Description

Technical Field

[0001] The present invention relates to the technical field of non-woven fabric sizing machinery, and particularly relates to a non-woven fabric sizing device. Background Art

[0002] Artificial turf is a simulated turf made of non-living plastic chemical fiber products by artificial methods. It does not require the consumption of resources such as fertilizers and water necessary for the growth of natural turf, can meet the high-intensity sports needs for 24 hours a day, and has the advantages of simple maintenance, rapid drainage, and low maintenance costs. Therefore, artificial turf is widely used in the special competition venues for hockey, baseball, and rugby, the public practice fields for sports such as football, tennis, and golf, or as floor paving to beautify the indoor environment.

[0003] The laying of artificial turf usually involves bonding the connecting belt and the bottom surface of the artificial turf on the construction site. The connecting belt is generally made of non-woven fabric, and the adhesive is glue. The glue is respectively applied to the bottom of the joint of the artificial turf and the non-woven fabric, and then bonded. Finally, it is knocked with a rubber hammer or mechanically compacted.

[0004] At present, non-woven fabric sizing is carried out by pouring glue on the non-woven fabric and then using a push plate to push the glue evenly and then covering the artificial turf for bonding. However, this sizing method has low automation and low sizing efficiency.

[0005] Therefore, the present invention proposes a non-woven fabric sizing device. Summary of the Invention

Detailed implementation manners

[0030] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby declared that the orientation terms such as up, down, left, right, front, back, inside, and outside that appear or will appear in the present invention are only based on the accompanying drawings of the present invention, and they do not specifically limit the present invention.

[0031] Refer to the attached Figure 1-3A non-woven fabric glue application device includes a cart 1 consisting of a glue storage chamber and a glue outlet chamber, the glue storage chamber is used to store glue, and the glue outlet chamber is used to discharge glue. A guide pipe 111 for glue to flow out is provided between the glue storage chamber and the glue outlet chamber of the cart 1, and the guide pipe 111 connects the glue storage chamber and the glue outlet chamber of the cart 1. A glue outlet 11 is provided on the glue outlet chamber of the cart 1, and the glue outlet 11 is fixedly connected to the bottom of the rear end of the cart 1. One end of the guide pipe 111 is connected to the glue storage chamber, and the other end is connected to the glue outlet 11. A first rotating shaft 103 is provided in the cart 1, and a reciprocating screw rod 106 is provided in the cart 1. The first Rollers are installed at both ends of the rotating shaft 103 and the reciprocating screw rod 106, and the rollers facilitate the movement of the cart 1. A synchronous belt 104 is provided between the first rotating shaft 103 and the reciprocating screw rod 106, and the synchronous belt 104 makes the first rotating shaft 103 and the reciprocating screw rod 106 rotate synchronously. A double-axis motor 13 is fixedly connected to the first rotating shaft 103, and the double-axis motor 13 is used to drive the first rotating shaft 103 to rotate. A first bevel gear 14 is also fixedly connected to the first rotating shaft 103. A second rotating shaft 16 is also rotatably connected in the cart 1, and a glue pushing component is provided on the second rotating shaft 16, which automatically pushes out the glue as the cart 1 moves.

[0032] Specific reference Figure 3 The glue pushing assembly is arranged on the second rotating shaft 16, and the glue pushing assembly includes a second bevel gear 15, and the second bevel gear 15 is fixedly connected to the second rotating shaft 16, and the second bevel gear 15 is meshed with the first bevel gear 14. A screw 19 is also rotatably connected in the glue holding chamber of the cart 1, and a belt 17 is provided between the ends of the screw 19 and the second rotating shaft 16 that are close to each other. A glue pushing plate 18 is threadedly connected to the screw 19, and the glue pushing plate 18 is built in the glue holding chamber of the cart 1, and the edge of the glue pushing plate 18 is in contact with the inner wall of the glue holding chamber. The screw 19 is used to drive the glue pushing plate 18 to move, and the pushing member 18 is used to push the glue toward the direction of the guide tube 111.

[0033] Before using this device, it is necessary to first fill the glue chamber with glue. A sealing member 101 for adding glue is threadedly connected to the top of the trolley 1. By opening the sealing member 101, glue can be poured into the glue chamber. When the glue is injected into the glue chamber, it will flow into the diversion tube 111 and be discharged from the glue outlet 11. Therefore, this device controls the discharge of glue by setting an adjustment component on the glue outlet 11. The adjustment component is arranged on the glue outlet 11. The adjustment component includes a rotating member 2. The rotating member 2 is connected to the glue outlet 11 through symmetrically distributed connecting blocks. A baffle 21 is rotatably connected to the rotating member 2. The baffle 21 fits against the bottom of the glue outlet 11. The baffle 21 is used to adjust the outflow of glue. A torsion spring 22 is provided between the baffle 21 and the symmetrically distributed connecting blocks. The torsion springs 22 are wound around the adjacent rotating members 2 respectively. The torsional force generated by the torsion springs 22 is used to drive the baffle 21 to fit against the bottom of the glue outlet 11.

