Description

Technical Field

[0001] The utility model mainly relates to the technical field of drying, and in particular to a drying device for workpieces conveyed by an accumulation and release chain. Background Art

[0002] Oven is a common equipment used in industry to dry workpieces. Oven is widely used in precision baking, drying and shaping processing of optoelectronics, electronics, motors, communications, electroplating, plastics, mechanical equipment, etc.

[0003] In some scenarios, the oven is often used in conjunction with an accumulation chain. The accumulation chain is passed through the interior of the oven, and the workpiece is lifted by the accumulation chain for transportation, and dried when passing through the oven during transportation. For example, after the workpiece is cleaned or painted on the surface of the workpiece, the workpiece is hung on the accumulation chain and transported in sequence, and the surface of the workpiece can be dried when passing through the oven. However, when using existing ovens, it is usually necessary to manually open or close the doors on both sides, and it is inconvenient to selectively control the degree of opening of the door according to the size of the transported workpiece. If the door is opened too small, it is inconvenient for the workpiece to pass through the oven. If the door is opened too large, it is not conducive to the drying effect of the oven, and it is inconvenient to use. Therefore, it is necessary to propose an improvement measure to solve the above technical problems.

[0004] It should be noted that the above contents belong to the technical cognition scope of the inventor. Since the technical contents in this field are vast and too complicated, the above contents of this application do not necessarily constitute prior art. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. Example

[0026] See attached Figure 1-3 The utility model of this embodiment is a workpiece drying device with a stacking chain, comprising an oven 1, wherein a stacking chain 7 passes through the upper middle part of the oven 1. Two doors 2 are slidably mounted on both sides of the oven 1, and a driving mechanism is correspondingly arranged on the top of the outer side of the oven 1, through which the two doors 2 on both sides of the oven 1 can be synchronously moved inwards to close or moved outwards to open.

[0027] Specifically, the driving mechanism includes a double-headed telescopic cylinder 3, which is correspondingly installed at the middle position of the outer top of the oven 1 body. The ends of the telescopic rods on both sides of the double-headed telescopic cylinder 3 are rotatably installed with two connecting rods 4. The two connecting rods 4 on one side of the double-headed telescopic cylinder 3 are respectively rotatably connected to the tops of the two doors 2 on one side of the oven 1 body, and the two connecting rods 4 on the other side of the double-headed telescopic cylinder 3 are respectively rotatably connected to the tops of the two doors 2 on the other side of the oven 1 body.

[0028] The top and bottom ends of both sides of the oven 1 are provided with corresponding slide grooves 101, and two doors 2 are slidably installed in the slide grooves 101. The two doors 2 are symmetrically arranged on the front and rear sides and slide through the front and rear sides of the oven 1; the top of the slide groove 101 on the top of the oven 1 is provided with a strip-shaped notch 102, and the inner side of the top of the door 2 is provided with a connecting block 5, which slides through the notch 102, and the top of the connecting block 5 is provided with a hinge block 6, which is rotatably connected to one end of the connecting rod 4.

[0029] The oven 1 has strip holes 103 on both sides of the upper slide 101. The shape and size of the strip holes 103 correspond to the shape and size of the cross section of the door 2. The two doors 2 in the slide 101 slide through the strip holes 103 on both sides.

[0030] The double-head telescopic cylinder 3 and the accumulation chain 7 are both existing equipment. The accumulation chain 7 can be used to lift and transport the workpiece, and dry it when it passes through the oven 1 during transportation. This embodiment only improves the door 2 on both sides of the oven 1. The internal structure of the oven 1 and its working principle are basically the same as those of the existing oven, that is, a circulating air supply system is correspondingly provided in the oven 1. The air source is driven by the circulating air supply motor to drive the wind wheel to send hot air through the heater, and then through the air duct to one side of the inner chamber of the oven 1, and then the used air is sucked into the air duct on the other side of the inner chamber of the oven 1, and becomes the air source for recirculation and heating. Since the above contents about the internal structure and working principle of the oven 1 are existing technologies, this embodiment will not be elaborated in detail.

[0031] When in use, according to the transverse size of the workpiece transported on the accumulation chain 7, the telescopic distance of the telescopic rods on both sides of the double-headed telescopic cylinder 3 is controlled to synchronously control the opening degree of the door 2 on both sides of the oven 1, so that the opening degree of the door 2 on both sides of the oven 1 is slightly larger than the transverse size of the workpiece, and the opening degree of the door 2 on both sides of the oven 1 is kept consistent, so that the workpiece passing through can be dried. The top of the outer wall on both sides of the oven 1 where the door is installed is provided with size scales so that the staff can observe the opening size of the door 2 with the naked eye. The double-headed telescopic cylinder 3 can be electrically connected to an external control system so that automatic regulation can be performed.

[0032] The above-described embodiments only express a certain implementation method of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the patent of the utility model shall be based on the attached claims.
