Description

Technical Field

[0001] The utility model belongs to the technical field of coating machines, and particularly relates to a low-tension linkage front storage rack. Background Art

[0002] Coating machines are mainly used in the surface coating process production of films, papers, etc. This machine coats a roll of base material with a specific functional glue, coating, ink, etc., and after drying, it is cut into pieces or wound up. Among them, a storage rack for the passing of the coil material is arranged before the coating station, so that the coil material can be fully unfolded before coating and the feeding continuity during roll change can be maintained.

[0003] A non-woven fabric rewinding system and rewinding method suitable for continuous production disclosed in Patent CN118047249A belong to the technical field of non-woven fabric rewinding. The non-woven fabric rewinding system includes a controller and a unwind machine, a storage machine, a hot roll shaping machine, a layout cooling system and a rewinder connected in sequence. The storage machine includes a storage rack, a storage fixed roller group, a storage lifting system and several roller speed regulation systems. The storage fixed roller group is installed on the storage rack and connected to the storage lifting system. The storage lifting system is installed on the storage rack, and each roller speed regulation system is installed on the storage lifting system. By controlling the lifting power device to rise or fall through the controller, the storage machine can switch between the storage state and the feeding state, and the controller can control the roller speed regulation system to adjust the speed to meet the linear speed requirements of non-woven fabric conveying at each position. Each roller speed regulation system is slidably installed on the storage lifting rod, avoiding the direct and rapid change of the non-woven fabric tension caused by the movement of the storage lifting rod.

[0004] In the above solution, although the controller controls the lifting power device to rise or fall, so that the storage machine can switch between the storage state and the feeding state, and the controller can control the roller speed regulation system to adjust the speed to meet the linear speed requirements of non-woven fabric conveying at each position, the control of the lifting power device cannot dynamically maintain the tensile tension of the coil material. When the height of the upper roller group changes, it must be accompanied by a change in tension, which directly affects the subsequent processing quality of the coil material. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the above problems and provide a low-tension linkage front storage rack that can solve the above technical problems.

Detailed Implementation Manner

[0022] The following are specific embodiments of the utility model and in conjunction with the drawings, the technical solutions of the present utility model are further described, but the present utility model is not limited to these embodiments.

[0023] As Figure 1 - Figure 2 shown, a low-tension linkage front storage rack includes a storage frame 1. A fixed crossbeam roller frame 11 is provided at the lower end of the storage frame 1. A moving crossbeam roller frame 12 that moves up and down is provided in the storage frame 1. A serpentine storage channel is provided between the fixed crossbeam roller frame 11 and the moving crossbeam roller frame 12. A load-bearing sprocket 2 is provided at the top of the storage frame 1. The moving crossbeam roller frame 12 is connected to a counterweight block 22 through a balance chain 21 that is hung on the load-bearing sprocket 2.

[0024] That is, the moving crossbeam roller frame 12 that moves up and down in the storage frame 1 is gravity-balanced by the counterweight block 22 connected by the balance chain 21, and the rotation of the load-bearing sprocket 2 on which the balance chain 21 is hung promotes the up and down movement of the moving crossbeam roller frame 12. In this way, when driving the moving crossbeam roller frame 12, there is no need to overly counteract the gravity of the crossbeam roller frame itself, and it can be controlled with a smaller and more stable driving force, thereby keeping the tension received by the coil stock in a balanced state.

[0025] In this embodiment, an adjusting cylinder 31 that expands and contracts up and down is provided on the storage frame 1. The output end of the adjusting cylinder 31 is in transmission connection with the load-bearing sprocket 2 through a drive chain 32.

[0026] The rotation of the load-bearing sprocket 2 determines the height of the driving moving beam roller frame 12, and the extension and contraction of the regulating cylinder 31 determines the rotation of the load-bearing sprocket 2, dividing the motion mechanism of the beam usually directly controlled by the cylinder into two indirectly related sets, making the motion control more precise.

[0027] In this embodiment, an adjusting sprocket 33 is provided at the output end of the adjusting cylinder 31, one end of the transmission chain 32 is fixed to the upper side of the material storage frame 1, and the other end of the transmission chain 32 passes through the lower edge of the adjusting sprocket 33 and the upper edge of the load-bearing sprocket 2 and is connected to the adjusting counterweight 34.

[0028] One end of the transmission chain 32 is fixed to the material storage frame 1, and the other end is pulled by gravity by the adjusting counterweight 34, so that the transmission chain 32 is tightly attached to the lower edge of the adjusting sprocket 33 and the upper edge of the load-bearing sprocket 2, that is, the pushing and pulling activities of the adjusting cylinder 31 are counteracting the adjusting counterweight 34.

