Description

Technical Field

[0001] The present invention relates to the technical field of hot melt adhesive production, and in particular to a hot melt adhesive production and processing device and a processing method. Background Art

[0002] Hot melt adhesive is a polymer material widely used in packaging, bonding, sealing and other fields. Its production and processing process has a vital impact on product quality and performance. In the production and processing of hot melt adhesive, the cooling and molding of hot melt adhesive sticks is particularly critical. However, traditional hot melt adhesive production and processing equipment usually uses a tilted water injection method to cool the hot melt adhesive sticks. That is, after the hot melt adhesive sticks are extruded, they are tilted into the cooling pool for cooling. This tilted water injection cooling method has obvious drawbacks:

[0003] Uneven cooling: When the hot melt glue stick tilts into the cooling pool, its contact area with the cooling water is uneven, resulting in inconsistent cooling rates and prone to localized over- or under-cooling. This uneven cooling phenomenon can cause stress differences within the hot melt glue stick, which in turn affects its mechanical properties and appearance quality.

[0004] Prone to bending and deformation: Because hot-melt adhesive sticks are still hot after extrusion, they are physically soft. As they tilt into the cooling pool, the hot-melt adhesive sticks are subject to the combined forces of gravity and water flow, causing them to bend to one side. This deformation not only affects the appearance of the hot-melt adhesive stick but can also result in dimensional inaccuracies that do not meet requirements, affecting subsequent use.

[0005] Moreover, due to the problems of uneven cooling and easy deformation, the bent hot melt glue sticks cannot be arranged tightly during packaging, resulting in a significant reduction in packaging space utilization.

[0006] Therefore, the prior art lacks a production and processing device and method that can effectively solve the problems of uneven cooling and bending deformation caused by the hot melt glue stick tilted into the water. Summary of the Invention

[0007] In view of the deficiencies of the prior art, the present invention provides a hot melt adhesive production and processing device and method, which solves the problem of uneven cooling and easy bending and deformation of the existing hot melt adhesive during production as mentioned in the background art.

[0008] To achieve the above objectives, the present invention is implemented through the following technical solutions: a hot melt adhesive production and processing device and processing method, comprising:

[0009] Controller, used to control the entire device;

[0010] Screw extruder, used to extrude hot melt adhesive;

[0011] Also includes:

[0012] A cooling mechanism is located at the bottom of the screw extruder and is filled with cooling water for cooling the hot melt adhesive discharged from the screw extruder;

[0013] A traction mechanism, installed inside the cooling mechanism, for traction of the hot melt adhesive;

[0014] A cutting mechanism, located below the traction mechanism, is used to cooperate with the traction mechanism to cut off the hot melt glue stick;

[0015] A conveyor belt is installed at the bottom of the cooling mechanism and is used to output the hot melt glue sticks;

[0016] The collecting trough is installed at one end of the cooling mechanism and is used to collect the hot melt glue sticks output by the conveyor belt.

[0017] Preferably, the cooling mechanism includes a circulation assembly and a cooling assembly. The cooling assembly is installed within the circulation assembly. The circulation assembly is used to circulate cooling water, and the cooling assembly is used to cooperate with the circulation assembly to cool the hot melt adhesive. The synergistic effect of the circulation assembly and the cooling assembly achieves efficient circulation of cooling water and uniform cooling of the hot melt adhesive. The circulation assembly utilizes components such as a water pump, radiator, and nozzle to circulate cooling water within the cooling tank, ensuring that the cooling water remains at a low temperature and preventing the cooling effect from being affected by rising water temperature.

[0018] Preferably, the circulation assembly includes a cooling trough with a partition welded inside. The partition is used to divide the interior of the cooling trough into two upper and lower chambers. A water inlet is provided at the bottom of one end of the partition, which is connected to the input of a water pump. The water pump is mounted on the top of the partition. The output of the water pump is connected to a radiator via a connecting pipe. The radiator is fixed to the top of the cooling trough. A fan is installed on one side of the radiator, and the radiator is connected to a nozzle via a water outlet pipe. The partition design inside the cooling trough divides the cooling trough into two upper and lower chambers, achieving stratified recycling of cooling water. Cooling water from the bottom is pumped out by the water pump, cooled by the radiator, and then sprayed into the upper chamber through the nozzle, forming an efficient cooling water circulation system. This design not only ensures that the cooling water can maintain a low temperature, preventing the cooling effect from decreasing due to rising water temperature, but also further enhances the cooling effect through the cooperation of the radiator and fan. In addition, the water circulation accelerates the heat exchange efficiency of the hot melt adhesive stick, enhancing the third cooling effect of the hot melt adhesive stick.

