Description

Technical Field

[0001] The invention relates to sponge production equipment, in particular to a sponge foaming production device with adjustable width. Background Art

[0002] At present, the continuous foaming production line used adjusts the height and inclination of multiple drop plates to reduce the resistance of the foam to overcome the climbing of the baffles on both sides during the foaming process, thereby slowing down or eliminating the arched part of the top of the foam. For the production of sponges with different densities and heights, the requirements for the height and inclination of the drop plates are different. Therefore, the vertical height and inclination of each drop plate on the production line can be adjusted by a lifting mechanism to meet production needs. The rear end of the drop plate is connected to a conveying mechanism, which can adopt a bottom chain plate. The raw material is formed into sponge after foaming on the drop plate and then conveyed on the bottom chain plate. Usually, side chain plates are arranged on both sides of the drop plate, and the conveying speed of the side chain plates is synchronized with that of the bottom chain plate. Similarly, to produce sponges of different widths, it is necessary to adjust the distance between the chain plates on both sides, and the width of the drop plate should also be adjusted. At present, the width of the drop plate of some sponge equipment is still adjusted manually, and some are adjusted by screw drive. However, the opening and closing of the chain plate mechanisms on both sides and the drop plate are independently operated, not synchronized, and the gap between the chain plate mechanisms on both sides and the drop plate is controlled manually. At the same time, the gap between multiple drop plates and the chain plates on both sides is often inconsistent. Sometimes, the gap is too large or too small, and there will be problems such as the gap is too large in some places and too small in some places. If it is too large, material will leak, and if it is too small, the plastic edge film on both sides of the sponge cannot pass, and even the side chain plate may be scratched.

[0003] Chinese patent application number: 201920817551.5 discloses a sponge foaming line drop plate, including a frame, a first beam and a second beam arranged on the frame, and a plurality of drop plates arranged above the first beam and the second beam, the adjacent drop plates are rotatably connected, the first beam and the second beam are provided with a plurality of first lifting mechanisms, each drop plate hinge is connected to a first lifting mechanism, the second beam is horizontally fixedly arranged on the frame, the first beam is hinged to the second beam, and the frame is provided with a second lifting mechanism. The width of the drop plate of the device is also adjusted by screw drive. Summary of the invention

[0007] Further:

[0008] The lifting mechanism includes two first bearing seats arranged on the frame, a first sprocket rotatably arranged on the first bearing seat, a first screw rod threadedly connected to the first sprocket and passing through the first bearing seat, and a first driving motor arranged on the frame. The two first sprockets are connected to the first driving motor through a first chain. The first driving motor drives the first screw rod to perform up and down lifting movements. The tops of the two first screw rods are rotatably connected to the first drop plate respectively.

[0009] The second drop plates are respectively provided on both sides of the first drop plate, the two side chain plate mechanisms are respectively movably provided on the frame, the driving mechanism includes a plurality of screws rotatably provided on the frame, a second sprocket provided on each screw, a second chain connecting the second sprocket, and a second driving motor for driving the second sprocket to rotate, a second nut seat is provided on the side chain plate mechanism, both ends of each screw are respectively threadedly connected to the second nut seat, the screw is a forward and reverse screw, and the second driving motor drives the two side chain plate mechanisms to move in opposite or opposite directions.

The projection of the operating table along the ground direction has an overlapping part with the projection of the observation walkway along the ground direction.

[0017] By adopting the above technical solution, the beneficial effects of the present invention are:

