Description

Technical Field

[0001] This utility model belongs to the field of wool composite knitted fabric processing technology, and in particular relates to a device for applying hot melt adhesive film to liquid ammonia mercerized wool composite knitted fabric. Background Technology

[0002] Wool composite knitted fabric is a type of knitted fabric made of wool. During its production, to achieve higher water resistance, a layer of hot-melt adhesive film is often applied to the fabric. This hot-melt adhesive film is hot-pressed onto the knitted fabric carrier, and after being heated and rolled, it melts and penetrates and solidifies within the pores of the knitted fabric carrier, thus increasing the waterproof properties of the composite fabric.

[0003] The prior art discloses a set of equipment specifically for producing this type of composite fabric, such as Figure 1 As shown, its main structure includes a fabric unwinding device for the knitted fabric carrier located at one end of the equipment, and a hot melt adhesive film unwinding device located at the opposite end of the equipment. The fabric unwinding device unwinds the fabric to one side, and the unwinding device unwinds the film to the opposite side. Finally, the two materials are passed through a composite device (hot pressing with electrically heated rollers). During the hot pressing process, the hot melt adhesive film melts and penetrates into the pores of the carrier fabric. Subsequently, the composite fabric heated by the rollers is cooled by a cooling device, and an edge-cutting device removes uneven edges and sucks out impurities. Then, it is fed through a traction device (roller traction) and finally wound up on a winding device.

[0004] The existing winding device disclosed in the technology includes a hinged arm with a reel mounted on it, on which the fabric is wound. The winding shaft adjusts the tension of the fabric during winding by rotating it with a cylinder. In this type of winding device, the reel rotates on one side of the hinged arm, making it suitable for processing lightweight and narrow fabrics. After winding is complete, the fabric is directly unloaded from the winding shaft.

[0005] In actual operation, the above structure is not suitable for winding thick and wide composite fabrics. This is because the roll structure requires a longer roll shaft. If the other side of the roll is not free-spinning, the stability is very poor, the roll shaft is prone to breakage, and there is severe shaking. In addition, the traditional double-headed rotating connection of the roll shaft cannot be flipped to adjust the angle of the roll structure, making it easier to tension the fabric.

[0006] Meanwhile, unloading is also difficult when processing heavy coiled materials. This is because the more turns the coiled material has, the larger its volume and weight. Currently, unloading relies on manual labor, which is not only difficult and laborious but also risky. Traditional unloading equipment, such as forklifts, cannot directly approach the processing equipment (due to the obstruction of the equipment frame space). Utility Model Content

[0007] Based on the above background, the purpose of this utility model is to provide a device for applying hot melt adhesive film to liquid ammonia mercerized wool composite knitted fabric.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A device for applying hot melt adhesive film to liquid ammonia mercerized wool composite knitted fabric includes an unwinding device for unwinding hot melt adhesive film, a fabric unwinding device for unwinding knitted fabric, and a composite device for hot-pressing and bonding the hot melt adhesive film and the knitted fabric. It also includes a winding mechanism for winding up the composite fabric.

[0010] The winding mechanism includes a frame located at the outlet end of the composite fabric, and a hinged winding assembly is installed on the frame. The winding assembly tensions the composite fabric by pushing the structure to rotate.

[0011] Both ends of the coil assembly are fixedly mounted on the hinged steel frame rods, which are hinged to the frame; the push structure is hinged to the steel frame rods.

The material unloading structure includes a track and a material unloading trolley that rolls on the track. The material unloading trolley is equipped with a support frame for supporting the rolled material.

[0014] Preferably, the frame includes steel structure supports spaced apart on both sides, and a number of pillow plates are fixedly installed at the bottom of the steel structure supports, with the pillow plates fixedly installed on the ground;

[0015] A track is installed on each of the top two sides of the pillow board.

[0016] Preferably, a steel frame rod is hinged to the inner side of each steel structure support;

[0017] One end of the steel frame pole is hinged to the steel structure support via a hinge structure;

[0018] The other end of the steel frame rod is hinged to the push structure.

[0019] Preferably, the hinge structure includes a hinge frame welded to one end of the steel frame rod, the hinge frame being hinged to a fixed mounting plate, and the fixed mounting plate being fixedly mounted on the steel structure support.

[0020] Preferably, the pushing structure includes a pushing cylinder that is hinged to a steel frame rod, a push rod that is fixedly mounted on the piston rod of the pushing cylinder, a U-shaped hinge seat that is fixedly connected to the push rod, a U-shaped fixed seat that is welded to the end of the steel frame rod, a hinge shaft that is welded to the U-shaped fixed seat, and the hinge shaft that is hinged to the U-shaped hinge seat.

[0021] The top of the cylinder of the push cylinder is hinged to a bracket structure, which is fixedly installed at the top of the steel structure support.

