Description

Technical Field

[0001] The utility model relates to fireworks manufacturing equipment, in particular to a push-bomb dividing linkage device for a molded fireworks outer tube production line which has high production efficiency, strong applicability, small footprint and safe use. Background Art

[0002] With the development of science and technology, the use of plant fiber, pulp, starch, calcite and other raw materials to make slurry, and the use of slurry at high temperature to form a one-time integral molding to form the outer tube of fireworks, solves the traditional fireworks production of paper cutting, rolling, gluing, drying, cutting, mud bottom, drilling, basin assembly and other complex process problems, realizes the mechanized production of fireworks outer tube, improves production efficiency and reduces labor intensity. The existing mechanized production of fireworks outer tube molding machine can not only realize one person multi-machine operation, improve the production efficiency of molded fireworks outer tube, reduce labor cost, but also improve the working environment and improve production safety. However, the existing mechanized molding machines for producing fireworks outer tubes require a total of five stations to complete the molding (the left side of the molding device station is the pre-stop station, and the right side of the molding device station is the outer tube storage and conveying station, the material distribution station and the transfer station in sequence). Since the lateral row distribution and row translation of the outer tubes are driven by a trolley (support frame) that drives a material distribution plate with several rows of material distribution hoppers and a placement plate with the same number of rows to complete the lateral row distribution and lateral row translation of the outer tubes, and since the material delivery pipe and the pushing plate are fixed in the horizontal direction (no lateral movement), there must be a transfer station on the right side of the material distribution station to place the material distribution plate. In other words, in order to complete the removal of the outer tube and the distribution of the material distribution plate, there must be three stations on the right side of the molding station to move the placement plate and the material distribution plate, so as to ensure that the material distribution plate and the placement plate are all in rows to complete the removal of the outer tube and the distribution of the material distribution plate. The area occupied by each workstation is larger than the area of ​​the material distribution plate. For an outer cylinder with six rows and seven columns in one mold, a total of 36 pieces (6 horizontally and 6 vertically), each with a cross-sectional size of 150-200 mm, each workstation occupies a length and width of approximately 1.5 meters respectively, and the total length of the fuselage is more than 5 meters). This makes it impossible to achieve horizontal installation for some factories with a width of less than 5 meters that were built in advance, and they have to install it vertically, which is not convenient for production management and cannot make full use of the factory building; for some factories with a width of more than 5 meters that were built in advance, there will be a problem that there is enough space to install one molding production line in the width direction, but not enough space to install two molding production lines. Utility Model Content

[0003] In view of the problems existing in the molded fireworks outer tube production line in the above-mentioned prior art, the utility model provides a pushing and dividing linkage device for a molded fireworks outer tube production line with a fuselage length of less than 5 meters. The molded fireworks outer tube production line can not only realize one person operating multiple machines, but also has the characteristics of high production efficiency of molded fireworks outer tubes and low labor cost. Moreover, compared with similar molded production line equipment (such as the patented-automatic molded fireworks production all-in-one machine), the fuselage length can be reduced by more than 1.5 meters, which is suitable for reasonable installation and use in various factories of different lengths. It can not only achieve reasonable layout, facilitate production organization and management, but also improve the utilization rate of factory area.

[0005] The working process of the utility model is: first preheat the mold body on the molding device to the set temperature, and then transport the slurry to the storage tank through the pressure transmission pump, start the distribution motor 34 to make the rotor metering pump 33 work, and add the slurry corresponding to the weight of the finished product output at intervals into each distribution hopper 31 in the distribution plate 30 through the rotor metering pump, and then the servo motor works, and drives the support frame to move to the left through the rotating shaft and the driving plate. When the distribution plate on the support frame moves to the molding station, the moving cylinder works, driving the gate at the bottom of the distribution hopper to open synchronously, and the slurry in the distribution hopper falls into the cavity of the lower mold body. After the gate at the bottom of the distribution hopper is closed synchronously, the support frame moves to the right direction to its original position. At the same time, the upper mold body and the lower mold body in the molding device are molded and extruded, and the set time is maintained to harden the slurry. During the hardening molding time, the solenoid valve works to open the water nozzle set on the distribution plate to clean each distribution hopper. When the hardening time is up, the upper mold body and the lower mold body on the molding device are separated. When the molded outer cylinder rises to a certain height along with the length of the upper mold body, the support frame moves to the left and the placement plate on it is located at the molding station, and the support frame stops moving. At this time, the ejection mechanism on the molding device works to synchronously eject all the outer cylinders 28 and place them on the through grooves separated from each other by the partition plate 37 on the placement plate 36. When the support frame continues to move to the right, the first row of outer cylinders on the placement plate leaves the molding station and stops moving. At this time, the push cylinder plate on the push weight material distribution linkage device at the starting position is located at the first row of outer cylinders ( Figure 1 The inner side of the first outer cylinder (inner outer cylinder) in the leftmost row of the material distribution plate, the discharge port of the feed pipe is located in the first row of the material distribution plate ( Figure 1 At the same time, the push-weight material distribution linkage device and the rotor metering pump work simultaneously to complete the longitudinal forward movement of the first outer cylinder of the first row of material distribution hoppers. At the same time, after the first row of material distribution hoppers completes the feeding of the first material distribution hopper, the push-weight material distribution linkage device moves longitudinally so that the push-tube plate on it is located on the inner side of the second outer cylinder of the first row of outer cylinders. At the same time, the material distribution valve 8 is opened under the action of the material distribution cylinder 18, and the slurry in the material delivery pipe flows from the discharge port 17 into the second material distribution hopper of the first row of the material distribution plate. The push-weight material distribution linkage device and the rotor metering pump work simultaneously again. , pushing the second outer cylinder of the first row forward one position longitudinally, and at the same time, the second sub-hopper of the first row completes the feeding, and the push-weight sub-hopper linkage device works in this cycle until all the outer cylinders in the first row are transported to the finished product conveyor belt and all the sub-hoppers in the first row have completed the feeding, after which the push-weight sub-hopper linkage device moves longitudinally back to its original position (starting position) and then moves horizontally to the right to the position of the second row of outer cylinders on the placement plate and stops moving. At this time, the push-weight sub-hopper linkage device and the rotor metering pump work at the same time, and this cycle continues until all the outer cylinders in the last row are transported to the finished product conveyor belt and all the sub-hoppers in the last row have completed the feeding.

