Description

Technical Field

[0001] This utility model relates to the field of microfiber leather processing technology, and in particular to a microfiber leather tanning machine. Background Technology

[0002] Microfiber leather, also known as microfiber leather, is a synthetic material primarily composed of microfiber and polyurethane (PU), manufactured using advanced technology. It is widely used in fashion, footwear, furniture, and automotive interiors, and is hailed as a green material for the new century. The processing of microfiber leather requires a rubbing process, necessitating the use of specialized rubbing equipment.

[0003] Chinese utility model patent CN218521273U discloses a microfiber leather tanning machine. This device incorporates a tanning mechanism inside the machine, using clamping blocks to hold the leather in place, preventing multiple pieces of leather from becoming entangled during the tanning process. The leather is held in place by sliding blocks that can slide and extend within the rotating disc, allowing multiple first tanning balls to tan the leather simultaneously. This facilitates tanning multiple pieces of leather at the same time and allows for tanning of various parts of the leather. Regarding the aforementioned technology, the inventors believe the following drawbacks exist:

[0004] In practical use, in order to ensure the thorough kneading of microfiber leather, the position of the microfiber leather needs to be frequently adjusted, which is not only troublesome but also reduces the processing efficiency of microfiber leather, thus reducing the practicality of the device. Therefore, we provide a microfiber leather kneading machine. Utility Model Content

[0005] To address the problem in the aforementioned background technology that frequent adjustments to the position of microfiber leather are not only cumbersome but also reduce processing efficiency, this invention provides a microfiber leather kneading machine.

[0006] This utility model is achieved by the following technical solution: a microfiber leather tanning machine, including a base, a tanning component and a cleaning component. The two sides of the base are respectively rotatably connected to a take-up roller and a release roller via brackets. A stepper motor is fixedly connected to one side of the bracket, and the rotor end of the stepper motor is coaxially fixedly connected to one end of the take-up roller.

[0007] The kneading assembly includes a roller rotatably connected to the top of a base via a fixed seat. A rotary motor is fixedly connected to the fixed seat, and the rotor end of the rotary motor is coaxially fixedly connected to one end of the roller. A fixed frame is equidistantly circumferentially fixed to the outside of the roller. A movable plate is slidably connected inside the fixed frame, and the end of the movable plate extends to the outside of the fixed frame. A striking head is fixedly connected to the end of the movable plate. Annular guide rails are fixedly connected to both sides of the top of the base via fixed brackets. Connecting brackets are fixedly connected to both sides of the movable plate. Ball bearings are movably connected to the end of the connecting brackets, and the ball bearings contact the inner surface of the annular guide rails.

[0008] The cleaning assembly includes two sets of scrapers mounted on the base. Two sets of guide blocks are symmetrically fixedly connected to the top of the scrapers. Two sets of guide rods are fixedly connected to the top of the base via a connecting seat, and the guide rods are slidably connected to the two sets of guide blocks on the same side. Springs are symmetrically sleeved on the outside of the guide rods. A push plate is also mounted on the top of the base. A connecting rod is hinged between the push plate and the scrapers via a hinge.

[0009] As a further improvement to the above solution, brackets are fixedly connected to both sides of the top of the base, an electric push rod is fixedly connected to the top of the brackets, a mounting base is fixedly connected to the telescopic end of the electric push rod, and a pressure roller is rotatably connected to the mounting base.

[0010] As a further improvement to the above solution, a movable groove is provided on the fixed frame at the position corresponding to the connecting bracket.

[0011] As a further improvement to the above solution, a notch is provided at the lowest point of the annular guide rail, and one side of the notch is designed as a slope.

[0012] As a further improvement to the above solution, the end of the striking head is designed with an arc shape.

[0013] As a further improvement to the above solution, the two ends of the spring are fixedly connected to the guide block and the connecting seat, respectively.

[0014] As a further improvement to the above solution, a pressure plate is provided above the base, and a connecting rod is hinged between the pressure plate and the scraper through a hinge.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model uses a rotary motor to drive the roller to rotate, which in turn drives the striking head to make a circular motion. At this time, the ball bearings on the connecting frame will roll on the annular guide rail. When the ball bearings roll to the notch on the annular guide rail, the sliding cooperation between the fixed frame and the movable plate, along with the gravity acting on the striking head itself, causes the striking head to automatically descend and strike the microfiber leather, thereby achieving the purpose of automatic leather kneading. In addition, the stepper motor intermittently drives the winding roller to rotate to wind up the microfiber leather, ensuring the thoroughness of the kneading of the microfiber leather. This not only improves the automation of the device but also speeds up the processing efficiency of microfiber leather, making it highly practical.

[0017] 2. In the process of driving the striking head to make a circular motion, when the striking head contacts the push plate, as the striking head continues to move, it can push the push plate to move together. Utilizing the sliding cooperation between the guide block and the guide rod, and the hinged cooperation between the scraper and the push plate and the connecting rod, it can push the two sets of scrapers to move simultaneously from the middle to both sides, thereby scraping away the debris and dust generated and falling on the microfiber leather during the kneading process, thus ensuring the processing quality of the microfiber leather and further improving the practicality of the device.

Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. Example 1:

[0025] Please combine Figure 1-4 This embodiment of a microfiber leather tanning machine includes a base 1. A take-up roller 2 and an unwind roller 3 are rotatably connected to both sides of the base 1 via brackets. A stepper motor is fixedly connected to one side of the bracket, and the rotor end of the stepper motor is coaxially fixedly connected to one end of the take-up roller 2. Brackets are fixedly connected to both sides of the top of the base 1. An electric push rod 4 is fixedly connected to the top of the brackets. A mounting seat is fixedly connected to the telescopic end of the electric push rod 4. A pressure roller 5 is rotatably connected to the mounting seat to facilitate tensioning of the microfiber leather and prevent it from loosening.

[0026] A leather-rubbing assembly for rubbing microfiber leather includes a roller 101 rotatably connected to the top of a base 1 via a fixed seat. A rotary motor is fixedly connected to the fixed seat, and the rotor end of the rotary motor is coaxially fixedly connected to one end of the roller 101. A fixed frame 102 is equidistantly circumferentially fixedly connected to the outside of the roller 101. A movable plate 103 is slidably connected inside the fixed frame 102, and the end of the movable plate 103 extends to the outside of the fixed frame 102. A striking head 104 is fixedly connected to the end of the movable plate 103. Both sides of the top of the base 1 are fixedly connected to the annular guide rail 105 by the fixing bracket. Both sides of the movable plate 103 are fixedly connected to the connecting bracket 106. The end of the connecting bracket 106 is movably connected to the ball 107 and the ball 107 contacts the inner side of the annular guide rail 105. The fixed frame 102 is provided with a movable groove corresponding to the position of the connecting bracket 106 to facilitate the movement of the connecting bracket 106. The lowest point of the annular guide rail 105 is provided with a notch. One side of the notch is designed as a slope. The end of the striking head 104 is designed as an arc structure.

[0027] A cleaning assembly for cleaning the surface of microfiber leather includes two scrapers 201 set above a base 1. Two sets of guide blocks 202 are symmetrically fixedly connected to the top of the scrapers 201. Two sets of guide rods 203 are fixedly connected to the top of the base 1 through a connecting seat, and the guide rods 203 are slidably connected to the two sets of guide blocks 202 on the same side. Springs 204 are symmetrically sleeved on the outside of the guide rods 203. A push plate 205 is also set above the base 1. A connecting rod 206 is hinged between the push plate 205 and the scrapers 201 through a hinge. The two ends of the springs 204 are fixedly connected to the guide blocks 202 and the connecting seat, respectively.

[0028] The implementation principle of a microfiber leather tanning machine in this application embodiment is as follows: First, one end of the microfiber leather is wound around the take-up roller 2. Then, the electric push rod 4 is activated to push the pressure roller 5 vertically downward to tension the microfiber leather and make it straight. Subsequently, the rotary motor and the stepper motor are activated. The rotary motor drives the roller 101 to rotate, which drives the striking head 104 to make a circular motion. At this time, the ball bearings 107 on the connecting frame 106 will roll on the annular guide rail 105. When the ball bearings 107 roll to the annular guide rail... When the notch on 105 is reached, the sliding engagement between the fixed frame 102 and the movable plate 103, along with the gravity acting on the striking head 104, causes it to automatically descend and strike the microfiber leather, thus achieving automatic leather kneading. As the roller 101 continues to rotate, the balls 107 on the connecting frame 106 will roll back along the inclined surface of the notch to the surface of the annular guide rail 105, thereby resetting the striking head 104. This, combined with the intermittent driving of the take-up roller by the stepper motor, further facilitates the automatic kneading of the leather. 2. Rotation is used to roll up the microfiber leather, ensuring thorough kneading. This not only improves the automation of the device but also speeds up the processing efficiency of the microfiber leather. Simultaneously, as the striking head 104 rotates in a circular motion, when it contacts the push plate 205, its continued movement pushes the push plate 205 to move as well. Utilizing the sliding engagement between the guide block 202 and the guide rod 203, and the hinged engagement between the scraper 201 and the push plate 205 and the connecting rod 206, both sets of scrapers 201 are pushed simultaneously from the center to both sides. This removes the debris and dust generated and falling onto the microfiber leather during kneading, thus ensuring the processing quality of the microfiber leather. At this time, the spring 204 is compressed. When the striking head 104 rotates away from the push plate 205, the spring 204's own rebound action causes both sets of scrapers 201 to automatically return to their original positions. Finally, the kneading operation is completed for all the microfiber leather. Example 2:

[0029] Based on Embodiment 1, this embodiment further improves upon the following: a pressure plate 2001 is provided above the base 1. The pressure plate 2001 and the scraper 201 are hinged together by a connecting rod 2002. By pressing the pressure plate 2001 and sliding between the guide block 202 and the guide rod 203, the pressure plate 2001 and the scraper 201 are hinged together with the connecting rod 2002, which allows the two sets of scrapers 201 to move further from the middle to both sides at the same time. This facilitates cleaning of microfiber leather with a larger width, thereby ensuring thorough cleaning. Furthermore, the time interval between the intermittent rotation of the stepper motor-driven take-up roller 2 is sufficient to operate the pressure plate 2001 to drive the scraper 201 to move.

[0030] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
