Description

Technical Field

[0001] This utility model relates to the field of foam processing technology, specifically a foam pressing device. Background Technology

[0002] Foam is an elastic material filled with air holes, commonly made of polyurethane, EVA, polyethylene, etc. It is lightweight and has good cushioning, heat insulation, and sound absorption properties, as well as a certain degree of elasticity and sealing. In the process of pressing foam, especially pressing foam into the lid, a prominent practical problem is often encountered. Due to various factors such as the processing precision of the foam itself, the production error of the lid, and the positioning deviation of the two during placement, it is often difficult to achieve precise alignment between the side of the foam and the side of the lid, resulting in a certain positional error. However, the existence of this error directly leads to the fact that the foam is difficult to be smoothly and accurately embedded into the preset installation position of the lid before the pressing operation. Because the edge of the foam is misaligned with the edge of the lid, the foam cannot be embedded as expected. In order to ensure the normal progress of the subsequent pressing operation, the staff has to frequently adjust the posture of the foam, such as manually moving the position of the foam and rotating the angle of the foam. This process not only requires the staff to invest more time and energy, increasing labor costs, but also the frequent adjustment operation can easily affect the overall work rhythm and reduce the overall efficiency of the foam pressing process. Therefore, a foam pressing device is proposed to address the above problems. Utility Model Content

[0016] Please see Figures 1-6 This utility model provides a technical solution: A foam pressing device includes a pressing machine 1, a positioning seat 2 fixed to the top of the pressing machine 1, a pressure rod 3 slidably connected to the inner side of the positioning seat 2, a pressure arm hinged to the top of the pressure rod 3 to provide pressure to the pressure rod 3, a pressure block 4 fixed to the bottom end of the pressure rod 3, and a pressing assembly 5 fixed to the bottom end of the pressure block 4 by a screw. A placement frame 6 is fixed to the lower surface of the pressing machine 1, and the placement frame 6 is located below the pressure plate 53. The pressing assembly 5 includes a connecting seat 51, a support member 52 fixed to the inner side of the connecting seat 51, and a bottom fixed to the inner side of the connecting seat 51. There is a pressure plate 53, and a pre-adjustment mechanism 54 is installed at the bottom of the support member 52. The pre-adjustment mechanism 54 is embedded in the inner side of the pressure plate 53. The pre-adjustment mechanism 54 includes a top rod 541, a rotating sleeve 542 is installed below the top rod 541, and sliding pins 543 are fixed on both sides of the top of the rotating sleeve 542. A spring 544 is installed on the inner side of the rotating sleeve 542, and a spherical pressure head 545 is fixed at the bottom of the rotating sleeve 542. A fixing sleeve 546 is fixed at the bottom of the top rod 541. Inclined grooves 547 for adapting to the sliding pins 543 are opened on both sides of the fixing sleeve 546. Specifically, this device guides the pressure rod 3 to slide stably via the positioning seat 2, the pressure block 4 transmits pressure to the clamping assembly 5, the support member 52 on the connecting seat 51 positions the pre-adjustment mechanism 54, its top rod 541 cooperates with the fixed sleeve 546, and the rotating sleeve 542 moves along the inclined slide groove 547 via the sliding pin 543. The spring 544 provides the restoring force, the spherical pressure head 545 first contacts the foam, and with the rotation, the foam corners retract and embed into the box body, and finally the pressure plate 53 completes the clamping, and the placement frame 6 ensures the stability of the operation; As a further implementation of this solution, the inclined slide 547 is connected to the fixed sleeve 546. The inclined slide 547 has an inclined structure, and the included angle between the inclined slide 547 and the fixed sleeve 546 is 30°. The sliding pin 543 is slidably engaged with the inclined slide 547, which can convert the upward movement of the rotating sleeve 542 into rotation. Through controllable torsion, the foam corner area is shrunk, avoiding manual adjustment and efficiently solving the problem of misalignment between the foam and the box. As a further implementation of this solution, the top rod 541 is fixedly connected to the bottom end of the inner side of the support 52 by bolts. The top rod 541 and the rotating sleeve 542 are located on the same central axis. The interior of the rotating sleeve 542 is a hollow structure. The spring 544 is sleeved on the inner side of the rotating sleeve 542. The top end of the spring 544 is fixedly connected to the lower surface of the top rod 541. The top rod 541 and the rotating sleeve 542 are coaxially designed. With the elasticity of the spring 544, the rotating sleeve 542 is ensured to be subjected to balanced force. This ensures the stable protrusion of the rotating sleeve 542 in its natural state and also achieves smooth contraction and rotation when pressure is applied. As a further implementation of this solution, the lower surface of the spherical pressure head 545 has a spherical structure. The spherical pressure head 545 is located below the pressure plate 53. The lower surface of the spherical pressure head 545 is fixed with anti-slip textures in a circular array. The spherical structure and anti-slip textures of the spherical pressure head 545 increase the contact area with the foam while preventing slippage. It can apply pressure evenly to make the corner area of ​​the foam accurately concave, avoid local excessive compression and damage to the foam, and ensure the pre-deformation effect. As a further implementation of this solution, four support members 52 are provided. The four support members 52 are located at the four corner areas of the inner top of the connecting seat 51. The four corner areas of the pressure plate 53 are provided with mounting grooves 55 for fitting the fixing sleeve 546. The position of the mounting grooves 55 corresponds to the position of the support members 52. The four support members 52 correspond to the layout of the four corners of the foam. Combined with the positioning of the mounting grooves 55, the pre-adjustment mechanism 54 is precisely applied to the corner areas of the foam to achieve synchronous shrinkage and deformation, ensuring that the foam is stably embedded into the box and improving the embedding accuracy. As a further implementation of this solution, the lower surface of the fixed sleeve 546 is flush with the lower surface of the pressure plate 53. The inner side of the fixed sleeve 546 is provided with a circular array of lubrication grooves 548. The lubrication grooves 548 are connected to the inclined slide grooves 547. Sufficient lubricating oil can be filled into the lubrication grooves 548. The lubricating oil forms an oil film, which can reduce the wear of the components, ensure the smooth operation of the rotating sleeve 542 and the sliding pin 543, extend the service life of the mechanism, and maintain long-term stable operation capability.