[0034] When the glue is poured into the glue chamber, the baffle 21 is tightly pressed against the glue outlet 11 under the elastic force of the torsion spring 22, playing a role in sealing the glue and avoiding waste of glue during the glue filling process.

[0035] To facilitate judging whether the glue chamber is full of glue, this device is realized by setting a ventilation pipe 102 on the trolley 1. The specific judgment criteria are as follows. The ventilation pipe 102 is provided on the trolley 1. The ventilation pipe 102 is built into the trolley 1 and extends into the glue chamber. When injecting glue, both the sealing member 101 and the ventilation pipe 102 are opened simultaneously. Glue is poured into the glue chamber through the sealing member 101. As the glue filling operation continues, the gas originally retained in the glue chamber will gradually escape from the ventilation pipe 102. The baffle 21 in the glue outlet chamber plays a blocking role for the glue. When the glue overflows from the ventilation pipe 102, it means that the glue chamber is full of glue, and at this time, the glue filling is stopped.

[0036] Subsequently, the sealing member 101 and the ventilation pipe 102 are closed, and the double-axis motor 13 is started to drive the first rotating shaft 103 to rotate. Through the conduction of the synchronous belt 104, the reciprocating lead screw 106 is driven to rotate, and then the rollers on the first rotating shaft 103 and the reciprocating lead screw 106 rotate synchronously, and the rotation of the rollers makes the trolley 1 move.

[0037] Meanwhile, the rotation of the first rotating shaft 103 drives the first bevel gear 14 to rotate and mesh with the second bevel gear 15, thereby driving the second rotating shaft 16 to rotate. The rotation of the second rotating shaft 16 drives the screw 19 to rotate through the conduction of the belt 17, thereby driving the glue pushing plate 18 to move in the direction of the diversion pipe 111. At this time, the glue is pushed to the baffle 21 at the glue outlet 11. Under the action of the continuous glue pushing action of the glue pushing plate 18, the baffle 21 will flip, the torsion spring 22 will deform, and the glue will flow out smoothly from the glue outlet 11. This step only requires the start of the dual-axis motor 13 to achieve two effects. One is that through the transmission of the synchronous belt 104, the roller is driven to rotate, so that the trolley 1 moves. The other is that during the movement of the trolley 1, through the meshing of the first bevel gear 14 and the second bevel gear 15 and the transmission of the belt 17, the pushing member 18 moves on the screw 19, realizing the movement action of the trolley 1. The glue pushing action of the pushing member 18 and the glue discharging action at the glue outlet 11 are carried out synchronously, so as to improve the glue application efficiency and reduce the labor cost.

[0038] In order to make the trolley 1 move directionally along the laying direction of the non-woven fabric, the present invention realizes this effect by arranging a pusher frame 105 on the trolley 1. The pusher frame 105 is fixedly connected to the trolley 1, and the pusher frame 105 facilitates the relevant staff to control the moving direction of the trolley 1.

[0039] During the operation of the device, when the glue flows from the glue outlet 11 to the non-woven fabric, it is necessary to push the glue evenly to facilitate the bonding of the artificial turf. At the same time, to increase the bonding degree between the artificial turf and the non-woven fabric, the inventor of the present invention realizes this by arranging a glue scraping plate 12 on the outer wall of the glue outlet 11.

[0040] The outer wall of the glue outlet 11 is fixedly connected with a glue scraping plate 12 for pushing the glue evenly. The glue scraping plate 12 is provided with evenly distributed soft teeth, and the soft teeth are used to push the glue evenly and form certain patterns.

[0041] According to the foregoing description, after the glue flows out from the glue outlet 11, with the movement of the trolley 1 driving the glue scraping plate 12 to move, the glue scraping plate 12 pushes the glue evenly and forms certain patterns. These patterns can increase the contact area between the glue and the non-woven fabric, thereby improving the bonding force and making the bonding between the non-woven fabric and the artificial turf closer. In addition, the evenly distributed soft teeth on the glue scraping plate 12 have a certain flexibility, and the purpose is to reduce the wear of the non-woven fabric caused by the soft teeth.

