Description

Technical Field

[0001] This utility model relates to the field of hot melt adhesive generation technology, specifically a hot melt adhesive cooling and molding device. Background Technology

[0002] Hot melt adhesive is an adhesive that is solid at room temperature, melts into a liquid state upon heating for application, and then rapidly bonds upon cooling. In its production process, cooling from the molten state to solid particles or strips is a key process step. The efficiency and uniformity of the cooling process directly determine the final properties of the hot melt adhesive, such as cohesive strength, crystallinity, shape stability, and whether internal defects will occur.

[0003] Publication number CN222115789U discloses a cooling and molding device for hot melt adhesive production. It uses equally spaced limiting rollers within a tank to prevent the hot melt adhesive rods from warping. A motor-driven auger churns the cooling water in the tank to prevent localized overheating. Finally, a vortex air pump at the end of the cooling water tank blows air to dry the hot melt adhesive rods. However, this device only completes a basic cooling process of "water cooling + simple air drying." Furthermore, this patent has the following problems in practical use: Firstly, the cooling method is simplistic and insufficient in depth, relying solely on primary water cooling and short-range end-point air drying, lacking a secondary, enhanced cooling stage. This makes it prone to uneven cooling due to insufficient dissipation of residual heat within the hot melt adhesive, thus affecting subsequent molding accuracy. Secondly, there is a lack of automated integration and quality control capabilities. There is no dedicated feeding and transfer mechanism, requiring manual assistance for feeding and conveying the hot melt adhesive sticks. Furthermore, no online detection unit is installed, making it impossible to monitor key parameters such as temperature and shape of the cooled hot melt adhesive in real time, hindering the rapid identification and rejection of defective products. Thirdly, the production process lacks completeness. After cooling and air drying, there is no corresponding automated finished product collection unit, requiring manual handling and collection of finished hot melt adhesive products. This not only increases labor costs but also easily damages finished products due to manual operation, significantly reducing overall production efficiency and failing to meet the demands of large-scale, automated hot melt adhesive production.

[0004] Therefore, a hot melt adhesive cooling molding device is proposed to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide a hot melt adhesive cooling and molding device to solve the three major problems mentioned in the background art: insufficient cooling, low degree of automation, and incomplete production process in the current hot melt adhesive cooling and molding process, which seriously affect product quality and production efficiency and make it difficult to meet the needs of large-scale production.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a hot melt adhesive cooling and molding device, comprising a feeding and conveying module, wherein a primary cooling unit, a secondary cooling unit, an online detection unit, and a finished product collection unit are sequentially arranged along the material transport direction of the feeding and conveying module; The primary cooling unit includes a coolant tank and a loading robot. The loading robot is used to place the hot melt adhesive body, which has been preliminarily cooled by the coolant tank, onto the feeding and conveying module. The secondary cooling unit includes a circulating conveyor and a transfer mechanism. The transfer mechanism is used to transfer the hot melt adhesive body on the feeding conveyor module to the circulating conveyor for forced air cooling. The online detection unit includes a detection mechanism for detecting the state of the hot melt adhesive body; The finished product collection unit includes a collection robot, which is used to transfer the cooled and molded hot melt adhesive body from the feeding and conveying module to the finished product collection box.

[0007] Preferably, the primary cooling unit further includes a coolant circulation pump and a liquid-cooled heat exchanger, and the coolant tank is connected to the liquid-cooled heat exchanger through the coolant circulation pump to form a closed-loop coolant circulation circuit.

[0008] Preferably, the transfer mechanism in the secondary cooling unit includes an air-cooling unit base, a workpiece reversing mechanism, and an adsorption transfer robot. The workpiece reversing mechanism is fixed on the air-cooling unit base, and the adsorption transfer robot is connected to the output end of the workpiece reversing mechanism.

[0009] Preferably, the secondary cooling unit further includes an air-cooled cavity frame and a cooling blower, the circulating conveyor is installed on the top of the air-cooled cavity frame, and the cooling blower is disposed inside the cavity formed by the air-cooled cavity frame and the protective cover.

