Description
Technical Field
[0001] This application relates to the field of bread processing and conveying equipment technology, specifically a bread processing and conveying device that is easy to clean. Background Technology
[0002] In the continuous production of baked goods such as bread and pastries, belt conveyors are indispensable logistics equipment, responsible for transporting dough, semi-finished products, or finished products between various processing stations (such as proofing, baking, cooling, and packaging). Since bread raw materials are mostly highly adhesive doughs, and flour dust, syrup splashes, and baking crumbs are generated during processing, these residues are very easy to adhere to the surface of the conveyor belt, rollers, and frame components. If they are not cleaned in time, they will not only breed microorganisms and cause cross-contamination of food, but also leave marks on the surface of subsequent products, affecting the appearance and quality of the finished products, and even causing food safety incidents.
[0003] Currently, the industry mainly uses a fixed scraper installed below the return section of the conveyor belt for cleaning. The scraper blades contact the belt surface to remove loose debris. While this method enables continuous online cleaning, its limitations are obvious. The scraper can only remove loosely adhered particles and is almost ineffective against stubborn residues that adhere to the belt texture due to sugar, oil, or moisture. Some improved equipment uses rotating brush rollers instead of fixed scrapers, using the brushing action of the bristles to remove some of the adhering substances. However, while cleaning the conveyor belt, the brush rollers themselves also pick up a lot of residue, especially fibrous materials like gluten, which easily get tangled at the base of the bristles. If not cleaned in time, these residues will gradually dry and solidify, causing the bristles to harden and deform. This can scratch the conveyor belt during subsequent cleaning, resulting in secondary pollution.
[0004] Therefore, this application provides a bread processing and conveying device that is easy to clean, in order to solve the above-mentioned problems. Summary of the Invention
[0005] To achieve the above objectives, this application provides the following technical solution: a bread processing conveyor device that is easy to clean, including a conveyor body and a cleaning mechanism disposed below the conveyor body. Several support legs are fixedly installed at equal intervals below the crossbeam frame of the conveyor body, and a feeding tray is fixedly installed at one end of the conveyor belt of the conveyor body. The cleaning mechanism includes a cleaning box detachably installed at the lower end of the crossbeam frame. A guide cone box is fixedly installed at the lower end of the cleaning box, and a collection box is detachably installed at the lower end of the guide cone box. Both the cleaning box and the guide cone box are hollow structures. A rotatable brush roller is installed inside the cleaning box. A servo motor is installed on the outside of the cleaning box. A reducer is installed at the output end of the servo motor. The output end of the reducer is connected to the shaft of the brush roller. A cleaning component for cleaning the brush roller is installed inside the cleaning box. A coarse cleaning component is installed on the side of the cleaning box near the discharge tray.
[0006] Preferably, the cleaning assembly includes a fixing seat disposed on the inner wall of the cleaning box, the fixing seat being fixedly connected to the inner wall of the cleaning box by bolts, a cleaning comb being fixedly installed on the cleaning box and horizontally aligned with the brush roller, and two partition plates being symmetrically fixedly installed inside the cleaning box.
[0007] Preferably, the cleaning box has a guide port on the side near the discharge tray, and a fixing frame is fixedly installed on the side of the cleaning comb away from the guide port. The fixing frame is irregularly L-shaped, and a plurality of nozzles are evenly distributed on the fixing frame. The air outlet of the nozzles is aligned with the comb teeth of the cleaning comb. An air guide pipe is provided on the side of the fixing frame away from the cleaning comb, and the air inlet of the plurality of nozzles is connected to the air guide pipe. One end of the air guide pipe is provided with an air inlet.
[0008] Preferably, the coarse cleaning assembly includes a guide cone fixedly installed on the outside of the cleaning box, and a scraper for cleaning the conveyor belt surface is fixedly installed on the inside of the guide cone.
[0009] Preferably, a fixing plate is fixedly installed at both the left and right ends of the top of the cleaning box, a long strip plate is fixedly installed on the inner side of the fixing plate, a plurality of telescopic rods are fixedly installed at equal intervals on the upper end of the long strip plate, a sealing plate is provided at the upper end of the long strip plate and connected to the telescopic end of the telescopic rod, and a spring is sleeved on the outside of the telescopic rod and fixed to the bottom of the sealing plate.