[0042] Usually, before using this device, the non-woven fabric needs to be laid on the construction site in advance. During the laying process, there will be dust, paper scraps and other sundries left on the non-woven fabric. After the sundries are mixed with the glue, the bonding force is reduced, thus affecting the glue application effect. Therefore, the present invention realizes the effect of cleaning the sundries on the non-woven fabric by arranging a cleaning component on the reciprocating screw rod 16.

[0043] Reference Figure 6-7, the cleaning component is arranged on the reciprocating screw rod 16. The cleaning component includes a moving part 3, which is threadedly connected to the reciprocating screw rod 16. The moving part 3 can move left and right on the reciprocating screw rod 16. Rack bars 31 are fixedly connected to both ends of the moving part 3. A blocking block 32 is also fixedly connected to the moving part 3. Symmetrically distributed fixing parts 33 are fixedly connected to the rear outer wall of the cart 1. Third rotating shafts 34 are fixedly connected to the fixing parts 33. Wedge-shaped parts 36 are slidably connected to the third rotating shafts 34. The wedge-shaped parts 36 can be in extrusion fit with the blocking block 32. A positioning rod 301 is arranged between the wedge-shaped part 36 and the adjacent fixing part 33. The positioning rod 301 is used to guide the movement of the wedge-shaped part 36. Energy storage springs 302 are wound around the positioning rods 301. The energy storage springs 302 are used to drive the wedge-shaped parts 36 to reset. Cleaning parts 35 are slidably connected to the third rotating shafts 34. The cleaning parts 35 are used to sweep the sundries on the non-woven fabric. Grooves are arranged on the sides of the cleaning parts 35 close to each other. The wedge-shaped parts 36 are slidably connected to the third rotating shafts 34 in the grooves of the adjacent cleaning parts 35. The purpose of arranging the grooves on the cleaning parts 35 is that the rotation action of the cleaning parts 35 does not affect the wedge-shaped parts 36. Rotating gears 37 are fixedly connected to the bottoms of the cleaning parts 35. The rotating gears 37 are meshed with the adjacent rack bars 31.

[0044] By starting the double-shaft motor 13, the movement of the cart 1 and the glue-pushing action of the glue-pushing plate 18 are synchronized. The reciprocating screw rod 16 rotates, driving the moving part 3 thereon. The rack bars 31 and the blocking block 32 both move left and right. The following effects will occur during this linkage process. First, the moving part 3 is linked to move left and right, aiming to push the sundries on the non-woven fabric to the two side edges of the non-woven fabric. Second, the left and right movement of the moving part 3 links the left and right movement of the adjacent rack bars 31 and meshes with the adjacent rotating gears 37, driving the adjacent rotating gears 37 to rotate, and then driving the adjacent cleaning parts 35 to rotate. Third, during the left and right movement of the moving part 3, the sundries on the non-woven fabric will continue to be pushed to both sides. The moving part 3 drives the blocking block 32 to move left and right and is in extrusion fit with the inclined surface of the adjacent wedge-shaped part 36. Under the restriction of the positioning rod 301, the adjacent wedge-shaped part 36 moves upward along the third rotating shaft 34. At this time, the energy storage spring 302 deforms. Since the wedge-shaped part 36 is slidably connected to the third rotating shaft 34 in the groove of the adjacent cleaning part 35, therefore, the wedge-shaped part 36 and the cleaning part 35 move upward synchronously, aiming not to affect the moving part 3 to push the sundries to the edge of the non-woven fabric.

[0045] After the blocking block 32 is disengaged from the wedge 36, under the action of the energy storage spring 302, the wedge 36 moves downward to reset, thereby driving the cleaning member 35 to move downward. The wedge 36 and the cleaning member 35 move downward and reset synchronously. During this process, the moving member 3 still maintains the state of moving left and right, and the rack 31 thereon will mesh with the adjacent rotating gear 37 again, and the cleaning member 35 rotates again. To sum up, by the reciprocating left and right movement of the moving member 3, the sundries are first pushed to both side edges, and then through the reciprocating up and down movement and rotation of the cleaning member 35, the sundries at both side edges of the non-woven fabric are swept away.

