Description

Technical Field

[0001] This utility model relates to the field of hot melt adhesive granule production, specifically to a discharge mechanism for a hot melt adhesive granule polishing machine. Background Technology

[0002] Hot melt adhesives play an indispensable role in modern industrial production and daily life due to their solvent-free, rapid curing, and wide bonding range. In the packaging industry, they are widely used for sealing carton edges and affixing labels; in the electronics and electrical appliance field, they can be used for fixing and encapsulating components; and in light industries such as shoemaking and clothing, they are often used for bonding and laminating materials. Hot melt adhesives are produced in a variety of forms, with various physical forms such as blocks, granules, rods, and powders to meet the needs of different application scenarios.

[0003] In the production process of granular hot melt adhesive, polishing is one of the key steps to ensure product quality. Currently, hot melt adhesive granule polishing mainly relies on polishing equipment. Through the mutual friction and collision between granules and between granules and the inner wall of the polishing machine, burrs and impurities on the surface of the granules are removed, thereby improving the smoothness and uniformity of the granule surface. After polishing, the hot melt adhesive granules are discharged through the discharge port set at the bottom of the polishing machine, and gravity allows the granules to fall naturally into the collection container for subsequent packaging, storage and other processes.

[0004] In actual production, for ease of packaging, packaging bags are often placed directly on the ground below the discharge port to receive materials. However, this receiving method has poor stability and lacks an effective fixing device. When discharging, the hot melt adhesive particles constantly impact the bag wall, which can easily cause the packaging bag to tip over. It requires manual attention to fix the position of the packaging bag at all times, or the use of other items to assist in fixing it. This not only increases the labor intensity and reduces production efficiency, but also makes it easy for the packaging bag to shift due to human negligence, causing particles to spill and resulting in material waste. At the same time, cleaning up spilled particles also consumes extra time and effort, which seriously affects the continuity and smoothness of production. Therefore, a discharge mechanism for a hot melt adhesive particle polishing machine is proposed. Summary of the Invention

[0005] Based on this, the purpose of this utility model is to provide a discharge mechanism for a hot melt adhesive particle polishing machine to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a discharge mechanism for a hot melt adhesive particle polishing machine, which is used in the polishing machine. The bottom of the polishing machine is fixedly installed with a discharge port, and clamps are provided on both sides of the discharge port for clamping the mouth of a packaging bag. A connecting rod is fixedly connected to the top of the clamps, and the top of the connecting rod is rotatably connected to the outer wall of the discharge port. A fixing rod is fixedly connected to the middle of the connecting rod, and a hinge rod is rotatably installed at the end of the fixing rod. The hinge rod is rotatably connected to a pedal through a transmission mechanism for foot pressure, and the pedal is rotatably connected to a base. The pedal has a design with one end raised, and a spring is fixedly installed at the bottom of the raised end of the pedal. The other end of the spring is fixedly installed on the base for storing force and resetting the pedal. The transmission mechanism includes a transmission rod and a synchronization assembly, wherein the bottom of the transmission rod is rotatably mounted on one end of the pedal, and the top of the transmission rod is rotatably connected to the hinge rod.

[0007] By adopting the above technical solution, the downward pressure is converted into an upward thrust of the transmission rod by the foot pedal. The hinge rod and connecting rod cause the clamp to rotate around the pivot of the connecting rod, thereby opening outward, which facilitates the packaging bag opening and makes it easier to fix the packaging bag during the receiving process, reducing the workload of manual fixing.

[0008] Furthermore, the synchronization component includes a synchronization rod and a connecting frame, wherein one end of the connecting frame is rigidly connected to the upper outer wall of the transmission rod, and the other end of the connecting frame is rigidly connected to the bottom end of the synchronization rod. The connecting frame has a U-shaped structure, and a gap is provided between the connecting frame and the discharge port.

[0009] By adopting the above technical solutions, interference with the discharge port or clamps during movement is avoided, ensuring the stability and accuracy of synchronous transmission.

[0010] Furthermore, a protrusion is fixedly installed on the outer wall of the discharge port, and a groove corresponding to the protrusion is opened on the inner side of the clamp. The protrusion and the groove work together to reinforce and clamp the opening of the packaging bag, and the clamp is designed to fit the arc shape of the outer wall of the discharge port.

[0011] By adopting the above technical solution, the friction between the clamp and the discharge port is increased by the mechanical interlocking structure, thereby preventing the bag opening from sliding under the action of particle gravity, thus providing double protection for clamping reliability.

