Description

Technical Field

[0001] The invention relates to the technical field of balloon production, and in particular to automatic feeding equipment for balloon production and processing. Background Art

[0002] Balloons are mainly made of latex materials. During the production process, it is generally necessary to first configure raw materials with latex as the main ingredient. Then the latex is processed, mixed with coagulants, pigments, etc., formed through a specific mold, and then heated and cured.

[0003] In the existing balloon production process, multiple raw materials are mixed and prepared by adding and mixing equipment. Generally, the main raw material, such as latex, is first added into the equipment for stirring. After stirring and mixing for a certain period of time, other auxiliary materials, such as color pigments, coagulants and other materials are added at a set time point for further mixing.

[0004] The shortcomings of the existing balloon production feeding and mixing equipment are that: when mixing and configuring raw materials, the existing balloon production feeding and mixing equipment generally relies on manual measurement of a certain amount of ingredients at a set time point and then puts it into the mixing equipment. This operation requires a certain amount of labor intensity and is not convenient enough. Although there is also a program-controlled automatic conveying system to add materials to the mixing equipment, the general automatic conveying system must include a driving source, such as a material pump, and a conveying pipeline due to the need for material transmission. Some materials added during the feeding and mixing process of the balloon production process are colloidal or viscous materials. During the feeding process, it is easy to remain and adhere to the conveying pipeline. Moreover, as time goes by, the inner wall of the pipeline will continue to accumulate and adhere to thicker and thicker materials, thereby affecting the fluidity of the feeding pipeline, and in severe cases, it will cause blockage. Generally, it can only rely on manual disassembly of the pipeline regularly, and then check and clean the pipeline. Such operation is not convenient enough, and each inspection and cleaning needs to be carried out in the shutdown state. Summary of the invention

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] like Figure 1-Figure 11 As shown, an automatic feeding device for balloon production and processing includes a feeding barrel 2 and a quantitative weighing and conveying mechanism. The feeding barrel 2 is arranged on one side above a mixing barrel 1. Here, the mixing barrel 1 is used to mix the ingredients for producing balloons, such as latex material. The latex material is the main raw material for producing balloons. The mixing barrel 1 is equipped with a stirring member driven by a motor, and a discharge valve is arranged at the bottom of the mixing barrel 1; the bottom of the feeding barrel 2 is funnel-shaped, and a conveying pump 3 is installed to convey the raw materials in the feeding barrel 2 to the quantitative weighing and conveying mechanism. Here, the conveying pump 3 can select the corresponding pump body type according to the type of material actually conveyed. For example, if the conveyed material is a viscous material or a powder, the conveying pump 3 selects a rotor pump or a screw pump; and the output of the conveying pump 3 The end is vertically downward, and the quantitative weighing conveying mechanism is used to quantitatively weigh the conveyed raw materials and transmit them to the mixing barrel 1; the conveying pump 3 can also be equipped with a timing controller, and the running time of the conveying pump 3 is set by the timing controller, so that the conveying pump 3 automatically starts to feed the materials after a certain time from the start of mixing; the feeding equipment also includes a rotating conduit member and an automatic dredging and cleaning mechanism, the rotating conduit member is cooperatively arranged between the output end of the conveying pump 3 and the quantitative weighing conveying mechanism, the rotating conduit member includes a plurality of circumferentially distributed connecting conduits 10, and the circumferentially distributed connecting conduits 10 pass through the connecting position between the output end of the conveying pump 3 and the quantitative weighing conveying mechanism one by one by rotating, so as to prevent the blockage caused by always using one pipeline and affecting the feeding;

[0038] The automatic unclogging and cleaning mechanism is cooperatively arranged between the quantitative weighing and conveying mechanism and the rotating conduit member. The automatic unclogging and cleaning mechanism is used to clean the circumferentially distributed connecting conduits 10 one by one, that is, during the process of rotating and switching the circumferentially distributed connecting conduits 10 for use, the automatic unclogging and cleaning mechanism continuously cleans the switched connecting conduits 10.

[0039] In some specific embodiments, in combination Figure 1 and Figure 4As shown, the quantitative weighing and conveying mechanism includes a transition box 4, a weighing sensing component 22 and a reciprocating pushing mechanism. The transition box 4 is fixedly arranged on one side of the mixing barrel 1, and the transition box 4 and the mixing barrel 1 are interconnected. The weighing sensing component 22 is installed at the inner bottom of the transition box 4. The weighing sensing component 22 includes a loading platform and a weight sensing component installed at the bottom of the loading platform. The material is weighed after falling on the weighing sensing component 22, which is convenient for controlling the amount of added material; a feed port 11 aligned with the weighing sensing component 22 is provided on the top of the transition box 4; the reciprocating pushing mechanism is used to push the material inside the transition box 4 laterally, and push the material into the mixing barrel 1.

