Description

Technical Field

[0001] This application relates to the field of filling technology, and more particularly to a filling apparatus. Background Technology

[0002] Scented candles are a type of decorative candle, characterized by their fresh and pleasant fragrance. They are also known for their beautiful colors and delightful aroma during burning, making them popular for decorating cups to enhance a romantic atmosphere. Scented candles housed in cups are called cup candles. Making cup candles typically involves first processing the cup, then placing a wick inside, and finally pouring in candle wax to complete the product.

[0003] Some existing filling technologies employ multiple, multi-head operations, which not only result in low wax filling accuracy and long production lines, but also make it difficult to guarantee consistent filling quality. Utility Model Content

[0004] This application aims to at least solve one of the technical problems existing in the prior art. To this end, this application proposes a filling device to solve the problems of existing filling devices.

[0005] This application provides a filling device, including: a filling tank, a clamping mechanism, a positioning sensor, and a conveyor belt;

[0006] The filling tank has multiple filling ports arranged along the first direction, and the conveyor belt conveys materials along a second direction perpendicular to the first direction;

[0007] The clamping mechanism includes two clamping arms and a clamping frame arranged opposite each other in the second direction. Both clamping arms extend a set distance in the first direction. At least one clamping arm can move in the second direction to clamp the material located between the two clamping arms. Both clamping arms are slidably arranged on the clamping frame in the third direction to drive the clamped material closer to or away from the filling port.

[0008] The filling port is located between the two clamping arms, and the detection end of the positioning sensor is positioned opposite to the filling port to detect whether the material has moved to directly below the filling port.

[0009] Based on the filling device, after the material moves to the area directly below the filling nozzle, it can be regulated, fixed, and removed from the conveyor belt during the clamping and lifting process. This not only brings the material closer to the filling nozzle, resulting in better filling effect and reducing splashing, but also removes the material from the conveyor belt, preventing the conveyor belt from affecting the filling process.

[0010] Optionally, the two clamping arms form clamping surfaces facing each other, and at least one of the clamping surfaces is provided with a clamping groove that matches the shape of the sidewall of the material.

[0011] Furthermore, based on the aforementioned clamping arm, the clamping groove can be used to clamp and fix the material, thereby achieving the positioning and centering of the material and ensuring that the material is aligned with the center of the corresponding filling port.

[0012] Optionally, the clamping groove covers a circumferential surface of the material by less than 180 degrees, so that there is a set interval between the two clamping arms.

[0013] Furthermore, based on the above-mentioned clamping groove, it can be ensured that after the two clamping arms clamp the material on both sides, there is still a set interval, so as to avoid interference between the two clamping arms and thus affect the clamping effect of the material.

[0014] Optionally, the clamping groove is provided with an anti-slip pad.

[0015] Furthermore, based on the aforementioned clamping groove, the friction between the clamping groove and the material can be increased, thereby further improving the clamping stability and reliability of the clamping arm. Specifically, the anti-slip pad can be made of materials such as plastic or rubber, and the surface can be arranged with grids or stripes to further increase friction and improve clamping stability and reliability.

[0016] Optionally, the height of the clamping arm is less than the height of the material, and the clamping arm is used to clamp the area between the top and bottom of the material.

[0017] Furthermore, based on the aforementioned clamping arm, problems such as collisions between the clamping arm and the filling port can be avoided when the clamping arm lifts the material, ensuring that the material rises to the correct position, and also preventing collisions between the clamping arm and the conveyor belt when clamping and fixing the material.

[0018] Optionally, the height of the clamping arm is greater than 2 / 3 of the material height.

[0019] Furthermore, based on the aforementioned clamping arm, interference between the clamping arm and the filling port and the conveyor belt can be avoided, while ensuring that the clamping arm and the material have sufficient contact area, thereby ensuring the clamping stability between the clamping arm and the material.

[0020] Optionally, multiple sets of the filling port, the clamping mechanism, and the positioning sensor are arranged along the second direction.

[0021] Furthermore, based on the above-mentioned filling device, it is possible to simultaneously or asynchronously fill multiple rows of materials in the conveying direction of the conveyor belt, thereby significantly improving filling efficiency.

[0022] Optionally, the distance between the filling port and the conveyor belt is greater than twice the height of the material.

[0023] Furthermore, based on the aforementioned spacing between the filling port and the conveyor belt, after the material is clamped by the clamping arm, there is space between the raised material and the conveyor belt for other materials on the conveyor belt to pass through, thereby not affecting the conveying of other materials and indirectly improving the filling efficiency of all materials.

[0024] Optionally, the clamping frame is provided with a lifting component, a translation component, and a rotating component. The ends of the two clamping arms are respectively connected to the two rotating components. The rotation axis of the rotating component is parallel to the first direction. The translation component is connected to the clamping frame through the lifting component. The lifting component is used to drive the translation component to reciprocate along a third direction. The translation component is used to drive the two rotating components to reciprocate along the second direction. The rotating component is used to drive the clamping arm connected to it to rotate around its rotation axis.

