Detailed Description

The following description of the embodiments of the present invention will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

The arrow in fig. 5 indicates the moving direction of the complex mechanism.

As shown in fig. 1 to 5, a sponge processing apparatus includes a placement stage 2, a moving frame 3 movable in a first direction A1, a compounding mechanism 4, and an auxiliary mechanism 5, the placement stage 2 being for placing at least two layers of a composite material; the composite mechanism 4 is disposed on the movable frame 3 and is movable in the second direction A2, the composite mechanism 4 includes a hot-melt knife 41, the hot-melt knife 41 has a plate shape, the hot-melt knife 41 has a first heating surface 411 and a second heating surface 412 opposite to the first heating surface 411, the first heating surface 411 and the second heating surface 412 are capable of heating with the contact surfaces of the two layers of sponge 100, respectively, and one ends of the first heating surface 411 and the second heating surface 412 are gradually brought close to and connected; the auxiliary mechanism 5 is used for extruding two sponges 100 to be adhered to the first heating surface 411 and the second heating surface 412 for hot melting, and extruding the sponges 100 after the hot melting to be adhered and fixed; wherein the first direction A1 and the second direction A2 are perpendicular.

In this application, it relates to an apparatus capable of hot melt compounding a multi-layered sponge 100 or a single layer of sponge 100 with other materials.

The equipment adopts a hot melting technology, and materials to be compounded are compounded in a mode of heating and pressurizing, so that firm adhesion among different materials is realized. Compared with the traditional gluing mode, the compound mode is more environment-friendly and efficient, and can effectively reduce the cost and pollution caused by using glue.

The sponge 100 to be compounded is first placed on the placement table 2, and then the sponge 100 is moved to a preset position. Next, the compounding mechanism 4 is moved between the two layers of sponge 100 with the hot-melt knife 41 aligned between the two layers of sponge 100, the compounding mechanism 4 is activated, and the hot-melt knife 41 is heated. The position of the moving frame 3 is adjusted, the hot-melt knife 41 is driven to move between the sponges 100, the contact surfaces of the two sponges 100 are respectively contacted with the first heating surface 411 and the second heating surface 412 of the hot-melt knife 41, and the speed of the moving frame 3 is controlled to enable the surfaces of the sponges 100 to be melted. After the hot melt knife 41 is removed, the melted portions of the sponge 100 fit together and adhere firmly together after cooling. The compounding mode can effectively avoid the problem of using a large amount of glue and gluing equipment, and meanwhile, the compounding efficiency and quality are improved.

In the process of hot melting, in order to ensure that the sponge 100 is sufficiently contacted and melted by the hot-melt knife 41, an auxiliary mechanism 5 is added to the complex mechanism 4. The auxiliary mechanism 5 may employ a pressure roller or other suitable auxiliary device for applying a suitable pressure to closely adhere the two layers of sponge 100 to the hot melt knife 41 to ensure that the faces of the two layers of sponge 100 melt uniformly and adhere firmly after cooling.

The first heating surface 411 and the second heating surface 412 can be respectively heated with the contact surface of the two layers of sponge 100, that is, the surface where the sponge 100 melts later. The first heating surface 411 and the second heating surface 412 are at least partially parallel, and one end gradually approaches and connects and forms a tapered portion.

Specifically, the compound mechanism 4 further comprises a cross rod 42 and first screw rod devices 43 arranged at two ends of the cross rod 42, wherein the first screw rod devices 43 are arranged on the movable frame 3 and are in transmission connection with the cross rod 42, and are used for driving the cross rod 42 to lift; the mounting groove 421 is formed in the length direction of the cross rod 42, the hot-melt knife 41 is mounted in the mounting groove 421, at least part of the hot-melt knife 41 is exposed out of the mounting groove 421, a cooling channel 44 is formed between the hot-melt knife 41 and the inner wall of the mounting groove 421, the cooling channel 44 surrounds the hot-melt knife 41, a guide part 422 is arranged at one end, far away from the hot-melt knife 41, of the cross rod 42, and the guide part 422 is gradually narrowed from one end, close to the hot-melt knife 41, towards one end, far away from the hot-melt knife 41.

In the present application, the first screw means 43 is capable of driving the cross bar 42 to move in the second direction A2, i.e. in the height direction. In addition, in order to strengthen the hot-melt knife 41 and to avoid sagging of the middle of the hot-melt knife 41, the hot-melt knife 41 is mounted on the cross bar 42. This design can effectively maintain the stability of the hot melt knife 41, ensuring high quality and accuracy in the compounding process.

