[0027] The following is combined with Figure 1-Figure 3 This application is described in further detail.

[0028] The embodiment of the present application discloses a leather parts drying device 100 .

[0029] Reference Figure 1-Figure 3 According to the embodiment of the present application, the leather parts drying device 100 comprises: an oven 1 and a hot air assembly 2. A drying space 11 is defined in the oven 1. A positioning member 12 is provided in the oven 1. The leather parts are suitable for being placed on the top wall of the positioning member 12. Along the height direction of the oven 1, the height direction of the oven 1 can refer to Figure 1 In the up and down directions, the leather parts are placed on the upper end wall of the positioning member 12. It should be noted that the plastic parts in the leather parts are abutted against the upper end wall of the positioning member 12, and the positioning member 12 is positioned and matched with the leather parts. Specifically, the positioning member 12 is positioned and matched with the plastic parts in the leather parts, thereby preventing the leather parts from deviating from the preset position, preventing the leather parts drying equipment 100 from being unable to dry the glue in the leather parts, and thereby improving the working reliability of the leather parts drying equipment 100.

[0030] Furthermore, the upper end wall of the positioning piece 12 may be provided with a contoured positioning portion, which contours according to the shape of the plastic part in the leather part. The plastic part in the leather part is positioned and matched with the contoured positioning portion so that the plastic part in the leather part can fully fit with the positioning piece 12, thereby further improving the positioning and matching effect of the leather part and the positioning piece 12.

[0031] The bottom wall of the positioning member 12 is provided with an avoidance groove 121, and an ultrasonic emitting member 122 is provided in the avoidance groove 121. The ultrasonic emitting member 122 is suitable for being opposite to the leather part, and the ultrasonic emitting member 122 is used to emit ultrasonic waves to the leather part to remove moisture in the glue of the leather part. The hot air component 2 is connected to the drying space 11, and the hot air component 2 is used to blow hot air to the drying space 11 to dry the glue of the leather part.

[0032] Specifically, after the leather part is placed on the positioning part 12, the ultrasonic emitting part 122 is opposite to the leather part, and the ultrasonic emitting part 122 emits ultrasonic waves to the leather part. The ultrasonic waves remove moisture in the glue of the leather part through the cavitation effect, and in the process of the ultrasonic emitting part 122 emitting ultrasonic waves to the leather part, the hot air component 2 blows hot air into the drying space 11 to dry the glue of the leather part.

[0033] It should be noted that ultrasound can generate instantaneous high temperature and high pressure in multiple local areas of the glue through the cavitation effect to evaporate the moisture in multiple local areas of the glue, and ultrasound can also generate high-frequency vibrations in the glue through the cavitation effect. The high-frequency vibrations cause the moisture at the junction of the glue and the external environment to leave the glue, thereby further improving the efficiency of removing moisture from the glue.

[0034] In some specific embodiments, the ultrasonic emitting element 122 may be a piezoelectric ultrasonic emitter or the like.

[0035] Thus, ultrasonic waves are emitted to the leather parts by the ultrasonic emitting element 122, and the ultrasonic waves remove the moisture in the glue of the leather parts through the cavitation effect, and the hot air component 2 blows hot air into the drying space 11. Compared with the prior art, in the process of hot air drying the glue, the moisture in the glue of the leather parts is further removed by ultrasonic waves, so that the drying time of the leather parts can be shortened, and the production efficiency of the leather parts can be improved.

[0036] Reference Figure 2 and Figure 3 In some embodiments of the present application, there are multiple ultrasonic emitting elements 122, and the multiple ultrasonic emitting elements 122 are sequentially arranged along the radial direction of the oven 1. Specifically, the multiple ultrasonic emitting elements 122 are sequentially arranged along the first direction of the oven 1, and the multiple ultrasonic emitting elements 122 are sequentially arranged along the second direction of the oven 1. That is, or, the multiple ultrasonic emitting elements 122 are arranged in an array, and the first direction of the oven 1 can be up to Figure 1 The second direction of the oven 1 may refer to the front-to-back direction. Figure 1 The left and right direction in .

