Description

Technical Field

[0001] The present application relates to the field of gluing machines, and in particular to a pre-unwinding buffer device for gluing equipment. Background Art

[0002] In order to improve the service life and quality of leather, it is usually necessary to apply glue to the leather surface. Gluing is a process in which glue (including solvent glue, latex and water glue) is evenly applied to the surface of the fabric through glue coating equipment.

[0003] In the prior art, common gluing equipment primarily consists of a frame, on which are mounted an unwinding mechanism, a tension control mechanism, a rewinding mechanism, a gluing mechanism, and a cooling and drying mechanism. The unwinding mechanism unwinds the raw material coil at a constant speed. The coil is then driven by the tension control mechanism and passes through the gluing mechanism. After the coated coil is delivered by the gluing mechanism, the cooling and drying mechanism cools the coil to dry the adhesive on the coil surface. The dried coil is then rewound by the rewinding mechanism.

[0004] However, in the actual production and processing process, when the existing gluing equipment is exhausted and needs to be replenished on the unwinding mechanism, it is often necessary to stop the machine to replenish and bond the rolls, which affects production efficiency and needs improvement. Utility Model Content

[0005] In order to facilitate operators to replenish rolls without stopping the machine and improve the processing efficiency of the gluing equipment, the present application provides a front-end unwinding buffer device for the gluing equipment.

[0006] The present application provides a pre-unwinding buffer device for a gluing device that adopts the following technical solution:

[0007] A front unwinding buffer device for a gluing device comprises a buffer bracket located between a roll-out mechanism and a gluing mechanism, two mounting side plates being fixedly mounted on the buffer bracket, a plurality of first pulling rollers being mounted between the two mounting side plates, and two ends of the plurality of first pulling rollers being rotatably mounted on the two mounting side plates;

[0008] The inner side walls of the two mounting side plates are respectively provided with connecting plates that can be raised and lowered, and a plurality of second pulling rollers are installed between the two connecting plates. Both ends of the plurality of second pulling rollers are respectively rotatably installed on the two connecting plates, and the plurality of second pulling rollers are respectively staggeredly arranged between two adjacent first pulling rollers.

[0009] The mounting side plate is provided with a driving mechanism for simultaneously moving the two connecting plates toward or away from the first pulling rollers.

[0010] By adopting the above technical solution, during the actual production process, a portion of the coil can be wound and cached in the cache holder via the first and second pulling rollers. When the coil on the unwinding mechanism is exhausted, the operator can install a new coil on the unwinding mechanism and affix the new coil to the coil in the cache holder, eliminating the need to stop the machine for restocking and improving the production efficiency of the gluing equipment. In addition, because the connecting plate on which the second pulling roller is mounted can be moved toward or away from the first pulling roller by the drive mechanism, the height of the second pulling roller can be adjusted, making it easier for the operator to adjust the cache holder to adjust the coil cache capacity as needed.

[0011] Preferably, the driving mechanism includes a first shaft, two first chains and two driving members, the two ends of the first shaft are rotatably mounted on the two mounting side plates, and one end of the first shaft passing through the two mounting side plates is fixedly mounted with a driving sprocket, two sets of transmission sprocket groups are rotatably mounted on the outer side walls of the two mounting side plates, and the two first chains are respectively sleeved on the two driving sprockets and the two sets of transmission sprocket groups;

[0012] A first adjusting sprocket is fixedly mounted on both ends of the first shaft, and the two first adjusting sprockets are located on the inner sides of the two mounting side plates. Two second adjusting sprockets are rotatably mounted on the inner side walls of the two mounting side plates. The two second adjusting sprockets are located below the two first adjusting sprockets, and second chains are sleeved on the opposite first adjusting sprockets and second adjusting sprockets. The two connecting plates are fixedly connected to the two second chains respectively.

[0013] The two driving members are respectively fixedly mounted on the outer side walls of the two mounting side plates, and the driving ends of the two driving members are respectively fixedly connected to the two first chains, and the two driving members simultaneously drive the two chains to move in the same direction.

