Description

Technical Field

[0001] This application relates to the field of adhesive processing, and in particular to an adhesive reaction apparatus capable of precise dispensing. Background Technology

[0002] In the adhesive production field, traditional feeding devices generally suffer from numerous problems. Early, simple feeding equipment relied heavily on manual operation, with workers using experience and simple tools such as spoons and funnels to add adhesive raw materials to the reaction vessel. This method was not only inefficient but also had extremely poor feeding accuracy, making it difficult to ensure consistent amounts of raw materials added each time. This resulted in large fluctuations in the quality of adhesive products across different batches, failing to meet the stringent requirements of modern industry for product stability and consistency. With the advancement of industrialization, some semi-automatic feeding devices emerged. While these devices reduced the manual burden to some extent by using mechanical structures to assist feeding, such as screw pushers or piston pushers, they still had shortcomings. On the one hand, the initial material collection process was not precise enough, and raw materials tended to accumulate and scatter around the inlet, causing waste and affecting the accuracy of subsequent feeding. On the other hand, in terms of quantitative control, due to the limitations of the mechanical structure's precision and the lack of effective real-time monitoring methods, it was difficult to achieve high-precision feeding, especially when dealing with small-dose, high-precision adhesive formulations, where deviations were even more pronounced.

[0003] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: Many existing feeding devices rely on manual experience or simple mechanical structures for feeding. During the material collection stage, some devices lack effective structures for guiding and gathering the material. Material easily accumulates or scatters around the inlet, failing to effectively collect all material into the feeding area. This not only wastes material but also affects subsequent feeding operations, leading to inaccurate feeding amounts. Utility Model Content

[0004] In view of the shortcomings of the prior art and in order to solve the problems mentioned in the background art, this application provides an adhesive reaction device that can accurately add materials.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an adhesive reaction device capable of precise material feeding, comprising a base, a precise material feeding mechanism being provided on the top of the base, and a first servo motor being provided on the top of the precise material feeding mechanism;

[0006] The precision feeding mechanism includes a support column, a top plate, a rotating shaft, a scraper, a metering chamber shell, a metering chamber body, and an annular baffle. The support column is fixedly installed on the top of the base, and the top plate is fixedly installed on the top of the support column. The rotating shaft is movably installed on the bottom of the top plate, and the scraper is fixedly connected to one side of the rotating shaft. The metering chamber shell is movably connected to the bottom of the scraper. The metering chamber body is penetrated through the top of the metering chamber shell, and the annular baffle is fixedly connected to the outer wall of the metering chamber shell. The metering chamber shell serves as the external protection and support structure for the metering chamber body. It not only protects the internal metering chamber body from external collisions and interference, but its annular baffle also effectively prevents material from splashing and overflowing during the scraping process, ensuring that the material is concentrated near the metering chamber and improving feeding accuracy. The metering chamber body is the core component for achieving precise metering feeding. Its internal space is precisely designed to hold the binder material to be added for the reaction. Through cooperation with the pusher plate, it accurately controls the volume or weight of each feeding, meeting the strict requirements of different reaction processes for the amount of binder used. Annular baffle: It is tightly attached to the outer wall of the metering chamber and forms a barrier during the scraping process to prevent the material from falling to other parts of the device. Especially during high-speed scraping, it firmly restricts the material around the metering chamber, ensuring that the material enters the metering chamber without any leakage, laying the foundation for subsequent accurate feeding.

[0007] Optionally, the precision feeding mechanism further includes a push rod, a push plate, a driven plate, a limit rod, a lead screw, and a transmission gear. The push rod is disposed inside the metering cavity body. The top of the push rod is fixedly connected to the push plate, and the bottom of the push rod is fixedly connected to the driven plate. A threaded hole is opened at the axis of the driven plate, and a limit rod is movably sleeved inside the threaded hole. The bottom of the limit rod is fixedly connected to the lead screw, and the bottom of the lead screw is fixedly connected to the transmission gear. The transmission gear, as an intermediate link in power transmission, meshes with the driven gear, transmitting the power from the driven gear to the lead screw, driving the lead screw to rotate, and thus driving the entire feeding system to operate, ensuring the stability and precision of power transmission, and achieving precise control of the feeding amount.