[0025] Optionally, the top of the clamping groove is provided with a clamping chamfer, and an elastic pad is provided at the clamping chamfer.

[0026] Furthermore, the clamping chamfer can be an angled structure. When the clamping arms rotate at a certain angle (the tops of the two clamping slots face each other and the bottoms of the two clamping slots move away from each other), the two clamping arms can make surface contact with the side wall of the material using the inclined surface formed by the clamping chamfer. Furthermore, the clamping chamfer smoothly transitions to the lower side wall of the clamping slot through an arc-shaped clamping fillet. By setting the clamping fillet, after the clamping arms clamp and fix the material using the clamping chamfer, that is, when the translation component and the rotation component drive the two clamping arms to move closer to each other while performing a rotational action in the opposite direction, the clamping fillet can make the relative position of the material and the clamping slot change smoothly, making the whole process more stable.

[0027] The above-described one or more embodiments of this application have at least one or more of the following beneficial effects:

[0028] After the material moves to the area directly below the filling nozzle, it can be regulated, fixed, and removed from the conveyor belt during the clamping and lifting process. This not only brings the material closer to the filling nozzle, resulting in better filling and reducing splashing, but also removes the material from the conveyor belt, preventing the conveyor belt from affecting the filling process.

[0029] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

[0039] Some embodiments of this application are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of this application and are not intended to limit the scope of protection of this application.

[0040] Some existing filling technologies employ multiple, multi-head operations, which not only result in low wax filling accuracy and long production lines, but also make it difficult to guarantee consistent filling quality.

[0041] Based on this, this application provides a filling device that can regulate, fix and remove the material from the conveyor belt during the clamping and lifting process after the material moves to the bottom of the filling port. This not only brings the material closer to the filling port, improving the filling effect and reducing splashing, but also removes the material from the conveyor belt, preventing the conveyor belt from affecting the filling process.

[0042] The present application will be described in detail below through specific embodiments.

[0043] Reference Figures 1 to 6 As shown, this embodiment provides a filling device, including: a filling tank 11, a clamping mechanism 12, a positioning sensor 13, and a conveyor belt 14; the filling tank 11 has a plurality of filling ports 111 arranged along a first direction, and the conveyor belt 14 conveys material 2 along a second direction perpendicular to the first direction; the clamping mechanism 12 includes two clamping arms 121 arranged opposite to each other in the second direction and a clamping frame 122, both clamping arms 121 extending a set distance along the first direction, at least one clamping arm 121 being movable along the second direction to clamp material 2 located between the two clamping arms 121, both clamping arms 121 being slidably arranged on the clamping frame 122 along a third direction to drive the clamped material 2 closer to or away from the filling port 111; the filling port 111 is located between the two clamping arms 121, and the detection end of the positioning sensor 13 is arranged opposite to the filling port 111 to detect whether the material 2 has moved to directly below the filling port 111.

[0044] The filling device provided in this embodiment can, after the material 2 moves to the area directly below the filling port 111, straighten, fix and remove the material 2 from the conveyor belt 14 during the clamping and lifting process. This not only brings the material 2 closer to the filling port 111, making the filling effect of the material 2 better and reducing splashing, but also removes the material 2 from the conveyor belt 14, avoiding the influence of the conveyor belt 14 on the filling of the material 2.

[0045] In some embodiments, the two clamping arms 121 form clamping surfaces facing each other, and at least one clamping surface is provided with a clamping groove 1211 that matches the shape of the sidewall of the material 2.

[0046] Furthermore, based on the aforementioned clamping arm 121, the clamping groove 1211 can be used to clamp and fix the material 2, thereby achieving the centering of the material 2 and ensuring that the material 2 is aligned with the center of the corresponding filling port 111.

[0047] Continue to refer to Figure 6 As shown, the clamping groove 1211 covers a range of less than 180 degrees on the circumferential side of the material 2 so that there is a set interval between the two clamping arms 121. Specifically, the clamping groove 1211 can cover 100 to 160 degrees on the circumferential side of the material 2, which can ensure that the contact surface between the clamping groove 1211 and the material 2 is large enough, and can also avoid interference between the two clamping arms 121.

[0048] Furthermore, based on the above-mentioned clamping groove 1211, it can be ensured that the two clamping arms 121 can still have a set interval after clamping the two sides of the material 2, so as to avoid interference between the two clamping arms 121 and thus affect the clamping effect of the material 2.

[0049] In some embodiments, the clamping groove 1211 is provided with an anti-slip pad.

