Description

Technical Field

[0001] This utility model relates to a device for partial printing on shoe soles. Background Technology

[0002] When shoes are sold in the market, to differentiate between brands, logos are often placed on the upper, tongue, or sole to distinguish them from other brands. The soles are often printed using a printing machine. This machine is not only used to print anti-slip patterns but also to specifically print brand-specific logos. Currently, traditional printing equipment typically involves workers placing the shoes on a printing table, manually aligning them, and then printing on the sole. The lack of a fixed guide for the shoe during the printing process can lead to skewed patterns or incorrect printing placement, affecting the overall aesthetics of the shoe. Furthermore, during the pressing process, the printing plate often sticks to the sole after pressing, reducing printing efficiency and making it difficult to separate. Utility Model Content

[0003] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a partial printing device for shoe soles. By setting up printing components, the printing protrusions can be separated from the shoe sole more quickly, reducing adhesion between the shoe sole and the printing protrusions and avoiding poor printing quality. The printing protrusions can also be stored inside the pressure plate to prevent burns caused by accidental contact by printing workers.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a partial printing device for shoe soles, including a base, a printing component on the base, the printing component including a lower pressure plate, a pressure plate slidably connected to the lower pressure plate, a groove at the upper end of the pressure plate and a through hole at the bottom of the groove corresponding to the printing position, a heating plate in the groove and an elastic element at the bottom of the heating plate and the groove, a printing protrusion corresponding to the through hole on the heating plate and passing through the through hole, during printing, the printing protrusion protrudes from the lower end face of the pressure plate, and the protrusion length is the required printing thickness of the shoe sole.

[0005] Furthermore, the lower pressure plate has multiple circular holes distributed around its circumference, and each of these holes has an adjustment part for adjusting the protrusion length of the printing protrusion. Each adjustment part includes a circular rod at a position corresponding to a circular hole. The lower end of each circular rod passes through the circular hole and is connected to a lower circular plate, while the upper end of the circular rod is connected to an upper circular plate. A rotating rod is threaded into the upper circular plate, and the rotating rod is connected to a motor. The motor is fixed to the lower pressure plate, and the rotation of the motor causes the upper circular plate to move downwards along with the lower circular plate, thereby compressing the space of the heating plate in the groove.

[0006] Furthermore, the elastic element is a telescopic spring, and a heat insulation plate is provided at the upper end of the telescopic spring.

[0007] Furthermore, the base is provided with a hinge plate at the position corresponding to the printing component. The hinge plate is provided with a placement cavity for placing the shoe sole. The hinge plate is equipped with a flipping component, which is used to change the hinge plate from a horizontal state to an inclined state, thereby sliding the shoe sole out of the placement cavity.

[0008] Furthermore, the flipping component includes driven gears on both hinge ends of the hinge plate, the driven gears meshing with racks, the racks being laterally slidably connected to the base and equipped with telescopic cylinders, the telescopic movement of the racks being driven by the extension and retraction of the cylinders, thereby driving the hinge plate to flip.

[0009] Furthermore, the placement cavity is provided with an adjustment component for adjusting the position of the shoe sole. The adjustment component includes multiple sets of telescopic push rods, each with a guide plate at its end. Each guide plate is equipped with an independent distance sensor. When the distance detected by a certain distance sensor is inconsistent with the set distance, the corresponding telescopic push rod will activate the guide plate to push to reach the set distance.

[0010] Furthermore, the base is also provided with a pusher, which includes a collection box, in which shoe soles are stacked vertically. The collection box has a discharge port on the front side and a pusher port on the lower rear side. The pusher port is provided with a matching pusher plate, and the pusher plate is equipped with a cylinder.