[0010] Preferably, guide blocks are fixedly installed at both ends of the long strip, one side of the guide block is fixedly connected to the inner wall of the cleaning box, and a groove is provided on the sealing plate to fit the guide block.
[0011] Preferably, guide seats are fixedly installed on both sides of the outside of the flow guide cone box, and slots are provided on the guide seats. Arm plates for inserting into the slots are symmetrically fixedly installed on the collection box.
[0012] Preferably, a curtain seat is fixedly installed on the inner wall of the cleaning box near the feed inlet, and an anti-overflow curtain for blocking the feed inlet is fixedly installed on the curtain seat.
[0013] Preferably, reinforcing plates are fixedly installed at both ends of the bottom of the feeding tray, and connecting plates are fixedly installed at the lower ends of the reinforcing plates. Assembly seats are fixedly installed at both ends of the exterior of the cleaning box, and the connecting plates and assembly seats are fixedly connected to the lower end of the crossbeam frame by bolts.
[0014] Preferably, a fixing rod is fixedly installed between the two reinforcing plates, and two sleeves are equidistantly fitted on the fixing rod. An image recognition sensor for capturing the surface of the conveyor belt is fixedly installed on the sleeve.
[0015] This conveying device, by setting up a coarse cleaning component, pre-separates large pieces of debris. The scraper makes elastic contact with the surface of the conveyor belt, which can scrape off large pieces of residue such as dough pieces and bread crumbs before they enter the brush area, preventing large pieces of material from getting tangled in the brush rollers. The funnel-shaped structure of the guide cone hopper concentrates and guides the scraped debris to the guide port. The flexible curtain allows debris to enter the cleaning box in one direction, while preventing dust inside the box from escaping in the opposite direction, reducing air pollution in the workshop.
[0016] This conveying device uses a combination of a fixed plate, a telescopic rod, a spring, a sealing plate, and a guide block. The spring pushes the sealing plate to maintain a constant pressure against the lower surface of the conveyor belt. Even if the conveyor belt bounces or the surface is uneven, it can maintain contact and prevent high-pressure airflow or dust from leaking from the top.
[0017] This conveying device, by setting up a cleaning component, uses the comb teeth of the cleaning comb to insert into the root of the bristles. As the brush roller rotates, it forcibly peels off the gluten and long strips of debris wrapped around the bristles, restoring the bristles to a fluffy state. At the same time, the nozzle is aligned with the comb teeth of the cleaning comb, and compressed air is used to blow away the tiny powder or sugar crystals that are still attached to the root of the bristles after the comb teeth peel off, so as to avoid long-term accumulation and growth of bacteria.

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0021] This embodiment provides a bread processing conveying device that is easy to clean, such as... Figure 1-11 As shown, the conveying device includes a conveyor body 1 and a cleaning mechanism 4 located below the conveyor body 1. Several support legs 2 are fixedly installed at equal intervals below the crossbeam frame of the conveyor body 1, and a discharge tray 3 is fixedly installed at one end of the conveyor belt located on the conveyor body 1. The cleaning mechanism 4 includes a cleaning box 41 that is detachably installed at the lower end of the crossbeam frame. A guide cone box 42 is fixedly installed at the lower end of the cleaning box 41. A collection box 43 is detachably installed at the lower end of the guide cone box 42. Both the cleaning box 41 and the guide cone box 42 are hollow structures. A rotatable brush roller 44 is installed inside the cleaning box 41. A servo motor 47 is installed on the outside of the cleaning box 41. A reducer is installed at the output end of the servo motor 47. The output end of the reducer is connected to the shaft of the brush roller 44. A cleaning component for cleaning the brush roller 44 is installed inside the cleaning box 41. A coarse cleaning component is installed on the side of the cleaning box 41 near the discharge tray 3.
[0022] Furthermore, the conveyor body 1 is supported by legs 2 installed under the crossbeam frame, and a discharge tray 3 is provided at one end of the conveyor belt. The conveyor body 1 is a common conveying equipment in the prior art. The cleaning box 41 is equipped with a brush roller 44, and the brush bristles are in elastic contact with the belt surface. It is driven by a servo motor 47 through a reducer. By integrating the cleaning mechanism 4 under the return section at the tail end of the conveyor, the conveyor belt can be cleaned synchronously during equipment operation without stopping the machine. The coarse cleaning component first scrapes off large loose debris, and then the brush roller 44 brushes off the adhesive residue.