[0008] Optionally, the precision feeding mechanism further includes a driven gear, a drive gear, a second servo motor, a positioning frame, an indicator arrow, and a measuring groove. The driven gear meshes with one side of the drive gear, and the drive gear meshes with the same side. The drive gear is fixedly mounted on the output end of the second servo motor. The positioning frame is movably connected to the top of the driven gear and the drive gear. The indicator arrow is fixedly connected to one side of the driven plate, and the measuring groove is located on one side of the support column. The driven gear meshes with the drive gear on one side and with the drive gear on the other, serving as a transition and speed change mechanism. It transmits the power output from the second servo motor to the drive gear via the drive gear and adjusts the speed and torque according to the gear ratio to meet the requirements of the feeding system. The drive gear is fixed to the output end of the second servo motor, directly receiving the motor power and transmitting the high-speed rotating power to the driven gear. It acts as the starting drive component of the gear transmission chain, injecting energy into the entire feeding power transmission system.

[0009] Optionally, the indicator arrow is movably connected to one side of the support column and the indicator arrow is aligned with the measuring groove, and the positioning bracket is fixedly installed on the top of the base.

[0010] Optionally, the rotating shaft is fixedly installed at the bottom of the output end of the first servo motor, the cross-sectional shape of the scraper is arched, and the opening direction of the scraper is the same as the rotation direction of the rotating shaft.

[0011] Optionally, the pusher plate is movably connected inside the metering cavity body, and the height of the pusher rod is the same as the depth of the metering cavity body.

[0012] Optionally, the bottom of the limiting rod is movably connected to the inside of a through hole at the center of the base, and the lead screw is threaded into the inside of a threaded hole at the center of the driven plate.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] 1. This utility model, by setting up a precise feeding mechanism, provides a precise space for materials to be contained in the quantitative cavity of the precise feeding mechanism. With the help of push rods, push plates and other components, it can accurately push materials according to production needs. The volume or weight of each feeding is highly consistent, which effectively avoids the problem of affecting the quality of adhesive products due to too much or too little feeding, ensures that the chemical reaction proceeds as expected, and improves the product qualification rate.

[0015] 2. This invention utilizes the unique design of the scraper blade, whose arched structure and coordinated operation with the rotating shaft can efficiently scrape scattered materials into the metering chamber, minimizing material residue and waste. The annular baffle further prevents material overflow, allowing the material to fully participate in the reaction and reducing production costs. Attached Figure Description

[0021] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0022] This application discloses an adhesive reaction device capable of precise material addition.

[0023] Please see Figure 1 A precise feeding adhesive reaction device includes a base 1, a precise feeding mechanism 3 is provided on the top of the base 1, and a first servo motor 2 is provided on the top of the precise feeding mechanism 3.

[0024] Please see Figures 2 to 4 The precision feeding mechanism 3 includes a support column 301, a top plate 302, a rotating shaft 303, a scraper 304, a metering chamber shell 305, a metering chamber body 306, and an annular baffle 307. The support column 301 is fixedly installed on the top of the base 1. The top plate 302 is fixedly installed on the top of the support column 301. The rotating shaft 303 is movably installed on the bottom of the top plate 302. The scraper 304 is fixedly connected to one side of the rotating shaft 303. The metering chamber shell 305 is movably connected to the bottom of the scraper 304. The metering chamber body 306 is opened through the top of the metering chamber shell 305. The annular baffle 307 is fixedly connected to the outer wall of the metering chamber shell 305.

[0025] The precision feeding mechanism 3 also includes a push rod 308, a push plate 309, a driven plate 310, a limit rod 311, a lead screw 312, and a transmission gear 313. The push rod 308 is located inside the metering cavity body 306. The top of the push rod 308 is fixedly connected to the push plate 309, and the bottom of the push rod 308 is fixedly connected to the driven plate 310. A threaded hole is opened at the axis of the driven plate 310, and the limit rod 311 is movably sleeved inside the threaded hole. The bottom of the limit rod 311 is fixedly connected to the lead screw 312, and the bottom of the lead screw 312 is fixedly connected to the transmission gear 313.

