Description

Technical Field

[0001] The present invention relates to the field of coating devices, and more particularly to a coating machine feeding device and a use method thereof. Background Art

[0002] Coating machines are mainly used for surface coating production of films, papers, etc. This machine coats the rolled substrate with a layer of glue, paint or ink with specific functions, and then rewinds it after drying. The paint and diluent used by the coating machine are usually thoroughly stirred in the storage tank to ensure the homogeneity and stability of the paint, thereby ensuring the quality and efficiency of the coating process.

[0003] The Chinese patent application with the publication number CN114887844A discloses a coating machine feeding device, which ensures that the return speed of the movable plate is slow each time and the discharge amount of the coating liquid each time through the design of the air hole and the spring on the cylinder.

[0004] The above patent still has the following deficiencies:

[0005] In the process, a large amount of raw materials will be stored in the pipeline;

[0006] The raw materials are transported to the coating machine through the pipeline system. In the process of transporting the raw materials through the pipeline, changing the discharge amount through the movable plate will cause part of the raw materials to be in a static state. In the static state, stratification will occur, especially when the pipeline is long, curved or the flow rate changes, the stratification phenomenon will be aggravated to affect the normal operation of the coating machine and the quality of the final product.

[0007] To this end, a coating machine feeding device and a use method thereof are proposed. Summary of the invention

[0008] In view of the problems existing in the prior art, the object of the present invention is to provide a coating machine feeding device and a method of using the same, which can shorten the time that the raw material stays in the feed pipe, thereby reducing the probability of raw material stratification.

[0009] To solve the above problems, the present invention adopts the following technical solutions.

[0010] A coating machine feeding device includes a storage tank and a feeding pipe, wherein the coating and the diluent are poured into the storage tank, and then stirred evenly, and the stirred raw materials are transported to the coating machine through the feeding pipe;

[0011] A baffle is movably inserted on the top wall of the feed pipe. The flow rate of the feed pipe can be changed by inserting the baffle into the feed pipe.

[0012] A mounting sleeve is vertically fixedly installed in the conveying pipe, an upper pipe is horizontally rotated and inserted on the side wall of the mounting sleeve, and discharge ports are evenly opened on the side wall of the upper pipe;

[0013] A rotating shaft is vertically rotatably installed in the conveying pipe, and the top end extends into the mounting sleeve. A lower tube is horizontally movablely sleeved on the rotating shaft. Feed ports are evenly provided on the side walls of the lower tube. Active magnets and driven magnets are fixedly installed on the baffle and the lower tube, respectively, and the active magnets and driven magnets attract each other. Therefore, during the movement of the baffle, the lower tube can be driven to move along with the baffle through the attraction between the active magnet and the driven magnet. Therefore, the baffle can drive the lower tube to move, and a transfer mechanism for transferring the raw materials in the lower tube to the upper tube is provided in the conveying pipe. The bottom layer of raw materials in the space above the bottom wall of the baffle can be transferred to the mounting sleeve through the transfer mechanism, and then flow along the mounting sleeve to the upper tube, and finally be evenly discharged through the discharge port on the side wall of the upper tube.

[0014] Stirring rods are evenly installed on the side walls of the upper tube, and a driving mechanism for driving the upper tube to rotate is arranged in the mounting sleeve; the upper tube and the stirring rods are driven to rotate by the driving mechanism, so that the bottom layer of raw materials and the top layer of raw materials discharged from the discharge port can be stirred, and the raw materials stored between the bottom wall of the baffle and the top wall of the feed pipe can be stirred evenly; and in the process of the upper tube rotating, the raw materials discharged from the discharge port and the top layer of raw materials in the feed pipe can be evenly mixed, thereby improving the efficiency of stirring and mixing and improving the stirring effect;

[0015] A mounting frame is installed in the feed pipe, and a disc is rotatably mounted on the mounting frame. The disc is provided with holes, and the raw materials in the feed pipe can pass through the holes. A rotating mechanism for driving the disc to rotate is provided in the feed pipe. During the process of the rotating mechanism driving the disc to rotate, the position of the hole changes at any time, so that the raw materials at various heights in the feed pipe can pass through the holes, thereby shortening the time that the raw materials stay in the feed pipe, and being able to transfer the raw materials in time, which prevents the raw materials from being stratified. The raw materials that pass through the holes fall downwards and flow out through the space between the bottom wall of the baffle and the bottom wall of the feed pipe.

