[0022] The welding ring packaging equipment uses a welding ring bagging mechanism to package welding rings into heat shrink bags 10 to save manpower. Specifically, the welding ring packaging equipment has a bagging station and a welding ring bagging mechanism corresponding to the bagging station. A bagging rod 9 is set at the bagging station, and multiple welding rings are set on the bagging rod 9 along its axial direction. The multiple welding rings form a welding ring group on the bagging rod 9. The welding ring packaging equipment has an installation box, and the welding ring bagging mechanism is installed on the installation box. The welding ring bagging mechanism is used to put the welding ring group into the heat shrink bag 10, so as to facilitate the packaging of the entire welding ring group.

[0023] To achieve automatic bagging, this utility model embodiment provides a welding ring bagging mechanism, such as... Figure 1As shown, the assembly specifically includes a bag-rolling assembly 1, a bag-supporting rod 2, a traction assembly 3, and a cutting assembly 4. The bag-rolling assembly 1 is fixedly installed in the mounting box, and a heat-shrinkable bag 10 is wound around it. The radial inner dimension of the heat-shrinkable bag 10 after opening matches the radial outer dimension of the welding ring. This matching means that the inner diameter of the heat-shrinkable bag 10 when opened is clearance-fitted with the outer diameter of the welding ring. The bag-supporting rod 2 is axially arranged along the collar rod 9, and is parallel to the collar rod 9. The bag-supporting rod 2 is inserted through the opening of the heat-shrinkable bag 10 and opens the portion of the heat-shrinkable bag 10 that is packaged outside the welding ring assembly. The outer diameter of the bag-supporting rod 2 must also match the radial inner dimension of the heat-shrinkable bag 10 after opening, ensuring that the heat-shrinkable bag 10... The heat shrink bag 10 is fully opened, allowing its opening to be stably inserted into the welding ring assembly. The support rod 2 requires axial limiting, meaning it remains fixed axially relative to the mounting box, allowing the heat shrink bag 10 to move stably relative to it. The traction component 3, located radially outside the support rod 2, pulls the heat shrink bag 10 when it is fitted inside the heat shrink bag 10. This causes the heat shrink bag 10 to move axially relative to the support rod 2, bringing its opening closer to the welding ring assembly on the collar rod 9. Finally, the opening of the heat shrink bag 10 moves to the outside of the welding ring assembly and fits it onto the assembly. Internally, after the heat shrink bag 10 is fitted onto the outside of the welding ring assembly, and in order to ensure that the heat shrink bag 10 can be stably fitted onto the welding ring assembly and that the movement path along the welding ring assembly is shorter, when the traction component 3 moves, the collar rod 9 abuts against the support rod 2 along its axial direction, which also allows the heat shrink bag 10 to move stably relative to the support rod 2 along the axial direction of the collar rod 9. It should be noted that the outer wall of the support rod 2 can be made sufficiently smooth, so that even if the support rod 2 abuts against the heat shrink bag 10, the friction between the two is relatively small and will not affect the axial movement of the heat shrink bag 10 relative to the support rod 2. The cutting component 4 is located on the side of the support rod 2 axially close to the end of the collar rod 9. When the traction component 3 fits the heat shrink bag 10 onto the welding ring... After the outer side of the assembly is reached, the cutting component 4 operates to detach the heat shrink bag 10 of a preset length, which is fitted onto the outside of the welding ring assembly, from the heat shrink bag 10 on the roll assembly 1. The preset length is fixed and can be determined by controlling the distance the traction component 3 pulls the heat shrink bag 10, ensuring that the traction component 3 pulls the heat shrink bag 10 a constant distance each time. Through the cooperation of the roll assembly 1, the support rod 2, the traction component 3, and the cutting component 4, the heat shrink bag 10 can automatically open and fit onto the outside of the welding ring assembly. After the heat shrink bag 10 is fitted onto the outside of the welding ring assembly, it is cut and made independent. The welding ring assembly with the heat shrink bag 10 fitted can then proceed to the next process, realizing automated bagging of the welding ring assembly and saving manpower.

[0024] There are two scenarios for the cutting component 4 to cut the heat shrink bag 10. When the traction component 3 places the heat shrink bag 10 along the support rod 2 and relative to the support rod 2 on the outer periphery of the welding ring group, and then the traction component 3 stops pulling the heat shrink bag 10 and returns to its original position along the collar rod 9 away from the collar rod 9, the cutting component 4 will then cut the heat shrink bag 10. Alternatively, when the traction component 3 places the heat shrink bag 10 along the support rod 2 and relative to the support rod 2 on the outer periphery of the welding ring group, the cutting component 4 can cut the heat shrink bag 10. After cutting, the traction component 3 returns to its original position along the collar rod 9 away from the collar rod 9, waiting for the next traction of the heat shrink bag 10.

