Description

Technical Field

[0001] This utility model relates to the field of soap production technology, and in particular to a soap pressing machine that prevents hand pinching. Background Technology

[0002] After a series of processing steps, the saponified material becomes soap blanks. Before packaging, these soap blanks need to be stamped and molded. For example, company logos, cartoon designs, trademark names, and other information may be printed on them. Current technology uses a cylinder to directly press a positive or negative mold onto the soap blank, creating the imprint. The soap blank is then manually placed under the mold and manually removed after stamping. This process, with hands too close to the stamping mechanism, easily leads to safety accidents.

[0003] A soap stamping machine with anti-pinch function is disclosed in publication number CN214295314U. It includes a base plate and a bracket mounted on the base plate. A stamping cylinder is mounted on the bracket, and a mold is mounted on the output end of the stamping cylinder. A stamping platform is provided on the base plate at a corresponding position below the mold. A loading platform extending outward is provided on the side of the base plate away from the bracket. A baffle extending in the same direction as the loading platform is provided on the edge of the stamping platform. A first cylinder is provided on the side of the baffle away from the stamping platform. A push plate is provided at the output end of the first cylinder that crosses the baffle and extends to the side of the stamping platform near the bracket. A feeding mechanism for feeding soap blanks onto the stamping platform is provided on the side of the stamping platform away from the base plate.

[0004] The aforementioned patent enables automated loading and unloading of soap, eliminating the need for manual intervention and preventing human harm. However, although the patent utilizes baffles to block the pushed soap and ensure it is positioned on the stamping platform, the lack of a positioning structure on the outside of the soap during the stamping process makes it prone to displacement or rotation, resulting in inaccurate stamping patterns and affecting the quality of the finished product. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a soap stamping machine that prevents hand pinching. It aims to improve the problem that the lack of a positioning structure on the outside of the soap during the stamping process causes the soap to easily shift or rotate, resulting in inaccurate stamping pattern positions and affecting the quality of the finished product.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] The device includes a hollow base, with mounting frames fixed at the four corners of the upper end of the hollow base. A load-bearing crossbeam is fixed at the upper end between every two mounting frames, and a top plate is fixed between the two load-bearing crossbeams. A conveyor belt is mounted on the upper end of the hollow base and between the two load-bearing crossbeams. A telescopic cylinder is installed at the center of the top plate, and a stamping die is fixed at the telescopic end of the telescopic cylinder. The stamping die is located at the upper end of the conveyor belt. Guide grooves are opened inside both ends of the hollow base, and push plates are slidably connected to the inner sides of the two guide grooves. A positioning component is set between the two push plates and at the upper end of the conveyor belt.

[0008] Preferably, the positioning component includes a gap-filling base. Two gap-filling bases are arranged between the two push plates and at the upper end of the conveyor belt. The two gap-filling bases are symmetrically arranged. A baffle plate is fixed to the upper end of each gap-filling base. An electric telescopic rod is installed inside each baffle plate. An arc-shaped pressure plate is fixed to the telescopic end of the electric telescopic rod. The two arc-shaped pressure plates are symmetrically arranged.

[0009] Preferably, the upper ends of the two push plates, which are close to each other, are symmetrically fixed with connecting rods, and each pair of connecting rods is fixed to the gap-filling base.

[0010] Preferably, a spacer is fixed at the center of the inner side of the hollow base, and a dual-axis motor is installed at the center of the spacer. Both output ends of the dual-axis motor are fixed with screws. The two push plates are located outside the two screws and are threadedly connected to the screws. The two screws are symmetrically arranged.

[0011] Preferably, each of the guide grooves is symmetrically provided with guide posts on its inner side, the guide posts are fixed to the hollow base, and the push plate is slidably connected to the guide posts.

[0012] Preferably, four photoelectric sensors are respectively installed between the four mounting frames, and the four photoelectric sensors are respectively installed and fixed to the four mounting frames.

[0013] Preferably, rubber feet are fixed at the four corners of the bottom of the hollow base.

[0014] This utility model has the following beneficial effects:

