Abstract
Description
Technical Field
[0001] This utility model relates to the field of edgeless conveyor technology, and in particular to an edgeless electric roller conveyor. Background Technology
[0002] A borderless conveyor is a conveying device without baffles or borders at its edges. Currently, Chinese utility model patent CN210456192U discloses a borderless conveyor belt. The conveyor belt has main crossbeams on both sides, and the main crossbeams are welded to a support frame via side plates. Anchor brackets are provided below the support frame. Passive rollers and driving rollers are respectively provided at both ends of the conveyor belt, and several support plates are evenly distributed between the passive rollers and the driving rollers. This borderless conveyor belt has a simple structure. The passive rollers have belt tensioning mechanisms on both sides, which can quickly adjust the tension of the conveyor belt. In addition, the upper and lower surfaces of the conveyor belt wrap around the main crossbeams, and the borderless design prevents the transported materials from scratching the main crossbeams on both sides.
[0003] The aforementioned conveyor belt addresses some shortcomings of existing technologies, but it still has some deficiencies in practical use. For example, it lacks an anti-deviation structure, and during operation, the conveyor belt may deviate, potentially causing materials to fall off. If materials fall off, it will not only disrupt the production process and cause production stoppages, but in severe cases, it may even damage the conveying equipment, increasing maintenance costs and downtime, thus adversely affecting overall production efficiency and economic benefits.
[0004] Therefore, a borderless electric roller conveyor is proposed. Utility Model Content

Detailed Implementation
[0025] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.
[0026] Please refer to Figures 1 to 6 As shown, this embodiment provides a borderless electric roller conveyor, including a conveyor belt 1 and guide rails 2. The two guide rails 2 form a support frame. An electric roller 3 is rotatably mounted on one end of the support frame, and a driven roller 4 is rotatably mounted on the other end. The electric roller 3 and the driven roller 4 are connected by transmission through the conveyor belt 1. The support frame is located inside the conveyor belt 1. The support frame is provided with anti-deviation mechanisms 5 at both ends to prevent the conveyor belt 1 from deviating. The anti-deviation mechanism 5 includes a lead screw 504 rotatably mounted between the two guide rails 2. The two ends of the lead screw 504 have opposite spiral directions and are threadedly rotatably connected to a connecting block 503. The upper end of the connecting block 503 is fixedly connected to a C-shaped seat 501. A limiting roller 502 is rotatably mounted inside the C-shaped seat 501. An annular limiting belt 101 is formed inside the conveyor belt 1, and the limiting roller 502 rolls in contact with the annular limiting belt 101.
[0027] When the lead screw 504 rotates, the opposite directions of its two helical ends cause the connecting blocks 503 at both ends to move in opposite directions along the lead screw 504. The movement of the connecting blocks 503 in turn causes the C-shaped seat 501 and the limiting roller 502 to move. When the conveyor belt 1 tends to deviate, the annular limiting belt 101 will contact the limiting roller 502. The position restriction of the limiting roller 502 constrains the conveyor belt 1 back to the normal operating track, playing a role in preventing deviation. When it is necessary to disassemble the conveyor belt 1, by rotating the lead screw 504, the lead screw 504 is driven to rotate, causing the two connecting blocks 503 to move in opposite directions, thereby releasing the limiting roller 502 from restricting the annular limiting belt 101, so as to facilitate the disassembly and assembly of the conveyor belt 1.
[0028] The anti-deviation mechanism 5 effectively prevents the conveyor belt 1 from running off-track, extends the service life of the conveyor belt 1, avoids material falling, ensures the continuity of the production process, and improves production efficiency.
[0029] In this embodiment, the anti-deviation mechanism 5 also includes a guide rod 505, and a connecting block 503 is slidably sleeved on the guide rod 505. The guide rod 505 is fixedly installed between the two guide rails 2.
[0030] The guide rod 505 provides guidance for the movement of the connecting block 503, so that the connecting block 503 can only move along the axial direction of the guide rod 505 under the rotation of the lead screw 504, thus ensuring the stability and accuracy of the movement of the connecting block 503 and the limiting roller 502.
[0031] In this embodiment, one end of the lead screw 504 rotates through one of the guide rails 2 and is fixedly connected to a handle 506. The operator rotates the handle 506 to drive the lead screw 504 to rotate, thereby adjusting the position of the limit roller 502.
[0032] In this embodiment, a spring 509 is fitted onto one end of the lead screw 504 near the handle 506. One end of the spring 509 is fixed to one side of the guide rail 2. A second friction plate 508 is fixedly connected to the side of the handle 506 near the spring 509, and a first friction plate 507 is fixedly connected to the end of the spring 509 near the handle 506. The first friction plate 507 and the second friction plate 508 are in frictional contact. When the operator rotates the handle 506 to adjust the position of the lead screw 504, the elastic force of the spring 509 keeps the first friction plate 507 and the second friction plate 508 in frictional contact, generating frictional force to prevent the lead screw 504 from rotating on its own due to external vibrations or other factors, thereby fixing the position of the limiting roller 502. In this embodiment, a support plate 6 is detachably installed between the two guide rails 2.
[0033] Working principle: Pallet 6 can be installed or removed according to actual production needs. During installation, pallet 6 provides additional support for the materials on the conveyor belt, preventing the materials from deforming or falling due to their own weight or fluctuations in the operation of the conveyor belt.
[0034] The guide rail 2 has a fixed connection to a limiting support seat 201 on its inner side, and the bottom of the tray 6 has a slot 601. After the tray 6 is placed between the two guide rails 2, the limiting support seat 201 can be inserted into the slot 601 to limit and support the tray 6.
[0035] When the tray 6 is placed between the guide rails 2, the limiting support 201 is inserted into the slot 601 at the bottom of the tray 6, which restricts the position of the tray 6 so that it will not move freely on the guide rails 2, and at the same time provides stable support for the tray 6.
[0036] Beneficial effects: Ensures the stability of pallet 6 after installation, improves the reliability of pallet support for materials, and further ensures the smooth transportation of materials during the production process.
[0037] The foregoing description illustrates and describes several preferred embodiments of the present invention. However, as previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the present invention's conception through the foregoing teachings or related technical or knowledge.
