Description

Technical Field

[0001] This utility model relates to the field of spraying and drying technology, and in particular to a drying device for spraying metal cabinet panels. Background Technology

[0002] A drying device is a piece of equipment used to dry materials, typically consisting of a heating unit, a conveying unit, and a ventilation unit. After paint is sprayed onto the surface of a metal cabinet panel, a drying device is needed to dry the coated part. The drying device provides a stable temperature and humidity environment, allowing the coating to dry quickly and evenly within a set time, thereby improving the coating's adhesion and durability. At the same time, the drying channel reduces the impact of human operation, improving the stability of coating quality.

[0003] However, existing drying equipment is not convenient for adjusting the size of the drying chamber, which easily leads to energy waste. Since the metal cabinet panels are of different sizes, a taller drying chamber can dry longer cabinet panels. When it is necessary to dry shorter cabinet panels, the utilization rate of the drying chamber is low. In order to maintain the temperature inside the drying chamber, the entire drying chamber needs to be continuously heated, resulting in energy waste.

[0004] Therefore, this application proposes a drying device that reduces the energy used to heat the drying chamber by adjusting the size of the drying chamber, thereby reducing energy waste. Utility Model Content

[0005] The purpose of this utility model is to solve the problems in the prior art by proposing a drying device for spraying metal cabinet panels.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A drying device for spraying metal cabinet panels includes a box body and a drying chamber located in the middle of the box body. Multiple air outlets communicating with a combustion chamber are respectively opened on both sides of the drying chamber. An adjustment component for adjusting the size of the drying chamber is provided in the drying chamber. The adjustment component includes a bottom plate that slides vertically in the drying chamber and a first heat insulation pad for sealing the air outlets. The bottom plate slides up and down on the inner wall of the drying chamber through a lifting component.

[0008] In some embodiments, the adjustment assembly further includes a first winch wheel rotatably connected to the bottom of the drying chamber near the air outlet, the first heat insulation pad being wound around the surface of the first winch wheel, the other end of the first heat insulation pad being fixed to the lower surface of the base plate, and there are two sets of the first heat insulation pad, which are symmetrically arranged inside the drying chamber.

[0009] In some embodiments, the lifting assembly includes two first guide rods fixed to the lower surface of the base plate and two second guide rods fixed to the bottom of the drying chamber. The surfaces of the two first guide rods are slidably connected to first sliding plates, and the surfaces of the two second guide rods are slidably connected to second sliding plates. Support rods are hinged to the upper surfaces of the two second sliding plates. There are multiple support rods, and the multiple support rods are rotatably connected by rotating shafts. The upper ends of the two topmost support rods are hinged to the lower surfaces of the two first sliding plates.

[0010] In some embodiments, the bottom of the drying chamber is symmetrically provided with sealing components for sealing the inlet and outlet of the drying chamber. The sealing components include a second winch that rotates at the bottom of the drying chamber and a second heat insulation pad wrapped around the surface of the second winch. The other end of the second heat insulation pad is fixed to the lower surface of the bottom plate.

[0011] In some embodiments, two sets of top-pressing assemblies are provided below the base plate for pressing the two first heat insulation pads tightly against the inner wall of the drying chamber. The top-pressing assemblies include multiple pressure rollers that can slide vertically and guide plates.

[0012] In some embodiments, a preheating chamber is provided at the front end of the housing, and the preheating chamber is connected to the drying chamber through an inlet located at the front end of the drying chamber.

[0013] Compared with the prior art, the present invention provides a drying device for spraying metal cabinet panels, which has the following beneficial effects.

[0014] 1. This utility model, by setting an adjustment component, allows the base plate to be raised and lowered within the drying chamber, thereby adjusting the size of the drying chamber to accommodate metal cabinets of different sizes. When drying smaller metal cabinets, reducing the space of the drying chamber reduces the amount of heat required to maintain the temperature inside the drying chamber, thereby reducing the emissions from the gas pipe and saving fuel.

[0015] 2. In this utility model, by setting up a top pressure component, multiple pressure rollers are used to press the first heat insulation pad tightly against the inner wall of the drying chamber during the adjustment of the bottom plate height, thereby preventing air from escaping through the air outlet located below the bottom plate and causing heat loss.

