Description

Technical Field

[0001] The present invention relates to the technical field of material conveying equipment, in particular to an industrial automated material conveying device. Background Art

[0002] In the modern industrial production system, material conveying equipment serves as the link connecting various production links. In the automated scenario of high-intensity continuous operation, belt conveyors have become key transmission equipment in discrete manufacturing, food processing, mining and metallurgical engineering and other fields due to their simple structure and long conveying distance.

[0003] As a critical link in the production process, the operational stability of material conveying equipment directly impacts production efficiency and product quality. Traditional belt conveyors typically consist of a drive mechanism, a transmission belt, and a support frame. While these systems meet basic material transport requirements, long-standing technical bottlenecks severely restrict the intelligent development of these devices in high-intensity, continuous industrial environments. The transmission belt, as the core power transmission medium, ensures stable operation, directly impacting the overall performance of the entire machine.

[0004] Traditional belt conveyors face two major technical problems in practical applications: First, the conveyor belt will become loose and slip due to aging after long-term use, affecting the normal and stable transmission of materials. The transmission belt is prone to elastic attenuation due to long-term cyclic loads, resulting in dynamic tension imbalance; second, pollutants such as dust particles and oil residues attached during the conveying process are prone to form stubborn deposits on the surface of the transmission belt, which not only aggravates the wear of the conveyor belt but also affects hygiene standards.

[0005] Existing tension adjustment devices often utilize passive mechanical mechanisms, employing adjustable squeeze wheels to allow personnel to adjust the tension of the conveyor belt (Announcement No. CN219506892U, employing a method where a screw is manually rotated to drive a top roller to adjust the conveyor belt). However, this conventional manual adjustment method for conveyor belts in automated material conveying equipment suffers from shortcomings such as response lag and low adjustment accuracy. It is unable to detect and compensate for tension loss in real time, leading to frequent sudden slippage and shutdown accidents. Conventional cleaning solutions often rely on manual periodic cleaning or the addition of independent cleaning devices, increasing equipment downtime and significantly increasing operating costs. Especially for industries with stringent cleanliness requirements, such as food and pharmaceuticals, residual impurities can also cause cross-contamination. Summary of the Invention

DETAILED DESCRIPTION

[0022] In order to better understand the above technical solution, the following will be described in detail with reference to the accompanying drawings and specific implementation methods. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them.

[0023] Example 1 like Figures 1 to 5 As shown, an industrial automated material conveying device proposed in this embodiment, the belt conveyor includes a U-shaped frame 1, a transmission roller, a conveyor belt 101 and a conveying motor. A U-shaped steel structure frame is adopted, and its front and rear side plates are arranged in parallel to form a guide channel. The two transmission rollers are rotatably installed at both ends of the U-shaped frame 1 and are symmetrically arranged along the transverse direction of the U-shaped frame 1. The driving wheel is rotatably installed between the front and rear side plates of the U-shaped frame 1 through a bearing assembly. Any of the transmission rollers is coaxially connected to the output shaft of the driving motor through a coupling, and the flexible conveyor belt 101 is annularly sleeved on the outer periphery of the two transmission rollers to form a closed-loop conveying path.