[0019] Preferably, the cooling component includes a telescopic tube, and three telescopic tubes are provided. The bottom ends of the three telescopic tubes are connected to the partition, the top ends of the telescopic tubes are connected to the connecting plate, the outer side of the connecting plate is slidably connected to the limit rod, the bottom end of the limit rod is fixedly connected to the partition, and the top end of the limit rod is provided with a protruding structure, connecting arms are installed on both sides of the connecting plate, and the top ends of the connecting arms are connected to the floating plate by bolts, and the inside of the floating plate is filled with foam; the foam filled in the floating plate can adaptively adjust the height of the telescopic tube according to the liquid level, ensuring that the top end of the telescopic tube maintains a certain distance from the liquid level, so that the hot melt adhesive can be cooled for a second time after air cooling, avoiding direct entry into the telescopic tube for rapid cooling, and at the same time ensuring that water can still enter the telescopic tube for circulation when the liquid level drops.

[0020] Preferably, one end of the partition is in an inclined structure, and a filter plate is provided on the top of one end of the partition. Both sides of the filter plate are connected to the cooling trough by bolts. There are multiple filter plates, and the filter plates are distributed at equal intervals. The multiple filter plates distributed at equal intervals on the top of the partition can effectively filter impurities and particles in the cooling water and prevent these impurities from entering the cooling water circulation system.

[0021] Preferably, the traction mechanism includes a drive motor, which is mounted on the outside of the cooling trough via bolts, and the output end of the drive motor is key-connected to a transmission wheel. Two transmission wheels are provided, and the two transmission wheels are connected to each other via a connecting shaft. The transmission wheel is connected to a traction shaft via a transmission belt. One end of the traction shaft is rotatably connected to a positioning shaft, and a clamping shaft is provided on one side of the traction shaft. Through the coordinated action of the drive motor, transmission wheel, connecting shaft, transmission belt, and traction shaft, stable traction of the hot melt adhesive is achieved. The drive motor provides power, which drives the traction shaft to rotate through the transmission of the transmission wheel and connecting shaft, and the connection of the transmission belt, thereby clamping and traction of the hot melt adhesive via the clamping shaft. This ensures that the hot melt adhesive can move smoothly downward after cooling and forming.

[0022] Preferably, the clamping shaft is a three-section structure, and each section is rotatably connected to each other, a fixing rod is inserted into the two ends of the clamping shaft, one end of the fixing rod is connected to the cooling groove, and a connecting nut is installed at one end of the cooling groove, a connecting nut is provided on one side of the clamping shaft, and the connecting nut is sleeved on the outside of the fixing rod, and a first spring is also sleeved on the outside of the fixing rod, and an adjusting nut is provided at one end of the first spring, and the adjusting nut is threadedly connected to the outer wall of the fixing rod; the setting of the first spring can provide an elastic clamping force for the clamping shaft to avoid the hot melt glue stick being broken or deformed due to excessive clamping force, and at the same time, the elastic force of the spring can be flexibly adjusted by adjusting the nut to adapt to hot melt glue sticks of different specifications and hardness, further improving the versatility and adaptability of the equipment, and the components in the cooling water of this equipment have been waterproofed.

[0023] Preferably, the cutting mechanism includes a cylinder, a telescopic block is mounted on the outside of the telescopic end of the cylinder, a blade is mounted on one side of the telescopic block, and the telescopic block is connected to the slider via a slide rod, the slider is slidably connected to the inner wall of the cooling groove, a second spring is arranged between the slider and the telescopic block, and a top block is arranged on one side of the second spring, the cylinder is mounted on the top of the lifting plate, the lifting plate is slidably connected to the guide rod, the guide rod is welded to the inside of the cooling groove, and the bottom of the lifting plate is connected to the telescopic end of the hydraulic cylinder, the hydraulic cylinder is embedded in the bottom of the cooling groove, and a third spring is mounted on the outside of the telescopic end of the hydraulic cylinder; the cutting mechanism achieves precise cutting of the hot melt adhesive through the coordinated action of the cylinder, telescopic block, blade, slider, second spring, lifting plate, hydraulic cylinder and third spring. The cylinder pushes the telescopic block to drive the blade to perform the cutting action, and the hydraulic cylinder drives the lifting plate to move downward synchronously, so that the blade can cut synchronously with the movement of the hot melt adhesive, avoiding the interference of the blade with the hot melt adhesive during the cutting process, thereby effectively preventing the hot melt adhesive from bending and deforming during cutting.

