Description

Technical Field

[0001] The present invention relates to the technical field of material testing, and more specifically, to a water resistance detection auxiliary mechanism and preparation method for starch glue production. Background Technique

[0002] Starch glue is short for starch adhesive, which is a natural adhesive made with starch as the base material. Starch is a natural polymer produced by green plants through photosynthesis and belongs to plant glue. Starch glue has many advantages, such as rapid drying, firm adhesion, water and moisture resistance, anti-corrosion and anti-mildew, etc. Moreover, starch glue also has the characteristics of rich sources, low price, easy use, non-toxicity, etc., and has been widely used in the manufacture of waterproof paper and other aspects.

[0003] The starch glue modified and with waterproof performance can be used as a coating material to be coated on the surface of paper to form a dense waterproof layer. Therefore, in order to ensure the waterproof performance of waterproof paper, starch glue production enterprises supplying to waterproof paper production enterprises need to detect the water resistance of the prepared finished starch glue during the production and preparation process of starch glue.

[0004] Currently, there is no device for assisting in detecting the water resistance of the produced starch glue finished product during the production and preparation process of starch glue. When starch glue production enterprises detect the water resistance of starch glue, they often need to first take samples of the prepared starch glue in the production workshop, and then uniformly send the sampled starch glue to the laboratory for testing. And during the testing process, it is necessary to manually coat the starch glue on the surface of the paper, and detect the water resistance of the starch glue through the permeability of the coated paper. The above testing process, including sampling, transportation, laboratory preparation, testing, etc., has a relatively cumbersome process. And in order to ensure the objectivity of the data, it is often necessary to conduct multiple repeated tests, which takes a lot of time and effort and affects the testing efficiency. Moreover, in the above testing process, it is difficult to ensure the uniformity of coating by manually coating the starch glue on the surface of the paper, resulting in uneven distribution of the starch glue on the surface of the paper, thus affecting the accuracy of subsequent testing.

[0005] In view of this, we propose a water resistance detection auxiliary mechanism and preparation method for starch glue production. Summary of the Invention

[0039] The technical solution of this invention provides a production and preparation method of starch glue, including the following steps:

[0040] S1. Open the switch valve at the discharge port of the glue storage barrel, and continuously introduce the prepared starch glue into the container unit inside the coating structure through containers such as graduated cylinders;

[0041] S2. Open the stirring module in the container unit, and stir the starch glue before coating through two reciprocating stirring members;

[0042] S3. Discharge the starch glue from inside the container unit;

[0043] S4. Place the paper to be coated on the table surface of the detection table and fix it, slide the storage part so that the sliding storage part coats the starch glue on the paper surface;

[0044] S5. After the coating layer on the paper surface dries, fix the dried paper at the measuring structure;

[0045] S6. Slowly pour A1 liters of water onto the coated paper. After a time T, measure the amount of water A2 liters that drips through the paper and into the measuring structure. If A2 is within the preset range interval, the water resistance of the produced starch glue finished product meets the standard.

[0046] Beneficial effects: One or more of the technical solutions provided in the technical solution of the present invention have at least the following technical effects or advantages: 1. By continuously stirring the starch glue reciprocally through the stirring module, before the starch glue is coated, the components such as particles and additives in the starch glue are more evenly dispersed in the solvent, which helps to prevent agglomeration or precipitation inside the starch glue before coating. This helps to form a flat and uniform coating during the subsequent coating process, ensuring the surface quality and performance of the coated coating, and can effectively avoid the deviation of the test results caused by coating defects before the water resistance test.

[0047] 2. During the process of discharging the starch glue from the inside of the container unit, when the two stirring members in the stirring module reciprocate, they continuously drive the first diffusion mechanism and the second diffusion mechanism to push the discharged starch glue to both sides, realizing the redistribution process of the discharged starch glue. Thus, when subsequently coating the paper, it helps the starch glue to be more evenly distributed on the paper surface. Therefore, during subsequent repeated tests, the uniformity of each coating operation is guaranteed, which helps to obtain more stable and consistent test results in the repeated detection work of the starch glue and improves the reliability of the test results.

