[0027] The embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0028] As shown in Figures 1-7 The present application provides a rotary feeder, which comprises a furnace body 1, a support seat 20 fixedly installed on the upper part of the furnace body 1, a rotary pouring mechanism arranged on the support seat 20, and a transfer mechanism arranged on one side of the support seat 20. In one embodiment, the rotary pouring mechanism comprises an electric rotating table 24 fixedly installed on the support seat 20, a bearing plate 25 fixedly connected to the output end of the electric rotating table 24, and two positioning assemblies arranged symmetrically along the bearing plate 25; a pouring core 10 is fixedly installed on the furnace body 1 corresponding to one of the positioning assemblies; the transfer mechanism comprises a fixed frame 30 fixedly installed on the support seat 20, a driving motor 31, and an execution assembly driven by the driving motor 31; the execution assembly comprises a movable frame 37 and a suction cup 371 installed on the bottom of the movable frame 37; a horizontal moving mechanism is arranged on the fixed frame 30, and the movable frame 37 is slidingly connected to the horizontal moving mechanism to move horizontally back and forth; the driving motor 31 is connected with a lifting driving mechanism through a transmission mechanism, and the lifting driving mechanism is connected with the movable frame 37 to drive the movable frame 37 to move up and down; the movement trajectory of the suction cup 371 passes through one of the positioning assemblies and a feeding and discharging station outside the bearing plate 25 in sequence.

[0029] In this embodiment, the two positioning assemblies on the bearing plate 25 are respectively in "pouring station" and "transfer station", and the positioning assembly in the pouring station completes the pouring work below the pouring core 10; at the same time, the driving motor 31 is started, and the movable frame 37 and the suction cup 371 on the bottom thereof are driven to move along a preset trajectory through the cooperation of the transmission mechanism and the lifting driving mechanism, which first moves the suction cup 371 horizontally above the positioning assembly in the transfer station, then descends to adsorb the finished product in the station which has completed pouring, then rises and moves horizontally to the feeding and discharging station outside the bearing plate 25 to put down the finished product, and when one side of the work is completed, the electric rotating table 24 drives the bearing plate 25 to rotate one hundred and eighty degrees to exchange the two stations, so as to start a new round of parallel pouring and taking and placing cycle, and realize continuous automatic production.

[0030] In one embodiment, the positioning assembly comprises a plurality of positioning bowls 26 slidingly arranged in the bearing plate 25, and a cylinder 21 fixedly arranged on the support base 20 corresponding to each positioning bowl 26, and a water-cooled pressure head 22 fixedly connected to the output end of the cylinder 21, and a fixed plate 252 fixedly connected to the outer wall of the positioning bowl 26, and a sliding rod 251 slidingly connected to the bearing plate 25 and fixedly connected to the fixed plate 252, and a first spring 253 sleeved on the sliding rod 251, and a limiting plate 254 fixedly connected to one end of the sliding rod 251, and the first spring 253 fixedly connected at both ends to the bearing plate 25 and the limiting plate 254; the bottom of the positioning bowl 26 is internally arranged for accommodating the filter gauze asbestos 28 and the gypsum mold 27, and the pouring core 10 is arranged with a core head 11, and the bottom of the positioning bowl 26 is arranged with a through hole 261 for the core head 11 to be inserted.

[0031] In this embodiment, the positioning bowl 26 is in the initial high position under the pre-tightening force of the first spring 253, and the filter gauze asbestos 28 and the gypsum mold 27 have been placed inside, when the positioning assembly rotates to the pouring station, the cylinder 21 above is started, pushing the water-cooled pressure head 22 to move downward, the water-cooled pressure head 22 contacts and presses the positioning bowl 26, overcoming the elastic force of the first spring 253, pushing the entire positioning bowl 26 assembly to move downward, in this process, the core head 11 below the pouring core 10 is inserted into the through hole 261 at the bottom of the positioning bowl 26, and the filter gauze asbestos 28 and the gypsum mold 27 inside are lifted upward until the top thereof contacts the water-cooled pressure head 22 and the bottom thereof contacts the core head 11, so as to be limited and compressed in the vertical direction, forming a sealed pouring cavity; after pouring is completed, the cylinder 21 retracts the water-cooled pressure head 22, and the positioning bowl 26 is reset upward under the restoring force of the first spring 253, and is separated from the core head 11, preparing for subsequent rotation to move out of the station.

[0032] In one embodiment, the support base 20 is further arranged with a control box 12 and a water-cooled machine 23, and the water-cooled machine 23 is connected to the water-cooled pressure head 22 through a pipeline. The horizontal moving mechanism comprises a fixed rod 361 horizontally fixed to the fixed frame 30, a sliding sleeve 362 slidingly sleeved on the fixed rod 361, and a movable rod 363 vertically fixed to the sliding sleeve 362; the movable frame 37 is slidingly sleeved on the movable rod 363. The transmission mechanism comprises a driving wheel 311 fixedly connected to the output end of the driving motor 31, and a first connecting arm 34 coaxially fixedly connected to the driving wheel 311; the first connecting arm 34 is rotationally connected to the vertical plate 32 fixedly arranged on one side of the fixed frame 30 through a first rotating shaft; the lifting driving mechanism comprises a movable arm 33 rotationally connected to the vertical plate 32, and a first sliding groove 331 arranged on the movable arm 33; the free end of the first connecting arm 34 is slidingly connected to the first sliding groove 331 through a sliding block 332.

