Description

Technical Field

[0001] This utility model relates to the field of dispensing machine technology, specifically to a dispensing machine that avoids solidification and blockage of the dispensing nozzle. Background Technology

[0002] A dispensing machine, also known as a glue applicator, glue dripper, glue applicator, or glue potting machine, is an automated machine specifically designed for controlling fluids. It dispenses and coats fluids onto the surface or interior of a product, enabling three-dimensional or four-dimensional dispensing with precise positioning, accurate glue control, and preventing stringing, leakage, or dripping.

[0003] For example, application number 202121610281.4 discloses a dispensing machine, including a housing, an inlet valve assembly, and an outlet valve. The housing has an adhesive storage chamber inside, and the inlet valve assembly and outlet valve are respectively disposed on the side wall of the housing. The outlet port of the inlet valve assembly and the inlet port of the outlet valve are respectively connected to the adhesive storage chamber. The dispensing machine provided by this utility model includes an adhesive back-suction structure formed by the dispensing valve stem and the control chamber. The dispensing valve stem moves up and down to change the volume of the dispensing valve cavity and create negative pressure. This effectively draws back the residual adhesive inside the dispensing tube to the outlet valve at the moment when the dispensing machine stops dispensing, thus effectively avoiding the phenomenon of dripping or stringing.

[0004] However, while this dispensing machine can draw back the glue from the dispensing valve, it is not very convenient to scrape off residual glue at the dispensing nozzle, nor is it convenient to adjust the size of the dispensing nozzle. This results in excessive glue being dispensed when only a small amount of glue is needed, causing glue to accumulate at the dispensing nozzle and leading to blockage. Even when the dispensing machine is not in use, residual glue remains at the dispensing nozzle, causing blockage. Furthermore, the machine is not very effective at simultaneously cleaning residual glue at the dispensing nozzle, which reduces the lifespan of the dispensing machine.

[0005] Therefore, in view of this, we have studied and improved the existing structure to propose a dispensing machine that avoids solidification and clogging of the dispensing nozzle. Utility Model Content

[0006] The purpose of this invention is to provide a dispensing machine that avoids solidification and blockage of the dispensing nozzle, thereby solving the problems mentioned in the background art, such as the low ease of scraping off residual glue at the dispensing nozzle and the low ease of adjusting the size of the dispensing nozzle.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a dispensing machine that avoids solidification and blockage of the dispensing nozzle, comprising a dispensing machine body, a slider, and an adjustment mechanism disposed on the outer wall of the slider, wherein the adjustment mechanism includes a sliding component;

[0008] The sliding assembly includes an adjusting threaded rod and an adjusting plate. A connecting frame is slidably connected to the outer wall of the dispensing machine body. A slider is slidably connected to the outer wall of the connecting frame. A placement bucket is provided above the slider. A connecting pipe is fixedly connected to the outer wall of the placement bucket. A glue outlet valve located below the slider is fixedly connected to one end of the connecting pipe. A micro servo motor is fixedly connected to the outer wall of the slider. An adjusting threaded rod that is rotatably connected to the outer wall of the slider is fixedly connected to the output end of the micro servo motor. An adjusting plate that is slidably connected to the outer wall of the slider is threadedly connected to the outer wall of the adjusting threaded rod.

[0009] Furthermore, a heating sleeve is fitted onto the outer wall of the connecting tube, a heating wire is provided inside the heating sleeve, a fixing hook and loop fastener is fixedly connected to one end of the heating sleeve, and a connecting hook and loop fastener is fixedly connected to the other end of the heating sleeve.

[0010] Furthermore, a vertical servo motor is fixedly connected to the outer wall of the dispensing machine body, and a vertical threaded rod that is rotatably connected to the output end of the vertical servo motor is fixedly connected to the outer wall of the dispensing machine body. The vertical threaded rod and the connecting frame are connected by threads, and a limit groove is provided at the connection part between the outer wall of the dispensing machine body and the connecting frame.

[0011] Furthermore, a transverse servo motor is fixedly connected to the outer wall of the connecting frame, and a transverse threaded rod that is rotatably connected to the output end of the transverse servo motor is fixedly connected to the outer wall of the connecting frame. The transverse threaded rod and the slider are connected by a thread, and a groove is provided at the connection between the outer wall of the connecting frame and the slider.

[0012] Furthermore, the adjusting threaded rod is provided in two sets, and the two sets of adjusting threaded rods rotate in opposite directions.

