Description

[0002] When some factories produce and process products, they often use conveying devices to transport multiple products to be processed. Traditional conveying devices mainly include two conveyor belts. The products are overlapped between the two conveyor belts, and the conveyor belts convey the products in one direction. With the development within the factory, the rapid development of product upgrades and diversity, the conveyor lines in the equipment cannot meet the rapid changeover of products. In the past, when replacing different products, because the length (the size overlapped between the two conveyor belts) and width (the size along the transportation direction) of the products are different, the conveyor lines need to be replaced.

DETAILED DESCRIPTION

[0030] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively with reference to the accompanying drawings. The accompanying drawings provide preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0031] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0033] The utility model provides a conveying device, which is mainly used to convey materials that need to be processed. In one embodiment, please refer to Figures 1 to 3 The conveying device includes a transport structure 1, a driving structure 4 and an adjustment structure 2. The transport structure 1 includes a second conveying assembly 12 for simultaneously transmitting in a first direction and two groups of first conveying assemblies 11 disposed on both sides of the second conveying assembly 12. Both the first conveying assembly 11 and the second conveying assembly 12 are provided with conveyor belts for transmitting materials, and the conveyor belts are combined together to form a plurality of material limit positions for limiting the position of the materials.

[0034] It can be foreseen that the conveyor belts of the first conveying component 11 and the second conveying component 12 can be driven synchronously, and the material to be transported can be placed in the material limit position so that the material can be fixed in a position relative to the conveyor belts of the two conveying components. When the conveyor belts of the first conveying component 11 and the second conveying component 12 are driven synchronously, the material can be transported in the first direction.

[0035] The driving structure 4 is used to drive the first conveying component 11 and the second conveying component 12 to transmit simultaneously along the first direction. In the present application, since the first conveying component 11 and the second conveying component 12 can be transmitted simultaneously along the first direction, only one driving structure 4 is required to drive the first conveying component 11 and the second conveying component 12 to transmit.

[0036] The adjustment structure 2 is connected to the two sets of first conveying components 11 and is used to adjust the distance between the two first conveying components 11 in the second direction. It should be noted that the first direction is the conveying direction of the conveyor belt, and the second direction is different from the first direction, but the first direction and the second direction are located on the same conveying plane. In a preferred embodiment, the second direction is perpendicular to the first direction. Please refer to Figure 1 , the X-axis direction shown in the figure is the first direction, and the Y-axis direction is the second direction.

[0037] It should be noted that the second conveying assembly 12 also includes an adjusting assembly 124, which is used to adjust the conveying belt of the second conveying assembly 12 to transmit in the first direction to change the size of the material limit in the first direction. The adjusting assembly 124 is equivalent to a structure that can control the second conveying structure to transmit independently. The adjusting assembly 124 can independently adjust the conveying belt of the second conveying assembly 12 to transmit a predetermined distance in the first direction. At this time, the size of the material limit formed between the first conveying assembly 11 and the second conveying assembly 12 in the first direction also changes accordingly. After transmitting to the predetermined position, the adjusting assembly 124 is used to synchronously transmit the second conveying assembly 12 and the first conveying assembly 11.

[0038] By setting the first conveying assembly 11 and the second conveying assembly 12, a limited material level is formed between the conveyor belts of the first conveying assembly 11 and the second conveying assembly 12, and the product can be placed on the conveyor belt and limited within the limited material level to be conveyed along the first direction. By setting the adjustment structure 2, the spacing between the two first conveying assemblies 11 in the second direction can be adjusted to adjust the size of the limited material level in the second direction so as to adapt to products of different sizes in the second direction. By setting the adjustment assembly 124, the conveyor belt of the second conveying assembly 12 can be adjusted to drive in the first direction so that the conveyor belt of the second conveying assembly 12 drives relative to the conveyor belt of the first conveying assembly 11, thereby adjusting the size of the limited material level in the first direction to adapt to products of different sizes in the first direction. By adjusting the size of the limited material level in the first and second directions, the limited material level can be adapted to the limited position of products of different sizes in the first and second directions, thereby realizing the transportation of products of different sizes, increasing the types / models of transported products, and thereby ensuring rapid model change.

