Description

Technical Field

[0001] The present invention relates to the technical field related to lead-acid battery production equipment, and more particularly to a lead paste protection transition device for a lead-acid battery vacuum paste mixing machine. Background Art

[0002] At present, vacuum paste mixing machines are commonly used in the production process of lead-acid battery paste. The advantages of vacuum paste mixing machines are uniform paste mixing and fast paste mixing speed. Usually, one vacuum paste mixing machine is equipped with two plate coating machines. To ensure continuous production, the lead paste produced by the vacuum paste mixing machine is sent to the paste storage hoppers of the two plate coating machines through movable lead paste storage hoppers. Because it is continuous production, the equipment process layout adopted is a four-layer structure. Due to the steel structure of the equipment, the gap between the paste outlet of the vacuum paste mixing machine and the bottom of the mobile paste storage hopper is too high. As a result, each time the paste is discharged, the lead paste splashes from the bottom of the paste storage hopper, causing environmental pollution and lead paste waste. The commonly used method is to install canvas or PVC material cloth in the middle transition position to block it from the middle. Although this method prevents the lead paste from splashing, the lead paste is very sticky and sticks to everything it can stick to. A lot of lead paste will stick to the canvas or PVC material. Over time, the stuck lead paste will harden and scatter to the lower coating machine during the production process, seriously affecting the production quality of the coated board. It is also difficult to clean.

[0003] Chinese patent publication number CN209150268U, publication date July 23, 2019, the application discloses a lead paste recovery device, including: a lead paste collection trough; a first downward dialing mechanism, arranged in the lead paste collection trough; a first horizontal discharge mechanism, arranged in the lead paste collection trough and located below the first downward dialing mechanism; a vertical feeding mechanism, the lower end of which is connected to the first discharge port of the lead paste collection trough, and a second discharge port is opened on the top; it also includes: a transition collection trough, located below the second discharge port, and a third discharge port located above the lead paste hopper is provided on one side; a guide plate, connecting the second discharge port and the trough edge of the transition collection trough; a second downward dialing mechanism, arranged in the transition collection trough; a second horizontal discharge mechanism, arranged in the transition collection trough and located below the second downward dialing mechanism, discharging material to the third discharge port; the present invention can effectively reduce the possibility of blockage of the recovered lead paste and make the operation of the device more stable. Summary of the Invention

[0004] The present invention overcomes the problem that when canvas or PVC cloth is installed at the intermediate transition position for intermediate blocking in the prior art, a lot of lead paste is easily stuck on the canvas or PVC material due to its high viscosity, and it is inconvenient to clean. The stuck lead paste will harden over time, and the hardened lead paste will scatter to the lower plate coating machine during the production process, seriously affecting the coating and production quality. A lead paste protection transition device for a lead-acid battery vacuum paste machine is provided, which can realize self-cleaning and sealing between the paste outlet and the movable paste hopper.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions: a lead paste protective transition device for a lead-acid battery vacuum paste machine, comprising a mounting steel structure, on which a vacuum paste machine and a movable paste bucket are mounted, a transition device between the vacuum paste machine and the movable paste bucket, the transition device comprising a mounting seat and a transition cylinder rotatably arranged on the mounting seat, a cylinder wall driving device being provided between the mounting seat and the transition cylinder, and a cylinder wall scraper connected to the mounting seat being provided in the transition cylinder.

[0006] The present invention overcomes the drawback of existing vacuum paste mixing machines, which often require a transition device installed between the paste outlet and the mobile paste storage hopper, which is non-self-cleaning. As the lead paste produced by the vacuum paste mixing machine is fed into the mobile paste hopper, the transition device activates. Because it incorporates a built-in cylinder wall drive, even if lead paste splashes onto the inner wall of the transition cylinder, it is removed by a cylinder wall scraper and simultaneously falls into the lower plate coating machine, preventing the generation of dry paste that could affect product quality. Both the transition cylinder and the cylinder wall scraper are made of 304 stainless steel, offering a certain degree of corrosion resistance and eliminating potential product quality risks.

