Description

Technical Field

[0001] This utility model relates to the field of primer assembly technology, and in particular to a glue-applying mechanism for the primer joint of a gun cartridge. Background Technology

[0002] The primer is a crucial component of a bullet, and its structure is relatively simple, typically being directly pressed into the bottom of the cartridge case. Currently, to enhance the seal between the primer and the cartridge case and improve the connection strength, shellac is usually applied to the joint between the cartridge case and the primer, thus requiring a shellac application mechanism.

[0003] Existing glue application mechanisms mainly consist of an inflatable glue tank, a syringe, and a dispensing needle. Air pressure generated by inflating the glue tank propels the glue through the dispensing needle to cover the desired areas of the workpiece. For example, a glue application machine for sealing plugs disclosed in CN209631515U has the following drawbacks:

[0004] 1. Applying glue through a dispensing needle has a limited dispensing range, and manual wiping is required after dispensing, which is difficult, time-consuming and labor-intensive.

[0005] 2. As the amount of glue inside the inflatable glue tank decreases, the pressure will decrease, making it difficult to control the glue output and causing instability, requiring frequent adjustments.

[0006] 3. The adhesive is dispensed by air pressure extrusion and using a dispensing needle, which makes it impossible to accurately control the adhesive range and also causes adhesive to splatter everywhere during dispensing;

[0007] Based on this, this application provides a glue application mechanism for gun cartridge primer joints that is simple in structure, reasonably designed, can well control the glue application range, accurately control the glue dispensing amount, and has a stable glue dispensing amount, in order to solve the above problems. Utility Model Content

[0008] This invention aims to solve the technical problems of existing glue applicators, such as uncontrolled applicator range, glue splattering, and unstable glue output. To address these issues, this invention provides a simple, rationally designed glue applicator for gun cartridge primer seams that effectively controls the applicator range, precisely controls the glue output, and provides a stable glue output.

[0009] The technical solution adopted by this utility model to solve its technical problem is:

[0010] A glue-applying mechanism for the primer seam of a gun cartridge is provided, comprising a mounting frame, a glue bucket, a lifting cylinder, a movable seat, a dispensing bracket, a dispensing cylinder, a continuous injector, and a dispensing head. The glue bucket is fixedly mounted on one side of the top of the mounting frame, and the lifting cylinder is fixedly mounted on the other side of the top of the mounting frame. The bottom of the movable seat is fixedly connected to the piston rod of the lifting cylinder, and the dispensing bracket is fixedly mounted on its side.

The inlet is connected to the outlet of the glue bucket via a flexible hose. The dispensing head is mounted on the injection port of the continuous injector, and has multiple dispensing ports arranged in a ring directly opposite the primer seam of the gun cartridge.

[0011] In some optional embodiments, the dispensing head is connected to a continuous syringe via a Luer connector; the dispensing head consists of a connecting inner sleeve and a dispensing outer cylinder, one end of the connecting inner sleeve is screwed to the Luer connector, and the other end has a convex ring on its end face, the convex ring having a plurality of radial semi-circular grooves arranged in an annular array, one end of the dispensing outer cylinder is screwed to the connecting inner sleeve, its bottom abutting against the convex ring of the connecting inner sleeve, and the bottom of the dispensing outer cylinder has a plurality of dispensing ports arranged in an annular array near the outer side of the convex ring.

[0012] In some optional embodiments, a guide block is provided between the lifting cylinder and the movable seat, the guide block is fixed on the lifting cylinder, and the movable seat is provided with a guide groove that is slidably connected to the guide block.

[0013] In some alternative embodiments, a buffer is mounted on the bottom side of the cylinder body of the lifting cylinder via a fixed block, and a top block is fixedly mounted on the top side of the movable seat.

[0014] In some alternative embodiments, the glue bucket is made of a transparent material.

[0031] Example 1

[0032] As attached Figure 1 As shown, this embodiment provides a glue-applying mechanism for the primer joint of a gun ammunition cartridge, including a mounting frame 1, a glue tank 2, a lifting cylinder 3, a movable seat 4, a glue dispensing bracket 5, a glue dispensing cylinder 6, a continuous injector 7, and a glue dispensing head 8, wherein:

