Description

Technical Field

[0001] The invention relates to the technical field of hot melt adhesives, and in particular to a colloid defoaming device and a colloid defoaming method. Background Art

[0002] Currently, in the production process of hot melt adhesive, stirring and defoaming agents are mostly used in combination to reduce bubbles in the hot melt adhesive, but the defoaming ability has an upper limit. During the use of hot melt adhesive, bubbles inside the hot melt adhesive during the flow and melting process will also bring certain risks to the hot melt adhesive coating, affecting the stability of subsequent glue output. Summary of the invention

[0003] Based on this, it is necessary to provide a colloid defoaming device and a colloid defoaming method to address the problem of poor defoaming effect of existing hot melt adhesive devices.

[0004] A colloid defoaming device includes a feeding mechanism and a defoaming mechanism. The feeding mechanism includes a feeding bin. The defoaming mechanism includes a receiving bin, a stirring component and a pressure regulating component. The pressure regulating component is connected to the receiving bin and is used to adjust the air pressure in the receiving bin. The stirring component is arranged in the receiving bin, and the receiving bin is connected to the feeding bin. The receiving bin is connected to the feeding bin. The receiving bin is used to receive the colloid output from the feeding bin. After the pressure regulating component adjusts the air pressure in the receiving bin to a preset pressure, the stirring component stirs the colloid to eliminate the bubbles in the colloid. In the above-mentioned colloid defoaming device, the colloid is output from the feeding bin to the feeding bin. When the pressure regulating component adjusts the air pressure in the receiving bin to a preset pressure, the colloid can be initially defoamed. Then, the stirring component is used to stir the colloid to eliminate the bubbles in the colloid for a second time. No defoaming agent is needed. A better colloid defoaming effect can be achieved, which reduces the defoaming cost and improves the colloid discharge stability.

[0005] In some embodiments, the pressure regulating assembly includes a pressure regulating driving member and a connecting pipe, the pressure regulating driving member is located outside the material receiving bin, and the pressure regulating driving member is connected to the material receiving bin through the connecting pipe; the pressure regulating driving member can generate negative pressure to adjust the air pressure in the material receiving bin. In this way, the air pressure in the material receiving bin can be adjusted by the pressure regulating driving member, which is convenient to operate and has a reasonable structure.

[0006] In some embodiments, the pressure regulating assembly further includes a pressure detecting member, which is disposed in the receiving bin and used to detect the air pressure in the receiving bin; the colloid defoaming device further includes a controller electrically connected to the pressure detecting member and the pressure regulating driving member, and the controller controls the operating state of the pressure regulating driving member according to the air pressure detection value of the pressure detecting member. In this way, the operating state of the pressure regulating driving member can be controlled according to the air pressure detection value of the pressure detecting member, so that when the air pressure in the receiving bin reaches a preset air pressure value, the air pressure regulation in the receiving bin is stopped in time, so that the colloid can be initially defoamed.

[0007] In some embodiments, the pressure regulating assembly further includes a pressure regulating control valve, a vacuum interface connected to the connecting pipe is provided on the side wall of the receiving bin, and the pressure regulating control valve is provided at the vacuum interface and is used to open and close the vacuum interface. In this way, when the air pressure of the receiving bin needs to be adjusted, the vacuum interface can be automatically opened, thereby improving the degree of automation of the device.

[0008] In some embodiments, the material discharge bin has a feed inlet and a material discharge inlet arranged relatively along a first direction, the material receiving bin has a material receiving inlet and a material discharge inlet arranged relatively along the first direction, the material receiving inlet is connected to the material discharge inlet, the stirring assembly is located between the material receiving inlet and the material discharge inlet, and the first direction is the axial direction of the material receiving bin. In this way, the dead angle of loading and unloading can be reduced, so that the colloid in the material discharge bin can be smoothly input into the material receiving bin, which is conducive to improving the defoaming efficiency of the colloid.

