Description

Technical Field

[0001] The invention relates to the technical field of wooden pallet production, and in particular to a fully automatic drying production line for wooden pallet processing. Background Art

[0002] Wooden pallets are pallets made of natural wood. They are the most widely used pallets. Pallets are horizontal platform devices used for packaging, stacking, handling and transportation of goods and products as unit loads. In the production process of wooden pallets, in order to ensure the quality of wooden pallets and extend their service life, the moisture (water content) in the wooden pallets must be reduced to a certain level, which requires drying treatment, and then the use of wooden pallet drying equipment.

[0003] The patent with publication number CN115615162B discloses a drying device for processing wooden pallets, including a main body mechanism, on which a driving mechanism is installed; a drying mechanism is connected to the driving mechanism; a supporting mechanism is provided on the main body mechanism; a resistance mechanism is installed on the supporting mechanism; a limiting mechanism is connected to the supporting mechanism; when the supporting mechanism is started, the resistance mechanism slides into the inside of the supporting mechanism, and the control switch of the resistance mechanism is turned on to make it resist the pallet, thereby facilitating the improvement of the drying effect of the pallet; when the main body mechanism is working, the driving mechanism is started, and then the driving mechanism drives the drying mechanism to slide inside the main body mechanism, thereby facilitating the drying of various parts of the pallet; when disassembling the pallet, the supporting mechanism is started, so that the resistance mechanism drives the limiting mechanism to slide while driving the resistance mechanism to move, thereby facilitating the limiting mechanism to be limited, which is beneficial to prevent the displacement of the supporting mechanism when disassembling the pallet.

[0004] However, the above prior art has the following technical defects:

[0005] 1. The traditional way to fix the wooden strips on the top of the wooden pallet and the supporting wooden strips on the bottom is to rely on rivets. However, during the drying process of the wooden pallet, rivets or other metal parts may protrude. This is mainly because the wood loses moisture during drying, causing the wood to shrink. If the rivets, screws or other metal parts used on the wooden pallet are not firmly bonded to the wood, or the speed of wood shrinkage is greater than the change of the metal parts, the rivets or metal parts may protrude. When goods are subsequently placed on the wooden pallet, the protruding rivets may damage the items. However, this device or other traditional drying equipment does not have a device to detect protruding rivets, which may cause wooden pallets with protruding rivets to enter the market.

[0006] Second, before using this device, the user needs to stack the wooden pallets in order in the support frame. After the equipment has finished drying the wooden pallets, the staff is required to manually take out the multiple wooden pallets stacked in the equipment. As a result, the equipment itself has a low degree of automation, resulting in a large workload for the staff.

DETAILED DESCRIPTION

[0041] The following is combined with Figure 1 - Fig.16 Embodiments of the present invention are described in detail.

[0042] The embodiment of the present application discloses a fully automatic drying production line for processing wooden pallets. Through the cooperation of a conveying mechanism and a detection mechanism, it is possible to detect whether there are extended rivets on the upper surface of the wooden pallet after drying. At the same time, after the detection is completed, the conveying mechanism can change the conveying direction of the wooden pallet. The wooden pallet with extended rivets is sent out from the third conveyor belt, and the wooden pallet without extended rivets is sent out from the second conveyor belt. Automatic classification is achieved on whether there are extended rivets on the upper surface of the wooden pallet, thereby preventing the wooden pallets with extended rivets from entering the market and improving the quality of the finished wooden pallets.

[0043] Embodiment 1:

[0044] like Figure 3 and Figure 5 As shown, it includes a conveying mechanism 1, which includes a mounting seat 101. A plurality of groups of evenly distributed first gears 104 are arranged in the cavity of the mounting seat 101. Two electric push rods 103 are installed on the side of the mounting seat 101. The telescopic arms of the two electric push rods 103 extend into the cavity and are installed with a mounting plate 109. The telescopic arms of the electric push rods 103 can drive the mounting plate 109 to move.

[0045] like Figure 5-Figure 7 As shown, the side surface of the mounting plate 109 is provided with a first rack 105 meshing with the first gear 104 in each group on one side of each group of first gears 104, and an L-shaped seat 106 is installed at the center of the upper side of each first gear 104. The movable mounting plate 109 drives each first rack 105 to move, and each moving first rack 105 can drive the first gear 104 meshing therewith to rotate.