[0011] Beneficial effects:

[0012] 1. The printing assembly of this application includes a lower pressure plate, a back pressure plate, a heating plate, printing protrusions on the heating plate, and an elastic element. During the printing process, the back pressure plate first presses against the sole of the shoe, which acts as a limit to prevent the sole from shifting position. Then, the lower pressure plate is driven by the driving element to continue moving downward. Due to the sliding connection between the back pressure plate and the lower pressure plate, the back pressure plate will not change position. The lower pressure plate will push the heating plate downward, and the printing protrusions will move downward simultaneously to print on the sole. After printing is completed, the lower pressure plate is driven upward by the driving element. In the early stage, the sole is still subjected to the downward force of the back pressure plate. The heating plate is accelerated upward by the reset of the elastic element, which accelerates the separation of the sole from the printing protrusions and reduces the adhesion between the sole and the printing protrusions. It continues to move upward until the lower pressure plate moves upward and resets with the back pressure plate, and the printing protrusions are received, avoiding burns to the printing workers when they come into contact with the printing protrusions during operation.

[0013] 2. Due to the different thicknesses of the soles, the depth of the printing during sole printing also varies. Therefore, this application also provides an adjustment part, which includes upper and lower circular plates, a circular rod, a rotating rod, and a motor. The motor drives the rotating rod to rotate, and the upper circular plate moves up and down along the length of the rotating rod. When the lower circular plate moves down, the heating plate moves down and the corresponding printing protrusion extends. The elastic element is compressed to a certain extent, providing the required printing thickness for the subsequent separation of the printing protrusion from the sole.

[0014] 3. This application uses an adjustment component to align the sole with the printing component. The adjustment component includes multiple sets of telescopic push rods and a distance sensor. The distance sensor detects the distance to determine the position of the sole and activates the telescopic push rods for fine adjustment, ensuring that the sole is directly below the printing component and avoiding errors in the printing position or the offset of the printing pattern.

[0022] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0023] For reference Figures 1-6 As shown, this utility model provides a partial printing device for shoe soles, including a base 1, a support 2 on the base 1, a platform 3 on the support 2, and a driving component 4 on the platform 3. The driving component 4 is hydraulically driven or screw driven (which is prior art and will not be described in detail here). The end of the driving component 4 passes through the platform 3 and is connected to a printing component 5. The printing component 5 includes a lower pressure plate 51, the inner wall of the lower pressure plate 51 is vertically slidably connected to the outer wall of the pressure plate 52, the outer wall of the lower pressure plate is provided with a vertical groove, and the lower pressure plate 51 is provided with a slider corresponding to the vertical groove. In order to facilitate the disassembly between the pressure plate 52 and the lower pressure plate 51, the lower pressure plate 51 is provided with an insertion port corresponding to the groove. The upper and lower ends of the insertion port are horizontally extended with horizontal plates, and the horizontal plates are provided with round holes. The slider is provided with a round hole corresponding to the round hole. The slider passes through the insertion port and is fixed in position by a nut after passing through the round hole through the screw. The upper end of the pressure plate 52 has a groove, and the bottom of the groove has a through hole corresponding to the printing position. A heating plate 53 is installed inside the groove. The side wall of the heating plate 53 has a heating interface, which can be detachably connected to a wire. The guide through platform 3 is connected to the power supply box and is also equipped with a switch. The heating plate 53 and the bottom of the groove have an elastic element 55, which is a telescopic spring. The upper end of the telescopic spring has a heat insulation plate to prevent the heat of the heat insulation plate from being transferred to the telescopic spring and thus affecting the elastic change of the telescopic spring. The heating plate 53 has a printing protrusion 54 corresponding to the through hole. The printing protrusion 54 passes through the through hole. During printing, the printing protrusion 54 is pressed down by the lower pressure plate 51 and passes through the through hole. The length of the protrusion is the thickness of the printing required for the sole. During the printing process, the pressure plate 52 first presses against the sole, acting as a limit to prevent the sole from shifting. Then, the lower pressure plate 51, driven by the drive component 4, continues to move downward. Due to the sliding connection between the pressure plate 52 and the lower pressure plate 51, the pressure plate 52 does not change position. The lower pressure plate 51 pushes the heating plate 53 downward, and the printing protrusion 54 moves downward simultaneously to print on the sole. After printing is completed, the lower pressure plate 51 is driven upward by the drive component 4. Initially, the sole is still subjected to the downward force of the pressure plate 52. The heating plate 53, reset by the elastic component 55, accelerates its upward movement, accelerating the separation of the sole from the printing protrusion 54 and reducing adhesion between the sole and the printing protrusion 54. The upward movement continues until the lower pressure plate 51 moves upward and resets with the pressure plate 52, and the printing protrusion 54 is received, preventing burns to the printing worker when in contact with the printing protrusion 54 during operation.

