Description

Belt conveying system and belt deflection adjusting device

The invention relates to a transportation system for conveying materials, in particular to a belt conveying system and a belt deflection adjustment device.

Referring to Figure 1, an existing belt feeding device 1 includes a plurality of supporting wheel units 11 arranged at intervals along a conveying direction, a belt 12 arranged on the supporting wheel units 11 and suitable for conveying materials, and a plurality of feeding The belt 12 is wound around and used for operation to provide a pulley 13 for driving the belt 12 to move, and a centering unit 14 arranged at a distance from the belt 12 and used for guiding the belt 12 to move along the conveying direction. The belt 12 has a material-bearing surface 121 located on the outside and suitable for carrying materials, and a non-material-bearing surface 122 opposite to the material-bearing surface 121 and contacting the pulleys 13. It is defined that the bearing surface 121 of the belt 12 is in a bearing state when it is above the pulleys 13 and is in a return state after moving below the pulleys 13. Wherein, the centering unit 14 is set at a position lower than the belt pulleys 13, that is, at the position where the bearing surface 121 is in the return state, the centering unit 14 includes a bracket 141 that is set on the ground and extends upward. , A roller 142 erected on the bracket 141 and used to support the belt 12, and two are spaced apart from each other in a transverse direction perpendicular to the conveying direction, and used to contact the belt 12 to drive the roller 142 to guide the The side pressure roller mechanism 143 where the belt 12 moves.

When the belt 12 is driven by the pulleys 13 when it deviates from the preset conveying direction, after conveying the carried material to the target position, the bearing surface 121 is in the return state , Will pass the centering unit 14 located relatively downstream. Since the side pressure roller mechanisms 143 have been set in advance along the transverse direction to match the width of the belt 12 to set appropriate spacing, if the belt 12 is offset along the transverse direction, it will contact the set on the side where the offset occurs. The side pressure roller mechanism 143 on the same side is then pushed laterally by the side pressure roller mechanism 143 that has been fixed in position, thereby producing the effect of guiding the belt 12.

However, since the centering unit 14 is installed on the ground and extends upward, and it is the time when the material bearing surface 121 is in the return state, the belt 12 does not carry materials at this time, so the roller 142 supports the roller 142 upward. In the case of the belt 12, whether the belt 12 actually touches the roller 142 depends entirely on the weight of the belt 12 due to gravity, which is prone to unpredictable shaking during the movement, and it is difficult to stably contact the roller 142. The efficiency of the centering unit 14 is ensured. In addition, because the roller 142 is bound to contact the bearing surface 121 on the relatively outer side of the belt 12, that is, the bearing surface 121 contacts the centering unit 14 in a downward direction, if it is on the bearing surface 121 There are still relatively small materials left, and the materials are particularly likely to be disturbed and fall down after touching the roller 142. If it causes pollution to the roller 142 and the side pressing wheel mechanisms 143 that need to continue to operate, it will affect the smooth operation. The temperature will cause adverse effects, and even the roller 142 may produce unnecessary abrasion, which shortens the service life of the centering unit 14.

Therefore, the object of the present invention is to provide a belt conveying system and a belt skew adjusting device that can ensure the adjustment performance and avoid contamination by the conveyed materials.

Therefore, the belt conveying system of the present invention includes a plurality of supporting wheel devices arranged at intervals along a conveying direction, a power pulley arranged on one side of the supporting wheel devices along the conveying direction, and a power pulley arranged on the conveying direction along the conveying direction. The driven pulley on the opposite side of the power pulley, a conveyor belt wound around the power pulley and the driven pulley and supported by the supporting wheel devices, and a belt skew adjustment of the present invention arranged at intervals from the conveyor belt Device.

The conveyor belt is used for conveying materials along the conveying direction with the driving of the power pulleys, and runs in a return direction opposite to the conveying direction, and includes a bearing surface suitable for carrying materials and located on the outside, and a Contrary to the non-bearing surface of the bearing surface.

The belt deflection adjusting device of the present invention includes a base, a self-aligning roller arranged under the base and used to resist the non-bearing surface of the conveying belt, and two are installed in a transverse direction that is transverse to the conveying direction. The linkage mechanisms on opposite sides of the base and two side pressure wheel modules are respectively connected to the linkage mechanisms and used to drive the linkage mechanisms and the self-aligning roller to move the conveying belt along the conveying direction.

