Description

Technical Field

[0001] This utility model relates to the field of dispensing equipment technology, specifically to a hot dispensing device for dispensing machines. Background Technology

[0002] A dispensing machine is an automated machine specifically designed to control fluids and dispense, coat, or encapsulate liquids onto the surface or interior of a product. It is primarily used for the precise application, filling, injection, coating, or dripping of adhesives, oils, paints, and other liquids to specific locations on each product during manufacturing processes. Utilizing compressed air as a power source, it forces the adhesive into a feed pipe connected to a piston chamber. The flow of adhesive is controlled by the up-and-down movement of the piston. The amount of adhesive dispensed is determined by the downward distance of the piston, which can be adjusted manually or precisely controlled through programming. The dispensing machine requires a supply hose to transport the adhesive.

[0003] CN215997340U discloses a glue supply device for a dispensing machine, comprising a glue supply cylinder loaded with glue, a glue supply pipe connected to the glue supply cylinder, and a glue supply plate for mounting the glue supply pipe. The glue supply pipe branches into several glue supply sub-pipes, which are mounted on the glue supply plate with their openings facing a template between two scrapers. A glue supply drive is installed on the glue supply pipe to drive the glue from the glue supply cylinder along the glue supply pipe and the glue supply sub-pipes to the template. This application has a glue supply drive that continuously discharges glue from the glue supply cylinder along the glue supply pipe to the template of the dispensing machine, ensuring that there is always a sufficient amount of glue on the template for dispensing workpieces. This reduces the frequency of operators checking the glue level on the template and improves the continuous dispensing effect of the dispensing machine.

[0004] While existing adhesive supply hoses offer numerous advantages during use, they still suffer from several drawbacks. Their insulation of the adhesive is insufficient, leading to heat loss during delivery within the hose due to its thermal conductivity. This affects the adhesive's flowability and consequently, the quality of subsequent dispensing. Utility Model Content

[0005] To address the problems in the prior art, this utility model provides a hot dispensing device for adhesive liquid in a dispensing machine.

[0006] The technical solution adopted by this utility model to solve its technical problem is a hot dispensing device for glue dispensing machine, including an outer tube, a glue dispensing tube and a distribution tube. The glue dispensing tube is arranged inside the outer tube, and a distribution tube with a circular array is welded to the upper outer side of the outer tube. A blade with a circular array is bonded and fixed to the outer wall of the glue dispensing tube.

[0007] By adopting the above technical solution, the glue delivery pipe is located inside the outer sleeve, forming a pipe-in-pipe structure. The external hot water pump can pump the heat medium, allowing the heat medium to flow from top to bottom through the gap between the glue delivery pipe and the outer sleeve via the distribution pipe. The heat medium directly contacts the outer wall of the glue delivery pipe, enabling heat conduction and thus keeping the glue liquid inside the glue delivery pipe warm. The heat-conducting fins further assist in heat conduction, ensuring the heat preservation effect of the glue liquid, preventing heat loss, ensuring the fluidity of the glue liquid, and guaranteeing the smoothness of glue delivery. The heat medium directly impacts the blades, driving the glue delivery pipe to rotate circumferentially inside the outer sleeve. Following the rotation of the heat-conducting fins, the glue liquid inside the glue delivery pipe is dispersed, causing the glue liquid gathered in the middle of the glue delivery pipe to scatter, ensuring uniform heat conduction and further guaranteeing the smoothness of glue delivery.

[0008] Specifically, the outer sleeve has first support bearings interference-fitted on both the upper and lower sides of its inner wall, and the glue delivery tube is interference-fitted on the inner ring of the first support bearings. The glue delivery tube is rotatably connected to the outer sleeve through the first support bearings.

[0009] By adopting the above technical solution, the first support bearing can support the rubber delivery tube, ensuring the stability of the rotational position of the rubber delivery tube inside the outer sleeve, and reducing frictional loss during relative movement.

[0010] Specifically, a first sealing ring is bonded and fixed to both sides of the inner wall of the outer sleeve, and the inner ring of the first sealing ring is in contact with the outer ring of the glue delivery tube.

[0011] By adopting the above technical solution, the first sealing ring can seal the gap between the outer sleeve and the glue delivery pipe, ensuring the flow sealing of the heat medium between the outer sleeve and the glue delivery pipe, ensuring heat exchange efficiency, and preventing heat medium leakage from contaminating the first support bearing.

[0012] Specifically, the inner wall of the glue delivery tube is fitted with second support bearings on both the upper and lower sides, and the inner ring of the second support bearing is fitted with a pipe joint. The inner wall of the glue delivery tube is bonded and fixed with second sealing rings on both sides, and the inner ring of the second sealing ring is in contact with the outer wall of the pipe joint. The two second sealing rings are located between the second bearings.

[0013] By adopting the above technical solution, the two pipe joints are connected to the adhesive pump and the dispensing tube respectively, thereby ensuring the stability of the adhesive delivery trajectory through the adhesive delivery tube. The second support bearing supports the relative position between the adhesive delivery tube and the pipe joint, ensuring the stability of the relative position between the pipe joint and the adhesive delivery tube, avoiding the influence of the rotation of the adhesive delivery tube on the pipe joint, and ensuring the normal use of the adhesive pump and the dispensing tube. The second sealing ring seals the adhesive delivery tube and the pipe joint to prevent adhesive leakage and ensure the purity of the adhesive.

