Description
Technical Field
[0001] The present application relates to the field of gluing equipment, and in particular to a post-winding buffer device for gluing equipment. Background Art
[0002] In order to improve the service life and quality of leather, it is usually necessary to perform a gluing process on the leather surface. Gluing is a process of evenly coating a sizing agent (including solvent sizing agent, latex, and aqueous sizing agent) onto the fabric surface through a gluing device.
[0003] In the prior art, common gluing equipment mainly includes a frame, on which a unwinding mechanism, a tension control mechanism, a winding mechanism, a gluing mechanism, a cooling and drying mechanism, etc. are installed. Among them, the unwinding mechanism evenly unwinds the raw material coil, and the coil passes through the tension control mechanism and then through the gluing mechanism. After the coil passing through the gluing mechanism is sent out, the cooling and drying mechanism cools the coil, so that the sizing agent on the coil surface dries, and the coil after the sizing agent dries is wound by the winding mechanism. In addition, common gluing equipment often needs to install a post-buffer mechanism between the cooling and drying mechanism and the winding mechanism to buffer the leather with the dried sizing agent on the surface. The common post-buffer mechanism consists of two groups of buffer rollers, and both ends of the two groups of buffer rollers are rotatably installed on the frame, and the coil winds around the buffer rollers after passing through the cooling and drying mechanism.
[0004] However, according to the need of different leathers for the thickness of the sizing agent, it is often necessary to adjust the speed of the leather passing through the cooling and drying mechanism according to the drying speed of the sizing agent on the coil surface. However, the relative positions of the existing buffer rollers are fixed, and the leather is prone to being too loose or too tight during the process of adjusting the coil conveying speed, so there is room for improvement. Utility Model Content
[0005] In order to achieve the technical effect of automatically adjusting the tightness of the leather on the post-buffer mechanism, the present application provides a post-winding buffer device for gluing equipment.
[0006] The post-winding buffer device for gluing equipment provided by the present application adopts the following technical solutions:
[0007] A post-winding buffer device for gluing equipment includes a frame, a plurality of fixed buffer rollers, and a plurality of floating buffer rollers. The plurality of fixed buffer rollers are arranged above the plurality of floating buffer rollers, and the plurality of fixed buffer rollers and the plurality of floating buffer rollers are arranged in a staggered manner;
[0008] The frame includes two opposite side plates. Both ends of the plurality of fixed buffer rollers are rotatably installed on the two side plates respectively. Two lifting plates are slidably installed on the two side plates respectively. Both ends of the plurality of floating buffer rollers are rotatably installed on the two lifting plates;
[0009] An outlet is formed between the two side plates, and the outlet is located on one side of the two side plates close to the winding mechanism. A floating positioning mechanism for positioning the height of the lifting plate is installed at the outlet between the two side plates.
[0010] By adopting the above technical solution, when the operator adjusts the conveying speed of the leather material, the floating positioning mechanism adjusts the adjustment positions of the two lifting plates to adjust the distance between the floating buffer roller and the fixed buffer roller, and automatically adjusts the tightness of the wound material between the floating buffer roller and the fixed buffer roller.
[0011] Preferably, a first shaft rod and a second shaft rod are installed between the two side plates. Both ends of the first shaft rod and the second shaft rod are respectively rotatably connected to the two side plates, and the first shaft rod is erected above the second shaft rod;
[0012] First sprockets are respectively fixedly installed at both ends of the first shaft rod, second sprockets are respectively fixedly installed at both ends of the second shaft rod, and the two first sprockets are respectively erected above the two second sprockets. Opposite first sprockets and second sprockets are sleeved with first chains, and the two lifting plates are respectively fixedly installed on the two first chains.
