[0026] 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.

[0027] Example

[0028] Please see Figures 1-4 The present invention provides the following technical solution:

[0029] A model press-fitting machine with easily adjustable pressure, comprising:

[0030] Pressing table 1, with support rods 2 fixedly connected to the four corners of the upper end of the pressing table 1, and a top plate 3 fixedly connected to the upper end of the multiple support rods 2;

[0031] Hydraulic cylinder 4 is fixedly connected to the lower end of the top plate 3;

[0032] The first pressure plate 6 is fixedly connected to the extended end of the hydraulic cylinder 4;

[0033] The second pressure plate 7 is located below the first pressure plate 6 and is slidably connected to the first pressure plate 6 and the hydraulic cylinder 4.

[0034] Multiple springs 8 are provided, and all springs 8 are fixedly connected to the upper end of the second pressure plate 7 and the lower end of the first pressure plate 6.

[0035] In a specific embodiment of this utility model, the pressing table 1 has an internal cavity structure for storing some items. The support rod 2 supports the top plate 3. The hydraulic cylinder 4 is fixedly connected to the lower end of the top plate 3. When the hydraulic cylinder 4 is running, it drives the first pressure plate 6 connected to its extended end to move downward. The first pressure plate 6 drives the second pressure plate 7 to move downward and contact the chemical molecular model. Pressure is provided by the hydraulic cylinder 4 to press the model. The hydraulic cylinder 4 uses a hydraulic system to adjust the pressure, achieving a wider pressure range and more precise pressure control, which facilitates pressure adjustment. When the second pressure plate 7 presses on the surface of the model, the elastic force of the spring 8 buffers the pressure on the model, preventing damage caused by excessive pressure. A groove is provided at the extended end of the hydraulic cylinder 4, and a sliding rod is integrally formed at the upper end of the second pressure plate 7. The sliding rod is slidably connected in the groove for buffering the second pressure plate 7. By using this device, under the elastic force of the spring 8, the pressure of the hydraulic cylinder 4 is prevented from being too high and damaged during model pressing, thereby improving the yield of chemical model processing.

[0036] Please refer to the details. Figures 1-4 The first pressure plate 6 and the second pressure plate 7 each have multiple light-transmitting holes 901, and multiple infrared emitters 9 are fixedly connected inside the first pressure plate 6.

[0037] In this embodiment, the light-transmitting hole 901 is used for the infrared light generated by the infrared emitter 9 to pass through. The infrared light shines on the surface of the pressing table 1 through the light-transmitting hole 901. The operator positions the second pressing plate 7 according to the multiple infrared lights, which makes it convenient to adjust the position of the model to be pressed and facilitates the processing of the chemical molecule model.

[0038] Please refer to the details. Figures 1-4 The pressing table 1 is equipped with a clamping mechanism, which includes two slides 10, screws 11, motors 12 and clamping plates 13. The two slides 10 are both opened at the upper end of the pressing table 1. The two clamping plates 13 are slidably connected in the two slides 10. The two screws 11 are rotatably connected in the two slides 10 respectively. The two screws 11 are threadedly connected to the two clamping plates 13. The two motors 12 are fixedly connected to one side of the surface of the pressing table 1. The output ends of the two motors 12 are respectively fixed to the ends of the two screws 11.

[0039] In this embodiment: the clamping mechanism is used to clamp the chemical molecule model and improve the stability of the clamping. When the motor 12 is running, it drives the screw 11 connected to its output end to rotate. When the screw 11 rotates, it drives the clamping plate 13 to slide in the slide groove 10. The threads on both sides of the surface of the screw 11 are opposite. When the screw 11 rotates, it drives the two clamping plates 13 to move towards each other or away from each other, so as to achieve the clamping effect of the chemical molecule model.

[0040] Please refer to the details. Figures 1-4The surface of the pressing table 1 is hinged to a door panel 14 via a hinge shaft, and a handle is fixedly connected to the surface of the door panel 14.

[0041] In this embodiment: after some items are placed inside the pressing table 1, the door panel 14 is closed to the pressing table 1 to protect the items. The handle is used to make the door panel 14 rotate around the hinge axis.

[0042] Please refer to the details. Figures 1-4 Each of the four corners of the lower end of the pressing table 1 is fixedly connected with a support leg 15.

[0043] In this embodiment, the support leg 15 serves to support the pressing table 1.

[0044] Please refer to the details. Figures 1-4 Multiple fixing plates 5 are fixedly connected to the lower end of the top plate 3, and all the fixing plates 5 are connected to the hydraulic cylinder 4.

[0045] In this embodiment, the fixing plate 5 is used to improve the stability of the hydraulic cylinder 4 during installation.

[0046] It should be noted that the specific models of hydraulic cylinder 4, infrared transmitter 9, and motor 12 used shall be selected by those skilled in the art. Furthermore, the hydraulic cylinder 4, infrared transmitter 9, and motor 12 mentioned above are all existing technologies and will not be elaborated upon in this solution.

[0047] The working principle and usage process of this utility model are as follows: When using this device, the chemical molecule model to be pressed is first placed between two clamping plates 13. The placement position of the chemical molecule model is adjusted according to the infrared light emitted by the infrared emitter 9 onto the surface of the pressing table 1. After adjustment, the clamping mechanism is controlled to operate, and the model is clamped by the two clamping plates 13. Then, the hydraulic cylinder 4 is controlled to operate. The extended end of the hydraulic cylinder 4 indirectly drives the second pressure plate 7 to move down and contact the chemical molecule model, thus pressing the chemical molecule model. By using this device, under the elastic force of the spring 8, the pressure of the hydraulic cylinder 4 is prevented from being too high and damaged during model pressing, thereby improving the processing yield of the chemical model.

[0048] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
