Description

Technical Field

[0001] This invention relates to the field of surface forming equipment, and discloses an embossing mechanism and an embossing machine. Background Technology

[0002] In the manufacturing of products such as tissues, leather, and film materials, embossing is often applied to the surface. Current embossing machines typically only have one embossing roller, which has a structure to create patterns on the product. However, this allows for only one type of pattern to be created. Changing the embossed pattern requires disassembling and replacing the roller, necessitating machine downtime. This process is complex, cumbersome, and labor-intensive. Therefore, there is an urgent need for an embossing mechanism that allows for easy switching between different patterns to improve production efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide an embossing mechanism and an embossing machine to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0004] According to a first aspect of the present invention, an embossing mechanism includes: a frame; an embossing unit including an upper embossing roller, a lower embossing roller, a transmission arm, a transition roller, a movable part, and a swing drive member. The upper embossing roller and the lower embossing roller are rotatably connected to the frame at intervals in a vertical direction. The transition roller is rotatably connected to the frame and located between the upper embossing roller and the lower embossing roller. The swing drive member is connected to the frame and is throttle-connected to one end of the transmission arm. The other end of the transmission arm is rotatably connected to the frame. The movable part is disposed on the transmission arm and has a rotatable pressure roller. The swing drive member can drive the transmission arm to rotate, causing the pressure roller in the movable part to move upward toward the upper embossing roller or downward toward the lower embossing roller.

[0005] This technical solution has at least the following beneficial effects: the upper and lower embossing rollers have different patterns. The strip material to be embossed is first fed to the upper or lower embossing roller, then passes around the transition roller, and is then fed to the lower or upper embossing roller before being led out to the next station. When the strip material needs to be pressed to form the required pattern, the oscillating drive component drives the transmission arm to rotate, causing the pressure roller on the transmission arm to move upward toward the upper embossing roller or downward toward the lower embossing roller, pressing the strip material onto the upper or lower embossing roller for embossing. The connection point of the oscillating drive component transmitting power to the transmission arm and the rotation fulcrum of the transmission arm form a long lever arm. The movable part is located at... The position of the transmission arm and its rotation fulcrum form a short lever arm, making the transmission arm a force-saving lever. When the oscillating drive component drives the transmission arm to rotate, the oscillating drive component only needs a small driving force to drive the transmission arm to rotate. This helps to ensure the stability when moving the pressure roller closer to the strip for embossing. Thus, when it is necessary to change the embossing pattern of the strip, the pressure roller can be moved directly to the upper or lower embossing roller without disassembly or replacement. This effectively improves the flexibility and efficiency of embossing. Furthermore, the oscillating drive component drives the pressure roller to move through the force-saving lever, reducing energy consumption and improving the stability and quality of embossing.

[0006] According to some embodiments of the present invention, the movable part includes a lifting frame, an adjusting seat, and a connecting rod. The lifting frame is slidably connected to the frame in the vertical direction. The adjusting seat is disposed inside the lifting frame. The pressure roller is rotatably connected to the adjusting seat. The adjusting seat is provided with a slot extending in the horizontal direction. The connecting rod passes through the slot and is connected to the transmission arm.

[0007] According to some embodiments of the present invention, the frame is provided with an opening, and two first side wings are provided at intervals along the front-back direction on one side of the frame located at the opening. One side of the lifting frame extends into the space between the two first side wings, and two second side wings are provided at intervals along the front-back direction on the other side of the lifting frame. The two second side wings abut against the front and rear sides of the frame respectively.

[0008] According to some embodiments of the present invention, the embossing unit further includes a side embossing roller, which is located on the side of the pressure roller away from the lifting frame. Transition rollers are respectively arranged between the upper embossing roller and the side embossing roller, and between the lower embossing roller and the side embossing roller. A translation drive is connected inside the lifting frame. The translation drive is tractively connected to the adjusting seat. The adjusting seat is slidably connected inside the lifting frame. The translation drive can drive the adjusting seat to slide closer to or away from the side embossing roller.

