[0001] This utility model relates to a glue dispensing device and belongs to the field of glue dispensing technology. Background Technology

[0002] Glue injection refers to injecting glue into a small space, allowing it to flow naturally and fill the gaps, thereby firmly fixing the object.

[0003] Some products require the use of a mixture of two or more adhesives during processing. However, existing dispensing equipment does not effectively separate the pipelines for different adhesives, which can lead to adhesive mixing at the dispensing port and causing blockage. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a dispensing device that can effectively separate multiple different adhesives, prevent adhesive cross-contamination, and prevent clogging of the dispensing port.

[0005] To achieve the aforementioned objectives, the technical solution adopted by this utility model includes:

[0006] A dispensing device includes a dispensing unit, comprising a cylinder base, a housing, a drive assembly, a nozzle connecting plate, and nozzles. The cylinder base houses at least two cylinders, each containing a piston rod disposed inside the cylinder. The piston rods are slidably connected to the cylinders, and their movement relative to the cylinders enables adhesive suction or discharge. The housing has at least two inlet channels, one end of which penetrates the housing to form an inlet. The end of the inlet channel furthest from the inlet corresponds to a position on a cylinder, allowing adhesive to enter the cylinder through the inlet channel. The drive assembly is connected to the end of the piston rod furthest from the cylinder, and the piston rod slides relative to the cylinder under the drive of the drive assembly to achieve adhesive suction and discharge. The nozzle connecting plate has at least two outlet holes, each corresponding to a position on a cylinder. The nozzles are disposed on the nozzle connecting plate, and adhesive from the outlet holes enters the nozzles. The nozzles are used to spray out the mixed adhesive.

[0007] Furthermore, the nozzle is equipped with a dispensing cylinder, and the dispensing cylinder is equipped with a stirrer. Different adhesives entering the dispensing cylinder are stirred evenly by the stirrer.

[0008] Furthermore, a first blocking element is provided on the glue inlet channel. The first blocking element is used to control the opening and closing of the glue inlet channel. When the glue is injected, the first blocking element blocks the glue inlet channel to prevent the glue from entering the cylinder.

[0009] Furthermore, a second blocking element is provided on the glue outlet hole. The second blocking element is used to control the opening and closing of the glue outlet hole. When the glue is sucked up, the second blocking element blocks the glue outlet hole to prevent glue from entering the glue outlet hole.

[0010] Furthermore, an inlet / outlet valve assembly is provided on one side of the housing, which is used to control the opening and closing of the glue inlet channel and the glue outlet.

[0011] Furthermore, a sealing chamber is provided on the outer side of the piston rod, the piston rod passes through the sealing chamber, one end of the piston rod extends to the outside of the sealing chamber, and the piston rod moves relative to the sealing chamber.

[0012] Furthermore, the glue-dispensing unit is provided in two sets.

[0013] Furthermore, the dispensing equipment also includes a moving component, which includes a vertical moving component, a horizontal moving component, and a forward and backward moving component. The vertical moving component is used to drive the dispensing unit to move vertically, the horizontal moving component is used to drive the dispensing unit to move horizontally, and the forward and backward moving component is used to drive the dispensing unit to move forward and backward.

[0014] Compared with the prior art, the advantages of this utility model include:

[0015] 1) The glue dispensing device provided by this utility model separates the dispensing holes of different glues, which can effectively prevent glue mixing and also prevent the glue outlet from being blocked due to the mixing of different glues at the dispensing port.

[0016] 2) The glue dispensing device provided by this utility model has a sealing chamber set on the outside of the piston rod. The sealing chamber is filled with lubricant. The lubricant is used to lubricate the piston rod on the one hand, and to isolate the glue material from the atmosphere on the other hand, so as to prevent the glue from contacting the atmosphere and causing the glue to solidify and block the glue outlet.

[0022] In view of the shortcomings of the prior art, the inventor of this case, through long-term research and extensive practice, has come up with the technical solution of this utility model. The following will further explain the technical solution, its implementation process, and its principles.

[0023] like Figure 1 , Figure 2 As shown, this utility model discloses a dispensing device, which includes a dispensing unit. The dispensing unit includes a cylinder base 1, a housing 2, a drive assembly 3, a nozzle connecting plate 4, and a nozzle 5. At least two cylinders 6 are provided inside the cylinder base 1. The number of cylinders 6 depends on the number of adhesives to be mixed. In this embodiment, two adhesives (adhesive A and adhesive B) need to be mixed, therefore, two cylinders 6 are provided in this embodiment. A piston rod 7 is provided inside each cylinder 6. The piston rod 7 is slidably connected to the cylinder 6, and moves relative to the cylinder 6 to achieve adhesive suction or discharge.