[0024] A plurality of support rollers 102 are rotatably mounted between the front and rear inner walls of the U-shaped frame 1 at equal intervals, each of which is in active contact with the inner top of the conveyor belt 101, thereby providing a rotational support for the inner top of the conveyor belt 101 and preventing it from falling. An integrated rotary-cleaning, external-discharge, self-tensioning mechanism is installed in the U-shaped frame 1 and below the conveyor belt 101; The integrated rotary cleaning type external discharge tension self-adjusting mechanism includes a mounting plate 2, a lifting plate 4, a PLC controller 201, a vertical guide lifting drive assembly, a U-shaped seat 5, a pressure measuring vertical guide assembly, a horizontal support 6, a round roller brush 8, a leveraged direction-changing linkage rotary drive assembly, and a slag removal guide assembly; The mounting plate 2 is fixedly mounted on the bottom inner wall of the U-shaped frame 1, and a lifting plate 4 is provided above it; The PLC controller 201 is fixedly mounted on the top of the mounting plate 2; The vertical guide lifting drive assembly is fixedly connected between the lifting plate 4 and the mounting plate 2 and is electrically connected to the PLC controller 201; Two groups of U-shaped seats 5 are provided, and the U-shaped seat 5 on the right is fixedly connected to the top of the lifting plate 4. A rotating shaft 502 is rotatably embedded between the front and rear inner walls of the U-shaped seat 5. A squeezing wheel 501 is fixedly sleeved on the rotating shaft 502. The outer adhesive sleeve of the squeezing wheel 501 is provided with an anti-slip rubber sleeve 503 that is in tight contact with the bottom of the conveyor belt 101; the anti-slip rubber sleeve 503 is used to be rotated by friction when the conveyor belt 101 rotates, thereby driving the corresponding squeezing wheel 501 and the rotating shaft 502 to rotate; The pressure measuring vertical guide assembly is installed between the top of the lifting plate 4 and the U-shaped seat 5 on the left, and is electrically connected to the PLC controller 201; the pressure measuring vertical guide assembly is used to monitor the tightening pressure on the bottom of the conveyor belt 101 through the U-shaped seat 5 and the extrusion wheel 501 on the left, and transmit the pressure value to the PLC controller 201. The vertical guide lifting drive assembly is used to be controlled by the PLC controller 201 to drive the lifting plate 4 to automatically move upward when the pressure value is lower than a preset value, so as to drive the two extrusion wheels 501 to increase the extrusion force on the conveyor belt 101 upward until the preset pressure value is reached, thereby automatically and timely and accurately regulating the tension of the conveyor belt 101; There are two sets of horizontal supports 6 and they are fixedly connected to the right side of the U-shaped seat 5 on the right side. The two adjacent sides of the horizontal supports 6 are rotatably embedded with a connecting shaft 601. The round roller brush 8 is connected between the two connecting shafts 601 and contacts the bottom of the conveyor belt 101; The leveraging type reversing linkage rotary drive assembly is installed outside the right rotating shaft 502 and the front connecting shaft 601; the leveraging type reversing linkage rotary drive assembly is used to drive the front connecting shaft 601 to rotate when the right rotating shaft 502 rotates, and the connecting shaft 601 drives the round roller brush 8 to rotate in the direction opposite to the bottom of the conveyor belt 101 to clean the impurities adhering to the bottom thereof; The slag removing and guiding assembly is installed on the right side of the lifting plate 4 and is in active contact with the round roller brush 8. The slag removing and guiding assembly is used to scrape off the impurities adhering to the outside of the round roller brush 8 and guide them downward to remove them when the brush is rotated.

[0025] Furthermore, the round roller brush 8 is fixedly connected between the two connecting shafts 601 by welding.

[0026] Furthermore, if Figure 3As shown, the vertical guide lifting drive assembly includes an inner rod 301, an outer tube 302 and an electric telescopic rod 3. The number of the inner rods 301 is four and they are fixedly connected to the top of the mounting plate 2 in a rectangular shape. The number of the outer tubes 302 is four and they are fixedly connected to the bottom of the lifting plate 4 in a rectangular shape. The outer tubes 302 are slidably sleeved on the corresponding inner rods 301. The bottom end and the extended end of the electric telescopic rod 3 are fixedly connected to the top of the mounting plate 2 and the bottom of the lifting plate 4 respectively. The electric telescopic rod 3 is electrically connected to the PLC controller 201 through a wire. In this embodiment, a limiting hole is provided on the right inner wall of the outer tube 302, and a limiting block is fixedly connected to the top right side of the inner rod 301 and is slidably connected to the corresponding limiting hole, thereby limiting the outer tube 302 and preventing it from falling off. In this embodiment, the inner rod 301, the outer tube 302 and the electric telescopic rod 3 cooperate. When the pressure value received and read by the PLC controller 201 is lower than the preset value, it controls the electric telescopic rod 3 to start in the forward direction, so that it drives the lifting plate 4 to move upward. The lifting plate 4 drives the four outer tubes 302 to slide vertically on the corresponding inner rod 301 respectively to perform vertical guiding work. The lifting plate 4 drives the two extrusion wheels 501 to move upward through the two U-shaped seats 5 to increase the extrusion force on the conveyor belt 101. Until the preset pressure value is reached, the PLC controller 201 controls the electric telescopic rod 3 to close, so as to achieve the effect of automatically controlling the pressure and tensioning the conveyor belt 101 when it is loose, thereby reducing the phenomenon of loosening and slipping of the conveyor belt 101 during industrial automation material transportation, and improving the degree of automation, timeliness and stability of adjustment.