[0024] Preferably, the steps are as follows:

[0025] Hot melt adhesive extrusion: The hot melt adhesive is extruded downwards through a screw extruder;

[0026] Cooling process: The fan on one side of the radiator is used to air-cool the extruded hot melt adhesive. The hot melt adhesive enters the cooling water in the cooling tank for secondary cooling and shaping. The hot melt adhesive enters the telescopic tube and is cooled a third time through the cooling water circulation system. After being cooled by the radiator under the action of the water pump, the cooling water is ejected from the nozzle and flows through the telescopic tube to quickly exchange heat and cool the hot melt adhesive.

[0027] Traction molding: The cooled and formed hot melt adhesive is pulled by the traction mechanism. The traction mechanism drives the transmission wheel to rotate through the driving motor, and then drives the traction shaft to rotate. The traction shaft and the clamping shaft cooperate to pull the hot melt adhesive. The clamping shaft elastically clamps the hot melt adhesive through the first spring to prevent the hot melt adhesive from being broken due to excessive clamping force.

[0028] Cutting and segmenting: After the hot melt adhesive is pulled by the traction mechanism, it passes through the inside of the cutting mechanism. The cylinder pushes the telescopic block to drive the blade to cut the hot melt adhesive. At the same time, the hydraulic cylinder drives the lifting plate to move downward synchronously, so that the cylinder and the blade move downward synchronously with the hot melt adhesive. After cutting, the cylinder and the hydraulic cylinder quickly reset and continue the next cutting action;

[0029] Transport and collection: After being cut and segmented, the hot melt adhesive is transported to the collection tank via a conveyor belt for collection.

[0030] The present invention provides a hot melt adhesive production and processing device and method. It has the following beneficial effects:

[0031] The hot melt adhesive production and processing device and its processing method extrude the hot melt adhesive downward through a screw extruder, and uses a fan on one side of the radiator for air cooling, while promoting air circulation in the radiator to achieve primary cooling of the hot melt adhesive; the hot melt adhesive then enters the cooling water in the cooling tank for secondary cooling and shaping; finally, the hot melt adhesive enters the interior of the telescopic tube, and the cooling water is driven by a water pump to circulate between the radiator and the nozzle. The water cooled by the radiator flows through the interior of the telescopic tube at high speed, performing a third rapid heat exchange cooling on the hot melt adhesive. The formed hot melt adhesive is evenly segmented by a traction mechanism and a cutting mechanism, and then transported to a collection tank by a conveyor belt. The device adopts a three-stage cooling and molding process, which effectively reduces the probability of deformation of the hot melt adhesive during the cooling process. At the same time, the vertical discharging cooling molding method further reduces the risk of the hot melt adhesive bending and deforming to one side compared to the traditional inclined water entry method.

[0044] The hot melt adhesive production and processing device can effectively solve the problems of uneven cooling and easy bending deformation in the existing hot melt adhesive production process by setting the cooling mechanism 3, the traction mechanism 4, the cutting mechanism 5, the conveying belt 6 and the collecting groove 7. The cooling mechanism 3 can uniformly cool the hot melt adhesive, avoiding stress difference and deformation caused by inconsistent local cooling speed. The device adopts the vertical water entry mode, which greatly reduces the probability of hot melt adhesive cooling deformation compared with the traditional inclined water entry, avoids the problem of hot melt adhesive bending to one side due to inclined water entry, and improves the cooling efficiency and product quality, and improves the production efficiency.

[0047] When the device of this embodiment is in use, the screw extruder 2 can extrude the hot melt adhesive downward, and then it is cooled by the fan 307 on one side of the radiator 306.

When the water cooled by the radiator 306 flows through the inside of the telescopic block 502 at a high speed, it can quickly exchange heat with the glue stick inside the telescopic end, thereby performing a third further cooling.
