Description

Technical Field

[0001] This utility model relates to the field of glass installation and adhesive injection technology, and in particular to a precise adhesive injection volume control device. Background Technology

[0002] In the field of architectural decoration, the application of sealant during the installation of floors and glass is a crucial step in ensuring the stability and airtightness of the spatial structure. As architectural designs increasingly demand aesthetics and functionality, the limitations of traditional sealant application methods are becoming increasingly apparent.

[0003] Currently, the application of adhesive during flooring and glass installation is mostly done manually using handheld adhesive guns. Manual adhesive application heavily relies on the worker's skill and experience in controlling the amount of adhesive dispensed. In large-area flooring and glass splicing scenarios, it is difficult to maintain a stable application speed and pressure for extended periods, easily leading to inconsistent adhesive joint widths and thicknesses, affecting the aesthetic appeal. Furthermore, there is a risk of insufficient adhesive application in certain areas, resulting in decreased sealing and structural loosening, among other safety hazards. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a precise glue injection control device that replaces manual glue extrusion, thus avoiding the problem of manual glue injection speed and pressure being difficult to maintain for a long time and controlling the glue output.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A precision glue dispensing control device includes a housing. A fixed head is fixedly connected to the left end of the housing, and a through hole is provided in the middle of the fixed head. A movable rod that slides left and right is provided at the right end of the housing. A push plate is rotatably connected to the left end of the movable rod. Fixed blocks are fixedly connected to the lower sides of both the left and right ends of the housing. A lead screw is rotatably connected to the middle of the fixed block at the left end of the housing. A rod sleeve is threaded onto the outside of the lead screw. The right end of the rod sleeve passes through the middle of the fixed block at the right end of the housing. A connecting plate is fixedly connected to the outside of the right end of the rod sleeve. The upper end of the connecting plate is fixedly connected to the outside of the right end of the movable rod. A motor is fixedly connected to the left side of the fixed block at the left side of the housing. The drive end of the motor is fixedly connected to the left end of the lead screw.

[0007] Furthermore, a limiting ring is fixedly connected to the outside of the right end of the lead screw, and the outer wall of the limiting ring is movably connected to the inside of the rod sleeve.

[0008] Furthermore, a protective cover is fixedly connected to the opposite side of the fixed block, and an arc-shaped plate that slides left and right is provided on the outer side of the protective cover. A first fastener is threadedly connected to the front side of the arc-shaped plate.

[0009] Furthermore, a handle is fixedly connected to the lower side of the arc-shaped plate.

[0010] Furthermore, the handle is externally movably provided with an adjustment handle, and the upper end of the adjustment handle is threadedly connected to a second fastener.

[0011] Furthermore, a cover plate is provided on the upper side of the housing, the left end of the cover plate is rotatably connected to the right side of the fixing head, and a pull ring is fixedly connected to the upper right end of the cover plate.

[0012] Furthermore, a movable ring that moves left and right is provided on the outer right end of the housing.

[0022] 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.

[0023] Reference Figure 1 , Figure 2 and Figure 4 This utility model provides an embodiment of a precision glue injection control device, comprising a housing 1, a fixed head 2 fixedly connected to the left end of the housing 1, a through hole provided in the middle of the fixed head 2, a movable rod 3 that slides left and right at the right end of the housing 1, a push plate 4 rotatably connected to the left end of the movable rod 3, fixed blocks 5 fixedly connected to the lower sides of both the left and right ends of the housing 1, a lead screw 6 rotatably connected to the middle of the fixed block 5 at the left end of the housing 1, a rod sleeve 8 threadedly connected to the outside of the lead screw 6, the right end of the rod sleeve 8 passing through the middle of the fixed block 5 at the right end of the housing 1, and the right end of the rod sleeve 8 being externally fixed... A connecting plate 10 is fixedly connected, and the upper end of the connecting plate 10 is fixedly connected to the outside of the right end of the movable rod 3. A motor 7 is fixedly connected to the left side of the left side fixing block 5 of the housing 1. The driving end of the motor 7 is fixedly connected to the left end of the lead screw 6. A limit ring 9 is fixedly connected to the outside of the right end of the lead screw 6. The outer wall of the limit ring 9 is movably connected to the inside of the rod sleeve 8. A cover plate 11 is provided on the upper side of the housing 1. The left end of the cover plate 11 is rotatably connected to the right side of the fixing head 2. A pull ring 12 is fixedly connected to the upper side of the right end of the cover plate 11. A movable ring 13 that moves left and right is provided on the outside of the right end of the housing 1.

[0024] The operator pulls the pull ring 12 upwards, causing the cover plate 11 to rotate and open around the hinge point on the right side of the fixed head 2, exposing the internal cavity of the housing 1. The standard glue tube is then placed into the inner cavity of the housing 1, ensuring that the glue tube outlet is accurately inserted into the through hole in the middle of the fixed head 2 and passes through the through hole. After closing the cover plate 11 in the reverse direction, the movable ring 13 is slid to the left to cover the connection part of the cover plate 11, forming a mechanical locking structure. After starting the motor 7, its output shaft drives the lead screw 6 to perform precise rotational motion. The rotating lead screw 6 engages with the internal thread of the sleeve 8, converting the rotational motion into linear motion. When the sleeve 8 moves to the right, the limiting ring 9 contacts the inner wall of the sleeve 8 to form a mechanical stop, preventing excessive travel. The sleeve 8 drives the movable rod 3 to move synchronously through the connecting plate 10, and the pushing plate 4 evenly transmits the mechanical thrust to the glue tube piston, achieving stable glue extrusion.

[0025] Reference Figures 1-3A protective cover 14 is fixedly connected to the opposite side of the fixed block 5. An arc-shaped plate 15 that can slide left and right is provided on the outside of the protective cover 14. A first fastener 16 is threadedly connected to the front side of the arc-shaped plate 15. A handle 17 is fixedly connected to the lower side of the arc-shaped plate 15. An adjustment handle 18 is movably provided on the outside of the handle 17. A second fastener 19 is threadedly connected to the upper end of the adjustment handle 18.

[0026] The arc-shaped plate 15 can move left and right outside the protective cover 14 to adjust the position of the handle 17. The first fastener 16 can be rotated to fix the arc-shaped plate 15. The left and right positions of the handle 17 can be adjusted by sliding the arc-shaped plate 15 to balance the change in the center of gravity of the device caused by the reduction of glue amount. The adjustment handle 18 can extend and retract outside the handle 17 to adjust the length and facilitate glue injection at high places.

[0027] Working principle: Pulling the pull ring 12 drives the cover plate 11 to rotate and open it, placing the glue tube inside the housing 1 so that its glue outlet passes through the fixed head 2. Closing the cover plate 11 pushes the movable ring 13 to the left, covering the outside of the cover plate 11 and fixing it. The motor 7 is started to drive the lead screw 6 to rotate. The rotating lead screw 6 drives the rod sleeve 8 to move to the left, thereby driving the movable rod 3 and the push plate 4 to move to the left through the connecting plate 10. The push plate 4 stably extrudes the glue. The arc plate 15 can move left and right outside the protective cover 14 to adjust the position of the handle 17. Rotating the first fastener 16 can fix the arc plate 15. As the glue is extruded, the center of gravity gradually moves to the left, moving the handle 17 to the left to reduce hand fatigue. The adjustable handle 18 can extend and retract outside the handle 17 to adjust the length, making it convenient to inject glue at high places.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
