For example, a pipe clamp can be used to fix the position of the roller, and a wheel axle, a hook, a rotating shaft, a pulley, etc. can meet different transmission or connection requirements.

[0003] However, without exception, the belt rollers in the prior art are designed according to the models of the belt rollers, especially the angle between the middle roller and the side rollers, which is determined by the frame and cannot be adjusted. This leads to certain deficiencies when conveying powder materials or materials with larger monomer volumes. For example, if the angle between the side roller and the middle roller is too small, the belt will bend more, which is not conducive to the stable conveying of materials with larger monomer volumes. If the angle between the side roller and the middle roller is too large, the belt will bend less and be relatively flat, but when conveying powder materials, it may cause the powder materials to be lost under the action of airflow.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process.

[0019] The belt rollers in the prior art are all designed according to the models of the belt rollers, especially the angle between the middle roller and the side rollers, which is determined by the frame and cannot be adjusted. This leads to certain deficiencies when conveying powder materials or materials with larger monomer volumes. For example, if the angle between the side roller and the middle roller is too small, the belt will bend more, which is not conducive to the stable conveying of materials with larger monomer volumes. If the angle between the side roller and the middle roller is too large, the belt will bend less and be relatively flat. However, when conveying powder materials, it may cause the powder materials to be lost under the action of airflow.

[0020] In view of this, the utility model provides a belt roller structure, which realizes that the angle of the side roller can be adjusted within a certain range through the cooperation between the side roller support plate, the first support, the second support and the limiting unit, and is stabilized by the limiting unit, so that it can be adjusted according to the actual situation of the conveyed material. For example, if the volume of the material monomer is large, the side roller can be rotated to make the angle formed by the side roller and the horizontal plane smaller, and the side roller and the middle roller are closer to a straight line. In this way, the contact area between the material with a large monomer volume and the belt can be larger, thereby improving the stability of conveying. For example, if the material is powder, the angle formed by the side roller and the horizontal plane can be larger, that is, the angle between the side roller and the middle roller is smaller. In this way, during the conveying of powder material, the depth of the belt bending can be increased, and the loss of powder material due to air flow can be reduced to a certain extent.

[0021] Depend on Figure 1 and Figure 2 It can be seen that a belt roller structure in this case includes a middle roller 1, and side rollers 2 are arranged on both sides of the middle roller 1; a side roller support plate 3 is arranged at the bottom of the side roller 2, one end of the side roller 2 is rotatably connected to the first support 4 through a bearing, the bottom of the first support 4 is rotatably connected to the top of the side roller support plate 3 through a pin shaft, and the end of the side roller 2 away from the first support 4 is rotatably connected to the second support 5 through a bearing, and a limiting unit is arranged at the bottom of the second support 5.

[0022] In the specific implementation process, it is worth pointing out that the middle roller 1 and the side rollers 2 are respectively supported on the bottom and both sides of the bottom of the belt, so that the belt forms a trapezoidal shape for conveying materials. The side roller support plate 3 and the first support 4 cooperate so that the inclination angle of the side roller 2 can be adjusted within a certain range, which can change the shape of the belt and facilitate the conveying of materials of different volumes and properties. For example, if the volume of the material monomer is large, the side roller 2 can be rotated to make the angle formed by the side roller 2 and the horizontal plane smaller, and the side roller 2 and the middle roller 1 are closer to a straight line. In this way, the contact area between the material with a large monomer volume and the belt can be larger, thereby improving the stability of conveying. For example, for powder materials, the angle formed by the side roller 2 and the horizontal plane can be larger, that is, the angle between the side roller 2 and the middle roller 1 is smaller. In this way, during the conveying of powder materials, the depth of the belt bending can be increased, which can reduce the loss of powder materials caused by air flow to a certain extent. The purpose of the limiting unit is to support the bottom of the second support 5 to facilitate the maintenance of the angle after adjustment.

[0023] In one practicable manner, see Figure 2 The limiting unit includes a roller 6, a support seat 7, a groove 8 and a limiting rail 9; a plurality of grooves 8 are opened on the top of the support seat 7, a roller 6 is fitted into one groove 8, and the roller 6 is rotatably connected to the bottom of the second support seat 5 through a bearing, and the bottom of the support seat 7 is slidably clamped with a limiting rail 9 fixed to the surface of the side roller support plate 3.

[0024] During the specific implementation process, it is worth pointing out that the purpose of setting the roller 6 is to reduce the friction between the support seat 7 and the second support seat 5, which is conducive to pushing the support seat 7 to move along the outer wall of the limiting rail 9. When the groove 8 is designed, it can play a certain limiting role between the roller 6 and the support seat 7. It can be understood that the side roller 2 has a tendency to drive the second support 5 to move downward under its own gravity and the pressure of the upper belt. Therefore, through the support of the support seat 7 and the limitation of the roller 6 and the groove 8, the support of the side roller 2 can be fully achieved. In order to facilitate the adjustment of the position of the support seat 7, the cross-section of the limiting rail 9 can be rectangular, which is convenient for removing the support seat 7 directly from the top of the limiting rail 9.