[0048] 3. During the discharging process, when the two stirring members in the stirring module move towards each other, under the action of the inclined guide rail part, the stirring members gradually change from the compressed state to the initial extended state and push the starch glue, so that during the discharging process, when the amount of the remaining starch glue inside is small, it further promotes the flow of the viscous starch glue material towards the discharge port in the container unit, reducing its residence time inside the equipment, which helps to accelerate the discharging speed of the starch glue and improve the detection efficiency.

[0049] 4. When the two stirring members in the stirring module move away from each other, that is, move towards the direction away from the discharge port, under the action of the inclined guide rail part, the stirring members gradually change from the extended state to the compressed state, reducing the direct interference of the movement on the flow of the starch glue towards the discharge port when the amount of the remaining starch glue inside is small, so that the starch glue can be discharged smoothly.

[0068] In the description of the present invention, it should be noted that unless otherwise clearly specified and limited, the terms "mounted", "connected", and "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0069] Refer to Figures 1 to 3 , Figure 8 , an auxiliary mechanism for water resistance detection in starch glue production according to an embodiment of the present invention includes a detection table 201. A coating structure and a measurement structure are respectively provided on the detection table 201. The coating structure includes a material storage part that can slide on the detection table 201. The material storage part includes a container unit, and a stirring module and a covering module are respectively provided on the container unit;

[0070] The stirring module includes a driving member and two elastically telescopic stirring members symmetrically arranged inside the container unit. The driving member includes an active convex tooth member connected to one of the stirring members, a gear connection member, a passive convex tooth member connected to the other stirring member, and a direct drive unit 209 connected to the active convex tooth member. The active convex tooth member includes a first diffusion mechanism, and the passive convex tooth member includes a second diffusion mechanism. When the direct drive unit 209 drives the active convex tooth member to move, the active convex tooth member drives the passive convex tooth member to move in a direction opposite to that of the active convex tooth member through the gear connection member;

[0071] An inclined guide rail part 218 in an inclined state is provided at the positions corresponding to the two stirring members inside the container unit, and the two stirring members slide on the corresponding inclined guide rail parts 218 respectively. When the driving member drives the two stirring members to move away from each other, the inclined guide rail part 218 drives the corresponding stirring member to gradually change from the initial extended state to the compressed state.

[0072] By continuously stirring the starch glue reciprocally through the stirring module, the components such as particles and additives in the starch glue material are more evenly dispersed in the solvent, which helps to prevent agglomeration or precipitation inside the starch glue before coating. Subsequently, during the process of discharging the starch glue from the inside of the container unit, the reciprocating stirring module also continuously pushes the discharged starch glue to both sides, so as to help form a more uniform coating on the paper surface during subsequent paper coating. Then, the sliding storage part is slid, so that the sliding storage part coats the starch glue on the paper surface. After the coating layer on the paper surface is dried, the dried paper is fixed at the measuring structure for detection. In this way, it is convenient for the inspectors to conduct on-site auxiliary detection on the produced finished products in the starch glue production factory. Compared with the traditional detection method of sampling and sending for inspection, this device not only improves the detection efficiency, but also helps to improve the reliability of the detection results.

[0073] Refer to Figures 1 to 3 、 Figure 5 、 Figure 7 and Figure 8 In this regard, an embodiment of the present invention provides an auxiliary mechanism for water resistance detection in starch glue production. The container unit includes a material box 203 and a linear module 207. A top cover is hermetically covered at the top opening of the material box 203;

[0074] The bottom of the material box 203 is fixedly communicated with a discharge port, and a switch valve 208 is provided on the discharge port;

[0075] A transparent observation window is also provided on the material box 203;

[0076] The material box 203 is also connected with a support sliding frame 205 that slides on the detection table 201;

[0077] Two sliding material slopes are symmetrically provided on the inner bottom wall of the cavity of the material box 203, and the discharge port is located between the two sliding material slopes. The inclined chute helps the starch glue to slide towards the discharge port, facilitating discharging;

[0078] The linear module 207 is a linear motor connected to the middle table top of the detection table 201, and the support sliding frame 205 is connected to the moving seat in the linear motor.

