Description

Technical Field

[0001] This invention relates to the technical field of electrostatic dust removal equipment for food processing, and specifically to an electrostatic dust removal device for food packaging conveyor belts. Background Technology

[0002] Hygiene standards for food processing production lines are a crucial indicator of food safety, with dust removal being a fundamental standard. Conveyor belt systems, besides being susceptible to dust accumulation due to environmental factors, also attract fine dust particles from powdered or cake-shaped raw materials. Therefore, conveyor lines are equipped with corresponding dust removal devices for real-time dust collection. Electrostatic precipitators, which work by electrostatic adsorption, can effectively adsorb tiny dust particles, preventing their dispersion and removing dust that conventional cleaning methods cannot. Based on this, a dust removal system suitable for food packaging processing needs to be designed, combining an electrostatic precipitator and a belt conveyor line. Summary of the Invention

[0003] The purpose of this invention is to address the deficiencies and shortcomings of existing technologies by providing an electrostatic dust removal device for food packaging conveyor belts. This device achieves electrostatic adsorption and cleaning of dust on the conveyor belt by setting up an alternating electrostatic plate structure and a corresponding collection and cleaning structure. At the same time, it can also clean the electrostatic plates with dust adhering to them without affecting the normal operation of the equipment.

[0004] To achieve the above objectives, the present invention adopts the following technical solutions:

[0005] It includes a frame, wherein a belt roller is spun on the central crossbeam of the frame via bearings, and a conveyor belt is wound around the belt roller; it also includes:

[0006] The mounting frame is mounted above the conveyor belt and is spun onto the upper crossbeam of the frame via a rotating shaft.

[0007] The electrostatic adsorption plate consists of two plates, which are symmetrically fixed at the upper and lower ends of the mounting frame, with the lower electrostatic adsorption plate movably abutting against the upper surface of the conveyor belt.

[0008] The collection mechanism is mounted on the frame and is supported on the upper electrostatic adsorption plate.

[0009] During use, the mounting frame intermittently drives the two electrostatic adsorption plates to rotate, causing the two electrostatic adsorption plates to alternately press against the upper surface of the conveyor belt. After the material is fed, the conveyor belt passes through the electrostatic adsorption plates pressing against the belt surface, thereby adsorbing the dust on the conveyor belt. After the electrostatic adsorption plates press against the conveyor belt and adsorb the dust for a period of time, the electrostatic adsorption plates with dust adsorbed on them rotate to connect with the collection mechanism, and the collection mechanism cleans and collects the dust on the electrostatic adsorption plates.

[0010] Preferably, the collection mechanism comprises:

[0011] A support frame is fixedly mounted on the machine frame and is mounted above the mounting frame.

[0012] End baffles, wherein there are two end baffles that are symmetrically fixed at the front and rear ends of the support frame, and the electrostatic adsorption plate on the upper side is sandwiched between the end baffles on the front and rear sides.

[0013] Side baffles, wherein there are two side baffles arranged symmetrically on the left and right, and the electrostatic adsorption plate on the upper side is sandwiched between the left and right side baffles.

[0014] A drive assembly is mounted on a support frame, and a side baffle is mounted on the drive assembly.

[0015] A slide rail stepping system, wherein the slide rail stepping system is fixedly mounted on a support frame;

[0016] The brush bar is fixedly mounted on the sliding seat of the slide rail stepping system, and the lower side of the brush bar is movably abutted against the upper surface of the electrostatic adsorption plate.

[0017] In use, the two side baffles are opened by the drive assembly, and then the electrostatic adsorption plate is rotated by the mounting bracket to replace it. The electrostatic adsorption plate that was originally pressed against the conveyor belt is rotated and moved between the two side baffles. Then, the two side baffles are closed by the drive assembly. At this time, the side baffles and the end baffles cooperate to clamp the electrostatic adsorption plate. Then, the brush bar is moved by the slide rail stepping system. The brush bar sweeps the upper surface of the clamped electrostatic adsorption plate to clean and collect the dust adhering to the electrostatic adsorption plate.

