Description

Technical Field

[0001] This utility model relates to the field of adhesive coating equipment technology, specifically an automatic adhesive coating device for flap wheel production. Background Technology

[0002] A flap wheel, also known as a high-strength elastic grinding disc, is made of plastic or fiber mesh covered with abrasive cloth sheets. The production of flap wheels involves multiple processes, including bonding. Before bonding, an adhesive applicator is often used to apply adhesive to the base of the flap wheel before the abrasive cloth sheets are bonded to the base. Patent document CN220573896U discloses an automatic adhesive applicator for flap wheel production. This device employs a locking assembly design. Specifically, a first electric push rod retracts, causing a connecting block to move downwards. The movement of the connecting block moves a connecting rope, providing tension to pull the locking block into a telescopic groove. The flap wheel base is then aligned with the limiting post and placed on the turntable. The first electric push rod extends, causing the connecting block to move upwards and loosen the connecting rope. The spring's reaction force causes the locking block to return and extend, locking the flap wheel base in place. This effectively improves the stability of the flap wheel base and prevents it from easily shaking or flying off.

[0003] The aforementioned device and technical solution also have some shortcomings. Because the rope needs to be frequently pulled down and released during locking and positioning, repeated strong friction occurs between the rope and the pre-drilled holes in the limiting post, easily accelerating physical fatigue and wear breakage of the rope. Therefore, it is necessary to design an automatic gluing device for flap wheel production to solve the problems mentioned above. Utility Model Content

[0004] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0005] Therefore, the purpose of this utility model is to provide an automatic gluing device for the production of flap wheels, so as to solve the problem that the automatic gluing device for the production of flap wheels in the prior art mentioned in the background art requires frequent pulling of the soft rope down and releasing during locking and positioning, which can lead to repeated strong friction between the soft rope and the reserved wire hole of the limit post, which can easily accelerate the physical fatigue and wear and breakage of the soft rope.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic glue-applying device for producing leaf rollers, comprising a base, wherein a turntable is movably mounted on the upper part of the base and driven by a drive device to rotate horizontally and radially;

[0007] The locking and positioning device includes a main gear that is horizontally rotatably mounted at the top axis of the turntable. The main gear is driven to rotate by a drive device. At least three half gears are horizontally meshed around the main gear. A push rod is fixed on the opposite side of the half gear that meshes with the main gear. The multiple push rods are evenly distributed along the radial periphery of the main gear. The multiple push rods abut against and position the inner circular hole of the flap wheel base.

[0008] A glue box is provided at the upper rear end of the base, and a glue gun assembly is provided at the upper front end of the glue box.

[0009] As a preferred embodiment of the automatic glue-applying device for producing leaf wheels according to this utility model, the base is provided with a second motor that can drive the turntable to rotate horizontally, and the upper part of the base is also provided with a mounting groove corresponding to the turntable.

[0010] As a preferred embodiment of the automatic gluing device for producing leaf wheels according to this utility model, a first rotating shaft is fixed at the bottom axis of the main gear, a motor is fixed at the center of the turntable and its output shaft is fixedly connected to the first rotating shaft, and a second rotating shaft is fixed at the bottom axis of the half gear and rotatably mounted on the turntable.

[0011] In a preferred embodiment of the automatic glue-applying device for producing leaf rollers described in this utility model, a rubber head is also fixed to the outer end of the top rod.

[0012] As a preferred embodiment of the automatic glue-applying device for producing flap wheels according to this utility model, the locking and positioning device further includes a disc cover covering the outside of the main gear, half gear, push rod and rubber head, and the disc cover has multiple telescopic openings around its periphery corresponding to each push rod.

[0013] As a preferred embodiment of the automatic glue-applying device for flap wheel production described in this utility model, the glue-applying gun assembly includes a first electric push rod horizontally fixed to the upper end of the glue tank, a second electric push rod vertically installed at the output end of the first electric push rod, and a glue-applying gun disposed at the bottom output end of the second electric push rod.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the automatic glue-applying device for flap wheel production, through the rubber head, can effectively increase the contact area and friction between the push rod and the flap wheel base, without causing wear to the flap wheel base. Specifically, in this embodiment, by placing the flap wheel base on the turntable with its inner opening fitted outside the disc cover, the starting motor drives the main gear and three half gears to rotate synchronously, causing the push rod, which was originally retracted inside the disc cover, to swing out. The three radial push rods and the rubber head abut and fix the inner opening of the flap wheel base, forming a coaxial locking and positioning between the flap wheel base and the turntable, thereby preventing the flap wheel base from shaking and flying off. Moreover, compared with the prior art, its structure is more reasonable and its operation is more stable, and its practicality is better. Attached Figure Description