[0013] By adopting the above technical solution, through the arrangement of the first sprockets, second sprockets and first chains, when the operator speeds up the conveying speed of the wound material, multiple floating buffer rollers sink under the action of gravity, so that the wound material between the fixed buffer roller and the floating buffer roller is tightened again; when the operator slows down the conveying speed of the wound material, multiple floating buffer rollers rise due to the lifting of the wound material, so that the tension of the wound material remains constant. Since the two lifting plates are installed on the two chains, and the two chains are sleeved on the first sprockets and second sprockets, during the lifting and lowering process of the lifting plates and the floating buffer rollers, the first sprockets, second sprockets and first chains can be matched with each other to make the two lifting plates lift and lower simultaneously, so that the floating buffer rollers between the two lifting plates can be kept horizontal, and the stability of the lifting action of the floating buffer rollers can be improved.
[0014] Preferably, sliders are respectively fixedly installed on the outer sides of the two lifting plates, and first guide rods are respectively fixedly installed on the inner side walls of the two side plates. The sliders are respectively slidably installed on the first guide rods.
[0015] By adopting the above technical solution, the first guide rods and the sliders are used in combination, so that the two lifting plates can lift and lower linearly along the axial direction of the guide rods, and the situation of position deviation of the lifting plates during the lifting and lowering process can be reduced.
[0016] Preferably, the floating positioning mechanism includes a transition roller, an adjusting roller, two third sprockets, two second chains and two groups of counterweights;
[0017] The transition roller is located at the discharge port. Both ends of the transition roller are rotatably connected to the two side plates. The adjusting roller is located on one side of the transition roller away from the floating buffer roller and the fixed buffer roller. Mounting seats are slidably installed on the two side plates respectively. Both ends of the adjusting roller are rotatably installed on the two mounting seats respectively, and the adjusting roller is arranged lower than the transition roller.
[0018] Two of the third sprockets are respectively rotatably installed on the two side plates. One ends of the two second chains are respectively fixedly connected to the two mounting seats. The other ends of the two second chains away from the mounting seats are respectively fixedly connected to the two groups of counterweight blocks.
[0019] By adopting the above technical solutions, during the lifting and lowering process of the floating buffer roller, the adjusting roller rises or falls under the action of the coiled material and the counterweight blocks, and finally the balance of the adjusting roller is formed. The two groups of counterweight blocks can ensure the balanced force on the two lifting plates and the stability of the two lifting plates.
[0020] Preferably, two second guide rods are fixedly installed on the two side plates. The two mounting seats are slidably installed on the two second guide rods.
[0021] By adopting the above technical solutions, the two sliding seats are installed on the two second guide rods, so that the adjusting roller can only move up and down along the second guide rods, which can limit the up and down movement track of the adjusting roller and improve the stability of the up and down movement of the adjusting roller.
[0022] Preferably, mounting columns are fixedly installed at the ends of the two third sprockets away from the mounting seats. Mounting sockets adapted to the mounting columns are respectively formed on the counterweight blocks. Trays for stacking the two groups of counterweight blocks are respectively fixedly installed on the two mounting columns.
[0023] By adopting the above technical solutions, through the arrangement of the mounting columns and the trays, the operator can adjust the number of counterweight blocks on the trays and the counterweight according to the actual use requirements.
[0024] In summary, the post-winding buffer device for a glue coating device of the present application has at least one of the following beneficial technical effects:
[0025] 1. Through the arrangement of the first sprocket, the second sprocket and the first chain, when the operator speeds up the conveying speed of the coiled material, multiple floating buffer rollers sink under the action of gravity, so that the coiled material wound between the fixed buffer roller and the floating buffer roller is re-tightened; when the operator slows down the conveying speed of the coiled material, multiple floating buffer rollers rise due to the lifting of the coiled material, so that the tension of the coiled material remains constant.