[0040] Among them, the reciprocating pushing mechanism includes an electric telescopic rod 6, a first partition push plate 5 and a second partition push plate 21. The electric telescopic rod 6 is fixedly connected to one side of the transition box 4 through a bracket, and the telescopic end of the electric telescopic rod 6 points to the inside of the transition box 4. The weighing sensing component 22 is electrically connected to the electric telescopic rod 6 and is also electrically connected to the delivery pump 3. The first partition push plate 5 and the second partition push plate 21 are distributed on both sides of the weighing sensing component 22, and the first partition push plate 5 and the second partition push plate 21 also cooperate with the inside of the transition box 4. The first partition push plate 5 is fixedly connected to the telescopic end of the electric telescopic rod 6, and the second partition push plate 21 is fixedly connected to the first partition push plate 5 through a cross bar, and the second partition The bottoms of the push plate 21 and the first partition push plate 5 are flush with the loading surface of the weighing sensing component 22. When the weighing sensing component 22 weighs the material to the corresponding weight, the matching controller is used to collect data and make a judgment. When it is judged that the set weight is reached, the controller controls the electric telescopic rod 6 to perform a telescopic movement, and at the same time, the controller sends a stop command to the conveying pump 3, so that the conveying pump 3 stops in time; when the electric telescopic rod 6 is extended, the first partition push plate 5 and the second partition push plate 21 are driven to move horizontally in the direction of the mixing barrel 1, thereby pushing the material on the weighing sensing component 22 into the mixing barrel 1, and the inner wall of the transition box 4 can also be scraped and cleaned.

[0041] In some other specific embodiments, the weighing sensor component 22 may also be disposed on the feeding barrel 2. For details, please refer to Fig.11 A support seat can be set, and the support seats can be distributed in pairs or have a U-shaped structure, and are fixedly connected to the top of the mixing barrel 1, and then a weighing sensing component 22 is installed on the support seat, and then the feeding barrel 2 is connected to the weighing sensing component 22, and at this time the delivery pump 3 is installed at the bottom of the feeding barrel 2, and there is no connection between the mixing barrel 1. When the feeding barrel 2 relies on the delivery pump 3 to transport raw materials, the weighing sensing component 22 detects that the weight is reduced. Whenever the weight decreases by a corresponding value, the corresponding controller receives instructions to control the extension of the electric telescopic rod 6.

[0042] In some specific embodiments, in combination Figure 1 and Figure 7As shown, the rotating conduit member includes a turntable 7 and a unidirectional rotating drive mechanism, and the turntable 7 is rotatably arranged on the transition box 4 of the quantitative weighing and conveying mechanism through a rotating shaft; the connecting conduit 10 is circumferentially distributed on the turntable 7, and the connecting conduit 10 passes through the turntable 7, and both ends of the connecting conduit 10 are openings, one end of the connecting conduit 10 cooperates with the output end of the conveying pump 3, and the other end cooperates with the feed port 11 of the transition box 4, that is, after each connecting conduit 10 rotates between the output end of the conveying pump 3 and the transition box 4 by relying on the turntable 7, the upper end of the connecting conduit 10 is just docked at the output end of the conveying pump 3, and the lower end is just docked at the feed port 11, and in order to ensure the sealing of the docking, a disk body with a through hole in the middle can be set at the feed port 11 and the output end of the conveying pump 3, and a sealing ring can also be installed at the through hole position of the disk body, and whenever the electric telescopic rod 6 contracts, the electric telescopic rod 6 drives the turntable 7 to rotate through the unidirectional rotating drive mechanism, so that it drives the distributed connecting conduits 10 to deflect, thereby facilitating the replacement of the next connecting conduit 10 for use.

