Description

Technical Field

[0001] This invention relates to the field of automatic conveying technology for special grooved belts, and more particularly to an automatic conveying device for grooved belts. Background Technology

[0002] Figure 1 The diagram shows a reaction tank, a key piece of equipment in the production process of a certain product. Made of carbon steel, excluding the tank cover, it can be considered a closed tank measuring 10m long, 0.5m wide, and 0.28m high. There are 250mm x 150mm viewing entrances at both ends of the tank cover. A metal plate is welded to the tank cover, 2cm from the bottom. There are also 25cm long and 15cm wide viewing entrances (also called tank openings) at both ends of the tank cover. Due to the installation configuration, these viewing entrances are 1.6 meters above the ground. During production, oxides and sticky impurities are generated at the bottom of the tank and adhere to the bottom surface. Simultaneously, gas bubbles generated during the internal reaction clump together and float on the upper plate, contributing to a decrease in reaction efficiency along with the impurities. The main problems are as follows:

[0003] First, the reaction process produces a lot of precipitates, which affects production efficiency.

[0004] Second, the large amount of gaseous substances generated during the reaction process are not easily removed in time, which affects production efficiency.

[0005] Third, the reaction is a liquid-liquid surface contact reaction, which is affected by factors such as temperature, pressure, current intensity, flow rate, concentration, contact area, and precipitates and gases produced by side reactions.

[0006] To improve the reaction efficiency of the reaction tank, manual churning is currently used to remove impurities from the bottom of the tank. This involves repeatedly dragging a special churning belt through the tank to increase production efficiency. However, during manual churning, harmful substances inside the reaction tank can quickly escape through the visible inlet. Furthermore, completing the manual churning process for multiple tanks requires approximately 1.5 hours per person, resulting in high labor intensity and significant occupational hazards for workers. Summary of the Invention

[0007] The purpose of this invention is to provide an automatic conveyor belt for grooving, which solves the problems of high labor intensity and strong occupational hazards of the original manual grooving and realizes the automatic grooving process of a single device.

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] An automatic conveyor belt for grooving includes a belt recovery device and a belt feeding device mounted on a device mounting base plate. The device mounting base plate is mounted on an angle-changing device, which is connected to a translation device. The belt feeding device feeds the belt into the belt recovery device.

[0010] Furthermore, the belt recovery device includes a drive motor, a cleaning tank, and a recovery roller. The recovery roller is disposed in the cleaning tank, and the drive motor is connected to the recovery roller to drive the recovery roller to rotate.

[0011] Furthermore, a belt guide roller is installed at the belt outlet of the cleaning tank.

[0012] Furthermore, the belt guide roller includes a belt roller, a roller cover, a belt guide wheel, and a belt roller base.

[0013] Furthermore, the drive motor is mounted on the rear panel of the cleaning tank.

[0014] Furthermore, the belt recovery device also includes a manual crank handle, which is connected to the recovery roller for manually driving the recovery roller to rotate.

[0015] Furthermore, the cleaning tank is also equipped with an overflow port, a bottom flow port, and a cleaning port.

[0016] Furthermore, the belt feeding device includes a belt feeding clamping assembly, a belt guide box, a belt guide box mounting frame, and a belt feeding drive assembly mounted on the feeding device mounting frame, wherein a belt guide box drive motor is mounted on the belt guide box mounting frame.

[0017] Furthermore, the belt feed and clamping assembly includes a belt feed and clamping electric cylinder, a belt feed and clamping driven roller, and a belt feed and clamping driving roller. The belt feed and clamping driving roller is drivenly connected to the belt feed drive assembly, the belt feed and clamping electric cylinder is connected to the belt feed and clamping driven roller, and the belt feed and clamping driven roller is drivenly connected to the belt feed and clamping driving roller.

[0018] Furthermore, the translation device is fixedly mounted on the device bracket.

[0019] Compared with the prior art, the automatic conveyor belt device for grooving provided by the present invention has the following advantages:

[0020] This invention can replace manual labor to automate grooving operations, thereby improving the level of automation, reducing the labor intensity of employees, reducing safety risks, and enhancing the automation level of the company's production line.

