Description

Technical Field

[0001] The present application relates to the technical field of strapping tape embossing, and in particular to an embossing machine unit suitable for embossing multiple tapes. Background Art

[0002] Strapping tape is widely used in logistics, transportation and other fields. Its surface quality and aesthetics have an important impact on the packaging effect and market competitiveness of the product. In the traditional strapping tape production process, a group of single rollers (one roller on the top and one roller on the bottom) are usually used to emboss the strapping tape surface. Obviously, the length of a single roller is limited, and the number of strapping tapes that can be rolled at the same time is relatively small, which is not conducive to embossing multiple strapping tapes in parallel and at the same time, so the production efficiency is relatively low. For example, the Chinese invention patent with publication number CN119189281A, a strapping tape surface embossing production device and strapping tape production line, has only one group of upper and lower rollers in the strapping tape pressing machine, and the number of strapping tapes that can be embossed at one time is relatively small.

[0003] On this basis, a solution that can be easily thought of is to lengthen the extension length of a single roller so that multiple strapping tapes can be rolled at the same time. However, extending the length of a single roller will make the overhang of the roller too long, and the overhanging end of the roller is prone to stress deformation, leading to a series of problems, such as: 1. Uneven embossing; 2. Pulling the lifting mechanism to cause its deformation; 3. If the tape breaks during the production process, it will get stuck on the long embossing roller, which will cause all the tapes on the roller surface to break, resulting in serious quality and equipment accidents.

[0004] Therefore, the prior art lacks a device that can realize simultaneous rolling of multiple belts while preventing excessive overhang of the roller from causing equipment deformation, uneven embossing, and belt breakage that causes all belts on the roller surface to break. Summary of the invention

[0005] In view of the above-mentioned shortcomings of the prior art, the present application provides an embossing machine unit suitable for multi-belt embossing, which is applied to the field of strapping tape embossing technology. It has the advantages of effectively avoiding equipment deformation caused by excessive overhang of the embossing roller, uneven embossing, and the problem of all tapes on the roller surface being broken when the tape breaks, and can improve the efficiency and quality of multi-belt embossing production.

[0006] In a first aspect, an embossing machine unit adapted for multi-belt embossing comprises at least: An embossing machine frame, and a pressing roller arranged on the embossing machine frame; The rollers of the roller press machine at least include a front roller device and a rear roller device, and the front roller device and the rear roller device are arranged at intervals along the conveying direction of the strapping belt; The front pressing roller device and the rear pressing roller device each include at least two rollers, the two rollers on the same pressing roller device are arranged at intervals in the width direction of the strapping tape, and the rollers on the front pressing roller device and the rear pressing roller device are arranged alternately, so that the staggered rollers emboss all the strapping tapes conveyed in parallel in the width direction.

[0007] The present application provides an embossing machine unit adapted for multi-belt embossing, which aims to solve the problem of low efficiency and easy deformation of single-roller embossing units in the prior art. By adopting front and rear roller devices instead of the traditional single roller. Each roller device (front roller device and rear roller device) includes at least two rollers, which are arranged at intervals in the width direction of the strapping tape, which means that multiple parallel strapping tapes can be embossed at the same time, which can greatly improve the embossing efficiency of the strapping tape. And the setting of two rollers reduces the risk of deformation caused by lengthening a single roller. More importantly, the rollers on the front roller device and the rear roller device are staggered. This staggered setting makes the rollers of the front roller device and the rear roller device complement each other in the width direction, and together cover the width of all strapping tapes transported in parallel, which can improve the embossing quality of the strapping tape. At the same time, multiple short rollers cooperate to emboss, and when a strap breaks, only the strapping tape under one group of rollers will break, and the strapping tape on the entire roller surface will not break. Therefore, the embossing machine unit has effectively solved the limitations of the single roller embossing unit in the prior art in the application of multi-belt embossing by cleverly designing the front and rear roller devices and the staggered arrangement of multiple rollers, and has achieved efficient and stable multi-belt embossing. It has the beneficial effect of effectively avoiding the equipment deformation caused by the excessive overhang of the roller, uneven embossing, and the problem of all belts on the roller surface being broken when the belt breaks, and can improve the efficiency and quality of multi-belt embossing production.

