Description
Technical Field
[0001] This utility model relates to the technical field of microfiber suede production, and more specifically, to a differential speed roller kneading type microfiber suede finishing machine. Background Technology
[0002] Differential roller rubbing microfiber suede finishing technology uses differential rubbing to make the pile smoother, more uniform and natural, eliminating problems such as indentations or uneven pile flattening caused during the production process. Differential roller rubbing microfiber suede finishing technology can improve the hand feel of microfiber suede and achieve a high-end antique effect. However, existing differential roller kneading microfiber suede finishing machines, when kneading and finishing microfiber suede with multiple sets of differential rollers, will cause damage or even tearing during the kneading and finishing process due to excessive tension of the microfiber suede. At the same time, if the tension of the microfiber suede is too low, the microfiber suede cannot be well supported and unfolded, and some parts of the microfiber suede cannot be kneaded and finished properly, thus affecting the production quality of microfiber suede.
[0003] Therefore, a differential speed double roller kneading type microfiber suede finishing machine is proposed to address the above problems. Utility Model Content
[0004] In order to overcome the above-mentioned defects of the prior art, this utility model provides a differential speed double roller kneading type microfiber suede finishing machine to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a differential-speed roller kneading type microfiber suede finishing machine, comprising a worktable, a mounting frame fixedly mounted on the worktable, a set of electric push rods symmetrically fixedly mounted on the upper surface of the worktable and the top of the mounting frame, a connecting frame fixedly connected to the output end of each set of electric push rods, a connecting bracket slidably connected to each of the two connecting frames, multiple damping springs connected between the connecting frames and the connecting brackets, an elastic extrusion column fixedly mounted on the connecting frame, a pressure sensor fixedly mounted on the connecting bracket to detect the kneading pressure in real time, a mounting base fixedly connected to the side of the connecting bracket away from the damping springs, a limiting roller with a surface covered with a soft wear-resistant silicone layer and used for guiding and assisting in tensioning the microfiber suede fabric rotatably connected to the mounting base, a signal controller electrically connected to the electric push rods fixedly mounted on the upper surface of the worktable, and a signal controller connected to the signal controller fixedly mounted on the upper surface of the worktable and on the side of the signal controller. The buzzer, electrically connected to the controller, activates when the microfiber suede tension is too low. The damping spring pulls the connecting frame, mounting base, limit rollers, and pressure sensor away from the elastic extrusion column. At this point, the pressure sensor disengages from the elastic extrusion column, reducing the pressure detected by the sensor. The signal controller then controls four electric push rods to move the two limit rollers away from each other, thus supporting and unfolding the microfiber suede with low tension. When the microfiber suede tension is too high, it squeezes and pulls the two limit rollers, causing the two pressure sensors to move towards the elastic extrusion column. The pressure sensors then sense an increase in pressure from the elastic extrusion column. The signal controller then controls the four electric push rods to move the two limit rollers closer together, reducing the tension of the microfiber suede and preventing damage or tearing during the rubbing and finishing process by the two sets of rubbing rollers, which would affect the production quality of the microfiber suede.
[0006] Preferably, the pressure sensor on the mounting bracket is located above the elastic extrusion column, and the pressure sensor on the worktable is located below the elastic extrusion column, with the sensing surface of the pressure sensor in close contact with the end of the elastic extrusion column, for detecting the tension pressure of the upper and lower sets of limiting rollers on the microfiber suede respectively.
[0007] Preferably, two fixed seats are symmetrically fixedly connected to the upper surface of the worktable and on both sides of the two limiting rollers. A lower rotating shaft is rotatably connected between the two fixed seats. An upper rotating shaft is rotatably connected to each of the two fixed seats and above the two lower rotating shafts. The upper rotating shaft and the lower rotating shaft are distributed in a pair of rollers for clamping microfiber suede for kneading and finishing.