[0016] Other advantages, objectives and features of this invention will be set forth in part in the description which follows; and in part will be apparent to those skilled in the art upon examination of the following description; or may be taught from practice of this invention.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Reference Figure 1-8A drying device for spraying metal cabinet panels includes a housing 1 and a drying chamber 101 located in the middle of the housing 1. A preheating chamber 102 is located at the front end of the housing 1, and combustion chambers 103 are located on both sides of the housing 1, with the positions of the combustion chambers 103 corresponding to the drying chamber 101. Gas pipes 3 are respectively installed at the bottom of the two combustion chambers 103, and an electronically controlled valve for controlling the amount of gas emission is installed on the surface of the gas pipes 3. Two air supply boxes 2 are located at the rear end of the housing 1, which respectively supply air into the combustion chambers 103. The air supply boxes 2 are connected to the combustion chambers 103, and multiple fans 201 are fixed inside the air supply boxes 2. Multiple air outlets 4 connected to the combustion chambers 103 are opened on both sides of the drying chamber 101. A conveying mechanism for conveying metal cabinet panels is provided at the top of the housing 1. An inlet for the metal cabinet panels to enter the preheating chamber 102 is opened at the front end of the housing 1, and inlets and outlets for the metal cabinet panels to enter and exit are opened on both sides of the drying chamber 101.

[0029] Understandably, gas is delivered to the combustion chamber 103 via the gas pipe 3 and burned at the bottom of the combustion chamber 103 to generate heat. At the same time, outside air is delivered to the combustion chamber 103 via the air supply box 2 to provide oxygen. Meanwhile, the incoming air, carrying the heat generated by combustion, enters the drying chamber 101 through the air outlet 4, raising the temperature inside the drying chamber 101 to the specified temperature. Simultaneously, a portion of the temperature inside the drying chamber 101 dissipates into the preheating chamber 102 through the inlet of the drying chamber 101, raising the temperature inside the preheating chamber 102. The metal cabinet panel is conveyed to the preheating chamber 102 through the inlet via the conveying mechanism for preliminary preheating, and then moved to the drying chamber 101 through the inlet for drying. After drying, it is removed through the outlet.

[0030] Specifically, the drying chamber 101 is equipped with an adjustment component 5 for adjusting the size of the space in the drying chamber 101. The adjustment component 5 includes a bottom plate 501 that slides vertically in the drying chamber 101 and a first heat insulation pad 503 for sealing the air outlet 4. A first winch 502 is rotatably connected to the bottom of the drying chamber 101 near the air outlet 4. The first heat insulation pad 503 is wound around the surface of the first winch 502. The other end of the first heat insulation pad 503 is fixed to the lower surface of the bottom plate 501. Both ends of the first winch 502 are provided with spiral springs for driving the first winch 502 to automatically wind up the first heat insulation pad 503. There are two sets of the first heat insulation pad 503, which are symmetrically arranged inside the drying chamber 101. The bottom plate 501 slides up and down on the inner wall of the drying chamber 101 through the lifting component 6.

[0031] The lifting assembly 6 includes two first guide rods 601 fixed to the lower surface of the base plate 501 and two second guide rods 603 fixed to the bottom of the drying chamber 101. First slide plates 602 slide on the surfaces of the two first guide rods 601, and second slide plates 604 slide on the surfaces of the two second guide rods 603. A positive and negative threaded column 605 rotates at the bottom of the drying chamber 101, located between the two second guide rods 603. The two second slide plates 604 slide on the surfaces of the positive and negative threaded column 605 respectively. The positive and negative threaded column 605 is driven to rotate by a drive motor. Support rods 606 are hinged to the upper surfaces of the two second slide plates 604 respectively. There are multiple support rods 606, which are connected by rotating shafts. The upper ends of the two topmost support rods 606 are hinged to the lower surfaces of the two first slide plates 602 respectively.

[0032] Understandably, by driving the motor to rotate the positive and negative threaded column 605, the positive and negative threaded column 605 causes the two second sliding plates 604 to move closer to each other on the surfaces of the two second guide rods 603, causing the multiple support rods 606 to automatically adjust their support angles. At the same time, the first sliding plate 602 is driven to slide on the surface of the first guide rod 601, causing the bottom plate 501 to rise in the drying chamber 101, reducing the space of the drying chamber 101. Simultaneously, the bottom plate 501 pulls the first heat insulation pad 503 out from the surface of the first winch wheel 502, causing the first heat insulation pad 503 to seal the air outlet 4 below the bottom plate 501. By reducing the space of the drying chamber 101 and the number of air outlets 4, the heat required to maintain the temperature inside the drying chamber 101 can be reduced, thereby reducing the emissions from the gas pipe 3 to save fuel.

