Abstract
Description
Technical Field
[0001] This utility model relates to the field of feeding equipment technology, specifically to a feeding device for bagged pigments. Background Technology
[0002] The raw materials for ink processing include powdered pigments, which are usually packaged in bags, i.e., bagged pigments. During ink processing, a sand mill is needed to grind the pigments. A feed pump is used to feed the sand mill; the feed pump's inlet is connected to the inside of the bagged pigment via a feed pipe, and the feed pump draws the pigment into the sand mill.
[0003] To reduce pollution to the work environment, see Figure 12 The factory area includes a storage room 1 where bagged pigments are stored. A feeding pipe 3 extends into the storage room 1 from the end furthest from the feed pump. The end of the feeding pipe 3 inside the storage room 1 is inserted into the packaging bag of the pigment. The feeding pipe 3 is made of sufficiently long corrugated plastic tubing. During feeding, the bagged pigments remain within the enclosed space of the storage room 1, preventing the pigments from spreading to other areas.
[0004] As the pigment inside the packaging bag is gradually removed, the bag gradually loses its pigment filling, causing it to gradually dry out and wrinkle. This leaves pigment residue in the wrinkles, making it difficult to completely remove the pigment from the packaging bag and resulting in waste. Utility Model Content
[0005] To address the aforementioned shortcomings of existing technologies, this invention proposes a feeding device for bagged pigments. This invention can maintain the packaging bag in an open state, reduce wrinkles and dead corners in the packaging bag, reduce pigment residue, and reduce waste.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0007] A feeding device for bagged pigments includes a storage chamber containing bagged pigments, each bagged pigment comprising a packaging bag. A feeding pipe is located on the side of the storage chamber, one end of which is inside the packaging bag, and the other end is connected to a feed pump. A support is located on the inner side of the storage chamber, with a support ring fitted over the packaging bag. The opening of the packaging bag is turned outwards to the outside of the support ring. A movable frame is located above the support, connected to the side of the storage chamber via a lifting mechanism. A pressure ring is located on the movable frame, with a clamping ring at its bottom, fitted over the opening of the packaging bag. A support plate is located on the pressure ring inside the packaging bag. The feeding pipe is located in the middle of the pressure ring.
[0008] Furthermore, the storage chamber has a vertical hole on its side and a sealing strip on its outer side. The sealing strip is used to cover the vertical hole, and both the upper and lower ends of the sealing strip are connected to the outer side of the storage chamber. The outer side of the storage chamber is also equipped with the lifting mechanism.
[0009] The movable frame includes a frame body and a sliding plate. The frame body is located in a vertical hole, and the sliding plate is located on the outer side of the storage compartment and between the sealing strip. The horizontal end of the sliding plate extends out from the side of the sealing strip and is connected to the lifting mechanism.
[0010] Furthermore, the pressure ring is provided with a sliding hole, and the support plate slides in the vertical direction with the sliding hole. The top of the pressure ring is provided with a pressing mechanism, which is used to push the support plate down.
[0011] Furthermore, the pressing mechanism includes a guide rod, a spring, and a pressure cap. The guide rod is located on the top of the pressure ring, and the top of the guide rod is provided with a pressure cap. The top of the support plate is provided with a slide block, which is slidably connected to the guide rod in the vertical direction. The spring is sleeved on the guide rod, with the top of the spring abutting against the pressure cap and the bottom of the spring abutting against the slide block.
[0012] Furthermore, the support plate is an arc-shaped plate.
[0013] Furthermore, the support plate is provided with multiple supports along the circumference of the pressure ring.
[0014] Furthermore, the hoop has a soft pad on the side facing the support ring, and the soft pad has a guide slope at the lower part of the side facing the support ring.
[0015] The beneficial effects of this utility model are:
[0016] 1. In this utility model, the support ring and the hoop ring can cooperate to clamp the opening of the packaging bag of bagged pigment. The support plate can be inserted into the packaging bag. As the pigment inside the packaging bag is gradually drawn away by the feed pump, the packaging bag gradually loses the filling of pigment. The packaging bag, which would have gradually shrunk and wrinkled, is supported by the support plate, preventing the packaging bag from shrunk and wrinkled inward, keeping the packaging bag open, avoiding pigment residue in the wrinkled dead corners, and making it easier to draw out the pigment inside the packaging bag more thoroughly, which helps to reduce waste.
