Description

Technical Field

[0001] This utility model relates to the field of plate chain conveyor technology, specifically to a tensioning mechanism for an anti-jamming plate chain conveyor. Background Technology

[0002] The tensioning mechanism of a plate chain conveyor is an important mechanism to ensure the appropriate tension of the plate chain during operation and to prevent slippage and slack. Its core function is to adjust and maintain the tension of the plate chain through mechanical devices, so as to maintain the correct friction conditions and transmission efficiency between the transmission rollers, chain and load.

[0003] In the existing technology, when it is necessary to adjust the tension of plate chains of different lengths, the overall adjustment of plate chain conveyors is relatively cumbersome and troublesome for operators.

[0004] To overcome the above shortcomings, a prior art Chinese patent (publication number CN220949794U) discloses a feeding bin and its tensioning mechanism, comprising: a pallet slidably disposed on a housing; a drive shaft rotatably disposed on the pallet, the drive shaft being used to set a sprocket and chain transmission mechanism; and an elastic tensioning component connected to the pallet, the elastic tensioning component driving the pallet to move away from the elastic tensioning component, thereby achieving tensioning of the drive shaft and the sprocket and chain transmission mechanism. The feeding bin includes a housing, on which the above-mentioned tensioning mechanism is disposed, solving the technical problem that the manual tensioning mechanism of the existing plate chain weighing bin chain is inconvenient to adjust, easily causing tensioning mechanism failure and damage to transmission components.

[0005] While existing technologies can overcome the shortcomings mentioned above, other problems still exist during their operation. For example, when the tensioning mechanism adjusts the tension of the plate chain conveyor, jamming is prone to occur, which can affect the smoothness of the tensioning mechanism's operation. Utility Model Content

[0006] The purpose of this utility model is to provide a tensioning mechanism for a plate chain conveyor that prevents jamming, in order to solve the problem mentioned in the background art that jamming is easy to occur when the tensioning mechanism adjusts the tension of the plate chain conveyor, and that jamming can easily affect the smooth operation of the tensioning mechanism.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a tensioning mechanism for a plate chain conveyor that prevents jamming, comprising a body and a panel disposed at the front end of the body. An abutment block is fixedly installed on the inner wall of the body, and a movable sleeve block is disposed between the upper and lower abutment blocks. The movable sleeve block has a hole in the center for fitting a plate chain roller. A side plate is bolted to the side of the body, and a smooth adjustment structure is disposed between the side plate and the movable sleeve block. The smooth adjustment mechanism reduces the probability of jamming during tensioning mechanism adjustment. A locking protection mechanism is disposed between the body and the panel, and the locking protection mechanism facilitates maintenance and replacement of internal components.

[0008] Furthermore, the smooth adjustment mechanism is provided with a threaded rod, and the middle end of the threaded rod is installed inside the side plate through a threaded sleeve, and the end of the threaded sleeve is fixedly installed on the inner wall of the side plate. The right side of the threaded rod is rotatably connected to the end of the movable sleeve block.

[0009] Furthermore, a positioning nut is threadedly installed at the middle end of the threaded rod, and the positioning nut is located on the outside of the side plate. An adjusting nut is fixedly installed at the middle end of the threaded rod, and the adjusting nut is welded to the threaded rod. A limit nut is threadedly installed at the end of the threaded rod.

[0010] Furthermore, a pressure spring is fitted onto the surface of the threaded rod, and the left and right ends of the pressure spring are located between the side plate and the adjusting nut, and the pressure spring and the side disc of the adjusting nut are only in contact.

[0011] Furthermore, the upper and lower ends of the movable sleeve are grooved, and the upper and lower ends of the movable sleeve are fitted onto the surface of the abutment block.

[0012] Furthermore, the locking protection mechanism is provided with a fixing block, and the bottom end of the fixing block is fixedly installed on the surface of the machine body. An adjustment handle is installed through the inside of the fixing block, and a locking block is fixedly installed at the end of the adjustment handle. The locking block is inclined, and a locking spring is provided between the locking block and the fixing block.

[0013] Furthermore, an mounting block is fixedly installed on the upper end of the panel, and a slot is formed on the surface of the mounting block, with the slot corresponding to the locking block.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. First, use a wrench to turn the positioning nut to move it to the side to loosen the limit; then, use a wrench to turn the adjusting nut. As the threaded rod moves, the movable sleeve will move accordingly; in conjunction with the pressure spring sleeved on the surface of the threaded rod, it can apply reverse pressure during the tension adjustment process, which not only improves the smoothness of the adjustment, but also provides support to prevent damage to the device when the tension is too high, further enhancing the stability of the structure and ensuring the smooth progress of the tension adjustment process.

