[0035] See Figures 1 to 6As shown in the figure, the present utility model discloses a specific embodiment of a width-adjustable conveying device, which includes a mounting frame 1, a conveying mechanism 2 and a pushing mechanism 3. The conveying mechanism 2 includes a first width-adjusting component 21, a first conveying component 22 and a second conveying component 23 mounted on the mounting frame 1. The first conveying component 22 and the second conveying component 23 are arranged in parallel. The first width-adjusting component 21 is drivingly connected to the first conveying component 22 to adjust the width between the first conveying component 22 and the second conveying component 23. The pushing mechanism 3 includes a pushing component 31 and a second width-adjusting component 32 mounted on the mounting frame 1. The pushing component 31 is arranged between the first conveying component 22 and the second conveying component 23. The second width-adjusting component 32 is drivingly connected to the pushing component 31 to adjust the width between the pushing component 31 and the first conveying component 22 and the second conveying component 23.

[0036] Specifically, before conveying the material, the first width-adjusting component 21 adjusts the position of the first conveying component 22 according to the specification of the material to adjust the width between the first conveying component 22 and the second conveying component 23, and the second width-adjusting component 32 adjusts the position of the pushing component 31 to adjust the width between the pushing component 31 and the first conveying component 22 and the second conveying component 23. After adjusting to the appropriate width, the material is placed on the first conveying component 22 and the second conveying component 23, and the first conveying component 22 and the second conveying component 23 move synchronously to convey the material. When the material is conveyed to the end of the conveying mechanism 2, the pushing component 31 pushes the material to continue moving, so that the material can quickly leave the conveying mechanism 2 and be conveyed to the next working station. By adopting the above structure, the conveying device in this embodiment is applicable to conveying various materials with different specifications, and improves the conveying efficiency and the use flexibility of the conveying device.

[0037] See Figures 1 to 3 As shown in the figure, in a specific embodiment, the pushing component 31 is arranged at the middle position between the first conveying component 22 and the second conveying component 23, and the transmission ratio of the first width-adjusting component 21 and the second width-adjusting component 32 is 2:1.

[0038] Specifically, through the above structure, the pushing component 31 is always at the middle position between the first conveying component 22 and the second conveying component 23, and the width between the first conveying component 22 and the second conveying component 23 corresponds to the width of the material, so that when the pushing component 31 pushes the material, it abuts against the middle position of the material. By applying force at the middle position of the material, the stability of the material during movement is improved, effectively preventing the material from tipping or shaking, and the stress distribution is uniform, reducing the bending and deformation of the material. At the same time, the moving direction and speed of the material can be accurately controlled, reducing the error generated during the movement of the material, and also reducing the energy loss to improve the working efficiency, and being applicable to various materials with different shapes and types.

[0039] In a specific embodiment, the first width adjustment assembly 21 includes a first driving lead screw 211 installed on the mounting frame 1, and the first driving lead screw 211 is drivingly connected to the first conveying assembly 22; the second width adjustment assembly 32 includes a second driving lead screw 321 installed on the mounting frame 1, and the second driving lead screw 321 is drivingly connected to the pushing assembly 31.

[0040] Specifically, during the width adjustment process, by driving the first driving lead screw 211 and the second driving lead screw 321 to rotate, the first conveying assembly 22 and the pushing assembly 31 can be moved along the length directions of the first driving lead screw 211 and the second driving lead screw 321, so as to achieve the width adjustment function. The structure is simple and the adjustment is convenient.

[0041] In a specific embodiment, the first width adjustment assembly 21 further includes a width adjustment driving member 212, a first driving sprocket (not shown in the figure), a first driven sprocket (not shown in the figure), a first transmission chain 213, and a third driving lead screw 214 installed on the mounting frame 1. The first driving lead screw 211 is drivingly connected to the width adjustment driving member 212. The first driving sprocket is connected to the first driving lead screw 211. The first transmission chain 213 is drivingly connected to the first driving sprocket and the first driven sprocket. The first driven sprocket is drivingly connected to the third driving lead screw 214. The third driving lead screw 214 is drivingly connected to the first conveying assembly 22. The first driving sprocket and the first driven sprocket have the same structure, so that the first driving lead screw 211 and the third driving lead screw 214 rotate synchronously.

