Description

Technical Field

[0001] The present application relates to the field of textile production, and in particular to a drying device. Background Art

[0002] At present, in the production process of carpets, especially tufted low-sugar, it is generally necessary to go through processes such as dyeing tufted yarn, tufting, inspection and darning, gluing (composite base cloth), drying, shearing, etc., and finally form a finished product. During tufting, the tufting needle with tufted yarn is inserted into the base cloth through the tufting machine to form a tufting array with uniform spacing. At this time, the tufting is easier to fall off on the base cloth, so it is necessary to fix it on the reverse side with glue or other adhesives. This process is traditionally called back glue process, and the glue is dried.

[0003] In the prior art, after tufting is completed, it is necessary to apply glue manually, or transfer the carpet from the tufting machine to the placement plane of the dryer for glue coating, and then dry it. Most dryers include a conveyor belt and a drying box. The carpet is laid flat on the conveyor belt, and after the glue is coated, it is transported by the conveyor belt to the drying box for drying.

[0004] Regarding the above-mentioned related technologies, since some carpets are large in area, with length and width both greater than 4 meters, in order to be able to spread the carpets flat for glue coating and drying, the conveyor belt needs to have sufficient support area, so the structure of the conveyor belt needs to be designed to be relatively large to meet the normal support and transportation of the carpets. When the next carpet is continued to be dried after the drying is completed, some carpets need to be cooled at room temperature for a period of time before entering the next process; in order to ensure production efficiency, the previous carpet is transported out of the drying box after the next carpet is transported to the drying box. Therefore, the end of the conveyor belt after it comes out of the drying box also needs a sufficiently large support area, resulting in the conveyor belt being located in the part covered by the drying box and the parts on both sides of the drying box. The structure is relatively large, which is not convenient for the production and assembly of the conveyor belt, and inconvenient for maintenance. Summary of the invention

[0005] In order to facilitate the production, assembly and maintenance of a drying device, the present application provides a drying device.

[0006] The present application provides a drying device that adopts the following technical solution:

[0007] A drying device comprises a support portion, wherein a support surface is arranged at the upper end of the support portion; a drying box, wherein the drying box spans two opposite sides of the support portion, a gap is provided between the drying box and the support surface, the drying box is slidably connected to the support portion, and the drying box slides in a horizontal direction and in a direction that sweeps across and covers the top of the support portion; and a driving member, wherein the driving member is used to drive the drying box to move.

[0008] By adopting the above technical solution, the carpet to be coated with glue can be laid on the support part, and then the drying box can be moved by the driving part to move the drying box above the carpet to be dried, so as to dry the carpet; there is no need to use a conveyor belt with a larger structure, which changes the traditional method of moving the carpet with a conveyor belt. The drying box can be directly set to be movable, and then a support part can be selected, and the support part can be selected as the ground, so it is only necessary to slide a drying box directly on the ground, which is convenient and quick, and realizes the effect of facilitating the production, assembly and maintenance of the drying device.

[0009] Preferably, the drying box includes a cover body, a plurality of cross bars arranged in the cover body, and drying lamps installed at intervals on the cross bars, the cross bars are arranged at intervals in the cover body, the opening of the cover body is downward and toward the support part, and the two ends of the cover body are slidably connected to the opposite sides of the support part.

[0010] By adopting the above technical solution, the cross bar can facilitate the installation of the drying lamp. When the drying lamp is turned on, it can emit ultraviolet light and have a certain amount of heat to dry the glue; the cover can cover the outside of all the drying lamps to collect heat, reduce heat loss to the surroundings, ensure drying efficiency, and reduce the impact of heat on the surrounding working environment.

[0011] Preferably, the cross bar is connected to opposite sides of the cover body, and the cross bar is slidably adjusted along the horizontal direction, and the sliding direction of the cross bar is perpendicular to the sliding direction of the cover body.

[0012] By adopting the above technical solution, since some carpets can withstand higher temperatures for drying, while some carpets cannot withstand higher temperatures for drying; the distance between two adjacent cross bars in the cover can be adjusted by sliding the position of the cross bar, thereby adjusting the arrangement density of the drying lamps; therefore, drying lamps with different arrangement densities can be adjusted according to different products to improve applicability.