[0008] Furthermore, in the front pressure roller device and the rear pressure roller device, adjacent end surfaces of the two rollers arranged alternately are flush.

[0009] The present application provides an embossing machine unit suitable for embossing multiple straps. The structure in which the adjacent end faces of the staggered rollers are flush allows the strapping strap to pass through the junction of the front pressing roller device and the rear pressing roller device. The force exerted by the rollers on the strapping strap is uniform and continuous, thereby avoiding problems such as uneven embossing depth and intermittent embossing, thereby ensuring the uniformity of the embossing quality of multiple strapping straps.

[0010] Furthermore, it also includes a lifting device, and the lifting device at least includes a first lifting device and a second lifting device; The first lifting device is connected to each of the rollers in the front pressure roller device, and is used to drive the front pressure roller device to move up and down; The second lifting device is connected to each of the rollers in the rear pressure roller device and is used to drive the rear pressure roller device to move up and down.

[0011] The present application provides an embossing machine unit suitable for multi-belt embossing. The first lifting device and the second lifting device respectively drive the front pressing roller device and the rear pressing roller device to move up and down, thereby adjusting the gap between the roller and the strapping tape, thereby adapting to strapping tapes of different thicknesses, or adjusting the pressure of the pressing roller of the pressing roller machine according to the embossing requirements, thereby improving the adaptability of the embossing machine unit.

[0012] Further, the first lifting device at least includes a first mounting plate arranged horizontally; One end of the first mounting plate is fixed to the embossing machine frame, and the first mounting plate and the embossing machine frame are fixed in a right angle structure; The upper end surface of the first mounting plate is used for mounting the first driving device, and the lower end surface is used for mounting the front pressure roller device. The first driving device is connected to each of the rollers in the front pressure roller device.

[0013] The present application provides an embossing machine unit suitable for multi-belt embossing. The first mounting plate is horizontally arranged and fixed at right angles to the embossing machine frame, which can provide a stable mounting platform for the first driving device and the front roller device, ensuring that the first driving device can stably and reliably drive the front roller device to move up and down; and the upper end surface of the first mounting plate is used to install the first driving device, and the lower end surface is used to install the front roller device, so that the layout structure of the first driving device and the front roller device is compact, saving space, and making the lifting device structure more reasonable. The first driving device is connected to each roller in the front roller device, and each roller can be driven separately, so that the lifting and lowering of each roller is more precise and the embossing effect is better.

[0014] Further, the second lifting device at least includes a second mounting plate arranged horizontally; One end of the second mounting plate is fixed to the embossing machine frame, and the second mounting plate and the embossing machine frame are fixed in a right angle structure; The upper end surface of the second mounting plate is used for mounting the second driving device, and the lower end surface is used for mounting the rear pressure roller device. The second driving device is connected to each of the rollers in the rear pressure roller device.

[0015] Furthermore, mounting side plates are fixed on both sides of the first mounting plate and the second mounting plate, and the mounting side plates are fixed to the embossing machine frame and form a supporting frame structure with the first mounting plate and the second mounting plate respectively to support the components installed on the first mounting plate and the second mounting plate respectively.

[0016] Furthermore, the first driving device and the second driving device each include at least two driving parts, and each driving part is correspondingly connected to one of the rollers to drive the rollers to move up and down.

[0017] Furthermore, the driving part at least includes a hand grip, a first screw connected to the hand grip, a steering gear connected to the first screw, and a second screw connected to the steering gear and the roller respectively; The first screw rod is provided with a rack meshing with the steering gear, one end of the second screw rod is inserted into the center of the gear shaft of the steering gear, and the other end is provided with a rack connected to the roller; the second screw rod rotates coaxially with the steering gear; The first screw rod cooperates with the steering gear to convert the force of the hand grip rotating around the axial direction of the first screw rod into the force of the axial rotation around the steering gear, and the second screw rod transmits the force of the axial rotation around the steering gear to the roller, so that the roller rises or falls along the rack spiral on the second screw rod.