[0079] Refer to Figure 11 and Figure 12 In this regard, an embodiment of the present invention provides an auxiliary mechanism for water resistance detection in starch glue production. The inclined guide rail part 218 is an inclined guide bar in an inclined state;

[0080] Two diagonal guide rail parts 218 are respectively connected to the front and rear sides of the inner cavity of the cartridge 203.

[0081] Referring to Figures 8 to 13 , an embodiment of the present invention provides an auxiliary mechanism for detecting water resistance in the production of starch glue. The stirring member includes a hollow vertical seat 223, and a retractable sliding seat 222 slides up and down in the inner cavity of the hollow vertical seat 223;

[0082] A spring is provided above the retractable sliding seat 222, and one end of the spring is connected to the retractable sliding seat 222, and the other end is connected to the top end of the inner cavity of the hollow vertical seat 223;

[0083] A plurality of vertical connecting rods 221 are uniformly connected to the bottom of the retractable sliding seat 222, and the bottom ends of the plurality of vertical connecting rods 221 all slide through the bottom end of the hollow vertical seat 223 and are commonly connected to a stirring seat 220;

[0084] An obliquely arranged chute adapted to the diagonal guide bar 218 is formed in the side wall of the stirring seat 220;

[0085] The two diagonal guide bars 218 respectively extend into the two obliquely arranged chutes;

[0086] A connecting cross bar 217 is connected to the side wall of the hollow vertical seat 223.

[0087] By continuously stirring the starch glue reciprocally through the stirring module, the components such as particles and additives in the starch glue material are more evenly dispersed in the solvent, which helps to prevent agglomeration or precipitation inside the starch glue before coating. This helps to form a flat and uniform coating during the subsequent coating process, ensuring the surface quality and performance of the coated coating, and can effectively avoid the deviation of the detection result caused by coating defects before the water resistance detection.

[0088] During the discharging process, when the two stirring members in the stirring module move towards each other, under the action of the diagonal guide rail part 218, the stirring member gradually changes from the compressed state to the initial extended state and pushes the starch glue, so that during the discharging process, when the amount of remaining starch glue in 203 is small, it further promotes the flow of the viscous starch glue material towards the discharge port in the container unit, reduces its residence time inside the equipment, and thus helps to accelerate the discharging speed of the starch glue and improve the detection efficiency.

[0089] When the two stirring members in the stirring module move away from each other, that is, move away from the discharge port, under the action of the diagonal guide rail part 218, the stirring member gradually changes from the extended state to the compressed state, reducing the direct interference of the movement of 220 on the flow of the starch glue towards the discharge port when the amount of remaining starch glue in 203 is small, so that the starch glue can be discharged smoothly.

[0090] Referring to Figures 5 to 8 , an embodiment of the present invention provides an auxiliary mechanism for detecting water resistance in the production of starch glue. The active convex tooth member includes an active L-shaped horizontal frame 212, which includes a first horizontal section and a first vertical section. The first vertical section slides horizontally on the side wall of the material box 203;

[0091] A row of convex teeth is evenly arranged on the first vertical section;

[0092] The passive convex tooth member includes a passive L-shaped horizontal frame 206, which includes a second horizontal section and a second vertical section;

[0093] A row of convex teeth is also evenly arranged on the second vertical section;

[0094] The end of the connecting cross bar 217 in one of the stirring members passes through the side wall of the material box 203 in a sealed manner and is connected to the first horizontal section in the active convex tooth member, and the end of the connecting cross bar 217 in the other stirring member passes through the side wall of the material box 203 in a sealed manner and is connected to the second horizontal section in the passive convex tooth member;

[0095] The first diffusion mechanism includes a first traction arm 214 connected to the first vertical section, and a side push seat 216 is connected to the first traction arm 214;

[0096] The second diffusion mechanism includes a second traction arm 215 connected to the second vertical section, and a side push seat 216 is also connected to the second traction arm 215;

[0097] The two side push seats 216 are arranged staggeredly, and both of the two side push seats 216 are located below the discharge port in the container unit. When the driving member is in the initial state, the discharge port is located between the two side push seats 216;

[0098] Referring to Figure 3 , Figure 4 , the direct drive unit 209 is a cylinder, and the fixed end of the cylinder is connected to the side wall of the material box 203, and the free end of the cylinder is connected to the first horizontal section in the active convex tooth member.

