Description

TECHNICAL FIELD

[0001] The present disclosure relates to a planer, in particular, a curved surface planer capable of planing a three-dimensional shoe upper. BACKGROUND

[0002] A shoe upper is usually made of multiple pieces of material, especially in complex shoe models, multi-level and multi-curved surface splicing technology is often used. However, due to the thickness difference of leather or other materials, the stitching part often appears uneven, wrinkled or raised, and these irregular surface defects will directly affect the appearance of the shoe upper, and even affect the comfort of wearing. Therefore, a hammering machine is often used in the traditional shoemaking process to hammer the shoe upper in order to eliminate wrinkles and smooth the surface, so that the shoe upper meets the quality requirements.

[0003] Due to the characteristics of leather and the three-dimensional structure of the shoe upper, the existing hammering technology is difficult to accurately process the curved surface, especially in specific three-dimensional structure positions such as the shoe heel. When the hammering position involves a curved area such as the shoe heel, the planar planing unit of the commonly used hammering machine will cause poor hammering effect due to the complex three-dimensional curved surface structure of this part, and even new indentations or damage may be caused. Therefore, the existing technology still has certain limitations in processing the flatness of the three-dimensional structure of the shoe upper. CONTENT OF THE INVENTION

[0004] The main purpose of the present disclosure is to solve the problem that the existing technology cannot effectively smooth the target surface when hammering a three-dimensional curved surface because the hammering surface does not match the shape of the target surface. The traditional hammering machine is mainly designed for planar hammering, and when it is applied to shoe uppers or other curved three-dimensional structures, it cannot meet the complex curved surface requirements. Therefore, the present disclosure provides a curved surface planer that can adapt to various curved surface requirements, enhance the processing effect and improve the flatness of the finished product.

[0005] To achieve the above purpose, one embodiment of the present disclosure provides a curved surface planer, which comprises a machine table, a planing mechanism, a cantilever, a displacement mechanism and a swing block.

[0008] In another embodiment of the present disclosure, the displacement unit comprises a positioning column and at least one sliding block, the sliding block is arranged on the top of the positioning column to form a T shape, and the sliding block slides between the two arc-shaped sliding grooves, and the positioning column is fixedly arranged on the top of the rotating block.

[0009] In another embodiment of the present disclosure, after the two pushing units are attached to each other, the bottoms of the two arc-shaped sliding grooves jointly form a displacement channel, the width of the displacement channel is greater than the diameter of the positioning column, the width of the displacement channel is less than the length of the sliding block, and the displacement channel is limited in the sliding range of the displacement unit in the arc-shaped sliding groove.

[0010] In another embodiment of the present disclosure, the surface of the pushing unit corresponding to the swing block is flat.

[0011] In another embodiment of the present disclosure, the leveling mechanism further comprises a stroke adjusting device, and the stroke adjusting device controls the hammering range of the leveling unit.

[0012] In another embodiment of the present disclosure, the material of the swing block is selected from shock-absorbing materials or hard materials.

[0022] In order to more clearly illustrate the core idea of the above-mentioned content, the following provides specific embodiments. Please note that the proportions of the objects in these embodiments are only for enumeration and illustration, and are not drawn according to the actual proportions of the elements. In addition, in order to improve readability, a part of the constituent parts is omitted or is depicted using a phantom line and the like in some drawings.

[0023] Please refer to Figures 1 to 6 An arc surface leveling machine, comprising a machine table 10, a leveling mechanism 20, a cantilever 30, a displacement mechanism 40, and a swing block 50. Through the arc surface leveling machine of the present disclosure, the leveling processing of a three-dimensional arc surface object such as a shoe surface can be realized.

[0024] The leveling mechanism 20 is arranged above the machine table 10, and the leveling mechanism 20 comprises a power source 21 and a leveling unit 22. The leveling unit 22 is driven by the power source 21 to generate a vertical reciprocating leveling action. The cantilever 30 is arranged at one end of the machine table 10, and the other end of the cantilever 30 extends downward relative to the leveling mechanism 20. The displacement mechanism 40 is arranged at the end of the cantilever 30 away from the machine table 10 and below the leveling mechanism 20. The displacement mechanism 40 can generate an arc sliding action along a first direction X. The swing block 50 is arranged at the top of the displacement mechanism 40 and below the leveling unit 22. The top of the swing block 50 has a shaped arc surface 51 corresponding to the arc sliding action. The shaped arc surface 51 is consistent with the surface of the object to be processed.

[0025] Based on the above structure, the leveling unit 22 can be a hammer. When the object to be processed is placed on the swing block 50, the power source 21 is started, and the leveling unit 22 performs a vertical reciprocating hammering action. In this process, the displacement mechanism 40 controls the swing block 50 to slide along the first direction X in an arc shape. The displacement mechanism 40 is pushed by the user according to the position where the object to be processed needs to be hit, and the position of the swing block 50 is automatically adjusted according to the curved surface structure of the object to be processed, so that the hammering of the leveling unit 22 is always consistent with the surface curvature of the object to be processed, thereby realizing accurate arc surface hammering. The shaped arc surface 51 on the swing block 50 is consistent with the surface curvature of the object to be processed, so that the object can be stably supported during processing, and sliding or deviation during hammering is avoided.

