Description

TECHNICAL FIELD

[0001] The present application relates to the field of product lamination, and particularly relates to a leather lamination press. BACKGROUND

[0002] In today's product design and manufacturing, in order to improve the delicacy of product appearance and the use of hand feeling, the surface of many product shells will be attached with leather material. The lamination of leather and shell usually needs to uniformly apply glue on the back of the leather first, then cover the leather on the surface of the product shell, and complete the glue curing by applying pressure, keeping for a certain time and appropriate heating, which is called "pressure keeping". The process not only has high requirements for shape lamination, but also needs to avoid wrinkles or bubbles as much as possible during the application of pressure to ensure the lamination effect and appearance quality.

[0003] However, in order to provide reliable and stable pressure to the lamination part during the pressure keeping process, the traditional solution usually uses the way of upper and lower molds: under the cooperation of the upper and lower molds, the leather and the shell are clamped and fixed, so as to maintain the pressure and heat for a predetermined time. In addition to the problem of high cost of mold design and manufacturing in the early stage, the operator needs to align the product position first and then fix the upper and lower molds when using such molds, which has a long operation process and is difficult to improve the efficiency. In summary, the traditional pressure keeping device is difficult to meet the rapid and efficient production demand due to low efficiency and complex operation steps. CONTENT OF THE UTILITY MODEL

[0004] The present application aims to at least solve one of the technical problems existing in the prior art. To this end, the present application provides a leather lamination press which can simplify the steps of pressure keeping operation and improve work efficiency.

When the vertical floating block moves up and down, the horizontal movable block is extruded with the corresponding first inclined wedge surface, and the pressing block is moved close to or away from the corresponding retaining column under the cooperation of the corresponding elastic assembly.

[0006] The leather fitting presser machine according to the embodiment of the present application has at least the following beneficial effects.

At this time, the horizontal movable block drives the pressing block to move in the direction close to the retaining column under the cooperation of the elastic assembly, so that the pressing block is fitted with the product on the retaining column and maintained for a period of time, thereby completing the fitting and pressure maintaining operations. After a period of time, the vertical floating block is operated to move upward or downward, so that the pressing block is separated from the product on the retaining column, and then the product is taken out from the retaining column, thereby completing the whole pressure maintaining process. Through the upward and downward movement of the vertical floating block and the cooperation of the elastic assembly, the product can be clamped and released in a short time without manual locking. Compared with the traditional fixed upper and lower molds, the cumbersome disassembly and alignment steps are no longer needed, and only the product needs to be sleeved into the retaining column, thereby significantly simplifying the operation process and improving the work efficiency.

[0030] In the description of the present application, the description of the terms "one embodiment", "some embodiments", "exemplary embodiment", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in combination with the embodiment or example are included in at least one embodiment or example of the present application. In the present specification, the exemplary description of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0031] As Figures 1 to 4As shown, the leather fitting press mainly comprises a first bottom plate 100, a second bottom plate 200, a plurality of pressing assemblies, a driving assembly, and a plurality of retaining columns 500. The first bottom plate 100 is the base of the entire device, used for placing and fixing relevant power components or other accessory components; the second bottom plate 200 is installed on the first bottom plate 100 through a plurality of support columns 110, forming an upper and lower structure, and a limiting hole is formed at the center of the second bottom plate 200, which matches with the vertical floating block 410, so as to basically avoid the deflection of the vertical floating block 410 when moving up and down. On the upper surface of the second bottom plate 200, a plurality of pressing assemblies are installed. Each pressing assembly is composed of a horizontal movable block 310, a pressing block 320, and an elastic assembly 330, wherein the fixed end of the elastic assembly 330 is fastened on the second bottom plate 200, and the movable end of the elastic assembly 330 is connected with the horizontal movable block 310, so that when the horizontal movable block 310 is pushed or released by external force, the elastic assembly 330 can exert a certain elastic force on it. The pressing block 320 is fixed on one end of the horizontal movable block 310 away from the center of the second bottom plate 200, and the pressing block 320 is provided with a pressing recess, and the contour shape of the recess can be designed into a corresponding curved surface or polygonal surface according to the external structure of the product shell, so as to ensure that the fitting surface is consistent with the product outer surface as much as possible when pressing the product, thereby improving the fitting quality. It can be understood that for the bonding process with specific temperature requirements, a heating assembly can also be integrated at the pressing block 320 to assist in completing the heating fitting and pressure maintaining integrated process, so that the structure design of the pressing block 320 can reserve mounting holes or grooves for subsequent selection and matching of heating modules, temperature sensors and other components according to actual needs, to support the leather heating fitting process.

