Description

Technical Field

[0001] The utility model relates to the technical field of material conveying, and more specifically, to a driving roller for material conveying. Background Art

[0002] In the existing material conveying, an automatic conveying device is generally used. The automatic conveying device generally includes a motor, a driving roller, driving gears sleeved at both ends of the driving roller, and a driving chain engaged with the driving gears. The motor drives the driving gears to rotate through the driving chain, and then drives the driving roller to rotate, so as to realize the conveying of the material placed on the automatic conveying device through the rotation of the driving roller.

[0003] During the rotation of the driving roller to drive the material forward, the material will pass through the turning point of the automatic conveying device, and the material will be touched by external equipment or staff, so that the material is likely to move on the driving roller under the action of inertia or external impact force. The instability of the position of the material on the driving roller makes the material at risk of falling off the automatic conveying device. Summary of the Utility Model

[0004] In view of the above problems existing in the prior art, the utility model provides a driving roller for material conveying.

[0005] In order to solve the above technical problems, the utility model is solved by the following technical solutions:

[0006] A driving roller for material conveying, which includes a plurality of mounting grooves arranged in the circumferential direction and axial direction of the driving roller, and a stop block with one end extendable out of the mounting groove is arranged in the mounting groove;

[0007] The stop block on the driving roller within the orthographic projection range of the material can be more deeply inserted into the mounting groove under the extrusion of the material, and the stop block outside the orthographic projection range of the material can limit the material on at least one side of the material in the direction perpendicular to the advancing direction of the material.

[0008] Preferably, the other end of the stop block is connected to the mounting groove through a return spring;

[0009] The return spring is used to keep the stop block having a tendency to move out of the mounting groove.

[0010] Preferably, a receiving cavity communicated with the mounting groove is provided inside the driving roller; an airbag is provided in the receiving cavity, and the airbag is used to keep the stop block having a tendency to move out of the mounting groove;

[0011] The stop block can be more deeply inserted into the mounting groove by squeezing the airbag.

[0012] Preferably, the accommodating cavity is open at one end of the driving roller; a detachable cover plate for covering the accommodating cavity is provided at one end of the driving roller.

[0013] Preferably, a through hole communicating with the accommodating cavity is provided on the cover plate; the air inlet of the airbag is connected to the through hole.

[0014] Preferably, one end of the stop block facing the side wall in the rotation direction of the driving roller is provided with an inclined surface;

[0015] When not extruded by the material, one end of the inclined surface extends to the opening of the installation groove on the driving roller, and the other end extends to the end surface of the end of the stop block protruding from the installation groove.

[0016] Preferably, an anti-slip pad is provided on the end surface of the end of the stop block protruding from the installation groove.

[0017] The utility model has at least the following beneficial effects:

[0018] In this application, since the material itself has a certain weight, the material will extrude the stop block, causing the stop block to move towards the inside of the installation groove under the extrusion of the material. As a result, the part of the stop block within the orthographic projection range of the material is more deeply inserted into the installation groove compared to the part of the stop block outside the orthographic projection range of the material. In this state, since the part of the stop block within the orthographic projection range of the material moves towards the inside of the installation groove, the bottom surface of the material is closer to the circumferential side wall of the driving roller compared to the end surface of one end of the part of the stop block outside the orthographic projection range of the material. That is, the end surface of one end of the part of the stop block outside the orthographic projection range of the material is higher than the bottom surface of the material. Therefore, when the material advances, the part of the stop block on the driving roller outside the orthographic projection range of the material can limit the material.

[0027] Embodiment 1

[0028] As Figure 1-2 and Figure 5 shown, this embodiment provides a driving roller for material conveying. A plurality of installation grooves 110 are provided on the circumferential outer wall of the driving roller 100, and the plurality of installation grooves 110 are arranged along the circumferential direction and the axial direction of the driving roller 100. A stopper 120 is arranged in the installation groove 110, and one end of the stopper 120 extends out of the installation groove 110, so that one end of the stopper 120 protrudes from the circumferential side wall of the driving roller 100.

