Description

Technical Field

[0001] This utility model relates to the field of conveyor chain technology, specifically to a material conveying anti-slip chain. Background Technology

[0002] Material conveying chains are used to solve the material handling needs in large-scale production. The main structure of a material conveying chain consists of a chain, sprockets, and a drive device. The chain is generally a metal link or ring and is mostly used for mechanical transmission and traction. In existing chain structures, rotation is achieved by rotating every two adjacent chain plates and fixing them with pins. The distance between the chain plates is the same, and they can mesh with the sprockets to complete the conveying rotation.

[0003] Chinese patent CN212424370U discloses "an agricultural machinery material conveying chain," comprising a first chain plate body and a second chain plate body. The first and second chain plate bodies are composed of a rotating mechanism, a connecting rear plate, and a connecting front plate. The rotating mechanism has a front plate and a rear plate at both ends, and rollers are fixed inside the rear plate. This patent utilizes a rivet that passes through a first and second mounting hole. The rivet's limiting plate limits the connecting front plate. A hole is then drilled in the limiting plate, and a bolt is passed through a fixing hole and fixed with a nut, ensuring the length of the nut and bolt is greater than the length of the first and second mounting holes. A first flange is then welded to the other side of the rivet, limiting the connecting rear plate. This further limits and fixes the rotating mechanism, the connecting front plate, and the connecting rear plate, thereby preventing the rivet from detaching from the chain plate and reducing the risk of breakage and scattering.

[0004] However, in actual use, the existing material conveying chain may become loose after long-term wear between chain 3 and sprocket. When the conveyed material is heavy, the chain may slip when the sprocket rotates, which will affect the conveying efficiency and aggravate the wear of the chain and sprocket, thus affecting the service life of the chain and sprocket. Therefore, a material conveying anti-slip chain is proposed to solve the above-mentioned problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a material conveying anti-slip chain, which solves the problem mentioned in the background art that the chain 3 may become loose after long-term wear, leading to chain slippage.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a material conveying anti-slip chain, comprising a mounting base, a driving device disposed within the mounting base, two sprockets connected to the mounting base via a transmission shaft, and a chain meshing on the two sprockets; further comprising a tensioning assembly for tensioning the chain; and a cleaning assembly for continuously cleaning the chain; the tensioning assembly comprises a fixed base, the fixed base being fixedly mounted on the mounting base, a slider slidably mounted on the mounting base, a spring connecting the slider and the fixed base, and a tensioning wheel rotatably mounted on the slider, the tensioning wheel meshing with the chain.

[0007] Preferably, the chain is composed of multiple links, and a rubber pad is provided at the connection point of every two adjacent links.

[0008] Preferably, the cleaning assembly includes a mounting frame, two rotating shafts, and two cleaning rollers. The mounting frame is fixedly connected to a fixed base, both rotating shafts are rotatably mounted on the mounting frame, and the two cleaning rollers are respectively fixedly connected to the outer walls of the two rotating shafts. The chain passes between the two cleaning rollers and contacts the two cleaning rollers.

[0009] Preferably, the cleaning assembly further includes a driven wheel, multiple paddles, an abutment rod, a connecting rod, a lever, and two gears. The driven wheel is fixedly connected to a rotating shaft near the fixed base. The multiple paddles are fixedly connected to the driven wheel in a circumferential array. The abutment rod is slidably connected to the fixed base. The connecting rod is fixedly connected to the abutment rod. The lever is hinged to the end of the connecting rod away from the abutment rod. The two gears are respectively fixedly connected to two rotating shafts.

[0010] Preferably, a spring is provided between the abutment rod and the fixed base, the abutment rod is provided with an arc-shaped end, and the arc-shaped end of the abutment rod contacts the sprocket located above the abutment rod.

[0011] Preferably, a limit rod and a leaf spring are provided between the lever and the connecting rod, and the lever contacts multiple leaf plates in sequence during movement, and the two gears mesh.

