Description

Technical Field

[0001] This invention belongs to the field of hot melt adhesive production technology, specifically relating to a filtration device for hot melt adhesive production. Background Technology

[0002] Hot melt adhesive is a type of malleable adhesive whose physical state changes with temperature within a certain temperature range, while its chemical properties remain unchanged. It is non-toxic, odorless, and an environmentally friendly chemical product. It is highly favored due to its solid nature, ease of packaging, transportation, and storage; its solvent-free, pollution-free, and non-toxic properties; its simple production process; high added value; and its strong and fast bonding speed.

[0003] The prior art includes a filter device for hot melt adhesive production with patent publication number CN219518009U. The aforementioned patent uses an inclined stirring rod to facilitate stirring of the hot melt adhesive and a brush that can brush the filter holes on the coarse filter layer during stirring to prevent them from clogging and affecting the filtration quality. However, in actual use, it still has the following shortcomings: From a practical point of view, hot melt adhesive production is an uninterrupted process, while the brush of this device needs to be used when the filtration device is stopped, resulting in low applicability.

[0004] Therefore, a filtration device for hot melt adhesive production is needed to solve the problems existing in the prior art.

[0005] new content

[0006] The purpose of this invention is to provide a filtration device for hot melt adhesive production to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a filtration device for hot melt adhesive production, comprising a filtration chamber, wherein a plurality of filtration components are fixedly connected to the upper inner surface of the filtration chamber, a power supply device is fixedly connected to the upper left side of the filtration chamber, a waste bin is fixedly connected to the left side of the filtration chamber, a connector is fixedly connected to the lower right side of the filtration chamber, support plates are fixedly connected to both sides of the upper end of the connector, a servo motor is fixedly connected to the middle of the support plate, a storage bin is fixedly connected to the upper end of the support plate, and a collection bin is fixedly connected to the lower end of the filtration chamber.

[0008] It should be noted in the solution that the waste bin and the connecting parts are both fixedly connected to support columns on both sides of the lower end.

[0009] It is worth noting that the filter chamber has a discharge trough in the middle of its lower end, and the upper surface of the filter chamber at the lower end is fixedly connected to both sides of the discharge trough. The first side plate is at a 45-degree angle to the plane, and several guide plates are fixedly connected to one side of the first side plate.

[0010] Furthermore, it should be noted that the power supply device includes a motor, and a plurality of output connection ports are provided on one side of the motor. Each of the plurality of output connection ports can be inserted into one end of a connecting wire, and a heating tube is fixedly connected to the other end of the connecting wire.

[0011] In a preferred embodiment, the plurality of filter components include filter tubes, each filter tube having a connecting plate fixedly connected to its upper end. The upper end of each connecting plate is fixedly connected to the lower surface of the upper end of the filter chamber. Each filter tube has a plurality of filter holes at its lower end. Each connecting plate has a discharge pipe fixedly connected to its left side, the other end of which is embedded in the waste bin. Each connecting plate has an inlet pipe fixedly connected to its right side, the other end of which is embedded in the storage bin. A turntable is slidably connected to the inner surface of the filter tube. A rotating shaft is fixedly connected to the center of the turntable. Both ends of the rotating shaft are slidably connected to one side of the discharge pipe or the inlet pipe, respectively. A support block is fixedly connected to the right side of the outer surface of the rotating shaft, and a second baffle is fixedly connected to its outermost end.

[0012] In a preferred embodiment, a sealing block is installed on the outer surface of the rotating shaft on either the discharge pipe or the feed pipe side.

[0013] In a preferred embodiment, the output end of the servo motor is engaged with a drive shaft, and the other end of the outer surface of the drive shaft is engaged with a connecting belt. Both ends of the connecting belt are engaged with the outer surface of the right side of the rotating shaft, and the outer surface of the drive shaft is fixedly connected to both ends of the connecting belt with a first baffle.

[0014] In a preferred embodiment, the lower end of the storage compartment is provided with several connecting holes, and a second side plate is fixedly connected to both sides of the lower end of the storage compartment on the several connecting holes, and the second side plate is symmetrically triangular.

[0015] Compared with the prior art, the filtration device for hot melt adhesive production provided by this invention has at least the following beneficial effects:

[0016] (1) The servo motor output drives the meshing drive shaft to rotate, the drive shaft drives the meshing connecting belt to rotate, the connecting belt rotates and drives several rotating shafts to rotate, thereby driving the turntable to rotate, so that the hot melt adhesive in the storage bin moves to the filter tube of the filter assembly. The hot melt adhesive drips onto the symmetrical first side plate through the filter hole at the lower end of the filter tube and finally reaches the collection bin. The hot melt adhesive that cannot pass through the filter hole 905 will enter the waste bin 2 through the discharge pipe 903. This can realize the automation of hot melt adhesive production filtration and improve the filtration efficiency of the hot melt adhesive production filtration device.

