Description

Technical Field

[0001] The present invention relates to the technical field of backpack production and processing, in particular to a high-efficiency drying device for backpack processing. Background Art

[0002] During backpack manufacturing, in order to improve the production quality, some manufacturers will clean and disinfect the backpacks after production. After cleaning, they are often placed in an open air environment to be exposed to the sun or air-dried. This not only has low drying efficiency but is also easily contaminated by external dust. When drying in an oven, the backpack is often placed directly in it, and only the outside of the backpack is dried unilaterally. In order to improve the protective performance, existing backpacks are usually made of dense fabrics such as leather, plastic, polyester, canvas, nylon and cotton and linen, so the sealing performance is very good. Therefore, only the outside of the backpack is dried, and the drying efficiency is low.

[0003] After searching, the Chinese patent application number CN202122257775.5 discloses a drying device for backpack processing, including a bracket, a mounting frame fixedly installed on the top of the bracket, and a circular hollow plate fixedly installed on the bottom inner wall of the mounting frame. However, since the above technical solution directly places the backpack in the oven for drying, the hot air cannot quickly penetrate the surface of the backpack and enter the interior of the backpack to quickly dry the interior of the backpack, resulting in the backpack needing to be placed in the oven for a long time to be thoroughly dried. Therefore, there is still a problem of low backpack drying efficiency. Summary of the Invention

[0022] The beneficial effects of the present invention are:

[0023] 1. The present invention arranges an arc-shaped metal spring plate inside the second installation box and the first installation box that can be extended and retracted following the forward and backward movement of the movable plate. When the movable plate moves forward, it can push the arc-shaped metal spring plates on the inner walls of the second installation box and the first installation box to move obliquely downward and obliquely upward respectively, quickly propping up the four corners of the interior of the backpack and fully opening the interior of the backpack. At the same time, when the movable plate moves forward, it can also push the second installation box and the first installation box to move upward at a certain height at a uniform speed through the cylinder, so that the second installation box and the first installation box can move to the center of the interior of the expanded backpack, so that the electric heating plate brackets on the outer walls of the second installation box and the first installation box can quickly dry all corners of the interior of the backpack, while preventing the internal structure of the backpack from contacting the electric heating plate bracket with a higher temperature, thereby improving the drying efficiency of the backpack and preventing the internal structure of the backpack from being scalded by the electric heating plate.

[0024] 2. When the movable plate is pushed to the inner wall of one side of the oven, the L-shaped plate on one side of the movable frame will also rest against the connecting piece connected to the guide plate. At this time, the conductive joint on one side of the L-shaped plate and the conductive joint on one side of the connecting piece are connected, allowing the current to be transmitted to the electric heating plate on the outer wall of the electric heating plate bracket through the conductive joint and the transmission line inside the connecting piece to dry the inside of the backpack body. After the backpack body is dried, the staff pulls back the movable plate to release the connection between the two conductive joints, so that the electric heating plate on the electric heating plate bracket is quickly powered off and turned off, so that the electric heating plate on the outer wall of the electric heating plate bracket is heated only when the backpack body is inserted into the oven, thereby improving the safety of the drying device when in use.

[0025] 3. The staff will carry the backpack body that needs to be dried after cleaning on one side of the movable frame through the card plate, and then rotate the movable frame as a whole downward through the damping bearing, so that the positioning plate moves to the side of the positioning block, and then insert the positioning plate and the positioning block together through the pin to limit the movable frame moved to the top of the movable plate. At this time, the card plate and the friction plate will clamp and fix the shoulder straps of the backpack body through the elastic force provided by the third elastic telescopic rod and the second elastic telescopic rod on one side, so that the backpack body as a whole is stably covered on one side of the movable frame.

[0026] 4. When the movable plate moves to the outer wall of one side of the metal sheet, the first elastic telescopic rod will block the movable plate through its own elastic force. At this time, the magnet sheet will be adsorbed on one side of the metal sheet through its own magnetic force, thereby limiting the entire movable plate inserted into the oven.

