Description

Technical Field

[0001] This utility model belongs to the field of conveyors, specifically a conveyor tension adjustment structure. Background Technology

[0002] In industrial equipment, multiple conveyor belts are used to separate and transport products or components; some conveying structures require multiple narrow belt conveyors to be arranged side by side, such as sorting and transporting devices. Narrow belt conveyors need to be equipped with tension adjustment mechanisms to readjust the tension after the conveyor belt slackens; the tension adjustment mechanism of a conventional narrow belt conveyor is usually located at the end of the conveyor.

[0003] Belt conveyors primarily utilize belts for power transmission. The belt transmits power through friction, therefore, the belt tension must be adjusted to achieve the appropriate friction. Adjusting the belt tension regulates the friction between the belt and the pulleys; the tension is controlled by a tensioning pulley. An overly tight belt will cause severe wear, while an overly loose belt will slip, leading to severe wear or even burnout. However, existing conveyors do not readily allow for belt tension adjustment. To avoid affecting the conveyor's position, most conveyor structures have a tension adjustment mechanism at the bottom. This results in awkward angles during conventional tension adjustments and makes it difficult to monitor the belt tension after adjustment. Consequently, adjusting the tension after the belt becomes loose is extremely cumbersome.

[0004] In summary, this utility model provides a conveyor tension adjustment structure to solve the above problems. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a conveyor tension adjustment structure, which solves the problem that the process of adjusting the tension of the conveyor structure after the conveyor belt becomes loose is very cumbersome in the prior art.

[0006] A conveyor tensioning adjustment structure includes a conveyor, comprising a conveyor belt and a frame. The frame is disposed on both sides of the conveyor belt, and tension rollers and conveying rollers are respectively disposed at both ends of the conveyor belt. The tension rollers are mounted on the frame via rotating shafts on both sides. Tensioning slots are respectively opened on the frame, and the rotating shafts movably pass through the tensioning slots and are rotatably connected to rotating shaft seats. Racks are respectively installed on the side of the frame near the conveyor belt, and shifting gears are movably disposed on the racks. Pull shafts are installed on the side of the shifting gears near the frame, and pull shaft sleeves are movably sleeved on the surface of the pull shafts. The pull shaft sleeves slide along the axial direction of the pull shafts, and a locking disc is fixedly connected to one end of the pull shaft sleeves. Multiple locking blocks are installed on the locking disc. Two locking strips are installed on the side of the frame away from the conveyor belt. The pull shafts and rotating shaft seats are connected by push rods.

[0007] Furthermore, the tensioning groove is arranged along the length of the conveyor belt, the locking strips are respectively arranged parallel to the upper and lower ends of the tensioning groove, and the locking grooves are equidistantly arranged along the length of the locking strips.

[0008] Furthermore, the pull shaft sleeve is disposed on the side of the frame away from the conveyor belt, the locking disc is movably disposed on one side of the frame and is disposed close to the locking strip, the locking blocks are arranged in an array along the circumferential direction of the locking disc, and the size of the locking blocks is matched with that of the locking groove.

[0009] Furthermore, one end of the push rod is rotatably sleeved on the surface of the pull shaft, and the other end of the push rod is fixedly connected to one side of the rotating shaft seat.

[0010] Furthermore, the surface of the pull shaft is provided with a spline groove, the inner wall of the pull shaft sleeve is slidably connected in the spline groove by a spline block, and one end of the pull shaft is connected to the inner wall of the top end of the pull shaft sleeve by a return spring.

[0024] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0025] like Figures 1-5As shown, this utility model provides a conveyor tension adjustment structure, including a conveyor 1, which includes a conveyor belt and a frame 2. The frame 2 is arranged on both sides of the conveyor belt. Tensioning rollers 5 and conveying rollers are respectively arranged at both ends of the conveyor belt. The two sides of the tensioning rollers 5 are arranged on the frame 2 through rotating shafts 4. Tensioning slots are respectively opened on the frame 2. The rotating shafts 4 movably pass through the tensioning slots and are rotatably connected to the rotating shaft seats. Racks 7 are respectively installed on the side of the frame 2 near the conveyor belt. Shifting gears 11 are movably arranged on the racks 7. Pull shafts 15 are installed on the side of the shifting gears 11 near the frame 2. Pull shaft sleeves 3 are movably sleeved on the surface of the pull shafts 15. The pull shaft sleeves 3 slide along the axial direction of the pull shafts 15. A locking disc 6 is fixedly connected to one end of the pull shaft sleeve 3. Multiple locking blocks 13 are installed on the locking disc 6. Two locking strips 8 are installed on the side of the frame 2 away from the conveyor belt. The pull shafts 15 and the rotating shaft seats are connected by push rods 10.