[0014] By adopting the above technical solution, the driving member drives the first chain to move in different directions. The movement of the first chain can drive the first shaft to rotate through the driving sprocket, and then drive the first adjusting sprocket on the first shaft to rotate, so that the first chain installed on the first adjusting sprocket and the second adjusting sprocket moves. Since the two connecting plates are fixedly installed on the connecting plates, the two connecting plates on which the second traction roller is installed can be driven to rise or fall at the same time, thereby achieving the technical effect of adjusting the height of the second traction roller and adjusting the cache amount of the coiled material by the cache bracket.

[0015] Preferably, the driving member includes a telescopic cylinder, the cylinder bodies of the two telescopic cylinders are respectively fixedly mounted on the outer side walls of the two mounting side plates, and the cylinder shaft ends of the two telescopic cylinders are respectively fixedly connected to the two first chains.

[0016] By adopting the above technical solution, the telescopic cylinder extends or retracts the cylinder shaft to drive the first chain to move in different directions. The transmission sprocket group can synchronously drive the first shaft rod and the first adjustment sprocket to rotate, and then the second chain rotates to drive the two connecting plates to rise and fall.

[0017] Preferably, a second shaft is installed between the two mounting side plates, the second shaft is located directly below the first shaft, and both ends of the second shaft are rotatably connected to the two mounting side plates respectively, and the two second adjustment sprockets are fixedly mounted on the second shaft.

[0018] By adopting the above technical solution, the installation of the two second adjusting sprockets can be achieved through the second shaft.

[0019] Preferably, two guide rods are fixedly installed on the inner side walls of the two mounting side plates, and sliders are fixedly installed on the two connecting plates. The sliders are respectively provided with sliding holes adapted to the guide rods, and the sliders are slidably arranged on the guide rods.

[0020] By adopting the above technical solution, the guide rod can limit the sliding trajectory of the two connecting plates, reduce the shaking and deviation of the two connecting plates and the second traction rollers between the two connecting plates during the lifting process, and improve the stability of the lifting and lowering movements of the two connecting plates and the second traction rollers between the two connecting plates.

[0021] Preferably, a mounting top plate and a mounting bottom plate are fixedly mounted on the inner side wall of the mounting side plate, and both ends of the guide rod are fixedly connected to the mounting top plate and the mounting bottom plate respectively;

[0022] A spring is fixedly mounted on the mounting base plate, and the spring is coaxially sleeved on the guide rod.

[0023] By adopting the above technical solution, the spring can limit the lowest position of the connecting plate. At the same time, when the slider on the connecting plate is against the spring and the telescopic cylinder drives the connecting plate to move up, the spring recovery can form an upward elastic force on the connecting plate, thereby accelerating the resetting of the connecting plate.

[0024] Preferably, a sealing plate is fixedly installed between the two mounting side plates, and a discharge port for delivering the coil is formed at the bottom of the sealing plate;

[0025] An inspection platform is fixedly installed on the ground between the sealing plate and the gluing mechanism. The inspection platform is erected above the material discharge port. A passage for the coil to flow is opened through the inspection platform.

[0026] By adopting the above technical solution, the sealing plate can protect the leather material. After the leather material is sent out through the discharge port at the bottom of the sealing plate, it can be transported to the gluing mechanism through the channel under the maintenance platform for gluing processing. When the gluing equipment needs to be repaired, the maintenance personnel can stand on the maintenance platform to repair and maintain the gluing equipment, which can improve the convenience of maintenance and repair operations on the gluing equipment.

[0027] In summary, the pre-unwinding buffer device for gluing equipment of the present application has at least one of the following beneficial technical effects:

[0028] 1. During the actual production process, part of the coil can be wound and cached in the cache holder through the first and second pulling rollers. When the coil on the unwinding mechanism is exhausted, the operator can install a new coil on the unwinding mechanism and glue the new coil to the coil in the cache holder. This can avoid the need to stop the machine to replenish the coil, thereby improving the production efficiency of the gluing equipment.

[0029] 2. Since the connecting plate on which the second pulling roller is installed is driven by the driving mechanism to move toward or away from the first pulling roller, the height of the second pulling roller can be adjusted, making it convenient for the operator to adjust the buffering amount of the coil by adjusting the buffer bracket as needed.

[0033] The following is combined with Figure 1-2 This application is described in further detail.