[0018] Preferably, the driving component comprises:

[0019] The transmission rods are two in number, and the two transmission rods are respectively screwed onto the support frame via a rotating shaft, and the two transmission rods are arranged in a cross manner;

[0020] A guide rod is fixedly mounted on the outer side wall of the side baffle.

[0021] The guide sleeves are arranged in pairs and are screwed onto both ends of the transmission rod via bearings. The guide sleeve at one end of the transmission rod is movably fitted onto the guide rod on one side baffle, and the guide sleeve at the other end of the transmission rod is movably fitted onto the guide rod on the other side baffle.

[0022] The transmission component is mounted on the support frame, and the two transmission rods are connected by the transmission component through the swivel shafts.

[0024] In use, one of the transmission rods is driven to rotate by a reciprocating push rod, which in turn drives the other transmission rod to rotate through a transmission component. The two transmission rods rotate in opposite directions. The transmission rods are connected to the guide rods on the side baffles through guide sleeves. When the two intersecting transmission rods rotate, the side baffles on both sides are moved by the guide sleeves at both ends, and the guide sleeves slide on the guide rods.

[0025] Preferably, the transmission component comprises:

[0026] The gearbox is fixedly mounted on a support frame, and the shafts of the upper and lower transmission rods are respectively screwed onto the upper and lower end plates of the gearbox via bearings.

[0027] The drive gears are two in number and are respectively fixed on the rotating shafts of the upper and lower transmission rods, and the drive gears are located inside the gearbox.

[0028] The reversing gear is spun onto the inner wall of the gearbox via a rotating shaft, and its upper and lower sides are respectively meshed with the driving gears on the upper and lower sides.

[0029] In use, the reciprocating push rod drives the rotating transmission rod, which in turn drives the drive gear connected to its shaft to rotate. This drive gear then drives the drive gear on the shaft of another transmission rod to rotate through the reversing gear. The two drive gears rotate in opposite directions, thus driving the other transmission rod to rotate, and the two transmission rods rotate in opposite directions.

[0030] Preferably, a beam frame is fixedly installed on the middle crossbeam of the frame, a vibrating motor is fixedly installed on the beam frame, a vibrating plate is fixedly installed on the output shaft of the vibrating motor, and the vibrating plate is movably abutted against the lower surface of the upper belt surface of the conveyor belt. A brush roller is rotatably installed on the upper crossbeam of the frame via a rotating shaft, and the brush roller is movably abutted against the upper belt surface of the conveyor belt. A tension buffer assembly is installed on the lower crossbeam of the frame, and the tension buffer assembly is configured to cooperate with the lower belt surface of the conveyor belt.

[0031] Preferably, the tension-relaxation buffer assembly comprises:

[0032] A rotating frame, wherein the rotating frame is spun onto the lower crossbeam of the machine frame via a rotating shaft;

[0033] A torsion spring is sleeved on the rotating shaft of the rotating frame, wherein one of the torsion spring's legs is fixedly mounted on the frame, and the other leg of the torsion spring is fixedly mounted on the rotating frame.

[0034] The guide rollers are two in number, arranged left and right, and respectively mounted on the lower crossbeam of the frame by bearings;

[0035] The support roller is spun onto the movable end of the rotating frame via a bearing and is positioned between the guide rollers on the left and right sides. The lower surface of the conveyor belt is wound around the upper surface of the guide roller, and the surface of the conveyor belt located between the guide rollers on both sides is wound around the lower surface of the support roller.

[0036] During use, the upper surface of the conveyor belt is struck by a vibrating plate to loosen the dust that adheres to the belt surface. When the vibrating plate strikes the conveyor belt surface, the conveyor belt surface vibrates and undergoes tension and relaxation. The lower surface of the conveyor belt is supported by two guide rollers and pressed downward against the rotating frame by a torsion spring. The rotating frame presses the conveyor belt surface between the two guide rollers downward through a support roller. Thus, when the conveyor belt surface tensions and relaxes, the tension and relaxation movement of the conveyor belt surface is buffered by the support roller.

[0037] Preferably, the frame is provided with two clamping rollers spun around a shaft, and the two clamping rollers are arranged vertically, with the upper surface of the conveyor belt clamped between the upper and lower clamping rollers.