[0029] Further, the stopper 120 disposed in the installation groove 110 can move in the radial direction of the driving roller 100 in the installation groove 110. When the material 10 is placed on the driving roller 100, due to the certain weight of the material 10 itself, the material 10 will squeeze the stopper 120, causing the stopper 120 to move towards the inside of the installation groove 110 under the squeezing action of the material 10. As a result, part of the stopper 120 within the orthographic projection range of the material 10 extends deeper into the installation groove 110 compared to the part of the stopper 120 outside the orthographic projection range of the material 10. In this state, since part of the stopper 120 within the orthographic projection range of the material 10 moves towards the inside of the installation groove 110, the bottom surface of the material 10 is closer to the circumferential side wall of the driving roller 100 compared to the end face of one end of the part of the stopper 120 outside the orthographic projection range of the material 10. That is, the end face of one end of the part of the stopper 120 outside the orthographic projection range of the material 10 is higher than the bottom surface of the material 10. Thus, when the material 10 advances, the part of the stopper 120 outside the orthographic projection range of the material 10 on the driving roller 100 can limit the material 10. It can be understood that the part of the stopper 120 outside the orthographic projection range of the material 10 on a single driving roller 100 is located on at least one side perpendicular to the advancing direction of the material 10, that is, on the left and right sides when the material 10 advances. Therefore, the stopper 120 can limit the material 10 on the left and right sides when the material 10 advances. When the material 10 passes through the turning point of the automatic conveying device and when the material 10 is touched by external equipment or staff, the stopper can prevent the movement of the material 10, thereby avoiding the material 10 from falling off the automatic conveying device and improving safety.

[0030] It should be noted that by arranging multiple stoppers 120 on the driving roller 100, the stopper 120 can limit the material 10 on at least one side of the left and right sides when the material 10 advances.

[0031] Further, the setting of the stopper 120 does not affect the conveying of the material 10. Taking two adjacent driving rollers 100 as an example, when the material 10 moves from one driving roller 100 to another driving roller 100, during the rotation of the other driving roller 100, part of the stopper 120 within the orthographic projection range of the material 10 will contact the material 10 from the bottom of the material 10 and be squeezed by the material 10. Therefore, there will be no situation of hindering the conveying of the material 10.

[0032] In some embodiments, the other end of the stopper 120 extending into the installation groove 110 is connected to the installation groove 110 through a return spring 111, and the return spring 111 can keep the stopper 120 having a tendency to move towards the outside of the installation groove 110.

[0033] Specifically, when the stopper 120 contacts the material 10 and is squeezed by the material 10, the stopper 120 moves towards the inside of the mounting groove 110 by compressing the return spring 111, so that the bottom surface of the material 10 is closer to the circumferential side wall of the driving roller 100 than one end face of the part of the stopper 120 outside the orthographic projection range of the material 10; when the material 10 continues to move forward and no longer squeezes the corresponding stopper 120, at this time, under the action of the return spring 111, the corresponding stopper 120 will move in the opposite direction towards the outside of the mounting groove 110 until one end face of it is flush with one end face of the part of the stopper 120 outside the orthographic projection range of the material 10.

[0034] It can be understood that through the setting of the return spring 111, it can better realize that the stopper 120 can move in the radial direction of the driving roller 100 in the mounting groove 110, and the part of the stopper 120 outside the orthographic projection range of the material 10 can limit the material 10 to prevent the material 10 from falling.

[0035] Embodiment 2

[0036] Combined with Figure 1 and Figure 3-5 As shown, the difference between this embodiment and Embodiment 1 is that: a receiving cavity 101 is provided inside the driving roller 100, and the receiving cavity 101 communicates with the mounting groove 110; a limiting block 121 is provided at the other end of the stopper 120. During installation, the entire stopper 120 is placed in the receiving cavity 101, and then one end of the stopper 120 extends out of the circumferential side wall of the driving roller 100 through the mounting groove 110; an airbag 200 is provided in the receiving cavity 101. After the airbag 200 is inflated, the outer side wall of the airbag 200 can squeeze the other end of the stopper 120, so as to keep the stopper 120 having a tendency to move towards the outside of the mounting groove 110.

[0037] It can be understood that since the limiting block 121 is provided at the other end of the stopper 120, the limiting block 121 can resist against the side wall of the receiving cavity 101, so that the stopper 120 can be prevented from falling out of the mounting groove 110.

[0038] With the arrangement of the airbag 200, when the stopper 120 within the orthographic projection range of the material 10 is squeezed by the material 10, the stopper 120 can squeeze the airbag 200, and the airbag 200 deforms under pressure, so that the stopper 120 can move towards the direction inside the mounting groove 110, making the bottom surface of the material 10 closer to the circumferential side wall of the driving roller 100 than the end face of one end of some stoppers 120 outside the orthographic projection range of the material 10; when the material 10 continues to move forward and no longer squeezes the corresponding stopper 120, at this time the airbag 200 will push the corresponding stopper 120 to move in the opposite direction towards the outside of the mounting groove 110.

