Description

Technical Field

[0001] This utility model relates to the field of electrothermal sleeve processing technology, and more specifically, it relates to an extruder feeding device for electrothermal sleeve processing. Background Technology

[0002] In traditional electrothermal sleeve processing, the feeding device's conveying system typically relies on a simple spiral plate and rotating rod structure for material transport. However, this structure may encounter problems such as material blockage or excessive material feeding when faced with different types of raw materials. This unstable conveying method not only increases the failure rate in production but also requires operators to invest more time and effort in dealing with blockages and material overload. Furthermore, due to the lack of precise pressure regulation and feedback mechanisms, existing technology cannot automatically adjust mechanical parameters when faced with different material characteristics, thereby affecting the stability and efficiency of the production process.

[0007] The present invention is further configured such that each of the multiple sets of compression springs is fixedly provided with a push block at its bottom end, and the multiple sets of push blocks slide in the multiple sets of sliding holes respectively, which enhances the stability of the compression springs and the flexibility of the push blocks, and improves the adjustment accuracy of the device.

[0008] The present invention is further configured such that the outer wall of the connecting sleeve is provided with a sliding groove, and multiple sets of the sliding groove are slidably connected to the transmission sleeve.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides an extruder feeding device for electrothermal sleeve processing, which has the following advantages:

[0016] 1. This device uses a motor to drive the connecting rod to engage with the locking block, which in turn drives the rotating rod to rotate and drive the spiral plate to convey materials, effectively achieving stable material conveying. This design can automatically adjust when the material resistance is too high, avoiding overload. When the locking block encounters excessive resistance, it will disengage from the slot and self-adjust by pressing the spring with the push block, avoiding damage to the motor and other components, thereby improving the reliability and service life of the system.

[0017] 2. The precise adjustment mechanism of this device also significantly improves the conveying efficiency. By rotating the sleeve to drive the meshing of the gear ring and the gear, the threaded fit between the screw and the transmission sleeve is adjusted, and the preset force of the compression spring is precisely adjusted. This adjustment process can optimize the performance of the device according to the needs of different working conditions, making the material conveying more stable and efficient.

[0018] 3. If material gets stuck during the conveying process, the cooperation of the jamming block and the pusher block can effectively release the obstruction when the system encounters a blockage, and quickly restore the normal working state after the motor stops, ensuring the long-term stable operation of the equipment.

[0028] Please see Figures 1-5A feeding device for an extruder used in electrothermal welding sleeve processing includes a support frame 1, a conveying cylinder 2 fixedly mounted on the support frame 1, a rotating rod 3 rotatably mounted inside the conveying cylinder 2, a spiral plate 4 fixedly mounted on the outer side of the rotating rod 3, a motor 5 fixedly mounted on the top surface of the support frame 1, a connecting rod 6 fixedly mounted on the output end of the motor 5, a connecting sleeve 7 fixedly mounted on one end of the rotating rod 3, the connecting rod 6 being inserted into the connecting sleeve 7, a locking block 8 slidably mounted on the inner side of the connecting sleeve 7, a locking groove 9 being provided on the outer wall of the connecting rod 6, multiple sets of locking grooves 9 being provided and engaging with multiple sets of locking blocks 8 respectively, a sliding hole 10 being provided on the outer wall of the connecting sleeve 7, multiple sets of sliding holes 10 being provided and each set of sliding holes 10 having a sliding abutment block 11 slidably mounted on its inner side, the multiple sets of abutment blocks 11 abutting against the outer wall of the multiple sets of locking blocks 8 respectively, and a compression spring 12 being connected to the bottom surface of each set of abutment blocks 11.

[0029] Each of the multiple sets of compression springs 12 has a push block 13 fixedly installed at its bottom end, and the multiple sets of push blocks 13 slide in the multiple sets of sliding holes 10 respectively.

[0030] The outer wall of the connecting sleeve 7 is provided with a sliding groove 14. Multiple sets of sliding grooves 14 are provided and are slidably connected to a transmission sleeve 15. Multiple sets of push blocks 13 are fixedly connected to the transmission sleeve 15.