[0029] When the regulating cylinder 31 contracts or extends, the transmission chain 32 is pulled downward and upward, and the transmission chain 32 cooperates with the toothed chain of the bearing sprocket 2 to drive it to rotate, thereby dragging the moving beam roller frame 12 to move up and down.

[0030] In this embodiment, the load-bearing sprocket 2 includes two coaxial sprockets, one of which is mounted against the transmission chain 32 , and the other is mounted against the balance chain 21 .

[0031] Since the material storage frame 1 includes two sets of movable mechanisms, the load-bearing sprocket 2 has two coaxially arranged sprockets to connect the driving forces of the two sets of movable structures.

[0032] Preferably, two load-bearing sprockets 2 are provided on the material storage frame 1 corresponding to the two sides of the movable beam roller frame 12 , and the two load-bearing sprockets 2 are connected by a transmission chain 32 .

[0033] In order to be able to lift and lower the moving beam roller frame 12 in a balanced manner, load-bearing sprockets 2 are respectively installed on the upper positions on both sides of the material storage frame 1 corresponding to the moving beam roller frame 12. Each load-bearing sprocket 2 is also responsible for supporting the movable structure of the moving beam roller frame 12 and the counterweight block 22 on both sides, and the transmission chain 32 is simultaneously laterally hung on the two load-bearing sprockets 2. The height change of the output end of the adjusting cylinder 31 is used to drag the transmission chain 32 to make the two load-bearing sprockets 2 rotate synchronously.

[0034] Preferably, a tension display meter 35 is provided on the material storage frame 1, and the tension display meter 35 is connected to the load-bearing sprocket 2 through a plurality of reduction transmission wheels.

[0035] A plurality of runner belt assemblies are also attached to the load-bearing sprocket wheel 2. The runner belt assemblies are connected in a step-by-step decelerating manner and finally transmission-connected to the tension display meter 35. The gradually reduced rotation angle can be visually displayed on the tension display meter 35, and the displayed value of the tension display meter 35 is the magnitude of the tension applied to the coiled material at this time.

[0036] In this embodiment, a tensioning sprocket wheel 36 is provided on the fixed crossbeam roller frame 11. Both ends of the balance chain 21 are connected to the counterweight 22. The chain body of the balance chain 21 successively passes over the upper edge of the load-bearing sprocket wheel 2, the movable crossbeam roller frame 12 fixedly connected thereto, and the lower edge of the tensioning sprocket wheel 36.

[0037] Both ends of the balance chain 21 are connected head-to-tail with the counterweight 22 to form a loop, sleeved on the upper and lower load-bearing sprocket wheels 2 and the tensioning sprocket wheel 36 and reaching a tension degree for chain drive. Then, the movable crossbeam roller frame 12 is fixed on the straight chain on the other side of the counterweight 22. When the balance chain 21 rotates on the load-bearing sprocket wheel 2 and the tensioning sprocket wheel 36, the counterweight 22 and the movable crossbeam roller frame 12 can achieve a trend of moving up and down.

[0038] In this embodiment, guide wheels 13 are provided on both sides of the movable crossbeam roller frame 12, and guide rails 14 corresponding to the guide wheels 13 are provided on the storage frame 1.

[0039] To prevent the movable crossbeam roller frame 12 from shaking during the lifting and lowering process and affecting the tension change, guide wheels 13 are installed at both ends of the movable crossbeam roller frame 12, and guide rails 14 are provided on the vertical beams on both sides of the storage frame 1, so that the movable crossbeam roller frame 12 moves vertically up and down along the guide rails 14 to avoid horizontal shaking and pulling on the coiled material.

[0040] In this embodiment, a number of storage rollers 15 are horizontally provided on the movable crossbeam roller frame 12 and the fixed crossbeam roller frame 11. The storage rollers 15 on the movable crossbeam roller frame 12 and the storage rollers 15 on the fixed crossbeam roller frame 11 are distributed vertically offset.

[0041] In order to achieve a serpentine detour distribution of the storage channel to ensure the smooth passage and tension of the coiled material, the upper and lower storage rollers 15 are vertically offset, and to avoid collision between the upper and lower storage rollers 15 when the movable crossbeam roller frame 12 descends to the bottom.

[0042] In this embodiment, a locking roller group 4 is provided on the storage frame 1, and the locking roller group 4 is respectively provided at the front and rear ends of the storage channel.

[0043] The locking roller group 4 includes a fixed roller and a clamping roller. The fixed roller and the clamping roller can rotate in contact with each other. The coil enters and exits between the fixed roller and the clamping roller. A locking cylinder is provided on the clamping roller. The piston rod of the locking cylinder faces the rotating shaft of the clamping roller. When it is necessary to lock the movement of the coil, the piston rod is pushed out to press against the rotating shaft, and the clamping roller increases the pressure against the fixed roller, thereby clamping the coil while preventing rotation.

[0044] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