[0033] The glue bucket 2 is fixedly installed on one side of the top of the mounting frame 1 via a bucket rack. In this embodiment, the glue bucket 2 is preferably made of transparent material to facilitate viewing the remaining shellac in the bucket. The lifting cylinder 3 is fixedly installed on the other side of the top of the mounting frame 1. The bottom of the movable seat 4 is fixedly connected to the piston rod of the lifting cylinder 3, and the dispensing bracket 5 is fixedly installed on its side. The dispensing cylinder 6 is located on the top of the dispensing bracket 5. The cylinder of the continuous syringe 7 is fixedly installed on the dispensing bracket 5 directly below the dispensing cylinder 6, and its piston rod is fixedly connected to the piston rod of the dispensing cylinder 6. The inlet is connected to the outlet of the glue bucket 2 via a hose. The dispensing head 8 is installed at the injection port of the continuous syringe 7, and it has multiple dispensing ports 8.1 arranged in a ring directly opposite the primer seam of the gun cartridge. The diameter of the dispensing port is determined according to the design. In this embodiment, it can be designed as φ0.2mm.

[0034] Preferably, in this embodiment, a guide block 9 is further provided between the lifting cylinder 3 and the movable seat 4. The guide block 9 is fixed on the lifting cylinder 3, and the movable seat 4 is provided with a guide groove that is slidably connected to the guide block 9. This design increases the structural stability of the movable seat.

[0035] Preferably, in this embodiment, a buffer 10 is further installed on the bottom side of the lifting cylinder 3 via a fixing block, and a top block 4.1 is fixedly installed on the top side of the movable seat 4. This design allows the dispensing head to slow its descent speed when approaching the workpiece, enabling it to slowly come into contact with the workpiece.

[0036] Working Principle: Before production, adjust the volume adjusting nut on the continuous injector to determine the amount of shellac needed for a single operation. Control the dispensing cylinder to pull out the piston rod of the continuous injector, at which point the injector automatically draws in the corresponding volume of shellac (the injector has a visual glass tube to directly observe the amount of shellac drawn in each time). After the workpiece is in position, control the lifting cylinder to descend until the dispensing head is close to the workpiece (there is a slight gap between the dispensing head and the workpiece). Control the dispensing cylinder to advance the piston rod of the continuous injector, dispensing shellac and covering the specific area of ​​the workpiece (i.e., the primer seam of a gun cartridge). See attached diagram. Figure 4 As shown.

[0037] After the glue application is completed, pour out the shellac paint and inject alcohol. Manually apply the glue until alcohol comes out of the dispensing head. This completes the cleaning of the entire glue application mechanism. The cleaning is simple and convenient.

[0038] Example 2

[0039] Based on Embodiment 1, this embodiment further optimizes the design of the dispensing head 8. The dispensing head 8 in this embodiment is connected to the continuous syringe 7 via a Luer connector 11.

[0040] As attached Figure 2 and attached Figure 3 As shown, the dispensing head 8 in this embodiment consists of a connecting inner sleeve 8a and a dispensing outer cylinder 8b. One end of the connecting inner sleeve 8a is screwed to the Luer connector 11, and the end face of the other end is provided with a convex ring 8a.1. The convex ring 8a.1 has a plurality of radial semi-circular grooves 8a.1.1 arranged in an annular array. One end of the dispensing outer cylinder 8b is screwed to the connecting inner sleeve 8a, and its bottom abuts against the convex ring 8a.1 of the connecting inner sleeve 8a. The bottom of the dispensing outer cylinder 8b has a plurality of dispensing ports 81 arranged in an annular array near the outer side of the convex ring 8a.1.

[0041] The dispensing head designed in this embodiment can distribute the adhesive evenly between the convex ring and the bottom of the dispensing outer cylinder, making the adhesive dispensing from each outlet more uniform. This facilitates precise control of the adhesive dispensing amount and range at each outlet, resulting in better adhesive uniformity.

[0042] Example 3

[0043] Based on Embodiment 1 or Embodiment 2, this embodiment further includes an adhesive bonding assembly 12, as shown in the attached figure. Figure 1 As shown, the glue-receiving assembly 12 of this embodiment is located below the continuous injector 7. It includes a glue-receiving cylinder 12.1 fixedly installed on the fixed bracket 1 and a glue-receiving plate 12.2 provided on the piston rod of the glue-receiving cylinder. The glue-receiving plate 12.2 has a recess 12.2.1 directly facing the continuous injector 7. The recess can be used to directly receive the dripping shellac, or a glue-receiving cup can be fixedly installed in the recess to receive the dripping shellac.

[0044] In practice, before the lifting cylinder moves downward, the adhesive receiving assembly controls the adhesive receiving cylinder to pull the adhesive receiving plate back, and after the lifting cylinder resets, the adhesive receiving cylinder controls the adhesive receiving cylinder to push the adhesive receiving plate out.

[0045] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
