[0002] When producing leather products, such as the headrests, backrests, seat cushions or armrests of hard leather chairs, edge oiling treatment needs to be carried out on the leather products. Edge oiling treatment means applying emulsified oil to the edge cuts of the leather and sending it into a drying box through a conveyor belt for drying. The previous drying boxes used resistance wires to heat the air and used fans to blow the hot air to the surface of the leather products. However, such a heating method not only consumes a large amount of energy, but also has a high temperature near the air outlet and a low temperature far from the air outlet, resulting in inconsistent drying degrees of the leather products placed at different positions; therefore, drying boxes using infrared lamps for heating have been developed and manufactured.

[0003] However, it is found in use that the drying boxes using infrared lamps for heating still have some deficiencies; for example, the heating temperature of the infrared lamps decreases with the increase of the distance, and the infrared lamps are installed on the side walls of the drying box, which results in that for the same leather product, the parts close to the side walls of the drying box receive more heat, and the parts located in the center receive less heat, and there is still an uneven problem.

[0023] Next, refer to Figures 1 to 5Describe a leather product drying device and a drying method according to an embodiment of the present invention.

[0024] The leather product drying device according to the embodiment of the first aspect of the present invention includes a conveyor belt 900, a fixture assembly, and a drying box 100.

[0025] The conveyor belt 900 extends horizontally, and a horizontally extending drying channel is provided on the upper side of the conveyor belt 900. Among them, since a small part of the surface of the emulsified oil used for edge coating will form small bubbles when the drying temperature exceeds 85°C, and most of the surface of the emulsified oil will form large bubbles when the drying temperature exceeds 90°C, resulting in the product not meeting the quality requirements. Therefore, the actual drying temperature is lower than 85°C. Thus, the belt body of the conveyor belt 900 can be made of a heat-resistant material belt body such as canvas.

[0026] The fixture assembly includes a plurality of supporting fixtures 020. Refer to Figure 1 , a plurality of supporting fixtures 020 are arranged on the conveyor belt 900 in sequence along the horizontal direction. The supporting fixture 020 includes a base 200 and a tray 210. The base 200 is located at the bottom of the supporting fixture 020, and the base 200 is used to be placed on the upper side of the conveyor belt; among them, magnets can be provided on the base 200, and the belt body of the conveyor belt 900 can be made of a wire rope core belt body, an iron mesh belt body, or a belt body made of other ferromagnetic substances, so that the base 200 can be closely attached to the conveyor belt 900 under the action of magnetic force, so that there is a large frictional force between the base 200 and the conveyor belt 900, and then the supporting fixture 020 can be stably placed on the conveyor belt, not easy to slip, and convenient for taking and placing; the tray 210 is used to place leather products. When in use, the leather products can be placed on the upper side of the tray 210. The tray 210 is rotatably arranged on the base 200 through a vertically arranged first rotating shaft 271. The first rotating shaft 271 is arranged at the bottom of the tray 210, so that the leather products placed on the upper side of the tray 210 can rotate together with the tray 210.

[0027] The base 200 is provided with a first transmission member 220. The first transmission member 220 can be a wheel-shaped member such as a pulley, a gear, a sprocket, or a worm. The first transmission member 220 is rotatably arranged on the base 200, and the first transmission member 220 is linked to the tray 210, so that the rotation action of the first transmission member 220 is linked to the rotation action of the tray 210. Refer to Figure 2, the set tray 210 can be fixedly connected to the top end of the first rotating shaft 271, the first transmission member 220 is fixedly arranged in the middle of the first rotating shaft 271, and the bottom end of the first rotating shaft 271 is rotatably arranged on the base 200, so that the first rotating shaft 271, the tray 210, and the first transmission member 220 can rotate together; the path along which the first transmission member 220 moves along the conveyor belt 900 is called the first path, and the first path extends horizontally; when the conveyor belt 900 drives the supporting jig 020 to move horizontally, the first transmission member 220 will also move horizontally relative to the drying box 100, and the path along which the first transmission member moves horizontally relative to the drying box 100 is the first path.