[0033] Specifically, the bottom of the drying chamber 101 is symmetrically provided with sealing components 7 for sealing the inlet and outlet of the drying chamber 101. The sealing components 7 include a second winch 701 rotating at the bottom of the drying chamber 101 and a second heat insulation pad 702 wrapped around the surface of the second winch 701. The other end of the second heat insulation pad 702 is fixed to the lower surface of the base plate 501. The inner wall of the drying chamber 101 is provided with a guide wheel 703 for pressing the second heat insulation pad 702 tightly against the inner wall of the drying chamber 101. Both ends of the second winch 701 are provided with spiral springs for driving the second winch 701 to automatically wind up the second heat insulation pad 702.

[0034] It is understandable that when the base plate 501 slides upward, it causes the two second heat insulation pads 702 to be released from the surface of the second winch 701. Under the action of the guide wheel 703, the second heat insulation pads 702 slide tightly against the inner wall of the drying chamber 101, which facilitates the sealing of the inlet and outlet of the drying chamber 101 below the base plate 501, and prevents heat from entering below the base plate 501 and causing waste.

[0035] Specifically, two sets of top-pressing components 8 are provided below the base plate 501 to tightly press the two first heat insulation pads 503 against the inner wall of the drying chamber 101, as shown in the reference. Figure 7 The top-pressing assembly 8 includes multiple pressure rollers 801 and a guide plate 802. Each pressure roller 801 has a slider 804 rotating at both ends. Slide grooves 803 are formed on both sides of the inner wall of the drying chamber 101. The multiple pressure rollers 801 slide within the two slide grooves 803 via the sliders 804. The guide plate 802 is fixed to both sides of the inner wall of the drying chamber 101, and the guide plate 802 and the multiple pressure rollers 801 are arranged sequentially from bottom to top. The side of the guide plate 802 that contacts the first heat insulation pad 503 has an arc surface. The top-pressing assembly 8 also includes components for driving the multiple pressure rollers... The roller 801 has multiple connecting rods 805 with uniformly adjustable spacing. The multiple connecting rods 805 are connected by multiple connecting shafts 806 in a cross-rotational manner. The connecting shaft 806 located at the top is fixed to the lower surface of the top plate, and the connecting shaft 806 located at the bottom is fixed to the side of the guide plate 802 away from the first heat insulation pad 503. The multiple connecting shafts 806 located in the middle are fixed with a connecting ring 807 at one end near the pressure roller 801. The connecting ring 807 is a "C"-shaped ring larger than half a circle. The multiple pressure rollers 801 rotate on the surface of the multiple connecting rings 807 respectively.

[0036] Understandably, when the base plate 501 slides upward, the connecting shaft 806 drives multiple connecting rods 805 to automatically adjust the support angle, so that the spacing between the multiple connecting shafts 806 located in the middle is evenly expanded. This causes the connecting ring 807 to drive multiple pressure rollers 801 to slide on the inner wall of the slide groove 803 through the slider 804. The height of the multiple pressure rollers 801 is adjusted according to the sliding of the base plate 501, so that the multiple pressure rollers 801 evenly press the first heat insulation pad 503, so that the first heat insulation pad 503 is tightly attached to the inner wall of the drying chamber 101 near the air outlet 4, preventing air from escaping from the air outlet 4 located below the base plate 501.

[0037] In this invention, gas is delivered to the combustion chamber 103 via the gas pipe 3, where it is burned at the bottom to generate heat. Simultaneously, outside air is supplied to the combustion chamber 103 via the air supply box 2, providing oxygen. The incoming air, carrying the heat generated by combustion, enters the drying chamber 101 through the air outlet 4, raising the temperature inside the drying chamber 101 to a specified level. A portion of the temperature inside the drying chamber 101 dissipates through the inlet into the preheating chamber 102, raising the temperature there as well. The metal cabinet panel is conveyed through the inlet to the preheating chamber 102 for initial preheating via a conveying mechanism, and then moved through the inlet to the drying chamber 101 for drying. After drying, the metal cabinet panel exits through the outlet... When drying smaller metal cabinet panels, the drive motor rotates the positive and negative threaded columns 605, causing multiple support rods 606 to raise the base plate 501 within the drying chamber 101, reducing the space of the drying chamber 101. Simultaneously, the base plate 501 pulls the first heat insulation pad 503 from the surface of the first winch wheel 502, and multiple pressure rollers 801 press the first heat insulation pad 503 against the inner wall of the drying chamber 101, thus sealing the air outlet 4 below the base plate 501. By reducing the space of the drying chamber 101 and the number of air outlets 4, the heat required to maintain the temperature inside the drying chamber 101 can be reduced, thereby reducing the emissions from the gas pipe 3 to save fuel.
