Description

Technical Field

[0001] This utility model relates to the field of crayon technology, specifically to an automatic crayon tray arrangement mechanism. Background Technology

[0002] Crayons are pencils made by mixing pigments with wax. They come in dozens of colors and are used for drawing. The production of crayons involves multiple processes. First, various pigments are mixed and heated until melted. Then, the melted liquid is sprayed into the matching crayon mold, which is then slowly submerged and filled. Finally, it is cooled, and after a few minutes, it solidifies. After being formed, the crayons undergo inspection, sorting, and packaging. Some crayons need to be placed on trays before packaging to effectively protect them, which is called the tray arrangement step.

[0003] However, most current crayon plating methods rely on manual labor, requiring operators to manually pick up each crayon and place it one by one into the corresponding groove on the plate. This is cumbersome, inconvenient, and labor-intensive, greatly reducing its practicality. To address this issue, we provide an automatic crayon plating mechanism. Utility Model Content

[0004] The purpose of this invention is to provide an automatic crayon tray arrangement mechanism, which solves the problem that most existing tray arrangement methods are done manually, requiring operators to manually pick up each crayon one by one and place them into the corresponding grooves on the tray. This is cumbersome and time-consuming, resulting in low work efficiency and high manpower consumption, which greatly reduces practicality.

[0005] This utility model provides the following technical solution: an automatic crayon tray placement mechanism, comprising several sets of support columns, with a worktable installed at the top of each set of support columns, and a placement mechanism for automatically placing crayons provided from the bottom to the top of the worktable. The placement mechanism includes a reciprocating component and a driving component. A placement frame is provided at the top of the reciprocating component, and a pick-up and put-out opening is provided on the lower side of one end of the placement frame. A placement tray is placed inside the placement frame, and placement slots are provided at equal intervals at the top of the placement tray. Pushing components for pushing crayons are provided on both sides of the placement frame.

[0006] The above technical solution allows for the placement of crayons by placing the placement tray inside the placement frame, making it convenient to replace the placement tray after placement.

[0007] As a preferred embodiment of the above technical solution, the reciprocating assembly includes a support frame and two sets of sector gears. The support frame is installed on the top of the worktable, and a rack is slidably installed on the lower inner side of the support frame. Both sets of sector gears are rotatably installed on both sides of the top of the worktable near the rack via a drive assembly. The rack meshes with the sector gears, and a connecting rod is connected to the top of the rack. A movable groove is opened at the top of the support frame, and the connecting rod slides in the movable groove. The bottom end of the placement frame is fixedly connected to the top of the rack.

[0008] The above technical solution allows several sets of crayons to roll within the placement frame. When a crayon rolls to the corresponding placement slot, it falls into the slot, thus achieving automatic placement without the need for manual placement of each crayon individually. This makes the device simpler, more convenient, and greatly increases its usability.

[0009] As a preferred embodiment of the above technical solution, the drive assembly includes a mounting slot and a motor. The mounting slot is located inside the workbench, and a main gear is rotatably mounted inside the mounting slot. Secondary gears mesh on both sides of the main gear. The top of each set of secondary gears is connected to a sector gear via a connecting shaft. The motor is mounted at the bottom of the workbench, and the output end of the motor extends into the mounting slot and connects to the main gear.

[0010] The above technical solution enables two sets of sector gears to rotate in the same direction, allowing the two sets of sector gears to alternately mesh with the rack and pinion, thus achieving back-and-forth movement.

[0011] As a preferred embodiment of the above technical solution, each set of pushing components includes a support plate, each set of support plates is installed on the side of the placement frame, each set of support plates is equipped with an electric push rod at the end away from the placement frame, the output end of each set of electric push rods is installed with a movable plate through the support plate, and each set of movable plates is provided in a groove at the side of the placement frame.

[0012] The above technical solution allows the crayon to be pushed into a slot that does not contain crayons, causing the crayon to fall into the slot, thus greatly increasing the practicality of the device.

[0013] As a preferred embodiment of the above technical solution, a limiting component for blocking the placement tray is provided on the side of the placement frame near the pick-up and put-out port. The limiting component includes a sliding groove and a slot. The sliding groove and the slot are respectively opened at the top and bottom of the inner wall of the pick-up and put-out port. A baffle is slidably installed inside the sliding groove, and the bottom end of the baffle is inserted into the slot.

[0014] The above technical solution allows for the placement of the tray within the placement frame, preventing the tray from falling out and affecting the plating.

[0015] As a preferred embodiment of the above technical solution, a lever is connected to the upper side of one end of the baffle, and a guide opening is provided on the inner wall of the slide groove near the lever, and the lever slides within the guide opening.

[0016] The above technical solution allows the pick-and-place port to be opened, and the placement tray to be placed into the placement frame from the pick-and-place port.