[0028] The drying box 100 is sleeved on the outside of the drying channel. The drying box 100 has a front side wall, a rear side wall, and a top wall. The conveyor belt 900 is the bottom wall of the drying box 100. The drying box 100 is provided with two box doors, which are respectively called the feeding box door and the discharging box door. The feeding box door is arranged at the left end of the drying box 100 and is used to cover the left end of the drying channel. The discharging box door is arranged at the right end of the drying box 100 and is used to cover the right end of the drying channel; the conveyor belt 900 is provided with a feeding section 910 protruding leftward from the drying box 100 and a discharging section 920 protruding rightward from the drying box 100. When in use, the leather products to be dried can be placed on the feeding section 910, and the dried leather products can be taken out from the discharging section 920.

[0029] The drying box 100 is provided with a second transmission member 130 and a driving device 120 for driving the second transmission member 130. The second transmission member 130 is arranged inside the drying box 100. The second transmission member 130 is in the shape of a strip extending horizontally. The second transmission member 130 is arranged beside the first path. The second transmission member 130 can be a synchronous belt, a toothed belt, a chain, a worm, or other strip-shaped components. The first transmission member 220 is in transmission connection with the second transmission member 130; the driving device 120 can be a motor. The motor is arranged outside the drying box 100. The driving shaft of the motor penetrates the side wall of the drying box 100, extends into the drying box 100, and is in transmission connection with the second transmission member 130.

[0030] When in use, the leather products can be placed on the tray 210 of the supporting jig 020, and the supporting jig 020 can be placed on the conveyor belt 900. The conveyor belt 900 can send the leather products and the supporting jig 020 into the drying box 100 to dry the leather products, and the conveyor belt 900 can also send out the dried leather products and the supporting jig 020 together; when drying, the driving device 120 can be started, and under the transmission of the first transmission member 220 and the second transmission member 130, the tray 210 can rotate and then drive the leather products arranged thereon to rotate, avoiding the problem that the parts of the leather products close to the side walls of the drying box 100 receive more heat and the parts located in the center receive less heat, which is conducive to uniform drying; wherein, by arranging the second transmission member 130 on the side of the first path, the second transmission member 130 will not hinder the lateral movement of the supporting jig 020.

[0031] In some embodiments of the present invention, the first transmission member 220 is a worm wheel, the second transmission member 130 is a worm, and the worm wheels of multiple supporting fixtures 020 are all connected to the worm. When the worm does not rotate, the meshing between the worm wheel and the worm is equivalent to the meshing between the gear and the rack, that is, the worm wheel can move laterally while maintaining meshing with the worm, so that the worm can drive the worm wheel when the supporting fixture 020 is transported to any position in the drying channel, and the worm can drive the worm wheels of multiple supporting fixtures 020 at the same time; wherein, the side wall of the drying box 100 is provided with two first support arms, and the two ends of the worm are respectively rotatably arranged on the two first support arms, and one end of the worm is connected to the driving shaft of the motor through a gear transmission.

[0032] In some embodiments of the present invention, reference Figure 4 The drying box 100 is provided with a horizontally extending guide rail 140, which is arranged at the rear side of the supporting fixture 020, the axial direction of the worm wheel is vertical, the worm wheel is arranged at the front side of the worm wheel, the supporting fixture 020 is arranged between the guide rail 140 and the worm, and the base 200 is provided with an abutment 201, which slides against the guide rail 140. In this way, the guide rail 140 can apply a force toward the worm to the supporting fixture 020, so that the worm wheel can maintain engagement with the worm; wherein the abutment 201 is a roller with a vertical axial direction, the number of rollers can be two, and the two rollers are arranged at intervals on the left and right, and the left end of the guide rail 140 is provided with a guide section 141 extending to the left rear, so that when the supporting fixture 020 moves from left to right into the drying box 100, it can move smoothly between the guide rail 140 and the worm.

