DETAILED DESCRIPTION

[0044] The following will be combined with the accompanying drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, in the following description, specific details such as specific system structures and technologies are proposed for the purpose of explanation rather than limitation, so as to thoroughly understand the embodiments of the utility model. However, it should be clear to those skilled in the art that the utility model can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from hindering the description of the utility model.

[0045] The utility model provides a leather stretch board drying device, according to the attached manual Figure 1 -Attached Figure 5It can be seen that a leather stretch board drying device includes: a box body 10, a drying box 11, a windshield 12 and a linkage mechanism 30. Under the action of the driving component 20, the drying box 11 can be lifted and lowered at the top of the box body 10, and a plurality of air outlets are arranged at intervals at the bottom of the drying box 11. A fan 15 and a heating tube 16 are arranged in sequence from top to bottom in the drying box 11 above the air outlets; a plurality of windshields 12 correspond to and fit with the plurality of air outlets respectively, and the windshields 12 swing under the action of the linkage mechanism 30; a plurality of fixing frames 13 are arranged vertically and are arranged at intervals along the length direction of the bottom of the box body 10, and a stretch board is arranged in the fixing frame 13. 14; The linkage mechanism 30 includes: a linkage rod 31 is horizontally arranged below the bottom of the drying box 11, and a plurality of connecting shafts 32 are vertically arranged on the linkage rod 31. The plurality of connecting shafts 32 are respectively connected to a plurality of windshields 12 through a plurality of mutually parallel first connecting rods 33. After the first end of each windshield 12 is connected to and penetrates the rotating shaft of the drying box 11, it is connected to the upper end of the corresponding first connecting rod 33. The lower end of the first connecting rod 33 is connected to the rotating shaft of the corresponding connecting shaft 32, and the linkage rod 31 swings back and forth under the action of the swinging member 34. A handle 18 is arranged at one end of the fixed frame 13 close to the sealing door 17. Two casters 19 are respectively arranged at the two ends of the bottom of the fixed frame 13. A sealing door 17 is also arranged on the box body 10 corresponding to the fixed frame 13.

[0046] When drying, open the sealed door 17, pull the handle 18 outward, pull the fixed frame 13 out of the box body 10, and fix the leather to be dried on the stretching board 14. After completion, push the fixed frame 13 inward. The lower end of the fixed frame 13 is equipped with casters 19 for easy movement. Close the sealed door 17, and the heating tube 16 is powered on for heating. The fan 15 arranged above it blows the hot air downward. When leather of different humidity or different thickness is fixed on the stretching board 14, the driving component 20 can be operated according to actual conditions to adjust the distance between the air outlet of the drying box 11 and the stretching board 14. The driving component 20 is operated to drive the drying box 11 to rise and fall, and then adjust the distance between the drying box 11 and the stretching board 14. When the distance between the drying box 11 and the stretching board 14 changes, the drying temperature will also change accordingly. The inclination angle between the windshield 12 and the air outlet is adjusted by operating the linkage mechanism 30, so that the hot air evenly covers all parts of the leather, thereby improving the leather recovery rate of the leather. Multiple fixing frames 13 can be placed in the box 10 to heat and dry multiple leathers at the same time, which improves the practicality of the device. The swinging member 34 drives the linkage rod 31 to swing, and the linkage rod 31 drives the windshield plate 12 to swing through the connecting shaft 32 and the first connecting rod 33 thereon, so that the blowing angle is adjusted. Compared with the prior art, the utility model has high leather drying efficiency, uniform drying, and high leather yield.

[0047] In this embodiment, according to the specification Figure 2 -Attached Figure 3It can be seen that the swing component 34 includes a first motor 342 arranged in the drying box 11, a second connecting rod 341 is arranged at the output end of the first motor 342, and a connecting column 343 arranged at the free end of the second connecting rod 341 is slidably connected to and penetrates a guide groove 344 arranged at one end of the linkage rod 31.

[0048] When the blowing angle needs to be changed, the first motor 342 is turned on, and the first motor 342 drives the second connecting rod 341 at its output end to rotate. Because the connecting column 343 set at the free end of the second connecting rod 341 is slidably connected with the guide groove 344 set at one end of the linkage rod 31, when the second connecting rod 341 swings, it will drive the linkage rod 31 to swing through the action of the connecting column 343 and the guide groove 344, and the multiple connecting shafts 32 on the linkage rod 31 drive the multiple wind shields 12 to swing synchronously through multiple mutually parallel first connecting rods 33.

[0049] In this embodiment, according to the specification Figure 2 -Attached Figure 3 It can be seen that the driving assembly 20 includes: an optical axis 21, a screw 22 and a second motor 23. The optical axis 21 is vertically arranged at the top of the inner part of the box body 10, and is slidably connected to and penetrates the first side of the drying box 11; the screw 22 is parallel to the optical axis 21, and is threadedly connected to and penetrates the second side of the drying box 11, and the screw 22 rotates under the drive of the second motor 23.

[0050] The second motor 23 drives the screw 22 to rotate, and the rotation of the screw 22 will drive the drying box 11 threadedly connected thereto to move up and down. The function of the optical axis 21 arranged parallel to the screw 22 is to provide support and guidance, so that the drying box 11 can move up and down along the optical axis 21; when the moisture content of the leather on the stretching plate 14 is high, the height of the drying box 11 can be lowered by turning on the second motor 23 to speed up the drying speed of the leather.

