Description

Technical Field

[0001] This utility model relates to the field of hot melt press technology, specifically a cylinder-driven hot melt press. Background Technology

[0002] A cylinder-driven hot melt press is an automated processing equipment that uses compressed air as a power source. Through a cylinder-driven actuator, it achieves precise pressure output and displacement control. Combined with a hot melt heating component, it heats and melts thermoplastic materials, then applies preset pressure, causing the workpieces to be joined to bond, weld, or press under the combined action of heat and pressure. It is widely used in industrial scenarios such as electronic component assembly, plastic product splicing, and packaging sealing. However, the current processing flow of this type of equipment has significant limitations: workers must manually place the workpiece at the pressing station, then start the equipment to complete the hot melt pressing process. Only after the entire processing is completed can the finished product be removed and a new workpiece be replaced. This single-process serial operation mode of "loading-processing-unloading" results in the equipment being idle during the workpiece changeover phase, leading to a low percentage of effective working time and difficulty in improving production efficiency. Meanwhile, the crimping part of the equipment, as the core actuator, is always located above the workstation, with the workpiece changing area below it. When workers pick up and put down workpieces in this area, their hands need to be frequently extended directly under the crimping part. If the equipment is accidentally triggered or the stroke control fails, the crimping part may accidentally descend, causing hand crushing injuries, which poses a great safety hazard and restricts the safe and efficient application of the equipment in modern production.

[0003] Therefore, this utility model provides a cylinder-driven hot melt press. Utility Model Content

A pressing part is provided below the top plate. A cross-shaped rotating seat is rotatably connected to the top of the support base. Four carrying plates are mounted on the top of the cross-shaped rotating seat. The four carrying plates rotate sequentially to a position below the pressing part. A safety baffle is provided on one side of the pressing part. A support strip is provided on the top of the safety baffle. The support strip is installed on the side wall of the pressing part. The safety baffle covers the front side of the lower carrying plate. Two return springs are installed between the safety baffle and the support strip. A fan is provided on one side of the support base. A guide pipe is installed on the top of the fan. An exhaust plate is installed at one end of the guide pipe. The exhaust plate is located on the top of one of the carrying plates.

[0011] Beneficial effects

[0012] Compared with the prior art, the present invention has the following advantages:

[0020] 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.

[0021] Please see Figure 1-4 A cylinder-driven hot melt press includes a press support 1, which includes a support base 11, a top plate 12, and two side plates 13. A pressing part 14 is provided below the top plate 12. A cross rotating seat 2 is rotatably connected to the top of the support base 11. Four carrying plates 21 are installed on the top of the cross rotating seat 2. The four carrying plates 21 rotate sequentially to a position below the pressing part 14. A safety baffle 3 is provided on one side of the pressing part 14. A support strip 31 is provided on the top of the safety baffle 3. The support strip 31 is installed on the side wall of the pressing part 14. The safety baffle 3 covers the front side of the lower carrying plate 21. Two return springs 32 are installed between the safety baffle 3 and the support strip 31. A fan 4 is provided on one side of the support base 11. A guide pipe 41 is installed on the top of the fan 4. An exhaust plate 42 is installed at one end of the guide pipe 41. The exhaust plate 42 is located on the top of one of the carrying plates 21.

[0022] Specifically, the pressing part 14 is raised and lowered by a cylinder driven by the top plate 12 of the press support 1. The pressing part has a built-in hot melt heating component that can heat the thermoplastic material to a molten state. The cross-shaped rotating seat 2 at the top of the support base 11 can rotate around its central axis. The four carrying plates 21 at the top of the cross-shaped rotating seat 2 rotate sequentially to the working position below the pressing part 14. When one of the carrying plates 21 rotates to the position directly below the pressing part 14, the pressing part 14 moves downward under the cylinder drive, applying a preset pressure to the workpiece on the carrying plate 21, and completing the process with the hot melt component. During the bonding / welding / pressing process, the support strip 31 on the side wall of the pressing part 14 drives the safety baffle 3 to move downwards synchronously. The return spring 32 is compressed, and the safety baffle 3 blocks the front of the workpiece plate 21. During the processing at this station, the worker can perform loading / unloading operations on the other three workpiece plates 21 located outside the pressing part 14. When the processing at the current station is completed, the pressing part 14 moves upwards to reset, the safety baffle 3 resets under the action of the return spring 32, and the cross rotating seat 2 rotates to allow the next workpiece-loaded workpiece plate 21 to be placed on it. The workpiece is moved to the area below the pressing section 14, and the processed workpiece 21 rotates to the outer station. At this time, the fan 4 on one side of the support base 11 delivers airflow through the air duct 41 to the exhaust plate 42 at the top of the workpiece 21 in the outer station to cool the processed workpiece. This process is repeated cyclically, realizing parallel operation of processing and workpiece replacement. Through the multi-station design of the cross rotating seat 2, the single-process serial operation of "loading-processing-unloading" is converted into parallel operation. When one of the workpieces 21 is being processed under the pressing section 14, The remaining workpieces can be changed simultaneously on the other workpiece plates 21, avoiding downtime and idleness of the equipment during the workpiece change phase, increasing the effective working time ratio and solving the problem of low production efficiency. At the same time, the safety baffle 3 blocks the front side of the workpiece plate 21 below the pressing part 14 during the processing phase, so the worker only operates on the workpiece plate 21 outside the pressing part 14, without having to put their hands under the pressing part 14. With the work position switching of the cross rotary seat 2, the risk of hand squeezing when the pressing part 14 is accidentally triggered or malfunctions is completely avoided, solving the safety hazard problem.

