Description

Technical Field

[0001] This utility model relates to the field of dispensing machine technology, specifically a novel jewelry hot melt dispensing machine. Background Technology

[0002] In the jewelry manufacturing industry, hot melt dispensing machines are key equipment for jewelry setting, accessory bonding, and jewelry assembly. They melt solid hot melt adhesive through a hot melt adhesive valve and apply it to the surface of jewelry workpieces with precise flow and trajectory. Utilizing the rapid curing characteristic of hot melt adhesive, they achieve high-strength bonding, meeting the core requirements of jewelry manufacturing: "high precision, low damage, and high efficiency." In jewelry manufacturing scenarios, different workpieces have significantly different requirements for hot melt adhesive dispensing volume, nozzle diameter, and coating trajectory, necessitating frequent replacement of hot melt adhesive valves of different specifications to adapt to processing needs.

[0003] Based on the above, the inventors have discovered the following problems: the connection between the hot melt glue valve and the main unit of the existing jewelry hot melt dispensing machine relies on multiple bolts for fixing. When changing different specifications of glue valves, it is necessary to loosen and tighten the bolts one by one with special tools. The operation is cumbersome and time-consuming, and it is easy to damage other precision parts of the equipment. This has become a key bottleneck restricting the efficiency of jewelry processing and the service life of the equipment.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a new type of jewelry hot melt dispensing machine in order to achieve a more practical purpose. Utility Model Content

[0005] The purpose of this utility model is to provide a new type of jewelry hot melt dispensing machine to solve the problem mentioned in the background art that the connection between the hot melt dispensing valve and the main unit of the existing jewelry hot melt dispensing machine relies on multiple bolts for fixing.

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0007] A novel jewelry hot melt dispensing machine includes a moving mechanism and a dispensing mechanism. The moving mechanism includes a housing, with linear motors fixedly mounted on both sides of the upper end of the housing. A guide frame is fixedly mounted between the moving ends of a pair of linear motors. The dispensing mechanism includes several sliders and a quick-release frame. The sliders are slidably connected to the guide frame. A mounting frame is slidably mounted on one side of each slider. Moving grooves are formed on both sides of each mounting frame. Several grooves are formed on both sides of each moving groove. A pair of limiting blocks are fixedly mounted at both ends of one side of each quick-release frame. Each pair of limiting blocks is slidably connected to a pair of moving grooves. Through grooves are formed on both sides of each limiting block. Protrusions are provided inside each through groove, and the protrusions engage with the through grooves. A hot melt adhesive valve is fixedly mounted on the other side of the quick-release frame.

[0008] Furthermore, the quick-assembly frame has cavities at both ends, and a sleeve is rotatably connected to one end of each cavity. A screw is threaded into the inside of the sleeve, and the two sides of the screw are slidably connected to the two sides of the cavity, respectively.

[0009] The beneficial effect of adopting the above-mentioned further solution is that the sleeve and screw thread drive provide precise driving force for the extension and retraction of the protrusion, ensuring that the protrusion and the groove are firmly engaged, preventing the quick-release frame from loosening during dispensing, and ensuring the stability of dispensing.

[0010] Furthermore, a slide rod is fixedly installed at the other end of the cavity, and a movable rod is slidably sleeved on the slide rod, with one end of the movable rod fixedly connected to one end of the slide rod.

[0012] Furthermore, a pair of wedge blocks are fitted on the movable rod, and the pair of wedge blocks are mirror images of each other. The inclined surface of the wedge block abuts against the protrusion. Both ends of the quick-release frame are rotatably connected to knobs, and the central axis of one side of the knob is connected to one end of the sleeve.

[0013] The beneficial effect of adopting the above-mentioned further solution is that rotating the knob drives the sleeve to move the screw, and the wedge block's inclined surface squeezes the protrusion to extend and retract, thereby realizing the quick-release frame to lock or unlock quickly. The operation is convenient, requires no additional tools, and improves the efficiency of disassembly and assembly.

[0014] Furthermore, an electric telescopic rod is fixedly installed on one side of the upper end of the slider, and the bottom end of the electric telescopic rod is fixedly connected to the top end of the mounting frame.

[0015] The beneficial effect of adopting the above-mentioned further solution is that the electric telescopic rod drives the mounting bracket to move up and down, precisely adjusts the height of the hot melt adhesive valve, adapts to the dispensing needs of jewelry of different thicknesses, and improves the dispensing accuracy.