[0009] In some embodiments, the stirring assembly includes a stirring drive and a stirring structure, the stirring structure extends along a first direction, and the stirring drive is connected to the stirring structure; under the driving of the stirring drive, the stirring structure can rotate around the central axis of the receiving bin. In this way, the stirring drive can be used to drive the stirring structure to rotate, so that the colloid in the receiving bin is stirred and defoamed, and the structural design is reasonable and easy to operate.

[0010] In some embodiments, the stirring structure includes a connecting shaft and at least two blades, each blade is spaced and distributed along the first direction on the outer periphery of the connecting shaft, and the stirring driving member is fixedly connected to one end of the connecting shaft near the discharge port. In this way, bubbles in the discharged colloid can be eliminated by stirring, which is fast and convenient; the stirring driving member and the flow guide member are respectively arranged at both ends of the connecting shaft, making the device structure more compact and conducive to improving space utilization.

[0011] In some embodiments, the stirring structure further includes a flow guide, which is arranged at one end of the connecting shaft close to the material receiving port; the outer diameter of the flow guide gradually increases in the direction from the material receiving port to the material discharging port. In this way, after the colloid is input into the material receiving port, it can be decelerated under the action of the flow guide and flow smoothly into the material receiving bin, which is beneficial to the transportation and defoaming of the colloid.

[0012] In some embodiments, the guide member is configured as a conical structure, so that the guide member can play a good guiding role, so that the colloid can flow into the receiving bin quickly under the guidance of the guide member.

[0013] In some embodiments, the stirring structure further includes a first filter screen, which is arranged around the outer periphery of the connecting shaft; in the first direction, each blade and the guide member have a spacing space, and the first filter screen is located in the spacing space. In this way, before the colloid is output from the receiving bin, impurities can be filtered through the first filter screen before stirring, and then output, which greatly reduces impurities and bubbles in the colloid.

[0014] In some embodiments, the feeding mechanism includes a heating component, which is arranged between the feeding port and the feeding port and is used to heat and melt the rubber block. In this way, the solid rubber block can be heated and melted into a liquid colloid before being output, which is beneficial to the colloid heat preservation to eliminate bubbles.

[0015] In some embodiments, the heating assembly includes at least two heating tubes, each of which is staggered and distributed on opposite sides of the length direction of the lower material bin. In this way, each of the heating tubes is staggered and distributed on opposite sides of the length direction of the lower material bin, thereby extending the flow path of the colloid, so that the rubber block can be completely melted into the colloid.

[0016] In some embodiments, the feeding mechanism further includes a second filter screen, which is arranged downstream of the heating component. Thus, before the colloid is output from the feeding bin, impurities can be filtered out through the second filter screen before output, thereby significantly reducing impurities in the colloid.

[0017] In some embodiments, the material discharge mechanism further includes a discharge control valve, which is disposed at the discharge port and is used to open and close the discharge port. In this way, when material discharge is not required or the air pressure in the receiving bin needs to be adjusted, the discharge port can be automatically closed, thereby improving the degree of automation of the device.

[0018] In some embodiments, the colloid defoaming device further comprises a shell, a partition and a heating element, wherein a cavity is arranged in the shell, the partition is arranged in the cavity and divides the cavity into a lower material bin and a receiving material bin stacked along a first direction, and the heating element is arranged on the cavity wall of the cavity and is used to increase the temperature in the cavity. In this way, the shell structure can be made compact and the space utilization rate in the shell is improved.

[0019] A colloid defoaming method includes the following steps: placing a rubber block in a material discharging bin, and heating and melting the rubber block into a colloid; outputting the colloid from the material discharging bin to a material receiving bin; adjusting the air pressure in the material receiving bin to a preset air pressure; and driving a stirring component to stir the colloid to eliminate bubbles in the colloid. In the above-mentioned colloid defoaming method, the colloid is output from the material discharging bin to the material receiving bin, and when the pressure regulating component adjusts the air pressure in the material receiving bin to a preset air pressure, it can be initially defoamed, and then the stirring component is used to stir the colloid to eliminate bubbles in the colloid for a second time. No defoaming agent is needed, and a better colloid defoaming effect can be achieved, which reduces the defoaming cost and improves the colloid discharge stability.

