Abstract
Description
Technical Field
[0001] This utility model belongs to the field of leather processing technology, and specifically relates to a leather surface cleaning device for leather product manufacturing. Background Technology
[0002] In the leather production process, the leather surface needs to be cleaned. Traditional cleaning methods involve manual wiping, which is labor-intensive and inefficient. Current methods utilize mechanical cleaning equipment, which improves efficiency to some extent. However, existing equipment only cleans the front of the leather, resulting in incomplete cleaning. During later processing, dust, stains, and other impurities from the back may enter the front, affecting the quality of the leather products. Furthermore, since the leather is moved horizontally with its front side facing up during cleaning, impurities are difficult to remove quickly and effectively with water spray, leaving them adhering to the surface. This results in insufficient cleaning effectiveness and efficiency. Additionally, prolonged water retention on the leather surface can lead to seepage and damage. Therefore, overcoming these technical problems and shortcomings is a key issue that needs to be addressed. Utility Model Content
[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a leather surface cleaning device for leather product production that integrates spraying, brushing and air drying. This cleaning device cleans both the front and back of the leather body thoroughly. During the cleaning process, the front of the leather body moves horizontally forward, and the impurities brushed off can be quickly and effectively washed away with the water flow. This not only improves the cleaning effect and efficiency, but also avoids water remaining on the surface of the leather body for too long, which could damage the leather body.
[0004] The purpose of this utility model is achieved as follows: A leather surface cleaning device for leather product production includes a box body. The middle of the left side wall of the box body is provided with an inlet for the leather body to enter, and the middle of the right side wall of the box body is provided with an outlet for the leather body to exit. The front of the leather body is parallel to the front side of the box body. The box body is provided with a feeding mechanism, a guiding mechanism, a spraying mechanism, a brushing mechanism, and a drying mechanism. The guiding mechanism is located directly behind the feeding mechanism. The feeding mechanism and the guiding mechanism are in contact with the front and back of the leather body, respectively. There are two spraying mechanisms, two brushing mechanisms, and two drying mechanisms, which are symmetrically distributed about the leather body. The lower surface of the box body is funnel-shaped, and a discharge pipe is fixedly connected to the middle of the lower surface of the box body.
[0005] Furthermore, the feeding mechanism includes a driving roller and a driven roller parallel to the leather body. The driving roller is located to the right of the driven roller. Both the driving roller and the driven roller are in contact with the front surface of the leather body. The driving roller is fixedly connected to the outside of the driving shaft. The driving shaft is fixedly connected to the output end of a first motor. The first motor is mounted on the lower surface of a first fixed frame. The first fixed frame is fixedly connected to the upper surface of the housing. A driving wheel is fixedly connected to the driving shaft. The driving wheel is connected to a driven wheel via a belt. The driven wheel is fixedly connected to the driven shaft. The driven roller is fixed to the outside of the driven shaft. The lower end of the drive shaft is connected to the right support plate through a bearing seat, and the lower end of the driven shaft is connected to the left support plate through a bearing seat. The left support plate and the right support plate are fixed to the lower part of the inner wall on the left side and the lower part of the inner wall on the right side of the box, respectively. The drive shaft and the driven shaft are both connected to the upper side wall of the box through bearings. The first motor drives the drive shaft to rotate, which in turn drives the drive roller to rotate. Under the action of the belt, the driven roller rotates. The leather body is conveyed to the right through the drive roller and the driven roller, thus realizing the feeding.
[0006] Furthermore, the guiding mechanism includes two guiding rollers parallel to the leather body, one of which is located directly behind the driving roller and the other is located directly behind the driven roller. Both guiding rollers are in contact with the back of the leather body. The guiding rollers are rotatably connected to the mounting frame, which is fixedly connected to the inner rear wall of the housing. The rotation of the driving roller and the driven roller causes the two guiding rollers in contact with the back of the leather body to rotate. The arrangement of the guiding rollers allows the leather body to be conveyed horizontally to the right, thus playing a guiding role.