[0017] Workflow: Place the box and foam of the appropriate shape at the top of the placement rack 6 with the box at the bottom and the foam stacked on top. Use external clamps to limit and fix the box to ensure that the box is stable in subsequent operations. At this time, the pre-adjustment mechanism 54 is in its natural state. Under the action of the spring 544, the rotating sleeve 542 moves down and protrudes relative to the fixed sleeve 546. The sliding pin 543 is located at the bottom of the inner side of the inclined slide groove 547. The spherical pressure head 545 protrudes from the bottom surface of the pressure plate 53. The four pre-adjustment mechanisms 54 correspond to the positions of the foam near the four corner areas. The pressure arm swings downward, applying downward pressure to the pressure rod 3. The pressure rod 3 slides down along the inner side of the positioning seat 2, driving the pressure block 4 to move the clamping assembly 5 downward as a whole. When the connecting seat 51 moves downward, the protruding rotating sleeve 542 and the lower spherical pressure head 545 first contact the four corner areas of the foam. The spherical pressure head 545 applies pressure to the corner areas of the foam. Utilizing the good deformation characteristics of the foam due to its dense pores, the contact area is concave and shrinks. As the pressure continues to increase, the pressure gradually counteracts the elastic force of the spring 544. The spring 544 is compressed and shrinks, driving the rotating sleeve 542 to move upward along the fixed sleeve 546. During this process, the sliding pin 543 cooperates with the inclined slide groove 547 to drive the rotating sleeve 542 to rotate. The rotation angle is about 15°. This slight twisting causes the four corner areas of the foam to shrink and deform inward, reducing the volume of the outer side of the foam, so that it can be quickly embedded into the preset installation position of the box. When the sliding pin 543 moves to the top of the inner side of the inclined slide groove 547, the rotating sleeve 542 is fully embedded in the fixed sleeve 546, and the spherical pressure head 545 and the bottom of the pressure plate 53 are at the same level. At this time, the pressure plate 53 begins to perform overall pressing of the foam, firmly pressing the foam onto the box. It should be added that the lubricating oil in the lubrication groove 548 inside the fixed sleeve 546 forms an oil film, reducing the wear between the rotating sleeve 542 and the fixed sleeve 546, and between the sliding pin 543 and the inclined slide groove 547, ensuring smooth operation and service life of the mechanism. After the pressing operation is completed, the operating pressure arm swings upward, driving the pressure rod 3 to move upward. The pressure block 4 drives the pressing assembly 5 to move upward synchronously, detaching from the foam. The spring 544 restores its elasticity, pushing the rotating sleeve 542 downward. The sliding pin 543 returns to the bottom of the inner side of the inclined slide groove 547, and the spherical pressure head 545 protrudes from the bottom surface of the pressure plate 53 again. The device returns to its initial state, waiting for the next foam pressing operation.
