Description

Technical Field

[0001] This utility model relates to the field of impregnation technology, and in particular to a continuous impregnation device. Background Technology

[0002] For workpieces such as motor coils, iron cores, and transformers, which require impregnation and drying, impregnation equipment is mainly used.

[0003] Therefore, the applicant previously filed a utility model application with publication number CN 209049653U, which describes an environmentally friendly impregnation equipment. This equipment mainly moves the material frame by horizontally moving and lifting the cylinder head. However, this equipment still has the following drawbacks: 1. The cylinder head and the material frame need to perform hooking and unhooking operations, which makes the overall operation relatively complex and inefficient; 2. This impregnation equipment is suitable for a large number of workpieces, where the workpieces are placed in the material frame and the entire process is completed in one go. However, when the amount of workpieces to be impregnated is small, the equipment requires additional hooking and unhooking operations in addition to the impregnation time, resulting in even lower overall efficiency. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a continuous impregnation equipment that can complete the impregnation requirements of workpieces more quickly, simplify the impregnation process, and improve the impregnation efficiency.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: a continuous impregnation equipment, including an impregnation device and a drying device disposed downstream of the impregnation device. A feeding device is disposed upstream of the impregnation device, and a discharging device is disposed downstream of the drying device. The impregnation device includes an impregnation frame, on which a first impregnation circulating conveyor chain and a second impregnation circulating conveyor chain are mounted. The first and second impregnation circulating conveyor chains are located on both sides of the frame and are driven by an impregnation circulating drive device. Each link of the first and second impregnation circulating conveyor chains has a support wheel on its outer side for support. Each support wheel works together to form a support structure. A suspension frame is placed on the upper horizontal section of the first and second impregnation circulation conveyor chains. A workpiece is suspended at the bottom of the suspension frame. A positioning device is provided on the impregnation frame to position and stop the suspension frame at the impregnation station. An impregnation cylinder cover is installed on the impregnation frame at the impregnation station. The impregnation cylinder cover is located above the suspension frame. An impregnation cylinder body adapted to the impregnation cylinder cover is located below the suspension frame at the impregnation station. The impregnation cylinder body is driven to rise by a lifting power device to seal the impregnation cylinder body and the impregnation cylinder cover with the suspension frame. A vacuuming device is provided on the impregnation cylinder body.

[0006] As a preferred embodiment, the suspension frame is a frame structure, comprising a frame body located between the first and second impregnation circulation conveying chains. The upper and lower surfaces of the frame body are respectively sealed to the impregnation cylinder cover and the impregnation cylinder body. Support plates are provided on both sides of the frame body, and support wheels support the bottom of the support plates.

[0007] As a preferred embodiment, the bottom of the impregnation tank cover and the top of the impregnation tank body are provided with an annular sealing ring.

[0008] As a preferred embodiment, the positioning device includes a first positioning mechanism and a second positioning mechanism with identical structures, and the first positioning mechanism and the second positioning mechanism are respectively positioned and cooperate with the support plates on both sides of the frame body.

[0009] As a preferred embodiment, the first positioning mechanism includes a telescopic positioning rod telescopically mounted on the impregnation machine frame. The telescopic positioning rod telescopically extends from the side of the support plate or from the top of the support plate and positions itself in conjunction with the support plate. The telescopic positioning rod is driven by a telescopic power device.

[0010] As a preferred embodiment, the first positioning mechanism includes a detection bracket fixed on the impregnation machine frame, and a proximity switch is provided on the detection bracket. The proximity switch is electrically connected to the controller of the impregnation cycle drive device.

[0011] As a preferred embodiment, the paint dipping cylinder cover is fixed on the paint dipping machine frame or is vertically and slidably installed on the paint dipping machine frame, and the paint dipping cylinder cover is driven by a cylinder cover lifting power device.

