Description

Technical Field

[0001] This utility model relates to the field of spinning equipment technology, specifically to a special screw device for spinning with a large aspect ratio. Background Technology

[0002] In the spinning process, high aspect ratio screw equipment can better realize the functions of material conveying, melting, mixing and metering, thereby improving the quality and efficiency of spinning. However, existing high aspect ratio spinning screw equipment is usually a one-piece structure with a long overall length. This makes it extremely difficult to operate when the equipment malfunctions and needs to be repaired or the inside of the screw needs to be cleaned. Due to the excessive length of the screw, it is difficult for maintenance personnel to go deep into the inside of the screw for inspection and cleaning. Moreover, the length problem can easily cause the screw to deform during disassembly and installation, affecting the service life and performance of the equipment. Utility Model Content

[0003] In view of the problems existing in the current large aspect ratio spinning screw equipment, this utility model is proposed.

[0004] Therefore, the purpose of this utility model is to provide a special screw device for spinning with a large aspect ratio, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A high aspect ratio spinning screw device includes a base plate and vertical plates. Vertical plates are fixedly mounted on both sides of the upper surface of the base plate. A first tube is fixedly mounted on the upper side of one vertical plate, and a second tube is fixedly mounted on the upper side of the other vertical plate. A third tube is positioned between the first and second tubes. A conveying screw is rotatably mounted inside each of the first, second, and third tubes. A first motor is fixedly mounted on the outer side of the first tube, and its output end is fixedly connected to one end of the corresponding conveying screw. An extrusion head is fixedly mounted on one end of the outer side of the second tube. A support plate is fixedly mounted in the middle of the upper surface of the base plate. A limit block is fixedly mounted on the upper surface of the support plate. A through hole is opened in one end of the limit block, and a connecting rod is movably fitted inside the through hole. The lower end of the connecting rod is fixedly connected to the third tube. A drive mechanism for moving the connecting rod is provided on the front side of the support plate. Transmission mechanisms for synchronously rotating multiple conveying screws are provided at both ends of the third tube.

[0007] Preferably, the driving mechanism includes a turntable and a movable ring. A transmission rod is rotatably mounted on the front side of the support plate. The turntable is fixedly sleeved on the wall of the transmission rod. A round pin is eccentrically mounted on the front side of the turntable. The movable ring is fixedly mounted on the lower end of the connecting rod. The front end of the round pin passes through the movable ring. A motor is fixedly mounted on the rear side of the support plate. The output end of the motor is fixedly connected to one end of the transmission rod.

[0008] Preferably, the transmission mechanism includes a first bevel gear and a second bevel gear. Vertical rods are rotatably sleeved on the lower sides of the first tube and the second tube near the third tube and both ends of the third tube. Spur gears are fixedly sleeved on the lower ends of the multiple vertical rods. Two adjacent spur gears on both sides are meshed together. Multiple first bevel gears are fixedly sleeved on the lower ends of the two conveying screws on both sides and both ends of the middle conveying screw. Multiple second bevel gears are fixedly sleeved on the upper ends of the corresponding vertical rods. Multiple first bevel gears are meshed with the corresponding second bevel gears.

[0009] Preferably, sealing rings are fixedly provided at one end of the first tube and the second tube near the third tube and at both ends of the third tube, with the two sealing rings on both sides abutting each other.

[0010] Preferably, a retaining ring is fixedly sleeved at the end of the round pin away from the turntable.

[0011] Preferably, the cross-sections of the connecting rod and the through hole are both rectangular.

[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0013] 1. In this utility model, a second motor drives a conveying screw on one side to rotate. Through the transmission of multiple sets of first bevel gears, second bevel gears and spur gears, multiple conveying screws rotate synchronously, thus enabling stable spinning and extrusion operations.

