Description

Technical Field

[0001] This invention relates to the field of mechanical equipment technology, and specifically to a belt tensioning mechanism. Background Technology

[0002] Existing strapping machines use gear transmission for their strapping tensioning mechanism. When using the machine, operators must manually insert the strapping into the inlet to start it. However, because the gear parts around the inlet are exposed, and the gears have the physical characteristics of rotation and meshing, there is a safety hazard of operators' fingers being crushed by the gears during use, installation, and adjustment of the strapping machine.

[0003] Therefore, this application studies a feeding and unloading belt tensioning mechanism, which reduces the risk of fingers being crushed and improves safety. Utility Model Content

[0004] To reduce the risk of fingers being crushed and improve safety, this application provides a feed and unload belt tensioning mechanism.

[0005] This application provides a belt tensioning mechanism for feeding and unloading, which adopts the following technical solution:

[0006] A belt tensioning mechanism includes a mounting frame, a transmission assembly, and a partition. The transmission assembly includes a gear. The mounting frame is provided with a rotating groove and a rotating shaft. The gear is rotatably connected to the rotating shaft and located in the rotating groove. The partition has a clearance groove and is mounted on the mounting frame. The transmission assembly passes through the clearance groove, and the partition covers the teeth of the gear.

[0007] By adopting the above technical solution, the partition covers the meshing part of the gear, effectively preventing operators from touching the dangerous area of ​​the gear with their fingers during use, installation and debugging, significantly reducing the risk of fingers being crushed and improving the overall safety of the baling machine.

[0008] Optionally, the partition includes a first partition and a second partition, which are respectively connected to the mounting brackets on both sides of the gear and are assembled to form a rotating groove.

[0009] By adopting the above technical solution, it becomes easier to install the partition and gears.

[0010] Optionally, the gear includes a driving gear and a driven gear that mesh with each other, and the rotating shaft is arranged in a one-to-one correspondence with the gear. The driving gear is coaxially connected to a first tensioning wheel, and the driven gear is coaxially connected to a second tensioning wheel. The first tensioning wheel and the second tensioning wheel are located on the side of the partition away from the gear, and a gap is left between the first tensioning wheel and the second tensioning wheel.

[0011] By adopting the above technical solution, the feed belt is pulled in between the first tension wheel and the second tension wheel. The rotation of the driving wheel drives the driven wheel to rotate, thereby driving the first tension wheel and the second tension wheel to move the feed belt.

[0012] Optionally, a guide member is provided at a distance on one side of the first tensioning wheel, and a guide channel is formed between the guide member and the first tensioning wheel. The guide channel is connected to the distance between the first tensioning wheel and the second tensioning wheel.

[0013] By adopting the above technical solution, the packing strap is inserted between the first tensioning wheel and the second tensioning wheel, and the packing strap is fed and unloaded along the guide rail by the transmission of the first tensioning wheel and the second tensioning wheel.

[0014] Optionally, the second tensioning wheel is provided with two inserts on the side away from the guide member, and an insertion channel is formed between the two inserts. The insertion channel is connected to the distance between the first tensioning wheel and the second tensioning wheel.

[0015] By adopting the above technical solution, the strapping is first manually inserted from the insertion channel between the first tensioning wheel and the second tensioning wheel, which moves the strapping. This further isolates the operator from the first tensioning wheel and the second tensioning wheel, and also avoids potential safety hazards to the operator during the rotation of the first tensioning wheel and the second tensioning wheel, thus further improving safety.

[0016] Optionally, a cover plate is also included, wherein the insertion channel and the guide channel are connected by the gap between the first tensioning wheel and the second tensioning wheel to form a belt channel, and the cover plate is detachably installed on the belt channel and at least partially covers the first tensioning wheel and the second tensioning wheel.

[0017] By adopting the above technical solution, when abnormal situations such as bending, jamming, or breakage of the strapping occur, only the cover plate needs to be removed, which facilitates maintenance. Furthermore, closing the cover plate during operation can better prevent workers from putting their hands between the first and second tensioning rollers, thus ensuring greater safety.

[0018] Optionally, the guide has a fixing hole, a fixing member is provided in the fixing hole, and the cover plate has a connecting hole, which is fixed to the guide by the fixing member.

