[0002] A glass fiber drawing machine is a device used in the field of glass fiber production and processing technology for processing and drawing glass fibers. Existing glass fiber drawing machines are equipped with a loading device, which is a mechanical device that pulls the fiber bundle during the glass fiber drawing process and cooperates with the drawing machine to realize the automatic loading function. The fiber bundle is pulled and wound by the loading device, thereby improving the glass fiber processing efficiency and ensuring the glass fiber processing effect.

[0003] There are various types of existing boarding devices. For example, CN218579330U provides a new type of dual-drive automatic boarding device, which includes a driving motor, a motor connecting sleeve, a sleeve and a sleeve support seat. The housing of the driving motor is connected to the rear end of the sleeve through the motor connecting sleeve. The sleeve support seat is installed on the front end of the sleeve. A gear box is installed. A connecting seat is installed on the sleeve near one end of the gear box. The connecting seat and the sleeve support seat are connected through a protective sleeve. A slow pull roller assembly is installed at the front end of the gear box, and a rocker assembly for assisting boarding is provided on the upper part of the slow pull roller assembly; one end of the transmission shaft is connected to the motor shaft of the driving motor, and the other end passes through the sleeve and the protective sleeve in sequence. After the protective sleeve, it extends into the gear box to drive the slow-pull roller assembly, and the slow-pull assembly includes an active roller and a passive roller. The active roller is connected to the active gear in the gear box through a gear shaft, and the passive roller is connected to the passive gear in the gear box through a telescopic universal coupling. When the device is in use, the rocker arm assembly feeds the glass fiber bundle between the active roller and the passive roller along the direction of the guide rail, and the active roller and the passive roller are engaged, clamped and rotated for traction. After the yarn traction is stable and the yarn diameter reaches the appropriate size, the vertical rocker arm slowly rotates under the drive of the screw motor, so that the vertical rocker arm stands upright, and the yarn is leaned against the winding device to complete the automatic curling and loading.

[0004] Although the above-mentioned on-board device feeds the glass fiber bundle between the active roller and the passive roller through the rocker arm assembly, the rocker arm assembly needs to move along the direction of the guide rail during rotation. However, the length of the horizontal rocker arm in the rocker arm assembly is fixed and the length of the horizontal rocker arm cannot be adjusted. Therefore, when the length of the horizontal rocker arm is too long or too short, it cannot move along the direction of the guide rail, causing certain inconveniences to the operation.

[0005] In order to solve this problem, the utility model provides a rocker mechanism for a glass fiber drawing machine to avoid the occurrence of this problem. Utility Model Content

[0037] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0038] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0039] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments. The present invention provides the following embodiments.

[0040] like Figure 1 as well as Figure 2 As shown, it is a structural schematic diagram of the rocker mechanism in this embodiment. The rocker mechanism in this embodiment is assembled on the boarding device of the glass fiber drawing machine. The glass fiber bundle is swung to between the active roller and the passive roller of the boarding device through the rocker mechanism, and is pulled by the engagement, clamping and rotation of the active roller and the passive roller. The rocker mechanism includes a fixed seat 100, and the surface of the fixed seat 100 is connected to a fixed shell 101. A power mechanism 300 is installed in the fixed shell 101, and a rocker assembly 200 is installed below the fixed seat 100. The power mechanism 300 can drive the rocker assembly 200 to rotate and then swing the glass fiber bundle to between the active roller and the passive roller in the boarding device.

[0041] like Figure 3 as well as Figure 4As shown, in this embodiment, a fixing plate 102 is mounted on the surface of the fixing seat 100, and a driving gear 304 and a passive gear 305 are mounted on the fixing plate 102. In this embodiment, the driving gear 304 is engaged with the passive gear 305, and a positioning block 103 is mounted on the fixing plate 102. The driving gear 304 and the passive gear 305 are mounted in a cavity between the fixing plate 102 and the positioning block 103. In addition, a connecting plate 104 is connected to the surface of the fixing plate 102. The connecting plate 104 and the fixing plate 102 are hollow, and a tooth plate 303 is engaged with the driving gear 304, and the tooth plate 303 extends to the outside of the connecting plate 104. And it is slidably assembled with the connecting plate 104. In this embodiment, a driving motor 301 is installed on the surface of the fixed base 100, and the power end of the driving motor 301 is connected to the screw rod 302. The driving motor 301 can drive the screw rod 302 to rotate, and the tooth plate 303 is threadedly assembled on the screw rod 302. The rotation of the screw rod 302 can drive the tooth plate 303 to move along the length direction of the screw rod 302. In this embodiment, when the tooth plate 303 moves, it can drive the driving gear 304 to rotate. Since the driving gear 304 is engaged with the driven gear 305, the rotation of the driving gear 304 can drive the driven gear 305 to rotate.

[0042] It is worth noting that, in this embodiment, the inner diameter of the driving gear 304 is larger than the inner diameter of the driven gear 305 . Therefore, when the toothed plate 303 moves, it drives the driving gear 304 to rotate without interfering with the driven gear 305 .

[0043] like Figure 5 As shown, in this embodiment, the passive gear 305 is equipped with a connecting shaft, which extends to the bottom of the fixed seat 100 and is connected to the clamping assembly 105. The rocker assembly 200 is installed on the clamping assembly 105, and the clamping assembly 105 is clamped on the connecting shaft. Therefore, the passive gear 305 can drive the connecting shaft to rotate during its rotation, and then drive the rocker assembly 200 to rotate in the horizontal direction through the clamping assembly 105, so that the rocker assembly 200 moves along the guide rail direction on the vehicle device, so that the glass fiber bundle swings between the active roller and the passive roller for traction.

