Description

Technical Field

[0001] This utility model relates to the field of dispensing machine technology, specifically to an anti-clogging dispensing structure for a dispensing machine. Background Technology

[0002] A dispensing machine, also known as a glue applicator, glue dripper, glue applicator, or glue potting machine, is a specialized automated machine for controlling fluids. It dispenses or coats fluids onto the surface or interior of a product, enabling three-dimensional or four-dimensional dispensing with precise positioning and control, preventing stringing, leakage, and dripping. It can be used to apply dots, lines, circles, or arcs.

[0003] However, in actual use, when using a dispensing machine, the corresponding glue needs to be transported to the dispensing head through a pipeline. As the transportation distance is long, the exposure of the transportation pipeline will cause the temperature to drop, resulting in the glue curing. It is necessary to make effective adjustments to the dispensing structure to avoid blockage. Utility Model Content

[0004] The purpose of this invention is to provide an anti-clogging dispensing structure for a dispensing machine, which solves the problem of easy clogging in existing dispensing structures.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an anti-clogging dispensing structure for a dispensing machine, including a mounting plate, a lifting plate at one top end of the mounting plate, a conveying rod fixedly connected to the center of the top of the lifting plate, a receiving box slidably connected to the top of the conveying rod, an insulation box installed on the side wall of the conveying rod near the receiving box, and a feeding pump installed at the top end of the mounting plate near the lifting plate.

[0006] An electric heating rod is installed inside the container at the end away from the insulated box, and a heat-conducting pipe is installed through the inside of the container at the end closer to the insulated box.

[0007] A delivery pump is fixedly connected to the top of the interior of the insulated box, and the delivery pump is connected to one end of the bottom of the container. An insulated cylinder is fixedly connected to the bottom of the delivery pump.

[0008] Preferably, both ends of the lifting plate are internally threaded with lead screws, and the bottom of the lead screws passes through the interior of the mounting plate and is connected to a drive motor.

[0009] Preferably, the interior of the receiving box is hollow, and a feeding conduit is provided on one side of the receiving box. The interior of the feeding pump is connected to the receiving box through the feeding conduit, and the length of the feeding conduit is greater than the distance between the feeding pump and the end of the conveying rod away from the lifting plate.

[0010] Preferably, the top of the heat-conducting pipe is arc-shaped and penetrates the interior of the container, and both ends of the heat-conducting pipe are connected to the interior of the insulation box. The diameter of the insulation cylinder is smaller than the inner diameter of the insulation box.

[0011] Preferably, the inside of the conveying rod is provided with a groove on the side near the heat preservation box, and a threaded rod is provided through the inside of the groove. A sliding block is threadedly connected to the outer wall of the threaded rod. The sliding block is slidably connected to the inside of the groove of the conveying rod. One end of the threaded rod passes through the inside of the conveying rod and is connected to a rotating motor.

[0012] Preferably, one end of the conveying rod is fixedly connected to the top of the lifting plate, and a fixing block is fixedly connected to the bottom end of the conveying rod near the lifting plate.

[0013] Preferably, the top of the fixing block is provided with a receiving groove near the receiving box, and the receiving groove is provided with an arc-shaped heating wire inside. The bottom end of the heat preservation cylinder passes through the inside of the heat preservation box and is connected to an extruder. The diameter of the receiving groove is larger than the outer wall diameter of the extruder. The extruder can be moved into the receiving groove and heated by the heating wire inside the receiving groove.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] 1. The lifting plate drives the conveyor rod to move up and down, and the rotating motor is started at the same time. The rotating motor drives the threaded rod to rotate, which allows the sliding block to move along the side groove of the conveyor rod, thereby moving the insulation box. The insulation box drives the extruder head at the bottom to the corresponding position. The conveying pump is started, which can transport the material inside the top container to the insulation cylinder at the bottom. Finally, the material is extruded through the extruder head at the bottom of the insulation cylinder to complete the dispensing operation. During use, the dispensing position and height can be effectively adjusted, which is convenient for operation in different positions. At the same time, since the conveying pump first transports the material to the insulation cylinder and then extrudes it through the extruder head, the insulation cylinder can realize the storage and mixing of materials, which can effectively maintain the continuity and uniformity of extrusion.