Detailed Implementation

[0020] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0021] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views showing the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, in actual manufacturing, the three-dimensional spatial dimensions of length, width, and depth should be included.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0023] Figures 1-4 The diagram shown is a complete structural schematic of an automatic glue-applying device for flap wheel production according to this utility model. Please refer to [link / reference]. Figures 1-4 An automatic glue-applying device for flap wheel production according to this embodiment includes a base 100, on which a turntable 200 is movably mounted and driven by a drive device to rotate horizontally and radially. A locking and positioning device 300 includes a main gear 310 horizontally mounted at the top axis of the turntable 200. The main gear 310 is driven by the drive device to rotate. At least three half gears 320 are horizontally meshed around the main gear 310. A push rod 330 is fixed on the opposite side of the half gear 320 that meshes with the main gear 310. The multiple push rods 330 are evenly distributed along the radial periphery of the main gear 310 and are used to abut and position the flap wheel base through the multiple push rods 330. A glue tank 500 is also provided at the upper rear end of the base 100, and a glue-applying gun assembly 600 is provided at the upper front end of the glue tank 500.

[0024] The base 100 houses a second motor 400 capable of driving the turntable 200 to rotate horizontally. The upper part of the base 100 also has a mounting groove corresponding to the turntable 200. It is understood that the turntable 200 has a sufficient diameter to accommodate different sizes of flap wheel bases. During use, the second motor 400 drives the turntable 200, the locking and positioning device 300, and the flap wheel bases to rotate horizontally, allowing the glue gun assembly 600 to apply glue circumferentially to the surface of the flap wheel bases. A first rotating shaft 311 is fixed at the bottom axis of the main gear 310. A first motor 360 is fixed at the center of the turntable 200, with its output shaft fixedly connected to the first rotating shaft 311. A second rotating shaft 321 is fixed at the bottom axis of the half gear 320 and rotatably mounted on the turntable 200. A rubber head 340 is fixed to the outer end of the push rod 330. The rubber head 340 effectively increases the contact area and friction between the push rod 330 and the flap wheel base without causing wear to the flap wheel base. Specifically, in this embodiment, by placing the flap wheel base on the turntable 200 and fitting its inner opening onto the outside of the disc cover 350, the motor 360 is started and drives the main gear 310 and the three half gears 320 to rotate synchronously. This causes the push rod 330, which was originally retracted inside the disc cover 350, to swing out. The three radial push rods 330 and the rubber head 340 abut and fix the inner opening of the flap wheel base, forming a coaxial locking and positioning between the flap wheel base and the turntable 200. This prevents the flap wheel base from shaking or flying off. Compared with the prior art, its structure is more reasonable and its operation is more stable, making it more practical.

[0025] Furthermore, the locking and positioning device 300 also includes a disc cover 350 covering the outside of the main gear 310, half gear 320, push rod 330 and rubber head 340. The disc cover 350 has multiple telescopic openings 351 around its perimeter that correspond to each push rod 330. The disc cover 350 can provide external protection for the main gear 310 and half gear 320, while also ensuring safe operation for the user and improving the appearance.

[0026] Furthermore, the glue application gun assembly 600 includes a first electric push rod 610 horizontally fixed to the upper end of the glue tank 500, a second electric push rod 620 vertically mounted to the output end of the first electric push rod 610, and a glue application gun 630 disposed at the bottom output end of the second electric push rod 620. Since different specifications of flap wheel bases have different outer diameters, it means that the areas requiring glue application will deviate. Therefore, by using the first electric push rod 610 to push the second electric push rod 620 and the glue application gun 630 back and forth, the extrusion end of the glue application gun 630 is aligned with the glue-to-be-applied line on the flap wheel base, which is simple and practical.

[0027] In summary, the automatic glue-applying device for flap wheel production according to this embodiment, when in use, involves placing the flap wheel base on the turntable 200 with its inner opening fitted onto the outside of the disc cover 350. Starting the motor 360 drives the main gear 310 and three half gears 320 to rotate synchronously, causing the push rod 330, which was originally retracted inside the disc cover 350, to swing out. The three radial push rods 330 and the rubber head 340 then abut and fix the inner opening of the flap wheel base, creating a coaxial locking and positioning between the flap wheel base and the turntable 200. Subsequently, the motor 400 drives the turntable 200, the locking and positioning device 300, and the flap wheel base to rotate horizontally, allowing the glue-applying gun assembly 600 to apply glue circumferentially to the disc surface of the flap wheel base.

[0028] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
