Description

Technical Field

[0001] This utility model relates to the field of chain link processing technology, and in particular to a feeding mechanism for hot processing of chain links. Background Technology

[0002] Existing transmission chains are generally composed of inner and outer chain links. Before producing transmission chains, the scattered chain links need to be sorted and strung together. Traditionally, the sorting and strung-together chain links are done manually by workers. The entire chain sorting process is labor-intensive and inefficient, and cannot meet production needs.

[0003] Existing chain hot processing methods typically involve placing the chain links on a feeding track and then transporting them directly to a heating furnace for hot processing. Often, the chain links will stack on the feeding track, requiring the heating furnace to consume more energy to process them. However, direct high-temperature heating of the chain links can cause a large temperature difference between the inner and outer layers, leading to uneven heating and an increased risk of chain deformation or cracking. Utility Model Content

[0004] To address the above problems, the present invention aims to provide a feeding mechanism for hot processing of chain links.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a feeding mechanism for hot processing of chain links, including a mounting frame, a feeding belt and a drive motor. The chain links are fed through the feeding belt, which is mounted on the mounting frame. The drive motor provides kinetic energy for the operation of the feeding belt. The mounting frame is characterized by having a heat insulation cover and a feeding bin. The feeding bin is fixedly mounted on the heat insulation cover and has a feeding port for conveying chain links. A heating mechanism is fixedly mounted inside the heat insulation cover. When the chain links pass through the feeding port and are fed through the feeding belt, the heating mechanism preheats the chain links.

[0006] A further preferred embodiment of this utility model is: the heat insulation cover is provided with a shell and a detachable upper cover on the shell, and the heating mechanism is disposed inside the shell.

[0007] A further preferred embodiment of this utility model is: the heating mechanism includes an assembly frame, an assembly shaft, and an electric heating element, wherein the electric heating element and the assembly frame are fixedly mounted on the housing via the assembly shaft.

[0008] A further preferred embodiment of this utility model is: the feeding belt is provided with a baffle to prevent the chain from sliding down.

[0009] A further preferred embodiment of this utility model is that the two sides of the feeding belt are provided with wavy sidewalls.

[0010] A further preferred embodiment of this utility model is: a guide plate and a scraper are provided inside the feed hopper, and the guide plate is used to prevent the chain links from getting stuck on the edge of the feed belt.

[0011] A further preferred embodiment of this utility model is that the scraper is made of high-temperature resistant soft rubber.

[0012] A further preferred embodiment of this utility model is that the scraper abuts against the surface of the feeding belt to prevent the chain from slipping off into the feeding belt.

[0025] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0026] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0027] This embodiment mainly describes a feeding mechanism for hot processing of chain links, as detailed below:

[0028] like Figure 1 As shown, a feeding mechanism for hot processing of chain links includes a mounting frame 2, a feeding belt 21, and a drive motor 3. The drive motor 3 provides kinetic energy for the operation of the feeding belt 21. Specifically, the drive motor 3 is located on one side of the mounting frame 2, and an output shaft 12 is provided on the drive motor 3. Two drive rollers 13 are provided on the mounting frame 2, and the two drive rollers 13 are respectively located at both ends of the mounting frame 2. One end of the output shaft 12 is located inside the drive motor 3, and the other end is inserted into the drive roller 13. The drive motor 3 drives the drive roller 13 to rotate synchronously through the output shaft 12. The inner side of the feeding belt 21 abuts against the two drive rollers 13 and rotates synchronously with the drive rollers 13 to drive the chain links to complete the feeding operation.

[0029] like Figure 4 As shown, a tensioning wheel 17 is provided in the middle of the mounting frame 2. The tensioning wheel 17 abuts against the inner side of the feeding belt 21. When the feeding belt 21 runs under the action of the drive roller 13, the tensioning wheel 17 rotates synchronously with the feeding belt 21 to automatically adjust the tension of the feeding belt 21 and prevent the feeding belt 21 from slipping or derailing during the feeding process and causing an accident.

[0030] like Figure 1As shown, the mounting frame 2 is equipped with an insulation cover 4 and a feeding bin 6. The feeding bin 6 is fixedly mounted on the insulation cover 4 by welding. The surface of the feeding bin 6 has a protruding inlet 7. The chain pieces to be heat-treated are conveyed into the feeding bin 6 through the inlet 7. The size and shape of the inlet 7 can be designed and modified according to the size and shape of the chain pieces to ensure that the chain pieces can smoothly enter the feeding bin 6 and slide onto the feeding belt 21.

[0031] The mounting frame 2 is provided with a support frame 1 below it. The mounting frame 2 is fixedly mounted on the support frame 1, which facilitates the loading of chain links from low to high.

