Description

Technical Field

[0001] This utility model relates to the technical field of hot melt adhesive granulators, specifically to a low-temperature polyester hot melt adhesive anti-sticking granulator. 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. Because it is a solid, it is easy to package, transport, and store; it is solvent-free, pollution-free, and non-toxic; and its production process is simple, resulting in high added value and strong adhesion.

[0003] Hot melt adhesives are favored for their high strength and fast processing speed. In the production process of hot melt adhesives, a granulator is needed to cut hot melt adhesive strips into granules for subsequent use and storage. However, in the existing granulator process, the hot melt adhesive strips contain a lot of moisture when they come out of the cooling tank. This moisture reduces the surface energy of the hot melt adhesive when the cutter cuts the strips, making the adhesive more likely to wet the surface of the metal blade and form a viscous liquid film. This makes it easier for the hot melt adhesive to spread and adhere to the cutter surface. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a low-temperature polyester hot melt adhesive anti-sticking granulator that can remove moisture from the hot melt adhesive strip and solve the problem of hot melt adhesive particles easily sticking to the cutter.

[0005] The technical solution adopted in this utility model is a low-temperature polyester hot melt adhesive anti-sticking granulator, including a rotary cutting box. The rotary cutting box is provided with more than one set of support rods. The top of the support rods is connected to a second fixed shaft. A second transmission roller is sleeved on the second fixed shaft. The rotary cutting box is installed on a base. A glue strip conveying device is also installed on the base. Above and below the glue strip conveying device, there are a total of 4 sets of glue strip water absorption devices with the same structure and symmetrical arrangement. The lower glue strip water absorption device is installed on the base, and the upper glue strip water absorption device is installed on a mounting top plate. The four corners of the bottom end of the mounting top plate are connected to long pillars fixed on the base. Two long pillars on one side are fixedly connected to a fan mounting plate and a water receiving tank. A blower is installed on the bottom end of the fan mounting plate above the water receiving tank. A first fixed shaft is fixed at both ends in the water receiving tank. A first transmission roller is sleeved on the first fixed shaft. A water outlet is provided on one side of the bottom end of the water receiving tank. A buzzer and an electrical control cabinet are installed on the front of the base. A control panel is provided above the electrical control cabinet.

[0006] The rotary cutting box is equipped with a first motor, which is connected to a rotating shaft. A cutter is mounted on the rotating shaft. The rotary cutting box has a discharge hopper, a portion of which extends outside the box. The bottom of the discharge hopper inside the box is connected to a support leg. The top of the discharge hopper inside the box has a discharge port. A guide plate fixed to the discharge hopper is located around the discharge port. The guide plate has a right-angled triangular side profile. The top wall of the rotary cutting box above the discharge hopper has a feed inlet, and a feed pipe is installed at the feed inlet. The portion of the discharge hopper outside the box is connected to the conveying device of the screening device.

[0007] The described rubber strip conveying device includes four short pillars fixed on a base. The tops of two short pillars on the same side are connected to side support plates. Bearings are installed inside the side support plates. Two support seats are installed on one side of the side support plate, and each support seat is equipped with a drive motor. The drive motor is connected to a drive shaft. The drive shaft passes through the bearings on both sides and is connected to a drive pulley. The drive pulley is connected to a driven pulley via a belt. The driven pulley is connected to a driven shaft. The driven shaft is also fixedly connected to two other bearings. The same drive rollers are fixedly fitted on the driven shaft and the drive shaft. The drive rollers are provided with multiple annular holes.

[0008] The second and first drive rollers are the same in size and structure as the drive rollers.

[0009] The described adhesive strip water-absorbing device includes an electric actuator connected to a lifting box. The lifting box contains a displacement device connected to a moving rod. The moving rod passes through the lifting box and connects to a moving plate. Multiple insert rods are located on one side of the moving plate, each insert rod being inserted into a socket located on both sides of the mounting plate. A water-absorbing sponge is fixed to the mounting plate, with an embedding hole on one side of the sponge. A fixing plate is fixed to the other side of the moving plate, and a humidity detection probe is mounted on the fixing plate, embedding itself in the embedding hole.

[0010] The displacement device includes a motor support and a slide groove fixed inside the lifting box. A second motor is installed on the motor support. The second motor is connected to a bidirectional threaded rod. The bidirectional threaded rod is threaded to two identical moving blocks. One end of each moving block is connected to a slide rod. The slide rod is connected to a slider located in the slide groove. The other end of each moving block is connected to a moving rod. The moving rod passes through a moving limit hole located on the lifting box.

[0011] Each humidity detection probe is electrically connected to a different microcontroller in the control cabinet, and each microcontroller is electrically connected to a different buzzer. The number of humidity detection probes, microcontrollers, and buzzers are all the same.

[0012] The lower electric actuator is mounted on the base, and the upper electric actuator is mounted on the bottom end of the mounting plate.

