Description

Technical Field

[0001] This utility model relates to the field of dry laminating machine technology, specifically a material feeding frame for a dry laminating machine. Background Technology

[0002] Dry laminating machines are widely used in packaging, printing, and electronics industries. They are primarily used to bond two or more substrates (such as plastic film, aluminum foil, and paper) together using adhesives to form high-performance composite materials. The working principle involves first uniformly coating the first substrate surface with adhesive (such as polyurethane or acrylate) using a coating roller. The solvent is then evaporated by heating in an oven, allowing the adhesive layer to semi-cur. Finally, under the action of hot press rollers, the adhesive is pressed onto the second substrate, ultimately forming a strong composite product. Dry laminating machines feature high composite strength, good product flatness, and a wide range of applications. They can produce high-performance materials such as food packaging bags, pharmaceutical packaging, and lithium battery aluminum-plastic films. The core components of the equipment include an unwinding device, coating system, oven, laminating rollers, and rewinding device. Modern models are also equipped with automatic tension control, a web guiding system, and intelligent temperature control to ensure stable product quality. Compared to wet lamination or solvent-free lamination, dry laminating machines are more adaptable to different materials and are particularly suitable for applications with strict requirements regarding solvent residue. However, they require an exhaust gas treatment system to meet environmental protection requirements. With the development of intelligent technology, the application of technologies such as high-precision coating, energy-saving drying ovens, and IoT remote monitoring has further improved its efficiency and environmental friendliness, making it one of the key pieces of equipment in the flexible packaging industry.

[0003] The prior art patent application number 201620148375.7, entitled "Feeding Mechanism for Dry Composite Machine," includes a left support, a right support, a left connecting plate, a right connecting plate, a rotating shaft, and a magnetic powder brake. The two ends of the rotating shaft are connected to the left and right supports respectively via bearing seats, and one end of the rotating shaft is connected to the output end of a motor. The middle portions of the left and right connecting plates are respectively connected to the rotating shaft. The two ends of the left connecting plate are respectively provided with left telescopic shafts, which are connected to cylinders fixed on the left connecting plate. The two ends of the right connecting plate are respectively provided with right rotating shafts, which are connected to the magnetic powder brake fixed on the right connecting plate. This device uses two rolls of plastic film to be fixed and alternately fed back and forth, allowing the machine to operate continuously without stopping to reload, saving time and improving work efficiency. However, its fixing structure (such as mechanical bolts or manual locking devices) is cumbersome to adjust and makes it difficult to quickly change feed rollers of different diameters, resulting in increased material change time and affecting production efficiency. On the other hand, the lack of an effective film limiting mechanism makes the plastic film prone to lateral displacement or wrinkling during transport, especially at high speeds, which may affect the subsequent coating and lamination quality due to inaccurate edge alignment. Therefore, a new technical solution needs to be designed to address these issues. Summary of the Invention

[0004] 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.

[0006] Preferably, two mounting brackets are fixedly connected to the outer side of the drive rod. Two cylinders are fixedly connected to one side of one mounting bracket, and two magnetic powder brakes are fixedly connected to one side of the other mounting bracket.

[0010] Preferably, a feeding roller is snapped onto the outer side of the positioning plate, and a second motor is fixedly connected to one side of the transmission chamber. The second motor drives the drive gear, which in turn drives the driven screw to rotate.

Detailed Implementation

[0020] 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.

[0021] Example 1: Please refer to again Figure 1-4 This utility model provides a material feeding frame for a dry compounding machine, including a support 100. A first motor 110 is fixedly connected to one side of the support 100. One end of the power output shaft of the first motor 110 passes through the support 100 and extends to the other side of the support 100. A drive rod 120 is fixedly connected to one end of the power output shaft of the first motor 110. Two mounting brackets 130 are fixedly connected to the outside of the drive rod 120. Two cylinders 140 are fixedly connected to one side of one mounting bracket 130, and two magnetic powder brakes 150 are fixedly connected to one side of the other mounting bracket 130. A connecting bracket 160 is fixedly connected to one end of each cylinder 140 and magnetic powder brake 150. Two limiting rods 170 are fixedly connected to one side of the mounting bracket 130. A limiting plate 171 is fixedly connected to one end of each limiting rod 170. A compression spring 180 is sleeved on the outside of the drive rod 120.

[0022] Specifically, the limiting plate 171 is moved by the compression spring 180 installed on the drive rod 120, so that the limiting plate 171 is in contact with both ends of the plastic film on the feeding roller 230. The plastic film is limited by the limiting plates 171 on both sides, and the limiting rod 170 limits the limiting plate 171 at the same time to prevent the limiting plate 171 from shifting. This can effectively prevent the plastic film from shifting laterally or wrinkling during the conveying process.

[0023] Example 2: Please refer to again Figure 1-4 The inner side of the bracket 100 is provided with a transmission chamber 200. Four gear driven screws 210 are rotatably connected to the inner wall of the transmission chamber 200. A threaded sleeve 211 is screwed to the outer side of the gear driven screw 210. A connecting plate 220 is fixedly connected to one end of the threaded sleeve 211. A positioning plate 221 is fixedly connected to one side of the connecting plate 220. A feeding roller 230 is snapped onto the outer side of the positioning plate 221. A second motor 240 is fixedly connected to one side of the transmission chamber 200. One end of the power output shaft of the second motor 240 passes through the transmission chamber 200 and extends into the inner cavity of the transmission chamber 200. A drive gear 241 is fixedly connected to one end of the power output shaft of the second motor 240. The drive gear 241 meshes with the gear driven screw 210.

[0024] Specifically, by starting the second motor 240, the drive gear 241 is driven to rotate, which in turn drives the four gear driven screws 210 meshing with it to rotate. The threaded sleeve 211 installed on the gear driven screw 210 moves with the rotation of the gear driven screw 210, and the connecting plate 220 installed on the threaded sleeve 211 moves the positioning plate 221 outward, so that the four positioning plates 221 fit against the inner wall of the feeding roller 230, and the positioning plates 221 fix the feeding roller 230. In this way, the positioning mechanism can quickly fix the feeding rollers 230 of different diameters.

[0025] Working principle: The compression spring 180 installed on the drive rod 120 pushes the limiting plate 171 to move, so that the limiting plate 171 is in contact with both ends of the plastic film on the feeding roller 230. The plastic film is limited by the limiting plates 171 on both sides, and the limiting rod 170 limits the limiting plate 171 at the same time, preventing the limiting plate 171 from shifting. This can effectively prevent the plastic film from shifting laterally or wrinkling during the conveying process.

[0026] By starting the second motor 240, the drive gear 241 is driven to rotate, which in turn drives the four gear driven screws 210 meshing with it to rotate. The threaded sleeve 211 installed on the gear driven screw 210 moves with the rotation of the gear driven screw 210, and the connecting plate 220 installed on the threaded sleeve 211 moves the positioning plate 221 outward, so that the four positioning plates 221 fit against the inner wall of the feeding roller 230, and the positioning plates 221 fix the feeding roller 230. In this way, the positioning mechanism can quickly fix the feeding rollers 230 of different diameters.

[0027] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