[0024] For reference Figure 3As shown, the depth of the print varies due to the different thicknesses of the soles. Therefore, this application also provides an adjustment part 6 on the lower pressure plate 51. The lower pressure plate 51 has multiple circular holes distributed around its circumference. The adjustment part 6 is located at the circular holes. Specifically, it includes a circular rod 61. The lower end of the circular rod 61 passes through the circular hole and is connected to a lower circular plate 62. The upper end of the circular rod is connected to an upper circular plate 63. A nut is provided in the middle of the upper circular plate 63. The nut is threadedly connected to a rotating rod 64. The rotating rod 64 is connected to a motor 65. The motor 65 is fixed on the lower pressure plate 51. The rotation of the motor 65 causes the upper circular plate 63 to move downward with the lower circular plate 62, thereby compressing the space of the heating plate 53 in the groove and determining the pressing depth of the print protrusion 54.

[0025] For reference Figure 5 As shown, a hinge plate 7 is provided on the base 1 corresponding to the position of the printing component 5. The hinge plate 7 is provided with a placement cavity 8 for placing the shoe sole. The hinge plate 7 is equipped with a flipping component 9. The flipping component 9 includes driven gears 91 on both hinge ends of the hinge plate 7. The driven gears 91 mesh with racks 92. The racks 92 are laterally slidably connected to the base 1 and are equipped with telescopic cylinders 93. The telescopic movement of the racks 92 is driven by the extension and retraction of the cylinders, thereby driving the hinge plate 7 to flip. After the printing is completed, the shoe sole moves away from the abutment plate platform 3 by tilting the hinge plate 7. It is also equipped with a pusher component 11, which includes a collection box 111. Shoe soles are stacked vertically inside the collection box 111. The collection box 111 has a discharge port on the front side and a push port on the lower rear side. The push port is equipped with a matching push plate 112. The push plate 112 is equipped with a cylinder. The cylinder pushes the push plate 112 to push the shoes at the bottom of the collection box 111 out of the discharge port and into the placement cavity 8. Through the combination of the pusher component 11 and the flipping component 9, the functions of automatic feeding and automatic unloading are realized.

[0026] Referring to the figure, in order to ensure that the sole can accurately match the printing component 5, an adjustment component 10 is provided in the placement cavity 8. The adjustment component 10 includes multiple sets of telescopic push rods 101. The ends of the telescopic push rods 101 are equipped with guide plates 102. Each guide plate 102 is equipped with an independent distance sensor 103. The sensor is equipped with a controller, which is used to open and close the telescopic push rods 101 (this is prior art and will not be described in detail here). Multiple sets of telescopic push rods 101 (such as...) Figure 5 (Distributed). When a distance sensor 103 detects a distance that is inconsistent with the setting, the corresponding telescopic push rod 101 will activate the guide plate 102 to push it to the set distance, thereby adjusting the position of the sole.

[0027] Working principle: The pusher 11 pushes the sole into the placement cavity 8. The adjustment 10 in the placement cavity 8 is activated to align the sole position. Since the position of the printing component 5 is fixed, the adjustment 10 adjusts the position of the sole according to the detection of the distance sensor 103. After alignment, the printing worker activates the printing component 5. The printing component 5 presses down to print on the sole. After printing is completed, the printing component 5 resets and the flipping component 9 is activated. After activation, the sole slides out of the placement cavity 8 along the inclined surface. This process is repeated to print on the sole until printing is completed.