[0016] Furthermore, the transfer mechanism includes a catheter fixedly inserted on the top wall of the lower tube, the catheter is a telescopic tube, so the catheter can be extended, and when the catheter is in a negative pressure state, the catheter can still maintain its original shape, the catheter extends to the bottom wall of the mounting sleeve, the upper tube is connected to the lower tube through the catheter, the part of the rotating shaft located in the mounting sleeve is fixedly sleeved with a reciprocating screw, the bottom end of the rotating shaft extends to the bottom wall of the feed pipe, a wind cup is evenly circumferentially installed at the bottom of the side wall of the rotating shaft, a slider is threadedly installed on the reciprocating screw, an elastic airbag is installed between the slider and the bottom wall of the mounting sleeve, a first one-way valve is installed on the output end of the elastic airbag, the first one-way valve is an output valve, and a second one-way valve connected with the input end of the elastic airbag is installed on the input end; because the baffle is arranged along the vertical It is plugged and pulled out in the direction of the feed pipe, so the raw material in the feed pipe always passes through the space between the baffle and the bottom wall inside the feed pipe, that is, the raw material flowing along the feed pipe will impact the wind cup, and the wind cup subjected to the impact force drives the rotating shaft to rotate, thereby driving the reciprocating screw to rotate. During the rotation of the reciprocating screw, the slider drives the elastic airbag to intermittently extend and recover. When the elastic airbag extends, the elastic airbag absorbs raw material from the lower tube through the second one-way valve and the conduit. When the elastic airbag is squeezed, the raw material in the elastic airbag is discharged into the mounting sleeve through the first one-way valve, and the raw material in the mounting sleeve will enter the upper tube under the action of pressure, thereby realizing the effect of transferring the bottom layer of raw material in the space between the bottom wall of the baffle and the top wall inside the feed pipe to the top layer.

[0017] Furthermore, the driving mechanism includes a driving gear fixedly mounted on the rotating shaft, a bracket fixedly mounted on the inner wall of the upper tube, a driven gear fixedly mounted on the bracket, and the driving gear meshes with the driven gear. Therefore, during the rotation of the rotating shaft, the driven gear can be driven to rotate by the driving gear, and then the upper tube can be driven to rotate by the bracket, thereby achieving the function of driving the upper tube to rotate.

[0018] Furthermore, the ratio of the inner diameter of the feed pipe to the diameter of the disc is 1.1-1.3, so there is a gap between the disc and the inner wall of the feed pipe, and part of the raw material passes through the gap between the bottom wall of the disc and the bottom wall of the feed pipe and impacts the wind cup, which ensures that the wind cup can drive the rotating shaft to rotate.

[0019] Furthermore, the rotating mechanism includes teeth grooves evenly arranged on the side wall of the disc, a connecting rod penetrating the mounting sleeve is fixedly mounted on the bracket, the connecting rod is rotatably inserted on the side wall of the mounting sleeve, and a gear ring meshing with the teeth groove is fixedly mounted on the end of the connecting rod; therefore, during the rotation of the bracket, the gear ring can be driven to rotate by the connecting rod, and then the disc is driven to rotate by the mutually meshing gear ring and teeth groove, thereby playing the role of driving the disc to rotate.

[0020] Furthermore, the stirring rod includes a sleeve and an inner rod, the sleeve is vertically mounted on the surface of the upper tube, the inner rod is movably inserted on the sleeve, and an elastic member is installed between the sleeve and the inner rod. When the inner rod is out of contact with the feeding tube, the elastic member pushes the inner rod out of the sleeve, at which time the contact area between the stirring rod and the raw material is increased, and the stirring effect is improved; when the upper tube drives the sleeve to rotate, the inner wall of the feeding tube exerts resistance on the inner rod, and at this time the inner rod retracts into the sleeve, ensuring that the upper tube can rotate freely.

[0021] Furthermore, a cavity is opened on the elastic member, and a pressure tube extending into the feed pipe is inserted into the bottom wall of the cavity; when the inner rod is obstructed by the inner wall of the feed pipe and retracts into the sleeve, the cavity is in a high-pressure state, and at this time, the upper tube connected to the cavity through the pressure tube is also in a high-pressure state, so the diffusion range of the raw materials discharged from the discharge port will be expanded, thereby improving the mixing effect during the stirring process of the stirring rod.

[0022] Furthermore, a pressure relief valve is installed at the end of the pressurizing pipe, and a third one-way valve connected to the feed pipe is embedded on the side wall of the cavity; the cavity draws raw materials from the feed pipe through the pressure relief valve, and when the elastic member is squeezed, the cavity discharges the raw materials through the pressure relief valve, so the cavity only pressurizes the inside of the upper pipe and does not cause the pressure in the upper pipe to decrease, thereby ensuring that the raw materials discharged from the discharge port can diffuse normally.

