Description

Technical Field

[0001] This utility model relates to the field of adhesive coating technology, and in particular to an adhesive coating device. Background Technology

[0002] Adhesive coating devices are widely used in industrial production, primarily for uniformly and controllably coating a layer of adhesive onto the surface of various substrates or objects. The core function of these devices relies on their coating component, the coating head, which spreads the adhesive through the relative movement between the coating head and the substrate surface.

[0003] During long-term squeegee operations, the squeegee head, as the working part that comes into direct contact with the adhesive and the substrate, will inevitably experience wear on its cutting edge or squeegee surface due to continuous friction, or be contaminated and clogged by cured or semi-cured adhesive residue.

[0004] Wear or contamination of the coating squeegee head can directly lead to a serious decline in coating quality, such as uneven coating thickness, missed areas, scratches, or streaks, which are unacceptable for precision coating processes. Therefore, the coating squeegee head is a high-frequency consumable part in the coating device and must be regularly maintained or replaced to ensure the stability of product quality.

[0005] However, many existing adhesive scraping devices prioritize secure fixing of the scraper head while neglecting ease of replacement. These structures are often complex, employing multiple bolts tightened at different angles or requiring the removal of multiple protective covers to access the fixing components. This results in cumbersome, time-consuming, and labor-intensive scraper head replacement procedures, necessitating extended downtime for operators to debug and assemble, severely impacting production continuity and overall efficiency. Therefore, this invention proposes an adhesive scraping device to address the shortcomings of existing technologies. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides an adhesive scraping device, which aims to improve the problem of complex disassembly and replacement structure after the scraper head wears and ages in some existing adhesive scraping devices.

[0007] This utility model provides an adhesive scraping device, including: a base; a sliding seat; a sliding assembly, the sliding assembly including a scraper head; and a disassembly and replacement mechanism.

[0008] The sliding seat is slidably connected to the top of the base. The removal and replacement mechanism is fixedly connected to the bottom of the sliding seat and is used to detachably fix the spray nozzle.

[0009] The disassembly and replacement mechanism includes a protective shell, screws, a rotating shaft, a clamping arm, and a rotating shaft. The screws are threaded into the protective shell and abut against the rotating shaft. The rotating shaft pushes the clamping arm, which is rotatably connected to the rotating shaft and used to clamp the coating head.

[0010] Preferably, the sliding assembly further includes a sliding ring and a limiting ring; the top of the applicator passes through the interior of the sliding ring, and the limiting ring abuts against the sliding ring.

[0011] Preferably, the outer side of the scraper head is provided with a groove, and the clamping arm clamps it inward into the groove.

[0012] Preferably, it also includes a drive mechanism; the drive mechanism, such as a pneumatic cylinder, is used to drive the sliding seat to slide along the length of the base.

[0013] Preferably, it also includes a fixing mechanism; the fixing mechanism is fixedly connected to the top of the base.

[0014] Preferably, the fixing mechanism includes an operating lever and a hinge; the operating lever is rotatably connected to the base of the fixing mechanism, and one end of the hinge is rotatably connected to the operating lever.

[0015] Preferably, the fixing mechanism further includes a linkage rod, a traction rod, and a pressure head; one end of the linkage rod is rotatably connected to the other end of the hinge, the traction rod is connected to the linkage rod, and the pressure head is fixedly connected to the end of the traction rod.

[0016] Preferably, it also includes a worktable; the worktable is located above the base, and the pressure head is located above the worktable and is used to press the object to be processed on the worktable.

[0017] This utility model has the following beneficial effects: 1.

It achieves the technical effect of quickly and conveniently replacing the coating head, ensuring the stability of coating quality, and significantly improving work efficiency.

[0018] 2. This utility model solves the problem in the prior art where objects on the worktable are prone to shifting during the coating process, resulting in decreased coating accuracy, uneven coating, or missed coating, by setting a fixing mechanism on the top of the base and using the lever linkage of the operating rod, hinge, linkage rod, and traction rod to control the pressure head. It achieves the technical effect of effectively pressing and fixing the workpiece to ensure accurate and stable coating operation.

[0019] 3. This utility model solves the problems of low maintenance efficiency and low processing accuracy that are common in the actual use of coating devices by combining the disassembly and replacement mechanism of the quick-change coating head with the fixing mechanism for stabilizing the workpiece, and by using the drive mechanism to drive the sliding seat to slide.

Detailed Implementation

[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] Example: Reference Figures 1 to 4 This utility model provides an adhesive scraping device, which aims to solve the problems in the prior art where the scraper head is worn and aged, and the disassembly and replacement are complicated, time-consuming, and affect the production efficiency and scraping quality stability.

[0024] like Figure 1 and Figure 2As shown, it includes a base 1 and a sliding seat 2 slidably connected to the top of the base 1. The base 1 serves as the mounting base for the entire device, while the sliding seat 2 is used to support the coating assembly and enable reciprocating motion.

[0025] Reference Figure 3 and Figure 4 The disassembly and replacement mechanism 3 is fixedly connected to the bottom of the sliding seat 2. The sliding component 36 is detachably fixed to the sliding seat 2 through the disassembly and replacement mechanism 3. The sliding component 36 includes a scraper head 361, a sliding ring 362 and a limiting ring 363. The disassembly and replacement mechanism 3 includes a protective shell 31, a screw 32, a rotating shaft 33, a clamping arm 34 and a rotating shaft 35.