[0007] Preferably, the drum wall drive device includes a drive motor fixedly mounted on the mounting base, a transmission gear mounted on the output end of the drive motor, and a rack ring circumferentially disposed on the outer wall of the transition drum, with the transmission gear and the rack ring meshingly connected. When the transition drum is activated, the drive motor is activated, which in turn drives the transmission gear to rotate. This rotation of the transmission gear drives the rack ring and the transition drum to rotate synchronously, thereby cooperating with a fixed drum wall scraper to achieve a self-cleaning function for the transition drum.

[0008] Preferably, the mounting seat is provided with a boss in a circular ring structure, with a plurality of positioning blocks arranged in a circumferential array on the boss. Each positioning block is provided with a rotating wheel 1 that contacts the underside of the rack ring. The transition barrel is mounted within the boss, and a through hole communicates with the inner cavity of the transition barrel, facilitating its positioning and rotation. The design of the matching structure between the positioning blocks and the rotating wheel 1 helps reduce friction between the mounting seat and the transition barrel during rotation and allows for positioning of the underside of the transition barrel.

[0009] Preferably, the transition tube is provided with a plurality of wall positioning blocks on its outer circumference, on which a second runner is provided, which contacts the outer wall of the transition tube. The design of the matching structure of the wall positioning blocks and the second runner can realize the positioning of the lower side of the transition tube.

[0010] Preferably, the transition tube is provided with a plurality of inspection doors, which facilitate inspection and cleaning of the interior of the transition tube.

[0011] Preferably, the drum wall scraper comprises a fixed section and a scraping section. The scraping section is provided with an inclined scraping surface, the end of which is close to the inner wall of the transition drum. The fixed section and the scraping section are fixedly mounted on the mounting steel structure on the bottom side of the vacuum paste mixing machine.

[0012] Preferably, the barrel wall scraper is provided with a secondary paste hanging mechanism, the secondary paste hanging mechanism includes a wall scraper arranged between the fixed section and the scraper section, a plurality of fixed plates are provided on the outer wall of the transition barrel, a slit scraper is provided inside the wall scraper, and a first drive mechanism and a second drive mechanism are provided on the fixed section; four fixed plates are provided, which are located above the detection door and are equidistantly arranged along the circumferential direction of the outer wall of the transition barrel; the fixed plates are provided with an arc surface on the side away from the transition barrel.

[0013] The first drive mechanism, the fixed plate is used to trigger the start of the first drive mechanism. When the first drive mechanism is started, the slit scraper moves along the barrel wall with the back surface of the scraper close to the inner wall of the transition barrel, and then extends into the slit between the inspection door and the upper and lower sides of the transition barrel to scrape out the lead paste;

[0014] The second drive mechanism, using the wall-adhering scraper, can scrape away any lead paste that remains between the inner wall of the transition tube and the wall scraper. When the wall scraper scrapes away spattered lead paste from the inner wall of the transition tube for a prolonged period of time, a gap can easily form between the scraper and the inner wall of the transition tube. If this gap is not cleaned, it can adhere to the inner wall of the transition tube, forming a layer of lead paste that then solidifies, making it difficult to clean the inner wall of the transition tube and opening the inspection door.

[0015] Preferably, the first drive mechanism comprises a hydraulic tube 1 and a plurality of hydraulic tubes 2, wherein a connecting tube assembly is connected between the hydraulic tube 1 and the hydraulic tube 2. The slider 1 is slidably disposed within the hydraulic tube 1, and the slider 2 is slidably disposed within the hydraulic tube 2. The slider 2 contacts the connecting section on the back side of the slit scraper, and a telescopic spring is disposed between the slit scraper and the fixed section. Both the hydraulic tube 1 and the hydraulic tube 2 are filled with hydraulic oil. When the fixed plate rotates with the transition cylinder to a position in contact with the slider 1, the transition plate pushes the slider 1 to slide, causing the hydraulic oil in the hydraulic tube 1 near the slider 1 to flow through the connecting tube assembly and then into the two hydraulic tubes 2. This pushes the slider 2 to slide, thereby driving the slider 2 to push the connecting section. The connecting section drives the slit scraper to slide along the scraping end of the barrel wall and then extend into the upper and lower slits between the inspection door and the transition cylinder to scrape the lead paste. This structure prevents the inspection door from accumulating lead paste in the slit, thereby preventing the accumulated lead paste from solidifying and becoming difficult to open for inspection.

