Description

Technical Field

[0001] This utility model relates to the field of leather measurement technology, specifically a thickness measuring device for leather processing. Background Technology

[0002] Leather is a basic material used in our daily lives to make clothing. As a raw material, the quality of leather determines the lifespan of the product. Therefore, leather needs to be measured after it is manufactured.

[0003] Existing methods for measuring leather thickness still rely on manual measurement, which involves using calipers and clamps to measure the leather point by point, and then manually reading and recording the measurements. This method is inefficient, has a large error, and requires manual point-by-point measurement, which is time-consuming and labor-intensive. Therefore, a thickness measuring device for leather processing is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a thickness measuring device for leather processing, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: It includes a base plate, with upright plates connected to both sides of the top of the base plate. Each of the two upright plates has a mounting groove on both sides of its top. A mounting frame is connected inside each mounting groove. An upper drive roller and a lower drive roller are rotatably mounted between the two mounting frames. Gears are connected to the surfaces of the rotating shafts of the upper and lower drive rollers, and the two gears mesh with each other. An L-shaped support frame is connected to one side of each of the two upright plates. A unwinding rod is rotatably mounted on one side of one of the L-shaped support frames, and the other end of the unwinding rod is slidably mounted on the other side of the L-shaped support frame. A support frame is connected to the middle section of the top of the upright plate. A measuring mechanism is connected to the top of the support frame. A display screen is connected to one side of the support frame. A support plate is connected to one side of one of the upright plates. A motor is connected to the top of the support plate. The output end of the motor passes through one side of the upright plate and is connected to a rotating plate.

[0006] Preferably, four winding rods are connected to one side of the rotating plate, and multiple connecting plates are connected between the four winding rods.

[0007] Preferably, pulleys are connected to both the surface of the motor output end and the surface of the upper drive roller shaft near the winding rod, and a drive belt is sleeved between the two pulleys.

[0008] Preferably, the measuring mechanism includes an electric actuator connected to the top of a support frame and a base connected to the top of a base plate. A lower support plate is connected to the top of the base. A top plate is connected to the output end of the electric actuator. The output end of the electric actuator passes through the top plate and is connected to a protective shell. An upper displacement sensor is connected to both the protective shell and the lower support plate. Slide rods are connected to both sides of the bottom of the top plate. A lower pressure plate is connected to the bottom of the slide rods. Springs are sleeved on the surface of the slide rods at the bottom of the top plate and the top of the lower pressure plate. The other ends of the two slide rods pass through the top plate and are connected to a limit plate.

[0009] Preferably, a silicone layer is connected to the bottom end of the lower pressure plate, and through holes are opened on the surface of the lower pressure plate and the corresponding protective shell of the silicone layer.

[0010] Preferably, multiple guide rods are connected to both the lower pressure plate and one side of the silicone layer, and the bottom surface of the guide rods is at the same level as the bottom of the silicone layer.

[0011] Preferably, the two upper displacement sensors are electrically connected to the display screen, and the two upper displacement sensors are arranged opposite each other, with the output terminals of the two upper displacement sensors at the same vertical level.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting two upper displacement sensors relative to each other, the positions of the upper and lower surfaces of the leather can be measured simultaneously, and the thickness of the leather can be obtained by calculating the difference between the two. This differential measurement method can effectively eliminate errors caused by uneven placement of the leather or tilting of the device itself, and improve measurement accuracy. Through the coordinated work of the motor, electric actuator, sensor and display screen, the measurement process can be automated or semi-automated, reducing the labor intensity of operators and improving measurement efficiency.

[0017] 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.

[0018] Please see Figures 1-3 This utility model provides a technical solution, including a base plate 1, with upright plates 2 connected to both sides of the top of the base plate 1. Mounting grooves 3 are opened on both sides of the top of the two upright plates 2, and mounting frames 4 are connected inside the mounting grooves 3. An upper transmission roller 5 and a lower transmission roller 6 are rotatably mounted between the two mounting frames 4. Gears 7 are connected to the surfaces of the rotating shafts of the upper transmission roller 5 and the lower transmission roller 6, and the two gears 7 mesh with each other. An L-shaped support frame 8 is connected to one side of each of the two upright plates 2. A unwinding rod 9 is rotatably mounted on one side of one of the L-shaped support frames 8, and the other end of the unwinding rod 9 is slidably mounted on the other side of the other L-shaped support frame 8. A support frame 10 is connected to the middle section of the top of the upright plate 2, and a measuring mechanism 11 is connected to the top of the support frame 10. A display screen 12 is connected to one side of the support frame 10. A support plate 13 is connected to one side of one of the upright plates 2, and a motor 14 is connected to the top of the support plate 13. The output end of the motor 14 passes through one side of the upright plate 2 and is connected to a rotating plate 15.

[0019] Four winding rods 16 are connected to one side of the rotating plate 15, and multiple connecting plates 17 are connected between the four winding rods 16. Their function is to rewind the leather after the measurement is completed.