[0017] (2) The temperature of the heating tube is controlled by the power supply device. That is, the motor, output connection port and connection line on the side of the power supply device heat the heating tube, thereby ensuring the temperature during hot melt adhesive filtration. This prevents some hot melt adhesive from degrading at temperatures exceeding 200°C, or from solidifying at temperatures too low, which would affect the filtration effect and thus increase the practicality of the hot melt adhesive production filtration device.

[0024] The present invention will be further described below with reference to embodiments.

[0025] Please see Figure 1-5 This invention provides a filtration device for hot melt adhesive production, comprising: a filter chamber 1, a plurality of filter components 9 fixedly connected to the upper inner surface of the filter chamber 1, a power supply device 4 fixedly connected to the upper left side of the filter chamber 1, a waste bin 2 fixedly connected to the left side of the filter chamber 1, a connector 7 fixedly connected to the lower right side of the filter chamber 1, support plates 10 fixedly connected to both sides of the upper end of the connector 7, a servo motor 8 fixedly connected to the middle of the support plate 10, a storage bin 3 fixedly connected to the upper end of the support plate 10, and a collection bin 6 fixedly connected to the lower end of the filter chamber 1.

[0026] Further as Figure 1 As shown, it is worth noting that support columns 5 are fixedly connected to both sides of the lower end of the waste bin 2 and the connector 7. The stability of the filter device for hot melt adhesive production is increased by the support columns 5.

[0027] Further as Figure 3 As shown, it is worth noting that a discharge trough 103 is provided in the middle of the lower end of the filter chamber 1, and a first side plate 101 is fixedly connected to both sides of the discharge trough 103 on the upper surface of the lower end of the filter chamber 1. The first side plate 101 is at a 45-degree angle to the plane, and several guide plates 102 are fixedly connected to one side of the first side plate 101. The hot melt adhesive after filtration can easily enter the collection chamber 6 through the discharge trough 103, and the hot melt adhesive can easily enter the collection chamber 6 through the symmetrical first side plate 101 and several guide plates 102.

[0028] Further as Figure 2 and Figure 5 As shown, it is worth noting that the power supply device 4 includes a motor 401. Several output connection ports 402 are provided on one side of the motor 401. Each of the output connection ports 402 can be inserted into one end of a connecting wire 403. The other end of the connecting wire 403 is fixedly connected to a heating tube 404. The heating tube 404 is heated by the power supply device 4, i.e., the motor 401, output connection ports 402 and connecting wire 402 on one side of the power supply device 4. This ensures the temperature during hot melt adhesive filtration, preventing some hot melt adhesive from degrading at temperatures exceeding 200°C or solidifying at excessively low temperatures, thus affecting the filtration effect and increasing the practicality of the filtration device for hot melt adhesive production.

[0029] The solution has the following working process: the output end of the servo motor 8 drives the meshing drive shaft 801 to rotate, the drive shaft 801 drives the meshing connecting belt 803 to rotate, the connecting belt 803 drives several rotating shafts 907 to rotate, thereby driving the turntable 906 to rotate, so that the hot melt adhesive in the storage bin 3 moves to the filter tube 901 of the filter assembly 9. The hot melt adhesive drips onto the symmetrical first side plate 101 through the filter hole 905 at the lower end of the filter tube 901, and finally reaches the collection bin 6. The hot melt adhesive that cannot pass through the filter hole 905 will enter the waste bin 2 through the discharge pipe 903.

[0030] As can be seen from the above working process: the support column 5 increases the stability of the hot melt adhesive production filtration device; the discharge trough 103 facilitates the entry of the filtered hot melt adhesive into the collection chamber 6; and the symmetrical first side plate 101 and several guide plates 102 facilitate the entry of the hot melt adhesive into the collection chamber 6. The power supply device 4, namely the motor 401, output connection port 402 and connecting wire 403 on one side of the power supply device 4, heats the heating tube 404, thereby ensuring the temperature during hot melt adhesive filtration, preventing some hot melt adhesive from degrading at temperatures exceeding 200°C, or solidifying at temperatures too low, thus affecting the filtration effect and increasing the practicality of the hot melt adhesive production filtration device.