[0010] Preferably, the detection mechanism in the online detection unit includes a detection unit base, a clamping and transfer module, and a fixed-point air cooler. The clamping and transfer module is fixed on the detection unit base and is used to clamp and move the hot melt adhesive body to the detection station.

[0011] Preferably, a temperature sensor is provided at the end of the clamping and transfer module.

[0012] Preferably, the collecting robot in the finished product collecting unit includes a support, a lateral drive mechanism, a lifting drive mechanism, and a gripping component disposed at the output end of the lifting drive mechanism; the lateral drive mechanism is fixed to the top of the support, and the lifting drive mechanism is connected to the output end of the lateral drive mechanism.

[0013] Preferably, the hot melt adhesive body adheres to the surface of the feeding and conveying module during the conveying process.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This hot melt adhesive cooling and molding device, through the coordinated operation of a multi-stage cooling system, an automated connection mechanism, an online detection unit, and a finished product collection unit, effectively improves the efficiency and quality of hot melt adhesive cooling and molding, enhances the degree of production automation, and meets the needs of large-scale production. Its specific details are as follows: First, a multi-stage cooling system is constructed by setting up a primary cooling unit and a secondary cooling unit. The primary cooling unit uses a coolant tank to achieve initial and efficient cooling of the hot melt adhesive body. Combined with the closed-loop circulation loop formed by the coolant circulation pump and the liquid-cooled heat exchanger, the coolant temperature is kept stable, improving the initial cooling efficiency. The secondary cooling unit transfers the hot melt adhesive body to the circulation conveyor for forced air cooling through a transfer mechanism. Combined with the enhanced airflow environment formed by the air-cooled cavity frame and the cooling blower, the residual heat inside the hot melt adhesive body can be fully dissipated, avoiding the impact of uneven cooling on molding accuracy and improving the cooling depth and uniformity.

[0015] Secondly, the loading robot in the primary cooling unit can automatically transfer the hot melt adhesive body to the feeding and conveying module after initial cooling. The adsorption and transfer robot in the secondary cooling unit and the workpiece reversing mechanism realize the automated connection of the hot melt adhesive body in different cooling stages, reducing manual intervention. The online detection unit transfers the hot melt adhesive body to the detection station through the clamping and transfer module. With the help of end temperature sensors and other detection components, it can monitor the key status parameters such as temperature and shape of the hot melt adhesive body in real time, which facilitates the rapid identification and rejection of unqualified products, improving product quality stability and production automation level.

[0016] Finally, the collection robot of the finished product collection unit can automatically transfer the cooled and formed hot melt adhesive body to the finished product collection box through the coordinated action of the horizontal drive mechanism and the lifting drive mechanism, replacing manual handling and collection. This not only reduces labor costs but also avoids damage to finished products caused by manual operation, while significantly improving overall production efficiency and adapting to large-scale production scenarios.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0020] like Figure 1-7 As shown, this utility model provides a hot melt adhesive cooling and molding device, aiming to solve the problems of low cooling efficiency, unstable molding quality, and low automation in traditional hot melt adhesives. By setting up a two-stage cooling structure of "primary liquid cooling + secondary air cooling," coupled with an online detection and automated collection module, the entire process of hot melt adhesive cooling from initial cooling to finished product collection is automated. Simultaneously, position sensors are added to each gripping robotic arm to improve gripping accuracy. This device is suitable for cooling and molding various blocky, columnar, and other regular-shaped hot melt adhesive bodies, and is particularly suitable for mass production scenarios.

[0021] In this embodiment, the hot melt adhesive cooling and molding device uses the feeding and conveying module 1 as the core conveying line, and sequentially connects the primary cooling unit 2, secondary cooling unit 3, online detection unit 4, and finished product collection unit 5 along the material transport direction. Each unit is linked and controlled by an electrical control system to achieve coordinated operation. Specifically, the primary cooling unit 2 rapidly cools and shapes the hot melt adhesive body 6, the secondary cooling unit 3 performs deep cooling, the online detection unit 4 detects molding defects, and the finished product collection unit 5 automates collection, forming a closed-loop production chain of "cooling-detection-collection".