After the hot-melt knife 41 is installed, the heat generated by the hot-melt knife 41 is wrapped by the sponge 100 at both sides, resulting in a higher temperature in the middle position than at both sides and uneven heat distribution. To solve this problem, a cooling channel 44 is designed to cool the internal temperature, thereby ensuring uniform temperature distribution during the compounding process of the sponge 100. Thus, the condition that the sponge 100 is unevenly melted or is not melted locally in the compounding process can be effectively reduced, and the compounding quality and efficiency are improved, for example, the condition that the middle position is melted to the two end positions which are not melted, or the condition that the two end positions are melted and the middle position is excessively melted.

The characteristics of the sponge 100 are considered in the design of the device, when the composite mechanism 4 moves, the cross rod 42 is firstly contacted with the sponge 100, then the sponge 100 can be attached to the hot-melt knife 41, and the hot-melt knife 41 is in a dragged state relative to the sponge 100, so that the adhesion of melting substances of the sponge 100 can be reduced. The hot-melt knife 41 is contacted with the sponge 100, and the hot-melt surfaces of the sponges 100 on two sides are directly attached together under the heating action of the hot-melt knife 41, so that the compounding is completed.

The guide 422 in this arrangement tapers at the end closer to the hot melt knife 41 to the end farther from the hot melt knife 41, which allows the cross bar 42 to be more easily inserted between two layers of sponge 100 while reducing the likelihood that the cross bar 42 will push the sponge 100 into motion. The design of such guides 422 helps to improve the accuracy and stability of the compounding process.

Specifically, an air blowing device is connected to the cooling channel 44, and is used for blowing air into the cooling channel 44.

In the present apparatus, the temperature deviation in the cooling passage 44 can be adjusted by the air blowing device, so that the temperature at each portion of the hot-melt knife 41 can be more uniformly stabilized.

Specifically, the auxiliary mechanism 5 comprises a first compression roller 51, a second compression roller 52, a pressing plate 53, a first push rod motor 54, a second push rod motor 55, a first lifting frame 56, a second lifting frame 57 and an adjusting frame 58, wherein the first lifting frame 56 is in transmission connection with the first screw rod device 43, the first screw rod device 43 can drive the first lifting frame 56 to lift, the first push rod motor 54 is fixed on the first lifting frame 56, the adjusting frame 58 is connected with a push rod of the first push rod motor 54, the first compression roller 51 is rotatably arranged on the adjusting frame 58 and is positioned right above the hot melt knife 41, and the pressing plate 53 is fixed on the adjusting frame 58 and is arranged on one side of the first compression roller 51; the pressing plate 53 is gradually downward from the side near the first pressing roller 51 and is at least partially lower than the lowest position of the first pressing roller 51; the second push rod motor 55 is fixed on the moving frame 3, the second lifting frame 57 is fixed on the push rod of the second push rod motor 55, and the second press roller 52 is rotatably arranged on the second lifting frame 57 and is positioned right below the hot melt knife 41.

In this application, the heights of the first pressing roller 51 and the second pressing roller 52 are adjusted by the first push rod motor 54 and the second push rod motor 55 to ensure that the first pressing roller 51 and the second pressing roller 52 can be adjusted toward the sponge 100 and pressed against the sponge 100 after the hot melt knife 41 enters between the two layers of the sponge 100. In this way, the sponge 100 can be better attached to the hot melt knife 41. When the sponge 100 is contacted again after being melted, the sponge 100 is in a natural unstressed state, and the first press roller 51 and the second press roller 52 are not abutted. It is difficult to effectively bond the two sponges 100 by means of gravity alone. Thus, by applying pressure through the pressure plate 53, the two sponges 100 can be made to fit together better. The pressing plate 53 is located at the rear side of the first pressing roller 51 in the moving direction in the operating state of the moving frame 3. The working state refers to the time of hot melting the sponge. After the two sponges 100 are pressed and adhered, the pressing plate 53 is separated from the area, so that long-time pressing is avoided, and the hot melt adhesion part is collapsed and deformed.

In the present invention, the first pressing roller 51 and the second pressing roller 52 move following the hot-melt knife 41, and pressure is applied only at the position of the hot-melt knife 41, not to the whole sponge 100. This design allows the sponge 100 to be held against the site of the hot-melt knife 41 during the hot-melt process and to be pressed by the pressure plate 53 immediately after the hot-melt process is completed, thereby reducing the likelihood that the localized hot-melt site will have solidified and the extrusion will not be effective.

