Description

Technical Field

[0001] This utility model relates to the field of baking equipment technology, and in particular to a small drying oven for quick-drying products. Background Technology

[0002] In the production and processing of some sheet materials, after the sheet materials have undergone spraying or adhesive bonding processes, they need to be dried quickly before proceeding to the next step. The existing drying methods mostly use tunnel ovens to dry sheet materials.

[0003] The tunnel furnace has a tunnel-shaped furnace chamber and achieves continuous material handling through a conveying system. The core structure includes a high-temperature resistant furnace body, a heating system, an intelligent temperature control system, and a conveying device. However, existing tunnel furnaces occupy a large area. Because tunnel furnaces have two independent inlets and outlets, their high-temperature insulation effect is poor. In addition, tunnel furnaces are long, and maintaining high temperatures for a long time consumes a lot of energy. Due to the long distance from the inlet to the outlet, the initial material baking and discharge time is long, making them unsuitable for small-batch production.

[0004] Therefore, how to reduce the floor space occupied by baking equipment, improve the drying efficiency of materials, and enhance the energy-saving and heat-preserving capabilities of drying equipment have become urgent technical challenges to be addressed. Utility Model Content

[0005] The purpose of this invention is to address one of the above-mentioned defects and provide a small drying oven for quick-drying products.

[0006] The objective of this utility model is achieved through the following means: A small oven for quick-drying products includes a box body, a baking rack, a heating device, and a lifting device. The box body has a baking cavity. The baking rack is a long, rectangular frame structure and is vertically movable within the baking cavity. The baking rack has several placement slots for horizontally placing sheet materials. The placement slots are arranged in a vertical row. The heating device heats the baking rack within the baking cavity. The lifting device is driven and connected to the baking rack. The box body has a feeding port that communicates with the baking cavity. The openings of the placement slots are parallel to the direction of the feeding port. The lifting device drives the baking rack to move up and down within the baking cavity, so that each placement slot from the top to the bottom of the baking rack can be connected to the feeding port for feeding or removing materials from the placement slots.

[0007] As a preferred embodiment, the box body has a double-layer structure, including an outer box and an insulated box. The outer box has a receiving cavity, and the insulated box and a lifting device are disposed in the receiving cavity. The lifting device is located on the lower side of the insulated box, and the baking cavity is located inside the insulated box. The outer box has an opening for the receiving cavity, and the insulated box has an opening for the baking cavity.

Detailed Implementation

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0019] To facilitate understanding, the present invention will now be described in further detail with reference to specific implementation examples, but this is not intended to limit the present invention.

[0020] like Figure 1-5As shown, this utility model discloses a small drying oven for quick-drying products, including a box body 1, a baking rack 2, a heating device, a lifting device, a heat insulation baffle 3, a feeding sensor 10, and a control circuit board 11. The box body 1 has a baking cavity 1021. The baking rack 2 has a long frame structure and is vertically movable in the baking cavity 1021. The baking rack 2 is provided with several placement slots 201 for horizontally placing sheet materials 9. The placement slots 201 are arranged in a row along the vertical direction. The heating device provides heating for the baking process. The baking rack 2 inside the cavity 1021 provides heating. A lifting device is connected to the baking rack 2. The housing 1 has a feeding port 103 communicating with the baking cavity 1021. The opening of the placement slot 201 faces parallel to the direction of the feeding port 103. The lifting device drives the baking rack 2 to move up and down within the baking cavity 1021, ensuring that each placement slot 201 from the top to the bottom of the baking rack 2 can connect to the feeding port 103 for feeding or removing material from the placement slot 201. By setting up a long, frame-like baking rack 2 and using a lifting device to drive it to move up and down quickly, the space occupied by the equipment is reduced. Only one feeding port 103 is used for feeding and removing material, improving the energy-saving and heat-preserving capabilities of the equipment. This allows the baking oven to maintain a high temperature, accelerating the drying of the sheet material 9, and enabling rapid removal of the dried material.

[0021] In this embodiment, the housing 1 has a double-layer structure, including an outer housing 101 and an insulated housing 102. The outer housing 101 has a receiving cavity 1011. The insulated housing 102 and a lifting device are disposed within the receiving cavity 1011. The lifting device is located on the lower side of the insulated housing 102. The baking cavity 1021 is located inside the insulated housing 102. The outer housing 101 has an opening for the receiving cavity, and the insulated housing 102 has an opening for the baking cavity. The openings of the receiving cavity and the baking cavity form a feeding port 103. The housing 1 adopts a double-layer design of the outer housing 101 and the insulated housing 102, which reduces the volume of the baking cavity 1021 and reduces heat loss. During the heating and baking processes, the feeding port can be sealed to further reduce heat loss.