[0016] Preferably, the second drive mechanism includes a hydraulic box, a piston cylinder mounted on the hydraulic box, a hydraulic push plate slidably mounted within the hydraulic box, a third hydraulic tube, and a fourth hydraulic tube. A connecting tube connects the third hydraulic tube and several fourth hydraulic tubes. One end of the third hydraulic tube is connected to the hydraulic box, and a third slider is slidably mounted on the other end of the fourth hydraulic tube. The third slider is fixedly connected to the wall scraper. Hydraulic oil is provided in both the hydraulic box and the third hydraulic tube. A block is fixedly mounted on the wall of the wall scraper near the slit scraper. A chute is provided within the slit scraper. The block slides within the chute. A gap is provided between the block and the chute, and the gap is close to the scraping end of the barrel scraper. When it is necessary to scrape the lead paste in the gap between the cylinder wall scraper and the inner wall of the transition cylinder, the piston cylinder is started, and the piston push rod on the piston cylinder drives the hydraulic push plate to move, so that the hydraulic oil in the hydraulic box flows out through the hydraulic pipe three, and then pushes the slider three to slide. The sliding of the slider three drives the wall scraper to slide along the scraping end of the cylinder wall scraper to clean and scrape the lead paste in the gap between the cylinder wall scraper and the inner wall of the transition cylinder; at the same time, the sliding of the wall scraper drives the gap scraper to slide together. Due to the effect of the gap, when the wall scraper is moved out, the blade edge of the gap scraper is flush with the blade edge of the gap scraper, which is convenient for removing the lead paste on the cylinder wall.

[0017] Preferably, the slider 1 is provided with a sensor 1, and the fixed section is provided with a sensor 2. The contact detection between the sensor 1 and the sensor 2 can indirectly control the driving time of the piston cylinder. The sensor 1 is fixedly mounted on the inner wall of the slider 1, and the fixed section is provided with a sliding cavity. The slider 1 is arranged in the sliding cavity, and the inner wall of the sliding cavity is provided with a sensor 2. When the slider 1 slides into the sliding cavity 1, the sensor 2 contacts and senses the sensor 1, thereby identifying the rotation position of the transition barrel. When the inspection door gap is completed four times, it represents that the transition barrel has rotated one circle. At this time, the piston cylinder can be controlled to drive and clean the lead paste in the gap between the barrel wall scraper and the inner wall of the transition barrel. When the inspection door gap is cleaned after four times, the piston cylinder is driven to reset and move, thereby achieving indirect cleaning, thereby protecting the scraper to a certain extent, and thus improving the service life of the equipment. According to the number of inspections set by the system, multiple cleaning schemes can be realized.

[0018] Compared with the prior art, the beneficial effect of the present invention is that the lead paste protection transition device overcomes the problem of lead paste splashing everywhere due to the high height difference between the paste outlet of the vacuum paste mixing machine and the bottom of the mobile paste storage hopper due to the steel structure of the equipment installation. At the same time, the transition device can also be sealed and self-cleaned. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0028] The following is a further detailed description of the technical solution of the present invention through specific embodiments and in conjunction with the accompanying drawings: Example 1: A lead paste protective transition device for a lead-acid battery vacuum paste mixing machine (see attached Figure 1-4 ), including a mounting steel structure 100, on which a vacuum paste mixing machine 101 and a mobile paste bucket 102 are mounted, a transition device 1 between the vacuum paste mixing machine 101 and the mobile paste bucket 102, the transition device 1 including a mounting seat 2 and a transition tube 3 mounted on the mounting seat 2, a cylinder wall driving device 4 provided between the mounting seat 2 and the transition tube 3, a cylinder wall scraper 5 connected to the mounting seat 2 provided in the transition tube 3. A boss 6 in a circular ring structure is provided on the mounting seat 2, and a through hole communicating with the inner cavity of the boss 6 is provided on the mounting seat 2. The transition tube 3 is mounted in the boss 6, and the through hole is communicated with the inner cavity of the transition tube 3, facilitating the positioning and rotation of the transition tube 3. The cylinder wall driving device 4 includes a driving motor 7, a transmission gear 8 provided on the output shaft of the driving motor 7, a rack ring 9 fixedly provided circumferentially on the outer wall of the transition tube 3, and the transmission gear 8 and the rack ring 9 are meshed and connected. The rack ring 9 is provided on the upper side of the boss 6.