[0009] According to some embodiments of the present invention, the lifting frame is provided with an installation port, the lifting frame is provided with two third side wings spaced apart in the front-back direction on the upper side of the installation port, the lifting frame is provided with two fourth side wings spaced apart in the front-back direction on the lower side of the installation port, the top side of the adjusting seat has an upper protrusion extending between the two third side wings, and the bottom side of the adjusting seat has a lower protrusion extending between the two fourth side wings.

[0010] According to some embodiments of the present invention, the embossing unit further includes a motor, an upper drive wheel connected to the end of the upper embossing roller, a lower drive wheel connected to the end of the lower embossing roller, and a side embossing wheel connected to the end of the side embossing roller. A drive belt drives the upper drive wheel, the lower drive wheel and the side embossing wheel. The motor drives the upper embossing roller, the lower embossing roller or the side embossing roller.

[0011] According to some embodiments of the present invention, the frame is provided with a tensioning seat that can move toward or away from the drive belt, the tensioning seat is rotatably connected to a tensioning wheel, and the tensioning wheel abuts against the drive belt.

[0012] According to some embodiments of the present invention, a guide roller is rotatably connected to the top side of the frame.

[0013] According to some embodiments of the present invention, multiple embossing units are provided on the frame.

[0014] An embossing machine according to a second aspect of the present invention includes the embossing mechanism described above.

[0015] This technical solution has at least the following beneficial effects: In this embossing machine, when it is necessary to change the embossing pattern of the strip, the pressure roller can be brought close to the upper or lower embossing roller directly without disassembly or replacement, which effectively improves the flexibility and efficiency of embossing. Furthermore, the oscillating drive component drives the pressure roller to move through a force-saving lever, which reduces working energy consumption and helps to improve the stability and quality of embossing.

[0028] Reference Figure 1 and Figure 2 According to a first aspect embodiment of the present invention, an embossing mechanism includes a frame 100 and an embossing unit. The embossing unit includes an upper embossing roller 221, a lower embossing roller 222, a transmission arm 226, a transition roller 224, a movable part, and a swing drive member. The upper embossing roller 221 and the lower embossing roller 222 are rotatably connected to the frame 100 at intervals in the vertical direction. The transition roller 224 is rotatably connected to the frame 100 and located between the upper embossing roller 221 and the lower embossing roller 222. Naturally, the rotation axes of the upper embossing roller 221, the lower embossing roller 222, and the transition roller 224 are all parallel to each other. The swing drive member is connected to the frame 100. The swing drive is connected to one end of the transmission arm 226, and the other end of the transmission arm 226 is rotatably connected to the frame 100. The movable part is disposed on the transmission arm 226. The movable part has a rotatable pressure roller 211. The swing drive can drive the transmission arm 226 to rotate, and cause the pressure roller 211 in the movable part to move upward toward the upper embossing roller 221 or downward toward the lower embossing roller 222. The swing drive can be a rotary drive source, such as a rotary valve or motor, or a linear drive source such as a cylinder, electric screw or hydraulic cylinder. The output end of the swing drive is rotatably connected to the end of the transmission arm 226.

[0029] As described above, the upper embossing roller 221 and the lower embossing roller 222 have different patterns. The strip material to be embossed is first fed to the upper embossing roller 221 or the lower embossing roller 222, then passes around the transition roller 224, and is then fed to the lower embossing roller 222 or the upper embossing roller 221 before being led out to the next station. When the strip material needs to be pressed to form the required pattern, the oscillating drive drives the transmission arm 226 to rotate, causing the pressure roller 211 on the transmission arm 226 to move upward toward the upper embossing roller 221 or downward toward the lower embossing roller 222, pressing the strip material onto the upper embossing roller 221 or the lower embossing roller 222 for embossing. The connection point of the oscillating drive transmitting power to the transmission arm 226 and the rotation fulcrum of the transmission arm 226 form a long lever arm. The position of the drive arm 226 forms a short lever arm with the rotation fulcrum of the drive arm 226, making the drive arm 226 a force-saving lever. When the swing drive component drives the drive arm 226 to rotate, the swing drive component only needs a small driving force to drive the drive arm 226 to rotate. This helps to ensure the stability when moving the pressure roller 211 closer to the strip for embossing. Thus, when it is necessary to change the embossing pattern of the strip, the pressure roller 211 can be moved directly to the upper embossing roller 221 or the lower embossing roller 222 without disassembly or replacement. This effectively improves the flexibility and efficiency of embossing. Furthermore, the swing drive component drives the pressure roller 211 to move through the force-saving lever, reducing working energy consumption and improving the stability and quality of embossing.