[0012] Furthermore, the transmission rod and the synchronizing rod are respectively connected to both ends of the fixed rod via hinged rods, for synchronous transmission between the two ends of the fixed rod.

[0013] By adopting the above technical solution, the transmission rod and the synchronization rod can force the fixed rod to maintain synchronous lifting on both sides, avoiding asynchronous opening and closing of the clamps on both sides caused by unilateral transmission, further ensuring that the bag mouth is evenly clamped, thereby effectively preventing particle leakage or packaging bag falling off due to uneven force on the bag mouth, and improving the overall discharge stability.

[0014] In summary, the present invention has the following main advantages: This invention achieves the clamping and fixing of the packaging bag and the discharge port in three steps: stepping on the pedal to open, putting on the bag, and releasing the pedal to clamp. Foot control replaces manual force, avoiding hand fatigue caused by prolonged hand holding or pressing of the clamp. It can be operated quickly by a single person, and is especially suitable for high-frequency, large-volume material receiving scenarios, reducing manual labor intensity and significantly shortening the preparation time for each material receiving. The transmission rod and synchronization rod ensure that the force is evenly distributed on both sides of the clamp, avoiding uneven clamping force caused by unilateral pressure. The interlocking design of the protrusion and groove greatly improves the connection strength between the clamp and the discharge port, generating multi-directional pressure on the bag opening, effectively preventing the packaging bag from falling off due to excessive weight of granular materials and increased pressure inside the bag during receiving. The whole adopts a mechanical transmission structure without complex electronic components, and is less affected by environmental factors such as dust and humidity, reducing the probability of equipment failure.

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0018] The embodiments of this utility model will be described below based on its overall structure. Example 1

[0019] A discharge mechanism for a hot melt adhesive granule polishing machine, such as Figure 1-4 As shown, it is used in a polishing machine 1. A discharge port 11 is fixedly installed at the bottom of the polishing machine 1, and clamps 12 are provided on both sides of the discharge port 11 to hold the opening of the packaging bag. The two sets of clamps 12 are symmetrically distributed to ensure balanced force on the bag opening and prevent bag opening deviation from affecting material receiving efficiency. A connecting rod 123 is fixedly connected to the top of the clamp 12, and the top of the connecting rod 123 is rotatably connected to the outer wall of the discharge port 11. The connecting rod 123 and the discharge port 11 can rotate flexibly through a hinge shaft, providing a stable rotation fulcrum for the opening and closing of the clamp 12, ensuring stable opening and closing of the clamp 12. A fixing rod 122 is fixedly connected to the middle of the connecting rod 123. The fixing rod 122 and the connecting rod 123 are designed perpendicularly, which can vertically transmit the subsequent transmission force to the connecting rod 123, reducing force loss. A hinge rod is rotatably installed at the end of the fixing rod 122. 136, the hinge rod 136 efficiently converts the action of the transmission mechanism into the rotational power of the connecting rod 123. The hinge rod 136 is rotatably connected to the pedal 132 through the transmission mechanism for foot pressure. Compared with the manually operated clamp 12, the foot-operated method can free the operator's hands, facilitate simultaneous bagging operation, and improve work efficiency. The pedal 132 is rotatably connected to the base 13, which provides stable support for the pedal 132 and prevents displacement or shaking when the pedal 132 is under force. The pedal 132 has a raised end design, and a spring 131 is fixedly installed at the bottom of the raised end of the pedal 132. The other end of the spring 131 is fixedly installed on the base 13 to realize the storage and reset of the pedal 132, ensuring that the extension and retraction direction of the spring 131 is stable and that the pedal 132 can quickly return to the initial state after each operation without manual adjustment. The transmission mechanism includes a transmission rod 133 and a synchronization component. The bottom of the transmission rod 133 is rotatably mounted on one end of the pedal 132, and the top of the transmission rod 133 is rotatably connected to the hinge rod 136. By applying pressure with the foot pedal, the raised end of the pedal 132 converts the downward pressure into an upward pushing force of the transmission rod 133. The hinge rod 136 and the connecting rod 123 cause the clamp 12 to rotate around the pivot of the connecting rod 123, thereby opening outward to facilitate the packaging bag opening and fix the packaging bag during the receiving process, reducing the workload of manual fixing.