[0020] In some embodiments, in the step of placing the rubber block in the lower material bin and heating and melting the rubber block into a colloid, the heating temperature is set to 140°C to 150°C and the heating time is set to 2min to 3min. In this way, the solid rubber block can be quickly heated and melted into a liquid colloid, which is conducive to improving production efficiency.

[0021] In some embodiments, the step of adjusting the air pressure in the receiving bin to a preset air pressure includes: adjusting the air pressure in the receiving bin by vacuuming; and stopping vacuuming when the air pressure in the receiving bin reaches the preset air pressure, wherein the preset air pressure is 20 mbar to 100 mbar. In this way, when the air pressure in the receiving bin reaches the preset air pressure value, the air pressure adjustment in the receiving bin can be stopped in time, so that the colloid can be initially defoamed.

[0022] In some embodiments, in the step of driving the stirring component to stir the colloid to eliminate bubbles in the colloid, the stirring speed is set to 15r / min~20r / min, and the stirring time is 1min~2min. In this way, the bubbles in the colloid can be eliminated quickly, which is conducive to improving the bubble elimination rate in the colloid. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] Currently, in the production process of hot melt adhesive, stirring and defoaming agents are mostly used in combination to reduce bubbles in the hot melt adhesive, but the defoaming ability has an upper limit. During the use of hot melt adhesive, bubbles inside the hot melt adhesive during the flow and melting process will also bring certain risks to the hot melt adhesive coating, affecting the stability of subsequent glue output.

[0037] Based on the above considerations, after in-depth research, a colloid defoaming device and a colloid defoaming method were designed. The colloid is output from the lower silo to the receiving silo. When the pressure regulating component adjusts the air pressure in the receiving silo to the preset air pressure, it can be initially defoamed. Then the colloid is stirred by the stirring component to eliminate the bubbles in the colloid for a second time. No defoaming agent is used, and a better colloid defoaming effect can be achieved, which reduces the defoaming cost and improves the colloid discharge stability.

[0038] Please refer to Figure 1 The colloid defoaming device in one embodiment includes a feeding mechanism 100 and a defoaming mechanism 200. The feeding mechanism 100 includes a feeding bin 101. The defoaming mechanism 200 includes a receiving bin 201, a stirring assembly 300 and a pressure regulating assembly 400. The pressure regulating assembly 400 is connected to the receiving bin 201 and is used to adjust the air pressure in the receiving bin 201. The stirring assembly 300 is arranged in the receiving bin 201. The receiving bin 201 is connected to the feeding bin 101.

[0039] The receiving bin 201 is used to receive the colloid outputted from the unloading bin 101 , and after the pressure regulating component 400 adjusts the air pressure in the receiving bin 201 to a preset air pressure, the stirring component 300 stirs the colloid to eliminate bubbles in the colloid.

[0040] It should be noted that the colloid is a hot melt adhesive in a liquid state, and the glue block is a hot melt adhesive in a solid state. The colloid is discharged from the discharge bin 101 into the receiving bin 201, and then the receiving bin 201 is closed and the air pressure in the receiving bin 201 is adjusted. After the pressure regulating component 400 adjusts the air pressure in the receiving bin 201 to a preset pressure, the colloid is stirred by the stirring component 300 to eliminate bubbles in the discharged colloid.

[0041] In the embodiment of the present application, the unloading mechanism 100 is a component for storing and conveying hot colloid, that is, the unloading bin 101 can store and convey hot colloid, and the liquid colloid can be directly placed in the unloading bin 101 and heated before output, or the solid colloid block can be placed in the unloading bin 101 and heated and melted into liquid colloid before output. Among them, the unloading mechanism 100 includes not only the unloading bin 101, but also other components such as the heating component 110, so as to facilitate rapid heating or conveying of the colloid.

[0042] In the embodiment of the present application, the defoaming mechanism 200 is a component for eliminating bubbles in the colloid, and the defoaming mechanism 200 is arranged downstream of the feeding mechanism 100 to receive the colloid output by the feeding mechanism 100. The defoaming mechanism 200 and the feeding mechanism 100 can be arranged in a variety of ways, such as being stacked up and down, or being arranged side by side left and right.