[0008] Preferably, a kneading roller is fixedly sleeved and connected to the outer side of each of the two lower rotating shafts and the two upper rotating shafts. Multiple soft rubber arc-shaped kneading protrusions are fixedly arranged at equal intervals on the outer side of each of the four kneading rollers. In use, the microfiber suede is passed between the two kneading rollers and kneaded by the kneading rollers and kneading protrusions arranged on the outer side of the lower rotating shafts and the upper rotating shafts.
[0009] Preferably, a small gear is fixedly connected to the outer side of one end of each of the two lower rotating shafts, and a large gear that meshes with the small gear is fixedly connected to the outer side of one end of each of the two upper rotating shafts. A drive motor for driving the upper rotating shaft is fixedly connected to the other end of each of the two upper rotating shafts. The transmission ratio between the small gear and the large gear is 1:1.5-1:2.5, achieving differential rotation between the upper and lower rotating shafts through gear meshing. The drive motor is a speed-regulating servo motor. In use, the drive motor drives the upper rotating shaft to rotate, which in turn drives the large gear to rotate. The large gear, through meshing with the small gear, drives the lower rotating shaft and the rubbing rollers located on the outer side of the lower rotating shaft to rotate rapidly. At this time, a differential speed occurs between the rubbing rollers on the outer side of the upper and lower rotating shafts. This differential speed between the two rubbing rollers allows for better rubbing of the microfiber suede.
[0010] Preferably, a connecting column is fixedly connected to each of the four corners of the bottom wall of the workbench, and the bottom ends of the four connecting columns are connected to a base. When the device is in use, the four connecting columns and the base work together to provide stable support for the entire device.
[0011] Preferably, a collection trough is slidably connected to the upper surface of the base, and a handle for pulling the collection trough is fixedly connected to the surface of the collection trough by bolts. An inclined guide frame is fixedly installed on the upper surface of the workbench and directly above the collection trough. The guide frame guides the fur and dust debris that fall from the upper surface of the workbench to the collection trough for unified collection. Finally, the collection trough is removed from the upper surface of the base by pulling the handle, and the fur and dust debris collected in the collection trough are cleaned.
[0012] The technical effects and advantages of this utility model are as follows: Compared with existing technologies, this differential-speed roller kneading type microfiber suede finishing machine supports the tension of microfiber suede through two limiting rollers. When the tension of the microfiber suede is too low, the pressure detected by the pressure sensor decreases, and then the signal controller controls four electric push rods to move the two limiting rollers away from each other, thereby supporting and unfolding the microfiber suede with low tension. When the tension of the microfiber suede is too high, the signal controller controls four electric push rods to drive the two limiting rollers closer to each other, thereby reducing the tension of the microfiber suede. This prevents the microfiber suede from being damaged or even torn during the kneading and finishing process due to excessive tension when the two sets of kneading rollers are kneading and finishing, which would affect the production quality of the microfiber suede. This structure can detect the tension of the microfiber suede in real time and adjust the tension of the microfiber suede according to the detection results. Attached Figure Description

[0018] 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.
[0019] Example 1 As attached Figures 1 to 4The differential-speed roller kneading type microfiber suede finishing machine shown includes a worktable 1, on which a mounting frame 2 is fixedly mounted. A set of electric push rods 3 are symmetrically fixedly mounted on the upper surface of the worktable 1 and the top of the mounting frame 2. Each set of electric push rods 3 has a connecting frame 4 fixedly connected to its output end. A connecting frame 5 is slidably connected to each of the two connecting frames 4. Multiple damping springs 6 connect the connecting frames 4 and the connecting frame 5. Elastic extrusion columns 9 are fixedly mounted on the connecting frames 4. A pressure sensor 10 is located above the elastic extrusion columns 9 on the mounting frame 2. The worktable 1... The pressure sensor 10 is located below the elastic extrusion column 9. The pressure sensor 10 is fixedly installed on the connecting frame 5 to detect the kneading pressure in real time. The mounting base 7 is fixedly connected to the side of the connecting frame 5 away from the damping spring 6. The mounting base 7 is rotatably connected to the limiting roller 8, which is covered with a soft wear-resistant silicone layer and is used to guide and assist in tensioning the microfiber suede fabric. The upper surface of the worktable 1 is fixedly installed with a signal controller 11 that is electrically connected to the electric push rod 3. The upper surface of the worktable 1 and the side of the signal controller 11 is fixedly installed with a buzzer 12 that is electrically connected to the signal controller 11.
