Description

TECHNICAL FIELD

[0001] The present disclosure relates to a planer, in particular, an automatic planer capable of planing a three-dimensional vamp. BACKGROUND

[0002] A shoe upper is usually sewn from multiple pieces of material, especially in complex shoe models, multi-level and multi-curved splicing technology is used. However, due to the thickness difference of leather or other materials, the sewing 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 mechanism of the commonly used hammering machine will cause poor hammering effect, 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 an automatic 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 an automatic planer, which comprises a machine table, a planing mechanism, a cantilever, a displacement mechanism and a swing block. The planing mechanism is arranged above the machine table, and the planing mechanism comprises a power supply device and an ultrasonic heater driven by the power supply device; one end of the cantilever is arranged on the machine table, and the other end of the cantilever extends downward relative to the planing mechanism; the displacement mechanism is arranged at the end of the cantilever away from the machine table and below the planing mechanism, and the displacement mechanism can produce an arc sliding motion in a first direction; the swing block is arranged on the top of the displacement mechanism and below the planing mechanism, and the top of the swing block has a shaped curved surface corresponding to the arc sliding motion, and the ultrasonic heater is displaced up and down along the surface of the shaped curved surface.

[0006] In another embodiment of this disclosure, the displacement mechanism includes two pushing units and a displacement unit. The opposing sides of the pushing units each have two arc-shaped grooves of the same shape, and the displacement unit slides in the arc-shaped grooves.

[0007] In another embodiment of this disclosure, the displacement unit consists of a positioning post and two sliders. The sliders are positioned parallel to the positioning post at the positions corresponding to the arc-shaped grooves, and the sliders can slide between the two arc-shaped grooves.

[0008] In another embodiment of this disclosure, the machine tool further includes a clamping mechanism having a clamping space, the clamping mechanism being disposed at the end of the cantilever away from the machine tool, and the pushing unit being located in the clamping space.

[0009] In another embodiment of this disclosure, the clamping mechanism includes a stabilizing part and two clamping parts, the clamping parts being located on both sides of the stabilizing part, and the clamping parts and the stabilizing part together forming a clamping space.

[0010] In another embodiment of this disclosure, the bottom edge of the stabilizing portion extends into a supporting flange, which is located between the two clamping portions and abuts against the bottom surface of the pushing unit.

[0011] In another embodiment of this disclosure, the machine tool further includes a preload adjustment mechanism, which is combined with an ultrasonic heater. The preload adjustment mechanism includes a pressure plate, an elastic member, and a locking member. The pressure plate presses against the elastic member and the locking member limits the pressing distance of the pressure plate.

[0012] In another embodiment of this disclosure, the machine tool further includes a vertical displacement mechanism, which is combined with a preload adjustment mechanism and is driven by a power transmission device to move back in a second direction, which is perpendicular to the first direction.

[0013] In another embodiment of this disclosure, the machine tool further includes a feeding mechanism, which is combined with a displacement mechanism and drives the displacement mechanism to move back along a first direction.

[0014] In another embodiment of this disclosure, the ultrasonic heater further includes a controller for controlling the output power of the ultrasonic heater.

[0015] Based on the above, the advantage of this disclosure lies in that, through the arc-shaped sliding action of the displacement mechanism combined with the curved surface of the swing block, the leveling mechanism can precisely level the three-dimensional curved surface of an object. This not only improves the problem of uneven hammering of commonly used curved surfaces but also enhances the stability of the leveling process and the appearance quality of the finished product. Furthermore, it maintains a relatively low noise level during processing, making it suitable for applications such as shoe uppers that require three-dimensional leveling, thereby improving product quality and aesthetics.

[0022] In order to more clearly illustrate the core ideas of the above-mentioned content, specific embodiments are provided below. 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 depicted using imaginary lines and the like in some drawings.

