Description

Technical Field

[0001] The invention belongs to the technical field of dry wall screw processing, in particular to a drying device before heat treatment of dry wall screws. Background Art

[0002] At present, drywall screws need to be heat treated after processing and forming to enhance the strength of the drywall screws. Most of the existing drywall screws are stored in boxes before heat treatment. Affected by the environment, the drywall screws in the boxes are prone to moisture, which is not conducive to subsequent heat treatment. Therefore, the damp drywall screws need to be dried.

[0003] In the prior art, the drying process for damp drywall screws is mostly to place a batch of drywall screws in an oven, and then supply hot air into the oven to dry the drywall screws with the hot air. However, when the drywall screws are placed in the oven in batches, the drywall screws are usually piled up. When the hot air is supplied into the oven, only the surface drywall screws can be dried, while the drywall screws in the inner layer are difficult to be dried quickly, resulting in a poor drying effect of the drywall screws. Summary of the invention

[0004] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by the embodiments of the present invention is to provide a drying device before heat treatment of drywall screws.

[0010] The paving assembly is arranged on one side of the transfer plate and is used to spread the drywall nails accumulated on the bottom of the inner side of the drying drum.

[0011] The driving assembly is arranged inside the drying drum. When two adjacent groups of transfer plates rotate to an upward position, the driving assembly is used to drive the sealing plate between the two groups of transfer plates to rotate toward the inside of the rotating drum, thereby opening the corresponding collecting port.

[0012] As a further improvement of the present invention: the paving assembly includes an electromagnetic adsorption plate, a conductive core and an arc-shaped conductive block.

[0013] The electromagnetic adsorption plates are provided in a plurality of groups, and the plurality of electromagnetic adsorption plates are arranged vertically and spaced apart on one side of the transfer plate.

[0014] The conductive cores are provided in a plurality of groups, and the conductive cores correspond to the electromagnetic adsorption plates one by one. One end of each group of conductive cores is connected to a group of electromagnetic adsorption plates, and the other end of each group of conductive cores is attached to the inner wall of the drying drum.

[0015] The arc-shaped conductive blocks are provided in several groups, several of which are embedded in the end surface of one end of the drying cylinder, several of which correspond to several of the conductive cores one by one, several of which are arranged on the rotation paths of several of the conductive cores and maintain an inclined and staggered distribution, and several of which are connected to an external power supply through wires.

[0016] As a further improvement of the present invention: the inner wall of the drying cylinder is provided with a groove.

[0017] The driving assembly includes an L-shaped rod, a blocking piece and a second elastic member.

[0018] One end of the baffle is hingedly connected to the inner wall of the groove, and the other end extends to the outside of the groove. The baffle is inclined. The second elastic member is arranged inside the groove to provide elastic support for the baffle. One end of the L-shaped rod is connected to the outer wall of the sealing plate, and the other end is attached to the inner wall of the drying cylinder.

[0019] The outer wall of the sealing plate is also connected to the transfer plate via a first elastic member, and the first elastic member is used to provide elastic tension to the sealing plate.

[0020] As a further improvement of the present invention: the first elastic member and the second elastic member are springs or metal springs.

[0021] As a further improvement of the present invention: a discharge port is provided at one end of the drying cylinder, and an opening communicating with the discharge port is provided at one end of the rotating cylinder away from the motor.

[0022] A material guide assembly is arranged inside the rotating drum, and the material guide assembly is used to guide the dry wall nails inside the rotating drum to the outside of the drying drum through the opening and the discharge port.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] In the embodiment of the present invention, when the drywall nails need to be dried, the drywall nails can be put into the drying drum from the feeding port. After entering the drying drum, the drywall nails act between two adjacent groups of transfer plates in turn, and the motor drives the rotating drum to rotate, thereby driving a plurality of transfer plates to rotate. When the plurality of transfer plates rotate, the drywall nails between the two adjacent groups of transfer plates are transferred to the bottom inside the drying drum in turn, and then heated by the electric heating plate to achieve the drying of the drywall nails. The dried drywall nails continue to rotate with the transfer plate, and the transfer plate can push the drywall nails to rotate upward along the inside of the drying drum. When two adjacent groups of transfer plates rotate to the upward position, the driving component drives the sealing between the two groups of transfer plates. The plate rotates toward the inside of the drum, thereby opening the corresponding collecting port. At this time, the dried drywall nails located between the two groups of transfer plates automatically enter the inside of the drum through the opened collecting port under the action of gravity, thereby realizing the automatic collection of the dried drywall nails. When the drywall nails are transferred to the bottom of the inner side of the drying drum, the drywall nails are usually piled up.

