Description

Technical Field

[0001] This utility model belongs to the field of hot pressing technology of materials, and specifically relates to a device for hot pressing and bonding of materials. Background Technology

[0002] In existing technical solutions, roller hot pressing is used to bond hot melt adhesive materials, which achieves the bonding effect between the material to be bonded and the hot melt adhesive material. However, for roller hot pressing, the contact area between the heating surface and the heated material is small, which cannot guarantee the heating time of the hot melt material. In addition, the pressure during heating is not uniform, which leads to delamination, hollowing, or poor bonding after hot bonding.

[0003] Therefore, it is necessary to design a device for hot pressing and bonding of materials to solve the technical problem in the existing technology where the hot melt material is subjected to pressure for a short time during the roller hot pressing process, resulting in incomplete hot bonding and thus poor bonding of the final material.

[0004] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present application concept, and therefore, the above description is not considered to constitute prior art information. Utility Model Content

[0056] Research has found that in existing technical solutions, roller hot pressing is used to bond hot melt adhesive materials. This achieves the bonding effect between the material to be bonded and the hot melt adhesive material. However, with roller hot pressing, the contact area between the heating surface and the heated material is small, which cannot guarantee the heating time of the hot melt material. In addition, the pressure during heating is not uniform, which leads to delamination, hollowing, or poor bonding after hot bonding.

[0057] Based on the above research, this disclosure provides an apparatus for hot pressing and bonding materials. By setting a reciprocating stepping material pulling mechanism, it can replace manual material pulling and has more precise material pulling distance control compared with roller winding machine. The heating and bonding effect is better, and it reduces delamination, hollowing or poor bonding caused by uneven heating or uneven pressure, thereby reducing the product defect rate.

[0058] The shortcomings of the above solutions are the result of the inventor's practical experience and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure should be considered as the inventor's contribution to this disclosure.

[0059] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0060] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0061] In some embodiments, such as Figure 1 and Figure 2 As shown, at the beginning of the initial hot-melt process, the first end of the material strip is placed on the upper surface of the lower heating platform 5. The driver 1 is started, and its output end drives the upper heating platform 3 to move towards the lower heating platform 5 until the two are in contact and clamp the material strip. By clamping and heating the material strip, the hot melt adhesive on the material strip melts and adheres to the material on the material strip. After clamping and heating is completed, the driver 1 drives the upper heating platform 3 to move upward. Then, the operator manually pulls the first end of the material strip after hot melting into the reciprocating stepping material pulling mechanism 4. The reciprocating stepping material pulling mechanism 4 clamps the first end of the material strip and pulls the material strip to move a distance (this distance is the same as the length of the upper heating platform 3 or the lower heating platform 5). Then, the driver 1 is started again to move the upper heating platform 3 downward. The above steps are repeated to continuously heat the material strip.

[0062] In some embodiments, such as Figure 2As shown, a control box 9 is fixed on one side of the bracket 2. The control box 9 integrates functions such as temperature control of the upper and lower heating platforms, operation indicator lights, operation time and frequency adjustment of the driver 1, and pressure adjustment of the driver 1. When the safety light curtain sensors 7 on both sides of the lower heating platform 5 detect an object, they will stop all moving mechanisms of the equipment and return to a safe state. In addition, a start / stop button 8 is fixed on one side of the base 6 to manually stop the equipment in case of an emergency (the above functions are all existing technologies and will not be described in detail here).

[0063] In some embodiments, Figure 3 and Figure 4 The diagram shows the movement of the upper heating platform 3. The lower heating platform 5 is naturally attached to the material belt. The upper heating platform 3 is pushed down and tightly attached to the material belt by the driver 1. The upper and lower heating platforms completely clamp the material belt and control the downward pressure by the driver 1. After the heating time is met, the upper heating platform 3 moves up and returns to the initial position.

[0064] In some embodiments, such as Figure 5 As shown, the connecting base 54 of the lower heating platform 5 is fixed to the upper end face of the heating base 6. Before the material strip is melted, the electric heating tube 51 is energized to make it heat up, which in turn makes the heating plate 52 heat up. The heating plate 52 is made of brass, which has good thermal conductivity. The heating plate 52 has holes on its side so that the electric heating tube 51 can be embedded in the holes and the side wall is completely fitted, so that the heating plate 52 is heated evenly. The heat insulation plate 53 is a flame-retardant heat insulation material, which isolates the heat of the heating plate 52 from the fixed base 54. The structure of the upper heating platform 3 is the same as that of the lower heating platform 5, and the heating plates on the two heating platforms are arranged opposite each other.

[0065] In some embodiments, such as Figure 6 and Figure 7 As shown, after being clamped and heated by the upper and lower heating platforms, the material strip moves under the C-shaped fixing member and onto the upper surface of the pulling platform 42. At this time, the second drive cylinder is activated, driving the pressure holding member 41 to move down and clamp the material strip again. After the pressure holding member 41 is tightly attached to the material strip, the first drive cylinder is activated, pushing the pulling platform 42 to move along the guide direction of the slide rail 43, simultaneously pulling the material strip. After the pulling platform 42 has moved a certain distance, the second drive cylinder drives the pressure holding member 41 to move up, and the first drive cylinder simultaneously drives the pulling platform 42 to reset. For the material strip, after its first end is reprocessed, it can be pulled out and wound up by the operator to avoid the material strip moving in the opposite direction due to the resetting of the pulling platform 42. The movement process of the pressure holding member 41 and the pulling platform 42 is as follows. Figure 8 and Figure 9 As shown.

[0066] In summary, by employing upper and lower heating platforms for clamping and heating of the material strip, and by incorporating a reciprocating stepping material pulling mechanism, manual material pulling can be replaced. Compared to roller winding machines, it offers more precise material pulling distance control. Furthermore, by utilizing pressure-holding components, the heated material strip is kept clamped and adhered during movement, reducing issues such as delamination, hollow areas, or poor adhesion caused by uneven heating or pressure, thereby lowering the product defect rate.

[0067] In the description of the embodiments of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0068] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence unless expressly indicated herein. Therefore, without departing from the teachings of the exemplary embodiments, the first element, component, region, layer, or segment discussed above may be referred to as the second element, component, region, layer, or segment.

[0069] Spatially relative terms, such as “inside,” “outside,” “below,” “below,” “down,” “above,” “up,” etc., may be used herein to describe the relationship between one element or feature illustrated in the figures and another element or feature. In addition to the orientations depicted in the figures, spatially relative terms may be intended to cover different orientations of the device in use or operation. For example, if the device in the figure is flipped, an element described as “below” or “below” other elements or features would be oriented as “above” other elements or features. Thus, the example term “below” can cover both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or in other orientations), and the spatially relative descriptors used herein are interpreted accordingly.

[0070] In the above discussion, unless otherwise stated, when used to describe numerical values, the terms “about,” “approximately,” “basically,” etc., indicate a change of + / - 10% in that value.

[0071] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