[0026] The structure of the disassembly and replacement mechanism 3 is as follows: a screw 32 is threaded into the protective shell 31, one end of the screw 32 abuts against the rotating shaft 33, the rotating shaft 33 pushes the clamping arm 34, the clamping arm 34 is rotatably connected to the rotating shaft 35, and the rotating shaft 35 is fixed to the sliding seat 2 or the protective shell 31.

[0027] The top of the scraper head 361 passes through the interior of the sliding ring 362, and the limiting ring 363 abuts against the sliding ring 362. The outer side of the scraper head 361 is provided with a groove. When it is necessary to fix the scraper head 361, the screw 32 is turned in a specific direction. The screw 32 presses the rotating shaft 33, and the rotating shaft 33 pushes the clamping arm 34 to rotate inward around the rotating shaft 35, so that the clamping arm 34 is clamped into the groove of the scraper head 361, achieving a firm positioning.

[0028] A drive mechanism, such as a pneumatic cylinder, is used to drive the sliding seat 2 to slide along the length of the base (1). The drive mechanism is a conventional technology in the field and will not be described in detail here. It prevents the object on the worktable 5 from shifting. An adhesive scraping device also includes a fixing mechanism 4, which is fixedly connected to the top of the base 1 and is used to fix the object to be processed on the worktable 5.

[0029] Reference Figure 1 The fixing mechanism 4 includes an operating lever 41, a hinge 42, a linkage 43, a pulling rod 44, and a pressure head 45. The operating lever 41 is rotatably connected to the base of the fixing mechanism 4. One end of the hinge 42 is rotatably connected to the operating lever 41, and one end of the linkage 43 is rotatably connected to the other end of the hinge 42. The pulling rod 44 is connected to the linkage 43, and the pressure head 45 is fixedly connected to the end of the pulling rod 44. The mechanism also includes a worktable 5, which is located above the base 1. The pressure head 45 is located above the worktable 5. When the operating lever 41 is pulled down, the hinge 42 drives the linkage 43 to rotate, and the linkage 43 pulls the pulling rod 44, causing the pressure head 45 to move downward, ultimately pressing the workpiece on the worktable 5.

[0030] Reference Figure 2 and Figure 3The sliding assembly 36 also includes a sliding ring 362 and a limiting ring 363. The top of the scraper head 361 passes through the interior of the sliding ring 362, and the limiting ring 363 abuts against the sliding ring 362 to provide pre-positioning for the subsequent clamping of the clamping arm 34.

[0031] Reference Figure 4 The outer side of the scraper head 361 is provided with a groove. Under the push of the screw 32 and the rotating shaft 33, the clamping arm 34 clamps the clamping end into the groove to form a stable limit fixation. It also includes a drive mechanism, such as a pneumatic cylinder connected to the sliding seat 2, for driving the sliding seat 2 to slide along the length direction of the base (1) to realize the scraping stroke.

[0032] Reference Figure 1 The fixing mechanism 4 is fixedly connected to the top of the base 1. The fixing mechanism 4 includes an operating rod 41 and a hinge 42. The operating rod 41 is rotatably connected to the base of the fixing mechanism (4), and one end of the hinge 42 is rotatably connected to the operating rod 41.

[0033] The fixing mechanism 4 also includes a linkage rod 43, a pulling rod 44, and a pressing head 45. One end of the linkage rod 43 is rotatably connected to the other end of the hinge 42. The pulling rod 44 is connected to the linkage rod 43. The pressing head 45 is fixedly connected to the end of the pulling rod 44. Through this set of linkage lever structures, the rotation action of the operating rod 41 is converted into the vertical pressing action of the pressing head 45.

[0034] Reference Figure 1 It also includes a worktable 5, which is located above the base 1. The pressure head 45 is located above the worktable 5 and is used to press the object to be processed on the worktable 5 to prevent the object from shifting during the coating process.

[0035] The implementation principle of this application embodiment is as follows: When it is necessary to perform a scraping operation on the object on the workbench 5, the operating lever 41 is first pulled down. The operating lever 41 drives the linkage rod 43 to rotate through the hinge 42. The linkage rod 43 then drives the traction rod 44, causing the pressure head 45 at the end of the traction rod 44 to move downward, and finally fix the object tightly on the top of the workbench 5 to prevent displacement during subsequent processing. When the operating lever 41 is pulled up, the pressure head 45 is lifted upward.

[0036] After the object is fixed, the drive mechanism is activated, which pushes the sliding seat 2 to slide along the length of the base 1. The scraper head 361 installed on the sliding seat 2 then performs adhesive scraping on the surface of the object on the worktable 5.

[0037] When the coating head 361 is worn or aged and needs to be replaced, turn the screw 32 inside the protective shell 31 in the opposite direction to tightening. The pressure of the screw 32 on the rotating shaft 33 decreases, and the clamping arm 34 opens outward around the rotating shaft 35 under the action of the elastic element, releasing the clamping of the groove of the coating head 361. At this time, the old coating head 361 can be quickly removed. When installing the new coating head 361, first pass the top of the coating head 361 through the sliding ring 362, so that the limiting ring 363 presses against the sliding ring 362. Then turn the screw 32 inward. The screw 32 squeezes the rotating shaft 33, and the rotating shaft 33 pushes the clamping arm 34 to clamp inward around the rotating shaft 35 until the clamping arm 34 is firmly clamped into the groove of the coating head 361, completing the replacement. The whole process is convenient to operate, greatly improving production efficiency and ensuring coating quality.
