the strip shifting reversing unit 4 is arranged above the carrier short strip conveying belt 5 so as to periodically shift the carrier short strips in transportation to the roller cutting forming equipment 7 for cutting and granulating to obtain a carrier finished product;
the collecting hopper 8 is arranged below a discharge port of the roller cutting and shaping device 7, and a screen 9 is erected in the middle of the collecting hopper 8 and used for screening and collecting carrier finished products with different sizes.

Each cut fixed-length carrier strip moves forwards through a conveying device, and the carrier strips are successively and continuously conveyed to a roller cutting molding device 7 for cutting and granulation according to a certain time interval by a strip shifting reversing unit 4 along the vertical direction of the carrier strip movement to obtain a carrier finished product. Meanwhile, the collection hopper 8 is matched with the screen 9, so that the primary screening of the granulated carrier finished product can be realized, and the subsequent processing steps can be conveniently collected and used. Therefore, the problems of discontinuous forming production process, low production efficiency and irregular product appearance of the catalyst carrier in the prior art are solved, the continuous production of the catalyst carrier is realized, and the automation level is high; meanwhile, the structure is compact, the occupied area is small, and the production and processing operation space is saved.
In order to realize the intellectualization of the catalyst carrier forming device during the use process, so that the period of a plurality of processing operation processes can be adjusted to meet the requirement of production beat, the device preferably also comprises a control unit 6 for controlling the continuous operation of the device.
In the present embodiment, in order to simplify and optimize the internal structure of the roller cutting and forming device 7, when each cut carrier strip with a fixed length falls from the carrier strip conveyer belt 5 into the roller cutting and forming device 7 for cutting and granulating, the cut carrier strip with a fixed length is smoother, the success rate of cutting and granulating is ensured, and the production and processing efficiency is improved, preferably, as shown in fig. 2, the roller cutting and forming device 7 includes a material pouring roller 71, a rotating roller 72 and a cutting knife 73; the material pouring roller 71 is positioned above the cutting roller, and a plurality of material pouring sheets are formed on the material pouring roller 71 at uniform intervals along the circumferential direction and used for conveying the carrier short strips falling from the carrier short strip conveying belt 5 to a gap between the lower rotating roller 72 and the lower cutting knife 73; the cutter 73 is a hob and is matched with the rotary roller 72 to cut and granulate the carrier short strips in the gap, and the granulated carrier finished product falls into the collecting hopper 8 from the gap between the rotary roller 72 and the cutter 73.
Thus, when the material pouring roller 71 rotates, each fixed-length carrier strip falling from the carrier short strip conveying belt 5 is orderly left between two adjacent material pouring sheets on the material pouring roller 71, and the material pouring roller 71 continues to rotate to pour the fixed-length carrier strips into a gap between the rotating roller 72 and the cutting knife 73. At this time, the cutter 73 cooperates with the roller 72 to simultaneously extrude and cut the carrier short strips, and the carrier finished product formed after granulation has a small size, and can smoothly pass through the gap between the roller 72 and the cutter 73, and can be collected after being screened by the collecting hopper 8 and the screen 9 below.
The strip shifting reversing unit 4 is used for shifting each fixed-length carrier strip on the carrier short strip conveying belt 5 into the roller cutting and forming equipment 7, however, when the fixed-length carrier strip continuously falls for a long time, material blockage occurs in the roller cutting and forming equipment 7, so that cutting and granulation are blocked, and the product percent of pass is greatly reduced; or cause flash in the roll-cutting molding apparatus 7, which inevitably results in a great waste of production raw materials. Therefore, in order to avoid the above situation, so that the fixed-length carrier strip can be added into the roller-cutting forming device 7 at intervals, orderly and properly, the strip-shifting reversing unit 4 is preferably provided with a rotatable strip-shifting plate shaft 41, and the strip-shifting plate shaft 41 is controlled by the control unit 6 to drive the strip-shifting plate 42 to periodically swing back and forth along the direction perpendicular to the conveying direction of the carrier strip. Thus, as shown in fig. 3, the paddle plates 42 are periodically reciprocated at intervals, and the feeding speed is matched, so that the roll cutting and molding machine 7 can be smoothly cut by orderly and properly feeding the components.
