As shown in fig. 3 to 6, a rotary frame 400 is arranged in the temperature-controlled furnace 100, the rotary frame 400 includes a connecting portion 410, a rotating shaft 420 and two rotating discs 430, in order to reduce weight, each of the two rotating discs 430 is provided with a weight-reducing hole 431, the two rotating discs 430 are arranged at intervals and connected together through the connecting portion 410, and the rotating shaft 420 is arranged at the center of the connecting portion 410. In order to realize the installation of the revolving rack 400, the screw pump stator heat preservation system further comprises a rack 500, the rack 500 is respectively provided with a tripod 510 at the front side and the rear side of the temperature control furnace 100, and two ends of the rotating shaft 420 respectively extend out of the temperature control furnace 100 and are rotatably connected to the two tripods 510 through bearings, so as to realize the rotation of the revolving rack 400 in the temperature control furnace 100. In order to drive the revolving frame 400 to rotate, the revolving shaft 420 is provided with a driving device (not shown in the drawings) outside the temperature-controlled furnace 100, the driving device includes a speed-reducing motor and a remote transmission mechanism, the remote transmission mechanism can be a chain transmission mechanism, and the speed-reducing motor can transmit power to the revolving shaft 420 through the chain transmission mechanism to drive the revolving shaft 420 to rotate.

In other embodiments, the rotating shaft 420 may also be directly and rotatably connected to the temperature-controlled furnace 100 without providing the rack 500, but since the mechanical strength of the temperature-controlled furnace 100 is generally low, this embodiment is only an alternative solution.

Specifically, the two rotating discs 430 are connected with a plurality of hanging baskets 441 through bearings, all hanging baskets 441 can rotate freely and keep vertical to the ground under the action of gravity, all hanging baskets 441 on each rotating disc 430 are circumferentially and uniformly distributed on the corresponding rotating disc 430, at this time, the angle between two adjacent hanging baskets 441 is a division value, all hanging baskets 441 on the two rotating discs 430 are uniformly and correspondingly arranged, every two hanging baskets 441 arranged at intervals jointly form a transit part 440, and the moving path of each transit part 440 is intersected with the feeding unit 200 and the discharging unit 300, so that the rotary frame 400 is butted with the feeding unit 200 and the discharging unit 300.

Further, in order to avoid interference between the transfer part 440 and the feeding unit 200 and the discharging unit 300, the widths of the two conveying units are smaller than the length of the stator, that is, both ends of the stator can extend out of the two conveying units, and all the hanging baskets 441 are located outside the two conveying units, so that the transfer part 440 can take over the stator extending out of the feeding unit 200 and smoothly lower the stator to the discharging unit 300.

It should be further noted that, because the screw pump stator can adopt a production line type injection molding process, the discharge timing of each stator is different, if the conventional heat preservation process is adopted, a plurality of stators need to be collected and sent into the furnace together for heat preservation, and although the heat preservation time of all the stators in the furnace is consistent, the respective shrinkage rates are different, and defective products are very easy to occur. The utility model discloses except can realizing carrying out the butt joint with the production water line of stator, can also ensure that every stator all has the same processing parameter to promote the processingquality of stator.

As shown in fig. 1, 3, 5 and 6, in some embodiments of the present invention, since the stator needs to be kept in the temperature control furnace 100 for a certain period of time, and the conventional reduction motor cannot satisfy the reduction ratio, the intermittent rotation of the turret 400 can be realized by using an intermittent transmission manner. To this end, the driving device is provided with a clutch 600, the clutch 600 includes a first clutch gear 610 and a second clutch gear 620 which are capable of engaging with each other, one of the first clutch gear 610 and the second clutch gear 620 is fixedly connected to the rotating shaft 420, and the other of the first clutch gear 610 and the second clutch gear 620 is fixedly connected to the driven wheel of the remote transmission mechanism.

Further, since the turret 400 can still rotate under the inertia effect after the clutch 600 is switched to the off state, in order to limit the rotation of the turret 400 and prevent the rotation from disturbing the production cycle, the brake disc 700 is mounted on the end of the rotating shaft 420 far away from the driving device. When the clutch 600 is switched to the off state, the controller activates the brake disc 700 to define the position of the turret 400, and when the clutch 600 is switched to the on state, the brake disc 700 is switched to the standby state.

The baffle 220 can define the position of the stator, and since the position of the baffle 220 is adjustable, after the installation or maintenance, the specific position of the stator on the feeding unit 200 can be defined by adjusting the position of the baffle 220, so that the stator can be accurately butted with the transfer part 440.

Further, in order to facilitate observing the butt joint condition between the transit part 440 and the stator, the temperature-controlled furnace 100 is provided with observation windows (not shown in the drawings) at corresponding positions of the feeding unit 200 and the discharging unit 300, respectively, and the observation windows may be acrylic plates.

As shown in fig. 4, 7 and 8, in some embodiments of the present invention, in order to prevent the stator from rolling off during rotation, a positioning groove 4411 is provided at the bottom of each hanging basket 441, wherein the positioning groove 4411 can be selected as a V-shaped groove or an arc-shaped groove, and the positioning groove 4411 can define the relative position between the middle rotating portion 440 and the stator.

2. when the transfer part 440 drives the stator to rise to a designated height, that is, after the second inductive sensor 900 detects the detection position 810 of the index plate 800, the controller controls the clutch 600 to switch to the "off" state, at this time, the driving device idles, and the brake disc 700 locks the rotation of the rotating shaft 420, and at the same time, the other transfer part 440 lowers the stator after heat preservation to the discharging unit 300;
