However, it should be understood that these descriptions are only for further explaining the features and advantages of the present utility model, rather than limiting the patent requirements of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative work fall within the scope of protection of the present utility model.

[0019] The present utility model will be further described below in conjunction with the drawings and preferred embodiments.

[0020] Embodiment 1

[0021] Referring to Figure 1 and Figure 2 As shown, a heat treatment device for screw production involved in this embodiment includes a heat treatment furnace (not shown), and a blanking device is provided at the furnace opening of the heat treatment furnace;

[0022] The blanking device includes a frame 1. Rotatably connected to the frame 1 are a downwardly inclined active drive link 2 and a driven drive link 3. The driven drive link 3 is arranged parallel to the active drive link 2. An active front drive wheel 4 and an active rear drive wheel 5 that move in a follow-up manner are provided on the active drive link 2. A driven front drive wheel 6 and a driven rear drive wheel 7 that move in a follow-up manner are provided on the driven drive link 3.

[0023] A front wheel rim 8 is provided between the active front drive wheel 4 and the driven front drive wheel 6 and is located above them. The outer wall surface of the front wheel rim 8 is closely attached to the wheel surfaces of the active front drive wheel 4 and the driven front drive wheel 6, and the front wheel rim 8 rotates relative to the active front drive wheel 4 and the driven front drive wheel 6.

[0024] A rear wheel rim 9 is provided between the active rear drive wheel 5 and the driven rear drive wheel 7 and is located above them. The outer wall surface of the rear wheel rim 9 is closely attached to the wheel surfaces of the active rear drive wheel 5 and the driven rear drive wheel 7, and the rear wheel rim 9 rotates relative to the active rear drive wheel 5 and the driven rear drive wheel 7.

[0025] A number of rim connecting rods 10 with one end connected to the front wheel rim and the other end connected to the rear wheel rim are circumferentially arranged between the front wheel rim 8 and the rear wheel rim 9.

[0026] One end of the active drive link 2 is drivingly connected to a power assembly that controls its rotation.

[0027] Further, a blanking channel is formed among the front wheel rim 8, the rear wheel rim 9 and the rim connecting rods 10. The blanking channel has a loading opening 11 and a blanking opening 12. The vertical height of the blanking opening 12 is lower than the vertical height of the loading opening 11.

[0028] Further, a blanking slope plate 13 fixed to the frame 1 is provided at the blanking opening 12.

[0029] Further, a front limiting ring 15 for restricting axial movement is provided on the front wheel rim 8; a rear limiting ring 16 for restricting axial movement is provided on the rear wheel rim 9.

[0030] Further, the power assembly includes an active gear 17, a driven gear 18 and a motor (not shown). The driven gear 18 is drivingly connected to the active drive link 2. The active gear 17 is provided on the output shaft of the motor (not shown), and the active gear 17 meshes with the driven gear 18.

[0031] In this embodiment, the screws that have just completed heat treatment are taken out from the heat treatment furnace and put into the loading opening 11, pass through the blanking channel, and finally are discharged from the blanking opening 12. During this period, the screws contact the air and cool down, and finally are received and collected by a storage frame near the blanking opening 12.

[0032] Since the temperature of the screws taken out from the heat treatment furnace is high and they directly contact the same rim link 10, heat will concentrate here, causing deformation over time. Therefore, during the discharge of the screws, the active drive link 2 rotates. Through the front and rear drive wheels, the front rim 8 and the rear rim 9 rotate relative to each other and drive all the rim links 10 to rotate together, so that during the discharge of the screws, the rim links 10 are continuously switched to use, avoiding deformation due to heat concentration.

[0033] Among them, through the setting of the front limit ring 15, it is used for the axial limit of the front rim 8; through the setting of the rear limit ring 16, it is used for the axial limit of the rear rim 9.

[0036] In this embodiment, through the addition of the fan 14, during the discharge of the screws in the discharge channel, the gas convection can be enhanced, the heat dissipation can be accelerated, and the cooling speed of the screws can be faster.

[0037] The heat treatment device for screw production involved in the present invention realizes the screw cooling function by connecting a discharge device between the heat treatment furnace and the storage frame in series. The discharge device is equipped with a fan to dissipate heat from the passing screws, so that the temperature of the screws entering the storage frame is low, and the storage frame is not easily deformed or damaged. The overall function is perfect and the practicability is strong.