[0021] This invention enables the conveyor belt to be transported to the bottom of the reaction tank in a "fast forward, slow backward" manner, thereby removing impurities from the bottom of the tank, improving reaction efficiency, and reducing the labor intensity of workers.

[0022] Furthermore, the original belts were replaced with belts made of new UPE material. These new belts have greater mechanical strength and elongation, are lighter, and have better application performance. Attached Figure Description

[0034] The following detailed description provides further details on specific implementation methods.

[0035] like Figures 2 to 6As shown, this invention provides an automatic conveyor belt for cleaning equipment. This conveyor is connected to a cleaning system and a support base, and is controlled by a control system. The overall dimensions of the conveyor are: length × width × height = 996mm × 1260mm × 2415mm. This invention removes adhesive impurities from the bottom of the equipment by using a reciprocating belt at a variable angle, improving the efficiency of the equipment's chemical reaction and reducing the workload and occupational hazards for workers.

[0036] like Figure 2 As shown, the belt cleaning system consists of a circulating pump, a cleaning fluid tank, and pipeline valves. A certain amount of cleaning fluid is contained inside the belt roller cover. After the belt is cleaned by the spray pipe, it can be submerged in the cleaning fluid for thorough cleaning. During normal circulating spray cleaning, excess cleaning fluid is circulated through the overflow pipe. When the cleaning fluid needs to be replaced, it is drained and replaced via the underflow. A pneumatic diaphragm pump is used as the circulating pump for spray cleaning of the belt.

[0037] The support frame serves to support the belt conveyor and cleaning system equipment, and is made of 304 stainless steel. The structure of the support frame is as follows: Figure 3 As shown.

[0038] The belt control system uses a PLC control system, which can set the speed from 0.1m / s to 1m / s to realize the automatic and manual grooving process of the belt, and has fault alarm, fault diagnosis, and one-button start / stop functions.

[0039] like Figures 4 to 6 As shown, the automatic conveyor belt for grooving includes a system displacement component, an angle-changing component, a belt roller component, a belt reverse feed drive component, a roller angle-changing component, a roller linear displacement component, a belt feed component, a belt guide box, and a guide box displacement component.

[0040] To achieve variable angle grooving and ensure that there are no dead angles in the belt grooving, the belt roller assembly, belt reverse feed drive assembly, roller variable angle assembly, roller linear displacement assembly, belt feed assembly, belt guide box and guide box displacement assembly are installed and fixed as a whole on the variable angle device 4.

[0041] like Figure 4 As shown, the belt recovery device 1 and the belt feeding device 2 are bolted to the device mounting base plate 3, and are arranged at intervals. The device mounting base plate 3 is bolted to the angle changing device 4. The angle changing device 4 is bolted to the translation device 5, and the translation device 5 is fixedly mounted on the device bracket 6.

[0042] like Figure 5 and Figure 6As shown, the belt recovery device 1 includes a drive motor 7, a manual crank 8, a belt guide roller 9 (i.e., a guide roller), a cleaning tank 10, and a recovery roller 11 (i.e., a belt recovery roller). The drive motor 7 is fixed to the side plate of the cleaning tank via a mounting bracket, and the drive motor 7 is connected to the recovery roller 11. The recovery roller 11 is fixed inside the cleaning tank 10 and can be rotated by the drive motor 7. The manual crank 8 is connected to the recovery roller 11, and can be manually rotated by the manual crank 8 in case of a failure of the drive motor 7. The belt guide roller 9 is fixed at the belt outlet (e.g., at the belt exit point). Figure 6 (As shown on the side panel), the belt is lifted and guided. The drive motor 7 is located on the rear panel. It should be noted that... Figure 4 The direction shown is the front, and the drive motor 7 is installed at the back.

[0043] The cleaning tank 10 is equipped with an overflow port 12, a bottom outlet 13, and a cleaning port 14. The overflow port 12 is located in the middle of the cleaning tank 10 to prevent the liquid level from becoming too high. The bottom outlet 13 is located at the lower part of the cleaning tank 10, especially below the overflow port 12, to facilitate the replacement of the cleaning fluid. The cleaning port 14 is located on the front panel of the cleaning tank and can be used to install a spray nozzle. Optionally, the cleaning port 14 is located on the same side as the manual crank handle 8.

