Description

Technical Field

[0001] This utility model belongs to the field of automated production, and in particular relates to a solid adhesive cutting, coating and conveying mechanism. Background Technology

[0002] Solid adhesives are adhesives that remain solid at room temperature and pressure. They are commonly found in daily life and industrial production. Currently, in the production process of solid adhesives, apart from the mixing process which has been automated, many subsequent key processes, such as cutting, laminating, coating, and transportation, still mainly rely on manual operation.

[0003] However, solid adhesives are semi-solid after extrusion and have extremely high viscosity, easily adhering to cutting tools and contacting materials, leading to difficulties in automatic cutting and a high defect rate. During conveying, a bottom film is usually applied to prevent adhesion, but in automated processes, the alignment and bonding stability between the film and the adhesive is difficult to control precisely, easily resulting in misalignment, wrinkling, or film detachment. Furthermore, the production of solid adhesives is generally a continuous process, requiring high levels of consistency throughout the entire process, precise timing matching between processes, and intelligent management, which increases production costs for automation upgrades. Therefore, there is an urgent need for an automation solution that can effectively address the above-mentioned technological challenges while being cost-effective, easy to implement, and compact in structure.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0027] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0028] Please see Figure 1 and Figure 5 This utility model provides a solid adhesive cutting and coating conveying mechanism, comprising:

[0029] The film feeding mechanism 1 is used to place and transport the film, including a placement frame 11 on which a mounting shaft 12 for mounting the film roll is rotatably arranged, and two support wheels 13 are symmetrically mounted on its side, which are in extrusion contact with the film roll mounted on the mounting shaft 12.

[0030] Conveying module 2, located on one side of film feeding mechanism 1, includes:

[0031] A support frame 21, on the side of which a motor 22 is fixedly mounted;

[0032] The belt conveyor 24 is mounted on the support frame 21, and its drive shaft is connected to the power output end of the motor 22 via a reducer 23.

[0033] The film cutting and coating mechanism 3 is installed on the support frame 21 and located above one end of the belt conveyor 24. It includes two parallel film feeding units 31 for conveying the coating to the belt conveyor 24. A film cutting unit 32 is also provided between the two film feeding units 31 for cutting the coating.

[0034] The adhesive cutting structure 4 is located on one side of the film cutting unit 32 and is used to cut the extruded solid adhesive. It includes a fixing frame 41, which is vertically arranged and connected to the output port of an external extruder. Multiple cylinders 42 are fixedly installed on it. The telescopic ends of the cylinders 42 are fixedly connected to the blade holder 43. A cutter 44 is fixedly installed on the blade holder 43 close to the side of the fixing frame 41.

[0035] In practical application, the film roll is rotated and mounted on the mounting shaft 12. The film is manually pulled to make it rotate with the belt conveyor 24. The external extruder dispenses glue. After the photoelectric sensor detects the glue, the motor 22 is started, and the belt conveyor 24 enters a uniform speed operation state. Under the action of gravity, the solid glue automatically falls onto the belt conveyor 24. After the film is transported to the appropriate position by the belt conveyor 24, the glue cutting structure 4 is activated. The cylinder 42 drives the cutter 43 to cut the solid glue. At the same time, the film cutting unit 32 cuts the film synchronously. After the film is cut, the belt conveyor 24 accelerates. When the film moves to the bottom of the solid glue cutting nozzle, it returns to the original speed to replenish the film in time and ensure that the cut glue is transported to the rear end of the belt conveyor 24, thus completing one processing cycle.

[0036] This embodiment achieves highly efficient automation of the entire processing cycle through the linkage control of various components, enabling the entire process from film conveying, gluing to cutting. This significantly reduces manual intervention and single-piece operation time, facilitating continuous mass production and increasing productivity. Furthermore, through the coordinated work of the glue cutting structure 4 and the film cutting and coating mechanism 3, the film is simultaneously cut while the solid glue is being cut, ensuring that the bottom of each piece of glue is protected by a film and does not directly contact the conveying mechanism. This effectively avoids the problem of solid glue being too sticky to facilitate automated production.

