Description

Technical Field

[0001] The utility model relates to the technical field of drying devices, and particularly relates to a drying device for leather processing. Background Art

[0002] The leather industry is a traditional industry with a long history, and its products are widely used in multiple fields such as clothing, footwear, luggage, furniture, and automotive interiors. With the booming global economy and the upgrading of people's consumption concepts, leather products have won wide market favor with their unique texture, durability, and sense of fashion. In various fields, leather fabrics have become the preferred materials for high-end customization, fashion trends, and casual decoration with their unique texture and style. Whether it is an elegant leather coat, a fashionable leather jacket, or comfortable leather pants and skirts, they all showcase the infinite charm of leather products. And with the consumption upgrade and the increasing personalized needs, the demand for high-quality and high-value-added leather products is also growing continuously.

[0003] Traditional drying equipment is difficult to dry leather products comprehensively and evenly, easily resulting in inconsistent drying degrees on the surface and inside of the leather. This uneven drying will affect the appearance quality of leather products, such as uneven surface color and poor gloss, and at the same time, it will also affect their physical properties and service life. Most leather drying equipment requires manual operation, with low automation, which not only increases the labor intensity but also may lead to risks of inconvenient operation and misoperation. Traditional drying equipment mostly adopts static drying methods and cannot be flexibly adjusted according to the material and thickness of the leather, with low applicability.

[0004] In view of this, this application proposes a drying device for leather processing. Content of the Utility Model

[0005] The purpose of the utility model is to provide a drying device for leather processing to solve the problems raised in the above background art.

[0006] To solve the above technical problems, the technical solution adopted by the utility model is:

[0007] A drying device for leather processing includes a workbench, a drying box body, a plurality of first rollers, and a plurality of second rollers. The workbench is fixedly connected to the drying box body. The second rollers are fixedly connected inside the drying box body. The first rollers are slidably connected inside the drying box body. The first rollers and the second rollers are parallel and arranged alternately. The leather to be dried is inserted in an "S" shape alternately from the first roller above to the rollers below, and finally comes out from the outlet end of the drying box body below. Then, by sliding the first rollers, the travel of the leather inside the drying box body can be increased, enabling the leather to be fully dried.

[0008] Further, it also includes a plurality of positioning components. The positioning components include: two second sliders, two rotary fasteners, and four first limiting support rods. On both sides of the drying box body, there are respectively provided chute 1 which is slidably connected to the second slider. Both ends of the first drum are fixedly connected to the two second sliders respectively. The two rotary fasteners are respectively rotatably connected to the two second sliders. The four first limiting support rods are fixedly connected to the drying box and are respectively arranged on both sides of the two chute 1. The rotary fastener is parallel to the chute 1. Pull the rotary fasteners located on both sides of the drying box body to move them to the other side of the first limiting support rod, and then rotate the rotary fasteners to make them perpendicular to the chute 1, so that the first limiting support rod restricts the rotary fasteners. Finally, even under the action of the leather movement, the first drum no longer moves back. This greatly improves the flexibility of the device.

[0009] Further, it also includes a pressing cylinder component. The pressing cylinder component includes: two supports, a first pressing cylinder, a second pressing cylinder, two first sliders, and two springs. The two supports are respectively fixedly connected to both sides of the workbench. The two supports are respectively provided with chute 2 which is slidably connected to the two first sliders. One end of each of the two springs is fixedly connected to the two first sliders respectively, and the other end is fixedly connected to the two supports respectively. Both ends of the first pressing cylinder are rotatably connected to the two first sliders respectively. Both ends of the second pressing cylinder are rotatably connected to the two supports respectively and are located below the first pressing cylinder. Before the leather enters the drying rod box body, the leather needs to pass through the middle of the first pressing cylinder and the second pressing cylinder for rolling. The first pressing cylinder can move in the chute 2 under the action of the spring according to the leather thickness, improving the applicability of the device.

[0010] Further, the door opening and closing component includes: a lifting door, four second limiting support rods, and two limiting fasteners.

