Description

Technical Field

[0001] This utility model relates to the field of welding ring packaging technology, and in particular to a welding ring packaging device. Background Technology

[0002] Ordinary packaging bags are generally used for sealing, and there is a gap between the welding ring and the packaging bag. During transportation, due to bumps, the welding ring may also become interlocked, requiring the ring to be removed before use, resulting in a poor user experience. Utility Model Content

[0003] This utility model provides a welding ring packaging equipment, which uses a turntable, a thermoplastic tube and a driven platform to perform thermoplasticizing on the heat shrink bag on the outside of the welding ring assembly in a highly efficient and automated manner, with high thermoplasticizing efficiency.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A ring-welding packaging equipment, comprising an upper ring station, a bagging station, a thermoplastic station, and a lower ring station, including: an installation box; A turntable mechanism is provided in the mounting box. The turntable mechanism includes a rotatable turntable. The turntable is provided with at least four collar rods distributed along its circumference, so that when one of the collar rods corresponds to the upper ring station, the other three collar rods are respectively set to correspond to the bagging station, the thermoplastic station and the lower ring station. A thermoplastic tube, arranged axially along the collar rod, is used to thermoplasticize the bagged welding ring assembly on the collar rod at the thermoplastic station. A drive assembly is provided in the mounting box. The drive assembly includes a driven platform that moves axially along the collar rod. The thermoplastic tube is provided on the driven platform so that it moves along the collar rod axially with the driven platform, approaches and is sleeved on the outside of the collar rod.

[0005] Preferably, the thermoplastic tube includes at least two thermoplastic sub-tubes that can be heated and a connecting tube, and two adjacent thermoplastic sub-tubes are coaxially connected through the connecting tube.

[0006] Preferably, both the connecting pipe and the thermoplastic sub-pipe are provided with ring plates on their radial outer sides, and multiple ring plates are connected axially.

[0007] Preferably, the thermoplastic tube includes a single thermoplastic sub-tube that can be heated, and the axial length of the thermoplastic sub-tube along the collar rod is not less than the axial length of the welding ring assembly along the collar rod.

[0008] Preferably, the end of the thermoplastic tube away from the collar rod along the axial direction is connected to a smoke guide tube to exhaust the smoke generated by the outer packaging bag of the thermoplastic welded ring assembly inside the thermoplastic tube.

[0009] Preferably, it further includes an air blowing component, and when the thermoplastic tube is sleeved on the outside of the welding ring assembly, the air blowing port of the air blowing component is located at the opening of the thermoplastic tube axially away from the smoke guide tube.

[0010] Preferably, it further includes a lower ring mechanism corresponding to the lower ring station. The lower ring mechanism is located on the driven platform so that it moves along the axial direction of the collar rod with the driven platform, approaches and clamps the thermoplastic welded ring assembly on the collar rod, and disengages the thermoplastic welded ring assembly from the collar rod when it moves away from the collar rod.

[0011] Preferably, the lower ring mechanism includes a rotating clamping part and two clamping blocks. The two clamping blocks are located at the output end of the rotating clamping part so that the two clamping blocks can approach each other to clamp the thermoplastic welded ring assembly at the lower ring station, and can rotate to turn the clamped thermoplastic welded ring assembly.

[0012] Preferably, it also includes a sampling inspection mechanism, which is located outside the upper ring workstation; The sampling mechanism includes a sampling box and a reciprocating drive component. The reciprocating drive component is connected to the sampling box so that when there is no collar rod at the upper ring station, the sampling box moves to the upper ring station to collect the welding ring.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. Thermoplastic packaging of the outer heat-shrink bag of the welding ring assembly with thermoplastic tubing can limit the welding rings inside the assembly, preventing them from moving and becoming interlocked during transportation, thus facilitating subsequent use by the user.

[0014] 2. The turntable can drive the collar rod to move between the upper ring station, the bagging station, the thermoforming station, and the lower ring station. In conjunction with the thermoforming tube driven by the driven platform, it can move closer to or away from the collar rod at the thermoforming station along the collar rod axis, realizing automated thermoforming of the heat-shrinkable bag outside the welding ring assembly. Moreover, the entire process is carried out by the turntable to transport the welding ring assembly, making the thermoforming packaging efficiency of the entire welding ring higher.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

[0021] The welding ring packaging equipment 100 is used for loading, packaging, thermoforming, and unloading welding rings. It has an loading station 8, a bagging station 9, a thermoforming station 10, and an unloading station 11. The loading station 8 is used for loading welding rings, the bagging station 9 is used for bagging welding rings, the thermoforming station 10 is used for thermoforming the packaged welding rings, and the unloading station 11 is used for unloading the packaged and thermoformed welding rings. The process is repeated until the welding ring thermoforming packaging is completed. In order to increase the thermoforming efficiency of welding ring thermoforming packaging, this utility model embodiment provides a welding ring packaging equipment 100, which specifically includes a turntable mechanism 2, a thermoforming tube 3, and a drive assembly 4. The thermoforming packaging of welding rings is realized through the cooperation of the turntable mechanism 2, the thermoforming tube 3, and the drive assembly 4.