[0050] Furthermore, based on the aforementioned clamping groove 1211, the friction between the clamping groove 1211 and the material 2 can be increased, thereby further improving the clamping stability and reliability of the clamping arm 121 on the material 2. Specifically, the anti-slip pad can be made of materials such as plastic or rubber, and the surface can be arranged with grids or stripes to further increase friction and improve clamping stability and reliability.

[0051] In some embodiments, the height of the clamping arm 121 is less than the height of the material 2, and the clamping arm 121 is used to clamp the area between the top and bottom of the material 2.

[0052] Furthermore, based on the aforementioned clamping arm 121, it is possible to avoid problems such as the clamping arm 121 colliding with the filling port 111 when the clamping arm 121 lifts the material 2, ensuring that the material 2 rises to the correct position, and also preventing the clamping arm 121 from colliding with the conveyor belt 14 when clamping and fixing the material 2.

[0053] Optionally, the height of the clamping arm 121 is greater than 2 / 3 of the height of the material 2.

[0054] Furthermore, based on the aforementioned clamping arm 121, it is possible to avoid interference between the clamping arm 121 and the filling port 111 and the conveyor belt 14, while ensuring that the clamping arm 121 and the material 2 have sufficient contact area, thereby ensuring the clamping stability between the clamping arm 121 and the material 2.

[0055] Optionally, multiple sets of filling port 111, clamping mechanism 12 and positioning sensor 13 are arranged along the second direction.

[0056] Furthermore, based on the above-mentioned filling device, it is possible to simultaneously or asynchronously fill multiple rows of materials 2 in the conveying direction of the conveyor belt 14, thereby significantly improving filling efficiency.

[0057] Optionally, the distance between the filling port 111 and the conveyor belt 14 is greater than twice the height of the material 2.

[0058] Furthermore, based on the aforementioned spacing between the filling port 111 and the conveyor belt 14, after the material 2 is clamped by the clamping arm 121, there is space between the raised material 2 and the conveyor belt 14 for other materials 2 on the conveyor belt 14 to pass through, thereby not affecting the conveying of other materials 2 and indirectly improving the filling efficiency of all materials 2.

[0059] Continue to refer to Figures 1 to 4 as well as Figure 6 As shown, the clamping frame 122 is equipped with a lifting assembly 123, a translation assembly 124, and a rotating assembly 125. The ends of the two clamping arms 121 are respectively connected to the two rotating assemblies 125. The rotation axis of the rotating assembly 125 is parallel to the first direction. The translation assembly 124 is connected to the clamping frame 122 through the lifting assembly 123. The lifting assembly 123 is used to drive the translation assembly 124 to reciprocate along the third direction, thereby causing the clamping arms 121 to move closer to or away from the filling port 111. The translation assembly 124 is used to drive the two rotating assemblies 125 respectively. The component 125 reciprocates along the second direction. The rotating component 125 is used to drive the clamping arm 121 connected to it to rotate around its rotation axis. The translation component 124 may include two translation blocks 1241. The two rotating components 125 are correspondingly arranged on the two translation blocks 1241. The translation component 124 can drive the two translation blocks 1241 to reciprocate along the second direction, thereby driving the rotating component 125 and the clamping arm 121 to reciprocate in the second direction. The two translation blocks 1241 can perform synchronous or asynchronous movements.

[0060] Optionally, the top of the clamping groove 1211 is provided with a clamping chamfer 12111, and an elastic pad is provided at the clamping chamfer 12111.

[0061] Further, continue to refer to Figure 5 As shown, the clamping chamfer 12111 can be an angled structure. When the clamping arm 121 rotates at a certain angle (the tops of the two clamping grooves 1211 face each other and the bottoms of the two clamping grooves 1211 move away from each other), the two clamping arms 121 can make surface contact with the side wall of the material 2 using the inclined surface formed by the clamping chamfer 12111. Furthermore, the clamping chamfer 12111 smoothly transitions to the side wall of the lower part of the clamping groove 1211 through the arc-shaped clamping fillet 12112. By setting the clamping fillet 12112, after the clamping arm 121 clamps and fixes the material 2 using the clamping chamfer 12111, that is, when the translation component 124 and the rotation component 125 drive the two clamping arms 121 to move closer to each other and perform a rotation action in the opposite direction, the clamping fillet 12112 can make the relative position of the material 2 and the clamping groove 1211 change smoothly, and the whole process is more stable.

[0062] Specifically, before the two clamping arms 121 approach each other to clamp the material 2, they rotate a certain angle so that the top of the clamping grooves 1211 on the two clamping arms 121 first contacts the outer wall of the material 2. When both clamping grooves 1211 on both sides are in contact with the outer wall of the material 2, the two clamping arms 121 continue to apply a clamping force to the material 2. Furthermore, through their own rotation, the two clamping arms 121 use the friction with the outer wall of the material 2 to lift the material 2 to leave the conveyor belt 14 of the filling line. It should be noted that the rotation directions of the two clamping arms 121 are opposite.