[0012] As a preferred embodiment, the drying device includes a drying chamber, with an inlet and an outlet respectively located at the upstream and downstream ends of the drying chamber. A first drying circulation conveyor chain and a second drying circulation conveyor chain are installed inside the drying chamber. The first and second drying circulation conveyor chains have the same structure as the first and second impregnation circulation conveyor chains and are interconnected. An inlet gate and an outlet gate are respectively provided at the upstream and downstream ends to close or open the inlet and outlet. A heating device is installed inside the drying chamber.

[0013] After adopting the above technical solution, the effect of this utility model is as follows: A first and a second impregnation circulation conveyor chain are installed on the impregnation frame. These chains are located on both sides of the frame and are driven by an impregnation circulation drive device. Each link of the first and second impregnation circulation conveyor chains has a support wheel on its outer side. These support wheels cooperate to form a support structure. A suspension frame is placed on the upper horizontal section of the first and second impregnation circulation conveyor chains, and a suspension device is suspended at the bottom of the suspension frame. The workpiece is mounted on a coating frame equipped with a positioning device that positions the suspension frame at the coating station. A coating tank cover is installed on the coating frame at the coating station, positioned above the suspension frame. A coating tank body, compatible with the coating tank cover, is located below the suspension frame at the coating station. The coating tank body is lifted by a lifting power device to seal the coating tank body and coating tank cover with the suspension frame. A vacuum device is installed on the coating tank body. Therefore, this coating device can directly hang the workpiece to be coated on the suspension frame, and then the suspension frame is directly fed by the first coating circulation conveyor chain and... The support wheels on the second impregnation cycle conveyor chain support the suspended frame, which is then conveyed. When the suspended frame reaches the impregnation station, it is positioned by the positioning device. At this point, the impregnation tank can rise. During the rise, the upper opening of the impregnation tank contacts the suspended frame, and further rise will cause the suspended frame to rise together. Finally, the impregnation tank and its cover are sealed with the suspended frame. The workpiece is then immersed in the paint inside the impregnation tank. A vacuum device then creates a vacuum impregnation. After impregnation is complete, the impregnation tank descends to its initial position, causing the suspended frame to fall into the first impregnation cycle. On the support wheels of the conveyor chain and the second dip-coating circulation conveyor chain, the workpieces that have been dipped in paint will enter the drying device along with the suspension frame. At this time, the dip-coating station will be freed up to facilitate the dip-coating of the workpieces on the suspension frame that are conveyed later. The entire process can be completed by raising and lowering the dip-coating tank, without the need for hooking and unhooking, thus improving the efficiency of dip-coating. This can improve efficiency for both large and small batch production. In addition, the dip-coating device in this solution has the entire dip-coating and drying process from one end to the other, without the need for the suspension frame to turn, thus reducing the size of the equipment.

[0014] Furthermore, since the suspension frame is a frame structure, the suspension frame includes a frame body located in the area between the first and second impregnation circulation conveyor chains. The upper and lower surfaces of the frame body are respectively sealed to the impregnation cylinder cover and the impregnation cylinder body. Support plates are provided on both sides of the frame body, and support wheels support the bottom of the support plates. Therefore, the suspension frame structure is reasonable, using the frame body to suspend various different workpieces, while the support plates on both sides of the frame body are used for support. In this way, both conveying and sealing can be satisfied at the same time.

[0015] Furthermore, since the impregnation cylinder cover is fixed on the impregnation machine frame or is vertically and slidably installed on the impregnation machine frame, and the impregnation cylinder cover is driven by the cylinder cover lifting power device, when the impregnation cylinder cover is fixed, the frame body can be simultaneously pushed up by the rising of the impregnation cylinder body to cooperate with the impregnation cylinder cover. When the impregnation cylinder cover is vertically raised and lowered, the impregnation cylinder cover and the impregnation cylinder body can respectively move closer to the frame body for sealing. In this way, the frame body does not need to be separated from the first impregnation circulation conveying chain and the second impregnation circulation conveying chain, so the position of the frame body is more accurate.