[0026] The following further describes the present utility model in detail with reference to embodiments:

[0027] Embodiment 1: Please refer to Figures 1-7 , this embodiment provides a drying device for leather processing, including a workbench 14, a drying box body 4, a plurality of positioning components, a pressing cylinder component, and may further include two first rollers 12, three second rollers 13, a take-up component, a ventilation component, and a plurality of infrared dryers 16.

[0028] The workbench 14 is fixedly connected to the drying box body 4. The second roller 13 is fixedly connected inside the drying box body 4. The first roller 12 is slidably connected inside the drying box body 4. The first roller 12 and the second roller 13 are parallel and arranged alternately. The leather to be dried is alternately inserted in an "S" shape from the uppermost second roller 13 to the lower rollers, and finally comes out from the outlet end of the lower drying box body 4. Then, by sliding the first roller 12, the travel of the leather inside the drying box body 4 can be increased, enabling the leather to be fully dried. Both the first roller 12 and the second roller 13 are made of stainless steel. Stainless steel has good corrosion resistance, can resist the erosion of chemical substances that may be generated during the drying process, and extends the service life of the equipment. The surface is smooth, not easily adherent to dirt, facilitating daily maintenance and cleaning. It can withstand the high-temperature environment during the drying process and maintain structural stability.

[0029] The positioning assembly includes: two second sliders 20, two rotary fasteners 6, and four first limiting support rods 11. On both sides of the drying box body 4, there are respectively provided with a first chute for sliding connection with the second slider 20. Both ends of the first drum 12 are fixedly connected to the two second sliders 20 respectively. The two rotary fasteners 6 are respectively rotatably connected to the two second sliders 20. The four first limiting support rods 11 are fixedly connected to the drying box body 4 and are respectively arranged on both sides of the two first chutes. First, make the rotary fastener 6 parallel to the first chute, pull the rotary fasteners 6 located on both sides of the drying box body 4, and move them to the other side of the first limiting support rod 11, and then rotate the rotary fastener 6 to make it perpendicular to the first chute, so that the first limiting support rod 11 restricts the rotary fastener 6. Finally, even under the action of the leather movement, the first drum 12 no longer moves back. The positioning assembly greatly improves the flexibility of the device. A layer of lubricant is applied to the contact surface between the second slider 20 and the drying box body 4. The lubricant can form a lubricating film between two or more contact surfaces, thereby reducing their direct contact and friction. This can not only slow down wear and extend the service life of the contact surface.

[0030] The pressing cylinder assembly includes: two supports 18, a first pressing cylinder 7, a second pressing cylinder 10, two first sliders 8, and two springs 9. The two supports 18 are respectively fixedly connected to both sides of the workbench 14. The two supports 18 are respectively provided with a second chute for sliding connection with the two first sliders 8. One ends of the two springs 9 are respectively fixedly connected to the two first sliders 8, and the other ends are respectively fixedly connected to the two supports 18. Both ends of the first pressing cylinder 7 are respectively rotatably connected to the two first sliders 8. Both ends of the second pressing cylinder 10 are respectively rotatably connected to the two supports 18 and are located below the first pressing cylinder 7. Before the leather enters the drying rod box body, the leather needs to pass through the middle of the first pressing cylinder 7 and the second pressing cylinder 10 for rolling. The first pressing cylinder 7 can move in the second chute under the action of the spring 9 according to the leather thickness, greatly improving the applicability of the device. It can level different thickness leathers before drying and further exude the moisture in the leather. The spring 9 is a high-strength spring. The high-strength spring can bear a greater load, can make the pressing effect of the pressing cylinder assembly better. The high-strength spring has better anti-fatigue performance, can maintain stable performance during long-term use, and reduce failures caused by fatigue fracture.

[0031] The winding assembly includes: a winding drum 1 and a motor 2. The winding drum 1 is installed on the workbench 14. The motor 2 is fixedly connected to the winding drum 1. The workbench 14 is provided with a small platform fixedly connected to the bottom of the motor 2. When the leather comes out from the outlet end of the drying box body 4, fix the leather on the winding drum 1 and then start the motor 2 to drive the winding drum 1 to rotate by the motor 2, replacing manual pulling of the leather, improving the automation degree of the device and saving manpower.