[0023] The cleaning assembly includes a mounting base 45 disposed on the inner wall of the cleaning box 41. The mounting base 45 is fixedly connected to the inner wall of the cleaning box 41 by bolts. A cleaning comb 451, which is horizontally aligned with the brush roller 44, is fixedly installed on the cleaning box 41. Two partition plates 418 are symmetrically fixedly installed inside the cleaning box 41.
[0024] Furthermore, the fixing seat 45 is fixed to the inner wall of the cleaning box 41 by bolts. The cleaning comb 451 is horizontally aligned with the brush roller 44. When the brush roller 44 rotates, the comb teeth of the cleaning comb 451 insert into the bristles and forcibly peel off the residue adhering to the bristles, avoiding secondary pollution caused by residue left on the bristles. It should be noted that the comb teeth of the cleaning comb 451 are customized according to the corresponding brush roller 44. The cross-section of the comb teeth is rectangular, and the spacing of the comb teeth matches the bristle density.
[0025] A guide port 413 is provided on the side of the cleaning box 41 near the unloading tray 3. A fixing frame 452 is fixedly installed on the side of the cleaning comb 451 away from the guide port 413. The fixing frame 452 is irregularly L-shaped. Several nozzles 454 are evenly distributed on the fixing frame 452. The air outlet of the nozzles 454 is aligned with the comb teeth of the cleaning comb 451. An air guide pipe 453 is provided on the side of the fixing frame 452 away from the cleaning comb 451. The air inlet of the several nozzles 454 is connected to the air guide pipe 453. An air inlet is provided at one end of the air guide pipe 453.
[0026] Furthermore, the fixing frame 452 is L-shaped and has a hollow design. The air inlet is connected to an externally set compressed air device. When the brush roller 44 rotates to the cleaning comb 451 position, the nozzle 454 sprays high-pressure gas. The high-pressure gas assists in blowing and thoroughly removes the fine residue deep in the bristles, avoiding long-term accumulation and bacterial growth. The L-shaped fixing frame 452 allows the nozzle 454 to blow obliquely from the side and below, covering the entire bristle area. The blown residue can fall off from the hollow design.
[0027] The coarse cleaning assembly includes a guide cone 46 fixedly installed on the outside of the cleaning box 41, and a scraper 461 for cleaning the surface of the conveyor belt is fixedly installed on the inside of the guide cone 46.
[0028] Furthermore, the scraper 461 serves as the first line of defense and is made of food-grade silicone. It is inclined at an angle of 15-30° to the surface of the conveyor belt, with a smooth blade edge to effectively avoid damaging the belt surface and remove most of the residue in advance, reducing the workload of the brush roller 44. The scraped debris enters the cleaning box 41 through the guide port 413 and finally falls into the collection box 43. The conical structure of the guide cone 46 guides the debris to fall and prevents accumulation.
[0029] Fixed plates 411 are fixedly installed on both the left and right ends of the top of the cleaning box 41. A long strip plate is fixedly installed on the inner side of the fixed plate 411. Several telescopic rods 416 are fixedly installed at equal intervals on the upper end of the long strip plate. A sealing plate 412 connected to the telescopic end of the telescopic rod 416 is provided at the upper end of the long strip plate. A spring 417 fixed to the bottom of the sealing plate 412 is sleeved on the outside of the telescopic rod 416.
[0030] Furthermore, the sealing plate 412 can float up and down, always adhering to the lower surface of the conveyor belt to form a seal and prevent dust from escaping during cleaning. The fixing plate 411 and the cleaning box 41 are integrally formed. The contact surface between the sealing plate 412 and the conveyor belt can be fitted with non-woven fabric strips according to the actual application. At least 8 telescopic rods 416 are provided and distributed at equal intervals along the long strip to ensure that the sealing plate 412 is subjected to uniform force.
[0031] Guide blocks 415 are fixedly installed at both ends of the long strip. One side of the guide block 415 is fixedly connected to the inner wall of the cleaning box 41. A groove is provided on the sealing plate 412 to fit the guide block 415.
