In the deep processing of pearl cotton, one piece of pearl cotton is usually partially heated and melted by electric heating blowing or electric heating plate ironing, and then the two pieces of pearl cotton are bonded. Whether the above bonding method uses an automatic bonding machine or manual bonding, there are the following problems: of the two pieces of pearl cotton to be bonded, only one piece is in a heated and melted state, and the other piece is in a normal state without preheating. In this state, the heated pearl cotton needs to melt more materials to bond the two firmly, which not only increases the heating time, but also one piece of pearl cotton is burned more, which seriously affects the bonding quality and effect.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work belong to the protection scope of the utility model.

[0029] The following is combined with Figure 1 To Attachment Figure 6 And specific embodiments describe the present invention in detail.

[0030] like Figure 1-6 As shown, the utility model provides an automatic pearl cotton bonding machine, which is used for bonding two pieces of pearl cotton stacked up and down, comprising a frame 1, a material taking mechanism 2 arranged on the top of the frame 1, and a feeding mechanism 3 and a heating mechanism 4 movably arranged on both sides of the material taking mechanism 2, the feeding mechanism 3 and the heating mechanism 4 can move horizontally in the direction of the material taking mechanism 2, the feeding mechanism 3 is used to transport the two pieces of pearl cotton stacked together to the bottom of the material taking mechanism 2, the material taking mechanism 2 descends to take away one of the pearl cottons, the heating mechanism 4 heats one of the pearl cottons (the upper pearl cotton or the lower pearl cotton), and then the heated pearl cotton is bonded with the unheated pearl cotton; refer to Figure 1 and Figure 2 The present application does not limit the number of the material taking mechanism 2, the feeding mechanism 3 and the heating mechanism 4. When the bonding machine is a single-station device, there is one material taking mechanism 2, one feeding mechanism 3 and one heating mechanism 4 respectively; when the bonding machine is a double-station device, there are two material taking mechanisms 2 and two feeding mechanisms 3 respectively, and there is at least one heating mechanism 4; when the bonding machine is a three-station device, there are three material taking mechanisms 2 and three feeding mechanisms 3 respectively, and there is at least one heating mechanism 4; the bonding machine specifically designed with several stations can be designed by technicians in this field according to actual usage conditions, and the present application does not make specific limitations.

[0031] See, 3. Figure 4The feeding mechanism 3 of the present application includes a horizontally movable base 31 and a discharge plate 32. The discharge plate 32 is liftably arranged on the horizontally movable base 31 through a lifting component 33. The horizontally movable base 31 can only move horizontally, and the vertical distance between it and the heating mechanism 4 is fixed, while the discharge plate 32 is liftably arranged on the horizontally movable base 31, and the vertical distance between it and the heating mechanism 4 is adjustable. The present application cleverly arranges the discharge plate 32 into a liftable structure, and preheats the other piece of pearl cotton while the heating mechanism 4 heats one piece of pearl cotton. Compared with the scheme of heating only one piece of pearl cotton in the prior art, the present application preheats the unscalded piece of pearl cotton before the two pieces of pearl cotton are bonded. After preheating, the heating time of the pearl cotton to be heated can be appropriately shortened to reduce the melting depth of the heated pearl cotton and improve the bonding quality of the pearl cotton.

[0032] In one embodiment, the upper piece of pearl cotton is heated and the lower piece of pearl cotton is preheated. The specific process is: two pieces of pearl cotton are stacked on the discharge plate 32 and moved to the bottom of the feeding mechanism 2. When the feeding mechanism 2 takes away the upper piece of pearl cotton on the discharge plate 32, the heating mechanism 4 moves to the top of the feeding mechanism 3. The feeding mechanism 2 descends and places the upper piece of pearl cotton on the heating mechanism for heating and partial melting. At the same time, the discharge plate 32 moves upward to a preset position. At this time, while the heating mechanism 4 heats the upper piece of pearl cotton, the lower piece of pearl cotton is preheated. After preheating, the heating time of the upper piece of pearl cotton can be appropriately shortened to reduce the melting depth of the upper piece of pearl cotton and improve the bonding quality of the pearl cotton.