[0030] The movable part is mounted on the transmission arm 226 and can rotate upwards towards the upper embossing roller 221 or downwards towards the lower embossing roller 222 in a swinging manner as the transmission arm 226 rotates. In this embodiment, it can move the pressure roller 211 in a vertically moving manner. Specifically, the movable part includes a lifting frame 227, an adjusting seat 210, and a connecting rod. The lifting frame 227 is slidably connected to the frame 100 in the vertical direction. The adjusting seat 210 is disposed in the lifting frame 227. The pressure roller 211 is rotatably connected to the adjusting seat 210. The adjusting seat 210 is provided with a slot 213 extending in the left-right direction. The connecting rod passes through the slot 213 and is connected to the transmission arm 226. A connecting rod is threaded through the transmission arm 226 and passes through the slot 213 on the adjusting seat 210, thereby giving the adjusting seat 210 and the transmission arm 226 a degree of freedom to move in the left and right directions. When the transmission arm 226 rotates upward, it can drive the adjusting seat 210 to move upward, and cause the lifting frame 227 to move upward within the frame 100. Conversely, when the transmission arm 226 rotates downward, it can drive the adjusting seat 210 to move downward, and cause the lifting frame 227 to move downward within the frame 100.

[0031] As a specific embodiment in which the lifting frame 227 is slidably connected to the frame 100 in the vertical direction, such as Figure 3 As shown, in this embodiment, the frame 100 is provided with an opening 150. Two first side wings 110 are provided at intervals along the front-back direction on one side of the frame 100 located at the opening 150. One side of the lifting frame 227 extends into the space between the two first side wings 110. Two second side wings 120 are provided at intervals along the front-back direction on the other side of the lifting frame 227. The two second side wings 120 abut against the front and rear sides of the frame 100 respectively. Two first side wings 110 on one side of the frame 100 located at the opening 150 form a sliding groove extending in the vertical direction. One side of the lifting frame 227 is inserted into the sliding groove to achieve a sliding connection with the frame 100. On the other side of the lifting frame 227, two second side wings 120 form a sliding groove structure, which can be inserted into the sliding groove structure. Thus, during installation, the lifting frame 227 is first inserted into the opening 150, and then the sliding limit is formed by installing the first side wings 110 and the second side wings 120 to achieve a sliding connection between the two sides of the lifting frame 227 and the two sides of the opening 150.

[0032] To further enrich the selectable embossing styles, in this embodiment, the embossing unit also includes a side embossing roller 223. The side embossing roller 223 is located on the side of the pressure roller 211 away from the lifting frame 227. Transition rollers 224 are respectively provided between the upper embossing roller 221 and the side embossing roller 223, and between the lower embossing roller 222 and the side embossing roller 223. A translation drive 228 is connected inside the lifting frame 227. The translation drive 228 is driven to the adjusting seat 210. The adjusting seat 210 is slidably connected inside the lifting frame 227. The translation drive 228 can drive the adjusting seat 210 to slide closer to or away from the side embossing roller 223. A side embossing roller 223 is provided on the side of the pressure roller 211. The side embossing roller 223 can be configured with different patterns. When embossing is performed, if the side embossing roller 223 is used to press the pattern, the translation drive 228 drives the adjusting seat 210 to approach the side embossing roller 223, so that the pressure roller 211 presses the strip against the side embossing roller 223 to achieve embossing. After completion, the translation drive 228 drives the adjusting seat 210 to slide away from the side embossing roller 223.