[0044] The belt winding assembly includes a belt roller, a roller cover, a belt guide pulley, and a belt roller base. The belt roller base supports and fixes the belt roller cover; the belt roller is installed inside the belt roller cover; the belt guide pulley is installed on the side of the belt roller cover; the roller base is fixedly mounted on a lower mounting plate, which is fixed to a variable angle device. The belt roller is a drive roller, connected to an explosion-proof drive motor for directional belt feeding.

[0045] like Figure 7 and Figure 8 As shown, the belt feeding device 2 includes a feeding device mounting bracket 15, a belt feeding clamping assembly 16, a belt guide box 17, a belt guide box mounting bracket 18, a belt feeding drive assembly 19, and a belt guide box drive motor 20. The belt feeding drive assembly 19 is bolted to the side of the feeding device mounting bracket 15, the belt feeding clamping assembly 16 is bolted to the feeding device mounting bracket 15, and the belt guide box mounting bracket 18 is bolted to the feeding device mounting bracket 15. The belt guide box drive motor 20 is mounted on the side of the belt guide box mounting bracket 18.

[0046] like Figure 8As shown, the belt feed and clamping assembly 16 includes a belt feed and clamping electric cylinder 21, a belt feed and clamping driven roller 22, and a belt feed and clamping driving roller 23. The belt feed and clamping driving roller 23 is driven by the belt feed drive assembly 19. The belt feed and clamping electric cylinder 21 is connected to the belt feed and clamping driven roller 22, and the belt feed and clamping driven roller 22 is driven by the belt feed and clamping driving roller 23. The roller body is made of 316L stainless steel.

[0047] Grooved bearings are installed on both sides of the driven roller (belt feed clamping driven roller 22). The grooved bearings guide the movement and reduce frictional resistance during gap adjustment. The gap between the rollers can be adjusted quickly and easily, ensuring full contact between the belt and the drive roller, and realizing belt translational feeding.

[0048] To minimize roller speed, a roller with a diameter of 60mm is used. An explosion-proof servo motor with P=1.2KW, speed n=3000r / min, without a brake, incremental encoder, and explosion-proof design is selected.

[0049] The belt conveyor operates in a reciprocating motion. Due to the presence of a roller conveyor belt mechanism, the gap between the rollers needs to be increased when the belt moves back. To ensure unobstructed belt movement, the following requirements must be met:

[0050] (1) The feed mechanism drive motor has no holding brake and the reducer has no self-locking;

[0051] (2) The gap between the rollers can be adjusted at any time, and the gap ensures that the belt can be conveyed forward or the belt can be recycled and transported.

[0052] In a folding-back electric cylinder, the motor is mounted parallel to the cylinder, connected by a synchronous pulley. In this configuration, the servo motor (stepper motor) axis is mounted parallel to the ball screw axis, and the two are connected by a synchronous pulley. The folding-back mounting design results in a shorter overall length of the electric cylinder, making it suitable for applications with limited space. It also allows for small-range adjustment of the cylinder's reduction ratio via the synchronous pulley.

[0053] like Figure 9 As shown, the belt guide box 17 is responsible for accurately conveying the belt to the bottom of the belt. The guide box translation rack 24 is installed on the bottom surface of the belt guide box 17, and the guide box translation rack 24 meshes with the gear 25 directly connected to the drive motor.

[0054] The grooved belt is made of 6mm high molecular weight polyethylene sheet and is a non-rigid product. In order to allow the belt to enter the internal space of the equipment smoothly, a groove box is specially designed to guide and introduce the belt.

[0055] Firstly, polytetrafluoroethylene (PTFE) has a lower coefficient of friction than other engineering plastics, making it the material with the lowest known coefficient of friction among practical sliding surface materials. It is an ideal lubricant. Therefore, PTFE material can meet insulation requirements while minimizing the coefficient of friction between the belt and the guide box.

[0056] Secondly, based on the dielectric properties of polytetrafluoroethylene, as follows:

[0057]

[0058] The guide box is 67cm long and has a cross-sectional area of ​​32cm2. The insulation resistance R of the guide box connected to the equipment is R = volume resistivity × length / cross-sectional area = 1015 × 0.67 / (0.0032) = 212515.63 = 2.1MΩ.