[0016] 2. The electric heating rod is activated to heat the material inside the container, preventing it from cooling down and solidifying. Simultaneously, when conveying the material to the bottom extruder, it is directly pumped into the insulation cylinder via the pump at the bottom of the container, reducing the conveying distance and preventing temperature loss. Furthermore, since the outer wall of the heat-conducting pipe is connected to the inside of the container, heat can be effectively transferred from the inside of the container to the insulation cylinder, thus heating the outer wall of the insulation cylinder and further preventing temperature drop. Even if solidification occurs at the extruder, the insulation cylinder can be moved to the top of the fixed block, allowing the extruder to move into the container groove. The heating wire inside the container groove heats the extruder, effectively remelting the material and clearing any solidification or blockage. Attached Figure Description

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] This utility model provides, for example Figure 1-5 The diagram illustrates an anti-clogging dispensing structure for a dispensing machine, comprising a mounting plate 1, a lifting plate 2 at one top end of the mounting plate 1, a conveying rod 3 fixedly connected to the center of the top of the lifting plate 2, a receiving box 4 slidably connected to the top of the conveying rod 3, a heat preservation box 5 installed on the side wall of the conveying rod 3 near the receiving box 4, a feeding pump 6 installed at the top end of the mounting plate 1 near the lifting plate 2, a bottom end of the conveying rod 3 fixedly connected to the top of the lifting plate 2, and a fixing block 7 fixedly connected to the bottom end of the conveying rod 3 near the lifting plate 2, and an electric heating rod 401 installed inside the receiving box 4 at the end away from the heat preservation box 5. A heat-conducting pipe 402 is installed inside the heat-insulating box 5; a conveying pump 501 is fixedly connected to the top of the inside of the heat-insulating box 5, and the conveying pump 501 is connected to the bottom of the receiving box 4. A heat-insulating cylinder 502 is fixedly connected to the bottom of the conveying pump 501. When the drive motor 202 is started, the rotation motor 303 is also started, so that the lifting plate 2 can change its height. The rotation motor 303 drives the threaded rod 301 to rotate, so that the sliding block 302 can move along the side groove of the conveying rod 3. The heat-insulating box 5 drives the bottom extrusion head 503 to move to the corresponding position. The conveying pump 501 first conveys the material into the heat-insulating cylinder 502 and then extrudes it through the extrusion head 503.

[0027] The material inside the container 4 is heated by activating the electric heating rod 401 to prevent cooling and solidification. At the same time, when conveying to the bottom extrusion head 503, it can be directly conveyed to the insulation cylinder 502 through the conveying pump 501 at the bottom of the container 4, reducing the conveying distance and preventing heat loss. The top outer wall of the heat conduction pipe 402 is connected to the inside of the container 4, so that the heat can be effectively transferred from the temperature inside the container 4 to the insulation cylinder 5, further preventing the temperature from dropping.

[0028] like Figure 1 , Figure 2As shown, both ends of the lifting plate 2 are threaded with lead screws 201. The bottom of the lead screw 201 passes through the interior of the mounting plate 1 and is connected to a drive motor 202. The inside of the conveying rod 3 is provided with a groove on the side near the insulation box 5, and a threaded rod 301 is provided through the groove. The outer wall of the threaded rod 301 is threaded with a sliding block 302. The sliding block 302 is slidably connected to the groove of the conveying rod 3. One end of the threaded rod 301 passes through the interior of the conveying rod 3 and is connected to a rotary motor 303, which can easily start the drive motor 202, thereby driving the lead screw 201 to rotate, so that the lifting plate 2 can change height. Then, the lifting plate 2 drives the conveying rod 3 to move up and down. At the same time, the rotary motor 303 is started, and the rotary motor 303 drives the threaded rod 301 to rotate, so that the sliding block 302 can move along the side groove of the conveying rod 3, thereby driving the insulation box 5 to move.