[0013] Preferably, the horizontal cross-section of the cover body is rectangular, and the first slide rails are provided on the opposite sides where the cover body is connected to the two ends of the cross bar. A first slider slidably connected to the first slide rail is fixed on the cross bar, and one end of the cross bar extends out of the cover body. An external threaded portion is provided at the end of the cross bar extending out of the cover body, and a tightening piece is screwed on the external threaded portion. One end of the tightening piece is tightened against the outside of the cover body, and a clearance hole parallel to the first slide rail is provided on the outside of the cover body. The external threaded portion passes through the clearance hole and slides along the length direction of the clearance hole.

[0014] By adopting the above technical solution, the smooth sliding of the cross bar can be achieved through the cooperation between the first slider and the second slide rail; a clearance hole is provided so that one end of the cross bar can extend out of the cover body to facilitate the movement of the cross bar. After adjusting the position of the cross bar, the fastening piece can be rotated so that the fastening piece is pressed against the outside of the cover body to fix the position of the cross bar.

[0015] Preferably, a partition plate that can be adjusted by sliding along the height direction is provided on the cover body. When the partition plate slides, it enters into or slides out of the cover body, and the partition plate is parallel to the length direction of the cross bar; when the partition plate moves downward to the lowest position, the lower end of the partition plate is spaced from the supporting surface, and a through hole is provided at the upper end of the cover body for the partition plate to enter the cover body.

[0016] By adopting the above technical solution, the through hole can ensure entry into or exit from the cover. Since the internal cavity of the entire cover is large, when the low-sugar area to be dried is small, the cover can be entered through the sliding partition, thereby dividing the interior of the cover into cavities of different sizes, which can reduce the situation where heat is excessively dispersed inside the cover; and some drying lamps that are far away from the carpet can be turned off, so that the heat can be concentrated in the cavity opposite to the upper and lower parts of the carpet, thereby improving the heating and drying efficiency and saving power.

[0017] Preferably, the through holes are arranged at intervals along the direction of the parallel cross bars, and a second slide rail is provided on the cover body near the two ends of the cross bars, and a second slider is slidably connected to the second slide rail, and a gantry frame with an opening facing downward is slidably connected to the outer side of the upper end of the cover body, and the lower sides of the two ends of the gantry frame are respectively fixed to the second sliders on different second slide rails; the two ends of the partition plate are slidably connected to the opposite sides of the gantry frame, and a screw is vertically screwed on the upper end of the gantry frame, and the lower end of the screw is rotatably connected to the upper end of the partition plate, and the position between the screw and the partition plate is relatively stationary.

[0018] By adopting the above technical solution, through the cooperation between the second slide rail and the second slider, the gantry frame can be slid on the cover body, and the gantry frame and the partition plate can be moved to the required position relative to the through hole; then, by turning the screw, the partition plate can be moved up and down on the gantry frame, so that the partition plate enters or leaves the cover body from the through hole.

[0019] Preferably, the cover body includes a side frame, a top frame, a side plate and a top plate. The side frame is a rectangular frame with openings at both ends. The top frame is fixed to the upper opening of the side frame. The side plate is fixed to the peripheral side of the side frame. The top plate is fixed to the top frame. Cover plates are rotatably provided on both ends of the top plate near the sliding side of the cross bar.

[0020] By adopting the above technical solution and providing the side frames and the top frame, it is convenient to install and fix the side panels and the top panel composed of several sheets of plate materials, and at the same time the structural strength of the cover body can be ensured.

[0021] Preferably, an exhaust fan is installed on the outer side of the cover body, the air suction port of the exhaust fan is connected to the inside of the cover body, and the air outlet of the exhaust fan is connected to an exhaust pipe.

[0022] By adopting the above technical solution, since the glue has a certain odor when drying, the cover body can reduce the spread of the odor, and the exhaust fan can extract the odor in the cover body through the exhaust pipe.

[0023] Preferably, a collecting pipe is provided at the end of the exhaust pipe away from the exhaust fan. The collecting pipe is arranged along the sliding direction of the cover body. A strip hole is provided on the horizontal side of the collecting pipe. The end of the exhaust pipe away from the exhaust fan extends into the strip hole. A plurality of flexible curtain strips covering the strip holes are fixed at the upper end of the collecting pipe. When the cover body slides, one end of the exhaust pipe slides along the strip hole.

[0024] By adopting the above technical solution, the end of the exhaust pipe away from the exhaust fan can enter the collecting pipe from the strip hole, and the flexible curtain strip can cover the strip hole, playing a certain role in sealing the strip hole; because the exhaust pipe will move a certain distance with the cover body, and the collecting pipe is stationary, the movement of the exhaust pipe will drive the flexible curtain strip to shake and bend, thereby ensuring the normal movement of the exhaust pipe; when the exhaust pipe slides through the flexible curtain strip, the flexible curtain strip will continue to return to the initial position covering the strip hole, so that the odor is not easy to dissipate from the strip hole, and the normal movement of the exhaust pipe can be ensured.