[0014] Specifically, an inlet pipe is provided on the outside of the outer sleeve, and the diverter pipe is connected to the inlet pipe. The diverter pipe is located inside the outer sleeve and is designed in a bent shape.

[0015] By adopting the above technical solution, the inlet pipe can be connected to the pipeline of the hot water pump. Thus, the hot medium can be evenly distributed to the inside of the outer casing through the inlet pipe and the circular array of distribution pipes, avoiding local medium accumulation. Furthermore, the bending shape of the distribution pipe allows the hot medium inside the distribution pipe to be sprayed vertically, so that the hot medium directly impacts the blades. Thus, the flow rate of the hot medium can drive the rubber delivery pipe to rotate.

[0016] Specifically, the outer wall of the glue delivery tube is integrally formed with heat-conducting fins, and the heat-conducting fins adopt a spiral shape design.

[0017] By adopting the above technical solution, the spiral heat-conducting fins are integrally formed on the outer wall of the glue delivery pipe, increasing the contact area between the glue and the heating medium. One part of the heat-conducting fins is located between the outer sleeve and the glue delivery pipe, and the other part is located inside the glue delivery pipe. Thus, the spiral structure can guide the heating medium to flow along the fins, extend the heat exchange path, and ensure heat transfer efficiency. Moreover, the rotating heat-conducting fins can drive and disperse the glue, preventing the glue from accumulating in the middle of the glue delivery pipe and ensuring the uniformity of heat preservation of the glue.

[0018] Specifically, a drain pipe is welded to one side of the lower end of the outer wall of the glue delivery tube, and the drain pipe is connected to the inside of the outer sleeve.

[0019] By adopting the above technical solution, the drain pipe is directly connected to the inside of the outer casing and can be used to discharge the heating medium after use.

[0020] The beneficial effects of this utility model are:

[0021] The adhesive heat transfer device for a dispensing machine described in this utility model can keep the adhesive inside the dispensing tube warm, and further ensure the heat preservation effect of the adhesive by using heat-conducting fins to prevent heat loss of the adhesive, ensure the fluidity of the adhesive, and guarantee the smooth dispensing of the adhesive.

[0022] The adhesive hot conveying device for a dispensing machine described in this utility model can disperse the adhesive inside the dispensing tube, causing the adhesive that has gathered in the middle of the dispensing tube to spread out, ensuring uniform heat conduction of the adhesive, and further ensuring the smooth dispensing of the adhesive.

[0030] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0031] To save manpower and improve efficiency, as one embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the adhesive hot transfer device for a dispensing machine of the present invention includes an outer tube 1, an adhesive transfer tube 2 and a diversion tube 13. The adhesive transfer tube 2 is arranged inside the outer tube 1. A diversion tube 13 arranged in a circular array is welded to the upper outer side of the outer tube 1. A blade 24 arranged in a circular array is bonded and fixed to the outer wall of the adhesive transfer tube 2.

[0032] In use, the glue delivery pipe 2 is located inside the outer casing 1, forming a pipe-within-a-pipe structure. The external hot water pump can pump the heat medium, allowing the heat medium to flow from top to bottom through the distribution pipe 13 in the gap between the glue delivery pipe 2 and the outer casing 1. The heat medium directly contacts the outer wall of the glue delivery pipe 2, enabling heat conduction and thus keeping the glue liquid inside the glue delivery pipe 2 warm. The heat-conducting fins 25 further assist in heat conduction, ensuring the heat preservation effect of the glue liquid, preventing heat loss, ensuring the fluidity of the glue liquid, and guaranteeing the smoothness of glue delivery. The heat medium directly impacts the blades 24, causing the glue delivery pipe 2 to rotate circumferentially inside the outer casing 1. With the following rotation of the heat-conducting fins 25, the glue liquid inside the glue delivery pipe 2 can be dispersed, causing the glue liquid gathered in the middle of the glue delivery pipe 2 to spread out, ensuring uniform heat conduction and further guaranteeing the smoothness of glue delivery.

[0033] To maintain rotational stability, for example, such as Figure 2 As shown, the outer sleeve 1 has a first support bearing 14 with an interference fit on both the upper and lower sides of its inner wall. The glue delivery tube 2 is interference fitted on the inner ring of the first support bearing 14. The glue delivery tube 2 is rotatably connected to the outer sleeve 1 through the first support bearing 14.

[0034] In use, the first support bearing 14 can support the glue delivery tube 2, ensuring the stability of the rotational position of the glue delivery tube 2 inside the outer sleeve 1, and reducing frictional loss during relative movement.

[0035] For sealing purposes, exemplarily, such as Figure 4 As shown, a first sealing ring 15 is bonded and fixed to both sides of the inner wall of the outer sleeve 1, and the inner ring of the first sealing ring 15 is in contact with the outer ring of the glue delivery tube 2.