[0039] In addition, since the second conveying assembly 12 includes an adjustment assembly 124, the conveying belt can be adjusted to convey along the first direction through the adjustment assembly 124, and the adjusted second conveying assembly 12 can still convey simultaneously with the first conveying assembly 11. Therefore, the present application solution only needs to set up a set of driving structures 4 to realize the synchronous conveying of materials by the first conveying assembly 11 and the second conveying assembly 12, and the separate adjustment of the second conveying assembly 12 does not require another set of driving structures 4, which saves costs and makes the synchronization of the transmission of the first conveying assembly 11 and the second conveying assembly 12 better because only one set of driving structures 4 is used for driving.

[0040] In one embodiment, see Figures 1 to 3 The transport structure 1 further comprises a driving shaft 13 and a driven shaft 14 which are rotatably arranged, and the driving structure 4 is drivingly connected to the driving shaft 13; the first conveying assembly 11 comprises a first driving conveying wheel 111 connected to the driving shaft 13, a first driven conveying wheel 112 connected to the driven shaft 14, and a first conveying belt 113 connected to the first driving conveying wheel 111 and the first driven conveying wheel 112;

[0041] The second conveying assembly 12 includes a second driving conveying wheel 121 connected to the driving shaft 13 , a second driven conveying wheel 122 connected to the driven shaft 14 , and a second conveying belt 123 connected to the second driving conveying wheel 121 and the second driven conveying wheel 122 .

[0042] The rotation axes of the driving shaft 13 and the driven shaft 14 are perpendicular to the first direction and parallel to the second direction. The driving shaft 13 can drive the first driving conveying wheel 111 to rotate. The first driven conveying wheel 112 is coaxially connected to the driven shaft 14. When the first driving conveying wheel 111 rotates, it can drive the first conveyor belt 113 to transmit between the first driving conveying wheel 111 and the first driven conveying wheel 112.

[0043] Since the second active conveying wheel 121 and the second driven conveying wheel 122 are also connected to the active shaft 13 and the driven shaft 14 respectively, when the active shaft 13 rotates, the second active conveying wheel 121 can be driven to rotate simultaneously, so as to realize synchronous transmission of the second conveying belt 123 and the first conveying belt 113 .

[0044] In one embodiment, see Figures 1 to 3, the adjusting component 124 is used to control whether the second conveying component 12 can be transmitted alone in the first direction. Specifically, in the present application, two adjusting components 124 need to be set, and an adjusting component 124 is connected to each of the second active conveying wheel 121 and the second driven conveying wheel 122, and the adjusting components 124 are respectively connected to the active rotating shaft 13 and the driven rotating shaft 14. The adjusting component 124 has a locking state and a loosening state relative to the active rotating shaft 13 and the driven rotating shaft 14. When in the locking state, the second active conveying wheel 121 can be fixedly connected to the active rotating shaft 13, and the second driven conveying wheel 122 can be fixedly connected to the driven rotating shaft 14, so that when the active rotating shaft 13 rotates, the second conveying belt 123 is synchronously transmitted with the first conveying belt 113; when the adjusting component 124 is in the loosening state, the second active conveying wheel 121 and the second driven conveying wheel 122 can rotate relative to the active rotating shaft 13 and the driven rotating shaft 14, respectively, so as to drive the second conveying belt 123 to be transmitted in the first direction alone.

[0045] More specifically, the adjustment assembly 124 includes an adjustment ring 1241 fixedly connected to the second active conveying wheel 121 and a locking member 1242 rotatably connected to the adjustment ring 1241. The active shaft 13 is passed through the adjustment ring 1241, and an elastic member 1243 is provided between the locking member 1242 and the adjustment ring 1241. In a free state, the elastic member 1243 forces the locking member 1242 to press against the surface of the active shaft 13, and the elastic member 1243 is preferably a spring. At this time, due to the friction between the locking member 1242 and the surface of the active shaft 13, the adjustment ring 1241 can be fixed relative to the active shaft 13.

[0046] It should be noted that in order to increase the friction between the locking member 1242 and the surface of the active rotating shaft 13, some structures that are conducive to increasing the friction can be set on the abutting surface of the locking member 1242, or some structures that are conducive to increasing the friction can be set on the abutting surface of the active rotating shaft 13, or preferably, structures that are conducive to increasing the friction are set on the abutting surfaces of both. The structures that are conducive to increasing the friction include but are not limited to adding a layer of rubber or silicone, or setting the abutting surface to a frosted structure, etc.