[0039] It is worth mentioning that when the stopper 120 within the orthographic projection range of the material 10 is squeezed by the material 10, the stopper 120 squeezes the airbag 200, causing the airbag 200 to deform under pressure. Since the volume of the gas in the airbag 200 is constant, the extrusion force of the airbag 200 on the other end of some stoppers 120 outside the orthographic projection range of the material 10 becomes larger, thereby making the stability of some stoppers 120 outside the orthographic projection range of the material 10 higher, and it is more difficult for the material 10 to break through the corresponding stopper 120 and generate displacement, preferably improving the effect of limiting the material 10 and avoiding the dropping of the material 10.

[0040] Furthermore, during actual use, the volume of the gas in the airbag 200 can be adjusted according to the weight of the conveyed material 10, so that the stopper 120 within the orthographic projection range of the material 10 can be easily squeezed into the mounting groove 110 by the material 10, while ensuring that some stoppers 120 outside the orthographic projection range of the material 10 can have better stability.

[0041] In some embodiments, the receiving cavity 101 is open at one end of the driving roller 100 to facilitate the disassembly and assembly of the stopper 120 and the airbag 200 and facilitate use. A cover plate 130 that is detachable and used to cover the receiving cavity 101 is provided at one end of the driving roller 100.

[0042] Furthermore, the cover plate 130 is threadedly connected to one end of the driving roller 100 to achieve the disassembly and assembly of the cover plate 130 on the driving roller 100.

[0043] When the cover plate 130 is disassembled from the driving roller 100, the disassembly and assembly of the stopper 120 and the airbag 200 in the accommodation cavity 101 can be achieved; when the cover plate 130 is installed on the driving roller 100, at this time, the accommodation cavity 101 is closed, and the airbag 200 is installed in the accommodation cavity 101 with limited space. When the stopper 120 squeezes the airbag 200, the airbag 200 can only deform within the limited space. Specifically, when the stopper 120 within the orthographic projection range of the material 10 squeezes the airbag 200, the airbag 200 will deform at the stopper 120 outside the orthographic projection range of the material 10 and further squeeze the corresponding stopper 120, thereby improving the effect of limiting the material 10.

[0044] In some embodiments, a through hole 131 communicating with the accommodation cavity 101 is provided on the cover plate 130, and the air inlet 210 of the airbag 200 installed in the accommodation cavity 101 is adhesively connected to the through hole 131. During installation, first install the stopper 120 into the installation groove 110 through the accommodation cavity 101, then place the uninflated airbag 200 in the accommodation cavity 101 and install the cover plate 130 on the driving roller 100, and then inflate the airbag 200 through the through hole 131.

[0045] It can be understood that when it is necessary to adjust the gas volume in the airbag 200, the airbag 200 can be directly inflated or deflated through the through hole 131 without disassembling the cover plate 130, which is more convenient to operate and more flexible to use.

[0046] Furthermore, when inflating or deflating the airbag 200 through the through hole 131, the stopper 120 can be pressed to make the stopper 120 squeeze the airbag 200, and the gas volume in the airbag 200 can be judged by the squeezing force feedback from the stopper 120.

[0047] Embodiment 3

[0048] Combined with Figure 1-2 As shown, this embodiment is an improvement based on at least one of Embodiment 1 and Embodiment 2. For a driving roller for material conveying, one end of the stopper 120 extending out of the installation groove 110 is provided with an inclined surface 122. Specifically, one end of the stopper 120 facing the side wall in the rotation direction of the driving roller 100 is provided with an inclined surface 122. When the stopper 120 is not squeezed by the material 10, one end of the inclined surface 122 extends to the opening of the installation groove 110 on the circumferential side wall of the driving roller 100, and the other end of the inclined surface 122 extends to the end surface of one end of the stopper 120.

[0049] During the actual conveying process of the material 10, as the material 10 advances and the driving roller 100 rotates, the stop block 120 within the orthographic projection range of the material 10 can first contact the bottom surface of the material 10 through the inclined surface 122. The inclined surface 122 can play a guiding and orienting role. As the driving roller 100 rotates, the bottom surface of the material 10 can transition from the inclined surface 122 to the end face of one end of the stop block 120, thereby achieving a progressive extrusion of the stop block 120, which can avoid the influence of the stop block 120 on the material 10 and improve the stability of the advancement of the material 10.

[0050] In some embodiments, as shown in Figure 2 a non-slip pad 123 is provided on the end face of the end of the stop block 120 extending out of the mounting groove 110. The non-slip pad 123 can be made of rubber, which can preferably increase the friction force between the stop block 120 and the material 10, so that the material 10 must overcome this friction force to generate displacement, which can preferably improve the stability of the position of the material 10 and avoid the dropping of the material 10.

[0051] In summary, the above are only the preferred embodiments of the present invention. All equivalent changes and modifications made according to the scope of the patent application of the present invention shall fall within the scope covered by the patent of the present invention.
