Description

Technical Field

[0001] This application relates to the field of dispensing machine technology, and in particular to a nozzle mechanism for a dispensing machine. Background Technology

[0002] As is well known, a dispensing machine, also called a glue applicator, glue dripper, glue applicator, or glue potting machine, is an automated machine specifically designed to control fluids and apply them dropwise or in the form of glue onto the surface or interior of a product. It can achieve three-dimensional and four-dimensional path dispensing, precise positioning, accurate glue control, and prevent stringing, leakage, or dripping. Dispensing machines are mainly used in product manufacturing processes to precisely dispense, inject, coat, or drip adhesives, paints, and other liquids onto specific locations on each product. They can be used to create dots, lines, circles, or arcs.

[0003] Currently, in related technologies, a search reveals that a utility model with patent publication number CN208466356U discloses a high-life dispensing machine nozzle mechanism. By setting wear-resistant linings and wear-resistant parts in the spray pipe section and nozzle section, the wear resistance of the nozzle inner wall is effectively improved. However, the applicant has found that the following defects still exist: for hot melt adhesives or paraffin-based adhesives that need to be heated to 80-150℃, it is difficult to control the temperature of the nozzle to ensure the fluidity of the adhesive, which can easily lead to uneven dispensing or clogging. At the same time, in low-temperature environments, the fluidity of high-viscosity adhesives will also deteriorate, which will also affect the dispensing accuracy.

[0004] Therefore, in response to the aforementioned technologies, we propose a nozzle mechanism for a dispensing machine. Utility Model Content

[0005] The purpose of this invention is to provide a nozzle mechanism for a dispensing machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A nozzle mechanism for a dispensing machine, comprising:

[0008] Two arc-shaped plates are hinged together by a connecting component, and the other ends of the two arc-shaped plates are connected by a limiting component.

[0009] Multiple circular plates are symmetrically arranged at one end of two arc-shaped plates, and a composite spring is fixedly connected to the circular plates, and a composite suction cup is fixedly connected to the other end of the composite spring.

[0010] Multiple mounting blocks are symmetrically arranged at opposite ends of two arc-shaped plates, and the mounting blocks are divided into groups of two, with a heating tube between the two mounting blocks in the same group.

[0011] As a further embodiment of this utility model: the connecting component includes two connecting blocks, both of which are symmetrically arranged at one end of the arc-shaped plate, and a connecting rod is provided between the connecting blocks. A connecting seat is rotatably provided on the outside of the connecting rod, and the other end of the connecting seat is fixedly connected to another arc-shaped plate.

[0012] As a further improvement of this utility model: the connecting seat has a connecting hole and a connecting ring is provided in the connecting hole, and the connecting seat is rotatably connected to the connecting rod through the connecting ring.

[0013] As a further embodiment of this utility model: the limiting component includes two safety locks and two safety buckles, the two safety locks and the two safety buckles are symmetrically arranged on the outer wall of the two arc-shaped plates, and the safety locks and safety buckles are adapted to each other, and the safety locks are provided with an adjustment panel.

[0014] As a further improvement of this utility model: two strip handles are fixedly connected to the outer walls of the two arc-shaped plates, and the outer surfaces of the strip handles are fitted with anti-slip rubber sleeves.

[0015] As a further improvement of this utility model, two shielding plates are symmetrically arranged at opposite ends of the two arc-shaped plates.

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

[0017] The two arc-shaped plates, in conjunction with the connecting and limiting components, allow for flexible opening and locking, facilitating the installation of the two arc-shaped plates on the outside of the dispensing machine's glue output line. A strip handle and anti-slip rubber sleeve enhance operation. A composite spring and suction cup on the circular plate form an adsorption structure, securing the two arc-shaped plates to the outside of the dispensing machine's glue output line. The heating element between the mounting blocks provides precise temperature control over the glue output line area. The appropriate heating range can be set via the control panel, ensuring good flowability of hot melt adhesives or high-viscosity adhesives and preventing uneven dispensing or blockage due to insufficient temperature. A baffle plate prevents heat loss from the heating element and avoids glue splashing that contaminates the heating element. The overall structure is relatively simple, with each component working together to achieve precise glue temperature control. This effectively solves the problems of poor glue flowability and insufficient hot melt adhesive temperature control in low-temperature environments, improving dispensing accuracy and equipment applicability.

[0023] 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.

[0024] The present application will be further described in detail below with reference to the accompanying drawings.

[0025] Please see Figures 1-4 In this embodiment of the present invention, a nozzle mechanism for a dispensing machine includes:

[0026] Two curved plates 1 are hinged together by a connecting component, and the other ends of the two curved plates 1 are connected by a limiting component.

[0027] Multiple circular plates 2 are symmetrically arranged at opposite ends of two arc-shaped plates 1, and a composite spring 3 is fixedly connected to the circular plate 2, and a composite suction cup 4 is fixedly connected to the other end of the composite spring 3.