[0022] like Figure 1As shown, the turntable mechanism 2 includes a turntable 21, which can rotate circumferentially around its own axis. A collar rod 22 is provided on the turntable 21 for transferring welding rings. Multiple welding rings are sleeved on the collar rod 22 to form an axially arranged welding ring group. The radial inner wall of the welding ring group is clearance-fitted with the radial outer wall of the collar rod 22, allowing the welding ring group to disengage from the collar rod 22. The turntable 21 can rotate circumferentially, and the collar rod 22 can rotate circumferentially with the turntable 21, so that the collar rod 22 can sequentially transfer welding rings. The device rotates between the upper ring station 8, the bagging station 9, the thermoplastic station 10, and the lower ring station 11 to perform ring welding, packaging, thermoplasticizing, and lowering. The thermoplastic tube 3 is axially positioned along the collar rod 22 and is used in conjunction with the drive assembly 4. The drive assembly 4 specifically includes a driven platform 42, which can move axially along the collar rod 22. This allows the thermoplastic tube 3 to move axially along the collar rod 22, bringing it closer to the collar rod 22 and fitting it onto the outside of the collar rod 22 at the thermoplastic station 10. The weld ring assembly with the heat-shrink bag on the collar rod 22 undergoes thermoplastic treatment, causing the heat-shrink bag to adhere to the outer circumference of the weld ring assembly. After the thermoplastic treatment is completed, the thermoplastic tube 3 moves away from the collar rod 22 along the axial direction of the driven platform 42, and the thermoplastic weld ring assembly is detached from the thermoplastic tube 3. Subsequently, the turntable 21 can drive the collar rod 22 to continue rotating to the lower ring station 11 to perform the lower ring treatment on the thermoplastic weld ring assembly. It should be noted that the thermoplastic treatment can be set for a certain time, specifically according to the heat... The specific process for the plastic processing personnel depends on their usual thermoplastic experience; the turntable 21 rotates the collar rod 22 to each station and works in conjunction with the thermoplastic tube 3, which can move axially along the collar rod 22 to thermoplasticize the heat shrink bag outside the welding ring assembly. This allows for automated thermoplastic processing of the welding ring assembly, limits the position of the packaged welding ring, and ensures the thermoplastic effect by limiting the welding ring when it is fitted onto the collar shaft and thermoplasticized by the thermoplastic tube 3, preventing radial movement that could affect the adhesion of the thermoplastic film to the outer wall of the welding ring.

[0023] In this embodiment, such as Figures 2-3 As shown, there are four collar rods 22, which are evenly distributed around the turntable 21. The four collar rods 22 are respectively set at the upper ring station 8, the bagging station 9, the thermoforming station 10, and the lower ring station 11. When one collar rod 22 is located at the upper ring station 8, the other three collar rods 22 are located at the bagging station 9, the thermoforming station 10, and the lower ring station 11, so that each station is performing the corresponding work, so that the welding ring can be continuously put on, bagged, thermoformed, and lowered, ensuring the thermoforming packaging efficiency of the welding ring. There can be more than four collar rods 22, but the preferred method is to set four collar rods 22.

[0024] Specifically, in this embodiment, such as Figure 4As shown, the thermoplastic tube 3 includes at least two heat-generating thermoplastic sub-tubes 31 and multiple connecting tubes 32. Two adjacent thermoplastic sub-tubes 31 are coaxially connected through the connecting tubes 32 to form a complete thermoplastic tube 3. The thermoplastic sub-tubes 31 can be existing ceramic heating tubes, which are small in size, have high power, fast heating speed, and long service life. The connecting tubes 32 can be ordinary metal tubes. When the thermoplastic tube 3 is thermoplasticized, the thermoplastic sub-tubes 31 are energized and heated. The heat radiation generated by them will be dissipated to the adjacent connecting tubes 32, so that the connecting tubes 32 can also be heated. This ensures that after the thermoplastic tube 3 is sleeved on the outside of the collar rod 22, the entire thermoplastic tube 3 can heat the heat shrink bag outside the welding ring assembly, ensuring the thermoplastic effect.