[0012] Preferably, the cleaning assembly further includes two connecting frames, two scraper blades, and a collection box. The two connecting frames are fixedly mounted on the mounting frame, and the two scraper blades are respectively fixedly connected to the two connecting frames. The two scraper blades respectively contact the outer walls of the two cleaning rollers. The collection box is mounted on the mounting frame and is located below the two scraper blades.

[0013] As can be seen from the above technical solutions, the anti-slip chain for material conveying provided in the embodiments of this specification has at least the following beneficial effects:

[0014] 1. This utility model, through the setting of the tensioning component, enables the tensioning wheel to continuously tension the chain using the elastic force of the spring, preventing the chain from loosening after long-term use, and thus preventing the chain from slipping due to loosening; through the setting of rubber pads between the chain links, the rubber pads can play a role in buffering and shock absorption, reducing wear between the chain links, thereby reducing chain wear, extending the chain's service life, and reducing the probability of the chain slipping due to wear.

[0015] 2. This utility model, through the design of the cleaning components, enables two cleaning rollers to continuously clean the chain, protecting it and preventing dirt buildup that could accelerate wear and cause slippage. The driven wheel and two gears work together to ensure the cleaning rollers continue rotating while cleaning the chain, increasing the contact area with the chain per unit time and improving cleaning effectiveness. This also prevents excessive dirt buildup on the same area during continuous cleaning, which would negatively impact cleaning efficiency. The two scraper blades effectively remove dirt from the surfaces of the cleaning rollers into the collection box, maintaining the cleanliness of the rollers and ensuring optimal cleaning results.

[0026] 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.

[0027] Example 1

[0028] Please see Figures 1-3 As shown, a material conveying anti-slip chain includes a mounting base 1, within which a drive device is installed. This drive device, being existing technology, uses a drive shaft to rotate sprockets 2. Its specific structure and working principle are not detailed here. Two sprockets 2 are connected to the mounting base 1 via the drive shaft, and a chain 3 is meshed on each sprocket 2. When the drive device in the mounting base 1 is activated, it can drive the two sprockets 2 to rotate via the two drive shafts. The rotation of the two sprockets 2 causes the chain 3 to rotate. The chain conveying anti-slip chain also includes a tensioning assembly 4 for tensioning the chain 3. The tensioning assembly 4 includes a fixed base 41, which is fixedly mounted on the mounting base 1. A slider 42 is slidably mounted on the mounting base 1, and a spring connects the slider 42 to the fixed base 41. A tensioning wheel 43 is rotatably mounted on the slider 42, meshing with the chain 3. When the chain 3 rotates, it drives the tensioning wheel 43 to rotate. The slider 42 utilizes the elasticity between itself and the fixed base 41 to tension the chain 3 using the tensioning wheel 43, preventing the chain 3 from loosening after prolonged use.

[0029] Furthermore, the chain 3 is composed of multiple links, and a rubber pad 31 is provided at the connection between every two adjacent links. The rubber pad 31 can play a role in buffering and absorbing shock, reducing wear between links, thereby reducing wear on the chain 3 and extending the service life of the chain 3.

[0030] In this embodiment, the tensioning component 4 enables the tensioning wheel 43 to continuously tension the chain 3 using the spring force, preventing the chain 3 from loosening after prolonged use and thus preventing slippage due to loosening. The rubber pads 31 between the chain links of the chain 3 act as buffers and absorb shocks, reducing wear between the links, thereby reducing wear on the chain 3, extending its service life, and reducing the probability of slippage due to wear.