The effect of the present invention is that since the self-aligning roller of the belt deflection adjusting device is suspended on the base and contacts the non-bearing surface of the conveying belt downwards, it can cooperate with the upward support of the conveying belt. Supporting wheel device, both of which press the conveyor belt from opposite sides to ensure the friction force of the self-aligning roller with respect to the conveyor belt, so as to contact the conveyor belt and play a role with good friction. , It also ensures the deflection adjustment function of the belt deflection adjustment device. In addition, since the self-aligning roller is in contact with the non-bearing surface, it will not be disturbed by the fine materials remaining on the bearing surface, which can prevent the fine materials from contaminating the self-aligning roller or the self-aligning roller loses friction. It is possible to maintain the normal operation of the conveyor belt by maintaining the belt skew adjustment device, and it can also prevent the belt skew adjustment device from being worn by fine materials.

2 is a system embodiment of the belt conveyor system of the present invention. The system embodiment includes a plurality of supporting wheel devices 2 arranged at intervals along a conveying direction D, and a supporting wheel device 2 arranged on the supporting wheel devices 2 along the conveying direction D. One side of the power pulley 3, a driven pulley 3'arranged on the opposite side of the power pulley 3 along the conveying direction D, and a driven pulley 3'arranged around the power pulley 3 and the driven pulley 3'. The supporting wheel device 2 supports and conveys the belt 4, and a device embodiment of the belt deflection adjusting device 5 of the present invention arranged at a distance from the conveying belt 4. Among them, each support wheel device 2 is specifically a conveying roller set, and an appropriate number can be set according to the length of the conveying path and the support strength requirements. In addition to supporting the conveying belt 4, it can also be rolled by the rollers. Produce a guiding effect. In addition, the power pulley 3 is connected to a power source (not shown in the figure), which is preferably a motor, and is used to rotate by providing power from the power source to cooperate with the synchronous rotation of the driven pulley 3', thereby driving The conveyor belt 4 runs.

The conveying belt 4 is used for conveying materials in the conveying direction D along with the driving of the power pulley 3, and then running in a return direction R opposite to the conveying direction D after conveying the materials. The conveyor belt 4 includes a material-bearing surface 41 which is suitable for carrying materials and is located on the outside, and a non-material-bearing surface 42 opposite to the material-bearing surface 41. Specifically, the material-bearing surface 41 and the non-material-bearing surface 42 are generally referred to as the upper rubber side and the lower rubber side in the relevant industry. The first thing to note is that the conveyor belt 4 must maintain proper tension when transporting materials. If the tension is insufficient and cannot be stretched, it may affect the transportation of the material, and if the tension is too high, it may affect the normal operation of the conveyor belt 4 Service life, so it must be properly adjusted.

2 to 4 at the same time, the device embodiment includes a base 51, a self-aligning roller 52 disposed under the base 51 and used to abut against the non-bearing surface 42 of the conveyor belt 4, two in one The transverse direction T, which is transversely perpendicular to the conveying direction D, is installed on the linkage mechanisms 53 on opposite sides of the base 51, and two are respectively connected to the linkage mechanisms 53 and used to drive the linkage mechanisms 53 and the self-aligning roller 52 And the side pressure roller module 54 which makes the conveying belt 4 move along the conveying direction D. The base 51 is suspended and erected at a position higher than the non-bearing surface 42 of the conveyor belt 4 by an appropriate distance, and has a bracket 511, a rotating shaft 512 extending downward from the bracket 511, and a A rotating frame 513 on the rotating shaft 512 that can rotate relative to the bracket 511 and for the self-aligning roller 52 to install. Adjusting the distance between the base 51 and the conveyor belt 4 can adjust the external force of the self-aligning roller 52 contacting the conveyor belt 4 in accordance with the diameter and width of the self-aligning roller 52, so by adjusting the base 51 Setting the position or even changing the selected diameter and width of the self-aligning roller 52 can achieve the effect of adjusting the tension of the conveyor belt 4.

Referring to FIGS. 5 and 6 in conjunction with FIG. 3, each linkage mechanism 53 has a shaft 531 fixed to the bracket 511, and a shaft sleeve 532 set on the shaft 531 and capable of rotating relative to the shaft 531 , A first moment arm 533 connected to the shaft sleeve 532 and extending laterally, a second moment arm 534 connected to the shaft sleeve 532 and extending laterally and sandwiching a fixed angle with the first moment arm 533, and a second moment arm 534 from the The first force arm 533 is bent to extend longitudinally and is connected to the connecting rod 535 of the rotating frame 513, and a second force arm 534 is bent and extends longitudinally, and is provided for the installation of the individual side roller modules 54 Bearing rod 536. The connecting rod 535 and the bearing rod 536 of each linkage mechanism 53 extend in the longitudinal direction. Therefore, when the first force arm 533 or the second force arm 534 is an external force as the lever arm, the lever will be exerted. As a result, the sleeve 532 is driven to rotate relative to the shaft 531. Also, because the connecting rod 535 is connected to the rotating frame 513, and the carrying rod 536 is connected to the individual side roller modules 54, the rotating frame 513 or the individual side roller modules 54 receive In the case of external force, mutual linkage will be generated due to the arrangement of the linkage mechanism 53.