[0046] like Figure 8 As shown, a motor 107 is installed on the side of each L-shaped seat 106, and the driving end of each motor 107 passes through the vertical plate of the L-shaped seat 106 and is installed with a conveying ball 108 extending to the outside of the mounting seat 101, and the center of the conveying ball 108 is aligned with the center of the first gear 104. The rotating first gear 104 can drive the conveying ball 108 to deflect around its center through the L-shaped seat 106, and the running motor 107 can drive the conveying ball 108 to rotate.

[0047] like Figure 3 As shown, the conveying mechanism 1 also includes two side plates 102 installed on the upper edge of the mounting seat 101, and a group of second pressure sensors 113 are installed on the side of each side plate 102. Bar grooves 111 are opened on both sides of the mounting seat 101 near the two ends of the mounting plate 109. A controller 112 is installed on the side of the mounting seat 101 on one side of the detection mechanism 2. The two side plates 102 can limit the wooden pallet moving on the mounting seat 101. When the moving wooden pallet squeezes the second pressure sensor 113 on one side, a signal is sent to the controller 112, and the controller 112 controls the extension and retraction of the electric push rod 103.

A spring 204 is sleeved on each slide bar 203 between the limiting plate 205 and the C-shaped plate 201. One end of each spring 204 is fixedly connected to the C-shaped plate 201, and the other end is fixedly connected to the limiting plate 205. The moving intercepting plate 202 drives the two limiting plates 205 to move through the two slide bars 203, and then lengthens the spring 204 through the two limiting plates 205. When the rivet releases the squeezing of the intercepting plate 202, the two springs 204 shorten and drive the intercepting plate 202 to restore its position.

[0050] like Figure 1-Figure 2 and Figure 9-10 As shown, a driving mechanism 3 is provided on the side of the mounting seat 101, and the driving mechanism 3 includes two rectangular rods 301 installed on both sides of the mounting seat 101 and close to the C-shaped plate 201, and a movable block 302 fixedly connected to the C-shaped plate 201 is slidably provided on each rectangular rod 301. The movable block 302 can drive the C-shaped plate 201 to rise and fall while sliding on the rectangular rod 301.

A fourth rack 312 meshing with the third gear 311 is installed on the side of each movable block 302. The rotating second gear 310 can drive the third gear 311 to rotate through the rotating rod 309, and the rotating third gear 311 drives the movable block 302 to move through the fourth rack 312.

[0052] like Figure 9-10As shown, a group of first sliding bars 305 are installed on both sides of the mounting base 101, and a first slider 306 is slidably set on each first sliding bar 305, and a second rack 307 located below and matched with the second gear 310 is installed on the side of each lower first sliding bar 306, and a third rack 308 located above and matched with the second gear 310 is installed on the side of each upper first sliding bar 306. The lower first sliding bar 306 is located at the end of the first sliding bar 305 close to the magnetic block 304, and the upper first sliding bar 306 is located at the end of the first sliding bar 305 away from the magnetic block 304. The moving second rack 307 and the third rack 308 can both drive the second gear 310 to rotate, and at the same time, the moving second rack 307 and the third rack 308 can drive the corresponding first sliding bar 306 to slide on the first sliding bar 305.

The movable mounting plate 109 can drive the magnetic block 304 to move through the mounting rod 303. The magnetic block 304 moving toward the movable block 302 can drive the second rack 307 to move, and the magnetic block 304 moving toward the electric push rod 103 can drive the third rack 308 to move.

[0054] like Figure 1-Figure 2 , Fig.13 and Fig.15 As shown, a box mechanism 4 is provided on one side of the conveying mechanism 1, and the box mechanism 4 includes a box 401. An outlet 407 is opened on one side of the box 401, and an entrance aligned with the outlet 407 is provided on the other side of the box 401. A box door 408 is provided in the entrance, and wooden pallets can be sent in from the entrance and sent out from the outlet 407.

[0055] like Fig.13 and Fig.15 As shown, two sets of shafts 402 are rotatably installed on both sides of the outlet 407 inside the box 401, and motors 403 are installed on one side of the upper two shafts 402 on the side of the box 401. The driving end of each motor 403 is fixedly connected to the end of the alignment shaft 402. The two running motors 403 can drive the two shafts 402 connected thereto to rotate.

[0056] like Fig.13 and Fig.15As shown, two sets of synchronous wheels 404 are installed on the side of each set of two shafts 402, and a synchronous belt 405 is commonly provided on each set of two synchronous wheels 404. A set of support plates 406 is installed on the side of each two synchronous belts 405 on the same side. The two rotating shafts 402 can drive the four synchronous belts 405 to rotate, thereby driving the two sets of support plates 406 to move.