[0059] The purpose of setting up the guide box displacement device is: when the belt enters the equipment, it needs to be guided and introduced by the guide box. When the belt finishes its work and is removed for cleaning, the guide box is removed from the equipment together, so as not to affect the normal operation of the original equipment.

[0060] The guide box displacement device includes a drive assembly, a fixed bracket, a transmission mechanism, and a guiding mechanism. The drive assembly consists of a servo motor and a worm gear reducer. The belt guide box is mounted and fixed on the feed bracket, guiding the forward or backward movement of the belt.

[0061] The displacement device has a 45° tilt angle. To prevent self-displacement under gravity after the mechanism stops moving, a worm gear reducer is selected to achieve self-locking. The reducer's reduction ratio is i=10. A servo motor without a brake can be selected. The slot box displacement mechanism uses a rack and pinion drive (guide box translation rack 24 and gear 25).

[0062] Optionally, the automatic conveyor belt system also includes a belt reversing feed assembly, which comprises a servo motor (explosion-proof type), a planetary reducer, and a mounting base. The servo motor has a power of 1.8KW, a rated speed of 3000rpm, is a non-brake type, and is equipped with an incremental encoder. It is fitted with an i=10 planetary reducer. The feed assembly and the reversing roller base are mounted together on the lower mounting plate; the belt roller feed device and roller gap adjustment device are mounted on the feed bracket. When the roller gap adjustment device is adjusted to a small gap, the rollers press the belt tightly, and the belt moves forward under the drive of the feed drive motor; the reversing feed motor drives the belt roller to rotate, thus retracting the belt.

[0063] Meanwhile, the grooving belt uses a new type of UPE material, and belts with thicknesses of 5mm, 6mm, 8mm, and 10mm have been designed and manufactured. Belts with a thickness of 6mm and below are 6m long, while belts with a thickness of 8mm and above are assembled using a three-section welding method due to logistical constraints. The belt head is designed with a curved "T" shape, 140mm wide and 700mm or 1000mm long, to enhance belt strength and facilitate slag removal and defoaming. The remaining sections of the belt are reduced to 70mm wide to further reduce weight and lower worker workload. The edges are rounded and frosted to improve grip friction and operational comfort.

[0064] After practical testing and application, a belt thickness of 6mm was finally selected. In field trials, the test belt lasted for more than a year without damage. The original belt generally had a lifespan of two weeks, requiring two rolls of old belt every four months, weighing 150kg. In contrast, the new belt of the same length weighs less than one-tenth of the old belt, greatly reducing the labor intensity of employees and the generation of industrial waste.

[0065] For example, through experimentation and improvement, the final determination of the grooving skin as the driving force was made:

[0066] (1) The middle position is moved back and forth 10 times. The position data is translated: position 10mm, speed 20mm / S, angle: 0.0 degrees, speed 15mm / S; conveying: position ±750mm, speed 750mm / S.

[0067] (2) The left position is moved back and forth 10 times. The position data is translated: position -14mm, speed 20mm / s, angle: 3.4, speed 15mm / s; conveying: position ±750mm, speed 750mm / s.

[0068] (3) Right side position 10 times, position data translation: position 62mm, speed 20mm / S, angle: 0.0, speed 15mm / S; conveying: position ±750mm, speed 750mm / s.

[0069] (4) After the above three positions are completed, the conveyor shaft advances 750mm and performs the next set of "left, middle and right" 10 round trips each, and continues in this cycle until it reaches the drum setting position -372 and stops. The belt is then automatically retracted and cleaned.

[0070] Based on the specific conditions of the field test, a comparison chart of the voltage changes in the tank before and after the test is drawn, as shown below. Figure 8 As shown.

[0071] according to Figure 10It can be seen that with the continuous optimization and improvement of the process, the process parameters of the experimental tank were significantly improved after the tumbling was completed. This indicates that the automatic conveyor belt for tumbling has a certain promoting effect on the exothermic chemical reaction in the experimental tank. With the application of the automatic conveyor belt for tumbling, the original manual tumbling method can be eliminated, greatly reducing the labor intensity of employees.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention.
