Description

Technical Field

[0001] This utility model relates to the technical field of feeding devices, and in particular to a feeding device for a glue dispensing machine. Background Technology

[0002] A dispensing machine, also known as an AB two-component glue dispensing machine, is an automated machine that controls fluids and dispenses, coats, and seals liquids onto the surface or inside of a product. Before mixing different raw material glues and injecting them into the dispensing machine, the mixed raw material glues need to be stirred to ensure uniform mixing or to avoid the generation of air bubbles.

[0003] Chinese utility model patent CN217940030U discloses an automatic mixing and feeding device for a dispensing machine, including an automatic dispensing and feeding box and a feeding backup mechanism. A mixing box mechanism is installed at the top of the automatic dispensing and feeding box, and a feeding and packaging frame is provided in the middle of the automatic dispensing and feeding box. A limiting plate is installed inside the feeding and packaging frame, and a mixing conveying mechanism is installed at the front end of the feeding and packaging frame. A conveying pipe is provided inside the mixing conveying mechanism, and a distributing frame is installed at the front end of the conveying pipe. A feeding branch pipe is installed at the front end of the distributing frame. The feeding backup mechanism is installed below the automatic dispensing and feeding box. With this automatic mixing and feeding device for a dispensing machine, when the conveying pipe is installed inside the feeding and packaging frame and the automatic dispensing and feeding box, the mixed raw materials enter the conveying pipe and the distributing frame and are mixed and fed through three sets of feeding branch pipes. This changes the single-pipe structure used in the automatic dispensing machine during the feeding process, facilitating the mixing and feeding of different raw materials.

[0004] The automatic mixing and feeding device of the aforementioned glue dispensing machine directly injects the mixed glue raw material into the glue dispensing machine during the feeding process. This feeding method increases the probability of uneven mixing of glue raw material and the generation of air bubbles. Utility Model Content

[0005] To solve the above problems, this utility model provides a feeding device for a glue dispensing machine.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a feeding device for a dispensing machine, comprising a feeding tank and a discharge pipe fixed and connected to the bottom of the feeding tank, wherein the feeding tank is provided with multiple feeding mechanisms for supplying adhesive raw materials thereto, a U-shaped frame is fixed to the top of the feeding tank, a stirring column rotatably connected to the horizontal section of the U-shaped frame is provided through the horizontal section of the U-shaped frame, the stirring column extends into the interior of the feeding tank and is rotatably connected to the feeding tank, stirring blades for stirring the mixed adhesive raw materials are fixed on the side wall of the feeding tank, a rotating component for driving the stirring column to rotate is provided on the feeding tank, and a heating component for heating the adhesive raw materials is provided on the stirring column.

[0007] By adopting the above technical solution, different adhesive raw materials are supplied to the upper tank through a feeding mechanism. Then, a rotating component drives the stirring column to rotate, causing the stirring blades fixed to the stirring column to rotate and stir the mixed adhesive raw materials inside the upper tank until the raw materials are completely mixed. Finally, the adhesive raw materials are discharged into the dispensing machine through a discharge pipe. By mixing the adhesive raw materials beforehand, the probability of uneven mixing and air bubble formation is reduced. During the mixing process, a heating component heats the adhesive raw materials, slowing down the hardening speed and increasing the mixing time.

[0008] Furthermore, each of the feeding mechanisms includes a feeding assembly, which includes a feeding tank fixed to the top of the feeding tank, an inlet pipe fixed and connected to the bottom of the feeding tank, a feeding pipe fixed and connected to the bottom of the feeding tank, and a sealing piston slidably disposed in the feeding tank. The feeding pipe extends into the feeding tank, and both the feeding pipe and the inlet pipe are equipped with solenoid valves. The feeding mechanism also includes a lifting assembly for driving the sealing piston to rise and fall.

[0009] By employing the above technical solution, the lifting assembly drives the sealing piston to descend, simultaneously opening the solenoid valve on the supply pipe and closing the solenoid valve on the feed pipe. This increases the internal pressure of the supply tank, causing the adhesive material in the supply tank to be discharged into the feed tank through the supply pipe until the sealing piston descends to the bottom of the supply tank and the lifting assembly closes. Similarly, the lifting assembly drives the sealing piston to rise, simultaneously closing the solenoid valve on the supply pipe and opening the solenoid valve on the feed pipe. The adhesive material enters the supply tank through the feed pipe until the sealing piston rises to the top of the supply tank and the lifting assembly closes, thus ensuring normal material feeding from the supply tank.

