Description

Technical Field

[0001] This utility model relates to the field of interior decoration technology, specifically to an edge glue injection device for interior decoration. Background Technology

[0002] Seam sealing is a common sealing, fixing and protective process that is widely used in construction, automobile manufacturing, electronic equipment and other fields. In construction, seams exist at the joints of components such as doors, windows, and curtain walls. Sealant injection fills these gaps, preventing the intrusion of air, rainwater, and dust, thus improving the building's airtightness and insulation, and reducing energy consumption. In automobile manufacturing, seam injection at the joints of various body parts enhances structural strength, prevents abnormal noises caused by vibration during driving, and also provides sound insulation, noise reduction, rust prevention, and corrosion protection. In electronic equipment, seam injection protects internal precision components, preventing short circuits caused by moisture and dust, while simultaneously securing internal components and improving equipment stability and reliability. Removing residual adhesive from the seam injection nozzles is primarily for ensuring aesthetic quality, as residual adhesive affects the overall appearance of the product; removal results in a clean and smooth surface. Secondly, residual adhesive may affect subsequent processes such as painting and bonding; removal ensures good adhesion between the new coating or adhesive and the substrate. Furthermore, residual adhesive may age and detach over time, forming tiny particles that contaminate the product's interior or the environment; removal prevents these problems and ensures the product's long-term performance and stability.

[0003] A search revealed that CN222314514U discloses an edge-sealing adhesive applicator for interior decoration. It includes a grip frame, with guide rods symmetrically arranged between the handle and a limiting ring. Two guide rods are located on one side of a support rod below the grip frame. A V-shaped plate is slidably arranged between the two guide rods. An inclined plate facing the adhesive nozzle is located at the bottom of the V-shaped plate. A caster wheel for auxiliary movement is installed at the bottom of the inclined plate. A support rod is located on the upper side of the inclined plate, and a locking bracket slides through the support rod. By using the V-shaped plate and inclined plate, along with the locking bracket and elastic elements, the V-shaped plate and inclined plate are fixed in the required positions. This not only meets the support requirements for different adhesive injection angles but also significantly improves the accuracy and stability of the adhesive injection operation. It effectively prevents deviations in the adhesive injection angle caused by operator fatigue, thus ensuring the consistency of the adhesive injection operation.

[0004] The problem with the above-mentioned edge-sealing adhesive device for interior decoration is that:

[0005] The existing slide bar extrusion plate requires two-handed operation, and the limited travel of the slide groove results in incomplete removal of residual adhesive. At the same time, the magnetic fixing method is prone to accidental detachment under vibration, thus resulting in inefficient operation of the residual adhesive removal mechanism. Utility Model Content

[0006] This utility model proposes an edge glue injection device for interior decoration, which solves the problems of existing technology where the sliding rod extrusion plate requires two-hand operation, the limited travel of the sliding groove leads to incomplete removal of residual glue, and the magnetic fixing method is prone to accidental detachment under vibration, thus resulting in inefficient operation of the residual glue removal mechanism.

[0007] The technical solution of this utility model is as follows: An edge glue injection device for interior decoration includes a glue gun barrel and a glue tube assembled inside the glue gun barrel. An extrusion assembly is provided on the front of the glue gun barrel corresponding to the glue outlet of the glue tube. The extrusion assembly includes two sets of elliptical extrusion blocks that mesh and rotate synchronously to extrude the glue outlet of the glue tube. A horizontal pushing assembly is also provided on the outside of the glue gun barrel to drive the elliptical extrusion blocks forward and thus cooperate with the elliptical extrusion blocks to remove residual glue from the glue outlet of the glue tube.

[0008] Preferably, the horizontal pushing component includes a rail base, which is fixedly connected to the outside of the glue gun barrel.

[0009] Preferably, the horizontal pushing component further includes a forward and reverse motor, which is fixedly installed inside the rail base. The horizontal pushing component also includes a threaded rod, which is fixedly connected to the output end of the forward and reverse motor. The threaded rod is rotatably connected to the inside of the rail base through the forward and reverse motor.

[0010] Preferably, the horizontal pushing assembly further includes a sliding sleeve, which is sleeved on the outside of the glue gun barrel and is threadedly connected to the threaded rod. The horizontal pushing assembly also includes a first bracket, which is symmetrically and fixedly connected to the side of the sliding sleeve. The horizontal pushing assembly also includes a second bracket, which is symmetrically and fixedly connected to the other side of the sliding sleeve.

[0011] Preferably, the side of the elliptical extrusion block is rotatably connected to the first support.

[0012] Preferably, the extrusion assembly further includes a bin seat, one side of which is fixedly connected to the second bracket. The extrusion assembly also includes a stepper motor, which is fixedly installed inside the bin seat. The output end of the stepper motor is fixedly connected to a rotating shaft, and a main gear plate is fixedly connected to the outside of the rotating shaft.

[0013] Preferably, the extrusion assembly further includes a connecting rod, which is rotatably connected to the side wall of the bin seat. One end of the connecting rod is fixedly connected to the elliptical extrusion block, and the other end of the connecting rod is fixedly connected to a secondary gear disc. The secondary gear disc is in contact with the main gear disc and is meshed and rotatably connected.

[0014] Preferably, the extrusion assembly further includes a sealing ring, which is fixedly connected to the side wall of the hopper seat, and the sealing ring corresponds to the position of the connecting rod.

[0015] The beneficial effects of this utility model are as follows:

[0016] I. Automated squeezing and removal mechanism

[0017] This patent uses a stepper motor to drive the meshing gear main and auxiliary gear discs, which in turn drive the elliptical extrusion block to rotate synchronously. Combined with a forward and reverse motor-driven threaded rod, horizontal pushing is achieved. The entire extrusion and residual adhesive removal actions are controlled by the motor. In contrast, the prior art CNU relies on manually sliding a V-shaped plate and magnetic fixation. This solution eliminates the need for hand operation, significantly improving efficiency, and the extrusion stroke is controllable, avoiding incomplete removal of residual adhesive.