[0018] The present invention can adjust the position of at least one side chain plate through a driving mechanism, thereby adjusting the distance between the two side chain plates. When the side chain plate mechanism moves, the side chain plate mechanism drives the second hydraulic cylinder to extend and retract. The cylinder barrels of the first hydraulic cylinder and the second hydraulic cylinder have the same cross-sectional area and the same cylinder barrel length. The liquid in the cylinder barrel of the first hydraulic cylinder and the liquid in the cylinder barrel of the second hydraulic cylinder are connected through a conduit. The second hydraulic cylinder will drive the first hydraulic cylinder to do the opposite action. When the second hydraulic cylinder stretches, the first hydraulic cylinder shortens. When the second hydraulic cylinder is compressed, the first hydraulic cylinder extends. The cylinder barrels of the first hydraulic cylinder and the second hydraulic cylinder have the same cross-sectional area, so the displacements of the first hydraulic cylinder and the second hydraulic cylinder are the same, that is, the first hydraulic cylinder The stroke of the cylinder and the second hydraulic cylinder is the same, and the first hydraulic cylinder pushes the second drop plate to move longitudinally, so that the side chain plate mechanism and the second drop plate move synchronously in the same direction, the gap between the side chain plate and the drop plate is kept consistent in real time, and the distance between the side chain plate and each second drop plate is kept consistent, so as to prevent the side chain plate mechanism and the second drop plate from having different distances after movement, or the distance between the side chain plate and each second drop plate from having different distances after movement. If the distance is too large, it may cause material leakage, and the machine may be shut down in serious cases, causing losses. If the distance is too small, the side film may be scratched, and the machine may be shut down. In serious cases, the drop plate may scratch the side chain plate, causing equipment damage. The present invention controls the opening and closing of the side chain plate, adjusts the opening and closing of the drop plate, and utilizes Hydraulic cylinders with the same cylinder cross-sectional area have the same displacement principle under the push of the same volume of liquid. The liquid in the cylinder barrels of the two hydraulic cylinders is sealed and communicated, which ensures the synchronous displacement of the side chain plate and the drop plate, thereby ensuring that the gap between the chain plates on both sides and the drop plate is the same each time the side chain plate is opened and closed, and the gap between the chain plates on both sides and each drop plate is also the same. This is not only simple to operate, but also solves the problem of unnecessary troubles and losses caused by the gap between the side chain plate and the drop plate being too large or too small, and also solves the problem of unnecessary troubles and losses caused by inconsistent gaps between each drop plate and the side chain plate. The present invention can produce sponges of different widths with one device, thereby reducing the production cost, and the adjustment is simple and fast, thereby realizing automatic adjustment production. Further In the first step, the angle and height of the first drop plate and the second drop plate can be adjusted by the lifting mechanism, and the operation is simple and practical; further, two side chain plate mechanisms can be used to move simultaneously, and movable second drop plates are provided on both sides of the first drop plate. This symmetrical structure has a large adjustment range and the force on the frame is relatively balanced, so that the equipment runs smoothly and generates less vibration during the operation of the equipment; further, only one side of the side chain plate mechanism can be used to move, and only one side of the first drop plate is provided with a movable second drop plate. This structure is simple and can save the manufacturing cost of the production device; further, the setting of the guide rod and the guide block allows the second drop plate to move relative to the first drop plate along the guide rod, and the movement is stable;Furthermore, when the sponge is foaming, it is necessary to adjust the raw materials of the feeding device according to the real-time situation of the sponge foaming, so that the produced sponge is of high quality. If a camera is set on the rack for observation, the observation on the electronic screen is not as careful and accurate as the observation with the naked eye, and many details are difficult to present on the electronic screen. Therefore, it is necessary to observe the state of the raw materials when they are transported by the drop plate mechanism with the naked eye. The observation walkway of the present invention can move with the movement of the side chain plate mechanism, which is convenient for the staff to observe the real-time state of the sponge foaming with the naked eye on the observation walkway, and no matter how the observation walkway moves, the projection of the operation walkway along the ground direction and the projection of the observation walkway along the ground direction have an overlapping part, so that the operation walkway and the observation walkway are connected, which is convenient for the staff to walk back and forth between the operation walkway and the observation walkway. ; BRIEF DESCRIPTION OF THE DRAWINGS

[0048] The working method of the first embodiment is:

[0049] According to the width and length of the sponge to be produced, the height and inclination of the first drop plate 31 and the second drop plate 33 are adjusted by the lifting mechanism 32, and the width between the two side chain plate mechanisms 4 is adjusted by the driving mechanism 5. When the two side chain plate mechanisms 4 move, the column 41 pulls the plurality of second hydraulic cylinders 341 to move, and the plurality of second hydraulic cylinders 341 respectively drive the corresponding first hydraulic cylinders 342 to move, and the first hydraulic cylinder 342 pushes the second drop plate 33 to move, so that the side chain plate mechanism 4 and the plurality of second drop plates 33 move synchronously, so that the gap between the side chain plate mechanism 4 and the plurality of second drop plates 33 is maintained after each adjustment. The size of the kraft paper is about 3-8mm. The specific size depends on the actual situation. After adjustment, select the kraft paper of appropriate width. The kraft paper extends from the first drop plate 31 and the second drop plate 33 to the second chain plate 24. Start the production device. The feeding device 7 adds the raw material to the kraft paper on the drop plate mechanism 3. The bottom chain plate mechanism 2 moves, pulling the kraft paper to move with the second chain plate 24.
