener formed by a limiting screw 8 and a nut 81. The end of the limiting plate 6 near the swing plate 5 has a through hole, and one end of the limiting screw 8 passes through the channel formed by the through hole and the elongated oval opening 51 and is threaded to the nut 81. The roller 4 is rotatably installed at the lower end of the swing plate 5. Rotatable swing plates 5 are assembled at both ends of the crossbar 3, and rollers 4 are installed at the lower end of the swing plates 5. When processing curved and protruding wood, by adjusting the relative position of the limiting plate 6 and the swing plate 5, the angle of the swing plate 5 can be changed, so that the roller 4 can adapt its posture to conform to the curved surface of the wood. At this point, the two rollers 4 together with the original first base plate 12 and second base plate 13 form a multi-point support structure, which greatly increases the contact area with the wood, effectively reduces the shaking of the equipment during movement, significantly improves the operational stability, and completely solves the problem of insufficient support for arc-shaped protruding wood by traditional flat base plates.

[0048] The swing plate 5 is mounted on the crossbar 3 by rotation. The limiting plate 6 and the swing plate 5 are connected by an adjustable structure. The swing angle of the swing plate 5 can be flexibly adjusted by the cooperation of the elongated opening 51 and the limiting screw 8. This design can not only adapt to the curved protruding wood with different curvatures, but also meet the processing needs of flat wood, greatly expanding the application range of the equipment.

[0049] See Figures 1-3 , Figure 5 and Figure 6Both ends of the crossbar 3 have first screw holes communicating with notches 33. The swing plates 5 in the notches 33 at both ends of the crossbar 3 each have first shaft holes that mate with the first screw holes. A first screw 52 is threaded into each of the first screw holes, with one end of the first screw 52 inserted into the first shaft hole. Two second screw holes communicating with slots 32 are opened on the outer surface of the crossbar 3. The limiting plates 6 in the two slots 32 on the crossbar 3 each have second shaft holes. Second screws 61 are threaded into each of the second screw holes, with one end of the second screw 61 inserted into the second shaft hole. The first screw 52 enables the swing plates 5 to rotate with the crossbar 3; the second screws 61 enable the limiting plates 6 to rotate with the crossbar 3. When the rollers 4 are not needed, simply remove the first screws 52 and the second screws 61 to separate the swing plates 5, limiting plates 6, and crossbar 3. Then, remove the positioning screws 2 to easily remove the crossbar 3 from the outer casing 1. The entire disassembly process does not require significant alteration to the original external structure of the equipment, preserving its original main form.
