Description

Technical Field

[0001] The invention relates to the technical field of push plate furnaces, in particular to a push plate furnace with a rapid propulsion mechanism. Background Art

[0002] A push plate furnace, also known as a push plate kiln or a push plate tunnel kiln, is a continuous heating and sintering equipment. Its working principle is to heat the air in the furnace through heating elements to form a high-temperature environment. When using a push plate furnace to fire devices, the materials are placed on the push plate, and the push plate is pushed into the furnace by the pushing mechanism on one side of the furnace door. The materials in the furnace are moved between different firing areas through the squeezing and pushing between the push plates, thereby completing the preheating, high-temperature sintering and cooling work in the device firing.

[0003] Chinese patent CN104197703B discloses a double-group push plate ceramic electric kiln, which guides the heat of the discharge port to the adjacent feed port by setting the inlet and outlet directions of the two ceramic electric kilns in opposite directions, thereby improving the heat utilization rate.

[0004] In the prior art, the pushing mechanism of the push plate furnace usually moves the push plates stacked on the track in front of the push rod by a hydraulic push rod, and then controls the push rod to retreat so that a space for inserting at least one push plate appears in front of the push rod, and then another push plate is transported to the front side of the push rod by the side conveying roller, and then the push plate is pushed to move by the hydraulic push rod, and the moving push plate contacts the front push plate and pushes it together. The mechanical pushing mechanism used in the above device uses a similar pushing method, which has a long interval. Each time the push plate is pushed to move a certain distance, it needs to stop for a long time in order to transport the push plate to the front side of the push rod before continuing the pushing operation, resulting in low pushing efficiency.

[0048] 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. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. 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. Embodiment 1

[0049] See also Figure 1 and Fig.10 The present invention provides a push plate furnace with a fast advancing mechanism, comprising a kiln 1, a furnace door 11 is arranged at the feeding end of the kiln 1, a conveying mechanism 2 and a material advancing mechanism 3 are arranged on one side of the furnace door 11, the conveying mechanism 2 comprises a branch feeding track 21, a long straight roller conveyor 22, a short straight roller conveyor 23 and a rotating roller conveyor 24, the branch feeding track 21 is fixedly installed on one side of the furnace door 11, and the output end of the branch feeding track 21 is opposite to the furnace door 11, the long straight roller conveyor 22 and the short straight roller conveyor 23 are respectively fixedly installed at the openings of the two input ends of the branch feeding track 21, the conveying direction of the long straight roller conveyor 22 is perpendicular to the input direction of the adjacent input end of the branch feeding track 21, and the short straight roller conveyor 24 is provided at the same time. The conveying direction of the roller conveyor 23 is perpendicular to the input direction of the input end of the adjacent branch loading track 21. The rotating roller conveyor 24 is arranged between the long straight roller conveyor 22 and the short straight roller conveyor 23, and is used to receive the material output by the long straight roller conveyor 22 and convey the material to the short straight roller conveyor 23; the material pushing mechanism 3 is used to push the materials on the long straight roller conveyor 22 and the short straight roller conveyor 23 from the two input ends of the branch loading track 21 to the output end of the branch loading track 21 respectively. A driving mechanism 4 is arranged between the two material pushing mechanisms 3, and the driving mechanism 4 is used to drive the two material pushing mechanisms 3 to work alternately, so that the two material pushing mechanisms 3 alternately push the material to move to the output end of the branch loading track 21.