In the specific operation in this embodiment, the first push rod motor 54 drives the adjusting frame 58 to lift, the adjusting frame 58 drives the first press roller 51 and the pressing plate 53 to lift, the first press roller 51 is pressed on the upper layer sponge 100, the second push rod motor 55 drives the second lifting frame 57 to lift, the second lifting frame 57 drives the second press roller 52 to lift, and the second press roller 52 is pressed on the lower layer sponge 100 from bottom to top, so that the two layers of sponges 100 are attached towards the direction of the hot melt knife 41.

Specifically, a first driving motor is fixed on the first lifting frame 56, and is in transmission connection with the first press roller 51 for belt rotation, and a second driving motor is fixed on the second lifting frame 57, and is in rotation connection with the second press roller 52 for belt rotation.

By designing the first driving motor and the second driving motor, the first pressing roller 51 and the second pressing roller 52 can be made to move along the sponge 100. The situation of causing the position shift of the local sponge 100 occurs in the process of reducing and pressing.

Specifically, the surfaces of the first compression roller 51 and the second compression roller 52 are provided with anti-skid grains.

Can better fit the surface movement of the sponge 100.

Specifically, both ends of the pressing plate 53 are provided with arc-shaped scratch-preventing portions 531, and the free ends of the scratch-preventing portions 531 are disposed upward. Can be when the butt is on sponge 100, can not form to scratch sponge 100, better along the surface movement of sponge 100.

Specifically, the hot-melt knife comprises an abutting rod 6, the hot-melt knife 41 is in sliding fit in a mounting groove 421, the hot-melt knife 41 can horizontally move towards the inside of the mounting groove 421, a sliding hole 423 communicated with the mounting groove 421 is formed in a cross rod 42, a plurality of guide posts 413 are fixed on the hot-melt knife 41, and the guide posts 413 are inserted into the sliding hole 423 and in sliding fit, and the hot-melt knife 41 is connected to the inner wall of the mounting groove 421 through a spring 7; the upper and lower both sides of horizontal pole 42 are equipped with spacing groove 424, and the upper and lower both sides of horizontal pole 42 all are equipped with scraper 45, and the rear side of scraper 45 supports and leans on in spacing groove 424 and can swing around spacing groove 424, and the middle part of scraper 45 passes through extension spring 8 and is connected with horizontal pole 42 to make the edge of two scraper 45 support on the first heating surface 411 and the second heating surface 412 of hot melt sword 41, support the front side position that the pole 6 set up at the removal frame 3, hot melt sword 41 can support and lean on pole 6, so that hot melt sword 41 shrink in mounting groove 421.

In the present application, after the sponge 100 is melted by the heat-sealing knife 41, the melted partial material adheres to the heat-sealing knife 41, and the heat-sealing effect of the heat-sealing knife 41 at that position is reduced.

After the completion of the heat fusion, the heat fusion knife 41 is completely withdrawn from the layer of the sponge 100, and the complex mechanism 4 is moved to the front side between the abutment bars 6, so that the heat fusion knife 41 abuts against the abutment bars 6. Then, the moving frame 3 continues to move, and the hot-melt knife 41 gradually retracts into the mounting groove 421 upon receiving an external force. During retraction, the two scrapers 45 located on the upper and lower sides of the hot melt knife 41 gradually scrape off the adhering substances on the surface of the hot melt knife 41.

One end of the scraper 45 is abutted against the limit groove 424 of the cross bar 42, the scraper 45 can swing up and down relative to the limit groove 424, and the scraper 45 is connected with the cross bar 42 through the tension spring 8, so that the edge of the scraper 45 can be abutted against the hot-melt knife 41 all the time, and the scraper 45 can effectively move along the first heating surface 411 and the second heating surface 412 and scrape substances on the first heating surface 411 and the second heating surface 412. After scraping, the hot-melt knife 41 is moved away from the abutment lever 6, and the hot-melt knife 41 is returned by the spring 7 and protrudes from the mounting groove 421. Thereby rapidly removing the surface material of the hot melt knife 41 for the next use.

After the hot-melt knife 41 enters the mounting groove 421, the hot-melt knife 41 can be quickly cooled through the cooling channel 44, and meanwhile, in the working state, the components in the mounting groove 421 can be cooled, so that overheating damage is avoided. And after the temperature of the hot-melt knife 41 is reduced, the surface substances are easy to solidify, and the solidified substances are more easy to hang off in the subsequent scraping process of the scraper 45 on the surface of the hot-melt knife 41.

In the device there is also a frame on which the abutment bar 6 and the placement table 2 are fixed. The movable frame 3 moves horizontally with respect to the placement table 2, and the first and second lifting frames 56 and 57 are lifted with respect to the movable frame 3.