[0025] Furthermore, the limiting unit also includes a slot 10 and an insertion rod 11. A plurality of insertion rods 11 are provided and fixedly connected to the top of the limiting rail 9 at equal distances. The insertion rod 11 located inside the support seat 7 is inserted into the inside of the support seat 7 through the slot 10.

[0026] In the specific implementation process, it is worth pointing out that the cooperation between the slot 10 and the insertion rod 11 can further fix the limit rail 9 and the support seat 7 to ensure stable support of the second support 5 by the support seat 7.

[0027] In one practicable manner, see Figure 1 and Figure 3 A middle roller support plate 12 is provided at the bottom of the middle roller 1, and third supports 13 are fixedly connected to both sides of the top of the middle roller support plate 12. The third support 13 is rotatably connected to the end surface of the middle roller 1 through a bearing, and a mounting bracket 23 is fixedly connected to the bottom of the middle roller support plate 12.

[0028] In the specific implementation process, it is worth pointing out that the function of the third support 13 is to fix the middle roller 1 and the middle roller support plate 12, and the mounting bracket 23 is used to facilitate fixing the belt roller structure on the frame or other carriers for installation.

[0029] Furthermore, a sleeve plate 14 is fixedly connected to the bottom of the middle roller support plate 12 , and plug plates 15 are inserted on both sides of the inner wall of the sleeve plate 14 , and the ends of the plug plates 15 are fixedly connected to the bottom of the side roller support plate 3 .

[0030] In the specific implementation process, it is worth pointing out that the sleeve plate 14 limits the plug plate 15 to ensure that the side roller support plate 3 and the middle roller support plate 12 are located at the same height and the same front and rear position. The plug-in length of the sleeve plate 14 and the plug plate 15 can be adjusted according to the width of the belt to change the spacing between the side rollers 2 and the middle roller 1, thereby improving the adaptability of the belt roller structure to belts of different specifications. Of course, in order to ensure the normal working effect of the belt conveyor, the method of adjusting the spacing between the side rollers 2 and the middle roller 1 is only applicable to the case where the original roller structure is damaged and it is difficult to replace the roller of matching size in a short time. It can be used in a short term to ensure the operation of the belt conveyor. If it is used for a long time, it should depend on the actual situation.

[0031] In one practicable manner, see Figure 3 and Figure 4 A U-shaped fixing rod 17 is provided below the middle roller support plate 12. Both ends of the U-shaped fixing rod 17 penetrate the bottom of the sleeve plate 14 and are movably connected to the sleeve plate 14. The end of the U-shaped fixing rod 17 is inserted into the bottom of the plug plate 15 through the vertical groove 16. An inclined opening 18 is provided on the surface of the U-shaped fixing rod 17. A round rod 19 is movably connected to the inner wall of the inclined opening 18. The outer wall of the round rod 19 is fitted to the inner wall of the inclined opening 18 through a limiting groove 20 provided at the top of the inner wall of the inclined opening 18. A slider 21 located on the back of the U-shaped fixing rod 17 is fixed to the back of the round rod 19. A slide rail 22 is slidably clamped on the top of the slide rail 21. The slide rail 22 is fixed to the bottom of the sleeve plate 14.

[0032] In the specific implementation process, it is worth pointing out that the U-shaped fixing rod 17 fixes the sleeve plate 14 and the plug plate 15 by cooperating with the vertical groove 16, so as to ensure that the relative distance between the rear roller 2 and the middle roller 1 is fixed after adjustment, thereby improving the working stability of the belt conveyor. The limiting groove 20 is opened at the top of the lower end of the inner wall of the inclined opening 18, and the principle of fixing the U-shaped fixing rod 17 with the round rod 19 is as follows: since the U-shaped fixing rod 17 has a tendency to move downward under the action of gravity, the round rod 19 and the limiting groove 20 are not only fitted, but also in a tight relationship. The tight force comes from the gravity of the U-shaped fixing rod 17. When the end of the U-shaped fixing rod 17 needs to be removed from the inside of the vertical groove 16, the plug plate 15 is adjusted. 5, first push the U-shaped fixing rod 17 upwards, so that the inclined opening 18 and the limiting groove 20 move upwards with the U-shaped fixing rod 17, at this time the round rod 19 is disengaged from the inside of the limiting groove 20, at this time the slider 21 is pushed horizontally, the slider 21 drives the round rod 19 to move horizontally, and the movement direction is close to the higher end of the inclined opening 18. In this way, under the joint action of the gravity of the U-shaped fixing rod 17, the U-shaped fixing rod 17 is moved downward and the vertical groove 16 is separated. When the plug plate 15 is adjusted to a suitable position, the slider 21 and the U-shaped fixing rod 17 are restored to their original positions, so that the round rod 19 and the limiting groove 20 are matched, so as to fix the U-shaped fixing rod 17, and at this time the U-shaped fixing rod 17 is inserted into the corresponding vertical groove 16.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