[0037] By providing a plurality of ultrasonic emitting elements 122, the plurality of ultrasonic emitting elements 122 can jointly emit ultrasonic waves to the leather parts, thereby improving the efficiency of removing moisture from the glue of the leather parts, further shortening the drying time of the leather parts, and improving the production efficiency of the leather parts.

[0038] Reference Figure 2 and Figure 3 In some embodiments of the present application, the leather parts drying equipment 100 may further include: a controller, a thickness detection member 13 may be provided in the oven 1, the thickness detection member 13 is suitable for being opposite to the leather parts, the thickness detection member 13 is used to detect the glue thickness of multiple preset areas of the leather parts, the multiple preset areas are spaced apart along the radial direction of the leather parts, and the multiple preset areas are arranged in a one-to-one correspondence with multiple ultrasonic emitting members 122, the ultrasonic emitting members 122 and the thickness detection member 13 are both communicatively connected to the controller, and the controller is used to control the emission power of the corresponding ultrasonic emitting member 122 according to the detection signal of the thickness detection member 13.

[0039] Specifically, after the leather parts are placed on the positioning parts 12, the thickness detection part 13 detects the glue thickness of multiple preset areas. When the glue thickness of the preset area is greater than the preset glue thickness value, the thickness detection part 13 generates a first detection signal. The controller increases the transmission power of the ultrasonic transmitting part 122 corresponding to the preset area according to the first detection signal of the thickness detection part 13, thereby shortening the time for removing moisture in the area where the glue thickness of the leather parts is thicker, and further shortening the drying time of the leather parts.

[0040] Moreover, when the glue thickness in the preset area is less than the preset glue thickness value, the thickness detection element 13 generates a second detection signal, and the controller reduces the transmission power of the ultrasonic transmitter 122 corresponding to the preset area according to the second detection signal of the thickness detection element 13, thereby avoiding as much as possible the damage of the leather in the leather parts caused by the transmission power of the ultrasonic transmitter 122 being too high, thereby improving the product quality of the leather parts.

[0041] In some specific embodiments, the preset glue thickness value may be 2 mm.

[0042] In some specific embodiments, the thickness detection element 13 may be an ultrasonic thickness sensor. The thickness detection element 13 transmits ultrasonic waves to the leather parts. The thickness detection element 13 determines the glue thickness by calculating the difference between the ultrasonic wave emission time and the ultrasonic wave return time.

[0043] Furthermore, the thickness detection component 13 is also used to detect whether multiple preset areas of the leather parts are coated with glue. When the preset areas are not coated with glue, the thickness detection component 13 generates a stop signal, and the controller controls the ultrasonic emitting component 122 corresponding to the preset areas to stop emitting ultrasonic waves according to the stop signal. When the preset areas are coated with glue, the thickness detection component 13 generates a start signal, and the controller controls the ultrasonic emitting component 122 corresponding to the preset areas to emit ultrasonic waves according to the start signal. Such a setting can reduce the energy consumption of the leather parts drying equipment 100.

[0044] Reference Figure 2 and Figure 3 In some embodiments of the present application, there are multiple positioning members 12 and multiple ultrasonic emitting members 122, and the multiple positioning members 12 and multiple ultrasonic emitting members 122 are spaced apart along the radial direction of the oven 1, and the multiple positioning members 12 and multiple ultrasonic emitting members 122 are arranged in a one-to-one correspondence.

[0045] Specifically, multiple positioning members 12 and multiple ultrasonic emitting members 122 are arranged in sequence along the first direction of the oven 1, and multiple positioning members 12 and multiple ultrasonic emitting members 122 are arranged in sequence along the second direction of the oven 1, that is, multiple positioning members 12 and multiple ultrasonic emitting members 122 are arranged in an array, and multiple ultrasonic emitting members 122 can be arranged in one avoidance groove 121.

[0046] By setting up multiple positioning members 12 and multiple ultrasonic emitting members 122, each of the multiple positioning members 12 can be placed with leather parts, and the multiple ultrasonic emitting members 122 emit ultrasonic waves to the corresponding positioning members 12 to remove moisture from the glue of the corresponding leather parts. The leather parts drying equipment 100 can dry multiple leather parts at the same time, thereby improving the working efficiency of the leather parts drying equipment 100, and further improving the user experience of the leather parts drying equipment 100.