[0022] Preferably, a bearing bracket is fixedly installed on the top of each steel frame rod, and a rotating shaft is rotatably connected to each bearing bracket. The coil shaft is detachably installed on the rotating shaft through a flange structure.

[0023] A motor that drives the shaft to rotate is mounted on one side of the bearing bracket.

[0024] Preferably, the unloading trolley includes a frame, and a plurality of track rollers that roll on a track are fixedly installed at the bottom of the frame;

[0025] A pair of spaced-apart support brackets are fixedly connected to the top of the frame.

[0026] Preferably, the support bracket includes a V-shaped bracket for supporting the roll shaft, and the bottom of the V-shaped bracket is fixedly installed at the top position of the vehicle frame by a support rod.

[0027] Preferably, a hook is fixedly connected to the bottom of the frame, the hook is attached to the unloading steel rope, and the unloading steel rope is wound around the unloading winch.

[0028] This utility model has the following beneficial effects:

[0029] 1. This utility model uses two high-strength steel frame rods to mount the roll shaft, enabling the heavy roll device to be flipped and stretched to tighten the fabric.

[0041] Example 1

[0042] like Figure 1-5As shown, a device for applying hot melt adhesive film to liquid ammonia mercerized wool composite knitted fabric has the same main structure as existing production line equipment for producing composite fabrics of the same material. It mainly includes a fabric unwinding device for the knitted fabric carrier located at the left end of the production line equipment, and a film unwinding device for the hot melt adhesive film located at the right end of the production line equipment. The fabric unwinding device unwinds the fabric to the right, and the film unwinding device unwinds the film to the left. Finally, the two materials are passed through a composite device (hot-pressed by electrically heated rollers). During the hot-pressing process, the hot melt adhesive film melts and penetrates into the pores of the carrier fabric. The roller-heated composite fabric is then cooled by cooling equipment on the production line, and after the edges are cut off by a cutting and edge-removing device, and impurities are sucked out, it is fed through a traction device (roller traction) and finally wound up on a winding device.

[0043] The fabric feeding device, unwinding device, composite device, and cutting edge suction device in the above-mentioned production line equipment are all common devices on existing production lines for wool composite knitted fabrics. Those skilled in the art can learn about the specific working principles and mechanical structures of the above-mentioned devices on existing production lines by consulting technical manuals and dictionaries.

[0044] Based on the existing production line equipment, this utility model improves the winding device for winding composite fabrics to solve the technical defects of existing winding mechanisms that cannot smoothly and efficiently wind composite fabrics with large thickness, width, weight, and volume in actual production processes.

[0045] Specifically, the aforementioned device also includes a winding mechanism for winding the composite fabric; the winding mechanism is located at the discharge end of the production line equipment.

[0046] Specifically, the winding mechanism includes a frame positioned at the outlet end of the composite fabric. The frame includes steel structure supports 1 (reinforced steel frames) spaced apart on both sides. Several pillow plates 11 are fixedly installed at the bottom of the steel structure supports 1, which are conventionally fixed to the ground. During operation, the frame of the winding mechanism is directly installed at the outlet end of the composite fabric to wind up the composite fabric fed by the receiving rollers.

[0047] The frame is equipped with a hinged roll assembly 2, which tensions the composite fabric by pushing the structure to rotate.

[0048] Both ends of the coil assembly 2 are fixedly mounted on the hinged steel frame rod 21, which is hinged to the frame. The push structure is hinged to the steel frame rod 21. The coil assembly 2 includes a detachably mounted coil shaft 24 and a motor that drives the coil shaft 24 to rotate.

[0049] Specifically, this utility model uses a roll shaft 24 of a certain length to wind up the fabric with the above-mentioned characteristics. In order to ensure the stability of the winding process, the roll shaft 24 is set with a double-end rotating connection. In order to solve the problem of tensioning the fabric during the winding process, the roll shaft 24 with the double-end rotating connection is hinged and flipped. That is, when the fabric is loose, the roll shaft 24 can be flipped downwards to tension the fabric.

[0050] Specifically, a steel frame rod 21 is hinged to the inner side of the steel structure support 1 on both the left and right sides; the hinge method is as follows:

[0051] The rear end of the steel frame pole 21 is hinged to the steel structure support 1 via a hinge structure. Specifically, the hinge structure includes a hinge frame (U-shaped structure) welded to the rear end of the steel frame pole 21. The hinge frame is hinged to a fixed mounting plate 211 (same as in the existing method, a hinge shaft is welded to the hinge frame, and the hinge shaft is rotatably connected to a bearing on the fixed mounting plate 211). The fixed mounting plate 211 is fixedly mounted to the steel structure support 1 by bolts.

