Description

Technical Field

[0001] The present invention relates to the technical field of conveying equipment, in particular to a layered mesh belt conveyor. Background Art

[0002] Mesh belt conveyor is a material handling machine that continuously transports materials along a certain route. It is also called continuous conveyor. It can be divided into mesh belt type and mesh chain type. The conveyor can perform horizontal, inclined and vertical transportation, and can also complete several process operations simultaneously during the transportation process.

[0003] Existing mesh belt conveyors are used as carrying and conveying equipment when processing food. Food is placed on the conveyor belt and conveyed as the conveyor belt moves. However, for foods that need to be coated with batter or are loose, food residues will adhere to the conveyor belt. As the conveyor belt circulates, more and more residues will adhere to subsequent foods, reducing the quality of food processing. To this end, we propose a layered mesh belt conveyor to solve the above problems. Summary of the Invention

[0004] The purpose of the present invention is to solve the problems existing in the prior art and to propose a layered mesh belt conveyor.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A layered mesh belt conveyor comprises two end plates, two drive shafts are rotatably mounted between the end plates, a chain belt assembly is sleeved on the outer sides of the two drive shafts, the drive shaft comprises a central shaft, a belt is sleeved on the outer sides of the central shaft, toothed discs with a diameter larger than the drive shaft are mounted at the front and rear ends of the drive shaft, the chain belt assembly comprises a plurality of equally spaced support rods, hinged chains are mounted between the support rods, the support rods are connected in series to form a ring through the hinged chains, the front and rear ends of the support rods pass through the hinged chains to form overlapping portions, the overlapping portions are in pressure contact with the circumferential side walls of the toothed discs, and a collecting assembly is mounted on the lower part of the end plates between the belts and the chain belt assembly;

[0007] When transporting food, the food is placed on top of the chain belt assembly. As the drive shaft rotates, the annular chain belt assembly can be driven to rotate through the toothed disc, thereby pushing the food from right to left. On the inner side of the chain belt assembly, the belt is driven to rotate by the rotation of the central axis, which can catch the food residues falling from above, and as it rotates, the residues are adhered and driven to the collection assembly position below to achieve the collection of the residues.

[0008] Preferably, the inner wall of the belt is provided with two front and rear racks, and the side wall of the central shaft is provided with a through tooth groove engaged with the racks;

[0009] The rack setting can drive the belt to rotate stably and prevent slipping by meshing the through-tooth grooves and the rack when the middle shaft rotates. The middle shaft adopts a hollow structure, and the residue in the through-tooth grooves can be pushed into the middle hole of the middle shaft to prevent the through-tooth grooves from being filled with residue, thereby ensuring stable meshing.

[0010] Preferably, a support piece is sleeved and installed on the middle part of the outer side of the support rod, and the circumferential side wall of the support rod is provided with equidistantly arranged adapter ring grooves, and the support pieces are embedded and rotatably installed in the adapter ring grooves one by one;

[0011] The support plate is set up to reduce the contact area with the food, suspend the food, and reduce the possibility of food adhering to the support plate and the support rod. The support plate is positioned and rotatably installed to prevent forward and backward movement and ensure stable support.

[0012] Preferably, the circumferential side wall of the toothed disc is provided with a plurality of meshing grooves in an annular array, and the overlapping portion is meshed and overlapped with the circumferential side wall of the toothed disc through the meshing grooves;

[0013] The circumferential side wall of the toothed disc is provided with a plurality of engagement grooves in an annular array, which can engage with the overlapping portion to ensure that when the toothed disc rotates, the overlapping portion can be clamped and pushed to achieve stable transmission and prevent slipping.

[0014] Preferably, the collecting shell includes an upwardly opening, and a scraper is installed at the opening of the collecting shell, and the top end of the scraper is in sliding contact with the bottom end of the belt;

[0015] The collection shell has a collection port that opens upward, and the top of the scraper slides against the bottom of the belt to hang down the residue at the bottom of the belt. The collection shell is connected to an external electrostatic generator through a wire, which can make the belt passing through have static electricity, thereby ensuring that when the belt rotates, the residue will move with the belt to the collection shell position, and the residue at the scraper position will fall under the action of its own weight as it gathers.