[0031] Example 2

[0032] Please see Figure 1 , Figures 4-8 As shown, a cleaning component 5 is provided on the mounting base 1 for continuous cleaning of the chain 3. The cleaning component 5 includes a mounting frame 51, two rotating shafts 52, and two cleaning rollers 53. The mounting frame 51 is fixedly connected to the fixed base 41. The two rotating shafts 52 are rotatably mounted on the mounting frame 51. The two cleaning rollers 53 are respectively fixedly connected to the outer walls of the two rotating shafts 52. The chain 3 passes between the two cleaning rollers 53 and contacts the two cleaning rollers 53. When the chain 3 rotates, the two cleaning rollers 53 can clean the chain 3, maintain the cleanliness of the chain 3, and prevent the chain 3 from accumulating too much dirt on its surface after long-term use. Dust, metal shavings, sand and other particulate dirt, after being embedded in the chain 3 or adhering to the tooth surface of the sprocket 2, will smooth the micro-roughness of the metal surface, making the contact surface smooth, which will weaken the meshing stability between the chain 3 and the sprocket 2, thereby increasing the probability of the chain 3 slipping.

[0033] In addition, the cleaning assembly 5 also includes a driven wheel 54, multiple paddles 55, an abutment rod 56, a connecting rod 57, a lever 58, and two gears 59. The driven wheel 54 is fixedly connected to a rotating shaft 52 near the fixed base 41. The multiple paddles 55 are fixedly connected to the driven wheel 54 in a circumferential array. The abutment rod 56 is slidably connected to the fixed base 41. The connecting rod 57 is fixedly connected to the abutment rod 56. The lever 58 is hinged to the end of the connecting rod 57 away from the abutment rod 56. The two gears 59 are respectively fixedly connected to the two rotating shafts 52. A spring is provided between the abutment rod 56 and the fixed base 41. The abutment rod 56 has an arc-shaped end, which contacts the sprocket 2 located above the abutment rod 56. The abutment rod 56 uses the elastic force of the spring between itself and the fixed base 41 to maintain pressure on the sprocket 2, so that the abutment rod 56 always abuts against the sprocket 2. The sprocket 2 in contact with the abutment rod 56... During rotation, the arc-shaped end drives the contact rod 56 to move up and down reciprocally. A limit rod and a leaf spring are provided between the lever 58 and the connecting rod 57. When the lever 58 moves, it contacts multiple paddles 55 in sequence, and two gears 59 mesh. The lever 58 is limited by the limit rod and can only swing upwards, not downwards. After the lever 58 swings, it is reset by the elastic force of the leaf spring. During the up and down reciprocating movement, the lever 58 can drive the driven wheel 54 to rotate using multiple paddles 55. When the driven wheel 54 rotates, it drives the shaft 52 connected to it to rotate. The shaft 52 drives another shaft 52 to rotate in the opposite direction using the meshing relationship between the two gears 59. When the two shafts 52 rotate, they drive the two cleaning rollers 53 to rotate respectively, so that the two cleaning rollers 53 can continue to rotate during the cleaning of the chain 3, thereby increasing the contact area with the chain 3 per unit time and thus improving the cleaning effect.

[0034] In addition, the cleaning assembly 5 also includes two connecting frames 510, two scrapers 511, and a collection box 512. The two connecting frames 510 are fixedly mounted on the mounting frame 51. The two scrapers 511 are fixedly connected to the two connecting frames 510 respectively. The two scrapers 511 contact the outer walls of the two cleaning rollers 53 respectively. The collection box 512 is mounted on the mounting frame 51 and is located below the two scrapers 511. When the two cleaning rollers 53 rotate, they contact the two scrapers 511 respectively. The two scrapers 511 can scrape the dirt attached to the surface of the two cleaning rollers 53 into the collection box 512. The collection box 512 can be disassembled for regular cleaning. Operators can also clean the two cleaning rollers 53 regularly to maintain their performance.

[0035] In this embodiment, the cleaning component 5 enables the two cleaning rollers 53 to continuously clean the chain 3, protecting the chain 3 and preventing it from becoming dirty and slipping. The driven wheel 54 and the two gears 59 work together to ensure the two cleaning rollers 53 continue to rotate while cleaning the chain 3, increasing the contact area with the chain 3 per unit time and improving the cleaning effect. This also prevents the cleaning rollers 53 from accumulating excessive dirt on the same area during continuous cleaning, which would negatively impact the cleaning effect. The two scraper strips 511 scrape the dirt from the surfaces of the two cleaning rollers 53 into the collection box 512, maintaining the cleanliness of the cleaning rollers 53 and ensuring a good cleaning result.