[0027] Furthermore, if Figure 1 and 3 As shown, the pressure measuring vertical guide assembly includes a rectangular sleeve 401 and a digital pressure sensor 402. The rectangular sleeve 401 is fixedly connected to the top left side of the lifting plate 4 and is slidably sleeved on the outer bottom of the left U-shaped seat 5. The digital pressure sensor 402 is embedded and fixed on the top left side of the lifting plate 4 and fixedly connected to the bottom of the left U-shaped seat 5. The digital pressure sensor 402 is electrically connected to the PLC controller 201 through a wire. In this embodiment, through the cooperation of the rectangular sleeve 401 and the digital pressure sensor 402, when the extrusion wheel 501 and the conveyor belt 101 are squeezed, since the force is mutual, the conveyor belt 101 also presses the extrusion wheel 501 downward, and the extrusion wheel 501 on the left transmits the pressing force to the digital pressure sensor 402 through the corresponding U-shaped seat 5. The digital pressure sensor 402 detects the extrusion force and transmits it to the PLC controller 201 pressure value, so that the PLC controller 201 automatically performs extrusion adjustment control according to the pressure value.

[0028] It should be noted that the electric telescopic rod 3 and the digital pressure sensor 402 are both electrically connected to the PLC controller 201 via wires. The technology of establishing an electrical connection by direct wire connection, being controlled by the PLC controller 201, and directly transmitting corresponding data is a well-known and mature method of conventional wire control of existing controllers, and will not be described in detail here. The PLC controller 201 preferably adopts the Delta DVP series PL model DVP04AD-H3, which has its own communication industrial wire port and can be directly connected to the digital pressure sensor 402 via wires. The digital pressure sensor 402 preferably adopts a plate-type (compression-type) digital weighing sensor of the Transcell BSS series, mainly because the digital weighing sensor has an integrated ADC that converts the signal into a digital signal and outputs the extrusion pressure value for direct reading and reception by the PLC controller 201. In addition, as for the power supply of the electric telescopic rod 3, the digital pressure sensor 402 and the PLC controller 201, since there is no shortage of power supply measures at the industrial automation material transportation site, based on the existing mains power supply resources on site, the mains cables on site are used to connect to the power input interface of the above-mentioned electrical components through conventional power distribution devices such as electrical component power cables to form a complete power supply circuit, which is powered by conventional on-site cable basic connections. These are all conventional, mature and well-known means and will not be elaborated on here.

[0029] Furthermore, if Figure 3 and 4 As shown, the leveraging type change direction linkage rotation drive assembly includes a gear 701, a sprocket 702, a chain 703, a circular shaft 7, a first blocking shield 704 and a second blocking shield 705. The circular shaft 7 is rotatably mounted on the front side of the U-shaped seat 5 on the right side. There are two gears 701 and they are fixedly sleeved on the rotating shaft 502 and the circular shaft 7 on the right side. The two gears 701 are meshed on the sides close to each other. There are two sprockets 702 and they are fixedly sleeved on the circular shaft 7 and the connecting shaft 601 on the front side. The chain The bar 703 is transmission-connected to the two sprockets 702, the second guard shield 705 is fixedly connected to the front side of the front cross support 6, the first guard shield 704 is fixedly connected to the front side of the right U-shaped seat 5 and communicates with the left side of the second guard shield 705, the right sprocket 702 and chain 703 are both located in the second guard shield 705, the gear 701 and the left sprocket 702 are both located in the first guard shield 704, and the left sprocket 702 is located in front of the lower gear 701; In this embodiment, by cooperating with the gear 701, the sprocket 702, the chain 703, the circular shaft 7, the first shield 704 and the second shield 705, when the conveyor belt 101 is rotating in the forward direction, its bottom is in the left-moving state, and the conveyor belt 101 friction drives the extrusion wheel 501 at the bottom to rotate in the reverse direction. When the extrusion wheel 501 drives the corresponding rotating shaft 502 to rotate in the reverse direction, the rotating shaft 502 on the right drives the upper gear 701 to rotate in the reverse direction, and the upper gear 701 drives the lower gear 701 meshing with it to rotate forward, and the lower gear The wheel 701 drives the circular shaft 7 to rotate forward, and the circular shaft 7 drives the front connecting shaft 601 to rotate forward through the two sprockets 702 and the chain 703. The connecting shaft 601 drives the circular roller brush 8 to rotate forward. The circular roller brush 8 rotates forward to realize the cleaning of impurities adhered to the bottom of the conveyor belt 101 in the opposite direction of the movement of the bottom of the conveyor belt 101, thereby reducing the phenomenon that more impurities adhere to the outside of the conveyor belt 101 and affecting its use, and improving the use effect. In addition, the use of the rotating brush in the opposite direction of movement can achieve better relative friction and provide a better brushing effect.

