Description

Technical Field

[0001] The present application relates to the technical field of sandpaper drying equipment, and in particular to a sandpaper drying equipment. Background Art

[0002] Sandpaper is an abrasive tool made by attaching an abrasive material to a soft base material with an adhesive. The main raw materials for sandpaper are base paper, abrasive material, and adhesive. To improve the abrasive strength of sandpaper, the base paper must not only be strong, but also wear-resistant, fold-resistant, and have good water resistance.

[0003] During the production process, sandpaper needs to be dried by a drying device. The existing Chinese patent with publication number CN209541382U discloses a sandpaper processing drying box with thorough drying, comprising a box body, a support plate fixed to one side of the box body, a first support frame fixed to the upper end of the support plate, a first fixed frame provided on the other side of the box body, a second fixed frame fixed to the upper end of the first fixed frame, a second support frame fixed to the upper end of the second fixed frame, a conveying device provided in the first and second support frames and the box body, a first drying device provided at the upper end of the box body, a second drying device provided at the lower end of the box body, and the first and second drying devices corresponding to the conveying device, an L-shaped plate fixed to one end of the second fixed frame, and the lower end of the L-shaped plate fixed to one side of the upper end of the first fixed frame, a conveying channel fixed to the upper end of the second fixed frame, a collection box fixed to the upper end of the L-shaped plate, one end of the conveying channel connected to one end side wall of the collection box, and the first drying device and the conveying channel corresponding to each other.

[0004] The above-mentioned sandpaper processing drying box that dries thoroughly solves the problem of incomplete sandpaper drying through the cooperation between the hot air blower, the first air pipe, the second air pipe, the nozzle and the nozzle, realizes the function of drying the sandpaper multiple times, ensures the quality of the sandpaper, and saves costs. However, the above-mentioned sandpaper processing drying box that dries thoroughly still has some disadvantages, such as: the amount of sandpaper passing through is small, if the time passing through the drying box is short, the sandpaper drying effect is not good, if the time passing through the drying box becomes longer, the efficiency of sandpaper drying is affected, and needs to be improved. Summary of the Invention

[0005] The purpose of this application is to provide a sandpaper drying device to improve the drying efficiency of sandpaper.

[0006] The sandpaper drying equipment provided in the present application adopts the following technical solution: it includes a drying body, the drying body is connected to a feeding rod device, an upper rod device, a transport rod device and a lower rod device, the drying body is connected to a paper feeding device corresponding to the upper rod device, the feeding rod device is slidably connected to a plurality of support rods, and the plurality of support rods pass through the upper rod device, the transport rod device and the lower rod device in sequence.

[0007] By adopting the above technical solution, several support rods are placed on the feed rod device. The paper conveyor device transports the sandpaper into the drying body. The support rods suspend the sandpaper as they pass through the upper rod device. The support rods and the sandpaper suspended from them are then transferred to the feed rod device and moved along the feed rod device. This allows for a large number of suspended sandpaper, thereby improving sandpaper drying efficiency. After drying, the feed rod device removes the dried sandpaper from the drying body. The used support rods are then recycled through the lower rod device.

[0008] Optionally, the feeding rod device includes a carrier plate connected to the drying body and an inclined plate connected to the carrier plate, the inclined direction of the inclined plate is toward the upper rod device, the several support rods are placed on the inclined plate, and the upper rod device includes a first chain rotatably connected to the drying body and several first shifting rods fixedly connected to the first chain, and the first shifting rod can drive the support rod to disengage from the inclined plate.

[0009] By adopting the above technical solution, several support rods are placed on the inclined plate and rotated along the inclined direction of the inclined plate toward the upper rod device until the support rods move to the corresponding position. As the first chain moves, several first shifting rods move with the movement of the first chain. The first shifting rods abut the support rod closest to the first chain and drive the support rod away from the inclined plate, facilitating the transfer of the support rods.

[0010] Optionally, the transport rod device includes a second chain rotatably connected to the drying body and several second shift rods and a first limiting rod fixedly connected to the second chain, with a first limiting rod being located between two adjacent second shift rods, and the second shift rod being capable of driving the support rod to detach from the first chain.

