Description

Technical Field

[0001] This utility model relates to the field of curing oven technology, and in particular to a feeding device for a three-dimensional drying and curing oven. Background Technology

[0002] As is widely known, more and more industrial products, daily consumer products such as electronic products, mobile phones, and agricultural products now require heating, drying, and curing.

[0003] Currently, the heating furnace equipment used for drying and curing has the following problems: In practical applications, existing continuous drying and curing furnaces are basically transported by dynamic transmission. In order to improve efficiency, materials are often designed to be fed in two or more rows, and the materials are often fed intermittently. In order to facilitate the continuous entry and exit of materials in the drying and curing furnace, the two ends of the furnace body are basically designed to be open. If the materials are required to be placed in two or more rows, the size of the furnace inlet and outlet will be larger. Such a structure will inevitably cause the heat inside the furnace to overflow and increase the temperature of the working environment in the process of spreading to the surrounding area, thereby causing energy waste and certain thermal pollution.

[0004] Furthermore, the open ends of existing heating furnaces make it difficult to maintain a stable range of heat energy within the furnace in practical applications. This means that the set temperature of the drying and curing furnace differs significantly from the actual temperature radiated onto the product to be dried and cured inside the furnace. Additionally, the temperature inside the furnace is also affected by the outside air temperature, resulting in large temperature fluctuations. All these factors affect the stability of the drying and curing process, making it difficult to fully meet the requirements of the production process. Therefore, there is an urgent need for a high-efficiency feeding device for heating furnaces that can facilitate the smooth and continuous entry of materials into the drying and curing furnace while preventing excessive heat loss from the furnace. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a feeding device for a three-dimensional drying and curing oven. It can not only effectively reduce the energy waste and thermal pollution problems existing in the feeding of existing heating drying ovens, but also improve production efficiency by stabilizing the temperature environment inside the oven, thereby improving product quality, meeting production cycle, and ultimately effectively reducing the production cost of the curing oven user. It can effectively solve the problems in the background technology.

[0006] To achieve the aforementioned objective, this utility model adopts the following technical solution:

[0007] A feeding device for a three-dimensional drying and curing oven includes a drying and curing oven body. A conveyor is installed at the front end of the feeding inlet of the drying and curing oven body.

A pushing cylinder assembly and a blocking cylinder component are respectively installed on the fixed bracket. An oven door mechanism is installed at the front end of the feeding inlet of the drying and curing oven body corresponding to the position of the oven door.

[0008] Furthermore, the pusher cylinder assembly consists of a linear bearing with a guide rod, a pusher connecting plate connected to the rodless cylinder, and a secondary cylinder with a horizontal orientation corresponding to the feed inlet on the bottom surface of the pusher head. The end of the guide rod is fixedly connected to the fixed bracket, the linear bearing is mounted on the guide rod, the rodless cylinder is installed inside the fixed bracket near the left side, and the pusher connecting plate is fixed to the movable part of the rodless cylinder.

[0009] Furthermore, the material blocking cylinder component consists of a material blocking device cylinder perpendicular to the conveyor, a baffle plate, and a second linear bearing. The baffle plate is fixed to the telescopic end of the material blocking device cylinder, and the second linear bearing is mounted on a fixed bracket and connected to the baffle plate.

[0010] Furthermore, the cylinder-driven furnace door consists of a cylinder and a furnace door plate, and is designed to be installed above the furnace door.

[0011] Furthermore, the furnace door mechanism consists of a cylinder and a furnace door plate, with the furnace door plate fixed to the telescopic end of the cylinder, and the cylinder installed at the front end of the drying and curing furnace body.

Detailed Implementation

[0016] The present invention will be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention.

[0017] Please see Figure 1-2 This embodiment provides a technical solution: a feeding device for a three-dimensional drying and curing oven, including a drying and curing oven body 1, a conveyor 13 installed at the front end of the feeding port of the drying and curing oven body 1, a fixed bracket 2 provided at the front end of the drying and curing oven body 1 corresponding to the position of the oven door, a pushing cylinder group and a blocking cylinder component respectively installed on the fixed bracket 2, and an oven door mechanism 9 installed at the front end of the feeding port of the drying and curing oven body 1 corresponding to the position of the oven door 8.