[0044] like Figure 6 As shown, it is a schematic structural diagram of the clamping assembly 105 in this embodiment. The clamping assembly 105 in this embodiment is provided with a through hole 105a, and the connecting shaft enters the through hole 105a. The clamping assembly 105 is provided with a locking groove 105b, which is communicated with the through hole 105a. A bolt hole is provided on the side wall of the clamping assembly 105, and a bolt is installed in the bolt hole. The gap of the locking groove 105b is reduced by the action of the bolt so that the connecting shaft can be clamped. In addition, as shown in FIG. Figure 6As shown, the clamping assembly 105 is further provided with an open groove 105c, which is communicated with the through hole 105a. When the clamping assembly 105 is tightened by bolts, the setting of the open groove 105c cooperates with the locking effect, so that the clamping assembly 105 can be tightly locked on the connecting shaft.

[0045] In this embodiment, in order to make the swing arm assembly 200 adjustable to adapt to the guide rail radius of the vehicle boarding device, the length of the swing arm assembly 200 in this embodiment is adjustable, such as Figure 7 As shown, the rocker arm assembly 200 in this embodiment includes a rocker arm seat 201 and a horizontal rocker arm 202. In this embodiment, the interior of the rocker arm seat 201 is hollow and one end of the rocker arm seat 201 is open. One end of the horizontal rocker arm 202 is fixedly connected to a sliding plate 202a, and the sliding plate 202a is slidably assembled in the rocker arm seat 201. In this embodiment, threaded holes are provided on the rocker arm seat 201 and the sliding plate 202a, and the sliding plate 202a can be fixed relative to the rocker arm seat 201 by bolts. In this embodiment, when adjusting the length of the rocker arm assembly 200, the sliding plate 202a is made to slide relative to the rocker arm seat 201 by pulling the horizontal rocker arm 202. When the length of the rocker arm assembly 200 is adjusted, the sliding plate 202a and the rocker arm seat 201 are locked relatively by bolts.

[0046] In this embodiment, the length of the rocker assembly 200 is adjustable, so that the rocker assembly 200 can adapt to the radius of the guide rail in the vehicle-boarding device, thereby improving the practicality of the rocker assembly 200.

[0047] In addition, if Figure 8 as well as Figure 9 As shown, it is a structural diagram of another embodiment of the rocker assembly 200 in this embodiment. Figure 8 As shown, the rocker assembly 200 in this embodiment includes a rocker seat 201 and a horizontal rocker 202. A slide groove 201a is provided on the rocker seat 201, and a sliding block 203 is installed in the slide groove 201a. The sliding block 203 is connected to the horizontal rocker 202 through a connecting mechanism, and a fixing ear is installed on the sliding block 203. The fixing ear is attached to the surface of the rocker seat 201, and bolt holes are provided on the fixing ear and the rocker seat 201, and the sliding block 203 is fixed relative to the rocker seat 201 by bolts.

[0048] It is worth noting that the sliding block 203 in this embodiment moves through the connecting mechanism to drive the horizontal rocking arm 202 to move relative to the rocking arm seat 201, thereby adjusting the length of the rocking arm assembly 200. In order to prevent the horizontal rocking arm 202 from rotating, a guide rod 202b is installed on the horizontal rocking arm 202 in this embodiment, and limiting rings are installed on both sides of the rocking arm seat 201, and the guide rod 202b is slidably assembled on the limiting rings. In this embodiment, the sliding block 203 moves through the connecting mechanism to drive the horizontal rocking arm 202 to move to adjust the length of the rocking arm assembly 200, and the limiting effect of the guide rod 202b prevents the horizontal rocking arm 202 from rotating. When the length adjustment of the rocking arm assembly 200 is completed, the sliding block 203 is fixed relative to the rocking arm seat 201 by bolts, so that the horizontal rocking arm 202 can be fixed relative to the rocking arm seat 201.

[0049] In addition, it should be noted that in this embodiment, the sliding block 203 is fixed relative to the rocker seat 201 by the cooperation between the bolt and the bolt hole. However, when it is necessary to fine-tune the length of the rocker assembly 200, the mutual cooperation between the bolt and the bolt hole cannot meet the requirement of fine-tuning the length. In this embodiment, the connecting mechanism includes an adjusting member 204, which is rotatably mounted on the sliding block 203, and a threaded rod 205 is mounted on the adjusting member 204. When the adjusting member 204 rotates, it can drive the threaded rod 205 to rotate. In this embodiment, a sleeve 206 is threadedly connected to the threaded rod 205, and the sleeve 206 passes through the slide groove 201a and is connected to the horizontal rocker 202. In this embodiment, the threaded rod 205 is driven to rotate by the rotation of the adjusting member 204, and the sleeve 206 can be driven to move along the length direction of the threaded rod 205. Therefore, the sleeve 206 drives the horizontal rocker 202 to move relative to the rocker seat 201, which is used to fine-tune the length of the rocker assembly 200. In this embodiment, the sliding block 203 is moved and the connecting mechanism drives the horizontal rocker arm 202 to move relative to the rocker arm seat 201 to coarsely adjust the length of the rocker arm assembly 200. After the coarse adjustment is completed, the sliding block 203 is fixed relative to the rocker arm seat 201 by bolts, and then the length of the rocker arm assembly 200 is finely adjusted through the connecting mechanism. Specifically, the adjusting member 204 is rotated to drive the threaded rod 205 to rotate, driving the sleeve 206 to drive the horizontal rocker arm 202 to move, thereby achieving fine adjustment of the length of the rocker arm assembly 200 to adapt to the radius of the guide rail in the vehicle-mounted device.

[0050] The above content is a further detailed description of the present invention in combination with specific implementation methods. It cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, they can make several simple deductions or substitutions without departing from the concept of the present invention, which should be regarded as falling within the scope of protection determined by the claims submitted for the present invention.