[0022] like Figure 1-2 As shown, the feeding conveyor module 1 adopts a belt conveyor structure, consisting of a conveyor belt, drive motor, drive roller, driven roller, and frame. The conveyor belt is made of high-temperature resistant and wear-resistant polyurethane material, with a frosted surface to increase friction. The hot melt adhesive body 6 adheres tightly to the surface of the conveyor belt during conveying, ensuring no deviation occurs. The frame is constructed from aluminum alloy profiles and has leveling feet at the bottom, allowing for height adjustment based on the flatness of the workshop floor to ensure the conveyor belt remains horizontal.

[0023] The primary cooling unit 2, as the first cooling process of the hot melt adhesive body 6, mainly consists of a feeding robot 201, a coolant tank 202, a coolant circulation pump 203, and a liquid-cooled heat exchanger 204. Its core function is to achieve rapid cooling of the hot melt adhesive body 6 by immersing it in coolant, so as to avoid deformation during subsequent transportation.

[0024] The coolant tank 202 is an open tank made of stainless steel, containing a mixture of industrial ethanol and water (mass ratio 1:3) as a coolant. Level and temperature sensors are installed on the side walls of the tank to monitor the coolant level and temperature in real time. The inlet of the coolant tank 202 is connected to the output of the coolant circulation pump 203 via a pipe, and the outlet is connected to the input of the liquid-cooled heat exchanger 204 via a pipe. The output of the liquid-cooled heat exchanger 204 is then connected to the input of the coolant circulation pump 203 via a pipe, forming a closed-loop coolant circulation circuit. The liquid-cooled heat exchanger 204 uses a finned heat exchanger, coupled with a cooling fan to accelerate heat exchange and ensure the coolant temperature remains stable at 25-30℃.

[0025] The loading robot 201 is mounted on a bracket on one side of the feeding and conveying module 1. It adopts a three-axis Cartesian coordinate robot structure, including an X-axis moving module, a Y-axis moving module, a Z-axis lifting module, and an end effector gripper. The gripper is a pneumatic gripper, with a silicone pad wrapped inside to prevent damage to the hot melt adhesive body 6. A laser position sensor (model: OMRONE3Z-LS63) is embedded inside each of the two gripping arms of the gripper. The sensor's detection direction is perpendicular to the gripping surface of the gripper, which can detect the position coordinates of the hot melt adhesive body 6 in the coolant in real time. The electrical control system calculates the relative position between the gripper and the hot melt adhesive body 6, and drives each axis module to move precisely to ensure that the gripper stably grips the hot melt adhesive body 6. The operation flow of the loading robot 201 is as follows: gripping the hot melt adhesive body 6 after preliminary cooling in the coolant (cooling time 30-60s) → moving it above the feeding and conveying module 1 → precisely placing it on the conveyor belt.

[0026] like Figure 3-5 As shown, the secondary cooling unit 3 is used to perform deep forced air cooling on the hot melt adhesive body 6 after primary cooling, ensuring that its temperature drops to room temperature to complete the shaping. It mainly consists of a transfer mechanism, a circulating conveyor 305, an air-cooled cavity frame 304, a protective cover 306, and a cooling blower 307.

[0027] The transfer mechanism includes an air-cooled unit base 301, a workpiece reversing mechanism 302, and an adsorption transfer robot 303. The air-cooled unit base 301 is made of cast iron and is fixed to the ground with expansion bolts, providing stable support for the entire transfer mechanism. The workpiece reversing mechanism 302 is a rotary cylinder (model: SMCMSQB10A) fixed on the air-cooled unit base 301. Its output end is connected to the adsorption transfer robot 303, which can drive the robot to rotate 0-180°, so that the hot melt adhesive body 6 can be flipped over for cooling. The end of the adsorption transfer robot 303 is a vacuum suction cup assembly (composed of 4 vacuum suction cups with a diameter of 50mm). The suction cups are made of nitrile rubber and are adapted to the surface curvature of the hot melt adhesive body 6. To improve gripping accuracy, three diffuse reflection position sensors (model: SICKWT18-3P430) are evenly arranged circumferentially on the mounting plate of the vacuum suction cup assembly. The sensor detection distance is 5-100mm, which can detect the top position and edge contour of the hot melt adhesive body 6 in real time. The lifting height and horizontal position of the robot are adjusted by the control system to ensure that the suction cup assembly and the surface of the hot melt adhesive body 6 are precisely adhered to, avoiding adsorption displacement.