[0033] In another embodiment, the lower piece of pearl cotton is heated and the upper piece of pearl cotton is preheated. The specific process is: two pieces of pearl cotton are stacked on the discharge plate 32 and moved to the bottom of the material taking mechanism 2. When the material taking mechanism 2 takes away the upper piece of pearl cotton on the discharge plate 32, the material taking mechanism and the heating mechanism are kept at a preset vertical distance. After that, the heating mechanism 4 moves to the top of the feeding mechanism 3, and the discharge plate 32 rises through the lifting component 33 to contact the heating mechanism 4 to heat the lower piece of pearl cotton. It can be understood that the heating mechanism of the present application can heat the lower piece of pearl cotton or the upper piece of pearl cotton. The specific selection can be based on the material to be heated and is not specifically limited.

[0034] In the embodiment of the present application, the heating mechanism 4 is used as an example to heat and melt the upper piece of pearl cotton.

[0035] For details, see Figure 3 and Figure 4The lifting assembly 33 of the embodiment of the present application includes a nut seat 331 rotatably arranged on the horizontal movable base 31, a screw rod 332 matched with the nut seat 331, and a first driving assembly 34 driving the nut seat 331 to rotate; the lower end of the screw rod 332 penetrates the horizontal movable base 31 and extends downward, the upper end of the screw rod 332 is connected to the discharge plate 32, the first driving assembly 34 drives the nut seat 331 to rotate, and the rotation of the nut seat 331 drives the screw rod 332 to move vertically up and down, thereby realizing the vertical up and down movement of the discharge plate 32. In this embodiment, the lifting and lowering of the discharge plate is realized by the cooperation of the nut seat and the screw rod, which has the advantages of high precision and high efficiency. It can be understood that all lifting assemblies that can realize the lifting function of the discharge plate 32 in this application belong to the protection scope of the present utility model, and the lifting assembly 33 shown in the figure is only one of the embodiments, but it is not limited to this.

[0036] Specifically, there are multiple nut seats 331 in the embodiment of the present application, and they are circumferentially arranged on the horizontal movable base 31. A synchronous wheel 333 is fixedly sleeved on the upper end of each nut seat 331, and a synchronous belt 334 is sleeved on multiple synchronous wheels 333. When the first driving component 34 drives one of the nut seats 331 to rotate, it will drive the synchronous wheel 334 on it to rotate, and the synchronous wheel 334 drives other nut seats 331 to rotate through the synchronous belt 334, thereby realizing the synchronous lifting of multiple screw rods 332. For example, the horizontal movable base 31 and the discharge plate 32 are both square plates, and the nut seats 331 are arranged at the four corners of the square plate to achieve uniform support for the discharge plate 32.

[0037] Specifically, a plurality of guide cylinders 335 are fixed to the upper surface of the horizontal movable base 31 of the embodiment of the present application, and a guide column 336 is arranged in each guide cylinder 335. The lower end of the guide column 336 extends downward after penetrating the horizontal movable base 31, and the upper end of the guide column 336 is fixedly connected to the discharge plate 32. Preferably, a guide cylinder 335 is fixed next to each nut seat 331, and the guide cylinder 335 and the guide column 336 guide the lifting and lowering of the discharge plate 32, so as to prevent the nut seat 331 from being deflected by force during the rotation process, resulting in the deflection of the discharge plate 32, which ultimately affects the horizontality of the upper end surface of the discharge plate 32, and indirectly affects the bonding quality.

[0038] Specifically, the first drive assembly 34 in the embodiment of the present application includes a first motor 341, a driving wheel 342 fixedly mounted on the motor shaft of the first motor 341, a driven wheel 343 fixedly mounted on the lower end of one of the nut seats 331, and a transmission belt 344 mounted on the driving wheel 342 and the driven wheel 343. The first motor 341 drives the driving wheel 342 to rotate, and the driving wheel 342 drives the driven wheel 343 to rotate through the transmission belt 344. The rotation of the driven wheel 343 drives one of the nut seats 331 to rotate, and the synchronous wheel 333 at the upper end of the nut seat 331 drives the other nut seats 331 to rotate through the synchronous belt 334, thereby driving all the screw rods 332 and the guide column 336 to move up and down. It can be understood that the function of the first drive assembly 34 is to drive one of the nut seats 331 to rotate. Therefore, the structure of the first drive assembly 34 is not specifically limited. The above is only one embodiment, but other first drive mechanisms 34 that can realize the rotation of the nut seat 331 also belong to the protection scope of the present use novel.

