Description

Technical Field

[0001] This utility model relates to the field of rotating mechanism technology, and in particular to a welding machine handle rotating mechanism. Background Technology

[0002] In the field of plastic product processing, plastic welding machines are essential equipment for joining plastic components. By heating the welding end of a plastic rod with a heating plate, the end of the rod melts, thus achieving a strong weld with other components. The quality of this weld directly affects the overall performance and service life of the plastic product.

[0003] However, existing plastic welding machines have significant drawbacks in actual operation. When the heating plate heats the welding end of the plastic rod, the operator must constantly hold the heating plate to prevent it from slipping off the end of the rod. This method not only consumes a lot of manpower, increases the operator's workload, and reduces work efficiency, but also causes hand fatigue due to prolonged holding of the heating plate. This can lead to misalignment between the heating plate and the end of the plastic rod, affecting welding quality, resulting in weak welds, uneven weld surfaces, and other problems, increasing product defect rates and production costs. Therefore, this invention proposes a welding machine handle rotation mechanism. Utility Model Content

[0004] The purpose of this invention is to address the problems of existing plastic welding machines in the background art, which require continuous manual support of the heating plate during the heating and welding process, resulting in high labor costs, low work efficiency, poor welding quality, and high production costs. This invention proposes a welding machine handle rotation mechanism.

[0005] The technical solution of this utility model is as follows: A welding machine handle rotation mechanism includes a welding machine body, a side plate disposed on one side of the welding machine body, and a vertical plate fixedly connected to the top of the welding machine body; a rotating shaft rotatably connected between the side plate and the vertical plate, a fixed wall fixedly connected to the outer ring of the rotating shaft, and a heating plate installed on the fixed wall; a driving mechanism disposed at one end of the rotating shaft, the driving mechanism being used to rotate the rotating shaft to adjust the position of the heating plate; a locking mechanism installed on the side of the vertical plate, the locking mechanism being used to lock the position of the heating plate when heating; and a buffer assembly, the buffer assembly being used to buffer when the heating plate falls.

[0006] Optionally, the drive mechanism includes a rotating sleeve fixedly connected to the end of the rotating shaft away from the side plate, and a handle is fixedly connected to the rotating sleeve.

[0007] Optionally, the rotating sleeve is equipped with two sets of limiting baffles at the end away from the side plate, and the upright plate is provided with a mounting plate installed on the top of the welding machine body on the side away from the side plate. Two sets of micro switches are installed on the side of the mounting plate close to the upright plate.

[0008] Optionally, the locking mechanism includes a fixed shaft fixedly connected to the side of the upright plate away from the side plate, a locking plate rotatably connected to the fixed shaft, a locking groove being provided on the side of the locking plate near the rotating sleeve, and a slot corresponding to the locking groove being provided on the side of the rotating sleeve.

[0009] Optionally, the locking mechanism further includes a miniature push rod rotatably connected to the side of the upright plate away from the side plate. The output end of the miniature push rod has a connecting groove, and a plug rod is installed in the connecting groove. One end of the locking plate is located in the connecting groove and rotatably connected to the plug rod.

[0010] Optionally, the buffer assembly includes a fixing block fixedly connected to the side of the upright plate near the side plate, a spring sheet is installed on the fixing block near the rotating shaft, and a cam is sleeved on the rotating shaft at a position corresponding to the spring sheet.

[0011] Optionally, the spring is V-shaped, and a damper is installed in the fixing block, with one end of the damper facing the spring.

[0012] In summary, this application includes at least one of the following beneficial technical effects:

[0013] This utility model, through the linkage design of the handle, rotating sleeve and rotating shaft in the drive mechanism, allows the operator to easily rotate the heating plate to the target position. With the precise positioning mechanism of the micro switch triggered by the limit baffle, there is no need for continuous manual support of the heating plate. At the same time, the micro push rod in the locking mechanism drives the locking plate to engage with the groove of the rotating sleeve, forming a mechanical lock. This completely avoids positional deviation caused by human intervention during the heating process, improves the welding position accuracy, and significantly reduces the intensity of manual labor.