[0042] Specifically, the first driving lead screw 211 and the third driving lead screw 214 are respectively drivingly connected to the end and the front end of the first conveying assembly 22, so that the front end and the end of the first conveying assembly 22 are driven synchronously, so that the width between the front and rear ends of the first conveying assembly 22 and the second conveying assembly 23 is kept consistent. The adjustment is convenient, and the material can be kept stable during the conveying process, avoiding shaking and tilting, thereby reducing the risk of material dropping or damage, and also reducing the risk of material jamming or blocking caused by the inconsistent width between the front and rear ends of the conveying mechanism 2, thereby improving the operation safety; at the same time, the transmission structure composed of the lead screw, the transmission sprocket and the chain is simple and stable, and the transmission efficiency is high. It can be understood that the above width adjustment driving member 212 can be a manual driving member, or an automatic driving member such as a motor or a rotating cylinder.

[0043] In a specific embodiment, the second width adjustment assembly 32 further includes a second driving sprocket (not shown in the figure), a second driven sprocket (not shown in the figure), and a second transmission chain 322. The second driving sprocket is connected to the first driving lead screw 211. The second transmission chain 322 is drivingly connected to the second driving sprocket and the second driven sprocket. The second driven sprocket is connected to the second driving lead screw 321. The tooth number ratio and the radius ratio of the second driving sprocket to the second driven sprocket are 1:2.

[0044] Specifically, by drivingly connecting the second driving wheel in the second width-adjusting assembly 32 to the first driving lead screw 211, during the width-adjusting process, the width-adjusting driving member 212 drives the first driving wheel and the second driving wheel to rotate synchronously through the first driving lead screw 211. The second driving wheel then drives the second driven wheel to rotate through the second transmission chain 322. The tooth number ratio and radius ratio between the second driving wheel and the second driven wheel are both 1:2, so that the rotational speed ratio between the second driving wheel and the second driven wheel is 2:1, enabling the rotational speed ratio between the first driving lead screw 211 and the second driving lead screw 321 to be 2:1. Furthermore, the moving distance ratio between the first conveying assembly 22 and the pushing assembly 31 is 2:1. At the same time, since the pushing assembly 31 is located at the intermediate position between the first conveying assembly 22 and the second conveying assembly 23, the pushing assembly 31 can always be located at the intermediate position between the first conveying assembly 22 and the second conveying assembly 23. Through the above structure, only one width-adjusting driving member 212 can achieve the position adjustment of the first conveying assembly 22 and the pushing assembly 31. The structure is simple and stable, with high transmission efficiency, while improving the energy utilization rate and adjustment efficiency. It can be understood that in other embodiments, two width-adjusting driving members 212 can also be used to drive the first driving lead screw 211 and the second driving lead screw 321 respectively.

[0045] See Figure 4 and Figure 5 As shown, in a specific embodiment, the pushing assembly 31 includes a mounting seat 311, a push rod 312, and a pushing driving member 313. The mounting seat 311 is movably mounted on the mounting frame 1, and the mounting seat 311 is drivingly connected to the second width-adjusting assembly 32. The push rod 312 is movably mounted on the mounting seat 311. The pushing driving member 313 is mounted on the side of the mounting seat 311 away from the push rod 312, and the pushing driving member 313 is drivingly connected to the push rod 312.

[0046] Specifically, the lower end of the mounting seat 311 is drivingly connected to the second driving lead screw 321 through a screw hole, so that the mounting seat 311 drives the push rod 312 to move along the length direction of the second driving lead screw 321. The push rod 312 is disposed above the mounting seat 311, and the pushing driving member 313 is disposed below the mounting seat 311 to prevent the pushing driving member 313 from obstructing the material pushing.