[0025] Specifically, in this embodiment, in order for the traction component 3 to drive the heat shrink bag 10 to move axially along the collar rod 9, the welding ring bagging mechanism also includes a drive component 5, such as... Figure 2 As shown, the drive assembly 5 specifically includes a driven part 51 and a power part 52. The power part 52 is fixedly installed on the mounting box, and the driven part 51 is connected to the output end of the power part 52. The power part 52 enables the driven part 51 to reciprocate along the collar rod 9 axial direction. The traction assembly 3 is fixedly installed on the driven part 51. The traction assembly 3 moves along the collar rod 9 axial direction with the driven part 51, thereby the traction assembly 3 clamps the heat shrink bag 10 and drives the heat shrink bag 10 to move along the collar rod 9 axial direction and be sleeved on the outside of the welding ring assembly. Specifically, the driven part 51 can be configured as a platform structure, and several clearance holes are provided on the platform structure to avoid other components during the movement of the driven part 51 along the collar rod 9 axial direction. Specifically, the power part 52 can be a linear transport mechanism, which can be a linear cylinder, a linear push rod motor, or a lead screw mechanism, etc. It is important to know that in order to ensure that the heat shrink bag 10, which is fitted onto the outside of the welding ring assembly, is always at the preset length after cutting, the traction component 3 must move the same distance along the axial direction of the collar rod 9 as the driven part 51.

[0026] Specifically, the traction assembly 3 includes a first clamping cylinder 31 and two abutting traction blocks 32. The two abutting traction blocks 32 approach each other under the drive of the first clamping cylinder 31 to abut the heat shrink bag 10 on the outside of the support rod 2. At this time, the heat shrink bag 10 also abuts the support rod 2. Under the drive of the drive assembly 5, the traction assembly 3 approaches the collar rod 9 along the axial direction. Under the drive of the friction between the abutting traction blocks 32 and the heat shrink bag 10, the bag opening of the heat shrink bag 10 moves toward the collar rod 9.

[0027] To further ensure consistent length of each heat shrink bag 10 cut, in this embodiment, the cutting assembly 4 is also fixedly mounted on the driven part 51. The cutting assembly 4 and the traction assembly 3 are spaced apart along the axial direction of the collar rod 9 on the driven part 51. Since the positions of the cutting assembly 4 and the traction assembly 3 on the driven part 51 are fixed, their distance along the axial direction of the collar rod 9 is also relatively fixed. Even if the cutting assembly 4 moves along the axial direction of the collar rod 9, the distance between them along the axial direction of the collar rod 9 will not change. The distance that the heat shrink bag 10 moves along the collar rod 9 under the traction of the traction component 3 is equal to the distance that the cutting component 4 moves along the collar rod 9. After the cutting component 4 and the traction component 3 are reset along with the driven part 51, the cutting component 4 then moves to cut the heat shrink bag 10 that is sleeved on the outside of the welding ring assembly, so that it is detached. Furthermore, the cutting component 4 is closer to the collar rod 9 along the collar rod 9 than the traction component 3, so that the cut of the heat shrink bag 10 after being cut by the cutting component 4 will be shorter.

[0028] In other embodiments, in order for the traction assembly 3 to drive the heat shrink bag 10 to move axially along the collar rod 9, such as Figures 4-5 As shown, the traction assembly 3 includes a rotatable rotating member 33. By having the rotating member 33 abut against the heat shrink bag 10, the heat shrink bag 10 can be supported by the bag support rod 2. When bagging is required, simply rotate the rotating member 33. The rotation of the rotating member 33 will cause it to abut against the heat shrink bag 10 through its outer wall, and the heat shrink bag 10 can move axially towards the collar rod 9 by relying on friction, thus achieving the movement purpose of the heat shrink bag 10. At this time, the traction assembly 3 and the cutting assembly 4 can be fixed to the mounting box or fixed to the mounting box by a fixing bracket. The traction assembly 3 and the cutting assembly 4 correspondingly pull the heat shrink bag 10 and cut... The heat shrink bag 10 can be cut; of course, the traction component 3 also includes a rotary motor, which drives the rotating part 33 to rotate as a power source. Preferably, the rotating part 33 can be a roller with a patterned surface to increase the friction between the rotating part 33 and the heat shrink bag 10, making the heat shrink bag 10 move more stably. The rotary motor can be a stepper motor, which can control the number of rotations of the rotating part 33, thereby controlling the axial movement distance of the heat shrink bag 10 along the collar rod 9, so that the length fitted on the outside of the welding ring group each time is the preset length, avoiding large changes in the axial length of the heat shrink bag 10 on the outside of the welding ring group. Specifically, the traction component 3 can be set as one or two sets, preferably two sets, such as Figure 5 As shown, the two sets of traction components 3 are symmetrically arranged about the axis of the support rod 2. The two rotating parts 33 in the two sets of traction components 3 clamp the heat shrink bag 10 and the support rod 2. The heat shrink bag 10 can move stably along the axial direction of the collar rod 9 under the action of the two rotating parts 33. The two sets of traction components 3 can also play a role in radially limiting the heat shrink bag 10 and the support rod 2, and can also increase the stability of the support rod 2 to a certain extent.