[0014] Furthermore, through the combined design of the spring sheet and damper in the buffer assembly, when the heating plate falls, the cam first squeezes the spring sheet to achieve primary buffering, and then compresses the damper top rod to achieve secondary damping and deceleration. This can reduce the falling impact speed, effectively avoid hard collision between the heating plate and the welding machine body, reduce the wear rate of related components, and significantly extend the overall service life of the equipment.

[0015] In summary, this utility model effectively reduces labor costs, while improving work efficiency and welding precision, reducing product defect rates, and extending equipment lifespan. Attached Figure Description

[0031] Example

[0032] like Figure 1 and Figure 2 As shown, the present invention proposes a welding machine handle rotation mechanism, including a side plate 11 disposed on one side of the welding machine body 1. The side plate 11 serves as a side support component of the entire rotation mechanism, providing an installation base for other components. A vertical plate 12 is also fixedly connected to the top of the welding machine body 1. The vertical plate 12 serves as a fixed support in the vertical direction and cooperates with the side plate 11 to determine the installation frame of the rotation mechanism. The positions of the side plate 11 and the vertical plate 12 are fixed.

[0033] Furthermore, the aforementioned rotating mechanism includes a rotating shaft 2 rotatably connected between the side plate 11 and the upright plate 12. The rotating shaft 2 can rotate in place within the space defined by the side plate 11 and the upright plate 12, providing a rotation axis for the rotation of the heating plate 4. A fixed wall 3 is fixedly connected to the outer ring of the rotating shaft 2. The fixed wall 3 firmly connects the heating plate 4 and the rotating shaft 2 as one unit. The heating plate 4 is installed on the fixed wall 3. When the rotating shaft 2 rotates, it drives the heating plate 4 to rotate through the fixed wall 3, realizing flexible adjustment of the position of the heating plate 4 to meet different welding position requirements.

[0034] For further details, please refer to Figure 3 and Figure 4The aforementioned rotating mechanism includes a drive mechanism 5 disposed at one end of the rotating shaft 2. The drive mechanism 5 is the power source for adjusting the position of the heating plate 4. The drive mechanism 5 is used to rotate the rotating shaft 2 to adjust the position of the heating plate 4. The drive mechanism 5 includes a rotating sleeve 51 fixedly connected to the end of the rotating shaft 2 away from the side plate 11. The rotating sleeve 51 can effectively transmit the operating force to the rotating shaft 2, driving the rotating shaft 2 to rotate synchronously when rotating. A handle 52 is fixedly connected to the rotating sleeve 51, which is designed to facilitate easy rotation of the rotating sleeve 51 by the operator, reducing the operating intensity. Two sets of limiting baffles 53 are installed at the end of the rotating sleeve 51 away from the side plate 11. The limiting baffles 53 rotate with the rotating sleeve 51 and are used to limit the rotation range of the rotating sleeve 51. When the rotating sleeve 51 rotates, it drives the two sets of limiting baffles 53 to perform circular motion. A mounting plate 54 is installed on the top of the welding machine body 1 on the side of the upright plate 12 away from the side plate 11. Two sets of micro switches 55 are installed on the side of the mounting plate 54 close to the upright plate 12. The micro switches 55 can accurately sense the trigger signal of the limit stop plate 53. When the rotating sleeve 51 rotates, it drives the limit stop plate 53 to trigger the micro switches 55. By sensing the trigger state of the two sets of micro switches 55, the position of the heating plate 4 can be known, which makes it easy to control the heating plate 4 to be in a suitable welding position.