[0026] If the object to be processed is a specific shoe model that needs to be shipped immediately, the surface of the swing block 50 can be pre-processed to match the surface curvature of the shoe model to be processed. In this way, when the shoe model is placed on the swing block 50, the curved surface of the swing block 50 can completely match the curvature of the shoe upper, achieving high-precision hammering processing. This method can be flexibly adjusted according to the shape of different shoe models, ensuring that each hammering process is targeted at a specific curvature, resulting in a smooth and high-quality finished surface, and improving processing efficiency.

[0027] In the above, the material of the swing block 50 is selected from shock-absorbing materials or hard materials, providing different hammering effects according to processing needs. Shock-absorbing materials reduce the rebound force to prevent damage, and hard materials increase the hammering force.

[0028] Please continue to refer to Figure 2 The leveling mechanism 20 further includes a stroke adjustment device 23 for controlling the hammering range of the leveling unit 22, thereby matching different hammering requirements of the object to be processed. The stroke adjustment device 23 can be manually or automatically set to adjust the up and down stroke of the leveling unit 22, so that the leveling unit 22 can be limited within the required stroke range when vertically reciprocating.

[0029] Please continue to refer to Figure 2 The pushing unit 42 is flat relative to the surface of the swing block 50, facilitating the installation of the swing block 50.

[0030] Please continue to refer to Figure 2 The surface of the swing block 50 is smooth, facilitating good adhesion to the object to be processed and providing uniform hammering support.

[0031] Please continue to refer to Figure 3 and Figure 4 in combination with Figure 2 The displacement mechanism 40 includes two pushing units 42 and a displacement unit 43. The opposite sides of the pushing unit 42 each have an arc-shaped sliding groove 421 of the same shape, and the displacement unit 43 slides in the arc-shaped sliding groove 421.

[0032] Please continue to refer to Figure 3 and Figure 4 in combination with Figure 2, the displacement unit 43 includes a positioning column 44 and a sliding block 45, the sliding block 45 is arranged at the top of the positioning column 44 to form a T-shaped structure, and the sliding block 45 slides between the two arc-shaped sliding grooves 421, and the positioning column 44 is fixedly arranged at the top of the rotating block 41. Based on the above structure, the sliding block 45 is limited by the positioning column 44 and cannot move independently, but slides in the arc-shaped sliding groove 421 along with the displacement of the pushing unit 42. When the user operates the pushing unit 42, the sliding block 45 generates a relative displacement sliding action in the arc-shaped sliding groove 421, so that the swing block 50 moves correspondingly in an arc shape, and the hammering position of the flattening unit 22 always corresponds to the arc-shaped surface of the swing block 50.

[0033] Please continue to refer to Figure 3 and Figure 4 and Figure 2 , after the pushing units 42 are attached to each other, the bottoms of the arc-shaped sliding grooves 421 jointly form a displacement channel 422, the width of the displacement channel 422 is greater than the diameter of the positioning column 44 along the second direction Y, and the width of the displacement channel 422 is less than the length of the sliding block 45. The displacement channel 422 limits the sliding range of the displacement unit 43 in the arc-shaped sliding groove 421, and the displacement channel 422 can limit the sliding block 45 to avoid the sliding block 45 from exceeding the hammering area of the flattening mechanism 20.

[0034] Please continue to refer to Figure 5 and Figure 6 and Figures 1 to 4 , the displacement mechanism 40 includes the rotating block 41, the rotating block 41 can rotate along the first direction X to provide more flexible angle adjustment capability to meet the needs of various arc-shaped surfaces. The rotation of the rotating block 41 enables the displacement mechanism 40 to adjust the angle for different shoe surface curves, to achieve uniform hammering effect and improve the flatness and appearance quality of the finished product.

[0035] Please refer to Figure 7 and Figures 1 to 6 , the flattening unit 22 of another embodiment of the present disclosure can be an ultrasonic heater, the ultrasonic heater can heat and vibrate the shoe surface arranged above the swing block 50, and it can be known from the figure that the bottoms of the two arc-shaped sliding grooves 421 jointly form a displacement channel 422, forming two displacement channels 422, the lengths of the two arc-shaped sliding grooves 421 are different, the width of the displacement channel 422 is greater than the diameter of the positioning column 44 along the second direction Y, and the width of the displacement channel 422 is less than the length of the plurality of sliding blocks 45. The two displacement channels 422 limit the sliding range of the displacement unit 43 in the arc-shaped sliding groove 421.

[0036] Based on the above structure, the present disclosure has the following advantages:

[0037] 1. Adapt to curved surface hammering needs: The arc-shaped sliding action of displacement mechanism 40 and the design of modeling arc surface 51 of swing block 50 enable the leveling unit 22 to accurately hammer or shake the curved surface of the object, solving the problem that traditional flat hammering machines cannot adapt to curved surfaces.

[0038] 2. Precise hammering control: The travel adjustment device 23 controls the leveling range of the leveling unit 22, and adjusts according to the thickness and shape requirements of different objects to ensure that the leveling travel meets the expectations and improves the processing precision.

[0039] 3. Reduce energy consumption and component wear: The travel adjustment device 23 precisely controls the travel of the leveling unit 22 within the hammering range, reducing invalid travel and leveling, reducing power consumption, and prolonging the service life of the leveling unit 22.

[0040] 4. Easy and stable operation: The design of displacement unit 43 simplifies the adjustment process of arc movement, and users only need to push displacement unit 43 in one direction to generate an arc-shaped sliding action.

[0041] The technical features of the above-described embodiments can be combined in any way. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described, but as long as the combinations of the technical features do not contradict, they should be considered within the scope of the present disclosure.