[0014] 2. In this utility model, the first motor drives the turntable to rotate, causing the round pin to rotate around the transmission rod as the axis. During this process, the round pin slides inside the movable ring, which can push the movable ring to move longitudinally. This causes the connecting rod to drive the third tube to move longitudinally, so that the third tube separates from the first and second tubes, thus dividing the equipment into three sections. Each section is relatively short, making it convenient for maintenance and cleaning. Attached Figure Description

Vertical plates 2 are fixedly installed on both sides of the upper surface of the base plate 1. A first tube 3 is fixedly installed on the upper side of one vertical plate 2, and a second tube 4 is fixedly installed on the upper side of the other vertical plate 2. A third tube 5 is installed between the first tube 3 and the second tube 4. A conveying screw 21 is rotatably installed inside the first tube 3, the second tube 4 and the third tube 5. A first motor 7 is fixedly installed on the outer side of the first tube 3. The output end of the first motor 7 is fixedly connected to one end of the corresponding conveying screw 21. An extrusion head 6 is fixedly installed on one end of the outer side of the second tube 4. A support plate 10 is fixedly installed in the middle of the upper surface of the base plate 1. A limit block 15 is fixedly installed on the upper surface of the support plate 10. A through hole is opened in one end of the limit block 15. A connecting rod 8 is movably sleeved inside the through hole. The lower end of the connecting rod 8 is fixedly connected to the third tube 5. The cross-section of the connecting rod 8 and the through hole are both rectangular, so that the connecting rod 8 cannot rotate, that is, it can slide stably.

[0025] Example 2

[0026] Reference Figure 1-3 The front side of the support plate 10 is provided with a drive mechanism that drives the connecting rod 8 to move. The drive mechanism includes a turntable 12 and a movable ring 13. A transmission rod 11 is rotatably provided on the front side of the support plate 10. The turntable 12 is fixedly sleeved on the rod wall of the transmission rod 11. A round pin 14 is eccentrically provided on the front side of the turntable 12. The movable ring 13 is fixedly provided on the lower end of the connecting rod 8. The front end of the round pin 14 passes through the movable ring 13. A motor 16 is fixedly provided on the rear side of the support plate 10. The output end of the motor 16 is fixedly connected to one end of the transmission rod 11. A retaining ring is fixedly sleeved on the end of the round pin 14 away from the turntable 12 to prevent the round pin 14 from slipping out of the movable ring 13 as much as possible.

[0027] Example 3

[0028] Reference Figure 1-3 The third tube 5 is provided with a transmission mechanism at both ends to make multiple conveying screws 21 rotate synchronously. The transmission mechanism includes a first bevel gear 17 and a second bevel gear 18. The first tube 3 and the second tube 4 are rotatably sleeved with vertical rods 19 at the ends of the first tube 3 and the second tube 4 near the third tube 5 and at the lower sides of both ends of the third tube 5. The lower ends of multiple vertical rods 19 are fixedly sleeved with spur gears 20. Two adjacent spur gears 20 on both sides are meshed and connected.

Multiple first bevel gears 17 are meshed and connected with the corresponding second bevel gears 18.

[0029] Example 4

[0030] Reference Figure 1-3 Sealing rings 9 are fixedly provided at one end of the first tube 3 and the second tube 4 near the third tube 5 and at both ends of the third tube 5. The two sealing rings 9 on both sides are abutted against each other to improve the sealing between the two ends of the third tube 5 and the corresponding first tube 3 and second tube 4.

[0031] In this invention, during use, the second motor 16 drives the conveying screw 21 on one side to rotate. Through the transmission of multiple sets of first bevel gears 17, second bevel gears 18 and spur gears 20, multiple conveying screws 21 rotate synchronously, thus enabling stable spinning and extrusion. The first motor 7 drives the turntable 12 to rotate, causing the round pin 14 to rotate around the transmission rod 11. During this time, the round pin 14 slides within the movable ring 13, which can push the movable ring 13 to move longitudinally. This causes the connecting rod 8 to drive the third tube 5 to move longitudinally, separating the third tube 5 from the first tube 3 and the second tube 4, thus dividing the equipment into three sections. Each section is relatively short, making maintenance and cleaning convenient.

[0032] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