[0020] Both the output end surface of the motor 14 and the shaft surface of the upper drive roller 5 near the take-up bar 16 are connected to pulleys 18. A drive belt 19 is sleeved between the two pulleys 18. Its function is to transmit the rotational motion of the motor 14 to the upper drive roller 5, thereby driving the upper drive roller 5 to rotate. The rotation of the upper drive roller 5 can be used to pull the leather forward, so that it can be measured by the thickness measuring device, and after the measurement is completed, it continues to move forward, and finally reaches the take-up bar 16 for winding.

[0021] The measuring mechanism 11 includes an electric actuator 111 connected to the top of the support frame 10 and a base 112 connected to the top of the base plate 1. A lower support plate 113 is connected to the top of the base 112. A top plate 114 is connected to the output end of the electric actuator 111. The output end of the electric actuator 111 passes through the top plate 114 and is connected to a protective shell 115. An upper displacement sensor 116 is connected inside both the protective shell 115 and the lower support plate 113. Sliding devices are connected to both sides of the bottom end of the top plate 114. The bottom end of the rod 117 is connected to a lower pressure plate 118. The bottom end of the top plate 114 and the top end of the lower pressure plate 118 are fitted with springs 119 on the surface of the rod 117. The other ends of the two rods 117 pass through the top plate 114 and are connected to a limit plate 120. The function of the limit plate 120 is to drive the top plate 114 and the lower pressure plate 118 to move relative to each other through the electric push rod 111, and to measure the distance between the top plate 114 and the lower support plate 113 using the upper displacement sensor 116, thereby obtaining the thickness of the leather.

[0022] A silicone layer 20 is connected to the bottom of the lower pressure plate 118. The lower pressure plate 118 and the silicone layer 20 are respectively provided with through holes 121 on the protective shell 115. The function of the silicone layer 20 is to provide a buffer layer when the lower pressure plate 118 applies pressure, so as to prevent the metal lower pressure plate from directly contacting the leather surface, preventing pressure damage, scratches or leaving indentations, thereby protecting the surface quality of the leather. In order to ensure that the upper displacement sensor 116 can directly measure the distance between the top plate 114 and the lower support plate 113, the interference of the silicone layer 20 on the measurement is eliminated, and the pressure is promoted to be evenly distributed and air is expelled, thereby improving the measurement accuracy.

[0023] Multiple guide rods 21 are connected to both the lower pressure plate 118 and the silicone layer 20 on one side. The bottom surface of the guide rod 21 is at the same level as the bottom of the silicone layer 20. The purpose of the guide rod 21 is to guide the leather into the measurement position, prevent the leather from shifting, and protect the leather edge.

[0024] Two upper displacement sensors 116 are electrically connected to the display screen 12, and the two upper displacement sensors 116 are arranged opposite each other with their output terminals at the same vertical level. The function of this symmetrical arrangement is to eliminate measurement deviations caused by installation position deviations or mechanical errors. By comparing the measurement data of the two sensors 116, the measurement results can be further verified and calibrated, thereby improving the accuracy and reliability of the measurement.

[0025] Working principle: The leather is released from the unwinding rod 9, passes between the upper drive roller 5 and the lower drive roller 6, passes through the measuring mechanism 11, and then passes between the upper drive roller 5 and the lower drive roller 6 again. The motor 14 starts, driving the upper drive roller 5 to rotate through the pulley 18 and the drive belt 19. The rotating drive rollers 5 and 6 clamp and pull the leather forward. The electric push rod 111 starts, pushing the top plate 114 downward. The top plate 114 drives the slide rod 117 below it to move downward together. The slide rod 117 passes through the lower pressure plate 118, compressing the spring 119 sleeved on the slide rod 117. When the silicone layer 20 at the bottom of the lower pressure plate 118 contacts the upper surface of the leather, the electric push rod 111 stops or continues to apply pressure at a set constant pressure. The spring 119 here plays a role in buffering and pressure regulation. During the holding function, the distance between the bottom surface of the top plate 114 or the bottom surface of the protective shell 115 and the top surface of the lower support plate 113 or the bottom surface of the lower pressure plate 118 / silicone layer 20 is the thickness of the leather. The displacement sensor 116 transmits the measured data to the display screen 12 through an electrical connection. The display screen 12 displays the thickness value of the leather. After the measurement is completed, the electric push rod 111 can retract, so that the lower pressure plate 118 is lifted by the action of the spring 119 and detaches from the leather. The transmission rollers 5 and 6 continue to pull the leather forward, so that it reaches the winding rod 16 on the rotating plate 15. The output end of the motor 14 is also connected to the rotating plate 15. Therefore, when the motor 14 drives the upper transmission roller 5, it also drives the rotating plate 15 and the winding rod 16 to rotate synchronously. The leather is evenly wound up by the winding rod 16.