[0018] Furthermore, a second screw rod is respectively provided at both ends of each roller, and each second screw rod corresponds to a steering gear.

[0019] Furthermore, the steering gear corresponding to each roller is driven by one of the first screw rods and one of the hand grips.

[0020] Beneficial effects: The present application provides an embossing machine unit adapted for multi-belt embossing, which adopts front and rear roller devices instead of the traditional single roller. Each roller device (front roller device and rear roller device) includes at least two rollers, which are arranged at intervals in the width direction of the strapping tape, which means that multiple parallel strapping tapes can be embossed at the same time, which can greatly improve the efficiency of strapping tape embossing. And the setting of two rollers reduces the risk of deformation caused by lengthening a single roller. More importantly, the rollers on the front roller device and the rear roller device are staggered. This staggered setting makes the rollers of the front roller device and the rear roller device complement each other in the width direction, and together cover the width of all strapping tapes transported in parallel, which can improve the embossing quality of the strapping tape. At the same time, multiple short rollers cooperate for embossing. When a strap breaks, only the strapping tape under one group of rollers will break, and the strapping tape on the entire roller surface will not break. Therefore, the embossing machine unit has effectively solved the limitations of the single roller embossing unit in the prior art in the application of multi-belt embossing by cleverly designing the front and rear roller devices and the staggered arrangement of multiple rollers, and has achieved efficient and stable multi-belt embossing. It has the beneficial effect of effectively avoiding the equipment deformation caused by the excessive overhang of the roller, uneven embossing, and the problem of all belts on the roller surface being broken when the belt breaks, and can improve the efficiency and quality of multi-belt embossing production.

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application usually described and marked in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.

[0027] It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. At the same time, in the description of this application, the terms "first, second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0028] The prior art lacks a device that can realize simultaneous rolling of multiple belts and prevent the overhang of the rollers from causing deformation of the equipment and uneven embossing. In order to solve this problem, the present application proposes an embossing machine unit suitable for multi-belt embossing, and the following disclosure provides many different embodiments or examples to achieve the purpose of the present invention.

[0029] Please refer to Figures 1 to 4 , an embossing machine unit suitable for multi-belt embossing, comprising at least: An embossing machine frame 1, and a pressing roller 2 arranged on the embossing machine frame 1; The roller 2 of the roller press machine at least comprises a front roller device 21 and a rear roller device 22, and the front roller device 21 and the rear roller device 22 are arranged at intervals along the conveying direction of the strapping belt; The front pressing roller device 21 and the rear pressing roller device 22 each include at least two rollers 23. The two rollers 23 on the same pressing roller device are arranged at intervals in the width direction of the strapping tape, and the rollers 23 on the front pressing roller device 21 and the rear pressing roller device 22 are arranged alternately, so that the staggered rollers 23 can emboss all the strapping tapes conveyed in parallel in the width direction.

[0030] The embossing machine frame 1 serves as a supporting structure for the entire embossing machine unit, thereby ensuring the stability and reliability of the unit.

[0031] The roller 2 of the roller press machine includes a front roller device 21 and a rear roller device 22, which decomposes a traditional single roller into two independent front and rear devices, and the front roller device 21 and the rear roller device 22 each include at least two rollers 23, which shortens the length of a single roller 23, reduces the risk of deformation caused by the roller 23 being too long, and ensures the uniformity of embossing. At the same time, the arrangement of the front and rear devices also provides a structural basis for staggered arrangement of the rollers 23.

[0032] The spacing along the strapping belt conveying direction ensures that the strapping belt can pass through the front pressing roller device 21 and the rear pressing roller device 22 in sequence to achieve staged embossing. The front pressing roller device 21 and the rear pressing roller device 22 each include at least two rollers 23, and the two rollers 23 are spaced apart in the width direction so that each pressing roller device can cover a strapping belt of a certain width, and can roll multiple strapping belts in parallel at the same time.

