For example, in the apparel industry, it can be used to laminate fabrics with linings, insulation layers, etc., to enhance the functionality and texture of clothing; in home décor, it is used to produce composite fabrics such as sofa upholstery and curtains.

[0003] Existing fabric laminating machines use roller pressing to laminate two or more layers of fabric together. After lamination, a drying device is needed to dry the fabric to increase the tightness between the layers.

[0004] This type of fabric lamination equipment requires the construction of a long production line, plus drying equipment for auxiliary processing, which not only results in high costs for enterprises but also low work efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a heated double-sided laminating machine that can dry the adhesive between fabric layers during fabric lamination, directly improving the tightness of the fabric lamination, and eliminating the need for a drying device. This reduces the length of the production line, saves space, lowers production costs, and improves work efficiency, thereby solving the technical problems mentioned in the background.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A heated double-sided laminating machine, comprising

[0008] A bonding apparatus having a first pressing mechanism for bonding a first bonding roll and an incoming material, and a second pressing mechanism for bonding a second bonding roll and an incoming material.

[0009] The first pressing mechanism and the second pressing mechanism have the same structure, both including a hanger for mounting the upper heating roller. The two ends of the hanger are fixed to the cylinder rods of two adjusting cylinders respectively. The upper end of the adjusting cylinder is fixed to the inside of the machine frame through the cylinder seat. A lower heating roller is provided below the upper heating roller. The two ends of the lower heating roller are mounted on the inside of the machine frame through bearings.

[0010] Both the upper heating roller and the lower heating roller are composed of a roller and a roller core, wherein the outer surface of the roller core is provided with multiple spiral grooves with a semi-circular cross section.

[0011] As a further technical solution of this utility model, one end of the roller is closed, and the other end is threadedly connected to an end cap. An inlet pipe is welded to the outside of the end cap, and multiple diversion pipes are arranged in a ring along the axis of the inlet pipe; the diversion pipes extend to the inside of the end cap.

[0012] As a further technical solution of this utility model, it also includes a heat transfer oil heating device, which includes a supply pipe and a return pipe for supplying and returning oil to the upper heating roller and the lower heating roller; wherein the supply pipe is connected to the heating cylinder, and the return pipe is connected to the inlet end of the circulating pump group; the outlet end of the circulating pump group is connected to the heating cylinder.

[0013] As a further technical solution of this utility model, at least one heating cylinder is provided, and a heater is installed inside the heating cylinder.

[0014] As a further technical solution of this utility model, the liquid supply pipe is connected to an exhaust pipe via a three-way valve, and the other end of the exhaust pipe is connected to the oil storage tank.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. In this utility model, the heat transfer oil is circulated under the operation of the circulating pump group. The heat transfer oil is first transported to the heating cylinder and heated by the heater. Then it is supplied to the upper heating roller and the lower heating roller through the liquid supply pipe. Subsequently, it returns to the circulating pump group through the liquid return pipe, thereby realizing the circulating heating of the heat transfer oil. This can ensure the temperature requirements of the fabric during the lamination process.

[0019] 2. In this invention, some gases are generated during the circulation of heat transfer oil, which may lead to poor heat transfer effect. By setting an exhaust pipe, the internal gases can be released, thereby ensuring the heating effect of the heat transfer oil.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Please see Figure 1-8 In this embodiment of the utility model, a heating double-sided laminating machine is provided, and a laminating device 100 is provided. The laminating device 100 has a first pressing mechanism 3 for laminating a first laminating roll 2 and the incoming material, and a second pressing mechanism 5 for laminating a second laminating roll 4 and the incoming material.

[0035] The inner side of the frame body 1 is provided with a first unwinding shaft and a second unwinding shaft. The first material roll 2 is installed on the first unwinding shaft, and the second material roll 4 is installed on the second unwinding shaft. One end of each unwinding shaft is suspended, and the other end is connected to the frame body 1 through a bearing.

[0036] A slitting assembly 6 is also installed on the outside of the second pressing mechanism 5. The slitting assembly 6 consists of an upper slitting roller and a lower slitting roller. The upper slitting roller and the lower slitting roller are connected by two meshing gears, and a drive motor is also connected to the outside of the lower slitting roller.