[0030] Furthermore, if Figure 3 and 4 As shown, the slag removal and guiding assembly includes a connecting plate 9, a rubber scraper 901, a slag cover 902, a slag blocking piece 904 and a slag discharge pipe 903. The left side of the connecting plate 9 is fixedly connected to the right side of the lifting plate 4. The rubber scraper 901 is tilted and fixedly connected to the right side of the connecting plate 9, and is in active contact with the left bottom of the round roller brush 8. The slag cover 902 is located below the round roller brush 8. The slag discharge pipe 903 is connected and fixed to the bottom of the slag cover 902. The mounting plate 2 is fixedly sleeved on the outside of the slag discharge pipe 903. The bottom end of the slag discharge pipe 903 extends to the bottom of the U-shaped frame 1. The slag blocking piece 904 is fixedly connected to the top right side of the slag cover 902 and is located on the right side of the round roller brush 8. In this embodiment, the connecting plate 9, rubber scraper 901, slag cover 902, slag blocking sheet 904 and slag discharge pipe 903 cooperate with each other. When the round roller brush 8 rotates, its own outer bristles rub against the right side of the inclined rubber scraper 901, and the rubber scraper 901 is used to squeeze and scrape off the impurities adhering to the outer side of the round roller brush 8. The slag blocking sheet 904 is used to block the impurities brushed off by the rotating round roller brush 8 on the right side, so that the brushed and scraped impurities fall directly downward into the slag cover 902, and then discharged downward through the slag discharge pipe 903. Personnel can place a collection box for slag collection under the slag discharge pipe 903, so as to achieve the effect of automatically scraping off the impurities adhering to the outer side of the round roller brush 8 and guiding them downward for removal when the brush is rotated.

[0031] The embodiment can monitor the tension of the conveying belt 101 and automatically and timely adjust the precise pressure tension when it is loose, reduce the phenomenon of the conveying belt 101 slipping when it is loose in the industrial automatic material conveying work, improve the adjustment automation degree, timeliness and efficiency, and then improve the long-term continuous use stability, and facilitate the integrated automatic bottom effective brush cleaning of impurities of the conveying belt 101 during use, reduce the phenomenon that more impurities adhere to the outside to affect the normal use, improve the use effect and the cleanliness of the conveying belt 101 during use, and ensure the real-time cleaning work during application by using the power-assisted and integrated operation mode of the conveying belt 101.

