The crayon transition conveyor realizes transition conveyance of processed and shaped crayons, and performs shape detection on the crayons during the conveying process, and can sort and output crayons that fail the shape detection and crayons that pass the shape detection.

[0027] In this embodiment, there is a blanking gap 9 between the feed end of the crayon unloading mechanism 5 and the discharge port of the guide discharge assembly 7, and the screening mechanism 8 includes a rotating shaft 10, a screening connection plate 11, a swing arm 12 and a swing driver 13. The rotating shaft 10 is rotatably connected to the feed end of the crayon unloading mechanism 5, the screening connection plate 11 is installed on the rotating shaft 10, the screening connection plate 11 is located in the blanking gap 9, and the screening connection plate 11 is used to connect with the discharge port of the guide discharge assembly 7. One end of the swing arm 12 is installed on one end of the rotating shaft 10, and the swing driver 13 is arranged on one side of the crayon unloading mechanism 5. The output end of the swing driver 13 is used to drive the swing arm 12 to swing. Specifically, the swing driver 13 can use a driving cylinder, the cylinder body of the driving cylinder is hinged to one side of the crayon unloading mechanism 5, and the piston rod of the driving cylinder is fixedly connected to the end of the swing arm 12 away from the rotating shaft 10.

[0028] In actual application, when the screening connection plate 11 is disconnected from the guide discharge assembly 7, the crayons that fail the appearance inspection will fall into the material gap 9 onto the bad output mechanism 6, and the bad output mechanism 6 will output the crayons that fail the appearance inspection; when the crayons transported by the lifting and conveying mechanism 3 pass the appearance inspection, the swing driver 13 drives the swing arm 12 to swing forward, the swinging swing arm 12 drives the rotating shaft 10 to rotate forward, and the rotating shaft 10 drives the screening connection plate 11 to swing forward, and the screening connection plate 11 swings forward to connect with the discharge port of the guide discharge assembly 7, and the crayons that pass the appearance inspection output by the guide discharge assembly 7 move to the screening connection plate 11, and move along the screening connection plate 11 to the crayon discharge mechanism 5, and the crayon discharge mechanism 5 outputs the crayons that pass the appearance inspection. On the contrary, the screening connection plate 11 swings in the opposite direction, so that the screening connection plate 11 is disconnected from the guide discharge assembly 7.

[0029] In this embodiment, the crayon unloading mechanism 5 includes a unloading hopper 14, and left and right limit plates 15 are arranged on both sides of the feeding end of the unloading hopper 14. The discharge port of the guide unloading component 7 extends between the two left and right limit plates 15. The screening connecting plate 11 is located between the two left and right limit plates 15. The swing drive 13 and the swing arm 12 are both located on one side of the unloading hopper 14. The interior of the unloading hopper 14 is provided with a unloading inclined plate 16 and a unloading channel 17 connected to the unloading inclined plate 16. The unloading gap 9 is located between the unloading inclined plate 16, the discharge port of the guide unloading component 7 and the two left and right limit plates 15. When the screening connection plate 11 is connected with the discharge port of the guide discharge assembly 7, in the process of the guide discharge assembly 7 outputting the crayons to the screening connection plate 11, the two left and right limit plates 15 limit the two ends of the crayons, thereby improving the position accuracy and stability of the movement of the crayons, which is conducive to the crayons being able to stably move through the screening connection plate 11 to the discharge hopper 14. The crayons in the discharge hopper 14 move along the discharge inclined plate 16 to the discharge channel 17, and the discharge channel 17 outputs the crayons.

[0030] Specifically, a feeding observation slot 42 is provided in the middle of the front side wall of the feeding hopper 14, and the feeding observation slot 42 runs through the middle of the feeding channel 17. When the crayons move along the feeding channel 17, the operator can observe the feeding of the crayons in the feeding channel 17 through the feeding observation slot 42. When the crayons are stuck in the feeding channel 17, the operator can also adjust the crayons in the feeding channel 17 through the feeding observation slot 42 to ensure that the crayons can move normally in the feeding channel 17.

[0031] In this embodiment, the defective output mechanism 6 includes a defective output inclined plate 18 arranged on the outside of the lower hopper 14 and located below the discharge port of the guide discharge assembly 7, and a defective output guide member 19 installed on the frame 1 and connected to the bottom end of the defective output inclined plate 18. The defective output guide member 19 is located below the lifting and conveying mechanism 3.

[0032] In actual application, crayons that fail the appearance inspection fall from the blanking gap 9 onto the bad output inclined plate 18, and the crayons move along the bad output inclined plate 18 to the bad output guide 19, and the bad output guide 19 outputs the crayons in a directional manner.

