Description

Technical Field

[0001] The utility model relates to the technical field of safe body sensation, in particular to a safe body sensation mechanical injury roller rolling simulation system. Background Art

[0002] In the field of industrial production, especially in application scenarios involving high-speed rotating machinery and roller equipment, mechanical injury accidents occur from time to time, among which the injuries caused by roller entanglement are particularly serious. In order to increase users' attention to such injuries and improve users' caution during operation, the existing roller entanglement simulation system was born. In the existing roller entanglement simulation system, the positions of the two rollers are fixed, and a certain degree of protection is provided by adding soft materials (such as rubber or sponge) to the outer wall of the roller. However, this protection method seems to be powerless when faced with complex and changeable material forms. When the cross-section of the material exceeds the preset safety range, because the roller spacing is too small and cannot be adjusted in time, even if the outer wall is protected by soft materials, it is impossible to completely prevent the material from being clamped or rolled between the rollers, resulting in serious mechanical injuries.

[0020] The technical solutions in the embodiments of the utility model are clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model. Example 1

[0021] Please refer to the attached Figure 1-6 The present embodiment provides a safe somatosensory mechanical injury roller entrapment simulation system: it comprises a shell 1, a simulation cavity 2 is provided on the upper side of the shell 1, a driving roller 3 is rotatably connected in the simulation cavity 2, an adjusting roller 4 is provided on the upper end of the driving roller 3, both ends of the adjusting roller 4 are rotatably connected with sliders 5, a traction component for applying downward force to the slider 5 is provided on the side of the slider 5, the traction component is located in the shell 1, and a slide groove 6 for the slider 5 to slide is provided on the shell 1.

[0022] A power module is provided in the shell 1, and the power module includes a stepper motor, which is controlled by a PIC module. A start button, a stop button and an emergency stop button for controlling the rotation of the stepper motor are provided at the outer end of the shell 1. The three buttons are located on the side of the simulation cavity 2, and the simulation cavity 2 is located at the upper end of the shell 1. The driving roller 3 and the adjusting roller 4 are both located in the simulation cavity 2. The driving roller 3 is fixedly connected to the stepper motor, and the driving roller 3 is controlled to rotate by the stepper motor. The driving roller 3 and the adjusting roller 4 are made of rubber material. When the two rollers roll on the experiencer, sufficient squeezing force is ensured on the user's hand, and at the same time, the hardness of the driving roller 3 and the adjusting roller 4 is too high to cause pressure injury to the hand. The adjusting roller 4 is supported by sliders 5 on both sides. The sliders 5 at both ends are located in the slide grooves 6 on the shell 1. The traction assembly on the slider 5 has a downward force on the slider 5. In the initial stage, the adjusting roller 4 and the driving roller 3 are in a close fit with each other.

[0023] Slide grooves 6 are provided on both sides of the simulation cavity 2, and the fixed blocks 7 are located in the shell 1. Guide rods 8 are provided on the left and right sides of the adjusting roller 4. Fixed blocks 7 are installed at both ends of the guide rod 8. The fixed blocks 7 are used to support the two ends of the guide rod 8. The slider 5 is sleeved in the middle position of the support rod. The diameter of the through hole 9 on the slider 5 exceeds the diameter of the guide rod 8. The guide rod 8 guides the sliding of the slider 5. When the object is squeezed in the middle of the driving roller 3 and the adjusting roller 4, the adjusting roller 4 drives the slider 5 to move along the direction fixed by the guide rod 8.

[0024] During the squeezing experience, in order to increase the downward force of the adjustment roller 4, a spring 10 is installed on the upper end of the slider 5. As the slider 5 moves upward, the elastic force of the spring 10 on the slider 5 will gradually increase, thereby increasing the downward force of the adjustment roller 4, thereby achieving the effect of somatosensory simulation.

[0025] Furthermore, in order to improve the safety of the device and avoid crushing injuries, a threaded groove is opened at the upper end of the guide rod 8, and the stop block 11 is threadedly connected to the guide rod 8 through the threaded groove. The initial length of the spring 10 is adjusted by moving the stop block 11, and the pressure of the spring 10 on the slider 5 is changed when the initial position is changed, thereby avoiding excessive pressure on the adjustment roller 4 at the beginning.

[0026] Furthermore, in order to ensure safety, the guide rod 8 is threadedly connected to the fixed block 7, and the reversing gear set 12 is composed of two bevel gears meshing with each other. One end of the control rod 13 that drives the reversing gear set 12 to rotate is located outside the housing 1, and the rotation of the control rod 13 can be manually adjusted by the handle. When in use, the stopper 11 is located near the upper fixed block 7. At this time, the spring 10 is in a non-compressed or extended state. When the object is squeezed in the middle of the adjustment roller 4 and the driving roller 3, the squeezing force is the minimum. During the squeezing process, the reversing gear set 12 is driven by rotating the handle and the control rod 13. Rotate, the reversing gear set 12 rotates to drive the guide rod 8 to rotate, the guide rod 8 is threadedly connected with the block 11, and the block 11 is slidably connected with the shell 1. Under the rotation of the guide rod 8, the block 11 moves downward along the guide rod 8, thereby compressing the spring 10, so that the spring 10 has an outward elastic force at both ends. As the block 11 gradually moves downward, the pressure of the spring 10 on the slider 5 gradually increases, so that the force of the adjusting roller 4 on the lower end extrusion material gradually increases. When there is discomfort, the rotation of the control lever 13 can be stopped at any time, so that the experiencer has different experiences from light to heavy, while ensuring the safety of the experience process. Example 2

[0027] The structure is the same as the above embodiment. Figure 7 As shown, the specific difference of this embodiment is that a pulley 14 is rotatably connected to the fixed block 7 at the lower end of the guide rod 8, and the traction assembly includes a traction rope 15, which is wound around the pulley 14, one end of the traction rope 15 is fixedly connected to the slider 5, and the other end of the traction rope 15 is fixedly connected to a counterweight block 16.

[0028] The number of counterweights 16 can be increased or decreased at will, and the pulley 14 plays a role of reversing, reducing the friction energy consumption of the traction rope 15, and pulling the slider 5 by the deadweight of the counterweight 16. Different from the spring 10 component, the force applied to the slider 5 is stable due to the deadweight of the counterweight 16, and will not be affected by the movement of the slider 5.

[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