[0037] Inside the frame 1, a first take-up roller 7, a second take-up roller 8, and an edge take-up roller 9 are also installed. Each take-up roller is installed in conjunction with the frame via a bearing and is also equipped with a drive motor.

[0038] By adopting the above technical solution, when external materials arrive, they enter the first pressing mechanism 3, where the first adhesive roll 2 with adhesive on one side is unfolded and bonded to the incoming material, and the bonding is performed by the first pressing mechanism 3. After bonding, it enters the second pressing mechanism 5, where the second adhesive roll 4 with adhesive on one side is bonded to the incoming material, and the bonding is performed by the second pressing mechanism 5. After bonding, it enters the slitting assembly 6 for slitting. The slitting fabric is then wound up by the first take-up roller 7 and the second take-up roller 8, and the excess edge material is wound up by the excess edge take-up roller 9. This equipment can realize the functions of double-sided bonding, slitting, and winding of fabric without the need for excessive equipment, which greatly reduces the production cost of enterprises and improves work efficiency.

[0039] The first pressing mechanism 3 and the second pressing mechanism 5 adopt the same structure, both including a hanger 11 for mounting the upper heating roller 12. The two ends of the hanger 11 are respectively fixed to the cylinder rods of two adjusting cylinders 10. The upper end of the adjusting cylinder 10 is fixed to the inner side of the frame body 1 through the cylinder seat. A lower heating roller 13 is provided below the upper heating roller 12. The two ends of the lower heating roller 13 are mounted on the inner side of the frame body 1 through bearings.

[0040] By adopting the above technical solution, when the fabric is laminated, the adjusting cylinder 10 can adjust the hanging frame 11 up and down by retracting the cylinder rod, thereby adjusting the pressure between the upper heating pressure roller 12 and the lower heating pressure roller 13. This is suitable for adjusting fabrics of different thicknesses and composite pressure requirements, thereby meeting the composite pressure requirements of the fabric.

[0041] In this embodiment, both the upper heating roller 12 and the lower heating roller 13 are composed of a roller 121 and a roller core 122, wherein the outer surface of the roller core 122 is provided with a plurality of spiral grooves with a semi-circular cross section.

[0042] One end of the roller 121 is closed and welded with a round tube for connecting to a rotary joint; the other end is threaded with an end cap 123, and an inlet pipe 125 is welded to the outside of the end cap 123 for connecting to the rotary joint; the inlet pipe 125 is not connected to the end cap 123; a plurality of diversion pipes 124 are arranged in a ring along the axis of the inlet pipe 125; the diversion pipes 124 extend to the inside of the end cap 123.

[0043] By adopting the above technical solution, the heat transfer oil supplied by the liquid supply pipe 27 enters the liquid inlet pipe 125, and then is distributed to the inside of the end cap 123 through multiple diversion pipes 124. Each diversion pipe 124 corresponds to a spiral groove, so as to facilitate the transfer of heat transfer oil into the spiral groove.

[0044] Some conventional heating rollers are hollow inside, which requires a large amount of heat transfer oil. This results in poor heat transfer oil circulation. Especially for fabric lamination with strict temperature control requirements, the heat transfer oil accumulates inside the heating roller and cannot circulate quickly, causing the temperature to fluctuate and making it impossible to ensure the quality of fabric lamination.

[0045] By using a spiral design to distribute the heat transfer oil, the amount of heat transfer oil used can be reduced, and a rapid circulation effect can be achieved. Furthermore, the spiral grooves can cover the entire inner surface of the roller 121, thereby meeting the composite temperature requirements of the fabric.

[0046] In addition, the amount of heat transfer oil in the spiral groove is small, and it can be discharged quickly during circulation, so that the temperature of the heat transfer oil can be changed according to the fabric condition.

[0047] In this embodiment, a heat transfer oil heating device 200 is also included. The heat transfer oil heating device 200 includes a supply pipe 27 and a return pipe 23 for supplying and returning oil to the upper heating roller 12 and the lower heating roller 13. The supply pipe 27 is connected to the heating cylinder 25, and the return pipe 23 is connected to the inlet end of the circulating pump group 22. The outlet end of the circulating pump group 22 is connected to the heating cylinder 25.