[0031] The outer wall of the connecting sleeve 7 is rotatably provided with a rotating sleeve 16, the inner side of the rotating sleeve 16 is fixedly provided with a toothed ring 17, and the outer side of the connecting sleeve 7 is rotatably provided with a screw 18. Multiple sets of screws 18 are provided and are all threadedly connected to the transmission sleeve 15. The top of each set of screws 18 is fixedly provided with a gear 19, and the multiple sets of gears 19 mesh with the toothed ring 17.

[0032] The bottom of the multiple card blocks 8 and the multiple card slots 9 are both designed to be arc-shaped.

[0033] Multiple sets of abutment blocks 11 and push blocks 13 are fixedly provided with guide blocks 20 on their outer walls. Guide grooves 21 are provided on the inner wall of sliding holes 10. Multiple sets of guide grooves 21 and guide blocks 20 are provided and are slidably connected.

[0034] The inner sides of the multiple sets of abutting blocks 11 are all set in an arc shape and abut against the outer sides of the multiple sets of locking blocks 8 respectively.

[0035] A feed hopper 22 is fixedly provided on the top surface of the conveying cylinder 2, and a discharge pipe 23 is fixedly provided on the bottom surface of the conveying cylinder 2.

[0036] In this embodiment, during use, the raw material is injected into the feed hopper 22. The motor 5 drives the connecting sleeve 7 to rotate by engaging with the locking blocks 8 through multiple sets of slots 9 on the outer wall of the connecting rod 6. The connecting sleeve 7 drives the rotating rod 3 to rotate, and the rotating rod 3 drives the spiral plate 4 to transport the raw material. Then, the material is fed through the discharge pipe 23. When the material in the conveying cylinder 2 is stuck in the spiral plate 4, it generates a certain resistance to the rotating rod 3. When the resistance is greater than the preset force of the multiple sets of pressure springs 12, the multiple sets of locking blocks 8 disengage from the slots 9 and push the multiple sets of push blocks 13 to squeeze the pressure springs 12, so that the connecting rod 6 driven by the motor 5 rotates freely in the connecting sleeve 7. After the motor 5 is turned off, the multiple sets of pressure springs 12 push the push blocks 13, and the push blocks 13 push the multiple sets of locking blocks 8 to reset and engage in the slots 9, restoring the connection between the connecting sleeve 7 and the connecting rod 6.

[0037] More specifically, the rotating sleeve 16 drives the gear ring 17 to mesh with multiple sets of gears 19, which in turn drives the screw 18 to rotate and engage with the transmission sleeve 15. This causes the transmission sleeve 15 to drive multiple sets of push blocks 13 to squeeze multiple sets of pressure springs 12, thereby increasing the preset force of the multiple sets of pressure springs 12 on the push blocks 13, and conversely, decreasing the preset force of the pressure springs 12.

[0038] In summary, during use or operation of the overall equipment: When in use, raw materials are injected into the feed hopper 22. The motor 5 drives the connecting sleeve 7 to rotate through multiple sets of slots 9 and locking blocks 8 on the outer wall of the connecting rod 6. The connecting sleeve 7 drives the rotating rod 3 to rotate, and the rotating rod 3 drives the spiral plate 4 to convey the raw materials. Then, the materials are fed through the discharge pipe 23. When the material in the conveying cylinder 2 is stuck in the spiral plate 4, it generates a certain resistance to the rotating rod 3. When the resistance is greater than the preset force of the multiple sets of pressure springs 12, the multiple sets of locking blocks 8 disengage from the slots 9 and push the multiple sets of push blocks 13 to squeeze the pressure springs 12, causing the connecting rod 6 driven by the motor 5 to rotate freely in the connecting sleeve 7. After the motor 5 is turned off, the multiple sets of pressure springs 12 push the push blocks 13, and the push blocks 13 push the multiple sets of locking blocks 8 to reset and engage in the slots 9, restoring the connection between the connecting sleeve 7 and the connecting rod 6.

[0039] The rotating sleeve 16 drives the gear ring 17 to mesh with multiple sets of gears 19, which in turn drives the screw 18 to rotate and engage with the transmission sleeve 15. This causes the transmission sleeve 15 to drive multiple sets of push blocks 13 to squeeze multiple sets of pressure springs 12, thereby increasing the preset force of the multiple sets of pressure springs 12 on the push blocks 13, and conversely, decreasing the preset force of the pressure springs 12.

Since the devices matched with the controllers are common devices, their control principles and wiring connections are existing, well-known, and mature technologies, and their specific circuit structures will not be described in detail here.