[0038] Compared with the prior art, the beneficial effects of the present invention are:

[0039] 1. This device uses alternating electrostatic adsorption plates to remove dust from the conveyor belt after each cycle of dust removal by a single electrostatic adsorption plate. The plate with a large amount of dust adhering to it is then lifted for cleaning and collection.

[0040] 2. This device is equipped with end baffles and foldable side baffles for the cleaning part of the electrostatic adsorption plate, so that dust and other materials can be intercepted and collected through the box structure formed by the end baffles and side baffles during the dust cleaning work.

[0041] 3. This device is designed to address the potential adhesion of dirt and grime on the conveyor belt by using a vibrating plate to beat the belt surface and vibrate it off. In addition, it is equipped with a rotating frame, support rollers, and guide rollers for support, thereby providing cushioning and support to the conveyor belt surface when it vibrates and relaxes.

[0077] The tension and relaxation buffer assembly 13 includes:

[0078] Rotating frame 13-1, wherein the rotating frame 13-1 is spun onto the lower crossbeam of frame 1 via a rotating shaft;

[0079] Torsion spring 13-2 is sleeved on the rotating shaft of rotating frame 13-1, wherein one column of torsion spring 13-2 is fixedly mounted on frame 1, and the other column of torsion spring 13-2 is fixedly mounted on rotating frame 13-1.

[0080] Guide roller 13-3, there are two guide rollers 13-3, and the two guide rollers 13-3 are arranged left and right and respectively rotated on the lower crossbeam of the frame 1 by bearings;

[0081] The support roller 13-4 is spun onto the movable end of the rotating frame 13-1 via a bearing, and is positioned between the guide rollers 13-3 on the left and right sides. The lower surface of the conveyor belt 3 is wound around the upper surface of the guide roller 13-3, and the surface of the conveyor belt 3 located between the guide rollers 13-3 on both sides is wound around the lower surface of the support roller 13-4.

[0082] There are several brush rollers 12, and the brush rollers 12 are spun on the upper crossbeam of the frame 1 through bearings. The brush rollers 12 are movably abutted against the upper belt surface of the conveyor belt 3. The rotating shaft of the brush rollers 12 is connected to an external drive motor.

[0083] Clamping rollers 14, there are two clamping rollers 14, and the clamping rollers 14 are arranged vertically and screwed onto the frame 1 by bearings. The upper belt surface of the conveyor belt 3 is clamped between the upper and lower clamping rollers 14.

[0084] By adopting the technical solution disclosed in this invention, the following can be achieved:

[0085] When using this device, install the device and connect the conveyor belt 3 section located to the right of the clamping roller 14 to the production line for material conveying. The length of this conveyor belt 3 section can be extended according to the actual needs of the production line.

[0086] After the conveyor belt 3 completes the material conveying, the conveyor belt 3 moves around from below the belt roller 2 to the upper left side and steps to the right. The vibration motor 10 drives the vibration plate 11 to work and beat the left end of the upper belt surface of the conveyor belt 3, vibrating and loosening the dirt stuck on the conveyor belt 3. Then the upper belt surface of the conveyor belt 3 moves to the right and passes under the brush roller 12. The brush roller 12 rotates and brushes the belt surface, sweeping and pushing the large dust particles on the belt surface to one side. Then the upper belt surface of the conveyor belt 3 moves to the right and passes under the electrostatic adsorption plate 5. The electrostatic adsorption plate 5 adsorbs the micro dust on the belt surface.