[0043] In the embodiment of the present application, the receiving bin 201 is connected with the unloading bin 101, and the connection between the two can be realized through a variety of structural forms, for example: a partition 600 is provided between the receiving bin 201 and the unloading bin 101, and the partition 600 is both the top plate of the receiving bin 201 and the bottom plate of the unloading bin 101, and a through hole is provided on the partition 600, and the receiving bin 201 and the unloading bin 101 are connected through the through hole. Among them, the unloading bin 101 and the receiving bin 201 can be cylindrical cavities, rectangular cavities or other shapes, and the shapes of the unloading bin 101 and the receiving bin 201 are not specifically limited here.

[0044] In the embodiment of the present application, the stirring assembly 300 is a component for stirring the colloid, and the stirring assembly 300 is rotatably disposed in the receiving bin 201. The number of stirring assemblies 300 is not limited to one, that is, the number of stirring assemblies 300 can be at least two. The stirring assembly 300 can be in various structural forms, for example, the stirring assembly 300 includes a blade 322, and the blade 322 rotates to stir the colloid.

[0045] In the embodiment of the present application, the pressure regulating assembly 400 is a component for regulating the air pressure in the receiving bin 201. The pressure regulating assembly 400 is disposed in the receiving bin 201. The number of the pressure regulating assembly 400 is not limited to one, that is, the number of the pressure regulating assembly 400 can be at least two. The pressure regulating assembly 400 can regulate the air pressure in the receiving bin 201 in a variety of ways. For example, the pressure regulating assembly 400 includes a vacuum pump, and the air pressure in the receiving bin 201 is regulated by vacuuming.

[0046] In the above-mentioned colloid defoaming device, the colloid is output from the unloading bin 101 to the receiving bin 201. When the pressure regulating component 400 adjusts the air pressure in the receiving bin 201 to a preset pressure, it can initially defoam. Then, the stirring component 300 is used to stir the colloid to eliminate the bubbles in the colloid for a second time. No defoaming agent is needed, and a better colloid defoaming effect can be achieved, which reduces the defoaming cost and improves the colloid discharge stability.

[0047] According to some embodiments of this application, please refer to Figure 1 The pressure regulating assembly 400 includes a pressure regulating driving component 410 and a connecting pipe 420. The pressure regulating driving component 410 is located outside the material receiving bin 201, and the pressure regulating driving component 410 is connected to the material receiving bin 201 through the connecting pipe 420; the pressure regulating driving component 410 can generate negative pressure to adjust the air pressure in the material receiving bin 201.

[0048] It should be noted that one end of the connecting pipe 420 is connected to the pressure regulating driving member 410, and the other end of the connecting pipe 420 is connected to the material receiving bin 201. The pressure regulating driving member 410 is used as a power source. When the pressure regulating driving member 410 is in operation, negative pressure can be generated in the connecting pipe 420. Since the connecting pipe 420 is connected to the material receiving bin 201, negative pressure can also be generated in the material receiving bin 201. The air pressure in the material receiving bin 201 is adjusted by controlling the operation of the pressure regulating driving member 410.

[0049] In the embodiment of the present application, the pressure regulating driving member 410 is a power source component that generates negative pressure, for example, the pressure regulating driving member 410 is a vacuum pump, and the type of the vacuum pump can be an electromagnetic pump or a mechanical pump, and the type of the vacuum pump is not limited here. The number of the pressure regulating driving member 410 is not limited to one, that is, the number of the pressure regulating driving member 410 can be at least two.

[0050] In the embodiment of the present application, the connecting pipe 420 is a component for connecting the pressure regulating drive member 410 and the receiving bin 201. The connecting pipe 420 is preferably a hose, which can be suitable for installation spaces of different sizes. The connecting pipe 420 can be a hollow round tube, a hollow square tube or other shapes.

[0051] Through the above arrangement, the air pressure in the receiving bin 201 can be adjusted through the pressure regulating drive 410, which is convenient to operate and has a reasonable structure.