[0033] The staggered arrangement of multiple rollers 23 means that the rollers 23 of the front pressing roller device 21 and the rear pressing roller device 22 are staggered, which effectively covers the total width of multiple strapping tapes without increasing the length of a single roller 23, solves the problem of limited length of a single roller, ensures that all strapping tapes conveyed in parallel are fully embossed, improves the embossing efficiency and quality, and avoids deformation and uneven embossing caused by excessive length of a single roller.

[0034] In the prior art, the equipment using a single extended roller for embossing will get stuck when the strapping tape breaks, causing the strapping tape on the entire roller surface to break, causing serious production accidents. However, the roller 2 of the roller press in the present application is composed of multiple groups of short rollers 23. When the strapping tape breaks, only one group will get stuck, and the strapping tape under the other rollers 23 can still be embossed normally, which greatly improves production efficiency and production quality.

[0035] In some specific implementations, the embossing machine frame 1 can be formed by welding metal profiles to provide sufficient strength and rigidity.

[0036] The pressing roller 2 of the pressing roller machine can be composed of parts such as a roller wheel 23 and a roller shaft, and the surface of the roller wheel 23 can be processed into different patterns according to the embossing requirements.

[0037] The front pressing roller device 21 and the rear pressing roller device 22 can be fixed on the embossing machine frame 1 respectively, and a certain distance is maintained between the two so that the strapping tape can pass smoothly.

[0038] The specific number of rollers 23 arranged at intervals in the width direction can be adjusted according to the number and width of strapping tapes to be embossed. For example, if thirty strapping tapes are to be embossed at the same time, two or three rollers 23 can be arranged in each pressing roller device. The staggered arrangement of multiple rollers 23 can be achieved by adjusting the installation positions of the rollers 23 on the front and rear pressing roller devices 22, so that the rollers 23 on the front pressing roller device 21 and the rollers 23 on the rear pressing roller device 22 are staggered in the width direction.

[0039] Specifically, when multiple strapping tapes are transported in parallel through the embossing machine unit, they first enter the front pressing roller device 21, and the multiple rollers 23 on the front pressing roller device 21 emboss part of the strapping tape. Subsequently, the strapping tape continues to be transported to the rear pressing roller device 22, and the rollers 23 staggered on the rear pressing roller device 22 emboss the portion that has not been embossed by the rollers 23 of the front pressing roller device 21. Therefore, since the rollers 23 of the front and rear pressing roller devices 22 are staggered, it can be ensured that all strapping tapes are covered and embossed by the rollers 23 in the width direction of the strapping tape, thereby achieving simultaneous embossing of multiple strapping tapes. By using the front and rear pressing roller devices 22 instead of the traditional single pressing roller, each pressing roller device includes at least two rollers 23, which are arranged at intervals in the width direction of the strapping tape, and can emboss multiple parallel strapping tapes at the same time. The rollers 23 on the front roller device 21 and the rear roller device 22 are staggered, and this staggered arrangement makes the rollers 23 of the front roller device 21 and the rollers 23 of the rear roller device 22 complement each other in the width direction, and together cover the width of all the strapping tapes transported in parallel. Through the above structure, while ensuring the embossing effect, the embossing efficiency is improved, and the technical problems that the single-roller embossing unit in the prior art cannot adapt to the simultaneous embossing of multiple tapes, and the lengthening of the single roller easily leads to deformation of the roller and uneven embossing are solved.

[0040] Among them, in some preferred embodiments, the elongation of each roller 23 in the width direction does not exceed a set value, which is a value set in advance according to process requirements to ensure that each roller 23 will not affect the operation of the equipment due to excessive overhang.

[0041] Furthermore, in the front pressing roller device 21 and the rear pressing roller device 22, the adjacent end surfaces of the two rollers 23 arranged alternately are flush.

[0042] Please refer to Figure 4 , wherein, for the two rollers 23 staggered in the front pressure roller device 21 and the rear pressure roller device 22, the adjacent end faces are kept in the same vertical plane. Therefore, when the strapping tape passes through two adjacent rollers 23 during the conveying process, the pressure acting on the surface of the strapping tape is continuous and uniform. The structure in which the end faces of the rollers 23 are flush can be achieved by precisely machining the size of the rollers 23, ensuring that the adjacent end faces of the rollers 23 are in the same plane after installation.

