Abstract
Description
Technical Field
[0001] This invention relates to the field of leather stretching technology, specifically to a leather stretching machine with a drying function. Background Technology
[0002] Leather is the modified, non-perishable animal hide obtained through physical and chemical processing such as hair removal and tanning. It is composed of tightly woven natural protein fibers in three-dimensional space, with a special grain layer on its surface, possessing natural grain and luster, and a comfortable feel. In leather processing, to facilitate subsequent processing, animal hides are typically cut into specified shapes, increasing the leather area and making it flat. After tanning, dyeing, and processing with a leather stretching machine, the wet leather is stretched and flattened using a stretching machine, and then dried with hot air through multiple sets of steam fins on the stretching machine. After spraying and finishing processes, it also requires hot air drying using multiple sets of steam fins on a spraying machine.
[0003] Some leather stretching machines on the market have difficulty in quickly positioning and tightening leather during use, resulting in reduced tightening efficiency. They also have difficulty adjusting the tightening of leather of different sizes, which reduces the practicality of the device. Summary of the Invention
[0004] To achieve the above objectives, the present invention is implemented through the following technical solution: a leather stretching and stretching machine with a drying function, comprising a base plate, a support fixedly connected to the bottom of the base plate, a stretching device fixedly connected to the top of the base plate, a drying device fixedly connected to the top of the base plate on one side of the stretching device, and the stretching device being positioned below the drying device. The straightening device includes a fixed base, a first motor fixedly connected to the bottom of the fixed base, an arc-shaped sliding groove on the top of the fixed base, a straightening top plate fixedly connected to the drive shaft of the first motor, a straight sliding groove on the top of the straight sliding groove, a fixing component slidably connected to the inner wall of the straight sliding groove, a drying device fixedly connected to the bottom of the fixed base, and the bottom of the fixed base fixedly connected to the top of the equipment base plate via a bracket.
[0005] Preferably, the fixing assembly includes a fixing base plate, a fixing rod fixedly connected to the bottom of the fixing base plate, a limiting slide bar fixedly connected to the side of the fixing base plate, a fixing groove formed on the top of the fixing base plate, a fixing bracket fixedly connected to the top of the fixing base plate, a spring slide rod fixedly connected to the top of the inner wall of the fixing bracket, a movable plate sleeved and slidably connected to the side of the spring slide rod, a positioning plate adapted to the fixing groove fixedly connected to the side of the movable plate, an elastic component fixedly connected to the side of the fixing bracket, the fixing rod extending into the interior of the arc-shaped slide groove and slidably connected to the inner wall of the arc-shaped slide groove, and the fixing base plate slidably connected to the inner wall of the straight slide groove through the limiting slide bar.
[0006] Preferably, the elastic component includes a connecting base plate, a lower spring sheet fixedly connected to the bottom side of the connecting base plate, a lower fixing plate fixedly connected to the side of the lower spring sheet away from the connecting base plate, a lower positioning block rotatably connected to the top of the lower fixing plate via a pivot, an upper spring sheet fixedly connected to the side of the connecting base plate above the lower spring sheet, an upper fixing plate fixedly connected to the end of the upper spring sheet away from the connecting base plate, a spring sliding shaft slidably connected to the top of the upper fixing plate, an upper positioning block fixedly connected to the bottom of the spring sliding shaft, a driving plate fixedly connected to the top of the spring sliding shaft, and a side of the connecting base plate fixedly connected to the side of the fixing bracket.