[0028] Multiple mounting blocks 5 are symmetrically arranged at opposite ends of two arc-shaped plates 1, and the multiple mounting blocks 5 are divided into two groups of two. A heating tube 6 is arranged between two mounting blocks 5 in the same group.

[0029] In use, the nozzle mechanism of this dispensing machine opens two arc-shaped plates 1 via a connecting assembly, wrapping the mechanism around the outside of the dispensing machine's glue output pipeline. This allows the composite suction cup 4 to adhere to the outer surface of the glue output pipeline. The arc-shaped plates 1 are then locked by the safety lock 11 and safety buckle 12 of the limiting assembly. Subsequently, the appropriate temperature of the heating tube 6 is set via the control panel 13 on the safety lock 11 to heat the glue pipeline area, ensuring that hot melt adhesive or high-viscosity adhesive maintains good fluidity. After the dispensing operation is completed, the safety lock 11 is released to open the arc-shaped plates 1, and the composite spring 3 returns to its original position, causing the composite suction cup 4 to detach from the glue output pipeline. If maintenance is required, the arc-shaped plates 1 can be rotated via the connecting assembly to expose the glue pipeline for cleaning or component replacement. Throughout the process, all components work together to achieve precise control of the glue temperature.

[0030] exist Figure 1-3 In the middle: the connecting component includes two connecting blocks 7, which are symmetrically arranged at one end of the arc plate 1, and a connecting rod 8 is provided between the connecting blocks 7. A connecting seat 9 is rotatably provided on the outside of the connecting rod 8. The other end of the connecting seat 9 is fixedly connected to another arc plate 1. A connecting hole is opened in the connecting seat 9, and a connecting ring 10 is provided in the connecting hole. The connecting seat 9 is rotatably connected to the connecting rod 8 through the connecting ring 10.

[0031] The nozzle mechanism of this dispensing machine allows the two arc-shaped plates 1 to rotate flexibly around the connecting rod 8 to open and close. The connecting ring 10 reduces rotational friction loss and ensures that the arc-shaped plates 1 open and close smoothly, providing a detachable hinged base for equipment installation and maintenance.

[0032] exist Figure 1-4 The limiting component includes two safety locks 11 and two safety buckles 12. The two safety locks 11 and two safety buckles 12 are symmetrically arranged on the outer wall of the two arc-shaped plates 1, and the safety locks 11 and safety buckles 12 are adapted to each other. The safety locks 11 are provided with an adjustment panel 13.

[0033] The nozzle mechanism of this dispensing machine, through this structure, allows the arc plate 1 to wrap around the glue pipeline and lock it with the safety lock 11 to prevent the mechanism from loosening during the dispensing process. At the same time, the position of the control panel 13 allows the operator to directly set the heating temperature in the locked state, realizing the integrated operation of temperature control and locking functions.

[0034] exist Figure 1-4In the middle: Two strip handles 14 are fixedly connected to the outer walls of the two arc-shaped plates 1. The outer side of the strip handles 14 is fitted with anti-slip rubber sleeves 15. Two baffles 16 are symmetrically arranged at opposite ends of the two arc-shaped plates 1. The combination of the strip handles 14 and the anti-slip rubber sleeves 15 improves the grip comfort and friction, making it easier for operators to open and close the arc-shaped plates 1. The baffles 16 cover the outside of the heating tube 6, which can reduce the heat loss of the heating tube 6 to the outside, and prevent glue from splashing and contaminating the heating element during the dispensing process, thus ensuring the temperature control efficiency and cleanliness of the equipment.

[0035] In this embodiment, the heating tube 6 is a commercially available device known to those skilled in the art. It can be customized or selected according to actual needs. Here, we are only using it without making any structural or functional improvements. We will not go into details here. The heating tube 6 is equipped with a matching control switch. The installation position of the control switch is selected according to actual usage needs to facilitate operation and control by the operator. The technology is already very mature and can be implemented.

[0036] The implementation principle of a dispensing machine nozzle mechanism in this application embodiment is as follows: First, through the rotational cooperation of connecting block 7, connecting rod 8, connecting seat 9 and connecting ring 10, two arc-shaped plates 1 can be flexibly opened and closed to wrap the glue output pipeline of the dispensing machine. Then, the safety lock 11 and safety buckle 12 lock to form a closed structure. The strip handle 14 and anti-slip rubber sleeve 15 facilitate the operator to hold and adjust the opening and closing angle. Then, through the mutual cooperation of composite spring 3 and composite suction cup 4 on the circular plate 2, the adsorption force generated by the elastic deformation of the spring promotes the stable fixation of the mechanism and avoids the shaking phenomenon during use. The heating tube 6 between the mounting blocks 5 is precisely temperature controlled by the control panel 13 to heat the glue pipeline area to maintain the appropriate fluidity of the glue. The shielding plate 16 covers the outside of the heating tube 6 to prevent heat loss and prevent glue splashing and contamination of the heating element. The synergistic effect of each component realizes the precise control of the glue temperature, effectively solving the problems of poor glue fluidity and insufficient temperature control of hot melt glue in the prior art under low temperature conditions.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