[0057] like Figure 1-Figure 2 and Fig.16 As shown, a hot air mechanism 5 is arranged above the box mechanism 4, and the hot air mechanism 5 includes a heating box 501 installed on the upper side of the box body 401, and a plurality of evenly distributed electric heating wires 502 are arranged in the heating box 501. A blower 505 with an output end connected to it is arranged on the upper side of the heating box 501 and on one side of the heating box 501. The running electric heating wires 502 convert electrical energy into thermal energy and emit heat, and the blower 505 can send wind into the heating box 501 and convert it into hot air.

[0058] like Figure 1-Figure 2 and Fig.16 As shown, an output pipe 503 is installed on the other side of the heating box 501, and a plurality of branch pipes 504 connected to the box body 401 are installed on the side of the output pipe 503. The hot air in the heating box 501 is delivered into the box body 401 through the output pipe 503 and the branch pipes 504.

[0059] like Figure 1-Figure 2 and Fig.16 As shown, a first conveyor belt 10 is provided on one side of the conveying mechanism 1, which passes through the opening of the box body 401 and passes through the outlet 407, and an adjacent second conveyor belt 11 and a third conveyor belt 12 are provided on the other side of the conveying mechanism 1. The second conveyor belt 11 and the third conveyor belt 12 are exactly the same in model. The first conveyor belt 10 is used for conveying wooden pallets in the box body 401, the second conveyor belt 11 is used for conveying wooden pallets without protruding rivets, and the third conveyor belt 12 is used for conveying wooden pallets with protruding rivets.

[0060] Embodiment 2: Figure 1-Figure 2 and Fig.14 As shown, on the basis of Example 1, in order to enhance the linkage between the box mechanism 4 and the conveying mechanism 1, two second sliding bars 6 are installed on the side of the box body 401 corresponding to the port of the outlet 407, and a second sliding block 7 is slidably arranged on each second sliding bar 6, and a baffle 8 for blocking the outlet 407 is installed between the two second sliding blocks 7, and the baffle 8 is used to block the outlet 407, and the moving baffle 8 can drive the two second sliding blocks 7 to slide on the two second sliding bars 6.

[0061] like Figure 1-Figure 2 and Fig.14As shown, two 13 are correspondingly provided on the side of the baffle 8, and two connecting plates 9 extending into the two 13 are correspondingly installed on the upper side of the C-shaped plate 201. When the C-shaped plate 201 rises, the baffle 8 is driven to rise through the two connecting plates 9, and when the C-shaped plate 201 descends, the baffle 8 is driven to descend through the connecting plates 9.

[0062] The working principle of this fully automatic drying production line for pallet processing is:

[0063] S1. Send in pallets. Send multiple wooden pallets into the box 401. Each of the two pallets 406 of the same height can hold a wooden pallet. Specifically, open the box door 408 on the side of the box 401 to open the entrance, and then place the wooden pallet on the first conveyor belt 10. The running first conveyor belt 10 transports the wooden pallet into the box 401. Then, the two motors 403 drive the two shafts 402 to rotate toward the outside of the two shafts, and then drive the four synchronous belts 405 to rotate through eight synchronous wheels 404, driving the two groups of pallets 406 to move in the corresponding synchronous belts 405 in the rotation direction, and the two pallets 406 of the same height lift the wooden pallet on the first conveyor belt 10 to drive it to rise, and then repeat the rising operation so that each of the two pallets 406 of the same height can hold the wooden pallet, thereby realizing automatic loading of wooden pallets.

[0064] S2, pallet drying, the hot air mechanism 5 sends hot air into the box body 401 to dry the wooden pallet. Specifically, the running blower 505 sends air into the heating box 501, and at the same time the electric heating wire 502 in the heating box 501 converts electrical energy into thermal energy to emit heat. The wind entering the heating box 501 absorbs heat and becomes hot air, which is sent into the box body 401 through the output pipe 503 and the branch pipe 504, thereby increasing the temperature in the box body 401 and drying the wooden pallet therein.

[0065] S3, pallet delivery, multiple wooden pallets in the heating box 501 are automatically delivered from the inside of the box 401 through the first conveyor belt 10. Specifically, when the wooden pallets are dried, the baffle 8 is pulled up to make it rise so that the outlet 407 is opened, and then the two motors 403 drive the two shafts 402 to rotate toward the inner side of the two, so that the two groups of pallets 406 move downward. When the wooden pallets supported by the two lowest pallets 406 fall on the first conveyor belt 10, the running first conveyor belt 10 delivers the wooden pallets from the outlet 407, and then the other two pallets 406 that continue to descend continue to place the wooden pallets on the first conveyor belt 10, and continue to use the first conveyor belt 10 to deliver them, and repeat the operation until all the wooden pallets in the box 401 are automatically delivered.