[0033] As a specific embodiment in which the adjusting seat 210 is slidably connected to the lifting frame 227 in the left-right direction, the lifting frame 227 is provided with an installation port 229. The lifting frame 227 is provided with two third side wings 130 spaced apart in the front-back direction on the upper side of the installation port 229, and two fourth side wings 140 spaced apart in the front-back direction on the lower side of the lifting frame 227. The top side of the adjusting seat 210 has an upper protrusion extending between the two third side wings 130, and the bottom side of the adjusting seat 210 has a lower protrusion 212 extending between the two fourth side wings 140. The two third side wings 130 and the two fourth side wings 140 respectively form groove structures on the upper and lower sides of the mounting port 229 of the lifting frame 227. The upper protrusion and lower protrusion 212 formed by the adjusting seat 210 are respectively inserted into the groove structure, which can realize the sliding connection between the adjusting seat 210 and the lifting frame 227. Thus, when installing the adjusting seat 210, the adjusting seat 210 can be directly installed into the mounting port 229 first, and then the third side wings 130 and the fourth side wings 140 are respectively installed on the upper and lower sides of the lifting frame 227 at the mounting port 229. This improves the convenience of the overall installation and facilitates the subsequent disassembly and maintenance of the pressure roller 211.

[0034] Naturally, in order to drive the strip material to move, power needs to be provided to the embossing roller or pressure roller 211. For example, a rotary drive source can be directly provided on the adjusting seat 210, which drives the motor 231 to rotate. In this embodiment, power is provided to the upper embossing roller 221, the lower embossing roller 222, or the side embossing roller 223. Specifically, the embossing unit also includes a motor 231, an upper transmission wheel 232 connected to the end of the upper embossing roller 221, a lower transmission wheel 234 connected to the end of the lower embossing roller 222, and a side embossing roller 235 connected to the end of the side embossing roller 223. A transmission belt is connected between the upper transmission wheel 232, the lower transmission wheel 234, and the side embossing roller 235. The motor 231 is connected to the upper embossing roller 221, the lower embossing roller 222, or the side embossing roller 223. The motor 231 can first transmit power to one of the upper embossing roller 221, lower embossing roller 222, or side embossing roller 223, so that one of the upper embossing roller 221, lower embossing roller 222, or side embossing roller 223 rotates. Then, the upper drive wheel 232, lower drive wheel 234, side embossing roller 235, and drive belt are used to transmit power to each other, so that the upper embossing roller 221, lower embossing roller 222, and side embossing roller 223 rotate synchronously, thereby realizing the conveying of the strip material.

[0035] To prevent the drive belt from slipping during power transmission, in this embodiment, the frame 100 is equipped with a tensioning seat that can move towards or away from the drive belt. For example, the tensioning seat has a slotted groove. A positioning screw passes through the slot, allowing the tensioning seat to move along the length of the slot. The tensioning wheel 236 applies pressure to the drive belt, and the positioning screw then secures the tensioning seat to the frame 100. The tensioning seat is rotatably connected to the tensioning wheel 236, which abuts against the drive belt. By applying pressure to the drive belt through the tensioning wheel 236, the drive belt is tensioned, ensuring the stability of power transmission.

[0036] In some embodiments, a guide roller 300 is rotatably connected to the top side of the frame 100. The strip material to be embossed is first fed from the outside and passes around the guide roller 300, where the guide roller 300 guides the strip material, and then feeds it to the upper embossing roller 221 or the lower embossing roller 222.

[0037] One embossing unit can perform embossing processing on one strip. To improve embossing efficiency, in this embodiment, multiple embossing units are provided on the frame 100. Multiple embossing units can simultaneously perform embossing processing on multiple strips, improving overall production efficiency.

[0038] An embossing machine according to a second aspect of the present invention includes the embossing mechanism described above.

[0039] In this embossing machine, when it is necessary to change the embossing pattern of the strip, the pressure roller 211 can be brought close to the upper embossing roller 221 or the lower embossing roller 222 directly without disassembly or replacement. This effectively improves the flexibility and efficiency of the embossing process. Furthermore, the oscillating drive component drives the pressure roller 211 to move through a force-saving lever, reducing energy consumption and improving the stability and quality of the embossing process.

[0040] The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the embodiments described.