[0023] Referring to Figures 1 to 6 , the present disclosure provides an automated leveling machine 100, which includes a machine table 10, a leveling mechanism 20, a cantilever 30, a displacement mechanism 40, and a swing block 50. Through the automated leveling machine 100 of the present disclosure, the leveling processing of a three-dimensional curved surface object such as a shoe upper can be realized. As can be seen from the drawings, a first direction X, a second direction Y, and a third direction Z together define a three-dimensional space.

[0024] The leveling mechanism 20 is arranged above the machine table 10, and the leveling mechanism 20 includes a power supply device 21 and an ultrasonic heater 22, the ultrasonic heater 22 being driven by the power supply device 21; one end of the cantilever 30 is arranged on 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 an end of the cantilever 30 away from the machine table 10 and below the leveling mechanism 20, and the displacement mechanism 40 can generate an arc sliding action along the first direction X; the swing block 50 is arranged on top of the displacement mechanism 40 and below the leveling mechanism 20, and the swing block 50 has a modeling curved surface 51 on top corresponding to the arc sliding action, and the ultrasonic heater 22 is displaced up and down along the surface of the modeling curved surface 51.

[0025] Referring to Figure 3 and Figure 4 in combination with Figure 1 and Figure 2The automatic leveling machine 100 of the present disclosure can provide stable and precise leveling processing. When the ultrasonic heater 22 is started, high-frequency vibration and heat energy are generated, causing the upper or other three-dimensional curved surface object placed on the swing block 50 to soften. Then, the displacement mechanism 40 drives the swing block 50 to perform an arc sliding action in the first direction X, so that the upper contacts the ultrasonic heater 22 under uniform pressure and temperature conditions to achieve the desired leveling effect.

[0026] Please continue to refer to Figure 5 and Figure 6 and combine with Figure 1 and Figure 2 , the machine 10 further includes a clamping mechanism 60, the clamping mechanism 60 has a clamping space 63, the clamping mechanism 60 is arranged at the end of the cantilever 30 away from the combined machine 10, and the two pushing units 41 are located in the clamping space 63; the clamping mechanism 60 includes a stable part 61 and two clamping parts 62, each clamping part 62 is located on both sides of the stable part 61, and the clamping part 62 and the stable part 61 together constitute the clamping space 63. In this way, the clamping mechanism 60 can effectively stabilize the shoe body and improve the leveling precision, ensuring that the shoe body does not displace or deform during the leveling process due to mechanical movement or heat energy. When the swing block 50 performs an arc sliding action, the clamping mechanism 60 stably clamps the shoe body, making it tightly fit the modeling curved surface 51 of the swing block 50, ensuring that the heat energy and pressure applied by the ultrasonic heater 22 can uniformly act on the surface of the shoe body. In addition, the clamping mechanism 60 can adapt to different sizes and shapes of shoe bodies, and can automatically adjust the distance or clamping force of the clamping part 62 according to different processing needs, so that it can be used for leveling various uppers and three-dimensional curved surface objects.

[0027] Please continue to refer to Figure 1 and Figure 2 The bottom edge of the stable part 61 extends a supporting edge 611, the supporting edge 611 is located between the clamping parts 62, and the supporting edge 611 abuts the bottom surface of the two pushing units 41. In this way, the supporting edge 611 provides additional support effect, which can effectively reduce the shaking or displacement of the displacement mechanism 40 caused by vibration or mechanical stress, ensuring that the displacement mechanism 40 can maintain stability during operation.

[0028] Please continue to refer to Figure 1 and Figure 2The displacement mechanism 40 includes two pushing units 41 and a displacement unit 42. The opposite sides of the pushing units 41 are respectively provided with two arc-shaped sliding grooves 411 of the same shape, and the displacement unit 42 slides in the arc-shaped sliding grooves 411. The displacement unit 42 includes a positioning column 421 and two sliding blocks 422. The sliding blocks 422 are arranged in parallel with the positioning column 421 at positions corresponding to the arc-shaped sliding grooves 411, and the sliding blocks 422 can slide between the arc-shaped sliding grooves 411. In this way, the displacement unit 42 can smoothly slide in the arc-shaped sliding grooves 411 of the pushing units 41, so that the positioning column 421 and the sliding blocks 422 together ensure that the displacement mechanism 40 can accurately move along a predetermined arc-shaped track. The above structure not only improves the running stability of the displacement mechanism 40, but also ensures that the swing block 50 maintains a consistent movement track during the flattening process, thereby improving the flattening precision of the shoe body or the three-dimensional curved surface object and reducing uneven processing problems caused by sliding errors.