[0050] As can be seen from the above, by setting up the branch feeding track 21, the long straight roller machine 22, the short straight roller machine 23 and the rotating roller machine 24, the two material pushing mechanisms 3 can both discharge the material when the other material pushing mechanism 3 pushes the material forward, thereby eliminating the time for the material pushing mechanism 3 to wait for the discharge. By setting up a driving mechanism 4 for driving the two material pushing mechanisms 3 to work alternately, the two material pushing mechanisms 3 can alternately push the material forward, thereby improving the pushing efficiency of the material pushing mechanism 3; specifically, when the material moves from one end of the long straight roller machine 22 to one of the input ends close to the branch feeding track 21, the material on the long straight roller machine 22 can be pushed into the branch feeding track 21 by the material pushing mechanism 3. In addition, when the material is not pushed into the branch feeding track 21, it can be moved to the rotating roller machine 24, and through the rotation of the roller plate of the rotating roller machine 24 and the rotation of the roller on the roller plate, the material is moved to the short straight roller machine 23 and pushed into the other input end of the branch feeding track 21 by another material pushing mechanism 3. Therefore, when using When using the push-plate furnace, the long straight roller conveyor 22 drives the material thereon to move two distances, the front material is directly moved to the rotating roller conveyor 24, and the rear material is moved to the vicinity of the input end of the branch feeding track 21, and then the material pushing mechanism 3 adjacent to the long straight roller conveyor 22 pushes the rear material into the branch feeding track 21. At the same time, the rotating roller conveyor 24 transports the material thereon to the short straight roller conveyor 23. When the material pushing mechanism 3 adjacent to the long straight roller conveyor 22 completes the pushing and retreats to the initial position, the material pushing mechanism 3 adjacent to the short straight roller conveyor 23 can push the material into the branch feeding track 21. At this time, the long straight roller conveyor 22 can drive the material thereon to move two distances, so that the front material is directly moved to the rotating roller conveyor 24, and the rear material is moved to the vicinity of the input end of the branch feeding track 21. Therefore, when the material pushing mechanism 3 of the push-plate furnace continues to work, the time for moving the material to the front of the material pushing mechanism 3 can be reduced, thereby improving the working efficiency of the material pushing mechanism 3. Embodiment 2

[0051] like Figure 1 - Figure 5 As shown, the difference between this embodiment and the above embodiment is that the material pushing mechanism 3 includes a frame 31, a guide rod 32, a slider 33, a sliding rod 34 and a pushing rod 35. The two frames 31 are respectively fixedly mounted on the side of the long linear roller conveyor 22 and the short linear roller conveyor 23 away from the branch feeding track 21, the guide rod 32 is fixedly mounted on the upper surface of the frame 31, the two ends of the slider 33 are slidably connected to the guide rod 32, and the slider 33 is fixedly connected to the sliding rod 34, one end of the pushing rod 35 is rotatably connected to one end of the sliding rod 34, and the other end of the pushing rod 35 is fixedly mounted with a pushing plate 38.

[0052] As can be seen from the above, since the slider 33 is slidably connected to the guide rod 32 fixed on the frame 31, the sliding rod 34 fixedly connected to the slider 33 can slide linearly, so the propulsion rod 35 rotatably connected to one end of the sliding rod 34 can be displaced as the sliding rod 34 moves.

[0053] The material pushing mechanism 3 also includes a guide component 36, which includes a top plate 361, which is fixedly installed above the branch feeding track 21 and the frame 31, and a branch guide slide 362 is opened on the top plate 361. A connecting rod 363 is fixedly installed on the upper end of the pushing rod 35, and a mounting plate 364 is rotatably installed on the upper end of the connecting rod 363. A guide wheel 365 is rotatably installed on the upper surface of the mounting plate 364, and the guide wheel 365 is slidably installed on the inner side of the branch guide slide 362.

[0054] As can be seen from the above, by setting the top plate 361 and the branch guide slide 362, since the guide wheel 365 is slidably installed on the inner side of the branch guide slide 362, the end of the push rod 35 away from the sliding rod 34 can only move along the track of the branch guide slide 362. Therefore, the position and direction of the push plate 38 can be controlled so that the push plate 38 will not hit the branch loading track 21.