[0047] Preferably, a buffer pad 3121 is provided at the end of the push rod 312 for abutting against the material to reduce the impact force generated between the push rod 312 and the material when the push rod 312 contacts the material, thereby protecting the material from damage or scratches. At the same time, it can reduce noise and reduce the wear of the push rod 312.

[0048] In a specific embodiment, the push rod 312 is arranged parallel to the first conveying component 22, and a plurality of saw teeth 3122 are provided on one side of the push rod 312 close to the push driving member 313. The plurality of saw teeth 3122 are evenly arranged along the length direction of the push rod 312, and the push driving member 313 is meshed with the saw teeth 3122 through a rotating gear 314.

[0049] Specifically, the push driving member 313 is provided with an output shaft (not shown in the figure), and the rotating gear 314 is transmission-connected to the output shaft of the push driving member 313. When the push driving member 313 drives the rotating gear 314 to rotate through the output shaft, the rotating gear 314 drives the sawtooth 3122 to move, so that the push rod 312 moves along the length direction of the push rod 312, thereby pushing the material. The above structure is simple and stable, and has high transmission efficiency. It can be understood that the above push driving member 313 can be a driving member such as a motor or a rotary cylinder.

[0050] In a specific embodiment, a plurality of guide wheels 3111 are provided on the mounting seat 311 , a guide groove 3123 is provided on the push rod 312 , the guide groove 3123 is arranged along the length direction of the push rod 312 , and the guide wheels 3111 are slidably connected to the guide groove 3123 .

[0051] Specifically, at least two guide grooves 3123 are provided on the push rod 312, and the two guide grooves 3123 are respectively provided on both sides of the push rod 312 close to the first conveying assembly 22 and the second conveying assembly 23. The number of guide wheels 3111 is at least four, and one guide groove 3123 corresponds to two guide wheels 3111 to achieve accurate guiding, and at the same time enable the guide wheels 3111 to stably support the push rod 312.

[0052] In a specific embodiment, the pushing assembly 31 further includes a lifting driving member 315 . The lifting driving member 315 is installed on a side of the mounting seat 311 away from the push rod 312 , and the lifting driving member 315 is transmission-connected to the mounting seat 311 .

[0053] Specifically, the lifting drive member 315 is provided with a telescopic rod 3151, and the telescopic rod 3151 is transmission-connected to the mounting seat 311. When the material has not yet been delivered to the end of the conveying mechanism 2, the telescopic rod 3151 of the lifting drive member 315 is in a retracted state, and the mounting seat 311 and the push rod 312 are located below the material to prevent the movement of the material from being hindered during the process of the conveying mechanism 2 delivering the material to the end; after the material is delivered to the end of the conveying mechanism 2, the telescopic rod 3151 is extended to lift the mounting seat 311 and the push rod 312, and the push drive rod then drives the push rod 312 to move in the direction of the material, so as to push the material to continue to move and gradually leave the conveying mechanism 2.

[0054] In a specific embodiment, the mounting base 311 is provided with an upper mounting layer 3112 and a lower mounting layer 3113. The lifting driving member 315 is mounted on the lower mounting layer 3113, and the telescopic rod 3151 of the lifting driving member 315 is drivingly connected to the upper mounting layer 3112. A lifting bearing seat 3114 is also mounted on the lower mounting layer 3113, and the lifting bearing seat 3114 is also drivingly connected to the upper mounting layer 3112. The push rod 312 and the guide wheel 3111 are mounted above the upper mounting layer 3112, and the pushing driving member 313 is mounted below the upper mounting layer 3112.

[0055] Specifically, the lifting driving member 315 and the lifting bearing seat 3114 are jointly drivingly connected to the upper mounting layer 3112, so that the upper mounting layer 3112 is stably supported and driven to lift, thereby driving the push rod 312 to lift stably.