[0020] Please see Figure 1-4The synchronization component includes a synchronization rod 134 and a connecting frame 135. The synchronization rod 134 is arranged parallel to the transmission rod 133 to ensure balanced force on both sides. One end of the connecting frame 135 is rigidly connected to the upper outer wall of the transmission rod 133, and the other end of the connecting frame 135 is rigidly connected to the bottom end of the synchronization rod 134, so that the transmission rod 133 and the synchronization rod 134 form a rigid linkage, ensuring that their movements are completely synchronized. The connecting frame 135 has a U-shaped structure, and there is a gap between the connecting frame 135 and the discharge port 11 to avoid interference with the discharge port 11 or the clamp 12 during movement, thus ensuring the stability and accuracy of synchronous transmission.

[0021] Please see Figure 1-4 A protrusion 111 is fixedly installed on the outer wall of the discharge port 11, and a groove 121 corresponding to the protrusion 111 is opened on the inner side of the clamp 12. The depth of the groove 121 is precisely matched with the height of the protrusion 111 and a certain gap is left to ensure that the two can fit tightly when clamping the bag opening. The protrusion 111 and the groove 121 work together to reinforce the clamping of the bag opening. The mechanical interlocking structure increases the friction between the clamp 12 and the discharge port 11, thereby preventing the bag opening from sliding under the action of particle gravity. This provides double protection for clamping reliability. The clamp 12 is designed to fit the outer wall of the discharge port 11 in an arc shape. The arc curvature is completely consistent with the outer wall of the discharge port 11, which can maximize the contact area between the clamp 12 and the bag opening, making the bag opening more evenly stressed.

[0022] Please see Figure 1-4 The transmission rod 133 and the synchronization rod 134 are respectively set at both ends of the fixed rod 122 through the hinge rod 136. They are used to synchronously drive both ends of the fixed rod 122. The transmission rod 133 and the synchronization rod 134 can force both sides of the fixed rod 122 to keep synchronous lifting and lowering, avoiding asynchronous opening and closing of the clamps 12 on both sides caused by unilateral transmission. This further ensures that the bag mouth is evenly clamped, thereby effectively preventing particle leakage or packaging bag falling off due to uneven force on the bag mouth, and improving the overall discharge stability.

[0023] The working principle of this utility model is as follows: When the operator uses a packaging bag to receive materials, he first steps on one end of the pedal 132. The spring 131 at the bottom of the pedal 132 is compressed and retracts to store force. The pedal 132 rotates around the axis hinged to the base 13, causing the other end of the pedal 132 away from the step to tilt upwards. The transmission rod 133, which is rotatably connected to the tilted end, moves upwards accordingly. The transmission rod 133 drives the synchronous rod 134 on the other side of the discharge port 11 to move upwards synchronously through the connecting frame 135. When the transmission rod 133 and the synchronous rod 134 move upwards, they drive the hinge rods 136 on both sides of the discharge port 11 to move upwards at the ends connected to them. When the hinge rod 136 is hinged to the fixed rod 122 at the other end, forming a lever structure, the lifting force is converted into an outward pushing force on the fixed rod 122. After the fixed rod 122 is pushed, it drives the connecting rod 123 fixed to it to expand outward away from the discharge port 11. However, the top of the connecting rod 123 is rotatably connected to the outer wall of the discharge port 11 through the hinge shaft and cannot be moved horizontally. Therefore, the connecting rod 123 rotates around the hinge shaft, which eventually causes the clamp 12 fixed at the bottom of the connecting rod 123 to gradually move away from the discharge port 11. At this time, a gap is formed between the clamp 12 in front of and behind the discharge port 11 and the discharge port 11, which can be fitted with a packaging bag. At this time, the operator puts the bag opening onto the discharge port 11, and then releases the pedal 132. The spring 131 loses the pressure of being stepped on and releases its elastic potential energy, lifting the end of the pedal 132 away from the transmission rod 133. The end that was originally raised and hinged to the transmission rod 133 falls back into the base 13. The transmission rod 133 and the synchronizing rod 134 descend as the pedal 132 falls. The hinge rod 136 returns to its original position after losing the upward force. The return of the hinge rod 136 drives the fixed rod 122 and the connecting rod 123 to move back, finally causing the two sets of clamps 12 to fall down and re-attach to the outer wall of the discharge port 11, thereby clamping the bag opening. At this time, the protrusion 111 on the outer wall of the discharge port 11 and the groove 121 opened on the inner side of the clamp 12 interlock, further reinforcing the clamping of the bag opening from a structural perspective, and preventing the bag from falling off due to excessive particle weight when receiving material.