[0022] The lifting device includes a stepper motor 6, a lead screw 7, and a lifting seat 8. The upper end of the lifting seat 8 extends into the baking cavity 1021 and is connected to the baking rack 2. The lower end of the lifting seat 8 is threadedly connected to the lead screw 7. The stepper motor 6 is fixedly installed in the accommodating cavity 1011. The stepper motor 6 drives the lifting seat 8 through the lead screw 7 to move the baking rack 2 up and down. The stepper motor 6 is separated from the baking cavity 1021 by the heat insulation box 102 and is adjacent to the mounting base by the lead screw 7, avoiding direct contact between the stepper motor 6 and high temperature, and preventing the stepper motor 6 from being affected by high temperature.

[0023] The heating device includes a heating element 4, a turbine fan 5, a partition plate 104, and insulation cotton. The partition plate 104 divides the baking chamber 1021 into a front chamber 10211 and a rear chamber 10212, and a heating port 105 is formed between the front chamber 10211 and the rear chamber 10212. The baking rack 2 is disposed in the front chamber 10211, and the heating element 4 and the turbine fan 5 are disposed in the rear chamber 10212. The turbine fan 5 is disposed on one side of the heating element 4, and the turbine fan 5 blows the heat generated by the heating element 4 from the rear chamber 10212 to the front chamber 10211 through the heating port 105.

[0024] The turbine fan 5 is arranged side by side with the heating tube 4. The turbine fan 5 is located on the side of the heating tube 4 away from the heating port 105. In this embodiment, the turbine fan 5 is located on the left side of the heating tube 4, and the heating port 105 is located on the right front side of the heating tube 4. The turbine fan 5 blows the heat from the heating tube 4 to the right towards the heating port 105.

[0025] The front cavity 10211 is equipped with heat insulation cotton on the left and right sides of the baking rack 2, namely left heat insulation cotton 107 and right heat insulation cotton 108, which are used to reduce heat loss and play a role in heat preservation and energy saving.

[0026] The right heat insulation cotton 108 is installed on the heat insulation baffle 3. The box 1 has a side door 106 for cleaning and maintenance on the right side. The side door 106 is connected to the front cavity 10211. The heat insulation baffle 3 is openable and closable at the side door 106. The right heat insulation cotton 108 passes through the side door 106 and blocks the right side of the front cavity 10211.

[0027] In this embodiment, the size of the side door 106 is adapted to the baking rack 2, which facilitates cleaning of the front cavity 10211 and also makes it convenient to disassemble the baking rack 2 for replacement or maintenance.

[0028] Each of the several placement slots 201 is provided with a set of support plates 202 at the bottom. Each set of support plates 202 includes a left support plate 202 and a right support plate 202. The left support plate 202 and the right support plate 202 in the same set are spaced apart and located on the same plane. They are used to support the sheet material 9 and expose the middle part of the sheet material 9, so that the sheet material 9 is heated evenly and the sheet material 9 is prevented from deforming due to uneven heating.

[0029] The side plate 203 of the baking rack 2 is provided with ventilation holes 204 to accelerate the air circulation between the placement slot 201 and the front cavity 10211 and improve the baking efficiency.

[0030] The feeding sensor 10 is located above the feeding port 103, and the control circuit board 11 is located on the outer casing. The control circuit board 10 is electrically connected to the feeding sensor 11 and the stepper motor 6 respectively.

[0031] The working process of this utility model is as follows: In the first round of baking, the heating device raises the temperature inside the baking cavity to a predetermined temperature. Using a lifting device, several placement slots 201 are aligned one by one with the feeding port 103 from top to bottom / bottom to top. An external robotic arm places sheet-like materials 8 one by one into the empty placement slots 201. When the feeding sensor 10 detects the external robotic arm, it sends a signal to the control circuit board 11. The control circuit board 11 controls the stepper motor 6 to stop operating and keep the baking rack 2 stationary. When the external robotic arm is completely withdrawn from the feeding port 103, the control circuit board 11 controls the stepper motor 6 to operate, causing the baking rack 2 to rise / fall. The rack descends to the next level and docks with the feeding port 103. When the first round of baking is completed and the second round of baking begins, the lifting device docks the baking rack 2 with the feeding port 103, which is initially placed in the placement slot 201 of the sheet material 9. The external robotic arm removes the dried sheet material 9. After removal, more sheet material 9 to be dried is placed in. After the feeding sensor 10 detects that the external robotic arm has entered and exited the feeding port 103 twice, the control circuit board 11 controls the baking rack 2 to move up / down to the next placement slot 201. The external robotic arm replaces the baked sheet material 9 with unbaked sheet material 9, and this process is repeated.

[0032] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