[0029] When the heat shrink bag 10 is fitted onto the outside of the welding ring assembly, the support rod 2 is limited by the axial contact of the collar rod 9 at the bag-fitting station. It's important to note that when the cutting assembly 4 cuts the heat shrink bag 10 fitted onto the outside of the welding ring assembly, the collar rod 9 needs to move axially away from the support rod 2, creating a gap between the collar rod 9 and the support rod 2. The cutting assembly 4 then cuts the heat shrink bag 10 located in the gap between the collar rod 9 and the support rod 2, making the heat shrink bag 10 fitted onto the outside of the welding ring assembly independent. However, when the cutting assembly 4 is active, the support rod 2 still needs to be axially limited. The welding ring bag-fitting mechanism is equipped with a support rod fixing part 6, which can be fixed to the mounting box. The support rod fixing part 6 is designed to both fix the support rod 2 and not affect the fitting of the heat shrink bag 10 onto the welding ring assembly. On the outside of the support rod 2, the support rod fixing part 6 has a fixed state or an open state. When the support rod fixing part 6 is in the fixed state, its fixed end abuts against the heat shrink bag 10 and abuts the heat shrink bag 10 against the support rod 2. The support rod 2 and the heat shrink bag 10 are relatively fixed and will not move. At this time, the traction component 3 and the driven part 51 will not move. When the support rod fixing part 6 is in the open state, its fixed end is no longer in contact with the heat shrink bag 10 and is spaced apart from the heat shrink bag 10. In this state, the heat shrink bag 10 can move relative to the support rod 2 along the collar rod 9 under the drive of the traction component 3. At this time, even if the support rod 2 is not fixed by the support rod fixing part 6, the support rod 2 will be abutted by the collar rod 9, and the support rod 2 will not move towards the collar rod 9 along the axial direction of the collar rod 9. However, in embodiments where the traction assembly 3 is set in two groups, and both groups of traction assemblies 3 include a rotating motor and a rotating component 33, the bag support rod fixing part 6 may not be provided. The bag support rod 2 can be fixed axially by the radial clamping of the two rotating components 33. Of course, the preferred method is to also provide the bag support rod fixing part 6 in these embodiments to further fix the bag support rod 2.

[0030] Specifically, such as Figure 3As shown, in this embodiment, the cutting assembly 4 includes a second clamping cylinder 41 and scissors 42. The scissors 42, driven by the second clamping cylinder 41, cut the heat shrink bag 10. The bag support rod fixing part 6 includes a third clamping cylinder 61 and a bag support rod clamping block 62. Driven by the third clamping cylinder 61, the bag support rod clamping block 62 approaches the bag support rod 2 to clamp the bag support rod and the heat shrink bag 10 located outside the bag support rod 2 into a single unit, preventing relative movement and thus fixing the bag support rod 2. At this time, the collar rod 9 can move to other positions without contacting the bag support rod 2. Of course, when the traction assembly 3 pulls the heat shrink bag 10, the bag support rod clamping block 62 is under the influence of the third clamping cylinder 61. Driven away from the support rod 2, the support rod 2 is no longer fixed. It should be noted that by setting the clamping force of the clamping cylinder in the support rod fixing part 6 and the traction assembly 3, the two support rod clamping blocks 62 in the support rod fixing part 6 can fix the heat shrink bag 10 to the support rod 2 together. After clamping the outer wall of the heat shrink bag 10, the two abutting traction blocks 32 in the traction assembly 3 drive the heat shrink bag 10 to move towards the welding ring assembly along the axial direction of the collar rod 9 through friction, and finally put the welding ring assembly inside. Of course, in some other embodiments, the above-mentioned clamping cylinder can also be replaced by other devices, such as two linear cylinders driving one clamping block to move or a gear and rack mechanism, etc.