[0035] Specifically, the aforementioned rotating mechanism also includes a locking mechanism 6 installed on the side of the upright plate 12. The locking mechanism 6 effectively prevents the heating plate 4 from shifting due to external force or gravity during heating. The locking mechanism 6 is used to lock the position of the heating plate 4 during heating. The locking mechanism 6 includes a fixed shaft 61 fixedly connected to the side of the upright plate 12 away from the side plate 11. The fixed shaft 61 provides a stable rotation fulcrum for the locking plate 62, and its position is fixed. The locking plate 62 is rotatably connected to the fixed shaft 61. The locking plate 62 can rotate flexibly around the fixed shaft 61 to lock and unlock the rotating sleeve 51 and maintain its original position. The locking plate 62 has a locking groove 63 on the side near the rotating sleeve 51, and the side of the rotating sleeve 51 has a corresponding slot 64. When the locking plate 62 rotates, it is locked in the slot 64 through the locking groove 63, forming a mechanical locking structure to prevent the rotating sleeve 51 from continuing to rotate, thereby effectively preventing the heating plate 4 from falling downwards under the influence of gravity and ensuring stability during the heating process. The locking mechanism 6 also includes a miniature push rod 65 rotatably connected to the side of the upright plate 12 away from the side plate 11. The miniature push rod 65 can provide stable power for the rotation of the locking plate 62. The output end of the miniature push rod 65 is provided with a connecting groove 66, and a plug rod 67 is installed in the connecting groove 66. One end of the locking plate 62 is located in the connecting groove 66 and is rotatably connected to the plug rod 67. After the miniature push rod 65 is started, it drives the locking plate 62 to rotate, realizing automated locking and unlocking operations.

[0036] Furthermore, the aforementioned rotating mechanism also includes a buffer assembly 7. The buffer assembly 7 can effectively absorb the impact force when the heating plate 4 falls, avoiding damage to components and positional displacement caused by the impact. The buffer assembly 7 is used to buffer the falling heating plate 4. The buffer assembly 7 includes a fixing block 71 fixedly connected to the side of the upright plate 12 near the side plate 11. The fixing block 71 provides a mounting carrier for other buffer components, and its position is fixed. A spring piece 72 is installed on the fixing block 71 near the rotating shaft 2. A cam 73 is sleeved on the rotating shaft 2 at a position corresponding to the spring piece 72. The spring piece 72 is V-shaped. When the heating plate 4 falls, it drives the rotating shaft 2 to rotate, thereby driving the cam 73 to rotate and contact the spring piece 72. The spring piece 72 can initially buffer the falling impact force. A damper 74 is installed in the fixing block 71. One end of the damper 74 faces the spring piece 72. After the cam 73 rotates and contacts the spring piece 72, it compresses the top rod of the damper 74. The damping effect of the damper 74 reduces the falling impact speed and further improves the buffering effect.

[0037] In this embodiment, the operator first rotates the handle 52 to drive the rotating sleeve 51 to rotate. Since the rotating sleeve 51 is fixedly connected to the rotating shaft 2, the rotating shaft 2 rotates. The fixed wall 3 is connected to the rotating shaft 2, so when the rotating shaft 2 rotates, it drives the heating plate 4 to rotate through the fixed wall 3, thereby achieving the initial adjustment of the position of the heating plate 4.

[0038] During the rotation of the rotating sleeve 51, the limiting baffle 53 on it moves in a circular motion. When the limiting baffle 53 triggers the micro switch 55 on the mounting plate 54, it can be determined that the heating plate 4 has rotated to the appropriate position, so as to accurately control the heating plate 4 to be in the proper welding position.

[0039] Once the heating plate 4 reaches the desired position, the micro push rod 65 is activated. The plug 67 at the output end of the micro push rod 65 drives the locking plate 62 to rotate around the fixed shaft 61, so that the locking groove 63 on the locking plate 62 is engaged in the slot 64 of the rotating sleeve 51, forming a mechanical lock to prevent the rotating sleeve 51 from rotating, thereby preventing the heating plate 4 from falling downward under the influence of gravity and ensuring the stability of the position of the heating plate 4 during the heating process.

[0040] After welding is completed, the miniature push rod 65 is activated again, causing the locking plate 62 to rotate and releasing the lock on the rotating sleeve 51. The heating plate 4 falls under the influence of gravity. At this time, the rotating shaft 2 rotates accordingly, causing the cam 73 sleeved on it to rotate. The cam 73 contacts the spring 72, which initially buffers the impact force of the fall. Then, the cam 73 continues to rotate, compressing the push rod of the damper 74. Through the damping effect of the damper 74, the impact speed of the falling heating plate 4 is further reduced, completing the buffering process and preventing damage to components and positional displacement caused by the impact.

[0041] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