[0087] After the electrostatic adsorption plate 5, which is pressed against the surface of the conveyor belt 3, has been in operation for a certain period of time, the dust on the electrostatic adsorption plate 5 is cleaned by reciprocating push rod 7-4 pushing transmission rod 7-1 outward. In turn, transmission rod 7-1 drives the side baffles 6-3 on both sides of the electrostatic adsorption plate 5 clamped above to open. Then, the rotating mounting bracket 4 drives the electrostatic adsorption plates 5 on the upper and lower sides to exchange positions, so that the clean electrostatic adsorption plate 5 on the upper side is rotated to the lower side and pressed against the surface of the conveyor belt 3 to continue working. The electrostatic adsorption plate 5, which originally had dust adhering to the lower side, is moved to the upper side. Then, the reciprocating push rod 7-4 drives the transmission rod 7-1 to retract, closing the side baffles 6-3 on both sides to clamp the upper electrostatic adsorption plate 5. This, together with the end baffle 6-2, the side baffles 6-3, and the electrostatic adsorption plate 5, forms a box structure with an open upper end. Then, the slide rail stepping system 6-4 drives the brush strip 6-5 to move back and forth, and the brush strip 6-5 sweeps away the dust adhering to the upper surface of the upper electrostatic adsorption plate 5.

[0088] When the reciprocating push rod 7-4 drives the transmission rod 7-1 to rotate, the reciprocating push rod 7-4 drives the lower transmission rod 7-1 to rotate. The lower transmission rod 7-1 drives the drive gear 8-2 on its rotating shaft to rotate. Then, the lower drive gear 8-2 drives the upper drive gear 8-2 to rotate through the reversing gear 8-3. Then, the upper drive gear 8-2 drives the upper transmission rod 7-1 to rotate. The rotation directions of the upper and lower drive gears 8-2 are opposite, and the rotation directions of the upper and lower transmission rods 7-1 are also opposite. When the reciprocating push rod 7-4 drives the transmission rod 7-1 to extend, the ends of the two transmission rods 7-1 on the same side close from the front and rear sides to the middle. Thus, the two transmission rods 7-1 cooperate to push the side baffle 6-3 away from the electrostatic adsorption plate 5, so that the side baffles 6-3 on the left and right sides open. Conversely, when the transmission rod 7-1 retracts, it drives the side baffles 6-3 on both sides to close.

[0089] When the vibrating plate 11 drives the conveyor belt 3 to vibrate up and down, the belt surface of the conveyor belt 3 undergoes tension and relaxation motion. At this time, the torsion spring 13-2 presses down against the rotating frame 13-1. The rotating frame 13-1 presses down against the belt surface of the conveyor belt 3 located between the left and right guide rollers 13-3 through the support roller 13-4. Thus, when the belt surface of the conveyor belt 3 undergoes tension and relaxation motion, it is buffered by the up and down movement of the belt surface pressed against by the support roller 13-4. That is, the vibrating plate 11 pushes the belt surface upward, and the belt surface is tightened. That is, the belt surface is transmitted to the support roller 13-4, which pulls the support roller 13-4 upward. The vibrating plate 11 descends, and the belt surface rebounds. That is, the support roller 13-4 rebounds downward.

[0090] After the upper surface of the conveyor belt 3 passes through the electrostatic adsorption plate 5 to the right, the upper surface of the conveyor belt 3 is clamped and guided by the clamping roller 14, thereby stabilizing the belt surface that is shaking and vibrating due to the dust removal operation.

[0091] The technical advantages achieved by adopting the above technical solution are as follows:

[0092] 1. This device sets up alternating electrostatic adsorption plates 5 so that after a single electrostatic adsorption plate 5 performs dust removal work on the conveyor belt 3 for a moving work cycle, the electrostatic adsorption plate 5 with a large amount of dust adhering to it is lifted up for cleaning and collection of the dust.

[0093] 2. This device is equipped with an end baffle 6-2 and a foldable side baffle for the cleaning part of the electrostatic adsorption plate 5, so that dust and other objects can be intercepted and collected through the box structure formed by the end baffle 6-2 and the side baffle 6-3 when cleaning dust.

[0094] 3. In order to deal with the dirt that may adhere to the conveyor belt 3, this device is equipped with a vibrating plate 11 to beat the belt surface of the conveyor belt 3, and vibrate off the adhered dirt. In addition, a rotating frame 13-1, support roller 13-4, and guide roller 13-3 are also provided for support, so as to buffer and support the belt surface of the conveyor belt 3 when the belt surface vibrates and relaxes.

[0095] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this invention should be included within the protection scope of this invention.
