Description

Technical Field

[0001] The utility model belongs to the technical field of sponge processing equipment and relates to an odor removal device for automotive interior sponge. Background Art

[0002] For the sponge used in automotive interior, due to the requirements of its application scenario, it needs to be subjected to heat odor removal treatment. In the prior art, the cut sponge coil is drawn through an oven, and the gas after the sponge is heated is evacuated, that is, hot air is blown from bottom to top, and then the waste gas is evacuated at the top of the oven. In this way, the hot air path is short, the heat utilization rate is low, and the sponge debris dust that may be generated during the heat drying process cannot be well separated from the sponge. Therefore, the current sponge odor removal heat drying method needs to be improved urgently. Summary of the Utility Model

[0003] The purpose of the utility model is to provide an odor removal device for automotive interior sponge aiming at the above problems existing in the prior art. The technical problem to be solved by the utility model is how to improve the heat utilization rate.

[0004] The purpose of the utility model can be realized by the following technical solutions: An odor removal device for automotive interior sponge, characterized in that it includes an oven, a unwinding structure located at one end of the oven, and a winding structure located at the other end of the oven. A plurality of traction and guiding units are arranged in the oven. The traction and guiding unit includes a roller rotatably connected in the oven, a blowing structure and an air extraction structure. The blowing structure is located at the top of the oven directly above the roller, and the air extraction structure is located at the top of the oven behind the roller. The traction and guiding unit further includes two guide rollers rotatably connected to both sides of the blowing structure respectively; the roller is of a mesh structure.

[0005] Further, the blowing structure blows hot air into the roller.

[0006] Further, a wind guiding wheel is fixedly arranged in the roller. The wind guiding wheel includes a connecting shaft fixed on the roller and a plurality of wind guiding plates circumferentially and evenly distributed outside the connecting shaft.

[0007] In this solution, the sponge coil is unwound by an unwinding structure and wound up by a winding structure. The sponge sheet passes through each traction and guiding unit in the oven in sequence. In the traction and guiding unit, under the action of two guiding rollers, it is widely wrapped around the drum, except at the blowing structure. The blowing structure is a perforated plate, which is connected to a gas source. There are several air outlet holes on the side of the perforated plate close to the drum. After the air flow flushes the mesh holes of the drum, it enters the drum, passes through the sponge sheet and then enters the oven, and finally is evacuated by the air extraction structure. The air extraction structure is a structure with strip-shaped suction slots and can be connected to an exhaust fan to increase the evacuation intensity. As can be seen from the above, the heating area of the sponge in the oven is relatively large. For an oven of the same length, the effective heating length of the sponge in this solution is longer. In addition, since the drum rotates under the traction of the sponge sheet, the air flow is in a "flung outward" state outside the drum, which improves the efficiency of the air flow passing through the sponge sheet. The flow direction of the air flow outside the drum is more diverse, the residence time of the air flow in the oven is longer, and the heat utilization is higher. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] The following are specific embodiments of the present invention and in combination with the accompanying drawings, the technical solutions of the present invention will be further described, but the present invention is not limited to these embodiments.

[0012] Embodiment 1

[0013] As Figure 1 and Figure 2 shown in the automotive interior sponge deodorizing device, which includes an oven 1, an unwinding structure at one end of the oven 1, and a winding structure at the other end of the oven 1. A plurality of traction and guiding units are arranged in the oven 1. The traction and guiding unit includes a drum 2 rotatably connected in the oven 1, a blowing structure 3, and an air extraction structure 4. The blowing structure 3 is located at the top of the oven 1 directly above the drum 2, and the air extraction structure 4 is located at the top of the oven 1 behind the drum 2. The traction and guiding unit further includes two guiding rollers 5 respectively rotatably connected on both sides of the blowing structure 3; the drum 2 is a mesh structure.

[0014] A wind guiding wheel is fixedly arranged inside the drum 2. The wind guiding wheel includes a connecting shaft fixed on the drum 2 and a plurality of wind guiding plates 6 circumferentially and evenly distributed outside the connecting shaft.

[0015] In this solution, the sponge coil is unwound by an unwinding structure and wound up by a winding structure. The sponge sheet passes through each traction and guiding unit in the oven 1 in sequence. In the traction and guiding unit, under the action of two guiding rollers 5, it is widely wrapped around the drum 2, except at the blowing structure 3. The blowing structure 3 is a perforated plate which is connected to a gas source. On the side of the perforated plate close to the drum 2, there are several air outlet holes. The air flow flushes the mesh holes of the drum 2 and then enters the drum 2. After passing through the sponge sheet, it enters the oven 1 and is finally evacuated by the air extraction structure 4. The air extraction structure 4 is a structure with strip-shaped suction slots and can be connected to an exhaust fan to increase the evacuation intensity. As can be seen from the above, the heating area of the sponge in the oven 1 is relatively large. For the oven 1 of the same length, the effective heating length of the sponge in this solution is longer. In addition, since the drum 2 rotates under the traction of the sponge sheet, the air flow is in a "flinging outward" state outside the drum 2, which improves the efficiency of the air flow passing through the sponge sheet. The flow direction of the air flow outside the drum 2 is more diverse, the residence time of the air flow in the oven 1 is longer, and the heat utilization is higher.

[0016] In this way, the air flow escaping from the inside of the drum 2 to the outside of the drum 2 is more uniform under the action of the air guiding plate 6, and the odor removal effect on the sponge sheet is better.

[0017] Embodiment 2

[0018] This solution is generally the same as that of Embodiment 1, except that: the blowing structure 3 blows hot air into the drum 2, and directly uses the method of blowing hot air into the drum 2 to heat and wash the sponge coil. Compared with Embodiment 1, its structure is simpler.

[0019] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the art to which the present invention pertains can make various modifications or supplements to the described specific embodiments or use similar methods for substitution, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