[0037] In one embodiment, a position detection sensor and a water circulation mechanism can be installed on the cutting adhesive structure 4 to detect the position of the coating and solid adhesive in real time, thereby outputting a signal to control the operation of the equipment. The water circulation structure cools down the cutting adhesive structure 4, thereby indirectly cooling down the high-temperature solid adhesive, thereby reducing the viscosity of the solid adhesive and reducing sticking to the knife.

[0038] Please see Figure 1 , Figure 4 and Figure 5 In a preferred embodiment of the present invention, the film feeding mechanism 1 further includes a magnetic powder brake 14, which is fixedly installed on the side of the placement frame 11 and connected to the shaft end of the mounting shaft 12.

[0039] In practical applications, this embodiment uses a magnetic powder brake 14 integrated into the control system to control the rotation of the mounting shaft 12. By precisely controlling its braking torque, the tension of the coating roll remains stable throughout the entire process of starting, running at a constant speed, and decelerating to a stop, thereby ensuring product quality and preventing the material from wrinkling or breaking.

[0040] Please see Figure 3 In another preferred embodiment of the present invention, the film feeding unit 31 includes a mounting frame 311 and a unit 312. The mounting frame 311 is configured as an inverted "U" shape and is fixedly mounted on the support frame 21. The unit 312 is movably mounted in the mounting frame 311 through a shaft end.

[0041] Furthermore, the mounting bracket 311 is also fixedly provided with movable grooves 3111 at both ends corresponding to the shaft ends of the unit 312. A limiting rod 313 is movably arranged in the groove. The upper end of the limiting rod 313 movably passes through the mounting bracket 311 and extends to the outside of the mounting bracket 311, and the lower end movably passes through the shaft end of the unit 312. A limiting spring 314 is movably sleeved on the limiting spring 314. The two ends of the limiting spring 314 are respectively pressed and contacted with the top of the mounting bracket 311 and the side of the unit 312.

[0042] In practical application, the two units 312 are installed in the mounting frame 311 under the limiting action of the limiting rod 313, and in conjunction with the limiting spring 314, elastic compression is achieved on the unit 312, so that the unit 312 is pressed into contact with the belt on the surface of the belt conveyor 24, thereby assisting the film feeding mechanism 1 in conveying the film.

[0043] Please see Figure 2 and Figure 3 In another preferred embodiment of the present invention, the film cutting unit 32 includes a guide rail 321 horizontally fixedly installed on the side of the film feeding unit 31, on which a slider 322 is slidably fitted. A knife holder 323 is fixedly installed at the bottom of the slider 322, and a film cutting knife 324 is fixedly installed on the knife holder 323.

[0044] In practical application, the slider 322 moves horizontally on the guide rail 321, which drives the knife holder 323 mounted on the slider 322 to move, thereby cutting the film through the film cutting knife 324.

[0045] In one embodiment, the driving movement of the slider 322 can be set to various methods, such as cylinder extension drive, motor synchronous belt drive, or lead screw and nut drive. As long as the slider 322 is driven to move, this embodiment will not impose any additional limitations.

[0046] Please see Figure 2 and Figure 3 As another preferred embodiment of the present invention, the cutting adhesive structure 4 further includes a protective frame 45, which is configured as a frame structure, fitted at the lower end of the fixing frame 41 and fixedly connected to the side of the adjacent mounting frame 311.

[0047] In practical applications, the protective frame 45 in this embodiment provides auxiliary support for the fixing frame 41, improving structural stability while also acting as a barrier to protect the extruded solid adhesive, preventing environmental dust from affecting the quality of the solid adhesive.

[0048] Please see Figure 1 , Figure 2 and Figure 5 As another preferred embodiment of the present invention, it also includes a film stretching mechanism 5, including a support frame 51, which is fixedly installed on the support frame 21 and located on one side of the cutting adhesive structure 4. Multiple casters 52 are fixedly installed on it. The casters 52 make contact with the film extrusion to achieve tension and press on the belt conveyor 24.

[0049] In practical applications, the film-pulling mechanism 5 is used to tension and press the film onto the belt conveyor 24, thereby providing auxiliary traction for the film and solid adhesive, ensuring stable conveying and high-quality film bonding.