[0007] Furthermore, the spray washing mechanism includes two water distributors parallel to the leather body and symmetrically distributed about the front and back of the leather body. The two water distributors are located on the right side of the driven roller. The sides of the two water distributors closest to the leather body are uniformly fixed with liquid outlets. The middle of the sides of the two water distributors furthest from the leather body is fixed with water supply pipes. The two water supply pipes are connected to a water suction pipe through a T-joint. The other end of the water suction pipe is connected to the lower right side of the water tank. A water pump is installed on the water suction pipe. A water inlet is provided on the upper surface of the water tank. Water is introduced into the two water distributors through the water pump, water suction pipe, and water supply pipe. Finally, water is evenly sprayed onto the front and back of the leather body through the liquid outlets to wash away dust, stains, etc. on the front and back of the leather, achieving a cleaning effect.
[0008] Furthermore, a sealing plug is provided at the upper end of the water inlet to prevent impurities from entering the water tank through the water inlet and affecting the subsequent spraying effect.
[0009] Furthermore, the cleaning mechanism includes two mounting plates parallel to the leather body and symmetrically distributed about the front and back of the leather body. The two mounting plates are located on the right side of the water distributor and the left side of the drive roller. Brushes are uniformly fixed to the side of the mounting plates closest to the leather body, and rotating shafts are fixed to the center of the side of the mounting plates furthest from the leather body. The other ends of the two rotating shafts are respectively fixed to the output ends of two second motors. The two second motors are respectively mounted on the inner sides of two second fixed frames. The two second fixed frames are respectively fixed to the front and rear sides of the housing. The two rotating shafts are connected to the front and rear side walls of the housing through bearings. The mounting plates and brushes are rotated by the second motors and rotating shafts, and the stains adhering to the front and back of the leather body are brushed off by the brushes, improving the cleaning effect.
[0010] Furthermore, the brush is a soft-bristled brush to avoid damaging the leather body during the cleaning process.
[0011] Furthermore, the air-drying mechanism includes two air blowers parallel to the leather body and symmetrically distributed about the front and back of the leather body. The air blowers are located to the right of the drive roller. Air outlets are uniformly fixed to the side of the air blower closest to the leather body, and air inlet pipes are fixed to the middle of the side of the air blower furthest from the leather body. The two air inlet pipes are connected to air supply pipes through a T-joint. The other end of the air supply pipes is connected to a blower. The blower is fixed to the upper right side of the housing. The blower, air supply pipes, air blowers, and air outlets are used to blow air onto the washed leather body to dry it, preventing water from remaining on both sides of the leather body for a long time and damaging the leather body.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. The leather surface cleaning device of this utility model uses a first motor, a drive shaft, a drive wheel, a belt, a driven wheel, and a driven shaft to rotate the drive roller and the driven roller, causing the belt body to be conveyed to the right. During the conveying process, two guide rollers rotate. The arrangement of the drive roller, the driven roller, and the two guide rollers allows the leather body to be conveyed horizontally to the right, which is beneficial for spray washing, brushing, and air drying operations.
[0014] 2. The leather surface cleaning device of this utility model uses a water pump, a water pipe, and a water delivery pipe to allow water from the water tank to enter two water distributors. Water is then sprayed evenly onto the front and back of the leather body through the liquid outlet, washing away dust and stains from both sides of the leather body, thus achieving a cleaning effect. Because the front of the leather body is parallel to the front side of the box, dust and stains can be washed away vertically with the water flow. This not only quickly removes dust and stains but also prevents excessive water from seeping onto the front and back of the leather body, ensuring both cleaning effectiveness and preventing damage to the leather body.
[0015] 3. The leather surface cleaning device of this utility model uses a second motor and a rotating shaft to rotate the mounting plate and brush. The brush removes the stains adhering to the front and back of the leather body after spraying and washing, improving the cleaning effect. Then, a blower, air supply pipe, air distributor and air outlet are used to blow air on the washed leather body to dry it, avoiding damage to the leather body due to prolonged water on the front and back. In other words, this device integrates spraying, brushing and drying, which can improve the cleaning effect and efficiency. Attached Figure Description