[0055] The material advancing mechanism 3 also includes a diverging path prevention component 37, which includes an intermediate shaft 371, a rotating baffle 372, a slide bar 373 and an arcuate slide 376. The intermediate shaft 371 is fixedly mounted on the top plate 361, and the intermediate shaft 371 is arranged on the side of the branch guide slide 362 close to the rotating roller conveyor 24. The middle part of the rotating baffle 372 is fixedly mounted on the intermediate shaft 371, and the slide bar 373 is fixedly mounted on one end of the rotating baffle 372 close to the rotating roller conveyor 24. The arcuate slide 376 is opened on the top plate 361, and the arcuate slide 376 is slidably connected to the slide bar 373.

[0056] As can be seen from the above, by setting the intermediate shaft 371 and the rotating baffle 372, when the rotating baffle 372 rotates to make the slide rod 373 slide to one end of the arc slide 376, the branch of the branch guide slide 362 facing an input end of the branch feeding track 21 is closed, and the side of the guide wheel 365 will contact the rotating baffle 372 when it slides and will not enter the closed branch. In actual work, the push rod 35 moves to drive the guide wheel 365 to move from a branch of the branch guide slide 362. When the side of the guide wheel 365 contacts the rotating baffle 372, the rotating baffle 372 can block the other branch of the branch guide slide 362. Therefore, when the push rod 35 is retracted, the guide wheel 365 will not enter the closed branch.

[0057] Furthermore, the anti-divergence component 37 also includes a fixed shaft 374 and a limit spring 375. The fixed shaft 374 is fixedly installed on the top plate 361, and the fixed shaft 374 is arranged on a straight line connecting the axis of the intermediate shaft 371 and the axis of the rotating roller machine 24. The distance between the sliding rod 373 and the intermediate shaft 371 is greater than the distance between the intermediate shaft 371 and the fixed shaft 374. The two ends of the limit spring 375 are rotatably connected to the sliding rod 373 and the fixed shaft 374 respectively.

[0058] As can be seen from the above, by setting the fixed shaft 374 and the limit spring 375, since the fixed shaft 374 is set on the straight line connecting the axis of the intermediate shaft 371 and the axis of the rotating roller machine 24, and the distance between the slide bar 373 and the intermediate shaft 371 is greater than the distance between the intermediate shaft 371 and the fixed shaft 374, therefore, when the slide bar 373 is at both ends of the arc slide 376, the stretching length of the limit spring 375 is the shortest, and when the slide bar 373 is in the middle of the arc slide 376, the stretching length of the limit spring 375 is the longest, and the pulling force is the largest at this time. Therefore, when the rotating baffle 372 is pushed so that one branch of the branch guide slide 362 is closed, the rotating baffle 372 will not rotate freely because the guide wheel 365 has passed. Embodiment 3

[0059] like Figure 1 and Figure 2 As shown, the difference between this embodiment and the above embodiment is that the included angle between the two input ends of the branch feeding track 21 is the same as the rotation angle of the rotating roller conveyor 24.

[0060] As can be seen from the above, by setting the included angle between the two input ends of the branch feeding track 21 to be the same as the rotation angle of the rotary roller conveyor 24 , the rotary roller conveyor 24 can transport the material output by the long straight roller conveyor 22 to the short straight roller conveyor 23 . Embodiment 4

[0061] like Figure 1 , Figure 6 - Fig. 9As shown, the difference between this embodiment and the above embodiment is that the driving mechanism 4 includes a connecting frame 41, a driving shaft 42, a transmission shaft 43, a driven shaft 44, a threaded rod 45 and a driving motor 46, the connecting frame 41 is fixedly installed between the two frames 31, the driving shaft 42 and the transmission shaft 43 are both rotatably installed on the connecting frame 41, the two transmission shafts 43 are symmetrically arranged on both sides of the driving shaft 42, and the two transmission shafts 43 are both transmission connected to the driving shaft 42, the driven shaft 44 and the threaded rod 45 are both rotatably installed on the frame 31, and the driven shaft 44 and the threaded rod 45 are transmission connected, the driven shaft 44 is transmission connected to the transmission shaft 43, the threaded rod 45 is threadedly connected to the lower end of the slider 33, the driving motor 46 is fixedly installed at the bottom of the connecting frame 41, and the driving end of the driving motor 46 is transmission connected to the driving shaft 42.