[0031] In this embodiment, the collar rod 9 is axially slidably mounted on the turntable 12 inside the mounting box, and the turntable 12 can drive the collar rod 9 to move to other work positions. In order to achieve the axial movement of the collar rod 9, such as... Figure 6 As shown, a first abutment plate 14 is provided on the radially outer side wall of the collar rod 9. A reset member 16 is provided between the first abutment plate 14 and the turntable 12. The reset member 16 is sleeved on the outside of the collar rod 9. A power member 13 is provided on the side of the collar rod 9 that is axially away from the support rod 2. A second abutment plate 15 is provided at the end of the power member 13. The power member 13 can drive the second abutment plate 15 to axially approach and abut against the collar rod 9, so that the collar rod 9 approaches and abuts against the support rod 2 axially. The reset member 16 is compressed. The power member 13 drives the second abutment plate 15 to move away from the collar rod 9 axially. Under the action of the reset member 16, the collar rod 9 moves away from the support rod 2 axially, thereby realizing the axial movement of the collar rod 9. The power member 13 can be a linear cylinder, and the reset member 16 can be a spring.

[0032] In this embodiment, the complete workflow of the welding ring bagging mechanism is as follows: First, the heat shrink bag 10 is placed on the outside of the support rod 2. When bagging, the collar rod 9 abuts against the support rod 2. The support rod fixing part 6 removes its fixation on the heat shrink bag 10 and the support rod 2. The traction end of the traction component 3 approaches and abuts against the heat shrink bag 10. As the cutting component 4 and the traction component 3 move axially towards the collar rod 9 along with the driven part 51, the traction end of the traction component 3 uses friction to make the heat shrink bag 10 move relative to the support rod 2. The heat shrink bag 10 moves axially towards the collar rod 9 until the welding ring placed on the outside of the collar rod 9. Outside the assembly, the traction end of the traction component 3 no longer abuts against the heat shrink bag 10, and the abutment force on the heat shrink bag 10 is released. Subsequently, the cutting component 4 and the traction component 3 move away from the collar rod 9 along the driven part 51 to their original positions. After the cutting component 4 is reset, it cuts the heat shrink bag 10, so that the heat shrink bag 10 sleeved on the outside of the welding ring assembly is removed. The cutting component 4 and the heat shrink bag 10, which are in their original positions, wait for the next bagging. During the interval between two bagging, the bag support rod fixing part 6 continues to fix the heat shrink bag 10 and the bag support rod 2, so that the position of the heat shrink bag 10 and the fixing rod does not move before bagging.

[0033] Specifically, such as Figure 3 As shown, the bag support rod fixing part 6, the traction component 3, and the cutting component 4 are arranged sequentially close to the collar rod 9 along the axial direction of the collar rod 9. The bag support rod fixing part 6 is located on the end of the bag support rod fixing part 6 that is axially away from the collar rod 9. Once the bag is finished, the bag support rod fixing part 6 can restrict the positional movement of the heat shrink bag 10 and the bag support rod 2 by fixing the end of the bag support rod that is axially away from the collar rod 9. The traction end of the traction component 3 is in contact with the middle of the bag support rod 2, providing space for the traction component 3 to move axially. The cutting component 4 is located on the side of the bag support rod 2 that is axially close to the collar rod 9, which can make the cut of the heat shrink bag 10 on the outside of the welding ring group shorter.

[0034] Specifically, in order to ensure that the support rod 2 is stably set along the axial direction of the collar rod 9 and cooperates with the welding ring assembly on the collar rod 9, so that the heat shrink bag 10 can move along the axial direction of the collar rod 9 and be fitted onto the outside of the welding ring assembly, the welding ring bag fitting mechanism also includes a guide assembly 7. The guide assembly 7 includes a guide mounting plate 71 and a guide plate assembly 72. The guide mounting plate 71 is mounted on the mounting box, wherein the aforementioned support rod fixing part 6 is mounted on the mounting box through the guide mounting plate 71. The guide plate assembly 72 has a guide channel set along the axial direction of the collar rod 9. The support rod 2 passes through the guide channel along the axial direction of the collar rod 9. The two ends of the support rod 2 are respectively located on the two outer sides of the guide channel, thereby achieving radial limitation of the support rod 2, so that the heat shrink bag 10 can only pass through the radial inner wall of the guide channel along the axial direction.