[0011] By adopting the above technical solution, when the second chain moves, several second levers and the first limiting lever move along with the movement of the first chain. When the support rod on the first chain moves to the corresponding position, the second lever drives the corresponding support rod to separate from the first chain and be placed on the second chain. At this time, the support rod is located between the first limiting lever and the second lever, which limits the movement of the support rod, thereby improving the stability of the placement of the support rod.

[0012] Optionally, the carrier plate is connected to a limiting mechanism for limiting the movement of the support rod located on the carrier plate, the limiting mechanism includes a rotating rod rotatably connected to the carrier plate and a driving assembly for driving the rotating rod to rotate, the driving assembly is connected to the carrier plate, and the rotating rod is connected to a blocking rod for abutting against the support rod.

[0013] By adopting the above technical solution, when the support rod closest to the upper rod device moves to the corresponding position, the remaining support rods directly or indirectly abut against this support rod, causing the support rod closest to the upper rod device to be subjected to greater pressure, affecting the upper rod device from driving the support rod closest to the upper rod device to separate from the inclined plate. Therefore, a blocking rod is required to block some of the support rods. When the support rods are separated from the inclined plate, the drive assembly drives the rotating rod to rotate, separating the blocking rod from some of the support rods, allowing the blocked support rods to move toward the upper rod device. After some of the support rods pass the blocking rod, the drive assembly drives the rotating rod to return to its original position, and the blocking rod once again blocks the remaining support rods.

[0014] Optionally, the limiting mechanism also includes a partition rod connected to the rotating rod, the partition rod is used to separate two adjacent support rods, and the blocking rod is located between the partition rod and the drying body. When the blocking rod abuts against the support rod, the partition rod is separated from the support rod; when the partition rod abuts against the support rod, the blocking rod is separated from the support rod.

[0015] By adopting the above technical solution, when the support rod needs to be moved toward the upper rod device, the driving member is turned on, which drives the rotating rod to rotate, causing the blocking rod to move and separate from the support rod. As the blocking rod moves, the spacer rod also moves, and the spacer rod again abuts against the support rod, blocking the movement of the remaining support rods. The support rod located between the spacer rod and the blocking rod can be moved toward the upper rod device, thereby facilitating the control of the amount of movement of the support rod.

[0016] Optionally, the partition rod is detachably connected to the rotating rod, the carrier plate is connected to a support frame, the support frame is slidably connected to a push plate for driving the support rod to slide in a direction away from the blocking rod, the push plate corresponds to the partition rod, and the support frame is connected to a first driving member for driving the push plate to slide.

[0017] By adopting the above technical solution, the movable contact between the partition rod and the support rod will be damaged due to friction, so the partition rod needs to be replaced. When the machine stops running, when the partition rod is not in contact with the support rod, it is convenient to remove the partition rod; when the partition rod is in contact with the support rod, the support rod on the side of the partition rod away from the baffle rod directly or indirectly contacts the partition rod, and the support rod applies force to the partition rod, which makes it inconvenient to remove the partition rod from the rotating rod; even after removal, the support rod on the side of the partition rod away from the baffle rod is not blocked by any object, and all the support rods move toward the direction close to the upper rod device, thereby affecting the use of the equipment. Therefore, when the partition rod needs to be replaced, the first driving member drives the push plate to slide, and the push plate drives the support rod on the side of the partition rod away from the baffle rod to move in the direction away from the partition rod, providing space for the replacement of the partition rod, which can not only improve the efficiency of the replacement of the partition rod, but also prevent the support rod on the side of the partition rod away from the baffle rod from moving toward the direction close to the upper rod device.

[0018] Optionally, the push plate is connected to a guide block, and the support frame is provided with a guide groove for slidingly cooperating with the guide block, the guide groove includes a first groove and a second groove, the first groove and the second groove are connected, and the second groove is inclined away from the blocking rod.

[0019] By adopting the above technical solution, when the push plate slides, the guide block slides along the guide groove, and the sliding of the guide block and the guide groove cooperate to guide and limit the sliding of the push plate, thereby improving the stability of the sliding of the push plate. When the guide block enters the second groove, it is convenient for the push plate to drive the partition rod away from the support rod on the side of the barrier rod and move in the direction away from the partition rod, providing space for the replacement of the partition rod.