[0027] 5. When the staff pushes the movable plate forward, the movable plate will squeeze the elastic airbag. After being squeezed, the elastic airbag will send the internal gas into the cylinder through the pipeline, thereby slowly pushing the guide plate upward through the cylinder, thereby driving the multiple second installation boxes and the first installation box on one side of the guide plate to slowly move upward, so as to prevent the bottom of the second installation box and the first installation box from scratching the interlayer or functional bag provided on the inner wall of the backpack body when the backpack body moves forward.

An elastic airbag 20 is provided on the inner wall of the guide groove 22, and the elastic airbag 20 is connected to the input end of the cylinder 41 through a pipeline.

[0042] Fixed blocks 32 are fixed at the diagonal inner walls of the second installation box 13 and the first installation box 14. A winding drum 35 is rotatably connected to the outer wall of one side of the fixed block 32. An elastic metal sheet 34 is wound around the outer wall of the winding drum 35. One end of the elastic metal sheet 34 is fixed to the outer wall of the winding drum 35, and the other end of the elastic metal sheet 34 is fixed to an arc-shaped metal spring plate 37. Rectangular through holes are provided on the outer walls of both sides of the first installation box 14 and the second installation box 13 for the arc-shaped metal spring plate 37 to pass through. A pushing mechanism is provided on the outer walls of the movable plate 2, the second installation box 13, the first installation box 14 and the oven 8. The arc-shaped metal spring plate 37 connected to the inner wall of the first installation box 14 is bent upward, and the arc-shaped metal spring plate 37 connected to the inner wall of the second installation box 13 is bent downward.

[0043] The pushing mechanism includes an internal threaded sleeve 7, a support frame 42, a rotating shaft 19, a lead screw 21, a first gear 16, a first rack plate 29, a telescopic guide rod 30, a push rod 31, a connecting plate 33, a second rack plate 39 and a second gear 38.

[0044] The internally threaded sleeve 7 is fixed on the top outer wall of the movable plate 2, the support frame 42 is fixed on the top outer wall of the base 1, the rotating shaft 19 is rotatably connected to the inner wall of the support frame 42, the first gear 16 is fixed on the outer wall on one side of the rotating shaft 19, and the screw 21 is fixed on the outer wall on the other side of the rotating shaft 19. The internally threaded sleeve 7 and the screw 21 are on the same axis, and the thread lead angle of the screw 21 is greater than the equivalent friction angle of the internally threaded sleeve 7.

[0045] The telescopic guide rod 30 is slidably connected to an inner wall of one side of the oven 8, the first rack plate 29 is fixed to the bottom outer wall of the telescopic guide rod 30, the first rack plate 29 is meshed with the first gear 16, the push rod 31 is fixed to the telescopic end of the telescopic guide rod 30, and multiple connecting plates 33 are respectively fixed to the top outer wall of the push rod 31, and the connecting plates 33 respectively pass through the bottom outer walls of the second installation box 13 and the first installation box 14, the second rack plate 39 is fixed to the outer wall of one side of the connecting plate 33, the second gear 38 is fixed to the outer wall of one side of the winding drum 35, and the second rack plate 39 is meshed with the second gear 38.

[0046] The second rack plate 39 provided on the inner wall of the first installation box 14 is located below the second gear 38 , and the second rack plate 39 provided on the inner wall of the second installation box 13 is located above the second gear 38 .

[0047] The staff first puts the straps of the backpack body 4 to be dried on the backpack fixing mechanism on the outer wall of the movable frame 3, then unzips the zipper at the opening of the backpack body 4, and then pushes the movable frame 3 downward to a position parallel to the outer wall of the top of the movable plate 2, and clamps and fixes the straps of the backpack body 4 through the backpack fixing mechanism. At this time, the opening of the backpack body 4 faces the opening on the side of the drying oven 8.

[0048] Then the staff pushes the movable plate 2 forward as a whole. When the movable plate 2 moves to the side of the elastic airbag 20, the internal threaded sleeve 7 located on the top of the movable plate 2 will also move to the side of the screw 21. At this time, the multiple staggered second installation boxes 13 and one end of the first installation box 14 fixed on one side of the guide plate 15 will also move to the opening of the backpack body 4.

