Description

Technical Field

[0001] This utility model relates to the technical field of filter cloth embossing equipment, and in particular to a filter cloth embossing equipment that can quickly change molds. Background Technology

[0002] In filter cloth production, the embossing process is crucial for improving the structural stability and appearance diversity of the filter cloth. It requires frequent changes to the embossing molds (such as patterns and pore sizes) to meet different customer needs. Currently, mold changes in mainstream filter cloth embossing equipment are still primarily manual, which has certain drawbacks. Firstly, the disassembly and assembly process is cumbersome, time-consuming, and labor-intensive. Existing molds are mostly fixed to the equipment mold base by multiple sets of bolts. When replacing them, it is necessary to manually remove each bolt and then move the heavy mold (a single set often weighs 20-50kg) for alignment and installation. The whole process requires 1-2 people to work together and generally takes more than 30 minutes, which greatly extends the equipment downtime and seriously restricts the continuous operation efficiency of the production line. Secondly, the positioning accuracy depends on manual operation, which can easily lead to quality problems. During manual installation, the relative position of the mold and the mold base needs to be repeatedly calibrated. If deviations occur (such as horizontal offset or verticality error), it can easily lead to misalignment of the embossed pattern and damage to the filter cloth, increasing the defect rate. Moreover, long-term manual operation can easily lead to poor installation consistency due to personnel fatigue, further affecting the stability of product quality. Third, there is a lack of auxiliary cleaning and guiding structures. During mold replacement, filter cloth fibers, dust and other impurities easily accumulate in the mold base slide groove. Incomplete manual cleaning can lead to subsequent mold sliding jamming. At the same time, without a dedicated guiding and load-bearing mechanism, the mold is prone to bumping into the equipment during handling, which shortens the service life of the mold and the equipment. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a filter cloth embossing device that can quickly change molds. It solves the technical problems of cumbersome mold disassembly and assembly processes, time-consuming and labor-intensive processes, and the accuracy issues that affect the quality of filter cloth embossing due to manual disassembly and assembly. This achieves the goal of improving disassembly and assembly efficiency and installation accuracy.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a filter cloth embossing device that can quickly change molds, including an embossing machine support platform, an embossing roller assembly for embossing the filter cloth is installed on the embossing machine support platform, a T-shaped groove is opened on the embossing machine support platform, a T-shaped slider is fixedly connected to the bottom of the embossing roller assembly and slides in the T-shaped groove, a lead screw is rotatably connected to one side of the top of the embossing machine support platform through a bearing seat, a threaded slider is threadedly connected to the lead screw, a push-pull assembly is fixedly connected to the side of the threaded slider and slides on the embossing machine support platform, and the push-pull assembly is connected to the embossing roller assembly, and a drive motor for driving the lead screw to rotate is installed on the embossing machine support platform.

[0005] A further improvement is that a lifting groove connected to a T-shaped slide is provided on one side of the top of the embossing machine support platform, and strip grooves are provided on both sides of the top of the embossing machine support platform.

[0006] A further improvement is that multiple electric push rods are arrayed and installed in the strip groove, and the free end of the electric push rod is fixedly connected to a support plate that slides in the strip groove. Rollers that support the embossing roller assembly and the push-pull assembly are rotatably connected in an array inside the support plate.

[0007] A further improvement is that a guide rod is fixedly connected to the other side of the top of the embossing machine's support platform via a mounting seat, and a guide slider is slidably mounted on the guide rod and fixedly connected to the other side of the push-pull assembly.

[0008] A further improvement is that the push-pull assembly includes a push-pull seat installed between the threaded slider and the guide slider. An electric lifting rod is installed on the side of the push-pull seat. An installation plate is fixed to the free end of the electric lifting rod. Insertion rods are fixed to both sides of the bottom of the installation plate. Positioning sleeves adapted to the insertion rods are fixed to both sides of the embossing roller assembly.

[0009] A further improvement is that the area of ​​the T-shaped slide groove is larger than the area of ​​the T-shaped slider, rubber airbags are installed on the inner walls of both sides of the T-shaped slide groove, and air jet holes for blowing away debris inside the T-shaped slide groove are arrayed on the rubber airbags. A chip removal groove is formed through the bottom of the T-shaped slide groove. A further improvement is that the rubber airbag is made of nitrile rubber, and the air jet hole is a downward-sloping conical hole structure.