[0020] Optionally, the support frame is slidably connected to a accommodating plate, the first driving member is used to drive the accommodating plate to slide toward or away from the partition rod, the push plate is connected to a connecting block, the accommodating plate is provided with a sliding hole for slidingly cooperating with the connecting block, the connecting block is connected to a guide rod, and the accommodating plate is provided with a sliding channel for slidingly cooperating with the guide rod, and the sliding channel is connected to the sliding hole.

[0021] By adopting the above technical solution, when the guide block slides along the second groove away from the partition rod, the guide block drives the push plate to move in the direction away from the partition rod, and the push plate drives the guide rod to move in the direction away from the partition rod. The sliding of the guide rod cooperates with the sliding channel to guide and limit the sliding of the push plate, thereby improving the stability of the sliding of the push plate, thereby facilitating the push plate to move in the direction away from the partition rod.

[0022] Optionally, the driving assembly includes a cam rotatably connected to the carrier plate and a second driving member for driving the cam to rotate, the second driving member is connected to the carrier plate, and the cam is used to abut against the rotating rod.

[0023] By adopting the above technical solution, when the rotating rod needs to be rotated, the second driving member is opened, and the second driving member drives the cam to rotate around the axial center line of the output end of the second driving member. When the convex part of the cam is in contact with the rotating rod, the convex part of the cam drives the rotating rod to lift. When the convex part of the cam is separated from the rotating rod, the rotating rod is reset under the influence of gravity, thereby realizing the movement of the blocking rod and the partition rod.

[0024] Optionally, the driving assembly includes a connecting column rotatably connected to the carrier plate and a gear fixedly connected to the connecting column, the connecting column is connected to a passive rod for abutting against the first shift rod, the connecting column is connected to the carrier plate through a reset member, the carrier plate is slidably connected to a passive block for abutting against the rotating rod, the passive block is provided with a rack, and the rack is meshed with the gear.

[0025] By adopting the above technical solution, during the movement of the first chain, the first deflector rod abuts against the passive rod, and the first deflector rod drives the passive rod to rotate around the axis of the connecting column, that is, the gear rotates around the axis of the connecting column, the gear meshes with the rack and drives the passive block to move in the direction close to the rotating rod, the passive block abuts against the rotating rod and drives the rotating rod to rotate, that is, the blocking rod and the spacer rod move, and the spacer rod abuts against the support rod. When the first deflector rod is separated from the passive rod, the reset member drives the connecting column to reset, the connecting column drives the gear and the passive rod to reset, the gear drives the passive block to move in the direction away from the rotating rod, the passive block separates from the rotating rod, and the rotating rod resets under the influence of gravity, that is, the blocking rod and the spacer rod move, and the baffle plate abuts against the support rod again.

Each set of second driving sprockets 41 and second driven sprocket 42 is fitted with a second chain 43, and both the second driving sprockets 41 and second driven sprockets 42 engage with the second chain 43. The drying body 1 is fixedly connected to a fourth driving member 44 for driving the second driving sprockets 41 to rotate. The fourth driving member 44 is a motor, and the signal output end of the controller is connected to the signal input end of the fourth driving member 44. One side of one of the second driving sprockets 41 is fixedly connected to the output end of the fourth driving member 44. The second chain 43 is fixedly connected to a plurality of second shifting rods 431 and a plurality of first limiting rods 432. The plurality of second shifting rods 431 are evenly spaced along the length of the second chain 43, and the plurality of first limiting rods 432 are evenly distributed along the length of the second chain 43. There is a first limiting rod 432 between two adjacent second shifting rods 431, and there is a second shifting rod 431 between two adjacent first limiting rods 432. The length of the first limiting rod 432 is shorter than that of the second shifting rod 431, and adjacent second shifting rods 431 and first limiting rod 432 form a group. The distance between two adjacent second shifting rods 431 is shorter than the distance between two adjacent first shifting rods 331. The first chain 33 moves faster than the second chain 43.