[0032] The door opening and closing assembly includes: a lifting door 5, four second limiting support rods 19, and two limiting buckles 15. The lifting door 5 is slidably connected to the drying box body 4. The two limiting buckles 15 are respectively rotatably connected to both sides of the drying box body 4. The four second limiting support rods 19 are divided into two groups and fixedly installed on both sides of the drying box body 4, and are located below the limiting buckles 15. When the leather needs to be alternately inserted in an "S" shape inside the drying box body 4, first manually pull the lifting door 5 upwards, then rotate the limiting buckle 15, and lower the lifting door 5 to facilitate the installation of the leather inside the drying box body 4 before drying. After the leather is alternately inserted in an "S" shape inside the drying box body 4, manually move the lifting door 5 upwards, then rotate the limiting buckle 15. Under the action of the limiting buckle 15 and the first limiting support rod 11, the lifting door 5 is restricted from moving downwards anymore, so that there is only a small section of space for the leather to enter on one side where the leather enters and exits the drying box body 4. Thus, the heat preservation effect of the drying box body 4 is improved. The above-mentioned workbench 14 is provided with a square opening for the up and down movement of the lifting door 5, which allows the lifting door 5 to move up and down through the workbench 14.

[0033] The ventilation assembly includes: a filter screen 3 and a fan 17. The fan 17 is installed on the drying box body 4 and is in communication with the drying box body 4. The filter screen 3 is installed inside the fan 17. The filter screen 3 plays a protective role for the fan 17 to prevent some foreign objects from entering the fan 17. When the drying box body 4 is drying leather, the air humidity inside the box body is high, and the fan 17 can make the air inside the drying box body 4 circulate.

[0034] A plurality of infrared dryers 16 are respectively fixedly installed inside the drying box body 4. The infrared dryers 16 have the characteristics of fast heating speed and uniform heating.

[0035] The working principle of the drying device for leather processing is described in detail below: When the leather needs to be dried, first pass one end of the leather through between the first pressing cylinder 7 and the second pressing cylinder 10, so that the leather is flattened and the moisture in it is squeezed out. The first pressing cylinder 7 can move according to the thickness of the leather under the action of the spring 9, improving the applicability of the device. When the leather needs to enter the drying box 4 for "S"-shaped alternating insertion, first manually pull the lifting door 5 upwards, and then rotate the limit buckle 15 to lower the lifting door 5, facilitating the installation of the leather in the drying box 4 before drying. After the leather finishes "S"-shaped alternating insertion in the drying box 4 and comes out from the outlet end of the drying box 4, manually move the lifting door 5 upwards, and then rotate the limit buckle 15. Under the action of the limit buckle 15 and the first limit support rod 11, the lifting door 5 is restricted from moving downwards anymore, so that there is only a small section of space for the leather to enter on one side where the leather enters and exits the drying box 4, improving the heat preservation effect of the drying box 4. First, make the rotating buckle 6 parallel to the first chute, pull the rotating buckles 6 located on both sides of the drying box 4 to move them to the other side of the first limit support rod 11, and then rotate the rotating buckle 6 to make it perpendicular to the first chute, so that the first limit support rod 11 restricts the rotating buckle 6. Finally, even under the action of the movement of the leather, the first roller 12 no longer moves back. The positioning component greatly improves the flexibility of the device, enabling the leather to have a longer travel in the drying box 4 and be fully dried. After starting the infrared dryer 16 and the fan 17, fix the leather coming out from the outlet end of the drying box 4 to the take-up reel 1 and then start the motor 2, eliminating the need for manual pulling of the leather, greatly saving manpower and improving the automation degree of the device. Generally speaking, the drying device for leather processing in this embodiment has the characteristics of simple operation, high drying efficiency, strong applicability, high automation degree, and flexibility.

[0036] The above generally describes the present invention in detail, but based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the technical field. Therefore, modifications or improvements made without departing from the spirit of the present invention are within the protection scope of the present invention.