[0007] Preferably, the drying device includes a ventilation pipe, a fan bracket is fixedly connected to the inner wall of the ventilation pipe, an air filter is fixedly connected to the bottom of the fan bracket, a second motor is fixedly connected to the bottom of the fan bracket, and a drying assembly is fixedly connected to the drive shaft of the second motor. A through hole is provided on the top side of the ventilation pipe, and the top of the ventilation pipe is fixedly connected to the bottom of the fixed base. When the raw material is clamped, the moving plate moves, compressing the spring slide rod. The compression of the spring slide rod generates a thrust on the moving plate, thereby driving the positioning plate and the fixing groove to engage, thus fixing the raw material. The moving plate moves, driving the upper positioning block to move. After the raw material is placed in, it descends under the elastic force of the spring slide rod, causing the upper positioning block and the lower positioning block to move inwards. The material is fixed by meshing. During the movement of the fixed base plate, the upper positioning block, the driving plate, the fixed groove, and the positioning plate work together to move the edge of the material, thereby straightening and stretching the material at multiple angles. The fixed groove and the positioning plate stretch the material vertically, while the driving plate and the upper positioning block work together to stretch the material in multiple directions. The rotation between the lower positioning block and the lower fixed plate, as well as the rotation between the spring slide shaft and the upper fixed plate, allows for adaptive adjustment during stretching. The rotation prevents wrinkles from forming when the material is clamped asymmetrically. At the same time, the elastic design of the upper and lower spring plates allows for elastic stretching of the material, thus avoiding tearing caused by hard contact during straightening, thereby improving the straightening quality and processing efficiency.
[0008] Preferably, the drying assembly includes a fixed shaft, a reversing bevel gear rotatably connected to the side of the fixed shaft, a lower bevel gear ring meshing with the bottom of the reversing bevel gear, a fan blade fixedly connected to the bottom of the lower bevel gear ring, an upper bevel gear ring meshing with the top of the reversing bevel gear, a heating tube fixedly connected to the top of the upper bevel gear ring, the bottom of the fan blade being fixedly connected to the drive shaft of a second motor, and the top of the fixed shaft being fixedly connected to the top of the inner wall of the ventilation pipe via a bracket.
[0009] Preferably, the drying device includes a drying support, the top of which is fixedly connected to the fixed end of a first hydraulic rod, the top of which is fixedly connected to a contact pad, the side of which is connected to a reversing pipe, the end of which is away from the first hydraulic rod being connected to a second hydraulic rod, the movable end of which is fixedly connected to a drying component, the bottom of which is fixedly connected to the top of the equipment base plate, and the drying component being positioned above the fixed base.
[0010] Preferably, the drying assembly includes a fan motor, a fan blade sleeve fixedly connected to the rotating part of the fan motor, straight fan blades fixedly connected to the side of the fan blade sleeve, a diffuser fan blade fixedly connected to the bottom of the straight fan blade, and a reinforcing fan blade fixedly connected to the bottom of the diffuser fan blade. The fixed part of the fan motor is fixedly connected to the movable end of the second hydraulic rod. The straight fan blade is positioned above the fixed base. The rotating part of the fan motor drives the fan blade sleeve to rotate, which in turn drives the straight fan blade to rotate. The straight fan blade drives the diffuser fan blade to rotate, which in turn drives the reinforcing fan blade to rotate. During rotation, air flows across the surface of the fan blade sleeve, thereby drying the top of the raw material. The straight design of the straight fan blade drives the air from top to bottom, and some of the air is diffused along the surface of the straight fan blade and across the surface of the diffuser fan blade, thus avoiding limited blowing at a single position on the top of the raw material. The reinforcing fan blade further enhances the air guided by the diffuser fan blade. Strong diffusion increases the air pressure on the top of the raw material, and the diffusion effect of the diffuser blades enhances the drying effect on the surface of the raw material. When the raw material is placed on top of the taut top plate, the bottom of the raw material contacts the top of the contact pad. The weight of the raw material presses the contact pad, thereby driving the movable end of the first hydraulic rod to descend. The descent of the movable end of the first hydraulic rod causes the hydraulic oil inside the fixed end of the first hydraulic rod to reach the interior of the second hydraulic rod through the deformation of the reversing pipe. This drives the movable end of the second hydraulic rod to descend, which in turn drives the fan motor to descend, thus generating different air pressures on the top of the raw material. The air pressure is automatically adjusted according to different raw materials. For thicker raw materials, the movable end of the second hydraulic rod drives the fan motor to descend, thereby generating greater air pressure on the top of the raw material, thereby increasing the drying and cooling speed and avoiding thermal deformation caused by overheating of the material. When the raw material is thinner, the air pressure is automatically reduced to avoid uneven temperature between the top and bottom due to excessive air pressure, resulting in incomplete drying.