[0047] Reference Figure 1 and Figure 2 In some embodiments of the present application, the oven 1 includes a support seat 14 and a cover body 15, the cover body 15 is covered on the top wall of the support seat 14, and a drying space 11 is defined between the cover body 15 and the support seat 14, and the positioning member 12 is arranged on the top wall of the support seat 14. Specifically, along the height direction of the oven 1, the cover body 15 is covered on the upper end wall of the support seat 14, and the positioning member 12 is arranged on the upper end wall of the support seat 14.

[0048] Along the first direction of the oven 1, one end of the cover body 15 is pivotally connected to the support seat 14, and the outer peripheral wall of the support seat 14 is provided with a driving member 141, and the driving member 141 is connected and cooperated with the other end of the cover body 15. Specifically, the rear end of the cover body 15 is pivotally connected to the rear end of the support seat 14, and the outer peripheral wall of the front end of the support seat 14 is provided with a driving member 141, and the output end of the driving member 141 is connected and cooperated with the front end of the cover body 15.

[0049] Furthermore, the driving member 141 is used to drive the cover 15 to rotate around the pivot axis between the cover 15 and the support seat 14. The cover 15 is used to open or close the oven 1. Specifically, the driving member 141 drives the cover 15 to rotate around the pivot axis between the cover 15 and the support seat 14 in a direction away from the support seat 14 to open the oven 1, and the driving member 141 drives the cover 15 to rotate around the pivot axis between the cover 15 and the support seat 14 in a direction close to the support seat 14 to close the oven 1, thereby achieving the technical effect of driving the cover 15 to rotate to open or close the oven 1 by the driving member 141. Moreover, compared with the operator driving the cover 15 to rotate around the pivot axis between the cover 15 and the support seat 14 by hand, such a setting can reduce the worker's work intensity, thereby improving the user experience of the leather parts drying device 100.

[0050] In some specific embodiments, the driving member 141 may be an electric strut, but the present application is not limited thereto, and the driving member 141 may also be a cylinder or the like.

[0051] Furthermore, the thickness detection member 13 is disposed on the upper end wall of the cover body 15 .

[0052] Reference Figure 2 and Figure 3 In some embodiments of the present application, a pressure-resisting film 151 suitable for elastic deformation is provided in the cover body 15, and the pressure-resisting film 151 is located in the drying space 11. The pressure-resisting film 151 is located on the side of the leather part away from the positioning member 12, that is, along the height direction of the oven 1, the pressure-resisting film 151 is located above the positioning member 12, and the pressure-resisting film 151 is spaced apart from the upper end wall of the support seat 14, and the pressure-resisting film 151 is suitable for being opposite to and press-fitting with the leather part, and the pressure-resisting film 151 is used to press the leather part onto the positioning member 12.

[0053] Specifically, after the part is placed on the positioning piece 12, the cover body 15 rotates around the pivot axis between the cover body 15 and the support seat 14 toward the support seat 14, and the pressing film 151 stops against the upper end wall of the leather part. When the cover body 15 stops against the support seat 14, the pressing film 151 presses the leather part on the positioning piece 12, and the pressing film 151 undergoes elastic deformation. The area of ​​the pressing film 151 opposite to the leather part protrudes in the direction away from the support seat 14. The leather part is pressed on the positioning piece 12 by the pressing film 151, thereby preventing the leather part from deviating from the preset position during the process of drying the leather part by the leather part drying equipment 100, resulting in the ultrasonic emitting element 122 being unable to emit ultrasonic waves to the leather part, thereby improving the working reliability of the leather part drying equipment 100.

[0054] In some specific embodiments, the pressing film 151 may be a transparent silicone film, but the present application is not limited thereto. The pressing film 151 may also be a polyurethane film or the like.

[0055] Furthermore, a transparent window is provided on the outer peripheral wall of the cover body 15 , and the transparent window is arranged opposite to the positioning piece 12 , and the operator can observe through the transparent window whether the leather part is in the preset position and whether the pressing film 151 presses the leather part onto the positioning piece 12 .