[0043] In some specific embodiments, the front roller device 21 includes two rollers 23, and the rear roller device 22 also includes two rollers 23. The two rollers 23 of the front roller device 21 are arranged in parallel along the width direction of the strapping tape, and the two rollers 23 of the rear roller device 22 are also arranged in parallel along the width direction of the strapping tape. The right side end face of the right roller 23 of the front roller device 21 and the left side end face of the right roller 23 of the rear roller device 22 are arranged alternately, the left side end face of the right side roller 23 of the front roller device 21 and the right side end face of the right side roller 23 of the rear roller device 22 are on the same vertical plane, and the end faces of the two rollers 23 are consistent in height, so that the end faces are flush. When multiple strapping tapes pass through the rollers 23 in parallel, at the intersection of the rollers 23, the pressure on the surface of the strapping tape is smoothly transitioned, and there will be no pressure change caused by the height difference of the rollers 23, so that the embossed pattern on the surface of the strapping tape is uniform.

[0044] Furthermore, it also includes a lifting device 3, which at least includes a first lifting device 31 and a second lifting device 32; The first lifting device 31 is connected to each roller 23 in the front pressure roller device 21, and is used to drive the front pressure roller device 21 to move up and down; The second lifting device 32 is connected to each roller 23 in the rear pressure roller device 22 and is used to drive the rear pressure roller device 22 to move up and down.

[0045] Please refer to Figure 1 , Figure 2 The first lifting device 31 is connected to the front pressure roller device 21, and the second lifting device 32 is connected to the rear pressure roller device 22, so that the front pressure roller device 21 and the rear pressure roller device 22 can move up and down respectively. Each lifting device 3 includes at least two driving parts 38, and each driving part 38 is connected to a roller 23, so that the position of each roller 23 can be adjusted. The gap between the roller 23 and the strapping tape is adjusted by the lifting device 3 to adapt to strapping tapes of different thicknesses, and the pressure of the roller 23 is adjusted according to the embossing requirements to improve the adaptability of the embossing unit.

[0046] Specifically, by setting the first lifting device 31 and the second lifting device 32, the front pressure roller device 21 and the rear pressure roller device 22 can be driven to move up and down respectively. In actual use, the first lifting device 31 and the second lifting device 32 can be operated according to the thickness of the strapping tape to adjust the height of the front pressure roller device 21 and the rear pressure roller device 22, and then adjust the gap between the roller 23 and the strapping tape. When a thicker strapping tape needs to be processed, the front pressure roller device 21 and the rear pressure roller device 22 can be moved upward to increase the gap between the roller 23 and the strapping tape; when a thinner strapping tape needs to be processed, the front pressure roller device 21 and the rear pressure roller device 22 can be moved downward to reduce the gap between the roller 23 and the strapping tape. By adjusting the gap between the roller 23 and the strapping tape, the embossing unit can adapt to strapping tapes of different thicknesses. In addition, the pressure of the roller 23 on the strapping tape can be adjusted according to the actual needs of embossing. For example, when a deeper pattern is required, the pressure can be increased, and vice versa.

[0047] Further, the first lifting device 31 at least includes a first mounting plate 33 arranged horizontally; One end of the first mounting plate 33 is fixed on the embossing machine frame 1, and the first mounting plate 33 and the embossing machine frame 1 are fixed in a right angle structure; The upper end surface of the first mounting plate 33 is used for mounting the first driving device 35 , and the lower end surface is used for mounting the front pressure roller device 21 . The first driving device 35 is connected to each roller wheel 23 in the front pressure roller device 21 .

[0048] Among them, the horizontally arranged first mounting plate 33 serves as a mounting platform. One end of the first mounting plate 33 is fixed on the embossing machine frame 1, so that the component is fixedly connected to the embossing machine frame 1. The first mounting plate 33 and the embossing machine frame 1 are fixed in a right-angle structure, so that the structure is stable. The upper end surface of the first mounting plate 33 is used to install the first driving device 35, and the lower end surface is used to install the front pressure roller device 21, so that the installation of the driving device and the pressure roller device is realized. The first driving device 35 is connected to each roller 23 in the front pressure roller device 21, so that the driving device can drive each roller 23. Therefore, the first mounting plate 33, as a horizontal and right-angle fixed mounting platform, can provide stable support for the first driving device 35 and the front pressure roller device 21. The connection between the first driving device 35 and each roller 23 realizes the individual drive of each roller 23.