[0015] In this invention, four photoelectric sensors, each positioned between four mounting frames, enable precise positioning and detection of the soap blanks conveyed on the conveyor belt. This allows the soap blanks to align with the stamping die. A positioning component, located between two push plates at the top of the conveyor belt and connected to the two push plates by two screws, positions and clamps the soap blanks, ensuring precise alignment between the soap blanks and the stamping die. This effectively prevents displacement or rotation of the soap blanks during the stamping process when the telescopic cylinder moves the stamping die downwards, significantly improving the positional accuracy of the stamped pattern and product consistency. Simultaneously, it retains the original anti-pinch safety design, making it suitable for high-precision stamping operations in soap production. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Reference Figure 1-4An embodiment of this utility model includes a hollow base 1, with four support frames 2 fixed at the four corners of the upper end of the hollow base 1. A load-bearing crossbeam 3 is fixed at the upper end between every two support frames 2, and a top plate 4 is fixed between the two load-bearing crossbeams 3. A telescopic cylinder 6 is installed at the center inside the top plate 4, and a stamping die 7 is fixed at the telescopic end of the telescopic cylinder 6. In order to automatically feed material to the lower end of the stamping die 7, a conveyor belt 5 is installed at the upper end of the hollow base 1 and between the two load-bearing crossbeams 3. The stamping die 7 is located at the upper end of the conveyor belt 5. The conveyor belt 5 facilitates automatic feeding to the lower end of the stamping die 7, and can also drive it to automatically unload after the soap blank is stamped, so as to eliminate the need for manual intervention and avoid the occurrence of hand pinching.

[0024] Before the stamping begins, in order to detect the position of the soap blank conveyed on the conveyor belt 5, four photoelectric sensors 8 are respectively installed between the four mounting frames 2. The four photoelectric sensors 8 are respectively installed and fixed to the four mounting frames 2, so that when the four photoelectric sensors 8 accurately locate and detect that the soap blank has moved to the lower end of the stamping die 7, the conveyor belt 5 is turned off so that the soap blank can stay at the lower end of the stamping die 7.

[0025] In order to clamp and lock the position of the soap blank before stamping, guide grooves 10 are provided inside both ends of the hollow base 1. Push plates 12 are slidably connected to the inner side of the two guide grooves 10. A partition 13 is fixed at the center of the inner side of the hollow base 1. A dual-axis motor 14 is installed at the center of the partition 13. Screws 15 are fixed at the two output ends of the dual-axis motor 14. The two push plates 12 are located outside the two screws 15 and are threadedly connected to the screws 15. The two screws 15 are symmetrically arranged. A positioning component is provided between the two push plates 12 and at the upper end of the conveyor belt 5.

[0026] Specifically, the positioning component includes a gap-filling base 17. Two gap-filling bases 17 are arranged between the two push plates 12 and at the upper end of the conveyor belt 5. The two gap-filling bases 17 are symmetrically arranged. A baffle plate 18 is fixed to the upper end of each gap-filling base 17. An electric telescopic rod 19 is installed inside each baffle plate 18. An arc-shaped pressure plate 20 is fixed to the telescopic end of the electric telescopic rod 19. The two arc-shaped pressure plates 20 are symmetrically arranged.

[0027] In order to connect the two push plates 12 to the two gap-filling bases 17 respectively, so that when the two push plates 12 move closer to each other, they can drive the two gap-filling bases 17 to move closer to each other synchronously, the upper ends of the two push plates 12 at the points where they move closer to each other are symmetrically fixed with connecting rods 16, and each pair of connecting rods 16 are fixed to the gap-filling base 17.

[0028] In order to further guide the movement of the push plate 12 and improve its movement stability, each guide groove 10 is symmetrically provided with guide posts 11 on the inner side. The guide posts 11 are fixed to the hollow base 1, and the push plate 12 is slidably connected to the guide posts 11. To ensure the overall stability of the device, rubber feet 9 are fixed at the four corners of the bottom of the hollow base 1.

[0029] Working principle: When the soap blank stops at the lower end of the stamping die 7, before the stamping starts, the dual-shaft motor 14 is started to drive the two screws 15 to rotate. The screws 15 are connected to the push plate 12 by threads, and the guide post 11 guides the push plate 12 to move closer to each other. Then, the two gap filling bases 17 scoop up the soap blank and cooperate with the two baffle plates 18 to block it, so that the soap blank is finally clamped between the two baffle plates 18.

[0030] At this time, the two electric telescopic rods 19 are activated to drive the two arc-shaped pressure plates 20 to move closer to each other. The two arc-shaped pressure plates 20 are used to clamp the two sides of the soap blank, and finally complete the limiting and locking of the soap blank. At this time, the telescopic cylinder 6 is activated to move the stamping mold 7 down to facilitate precise stamping. After the stamping is completed and the clamping of the soap blank is released, the conveyor belt 5 is restarted to output it outward.

[0031] It should be noted that the device structure and accompanying drawings of this utility model mainly describe the principle of this utility model. In terms of the technical aspects of this design principle, the setting of the power mechanism, power supply system and control system of the device is not fully described. However, under the premise that those skilled in the art understand the principle of the above utility model, the power mechanism, power supply system and control system can be clearly understood. The control method in the specific application document is automatic control through a controller. The control circuit of the controller can be implemented by those skilled in the art through simple programming.

[0032] All standard parts used can be purchased from the market, and can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the existing technology. The machinery, parts and equipment adopt conventional models in the existing technology.