[0056] Reference Figure 2 In some embodiments of the present application, a top wall of the support seat 14 is provided with a plurality of vacuum holes 142, and the plurality of vacuum holes 142 are spaced apart along the radial direction of the oven 1. An exhaust channel 143 is defined in the support seat 14, and the plurality of vacuum holes 142 are connected to the drying space 11 and the exhaust channel 143. Specifically, along the height direction of the oven 1, the plurality of vacuum holes 142 are all located on the upper end wall of the support seat 14, the drying space 11 is located above the vacuum holes 142, and the exhaust channel 143 is located below the vacuum holes 142.

[0057] In addition, the exhaust channel 143 is connected to a vacuum pump, which is used to suck the gas in the drying space 11 to form a negative pressure in the drying space 11. Specifically, after the pressure membrane 151 presses the leather parts onto the positioning member 12, the vacuum pump starts working, and the vacuum pump sucks the gas in the drying space 11 through the exhaust channel 143 and a plurality of vacuum holes 142. That is, the vacuum pump sucks the gas between the pressure membrane 151 and the upper end wall of the support seat 14 to form a negative pressure in the drying space 11.

[0058] Under the action of negative pressure, the pressure film 151 fits tightly against the leather parts, so that the pressure film 151 can press the leather parts onto the positioning member 12 as much as possible, thereby avoiding a gap between the pressure film 151 and the leather parts, which would cause the leather parts to shake under the blowing of hot air, and avoiding the leather parts from deviating from the preset position, resulting in the ultrasonic transmitter 122 being unable to transmit ultrasonic waves to the leather parts, thereby improving the working reliability of the leather parts drying equipment 100.

[0059] Reference Figure 2 and Figure 3 In some embodiments of the present application, a positioning groove 123 is provided on the top wall of the positioning member 12, and the leather part is placed in the positioning groove 123 and positioned with the positioning groove 123, and the leather part protrudes from the top wall of the positioning member 12. Specifically, along the height direction of the oven 1, a positioning groove 123 is provided on the upper end wall of the positioning member 12, and the upper end of the leather part protrudes from the upper end wall of the positioning member 12, and a connecting hole 124 is provided on the inner peripheral wall of the positioning groove 123, and the connecting hole 124 is constructed as a through hole, and the connecting hole 124 is suitable for connecting with a vacuum pump, and the vacuum pump is used to suck the gas between the pressure film 151 and the leather part to form a negative pressure between the pressure film 151 and the leather part.

[0060] Furthermore, the communication hole 124 is connected to the drying space 11 , and the vacuum pump sucks the gas between the pressure film 151 and the leather parts through the exhaust channel 143 , the vacuum hole 142 and the drying space 11 in sequence.

[0061] When the plastic part in the leather part is provided with a molding groove, and the area of ​​the leather in the leather part corresponding to the molding groove needs to extend into the molding groove, by forming a negative pressure between the pressure-resisting film 151 and the leather part, the pressure-resisting film 151 can press the area of ​​the leather corresponding to the molding groove into the molding groove, thereby achieving the technical effect of manufacturing the leather part in a preset shape.

[0062] Reference Figure 2 In some embodiments of the present application, a sealing ring 152 is provided between the support seat 14 and the cover body 15. By providing the sealing ring 152 between the support seat 14 and the cover body 15, the sealing ring 152 is used to seal the connection between the support seat 14 and the cover body 15, which can prevent the hot air in the oven 1 from flowing out of the oven 1 from between the support seat 14 and the cover body 15, and can prevent the temperature in the oven 1 from failing to reach the preset temperature, thereby preventing the glue in the leather assembly from failing to be dried, and further improving the working reliability of the leather parts drying device 100.

[0065] Specifically, the air inlet end 211 of the fan 21 draws the gas in the drying space 11, and then the air outlet end 212 of the fan 21 delivers the gas into the drying space 11, and the heating element 22 heats the gas delivered by the air outlet end 212 of the fan 21, thereby achieving the technical effect of blowing hot air into the drying space 11.