[0026] 2. Since the two lifting plates are installed on two chains, and the two chains are sleeved on the first sprocket and the second sprocket, during the lifting process of the lifting plates and the floating buffer roller, the first sprocket, the second sprocket and the first chain cooperate with each other to enable the two lifting plates to lift simultaneously, so that the floating buffer roller between the two lifting plates can be kept horizontal, improving the stability of the lifting action of the floating buffer roller;
[0027] 3. During the lifting process of the floating buffer roller, the adjusting roller rises or falls under the action of the coiled material and the counterweight block, and finally the balance of the adjusting roller is formed. The two groups of counterweight blocks can ensure the force balance of the two lifting plates and the stability of the two lifting plates. Description of the Drawings

Detailed Description of the Embodiment
[0032] The following is a further detailed description of the present application in conjunction with the attached Figures 1-3 drawings.
[0033] Embodiment
[0034] The embodiment of the present application discloses a post-winding buffer device for a gluing equipment. Refer to Figure 1 and Figure 2, including a frame 1, a plurality of fixed buffer rollers 2 and a plurality of floating buffer rollers 3. The plurality of fixed buffer rollers 2 are installed above the plurality of floating buffer rollers 3, and the plurality of fixed buffer rollers 2 and the plurality of floating buffer rollers 3 are arranged in a staggered manner; the frame 1 includes two opposite side plates 11. The two ends of the plurality of fixed buffer rollers 2 are respectively rotatably installed on the two side plates 11. Two lifting plates 12 are respectively slidably installed on the two side plates 11. The two ends of the plurality of floating buffer rollers 3 are respectively rotatably installed on the two lifting plates 12; a discharge port is formed between the two side plates 11, and the discharge port is located on one side of the two side plates 11 close to the winding mechanism. A floating positioning mechanism 4 for positioning the height of the lifting plate 12 is installed at the discharge port between the two side plates 11.
[0035] When the operator adjusts the conveying speed of the leather material, the floating positioning mechanism 4 adjusts the positions of the two lifting plates 12 to adjust the distance between the floating buffer rollers 3 and the fixed buffer rollers 2, and automatically adjusts the tightness of the coil material wound between the floating buffer rollers 3 and the fixed buffer rollers 2.
[0036] Referring to the figure, a first shaft rod 14 and a second shaft rod 15 are installed between the two side plates 11. The two ends of the first shaft rod 14 and the second shaft rod 15 are respectively rotatably connected to the two side plates 11, and the first shaft rod 14 is installed above the second shaft rod 15; first sprockets 16 are respectively fixedly installed at the two ends of the first shaft rod 14, and second sprockets 17 are respectively fixedly installed at the two ends of the second shaft rod 15, and the two first sprockets 16 are respectively installed above the two second sprockets 17. First chains 18 are sleeved on the opposite first sprockets 16 and second sprockets 17, and the two lifting plates 12 are respectively fixedly installed on the two first chains 18.
[0037] Through the arrangement of the first sprockets 16, the second sprockets 17 and the first chains 18, when the operator speeds up the conveying speed of the coil material, the plurality of floating buffer rollers 3 sink under the action of gravity, so that the coil material wound between the fixed buffer rollers 2 and the floating buffer rollers 3 is tightened again; when the operator slows down the conveying speed of the coil material, the plurality of floating buffer rollers 3 rise due to the lifting of the coil material, so that the tension of the coil material remains constant. Since the two lifting plates 12 are installed on the two chains, and the two chains are sleeved on the first sprockets 16 and the second sprockets 17, during the lifting and lowering process of the lifting plates 12 and the floating buffer rollers 3, the first sprockets 16, the second sprockets 17 and the first chains 18 can cooperate with each other to make the two lifting plates 12 lift and lower simultaneously, and can make the floating buffer rollers 3 between the two lifting plates 12 keep horizontal, improving the stability of the lifting action of the floating buffer rollers 3.
[0038] Referring to Figure 2 , slider 121 is fixedly installed on the outer sides of the two lifting plates 12, and first guide rods 111 are fixedly installed on the inner side walls of the two side plates 11. The sliders 121 are respectively slidably installed on the first guide rods 111.
[0039] The first guide rod 111 and the slider 121 are used in combination with each other, enabling the two lifting plates 12 to move up and down linearly along the axial direction of the guide rod, and reducing the occurrence of position deviation of the lifting plates 12 during the lifting process.