[0029] Please continue to refer to Figure 1 and Figure 2 The machine 10 further includes a pre-tightening adjustment mechanism 70 combined with the ultrasonic heater 22. The pre-tightening adjustment mechanism 70 includes a pressing plate 71, an elastic member 72, and a locking member 73. The pressing plate 71 presses against the elastic member 72, and the locking member 73 limits the pressing distance of the pressing plate 71. In this way, the pre-tightening adjustment mechanism 70 can provide appropriate elastic pre-tightening through the elastic member 72, so that the ultrasonic heater 22 can stably contact the shoe body or the three-dimensional curved surface object during the flattening process, and ensure uniform pressure distribution. The pressing plate 71 presses against the elastic member 72, and the locking member 73 limits the pressing distance of the pressing plate 71, which can effectively adjust the contact pressure of the ultrasonic heater 22, avoid excessive extrusion that damages the object, or insufficient pressure that affects the flattening effect, and further improve the stability and precision of the flattening process.

[0030] Please continue to refer to Figure 1 and Figure 2 The machine 10 further includes a vertical displacement mechanism 80, which can be a sliding block matched with a sliding rail. The vertical displacement mechanism 80 is combined with the pre-tightening adjustment mechanism 70, and is driven by a power transmission device 81 to reciprocatingly displace in a second direction Y, and can indirectly drive the ultrasonic heater 22 to vertically displace. The second direction Y is perpendicular to the first direction X.

[0031] Please continue to refer to Figure 1 and Figure 2, the machine table 10 further comprises a feeding mechanism 90, which is combined with the displacement mechanism 40 and drives the displacement mechanism 40 to reciprocate along the first direction X. The feeding mechanism 90 can be divided into two categories: one is driven by a pneumatic cylinder or a hydraulic cylinder, only with an ON / OFF control mode, that is, only a fixed stroke linear motion; the other is a linear motor or a servo motor matched with a screw rod and a sensor (such as an electronic ruler or an encoder), which can accurately control the speed and movement distance, and is suitable for application scenarios that require high-precision feeding.

[0032] Please continue to refer to Figure 1 and Figure 2 The ultrasonic heater 22 further comprises a controller 23 for controlling the output power of the ultrasonic heater 22, so as to adjust the appropriate ultrasonic energy and heating intensity according to the material and thickness of different shoe bodies or three-dimensional curved surface objects.

[0033] Based on the above structure, the present disclosure has the following advantages:

[0034] 1. High-precision flattening effect: The ultrasonic heater 22 provides high-frequency vibration and heat energy to uniformly soften the vamp or three-dimensional curved surface object, effectively improving the flattening quality, and the processing sound of the ultrasonic heater 22 is significantly smaller than that of the commonly used hammering processing; in addition, the arc-shaped sliding action of the displacement mechanism 40 ensures that the processed object and the ultrasonic heater 22 can be stably contacted, avoiding uneven flattening.

[0035] 2. Improved clamping stability: The clamping mechanism 60 can stably clamp the shoe body, ensuring that there is no displacement or deformation during the flattening process, improving the processing precision, and the supporting edge 611 provides additional support to reduce the shaking of the displacement mechanism 40 caused by vibration or external force, ensuring stable operation.

[0036] 3. Maintain the processing quality: The pre-tightening mechanism 70 provides appropriate pressure through the elastic member 72 to ensure that the ultrasonic heater 22 and the shoe body are in uniform contact, avoiding the influence of excessive or insufficient pressure on the processing effect.

[0037] The technical features of the above-described embodiments can be combined in any manner. 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 exist, they should be considered as the scope of the present disclosure.