[0033] In this embodiment, the crayon feeding device 2 includes a feeding hopper 20 installed on the frame 1, a thumbwheel 21 rotatably connected to the feeding hopper 20, and a rotating driver 22 installed on the frame 1 or the outer wall of the feeding hopper 20. The rotating driver 22 is used to drive the thumbwheel 21 to rotate. A feeding ramp 23 and a feeding channel 24 connected to the feeding ramp 23 are provided in the feeding hopper 20. The discharge port of the feeding channel 24 is located above the feeding end of the lifting and conveying mechanism 3. A feeding observation slot 25 is opened in the middle of the feeding hopper 20. The feeding observation slot 25 runs through the feeding channel 24 and the feeding ramp 23. The thumbwheel 21 is located below the feeding ramp 23, and the thumbwheel 21 extends into the feeding observation slot 25.

[0034] In actual application, the processed and formed crayons are transported to the feeding hopper 20, and the rotating driver 22 drives the thumbwheel 21 to rotate. The thumbwheel 21 extends into the feeding hopper 20 through the feeding observation slot 25. The rotating thumbwheel 21 will move the crayons in the feeding hopper 20, so that the crayons in the feeding hopper 20 are loosened, which is conducive to the crayons moving along the feeding inclined plate 23 to the feeding channel 24, and the crayons move along the feeding channel 24 to the lifting and conveying mechanism 3. Among them, the thumbwheel 21 moves the crayons to prevent too many crayons from getting stuck in the feeding hopper 20, which is conducive to the stable and smooth output of the crayons from the feeding channel 24. In addition, the feeding observation slot 25 can not only observe the situation of the crayons in the feeding hopper 20, but also facilitate the operator to adjust the crayons in the feeding hopper 20 through the feeding observation slot 25 to ensure that the crayons can move normally in the feeding channel 24.

[0035] Specifically, the feeding hopper 20 includes two feeding shells 43 symmetrically mounted on the frame 1, and the feeding observation slot 25 is located between the two feeding shells 43. This structural design not only realizes the modular assembly of the feeding hopper 20 and facilitates the molding of the feeding observation slot 25, but also can adjust the distance between the two feeding shells 43 according to different lengths of crayons.

[0036] In this embodiment, the crayon feeding device 2 also includes a toggle wheel 26 rotatably arranged on the top outer side of the feeding channel 24, the toggle wheel 26 extends into the feeding channel 24 through the feeding observation slot 25, and the rotary driver 22 is used to drive the toggle wheel 26 to rotate.

[0037] In actual application, the rotary driver 22 drives the paddle wheel 26 to rotate, and the rotating paddle wheel 26 paddles the crayons in the feeding channel 24 upward, so that the crayons move stably and smoothly in the feeding channel 24 .

[0038] In this embodiment, the crayon feeding device 2 also includes a quick unloading wheel 27 rotatably arranged on the bottom outer side of the feeding channel 24, the quick unloading wheel 27 extends into the feeding channel 24 through the feeding observation slot 25, the quick unloading wheel 27 and the toggle wheel 26 are respectively located on both sides of the feeding channel 24, the quick unloading wheel 27 is located on the side of the feeding channel 24 away from the lifting and conveying mechanism 3, and the rotating driver 22 is used to drive the quick unloading wheel 27 to rotate.

[0039] In actual application, the rotary driver 22 drives the fast unloading wheel 27 to rotate, and the rotating fast unloading wheel 27 pushes the crayons in the feeding channel 24 downward, so that the crayons in the feeding channel 24 quickly fall onto the lifting and conveying mechanism 3.

[0040] In this embodiment, the lifting and conveying mechanism 3 includes a lifting frame 28 obliquely mounted on the frame 1, a lower shaft rod 29 rotatably connected to the lower end of the lifting frame 28, an upper shaft rod 30 rotatably connected to the upper end of the lifting frame 28, two lower transmission wheels 31 coaxially sleeved on the lower shaft rod 29, two upper transmission wheels 32 coaxially sleeved on the upper shaft rod 30, a first transmission bar 33 transmission-connected between one lower transmission wheel 31 and one upper transmission wheel 32, a second transmission bar 34 transmission-connected between another lower transmission wheel 31 and another upper transmission wheel 32, and a plurality of transmission bars 35 along the upper shaft rod 30. A plurality of first lifting hooks 35 are evenly arranged on the first transmission bar 33 along the length direction of the first transmission bar 33, and a plurality of second lifting hooks 36 are evenly arranged on the second transmission bar 34 along the length direction of the second transmission bar 34. The plurality of first lifting hooks 35 are respectively arranged in one-to-one correspondence with the plurality of second lifting hooks 36. The two upper transmission wheels 32 are respectively arranged in one-to-one correspondence with the two lower transmission wheels 31. A broken pen dropping groove 37 is arranged between the first transmission bar 33 and the second transmission bar 34. The rotary driver 22 is used to drive the upper shaft rod 30 or the lower shaft rod 29 to rotate. Specifically, the upper transmission wheel 32 and the lower transmission wheel 31 can both adopt sprocket wheels, the first transmission bar 33 and the second transmission bar 34 can both adopt chains, and the first lifting hook 35 and the second lifting hook 36 are both √-shaped.

