Description

Technical Field

[0001] The invention relates to the technical field of infrared ovens, and in particular to an infrared oven and a working method thereof. Background Art

[0002] Infrared heating is based on the principle of solar radiation. It is composed of electric heating tubes, quartz tubes and carbon fiber tubes. When powered on, it generates medium-wave infrared rays (wavelength between 1mm and 760nm) to directly radiate and heat objects, thereby achieving heating and baking.

[0003] In the current manufacturing industry, many product parts need to be heated and baked after production. For example, after the parts are painted, they are baked to improve the air-drying efficiency of the paint layer on the surface of the product parts. Some parts also need to be dried quickly after cleaning. The current method of baking and drying them is generally to use a drying oven.

[0004] The existing Chinese patent document CN208645789U discloses a quartz stone curing tunnel oven. It can be seen from the scheme that common ovens generally have a belt conveyor for transmitting the objects to be baked and an oven body above the conveyor belt. The objects move on the belt conveyor and pass through the oven body, so that the objects after being transmitted can reach the required quality of heating, baking and drying. In order to ensure that the objects can be dried evenly and avoid the problem that some parts are not baked and dried, the conveyor belt usually runs very slowly, which results in the personnel needing to wait for the belt conveyor to slowly push when placing the objects to be dried. It takes a long time to place the objects. Usually, after placing the objects, it is necessary to go to the output end of the belt conveyor to collect the materials, which takes up a long time of manpower. For this reason, the present invention proposes an infrared oven and a working method thereof. Summary of the invention

[0053] Embodiment 1

[0054] See also Figure 1-Figure 4, an infrared oven shown in the figure includes an infrared oven body 1, a plurality of placing frames 2 and two sets of placing mechanisms 3 for stacking the placing frames 2, the placing frames 2 are used to place items to be baked, and both sides of the placing frames 2 are fixed with pull plates 4; a loading member 5, used to push the placing frames 2 into the placing mechanisms 3, the loading member 5 is installed under the placing mechanisms 3, and a moving component 6 is installed at the bottom of the placing mechanisms 3, and the moving component 6 is used to drive the placing mechanisms 3 to move at one end of the infrared oven body 1;

[0055] In this solution, a placing mechanism 3 is designed at the feeding end of the infrared oven, which cooperates with the charging member 5 to realize automatic loading and pre-storage of a certain amount of materials to be baked, and then the placing mechanism 3 is moved to the top of the conveyor belt of the infrared oven by the moving component 6. Figure 1 and Figure 2 As shown, the stacked placement frames 2 can be sequentially dropped onto the conveyor belt in the oven, thereby automatically placing the materials to be baked without the need for personnel to load the materials, thereby freeing up manpower;

[0056] refer to Figure 5 , Figure 7-Figure 9 , two groups of placing mechanisms 3 are placed opposite to each other, and a plurality of placing frames 2 are located between the two groups of placing mechanisms 3, the placing mechanism 3 includes two supporting rods 7, both of which are provided with moving grooves 8, and a stabilizing rod 9 is fixed in the moving grooves 8, an adjusting plate 10 is slidably sleeved on the outer side of the stabilizing rod 9, and a pushing spring 11 for pushing the adjusting plate 10 upward is sleeved on the top of the stabilizing rod 9, a plurality of limiting rings 12 are equidistantly fixed on the outer side of the supporting rod 7, and a plurality of placing pieces 13 for clamping the placing frames 2 are slidably sleeved on the outer side of the supporting rod 7, and the plurality of placing pieces 13 are located between the plurality of limiting rings 12, a connecting plate 14 is fixed at the bottom of the two adjusting plates 10, and a linkage piece 15 adapted to the charging piece 5 is fixed to the outer side of the bottom of the supporting rod 7 away from the infrared oven body 1, and the linkage piece 15 is used to drive the connecting plate 14 to move up and down;

[0057] Among them, reference Fig.10 and Fig.11The placing member 13 includes a collar 16 which is slidably sleeved on the outer side of the supporting rod 7, the collar 16 is located between the plurality of limiting rings 12, a U-shaped frame 17 is fixed on the outer side of the collar 16, and a placing plate 18 is rotatably installed in the U-shaped frame 17 through a rotating shaft, a resisting strip 19 which abuts against the outer side of the placing plate 18 is fixed on the top of the U-shaped frame 17, a baffle 20 is fixed on the outer side of the collar 16, and a certain angle is formed between the baffle 20 and the placing plate 18, a track opening 21 is opened at the position of the collar 16 corresponding to the adjusting plate 10, and an adjusting rod 22 which is slidably plugged into the track opening 21 is fixed on the outer side of the adjusting plate 10, wherein, in order to facilitate the abutment with the placing plate 18, a chamfer is opened at the bottom of the outer end of the placing plate 18, and the track opening 21 is composed of two vertical openings and an arc-shaped opening, and the two ends of the arc-shaped opening are respectively connected with the two vertical openings, so that when the adjusting rod 22 moves along the track opening 21, it will drive the collar 16 to rotate a certain angle;

[0058] At the same time, reference Figure 6 The loading member 5 includes an electric push rod 35 fixed in front of the feeding end of the infrared oven body 1, a support plate 36 is fixed to the output end of the electric push rod 35, and guide plates 37 are fixed on both sides of the support plate 36, and a limit plate 38 is fixed on one side of the support plate 36 close to the infrared oven body 1;

[0059] Specifically, the guide plate 37 on the support plate 36 facilitates the placement of the placement frame 2. At the same time, the design of the limit plate 38 cooperates with the two guide plates 37 to position and support the placement frame 2, which is convenient for the subsequent neat stacking and placement of the placement frame 2.