[0013] The control panel is electrically connected to the first motor, the blower fan, the electric actuator, the second motor, and the drive motor.

[0014] The beneficial effects of this utility model are as follows: This utility model is equipped with a water receiving tank, a first transmission roller, a first fixed shaft, a blower, a fan mounting plate, and a glue strip water absorption device. The blower can blow most of the water droplets on the hot melt glue strip that has passed through the water receiving tank into the water receiving tank. Then, the glue strip water absorption device absorbs the remaining water droplets on the hot melt glue strip, which can effectively remove the moisture on the hot melt glue strip entering the rotary cutting box. This solves the problem that when the hot melt glue strip comes out of the cooling tank, it contains a lot of moisture, which causes the cutter to reduce the surface energy of the hot melt glue when cutting the hot melt glue strip. This makes the glue more likely to wet the surface of the metal blade and form a viscous liquid film, making the hot melt glue easier to spread and adhere to the cutter surface.

[0015] In this invention, the electric push rod in the adhesive strip water absorption device can control the height position of the lifting box, while the displacement device inside the lifting box can drive the moving rods, moving plates, insert rods, fixing plates and humidity detection probes on both sides to move simultaneously, which facilitates the installation and replacement of the insert plate and water-absorbing sponge, and ensures that the adhesive strip water absorption device can always maintain a good water absorption effect.

[0016] In this invention, the microcontroller inside the electrical control cabinet can read the data detected by the corresponding electrically connected humidity detection probe in real time. When the humidity reaches the set threshold, it can control the buzzer electrically connected to it to sound an alarm, reminding the staff to replace the absorbent sponge in time. When different buzzers sound an alarm, the staff can know which group of adhesive strip absorbent devices needs to replace the absorbent sponge, thus improving the efficiency of absorbent sponge replacement.

The same drive roller 49 is fixedly sleeved on the driven shaft 53 and the drive shaft 50. The drive roller 49 is provided with multiple annular holes 54.

[0031] The second drive roller 30 and the first drive roller 12 are the same in size and structure as the drive roller 49.

[0032] The described adhesive strip water-absorbing device includes an electric push rod 24, which is connected to a lifting box 25. A displacement device is provided inside the lifting box 25, and the displacement device is connected to a moving rod 23. The moving rod 23 passes through the lifting box 25 and connects to a moving plate 22. Multiple insertion rods 38 are provided on one side of the moving plate 22, and each insertion rod 38 is inserted into an insertion hole 47 located on both sides of a mounting plate 21. A water-absorbing sponge 20 is fixed on the mounting plate 21, and an embedding hole 46 is provided on one side of the water-absorbing sponge 20. A fixing plate 26 is fixed on the other side of the moving plate 22, and a humidity detection probe 27 is installed on the fixing plate 26, embedding the humidity detection probe 27 into the embedding hole 46.

[0033] The displacement device includes a motor support 41 and a slide groove 42 fixed inside the lifting box 25. A second motor 40 is installed on the motor support 41. The second motor 40 is connected to a bidirectional threaded rod 39. The bidirectional threaded rod 39 is threadedly connected to two identical moving blocks 37. One end of each moving block 37 is connected to a slide rod 43. The slide rod 43 is connected to a slider 44 located in the slide groove 42. The other end of each moving block 37 is connected to a moving rod 23. The moving rod 23 passes through a moving limiting hole 45, which is located on the lifting box 25.

[0034] Each humidity detection probe 27 is electrically connected to a different microcontroller in the electrical control cabinet 5, and each microcontroller is electrically connected to a different buzzer 7. The number of humidity detection probes 27, the number of microcontrollers, and the number of buzzers 7 are all the same.

[0035] The lower electric actuator 24 is mounted on the base 1, and the upper electric actuator 24 is mounted on the bottom end of the mounting top plate 17.

[0036] The control panel 4 is electrically connected to the first motor 3, the blower 14, the electric push rod 24, the second motor 40, and the drive motor 51.

[0037] When this low-temperature polyester hot melt adhesive anti-sticking granulator is in use, the hot melt adhesive strip will first pass through the first transmission roller 12, then through the drive roller 49 and the second transmission roller 30, and enter the rotary cutting box 28 from the feed pipe 32 for granulation. The cut hot melt adhesive particles will flow out from the discharge bucket 35, and then be conveyed to the screening device for screening by the conveying device of the screening device.

[0038] When the hot melt adhesive strip is conveyed on the two first drive rollers 12, the blower 14 is started and the air force is controlled within a suitable range. The air blown out by the blower 14 will blow most of the moisture on the hot melt adhesive strip into the water tank 10, and then discharge it from the water outlet 11 to the external water receiving device, so that most of the moisture on the hot melt adhesive strip is removed.