[0049] Then the staff continues to push the movable plate 2 forward. At this time, the movable plate 2 will squeeze the elastic airbag 20. After being squeezed, the elastic airbag 20 will send the internal gas into the cylinder 41 through the pipeline, and the cylinder 41 will slowly push the guide plate 15 upward, thereby driving the multiple second installation boxes 13 and the first installation box 14 on one side of the guide plate 15 to move slowly upward, so as to prevent the second installation box 13 and the first installation box 14 from rubbing against the interlayer or functional bag provided on the inner wall of the backpack body 4 when the backpack body 4 moves forward. After the movable plate 2 is pushed to the inner wall of one side of the oven 8, the backpack body 4 as a whole will also enter the inner wall of the oven 8. At this time, the cylinder 41 will also push the second installation box 13 and the first installation box 14 to rise to the middle part of the backpack body 4, so that the electric heating plate bracket 40 on the outer wall of the second installation box 13 and the first installation box 14 can evenly heat the inner wall of the backpack body 4. The staff can replace the elastic airbags 20 of different sizes according to the different sizes of the backpack body 4 and adjust the distance that the cylinder 41 pushes the guide plate 15 upward.

[0050] When the movable plate 2 continues to move forward under the push of the staff, the internal threaded sleeve 7 located at the top of the movable plate 2 will also drive the screw 21 on the inner wall to rotate through the thread, thereby driving the first gear 16 on one side of the rotating shaft 19 to rotate through the screw 21. When the first gear 16 rotates, it will drive the telescopic guide rod 30 and the push rod 31 to move away from the cylinder 41 through the first rack plate 29 engaged therewith, thereby driving the connecting plate 33 and the second rack plate 39 on one side to move forward.

[0051] When the second rack plate 39 located on the inner wall of the first installation box 14 moves forward, it drives the winding drum 35 to rotate clockwise, so that the winding drum 35 pushes the arc-shaped metal spring plate 37 to move obliquely upward to the outer walls on both sides of the first installation box 14 through the elastic metal sheet 34 wound on the outer wall. The second rack plate 39 located on the inner wall of the second installation box 13 drives the winding drum 35 on the inner wall of the second installation box 13 to rotate counterclockwise, thereby pushing the arc-shaped metal spring plate 37 on the inner wall of the second installation box 13 to move obliquely downward, thereby passing through the multiple arc-shaped metal spring plates 37 on one side of the guide plate 15 that move obliquely upward and obliquely downward respectively. The four corners of the inner wall of the backpack body 4 are propped up, so that under the push of the cylinder 41 and the expansion of the arc-shaped metal spring plate 37, the second installation box 13 and the first installation box 14 are brought to the center of the backpack body 4, so that the electric heating plate bracket 40 on the outer wall of the second installation box 13 and the first installation box 14 can quickly dry every corner of the backpack body 4, while preventing the internal structure of the backpack body 4 from contacting the electric heating plate bracket 40 with a higher temperature, thereby improving the drying efficiency of the backpack body 4 and preventing the internal structure of the backpack body 4 from being scalded by the electric heating plate on the electric heating plate bracket 40.

[0052] After the set time, the staff pulls the movable plate 2 outward. At this time, the cylinder 41 will discharge the internal gas into the elastic airbag 20 under the action of the gravity of the guide plate 15, so that the guide plate 15 moves downward at a uniform speed and resets. At the same time, the internal threaded sleeve 7 moving back will also drive the screw 21 to rotate in the opposite direction, so that the push rod 31 drives the second rack plate 39 on one side to move back and reset, thereby driving the winding drum 35 to rotate in the opposite direction and reset. The elastic metal sheet 34 on the outer wall of the winding drum 35 pulls the arc-shaped metal spring plates 37 on both sides of the second installation box 13 and the first installation box 14 back to their initial positions on one side, so that the dried backpack body 4 can be smoothly pulled out of the oven 8, thereby completing the rapid drying of the backpack body 4; the inner wall of the oven 8 is evenly provided with electric heating plates of the same model as those on the electric heating plate bracket 40, so as to cooperate with the electric heating plates on the outer wall of the electric heating plate bracket 40 to quickly dry the inside and outside of the backpack body 4.

[0053] like Figure 1-2As shown, the backpack fixing mechanism includes a movable block 28 , a third elastic telescopic rod 27 , a clamping plate 10 , a positioning plate 6 , a second elastic telescopic rod 26 , a friction plate 24 , a positioning block 11 and a latch 25 .