[0048] The lower rod device 5 includes two third driving sprockets 51 and four third driven sprockets 52 that are rotatably connected within the drying body 1. The two third driving sprockets 51 are connected by a third connecting rod 511, the ends of which are fixedly connected to opposite sides of the two third driving sprockets 51. One third driving sprocket 51 and two third driven sprockets 52 form a set. Each set of third driving sprockets 51 and third driven sprockets 52 is fitted with a third chain 53. Both the third driving sprockets 51 and third driven sprockets 52 engage with the second chain 43. A fifth driving member 54 is fixedly connected to the drying body 1 for driving the third driving sprockets 51 to rotate. The fifth driving member 54 is a motor. The signal output of the controller is connected to the signal input of the fifth driving member 54. One side of one of the third driving sprockets 51 is fixedly connected to the output end of the fifth driving member 54. The third chain 53 is fixedly connected to a plurality of third shift rods 531 and a plurality of second limiting rods 532.

The length of the second limiting rod 532 is shorter than that of the third shift rod 531. An adjacent third shift rod 531 and a second limiting rod 532 form a group.

[0049] Combine Figure 3 and Figure 4As shown, the rod feeding device 2 includes two carrier plates 22 fixedly connected to the drying body 1. An inclined plate 23 is fixedly connected to opposing sides of each carrier plate 22, configured to flexibly abut against a support rod 21. The inclined plates 23 support both ends of the support rods 21. Several reinforcing rods 24 are connected between the two carrier plates 22, with their ends fixedly connected to opposing sides of the two carrier plates 22. The reinforcing rods 24 are fixedly connected to a first curved rod 25 and a second curved rod 26. The support rods 21 slide between the first curved rod 25 and the second curved rod 26, guiding and limiting the sliding of the support rods 21 and improving the stability of the sliding movement of the support rods 21. The second curved rod 26 extends from the end closest to the first chain 33 to the first chain 33. A gap exists between the end of the second curved rod 26 closest to the first chain 33 and the first chain 33, preventing the first chain 33 from abutting against the second curved rod 26 during movement. The distance between the end of the first curved rod 25 near the first chain 33 and the first chain 33 is greater than the distance between the end of the second curved rod 26 near the first chain 33 and the first chain 33. The distance between the end of the first curved rod 25 near the first chain 33 and the first chain 33 is sufficient to allow the support rod 21 to pass through. The two ends of the first curved rod 25 are connected by a guide rod 27. Both ends of the first curved rod 25 are fixedly connected to the guide rod 27. The guide rod 27 extends along its length away from the second curved rod 26. The end of the guide rod 27 away from the second curved rod 26 is bent toward the first chain 33 to form a guide portion 271.

[0050] Combine Figure 3 and Figure 4As shown, the carrier plate 22 is connected to a limiting mechanism 6 for limiting the sliding movement of the support rod 21 located between the first curved rod 25 and the second curved rod 26. The limiting mechanism 6 includes a rotating rod 61 rotatably connected to the carrier plate 22 and a driving assembly 62 for driving the rotating rod 61 to rotate. The rotating rod 61 is a U-shaped rod, with two pressure rods 611 fixedly connected to each end of the rotating rod 61. The two pressure rods 611 are arranged in parallel, with one pressure rod 611 located between the other pressure rod 611 and the first chain 33. The pressure rod 611 close to the first chain 33 is higher than the pressure rod 611 away from the first chain 33. The pressure rod 611 close to the first chain 33 is fixedly connected to a side of the pressure rod 611 close to the other pressure rod 611 for blocking the support rod 21. The blocking rod 63 is located at the end of the pressure rod 611 away from the rotating rod 61, and the distance between the blocking rod 63 and the two carrier plates 22 is the same. The pressure rod 611 away from the first chain 33 is detachably connected to a side close to another pressure rod 611 with a partition rod 64 for separating the support rod 21. The partition rod 64 is located at the end of the pressure rod 611 away from the rotating rod 61. The distance between the partition rod 64 and the two carrier plates 22 is the same, and at least one support rod 21 can be accommodated between the blocking rod 63 and the partition rod 64.

[0051] Combine Figure 3 and Figure 4 As shown, the driving assembly 62 includes a cam 621 rotatably connected to the carrier plate 22 and a second driving member 622 for driving the cam 621 to rotate. The second driving member 622 is a motor. The signal output end of the controller is connected to the signal input end of the second driving member 622. The cam 621 is used to movably abut against the rotating rod 61. The side of the cam 621 close to the second driving member 622 is fixedly connected to the output end of the second driving member 622.