[0041] In actual application, the feeding channel 24 outputs the crayons to the corresponding first lifting hook 35 and second lifting hook 36. Broken crayons or crayons of insufficient length will fall out of the lifting and conveying mechanism 3 from the broken crayon drop trough 37 to exclude the broken crayons or crayons of insufficient length. The first lifting hook 35 and second lifting hook 36 at the corresponding position support both ends of the normal crayons. At the same time, the rotary driver 22 drives the upper shaft 30 or the lower shaft 29 to rotate, so that the upper transmission wheel 32 on the upper shaft 30 or the lower transmission wheel 31 on the lower shaft 29 rotates, and then the first transmission bar 33 and the second transmission bar 34 rotate synchronously, so that the first lifting hook 35 and the second lifting hook 36 cooperate to convey the crayons upward. When the crayons are conveyed to the guide discharging assembly 7, the crayons are discharged along the guide discharging assembly 7. This structural design can not only realize the conveying of crayons, but also exclude broken crayons and crayons of insufficient length to realize the preliminary screening of crayons, thereby improving the quality of crayons.

[0042] In this embodiment, the guide discharge assembly 7 includes an arc plate 38 installed at the top of the lifting frame 28 and located on the outside of the first lifting hook 35 and the second lifting hook 36, and a guide inclined plate 39 arranged on the lower side of the top of the lifting frame 28 and inclined downward. The bottom end of the guide inclined plate 39 is located above the defective output mechanism 6, and the top end of the guide inclined plate 39 is connected to the crayons output by the first lifting hook 35 and the second lifting hook 36. The bottom end of the guide inclined plate 39 can be connected to the screening mechanism 8, and the arc plate 38 is located at the top corner of the first transmission bar 33 and the second transmission bar 34. In actual application, the arc plate 38 limits and guides the crayons on the first lifting hook 35 and the second lifting hook 36, so that the crayons can stably move to the guide inclined plate 39. When the screening connecting plate 11 is connected with the guide inclined plate 39, the crayons move along the guide inclined plate 39 to the screening connecting plate 11, and then move along the screening connecting plate 11 to the lower hopper 14; when the screening connecting plate 11 is disconnected from the guide inclined plate 39, the crayons move along the guide inclined plate 39 and fall onto the defective output mechanism 6 through the blanking gap 9.

[0043] In addition, a rotary driver 22 drives the dial wheel 21, the dial wheel 26, the fast unloading wheel 27 and the upper shaft 30 or the lower shaft 29 of the lifting and conveying mechanism 3 to rotate at the same time, which reduces the number of driving sources, has a compact structure, saves resources, and reduces the cost of production. Specifically, the rotary driver 22 can adopt a transmission structure such as a motor, a synchronous belt and a synchronous wheel.

[0044] The present invention also provides a crayon production line, including a crayon forming machine 40, a crayon paper winding machine 41 and the above-mentioned crayon transition conveyor, the discharge end of the crayon forming machine 40 is connected to the feed port of the crayon feeding device 2 of the crayon transition conveyor, and the feed end of the crayon paper winding machine 41 is connected to the discharge port of the crayon discharge mechanism 5 of the crayon transition conveyor.

[0045] In actual application, the crayon molding machine 40 processes and molds crayons and conveys the crayons to the crayon feeding device 2 of the crayon transition conveyor. The lifting and conveying mechanism 3 of the crayon transition conveyor conveys the crayons supplied by the crayon feeding device 2 to the guide discharge component 7, and then the crayons after the appearance inspection are screened and output through the screening mechanism 8, so that the crayons that pass the appearance inspection are conveyed to the crayon unloading mechanism 5, and the crayons that fail the appearance inspection fall to the defective output mechanism 6. The crayon unloading mechanism 5 conveys the crayons to the crayon paper winding machine 41, and the crayon paper winding machine 41 labels the crayons.

[0046] Specifically, the crayon shape detection device 4 can adopt a shape detection mechanism in the prior art, which will not be described in detail here.

[0047] All technical features in this embodiment can be freely combined according to actual needs.

[0048] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention may also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