[0032] like Figure 8 , Figure 9 As shown, the feed hopper 6 is equipped with guide plates 18 and scrapers 25. There are two guide plates 18, which are symmetrically arranged on the inner walls of the feed hopper 6 at a certain angle. When the number of chain pieces conveyed at the feed inlet 7 is large, the conveyed chain pieces slide down onto the feed belt 21 at a suitable angle and direction via the guide plates 18, preventing the chain pieces from getting stuck on the edge of the feed belt 21 and causing damage to the feed belt 21.

[0033] The scraper 25 is made of high-temperature resistant soft rubber. The scraper 25 abuts against the surface of the feed belt 21 to further prevent the chain from slipping off the feed belt 21 during operation.

[0034] When the chain links fall from the feed inlet 7 into the feed bin 6 and slide toward the feed belt 21, the guide plate 18 plays a preliminary guiding role, while the scraper 25 constrains the chain links during the operation of the feed belt 21. The scraper 25 can be installed in a suitable position in the feed bin 6 by means of adhesive bonding, slot fixing or bolt fastening. Preferably, the scraper 25 is set in the feed bin 6 by bolt fastening.

[0035] like Figure 2 As shown, the heat insulation cover 4 is fixed on the mounting frame 2 by screws, and the heat insulation cover 4 covers part of the conveyor chain of the feeding belt 21. The heat insulation cover 4 is provided with a shell 8 and a detachable upper cover 9 on the shell 8. The shell 8 is provided with two vertical plates 11, which are symmetrically arranged on both sides of the shell 8.

[0036] The upper cover 9 can be connected to the vertical plate 11 by a suitable connection method, such as bolt connection, snap-fit, etc. Preferably, the upper cover 9 is connected to the vertical plate 11 by bolt connection. The upper cover 9 is provided with a handle 5. When the feeding mechanism malfunctions after a long period of time, the user can use tools to loosen the bolts fixing the upper cover 9 and open the corresponding upper cover 9 through the handle 5 to repair or replace the damaged parts without disassembling the whole, thus saving costs.

[0037] like Figure 5 , Figure 7 As shown, a heating mechanism is provided inside the housing 8. Specifically, the heating mechanism includes an assembly frame 14, an assembly shaft 15, and several heating elements 16. There are two assembly frames 14, which are arranged side by side. Each heating element 16 is fixed between the two assembly frames 14 by screws. Each heating element 16 is fixedly connected to the assembly frame 14 by the assembly shaft 15.

[0038] like Figure 2 As shown, the housing 8 is provided with two horizontal plates 10, which are symmetrically arranged. The assembly frame 14 is fixedly installed between the two horizontal plates 10 by welding.

[0039] like Figure 7 As shown, the heating element 16 includes a lead wire 22, a reflector 23, and a heating element 24. The lead wire 22 is connected to a power source to provide energy to the heating element 24. The reflector 23 is arranged around the heating element 24 to facilitate the concentration of heat from a single heating element 24, reduce heat loss, and improve heating efficiency.

[0040] like Figure 5 As shown, the feed belt 21 is provided with baffles 20 and side guards 19. The baffles 20 protrude from the feed belt 21 and are fixedly mounted on the feed belt 21 by welding. When the chain pieces are conveyed to the feed belt 21 through the feed inlet 7, some of the chain pieces will abut against the baffles 20 to effectively prevent the chain pieces from sliding down. The baffles 20 are arranged at intervals along the running direction of the feed belt 21, and their height is designed according to the thickness and shape of the chain pieces to ensure that they can effectively prevent the chain pieces from sliding down when sliding on the feed belt 21.

[0041] like Figure 6 As shown, the guard edges 19 are provided on both sides of the feeding belt 21, and the guard edges 19 are wavy, which not only increases the strength of the guard edges 19 and prevents them from being deformed due to the collision of the chain links during the feeding process, but also better adapts to the movement of the chain links on the feeding belt 21, avoiding damage to the chain links due to the collision of the hard guard edges 19. The guard edges 19 can be integrally formed with the feeding belt 21, for example, by injection molding, or fixed to the edge of the feeding belt 21 by welding. Preferably, the guard edges 19 are fixed on both sides of the feeding belt 21 by welding.

[0042] During the hot processing of chain links, the chain links are first placed at the inlet 7 of the feed bin 6. The chain links enter the feed bin 6 through the inlet 7. Inside the feed bin 6, the guide plate 18 guides the chain links to slowly slide down to the feed belt 21. At this time, the scraper 25 closely abuts against the surface of the feed belt 21 to prevent the chain links from sliding out of the feed belt 21.

[0043] The drive motor 3 starts, driving the feeding belt 21 to run. The baffles 20 and the wavy side guards 19 on both sides of the feeding belt 21 ensure that the chain moves smoothly with the feeding belt 21. During the process of the chain being transported by the feeding belt 21, the heating element 16 of the heating mechanism inside the heat insulation cover 4 starts to work, heating the air inside the heat insulation cover 4, and then preheating the chain on the feeding belt 21. When the chain passes the feeding belt 21 and approaches the processing area, the preheating process is completed, preparing for the subsequent hot processing.
