Description

Technical Field

[0001] The utility model relates to the field of automobile sealing strip processing, and specifically to a loading and unloading mechanism for an automobile sealing strip spraying oven. Background Art

[0002] After the spraying process of the automobile sealing strip, in order to quickly dry the anti-aging agent on the surface of the automobile sealing strip, an oven can be used to heat and dry the automobile sealing strip.

[0003] The automobile sealing strip is mainly composed of rubber. When drying in the oven, the rubber and the anti-aging agent will generate relatively serious peculiar smells when heated. When loading and unloading on the existing oven, the oven door is in an open state all the time. In this state, the peculiar smell of the oven will directly overflow from the oven door, resulting in the deterioration of the working environment. Therefore, a sealing device can be added at the opening of the oven door, so that when the oven is loaded and unloaded and the oven door is opened, the inside of the oven is in a relatively closed state, avoiding the direct outward diffusion of the gas in the oven through the oven door during the loading and unloading process. Summary of the Utility Model

[0004] Aiming at the problems in the prior art that when using an oven to dry the anti-aging agent of an automobile sealing strip, the automobile sealing strip and the anti-aging agent generate peculiar smells when heated; and during the loading and unloading process, the oven door is in an open state all the time, and the peculiar smell in the oven directly diffuses to the outside from the oven door, resulting in the deterioration of the working environment, a loading and unloading mechanism for an automobile sealing strip spraying oven is provided.

[0005] In order to solve the above technical problems, the utility model is solved by the following technical solutions:[[]]END

[0006] A loading and unloading mechanism for an automobile sealing strip spraying oven, including a conveyor belt for loading and unloading the oven. An isolation bin for sealing the inlet or outlet of the oven is provided on the conveyor belt. Two first mounting seats are provided on the upper inner wall of the isolation bin. Isolation doors are respectively installed on the two first mounting seats. A chute with an opening downward is provided on the first mounting seat. The isolation door can move up and down in the chute; a driving mechanism for driving the isolation door to move upward and a motor for controlling the operation of the driving mechanism are provided in the isolation bin;

[0007] The loading and unloading mechanism further includes an induction mechanism for controlling the opening or closing of the motor at each isolation door. The induction mechanism includes a first conductor and a second conductor provided on the side of the isolation door far from the oven; a plurality of placement seats are arranged at intervals on the conveyor belt, and a third conductor is provided on the placement seat; when the placement seat on the conveyor belt passes through the positions where the first conductor and the second conductor are located, the first conductor, the second conductor, the third conductor and the motor form a closed loop.

[0008] The utility model seals the inlet and outlet of the oven through an isolation chamber; when the object placement seat moves to the front of the isolation door along with the conveyor belt, the third conductor on the object placement seat is electrically connected to the first conductor and the second conductor in front of the corresponding isolation door, and then forms a closed loop with the motor. The motor operates to control the driving mechanism to drive the corresponding isolation door to move into the chute; when the tail of the object placement seat leaves the position where the first conductor and the second conductor are located, the third conductor disconnects the connection with the first conductor and the second conductor, the motor is powered off, and the driving mechanism stops operating. The isolation door falls under the action of gravity. Before the isolation door falls to the height position of the upper surface of the object placement seat, the tail of the object placement seat passes through the isolation door under the action of the conveyor belt. Through the above settings, it is preferably realized to open and close the corresponding isolation door according to the movement of the object placement seat. Since the two isolation doors are not in the state of being opened simultaneously, the peculiar smell in the oven can be effectively prevented from being discharged into the air through the isolation chamber.

[0009] Preferably, rolling bodies are installed on the bottom wall of the isolation door. The lower ends of the rolling bodies abut against the conveyor belt and can rotate along with the movement of the conveyor belt.