[0006] In order to better push the outer cylinder synchronously onto the finished product conveyor belt when the pushing and dividing linkage device moves horizontally to the right, a slide that can move horizontally with the support frame is provided on the horizontal guide rail, the lower end of the slide extends out and can be connected to the pushing and cake guiding plate, a table is connected to the slide, and a push cylinder that can push the outer cylinder from the pushing and cake guiding plate to the finished product conveyor belt is fixed on one side of the table.

[0007] The utility model uses a pushing and dividing material linkage device mounted on the frame to complete the removal of each row of outer cylinders on the placing plate and the feeding of each row of dividing hoppers on the dividing plate. Therefore, when pushing and feeding, the placing plate and the dividing plate are placed in sequence on one or two stations on the right side of the molding station, and the pushing and dividing material linkage device can be used to complete the pushing and feeding. Therefore, compared with other models, one transfer station can be reduced on the right side of the molding, shortening the length of the fuselage. For a six-row six-piece model, the length of the fuselage can be shortened by more than 1.5 meters. The utility model is mounted on a fireworks outer cylinder molding machine, which can not only realize one-person multi-machine operation, but also has the characteristics of high production efficiency of molded fireworks outer cylinders and low labor cost, and is suitable for reasonable installation and use in various factories of different lengths, which can not only achieve reasonable layout, facilitate production organization and management, but also improve the utilization rate of factory area.

When a set number of molded outer tubes (each group of molded outer tubes has 4, 5 or 6, etc.) enter the finished product conveyor belt 38 under the action of the horizontal push cylinder and the cake pushing guide plate, and then enter the grouping stacking frame, the limit photoelectric sensor works to push the cylinder back, and the lifting cylinder works to lift the grouping stacking frame to the set height. The clamping plates on both sides of the clamping frame clamp the group of molded outer tubes and move along the horizontal guide rail under the action of the moving motor. The clamping frame moves up and down under the drive of the lifting motor to place the molded outer tubes in stacks on the transfer trolley, and the finished product conveyor belt is set on the spaced rollers.

The transmission shaft is meshed with a rack 19 fixed on the parallel guide rail, and a lateral moving seat 10 is arranged on the transmission shaft. The lateral moving seat is connected to a lateral moving driving device 9. The lateral moving driving device can make the support frame move back and forth horizontally on the lateral guide rail 2-2; a screw rod 25 and a guide rod 22 are arranged in both ends of the support frame on both sides of the transmission shaft through a bearing seat 23 fixed on the mounting seat, one end of the screw rod is connected to the servo motor, and a nut 7 is arranged on the screw rod. The nut on the right side of the transmission shaft is connected to the feed pipe 15 through a bridge plate (not shown in the figure) (feed pipe 15). The material tube is supported on the bridge plate), the nut on the left side of the transmission shaft is connected to the push tube plate 16 through the push tube guide sleeve 4 set on the guide rod, the push tube guide sleeve is connected to the nut, the nut moves longitudinally on the screw rod to drive the push tube guide sleeve to move longitudinally, the push tube guide sleeve moves longitudinally and drives the push tube plate to move longitudinally, so that the outer tube can move longitudinally to the finished product output belt, the longitudinal movement of the nut makes the guide sleeve on the guide rod connected to the bridge plate, so that the bridge plate also moves longitudinally, and the longitudinal movement of the bridge plate can make the material conveying pipe connected to it also move longitudinally back and forth, so that the inner part of the material conveying pipe 15 can be moved longitudinally. The slurry is added to each row of hoppers 31 on the hopper plate 30 by starting the hopper cylinder 18 to open the discharge port 17 of the hopper valve 8. The push plate and the bridge plate are synchronously linked (two screw rods are used to drive the push plate and the bridge plate to synchronize), so that each row of outer cylinders stored on the placement plate can be pushed to move. A longitudinal moving drag chain 6 is provided on one side of the support frame to move the outer cylinder longitudinally and input it to the finished product conveyor belt. At the same time, the slurry in the feed pipe can be added to each row of hoppers on the hopper plate by opening the discharge port of the feed valve.

It can complete the pushing of the outer cylinder on the placement plate and the feeding of the material distribution hopper on the material distribution plate by synchronously moving the pushing and distributing mechanisms longitudinally and transversely. Therefore, only two stations are needed to drive the placement plate and the material distribution plate on the right side of the molding station. Therefore, compared with the molded fireworks automatic production integrated machine, one station is shortened. For a 6×6 outer cylinder distribution, the machine length can be shortened by more than 1.5 meters. Therefore, except for the pushing and distributing linkage device, the contents not described and recorded in the specification are the same as those of the existing molded fireworks automatic production integrated machine. The automatic control of the working sequence and working time of each part involved in the above embodiment can be automatically controlled by the existing PLC programming technology.