[0049] Specifically, the technical solution of the above-mentioned first lifting device 31 is intended to solve the technical problem that the lifting device 3 is not designed rationally and cannot stably and reliably drive the front roller device 21 to move up and down. The first mounting plate 33 is horizontally arranged and fixed at right angles to the embossing machine frame 1, providing a stable mounting platform for the first drive device 35 and the front roller device 21, ensuring that the first drive device 35 can stably and reliably drive the front roller device 21 to move up and down. The upper end surface of the first mounting plate 33 is used to install the first drive device 35, and the lower end surface is used to install the front roller device 21, so that the layout structure of the first drive device 35 and the front roller device 21 is compact, saving space, and making the structure of the lifting device 3 more reasonable. The first drive device 35 is connected to each roller 23 in the front roller device 21, and each roller 23 can be driven separately, so that the lifting and lowering of each roller 23 is more precise and the embossing effect is better.

[0050] In some specific embodiments, the first mounting plate 33 can be made of steel plate material, and one end of the first mounting plate 33 is fixedly connected to the embossing machine frame 1 by bolts or welding, and the first mounting plate 33 is ensured to be perpendicular to the embossing machine frame 1 at 90 degrees. The first driving device 35 can be an electric push rod, the fixed end of the electric push rod is installed on the upper end surface of the first mounting plate 33, and the output end of the electric push rod is connected to the bearing seats at both ends of the rotating shaft of the roller 23 of the front roller device 21. By controlling the extension and contraction of the electric push rod, the lifting and lowering adjustment of the roller 23 is achieved. The first mounting plate 33 made of steel plate has sufficient strength and rigidity, and can provide stable support for the components installed thereon. The electric push rod has high driving accuracy, and can achieve precise lifting and lowering control of the roller 23.

[0051] Further, the second lifting device 32 at least includes a second mounting plate 34 disposed horizontally; One end of the second mounting plate 34 is fixed on the embossing machine frame 1, and the second mounting plate 34 and the embossing machine frame 1 are fixed in a right angle structure; The upper end surface of the second mounting plate 34 is used for mounting the second driving device 36 , and the lower end surface is used for mounting the rear pressure roller device 22 . The second driving device 36 is connected to each roller wheel 23 in the rear pressure roller device 22 .

[0052] Among them, the second mounting plate 34 is arranged horizontally to provide a mounting plane for the second driving device 36 and the rear pressure roller device 22. One end of the second mounting plate 34 is fixed on the embossing machine frame 1 at a vertical angle to form a stable support structure. The second driving device 36 is installed on the upper end surface of the second mounting plate 34, and the rear pressure roller device 22 is installed on the lower end surface of the second mounting plate 34. The second driving device 36 is connected to each roller 23 of the rear pressure roller device 22 to drive each roller 23. As a possible implementation, the second mounting plate 34 can be made of steel plate material and fixedly connected to the embossing machine frame 1 by bolt fastening to ensure installation strength and stability. The second driving device 36 can use a screw lifting mechanism, the output end of the screw lifting mechanism is connected to the bearing seat of the roller 23, and the upper and lower positions of the roller 23 are adjusted by rotating the screw.

[0053] Specifically, when the embossing unit is working, the rear roller device 22 needs to be raised and lowered to adapt to different thicknesses of strapping tape or embossing requirements. The lifting and lowering of the rear roller device 22 can be independently controlled by the second lifting device 32. The horizontally arranged second mounting plate 34 provides a stable installation base for the second drive device 36 and the rear roller device 22 to ensure stability during the lifting process. The second mounting plate 34 is fixed to the embossing machine frame 1 with a right-angle structure, which enhances the structural strength and stability of the entire device and resists vibrations and impacts generated during operation. The second drive device 36 is connected to each roller 23 of the rear roller device 22, so that the height of each roller 23 can be adjusted separately, so as to achieve precise lifting and lowering control of the rear roller device 22, thereby ensuring the consistency of the embossing effects of multiple strapping tapes.

