Description

Technical Field

[0001] The present invention relates to the technical field of puzzle dust removal, and specifically relates to a puzzle dust removal device. Background Art

[0002] A puzzle is composed of a series of geometric "puzzle pieces", which can form a complete image or shape after being arranged and combined.

[0003] When puzzles are produced, they are generally scattered after being stamped and formed into various "puzzle pieces". A large amount of dust is generated during the production and scattering processes and is mixed with the "puzzle pieces". When people play with puzzles, the dust is often inhaled into the body or splashed into the eyes. Especially for children who love to play with puzzles, it poses a potential health and safety hazard at any time.

[0004] In the prior art, a published document with the publication number CN 222219755 U and the name of a bulk device with a dust removal function uses a vibration motor to drive an inclined guide plate to vibrate to remove dust from the scattered small puzzles. However, there are many drawbacks to using this structure of the guide plate for dust removal. If the inclination angle of the guide plate is large, after the small puzzles fall onto the guide plate, they will quickly roll out of the outlet of the housing directly, and the time for vibration dust removal is very short, greatly reducing the dust removal effect of the guide plate. If the inclination angle of the guide plate is small, the small puzzles will accumulate on the guide plate, the material discharge is not smooth, and the accumulated small puzzles will also seriously affect the dust removal effect and efficiency. Therefore, this prior art can only meet the need to remove the debris mixed in the small puzzles and cannot meet the need for puzzle dust removal. Summary of the Invention

DETAILED DESCRIPTION

[0022] like Figures 1 - 3 As shown, the present invention provides a jigsaw dust removal device, including a support frame 1, a conveyor belt 2 arranged on the support frame 1 and performing circular motion, and also including an air guide hopper 3, a vibration frame 4 and a drop hopper 5 arranged in sequence below the conveyor belt 2, an exhaust fan 6 arranged on one side of the support frame 1, and a vibration motor 7 fixed at the lower end of the vibration frame 4; the conveyor belt 2 is provided with air holes, the air guide hopper 3 opens upward and corresponds to the lower side of the input end of the conveyor belt 2, the suction end of the exhaust fan 6 is connected to one side of the air guide hopper 3, the upper end of the vibration frame 4 is in contact with the lower end of the conveyor belt 2, and the drop hopper 5 opens upward and is below the front side of the output end of the conveyor belt 2.

[0023] The conveyor belt 2 is of a mesh structure, and the mesh size is smaller than that of the puzzle pieces. The mesh holes can be circular or square. The conveyor belt 2 is installed on the support frame 1 and can perform circular motion. The upper end of the conveyor belt 2 is the conveying end face for carrying and conveying the puzzle. At the lower end of the conveying end face of the conveyor belt 2, that is, at the lower end of the upper conveying part of the conveyor belt 2, a wind guide hopper 3, a vibration frame 4 and a blanking hopper 5 are successively installed along the conveying direction. The wind guide hopper 3 corresponds to the lower part of the feeding end of the conveyor belt 2, and the blanking hopper 5 corresponds to the lower part in front of the output end of the conveyor belt 2. The wind guide hopper 3 is of a square funnel-shaped structure with an opening at the upper end and one side. The width of the opening at the upper end of the wind guide hopper 3 is not less than the width of the conveyor belt 3, and the length is adjusted according to the actual situation. The suction end of the exhaust fan 6 is connected to the opening on one side of the wind guide hopper 3 through a pipeline. After the puzzle is broken up into scattered puzzle pieces, it is conveyed to the output end of the conveyor belt 2. The conveyor belt 2 is provided with a plurality of ventilation holes. The exhaust fan 6 sucks air at the lower end of the conveyor belt 2 through the wind guide hopper 3. The debris and attached dust of the puzzle pieces pass through the ventilation holes of the conveyor belt 2 and are sucked away under the suction of the exhaust fan 6 and the guidance of the wind guide hopper 3. The wind guide hopper 3 can not only guide the debris and dust, but also converge the air flow of the exhaust fan 6; the spelling blocks are stably conveyed on the conveyor belt 2. When passing through the vibration frame 4, the vibration motor 7 drives the vibration frame 4 to vibrate, driving the conveyor belt 2 to vibrate synchronously. The puzzle pieces on the conveyor belt 2 tremble or even roll over, and the dust attached to the puzzle pieces is further shaken off, and the debris mixed between the puzzle pieces is also shaken off and falls downward through the ventilation holes on the conveyor belt 2 for further dust removal; the blanking hopper 5 is of a square funnel-shaped structure with openings at the upper and lower ends. The width of the opening at the upper end of the blanking hopper 5 is greater than the width of the conveyor belt 2, and the length is adjusted according to the actual situation. The puzzle pieces continue to be conveyed on the conveyor belt 2 until they fall into the blanking hopper 5 from the output end of the conveyor belt 2. A receiving box can be placed at the lower end of the blanking hopper 5 to collect the falling puzzle pieces. This design uses the perforated conveyor belt 2 to stably convey the puzzle pieces, and dust removal is carried out by two methods of suction and vibration during the conveying process, greatly improving the dust removal effect and efficiency.

[0024] As Figure 3 shown, a connecting spring 8 is arranged between the vibration frame 4 and the support frame 1. The lower end of the connecting spring 8 is fixed to the support frame 1, and the upper end is fixed to the vibration frame 4.

[0025] The vibration frame 4 is connected to the support frame 1 through the connecting spring 8. When the vibration motor 7 drives the vibration frame 4 to vibrate, it does not affect the stability of the support frame 1. And the vibration effect of the vibration frame 4 will not be reduced due to the support frame 1.

