[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] For example, see Figure 1-7 The present invention provides a plug pressing device for fluorescent tube production, comprising a base 1, a support plate 2 is fixedly connected to the top of the base 1, a feeding box 3 is slidably connected to the top of the support plate 2, and a storage box 8 is fixedly connected to the side wall of the base 1;

[0032] The side wall of the feeding box 3 is provided with a feeding mechanism 4. Further, the feeding mechanism 4 includes a fixed frame 403 and a movable plate 404, and the inner wall of the fixed frame 403 is slidably connected with an L-shaped block 402, the side wall of the L-shaped block 402 is fixedly connected with a first spring 401, and the end of the first spring 401 away from the L-shaped block 402 is fixedly connected to the inner wall of the fixed frame 403, the outer wall of the movable plate 404 is fixedly connected with a stopper 407, and the position of the movable plate 404 corresponding to the inner wall of the stopper 407 is fixedly connected with a first tension spring 4 06, one end of the moving plate 404 is slidably connected to a connecting rod 405, and the outer wall of the connecting rod 405 is slidably connected to a slider 408, a side wall of the slider 408 is provided with a tooth groove 409, an end of a first tension spring 406 away from the moving plate 404 is fixedly connected to the side wall of the slider 408, and the inclined surface of the slider 408 corresponds to the circular side wall of the sliding plate 5, the side wall of the moving plate 404 is fixedly connected to a second tension spring 410, and the end of the second tension spring 410 away from the moving plate 404 is fixedly connected to the side wall of the charging box 3;

[0033] More specifically, in this embodiment, the feeding box 3 can be opened by the handle on the top of the feeding box 3, and then the pre-processed raw materials are added into the feeding box 3, and then the pressing work can be carried out;

[0034] Then, the electric push rod 11 is driven to drive the push plate 12 fixedly connected to the output shaft to move, and then the push plate 12 will drive the moving rods 13 at both ends to move synchronously. At this time, the moving rod 13 will drive the L-shaped block 402 to move, so that the L-shaped block 402 will squeeze the first spring 401. Since the hardness of the first spring 401 is relatively high, it will drive the feeding box 3 to slide on the top of the support plate 2 through the fixed frame 403 when it is not compressed. Then, after the feeding box 3 slides to a certain position, the moving rod 13 will contact the limiting mechanism 9. The limiting mechanism 9 includes a sliding cylinder 9 01, and the inner wall of the sliding cylinder 901 is slidably connected to the limit block 903, and the bottom of the limit block 903 is fixedly connected with a second spring 902, and the end of the second spring 902 away from the limit block 903 is fixedly connected to the bottom of the sliding cylinder 901, and the side wall of the limit block 903 is penetrated with an oblique groove 904, and the end away from the push plate 12 by the moving rod 13 will slide on the inclined surface of the oblique groove 904, and then the limit block 903 will slide toward the bottom of the sliding cylinder 901. When the moving rod 13 penetrates the oblique groove 904, the sliding cylinder 9 The side wall of 01 will be engaged in the card slot 14, so as to limit the feeding box 3. At the same time, the plurality of feeding ports 15 correspond to the plurality of mold holes 19 below. Then, the electric push rod 11 outputs to make the L-shaped block 402 compress the first spring 401. At the same time, the inclined surface of the L-shaped block 402 squeezes the inclined surface of the moving plate 404. In this way, the moving plate 404 will slide outward. After sliding, the moving plate 404 will no longer block the top of the feeding port 15, so that the inside of the feeding port 15 and the inside of the mold hole 19 are connected, and the inside of the feeding box 3 is The raw material falls into the mold hole 19 through the feeding port 15. Then, when the filling is completed and reset is performed, the electric push rod 11 is retracted to reset the L-shaped block 402. At this time, the moving plate 404 is contracted by the second tension spring 410 to slide toward the inner wall of the feeding box 3 to the top of the feeding port 15. After the reset is completed, the feeding port 15 can be closed. Then the moving rod 13 is disengaged from the inside of the oblique through groove 904. At this time, the limit block 903 is affected by the rebound force of the second spring 902, thereby sliding upward and disengaging from the groove 14. Then the electric push rod 11 drives the feeding box 3 to reset.

[0035] By doing as above, the electric push rod 11 pushes the feeding box 3 to move. After the feeding box 3 moves to the specified position, the electric push rod 11 will continue to drive the L-shaped block 402 to move, so that the movable plate 404 can be squeezed and moved outward, thereby connecting the interior of the feeding port 15 and the interior of the feeding box 3, so that the raw materials inside the feeding box 3 fall into the interior of the mold hole 19 through the feeding port 15, so that the feeding box 3 can automatically load materials after sliding to the specified position, thereby improving work efficiency.