[0052] The implementation principle of the sandpaper drying device in Example 1 of the present application is as follows:

[0053] A number of support rods 21 are placed between the first arc rod 25 and the second arc rod 26, and the support rods 21 are moved toward the direction close to the blocking rod 63. The second driving member 622 of the controller is opened, and the cam 621 rotates around the axis of the output end of the second driving member 622. When the convex part of the cam 621 is in contact with the rotating rod 61, the convex part of the cam 621 drives the rotating rod 61 to lift, and the partition rod 64 blocks the support rod 21 on the side of the partition rod 64 away from the blocking rod 63. When the convex part of the cam 621 is separated from the rotating rod 61, the rotating rod 61 is reset under the influence of gravity, and the partition rod 64 moves and no longer blocks the support rod 21; the blocking rod 63 moves, and the blocking rod 63 blocks the support rod 21. When the convex portion of the cam 621 is in contact with the rotating rod 61 again, the partition rod 64 blocks the support rod 21 on the side of the partition rod 64 away from the barrier rod 63, and the support rod 21 on the side of the partition rod 64 close to the barrier rod 63 is not blocked by the barrier rod 63 and moves toward the direction close to the first chain 33, so that the support rod 21 moves to the corresponding position.

[0054] The controller controls the third drive member 34, the fourth drive member 44, and the fifth drive member 54 to open. The third drive member 34 drives the two first driving sprockets 31 to rotate about their own axis. The first driving sprockets 31 drive the corresponding first chains 33 to move, and the first chains 33 drive the first driven sprocket 32 ​​to rotate. The first detent rod 331 moves with the rotation of the first chain 33. When the first detent rod 331 abuts the support rod 21, it drives the support rod 21 to move along the length of the guide rod 27. The guide rod 27 guides the movement of the support rod 21, preventing the support rod 21 from separating from the first detent rod 331 during movement. As the support rod 21 rises, the sandpaper hangs on it. When the support rod 21 moves to the desired position, it contacts the second lever 431, which drives the support rod 21 onto the second chain 43. At this point, the support rod 21 is positioned between the corresponding second lever 431 and the first limiting lever 432, limiting the movement of the support rod 21 and improving the stability of the support rod 21. This allows the sandpaper suspended from the support rod 21 to be spaced apart, improving the drying effect. As the second chain 43 moves, the support rod 21 moves toward the third chain 53, drying the sandpaper during this movement. The movement speed of the second chain 43 is slower than that of the first chain 33. When the second chain 43 reaches the desired position, the sandpaper is dried and is then transported out of the drying body 1 via the paper feed device. The third lever 531 abuts against the used support rod 21, and the third lever 531 drives the support rod 21 to fall onto the third chain 53. At this time, the support rod 21 is located between the corresponding third lever 531 and the second limiting lever 532, which limits the movement of the support rod 21 and improves the stability of the support rod 21. There is a rod collecting device at the pipe outlet, and the support rod 21 falls on the pipe collecting device to facilitate the collection of the support rod 21.

The passive block 628 defines a rack 6281, which meshes with the gear 624.

[0058] Combine Figure 6 、 Figure 7 and Figure 8 As shown, a guide block 612 is fixedly connected to one side of the rotating rod 61 close to the carrier plate 22, and a guide groove 222 for slidingly cooperating with the guide block 612 is recessed on one side of the carrier plate 22 close to the guide block 612 in a direction away from the guide block 612. The guide block 612 and the carrier plate 22 are connected by an elastic member 613, and the elastic member 613 is a spring. One end of the elastic member 613 is fixedly connected to the guide block 612, and the other end is fixedly connected to an inner wall of one side of the guide groove 222.

[0059] Combine Figure 9 and Figure 10 As shown, the end of the spacer rod 64 away from the corresponding pressure rod 611 is provided with a guide surface 641 for movable contact with the support rod 21. The end of the spacer rod 64 close to the pressure rod 611 is connected to a threaded section (not shown in the drawings), and the pressure rod 611 is recessed to form a threaded groove 6111 for threaded engagement with the spacer rod 64.