[0054] The second elastic telescopic rod 26 is fixed to the top outer wall of the movable plate 2 , and the friction plate 24 is fixed to the top outer wall of the second elastic telescopic rod 26 .

[0055] The movable block 28 is slidably connected to the outer walls of both sides of the movable frame 3 , the third elastic telescopic rod 27 is fixed to one outer wall of the movable block 28 , and the clamping plate 10 is fixed to one outer wall of the third elastic telescopic rod 27 .

[0056] The positioning plate 6 is fixed to one side outer wall of the movable frame 3 , the positioning block 11 is fixed to the top outer wall of the movable plate 2 , and the latch 25 is plugged into the positioning block 11 and one side outer wall of the positioning plate 6 .

[0057] The staff will carry the backpack body 4 that needs to be dried after cleaning on one side of the movable frame 3 through the card plate 10, and then rotate the movable frame 3 as a whole downward through the damping bearing, so that the positioning plate 6 moves to the side of the positioning block 11, and then insert the positioning plate 6 and the positioning block 11 together through the pin 25 to limit the movable frame 3 moved to the top of the movable plate 2. At this time, the card plate 10 and the friction plate 24 will clamp and fix the shoulder straps of the backpack body 4 through the elastic force provided by the third elastic telescopic rod 27 and the second elastic telescopic rod 26 on one side, so that the backpack body 4 as a whole is stably covered on one side of the movable frame 3.

[0058] like Figure 1 As shown, a rectangular through slot is provided on the top outer wall of the oven 8, and an exhaust fan 9 is provided on the inner wall of the rectangular through slot; the exhaust fan 9 can quickly extract the steam generated when the backpack body 4 is dried inside the oven 8.

[0059] like Figure 2 As shown, a magnet sheet 23 is fixed to the outer wall of one side of the movable plate 2, a first elastic telescopic rod 17 is fixed to the inner wall of one side of the oven 8, and a metal sheet 18 is fixed to the outer wall of one side of the first elastic telescopic rod 17; when the movable plate 2 moves to the outer wall of the metal sheet 18, the first elastic telescopic rod 17 will block the movable plate 2 by its own elastic force. At this time, the magnet sheet 23 will be adsorbed on the side of the metal sheet 18 by its own magnetic force, thereby limiting the entire movable plate 2 inserted into the oven 8.

[0060] like Figure 3 As shown, a conical head 12 is fixed to the outer wall of one side of the first installation box 14; the conical head 12 can guide the first installation box 14 inserted into the opening of the backpack body 4, so that the first installation box 14 can smoothly pass through the opening of the backpack body 4 and enter the interior of the backpack body 4.

[0061] like Figure 4 As shown, a buffer strip 36 is fixed to the outer wall of one side of the arc-shaped metal spring plate 37; the buffer strip 36 can buffer the contact surface between the arc-shaped metal spring plate 37 and the inside of the backpack body 4, thereby improving the supporting effect of the arc-shaped metal spring plate 37 on the inner wall of the backpack body 4.

[0062] When using this embodiment, the staff first puts the straps of the backpack body 4 to be dried on the backpack fixing mechanism on the outer wall of the movable frame 3, then unzips the zipper at the opening of the backpack body 4, and then pushes the movable frame 3 downward to a position parallel to the outer wall of the top of the movable plate 2, and clamps and fixes the straps of the backpack body 4 through the backpack fixing mechanism.

[0063] Then the staff continues to push the movable plate 2 forward. At this time, the movable plate 2 will squeeze the elastic airbag 20. After being squeezed, the elastic airbag 20 will send the internal gas into the cylinder 41 through the pipeline, thereby slowly pushing the guide plate 15 upward through the cylinder 41, driving the multiple second installation boxes 13 and the first installation box 14 on one side of the guide plate 15 to slowly move upward. When the movable plate 2 is pushed to the inner wall of one side of the oven 8, the backpack body 4 as a whole will also enter the inner wall of the oven 8. At this time, the cylinder 41 will also push the second installation box 13 and the first installation box 14 to rise to the middle part inside the backpack body 4.