[0066] S4, pallet detection, detect whether there are rivets extending from the upper surface of the wooden pallet passing through the conveying mechanism 1 to classify the wooden pallet. Specifically, the wooden pallet is sent to the conveying mechanism 1 through the first conveyor belt 10, and each motor 107 in the conveying mechanism 1 drives the conveying ball 108 to rotate. When the wooden pallet moves to the mounting seat 101, the rotating conveying ball 108 under the wooden pallet conveys the wooden pallet, allowing the wooden pallet to move on the mounting seat 101.

[0067] When the rivets on the upper surface of the wooden pallet extend due to drying, the length from the lower surface of the interception plate 202 to the conveying ball 108 is the same as the height of the wooden pallet, and the interception plate 202 will intercept the rivets on the wooden pallet. The advancing wooden pallet drives the interception plate 202 to move through the rivets, stretching the spring 204 while squeezing the first pressure sensor 206. After being squeezed, the first pressure sensor 206 sends a signal to the controller 112, and the controller 112 controls the electric push rod 103 to extend, and then moves through all the first racks 105, driving Each meshing first gear 104 rotates, thereby driving each conveying ball 108 to deflect to one side of the third conveyor belt 12, and then the wooden pallet changes from moving forward to deflecting to one side through each deflected conveying ball 108. When the wooden pallet hits the second pressure sensor 113 on the side of the side plate 102, the electric push rod 103 shortens and drives the mounting plate 109 to restore its position, thereby driving each conveying ball 108 to rotate and restore, allowing the wooden pallet to continue to move forward and fall onto the third conveyor belt 12. The staff collects the wooden pallets with rivets protruding from the third conveyor belt 12.

[0068] When there are no rivets extending from the surface of the wooden pallet, it will pass directly under the interception plate 202, and then the electric push rod 103 will shorten to drive each conveying ball 108 to deflect toward the side of the second conveyor belt 11, thereby allowing the wooden pallet to deflect toward the side of the second conveyor belt 11. When the wooden pallet hits the second pressure sensor 113 on the same side, the electric push rod 103 will extend to drive the mounting plate 109 to restore its position and drive the conveying ball 108 to restore its rotation direction, allowing the wooden pallet to move forward and fall onto the second conveyor belt 11. The staff will collect the wooden pallets on the second conveyor belt 11 that have no rivets extending.

[0069] S5. Release the limit. During the extension and retraction process of the electric push rod 103, the intercepting plate 202 is driven to rise and fall. Specifically, while the electric push rod 103 is extended, the movable mounting plate 109 drives the second rack 307 to move toward the movable block 302 through the mounting rod 303, the magnetic block 304 and the general 313 on the second rack 307. The movable second rack 307 engages with the second gear 310 and drives it to rotate. The rotating second gear 310 drives the third gear 311 to rotate through the rotating rod 309, and drives the movable block 302 to rise through the fourth rack 312, driving the C-shaped plate 201 and the intercepting plate 202 to rise. When rivets extend from the wooden pallet, the limit can be released. After that, when the electric push rod 103 shortens and drives the mounting plate 109 to restore its position, it drives the second rack 307 to move in the opposite direction, drives the second gear 310 to reverse, so that the third gear 311 reverses and drives 321 to descend, driving the C-shaped plate 201 to descend until the position is restored.

[0070] When the electric push rod 103 is shortened, the third rack 308 is driven to move through the mounting rod 303 and the magnetic block 304. The moving third rack 308 drives the second gear 310 to rotate, and the third gear 311 is driven to rotate through the rotating rod 309, driving the fourth rack 312 to rise. The rising fourth rack 312 drives the C-shaped plate 201 to rise. Afterwards, when the electric push rod 103 extends and drives the mounting plate 109 to restore its position, it further drives the C-shaped plate 201 to restore its position.

[0071] S6, outlet switch, during the lifting and lowering process of the U-shaped plate 201, the baffle plate 8 is driven to lift and lower so that the outlet 407 of the box body 401 is opened and closed. Specifically, when the U-shaped plate 201 is lifted, the baffle plate 8 is driven to lift through the connecting plate 9 to open the outlet 407, and then the next wooden pallet can be sent out from the box body 401. The U-shaped plate 201 is lowered to drive the baffle plate 8 to lower and re-block the outlet 407, so as to avoid the rapid loss of heat in the box body 401 and prepare for the next drying.