[0032] As shown in Figure 3 and Figure 4 The driving assembly comprises a vertical floating block 410. The vertical floating block 410 passes through the limiting hole at the center of the second bottom plate 200 and can float in the up-down direction. A plurality of first inclined wedge surfaces are arranged on the top outer edge surface of the floating block, corresponding to a plurality of horizontal movable blocks 310. In order to realize inclined wedge transmission, the inner side or the other end of the horizontal movable block 310 abuts against the corresponding first inclined wedge surface, and when the vertical floating block 410 moves upward or downward, the inclined wedge surface will slide relative to the horizontal movable block 310, thereby driving the horizontal movable block 310 to move towards or away from the center of the second bottom plate 200, so that the pressing block 320 approaches or moves away from the product surface under the cooperation of the elastic assembly 330.

[0033] Each dry retention column 500 corresponds to a compression assembly. One end of the retention column 500 is adapted to the shape of the product inner cylinder or cavity, so that the product can be fixed or centered by the retention column 500 during installation, avoiding misalignment during fitting; the other end is connected to the vertical floating block 410 through the strip-shaped connecting block 510, and when the vertical floating block 410 moves up and down with the driving assembly, the retention column 500 can also move up and down accordingly.

[0034] In use, the operator usually applies glue to the product shell or the back of the leather first, then fits the shell on the retention column 500, and performs simple alignment and positioning. Then, by operating the driving assembly (such as manual or other driving mechanism), the vertical floating block 410 is made to move downward or upward, at this time the horizontal movable block 310 drives the pressing block 320 to move towards the retention column 500 under the cooperation of the elastic assembly 330, so that the pressing block 320 is fitted with the product on the retention column 500 and maintained for a period of time, thereby completing the fitting and pressure maintaining operation. After a period of time, the vertical floating block 410 is operated to move upward or downward, so that the pressing block 320 is separated from the product on the retention column 500, and then the product is taken out from the retention column 500, completing the entire pressure maintaining process. Compared with the traditional fixed mechanical clamp which needs to rely on special molds, the present embodiment can complete batch fitting operation in a short time, and has obvious advantages in improving production efficiency and ensuring appearance quality.

[0035] As Figures 3 to 6In some more specific embodiments, one end of the strip-shaped connecting block 510 is connected with the area below the second bottom plate 200 of the vertical floating block 410, and the second bottom plate 200 is provided with a hole at the corresponding position of the retaining column 500, and the other end of the strip-shaped connecting block 510 is connected with the retaining column 500 through the hole. By arranging the strip-shaped connecting block 510 connecting the retaining column 500 and the vertical floating block 410 below the second bottom plate 200, the assembly is more convenient, and more installation space is reserved on the upper surface of the second bottom plate 200. Based on the above structural features, the horizontal movable block 310 and the retaining column 500 can be in the same vertical plane, and the strip-shaped hole 311 is arranged on the horizontal movable block 310 in the elastic force direction of the corresponding elastic assembly 330, which is used to allow the retaining column 500 to pass through, and the pressing recess of the pressing block 320 is directed to the center of the second bottom plate 200. For the above structure, when the elastic assembly 330 is in the default state, the thrust of the elastic assembly 330 will pull the horizontal movable block 310 to the center of the second bottom plate 200, so that the pressing block 320 applies radial or cladding pressure to the retaining column 500, thereby achieving the fitting and fixing of the product. At this time, the pressing recess precisely fits the outer surface of the product to obtain better pressure retention effect. When the vertical floating block 410 moves upward, the first inclined wedge surface at the top of the vertical floating block 410 will produce relative displacement with the other end of the horizontal movable block 310, thereby overcoming the thrust of the elastic assembly 330 and pushing the horizontal movable block 310 away from the center of the second bottom plate 200. Through this action, a gap is generated between the pressing block 320 and the retaining column 500, which is convenient for the operator to take out the product. In the above structure design, when the vertical floating block 410 moves downward, the elastic assembly 330 pushes the horizontal movable block 310 to move to the center of the second bottom plate 200, thereby driving the pressing block 320 to press the product; when the vertical floating block 410 moves upward, the first inclined wedge surface extrudes the horizontal movable block 310, so that the pressing block 320 is separated from the product. As can be seen, the cladding force of the pressing block 320 to the product is provided by the spring 334 of the elastic assembly 330, which is more controllable than the extrusion and sliding between the first inclined wedge surface and the horizontal movable block 310 to provide pressure. At the same time, the vertical floating block 410 is in the release state when it rises, because the retaining column 500 rises or falls synchronously with the vertical floating block 410, so when the pressing block 320 is in the release state, the retaining column 500 is also in the rising state, which is more conducive to taking out the product after pressure retention and sleeving a new product for the retaining column 500.