DETAILED DESCRIPTION

[0035] The technical solution of the present invention is further described in detail below in conjunction with specific implementation methods.

[0036] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0037] See also Figure 1 , Figure 2 as well as Figure 3The present embodiment provides a pre-drying device for heat treatment of drywall nails, including a drying cylinder 10, an electric heating plate 20, a motor 30, a rotating drum 40, a paving assembly 50 and a driving assembly 60. The side wall of the drying cylinder 10 is provided with a feeding port 101, the electric heating plate 20 is embedded in the bottom of the drying cylinder 10, the rotating drum 40 is arranged inside the drying cylinder 10 and distributed along the axial direction of the drying cylinder 10, the side wall of the rotating drum 40 is fixedly provided with a plurality of transfer plates 402 distributed at intervals, the side wall of the rotating drum 40 is provided with a plurality of collecting ports, the plurality of collecting ports and the plurality of transfer plates 402 are alternately distributed, and a sealing plate 401 is hingedly provided in each group of the collecting ports, the motor 3 0 is fixedly mounted on one end of the outside of the drying cylinder 10, and is used to drive the rotating drum 40 and the plurality of transfer plates 402 to rotate. When the plurality of transfer plates 402 rotate, the drywall screws are driven to rotate along the inside of the drying cylinder 10. The spreading assembly 50 is arranged on one side of the transfer plate 402, and is used to spread the drywall screws accumulated on the bottom of the inner side of the drying cylinder 10. The driving assembly 60 is arranged inside the drying cylinder 10. When two adjacent groups of transfer plates 402 rotate to an upward position, the driving assembly 60 is used to drive the sealing plate 401 between the two groups of transfer plates 402 to rotate toward the inside of the rotating drum 40, thereby opening the corresponding collecting port.

[0038] When the drywall nails need to be dried, the drywall nails can be put into the drying drum 10 from the feeding port 101. After entering the drying drum 10, the drywall nails act between two adjacent groups of transfer plates 402 in turn, and the motor 30 drives the rotating drum 40 to rotate, thereby driving the transfer plates 402 to rotate. When the transfer plates 402 rotate, the drywall nails located between the two adjacent groups of transfer plates 402 are transferred to the bottom of the inner side of the drying drum 10 in turn, and then heated by the electric heating plate 20 to achieve the drying of the drywall nails. After the drywall nails are dried, as the transfer plates 402 continue to rotate, the transfer plates 402 can push the drywall nails to rotate upward along the inside of the drying drum 10. When two adjacent groups of transfer plates 402 rotate to the upward position, the driving assembly 60 drives the sealing plate 401 between the two groups of transfer plates 402 to rotate toward the inside of the rotating drum 40, thereby opening the corresponding collecting port. At this time, the dried drywall nails located between the two groups of transfer plates 402 automatically enter the inside of the rotating drum 40 through the opened collecting port under the action of gravity, thereby realizing the automatic collection of the dried drywall nails; when the drywall nails are transferred to the bottom of the inner side of the drying drum 10, the drywall nails are usually in a stacked state. At this time, the spreading assembly 50 is used to spread the stacked drywall nails, so that the drywall nails can be evenly heated, thereby improving the drying effect of the drywall nails.