[0064] When the movable plate 2 continues to move forward under the push of the staff, the internal threaded sleeve 7 located at the top of the movable plate 2 will also drive the screw 21 on the inner wall to rotate through the thread, thereby driving the first gear 16 on one side of the rotating shaft 19 to rotate through the screw 21. When the first gear 16 rotates, it will drive the telescopic guide rod 30 and the push rod 31 to move away from the cylinder 41 through the first rack plate 29 engaged therewith, thereby driving the connecting plate 33 and the second rack plate 39 on one side to move forward.

[0065] When the second rack plate 39 located on the inner wall of the first installation box 14 moves forward, it will drive the winding drum 35 to rotate clockwise, so that the winding drum 35 pushes the arc-shaped metal spring plate 37 to move obliquely upward toward the outer walls on both sides of the first installation box 14 through the elastic metal sheet 34 wound on the outer wall. The second rack plate 39 located on the inner wall of the second installation box 13 will drive the winding drum 35 on the inner wall of the second installation box 13 to rotate counterclockwise, thereby pushing the arc-shaped metal spring plate 37 on the inner wall of the second installation box 13 to move obliquely downward, thereby supporting the four corners of the inner wall of the backpack body 4 through the multiple arc-shaped metal spring plates 37 on one side of the guide plate 15 that move obliquely upward and downward respectively. Under the push of the cylinder 41 and the expansion action of the arc-shaped metal spring plates 37, the second installation box 13 and the first installation box 14 are brought to the center of the interior of the backpack body 4, so that the electric heating plate bracket 40 on the outer walls of the second installation box 13 and the first installation box 14 can quickly dry every corner inside the backpack body 4.

[0066] After the set time, the staff pulls the movable plate 2 outward. At this time, the cylinder 41 will discharge the internal gas into the elastic airbag 20 under the action of the gravity of the guide plate 15, so that the guide plate 15 moves downward at a uniform speed and resets. At the same time, the internal threaded sleeve 7 moving back will also drive the screw 21 to rotate in the opposite direction, so that the push rod 31 drives the second rack plate 39 on one side to move back and reset, thereby driving the winding drum 35 to rotate in the opposite direction and reset. The elastic metal sheet 34 on the outer wall of the winding drum 35 pulls the arc-shaped metal spring plates 37 on both sides of the second installation box 13 and the first installation box 14 back to the initial position on one side, so that the dried backpack body 4 can be smoothly pulled out from the inside of the oven 8, thereby completing the rapid drying of the backpack body 4.

[0067] Example 2:

[0068] An efficient drying device for backpack processing, such as Figure 2 、 Figure 3 、 Figure 6 and Figure 7 As shown, an L-shaped plate 5 is fixed to the outer wall of one side of the movable frame 3, and a connecting piece 43 is fixed to the outer wall of one side of the cylinder 41. The top outer wall of the connecting piece 43 is slidably connected to the inner wall of the guide plate 15. The connecting piece 43 and the outer wall of one side of the L-shaped plate 5 are respectively provided with conductive joints 44, and the conductive joints 44 are electrically connected to the electric heating plate on the electric heating plate bracket 40.

[0069] After the staff covers the movable frame 3 with the backpack body 4 on the top of the movable plate 2, they can push the movable plate 2 forward. When the movable plate 2 is pushed to the inner wall of one side of the oven 8, the L-shaped plate 5 on one side of the movable frame 3 will also rest on the connecting piece 43 connected to the guide plate 15. At this time, the conductive connector 44 on one side of the L-shaped plate 5 and the conductive connector 44 on one side of the connecting piece 43 are connected, and one side of the L-shaped plate 5 is connected to the mains through a power transmission line, so that the current is transmitted to the electric heating plate on the outer wall of the electric heating plate bracket 40 through the conductive connector 44 and the transmission line inside the connecting piece 43 to dry the inside of the backpack body 4. After the drying of the backpack body 4 is completed, the staff pulls back the movable plate 2 to release the connection between the two conductive connectors 44, so that the electric heating plate on the electric heating plate bracket 40 is quickly powered off and turned off, so that the electric heating plate on the outer wall of the electric heating plate bracket 40 is heated only when the backpack body 4 is inserted into the inside of the oven 8, thereby improving the safety of the drying device when in use.