[0025] Specifically, both the connecting pipe 32 and the thermoplastic sub-pipe 31 are provided with annular plates 33 at their axial ends. The annular plates 33 at the axial end of the connecting pipe 32 abut against the annular plates 33 at the axial end of the thermoplastic sub-pipe 31, so that the connecting pipe 32 and the thermoplastic sub-pipe 31 are connected. A connecting rod 34 is provided axially, and the connecting rod 34 passes through multiple annular plates 33 axially. The two axial end faces of the annular plates 33 are abutted and limited by nuts on the connecting rod 34, connecting multiple annular plates 33 into a whole, so that the connecting pipe 32 and the thermoplastic sub-pipe 31 are connected to form a thermoplastic pipe 3. There are multiple connecting rods 34, which are evenly distributed along the circumference of the thermoplastic sub-pipe 31.

[0026] In some other embodiments, the thermoplastic tube 3 also includes a thermoplastic sub-tube 31, which can be an existing ceramic heating tube. The length of the thermoplastic sub-tube 31 along the axial direction of the collar rod 22 is not less than the axial length of the welding ring assembly along the collar rod 22, so that the thermoplastic sub-tube 31 can completely cover the welding ring assembly and perform thermoplastic treatment on the heat shrink bag outside the welding ring assembly.

[0027] Specifically, such as Figure 4 As shown, a smoke guide pipe 5 is connected to the end of the thermoplastic tube 3 away from the collar rod 22 along the axial direction. The smoke guide pipe 5 is used to guide the fumes generated during the thermoplasticization of the thermoplastic tube 3 to the external area, so as to avoid the situation where the fumes are discharged from the thermoplastic tube 3 and contaminate the thermoplastic area. The angle between the smoke guide pipe 5 and the axis of the thermoplastic tube 3 can be any angle. Furthermore, an air extraction device is provided at the end of the smoke guide pipe 5 away from the thermoplastic tube 3. The air extraction device can be a vacuum pump, which can quickly extract the fumes from the thermoplastic tube 3 to prevent the fumes from leaking from the thermoplastic tube 3.

[0028] Specifically, the thermoplastic mechanism also includes an air blowing component, which can be an air nozzle connected to the air passage. When the thermoplastic tube 3 moves axially along the collar rod 22 with the driven platform 42 and fits the welding ring assembly on the collar rod 22 at the thermoplastic station 10, the air nozzle is located at the opening of the thermoplastic tube 3 away from the smoke guide pipe 5. After the thermoplastic process is completed, the air nozzle blows air to quickly blow the smoke in the thermoplastic tube 3 into the smoke guide pipe 5 and discharge it. In addition, the air nozzle, together with the above-mentioned air extraction device, can discharge the smoke in the thermoplastic tube 3 more quickly.

[0029] Specifically, such as Figure 5 As shown, the drive assembly 4 also includes a power unit 41, which is mounted on the mounting box 1. The driven platform 42 is connected to the power unit 41. Driven by the power unit 41, the driven platform 42 can reciprocate along the axial direction of the collar rod 22. Specifically, the power unit 41 can be one of the following: a screw mechanism, a combination of a linear motor and a sliding block, or a single linear motor.

[0030] Specifically, the turntable mechanism 2 also includes a transfer drive unit 23 that enables the turntable 21 to rotate circumferentially along its own axis. For example, the transfer drive unit 23 can be a combination of a rotating motor and gears. An external gear ring is provided at the lower part of the turntable 21. The rotating motor drives the external gear ring through the gears, thereby driving the turntable 21 to rotate. Of course, the transfer drive unit 23 is not limited to the above-mentioned structure.

[0031] Specifically, such as Figure 5 As shown, the welding ring packaging equipment 100 also includes a lower ring mechanism 6, which is set at the lower ring station 11. The lower ring mechanism 6 can clamp and lower the welding ring group that has been thermoplastic packaged at the lower ring station 11. The lower ring mechanism 6 is set on the driven platform 42 and can reciprocate along the collar rod 22 along the driven platform 42. When the turntable 21 moves to the lower ring station 11 with the welding ring group that has been thermoplastic packaged, the lower ring mechanism 6 moves closer to and to the collar rod 22 along the driven platform 42. The clamping end of the lower ring mechanism 6 is located outside the welding ring group that has been thermoplastic packaged. The clamping end of the lower ring mechanism 6 abuts against the outer wall of the welding ring group and clamps the welding ring group. Then, the lower ring mechanism 6 moves away from the collar rod 22 along the driven platform 42 along the collar rod 22. The welding ring group is then released from the collar rod 22 under the clamping of the lower ring mechanism 6, and the lower ring is completed on the collar rod 22.