[0040] It should be noted that in the embodiment of the present application, the number of sliders 121 on the lifting plate 12 and the number of the first guide rods 111 on the side plates 11 are both 2. In some other embodiments, the number of the sliders 121 and the first guide rods 111 can be adjusted according to actual usage needs, and no limitation is made here.
[0041] Refer to Figure 2 , the floating positioning mechanism 4 includes a transition roller 41, an adjusting roller 42, two third sprockets 43, two second chains 45 and two groups of counterweights 44; the transition roller 41 is located at the discharge port, and both ends of the transition roller 41 are rotatably connected to the two side plates 11. The adjusting roller 42 is located on the side of the transition roller 41 away from the floating buffer roller 3 and the fixed buffer roller 2. Installation seats are respectively slidably installed on the two side plates 11, and both ends of the adjusting roller 42 are respectively rotatably installed on the two installation seats, and the adjusting roller 42 is arranged lower than the transition roller 41; the two third sprockets 43 are respectively rotatably installed on the two side plates 11, one ends of the two second chains 45 are respectively fixedly connected to the two installation seats, and the ends of the two second chains 45 away from the installation seats are respectively fixedly connected to the two groups of counterweights 44.
[0042] During the lifting process of the floating buffer roller 3, the adjusting roller 42 rises or falls under the action of the coiled material and the counterweights 44, and finally the balance of the adjusting roller 42 is formed. The two groups of counterweights 44 can ensure the force balance of the two lifting plates 12 and the stability of the two lifting plates 12.
[0043] Refer to Figure 2 , two second guide rods 112 are fixedly installed on the two side plates 11, and the two installation seats are slidably installed on the two second guide rods 112.
[0044] Two sliding seats 46 are installed on the two second guide rods 112, enabling the adjusting roller 42 to only move up and down along the second guide rods 112, which can limit the up and down movement trajectory of the adjusting roller 42 and improve the stability of the up and down movement of the adjusting roller 42.
[0045] Refer to Figure 2 And Figure 3 , mounting columns 47 are fixedly installed at the ends of the two third sprockets 43 away from the installation seats. Mounting sockets 441 adapted to the mounting columns 47 are respectively formed on the counterweights 44, and trays 48 for stacking the two groups of counterweights 44 are respectively fixedly installed on the two mounting columns 47.
[0046] Through the arrangement of the mounting posts 47 and the tray 48, the operator can adjust the number of counterweight blocks 44 on the tray 48 and the counterweight according to the actual usage needs.
[0047] The implementation principle of the post-winding buffer device for the glue application equipment in the embodiment of the present application is as follows: Through the arrangement of the first sprocket 16, the second sprocket 17 and the first chain 18, when the operator speeds up the conveying speed of the rolled material, multiple floating buffer rollers 3 sink under the action of gravity, so that the rolled material wound between the fixed buffer roller 2 and the floating buffer roller 3 is re-tightened; when the operator slows down the conveying speed of the rolled material, multiple floating buffer rollers 3 rise due to the lifting of the rolled material, so that the tension of the rolled material remains constant; since the two lifting plates 12 are installed on the two chains, and the two chains are sleeved on the first sprocket 16 and the second sprocket 17, during the lifting and lowering process of the lifting plates 12 and the floating buffer rollers 3, the first sprocket 16, the second sprocket 17 and the first chain 18 can be matched with each other to make the two lifting plates 12 lift and lower simultaneously, so that the floating buffer rollers 3 between the two lifting plates 12 can be kept horizontal, improving the stability of the lifting and lowering action of the floating buffer rollers 3; during the lifting and lowering process of the floating buffer rollers 3, the adjusting roller 42 rises or falls under the action of the rolled material and the counterweight block 44, and finally the balance of the adjusting roller 42 is formed. The two groups of counterweight blocks 44 can ensure the force balance of the two lifting plates 12 and the stability of the two lifting plates 12.
[0048] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape and principle of the present application shall be covered within the protection scope of the present application.