[0017] 2. By placing the lifting mechanism on the outside of the storage room, workers can easily inspect and maintain the lifting mechanism from outside the storage room. Furthermore, the installation of the sliding plate and sealing strip prevents dust inside the storage room from spreading outside through the vertical openings, thus helping to ensure air quality outside the storage room, without hindering the lifting mechanism from driving the movable frame up and down.
[0018] 3. By setting sliding holes on the pressure ring to allow the support plate to slide up and down, and by setting a pressing mechanism including a guide rod, spring, and pressure cap, the support plate can adapt to the amount of pigment stored inside the packaging bag. When the amount of pigment stored inside the packaging bag is large, the resistance to inserting the support plate into the packaging bag is greater. At this time, the support plate can overcome the elastic force of the spring and stop moving downward. When the amount of pigment stored inside the packaging bag decreases, the resistance of the pigment to the support plate decreases, and the support plate can move downward under the push of the elastic force of the spring. The gradually moving support plate replaces the pigment and opens the packaging bag. Thus, on the one hand, it reduces the difficulty of inserting the support plate into the packaging bag; on the other hand, it avoids the support plate being inserted into the packaging bag when the amount of pigment is large, reducing the risk of the packaging bag being damaged, which is conducive to improving the safety of the packaging bag, facilitating the reuse of the packaging bag, and saving resources.
[0019] 4. By using an arc-shaped plate as a support, the arc-shaped surface of the support can be used to fit the packaging bag, preventing the support from scratching the packaging bag, further improving the safety of the packaging bag, facilitating the reuse of the packaging bag, and helping to save resources.
[0020] 5. By placing a soft pad on the side of the hoop facing the support ring, the distance between the hoop and the support ring can be reduced, thereby improving the reliability of the hoop and the support ring in clamping the bag opening. Attached Figure Description

[0045] To better understand this utility model, it will be further described below with reference to the accompanying drawings. It is worth noting that in the description of this utility model, terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings. They are used for the convenience of describing this utility model and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0046] Example:
[0047] See Figure 10 A feeding device for bagged pigments includes a storage chamber 1 for storing bagged pigments. The bagged pigments include a packaging bag 2 and powdered pigment contained within the packaging bag 2.
[0048] See Figure 10 The storage chamber 1 has a through hole 11 on the top side. One end of the feeding pipe 3 extends into the interior of the storage chamber 1 through the through hole 11. The end of the feeding pipe 3 entering the storage chamber 1 is used to insert into the interior of the packaging bag 2. The end of the feeding pipe 3 located outside the storage chamber 1 is connected to the inlet of the feeding pump. The outlet of the feeding pump is connected to the sand mill.
[0049] When the feed pump starts, the pigment inside the packaging bag 2 is pumped into the sand mill through the feed pipe 3 for grinding. The feed pipe 3 is a flexible hose of sufficient length, such as a corrugated plastic pipe. As the amount of pigment inside the packaging bag 2 gradually decreases, the sufficiently long feed pipe 3 can extend and move downwards due to the decrease in pigment and its own gravity, maintaining contact between the feed pipe 3 and the pigment, thus ensuring effective feeding.
[0050] See Figure 9 A bracket 4 is bolted to the inner side of storage room 1, and a support ring 5 is welded to the bracket 4. (See also...) Figure 11 The support ring 5 is used to fit over the outside of the packaging bag 2, and the opening of the packaging bag 2 is manually folded over to the outside of the support ring 5 by the worker.
[0051] See Figure 5 and Figure 6 The storage room 1 has a vertical opening 12 on its side. (See also...) Figure 7 and Figure 8 A sealing strip 13 is provided on the outer side of the storage chamber 1. The sealing strip 13 is used to cover the vertical hole 12. Both the upper and lower ends of the sealing strip 13 are fixed to the outer side of the storage chamber 1 by bolts. A lifting mechanism 6 is also fixedly installed on the outer side of the storage chamber 1. The lifting mechanism 6 can be a hydraulic cylinder, a pneumatic cylinder, or an electric push rod. The piston rod of the lifting mechanism 6 is set upward.
[0052] See Figures 1 to 4 A movable frame 7 is located above the support 4. (See also...) Figure 2 The movable frame 7 includes a frame body 71 and a sliding plate 72, which are welded and fixed together. See also... Figure 9 The frame 71 is installed within the vertical hole 12. (See also...) Figure 8 The slide plate 72 is located between the outer side of the storage chamber 1 and the sealing strip 13. The horizontal end of the slide plate 72 extends from the side of the sealing strip 13. The horizontal end of the slide plate 72 extending from the side of the sealing strip 13 is fixedly installed together with the piston rod of the lifting mechanism 6.
