Description

Technical Field

[0001] This utility model relates to the field of oven technology, and in particular to a hot air oven with an automatic lifting door. Background Technology

[0002] Ovens are used to quickly evaporate moisture from products and are commonly used in coating and plating processes. Due to the high temperatures in ovens, the opening and closing of their doors is usually automated. For example, Chinese invention patent CN202410596622.9 discloses an automatic opening and closing sealing door and an oven with such a sealing door, which uses a cylinder to extend and retract to control the door's rotation, thereby achieving the opening and closing of the oven.

[0003] However, this solution has the following drawbacks: it uses a rotating door opening method, which results in a large space requirement. Summary of the Invention

[0004] This utility model addresses the problems of existing technology by providing a hot air oven with an automatic lifting door. By raising and lowering the door, it makes reasonable use of three-dimensional space, thereby reducing the space requirement.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] This utility model provides an automatic lifting door hot air oven, which includes a cabinet and a door that is movably disposed in the cabinet. A lifting mechanism is provided between the cabinet and the door. The lifting mechanism includes a lifting motor, a lifting reducer, and a transmission module. The lifting motor drives and connects to the lifting reducer. The transmission module is installed at the output end of the lifting reducer and is used to drive the door to lift relative to the cabinet.

[0007] A clamping mechanism is also provided between the door and the box, which is used to press the door towards the box.

[0008] Furthermore, the transmission module includes a transmission rod and two transmission components. The transmission rod is installed at the output end of the lifting reducer, and the two transmission components are respectively installed at both ends of the door and are connected to the transmission rod. The transmission rod drives the door to rise and fall relative to the box through the two transmission components.

[0009] Furthermore, the transmission assembly includes a driving gear, a driven gear, and a chain. The transmission rod is connected to the driving gear, the driven gear is installed in the housing, and the two ends of the chain are respectively wound around the driving gear and the driven gear. The chain is connected to the door.

[0010] Furthermore, the transmission assembly also includes a first gear and a second gear, the first gear being mounted on the transmission rod, the second gear meshing with the first gear, the second gear being mounted on a transmission shaft, and the drive gear being mounted on the transmission shaft;

[0011] The first gear rotates synchronously with the transmission rod, and the second gear rotates synchronously with the transmission shaft. The first gear and the second gear are perpendicular to each other.

[0012] Furthermore, the transmission assembly also includes a guide rail and a slider. The guide rail is installed on the housing, the slider is installed on the door, and the slider is slidably mounted on the guide rail.

[0013] Furthermore, the clamping mechanism includes a clamping cylinder and a clamping module. The clamping cylinder is used to drive the clamping module to move closer to or away from the door, and the clamping module is used to hold the door.

[0014] Furthermore, the clamping module includes a mounting component and at least one clamping wheel, which is mounted on the piston rod of the clamping cylinder. The clamping wheel is rotatably mounted on the mounting component and is used to press against the door body.

[0015] Furthermore, each of the two sides of the housing is provided with an extension plate at one end close to the other, a pressing cylinder is installed at the end of the extension plate away from the housing, and the mounting component is located at the end of the extension plate close to the housing.

[0016] There are two pressure rollers, which are respectively rotatably mounted on the top and bottom of the mounting component.

[0017] Furthermore, the enclosure is also equipped with a signal transceiver, which is used to communicate with external AGV vehicles.

[0018] Furthermore, the inner wall of the enclosure is provided with multiple ventilation holes, and the door has an inner panel and an outer panel, with the outer panel of the door having several compensation holes.

[0019] The beneficial effects of this utility model are as follows: This utility model opens and closes the door by driving the door body to rise and fall relative to the box body through a lifting mechanism, thereby reducing the space requirement.

Detailed Implementation

[0026] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention. The present invention will be described in detail below with reference to the accompanying drawings.

[0027] like Figures 1 to 5 As shown, the present invention provides an automatic lifting door hot air oven, including a cabinet 1 and a door 2 movably disposed on the cabinet 1. A lifting mechanism 3 is provided between the cabinet 1 and the door 2. The lifting mechanism 3 includes a lifting motor 31, a lifting reducer 32, and a transmission module 33. The lifting motor 31 drives the lifting reducer 32, and the transmission module 33 is installed at the output end of the lifting reducer 32. The transmission module 33 is used to drive the door 2 to lift relative to the cabinet 1.

[0028] A pressing mechanism 4 is also provided between the door 2 and the box 1. The pressing mechanism 4 is used to press the door 2 toward the box 1.

[0029] In practical use, this utility model can be used in conjunction with an AGV trolley, that is, the box 1 is also equipped with a signal transceiver, which is used to communicate with the AGV trolley outside.

[0030] The AGV (Automated Guided Vehicle) is used to transport products that need to be dried from the coating line or other equipment to this utility model. The AGV interacts with this utility model via signals. When this utility model is empty or has products that are about to be dried (these products are also loaded by the AGV), the AGV moves in front of this utility model and waits for this utility model to use the lifting mechanism 3 to raise the door 2, allowing the AGV inside the box 1 to leave the box 1 carrying the dried products. Then, the AGV carrying the products to be dried can enter the box 1. Subsequently, the lifting mechanism 3 drives the door 2 to descend, and drying can be carried out again.

[0031] This invention achieves a space-efficient design by raising and lowering the door 2, allowing it to open without occupying too much space in front, so that the AGV can wait directly in front of the box 1 without interfering with the opening and closing of the door 2.