[0019] Optionally, the fastener has a "T" shaped structure, is installed in the fixing hole and has a gap between its end and the guide member, the connecting hole includes a first connecting section and a second connecting section, the diameter of the first connecting section is larger than the diameter of the second connecting section; during installation, the first connecting section is inserted into the fastener and moves, the second connecting section is engaged with the fastener, and the end of the fastener abuts against the outside of the cover plate.

[0020] By adopting the above technical solution, the cover plate can be easily installed through a snap-fit ​​method, and the cover plate can be stably fixed.

[0021] In summary, this application includes the following beneficial technical effects:

[0022] 1. The partition covers the meshing part of the gear, effectively preventing operators from touching the dangerous area of ​​the gear with their fingers during use, installation and debugging, significantly reducing the risk of fingers being crushed and improving the overall safety of the baler;

[0023] 2. First, manually insert the strapping into the passageway between the first tensioning wheel and the second tensioning wheel to move the strapping. This further isolates the operator from the first and second tensioning wheels and avoids potential safety hazards to the operator during the rotation of the first and second tensioning wheels, thus further improving safety.

[0024] 3. The cover plate allows for easy maintenance in case of abnormalities such as bending, jamming, or breakage of the strapping. Furthermore, keeping the cover plate on during operation better prevents workers from putting their hands between the first and second tensioning rollers, thus ensuring greater safety.

[0034] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0035] This application discloses a tensioning mechanism for a feed / retractable belt. (Refer to...) Figure 1 and Figure 2 The conveyor belt tensioning mechanism includes a mounting frame 1, a transmission assembly 2, and a partition 3. The transmission assembly 2 includes a gear 21. The mounting frame 1 is provided with a rotating groove 4 and a rotating shaft 5. The rotating shaft 5 is driven by a motor to rotate the gear 21. The gear 21 is rotatably connected to the rotating shaft 5 and located in the rotating groove 4. The partition 3 has a clearance groove and is installed on the mounting frame 1. The transmission assembly 2 passes through the clearance groove, and the partition 3 covers the teeth of the gear 21, effectively preventing operators from contacting the dangerous area of ​​the gear 21 with their fingers during use, installation, and debugging. This significantly reduces the risk of fingers being crushed and improves the overall safety of the baler.

[0036] Reference Figure 1 and Figure 3In some embodiments, the partition 3 includes a first partition 31 and a second partition 32, which are respectively connected to the mounting brackets 1 on both sides of the gear 21 and are assembled to form a rotating groove 4. In this embodiment, the first partition 31 and the second partition 32 cover the meshing teeth of the gear 21 by assembling on both sides, which facilitates the installation of the partition 3. Both the first partition 31 and the second partition 32 are provided with multiple locking holes 12. The cross-section of the locking holes 12 is T-shaped. Bolts pass through the locking holes 12 and are screwed to the mounting brackets 1, and the nuts of the bolts can be located inside the T-shaped end of the locking holes 13.

[0037] Reference Figure 1 and Figure 4 In some embodiments, gear 21 includes a driving gear 211 and a driven gear 212 that mesh with each other. The rotating shaft 5 is arranged in a one-to-one correspondence with gear 21. In this embodiment, the motor drives the rotating shaft 5 to rotate the driving gear 211. The motor is installed on the side of the mounting frame 1 away from the gear 21, and the rotating shaft 5 passes through and limits the rotation on the mounting frame 1. The driving gear 211 meshes with the driven gear 212 to drive the driven gear 212 to rotate. The rotating shaft 5 of the driven gear 212 is used to limit the rotation of the driven gear 212 to the mounting frame 1.

[0038] The drive wheel 211 is coaxially connected to the first tension wheel 22, and the driven wheel 212 is coaxially connected to the second tension wheel 23. In this embodiment, the drive wheel 211 and the first tension wheel 22 are integrally formed, and a gap is left between them near the periphery for the partition 3 to accommodate them. The driven wheel 212 and the second tension wheel 23 are also integrally formed, and a gap is left between them near the periphery for the partition 3 to accommodate them. The first tension wheel 22 and the second tension wheel 23 are located on the side of the partition 3 away from the gear 21 and partially cover the partition 3. A gap is left between the first tension wheel 22 and the second tension wheel 23 for conveying the packing strap.