[0060] The principle of using four placing pieces 13 on the same plane to position and place the placing frame 2 is as follows: first, the placing frame 2 is placed on the supporting plate 36 at the top of the electric push rod 35, and then the placing frame 2 is pushed upward by the lifting of the electric push rod 35, so that the two ends of the placing frame 2 first contact the outer bottom ends of the four placing plates 18, and then the placing plates 18 are rotated along the rotating shaft by external force, so that the outer edge of the placing frame 2 passes through the four placing plates 18, and as the electric push rod 35 moves downward, the outer edge of the placing frame 2 moves downward and abuts against the outer top ends of the four placing plates 18, and under the action of the abutting bar 19, one end of it can be abutted, so as to realize the placing of the placing frame 2, and then similarly, the new placing frame 2 will also rise from the bottom, and at the same time, the upper placing frame 2 will continue to be pushed upward, so that it can be placed in contact with the four placing pieces 13 of the upper layer, so as to realize the stacking and placing of multiple placing frames 2 in sequence from top to bottom;

[0061] The principle of sequentially dropping the multiple neatly stacked placement frames 2 is as follows: by moving the adjustment plate 10 downward, the multiple outer adjustment rods 22 are synchronously moved downward, so that they move downward along the track opening 21, thereby driving the ring 16 to rotate, so that the placement plate 18 is separated from the outer edge of the placement frame 2, and then the baffle plate 20 replaces the previous position of the placement plate 18. When the placement plate 18 rotates to separate from the outer edge of the placement frame 2, the placement frame 2 will move downward with its own gravity, and when the baffle plate 20 rotates to replace the position of the placement plate 18, the downward-moving placement frame 2 will be resisted again, so that The lowermost placing frame 2 will fall onto the conveyor belt of the infrared oven, and then the adjusting plate 10 will move up under the action of the pushing spring 11, which will cause the sleeve ring 16 to rotate and reset, and the baffle 20 will also be separated from the outer edge of the placing frame 2 and the placing plate 18 will be reset. At this time, the placing frame 2 will be separated from the baffle 20 and will be against the placing plate 18. Through the synchronous reciprocating rotation of the sleeve rings 16 on multiple planes, the stacked multiple placing frames 2 can be moved down in sequence, and the lowermost placing frame 2 can be dropped onto the conveyor belt each time, thereby realizing automatic unloading operation.

[0062] Specifically, refer to Figure 5 and Figure 7 The moving assembly 6 includes two U-shaped frames 39, in which screw rods 40 are rotatably installed through bearings, and two moving seats 41 are threadedly sleeved on the outer sides of the screw rods 40, and the two moving seats 41 are respectively fixed to the bottoms of the two support rods 7 in each group of the placement mechanism 3, and the outer ends of the two screw rods 40 are fixed with rotating gears 42, and the outer sides of the two rotating gears 42 are meshed with toothed belts 43, and the outer end of one of the U-shaped frames 39 is fixed with a driving motor 44 through a motor frame, and the output end of the driving motor 44 is fixed to the outer end of the screw rod 40 through a coupling.

[0063] It should be noted that: by rotating the driving motor 44, one of the screw rods 40 is driven to rotate, and under the action of the two rotating gears 42 and the toothed belt 43, the two screw rods 40 rotate synchronously, thereby driving the moving seat 41 to move in the U-shaped frame 39, so that the placing mechanism 3 moves back and forth between the loading piece 5 and the conveyor belt of the oven furnace, which is convenient for installing the placing frame 2 into the placing mechanism 3 and discharging the placing frame 2 in the placing mechanism 3.

[0064] In this solution, in order to ensure that multiple display frames 2 are stacked and installed stably, the distance between the top of the pull plate 4 and the bottom of the display frame 2 is designed to be consistent with the distance between two adjacent display plates 18, and the pull plate 4 is located in the middle of both sides of the display frame 2. The design of the pull plate 4 is also convenient for personnel to directly hold it, which is convenient for taking the display frame 2;

[0065] Specifically, refer to Figure 1 and Figure 2A conveyor belt 45 is arranged on the outside of the loading piece 5, and a receiving frame is placed at the discharge end of the infrared oven body 1. The conveyor belt 45 is used for conveying the placing frame 2, thereby further freeing up manpower and realizing that the placing frame 2 with the material is input into the loading piece 5 and automatically pushed into the placing mechanism 3.