[0036] Embodiment 2, based on the above embodiment, a sliding plate 5 is slidably connected to the top of the base 1, so that the pressed plug can be pushed out during the feeding process, and a slot 6 is provided inside the sliding plate 5, and a discharge mechanism 7 is provided on the inner wall of the slot 6;

[0037] Further, the unloading mechanism 7 includes a first ring 701, and the outer wall of the first ring 701 is rotatably connected to the first chain 702, the inner wall of the first chain 702 is rotatably connected to the second ring 703, and the outer wall of the second ring 703 is rotatably connected to the second chain 704, the inner wall of the second chain 704 is rotatably connected to another second ring 703, and the top of the second ring 703 is fixedly connected to the unloading mold 16, the outer wall of the first chain 702 corresponds to the inner wall of the tooth groove 409, the top of the sliding plate 5 is fixedly connected to the third spring 17, and the end of the third spring 17 away from the sliding plate 5 is fixedly connected to the lower mold 18, a plurality of mold holes 19 are opened inside the lower mold 18, and the inner wall of the mold hole 19 corresponds to the outer wall of the unloading mold 16, and the side wall of the lower mold 18 is fixedly connected to the side wall of the support plate 2;

[0038] More specifically, in the present embodiment, during the process of loading the device, the inclined surface of the slider 408 contacts the circular side wall of the sliding plate 5, so while the feeding box 3 slides, the sliding plate 5 can be moved by the inclined surface of the slider 408. At this time, the slider 408 will slide to the bottom of the sliding plate 5 to support the sliding plate 5, and at the same time, the third spring 17 will be compressed, and then the sliding plate 5 will drive the unloading mold 16 to lift upward, so that the outer wall of the unloading mold 16 slides upward along the inner wall of the mold hole 19. During this process, the distance between the sliding plate 5 and the lower mold 18 gradually becomes smaller, and the plug that was pressed last time can be pushed out by the sliding of the unloading mold 16. When the inclined surface of the slider 408 completely slides to the bottom of the sliding plate 5, the top of the unloading mold 16 will be level with the top of the lower mold 18, and the plug that was pressed last time will be pushed out to the top of the lower mold 18, and then the unloading mold 16 will be pushed out to the top of the lower mold 18, and then the unloading mold 16 will be pushed out to the top of the lower mold 18. When the L-shaped block 402 slides to the top of the lower mold 18, the side wall of the feeding box 3 will push the plug to the edge of the lower mold 18, and then it will fall into the storage box 8. In the process of the L-shaped block 402 pressing the movable plate 404, the end of the movable plate 404 will slide along the connecting rod 405, and the movable plate 404 will press the slider 408 through the stopper 407, so that it will also slide on the outer wall of the connecting rod 405. After the sliding of the movable plate 404 is completed, the inclined surface of the slider 408 will slide from the bottom of the sliding plate 5 to the side of the sliding plate 5. After the slider 408 is completely separated from the bottom of the sliding plate 5, the force generated by the compression of the third spring 17 will be released, so that the sliding plate 5 will slide downward quickly to complete the reset. At the same time, the unloading mold 16 will slide downward with the sliding plate 5, so that the unloading mold 16 will slide from the inside of the mold hole 19 to the bottom of the mold hole 19, so as to achieve automatic unloading during the loading process.

[0039] After the loading is completed, when the moving plate 404 is reset, it will drive the stopper 407 to slide on the outer wall of the connecting rod 405. At this time, the first tension spring 406 will exert a stretching force on the slider 408. Since the slider 408 on the side of the sliding plate 5 will be limited by the sliding plate 5, it will fit tightly against the side wall of the sliding plate 5. Then, when the feeding box 3 is reset, it will drive the connecting rod 405 to move synchronously, and then the slider 408 will follow the connecting rod 405 to slide along the side wall of the sliding plate 5. During the sliding process of the slider 408, the inner wall of the tooth groove 409 will mesh with the chain teeth of the first chain 702, so that the sliding of the tooth groove 409 will drive the first chain 702 to rotate, and then The second ring 703 that is in contact with its inner wall is driven to rotate, and then the second ring 703 drives another second ring 703 to rotate through the second chain 704. At the same time, the second ring 703 will drive the upper unloading mold 16 to rotate. The rotation of the unloading mold 16 will drive the raw materials that have been loaded inside the mold hole 19 to move, so that they are more evenly dispersed inside the mold hole 19. After that, after the feeding box 3 is reset, the slider 408 will slide back to the circular side wall of the sliding plate 5 through the retraction of the first tension spring 406, and then the upper mold 23 is pressed down by driving the hydraulic cylinder 22, so that the pressing module at the bottom of the upper mold 23 can press the raw material inside the mold hole 19.