[0016] Furthermore, fixed brackets are fixedly installed on both sides of the upper end of the guide frame, and a synchronous pulley is rotatably connected to one side of each fixed bracket. A synchronous belt is wound between a pair of synchronous pulleys, and the bottom end of the synchronous belt is fixedly connected to the top end of the slider. A drive motor is fixedly installed on one side of one of the fixed brackets, and the output end of the drive motor is connected to one of the synchronous pulleys.

[0017] The beneficial effect of adopting the above-mentioned further solution is that the drive motor drives the slider to move smoothly along the guide frame through the synchronous pulley and synchronous belt, so as to achieve precise positioning of the jewelry dispensing position and improve the dispensing quality.

[0018] Furthermore, a pair of slide rails are fixedly installed on one side of the housing, and a fixed rod is slidably installed between the pair of slide rails. A connecting frame is fixedly installed on one side of the bottom end of the fixed rod, a first wire sleeve is installed on the bottom end of the connecting frame, and a second wire sleeve is fixedly installed on one side of the upper end of the fixed rod.

[0019] The beneficial effect of adopting the above-mentioned further solution is that the slide rail and the fixed rod slide together, which facilitates the adjustment of the position of the first and second wire sleeves, plays a guiding role in the hot melt adhesive tube, avoids the tube from getting tangled and affecting the dispensing action, and ensures smooth operation of the equipment.

[0020] Furthermore, a hot melt adhesive box is fixedly installed on one side of the box, and a controller is fixedly installed on the upper side of the box.

[0021] The advantages of adopting the above-mentioned further solutions are that the hot melt adhesive box continuously supplies hot melt adhesive to the hot melt adhesive valve; the controller is easy to set dispensing parameters and is intuitive and convenient to operate, improving the standardization and consistency of dispensing.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows: In this novel jewelry hot melt dispensing machine, the linear motor of the moving mechanism cooperates with the guide frame to drive the dispensing mechanism to achieve longitudinal movement; the slider slides with the guide frame and the mounting frame slides with the slider to achieve lateral movement of the hot melt adhesive valve; the quick-release frame is quickly locked and fixed by the limit block and the moving groove, and the protrusion and the groove, which facilitates the disassembly and replacement of the hot melt adhesive valve, adapts to different jewelry dispensing needs, and improves the flexibility and efficiency of dispensing; the sleeve and screw thread drive provide precise driving force for the extension and retraction of the protrusion, ensuring that the protrusion and the groove are firmly locked and prevent the quick-release frame from loosening during dispensing, thus ensuring the stability of dispensing; rotating the knob drives the sleeve to drive the screw to move, and the wedge block's inclined surface squeezes the protrusion to extend and retract, realizing the quick-release frame to lock or unlock quickly, which is convenient to operate, requires no additional tools, and improves disassembly and assembly efficiency.

A connecting frame 105 is fixedly installed on one side of the bottom end of the fixing rod 104, and a first wire sleeve 106 is installed on the bottom end of the connecting frame 105. A second wire sleeve 107 is fixedly installed on one side of the upper end of the fixing rod 104. The slide rails 103 and the fixing rod 104 slide together, which facilitates the adjustment of the positions of the first wire sleeve 106 and the second wire sleeve 107, and plays a guiding role in organizing the hot melt adhesive tube, avoiding the tube from getting tangled and affecting the dispensing action, and ensuring smooth operation of the equipment.

[0037] As an embodiment of this utility model, a hot melt adhesive tank 108 is fixedly installed on one side of the housing 101, and a controller 109 is fixedly installed on the upper side of the housing 101. The hot melt adhesive tank 108 continuously supplies hot melt adhesive to the hot melt adhesive valve 207.

[0038] Specifically, the working principle of this new type of jewelry hot melt dispensing machine is as follows: When in use, the hot melt adhesive tube is first passed through the first wire sleeve 106 and the second wire sleeve 107 to connect the hot melt adhesive tank 108 and the hot melt adhesive valve 207. The position of the fixing rod 104 is adjusted by the slide rail 103 to organize the pipeline. The limiting block 209 of the quick-installation frame 206 is inserted into the moving groove 204 of the mounting frame 203. The knob 210 is rotated to drive the sleeve 212 to drive the screw 213 to move. The wedge block 216 is used to squeeze the protrusion 211 into the corresponding groove 205 to quickly fix the hot melt adhesive valve 207. The dispensing parameters are set by the controller 109. The linear motor 102 drives the guide frame 110 to move longitudinally. The drive motor 113 drives the slider 201 to move laterally along the guide frame 110 through the synchronous wheel 112 and the synchronous belt 114. The electric telescopic rod 202 drives the mounting frame 203 to move up and down, realizing the three-dimensional positioning of the hot melt adhesive valve 207.