[0032] Furthermore, the sealing plate 412 has a groove that fits onto the guide block 415, so that the sealing plate 412 can only move vertically and prevents it from tilting.
[0033] Guide seats 421 are fixedly installed on both sides of the outside of the flow cone box 42. The guide seats 421 are provided with slots. Arm plates 431 for inserting into the slots are symmetrically fixedly installed on the collection box 43.
[0034] Furthermore, the collection box 43 is symmetrically fixed with arm plates 431 on both sides. The arm plates 431 are inserted into the slots to achieve quick assembly and disassembly. The collection box 43 can be installed and disassembled without tools by setting the plug-in structure, which is convenient for dumping waste. The collection box 43 is made of transparent material, which makes it easy to observe the overflow status.
[0035] A curtain seat is fixedly installed on the inner wall of the cleaning box 41 near the feed inlet 413, and an anti-overflow curtain 414 is fixedly installed on the curtain seat to block the feed inlet 413.
[0036] Furthermore, the overflow curtain 414 forms a soft seal, allowing scraped debris to enter the cleaning box 41 in one direction while preventing internal dust from leaking out. The lower end of the curtain hangs freely and contacts the inner wall of the guide cone 46. The curtain is made of silicone material, which is soft and wear-resistant.
[0037] Reinforcing plates 31 are fixedly installed at both ends of the bottom of the feeding tray 3, and connecting plates 5 are fixedly installed at the lower ends of the reinforcing plates 31. Assembly seats are fixedly installed at both ends of the outside of the cleaning box 41. The connecting plates 5 and the assembly seats are fixedly connected to the lower end of the crossbeam frame by bolts.
[0038] Furthermore, the cleaning box 41 has mounting seats at both ends of its exterior. Both the connecting plate 5 and the mounting seats are fixed to the crossbeam frame with bolts, thus achieving a stable installation of the cleaning mechanism 4.
[0039] A fixing rod 6 is fixedly installed between the two reinforcing plates 31. Two sleeves 61 are equidistantly fitted on the fixing rod 6. An image recognition sensor 62 for capturing the surface of the conveyor belt is fixedly installed on the sleeves 61.
[0040] Furthermore, the image recognition sensor 62 monitors the cleanliness of the conveyor belt surface in real time and feeds back to the control system to decide whether to start deep cleaning, such as turning on the brush roller 44 or adjusting the speed. The sleeve 61 can move along the fixed rod 6 to adjust the sensor position. The image recognition sensor 62 adopts an industrial-grade CMOS sensor and can be equipped with a transparent protective cover according to the application environment to prevent dust from contaminating the lens. At the same time, the sensor signal is connected to the PLC to realize automated control.
[0041] In use, when the conveyor belt reaches the return section at the end, it first passes through the scraper 461 inside the guide cone 46. The scraper 461 scrapes off the loose, large pieces of bread crumbs from the surface. The crumbs enter the cleaning box 41 through the guide port 413 and fall into the collection box 43 below. The overflow curtain 414 prevents dust from escaping. After coarse cleaning, the conveyor belt continues to move to the brush roller 44. The servo motor 47 drives the brush roller 44 to rotate at high speed. The rotation direction of the brush roller 44 is opposite to that of the conveyor belt. The bristles penetrate deep into the texture of the belt surface to brush off the highly adhesive residue. The brushed residue falls into the guide cone 42 under gravity and finally enters the collection box 43. The brush roller 44 rotates through... During the process, the bristles pass through the cleaning comb 451, where the comb teeth forcibly peel off the residue adhering to the bristles. At the same time, compressed air is introduced through the air duct 453, and high-pressure gas is sprayed from the nozzle 454 onto the comb teeth to blow off the tiny dust particles that have been peeled off but not yet fallen off, keeping the bristles clean. The floating sealing plate 412 on the top of the cleaning box 41 always adheres to the lower surface of the conveyor belt under the action of the spring 417 to prevent dust from splashing. The collection box 43 is connected to the guide seat 421 through the arm plate 431 for easy disassembly and cleaning. The image recognition sensor 62 captures the image of the conveyor belt surface in real time, detects the cleaning effect, and can automatically adjust the speed of the brush roller 44 or start or stop it according to the residue situation.
[0042] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