[0023] In one embodiment of this utility model, such as Figures 1-4 As shown, a number of spherical rolling elements 22 are installed at the bottom of the cross-shaped rotating base 2, and the number of spherical rolling elements 22 are slidably connected to the top of the support base 11.

[0024] Specifically, several spherical rolling bodies 22 installed at the bottom of the cross rotary seat 2 are in contact with the top of the support base 11. When the cross rotary seat 2 rotates to switch work positions, the spherical rolling bodies 22 roll on the top surface of the support base 11, converting the sliding friction between the cross rotary seat 2 and the support base 11 into rolling friction.

[0025] In one embodiment of this utility model, such as Figures 1-4As shown, the top of the support base 11 is provided with a clearance groove 111, and a drive motor 23 that is connected to the cross rotating seat 2 is installed in the clearance groove 111.

[0026] Specifically, the clearance groove 111 at the top of the support base 11 provides installation space for the drive motor 23. The drive motor 23 is connected to the cross rotating seat 2 for transmission. When the equipment completes the processing of the current station, the drive motor 23 starts and outputs power, driving the cross rotating seat 2 to rotate at a preset angle, thereby realizing the automatic station switching of the workpiece plate 21.

[0027] In one embodiment of this utility model, such as Figures 1-4 As shown, two guide rods 33 are installed at the top of the safety barrier plate 3. Both guide rods 33 are slidably connected to the inner wall of the support plate 31. The reset spring 32 is sleeved on the outer side of the corresponding guide rod 33. A linkage rod 34 is provided at the top of the support plate 31. The linkage rod 34 is installed at the top of the two guide rods 33.

[0028] Specifically, the two guide rods 33 at the top of the safety barrier 3 pass through the inner wall of the support strip 31. When the pressing part 14 drives the support strip 31 downward, the guide rods 33 slide along the inner wall of the support strip 31 to ensure that the safety barrier 3 maintains stable vertical lifting and lowering. At the same time, the return spring 32 sleeved on the outside of the guide rods 33 is compressed. When the pressing part 14 moves upward to reset, the elastic force of the return spring 32 pushes the safety barrier 3 upward synchronously. The linkage rod 34 at the top of the guide rods 33 can limit the sliding stroke of the guide rods 33 to prevent them from falling out of the support strip 31.

[0029] In one embodiment of this utility model, such as Figures 1-4 As shown, the bottom of the safety barrier plate 3 has a slot 35, which is engaged with the top of the cross rotating seat 2.

[0030] Specifically, when the crimping part 14 drives the safety barrier 3 downward, the latch 35 at the bottom of the safety barrier 3 engages with the top of the cross rotating seat 2, so that the safety barrier 3 and the cross rotating seat 2 form a relatively fixed connection during the processing stage, preventing them from shifting due to equipment vibration or external force, and ensuring reliable shielding of the operating area below the crimping part 14.

[0031] In one embodiment of this utility model, such as Figures 1-4 As shown, a U-shaped frame 43 is installed on one side of the fan 4. The U-shaped frame 43 is installed on one side of the support base 11, and the exhaust plate 42 is installed on the top side of the U-shaped frame 43.

[0032] Specifically, the U-shaped frame 43 provides stable support for the fan 4, while its top side provides a mounting carrier for the exhaust plate 42, so that the exhaust plate 42 can be accurately fixed at the top of the target loading plate 21. When the cross rotating seat 2 drives the processed workpiece to rotate to the bottom of the exhaust plate 42, the cooling airflow generated by the fan 4 is transported to the exhaust plate 42 through the air guide pipe 41 and blown in a direction towards the workpiece to achieve rapid cooling. The structural design of the U-shaped frame 43 ensures that the fan 4 and the exhaust plate 42 maintain a stable position during equipment operation, avoiding displacement of components due to airflow impact or equipment vibration.

[0033] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0034] Working principle: The pressing part 14 is raised and lowered by a cylinder driven by the top plate 12 of the press support part 1. The pressing part 14 has a built-in hot melt heating component that can heat the thermoplastic material to a molten state. The cross rotating seat 2 at the top of the support base 11 rotates flexibly under the support of the spherical rolling body 22 at its bottom. The bottom is powered by the drive motor 23 in the clearance groove 111, which drives the four top carrying plates 21 to rotate sequentially to the working position below the pressing part 14. When a carrying plate 21 rotates to the position directly below the pressing part 14, the pressing part 14 moves down to apply pressure, and completes the workpiece processing in conjunction with the hot melt component. At the same time, the side wall support plate 31 of the pressing part 14 drives the safety baffle 3 to move down synchronously. Its bottom latch 35 engages and fixes with the cross rotating seat 2, and the top guide slide rod 33 slides along the support plate 31 to ensure stability. When the return spring 32 is compressed, the safety baffle 3 reliably blocks the front of the workpiece 21. During processing, the worker can simultaneously load / unload the workpiece on the three outer workpieces 21. After processing, the pressing part 14 moves upward, and the safety baffle 3 resets under the action of the return spring 32. The linkage rod 34 limits the travel of the guide slide rod 33 to prevent it from falling off. The drive motor 23 drives the cross rotating seat 2 to rotate, so that the new workpiece workpiece 21 moves to the processing position. The workpiece 21 that has been processed moves to the bottom of the exhaust plate 42. The fan 4 fixed by the U-shaped frame 43 generates airflow on one side of the support base 11 and is transported to the exhaust plate 42 through the air duct 41 to quickly cool the workpiece and prevent the workpiece from being too hot and burning the workers. The whole process is cyclical, realizing parallel processing and workpiece replacement, improving efficiency and ensuring safety.