[0032] The use method of the embodiment is: when the industrial automatic material conveying device is used, the pressure value range of the corresponding opening and closing of the electric telescopic rod 3 is pre-set by the PLC controller 201 according to the extrusion tension required by the conveying belt 101, when the extrusion wheel 501 is extruded with the conveying belt 101, the force is mutual, and the conveying belt 101 also presses the extrusion wheel 501 downward, the left extrusion wheel 501 transmits the pressing force to the digital pressure sensor 402 through the corresponding U-shaped seat 5, the rectangular sleeve 401 is used for vertical positioning of the left U-shaped seat 5, the digital pressure sensor 402 detects the extrusion force and transmits the pressure value to the PLC controller 201, when the received and read pressure value is lower than the preset value, the PLC controller 201 controls the electric telescopic rod 3 to start in the positive direction, so that the driving lifting plate 4 moves upward, the four outer pipes 302 are respectively vertically slid on the corresponding inner rods 301, the vertical guide work is performed, the lifting plate 4 drives the digital pressure sensor 402 to move upward, the digital pressure sensor 402 and the lifting plate 4 jointly drive the two U-shaped seats 5 to move upward, the two U-shaped seats 5 drive the two extrusion wheels 501 to move upward, and the extrusion force on the conveying belt 101 is increased, because the force is mutual, the increase of the extrusion force represents the synchronous increase of the detection and transmission of the digital pressure sensor 402 to the pressure, when the preset pressure value is reached, the PLC controller 201 controls the electric telescopic rod 3 to be closed, so that the effect of automatically and timely adjusting the precise pressure tension of the conveying belt 101 when it is loose is realized, the phenomenon of the conveying belt 101 slipping when it is loose in the industrial automatic material conveying work is reduced, the adjustment automation degree, timeliness and efficiency are improved, and then the long-term continuous use stability is improved; When the conveyor belt 101 rotates forward to transport materials, its bottom is in a left-moving state, and the conveyor belt 101 drives the two extrusion wheels 501 at the bottom to rotate in the opposite direction through the friction of the two anti-slip rubber sleeves 503. The extrusion wheels 501 drive the corresponding rotating shaft 502 to rotate in the opposite direction, and the rotating shaft 502 on the right drives the upper gear 701 to rotate in the opposite direction. The upper gear 701 drives the lower gear 701 meshing with it to rotate forward, and the lower gear 701 drives the circular shaft 7 to rotate forward. The circular shaft 7 drives the front connecting shaft 601 to rotate forward through the two sprockets 702 and the chain 703. The connecting shaft 601 drives the round roller brush 8 to rotate forward. The round roller brush 8 is used to rotate forward to realize the cleaning of impurities adhered to the bottom of the conveyor belt 101 in the opposite direction of its bottom movement. When the round roller brush 8 rotates, its outer bristles rub against the right side of the inclined rubber scraper 901, and the rubber scraper 901 is used to clean the round roller brush 8. The impurities adhered to the outside are squeezed and scraped off, and the slag blocking piece 904 is used to block the impurities brushed off by the rotating round roller brush 8 on the right side, so that the brushed and scraped impurities fall directly downward into the slag collecting cover 902, and then discharged downward through the slag discharge pipe 903. The staff can place a collection box for slag collection under the slag discharge pipe 903, so that when the conveyor belt 101 is in use, the bottom of the conveyor belt 101 can be automatically and effectively rotated to clean the impurities and concentrate the impurities downward for removal, reducing the phenomenon that more impurities adhere to the outside of the conveyor belt 101 and affecting its normal use, improving the use effect, and using the rotating brush method with the opposite movement direction, better relative friction can be achieved, providing better brushing effect, and improving the cleanliness of the conveyor belt 101 when in use, and there is no need to equip a separate power equipment for the rotating brush. It can directly ensure the integrated synchronous operation and coordinated application with the conveyor belt 101 by leveraging force, ensuring real-time cleaning work during application. Example 2 like Figures 6 and 7 As shown, this embodiment is based on the embodiment one, and its difference from the embodiment one is that: the round roller brush 8 is detachably connected between the two connecting shafts 601, and the front and rear ends of the round roller brush 8 are fixedly connected to the clamping sleeve 801 with an opening at the outer end. The two clamping sleeves 801 are symmetrically arranged, and the opening directions are arranged facing each other. The ends close to the two connecting shafts 601 are respectively movably inserted into the corresponding clamping sleeves 801, and a clamping groove 602 is provided on the top of the connecting shaft 601. A knob-type bolt 802 is movably mounted in the clamping groove 602, and a threaded hole threadedly connected to the corresponding knob-type bolt 802 is provided on the top of the clamping sleeve 801. A rubber gasket 803 is bonded and fixed to the inner wall of the top of the knob-type bolt 802, which is in tight contact with the top of the corresponding clamping sleeve 801.

[0033] In this embodiment, the circular roller brush 8 can be disassembled, assembled, and replaced separately when the circular roller brush 8 is severely worn, thereby further improving the flexibility of use.

[0034] The method of use of this embodiment is as follows: the difference from the first embodiment is that it also has the following functions: through the detachable connection between the connecting shaft 601 and the round roller brush 8, the knob-type bolt 802 is subsequently rotated in the opposite direction to rotate it in the corresponding threaded hole and move upward, so that the bottom end of the knob-type bolt 802 is separated from the corresponding clamping groove 602 upward, and the connection state of the connecting shaft 601 is released. The clamping sleeve 801 can be pushed a little to separate it from the corresponding connecting shaft 601 through the right opening, and the round roller brush 8 can be taken out and replaced. During installation, the clamping sleeve 801 is clamped to the outer side of the corresponding connecting shaft 601, and then the knob-type bolt 802 is rotated forward to make its bottom end clamped in the clamping groove 602. The knob bolt 802 drives the corresponding rubber gasket 803 to be squeezed against the outer side of the clamping sleeve 801, and the knob bolt 802 is elastically tightened and anti-slip, thereby achieving connection and locking with the connecting shaft 601, so that the round roller brush 8 can be disassembled and replaced separately when it is severely worn in the future, thereby further improving the flexibility of use.