[0011] This invention provides a leather stretching and stretching machine with a drying function. It has the following beneficial effects: 1. This leather stretching and tightening machine with drying function is equipped with a first motor. The drive shaft of the first motor drives the stretching top plate and the fixed base to rotate relative to each other, thereby driving multiple sets of fixed components to move synchronously, thus stretching the raw material at multiple angles. The stretching is completed by the top plane of the stretching top plate, and the material is stretched evenly at multiple angles through a single drive source, thus achieving uniform stretching of the raw material. Compared with the traditional combination of multiple fixed devices, reducing the number of fixed components is beneficial for checking the tension, thereby improving processing efficiency.
[0012] 2. This leather stretching and tightening machine with drying function is equipped with a moving plate. The movement of the moving plate compresses the spring slide rod, and the compression of the spring slide rod generates a thrust on the moving plate, thereby driving the positioning plate and the fixing groove to engage, thus fixing the raw material. The moving plate drives the upper positioning block to move. After the raw material is placed in, it descends under the elastic force of the spring slide rod, driving the upper positioning block and the lower positioning block to engage, thereby fixing the raw material. During the movement of the fixing base plate, the upper positioning block, the moving plate, the fixing groove and the positioning plate work together to drive the edge of the raw material to move, thereby straightening and stretching the raw material at multiple angles.
[0013] 3. This leather stretching and straightening machine with drying function is equipped with a fixed groove and a positioning plate for vertical stretching. It drives the plate and the upper positioning block to stretch in multiple directions. Through the rotation between the lower positioning block and the lower fixed plate, and the rotation between the spring slide shaft and the upper fixed plate, it can adaptively adjust during stretching. The rotation avoids wrinkles caused by asymmetrical clamping of the raw material. At the same time, the elastic design of the upper and lower spring plates allows for elastic stretching of the raw material, thereby avoiding tearing of the raw material due to hard contact during straightening, thus improving the straightening quality and processing efficiency.
[0014] 4. This leather stretching and tightening machine with drying function is equipped with a second motor. The drive shaft of the second motor drives the fan blades to rotate, which in turn drives the lower bevel gear ring to rotate. The lower bevel gear ring drives the reversing bevel gear to rotate, which in turn drives the upper bevel gear ring to rotate. The upper bevel gear ring then drives the heating tube to rotate, which heats the air. The fan blades expel the hot air, thus drying the bottom of the raw material. Simultaneously, the heating tube rotates in the opposite direction to the fan blades, increasing the cooling rate of the heating tube and achieving faster heating while maintaining a constant temperature. Furthermore, the rotation of the heating tube throws impurities generated during drying and stretching away from its surface, preventing carbonization of impurities on the heating tube surface and thus avoiding drying quality problems. Impurities are also discharged along the inner wall of the through-holes under the combined action of air pressure and the principle. The air filter filters the incoming air, preventing dusty air from being blown onto the bottom of the fabric.
[0015] 5. This leather stretching and stretching machine with drying function is equipped with a fan motor. The rotating part of the fan motor drives the fan blade sleeve to rotate, the fan blade sleeve to rotate, the straight fan blade to rotate, the straight fan blade to rotate, the diffuser fan blade to rotate, and the diffuser fan blade to rotate. During rotation, air flows over the surface of the fan blade sleeve, thereby driving the air to dry the top of the raw material. The straight design of the straight fan blade drives the air from top to bottom, and some of the air is diffused along the surface of the straight fan blade and over the surface of the diffuser fan blade, thereby avoiding limited blowing on a single position on the top of the raw material.