[0052] According to some embodiments of this application, please refer to Figure 1 The pressure regulating assembly 400 also includes a pressure detecting component 430, which is arranged in the material receiving bin 201 and is used to detect the air pressure in the material receiving bin 201; the colloid defoaming device also includes a controller electrically connected to the pressure detecting component 430 and the pressure regulating driving component 410, and the controller controls the operating state of the pressure regulating driving component 410 according to the air pressure detection value of the pressure detecting component 430.

[0053] It is understandable that the pressure detection component 430 can monitor the air pressure in the receiving bin 201 in real time. For example, before adjusting the air pressure in the receiving bin 201, the pressure detection component 430 detects the first air pressure value in the receiving bin 201, and then during the process of adjusting the air pressure value in the receiving bin 201 to the preset air pressure, the pressure detection component 430 monitors the air pressure in the receiving bin 201 in real time, and when the preset air pressure value is reached, the air pressure adjustment in the receiving bin 201 is stopped in time (for example, the pressure regulating driving component 410 is stopped).

[0054] In the embodiment of the present application, the pressure detection component 430 is a component for detecting the air pressure in the receiving bin 201. The number of the pressure detection components 430 is not limited to one. When the number of the pressure detection components 430 is at least two, each pressure detection component 430 can be arranged at a different position of the receiving bin 201 to improve the accuracy of the air pressure detection result. Optionally, the pressure detection component 430 is a pressure gauge or a pressure sensor.

[0055] Through the above-mentioned setting, the operating state of the pressure regulating drive component 410 can be controlled according to the air pressure detection value of the pressure detecting component 430, so that when the air pressure in the receiving bin 201 reaches the preset air pressure value, the air pressure regulation in the receiving bin 201 is stopped in time, so that the colloid can be initially defoamed.

[0056] According to some embodiments of this application, please refer to Figure 1 The pressure regulating assembly 400 also includes a pressure regulating control valve 440. The side wall of the receiving bin 201 is provided with a vacuum interface 201c connected to the connecting pipe 420. The pressure regulating control valve 440 is provided at the vacuum interface 201c and is used to open and close the vacuum interface 201c.

[0057] It should be noted that one end of the connecting tube 420 is provided at the vacuum interface 201c, and the other end of the connecting tube 420 is provided at the pressure regulating driving member 410, so that the pressure regulating driving member 410 is connected to the material receiving bin 201 through the connecting tube 420. When the air pressure of the material receiving bin 201 needs to be adjusted, the vacuum interface 201c is opened; when the air pressure of the material receiving bin 201 does not need to be adjusted, the vacuum interface 201c is closed.

[0058] In the embodiment of the present application, the pressure regulating control valve 440 is a valve member used to open and close the vacuum interface 201c. The number of the vacuum interface 201c is not limited to one. When the number of the vacuum interface 201c is at least two, each vacuum interface 201c is provided in a one-to-one correspondence with the pressure regulating control valve 440. Optionally, the pressure regulating control valve 440 is a solenoid valve that can automatically open or close the vacuum interface 201c.

[0059] Through the above arrangement, when the air pressure of the receiving bin 201 needs to be adjusted, the vacuum interface 201c can be automatically opened, thereby improving the automation level of the device.

[0060] According to some embodiments of this application, please refer to Figure 1 The material discharge bin 101 has a feed port 101a and a discharge port 101b which are relatively arranged along a first direction, and the material receiving bin 201 has a material receiving port 201a and a material discharge port 201b which are relatively arranged along the first direction. The material receiving port 201a is connected to the material discharge port 101b, and the stirring component 300 is located between the material receiving port 201a and the material discharge port 201b. The first direction is the axial direction of the material receiving bin 201.