[0010] If the isolation door in the utility model directly abuts against the conveyor belt, during the movement of the conveyor belt, the isolation door and the conveyor belt will be damaged due to friction; if in order to avoid friction, a gap is left between the isolation door and the conveyor belt, the sealing performance of the isolation chamber will be reduced, resulting in the peculiar smell in the oven flowing out from the gap. Therefore, rolling bodies are installed on the bottom wall of the isolation door. The rolling bodies abut against the conveyor belt to avoid gaps in the isolation chamber; at the same time, the rolling bodies can rotate along with the movement of the conveyor belt, changing the sliding friction between the isolation door and the conveyor belt into rolling friction; reducing the loss generated by friction between the rolling bodies and the conveyor belt during operation.

[0011] Preferably, the chute is recessed inward to form a first limiting groove. One end of the isolation door far from the conveyor belt extends towards the first limiting groove to form an extension end. A shock-absorbing spring is provided between the bottom wall of the extension end and the bottom wall of the first limiting groove. The shock-absorbing spring is used to abut the extension end away from the bottom wall of the first limiting groove.

[0012] By setting the shock-absorbing spring in the utility model, after the motor is powered off, the falling speed of the isolation door becomes slower; the falling time of the isolation door is prolonged, ensuring that the tail of the object placement seat can pass through the isolation door within the corresponding time. At the same time, the collision force between the isolation door and the conveyor belt can be weakened, reducing the working loss of the conveyor belt and the isolation door.

[0013] Preferably, both ends of the bottom wall of the isolation door extend downward to form extension ends. The rolling bodies are arranged as cylinders. A positioning shaft is fixed at the center of the axis of the cylinder of the rolling body. A positioning hole for inserting the positioning shaft is provided in the extension end, and the positioning shaft can rotate in the positioning hole.

[0014] In the present utility model, the rolling elements are set as cylindrical, and the installation of the cylindrical rolling elements is realized through the cooperation of the positioning holes and the positioning shafts. Among them, the rolling elements are set as integrally formed cylinders, which have better sealing performance for the isolation chamber compared with other forms of rolling elements such as ball bearings, and the installation is more simple.

[0015] Preferably, the extension end includes a first extension component fixed on the isolation plate, and a second extension component is detachably installed below the first extension component. The first extension component and the second extension component respectively recess inward to form semi-circular grooves. When the second extension component is installed on the first extension component, the two semi-circular grooves form a limiting hole.

[0016] In the present utility model, by detachably installing the second extension end on the first extension end, the disassembly and installation of the rolling elements can be realized more conveniently.

[0017] Preferably, screw holes are coaxially provided on both the first extension end component and the second extension end component, and a nut is also provided on the second extension end component. The nut cooperates with the screw holes to fix the second extension end component on the first extension end component.

[0018] In the present utility model, the installation of the first extension end component and the second extension end component can be realized more simply through the cooperation of the nut and the screw holes.

[0019] Preferably, an installation groove is provided on the bottom wall of the first extension component. The side wall of the installation groove recesses inward to form a second limiting groove. A limiting plate is provided in the second limiting groove, and a spring for pushing the limiting plate out of the second limiting groove is also provided in the second limiting groove. One end of the limiting plate is fixedly connected with a fixing column, and one end of the fixing column passes through the side wall of the installation groove and extends out of the installation groove; an installation plate for placing in the installation groove is provided on the second extension component, and one end of the installation plate far from the second extension component extends outward to form a limiting end. The limiting end cooperates with the limiting plate to limit the second extension component.

[0020] When the second extension component of the present utility model is installed on the first extension component, the limiting plate extends out of the installation groove under the action of the limiting spring, and the installation of the second extension component is realized through the cooperation of the limiting plate and the limiting end; when disassembly is required, the fixing column is pulled outwards, the limiting plate contracts into the second limiting groove, and the limiting plate is separated from the limiting end in contact, and then the second extension component is disassembled. During the operation of the loading and unloading mechanism, the first extension component and the second extension component will be repeatedly impacted. If directly fixed with nuts, the nuts will become loose during repeated impacts; while using the fixing method of cooperating the limiting plate and the limiting end, it will not become loose due to impacts, and the influence of impacts on the structure of the extension end can be avoided.