[0020] In operation, the device uses two limiting rollers 8 to support the tension of the microfiber suede. When the tension is too low, the damping spring 6 pulls the connecting frame 5, mounting base 7, limiting rollers 8, and pressure sensor 10 away from the elastic extrusion column 9. At this time, the pressure sensor 10 disengages from the elastic extrusion column 9, and the pressure detected by the pressure sensor 10 decreases. Subsequently, the signal controller 11 controls the four electric push rods 3 to control the two limiting rollers 8 to move away from each other, thereby supporting and unfolding the microfiber suede with low tension. When the tension is too high, the microfiber suede will squeeze and pull the two limiting rollers 8. At this time, the limiting rollers 8 on the mounting frame 2 will drive the pressure sensor 10 to move downwards, while the pressure sensor 10 on the worktable 1 will move downwards. The limiting roller 8 will drive the pressure sensor 10 to move upward, which will cause the two pressure sensors 10 to move towards the elastic extrusion column 9 respectively. At this time, the pressure sensor 10 senses the increase in pressure from the elastic extrusion column 9. When the pressure value is higher than the preset value range, the signal controller 11 will control the four electric push rods 3 to drive the two limiting rollers 8 to move closer to each other, thereby reducing the tension of the microfiber suede. This prevents the microfiber suede from being damaged or even torn during the rubbing and finishing process due to excessive tension when the two sets of rubbing rollers 16 are rubbing and finishing the microfiber suede, which would affect the production quality of the microfiber suede. This structure can detect the tension of the microfiber suede in real time and improve and adjust the tension of the microfiber suede based on the detection results.
[0021] Example 2 Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 4 As shown below, see details: In a preferred embodiment, two fixed seats 13 are symmetrically fixedly connected to the upper surface of the worktable 1 on both sides of the two limiting rollers 8. A lower rotating shaft 14 is rotatably connected between the two fixed seats 13. An upper rotating shaft 15 is rotatably connected to each of the two fixed seats 13 above the two lower rotating shafts 14. A kneading roller 16 is fixedly sleeved on the outer side of each of the two lower rotating shafts 14 and the two upper rotating shafts 15. Multiple soft rubber arc-shaped kneading protrusions 17 are fixedly fixed at equal intervals on the outer side of the four kneading rollers 16. A small gear 18 is fixedly connected to the outer side of one end of each of the two lower rotating shafts 14. A large gear 19 that meshes with the small gear 18 is fixedly connected to the outer side of one end of each of the two upper rotating shafts 15. A drive motor 20 that drives the upper rotating shaft 15 is fixedly connected to the other end of each of the two upper rotating shafts 15. The transmission ratio of the small gear 18 to the large gear 19 is 1:1.5-1: 2.5 Differential rotation between the upper rotating shaft 15 and the lower rotating shaft 14 is achieved through gear meshing; the drive motor 20 is a speed-regulating servo motor. In use, the drive motor 20 drives the upper rotating shaft 15 to rotate, and then the rotating upper rotating shaft 15 drives the large gear 19 to rotate. Then, the rotating large gear 19 is connected to the small gear 18 through meshing, which drives the lower rotating shaft 14 and the rubbing roller 16 set on the outside of the lower rotating shaft 14 to rotate rapidly. At this time, the rubbing roller 16 on the outside of the upper rotating shaft 15 and the rubbing roller 16 on the outside of the lower rotating shaft 14 have a differential speed. Through the two rubbing rollers 16 with differential speed, the microfiber suede is better rubbed. When rubbing the microfiber suede, the microfiber suede can pass between the two rubbing rollers 16 and be rubbed by the rubbing roller 16 and the rubbing protrusion 17 set on the outside of the lower rotating shaft 14 and the upper rotating shaft 15.