[0046] To improve the viscosity between the non-woven fabric and the artificial turf, it is necessary to ensure that the glue falls onto the cleaned non-woven fabric. However, when the device is initially used, relevant personnel need to clean the non-woven fabric in advance so that the non-woven fabric at the position where the cart 1 is located is in a cleaned state. Subsequently, the dual-axis motor 13 is started, the cart 1 moves, and the glue pushing plate 18 pushes the glue into the diversion pipe 111 and then discharges it from the glue outlet 11. The cleaning action of the cleaning member 35 and the glue discharging action of the glue outlet 11 are carried out synchronously, so as to realize that the glue always falls on the cleaned non-woven fabric.

[0047] In addition, the inventor of the present invention further improves the cleaning effect of the non-woven fabric and increases the viscosity of the glue. Brushes are provided at the bottoms of both the moving member 3 and the cleaning member 35, and the brushes are made of flexible materials. This material will not wear the non-woven fabric, and at the same time, the movement of the brushes will not drive the non-woven fabric to move. In addition, the contact area between the moving member 3, the cleaning member 35 and the non-woven fabric is increased to further improve the cleaning effect.

[0048] However, when the non-woven fabric is laid, it is inevitable that the non-woven fabric bulges locally, resulting in unevenness, which causes uneven distribution of the glue and thus affects the viscosity between the non-woven fabric and the artificial turf. Therefore, in this embodiment, a flattening assembly is provided on the cart 1 to flatten the non-woven fabric in advance before the glue is discharged from the cart 1, so as to improve the effect of subsequent glue application work.

[0049] For specific reference Figure 8 , symmetrically distributed connecting columns 4 are fixedly connected to the bottom of the cart 1, a fixing plate is fixedly connected between the upper ends of the connecting columns 4, a flattening member 41 is slidably connected between the lower ends of the connecting columns 4, the flattening member 41 can slide on the connecting columns 4, the flattening member 41 can flatten the non-woven fabric, compression springs 42 are provided between the flattening member 41 and the fixing plate on the connecting columns 4, the compression springs 42 are wound around the adjacent connecting columns 4, and the compression springs 42 are used to drive the flattening member 41 to reset.

[0050] When using this device and placing the trolley 1 on the non-woven fabric, first lift the flattening member 41 upward. During this process, the flattening member 41 moves upward a certain distance on the connecting column 4, deforming the compression spring 42. Subsequently, under the action of the compression spring 42, the flattening member 41 moves downward and resets on the connecting column 4, thereby achieving the effect of flattening the non-woven fabric.

[0051] After the glue application work is completed and all the glue in the glue storage cavity of this device has been pushed out, there will still be residual glue in the air vent pipe 102 and the diversion pipe 111 that cannot be discharged. The glue will solidify over time and cause blockage of the air vent pipe 102 and the diversion pipe 111. Therefore, the present invention utilizes air pressure changes and a one-way valve 110 provided on the diversion pipe 111 to discharge the residual glue in the air vent pipe 102 and the diversion pipe 111.

[0052] Specific reference Figure 3 , a one-way valve 110 is provided on the diversion pipe 111. The one-way valve 110 is connected to the glue storage cavity in a through manner. The one-way valve 110 mainly consists of a valve seat, a valve plate, a spring, and a lift limiter. Under the action of the one-way valve 110, it is ensured that the glue only flows out from the diversion pipe 111 of the glue outlet cavity and does not flow back. This is the prior art and will not be elaborated here too much.

[0053] As described above, when this device is operating, the closing member 101 and the air vent pipe 102 are both in a closed state, and the glue storage cavity is in a sealed state. When all the glue in the glue storage cavity has been pushed out, at this time, the air vent pipe 102 is opened, so that external air only enters the glue storage cavity through the air vent pipe 102. Subsequently, the trolley 1 is retracted a certain distance, and the glue pushing plate 18 is driven to retract a certain distance. During the retraction process, the glue storage cavity is in a negative pressure state. The existence of the negative pressure accelerates the entry of external air from the air vent pipe 102 into the glue storage cavity, and at the same time presses the glue in the air vent pipe 102 back into the glue storage cavity. The residual glue in the diversion pipe 111 will not flow back into the glue storage cavity under the action of the one-way valve 110. Subsequently, the air vent pipe 102 is closed to make the glue storage cavity return to a sealed state. At this time, there is a certain amount of air and glue in the glue storage cavity. Then, the trolley 1 is pushed forward a certain distance, driving the glue pushing plate 18 to move towards the glue outlet 11. The air and glue in the glue storage cavity are squeezed into the diversion pipe 111 together. Under the action of air pressure and the glue pushing action of the glue pushing plate 18, the residual glue in the diversion pipe 111 is discharged from the glue outlet 11, achieving the effect of discharging the residual glue in the air vent pipe 102 and the diversion pipe 111.

[0054] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