[0039] When the hot melt adhesive strip is conveyed on the two sets of drive rollers 49, the electric push rod 24 is activated. The electric push rod 24 can drive the lifting box 25 to move towards the hot melt adhesive strip. When the lifting box 25 moves, the displacement device inside can drive the moving rod 23 to move synchronously. The moving rod 23 can drive the moving plate 22 to move, causing the insertion rod 38 to move. The movement of the insertion rod 38 can drive the mounting plate 21 to move, causing the water-absorbing sponge 20 to move. When the water-absorbing sponges 20 on the upper and lower sides move to the position of the hot melt adhesive strip, they can absorb the residual moisture on the hot melt adhesive strip, thus absorbing the residual moisture of the hot melt adhesive strip.

[0040] When the drive roller 49 needs to be started, the drive motor 51 is started. The drive motor 51 drives the drive shaft 50 to rotate, causing the drive pulley 9 to rotate. The drive pulley 9 will drive the driven pulley 19 to rotate through the belt 18, causing the driven shaft 53 to rotate, thereby making the driven shaft 53 and the drive roller 49 on the drive shaft 50 rotate synchronously.

[0041] After the hot melt adhesive strip with its surface moisture removed enters the rotary cutting box 28 through the feed pipe 32, the first motor 3 is started. The first motor 3 drives the rotating shaft 2 to rotate, causing the cutter 33 to rotate. The rotating cutter 33 will cut the hot melt adhesive strip. The cut hot melt adhesive particles will enter the discharge bucket 35 from the discharge port 55, and then flow out from the discharge bucket 35 to the conveying device on the external screening device.

[0042] When the absorbent sponge 20 absorbs the residual moisture on the surface of the hot melt adhesive strip, the humidity detection probe 27 can detect the moisture content inside the absorbent sponge 20 in real time. When the humidity detection probe 27 detects that the moisture content inside the absorbent sponge 20 reaches the set threshold, the humidity detection probe 27 will transmit the signal to the microcontroller in the electrical control cabinet 5. The microcontroller will then control the corresponding buzzer 7 to sound an alarm, prompting the staff to replace the absorbent sponge 20.

[0043] When the absorbent sponge 20 needs to be replaced, start the electric actuator 24 to reset it, then start the second motor 40. The second motor 40 will drive the bidirectional threaded rod 39 to rotate, causing the moving blocks 37 on both sides to move to both sides simultaneously. The moving blocks 37 will drive the moving rod 23 to move, causing the moving plate 22 to move. The moving plate 22 will then drive the insert rod 38 and the fixing plate 26 to move simultaneously. The fixing plate 26 will drive the humidity detection probe 27 to move. When the insert rod 38 moves out of the mounting plate 21 and the humidity detection probe 27 moves out of the absorbent sponge 20, the mounting plate 21 and the absorbent sponge 20 can be removed. Then take out the new mounting plate 21 and the absorbent sponge 20, align the embedding hole 46 with the humidity detection probe 27, and then start the second motor 40 to rotate in the opposite direction, causing the moving blocks 37 on both sides to move to the center simultaneously. The new mounting plate 21 and the absorbent sponge 20 can then be installed. Then start the electric actuator 24 to continue the water absorption operation of the hot melt adhesive strip.

[0044] In this invention, a water receiving tank 10, a first transmission roller 12, a first fixed shaft 13, a blower 14, a fan mounting plate 15, and a glue strip water absorption device are provided. The blower 14 can blow most of the water droplets on the hot melt glue strip that has passed through the water receiving tank 10 into the water receiving tank 10. Then, the glue strip water absorption device absorbs the remaining water droplets on the hot melt glue strip, which can effectively remove the moisture on the hot melt glue strip entering the rotary cutting box 28. This solves the problem that when the hot melt glue strip comes out of the cooling tank, it contains a lot of moisture, which causes the cutter 33 to reduce the surface energy of the hot melt glue when cutting the hot melt glue strip. This makes the glue more likely to wet the surface of the metal blade and form a viscous liquid film, making it easier for the hot melt glue to spread and adhere to the surface of the cutter 33.

[0045] In this invention, the electric push rod 24 in the adhesive strip water absorption device can control the height position of the lifting box 25, while the displacement device inside the lifting box 25 can drive the moving rods 23, moving plate 22, insert rod 38, fixing plate 26 and humidity detection probe 27 on both sides to move simultaneously, which facilitates the installation and replacement of the insert plate 21 and water-absorbing sponge 20, and ensures that the adhesive strip water absorption device can always maintain a good water absorption effect.

[0046] In this invention, the microcontroller inside the electrical control cabinet 5 can read the data detected by the corresponding electrically connected humidity detection probe 27 in real time. When the humidity reaches the set threshold, it can control the buzzer 7 electrically connected to it to sound an alarm, reminding the staff to replace the absorbent sponge 20 in time. When different buzzers 7 sound an alarm, the staff can know which group of adhesive strip absorbent devices' absorbent sponges 20 need to be replaced, thus improving the efficiency of replacing the absorbent sponges 20.

Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively describe all possible implementations.