[0035] Specifically, in this embodiment, such as Figures 7-8As shown, the guide assembly 7 includes two guide plates 721, which are spaced apart along the axial direction of the collar rod 9. The limiting plate is provided with guide holes 7211 along the axial direction of the collar rod 9. The two guide holes 7211 are coaxially arranged and form a guide channel. The two ends of the bag support rod 2 pass through the two guide holes 7211 to the outside, which can limit the radial movement of the bag support rod 2. The middle position of the bag support rod 2 is not limited and is exposed, so the overall weight of the guide assembly 7 can be greatly reduced. Furthermore, in order to ensure a good radial limiting effect of the guide channel on the support rod 2, the radial gap between the guide channel and the support rod 2 should not be too large. In addition, to match different support rods 2, heat shrink bags 10 of different sizes, and welding ring assemblies of different sizes, a guide ring 722 is provided in the guide hole 7211. The guide ring 722 is fixed by multiple screws on the radial sidewall of the guide plate 721, and the support rod 2 passes through the guide ring 722 to limit the radial dimension of the collar rod 9. Therefore, the radial dimension of the welding ring assembly can be matched by changing the size of the guide ring 722, the size of the support rod 2, and the size of the heat shrink bag 10, which improves practicality.

[0036] In other embodiments, the guide plate assembly 72 can be composed of multiple guide plates 72 arranged axially along the collar rod 9. The multiple guide plates 721 are circumferentially distributed and form a guide channel, and there is a gap between the multiple guide plates 721, so that the fixing end of the bag support rod fixing part 6 and the traction end of the traction assembly 3 can be inserted and abut against the heat shrink bag 10 sleeved on the outer periphery of the bag support rod 2.

[0037] Specifically, a guide rod 8 is provided on the axial side of the end of the bag support rod 2 away from the collar rod 9. The guide rod 8 and the bag support rod 2 are positioned along the axial direction of the collar rod 9. The heat shrink bag 10 on the roll bag assembly 1 is wrapped around the outside of the guide rod 8. The heat shrink bag 10 extends axially through the guide rod 8 to the bag support rod 2 and is sleeved on the outside of the bag support rod 2, ensuring the stability of the heat shrink bag 10 sleeved on the outside of the bag support rod 2. The guide rod 8 is rotatably set, which reduces the friction between the heat shrink bag 10 and the guide rod 8, and prevents the outside of the heat shrink bag 10 from being worn.

[0038] Specifically, such as Figures 9-10As shown, the roll bag assembly 1 includes a roll bag shaft 101 and two abutment portions 102. The two abutment portions 102 are spaced apart along the axial direction of the roll bag shaft 101. The heat shrink bag 10 is sleeved on the roll bag shaft 101 and located between the two abutment portions 102. To facilitate the replacement of the heat shrink bag 10 and to provide a certain pre-tightening force when the heat shrink bag 10 rotates on the roll bag shaft 101, the subsequent traction assembly 3 provides greater stability when traction is applied to the heat shrink bag 10. Furthermore, when not traction is applied, the heat shrink bag 10 itself will not rotate, allowing the abutment portions 102 to be inserted axially into the roll bag shaft 101. On the outer side, the abutment portion 102 can slide along the roll shaft 101. An elastic element 103 is sleeved on the roll shaft 101 outside the abutment portion 102. One end of the elastic element 103 abuts against the abutment portion 102, and the other end abuts against a nut on the roll shaft 101. Thus, under the action of the elastic element 103, the two abutment portions 102 can abut the heat shrink bag 10 against the roll shaft 101. Under the action of external traction force, the heat shrink bag 10 can rotate around the roll shaft 101, allowing it to be released. After the external traction force is removed, the heat shrink bag 10 will stop rotating. The elastic element 103 can be a spring. Specifically, the abutment portion 102 can be configured as an annular plate.

[0039] Specifically, the roll-up shaft 101 and the guide rod 8 are both mounted on the mounting box via the roll-up mounting frame 11. The roll-up shaft 101 and the guide rod 8 are rotatably mounted on the roll-up mounting frame 11. By adjusting the relative positions of the roll-up shaft 101 and the guide rod 8 on the roll-up mounting frame 11, the exit direction of the heat shrink bag 10 can be adjusted, so that after being guided by the guide rod 8, the heat shrink bag 10 is axially oriented towards the support rod 2. It should be noted that the initial placement of the heat shrink bag 10 on the outside of the support rod 2 requires manual operation. During the entire bagging mechanism operation, the heat shrink bag 10 completely covers the support rod 2, and the opening of the heat shrink bag 10 is located at the end of the support rod 2 axially close to the collar rod 9, so that the heat shrink bag 10 can be placed on the outside of the welding ring assembly more quickly, improving the bagging efficiency.

[0040] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