[0024] The housing 2 is fixedly connected to the cylinder base 1. The housing 2 is provided with at least two glue inlet channels. The number of glue inlet channels depends on the number of glues to be mixed together. In this embodiment, two different sets of glues need to be mixed together, so there are two glue inlet channels in this embodiment. One end of the glue inlet channel passes through the housing 2 to form a glue inlet 8. The glue inlet 8 is connected to an external glue tank through a pipe. The end of the glue inlet channel away from the glue inlet 8 corresponds to the position of the cylinder 6. The glue enters the cylinder 6 from the glue inlet channel. A part of the cylinder 6 is connected to the glue inlet channel. Under the drive of the piston rod 7, a negative pressure is formed in the cylinder 6, and the glue in the glue inlet channel enters the cylinder 6 to achieve glue suction. The other part of the cylinder 6 is connected to the glue outlet. Under the drive of the piston rod 7, the glue moves from the cylinder 6 to the glue outlet to achieve glue discharge.

[0025] The drive assembly 3 is connected to the end of the piston rod 7 away from the cylinder 6. Under the drive of the drive assembly 3, the piston rod 7 slides relative to the cylinder 6 to achieve glue suction and discharge. The drive assembly 3 includes a motor and a lead screw or a cylinder. In this embodiment, the drive assembly 3 includes a motor and a lead screw. The drive end of the motor is connected to the lead screw, and the lead screw is connected to the piston rod 7 through a connector. Under the drive of the motor, the piston rod 7 moves up and down relative to the cylinder 6.

[0026] The nozzle connecting plate 4 is provided with at least two dispensing holes. The number of dispensing holes depends on the number of adhesives to be mixed. In this embodiment, two adhesives need to be mixed, therefore two dispensing holes are provided. The positions of the dispensing holes correspond one-to-one with those of the cylinder 6, and some dispensing holes correspond to partial positions of the cylinder 6. The adhesive inside the cylinder 6 moves into the dispensing holes. The nozzle 5 is disposed on the nozzle connecting plate 4. The adhesive in the dispensing holes enters the nozzle 5, and the nozzle 5 is used at least to spray out the mixed adhesive. Multiple adhesives move from different dispensing holes to the nozzle 5, and the different adhesives are mixed within the nozzle 5.

[0027] This application separates the dispensing holes for different adhesives, which effectively prevents adhesive mixing and also avoids clogging of the dispensing holes caused by mixing of different adhesives at the dispensing holes.

[0028] In some implementations, the nozzle 5 is equipped with a dispensing cylinder, and the dispensing cylinder is equipped with a stirrer. Different adhesives entering the dispensing cylinder are stirred evenly by the stirrer. The stirrer is used to stir and mix the different adhesives mixed in the dispensing cylinder evenly.

[0029] In some implementation cases, a first blocking element is provided on the glue inlet channel. The first blocking element is used to control the opening and closing of the glue inlet channel. When the glue is injected, the first blocking element blocks the glue inlet channel to prevent the glue from entering the cylinder 6.

[0030] Based on the above, a second blocking member is provided on the glue outlet hole. The second blocking member is used to control the opening and closing of the glue outlet hole. When the glue is sucked, the second blocking member blocks the glue outlet hole to prevent glue from entering the glue outlet hole.

[0031] Based on the above, such as Figure 3 As shown, a material inlet / outlet valve assembly 12 is provided on one side of the housing 2. The material inlet / outlet valve assembly 12 is used to control the opening and closing of the glue inlet channel and the glue outlet.

[0032] In some implementations, a sealing chamber 11 is provided on the outer side of the piston rod 7, through which the piston rod 7 passes, with one end extending to the outside of the sealing chamber 11. The piston rod 7 moves relative to the sealing chamber 11. The sealing chamber 11 is filled with a lubricant, which serves two purposes: lubricating the piston rod 7 and isolating the adhesive material from the atmosphere to prevent the adhesive from hardening due to contact with the atmosphere, thus preventing blockage of the dispensing port.

[0033] In some implementations, the dispensing unit is provided in two sets, which can dispense two products simultaneously, thus improving dispensing efficiency.

[0034] In some implementations, the dispensing equipment further includes a moving component, which comprises a vertical moving component, a horizontal moving component, and a forward and backward moving component. The vertical moving component is used to drive the dispensing unit to move vertically, the horizontal moving component is used to drive the dispensing unit to move horizontally, and the forward and backward moving component is used to drive the dispensing unit to move forward and backward. Driven by the vertical moving component, the forward and backward moving component, and the horizontal moving component, the dispensing unit moves to the product to be dispensed to achieve dispensing.

[0035] It should be understood that the above embodiments are merely illustrative of the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