[0099] During the process of discharging the starch glue from the inside of the container unit, when the two stirring members in the stirring module reciprocate, they continuously drive the first diffusion mechanism and the second diffusion mechanism to push the discharged starch glue to both sides, realizing the redistribution process of the discharged starch glue. Thus, when coating the paper subsequently, it helps the starch glue to be more evenly distributed on the paper surface. Therefore, during subsequent repeated detections, the uniformity of each coating operation is ensured, which helps to obtain more stable and consistent detection results in the repeated detection work of starch glue and improves the reliability of the detection results.

[0100] Referring toFigure 5 and Figure 6 In an embodiment of the present invention, a water resistance detection auxiliary mechanism for starch glue production is provided. The gear connection member includes a gear bracket connected to the side wall of the material box 203, and the second vertical section in the passive convex tooth member slides horizontally inside the gear bracket;

[0101] A middle gear 213 is rotatably connected inside the gear bracket between the first vertical section and the second vertical section, and the middle gear 213 meshes with the convex teeth on the first vertical section and the second vertical section respectively.

[0102] When the direct drive unit 209 drives the active convex tooth member to move, and the active convex tooth member drives the stirring member connected thereto to move, the active convex tooth member drives the middle gear 213 in the gear connection member to rotate through the convex teeth on its second vertical section. The rotating middle gear 213 synchronously drives the passive convex tooth member to move, so that the passive convex tooth member drives the stirring member connected thereto to move. Thus, during the reciprocating telescoping process of the direct drive unit 209, the two stirring members located in the container unit can move towards or away from each other.

[0103] Refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 5 In an embodiment of the present invention, a water resistance detection auxiliary mechanism for starch glue production is provided. The covering module includes a connecting frame 210. One end of the connecting frame 210 is connected with a glue scraping plate 211, and the other end of the connecting frame 210 is connected to the side wall of the material box 203;

[0104] The number of the covering modules is two, and they are respectively connected to the front and rear sides of the container unit. Two side pushing seats 216 are arranged between the two glue scraping plates 211.

[0105] After discharging the starch glue from the inside of the container unit, close the switch valve 208 on the discharge port in the container unit. Then, after turning off the direct drive unit 209 in the stirring module, turn on the linear module 207 in the container unit. During the process of driving the container unit to move slowly by the linear module 207, the covering module connected to the container unit scrapes the discharged starch glue on the paper surface, thereby completing the automatic coating work in the detection work.

[0106] Refer to Figure 1 and Figure 2 In an embodiment of the present invention, a water resistance detection auxiliary mechanism for starch glue production is provided. The measuring structure includes a transparent graduated cylinder 202 and a hole channel arranged on the tabletop of the detection table 201;

[0107] The transparent graduated cylinder 202 is detachably connected to the bottom of the middle tabletop of the detection table 201. The detachable connection method includes threaded connection or snap connection, and the top opening of the transparent graduated cylinder 202 faces the pore channel.

[0108] After the coating layer on the paper surface is dried, the dried paper is fixed to the measurement structure on the detection table 201 by tools such as thumbtacks, so that the paper is located above the pore channel in the measurement structure.

[0109] Next, slowly pour A1 liters of water onto the coated paper. After a time T, measure the amount of water A2 liters that drips through the coated paper into the transparent graduated cylinder 202 in the measurement structure. If A2 is within the preset range interval, it indicates that the waterproof paper made of this starch glue has qualified permeability. Furthermore, it indicates that the water resistance of the produced starch glue finished product meets the standard.

[0110] The embodiment of the present invention provides a production preparation method of starch glue, including the following steps.
