Description

Technical Field

[0001] This application relates to the field of baling machines, and more particularly to a special tool for baling machine maintenance. Background Technology

[0002] The baling machine plays a crucial role; it is a key piece of equipment that ensures that PTA feed bags can be effectively compressed and packaged.

[0003] During the maintenance of a baling machine, if the hydraulic piston of the baling machine falls off, it usually makes the sealing device difficult to disassemble.

[0004] In response to the aforementioned technologies, the inventors designed a tool that facilitates easy disassembly of the sealing device from the hydraulic piston of the packing machine. Utility Model Content

[0005] To facilitate easy disassembly of the sealing device from the hydraulic piston of the baling machine, this application provides a special tool for baling machine maintenance.

[0006] The technical solution for a special tool for repairing a baling machine provided in this application is as follows:

[0007] A special tool for repairing a packing machine includes an insert, a main body, and a striking part. The insert has at least one first wedge-shaped surface. The insert is used to be inserted between the hydraulic piston and the sealing device of the packing machine. The insert is connected to the main body. The striking part is slidably connected to the main body in a direction close to or away from the insert and is capable of contacting the insert.

[0008] By adopting the above technical solution, when in use, the first wedge-shaped surface of the embedding part is embedded between the hydraulic piston and the sealing device. Then, the striking part is struck, so that the embedding part is struck by the striking part, which makes it easier for the operator to apply force to the embedding part and reduces the occurrence of short life of the main body due to direct striking of the main body. Then, the hydraulic piston and the sealing device are pried by the main body to achieve convenient disassembly.

[0009] Preferably, the main body includes a first rod and a second rod, the first rod and the second rod are arranged perpendicularly to each other and connected to each other, the embedded part is connected to the first rod, the first rod and the embedded part are both located on the same side of the second rod, the striking part is located between the embedded part and the second rod, and the striking part is slidably sleeved on the first rod.

[0010] With the first and second rods in place, if the embedded part is misaligned, the operator can tap the striking part to make it interact with the second rod, thereby knocking the first rod and the embedded part out from between the hydraulic piston and the sealing device of the packaging machine, and readjusting them for easier operation.

[0011] Preferably, the embedded part is slidably sleeved on the main body part, and the special tool for repairing the packaging machine includes a positioning pin. The main body part has a positioning hole, and one end of the positioning pin passes through the embedded part and is located in the positioning hole.

[0012] With the locating pin and locating hole, the insert can be disassembled by sliding the locating pin out of the locating hole, which facilitates the disassembly and replacement of inserts of different sizes, and also facilitates the replacement of the striking part.

[0013] Preferably, the positioning hole includes a first sub-positioning hole and a second sub-positioning hole, and the first sub-positioning hole and the second sub-positioning hole are distributed along the sliding direction of the embedding part.

[0014] By adjusting the relative position of the insert and the main body through the first and second sub-positioning holes, maintenance of packing machines with different depths can be achieved.

[0015] Preferably, the locating pin has a threaded portion, which is connected to the wall thread corresponding to the locating hole.

[0016] The threaded design reduces the likelihood of the locating pin falling out of the locating hole during operator tapping.

[0017] Preferably, the special tool for repairing the packaging machine includes a locking nut, which is located between the embedded part and the striking part, and is threadedly connected to the main body.

[0018] By tightening the locking nut, the embedded part and the positioning pin are pressed together, increasing the positive pressure between them and thus increasing the static friction. This reduces the likelihood of the positioning pin falling out of the positioning hole during operator tapping.

[0019] Preferably, the insert has a groove that is recessed from the surface of the insert toward the striking part to the interior of the insert, and the locking nut is located within the groove.

[0020] The groove design reduces the direct impact between the striking part and the lock nut, thus minimizing damage to the lock nut.

[0021] Preferably, the special tool for repairing the packaging machine includes a guide pin and a return spring. The main body has a sliding groove. The guide pin is at least partially slidably connected in the sliding groove. The return spring is located between the guide pin and the bottom of the sliding groove. One end of the return spring is connected to the bottom of the sliding groove, and the other end of the return spring is connected to the guide pin.

[0022] With the guide needle and return spring, during use, the tip of the guide needle can be inserted between the hydraulic piston and the sealing device first. Then, under the guidance of the guide needle, the insertion part can be more accurately impacted and inserted between the hydraulic piston and the sealing device. Attached Figure Description

[0029] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0030] This application discloses a special tool for repairing a packing machine. (Refer to...) Figure 1 as well as Figure 2 The special tool for repairing a packing machine includes a main body 2, an embedded part 1, and a striking part 3. The main body 2 includes a first rod 21 and a second rod 22. The first rod 21 and the second rod 22 are fixedly connected, and one end of the first rod 21 is fixedly connected to the middle part of the second rod 22.

[0031] Reference Figure 1 as well as Figure 2 The end of the first rod 21 away from the second rod 22 has at least one second wedge-shaped surface 212, specifically, it has two second wedge-shaped surfaces 212, and the two second wedge-shaped surfaces 212 form a straight line.

[0032] Reference Figure 1as well as Figure 2 The embedding part 1 has at least one first wedge surface 11, specifically, it has two first wedge surfaces 11, and the two first wedge surfaces 11 form a straight line between them. The embedding part 1 is used to embed between the hydraulic piston of the packaging machine and the sealing device.