[0029] The present invention overcomes the drawback of the existing vacuum paste mixing machine's transition device installed between the paste outlet and the mobile paste storage hopper, which cannot be self-cleaned. The transition tube and the tube wall scraper are both made of 304 stainless steel, which has a certain degree of corrosion resistance and will not cause quality problems for the product.

[0030] Workflow

[0031] When the lead paste produced by the vacuum paste mixing machine is being fed into the mobile paste bucket, the transition device 4 is started. When the transition device 4 is started, the drive motor 7 is started, and the drive motor 7 drives the transmission gear 8 to rotate. The transmission gear 8 rotates and drives the rack ring 9 and the transition cylinder 3 to rotate synchronously, and then cooperates with the fixedly installed cylinder wall scraper 5 to realize the self-cleaning function of the transition device 4; even if the lead paste splashes onto the inner wall of the transition cylinder 3, it will be removed by the cylinder wall scraper 5, and the scraped lead paste will fall into the lower plate coating machine at the same time, and no dry paste will be produced to affect the product quality.

[0032] Example 2:

[0033] This example is based on the embodiment 1 and is equipped with eight positioning blocks 10 (see the attached Figure 1-3 ), eight positioning blocks 10 are fixedly mounted on the upper wall of the boss 6, and the positioning blocks 10 are arranged equidistantly around the circumference. Rotating wheels 11 are mounted on the positioning blocks 10 and rotatably contact the lower side of the rack ring 9. The design of the coordinated structure of the positioning blocks 10 and the rotating wheels 11 helps reduce friction between the mounting base 2 and the transition barrel 3 during rotation, and can achieve positioning of the lower side of the transition barrel.

[0034] Example 3:

[0035] This example is based on Example 1 and is equipped with four additional fixing devices (see attached Figure 1-3 ) is mounted on the mounting base. The fixing device includes a fixing plate 12 and a connecting rod 13 connecting the fixing plate and the mounting base. This fixing device is used to securely mount the transition device. The fixing plate and the connecting rod cooperate to securely mount the transition device to the mounting steel structure near the mobile paste hopper.

A second runner 15 is mounted on the cylinder wall positioning blocks 14, which contacts the outer wall of the transition cylinder. The design of the coordinated structure of the cylinder wall positioning blocks and the second runner ensures the positioning of the lower side of the transition cylinder.

[0038] Example 5:

[0039] This example is based on the embodiment 1 and is equipped with four additional inspection doors 16 (see the attached Figure 1-3 ), an inspection door 16 is arranged on the transition tube 3 along the circumferential direction, and a handle 17 is fixed on the inspection door. The inspection port facilitates the inspection and cleaning of the interior of the transition tube.

[0040] Example 6:

[0041] The drum wall scraper includes a fixed section 18 and a scraper section 19 (see attached Figure 1-4 ), a scraping surface 20 is provided on the scraper segment, with the end of the scraping surface close to the inner wall of the transition tube 3. The cross section of the scraper segment is a triangular structure. The fixed segment is a barbed hook structure.

[0042] Example 7:

[0043] This example is based on the fifth embodiment and is equipped with a secondary paste coating mechanism (see the attached Figure 1-7 ), the secondary paste coating mechanism includes a wall scraper 21 arranged between the fixed section and the scraper section, four fixed plates 22 are provided on the outer wall of the transition cylinder 3, the wall scraper 21 is slidably mounted with two slit scrapers 23, and the fixed section is provided with a first drive mechanism and a second drive mechanism;

[0044] The first driving mechanism includes a hydraulic tube 1 24 and two hydraulic tubes 25. A connecting pipe assembly 26 is connected between the hydraulic tube 1 and the hydraulic tube 2. A slider 1 27 is provided for sliding inside the hydraulic tube 1, and a slider 28 is provided for sliding inside the hydraulic tube 2. The slider 2 28 is in contact with the connecting section 44 on the back blade side of the slit scraper. Two spring chambers 29 are provided in the wall body of the wall scraper close to the side of the barrel wall scraper. The slider 2 is fixedly installed on the back blade end of the slit scraper. A telescopic spring 30 is provided between the spring chamber 29 and the connecting section 40. The telescopic spring is used to automatically reset the slit scraper under the elastic force of the telescopic spring when the fixed plate is out of contact with the slider 1.