[0052] Meanwhile, the front end of the steel frame rod 21 is hinged to the pushing structure. Specifically, the pushing structure includes a pushing cylinder 25 that is hinged to the steel frame rod 21. A push rod 251 is fixedly mounted on the piston rod of the pushing cylinder 25, and a U-shaped hinge seat is fixedly connected to the push rod 251. Correspondingly, a U-shaped fixing seat 212 is welded to the end of the steel frame rod 21, and a hinge shaft 2121 is welded to the U-shaped fixing seat 212. The hinge shaft 2121 is hinged to the U-shaped hinge seat.

[0053] In the same way as the existing cylinder hinge installation method, the top of the cylinder barrel of the push cylinder 25 is hinged to a bracket structure, which is fixedly installed at the top of the steel structure bracket 1.

[0054] Specifically, a hinge plate is fixed to the top of the cylinder barrel, and the hinge plate is hinged to the support structure. When it is necessary to tension the composite fabric, the cylinders on both sides simultaneously push the steel frame rod 21 to flip downwards. During this process, the roll shaft 24, which is installed between the steel frame rods 21 and rotates at both ends, pulls the fabric downwards and tensions the fabric.

[0055] The advantages of this structure are as follows: Firstly, traditional double-ended rotating connection roll shafts 24 are mostly fixedly installed, requiring an additional tensioning structure to be installed to tension the fabric. The above-mentioned technical solution, however, uses two high-strength steel frame rods 21 to mount the roll shaft 24, enabling the bulky roll device to be flipped and pulled to tension the fabric.

[0056] Therefore, the above technical solution solves the problem of winding thick composite fabrics with large volume and weight after winding, while also addressing the issue of adaptive fabric tensioning during the winding process. It fundamentally overcomes the technical shortcomings of traditional reels (driven by a motor, with a single-sided rotating connection) in winding wide and heavy fabrics.

[0057] Example 2

[0058] like Figure 1-5 As shown, in this embodiment, based on the structure of Embodiment 1, bearing brackets 23 are fixedly installed on the top of the steel frame rods 21, in the same manner as existing rotating connections. Rotating shafts are rotatably connected to the bearing brackets 23, and the coil shaft 24 is detachably mounted on the rotating shafts via a flange structure. Similar to existing motor 22 driving the rotating shafts, a motor 22 for driving the rotating shafts is installed on the left bearing bracket 23. Also similar to existing motor installation methods, the bottom of the motor 22 is mounted on the bearing brackets 23 via a motor mounting bracket.

[0059] Example 3

[0060] like Figure 1-5 As shown, this embodiment is based on the structure of embodiment 2. Because the above structure has a large weight and volume of thickened composite fabric, in order to facilitate unloading and improve unloading efficiency, the above structure also includes an unloading structure 3 set at the lower end of the frame. The unloading structure 3 includes a track 31 and an unloading trolley that rolls on the track 31. The unloading trolley is equipped with a support frame for supporting the roll.

[0061] Specifically, a track 31 is installed on each of the top two sides of the pillow plate. The unloading trolley includes a frame 32, and several track 31 rollers that roll on the track 31 are fixedly installed at the bottom of the frame 32 (similar to the existing limited rolling method, the track 31 rollers roll in the track 31 groove on the track 31 in an anti-detachment manner); a pair of spaced-apart support brackets are fixedly connected to the top of the frame 32.

[0062] Specifically, the support bracket includes a V-shaped bracket 33 that supports the coil shaft 24, and the bottom of the V-shaped bracket 33 is fixedly installed at the top of the frame 32 by a support rod.

[0063] During operation, after the material is wound on the coil 24, the operator disassembles the flange structure, lowers both ends of the coil 24 and supports them on the V-shaped bracket 33, and then drags the unloading trolley along the track 31 to transfer it. The idle coil 24 is then reinstalled through the flange structure 241 (the flange structure is as follows: a female flange seat is fixed on the coil 24, and a female flange seat is fixed on the rotating shaft. The two are connected by bolts).

[0064] In actual operation, a more convenient method can also be used to install the coil shaft 24, such as directly fixing the coil shaft 24 to the rotating shaft with a pin (another way to disassemble the coil is to mount the end of the coil shaft 24 onto the bushing welded on the rotating shaft, and after the pin passes through the coil shaft 24, the nut is locked. When disassembling, simply loosen the nut and remove the coil shaft 24 from the bushing).

[0065] To facilitate the removal of the heavy coiled material loaded on the frame 32 from the machine frame, a hook-up ring 321 is fixedly connected to the bottom of the frame 32. In existing material removal methods, the hook-up ring is attached to a discharge steel rope (not shown in the figure), which is wound around a discharge winch (not shown in the figure). The discharge winch is a conventional winch disclosed in the prior art, and the coiled material is unloaded by towing it.

[0066] Example 4

[0067] like Figure 1-5 As shown, based on the structure of Example 3, in order to further save effort in actual operation, the V-shaped bracket can be installed hydraulically. For example, a jack can be installed at the bottom of the V-shaped bracket, and the unloading can be completed by directly lifting the coil-coil shaft 24 structure through the hydraulic jack.

[0068] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