[0026] In one embodiment of this utility model, the tensioning groove is arranged along the length of the conveyor belt, the locking strips 8 are respectively arranged parallel to the upper and lower ends of the tensioning groove, and the locking grooves are arranged at equal intervals along the length of the locking strips 8.

[0027] In one embodiment of this utility model, the pull shaft sleeve 3 is disposed on the side of the frame 2 away from the conveyor belt, the locking disc 6 is movably disposed on one side of the frame 2 and is disposed close to the locking strip 8, and the locking blocks 13 are arranged in an array along the circumferential direction of the locking disc 6, and the size of the locking blocks 13 is matched with that of the locking groove.

[0028] In one embodiment of this utility model, one end of the push rod 10 is rotatably sleeved on the surface of the pull shaft 15, and the other end of the push rod 10 is fixedly connected to one side of the rotating shaft seat.

[0029] As one embodiment of this utility model, a spline groove 14 is provided on the surface of the pull shaft, and the inner wall of the pull shaft sleeve 3 is slidably connected in the spline groove 14 through a spline block. One end of the pull shaft is connected to the top inner wall of the pull shaft sleeve 3 through a return spring 12.

[0030] In one embodiment of this utility model, the shifting gears 11 on both sides of the conveyor 1 are fixedly connected by a linkage shaft 9, which is located on one side of the tension roller 5.

[0031] In one embodiment of this utility model, the rotating shaft seat is in movable contact with the surface of the frame 2, and the rotating shaft seat is disposed between two locking bars 8.

[0032] Specific working principle:

[0033] Tensioning roller 5 is installed at the end of conveyor 1. The tension of the conveyor belt is adjusted by moving the position of tensioning roller 5 on frame 2. This makes the belt more stable with the entire conveyor 1. When adjusting the tension, the tension is adjusted precisely according to the tightness of the conveyor belt. The position of tensioning roller 5 is adjusted to tighten the conveyor belt.

[0034] By setting up the pull shaft sleeve 3 and the pull shaft 15, pulling the pull shaft sleeve 3 outward causes it to slide on the surface of the pull shaft 15, thereby squeezing the return spring 12 and causing the locking disc 6 to move away from the surface of the locking bar 8. The pull shaft sleeve 3 can adjust the rotation of the pull shaft 15 from the outside. When the pull shaft sleeve 3 is rotated, it drives the shift gear 11 to rotate. By setting up the shift gear 11, the shift gear 11 rotates on the surface of the rack 7, and then the shift gear 11 moves horizontally on the rack 7. By changing the rotation direction of the shift gear 11, the forward and backward directions can be adjusted. When the shift gear 11 moves horizontally, the pull shaft sleeve 3 simultaneously pushes the tension roller 5 to move left and right through the push rod 11, thereby achieving the purpose of adjusting the position of the tension roller 5.

[0035] By setting the locking disc 6, the rotation of the entire shift gear 11 is positioned to prevent the shift gear 11 from rotating during use, i.e., when the conveyor belt is in normal use, thus affecting the tension of the conveyor belt. By setting the locking bar 8 and the locking disc 6, in the natural state, the return spring 12 elastically contracts the pull shaft sleeve 3 and the pull shaft 15, and the locking disc 6 approaches the locking bar 8. The locking block 13 on the locking disc 6 is inserted into the locking groove in the locking bar 8. When fixing the position, it automatically matches and locks according to the different locking grooves on the locking bar 8, thereby achieving the purpose of restricting the rotation of the shift gear 11.

[0036] The embodiments of this utility model are given for the purpose of illustration and description. Although embodiments of this utility model have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this utility model. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this utility model.