[0018] II. Mechanical Stabilization and Precision Control

[0019] The threaded connection design between the sliding sleeve and the threaded rod, combined with the guide rail, ensures the linear and stable advancement of the extrusion block, eliminating the risk of vibration-induced detachment of the magnetically secured components as described in the comparison document. Simultaneously, the rotating extrusion of the elliptical extrusion block completely closes the glue tube outlet, preventing the glue from hardening during transportation and storage.

[0026] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0027] Please see Figure 1 and Figure 2 and Figure 3 and Figure 4 This utility model provides a technical solution: an edge glue injection device for interior decoration, including a glue gun barrel 1 and a glue tube 2 assembled inside the glue gun barrel 1. An extrusion component 4 is provided on the front of the glue gun barrel 1 corresponding to the glue outlet of the glue tube 2. The extrusion component 4 includes two sets of elliptical extrusion blocks 44 that mesh and rotate synchronously to extrude the glue outlet of the glue tube 2. A horizontal pushing component 3 is also provided on the outside of the glue gun barrel 1 to drive the elliptical extrusion blocks 44 forward and thus cooperate with the elliptical extrusion blocks 44 to remove residual glue from the glue outlet of the glue tube 2.

[0028] This design solves the problems of existing technologies where the sliding bar extrusion plate requires two-handed operation, the limited slide travel leads to incomplete removal of residual adhesive, and the magnetic fixing method is prone to accidental detachment under vibration, resulting in inefficient operation of the residual adhesive removal mechanism.

[0029] Please see Figure 2 The horizontal pushing component 3 includes a rail base 31, which is fixedly connected to the outside of the glue gun barrel 1.

[0030] In actual operation, a cover plate can be installed on the outside of the rail seat 31 to prevent glue impurities from entering the rail seat 31 and causing blockage of the threaded rod 321.

[0031] Please see Figure 2 The horizontal pushing component 3 also includes a forward and reverse motor 32, which is fixedly installed inside the rail base 31. The horizontal pushing component 3 also includes a threaded rod 321, which is fixedly connected to the output end of the forward and reverse motor 32. The threaded rod 321 is rotatably connected to the inside of the rail base 31 through the forward and reverse motor 32.

[0032] The horizontal pushing assembly 3 also includes a sliding sleeve 33, which is sleeved on the outside of the glue gun barrel 1 and is threadedly connected to the threaded rod 321. The horizontal pushing assembly 3 also includes a first bracket 331, which is symmetrically fixedly connected to the side of the sliding sleeve 33. The horizontal pushing assembly 3 also includes a second bracket 332, which is symmetrically fixedly connected to the other side of the sliding sleeve 33.

[0033] This design allows the sliding sleeve 33 to drive the extrusion assembly 4 horizontally under the drive of the forward and reverse motors 32. After the extrusion assembly 4 completes the extrusion at the outlet of the glue tube 2, this design can complete the task of pushing and removing residual glue.

[0034] Please see Figure 1 The side of the elliptical extrusion block 44 is rotatably connected to the first support 331;

[0035] The extrusion assembly 4 also includes a bin seat 41, one side of which is fixedly connected to the second bracket 332. The extrusion assembly 4 also includes a stepper motor 42, which is fixedly installed inside the bin seat 41. The output end of the stepper motor 42 is fixedly connected to a rotating shaft 421, and a main gear disk 422 is fixedly connected to the outside of the rotating shaft 421.

[0036] The extrusion assembly 4 also includes a connecting rod 431, which is rotatably connected to the side wall of the bin seat 41. One end of the connecting rod 431 is fixedly connected to the elliptical extrusion block 44, and the other end of the connecting rod 431 is fixedly connected to a secondary gear disk 43. The secondary gear disk 43 is in contact with the main gear disk 422 and is meshed and rotatably connected.

[0037] The extrusion assembly 4 also includes a sealing ring 45, which is fixedly connected to the side wall of the bin 41. The sealing ring 45 corresponds to the position of the connecting rod 431. The sealing ring 45 can prevent glue from entering the bin 41.

[0038] By starting the stepper motor 42 and rotating it in the meshing motion of the main gear plate 422 and the auxiliary gear plate 43, the two sets of elliptical extrusion blocks 44 can rotate, thereby completing the extrusion work at the outlet of the rubber tube 2.

[0039] Working principle:

[0040] When the glue tube 2 finishes injecting glue, there will be glue residue at the glue outlet. The stepper motor 42 can be started to drive the rotating shaft 421 and the main gear plate 422 to rotate. At this time, the auxiliary gear plate 43 meshing on the upper and lower sides of the main gear plate 422 will drive the connecting rod 431 and the elliptical extrusion block 44 to rotate and extrude the glue outlet of the glue tube 2.

[0041] Then, the forward and reverse motor 32 is started to drive the threaded rod 321 to rotate, which in turn causes the sliding sleeve 33, which is threaded to the outside of the threaded rod 321, to be pushed horizontally on the outside of the glue gun barrel 1. Together with the first bracket 331 and the second bracket 332, the elliptical extrusion block 44 is pushed to the outside of the glue outlet of the glue tube 2. This design can quickly clean and push out the glue residue at the outlet of the glue tube 2.

[0042] Specifically, the forward and reverse motors 32 and the stepper motor 42 are activated separately to complete the reset when the tube 2 is about to perform the next glue injection. This step ensures that the tube 2 is always squeezed and closed by the elliptical extrusion block 44 during the transportation and storage stage, thereby preventing the glue from curing.

[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
