[0037] To make the technical solutions and technical effects of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model.

[0038] The utility model aims to provide a swinging device for an extruder used in sealant production, so as to solve the problem that only one receiving barrel can be used to collect the glue material at the glue discharging port of the current extruder. Refer to Figure 1 , the swinging device mainly includes a device body 00, and the device body 00 is arranged at the glue discharging port of the extruder 01 to throw the discharged glue material into the receiving barrel 02. The device body 00 mainly includes a transition barrel 10, a discharging barrel 20, a driving mechanism and a positioning mechanism, which are specifically introduced as follows:

[0039] Regarding the transition barrel 10: In this embodiment, the transition barrel 10 is the reference part of the device body 00. The transition barrel 10 is coaxially arranged with the glue discharging port of the extruder 01. Refer to Figure 5 , a fixing plate 11 is arranged on the contact surface between the transition barrel 10 and the glue discharging port. The fixing plate 11 is fixed to the contact surface of the glue discharging port by bolts, and it is ensured that the coaxiality between the transition barrel 10 and the extruder 01 is within 0.04 mm. Through holes for fixing the driving mechanism are provided on the side surface of the fixing plate 11. A sealing ring groove 311 for cooperating with the sun gear assembly 31 is arranged on the outer circumference of the transition barrel 10.

[0040] Regarding the discharging barrel 20: The discharging barrel 20 is vertically arranged at one end of the transition barrel 10 far from the extruder 01, and the discharging barrel 20 is communicated with the transition barrel 10 and the glue discharging port. Refer to Figure 2 , the discharging barrel 20 can make a pendulum movement relative to the transition barrel 10 to throw the discharged glue material into the receiving barrels 02 at different positions;

[0041] Regarding the driving mechanism: Refer to Figures 3-4 , the driving mechanism includes a planetary gear 32 and a sun gear assembly 31 coaxially arranged with the transition barrel 10. The planetary gear 32 can drive the sun gear assembly 31 to rotate to drive the discharging barrel 20 to make a pendulum movement. Refer to Figure 6, the outer circumference of the sun gear assembly 31 has a sun gear 310 that meshes with the planetary gears 32. The sun gear 310 is an important component of the swinging device. At least three planetary gears 32 are evenly distributed along the circumferential direction of the sun gear 310. Preferably, three planetary gears 32 are equally divided along the circumferential direction of the sun gear 310, so that both the driving rotation action and stability are achieved. The driving mechanism further includes a servo motor 34 and a driving gear 33. The servo motor 34 is fixed on the top of the fixing plate 11. The servo motor 34 can provide different rotational speed values according to the production requirements. A driving gear 33 is arranged on the side of the servo motor 34 close to the sun gear assembly 31. The driving gear 33 meshes with one of the planetary gears 32 to form a driving wheel, and the remaining planetary gears 32 are driven wheels. The driving wheel is used to transmit power, and the remaining driven wheels play a role in auxiliary transmission and coaxiality maintenance, that is, the driving wheel drives the sun gear 310 to rotate and drives the driven wheels to rotate. Specifically, the servo motor 34 transmits power and torque to the driving wheel among the planetary gears 32 through the driving gear 33, and the planetary gears 32 transmit the power to the sun gear 310 again, causing the sun gear 310 to rotate; further, the sun gear assembly 31 is connected to the discharge barrel 20 through a flange 313. As the sun gear 310 rotates, the discharge barrel 20 makes a pendulum motion accordingly, realizing the discharge of the rubber material into the receiving barrels at different workstations. Preferably, the sun gear 310, the planetary gears 32, and the driving gear 33 are all made of high-strength steel, having a large load-bearing strength and driving power. Further, the sun gear assembly 31 is a hollow structure, and the sun gear assembly 31 and the transition barrel 10 are in clearance fit to enable the sun gear assembly 31 to rotate relative to the sun gear assembly 31; preferably, the clearance is 0.1 mm. At least two sealing ring grooves 311 are provided at the circumferential position where the inner circumference of the sun gear assembly 31 and the outer circumference of the transition barrel 10 are in clearance fit. A sealing member 312 is arranged in the sealing ring grooves 311. Preferably, the sealing member 312 is an O-ring. Such a design can not only ensure the clearance fit between the sun gear assembly 31 and the transition barrel 10, but also play a sealing role.

[0042] Regarding the positioning mechanism: The positioning mechanism acts on the sun gear assembly 31 to restrict the coaxial rotation of the sun gear assembly 31 relative to the transition barrel 10. The sun gear 310 is fixedly connected to the discharge barrel 20 through a flange 313. A fixing ring 41 parallel to the fixing plate 11 is fixedly sleeved on the outer circumference of the flange 313. Between the fixing plate 11 and the fixing ring 41 and equally spaced along the circumferential direction of the sun gear 310, there are the same number of fixing shafts 42 as the planetary gears 32. The planetary gears 32 are sleeved on the fixing shafts 42. The fixing shafts 42, the fixing ring 41 and the transition barrel 10 form an integral body through fixing bolts. The positioning mechanism includes a bearing wheel 43 and a bolt bearing 44; wherein, the bearing wheel 43 is coaxially arranged with the fixing shaft 42, and one side surface of the bearing wheel 43 is in contact with the tooth side surface of the sun gear 310 to ensure that the sun gear 310 rotates within a certain range here; the bolt bearings 44 are evenly distributed on a side surface of the fixing ring 41 facing away from the sun gear and are tangent to the outer circumference of the flange 313 to ensure that the rotation of the sun gear 310 at the flange 313 is within a certain range. Through the bearing positioning methods installed at the above two places, it is ensured that the sun gear 310 and the transition barrel 10 rotate coaxially, ensuring the rotation accuracy. Preferably, three groups of the bearing wheels 43 and the bolt bearings 44 are evenly distributed along the outer circumferential direction of the sun gear assembly 31.
