Description

Technical Field

[0001] This utility model relates to the technical field of footwear processing equipment, specifically a shoe upper pressing and heating machine. Background Technology

[0002] A shoe upper heat press is a device used in footwear manufacturing to bond or shape shoe upper materials through a hot pressing process.

[0003] A search revealed a Chinese utility model patent with publication number "CN222737380U" that discloses "a shoe upper heat press machine". The machine works by placing the shoe upper on a placement plate on the outside. After placement, a motor drives a threaded rod to rotate, thereby moving the placement plate into a heat press frame. After heat pressing is completed, the motor reverses, thereby moving the placement plate out of the heat press frame, thus recycling the heat-pressed shoe upper. This eliminates the need for workers to manually place the shoe upper on the heat press, effectively preventing workers from being burned.

[0004] However, in actual use, the aforementioned disclosed device and similar existing devices cannot adapt to different shoe curvatures due to the fixed design of the hot pressing frame, resulting in uneven stress on the shoe surface after hot pressing, which easily leads to wrinkles or deformation. Utility Model Content

[0005] The purpose of this invention is to provide a shoe upper pressing and heating machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A shoe upper pressing heat press, comprising:

[0008] The assembly column is fitted with an upper pressure component and a lower pressure component at each end;

[0009] The pressing component includes:

[0010] The force-bearing platform is fixedly connected to the bottom of the assembly column at its outer end, and its interior is used to accommodate the power supply.

[0011] The load-bearing panel is fixedly installed on the top surface of the load-bearing platform;

[0012] Two movable notches are symmetrically opened on both sides of the surface of the supporting panel;

[0013] A two-way telescopic rod is installed at the center of the bottom surface of the load-bearing panel;

[0014] The lower heating plate is electrically connected to the power supply; the two sides of the bottom are respectively hinged to the two telescopic ends of the bidirectional telescopic rod through movable protrusions with through-holes.

[0015] When the upper pressing component moves to the lower pressing component and performs the stamping action, the lower pressing heating plate changes from the initial convex shape to a flat shape under pressure. After the stamping process is completed, the lower pressing heating plate returns to the convex state based on its elastic reset characteristic.

[0016] Furthermore, the pressing heating plate is set to have a raised height based on the minimum extension position of the bidirectional telescopic rod, and the raised height corresponds to the heat-pressing and shaping curvature required for the shoe upper;

[0017] The maximum and minimum extension positions of the bidirectional telescopic rod are defined as follows: the maximum extension position corresponds to the limit position when the pressing heating plate reaches a completely flat state, and the minimum extension position corresponds to the reference position when the pressing heating plate returns to its initial convex state. This is used to ensure the control and repeatability of the hot-pressing shaping arc.

[0018] Furthermore, a power supply harness is installed between the pressure heating plate and the power supply, and a closing switch is installed at the assembly point of the power supply harness and the pressure heating plate. The closing switch is used to manually cut off the power supply to the pressure heating plate and the power supply.

[0019] Furthermore, the upper pressure assembly includes: a movable sleeve, which is fitted and fixed to the top of the assembly column;

[0020] The pressure frame is mounted on the surface of the movable sleeve at one end and can move vertically along the surface of the movable sleeve by means of manual force.

[0021] The top surface of the upper pressure plate is fixed to the bottom of the pressure frame.

[0022] Furthermore, a control terminal is fixed to the surface of the movable sleeve away from the pressure frame, and the control terminal is electrically connected to the power supply.

[0023] Furthermore, the top of the upper pressure plate is symmetrically fixed with handles, which are used to assist the operator in applying stable vertical pressure by pressing down on the heating plate.

[0024] Compared with the prior art, the beneficial effects of this utility model are:

[0025] This shoe upper heat press, through the design of a bidirectional telescopic rod and an elastic reset design of the lower heating plate, allows the lower heating plate to automatically change from a raised shape to a flat shape during the stamping process, and quickly return to its original shape after the pressure is released. This not only simplifies the operation steps, but also ensures the repeatability and consistency of the hot pressing and shaping curvature, reducing the need for manual adjustment.

[0026] In addition, the design of the manual closing switch enhances equipment safety and facilitates power cut-off in emergencies; while the combination of the handle and control terminal allows operators to apply stable vertical pressure and precisely adjust temperature parameters, further improving the accuracy and reliability of thermoforming.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Before understanding the technical solution proposed in this application, it is important to understand that the actual application scenario for the shoe upper heat press proposed in this solution is the heat pressing and shaping process of shoe uppers (especially the toe and waist parts of sports shoes and casual shoes) in small and medium-sized shoe factories or workshops. Specifically, such as Figures 1-4 As shown, this solution relates to a shoe upper pressing and heating machine, comprising:

[0034] The assembly column 1 serves as the overall support frame, with the upper pressure component 2 and the lower pressure component 3 fixedly assembled at the top and bottom respectively to ensure structural stability.