[0043] Among them, combined Figure 2 and Fig. 9 As shown, the unidirectional rotation drive mechanism includes a pawl 13 and a ratchet 12. The telescopic end of the electric telescopic rod 6 is fixedly connected to a support frame 14. The shape of the support frame 14 can be set according to the position and shape of the transition box 4 and the turntable 7 to ensure that there is no interference between them during the movement. The pawl 13 is movably connected to the end of the support frame 14 through a rebound hinge. The ratchet 12 is coaxially fixedly connected to the turntable 7, and the pawl 13 cooperates with the ratchet 12. It should be noted that the connecting end of the pawl 13 is in contact with the end of the support frame 14, and one side of the connecting end of the pawl 13 is connected to the support frame 14 through a rebound hinge. For details, please refer to Fig.10 , so the ratchet 13 can only deflect to the other side from the original state, and cannot deflect to the other side.

[0044] When the electric telescopic rod 6 is extended, it drives the pawl 13 to move horizontally close to the ratchet 12 through the support frame 14, and when it contacts and squeezes the raised part of the ratchet 12, the pawl 13 is deflected and cannot push the ratchet 12 to rotate. It should be further explained here that in order to prevent the turntable 7 from deflecting when the pawl 13 approaches and contacts the ratchet 12, a non-slip rubber sleeve can be set on the rotating shaft connected to the turntable 7 to increase the rotation resistance; when the electric telescopic rod 6 is retracted, the pawl 13 starts to move away from the ratchet 12. During this process, the pawl 13 hooks and pulls the ratchet 12, so that the ratchet 12 deflects a certain angle, and the turntable 7 rotates synchronously with the ratchet 12. When the pawl 13 disengages from the ratchet 12, the turntable 7 just makes the originally used connecting conduit 10 disengage from the connecting position of the delivery pump 3 and the transition box 4, and then the connecting conduit 10 at the next position is just rotated to the connecting position for use, and there is no need to manually switch the connecting conduit 10.

[0045] In some specific embodiments, in combination Figures 2 to 4 As shown, the automatic unclogging and cleaning mechanism includes an elastic telescopic connecting member, a linkage steel wire 15, a lifting cleaning mechanism and a recovery box 19. The elastic telescopic connecting member is arranged between the telescopic end of the electric telescopic rod 6 and the first partition push plate 5. The linkage steel wire 15 is cooperatively connected between the lifting cleaning mechanism and the elastic telescopic connecting member. The lifting cleaning mechanism cleans the inner wall of the connecting duct 10 through a lifting movement. The recovery box 19 is used to catch the waste cleaned out of the connecting duct 10.

[0046] In some specific embodiments, specific reference is made to Figure 4 The elastic telescopic connecting member includes a connecting sleeve 8, a first limit spring 20 and a connecting guide column 9. The connecting guide column 9 is fixedly connected to the telescopic end of the electric telescopic rod 6. The connecting sleeve 8 is fixedly connected to the first partition push plate 5, and the connecting guide column 9 is slidably inserted in the connecting sleeve 8. The first limit spring 20 is connected between the connecting guide column 9 and the connecting sleeve 8, and the first limit spring 20 is stretchable. When the first limit spring 20 is in the original state, the connecting guide column 9 is received in the connecting sleeve 8. A limit block 24 matching the first partition push plate 5 is fixedly connected to the side of the transition box 4 close to the electric telescopic rod 6. When the electric telescopic rod 6 is retracted, it drives the first partition push plate 5 to move horizontally. When the first partition push plate 5 moves horizontally to the side of the transition box 4 close to the electric telescopic rod 6, it is blocked by the limit block 24 and cannot continue to move. At this time, the electric telescopic rod 6 continues to retract, which drives the connecting guide column 9 to slide relative to the connecting sleeve 8, thereby causing the first limit spring 20 to stretch and generate a rebound force.

[0047] In some specific embodiments, the lifting and cleaning mechanism includes a lifting rod 17 and a scraper ring 23. The lifting rod 17 penetrates the recovery box 19 longitudinally. The lifting rod 17 can slide up and down relative to the recovery box 19. The recovery box 19 is fixedly connected to the first partition push plate 5. A compressible second limit spring 18 is connected between the lifting rod 17 and the recovery box 19. One end of the linkage steel wire 15 is fixedly connected to the bottom of the lifting rod 17, and the other end is fixedly connected to the connecting guide column 9. It should be noted that in order to facilitate the connection between the connecting guide column 9 and the linkage steel wire 15, a protrusion 26 can be welded on one side of the connecting guide column 9 close to the telescopic end of the electric telescopic rod 6, and then the linkage steel wire 15 is connected to the connecting guide column 9 by relying on the protrusion 26. Fixed pulleys 16 that cooperate with the linkage steel wire 15 are distributed on the connecting sleeve 8 and the recovery box 19; the scraper ring 23 is fixedly connected to the top of the lifting rod 17 through a cross bar, and the scraper ring 23 cooperates with the inside of the connecting conduit 10.