[0016] 2. When the mounting block of the locking protection mechanism is aligned and embedded inside the fixing block, the locking block will snap into the slot, thereby locking the mounting block and the panel together. Conversely, by pulling the adjustment handle, the locking block can be disengaged from the slot, making it easier for staff to disassemble and replace internal parts, reducing maintenance costs, and enabling simpler operation when adjusting tension.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1: As Figures 1-4 The technical solution shown is a tensioning mechanism for an anti-jamming plate chain conveyor. To solve the problem of jamming, it discloses: a body 1 and a panel 2 at the front end of the body 1; an abutment block 4 is fixedly installed on the inner wall of the body 1, and a movable sleeve block 5 is provided between the upper and lower abutment blocks 4; the movable sleeve block 5 has a hole in its center for fitting the plate chain roller; a side plate 3 is bolted to the side of the body 1, and a smooth adjustment mechanism is provided between the side plate 3 and the movable sleeve block 5; the smooth adjustment mechanism reduces the probability of jamming during tensioning mechanism adjustment; the smooth adjustment mechanism is provided with a threaded rod 6, and the middle end of the threaded rod 6 is installed inside the side plate 3 through a threaded sleeve 7; the threaded sleeve 7... The end of the threaded rod 6 is fixedly installed on the inner wall of the side plate 3. The right side of the threaded rod 6 is rotatably connected to the end of the movable sleeve block 5. The middle end of the threaded rod 6 is threaded with a positioning nut 8, which is located on the outside of the side plate 3. The middle end of the threaded rod 6 is fixedly installed with an adjusting nut 9, which is welded to the threaded rod 6. The end of the threaded rod 6 is threaded with a limit nut 10. The surface of the threaded rod 6 is fitted with a pressure spring 11, and the left and right ends of the pressure spring 11 are located between the side plate 3 and the adjusting nut 9. The pressure spring 11 and the side disc of the adjusting nut 9 are only in contact. The upper and lower ends of the movable sleeve block 5 are grooved, and the upper and lower ends of the movable sleeve block 5 are fitted on the surface of the abutment block 4.

[0027] In the tensioning mechanism of the plate chain conveyor, the rear end of the machine body 1 is welded to the plate chain of the plate chain conveyor, and the plate chain roller is sleeved inside the movable sleeve block 5. The positioning nut 8 is pre-rotated by a wrench to move the positioning nut 8 to the side to loosen the limit. Then, the adjusting nut 9 is turned by a wrench, and the adjusting nut 9 drives the threaded rod 6 to rotate. When the threaded rod 6 rotates, it can move a distance along the threaded sleeve 7 on the inner wall of the side plate 3. Limiting nuts 10 are set at both ends of the threaded rod 6 to limit it. As the threaded rod 6 moves, the movable sleeve block 5 moves. Under the limit of the upper and lower abutment blocks 4, the movable sleeve block 5 slides along its surface to adjust the distance. With the help of the pressure spring 11 sleeved on the surface of the threaded rod 6, it can apply pressure in the opposite direction when adjusting the tension. While improving the smoothness of adjustment, it also plays a supporting role, preventing the device from breaking when the tension is too high, further improving stability and ensuring smooth tension adjustment.

[0028] Example 2: Figures 1-7 The technical solution shown, based on Embodiment 1, discloses the following to address the problem of inconvenient disassembly and maintenance: a locking protection mechanism is provided between the body 1 and the panel 2, and the locking protection mechanism facilitates the maintenance and replacement of internal components. The locking protection mechanism is provided with a fixing block 14, and the bottom end of the fixing block 14 is fixedly installed on the surface of the body 1. An adjustment handle 15 is installed through the inside of the fixing block 14, and a locking block 16 is fixedly installed at the end of the adjustment handle 15. The locking block 16 is inclined, and a locking spring 17 is provided between the locking block 16 and the fixing block 14. An installation block 12 is fixedly installed at the upper end of the panel 2, and a slot 13 is opened on the surface of the installation block 12, and the slot 13 corresponds to the locking block 16.

[0029] A panel 2 is provided at the front end of the body 1. The panel 2 is engaged with the upper and lower ends of the body 1 by a locking protection mechanism. When the mounting block 12 of the locking protection mechanism is aligned with the inside of the fixing block 14 and embedded, the mounting block 12 first squeezes the locking block 16. Due to the inclined shape of the locking block 16, the locking block 16 is pushed upward until the slot 13 on the surface of the mounting block 12 corresponds to the locking block 16. Under the action of the locking spring 17, the locking block 16 is engaged in the slot 13, locking the mounting block 12 and the panel 2. Conversely, pulling the adjustment handle 15 can disengage the locking block 16 from the slot 13. This makes it easier for staff to disassemble and replace internal parts, reduces maintenance costs, and makes it easier to adjust the tension.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