[0051] In this embodiment, according to the specification Figure 4 -Attached Figure 5 It can be seen that each fixing frame 13 is connected to the bottom of the box body 10 through a locking assembly 50. The locking assembly 50 includes a guide plate 51, a clamping head 54 and an adjusting assembly 55. The guide plate 51 is arranged parallel to the fixing frame 13, and a plurality of guide wheels 52 are rotatably arranged on the lower end surface of the guide plate 51 along its length direction. The guide wheels 52 are slidably connected to the limiting grooves 53 arranged at the top of the fixing frame 13. Under the action of the adjusting assembly 55, the clamping head 54 can be lifted and lowered on the fixing frame 13, and a clamping groove 56 corresponding to the clamping head 54 is arranged on the inner bottom surface of the box body 10.

[0052] In order to ensure that the fixing frame 13 can smoothly enter and exit the box body 10 and the fixing frame 13 is arranged in an orderly manner in the box body 10, a limiting groove 53 arranged at the top of each fixing frame 13 is slidably connected to the guide wheel 52 above it. The sliding connection between the guide wheel 52 and the limiting groove 53 can ensure that the fixing frame 13 moves along its length direction on the one hand, and on the other hand, there is rolling friction between the guide wheel 52 and the limiting groove 53, which can reduce the friction force on the fixing frame 13 during movement. By operating the adjustment component 55, the position relationship between the clamping head 54 and the clamping groove 56 is controlled, thereby ensuring that when the fixing frame 13 is outside the box body 10, the position can be fixed.

[0053] In this embodiment, according to the specification Figure 1 -Attached Figure 5 It can be seen that the adjustment assembly 55 includes a rotating shaft 551, a first gear 553, a hand wheel 554, a rack 552 and a reset member 57. The rotating shaft 551 is rotatably arranged at one end of the fixed frame 13 away from the sealing door 17, the rotating shaft 551 is provided with a first gear 553, and the end of the rotating shaft 551 is provided with a hand wheel 554; the rack 552 is vertically arranged in the slideway on the fixed frame 13 and meshes with the first gear 553, and the lower end of the rack 552 is connected to the upper end of the clamp 54; the reset member 57 is arranged on the fixed frame 13 and connected to the rack 552, and the reset member 57 provides a downward force to the rack 552, and the clamping groove 56 is located on the bottom surface of the box body 10 close to the sealing door 17. When the fixed frame 13 is located outside the box body 10, the clamping head 54 is plugged and fixed with the clamping groove 56.

[0054] When the hand wheel 554 is turned, the corresponding rotating shaft 551 and the first gear 553 thereon can be driven to rotate synchronously. During the rotation process, the rack 552 is driven to rise. During the rising process of the rack 552, the clamping head 54 is synchronously driven to rise, thereby separating the clamping head 54 from the clamping slot 56. When the hand wheel 554 is released, the clamping head 54 is reset under the action of the reset member 57 and re-enters the clamping slot 56. The structure is simple and easy to use. When the fixing frame 13 is located outside the box 10, the clamping head 54 is separated from the clamping slot 56, and the leather on the stretching plate 14 is dried in the box 10. When the fixing frame 13 is located outside the box 10, the clamping head 54 is plugged and fixed with the clamping slot 56, and the fixing frame 13 is locked to prevent the fixing frame 13 from shaking when the staff replaces the leather.

[0055] In this embodiment, according to the specification Figure 5It can be seen that the reset member 57 includes a guide sleeve 572, a limiting boss 573, a guide shaft 574 and a spring 575. The connecting plate 571 is arranged at the upper end of the rack 552, and the connecting plate 571 is vertically provided with a guide sleeve 572; the limiting boss 573 is arranged on one side of the fixing frame 13 above the connecting plate 571, and a guide shaft 574 is vertically provided under the limiting boss 573, and the upper end of the guide shaft 574 is sleeved in the guide sleeve 572; the spring 575 is sleeved on the guide sleeve 572, and its two ends respectively abut against the limiting boss 573 and the connecting plate 571.

[0056] When the staff needs to remove the leather on the stretching plate 14, the sealing door 17 is opened, and the stretching plate 14 is pulled outward by pulling the handle 18 on the fixing frame 13. When the clamping head 54 encounters the card slot 56, the spring 575 in a compressed state begins to stretch, thereby driving the connecting plate 571 to descend while driving the clamping head 54 to descend. The clamping head 54 is inserted into the card slot 56, and the clamping head 54 is adapted to the card slot 56, and the fixing frame 13 is locked. When the staff takes and places the leather, the fixing frame 13 will not shake, which is convenient for the staff to replace the leather. After the new leather is fixed on the stretching plate 14, the hand wheel 554 is turned, and the clamping head 54 is driven to rise through the cooperation of the first gear 553 and the rack 552, and the lock between the clamping head 54 and the card slot 56 is released. At the same time, the spring 575 is compressed, and the staff pushes the fixing frame 13 inward to the drying position, closes the sealing door 17, and dries the new leather.