When the system embodiment is operating, the power pulley 3 and the driven pulley 3'work together to drive the conveyor belt 4 to run, and then the material receiving surface 41 is used to transport materials. Because the side roller modules 54 are spaced apart from each other on the opposite sides of the conveyor belt 4 along the transverse direction T, and each side roller module 54 is adjusted in advance to be the same as the conveyor belt 4 The sides are separated by an appropriate distance. In the process of conveying materials, if the conveyor belt 4 deviates from the conveying direction D (see Figure 2), or the return position deviates from the return direction R opposite to the conveying direction D, Then the conveyor belt 4 will contact one of the side pressure roller modules 54 located on the same side as the deviation side. When the conveyor belt 4 is in contact with one of the side roller modules 54, if the degree of deviation is slight, it will reverse and be corrected when it touches the side roller module 54; but if the degree of deviation is The side pressure wheel module 54 has been pushed. When the side pressure wheel module 54 receives an outward pushing force, the second moment arm 534 will be used as a moment arm to generate a moment relative to the shaft 531 to drive the The second moment arm 534 clamps the first moment arm 533 at a fixed angle to rotate relative to the shaft 531, thereby driving the rotating frame 513 and the spherical roller 52 to rotate toward the center, so that the spherical roller 52 generates a guide The effect of the conveyor belt 4 is right.

It should be particularly noted that since the spherical roller 52 of the device embodiment is suspended on the base 51 to contact the non-bearing surface 42 of the conveyor belt 4, it can be used on the non-receiving surface 41 of the conveyor belt. Under the circumstance, the conveying belt 4 is supported to maintain proper tension, and the fine materials remaining on the bearing surface 41 will not be disturbed, and the possibility of fine materials contaminating the self-aligning roller 52 can be avoided. Exerting the function of guiding the conveyor belt 4 in the normal embodiment of the device, it also prolongs the service life of the device embodiment while avoiding the abrasion of fine materials. In addition, because the self-aligning roller 52 of the device embodiment is in contact with the non-receiving surface 42 of the conveyor belt 4 from top to bottom, compared to the prior art that only relies on the weight of the conveyor belt 4 to contact downwards. In other words, it can be properly adjusted at the time of installation to ensure that the self-aligning roller 52 is in contact with the conveyor belt 4 with a proper supporting force, and not only can be used to cooperate with the supporting roller devices 2 to resist from opposite sides. Pressing the conveyor belt 4 enables the conveyor belt 4 to maintain proper tension during operation, and to ensure that the conveyor belt 4 can stably contact the self-aligning roller 52 to maintain a certain frictional force to allow the conveyor belt 4 to operate normally, avoiding Due to unexpected floating, the guiding effect of the device embodiment on the conveyor belt 4 is affected.

Referring to Fig. 7 and in conjunction with Fig. 3, considering that the conveying belt 4 of this embodiment of the system may rotate in the opposite direction and convey materials in the opposite direction, the linkage mechanisms 53 are detachably installed on the base 51, so the The interlocking mechanism 53 can change the installation direction according to the requirements of the direction of operation. Among them, the second force arm 534 of each linkage mechanism 53 is substantially in the same direction as the return direction R, so that the individual side pressure roller module can be made to be driven by the operating direction of the conveying belt 4 as a reference. 54 is arranged at the relatively front of the base 51 to exert the function of guiding the operation of the conveying belt 4 in the embodiment of the device.

In summary, the belt conveyor system and the belt skew adjustment device of the present invention adopts the self-aligning roller 52 to contact the non-bearing surface 42 of the conveyor belt 4 in a downward manner, and can cooperate with the supporting wheel devices 2 Support the conveyor belt 4 upwards, and the two press the conveyor belt 4 from opposite sides to ensure that the conveyor belt 4 stably contacts the self-aligning roller 52, maintains sufficient friction force to operate normally, and prevents direct contact The bearing surface 41 is affected by the residual material. Therefore, the adjustment function of the belt deflection adjusting device 5 is exerted to prevent the self-aligning roller 52 from being contaminated and affecting the operation, which not only ensures that the conveyor belt 4 The deflection adjustment effect when the deflection is generated also prolongs the service life of the belt deflection adjustment device 5. Therefore, the purpose of the invention can indeed be achieved.