[0018] The pusher cylinder assembly consists of a linear bearing 6 with a guide rod 5, a pusher connecting plate 4 connected to the rodless cylinder 3, and a secondary cylinder 7 with the bottom surface of the pusher head corresponding to the feed inlet. The end of the guide rod 5 is fixedly connected to the fixed bracket 2. The linear bearing 6 is mounted on the guide rod 5. The rodless cylinder 3 is installed inside the fixed bracket 2 near the left side. The pusher connecting plate 4 is fixed on the movable part of the rodless cylinder 3. The baffle cylinder assembly consists of a baffle device cylinder 10 perpendicular to the conveyor 13, a baffle plate 11, and a second linear bearing 12. The baffle plate 11 is fixed to the telescopic end of the baffle device cylinder 10. The second linear bearing 12 is mounted on the fixed bracket 2 and connected to the baffle plate 11.

[0019] After the first workpiece tray is placed on conveyor 13, conveyor 13 starts and conveys the workpiece tray towards the feeding device. According to the instructions of the CNC device, the blocking device in the feeding device of the first feeding furnace door drops to block the workpiece tray. At this time, the furnace door mechanism 9 opens the furnace door. In the next step, the rodless cylinder 3 in the pushing device starts to push the workpiece tray into the drying and curing furnace body 1. In the next step, the secondary cylinder 7 in the pushing device starts to push the workpiece tray into the furnace. The rodless cylinder 3 retracts, the secondary cylinder 7 retracts, and the furnace door mechanism 9 closes the furnace door. The first workpiece tray is now in the furnace. The first workpiece tray is then fed into the furnace. Next, the second workpiece tray, transported by the conveyor 13, passes smoothly through the first drying and curing oven's feeding device because the first feeding device's blocking device is now raised. It then reaches the second feeding device, where the blocking device is lowered, preventing it from entering. At this point, the second furnace door device 9 opens the furnace door. In the next step, the rodless cylinder 3 in the feeding device is activated to push the workpiece tray into the drying and curing oven body 1. Then, the secondary cylinder 7 in the next feeding device is activated to push the workpiece tray into the oven. The rodless cylinder 3 retracts, the secondary cylinder 7 retracts, and the oven door mechanism 9 closes the oven door. Thus, the second workpiece tray has completed its feeding process. Similarly, the third, fourth, and nth workpiece trays are fed into the drying and curing oven body 1 according to this process. Its overall structure is compact, occupies a small area, and is easy to manufacture and operate. Its structure can be connected to the oven door located at the feed inlet. It not only effectively reduces heat overflow from the oven when the trays enter and exit the curing oven, but also meets the continuous feeding requirements of assembly line production. Compared with the feeding devices of existing heating and drying ovens, it not only effectively reduces energy waste and thermal pollution problems during feeding, but also improves production efficiency by stabilizing the oven temperature environment, thereby improving product quality, meeting production cycle requirements, and ultimately effectively reducing the production costs for the curing oven user.

[0020] The furnace door mechanism 9 consists of a cylinder and a furnace door plate. The furnace door plate is fixed to the telescopic end of the cylinder. The cylinder is installed at the front end of the drying and curing furnace body 1. The telescopic end of the cylinder drives the furnace door plate to move up and down, thereby opening or closing the furnace door 8, ensuring the rationality of the design.

[0021] The working principle of the feeding device for a three-dimensional drying and curing oven provided by this utility model is as follows: When the first workpiece tray is placed on the conveyor 13, the conveyor 13 starts and conveys the workpiece tray towards the feeding device. According to the instructions of the CNC device, the baffle device in the feeding device of the first feeding oven door drops to block the workpiece tray. At this time, the oven door mechanism 9 opens the oven door. In the next step, the rodless cylinder 3 in the pushing device starts to push the workpiece tray into the oven body 1 of the drying and curing oven. In the next step, the secondary cylinder 7 in the pushing device starts to push the workpiece tray into the oven. The rodless cylinder 3 retracts, the secondary cylinder 7 retracts, and the oven door mechanism 9 closes the oven door. At this time, the baffle device cylinder 10 lifts to allow the workpiece tray to pass through. Thus, the first workpiece tray has completed the oven feeding process. Next, the conveyor 13 conveys... The second workpiece tray, having passed smoothly through the feeding device of the first drying and curing oven since the baffle of the first feeding device has been raised, arrives at the second feeding device. Since the baffle of the second feeding device has fallen, the workpiece tray is blocked under it. At this point, the second furnace door device 9 opens the furnace door. Next, the rodless cylinder 3 in the pushing device starts, pushing the workpiece tray into the drying and curing oven body 1. Then, the secondary cylinder 7 in the pushing device starts, pushing the workpiece tray into the furnace. The rodless cylinder 3 retracts, the secondary cylinder 7 retracts, and the furnace door mechanism 9 closes the furnace door. Thus, the second workpiece tray completes its entry into the furnace. Similarly, the third, fourth, and nth workpiece trays are fed into the drying and curing oven body 1 according to this process.