[0054] Furthermore, mounting side plates 37 are fixed on both sides of the first mounting plate 33 and the second mounting plate 34, and the mounting side plates 37 are fixed to the embossing machine frame 1, and form a supporting frame structure with the first mounting plate 33 and the second mounting plate 34 respectively to support the components installed on the first mounting plate 33 and the second mounting plate 34 respectively.

[0055] The mounting side plate 37 is configured to be fixed on two sides of the first mounting plate 33 and the second mounting plate 34. The mounting side plate 37 is further fixedly connected to the embossing machine frame 1, whereby the mounting side plate 37, the first mounting plate 33 and the embossing machine frame 1 together form a frame structure, and similarly, the mounting side plate 37, the second mounting plate 34 and the embossing machine frame 1 also form a frame structure. This frame structure has higher strength and stability than a single flat plate structure. By combining the mounting side plate 37 with the mounting plate and the embossing machine frame 1, the rigidity of the overall structure can be effectively enhanced, thereby providing a more stable support for the components mounted on the first mounting plate 33 and the second mounting plate 34.

[0056] Specifically, when the embossing unit is working, the roller 2 of the embossing machine generates embossing pressure on the strapping tape, and this pressure will be transmitted to the components supporting the roller 2 of the embossing machine. If it only relies on the flat plate structure of the first mounting plate 33 and the second mounting plate 34, it may bend or deform under long-term pressure, causing the position of the driving device and the roller device installed thereon to shift, thereby affecting the precision and effect of the embossing. By adding the mounting side plate 37 and fixing it to the embossing machine frame 1 to form a frame structure, the bending and deformation resistance of the first mounting plate 33 and the second mounting plate 34 can be significantly improved. The mounting side plate 37 is like the side beam of the frame, and works together with the first mounting plate 33 and the second mounting plate 34 as the top beam and the bottom beam to disperse and bear the pressure, thereby ensuring the stability of the entire structure and the accuracy of the component installation position. In this way, it can be ensured that the embossing unit can still maintain a stable embossing effect and product quality during long-term operation.

[0057] In some specific embodiments, the mounting side plate 37 can be designed as a vertical steel plate, and its shape can be a right-angled trapezoid that is approximately triangular to adapt to different installation requirements and structural layouts. The mounting side plate 37 is fixed to the sides of the first mounting plate 33 and the second mounting plate 34 by bolts, welding or other fastening methods, and is further fixed to the embossing machine frame 1 using bolts or other fasteners. As a preferred embodiment, the mounting side plate 37 is bolted to the first mounting plate 33, the second mounting plate 34 and the embossing machine frame 1 for easy assembly and maintenance. The thickness and height of the mounting side plate 37 can be adjusted according to the size of the embossing unit, the weight of the components and the expected embossing pressure to meet different strength and stability requirements. In this way, effective support and reinforcement of the first mounting plate 33 and the second mounting plate 34 can be achieved, thereby improving the overall structural strength of the embossing unit.

[0058] Furthermore, the first driving device 35 and the second driving device 36 each include at least two driving parts 38 , and each driving part 38 is correspondingly connected to a roller 23 to drive the roller 23 to move up and down.

[0059] The first driving device 35 and the second driving device 36 are both configured to include at least two driving parts 38, so as to realize independent driving and control of each roller 23. Each driving part 38 is connected to a roller 23, and this structure allows the up and down movement of each roller 23 to be adjusted individually. Specifically, each driving part 38 can be an independent driving element, which controls the corresponding roller 23 respectively. Through this independent control, the pressure applied by each roller 23 can be accurately adjusted to adapt to strapping tapes of different thicknesses or materials, and ensure the uniformity of the embossing effect.