[0066] In this solution, a working method of an infrared oven is also disclosed, comprising the following steps:

[0067] S1. The personnel places the material on the conveyor belt 45, and then moves the placing frame 2 to the loading piece 5 through the conveyor belt 45;

[0068] S2. By raising the loading member 5, the placing frame 2 is pushed upward, so that the placing frame 2 moves upward toward the bottom of the two groups of placing mechanisms 3, and squeezes the placing member 13 at the bottom until it is engaged with the placing member 13;

[0069] S3 repeats S1-S2 until the two sets of placement mechanism 3 are placed in a sufficient amount of placement frame 2;

[0070] S4. The two groups of placing mechanisms 3 are synchronously moved to the upper part of the conveyor belt of the feeding end of the infrared oven body 1 by the moving assembly 6, and the linkage rod 25 in the linkage member 15 is located above the pallet 36 of the loading member 5;

[0071] S5. The loading member 5 continues to move up and down, so that the linkage rod 25 moves up and down, thereby driving the multiple rings 16 to rotate synchronously, and the stacked multiple placement frames 2 fall sequentially onto the conveyor belt of the infrared oven;

[0072] S6. After all the objects have fallen, the two sets of placement mechanisms 3 are retracted and reset through the moving assembly 6, and S1-S5 are repeated.

[0073] The principle of realizing the stacking and subsequent unloading of the placing frames 2 is as follows: when drying, heating and drying the materials, the personnel first place the materials to be processed in the placing frames 2, and then move them to the support plate 36 in sequence through the conveyor belt 45, and raise it through the electric push rod 35 to connect with the four placing pieces 13 at the lowest end, and then push up the multiple placing frames 2 in sequence, so that the multiple placing frames 2 are stacked in the multi-layer placing pieces 13, and then the placing mechanism 3 and the stacked placing frames 2 are moved to the top of the conveyor belt of the oven furnace through the moving component 6, and connected with the charging piece 5 through the linkage member 15, so as to drive the connecting plate 14 to move up and down, so that the adjusting plate 10 moves up and down synchronously, so that the adjusting rod 22 moves along the track opening 21, and at the same time drives the ring 16 to rotate, so as to realize the sequential downward movement of the multiple placing frames 2 stacked together, and the placing frame 2 at the lowest end directly falls onto the conveyor belt and enters the oven furnace, thereby realizing automatic loading and unloading, freeing up manpower, and no personnel are required to perform loading operations all the time.

[0074] In this scheme, if Figure 1 As shown in FIG. 1 , when the placing mechanism 3 is moved to the charging member 5 by the moving assembly 6, it is in the loading state, and the placing mechanism 3 is moved to the conveyor belt of the oven by the moving assembly 6, as shown in FIG. Figure 2 The figure shows the blanking form.

[0075] Embodiment 2

[0076] Reference Figure 5 , Figure 7 , Fig. 9 and Fig.10 As shown, this embodiment further illustrates the first embodiment, the linkage member 15 in the figure includes an L-shaped frame 23 fixed to the outside of the support rod 7, a rotating plate 24 is rotatably mounted on the top of the L-shaped frame 23 through a rotating shaft, and a linkage rod 25 adapted to the charging member 5 is fixed to one end of the rotating plate 24, a docking block 26 is fixed to the other end of the rotating plate 24, a docking seat 27 adapted to the docking block 26 is fixed to the outside of the connecting plate 14, and a reset member 28 connected to the L-shaped frame 23 is mounted on the rotating plate 24;

[0077] The reset member 28 includes an arc-shaped rod 29 fixed to the bottom of the rotating plate 24, one end of the arc-shaped rod 29 slides through the L-shaped frame 23 and is fixed with a limiting ball 30, and the outer side of the arc-shaped rod 29 is sleeved with an arc-shaped spring 31 that abuts against the L-shaped frame 23 and the rotating plate 24;

[0078] The principle of the linkage member 15 driving the connecting plate 14 to move up and down is as follows: first, the placing mechanism 3 is moved to the top of the conveyor belt of the oven furnace through the moving assembly 6, and then the linkage rod 25 is abutted against the supporting plate 36 on the charging member 5. Then, as the electric push rod 35 rises, the linkage rod 25 is driven to rise accordingly, so that the rotating plate 24 rotates accordingly, so that the docking block 26 at one end directly squeezes the docking seat 27, driving the connecting plate 14 to move down, and then the electric push rod 35 retracts, and the arc spring 31 in the reset member 28 causes the rotating plate 24 to rotate and reset accordingly. At the same time, under the action of the pushing spring 11 at the bottom of the adjusting plate 10, the adjusting plate 10 and the connecting plate 14 are moved up and reset, which is convenient for the next downward pressure. The extension and retraction of the electric push rod 35 is cleverly utilized. In the process of pushing the placing frame 2, the linkage member 15 can be triggered after the placing mechanism 3 is shifted, and power is provided again to help it perform the unloading operation.