[0023] The present invention also provides a method for using the above-mentioned coating machine feeding device, comprising the following steps:

[0024] S1. Pour the coating and the thinner into a storage tank, and stir the coating and the thinner evenly to form a raw material;

[0025] S2, adjusting the depth of the baffle plate inserted into the feed pipe, thereby controlling the flow of the raw material passing through the bottom wall of the baffle plate and the inner bottom wall of the feed pipe;

[0026] S3. The raw material flowing in the feeding pipe impacts the wind cup, which drives the rotating shaft to rotate, and then drives the reciprocating screw to rotate, thereby driving the elastic airbag to intermittently expand and contract;

[0027] S4. When the elastic airbag is stretched, the elastic airbag absorbs the raw material from the lower tube through the catheter;

[0028] S5. When the elastic airbag contracts, the raw materials in the elastic airbag are discharged into the upper tube through the mounting sleeve, and at the same time, the driving gear on the rotating shaft drives the driven gear to rotate. At this time, the upper tube rotates synchronously and drives the stirring rod to rotate. The stirring rod stirs the raw materials discharged from the discharge port and the initial top layer raw materials to mix the raw materials evenly.

[0029] S6. The disc is driven to rotate through the connecting rod and the gear ring, so that the raw materials at various heights in the conveying pipe can be discharged regularly.

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] (1) This solution can transfer the bottom layer of raw materials in the space between the bottom wall of the baffle and the top wall of the feed pipe to the top layer by setting the upper tube, the lower tube and the transfer mechanism, so that the layered raw materials can be mixed evenly again. At the same time, the upper tube can be driven to rotate by the driving mechanism, which can drive the stirring rod to stir the mixed raw materials, thereby improving the mixing effect of the raw materials;

[0032] (2) This solution provides a disc, a tooth groove, and a gear ring, so that the holes can rotate together with the disc, so that the raw materials at all heights in the feed pipe can be discharged regularly, shortening the time the raw materials stay in the feed pipe and reducing the probability of raw material stratification;

[0033] (3) This solution provides a sleeve, an inner rod and an elastic member. When the inner rod is out of contact with the feed pipe, the elastic member pushes the inner rod out of the sleeve. At this time, the contact area between the stirring rod and the raw material is increased, thereby improving the stirring effect.

[0034] (4) In this scheme, by providing an elastic member and a cavity, when the inner rod is obstructed by the inner wall of the feed pipe and retracts into the sleeve, the cavity is in a high-pressure state. At this time, the upper tube connected to the cavity through the pressurized tube is also in a high-pressure state. Therefore, the diffusion range of the raw materials discharged from the discharge port will be expanded, thereby improving the mixing effect during the stirring process of the stirring rod.

DETAILED DESCRIPTION

[0044] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0045] Embodiment 1:

[0046] See also Figures 1 to 7 , a coating machine feeding device, comprising a storage tank 1 and a feeding pipe 2, pouring the coating and the diluent into the storage tank 1, and then stirring them evenly, and conveying the stirred raw materials to the coating machine through the feeding pipe 2;

[0047] A baffle plate 3 is movably inserted on the top wall of the feed pipe 2. By inserting the baffle plate 3 into the feed pipe 2, the flow rate of the feed pipe 2 can be changed.

[0048] A mounting sleeve 4 is vertically fixedly installed in the conveying pipe 2, an upper pipe 5 is horizontally rotated and inserted on the side wall of the mounting sleeve 4, and discharge ports are evenly opened on the side wall of the upper pipe 5;

[0049] A rotating shaft 6 is vertically rotatably installed in the conveying pipe 2, and the top end extends to the mounting sleeve 4. A lower tube 7 is horizontally movable sleeved on the rotating shaft 6. Feed ports are evenly opened on the side walls of the lower tube 7. Active magnets 8 and driven magnets 9 are fixedly installed on the baffle 3 and the lower tube 7, respectively, and the active magnets 8 and the driven magnets 9 attract each other. Therefore, during the movement of the baffle 3, the lower tube 7 can be driven to move along with the baffle 3 by the attraction between the active magnet 8 and the driven magnet 9. Therefore, the baffle 3 can drive the lower tube 7 to move, and a transfer mechanism for transferring the raw materials in the lower tube 7 to the upper tube 5 is provided in the conveying pipe 2; the bottom layer of raw materials in the space above the bottom wall of the baffle 3 can be transferred to the mounting sleeve 4 through the transfer mechanism, and then flow along the mounting sleeve 4 to the upper tube 5, and finally be evenly discharged through the discharge port on the side wall of the upper tube 5;