[0036] During use, the first sealing ring 15 can seal the gap between the outer sleeve 1 and the glue delivery pipe 2, ensuring the flow sealing of the heat medium between the outer sleeve 1 and the glue delivery pipe 2, ensuring heat exchange efficiency, and preventing heat medium leakage from contaminating the first support bearing 14.

[0037] For rotational stability, for example, such as Figure 2 As shown, the inner walls of the glue delivery tube 2 are fitted with second support bearings 22 on both the upper and lower sides. The inner ring of the second support bearing 22 is fitted with a pipe joint 21. The inner walls of the glue delivery tube 2 are bonded and fixed with second sealing rings 23 on both sides. The inner ring of the second sealing ring 23 is in contact with the outer wall of the pipe joint 21. The two second sealing rings 23 are located between the second bearings.

[0038] In use, the two pipe joints 21 are connected to the glue pump and the dispensing tube respectively, thereby ensuring the stability of the glue delivery trajectory through the glue delivery tube 2. The second support bearing 22 supports the relative position between the glue delivery tube 2 and the pipe joint 21, ensuring the stability of the relative position between the pipe joint 21 and the glue delivery tube 2, and preventing the rotation of the glue delivery tube 2 from affecting the pipe joint 21, thus ensuring the normal use of the glue pump and the dispensing tube. The second sealing ring 23 seals the glue delivery tube 2 and the pipe joint 21 to prevent glue leakage and ensure the purity of the glue.

[0039] For the input of the heat medium, for example, such as Figure 4 As shown, an inlet pipe 11 is provided on the outside of the outer sleeve 1, and a diversion pipe 13 is connected to the inlet pipe 11. The diversion pipe 13 is located inside the outer sleeve 1 and is designed in a bent shape.

[0040] In use, the inlet pipe 11 can be connected to the pipeline of the hot water pump, so that the hot medium can be evenly distributed to the inside of the outer casing 1 through the inlet pipe 11 and the circular array of diverter pipes 13, avoiding local medium accumulation. The bending shape of the diverter pipe 13 allows the hot medium inside the diverter pipe 13 to be sprayed out vertically, so that the hot medium directly impacts the blades 24, thereby driving the glue delivery pipe 2 to rotate through the flow rate of the hot medium.

[0041] For heat conduction, for example, such as Figure 3 As shown, the outer wall of the glue delivery tube 2 is integrally formed with heat-conducting fins 25, which are designed in a spiral shape.

[0042] During use, the spiral heat-conducting fins 25 are integrally formed on the outer wall of the glue delivery pipe 2, increasing the contact area between the glue and the heating medium. Part of the heat-conducting fins 25 is located between the outer sleeve 1 and the glue delivery pipe 2, and the other part is located inside the glue delivery pipe 2. Thus, the spiral structure can guide the heating medium to flow along the fins, extend the heat exchange path, and ensure heat transfer efficiency. Moreover, the heat-conducting fins 25 can drive and disperse the glue during rotation, preventing the glue from accumulating in the middle of the glue delivery pipe 2 and ensuring the uniformity of heat preservation of the glue.

[0043] For the removal of the heat medium, exemplarily, such as Figure 1 As shown, a drain pipe 12 is welded to one side of the lower end of the outer wall of the glue delivery tube 2, and the drain pipe 12 is connected to the inside of the outer sleeve tube 1.

[0044] During use, the drain pipe 12 is directly connected to the inside of the outer sleeve 1 and can be used to drain the heating medium after use.

[0045] In use, the two pipe joints 21 on the inner wall of the glue delivery pipe 2 are connected to the glue pump and the glue dispensing pipe respectively to form a glue delivery channel, and the liquid inlet pipe 11 of the outer sleeve 1 is connected to the hot water pump to form a heat medium supply channel.

[0046] When the hot water pump is started, the hot medium enters the circular array of distribution pipes 13 through the inlet pipe 11. The distribution pipes 13 evenly distribute the hot medium and spray it vertically into the gap between the outer sleeve 1 and the glue delivery pipe 2. The hot medium flows from top to bottom in the gap and is heat-conducted through the outer wall of the glue delivery pipe 2 and the heat-conducting fins 25 to keep the glue delivery pipe 2 warm.

[0047] When the glue pump is started, the glue enters the glue delivery tube 2 through the pipe joint 21. The heat medium continuously contacts the outer wall of the glue delivery tube 2 and keeps the glue inside warm through heat conduction. When the heat medium is sprayed out, it directly impacts the circular array blades 24 on the outer wall of the glue delivery tube 2, generating a rotational driving force. The glue delivery tube 2 rotates stably in the outer tube 1 through the first support bearing 14. The rotation of the glue delivery tube 2 drives the internal spiral heat-conducting fins 25 to rotate synchronously, stirring and dispersing the glue. The rotating heat-conducting fins 25 disperse the glue that gathers in the middle of the glue delivery tube 2, ensuring that the glue is heated evenly.

[0048] The heat medium that has completed the heat exchange is discharged through the drain pipe 12 at the lower end of the glue delivery pipe 2.