[0033] In some embodiments of the present invention, a clamping frame 240 is provided on the upper side of the base 200, and the clamping frame 240 is provided with a first clamping arm 231 and a second clamping arm 211, and the first clamping arm 231 and the second clamping arm 211 are arranged at intervals up and down, one end of the first clamping arm 231 is hinged to the clamping frame 240, and the hinge shaft at the hinge is arranged horizontally, and the other end of the first clamping arm 231 is rotatably provided with a clamping member 230, and the rotating shaft rotatably connected between the first clamping arm 231 and the clamping member 230 is arranged vertically. The tray 210 is arranged on the second clamping arm 211, the clamping member 230 and the tray 210 are both arranged between the first clamping arm 231 and the second clamping arm 211, and a clamping space for clamping leather products is arranged between the tray 210 and the clamping member 230; the first clamping arm 231 is connected with an elastic member 232 for driving the first clamping arm 231 to move closer to the second clamping arm 211, and the elastic member 232 can be a tension spring, and the two ends of the tension spring are respectively connected to the first clamping arm 231 and the second clamping arm 211. When in use, the leather product can be clamped between the tray 210 and the clamping member 230, so that the leather product is not easy to fall from the supporting fixture 020; by setting the clamping member 230 to be rotatably connected to the first clamping arm 231, when the tray 210 drives the leather product to rotate, the clamping member 230 can rotate accordingly, avoiding the problem of friction between the clamping member 230 and the leather product causing damage to the leather product.

[0034] It can be understood that the locations where leather products such as headrests, backrests, seat cushions or armrests of hard leather chairs need to be treated with oil edges are usually located on the periphery of the leather products, that is, the tray 210 and the clamping member 230 will not cover the locations where oil edges need to be treated.

[0035] In some embodiments of the present invention, the side walls and the top wall of the drying box 100 are provided with infrared lamps 110, which heat the leather products at multiple angles, which is conducive to making the leather products more evenly dried. A support frame 290 is provided on the upper side of the base 200, and the clamping frame 240 is rotatably arranged on the support frame 290 through the second rotating shaft 272 extending forward and backward. The first transmission member 220 is linked to the support frame 290. Figure 2 In this way, when drying, the first transmission member 220 can drive the clamping frame 240 to rotate with the second rotating shaft 272 as the axis, so that the leather product can be turned upside down, avoiding the problem that only one side of the leather product can be heated by the infrared lamp 110 on the top, which is conducive to making the leather product more evenly dried. Among them, the second rotating shaft 272 is set at the front side or the rear side of the clamping space, and the second rotating shaft 272 does not occupy the position on the left side or the right side of the clamping space, so that the placement positions of two adjacent leather products can be closer, that is, the drying channel can accommodate more leather products at the same time, and more leather products can be dried in one drying operation.

[0036] In some embodiments of the present invention, reference Figure 5 and Figure 6, the clamping frame 240 is fixedly connected to the second rotating shaft 272. The support frame 290 is rotatably provided with a first gear 281. The first gear 281 is linked to the first transmission member 220. The second rotating shaft 272 is fixedly provided with a second gear 282. The first gear 281 meshes with the second gear 282. The support frame 290 includes a first pipe portion 291 extending vertically and a second pipe portion 292 extending front and rear. The bottom of the first pipe portion 291 is fixedly connected to the base 200. A first transmission shaft 261 is vertically arranged in the first pipe portion 291. The first transmission shaft 261 is rotatably connected to the base 200 and the first pipe portion 291. The top end of the first transmission shaft 261 protrudes from the top of the first pipe portion 291. The first gear 281 is fixedly arranged at the top end of the first transmission shaft 261. The first transmission member 220 is fixedly arranged on the lower side of the first transmission shaft 261. The second pipe portion 292 is arranged above the first gear 281. Connecting bridges are provided on the front side and the rear side of the second pipe portion 292 and cross over the first gear 281 downward. The connecting bridges are fixedly connected between the first pipe portion 291 and the second pipe portion 292. The second rotating shaft 272 is rotatably arranged in the second pipe portion 292. The rear end of the second rotating shaft 272 protrudes from the second pipe portion 292 and is fixedly connected to the clamping frame 240. The front end of the second rotating shaft 272 protrudes from the second pipe portion 292 and is fixedly connected to the first gear 281. Both the first gear 281 and the second gear 282 are bevel gears. In this way, when the first transmission member 220 rotates, the first gear 281 rotates, then the second gear 282 rotates, and then the second rotating shaft 272 rotates, that is, the linkage between the clamping frame 240 and the first transmission member 220 is realized, and the structure is simple and compact.

[0037] In some embodiments of the present invention, the support frame 290 is fixedly provided with a third gear 283. The third gear 283 is arranged at the rear end of the second pipe portion 292. The third gear 283 and the second rotating shaft 272 are coaxial. The clamping frame 240 is rotatably provided with a fourth gear 284. Both the third gear 283 and the fourth gear 284 are spur gears.