[0034] Example

[0035] The embodiment of the present application discloses a pre-rolling buffer device for a gluing device. Figure 1 and Figure 2It mainly includes a cache bracket 3 located between the unwinding mechanism 1 and the gluing mechanism 2, two mounting side plates 31 are fixedly installed on the cache bracket 3, a number of first pulling rollers 4 are installed between the two mounting side plates 31, and the two ends of the first pulling rollers 4 are rotatably installed on the two mounting side plates 31; connecting plates 32 are respectively provided on the inner side walls of the two mounting side plates 31, which can be raised and lowered and adjusted, and a number of second pulling rollers 5 are installed between the two connecting plates 32, and the two ends of the second pulling rollers 5 are respectively rotatably installed on the two connecting plates 32, and the second pulling rollers 5 are respectively staggered between two adjacent first pulling rollers 4; a driving mechanism 6 for moving the two connecting plates 32 simultaneously toward or away from the first pulling rollers 4 is installed on the mounting side plates 31.

[0036] During the actual production and processing process, part of the coil can be wound and cached in the cache bracket 3 through the first pulling roller 4 and the second pulling roller 5. When the coil on the unwinding mechanism 1 is exhausted, the operator can install a new coil on the unwinding mechanism 1 and stick the new coil to the coil in the cache mechanism. This can avoid the operation of stopping the machine to replenish the coil, and can improve the production efficiency of the gluing equipment.

[0037] In addition, since the connecting plate 32 on which the second pulling roller 5 is installed can be driven by the driving mechanism 6 to move toward or away from the first pulling roller 4, the height of the second pulling roller 5 can be adjusted, making it convenient for the operator to adjust the cache bracket 3 to adjust the cache amount of the coil as needed.

[0038] Reference Figure 2 The driving mechanism 6 includes a first shaft rod 61, two first chains 62 and two driving parts. The two ends of the first shaft rod 61 are respectively rotatably mounted on the two mounting side plates 31, and the first shaft rod 61 passes through one end of the two mounting side plates 31 and is fixedly mounted with a driving sprocket 611. Two sets of transmission sprocket groups 64 are respectively rotatably mounted on the outer walls of the two mounting side plates 31. The two first chains 62 are respectively sleeved on the two driving sprockets 611 and the two sets of transmission sprocket groups 64.

[0039] A first adjusting sprocket 65 is fixedly installed at both ends of the first shaft 61, and the two first adjusting sprockets 65 are located on the inner sides of the two mounting side plates 31. Two second adjusting sprockets 66 are rotatably installed on the inner side walls of the two mounting side plates 31. The two second adjusting sprockets 66 are respectively located below the two first adjusting sprockets 65, and second chains 67 are respectively sleeved on the opposite first adjusting sprockets 65 and second adjusting sprockets 66. The two connecting plates 32 are fixedly connected to the two second chains 67 respectively.

[0040] The two driving members are respectively fixedly mounted on the outer side walls of the two mounting side plates 31 , and the driving ends of the two driving members are respectively fixedly connected to the two first chains 62 . The two driving members simultaneously drive the two chains to move in the same direction.

[0041] The driving member drives the first chain 62 to move in different directions. The movement of the first chain 62 can drive the first shaft 61 to rotate by driving the sprocket 611, and then drive the first adjusting sprocket 65 on the first shaft 61 to rotate, so that the first chain 62 installed on the first adjusting sprocket 65 and the second adjusting sprocket 66 moves. Since the two connecting plates 32 are fixedly installed on the connecting plate 32, the two connecting plates 32 on which the second traction roller is installed can be driven to rise or fall at the same time, thereby achieving the technical effect of adjusting the height of the second traction roller and adjusting the cache amount of the coil by the cache bracket 3.

[0042] Reference Figure 2 In this embodiment, the driving member is a telescopic cylinder 63, the cylinder bodies of the two telescopic cylinders 63 are respectively fixedly mounted on the outer walls of the two mounting side plates 31, and the cylinder shaft ends of the two telescopic cylinders 63 are respectively fixedly connected to the two first chains 62.

[0043] The telescopic cylinder 63 extends or retracts the cylinder shaft to drive the first chain 62 to move in different directions. The transmission sprocket set 64 can synchronously drive the first shaft 61 and the first adjustment sprocket 65 to rotate, and then the second chain 67 rotates to drive the two connecting plates 32 to move up and down.