[0032] Specifically, the lower ring mechanism 6 includes a rotating clamping part 61 and two clamping blocks 62. The two clamping blocks 62 are located at the output end of the rotating clamping part 61. When the lower ring mechanism 6 is transported to the outside of the collar rod 22, the rotating clamping part 61 causes the two clamping blocks 62 to approach and abut against the outer wall of the weld ring assembly, clamping the weld ring assembly. Subsequently, the lower ring mechanism 6 moves axially away from the collar rod 22 along with the driven platform 42 and resets. The two clamping blocks 62 clamp the weld ring assembly and disengage it from the collar rod 22. Then, the rotating clamping part 61 can rotate, causing the clamped thermoplastic weld ring assembly to rotate a certain angle. The two clamping blocks 62 move away from each other, releasing the weld ring assembly and completing the lower ring operation. It should be noted that, as Figure 7 As shown, the mounting box 1 has a lower ring channel 101 corresponding to the lower ring mechanism 6. The lower ring mechanism 6 will rotate the clamping block 62 to the lower ring channel 101, causing the welding ring assembly to tilt towards the lower ring channel 101, and then release the welding ring assembly so that it can fall into the lower ring channel 101. The rotating clamping part 61 is set as a rotating clamping cylinder, but it can also be other rotating clamping devices or driving components.

[0033] Specifically, the clamping block 62, which is far from the lower ring channel 101, is provided with at least two limiting posts 63. The limiting posts 63 are arranged along the axial direction of the collar rod 22. After the clamping block 62 clamps the welding ring assembly, the two limiting posts 63 abut against the outer wall of the welding ring assembly, which can provide a longer radial limit along the axial direction of the collar rod 22. Moreover, when the lower ring is lowered, when the rotating clamping part 61 rotates at a certain angle, the welding ring assembly tilts towards the lower ring channel 101. The two limiting posts 63 guide the welding ring assembly, so that it can slide stably along the limiting posts 63 and the side wall of the clamping block 62 towards the lower ring channel 101. The welding ring assembly can fall stably to the lower ring channel 101.

[0034] Specifically, such as Figure 6 As shown, the welding ring packaging equipment 100 also includes a sampling inspection mechanism 7, which is located outside the ring-up station 8. When the ring-up station 8 needs to perform normal ring-up, the sampling inspection mechanism 7 does not operate. When a certain number of rings are installed, the ring-up rod 22 at the ring-up station 8 rotates with the turntable 21 to a certain angle, and there is no ring-up rod 22 at the ring-up station 8. At this time, the sampling end of the sampling inspection mechanism 7 moves to the ring-up station 8 to collect the welding rings. After a certain number are collected, the sampling end of the sampling inspection mechanism 7 exits the ring-up station 8, the turntable 21 continues to rotate, and the ring-up rod 22... As the turntable 21 rotates to the upper ring station 8 for ring mounting, it is important to know that when the sampling inspection mechanism 7 needs to collect the weld rings, the collar rod 22 at the upper ring station 8 only needs to rotate a certain angle so that there is no collar rod 22 at the upper ring station 8, providing space for the sampling end of the sampling inspection mechanism 7 to enter the upper ring station 8. However, the collar rod 22 at the upper ring station 8 cannot rotate to the next station, because if it rotates to the next station, another collar rod 22 will move with the turntable 21 to the upper ring station 8 and interfere with the sampling end of the sampling inspection mechanism 7 entering the upper ring station 8.

[0035] Specifically, such as Figure 6 As shown, the sampling inspection mechanism 7 includes a sampling box 71 and a reciprocating drive 72. The sampling box 71 is configured as a guide box with a guide channel. The reciprocating drive 72 is mounted on the mounting box 1 and connected to the sampling box 71, causing the sampling box 71 to reciprocate. Driven by the reciprocating drive 72, the sampling box 71 can move from outside the upper ring station 8 to the upper ring station 8 to collect the welding rings. After collection, it moves from the upper ring station 8 back to its original position, as shown. Figure 8 As shown, the mounting box 1 is provided with a sampling material output channel 102. The bottom opening of the sampling box 71 near the sampling material output channel 102 is connected to the sampling material output channel 102. The welding ring enters the sampling material output channel 102 through the sampling box 71. The reciprocating drive component 72 can be a linear cylinder or a linear motor.

[0036] It is important to know that at the upper ring station 8, the welding ring can be manually placed onto the collar rod 22. At the bagging station 9, the heat shrink bag can be manually placed onto the outside of the welding ring assembly. Alternatively, the upper ring station 8 has a corresponding ring-guiding mechanism that automatically places the welding ring onto the collar rod 22 to form the welding ring assembly. The bagging station 9 is equipped with a bagging mechanism that automatically places the heat shrink bag onto the outside of the welding ring assembly and automatically cuts it, so that the welding ring assembly on the collar rod 22 can be bagged and ready for the next step of thermoplastic processing.

[0037] 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.