[0026] As Figure 3 shown, the vibration frame 4 includes a hollow plate 9 fixed to the upper end of the connecting spring 8 and a resisting rod 10 fixed to the upper end of the hollow plate 9. The resisting rod 10 is parallel to the conveyor belt 2 and lies flat along the conveying direction of the conveyor belt 2.

[0027] The hollow plate 9 adopts a hollow design and is light in weight, which reduces the power requirement for the vibration motor 7. The hollow plate 9 does not directly contact the conveyor belt 2, but contacts the conveyor belt 2 through the outer periphery of the resistance rod 10, thereby reducing the contact area with the conveyor belt 2, ensuring the vibration transmission between the vibration frame 4 and the conveyor belt 2, and reducing the friction resistance of the conveyor belt 2. The length direction of the resistance rod 10 is consistent with the conveying direction of the conveyor belt 2, further reducing the friction resistance of the conveyor belt 2, so that the conveyor belt 2 can maintain a uniform and stable conveying.

[0028] like Figure 3 As shown, the two ends of the abutment rod 10 are bent downwards so that the arc surface of the outer periphery of the abutment rod 10 contacts the conveyor belt 2, effectively preventing the ends of the abutment rod 10 from causing obstruction and damage to the conveyor belt 2.

[0029] like Figure 3 As shown, it also includes a dust collection drawer 11 arranged on the support frame 1 and located below the vibration frame 4.

[0030] The dust collection drawer 11 is a drawer-type structure, mainly composed of two slide rails and a drawer slidably installed between the slide rails. The drawer opens upward and can collect dust and debris dropped by the vibration of the puzzle pieces on the conveyor belt 2. The dust and debris collected in the drawer can be further processed by pulling out the drawer, which is very convenient to collect and use.

[0031] like Figure 2 As shown, it also includes a filter bag 12 arranged at the output end of the exhaust fan 6.

[0032] The filter bag 12 can collect dust and debris extracted by the exhaust fan.

[0033] like Figure 1 As shown, the output end of the conveyor belt 2 is higher than the input end.

[0034] With the vibration of the conveyor belt 2 by the vibration frame 4, the jigsaw puzzle pieces on the conveyor belt 2 can roll over more easily, further improving the dust removal effect.

[0035] like Figures 2 - 3 As shown, the support frame 1 includes a horizontal base frame 13, a universal wheel 14 arranged at the lower end of the horizontal base frame 13, a vertical stand 15 relatively arranged at the upper end of the horizontal base frame 13, an inclined conveying frame 16 arranged at the upper end of the vertical stand 15, conveying rollers 17 arranged at both ends of the inclined conveying frame 16, guide rollers 18 respectively arranged on the two vertical stands 15 and located below the conveying rollers 17, and a conveying motor 19 arranged on the horizontal base frame 13; the conveying motor 19 is transmission-connected to the conveying roller 17 at one end of the inclined conveying frame 16, and the conveyor belt 2 is arranged around the two conveying rollers 17 and the two guide rollers 18.

[0036] The support frame 1 is composed of a horizontal bottom frame 13, a vertical upright frame 15, and an inclined conveyor frame 16. The universal wheels 14 at the lower end of the support frame 1 facilitate movement. The conveyor belt 2 is arranged around the conveyor rollers 17 and the guide rollers 18 to form a rectangular circular motion track, with a simple structure and convenient production and assembly. The inclined conveyor frame 16 is designed to be inclined, and the upper surface of the conveyor belt 2 is directly installed on the inclined conveyor frame 16, thus forming an inclined conveyor belt 2, further improving the convenience of production and assembly.

[0037] As Figures 2 - 3 shown, the conveyor belt 2 includes a conveying section 20 between the conveyor rollers 17, a turning section between the guide rollers 18, a first turning section and a second turning section respectively between the conveyor rollers 17 and the guide rollers 18. The air guide hopper 3, the vibration frame 4, and the blanking hopper 5 are located below the conveying section 20 of the conveyor belt 2, and the upper end of the vibration frame 4 abuts against the conveying section 20. The installation position of the conveyor belt 2 is further defined to make the conveyor belt 2 run more stably and the assembly more convenient.

[0038] As Figures 1 - 3 shown, it further includes a front baffle 21 and a rear baffle 22 arranged at the upper end of the support frame 1 and above the input end and the output end of the conveyor belt 2, a feeding cover 23, a middle cover 24, and a discharging cover 25 arranged on the support frame 1 in sequence along the conveying direction of the conveyor belt 2 and located between the front baffle 21 and the rear baffle 22; the feeding cover 23, the middle cover 24, and the discharging cover 25 are all in an n-shaped structure and cover above the conveyor belt 2. The feeding cover 23 is located above the input end of the conveyor belt 2 and corresponds to the air guide hopper 3. The middle cover 24 is arranged above the middle of the conveyor belt 2 and corresponds to the vibration frame 4. The discharging cover 25 is arranged above the output end of the conveyor belt 2 and corresponds to the blanking hopper 5. A plurality of through holes are provided on both the feeding cover 23 and the middle cover 24, and a feeding port 26 is provided at the upper end of the feeding cover 23.

[0039] Adding the feeding cover 23, the middle cover 24, and the discharging cover 25 at the upper end of the conveyor belt 2 for the puzzle pieces blocks the upper end of the conveyor belt 2 to prevent the puzzle pieces from rolling out of the conveyor belt 2 when vibrating. At the same time, the feeding port 26 is reserved on the feeding cover 23 for convenient feeding. A plurality of through holes are provided on both the feeding cover 23 and the middle cover 24 to form a hollow structure for convenient air flow.