[0017] As a preferred embodiment of the above technical solution, collision components are provided on both sides of the support frame. Each set of collision components includes a collision block. Each set of collision blocks is slidably installed inside one side of the movable groove. A movable rod is connected to the end of each set of collision blocks away from the connecting rod. A limit plate is connected to the end of each set of movable rods away from the collision block through the support frame. A spring is sleeved on the side of each set of movable rods near the collision block.

[0018] The above technical solution allows the connecting rod to slide within the movable groove. When it collides with the collision block, the connecting rod causes the placement frame and placement tray to vibrate slightly, allowing the crayons to fall into the placement groove more effectively. The spring can then reset the collision block for future use.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] This invention, by setting up a reciprocating component and a driving component, enables several sets of crayons to roll within the placement frame. When a crayon rolls to the corresponding placement slot, it falls into the slot, thus achieving automatic placement without the need for manual placement of each crayon individually, making it simpler and more convenient. Furthermore, by setting up a pushing component, individual crayons that have not fallen into the placement slot can be pushed to an empty slot, causing them to fall into the slot, greatly increasing the practicality of the device.

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0027] like Figure 1 , Figure 2 and Figure 4 As shown, this utility model provides a technical solution: an automatic crayon tray placement mechanism, including several sets of support columns 1, with a worktable 11 installed at the top of each set of support columns 1. A placement mechanism 2 for automatically placing crayons is provided from the bottom to the top of the worktable 11. The placement mechanism 2 includes a reciprocating component 3 and a driving component 4. A placement frame 5 is provided at the top of the reciprocating component 3. A pick-up and drop-off port 51 is opened on the lower side of one end of the placement frame 5. A placement tray 6 is placed inside the placement frame 5. Placement slots 61 are equidistantly opened at the top of the placement tray 6. A limiting component 8 for blocking the placement tray 6 is provided on the side of the placement frame 5 near the pick-up and drop-off port 51. The limiting component 8 includes a sliding groove 81 and a slot 82, which are respectively opened at the top and bottom of the inner wall of the pick-up and drop-off port 51. A baffle 83 is slidably installed inside the groove 81, and the bottom end of the baffle 83 is inserted into the slot 82. This structure allows the baffle 83 to be inserted into the slot 82 after the placement tray 6 is placed in the placement frame 5. This limits the placement tray 6 in the placement frame 5 and prevents it from falling out of the placement frame 5, which would affect the tray placement. A lever 84 is connected to the upper side of one end of the baffle 83. A guide opening 85 is opened on the inner wall of the groove 81 near the lever 84. The lever 84 slides in the guide opening 85. When the lever 84 is pushed upward, it slides in the guide opening 85. The lever 84 drives the baffle 83 to be pulled out of the slot 82 and moved into the groove 81. This opens the pick-up and put-out port 51, and the placement tray 6 is placed into the interior of the placement frame 5 from the pick-up and put-out port 51.

[0028] As one implementation method in this embodiment, such as Figure 2 and Figure 3As shown, the reciprocating assembly 3 includes a support frame 31 and two sets of sector gears 33. The support frame 31 is mounted on the top of the worktable 11. A rack 32 is slidably mounted on the lower side of the inside of the support frame 31. Both sets of sector gears 33 are rotatably mounted on both sides of the top of the worktable 11 near the rack 32 via the drive assembly 4. The rack 32 meshes with the sector gears 33. A connecting rod 34 is connected to the top of the rack 32. A movable groove 35 is opened at the top of the support frame 31, and the connecting rod 34 slides in the movable groove 35. The bottom end of the placement frame 5 is connected to the rack 33. The top end of rack 32 is fixedly connected. This structure allows two sets of sector gears 33 to rotate in the same direction via drive assembly 4. When one set of sector gears 33 meshes with rack 32, it can push rack 32 to one side. When this set of sector gears 33 does not mesh with rack 32, and the other set of sector gears 33 meshes with rack 32, it can pull rack 32 back and push it to the other side, thus achieving back-and-forth movement. This allows rack 32 to drive connecting rod 34 to slide within movable groove 35, and connecting rod 34 drives placement frame. The placement tray 5 and the placement plate 6 move back and forth, allowing several sets of crayons to roll within the placement tray 5. When a crayon rolls to the position corresponding to the placement slot 61, it falls into the slot 61 and is placed there automatically, eliminating the need for manual placement of each crayon individually. This simplifies the process and greatly increases the convenience of the device. The drive assembly 4 includes a mounting slot 41 and a motor 44. The mounting slot 41 is located inside the workbench 11, and a main gear 42 is rotatably mounted inside the mounting slot 41. Both sides of the main gear 42 are meshed with auxiliary gears. The top of each set of auxiliary gears 43 is connected to the sector gear 33 via a connecting shaft. The motor 44 is installed at the bottom of the workbench 11. The output end of the motor 44 extends into the mounting groove 41 and is connected to the main gear 42. This structure starts the motor 44 to drive the main gear 42 to rotate. Through meshing, the main gear 42 drives the two sets of auxiliary gears 43 to rotate in the same direction. The two sets of auxiliary gears 43 can then drive the two sets of sector gears 33 to rotate in the same direction, so that the two sets of sector gears 33 can alternately mesh with the rack 32 to achieve back-and-forth movement.