[0048] Furthermore, the supply pipe 27 and return pipe 23 can be diverted through multi-port connectors to ensure the supply and return of oil for multiple upper heating rollers 12 and lower heating rollers 13. The diversion method through multi-port connectors is a conventional technical means, so it will not be described in detail here.

[0049] In this embodiment, at least one heating cylinder 25 is provided, and a heater 26 is installed inside the heating cylinder 25. The heater 26 is electrically connected to an external temperature controller (not shown), and the heater 26 heats the heat-conducting oil inside the heating cylinder 25 to provide a suitable temperature for the upper heating roller 12 and the lower heating roller 13 to achieve adhesive drying during fabric lamination.

[0050] By adopting the above technical solution, the heat transfer oil is circulated under the operation of the circulating pump group 22. The heat transfer oil is first transported into the heating cylinder 25 and heated by the heater 26. Then it is supplied to the upper heating roller 12 and the lower heating roller 13 through the liquid supply pipe 27. Subsequently, it returns to the circulating pump group 22 through the liquid return pipe 23, thereby realizing the circulating heating of the heat transfer oil. This can ensure the temperature requirements of the fabric during the lamination process.

[0051] In this embodiment, the supply pipe 27 is connected to the exhaust pipe 28 via a three-way valve, and the other end of the exhaust pipe 28 is connected to the oil storage tank 29.

[0052] By adopting the above technical solution, some gas will be generated during the heat transfer oil circulation process. This gas may lead to poor heat transfer effect. By setting the exhaust pipe 28, the internal gas can be released, thereby ensuring the heating effect of the heat transfer oil.

[0053] Releasing high-temperature gas into the oil storage tank 29 can preheat the heat transfer oil inside the oil storage tank 29. When the heat transfer oil enters the return pipe 23, it can reduce the heating time, reduce the power consumption of the heater 26, and achieve the effect of energy saving.

[0054] In this embodiment, the return pipe 23 is connected to the replenishment pipe 211 via a three-way valve, and the upper end of the replenishment pipe 211 is connected to the bottom of the oil storage tank 29.

[0055] By adopting the above technical solution, the heat transfer oil in the oil storage tank 29 enters the return pipe 23 through the replenishment pipe 211, thereby ensuring that there is enough heat transfer oil to participate in the circulation.

[0056] In this embodiment, the oil storage tank 29 is fixed to the top of the casing 21 by a bracket, and a liquid addition funnel 210 is connected to one side of the oil storage tank 29. Heat transfer oil can be added to the oil storage tank 29 through the liquid addition funnel 210 for later use.

[0057] The working principle of this utility model is as follows: When the fabric is laminated, the adjusting cylinder 10 can adjust the hanging frame 11 up and down by retracting the cylinder rod, thereby adjusting the pressure between the upper heating roller 12 and the lower heating roller 13. This is suitable for adjusting fabrics of different thicknesses and composite pressure requirements, thus meeting the composite pressure requirements of the fabric. The heat transfer oil is circulated under the operation of the circulating pump group 22. The heat transfer oil is first delivered to the heating cylinder 25 and heated by the heater 26. Then it is supplied to the upper heating roller 12 and the lower heating roller 13 through the liquid supply pipe 27, and then returned to the circulating pump group 22 through the liquid return pipe 23, thereby realizing the circulating heating of the heat transfer oil. This ensures the temperature requirements of the fabric during lamination.

[0058] During the oil supply process to the upper heating roller 12 and the lower heating roller 13, the heat-conducting oil supplied by the liquid supply pipe 27 enters the liquid inlet pipe 125, and then is distributed to the inside of the end cap 123 through multiple diversion pipes 124. Each diversion pipe 124 corresponds to a spiral groove, so as to facilitate the transfer of heat-conducting oil into the spiral groove. By diverting and transferring heat-conducting oil by opening a spiral line, the amount of heat-conducting oil used can be reduced, and a rapid circulation effect can be achieved. Moreover, the spiral grooves set by the spiral can cover the entire inner surface of the roller 121, thereby meeting the composite temperature requirements of the fabric.

[0059] In addition, the amount of heat transfer oil in the spiral groove is small, and it can be discharged quickly during circulation, so that the temperature of the heat transfer oil can be changed according to the fabric condition.

[0060] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0061] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style of the specification is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