[0039] In a preferred embodiment, at least one tensioning wheel 337 is also provided on the outer side of the synchronous belt 334. The tensioning wheel 337 is rotatably provided on the fixed shaft. A movable groove corresponding to the tensioning wheel 337 is provided on the horizontal movable base 31. The lower end of the fixed shaft is movably provided in the movable groove. The movable groove is a strip groove. The lower end of the fixed shaft is slidably provided in the strip groove and is detachably fixed in the strip groove by a fixing member. The tensioning force of the synchronous belt 334 will decrease during long-term use, causing the synchronous belt 334 to become loose. The present application provides a movable tensioning wheel 337, which can be adjusted at any time according to the use of the synchronous belt 334, to ensure the synchronous rotation of all nut seats 331, so that the upper surface of the discharge plate 32 always remains in a horizontal state.

[0040] For details, see Figure 4 , the horizontal movable base 31 of the embodiment of the present application is moved on the frame 1 through the second driving assembly 35. The present application does not limit the specific structure of the second driving assembly 35, and those skilled in the art can design it according to actual conditions; in an optional embodiment, the second driving assembly 35 includes a second motor 351, a reduction device 352 connected to the second motor 351, and a driving shaft 353 extending from the reduction device 352 to both sides, and a gear 354 is fixed at both ends of the driving shaft 353, and a rack 11 corresponding to the gear 354 is fixed on the frame 1; the two ends of the driving shaft 353 are fixedly connected to the horizontal movable base 31 through a bearing seat 355. It should be noted that the reduction device 352 is a dual-output structure, which can reduce the speed of the second motor 351 and then output it, and through the gears 354 at both ends of the driving shaft 353, the horizontal movable base 31 can reciprocate horizontally along the extension direction of the rack 11.

[0041] Specifically, a slider 356 is fixed to the lower surface of the horizontal movable base 31 of the embodiment of the present application, a linear guide rail 12 is provided on the frame 1, and the slider 356 is slidably connected to the linear guide rail 12. The setting of the slider 356 and the linear guide rail 12 provides guidance for the movement of the horizontal movable base 31 and enables it to perform reciprocating horizontal movement more stably.

[0042] For details, see Figure 5 The heating mechanism 4 of the embodiment of the present application includes a heating plate 41, and the two ends of the heating plate 41 are moved by belt transmission mechanisms 42 respectively. The belt transmission mechanisms 42 at both ends include a first transmission wheel 421, a second transmission wheel 422 arranged along the interval, and a conveyor belt 423 sleeved on the first transmission wheel 421 and the second transmission wheel 422, and both ends of the heating plate 41 are fixedly connected to the conveyor belt 423; the belt transmission mechanism 42 is driven and transmitted by a third driving component, and the third driving component includes a third motor 424, and a synchronous shaft 425 that is transmission-connected to the output shaft of the third motor 424 through a reducer, and the two ends of the synchronous shaft 425 are respectively inserted into the first transmission wheels 421 of the two belt transmission mechanisms 42.

[0043] In an optional embodiment, a sliding component is provided at the lower end of the heating plate 41, which is slidably set on the frame 1 through the sliding component. The sliding component can be a slider and a linear slide rail, or other guide members. The sliding component provides guidance for the movement of the heating plate 41 and enables it to perform reciprocating horizontal movement more stably.

[0044] Specifically, a processing station is provided on the frame 1 of the embodiment of the present application, and the feeding mechanism 3 and the heating mechanism 4 can be moved to the processing station; the material taking mechanism 2 includes a material taking plate 21, which is located directly above the processing station and can be vertically moved to the material discharge plate 32 of the feeding mechanism 3 and the heating plate 41 of the heating mechanism 4, and material taking needles are arranged at intervals on the bottom surface of the material taking plate 21. The present application does not elaborate on the lifting part of the material taking mechanism 2, and those skilled in the art can refer to the existing technology for design.

