DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to 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 the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0023] The conveyor is a device for conveying materials from one place to another by means of transmission devices based on mechanical, hydraulic and pneumatic principles. According to different conveying methods, the conveyor can be divided into belt conveyor, roller conveyor and chain conveyor. Each type of conveyor has its unique advantages in different application occasions.

[0024] Based on the technical defects that the material needs to be manually put back to the original position and the running speed is constant in the prior art, please refer to Figures 1-4The conveyor multi-section speed operation device provided by the utility model does not need students to manually put the materials back to the original position, can improve the practical training efficiency of students, has the function of multi-section speed demonstration, facilitates students to observe the transportation state of the materials under different speeds, and thus improves the practical training effect, the device comprises a bottom plate 1, a plurality of support frames 2 are installed on the bottom plate 1, a plurality of support frames 2 are installed on the body 3, the inner sides close to the two ends of the body 3 are rotationally connected with driving rollers 4 and driven rollers 5 respectively, a conveying belt 6 is transmissionally connected between the driving roller 4 and the driven roller 5, one side of the body 3 is provided with a driving unit 7 connected with the driving roller 4, and one side of the body 3 close to the driven roller 5 is provided with a reset mechanism 8 installed on the bottom plate 1; when in use, students place the materials in the downcomer 10 inside the fixing frame 9, the materials fall onto the conveying belt 6 through the downcomer 10, then the driving unit 7 works and drives the driving roller 4 to drive the conveying belt 6 to move, the conveying belt 6 moves horizontally with the materials, when the materials pass through the photoelectric sensors 13 at different positions, the materials can move at different speeds, thus facilitating students to observe the conveying state of the materials under different speeds, and the materials after being conveyed are returned to the initial position under the action of the reset mechanism 8, thus facilitating the practical training use of the next student.

[0025] When the existing conveyor is used, the materials need to be manually placed to the original position by students after moving to one side along the conveying belt 6, so as to facilitate the use of the next student, but manual placement every time is time-consuming and laborious, thus affecting the practical training efficiency of the students. Figure 2 and Figure 3 The reset mechanism 8 comprises a guide chute 801 arranged directly below the body 3, the guide chute 801 is installed in an inclined manner on the bottom plate 1, one end of the guide chute 801 is located at the outer side of the driving roller 4, an electric push rod 802 is installed on the side wall of the other end of the guide chute 801, a push plate 803 is fixedly arranged on the telescopic shaft of the electric push rod 802, and a lifting assembly 804 is arranged on the side of the other end of the guide chute 801 away from the electric push rod 802.

[0026] Since the fallen materials are located at the bottom of the guide chute 801, the materials cannot be moved to the position of the fixing frame 9, and the students still have the problem of inconvenience in taking, for solving the problem, please refer to Figure 3The lifting assembly 804 comprises a lifting groove 8041 fixed to the side wall of the material guide groove 801, a motor 8942 is installed on the side wall near the top of the lifting groove 8041, a linear lead screw 8043 is fixed to the output shaft of the motor 8942, the linear lead screw 8043 is rotationally connected to the side wall of the lifting groove 8041, a sliding block 8044 is screwingly and drivably connected to the linear lead screw 8043, the sliding block 8044 is slidingly arranged in a guide hole formed in the side wall of the lifting groove 8041, and a supporting plate 8045 is fixed to the sliding block 8044; after the material is pushed into the lifting groove 8041, the material can fall on the supporting plate 8045, then the motor 8942 is operated to drive the linear lead screw 8043 to rotate, the linear lead screw 8043 drives the supporting plate 8045 to move upward through the screwing drive of the sliding block 8044, and the material on the supporting plate 8045 is moved to the height of the fixing frame 9, so that the next student can directly take the material and put it into the feeding pipe 10, and the device has the advantage of convenient use.

[0027] When the material rolls to the bottom of the material guide groove 801, the material is not arranged neatly, which causes the problem of collapse when the subsequent material is reset. To solve the problem, an arc-shaped groove 8011 is arranged at the bottom of the other end of the material guide groove 801, and a through hole 8012 is formed in the side wall of the material guide groove 801 near the groove 8011; when the material rolls into the groove 8011, the material can fall into the lifting groove 8041 along the through hole 8012 under the limiting action of the groove 8011, so that each material is arranged neatly when stacked and the problem of collapse does not occur.

[0028] In use, the student can directly put the material into the feeding pipe 10, and then the material falls on the conveying belt 6 under the action of gravity, but when falling, the material tilts outward and rolls off the conveying belt 6. To avoid the problem, the fixing frame 9 is installed on the machine body 3 near the lifting assembly 804, the inner side of the fixing frame 9 is fixed with the feeding pipe 10 and the limiting frame 11, and the limiting frame 11 is below the feeding pipe 10; the limiting frame 11 limits the space below the feeding pipe 10, so that the material can fall stably.

[0029] The running speed of the existing conveyor is constant, but in actual production, the material conveying often needs to be adjusted according to the production rhythm, so it is difficult to achieve the training effect. To solve the problem, a plurality of mounting frames 12 are installed on the machine body 3, and a photoelectric sensor 13 is installed on the top of each mounting frame 12; when the material passes through the photoelectric sensor 13 after coming out of the discharge pipe, the photoelectric sensor 13 senses the material signal, and sends the signal to the driving unit 7 and changes the rotating speed of the driving unit 7, so that the material moves at different speeds when passing through different photoelectric sensors 13, has the function of multi-speed demonstration, and is convenient for students to observe the transportation status of the material at different speeds, thereby improving the training effect.

[0030] To ensure that students can visually see the transport of materials on the conveyor belt 6, an observation platform 14 is also installed on the base plate 1.

[0031] It is to be understood that the terms "including", "comprising", or any other variation thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can include other elements not expressly listed or inherent to such process, method, article, or apparatus.
