Description

Technical Field

[0001] The utility model relates to a non-powered roller express conveyor and belongs to the technical field of roller conveyors. Background Art

[0002] Roller conveyors are suitable for conveying various types of boxes, bags, pallets and other piece goods. Bulk materials, small items or irregular items need to be placed on pallets or in turnover boxes for transportation. They can convey single-piece materials with very large weight or withstand large impact loads. The roller lines are easy to connect and filter. Multiple roller lines and other conveyors or special machines can be used to form a complex logistics transportation system to meet various process needs. Accumulation rollers can be used to achieve stacking and conveying of materials. Roller conveyors have a simple structure, high reliability, and easy use and maintenance. Roller conveyors are suitable for conveying items with a flat bottom. They are mainly composed of drive rollers, frames, brackets, drive parts and other parts. They have the characteristics of large conveying capacity, fast speed, light operation, and can realize multi-variety co-linear diversion transportation. There are many types of roller conveyors, including unpowered roller conveyors for express delivery.

[0003] The rollers in the unpowered roller conveyor are mainly connected to the inner side of the conveyor frame by a rotating shaft, and the rotating shaft itself has a certain length, so there is often a certain gap between the roller and the frame. In express delivery, the sizes of express items are often different, and some express items are often smaller in size. As these smaller express items are transported through the rollers, they may slide left and right on the surface of the rollers, causing the express items to fall from the gap between the rollers and the transport frame, making it impossible to transport the express items normally, affecting the use of the operators.

[0004] To this end, a non-powered roller express conveyor is proposed. Utility Model Content

[0005] In view of this, the utility model provides a non-powered roller express conveyor to solve or alleviate the technical problems existing in the prior art and at least provide a beneficial choice.

[0006] The technical solution of the utility model is implemented as follows: a non-powered roller express conveyor comprises a frame, the inner side of the frame is movably connected with a roller body, the left and right sides of the bottom of the frame are fixedly installed with mounting plates, and the bottom of the frame is fixedly installed with support rods;

[0008] Further preferably, limit grooves are provided on both left and right sides of the frame surface, limit blocks are fixedly installed on the bottoms of the two tooth plates, and the two limit blocks are slidably connected in the inner cavities of the two limit grooves.

[0009] Further preferably, movable grooves are provided on both left and right sides of the frame surface, and the two movable blocks penetrate the inner cavities of the two movable grooves and extend to the bottom of the frame.

[0010] Further preferably, sliding bars are fixedly installed on both the front and rear sides of the outer side of the frame, and the inner surfaces of the left and right sides of the two protective baffles are slidably connected to the surfaces of the four sliding bars.

[0011] Further preferably, a moving mechanism is provided on the right side of the outer side of the mounting plate, and the moving mechanism includes a second servo motor, the second servo motor is fixedly mounted on the right side of the outer side of the mounting plate, the output end of the second servo motor is fixedly connected with a bidirectional screw, the left and right sides of the surface of the bidirectional screw are threadedly connected with screw blocks, the bottoms of the two screw blocks are movably connected with mounting rods, the bottoms of the two mounting rods are movably connected with a moving plate, and the bottoms of the moving plates are movably connected with universal wheels.

[0012] Further preferably, movable grooves are provided around the top of the movable plate, and the four support rods are slidably connected to the inner cavities of the four movable grooves.

[0013] Further preferably, limiting rods are fixedly installed on both the front and rear sides of the inner sides of the two mounting plates, and the inner surfaces of the two screw blocks are slidably connected to the surfaces of the two limiting rods.

[0014] Further preferably, the bottoms of the four support rods are each provided with anchor bolts, and the anchor bolts are threadedly connected to the ground.

[0015] The embodiment of the utility model has the following advantages due to the adoption of the above technical solution:

[0016] 1. The utility model sets a protective mechanism. First, the output of the first servo motor is used to rotate the gear. At this time, the toothed plate is meshed with the gear, and moves inward along the surface of the sliding rod as the gear rotates. At this time, the toothed plate drives the moving block to move inward synchronously, and makes the connecting rod push the protective baffle to move inward, so that the protective baffle is at the top of the drum body. By moving the protective baffle inward, the movable space on the top of the drum body is contracted, thereby reducing the problem of express items sliding easily in the front and rear directions when being transported through the drum body, and then avoiding the express items from falling from the gap between the drum body and the frame due to sliding during transportation, thereby protecting the express items.