[0016] Furthermore, since the drying device includes a drying chamber, with an inlet and an outlet respectively located at the upstream and downstream ends, and a first drying circulation conveyor chain and a second drying circulation conveyor chain installed inside the drying chamber, the first and second drying circulation conveyor chains have the same structure as the first and second impregnation circulation conveyor chains and are interconnected. An inlet gate and an outlet gate are respectively installed at the upstream and downstream ends to close or open the inlet and outlet. A heating device is installed inside the drying chamber. Therefore, during the drying process, the inlet and outlet of this drying device can be completely closed and independent, thereby avoiding heat loss and achieving a better drying effect.

[0024] The present invention will be further described in detail below through specific embodiments.

[0025] like Figures 1 to 5 As shown, a continuous impregnation equipment includes an impregnation device 2 and a drying device 3 located downstream of the impregnation device 2. A feeding device 1 is located upstream of the impregnation device 2, and a discharging device 8 is located downstream of the drying device 3. The impregnation device 2 includes an impregnation frame 21, on which a first impregnation circulating conveyor chain 22 and a second impregnation circulating conveyor chain 23 are mounted. The first and second impregnation circulating conveyor chains 22 and 23 are located on opposite sides of the frame and are driven by an impregnation circulating drive device. The impregnation circulating drive device is an electric motor, which drives the first and second impregnation circulating conveyor chains 22 and 23 in a cyclical manner.

[0026] Each link of the first dip coating circulating conveyor chain 22 and the second dip coating circulating conveyor chain 23 is provided with a support wheel 24 for support, and the support wheels 24 cooperate to form a support structure. In this embodiment, the dip coating frame 21 is also provided with a tensioning mechanism for tensioning the first dip coating circulating conveyor chain 22 and the second dip coating circulating conveyor chain 23. The dip coating frame 21 is also provided with a horizontal straight groove section, and the upper horizontal section of the first dip coating circulating conveyor chain 22 and the second dip coating circulating conveyor chain 23 is located in the horizontal straight groove section, so that the first dip coating circulating conveyor chain 22 and the second dip coating circulating conveyor chain 23 can better support the suspension frame 4.

[0027] A suspension frame 4 is placed on the upper horizontal section of the first dip coating circulation conveyor chain 22 and the second dip coating circulation conveyor chain 23, and a workpiece is suspended at the bottom of the suspension frame 4.

[0028] In this embodiment, the suspension frame 4 is a frame structure, comprising a frame body 41 located between the first impregnation circulation conveying chain 22 and the second impregnation circulation conveying chain 23. The upper and lower surfaces of the frame body 41 are respectively sealed to the impregnation tank cover 5 and the impregnation tank body 6. Support plates 42 are provided on both sides of the frame body 41, and support wheels 24 support the bottom of the support plates 42. The workpiece can be placed in a material frame first, and then the material frame can be suspended on the suspension frame 4. Alternatively, the workpiece can be hooked onto the suspension frame 4 without using a material frame.

[0029] The dipping frame 21 is equipped with a positioning device to position the suspension frame 4 at the dipping station. A dipping tank cover 5 is installed on the dipping frame 21 at the dipping station, positioned above the suspension frame 4. A dipping tank body 6, compatible with the dipping tank cover 5, is located below the suspension frame 4 at the dipping station. The dipping tank body 6 is driven upwards by a lifting power device to seal the dipping tank body 6, the dipping tank cover 5, and the suspension frame 4. A vacuuming device is installed on the dipping tank body 6. Both the lifting power device and the vacuuming device are conventional structures; an X-type lifting machine can be used for the lifting power device.

[0030] The bottom of the paint dipping tank cover 5 and the top of the paint dipping tank body 6 are provided with an annular sealing ring.

[0031] like Figure 3 As shown, the positioning device includes a first positioning mechanism and a second positioning mechanism with identical structures. The first positioning mechanism and the second positioning mechanism are respectively positioned and cooperated with the support plate portions 42 on both sides of the frame body 41.