[0044] It should be noted that, referring to Figure 2 In the embodiment of the present application, the transmission sprocket group 64 is composed of three transmission sprockets, two of which are arranged approximately in an L shape with the drive sprocket 611, and the third transmission sprocket is limited to the outside of the first chain 62, so that the first chain 62 as a whole is approximately arranged in an L shape.

[0045] In addition, in some other embodiments, a servo motor can be installed on the cache bracket 3, and the first chain 62 can be driven to move by driving any driving sprocket 611 to rotate through the servo motor, which is not limited or elaborated here.

[0046] Reference Figure 2 A second shaft rod 68 is installed between the two mounting side plates 31. The second shaft rod 68 is located directly below the first shaft rod 61, and both ends of the second shaft rod 68 are rotatably connected to the two mounting side plates 31 respectively. The two second adjustment sprockets 66 are fixedly mounted on the second shaft rod 68.

[0047] The two second adjusting sprockets 66 can be mounted via the second shaft 68 .

[0048] Reference Figure 2Two guide rods 311 are fixedly installed on the inner walls of the two mounting side plates 31, and sliders 321 are fixedly installed on the two connecting plates 32. Sliding holes that are compatible with the guide rods 311 are respectively opened on the sliders 321, and the sliders 321 are slidably set on the guide rods 311.

[0049] The guide rod 311 can limit the sliding trajectory of the two connecting plates 32, reduce the shaking and deviation of the two connecting plates 32 and the second traction roller between the two connecting plates 32 during the lifting process, and improve the stability of the lifting and lowering actions of the two connecting plates 32 and the second traction roller between the two connecting plates 32.

[0050] Reference Figure 2 A mounting top plate and a mounting bottom plate are fixedly mounted on the inner side wall of the mounting side plate 31, and the two ends of the guide rod 311 are fixedly connected to the mounting top plate and the mounting bottom plate respectively; a spring is fixedly mounted on the mounting bottom plate, and the spring is coaxially sleeved on the guide rod 311.

[0051] The spring can limit the lowest position of the connecting plate 32. At the same time, when the slider 321 on the connecting plate 32 is against the spring and the telescopic cylinder 63 drives the connecting plate 32 to move upward, the spring recovery can form an upward elastic force on the connecting plate 32, accelerating the reset of the connecting plate 32.

[0052] It should be noted that, referring to Figure 2 In this embodiment, the number of the slider 321 on the connecting plate 32, the guide rod 311 on the mounting side plate 31, and the spring on the guide rod 311 are all three. The number of the slider 321, the guide rod 311, and the spring can be increased or decreased according to actual needs, and no limitation or elaboration is made here.

[0053] Reference Figure 1 A sealing plate 33 is fixedly installed between the two mounting side plates 31, and a discharge port for the coil is formed at the bottom of the sealing plate 33; an inspection platform 7 is fixedly installed on the ground between the sealing plate 33 and the gluing mechanism 2, and the inspection platform 7 is erected above the discharge port, and a channel for the coil to flow is opened through the inspection platform 7.

[0054] The sealing plate 33 can protect the leather material. After the leather material is sent out through the discharge port at the bottom of the sealing plate 33, it can be transported to the gluing mechanism 2 through the channel under the maintenance platform 7 for gluing processing. When the gluing equipment needs to be repaired, the maintenance personnel can stand on the maintenance platform 7 to repair and maintain the gluing equipment, which can improve the convenience of maintenance and repair operations on the gluing equipment.

[0055] The implementation principle of the pre-put-on-buffer caching device of the gluing equipment is as follows: in the actual production process, through the first pulling roller 4 and the second pulling roller 5, part of the roll material can be wound and buffered in the buffering support 3; when the roll material on the unwinding mechanism 1 is exhausted, the operator can install new roll material on the unwinding mechanism 1, and stick and fix the new roll material with the roll material in the buffering mechanism, so that the operation of stopping and supplementing the roll material can be avoided, and the production efficiency of the gluing equipment can be improved.

[0056] The above are preferred embodiments of the present application, but do not limit the protection scope of the present application, therefore: all equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