[0061] It should be noted that the first direction is Figure 1 The X direction is the axial direction of the receiving bin 201. The solid rubber block enters the receiving bin 201 from the feed port 101a, and after being heated and melted into a liquid colloid in the receiving bin 201, the colloid is discharged from the discharge port 101b into the receiving bin 201, and then the discharge port 101b and the receiving port 201a are closed, so that the receiving bin 201 is in a closed state, and the air pressure in the receiving bin 201 is adjusted. After the pressure regulating component 400 adjusts the air pressure in the receiving bin 201 to a preset air pressure, the colloid is stirred by the stirring component 300 to eliminate bubbles in the discharged colloid.

[0062] In the embodiment of the present application, the feed bin 101 has a feed port 101a and a feed port 101b arranged opposite to each other along a first direction, that is, the feed port 101a and the feed port 101b are respectively located on opposite sides of the feed bin 101 along the first direction. The feed port 101a and the feed port 101b can be aligned or staggered, and the shapes of the feed port 101a and the feed port 101b can be square, circular or other shapes.

[0063] In the embodiment of the present application, the receiving bin 201 has a receiving port 201a and a discharging port 201b arranged opposite to each other along a first direction, that is, the receiving port 201a and the discharging port 201b are respectively located on opposite sides of the receiving bin 201 along the first direction. The receiving port 201a and the discharging port 201b can be aligned or staggered, and the shapes of the receiving port 201a and the discharging port 201b can be square, circular or other shapes.

[0064] Through the above arrangement, the dead angle of loading and unloading can be reduced, so that the colloid in the unloading bin 101 can be smoothly input into the receiving bin 201, which is beneficial to improving the defoaming efficiency of the colloid.

[0065] According to some embodiments of this application, please refer to Figure 1 The stirring assembly 300 includes a stirring driving member 310 and a stirring structure 320. The stirring structure 320 extends along a first direction, and the stirring driving member 310 is connected to the stirring structure 320. Driven by the stirring driving member 310, the stirring structure 320 can rotate around the central axis of the material bin 201.

[0066] It should be noted that the central axis direction of the receiving bin 201 is Figure 1 The X direction is the axial direction of the receiving bin 201 . Here, driven by the stirring driving member 310 , the stirring structure 320 rotates around the central axis of the receiving bin 201 to stir the colloid in the receiving bin 201 .

Each blade 322 can be arranged in a variety of ways, such as uniform arrangement, staggered arrangement or other arrangements of the blades 322. The size and shape of each blade 322 are preferably exactly the same to facilitate uniform stirring.

[0078] In an embodiment of the present application, the guide member 323 and the connecting shaft 321 can be an integrated structure, for example, integrally formed by injection molding, casting, etc., with good integrity and high mechanical strength; the guide member 323 and the connecting shaft 321 can also be a split structure, for example, fixed by snap-on, plug-in, etc.

[0079] Through the above arrangement, after the colloid is input into the receiving port 201a, it can be decelerated under the action of the flow guide 323 and flow smoothly into the receiving bin 201, which is beneficial to the transportation and defoaming of the colloid.

[0080] According to some embodiments of this application, please refer to Figure 1 , the guide member 323 is constructed as a conical structure.

[0081] It should be noted that since the outer diameter of the guide member 323 gradually increases in the direction from the receiving port 201a to the discharging port 201b, after the colloid is input into the receiving port 201a, it can be decelerated under the action of the guide member 323 and flow smoothly into the receiving bin 201, which is beneficial to the transportation and defoaming of the colloid.

[0088] Through the above arrangement, before the colloid is output from the receiving bin 201, impurities can be filtered through the first filter 324 and then stirred, and then output, thereby greatly reducing impurities and bubbles in the colloid.

[0089] According to some embodiments of this application, please refer to Figure 1 The material discharge mechanism 100 includes a heating component 110, which is disposed between the material feed port 101a and the material discharge port 101b and is used for heating and melting the rubber block.

[0090] It should be noted that the heating component 110 is disposed between the feed port 101a and the discharge port 101b. The solid rubber block is fed into the discharge bin 101 from the feed port 101a, heated and melted into a liquid colloid by the heating component 110 in the discharge bin 101, and then discharged.

[0099] It should be noted that, since the solid rubber block is heated and melted into a liquid colloid, impurities may exist in the colloid.