[0025] Preferably, the upper edge and lower edge of the collecting tube on both sides of the strip hole are staggered in the vertical plane, the upper end of the flexible curtain strip is fixed to the inner side of the upper edge, the lower end of the flexible curtain strip is located in the collecting tube and the outer side of the flexible curtain strip abuts against the inner side of the lower edge, and a counterweight block is provided at the lower end of the flexible curtain strip.

[0026] By adopting the above technical scheme, the counterweight block enables the flexible curtain strip to be reset faster; by being staggered on the upper and lower sides of the strip hole, the upper end of the flexible curtain strip is fixed on the inner side of the collecting tube, and the lower end of the flexible curtain strip is located inside the collecting tube and the outer side overlaps the inner side of the lower edge, so that the flexible curtain strip can better seal the strip hole after shaking and bending, thereby reducing the emission of odor from the collecting tube.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] (1) By setting the coordination between the support part, the drying box and the driving part, the driving part drives the drying box to slide, no conveyor belt is required, only one drying box is needed, and the support part can be directly selected as a flat ground, so that the drying device can be easily produced, assembled and maintained;

[0029] (2) By setting a sliding adjustment crossbar, the arrangement density of the drying lamps can be adjusted, thereby adjusting the local heating and drying temperature inside the hood to improve applicability;

[0030] (3) By providing a partition plate, the cavity in the cover can be divided as needed to separate cavities of different sizes. The space above and below the carpet in the cover can be divided into smaller spaces, so that the heat is more concentrated and power can be saved. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0036] The following is combined with Figure 1-4 This application is described in further detail.

[0037] The present application discloses a drying device, which is mainly suitable for drying the adhesive backing of a large carpet. Figure 1 The drying device includes a support part 1, a drying box 2 and a driving member 3. The upper end of the support part 1 is provided with a horizontal supporting surface 4. The support part 1 can directly select the indoor floor; in this embodiment, the support part 1 is rectangular and selects the existing indoor floor, and the carpet is laid on the supporting surface 4. The drying box 2 spans the opposite sides of the long side of the support part 1, and there is a gap between the lower end of the drying box 2 and the supporting surface 4. The end of the drying box 2 is slidably connected to the two long sides of the support part 1, and the drying box 2 reciprocates along the horizontal length direction of the support part 1; the driving member 3 is installed on the drying box 2 and is used to drive the drying box 2 to move. When the drying box 2 slides, the drying box 2 sweeps and covers the upper part of the support part 1.

[0038] The carpet is laid on the support part 1, and then glue is applied, and then the drying box 2 is moved to a position covering the carpet; after drying, the drying box 2 is moved to the top of the next carpet to be dried, and the dried carpet can be cooled at room temperature. Therefore, there is no need to use a conveyor belt with a large structure volume, and only the movable drying box 2 needs to be installed on the support part 1, so that the drying device can be easily produced, assembled, and maintained.

[0039] Guide rails 5 are fixed on the two opposite long sides of the support part 1, and rollers 6 are rotatably connected to the lower sides of the two ends of the drying box 2 in the length direction, and the rollers 6 are rollingly connected to the guide rails 5; the driving member 3 includes a driving motor installed on the drying box 2, the driving motor is transmission-connected to the rollers 6, and the driving motor drives the rollers 6 to roll on the slide rails.

[0040] Specifically, refer to Figure 1 and Figure 2 The drying box 2 includes a cover body 201, a plurality of cross bars 202 arranged in the cover body 201, and drying lamps 203 installed at intervals on the cross bars 202. The opening of the cover body 201 is downward and toward the support part 1. The water cross section of the cover body 201 is rectangular. The rollers 6 are slidably connected to the two ends of the length direction of the cover body 201, and the two ends of the cover body 201 are slidably connected to the support part 1. The cross bars 202 are arranged along the width direction of the cover body 201, and the cross bars 202 are arranged in the cover body 201 at intervals along the length direction of the cover body 201. The drying lamp 203 can select an existing ultraviolet lamp for drying glue, irradiate the carpet below, and generate higher heat to dry the glue. The cover body 201 can cover the outside of all drying lamps 203 to reduce the spillover of heat.