[0053] When the piston rod of the lifting mechanism 6 extends upward, the slide plate 72 moves upward between the sealing strip 13 and the outer side of the storage chamber 1, and the frame 71 moves upward within the vertical hole 12; when the piston rod of the lifting mechanism 6 retracts downward, the slide plate 72 moves downward between the sealing strip 13 and the outer side of the storage chamber 1, and the frame 71 moves downward within the vertical hole 12.
[0054] Therefore, by placing the lifting mechanism 6 on the outside of the storage room 1, it is convenient for workers to inspect and maintain the lifting mechanism 6 from outside the storage room 1. Furthermore, the installation of the sliding plate 72 and the sealing strip 13 can prevent dust inside the storage room 1 from spreading to the outside of the storage room 1 through the vertical hole 12 without hindering the lifting mechanism 6 from driving the movable frame 7 to rise and fall, which is beneficial to ensuring the air quality outside the storage room 1.
[0055] See Figure 2 The movable frame 7 is equipped with a pressure ring 8, which is an integral part of the movable frame 7. (See also...) Figure 10 The feed pipe 3 passes through the middle of the pressure ring 8. (See also...) Figure 4 A retaining ring 9 is welded and fixed to the bottom surface of the pressure ring 8. When the lifting mechanism 6 drives the movable frame 7 to move downward, the movable frame 7 drives the pressure ring 8 to move downward, and the pressure ring 8 drives the retaining ring 9 to move downward. See [reference needed]. Figure 11 When the hoop 9 moves down, the hoop 9 can be fitted onto the outside of the bag opening of the packaging bag 2, so that the bag opening of the packaging bag 2 is sandwiched between the hoop 9 and the support ring 5, which reduces the probability of the bag opening of the packaging bag 2 falling off the support ring 5 and improves the stability of the packaging bag 2 being opened.
[0056] See Figure 1 , Figure 3 and Figure 4 The pressure ring 8 is provided with several support plates 10 around its circumference. When the lifting mechanism 6 drives the movable frame 7 to move down, the movable frame 7 drives the pressure ring 8 to move down, and the pressure ring 8 drives the support plates 10 to move down. The support plates 10 are gradually inserted into the inside of the packaging bag 2. As the pigment inside the packaging bag 2 is gradually drawn away by the feed pump, the packaging bag 2 gradually loses its pigment filling. The packaging bag 2, which would have gradually shrunk and wrinkled, is supported by the support plates 10, preventing the packaging bag 2 from shrunk and wrinkled inward, keeping the packaging bag 2 in an open state, avoiding pigment residue in the wrinkled corners, and making it easier to remove the pigment inside the packaging bag 2 more thoroughly, which helps to reduce waste.
[0057] The working principle of this embodiment is as follows:
[0058] S1. The worker first moves the bagged pigment to the bottom of the support ring 5, then opens the bag opening of the packaging bag 2 of the pigment, and then folds the bag opening of the packaging bag 2 outward to the outside of the support ring 5, so that the bag opening of the packaging bag 2 is turned outward to the outside of the support ring 5. Then, one end of the feeding tube 3 is inserted into the packaging bag 2.
[0059] S2. The lifting mechanism 6 drives the movable frame 7 to move down, the movable frame 7 drives the pressure ring 8 to move down, the pressure ring 8 drives the hoop ring 9 and the support plate 10 to move down together, the hoop ring 9 gradually fits on the outside of the bag opening of the packaging bag 2, so that the bag opening of the packaging bag 2 is clamped between the hoop ring 9 and the support ring 5. At the same time, the support plate 10 is inserted into the inside of the packaging bag 2.
[0060] S3. The feed pump draws the pigment inside the packaging bag 2 into the sand mill for grinding through the feed pipe 3. As the pigment inside the packaging bag 2 is gradually drawn away by the feed pump, the packaging bag 2 gradually loses its pigment filling. The packaging bag 2, which would have gradually shrunk and wrinkled, is supported by the support plate 10, which prevents the packaging bag 2 from shrunk and wrinkled inward, keeps the packaging bag 2 in an open state, avoids pigment residue in the wrinkled dead corners, and makes it easier to draw away the pigment inside the packaging bag 2 more thoroughly, which helps to reduce waste.
[0061] Example 2:
[0062] This embodiment 2 is an improvement upon embodiment 1:
[0063] See Figure 4 A soft pad 91 is attached and fixed to the side of the hoop 9 facing the support ring 5. The soft pad 91 can be a sponge pad or a rubber pad. See [reference needed] Figure 11 The cushion 91 has a guide slope 911 on the lower part of the side facing the support ring 5.