[0035] It should be noted that in this application, the pressing component 3 includes a force-bearing platform 301, the outer end of which is welded and fixed to the bottom end of the assembly column 1. The interior is designed as a hollow cavity for safely accommodating and connecting the assembly power supply. The bearing panel 302, made of rigid material, is bolted to the top surface of the force-bearing platform 301 and is used to support workpieces such as shoe uppers. Two movable notches 307 are symmetrically opened on the left and right sides of the surface of the bearing panel 302, allowing the movable protrusions 304 to move freely through them. A bidirectional telescopic rod 306 is vertically installed at the center of the bottom surface of the bearing panel 302. The pressing heating plate 305 is electrically connected to the power supply and integrates a heating element. Its bottom sides are hinged to the two telescopic ends of the bidirectional telescopic rod 306 via the movable protrusions 304 penetrating the movable notches 307, ensuring lifting and lowering.

[0036] It should be added that when the upper pressing component 2 moves to the lower pressing component 3 and performs the stamping action, the lower pressing heating plate 305 gradually compresses from the initial convex shape to the flat shape under the action of external vertical pressure, realizing hot pressing and shaping; after the stamping process is completed, the lower pressing heating plate 305 automatically returns to the convex state based on the reset characteristics of the built-in spring or elastic material, ready for the next operation.

[0037] As a preferred embodiment, in this embodiment, the pressing heating plate 305 is precisely set with a protrusion height based on the minimum extension position of the bidirectional telescopic rod 306. This protrusion height is pre-calibrated to match the heat-pressing and shaping curvature required for the shoe upper, ensuring the molding effect.

[0038] Furthermore, in this embodiment, the maximum and minimum extension positions of the bidirectional telescopic rod 306 are mechanically limited. The maximum extension position corresponds to the limit position when the pressing heating plate 305 reaches a completely flat state, and the minimum extension position corresponds to the reference position when the pressing heating plate 305 returns to the initial convex state. This design is used to ensure the precise control and repeatability of the hot pressing shaping arc and avoid deviation.

[0039] As a preferred embodiment, in this embodiment, a flexible power supply harness 303 is assembled between the pressure heating plate 305 and the power supply. A manual closing switch is installed at the assembly point of the power supply harness 303 and the pressure heating plate 305. The closing switch is used to manually cut off the power supply to the pressure heating plate 305 and the power supply in maintenance or emergency situations, thereby improving safety.

[0040] As a preferred embodiment, in this embodiment, the upper pressure assembly 2 includes: a movable sleeve 201, which is sleeved and fixed to the top of the assembly column 1 using a sleeve structure, allowing axial sliding; a pressure frame 203, one end of which is mounted on the surface of the movable sleeve 201 via a slide rail, and can move vertically axially on the surface of the movable sleeve 201 by means of manual force applied by the operator, thereby transmitting pressure; and an upper pressure plate 205, which is made of heat-resistant material, and its top surface is fixed to the bottom of the pressure frame 203 by screws, for direct contact with the workpiece.

[0041] It should also be noted that, in this embodiment, a control terminal 202 is fixed on the surface of the movable sleeve 201 away from the pressure frame 203. The control terminal 202 integrates a display screen and buttons and is electrically connected to the power supply. It is used to set and monitor heating temperature and pressure parameters. In addition, handles 204 are symmetrically fixed on the top of the upper pressure plate 205. The handles 204 have an anti-slip design and are used to assist the operator in applying stable and uniform vertical pressure to the heating plate 305 to ensure operating accuracy.

[0042] Finally, it should be noted that during operation of the device proposed in this application, the operator first places the shoe upper to be processed flat on the bearing panel 302, ensuring that the area to be shaped is aligned with the protrusion of the lower heating plate 305. Then, the operator holds the handle 204 at the top of the upper pressure plate 205 with both hands and applies vertical pressure downward, causing the upper pressure assembly 2 to move downward along the assembly column 1. The upper pressure plate 205 first contacts and presses against the shoe upper. As the pressure continues to increase, the lower heating plate 305 receives pressure transmitted from the shoe upper, and the movable protrusions 304 on both sides of its bottom slide within the movable notch 307, forcing the bidirectional telescopic rod 306 to extend from its minimum extension position (corresponding to the initial protrusion state). The protrusion height of the lower heating plate 305 gradually decreases, and finally transforms into a complete extension when the bidirectional telescopic rod 306 reaches its maximum extension position. In the fully flat state, the shoe upper is tightly clamped between the upper pressure plate 205 and the lower pressure heating plate 305. During this process, the lower pressure heating plate 305 is powered by the power supply through the power supply harness 303 to heat and soften the shoe upper evenly. Combined with pressure, it plastically deforms and conforms to the preset curvature. After the stamping process is completed, the operator releases the handle 204 to remove the pressure. Under the action of the elastic element (spring) built into the bidirectional telescopic rod 306, the lower pressure heating plate 305 automatically retracts and returns to the initial convex state corresponding to its minimum extension position through the guide of the movable protrusion 304, preparing for the next operation. In addition, the operator can set the heating temperature and time parameters through the control terminal 202. During non-operation periods or in emergency situations, the power supply to the lower pressure heating plate 305 can be manually cut off by closing the switch to ensure safety.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended embodiments and their equivalents.