The fifth gear 285 meshes with a sixth gear 286. Both the fifth gear 285 and the sixth gear 286 are bevel gears. The tray 210 and the sixth gear 286 are respectively fixedly arranged at both ends of the first rotating shaft 271. In this way, when the clamping frame 240 rotates around the second rotating shaft 272, the fourth gear 284 rolls along the outer circumference of the third gear 283, then the fourth gear 284 rotates around the second transmission shaft 262, then the fifth gear 285 rotates, then the sixth gear 286 rotates, and then the first rotating shaft 271 rotates, that is, the linkage connection between the first transmission member 220 and the tray 210 is realized, and the structure is simple and compact.

[0038] The present invention also has the following beneficial effects: First, compared with conventional drying equipment that cannot rotate leather products, the present invention only needs to add an actuator (i.e., a motor) to achieve the rotation and flipping of multiple leather products. The structure is simple, without the need to set up complex devices such as industrial manipulators, and there will be no bumps on the leather products during the rotation and flipping processes. Second, the supporting fixture and the conveyor belt can be separated from each other, and the supporting fixture and the second transmission member can also be separated from each other. During use, the distance between the supporting fixtures can be adjusted as needed. Third, if it is necessary to obtain the present invention based on a drying equipment with a conventional structure, the only modification required for the equipment is to add a motor, a worm, and a guide rail. The use of the supporting fixture does not require modification of the existing equipment, that is, the present invention can be modified from the existing drying equipment through simple modification, which is convenient for popularization and application.

[0039] In some embodiments of the present invention, the drying box 100 is provided with two box doors, which are respectively arranged at both ends of the drying channel; referring to Figure 3 , the conveyor belt 900 has a feeding section 910 located outside the drying box 100, and the length of the feeding section 910 is the same as the length of the drying channel. The drying box 100 is arranged on the downstream side of the feeding section 910. By setting two box doors, the two box doors can be closed during drying for heat preservation; by setting the feeding section 910, during use, when the first batch of leather products is being dried in the drying box 100, the second batch of leather products can be pre-placed on the feeding section 910, and then after the first batch of leather products is dried, the second batch of leather products can be sent into the drying box 100 together, which is beneficial to saving the feeding time and improving the production efficiency.

[0040] The drying method according to the second aspect embodiment of the present invention uses the above-mentioned leather product drying equipment to dry leather products, and the drying method includes the following steps: Step S001, start multiple infrared lamps 110; Step S100, place multiple leather products one by one on the trays 210 of multiple supporting fixtures 020; Step S200, place multiple supporting fixtures 020 on the feeding section 910 in sequence along the transverse direction, so that the upper side of the feeding section 910 is covered with leather products; in this way, the space in the drying channel can be fully utilized, and the number of leather products dried each time is relatively large.

[0041] Step S300, open the box door, start the conveyor belt 900 to send multiple leather products into the drying box 100, and then close the box door.

[0042] Step S400, start the driving device 120 to make multiple leather products rotate.

[0043] By using the above leather product drying equipment, when drying, the leather product can rotate, avoiding the problem that the part of the leather product close to the side wall of the drying box 100 receives more heat and the part at the center receives less heat, which is beneficial to making the drying uniform.

[0044] In some embodiments of the present invention, in step S200, the step of sequentially placing a plurality of supporting jigs 020 along the transverse direction in the feeding channel includes: Step S210, adjusting the distance between two corresponding supporting jigs 020 according to the rotation ranges of two adjacent leather products, so as to leave a gap between the two rotation ranges and the width of the gap is not greater than a preset value.

[0045] It can be understood that the external dimensions of leather products such as the headrest, backrest, seat cushion or armrest of a hard leather chair are inconsistent; in this embodiment, by providing the supporting jig 020, the supporting jig 020 can be placed at any position on the conveyor belt 900, and then the distance between adjacent supporting jigs 020 can be adjusted during use, so that two adjacent leather products are as close as possible without interfering with each other, thereby saving space, enabling a larger number of leather products to be dried in each batch, and being beneficial to improving production efficiency.

[0046] The above has specifically described the preferred embodiments of the present invention, but the present invention is not limited to the embodiments. Those skilled in the art can also make various equivalent variations or substitutions without departing from the spirit of the present invention, and these equivalent variations or substitutions are all included in the scope defined by the claims of this application.