[0016] 6. This leather stretching and stretching machine with drying function is equipped with a contact pad. The bottom of the raw material contacts the top of the contact pad. The weight of the raw material presses the contact pad, thereby driving the movable end of the first hydraulic rod to descend. The descent of the movable end of the first hydraulic rod causes the hydraulic oil inside the fixed end of the first hydraulic rod to reach the interior of the second hydraulic rod through the deformation of the reversing pipe. This drives the movable end of the second hydraulic rod to descend, which in turn drives the fan motor to descend, thereby generating different air pressures on the top of the raw material. The air pressure is automatically changed according to different raw materials. Attached Figure Description

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0020] Please see Figures 1-2 The present invention provides a technical solution: a leather stretching and stretching machine with drying function, including a base plate 1, a support frame 2 fixedly connected to the bottom of the base plate 1, a stretching device 3 fixedly connected to the top of the base plate 1, and a drying device 4 fixedly connected to the top of the base plate 1 on one side of the stretching device 3. The stretching device 3 is located below the drying device 4.
[0021] The equipment base plate 1 and equipment support 2 provide overall support for the equipment. The straightening device 3 fixes and straightens the raw material and makes fine adjustments through elastic components to automatically adapt to different raw material tensile properties, thereby straightening the raw material in multiple directions. This completes the stretching and straightening of the raw material. By heating and blowing the bottom of the raw material, it is dried from the bottom. Compared with traditional heating methods, it reduces the problem of slow heat penetration caused by the thickness of the material. The drying device 4 dissipates heat from the top of the raw material, thereby circulating the heated air and driving the hot air to dry.
[0022] The straightening device 3 includes a fixed base 301, a first motor 302 fixedly connected to the bottom of the fixed base 301, an arc-shaped sliding groove 303 opened on the top of the fixed base 301, a straightening top plate 304 fixedly connected to the drive shaft of the first motor 302, a straight sliding groove 305 opened on the top of the straight sliding groove 304, a fixing component 306 slidably connected to the inner wall of the straight sliding groove 305, a drying device 307 fixedly connected to the bottom of the fixed base 301, and the bottom of the fixed base 301 fixedly connected to the top of the equipment base plate 1 through a bracket.
[0023] The first motor 302 is started, and the drive shaft of the first motor 302 drives the straightening top plate 304 and the fixed base 301 to rotate relative to each other, thereby driving multiple sets of fixed components 306 to move synchronously, thus stretching the raw material at multiple angles. The material is straightened by the plane at the top of the straightening top plate 304. The material is stretched evenly at multiple angles by a single drive source, thus achieving uniform straightening of the raw material. Compared with the cooperation of multiple fixed devices in the past, reducing the number of fixed components is beneficial for checking the tension, thereby improving processing efficiency.
[0024] Please see Figures 1-4 The present invention provides a technical solution: the fixing component 306 includes a fixing base plate 3061, a fixing rod 3062 fixedly connected to the bottom of the fixing base plate 3061, a limiting slide bar 3063 fixedly connected to the side of the fixing base plate 3061, a fixing groove 3064 formed on the top of the fixing base plate 3061, a fixing bracket 3065 fixedly connected to the top of the fixing base plate 3061, and a spring slide bar 3066 fixedly connected to the top of the inner wall of the fixing bracket 3065. A movable plate 3067 is sleeved and slidably connected to the side of the slide rod 3066. A positioning plate 3068 adapted to the fixed groove 3064 is fixedly connected to the side of the movable plate 3067. An elastic component 3069 is fixedly connected to the side of the fixed bracket 3065. The fixed rod 3062 extends into the interior of the arc-shaped slide groove 303 and is slidably connected to the inner wall of the arc-shaped slide groove 303. The fixed base plate 3061 is slidably connected to the inner wall of the straight slide groove 305 through the limiting slide strip 3063.