[0029] It should be noted that the top of the placement frame 5 is higher than the top of the placement tray 6, so that when the crayons roll inside the placement frame 5, they can be better prevented from rolling out of the placement frame 5.

[0030] As one implementation method in this embodiment, such as Figure 3As shown, both sides of the placement frame 5 are provided with pushing components 7 for pushing crayons. Each pushing component 7 includes a support plate 71. Each support plate 71 is installed on the side of the placement frame 5. An electric push rod 72 is installed on the end of each support plate 71 away from the placement frame 5. The output end of each electric push rod 72 passes through the support plate 71 and is equipped with a movable plate 73. Each movable plate 73 is set in a groove on the side of the placement frame 5. This structure allows the electric push rod 72 to push the movable plate 73, causing the movable plate 73 to move within the placement frame 5. This pushes the crayon, which has fallen into the placement slot 61, to move at the top of the placement tray 6 until the crayon is pushed to the placement slot 61 where no crayon is placed, so that the crayon falls into the placement slot 61. This greatly increases the practicality of the device.

[0031] It should be noted that when the movable board 73 is not in use, it can be placed in the groove on the side of the placement frame 5 to block the groove and better prevent the crayons from falling out of the placement frame 5.

[0032] As one implementation method in this embodiment, such as Figure 3 As shown, collision components 9 are provided on both sides of the support frame 31. Each collision component 9 includes a collision block 91. Each collision block 91 is slidably installed inside one side of the movable groove 35. The end of each collision block 91 away from the connecting rod 34 is connected to a movable rod 92. The end of each movable rod 92 away from the collision block 91 passes through the support frame 31 and is connected to a limit plate 93. A spring 94 is sleeved on the side of each movable rod 92 near the collision block 91. This structure allows the connecting rod 34 to slide in the movable groove 35. When it moves to collide with the collision block 91, the connecting rod 34 can cause the placement frame 5 and the placement tray 6 to vibrate slightly, so that the crayons can fall into the placement groove 61 better. After the connecting rod 34 collides with the collision block 91, it can continue to move and push the collision block 91 to compress the spring 94 until the connecting rod 34 moves away from the collision block 91. The collision block 91 can then be reset by the spring force of the spring 94 for the next use.

[0033] Working principle: To automatically place crayons, simply slide the lever 84 upwards within the guide opening 85. The lever 84 will pull the baffle 83 out of the slot 82 and into the slide groove 81, opening the pick-and-place port 51. Place the placement tray 6 into the placement frame 5 through the pick-and-place port 51. Then, slide the lever 84 downwards to insert the baffle 83 into the slot 82, limiting the placement tray 6 within the placement frame 5 and preventing it from falling out and affecting the placement. At this point, several sets of crayons can be placed into the placement frame 5 according to the direction of the placement groove 61. Starting the motor 44 will drive the main gear 42 to rotate. Through meshing, the main gear 42 will drive two sets of auxiliary gears 43 to rotate in the same direction. The two sets of auxiliary gears 43 will then... The two sets of sector gears 33 rotate in the same direction. When one set of sector gears 33 meshes with the rack 32, it can push the rack 32 to one side. When the other set of sector gears 33 meshes with the rack 32, it can pull the rack 32 back and push it to the other side. This back-and-forth movement allows the rack 32 to drive the connecting rod 34 to slide in the movable groove 35. The connecting rod 34 drives the placement frame 5 and the placement tray 6 to move back and forth. In this way, several sets of crayons can roll in the placement frame 5. When the crayon rolls to the corresponding placement groove 61, the crayon can fall into the placement groove 61 and be placed there. This achieves automatic placement without the need for manual placement of each crayon, making it simpler and more convenient, and greatly increasing the convenience of the device.

[0034] Meanwhile, when the connecting rod 34 slides in the movable groove 35 and moves to collide with the collision block 91, the connecting rod 34 can cause the placement frame 5 and the placement tray 6 to vibrate slightly, so that the crayons can fall into the placement groove 61 better. After the connecting rod 34 collides with the collision block 91, it can continue to move and push the collision block 91 to compress the spring 94 until the connecting rod 34 moves away from the collision block 91. The collision block 91 can then be reset by the spring force of the spring 94 for the next use.

[0035] Finally, if some crayons do not roll into the placement slot 61, the electric push rod 72 can be activated to push the movable plate 73, so that the movable plate 73 moves within the placement frame 5, pushing the crayons that have not fallen into the placement slot 61 to move at the top of the placement tray 6 until the crayons are pushed to the placement slot 61 where there are no crayons, so that the crayons fall into the placement slot 61.

[0036] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