[0010] By employing the above technical solution, this utility model provides a filter cloth embossing device that can quickly change molds, which has at least the following beneficial effects: 1. This utility model uses a drive motor to rotate a lead screw, which in turn drives a threaded slider to pull the push-pull assembly and the embossing roller assembly outward. This causes the T-shaped slider to slide outward along the T-shaped groove into the lifting slot. Then, a new embossing roller assembly is hoisted and replaced. The drive motor is reversed to push the T-shaped slider at the bottom of the new embossing roller assembly against the other end of the T-shaped groove, thus completing the positioning of the new embossing roller assembly. No manual operation is required, making disassembly and assembly faster and more convenient. It also avoids the problem of insufficient positioning accuracy during manual installation, which affects the printing quality.

[0011] 2. This utility model uses an electric push rod to push the support plate upward until the rollers inside the support plate slightly lift the push-pull assembly and the embossing roller assembly, thereby changing the original sliding friction into rolling friction, reducing the coefficient of friction, preventing the lead screw from being deformed due to excessive force, and slightly disengaging the embossing roller assembly and T-shaped slider from the embossing machine support table and T-shaped groove, thus avoiding contact with impurities in the table and groove that could cause scratches.

[0012] 3. This utility model uses a T-shaped slider that slides at the bottom of the new embossing roller assembly to squeeze the rubber airbags on both sides of the T-shaped groove, and squeezes the air inside them out through the air jet hole. Since the air jet hole is a downward-sloping conical hole structure, it blows the impurities and debris at the bottom of the T-shaped groove into the chip discharge groove for discharge, thereby avoiding the accumulation of impurities and debris in the T-shaped groove, which could scratch the T-shaped slider and cause the embossing roller assembly to jam.

[0016] 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.

[0017] Example 1 Addressing the issues of cumbersome, time-consuming, and labor-intensive mold assembly and disassembly processes, as well as the accuracy problems associated with manual assembly and disassembly affecting the quality of filter cloth embossing, this embodiment provides a filter cloth embossing device that allows for rapid mold replacement, thereby improving assembly and disassembly efficiency and installation accuracy. Please refer to... Figures 1-6 The filter cloth embossing equipment, which can quickly change molds, includes an embossing machine support platform 1, an embossing roller assembly 2 for embossing the filter cloth installed on the embossing machine support platform 1, a T-shaped groove 3 opened on the embossing machine support platform 1, a T-shaped slider 4 fixedly connected to the bottom of the embossing roller assembly 2 and slidably disposed in the T-shaped groove 3, a lead screw 5 rotatably connected to one side of the top of the embossing machine support platform 1 through a bearing seat, a threaded slider 6 threadedly connected to the lead screw 5, a push-pull assembly 7 fixedly connected to the side of the threaded slider 6 and slidably disposed on the embossing machine support platform 1, and the push-pull assembly 7 connected to the embossing roller assembly 2, and a drive motor 8 for driving the lead screw 5 to rotate is installed on the embossing machine support platform 1.

[0018] The top of the embossing machine's support platform 1 has a lifting groove connected to the T-shaped slide 3 on one side, and strip grooves are provided on both sides of the top of the support platform 1. When it is necessary to replace the embossing roller assembly 2, the push-pull assembly 7 is connected to the embossing roller assembly 2. Then, the drive motor 8 is started to drive the lead screw 5 to rotate, which in turn drives the threaded slider 6 to pull the push-pull assembly 7 to move outward. This causes the T-shaped slider 4 at the bottom of the embossing roller assembly 2 to slide outward along the T-shaped slide 3 into the lifting groove. Then, the embossing roller assembly 2 is lifted by the lifting ring at its top. After replacing it with a new embossing roller assembly 2, the process is reversed. The drive motor 8 pushes the new embossing roller assembly 2 into the embossing machine until the T-shaped slider 4 at the bottom of the new embossing roller assembly 2 abuts against the other end of the T-shaped groove 3, thus completing the positioning of the new embossing roller assembly 2. No manual operation is required, making disassembly and assembly faster and more convenient. It also avoids the problem of insufficient positioning accuracy during manual installation, which affects the printing quality. In addition, the T-shaped structure can effectively limit the vertical sway of the embossing roller assembly 2. Together with the bottom embossing machine support platform 1, it can form a stable support system, which can better withstand radial force and avoid the problem of tilting and jamming of the embossing roller assembly 2.