[0040] As described above, the electric push rod 11 pushes the feeding box 3 to move, so that the inclined surface of the slider 408 squeezes the bottom of the sliding plate 5, thereby lifting the sliding plate 5, which can enable the unloading mold 16 to slide upward along the inner wall of the mold hole 19. During the sliding process, the unloading mold 16 will push out the plug that was pressed last time, and then the feeding box 3 will slide to push the pressed plug into the storage box 8, thereby achieving the effect of automatic unloading. After that, the slider 408 is reset, so that the tooth groove 409 drives the first chain 702 to rotate, and then drives the second ring 703 that is fitted with its inner wall to rotate, and then the second ring 703 drives another second ring 703 to rotate through the second chain 704, and the upper unloading mold 16 drives the raw material to rotate inside the mold hole 19, so that the raw material is dispersed more evenly inside the mold hole 19, effectively improving the subsequent pressing effect.

[0041] Working principle: First, the feeding box 3 can be opened through the handle on the top of the feeding box 3, and then the pre-processed raw materials are added into the feeding box 3, and then the pressing work can be carried out;

[0042] Then, driving the electric push rod 11 can drive the push plate 12 fixedly connected to the output shaft to move, and then the push plate 12 will drive the moving rods 13 at both ends to move synchronously. At this time, the moving rod 13 will drive the L-shaped block 402 to move, so that the L-shaped block 402 will squeeze the first spring 401. Due to the high hardness of the first spring 401, when it is not compressed, it will drive the feeding box 3 to slide on the top of the support plate 2 through the fixed frame 403. Then, after the feeding box 3 slides to a certain position, the moving rod 13 will contact the limiting mechanism 9, and the end of the moving rod 13 away from the push plate 12 will slide on the inclined surface of the oblique through groove 904, and then the limiting block 903 will slide to the bottom of the sliding cylinder 901. When the groove 904 is formed, the side wall of the sliding cylinder 901 will be engaged in the groove 14, so as to limit the feeding box 3. At the same time, the plurality of feeding ports 15 correspond to the plurality of mold holes 19 below. Then, the electric push rod 11 outputs to make the L-shaped block 402 compress the first spring 401. At the same time, the inclined surface of the L-shaped block 402 squeezes the inclined surface of the moving plate 404. In this way, the moving plate 404 will slide outward. After sliding, the moving plate 404 will no longer block the top of the feeding port 15, so that the inside of the feeding port 15 and the inside of the mold hole 19 are connected, and the raw materials in the feeding box 3 fall into the mold hole 19 through the feeding port 15. Then, when the filler is reset after completion, the electric push rod 11 is retracted to make the L-shaped The block 402 is reset, and the moving plate 404 is contracted by the second tension spring 410 to slide toward the inner wall of the feeding box 3 to the top of the feeding port 15. After the reset is completed, the feeding port 15 can be closed, and then the moving rod 13 disengages from the inside of the oblique through groove 904. At this time, the limit block 903 is rebounded by the second spring 902, so that it slides upward and disengages from the slot 14, and then the electric push rod 11 drives the feeding box 3 to reset, and the feeding box 3 is pushed to move by the electric push rod 11, so that the inclined surface of the slider 408 is squeezed against the bottom of the sliding plate 5, thereby lifting the sliding plate 5, which can make the unloading mold 16 slide upward along the inner wall of the mold hole 19. During the sliding process, the unloading mold 16 will push the plug that was pressed last time. After the material is discharged, the feeding box 3 slides to push the pressed plug into the storage box 8, thereby achieving the effect of automatic unloading. After that, the slider 408 is reset to make the tooth groove 409 drive the first chain 702 to rotate, and then drive the second ring 703 that is fitted with its inner wall to rotate. After that, the second ring 703 drives another second ring 703 to rotate through the second chain 704, and the upper unloading mold 16 drives the raw material to rotate inside the mold hole 19, so that the raw material is dispersed more evenly inside the mold hole 19. After that, after the feeding box 3 is reset, the slider 408 will slide back to the circular side wall of the sliding plate 5 through the retraction of the first tension spring 406, and then the upper mold 23 is pressed down by driving the hydraulic cylinder 22.The pressing module at the bottom of the upper mold 23 can press the raw material inside the mold hole 19.