[0010] Furthermore, the rotating assembly includes mounting blocks fixed to the top of the feeding tank, the number of mounting blocks being equal to the number of feeding tanks, and their positions corresponding one-to-one. The rotating assembly also includes a worm gear rotatably mounted between two mounting blocks, a motor fixed to one of the mounting blocks and driving the worm gear to rotate, and a second worm wheel fixedly sleeved on the stirring column and meshing with the worm gear.

[0011] By adopting the above technical solution, after the motor works, it drives the worm to rotate, which causes the second worm wheel meshing with the worm, the stirring column fixed to the second worm wheel, and the stirring blade fixed to the stirring column to rotate, so as to carry out normal stirring of the glue raw materials.

[0012] Furthermore, the lifting assembly includes a threaded post fixed to the top of the sealing piston, the threaded post passing through the top of the feeding tank and slidingly engaged. The lifting assembly also includes an internally threaded sleeve rotatably mounted on the top of the feeding tank and threadedly connected to the threaded post, a first worm wheel fixedly sleeved on the internally threaded sleeve and meshing with the worm, and a guide rod fixed to the top of the sealing piston, the guide rod passing through the top of the feeding tank and slidingly engaged.

[0013] By adopting the above technical solution, during the rotation of the worm, both the first worm wheel meshing with the worm and the internal threaded sleeve fixed to the first worm wheel rotate. Since the first worm wheel meshes with the threaded column, the threaded column causes the sealing piston to descend, ensuring normal material discharge from the feed tank. Similarly, when the worm rotates in the opposite direction, both the first worm wheel and the internal threaded sleeve rotate in the opposite direction. At this time, the threaded column causes the sealing piston to rise, ensuring normal material supply to the feed tank.

[0014] Furthermore, the feeding tank is equipped with a filter assembly, which includes a sleeve fixed to the inner top wall of the feeding tank. The end of the feeding pipe away from the feeding tank is fixed to and communicates with the side wall of the sleeve. The stirring column passes through the sleeve. The filter assembly also includes an installation cylinder rotatably installed at the bottom of the sleeve, a filter cylinder inserted into the inner wall of the installation cylinder, and a connecting plate installed on the feeding tank and fixed to the filter cylinder. The stirring column passes through the bottom of the installation cylinder and is fixed. The stirring column passes through the bottom of the filter cylinder and is slidably engaged. The stirring column passes through the top of the connecting plate and is rotatably connected. The connecting plate and the stirring column are sealed by a rotating shaft seal. A discharge through hole is provided through the side wall of the installation cylinder.

[0015] By adopting the above technical solution, during the material discharge process of the feeding tank, the glue raw material in the feeding pipe will first enter the filter cartridge, then the filter cartridge will filter the glue raw material, and finally the clean glue raw material will pass through the installation cylinder and the discharge through hole and flow into the feeding tank. By filtering out large particulate impurities in the glue raw material, the purity of the glue raw material is improved.

[0016] Furthermore, the heating assembly includes a mounting plate fixed to a U-shaped frame, a heat-conducting rod fixed to the mounting plate, and an electric heat tracing cable spirally wound on the heat-conducting rod. The stirring column has an internal hollow structure, and the heat-conducting rod passes through the top of the stirring column and is rotatably connected.

[0017] By adopting the above technical solution, the electric heating tape is connected to the power supply and generates heat. The heat is transferred to the stirring column and stirring blades in sequence through the heat-conducting rod. The stirring blades stir and heat the raw material glue, thereby increasing the stirring time of the glue raw material.

[0018] Furthermore, the connecting plate extends through the top of the feeding tank and is threadedly connected, and two sets of auxiliary handles are fixed to the top of the connecting plate, which are symmetrically arranged about the axis of the feeding tank.