[0047] In a specific embodiment, the locking member 1242 includes a toggle portion 12421 and a connecting portion 12422, the connecting portion 12422 is rotatably connected to the adjusting ring 1241 via a connecting shaft 12412, the adjusting ring 1241 is provided with a accommodating hole 12411 near the toggle portion 12421, the elastic member 1243 is disposed in the accommodating hole 12411 and one end of the elastic member 1243 abuts against the connecting portion 12422, and the end of the connecting portion 12422 away from the toggle portion 12421 can abut against the active rotating shaft 13.

[0048] It should be noted that a receiving groove (not shown in the figure) can be provided on the adjusting ring 1241, and the connecting shaft 12412 is preferably perpendicular to the driving shaft 13 or the driven shaft 14, and the connecting shaft 12412 is located in the receiving groove, and the connecting portion 12422 is located in the receiving groove. When the toggle portion 12421 is driven, the connecting portion 12422 can be driven to rotate in the receiving groove. Figure 4 In order to ensure that the connection portion 12422 can be relatively Figure 4 In the state shown, the adjusting ring 1241 rotates clockwise and counterclockwise, and there is a gap between the connecting portion 12422 and the bottom of the receiving groove. Figure 4 When the driving connecting portion 12422 rotates counterclockwise in the direction shown in the figure, the end of the connecting portion 12422 away from the toggle portion 12421 will gradually move away from the active rotating shaft 13. At this time, the adjusting component 124 is in a relaxed state, and the second active conveying wheel 121 can rotate relative to the active rotating shaft 13. When the connecting portion 12422 is loosened, the elastic force of the elastic member 1243 forces the connecting portion 12422 to rotate clockwise until the end of the connecting portion 12422 away from the toggle portion 12421 abuts against the active rotating shaft 13 again, so as to achieve relative fixation of the second active conveying wheel 121 and the active rotating shaft 13.

[0049] It should be noted that the first active conveying wheel 111 and the first driven conveying wheel 112 are respectively sleeved on the active rotating shaft 13 and the driven rotating shaft 14, so that the first active conveying wheel 111 and the first driven conveying wheel 112 can be slidably disposed on the active rotating shaft 13 and the driven rotating shaft 14 respectively along the second direction.

[0050] In order to enable the first active conveying wheel 111 and the first driven conveying wheel 112 to both slide relative to the active rotating shaft 13 and the driven rotating shaft 14 and to be fixed relative to the active rotating shaft 13 and the driven rotating shaft 14, the first active conveying wheel 111 and the first driven conveying wheel 112 need to be detachably connected to the active rotating shaft 13 and the driven rotating shaft 14.

[0051] For example, the first active conveying wheel 111 and the active rotating shaft 13, and the first driven conveying wheel 112 and the driven rotating shaft 14 can be fixedly connected by a keyway structure, or the first active conveying wheel 111 and the active rotating shaft 13, and the first driven conveying wheel 112 and the driven rotating shaft 14 can be fixedly connected by screws, which is determined according to the requirements during design and is not limited here.

[0052] In order to ensure that the moving distances of the first active conveying wheel 111 and the first driven conveying wheel 112 in the second direction are equal and errors are not prone to occur, the first conveying assembly 11 also includes a support rail 114, and the support rail 114 is located between the first active conveying wheel 111 and the first driven conveying wheel 112. The support rail 114 is provided with mounting assemblies 115 at positions close to the first active conveying wheel 111 and the first driven conveying wheel 112. The support rail 114 is rotatably connected to the first active conveying wheel 111 and the first driven conveying wheel 112 through the mounting assemblies 115. It should be noted that the rotating shafts between the support rail 114 and the first active conveying wheel 111 and the first driven conveying wheel 112 are coaxial with the active rotating shaft 13 or the driven rotating shaft 14.

[0053] That is to say, the first active conveying wheel 111 and the first driven conveying wheel 112 can be connected together through the cooperation of the support rail 114 and the mounting assembly 115, which does not affect the rotation of the first active conveying wheel 111 and the first driven conveying wheel 112, but can limit the first active conveying wheel 111 and the first driven conveying wheel 112 from moving synchronously in the second direction to avoid movement errors between the first active conveying wheel 111 and the first driven conveying wheel 112 in the second direction.