[0013] Furthermore, an adjustment groove is provided at the connection between the outer wall of the slider and the adjustment plate. Two sets of adjustment plates are provided, and the positions of the two sets of adjustment plates are symmetrical about the central axis of the dispensing valve.

[0014] Furthermore, the adjusting plate and the glue dispensing valve are fitted together, and the outer wall contour of the adjusting plate is larger than the outer wall contour of the glue outlet.

[0015] Furthermore, the fixing hook and loop fasteners are adhesively connected to each other.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This utility model, through the setting of the adjustment plate, improves the convenience of adjusting the size of the glue outlet when dispensing glue through a dispensing machine, and prevents excessive glue output from accumulating at the outlet and causing blockage. As needed, the micro servo motor can be turned on to rotate the threaded rod, driving the adjustment plate to slide along the outer wall of the adjustment groove, thereby adjusting the size of the glue outlet. This achieves the control operation that improves the anti-blocking effect of the glue outlet of the dispensing machine when dispensing glue.

[0018] 2. This utility model, through the setting of the adjustment plate, improves the scraping effect of residual glue on the surface of the glue outlet and prevents blockage of the glue outlet when the glue dispensing machine is not needed. The micro servo motor can be turned on to drive the adjustment plate to slide along the outer wall of the adjustment groove by adjusting the rotation of the threaded rod. The sliding of the adjustment plate scrapes the residual glue on the surface of the glue outlet, realizing the control operation to avoid the glue outlet of the glue dispensing machine from solidifying and blocking when the glue dispensing machine is not needed.

[0019] 3. This utility model, through the setting of the heating sleeve, prevents the glue from solidifying and causing blockage at the dispensing nozzle when dispensing glue with a dispensing machine. By fixing the hook and loop fasteners and connecting the hook and loop fasteners to the mutual adhesion, the heating sleeve is attached to the connecting pipes at various points. The heating wire keeps the glue in a watery state, preventing the glue from solidifying. This achieves improved control of the dispensing nozzle's unobstructed flow when the dispensing machine is not needed. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1

[0027] like Figures 1-3 As shown, a dispensing machine that avoids solidification and clogging of the dispensing nozzle includes a dispensing machine body 1, a slider 12, and an adjustment mechanism disposed on the outer wall of the slider 12. The adjustment mechanism includes a sliding component.

[0028] The sliding assembly includes an adjusting threaded rod 21 and an adjusting plate 22. A connecting frame 11 is slidably connected to the outer wall of the dispensing machine body 1. A slider 12 is slidably connected to the outer wall of the connecting frame 11. A placement bucket 13 is provided above the slider 12. A connecting pipe 14 is fixedly connected to the outer wall of the placement bucket 13. One end of the connecting pipe 14 is fixedly connected to a glue outlet valve 15 located below the slider 12. A glue outlet 16 is provided below the glue outlet valve 15. A micro servo motor 2 is fixedly connected to the outer wall of the slider 12. An adjusting threaded rod 21 that is rotatably connected to the outer wall of the slider 12 is fixedly connected to the output end of the micro servo motor 2. An adjusting plate 22 that is slidably connected to the outer wall of the slider 12 is threadedly connected to the outer wall of the adjusting threaded rod 21.

[0029] Furthermore, a vertical servo motor 111 is fixedly connected to the outer wall of the dispensing machine body 1. The output end of the vertical servo motor 111 is fixedly connected to a vertical threaded rod 112 that is rotatably connected to the outer wall of the dispensing machine body 1. The vertical threaded rod 112 and the connecting frame 11 are connected by a thread. A limiting groove 113 is provided at the connection between the outer wall of the dispensing machine body 1 and the connecting frame 11. The connecting frame 11 forms a sliding structure through the vertical threaded rod 112 and the limiting groove 113, which is conducive to the rotation of the vertical threaded rod 112 driving the connecting frame 11 to slide along the outer wall of the limiting groove 113, thereby realizing the vertical adjustment control operation of the glue output port 16.

[0030] Furthermore, a horizontal servo motor 121 is fixedly connected to the outer wall of the connecting frame 11. The output end of the horizontal servo motor 121 is fixedly connected to a horizontal threaded rod 122 that is rotatably connected to the outer wall of the connecting frame 11. The horizontal threaded rod 122 and the slider 12 are threadedly connected. A groove 123 is provided at the connection between the outer wall of the connecting frame 11 and the slider 12. The slider 12 forms a sliding structure through the horizontal threaded rod 122 and the groove 123, which facilitates the rotation of the horizontal threaded rod 122 to drive the slider 12 to slide along the outer wall of the groove 123, thereby realizing the horizontal adjustment control operation of the glue outlet 16.