[0039] See also Figure 1 , Figure 3 as well as Figure 5In one embodiment, the paving assembly 50 includes an electromagnetic adsorption plate 501, a conductive core 502 and an arc-shaped conductive block 503. The electromagnetic adsorption plate 501 is provided in a plurality of groups, and the plurality of electromagnetic adsorption plates 501 are arranged vertically at intervals on one side of the transfer plate 402. The conductive core 502 is provided in a plurality of groups, and the plurality of conductive cores 502 correspond to the plurality of electromagnetic adsorption plates 501 one by one. One end of each group of the conductive cores 502 is connected to a group of the electromagnetic adsorption plates 501, and each group of the conductive cores 502 is connected to a group of the electromagnetic adsorption plates 501. 02 The other end is in contact with the inner wall of the drying cylinder 10, and the arc-shaped conductive blocks 503 are provided in a plurality of groups. A plurality of the arc-shaped conductive blocks 503 are embedded in the end surface of one end of the drying cylinder 10, and a plurality of the arc-shaped conductive blocks 503 correspond to a plurality of the conductive cores 502 one by one. A plurality of the arc-shaped conductive blocks 503 are arranged on the rotation path of a plurality of the conductive cores 502 and maintain an inclined and staggered distribution, and a plurality of the arc-shaped conductive blocks 503 are connected to an external power supply (not shown in the figure) through a wire (not shown in the figure).

[0040] When the drywall nails between two adjacent groups of transfer plates 402 are transferred to the bottom of the inner side of the drying drum 10 and are in a stacked state, the electromagnetic adsorption plates 501 on one side of one group of transfer plates 402 in the two adjacent groups of transfer plates 402 face the stacked drywall nails. At this time, the top group of conductive cores 502 are in contact with the top group of arc-shaped conductive blocks 503. The external power supply supplies power to the top electromagnetic adsorption plate 501 through the wire, the top conductive core 502 and the top arc-shaped conductive block 503. The top electromagnetic adsorption plate 501 generates magnetic attraction, which attracts the upper drywall nails in the stacked state, causing the upper drywall nails to move laterally compared to the lower drywall nails. After the block 503 is detached, the next upper group of conductive cores 502 contacts the next upper group of arc-shaped conductive blocks 503, and the external power supply supplies power to the next upper electromagnetic adsorption plate 501 through the wire, the next upper conductive core 502 and the next upper arc-shaped conductive block 503. The next upper electromagnetic adsorption plate 501 generates magnetic attraction, which then attracts the upper drywall screws again, causing the upper drywall screws to move laterally compared to the lower drywall screws again... This cycle repeats itself, and when the bottom group of conductive cores 502 contacts the bottom group of arc-shaped conductive blocks 503, the drywall screws that were originally in a stacked state are reduced layer by layer, and finally spread on the inner bottom of the drying cylinder 10 and maintain a relatively thin thickness, thereby obtaining uniform heating and drying.

[0041] See also Figure 3 as well as Figure 6In one embodiment, a groove 104 is provided on the inner wall of the drying cylinder 10, and the driving assembly 60 includes an L-shaped rod 601, a baffle 602 and a second elastic member 603. One end of the baffle 602 is hingedly connected to the inner wall of the groove 104, and the other end extends to the outside of the groove 104. The baffle 602 is inclinedly distributed. The second elastic member 603 is arranged inside the groove 104 to provide elastic support for the baffle 602. One end of the L-shaped rod 601 is connected to the outer wall of the sealing plate 401, and the other end is in contact with the inner wall of the drying cylinder 10. The outer wall of the sealing plate 401 is also connected to the transfer plate 402 through the first elastic member 403. The first elastic member 403 is used to provide elastic tension to the sealing plate 401.