[0054] Specifically, the mounting assembly 115 includes a first fixed block 1151 and a second fixed block 1152 which are spaced apart from each other. The first fixed block 1151 and the second fixed block 1152 are both detachably connected to the support rail 114. The first active conveying wheel 111 and the first driven conveying wheel 112 are respectively clamped between the corresponding first fixed block 1151 and the second fixed block 1152. The first fixed block 1151 and the second fixed block 1152 are both connected to a first bearing 1153. The first fixed block 1151 and the second fixed block 1152 are rotatably connected to the first active conveying wheel 111 and the first driven conveying wheel 112 via the first bearing 1153.

[0055] In one embodiment, see Figures 1 to 3 The first conveyor belt 113 is provided with a plurality of first stoppers 1131 spaced apart along its conveying path, and the second conveyor belt 123 is provided with a plurality of second stoppers 1231 spaced apart along its conveying path. In the first direction, there is a gap between the first stoppers 1131 and the second stoppers 1231, and the gap forms a limit dimension of the material limit position along the first direction. The material at the material limit position can be clamped by the two first stoppers 1131 and the one second stopper 1231 in the first direction.

[0056] In one embodiment, the adjustment structure 2 includes a base 21 and two groups of adjustment seats 22 slidably arranged on the base 21 along the second direction. The two groups of adjustment seats 22 are respectively arranged corresponding to the two groups of first conveying components 11. A screw 24 is also threadedly connected to the two adjustment seats 22. The screw 24 has threads with different rotation directions. The screw 24 is connected to different adjustment seats 22 using threads with different rotation directions. A rotating part 25 is also arranged at the end of the screw 24.

[0057] Two rotating connection seats 23 are arranged on the base 21 at intervals, and the two groups of adjustment seats 22 are located between the two rotating connection seats 23. The two ends of the screw rod 24 are respectively rotatably connected to the two rotating connection seats 23. When the rotating member 25 rotates, it can drive the screw rod 24 to rotate relative to the rotating connection seat 23.

[0058] It can be foreseen that when the rotating member 25 is rotated, the screw rod 24 can be driven to rotate, and the adjustment seat 22 can be driven to move along the second direction, and the movement directions of the two adjustment seats 22 are opposite.

[0059] It should be noted that the adjustment seat 22 is specifically fixedly connected to the support rail 114. The adjustment seat 22 includes a support member 221 and a connecting plate 222. The support member 221 is fixedly connected to the connecting plate 222. The connecting plate 222 and the base 21 can be slidably connected by means of a slide rail slider. The end of the support member 221 away from the connecting plate 222 can be detachably connected to the support rail 114.

[0060] For stable movement, the connecting plate 222 and the base 21 are preferably connected by two or more sets of slide rails and sliders. For stable connection, multiple support members 221 can be arranged at intervals on the connecting plate 222, and the multiple support members 221 are simultaneously connected to the support rail 114.

[0061] In one embodiment, the transmission device further includes a support structure 3 provided corresponding to the driving rotating shaft 13 and the driven rotating shaft 14, and the driving rotating shaft 13 and the driven rotating shaft 14 are respectively rotatably connected to the corresponding support structure 3. Specifically, the support structure 3 includes a fixed plate 31 and a plurality of support plates 32 spaced apart on the fixed plate 31, and a second bearing 321 is connected to the support plate 32, and the rotating shaft of the second bearing 321 is parallel to the second direction. The driving rotating shaft 13 and the driven rotating shaft 14 can be respectively connected to the inner ring of the corresponding second bearing 321, so as to be respectively rotatably connected to the corresponding support plate 32 through the second bearing 321.

[0062] It should be noted that the driving structure 4 is integrally mounted on the support plate 32, and the driving structure 4 includes a driving member 41 connected to the support plate 32, a driving wheel 42, a driven wheel 43, and a transmission belt 44 connected between the driving wheel 42 and the driven wheel 43. The driving wheel 42 is coaxially connected to the output end of the driving member 41, and the driven wheel 43 is fixedly connected to the driving shaft 13, and the driven wheel 43 and the driving shaft 13 rotate coaxially. The driving member 41 is preferably a motor, and the driving member 41 can drive the driving wheel 42 to rotate, and under the action of the transmission belt 44, it can drive the driven wheel 43 to rotate, and then drive the driving shaft 13 to rotate.

[0063] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