[0039] Reference Figure 5 In some embodiments, a guide member 6 is provided at intervals on one side of the first tensioning wheel 22, and a guide channel 7 is formed between the guide member 6 and the first tensioning wheel 22. The guide channel 7 is connected to the distance between the first tensioning wheel 22 and the second tensioning wheel 23, and the curvature of the guide channel 7 is consistent with the curvature of the drive wheel 211 near the guide member 6, so that the packing strap can be smoothly conveyed.

[0040] In some embodiments, the second tensioning wheel 23 has two inserts 8 on the side opposite to the guide member 6, forming an insertion channel 9 between the two inserts 8. The insertion channel 9 is connected to the distance between the first tensioning wheel 22 and the second tensioning wheel 23, and the curvature of the insertion channel 9 can smoothly connect with the curvature of the second tensioning wheel 23. The inserts 8 can better prevent the workers from coming into contact with the entry side of the first tensioning wheel 22 and the second tensioning wheel 23, thus better ensuring operational safety.

[0041] In this embodiment, the guide member 6 has multiple locking holes 13. The cross-section of the locking hole 13 is T-shaped. The bolt passes through the locking hole 13 and is screwed to the partition 3. The nut of the bolt can be located inside the T-shaped end of the locking hole 13.

[0042] Reference Figure 6 In some embodiments, a cover plate 10 is also included. The insertion channel 9 and the guide channel 7 are connected by the gap between the first tensioning wheel 22 and the second tensioning wheel 23 to form a belt channel. The cover plate 10 is detachably installed on the belt channel and at least partially covers the first tensioning wheel 22 and the second tensioning wheel 23. In this embodiment, the cover plate 10 also completely covers the guide member 6 and the insertion member 8. The detachable design of the cover plate 10 facilitates maintenance when the packing strap malfunctions. Furthermore, the cover plate 10 can cover the belt channel between the first tensioning wheel 22 and the second tensioning wheel 23, further preventing safety hazards caused by workers accidentally inserting their hands.

[0043] Reference Figure 5 and Figure 6 In some embodiments, the guide member 6 is provided with a fixing hole 11, and a fixing member (not shown in the figure) is provided in the fixing hole 11. The cover plate 10 is provided with a connecting hole 14, and the connecting hole 14 is fixed to the guide member 6 by the fixing member.

[0044] In some embodiments, the fastener is a "T"-shaped structure, which can be any "T"-shaped structure such as a bolt, screw, or "T"-shaped fixing rod. The fastener is installed in the fixing hole 11 with a gap between its end and the guide member 6, that is, a gap is left between the end of the "T"-shaped structure and the guide member 6. In this embodiment, this gap is equal to the thickness of the cover plate 10. The connecting hole 14 includes a first connecting section and a second connecting section. The diameter of the first connecting section is larger than the diameter of the second connecting section, that is, the connecting hole 14 has a gourd-shaped structure, and the first connecting section is located to the left of the second connecting section. During installation, the first connecting section is inserted into the fastener and moved to the left, and the second connecting section is engaged with the fastener, with the "T"-shaped end of the fastener abutting against the outside of the cover plate 10. This allows the cover plate 10 to be easily fixed, and when disassembling, it is only necessary to move the cover plate 10 to the right and then pull it forward.

[0045] In this embodiment, the guide member 6 has multiple fixing holes 11, the insert member 8 also has fixing holes 11, and the connecting hole 14 of the cover plate 10 is correspondingly provided with the fixing holes 11.

[0046] In other embodiments, the fastener can also be a bolt, the fixing hole 11 can be a threaded hole, and the connecting hole 14 can be a round hole. The cover plate 10 is fixed to the guide member 6 by bolting the bolt to the threaded hole.

[0047] The implementation principle of the feeding and unloading tensioning mechanism in this application embodiment is as follows: the partition 3 covers the meshing part of the gear 21, which effectively avoids the operator's fingers from coming into contact with the dangerous area of ​​the gear 21 during use, installation and debugging, significantly reduces the risk of fingers being crushed, and improves the overall safety of the packing machine.