[0050] Stirring rods 10 are evenly installed on the side walls of the upper tube 5, and a driving mechanism for driving the upper tube 5 to rotate is provided in the mounting sleeve 4; the upper tube 5 and the stirring rods 10 are driven to rotate by the driving mechanism, so that the bottom layer of raw materials and the top layer of raw materials discharged from the discharge port can be stirred, and the raw materials stored between the bottom wall of the baffle 3 and the top wall of the feed pipe 2 can be stirred evenly; and during the rotation of the upper tube 5, the raw materials discharged from the discharge port can be evenly mixed with the top layer of raw materials in the feed pipe 2, thereby improving the efficiency of stirring and mixing and improving the stirring effect;

[0051] A mounting frame 11 is installed in the feed pipe 2, and a disc 12 is rotatably mounted on the mounting frame 11. The disc 12 is provided with a hole 13, and the raw materials in the feed pipe 2 can pass through the hole 13. A rotating mechanism for driving the disc 12 to rotate is provided in the feed pipe 2. During the process of the rotating mechanism driving the disc 12 to rotate, the position of the hole 13 can change at any time, so that the raw materials at various heights in the feed pipe 2 can pass through the hole 13, thereby shortening the time that the raw materials stay in the feed pipe 2, and being able to transfer the raw materials in time, which prevents the raw materials from being stratified, and the raw materials passing through the hole 13 fall downwards and flow out through the space between the bottom wall of the baffle 3 and the bottom wall of the feed pipe 2.

[0052] like Figure 2As shown, the transfer mechanism includes a catheter 14 fixedly inserted on the top wall of the lower tube 7. The catheter 14 is a telescopic tube, so the catheter 14 can be extended, and when the catheter 14 is in a negative pressure state, the catheter 14 can still maintain its original shape. The catheter 14 extends to the inner bottom wall of the mounting sleeve 4, and the upper tube 5 is connected with the lower tube 7 through the catheter 14. The part of the rotating shaft 6 located in the mounting sleeve 4 is fixedly sleeved with a reciprocating screw rod 15, and the bottom end of the rotating shaft 6 extends to the inner bottom wall of the feed pipe 2. A wind cup 16 is evenly installed on the bottom circumference of the side wall of the rotating shaft 6. A slider is threadedly installed on the reciprocating screw rod 15, and an elastic air bag 28 is installed between the slider and the bottom wall of the mounting sleeve 4. A first one-way valve 29 is installed on the output end of the elastic air bag 28. The first one-way valve 29 is an output valve, and a second one-way valve 30 connected with the input end of the catheter 14 is installed on the input end of the elastic air bag 28; because the baffle 3 is along It is plugged and pulled out in a direction perpendicular to the feed pipe 2, so the raw material in the feed pipe 2 always passes through the space between the baffle 3 and the inner bottom wall of the feed pipe 2, that is, the raw material flowing along the feed pipe 2 will impact the wind cup 16, and the wind cup 16 subjected to the impact force drives the rotating shaft 6 to rotate, thereby driving the reciprocating screw 15 to rotate. During the rotation of the reciprocating screw 15, the slider drives the elastic airbag 28 to extend and recover intermittently. When the elastic airbag 28 extends, the elastic airbag 28 absorbs the raw material from the lower tube 7 through the second one-way valve 30 and the conduit 14. When the elastic airbag 28 is squeezed, the raw material in the elastic airbag 28 is discharged into the mounting sleeve 4 through the first one-way valve 29, and the raw material in the mounting sleeve 4 will enter the upper tube 5 under the action of pressure, thereby realizing the effect of transferring the bottom layer of raw material in the space between the bottom wall of the baffle 3 and the inner top wall of the feed pipe 2 to the top layer.

[0053] like Figure 3 , Figure 5 As shown, the driving mechanism includes a driving gear 17 fixedly mounted on the rotating shaft 6, a bracket 18 fixedly mounted on the inner wall of the upper tube 5, a driven gear 19 fixedly mounted on the bracket 18, and the driving gear 17 is meshed with the driven gear 19. Therefore, during the rotation of the rotating shaft 6, the driven gear 19 can be driven to rotate by the driving gear 17, and then the upper tube 5 can be driven to rotate by the bracket 18, thereby achieving the function of driving the upper tube 5 to rotate.