[0036] In some embodiments, the elastic assembly 330 mainly consists of a concave fixed block 331, a movable block 332, a guide column 333 and a spring 334. As shown in FIG. 6, the movable block 332 is arranged in the concave fixed block 331, and the guide column 333 is arranged in the movable block 332. The spring 334 is arranged in the guide column 333. The movable block 332 is connected with the strip-shaped hole 311 of the horizontal movable block 310, and the guide column 333 is connected with the strip-shaped connecting block 510 of the vertical floating block 410. Figure 3 and Figure 7As shown, the concave fixing block 331 is installed on the upper surface of the second bottom plate 200 to provide a mounting base for the spring 334 pre-tightening and the movable block 332 guiding. The shape of the concave fixing block 331 can be integral or partially opened to accommodate the installation space of the movable block 332 and the guide column 333. The movable block 332 is slidably arranged on the guide column 333, and a corresponding through hole or guide sleeve is usually processed at the corresponding position to ensure that the movable block 332 can only make linear reciprocating motion on the guide column 333, avoiding lateral shaking. The spring 334 is arranged around the outer periphery of the guide column 333, one end of which abuts against the protrusion of the concave fixing block 331, and the other end abuts against the movable block 332.

[0037] As can be understood, the first inclined wedge surface corresponding to the top of the vertical floating block 410 and the horizontal movable block 310 is provided with a second inclined wedge surface facing the first inclined wedge surface. Specifically, the second inclined wedge surface matches the first inclined wedge surface in terms of included angle, surface roughness, etc. Through the cooperation between the two opposite inclined surfaces, when the vertical floating block 410 moves up and down, the sliding along the inclined surface can efficiently convert the vertical force into horizontal thrust, thereby driving the horizontal movable block 310 to move accurately away from the center. By using this double inclined surface cooperation mode, the force transmission efficiency can be further improved and the wear at the inclined surface contact can be reduced. Further, a lubricant can be installed between the two inclined surfaces or a wear-resistant material can be used, and the friction between the inclined surfaces can be effectively controlled, so that better stability and service life can be maintained in high-speed reciprocating or long-term running environment.

[0038] As can be understood, in addition to the vertical floating block 410, the driving assembly can also include a driving member 420 installed on the first bottom plate 100 and a driving screw 430 connected thereto. Figure 5 As shown, the center of the vertical floating block 410 is processed with a threaded hole matched with the driving screw 430, one end of the driving screw 430 is connected with the output shaft of the driving member 420, and the other end is arranged in the threaded hole of the vertical floating block 410. Through this threaded engagement mode, when the driving member 420 is started and drives the driving screw 430 to rotate, the vertical floating block 410 can be accurately moved in the up-down direction under the guidance of the limiting hole. In order to further avoid the rotation of the vertical floating block 410 and ensure the stability of the movement path, the limiting hole is designed as a non-circular shape, such as a square or an ellipse, and the external shape of the vertical floating block 410 corresponds to the non-circular hole.

[0039] In some embodiments, the retaining column 500 is provided with 4, for example, Figure 2As shown, the included angle between the adjacent retaining columns 500 is 90. Correspondingly, the device is also provided with four pressing assemblies, so that the device can simultaneously press four products. At the same time, because the retaining columns 500 are arranged at equal intervals around the center of the second bottom plate 200, the stress of the vertical floating block 410 is more uniform during the operation of the equipment, which can improve the service life of the equipment.

[0040] Optionally, in order to meet the needs of heat insulation, anti-scalding and auxiliary pressing, etc., an end of the horizontal movable block 310 away from the center of the second bottom plate 200 is provided with a tile-shaped plate 340 in addition to the pressing block 320, as shown in Figure 1 and Figure 2 The tile-shaped plate 340 is usually made of a material with low thermal conductivity, such as ceramic, high-temperature-resistant plastic or composite material, which can not only effectively block heat leakage when the heating module is working to prevent accidental scalding when touching, but also can assist in pressing the local area by pressing the tile-shaped plate 340 when the pressing block 320 cannot completely cover the surface of the product. During the downward movement of the vertical floating block 410, the plurality of tile-shaped plates 340 gradually approach the center of the second bottom plate 200 together with the horizontal movable block 310, and finally form a cylindrical structure, which can assist in heat preservation and avoid external environmental interference. Further, the top end of the supporting column 110 can also be provided with an upper cover plate 210. As shown in Figure 1 and Figure 2 The upper cover plate 210 can effectively block dust, debris or other foreign matter from falling into the mechanical interior, preventing the foreign matter from falling into the device to cause jamming or increase the friction. At the same time, the upper cover plate 210 can also act as a protective cover to a certain extent, reducing the risk of touching the internal heating components or moving parts during operation.

[0041] The embodiments of the present application are described in detail above in combination with the drawings, but the present application is not limited to the above embodiments, and various changes can be made within the knowledge range of ordinary skilled in the art without departing from the purpose of the present application. In addition, the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