[0029] like Figure 1 , Figure 3 As shown, the interior of the container 4 is hollow, and a feeding conduit 601 is provided on one side of the container 4. The interior of the feeding pump 6 is connected to the container 4 through the feeding conduit 601. The length of the feeding conduit 601 is greater than the distance between the feeding pump 6 and the end of the conveying rod 3 away from the lifting plate 2. The feeding conduit 601 can be a flexible hose. When the container 4 moves left and right on the conveying rod 3, the end of the feeding conduit 601 connected to the container 4 can also move with the container 4. The top of the heat pipe 402 is arc-shaped and penetrates the interior of the container 4. Both ends of the heat pipe 402 are connected to the interior of the insulation box 5. The diameter of the insulation cylinder 502 is smaller than the inner diameter of the insulation box 5. The feed pump 6 can easily transport the corresponding material into the container 4 first, and then heat the material inside the container 4 by activating the electric heating rod 401 to avoid cooling and solidification. At the same time, since the top outer wall of the heat pipe 402 is connected to the interior of the container 4, heat can be effectively transferred from the temperature inside the container 4 to the insulation box 5, thereby heating the outer wall of the insulation cylinder 502 and further preventing the temperature from dropping.

[0030] like Figure 4 , Figure 5 As shown, a receiving groove 701 is provided at the top of the fixed block 7 near the receiving box 4, and an electric heating wire is provided inside the receiving groove 701 in an arc shape. The bottom end of the heat preservation cylinder 502 passes through the inside of the heat preservation box 5 and is connected to the extrusion head 503. The diameter of the receiving groove 701 is larger than the outer wall diameter of the extrusion head 503. Even if the extrusion head 503 becomes solidified, the heat preservation box 5 can be moved to the top of the fixed block 7, so that the extrusion head 503 can be moved into the receiving groove 701. The electric heating wire inside the receiving groove 701 heats the extrusion head 503, which can effectively melt the material again and remove the solidification and blockage of the material.

[0031] In use, the drive motor 202 can be easily started, which in turn drives the lead screw 201 to rotate, thereby changing the height of the lifting plate 2. The lifting plate 2 then drives the conveyor rod 3 to move up and down. At the same time, the rotary motor 303 is started, which drives the threaded rod 301 to rotate, thereby allowing the sliding block 302 to move along the side groove of the conveyor rod 3, which in turn moves the insulation box 5. The insulation box 5 moves the bottom extrusion head 503 to the corresponding position. The conveying pump 501 is then started, which can transport the material inside the top receiving box 4 to the bottom insulation cylinder 502. Finally, the material is extruded through the extrusion head 503 at the bottom of the insulation cylinder 502, thus completing the dispensing operation. In use, the dispensing position and height can be effectively adjusted, making it convenient to operate in different positions. Since the conveying pump 501 first transports the material to the insulation cylinder 502 and then extrudes it through the extrusion head 503, the insulation cylinder 502 can store and mix the material, effectively maintaining the continuity and uniformity of the extrusion.

[0032] During use, the feed pump 6 can conveniently transport the corresponding material to the receiving box 4 first, and then heat the material inside the receiving box 4 by activating the electric heating rod 401 to prevent cooling and solidification. At the same time, when conveying to the bottom extruder 503, it can be directly conveyed to the insulation cylinder 502 through the conveying pump 501 at the bottom of the receiving box 4, reducing the conveying distance and preventing temperature loss. Since the top outer wall of the heat conduction pipe 402 is connected to the inside of the receiving box 4, it can effectively transfer heat from the temperature inside the receiving box 4 to the insulation box 5, thereby heating the outer wall of the insulation cylinder 502 and further preventing temperature drop. Even if the extruder 503 solidifies, the insulation box 5 can be moved to the top of the fixing block 7, so that the extruder 503 moves to the receiving groove 701. The electric heating wire inside the receiving groove 701 heats the extruder 503, which can effectively melt the material again and clear the solidification and blockage of the material.

[0033] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