[0026] The precision feeding mechanism 3 also includes a driven gear 314, a drive gear 315, a second servo motor 316, a positioning frame 317, an indicator arrow 318, and a measuring groove 319. The driven gear 314 is meshed with the drive gear 313 on one side, and the drive gear 315 is meshed with the driven gear 314 on one side. The drive gear 315 is fixedly installed at the output end of the second servo motor 316. The positioning frame 317 is movably connected to the top of the driven gear 314 and the drive gear 315. The indicator arrow 318 is fixedly connected to one side of the driven plate 310, and the measuring groove 319 is opened on one side of the support column 301.

[0027] The indicator arrow 318 is movably connected to one side of the support column 301, and the indicator arrow 318 fits into the measuring groove 319. The positioning bracket 317 is fixedly installed on the top of the base 1.

[0028] The rotating shaft 303 is fixedly installed at the bottom of the output end of the first servo motor 2. The cross-sectional shape of the scraper 304 is arched, and the opening direction of the scraper 304 is the same as the rotation direction of the rotating shaft 303.

[0029] The pusher plate 309 is movably connected inside the metering cavity body 306, and the height of the push rod 308 is the same as the depth of the metering cavity body 306.

[0030] The bottom of the limit rod 311 is movably connected to the inside of the hole that runs through the center of the base 1, and the lead screw 312 is threaded into the inside of the threaded hole at the center of the driven plate 310.

[0031] Further explanation is needed:

[0032] 1. Material collection and import section

[0033] Support column 301 and top plate 302: Support column 301 stands firmly on base 1, providing strong support to top plate 302 and ensuring that top plate 302 can stably support rotating shaft 303 and its associated scraper 304. This stable structural design provides a reliable foundation for subsequent scraping operations and prevents inaccurate scraping or material spillage due to structural loosening.

[0034] Rotating shaft 303 and scraper 304: The first servo motor 2 drives the rotating shaft 303 to rotate, which in turn drives the scraper 304 to operate. The scraper 304 has an arched cross-section and its opening direction is in line with the rotation direction of the rotating shaft 303. This design is very ingenious. When the material accumulates around the outer shell 305 of the metering chamber, the rotating scraper 304, like a skillful hand, can quickly and efficiently gather the material along the arched slope and accurately guide it into the top opening of the metering chamber body 306. This greatly improves the efficiency of material collection, reduces material residue and waste, and ensures that the required material for each reaction can enter the metering chamber in sufficient quantity.

[0035] Metering chamber housing 305 and annular baffle 307: The metering chamber housing 305 not only provides a protective barrier for the metering chamber body 306, but the annular baffle 307 on its outer wall also plays a crucial role. During the scraping process, the material is easily splashed in all directions due to centrifugal force or other factors. The annular baffle 307 acts like a sturdy wall, firmly locking the material and concentrating it near the metering chamber, creating favorable conditions for accurate feeding and avoiding material loss and pollution to the surrounding environment.

[0036] 2. Material delivery and precision control section

[0037] Push rod 308, pusher plate 309, and driven plate 3010: Push rod 308 penetrates the metering chamber body 306, and the top pusher plate 309 is adapted to the inner wall of the metering chamber body 306, allowing for a tight fit while also sliding flexibly. When material needs to be added, the driven plate 3010, connected to push rod 308 at the bottom, drives push rod 308 upward under the drive of components such as lead screw 312. Pusher plate 309 then smoothly pushes the material out of metering chamber body 306, achieving precise metering and ensuring consistent material quantity added each time, thus ensuring reaction stability and product quality consistency.

[0038] Limiting rod 311 and lead screw 312: The bottom of the limiting rod 311 is embedded in the center hole of the base 1 and is concentrically engaged with the threaded hole of the driven plate 310, providing precise guidance and limiting for the driven plate 310. When the lead screw 312 rotates to drive the driven plate 310 to move up and down, the limiting rod 311 ensures that the driven plate 310 can only move stably in the vertical direction, avoiding tilting or deviation of the push rod 308, thereby ensuring the accuracy of the pushing direction and ensuring that the material is accurately injected into the reaction area.