In another embodiment, in order to improve the working efficiency of the catalyst carrier forming apparatus, the paddle shaft 41 and the paddle 42 are in a plurality of groups and the swing time interval between adjacent groups is 0.5 to 1s, preferably 0.5 s. Specifically, as shown in fig. 4, two carrier strips can be extruded simultaneously by using one strip extruder, and the strip-shifting reversing unit is provided with two strip-shifting plate shafts, that is, a first strip-shifting plate 42 'is installed on the first strip-shifting plate shaft 41', and a second strip-shifting plate 44 'is installed on the second strip-shifting plate shaft 43'; wherein, the first shifting board shaft 41 'rotates anticlockwise to drive the first shifting board 42' to shift the material on the carrier short-strip conveyer belt 5 outwards and send the material to the roller cutting forming equipment 7; the second shifting board shaft 43 'rotates clockwise to drive the second shifting board 44' to shift the material on the carrier short-strip conveyer belt 5 outwards to the roller cutting and forming device 7. Wherein, the roller cutting and forming device 7 can be two, which are respectively arranged at two sides of the carrier short-strip conveyer belt 5 and respectively cut and granulate; the same roller cutting and forming device 7 can be used, and a larger collecting hopper is arranged below the carrier short-strip conveying belt 5, so that the materials can be fed into the same roller cutting and forming device 7 for cutting and granulating.
In order to obtain good extrusion molding effect and make the extrusion smoother and more efficient, it is preferable that the extruder 1 may be a single-screw extruder, a twin-screw extruder or a ram extruder. From the viewpoint of simplifying the operation difficulty of the plodder 1 and reducing the machine maintenance probability, it is further preferable that the plodder 1 is a single-screw plodder.
The material extruded by the bar extruder 1 can have a qualified product appearance only through plasticity, and therefore, the combined forming die 2 is preferably arranged at an extrusion opening of the bar extruder 1. In addition, the combined forming die 2 is the core for determining how many continuous carrier strips can be extruded by the catalyst carrier forming device at one time, and is the central importance for improving the production and processing efficiency of the device, therefore, in order to improve the extrusion and forming efficiency as much as possible, the combined forming die 2 may be preferably a porous column type, a clover type or a teethed ball type. It is further preferable that the composite molding die 2 is a porous column type in view of simplification of the molding shape and control of the ease of subsequent cutting and granulation.
The number of the strips discharged from the combined forming die 2 is 1-4. However, from the viewpoint of facilitating the die opening process of the die and the arrangement of the drawn bar positions, the mutual influence between the adjacent drawn bars is reduced as much as possible, and it is more preferable that the number of drawn bars is 2.
The fixed-length cutting device 3 may be a cylinder cutter, an ultrasonic cutter or a rotary cutter, and of course, the fixed-length cutting device 3 may be any cutter form capable of achieving rapid cutting, which is commonly known in the art.
Similarly, in order to make the cutters on the fixed-length cutting device 3 better match with the combined forming die 2, so that the production operation beats of the fixed-length cutting device and the combined forming die are consistent, the smooth degree of the continuous carrier strip cutting forming is improved, and the overall working efficiency of the catalyst carrier forming device is ensured, the cutters with the same strip output quantity as that of the combined forming die 2 and with adjustable speed are preferably arranged on the fixed-length cutting device 3, and the cutting interval time of each cutter to the continuous carrier strip is 0.5-1 s.
In addition, in the actual production and processing process, if the length of the cut fixed-length cutting equipment 3 is too short, the size precision requirement of the subsequent roller cutting and forming equipment 7 for cutting and granulating is increased, which is neither practical nor practical; if the length of the cut-by-length cutting device 3 is too long, the size obtained after the roll cutting forming device 7 cuts and granulates still exceeds the requirement of the standard size, and at the moment, secondary cutting and granulation are needed, so that time and labor are wasted invisibly and the cost is not paid. Therefore, in order to solve the above problem, it is preferable that the length of the carrier strip cut by the fixed-length cutting device 3 is 50 to 1000 mm. Further, on this basis, in order to obtain the optimum effect of cutting and pelletizing by fixed length cutting and cutting, and to reduce the production pressure of the catalyst carrier molding apparatus, it is further preferable that the length of the carrier strip cut by the fixed length cutting device 3 is 150-500 mm.
The preferred embodiments of the present invention have been described in detail with reference to the accompanying drawings, however, the present invention is not limited to the details of the above embodiments, and the technical concept of the present invention can be within the scope of the present invention to perform various simple modifications to the technical solution of the present invention, and these simple modifications all belong to the protection scope of the present invention.