[0017] Second, the utility model can limit the moving direction of the tooth plate by setting the limit block and the limit groove, so as to avoid the tooth plate from deviating when moving, thereby affecting the adjustment work of the front and rear spacing of the protective baffle and affecting the protective effect of the express delivery. By setting the moving groove, the movement of the moving block can be limited to avoid the direction of the moving block from deviating when moving, thereby affecting the protective work of the express delivery. By setting the sliding rod, the moving direction of the protective baffle can be limited to avoid the change of its direction during the movement, resulting in horizontal movement to the top of the drum body, thereby affecting the protective effect of the express delivery. By setting the moving mechanism, through the output of the second servo motor, the bidirectional screw drives the screw block to move outward, and causes the mounting rod to flip. Through the flipping of the mounting rod, the moving plate drives the universal wheel to move downward. The support rod is disengaged from the ground, and then the position of the entire equipment can be adjusted according to the use requirements, which is convenient for the operator to use and improves the convenience of the overall movement of the equipment. By setting the movable groove, the movement of the movable plate can be limited through cooperation with the support rod, so that the direction of the movable plate will not shift when moving downward, thereby causing the problem of all the universal wheels contacting the ground. By setting the limit rod, the moving direction of the screw block can be limited to prevent the screw block from rotating synchronously with the bidirectional screw when it rotates, thereby affecting the lifting and lowering of the universal wheel. By setting the support rod, since the bottom of the support rod is provided with anchor bolts, the overall stability of the equipment can be improved when the equipment is installed, and the overall shaking of the equipment due to external collision can be avoided, thereby causing the express to fall from the top of the drum body.

DETAILED DESCRIPTION

[0026] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0027] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0028] Example 1

[0029] like Figure 1-5 As shown, the embodiment of the utility model provides a non-powered roller express conveyor, including a frame 1, the inner side of the frame 1 is movably connected with a roller body 4, the left and right sides of the bottom of the frame 1 are fixedly installed with a mounting plate 6, and the bottom of the frame 1 is fixedly installed with a support rod 5;

[0030] A protective mechanism 2 is fixedly installed at the bottom of the frame 1, and the protective mechanism 2 includes a first servo motor 201, which is fixedly installed at the bottom of the frame 1. The output end of the first servo motor 201 is fixedly connected to a gear 202. Sliding rods 203 are fixedly installed on the left and right sides of the inner side of the frame 1. The surfaces of the two sliding rods 203 are slidably connected with tooth plates 204. The inner sides of the two tooth plates 204 are meshed with the outer sides of the sliding rods 203. Moving blocks 205 are fixedly installed at the bottom of the two tooth plates 204. Connecting rods 206 are fixedly installed on the inner sides of the two moving blocks 205. Protective baffles 207 are fixedly installed on the inner sides of the two connecting rods 206.

[0031] By setting up the protection mechanism 2, firstly, the output of the first servo motor 201 is used to make the gear 202 rotate. At this time, the tooth plate 204 is meshed with the gear 202, and moves inward along the surface of the sliding rod 203 as the gear 202 rotates. At this time, the tooth plate 204 drives the moving block 205 to move inward synchronously, and makes the connecting rod 206 push the protective baffle 207 to move inward, so that the protective baffle 207 is at the top of the drum body 4. By moving the protective baffle 207 inward, the movable space at the top of the drum body 4 is shrunk, thereby reducing the problem of easy sliding of express items in the front and rear directions when being transported through the drum body 4, and then avoiding the express items from falling from the gap between the drum body 4 and the frame 1 due to sliding during transportation, thereby protecting the express items.