[0019] Because the embossing roller assembly 2 and its bottom T-shaped slider 4 slide directly within the embossing machine's support platform 1 and T-shaped groove 3, impurities may cause scratches on the contact surface, and the sliding friction resistance is relatively large, which may lead to deformation or even breakage of the lead screw 5. Therefore, multiple electric push rods 91 are arrayed and installed in the strip groove. The free end of the electric push rod 91 is fixedly connected to a support plate 92 that slides in the strip groove. Rollers 93 that support the embossing roller assembly 2 and the push-pull assembly 7 are rotatably connected in an array within the support plate 92. When the embossing roller assembly 2 is removed for disassembly... Since the area of ​​the T-shaped groove 3 is slightly larger than that of the T-shaped slider 4, the T-shaped slider 4 has a slight upward sliding space. The electric push rod 91 is activated to push the support plate 92 upward until the roller 93 in the support plate 92 slightly lifts the push-pull assembly 7 and the embossing roller assembly 2, thereby changing the original sliding friction into rolling friction, reducing the coefficient of friction, and preventing the lead screw 5 from being deformed due to excessive force. In addition, the embossing roller assembly 2 and the T-shaped slider 4 are slightly separated from the embossing machine support table 1 and the T-shaped groove 3, thereby avoiding contact with impurities in the table and groove that could cause scratches.

[0020] Since the lead screw 5 drives the threaded slider 6 to pull the push-pull assembly 7 from one side, it may cause the center of gravity to shift, affecting its sliding stability. Therefore, a guide rod 61 is fixedly connected to the other side of the top of the embossing machine platform 1 through a mounting seat. A guide slider 62, which is fixedly connected to the other side of the push-pull assembly 7, slides on the guide rod 61. When the lead screw 5 rotates and drives the threaded slider 6 to pull the push-pull assembly 7 to slide outward, the guide slider 62 on the other side of the push-pull assembly 7 slides on the guide rod 61 at the same time, thereby improving the sliding stability of the push-pull assembly 7 and avoiding the center of gravity shift.

[0021] Specifically, the push-pull assembly 7 includes a push-pull seat 71 installed between the threaded slider 6 and the guide slider 62. An electric lifting rod 72 is installed on the side of the push-pull seat 71. An installation plate 73 is fixedly connected to the free end of the electric lifting rod 72. Insertion rods 74 are fixedly connected to both sides of the bottom of the installation plate 73. Positioning sleeves 75 that are adapted to the insertion rods 74 are fixedly connected to both sides of the embossing roller assembly 2. When it is necessary to disassemble the embossing roller assembly 2, the positioning rod on the embossing machine is pulled out from the positioning sleeve 75 to release the lock. Then, the electric lifting rod 72 is started to drive the insertion rod 74 on the installation plate 73 to move down and insert into the positioning sleeve 75 on one side of the embossing roller assembly 2, thus completing the locking of the push-pull seat 71 and the embossing roller assembly 2. Then, it is pulled out to replace the mold of different specifications.

[0022] Example 2 Since debris and impurities inevitably accumulate inside the T-shaped groove 3 during the embossing process, to prevent the accumulation of debris and impurities from scratching the T-shaped slider 4 and causing the embossing roller assembly 2 to jam during transfer, therefore, based on Embodiment 1, as follows... Figures 1-6As shown, the area of ​​the T-shaped slide 3 is larger than the area of ​​the T-shaped slider 4. Rubber airbags 41 are installed on the inner walls of both sides of the T-shaped slide 3. Air jet holes 42 are arrayed on the rubber airbags 41 to blow away debris inside the T-shaped slide 3. A chip discharge groove 43 is formed through the bottom of the T-shaped slide 3. The rubber airbag 41 is made of nitrile rubber, and the air jet 42 is a downward-sloping conical hole structure. When the new embossing roller assembly 2 is ready to be pushed and installed, the sliding T-shaped slider 4 squeezes the rubber airbag 41 on both sides of the inner wall of the T-shaped groove 3, and squeezes the air inside it out through the air jet 42. Since the air jet 42 is a downward-sloping conical hole structure, it blows the impurities and debris at the bottom of the T-shaped groove 3 into the chip discharge groove 43 for discharge, thereby avoiding the accumulation of impurities and debris in the T-shaped groove 3, scratching the T-shaped slider 4, and causing the embossing roller assembly 2 to jam during transfer.