[0032] In this embodiment, the first positioning mechanism includes a telescopic positioning rod 71 telescopically mounted on the impregnation machine frame 21. The telescopic positioning rod 71 extends and retracts from the side or top of the support plate 42 and positions itself in conjunction with the support plate 42. The telescopic positioning rod 71 is driven by a telescopic power device 72, which can be a cylinder. In this embodiment, it is preferred to extend and retract from the side and position itself in conjunction with the downstream end face of the support plate 42, thereby blocking and positioning the suspension frame 4. The frame body 41 of the suspension frame 4 can be made of a rectangular tube, and the upper and lower end faces of the rectangular tube can be sealed in conjunction with the impregnation tank body 6 and the impregnation tank cover 5.

[0033] Of course, the first positioning mechanism includes a detection bracket fixed on the impregnation machine frame 21, and a proximity switch is provided on the detection bracket. The proximity switch is electrically connected to the controller of the impregnation cycle drive device. In this way, the start and stop of the impregnation cycle drive device are controlled by the detection signal of the proximity switch.

[0034] The paint dipping cylinder cover 5 is fixed on the paint dipping machine frame 21 or the paint dipping cylinder cover 5 is vertically lifted and slidably installed on the paint dipping machine frame 21. The paint dipping cylinder cover 5 is driven by a cylinder cover lifting power device.

[0035] In this embodiment, the paint dipping tank cover 5 is fixed on the paint dipping machine frame 21. When the paint dipping tank cover 5 is vertically lifted and slidably installed, the paint dipping tank cover 5 and the paint dipping tank body 6 will move towards the suspension frame 4 and seal each other.

[0036] The drying device 3 includes a drying chamber, with an inlet and an outlet respectively located at the upstream and downstream ends of the drying chamber. The drying chamber contains a first drying circulation conveyor chain 33 and a second drying circulation conveyor chain. The first drying circulation conveyor chain 33 and the second drying circulation conveyor chain have the same structure as the first impregnation circulation conveyor chain 22 and the second impregnation circulation conveyor chain 23 and are interconnected. The upstream and downstream ends are respectively provided with an inlet gate 31 and an outlet gate 32 to close or open the inlet and outlet. The drying chamber contains a heating device.

[0037] In this embodiment, the feeding device 1 and the unloading device 8 have the same structure and also use a circulating conveyor chain for cyclic conveying. The suspension frame 4 is conveyed by the interconnection of the circulating chains. Of course, the circulating conveyor chain of the feeding device 1 and the unloading device 8 is the same chain as the circulating conveyor chain of the dipping device 2 and the drying device, so they can share a set of conveying power. However, the inlet gate 31 and the outlet gate 32 of the drying device cannot be completely closed, but the entire process of feeding, dipping, drying and unloading can still be realized.

[0038] The working principle in this embodiment is as follows: First, the suspension frame 4 is placed on the circulating chain of the feeding device 1. Then, the workpiece or the material frame containing the workpiece is suspended on the frame body 41. The feeding device 1 then conveys the suspension frame 4 to the first impregnation circulating conveyor chain 22 and the second impregnation circulating conveyor chain 23. The workpiece is then positioned by a positioning device. After positioning, the first impregnation circulating conveyor chain 22 and the second impregnation circulating conveyor chain 23 stop conveying. The impregnation tank 6 and the impregnation tank cover 5 are then sealed with the frame body 41 to achieve vacuum impregnation. After impregnation, the impregnation tank 6 and the impregnation tank cover 5 are separated from the frame body 41. The impregnated workpiece is then moved with the suspension frame 4 to the drying device 3 for drying. After drying, it is directly sent to the unloading device 8 for unloading.

[0039] The above-described embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Any modifications and alterations to the technical solution of the present utility model without departing from its design spirit shall fall within the protection scope defined by the claims of the present utility model.