[0032] Example 2

[0033] In one embodiment, limit grooves 208 are provided on the left and right sides of the surface of the frame 1, limit blocks 209 are fixedly installed at the bottoms of the two tooth plates 204, and the two limit blocks 209 are slidably connected in the inner cavities of the two limit grooves 208. Moving grooves 210 are provided on the left and right sides of the surface of the frame 1, and the two moving blocks 205 pass through the inner cavities of the two moving grooves 210 and extend to the bottom of the frame 1. Slide bars 211 are fixedly installed on the front and back sides of the outer side of the frame 1, and the inner surfaces of the left and right sides of the two protective baffles 207 are slidably connected to the surfaces of the four slide bars 211. A moving mechanism 3 is provided on the right side of the outer side of the mounting plate 6, and the moving mechanism 3 includes a second servo motor 301, and the second servo motor 301 is fixedly installed on the right side of the outer side of the mounting plate 6. The output end of the servo motor 301 is fixedly connected with a bidirectional screw rod 302, and the left and right sides of the surface of the bidirectional screw rod 302 are threadedly connected with screw blocks 303, the bottoms of the two screw blocks 303 are movably connected with mounting rods 304, the bottoms of the two mounting rods 304 are movably connected with movable plates 305, the bottoms of the movable plates 305 are movably connected with universal wheels 306, movable grooves 307 are provided around the top of the movable plate 305, and four support rods 5 are slidably connected to the inner cavities of the four movable grooves 307, and limiting rods 308 are fixedly installed on the front and rear sides of the inner sides of the two mounting plates 6, the inner surfaces of the two screw blocks 303 are slidably connected to the surfaces of the two limiting rods 308, and the bottoms of the four support rods 5 are provided with anchor bolts, and the anchor bolts are threadedly connected to the ground.

[0034] By setting the limit block 209 and the limit groove 208, the moving direction of the tooth plate 204 can be limited to avoid the tooth plate 204 from deviating when moving, thereby affecting the adjustment of the front and rear spacing of the protective baffle 207 and affecting the protective effect on the express delivery. By setting the moving groove 210, the movement of the moving block 205 can be limited to avoid the moving block 205 from deviating in direction when moving, thereby affecting the protective work of the express delivery. By setting the sliding rod 211, the moving direction of the protective baffle 207 can be limited to avoid its direction changing during the movement, resulting in horizontal movement to the top of the drum body 4, thereby affecting the protective effect on the express delivery. By setting the moving mechanism 3, through the output of the second servo motor 301, the bidirectional screw 302 drives the screw block 303 to move outward, and causes the mounting rod 304 to flip. Through the flipping of the mounting rod 304, the moving plate 305 drives the universal wheel downward. The movable groove 307 can be provided to limit the movement of the movable plate 305 through cooperation with the support rod 5, so that the direction of the movable plate 305 will not be offset when the movable plate 305 moves downward, thereby causing the problem that the universal wheel 306 is all in contact with the ground. The limiting rod 308 can be provided to limit the movement direction of the screw block 303, so that when the bidirectional screw 302 rotates, the screw block 303 does not rotate synchronously with it, thereby affecting the lifting and lowering of the universal wheel 306. The support rod 5 is provided, and since the bottom thereof is provided with anchor bolts, the stability of the entire equipment can be improved when the equipment is installed as a whole, so as to avoid the shaking of the equipment as a whole due to external collision, thereby causing the express to fall from the top of the drum body 4.

[0035] When the utility model is working: the output of the first servo motor 201 causes the gear 202 to rotate. At this time, driven by the gear 202, the toothed plate 204 moves inward along the surface of the sliding rod 203, and the moving block 205 moves inward synchronously due to the movement of the toothed plate 204, and pulls the connecting rod 206 inward to move. At this time, as the connecting rod 206 moves, the protective baffle 207 is pushed inward by the connecting rod 206, so that the connecting rod 206 is at the top of the drum body 4, thereby completing the protection effect for express items of different sizes. When it is necessary to adjust the position of the entire equipment, the limit of the anchor bolt at the bottom of the support rod 5 is released, and then the bidirectional screw 302 is driven to rotate by the output end of the second servo motor 301. At this time, the screw block 303 moves along the surface of the bidirectional screw 302. The device moves outwards. Due to the movement of the screw block 303, the mounting rod 304 flips inwards and pushes the moving plate 305 to move downwards. At this time, the universal wheel 306 moves downwards synchronously with the moving plate 305. As the universal wheel 306 continues to move downwards, the entire device is lifted up and the support rod 5 leaves the ground. After the position of the device is adjusted according to the use requirements, the output end of the second servo motor 301 drives the bidirectional screw 302 to rotate in the opposite direction. At this time, the screw block 303 moves inwards, and the mounting rod 304 flips outwards due to the movement of the screw block 303, and pulls the moving plate 305 and the universal wheel 306 to move upwards. At this time, the support rod 5 contacts the ground again, and then the entire device is stabilized again by the anchor bolts arranged at the bottom of the support rod 5 to complete the movement of the entire device.

[0036] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