[0025] The elastic component 3069 includes a connecting base plate 30691. A lower spring plate 30692 is fixedly connected to the bottom side of the connecting base plate 30691. A lower fixing plate 30693 is fixedly connected to the side of the lower spring plate 30692 away from the connecting base plate 30691. A lower positioning block 30694 is rotatably connected to the top of the lower fixing plate 30693 via a pivot. An upper spring plate is fixedly connected to the side of the connecting base plate 30691 above the lower spring plate 30692. The upper spring plate 30695 is fixedly connected to an upper fixing plate 30696 at one end away from the connecting base plate 30691. The top of the upper fixing plate 30696 is slidably connected to a spring slide shaft 30697. The bottom of the spring slide shaft 30697 is fixedly connected to an upper positioning block 30698. The top of the spring slide shaft 30697 is fixedly connected to a driving plate 30699. The side of the connecting base plate 30691 is fixedly connected to the side of the fixing bracket 3065.
[0026] When the raw material is clamped, the moving plate 3067 moves, compressing the spring slide rod 3066. This compression generates a thrust on the moving plate 3067, causing the positioning plate 3068 and the fixing groove 3064 to engage, thus fixing the raw material. The moving drive plate 30699 moves, causing the upper positioning block 30698 to move. After the raw material is placed in, it descends under the elastic force of the spring slide rod 30697, causing the upper positioning block 30698 to engage with the lower positioning block 30694, thus fixing the raw material. During the movement of the fixing base plate 3061, the upper positioning block 30698 and the drive plate 30699, as well as the fixing groove 3064 and the positioning plate 3068, engage in a coordinated action. The material is moved along its edge, thus straightening and stretching it at multiple angles. The fixed groove 3064 and the positioning plate 3068 stretch it vertically, driving the plate 30699 and the upper positioning block 30698 to stretch it in multiple directions. Through the rotation between the lower positioning block 30694 and the lower fixed plate 30693, and the rotation between the spring slide shaft 30697 and the upper fixed plate 30696, adaptive adjustment is made during stretching. Rotation avoids wrinkles in the material when it is clamped asymmetrically. At the same time, the elastic design of the upper spring plate 30695 and the lower spring plate 30692 allows for elastic stretching of the material, thus avoiding tearing of the material due to hard contact during straightening, thereby improving the straightening quality and processing efficiency.
[0027] Please see Figures 1-6The present invention provides a technical solution: the drying device 307 includes a ventilation pipe 3071, a fan bracket 3072 is fixedly connected to the inner wall of the ventilation pipe 3071, an air filter element 3073 is fixedly connected to the bottom of the fan bracket 3072, a second motor 3074 is fixedly connected to the bottom of the fan bracket 3072, a drying component 3075 is fixedly connected to the drive shaft of the second motor 3074, a through hole 3076 is opened on the top side of the ventilation pipe 3071, and the top of the ventilation pipe 3071 is fixedly connected to the bottom of the fixed base 301.
[0028] The drying assembly 3075 includes a fixed shaft 30751, a reversing bevel gear 30752 rotatably connected to the side of the fixed shaft 30751, a lower bevel gear ring 30753 meshing with the bottom of the reversing bevel gear 30752, a fan blade 30754 fixedly connected to the bottom of the lower bevel gear ring 30753, an upper bevel gear ring 30755 meshing with the top of the reversing bevel gear 30752, a heating tube 30756 fixedly connected to the top of the upper bevel gear ring 30755, the bottom of the fan blade 30754 fixedly connected to the drive shaft of the second motor 3074, and the top of the fixed shaft 30751 fixedly connected to the top of the inner wall of the ventilation pipe 3071 via a bracket.