[0028] The circulating conveyor 305 adopts a chain plate conveyor structure. The chain plate is made of stainless steel and is installed on the top of the air-cooled cavity frame 304. The air-cooled cavity frame 304 is an aluminum alloy frame structure, and a protective cover 306 is installed on the outside. Together, they form a closed air-cooled cavity. There are 3 cooling blowers 307, which are installed in the center of the air-cooled cavity. The air outlet faces the center of the cavity and is at a 45° angle to the chain plate conveyor. The blowing direction is inclined along the conveying direction of the hot melt adhesive body 6, and the wind speed can be adjusted by a frequency converter (adjustment range: 3-8m / s).

[0029] like Figure 6 As shown, the online detection unit 4 is located between the discharge end of the secondary cooling unit 3 and the finished product collection unit 5. It is used to detect the cooling state, dimensional accuracy and surface defects of the hot melt adhesive body 6. It mainly consists of a detection unit base 401, a clamping and transfer module 402, a fixed-point air cooler 403 and detection components.

[0030] The detection unit base 401 is a steel structure platform with a marble countertop to ensure detection accuracy. The clamping and transfer module 402 is fixed to the marble countertop and adopts a four-axis industrial robot structure with a pneumatic chuck at the end. The inner side of the chuck has anti-slip textures. To achieve precise clamping, a contact position sensor (model: KEYENCEGT2-H12K) is installed on each of the two grippers of the chuck. When the gripper contacts the hot melt adhesive body 6, the sensor provides a real-time contact signal, and the control system immediately controls the gripper to stop clamping and maintain a constant clamping force (adjustable clamping force range: 5-15N) to avoid excessive clamping that could deform the hot melt adhesive body 6. A temperature sensor (model: IRTP-01) is also installed at the end of the clamping and transfer module 402. The detection probe of the temperature sensor faces the surface of the hot melt adhesive body 6 and can detect its surface temperature in real time to determine whether the cooling is up to standard (standard temperature ≤40℃).

[0031] The fixed-point air cooler 403 is a small vortex tube cooler installed on the side of the inspection station. Its outlet is directed at the localized high-temperature area of ​​the hot melt adhesive body 6. When the temperature sensor detects that the local temperature exceeds the limit, the fixed-point air cooler 403 automatically turns on to provide supplemental cooling to that area. The inspection components include an industrial camera (model: Baslerac A1920-40gc) and a laser diameter gauge (model: Micro-EpsilonoptoNCDT1420). The industrial camera is mounted directly above the inspection station via a bracket to capture surface images of the hot melt adhesive body 6. The image processing system identifies surface defects such as cracks and dents. The laser diameter gauge is installed on both sides of the inspection station to measure the diameter or thickness of the hot melt adhesive body 6 with an accuracy of ±0.01mm.

[0032] like Figure 7As shown, the finished product collection unit 5 is used to transfer the qualified hot melt adhesive body 6 from the feeding and conveying module 1 to the finished product collection box 504 to achieve automated collection. It mainly consists of a collection robot and the finished product collection box 504.

[0033] The collecting robot includes a support 501, a lateral drive mechanism 502, a lifting drive mechanism 503, and a gripping component. The support 501 is an aluminum alloy gantry structure, spanning above the feeding and conveying module 1. The lateral drive mechanism 502 is a ball screw slide module, fixed to the top of the support 501. Its slide is connected to the lifting drive mechanism 503, which can drive the lifting drive mechanism 503 to move along the width direction of the feeding and conveying module 1. The lifting drive mechanism 503 is a pneumatic lifting cylinder, whose output end is connected to the gripping component to realize the up and down lifting of the gripping component. The gripping component is a multi-claw pneumatic gripper. Each claw finger of the gripper is embedded with a miniature laser position sensor (model: Panasonic HG-C1030), which can detect the relative position of the claw finger and the hot melt adhesive body 6 in real time. The control system adjusts the actions of the lateral drive mechanism 502 and the lifting drive mechanism 503 to ensure that the gripper accurately grasps the hot melt adhesive body 6. The finished product collection box 504 is an open box made of plastic with internal partitions. The collection robot can place the hot melt adhesive body 6 into different partitions according to its specifications. The bottom of the box is equipped with casters for easy transfer of finished products.