[0016] Preferably, a plurality of scrapers are provided, the scrapers are arranged side by side, and the top ends of the scrapers are inclined at equal angles toward the direction of the belt;

[0017] There are multiple scrapers, which are arranged side by side and can scrape off the residue at the bottom of the belt in multiple times. The top of the scraper is inclined at an equal angle to the direction of the belt, which can ensure that the side wall of the top of the scraper and the side wall of the bottom of the belt form an acute angle, making it easier to scrape off the residue on the belt surface.

[0018] Preferably, a plurality of horizontally arranged pressure rollers are rotatably mounted in the middle of the end plate, the lower portion of the belt is press-fitted between the circumferential side wall of the pressure roller and the top side wall of the scraper, and an annular groove cooperating with the rack is provided at the edge of the pressure roller;

[0019] The horizontally arranged pressure rollers can press the belt down and make it in close contact with the side wall of the scraper top to ensure thorough scraping. The annular groove ensures the smooth passage of the rack, preventing the belt from bulging excessively at the rack position and ensuring the flatness of the belt.

[0020] Preferably, the collecting assembly comprises a collecting shell, a friction plate is mounted on the bottom end of the collecting shell, a slot is formed on the bottom end of the friction plate for the support sheet to pass through, and the front and rear inner walls of the slot are in sliding contact with the front and rear outer walls of the support sheet;

[0021] The collection shell can collect residues, and the friction plate under the collection shell can rub against the support sheet when the support sheet passes through, and the friction force drives the support sheet to rotate, so that the outer walls around the support sheet can contact and slide with the front and rear inner walls of the groove, thereby achieving stable cleaning of the support sheet.

[0022] Preferably, the support piece is in the shape of an equilateral triangle, and the depth of the slot is greater than the distance from the farthest point of the support piece to the outer wall of the support rod;

[0023] The support piece adopts the shape of an equilateral triangle, which can contact the food at the end corner to make the contact area smaller, further reducing food adhesion, and the depth of the groove is greater than the distance from the farthest point of the support piece to the outer wall of the support rod, which can ensure that the outer wall of the support piece can be completely immersed in the groove during rotation, ensuring thorough cleaning.

[0024] Preferably, a guide roller cooperating with the hinge chain is installed at the lower part of the collection shell, and limiting protrusions are installed at the front and rear ends of the guide roller for sliding contact with the front and rear side walls of the hinge chain. Two supporting rollers are rotatably installed at the lower part of the end plate, and the supporting rollers roll and abut against the bottom end of the hinge chain.

[0025] The setting of the guide roller can press the articulated chain downward, leaving room for quick installation of the collection shell, and two support rollers are rotatably installed at the lower part of the end plate to support the articulated chain and ensure the smooth passage of the chain belt assembly.

[0026] Compared with the existing technology, the advantages of this layered mesh belt conveyor are:

[0027] 1. Through the setting of the chain belt assembly, cylindrical support rods are arranged at equal distances and connected in series into a ring through a hinged chain to form a chain belt for material transportation. There are equidistant gaps between the support rods, which allow the residues that fall off the food to fall and be collected by the inner component. The support rods are equipped with support plates that rotate on the outside to lift the food, reducing the contact area between the rods and the food. As the rods rotate, the collection component scrapes away the remaining food residues on the clean surface.

[0028] 2. Through the setting of the belt, the endless belt can carry the food residues falling from above, and the outer surface of the belt is treated with electrostatics. The food residues can be brought to the collection component position through electrostatic adsorption, and then dropped into the collection shell by the scraper, so that the belt surface is kept clean. The scraper is connected to the external electrostatic generator through a wire, and as a conductor, it can replenish the static electricity on the belt surface when the belt circulates.

[0029] 3. Through the setting of the collection component, a collection shell with an upward opening is set under the belt to collect the debris scraped by the scraper, which can be discharged from the slag discharge port at the front end. The lower end of the collection shell is provided with a support roller and a guide roller, which can reverse the lower part of the chain belt component to leave space for the installation of the collection component. The bottom end of the collection shell is provided with a friction plate, and the bottom end of the friction plate is provided with equidistantly arranged grooves, so that when the support sheet passes through, the support sheet can roll through the groove for cleaning.
