[0001] Technology

[0002] The invention relates to the technical field of resin manhole cover processing devices, and in particular to an automatic resin manhole cover burr removal device based on a turntable. Background Art

[0003] Resin manhole covers are made of glass fiber and resin as basic materials, with curing agent, accelerator and other auxiliary materials. They are insulating and noiseless. Unlike cast iron manhole covers, resin manhole covers are formed by hydraulic pressing and grinding. Burrs will appear around them after forming. Currently, most of them are removed manually, which has high labor and time costs.

[0004] A Chinese invention patent with application publication number CN114536619A discloses a resin manhole cover processing device, including a workbench, a No. 1 motor, a conveyor, a fixed push rod, a support column, a first support frame, a second support frame, a fixed frame, a burr scraping mechanism, a cooling device, etc. The present invention automatically removes burrs around the resin manhole cover formed by high-temperature grinding and pressing, ensuring that the resin manhole cover is not damaged when removing the burrs; the handle installation mechanism can simultaneously install two metal handles in the resin manhole cover, thereby increasing the installation speed of the handle. A Chinese invention patent with application publication number CN114290167A discloses a manhole cover processing equipment for municipal facility production, including a manhole cover ear processing unit and a fixing unit, etc.; the right part of the manhole cover ear processing unit is connected to the fixing unit. The present invention removes burrs by rotating the manhole cover ear slot after fixing the single-ear manhole cover, and adaptively grinding the side of the opening hole to remove burrs, thereby avoiding the burrs on the manhole cover from affecting the assembly of the manhole cover, and effectively improving work efficiency.

[0005] However, the inventors found that the device has the following problems: the manhole covers can only be deburred one by one, with poor continuity and low efficiency, and there is a lack of mechanism for removing the burrs inside the water holes of the manhole covers.

[0032] The technical solutions in the embodiments of the present invention are clearly and completely described below in conjunction with the accompanying drawings.

[0033] Embodiment 1

[0034] like Figures 1 to 8As shown, an automated resin manhole cover burr removal device based on a turntable type includes a motor a1 and a turntable 2 driven by the motor a1, a centering component 3, a limiting component 4, a removing component 5, and a through-hole component 6. The turntable 2 is provided with a plurality of turntables 7 that rotate along its circumferential direction. The turntable 7 is used for placing the manhole cover. The limiting component 4 and the removing component 5 are arranged above the turntable 7. The centering component 3 is used to make the manhole cover and the turntable 7 coaxial. The limiting component 4 is used to slide downward and cooperate with the turntable 7 to limit the resin manhole cover during the rotation of the turntable 2. The removing component 5 is used to self-rotate and remove the burrs of the resin manhole cover during the rotation of the turntable 2. The limiting component 4 is also used to drive the resin manhole cover to rotate during the rotation of the turntable 2 and cooperate with the through-hole component 6 to remove the burrs in the water holes of the resin manhole cover.

[0035] like Figure 4 As shown, a rotating frame 31 is arranged on the turntable 2, and the limiting assembly 4 includes a slide rod 32 slidably arranged on the rotating frame 31, a limiting plate 33 is arranged on the lower end surface of the slide rod 32, and a guide rail a34 is arranged above the turntable 2 to drive the slide rod 32 to rise and fall.

[0036] It is worth mentioning here that by setting a guide rail a34 above the turntable 2 to drive the slide rod 32 to rise and fall, the slide rod 32 can drive the limit plate 33 to descend under the action of the guide rail a34, so that the manhole cover is fixed on the turntable 7 to prevent the manhole cover from shifting during the deburring process.

[0037] like Figure 3 As shown in FIG. 4 , the centering assembly 3 includes a centering rod 21 slidably arranged on both sides of the turntable 7. The centering rod 21 is fixed on the sliding rod 32 through a connecting rod. The centering rod 21 is symmetrically arranged on both sides of the central axis of the turntable 7.

[0038] It is worth mentioning that by symmetrically arranging the centering rods 21 on both sides of the central axis of the turntable 7, it can be ensured that the manhole cover in contact with the centering rods 21 on both sides maintains the same axis as the turntable 7.

[0039] like Figure 3 ,4, the removal component 5 includes a ring 41 rotatably set on the sliding rod 32, a support rod 42 is set on the ring 41, a scraper 43 is set on the lower end surface of the support rod 42, a gear ring a44 is set on the outer end surface of the ring 41, and an arc-shaped rack a45 meshing with the gear ring a44 is set above the turntable 2.

[0040] It is worth mentioning here that by arranging a scraper 43 on the lower end face of the support rod 42 and a gear ring a44 on the outer end face of the ring 41, the gear ring a44 is driven to rotate by an arc-shaped rack a45 arranged above the turntable 2, thereby driving the scraper 43 to rotate and removing the burrs around the manhole cover.

[0041] like Figure 5 As shown in FIG8 , the through-hole assembly 6 includes through-hole rods 51 slidably arranged on both sides of the turntable 7, and the through-hole rods 51 are connected by connecting rods 52. A linkage rod 53 is slidably arranged on the connecting rod 52, and a linkage protrusion 54 is arranged on the lower end surface of the linkage rod 53. A guide rail b55 for driving the linkage protrusion 54 to rise and fall is arranged under the turntable 2.