[0019] By adopting the above technical solution and setting the connecting plate, it is easy to remove the filter cartridge from the feeding tank and clean it.

[0020] In summary, the present invention has the following beneficial effects: In this application, by setting a stirring column, stirring blades, rotating components and heating components, the mixed raw material glue is stirred, which reduces the probability of uneven mixing of glue raw materials and the generation of air bubbles.

[0027] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0028] like Figure 1-5As shown in the illustration, this application discloses a feeding device for a dispensing machine, including a feeding tank 1, a feeding mechanism 5, a rotating assembly 6, a filtering assembly 7, and a heating assembly 8. A discharge pipe is fixed to and connected to the bottom of the feeding tank 1, and the discharge pipe is fixed to and connected to the feed pipe 512 of the dispensing machine. A U-shaped frame 2 is fixed to the top of the feeding tank 1, and a stirring column 3, rotatably connected to the horizontal section of the U-shaped frame 2, is provided through it. The stirring column 3 has a hollow internal structure. The stirring column 3 extends into the interior of the feeding tank 1 and is rotatably connected to the feeding tank 1. A stirring blade 4 for stirring the mixed adhesive raw materials is fixed to the side wall of the feeding tank 1.

[0029] Different adhesive raw materials are supplied to the feeding tank 1 by the feeding mechanism 5. Then, the rotating component 6 drives the stirring column 3 to rotate, causing the stirring blades 4, which are fixed to the stirring column 3, to rotate and stir the mixed adhesive raw materials inside the feeding tank 1 until the raw materials are completely mixed. Finally, the adhesive raw materials are discharged into the dispensing machine through the discharge pipe. By mixing the adhesive raw materials before mixing, the probability of uneven mixing and air bubble formation is reduced. During the mixing process, the heating component 8 heats the adhesive raw materials, which slows down the hardening speed of the adhesive raw materials and increases the mixing time.

[0030] A feeding mechanism 5 is installed on the feeding tank 1 and is used to supply adhesive raw materials to the feeding tank 1. Two sets of feeding mechanisms 5 are provided, each including a feeding assembly 51 and a lifting assembly 52. ​​The feeding assembly 51 includes a feeding tank 511, a feed pipe 512, a feeding pipe 513, and a sealing piston 514. The feeding tank 511 is fixed to the top of the feeding tank 1, and the feed pipe 512 is fixed to and connected to the bottom of the feeding tank 511. The feeding pipe 513 is fixed to and connected to the bottom of the feeding tank 511 and extends into the feeding tank 1. Both the feeding pipe 513 and the feed pipe 512 are equipped with solenoid valves, and the sealing piston 514 is slidably disposed within the feeding tank 511.

[0031] The lifting assembly 52 is used to drive the sealing piston 514 to rise and fall. The lifting assembly 52 includes a threaded post 521, an internal threaded sleeve 522, a first worm gear 523, and a guide rod 524. The threaded post 521 is fixed to the top of the sealing piston 514 and passes through the top of the feed tank 511 and is slidably engaged. The internal threaded sleeve 522 is rotatably mounted on the top of the feed tank 511 and is threadedly connected to the threaded post 521. The first worm gear 523 is fixedly sleeved on the internal threaded sleeve 522. The guide rod 524 is fixed to the top of the sealing piston 514 and passes through the top of the feed tank 511 and is slidably engaged.

[0032] During the rotation of the worm 62, the first worm wheel 523 meshing with the worm 62 and the internal threaded sleeve 522 fixed to the first worm wheel 523 both rotate. Since the first worm wheel 523 meshes with the threaded column 521, the threaded column 521 drives the sealing piston 514 to descend. At the same time, the solenoid valve on the feed pipe 513 is opened and the solenoid valve on the feed pipe 512 is closed. The internal pressure of the feed tank 511 increases, so that the glue material in the feed tank 511 is discharged into the loading tank 1 through the feed pipe 513 until the sealing piston 514 descends to the bottom of the feed tank 511 and closes the lifting assembly 52. Similarly, the worm gear 62 rotates in the opposite direction, causing the first worm wheel 523 and the internal threaded sleeve 522 to rotate in the opposite direction. At this time, the threaded column 521 drives the sealing piston 514 to rise, while closing the solenoid valve on the feed pipe 513 and opening the solenoid valve on the feed pipe 512. The glue raw material will enter the feed tank 511 through the feed pipe 512 until the sealing piston 514 rises to the top of the feed tank 511 and closes the lifting assembly 52, so as to ensure normal material supply to the feed tank 511.