Detailed implementation manners

[0028] To further understand the content of the present invention, the present invention will be described in detail in combination with the drawings and embodiments. It should be understood that the embodiments are only for explaining the present invention rather than limiting it.

[0029] Embodiment 1

[0030] During the process of using the conveyor belt 110 to load and unload the oven machine, the door of the oven machine is in an open state, and the odor generated by the heating of the automotive sealing strip and the anti-aging agent in the oven will directly overflow from the door; as Figure 1 shown, in this embodiment, an isolation chamber 120 is provided at the door of the oven machine, and the inner cavity of the oven machine is in a relatively sealed state through the isolation chamber 120.

[0031] There are two isolation doors 130 inside the isolation chamber 120. The isolation doors 130 can move up and down in the chute 1701 opened on the mounting seat 170 of the isolation chamber 120, so as to realize the opening and closing of the isolation chamber 120. The two isolation doors 130 are in a normally closed state. When the automotive sealing strip on the conveyor belt 110 passes through, the isolation door 130 at the corresponding position opens, and the two isolation doors 130 do not open simultaneously, so as to avoid the direct connection between the inner cavity of the oven and the outside. There is a driving mechanism 180 for driving the isolation door 130 to move upward and a motor for controlling the operation of the driving mechanism 180 inside the isolation chamber 120.

[0032] There are multiple object placement seats 160 arranged at intervals on the conveyor belt 110, and the automotive sealing strip is placed inside the object placement seats 160; in order to make the isolation door 130 open in time when the object placement seat 160 passes through, there is an induction mechanism for controlling the opening or closing of the motor at each isolation door 130. The induction mechanism includes a first conductor 140 and a second conductor 150 arranged on the side of the isolation door 130 far from the oven; there are multiple object placement seats 160 arranged at intervals on the conveyor belt 110, and a third conductor 1601 is provided on the object placement seat 160; when the object placement seat 160 on the conveyor belt 110 passes through the positions where the first conductor 140 and the second conductor 150 are located, the first conductor 140, the second conductor 150, the third conductor 1601 and the motor form a closed circuit.

[0033] When the object placement seat 160 of this embodiment moves to the front of the isolation door 130 along with the conveyor belt 110, the third conductor on the object placement seat 160 is electrically connected to the first conductor 140 and the second conductor 150 in front of the corresponding isolation door 130, and then forms a closed circuit with the motor. The motor operates to control the driving mechanism to drive the corresponding isolation door 130 to move into the chute 1701; when the tail of the object placement seat 160 leaves the positions where the first conductor 140 and the second conductor 150 are located, the third conductor 1601 disconnects from the first conductor 140 and the second conductor 150, the motor is powered off, the driving mechanism stops operating, and the isolation door 130 falls under the action of gravity. Before the isolation door 130 falls to the height position of the upper surface of the object placement seat 160, the tail of the object placement seat 160 passes through the isolation door 130 under the action of the conveyor belt 110.

[0034] In order to ensure that when the third conductor 1601 disconnects from the first conductor 140 and the second conductor 150, the tail of the object placement seat 160 has not passed through the isolation door 130. At this time, the isolation door 130 falls under the action of gravity. In order to enable the object placement seat 160 to pass through the isolation door 130 smoothly, the positions of the first conductor 140 and the second conductor 150 should be as close to the isolation door 130 as possible.

[0035] Such as Figure 3In order to slow down the falling speed of the isolation door 130 and leave sufficient time for the tail of the storage seat 160 through the isolation door 130, a first limiting groove 1702 can be opened on the inner wall of the sliding groove 1701. One end of the isolation door 130 far from the conveyor belt 110 extends towards the first limiting groove 1702 to form an extension end 1302. A shock-absorbing spring 1703 is provided between the bottom wall of the extension end 1302 and the bottom wall of the first limiting groove 1702. At the same time, the shock-absorbing spring 1703 can reduce the impact force between the isolation door 130 and the conveyor belt 110 and reduce the loss of the isolation door 130 and the conveyor belt 110.