[0062] As can be seen from the above, since the driving motor 46 , the driving shaft 42 , the transmission shaft 43 , the driven shaft 44 and the threaded rods 45 are sequentially connected in transmission, the driving motor 46 can control the rotation of the two threaded rods 45 .

[0063] A half-tooth gear 421 is fixedly mounted on the driving shaft 42, and a full-tooth gear 431 is fixedly mounted on the transmission shaft 43. The full-tooth gear 431 is meshedly connected with the tooth surface of the half-tooth gear 421, and a sector block 422 is fixedly mounted on the side of the half-tooth gear 421. A T-shaped block 432 is fixedly mounted on the side of the full-tooth gear 431 away from the tooth surface, and a concave arc groove 433 adapted to the sector block 422 is provided at the end of the T-shaped block 432.

[0064] As can be seen from the above, since the half-toothed gear 421 is meshed and connected with the full-toothed gears 431 on both sides, when the tooth surface of the half-toothed gear 421 faces to which side, it can transmit with the full-toothed gear 431 on the same side. At the same time, due to the arrangement of the sector block 422 and the T-shaped block 432, the sector block 422 away from the tooth surface will fit with the concave arc groove 433 of the T-shaped block 432 on the other side, preventing the full-toothed gear 431 that does not transmit with the half-toothed gear 421 from rotating freely. Therefore, in this embodiment, every time the half-toothed gear 421 rotates half a circle, one of the threaded rods 45 drives the sliding rod 34 to complete the advancement or retreat stroke, and cooperates with the attached Figure 8 It can be described as shown in the figure, when the drive shaft 42 rotates half a circle clockwise, it drives the transmission shaft 43 on the left to rotate, so that the propulsion rod 35 on the left pushes the material forward, and then the drive shaft 42 rotates half a circle counterclockwise, so that the transmission shaft 43 on the left rotates in the opposite direction, and the propulsion rod 35 on the left returns to the initial position, and the half-toothed gear 421 also returns to the adjacent Figure 8Then the drive shaft 42 continues to rotate counterclockwise half a circle, driving the right transmission shaft 43 to rotate, so that the right propulsion rod 35 pushes the material forward, and then the drive shaft 42 rotates clockwise half a circle, so that the right propulsion rod 35 returns to the initial position, and the half-toothed gear 421 also returns to the adjacent Figure 8 The location shown in .

[0065] A transmission wheel 434 is fixedly mounted on the transmission shaft 43, a driven wheel 441 is fixedly mounted on the driven shaft 44, the transmission wheel 434 and the driven wheel 441 are connected via a transmission belt, a transmission gear 442 and a follower gear 451 are fixedly mounted on the driven shaft 44 and the threaded rod 45, respectively, the transmission gear 442 and the follower gear 451 are meshingly connected, a driving gear 461 is fixedly mounted on the driving end of the driving motor 46, a driving gear 423 is fixedly mounted on the driving shaft 42, and the driving gear 461 and the driving gear 423 are meshingly connected.

[0066] As can be seen from the above, since the transmission connection between the drive motor 46, the drive shaft 42, the transmission shaft 43, the driven shaft 44 and the threaded rod 45 is through gears or transmission belts, the transmission ratio can be controlled as needed so that the drive shaft 42 rotates half a circle to enable the sliding rod 34 to move a suitable propulsion distance. Embodiment 5

[0067] like Figure 1 and Fig.10 As shown, the difference between this embodiment and the above embodiment is that a transport roller machine 5 is arranged on the side of the kiln 1, a curved roller machine 6 is arranged between the transport roller machine 5 and the long straight roller machine 22, and the bases of the long straight roller machine 22, the short straight roller machine 23, the rotating roller machine 24, the transport roller machine 5 and the curved roller machine 6 are fixedly connected.

[0068] It can be seen from the above that by providing the curved roller conveyor 6 , the transport roller conveyor 5 can be close to one side of the kiln 1 .

[0069] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