[0056] Preferably, the lower mounting layer 3113 is provided with an avoidance groove 31131, and the main body of the pushing driving member 313 is located in the avoidance groove 31131. When the upper mounting layer 3112 is driven to lift, the main body of the pushing driving member 313 lifts synchronously in the avoidance groove 31131. By providing the avoidance groove 31131, it is convenient for the installation of the pushing driving member 313, and the structure of the mounting base 311 is compact, reducing the volume and weight of the mounting base 311, thereby saving the occupied space and reducing the materials required for production.

[0057] See Figures 1 to 3 As shown, in a specific embodiment, the mounting frame 1 is further provided with a linear guide rail group 11. The linear guide rail group 11 is perpendicular to the first conveying assembly 22, and the first conveying assembly 22 and the pushing assembly 31 are slidably connected to the linear guide rail group 11.

[0058] Specifically, the linear guide rail group 11 includes a first linear guide rail 111, a second linear guide rail 112, and a third linear guide rail 113 that are parallel to each other. The front end and the end of the first conveying assembly 22 are respectively slidably connected to the first linear guide rail 111 and the second linear guide rail 112, and the lower mounting layer 3113 is slidably connected to the second linear guide rail 112 and the third linear guide rail 113. By providing the above linear guide rail group 11, when adjusting the positions of the first conveying assembly 22 and the pushing assembly 31, the first conveying assembly 22 and the pushing assembly 31 move along the length direction of the linear guide rail group 11 without trajectory deviation, and at the same time provide stable support for the first conveying assembly 22 and the pushing assembly 31.

[0059] Preferably, the first linear guide rail 111, the second linear guide rail 112, and the third linear guide rail 113 are cylindrical guide rails with the same size. The cylindrical guide rails have the advantages of high precision, low friction coefficient, maintaining high precision for a long time, and reducing driving power, etc., thereby effectively improving the energy utilization rate.

[0060] See Figures 1 to 3 and Figure 6 As shown, in a specific embodiment, the conveying mechanism 2 further includes a conveying driving member 24 mounted on the mounting frame 1; the first conveying assembly 22 includes a mounting member 221, a transmission gear set 222, and a conveying chain 223; the mounting member 221 is mounted on the mounting frame 1, the conveying driving member 24 and the transmission gear set 222 are mounted on the mounting member 221, and the transmission gear set 222 is drivingly connected to the conveying driving member 24; the conveying chain 223 is drivingly connected to the transmission gear set 222. The structure of the second conveying assembly 23 is the same as that of the first conveying assembly 22, and both include the above-mentioned mounting member 221, transmission gear set 222, and conveying chain 223. The difference is that the mounting member 221 in the second conveying assembly 23 is fixedly connected to the mounting frame 1, while the mounting member 221 in the first conveying assembly 22 is movably connected to the mounting frame 1.

[0061] Specifically, the front end and the rear end of the mounting member 221 in the first conveying assembly 22 are respectively drivingly connected to the third driving lead screw 214 and the first driving lead screw 211, and the front end and the rear end of the mounting member 221 are respectively slidably connected to the first linear guide rail 111 and the second linear guide rail 112, so as to realize that the position of the first conveying assembly 22 is controlled and adjusted by the first width-adjusting assembly 21.

[0062] Preferably, a plurality of conveying round rods 2231 are provided on one side of the conveying chain 223 close to the pushing assembly 31. The conveying round rods 2231 are used to carry the material and drive the material to move, so as to realize material conveying. Moreover, the friction between the conveying round rods 2231 and the material is small, effectively improving the conveying efficiency. More preferably, a pushing block 2232 is further provided on one side of the conveying chain 223 close to the pushing assembly 31. When conveying the material, the pushing block 2232 abuts against the rear end of the material to prevent the situation that the conveying round rods 2231 are difficult to drive the material to move due to the overweight of the material.

[0063] The above embodiments are the preferred implementation solutions of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the technical solution is within the protection scope of the present invention.