[0045] The first drive mechanism, the fixed plate 22 is used to trigger the first drive mechanism. When the first drive mechanism is started, the gap scraper 23 approaches the inner wall of the transition tube 3 along the back surface of the scraper 5 on the wall, and then extends into the gap between the inspection door 16 and the upper and lower sides of the transition tube to scrape out the lead paste;

[0046] The second drive mechanism includes a hydraulic box 31, a piston cylinder 32 mounted on the hydraulic box, a hydraulic push plate 33 slidably mounted within the hydraulic box, a third hydraulic tube 34, and a fourth hydraulic tube 35. A connecting tube 36 connects the third hydraulic tube 34 and several fourth hydraulic tubes 35. One end of the third hydraulic tube 34 is connected to the hydraulic box 31, and a third slider 37 is slidably mounted on the other end of the fourth hydraulic tube 35. The third slider 37 is fixedly connected to the wall scraper. Hydraulic oil is supplied to both the hydraulic box and the third hydraulic tube. A stopper 38 is fixedly mounted on the wall of the wall scraper near the slit scraper. A slot 39 is provided within the slit scraper. The stopper slides within the slot, leaving a gap 40 between the stopper and the slot, the gap being close to the scraping end of the barrel scraper.

[0047] The second driving mechanism can scrape off the lead paste that is not removed between the inner wall of the transition tube and the tube wall scraper through the wall scraper.

[0048] Workflow:

[0049] When the transition plate rotates with the transition cylinder to a position in contact with the slider one, the transition plate pushes the slider one to slide, causing the hydraulic oil in the hydraulic pipe one close to the slider one side to flow through the connecting pipe assembly and then flow into the two hydraulic pipes two, which then pushes the slider two to slide, thereby driving the slider two to push the connecting section, and the connecting section drives the gap scraper to slide out along the scraping end of the scraper on the cylinder wall, and then extends into the upper and lower side gaps between the inspection door and the transition cylinder to scrape the lead paste; this structure can prevent the inspection door from accumulating lead paste in the gap, thereby avoiding the problem of the accumulated lead paste solidifying and being difficult to open for inspection;

[0050] When it is necessary to scrape the lead paste in the gap between the cylinder wall scraper and the inner wall of the transition cylinder, the piston cylinder is started, and the piston push rod on the piston cylinder drives the hydraulic push plate to move, so that the hydraulic oil in the hydraulic box flows out through the hydraulic pipe three, the connecting pipe and the two hydraulic pipes four in sequence, and then pushes the slider three to slide. The sliding of the slider three drives the wall scraper to slide along the scraping end of the cylinder wall scraper to clean and scrape the lead paste in the gap between the cylinder wall scraper and the inner wall of the transition cylinder; at the same time, the sliding of the wall scraper drives the gap scraper to slide together. Due to the effect of the gap, when the wall scraper is moved out, the blade edge of the gap scraper is flush with the blade edge of the gap scraper, which is convenient for removing the lead paste on the cylinder wall.

[0051] Example 8:

[0052] This example is based on Example 7 and adds a detection mechanism (see Appendix Figure 6 ), the detection mechanism includes sensor 1 41 and sensor 2 42. Contact detection between sensor 1 and sensor 2 indirectly controls the piston cylinder's actuation time. Sensor 1 is fixedly mounted on the inner wall of slider 1. The fixed section defines a sliding cavity 43. Slider 1 is disposed within the cavity, and sensor 2 is located on the inner wall of the cavity.

[0053] Workflow:

[0054] When slider one slides into sliding cavity one, sensor two contacts and senses sensor one, thereby identifying the rotation position of the transition cylinder. When the inspection door gap is completed four times, it represents that the transition cylinder rotates one circle. At this time, the piston cylinder can be controlled to drive to clean and scrape the lead paste in the gap between the cylinder wall scraper and the inner wall of the transition cylinder; when it is checked again that the inspection door gap is cleaned after four times, the piston cylinder is driven to reset and move, thereby realizing indirect cleaning, thereby protecting the scraper to a certain extent, thereby increasing the service life of the equipment; according to the number of inspections set by the system, a variety of cleaning schemes can be realized.