[0022] In a preferred embodiment, a connecting column 21 is fixedly connected to each of the four corners of the bottom wall of the workbench 1, and the bottom ends of the four connecting columns 21 are connected to a base 22. When the device is in use, the four connecting columns 21 and the base 22 cooperate to provide stable support for the entire device.
[0023] In a preferred embodiment, a collection trough 24 is slidably connected to the upper surface of the base 22. A handle 25 for pulling the collection trough 24 is fixedly connected to the surface of the collection trough 24 by bolts. An inclined guide frame 23 is fixedly installed on the upper surface of the workbench 1 and directly above the collection trough 24. The guide frame 23 guides the fur and dust debris falling from the upper surface of the workbench 1 to fall into the collection trough 24 for unified collection. Finally, the collection trough 24 is moved out of the upper surface of the base 22 by pulling the handle 25, thereby cleaning the fur and dust debris collected in the collection trough 24 and keeping the surface of the workbench 1 clean.
[0024] In this embodiment, the electric push rod 3, pressure sensor 10, signal controller 11, buzzer 12 and drive motor 20 are all commercially available devices known to those skilled in the art. They can be customized or selected according to actual needs. Here we are only using them without making any structural or functional improvements, and we will not go into detail here.
[0025] The working process of this utility model is as follows: First, the microfiber suede is passed between the two kneading rollers 16 in the first group. Then, the microfiber suede is passed under the limiting roller 8 on the worktable 1. Next, the microfiber suede is passed over the limiting roller 8 on the mounting frame 2. Finally, the microfiber suede is passed between the two kneading rollers 16 in the second group. The tension of the microfiber suede is supported by the two limiting rollers 8. When the tension of the microfiber suede is too low, the damping spring 6 pulls the connecting frame 5, mounting base 7, limiting roller 8, and pressure sensor 10 to move away from the elastic extrusion column 9. At this time, the pressure sensor 10 disengages from the elastic extrusion column 9, and the pressure detected by the pressure sensor 10 decreases. Subsequently, the signal controller 11 controls the four electric push rods 3 to control the two limiting rollers 8 to move away from each other, thereby supporting and unfolding the microfiber suede with low tension. This avoids the microfiber suede being too low in tension, which would prevent it from being properly supported and unfolded, and thus prevent some parts of the microfiber suede from being properly kneaded and shaped, thereby affecting the production quality of the microfiber suede. When the tension of the microfiber suede is too high, it will squeeze and pull the two limiting rollers 8. At this time, the limiting rollers 8 on the mounting frame 2 will drive the pressure sensor 10 to move downward, while the limiting rollers 8 on the worktable 1 will drive the pressure sensor 10 to move upward. This will cause the two pressure sensors 10 to move towards the elastic extrusion column 9 respectively. At this time, the pressure sensor 10 senses the increase in pressure from the elastic extrusion column 9. When the pressure value is higher than the preset value range, the signal controller 11 will control the four electric push rods 3 to drive the two limiting rollers 8 to move closer to each other, thereby reducing the tension of the microfiber suede. This prevents the microfiber suede from being damaged or even torn during the rubbing and finishing process due to excessive tension when the two sets of rubbing rollers 16 are rubbing and finishing the microfiber suede, which would affect the production quality of the microfiber suede. This structure can detect the tension of the microfiber suede in real time and improve and adjust the tension of the microfiber suede based on the detection results. Furthermore, when the tension of the microfiber suede is too high or too low, and it is impossible to adjust it by pushing the two limit rollers 8 through the electric push rod 3, the signal controller 11 will control the buzzer 12 to sound an alarm, reminding the staff to manually adjust the tension of the microfiber suede. The above is the working principle of this differential roller kneading type microfiber suede finishing machine.