[0039] The transmission gear 313, driven gear 314, drive gear 315, and second servo motor 316 form the core power chain for achieving precise material feeding control. The second servo motor 316 outputs power to the drive gear 315, which in turn drives the driven gear 314 to rotate. The driven gear 314 then drives the transmission gear 313 to rotate, ultimately rotating the lead screw 312. By designing different gear ratios, the speed and torque can be flexibly adjusted to precisely control the lifting speed and force of the driven plate 310, adapting to different material characteristics such as viscosity differences and varying feeding amounts. This allows for precise control of both micro-feeding in fine chemical applications and rapid, large-volume feeding in large-scale production.

[0040] Indicator arrow 318 and measuring groove 319: Indicator arrow 318 is fixed to one side of driven plate 310 and fits against measuring groove 319 on support column 319. As driven plate 310 moves up and down, indicator arrow 318 slides synchronously in measuring groove 319. Operators can intuitively and clearly grasp the advancement status of push rod 308 and push plate 309 in metering cavity body 306 by simply looking at the position of indicator arrow 318 on measuring groove 319, monitor the feeding process in real time, and promptly detect and correct any possible feeding deviations, greatly improving the convenience of operation and the accuracy of feeding.

[0041] The working principle of the above embodiments is as follows:

[0042] 1. Material collection and preparation stage

[0043] First, after the device is started, the first servo motor 2 starts working, and its output end drives the rotating shaft 303, which is fixedly connected to it, to rotate. Since a scraper 304 is fixedly connected to one side of the rotating shaft 303, and the cross-sectional shape of the scraper 304 is arched, and the opening direction is the same as the rotation direction of the rotating shaft 303, as the rotating shaft 303 rotates, the scraper 304 will scrape the surrounding material like a "shovel".

[0044] The scraper 304 gathers and pushes the material toward the direction of the metering chamber shell 305, while the annular baffle 307 fixedly connected to the outer wall of the metering chamber shell 305 plays a blocking role. It can prevent the material from splashing out in all directions during the scraping process, so that the material can be accurately gathered at the upper opening of the metering chamber body 306 through the top of the metering chamber shell 305, thus storing the material for the subsequent metering feeding process.

[0045] 2. Quantitative feeding stage

[0046] Next, the second servo motor 316 starts running, and the drive gear 315 fixed at its output end begins to rotate. The drive gear 315 meshes with the driven gear 314, and the driven gear 314 meshes with the transmission gear 313. Through this gear transmission system, power is transmitted from the second servo motor 316 to the transmission gear 313 in sequence.

[0047] The transmission gear 313 is fixedly connected to the lead screw 312, and the thread of the lead screw 312 is threaded into the threaded hole at the center of the driven plate 310. When the transmission gear 313 drives the lead screw 312 to rotate, due to the engagement between the threaded hole at the center of the driven plate 310 and the lead screw 312, as well as the limiting and guiding effect of the limiting rod 311 on the driven plate 310, the bottom of the limiting rod 311 is movably connected to the inside of the through hole at the center of the base 1, and the driven plate 310 will move vertically up and down along the limiting rod 311.

[0048] The up-and-down movement of the driven plate 310 drives the push rod 308, which is fixedly connected to it, to move synchronously. The push plate 309, which is fixedly connected to the top of the push rod 308, is movably connected inside the metering cavity body 306. When the push rod 308 moves up or down, the push plate 309 slides up or down accordingly inside the metering cavity body 306, thereby pushing the material that has been collected inside the metering cavity body 306 and pushing the material out of the metering cavity body 306 according to the set amount, thus achieving precise feeding operation.

[0049] Throughout the feeding process, the indicator arrow 318, fixedly connected to one side of the driven plate 310, slides synchronously on the measuring groove 319 on one side of the support column 301 as the driven plate 310 moves up and down. Operators can visually and clearly understand the advancement of the pusher plate 309 within the metering chamber body 306 by observing the position of the indicator arrow 318 on the measuring groove 319. This allows for precise control of the feeding amount, ensuring that each feeding achieves the expected accuracy and meets the stringent requirements of the adhesive reaction regarding the amount of material added.

[0050] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
