DETAILED DESCRIPTION

[0034] In order to more clearly understand the technical means of the utility model and implement it according to the contents of the specification, the specific implementation methods of the utility model are further described in detail below in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0035] like Figure 1 As shown, the utility model discloses an automatic feeding device for heat treatment equipment, comprising a peripheral conveyor 1 and a conveyor line 2 for conveying the peripheral conveyor 1. The peripheral conveyor 1 is provided in multiple groups for carrying the parts to be heat treated. The feeding end of the conveyor line 2 is provided with a lifting and feeding mechanism, and the lifting and feeding mechanism comprises a lifting frame 3, a running track 4 provided on the lifting frame 3, and a lifting box 5 whose travel is along the running track 4. The peripheral conveyor 1 is transferred to the lifting box 5 through the conveyor line 2. The lifting box 5 is driven by a driving device to slide and transfer the peripheral conveyor 1 carrying the parts to be heat treated to the lifting and feeding position along the running track 4. The driving device can be a hydraulic cylinder device, which has a simple structure and reliable operation.

[0036] Specifically, Figures 2 to 3The operating rails 4 are provided with two groups, and the two groups of operating rails 4 are symmetrically arranged on the opposite inner sides of the lifting frame 3. The operating rails 4 include an inner rail 41 and an outer rail 42. A smooth curved portion 43 is provided at the neck position above the inner rail 41, and a bending portion 44 is provided at the neck position above the outer rail 42. The outer rail 42 is connected to the bending portion 44 through an arc.

[0037] like Figures 4 to 6 As shown, the lifting box 5 is provided with an opening 51 facing the conveyor line 2, and the peripheral carrier 1 moves into the lifting box 5 through the opening 51. Sliding shafts 52 cooperating with the operating track 4 are provided on both sides of the lifting box 5, and the sliding shafts 52 are slidably connected to the operating track 4.

[0038] The upper end of the lifting box 5 is a discharge port 53, and the end of the discharge port 53 away from the opening 51 is higher than the end of the discharge port 53 located at the opening 51, and the two opposite sides of the lifting box 5 are located at the discharge port 53 to form an inclined triangle, and the discharge port 53 is abutted against an inclined lifting box cover 54, and the end of the lifting box cover 54 close to the opening 51 is hinged to the lifting box 5, and the free end of the lifting box cover 54 away from the opening 51 is formed with a bent side panel 55 to form a covering of the discharge port 53 by the lifting box cover 54 and the side panel 55.

[0039] During operation, the driving device drives the lifting box 5 to move upward to the lifting loading position, and the sliding shaft 52 in the inner track 41 slides to the curved portion 43, turning from the upward movement state to the horizontal slow movement state, and the sliding shaft 52 in the outer track 42 takes the sliding shaft 52 in the inner track 41 as the center, continues to move upward along the outer track 42 and slides into the curved portion 44, so that the lifting box 5 flips along the sliding shaft 52 in the inner track 41, and the peripheral transport tool 1 flips accordingly, and the sliding shaft 52 in the outer track 42 continues to move along the curved portion 44 until the parts to be heat treated are poured out from the discharge port 53 under the action of gravity.

[0040] Furthermore, the lifting box 5 is provided with a hydraulic drive device for controlling the opening and closing degree of the lifting box cover 54. The stroke output end of the hydraulic drive device is fixedly connected to the lifting box cover 54 to prevent a large number of parts to be heat treated from being dumped out of the peripheral transport tool 1 at the same time, causing collisions and damage between the parts to be heat treated.

[0041] Furthermore, a limiter 56 is provided on the lifting box 5, and the limiter 56 is located above the peripheral transport tool 1 to control the position of the peripheral transport tool 1 in the lifting box 5 to prevent the peripheral transport tool 1 from contacting the lifting box cover 54 during the pouring process of the parts to be heat treated.

[0042] A first hopper 6 and a second hopper 7 are sequentially provided in the discharge direction of the discharge port 53. Both the first hopper 6 and the second hopper 7 are provided with vibration devices. The parts to be heat treated are poured out from the discharge port 53 and fall into the first hopper 6. The vibration device of the first hopper 6 can make the parts to be heat treated fall evenly into the second hopper 7, and then the vibration device of the second hopper 7 can achieve even discharge.

[0043] Specifically, an inclined discharge plate 8 is provided below the discharge port 53. After the parts to be heat treated are poured out from the peripheral conveyor 1, they fall on the upper end of the discharge plate 8, and then slide from the upper end of the discharge plate 8 to the first hopper 6 at the lower end of the discharge plate 8. The discharge plate 8 is inclined to buffer the parts to be heat treated, so as to prevent the parts to be heat treated from being directly poured out from the peripheral conveyor 1 into the first hopper 6, causing direct impact on the first hopper 6; at the same time, the side plate 55 at the free end of the lifting box cover 54 also plays a buffering role for the parts to be heat treated; this structure prolongs the service life of the first hopper 6.

[0044] Furthermore, a baffle plate 61 is provided on the first hopper 6 to prevent the parts to be heat-treated from directly rolling into the second hopper 7 during the process of being poured out from the discharge port 53 .

[0045] Furthermore, the second hopper 7 is provided with a plurality of groups of material-blocking columns 71, which are cylindrical rod structures. The gaps between the material-blocking columns 71 are adjusted according to the specifications and shapes of the parts to be heat treated. In particular, slender parts to be heat treated are prone to entanglement during transportation, resulting in poor material discharge. The gaps between the material-blocking columns 71 are increased and uniform material discharge is achieved through a vibration device.

[0046] In this embodiment, a quality monitoring unit is further provided above the first hopper 6, and the quality monitoring unit is used to monitor the weight of the remaining parts to be heat treated in the first hopper 6, and the discharge frequency is controlled by monitoring the weight of the remaining parts to be heat treated.

[0047] Specifically, it also includes a control system. The driving device and the quality monitoring unit are both electrically connected to the control system. Through the signal fed back by the quality monitoring unit, the control system controls the unloading interval time of the peripheral conveyor 1 through the driving device, thereby achieving isolation between heat treatment batches and reducing the risk of mixing.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the technical principle of the present invention, and these improvements and modifications should also be regarded as within the protection scope of the present invention.