[0060] Combine Figure 10 and Figure 11 As shown, the first arc rod 25 is fixedly connected to the support frame 7, and the support frame 7 is slidably connected to the accommodating plate 71. The side of the support frame 7 away from the partition rod 64 is fixedly connected to the first driving member 72 for driving the accommodating plate 71 to slide toward or away from the partition rod 64. The first driving member 72 is a cylinder, and the signal output end of the controller is connected to the signal input end of the first driving member 72. The output end of the first driving member 72 passes through the support frame 7, and the side of the accommodating plate 71 close to the first driving member 72 is fixedly connected to the output end of the first driving member 72.

[0061] Combine Figure 10 、 Figure 11 、 Figure 12 and Figure 13As shown, two push plates 8 are slidably connected to the side of the receiving plate 71 away from the first driving member 72, and are used to correspond to the partition rod 64. The partition rod 64 is located between the two push plates 8. The push plate 8 is used to drive the support rod 21 to move away from the blocking rod 63. The end of the push plate 8 away from the receiving plate 71 is provided with a tip 85, which facilitates separating the two adjacent support rods 21. A guide block 81 is fixedly connected to the side of the push plate 8 away from the other push plate 8. The support frame 7 defines a guide slot 73 for slidably engaging with the guide block 81. The guide slot 73 includes a first slot 731 and a second slot 732. The first slot 731 and the second slot 732 are connected, and the second slot 732 extends obliquely in the direction away from the partition rod 64.

[0062] Combine Figure 11 、 Figure 12 and Figure 13 As shown, a connecting block 82 is fixedly connected to the side of the push plate 8 near the receiving plate 71. A sliding hole 711 is recessed in the receiving plate 71 for slidingly engaging with the connecting block 82. A guide rod 83 is fixedly connected to the end of the connecting block 82 away from the push plate 8. A turntable 84 is rotatably connected to both ends of the guide rod 83. The receiving plate 71 defines a sliding channel 712 for slidingly engaging with the turntable 84. The sliding channel 712 is connected to the sliding hole 711. When the push plate 8 slides, the outer peripheral surface of the turntable 84 movably abuts against the inner wall of the sliding channel 712, reducing friction and facilitating movement of the push plate 8.

[0063] The implementation principle of a sandpaper drying device in Example 2 of the present application is as follows:

[0064] When the first chain 33 moves, the first deflector 331 abuts the passive rod 627, which drives the passive rod 627 to rotate about the axis of the connecting column 623. That is, the gear 624 rotates about the axis of the connecting column 623. The gear 624 meshes with the rack 6281 and drives the passive block 628 to move toward the rotating rod 61. The passive block 628 abuts the rotating rod 61 and drives the rotating rod 61 to rotate. That is, the blocking rod 63 and the spacer 64 move, and the elastic member 613 is elastically deformed and stretched under tension. The spacer 64 abuts the support rod 21, blocking the movement of the support rod 21, and the blocking rod 63 separates from the support rod 21. When the first deflector rod 331 is separated from the passive rod 627, the reset member 626 drives the connecting rod 623 to reset, the connecting rod 623 drives the gear 624 and the passive rod 627 to reset, the gear 624 drives the passive block 628 to move away from the rotating rod 61, the elastic member 613 elastically resets, and the elastic member 613 drives the rotating rod 61 to reset, the spacer rod 64 separates from the support rod 21, and the blocking rod 63 abuts the support rod 21, thereby blocking the movement of the support rod 21. When each first deflector rod 331 abuts the passive rod 627, the rotating rod 61 will rotate.

[0065] When the partition rod 64 needs to be disassembled, the controller controls the first driving member 72 to open, and the first driving member 72 drives the accommodating plate 71 to move toward the direction close to the support rod 21, so that the push plate 8 abuts against the corresponding support rod 21, and the push plate 8 separates the support rods 21 on both sides of the partition rod 64, and the guide block 81 slides along the first groove 731. When the guide block 81 disengages from the first groove 731 and enters the second groove 732, the push plate 8 drives the push plate 8 to move away from the support rod 21 on the side of the baffle rod 63 in the direction away from the baffle rod 63, that is, the turntable 84 slides along the sliding channel 712 to provide space for the disassembly of the partition rod 64.

[0066] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
