Description

Technical Field

[0001] The present application relates to the technical field of compounding machines, and in particular to a roll changing mechanism of a hot melt adhesive compounding device. Background Art

[0002] The degree of automation in the composite production of traditional non-woven fabrics is low. With the development of technology, there are now many composite devices that can achieve semi-automatic production, which greatly improves production efficiency. However, workers are required to operate the composite device when it is running, especially for roll changing. Roll changing means removing the reel that has been rolled up with finished fabric. It is necessary to stop the composite device, manually remove the reel, and then place the empty reel on the composite device and rewind it again.

[0003] Some cloth rolls are large in size and heavy in weight. This winding method requires a lot of manpower, which has high labor costs. In addition, manual winding and placing empty rolls take a long time, which cannot achieve rapid continuous production, resulting in the inability to further improve production efficiency.

[0004] Therefore, there is a need for a roll-changing mechanism that can replace manual reeling and unreeling, reduce the labor intensity of workers, reduce costs, and further improve the production efficiency of the composite device. Utility Model Content

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0038] The following is combined with Figures 1 to 4 This application is described in further detail.

[0039] The embodiment of the present application discloses a roll changing mechanism for a hot melt adhesive compounding device.

[0040] Reference Figures 1 to 4 A roll-changing mechanism of a hot-melt adhesive compounding device comprises: a pressing roller 1, a turning component, a roll placement rack, and a winding component.

[0041] The pressing roller 1 has two ends rotatably arranged on a frame 2, and a turning assembly is coaxially (coaxially, but not fixed) arranged at the two ends of the pressing roller 1.

[0042] The turning assembly includes a turning cylinder 3, a turning gear 4, a transmission shaft 5, and a power part 6.

[0043] There are two flipping gears 4, and the two flipping gears 4 are coaxially rotatably arranged with the two ends of the pressing roller 1. A flipping cylinder 3 is fixedly arranged outside the two flipping gears 4, and the flipping angles of the two flipping cylinders 3 are the same. A flipping block is fixed at the end of the telescopic rod of the flipping cylinder 3, and an opening 7 is opened on the flipping block. A limit rod 8 is arranged at the opening 7, and is driven to move by a limit cylinder 9 fixed on the flipping block. Through the setting of the limit rod 8, when the flipping cylinder 3 drives the reel 23 to flip, the limit cylinder 9 can push the limit rod 8 to extend to prevent the reel 23 from leaving the opening 7, so as to ensure that the reel 23 can flip with the flipping cylinder 3.

[0044] The two ends of the transmission shaft 5 are rotatably arranged on the frame 2, located below the pressing roller 1. The two ends of the transmission shaft 5 are fixedly provided with driving gears 10, and the two driving gears 10 are respectively meshed with the two flipping gears 4 through the intermediate gear 11. The power member 6 is fixed on the frame 2 at one end of the pressing roller 1. The power member 6 is a motor group, which directly drives the transmission shaft 5 to rotate. The two flipping cylinders 3 are driven by gears to achieve synchronous flipping under the drive of the power member 6.

[0045] The reel placement rack is located at one side of the pressure roller 1 and is used to place an empty reel 23 .

[0046] The reel placement rack includes a guide rod 12, both ends of which are arranged on the frame 2, one end of the guide rod 12 is fixed with a fixed support 13, a sliding support 14 is slidably arranged on the guide rod 12, one end of the reel 23 can be placed on the sliding support 14, and the reel 23 can be quickly pushed and pushed in by sliding the sliding support 14, so as to realize the rapid placement of the empty reel 23. Two baffles 15 are fixed on the frame 2, and the two baffles 15 are located on both sides of the guide rod 12. The baffles 15 can prevent the reel 23 from falling on the sliding support 14 and the fixed support 13, causing collision damage.

[0047] The winding assembly is located on the other side of the pressure roller 1, and includes a movable seat 16. The movable seat 16 is slidably matched with the frame 2 through a slide rail slider, and is set on the frame 2 along the radial movement of the pressure roller 1. It is driven to slide by a cylinder B17 fixed on the frame 2. Through the setting of the cylinder B17, the movable seat 16 can be driven to move, so that the reel 23 can be against or away from the pressure roller 1. The top of the movable seat 16 is inclined, and the height gradually decreases in the direction away from the pressure roller 1. The movable seat 16 is fixed with a cylinder A18, and a winding groove 19 is fixed at the end of the telescopic rod of the cylinder A18. The winding groove 19 is used to place the reel 23.

[0048] A plurality of guide rollers 20 are arranged on the frame 2, and the plurality of guide rollers 20 are used to guide and support the composite finished product.

[0049] A guard plate 21 fixed on the frame 2 is arranged on the periphery of the flip gear 4, and the guard plate 21 has a protective function to prevent accidental injuries to personnel when the gear rotates.

[0050] Protective covers 22 are fixed on the frames 2 at both ends of the pressing roller 1 to play an isolation and protection role.

[0051] When the composite device is running, the reel 23 can be placed on the reel placement rack in advance. After the reel 23 has rolled up the fabric, the cylinder A18 can drive the reeling slot 19 to descend. Due to the inclined setting of the top of the moving seat 16, the reel 23 automatically rolls down to complete the lower roll. A device for receiving the roll can be set at the lower roll, or when the weight is light, it can be directly carried manually. Through the setting of the flip assembly, it rotates under the drive of the power part 6. First, the flip cylinder 3 rotates, and the flip block is located below the reel 23. At this time, the telescopic rod of the flip cylinder 3 extends, driving the flip block to move to a suitable position, that is, below the reel 23. The flip cylinder 3 starts to flip, and the reel 23 falls into the opening 7. The limit cylinder 9 pushes the limit rod 8 to extend, and the reel 23 is stuck in the opening 7. The flip cylinder 3 continues to flip. At the same time, the telescopic rod of the flip cylinder 3 contracts, driving the reel 23 to resist the pressure roller 1 and continue to flip until it flips 180°, driving the reel 23 to rotate along the surface of the pressure roller 1 to the winding groove 19, thereby realizing the replacement of the reel 23.