[0048] When the electric telescopic rod 6 is extended, its telescopic end drives the connecting guide column 9 and the connecting sleeve 8 to move horizontally, thereby pushing the first partition push plate 5 and the second partition push plate 21 to move horizontally in the transition box 4. During this process, the connecting guide column 9 is stored in the connecting sleeve 8, and the lifting rod 17 is at the lowest position. The height position of the scraper ring 23 can move into the transition box 4 together with the first partition push plate 5; when the electric telescopic rod 6 is retracted and reset, it first drives the first partition push plate 5 to move to one side of the transition box 4 through the connecting guide column 9 and the connecting sleeve 8, and stops on the limit block 24. At this time, the scraper ring 23 is just aligned under one of the connecting conduits 10. At this time, the electric telescopic rod 6 continues to retract. Since the connecting sleeve 8 is fixedly connected to the first partition push plate 5, Therefore, it is impossible to continue to move as the electric telescopic rod 6 contracts, and the electric telescopic rod 6 can only drive the connecting guide column 9 to slide out relative to the connecting sleeve 8, and cause the first limit spring 20 to stretch. During the sliding out of the connecting guide column 9 relative to the connecting sleeve 8, the connecting guide column 9 pulls the linkage wire 15, and the linkage wire 15 relies on the steering function of the fixed pulley 16 to pull the lifting rod 17 to slide and rise relative to the recovery box 19. During this process, the second limit spring 18 is compressed to generate a rebound force, so that the lifting rod 17 drives the scraper ring 23 to rise, and penetrates into the corresponding connecting conduit 10 from bottom to top, and the scraper ring 23 scrapes the inner wall of the connecting conduit 10, thereby facilitating the scraping of the material attached to the inner wall of the connecting conduit 10, so that the material falls into the recovery box 19.

[0049] When the electric telescopic rod 6 is extended again, due to the rebound force of the first limit spring 20, the electric telescopic rod 6 drives the connecting guide column 9 to slide relative to the connecting sleeve 8 first, and during this process, the connecting sleeve 8 and the first partition push plate 5 do not move relative to the transition box 4. During this process, the linkage wire 15 is relaxed, and the lifting rod 17 is reset and descended under the rebound force of the second limit spring 18, thereby bringing the scraper ring 23 down and out of the corresponding connecting guide tube 10. When the connecting guide column 9 is completely reset relative to the connecting sleeve 8 and the first limit spring 20 returns to its original state, the scraper ring 23 has dropped to a height position lower than the top of the transition box 4, thereby facilitating the electric telescopic rod 6 to push the first partition push plate 5 to slide into the inside of the transition box 4.

[0050] It should be noted that, in order to facilitate the cleaning of the replaced connecting duct 10 during each extension and retraction process of the electric telescopic rod 6, the number of connecting ducts 10 can be set to two, and they can be symmetrically distributed on both sides of the turntable 7, and the matching size relationship between the pawl 13 and the ratchet 12 can be adjusted so that each time the pawl 13 cooperates with the ratchet 12 to drive the turntable 7 to rotate, the turntable 7 just rotates half a circle, so that the two connecting ducts 10 exchange positions.

[0051] In addition, in order to facilitate guiding the scraper ring 23 to scrape off the material falling on the inner wall of the connecting conduit 10, the scraper ring 23 can be set as an annular body with a diameter gradually decreasing from top to bottom.

[0052] It should also be noted that in order to facilitate the processing of waste collected inside the recycling box 19, a removable baffle 25 can be set on one side of the recycling box 19. Specifically, an opening can be set on the side of the recycling box 19 away from the first partition push plate 5, and card slots are set on both sides of the opening. The removable baffle 25 slides into the card slot to achieve installation. When disassembly is required, the removable baffle 25 can be directly pulled out.

[0053] It should be noted that the feeding cylinder 2, the rotating conduit member and the automatic unblocking and cleaning mechanism can be provided in multiple groups to facilitate the addition of various raw materials.