[0033] In the embodiment, the control box 12 is used to coordinate the actions of the electric rotary table 24, the driving motor 31, the cylinder 21 and other execution elements. The movement source of the transfer mechanism is the driving motor 31. The motor 31 drives the driving wheel 311 and the first connecting arm 34 coaxial with the driving wheel 311 to make continuous rotary movement. The slider 332 at the end of the first connecting arm 34 slides in the first sliding groove 331. Since the first sliding groove 331 is arranged on the movable arm 33 which can rotate around the hinge point, the rotary movement of the first connecting arm 34 is converted into the reciprocating swing of the movable arm 33 around the hinge point with the vertical plate 32. The swing of the movable arm 33 is the output movement, which is used to drive the subsequent mechanism. Meanwhile, the movable frame 37 is guided to move horizontally through the sliding fit between the sliding sleeve 362 and the fixed rod 361, and is guided to move up and down through the sliding fit with the movable rod 363.

[0034] In one embodiment, the second sliding groove 333 is further arranged on the movable arm 33. The second connecting arm 35 is rotatably connected with the second sliding groove 333 through the slider 332. The other end of the second connecting arm 35 is rotatably connected with the plate body 39 fixedly arranged on the fixed frame 30 through a second rotating shaft. The second rotating shaft is fixedly connected with the movable plate 38. The rod body 381 is slidably connected with the movable plate 38 along the length direction of the movable plate 38. One end of the rod body 381 is rotatably connected with the movable frame 37 through the connecting seat 382. The second spring 383 is sleeved on the rod body 381. The two ends of the second spring 383 are fixedly connected with the connecting seat 382 and the movable plate 38 respectively.

[0035] In the embodiment, when the movable arm 33 swings, the second sliding groove 333 on the movable arm 33 drives the second connecting arm 35 to move through the internal slider 332. The second connecting arm 35 pulls or pushes the movable plate 38 hingedly connected with the other end of the second connecting arm 35, so that the movable plate 38 reciprocates within a certain angle around the second rotating shaft with the plate body 39. The rotation of the movable plate 38 acts on the movable frame 37 through the rod body 381. The rod body 381 and the movable plate 38 are slidable and connected through the second spring 383. When the movable plate 38 rotates, the rod body 381 and the movable frame 37 first generate horizontal component movement. The movable frame 37 slides along the fixed rod 361 through the sliding sleeve 362. When the horizontal movement is about to stop due to the mechanism constraint, such as the sliding sleeve 362 reaching the end point of the fixed rod 361 or the movable frame 37 contacting the constraint on the side surface, the continuous rotation of the movable plate 38 will compress or stretch the second spring 383, and the spring force will be converted into the component movement of driving the movable frame 37 to move up and down along the movable rod 363. Through the design of the sizes and hinge point positions of the first connecting arm 34, the movable arm 33, the second connecting arm 35 and the movable plate 38, the movable frame 37 can sequentially complete the horizontal right movement, vertical downward movement, vertical upward movement and horizontal left movement in a complete swing cycle of the movable arm 33, so that the suction cup 371 accurately performs the preparation actions of taking the workpiece from the transfer station, moving to the outside station to place the workpiece and returning.

[0036] In one embodiment, a driven wheel 312 is also mounted on the support base 20, and the driving wheel 311 drives the driven wheel 312 to rotate synchronously through a belt 313; the driven wheel 312 is connected with the same auxiliary transfer mechanism as the transfer mechanism.

[0037] In the embodiment, the driving motor 31 transmits power to another auxiliary transfer mechanism at constant speed and in phase through the synchronous transmission system composed of the driving wheel 311, the belt 313 and the driven wheel 312; when the movable frame 37 of the main transfer mechanism performs the taking and placing cycle, the movable frame 37 of the auxiliary transfer mechanism performs completely synchronous movement; in the actual layout, the two transfer mechanisms can serve different positioning assemblies on the bearing plate 25 or different workstations on the production line, so that the taking out of multiple finished products and the placing of new molds can be completed simultaneously within one production beat, thereby making the production capacity of the equipment almost doubled.

[0038] When the present application works: first, the positioning assembly at the pouring station performs the pouring work, and the corresponding cylinder 21 is started to push the water-cooled pressure head 22 to press down, so that the positioning bowl 26 moves downward against the elastic force of the first spring 253, the gypsum mold 27 and the filter screen asbestos 28 in it are lifted upward and pressed tightly by the core head 11 below, forming a sealed cavity for pouring, and the electric rotary table 24 is started to drive the bearing plate 25 to rotate 180 degrees, at the same time, the main transfer mechanism starts to act; Then, the driving motor 31 in the main transfer mechanism drives the movable frame 37 and the suction cup 371 to move along the preset trajectory through the driving and lifting driving mechanism, the driving wheel 311, the first connecting arm 34 and the movable arm 33, etc.; the suction cup 371 first moves horizontally to the top of the positioning bowl 26 at the transfer station, and then descends to adsorb the finished product in the station which has completed pouring and cooling.

[0039] Then, the suction cup 371 adsorbs the finished product, rises and moves horizontally to the fixed feeding and discharging station outside the bearing plate 25 to release the finished product; immediately, the auxiliary transfer mechanism starts to work, which is synchronously driven by the same driving motor 31 through the belt 313 and the driven wheel 312, and the movable frame 37 thereof performs a completely synchronous movement trajectory with the main transfer mechanism; when the main transfer mechanism moves out the finished product, the suction cup 371 of the auxiliary transfer mechanism has picked up a new filter screen asbestos 28 and gypsum mold 27 from the standby area and moved to the top of the positioning bowl 26 at the transfer station, and then descends to accurately place the new mold assembly into the empty positioning bowl 26; The original pouring station rotates to the transfer station, and the station with the new mold placed therein rotates to the pouring station, and the equipment enters the next same cycle.

[0040] The above merely illustrates the specific embodiments of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art can easily think of various changes or replacements within the technical range disclosed by the present application, which should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