[0042] It is worth mentioning here that a guide rail b55 is set under the turntable 2 to drive the linkage protrusion 54 to rise and fall, so that the linkage protrusion 54 drives the through-hole rod 51 to rise through the linkage rod 53 under the action of the guide rail b55, thereby removing the burrs in the water through hole of the manhole cover.

[0043] like Figure 2 As shown in FIG. 4 , a gear ring b61 is arranged on the slide rod 32, and the gear ring b61 is arranged above the sleeve ring 41. An arc-shaped rack b62 meshing with the gear ring b61 is arranged on the turntable 2.

[0044] It is worth mentioning here that by arranging a gear ring b61 on the sliding rod 32 and arranging an arc-shaped rack b62 meshing with the gear ring b61 on the turntable 2, the gear ring b61 can be driven by the arc-shaped rack b62 to rotate, thereby driving the manhole cover on the turntable 7 to rotate, so that when the water hole on the manhole cover coincides with the through-hole rod, the burrs in the water hole can be removed.

[0045] like Figure 7 As shown, a limit ring 71 is provided on the upper end surface of the slide rod 32 , and a spring a72 sleeved on the slide rod 32 is provided between the limit ring 71 and the rotating frame 31 .

[0046] It is worth mentioning here that, by providing a spring a72 sleeved on the slide bar 32 between the limit ring 71 and the rotating frame 31 , the limit ring 71 can be driven to move by the spring a72 , thereby driving the slide bar 31 to reset.

[0047] like Figure 8 As shown, a spring b81 sleeved on the linkage rod 53 is provided between the linkage protrusion 54 and the connecting rod 52 .

[0048] It is worth mentioning here that by providing a spring b81 sleeved on the linkage rod 53 between the linkage protrusion 54 and the connecting rod 52, the linkage protrusion 54 can rise under the action of the guide rail b55, thereby driving the through-hole rod 51 to rise. The through-hole rod 51 stops after it abuts against the lower end surface of the manhole cover. At this time, the linkage rod 53 continues to rise to compress the spring b81, so that the through-hole rod 51 shows a tendency to prepare a through hole. When the limiting plate 33 drives the manhole cover to rotate and the water hole coincides with the through-hole rod 51, the effect of removing the burrs inside the water hole is achieved.

[0049] like Figure 3 As shown, the arc-shaped rack b64 and the arc-shaped rack a45 are both fixedly arranged on the outer end surface of the turntable 2, and the arc-shaped rack b62 and the arc-shaped rack a45 are both coaxial with the turntable 2.

[0050] like Figure 6 As shown, a baffle 91 is provided on the scraper 43 .

[0051] It is worth mentioning that, by providing a baffle 91 on the scraper 43, it is possible to prevent the scraper 43 from scraping too much during the process of removing burrs, thereby affecting the size of the manhole cover.

[0052] The working process is as follows:

[0053] The worker puts the manhole cover on the turntable 7, and fits the manhole cover with the centering rods 21 on both sides, and starts the motor a1, which drives the turntable 2 to rotate. During the rotation of the turntable 2, the slide bar 32 is driven by the guide rail a34 to drop, and the slide bar 32 drives the limit plate 33 to drop. The limit plate 33 fixes the manhole cover on the turntable 7. When the turntable 2 drives the manhole cover to rotate to the arc-shaped rack a45, the arc-shaped rack a45 drives the ring 41 to rotate through the gear ring a44, and the ring 41 drives the scraper 43 on the lower end surface to rotate along the circumference of the manhole cover through the support rod 42, thereby removing the burrs around the manhole cover;

[0054] After the burrs around the manhole cover are removed, the turntable 2 drives the manhole cover to continue to rotate, and the linkage protrusion 54 drives the linkage rod 53 to rise under the action of the guide rail b55. The linkage rod 53 drives the connecting rod 52 to rise through the spring b81, and the connecting rod 52 drives the through-hole rod 51 to rise. When the through-hole rod 51 abuts against the lower end surface of the manhole cover, the through-hole rod 51 stops. At this time, the linkage rod 53 continues to rise to compress the spring b81, so that the through-hole rod 51 is in a pre-through-hole state;

[0055] When the turntable 2 drives the manhole cover to rotate to the arc-shaped rack b62, the arc-shaped rack b62 cooperates with the gear ring b61 to drive the slide bar 32 to rotate. The limit plate 33 is now in a state of pressing the manhole cover turntable, and the limit plate 33 drives the manhole cover to rotate with the turntable 7. During the rotation of the manhole cover, when the water hole and the through-hole rod 51 coincide with each other, the gear ring b61 is in an idling state, and the through-hole rod 51 rises under the action of the spring b81 to remove the burrs in the water hole.

[0056] After removing the burrs of the water hole, the through-hole rod 51 is reset under the action of the guide rail b55 and the spring b81, and the limit plate 33 is reset under the action of the guide rail a34 and the spring a72. At this time, the worker removes the completed manhole cover for subsequent processing.