[0054] like Figure 2 As shown, the ratio of the inner diameter of the feed pipe 2 to the diameter of the disc 12 is 1.1-1.3, so there is a gap between the disc 12 and the inner wall of the feed pipe 2, and part of the raw material passes through the gap between the bottom wall of the disc 12 and the inner bottom wall of the feed pipe 2 and impacts the wind cup 16, which ensures that the wind cup 16 can drive the rotating shaft 6 to rotate.

[0055] like Figure 5As shown, the rotating mechanism includes tooth grooves 20 evenly arranged on the side wall of the disc 12, a connecting rod 21 penetrating the mounting sleeve 4 is fixedly mounted on the bracket 18, the connecting rod 21 is rotatably inserted on the side wall of the mounting sleeve 4, and a gear ring 22 meshing with the tooth groove 20 is fixedly mounted on the end of the connecting rod 21; therefore, during the rotation of the bracket 18, the gear ring 22 can be driven to rotate by the connecting rod 21, and then the disc 12 is driven to rotate by the mutually meshing gear ring 22 and the tooth groove 20, that is, the disc 12 is driven to rotate.

[0056] like Figure 4 As shown, the stirring rod 10 includes a sleeve 101 and an inner rod 102, the sleeve 101 is vertically mounted on the surface of the upper tube 5, the inner rod 102 is movably inserted on the sleeve 101, and an elastic member 23 is installed between the sleeve 101 and the inner rod 102. When the inner rod 102 is out of contact with the feeding pipe 2, the elastic member 23 pushes the inner rod 102 to extend out of the sleeve 101, at which time the contact area between the stirring rod 10 and the raw material is increased, and the stirring effect is improved; in the process of the upper tube 5 driving the sleeve 101 to rotate, the inner wall of the feeding pipe 2 applies resistance to the inner rod 102, and at this time the inner rod 102 retracts into the sleeve 101, ensuring that the upper tube 5 can rotate freely.

[0057] like Figure 4 As shown, a cavity 24 is opened on the elastic member 23, and a pressurizing tube 25 extending into the feed pipe 2 is inserted on the bottom wall of the cavity 24; when the inner rod 102 is obstructed by the inner wall of the feed pipe 2 and retracts into the sleeve 101, the cavity 24 is in a high-pressure state, and at this time, the upper tube 5 connected to the cavity 24 through the pressurizing tube 25 is also in a high-pressure state, so the diffusion range of the raw materials discharged from the discharge port will be expanded, thereby improving the mixing effect during the stirring process of the stirring rod 10.

[0058] like Figure 4 As shown, a pressure relief valve 27 is installed at the end of the pressurizing pipe 25, and a third one-way valve 26 connected to the feed pipe 2 is embedded on the side wall of the cavity 24; the cavity 24 draws raw materials from the feed pipe 2 through the pressure relief valve 27, and when the elastic member 23 is squeezed, the cavity 24 discharges the raw materials through the pressure relief valve 27. Therefore, the cavity 24 only pressurizes the inside of the upper tube 5 without causing the pressure in the upper tube 5 to decrease, thereby ensuring that the raw materials discharged from the discharge port can diffuse normally.

[0059] The present invention also provides a method for using the above-mentioned coating machine feeding device, comprising the following steps:

[0060] S1, pouring the coating and the diluent into the storage tank 1, and stirring the coating and the diluent evenly to form a raw material;

[0061] S2, adjusting the depth of the baffle plate 3 inserted into the feed pipe 2, thereby controlling the flow of the raw material passing through the bottom wall of the baffle plate 3 and the inner bottom wall of the feed pipe 2;

[0062] S3, the raw material flowing in the feeding pipe 2 impacts the wind cup 16, the wind cup 16 drives the rotating shaft 6 to rotate, and then drives the reciprocating screw rod 15 to rotate, thereby driving the elastic airbag 28 to intermittently expand and contract;

[0063] S4, when the elastic airbag 28 is stretched, the elastic airbag 28 absorbs the raw material from the lower tube 7 through the conduit 14;

[0064] S5, when the elastic airbag 28 contracts, the raw materials in the elastic airbag 28 are discharged into the upper tube 5 through the mounting sleeve 4, and at the same time, the driving gear 17 on the rotating shaft 6 drives the driven gear 19 to rotate, and at this time, the upper tube 5 rotates synchronously and drives the stirring rod 10 to rotate, and the raw materials discharged from the discharge port and the initial top layer raw materials are stirred by the stirring rod 10 to stir the raw materials evenly;

[0065] S6. The disc 12 is driven to rotate by the linkage rod 21 and the gear ring 22, so that the raw materials at various heights in the conveying pipe 2 can be discharged at a regular time.

[0066] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