[0107] According to some embodiments of this application, please refer to Figure 1 The colloid defoaming device also includes a shell 500, a partition 600 and a heating element. The shell 500 is provided with a cavity, the partition 600 is arranged in the cavity, and divides the cavity into a lower material bin 101 and a receiving material bin 201 stacked along a first direction. The heating element is arranged on the cavity wall of the cavity and is used to increase the temperature in the cavity.

[0108] It can be understood that the partition 600 is both the top plate of the material receiving bin 201 and the bottom plate of the material discharging bin 101.

[0112] Please refer to Figure 2 and Figure 3 , the colloid defoaming method in one embodiment comprises the following steps:

[0113] S1, placing the rubber block in the lower material bin 101, and heating and melting the rubber block into a colloid;

[0114] S2, outputting the colloid from the unloading bin 101 to the receiving bin 201;

[0115] S3, adjusting the air pressure in the receiving bin 201 to a preset air pressure;

[0116] S4, driving the stirring component 300 to stir the colloid to eliminate bubbles in the colloid.

[0117] It should be noted that the colloid is a hot melt adhesive in liquid form. The colloid is discharged from the discharge bin 101 into the receiving bin 201, and then the receiving bin 201 is closed and the air pressure in the receiving bin 201 is adjusted. After the pressure regulating component 400 adjusts the air pressure in the receiving bin 201 to a preset pressure, the colloid is stirred by the stirring component 300 to eliminate bubbles in the discharged colloid.

[0118] In the embodiment of the present application, in step S1, the heating component 110 is disposed in the material discharge bin 101, and the solid rubber block is input into the material discharge bin 101, and is heated and melted into a liquid colloid by the heating component 110 in the material discharge bin 101 and then output.

[0119] In an embodiment of the present application, in step S3, when the pressure-regulating drive component 410 is in operation, negative pressure can be generated in the connecting pipe 420. Since the connecting pipe 420 is connected to the material receiving bin 201, negative pressure can also be generated in the material receiving bin 201. The air pressure in the material receiving bin 201 is adjusted by controlling the operation of the pressure-regulating drive component 410.

[0120] In the above-mentioned colloid defoaming method, the colloid is output from the unloading bin 101 to the receiving bin 201. When the pressure regulating component 400 adjusts the air pressure in the receiving bin 201 to a preset pressure, it can be initially defoamed. Then, the colloid is stirred by the stirring component 300 to eliminate the bubbles in the colloid for a second time. No defoaming agent is needed, and a better colloid defoaming effect can be achieved, which reduces the defoaming cost and improves the colloid discharge stability.

[0122] Through the above arrangement, the solid glue block can be quickly heated and melted into a liquid colloid, which is beneficial to improving production efficiency.

[0123] According to some embodiments of this application, please refer to Figure 3 The step S3 of adjusting the air pressure in the receiving bin 201 to a preset air pressure includes:

[0124] S3a, adjusting the air pressure in the receiving bin 201 by vacuuming;

[0125] S3b. When the air pressure in the receiving bin 201 reaches a preset air pressure, stop vacuuming, wherein the preset air pressure is 20 mbar to 100 mbar.

[0126] It can be understood that before adjusting the air pressure in the receiving bin 201, the first air pressure value in the receiving bin 201 is detected by the pressure detection component 430, and then during the process of adjusting the air pressure value in the receiving bin 201 to the preset air pressure, the air pressure in the receiving bin 201 is monitored in real time by the pressure detection component 430. When the preset air pressure value is reached, the air pressure adjustment in the receiving bin 201 is stopped in time (for example, the operation of the pressure regulating drive component 410 is stopped).

[0127] Through the above arrangement, when the air pressure in the receiving bin 201 reaches a preset air pressure value, the air pressure regulation in the receiving bin 201 can be stopped in time, so that the colloid can be initially defoamed.

[0128] According to some embodiments of this application, please refer to Figure 2 and Figure 3 In step S4 of driving the stirring component 300 to stir the colloid to eliminate bubbles in the colloid, the stirring speed is set to 15 r / min~20 r / min, and the stirring time is 1 min~2 min.