[0034] Working principle: Before using this hot melt adhesive cooling and molding device, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 7 As shown, the loading robot 201 first grabs the hot melt adhesive body 6 to be cooled and accurately places it into the coolant tank 202 of the primary cooling unit 2, using the coolant to perform preliminary cooling of the hot melt adhesive body 6.

[0035] To ensure a stable coolant temperature, the coolant circulation pump 203 starts, transporting the coolant in the coolant tank 202 to the liquid-cooled heat exchanger 204. After heat exchange and cooling, the coolant flows back to the coolant tank 202, forming a closed-loop coolant circulation circuit.

[0036] After initial cooling is completed, the loading robot 201 moves again to remove the hot melt adhesive body 6 from the coolant tank 202 and place it stably on the feeding conveyor module 1, which then transports it to the next unit.

[0037] When the hot melt adhesive body 6 arrives at the secondary cooling unit 3 along with the feeding and conveying module 1, the transfer mechanism starts to work. The workpiece reversing mechanism 302, which is fixed on the air-cooling unit base 301, drives the adsorption and transfer robot 303 to move, and the adsorption and transfer robot 303 accurately grasps the hot melt adhesive body 6.

[0038] The workpiece reversing mechanism 302 adjusts the angle and position of the adsorption transfer robot 303 to transfer the hot melt adhesive body 6 into the cavity composed of the air-cooled cavity frame 304 and the protective cover 306, and places it on the circulating conveyor 305.

[0039] The cooling blower 307 starts and delivers cold air into the cavity; at the same time, the circulating conveyor 305 starts to operate, forcibly cooling the hot melt adhesive body 6 to achieve deep cooling.

[0040] After secondary cooling is completed, the adsorption transfer robot 303 puts the hot melt adhesive body 6 back into the feeding and conveying module 1 and continues to convey it to the online detection unit 4.

[0041] After the feeding and conveying module 1 conveys the hot melt adhesive body 6 to the online detection unit 4, the clamping and transfer module 402, which is fixed on the detection unit base 401, moves to precisely clamp the hot melt adhesive body 6 and move it to the preset detection station.

[0042] A temperature sensor installed at the end of the clamping and transfer module 402 detects the surface temperature of the hot melt adhesive body 6 in real time to determine whether its cooling status meets the standard; if the temperature is too high, the fixed-point air cooler 403 is activated to provide local auxiliary cooling for the hot melt adhesive body 6.

[0043] After the inspection is completed, if the hot melt adhesive body 6 is in qualified condition, the clamping and transfer module 402 will send it back to the feeding and conveying module 1; if it is unqualified, it will be transferred to the waste area according to the preset program to avoid entering the subsequent process.

[0044] The hot melt adhesive body 6, which has passed the online inspection, arrives at the finished product collection unit 5 along with the feeding and conveying module 1. The collection robot starts working, and the horizontal drive mechanism 502, which is fixed on the top of the bracket 501, drives the lifting drive mechanism 503 to move laterally, so that the gripping component at the output end of the lifting drive mechanism 503 is aligned with the hot melt adhesive body 6.

[0045] The lifting drive mechanism 503 drives the gripping component to descend. After the gripping component accurately grips the hot melt adhesive body 6, the lifting drive mechanism 503 rises, and the horizontal drive mechanism 502 moves again to transfer the hot melt adhesive body 6 above the finished product collection box 504.

[0046] The gripping component is released, and the hot melt adhesive body 6 falls into the finished product collection box 504, completing a complete cooling, molding, and collection process; then each unit is reset, ready to receive the next batch of hot melt adhesive body 6.

[0047] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