[0036] During actual use, if the isolation door 130 directly abuts against the conveyor belt 110, the isolation door 130 and the conveyor belt 110 will be damaged due to friction during the movement of the conveyor belt 110; if in order to avoid friction, there is a gap between the isolation door 130 and the conveyor belt 110, the sealing effect of the isolation door 130 on the isolation bin 120 will be reduced, resulting in the odor in the oven flowing out from the gap. Therefore, rolling elements 1301 are installed on the bottom wall of the isolation door 130, and the rolling elements 1301 abut against the conveyor belt 110, avoiding gaps in the isolation bin 120 and improving the sealing performance of the isolation bin 120; at the same time, the rolling elements 1301 can rotate with the movement of the conveyor belt 110, changing the sliding friction between the isolation door 130 and the conveyor belt 110 into rolling friction; reducing the loss caused by friction between the rolling elements 1301 and the conveyor belt 110 during operation.

[0037] The rolling elements 1301 can be set in various forms such as ball bearings and rollers; for example Figure 2 As shown in the figure, in this embodiment, the rolling elements 1301 are set as cylinders. A positioning shaft 1303 is fixed at the axis of the cylinder of the rolling element 1301. A positioning hole for inserting the positioning shaft 1303 is provided in the extension end 1302, and the positioning shaft 1303 can rotate in the positioning hole. Setting the rolling elements 1301 as integrally formed cylinders has better sealing performance for the isolation bin 120 and is easier to install compared to other forms of rolling parts such as ball bearings.

[0038] The rolling elements 1301 will be worn during use and often need to be replaced; therefore, as Figure 4 shown, the extension end 1302 is set with a structure that is easy to disassemble, which includes a first extension component 1304 fixed on the isolation plate. A second extension component 1305 is detachably installed below the first extension component 1304. The first extension component 1304 and the second extension component 1305 respectively recess inward to form semi-circular grooves. When the second extension component 1305 is fixed on the first extension component 1304 using a nut 1307, the two semi-circular grooves form a limiting hole 1306.

[0039] Embodiment 2

[0040] During the use of the loading and unloading mechanism, the isolation door 130 will repeatedly impact the conveyor belt 110. In Embodiment 1, although it is relatively simple to install the second extension component 1305 using the nut 1307, during its use, the nut 1307 will loosen due to the impact. Therefore, as Figure 5 shown, an installation groove 1308 is provided on the bottom wall of the first extension component 1304. The side wall of the installation groove 1308 is recessed inward to form a second limiting groove 1309. A limiting plate 1310 is provided in the second limiting groove 1309. A spring for pushing the limiting plate 1310 out of the second limiting groove 1309 is also provided in the second limiting groove 1309. One end of the limiting plate 1310 is fixedly connected with a fixing column 1312. One end of the fixing column 1312 passes through the side wall of the installation groove 1308 and extends out of the installation groove 1308; an installation plate 1313 for placing in the installation groove 1308 is provided on the second extension component 1305. One end of the installation plate 1313 far from the second extension component extends outward to form a limiting end 1314. The limiting end 1314 cooperates with the limiting plate 1310 to limit the second extension component 1305. This connection method is less affected by impacts and preferably improves the stability of the structure of the extension end 1302.

[0041] In the use state of the isolation door 130, the limiting plate 1310 extends out of the installation groove 1308 under the action of the limiting spring 1311, and the installation of the second extension component 1305 is realized through the cooperation of the limiting plate 1310 and the limiting end 1314. When disassembly is required, the fixing column 1312 is pulled outwards, the limiting plate 1310 contracts into the second limiting groove 1309, and the limiting plate 1310 is separated from the limiting end 1314, thereby disassembling the second extension component 1305.

[0042] In summary, the above are only the preferred embodiments of this embodiment. All equivalent changes and modifications made according to the scope of the patent application of this embodiment shall fall within the scope covered by the patent of this embodiment.