[0029] The second motor 3074 is started. The drive shaft of the second motor 3074 drives the fan blade 30754 to rotate. The fan blade 30754 drives the lower bevel gear ring 30753 to rotate. The lower bevel gear ring 30753 drives the reversing bevel gear 30752 to rotate. The reversing bevel gear 30752 drives the upper bevel gear ring 30755 to rotate. The upper bevel gear ring 30755 drives the heating tube 30756 to rotate. The heating tube 30756 heats the air. The fan blade 30754 exhausts the hot air, thereby drying the bottom of the raw material. At the same time, the heating tube 30756 and the fan blade 30754... The rotation direction of 0754 is opposite, thereby increasing the cooling rate of heating tube 30756 and achieving a faster heating rate while maintaining a constant temperature. The rotation of heating tube 30756 also throws impurities generated during drying and straightening away from the surface of heating tube 30756, thus avoiding drying quality problems caused by the carbonization of impurities on the surface of heating tube 30756. Furthermore, under the combined action of air pressure and principle, impurities are discharged along the inner wall of through hole 3076. Air filter element 3073 filters the introduced air, thereby preventing dusty air from being blown onto the bottom of the fabric.
[0030] Please see Figures 1-8The present invention provides a technical solution: the drying device 4 includes a drying support 401, the top of the drying support 401 is fixedly connected to the fixed end of the first hydraulic rod 402, the top of the movable end of the first hydraulic rod 402 is fixedly connected to the contact pad 404, the side of the fixed end of the first hydraulic rod 402 is connected to a reversing pipe 405, the end of the reversing pipe 405 away from the first hydraulic rod 402 is connected to a second hydraulic rod 406, the movable end of the second hydraulic rod 406 is fixedly connected to a drying component 407, the bottom of the drying support 401 is fixedly connected to the top of the equipment base plate 1, and the drying component 407 is disposed above the fixed base 301.
[0031] The drying assembly 407 includes a fan motor 4071, a fan blade sleeve 4072 fixedly connected to the rotating part of the fan motor 4071, a straight fan blade 4073 fixedly connected to the side of the fan blade sleeve 4072, a diffuser fan blade 4074 fixedly connected to the bottom of the straight fan blade 4073, a reinforcing fan blade 4075 fixedly connected to the bottom of the diffuser fan blade 4074, a fixed part of the fan motor 4071 fixedly connected to the movable end of the second hydraulic rod 406, and the straight fan blade 4073 is positioned above the fixed base 301.
[0032] The fan motor 4071 is started. The rotating part of the fan motor 4071 drives the fan blade sleeve 4072 to rotate. The rotation of the fan blade sleeve 4072 drives the straight fan blade 4073 to rotate. The straight fan blade 4073 drives the diffuser fan blade 4074 to rotate. The diffuser fan blade 4074 drives the reinforcing fan blade 4075 to rotate. During rotation, air flows over the surface of the fan blade sleeve 4072, thereby driving the air to dry the top of the raw material. The straight design of the straight fan blade 4073 drives the air from top to bottom, and some of the air is diffused along the surface of the straight fan blade 4073 and over the surface of the diffuser fan blade 4074, thus avoiding limited blowing to a single position on the top of the raw material. The reinforcing fan blade 4075 enhances the diffusion of the air guided by the diffuser fan blade 4074, thereby increasing the air pressure on the top of the raw material. Combined with the diffusion effect of the diffuser fan blade 4074, the drying effect on the surface of the raw material is enhanced. The raw material is placed on the taut top plate. When the material is at the top of 304, the bottom of the material contacts the top of the contact pad 404. The weight of the material presses against the contact pad 404, causing the movable end of the first hydraulic rod 402 to descend. The descent of the movable end of the first hydraulic rod 402 causes the hydraulic oil inside the fixed end of the first hydraulic rod 402 to reach the interior of the second hydraulic rod 406 through the deformation of the reversing pipe 405. This drives the movable end of the second hydraulic rod 406 to descend, which in turn drives the fan motor 4071 to descend, thereby generating different air pressures on the top of the material. The air pressure is automatically adjusted according to different materials. For thicker materials, the movable end of the second hydraulic rod 406 drives the fan motor 4071 to descend, thereby generating greater air pressure on the top of the material, increasing the drying and cooling speed and preventing thermal deformation caused by overheating. When the material is thinner, the air pressure is automatically reduced to avoid uneven temperature between the top and bottom due to excessive air pressure, resulting in incomplete drying.
[0033] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in the present invention, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