[0031] Furthermore, there are two sets of adjusting threaded rods 21, and the two sets of adjusting threaded rods 21 rotate in opposite directions. This arrangement of the two sets of adjusting threaded rods 21 rotating in opposite directions allows for the control operation of the two sets of adjusting plates 22 sliding in opposite directions.

[0032] Furthermore, an adjustment groove 23 is provided at the connection between the outer wall of the slider 12 and the adjustment plate 22. Two sets of adjustment plates 22 are provided, and the positions of the two sets of adjustment plates 22 are symmetrical about the central axis of the glue dispensing valve 15. The adjustment plate 22 forms a sliding structure with the adjustment threaded rod 21 and the adjustment groove 23, which is conducive to the rotation of the adjustment threaded rod 21 driving the adjustment plate 22 to slide along the outer wall of the adjustment groove 23, thereby realizing the control operation of adjusting the size of the glue outlet 16.

[0033] Furthermore, the adjusting plate 22 is fitted together with the glue dispensing valve 15, and the outer contour of the adjusting plate 22 is larger than the outer contour of the glue outlet 16. This facilitates the control operation of scraping off residual glue on the surface of the glue outlet 16 by fitting the adjusting plate 22 and the glue dispensing valve 15 together.

[0034] Example 2

[0035] like Figure 1 , Figure 2 and Figure 4 As shown, this utility model proposes a dispensing machine that avoids glue outlet solidification and blockage. Compared with Embodiment 1, as another implementation of this utility model, a heating sleeve 3 is sleeved on the outer wall of the connecting tube 14. A heating wire 31 is provided inside the heating sleeve 3. One end of the heating sleeve 3 is fixedly connected to a fixing hook and loop fastener 32, and the other end of the heating sleeve 3 is fixedly connected to a connecting hook and loop fastener 33. By setting the heating sleeve 3, it is beneficial to prevent the glue from solidifying and causing blockage when dispensing glue. The fixing hook and loop fastener 32 and the connecting hook and loop fastener 33 are mutually adhered, so that the heating sleeve 3 is sleeved on the connecting tube 14 at each point. Through the heating of the heating wire 31, the glue is kept in a watery state, preventing the glue from solidifying. This realizes the control operation of improving the smoothness of the glue outlet of the dispensing machine when dispensing is not required.

[0036] Furthermore, the fixing hook and loop fastener 32 and the connecting hook and loop fastener 33 are mutually bonded. The heating sleeve 3 forms an installation structure with the connecting tube 14 through the fixing hook and loop fastener 32 and the connecting hook and loop fastener 33. This arrangement facilitates the heating sleeve 3 to be fitted onto the connecting tube 14 at various points, thereby preventing the glue outlet of the dispensing machine from solidifying and clogging.

[0037] Working principle: When using this dispensing machine that prevents glue outlet from solidifying and clogging, firstly, when dispensing glue through the dispensing machine, in order to improve the convenience of adjusting the size of the glue output port 16 and prevent excessive glue output from accumulating at the glue outlet and causing blockage, the micro servo motor 2 can be turned on as needed. By adjusting the rotation of the threaded rod 21, the adjusting plate 22 is driven to slide along the outer wall of the adjusting groove 23, thereby adjusting the size of the glue output port 16. This achieves the control operation that improves the anti-clogging effect of the glue output port 16 when dispensing glue through the dispensing machine.

[0038] Secondly, when the dispensing machine is not needed for dispensing, in order to improve the scraping effect of residual glue on the surface of glue outlet 16 and prevent the outlet from becoming blocked, the micro servo motor 2 can be turned on and the adjustment plate 22 can be driven to slide along the outer wall of the adjustment groove 23 by adjusting the rotation of the threaded rod 21. The sliding of the adjustment plate 22 scrapes the residual glue on the surface of glue outlet 16, thus achieving the control operation of avoiding solidification and blockage of the glue outlet when the dispensing machine is not needed.

[0039] Finally, when dispensing glue using the dispensing machine, in order to prevent the glue from solidifying at the dispensing nozzle and causing blockage, the fasteners 32 and 33 can be bonded together to allow the heating sleeve 3 to be fitted onto the connecting pipes 14 at various points. The heating wire 31 then heats the glue, keeping it in a liquid state and preventing it from solidifying. This improves the unobstructed flow of the dispensing nozzle when the dispensing machine is not needed.

[0040] This is the working principle of a dispensing machine that avoids the glue nozzle from solidifying and clogging.

Many modifications and variations will be apparent to those skilled in the art.