[0042] When two adjacent groups of transfer plates 402 rotate to the upward position, the dried drywall nails between the two groups of transfer plates 402 fall to the outside of the corresponding sealing plate 401 due to gravity. As the rotating drum 40 continues to rotate, the L-shaped rod 601 on the outer wall of the sealing plate 401 acts on the bottom of the baffle 602. Since the baffle 602 is inclined, the baffle 602 can push the L-shaped rod 601 and then drive the sealing plate 401 to rotate toward the inside of the rotating drum 40, so that the corresponding collecting port is opened, and the dried drywall nails located outside the sealing plate 401 fall into the inside of the rotating drum 40 through the opened collecting port, thereby realizing the automatic collection and storage of the dried drywall nails. After the drywall nails are collected in the inside of the rotating drum 40, the L-shaped rod 601 can be moved from the baffle 602. When the bottom passes, the first elastic member 403 can pull the corresponding sealing plate 401 to make the sealing plate 401 rotate in the opposite direction, thereby reclosing inside the collecting port to prevent the drywall nails inside the rotating drum 40 from leaking; because one end of the baffle 602 is hingedly connected to the inner wall of the groove 104, and the other end extends to the outside of the groove 104, the baffle 602 is bound to occupy the inner space of the drying drum 10. When the rotating drum 40 drives a plurality of transfer plates 402 to rotate, the end of the transfer plate 402 can act on the baffle 602 and then drive the baffle 602 to rotate into the groove 104 and retract into the groove 104, so that the baffle 602 will not interfere with the rotation of the transfer plate 402, thereby ensuring that the transfer plate 402 can rotate smoothly inside the drying drum 10.

[0043] In one embodiment, the first elastic member 403 and the second elastic member 603 may be springs or metal springs, which are not limited herein.

[0044] See also Figure 2In one embodiment, a discharge port 103 is provided at one end of the drying cylinder 10, an end of the rotating drum 40 away from the motor 30 is provided with an opening connected to the discharge port 103, and a material guide component 70 is provided inside the rotating drum 40. The material guide component 70 is used to guide the drywall nails inside the rotating drum 40 to the outside of the drying cylinder 10 through the opening and the discharge port 103, so as to realize automatic discharge of the drywall nails after drying.

[0045] See also Figure 2 as well as Figure 4 In one embodiment, the material guide assembly 70 includes a material guide shaft 701 and a fixed plate 702, one end of the material guide shaft 701 extends to the outside of the drying cylinder 10 and is fixedly connected to the outer wall of the drying cylinder 10 through the fixed plate 702, and the other end extends to the interior of the rotating drum 40 through the discharge port 103 and the opening, and a material guide slope is provided on the upper part of the material guide shaft 701.

[0046] When the dried drywall nails enter the inside of the rotating drum 40 through the opened collecting port, the drywall nails can automatically slide down along the guiding slope on the upper part of the guiding shaft 701, and finally be discharged to the outside of the drying drum 10 through the opening at one end of the rotating drum 40 and the discharging port 103, thereby realizing the automatic discharging of the dried drywall nails.

[0047] See also Figure 1 In one embodiment, a support plate 102 is fixedly provided on the bottom edge of the drying cylinder 10 .

[0048] In the embodiment of the present invention, when it is necessary to dry the drywall nails, the drywall nails can be put into the drying drum 10 from the feeding port 101. After entering the drying drum 10, the drywall nails act between two adjacent groups of transfer plates 402 in turn, and the motor 30 drives the rotating drum 40 to rotate, thereby driving the plurality of transfer plates 402 to rotate. When the plurality of transfer plates 402 rotate, the drywall nails located between two adjacent groups of transfer plates 402 are transferred to the bottom of the inner side of the drying drum 10 in turn, and then heated by the electric heating plate 20 to achieve the drying of the drywall nails. After drying, the drywall nails continue to rotate with the transfer plates 402, and the transfer plates 402 can push the drywall nails to rotate upward along the inside of the drying drum 10. When two adjacent groups of transfer plates 402 rotate to the upward position, the driving component 60 drives The sealing plate 401 between the two groups of transfer plates 402 rotates toward the inside of the rotating drum 40, thereby opening the corresponding collecting port. At this time, the dried drywall nails located between the two groups of transfer plates 402 automatically enter the inside of the rotating drum 40 through the opened collecting port under the action of gravity, thereby realizing the automatic collection of the dried drywall nails. When the drywall nails are transferred to the bottom of the inner side of the drying drum 10, the drywall nails are usually in a piled state. At this time, the spreading assembly 50 is used to spread the piled drywall nails, so that the drywall nails can be evenly heated, thereby improving the drying effect of the drywall nails. Compared with the prior art, the automatic and uniform drying of the drywall nails can be realized, and the dried drywall nails can be automatically collected, which has the advantages of good drywall nail drying effect and high drying efficiency.

[0049] The preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention.