[0041] Reference Figure 1 and Figure 3 The cover body 201 includes a side frame 211, a top frame 212, a side plate 213 and a top plate 214. The side frame 211 is a rectangular frame with openings at both ends. The horizontal cross section of the side frame 211 is rectangular. The top frame 212 and the upper opening of the side frame 211 are mutually adapted and fixed to the upper end of the side frame 211. The side plate 213 is fixed to the outer peripheral side of the side frame 211. The top plate 214 is fixed to the upper surface of the top frame 212 to close the peripheral side and the upper end of the cover body 201. The side frame 211 and the top frame 212 can ensure the structural strength of the cover body 201, and at the same time facilitate the fixed installation of multiple small-area plates that constitute the side plates 213 and the top plate 214. Among them, the top plate 214 is rotatably connected to the two ends of the long side of the support part 1 with a cover plate 7, which is convenient for opening the inside of the cover body 201.

[0042] Since different carpets can withstand different drying temperatures and the positions of carpets are also different, in order to facilitate the adjustment of the arrangement density of the drying lamps 203, the drying temperature is adjusted to improve applicability. The crossbar 202 is slidably adjusted along the length direction of the cover body 201, and the sliding direction of the crossbar 202 is perpendicular to the sliding direction of the cover body 201. By adjusting the distance between two adjacent crossbars 202, the arrangement density of the drying lamps 203 can be adjusted, and the drying lamps 203 can also be concentrated together for drying. Moreover, the crossbar 202 can be moved to a position close to the cover plate 7 to facilitate the replacement of the drying lamps 203.

[0043] Specifically, first slide rails 8 are fixed on both side plates 213 connecting the cover body 201 and the two ends of the cross bar 202. The first slide rails 8 are arranged along the length direction of the side plates 213. First sliders 9 slidably connected to the first slide rails 8 are fixed at both ends of the cross bar 202 to achieve sliding between the cross bar 202 and the cover body 201; one end of the cross bar 202 extends out of the cover body 201, and an external threaded portion is fixed to the end of the cross bar 202 extending out of the cover body 201, and a fastening member 10 is screwed on the external threaded portion. The fastening member 10 is selected as a bolt. By rotating the fastening member 10, one end of the fastening member 10 can be fastened to the outer side of the side plate 213 to achieve the fixation of the cross bar 202. A clearance hole 11 parallel to the first slide rail 8 is opened on the side plate 213 near the horizontal center line. The external thread portion passes through the clearance hole 11 and slides along the length direction of the clearance hole 11. The clearance hole 11 allows one end of the cross bar 202 to extend out of the cover body 201, which facilitates the position adjustment of the cross bar 202 and ensures the normal sliding of the cross bar 202.

[0044] Two parallel second slide rails 12 are fixed on the long sides of the top plate 214, and a gantry frame 13 is slidably connected to the second slide rails 12, with the opening of the gantry frame 13 facing downward and spanning the width direction of the cover body 201. Second sliders 14 are fixed at the two lower ends of the gantry frame 13, and the second sliders 14 are slidably connected to the second slide rails 12; a partition plate 15 is slidably connected in the opening of the gantry frame 13, and both ends of the partition plate 15 are slidably connected in the gantry frame 13 along the height direction, and the partition plate 15 is arranged along the width direction of the top plate 214, and the partition plate 15 is perpendicular to the top plate 214. A through hole 16 is opened on the top plate 214, and the through holes 16 are arranged at intervals along the direction of the parallel cross bar 202. When the partition plate 15 slides up and down, it enters or slides out of the cover body 201 along the through hole 16; the height of the partition plate 15 is similar to the height of the side plate 213. When the partition plate 15 moves downward to the lowest position, the lower end of the partition plate 15 is spaced from the supporting surface 4 to prevent the lower end of the partition plate 15 from contacting the carpet.

[0045] The number of through holes 16 is greater than the number of partitions 15, and the partitions 15 can be slid to a position opposite to the through holes 16 as needed for use. When the partitions 15 enter the cover 201, the cavity in the cover 201 can be divided to form cavities of different sizes, which can reduce the situation where heat is too dispersed inside the cover 201; and some drying lamps 203 far from the carpet can be turned off, so that the heat can be concentrated in the cavity opposite to the carpet, thereby improving the heating and drying efficiency and saving power.