[0031] Further as Figure 4 As shown, it is worth noting that several filter components 9 include filter tubes 901, with connecting plates 902 fixedly connected to the upper ends of the filter tubes 901. The upper ends of the connecting plates 902 are fixedly connected to the lower surface of the upper end of the filter chamber 1. The lower ends of the filter tubes 901 are provided with several filter holes 905. The left side of the connecting plates 902 is fixedly connected to a discharge pipe 903, the other end of which is embedded inside the waste bin 2. The right side of the connecting plates 902 is fixedly connected to a feed pipe 904, the other end of which is embedded inside the storage bin 3. A turntable 906 is slidably connected to the inner surface of the filter tubes 901. A rotating shaft 907 is fixedly connected to the middle of the turntable 906. Both ends of the rotating shaft 907 are slidably connected to... A support block 909 is fixedly connected to one side of the discharge pipe 903 or the feed pipe 904, and the right side of the outer surface of the rotating shaft 907 is fixedly connected to the outermost end of the support block 909. The outermost end of the support block 909 is fixedly connected to the second baffle 910. By rotating a number of filter components 9, i.e. a number of rotating shafts 907, the turntable 906 can be rotated, thereby causing the hot melt adhesive in the storage bin 3 to move towards the filter tube 901 of the filter component 9. The hot melt adhesive drips onto the symmetrical first side plate 101 through the filter hole 905 at the lower end of the filter tube 901, and finally reaches the collection bin 6. The hot melt adhesive that cannot pass through the filter hole 905 will enter the waste bin 2 through the discharge pipe 903. This can realize the automation of hot melt adhesive production filtration and improve the filtration efficiency of the hot melt adhesive production filtration device.

[0032] Further as Figure 4 As shown, it is worth noting that a sealing block 908 is installed on the outer surface of the rotating shaft 907 on either the side of the discharge pipe 903 or the feed pipe 904. The sealing block 908 increases the airtightness of the filter assembly 9.

[0033] Further as Figure 3As shown, it is worth noting that the output end of the servo motor 8 is engaged with a drive shaft 801, and the other end of the outer surface of the drive shaft 801 is engaged with a connecting belt 803. Both ends of the connecting belt 803 are engaged with the outer surface of the right side of the rotating shaft 907. The outer surface of the drive shaft 801 is fixedly connected to both ends of the connecting belt 803. The servo motor 8, that is, the output end of the servo motor 8 drives the engaged drive shaft 801 to rotate. The drive shaft 801 drives the engaged connecting belt 803 to rotate. The rotation of the connecting belt 803 drives the rotation of several rotating shafts 907.

[0034] Further as Figure 3 As shown, it is worth noting that the lower end of the storage compartment 3 is provided with several connecting holes 302, and the inner surface of the lower end of the storage compartment 3 is fixedly connected to the second side plate 301 on both sides of the several connecting holes 302. The symmetrical second side plate 301 is triangular. The second side plate 301 at the lower end of the storage compartment 3 facilitates the hot melt adhesive to enter the filter tube 901 of the filter assembly 9 for filtration.

[0035] In summary: The servo motor 8 drives the meshing drive shaft 801 to rotate, which in turn drives the meshing connecting belt 803 to rotate. The rotation of the connecting belt 803 drives several rotating shafts 907 to rotate, which in turn drives the turntable 906 to rotate. This causes the hot melt adhesive in the storage bin 3 to move towards the filter tube 901 of the filter assembly 9. The hot melt adhesive drips through the filter holes 905 at the lower end of the filter tube 901 onto the symmetrical first side plate 101, and finally reaches the collection bin 6. The hot melt adhesive that cannot pass through the filter holes 905 will enter the waste bin 2 through the discharge pipe 903. After passing through the several filter assemblies 9, i.e., the several rotating shafts 907, the rotation of the turntable 906 will drive the storage bin 3 to rotate. The hot melt adhesive inside moves towards the filter tube 901 of the filter assembly 9. The hot melt adhesive drips onto the symmetrical first side plate 101 through the filter hole 905 at the lower end of the filter tube 901, and finally reaches the collection bin 6. The hot melt adhesive that cannot pass through the filter hole 905 will enter the waste bin 2 through the discharge pipe 903. This can realize the automation of hot melt adhesive production filtration and improve the filtration efficiency of the hot melt adhesive production filtration device. The sealing block 908 increases the airtightness of the filter assembly 9. The servo motor 8, that is, the output end of the servo motor 8 drives the meshing drive shaft 801 to rotate. The drive shaft 801 drives the meshing connecting belt 803 to rotate. The rotation of the connecting belt 803 drives several rotating shafts 907 to rotate.