[0064] See Figure 11 When the lifting mechanism 6 drives the hoop 9 to move down, the hoop 9 drives the soft pad 91 to move down together, so that the bag opening of the packaging bag 2 is clamped between the soft pad 91 and the support ring 5, which further improves the reliability of opening the bag opening of the packaging bag 2.
[0065] As can be seen from the above description, by setting a soft pad 91 on the side of the hoop 9 facing the support ring 5, the distance between the hoop 9 and the support ring 5 can be reduced, thereby improving the reliability of the hoop 9 and the support ring 5 in clamping the mouth of the packaging bag 2.
[0066] Example 3:
[0067] This embodiment 3 is an improvement upon embodiment 1 or embodiment 2:
[0068] See Figures 1 to 4 The pressure ring 8 has three sliding holes 81 in its circumference. The sliding holes 81 are arc-shaped holes. The support plate 10 is located in the sliding holes 81. The support plate 10 is an arc-shaped plate. The support plate 10 and the sliding holes 81 slide in a vertical direction.
[0069] See Figure 2 and Figure 11The top of the pressure ring 8 is provided with a pressing mechanism 20, which is used to push the support plate 10 downward. The pressing mechanism 20 includes a guide rod 201, a spring 202 and a pressure cap 203. The guide rod 201 is welded and fixed to the top of the pressure ring 8, and the pressure cap 203 is welded and fixed to the top of the guide rod 201. The top of the support plate 10 is provided with a slide seat 101, which is slidably connected to the guide rod 201 in the vertical direction. The spring 202 is sleeved on the guide rod 201, with the top of the spring 202 abutting against the pressure cap 203 and the bottom of the spring 202 abutting against the slide seat 101. The elastic force of the spring 202 is used to push the slide seat 101 and the support plate 10 downward together.
[0070] When the lifting mechanism 6 drives the pressure ring 8 to move downwards, the pressure ring 8 drives the support plate 10 to move downwards, and the support plate 10 gradually inserts into the interior of the packaging bag 2. (See also...) Figure 11 In the left figure, when the amount of pigment stored in the packaging bag 2 is relatively large, the resistance to the insertion of the support plate 10 into the pigment is greater, resulting in a shallow insertion depth of the support plate 10 into the pigment. At this time, the support plate 10 overcomes the elastic force of the spring 202 and pushes the spring 202 upward. Figure 11 In the left image, packaging bag 2 is filled with pigment, so it is in an open state. (See also...) Figure 11 As shown in the right figure, as the pigment is gradually removed, the amount of pigment in the packaging bag 2 gradually decreases. The resistance from the pigment to the support plate 10 decreases, and the support plate 10 is pushed down by the spring 202. The gradually moving support plate 10 replaces the pigment to open the packaging bag 2, preventing the packaging bag 2 from drying out and wrinkling under the suction of the feed pump. This helps to reduce the dead corners of the packaging bag 2 and reduce the amount of pigment remaining in the dead corners, thus reducing waste.
[0071] As can be seen from the above process, by setting a sliding hole 81 on the pressure ring 8 to allow the support plate 10 to slide up and down, and setting a pressing mechanism 20 including a guide rod 201, a spring 202, and a pressure cap 203, the support plate 10 can adapt to the amount of pigment stored inside the packaging bag 2. When the amount of pigment stored inside the packaging bag 2 is large, the resistance to inserting the support plate 10 into the packaging bag 2 is large. At this time, the support plate 10 can overcome the elastic force of the spring 202 and stop moving downward. When the amount of pigment stored inside the packaging bag 2 decreases, the resistance of the pigment to the support plate 10 decreases, and the support plate 10 can move downward under the push of the elastic force of the spring 202. The gradually moving support plate 10 replaces the pigment to open the packaging bag 2. Thus, on the one hand, the difficulty of inserting the support plate 10 into the packaging bag 2 is reduced, and on the other hand, the support plate 10 is prevented from being inserted into the packaging bag 2 when the amount of pigment is large, reducing the risk of the packaging bag 2 being damaged. This is beneficial to improving the safety of the packaging bag 2, facilitating the reuse of the packaging bag 2, and saving resources.
[0072] Furthermore, by using an arc-shaped plate as the support plate 10, the arc-shaped surface of the support plate 10 can be used to fit the packaging bag 2, preventing the support plate 10 from scratching the packaging bag 2, further improving the safety of the packaging bag 2, facilitating the reuse of the packaging bag 2, and helping to save resources.
[0073] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