[0036] When the material conveying anti-slip chain of this utility model is in use, after the drive device in the mounting base 1 is started, it can drive two sprockets 2 to rotate through two transmission shafts. When the two sprockets 2 rotate, they drive the chain 3 to rotate. The rubber pads 31 on the chain 3 can play a role in buffering and shock absorption, reducing the wear between chain links, thereby reducing the wear of the chain 3 and extending the service life of the chain 3. When the chain 3 rotates, it drives the tension wheel 43 to rotate. The slider 42 uses the elasticity between itself and the fixed base 41 to make the tension wheel 43 tension the chain 3, so as to prevent the chain 3 from loosening after long-term use.

[0037] When the chain 3 rotates, the two cleaning rollers 53 clean the chain 3, maintaining its cleanliness and preventing dirt from accumulating on its surface after prolonged use. Dust, metal shavings, sand, and other particulate matter, after embedding in the chain 3 or adhering to the teeth of the sprocket 2, will smooth the micro-roughness of the metal surface, making the contact surface smooth. This weakens the meshing stability between the chain 3 and the sprocket 2, increasing the probability of chain slippage. Therefore, the two cleaning rollers 53, by continuously cleaning the chain 3, can protect it and provide a certain degree of anti-slip effect. The abutment rod 56 utilizes the spring between itself and the fixed seat 41... The force maintains pressure on the sprocket 2, ensuring that the abutment rod 56 always abuts against the sprocket 2. When the sprocket 2 rotates, it drives the abutment rod 56 to move up and down reciprocally. The sprocket 2, through the connecting rod 57, drives the lever 58 to move up and down reciprocally. The lever 58 is limited by the limiting rod, allowing it to swing upwards but not downwards. After swinging, the lever 58 returns to its original position using the spring force of the leaf spring. Therefore, when the lever 58 moves downwards, it slides on the surface of one of the leaf plates 55 and swings upwards. Subsequently, the lever 58 disengages from the leaf plate 55. During this process, the lever 58 does not cause the leaf plate 55 to move. When the lever 58 moves upwards… When the lever 58 cannot swing downwards, it presses against the paddle 55, which in turn drives the driven wheel 54 to rotate. This process is repeated when the lever 58 moves downwards again. Therefore, during the reciprocating motion of the lever 58, multiple paddles 55 can be used to drive the driven wheel 54 to rotate. The rotation of the driven wheel 54 drives the connected shaft 52 to rotate. This shaft 52, through the meshing relationship between two gears 59, drives another shaft 52 to rotate in the opposite direction. The rotation of both shafts 52 drives the two cleaning rollers 53 to rotate, ensuring that the two cleaning rollers 53 can maintain their position while cleaning the chain 3. The two cleaning rollers 53 continue to rotate, thereby increasing the contact area with the chain 3 per unit time, thus improving the cleaning effect. At the same time, it also avoids the cleaning rollers 53 from continuously cleaning the same part and accumulating too much dirt, which would affect the cleaning effect. When the two cleaning rollers 53 rotate, they contact the two scraper strips 511 respectively. The two scraper strips 511 can scrape the dirt attached to the surface of the two cleaning rollers 53 into the collection box 512, thereby maintaining the cleanliness of the cleaning rollers 53 and ensuring the cleaning effect. The collection box 512 can be disassembled for easy regular cleaning. Operators can also clean the two cleaning rollers 53 regularly to maintain their performance.

[0038] The above embodiments are only used to illustrate the present utility model, and are not intended to limit the present utility model. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present utility model. Therefore, all equivalent technical solutions also fall within the scope of the present utility model. The patent protection scope of the present utility model should be defined by the claims.