[0032] In this embodiment, the transmission module 33 includes a transmission rod 34 and two transmission components 35. The transmission rod 34 is installed at the output end of the lifting reducer 32, and the two transmission components 35 are respectively installed at both ends of the door body 2 and are connected to the transmission rod 34. The transmission rod 34 drives the door body 2 to rise and fall relative to the box body 1 through the two transmission components 35.

[0033] In other words, this utility model uses the rotation of the lifting motor 31, and the power of the lifting motor 31 is reduced and increased by the lifting reducer 32 before being output to two transmission components 35. The two transmission components work together to keep the two sides of the door 2 at basically the same speed for lifting and lowering, thus ensuring the stability of the lifting and lowering of the door 2.

[0034] Specifically, the transmission assembly 35 includes a driving gear 351, a driven gear 352, and a chain 353. The transmission rod 34 is connected to the driving gear 351. The driven gear 352 is mounted on the housing 1. The two ends of the chain 353 are respectively wound around the driving gear 351 and the driven gear 352, and the chain 353 is connected to the door body 2. That is, the power of the lifting motor 31 is ultimately converted into the power to rotate the chain 353, which drives the door body 2 to lift and lower. The lifting motor 31 of this invention is preferably a servo motor, which has the advantage of high precision, ensuring stable lifting accuracy of the door body 2 and preventing the transmission between components from being affected by excessive lifting amplitude, thus guaranteeing stability.

[0035] In actual use, the door 2 is fixed to the chain 353 by the connector 20, so that it rises and falls with the movement of the chain 353.

[0036] Specifically, the transmission assembly 35 further includes a first gear 354 and a second gear 355. The first gear 354 is mounted on the transmission rod 34, and the second gear 355 meshes with the first gear 354. The second gear 355 is mounted on a transmission shaft 356, and the drive gear 351 is mounted on the transmission shaft 356. The first gear 354 rotates synchronously with the transmission rod 34, and the second gear 355 rotates synchronously with the transmission shaft 356.

[0037] In actual use, the first gear 354 and the second gear 355 are perpendicular to each other. The specific operation of the lifting mechanism 3 is as follows: the lifting motor 31 rotates, which drives the transmission rod 34 to rotate through the lifting reducer 32, so that the two first gears 354 rotate. The first gear 354 drives the second gear 355 to rotate, thereby driving the only drive gear 351 to rotate, so as to achieve the effect of making the chain 353 move.

[0038] Since the first gear 354 and the second gear 355 are perpendicular to each other, the driving gear 351 is also perpendicular to the first gear 354. This allows the driving gear 351 to be directly positioned in front of the housing 1 and on the side of the door 2. Consequently, the chain 353 is also positioned in front of the housing 1, resulting in better transmission and preventing the width of this utility model from becoming too large.

[0039] Specifically, the transmission assembly 35 also includes a guide rail 357 and a slider 358. The guide rail 357 is installed on the housing 1, and the slider 358 is installed on the door 2. The slider 358 is slidably set on the guide rail 357, thereby achieving the effect of guiding the door 2 to rise and fall reliably.

[0040] In this embodiment, the pressing mechanism 4 includes a pressing cylinder 41 and a pressing module 42. The pressing cylinder 41 is used to drive the pressing module 42 to move closer to or away from the door 2, and the pressing module 42 is used to press the door 2. That is, when the door 2 descends to a predetermined height, the pressing cylinder 41 drives the pressing module 42 to move, so that the pressing module 42 presses the door 2, thereby closing the gap between the door 2 and the box 1, ensuring that no excessive heat is dissipated to the outside during the drying process, thus ensuring the drying efficiency.

[0041] Specifically, the clamping module 42 includes a mounting member 43 and at least one clamping roller 44 mounted on the piston rod of the clamping cylinder 41. The clamping roller 44 is rotatably mounted on the mounting member 43 and is used to press against the door body 2. By using the clamping roller 44 to press against the door body 2, the pressure between the door body 2 and the clamping module 42 can be reduced. When the door body 2 is raised or lowered, there is no need for the clamping roller 44 to retract excessively. When the clamping roller 44 presses against the door body 2, the friction between the door body 2 and the clamping roller 44 will not be too large, thus reducing the stroke requirement of the clamping module 42 and further optimizing the space requirements.

[0042] Specifically, the two sides of the housing 1 are respectively provided with extension plates 11 at their respective ends close to each other, the pressing cylinder 41 is installed at the end of the extension plate 11 away from the housing 1, and the mounting component 43 is located at the end of the extension plate 11 close to the housing 1; there are two pressing wheels 44, which are respectively rotatably set at the top and bottom of the mounting component 43.

[0043] The extension plate 11 is positioned so that the pressing mechanism 4 is located directly in front of the box 1, thereby achieving the effect of directly pressing the door 2 against the box 1.

[0044] In this embodiment, the inner wall of the box 1 is provided with a plurality of ventilation holes 12, and the door 2 has an inner plate 21 and an outer plate 22, and the outer plate 22 of the door 2 is provided with a plurality of compensation holes 23.

[0045] Multiple ventilation holes 12 are arranged in a rectangular array on the inner wall of the box 1, which makes the air outlet uniform and ensures the drying effect. The combination of the inner panel 21 and the outer panel 22 makes the heat preservation effect of this utility model better, and the compensation hole 23 allows the gas to interact with the outside in time when the air pressure between the inner panel 21 and the outer panel 22 changes, ensuring stable air pressure and preventing the door 2 from deforming.

[0046] The inner panel 21 can be made of heat-insulating material, which has a very low thermal conductivity, but heat will still be dissipated, so compensation holes 23 need to be provided for compensation.

[0047] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and modifications made to the above embodiments based on the present utility model without departing from the scope of the present utility model shall fall within the scope of the present utility model.