[0054] In order to facilitate the understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution is briefly described in combination with specific application scenarios:

[0055] During the mixing process of the mixing barrel 1 for mixing the ingredients for balloon production, the ingredients that need to be added midway are stored in advance in the feeding barrel 2, and the running time of the delivery pump 3 is set. When the mixing barrel 1 has been mixing the raw materials for a certain time or the delivery pump 3 is started, the delivery pump 3 delivers the ingredients in the feeding barrel 2 to the inside of the transition box 4 through the connecting conduit 10, and relies on the weighing sensor component 22 to detect the weight of the ingredients. When it is detected that the delivered material reaches the corresponding weight, the weighing sensor component 22 will feedback a signal to the matching controller, and the controller will control the electric telescopic rod 6 to perform a telescopic movement, and at the same time, the controller also relies on the controller to send a stop command to the delivery pump 3, so that the delivery pump 3 stops in time.

[0056] When the electric telescopic rod 6 is extended, it drives the first partition push plate 5 and the second partition push plate 21 to move horizontally in the direction of the mixing barrel 1, and its telescopic end drives the connecting guide column 9 and the connecting sleeve 8 to move horizontally, thereby pushing the first partition push plate 5 and the second partition push plate 21 to move horizontally in the transition box 4, thereby pushing the weighed materials to automatically enter the mixing barrel 1;

[0057] During the extension and pushing process of the electric telescopic rod 6, the lifting rod 17 is in the lowest position, and the scraper ring 23 connected to the end of the lifting rod 17 is at a height position that can move into the transition box 4 together with the first partition push plate 5; and during the extension process of the electric telescopic rod 6, it also drives the pawl 13 to move horizontally close to the ratchet 12 through the support frame 14, and when the pawl 13 contacts and squeezes the raised part of the ratchet 12, the pawl 13 deflects and cannot push the ratchet 12 to rotate.

[0058] When the electric telescopic rod 6 is retracted and reset, the pawl 13 is driven to start to move away from the ratchet 12. During this process, the pawl 13 hooks and pulls the ratchet 12, so that the ratchet 12 deflects a certain angle, and the turntable 7 rotates synchronously with the ratchet 12. When the pawl 13 is disengaged from the ratchet 12, the turntable 7 just makes the originally used connecting conduit 10 disengage from the connecting position of the delivery pump 3 and the transition box 4, and then the connecting conduit 10 at the next position is just rotated to the connecting position for use, without manual switching of the connecting conduit 10;

[0059] In addition, during the retraction of the electric telescopic rod 6, it also drives the first partition push plate 5 to move to the side of the transition box 4 through the connecting guide column 9 and the connecting sleeve 8. The first partition push plate 5 stops at the position where the limit block 24 is located. At this time, the scraper ring 23 is aligned just below the connecting guide pipe 10 that has been deflected after use. At this time, the electric telescopic rod 6 continues to retract. Since the connecting sleeve 8 is fixedly connected to the first partition push plate 5, it cannot continue to move as the electric telescopic rod 6 retracts. The electric telescopic rod 6 can only drive the connecting guide column 9 to slide out relative to the connecting sleeve 8, and cause the first limit block 24 to stop. The spring 20 is stretched, and the connecting guide column 9 slides out relative to the connecting sleeve 8. The connecting guide column 9 pulls the linkage wire 15, and the linkage wire 15 pulls the lifting rod 17 to slide and rise relative to the recovery box 19 by relying on the steering function of the fixed pulley 16. During this process, the second limit spring 18 is compressed to generate a rebound force, so that the lifting rod 17 drives the scraper ring 23 to rise, and penetrates into the corresponding connecting conduit 10 from bottom to top, and the scraper ring 23 scrapes the inner wall of the connecting conduit 10, so as to facilitate the scraping of the material attached to the inner wall of the connecting conduit 10, so that the material falls into the recovery box 19;

[0060] When the electric telescopic rod 6 is extended again, due to the rebound force of the first limit spring 20, the electric telescopic rod 6 drives the connecting guide column 9 to slide relative to the connecting sleeve 8 first, and during this process, the connecting sleeve 8 and the first partition push plate 5 do not move relative to the transition box 4. During this process, the linkage wire 15 is relaxed, and the lifting rod 17 is reset and descended under the rebound force of the second limit spring 18, thereby bringing the scraper ring 23 down and out of the corresponding connecting guide tube 10. When the connecting guide column 9 is completely reset relative to the connecting sleeve 8 and the first limit spring 20 returns to its original state, the scraper ring 23 has dropped to a height position lower than the top of the transition box 4, thereby facilitating the electric telescopic rod 6 to push the first partition push plate 5 to slide into the inside of the transition box 4.

[0061] Several embodiments of the present invention are described in detail above, but the embodiments of the present invention are not limited thereto and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