[0045] Specifically, a finished product output mechanism 5 is provided below each material taking mechanism, and the finished product output mechanism 5 is used to transport the bonded pearl cotton out.

[0046] like Figure 1As shown, in an optional embodiment, the bonding machine is a single-station bonding machine, and there is one material taking mechanism 2, one feeding mechanism 3 and one heating mechanism 4 respectively, and the feeding mechanism 3 and the heating mechanism 4 are respectively arranged on the opposite sides of the material taking mechanism 2, that is, the moving directions of the feeding mechanism 3 and the heating mechanism 4 are consistent, and the feeding mechanism 3 and the heating mechanism 4 are respectively moved to the bottom of the material taking mechanism 2 to complete the bonding of the two pieces of pearl cotton. It can be understood that in other embodiments, the feeding mechanism 3 and the heating mechanism 4 can be respectively arranged on the adjacent two sides of the material taking mechanism, that is, the moving directions of the feeding mechanism 3 and the heating mechanism 4 are different, as long as it can be moved to the bottom of the material taking mechanism 2, it falls into the protection scope of the present utility model.

[0047] like Figure 2 As shown, in another optional embodiment, the bonding machine is a double-station bonding machine, and there are two material picking mechanisms 2 and two feeding mechanisms 3, while only one heating mechanism 4 is provided. The feeding mechanism 3 and the heating mechanism 4 are respectively provided on the adjacent two sides of the material picking mechanism 2, that is, the moving directions of the feeding mechanism 3 and the heating mechanism 4 are different, and the heating mechanism 4 is provided between the two material picking mechanisms 2, and reciprocates under the two material picking mechanisms 2. In this embodiment, the heating mechanism 4 is provided as one, which not only reduces the volume of the equipment, but also saves the equipment cost, and is more conducive to the promotion of the equipment. It can be understood that in other embodiments, the heating mechanism 4 can also be designed as two, and can also be provided on the opposite sides of the material picking mechanism 2. As long as the two heating mechanisms 4 can be moved to the bottom of the two material picking mechanisms 2 respectively, it falls within the protection scope of the present utility model.

[0048] The working principle of the automatic bonding machine of the present application is as follows: in the initial state, the heating mechanism 4 moves horizontally away from the processing station, and the feeding mechanism 3 moves horizontally to the processing station. The operator stacks the upper piece of pearl cotton and the lower piece of pearl cotton on the discharge plate 32, and starts the second motor 351 to move the horizontally movable base 31 to the bottom of the feeding plate 21. The feeding plate 21 moves downward and takes away the upper piece of pearl cotton through the feeding needle, and moves vertically upward. After that, the heating mechanism 4 moves horizontally to the processing station, and the feeding plate 21 moves downward and takes away the upper piece of pearl cotton. The cotton is placed on the heating plate 41. At the same time, the first motor 341 is started to move the discharge plate 32 upward to the preset position. When the heating plate 41 heats the upper piece of pearl cotton, the lower piece of pearl cotton is preheated at the same time. After heating for a certain period of time, the bottom surface of the upper piece of pearl cotton melts and softens, and the upper surface of the lower piece of pearl cotton softens. Then, the material taking plate 21 descends to take away the heated upper piece of pearl cotton. After the heating mechanism 4 moves horizontally away from the processing station, the material taking plate 21 descends to press the upper piece of pearl cotton onto the lower piece of pearl cotton to complete the bonding of the two pieces of pearl cotton.

[0049] It should be noted that the present application does not specifically limit the timing of lifting and lowering the discharge plate 32 on the feeding mechanism 3. The above embodiment is described by taking the discharge plate 32 as an example after it moves to the processing station, but it is not limited to this. The discharge plate 32 can also be lifted and lowered at any position during the movement to the processing station, as long as it can rise to the preset position at the processing station and shorten the distance between it and the heating plate 41 to achieve the purpose of preheating the lower piece of pearl cotton. Similarly, the rising distance of the discharge plate 32 of the present application can be set according to the thickness of the pearl cotton to be processed.

[0050] The utility model is further described above with the help of specific embodiments, but it should be understood that the specific description here should not be construed as limiting the essence and scope of the utility model. Various modifications made to the above embodiments by ordinary technicians in this field after reading this specification are all within the scope of protection of the utility model.