[0033] Reference Figure 1 as well as Figure 2 Both first wedge surfaces 11 are located on the side of the embedded part 1 away from the second rod 22; the two first wedge surfaces 11 correspond one-to-one with the two second wedge surfaces 212, and the first wedge surfaces 11 and the second wedge surfaces 212 are arranged in parallel.

[0034] Reference Figure 1 as well as Figure 2 The insert 1 is slidably sleeved on the first rod 21. The first rod 21 and the insert 1 are both located on the same side of the second rod 22. In another embodiment, the insert 1 can also be fixedly connected to or welded to the first rod 21. The special tool for repairing the packing machine includes a positioning pin 4. The first rod 21 has a positioning hole 211. One end of the positioning pin 4 passes through the insert 1 and is located in the positioning hole 211.

[0035] Reference Figure 1 as well as Figure 2 The positioning hole 211 includes a first sub-positioning hole 2111 and a second sub-positioning hole 2112. The positioning pin 4 is located in the first sub-positioning hole 2111. The first sub-positioning hole 2111 and the second sub-positioning hole 2112 are distributed along the sliding direction of the embedded part 1. The second sub-positioning hole 2112 is located on the side of the first sub-positioning hole 2111 away from the second rod 22. In other words, the second sub-positioning hole 2112 is located between the first sub-positioning hole 2111 and the second wedge surface 212.

[0036] Reference Figure 1 as well as Figure 2 The locating pin 4 has a threaded portion, which is connected to the wall thread corresponding to the first sub-locating hole 2111 or the second sub-locating hole 2112. Specifically, the locating pin 4 is a locating bolt.

[0037] Reference Figure 1 as well as Figure 2 The striking part 3 is slidably sleeved on the first rod 21. The striking part 3 is slidably connected to the first rod 21 in the direction of approaching or moving away from the embedded part 1. The striking part 3 is cylindrical and can contact the embedded part 1.

[0038] The implementation principle of a special tool for repairing a packing machine according to an embodiment of this application is as follows: Before use, the relative position between the embedded part 1 and the first rod 21 can be adjusted by adjusting the position of the positioning pin 4 in the first sub-positioning hole 2111 or the second sub-positioning hole 2112, thereby adapting to packing machines of different depths.

[0039] In use, the first wedge-shaped surface 11 is embedded between the hydraulic piston and the sealing device. Then, the operator taps the tapping part 3 to make the tapping part 3 tap the embedded part 1, thereby knocking the embedded part 1 into the space between the hydraulic piston and the sealing device. If it is necessary to knock the embedded part 1 out from between the hydraulic piston and the sealing device or adjust the angle, the tapping part 3 can be tapped to make the tapping part 3 collide with the first rod 21, thereby knocking both the main body 2 and the embedded part 1 out from between the hydraulic piston and the sealing device.

[0040] This application discloses another special tool for repairing a packing machine, which differs from the above embodiment in that the positioning pin 4 does not have a threaded portion. (Refer to...) Figure 3 as well as Figure 4 The special tool for repairing the baling machine includes a locking nut 5, which is located between the embedded part 1 and the striking part 3. The locking nut 5 is sleeved on the first rod 21 and is threadedly connected to the first rod 21.

[0041] Reference Figure 3 as well as Figure 4 The embedded part 1 includes a contact ring 13 with a groove 12. The contact ring 13 is located between the embedded part 1 and the striking part 3. The contact ring 13 and the embedded part 1 are integral parts. The end of the contact ring 13 facing away from the embedded part 1 can contact the striking part 3. The locking nut 5 is located in the groove 12 and is in contact with and abuts against the embedded part 1.

[0042] Reference Figure 3 as well as Figure 5 The special tool for repairing the packing machine includes a guide pin part 6 and a return spring 61. The end of the first rod 21 away from the second rod 22 is provided with a sliding groove 62. The extension direction of the sliding groove 62 is parallel to the extension direction of the first rod 21. The guide pin part 6 is at least partially slidably connected to the sliding groove 62. The return spring 61 is located in the sliding groove 62 and is located between the guide pin part 6 and the bottom of the sliding groove 62. One end of the return spring 61 is fixedly connected to the bottom of the sliding groove 62, and the other end of the return spring 61 is fixedly connected to the guide pin part 6.

[0043] The implementation principle of another special tool for repairing a baling machine in this application embodiment is as follows: Before use, the relative position between the embedded part 1 and the first rod 21 can be adjusted by changing the position of the positioning pin 4 in the first sub-positioning hole 2111 or the second sub-positioning hole 2112, thereby adapting to baling machines of different depths. By rotating the locking nut 5, the locking nut 5 can be pressed against the wedge-shaped part, making it more difficult for the positioning pin 4 to come out of the wedge-shaped part.

[0044] In use, the tip of the guide needle 6 is placed between the hydraulic piston and the sealing device. Then, guided by the guide needle 6, the first wedge-shaped surface 11 is slowly inserted between the hydraulic piston and the sealing device. The operator then taps the tapping part 3 to make the inserting part 1 tap into the space between the hydraulic piston and the sealing device. If it is necessary to knock the inserting part 1 out from between the hydraulic piston and the sealing device or adjust the angle, the tapping part 3 can be tapped to make it collide with the first rod 21, thereby knocking both the main body 2 and the inserting part 1 out from between the hydraulic piston and the sealing device.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