[0033] A rotating assembly 6 is mounted on the feeding tank 1 and is used to drive the stirring column 3 to rotate. The rotating assembly 6 includes a mounting block 61, a worm gear 62, a motor 63, and a second worm wheel 64. The mounting blocks 61 are fixed to the top of the feeding tank 511, and the number of mounting blocks 61 is equal to the number of feeding tanks 511, with their positions corresponding one-to-one. The worm gear 62 is rotatably mounted between two mounting blocks 61, and the motor 63 is fixed to one of the mounting blocks 61 and drives the worm gear 62 to rotate. The second worm wheel 64 is fixedly sleeved on the stirring column 3 and meshes with the worm gear 62, while the first worm wheel 523 meshes with the worm gear 62.

[0034] After the motor 63 starts working, it drives the worm gear 62 to rotate, which causes the second worm wheel 64 meshing with the worm gear 62, the stirring column 3 fixed to the second worm wheel 64, and the stirring blade 4 fixed to the stirring column 3 to rotate, so as to carry out normal stirring of the glue raw materials.

[0035] A filter assembly 7 is mounted on the feeding tank 1 and includes a sleeve 71, a mounting cylinder 72, a filter cartridge 73, and a connecting plate 74. The sleeve 71 is fixed to the inner top wall of the feeding tank 1, and the end of the feed pipe 513 away from the feeding tank 511 is fixed to and communicates with the side wall of the sleeve 71. A stirring column 3 passes through the sleeve 71, and the mounting cylinder 72 is rotatably mounted on the bottom of the sleeve 71. A discharge through-hole 75 is provided through the side wall of the mounting cylinder 72. The stirring column 3 passes through the bottom of the mounting cylinder 72 and is fixed. The stirring column 3 also passes through the bottom of the filter cartridge 73 and is slidably fitted, with the filter cartridge 73 inserted into the inner wall of the mounting cylinder 72. The stirring column 3 also passes through the bottom of the filter cartridge 73 and is slidably fitted. The connecting plate 74 is mounted on the feeding tank 1 and fixed to the filter cartridge 73. The stirring column 3 passes through the top of the connecting plate 74 and is rotatably connected. A rotary shaft seal is provided between the connecting plate 74 and the stirring column 3 to maintain a seal. During the discharge process of the feeding tank 511, the glue material in the feeding pipe 513 will first enter the filter cartridge 73, then the filter cartridge 73 will filter the glue material, and finally the clean glue material will pass through the installation cylinder 72 and the discharge through hole 75 and flow into the feeding tank 1. By filtering out large particulate impurities in the glue material, the purity of the glue material is improved.

[0036] A heating assembly 8 is mounted on the stirring column 3 and is used to heat the adhesive raw material. The heating assembly 8 includes a mounting plate 81, a heat-conducting rod 82, and an electric heating tape 83. The mounting plate 81 is fixed to the U-shaped frame 2. The heat-conducting rod 82 is fixed to the mounting plate 81, passes through the top of the stirring column 3, and is rotatably connected. The electric heating tape 83 is spirally wound around the heat-conducting rod 82. In this embodiment, an insulating sleeve can be installed on the mounting plate 81 to cover the electric heating tape 83 and the upper end of the heat-conducting rod 82. The electric heating tape 83 is powered on and generates heat. The heat is transferred sequentially to the stirring column 3 and the stirring blades 4 through the heat-conducting rod 82. The stirring blades 4 stir and heat the raw adhesive, increasing the stirring time of the adhesive raw material.

[0037] The connecting plate 74 passes through the top of the feeding tank 1 and is threadedly connected. Two sets of auxiliary handles are fixed to the top of the connecting plate 74, which are symmetrically arranged about the axis of the feeding tank 1. The connecting plate 74 facilitates the removal and cleaning of the filter cartridge 73 from the feeding tank 1.