[0046] Specifically, a screw rod 17 is vertically screwed near the middle of the upper end of the gantry frame 13, and the lower end of the screw rod 17 is rotatably connected to the upper end of the partition plate 15. The position between the screw rod 17 and the partition plate 15 is relatively static. When the screw rod 17 rotates, the partition plate 15 can be pulled up and down synchronously. At the same time, because the cover body 201 has a high strength, it can be operated by stepping on the top plate 214 and close to the screw rod 17, which is convenient and quick.

[0047] Reference Figure 1 and Figure 4 , since the glue has some odor when drying, it will affect the surrounding environment; therefore, an exhaust fan 18 is installed on the outside of the cover body 201, and the air inlet of the exhaust fan 18 is connected to the inside of the cover body 201, and the air outlet of the exhaust fan 18 is connected to the exhaust pipe 19, and a collecting pipe 20 is fixed at the end of the exhaust pipe 19 away from the exhaust fan 18, and one end of the collecting pipe 20 can be connected to the exhaust gas treatment equipment (not shown in the figure). Among them, the collecting pipe 20 is horizontally arranged at the upper position of the room along the sliding direction of the cover body 201, and a strip hole 21 is opened along the length direction of the horizontal side of the collecting pipe 20; a plurality of flexible curtain strips 22 covering the strip holes 21 are fixed at the upper end of the collecting pipe 20, and the flexible curtain strips 22 are selected as rubber sheets, which can play a certain role in sealing the strip holes 21 and reduce the odor in the collecting pipe 20. The end of the exhaust pipe 19 away from the exhaust fan 18 extends upward and passes through the strip hole 21 to enter the collecting pipe 20.

[0048] Since the cover body 201 needs to move a long distance and the exhaust pipe 19 moves synchronously with the cover body 201, when the cover body 201 slides, the flexible curtain strip 22 swings and bends, so that one end of the exhaust pipe 19 can slide along the strip hole 21. After the exhaust pipe 19 passes through the flexible curtain strip 22, the flexible curtain strip 22 returns to its initial position covering the strip hole 21.

[0049] The upper edge 23 and the lower edge 24 of the collecting pipe 20 located on both sides of the strip hole 21 are staggered on the vertical plane. The side of the collecting pipe 20 provided with the strip hole 21 and the side opposite to the strip hole 21 are vertical planes. The distance between the lower edge 24 and the side opposite to the strip hole 21 is smaller than the distance between the upper edge 23 and the side opposite to the strip hole 21, so as to form a staggered position. The upper end of the flexible curtain strip 22 is bonded and fixed to the inner side of the upper edge 23. The lower end of the flexible curtain strip 22 is located in the collecting pipe 20 and the outer side of the flexible curtain strip 22 abuts against the inner side of the lower edge 24. The lower edge 24 has a sufficient distance from the lowest position of the collecting pipe 20, so that the lower end of the flexible curtain strip 22 is not easy to run out of the strip hole 21 when swinging. At the same time, a counterweight block 25 is fixed at the lower end of the flexible curtain strip 22, so that the flexible curtain strip 22 can return to the position of covering the strip hole 21 more quickly after the exhaust pipe 19 passes.

[0050] The implementation principle of a drying device in the embodiment of the present application is as follows: lay the carpet on the support part 1 with the back side facing upward, and then apply glue; then drive the cover 201 to slide through the driving member 3, so that the driving member 3 slides to a position covering the carpet, and then turn on the drying lamp 203 to dry the carpet. After drying, the drying box 2 can be moved further to the top of the next carpet to be dried, and the dried carpet can be cooled at room temperature.

[0051] Moreover, the relative position of the carpet and the opening of the cover 201 is adjusted by sliding the position of the cross bar 202, so that the cross bar 202 is concentrated directly above the carpet, thereby improving the drying efficiency. At the same time, after the partition plate 15 is slid downward into the cover 201, the cavity in the cover 201 can be divided, the corresponding cavity directly above the carpet can be reduced, and the drying lamp 203 far outside the corresponding cavity can be turned off, so that the heat in the cavity is not easy to spread, and energy can be saved at the same time.

[0052] Finally, since there is no need to use a large conveyor belt, the existing ground is directly combined as the support part 1, which changes the traditional method of moving the carpet with a conveyor belt. The drying box 2 is directly set to be movable, eliminating the conveyor belt. Therefore, it is only necessary to slide a drying box 2 directly on the ground, which is convenient and quick, and achieves the effect of facilitating the production and assembly of the drying device, facilitating maintenance, and saving costs.

[0053] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