[0060] Specifically, when the embossing unit is working, the operator can set each drive unit 38 individually according to actual production needs, such as the material, thickness and desired embossing depth of the strapping tape. If it is found that the embossing effect of a certain strapping tape is not ideal, the drive unit 38 of the corresponding roller 23 can be adjusted individually to increase or decrease the pressure of the roller 23 without affecting the working state of other rollers 23. This refined pressure control enables the embossing unit to adapt to more types of strapping tape embossing needs, improves production flexibility and product quality stability. In addition, the use of multiple drive units 38 to independently control the rollers 23 also facilitates the maintenance and repair of the equipment. If a drive unit 38 fails, it can be replaced or repaired individually without affecting the operation of the entire embossing unit.

[0061] Further, the driving part 38 at least includes a hand grip 381, a first screw rod 382 connected to the hand grip 381, a steering gear 383 connected to the first screw rod 382, ​​and a second screw rod 384 connected to the steering gear 383 and the roller 23 respectively; The first screw rod 382 is meshed with the steering gear 383, one end of the second screw rod 384 is inserted into the center of the gear shaft of the steering gear 383, and the other end is connected to the roller 23; the second screw rod 384 rotates coaxially with the steering gear 383; The first screw rod 382 cooperates with the steering gear 383 to convert the axial rotation force of the hand grip 381 around the first screw rod 382 into the axial rotation force around the steering gear 383, and the second screw rod 384 transmits the axial rotation force around the steering gear 383 to the roller 23, so that the roller 23 rises or falls along the rack spiral on the second screw rod 384.

[0062] Please refer to Figure 2 , Figure 3 , the hand grip 381 serves as the starting end of the operation, and the operator applies a rotational force through the hand grip 381. The first screw rod 382 is connected to the hand grip 381, and the rotational motion of the hand grip 381 is directly transmitted to the first screw rod 382. The first screw rod 382 is meshed with the steering gear 383. The steering gear 383 is a gear that can change the transmission direction, and the linear motion of the first screw rod 382 is converted into the rotational motion of the steering gear 383. The second screw rod 384 is coaxially fixed with the steering gear 383, which means that the second screw rod 384 will rotate synchronously with the steering gear 383. The second screw rod 384 is connected to the roller 23. When the steering gear 383 drives the second screw rod 384 to rotate, the cooperation between the second screw rod 384 and the roller 23 converts the rotational motion into the linear motion of the roller 23 again, specifically the up and down movement of the roller 23. By adjusting the rotation angle of the grip portion 381, the lifting height of the roller 23 can be accurately controlled, thereby achieving fine adjustment of the position of the roller 23 of the roller press.

[0063] Furthermore, a second screw rod 384 is respectively disposed at both ends of each roller 23 , and each second screw rod 384 corresponds to a steering gear 383 .

[0064] Each roller 23 is provided with an independent steering gear 383, a first screw rod 382 and a hand grip 381. The hand grip 381 is connected to the first screw rod 382. The operator can directly drive the first screw rod 382 to rotate by operating the hand grip 381, so that the rotation of the first screw rod 382 can drive the steering gear 383 to rotate. The steering gear 383 is then connected to the roller 23 through the second screw rod 384, so that the hand grip 381 drives the first screw rod 382, ​​and the second screw rod 384 drives the roller 23 to move up and down through the transmission of the first screw rod 382 and the steering gear 383. Each roller 23 adopts the above-mentioned independent driving structure, so that the lifting and lowering adjustment structure of each roller 23 is relatively independent.

[0065] Furthermore, the steering gear 383 corresponding to each roller 23 is driven by a first screw rod 382 and a grip portion 381 .

[0066] Among them, two second screw rods 384 are connected to each roller 23, but only one steering gear 383, one first screw rod 382 and a hand grip 381 are configured. The rotation of the hand grip 381 drives the first screw rod 382 to rotate, and the first screw rod 382 is engaged with the steering gear 383, thereby driving the steering gear 383 to rotate. The rotation of the steering gear 383 simultaneously controls the two second screw rods 384 to transmit force to the roller 23, so as to achieve the up and down movement adjustment of the roller 23. This structure simplifies the lifting mechanism, reduces the number of parts, and reduces the manufacturing cost and assembly complexity.
